DESCRIPTION REPORT OF THE SYSTEM INVENTION PATENT
OF ELECTRICALLY HEATED AEROSOL GENERATION.
[1] The present invention relates to an electrically heated aerosol generation system that comprises at least one electric heater to heat an aerosol-forming substrate. The present invention finds a specific application as an electrically heated smoking system. The invention also relates to an improved heater for an electrically heated aerosol generation system.
[2] WO-A-2007/078273 describes an electric smoking tool. A liquid is stored in a container which communicates with a heater vaporizer, powered by a battery supply, through a series of small openings. The heater is in the form of an electric heater spiral wrapped around an electrically insulating support. In use, the heater is activated by the user's mouth to turn on the battery power supply. Suction over a nozzle by a user causes air to be sucked through holes in the container, over the heater vaporizer, into the nozzle and subsequently into the user's mouth.
[3] A disadvantage of such a proposed smoking utensil is that it is relatively difficult to manufacture such a heater. Therefore, it is an objective of the invention to overcome this and other disadvantages of the prior art.
[4] According to a first aspect of the present invention, an electrically heated aerosol generating system is provided to receive an aerosol-forming substrate, the system comprising at least one electric heater to heat the aerosol-forming substrate to form the aerosol, the heater comprising a heating element of a first cross section electrically connected to a plurality of elements
Petition 870190104476, of 10/16/2019, p. 6/68
2/55 elongated support ments. Each support element having a larger cross section than the first cross section and in which at least one of the support elements is integrally formed with the heating element.
[5] The provision of a heater integrally formed in an electrically heated aerosol generation system simplifies the manufacture of the heater and the heating element. In addition, the provision of a heater with a heating element and an integral support element or elements simplifies the assembly of the aerosol generation system as the heater can be readily folded, and the support elements fit into slots in a housing of the smoking system to hold the heater in position.
[6] Having support elements which have a greater cross section than that of the heating element has the advantage that the supporting elements heat less than the heating element portion of the heater. This reduces the amount of energy required to power the heater. Support elements with a larger cross section are also more rigid than the heating element, and therefore the support elements provide good structural support for the heating element. The provision of support elements that have a greater cross section than that of the heating elements can be achieved by cutting the heater from a sheet of material which is thicker in the region from which the electrical support elements are formed, but thinner in the region from which the heating element is formed. This means that the heating element portion has a higher resistance than the supporting elements. In addition, the support elements are more rigid than the heating element. Sheet material of varying thickness can be produced

3/55 by a chemical attack process. The production of the sheet material heater simplifies manufacturing.
[7] Preferably, the aerosol generation system is a smoking system.
[8] In a preferred embodiment of the electrically heated aerosol generation system, the aerosol-forming substrate is a liquid aerosol-forming substrate. In a preferred embodiment, the electrically heated aerosol generation system further comprises a liquid storage portion. Preferably, the liquid aerosol-forming substrate is stored in the liquid storage portion. In one embodiment, the electrically heated aerosol generation system still comprises a capillary wick in communication with the liquid storage portion. It is also possible for a capillary wick to contain the liquid to be provided without a liquid storage portion. In this mode, the capillary lock can be preloaded with liquid.
[9] Preferably, the capillary wick is arranged to be in contact with the liquid within the liquid storage portion. In this case, in use, the liquid is transferred from the liquid storage portion towards the heater by a capillary action on the capillary wick. In one embodiment, the capillary wick has a first end and a second end, the first end extending into the liquid storage portion for contact with the liquid therein and the at least one electric heater being arranged to heat the liquid in the second end. When the heater is activated, the liquid at the second end of the capillary wick is vaporized by the heater to form supersaturated steam.
[10] An advantage of providing a portion of storage

4/55 of liquid is that the liquid within the liquid storage portion is protected from oxygen (because oxygen cannot generally enter the liquid storage portion through the capillary wick) and, in some embodiments, from light, so that the risk of liquid degradation is significantly reduced. Therefore, a high level of hygiene can be maintained. The use of a capillary wick that extends between the liquid and the heater, which allows the structure of the system to be relatively simple. The liquid has physical properties, including viscosity, which allow the liquid to be transported through the capillary wick by capillary action. The liquid storage portion is preferably a container. Preferably, the container is opaque, thereby limiting the degradation of the liquid by light. The liquid storage portion may not be refillable. Thus, when the liquid within the liquid storage portion has been used, the smoking system is replaced. Alternatively, the liquid storage portion can be refillable. In this case, the aerosol generation system can be replaced after a certain number of refills of the liquid storage portion. Preferably, the liquid storage portion is arranged to contain liquid for a predetermined number of puffs.
[11] The capillary wick can have a fibrous or spongy structure. For example, the capillary wick can comprise a plurality of fibers or threads. The fibers or threads can generally be aligned in the longitudinal direction of the aerosol generation system. Alternatively, the capillary bushing may comprise a material such as a sponge or foam formed into a rod shape. The rod shape can extend along the longitudinal direction of the aerosol generation system. The wick structure forms a plurality of small holes or tubes, through which the liquid can be transported to

Examples of suitable materials are materials based on ceramics or graphite in the form of sintered fibers or powders. The capillary wick can have any suitable capillarity and porosity in order to be used with different physical properties of liquid such as density, viscosity, surface tension and vapor pressure. The capillary properties of the wick, combined with the properties of the liquid ensure that the wick is always wet in the heating area. If the wick is dry, it can overheat, which can lead to thermal degradation of the liquid.
[12] The electrically heated aerosol generation system can comprise at least one air intake. The electrically heated aerosol generation system may comprise at least one air outlet. The electrically heated aerosol generating system may comprise an aerosol forming chamber between the air inlet and the air outlet. In use, when the heater is activated, the liquid inside the capillary wick is vaporized by the heater to form supersaturated steam. Supersaturated steam is mixed with and charged into the air flow of at least one air inlet. During the flow, the vapor condenses to form an aerosol inside the aerosol forming chamber, and the aerosol is charged in the direction of the air outlet into a user's mouth.
[13] The liquid has physical properties, for example, a boiling point suitable for use in the smoking system: if the boiling point is too high, at least one heater will not be able to vaporize the liquid inside the capillary wick, but, if the boiling point is too low, the liquid can vaporize even without at least one heater being activated. The liquid preferably comprises a tobacco-containing material that comprises flavor compounds

6/55 volatile tobacco which is released from the liquid when heating. Alternatively, or in addition, the liquid may comprise a non-tobacco material. The liquid can include water, solvents, ethanol, plant extracts and natural or artificial flavors. Preferably, the liquid still comprises an aerosol former. Examples of suitable aerosol builders are glycerin and propylene glycol.
[14] Alternatively, the aerosol-forming substrate may be a solid aerosol-forming substrate. The aerosol-forming substrate comprises a tobacco-containing material containing volatile tobacco flavor compounds which are released from the substrate when heated. The aerosol forming substrate may comprise a non-tobacco material. The aerosol-forming substrate may comprise a material that contains tobacco and a material that does not contain tobacco. Preferably, the aerosol forming substrate further comprises an aerosol former. Examples of suitable aerosol builders are glycerin and propylene glycol.
[15] The solid substrate may comprise, for example, one or more of: powders, granules, spheres, scraps, spaghetti, strips or plates containing one or more of: grass leaf, tobacco leaf, tobacco rib fragments , reconstituted tobacco, extruded tobacco such as homogenized tobacco and expanded tobacco. The solid substrate can be in loose form, or it can be provided inside a suitable container or cartridge. Optionally, the solid substrate may contain additional volatile tobacco or non-tobacco flavor compounds to be released upon heating of the substrate.
[16] Optionally, the solid substrate can be provided on or embedded in a thermally stable support. In a preferred embodiment, the support is a tubular support that has a thin layer of the solid substrate deposited on its internal surface, or on
Petition 870190104476, of 10/16/2019, p. 11/68
7/55 its outer surface, or on both its inner and outer surfaces. Such a tubular support may be formed, for example, of a paper, or a material such as paper, a non-woven carbon fiber blanket, a low-mass open mesh wire mesh, or a perforated metal sheet or any other polymer matrix thermally stable. Alternatively, the support may take the form of powders, granules, spheres, scraps, spaghetti, strips or plates. The solid substrate can be deposited on the support surface in the form of, for example, a sheet, foam, gel or paste. The solid substrate can be deposited on the entire surface of the support, or alternatively, it can be deposited in a pattern in order to provide a non-uniform flavor supply during use. Alternatively, the support can be a nonwoven fabric or a bundle of fibers into which the tobacco components have been incorporated. The nonwoven fabric or bundle of fibers may comprise, for example, carbon fibers, natural cellulose fibers, or fibers derived from cellulose.

