Referring to the drawings, an embodiment of the present application provides an electronic atomization device 100, which includes a first heating component 10 and a second heating component 20.

In embodiments of the present application, the electronic nebulizing device 100 may refer to a device that generates an aerosol using a nebulizable matrix in order to generate an aerosol that may be inhaled directly into the lungs of a user through the mouth of the user.

In embodiments of the present application, an nebulizable matrix may refer to a substance capable of generating an aerosol (aerosol). The aerosol may comprise volatile compounds. The nebulizable matrix may be solid or liquid. When the nebulizable matrix is a solid, for example, it may be in the form of a cake to increase its contact area with the heating element, it may of course also be in the form of a cylindrical strip, or a sphere, etc., without being particularly limited. The nebulizable matrix may comprise solid substances based on tobacco flakes, cut filler, reconstituted tobacco and the like as cigarette raw materials, and the liquid nebulizable matrix may comprise liquid compositions based on nicotine, tobacco extracts and/or various flavourants. However, the scope of the present disclosure is not limited to the above examples.

In other embodiments, the electronic atomizing device 100 of the present application may be applied to the medical field, and the nebulizable matrix 200 may be a liquid medicine or a nutrient solution, etc., which contains an active ingredient having a therapeutic effect or a nutritional value.

In the embodiments of the present application, the first heating assembly 10 and the second heating assembly 20 refer to assemblies that are capable of heating an nebulizable substrate. The heating method is not limited to resistance heating, electromagnetic induction heating, and the like.

Referring to fig. 3 and 4, the first heating element 10 has a first heating surface 11, and the second heating element 20 is connected to the first heating element 10 and has a second heating surface 21. Wherein the first heating surface 11 is opposite to the second heating surface 21 and spaced apart from the second heating surface to define a heating chamber 30 therebetween.

The first heating surface 11 and the second heating surface 21 are surfaces capable of diffusing heat to the nebulizable substrate. For example, the first heating surface 11 and the second heating surface 21 can be directly contacted with the nebulizable substrate 200 to perform heating, or the first heating surface 11 and the second heating surface 21 can be spaced opposite to the nebulizable substrate 200 to perform heating by transferring heat through air, which is not particularly limited.

According to the electronic atomization device 100, the first heating surface 11 of the first heating component 10 and the second heating surface of the second heating component 20 are opposite and are arranged at intervals, and the heating cavity 30 is defined between the first heating surface 11 and the second heating surface, when the electronic atomization device 100 is used for atomizing the nebulizable substrate 200, the first heating surface 11 and the second heating surface 21 can simultaneously apply heated heat to the nebulizable substrate 200 relatively, so that the heating area of the nebulizable substrate 200 is increased, the heated temperature field is more uniform, the consistency of the heating temperature is improved, and the nebulization substrate 200 is further facilitated to be atomized out of effective components, and the generation of harmful substances is reduced.

Referring again to fig. 1 and 2, in particular to the embodiment of the present application, the electronic atomization device 100 further includes a power supply assembly 40 and an atomizer 50 connected to the power supply assembly 40. Specifically, the atomizer 50 is detachably provided to the power supply assembly 40.

The power supply assembly 40 at least includes a power supply 41 for supplying electric power for heating to the first heating assembly 10 and the second heating assembly 20. The atomizer 50 comprises a nozzle assembly 51, the nozzle assembly 51 comprising at least a nozzle 511, the nozzle 511 having a suction channel 5111 for delivering aerosol generated by heating the nebulizable substrate 200 during the suction by a user.

In some embodiments, at least one of the first heating assembly 10 and the second heating assembly 20 is mounted to the nozzle assembly 51 to constitute the atomizer 50 described above. For example, the first heating assembly 10 and the second heating assembly 20 are each mounted to the nozzle assembly 51, or one of the first heating assembly 10 and the second heating assembly 20 is mounted to the nozzle assembly 51, and the other is mounted to the power supply assembly 40. Because the power supply assembly 40 has more components and more complex assembly structure, and the suction nozzle assembly 51 has a relatively simple structure and easy assembly, the assembly of at least one of the first heating assembly 10 and the second heating assembly 20 to the suction nozzle assembly 51 can reduce the overall assembly difficulty of the electronic atomizing device 100 and improve the assembly efficiency.

