Description

TECHNICAL FIELD

[0002] The atomization device refers to a device for heating atomized liquid to form an aerosol by atomizing the atomized liquid. The aerosol formed by atomizing the atomized liquid can be used for a user to smoke.

The base is connected to the shell assembly, and the base is provided with an air inlet through hole communicating with the atomization cavity. In operation, external gas can flow into the atomization cavity through the air inlet through hole of the base. The atomized liquid in the shell assembly can be conducted into the atomization cavity and atomized to form an aerosol under the heating action of the atomization core.

[0043] The following will be described in detail in combination with specific drawings and embodiments:

[0044] Please see Figures 1 to 4 , Figure 1 The perspective view of the atomization device provided for some embodiments of the present application, Figure 2 The Figure 1 sectional view along A-A, Figure 3 The Figure 2 enlarged view of a part, Figure 4 The perspective view of the base 20 of the shell structure 100 provided for some embodiments of the present application. The shell structure 100 provided by the embodiments of the present application is applied to an atomization device. The atomization device comprises a shell structure 100 and an atomization core 200, and the shell structure 100 is used in cooperation with the atomization core 200. Specifically, at least part of the atomization core 200 is arranged in the shell structure 100. The shell structure 100 provided by the embodiments of the present application comprises a shell assembly 10 and a base 20. The shell assembly 10 is provided with an atomization cavity 101. The base 20 is connected to the shell assembly 10, and the base 20 is provided with a first air inlet through hole 201 along a first direction Y. The first air inlet through hole 201 is distributed along the first direction Y with the atomization cavity 101, and the first air inlet through hole 201 and the atomization cavity 101 communicate with each other. Along the first direction Y, the side of the base 20 close to the atomization cavity 101 is provided with a first surface 202. Along the first direction Y, the first surface 202 is an arc surface arranged protruding towards the atomization cavity 101, and the first air inlet through hole 201 penetrates the first surface 202.

[0045] The shell assembly 10 is the main structure of the shell structure 100. The atomization cavity 101 is a chamber arranged in the shell assembly 10, used for mounting the atomization core 200. Specifically, at least part of the atomization core 200 is mounted in the atomization cavity 101.

[0046] The first air inlet through hole 201 penetrates the base 20 along the first direction Y, and refers to opposite sides of the first air inlet through hole 201 penetrating the base 20 along the first direction Y. The base 20 is arranged at one end of the shell assembly 10 along the first direction Y, so that the first air inlet through hole 201 and the atomization cavity 101 are distributed along the first direction Y. Among them, one end of the first air inlet through hole 201 along the first direction Y is communicated with the atomization cavity 101, and the other end is used for communicating with the external environment.

[0047] The first surface 202 is a side surface of the base 20 close to the atomization cavity 101 along the first direction Y, specifically, a surface provided with the first air inlet through hole 201.

[0048] As shown in Figure 2 , the shell assembly 10 can also be provided with a liquid storage bin 102 and a mist outlet passage 103. Among them, the liquid storage bin 102 is used for storing atomized liquid, and the liquid storage bin 102 is communicated with the atomization cavity 101. Among them, the mist outlet passage 103 is communicated with the atomization cavity 101, and is used for communicating with the external environment. Specifically, as Figure 2 , the atomization cavity 101 and the mist outlet passage 103 are distributed and communicated along the first direction Y. Based on this, external gas can flow into the atomization cavity 101 through the first air inlet through hole 201, and the atomized liquid in the liquid storage bin 102 can be conducted to the atomization core 200 in the atomization cavity 101, and atomized to form an aerosol under the heating action of the atomization core 200. The aerosol flows to the outside of the shell assembly 10 through the mist outlet passage 103 with the gas in the atomization cavity 101, realizing the effect of misting.

[0049] The shell structure 100 provided by the embodiment of the application, the base 20 is provided with the first air inlet through hole 201 communicated with the atomization cavity 101 along the first direction Y, the base 20 is provided with the first surface 202 on the side close to the atomization cavity 101, the first surface 202 is an arc surface arranged protruding towards the atomization cavity 101, and the first air inlet through hole 201 penetrates the first surface 202, so that when the atomized liquid in the atomization cavity 101 accidentally flows towards the base 20, the atomized liquid is easy to slide along the first surface 202, and is not easy to leak through the first air inlet through hole 201. Therefore, the risk of atomized liquid leakage can be reduced.