Petition 870190104476, of 10/16/2019, p. 12/68
8/55 [19] The heating element can be made of an elastic material. This preferably means that the heating element is elastic. The heating element can have any suitable elasticity. This can ensure good contact between the heating element and the aerosol forming substrate. The heating element can be made of a flexible material. This preferably means that the heating element is flexible. The heating element can have any suitable flexibility. The heating element can have a substantially constant width along its length.
[20] The heating element may comprise a flexible heating element that extends between the support elements. The heating element may comprise a sheet of electrically resistive material. The plate can have any suitable shape, as will be further described below. The heating element can be formed by forming a sheet of electrically resistive material. For example, the heating element can be cut from the sheet of electrically resistive material, for example, by a laser or by a chemical or electrical processor by a high pressure water jet. Alternatively, the heating element can be preformed in the desired shape.
[21] In an embodiment in which the heater is an electric heater for an electrically heated smoking system that has a capillary wick to contain a liquid, preferably in use, the support elements are attached adjacent to the capillary wick and the element The heating element extends between the support elements and around the capillary wick.

9/55 described, the heating element can be flexible. The material sheet can have any suitable flexibility. Preferably, the material sheet is elastic. This elasticity results in a spring effect when the heating element is mounted around the capillary wick. This ensures good contact with the capillary wick. This ensures a consistent and repeatable smoking experience. The heating element can extend partially or totally along the capillary wick. The heating element preferably extends around substantially the entire circumference of the capillary wick.
[22] The at least one electric heater can comprise a single heating element. Alternatively, the at least one heater may comprise more than one heating element, for example, two, or three, or four, or five, or six or more heating elements. In this case, each heating element can extend between a support element which can be an electrically positive connector and another support element which can be an electrically negative connector. The heating element or heating elements can be arranged appropriately so as to heat the aerosol forming substrate as efficiently.

[24] The at least one heater may furthermore comprise a disc heater (either end or a combination of a disc heater with heating needles or rods.
[25] In one embodiment, the heating element is in the form of a square wave that extends between the supporting elements. That is, the heating element may comprise portions which extend substantially parallel to the support elements and portions which extend substantially perpendicular to the support elements joining the substantially extending portions.
Petition 870190104476, of 10/16/2019, p. 15/68
11/55 tially parallel to the support elements at alternating ends of the portions extending substantially parallel to the support elements. In one embodiment, the support elements are elongated and the heating element comprises portions that extend substantially parallel to the longitudinal geometric axis of the elongated support elements and portions that extend substantially perpendicular to the longitudinal geometric axis of the elongated support elements joining the extending portions substantially parallel to the longitudinal geometric axis of the elongated support elements at alternating ends of the portions extending substantially parallel to the longitudinal geometric axis of the elongated support elements.
[26] The number and size of the portions that extend substantially parallel to the supporting elements can be varied. The number and size of the portions that extend substantially perpendicular to the support elements can be varied. This can affect the final flexibility of the heating element.
[27] All portions of the heating element can have the same shape and cross-sectional area. Alternatively, some portions of the heating element may have a different cross-sectional shape than other portions of the heating element.
[28] In a preferred embodiment, the portions of the heating element that extend substantially parallel to the support elements have a maximum cross section which is greater than the maximum cross section of the other portions of the heating element. That is to say, the portions which extend substantially parallel to the support elements are thicker, at least in part, in relation to the other portions. Portions that extend substantially parallel to the connectors may not have a section
Petition 870190104476, of 10/16/2019, p. 16/68
12/55 constant cross. In fact, in a preferred embodiment, the portions that extend substantially parallel to the connectors are in the form of lenses, having a larger central cross section than the end cross sections.
[29] In another preferred embodiment, the portions that extend substantially perpendicular to the support elements are substantially semicircular in shape. That is to say, the portions that extend substantially perpendicular to the supporting elements are thicker in relation to other portions and are formed as a semicircle. Preferably, the curved edge of each semicircle is directed away from the portions of the heating element which extend substantially parallel to the support elements.
[30] The inventors of the present invention have found that sometimes with a heating element that has a constant cross section along its length, hot spots can be formed in the middle or at the ends of the heating element. This can result in overheating at certain points. The provision of a portion or portions of the heating element having a larger cross-sectional area reduces the strength of these portions, thereby reducing Joule heating. This can reduce the likelihood of hot spots forming and can provide a more uniform heat distribution.
[31] In one embodiment, the heating element comprises portions that extend diagonally in one direction between a supporting element and another supporting element and portions that extend diagonally in a direction different from the first direction between a supporting element and another supporting element. Support. In one embodiment, the support elements are elongated and the heating element comprises portions that extend diagonally across
Petition 870190104476, of 10/16/2019, p. 17/68
13/55 a direction between an elongated support element and another elongated support element and portions that extend diagonally in a different direction from the first direction between an elongated support element and another elongated support element. In this case, the heating element may be in the form of a substantially triangular wave that extends between the connectors.
[32] Portions that extend diagonally in one direction may be connected to portions that extend diagonally in the other direction by curved portions. In this case, the heating element can take the form of a substantially sine wave that extends between the connectors.
[33] It has been found that the inclusion of portions that extend diagonally in relation to the support elements instead of extending substantially parallel or perpendicular to the support elements, helps with the assembly of the heating element. Specifically, if the electrically heated aerosol generation system includes a capillary wick, this helps with the assembly of the heating element around the capillary wick. In some embodiments, an improved contact between the heating element and the capillary wick can be established. If the portions extending diagonally in one direction are connected to the portions extending diagonally in the opposite direction by curved portions, this can further improve flexibility.
[34] The number, size and angle of portions that extend diagonally in one direction can be varied. The number, size and angle of the portions that extend diagonally in the other direction can be varied. The curvature of the curved portions can be adjusted. This will affect the final flexibility of the heating element.
[35] All portions of the heating element may have
Petition 870190104476, of 10/16/2019, p. 18/68
14/55 the same shape and cross-sectional area. Alternatively, some portions of the heating element may have a different cross-sectional shape than other portions of the heating element. As already described, this can improve the heat distribution.
[36] Various forms of the heating element have been described, but the person skilled in the art will appreciate that any suitable form can be used. In addition, the heating element does not have to have the same shape extending the entire length between the support elements. For example, the heating element can comprise a first heating element section that has a first shape and a second heating element section that has a second shape. Or, additional sections can be included. As already discussed, the shape and other characteristics of the heating element affect aerosol formation and the smoking experience.
[37] Preferably, the at least one electric heater still comprises at least a reinforcement portion adjacent to at least one of the support elements. The at least one reinforcement portion may comprise a material which is less flexible than the heating element. This provides resistance to the heating element. The at least one reinforcement portion can be integrally formed with the heating element. The reinforcement portion can also facilitate a folding operation, which is important for thin heating elements. This may also allow the heater to have more of a spring effect, and may therefore allow the heater, specifically the heating element, to remain close to the aerosol-forming substrate. The reinforcement portion may or may not comprise an electrically conductive material as long as a path for an electric current can still be established between an electrically positive connector and a
Petition 870190104476, of 10/16/2019, p. 19/68

The at least one reinforcement portion between the first heating element portion and the second heating element portion may comprise a material which is less flexible than the heating element. This provides resistance to the heating element. The at least one reinforcement portion can be integrally formed with the heating element. The reinforcement portion may or may not comprise a material it

[40] In one embodiment, the at least one reinforcement amount comprises a reinforcement amount that extends from the electrically negative connector in a direction substantially perpendicular to the electrically negative connector. In one embodiment, the at least one amount of reinforcement comprises an amount of reinforcement extending from the electrically positive connector in a direction substantially perpendicular to the electrically positive connector.

