[0069] Please also read Figure 1 and Figure 3 The present application provides an atomization device 1, which includes a housing 10, an oil supply assembly 20, an atomization assembly 30, a sensing assembly 90 and a power supply assembly 110. The housing 10 is not only used to side-mount the oil supply assembly 20, but also used to accommodate the atomization assembly 30, the sensing assembly 90 and the power supply assembly 110. The sensing assembly 90 is used to sense the change of air pressure in the housing 10 to open and close the power supply assembly 110. The power supply assembly 110 is connected to the atomization assembly 30 and used to supply power to the atomization assembly 30. The oil supply assembly 20 is used to provide the atomization assembly 30 with a liquid aerosol-generating matrix of floral, herbal and synthetic types. The atomization assembly 30 is used to heat and atomize the aerosol-generating matrix to form an aerosol for the user to inhale.

[0070] Please refer again Figure 1 , Figure 2 , Figure 3 The housing 10 has an air inlet 17, a power supply cavity 16, a mounting cavity 15, an atomizing cavity 11, an air outlet channel 13 and an oil guide channel 12. The air inlet 17 is located at the bottom end of the housing 10, and the air outlet channel 13 is located at the top end of the housing 10. In the extension direction of the atomizing cavity 11 (such as Figure 3 On the upper side (indicated by the middle arrow E), the air inlet 17, the power supply cavity 16, the installation cavity 15, the atomization cavity 11 and the air outlet channel 13 are connected in sequence, and the oil guide channel 12 is arranged on one side of the atomization cavity 11 and is connected to the atomization cavity 11.

[0071] Specifically, the extension direction of the atomizing chamber 11 is not parallel to the extension direction of the oil guiding channel 12. Preferably, the extension direction of the atomizing chamber 11 is perpendicular to the extension direction of the oil guiding channel 12. Figure 3 , Figure 7 , Fig.11 , Fig.13 , Fig.14 and Fig.15The atomization assembly 30 is arranged in the atomization chamber 11, and includes a bracket 31, an oil-conducting cotton 32, a heating element and a central tube 33. The bracket 31 and the central tube 33 are both hollow structures with openings at both ends, and both extend in the same direction as the atomization chamber 11. An oil-conducting hole 311 is provided on the side wall of the bracket 31. The central tube 33 and the oil-conducting cotton 32 are both located in the bracket 31, and the central tube 33 has a central channel 331 and a through hole 332 connected to the central channel 331. The oil-conducting cotton 32 is arranged around the circumference of the central tube 33 and covers the oil-conducting hole 311 and the through hole 332 at the same time. The central channel 331 is connected to the air outlet channel 13, and the heating element is located in the central channel 331.

[0072] Please refer again Figure 1 and Figure 3 , and also see Fig.19 The oil supply assembly 20 is at least partially located outside the housing 10 and is detachably mounted on one side of the atomizing chamber 11. The oil supply assembly 20 includes an oil supply body 21. The oil supply body 21 has an oil supply chamber 215 and an oil outlet hole 211 disposed on one side of the oil supply chamber 215. The oil guide channel 12 is inserted into the oil outlet hole 211 and communicates between the oil supply chamber 215 and the atomizing chamber 11.

[0073] The extension direction of the atomizing chamber 11 is perpendicular to the extension direction of the oil guide channel 12, so as to facilitate the side mounting of the oil supply assembly 20 and the housing 10. Figure 3 , Figure 6 , Figure 7 and Figure 8 The sensing component 90 is arranged in the power supply cavity 16, and the sensing component 90 includes a mounting seat 91 and a microphone 92. The mounting seat 91 is provided with a mounting groove 911, a sensing airway 912 and an air passage 913. The sensing airway 912 is connected between the mounting groove 911 and the central channel 331, and the air passage 913 is also connected to the central channel 331. The microphone 92 is assembled in the mounting groove 911.

[0074] The power supply component 110 is disposed in the power supply cavity 16 and is electrically connected to the heating element. The power supply component 110 is a conventional design in the art, so the specific structure of the power supply component 110 is not described in detail here.

