[0004] Atomizers are used to hold liquid medications, e-liquids, and other atomizing liquids and atomize them into aerosols. However, atomizers in related technologies are susceptible to leakage due to changes in environment, such as pressure and ambient temperature, during storage and transportation. This can lead to changes in the volume of liquid within the tank and negatively impact the user experience. Summary of the Invention

[0015] The housing assembly has an air inlet, and the atomizing seat includes a ventilation channel. One end of the ventilation channel is connected to the oil tank, and the other end of the ventilation channel extends to the liquid storage surface. The liquid storage surface is connected to the air inlet through the first capillary pore. The ventilation channel has a ventilation outlet extending to the liquid storage surface, and the height of the ventilation outlet is the same as the height of the liquid storage surface.

[0016] In one embodiment, the housing assembly has an air inlet, and the atomizer also has a leakage storage cavity located on the bottom side of the liquid storage surface, wherein the first capillary pore communicates with the air inlet through the leakage storage cavity.

[0017] In one embodiment, the leakage storage cavity includes a first sub-cavity, and the atomizing seat includes a heating top cover and a heating seat. The heating top cover has the liquid storage surface, and the heating seat is located on the bottom side of the heating top cover. The heating top cover and the heating seat together form the first sub-cavity. A portion of the bottom wall of the first sub-cavity penetrates to form a second capillary pore. The first capillary pore, the first sub-cavity, the second capillary pore, and the air inlet are sequentially connected.

[0018] In one embodiment, the leakage storage cavity further includes a second sub-cavity. The housing assembly includes a housing body and an air inlet cover. The housing body has the oil reservoir, and the air inlet cover has the air inlet hole. At least a portion of the air inlet cover and the atomizing seat are located within the housing body, and the air inlet cover is located on the side of the heating seat opposite to the heating top cover. The air inlet cover and the heating seat enclose the second sub-cavity, and the second capillary pore communicates with the air inlet hole through the second sub-cavity.

[0019] In one embodiment, the leakage storage cavity further includes a third sub-cavity. The air inlet cover and the heating base enclose the second sub-cavity and the third sub-cavity.

After the negative pressure is eliminated, it can flow back into the oil tank along both the leakage path and the liquid supply path, thereby reducing the risk of leakage. Furthermore, the liquid storage surface has a first capillary formed through it. Therefore, the atomized liquid squeezed into the liquid storage surface during negative pressure or warm flushing can form a liquid film at the first capillary. Under the action of the surface tension of the liquid film, the atomized liquid on the liquid storage surface can be locked on the liquid storage surface, thereby achieving liquid sealing. This allows the atomized liquid on the liquid storage surface to flow back into the oil tank along the leakage path after the negative pressure is eliminated, thereby reducing the risk of atomized liquid leakage.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] One embodiment of this application provides an atomizer, as shown in Figures 1, 4 and 5. The atomizer includes a housing assembly 10 and an atomizing assembly 20.

[0039] The housing assembly 10 has an oil reservoir 10a.

[0040] Please refer to Figures 2, 3, and 6. The atomizing assembly 20 is disposed within the housing assembly 10. The atomizing assembly 20 includes an atomizing base 21 and an atomizing core 22. The atomizing core 22 is at least partially disposed within the atomizing base 21. The oil reservoir 10a and the atomizing core 22 are in fluid communication via a liquid supply path. The atomizing base 21 has a liquid storage surface 21d. In one specific embodiment, the atomizing core 22 has a liquid storage surface 21d on at least one side along the lateral direction. The liquid storage surface 21d has a first capillary pore 21e formed through the liquid storage surface 21d. The side of the liquid storage surface 21d near the atomizing core 22 extends to the atomizing core 22 and is in fluid communication with the atomizing core 22 via a leakage path.

[0041] Specifically, the oil tank 10a is the structure of the atomizer used to store atomized liquids such as medicine and e-liquid. In fact, the housing assembly 10 also includes an air inlet 10b and an air outlet. During the user's inhalation, external airflow flows into the housing assembly 10 through the air inlet 10b and flows out through the air outlet.

[0042] The atomizing core 22 of the atomizing assembly 20 is used to atomize the atomizing liquid from the oil tank 10a into an aerosol, so that the aerosol can flow with the airflow for the user to inhale. The atomizing core 22 can be partially disposed within the atomizing base 21, or the entire area can be disposed within the atomizing base 21. The specific arrangement can be set according to the actual situation.

