[0031] The present application is described in detail below with reference to the accompanying drawings and embodiments.

Figure 3 yes Figure 2 Schematic diagram of the gas-liquid flow of the atomization assembly shown.

[0033] The present application provides an electronic atomization device 100, which can be used for atomization of an aerosol-generating substrate. The electronic atomization device 100 can be specifically applied to different fields, such as medical treatment, beauty, leisure smoking, etc. In this embodiment, the electronic atomization device 100 is used for leisure smoking.

One end of the housing assembly 11 is an open section, and the bottom cover 15 is detachably connected to the open end of the housing assembly 11, and the bottom cover 15 blocks the open end of the housing assembly 11.

[0035] Among them, the battery cell assembly 13 is connected to the battery cell installation assembly 14 in a plug-in manner. It can be understood that compared with the prior art, the battery cell assembly 13 is connected to other structural parts by welding the wire body, and the wire body needs to be cut for disassembly, which may cause the battery cell assembly 13 to short-circuit, heat up, catch fire, and other problems; in the embodiment of the present application, the battery cell assembly 13 and the battery cell installation assembly 14 are connected in a plug-in manner, which is convenient for the battery cell assembly 13 to be disassembled from the battery cell installation assembly 14, and will not damage the structure of the battery cell assembly 13, avoiding the problems of short-circuit, heat up, and catch fire during the disassembly of the battery cell assembly 13, improving the safety performance, and facilitating the recycling and replacement of the battery cell assembly 13; at the same time, it makes it unnecessary to weld the wire body during the assembly process, and the installation process is simple, which is conducive to saving man-hours, improving assembly efficiency, and facilitating the realization of automated assembly.

[0036] The housing assembly 11 is formed with a first installation cavity 111, and the atomizer assembly 12 is disposed in the first installation cavity 111. The housing 11 is also formed with an atomizer channel 112. One end of the atomizer channel 112 serves as a suction port 1121, through which the user inhales aerosol; the other end of the atomizer channel 112 is embedded in the atomizer assembly 12, and the atomizer channel 112 is in fluid communication with the atomizer assembly 12. The housing assembly 11 and the atomizer assembly 12 define a liquid storage cavity 10.

[0037] The atomizer assembly 12 includes a first atomizer seat 121, a second atomizer seat 122, an atomizer core 123 and an atomizer ejector pin 124. In the present embodiment, the atomizing surface of the atomizer core 123 is substantially parallel to the axial direction of the atomizer channel 112, i.e., lateral atomization; the structure of the atomizer assembly 12 is introduced taking lateral atomization as an example. In other embodiments, the atomizing surface of the atomizer core 123 may be away from the suction port 1121 (atomization downwards), or the atomizing surface of the atomizer core 123 may be toward the suction port (atomization upwards), and the structures of the first atomizer seat 121 and the second atomizer seat 122 may be changed accordingly.

[0038] The first atomizer seat 121 is detachably connected to the second atomizer seat 122. The first atomizer seat 121 is located on a side of the second atomizer seat 122 away from the bottom cover 15; in other words, the first atomizer seat 121 is located on a side of the second atomizer seat 122 close to the suction port 1121. The atomizer core 123 is installed on the first atomizer seat 121. A lower liquid hole 1211 is provided on the first atomizer seat 121, and the lower liquid hole 1211 is in fluid communication with the atomizer core 123. The aerosol-generating matrix in the liquid storage chamber 10 flows to the atomizer core 123 through the lower liquid hole 1211, and is heated and atomized by the atomizer core 123 to generate an aerosol.

[0039] The first atomizing seat 121 cooperates with the second atomizing seat 122 to form a cavity 120. The end of the atomizing channel 112 is embedded in the first atomizing seat 121, and the atomizing channel 112 is connected to the cavity 120. The atomizing surface of the atomizing core 123 is exposed to the cavity 120, and the aerosol overflowing from the atomizing surface of the atomizing core 123 is released into the cavity 120. The second atomizing seat 122 is provided with an air inlet 1221, and the air inlet 1221 is connected to the cavity 120. The gas entering from the air inlet 1221 flows through the atomizing surface of the atomizing core 123, carrying the aerosol generated by the atomizing core 123 to flow to the atomizing channel 112.

