In the description of the embodiments of the present application, the meaning of "multiple" is two and more than two, unless otherwise explicitly and specifically limited.

[0038] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The occurrence of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a separate or alternative embodiment to the other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined.

[0039] An embodiment of the present application provides an atomizer, please refer to Figure 1 , Figure 4 and Figure 5 , the atomizer comprises a shell assembly 10 and an atomization assembly 20.

[0040] The shell assembly 10 has an oil tank 10a.

[0041] Please refer to Figure 2 , Figure 3 and Figure 6 , the atomization assembly 20 is arranged in the shell assembly 10, the atomization assembly 20 comprises an atomization seat 21 and an atomization core 22, the atomization core 22 is arranged at least partially in the atomization seat 21, the oil tank 10a and the atomization core 22 are in fluid communication through a liquid supply path, the atomization seat 21 has a liquid storage surface 21d, the atomization core 22 is provided with the liquid storage surface 21d along at least one side in the lateral direction, the liquid storage surface 21d has a first capillary hole 21e formed therethrough, the liquid storage surface 21d extends to the atomization core 22 at a side close to the atomization core 22, and the liquid storage surface 21d and the atomization core 22 are in fluid communication through a liquid leakage path.

[0042] Specifically, the oil tank 10a is a structure for storing atomization liquid such as medicine liquid and tobacco tar for the atomizer. In fact, the shell assembly 10 also comprises an air inlet hole 10b and an air outlet hole. During the user's suction process, external airflow flows into the shell assembly 10 from the air inlet hole 10b and flows out from the air outlet hole.

[0043] The atomization core 22 of the atomization assembly 20 is used to atomize the atomization liquid from the oil tank 10a to form an aerosol, so that the aerosol flows with the airflow to facilitate the user to smoke. The atomization core 22 can be partially arranged in the atomization seat 21, or can be arranged in the entire region of the atomization seat 21. The specific arrangement mode can be set according to the actual situation.

[0044] For example, the atomization seat 21 has an atomization cavity 21a, the atomization core 22 is at least partially arranged in the atomization cavity 21a, and the atomization cavity 21a is open at least along a part of the cavity wall of the lateral side to form a liquid storage cavity 21c, and the bottom wall of the liquid storage cavity 21c forms a liquid storage surface 21d.

[0045] The atomization cavity 21a of the atomization seat 21 is used to mount the atomization core 22, so that the atomization core 22 atomizes the atomization liquid from the oil tank 10a.

[0046] In some embodiments, the atomization seat 21 also has an air exchange channel 21b. The opposite ends of the air exchange channel 21b are in communication with the oil tank 10a and the atomization cavity 21a, respectively. As the user smokes, negative pressure is generated in the oil tank 10a due to the consumption of the atomization liquid, thereby affecting the smooth flow of the atomization liquid to the atomization cavity 21a and the atomization core 22. By providing the air exchange channel 21b, air can be supplied to the oil tank 10a to balance the pressure difference between the oil tank 10a and the outside atmosphere, thereby facilitating the smooth flow of the atomization liquid to the atomization cavity 21a and the atomization core 22.

[0047] A liquid supply path is formed between the oil tank 10a and the atomization core 21, which refers to a liquid flow path for the atomization liquid in the oil tank 10a to flow into the atomization core 21. Under the action of the user smoking, the atomization liquid in the oil tank 10a can flow along the liquid supply path to the atomization core 22 for atomization by the atomization core 22.

[0048] The liquid storage surface 21d is a structure in the atomization seat 21 for storing leaked liquid. In fact, since the atomization core 22 is directly in communication with the outside, when the environment of the atomizer changes, such as changes in the ambient temperature or pressure, the atomization liquid in the oil tank 10a is prone to flowing out under the action of negative pressure, and the atomization liquid flowing out is prone to leaking from the air inlet hole 10b or the air outlet hole, or even the atomization core 22, to the outside of the shell assembly 10, causing the problem of liquid leakage. The present application embodiment can collect and store at least part of the atomization liquid flowing out of the liquid supply path by providing the liquid storage surface 21d, thereby reducing the problem of atomization liquid leaking out of the shell assembly 10. At the same time, after the negative pressure is eliminated, at least part of the atomization liquid in the liquid storage surface 21d can flow back to the oil tank 10a along the liquid leakage path and the liquid supply path in the opposite direction, thereby reducing the waste of atomization liquid.

