[0022] As shown in Figures 1-4 Fig. 1, the atomizer 100 includes a liquid storage tank 1, a connecting seat 2, an atomizing core 3 and an atomizing electrode 4. The liquid storage tank 1 is formed with a liquid storage cavity 10 for storing aerosol substrate and an air outlet passage 11. The connecting seat 2 is arranged in the liquid storage cavity 10 and is formed with a receiving space in communication with the liquid storage cavity 10 and the air outlet passage 11. The atomizing core 3 is arranged in the receiving space to form an atomizing cavity 30 in communication with the air outlet passage 11. The atomizing core 3 is used to absorb the aerosol substrate and generate aerosol in the atomizing cavity 30. The generated aerosol is discharged through the air outlet passage 11 for a user to smoke. The atomizing electrode 4 is mounted on the connecting seat and arranged on a side of the atomizing core 3 away from the atomizing cavity 30. The atomizing electrode 4 directly abuts against the atomizing core 3 to realize electrical connection between the atomizing electrode 4 and the atomizing core 3. The atomizer 100 directly abuts the atomizing electrode 4 against the atomizing core 3 to realize electrical connection between the atomizing electrode 4 and the atomizing core 3 during assembly. The atomizing core 3 does not need to be provided with a pin for soldering with the atomizing electrode 4, so that the atomizer 100 is simple in assembly, low in cost and capable of realizing automatic production.

[0023] The liquid storage tank 1 includes a liquid storage tank body 12 and a gas guide pipe 13. The liquid storage tank body 12 forms a liquid storage cavity 10. The gas guide pipe 13 forms a gas outlet passage 11 and is arranged in the liquid storage cavity 10. One end of the gas guide pipe 13 is sealingly connected to the liquid storage tank body 12, and the other end is sealingly connected to the connecting seat 2.

[0024] It can be understood that the gas guide pipe 13 can be integrally formed with the liquid storage tank body 12 or the connecting seat 2. In an example, the gas guide pipe 13 is integrally formed with the liquid storage tank body 12, and a second sealing ring 131 is arranged between the gas guide pipe 13 and the connecting seat 2. The gas guide pipe 13 is sealingly connected to the connecting seat 2 through the second sealing ring 131.

[0025] The connecting seat 2 is arranged in the liquid storage cavity 10 and forms an accommodation space. The accommodation space is in communication with the liquid storage cavity 10 and the gas outlet passage 11, respectively. Figure 1 Figure 2 As shown in FIGS. 1 and 2, the connecting seat 2 includes a base 21, a first sealing member 22, and a support 23. The first sealing member 22 is mounted on the base 21, and the support 23 is mounted on the first sealing member 22. The base 21, the first sealing member 22, and the support 23 form the accommodation space. The atomization core 3 is arranged in the accommodation space and is mounted between the base 21 and the first sealing member 22. The atomization core 3, the first sealing member 22, and the support 23 form an atomization cavity 30, which is located between the atomization core 3 and the gas outlet passage 11. The atomization electrode 4 is mounted on the base 21 and abuts against the atomization core 3 to achieve electrical connection.

[0026] The base 21 is provided with a first clamping portion 211, and the liquid storage tank body 12 is provided with a second clamping portion 121 matched with the first clamping portion 211. The base 21 is mounted on one end of the liquid storage tank body 12 through the matching of the first clamping portion 211 and the second clamping portion 121. One of the first clamping portion 211 and the second clamping portion 121 is a clasp, and the other is a clamping groove. Figure 2 In the embodiment shown in FIG. 3, the first clamping portion 211 is a clasp, and the second clamping portion 121 is a clamping groove. It can be understood that when the atomizer 100 is cylindrical, the base 21 can also be screwed on one end of the liquid storage tank body 12.

