    DISTRIBUTOR OF VOLATILE MATERIAL AND METHOD OF EMISSION OF A VOLATILE MATERIAL
    CROSS REFERENCE TO RELATED APPLICATIONS [001] This application claims the benefits of the U.S. provisional patent application of Jaworski et al, No. 61 / 680,110, filed on August 6, 2012, and entitled Volatile Material Dispenser.
    FUNDAMENTALS
    FIELD OF DESCRIPTION [002] The present invention generally relates to heaters for use in volatile material dispensers, and, more particularly, to volatile material dispensers having heaters for volatilizing a volatile material.
    BACKGROUND DESCRIPTION [003] Various volatile material distributors are known in the prior art and generally include a housing with a refill inserted in it. The refill usually includes a container to hold a volatile material. In some distributors, volatile material is passively emitted from them. In other distributors, a diffusion element is used to facilitate the distribution of the volatile material. Examples of diffusion elements include heaters, piezoelectric elements, fans, aerosol actuators, and the like. Regardless of the way in which the volatile material is emitted, once the volatile material has been spent from the refill, the refill is removed by a user and replaced with a new refill.
    [004] A type of volatile material distributor, which is sometimes referred to as an essential oil distributor for sockets, includes a housing and a heater disposed within the housing. A refill for use with an outlet essential oil dispenser usually includes a container with a volatile material in it and a wick in contact with the volatile material and extending out of the refill. After inserting the refill in the dispenser, at least part of the wick is
    2/33 disposed adjacent to the heater so that the volatile material that moves through the wick is volatilized by the heater. The volatile material dispenser includes a plug assembly having electrical rods extending outwardly from the housing. The electrical rods are inserted into a standard electrical outlet and, after that, supply electrical energy to the volatile material distributor. Essential oil dispensers for outlet can also use a fan to assist in the evaporation and distribution of volatile material.
    SUMMARY [005] In the illustrative embodiments, a volatile material distributor includes a housing having at least one wall and a cavity disposed within the housing and a refill having a volatile material in it and a wick in contact with the volatile material and extending to out of the refill. The dispenser additionally includes a heater arrangement arranged within the cavity and surrounding the wick when the refill is inserted into the dispenser. The heater arrangement provides a reduced energy consumption of at least about 30% compared to other similar volatile material distributors that have an average rate of weight loss that is similar to or less than the volatile material distributor.
    [006] In other illustrative embodiments, a volatile material distributor includes a housing having at least one wall and a cavity disposed within the housing and a refill having a volatile material and a wick in contact with the volatile material and extending out of the refill. The dispenser additionally includes a heater arrangement disposed within the cavity and disposed adjacent to the wick when the refill is inserted into the dispenser, where the heater arrangement has an efficiency factor of more than or equal to about 13.
    [007] In additional illustrative embodiments, a method of emitting a volatile material includes the step of supplying a volatile material distributor having at least one wall and a cavity disposed within the housing,
    3/33 where the housing accommodates a refill having a volatile material and a wick in contact with the volatile material and extending out of the refill. The method additionally includes the step of positioning a heater arrangement within the distributor, where the heater arrangement is configured to reduce the energy required to operate the distributor. Additionally, the method includes the step of operating the heater arrangement with an energy less than or equal to about 1.5 watts to achieve an average weight loss of at least 0.01 gram per hour.

    DETAILED DESCRIPTION [028J This description is aimed at energy efficient heater arrangements for volatile material distributors. While the present invention can be embodied in many different forms, several specific modalities are discussed here with the understanding that the present invention should be considered only as an example of the principles of the invention, and should not limit the invention to the illustrated modalities.
    [029] Referring to the drawings, figures 1 to 5 show a first embodiment of a volatile material dispenser 50 adapted to accommodate a refill 51, as seen in figures 1 and 2, including a container 52 with a volatile material in it , where container 52 is adapted to be retained by a housing 56. Container 52 includes a retention mechanism 54 (see figure 9) for maintaining a wick 60 within container 52 and a body 62 with the volatile material disposed therein. Body 62 includes a base portion 64 and opposing first and second side walls 66a, 66b which extend upward and outward before bending inwardly towards the first and second upper walls 68a, 68b, respectively. The first and second upper walls 68a, 68b are integral
    6/33 with a nip 70 (see figure 9). Similarly, opposite front and rear walls 72a, 72b, respectively, curve upward in the direction of narrowing 70.
    [030] The narrowing 70 of the refill 51 includes a threaded part arranged on an external surface and an opening 73 arranged through an upper part, where the opening allows access to the volatile material. The retention mechanism 54 is disposed within the nip 70 and additionally includes a sheath 75 that extends around at least a part of the wick 60 to protect it. Container 52 optionally additionally includes raised parts 76 extending outwardly from one or more of the opposite front and rear walls 72a, 72b. In one embodiment, the raised parts 76 are in the form of inverted wrap-around elements. Although a specific distributor 50 and container 52 are described with particularity, it is contemplated that the heater arrangements of the present invention can be used in conjunction with any type of electrical distributor employing a heater and any type of refill and / or container. For example, dispensers useful for the present invention include, but are not limited to, dispensers described in Belongia et al., US patent No. 7,840,123, Varanasi et al., US patent No. 6,968,124, Beland et al, US patent application publication No. 2011/0049259, Zobele, US patent application publication No. 2005/0180736, and Pedrotti et al, US patent No. 6,862,403. In addition, containers useful for the present invention include, but are not limited to, containers described in US Patent No. 7,032,831 and containers described in US Patent Application No. 12 / 969,261, filed December 15, 2010, both which are the property of the same assignee as that of the present invention.
