[0047] Next, each embodiment detailed in the present invention will be described with reference to the drawings. When the number, quantity, or similar appears in the embodiments below, the scope of the present invention will not necessarily be limited to that number, quantity, or the like, unless expressly indicated. In the described embodiments, the same portions or corresponding portions adopt the same reference characters and their description will not be repeated. The combination of aspects in the embodiments, as appropriate, is originally encompassed, unless expressly stated otherwise. FIRST ACHIEVEMENT LIQUID SPRAYING APPLIANCE 100
[0048] Referring to Figure 1, a liquid spraying apparatus 100 will be described in accordance with the present embodiment. Figure 1 is a perspective view showing an external structure of the liquid spraying apparatus 100. The liquid spraying apparatus 100 includes a body part 20 and a bottle unit 30. BODY PART 20
[0049] The body part 20 has a power breaker 21 on its surface. Inside the body part 20, an electrical power source (not shown), an electrical circuit (not shown), and the like, which are used to energize the liquid spraying apparatus 100 (vibrate a siren oscillator) are provided. 40, as will be described later). The bottle unit 30 is detachably attached to the body part 20. BOTTLE UNIT 30
[0050] In the following, bottle unit 30 will be described in detail with reference to Figures 2 to 8. Figure 2 is a perspective view showing bottle unit 40. Figure 3 is a first perspective view showing a disassembled state of the bottle unit 30. Figure 4 is a second perspective view showing a disassembled state of the bottle unit 30. Figure 5 is a cross-sectional view showing a disassembled state of the bottle unit 30.
[0051] Figure 6 is a perspective view showing a cross section taken along line VI-VI in Figure 2. In Figure 6, a member of mesh 1 (see Figures 3 to 5) (which will be described more details), is not shown for illustration purposes. As in Figure 6, mesh member 1, support members 50, 52, sealing support assembly 51, and outer mesh box 55 (which will also be described in detail later) are not shown. Figure 7 is a cross-sectional view corresponding to Figure 6. Figure 8 is an enlarged cross-sectional view of and around mesh member 1 in Figure 7.
[0052] As shown in Figures 2 to 5, the bottle unit 30 includes a mesh member 1 (see Figure 1 and Figures 3 to 5), bottle part 31 (liquid storing part), and siren oscillator 40 ( vibrating source (Figures 3 to 5)). MESH MEMBER 1
[0053] The mesh member 1 has a large number of micropores (not shown). Mesh member 1 is made of, for example, Ni-Pa (Nickel-Palladium) bonded in a predetermined relationship. As will be described in more detail below, the mesh member 1 (see Figures 1 and 3 to 5) is arranged to cover a surface 42 of the front end 41 of the siren oscillator 40. BOTTLE PART 31
[0054] Referring to Figures 5 to 8, the bottom of the bottle part 31 is made at an angle. A liquid L (see Figure 7), such as a medical fluid, is stored in the bottle part 31.
[0055] The bottle part 31 is provided with a liquid inlet 33 disposed opposite the siren oscillator 40, and the front end opening 42 is gradually tapered towards the siren oscillator 40. A box 35 is affixed to in order to close the liquid inlet 33. The box 35 is pivotally supported by a support part 35T in the direction of the AR 35 arrow (see Figure 2).
[0056] With the box 35 affixed to the bottle part 31, the liquid inlet 33 of the bottle part 31 is closed. The state in which the housing closes the liquid inlet 33 is maintained by an attachment part 35K provided at the top of the housing 35.
[0057] The opening of the front end 32 of the bottle part 31 is disposed opposite the front end 41 of the siren oscillator 40. As will be described in more detail later, the liquid L, stored in the bottle part 31, is supplied from the outside of the front end 41 of the siren oscillator 40 to the surface 41 of the front end 41.
[0058] Here the bottle part 31 is made so that the liquid L does not reach the vicinity of a contact part (atomizing part) between the surface (surface 42 in Figure 3, etc.) of the front end 41 of the siren oscillator 40 and the mesh member 1 when the liquid spraying apparatus 100 (see Figure 1) is maintained in a horizontal state (horizontal state shown in Figure 7). On the other hand, the bottle part 31 is formed so that the liquid L reaches the proximity of the contact part (atomizing part) of the surface (surface 42 in Figure 3, etc.) of the front end 41 of the siren oscillator 40 and the mesh member 1 in the spray state (inclined state, shown in Figure 9), in which the liquid spraying apparatus 100 (see Figure 1) is tilted towards the siren oscillator 40.
