A liquid through hole is provided at the top end of the housing, and the liquid through hole communicates the first cavity and the space inside the housing. At least a part of the liquid inlet that is not covered by the liquid storage member is exposed in the liquid through hole.

[0006] In some embodiments, the ratio of the area of the liquid inlet that is not covered to the area that is covered is 0.1 to 0.5.

[0007] In some embodiments, the atomization core includes an atomization sleeve, a liquid absorption member, and a heating member. The liquid inlet is provided on the side wall of the atomization sleeve. The liquid absorption member is arranged in the atomization sleeve and covers the liquid inlet. The heating member is stacked on the side of the liquid absorption member away from the liquid inlet;

[0008] Wherein, the heating member radially covers the first liquid inlet part exposed in the liquid through hole and the second liquid inlet part covered by the liquid storage member along the atomization sleeve.

[0009] In some embodiments, the heating member includes an upper heating mesh and a lower heating mesh that are axially distributed and connected along the atomization sleeve. The upper heating mesh covers the first liquid inlet part and a part of the second liquid inlet part, and the lower heating mesh covers the remaining second liquid inlet part.

[0010] In some embodiments, a cut groove is provided at one end of the liquid storage member facing the liquid through hole, and the bottom of the cut groove is not higher than the bottom of the upper heating mesh along the axial direction of the atomizing sleeve. The cut groove enables the liquid storage member to form a first surrounding portion around the upper heating mesh and a second surrounding portion around the lower heating mesh.

[0011] In some embodiments, the atomizing sleeve includes a first sleeve and a second sleeve. The second sleeve is sleeved inside the first sleeve and has an interference fit. The first sleeve is provided with a first liquid inlet, and the second sleeve is provided with a second liquid inlet. The first liquid inlet and the second liquid inlet overlap to form the liquid inlet. A ventilation groove communicating with the second liquid inlet is formed on the tube wall of the second sleeve;

[0012] Wherein, the inner wall surface of the first sleeve and the outer side surface of the liquid absorbing member respectively cover the inner and outer sides of the ventilation groove, and cooperate with the ventilation groove to form a ventilation channel, and the ventilation channel communicates the atmosphere with the second liquid inlet.

[0013] In some embodiments, two second liquid inlets spaced apart along the axial direction are provided on the tube wall of the second sleeve to respectively correspond to the upper heating mesh and the lower heating mesh. The ventilation groove communicates with the second liquid inlet corresponding to the upper heating mesh, and the second liquid inlet corresponding to the upper heating mesh is partially exposed in the liquid through hole.

[0014] In some embodiments, the size of the first liquid inlet along the circumferential direction of the first sleeve is smaller than the size of the second liquid inlet along the circumferential direction of the second sleeve.

[0015] In some embodiments, the first cavity is arranged around the second cavity, and the second cavity and the first cavity are separated by a tube body.

One end of the atomizing core extending out of the housing is connected to the movable member, and the housing is movably assembled in the second cavity;

[0018] When the atomizer assembly is assembled in the second cavity, the movable part avoids the connecting hole so that the connecting hole connects the first cavity and the second cavity; after the atomizer assembly is removed from the second cavity, the movable part blocks the connecting hole.

[0019] In order to solve the above technical problems, another technical solution adopted by the present application is to provide an electronic atomization device. The electronic atomization device comprises a host and the above-mentioned atomizer, wherein the host is connected to the atomizer and supplies power to the atomizer.

[0020] The beneficial effects of the present application are as follows: Different from the prior art, the present application discloses an electronic atomization device and an atomizer thereof. In the present application, a liquid inlet is provided on the side wall of the atomization core, and a portion of the liquid inlet is wrapped and covered by a liquid storage component, and the covered portion of the liquid inlet is supplied with liquid by the aerosol matrix absorbed by the liquid storage component; the portion of the liquid inlet not covered by the liquid storage component is at least exposed in the liquid through hole, so that the liquid is directly supplied by the liquid aerosol matrix at the liquid through hole; thus, the liquid inlet has two liquid supply paths, among which the liquid supply rate from the liquid storage component to the atomization core is relatively more balanced, and a more uniform and appropriate amount of aerosol matrix can be provided to the atomization core to meet the basic atomization demand of the atomization core. Once the atomization demand of the atomization core is too high due to the influence of the user's smoking habits, and it cannot be met due to the nature of the liquid storage component, dry burning is likely to occur; an additional liquid supply path is provided in the present application, That is, the aerosol matrix at the liquid through hole can relatively more quickly supply liquid to the uncovered part of the liquid inlet for atomization of the atomizer core, so as to increase the liquid supply demand to the atomizer core in real time, make up for the part of the atomization demand that cannot be met by the liquid storage component, and prevent the atomizer core from dry burning due to insufficient liquid supply. When the atomizer is in use, the uncovered part of the liquid inlet is relatively located at the top, and the aerosol matrix entering the atomizer core from there is affected by gravity, which can increase the rate of liquid supply from top to bottom to the heating element in the atomizer core, and avoid dry burning of the heating element relatively located at the bottom; therefore, the atomizer provided by the present application can effectively reduce the risk of the atomizer having an unpleasant taste due to dry burning, and can effectively improve the reliability of its atomization performance.