[0050] In some embodiments, please refer to Figure 2 , and combine with other drawings. The atomization core 200 can include a liquid guide cotton 210 and a heating element 220 arranged on the liquid guide cotton 210, and at least part of the liquid guide cotton 210 and at least part of the heating element 220 can be arranged in the atomization cavity 101. The atomized liquid can be conducted to the liquid guide cotton 210 in the atomization cavity 101, and conducted to the heating element 220 under the capillary action of the liquid guide cotton 210, so as to be atomized to form an aerosol under the heating action of the heating element 220. Among them, the heating element 220 can heat under the condition of being electrified, so as to heat the atomized liquid.

[0051] In some embodiments, reference is made to Figure 4 , and in conjunction with other drawings. The base 20 is provided with a plurality of first air inlet through holes 201, which are arranged on the base 20 at intervals.

[0052] In this way, the efficiency of the flow of external gas into the atomization cavity 101 can be improved, thereby helping to improve the atomization efficiency of the atomization device formed by the bracket structure.

[0053] In some embodiments, reference is made to Figures 2 to 4 , and in conjunction with other drawings. The first surface 202 is a spherical surface.

[0054] It can be understood that the first surface 202 is spherical. Among them, the first surface 202 can be one part of the outer surface of the spherical structure, for example, it can be 1 / 2, 1 / 3, 1 / 4, etc. of the surface of the spherical structure.

[0055] As an example, as shown in Figure 4 , the first surface 202 is a hemispherical surface.

[0056] In this way, the smoothness of the first surface 202 can be improved, which is convenient for guiding the atomized liquid to slide when the atomized liquid accidentally flows towards the base 20, so that the atomized liquid flows to the outer periphery of the first surface 202 and is not easy to leak through the first air inlet through hole 201, thereby helping to reduce the risk of leakage of the atomized liquid.

[0057] In some embodiments, reference is made to Figures 2 to 4 , and in conjunction with other drawings. The base 20 includes a seat body 21 and an air inlet part 22. The seat body 21 is connected to the shell assembly 10 and is connected to the outer periphery of the air inlet part 22. The seat body 21 is provided with a first wall 204 on the side facing the atomization cavity 101 along the first direction Y. The first air inlet through hole 201 penetrates the air inlet part 22 along the first direction Y, and the air inlet part 22 is provided with a second wall 205 and a first surface 202. Along the first direction Y, the second wall 205 is connected between the first wall 204 and the first surface 202.

[0058] The seat body 21 is the main part of the base 20. Among them, the seat body 21 is connected to one end of the shell along the first direction Y.

[0059] The air inlet part 22 is a structure of the base 20 for the gas in the external environment to enter the atomization cavity 101, that is, the air inlet part 22 is a structure of the base 20 for arranging the first air inlet through hole 201.

[0060] The first wall 204 is the side surface of the seat body 21 facing the atomization cavity 101 in the first direction Y.

[0061] The second wall 205 and the first surface 202 are surfaces of the air inlet portion 22, and the first surface 202 is a side surface of the air inlet portion 22 facing the atomizing cavity 101 in the first direction Y.

[0062] It can be understood that, in the first direction Y, the air inlet portion 22 protrudes from the first wall 204 toward the atomizing cavity 101. Also, in the first direction Y, the second wall 205 is arranged between the first wall 204 and the first surface 202, and the second wall 205 is connected to the first wall 204 and the first surface 202.

[0063] Based on the above structure, when the atomizing liquid accidentally flows toward the base 20, the atomizing liquid can slide along the first surface 202 and the second wall 205 to the first wall 204 in sequence.

[0064] In this way, the first surface 202 is arranged to be higher than the first wall 204 in the direction of the base 20 facing the atomizing cavity 101 in the first direction Y. That is, the distance between the first surface 202 and the first wall 204 in the first direction Y is increased. In this way, the problem of the atomizing liquid flowing back to the first wall 204 and penetrating into the first air inlet through-hole 201 can be improved, thereby reducing the risk of leakage of the atomizing liquid.