[0059] Specifically, in the present embodiment, the bottle part 31 has a higher capacity section B and a lower capacity section b that communicates with the higher capacity section B via front end opening 32 and front end 41 of the siren oscillator 40. The lower capacity section b provides an annular space S (see Figure 5) between the inner wall 62 (see Figure 6) of an opening 60 of the bottle unit 30 through which a fluid atomized doctor is sprayed and the front end 41 of the siren oscillator 40.
[0060] A lower capacity section b is formed so that liquid L (liquid LL in Figure 9) comes into contact with the vicinity of the atomizing part in a state where liquid L reaches the space S in the lower capacity b (see Figure 5). The lower capacity section b is formed so that the liquid LL reaches the atomizing part, even when the liquid LL (see Figure 9) is supplied to the space S in a small amount. In this structure, in the spray state (the inclined state shown in Figure 9) the liquid spray apparatus 100 (see Figure 1) is tilted towards the siren oscillator 40. The liquid LL (see Figure 9) flowing from the section of higher capacity B of the bottle unit 31 for the lower capacity section b adheres to the circumference and surface 42 of the front end 41 of the siren oscillator 40.
[0061] The space between the inner wall 62 of the front end 41 of the siren oscillator 10 forming space S can be adjusted so that the liquid LL (in the lower capacity section b) is supplied to the vicinity of the atomizing part by the surface tension between the mesh member 1 and the front end 41, when the amount of liquid L in the section with the highest capacity B is reduced to a minimum amount just before finishing.
[0062] The bottle part 31 is formed so that the liquid LL in the higher capacity section B and the liquid LL in the lower capacity section b are separated, when the liquid L in the higher capacity section B is reduced below of a certain amount in a temporarily placed orientation (for example, in the horizontal state, shown in Figure 7) different from the normal spraying time (inclined state in Figure 9). The lower capacity section b is in a higher position than the higher capacity section B. Therefore, in the event that liquid L does not completely fill the higher capacity section B and the liquid surface is under the opening of the front end 32, only a small amount of liquid LL in the lower capacity section b remains around the front end 41 of the siren oscillator 40, while the other liquid L is stored in the largest section capacity B.
[0063] It should be noted that in the state in which the box 35 is attached to the bottle part 31 and the outer mesh box 55 and an inner mesh box 57, as will be described later, are affixed to the opening 60, the inner part of the bottle part 31 is kept liquid-proof, except for an orifice for introducing external air (not shown) formed in box 35. SIREN OSCILLATOR 40
[0064] Referring to Figures 5 and 6, as described above, the siren oscillator 40 is arranged so as to be positioned opposite the front end opening 32 of the bottle part 31. The siren oscillator is it is located under the opening 60 provided in the bottle unit 30. Above the siren oscillator 40, the outer mesh box 55 and the inner mesh box 57, as described below, are attached to the opening 60 in a detachable manner. SUPPORT MEMBERS 50 AND 52
[0065] Referring to Figures 7 and 8 (and 3 to 5), the support members 50 and 52 are configured so that they can be adjusted with the interposed mesh member 1. The mesh member 1 is held between the support members 50 and 52 adjusted together, above the front end 41 of the siren oscillator 40. The support members 50 and 52 support the mesh member 1 with each other, and secure mesh member 1 so that mesh member 1 covers the surface of the siren oscillator 40.
[0066] Sealing Support Set 51, Internal Mesh Box 57, and External Mesh Box 55
[0067] The support members 50 and 52 adjusted together are fixed to the internal circumference of the sealing support set 51, with an annular shape. The support members 50 and 52 adjusted together are attached to the inner mesh box 57 by means of the sealing support assembly 51. The outer circumference of the sealing support assembly 51 is fitted to the inner mesh box 57. One air space between the support members 50, 52 and inner mesh box 57 is sealed by the sealing support assembly 51.
[0068] The inner mesh box 57 is affixed around the opening 60 in order to cover the opening 60 provided in the bottle unit 30. The inner mesh box 57 comprises support parts 57T pivotally supported by support parts 38T provided on the side of the bottle part 31. The outer mesh box 55 is provided so as to externally cover the inner mesh box 57.
[0069] With the inner mesh box 57 affixed around the opening 60, an air gap formed between the inner mesh box 57 and openings 50 is sealed by sealing support set 57. This sealing prevents the liquid L LL stored in the bottle part 31 leaks from the bottle part 31. Therefore, even with the liquid spraying device 100 tilted, the liquid L and liquid LL in the bottle part 31 do not leak out.