17/55 at least partially around the capillary wick. The amount of reinforcement can extend around the substantially entire circumference of the capillary wick. If a liquid storage portion is used, when the heating element is around the capillary wick, the amount of reinforcement may be closer to the liquid storage portion than the heating element. Alternatively, the amount of reinforcement may be further from the liquid storage portion than from the heating element.
[41] At least one of the amount or amounts of reinforcement may be trapped in the electrically heated aerosol generation system. This will provide additional structural support.

20/55 removable from the housing as a single component. This can be useful for refilling or replacing the liquid storage portion, for example.
[48] Preferably, the nozzle is replaceable. Having a wrap and a separate nozzle provides a number of advantages. First, if the replaceable nozzle contains the heater, the liquid storage portion and the wick, all elements that are potentially in contact with the liquid are changed when the nozzle is replaceable. There will be no cross contamination in the wrap between different nozzles, for example, those using different liquids. Also, if the nozzle is replaced at appropriate intervals, there is little chance that the heater will become clogged with liquid.

[52] The heating element preferably heats up when an electric current is passed through it. The heater can be for an electrically heated smoking system. The heater can be an electric heater for an electrically heated smoking system that has a capillary wick to hold a liquid. The heater may be arranged to heat the liquid in at least a portion of the capillary wick to form the aerosol.
[53] According to a third aspect of the present invention, there is also provided the use of a heater according to the second aspect of the present invention as a heater to heat an aerosol-forming substrate in an electrically heated aerosol generating system .
[54] The smoking system and the heater according to the present invention provide a number of advantages. The heater is cheap and easy to manufacture. Specifically, the heater is considerably simpler and easier to manufacture than prior art heaters which comprise a coil of wire arranged to surround a capillary wick. No welding or bonding of components can be required. The heater is robust.

In addition, as the heating element can be made of a sheet of electrically resistive material. The heating element can be manufactured very precisely. This is advantageous because even small changes in the heater structure (for example, the positioning and tensioning of the heater around the capillary wick) affects aerosol formation, specifically the particle size in the aerosol. This affects the smoking experience. Precise production ensures a consistent and repeatable smoking experience. In addition, it has generally been found that reducing the size of the aerosol forming chamber enhances the smoking experience by improving the aerosol forming process. However, the smaller aerosol forming chamber reduces tolerances on the size of the heater. The heater of the present invention can be produced very precisely, thereby solving this tolerance problem.
[55] The features described in relation to one aspect of the present invention may also be applicable to another aspect of the present invention.

