[0034] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the aerosol generating device 10 involved in the embodiment of the present application includes: a device body 100 and a nozzle assembly 200.

[0035] Specifically, the device body 100 is provided with an air flow channel 110, and the suction nozzle assembly 200 includes a first suction nozzle 210 and a second suction nozzle 220. The first suction nozzle 210 is provided with an air guide hole 211, and the air guide hole 211 has a downstream end 2111 and an upstream end 2112 along the air flow direction, and the upstream end 2112 is connected to the air flow channel 110; the second suction nozzle 220 is arranged on the downstream side of the first suction nozzle 210 along the air flow direction, and the second suction nozzle 220 covers the outer surface of the first suction nozzle 210 close to the downstream end 2111, and the second suction nozzle 220 is provided with an air outlet 221, and the air outlet 221 is connected to the downstream end 2111; wherein the second suction nozzle 220 is made of elastic material.

[0036] It should be noted that the airflow direction is Figure 2 The direction that x points to.

[0037] It should be noted that, in the above-mentioned device body 100 , the gas flowing through the airflow channel 110 of the aerosol generating device 10 and the nozzle assembly 200 along the airflow direction is the gas containing the aerosol matrix after atomization.

[0038] In the above-mentioned suction nozzle assembly 200, when the user inhales, the aerosol flows into the first suction nozzle 210 through the air flow channel 110 of the aerosol generating device 10, and flows to the air outlet 221 of the second suction nozzle 220 through the air guide hole 211 of the first suction nozzle 210, and finally enters the user's oral cavity through the air outlet 221. In this process, since the second suction nozzle 220 covers the outer surface of the first suction nozzle 210 close to the downstream end 2111, the user's oral cavity can contact with the second suction nozzle 220, and a squeezing force will be formed on the second suction nozzle 220. Since the second suction nozzle 220 is made of elastic material, when the user's oral cavity contacts and squeezes the second suction nozzle 220, the touch of the oral cavity to the suction nozzle assembly 200 can be improved, thereby improving the taste of the user's inhalation and improving the user's usage experience.

[0039] At the same time, since the material of the second suction nozzle 220 is relatively soft, when the lips are wrapped around the suction nozzle assembly 200, the sealing between the lips and the suction nozzle assembly 200 can be further ensured. When the sealing is better, the suction resistance when the user sucks is also higher, and the suction feeling is stronger, thereby improving the user's experience.

[0040] In the above-mentioned embodiment, the second suction nozzle 220 is made of food-grade elastic material, such as food-grade silicone, PET (polyethylene terephthalate), TPE (thermoplastic elastomer), and the like.

[0041] Reference Figure 2 , Figure 3 as well as Figure 4 As shown, the outer surface of the first suction nozzle 210 is covered by the second suction nozzle 220 at all places, and the second suction nozzle 220 is attached to the outer surface of the first suction nozzle 210; wherein, the first suction nozzle 210 is made of a rigid material.

[0042] It can be understood that, since the outer surface of the first suction nozzle 210 is covered by the second suction nozzle 220 at all places, the surface of the above-mentioned suction nozzle assembly 200 can be made of elastic material. When the user inhales the aerosol in the airflow channel 110 through the above-mentioned suction nozzle assembly 200, it can further ensure that the user's oral cavity is always in contact with the second suction nozzle 220. When the user's oral cavity contacts and squeezes the above-mentioned suction nozzle assembly 200, the touch of the oral cavity to the suction nozzle assembly 200 can be improved. At the same time, since the second suction nozzle 220 is in close contact with the outer surface of the first suction nozzle 210, the shape of the second suction nozzle 220 can be consistent with the shape of the first suction nozzle 210. Since the first suction nozzle 210 is made of a rigid material, the second suction nozzle 220 can be shaped by the first suction nozzle 210. When the user's oral cavity contacts and squeezes the second suction nozzle 220, the second suction nozzle 220 can be prevented from being squeezed and deformed, so as to extend the service life of the above-mentioned suction nozzle assembly 200.

[0043] In the above-mentioned embodiment, the first suction nozzle 210 is made of high temperature resistant food grade plastic, such as PP (polypropylene), PS (polystyrene) and PA (amino plastic) and the like.

[0044] Reference Figure 2 as well as Figure 3 As shown, in the direction perpendicular to the airflow direction, the projection area of ​​the first suction nozzle 210 gradually decreases along the airflow direction.

[0045] It can be understood that, in the direction perpendicular to the airflow, since the projected area of ​​the first suction nozzle 210 gradually decreases along the airflow direction, the projected area of ​​the second suction nozzle 220 can be gradually reduced along the airflow direction. In this way, the above-mentioned suction nozzle assembly 200 can be ergonomic. When the user inhales the aerosol in the airflow channel 110 through the above-mentioned suction nozzle assembly 200, the user's mouth is in a relatively relaxed natural state, so as to reduce the oral muscle fatigue of the user during use, and further improve the user's experience.

[0046] Reference Figure 3 as well as Figure 5 As shown, the first suction nozzle 210 has a guide portion 212 and a suction nozzle portion 213, the air guide hole 211 penetrates the guide portion 212 along the airflow direction, the suction nozzle portion 213 is connected to the device body 100 downstream along the airflow direction, and the suction nozzle portion 213 is connected to an end of the guide portion 212 close to the downstream end 2111 upstream along the airflow direction, and the second suction nozzle 220 is in close contact with the outer surface of the suction nozzle portion 213; wherein, perpendicular to the airflow direction, the projected area of ​​the suction nozzle portion 213 gradually decreases along the airflow direction.

