[0050] Please refer to Figures 1 to 4 , wherein, Figure 1 the perspective view of the atomization device provided for some embodiments of the present application, Figure 2 for Figure 1 the sectional view along A-A, Figure 3 for Figure 1 the partial perspective view of the atomization device provided, Figure 4 the perspective view of the bracket 10 of the bracket structure 100 provided for some embodiments of the present application Figure 1 The bracket structure 100 provided by the embodiments of the present application is applied to the atomization device. The atomization device comprises the bracket structure 100 and the atomization core 200, and the bracket structure 100 is used in cooperation with the atomization core 200. Specifically, at least part of the atomization core 200 is arranged in the bracket structure 100. The bracket structure 100 provided by the embodiments of the present application comprises a bracket 10, which is provided with a liquid inlet through hole 102 and a mounting cavity 103 for mounting the atomization core 200. The mounting cavity 103 is provided with a first inner wall 1031, the liquid inlet through hole 102 penetrates the first inner wall 1031, and the first inner wall 1031 is provided with a liquid guide groove 106. The liquid guide groove 106 extends to the liquid inlet through hole 102 to communicate with the liquid inlet through hole 102.

[0051] The bracket 10 can be but is not limited to a plastic structure.

[0052] The first inner wall 1031 is the inner wall surface of the mounting cavity 103. The liquid inlet through hole 102 is a through hole, and the liquid inlet through hole 102 penetrates the first inner wall 1031, which means that the liquid inlet through hole 102 penetrates the solid wall where the first inner wall 1031 is located.

[0053] The liquid guide groove 106 is a groove provided on the first inner wall 1031, which is mainly used for guiding the atomization liquid.

[0054] The mounting cavity 103 is used for mounting the atomization core 200, and specifically, at least part of the atomization core 200 is arranged in the mounting cavity 103. Wherein, the atomization core 200 can abut against the first inner wall 1031, so that the atomization core 200 is arranged opposite to the liquid guide groove 106 and the liquid inlet through hole 102.

[0055] The bracket structure 100 provided by the embodiments of the present application is used for mounting the atomizing core 200 through the mounting cavity 103. The liquid inlet through hole 102 penetrates the first inner wall 1031 of the mounting cavity 103, and the first inner wall 1031 is provided with the liquid guide groove 106 extending to the liquid inlet through hole 102, so that the inner wall of the mounting cavity 103 used for abutting against the atomizing core 200 is provided with the liquid guide groove 106. In this way, the atomized liquid can flow to the liquid guide groove 106 through the liquid inlet through hole 102, and the positions of the atomizing core 200 opposite to the liquid inlet through hole 102 and the liquid guide groove 106 can all absorb and conduct the atomized liquid, so that multiple positions of the atomizing core 200 can simultaneously absorb and conduct the atomized liquid, which can improve the conduction efficiency of the atomized liquid, so that the atomized liquid can be continuously, stably and uniformly conducted. In this way, the problem of atomized liquid flow interruption can be improved, the risk of the atomizing core 200 being pasted can be reduced, and the atomization effect and atomization efficiency of the atomization device composed of the bracket structure 100 can be improved, so as to improve the use experience.

[0056] In some embodiments, please refer to Figure 2 and Figure 3 together with other drawings. The atomizing core 200 can include the liquid guide cotton 210 and the heating element 220. The heating element 220 is arranged on the liquid guide cotton 210, and both the liquid guide cotton 210 and the heating element 220 are arranged in the mounting cavity 103.

[0057] As an example, the liquid guide cotton 210 abuts against the first inner wall 1031, and the heating element 220 abuts against the side of the liquid guide cotton 210 away from the first inner wall 1031. Specifically, the liquid guide cotton 210 is opposite to the liquid inlet through hole 102 and the liquid guide groove 106.

[0058] In this way, the atomized liquid can be conducted to the liquid guide cotton 210 in the mounting cavity 103 through the liquid inlet through hole 102, and flow to the heating element 220 under the conduction of the liquid guide cotton 210, so as to be atomized to form aerosol under the heating action of the heating element 220.

