[0052] ​​​The electronic atomization device 300 is used for atomizing an aerosol generating substrate. The aerosol generating substrate can be a liquid medicine, a nutrient solution, or a combined liquid substrate containing a special aroma, etc. The atomization method can be heating atomization and / or non-heating atomization. The heating atomization includes resistance heating, electromagnetic heating, laser heating, infrared heating, microwave heating, etc. The non-heating atomization includes ultrasonic atomization, mechanical vibration atomization, etc.

[0053] Specifically, the electronic atomization device 300 includes an atomizer 100 and a main machine 200 electrically connected to each other. The atomizer 100 is used for storing an aerosol generating substrate and atomizing the aerosol generating substrate to form an aerosol for a user. The specific structure and function of the atomizer 100 can refer to the specific structure and function of the atomizer 100 involved in the following embodiments, and the same or similar technical effects can be achieved, which will not be described here.

[0054] The main machine 200 at least includes a battery 201, a controller (not shown), and a needle 202. The battery 201 is used to provide power for the operation of the atomizer 100, so that the atomizer 100 can atomize the aerosol generating substrate to form an aerosol. The controller is used to control the battery 201 to provide power for the atomizer 100. The needle 202 includes a positive needle 2021 and a negative needle 2022, which are electrically connected to the atomizer 100 and the battery 201, respectively, to transmit the power on the battery 201 to the atomizer 100. The main machine 200 further includes a bracket (not shown), an airflow sensor (not shown), and other elements.

[0055] The atomizer 100 and the main machine 200 can be integrally arranged or detachably connected, which is designed according to specific needs.

[0056] In combination Figure 4 , Figure 4 For Figure 1 The electronic atomization device shown in the figure is a cross-sectional view along the A-A line. The atomizer 100 includes an atomization assembly 10, an atomization tube 20, and a mounting seat 30. Specifically, the atomization tube 20 has an opposite nozzle end 21 and an opening end 22, the mounting seat 30 covers the opening end 22 of the atomization tube 20, and has a third accommodating cavity A3, and the atomization assembly 10 is arranged in the third accommodating cavity A3. The atomization tube 20 has an atomization channel B in communication with the outside, and the atomization assembly 10 is used for atomizing the aerosol generating substrate to generate an aerosol, and the aerosol generated on the atomization assembly 10 is guided out through the atomization channel B.

[0057] In an embodiment, the mounting base 30 cooperates with the atomization tube 20 to define a liquid storage cavity C for storing the aerosol generating substrate; the mounting base 30 further has a liquid guide tube 301 having a mounting cavity D in communication with the third accommodating cavity A3, and the mounting cavity D is in fluid communication with the liquid storage cavity C. The atomizer 100 further comprises a liquid guide cotton 40 at least partially in contact with the atomization assembly 10 to transfer the aerosol generating substrate in the liquid storage cavity C to the atomization assembly 10 for atomization, and a flattening piece 50 disposed on a side of the liquid guide cotton 40 away from the atomization assembly 10 and in abutment with the liquid guide cotton 40 to flatten at least a portion of the liquid guide cotton 40 in contact with the atomization assembly 10, so that the portion of the liquid guide cotton 40 in contact with the atomization assembly 10 is uniformly laid on the atomization assembly 10 under stress, facilitating uniform distribution of the aerosol generating substrate.

[0058] In an embodiment, since the atomization assembly 10 atomizes the aerosol generating substrate by ultrasonic atomization or mechanical vibration atomization, the atomization blade 12 of the atomization assembly 10 needs to be vibrated at high frequency and small amplitude during atomization. To avoid affecting atomization of the atomization assembly 10, the flattening piece 50 is made of a material with elasticity, such as silicone or rubber.