[0075] See also Figure 3 , Figure 6 , Figure 7 , Fig.11 , Fig.13 , Fig.14 and Fig.15 As shown, the aerosol-generating matrix in the oil supply chamber 215 passes through the oil guide channel 12, the atomizing chamber 11 and the oil guide hole 311 in sequence, and is adsorbed on the oil guide cotton 32 (the flow path of the aerosol-generating matrix is ​​shown in FIG. Figure 3During suction, the air in the mounting groove 911 is discharged through the induction air passage 912, the central passage 331 and the air outlet passage 13 in sequence (the air flow path is shown in FIG. Figure 6 As shown in b→c→e→f in the figure), negative pressure is formed in the installation groove 911, the microphone 92 senses the existence of negative pressure, the power supply component 110 starts, and supplies power to the heating element. The heating element transfers heat to the oil-conducting cotton 32 through the tube wall of the central tube 33 to atomize the aerosol-generating matrix on the oil-conducting cotton 32 to form an aerosol, and then the aerosol enters the central tube 33 through the through hole 332 on the central tube 33. At the same time, in the process of continuous suction, external air enters the central channel 331 through the air inlet 17, the power supply cavity 16 and the air passage 913, so that the aerosol in the central channel 331 can be mixed with the air, and finally diffused to the outside through the air outlet channel 13 and inhaled by the user.

[0076] In the present application, by at least partially disposing the oil supply assembly 20 outside the outer shell 10, and the oil supply assembly 20 is detachably installed on one side of the atomization chamber 11, on the one hand, it is convenient to side-mount the oil supply assembly 20 and the outer shell 10, thereby improving the assembly efficiency of the atomization device 1; on the other hand, the oil supply assembly 20 and / or components in the outer shell 10 can be reused by disassembly, thereby saving resources and reducing the cost of use.

[0077] For example, when the heating element is burned out due to overheating, but a large amount of aerosol generating substrate is still stored in the oil supply cavity 215 of the oil supply assembly 20, the housing 10 and the oil supply assembly 20 can be disassembled, and the oil supply assembly 20 can be assembled to another housing 10 for reuse. For another example, when the oil supply body 21 of the oil supply assembly 20 ages and cracks, resulting in oil leakage, the housing 10 and the oil supply assembly 20 can also be disassembled, and a new oil supply assembly 20 can be replaced and installed on the housing 10, so as to realize the reuse of the housing 10 and the components inside the housing 10.

[0078] See also Figures 4 to 6 , Figures 18 to 20 In some optional embodiments, the housing 10 includes an oil guide tube 18, which protrudes from one side of the atomizing chamber 11 and is configured to form an oil guide channel 12, and the oil guide tube 18 is detachably inserted into the oil outlet hole 211. The oil supply assembly 20 also includes an elastic seal 22, which is disposed in the oil outlet hole 211 and seals the gap between the hole wall of the oil outlet hole 211 and the outer side wall of the oil guide tube 18.

[0079] Specifically, the elastic sealing member 22 may be rubber, silicone or other elastic components.

[0080] On the one hand, the elastic seal 22 can seal the gap between the outer wall of the oil guide tube 18 and the hole wall of the oil outlet hole 211, ensuring that the aerosol-generating substrate in the oil supply chamber 215 can only be introduced into the atomizing chamber 11 from the oil guide channel 12, thereby reducing the risk of oil leakage from the oil supply assembly 20. On the other hand, the elastic seal 22 can facilitate the detachable side mounting of the oil guide tube 18 and the oil supply assembly 20.

[0081] Furthermore, the atomizer 1 has a disassembled state and an installed state. When the atomizer 1 is in the disassembled state, the oil supply assembly 20 and the housing 10 are disassembled, and the elastic seal 22 is retracted and tends to close the oil outlet 211. When the atomizer 1 is in the installed state, the elastic seal 22 is torn by the force of the oil guide tube 18 and allows the oil guide tube 18 to be detachably inserted into the oil outlet 211, and the elastic seal 22 seals the gap between the hole wall of the oil outlet 211 and the outer wall of the oil guide tube 18, and the oil guide channel 12 is connected between the oil supply chamber 215 and the atomizer chamber 11.