[0043] For example, the atomizing seat 21 has an atomizing cavity 21a, the atomizing core 22 is at least partially disposed in the atomizing cavity 21a, and the atomizing cavity 21a is open at least along a portion of the cavity wall on one lateral side to form a liquid storage cavity 21c, the bottom wall of the liquid storage cavity 21c forming a liquid storage surface 21d.

[0044] The atomizing chamber 21a of the atomizing seat 21 is used to install the atomizing core 22 so that the atomizing core 22 can heat and atomize the atomizing liquid from the oil tank 10a.

[0045] In some embodiments, the atomizer base 21 also has a ventilation channel 21b. The two ends of the ventilation channel 21b are respectively connected to the oil tank 10a and the atomizing chamber 21a. As the user inhales, a negative pressure is generated in the oil tank 10a due to the consumption of atomized liquid, which affects the smooth flow of atomized liquid to the atomizing chamber 21a and the atomizing core 22. By setting the ventilation channel 21b, it is convenient to replenish air into the oil tank 10a to balance the pressure difference between the oil tank 10a and the outside atmosphere, so as to facilitate the smooth flow of atomized liquid to the atomizing chamber 21a and the atomizing core 22.

[0046] A liquid supply path is formed between the oil tank 10a and the atomizing core 21. The liquid supply path refers to the liquid flow path through which the atomizing liquid in the oil tank 10a flows into the atomizing core 21. Under the user's suction action, the atomizing liquid in the oil tank 10a can flow along the liquid supply path to the atomizing core 22 for atomization.

[0047] The liquid storage surface 21d is a structure within the atomizer base 21 used to store leaked liquid. In practice, since the atomizer core 22 is directly connected to the outside environment, when the environment of the atomizer changes, such as changes in ambient temperature or pressure, the atomized liquid in the oil tank 10a can easily flow out through the supply path under negative pressure. This leaked atomized liquid can easily leak from the air inlet 10b, air outlet, or even the atomizer core 22 to the outside of the housing assembly 10, causing leakage. This embodiment of the application, by providing the liquid storage surface 21d, can collect and store at least a portion of the atomized liquid flowing out from the supply path, thereby reducing the problem of atomized liquid leakage to the outside of the housing assembly 10. Simultaneously, after the negative pressure is eliminated, at least a portion of the atomized liquid in the liquid storage surface 21d can flow back into the oil tank 10a along the leakage path and the supply path, further reducing atomized liquid waste.

[0048] A portion of the liquid storage surface 21d is penetrated to form a first capillary pore 21e. The first capillary pore 21e has a capillary structure with a small pore size, which allows the atomized liquid to form a liquid film under the action of surface tension at the first capillary pore 21e when it flows into the liquid storage surface 21d. This locks the atomized liquid within the liquid storage surface 21d as much as possible, reducing the possibility of it flowing out from the first capillary pore 21e.

[0049] In some embodiments, the first capillary 21e is connected to the air inlet 10b, thereby allowing external gas to pass through and forming a partial air intake channel to ensure the atomizer's suction effect.

[0050] It should be noted that the specific size of the first capillary pore 21e can be determined according to the actual situation. It only needs to be able to form a liquid film under the action of surface tension so as to achieve a certain effect of locking the atomized liquid.

[0051] For example, the diameter of the first capillary pore 21e is greater than or equal to 0.4 mm and less than or equal to 0.6 mm. Such as 0.4 mm, 0.5 mm, or 0.6 mm. Setting the diameter of the first capillary pore 21e within the above range can achieve a better leak-proof effect.

[0052] The specific number of the first capillary pores 21e can be set according to the actual situation. For example, the liquid storage surface 21d has multiple first capillary pores 21e arranged at intervals.

[0053] The liquid reservoir 21d and the atomizing core 22 are fluidly connected via a leakage path, which refers to the liquid flow path that allows liquid leaking from the atomizing core 22 to flow to the liquid reservoir 21d. When the environment of the atomizer changes, the atomized liquid leaking from the oil tank 10a can flow to the atomizing core 22 and then flow along the leakage path to the liquid reservoir 21d.