[0059] Referring to Figure 4 and Figure 5 , Figure 5 is a structural schematic view of an embodiment of the liquid guide cotton provided in the present application; in an embodiment, the liquid guide cotton 40 comprises a liquid guide side wall 41 and an atomization bottom wall 42, the liquid guide side wall 41 is disposed in the mounting cavity D and is in fluid communication with the liquid storage cavity C, the atomization bottom wall 42 is in contact with the atomization blade 12 in the atomization assembly 10, and the flattening piece 50 is disposed on a side of the atomization bottom wall 42 away from the atomization blade 12. It should be noted that the liquid guide side wall 41 and the atomization bottom wall 42 are made of the same material and both have atomization and liquid guiding effects. Since the atomization bottom wall 42 is in direct contact with the atomization blade 12, the atomization blade 12 mainly atomizes the aerosol generating substrate on the atomization bottom wall 42, while the liquid guide side wall 41 is not in direct contact with the atomization blade 12 and is mainly used to transfer the aerosol generating substrate in the liquid storage cavity C to the atomization bottom wall 42. Specifically, the liquid guide cotton 40 is an integrally formed barrel-shaped structure, the liquid guide side wall 41 is cylindrical and has two opposite openings 411 at the bottom, and the atomization bottom wall 42 is circular. Further, the liquid guide side wall 41 further has a gap in communication with the openings 411, and the liquid guide side wall 41 can be unfolded at the gap position to facilitate installation of the flattening piece 50.

[0060] In combination with Figure 6 , Figure 6The structure diagram of an embodiment of the flattening piece provided in the present application; in order to achieve better atomization effect, the flattening piece 50 comprises an abutting portion 51 and a connecting portion 52, the abutting portion 51 abuts against the atomization bottom wall 42 and is adapted to the shape and size of the atomization bottom wall 42, so as to flatten the whole atomization bottom wall 42 on the atomization sheet 12. For example, the shape and size of the abutting portion 51 are completely the same as those of the atomization bottom wall 42; or the shape of the abutting portion 51 is the same as that of the atomization bottom wall 42, but the size of the abutting portion 51 is slightly smaller than that of the atomization bottom wall 42, so as to facilitate the installation of the flattening piece 50 into the liquid guiding cotton 40. The connecting portion 52 is located at one end of the abutting portion 51 away from the atomization sheet 12, and the connecting portion 52 is fixedly connected with other components in the atomizer 100, so as to firmly fix the abutting portion 51 and the atomization bottom wall 42 on the atomization sheet 12, and avoid the displacement of the atomization sheet 12 and / or the atomization bottom wall 42 in the vibration process, thereby affecting the atomization effect.

[0061] It can be understood that the atomization bottom wall 42 is located between the atomization sheet 12 and the flattening piece 50, the greater the pressure applied by the flattening piece 50 on the atomization bottom wall 42, i.e. the smaller the distance between the flattening piece 50 and the atomization surface of the atomization sheet 12, the thinner the thickness of the atomization bottom wall 42 is compressed, and the pore diameter of the micropores on the atomization bottom wall 42 is compressed and reduced, so the liquid guiding resistance of the atomization bottom wall 42 is greater, and its liquid storage capacity is correspondingly smaller. Therefore, the liquid guiding speed and the liquid content of the atomization bottom wall 42 can be adjusted by adjusting the pressure of the flattening piece 50 on the atomization bottom wall 42, and the purpose of adjusting the atomization amount of the atomization sheet 12 can be achieved.

[0062] In combination with Figures 7-9 , Figure 7 The structure diagram of an embodiment of the mounting top seat provided in the present application; Figure 8 For Figure 7 The sectional view of the mounting bottom seat shown in the figure along the line A-A; Figure 9 The structure diagram of an embodiment of the mounting bottom seat provided in the present application.

Of course, it can also be that when the mounting top seat 31 is connected with the mounting bottom seat 32, the mounting top seat 31 is at least partially inserted or rotated into the mounting bottom seat 32.

[0063] Specifically, since the flattening piece 50 is fixed to the atomization bottom wall 42 on the side away from the atomization sheet 12, when the atomization sheet 12 moves towards the flattening piece 50 along with the mounting base 32, or when the flattening piece 50 moves towards the atomization sheet 12 along with the mounting top base 31, the flattening piece 50 exerts pressure on the atomization bottom wall 42, so that the thickness of the atomization bottom wall 42 decreases; when the atomization sheet 12 moves away from the flattening piece 50 along with the mounting base 32, or when the flattening piece 50 moves away from the atomization sheet 12 along with the mounting top base 31, the flattening piece 50 releases pressure on the atomization bottom wall 42, so that the thickness of the atomization bottom wall 42 increases, thereby achieving the purpose of adjusting the amount of atomization mist generated on the atomization sheet 12.