[0059] In some embodiments, please refer to Figure 2 and Figure 3 together with other drawings. The atomizing core 200 can further include the electrode 230. The electrode 230 is connected to the heating element 220 and is used for supplying power to the heating element 220 under the action of an external power source, so that the heating element 220 generates heat under the action of electricity.

[0060] In some embodiments, please refer to Figure 4 together with other drawings. The liquid guide groove 106 includes a plurality of branch grooves 1061, and the plurality of branch grooves 1061 are arranged on the first inner wall 1031 in a spaced manner.

[0061] In some possible designs, as Figure 4As shown, and as will be described in greater detail below, the plurality of branch grooves 1061 extend to the liquid inlet through hole 102, such that the liquid inlet through hole 102 can communicate with the plurality of branch grooves 1061. In this way, the atomized liquid in the liquid inlet through hole 102 can flow into the plurality of branch grooves 1061.

[0062] In some possible designs, as shown in Figure 4 As shown, and as will be described in greater detail below, the plurality of branch grooves 1061 extend to the liquid inlet through hole 102, such that the liquid inlet through hole 102 can communicate with the plurality of branch grooves 1061. In this way, the atomized liquid in the liquid inlet through hole 102 can flow into the plurality of branch grooves 1061.

[0063] As can be understood, at least one of the plurality of branch grooves 1061 extends to the liquid inlet through hole 102, such that the plurality of liquid inlet through holes 102 can all communicate with the corresponding branch grooves 1061. In this way, the atomized liquid in the plurality of liquid inlet through holes 102 can all flow into the corresponding branch grooves 1061.

[0064] By adopting the technical solutions described above, the liquid guide groove 106 includes the plurality of branch grooves 1061, so that the plurality of positions of the atomizing core 200 can simultaneously absorb and conduct the atomized liquid, which can improve the conduction efficiency of the atomized liquid, and the atomized liquid can be continuously, stably and uniformly conducted, which can reduce the risk of the atomizing core 200 being pasted, and can improve the atomization effect and atomization efficiency of the atomizing device formed by the support structure 100, thereby improving the use experience.

[0065] In some embodiments, as shown in Figure 4 , and as will be described in greater detail below, the liquid guide groove 106 can further include a communication groove 1062 arranged on the first inner wall 1031. The plurality of branch grooves 1061 all extend to the communication groove 1062, so that the plurality of branch grooves 1061 are communicated through the communication groove 1062.

[0066] The communication groove 1062 is a groove arranged on the first inner wall 1031.

[0067] In this way, on the one hand, the plurality of positions of the atomizing core 200 can simultaneously absorb and conduct the atomized liquid, which can improve the conduction efficiency of the atomized liquid. On the other hand, the plurality of branch grooves 1061 are communicated through the communication groove 1062, so that the atomized liquid can flow uniformly in the liquid guide groove 106, thereby improving the uniformity and stability of the atomized liquid conducted to the atomizing core 200.

[0068] In some embodiments, as shown in Figure 4 , and as will be described in greater detail below, the front projection of the liquid guide groove 106 is a mirror-symmetrical structure.

[0069] The front projection of the liquid guide groove 106 is the projection of the liquid guide groove 106 on the first inner wall 1031.

[0070] The projection of the liquid guide groove 106 is a mirror-symmetrical structure, so that the atomized liquid in the liquid guide groove 106 can be uniformly conducted into the atomizing core 200, which can improve the uniformity and stability of the atomized liquid, and is beneficial to improve the atomization effect of the atomization device formed by the support structure 100.

[0071] In some embodiments, please refer to Figure 4 , and the other drawings. The support 10 is provided with a plurality of spaced liquid inlet through holes 102, which include first through holes 102a and second through holes 102b. The projection area of the first through holes 102a is larger than that of the second through holes 102b, and the liquid guide groove 106 extends to the first through holes 102a.

[0072] It can be understood that at least one of the plurality of liquid inlet through holes 102 is the first through hole 102a, and at least one of the plurality of liquid inlet through holes 102 is the second through hole 102b.

[0073] The projection area of the first through hole 102a is the area of the projection of the first through hole 102a on the first inner wall 1031, and the projection area of the second through hole 102b is the area of the projection of the second through hole 102b on the first inner wall 1031.