[0049] A portion of the liquid storage surface 21d is perforated to form a first capillary hole 21e. The first capillary hole 21e is a capillary hole structure with a small hole diameter, such that when atomized liquid flows into the liquid storage surface 21d, the atomized liquid can form a liquid film under the action of surface tension at the first capillary hole 21e, thereby locking the atomized liquid in the liquid storage surface 21d as much as possible to reduce the possibility of flowing out of the first capillary hole 21e.

[0050] In some embodiments, the first capillary hole 21e communicates with the air inlet hole 10b, so that the first capillary hole 21e can also supply external gas, which can form a part of the air inlet channel to ensure the suction effect of the atomizer.

[0051] It should be noted that the specific size of the first capillary hole 21e can be determined according to actual conditions, which only needs to be able to form a liquid film under the action of surface tension to achieve a certain locking effect of the atomized liquid.

[0052] For example, the diameter of the first capillary hole 21e is greater than or equal to 0.4 mm and less than or equal to 0.6 mm. For example, 0.4 mm, 0.5 mm or 0.6 mm. By setting the diameter of the first capillary hole 21e in the above range, a better leakage prevention effect can be achieved.

[0053] The specific number of the first capillary hole 21e can be set according to actual conditions, for example, the liquid storage surface 21d has a plurality of first capillary holes 21e arranged at intervals.

[0054] The liquid storage surface 21d and the atomizer core 22 are in fluid communication through a liquid leakage path, wherein the liquid leakage path refers to a liquid flow path that can flow the leaked liquid from the atomizer core 22 to the liquid storage surface 21d. When the environment of the atomizer changes, the atomized liquid leaked from the oil tank 10a can flow to the atomizer core 22 along the liquid leakage path and then flow to the liquid storage surface 21d.

[0055] In the atomizer in the embodiments of the present application, the atomizing core 22 is at least partially arranged in the atomizing seat 21, the oil tank 10a and the atomizing core 22 are in fluid communication through a liquid supply path, the atomizing seat 21 has a liquid storage surface 21d, the atomizing core 22 is provided with the liquid storage surface 21d on at least one lateral side of the atomizing core 22, the liquid storage surface 21d extends to the atomizing core 22 on the side of the atomizing core 22, and the liquid storage surface 21d and the atomizing core 22 are in fluid communication through a liquid leakage path. In this way, by arranging the liquid storage surface 21d on at least one lateral side of the atomizing core 22, the atomizing liquid in the oil tank 10a can flow out of the liquid supply path due to negative pressure or temperature shock, and can be squeezed into the liquid storage surface 21d through the liquid leakage path. After the negative pressure is eliminated, the atomizing liquid in the liquid storage surface 21d can flow back to the oil tank 10a through the liquid leakage path and the liquid supply path in the reverse direction, thereby reducing the risk of liquid leakage. In addition, the liquid storage surface 21d has a first capillary hole 21e formed therethrough. In this way, the atomizing liquid squeezed into the liquid storage surface 21d during negative pressure or temperature shock can form a liquid film at the first capillary hole 21e. Under the action of the surface tension of the liquid film, the atomizing liquid in the liquid storage surface 21d can be locked in the liquid storage surface 21d, thereby realizing liquid sealing. After the negative pressure is eliminated, the atomizing liquid in the liquid storage surface 21d can flow back to the oil tank 10a along the liquid leakage path, thereby reducing the risk of atomizing liquid leakage.

[0056] In an embodiment, referring to Figure 3 and Figure 6 , the atomizing assembly 20 includes a ceramic silica gel 23, the ceramic silica gel 23 at least partially surrounds the atomizing core 22, the ceramic silica gel 23 is provided with the liquid storage surface 21d on at least one lateral side in the circumferential direction, and the ceramic silica gel 23 includes a first side wall close to the liquid storage surface 21d, the top surface of the first side wall is lower than or equal to the height of the liquid storage surface 21d. In this way, when the external negative pressure is eliminated, the leaked liquid collected in the liquid storage surface 21d can flow back to the oil tank 10a through the ceramic silica gel 23, and the effect of liquid backflow can be further improved.