[75] Figure 1 shows an example of a generation system
Petition 870190104476, of 10/16/2019, p. 28/68
24/55 aerosol. In figure 1 the system is a smoking system that has a liquid storage portion. The smoking system 100 of figure 1 is an electrically heated smoking system and comprises a housing 101 having a nozzle end 103 and a body end 105. At the body end, an electrical power source is provided in the form of a battery 107 and an electrical circuit in the form of a circuit 109 and a puff detection system 111. At the nozzle end, a liquid storage portion is provided in the form of a cartridge 113 containing a liquid 115, a capillary wick 117 and a heater 119. Note that the heater is only shown schematically in figure 1. One end of the capillary lock 117 extends into the cartridge 113 and the other end of the capillary lock 117 is surrounded by heater 119. The heater is connected to the electrical circuit via connections 121. Housing 101 also includes an air inlet 123, an air outlet 125 at the nozzle end and a aerosol 127.
[76] In use, the operation is as follows. The liquid 115 is transferred or carried by capillary action of the cartridge 113 from the end of the lock 117 which extends into the cartridge to the other end of the lock 117 which is surrounded by the heater 119. When a user aspirates over the device in the air outlet 125, ambient air is sucked through air inlet 123. In the arrangement shown in figure 1, the puff detection system 111 detects puff and activates heater 119. Battery 107 supplies a pulse of energy to the heater 118 to heat the wick end 117 surrounded by the heater. The liquid at this end of the wick 117 is vaporized by the heater 119 to create supersaturated steam. At the same time, the liquid being vaporized is replaced by an additional liquid that moves along the wick 117 by
Petition 870190104476, of 10/16/2019, p. 29/68
25/55 capillary action. (This is sometimes referred to as a pumping action). The supersaturated vapor created is mixed with and charged into the air flow of the air inlet 123. In the aerosol-forming chamber 127 the vapor condenses to form an inhalable aerosol, which is charged in the outward direction 125 and into the mouth of the user.
[77] In the mode shown in figure 1, circuit 109 and puff detection system 111 are preferably programmable. Circuit 109 and puff detection system 111 can be used to manage device operation. This, together with the physical design of the electrically heated smoking system, specifically the electric heating element, can help with the control of the particle size in the aerosol.
[78] The capillary wick can be made from a variety of porous or capillary materials and preferably has a known, predefined capillarity. Examples include materials based on ceramics or graphite in the form of sintered fibers or powders. Wicks of different porosities can be used to accommodate different physical properties of liquid such as density, viscosity, surface tension and vapor pressure. The wick should be adequate so that the required amount of liquid can be supplied to the heating element.
[79] Figure 1 shows an example of an aerosol generation system which can be used with the present invention. Many other examples are usable with the invention, however. For example, the system does not have to be a smoking system. For example, additional air intakes can be provided, for example, spaced circumferentially around the housing. For example, a puff detection system does not need to be provided. Instead the system could operate by manual operation, for example, the user operating a switch when a puff is made. For example, the
Petition 870190104476, of 10/16/2019, p. 30/68
The housing could comprise a separable casing and nozzle. For example, the total shape and size of the housing could be changed. For example, a different type of substrate, such as a solid substrate, could be provided. For example, the liquid cartridge can be omitted and the capillary wick could simply be pre-filled with liquid before use. Other variations are, of course, possible.
[80] A number of embodiments of the invention will now be described based on the example shown in figure 1. The components shown in figure 1 are not shown again, in order to simplify the drawings. In addition, the puff detection system 111 and connections 121 are not shown, again for simplicity. Note that all drawings are schematic in nature. Specifically, the components shown are not to scale or individually or in relation to each other.
[81] Figure 2 shows a first embodiment of a heater according to the invention. In the embodiment of figure 2, the heater 201 comprises an electrically positive support element 203 and an electrically negative support element 205. The support elements can also be referred to as connector blades. The heating element 207 extends between the connector blades 203, 205. One or more of the blades is integrally formed with the heating element. The term fully formed refers to both the blade and the heating element being made of a single piece of material.
[82] In the embodiment of figure 2, the heating element 207 comprises one or more elongated portions 208 (that is, portions which extend substantially along, or substantially parallel to the elongated geometric axis of the heater). The longitudinal portions 208 can be substantially parallel to the
Petition 870190104476, of 10/16/2019, p. 31/68
27/55 elongated support elements, 203, 205. The longitudinal portion or portions 208 of the heating element are joined by alternating transverse portions 210 of the heating element arranged at the ends of the longitudinal portion or portions of the heating element. The transverse portions 210 can connect to additional longitudinal portions 208 of the heating element. A transverse portion connects a longitudinal portion to one of the connector blades 203, 205. Another transverse portion also connects a longitudinal portion to the other of the connector blades 203, 205. The transverse portions can extend substantially perpendicular to the connector blades 203, 205. The transverse portions can extend substantially perpendicular to the longitudinal portions. The resulting structure is shaped like a square wave.
[83] The bottom of figure 2 shows a cross section along line 3-3. As can be seen from the bottom of figure 2, in this embodiment, the connector blades or support elements 203, 205 are formed together with the heating element 207 of a single piece of material. That is to say, the connector blades or support elements 203, 205 and the heating element 207 are integrally formed. The material part has a greater thickness in the region of the connector blades 203, 205 than in the region of the heating element 207.
[84] In figure 2, the length or height direction of the heater is shown at 222 and the thickness direction is shown at 224. The cross-sectional area of the heating element or support elements is measured perpendicular to the direction in which it is is extending. That is, for the support elements, the cross section is measured perpendicular to the direction 220, for the portions 208, the cross section is measured perpendicular to the direction 220, and for the portions 210, the cross section is measured perpendicular to the direction
Petition 870190104476, of 10/16/2019, p. 32/68
28/55
222.
[85] The longitudinal and transverse portions can be electrically joined together so that an electric current can flow when a potential difference is applied through the heating element. In addition, the longitudinal portions and the transverse portions can also be electrically connected to the connector blades or support elements. Then an electric current can flow in the heater when a potential difference is applied through the connector blades. The longitudinal portion or portions of the heating element may be longer than the transverse portions of the heating element (as shown). Alternatively, the longitudinal portion or portions of the heating element may be shorter than the transverse portions of the heating element.
[86] The embodiments of the invention may have a heating element with a square wave structure in which the height of the square wave structure is greater than the distance between the adjacent peaks or valleys of the square wave structure. In the drawings, the height of the square wave structure is approximately 5.5 times the distance between adjacent peaks and valleys. That is to say, the longitudinal portion or portions of the heating element have a length which is approximately 5.5 times the length of the transverse portions. This allows more of the heater to be in contact with the capillary wick and therefore leads to improved heating. Alternatively, the heating element may have a square wave structure in which the height of the square wave structure is equal to or less than the distance between the adjacent peaks or valleys of the square wave structure.
[87] Figure 3 shows the heater 201 of figure 2 mounted around a capillary wick 117. Figure 4 is a cross section
Petition 870190104476, of 10/16/2019, p. 33/68
29/55 along line 4-4 of figure 3. Figure 3 shows only the capillary wick 117 and the heater, plus the upper portion of the liquid cartridge 113. The remaining components of the smoking system are not shown. That is, figure 3 shows an enlarged view of box A in figure 1.
[88] As can be seen in figures 3 and 4, the connector blades 203, 205 are attached to the liquid cartridge 113, although these can be attached to another part of the device. In this embodiment, the connector blades are elongated and the longitudinal geometric axis of each connector blade extends substantially parallel to the longitudinal geometric axis of the elongated capillary wick. In this mode, the connector blades are attached to the same side of the capillary wick. In this mode, the connector blades are connected to the electrical circuit (not shown) through connections (also not shown).
[89] In this embodiment, the heating element 207 extends substantially around the entire capillary strand 117. In this embodiment, the heating element extends over only part of the length of the exposed portion of the capillary strand. As the elongated connector blades are relatively rigid compared to the relatively flexible heating element, when the connector blades are attached to the top of the liquid cartridge, the heating element is made to bend around the capillary wick.
[90] In an alternative embodiment, not shown in the drawings, the heating element can be rotated by approximately 90 ° in relation to the blades or support elements. That is, the longitudinal portions 208 can be substantially perpendicular to the elongated connector blades 203, 205. In this embodiment, the transverse portions can be substantially parallel to the connector blades 203, 205. The transverse portions can
Petition 870190104476, of 10/16/2019, p. 34/68
30/55 may still be substantially perpendicular to the longitudinal portions. This also applies to other embodiments of the invention. This arrangement has the advantage that the total length of the heating element in contact with the capillary wick is the same as in the modality shown in figures 2, 3 and 4, but, when the heater is curved or bent around the capillary wick, more of the heating element is curved or bent than in the modalities shown in figures 2, 3 and 4. This is because the elongated longitudinal portions of the heating element are curved around the capillary wick. Therefore, the heater in this mode can be more robust and less likely to collapse or be deformed when mounted around the capillary wick.
[91] The heating element in figure 2 comprises an electrically resistive material. The heating element comprises a sheet of material, preferably metallic, formed as desired, then wrapped around the capillary wick. The sheet metal can be cut by any suitable laser, chemical or electrical process. Once cut, the metal sheet can be rolled or folded around the capillary wick. The sheet metal can be cut to any suitable shape and, as will be discussed below, it can include portions that have different shapes and cross-sectional areas to assist with heat distribution. Heat distribution affects aerosol formation, specifically the size of aerosol particles. This affects the smoking experience for the user.
[92] The production of the heating element by cutting from a sheet of material, rather than, for example, as a coil, can simplify manufacturing. In addition, it allows the shape of the heater to be more precisely defined, which can improve the consistency of the aerosol. In addition, the heating element can
Petition 870190104476, of 10/16/2019, p. 35/68
31/55 to be more robust. The heat distribution can also be improved and the contact between the heating element and the capillary wick can be improved.