[0065] In some embodiments, please refer to Figure 2 and Figure 3 together with other drawings. The base 20 is provided with a second surface 203 on the side facing away from the atomizing cavity 101 in the first direction Y. The second surface 203 is arranged to be recessed toward the first surface 202 to form an air inlet channel 206. The air inlet channel 206 is distributed along the first direction Y with the first air inlet through-hole 201 and is in communication.

[0066] The second surface 203 is a side surface of the base 20 facing away from the atomizing cavity 101 in the first direction Y, specifically a surface provided with the first air inlet through-hole 201. It can be understood that the first surface 202 and the second surface 203 are respectively arranged on opposite sides of the base 20 in the first direction Y.

[0067] Specifically, the second surface 203 is arranged on the side of the air inlet portion 22 of the base 20 facing away from the atomizing cavity 101 in the first direction Y, and is arranged to be recessed toward the first surface 202, thereby forming an air inlet channel 206 on the side of the air inlet portion 22 of the base 20 facing away from the atomizing cavity 101 in the first direction Y.

[0068] In this way, external gas can first enter the air inlet channel 206, and then flow into the atomizing cavity 101 through the first air inlet through-hole 201.

[0069] In some embodiments, please refer to Figures 2 to 4, and in combination with other drawings. The base 20 is provided with an air inlet cavity 207 on one side of the atomization cavity 101 along the first direction Y, and the air inlet cavity 207 is communicated with the first air inlet through hole 201. The shell structure 100 further comprises a sealing member 30, the sealing member 30 is sealed between the atomization cavity 101 and the air inlet cavity 207, and is provided with a second air inlet through hole 301, the second air inlet through hole 301 is communicated with the atomization cavity 101 and the air inlet cavity 207.

[0070] It can be understood that the seat body 21 and the air inlet part 22 surround to form the air inlet cavity 207.

[0071] The sealing member 30 refers to a part with sealing performance, which can be but is not limited to silicone, rubber and the like. Among them, the sealing member 30 is arranged between the shell assembly 10 and the seat body 21 of the base 20, so as to seal the atomization cavity 101 and seal the air inlet cavity 207.

[0072] The second air inlet through hole 301 penetrates the sealing member 30 along the first direction Y, so that the second air inlet through hole 301 is communicated with the atomization cavity 101 and the air inlet cavity 207.

[0073] In this way, external gas can flow into the air inlet cavity 207 through the first air inlet through hole 201, and flow into the atomization cavity 101 through the second air inlet through hole 301 under the buffering action of the air inlet cavity 207, so that the uniformity and stability of the mist can be improved. In addition, in the case that the atomization liquid accidentally flows from the atomization cavity 101 to the base 20 through the second air inlet through hole 301, the air inlet cavity 207 can receive and store the atomization liquid, thereby reducing the risk of atomization liquid leakage.

[0074] It needs to be pointed out here that the first direction Y is the approximate penetration direction of the first air inlet through hole 201, and is also the approximate distribution direction of the atomization cavity 101 and the first air inlet through hole 201.

[0075] As an example, the atomization device can have a height, a width and a thickness, the height of the atomization device is greater than the width of the atomization device, and the width of the atomization device is greater than the thickness of the atomization device. Among them, the first direction Y can be the height direction of the atomization device, the second direction Z can be the thickness direction of the atomization device, and the third direction X can be the width direction of the atomization device. Among them, the first direction Y and the second direction Z are perpendicular, the first direction Y and the third direction X are perpendicular, and the second direction Z and the third direction X are perpendicular.

[0076] In some embodiments, please refer to Figure 2 and Figure 3 , and in combination with other drawings. Along the first direction Y, at least part of the first air inlet through hole 201 is arranged staggered with the second air inlet through hole 301.

[0077] In the first direction Y, the first air inlet holes 201 are arranged to be staggered with the second air inlet holes 301, which means that the first air inlet holes 201 and the second air inlet holes 301 are not completely opposite to each other in the first direction Y. In some embodiments, the first air inlet holes 201 and the second air inlet holes 301 can be completely opposite to each other in the first direction Y, or a part of the first air inlet holes 201 and the second air inlet holes 301 are opposite to each other in the first direction Y, and the other part of the first air inlet holes 201 are not opposite to the second air inlet holes 301 in the first direction Y.

