[0039] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, the aerosol generating device involved in the embodiment of the present application includes: a shell assembly 100 and an atomization assembly 200.

[0040] Specifically, the shell assembly 100 includes an inner shell 110 and a suction nozzle 120, the suction nozzle 120 is connected to the downstream end of the inner shell 110 along the airflow direction, and the suction nozzle 120 is provided with an air outlet channel 121; the atomization assembly 200 is arranged in the inner shell 110, and the atomization assembly 200 is provided with an atomization channel 210, the upstream end of the air outlet channel 121 along the airflow direction is connected to the atomization channel 210, and the downstream end of the air outlet channel 121 along the airflow direction is connected to the outside; wherein, the suction nozzle 120 and the inner shell 110 are integrally formed.

[0041] It should be noted that the airflow direction refers to the flow direction of the aerosol-containing atomizing gas after the aerosol matrix is ​​atomized, that is, Figure 2 The direction that x points to.

[0042] In the above-mentioned aerosol generating device, the aerosol matrix is ​​usually accommodated in the atomizing assembly 200, and the aerosol matrix is ​​heated by the atomizing assembly 200 being powered on to generate heat, so that the aerosol matrix generates atomized aerosol gas. Since the upstream end of the gas outlet channel 121 along the airflow direction is connected to the atomizing channel 210, and the downstream end of the gas outlet channel 121 along the airflow direction is connected to the outside, the atomized gas can flow through the atomizing channel 210 and the gas outlet channel 121 in sequence, and finally flow out of the inhalation nozzle 120 through the gas outlet channel 121. For users to inhale, in this process, since the atomizer component 200 is arranged in the inner shell 110, and the mouthpiece 120 is integrally formed with the inner shell 110, the sealing performance of the atomizer component 200 in the inner shell 110 can be improved to reduce the possibility of leakage of the aerosol matrix in the atomizer component 200, and the possibility of leakage of the aerosol-containing atomized gas can also be reduced, further reducing the pollution to other structures in the aerosol generating device, reducing the waste of the aerosol matrix, and improving the user's experience.

[0043] Continue to refer to Figure 2 As shown in FIG4 , the nozzle 120 includes a nozzle shell 122 and a nozzle air outlet pipe 123 arranged in the nozzle shell 122. The aerosol generating device also includes a liquid suction component 300. In the airflow direction, the liquid suction component 300 is arranged between the atomization component 200 and the nozzle air outlet pipe 123, and the liquid suction component 300 is connected to the upstream end of the nozzle air outlet pipe 123. The liquid suction component 300 is provided with a vent hole 310, and the upstream end of the vent hole 310 is connected to the atomization channel 210, and the downstream end of the vent hole 310 is connected to the air outlet channel 121.

[0044] Specifically, in the above-mentioned embodiment, the liquid suction assembly 300 is sealedly connected to the upstream end of the suction nozzle air outlet pipe 123 .

[0045] Specifically, in the above-mentioned embodiment, the vent hole 310, the atomization channel 210 and the air outlet channel 121 are coaxially arranged to improve the smoothness of the user's inhalation process.

[0046] It can be understood that, in the direction of air flow, since the upstream end of the vent hole 310 is connected to the atomizing channel 210, and the downstream end of the vent hole 310 is connected to the air outlet channel 121, the atomized gas can flow through the atomizing channel 210, the vent hole 310 and the air outlet channel 121 in sequence, and finally flow out of the mouthpiece 120 through the air outlet channel 121 for the user to inhale. When the user stops inhaling the aerosol-containing atomized gas, the gas in the air outlet channel 121 will form condensed substances in the air outlet channel 121, and the condensed substances will mix with the liquid in the user's mouth in the air outlet channel 121, and may enter the air outlet channel 121 through the air outlet channel 121. In the atomization channel 210, since the liquid suction component 300 is arranged between the atomization component 200 and the nozzle air outlet pipe 123, and the liquid suction component 300 is connected to the upstream end of the nozzle air outlet pipe 123, the condensed material flowing out through the air outlet channel 121 and the liquid in the user's mouth can flow into the ventilation hole 310. In the process of the condensed material and the liquid in the user's mouth flowing through the ventilation hole 310, the condensed material flowing out of the air outlet channel 121 and the liquid in the user's mouth can be absorbed by the liquid suction component 300. In this way, the atomization channel 210 can be prevented from being contaminated, and the atomization component 200 can be further prevented from being contaminated.