[0082] By using the elastic seal 22, the oil guide pipe 18 and the oil supply assembly 20 can be detachably mounted on the side, so as to facilitate the assembly of the oil supply assembly 20 and the housing 10. In the specific disassembly and assembly process, after the elastic seal 22 is pressed and torn by the oil guide pipe 18, the elastic seal 22 can rely on its own elastic force to pull back the outer wall of the oil guide pipe 18 and seal on the outer wall of the oil guide pipe 18, so as to realize the side mounting of the oil supply assembly 20 and the housing 10, and make the aerosol generating matrix in the oil supply chamber 215 only flow from the oil guide channel 12 inside the oil guide pipe 18 to the atomizing chamber 11, and cannot flow outward along the outer wall of the oil guide pipe 18, thereby reducing the risk of oil leakage. When disassembling, the oil supply assembly 20 is directly operated to move back to the housing 10, so that the oil guide pipe 18 can withdraw from the oil outlet hole 211, so as to realize the disassembly between the oil supply assembly 20 and the housing 10. When the oil guide pipe 18 withdraws from the oil outlet hole 211, the elastic seal 22 retracts and approaches closing. That is, when the oil supply assembly 20 is removed from the housing 10, the remaining aerosol generating matrix in the oil supply chamber 215 is difficult to leak from the nearly closed crack, thereby improving the reliability of disassembly and assembly of the oil supply assembly 20.

[0083] See also Figure 5 and Fig.19 Furthermore, in some optional embodiments, the elastic seal 22 includes a mounting portion 221 and a weak portion 222. The mounting portion 221 is a hollow cylindrical structure with openings at both ends. The mounting portion 221 is installed in the oil outlet hole 211 and has an interference fit with the oil outlet hole 211. The weak portion 222 is arranged in the mounting portion 221 and is used to be torn with the help of the force of the oil guide pipe 18.

[0084] The weak portion 222 refers to a portion whose structure is relatively weak and is easy to be broken, pierced, or torn. For example, the weak portion 222 is a portion of the elastic seal 22 that is thinner in the extending direction of the central axis of the oil outlet hole 211 .

[0085] By configuring the elastic sealing member 22 to include the mounting portion 221 and the weak portion 222 , the oil guide tube 18 can be operated to pierce and tear the weak portion 222 with less effort, which saves effort and is convenient to operate.

[0086] In some optional embodiments, the mounting portion 221 and the weak portion 222 are integrally formed. This method is convenient for forming and helps to reduce the manufacturing cost of the atomization device 1 .

[0087] Of course, in some other optional embodiments, the mounting portion 221 and the weak portion 222 can also be formed separately and connected by adhesives, fasteners or other connecting parts. In this embodiment, the mounting portion 221 and the weak portion 222 can be made of the same or different materials.

[0088] Further, in some optional embodiments, the hole wall of the oil outlet hole 211 protrudes to form an annular positioning boss 212, and the elastic seal 22 abuts against the positioning boss 212. During the actual installation process, the elastic seal 22 is pressed into the oil outlet hole 211 so that an interference fit is formed between the elastic seal 22 and the oil outlet hole 211. During the pressing process, if the pressure is too large, the elastic seal 22 is easily pressed into the oil supply chamber 215, causing the sealing function of the elastic seal 22 to fail. In the present application, by designing the positioning boss 212, the positioning boss 212 can prevent the elastic seal 22 from entering the oil supply chamber 215, and can position the elastic seal 22 to facilitate the installation of the elastic seal 22.

[0089] See also Figure 3 and Figure 5 , Figures 17 to 19 In some optional embodiments, the oil supply assembly 20 further includes a sealing film 23, which is disposed on the oil supply body 21 and is located on the side of the elastic seal 22 facing away from the oil supply cavity 215. The sealing film 23 is configured to seal the oil outlet hole 211 before the oil guide tube 18 is inserted into the oil outlet hole 211 for the first time, and the sealing film 23 is punctured by the force of the oil guide tube 18.

[0090] The sealing film 23 may be an aluminum foil film, a plastic film, or the like.

[0091] Specifically, after the atomizer 1 leaves the factory and before the oil guide tube 18 is inserted into the oil outlet hole 211 for the first time, the atomizer 1 is in a disassembled state. During this process, the sealing film 23 always seals the oil outlet hole 211 and is located on the side of the elastic seal 22 facing away from the oil supply chamber 215. During the transportation of the atomizer 1, the sealing film 23 can prevent the elastic seal 22 from falling out of the oil outlet hole 211, which is not only conducive to improving the reliability of the installation of the elastic seal 22, but also can cooperate with the elastic seal 22 to seal the oil outlet hole 211, and has a better sealing effect, thereby preventing oil leakage from the oil outlet hole 211.