[0057] Specifically, the ceramic silica gel 23 is arranged on the lateral side of the atomizing core 22. Under the action of suction, 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 for atomization by the atomizing core 22.

[0058] By arranging the liquid storage surface 21d on one or more lateral sides of the ceramic silica gel 23 in the circumferential direction, the atomizing liquid leaked into the liquid storage surface 21d under the action of negative pressure can flow back to the oil tank 10a through the ceramic silica gel 23 after the negative pressure is eliminated.

[0059] The atomizer in the related art can lock liquid by increasing the liquid absorbing cotton. In the case where the negative pressure disappears, the atomizing liquid that flows out is difficult to return to the oil tank, and there is a problem of reduction of the liquid level in the oil tank and the number of puffs.

[0060] In the embodiment, the first side wall of the ceramic silica gel 23 is the side wall on the same side of the liquid storage surface 21d of the ceramic silica gel 23. By making the top surface of the first side wall flush with the liquid storage surface 21d or making the top surface of the first side wall lower than the liquid storage surface 21d, the atomized liquid collected at the liquid storage surface 21d can flow smoothly to the ceramic silica gel 23, and then better return to the oil tank 10a, thereby improving the effect of liquid leakage return.

[0061] In an embodiment, the height of the liquid storage surface 21d is the same as the height of the atomization surface of the atomization core 22.

[0062] In fact, the atomization surface of the atomization core 22 is located on the top side of the atomization core 22. Therefore, by making the liquid storage surface 21d flush with the atomization surface of the atomization core 22, the atomization core 22 as a whole is lower than the liquid storage surface 21d, which can facilitate the return of the atomized liquid in the liquid storage surface 21d from the atomization core 22.

[0063] In an embodiment, referring to Figure 7 , Figure 8 and Figure 9 , the shell assembly 10 has an air inlet hole 10b, the atomization seat 21 includes an air exchange channel 21b, one end of the air exchange channel 21b communicates with the oil tank 10a, the other end of the air exchange channel 21b extends to the liquid storage surface 21d, the liquid storage surface 21d communicates with the air inlet hole 10b through a first capillary hole 21e, the air exchange channel 21b has an air exchange outlet 21ba extending to the liquid storage surface 21d, and the height of the air exchange outlet 21ba is the same as the height of the liquid storage surface 21d.

[0064] In fact, when the atomizer is provided with the air exchange channel 21b, when the environment of the atomizer changes, the atomized liquid in the oil tank 10a is also prone to flow out through the air exchange channel 21b under the action of negative pressure, causing the problem of liquid leakage. The atomizer of the embodiment can facilitate the atomized liquid in the liquid storage surface 21d to be squeezed back to the oil tank 10a through the air exchange channel 21b by the atmosphere when the external negative pressure is eliminated, thereby further improving the return effect of the atomized liquid.

[0065] In an embodiment, referring to Figure 7 , Figure 8 and Figure 9 , the liquid storage surface 21d has a plurality of liquid guide strips 211 protruding from at least a portion of the side of the liquid storage surface 21d close to the atomization core 22, and the liquid guide strips 211 are arranged at intervals to form capillary liquid guide grooves 21f at the intervals, and one end of the capillary liquid guide grooves 21f close to the atomization core 22 extends to the atomization core 22. Therefore, the atomized liquid in the liquid storage surface 21d can be collected in the capillary liquid guide grooves 21f, and when the external negative pressure is eliminated, the atomized liquid can better return through the atomization core 22.

[0066] Specifically, the liquid guide strips 211 are arranged on the liquid storage surface 21d, and the capillary liquid guide grooves 21f are formed between the adjacent liquid guide strips 211. The capillary liquid guide groove 21f has a capillary structure for collecting the atomized liquid. The atomized liquid leaked from the oil tank 10a into the liquid storage surface 21d can be collected in the capillary liquid guide groove 21f under the action of capillary force.