[0074] By extending the liquid guide groove 106 to the first through hole 102a, and the projection area of the first through hole 102a being larger than that of the second through hole 102b, the atomized liquid can continuously flow from the first through hole 102a to the liquid guide groove 106, thereby improving the conduction efficiency of the atomized liquid and reducing the risk of paste core.

[0075] In some embodiments, please refer to Figures 2 to 7 , and the other drawings. Among them, Figure 5 is a perspective structure of the support 10 of the support structure 100 provided by some embodiments of the present application Figure 2 , Figure 6 is a perspective structure of the support 10 and the airway piece 20 of the support structure 100 provided by some embodiments of the present application, Figure 7 is Figure 6 a sectional view along B-B. The support 10 is also provided with a lower liquid groove 101 and an air exchange groove 104. The lower liquid groove 101 is communicated with the liquid inlet through hole 102, and the air exchange groove 104 is used to communicate with the lower liquid groove 101. The support structure 100 further includes an airway piece 20, at least part of which is arranged in the mounting cavity 103 and surrounded by the support 10 to form an atomization cavity 1001 and a gas guide channel 1002 communicated with the atomization cavity 1001. The gas guide channel 1002 is communicated with the air exchange groove 104, the atomization cavity 1001 is communicated with the liquid inlet through hole 102, and is used to mount the atomizing core 200.

[0076] The air passage member 20 can be, but is not limited to, a component with sealing performance such as silica gel or rubber.

[0077] The lower liquid groove 101 is used to accommodate the atomized liquid, and the atomized liquid is conducted to the liquid inlet through hole 102.

[0078] At least part of the air passage member 20 is installed in the installation cavity 103, and the bracket 10 is surrounded to form the atomization cavity 1001 and the air guide channel 1002 in the installation cavity 103.

[0079] The atomization cavity 1001 is used to install the atomization core 200, and is used for the atomized liquid to be atomized under the heating action of the atomization core 200. Specifically, external gas can enter the atomization cavity 1001, and the atomized liquid is atomized under the heating action of the atomization core 200 to form an aerosol in the atomization cavity 1001, which can flow to the outside of the atomization device with the gas in the atomization cavity 1001.

[0080] The liquid inlet through hole 102 is used to conduct the atomized liquid in the lower liquid groove 101 to the atomization core 200 in the atomization cavity 1001, and the air guide channel 1002 is used to communicate the atomization cavity 1001 and the air exchange groove 104.

[0081] Among them, the lower liquid groove 101 and the air exchange groove 104 are both grooves.

[0082] Through the lower liquid groove 101 connected to the liquid inlet through hole 102, the liquid inlet through hole 102 connected to the atomization cavity 1001, the atomization cavity 1001 connected to the air guide channel 1002, the air guide channel 1002 connected to the air exchange groove 104, the air exchange groove 104 used to communicate with the lower liquid groove 101, and the atomization cavity 1001 used to install the atomization core 200, so that the gas in the atomization cavity 1001 can flow to the lower liquid groove 101 through the air guide groove and the air exchange groove 104 in turn. In this way, the lower liquid groove 101, the liquid inlet through hole, the atomization cavity 1001, the air guide channel 1002, the air exchange groove 104 and the lower liquid groove 101 are sequentially connected, so that the gas can circulate inside the bracket structure 100, thereby improving the problem of negative pressure of the lower liquid groove 101, reducing the air pressure difference between the lower liquid groove 101 and the atomization cavity 1001, so that the air pressure inside the bracket structure 100 can tend to be more uniform, and the atomized liquid in the lower liquid groove 101 can be conducted to the atomization core 200 in the atomization cavity 1001 through the liquid inlet through hole 102. In this way, the conduction efficiency of the atomized liquid can be improved, the atomized liquid can flow to the atomization core 200 continuously and uniformly, the risk of the atomization core 200 being pasted can be reduced, the atomization efficiency and atomization effect of the atomization device composed of the bracket structure 100 can be improved, and the use performance and use experience can be improved.