Further, when the first heating assembly 10 and the second heating assembly 20 are both assembled to the nozzle assembly 51, one of the first heating assembly 10 and the second heating assembly 20 can be detached from the nozzle assembly 51, so that the heating cavity 30 is exposed outside the nozzle assembly 51.

In this way, one of the first heating assembly 10 and the second heating assembly 20 can be repeatedly assembled or disassembled relative to the suction nozzle assembly 51, and after the disassembly and separation, the heating cavity 30 is exposed, so that the fouling phenomenon generated by long-time heating on the first heating assembly 10 and the second heating assembly 20 can be conveniently cleaned, and the harmful substances generated by fouling during high-temperature heating can be reduced.

Specifically, one of the first heating assembly 10 and the second heating assembly 20 may be detachably assembled with respect to the suction nozzle assembly 51, and an elastic sealing ring may be sleeved on the peripheries of the first heating assembly 10 and the second heating assembly 20, so that the elastic sealing ring is in interference fit with the suction nozzle assembly 51, or may be in threaded fit, snap fit, toggle fit, or the like.

In other embodiments, when one of the first heating assembly 10 and the second heating assembly 20 is mounted on the suction nozzle assembly 51 and the other is mounted on the power supply assembly 40, the heating chamber 30 is exposed outside the suction nozzle assembly 51 or the power supply assembly 40 when the suction nozzle assembly 51 is detached from the power supply assembly 40.

In this way, after the suction nozzle assembly 51 is detached from the power supply assembly 40, the heating cavity 30 is exposed, so that the fouling phenomenon generated by long-time heating on the first heating assembly 10 and the second heating assembly 20 can be conveniently cleaned, and the harmful substances generated by fouling during high-temperature heating can be reduced.

Referring to fig. 5, in some embodiments, the first heating assembly 10 includes a first heating element 12, where the first heating element 12 has a first heating surface 11. Alternatively, the first heating element 12 may be a first heating plate having a first heating surface 11.

The first heating surface 11 referred to herein should be located on a large surface of the first heat patch.

Therefore, by providing the first heating element 12 as a first heating sheet in a sheet shape, the first heating element 12 can be made to have a larger heating area, heating efficiency is improved, and the overall structure is simplified. In other embodiments, the first heating element 12 may be cylindrical, elongated, or the like, and is not particularly limited.

In other embodiments, the second heating assembly 20 includes a second heating member 22, the second heating member 22 having a second heating surface 21. Alternatively, the second heating member 22 may be a second heating plate having the second heating surface 21.

Similarly, by arranging the second heating element 22 as a second heating sheet, the second heating element 22 can have a larger heating area, thereby improving the heating efficiency and simplifying the overall structure. In other embodiments, the second heating element 22 may be cylindrical, elongated, or the like, and is not particularly limited.

In other embodiments, the first heating assembly 10 comprises a first heating plate and the second heating assembly 20 comprises a second heating plate.

In some embodiments, the first heating assembly 10 further comprises a first fitting 13, and the first heating element 12 is fitted to the first fitting 13. By arranging the first assembly part 13 to assemble the first heating element 12, the first heating element 12 can be installed more stably, and the heating stability and reliability of the first heating element 12 are improved.

Likewise, the second heating assembly 20 further includes a second fitting 23, and the second heating member 22 is fitted to the second fitting 23.

Further, the first fitting 13 is disposed opposite to the second fitting 23, the first heating element 12 is disposed at an end of the first fitting 13 facing the second fitting 23, and the second heating element 22 is disposed at an end of the second fitting 23 facing the first fitting 13.

Thus, when the first fitting member 13 is disposed opposite to the second fitting member 23, the first heating member 12 and the second heating member 22 can be disposed opposite to each other, thereby enabling the heating chamber 30 to be formed rapidly.

In some embodiments, the first fitting 13 is recessed toward one end of the second fitting 23 to form a first cavity, and the first heating element 12 is disposed within the first cavity, the first cavity forming at least a portion of the heating cavity 30.

By providing the first cavity, on the one hand, a mounting space for the first heating member 12 can be provided, and on the other hand, at least part of the heating chamber 30 can be formed, simplifying the overall structure of the first heating assembly 10.