    [031] The volatile material disposed in the container 52 can be any type of volatile material adapted to be distributed to an environment. For example, container 52 may include a cleaner, an insecticide, an insect repellent, an
    7/33 insect agent, disinfectant, mold or mold inhibitor, fragrance, disinfectant, air purifier, aromatherapy device, antiseptic, odor eliminator, volatile positive fragrance material, deodorizer , or the like, and combinations thereof. Additives can be included in the volatile material, such as, for example, fragrances and / or preservatives.
    [032] Turning now to figures 1 to 5, the housing 56 of the volatile material distributor 50 generally includes front and rear parts 90, 92 attached to each other to form an inner chamber or cavity 93 between the same. The front and rear parts 90, 92 also come together to form an opening 94 in a top of the housing 56 for the emission of volatile material through it. The refill 51 is inserted into the housing 56 by inserting the wick 60 upwardly into the chamber 93. Referring to figures 1 and 5, a plug assembly 96 extends from the rear 92 of the housing 56 and includes two electrical rods 98 adapted for insertion into a conventional outlet. While plug set 96 is illustrated as a conventional plug set for the United States, a plug set adapted for use in any other country can be used. In addition, plug assembly 96 may include any feature known in the art, for example, plug assembly 96 may be partially or fully rotatable.
    [033] While not shown in the figures of the present application, the dispenser 50 may include a face plate that is rotatably attached thereto, for example, as described in detail in Belongia et al., U.S. publication No. 20120275772.
    [034] As best seen in figures 2 and 3, a stationary support 100 is disposed within housing 56 and extends between the first and second sides 102, 104 of housing 56. Support 100 includes a generally flat wall 106 and first and second arms 108, 110 extending downward and to
    8/33 out of the opposite ends 112,114, respectively, of the flat wall 106 to the first and second sides 102, 104. The arms 108, 110 are integral with or otherwise connected to the first and second sides 102, 104 of the housing 56.
    ADJUSTMENT MECHANISM [035] Referring to Figures 4 and 5A, the flat wall 106 of the support 100 includes a circular opening 120 through it, where a cylindrical element 122 is formed within the circular openings 120. The cylindrical element 122 includes a section upper 124 which extends above the flat wall 106 and is partially enclosed by a cover 126 with an opening 128 for the wick 60, as will be discussed in more detail below. The cylindrical element 122 additionally includes a lower section 130 which extends below the flat wall 106 and includes first and second opposing channels 132, 134 formed within sides of the lower section 130 and extending to the flat wall 106. The cylindrical element 122 includes additionally third and fourth opposite channels 136, 138 formed within the front and rear sides of the lower section 130 and extending to the flat wall 106. A first part of an adjustment mechanism 139 includes three sets of notches 140a to 140c arranged on a surface inner 142 of the cylindrical element 122 in the upper and lower sections 124, 130. In particular, as seen in Figure 5, a first of the notch assemblies 140a is disposed within the lower section 130 above the opposing third and fourth channels 136, 138. The second and third sets of notches 140b, 140c are arranged within the upper section 124 above the first set of notches 140a. The function of the notches will be discussed in more detail later.
    [036] Four elongated guide rods 150 extend outwardly from the upper section 124 of the cylindrical element '122, as seen in figures 4 and 5, and are generally parallel to a longitudinal geometric axis 152 (see figure 5A) of the
    9/33 dispenser 50. A guide rod 150 is disposed between each adjacent channel 132, 134, 136, 138. While four guide rods 150 are presented, any number of guide rods 150 that perform the orientation function, as will be discussed below, can be used.
    [037] Adjustment mechanism 139 additionally includes a refill retainer 160, as best seen in figures 3 to 5A. The refill retainer 160 includes a cylinder 162 adapted for insertion into the cylindrical element 122 of the support 100, as will be discussed in more detail below. First and second flexible tabs 164 are arranged on opposite sides of cylinder 162. The tabs 164 are formed by kennels 166 on cylinder 162 and additionally include projections of external extension 168. The first and second rigid projections 170 extend outwardly from the sides front and rear of cylinder 162. Refill retainer 160 additionally includes an annular protrusion 172 (see figure 5A) that creates a generally flat surface and includes an opening 174 therethrough. The wick 60 of the refill 50 can be inserted through the opening 174, but the annular protrusion 172 prevents excessive insertion of the refill 51 in the dispenser 50.
    [038] Still referring to figures 3 to 5, cylinder 162 includes four elongated channels 180 extending downwardly from an upper projection 182 of cylinder 152 and generally parallel to longitudinal geometric axis 152 of distributor 50. An elongated channel 180 is arranged between each tongue 164 and an adjacent rigid projection 170.
    [039] As noted in figures 3 through 5, the refill retainer 160 additionally includes two arms 182 extending out and down from the front and rear sides of a bottom edge 186 of cylinder 162. Each arm 182 includes a opening 188, respectively, through it. The openings 188 can be formed in a shape that conforms to the raised parts 76 in the refill 51. The openings 188 can optionally have any shape that would assist in retaining
    10/33 refill 51. Optionally, arms 182 and / or refill 51 may include any features that assist in fixing and retaining refill 51 on arms 182.