[0067] By extending the capillary liquid guide groove 21f to the atomizing core 22, when the external negative pressure is eliminated, the atomized liquid in the capillary liquid guide groove 21f can flow back to the oil tank 10a through the atomizing core 22 along the liquid leakage path and the liquid supply path under the action of atmospheric pressure. The capillary liquid guide groove 21f has a liquid guide effect, and the backflow effect of the atomized liquid can be improved.

[0068] It should be noted that the specific arrangement of the capillary liquid guide groove 21f is not limited. For example, one end of the capillary liquid guide groove 21f close to the atomizing core 22 extends to the atomizing core 22, and the other end of the capillary liquid guide groove 21f extends away from the atomizing core 22.

[0069] For another example, the liquid storage surface 21d includes a first region close to one side of the atomizing core 22 and a second region away from the other side of the atomizing core 22. The first region is provided with a plurality of liquid guide strips 211, and the second region is provided with a plurality of first capillary holes 21e.

[0070] In an embodiment, referring to Figure 6 and Figure 10 The atomizing seat 21 has a liquid inlet channel 21g. One end of the liquid inlet channel 21g is in communication with the oil tank 10a, and the other end of the liquid inlet channel 21g extends to the ceramic silica gel 23. At least one side of the ceramic silica gel 23 along the length direction is provided with the liquid inlet channel 21g, and at least one side of the ceramic silica gel 23 along the width direction is provided with the liquid storage surface 21d. In this way, the layout width of the liquid storage surface 21d can be increased, and the backflow of the atomized liquid in the liquid storage surface 21d can be facilitated.

[0071] Specifically, the oil tank 10a is in communication with the atomizing core 22 through the liquid inlet channel 21g.

[0072] The opposite sides of the ceramic silica gel 23 along the length direction are the opposite sides of the ceramic silica gel 23 along the long side, and the opposite sides of the ceramic silica gel 23 along the width direction are the opposite sides of the ceramic silica gel 23 along the short side.

[0073] By arranging the liquid storage surface 21d on one side or opposite sides of the ceramic silica gel 23 along the width direction, the liquid storage surface 21d can have a wider layout position, and the width of the joint between the liquid storage surface 21d and the atomizing core 22 can be increased, thereby facilitating the backflow of the atomized liquid in the liquid storage surface 21d.

[0074] In an embodiment, referring to Figure 5The shell assembly 10 has an air inlet hole 10b, and the atomizer further has a liquid leakage storage cavity 10c located at the bottom side of the liquid storage surface 21d, and the first capillary hole 21e communicates with the air inlet hole 10b through the liquid leakage storage cavity 10c. Thus, the risk of liquid leakage can be further reduced.

[0075] In fact, the liquid leakage storage cavity 10c is located on the communication path of the first capillary hole 21e and the air inlet hole 10b. Thus, even in some specific cases, such as in the process of negative pressure or temperature shock formed by the external environment, accompanied by violent vibration, part of the atomized liquid in the liquid storage surface 21d can break through the surface tension at the first capillary hole 21e under the action of inertial force, but it will not easily leak out of the air inlet hole 10b, but will be collected in the liquid leakage storage cavity 10c first, thereby further improving the anti-leakage performance of the atomizer.

[0076] In an embodiment, referring to Figure 5 , Figure 11 and Figure 12 , the liquid leakage storage cavity 10c includes a first sub-cavity 10ca, 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, the heating seat 214 is located at the bottom side of the heating top cover 213, the heating top cover 213 and the heating seat 214 form the first sub-cavity 10ca, part of the bottom wall of the first sub-cavity 10ca is penetrated to form a second capillary hole 10d, and the first capillary hole 21e, the first sub-cavity 10ca, the second capillary hole 10d and the air inlet hole 10b are sequentially communicated. Thus, the anti-leakage performance of the atomizer can be further improved.

[0077] Specifically, the first capillary hole 21e is formed at the top side of the first sub-cavity 10ca, so as to communicate with the first capillary hole 21e to collect the atomized liquid leaked from the first capillary hole 21e.