[0064] In an embodiment, one of the mounting top base 31 and the mounting base 32 is provided with a positive thread, and the other is provided with a reverse thread, and the mounting top base 31 and the mounting base 32 are connected through the threads. The depth of the mounting base 32 screwed into the mounting top base 31 is adjusted, so as to achieve the purpose of adjusting the amount of atomization mist generated on the atomization sheet 12. In this embodiment, the air inlet hole 304 is provided on the mounting top base 31, and the air inlet hole 304 is used to introduce external air into the atomizer 100 when the atomizer 100 is working, and further carry the generated aerosol out of the atomization channel B.

[0065] Specifically, one end of the mounting top base 31 is provided with a first accommodating groove 311, the groove opening of the first accommodating groove 311 faces the mounting base 32, and the inner surface of the side wall of the first accommodating groove 311 is provided with a positive thread; one end of the mounting base 32 is provided with a second accommodating groove 321, the groove opening of the second accommodating groove 321 faces the mounting top base 31, and the outer surface of the side wall of the second accommodating groove 321 is provided with a reverse thread, and the mounting base 32 and the mounting base 32 are connected through the threads, the first accommodating groove 311 and the second accommodating groove 321 cooperatively define a third accommodating cavity A3, and the atomization assembly 10 is accommodated in the third accommodating cavity A3.

[0067] Further, a liquid guide fixing member 303 is further arranged between the liquid guide cotton 40 and the liquid guide pipe 301, and is used to fix the liquid guide cotton 40 in the mounting cavity D, wherein the liquid guide fixing member 303 is a tubular body sleeved outside the liquid guide cotton 40 and the side wall of which is provided with a liquid guide hole corresponding to the liquid inlet hole 302; the liquid guide pipe 301 is sleeved outside the liquid guide fixing member 303.

[0068] The atomizer 100 further comprises a porous base 60 inserted into the liquid guiding cotton 40, one end of the porous base 60 abutting against the flattening piece 50, and the other end abutting against the atomizing tube 20, so as to fix the flattening piece 50. In this embodiment, the porous base 60 can be a hollow cylindrical porous ceramic, and the porous base 60 can also be used to store liquid from the liquid guiding cotton 40.

[0069] In some embodiments, the porous base 60 can be further provided with a heating wire (not shown in the figure), which is at least partially embedded in the porous base 60, for preheating the high-viscosity aerosol generating substrate under the condition of being powered on, so that the preheated aerosol generating substrate with reduced viscosity can be more smoothly delivered to the atomizing surface of the atomizing sheet 12. In other embodiments, the heating wire can also be at least partially arranged on the surface of the porous base 60 close to the airflow channel, for atomizing the aerosol generating substrate or heating the aerosol, so as to achieve better atomization amount and smoking taste, and avoid the influence of too small aerosol amount or too low temperature on user experience.

The second passage segment 532 is arranged along the axial direction X. The first passage segment 531 is a groove on the surface of the abutting portion 51 close to the atomization bottom wall 42. The extension direction of the groove is perpendicular to the axial direction X. The opening 411 corresponds to the passage opening (i.e., the two ports of the groove) of the first passage segment 531.

[0074] In an embodiment, in order to improve the atomization efficiency, the groove penetrates through the abutting portion 51 along the longitudinal direction of the abutting portion 51. The opening 411 is two, and the two openings 411 are respectively arranged corresponding to the two side ports of the groove.

[0075] In an embodiment, in order to make the atomizer 100 have an attractive appearance and facilitate standardized production, the atomization tube 20, the mounting seat 30, and the atomization assembly 10 are coaxially arranged. The porous base 60, the liquid guide cotton 40, and the flattening piece 50 are arranged on the axis of the mounting seat 30.

