[0033] Please refer to Figure 1 In an embodiment, an atomization device is provided, the atomization device comprises an electric control assembly 100 and an atomizer 200. The electric control assembly 100 is used to supply power to the atomizer 200 and control heating of the atomizer 200. The housing of the atomization device can be an integrated structure, the housings of the electric control assembly 100 and the atomizer 200 can be an integrated structure, the housing integration includes using the same housing or mounting and fixing the housings as an integrated structure. The atomization device has an integrated housing, which can improve the structural stability of the atomization device. For example, the atomization device is used as a disposable product, and the housing of the atomization device can be provided as an integrated structure.

[0034] The atomization device can also be a split structure, and the electric control assembly 100 and the atomizer 200 are fixed together in a detachable manner such as clamping and magnetic attraction. When the atomization device is a reusable product, the electric control assembly 100 can be used as a reusable component to reduce the use cost of the user. In addition, the electric control assembly 100 and the atomizer 200 are arranged in a split structure, and one electric control assembly 100 can be connected to multiple different atomization chambers 200, so that the user can choose different atomization chambers 200 according to preference, for example, different atomization chambers 200 have different flavors of atomization substrates, or have different liquid and / or air inlet amounts to form different smoking tastes.

[0035] Please refer to Figures 2 to 4 In some embodiments, the atomizer 200 includes an atomization shell assembly 210 and an atomization core 220. The atomization shell assembly 210 is used to store a liquid atomization substrate. The atomization core 220 is located in the atomization shell assembly 210, and the atomization core 220 is used to heat the liquid atomization substrate. The atomization core 220 has an atomization channel 220a therein.

[0036] The atomization shell assembly 210 includes a first atomization shell 21 and a second atomization shell 22. The atomization core 220 is installed in the first atomization shell 21, and other structural components can also be assembled in the first atomization shell 21. The first atomization shell 21 and the atomization core 220 form a first assembly. The second atomization shell 22 can be assembled with a mouthpiece and other structures, and the second atomization shell 22 forms a second assembly. The first assembly and the second assembly can be irreversibly and unidirectionally installed, for example, the first atomization shell 21 and the second atomization shell 22 are respectively provided with a one-way buckle and a one-way slot. After the first atomization shell 21 and the second atomization shell 22 are clamped, they cannot be disassembled. The atomization shell assembly 210 that cannot be disassembled can be a disposable product. The first assembly and the second assembly can also be reversibly and detachably installed, for example, the first atomization shell 21 and the second atomization shell 22 are respectively provided with detachable buckles and slots. The detachable arrangement makes part of the atomization shell assembly 210 a reusable product, and the first atomization shell 21 with the atomization core 220 can be reused, and the second atomization shell 22 can be replaced to replenish liquid and improve service life.

[0037] The first atomization shell 21 and the second atomization shell 22 can store liquid atomization substrate, wherein the first atomization shell 21 can pre-store a small amount of liquid atomization substrate, for example, 1-2 ml of liquid atomization substrate, and the second atomization shell 22 can store a relatively large amount of liquid atomization substrate, for example, 10-20 ml of liquid atomization substrate. In this way, when the user directly uses the atomizer, the liquid guide in the atomization core 220 has already adsorbed the liquid atomization substrate, and dry burning caused by the fact that the liquid atomization substrate in the second atomization shell 22 has not been introduced into the atomization core 220 can be avoided. In particular, when the first atomization shell 21 and the second atomization shell 22 are separate components and are combined only when used, dry burning caused by the fact that the liquid atomization substrate in the second atomization shell 22 has not been introduced into the atomization core 220 can be avoided.

[0038] The first atomization shell 21 is connected with the second atomization shell 22 through the liquid inlet pipe 212 and the exhaust pipe 213, the second atomization shell 22 can introduce liquid atomization substrate into the first atomization shell 21 through the liquid inlet pipe 212, and the first atomization shell 21 can introduce air into the second atomization shell 22 through the exhaust pipe 213, so that a gas-liquid circuit is formed in the first atomization shell 21 and the second atomization shell 22, and the liquid path and the air flow are distributed through different pipelines to avoid cross interference between the liquid path and the air flow, thereby reducing the occurrence of air lock and making the flow of liquid atomization substrate more smooth.

[0039] The liquid inlet pipe 212 and the exhaust pipe 213 can be integrated with the first atomization shell 21, or the liquid inlet pipe 212 and the exhaust pipe 213 are fixedly installed on the first atomization shell 21. When the first atomization shell 21 and the second atomization shell 22 are assembled, the liquid inlet pipe 212 and the exhaust pipe 213 are inserted into the second atomization shell 22 to realize the liquid path and air flow communication between the first atomization shell 21 and the second atomization shell 22. In this way, the installation is facilitated, and when the second atomization shell 22 is provided as a separate component, the second atomization shell 22 serves as a replaceable component, and liquid replenishment can be realized by replacing the second atomization shell 22.