[0092] The oil guide tube 18 is inserted into the oil outlet hole 211 for the first time, so that when the atomizer 1 is switched to the installation state for the first time, the oil guide tube 18 pierces the sealing film 23 and is inserted into the oil outlet hole 211 to realize the oil supply of the oil supply assembly 20. Since the sealing film 23 cannot be automatically closed after being punctured, from then on, whether the atomizer 1 is in the installation state or the disassembly state, the sealing film 23 always maintains the punctured state, and the sealing of the sealing film 23 fails. However, it is worth mentioning that although the sealing film 23 is punctured, the sealing film 23 still has the function of blocking the elastic seal 22, so that the stability and reliability of the installation of the elastic seal 22 can be maintained.

[0093] See also Figure 3 and Fig.19 In some optional embodiments, there are multiple oil guide channels 12 and oil outlet holes 211, all of which are arranged at intervals along the extension direction of the atomization chamber 11, and the oil guide channels 12 correspond to the oil outlet holes 211 one by one, and each oil guide channel 12, the atomization chamber 11 and the oil guide hole 311 are connected in sequence.

[0094] As the accumulated atomization time in the atomizing device 1 increases, the liquid level of the aerosol generating substrate in the oil supply chamber 215 continues to decrease. The extension direction of the atomizing chamber 11 is consistent with the direction of change of the liquid level of the aerosol generating substrate in the oil supply chamber 215. The liquid level of the oil supply body 21 can change in an upward or downward direction. During use, due to the loss of the aerosol generating substrate, the liquid level gradually decreases. When the aerosol generating substrate is insufficiently supplied, the aerosol generating substrate can be added to the oil supply chamber 215. During this process, the liquid level gradually rises.

[0095] Since there are multiple oil outlet holes 211, when the liquid level of the aerosol generating substrate in the oil supply chamber 215 decreases, the aerosol generating substrate can be introduced into the atomizing chamber 11 through the oil outlet holes 211 located below the liquid level and the oil guide channel 12 corresponding to the oil outlet holes 211 located below the liquid level. The provision of multiple oil outlet holes 211 and the oil guide channel 12 increases the oil guide speed.

[0096] In addition, each oil guide channel 12, atomizing chamber 11 and oil guide hole 311 are connected in sequence. Therefore, the aerosol-generating matrix introduced from the oil guide channel 12 into the atomizing chamber 11 can be invaded by the oil guide hole 311 and adsorbed by the oil guide cotton 32 of the atomizing assembly 30. Of course, in some other embodiments, the oil guide channel 12 and the oil outlet hole 211 can also be set as one, the oil outlet hole 211 is set at the bottom end of the oil supply chamber 215, and the oil guide channel 12 is connected with the bottom end of the atomizing chamber 11, so that the aerosol-generating matrix in the oil supply chamber 215 can be introduced into the atomizing chamber 11 as much as possible through the oil outlet hole 211 and the oil guide channel 12.

[0097] See also Figure 3 , Figure 6 , Figure 7 , Figures 9 to 12 In some embodiments of the present application, the air outlet channel 13 is arranged above the atomizing chamber 11 in the extension direction of the atomizing chamber 11, and the atomizing device 1 also includes a first oil-absorbing cotton 40, a first sealing seat 60 and a second sealing seat 70. The first oil-absorbing cotton 40, the first sealing seat 60 and the second sealing seat 70 are all arranged in the atomizing chamber 11, the first oil-absorbing cotton 40 is located above the oil guide hole 311, the first sealing seat 60 is located above the first oil-absorbing cotton 40, and the second sealing seat 70 is located below the oil guide hole 311. The first oil-absorbing cotton 40, the first sealing seat 60 and the second sealing seat 70 are all arranged around the circumference of the bracket 31, and the first sealing seat 60 and the second sealing seat 70 are both used to seal the gap between the bracket 31 and the cavity wall of the atomizing cavity 11. The circumferential side surface of the first oil-absorbing cotton 40 extends along at least a portion of its circumferential arrangement and defines a first cavity 11a with the cavity wall of the atomizing cavity 11. The top surface of the second sealing seat 70 and the bottom surface of the first oil-absorbing cotton 40 define a second cavity 11b. The oil guide channel 12, the first cavity 11a, the second cavity 11b and the oil guide hole 311 are connected in sequence to form an oil guide path.

