[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The terms "first", "second", "third" in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0044] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] The present application provides an electronic atomization device 300, see Figures 1 to 4 , Figure 1 is a structural schematic diagram of an embodiment of an electronic atomization device provided by the present application, Figure 2 yes Figure 1 The schematic diagram of the structure of an embodiment of an atomizer in an electronic atomization device is shown. Figure 3 yes Figure 2 The cross-sectional structure diagram of the atomizer along the BB direction is shown. Figure 4 yes Figure 2 Schematic diagram of the explosion structure of the atomizer shown.

[0046] like Figure 1 As shown, the electronic atomization device 300 can be used for atomization of cigarette oil. Figure 1As shown, the electronic atomization device 300 includes an atomizer 100 and a power supply assembly 200 which are interconnected. The atomizer 100 is used to store liquid and atomize the liquid to form smoke that can be inhaled by the user. The liquid can be a liquid matrix such as smoke liquid or medicine liquid. The power supply assembly 200 is used to supply power to the atomizer 100 so that the atomizer 100 can atomize the liquid matrix to form smoke.

[0047] like Figures 2 to 4 As shown, the atomizer 100 may include a cartridge tube 10 , a base 20 , an atomizer core 30 and a base 40 , wherein the atomizer core 30 is disposed between the base 20 and the base 30 , and the base 20 , the atomizer core 30 and the base 40 are accommodated in the cartridge tube 10 .

[0048] In this embodiment, a liquid storage chamber 12 and a smoke passage 14 are provided in the smoke cartridge tube 10, and a liquid outlet 16 is formed at one end of the smoke cartridge tube 10, and the liquid outlet 16 is connected to the liquid storage chamber 12. The liquid storage chamber 12 is used to store smoke liquid, and the smoke passage 14 is used to send the converted smoke out from the smoke passage 14.

[0049] Combined with reference Figures 2 to 5 The base 20 is embedded in the cigarette cartridge tube 10 and covers the liquid outlet 16. The base 20 may include a guide portion 22 and a receiving portion 26 connected in sequence. The guide portion 22 is provided with a liquid inlet hole 222 and an air outlet hole 224. The liquid storage chamber 12 is in fluid communication with the liquid inlet hole 222, and the smoke channel 14 is in fluid communication with the air outlet hole 224. The receiving portion 26 is formed with a receiving cavity 262 for receiving part of the atomizer core 30, and the atomizer core 30 is partially received in the receiving cavity 262. The receiving portion 26 is in communication with the guide portion 22 and cooperates with the first surface 321 of the atomizer core 30, thereby connecting the liquid inlet hole 222 with the atomizer core 30, so that the smoke liquid in the liquid inlet hole 222 can be transported to the atomizer core 30 through the guide portion 22. The atomizer core 30 is used to convert the delivered smoke liquid into smoke by generating heat. The air outlet 224 is fluidically connected to the atomizer core 30 to transfer the converted smoke from the air outlet 224 to the smoke channel 14 . The smoke is guided to the user's mouth through the smoke channel 14 .

[0050] In this embodiment, a liquid inlet hole 222 and an air outlet hole 224 are provided on the end surface of the base 20 close to the liquid storage chamber 12. The liquid inlet hole 222 connects the two opposite end surfaces of the guide portion 22, so that the smoke liquid in the liquid storage chamber 12 flows into the atomizer core 30 through the liquid inlet hole 222; the air outlet hole 224 connects the end surface and the side surface of the guide portion 22, and the atomized smoke flows into the side surface of the guide portion 22 along with the air flow, and further flows out through the air outlet hole 224 and the smoke channel 14.

[0051] In this embodiment, the base 20 having the liquid inlet 222 and the air outlet 224 is an integrally formed structure. The liquid inlet 222 and the air outlet 224 are simultaneously formed on the guide portion 22, which can also improve the utilization rate of the guide portion 22 and make the structure of the atomizer 100 more compact.

[0052] The number of the liquid inlet hole 222 and the air outlet hole 224 can be only one, or there can be one liquid inlet hole 222 and multiple air outlet holes 224, or there can be multiple liquid inlet holes 222 and one air outlet hole 224, or there can be multiple liquid inlet holes 222 and multiple air outlet holes 224. In the present application, the number of the liquid inlet hole 222 and the air outlet hole 224 is not specifically limited.