[0040] Please refer to Figure 4 and Figure 5 In some embodiments, the liquid inlet pipe 212 and the exhaust pipe 213 can also be integrated with the second atomization shell 22, or the liquid inlet pipe 212 and the exhaust pipe 213 are installed in the second atomization shell 22; and part of the liquid inlet pipe 212 and the exhaust pipe 213 are exposed from the second atomization shell 22. When the first atomization shell 21 and the second atomization shell 22 are assembled, the exposed part of the liquid inlet pipe 212 and the exhaust pipe 213 is inserted into the first atomization shell 21, and the liquid path and air flow communication between the first atomization shell 21 and the second atomization shell 22 can also be realized.

[0041] It should be noted that the atomizer of the present application includes the atomizing shell assembly 210 in any of the following embodiments.

[0042] In some embodiments, the atomizing shell assembly 210 can only include the first atomizing shell 21, and the second atomizing shell 22 is a component of the first atomizing shell 21. The user can assemble the first atomizing shell 21 and the second atomizing shell 22 before use. In some embodiments, the atomizing shell assembly 210 can include both the first atomizing shell 21 and the second atomizing shell 22; wherein the first atomizing shell 21 and the second atomizing shell 22 can be assembled structures, which can be directly used by the user; or the first atomizing shell 21 and the second atomizing shell 22 can also be assembled by the user when used.

[0043] Please refer to Figures 4 to 6 In some embodiments, the first atomizing shell 21 includes a main shell 211, a liquid inlet pipe 212, and an exhaust pipe 213.

[0044] The main shell 211 has a first accommodating cavity 21a inside, which is used to accommodate the atomizing core 220. The first accommodating cavity 21a can also be used to accommodate other components, and the first accommodating cavity 21a can also form a liquid guide channel and other structures.

[0045] The liquid inlet pipe 212 and the exhaust pipe 213 are arranged at the same end of the main shell 211, for example, the liquid inlet pipe 212 and the exhaust pipe 213 are arranged at one end of the main shell 211 for atomizing and exhausting. The liquid inlet pipe 212 and the exhaust pipe 213 are respectively communicated with the first accommodating cavity 21a. Wherein, one end of the liquid inlet pipe 212 has a liquid inlet 2121, and the other end has a liquid outlet 2122. The liquid outlet 2122 of the liquid inlet pipe 212 is located on the inner wall of the first accommodating cavity 21a and communicated with the first accommodating cavity 21a. The liquid inlet 2121 of the liquid inlet pipe 212 is located at the end of the liquid inlet pipe 212 away from the main shell 211. One end of the exhaust pipe 213 has an exhaust inlet 2131, and the other end has an exhaust outlet 2132. The exhaust inlet 2131 of the exhaust pipe 213 is located on the inner wall of the first accommodating cavity 21a and communicated with the first accommodating cavity 21a. The exhaust outlet 2132 of the exhaust pipe 213 is located at the end of the exhaust pipe 213 away from the main shell 211, and the exhaust outlet 2132 of the exhaust pipe 213 is farther away from the main shell 211 than the liquid inlet 2121 of the liquid inlet pipe 212.

[0046] The liquid inlet 2121 is located on the circumferential side wall of the end of the liquid inlet pipe 212 away from the main shell 211, and the end of the liquid inlet pipe 212 away from the main shell 211 is provided with an open groove structure forming the liquid inlet 2121, which can guide the liquid atomized substrate to flow into the liquid inlet pipe 212 along the radial direction of the liquid inlet pipe 212. Of course, the end of the liquid inlet pipe 212 away from the main shell 211 has an axial opening which communicates with the liquid inlet 2121. In this way, when the liquid inlet pipe 212 is inserted into the second accommodating cavity 22a, the axial opening of the end of the liquid inlet pipe 212 away from the main shell 211 is blocked by the sealing terminal 2266 or the like, and the liquid inlet 2121 located at the radial position of the liquid inlet pipe 212 is not blocked, so that the liquid inlet can be realized.

[0047] Since the liquid inlet outlet 2122 of the liquid inlet pipe 212 can be part of the main shell 211, the end of the liquid inlet outlet 2122 of the liquid inlet pipe 212 does not need to be inserted and installed, and the liquid inlet outlet 2122 of the liquid inlet pipe 212 can be an axial opening of the liquid inlet pipe 212.

[0048] The exhaust outlet 2132 is located on the circumferential side wall of the end of the exhaust pipe 213 away from the main shell 211, and the end of the exhaust pipe 213 away from the main shell 211 is provided with an open groove structure forming the exhaust outlet 2132, which can exhaust air into the second accommodating cavity 22a along the radial direction of the exhaust pipe 213. Of course, the end of the exhaust pipe 213 away from the main shell 211 has an axial opening which communicates with the exhaust outlet 2132. In this way, when the exhaust pipe 213 is inserted into the second accommodating cavity 22a, the axial opening of the end of the exhaust pipe 213 away from the main shell 211 is blocked by the sealing terminal 2266 or the like, and the exhaust outlet 2132 located at the radial position of the exhaust pipe 213 is not blocked, so that the exhaust can be realized.

[0049] Since the liquid inlet outlet 2122 of the liquid inlet pipe 212 can be part of the main shell 211, the end of the liquid inlet outlet 2122 of the liquid inlet pipe 212 does not need to be inserted and installed, and the liquid inlet outlet 2122 of the liquid inlet pipe 212 can be an axial opening of the liquid inlet pipe 212.