[0078] The bottom side of the first sub-cavity 10ca is formed with the second capillary hole 10d, which is a capillary hole structure with a small hole diameter. When the atomized liquid flows into the first sub-cavity 10ca, the atomized liquid can form a liquid film under the action of the surface tension at the second capillary hole 10d, so as to lock the atomized liquid in the first sub-cavity 10ca as much as possible, thereby reducing the possibility of flowing out of the second capillary hole 10d. At the same time, since the second capillary hole 10d communicates with the air inlet hole 10b, it can form part of the air inlet channel 122a to ensure the suction effect of the atomizer.

[0079] The first capillary hole 21e, the first sub-cavity 10ca, the second capillary hole 10d and the air inlet hole 10b are sequentially communicated, that is, the air inlet hole 10b and the first capillary hole 21e form an air inlet path sequentially passing through the second capillary hole 10d and the first sub-cavity 10ca.

[0080] In the related art, during the atomization process, suction will cause negative pressure in the atomizer. When the suction ends, due to the large aperture of the air outlet, air will quickly rush into the atomization cavity, causing part of the aerosol to be flushed out from the air inlet hole at the bottom of the atomizer, and to contact the SPCC at the bottom of the atomizer or the inner wall of the battery, and to condense and form condensation leakage when cold, affecting use.

[0081] In the atomizer of the present embodiment, the first sub-cavity 10ca is in communication with the liquid storage surface 21d through the first capillary hole 21e, and in communication with the air inlet hole 10b through the second capillary hole 10d. Therefore, when the suction ends, due to the slow passage of the first capillary hole 21e and the second capillary hole 10d, the pressure recovery is relatively late, causing the first sub-cavity 10ca to be a negative pressure area relative to the top side of the liquid storage surface 21d and the air inlet hole 10b. Atmospheric air rushes into the first sub-cavity 10ca from both ends through the first capillary hole 21e and the second capillary hole 10d, so that the remaining aerosol can be retained in the first sub-cavity 10ca, and will not be flushed out from the bottom of the atomizer through the air inlet hole 10b and hang on the outer wall of the atomizer, thereby reducing the risk of condensation leakage.

[0082] In a specific embodiment, the atomization seat 21 further comprises a top cover silica gel 212, which is located on the side of the heating top cover 213 away from the heating seat 214, and the heating top cover 213 and the top cover silica gel 212 together form the atomization cavity 21a, the air exchange channel 21b and the liquid storage cavity 21c. That is, the atomization cavity 21a, the air exchange channel 21b and the liquid storage cavity 21c are all formed by the heating top cover 213 and the top cover silica gel 212 together. The top cover silica gel 212 is located on the side of the heating top cover 213 close to the oil reservoir 10a, and the heating seat 214 is located on the side of the heating top cover 213 away from the oil reservoir 10a.

[0083] In an embodiment, referring to Figure 5 , Figure 11 , Figure 12 and Figure 13 , the liquid leakage storage cavity 10c further comprises a second sub-cavity 10cb, the shell assembly 10 comprises a shell main body 11 and an air inlet cover plate 12, the shell main body 11 has an oil reservoir 10a, the air inlet cover plate 12 has an air inlet hole 10b, at least part of the air inlet cover plate 12 and the atomization seat 21 are located in the shell main body 11, and the air inlet cover plate 12 is located on the side of the heating seat 214 away from the heating top cover 213, the air inlet cover plate 12 and the heating seat 214 together form the second sub-cavity 10cb, and the second capillary hole 10d is in communication with the second sub-cavity 10cb and the air inlet hole 10b.

[0084] Specifically, the second sub-cavity 10cb is located on the side of the second capillary hole 10d away from the first sub-cavity 10ca, and the second sub-cavity 10cb is formed by the air inlet cover plate 12 and the heating seat 214 together.

[0085] Therefore, by setting the second sub-cavity 10cb between the second capillary hole 10d and the air inlet hole 10b, in some specific cases, such as in the process of negative pressure or temperature shock of the external environment, even if part of the atomized liquid can pass through the first capillary hole 21e and the first sub-cavity 10ca and leak out from the second capillary hole 10d, it can be collected and stored in the second sub-cavity 10cb, which can reduce the risk of direct leakage from the air inlet hole 10b, thereby further improving the leakage prevention performance of the atomizer.