[0054] In the atomizer of this embodiment, the atomizing core 22 is at least partially disposed within the atomizing base 21. The oil tank 10a and the atomizing core 22 are fluidly connected via a liquid supply path. The atomizing base 21 has a liquid storage surface 21d. The atomizing core 22 has a liquid storage surface 21d on at least one side along the transverse direction. The side of the liquid storage surface 21d closest to the atomizing core 22 extends to the atomizing core 22, and the liquid storage surface 21d and the atomizing core 22 are fluidly connected via a leakage path. Thus, by providing a liquid storage surface 21d on at least one side of the atomizing core 22 along the transverse direction, the atomized liquid in the oil tank 10a, after flowing out from the liquid supply path due to negative pressure or thermal flushing, can be squeezed into the liquid storage surface 21d through the leakage path. After the negative pressure is eliminated, it can flow back into the oil tank 10a along the leakage path and the liquid supply path, thereby reducing the risk of leakage. Furthermore, the liquid storage surface 21d has a first capillary pore 21e formed through it. Thus, the atomized liquid squeezed into the liquid storage surface 21d during negative pressure or warm flushing can form a liquid film at the first capillary pore 21e. Under the action of the surface tension of the liquid film, the atomized liquid in the liquid storage surface 21d can be locked in the liquid storage surface 21d, thereby achieving liquid sealing. This allows the atomized liquid in the liquid storage surface 21d to flow back into the oil tank 10a along the leakage path after the negative pressure is removed, thereby reducing the risk of atomized liquid leakage.

[0055] In one embodiment, referring to Figures 3 and 6, the atomizing assembly 20 includes a ceramic silica gel 23, which at least partially surrounds the atomizing core 22. At least one side of the ceramic silica gel 23 in the circumferential direction has a liquid storage surface 21d. The ceramic silica gel 23 includes a first sidewall near the liquid storage surface 21d, the top surface of which is lower than or equal to the height of the liquid storage surface 21d. Therefore, when the external negative pressure is eliminated, the leaked liquid collected in the liquid storage surface 21d can easily flow back into the oil tank 10a through the ceramic silica gel 23, further improving the effect of leaked liquid return.

[0056] Specifically, the ceramic silica gel 23 is disposed around the atomizing core 22. Under the suction action, the atomizing liquid in the oil tank 10a can flow along the liquid supply path to be supplied to the atomizing core 22 through the ceramic silica gel 23 so that the atomizing core 22 can atomize.

[0057] A liquid storage surface 21d is provided on one or more sides of the ceramic silica gel 23 along the circumferential direction, which facilitates the leakage of atomized liquid into the liquid storage surface 21d under negative pressure. After the negative pressure is eliminated, it can be better returned to the oil tank 10a through the ceramic silica gel 23.

[0058] In related technologies, atomizers use absorbent cotton to absorb and retain liquid. However, when the negative pressure disappears, the outflowing atomized liquid is difficult to return to the oil tank, resulting in a drop in the liquid level in the oil tank and a reduction in the number of inlets.

[0059] In this embodiment, the first sidewall of the ceramic silicone 23 is the sidewall on the same side as the liquid storage surface 21d. By making the top surface of the first sidewall flush with the liquid storage surface 21d, or making the top surface of the first sidewall lower than the liquid storage surface 21d, the atomized liquid collected at the liquid storage surface 21d can flow smoothly to the ceramic silicone 23, and then can better flow back to the oil tank 10a, thus improving the effect of leakage return.

[0060] In one embodiment, the height of the liquid storage surface 21d is the same as the height of the atomizing surface of the atomizing core 22.

[0061] In fact, the atomizing surface of the atomizing core 22 is located on the top side of the atomizing core 22. Therefore, by making the liquid storage surface 21d flush with the atomizing surface of the atomizing core 22, the atomizing core 22 as a whole can be lower than the liquid storage surface 21d, which can facilitate the backflow of the atomized liquid in the liquid storage surface 21d from the atomizing core 22.

[0062] In one embodiment, referring to Figures 7, 8 and 9, the housing assembly 10 has an air inlet 10b, and the atomizing seat 21 includes a ventilation channel 21b. One end of the ventilation channel 21b is connected to the oil reservoir 10a, and the other end of the ventilation channel 21b extends to the liquid storage surface 21d. The liquid storage surface 21d is connected to the air inlet 10b through a first capillary pore 21e. The ventilation channel 21b has a ventilation outlet 21ba extending to the liquid storage surface 21d, and the height of the ventilation outlet 21ba is the same as the height of the liquid storage surface 21d.