[0050] Among them, the opening area of the liquid inlet 2121 of the liquid inlet pipe 212 is greater than the opening area of the exhaust outlet 2132 of the exhaust pipe 213, that is, the opening of the liquid inlet 2121 is larger, and in use, the liquid guiding pressure formed at the liquid inlet 2121 is greater than the liquid guiding pressure formed at the exhaust outlet 2132, so that the liquid atomized substrate will enter the liquid inlet 2121, and correspondingly, the air will enter the second accommodating cavity 22a from the exhaust outlet 2132 with smaller liquid pressure, forming a gas-liquid circulation in the second accommodating cavity 22, discharging the liquid atomized substrate while introducing air.

[0051] In this embodiment, the liquid inlet pipe 212 and the exhaust pipe 213 are arranged at the same end of the main shell 211 of the first atomization shell 21, and after the first atomization shell 21 and the second atomization shell 22 are assembled, the liquid inlet pipe 212 and the exhaust pipe 213 can be inserted into the inside of the second atomization shell 22. In the use state, the opening area of the liquid inlet 2121 of the liquid inlet pipe 212 is larger than the opening area of the exhaust outlet 2132 of the exhaust pipe 213. In this way, during the operation of the atomization device, the liquid inlet 2121 with a larger opening area will form a larger liquid discharge pressure, which will guide the liquid atomization medium in the second atomization shell 22 to flow into the first atomization shell 21 through the liquid inlet 2121 of the liquid inlet pipe 212, and at the same time, the air in the first atomization shell 21 can enter the second atomization shell 22 through the exhaust outlet 2132 with a smaller opening area, forming a gas-liquid circulation loop; in the gas-liquid circulation loop, the liquid path and the gas path flow through different pipelines respectively, which separates the liquid path and the gas path, so that the flow of the liquid and the flow of the gas do not interfere with each other, thereby reducing the occurrence of air lock phenomenon and making the flow of the liquid atomization medium more smooth.

[0052] Specifically, during the operation of the atomization device, the liquid atomization medium in the second accommodating cavity 22a enters the first accommodating cavity 21a through the liquid inlet pipe 212, and then enters the atomization core 220; at the same time, the outside space enters the first accommodating cavity 21a through the atomization core 220, and then is introduced into the second accommodating cavity 22a through the exhaust pipe 213, forming a gas-liquid circulation.

[0053] In some embodiments, the circumferential side wall of the liquid inlet pipe 212 away from the main shell 211 can be provided with a plurality of liquid inlets 2121, for example, the circumferential side wall of the liquid inlet pipe 212 away from the main shell 211 is provided with two liquid inlets 2121 which are symmetrical along the central axis of the liquid inlet pipe 212. By providing a plurality of liquid inlets 2121, the opening area of the liquid inlet 2121 can be expanded, and the liquid inlet efficiency can be improved; and by arranging the liquid inlets 2121 at different circumferential positions of the liquid inlet pipe 212, the discharge of the liquid atomization medium at different positions in the second atomization cavity 22a can be facilitated.

[0054] Please refer to Figure 4 In some embodiments, the circumferential side wall of the exhaust pipe 213 away from the main shell 211 can be provided with a plurality of exhaust outlets 2132, for example, the circumferential side wall of the exhaust pipe 213 away from the main shell 211 is provided with two exhaust outlets 2132 which are symmetrical along the central axis of the liquid inlet pipe 212. Among them, it is only necessary to ensure that the total opening area of the plurality of exhaust outlets 2132 is smaller than the opening area of one or more liquid inlets 2121. By providing a plurality of exhaust outlets 2132, it can be avoided that a certain exhaust outlet 2132 is blocked during installation, or it can be avoided that a certain exhaust outlet 2132 is close to the side wall and is not conducive to exhaust.

[0055] In some embodiments, the liquid inlet pipe 212 and the exhaust pipe 213 are inserted into the second accommodating cavity 22a from one end of the main shell 211, and the liquid inlet 2121 of the liquid inlet pipe 212 and the exhaust outlet 2132 of the exhaust pipe 213 are located in the second accommodating cavity 22a to realize the distribution of the liquid inlet 2121 and the exhaust outlet 2132 in communication with the second accommodating cavity 22a.

[0056] In some embodiments, only the end portion of the liquid inlet 2121 of the liquid inlet pipe 212 is inserted into the second accommodating cavity 22a, so that the liquid inlet 2121 is as close as possible to the bottom of the second accommodating cavity 22a, which is conducive to guiding all the liquidized atomization matrix in the second accommodating cavity 22a to be heated and atomized, and fully utilizing the liquidized atomization matrix in the second accommodating cavity 22a.