[0047] Reference Figure 2 as well as Figure 5 As shown, the liquid absorption component 300 includes a first sealing component 320 and a liquid absorption component 330, both of which are arranged in the nozzle housing 122, and the first sealing component 320 is sealedly connected to the inner wall of the nozzle housing 122. In the airflow direction, the first sealing component 320 is sealedly connected to the upstream end of the nozzle air outlet pipe 123, and the side of the first sealing component 320 away from the nozzle air outlet pipe 123 is provided with a sealing groove 321 with an opening toward the atomization component 200, and the liquid absorption component 330 is fixedly arranged in the sealing groove 321; wherein, the vent hole 310 runs through both the first sealing component 320 and the liquid absorption component 330.

[0048] Specifically, in the above-mentioned embodiments, referring to Figure 7As shown, in the air flow direction, the first sealing component 320 is provided with a connecting hole 324 and a first sub-ventilation hole 325 connected to the connecting hole 324, the upstream end of the nozzle outlet pipe 123 is penetrated by the connecting hole 324, and is sealed and connected to the hole wall of the connecting hole 324, and the air outlet through hole is connected to the first sub-ventilation hole 325, and the liquid absorption component 330 is provided with a second sub-ventilation hole 331, and the two ends of the second sub-ventilation hole 331 are respectively connected to the first sub-ventilation hole 325 and the atomization channel 210, and the first sub-ventilation hole 325 and the second sub-ventilation hole 331 are both part of the ventilating hole 310, so that the first sealing component 320 and the nozzle outlet pipe 123 can be sealed and connected through the connecting hole 324, and the connection between the atomization channel 210 and the air outlet channel 121 can be achieved through the first sub-ventilation hole 325 and the second sub-ventilation hole 331.

[0049] Specifically, in the above-mentioned embodiments, referring to Figure 2 As shown, the outer wall of the first sealing member 320 corresponding to the side wall of the sealing groove 321 is sealedly connected to the inner wall of the nozzle housing 122 .

[0050] It can be understood that since the outer wall of the first sealing member 320 is sealed to the inner wall of the nozzle housing 122, and in the airflow direction, the first sealing member 320 is sealed to the upstream end of the nozzle air outlet pipe 123, the first sealing member 320 can be used to achieve a sealed connection between the liquid pipetting component 300 and the nozzle 120, and at the same time, a sealed connection between the liquid pipetting component 300 and the nozzle air outlet pipe 123 is achieved, so as to achieve the airtightness of the atomization component 200, and ensure that the aerosol-containing atomized gas can enter the air outlet channel 121 via the atomization channel 210, thereby improving the user's experience. At the same time, the condensed material flowing out of the air outlet channel 121 and the liquid in the user's mouth can be absorbed by the liquid pipetting member 330, so that the atomization channel 210 can be prevented from being contaminated, and the atomization component 200 can be further prevented from being contaminated. At the same time, since the vent hole 310 penetrates both the first sealing member 320 and the liquid absorbing member 330 , the atomization channel 210 and the air outlet channel 121 can be connected through the vent hole 310 .

[0051] Reference Figure 2 as well as Figure 5 As shown, the liquid absorption component 300 also includes a second seal 340, which covers the upstream end of the liquid absorption component 330 along the air flow direction and is sealed with the edge of the opening of the sealing groove 321; wherein the vent hole 310 simultaneously runs through the first seal 320, the second seal 340 and the liquid absorption component 330.

[0052] Specifically, in the above-mentioned embodiments, referring to Figure 5 as well as Figure 6As shown, in the airflow direction, the second sealing member 340 is provided with a third sub-ventilation hole 343, and the two ends of the third sub-ventilation hole 343 are respectively connected to the second sub-ventilation hole 331 and the atomization channel 210, and the first sub-ventilation hole 325, the second sub-ventilation hole 331 and the third sub-ventilation hole 343 are connected in sequence to form the ventilation hole 310, so as to realize the connection between the atomization channel 210 and the air outlet channel 121; wherein, in the airflow direction, the aperture of the downstream end of the third sub-ventilation hole 343 is less than or equal to the aperture of the second sub-ventilation hole 331, so as to realize the covering of the liquid absorption member 330 by the second sealing member 340, and the aperture of the upstream end of the third sub-ventilation hole 343 is greater than or equal to the aperture of the atomization channel 210, so as to ensure that the atomized gas in the atomization channel 210 can enter the third sub-ventilation hole 343.