[0070] Here, it is necessary to keep the mesh member 1 in contact with the surface 42 of the front end 41 of the signal oscillator 40 with an appropriate force. The contact pressure of the mesh member 1 against the surface 42 can vary with the dimensional variations found in each component, which run during the manufacture, variations that occur when assembling the respective components or similar.
[0071] In the liquid spraying apparatus 10 according to the present embodiment, the support members 50, 52 which fix the mesh member 1 between them, are supported by a seal support assembly 51. Once the member of mesh 11 coming into contact with the surface 42 of the front end 41 of the siren oscillator 40, with the sealing support assembly 51 interposed between them, the variations mentioned above are absorbed by the elasticity of the sealing support assembly 51 itself. therefore, in the liquid spraying apparatus 100 a stable zi1 ratio can be maintained between the mesh member 1 and the surface 42 of the front end 41.
[0072] As described above, the support parts 57T of the inner mesh box 57 are pivotally supported by support parts 38T provided on the side of the bottle part 31. With this structure, the inner mesh box 57 is the one fixed to the opening 60 of detachable way with mesh member 1, support members 50, 52, and sealing support assembly 51 integrally attached to the inner part of the inner mesh box 57.
[0073] Once the mesh member 1 is attached to the inner mesh box 57, the mesh member 1 can be washed easily by removing the inner mesh box 57 from opening 6 (by rotating the inner mesh box 57) . OPERATING THE LIQUID SPRAYING DEVICE 100
[0074] In the state in which the liquid spraying apparatus 100 with the bottle unit 30 attached to the body part 20 (see Figure 1) is placed on a platform or similar, the bottle unit 30 is oriented horizontally and the liquid L in the bottle part 31 is collected at the bottom of the bottle part 31, as shown in Figure 7.
[0075] When the liquid spraying apparatus 100 is supported by hands and tilted towards the siren oscillator 40, the bottle unit 30 tilts, as shown in Figure 9, so that the higher capacity section B from the bottle part 31 flows into the space S in the section with the lowest capacity b via the front end opening 32. The liquid LL in the space S reaches the vicinity of the contact part between the surface 42 of the front end 41 and the limb mesh 1 on the outside of the front end 41 of the siren oscillator 40.
[0076] If the energy breaker 21 (see Figure 1) of the bottle part 20 is in this state, the siren oscillator 40 vibrates ultrasonically. The liquid LL is discharged through the micropores of the mesh member 1 by ultrasonic vibrations of the mesh member 1 and surface 42 of the front end 41 of the siren oscillator 40, so that the atomized liquid LL is sprayed through the opening 60 ( see Figures 3 to 5). In the liquid spraying apparatus 100, according to the present embodiment, a recess 43 (which will be described in more detail below) is formed on the surface 42 of the front end 41. Therefore, during spraying, the liquid L (liquid LL) is stably supplied, in a small amount, from the lower capacity section b to the mesh member1.
[0077] Even when the amount of liquid L in the higher capacity section B of the bottle part 31 is reduced to a small amount (see Figure 9), the liquid LL in the lower capacity section b can be raised to the atomizing part by surface tension between the front end 41 of the siren oscillator 40 and the inner wall 62 (see Figure 6), as described above, to be supplied additionally to the mesh member 1 by vibrations from the siren oscillator 40.
[0078] On the other hand, in a state different from the time of normal use (for example, in the case of temporarily interrupting the spraying operation or placing the liquid spraying device 100 on the platform, etc.), the liquid L adheres slightly to the inner wall 62 of the lower capacity section b and most of the liquid L is stored in the higher capacity section B except when the higher capacity section of the bottle part 31 is almost full of liquid L. The liquid L it is preventing it from being consumed uselessly, even when the power breaker is on. In combination with the auto-off function when liquid L runs out, it can also prevent the battery from being consumed uselessly.
[0079] Furthermore, liquid L is not supplied to the contact part between the surface 42 of the front end 41 of the siren oscillator 40 and the mesh member 1, except in normal spraying (when it is in the horizontal state shown in Figure 7). Once the liquid L is not supplied to the mesh member 1, there is no leakage of the liquid L. The liquid L and liquid LL in the bottle part 31 do not leak out. SIREN OSCILLATOR 40
[0080] Here, referring to Figures 10 to 14, the siren oscillator 40 used in the liquid spraying apparatus 100 (see Figure 1) according to the present embodiment will be described in detail. Figure 10 is a plan view of the siren oscillator 40 according to the present embodiment. Figure 11 is a plan view showing the siren oscillator 40. Figure 12 is a side view of around surface 42 of the front end 41 of the siren oscillator 40. Figure 13 is a cross-sectional view taken along line XIII-XIII in Figure 12. Figure 14 is a cross-sectional view showing the state of the siren oscillator 40 at the time of spraying.