Specifically, the first heating element 12 is disposed at the bottom of the first cavity, such that a side of the first heating element 12 facing away from the bottom wall of the first cavity encloses with a side wall of the first cavity to form at least a portion of the heating cavity 30. In another embodiment, the first heating element 12 may be disposed on a side portion of the first cavity, and at least a portion of the heating cavity 30 is formed by enclosing the side wall of the first heating element 12 with the side wall and the bottom wall of the first cavity. In other embodiments, the first heating element 12 may be disposed in the first cavity in a combination of the above two manners, which is not particularly limited.

In some embodiments, the first cavity may also be used only to provide the first heating element 12 without forming at least part of the heating cavity 30.

In other embodiments, the second fitting 23 is recessed toward one end of the first fitting 13 to form a second cavity 231, the second heating element 22 is disposed within the second cavity 231, and the second cavity 231 forms at least a portion of the heating cavity 30.

By providing the second recess 231, on the one hand, a space for mounting the second heating member 22 can be provided, and on the other hand, at least part of the heating chamber 30 can be formed, simplifying the overall structure of the second heating member 22.

Specifically, the second heating element 22 is disposed at the bottom of the second cavity 231, such that at least a portion of the heating cavity 30 is defined by a side of the second heating element 22 facing away from the bottom wall of the first cavity 231 and a side wall of the second cavity 231. In another embodiment, the second heating element 22 may be disposed on a side of the second cavity 231, and at least a portion of the heating cavity 30 is formed by enclosing between the sidewall of the second heating element 22 and the sidewall and bottom wall of the second cavity 231. In other embodiments, the second heating element 22 may be disposed in the second cavity 231 in a combination of the above two manners, which is not particularly limited.

In some embodiments, the second cavity 231 may also be used only to provide the second heating element 22 without forming at least part of the heating cavity 30.

In other embodiments, the first cavity forms part of the heating cavity 30 and the second cavity 231 forms part of the heating cavity 30, the first cavity and the second cavity being capable of combining to form the heating cavity 30.

Referring to fig. 2, in the embodiment of the present application, the suction nozzle assembly 51 has a suction nozzle end, and the second heating assembly 20 is further away from the suction nozzle end than the first heating assembly 10, and thus, the heating chamber 30 is formed on the second concave chamber 231, so that an end of the second concave chamber 231 facing the suction nozzle end has an opening, that is, an upper end of the second concave chamber 231 has an opening, thereby facilitating the receiving of the nebulizable substrate 200 from the outside into the second concave chamber 231, and the nebulizable substrate 200 can also be provided with a supporting force in a gravitational direction in the second concave chamber 231 after entering the second concave chamber 231, so that the nebulizable substrate 200 can be smoothly mounted into the heating chamber 30 of the electronic nebulizing device 100.

In particular, in the embodiment of the present application, the first cavity is only used for setting the first heating element 12, and the second heating element 22 is set at the bottom of the second cavity 231, so that a side of the second heating element 22 facing away from the bottom wall of the first cavity 231 forms a heating cavity 30 with the side wall of the second cavity 231 and the first heating element 12.

In some embodiments, the electronic atomizing device 100 further comprises an nebulizable substrate 200, and both the first heating surface 11 and the second heating surface 21 are capable of contacting the nebulizable substrate 200.

Since the first heating surface 11 and the second heating surface 21 are disposed opposite to each other and both contact the nebulizable substrate 200, the nebulizable substrate 200 can be clamped and fixed in the heating chamber 30, so that the first heating surface 11 and the second heating surface 21 can be stably contacted with the nebulizable substrate 200, and further, the reliability of heating and nebulization can be improved.

Specifically, when the first heating element 10 and the second heating element 20 are both assembled to the nozzle assembly 51, the first heating surface 11 and the second heating surface 21 can clamp the nebulizable substrate 200 after the assembly of the first heating element 10 and the second heating element 20, or when one of the first heating element 10 and the second heating element 20 is assembled to the nozzle assembly 51 and the other is assembled to the power supply assembly 40, the first heating surface 11 and the second heating surface 21 can clamp the nebulizable substrate 200 after the assembly connection of the nozzle assembly 51 and the power supply assembly 40.

In some embodiments, the first heating assembly 10 further comprises a first thermal shield 14, the first thermal shield 14 being disposed on a side of the first heating member 12 facing away from the heating chamber 30.