[0053] It can be understood that since the second sealing member 340 is covered on the upstream end of the liquid absorbing member 330 along the airflow direction and is sealed with the edge of the opening of the sealing groove 321, the second sealing member 340 can cover the upstream end of the liquid absorbing member 330 along the airflow direction to isolate the liquid absorbing member 330 from the atomization assembly 200, thereby preventing the condensed material in the liquid absorbing member 330 and the liquid in the user's mouth from flowing into the atomization channel 210 from the upstream end of the liquid absorbing member 330, further preventing the atomization channel 210 from being contaminated, and preventing the atomization assembly 200 from being contaminated. At the same time, since the vent hole 310 simultaneously runs through the first sealing member 320, the second sealing member 340 and the liquid absorbing member 330, the connection between the atomization channel 210 and the air outlet channel 121 can be achieved through the vent hole 310.

[0054] Reference Figure 5 as well as Figure 6 As shown, there is a limiting gap 323 between the liquid absorbing member 330 and the side wall of the sealing groove 321, and the second sealing member 340 includes a sealing portion 341 and a fourth limiting portion 342 connected to the sealing portion 341. In the airflow direction, the edge of the downstream end of the sealing portion 341 is sealed with the edge of the opening of the sealing groove 321, and the fourth limiting portion 342 protrudes from the side of the sealing portion 341 close to the first sealing member 320, and the fourth limiting portion 342 is penetrated through the limiting gap 323 and abuts against the side wall of the sealing groove 321 and the liquid absorbing member 330.

[0055] Specifically, in the above-mentioned embodiment, the liquid absorbing portion covers the upstream end of the liquid absorbing member 330 along the airflow direction.

[0056] It can be understood that, in the airflow direction, since the edge of the downstream end of the sealing portion 341 is sealed and connected to the edge of the opening of the sealing groove 321, the sealing portion 341 can be used to achieve a sealed connection between the second sealing member 340 and the first sealing member 320 to close the opening of the sealing groove 321. In this way, the sealing portion 341 can be used to isolate the liquid absorbing member 330 from the atomizing assembly 200, thereby preventing the condensed material in the liquid absorbing member 330 and the liquid in the user's mouth from flowing into the atomizing channel from the upstream end of the liquid absorbing member 330. 210, and at the same time, since the fourth limiting portion 342 passes through the limiting gap 323 and abuts against the side wall of the sealing groove 321 and the liquid absorbing member 330, the position of the liquid absorbing member 330 in the sealing groove 321 can be limited and fixed by the fourth limiting portion 342 to prevent the liquid absorbing member 330 from moving in the sealing groove 321 in a direction perpendicular to the air flow direction, thereby ensuring the connectivity between the upstream and downstream of the vent 310 and ensuring that the sealing portion 341 can cover the upstream end of the liquid absorbing member 330 along the air flow direction.

[0057] Specifically, in the above-mentioned embodiment, the upstream end of the sealing portion 341 abuts against the atomizing assembly 200 .

[0058] Reference Figure 2 as well as Figure 4 As shown, the nozzle housing 122 is provided with a fifth limiting portion 1223 protruding from the inner wall thereof, the downstream end of the first sealing member 320 abuts against the fifth limiting portion 1223 , and the upstream end of the second sealing member 340 abuts against the atomizing assembly 200 .

[0059] It can be understood that since the downstream end of the first seal 320 abuts against the fifth limiting portion 1223 and the upstream end of the second seal 340 abuts against the atomizer assembly 200, the liquid absorption assembly 300 can be fixed between the nozzle air outlet pipe 123 and the atomizer assembly 200 to prevent the liquid absorption assembly 300 from moving along the air flow direction, thereby improving the structural stability of the above-mentioned aerosol generating device. At the same time, it is also possible to confirm whether the liquid absorption assembly 300 is installed in place through the fifth limiting portion 1223.

[0060] Reference Figure 1 as well as Figure 8 As shown, the shell assembly 100 also includes an outer shell 130, which is provided with a first accommodating cavity 131 and a first opening 132 connected to the first accommodating cavity 131. The inner shell 110 is fixedly disposed in the first accommodating cavity 131, and the suction nozzle 120 is at least partially exposed outside the first accommodating cavity 131 through the first opening 132.