[0053] The cross-sectional shape of the liquid inlet hole 222 is a non-circular hole. Specifically, the cross-sectional shape of the liquid inlet hole 222 can be a regular shape such as an ellipse, rectangle, triangle, etc., or an irregular shape such as a quadrilateral, pentagon, etc., which are not listed here one by one.

[0054] The advantage of setting the shape of the liquid inlet hole 222 to a non-circular hole is that the non-circular hole can prevent the smoke liquid from generating a liquid film when entering the liquid inlet hole 222, thereby ensuring the smoothness of the smoke liquid transmission and avoiding the phenomenon of dry burning or reduced smoke volume during continuous inhalation. The liquid film means that when the smoke liquid flows into the liquid inlet hole 222, a layer of bubble film will be formed at the opening of the liquid inlet hole 222, thereby blocking the liquid inlet hole 222.

[0055] like Figure 6 As shown, the inner surface of the air outlet 224 is configured to include an arc-shaped surface to increase the residence time of the smoke in the air outlet 224, thereby effectively reducing the temperature of the converted smoke and preventing the smoke from being too hot when flowing out of the air outlet 224 and the smoke channel 14, thereby preventing burns.

[0056] like Figure 3 and Figure 5 As shown, in this embodiment, the accommodating portion 26 includes a lower surface 261 and a through hole 263, the lower surface 261 cooperates with the first surface 321 of the atomizer core 30, and the through hole 263 is connected to the liquid inlet hole 222 on the guide portion 22. The number of through holes 263 can be the same as the number of liquid inlet holes 222 on the guide portion 22, that is, a through hole 263 is correspondingly provided on the accommodating portion 26 at the position of each liquid inlet hole 222, so that the liquid inlet hole 222 is connected to the atomizer core 30, so that the smoke liquid can reach the atomizer core 30 through the liquid inlet hole 222. Alternatively, the accommodating portion 26 is only provided with one through hole 263, and each liquid inlet hole 222 is connected to the through hole 263, and the present application does not make any specific restrictions on this.

[0057] The accommodating portion 26 is used to partially accommodate the atomizer core 30. Specifically, in this embodiment, the accommodating portion 26 is connected to the guiding portion 22, the atomizer core 30 is partially accommodated in the accommodating cavity 262 of the accommodating portion 26, and the first surface 321 of the atomizer core 30 abuts against the lower surface 261 of the accommodating portion 26 through the sealing member 28, thereby achieving a sealed fit between the accommodating portion 26 and the atomizer core 30, that is, a sealed fit between the base 20 and the atomizer core 30.

[0058] The base 20 is an integrally formed component, which can reduce the number of components of the atomizer 100 , making installation more convenient and providing better sealing performance.

[0059] In this embodiment, the atomizer core 30 may include a porous matrix 32 and a heating element 34 disposed on the porous matrix 32 , and the heating element 34 is used to atomize the smoke liquid guided through the porous matrix 32 .

[0060] See also Figures 3 to 5 The sealing member 28 is disposed between the base 20 and the porous matrix 32, and is sleeved on the first surface 321 and the side surface 324 of the porous matrix 32. In this embodiment, the sealing member 28 has an upper wall 282 matched with the first surface 321 of the porous matrix 32 and a side wall 284 matched with the side surface 324 of the porous matrix 32, so as to seal the gap between the base 20 and the porous matrix 32, thereby achieving a sealed fit between the base 20 and the atomizer core 30, and preventing the leakage of the smoke liquid in the process of flowing from the base 20 into the porous matrix 32.

[0061] The upper wall 282 of the sealing member 28 is located between the lower surface 261 and the porous matrix 32, and a avoidance hole 286 corresponding to the porous matrix 32 is provided on the upper wall 282, and the avoidance hole 286 is connected to the through hole 263. The side wall 284 of the sealing member 28 is sandwiched between the inner wall of the accommodating cavity 262 and the porous matrix 32. Specifically, the sealing member 28 is sleeved on the porous matrix 32 and sandwiched between the porous matrix 32 and the inner wall of the accommodating cavity 262. The advantage of such a setting is that, on the one hand, the porous matrix 32 can be positioned, and on the other hand, the smoke liquid on one side of the porous matrix 32 can be prevented from leaking from the side surface 324 of the porous matrix 32, thereby causing waste.