[0057] Please refer to Figure 4 In some embodiments, the liquid inlet pipe 212 and the exhaust pipe 213 are substantially the same in whole, for example, the axial length of the liquid inlet pipe 212 is equal to the axial length of the exhaust pipe 213, and / or the outer diameter of the liquid inlet pipe 212 is equal to the outer diameter of the exhaust pipe 213. In this way, the liquid inlet pipe 212 and the exhaust pipe 213 can be arranged as symmetrical or approximately symmetrical structures, which can reduce the cost of mold opening and manufacturing; and the two insertion holes of the second atomization shell 22 can also be arranged as symmetrical and identical structures, so that the user can align the second atomization shell 22 in any direction to insert the liquid inlet pipe 212 and the exhaust pipe 213 of the first atomization shell 21, which improves the convenience of assembly and avoids the problem of blocked gas-liquid circulation caused by incorrect insertion.

[0058] In some embodiments, the inner diameter of the liquid inlet pipe 212 can be 1mm-2mm; the inner diameter of the exhaust pipe 213 can be 1mm-2mm. For example, the inner diameter of the liquid inlet pipe 212 and the inner diameter of the exhaust pipe 213 are both 1.5mm.

[0059] In some embodiments, the liquid inlet 2121 of the liquid inlet pipe 212 can be an axial opening at one end of the liquid inlet pipe 121, and the exhaust outlet 2132 of the exhaust pipe 213 can be an axial opening of the exhaust pipe 213. The inner diameter of the liquid inlet pipe 212 is greater than the inner diameter of the exhaust pipe 213, and the opening area of the liquid inlet 2121 of the liquid inlet pipe 212 can also be greater than the opening area of the exhaust outlet 2132 of the exhaust pipe 213, so as to form a smooth gas-liquid circulation. This structure is suitable for the liquid inlet pipe 212 and the exhaust pipe 213 being inserted into the rear end of the second atomization shell 22 without being blocked, for example, the liquid inlet pipe 212 and the exhaust pipe 213 being inserted into the second atomization shell 22 with a sealing film.

[0060] Please refer to Figure 5In some embodiments, the main housing 211 can include a first upper shell 2111 and a first bottom cover 2112 connected to the first upper shell 2111 to form a first accommodating cavity 21a inside the first upper shell 2111. The first accommodating cavity 21a has a first inner wall, a second inner wall opposite to the first inner wall, and a side wall connecting the first inner wall and the second inner wall. The first bottom cover 2112 is mounted to an end of the first upper shell 2111 away from the first inner wall. The first inner wall is a top wall in the use state of the first accommodating cavity 21a, and the liquid inlet outlet 2122 of the liquid inlet pipe 212 and the exhaust inlet 2131 of the exhaust pipe 213 are located on the first inner wall.

[0061] The first upper shell 2111 can be provided with a stepped hole limiting structure 2255, and the first bottom cover 2112 and the limiting structure 2255 can install the atomizing core 220 in the main housing 211, i.e., install the atomizing core 220 in the first accommodating cavity 21a.

[0062] Please refer to Figure 5 and Figure 6 In some embodiments, a partition 214 can be provided in the first accommodating cavity 21a, and the partition 214 can be a partition structure. The partition 214 is connected to the first inner wall of the first accommodating cavity 21a. The partition 214 separates the liquid inlet outlet 2122 of the liquid inlet pipe 212 and the exhaust inlet 2131 of the exhaust pipe 213 to separate the liquid path and the gas path in the first accommodating cavity 21a, avoiding the space from entering the liquid inlet pipe 212 to interfere with the injection of the liquid atomization substrate.

[0063] During the use of the atomizing device, bubbles may be generated in the first accommodating cavity 21a, and these bubbles float above the liquid atomization substrate. The partition 214 separates the liquid inlet outlet 2122 of the liquid inlet pipe 212 and the exhaust inlet 2131 of the exhaust pipe 213 to block the bubbles, so that the bubbles are near the inlet of the exhaust pipe 213, and the air in the first accommodating cavity 21a is more easily exhausted from the exhaust pipe 213, and is not easily introduced into the liquid inlet pipe 212 to affect the injection of the liquid atomization substrate.

[0064] Please refer to Figure 5 and Figure 6 In some embodiments, the partition 214 can completely separate the liquid inlet outlet 2122 of the liquid inlet pipe 212 and the exhaust inlet 2131 of the exhaust pipe 213 to form two chambers on both sides of the partition 214. That is, the side edges of the partition 214 are connected to the side walls of the first accommodating cavity 21a. After the partition 214 is connected to the side walls of the first accommodating cavity 21a, the bubbles near the inlet of the exhaust pipe 213 are limited in the chamber on the side of the partition 214 close to the inlet of the exhaust pipe 213, and are difficult to bypass the partition 214, which can greatly reduce the possibility of the bubbles entering the liquid inlet pipe 212.

[0065] The partition 214 divides the first accommodating cavity 21a into a first chamber 21b and a second chamber 21c. The liquid inlet outlet 2122 of the liquid inlet pipe 212 communicates with the first chamber 21b, the first chamber 21b forms a liquid guide channel, and the first chamber 21b can form a liquid storage buffer cavity to accommodate the introduced liquid aerosol substrate. The second chamber 21c is used to accommodate the installed atomizing core 220. The partition 214 is provided with a communication portion at the end away from the first inner wall of the first accommodating cavity 21a. For example, a gap can be formed between the end of the partition 214 away from the first inner wall and the second inner wall of the first accommodating cavity 21a, the gap communicates the first chamber 21b and the second chamber 21c, and / or a gap can be formed between the end of the partition 214 away from the first inner wall and the first bottom cover 2112, the gap communicates the first chamber 21b and the second chamber 21c. The first chamber 21b and the second chamber 21c are communicated, so that the atomizing substrate introduced from the liquid inlet pipe 212 can enter the atomizing core 220 in the second chamber 21c.