[0061] It can be understood that the inner shell 110 and the nozzle 120 can be fixed by the outer shell 130. At the same time, since the inner shell 110 is fixedly disposed in the first accommodating cavity 131, the inner shell 110 can be protected by the first accommodating cavity 131 to further protect the atomizer assembly 200. Since the nozzle 120 is at least partially exposed outside the first accommodating cavity 131 through the first opening 132, the user's oral cavity can contact the part of the nozzle 120 exposed outside the first accommodating cavity 131, and the aerosol-containing atomized gas in the above-mentioned aerosol generating device can be inhaled through the part of the nozzle 120.

[0062] Continue to refer to Figure 4 as well as Fig. 9 As shown, the inner shell 110 is provided with a second opening 114 at the upstream end along the airflow direction, and the edge of the second opening 114 is provided with a guide portion 115 and a third limiting portion 116. The shell assembly 100 also includes an end cover 140, and the end cover 140 has a connecting portion and a sliding portion 141 and a clamping portion 142 connected to the connecting portion. The connecting portion is sealed and connected to the edge of the second opening 114, the sliding portion 141 is slidably connected to the guide portion 115, and the clamping portion 142 is fixedly connected to the third limiting portion 116.

[0063] Specifically, refer to Fig. 9 As shown, in the above-mentioned embodiment, the clamping portion 142 is a clamp, the third limiting portion 116 is a limiting groove, the sliding portion 141 is a sliding groove, and the guide portion 115 is a guide plate. Of course, in other embodiments, the clamping portion 142 can also be a clamping groove, the third limiting portion 116 can be a limiting clamp, the sliding portion 141 can be a sliding plate, and the guide portion 115 can be a guide groove.

[0064] It is understandable that when the sliding portion 141 slides to a preset position along the guide portion 115 , the engaging portion 142 engages with the third limiting portion 116 to limit the relative movement between the end cover 140 and the inner shell 110 , thereby facilitating assembly between the end cover 140 and the inner shell 110 .

[0065] Specifically, in the above-mentioned embodiment, during the assembly of the atomizer device, the first sealing member 320 is disposed in the nozzle housing 122 through the second opening 114 and is abutted against the fourth limiting portion 342, the liquid suction member 330 is disposed in the sealing groove 321 through the second opening 114, the second sealing member 340 enters the nozzle housing 122 through the second opening 114 and is abutted against the first sealing member 320, the atomizer assembly 200 enters the inner housing 110 through the second opening 114 and is abutted against the first sealing member 320, and thus, the assembly of the above-mentioned atomizer device can be achieved through the second opening 114, and during the assembly process, the fixation of the liquid suction assembly 300 and the atomizer assembly 200 can be achieved by the abutment between any two adjacent structures.

[0066] Reference Figure 2 , Figure 3 as well as Fig.10 As shown, the aerosol generating device also includes an airflow detection component 400, and a receiving groove 124 with an opening connected to the first receiving cavity 131 is provided on the outer wall of the nozzle shell 122, and the airflow detection component 400 is fixedly arranged in the receiving groove 124, and the nozzle shell 122 is provided with an air outlet 1221 connected to the outside, and the nozzle shell 122 is also provided with a first airflow detection channel 1222 isolated from the air outlet channel 121, and a first air inlet 1241 is provided at the bottom of the receiving groove 124, and the first air inlet 1241 and the air outlet 1221 are both connected to the first airflow detection channel 1222; wherein, the air outlet 1221 and the first air inlet 1241 are both spaced apart from the air outlet channel 121.

[0067] Specifically, in the above-mentioned embodiment, the airflow detection assembly 400 is sealed and connected to the side wall of the receiving groove 124, and the opening of the receiving groove 124 is opened in a direction perpendicular to the airflow direction.