[0027] The atomization core 3 is arranged in the accommodation space to form the atomization cavity 30 in communication with the gas outlet passage 11. In an example, as shown in FIGS. 1 and 2, the atomization core 3 is arranged in the accommodation space to form the atomization cavity 30 in communication with the gas outlet passage 11. Figures 2-4 ​As shown, the atomization core 3 is arranged in the accommodation space and is mounted between the base 21 and the first sealing member 22, and the atomization core 3, the first sealing member 22 and the support 23 enclose the atomization cavity 30. The atomization core 3 comprises a liquid absorbing member 31 and a heating member 32. The liquid absorbing member 31 can be liquid absorbing cotton, porous ceramic, porous metal, porous glass or other porous structures capable of absorbing aerosol substrate. The heating member 32 is used to generate heat to atomize the aerosol substrate absorbed by the liquid absorbing member 31. The liquid absorbing member 31 comprises an atomization face 311 facing the atomization cavity 30 and opposite to the air outlet channel 11, and an electrode face 312 opposite to the atomization cavity 30. The heating member 32 comprises a heating member body 321 and an electrode contact point 322 electrically connected to the heating member body 321. The heating member body 321 is arranged on the atomization face 311, and the electrode contact point 322 is arranged on the electrode face 312. The atomization electrode 4 is in abutment and electrical connection with the electrode contact point 322. The atomization face 311 is arranged facing the atomization cavity 30 and opposite to the air outlet channel 11, i.e. the atomization face 311 faces the air outlet channel 11, so that the condensed liquid generated after the aerosol is condensed can be atomized again by the atomization face 311 after dropping due to gravity. The electrode face 312 is opposite to the atomization cavity 30, so that the electrode contact point 322 is directly in abutment and electrical connection with the atomization electrode 4, and the atomization electrode 4 can be electrically connected with the atomization core 3 during assembly of the atomizer 100, and the atomization core 3 does not need to be provided with a pin for soldering with the atomization electrode 4, so that the atomizer 100 is simple to assemble and low in cost, and automatic production can be realized.

[0028] The connecting seat 2 further forms an air inlet channel 24. The air inlet channel 24 comprises an air inlet 241 and an air outlet 242. The air outlet 242 is in communication with the atomization cavity 30, and the height of the air outlet 242 in the air outlet direction of the air outlet channel 11 is greater than the height of the atomization face 311 in the air outlet direction of the air outlet channel 11. Figure 2 As shown, the air inlet channel 24 comprises an air inlet section 243 and an air outlet section 244. The air inlet section 243 comprises the air inlet 241, and the air outlet section 244 comprises the air outlet 242 and is in communication with the air inlet section 243. The base 21 forms the air inlet section 243, and the extension direction of the air inlet section 243 is crosswise arranged with the extension direction of the air outlet section 244. The support 23 forms the air outlet section 244, and the extension direction of the air outlet section 244 is crosswise arranged with the extension direction of the air outlet channel 11. External air flows into the atomization cavity 30 through the air inlet 241, the air inlet section 243, the air outlet section 244 and the air outlet 242 in sequence. Moreover, the height of the air outlet 242 in the air outlet direction of the air outlet channel 11 (in the direction Z as shown) is greater than the height of the atomization face 311 in the air outlet direction of the air outlet channel 11, which can prevent the aerosol substrate that has not been atomized from flowing out of the air inlet channel 24, and can also prevent the condensed liquid generated after the aerosol is condensed from flowing out of the air inlet channel 24. Figure 2

[0029] ​The connecting seat 2 is further formed with a liquid inlet channel 25 communicating with the liquid storage cavity 10, and a liquid inlet gap is formed between the electrode surface 312 and the connecting seat 2, which communicates with the liquid inlet channel 25, so that the aerosol substrate enters the liquid inlet gap through the liquid inlet channel 25 and is absorbed by the electrode surface. For example, the liquid inlet gap is formed between the electrode surface 312 and the base 21. The liquid inlet channel 25 includes a liquid inlet section 251 communicating with the liquid storage cavity 10 and a liquid outlet section 252 communicating with the liquid inlet section 251 and the liquid inlet gap, respectively. The bracket 23 is formed with the liquid inlet section 251, and the extension direction of the liquid inlet section 251 is crosswise arranged with the extension direction of the liquid outlet section 252. The base 21 is formed with the liquid outlet section 252, and the extension direction of the liquid outlet section 252 is crosswise arranged with the extension direction of the gas outlet channel 11. The aerosol substrate is absorbed by the electrode surface 312 after sequentially flowing through the liquid inlet section 251, the liquid outlet section 252 and the liquid inlet gap, and is transmitted to the atomization surface 311, so that the liquid absorbing member 31 conducts the aerosol substrate from bottom to top, thereby preventing the unatomized aerosol substrate from being carried out by the airflow and being inhaled by the user, affecting the taste.