[0078] As an example, in the cross-sectional view of the atomization device perpendicular to the third direction X, as shown in Figure 2 and Figure 3 , at least a part of the first air inlet holes 201 protrude beyond the second air inlet holes 301 in the second direction Z, so that at least a part of the first air inlet holes 201 and the second air inlet holes 301 are not opposite to each other. In some embodiments, the first air inlet holes 201 and the second air inlet holes 301 can be distributed along the second direction Z, so that the first air inlet holes 201 and the second air inlet holes 301 are completely not opposite to each other in the first direction Y. Alternatively, as shown in Figure 2 and Figure 3 , a part of the first air inlet holes 201 and the second air inlet holes 301 are opposite to each other in the first direction Y, and the other part of the first air inlet holes 201 protrude beyond the second air inlet holes 301 in the second direction Z, so that the first air inlet holes 201 are not opposite to the second air inlet holes 301 in the first direction Y.

[0079] In this way, if the atomized liquid accidentally flows from the atomization cavity 101 to the base 20 through the second air inlet holes 301, the atomized liquid will not directly flow from the second air inlet holes 301 to the first air inlet holes 201, but will flow to the first surface 202 and slide along the first surface 202. In this way, the risk of leakage of the atomized liquid through the first air inlet holes 201 can be reduced.

[0080] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 , and in combination with other drawings. Among them, Figure 5 is a perspective view of the base 20 and the sealing member 30 of the shell structure 100 provided in some embodiments of the present application. The sealing member 30 includes a sealing body 31 and a sealing rib 32. The sealing body 31 is sealed between the atomization cavity 101 and the air inlet cavity 207, and is provided with the second air inlet holes 301 described above. The sealing rib 32 is arranged between the side of the sealing body 31 away from the air inlet cavity 207 in the first direction Y and the shell assembly 10, and the sealing rib 32 is arranged around the outer periphery of the second air inlet holes 301.

[0081] The sealing body 31 and the sealing rib 32 are two parts of the sealing member 30, both of which have sealing performance. Among them, the sealing rib 32 is a generally annular rib.

[0082] The sealing body 31 is sealed between the atomization cavity 101 and the air inlet cavity 207, that is, the sealing body 31 is arranged between the shell assembly 10 and the base 20, and seals the atomization cavity 101 and the air inlet cavity 207. The second air inlet through hole 301 penetrates the sealing body 31 along the first direction Y.

[0083] The sealing rib 32 is arranged on the side of the sealing body 31 away from the air inlet cavity 207 along the first direction Y, and abuts between the shell assembly 10 and the sealing body 31 along the first direction Y.

[0084] In this way, the sealing body 31 and the sealing rib 32 can seal between the shell assembly 10 and the base 20, and can improve the problem of leakage of atomized liquid through the gap between the shell assembly 10 and the base 20, thereby reducing the risk of liquid leakage.

[0085] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 , and combine with other drawings. The sealing piece 30 further includes a boss 33, which is arranged between the side of the sealing body 31 away from the air inlet cavity 207 along the first direction Y and the sealing rib 32, and is annularly arranged outside the second air inlet through hole 301.

[0086] Understandably, the sealing rib 32 is arranged higher relative to the sealing body 31 in the direction of the base 20 towards the atomization cavity 101 along the first direction Y. That is, the distance between the sealing rib 32 and the sealing body 31 along the first direction Y is increased. In this way, when the atomized liquid accidentally flows to the side of the sealing body 31 close to the atomization cavity 101 along the first direction Y, the boss 33 can block the atomized liquid, preventing the atomized liquid from flowing to the base 20 through the second air inlet through hole 301 and leaking through the first air inlet through hole 201.

[0087] Please refer to Figures 1 to 3 , and combine with other drawings. The atomization device provided in the embodiments of the present application includes a shell structure 100 and an atomization core 200, at least part of the atomization core 200 is arranged in the atomization cavity 101.