[93] A number of variations in the heater are possible. The shape, height and thickness of the connector blades can be variable. In addition, the area and cross-sectional shape of the heating element can be varied and this will be discussed below. The height of the heating element compared to the length of the exposed portion of the capillary wick and the height of the connector blades can be varied. The heating element can comprise any suitable electrically resistive material. The material can have a variety of thicknesses. In addition, the heater may have connector blades which have a different thickness than the thickness of the heating element. As already discussed, this is shown at the bottom of figure 2. In this embodiment, the blades or support elements and the heating element are formed of a material which is thicker in the blade part of the heater than in the element part. heater heating. This has the advantage that the blades or support elements are even more rigid. As shown at the bottom of figure 2, the cross section of the material from which the heater is made is substantially in the form of dog bone. Other ways are possible. The blades can be twice as thick as the central portion of the heating element. Such a heater can be produced by chemical attack. In this case, a sheet of material, such as a metal, of approximately constant thickness can be attacked or etched with chemicals in order to produce a sheet of material or a heater with variable thickness. The material can have a variety of Young modules, that is, elasticity. These properties in the material will affect its assembly and the resulting structure. The assembly of the
Petition 870190104476, of 10/16/2019, p. 36/68
32/55 heater around the capillary wick is discussed below with respect to figures 17, 18 and 19.
[94] Figure 5 shows a second embodiment of a heater according to the invention. In the embodiment of figure 5, heater 501 comprises an electrically positive connector blade 503 and an electrically negative connector blade 505. The heating element 507 extends between the blades 503, 505. In the embodiment of figure 5, the heating element 507 comprises portions 508 of heating element which extends longitudinally (that is, portions which extend substantially parallel to the connector blades 503, 505 or to the longitudinal geometric axis of the heater), joined by alternating transverse portions 510 positioned at each end of the heating elements longitudinal heating (that is to say, the portions which extend substantially perpendicular to the connector blades 503, 505 or the geometric axis of the system). Similar to the modality in figure 2, the resulting structure has the shape of a square wave. The specific shape of the square wave, including its orientation, and its height in relation to the distance between adjacent peaks and valleys, can be varied as described in relation to figure 2.
[95] However, in the embodiment of figure 5, the 508 portions of the heating element that extends longitudinally are wider so that these portions have a greater cross-sectional area, at least in some places, than other portions of the element of heating. The longitudinally extending portions of the heating element 508 have two convex sides that form a lens shape. That is to say, the longitudinal portions 508 of the heating element are wider in the middle, than at each end of the longitudinal portions of the heating element.
Petition 870190104476, of 10/16/2019, p. 37/68
33/55 [96] The variation in shape affects the resistive heating produced by the heating element and thus the heat distribution around the capillary wick. Specifically, the Joule effect means that, for a given electrical current, the callus produced is proportional to the resistance. The resistance, of course, depends on the shape of the resistor, including its cross-sectional area. This means that the cross-sectional shape of the heating element can be used to control the heat distribution. Specifically, the inventors of the present invention have noted that sometimes with a heating element that has a constant cross section over its length, hot spots can be formed in the middle or at the ends of the heating element. This can result in overheating of the capillary wick at certain points. The provision of a portion or portions of the heating element that have a greater cross-sectional area reduces the strength of these portions, thereby reducing Joule heating. This reduces the likelihood of hot spots forming and provides a more uniform heat distribution. In one embodiment, the largest cross-sectional area of the heating element can be approximately twice the smallest cross-sectional area of the heating element. That is, the middle portion 511 of the longitudinally extending portions 508 of the heating element.
[97] As in the previous modality, at least one of the blades is integrally formed with the heating element. This means that both the blade and the heating element can be made of a single piece of material.
[98] The heater in figure 5 is mounted around a capillary wick in the same way as shown in figures 3 and 4. The aspects of this assembly are described in relation to figures 3 and 4 and will not be repeated. The heating element in figure 5 comprises a
Petition 870190104476, of 10/16/2019, p. 38/68
34/55 electrically resistive material and the various properties of the heater and the heating element are described in relation to the figures
2, 3 and 4 and will not be repeated. The assembly of the heater around the capillary wick is discussed below with respect to figures 17, 18 and
19.
[99] Figure 6 shows a third modality of the heater according to the invention. In the embodiment of figure 6, heater 601 comprises an electrically positive connector blade 603 and an electrically negative connector blade 605. The heating element 607 extends between the blades 603, 605. One or both blades are integrally formed with the element of heating. In the embodiment of figure 6, the heating element 607 comprises elongated portions 608 of heating element which (that is to say, portions which extend substantially parallel to the connector blades 603, 605 or substantially parallel to the elongated geometric axis of the heater). The longitudinal portions of the heating element can be joined by alternating transverse portions 610 of the heating element positioned at the ends of the longitudinal portions of the heating element. The transverse portions can extend substantially perpendicular to the longitudinal portions of the heating element. In figure 6, the transverse portions 610 comprise semicircular portions. In figure 6, the semicircular portions have their curved surface facing away from the middle portion 611 of the longitudinal portion 608 of the heating element, although this need not be the case. As in the previous embodiment, the structure of the heating element is substantially that of a square wave. The specific shape of the square wave, including its orientation, and its height in relation to the distance between adjacent peaks and valleys, can be varied as described in relation to figure 2.
Petition 870190104476, of 10/16/2019, p. 39/68
35/55 [100] Similar to the modality shown in figure 5, the variation in shape affects the resistive heating produced by the heating element and thus the heat distribution around the capillary wick. Specifically, the provision of a portion or portions of the heating element that have a greater cross-sectional area reduces the likelihood of hot spots and provides a more uniform heat distribution. In one embodiment, the largest cross-sectional area of the heating element can be approximately twice the smallest cross-sectional area of the heating element.
[101] The heater in figure 6 is mounted around a capillary wick in the same way as shown in figures 3 and 4. The aspects of this assembly are described in relation to figures 3 and 4 and will not be repeated. The heating element in figure 6 comprises an electrically resistive material and the various properties of the heater and the heating element are described in relation to figures 2, 3 and 4 and will not be repeated. The assembly of the heater around the capillary wick is discussed below with respect to figures 17, 18 and 19.
[102] Figure 7 shows a fourth embodiment of a heater according to the invention. In the embodiment of figure 7, heater 701 comprises an electrically positive connector blade 703 and an electrically negative connector blade 705. The heating element 707 extends between the blades 703, 705. In the embodiment of figure 7, the heating element 707 has the shape of a triangular wave. That is to say, the heating element 707 comprises elongated portions 708 which extend diagonally in a first direction of blade 705 in the direction of blade 703 and elongated portions 710 which extend diagonally in a second direction of blade 705 in the direction of blade 703. The portions 708 and the portions 710 are connected alternately, so as to form a shape of
Petition 870190104476, of 10/16/2019, p. 40/68
36/55 substantially triangular wave. Specifically, the heating element 707 does not include portions which are substantially parallel to the connector blades or substantially perpendicular to the connector blades. All portions of the heating element are inclined with respect to the connector blades.
[103] In the embodiment shown in figure 7, the angle between the elongated portions 708, 710 and the connector blades 703, 705 is approximately 15 °. In addition, the angle between the elongated portions 708, 710 of the heating element is approximately 30 °. (Note that these angles are not shown precisely in figure 7). These angles have the advantage that more of the elongated portions 708, 710 are in contact with the wick than would be the case if the angle between the blade and the elongated portion were greater, for example, 80 °. In this mode, the triangular waveform has a peak to valley distance which is approximately twice the distance between adjacent peaks or valleys of the wave.
[104] The heater in figure 7 is mounted around the capillary wick in the same way as shown in figures 3 and 4. The aspects of this assembly are described in relation to figures 3 and 4 and will not be repeated. In addition to adjusting the heat distribution around the capillary wick, the triangular shape of the heating element ensures good contact between the heating element 707 and the capillary 117 as the device is assembled. Specifically, the inventors have found that the triangular shape of the heating element makes it easier to wrap around the wick, since it is less rigid than heating elements that have other shapes. The assembly will be further discussed with respect to figures 17, 18 and 19.
[105] The heating element in figure 6 comprises an electrically resistive material and the various properties of the heater
Petition 870190104476, of 10/16/2019, p. 41/68
37/55 and the heating element are described in relation to figures 2, 3 and 4 and will not be repeated. In addition, for the embodiment of figure 7, the elongated portions that extend diagonally can extend at any appropriate angle. The elongated portions 708 do not need to extend in the same, but opposite, angle as the elongated portions 710.
[106] Figure 8 shows a fifth mode of the heater according to the invention. In the embodiment of figure 8, the heater 801 comprises an electrically positive connector blade 803 and an electrically negative connector blade 805. The heating element 807 extends between the blades 803, 805. In the embodiment of figure 8, the heating element 807 it has the shape of a substantially triangular waveform, similar to that in the modality shown in figure 7.
[107] In the mode shown in figure 8, the angle between the elongated portions and the connector blades is approximately 15 °. Furthermore, the angle between the elongated portions of the heating element is approximately 30 °. (Again, note that these angles are not shown precisely in figure 8). These angles have the advantage that more of the elongated portions are in contact with the wick than would be the case if the angle between the blade and the elongated portion were greater, for example, 80 °. In this mode, the triangular waveform has a peak to valley distance which is approximately twice the distance between adjacent peaks or valleys of the wave.
[108] However, in the modality shown in figure 8, the peaks and valleys of the triangular wave are not pointed, as in the modality shown in figure 7. Instead, the peaks and valleys are curved or rounded peaks and valleys, that is to say , the heating element 807 is substantially in the shape of a sine wave. The heating element
Petition 870190104476, of 10/16/2019, p. 42/68
The cement has a shape similar to the heating element of figure 7, but the portions that extend diagonally are connected by curves. Specifically, like the embodiment of figure 7, the heating element 807 does not include large portions which are substantially parallel to the connector blades or substantially perpendicular to the connector blades. Other than in curved portions, all portions of the heating element are inclined in relation to the connector blades.
[109] The heater in figure 8 is mounted around a capillary wick in the same way as shown in figures 3 and 4. The aspects of this assembly are described in relation to figures 3 and 4 and will not be repeated. In addition to adjusting the heat distribution around the capillary wick, the heating element waveform ensures good contact between heating element 807 and capillary 117 as the device is assembled. Specifically, the inventors have found that the heating element waveform makes it easier to wrap around the wick, as it is less rigid than other shaped heating elements. The assembly will be further discussed with respect to figures 17, 18 and
19.