[0066] The gap communicating the first chamber 21b and the second chamber 21c is on the side of the partition 214 away from the first inner wall, and the gap is far away from the first inner wall, i.e. the gap is located at the lower end of the first chamber 21b and the second chamber 21c in use. The atomizing core 220 is arranged in the second chamber 21c. During the suction process of the user, a low pressure is formed at the atomizing core 220, and the liquid aerosol substrate enters the first chamber 21b through the liquid inlet pipe 212 under the action of air pressure, and flows to the second chamber 21c through the gap. The bubbles formed in the second chamber 21c are not easy to reach the first chamber 21b through the gap, and are limited in the second chamber 21c and discharged through the exhaust pipe 213.

[0067] For example, the edge of the partition 214 away from the first inner wall has a notch 214a, and the first bottom cover 2112 abuts against the edge of the partition 214 away from the first inner wall, and the gap is formed at the notch 214a.

[0068] The partition 214 can have one or more notches 214a, for example, a plurality of notches 214a are arranged at different positions, which can increase the gap space between the first chamber 21b and the second chamber 21c, so that the liquid aerosol substrate can flow into the second chamber 21c from multiple directions.

[0069] In some embodiments, the partition 214 can be cylindrical, and the second chamber 21c defined by the cylindrical partition 214 is surrounded by the first chamber 21b, so that the liquid aerosol substrate in the first chamber 21b can flow into the second chamber 21c from multiple directions, which is beneficial to the atomizing core 220 in the second chamber 21c.

[0070] Please refer to Figure 5The first bottom cover 2112 is provided with a first sealing member 2113 on the side close to the first accommodating cavity 21a. The first sealing member 2113 is in sealing cooperation with the first upper shell 2111, and the first sealing member 2113 abuts against the edge of the partition 214 away from the first inner wall. The first sealing member 2113 is an elastic structure, for example, the first sealing member 2113 is a silica gel member.

[0071] The first sealing member 2113 is in sealing cooperation with the first upper shell 2111, and the first sealing member 2113 abuts against the edge of the partition 214 away from the first inner wall. The first sealing member 2113 is an elastic structure, for example, the first sealing member 2113 is a silica gel member.

[0072] The first sealing member 2113 is in sealing cooperation with the first upper shell 2111, and the first sealing member 2113 abuts against the edge of the partition 214 away from the first inner wall. The first sealing member 2113 is an elastic structure, for example, the first sealing member 2113 is a silica gel member.

[0073] In some embodiments, the first sealing member 2113 can be integrally formed with the first bottom cover 2112. For example, the first sealing member 2113 and the first bottom cover 2112 can be formed by insert molding process. After the first bottom cover 2112 is made, the first bottom cover 2112 is placed as an insert in a mold for injection molding, and the first sealing member 2113 is directly injection molded on the first bottom cover 2112, so that the first sealing member 2113 and the first bottom cover 2112 are more tightly connected and are not easy to loosen.

[0074] The first bottom cover 2112 can also be used to install an electrode. For example, the electrode can be inserted on the outside of the first bottom cover 2112, i.e., the side away from the first accommodating cavity 21a.

[0075] The middle part of the first bottom cover 2112 can have an air inlet hole for communicating with the atomization channel 220a of the atomization core 220. During the user's suction process, air can enter the atomization channel 220a through the air inlet hole and mix with the formed aerosol.

[0076] Please refer to Figure 7 In some embodiments, the atomization shell assembly 210 includes not only the first atomization shell 21 but also a liquid storage member 216 located in the second chamber 21c of the first atomization shell 21.

[0077] The liquid storage member 216 is a porous structure and can be formed of a fiber fabric, for example, the liquid storage member 216 can be liquid storage cotton. In this way, the liquid storage member 216 has liquid absorption properties and can form a capillary adsorption effect to absorb the atomization base introduced by the liquid inlet pipe 212 into the atomization core 220.

[0078] The upper end of the liquid storage member 216 is arranged close to or abutting against the air outlet 2131. In this way, the liquid storage member 216 can form a liquid sealing effect on the air outlet 2131, so that the liquid aerosol substrate in the second accommodating cavity 22a is difficult to enter the second chamber 21c through the air outlet 2131, and on the contrary, the space in the first accommodating cavity 21a can more easily enter the air pipe 213, improving the smoothness of the air path.