[0033] The present application provides an electronic atomization device 300. Refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the electronic atomization device provided by the present application.

[0034] The electronic atomization device 300 includes a main unit 200 and an atomizer 100. The main unit 200 is connected to the atomizer 100 and supplies power to the atomizer 100.

[0035] The electronic atomization device 300 can be used for atomizing aerosol matrices such as e-liquid, liquid medicine, or nutrient solution, that is, atomizing the liquid aerosol matrix to form an aerosol for the user to inhale. Among them, the main unit 200 can be detachably connected to the atomizer 100 and supply power to the atomizer 100, so that the atomizer 100 can be replaced; or the main unit 200 and the atomizer 100 are integrally structured and supply power to the atomizer 100. The atomizer 100 is used to store the aerosol matrix and atomize the aerosol matrix to form an aerosol for the user to absorb.

[0036] The main unit 200 includes a control element and a battery that are electrically connected. The control element is also used to be electrically connected to the atomizer 100 to identify the status information of the atomizer 100 and control the power supply to the atomizer 100 according to the identified status information.

[0037] Please refer to Figures 2 to 4 , Figure 2 which is Figure 1 a schematic structural diagram of an embodiment of the atomizer in the electronic atomization device shown, Figure 3 which is Figure 2 a schematic structural diagram of the separated state of the housing assembly and the atomization assembly in the atomizer shown, Figure 4 which is Figure 2 a schematic structural diagram of the atomization assembly in the atomizer shown.

[0038] As shown in Figure 2 and Figure 4As shown, the atomizer 100 includes a housing assembly 10 and an atomization assembly 2. A first cavity 101 and a second cavity 102 that are in communication with each other are formed in the housing assembly 10. The first cavity 101 is used for storing an aerosol matrix; the atomization assembly 2 is assembled in the second cavity 102 and includes a housing 20, a liquid storage member 30, and an atomization core 40. The atomization core 40 is installed in the housing 20. The liquid storage member 30 is disposed in the housing 20 and is arranged around the atomization core 40. The liquid storage member 30 also covers a liquid inlet 401 on the side wall of a part of the atomization core 40. A liquid through hole 201 is provided at the top end of the housing 20. The liquid through hole 201 communicates the first cavity 101 and the space inside the housing 20. At least a part of the liquid inlet 401 not covered by the liquid storage member 30 is exposed in the liquid through hole 201.

[0039] In the housing assembly 10, the first cavity 101 is used for storing an aerosol matrix, and the second cavity 102 is at least used for assembling the atomization assembly 2. Among them, the first cavity 101 can be arranged around the second cavity 102, or the first cavity 101 and the second cavity 102 are arranged side by side.

[0040] In this embodiment, the first cavity 101 is arranged around the second cavity 102. The second cavity 102 and the first cavity 101 are separated by a tube body 104. The tube body 104 is provided with a communication hole 103 that communicates the first cavity 101 and the second cavity 102.

[0041] Specifically, referring to Figure 3 , the housing assembly 10 includes a housing 12 and a base 14. One end of the housing 12 has a mouthpiece 120, and the other end is an open end. The base 14 includes a base body 140 and a tube body 104 connected to the base body 140. The cavity formed by the communication between the base body 140 and the tube body 104 together constitutes the second cavity 102. The base body 140 is hermetically connected to the open end of the housing 12. One end of the tube body 104 away from the base body 140 is hermetically connected to the mouthpiece 120.

[0042] Optionally, the first cavity 101 and the second cavity 102 can be arranged side by side. For example, the space inside the housing 12 is separated by a partition to form the first cavity 101 and the second cavity 102. The partition is provided with a communication hole 103 that communicates the first cavity 101 and the second cavity 102.