[110] The heating element in figure 8 comprises an electrically resistive material and the various properties of the heater and the heating element are described in relation to figures 2, 3 and 4 and will not be repeated. In addition, for the embodiment of figure 8, the elongated portions that extend diagonally can extend at any appropriate angle. The heating element does not need to have the exact sinusoidal shape, but it can have any suitable curved shape.
[111] Figure 9 shows a sixth embodiment of a heater according to the invention. In the modality of figure 9, the heater
Petition 870190104476, of 10/16/2019, p. 43/68
39/55
901 comprises an electrically positive connector blade 903 and an electrically negative connector blade 905. Heating element 907 extends between connector blades 903, 905. One or more of the blades is integrally formed with the heating element. In the embodiment of figure 9, the heating element 907 comprises one or more elongated longitudinal portions 908 (that is, portions which extend substantially along or substantially parallel to the elongated geometric axis of the heater). The longitudinal portions 908 can be substantially parallel to the connector blades 903, 905. The longitudinal portion or portions of the heating element are joined by alternating transverse portions 910 of the heating element arranged at the ends of the longitudinal portions of the heating element. The transverse portions can be joined to or connected to the additional longitudinal portions of the heating element. A transverse portion connects a longitudinal portion on the connector blade. Another transverse portion connects a longitudinal portion to the other connector blade. The transverse portions can extend substantially perpendicular to the connector blades 903, 905. Similar to the modalities of figures 2, 5 and 6, the resulting structure is in the form of a square wave. The specific shape of the square wave, including its orientation, and its height in relation to the distance between adjacent peaks and valleys, can be varied as described in relation to the figure
2.
[112] However, in the embodiment of figure 9, the heater still includes two reinforcement portions 909 adjacent to the connector blades 903 and 905. Each reinforcement portion 909 comprises several uprights 911 that connect the connector blade with the portion extending longitudinally 908 closest to the heating element. One or more of the 911 amounts may be substantially perpendicular
Petition 870190104476, of 10/16/2019, p. 44/68
40/55 homes to the longitudinal portion of the heating element. One or more of the uprights 911 can be substantially perpendicular to one or more of the connector blades 903, 905. An upright may be positioned approximately halfway along the longitudinal portion closest to the heating element. An additional amount may be positioned at one or both ends of the longitudinal portion of the heating element. One or more of the connector blades may comprise a reinforcement portion 909.
[113] If the reinforcement portion 909 is electrically conductive, this results in several electrical connection paths from each connector blade to the longitudinally extending portion 908 closest to heating element 907. However, the electrical current predominantly does not flow along the reinforcement portion, because this portion has a higher strength than the shorter transverse portion 913 of the heating element, due to its greater length. Therefore, the reinforcement portion 909 does not heat as much as the rest of the heater. Otherwise, if the reinforcement portion is not electrically conductive, only a single electrical connection path can be provided.
[114] Reinforcement portions 909 can be made of a material that is more rigid than heating element 907, but more flexible than connector blades 903, 905. Preferably, reinforcement portions 909 are made of the same material than the rest of the heater. Preferably, one or more of the reinforcement portions can be integrally formed with the heating element. The cross-sectional dimension of the reinforcement portion may be larger than the cross-sectional dimension of the heating element, in order to further reinforce the reinforcement portion.
[115] In another embodiment, not shown in the drawings, the reinforcement portion may comprise a sheet of material, which is
Petition 870190104476, of 10/16/2019, p. 45/68
41/55 preferably the same material as the heating element or the connector blades. In this case, the reinforcement portion joins the connector blade and the longitudinal portion of the heating element closest to the connector blade with a sheet material of substantially rectangular or square shape. Referring to figure 9, this would comprise a sheet of material extending from the uppermost or lowermost amount 911 to the middle amount 911 or a sheet of material extending from the transverse portion 913 to the middle amount 911 or both. These filled reinforcement portions can also be integrally formed with the heating element.
[116] The heater in figure 9 is mounted around a capillary wick in the same way as shown in figures 3 and 4. The aspects of this assembly are described in relation to figures 3 and 4 and will not be repeated. Depending on the stiffness of the reinforcement portions 909, these portions may bend less than or the same amount as the heating element 907. The reinforcement portions reinforce the structure of the heater. The reinforcement portions also ensure good contact of the heating element and the capillary wick and allow the heating element to fit around the capillary wick when the device is assembled. This is due to a spring effect when the heater is folded into a substantially tubular shape shown in figures 3 and 4. The folded metal ensures good contact of the heating element on the capillary wick, the assembly will be further described in relation to figures 17, 18 and 19.
[117] The heating element in figure 9 comprises an electrically resistive material and the various properties of the heater and the heating element are described in relation to figures 2, 3 and 4 and will not be repeated. In addition, the shape and size of the reinforcement portions can be varied. For example, the reinforcement portions may comprise a solid portion of material, for example
Petition 870190104476, of 10/16/2019, p. 46/68
42/55 plo, like a flag or flange that extends from the connector blade, instead of individual uprights. Only a single portion of reinforcement can be provided. Or more than one reinforcement portion can be provided adjacent to each connector blade. The reinforcement portions can comprise any suitable material. The material is preferably more rigid than the material of the heating element in order to reinforce the structure of the heater. The reinforcement portions do not have to have the same structure or be made of the same material. Preferably, however, the reinforcement portions are made of the same material as the rest of the heater. Preferably one or more of the reinforcement portions are integrally formed with the heating element.
[118] The reinforcement portions provided in the embodiment of figure 9 can be provided with any other form of suitable heating element, including the shapes shown in figures 2, 5, 6, 7 and 8.
[119] Figure 10 shows a seventh modality of the heater according to the invention. In the embodiment of figure 10, heater 1001 comprises an electrically positive connector blade 1003 and an electrically negative connector blade 1005. Heating element 1007 extends between connector blades 1003, 1005. One or more of the blades is integrally formed with the heating element. In the embodiment of figure 10, heating element 1007 comprises portions 1008 of a heating element that extends longitudinally (i.e., portions which extend substantially along or substantially parallel to the elongated geometric axis of the heater). The longitudinal portions 1008 of the heating element are joined by alternating transverse portions 1010 of the heating element arranged at the ends of the longitudinal portions of the heating element
Petition 870190104476, of 10/16/2019, p. 47/68
43/55 heating. The transverse portions can extend substantially perpendicular to the connector blades 1003, 1005. Similar to the modalities of figures 2, 5, 6 and 9, the resulting structure is in the form of a square wave. The specific shape of the square wave, including its orientation, and its height in relation to the distance between adjacent peaks and valleys, can be varied as described in relation to figure 2.
[120] As in the embodiment of figure 9, the heater also includes two reinforcement portions 1009 adjacent to connector blades 1003 and 1005. The properties of these reinforcement portions 1009 are similar to those of reinforcement portions 909 in figure 9, and will not be repeated.
[121] The heater 1001 further comprises an additional reinforcement portion 1015 between the two connector blades, in the center of the heating element in this embodiment. The reinforcement portion 1015 can be very similar in structure to the reinforcement portions 1009. For example, the reinforcement portion 1015 can comprise several uprights connecting the adjacent longitudinally extending portions 1008. If the reinforcement portion 1015 is electrically conductive, this results in several electrical connection paths between the two vertically extending adjacent portions 1008. However, the electric current predominantly does not flow along the reinforcement portion 1015, because this portion has a higher resistance than the shorter transverse portion 1017 of the heating element, due to its greater length. Therefore, the reinforcement portion 1015 does not heat as much as the rest of the heater. If the reinforcement portion 1015 is not electrically conductive, only a single electrical connection path can be provided. More than a central reinforcement portion 1015 can be provided if desired.
[122] Reinforcement portions 1009, 1015 can be made of a material that is more rigid than heating element 1007,
Petition 870190104476, of 10/16/2019, p. 48/68
44/55 but more flexible than connector blades 1003, 1005. However, reinforcement portions 1009, 1015 are preferably made of the same material as the rest of the heater. Preferably, one or more of the reinforcement portions can be integrally formed with the heating element. The cross-sectional dimension of the reinforcement portion may be larger than the cross-sectional dimension of the heating element, in order to further reinforce the reinforcement portion.
[123] As described with reference to figure 9, one or more of the reinforcement portions may alternatively comprise a sheet of material.
[124] The heater in figure 10 is mounted around a capillary wick in the same way as shown in figures 3 and 4. The aspects of this assembly are described in relation to figures 3 and 4 and will not be repeated. Depending on the stiffness of the reinforcement portions 1009, 1015, these portions may bend less than or the same amount as the heating element 1007. The reinforcement portions reinforce the structure of the heater. The reinforcement portions also ensure good contact of the heating element and the capillary wick and allow the heating element to fit around the capillary wick when the device is assembled. This is due to a spring effect of the folded sheet metal, as previously described. This will be further discussed in relation to figures 17, 18 and 19.
[125] The heating element in figure 10 comprises an electrically resistive material and the various properties of the heater and the heating element are described in relation to figures 2, 3 and 4 and will not be repeated.
[126] In addition, the shape, size, structure and material of the reinforcement portions can be varied as described in figure 9. A
Petition 870190104476, of 10/16/2019, p. 49/68
45/55 reinforcement portion of the heating element may be provided together or separately from the reinforcement portion or portions adjacent to the connector blades.
[127] The reinforcement portions provided in the embodiment of figure 10 can be provided with any other form of suitable heating element, including the shapes shown in figures 2, 5, 6, 7 and 8.
[128] Figure 11 shows an eighth modality of a heater according to the invention. In the embodiment of figure 11, heater 1101 comprises an electrically positive connector blade 1103 and an electrically negative connector blade 1105. The heating element 1107 extends between connector blades 1103, 1105. One or more of the blades is integrally formed with the heating element. In the embodiment of figure 11, the heating element 1107 comprises portions of a heating element which extends longitudinally (that is, portions which extend substantially along or substantially parallel to the elongated geometric axis of the heater). The longitudinal portions can be parallel to the elongated connector blades 1103, 1105. The longitudinal portions of the heating element are joined by alternating transverse portions of the heating element arranged at the ends of the longitudinal portions of the heater. The transverse portions can extend substantially perpendicular to the connector blades 1103, 1105. The resulting structure is in the form of a square wave. The specific shape of the square wave, including its orientation, and its height in relation to the distance between adjacent peaks and valleys, can be varied as described in relation to figure 2.
[129] In the embodiment of figure 11, the heater also includes a lower amount of reinforcement 1113 and an amount of higher reinforcement