    [040] The adjustment mechanism 139 is mounted by inserting the cylinder 162 of the refill retainer 160 in the lower section 130 of the cylindrical element 122 of the support 100. In this way, the first and second flexible tabs 164 of the cylinder 162 are aligned within the first and second opposite channels 132, 134 on the side of the lower section 130 and the rigid projections 170 are aligned within the third and fourth opposite channels 136, 138 on the front and rear side of the lower section 130. At the same time, as best seen in the figure 5A, the four elongated guide rods 150 in the upper section 124 of the cylindrical element 122 are aligned within four elongated channels 180 extending outwardly from the cylinder 162. Each of these characteristics acts to orient the refueling retainer 60 within the cylindrical element. 122.
    [041] Once aligned, the refueling retainer 160 is pushed into the cylindrical element 122 until the projections 168 extending outward from the tongues 164 are disposed within the first set of notches 140a. The assembly steps of the adjustment mechanism 139 can be performed during manufacture and before purchase by a customer, or can optionally be performed by the consumer. Optionally, one or more features can be included to prevent removal of the refill retainer 160 from the assembly of the cylindrical element 122.
    [042] When using distributor 50, a user may desire a higher or lower emission of volatile material. The refill retainer 160 can therefore be moved up and down to provide different levels of emission. In particular, when the projections 168 are arranged within the first set of notches 140a, the wick 60 is partially arranged within the heater 202, hungry
    11/33 thus lowering the level of emissions. The movement of the refill retainer 160 so that the projections 168 are arranged within the second set of notches 140b moves the refill 51 upwards, thus moving the wick 60 further into the heater 202. A higher level of emission it is provided by moving the projections 168 into the third set of notches 140c. As can be understood by those skilled in the art, a user must change the intensity level of the dispenser 50. The intensity level is controlled by the movement of the refill retainer 160 (and thus the position of the refill 51 and the wick 60) towards and away from heater 202.
    HEATER ARRANGEMENT [043] Referring now to Figures 2, 3, 5A and 5B, the distributor 50 additionally includes a first embodiment of a heater arrangement 200 employing a heater or resistor 202. As noted in Figures 15 and 16, which show In two variations of heater 202, heater 202 in the form of a resistor includes a hollow ceramic cylinder 204 with a resistive metal oxide coating 206 which is deposited by spray coating or spray coating on the hollow ceramic cylinder 204. A spiral pattern 208 can be formed in the resistive metal oxide coating 206 to create a desired resistance value for heater 202. Alternatively, ceramic cylinder 204 can be coated with a metal oxide coating 206 having a precise resistance value, thereby eliminating , the need for spiral cutting. The metal end caps 210 are snapped onto the first and second ends 212, 214 of the hollow ceramic cylinder 204. The metal end caps 210 include caps 220 including a hollow cylindrical cavity 222 and one or more integral connectors 224 with or connected to the lids 210. Lids 210 fit over the ends 212, 214 of cylinder 204 and connector 224 extends in torso, at and away from cylinder 204 and can terminate at terminals 230 (see figure
    12/33
    15), where any connector 224 or terminals 230 connect to an outlet, circuit panel and / or other electrical components of the volatile material distributor 50. Heater 202 may be coated with an insulating, dielectric and / or flame resistant material or can be placed in a ceramic or plastic block. In one embodiment, resistor 202 has a nominal resistance of between about 14 and about 16 Kohms with a tolerance of 5%, a maximum energy of about 3 Watts, and an operating voltage of between about 100 volts and about 230 volts. While a ceramic tube is being described, a wire can be wound inside a tube to create the heater.
    [044] While figures 15 and 16 are described as a ceramic cylinder coated with resistive metal oxide, the ceramic cylinder can optionally be coated with a carbon film, a resistive metallic film, or a coefficient-like material. positive temperature (PTC). In other illustrative embodiments, the cylinder can be wrapped with a resistive wire or flexible heating element. In other additional illustrative embodiments, the cylinder may be formed from a PTC thermistor material (instead of a coated ceramic). In other additional illustrative embodiments, a plurality of PTC resistors or thermistors can be arranged in a tubular arrangement or within a tubular structure to form a tubular heating arrangement. In other alternative illustrative embodiments, two or more of the heaters shown in figures 15 and 16 can be used. In illustrative modalities, two or more heaters are stacked in a vertical manner and a refill wick is inserted through two or more heaters. In this way, one or more of the heaters, which can be operated independently, can be operated at any time. In an illustrative embodiment in which two heaters are stacked, a first heater having a first resistance can be activated to a low level of heat, a second heater having a second resistance greater than the
    13/33 first resistance can be activated for an intermediate level of heat, and both heaters can be activated for a high level of heat. Optionally, multiple resistors can be formed in a single ceramic tube to create the same effect. It should be understood that any combination of heaters, resistance levels, and / or heat levels are within the scope of this application. In additional alternative embodiments, two or more heaters or heater arrangements may be associated with two or more different refills to provide multiple fragrances.
    [045] As best illustrated in figure 5B, heater 202 can be arranged within a cylindrical container 240. Container 240 includes a bottom plate 242 that is snap-fit or is otherwise attached to a lower end 244 of the container 240. The bottom plate 242 includes a central opening 243 and may include a plurality of auxiliary openings 246 for migration of heat from heater 202 therethrough. An upper plate 248 is snap-fit or otherwise attached to an upper end 250 of the container 240 to, with the lower plate 242, enclose the heater 202 inside the container 240. The upper plate 248 includes a central opening 250 which may include one or more auxiliary openings 252 for heat migration through it. One side of the container 240 includes one or more openings to accommodate the connectors 224 extending from the heater 202. The container 240 additionally includes at least one rod 254 or other support for securing the heater to the housing 56.