[0079] In some embodiments, the liquid storage member 216 has a ring structure, and the atomization core 220 can be inserted into the liquid storage member 216. The liquid storage member 216 is used to adsorb the liquid aerosol substrate, so that the liquid aerosol substrate can infiltrate the atomization core 220. The porous structure of the liquid storage member 216 can generate capillary action, and the liquid aerosol substrate in the second chamber 21c enters the liquid storage member 216 under the capillary action. Even if the liquid aerosol substrate in the second chamber 21c does not completely immerse the liquid storage member 216, or even if the liquid level of the liquid aerosol substrate in the second chamber 21c is lower than the heating element 223 in the atomization core 220, the liquid storage member 216 can still absorb the liquid aerosol substrate to a higher position under the capillary action, so that the atomization core 220 can be infiltrated by the liquid aerosol substrate. As the atomization core 220 continuously consumes the liquid aerosol substrate in the liquid storage member 216 during operation, the liquid aerosol substrate in the second chamber 21c can also continuously supplement the liquid storage member 216 under the capillary action.

[0080] By arranging the air guide groove 216a on the side wall of the liquid storage member 216, the obstruction of the liquid storage member 216 to the inlet of the air pipe 213 can be reduced, so that the air in the second chamber 21c can more smoothly pass through the air pipe 213 and be discharged.

[0081] In some embodiments, the capillary action is affected by the equivalent pore size of the porous structure. As an example, the equivalent pore size of the liquid storage member 216 can be 10-90 μm. That is, the equivalent pore size of the liquid storage member 216 is several tens of microns, for example, 20 μm, 40 μm, 60 μm, etc. A smaller equivalent pore size can generate a larger capillary force, so that the liquid storage member 216 has a stronger absorption effect on the liquid aerosol substrate, can fully absorb the liquid aerosol substrate, and can always store sufficient liquid aerosol substrate inside the liquid storage member 216 to continuously and stably supply the liquid aerosol substrate to the atomization core 220. Even if the atomizer 200 is in an unused state, the liquid aerosol substrate in the liquid storage member 216 will not flow out, but will always remain inside the liquid storage member 216, so that the liquid storage member 216 remains wet.

[0082] In some embodiments, please refer to Figure 6 The liquid storage member 216 can be attached to the first inner wall and the second inner wall of the first accommodating cavity 21a, and the side wall of the second chamber 21c, so that the liquid storage member 216 is constrained in the second chamber 21c, avoiding the liquid storage member 216 from shaking.

[0083] At least one side wall of the liquid storage member 216 can be flat, and the flat side wall can be attached to the side wall of the second chamber 21c, which can further improve the stability of the liquid storage member 216 and prevent the liquid storage member 216 from being deflected.

[0084] In some embodiments, the main housing 211 of the first atomization housing 21 can have a transparent region. The transparent region is located on at least one side wall of the first chamber 21b.

[0085] The transparent region allows the user to directly observe the amount of liquid atomization substrate remaining in the first accommodating cavity 21a, which facilitates the user to supplement the liquid atomization substrate into the atomizer 200.

[0086] For example, the side wall of the first chamber 21b can have a strip-shaped transparent region, and the length direction of the transparent region can be the same as the length direction of the liquid inlet tube 212. For another example, the main housing 211 can be transparent, i.e., the side wall of the first accommodating cavity 21a is a transparent region.

[0087] Please refer to Figure 5 and Figure 6 In some embodiments, the first atomization housing 21 further includes an aerosol discharge tube 215 connected to one end of the main housing 211. The aerosol discharge tube 215 is located between the liquid inlet tube 212 and the air outlet tube 213, for example, the liquid inlet tube 212 and the air outlet tube 213 are symmetrically arranged about the aerosol discharge tube 215, and the aerosol discharge tube 215 is in communication with the first accommodating cavity 21a.

[0088] The aerosol discharge tube 215 is used to discharge the aerosol formed by the working of the atomization core 220 under the suction of the user. When the first atomization housing 21 is assembled with the second atomization housing 22, the aerosol discharge tube 215 is inserted into the second atomization housing 22. By symmetrically arranging the liquid inlet tube 212 and the air outlet tube 213 about the aerosol discharge tube 215, the first atomization housing 21 is easier to assemble with the second atomization housing 22.

[0089] In some embodiments, the length of the aerosol discharge tube 215 can be greater than the length of the liquid inlet tube 212 and greater than the length of the air outlet tube 213. In this way, the aerosol discharge tube 215 can separate the liquid inlet port 2121 of the liquid inlet tube 212 and the air outlet port 2132 of the air outlet tube 213, which can prevent the air discharged from the air outlet port 2132 from floating to the liquid inlet port 2121 and affecting the liquid inlet.

[0090] In some embodiments, the inner diameter of the aerosol discharge pipe 215 is greater than the inner diameter of the liquid inlet pipe 212 and greater than the inner diameter of the air outlet pipe 213. The inner diameter of the aerosol discharge pipe 215 is set to be larger to facilitate the discharge of the generated aerosol during the operation of the atomizer 200.

[0091] Please refer to Figure 3 、 Figure 4 and Figure 7 In some embodiments, the atomizer housing assembly includes a first atomizer housing 21 and a second atomizer housing 22. The second atomizer housing 22 has a second accommodating cavity 22a formed therein for storing liquid atomization substrate. The second atomizer housing 22 can pre-store liquid atomization substrate in the second accommodating cavity 22a. In this way, the second atomizer housing 22 forms a liquid supplementing combination. After the first atomizer housing 21 and the second atomizer housing 22 are connected, the pre-stored liquid atomization substrate in the second atomizer housing 22 can be introduced into the atomization core 220 in the first atomizer housing 21.