46/55
1115. In this embodiment, the lower reinforcement riser 1113 is an extension of the positive connector blade 1103. The lower reinforcement riser 1113 extends from the positive connector blade 1103 in a perpendicular direction at a height over the lower positive connector blade 1103. than the heating element 1107. That is to say, when the heater is mounted around a capillary wick, the lower reinforcement amount 1113 will be closer to the liquid cartridge 113 than the heater 1107. The lower reinforcement amount 1113 extends towards the 1105 negative connector blade but does not make contact with it. Similarly, the upper reinforcement riser 1115 is an extension of the negative connector blade 1105. The upper reinforcement riser 1115 extends from the negative connector blade 1105 in a perpendicular direction at a height over the negative connector blade 1105 which is higher than than the heating element 1107. That is to say, when the heater is mounted around a capillary wick, the upper reinforcement amount 1115 will be further away from the liquid cartridge 113 than the heater 1107. The upper reinforcement amount 1115 extends towards the positive connector blade 1103 but does not make contact with it. The negative connector blade could alternatively be connected to the lower reinforcement. The positive connector blade could alternatively be connected to the upper reinforcement. In addition, only one of the upper and lower reinforcement amounts needs to be provided.
[130] Preferably, the bottom reinforcement amount is made of the same material as the connector blade on which it is attached, the positive connector blade 1103 in figure 11. Similarly, preferably, the upper reinforcement amount is made of the same material as the connector blade on which it is attached, which is the negative connector blade 1105 in figure 11. Preferably, the lower amount
Petition 870190104476, of 10/16/2019, p. 51/68
47/55 or the upper amount or both are integrally formed with the heating element.
[131] Figure 12 shows the heater 1101 of figure 11 mounted around a capillary wick 117. Figure 13 is a cross section along line 13-13 of figure 12. Figure 12 shows only capillary wick 117 and the heater, plus the top portion of the liquid cartridge 113. The remaining components of the smoking system are not shown. That is to say, figure 12 shows an enlarged view of box A in figure 1. Figures 12 and 13 are similar to figures 3 and 4, and the assembly aspects that are described in relation to figures 3 and 4 will not be repeated. Referring to figures 12 and 13, the lower reinforcement amount 1113 extends substantially around the entire capillary wick 117. The lower reinforcement amount 1113 is closer to the liquid cartridge 113 than the heating element 1107. The reinforcement amount upper 1115 extends substantially around the entire capillary wick 117. The upper reinforcement amount 1115 is further away from the liquid cartridge 113 than the heating element 1107.
[132] Reinforcement uprights 1113, 1115 reinforce the heater structure. The reinforcement uprights 1113, 1115 preferably comprise the same material as the connector blades 1103, 1105, which is more rigid than the material of the heating element 1107. The reinforcement uprights also ensure good contact of the heating element and the capillary wick and allow the heating element to mount adjusted around the capillary wick when the device is assembled. The assembly will be further described with reference to figures 17, 18 and 19. In addition, the reinforcement uprights 1113, 1115 provide support for the capillary wick 117 when the device is assembled. If the heater comprises only a relatively flexible material, the capillary wick may have
Petition 870190104476, of 10/16/2019, p. 52/68
48/55 a tendency to fall or tip out towards the top. The relatively rigid upper and lower amounts of reinforcement reduce this likelihood.
[133] The heating element in figures 11, 12 and 13 comprises an electrically resistive material and the various properties of the heater and the heating element are described in relation to figures 2, 3 and 4 and will not be repeated. In addition, the shape and size of the upper and lower reinforcement amounts can be varied. The reinforcement amounts can comprise any suitable material. Only one of the upper and lower reinforcement amounts needs to be provided. The reinforcement portions shown in figures 9 and 10 can also be provided together with the upper and lower reinforcement amounts.
[134] The amounts of reinforcement provided in the form of figures 11, 12 and 13 can be provided with any other form of suitable heating element, including the shapes shown in figures 2, 5, 6, 7 and 8.
[135] Figure 14 shows a ninth modality of a heater according to the invention. In the embodiment of figure 14, heater 1401 comprises an electrically positive connector blade 1403 and an electrically negative connector blade 1405. Heating element 1407 extends between connector blades 1403, 1405. One or more of the blades can be integrally formed with the heating element. In the embodiment of figure 14, heating element 1407 comprises portions of a heating element that extends longitudinally (i.e., portions which extend substantially along or substantially parallel to the elongated geometric axis of the heater). The longitudinal portions can be parallel to the elongated connector blades 1103, 1105. The longitudinal portions can be parallel to the blades
Petition 870190104476, of 10/16/2019, p. 53/68
49/55 of connector 1403, 1405. The longitudinal portions of the heating element are joined by alternating transverse portions of the heating element arranged at the ends of the longitudinal portions of the heater. The transverse portions can extend substantially perpendicular to the connector blades 1403, 1405. The resulting structure is in the form of a square wave. The specific shape of the square wave, including its orientation, and its height in relation to the distance between adjacent peaks and valleys, can be varied as described in relation to figure 2.
[136] In the embodiment of figure 14, the heater also includes two reinforcement portions 1409 adjacent to connector blades 1403 and 1405, as in figure 9. The properties of these reinforcement portions 1409 are similar to those of reinforcement portions 909 in figure 9 , and will not be repeated.
[137] In figure 14, the heater also includes two upper reinforcement posts 1408 and 1410 and two lower reinforcement posts 1414 and 1416. In this embodiment, the lower reinforcement post 1414 is an extension of the positive connector blade 1403. The amount lower reinforcement 1414 extends from the positive connector blade 1403 in a perpendicular direction at a height over the positive connector blade 1403 lower than the heating element 1407. Similarly, the lower reinforcement amount 1416 is an extension of the connector blade negative 1405. The lower reinforcement amount 1416 extends from the negative connector blade 1405 in a perpendicular direction at a height over the negative connector blade 1405 lower than the heating element 1407. That is, when the heater is mounted to the around a capillary wick, the lower reinforcement amounts 1414, 1416 will be closer to the liquid cartridge 113 than the heating 1407. These will also be at approximately the same time in relation to
Petition 870190104476, of 10/16/2019, p. 54/68
50/55 tion to the other. The lower reinforcement uprights 1414, 1416 extend towards each other, but do not make contact.
[138] Similarly, in this embodiment, the upper reinforcement riser 1408 is an extension of the positive connector blade 1403. The upper reinforcement riser extends from the positive connector blade 1403 in a perpendicular direction at a height over the positive connector blade 1403. higher than the heating element 1407. Similarly, the upper reinforcement amount 1410 is an extension of the negative connector blade 1405. The upper reinforcement amount 1410 extends from the negative connector blade 1405 in a perpendicular direction at a height over the negative connector blade 1405 higher than heating element 1407. That is to say, when the heater is mounted around a capillary wick, the upper reinforcement uprights 1408, 1410 will be further away from the liquid cartridge 113 than the heating element 1407. These will also be at approximately the same height in relation to each other. The upper reinforcement uprights 1408, 1410 extend towards each other, but do not make contact.
[139] The lower two amounts of reinforcement need not be at the same height. The top two reinforcement uprights need not be at the same height. In addition, only one of the two upper and lower reinforcement amounts needs to be provided. Preferably, the lower reinforcement posts are made of the same material as the connector blades to which they are attached. Similarly, preferably, the upper reinforcement uprights are made of the same material as the connector blades to which they are attached. Preferably, one or both of the lower uprights or one or both of the upper uprights or both are integrally formed with the heating element.