[0062] The atomizer core 100 further includes a sealing cover 29 , which is disposed on the guide portion 22 and is located between the guide portion 22 and the inner wall of the liquid storage chamber 12 to seal the gap between the base 20 and the cartridge tube 10 to prevent liquid leakage.

[0063] The sealing cover 29 is provided with a conducting hole 292 at a position corresponding to the liquid inlet hole 222, and a surrounding wall 294 is formed at a position corresponding to the gas outlet hole 224 in the direction of the gas outlet hole 224, sandwiched between the gas outlet hole 224 and the smoke passage 40. The conducting hole 292 connects the liquid storage chamber 12 and the liquid inlet hole 222, and the surrounding wall 294 is sandwiched between the gas outlet hole 224 and the smoke passage 40 to prevent the smoke liquid in the liquid storage chamber 12 from entering the gas outlet hole 224.

[0064] The base 40 is used to cooperate with the base 20 to fix the atomizer core 30 between the base 40 and the base 20, and an atomizer cavity 41 is formed between the base 40 and the atomizer core 30, and the atomizer cavity 41 is connected to the air outlet hole 224. The base 40 includes a base bottom wall 42 and a base side wall 44, and the base side wall 44 is provided with a snap-fit ​​structure for connecting with the base 20, and the base bottom wall 42 is provided with an air inlet hole 46, and the air inlet hole 46 is also connected to the atomizer cavity 41.

[0065] The base 40 and the base 20 may be connected via a snap-fit ​​structure. For example, a hook may be provided on the base 20 and a slot may be provided on the base 40; or a hook may be provided on the base 40 and a slot may be provided on the base 20.

[0066] An air inlet 46 is provided on the bottom wall 42 of the base, and the air inlet 46 is connected to the external fluid, and the external airflow is sent from the air inlet 46 into the atomization cavity 41 between the base 40 and the atomization core 30, and further takes away the smoke atomized by the atomization core 30, and is sent out of the smoke channel 14 through the air outlet 224.

[0067] In this embodiment, six circular air inlet holes 46 arranged in a plum blossom shape are provided on the bottom wall 42 of the base. In other embodiments, at least one air inlet hole 46 is provided on the bottom wall 42 of the base; when a plurality of air inlet holes 46 are provided on the bottom wall 42 of the base, the plurality of air inlet holes 46 can be arranged in other ways, such as in an array or in a star shape, etc., which is not specifically limited here. The shape of the air inlet hole 46 can also be any regular or irregular shape, which is not specifically limited here in this application.

[0068] Furthermore, in this embodiment, the maximum dimension of the cross section of each air inlet hole 46 is less than or equal to 0.2 mm. After many studies and tests, it is found that when the maximum dimension of the hole is less than or equal to 0.2 mm, liquid will not be able to pass through the hole. Therefore, in this embodiment, the maximum dimension of the cross section of the air inlet hole 46 is set to be less than or equal to 0.2 mm, which can further prevent the smoke liquid from leaking out of the air inlet hole 46, thereby affecting the use.

[0069] Combined with reference Figures 3 to 5In this embodiment, the atomizer core 30 may include a porous substrate 32 and a heating element 34 disposed on the porous substrate 32, and the heating element 34 is used to atomize the smoke liquid guided through the porous substrate 32. Specifically, the heating element 34 may be at least one of a heating coating, a heating circuit, a heating sheet, or a heating net, and the heating element 34 is electrically connected to the power supply assembly 200 through the electrode 34.

[0070] The porous matrix 32 may be porous glass or porous ceramics, etc. In this embodiment, the porous matrix 32 is porous ceramics. Porous ceramic materials are generally ceramic materials sintered at high temperatures by components such as aggregates, binders, and pore-forming agents, and have a large number of pore structures that are interconnected with each other and with the surface of the material. Since porous ceramic materials have excellent properties such as high porosity, stable chemical properties, large specific surface area, low volume density, low thermal conductivity, and high temperature and corrosion resistance, they have many applications in metallurgy, biology, energy, environmental protection and other fields.

[0071] In this embodiment, a porous ceramic material is selected to make the porous matrix 32. The smoke liquid on one side of the porous matrix 32 penetrates to the other side of the porous matrix 32 through a large number of pore structures inside the porous ceramic material that are connected to each other and to the surface of the material, and contacts with the heating element 34 arranged on one side of the porous matrix 32, thereby atomizing the smoke liquid into smoke.

