[0045] In the related art, an atomization device generates an aerosol by heating an aerosol substrate; and by providing a liquid storage cavity in the atomization device, the liquid storage cavity is in communication with a provided atomization core, so that the aerosol substrate can be introduced into the atomization core, and the atomization core heats the aerosol substrate to generate an aerosol, thereby achieving the purpose of storing the aerosol substrate; however, since the atomization device itself has an air inlet and an air outlet, if the communication relationship between the liquid storage cavity and the atomization core is maintained, the aerosol substrate is likely to leak out through the air inlet or the air outlet during transportation of the atomization device, therefore, it is usually necessary to provide a blocking structure between the liquid storage cavity and the atomization core during transportation to avoid communication therebetween; although this way avoids leakage of the aerosol substrate, the user still needs to deliberately activate to communicate the liquid storage cavity and the atomization core when using, which undoubtedly increases the complexity of using the atomization device for the user, resulting in poor user experience.

After the aerosol substrate is heated to obtain an aerosol mixed with air, the air outlet 12 is used to discharge the aerosol. Therefore, the air inlet 11 and the air outlet 12 are both in communication with the internal cavity. In addition, based on the purpose of heating the aerosol substrate, the atomization core 6 is also arranged in the internal cavity.

[0048] Please refer to Figure 3In order to prevent the aerosol substrate from leaking directly through the air inlet 11 or the air outlet 12, the atomization device in the embodiment of the application further comprises a first isolation piece 2 and a second isolation piece 3, both of which are arranged in the internal cavity; the first isolation piece 2 divides the internal cavity into a liquid storage area 41 and a first area, the liquid storage area 41 serves as an area for storing the aerosol substrate, and the liquid storage area 41 and the first area are in communication through a liquid permeation hole 21 arranged on the first isolation piece 2, so that the aerosol substrate in the liquid storage area 41 can slowly flow into the first area through the liquid permeation hole 21.

[0049] The second isolation piece 3 is specifically arranged in the first area, and the second isolation piece 3 divides the first area into a buffer area 42 and an atomization area 43, the buffer area 42 is formed between the second isolation piece 3 and the first isolation piece 2, and the aerosol substrate in the liquid storage area 41 can enter the buffer area 42 through the liquid permeation hole 21; the atomization area 43 is formed on the side of the buffer area 42 away from the liquid storage area 41, and a liquid guide hole 31 arranged on the second isolation piece 3 can communicate the buffer area 42 and the atomization area 43, so that the aerosol substrate in the buffer area 42 can enter the atomization area 43 through the liquid guide hole 31.

[0051] In order to achieve the purpose of slowing down the entry of the aerosol substrate from the liquid storage area 41 into the atomization area 43, the atomization device in the embodiment of the application further comprises a buffer piece 5 arranged in the buffer area 42, the buffer piece 5 can absorb the aerosol substrate in the liquid storage area 41 entering the buffer area 42 through the liquid permeation hole 21, and guide the aerosol substrate into the atomization area 43. That is, the aerosol substrate in the liquid storage area 41 enters the buffer area 42 through the liquid permeation hole 21, and then the buffer piece 5 in the buffer area 42 absorbs the aerosol substrate, which can slow down the entry of the aerosol substrate into the atomization area 43; then, the aerosol substrate absorbed by the buffer piece 5 can enter the atomization area 43 through the liquid guide hole 31, so that the atomization area 43 can heat the aerosol substrate to generate aerosol, thus the atomization device in the embodiment of the application can avoid the leakage of the aerosol substrate, and does not need to isolate the liquid storage area 41 from the atomization core 6, effectively improving the user experience.

[0052] The buffer 5 in the embodiments of the present application is specifically a porous capillary member, which can absorb the aerosol substrate through capillary phenomenon to slow down the aerosol substrate from the liquid storage area 41 into the atomization area 43. Further, the material of the buffer 5 can be cotton or ceramic.

[0053] The atomization area 43 in the embodiments of the present application is connected to the air inlet 11 and the air outlet 12, serving as an area for heating treatment of the aerosol substrate, and the atomization core 6 is arranged in the atomization area 43; the structure of the atomization core 6 can include a heating member and a liquid guide member, the liquid guide member can guide and absorb the aerosol substrate in the buffer area 42, and the heating member can heat the aerosol substrate in the liquid guide member to generate aerosol. Specifically, the liquid guide member and the buffer 5 can have the same structure and material, that is, the liquid guide member is also a porous capillary member, and the material of the liquid guide member can be cotton or ceramic.