[0098] In the extension direction of the atomization chamber 11, the oil guide channel 12 has a top channel wall 122 closest to the air outlet channel 13, and a bottom channel wall 121 farthest from the air outlet channel 13, and the top surface of the first oil-absorbing cotton 40 is lower than or equal to the top channel wall 122 of the oil guide channel 12 closest to the air outlet channel 13, and the top surface of the second sealing seat 70 is lower than the top channel wall 122 of the oil guide channel 12 farthest from the air outlet channel 13.

[0099] For the convenience of description and numbering, the top surface of the first oil-absorbing cotton 40 is defined as the first top surface 41 , the peripheral side surface of the first oil-absorbing cotton 40 is defined as the first peripheral side surface 43 , and the top surface of the second sealing seat 70 is defined as the second top surface 71 .

[0100] The first sealing seat 60 is used to seal the end of the bracket 31 close to the air outlet channel 13 to reduce the risk of the aerosol generating matrix in the atomizing chamber 11 leaking from the air outlet channel 13. The second sealing seat 70 is used to seal the end of the bracket 31 away from the air outlet channel 13 to reduce the risk of the aerosol generating matrix in the atomizing chamber 11 leaking from the air inlet 17. The first oil-absorbing cotton 40 is located between the first sealing seat 60 and the second sealing seat 70.

[0101] The aerosol generating matrix input into the first cavity 11a through the oil guiding channel 12 contacts with the first oil absorbing cotton 40 in the first cavity 11a and is absorbed by the first oil absorbing cotton 40, or the aerosol generating matrix input into the first cavity 11a through the oil guiding channel 12 flows from top to bottom into the second cavity 11b, and enters the bracket 31 through the oil guiding hole 311 and is absorbed by the oil guiding cotton 32.

[0102] The first oil-absorbing cotton 40 has the function of absorbing the aerosol-generating substrate, so it can reduce the presence of the aerosol-generating substrate flowing in the first cavity 11a. Therefore, when the oil supply assembly 20 is disassembled, the risk of the aerosol-generating substrate moving out of the oil guide channel 12 is reduced.

[0103] In addition, the top surface of the first oil-absorbing cotton 40 is lower than or equal to the top channel wall 122 of the oil-conducting channel 12 closest to the air outlet channel 13, which can reduce the space occupied by the first oil-absorbing cotton 40 while ensuring that the first oil-absorbing cotton 40 has a good adsorption effect on the aerosol generating matrix.

[0104] The top surface of the second sealing seat 70 is lower than the top channel wall surface 122 of the oil guide channel 12 farthest from the air outlet channel 13, so that the aerosol generating matrix flowing out of all the oil guide channels 12 can flow into the second chamber 11b through the first chamber 11a. The second chamber 11b has a buffering effect on the aerosol generating matrix. The aerosol generating matrix that is not adsorbed by the first oil-absorbing cotton 40 enters the second chamber 11b for buffering, so that the aerosol generating matrix gradually converges in the second chamber 11b until it is adsorbed by the first oil-absorbing cotton 40 or the oil-conducting cotton 32. In this case, on the one hand, the end of the first oil-absorbing cotton 40 close to the first chamber 11a can more evenly adsorb the aerosol generating matrix in the second chamber 11b, so that the aerosol generating matrix can move upward more evenly on the first oil-absorbing cotton 40. On the other hand, the aerosol generating matrix can also more evenly enter the oil-conducting cotton 32 inside the bracket 31 from the oil guide hole 311 on the bracket 31, and be heated by the heating element to atomization.

[0105] See also Figure 3 and Figure 6Furthermore, in some optional embodiments, in the extension direction of the atomization chamber 11, the top surface of the first oil-absorbing cotton 40 is higher than the bottom channel wall 121 of the oil guide channel 12 closest to the air outlet channel 13; the bottom surface of the first oil-absorbing cotton 40 is lower than the top channel wall 122 of the oil guide channel 12 farthest from the air outlet channel 13, and the bottom surface of the first oil-absorbing cotton 40 is higher than the bottom channel wall 121 of the oil guide channel 12 farthest from the air outlet channel 13; the top surface of the second sealing seat 70 is lower than the bottom channel wall 121 of the oil guide channel 12 farthest from the air outlet channel 13.

