The liquid absorption component is connected to the upstream end of the nozzle outlet pipe. The liquid absorption component has a vent hole. The upstream end of the vent hole communicates with the atomizing channel, and the downstream end of the vent hole communicates with the outlet channel.

[0007] According to the aerosol generating device of this application embodiment, the liquid absorption component includes a first sealing member and a liquid absorption member. Both the first sealing member and the liquid absorption member are disposed inside the nozzle housing, and the first sealing member is sealed to the inner wall of the nozzle housing.

The side of the first sealing member away from the nozzle outlet pipe is provided with a sealing groove with an opening facing the atomizing component, and the liquid absorption member is fixedly disposed in the sealing groove. The vent hole passes through both the first sealing member and the liquid absorption member.

[0008] According to the aerosol generating device of the present application embodiment, the liquid absorption component further includes a second sealing member, which covers the upstream end of the liquid absorption member along the airflow direction and is sealed to the edge of the opening of the sealing groove; wherein, the vent hole simultaneously penetrates the first sealing member, the second sealing member, and the liquid absorption member.

[0009] According to the aerosol generating device of the present application embodiment, the housing assembly further includes an outer shell, the outer shell having a first receiving cavity and a first opening communicating with the first receiving cavity, the inner shell being fixedly disposed in the first receiving cavity, and the nozzle being at least partially exposed outside the first receiving cavity through the first opening.

[0010] According to an embodiment of this application, the aerosol generating device further includes an airflow detection component. The outer wall of the nozzle is provided with a receiving groove with an opening communicating with the first receiving cavity. The airflow detection component is fixedly disposed in the receiving groove. The nozzle is provided with an air outlet communicating with the outside, and the nozzle is also provided with a first airflow detection channel isolated from the air outlet channel. The bottom of the receiving groove is provided with a first air inlet. The first air inlet and the air outlet are both communicating with the first airflow detection channel. The air outlet and the first air inlet are both spaced apart from the air outlet channel.

[0011] According to the aerosol generating device of this application embodiment, the liquid suction component is spaced apart from the inner wall of the suction nozzle housing at its downstream end along the airflow direction to connect the first air inlet and the cavity, and the flow path of the first airflow detection channel passes through the cavity.

[0015] The aerosol generating device of this application has the following advantages:

[0016] In the aforementioned aerosol generator, the aerosol matrix is ​​housed in an atomizing component. The atomizing component is electrically heated to generate atomized aerosol. Since the upstream end of the outlet channel is connected to the atomizing channel along the airflow direction, and the downstream end is connected to the outside, the atomized gas flows sequentially through both the atomizing channel and the outlet channel, ultimately exiting through the outlet channel and exiting through the mouthpiece for the user to inhale. During this process, because the atomizing component is housed within the inner shell, and the mouthpiece is integrally formed with the inner shell, the sealing performance of the atomizing component within the inner shell is improved, reducing the possibility of aerosol matrix leakage. Simultaneously, the possibility of aerosol-containing atomized gas leakage is also reduced, further minimizing contamination of other structures within the aerosol generator, reducing aerosol matrix waste, and improving the user experience.

[0039] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, the aerosol generating device involved in the embodiments of this application includes: a housing assembly 100 and an atomizing assembly 200.

[0040] Specifically, the housing assembly 100 includes an inner housing 110 and a nozzle 120. The nozzle 120 is connected to the downstream end of the inner housing 110 along the airflow direction, and the nozzle 120 is provided with an air outlet channel 121. The atomizing assembly 200 is disposed inside the inner housing 110 and is provided with an atomizing channel 210. The upstream end of the air outlet channel 121 along the airflow direction is connected to the atomizing channel 210, and the downstream end of the air outlet channel 121 along the airflow direction is connected to the outside. The nozzle 120 and the inner housing 110 are integrally formed.

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

[0042] In the aforementioned aerosol generating device, the aerosol matrix is ​​typically housed in the atomizing component 200. The atomizing component 200 is electrically heated to generate atomized aerosol gas. Since the upstream end of the outlet channel 121 along the airflow direction is connected to the atomizing channel 210, and the downstream end of the outlet channel 121 along the airflow direction is connected to the outside, the atomized gas can flow sequentially through the atomizing channel 210 and the outlet channel 121, and finally exit the nozzle 120 through the outlet channel 121. For users to inhale, in this process, since the atomizing component 200 is set inside the inner housing 110 and the mouthpiece 120 is integrally formed with the inner housing 110, the sealing performance of the atomizing component 200 inside the inner housing 110 can be improved, thereby reducing the possibility of leakage of the aerosol matrix in the atomizing component 200. At the same time, it can also reduce the possibility of leakage of aerosol-containing atomized gas, further reducing the pollution to other structures in the aerosol generating device, reducing the waste of aerosol matrix, and improving the user's user experience.