[0083] In some embodiments, please refer to Figure 6, and in conjunction with other drawings. The number of the gas guiding channels 1002 is multiple, and the multiple gas guiding channels 1002 are arranged at intervals. The gas guiding channels 1002 extend to the liquid guiding groove 106 to communicate with the liquid guiding groove 106, so that the multiple gas guiding channels 1002 are communicated through the liquid guiding groove 106.

[0084] In this way, on the one hand, when the gas in the atomization cavity 1001 flows to the gas guiding channels 1002, the gas can flow uniformly into the multiple gas guiding channels 1002 through the liquid guiding groove 106 and flow to the lower liquid groove 101 through the gas exchange groove 104, so as to improve the gas exchange efficiency, improve the efficiency of pressure balance, and thus improve the conduction efficiency of the atomized liquid. On the other hand, when the atomized liquid in the lower liquid groove 101 accidentally flows to the gas guiding channels 1002 in sequence through the gas exchange groove 104, the atomized liquid can flow along the gas guiding channels 1002 to the liquid guiding groove 106 and be conducted to the atomization core 200.

[0085] As an example, the gas guiding channels 1002 extend to the communication groove 1062 of the liquid guiding groove 106.

[0086] In some embodiments, please refer to Figures 2 to 7 , and in conjunction with other drawings. The mounting cavity 103 is provided with the first inner wall 1031 on one side along the first direction Z, and is respectively provided with the second inner wall 1032 on opposite sides along the second direction X.

[0088] Specifically, the liquid inlet through hole 102 penetrates the solid wall where the first inner wall 1031 is located along the first direction Z.

[0089] The first direction Z and the second direction X intersect, which means that the first direction Z and the second direction X can form an included angle greater than 0° and less than 180°, that is, the first direction Z and the second direction X are not parallel. The first direction Z and the second direction X can be perpendicular to each other, or can not be perpendicular. The first direction Z and the second direction X can be directions intersecting on the same plane, or can be directions on planes respectively perpendicular to each other, and the projection of the second direction X on the plane where the first direction Z is located can intersect the first direction Z. Correspondingly, the meanings of the first direction Z and the third direction Y intersecting and the second direction X and the third direction Y intersecting can also be understood as explained above, which will not be repeated here.

[0090] As an example, the first direction Z and the second direction X are perpendicular, the first direction Z and the third direction Y are perpendicular, and the second direction X and the third direction Y are perpendicular.

[0091] 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. Wherein, the first direction Z can be the thickness of the atomization device, the second direction X can be the width of the atomization device, and the third direction Y can be the height of the atomization device.

[0092] In some possible designs, as shown in Figure 3 and Figure 4 , and in combination with other drawings. The second inner wall 1032 and the third inner wall 1033 are both provided with the first air guide groove 105. Alternatively, in other possible designs, among the second inner wall 1032 and the third inner wall 1033, only the second inner wall 1032 is provided with the first air guide groove 105. Alternatively, in still other possible designs, among the second inner wall 1032 and the third inner wall 1033, only the third inner wall 1033 is provided with the first air guide groove 105.

[0093] At least part of the air channel member 20 is arranged in the mounting cavity 103, and the air channel member 20 abuts against the second inner wall 1032 and the third inner wall 1033. The air channel member 20 and the first air guide groove 105 form the above-mentioned air guide channel 1002. Wherein, the first air guide groove 105 is a groove.

[0094] The air channel member 20 can form the above-mentioned atomization cavity 1001 together with the first inner wall 1031 and the second inner wall 1032. Alternatively, the air channel member 20 can form the above-mentioned atomization cavity 1001 together with the first inner wall 1031 and the third inner wall 1033. Alternatively, as shown in Figure 7 , the air channel member 20 can form the above-mentioned atomization cavity 1001 together with the first inner wall 1031, the second inner wall 1032 and the third inner wall 1033.