[0092] One end of the second atomizer housing 22 can be provided with a mouthpiece 2244, and the other end of the second atomizer housing 22 has a first insertion hole 22b and a second insertion hole 22c in communication with the second accommodating cavity 22a. The second atomizer housing 22 also has an atomization outlet passage 22d extending from one end to the other end, the atomization outlet passage 22d being located between the first insertion hole 22b and the second insertion hole 22c, and the mouthpiece 2244 being in communication with the atomization outlet passage 22d. The liquid inlet pipe 212 is in communication with the first insertion hole 22b and the second accommodating cavity 22a, and the air outlet pipe 213 is inserted into the second accommodating cavity 22a through the second insertion hole 22c. The aerosol discharge pipe 215 is inserted into the atomization outlet passage 22d.

[0093] Since the opening area of the liquid inlet inlet 2121 of the liquid inlet pipe 212 is greater than the opening area of the air outlet outlet 2132 of the air outlet pipe 213, during the operation of the atomization device, the liquid inlet inlet 2121 with a larger opening area will form a greater liquid discharge pressure, which will guide the liquid atomization substrate in the second accommodating cavity 22a to flow into the first atomizer housing 21 through the liquid inlet inlet 2121 of the liquid inlet pipe 212, while the air in the first atomizer housing 21 can enter the second accommodating cavity 22a through the air outlet outlet 2132 with a smaller opening area, forming a gas-liquid circulation loop. In the gas-liquid circulation loop, the liquid path and the gas path flow through different pipelines respectively, which separates the liquid path and the gas path, so that the flow of liquid and the flow of gas do not interfere with each other, thereby reducing the occurrence of air lock phenomenon and making the flow of liquid atomization substrate more smooth.

[0094] In some embodiments, the mouthpiece 2244 can be integrally formed with the second atomizer housing 22. Alternatively, the mouthpiece 2244 can be detachably connected to the second atomizer housing 22 to facilitate replacement of the mouthpiece 2244.

[0095] In some embodiments, the liquid inlet pipe 212 and the exhaust pipe 213 are symmetrically distributed, and the first insertion hole 22b and the second insertion hole 22c have the same hole diameter. When assembling the first atomization shell 21 and the second atomization shell 22, the liquid inlet pipe 212 can be aligned with any one of the two insertion holes, and the exhaust pipe 213 can be aligned with the remaining one of the two insertion holes, that is, the liquid inlet pipe 212 and the exhaust pipe 213 can be inserted into the two insertion holes, and the aerosol exhaust pipe 215 can be inserted into the mist outlet channel 22d. Even if the first atomization shell 21 is flipped by 180° and the positions of the liquid inlet pipe 212 and the exhaust pipe 213 are transposed, the first atomization shell 21 and the second atomization shell 22 can still be smoothly assembled.

[0096] Please refer to Figure 8 and Figure 9 In some embodiments, the first insertion hole 22b and the second insertion hole 22c are respectively provided with a hole sealing structure, for example, the hole sealing structure is a sealing terminal 2266, and the outer diameter of the sealing terminal 2266 is equal to the inner diameter of the first insertion hole 22b and the second insertion hole 22c or the minimum space in the first insertion hole 22b and the second insertion hole 22c. Therefore, when the second atomization shell 22 is not installed with the first atomization shell 21, the sealing terminal 2266 can seal the first insertion hole 22b and the second insertion hole 22c, so as to facilitate the separate storage and transportation of the first atomization shell 21. When the first atomization shell 21 is assembled with the second atomization shell 22, after the liquid inlet pipe 212 and the exhaust pipe 213 are respectively inserted into the first insertion hole 22b and the second insertion hole 22c, the liquid inlet pipe 212 and the exhaust pipe 213 can extrude the sealing terminal 2266 to the second accommodating cavity 22a, so as to realize the communication of the liquid inlet inlet 2121 of the liquid inlet pipe 212 and the exhaust outlet 2132 of the exhaust pipe 213 with the second accommodating cavity 22a.

[0097] In some embodiments, the second atomization shell 22 has a limiting structure, and the inner side of the first insertion hole 22b and the second insertion hole 22c is respectively provided with a limiting structure, which is used for limiting the sealing terminal 2266 extruded into the second accommodating cavity 22a. For example, the limiting structure is a cylindrical or annular structure, and the minimum inner diameter of the limiting structure is slightly smaller than the outer diameter of the sealing terminal 2266. In this way, after the sealing terminal 2266 is extruded into the second accommodating cavity 22a by the liquid inlet pipe 212 and the exhaust pipe 213, the sealing terminal 2266 is limited and fixed by the limiting structure, so as to avoid the floating of the sealing terminal 2266 in the second accommodating cavity 22a, and further avoid the sealing terminal 2266 from blocking the liquid inlet inlet 2121 of the liquid inlet pipe 212 and the exhaust outlet 2132 of the exhaust pipe 213.