    [046] A space can be arranged between an external periphery or external diameter of the wick 60 and an internal periphery internal diameter of the heater 200 or cylindrical container 240 that can hold the heater 200. The space must be large enough to allow the flow of enough air through heater 200 or heater arrangement 202, but small enough to provide sufficient heat transfer to wick 60. In illustrative embodiments, the space is between
    14/33 about 0.5 mm and 2.5 mm. In the alternative illustrative modalities, the space is between about 1.0 millimeter and about 2.0 millimeters. In other illustrative modalities, the space is about 1.0 millimeter or about 1.5 millimeters.
    [047] With reference to figure 2, a refill 51 is inserted into the housing 56 by positioning the wick 60 inside the cylinder 162 of the refill retainer 160 and guiding the wick 60 through the cylindrical element 122 of the support element 100 and additionally through the central opening 243 in the bottom plate 242. In this way, a part of the wick 60 is arranged within a cylindrical core of the heater 202.
    EXPERIENCE [048] An experiment was conducted to measure the overall efficiency of heater 202 illustrated in figure 16 compared to heaters in similar devices currently on the market. With reference to figure 26, five devices were tested. A first device 800 is similar to the device described here with respect to figures 1 to 6 and included in heater 202 as illustrated and described with respect to figure 16 and additionally includes a cover attached to it, as described above. A second 802 device is a device currently sold by S.C. Johnson & Son, Inc. under the name Glade® Plug-lns® and detailed in a U.S. publication by Belongia et al. No. 2012-0275722. A third device 804 is a device sold by Reckitt Benckiser under the name Air Wick®. A fourth device 806 is a device sold by Procter & Gamble under the name Febreze® Noticeables ™ and detailed in U.S. Patent No. 7,722,807. A fifth device 808 is currently sold by Bath & Body Works, Inc. and is similar to the device detailed in U.S. Patent No. 6,236,807. Six of each 800-808 device was used to test and weight loss data for each set of devices was measured.
    [049] A single component proxy formula was used during the test, in particular, Tetradecan 99% (C14H30). Tetradecan 99% was selected as
    15/33 a proxy as it more closely reproduces the weight loss of a volatile material in the form of a fragrance. In particular, in the preliminary test, Tetradecan 99% exhibited a weight loss and a release rate of around 23 milligrams per hour, which is in the middle of the deliberation and weight loss rate of most fragrances. More specifically, the normal release and weight loss rate of most fragrances is between about 10 and about 40 milligrams per hour. Weight loss refers to the rate at which a volatile material is exhausted from the refill. The weight loss for a particular volatile material is equal to the rate at which the volatile material is emitted to the surroundings, which is often referred to as the exit rate or release rate.
    [050] The refills were filled with 19.8 mm of proxy formula and inserted in each of the 800 to 808 devices. In particular, the refill used for the first and second 800, 802 devices was a refill sold by SC Johnson & Son , Inc. and detailed in US Patent No. 8,197,765. The refills used with the third, fourth and fifth devices 804, 806, 808 were currently sold with the respective devices. Regarding the fourth device 806, two united refills were filled and inserted in the two compartments of the device 806. With respect to the refills for the devices 800, 802, new bottles and wicks were used that were not previously used with another volatile material. The bottles and sockets of the refills for devices 804, 806, 808 were purchased, drained, rinsed in isopropyl alcohol and left to dry before supplying the proxy formula. The wicks for such refills were placed on absorbent paper towels and allowed to dry for about 96 hours before insertion in the bottles having a proxy formula.
    [051] The test facility was an environmentally controlled environment maintained at a temperature of 70 F (+/- 2 F) with a humidity of 50% relative humidity (RH) (+/- 5%) and an exchange rate air flow from 22 +/- to 4 air changes per
    16/33 hour. A constant voltage power supply (in the form of AC electrical output strips) capable of supplying 120 VAC +/- 0.5 volt was used to energize the devices 800 to 808. Another equipment used during the experiment was a calibrated balance capable of to obtain a resolution of 0.01 gram, a calibrated multimeter capable of a resolution of at least 0.1 volts, and a calibrated energy meter.
    [052] During an initial experiment setup phase, the initial resistance, current draw and energy input for each device were measured and recorded. The refills were then installed and a combined weight of each device and refill was measured. After installing the refill, testing personnel ensured that the wicks were not touching the respective heaters and the devices were installed inside the outlets, where a spacing of at least 6 inches was confirmed between each adjacent device (both horizontally and vertically), as noted in figure 27. It was then verified that the temperature, humidity, air exchange rate, and energy supply were within acceptable limits. Finally, for each device including an intensity level switch (all but the fifth device 808, which did not have an adjustment device), the intensity of the respective device was set to high.
    [053] During the testing phase of the Experiment, after the devices were installed into the outlets, the weight loss test was conducted once a day for a total of 10 continuous days. As with the initial weight measurement, the weight of each combined device and refills was measured. A weight loss was calculated for each device using the previous and current weight measurements and the weight loss was recorded. An Average Hourly Weight Loss for each device was calculated using weight loss values for 3 to 10 days and an Average General Hourly Weight Loss for each set of devices was determined by averaging the Average Hourly Weight Loss for each device of that type . During the
    17/33 test phase, the voltage was checked twice a week using a calibrated voltmeter to ensure that it was within proper limits.
    [054] In the Experiment analysis phase, after the test was completed and the appropriate data was collected, a device efficiency factor was calculated for each of the 800 to 808 devices using the equation:
    Device Efficiency Factor = Average General Weight Loss / Energy
    The results of the analysis phase are illustrated in Table 1 below.