[0040] The atomizing core 123 includes a liquid guiding member (not shown) and a heating element (not shown). The liquid guiding member includes a liquid absorption surface and an atomizing surface that are relatively arranged. The liquid absorption surface is fluidically connected to the lower liquid hole 1211, and the atomizing surface is fluidically connected to the cavity 120. The heating element is arranged on the atomizing surface. The liquid guiding member has a capillary force, which guides the aerosol generating matrix from the liquid absorption surface to the atomizing surface to maintain sufficient liquid supply to the heating element. The heating element heats the atomized aerosol generating matrix to produce an aerosol. Optionally, the liquid guiding member is a porous ceramic, and the disordered pores generated by the porous ceramic during the preparation process have a capillary force. Optionally, the heating element is a heating film, which can be formed on the atomizing surface by vapor deposition or sputtering.

[0041] The atomizing assembly 12 includes two atomizing ejector pins 124, which are fixed to the second atomizing seat 122. In this embodiment, the atomizing surface of the atomizing core 123 is substantially parallel to the axial direction of the atomizing channel 112, and the side surfaces of the two atomizing ejector pins 124 are respectively in contact with the positive electrode and the negative electrode of the heating film of the atomizing core 123, so as to electrically connect the atomizing ejector pins 124 to the atomizing core 123.

[0042] The housing assembly 11 is also formed with a second installation cavity 114, and the battery cell assembly 13 and the battery cell installation assembly 14 are placed in the second installation cavity 114. The electronic atomization device 100 presents a flat appearance, and has a width dimension and a thickness dimension perpendicular to its length direction, wherein the thickness dimension is smaller than the width dimension. The first installation cavity 111 and the second installation cavity 114 are arranged side by side along the width direction of the electronic atomization device, and such an arrangement provides ample installation space for the atomization assembly 12, the battery cell assembly 13 and the battery cell installation assembly 14, respectively. The atomization assembly 12 and the battery cell assembly 13 and the battery cell installation assembly 14 are respectively located in two chambers, so as to prevent the aerosol generated by the atomization of the atomization assembly 12 from entering the second installation cavity 114, and causing damage to the battery cell 131 of the battery cell assembly 13 and the adapter plate 143 of the battery cell installation assembly 14 in the second installation cavity 114, and also reduce the pollution of the aerosol, and ensure that the aerosol is more pure.

[0045] The battery cell mounting assembly 14 includes two elastic clips 141, and the two elastic clips 141 are arranged in a one-to-one correspondence with the two electrode pins 132. The elastic clips 141 clamp the electrode pins 132 to achieve a plug-in connection between the battery cell assembly 13 and the battery cell mounting assembly 14. It should be noted that the present application is not limited to the use of the elastic clips 141 to clamp the electrode pins 132 to achieve a plug-in connection between the battery cell assembly 13 and the battery cell mounting assembly 14; for example, the battery cell mounting assembly 14 may be provided with an insertion hole, and elastic shrink blocks may be provided at intervals on the hole wall, so that after the electrode pins 132 of the battery cell assembly 13 are inserted into the insertion hole, the elastic shrink blocks clamp the electrode pins 132 to achieve a plug-in connection between the battery cell assembly 13 and the battery cell mounting assembly 14. That is to say, the battery cell mounting assembly 14 includes an elastic clamping portion, which clamps the electrode pin 132 to achieve a plug-in connection between the battery cell assembly 13 and the battery cell mounting assembly 14, wherein the elastic clamping portion can be an elastic clip 141 or an elastic shrink block.