[0043] Among them, the atomization assembly 2 is detachably installed in the second cavity 102. For example, the atomization assembly 2 can be inserted, snapped, or screwed into the second cavity 102.

[0044] In this embodiment, the atomization assembly 2 is movably embedded in the second cavity 102 to facilitate the disassembly and assembly of the atomization assembly 2 from the housing assembly 10.

[0045] Optionally, the liquid through hole 201 on the shell 20 can be directly connected to the connecting hole 103, that is, the aerosol matrix in the first cavity 101 can directly supply liquid to the space in the shell 20. For example, an inclined surface is formed on the inner side of the tube body 104, and the connecting hole 103 is a hole on the inclined surface. The top end of the shell 20 also forms a corresponding inclined surface and fits on the inclined surface on the inner side of the tube body 104, wherein the liquid through hole 201 is also connected to the connecting hole 103.

[0046] In this embodiment, Figure 2 As shown, after the atomizer assembly 2 is embedded in the second cavity 102, the second cavity 102 is not completely occupied, and a portion of the space is left as a transition cavity 106 to communicate with the second cavity 102.

[0047] The first cavity 101 and the liquid through hole 201 of the housing 20, that is, the connecting hole 103 and the liquid through hole 201 are both connected to the transition cavity 106, and the transition cavity 106 is a part of the second cavity 102, that is, the liquid through hole 201 is connected to the second cavity 102. The aerosol matrix in the first cavity 101 enters the housing 20 through the connecting hole 103, the transition cavity 106 and the liquid through hole 201.

[0048] Furthermore, a conical surface 105 is formed on the end surface of the second cavity 102 facing the outer shell 20. The conical surface 105 allows the liquid in the second cavity 102 to flow back to the first cavity 101 through the connecting hole 103 when the atomizer 100 is inverted. Therefore, when the atomizer 100 is inverted to replace the atomization component 2, the stored liquid in the transition cavity 106 can avoid leakage by flowing back to the first cavity 101, thereby reducing the risk of leakage.

[0049] like Figure 2 and Figure 3 As shown, the housing assembly 10 further includes a movable member 16 movably disposed in the second cavity 102. The movable member 16 has a conical surface 105 at one end thereof facing the atomizer assembly 2. The atomizer core 40 extends out of the housing 20 at one end thereof and is connected to the movable member 16. The housing 20 is movably assembled in the second cavity 102. Please refer to Figure 2 , wherein the movable member 16 avoids the connecting hole 103 when the atomizer assembly 2 is assembled in the second cavity 102, so that the connecting hole 103 connects the first cavity 101 and the second cavity 102; please refer to Figure 3 After the atomizer assembly 2 is removed from the second cavity 102 , the movable member 16 blocks the communicating hole 103 .

[0050] The second cavity 102 is a straight cylindrical cavity. By installing the atomization component 2 into the second cavity 102 and removing the atomization component 2 from the second cavity 102, the user can simultaneously drive the movement of the movable member 16. When the movable member 16 moves to the first position, it can avoid the communication hole 103. When the movable member 16 moves to the second position, it can block the communication hole 103 to prevent the aerosol matrix in the first cavity 101 from leaking through the communication hole 103.

[0051] Specifically, in the scenario of installing the atomization component 2 into the second cavity 102, initially, the movable member 16 is located at the second position and blocks the communication hole 103. Then, the atomization component 2 is pushed inward from the port of the second cavity 102. The atomization core 40 will push the movable member 16 to move from the second position to the first position. One end of the atomization core 40 is also connected to the movable member 16. The atomization channel of the atomization core 40 leads to the mouthpiece 120 through the movable member 16, and a transition cavity 106 is formed between the movable member 16 and the housing 20. In the scenario of removing the atomization component 2 from the second cavity 102, the aerosol matrix in the transition cavity 106 is guided by the conical surface 105 of the movable member 16 and then flows back into the first cavity 101 through the communication hole 103. The user applies force to pull the atomization component 2 outward. At the same time, the atomization component 2 drives the movable member 16 to move outward together, so that the movable member 16 moves from the first position to the second position and blocks the communication hole 103, preventing the aerosol matrix in the first cavity 101 from leaking, and at the same time separating the atomization core 40 and the movable member 16.