[0072] Combined with reference Figure 7 , Figure 7 for Figure 2 A schematic diagram of a first cross-sectional structure of a porous matrix in the atomizer is shown.

[0073] Specifically, the porous matrix 32 has a first surface 321, a second surface 322 and a side surface 324, the second surface 322 is arranged opposite to the first surface 321, and the side surface 324 connects the first surface 321 and the second surface 322. Generally speaking, the first surface 321 can be used to contact the smoke liquid communicated with the liquid storage chamber 12, and the second surface 322 can be used to contact with gas, and the gas contact mentioned here can be the second surface 322 contacting with the external air, contacting with the air in the atomization chamber 41, or contacting with the air in the smoke channel 14, etc.

[0074] In this embodiment, the smoke liquid on the first surface 321 of the porous matrix 32 penetrates to the second surface 322 of the porous matrix 32 through a large number of pore structures inside the porous matrix 32 that are connected to each other and to the material surface, and the heating element 34 is arranged on the second surface 322 to atomize the smoke liquid that penetrates to the second surface 322. The side surface 324 is also connected with the pore structure, so the side surface 324 can also be used for liquid conduction or ventilation.

[0075] The porous matrix 32 includes a connected liquid guide portion 323 and a ventilation portion 325, wherein the liquid guide portion 323 has a liquid absorption surface 326 for absorbing liquid matrix and an atomization surface 327 provided with a heating element 34, and the liquid guide portion 323 is used to conduct the liquid matrix located on one side of the liquid absorption surface 326 to the atomization surface 327, and the ventilation portion 325 has a liquid-repellent and air-permeable property, wherein the liquid-repellent property is for the liquid matrix to be atomized, and as long as the liquid matrix to be atomized has the liquid-repellent property, it is the liquid-repellent property mentioned here, and the air-permeable property is achieved due to the large number of pore structures interconnected with each other inside the porous matrix 32 being air-permeable. The ventilation portion 325 is used to conduct gas into the liquid storage chamber 12 to improve the air pressure condition in the liquid storage chamber 12.

[0076] Specifically, the ventilation part 325 includes an air inlet surface 328 and an air outlet surface 329, the air inlet surface 328 can be used to contact with gas, and the air outlet surface 329 is used to be exposed to the liquid storage chamber 12, wherein the exposure to the liquid storage chamber 12 includes the air outlet surface 329 directly being a wall surface of the liquid storage chamber 12 or the air outlet surface 329 being in liquid-conducting communication with the liquid storage chamber 12, and the gas contact mentioned here can be the air inlet surface 328 contacting with external air, the air inlet surface 328 contacting with air in the atomization chamber 41, or the air inlet surface 328 contacting with air in the smoke passage 14, etc. The ventilation part 325 can be used to conduct the gas on one side of the air inlet surface 328 to the air outlet surface 329, where the gas is generally mainly air, and finally conduct the gas to the liquid storage chamber 12.

[0077] In this embodiment, the liquid guiding portion 323 is used to guide the smoke liquid from the first surface 321 to the second surface 322 , and the ventilation portion 325 is used to guide the gas from the second surface 322 to the first surface 321 .

[0078] In this embodiment, the porous matrix 32 is an integrally formed component. A portion of the porous matrix 32 is treated with ceramic modification technology to obtain liquid-repellent properties, the unmodified matrix serves as the liquid-conducting portion 323, the pore structure in the liquid-conducting portion 323 is used to conduct the smoke liquid, and the modified portion of the matrix serves as the ventilation portion 325, and the ventilation portion 325 does not have the function of conducting the smoke liquid but only performs gas exchange.

[0079] Among them, the ceramic modification technology can be micro-nano technology, physical vapor deposition, etching, electroplating, spraying or plasma technology, etc. For example, micro-nano technology is used to change the pore structure of part of the substrate so that the smoke liquid does not enter the pore structure in the ventilation part 325 without affecting the air permeability of the pore structure, so that the ventilation part 325 has liquid-repellent and air-permeable properties. Alternatively, physical vapor deposition, electroplating or spraying of hydrophobic material to part of the substrate of the porous substrate 32 is used, and the hydrophobic material can be olefin polymers, amine polymers, ester polymers, fluorine-containing resins, siloxane compounds, silane compounds or thiol compounds, etc., and then heat-treated to form a ventilation part 325 with hydrophobic and air-permeable properties.