[0095] By adopting the technical scheme, the first air guide groove 105 is arranged on the inner wall in the installation cavity 103, and the air channel member 20 abuts against the inner wall of the installation cavity 103, so that the air guide channel 1002 is formed, the indirect communication between the air exchange groove 104 and the atomization cavity 1001 is realized, the air pressure difference between the atomization cavity 1001 and the lower liquid groove 101 is balanced, and the atomized liquid in the lower liquid groove 101 is conducted to the atomization core 200 in the atomization cavity 1001. In this way, the structure of the support structure 100 is very simple.

[0096] Specifically, the first air guide groove 105 extends to the liquid guide groove 106.

[0097] It should be noted that the gas in the atomization cavity 1001 can flow to the air guide channel 1002 through the liquid guide cotton 210, flow to the air guide channel 1002 through the mesh hole on the heating member 220, flow to the air guide channel 1002 through the gap between the air channel member 20 and the second inner wall 1032, and flow to the air guide channel 1002 through the gap between the air channel member 20 and the third inner wall 1033.

[0098] In some embodiments, please refer to Figure 3 and Figure 5 , and in combination with other drawings. In the direction of the first direction Z away from the first inner wall 1031, the first air guide groove 105 is gradually expanded.

[0099] Specifically, in the direction of the first direction Z away from the first inner wall 1031, the size of the first air guide groove 105 on the second inner wall 1032 in the third direction Y is gradually increased. In the direction of the first direction Z away from the first inner wall 1031, the size of the first air guide groove 105 on the third inner wall 1033 in the second direction X is gradually increased.

[0100] In this way, the gas can flow in the first direction Z away from the first inner wall 1031 in the air guide channel 1002 to flow to the air exchange groove 104, so that the air exchange efficiency can be improved, the efficiency of air pressure balance can be improved, and the conduction efficiency of the atomized liquid can be improved.

[0101] In some embodiments, please refer to Figure 2 , Figures 7 to 9 , and in combination with other drawings. Among them, Figure 8 is Figure 1 a partial perspective structure diagram of an atomization device provided by Figure 9A perspective view of the air passage 20 of the bracket structure 100 is provided for some embodiments of the present application. The air passage 20 includes a main body 21 and two pressing members 22. The main body 21 is arranged in the mounting cavity 103 and abuts against the second inner wall 1032 and the third inner wall 1033. The main body 21 and the first air guide groove 105 form the air guide passage 1002. The pressing members 22 are arranged on the side of the main body 21 close to the first inner wall 1031 along the first direction Z and are spaced apart from the first inner wall 1031 along the first direction Z. The two pressing members 22 are spaced apart along the second direction X and form the aerosol passage 10012. The main body 21, the pressing members 22, the first inner wall 1031, the second inner wall 1032, and the third inner wall 1033 form the atomization cavity 1001.

[0102] It can be understood that the main body 21, the pressing members 22, the first inner wall 1031, the second inner wall 1032, and the third inner wall 1033 form the atomization cavity 1001.

[0103] The pressing members 22 are arranged on the side of the main body 21 close to the first inner wall 1031 along the first direction Z and are spaced apart from the first inner wall 1031 along the first direction Z, so that the air passage 20 as a whole is spaced apart from the first inner wall 1031 along the first direction Z.

[0104] The atomization cavity 1001 can include a mounting space 10011 and the aerosol passage 10012, which are distributed and communicated along the first direction Z. The aerosol passage 10012 is communicated to the side of the mounting space 10011 away from the first inner wall 1031 along the first direction Z.

[0105] At least part of the atomization core 200 is arranged in the mounting space 10011. Specifically, the heating element 220 and the liquid guide cotton 210 of the atomization core 200 are arranged in the mounting space 10011, and specifically, the liquid guide cotton 210 abuts against the first inner wall 1031, and the heating element 220 abuts against the liquid guide cotton 210 and the pressing members 22 along the first direction Z.

[0106] It can be understood that the gas from the outside can enter the aerosol passage 10012, and the atomized liquid is atomized under the heating action of the atomization core 200 to form an aerosol in the aerosol passage 10012, which can flow to the outside of the atomization device along with the gas in the aerosol passage 10012.