[0076] See Figure 4 , Figure 11 and Figure 12 , Figure 11 is a structural schematic view of an embodiment of the inhaler provided in the present application; Figure 12 is a sectional view of the inhaler shown in Figure 11 along the line A-A. In an embodiment, the atomization tube 20 includes an inhaler 23 and an inhaler seat 24. The inhaler 23 serves as the inhaler end 21 of the atomization tube 20. The inhaler seat 24 serves as the opening end 22 of the atomization tube 20. The two ends of the inhaler seat 24 are respectively connected to the inhaler 23 and the mounting top seat 31. The inhaler 23, the inhaler seat 24, and the mounting top seat 31 cooperatively define the liquid storage cavity C. By dividing the atomization tube 20 into two independent parts, the inhaler 23 and the inhaler seat 24 can be connected by buckling or screwing. Therefore, the inhaler 23 can be replaced individually. This avoids the dirt and damage of the inhaler 23 caused by long-term use, which affects the health of the user and reduces the replacement cost.

[0077] In addition, the material of the mouthpiece seat 24 can be transparent glass or transparent plastic to facilitate the user to observe the content of the aerosol generating substrate.

[0078] In an embodiment, the mouthpiece 23 is provided with a first connecting structure 231 near one end of the mounting top seat 31, and the liquid guide pipe 301 is also provided with a second connecting structure 305 at an end away from the third accommodating cavity A3. The liquid guide pipe 301 is connected to the mouthpiece 23 through the connecting structures by penetrating the mouthpiece seat 24. The connecting mode of the first connecting structure 231 and the second connecting structure 305 can be snap connection or threaded connection. In the present embodiment, one of the first connecting structure 231 and the second connecting structure 305 is a positive thread, and the other is a reverse thread. The first connecting structure 231 and the second connecting structure 305 are screw connected.

[0079] Please continue to see Figure 3 To avoid liquid leakage, the connection between the mouthpiece 23 and the mouthpiece seat 24 is provided with a first sealing member 25, the connection between the mouthpiece seat 24 and the mounting top seat 31 is provided with a second sealing member 26, and the connection between the mouthpiece 23 and the mounting cavity D is provided with a third sealing member 27. The first sealing member 25, the second sealing member 26 and the third sealing member 27 can be silica gel or rubber.

[0080] Specifically, the atomizer 100 provided by the present application can flatten the atomizing bottom wall 42 on the atomizing sheet 12 through the flattening member 50, which is conducive to the uniform atomization of the atomizing sheet 12. In addition, the mounting seat 30 includes a mounting top seat 31 and a mounting bottom seat 32. When the mounting top seat 31 and the mounting bottom seat 32 are connected, the insertion depth of the two can be adjusted to change the pressure of the flattening member 50 on the atomizing bottom wall 42, change the thickness of the atomizing bottom wall 42, and further adjust the liquid delivery speed and liquid content of the atomizing bottom wall 42, so as to achieve the purpose of adjusting the amount of mist atomized on the atomizing sheet 12.

[0081] See Figures 13-15 , Figure 13 The structure schematic view of an embodiment of the atomizing assembly provided by the present application; Figure 14 The structure schematic view of an embodiment of the atomizing assembly provided by the present application; Figure 13 The sectional view of the atomizing assembly shown in FIG. 4 along the line A-A; Figure 15 The sectional view of the atomizing assembly shown in FIG. 4 along the line A-A; Figure 13 The structure exploded view of the atomizing assembly shown in FIG. 4.

[0082] The atomization assembly 10 provided by the application comprises a fixed shell 11, an atomization sheet 12, a first conductive assembly 13 and a second conductive assembly 14. The fixed shell 11 and / or the first conductive assembly 13 has a first accommodating cavity A1, the atomization sheet 12 and the second conductive assembly 14 are arranged in the first accommodating cavity A1, and the first conductive assembly 13 and the second conductive assembly 14 are respectively electrically connected with two opposite surfaces of the atomization sheet 12 to supply power to the atomization sheet 12. Specifically, the atomization sheet 12 and the second conductive assembly 14 are arranged in the first accommodating cavity A1, and the first conductive assembly 13, the second conductive assembly 14 and the fixed shell 11 cooperate to fix the atomization sheet 12, and the fixed shell 11 fixes the first conductive assembly 13 and the second conductive assembly 14 at a fixed relative position and insulates the first conductive assembly 13 and the second conductive assembly 14, so as to form a modular atomization assembly 10, that is, the atomization assembly 10 is an independent assembly, which can be assembled independently and then arranged in a third accommodating cavity A3 as a whole, thereby facilitating the installation and replacement of the atomization assembly 10 and being conducive to standardized and mechanized production.