[0080] In other embodiments, the porous matrix 32 may also be a non-integrated component, and the liquid guiding portion 323 and the ventilation portion 325 may be detachably connected, for example, the ventilation portion 325 and the liquid guiding portion 323 may be snapped, embedded, or screwed, etc., and the present application does not make any specific limitation on this.

[0081] The porous matrix 32 can be in a flat or stepped shape, etc., and the present application does not impose any specific restrictions on this. The first surface 321 is the surface of the porous matrix 32 facing the liquid storage chamber 12, and the second surface 322 is the surface of the porous matrix 32 facing away from the first surface 321. The first surface 321 and the second surface 322 can both be flat planes, and the first surface 321 and the second surface 322 can also be irregular surfaces such as curved surfaces, and the present application does not impose any specific restrictions on this. For example, a groove is provided on one side of the first surface 321 of the porous matrix 32, and the surface of the groove also belongs to the first surface 321.

[0082] The number of ventilation parts 325 is at least one, and multiple ventilation parts 325 can be set on the porous matrix 32, for example, three or four ventilation parts 325 of equal number are arranged on each side along the circumference of the porous matrix 32, and the present application does not make any specific limitation on this.

[0083] Combined with reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the first surface 321 is the surface of the porous substrate 32 facing the liquid storage chamber 12. The smoke liquid in the liquid storage chamber 12 passes through the conducting hole 292, the liquid inlet hole 222, the through hole 263 and the avoidance hole 286 to the first surface 321 of the porous substrate 32. The smoke liquid then penetrates through the first surface 321 to the second surface 322. The heating element 34 disposed on the second surface 322 atomizes the penetrated smoke liquid to form smoke in the atomization chamber 41. The smoke flows through the side surface of the guide portion 22 and the air outlet hole 224 in sequence, and flows into the smoke channel 14 and flows out, and is guided to the user's mouth through the smoke channel 14. The second surface 322 is the surface of the porous substrate 32 away from the liquid storage chamber 12, and the air inlet hole 46 on the bottom wall 42 of the base is connected with the external fluid, and the external airflow is sent from the air inlet hole 46 to the atomization chamber 41, that is, the airflow will take away the smoke generated by atomization at the second surface 322.

[0084] The liquid in the liquid storage chamber 12 is consumed continuously as the user draws, and the liquid in the liquid storage chamber 12 is reduced, which in turn causes the air pressure in the liquid storage chamber 12 to decrease. If not improved in time, the liquid in the liquid storage chamber 12 may not flow smoothly through the porous matrix 32, and the heating element 34 may dry burn and produce a burning smell due to the poor liquid supply. Due to the presence of the ventilation part 325, when the pressure difference between the inside and outside of the liquid storage chamber 12 is too large, air can be introduced from one side of the second surface 322 through the ventilation part 325 to the first surface 321 to improve the low pressure condition in the liquid storage chamber 12, avoid the excessive pressure difference between the inside and outside of the liquid storage chamber 12, and facilitate the liquid in the liquid storage chamber 12 to flow smoothly and avoid the burning smell.

[0085] For example Figures 7 to 9 As shown, the ventilation portion 325 penetrates the porous matrix 32 in the direction from the first surface 321 to the second surface 322. Due to the liquid-repellent and air-permeable characteristics of the ventilation portion 325, the gas can be introduced from one side of the second surface 322 to one side of the first surface 321 along the pore structure in the ventilation portion 325, so as to improve the air pressure condition in the liquid storage cavity 12 and avoid excessive air pressure difference between the inside and outside of the liquid storage cavity 12. The arrows in the drawings are used to indicate the direction of the gas.

[0086] Specifically, in the first embodiment, see Figures 7 to 9 In the porous matrix 32, the liquid absorption surface 326 and the gas outlet surface 329 are both located on the first surface 321, and the gas inlet surface 328 and the atomization surface 327 are both located on the second surface 322. In other words, the ventilation portion 325 has a portion of the first surface 321 and a portion of the second surface 322, so the portion of the porous matrix 32 located between the gas outlet surface 329 and the gas inlet surface 328 will not have the function of conducting the smoke liquid, but will transport the gas entering through the gas inlet surface 328 to the gas outlet surface 329 under the action of the pressure difference, so as to adjust the gas pressure in the liquid storage chamber 12.