[0054] The internal cavity in the embodiments of the present application can have different division manners; for example, the first partition 2 and the second partition 3 are arranged side by side, which is equivalent to dividing the entire internal cavity into three areas in parallel according to the left-middle-right structure, which are respectively the liquid storage area 41, the buffer area 42 and the atomization area 43.

[0055] In addition, please refer to Figure 3 and Figure 4 In some optional embodiments, each area can also be arranged in a nested manner; wherein the first partition 2 specifically includes a first partition tube 20, the liquid storage area 41 is formed between the outer side of the tube wall of the first partition tube 20 and the inner wall of the shell assembly 1, and the first area is formed in the inner side of the tube wall of the first partition tube 20; the second partition 3 includes: a second partition tube 20 arranged in the inner side of the tube wall of the first partition tube 20, the buffer area 42 is formed between the first partition tube 20 and the second partition tube 30, and the atomization area 43 is formed in the inner side of the tube wall of the second partition tube 30.

[0056] The first partition 2 and the second partition 3 in the embodiments of the present application can both be tubular structures, and the inside and outside of the tubular structure can be divided into two areas; for the first partition tube 20, after the division of the tube wall, the outside of the first partition tube 20 forms the liquid storage area 41, and the inside of the first partition tube 20 forms the first area; the second partition tube 30 arranged in the first area, after the division of the tube wall, the outside of the second partition tube 30 forms the buffer area 42, and the inside of the second partition tube 30 forms the atomization area 43. Since the first partition tube 20 and the second partition tube 30 are arranged in a nested manner, the areas formed are also nested and uniformly distributed, which can fully adapt to the overall cylindrical atomization device, and the atomization area 43 is located at the center.

[0057] In some optional embodiments, please refer toFigure 5 and Figure 6 In order to ensure the utilization rate of the aerosol substrate, the liquid permeation hole 21 penetrates the wall of the first isolation pipe 20, and is arranged at the end close to the air inlet 11; the liquid guide hole 31 penetrates the wall of the second isolation pipe 30, and is arranged at the end close to the air inlet 11. That is, the liquid permeation hole 21 and the liquid guide hole 31 are both arranged at the end close to the air inlet 11, which can reduce or even avoid the residual of the aerosol substrate in the liquid storage area 41 and the buffer area 42.

[0058] In some optional embodiments, in order to ensure the smoothness and uniformity of the aerosol substrate conduction, the number of liquid permeation holes 21 can be at least two, and the at least two liquid permeation holes 21 are arranged along the circumference of the first isolation pipe 20; and / or, the number of liquid guide holes 31 can also be at least two, and the at least two liquid guide holes 31 are arranged along the circumference of the second isolation pipe 30. The first isolation pipe 20 and the second isolation pipe 30 are both tubular structures, and in order to enable the first isolation pipe 20 and the second isolation pipe 30 to uniformly transmit the aerosol substrate, the corresponding liquid permeation hole 21 can be provided with a plurality of liquid permeation holes 21 arranged along the circumference of the first isolation pipe 20, so that each liquid permeation hole 21 can conduct the aerosol substrate from different directions; the structure of the liquid guide hole 31 is similar, and each liquid guide hole 31 can also conduct the aerosol substrate from different directions.

[0059] In the embodiments of the present application, in order to keep the aerosol in the liquid storage area 41 flowing out while slowing down the entry of the aerosol substrate into the atomization area 43, the diameter of the liquid guide hole 31 can be set to be relatively small to slow down the speed of the aerosol substrate permeating into the buffer area 42; while the liquid guide hole 31 is used to guide the aerosol substrate into the atomization area 43, in order to avoid affecting the user's smoking experience, the diameter of the liquid guide hole 31 can be relatively large; in other words, the diameter of the liquid guide hole 31 in the embodiments of the present application can be set to be larger than the diameter of the liquid permeation hole 21.

[0060] In some optional embodiments, please refer to Figure 3 The specific structure of the shell assembly 1 can include: a shell body 13; a top cover 14 arranged at one end of the shell body 13, and the air outlet 12 penetrating the top cover 14; an end seat 15 arranged at the other end of the shell body 13 opposite to the top cover 14, and the air inlet 11 penetrating the end seat 15; the shell body 13, the top cover 14 and the end seat 15 form an internal cavity; the first isolation piece 2 and the second isolation piece 3 are located in the internal cavity and fixed between the end seat 15 and the top cover 14.