[0043] Continue to refer to Figure 2 As shown in Figure 4, the nozzle 120 includes a nozzle housing 122 and a nozzle outlet pipe 123 disposed within the nozzle housing 122. The aerosol generating device also includes a liquid suction component 300. In the airflow direction, the liquid suction component 300 is disposed between the atomizing component 200 and the nozzle outlet pipe 123, and the liquid suction component 300 is connected to the upstream end of the nozzle outlet pipe 123. The liquid suction component 300 is provided with a vent 310. The upstream end of the vent 310 is connected to the atomizing channel 210, and the downstream end of the vent 310 is connected to the outlet channel 121.

[0044] Specifically, in the above embodiments, the liquid suction assembly 300 is sealed to the upstream end of the suction nozzle outlet tube 123.

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

[0046] Understandably, in terms of airflow direction, since the upstream end of the vent 310 is connected to the atomizing channel 210 and the downstream end of the vent 310 is connected to the outlet channel 121, the atomized gas can flow sequentially through the atomizing channel 210, the vent 310, and the outlet channel 121, and finally flow out of the mouthpiece 120 through the outlet channel 121 for the user to inhale. When the user stops inhaling the atomized gas containing aerosol, the gas in the outlet channel 121 will form condensate in the outlet channel 121. This condensate mixes with the liquid in the user's mouth in the outlet channel 121 and may enter the mouth through the outlet channel 121. Within the atomizing channel 210, since the liquid suction component 300 is positioned between the atomizing component 200 and the mouthpiece outlet pipe 123, and the liquid suction component 300 is connected to the upstream end of the mouthpiece outlet pipe 123, the condensate flowing out through the outlet channel 121 and the liquid in the user's mouth can flow into the vent 310. As the condensate and the liquid in the user's mouth flow through the vent 310, the liquid suction component 300 can absorb the condensate flowing out of the outlet channel 121 and the liquid in the user's mouth. In this way, the atomizing channel 210 can be prevented from being contaminated, and further contamination of the atomizing component 200 can be avoided.

[0047] Reference Figure 2 as well as Figure 5 As shown, the liquid suction assembly 300 includes a first sealing member 320 and a liquid suction member 330. Both the first sealing member 320 and the liquid suction member 330 are disposed inside the nozzle housing 122, and the first sealing member 320 is sealed to the inner wall of the nozzle housing 122. In the airflow direction, the first sealing member 320 is sealed to the upstream end of the nozzle outlet pipe 123. The side of the first sealing member 320 away from the nozzle outlet pipe 123 is provided with a sealing groove 321 with an opening facing the atomizing assembly 200. The liquid suction member 330 is fixedly disposed in the sealing groove 321. The vent hole 310 passes through both the first sealing member 320 and the liquid suction member 330.

[0048] Specifically, in the above embodiments, referring to Figure 7As shown, in the airflow direction, the first sealing member 320 is provided with a connecting hole 324 and a first sub-vent hole 325 communicating with the connecting hole 324. The upstream end of the suction nozzle outlet pipe 123 passes through the connecting hole 324 and is sealed to the hole wall of the connecting hole 324. The outlet hole is connected to the first sub-vent hole 325. The liquid suction member 330 is provided with a second sub-vent hole 331. The two ends of the second sub-vent hole 331 are respectively connected to the first sub-vent hole 325 and the atomization channel 210. The first sub-vent hole 325 and the second sub-vent hole 331 are both part of the vent hole 310. In this way, the first sealing member 320 and the suction nozzle outlet pipe 123 can be sealed through the connecting hole 324, and the atomization channel 210 and the outlet channel 121 can be connected through the first sub-vent hole 325 and the second sub-vent hole 331.

[0049] Specifically, in the above embodiments, referring to Figure 2 As shown, the first seal 320 is connected to the inner wall of the nozzle housing 122 by sealing the outer wall of the sealing groove 321.