[0087] In addition, if part of the side surface 324 is exposed to the smoke liquid connected to the liquid storage chamber 12 , the side surface 324 can also serve as a liquid absorption surface 326 , and if the ventilation portion 325 has part of the side surface 324 , the part of the side surface 324 can also serve as a gas outlet surface 329 .

[0088] like Figures 7 to 9 As shown, the ventilation portion 325 extends from the air outlet surface 329 to the air inlet surface 328. In other words, the ventilation portion 325 penetrates the porous matrix 32 along the direction from the first surface 321 to the second surface 322. The ventilation portion 325 can be used to directly conduct the gas on one side of the second surface 322 to the side of the first surface 321 to improve the air pressure condition in the liquid storage chamber 12.

[0089] Combined with reference Figure 5 , Figure 7 and Fig.15 , Figure 7 and Fig.15 They are Figure 2 Another porous substrate 32 in the atomizer is shown in cross-sectional and top view. The porous substrate 32 is used to replace Figure 5 The porous matrix 32 in FIG.

[0090] Specifically, the ventilation portion 325 is located in the middle of the porous matrix 32, and the ventilation portion 325 is spaced apart from the side surface 324 of the porous matrix 32, wherein the first surface 321 faces the liquid storage chamber 12, and the second surface 322 faces the atomization chamber 41, and the liquid guiding portion 323 seals the surrounding side of the ventilation portion 325 with liquid, and the ventilation portion 325 takes in air from the air inlet surface 328 located on the second surface 322, and conducts the gas to the air outlet surface 329 located on the first surface 321, thereby introducing the gas outside the liquid storage chamber 12 into the liquid storage chamber 12 to adjust the air pressure conditions in the liquid storage chamber 12.

[0091] Combined with reference Figure 5 , Figure 7 and Fig.16 , Fig.16 for Figure 7 Another schematic diagram of the top view of the porous matrix. The ventilation portion 325 is located in the middle of the porous matrix 32, and the ventilation portion 325 also has a partial side surface 324, wherein the first surface 321 faces the liquid storage chamber 12, and the second surface 322 faces the atomization chamber 41. The side surface 324 of the porous matrix 32 is sealed by the side wall 284 of the seal 28, and the ventilation portion 325 can directly introduce the gas in the atomization chamber 41 on the side of the second surface 322 into the liquid storage chamber 12 on the side of the first surface 321. In other embodiments, if at least part of the side surface 324 is exposed to the gas in the atomization chamber 41, the ventilation portion 325 can also take in air from the side surface 324; if at least part of the side surface 324 is exposed to the smoke liquid connected to the liquid storage chamber 12, the ventilation portion 325 can also discharge air from the side surface 324, and the liquid guide portion 323 can also absorb liquid from the side surface 324.

[0092] Combined with reference Figure 5 , Figure 8 and Fig.17 , Fig.17 for Figure 8A schematic diagram of a top view of the porous matrix. The ventilation portion 325 is located at the edge of the porous matrix 32, that is, the ventilation portion 325 is located outside the liquid guide portion 323, and the ventilation portion 325 also has a partial side surface 324, and the side surface 324 is sealed by the side wall 284, so that the ventilation portion 325 can directly introduce the gas in the atomization chamber 41 into the liquid storage chamber 12. In other embodiments, if at least a portion of the side surface 324 is exposed to the gas in the atomization chamber 41, the ventilation portion 325 can also take in air from the side surface 324; if at least a portion of the side surface 324 is exposed to the smoke liquid connected to the liquid storage chamber 12, the ventilation portion 325 can also discharge air from the side surface 324, and the liquid guide portion 323 can also absorb liquid from the side surface 324.