[0081] As shown in Figures 10 to 14, the surface 42 of the siren oscillator 40 is provided with recess 43 extending like a groove in a substantially diametrical direction of the surface 42. The siren oscillator 40 can be fixed with the phase in the rotational direction and positioned so that the recess 43 extends in a direction in which the liquid spraying apparatus 100 is tilted towards the siren oscillator 40.
[0082] The recess 43, according to the present embodiment, has a first end 43A and a second end 43b. The first end 43A and the second end 43b are each opposite in the direction in which the recess 43 extends. The second end 43b is located on the opposite side of the first end 43A. The recess 43, according to the present embodiment, is formed so that it extends so that the first end 43A and the second end 43b both reach the outer circumferential surface of the front end 41.
[0083] As shown in Figure 11, the surface 42 of the front end 41 of the siren oscillator 40 according to the present embodiment is circular in shape. The surface 42 has a diameter of about 3.5 mm, for example. A width 43D in the perpendicular direction (horizontal direction in the drawing sheet in Figure 11) to the direction in which the recess 43 extends (vertical direction in the drawing sheet in Figure 11) is about 11.0 mm, for example. The width 43D is preferably greater than or equal to 5% and less than or equal to 50% of the diameter of the surface 42. If the width 43D of the recess; 43 is excessively large (if the surface 42 is sufficiently reduced in area) an unstable spray state may occur, and favorable spraying may not be achieved. On the other hand, if the recess width 43D is excessively small, the essential effect of recess 43 may not be obtained. Therefore, the width 43D is preferably greater than or equal to 5% and less than or equal to 50% of the surface diameter 42.
[0084] Referring to Figures 12 and 13, recess 43 has depth 43H from surface 42 of about 0.1 mm, for example. The 43H depth is preferably greater than or equal to 0.03 mm and less than or equal to 1.0 mm. If the 43H depth value does not fall within this range, an unstable spray state occurs, and favorable spraying may not be achieved. If the width of the recess 43 is narrow and the depth 43H is too deep, this may be undesirable in terms of cleanliness. On the other hand, if the depth 43H of recess 43 is excessively shallow, the essential effect of recess 43 may not be achieved. Therefore, the depth 43H is preferably greater than or equal to 0.03 mm and less than or equal to 1.0 mm. The bottom surface 43c of the recess 43 is rougher than the surface of the surface 42 (surface roughness of the bottom 43> surface roughness of the surface 42).
[0085] Referring to Figure 13, the outer edge of the surface 42 of the front end 41 of the siren oscillator 40 has been subjected to a chamfering operation R, which chamfer R has a predetermined processing radius 41R (dimension the chamfer). The processing radius 41R is greater than 0.1 mm (R 0.1 mm), being about 0.2 mm, for example.
[0086] The depth 43H of the recess 43 from the surface 42 of the front end 41 is preferably provided to be less than the processing radius 41R. In the case where the recess 43 is formed using a cutting tool or the like, burrs can be formed at the first end 43A or second end 43b of the recess 43. In the case where the outer edge of the surface 42 undergoes a forming operation chamfering after the formation of recess 43, burrs can be removed because the depth of 43H of recess 43 from the surface 42 of the front end 41 is formed less than the processing radius 41R.
[0087] The outer edge of the surface 42 of the front end 42 of the siren oscillator 40 is not limited to the chamfering operation, but can undergo a chamfering operation, providing a predetermined chamfering dimension. Also, in this case, the chamfer dimension is greater than 0.1 mm (C 0.1 mm), and preferably about 0.2 mm, for example. With this structure, the mentioned strokes can also be removed.
[0088] Referring to Figure 14, providing the recess 43 on the surface 42 of the front end 41 of the siren oscillator 40, a space corresponding to the shape of the recess 43 is formed between the mesh member 1 and surface 42. As described above, liquid L (liquid LL) is supplied from the bottle part 31 towards the siren oscillator 40. Liquid L (liquid LL) is supplied from the outside of the front end 41 from the siren oscillator 40 to the surface 42 of the front end 41.