[0083] In some embodiments, the fixed shell 11 has a first accommodating cavity A1, and at least part of the first conductive assembly 13, the second conductive assembly 14 and the atomization sheet 12 are accommodated in the first accommodating cavity A1, and the fixed shell 11 fixes the first conductive assembly 13 and the second conductive assembly 14 at a fixed relative position and insulates the first conductive assembly 13 and the second conductive assembly 14. In other embodiments, the first conductive assembly 13 has a first accommodating cavity A1, and at least part of the fixed shell 11, the second conductive assembly 14 and the atomization sheet 12 are accommodated in the first accommodating cavity A1, and the fixed shell 11 fixes the first conductive assembly 13 and the second conductive assembly 14 at a fixed relative position and insulates the first conductive assembly 13 and the second conductive assembly 14. In other embodiments, the fixed shell 11 and the first conductive assembly 13 cooperate to form a first accommodating cavity A1, and the second conductive assembly 14 and the atomization sheet 12 are accommodated in the first accommodating cavity A1, and the fixed shell 11 fixes the first conductive assembly 13 and the second conductive assembly 14 at a fixed relative position and insulates the first conductive assembly 13 and the second conductive assembly 14. Specifically, the selection can be made according to actual needs.

[0084] The atomization sheet 12 can be a piezoelectric ceramic flat sheet. The piezoelectric ceramic flat sheet has two surfaces provided with conductive surfaces that are not electrically connected with each other, and different conductive surfaces can be respectively electrically connected with two electrodes to realize high-frequency vibration of the atomization sheet 12.

[0085] In an embodiment, the fixed shell 11 has a first accommodating cavity A1, the first conductive assembly 13 includes a first conductive piece 131 and a first connecting piece 132 detachably connected with the first conductive piece 131, and the second conductive assembly 14 includes a second conductive piece 141 and a second connecting piece 142 detachably connected with the second conductive piece 141. The first conductive piece 131 and the second conductive piece 132 are insulatively arranged in the first accommodating cavity A1 and are respectively electrically connected with two opposite surfaces of the atomization piece 12, and the first connecting piece 132 and the second connecting piece 142 are insulatively arranged at the same end of the fixed shell 11 and are used for abutting against the needle 202 of the host 200. The first conductive piece 131 and the first connecting piece 132 are detachably connected, and the second conductive piece 141 and the second connecting piece 142 are detachably connected, so that when the conductive performance of the first connecting piece 132 and the second connecting piece 142 deteriorates, the first connecting piece 132 and the second connecting piece 142 can be conveniently replaced and cost can be saved.

[0086] In the embodiment, the first conductive piece 131 includes a metal sleeve, and the first connecting piece 132 includes a metal ring; the second conductive piece 141 includes a metal spring, and the second connecting piece 142 includes a metal sheet; the metal ring is arranged around the metal sheet at intervals, the metal sleeve is arranged around the metal spring, and the metal sleeve abuts against one side of the atomization piece 12 away from the flexible fixing piece 15; and the two ends of the metal spring respectively abut against the atomization piece 12 and the metal sheet. Specifically, the opposite sides of the atomization piece 12 respectively abut against the metal sleeve and the metal spring, and when the metal spring exerts a force on the atomization piece 12 in a direction away from the metal spring, the metal sleeve limits the atomization piece 12 to fix the relative position of the atomization piece 12 in the first accommodating cavity A1, and because one side of the atomization piece 12 abuts against the metal sleeve, the metal spring can be correspondingly contracted or stretched when the atomization piece 12 works, so as not to affect the work of the atomization piece 12.