[0030] It can be understood that, as shown in Figures 1-2 The atomizer 100 can further include a liquid guiding member 5 arranged in the liquid inlet gap. The liquid guiding member 5 is used to absorb the aerosol substrate and transmit the absorbed aerosol substrate to the electrode surface 312 for atomization by the atomization surface 311. The liquid guiding member 5 can be partially located in the liquid outlet section 252, thereby further enhancing the liquid guiding effect.

[0031] It should be noted that in other embodiments, the side surface of the liquid absorbing member can also absorb the aerosol substrate, thereby improving the efficiency of the liquid absorbing member in transmitting the aerosol substrate.

[0032] The assembly process of the atomizer 100 is as follows:

[0033] S1, rivet and press the atomization electrode 4 to the base 21, and make the atomization electrode 4 and the base 21 in sealed connection.

[0034] S2, install the atomization core 3 to one end of the first sealing member 22, and then install the bracket 23 to the other end of the first sealing member 22, wherein the atomization surface 311 of the atomization core 3 faces the bracket 23, so that the atomization core 3, the first sealing member 22 and the bracket 23 form a surrounding atomization cavity 30.

[0035] S3, install the liquid guiding member 5 to the base 21, and then install the assembled first sealing member 22 to the base 21, wherein the electrode surface 312 of the atomization core 3 faces the base 21, so that the electrode contact point 322 and the atomization electrode 4 are in abutment and electrical connection.

[0036] S4, one end of the air guide pipe 13 is installed on the support 23 through the second sealing element 131, the base 21 is installed on the liquid storage bin 1, and the other end of the air guide pipe 13 is riveted and pressed on the liquid storage bin 1.

[0037] The application also provides an aerosol generating device, which comprises a main machine and the atomizer 100 as described above. The atomizer 100 can be detachably installed on the main machine by screwing, clamping or magnetic attraction, etc. The atomizer 100 can also be fixed on the main machine, which is not specifically limited herein.

[0038] The main machine comprises a main machine body and a power supply assembly. The power supply assembly is arranged in the main machine body and is electrically connected with the atomization electrode 4. For example, the power supply assembly comprises a battery, a circuit board and a main machine electrode. The circuit board is electrically connected with the battery and the main machine electrode respectively, and the main machine electrode is electrically connected with the atomization electrode 4. The battery can be a rechargeable battery or a non-rechargeable battery, which is not specifically limited herein.

[0039] Compared with the related art, the atomizer 100 provided by the application directly abuts the atomization electrode 4 with the atomization core 3, so that the atomization electrode 4 and the atomization core 3 are electrically connected during assembly, and the atomization core 3 does not need to be provided with a pin for soldering with the atomization electrode 4, so that the atomizer 100 is simple to assemble, low in cost and can be produced automatically. The atomization surface 311 of the atomizer 100 faces the atomization cavity 30, i.e. the atomization surface 311 faces the air outlet channel 11, so that the condensed liquid generated after the aerosol is condensed can be atomized again by the atomization surface 311 due to gravity. Moreover, the height of the air outlet 242 of the air inlet channel 24 in the air outlet direction of the air outlet channel 11 (the direction Z shown) is greater than the height of the atomization surface 311 in the air outlet direction of the air outlet channel 11, so that the aerosol matrix that is not atomized can be prevented from flowing out of the air inlet channel 24, and the condensed liquid generated after the aerosol is condensed can also be prevented from flowing out of the air inlet channel 24.