[0052] By further arranging the movable member 16 in the second cavity 102, the movable member 16 can move with the atomization component 2. Thus, when the atomization component 2 is removed, the communication hole 103 can be blocked to prevent the aerosol matrix in the first cavity 101 from leaking. When the atomization component 2 is installed in the second cavity 102, the communication hole 103 can be avoided to facilitate the aerosol matrix in the first cavity 101 to enter the transition cavity 106 and supply liquid to the atomization component 2.

[0053] In this embodiment, as Figure 3 shown, the movable member 16 includes a movable cylinder body 160 and a conical end 162 connected to one end of the movable cylinder body 160. The movable cylinder body 160 is movably assembled with the inner wall surface of the second cavity 102. The conical surface 105 of the conical end 162 faces the outer surface of the housing 20. A liquid collecting groove 164 is formed on the inner surface of the conical end 162. A liquid collecting member 17 is arranged in the movable cylinder body 160 and on the liquid collecting groove 164. The liquid collecting member 17 is provided with an aerosol channel 170 communicating with the atomization channel 401 of the atomization core 40.

[0054] A sealing ring may be provided on the outer wall of the movable cylinder body 160, and the sealing ring also abuts against the inner wall surface of the second cylinder body 102, so that the movable member 16 and the inner wall surface of the second cylinder body 102 form a movable matching relationship, that is, when no external force is applied to the movable member 16, the position of the movable member 16 remains unchanged relative to the second cavity 102, and when an external force is applied to the movable member 16, the movable member 16 can be driven to move in the second cavity 102.

[0055] The conical end 162 has a port that mates with the end of the atomization core 40, and one end of the atomization core 40 is sealingly connected to the conical end 162 to prevent liquid leakage. A liquid collecting member 17 that can adsorb condensate is provided in the movable member 16. The liquid collecting member 17 can be made of a liquid-absorbing material such as cotton or non-woven fabric. It can adsorb the condensate formed by the aerosol rising and condensing when encountering cold, which can prevent the taste of the aerosol from deteriorating due to the condensate entering the user's mouth, and can also prevent the condensate from flowing back to the atomization core 40, effectively improving the atomization performance of the atomizer 100.

[0056] When the liquid collecting member 17 adsorbs a large amount of condensate, the condensate can gather in the liquid collecting groove 164 of the conical end 162 under the influence of gravity, that is, the liquid collecting groove 164 can be used to collect condensate, further improving the liquid collecting ability.

[0057] Continue to refer to Figures 3 to 5 , where Figure 5 is Figure 4 an exploded structural schematic diagram of the atomization assembly shown. The housing 20 includes a cylinder body 220 and a base 222. A liquid through hole 201 is provided at the top end of the cylinder body 220, and its bottom end is an open end. The base 222 seals the open end of the cylinder body 220 and defines an accommodation cavity. The liquid storage member 30 is arranged in the accommodation cavity. The atomization core 40 is connected to the base 222 and the top end of the cylinder body 220. An air hole communicating with the atomization core 40 is provided on the base 122.

[0058] Specifically, the liquid through hole 201 includes a connecting portion 202 and a liquid through portion 203 provided on at least one side of the connecting portion 202. Both the connecting portion 202 and the liquid through portion 203 are hole structures penetrating the top end of the cylinder body 220. Among them, the connecting portion 202 and the atomization core 40 are in shaft hole fit, and the liquid through portion 203 communicates the accommodation cavity inside the housing 20 and the transition cavity 106 outside the housing 20.

[0059] In this embodiment, liquid through portions 203 are symmetrically provided on both sides of the connecting portion 202, and the ratio of the area of the liquid through portion 203 to the area of the end portion of the liquid storage member 30 is 0.25 to 0.5, so as to replenish the liquid storage member 30 in the accommodation cavity more quickly and evenly.

[0060] Among them, the ratio of the area of the liquid through portion 203 to the area of the end portion of the liquid storage member 30 can be 0.25, 0.3, 0.35, 0.4, 0.45 or 0.5.

[0061] The length of the liquid inlet 401 along the circumferential direction of the outer wall of the atomization core 40 is less than the length of the side wall of the connecting portion 202 in the same circumferential direction. The exposed part of the liquid inlet 401 on the atomization core 40 is located at the liquid passing portion 203. This part of the liquid inlet 401 can face the liquid passing portion 203, and it can also face the side wall of the connecting portion 202. When facing the side wall of the connecting portion 202, the space of this part of the liquid inlet 401 is still connected to the space of the liquid passing portion 203, and this part of the liquid inlet 401 can still directly accumulate the aerosol matrix.