    [057] In short, the first 800 device has a significantly higher output rate / release rate / weight loss per unit watt than any of the tested devices. In fact, the weight loss rate / release rate / output rate per watt of the first device 800 is greater than twice the device with the next highest efficiency, the fifth device 808. Otherwise, the amount of The energy required to operate the first device 800 is a fraction of the energy required for devices 802, 804, 806, 808 to achieve the same output rate / release rate / weight loss or greater. The net effect with the first 800 device is energy savings and efficiency.
    [058] In the illustrative modalities, a weight loss of at least 0.02 grams per hour is maintained using an energy input less than or equal to 1.5 watts. In alternative illustrative modalities, a weight loss of at least 0.2 grams per hour is maintained using an energy input of less than or equal to about 1.0 watts. In other illustrative embodiments, a weight loss of at least 0.1 gram per hour is maintained using an energy input of less than or equal to about 1.5 watts. In other illustrative modalities, a weight loss of at least 0.1 gram per hour is maintained using
    19/33 a power input of less than or equal to about 1.0 watts.
    [059] In the illustrative embodiments, the heater arrangements described here provide a reduced energy consumption of at least about 20% compared to other similar volatile material distributors that have an average rate of weight loss that is similar to or less at the average rate of weight loss for distributors employing the heater arrangements described here. By a reduced energy consumption of at least 20% it means that at least 20% less energy is used to obtain the same average rate of weight loss. In other illustrative embodiments, the heater arrangements provide a reduced energy consumption of at least about 30%, at least about 40%, at least about 50%, or at least about 60%, compared to other distributors of similar volatile material that have an average rate of weight loss that is similar to or less than the average rate of weight loss for distributors employing the heater arrangements described here.
    [060] In the illustrative modalities, the efficiency factor of one or more of the heaters described here is greater than or equal to about 13. In other illustrative modalities, the efficiency factor of one or more heaters described here is greater than or equal to about 15, greater than or equal to about 20, or greater than or equal to about 25.
    ALTERNATIVE ADJUSTMENT MECHANISMS [061] A second embodiment of a volatile material distributor 260 is shown in figures 6 to 10. The distributor 260 includes a housing 262 having front and rear parts 264, 266 attached to each other to form a chamber or internal cavity 268. The front and rear parts 264, 266 also come together to form an opening 270 in a top of the housing 262 for the emission of volatile material through it. Refill 51 is inserted into housing 262 by
    20/33 insertion of wick 60 upwardly into chamber 268. Referring to figures 6 and 9, a plug assembly 272 extends from rear 266 of housing 262 and includes two electrical rods 274 adapted for insertion into a conventional outlet. While plug set 272 is illustrated as a conventional plug set for the United States, a plug set adapted for use in any other country can be used. In addition, plug assembly 272 may include any features known in the art, for example, plug assembly 272 may be partially or fully rotatable.
    [062] As best illustrated in figures 7 to 9, a stationary support 280 is disposed within housing 262 and extends between the first and second sides 282, 284 of housing 262. Support 280 includes a generally flat wall 286 and first and second arms 278, 280 extending downwardly and outward from opposite ends 292, 294, respectively, of the flat wall 286 to the first and second sides 282, 284 of housing 262. As best illustrated in Figure 10C, the support 280 additionally includes a flexible tongue 300 formed within an upper edge 302 of the flat wall 286. In particular, two partitions 304 extend inwardly from the leading edge 302 to form the tongue 300, which flexes around the point 306. A projection 308 extends upwardly from an upper surface 309 of the tongue 300 and includes a curved outer surface 310. A cylindrical channel 311 is formed through the support 280 for p position the wick 60, as will be discussed in more detail below.
    [063] An adjustment wheel 312 is attached to stationary support 280 and includes a base 313 with an outwardly curved wall 314. Wall 314 provides a button 316 that extends through an opening 318 in the front 264 of housing 262. An outer surface 320 of wall 314 may include a plurality of indicia 322 to provide a visual cue of an adjustment wheel position 21/33 and 312 (e.g., an intensity level). An inner surface 324 of wall 314 may include a plurality of notches 326 which are aligned with the indicia 322 and which assist in setting an intensity level for the distributor 260, as discussed below.
    [064] As seen in figure 10B, the adjustment wheel 312 additionally includes a first cylindrical wall 330 extending downwardly from the base 313 and disposed into the wall 314. Referring to figure 10A, the adjustment wheel 312 includes a second cylindrical wall 332 extending upwardly from the base 313 and spaced between the first cylindrical wall 30 and the wall 314. Two spiral openings 334 are disposed within the second cylindrical wall 332, the function of which will be discussed in more detail below.
    [065] Still with reference to figure 10A, dispenser 260 additionally includes a heater arrangement 340 similar to heater arrangement 200 of figures 1 to 5B. Similar components will therefore be numbered accordingly. A cylindrical extension 342 extends downwardly from the container 240 and has a diameter slightly larger than the diameter of the container 240. The extension 342 includes two flexible tabs 344 on either side of the extension 342, where each tab 344 is formed by two channels 346 and includes a cylindrical projection of external extension 348.
    [066] During manufacture, the adjustment wheel 312 is fixed to the support 280 by inserting the first cylindrical wall 330 of the adjustment wheel 312 into the cylindrical channel 311 of the support 280. As the adjustment wheel 312 is pressed against the support 280, the projection 308 flexes around the point 306 until the projection 308 is arranged within one of the notches 326 within the inner surface 324 of the wall 314 of the adjusting wheel 312.