[0050] Understandably, since the outer wall of the first seal 320 is sealed to the inner wall of the mouthpiece housing 122, and in the airflow direction, the first seal 320 is sealed to the upstream end of the mouthpiece outlet pipe 123, the first seal 320 can achieve a sealed connection between the liquid suction assembly 300 and the mouthpiece 120, and at the same time, a sealed connection between the liquid suction assembly 300 and the mouthpiece outlet pipe 123. This ensures the airtightness of the atomizing assembly 200, allowing the atomized gas containing aerosol to enter the outlet channel 121 through the atomizing channel 210, thus improving the user experience. At the same time, the liquid suction assembly 330 can absorb the condensate flowing out of the outlet channel 121 and the liquid in the user's mouth, thereby preventing the atomizing channel 210 from being contaminated and further preventing contamination of the atomizing assembly 200. Meanwhile, since the vent 310 passes through both the first seal 320 and the liquid suction member 330, the atomization channel 210 and the air outlet channel 121 can be connected through the vent 310.

[0051] Reference Figure 2 as well as Figure 5 As shown, the liquid suction assembly 300 also includes a second seal 340, which covers the upstream end of the liquid suction assembly 330 along the airflow direction and is sealed to the edge of the opening of the sealing groove 321; wherein, the vent 310 passes through the first seal 320, the second seal 340 and the liquid suction assembly 330.

[0052] Specifically, in the above 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-vent 343. The two ends of the third sub-vent 343 are respectively connected to the second sub-vent 331 and the atomizing channel 210. The first sub-vent 325, the second sub-vent 331 and the third sub-vent 343 are sequentially connected to form a vent 310 to realize the connection between the atomizing channel 210 and the air outlet channel 121. In the airflow direction, the diameter of the downstream end of the third sub-vent 343 is less than or equal to the diameter of the second sub-vent 331 to realize the coverage of the liquid suction member 330 by the second sealing member 340. The diameter of the upstream end of the third sub-vent 343 is greater than or equal to the diameter of the atomizing channel 210 to ensure that the atomized gas in the atomizing channel 210 can enter the third sub-vent 343.

[0053] It is understandable that, since the second seal 340 is installed on the upstream end of the liquid suction member 330 along the airflow direction and is sealed to the edge of the opening of the sealing groove 321, the upstream end of the liquid suction member 330 along the airflow direction can be covered by the second seal 340 to isolate the liquid suction member 330 from the atomizing assembly 200. This prevents condensed substances in the liquid suction member 330 and liquid in the user's mouth from flowing into the atomizing channel 210 from the upstream end of the liquid suction member 330, further preventing the atomizing channel 210 from being contaminated and preventing contamination of the atomizing assembly 200. At the same time, since the vent 310 passes through the first seal 320, the second seal 340 and the liquid suction member 330, the atomizing channel 210 and the air outlet channel 121 can be connected through the vent 310.

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

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

[0056] Understandably, in the airflow direction, since the edge of the downstream end of the sealing part 341 is sealed to the edge of the opening of the sealing groove 321, the sealing part 341 can achieve a sealing connection between the second sealing member 340 and the first sealing member 320, thereby closing the opening of the sealing groove 321. In this way, the sealing part 341 can isolate the liquid suction member 330 from the atomizing assembly 200, thereby preventing condensed substances in the liquid suction member 330 and liquid in the user's mouth from flowing into the atomizing channel from the upstream end of the liquid suction member 330. Within 210, and since the fourth limiting part 342 passes through the limiting gap 323 and abuts against the side wall of the sealing groove 321 and the liquid suction member 330, the position of the liquid suction member 330 in the sealing groove 321 can be limited and fixed by the fourth limiting part 342, so as to prevent the liquid suction member 330 from moving in the direction perpendicular to the airflow direction in the sealing groove 321, thereby ensuring the connectivity between the upstream and downstream of the vent 310, and ensuring that the sealing part 341 can cover the upstream end of the liquid suction member 330 in the airflow direction.

[0057] Specifically, in the above embodiment, the upstream end of the sealing part 341 abuts against the atomizing component 200.

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

[0059] Understandably, since the downstream end of the first seal 320 abuts against the fifth limiting part 1223 and the upstream end of the second seal 340 abuts against the atomizing component 200, the liquid suction component 300 can be fixed between the suction nozzle outlet pipe 123 and the atomizing component 200 to prevent the liquid suction component 300 from moving along the airflow direction, thereby improving the structural stability of the aerosol generating device. At the same time, the fifth limiting part 1223 can also confirm whether the liquid suction component 300 is installed in place.

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

[0061] It is 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 receiving cavity 131, the inner shell 110 can be protected by the first receiving cavity 131, so as to further protect the atomizing component 200. Since the nozzle 120 is at least partially exposed outside the first receiving cavity 131 through the first opening 132, the user's mouth can come into contact with the part of the nozzle 120 exposed outside the first receiving cavity 131, and draw the aerosol-containing atomized gas in the above-mentioned aerosol generating device through this part of the nozzle 120.