[0062] The material of the liquid storage member 30 can be polyester fiber, polypropylene fiber, non-woven fabric, etc. It has high adsorption capacity and uniform adsorption capacity, can absorb and store a certain amount of aerosol matrix, and it also has good liquid guiding ability and stable liquid guiding rate to ensure that the aerosol matrix can be smoothly transmitted to the atomization core 40.

[0063] The liquid storage member 30 is arranged in the accommodation cavity of the outer shell 20, can absorb and store the aerosol matrix and conduct the aerosol matrix to the atomization core 40. Its function is to appropriately block the fluidity of the aerosol matrix, prevent too much and too fast aerosol matrix from entering the atomization core 40 and causing liquid leakage accidents, and can also reduce the liquid leakage risk at each connection of the outer shell 20.

[0064] Refer to in combination with Figure 2 and Figure 4 , at least a part of the liquid inlet 401 of the atomization core 40 is exposed in the liquid passing hole 201, or further, this part of the liquid inlet 401 can be exposed in the liquid passing hole 201 and the transition cavity 106. This exposed part of the liquid inlet 401 is not covered by the liquid storage member 30, so the aerosol matrix at the liquid passing hole 201 can directly supply liquid to it. Compared with the path where the aerosol matrix needs to pass through the liquid storage member 30 to supply liquid to the liquid inlet 401, its liquid supply rate is higher and it can more quickly supplement the insufficient liquid supply demand of the atomization core 40.

[0065] In this application, a liquid inlet 401 is provided on the side wall of the atomization core 40. Part of the liquid inlet 401 is wrapped and covered by the liquid storage member 30, and the covered part of the liquid inlet 401 is supplied with liquid by the aerosol matrix absorbed and stored by the liquid storage member 30; the part of the liquid inlet 401 not covered by the liquid storage member 30 is at least exposed in the liquid through-hole 201 to be directly supplied with liquid by the liquid aerosol matrix temporarily stored at the liquid through-hole 201. Therefore, the liquid inlet 401 has two relatively liquid supply paths. Among them, the liquid supply rate from the liquid storage member 30 to the atomization core 40 is relatively more balanced, and a more uniform and appropriate amount of aerosol matrix can be provided to the atomization core 40 to meet the basic atomization requirements of the atomization core 40. However, once the atomization demand of the atomization core 40 is too high due to the influence of the user's suction habit and cannot be met due to the nature limitation of the liquid storage member 30, dry burning is likely to occur; in this application, an additional liquid supply path is provided, that is, the aerosol matrix at the liquid through-hole 201 can relatively supply liquid to the uncovered part of the liquid inlet 401 more quickly for the atomization core 40 to atomize, so as to improve the liquid supply demand to the atomization core 40 in real time, make up for the part of the atomization demand that cannot be met by the liquid storage member 30, and prevent dry burning of the atomization core 40 caused by insufficient liquid supply. When the atomizer 100 is in use, the uncovered part of the liquid inlet 401 is relatively located above, and the aerosol matrix entering the atomization core 40 from this place is affected by gravity, which can increase the liquid supply rate from top to bottom to the heating element in the atomization core 40 and avoid dry burning of the part of the heating element relatively located at the bottom.

[0066] Further, the ratio of the uncovered area to the covered area of the liquid inlet 401 is 0.1 to 0.5 to balance the liquid supply capabilities of the two liquid replenishment paths, so that the liquid supply rate to the atomization core 40 can be increased without increasing the risk of liquid leakage, thereby effectively reducing the risk of dry burning of the atomization core 40.

[0067] Specifically, the ratio of the uncovered area to the covered area of the liquid inlet 401 can be 0.1, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45 or 0.5. Among them, if the ratio of the uncovered area to the covered area of the liquid inlet 401 is less than 0.1, the effect of increasing the liquid supply rate to the atomization core 40 will not be significant enough; if the ratio of the uncovered area to the covered area of the liquid inlet 401 is greater than 0.5, the risk of liquid leakage of the atomization core 40 will increase and the atomization of the overly sufficient aerosol matrix will be insufficient.

[0068] Please refer to Figure 3 、 Figure 4 and Figure 6 where Figure 6 is Figure 4 a schematic cross-sectional structure diagram of the atomization core in the shown atomization assembly.