[140] Figure 15 shows the heater 1401 in figure 14 mounted
Petition 870190104476, of 10/16/2019, p. 55/68
51/55 around a capillary wick 117. Figure 16 is a cross section along line 16-16 in figure 15. Figure 15 shows only capillary wick 117 and the heater, plus the upper portion of the liquid cartridge 113. The remaining components of the smoking system are not shown. That is, figure 15 shows an enlarged view of box A in figure 1. In addition, the liquid cartridge 113 in figure 15 comprises an upper portion 114 at the top of capillary wick 117. The upper portion 114 may be an extension of part of the liquid cartridge 113. That is, they can be formed from the same piece of material.
[141] Figures 15 and 15 are similar to figures 3 and 4, and the aspects of the assembly that are described in relation to figures 3 and 4 will not be repeated. As can be seen in Figures 15 and 16, the connector blades 1403, 1405 are attached to the top of the liquid cartridge 113 and to the bottom of the upper portion 114 of the liquid cartridge. However, these could be attached to another part of the device or only to one of the liquid cartridge 113 and the upper portion 114. In addition, the lower reinforcement amounts 1414, 1416 can extend substantially around the entire capillary wick 117. In this embodiment, the lower reinforcement struts 1414, 1416 are trapped within a substantially circular groove (not shown) in the liquid cartridge 113. The upper reinforcement struts 1408, 1410 extend substantially around the entire capillary strand 117. In this embodiment , the upper reinforcement uprights 1408, 1410 are trapped within a substantially circular groove (not shown) in the upper portion 114 of the liquid cartridge.
[142] Reinforcement uprights 1408, 1410, 1414, 1416 reinforce the heater structure. Reinforcement uprights 1408, 1410, 1414, 1416 may comprise the same material as connector blades 1403, 1405, which is more rigid than the material of the element
Petition 870190104476, of 10/16/2019, p. 56/68
52/55 heating 1407. In addition, securing the reinforcement uprights 1414, 1416 within a groove of the liquid cartridge 113 provides additional structural integrity. In addition, securing the reinforcement uprights 1408, 1410 within a groove in the upper portion 114 of the liquid cartridge provides additional structural integrity. One or more of the reinforcement uprights can be integrally formed with the heating element.
[143] The reinforcement uprights also ensure good contact of the heating element and the capillary wick and allow the heating element to mount adjusted around the capillary wick when the device is mounted. This will be further discussed in relation to figures 17, 18 and 19. In addition, the reinforcement amounts, especially in conjunction with the upper portion 114 of the liquid cartridge and the grooves in the liquid cartridge 113 and the upper portion 114 of the liquid cartridge. liquid provide support for the capillary wick 117 when the device is assembled. If the heater comprises only a relatively flexible material, the capillary wick may have a tendency to fall or tip out towards the top. The relatively rigid upper and lower reinforcement uprights stuck in the grooves reduce this likelihood.
[144] The heating element in figures 14, 15 and 16 comprises an electrically resistive material and the various properties of the heater and the heating element are described in relation to figures 2, 3 and 4 and will not be repeated. In addition, the shape and size of the upper and lower reinforcement amounts can be varied. For example, the two lower reinforcement uprights may not be the same length or shape. For example, the top two reinforcement uprights may not be the same length or shape. The reinforcement amounts can comprise any suitable material. Only one of the upper and lower reinforcement
Petition 870190104476, of 10/16/2019, p. 57/68
53/55 needs to be provided. The reinforcement portions shown in figures 9 and 10 can also be provided together with the upper and lower reinforcement amounts. The reinforcement posts do not need to be slotted on the liquid cartridge, although this improves structural integrity. The shape of the grooves can be used to bend the heating element to the shape around the capillary wick as desired.
[145] The amounts of reinforcement provided in the form of figures 14, 15, and 16 can be provided with any other form of suitable heating element, including the shapes shown in figures 2, 5, 6, 7 and 8.
[146] Note that a number of different modalities have been described, and the aspects described in relation to one modality can often be applicable to another modality.
[147] Figures 17, 18 and 19 show the steps involved in assembling a heater around a capillary wick according to one embodiment of the invention. The heater can take the shape shown in any of figures 2 to 16.
[148] Referring to figure 17, first the heating element 1707 is curved around bringing the connector blades 1703, 1705 towards each other, preferably using a folding tool. In this case, the folding tool forms the heater in the form of a cylinder with a substantially round cross section. Once the heater is formed, the wick 117 can be inserted into it as shown in figures 18 and 19. The spring effect of the folded metal ensures a good contact of the heater on the wick. The diameter of the folded heater can be slightly smaller than the diameter of the wick, to ensure good contact. For example, the folded heater can have a diameter of approximately 1.9 mm, for a wick diameter of
Petition 870190104476, of 10/16/2019, p. 58/68
54/55 approximately 2.0 mm.
[149] In this mode, the elasticity of the heating element ensures that the heater is tensioned to spring inward in the direction of the lock when the heater is folded away in the direction of the arrows shown in figure 18. Referring to figure 18, the heating element The heating element is secured around the capillary wick 117 by moving the open heating element in the direction of the wick 117 as shown by the arrow. The heating element is then released, and as shown in figure 19, blades 1703, 1705 are attached to one side of the capillary wick, and the heating element is positioned closely around the capillary wick.
[150] As already mentioned, the heating element has a specific elasticity, which is affected by the thickness of the sheet of material used for the heating element, the shape in which the plate was cut and the elasticity (that is, the modulus Young) of the plate. Specifically, the heating elements formed triangular and sinusoidal have been found to be specifically advantageous for assembly. In addition, if the heater includes the reinforcement portions, this will also affect the overall elasticity of the heater. When the connector blades are attached, this elasticity ensures an adjusted fit around the capillary wick. This ensures consistency in the heat distribution and thereby aerosol formation. This ensures the repeatability of the smoking experience.
[151] Figures 20 and 21 show the temperature distribution of two heaters according to the modalities of the invention.
[152] The heater in figure 20 is similar to the modality shown in figure 9, except that the transverse portions of the heating element take the form of a semicircular arc. The heater shown in figure 20 also includes an upper reinforcement amount and a lower reinforcement amount, similar to the modality shown in the figure
Petition 870190104476, of 10/16/2019, p. 59/68
55/55
11. Both the upper and lower amounts are, however, optional; none, one or both amounts of reinforcement can be included.
[153] The temperature scale on the right side of figure 20 is a linear scale with the darker portions of the scale being cooler than the lighter portions of the scale. It can be seen that the warmest (lightest) portion of the heater is approximately five times warmer than the coldest (darkest) portion of the heater. The heater predominantly heats in the heating element portion of the heater. The reinforcement portions, and the upper reinforcement amount and the lower reinforcement amount, as well as the connector blades, all remain cooler than the heating element portion of the heater.
[154] The heater of figure 21 is similar to the embodiment shown in figure 20, except that the central portion of the heater, that is, the heater portion substantially equidistant from the connector blades, comprises a reinforcement portion. The reinforcement portion is substantially rectangular in shape, with a semicircular portion at one end. The temperature scale on the right side of figure 21 is a linear scale with the darker portions of the scale being cooler than the lighter portions of the scale. It can be seen that the warmest (lightest) portion of the heater is approximately five times warmer than the coldest (darkest) portion of the heater. The heater predominantly heats in the heating element portion of the heater. The reinforcement portion, and the upper reinforcement amount and the lower reinforcement amount, as well as the connector blades, all remain cooler than the heater heating element portion.