    [067J The heater arrangement 340 is fixed to the adjustment wheel 312 by flexing the tabs 344 inwards and inserting the extension 342 on the second wall
    22/33 cylindrical 332 of the adjustment wheel 310 so that the projections 348 extend into the spiral openings 334. After mounting the distributor 260, the rods 254 extending outwardly from the heater arrangement 340 are supported in a anti-rotation wall 360 extending from housing 262, thus preventing rotation of the heater arrangement 340.
    [068] During operation, a user turns the knob 316 to adjust the intensity of the heater 202. When the knob 316 is set to a lower intensity, the cylindrical projections 348 are arranged inside the lower ends 362 of the spiral openings 334. As the knob 316 is rotated in a clockwise direction, the adjustment wheel 310 is rotated, but the heater arrangement 340 remains stationary due to the anti-rotation wall 360. The cylindrical projections 340 rise through the spiral openings 334 towards the upper ends 364 of the spiraled openings 334, thereby causing the heater arrangement 340 to move upward and increase a level of intensity. In particular, heater 202 is arranged around an exposed area of the wick which is larger than in other positions (for example, the upper part of the wick 60 which does not have the sheath 75). The knob 316 can be rotated to move the cylindrical projections 348 into the spiral openings 334 to change the intensity from a lower intensity (at the lower ends 362 to the higher intensity at the upper ends 364).
    [069] A third embodiment of a volatile material distributor 450 is shown in figures 11 to 14. Similar to the previous embodiments, distributor 450 includes a housing 452 having front and rear parts 454, 456 attached to each other to form a chamber or internal cavity 458 between them. The front and rear parts 454, 456 also join to form an opening 460 in a top of the housing 452 by inserting the wick 60 upwardly into the chamber 458. Referring to figures 11 and 12, a plug assembly 462
    23/33 extends from the rear 456 of housing 452 and includes two electrical rods 464 adapted for insertion into a conventional socket. While plug set 462 is illustrated as a conventional plug set for the United States, a plug set adapted for use in any other country can be used. In addition, plug assembly 462 can include any features known in the art, for example, plug assembly 462 can be partially or fully rotatable.
    [070] As best seen in Figures 12 and 14, dispenser 450 includes a two-piece adjustment mechanism 470 including a refill retainer 472 and an adjustment wheel 474. Refill retainer 472 includes a cylinder 476 having first and second tongues 478 formed on the upper outer edge 480 of cylinder 476 on the front and rear sides of cylinder 476. Each tongue 478 is formed by partitions 481 which allow the tongues 478 to flex. A cylindrical projection 482 extends outwardly from each tongue 478. Limiting projections 484 extend outwardly from cylinder 476 and are spaced below the tongues 478.
    [071] Referring to figures 12, 14 and 15, the refill retainer 472 additionally includes an annular protrusion 490 that creates a generally flat surface and includes an opening 492 therethrough. The wick 60 of the refill 61 can be inserted through the opening 492, but the annular projection 490 prevents excessive insertion of the refill 51 into the dispenser 50.
    [072] The refill retainer 472 additionally includes first and second arms 494 extending outward and downward from the front and rear sides of a lower edge 498 of cylinder 476. Each arm 494 includes an opening 500 therethrough. The openings 500 can be formed in a shape that conforms to the raised parts 76 in the refill 51. The openings 500 can optionally have any shape that assists in retaining a refill. Also, optionally, the arms 494 and / or the refill 51 can include any features that assist in fixing
    24/33 tion and retention of refill 51 on arms 494.
    [073] With reference to figures 12 and 14, the adjustment wheel 474 includes a button 510 having a flat wall 512 through a center of and in perpendicular to the button 510 and having an opening 514 through it. The adjusting wheel 474 additionally includes a cylindrical wall 516 extending downwardly from the button 510, where the cylindrical wall 516 includes two spiral openings 518 and two cutouts 520 spaced below the openings 518 and forming support surfaces 522. The supporting surfaces 522 are generally parallel to the spiral openings 518. The button 510 can be rotated in a similar manner to the embodiment of figures 7 to 11, except that the refill 51 is moved up and down, instead of the heater arrangement 200.
    [074] The dispenser 450 additionally includes a heater arrangement 524 which is identical to heater arrangement 200 of figures 1 through 6. The heater arrangement is attached to housing 452 as described with reference to the embodiment of figures 1 and 6 or in any other appropriate way. The heater arrangement is spaced above the 474 adjustment wheel. While the manual adjustment mechanisms are shown in the drawings and in the modalities detailed here, an electrical adjustment mechanism can be used alternatively. For example, a multi-position slide switch can be operationally connected to a drop resistor circuit to vary a temperature of any of the heaters described here.
    IMPROVEMENTS OF THE HEATER ARRAY [075] The characteristics and components of the heater arrangement of figures 17 to 25 can be used in combination with the arrangements of heaters and / or with heaters described in relation to the modalities of figures 1 to 16 to improve the efficiency of such heaters and / or heater arrangements.
    [076] Referring to figure 17, a heater arrangement 550 is illus
    25/33 drawn within a volatile material distributor 551 and may include a typical ceramic heating block 552, which includes one or more resistors (not shown) arranged within heating block 552, or any heater arrangement as described with respect to to figures 1 to 16. When the resistors are activated, the heat from the resistors is conducted throughout the ceramic heating block 552. The heater arrangement 550 may additionally include a heat strip 554 attached to a surface 555 of the heating block 552 which faces wick 60 of refill 51 (when inserted in dispenser 552). The heat strip 554 generally includes a U-shaped wall 556 and a flat wall 558 connected to the ends 560, 562 of the U-shaped wall 556. The flat wall 558 is arranged against the surface 555 of heating block 552. A heat strip 554 can be attached to heating block 552 by a connector 564 that generally extends transversely to flat wall 558 and on an upper surface 566 of heating block 552. Optionally, heat strip 554 can be attached to heating block 552 in any suitable way. Preferably, the heat strip 554 is made of a conductive material, such as metal. While the heat range 554 is described as having a U-shape, other arrangements and / or shapes are possible.