[0068] Specifically, in the above-mentioned embodiment, the above-mentioned aerosol generating device also includes a circuit board PCBA, and an installation gap is defined between the power supply component 500, the inner shell 110 and the outer shell 130. The circuit board is located in the installation gap, and the circuit board is electrically connected to the power supply component 500 and the airflow detection component 400 respectively. The power supply component 500 and the atomization component 200 are respectively located on opposite sides of the same surface of the circuit board, and the length direction of the circuit board is parallel to the airflow direction. The power supply component 500 and the atomization component 200 are respectively located on both sides of the width direction of the circuit board (such as Figure 4 The airflow detection component 400 includes a microphone airflow sensor for detecting whether air has entered the aerosol generating device. The microphone airflow sensor and the atomizing component 200 are electrically connected to the circuit board. When the microphone airflow sensor detects that air has entered the aerosol generating device (i.e., air is inhaled into the aerosol generating device through the user's suction), the microphone airflow sensor can send an airflow signal to the circuit board, so that the circuit board controls the atomizing component 200 to be powered on and heated, so as to atomize the aerosol matrix through the atomizing component 200, thereby realizing the user's inhalation of the aerosol.

[0069] It should be noted that in a traditional aerosol generating device, the airflow detection component 400 is usually arranged upstream of the airflow direction, and the airflow entering the aerosol generating device will flow through the airflow detection component 400 and the atomization component 200 in sequence. In this way, when the user stops inhaling the aerosol-containing atomized gas, the aerosol matrix or condensed substance in the atomization component 200 will gradually flow to the airflow detection component 400 due to the action of gravity, which will cause contamination to the airflow detection component 400.

[0070] It is understandable that, since the receiving groove 124 is provided on the nozzle housing 122, the airflow detection assembly 400 is fixedly arranged in the receiving groove 124, and therefore, the airflow detection assembly 400 can be arranged downstream near the airflow direction, so that the aerosol matrix or condensed material in the atomization assembly 200 can be prevented from polluting the airflow detection assembly 400, and the service life of the airflow detection assembly 400 can be extended. In this process, air can flow to the airflow detection assembly 400 through the opening of the receiving groove 124, and flow through the first air inlet 1241, the first airflow detection channel 1222 and the air outlet 1221 in sequence, so as to achieve the purpose of air flowing through the airflow detection assembly 400. At the same time, since the air outlet 1221 and the first air inlet 1241 are spaced from the air outlet channel 121, therefore, the atomized gas containing the aerosol matrix will not flow through the airflow detection assembly 400, so as to prevent the aerosol matrix or condensed material in the atomization assembly 200 from polluting the airflow detection assembly 400.

[0071] Specifically, in the above-mentioned embodiments, referring to Figure 4As shown, the end cover 140 is provided with an air inlet channel 143 extending along the air flow direction, and the air inlet channel 143 is isolated from the first accommodating chamber 131, and the upstream end of the air inlet channel 143 in the air flow direction is connected to the outside, and the downstream end of the air inlet channel 143 is connected to the atomizing channel 210, so that air flows through the atomizing channel 210, and the upstream end of the outer shell 130 in the air flow direction is provided with a second air inlet port 134 and a third air inlet port 135 arranged at intervals, and the second air inlet port 134 and the third air inlet port 135 are both connected to the outside, the second air inlet port 134 is connected to the air inlet channel 143, and the third air inlet port 135 is connected to the first accommodating chamber 131, so that when the user inhales, the air will pass through the second air inlet port 1 34 enters into the air inlet channel 143, and then enters into the atomization channel 210. At the same time, the air also enters into the first accommodating chamber 131 through the third air inlet port 135, and then flows through the accommodating groove 124, and flows to the first air inlet port 1241 through the airflow detection component 400 in the accommodating groove 124. In this way, a second airflow detection channel 136 can be formed between the third air inlet port 135 and the accommodating groove 124. The second airflow detection channel 136 is connected to the first airflow detection channel 1222 to form an airflow detection channel. In this way, the atomization channel 210 and the airflow detection channel can be isolated to prevent the aerosol matrix or condensed material in the atomization component 200 from contaminating the airflow detection component 400.

[0072] Reference Figure 2 as well as Figure 4 As shown, the first sealing member 320 is spaced apart from the inner wall of the downstream end of the nozzle housing 122 along the airflow direction, the nozzle housing 122 and the nozzle air outlet pipe 123 define a cavity 125, and the flow path of the first airflow detection channel 1222 passes through the cavity 125. The inner housing 110 is provided with a second accommodating cavity 111, and the atomizing assembly 200 is arranged in the second accommodating cavity 111, and the second accommodating cavity 111, the atomizing channel 210 and the air outlet channel 121 are all isolated from the cavity 125. In the airflow direction, the liquid suction assembly 300 is arranged between the atomizing assembly 200 and the nozzle air outlet pipe 123 to isolate the cavity 125 and the second accommodating cavity 111. The downstream end of the liquid suction assembly 300 along the airflow direction is spaced apart from the inner wall of the nozzle housing 122 to connect the first air inlet 1241 with the cavity 125, and the flow path of the first airflow detection channel passes through the cavity 125.