[0089] In addition, liquid L (liquid LL) is supplied from the outside of the front end 41 to a front end position of the surface 42 of the front end 41 of the siren oscillator 40 and mesh member 1. At this moment , the liquid L (liquid LL) can also reach the lower surface of the mesh member 1, while flowing from the outside of the front end 41 to the space created by the recess 43 (see arrow AR in Figure 14).
[0090] Liquid L is collected in recess 43. The amount of liquid L (liquid LL) supplied for mesh member 1 is locally increased between mesh member 1 and surface 42 with recess 43 in the surface 42. Liquid L (liquid LL) can be supplied stably to mesh member 1.
[0091] The power circuit breaker 21 of the body part 20 (see Figure 1) goes into a state in which the liquid L (liquid LL) is steadily supplied to the mesh member 1. The siren oscillator 40 vibrates ultrasonically and the liquid LL, in the lower capacity section b, is supplied to the mesh member 11 by ultrasonic vibrations of the mesh member 1 and surface 42 of the front end 41 of the siren oscillator 40. The liquid LL is discharged from the micropores of the mesh member 1 and sprayed through openings 60. During spraying, liquid L (liquid LL) is reliably supplied in small quantity to mesh member 1 through recess 43.
[0092] Liquid L (liquid LL) is supplied in a stable manner to the mesh member 1 without interruption. Therefore, the liquid spraying apparatus 100, according to the present embodiment, can steadily spray liquid L (liquid LL).
[0093] Furthermore, when the recess 43 of the siren oscillator 40 extends in the direction in which the liquid spraying apparatus 10 is tilted towards the siren oscillator 40 (state shown in Figure 14), the liquid L (liquid LL) it can be supplied more stably to the mesh member 1 without interruption.
[0094] In the case where the recess 43 is provided in the center of the surface 42, the vibrational energy of the siren oscillator 40 is concentrated in the center of the surface 42. Therefore, a continuous spray state can be achieved from more stable way.
[0095] The recess 43 according to the present embodiment is provided so as to extend so that the first end 43A and the second end 43b reach the outer circumferential surface of the front end 41. Once both ends of the recess 43, it prevents the liquid L from being supplied in excess to the mesh member 1. SECOND ACHIEVEMENT
[0096] Referring to Figures 15 to 17, a liquid spraying apparatus, according to the present embodiment, will be described. Here, the difference from the liquid spraying apparatus 100 (see Figure 1) from the first embodiment, described above, will be described.
[0097] As shown in Figure 15, providing recess 43 on the surface 42, four corners P are formed on the surface 42 of the siren oscillator 40. Even if the outer edge of the surface 42 of the front end 41 does not suffer chamfering operation, four corners P are formed in a similar way.
[0098] Assuming that the mesh member 1 touches the surface 42, in parallel with the surface 42 of the front end 41 of the siren oscillator 40. In this case, the mesh member 1 receives a local voltage from the four corners P by ultrasonic vibrations with the surface 42 of the front end 41, so that portions of the mesh member 1 contacting the corners are likely to be damaged.
[0099] Figure 16 is a plan view showing a siren oscillator 40 used in the liquid spraying apparatus according to the present embodiment. Figure 17 is a cross-sectional view taken along line XVII-XVII in Figure 16.
[00100] Referring to Figures 16 and 17, in the present embodiment, the mesh member 1 is attached in an inclined manner at a predetermined angle θ1 (see Figure 17) to the surface 42 of the front end 41 of the oscillator siren 40. With this structure, the number of portions of mesh 1 member that contact the corners P is reduced to two. The number of portions of mesh member 1 to be damaged is reduced, and the likelihood of mesh member 1 being damaged can be reduced. THIRD ACHIEVEMENT
[00101] Referring to Figures 18 and 19, a liquid spray apparatus according to the present embodiment will be described. Here, a difference from the liquid spray apparatus (Figures 16, 17) from the second embodiment, described above, will be described.
[00102] Referring to Figures 18 and 19, the mesh member 1 is affixed to the surface 42 of the front end 41 of the signal oscillator 40 in an inclined manner at a predetermined angle θ1 (see Figure 19). In other words, the mesh member 1 is attached at an angle in the direction of the arrow DR1.
[00103] As shown in Figure 18, in the present embodiment, in a projection in which the mesh member 11 is projected at the front end 431 side of the siren oscillator 40, the mesh member 1 is affixed to the surface 42 of the end front 41 of the siren oscillator 40, so that the direction in which the mesh member 1 is inclined (direction of arrow DR1) and the direction in which recess 43 extends direction of arrow DR2) intersect.