[0062] Continue to refer to Figure 4 as well as Figure 9 As shown, the inner shell 110 has a second opening 114 at its upstream end along the airflow direction. 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 cap 140. The end cap 140 has a connecting portion and a sliding portion 141 and a snap-fit ​​portion 142 connected to the connecting portion. The connecting portion is sealed to the edge of the second opening 114. The sliding portion 141 is slidably connected to the guide portion 115. The snap-fit ​​portion 142 is fixedly connected to the third limiting portion 116.

[0063] Specifically, refer to Figure 9 As shown, in the above embodiment, the snap-fit ​​part 142 is a snap fastener, the third limiting part 116 is a limiting groove, the sliding part 141 is a sliding groove, and the guide part 115 is a guide plate. Of course, in other embodiments, the snap-fit ​​part 142 can be a snap groove, the third limiting part 116 can be a limiting snap fastener, the sliding part 141 can be a sliding plate, and the guide part 115 can be a guide groove.

[0064] Understandably, when the sliding part 141 slides along the guide part 115 to the preset position, the locking part 142 engages with the third limiting part 116 to restrict the relative movement between the end cover 140 and the inner housing 110, thus facilitating the assembly between the end cover 140 and the inner housing 110.

[0065] Specifically, in the above embodiments, during the assembly of the atomizing device, the first sealing member 320 is disposed in the mouthpiece housing 122 through the second opening 114 and abuts against the fourth limiting part 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 mouthpiece housing 122 through the second opening 114 and abuts against the first sealing member 320. The atomizing component 200 enters the inner housing 110 through the second opening 114 and abuts against the first sealing member 320. In this way, the atomizing device can be assembled through the second opening 114. During the assembly process, the liquid suction component 300 and the atomizing component 200 can be fixed by the abutment between any two adjacent structures.

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

[0067] Specifically, in the above embodiments, the airflow detection component 400 is sealed 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 embodiments, the aerosol generating device further includes a circuit board (PCBA). A mounting gap is defined between the power supply component 500, the inner housing 110, and the outer housing 130. The circuit board is located within this mounting gap and is electrically connected to the power supply component 500 and the airflow detection component 400, respectively. The power supply component 500 and the atomizing component 200 are located on opposite sides of the same side 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 atomizing component 200 are located on opposite sides of the width direction of the circuit board (e.g., ...). Figure 4 (Left and right sides as shown). The airflow detection component 400 includes a microphone airflow sensor for detecting whether air enters the aerosol generator. Both 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 generator (i.e., air is drawn into the aerosol generator by the user's inhalation), it sends an airflow signal to the circuit board, causing the circuit board to control the atomizing component 200 to be energized and heated, so that the atomizing component 200 atomizes the aerosol matrix, thereby enabling the user to inhale the aerosol.

[0069] It should be noted that in traditional aerosol generators, the airflow detection component 400 is usually located upstream of the airflow direction. The airflow entering the aerosol generator will flow through the airflow detection component 400 and the atomizing component 200 in sequence. Thus, when the user stops inhaling the atomized gas containing aerosol, the aerosol matrix or condensed material in the atomizing component 200 will gradually flow towards the airflow detection component 400 due to gravity, which will contaminate the airflow detection component 400.

[0070] Understandably, since the receiving groove 124 is formed on the nozzle housing 122, and the airflow detection component 400 is fixedly installed within the receiving groove 124, the airflow detection component 400 can be positioned downstream of the airflow direction. This prevents the aerosol matrix or condensed matter within the atomizing component 200 from contaminating the airflow detection component 400, thus extending its service life. During this process, air flows through the opening of the receiving groove 124 to the airflow detection component 400, sequentially passing through the first air inlet 1241, the first airflow detection channel 1222, and the air outlet 1221, achieving the purpose of air flowing through the airflow detection component 400. Simultaneously, since the air outlet 1221 and the first air inlet 1241 are spaced apart from the air outlet channel 121, atomized gas containing the aerosol matrix will not flow through the airflow detection component 400, thereby preventing contamination of the airflow detection component 400 by the aerosol matrix or condensed matter within the atomizing component 200.