[0069] The atomizer core 40 includes an atomizer sleeve 41, a liquid suction component 42 and a heating component 43. The side wall of the atomizer sleeve 41 is provided with a liquid inlet 401. The liquid suction component 42 is arranged in the atomizer sleeve 41 and covers the liquid inlet 401. The heating component 43 is stacked on the side of the liquid suction component 42 away from the liquid inlet 401; wherein the heating component 43 covers the first liquid inlet portion 402 exposed in the liquid hole 201 and the second liquid inlet portion 403 covered by the liquid storage component 30 along the radial direction of the atomizer sleeve 41.

[0070] The atomizing sleeve 41 is a tubular structure, which can be a single-tube structure or a multi-layer tube structure, with at least one liquid inlet 401 distributed along its circumference, and multiple liquid inlets 401 can be evenly distributed along the axial direction of the atomizing sleeve 41. The liquid absorbing member 42 can be made of cotton or non-woven fabric, etc., which can absorb liquid and guide the liquid to the heating member 43; or the liquid guiding member 42 can also be porous ceramic or porous glass. The heating member 42 can be a heating net or a heating film, which can heat the atomized aerosol matrix to generate aerosol in the atomizing channel 401.

[0071] Among them, the heating element 43 covers the liquid inlet 401 along the radial direction of the atomizing sleeve 41, and the liquid inlet 401 is divided into a first liquid inlet portion 402 exposed in the liquid hole 201 and a second liquid inlet portion 403 covered by the liquid storage component 30. The heating element 43 covers the first liquid inlet portion 402 and the second liquid inlet portion 403 at the same time. Within a unit area, the liquid inlet rate at the first liquid inlet portion 402 is greater than the liquid inlet rate at the second liquid inlet portion 403. The first liquid inlet portion 402 is relatively located at the top and has a larger liquid inlet rate. It can supply liquid to the heating element 43 more quickly, and under the influence of gravity, it can supply liquid to the entire downward liquid absorption component 42 and the heating element 43, so as to assist in strengthening the liquid supply to the portion of the heating element 43 located at the bottom, thereby reducing the risk of dry burning of the portion of the heating element 43 at the bottom.

[0072] In this embodiment, Figure 3 and Figure 6 As shown, the heating element 43 includes an upper heating net 431 and a lower heating net 432 distributed and connected along the axial direction of the atomizing sleeve 41 , the upper heating net 431 covers the first liquid inlet portion 402 and part of the second liquid inlet portion 403 , and the lower heating net 432 covers the rest of the second liquid inlet portion 403 .

[0073] The heating element 43 is a heating net with two layers, upper and lower. If the upper heating net 431 and the lower heating net 432 are both supplied with liquid by the aerosol matrix absorbed by the liquid storage component 30, the liquid supply to the upper heating net 431 may be relatively less due to factors such as gravity, which may easily cause insufficient liquid supply to the upper heating net 431, resulting in a greater risk of dry burning of the upper heating net 431.

[0074] In this embodiment, the aerosol matrix at the liquid through-hole 201 can supply liquid to the upper heating mesh 431 more directly through the first liquid inlet 402 at a faster rate. The aerosol matrix can flow to the upper heating mesh 431 more quickly. The aerosol matrix absorbed by the liquid storage member 30 relatively below can supply liquid to the lower heating mesh 432, so that both the upper heating mesh 431 and the lower heating mesh 432 can be sufficiently supplied with liquid, and the two different liquid supply paths can effectively reduce the liquid robbing phenomenon between the upper heating mesh 431 and the lower heating mesh 432.

[0075] Optionally, as Figure 5 shown, the liquid storage member 30 can be cylindrical, and is provided with a through-hole for the atomization core 40 to pass through. The liquid storage member 30 basically occupies the accommodation cavity of the outer shell 20.

[0076] Please refer to Figure 7 , Figure 7 is Figure 2 a schematic structural diagram of another embodiment of the atomization assembly in the atomizer shown. Optionally, a cut groove 301 is provided at one end of the liquid storage member 30 facing the liquid through-hole 201. The bottom of the cut groove 301 is not higher than the bottom of the upper heating mesh 431 along the axial direction of the atomization sleeve 41. The cut groove 301 makes the liquid storage member 30 form a first surrounding portion 31 surrounding the upper heating mesh 431 and a second surrounding portion 32 surrounding the lower heating mesh 432.