[0087] In addition, the metal sheet is circular, the metal sleeve and the metal ring are circular rings, one of the metal ring and the metal sheet is used for abutting against the positive needle 2021 on the host 200, and the other is used for abutting against the negative needle 2022, and the metal ring and the metal sheet are coaxially arranged, so that when the atomization assembly 10 abuts against the needle 202 on the host 200, even if the atomization assembly 10 is rotated at an arbitrary angle along the circumferential direction of the atomization assembly 10 at the current position, the effective electrical connection between the metal sheet and the positive needle 2021 and the effective electrical connection between the metal ring and the negative needle 2022 can be guaranteed, and the directionless and leadless assembly of the atomization assembly 10 on the host 200 is realized.

[0088] The first conductive part 131 has a limiting part 1311 close to one end of the mounting top base 31. The limiting part 1311 extends inward from the side wall of the first conductive part 131 and abuts against the surface of the atomizing piece 12 close to the mounting top base 31. The second conductive part 141 abuts against the surface of the atomizing piece 12 away from the mounting top base 31. It can be understood that the limiting part 1311 abuts against and limits the atomizing piece 12, and at the same time, electrically connects one metal surface of the atomizing piece 12, that is, realizes the electrode electrical contact. At the same time, the second conductive part 141 adopts a metal spring, realizing the flexible electrical contact to the other metal surface of the atomizing piece 12. Therefore, the atomizing piece 12 realizes the electrode connection without using the electrode welding mode.

[0089] In combination Figure 16 , Figure 16 The structure schematic diagram of one embodiment of the fixed shell provided in the present application is shown in the figure. Specifically, the fixed shell 11 includes a side wall 111 and a bottom wall 112. The side wall 111 and the bottom wall 112 define a first accommodating cavity A1. The bottom wall 112 has a first through hole 1121 and a plurality of second through holes 1122 arranged around the first through hole 1121. The metal sheet includes a first flat sheet part 1421 and a first protruding part 1422. The first flat sheet part 1421 is arranged on the inner surface of the bottom wall 112 of the first accommodating cavity A1 and abuts against the metal spring. The first protruding part 1422 is arranged in the first through hole 1121 and exposed through the first through hole 1121, so as to abut against the electrode on the host 200. The outer surface of the bottom wall 112 also has a recessed part 1123. The plurality of second through holes 1122 are in communication with the recessed part 1123. The recessed part 1123 is arranged around the first through hole 1121. The metal ring includes a second flat sheet part 1321 in the shape of a ring and at least one second protruding part 1322 arranged on the edge of the second flat sheet part 1321. The second flat sheet part 1321 is embedded in the recessed part 1123. The second protruding part 1322 passes through the second through hole 1122 and is connected with the metal sleeve. The number of the second protruding part 1322 is the same as that of the second through hole 1122.

[0090] It can be understood that the metal sheet is at least partially arranged in the first accommodating cavity A1. One side of the first connecting part 132 abuts against the metal spring, and the other side abuts against the top pin 202. When the metal spring exerts a force on the metal sheet in the direction away from the metal spring, the bottom wall 112 of the fixed shell 11 limits the metal sheet. When the top pin 202 exerts a force on the metal sheet in the direction away from the top pin 202, the metal spring is compressed and exerts a reverse force on the metal sheet, thereby limiting the metal sheet and ensuring the position of the second conductive assembly 14 is fixed. In addition, the metal ring is connected with the metal sleeve through the second through hole 1122, and they limit each other, thereby ensuring the position of the first conductive assembly 13 is fixed.

[0091] Referring to Figures 17-19 , Figure 17A cross-sectional view of the second embodiment of the atomization assembly provided in the present application along line A-A; Figure 18 An exploded view of the structure of the second embodiment of the atomization assembly provided in the present application; Figure 19 A structural schematic view of an embodiment of the flexible fixing member provided in the present application. The atomization assembly 10 further comprises a flexible fixing member 15 arranged in the first accommodating cavity A1, which is used to further fix the atomization sheet 12. Since the atomization sheet 12 is used to atomize the aerosol generating substrate by ultrasonic atomization or mechanical vibration atomization, the atomization sheet 12 needs to be vibrated at a high frequency during the atomization process. In order to avoid affecting the working of the atomization sheet 12, the flexible fixing member 15 is made of a material with elasticity, such as silicone or rubber.