[0071] Specifically, in the above embodiments, referring to Figure 4As shown, the end cap 140 is provided with an air intake channel 143 extending along the airflow direction, and the air intake channel 143 is isolated from the first receiving cavity 131. The upstream end of the air intake channel 143 is connected to the outside in the airflow direction, and the downstream end of the air intake channel 143 is connected to the atomizing channel 210, so that airflow passes through the atomizing channel 210. The outer shell 130 has a second air intake 134 and a third air intake 135 spaced apart at the upstream end along the airflow direction, and both the second air intake 134 and the third air intake 135 are connected to the outside. The second air intake 134 is connected to the air intake channel 143, and the third air intake 135 is connected to the first receiving cavity 131. Thus, when the user inhales, air will pass through the second air intake 134. Air 34 enters the air intake channel 143 and then the atomization channel 210. At the same time, air also enters the first receiving cavity 131 through the third air intake 135, flows through the receiving groove 124, and flows through the airflow detection component 400 in the receiving groove 124 to the first air intake 1241. In this way, a second airflow detection channel 136 can be formed between the third air intake 135 and the receiving groove 124. The second airflow detection channel 136 is connected to the first airflow detection channel 1222 and forms an airflow detection channel. In this way, the atomization channel 210 and the airflow detection channel can be isolated to avoid the aerosol matrix or condensed substances 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 seal 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 outlet pipe 123 define a cavity 125, through which the flow path of the first airflow detection channel 1222 passes. The inner housing 110 has a second receiving cavity 111, and the atomizing assembly 200 is disposed within the second receiving cavity 111. The second receiving cavity 111, the atomizing channel 210, and the outlet channel 121 are all isolated from the cavity 125. In the airflow direction, the liquid suction assembly 300 is disposed between the atomizing assembly 200 and the nozzle outlet pipe 123 to isolate the cavity 125 and the second receiving 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 and the cavity 125, through which the flow path of the first airflow detection channel passes.

[0073] It is understandable that the second receiving cavity 111, the atomizing channel 210, and the air outlet channel 121 can be isolated from the cavity 125 by the first sealing element 320, thereby ensuring that the gas in the atomizing channel 210 can only flow through the air outlet channel 121, preventing the atomized gas from entering the cavity 125, thereby improving the utilization rate of the aerosol matrix and enhancing the user 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 assembly 300 along the airflow direction is spaced apart from the inner wall of the suction nozzle housing 122 to connect the first air inlet 1241 and the cavity 125. 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 assembly 300 along the airflow direction is provided with a groove 322. The groove 322 is located close to the air inlet, and one end of the groove 322 is connected to the air inlet. The other end of the groove 322 is connected to the first airflow detection channel 1222 to realize the connection between the first air inlet 1241 and the cavity 125.

[0075] Specifically, in the above embodiments, referring to Figure 2 As shown, the receiving groove 124 is opened near the upstream end of the suction nozzle housing 122. Therefore, in the airflow direction, the receiving groove 124 and the liquid suction assembly 300 are located at the same position. Since the first seal 320 is sealed to the inner wall of the suction nozzle housing 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 airflow in the airflow detection channel.

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

[0077] Reference Figure 2 , Figure 4 , Figure 8 as well as Figure 10 As shown, the aerosol generator also includes a power supply component 500 disposed within the first receiving cavity 131. The axis of the power supply component 500 is parallel to the airflow direction. The power supply component 500 is connected to the airflow detection component 400. The axis of the power supply component 500 is the direction in which the electrodes are located, i.e. Figure 2In the X direction. The outer shell 130 has a first limiting part 133 connected to the cavity wall of the first receiving cavity 131, and the first limiting part 133 protrudes from the cavity wall of the first receiving cavity 131. The inner shell 110 includes a shell part 112 and a second limiting part 113 connected to the outer wall of the shell part 112. The atomizing component 200 is disposed in the shell part 112. In the airflow direction, the second limiting part 113 is disposed between the upstream end and the downstream end of the shell part 112, and the second limiting part 113 and the first limiting part 133 are spaced apart. The two ends of the power supply component 500 abut against the first limiting part 133 and the second limiting part 113, respectively.

[0078] It is understandable that the power supply component 500 can be fixed between the first limiting part 133 and the second limiting part 113 through the first limiting part 133 and the second limiting part 113. At the same time, in the airflow direction, since the second limiting part 113 is located between the upstream end and the downstream end of the housing part 112, and the second limiting part 113 and the first limiting part 133 are spaced apart, the two ends of the power supply component 500 abut against the first limiting part 133 and the second limiting part 113 respectively. Therefore, the atomizing component 200 and the power supply component 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 component 500 can be prevented from interfering with the path of air entering the atomizing channel 210, so that the air can directly enter the atomizing 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 substances in the atomizing component 200 from contaminating the power supply component 500.