[00104] That is, in the projection mentioned above, a predetermined angle θ2 is provided between the direction in which the mesh member 1 is inclined (direction of the arrow DR1) and the direction in which the recess 43 extends (direction of the arrow DR2).
[00105] With this structure, the mesh member 1 does not contact the corners P, but come in contact with the surface 42 of the front end 41 at the edges R outside the corners P. The probability of the mesh member 1 being damaged can be additionally reduced. FOURTH ACHIEVEMENT
[00106] Referring to Figure 20, a liquid spray apparatus, according to the present embodiment, will be described. A 40A siren oscillator is used in the liquid spray apparatus according to the present embodiment. In the siren oscillator 40A, a recess 43A is provided on the surface 42 of the front end 40.
[00107] The recess 43A according to the present embodiment is formed so that the first end 43a reaches the outer circular surface of the front end 41. The second end 43b does not reach the outer circumferential surface of the front end 41. When the recess 43A is not provided at the cross surface 42, as in the present embodiment, the liquid L supplied to surface 42 can be stored in recess 43A.
[00108] Because liquid L is stored in recess 43A, liquid L can be supplied in a stable manner to mesh member 1 without interruption. As a result, liquid L can be sprayed stably.
[00109] By applying the structure of the second or third embodiments, described above, to the structure of the fourth embodiment, the probability that the mesh member 1 will be damaged can be reduced. FIFTH ACHIEVEMENT
[00110] Referring to Figure 21, a liquid spray apparatus according to the present embodiment will be described. A 40B siren oscillator is used in the liquid spray apparatus according to the present embodiment. In the siren oscillator 10B a recess 43B is provided on the surface 42 of the front end 41. The recess 43B is determined to be depressed hemispherically on the surface 42 of the front end 41. In this case, the liquid L supplied on the surface 2 can also be stored in recess 43B similarly to the fourth embodiment described above.
[00111] Because liquid L is stored in recess 43B, liquid L can be supplied in a stable manner to mesh member 1 without interruption. As a result, liquid L can be sprayed stably. VARIATION OF THE FIFTH ACHIEVEMENT
[00112] Referring to Figure 22, in the state in which the liquid spraying apparatus according to the present variation is inclined towards the siren oscillator 20, the recess 43B can be provided to be positioned in the direction of gravity on the surface 42 of the front end 41 of the siren oscillator 40. With this structure, liquid L should probably be collected in recess 43B.
[00113] Because liquid L is stored in recess 43B, liquid L can be supplied in a stable manner to mesh member 1 without interruption. As a result, liquid L can be sprayed stably. SIXTH CONCRETE
[00114] Figure 23 is a perspective view showing a liquid spraying device 200, according to the present embodiment. Here, the difference from the first embodiment described above will be described. An outer mesh box 55 in the present embodiment is configured to be detachable from the bottle part 31 and affixed to the bottle part 31 without being positioned (the outer mesh box 55 is fixed at any angle in the direction of the DR arrow).
[00115] The mesh member 1 secured by the outer mesh box 55 becomes rotatable in relation to the siren oscillator 40, the state being that the mesh member 1 and the surface 42 (not shown) of the front end 41 ( not shown) of the siren oscillator 40 (not shown) if topam is maintained.
[00116] For example, supposing that a user removes outer mesh box 55 from bottle part 31, together with mesh member 1 and cleans mesh member 1. The user fixes mesh member 1, so new, in the bottle part 31, together with the outer mesh box 55. The outer mesh box 55 is affixed to the bottle part 11 without being positioned in the direction of rotation (fixed in any phase).
[00117] The state in which the mesh member 1 is attached to the siren oscillator 40 (not shown) is determined to change each time the outer mesh box is affixed / detached. With this structure, the orientation in which the surface 42 (not shown) of the siren oscillator 40 touches the mesh member 1 is set to change each time. Once the position, where mesh member 1 and recess 43 (not shown) meet, is determined to change each time (load concentration on mesh member 1 being restricted), the probability of the member mesh 1 being damaged can be reduced.
[00118] Although the respective embodiments have been described above detailed in the present invention the respective embodiments described above are merely illustrative and in no way restrictive. For example, a plurality of recesses 43, 43A and 43 B can be provided. The surface 42 of the front end 41 of the siren oscillator 40 can be configured so that a liquid is supplied to it without tilting the liquid spraying apparatus 100.
[00119] Therefore, the technical scope of the present invention will be shown by the appended claims and that including any modifications encompassed in the spirit and scope equivalent to the claims.