[0093] Combined with reference Figure 5 , Fig. 9 and Fig.18 , Fig.18 for Fig. 9 A schematic diagram of a top view of the structure of the porous matrix. The ventilation portion 325 is annular and arranged around the outer side of the liquid guide portion 323. In other words, the ventilation portion 325 is arranged in a ring shape along the edge of the porous matrix 32. The ventilation portion 325 can directly introduce the gas in the atomization chamber 41 into the liquid storage chamber 12, so that the ventilation portion 325 can ventilate more evenly, and due to the liquid-repellent characteristics of the ventilation portion 325, it can also lock the porous matrix 32 and prevent the liquid in the liquid guide portion 323 from leaking from the side surface 324; a side wall 284 sealed with a seal 28 is sandwiched between the side surface 324 of the porous matrix 32 and the inner wall of the accommodating chamber 262, and the ventilation portion 325 cooperates with the side wall 284 to further improve the sealing effect. In other embodiments, if part of the side surface 324 is exposed to the gas in the atomization chamber 41, the ventilation portion 325 can also take in air from the side surface 324; if part of the side surface 324 is exposed to the smoke liquid connected to the liquid storage chamber 12, the ventilation portion 325 can also discharge air from the side surface 324, and the liquid guiding portion 323 can also absorb liquid from the side surface 324.

[0094] Combined with reference Figure 5 , Fig. 9 and Fig.19 , Fig.19 for Fig. 9 Another schematic diagram of the top view of the porous matrix. A plurality of ventilation portions 325 are arranged at intervals along the outer side surface of the liquid guide portion 323. In other words, a plurality of ventilation portions 325 are arranged around the side surface 324 of the porous matrix 32, so that a uniform ventilation effect can be achieved, and a local area of ​​the porous matrix 32 has a liquid locking effect, and the local sealing effect of the porous matrix 32 is further improved.

[0095] In the second embodiment, see Fig.10The liquid absorption surface 326 and the gas outlet surface 329 are both located on the first surface 321 , the gas inlet surface 328 is located on the side surface 324 , and the atomization surface 327 is located on the second surface 322 .

The ventilation part 325 takes in air from the side surface 324, so that air can be taken in from the inlet surface 328 and discharged from the outlet surface 329 to the liquid storage chamber 12 under the action of the pressure difference, so as to adjust the air pressure condition in the liquid storage chamber 12.

[0097] Therefore, the ventilation portion 325 may not penetrate the porous substrate 32, so as to shorten the time required to manufacture the ventilation portion 325 and reduce the manufacturing cost. In other embodiments, if at least a portion of the side surface 324 is also exposed to the smoke liquid connected to the liquid storage chamber 12, the ventilation portion 325 may also discharge air from the air inlet surface 328, and the liquid guide portion 323 may also absorb liquid from the side surface 324.

Under the action of the pressure difference, the ventilation part 325 takes in air from the air inlet surface 328 and conducts the gas to the air outlet surface 329, and at least part of the air outlet surface 329 is exposed to the smoke liquid connected to the liquid storage chamber 12, so that the ventilation part 325 can introduce the gas into the liquid storage chamber 12.

[0100] In another embodiment, see Fig.13 The ventilation part 325 is a protrusion disposed on the side surface 324. It can also be considered that the air inlet surface 328 and the air outlet surface 329 are both located on the side surface 324, and the ventilation part 325 can inlet air from the air inlet surface 328 facing the atomization chamber 41, and guide the gas to the liquid storage chamber 12 from the air outlet surface 328 facing the liquid storage chamber 12. The ventilation part 325 can be disposed on the upper edge of the side surface 324 close to the first surface 321, or the ventilation part 325 is disposed on the lower edge of the side surface 324 close to the second surface 322, or the ventilation part 325 is disposed in the middle of the side surface 324. The ventilation part 325 can be disposed in an annular shape along the side surface 324, or a plurality of ventilation parts can be disposed at intervals along the circumference of the side surface 324.

[0101] In the fifth embodiment, in conjunction with reference to Fig.14 and Fig.15 , Fig.15 for Fig.14 The air inlet surface 328 and the air outlet surface 329 are both located on the first surface 321 , the liquid absorption surface 326 is located on the first surface 321 and / or the side surface 324 , the ventilation portion 325 is spaced apart from the second surface 322 , and the atomization surface 327 is located on the second surface 322 .