[0061] The atomization assembly in the embodiment of the present application can be formed by splicing multiple components, and can include a shell body 13 as a main body, a top cover 14 and an end seat 15 respectively arranged at two ends of the shell body 13. The shell body 13 itself is tubular, and the openings at the two ends are respectively provided with the top cover 14 and the end seat 15. The top cover 14 and the bottom seat are respectively provided with an air outlet 12 and an air inlet 11. The air outlet 12 is used for discharging aerosol, and the air inlet 11 is used for inhaling air. The first isolation piece 2 and the second isolation piece 3 are both arranged in the internal cavity, and the first isolation piece 2 and the second isolation piece 3 are fixed by being connected with the end seat 15 and / or the top cover 14. In addition, the first isolation piece 2 and the second isolation piece 3 in the embodiment of the present application can also be integrally formed with the top cover 14 and / or the end seat 15.

[0062] In some optional embodiments, the internal cavity is divided into a liquid storage area 41, a buffer area 42 and an atomization area 43 by the first isolation piece 2 and the second isolation piece 3. The respective areas are arranged at a relative interval. The aerosol substrate in the liquid storage area 41 enters the buffer area 42 through the liquid permeation hole 21. It is easy to form a negative pressure in the liquid storage area 41, which may affect the aerosol substrate to continue to discharge through the liquid permeation hole 21. In order to avoid the above problem.

[0063] Please refer to Figure 7 and Figure 8 The end seat 15 can be provided with an air exchange channel 16. The air exchange channel 16 is used for communicating the liquid storage area 41 with the outside of the shell assembly 1. By arranging the air exchange channel 16 on the end seat 15, which communicates the liquid storage area 41 with the outside of the shell assembly 1, the generation of negative pressure can be effectively avoided, so that the aerosol substrate can smoothly permeate into the buffer area 42.

[0064] In some optional embodiments, in order to prevent the aerosol substrate from leaking from the air exchange channel 16, the end seat 15 can specifically include a seat body 151 and a sealing sleeve 152. The sealing sleeve 152 is sleeved on the outer wall of the seat body 151 and abuts against the shell body 13. The air exchange channel 16 includes an air exchange groove arranged on the outer wall of the seat body 151 along a predetermined non-linear path, and respectively communicates with the liquid storage area 41 and the air inlet 11.

[0065] The combination of the seat body 151 and the sealing sleeve 152 allows the seat body 151 and the shell body 13 to form a sealed connection. The air exchange channel 16 is formed as an air exchange groove on the outer wall of the seat body 151, and the air exchange groove itself is arranged along a non-linear path, which can effectively prevent the aerosol substrate from leaking from the air exchange groove. In order to communicate the air exchange channel 16 with the outside of the shell assembly 1, the air exchange channel 16 can be directly communicated with the air inlet 11. The sealing sleeve 152 can be made of a flexible material such as silica gel.

[0066] In addition, the air exchange channel 16 can also be formed by providing a through hole in the outer wall of the seat body 151, which can be communicated with the liquid storage area 41 and the air inlet 11.

[0067] In some optional embodiments, although most of the aerosol substrate in the liquid storage area 41 will enter the buffer area 42 through the liquid permeation hole 21, it is not excluded that part of the aerosol substrate may enter the air exchange channel 16. In order to collect the aerosol substrate leaked through the air exchange channel 16, the seat body 151 and the shell body 13 can further form a receiving area 17 which is communicated with the air exchange channel 16. If the aerosol substrate enters the air exchange channel 16, it will flow into the receiving area 17 and temporarily stay in the receiving area 17, so as to avoid the aerosol substrate from leaking to the outside of the atomization device.

[0068] Specifically, the forming mode of the receiving area 17 in the embodiment of the application can be that the outer wall of the seat body 151 has at least two flanges 153 distributed along the axial direction of the seat body 151, the flanges 153 extend along the circumferential direction of the seat body 151, and the gap between adjacent flanges 153 forms the receiving area 17; the flange 153 is further provided with a notch 154 which communicates the receiving area 17 with the air exchange channel 16. The receiving area 17 is formed by the gap between adjacent flanges 153, so that the aerosol substrate can stay in the receiving area 17 under the action of liquid surface tension, preventing the aerosol substrate from leaking outside.

[0069] According to the atomization device provided in the embodiment of the application, since the first partition 2 and the second partition 3 divide the internal cavity into several parts, the aerosol substrate can only slowly permeate into the buffer area 42 through the liquid permeation hole 21, and the permeated aerosol substrate is stored by the buffer 5, thereby slowing down the speed of the aerosol substrate flowing into the liquid storage area 41, avoiding the leakage of the aerosol substrate, and also without the need for manual activation by the user, effectively improving the user experience.

[0070] The above application of specific examples to the application is only used to help understand the application and does not limit the application. For those skilled in the art to which the application belongs, according to the idea of the application, a number of simple deductions, deformations or substitutions can be made.