[0106] For the convenience of description and numbering, the bottom surface of the first oil-absorbing cotton 40 is defined as a first bottom surface 42 .

[0107] Under this design, along the extension direction of the atomization chamber 11, the length of the first oil-absorbing cotton 40 can basically cover all the oil-conducting channels 12, so that the aerosol-generating matrix flowing out of each oil-conducting channel 12 can be quickly absorbed by the first oil-absorbing cotton 40, avoiding oil leakage caused by excessive aerosol-generating matrix flowing in the atomization chamber 11.

[0108] The top surface of the first sealing seat 60 is lower than the bottom channel wall 121 of the oil guide channel 12 farthest from the gas outlet channel 13, so that part of the space of the second cavity 11b is located below the oil guide channel 12 farthest from the gas outlet channel 13, so the second cavity 11b has a better buffering effect.

[0109] See also Figure 3 , Figure 6 , Figure 7 , Figures 9 to 16In some embodiments of the present application, the mounting chamber 15 is located below the atomizing chamber 11, and an air return gap 312 is provided on the outer wall of the bracket 31, and the air return gap 312 is located below the oil guide hole 311. The atomizing device 1 also includes a third sealing seat 80, a second oil-absorbing cotton 50, and a third oil-absorbing cotton 120. The third sealing seat 80 and the second oil-absorbing cotton 50 are both located in the mounting chamber 15, and the third sealing seat 80 is sealed and connected to the cavity wall of the mounting chamber 15. The third sealing seat 80 has a mounting channel 81, and the third sealing seat 80 is provided with a through hole 82 connected to the mounting channel 81. Part of the second oil-absorbing cotton 50 is located in the mounting channel 81, and the rest of it extends out of the mounting channel 81 through the through hole 82. The second oil-absorbing cotton 50 and the hole wall of the through hole 82 define an air return port 83. The second oil-absorbing cotton 50 has a vent hole 51, and the vent hole 51, the air return port 83, the air return gap 312, the second cavity 11b, the first cavity 11a, and each oil guide channel 12 except the oil guide channel 12 farthest from the air outlet channel 13 are connected in sequence, and the end of the center tube 33 away from the air outlet channel 13 extends into the installation channel 81, and the vent hole 51, the installation channel 81, the center channel 331 and the air outlet channel 13 are connected in sequence, and the bottom surfaces of the bracket 31 and the oil-guiding cotton 32 away from the air outlet channel 13 are both in contact with the top surface of the second sealing seat 70. The second oil-absorbing cotton 50 is used to absorb the condensate condensed and returned from the air outlet channel 13, and the third oil-absorbing cotton 120 is arranged around the circumference of the second oil-absorbing cotton 50 and is used to absorb the condensate on the second oil-absorbing cotton 50. The second oil-absorbing cotton 50 and the third oil-absorbing cotton 120 cooperate to have a better effect of absorbing condensate.

[0110] Specifically, in the present application, the sensing air passage 912, the vent hole 51, the mounting channel 81, the central channel 331 and the air outlet channel 13 are sequentially connected to form a sensing air path (such as Figure 6 The induction air path is used to output the air in the installation slot 911 and form a negative pressure, so that the microphone 92 senses the negative pressure. The air inlet 17, the power supply cavity 16, the air passage 913, the vent hole 51, the installation channel 81, the central channel 331 and the air outlet channel 13 are connected in sequence to form an atomization air path (such as Figure 6 The atomizing air path is used to provide air for atomizing and outputting aerosol. The air inlet 17, the power supply cavity 16, the air passage 913, the vent hole 51, the air return port 83, the air return gap 312, the second cavity 11b, the first cavity 11a, and each oil guide channel 12 except the oil guide channel 12 farthest from the air outlet channel 13 are connected in sequence to form an air return path (such as Figure 6 The return air path is used to provide air to the oil supply chamber 215.

[0111] As the working time increases, the aerosol-generating substrate in the oil supply chamber 215 decreases, resulting in negative pressure in the oil supply chamber 215. If the external air cannot be replenished into the oil supply chamber 215 in time, the negative pressure in the oil supply chamber 215 will increase, and eventually the aerosol-generating substrate cannot be introduced into the atomizing chamber 11, resulting in a core-burning phenomenon.