[0107] The pressing member 22 is provided with a first groove 201 on the side away from the aerosol passage 10012 along the second direction X, and the first groove 201 penetrates through the side of the pressing member 22 close to the first inner wall 1031 along the first direction Z. The side of the main body 21 close to the first inner wall 1031 is provided with a second groove 202 at a position away from the aerosol passage 10012, and the second groove 202 is communicated to the first groove 201 and opposite and communicated to the first air guide groove 105.

[0108] By adopting the technical scheme, the gas in the gas mist channel 10012 can flow to the first groove 201 through the mesh hole on the heating element 220, and then flow to the gas guide channel 1002 through the second groove 202. In this way, the gas in the atomization cavity 1001 can flow to the gas guide channel 1002, so as to balance the gas pressure of the lower liquid tank 101 and the atomization cavity 1001, thereby improving the conduction efficiency of the atomized liquid.

[0109] In some embodiments, please refer to Figure 2 , Figure 7 and Figure 8 , and combine with other drawings. The electrode 230 of the atomization core 200 can be arranged on the side of the pressing member 22 away from the gas mist channel 10012 in the second direction X. In this way, the electrode 230 is arranged opposite to the first groove 201 and the second groove 202, respectively. By arranging the first groove 201 and the second groove 202, the problem that the electrode 230 blocks the gas flow between the gas mist channel 10012 and the gas guide channel 1002 can be solved.

[0110] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 , and combine with other drawings. The gas mist channel 10012 penetrates the airway member 20 in the third direction Y.

[0111] The mounting cavity 103 penetrates the support 10 on the side away from the third inner wall 1033 in the third direction Y, and the solid wall where the third inner wall 1033 is located is provided with the mist outlet channel 107 penetrating in the third direction Y.

[0112] The support structure 100 can further include a base structure 50 arranged at the end of the support 10 away from the third inner wall 1033 in the third direction Y. The base structure 50 is provided with the air inlet channel 501 which is communicated with the gas mist channel 10012.

[0113] In this way, the gas outside can flow into the gas mist channel 10012 through the air inlet channel 501. The atomized liquid is atomized into gas mist under the heating action of the atomization core 200, the gas mist flows with the gas in the gas mist channel 10012, and flows to the outside of the atomization device through the mist outlet channel 107.

[0114] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7 , and combine with other drawings. The airway member 20 is provided with the first surface 203 on the side away from the first inner wall 1031 in the first direction Z, the air exchange groove 104 extends to the first surface 203, and the first gas guide groove 105 extends beyond the first surface 203 in the first direction Z.

[0115] It can be understood that the first surface 203 is a side surface of the main body 21 away from the pressing member 22 along the first direction Z.

[0116] The first air guide groove 105 is beyond the first surface 203 along the first direction Z, which means that the first air guide groove 105 is beyond the first surface 203 along a direction away from the first inner wall 1031 in the first direction Z.

[0117] In this way, the gas in the air guide channel 1002 can flow to the first surface 203 along a direction away from the first inner wall 1031, and then flow to the air exchange groove 104 through the first surface 203 to flow into the lower liquid groove 101, thereby achieving the air exchange effect.

[0118] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7 , and combine with other drawings. The first surface 203 is provided with a third groove 204.

[0119] In this way, when the atomized liquid in the lower liquid groove 101 accidentally flows to the air exchange groove 104, the atomized liquid can flow to the first surface 203 and flow into the third groove 204, that is, the third groove 204 achieves the liquid storage effect. Of course, the airway member 20 can generate capillary force to absorb the atomized liquid.

[0120] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7 , and combine with other drawings. The airway member 20 further comprises a plurality of convex portions 23, which are arranged at intervals on the first surface 203.

[0121] In this way, when the atomized liquid in the lower liquid groove 101 accidentally flows to the air exchange groove 104, the atomized liquid can flow to the first surface 203, so that the convex portions 23 absorb the atomized liquid by capillary force, thereby achieving the liquid storage effect.

[0122] The bracket structure 100 further comprises a sealing member 30, which comprises a sealing body 31 and a flip piece 32. The sealing body 31 is sleeved outside the bracket 10 and the airway member 20, and the flip piece 32 is connected to the sealing body 31. The flip piece 32 covers one end of the air exchange groove 104 close to the lower liquid groove 101, and is used to flip relative to the sealing body 31 under the action of air pressure to make the lower liquid groove 101 and the air exchange groove 104 communicate.