[0063] In practice, when the atomizer is equipped with a ventilation channel 21b, changes in the environment around the atomizer can easily cause the atomized liquid in the oil tank 10a to flow out through the ventilation channel 21b under negative pressure, resulting in leakage. However, the atomizer in this embodiment allows more of the atomized liquid in the reservoir 21d to be squeezed back into the oil tank 10a by the atmosphere through the ventilation channel 21b when the external negative pressure is eliminated, further improving the atomized liquid recirculation effect.

[0064] In one embodiment, referring to Figures 7, 8, and 9, a plurality of liquid guiding strips 211 protrude from a portion of the liquid storage surface 21d at least near the atomizing core 22. These strips 211 are spaced apart to form capillary liquid guiding grooves 21f at the intervals. The end of the capillary liquid guiding groove 21f near the atomizing core 22 extends to the atomizing core 22. This facilitates the collection of atomized liquid within the liquid storage surface 21d into the capillary liquid guiding grooves 21f, and allows for better backflow through the atomizing core 22 when the external negative pressure is eliminated.

[0065] Specifically, multiple spaced liquid guiding strips 211 are formed on the liquid storage surface 21d, and capillary liquid guiding grooves 21f are formed between adjacent liquid guiding strips 211. The capillary liquid guiding grooves 21f are capillary structures that collect atomized liquid, and the atomized liquid leaking from the oil tank 10a into the liquid storage surface 21d can be collected in the capillary liquid guiding grooves 21f under the action of capillary force.

[0066] By extending the capillary liquid guiding groove 21f to the atomizing core 22, when the external negative pressure is eliminated, the atomized liquid in the capillary liquid guiding groove 21f can flow back to the oil tank 10a through the atomizing core 22 along the leakage path and the liquid supply path under the action of atmospheric pressure. The capillary liquid guiding groove 21f has a liquid guiding effect, which can improve the backflow effect of the atomized liquid.

[0067] It should be noted that the specific arrangement of the capillary liquid guiding groove 21f is not limited. For example, one end of the capillary liquid guiding groove 21f near the atomizing core 22 extends to the atomizing core 22, and the other end of the capillary liquid guiding groove 21f extends in a direction away from the atomizing core 22.

[0068] For example, the liquid storage surface 21d includes a first region on the side close to the atomizing core 22 and a second region on the side away from the atomizing core 22. The first region has a plurality of liquid guiding strips 211 and the second region has a plurality of first capillary pores 21e.

[0069] In one embodiment, referring to Figures 6 and 10, the atomizing base 21 has a liquid discharge channel 21g, one end of which is connected to the oil reservoir 10a, and the other end of which extends to the ceramic silica gel 23. The ceramic silica gel 23 has the liquid discharge channel 21g on at least one side along its length and a liquid storage surface 21d on at least one side along its width. This increases the width of the liquid storage surface 21d, facilitating better backflow of the atomized liquid within it.

[0070] Specifically, the oil tank 10a is connected to the atomizing core 22 through the liquid lowering channel 21g.

[0071] The two opposite sides of the ceramic silicone 23 along its length are the two opposite sides of the ceramic silicone 23 along its long side, and the two opposite sides of the ceramic silicone 23 along its width are the two opposite sides of the ceramic silicone 23 along its short side.

[0072] By setting the liquid storage surface 21d on one side or opposite sides of the ceramic silicone 23 along the width direction, the liquid storage surface 21d can be arranged in a wider position, which can facilitate increasing the width of the connection between the liquid storage surface 21d and the atomizing core 22, thereby facilitating the return of the atomizing liquid in the liquid storage surface 21d.

[0073] In one embodiment, referring to Figure 5, the housing assembly 10 has an air inlet 10b, and the atomizer also has a leakage storage chamber 10c, which is located on the bottom side of the liquid storage surface 21d. The first capillary 21e communicates with the air inlet 10b through the leakage storage chamber 10c. This further reduces the risk of leakage.

[0074] In fact, the leakage storage chamber 10c is located on the communication path between the first capillary pore 21e and the air inlet pore 10b. Therefore, under certain specific conditions, such as when a negative pressure or temperature surge occurs in the external environment, accompanied by severe vibration, some of the atomized liquid in the liquid storage surface 21d may break through the surface tension at the first capillary pore 21e under the action of inertial force. It will not easily leak out from the air inlet pore 10b, but will be preferentially collected in the leakage storage chamber 10c, thus further improving the leak-proof performance of the atomizer.