[0098] In some embodiments, the first insertion hole 22b and the second insertion hole 22c are respectively provided with other hole sealing structures, for example, the hole sealing structure is a sealing film. When the second atomization shell 22 is not installed with the first atomization shell 21, the hole sealing structure can seal the first insertion hole 22b and the second insertion hole 22c, so as to facilitate the separate storage and transportation of the first atomization shell 21. The end of the liquid inlet pipe 212 and the exhaust pipe 213 away from the main shell 211 can be provided as a sharp or similar sharp structure, so that when the first atomization shell 21 is assembled with the second atomization shell 22, after the liquid inlet pipe 212 and the exhaust pipe 213 are respectively inserted into the first insertion hole 22b and the second insertion hole 22c, the liquid inlet pipe 212 and the exhaust pipe 213 can pierce the sealing film to realize communication with the second containing cavity 22a.

[0099] In some embodiments, the second atomization shell 22 is connected with the first atomization shell 21 in a detachable manner, and after the liquid atomization substrate in the second atomization shell 22 is consumed, the second atomization shell 22 can be replaced.

[0100] In some embodiments, the second atomization shell 22 can include a second upper shell 2211 and a second bottom cover 2222, and the second bottom cover 2222 is connected with the second upper shell 2211 to form the second containing cavity 22a. The first insertion hole 22b and the second insertion hole 22c can be located on the second bottom cover 2222.

[0101] Please refer to Figure 8 , one end of the second atomization shell 22 is provided with a second sealing member 2233, and the second sealing member 2233 is also located in the first insertion hole 22b, the second insertion hole 22c and the mist outlet channel 22d. The second sealing member 2233 is in sealing cooperation with the liquid inlet pipe 212, the exhaust pipe 213 and the aerosol exhaust pipe 215 respectively.

[0102] The second atomization shell 22 also has an inner pipe 22f, which divides the cavity in the second atomization shell 22 into the second containing cavity 22a and the mist outlet channel 22d. Specifically, the inner pipe 22f can be an integrated structure with the second upper shell 2211, the lower end of the inner pipe 22f is connected with the second bottom cover 2222, and part of the second sealing member 2233 extends between the inner pipe 22f and the second bottom cover 2222 to seal the connection between the inner pipe 22f and the second bottom cover 2222, so as to prevent the leakage of the liquid atomization substrate.

[0103] The second sealing member 2233 is a elastic structure, for example, the second sealing member 2233 can be a silica gel member.

[0104] When the first atomization shell 21 and the second atomization shell 22 are assembled together, the second sealing member 2233 located in the first insertion hole 22b, the second insertion hole 22c and the mist outlet channel 22d can form a seal between the liquid inlet pipe 212 and the hole wall of the first insertion hole 22b, between the air exhaust pipe 213 and the hole wall of the second insertion hole 22c, and between the aerosol exhaust pipe 215 and the inner wall of the mist outlet channel 22d, thereby avoiding leakage of the liquid atomization substrate in the second atomization shell 22. The part of the second sealing member 2233 located at the end of the second atomization shell 22 can form a seal between the end surface of the first atomization shell 21 and the end surface of the second atomization shell 22, thereby further avoiding leakage of the liquid atomization substrate to the outside of the atomization shell assembly. Since the second sealing member 2233 is an integral whole, the parts located at the end surface of the second atomization shell 22, in the first insertion hole 22b, the second insertion hole 22c and the mist outlet channel 22d are connected as one, and are not easy to loosen and displace, thereby providing better sealing performance.

[0105] Reference is made to Figure 2 In some embodiments, an atomizer 200 can include an atomization core 220 and any of the foregoing atomization shell assemblies 210. The atomization core 220 is located in the first accommodating cavity 21a.

[0106] When the foregoing atomization shell assembly 210 is applied to the atomizer 200, the opening area of the liquid inlet 2121 of the liquid inlet pipe 212 is larger than the opening area of the air exhaust outlet 2132 of the air exhaust pipe 213. In this way, during the operation of the atomization device, the liquid inlet 2121 with a larger opening area will form a larger liquid discharge pressure, which will guide the liquid atomization substrate in the second atomization shell 22 to flow into the first atomization shell 21 through the liquid inlet 2121 of the liquid inlet pipe 212, while the air in the first atomization shell 21 can enter the second atomization shell 22 through the air exhaust outlet 2132 with a smaller opening area, forming a gas-liquid circulation loop. In the gas-liquid circulation loop, the liquid path and the gas path flow through different pipelines respectively, which separates the liquid path and the gas path, so that the flow of the liquid and the flow of the gas do not interfere with each other, thereby reducing the occurrence of air lock phenomenon and making the flow of the liquid atomization substrate more smooth.

[0107] Reference is made to Figure 5 In some embodiments, the atomization core 220 can include a support 221, a liquid guide 222, a heating element 223 and a pin 224. The support 221 forms an atomization channel 220a, and the liquid guide 222 and the heating element 223 are located in the support 221. The heating element 223 can be connected to the pin 224, and the pin 224 is electrically connected to the electrode mounted on the first bottom cover 2112.

[0108] The bracket 221 provides a space inside the first atomization shell 21 to accommodate the liquid guide 222 and the heating element 223, and provides support.