[0077] The cut groove 301 is provided at the outer edge of the liquid storage member 30. By providing the cut groove 301, the aerosol matrix can directly reach the inside of the liquid storage member 30. The aerosol matrix can directly reach the lower heating mesh 432 through the second surrounding portion 32, relatively shortening the path for the aerosol matrix to reach the lower heating mesh 431 and improving the liquid supply efficiency to the lower heating mesh 432; the aerosol matrix passing through the first surrounding portion 31 can supply liquid to at least part of the upper heating mesh 431, and the aerosol matrix therein can also supply liquid to the lower heating mesh 432 through the second surrounding portion 32.

[0078] By further providing the cut groove 301 on the liquid storage member 30, different lengths of liquid supply paths can be formed for the heating meshes at different positions, so as to take into account the liquid supply requirements of the heating mesh structures at various positions, balance and ensure the liquid supply requirements of the heating meshes at various positions, eliminate the liquid supply imbalance phenomenon of excessive or insufficient liquid supply at local positions, so that each position of the heating member 43 can be supplied with liquid in a timely and sufficient manner and leakage can also be avoided.

[0079] Please refer to Figure 6 and Figure 8 , where Figure 8 is Figure 6 an exploded structural diagram of the atomization sleeve in the atomization core shown.

[0080] The atomization sleeve 41 includes a first sleeve 411 and a second sleeve 412. The second sleeve 412 is sleeved inside the first sleeve 411 and has an interference fit. The first sleeve 411 is provided with a first liquid inlet 413, and the second sleeve 412 is provided with a second liquid inlet 414. The first liquid inlet 413 and the second liquid inlet 414 overlap to form a liquid inlet 401. A ventilation groove 415 is formed on the tube wall of the second sleeve 412. Wherein, the inner wall surface of the first sleeve 411 and the outer side surface of the liquid absorption member 42 respectively cover the inner and outer sides of the ventilation groove 415, and cooperate with the ventilation groove 415 to form a ventilation channel, and this ventilation channel communicates the atmosphere with the second liquid inlet 414.

[0081] Specifically, this ventilation channel communicates with the atomization channel 401 of the atomization core 40, and can supplement air into the first cavity 101 through the ventilation channel when the air pressure in the first cavity 101 is unbalanced, so as to avoid insufficient liquid supply caused by too low air pressure in the first cavity 101 and losing the liquid supply ability to the atomization core 40.

[0082] The ventilation groove 415 is a through groove on the tube wall of the second sleeve 412, that is, it penetrates through the tube wall of the second sleeve 412. Therefore, the process of forming the ventilation groove 415 on the tube wall of the second sleeve 412 is simple, the processing efficiency is high, and the processing time is greatly saved and the processing efficiency is improved.

[0083] By setting the atomization sleeve 41 into the first sleeve 411 and the second sleeve 412 that can be in interference fit, the ventilation groove 415 can be conveniently formed on the second sleeve 412, and through the cooperation with the inner wall surface of the first sleeve 411 and the outer side surface of the liquid absorption member 42, a ventilation channel for air supplement can be formed. Compared with directly processing the ventilation groove 415 on the atomization base, the scheme of forming the ventilation channel adopted in this application has higher processing efficiency and lower cost.

[0084] The ventilation groove 415 is arranged on the second sleeve 412 and covered by the liquid absorption member 42, which can effectively avoid the situation that the air supplement effect is poor due to the ventilation groove 415 being filled with the liquid aerosol matrix.

[0085] In this embodiment, a ventilation groove 415 communicating with the second liquid inlet 414 is formed on the tube wall of the second sleeve 412, that is, one end port of the ventilation groove 415 directly communicates with the second liquid inlet 414, and the ventilation channel directly supplements air through the second liquid inlet 414, which can greatly improve its air supplement efficiency and reduce the air supplement difficulty.

[0086] Optionally, the ventilation groove 415 is isolated from the second liquid inlet 414, and air exchange is carried out through the liquid absorption member 42. That is, the ventilation groove 415 is not directly communicated with the second liquid inlet 414, and the ventilation channel still needs to rely on the liquid absorption member 42 to supplement air into the first cavity 101. The inside of the liquid absorption member 42 is a pore structure, and the entered gas supplements air into the first cavity 101 along its pores.

[0087] Furthermore, both the first sleeve 411 and the second sleeve 412 are rigid tubes, which can effectively prevent the occurrence of events where the ventilation effect is impaired due to the deformation of the ventilation channel, and can better maintain the stability of the ventilation channel.