[0075] In one embodiment, referring to Figures 5, 11, and 12, the leakage storage chamber 10c includes a first sub-chamber 10ca, and the atomizing seat 21 includes a heating top cover 213 and a heating seat 214. The heating top cover 213 has a liquid storage surface 21d, and the heating seat 214 is located on the bottom side of the heating top cover 213. The heating top cover 213 and the heating seat 214 enclose and form the first sub-chamber 10ca. A portion of the bottom wall of the first sub-chamber 10ca extends through to form a second capillary pore 10d. The first capillary pore 21e, the first sub-chamber 10ca, the second capillary pore 10d, and the air inlet pore 10b are sequentially connected. This further improves the leak-proof performance of the atomizer.

[0076] Specifically, a first capillary pore 21e is formed on the top side of the first sub-cavity 10ca, thereby enabling communication with the first capillary pore 21e to collect the atomized liquid leaking from the first capillary pore 21e.

[0077] A second capillary pore 10d is formed on the bottom side of the first sub-cavity 10ca. The second capillary pore 10d has a capillary structure with a small pore size. When the atomized liquid flows into the first sub-cavity 10ca, the surface tension at the second capillary pore 10d allows the atomized liquid to form a liquid film, thereby locking the atomized liquid within the first sub-cavity 10ca as much as possible and reducing the possibility of it flowing out from the second capillary pore 10d. At the same time, since the second capillary pore 10d is connected to the air inlet pore 10b, it can also allow external gas to pass through, forming a partial air inlet channel 122a to ensure the suction effect of the atomizer.

[0078] The first capillary pore 21e, the first sub-cavity 10ca, the second capillary pore 10d, and the air inlet pore 10b are connected in sequence. That is to say, an air inlet path is formed between the air inlet pore 10b and the first capillary pore 21e, which passes through the second capillary pore 10d and the first sub-cavity 10ca in sequence.

[0079] In related technologies, during the atomization process, the suction creates negative pressure inside the atomizer. When the suction ends, due to the large diameter of the air outlet, air rushes into the atomization chamber relatively quickly, causing some aerosol to be ejected from the air inlet at the bottom of the atomizer. This aerosol then comes into contact with the SPCC or the inner wall of the battery at the bottom of the atomizer, where it condenses and leaks, affecting its use.

[0080] In the atomizer of this embodiment, the first sub-cavity 10ca is connected to the liquid storage surface 21d through the first capillary 21e and to the air inlet 10b through the second capillary 10d. Therefore, at the end of the atomization, because the air passage through the first capillary 21e and the second capillary 10d is slow and the pressure recovery is relatively delayed, the first sub-cavity 10ca becomes a negative pressure zone relative to the top side of the liquid storage surface 21d and the air inlet 10b. Atmosphere flows into the first sub-cavity 10ca from both the front and rear ends through the first capillary 21e and the second capillary 10d. This allows the residual aerosol to remain in the first sub-cavity 10ca and not escape from the bottom of the atomizer through the air inlet 10b and hang on the outer wall of the atomizer, thus reducing the risk of condensation and leakage.

[0081] In one specific embodiment, the atomizing base 21 further includes a top cover silicone 212. The top cover silicone 212 is located on the side of the heating top cover 213 away from the heating base 214, and the heating top cover 213 and the top cover silicone 212 together form an atomizing chamber 21a, a ventilation channel 21b, and a liquid storage chamber 21c. That is, the atomizing chamber 21a, the ventilation channel 21b, and the liquid storage chamber 21c are all formed by the heating top cover 213 and the top cover silicone 212. The top cover silicone 212 is located on the side of the heating top cover 213 closer to the oil tank 10a, and the heating base 214 is located on the side of the heating top cover 213 away from the oil tank 10a.

[0082] In one embodiment, referring to Figures 5, 11, 12 and 13, the leakage storage cavity 10c further includes a second sub-cavity 10cb. The housing assembly 10 includes a housing body 11 and an air inlet cover 12. The housing body 11 has an oil reservoir 10a, and the air inlet cover 12 has an air inlet 10b. At least a portion of the air inlet cover 12 and the atomizing seat 21 are located within the housing body 11, and the air inlet cover 12 is located on the side of the heating seat 214 away from the heating top cover 213. The air inlet cover 12 and the heating seat 214 enclose the second sub-cavity 10cb, and the second capillary pore 10d communicates with the second sub-cavity 10cb and the air inlet 10b.

[0083] Specifically, the second sub-cavity 10cb is located on the side of the second capillary 10d away from the first sub-cavity 10ca, and the second sub-cavity 10cb is formed by the air inlet cover 12 and the heating base 214.