[0086] In an embodiment, referring to Figure 5 and Figure 13 , the liquid leakage storage cavity 10c further comprises a third sub-cavity 10cc, the air inlet cover plate 12 and the heating seat 214 form the second sub-cavity 10cb and the third sub-cavity 10cc, and part of the bottom wall of the air inlet cover plate 12 protrudes towards the side close to the heating seat 214 to form a first partition wall body 121 separating the second sub-cavity 10cb and the third sub-cavity 10cc, the bottom wall of the third sub-cavity 10cc has an air inlet hole 10b, and the first partition wall body 121 has a first air passage hole 121a, the first air passage hole 121a is in communication with the second sub-cavity 10cb and the third sub-cavity 10cc respectively, and the height of the first air passage hole 121a 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. Therefore, while not greatly affecting the air inlet effect, the leakage prevention performance of the atomizer can be further improved.

[0087] Specifically, in the enclosed space of the air inlet cover plate 12 and the heating seat 214, by setting the first partition wall body 121, the second sub-cavity 10cb and the third sub-cavity 10cc can be separated, wherein the second sub-cavity 10cb is in communication with the second capillary hole 10d, the third sub-cavity 10cc is in communication with the air inlet hole 10b, and the second sub-cavity 10cb and the third sub-cavity 10cc are in communication through the first air passage hole 121a on the first partition wall body 121.

[0088] It should be noted that the opening height of the first air passage hole 121a is above the bottom wall of the third sub-cavity 10cc and the bottom wall of the second sub-cavity 10cb, so that even if the atomized liquid passes through the first capillary hole 21e, the first sub-cavity 10ca, the second capillary hole 10d to the second sub-cavity 10cb in sequence, due to the higher opening height of the first air passage hole 121a, the atomized liquid can accumulate more in the second sub-cavity 10cb, thereby further reducing the risk of liquid leakage.

[0089] Among them, the third sub-cavity 10cc and the second sub-cavity 10cb are separated by the first partition wall body 121, and the specific separation method is not limited.

[0090] For example, the first partition wall 121 extends around the circumference of the air inlet hole 10b to enclose the third sub-cavity 10cc. That is, the third sub-cavity 10cc is located inside the first partition wall 121, and the second sub-cavity 10cb is located outside the first partition wall 121.

[0091] For another example, the first partition wall 121 encloses the second sub-cavity 10cb. That is, the second sub-cavity 10cb is located inside the first partition wall 121, and the third sub-cavity 10cc is located outside the first partition wall 121.

[0092] For yet another example, the first partition wall 121 and the sidewall of the air inlet cover plate 12 jointly enclose the second sub-cavity 10cb, and jointly enclose the third sub-cavity 10cc.

[0093] In an embodiment, referring to Figure 5 and Figure 13 the hole wall of the air inlet hole 10b is protruded towards the side close to the heating seat 214 to form a second partition wall 122, the second partition wall 122 encloses an air inlet passage 122a which is in communication with the air inlet hole 10b, the air inlet passage 122a has a second air passage hole 122b in communication with the third sub-cavity 10cc at the end away from the air inlet hole 10b, and the height of the second air passage hole 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. In this way, the risk of liquid leakage can be further reduced.

[0094] Specifically, the third sub-cavity 10cc is in communication with the air inlet passage 122a through the second air passage hole 122b, and in turn with the air inlet hole 10b. By extending the hole wall of the air inlet hole 10b towards the side close to the heating seat 214, the second air passage hole 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 through the first capillary hole 21e, the first sub-cavity 10ca, the second capillary hole 10d, the second sub-cavity 10cb, the first air passage hole 121a to the third sub-cavity 10cc in sequence, the higher height of the second air passage hole 122b can also make the atomized liquid accumulate more in the second sub-cavity 10cb and the third sub-cavity 10cc, thereby further reducing the risk of liquid leakage.