[0112] In the present application, the oil guide channel 12 farthest from the air outlet channel 13 is only used for oil guide, and any other oil guide channel 12 except the oil guide channel 12 farthest from the air outlet channel 13 can be used for both oil guide and air return. During actual operation, each oil guide channel 12 located above the liquid level is located on its respective air return path. After the atomizing device 1 is started, external air enters the oil supply chamber 215 through the air return path to replenish air. In this way, it is beneficial to maintain the balance between the air pressure in the oil supply chamber 215 and the outside world, so that the aerosol generating matrix can be automatically introduced into the atomizing chamber 11, which is beneficial to reduce the risk of core sticking.

[0113] See also Figure 1 , Figures 3 to 5 In some embodiments of the present application, the housing 10 includes an open cavity 14 disposed on one side of the atomization cavity 11, the oil guide channel 12 is located in the open cavity 14 and is disposed toward the opening of the open cavity 14, and the oil supply body 21 is partially installed in the open cavity 14. The oil supply body 21 is partially installed in the open cavity 14, so when the oil outlet hole 211 of the oil supply body 21 cooperates with the oil guide channel 12, the cavity wall of the open cavity 14 can shield the oil outlet hole 211 of the oil supply body 21 and the oil guide channel 12, thereby reducing the risk of the oil supply assembly 20 and the housing 10 being affected by the outside world, and helping to improve the reliability of the oil supply assembly 20 and the housing 10. In addition, the oil supply body 21 partially extends out of the open cavity 14, and the oil supply body 21 can be assembled or disassembled by grabbing or holding this part.

[0114] See also Figure 4 and Figure 5 Please also refer to Figures 17 to 19 In some optional embodiments, the oil supply body 21 is buckled with the housing 10. The oil supply body 21 is buckled with the housing 10, and the oil supply assembly 20 and the housing 10 can also be detachably connected. Combined with the cooperation of the oil guide pipe 18, the oil outlet hole 211 and the elastic seal 22, the connection between the oil supply assembly 20 and the housing 10 is more reliable.

[0115] Specifically, a first buckle part 214 is formed on the oil supply body 21, and a second buckle part 19 is formed on the housing 10, and the first buckle part 214 buckles with the second buckle part 19. The first buckle part 214 can be formed on the side of the oil supply body 21 where the oil outlet hole 211 is provided, or can be formed on the top and bottom surfaces of the oil supply body 21 that are oppositely arranged, or can be formed on the other two side surfaces of the oil supply body 21 that are adjacent to the side surface where the oil outlet hole 211 is provided. The first buckle part 214 and the second buckle part 19 correspond to each other and buckle.

[0116] In some optional embodiments, the oil supply body 21 further includes an oil filling hole 213, and the oil supply assembly 20 further includes an oil filling plug 24, which is installed on the oil supply body 21 and is used to open and close the oil filling hole 213. When the oil filling plug 24 is opened, the aerosol generating substrate can be injected into the oil supply cavity 215 through the oil filling hole 213. When the oil filling plug 24 is closed, the aerosol generating substrate in the oil supply cavity 215 can be sealed.

[0117] In some optional embodiments, the first buckle 214 is formed on the top and bottom surfaces of the oil supply body 21, and the oil outlet hole 211 and the oil filling hole 213 are respectively opened on the two side surfaces of the oil supply body 21. The first buckle 214 cooperates with the second buckle 19, and the oil guide tube 18 cooperates with the oil outlet hole 211, which is conducive to improving the stability of the oil supply assembly 20 and the housing 10, and when the oil supply body 21 is partially installed in the open cavity 14, the oil filling hole 213 is exposed outside the open cavity 14 to facilitate oil filling.

[0118] The above-mentioned atomizer 1, by at least partially disposing the oil supply assembly 20 outside the shell 10, and the oil supply assembly 20 is detachably installed on one side of the atomizer chamber 11, on the one hand, it is convenient to side-mount the oil supply assembly 20 and the shell 10, thereby improving the assembly efficiency of the atomizer 1; on the other hand, the oil supply assembly 20 and / or the components in the shell 10 can be reused by disassembly, thereby saving resources and reducing the cost of use.

[0119] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0120] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