[0084] Therefore, by setting a second sub-cavity 10cb between the second capillary 10d and the air inlet 10b, under certain specific conditions, such as when negative pressure or temperature surge occurs in the external environment, accompanied by severe vibration, even if some atomized liquid can pass through the first capillary 21e and the first sub-cavity 10ca and leak out from the second capillary 10d, it can be collected and stored in the second sub-cavity 10cb, which can reduce the risk of leakage directly from the air inlet 10b, and thus further improve the leak-proof performance of the atomizer.

[0085] In one embodiment, referring to Figures 5 and 13, the leakage storage chamber 10c further includes a third sub-chamber 10cc. The air inlet cover 12 and the heating base 214 enclose and form the second sub-chamber 10cb and the third sub-chamber 10cc. A portion of the bottom wall of the air inlet cover 12 protrudes towards the side closest to the heating base 214 to form a first partition wall 121 separating the second sub-chamber 10cb and the third sub-chamber 10cc. The bottom wall of the third sub-chamber 10cc has an air inlet 10b, and the first partition wall 121 has a first air passage 121a. The first air passage 121a communicates with both the second sub-chamber 10cb and the third sub-chamber 10cc, and its height is higher than the bottom walls of the third sub-chamber 10cc and the second sub-chamber 10cb. Therefore, the leak-proof performance of the atomizer can be further improved without significantly affecting the air intake effect.

[0086] Specifically, within the enclosed space of the air intake cover 12 and the heating base 214, a second sub-cavity 10cb and a third sub-cavity 10cc can be separated by a first partition wall 121. The second sub-cavity 10cb is connected to the second capillary pore 10d, and the third sub-cavity 10cc is connected to the air intake pore 10b. The second sub-cavity 10cb and the third sub-cavity 10cc are connected by a first air passage pore 121a on the first partition wall 121.

[0087] It should be noted that the opening height of the first vent 121a is located above the bottom wall of the third sub-cavity 10cc and the bottom wall of the second sub-cavity 10cb. Therefore, even if the atomized liquid passes through the first capillary 21e, the first sub-cavity 10ca, and the second capillary 10d sequentially into the second sub-cavity 10cb, the higher opening height of the first vent 121a will allow more atomized liquid to accumulate in the second sub-cavity 10cb, thereby further reducing the risk of leakage.

[0088] The third sub-cavity 10cc and the second sub-cavity 10cb are formed by the separation of the first partition wall 121, and the specific separation method is not limited.

[0089] For example, the first partition wall 121 extends circumferentially around the air inlet 10b to enclose and form a third sub-cavity 10cc. That is, the third sub-cavity 10cc is located inside the first partition wall 121, while the second sub-cavity 10cb is located outside the first partition wall 121.

[0090] For example, the first partition wall 121 encloses and forms the second sub-cavity 10cb. That is, the second sub-cavity 10cb is located inside the first partition wall 121, while the third sub-cavity 10cc is located outside the first partition wall 121.

[0091] For example, the first partition wall 121 and the side wall of the air intake cover 12 together enclose the second sub-cavity 10cb, and together enclose the third sub-cavity 10cc.

[0092] In one embodiment, referring to Figures 5 and 13, the wall of the air inlet 10b protrudes towards the side near the heating base 214 to form a second partition wall 122. The second partition wall 122 encloses an air intake channel 122a communicating with the air inlet 10b. The end of the air intake channel 122a opposite to the air inlet 10b has a second vent 122b communicating with the third sub-cavity 10cc. The height of the second vent 122b is higher than the height of the bottom wall of the third sub-cavity 10cc and the bottom wall of the second sub-cavity 10cb. This further reduces the risk of leakage.

[0093] Specifically, the third sub-cavity 10cc is connected to the air intake channel 122a via the second vent 122b, and further connected to the air intake 10b. By extending the wall of the air intake 10b towards the side closer to the heating base 214, the second vent 122b can be made higher than the bottom wall of the third sub-cavity 10cc and the bottom wall of the second sub-cavity 10cb. Therefore, even if the atomized liquid passes sequentially through the first capillary 21e, the first sub-cavity 10ca, the second capillary 10d, the second sub-cavity 10cb, and the first vent 121a into the third sub-cavity 10cc, the higher opening height of the second vent 122b allows more atomized liquid to accumulate in the second sub-cavity 10cb and the third sub-cavity 10cc, thereby further reducing the risk of leakage.