    [077] With the characteristics of figure 17, the heat travels through the heat band 554 by conduction, thus creating a heat ring around the wick 60. The heat from the ring travels internally through the air space towards the wick 60 through conduction and radiation and is trapped in a space 570 between heat band 554 and wick 60, thus increasing the overall temperature in space 570 and therefore wick 60, creating a uniform application of heat across around a circumference of the wick 60, and thus additionally increasing the volatilization of the volatile material in the wick 60. · -.
    [078] Additional improvements are presented in a heating arrangement
    26/33 pain 580 as seen in figures 18 and 19, which is incorporated here within a volatile material distributor 582. The heater arrangement 580 may include a resistor 584 extending from a circuit panel or other component within the volatile material dispenser 582. Resistor 584 can be encapsulated within a ceramic heating block 586 or can be otherwise encapsulated or spaced from a wick 590. A refill 588 for use with heater arrangement 580 may be similar to the refill 588 discussed with respect to the first embodiment, except that refill 588 includes a wick 590 having an opening or cavity 592 for inserting resistor 584 and / or ceramic heating block 586. Wick 590 may additionally include a sheath 594 arranged around parts of the wick 590 that are close to the heater arrangement 580.
    [079] In a first variation of the heater arrangement 580, as seen in figure 18, resistor 584 and / or ceramic heating block 586 can be suspended within the volatile material distributor 582 and cavity 592 in wick 590 can be created by a hollow cylinder extending across an upper surface 596 of wick 590. During insertion of refill 588, wick 590 can be aligned with resistor 584 and / or ceramic heating block 586 so that resistor 584 and / or the ceramic heating block 586 are arranged inside the wick 590 by fully inserting the refill 588 into the volatile material distributor 582. In a second variation of the heater arrangement 580, as seen in figure 19, resistor 584 and / or the ceramic heating block 586 can extend outwardly from one or more components into the volatile material distributor 582. Cavity 592 can be formed through side 600 of wick 590. Durant and inserting the refill 588, the cavity 592 formed through the side 600 of the wick 590 can be aligned with resistor 584 and / or ceramic heating block 586 so that resistor 584 and / or ceramic heating block 586 is arranged inside the wick 590 by fully inserting the 588 refill into the dispenser
    27/33 volatile material 582.
    [080] The characteristics of the heater arrangement 580 of figures 18 and 19 provide an increased heater efficiency since the wick 590 is heated evenly. In addition, due to the proximity of resistor 584 and / or ceramic heating block 586 to wick 590 and the fact that resistor 584 and / or ceramic heating block 586 is disposed within wick 590, little heat is lost to the surroundings (or other components of the distributor 580) and the wick 590 is the container for most of the heat emitted.
    [081] An additional 620 heater arrangement is shown in the figure
    20. Heater arrangement 620 may include a typical ceramic heating block 622, which includes one or more resistors (not shown) arranged within heating block 622, or any heater arrangement as described with reference to figures 1 through 16 When the resistors are activated, the heat from the resistors is conducted through the ceramic heating block 622. The heating block 622 is different from the previous ceramic heating blocks in that it is arranged vertically. In particular, the heating block 622 is a straight rectangular prism with three different dimensions, where the heating block 622 is arranged with a longer dimension of the three dimensions having a longitudinal geometric axis 64 which is parallel to a longitudinal geometric axis 626 of the wick 60. The resistors contained within the heating block 622 may also have a longitudinal geometric axis that is parallel to the longitudinal geometric axis 626 of the wick 60. The vertical arrangement of the heating block 622 allows heat to be directed over a longer wick length 60, thus increasing the volatilization of the contained volatile material.
    [082] In a heater arrangement 640, as shown in figure 21, both a 644 heat band (as seen in figure 17) and a vertical heating block 642 (as seen in figure 20) or any heating arrangement
    28/33 described in figures 1 to 16, can be used to further increase the amount of heat reaching the wick 60 and to increase the overall efficiency of the heater arrangement 640. An insulator 646 can optionally surround the heat 644 and at least part of the heating block 642 to retain heat within the heater arrangement 640.
    [083] An additional heater arrangement 660 is shown in figure 22. Heater arrangement 600 may include a ceramic heating block 662 having a first section 664 with a rectangular cross section and a second integral section 666 with a generally circular cross section and extending away from the first section 664. A resistor 668 can be arranged in a cavity 670 disposed within the first section 664 (and can optionally be encapsulated in a ceramic or other conductive material) and a channel 672 can be arranged through second section 666. Alternatively, any of the heater arrangements described with respect to figures 1 to 16 can be used. A metal rivet 674 can be attached to the upper and lower surfaces 676, 678 of the second section 666 with rivet 674 extending through and covering a surface of channel 674. Refill 51 is inserted into channel 672 of heating block 662 of so that metal rivet 674 surrounds wick 60. When resistor 668 is activated, heat travels through conduction through heating block 662. If heating block 662 does not include rivet 674, heat travels in all directions 60 wick, but the heat is lopsided. In particular, one side of channel 672 closest to resistor 668 receives slightly more heat than an opposite side of channel 672. When metal rivet 674 is used, the heat reaching metal rivet 674 is conducted rapidly throughout the rivet 674 to distribute heat evenly within rivet 674 and therefore to wick 60.