[0088] A plurality of liquid inlets 401 may be spaced apart along the circumferential direction of the atomizing sleeve 41. For each liquid inlet 401, it includes a first liquid inlet 413 and two second liquid inlets 414 corresponding to the first liquid inlet 413. The two second liquid inlets 414 are axially spaced apart along the tube wall of the second sleeve 412 and respectively correspond to the upper heating mesh 431 and the lower heating mesh 432. Among them, the ventilation groove 415 communicates with the second liquid inlet 414 corresponding to the upper heating mesh 431, and the second liquid inlet 414 corresponding to the upper heating mesh 431 is partially exposed in the liquid through hole 201. Thus, the aerosol matrix at the liquid through hole 201 can quickly flow upward to the upper heating mesh 431 through the second liquid inlet 414 for atomization by the upper heating mesh 431, and the liquid storage member 30 can supply liquid to the lower heating mesh 432 through the second liquid inlet 414 below. Therefore, it not only avoids dry burning of the upper heating mesh 431 but also avoids liquid robbing between the upper heating mesh 431 and the lower heating mesh 432.

[0089] In this embodiment, the ventilation groove 415 communicates with the second liquid inlet 414 corresponding to the upper heating mesh 431, which can greatly shorten the path from the port of the ventilation groove 415 to the liquid through hole 201, making the air supplement smoother and reducing the attenuation effect of the liquid storage member 30 on the air supplement effect.

[0090] Furthermore, the size of the first liquid inlet 413 along the circumferential direction of the first sleeve 411 is smaller than the size of the second liquid inlet 414 along the circumferential direction of the second sleeve 412, and the aerosol matrix flows to the liquid absorption member 42 only through the first liquid inlet 413 and then the second liquid inlet 414 in sequence. By setting the relatively smaller-diameter first liquid inlet 413, the too-fast conduction rate of the aerosol matrix can be effectively restricted, so that it has an appropriate liquid conduction rate.

[0091] The second sleeve 412 is provided with multiple groups of second liquid inlets 414 along the circumferential direction. The ventilation groove 415 is arranged between adjacent two groups of second liquid inlets 414. The ventilation groove 415 includes a first ventilation section 416 and a second ventilation section 417 that are connected. The first ventilation section 416 communicates with one side of the second liquid inlet 414 in the circumferential direction, and the second ventilation section 417 extends axially along the second sleeve 412 to between the bottom of the second liquid inlet 414 corresponding to the lower heating mesh 431 and the end of the second sleeve 412.

[0092] By defining the position and path of the air exchange groove 415 as described above, it can effectively shorten the air supplement path and improve the air supplement efficiency. At the same time, the end of the second air exchange section 417 far from the first air exchange section 416 is between the bottom of the second liquid inlet 414 and the end of the second sleeve 412, and does not directly cut off the end of the second sleeve 412. Therefore, the second sleeve 412 can still maintain relatively good structural strength and avoid deformation, and can effectively maintain the stability of the air supplement channel.

[0093] Different from the prior art, the present application discloses an electronic atomization device and its atomizer. A liquid inlet is provided on the side wall of the atomization core in the present application, and a part of the liquid inlet is wrapped and covered by a liquid storage member. The covered part of the liquid inlet is supplied with liquid by the aerosol matrix absorbed by the liquid storage member; the part of the liquid inlet not covered by the liquid storage member is at least exposed in the liquid through hole to be directly supplied with liquid by the liquid aerosol matrix at the liquid through hole; therefore, the liquid inlet relatively has two liquid supply paths, and the liquid supply rate from the liquid storage member to the atomization core is relatively more balanced, and a more uniform and appropriate amount of aerosol matrix can be provided to the atomization core to meet the basic atomization requirements of the atomization core. However, once the atomization demand of the atomization core is too high due to the influence of the user's suction habit and cannot be met due to the nature of the liquid storage member, dry burning is likely to occur; in the present application, an additional liquid supply path is provided, that is, the aerosol matrix at the liquid through hole can relatively supply liquid to the uncovered part of the liquid inlet more quickly for atomization of the atomization core, so as to timely increase the liquid supply demand to the atomization core and make up for the part of the atomization demand that cannot be met by the liquid storage member, preventing dry burning of the atomization core due to insufficient liquid supply. When the atomizer is in use, the uncovered part of the liquid inlet is relatively located above, and the aerosol matrix entering the atomization core from this place is affected by gravity, which can increase the liquid supply rate from top to bottom to the heating element in the atomization core and avoid dry burning of the part of the heating element relatively located at the bottom.

[0094] The above are only the embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