[0123] Among them, the sealing body 31 and the flip piece 32 of the sealing member 30 can be but are not limited to silicone, rubber and other components with sealing performance.

[0124] It can be understood that the gas in the atomization cavity 1001 can flow to the air exchange groove 104 through the air guide channel 1002 and generate a certain pressure on the turnover piece 32. Thus, the turnover piece 32 can be turned away from the air exchange groove 104 under the action of the pressure, so that the air exchange groove 104 and the lower liquid groove 101 are communicated, and thus the gas in the air exchange groove 104 can flow into the lower liquid groove 101.

[0125] By covering the end of the air exchange groove 104 close to the lower liquid groove 101 with the turnover piece 32, the problem that the atomized liquid in the lower liquid groove 101 flows into the air exchange groove 104 can be improved.

[0126] In some embodiments, reference can be made to Figure 2 and Figure 11 together with other drawings. Among them, Figure 11 is Figure 1 a sectional view along C-C. The sealing body 31 can be sealed to the side of the airway piece 20 away from the first inner wall 1031 in the first direction Z and to the side of the bracket 10. Thus, the sealing body 31 can abut against the convex part 23 to form a communication channel 1003 between the sealing body 31 and the first surface 203, which is communicated with the air guide channel 1002 and the air exchange groove 104.

[0127] In some embodiments, reference can be made to Figure 2 and Figure 11 together with other drawings. The lower liquid groove 101 is arranged at the end of the bracket 10 close to the third inner wall 1033 in the third direction Y, and part of the lower liquid groove 101 is arranged at one side of the bracket 10 in the first direction Z, so that the lower liquid groove 101 is communicated with the liquid inlet through hole 102. The air exchange groove 104 is arranged at the side of the bracket 10 away from the lower liquid groove 101 in the first direction Z. The sealing body 31 is also sealed to one end of the bracket 10 in the first direction Z to cover the lower liquid groove 101. The sealing body 31 is provided with a lower liquid hole 301, which is communicated with the lower liquid groove 101. The sealing body 31 also covers the opposite sides of the bracket 10 in the first direction Z to cover the lower liquid groove 101 and the air exchange groove 104. It can be understood that the sealing body 31 is sleeved outside the bracket 10.

[0128] In some embodiments, reference can be made to Figure 10 and Figure 11, and in combination with other drawings. The support structure 100 can further include a mouthpiece 40, which includes a mouthpiece body 41 and a gas guide tube 42, the mouthpiece body 41 being connected to the outer periphery of the gas guide tube 42. The support 10, the airway piece 20 and the sealing piece 30 are all arranged in the mouthpiece body 41, and the base structure 50 is connected to the mouthpiece body 41. The gas guide tube 42 is mounted to the mist outlet channel 107 of the support 10, so that the gas guide tube 42 and the mist outlet channel 107 are in communication. The sealing body 31 surrounds the end of the support 10 away from the third direction Y, the mouthpiece body 41 and the gas guide tube 42 to form a liquid storage compartment 1004, and the liquid storage compartment 1004 and the liquid outlet hole 301 are in communication.

[0129] By adopting the technical scheme, when the atomization device is in use, external gas can flow into the gas mist channel 10012 through the air inlet channel 501 of the base structure 50, and the gas in the gas mist channel 10012 can flow into the gas guide channel 1002 and the air exchange groove 104 in turn, and then flow into the liquid outlet groove 101, so that the gas pressure of the liquid outlet groove 101 and the gas mist channel 10012 can be balanced to a certain extent. In this way, the atomized liquid in the liquid storage compartment 1004 can flow into the liquid outlet groove 101 through the liquid outlet hole 301, and then flow into the atomization core 200 in the atomization cavity 1001 through the liquid inlet through hole 102, and atomized to form gas mist under the heating action of the atomization core 200. The gas mist flows with the gas in the gas mist channel 10012, passes through the mist outlet channel 107 and the gas guide tube 42 in turn, and then flows out of the atomization device.