The first heat insulator 14 is a member having a function of insulating heat, and can relatively insulate heat generated by the first heater 12 from the outside environment of the first heat insulator 14, concentrate the heat in a space for generating heat, and reduce wasteful heat loss to the outside.

By arranging the first heat insulating member 14 on the side, away from the heating cavity 30, of the first heating member 12, heat insulation and heat preservation can be performed on the first heating member 12, so that heating efficiency of the nebulizable matrix 200 is improved.

Optionally, the first thermal insulation member 14 comprises a first aerogel member provided on a side of the first heating member 12 facing away from the heating chamber 30.

The first aerogel member can not only provide an effective heat insulating effect, but also protect the first heating member 12 to some extent due to the elastic deformation thereof.

In other embodiments, the second heating assembly 20 further includes a second thermal shield 24, the second thermal shield 24 being disposed on a side of the second heating member 22 facing away from the heating chamber 30.

By providing the second heat insulating member 24 on the side of the second heating member 22 facing away from the heating chamber 30, the second heating member 22 can be heat-insulated, thereby improving the heating efficiency of the nebulizable matrix 200.

Optionally, the second insulation 24 comprises a second aerogel element disposed on a side of the second heating element 22 facing away from the heating chamber 30.

The second aerogel member can not only provide an effective heat insulating effect, but also protect the second heating member 22 to some extent due to elastic deformation.

In other embodiments, the electronic atomizing device 100 may include both the first thermal shield 14 and the second thermal shield 24. Alternatively, the first insulation 14 comprises a first aerogel member and the second insulation 24 comprises a second aerogel member.

In some embodiments, the first heating assembly 10 has an aerosol passage 15 and the second heating assembly 20 has an air inlet passage 25, and the heating chamber 30 communicates the aerosol passage 15 with the air inlet passage 25.

The aerosol passage 15 is for delivering aerosol and the air inlet passage 25 is for introducing an ambient air flow into the heating chamber 30.

Thus, when the user sucks, the external air flow can enter the heating cavity 30 under the guiding action of the air inlet channel 25, so that the aerosol in the heating cavity 30 is conveyed along with the air flow entering the aerosol channel 15, and then sucked by the user.

Specifically, an air intake passage 25 is formed between the second fitting 23 and the second heating member 22, and the air intake passage 25 is provided around the second heating surface 21.

In this way, the air entering the air inlet passage 25 can enter the heating chamber 30 in the circumferential direction, and thus the air can be fully introduced into the heating chamber 30, and the heating uniformity can be improved.

Specifically, the air intake passage 25 may be entirely surrounded, or may be a surrounding portion, and may further include a plurality of sub-air intake passages that are surrounded at intervals, which is not particularly limited.

In the embodiment of the present application, the sidewall of the second recess 231 forms an air intake passage 25 between the first heating member 22 in the circumferential direction.

Specifically, the communication passage 232 includes a communication hole. In the embodiment of the present application, the communication passage 232 includes a plurality of communication passages 232 spaced apart from each other, and each communication passage 232 communicates the intake passage 25 with the outside.

Referring to fig. 3 again, in some embodiments, the first heating element 12 is provided with a first aerosol through hole 121, and the first aerosol through hole 121 is a part of the aerosol passage 15.

In this way, the aerosol in the heating chamber 30 can be directly delivered to the user through the first aerosol through hole 121, so that the formation mode of the aerosol channel 15 is simplified, and the aerosol can be rapidly provided to the user.

Further, the first heat insulator 14 is provided with a second aerosol through hole 141, and the second aerosol through hole 141 forms part of the aerosol passage 15 and communicates with the first aerosol through hole 121.

Further, a third aerosol through hole 131 is formed in the first fitting 13, and the third aerosol through hole 131 forms part of the aerosol passage 15 and communicates with the second aerosol through hole 141.

In the embodiment of the present application, when a user sucks, the external airflow can enter the heating cavity 30 under the guiding action of the air inlet channel 25, so that the aerosol in the heating cavity 30 sequentially enters the first aerosol through hole 121, the second aerosol through hole 141 and the third aerosol through hole 131 along with the airflow, and then enters the suction channel 5111 for the user to suck.