[0092] The flexible fixing member 15 has a second accommodating cavity A2; the first conductive member 131 is sleeved on the outer surface of the flexible fixing member 15, and the second conductive member 141 is arranged in the second accommodating cavity A2 to insulate the first conductive member 131 and the second conductive member 141 through the flexible fixing member 15, and the atomization sheet 12 and the second connecting member 142 are respectively located at opposite ends of the flexible fixing member 15, and the flexible fixing member 15 also plays a role in fixing the atomization sheet 12 and the second connecting member 142.

[0093] Specifically, in the atomization assembly 10 provided in the present application, the fixed shell 11, the flexible fixing member 15 and the first conductive member 131 are all hollow cylindrical bodies, the first conductive member 131 is sleeved on the outer surface of the flexible fixing member 15, the fixed shell 11 is sleeved on the outer surface of the first conductive member 131, the second connecting member 142 is located in the flexible connecting member, the atomization sheet 12 is circular and arranged at the first end of the flexible connecting member, the first connecting member 132 and the second connecting member 142 are arranged at the second end of the flexible connecting member, and the fixed shell 11, the atomization sheet 12, the first conductive assembly 13, the second conductive assembly 14 and the flexible fixing member 15 are coaxially arranged, thereby assembling to form the modular atomization assembly 10, which is convenient for installation and replacement of the atomization assembly 10 and is conducive to standardized and mechanized production.

[0094] In an embodiment, the flexible fixing member 15 comprises a first fixing part 151 and a second fixing part 152 arranged coaxially, both of which are hollow cylindrical and coaxially arranged, the first fixing part 151 is sleeved on the outside of the second fixing part 152, the atomization sheet 12 abuts against the first end of the first fixing part 151, the inner side wall of the first fixing part 151 is spaced from the outer side wall of the second fixing part 152, and the inner diameter of the second fixing part 152 is substantially the same as the maximum outer diameter of the second conductive member 141, thereby playing a role in fixing the second conductive member 141 to avoid deviation of the second conductive member 141 when the atomization sheet 12 is working.

[0095] In an embodiment, the side wall 111 of the fixed shell 11 has at least one notch 1111 arranged along the axial direction X, which can appropriately expand the port of the fixed shell 11 by external force to insert other components into the first accommodating cavity A1. In this embodiment, the notches 1111 are multiple and arranged circumferentially around the side wall 111. In addition, the outer surface of the first conductive member 131 has an outer flange 1312, and the inner surface of the side wall 111 has an inner flange 1112, which abuts above the outer flange 1312 when the first conductive member 131 is fixedly connected with the fixed shell 11, so as to fix the first conductive member 131 and other components in the first accommodating cavity A1. It can be understood that when the metal spring exerts a force on the metal sheet in a direction away from the metal spring, the bottom wall 112 of the fixed shell 11 limits the metal sheet, and when the metal spring exerts a force on the atomizing sheet 12 in a direction away from the flexible fixing member 15, the limiting portion 1311 on the first conductive member 131 limits the atomizing sheet 12. In order to further prevent the first conductive member 131 from moving away from the bottom wall 112 under force, the inner flange 1112 on the side wall 111 of the fixed shell 11 limits the first conductive member 131, thereby limiting the first conductive member 131 and other components in the first accommodating cavity A1.

[0096] In an embodiment, the outer side wall of the fixed shell 11 is provided with a third connecting structure 113, and the inner side wall of the mounting base 32 is provided with a fourth connecting structure 322. The fixed shell 11 and the mounting base 32 are fixedly connected through the third connecting structure 113 and the fourth connecting structure 322. The connecting mode of the third connecting structure 113 and the fourth connecting structure 322 can be snap connection or threaded connection. In this embodiment, the third connecting structure 113 is a limiting protrusion arranged along the axial direction X, and the fourth connecting structure 322 is a limiting groove arranged along the axial direction X. The limiting protrusion can be multiple and arranged circumferentially at intervals along the fixed shell 11. The limiting groove has the same number of limiting protrusions and is arranged correspondingly.

[0097] The material of the fixed shell 11 is made of non-conductive material, such as plastic or insulating ceramic, so as to avoid electric shock when the user accidentally touches the fixed shell 11.

[0098] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