By providing the groove 154 at a position adjacent to the connection between the bottom cover 15 and the shell assembly 11, and making the groove 154 at least partially expose the shell assembly 11, a fulcrum is provided for the disassembly of the bottom cover 15 and the shell assembly 11, and the disassembly is facilitated. Optionally, the bonding strength of the connection between the bottom cover 15 and the shell assembly 11 is relatively strong, and the bottom cover 15 and the shell assembly 11 can be disassembled with the help of tools to ensure the normal function of the electronic atomization device.

[0063] In one embodiment, the bottom cover 15 is magnetically connected to the housing assembly 11 .

The slot 154 and the hook 155 are arranged at intervals, and the slot 154 is arranged adjacent to the hook 155. The shell assembly 11 blocks part of the slot 154, and the connection between the end face of the shell assembly 11 away from the suction port 1121 and the inner surface of the shell assembly 11 is a fourth inclined surface L, so that the tool can be inserted into the slot 154 to assist in the disassembly of the bottom cover 15 and the shell assembly 11, thereby realizing the recycling and replacement of the battery cell assembly 13.

[0065] In one embodiment, see Fig.11 , Fig.11 yes Figure 1 The exploded structural diagram of the housing assembly shown in the figure shows that the housing assembly 11 includes a housing 115 and a battery tube 116. The battery tube 116 is sleeved on the outside of the housing 115. The battery tube 116 is detachably connected to the bottom cover 15. Fig.11 Combination Figure 1 The housing 115 includes a first sub-shell 115a and a second sub-shell 115b, and the first sub-shell 115a and the second sub-shell 115b are arranged side by side; optionally, the first sub-shell 115a and the second sub-shell 115b are integrally formed.

[0066] The first sub-shell 115a forms the atomization channel 112 and the first installation cavity 111, and the atomization assembly 12 is placed in the first installation cavity 111 and blocks the open end of the first installation cavity 111; the first sub-shell 115a cooperates with the atomization assembly 12 placed in the first installation cavity 111 to form the liquid storage cavity 10. The outer surface of the second sub-shell 115b and the outer surface of the end of the first sub-shell 115a away from the bottom cover 15 are smoothly transitioned, and the distance between the end of the second sub-shell 115b close to the bottom cover 15 and the bottom cover 15 is greater than the distance between the end of the first sub-shell 115a close to the bottom cover 15 and the bottom cover 15. The outer surface of the part of the first sub-shell 115a close to the second sub-shell 115b cooperates with the inner surface of the second sub-shell 115b and the inner surface of the battery tube 116 to form the second installation cavity 114. The cell installation assembly 14 and the cell assembly 13 are arranged in the second installation cavity 114; wherein, the cell installation assembly 14 is arranged in the second sub-shell 115b, and the cell installation assembly 14 and the second sub-shell 115b are interference-fitted.

[0067] Specifically, the cell mounting assembly 14 is loaded from the open end of the second sub-shell 115b and fixed to the end of the second sub-shell 115b away from the bottom cover 15, and the orthographic projection of the cell mounting assembly 14 on the cell assembly 13 covers the cell assembly 13. By setting the distance between the end of the second sub-shell 115b close to the bottom cover 15 and the bottom cover 15 to be greater than the distance between the end of the first sub-shell 115a close to the bottom cover 15 and the bottom cover 15, the assembly distance of the cell mounting assembly 14 loaded from the open end of the second sub-shell 115b is shortened, so that the cell mounting assembly 14 is easily fixed to the end of the second sub-shell 115b away from the bottom cover 15.

[0068] By configuring the shell assembly 11 as a detachable structure in which the outer shell 115 and the battery tube 116 are described above, the volume of the battery cell assembly 13 is larger, which facilitates the assembly and disassembly of the battery cell assembly 13 .

[0069] Continue reading Figure 1 The electronic atomization device further includes a sealing cover 16, which is disposed in the housing assembly 11. The sealing cover 16 is located on the same side of the atomization assembly 12 and the battery cell assembly 13, away from the side of the suction port 1121. The sealing cover 16 presses against the battery cell assembly 13 to ensure the stability of the connection between the battery cell assembly 13 and the battery cell mounting assembly 14. Optionally, the sealing cover 16 is made of silicone.