[0103] Among them, if the first surface 321 is exposed to the smoke liquid connected to the liquid storage chamber 12, the liquid absorption surface 326 is located on the first surface 321; if the first surface 321 and a portion of the side surface 324 are exposed to the smoke liquid connected to the liquid storage chamber 12, the liquid absorption surface 326 is located on the first surface 321 and the side surface 324; if the air outlet surface 329 is exposed to the smoke liquid connected to the liquid storage chamber 12, and the rest of the first surface 321 is not exposed to the smoke liquid connected to the liquid storage chamber 12, and a portion of the side surface 324 is exposed to the smoke liquid connected to the liquid storage chamber 12, then the liquid absorption surface 326 is located on the side surface 324.

[0104] In the sixth embodiment, see Fig. 20The porous matrix 32 is stepped, the liquid guide portion 323 includes a body 3231 and a protrusion 3232 of an integral structure, the body 3231 is provided with a groove 3233, the side of the protrusion 3232 away from the groove 3233 is used to set the heating element 34, and the ventilation portion 325 is arranged on the outer side of the body 3231 to form the outer edge of the porous matrix 32. The porous matrix 32 includes two outer edges arranged on two opposite sides of the body 3231, one of the outer edges can be set as the ventilation portion 325 through the ceramic modification technology, or the two outer edges are set as the ventilation portion 325 through the ceramic modification technology, or the outer edges of the entire circumference of the body 3231 can also be set as the ventilation portion 325 through the ceramic modification technology.

[0105] The surface of the body 3231 and the outer edge facing the liquid storage chamber 12 is the first surface 321 , the first surface 321 also includes the surface of the groove 3233 , and the surface of the body 3231 and the outer edge away from the first surface 321 is the second surface 322 .

[0106] In other words, the first surface 321 of the porous matrix 32 is provided with a groove 3233. After the smoke liquid in the liquid storage chamber 12 enters the groove 3233, the contact area between the smoke liquid and the porous matrix 32 can be increased, thereby improving the diffusion speed of the smoke liquid; and the groove 3233 can also reduce the distance between the first surface 321 and the second surface 322 of the porous matrix 32, thereby reducing the flow resistance of the smoke liquid to the second surface 322 of the porous matrix 32, further improving the diffusion speed of the smoke liquid, thereby effectively improving the liquid conduction efficiency of the porous matrix 32.

[0107] See also Fig.21 In this embodiment, a magnet 210 is provided between the power assembly 200 and the atomizer 100, and the two ends of the magnet 210 attract the power assembly 200 and the atomizer 100 respectively, thereby connecting the power assembly 200 and the atomizer 100. That is, in this embodiment, the power assembly 200 and the atomizer 100 are connected by a magnetic attraction structure.

[0108] For further information, please refer to Fig.18The electronic atomization device 300 in this embodiment further includes an airflow controller 230, which is arranged on the passage connecting the air inlet 46 with the outside world, and is used to open the gas passage of the electronic atomization device 300 under the action of the suction force generated by sucking the electronic atomization device 300, and close the gas passage of the electronic atomization device 300 when there is no suction force. Specifically, when the airflow controller 230 detects the suction force of the electronic atomization device 300, the airflow controller 230 opens the gas passage, so that the airflow enters the atomizer 100 from the air inlet 46, and the flowing airflow drives the generated smoke to flow out from the smoke channel 14 for the user to inhale. When the airflow controller 230 does not detect the suction force of the electronic atomization device 300, the airflow controller 230 closes the gas passage, thereby preventing the smoke from flowing out of the smoke channel 14, which plays a role in saving smoke liquid.

[0109] Different from the prior art, the present application discloses an atomizer core, an atomizer and an electronic atomization device. The porous matrix of the atomizer core is defined to include a liquid guide portion and a ventilation portion, wherein the ventilation portion has liquid-repellent and air-permeable properties, so that when the liquid guide portion guides the liquid in the liquid storage cavity from the liquid suction surface to the atomization surface, the external gas can also be guided to the liquid storage cavity through the ventilation portion, thereby solving the problem of poor liquid flow caused by too low air pressure in the liquid storage cavity due to the liquid guide of the atomizer core, so as to facilitate the recovery of air pressure in the liquid storage cavity and enable the liquid to be smoothly guided from the liquid suction surface to the atomization surface. Therefore, the atomizer core provided by the present application can supply air to the liquid storage cavity on the side of the liquid suction surface, improve the air pressure condition in the liquid storage cavity, and avoid the situation of poor liquid flow caused by too low air pressure in the liquid storage cavity.