[0073] It can be understood that the first sealing member 320 can be used to isolate the second accommodating chamber 111, the atomization channel 210 and the air outlet channel 121 from the cavity 125, thereby ensuring that the gas in the atomization channel 210 can only flow through the air outlet channel 121, and preventing the atomized gas from entering the cavity 125, so as to improve the utilization rate of the aerosol matrix and improve the user's experience. At the same time, it can prevent the atomized gas from entering the first airflow detection channel 1222 and causing contamination to the airflow detection component 400.

[0074] Reference Figure 6 as well as Figure 7 As shown, the downstream end of the liquid suction component 300 along the airflow direction is spaced apart from the inner wall of the nozzle housing 122 to connect the first air inlet 1241 with the cavity 125, and the flow path of the first airflow detection channel passes through the cavity 125. Specifically, the downstream end of the first sealing member 320 in the liquid suction component 300 along the airflow direction is provided with a groove 322, the groove 322 is arranged close to the air inlet, and one end of the groove 322 is communicated with the air inlet, and the other end of the groove 322 is communicated with the first airflow detection channel 1222, so as to realize the communication between the first air inlet 1241 and the cavity 125.

[0075] Specifically, in the above-mentioned embodiments, referring to Figure 2 As shown, the receiving groove 124 is opened near the upstream end of the nozzle shell 122. Therefore, in the airflow direction, the receiving groove 124 and the liquid suction component 300 are located at the same position. Since the first sealing member 320 is sealed and connected to the inner wall of the nozzle shell 122, the groove 322 can facilitate the connection between the first air inlet 1241 and the first airflow detection channel 1222, thereby improving the smoothness of the air circulation in the airflow detection channel.

[0076] It is understandable that the first air inlet 1241 and the first airflow detection channel 1222 can be connected via the groove 322 to ensure the circulation of air in the airflow detection channel.

[0077] Reference Figure 2 , Figure 4 , Figure 8 as well as Fig.10 As shown, the aerosol generating device further includes a power supply component 500 disposed in the first accommodating chamber 131, the axial direction of the power supply component 500 is parallel to the airflow direction, and the power supply component 500 is connected to the airflow detection component 400, wherein the axial direction of the power supply component 500 is the direction where the electrode is located, that is, Figure 2The outer shell 130 has a first limiting portion 133 connected to the cavity wall of the first accommodating cavity 131, and the first limiting portion 133 protrudes from the cavity wall of the first accommodating cavity 131. The inner shell 110 includes a shell portion 112 and a second limiting portion 113 connected to the outer wall of the shell portion 112. The atomizer assembly 200 is arranged in the shell portion 112. In the airflow direction, the second limiting portion 113 is arranged between the upstream end and the downstream end of the shell portion 112, and the second limiting portion 113 is spaced from the first limiting portion 133. The two ends of the power supply assembly 500 are respectively against the first limiting portion 133 and the second limiting portion 113.

[0078] It can be understood that the power supply assembly 500 can be fixed between the first limiting portion 133 and the second limiting portion 113 by the first limiting portion 133 and the second limiting portion 113. At the same time, in the airflow direction, since the second limiting portion 113 is arranged between the upstream end and the downstream end of the shell portion 112, and the second limiting portion 113 and the first limiting portion 133 are spaced apart, the two ends of the power supply assembly 500 are respectively against the first limiting portion 133 and the second limiting portion 113. Therefore, the atomization assembly 200 and the power supply assembly 500 can be arranged in a direction perpendicular to the airflow direction. In this way, when air enters the above-mentioned aerosol generating device, the power supply assembly 500 can be prevented from interfering with the path of air entering the atomization channel 210, so that the air can directly enter the atomization channel 210, thereby improving the atomization efficiency of the above-mentioned aerosol generating device. At the same time, it can also prevent the aerosol matrix or condensed matter in the atomization assembly 200 from contaminating the power supply assembly 500.