    [084] In the 680 heater arrangement, as noted in figure 23, the dis
    29/33 heater position 680 may include a typical ceramic heating block 682, which includes one or more resistors (not shown), as described in detail above, or any heater arrangement as described in figures 15 or 16. An insulator 684 it can be arranged on and covered a major part of the heating block 682, where the insulation 684 can include a space 686 where the heating block 682 is not covered. The space 686 can be aligned with a wick 60 of a refill 61 by inserting the refill 61. Insulation 684 prevents the migration of heat in directions other than in the direction of wick 60 and space 686 allows the migration of heat from the heating 682 towards wick 60. As with other modalities, the focus of heat emitted by heating block 682 and the reduction in wasted heat (moving in other directions except in the direction of wick 60) is minimized.
    [085] A heater arrangement 700, as shown in figure 24, may include a typical ceramic heating block 702, which includes one or more resistors (not shown), as described in detail above, or any other of the heater arrangements such as described with reference to figures 1 to 16. The heater arrangement 700 can additionally include a heat reflector or insulator 704 disposed opposite heating block 702. The reflector or insulator 704 can extend from a generally flat surface 706 and having a curved wall 708 with a generally elliptical top edge 710. The top edge 710 of the wall can curve upwardly as it moves away from the heating block 702 so that a higher point of the wall 708 is disposed opposite the heating block 702.
    [086] When a refill 61 is disposed within the heater arrangement 700 of figure 24, part of the heat emitted by the heating block 702 reaches the wick 60, but much of the heat passes through the wick 60. If a reflector is used, the heat that passes to wick 60 and hits reflector 704 is reflective back to wick 60. If a
    30/33 insulator 704 is used, the heat that passes through the wick 60 is captured inside the insulator 704 and aggregates inside the insulator 704, so that when enough heat is trapped inside the insulator 704, the heat is pushed towards the wick 60 While the reflector or insulator 704 is illustrated as having a specific configuration, the configuration can be changed without departing from the scope of the present invention. For example, the reflector or insulator 704 can be a full semicircle or it can extend from heating block 702. Various other configurations are possible. In addition, any number of reflectors and / or insulators can be used. If a reflector is used, the reflector can be made up of one or more reflective materials, including, but not limited to, aluminum foil or any other suitable thermally reflective material and an insulator is used, the insulator can be made up of one or more insulating materials, including, but not limited to, polystyrene, fiberglass, rigid ceramic, polypropylene, or any other insulating material or materials. A flexible or formable material can also be used as an insulator, for example, a ceramic tape.
    [087] As noted in figure 24, the reflector or insulator 704 can be used in combination with a reflector 720 mounted on an internal surface 722 of the front and / or rear 90, 92 of the housing 56. Any part or all of an internal surface 722 can include reflector 704 so that the heat emitted by heating block 702 can continue to bounce around a chamber 724 until it is absorbed by wick 60. Although some of the heat can be lost, more heat than in the distributors will be absorbed by wick 60, thus creating a more efficient heater arrangement 700.
    [088] Another heater arrangement 750 is shown in figure 25. A volatile material distributor 752 on which the heater arrangement 750 is arranged may include a platform 754 to hold a heating block 756 similar to any of the heating blocks heating or heater arrangement
    31/33 described here. Alternatively, heating block 756 can be replaced with any suitable heater. The heater arrangement 750 may additionally include an integral aluminum cylinder 758 with or otherwise attached or connected to the platform 754 or another component of the distributor 752. A channel 760 extends through the aluminum cylinder 758 and can be adapted for insertion of a wick 60 through it. The heating block 756 (or another heater) can be adjacent, spaced from, or in direct contact with the aluminum cylinder 758. When the heating block 756 is activated, the heat produced travels by conduction through the aluminum cylinder 758 , thus forming a heat ring around the wick 60. The closer the heating block 756 is to the aluminum cylinder 758 (connected directly to), the more efficient the heat transfer. In this way, heat is applied consistently to an annular surface of the wick 60.
    [089] Although the heater arrangements here are described as being used with dispensers that use refills with scented plug oils, the heater provisions can be used for any electrical distributor to which any type of volatile material is distributed from any type of refill by means of a heater. Optionally, a distributor employing any of the heater arrangements described here may additionally include one or more heaters and / or additional devices for distributing volatile material, for example, one or more among a fan, a piezoelectric element, and / or other components arranged in a housing to help facilitate the release of volatile material. In addition, one or more of the same heater arrangements or different heater arrangements as described herein can be employed within the same volatile material distributor.
    . [090] Those skilled in the art should understand that variations in heater arrangements as described here can be used. For example, any
    32/33 The number of characteristics of any of the modalities presented here can be combined to further increase the efficiency of the heater and reduce energy consumption as a whole.
    [091] The heater arrangements described here more efficiently focus heat around a circumference of the wick and over a longer length of the wick. The heater arrangements described here can include just one heater or can include any number of other components, as described in detail above.
    [092] Any of the modalities described here can be modified to include any of the structures or methodologies described in relation to other modalities.
    [093] Additionally, despite the directional terminology, such as, front, back, top, bottom, top, bottom, etc. can be used throughout this specification, it should be understood that such terms are not limiting and are only used here to convey the orientation of different elements with respect to each other.