[0047] It can be understood that, since the air guide hole 211 passes through the guide portion 212 along the airflow direction, the guide portion 212 is used to form the air guide hole 211, so that the aerosol matrix atomized in the airflow channel 110 can flow to the air outlet 221 through the air guide hole 211 for the user to inhale. Since the second suction nozzle 220 is in close contact with the outer surface of the suction nozzle portion 213, and the projection area of ​​the suction nozzle portion 213 is gradually reduced along the airflow direction perpendicular to the airflow direction, the suction nozzle portion 213 is used to shape the second suction nozzle 220 to prevent the second suction nozzle 220 from being squeezed and deformed, and at the same time, the suction nozzle portion 213 can make the above-mentioned suction nozzle assembly 200 ergonomic.

[0048] Reference Figure 3 As shown, perpendicular to the direction of air flow, the projected area of ​​the air guiding hole 211 gradually increases along the air flow direction, the projected area of ​​the air outlet 221 gradually increases along the air flow direction, and the projected area of ​​the air outlet 221 is larger than the projected area of ​​the air guiding hole 211.

[0049] It can be understood that when the aerosol enters the air guide hole 211 through the air flow channel 110, the aerosol can gradually diffuse in the air guide hole 211. At the same time, since the projected area of ​​the air outlet 221 gradually increases along the air flow direction, and the projected area of ​​the air outlet 221 is larger than the projected area of ​​the air guide hole 211, when the aerosol enters the air outlet 221 through the air guide hole 211, the aerosol can further diffuse at the air outlet 221, so that the aerosol can quickly fill the oral cavity, thereby improving the user's inhalation taste.

[0050] Continue to refer to Figure 3 as well as Figure 5 As shown, between the upstream end 2112 and the downstream end 2111 , the suction nozzle portion 213 is gradually recessed toward the airflow guide portion 212 along the airflow direction.

[0051] It can be understood that, between the upstream end 2112 and the downstream end 2111, since the nozzle portion 213 is gradually recessed toward the flow guide portion 212 along the airflow direction, when the user inhales the aerosol in the airflow channel 110 through the nozzle assembly 200, the tension of the second nozzle 220 on the user's oral cavity can be further reduced, so that the nozzle assembly 200 can be more ergonomic, further reduce the user's oral muscle fatigue during use, and improve the user's experience.

[0052] Continue to refer to Figure 3 as well as Figure 5 As shown, between the upstream end 2112 and the downstream end 2111, the guide portion 212 and the suction nozzle portion 213 are spaced apart to define a cavity 214, and the suction nozzle assembly 200 also includes a liquid absorbent member 230, which is disposed in the cavity 214, and an end of the guide portion 212 close to the upstream end 2112 is accommodated in the liquid absorbent member 230.

[0053] It is understandable that during the use of the above-mentioned nozzle assembly 200, the liquid in the user's oral cavity may enter the air guide hole 211 from the air outlet 221, and thus, may further enter the air flow channel 110 through the air guide hole 211, and thus, may cause pollution to the inside of the above-mentioned aerosol generating device 10. At the same time, when the user stops inhaling the atomized aerosol matrix, the gas in the air guide hole 211 will form condensed substances in the air guide hole 211, and the condensed substances will mix with the liquid in the user's oral cavity in the air guide hole 211, and may pass through the air guide hole 211 to the air flow channel 110. 1 enters the air flow channel 110. Since the liquid absorbent 230 is arranged in the cavity 214, and the end of the air guide portion 212 close to the upstream end 2112 is accommodated in the liquid absorbent 230, the end of the air guide portion 212 close to the upstream end 2112 can be hidden in the liquid absorbent 230. Therefore, the liquid in the user's oral cavity or the mixed liquid of the condensed material and the liquid in the user's oral cavity flowing out from the upstream end 2112 of the air guide through hole 211 can be absorbed by the liquid absorbent 230, so that the air flow channel 110 can be prevented from being polluted, and further the above-mentioned aerosol generating device 10 can be prevented from being polluted.

[0054] Reference Figure 2 as well as Figure 3 As shown, the liquid absorbing member 230 is provided with an avoidance through hole 231, which is connected to the air flow channel 110, and one end of the guide portion 212 close to the upstream end 2112 is penetrated into the avoidance through hole 231, and the hole wall of the avoidance through hole 231 is in close contact with the outer wall of the guide portion 212, and the upstream end 2112 is spaced apart from the air flow channel 110.

[0055] It can be understood that, since the avoidance through hole 231 is connected to the airflow channel 110, one end of the guide portion 212 close to the upstream end 2112 is arranged in the avoidance through hole 231. Therefore, when the user inhales the aerosol in the airflow channel 110 through the above-mentioned nozzle assembly 200, the gas in the airflow channel 110 can flow through the avoidance through hole 231 and the air guide through hole 211 in sequence. At the same time, since the upstream end 2112 is spaced apart from the airflow channel 110, when the liquid or condensed material in the user's mouth is in contact with the aerosol in the user's mouth, the gas in the airflow channel 110 can flow through the avoidance through hole 231 and the air guide through hole 211 in sequence. When the mixture of liquid flows out through the upstream end 2112 of the air guide hole 211, the liquid in the user's mouth or the mixture of condensed matter and liquid in the user's mouth can be prevented from directly flowing into the air flow channel 110, thereby preventing the air flow channel 110 from being contaminated. Furthermore, since the hole wall of the avoidance hole 231 is in close contact with the outer wall of the guide part 212, the liquid in the user's mouth or the mixture of condensed matter and liquid in the user's mouth can be absorbed by the liquid absorbent member 230, thereby further ensuring that the air flow channel 110 will not be contaminated.

[0056] Reference Figure 2 as well as Figure 6As shown, the device body 100 has a sealing part 120, and the device body 100 is provided with a mounting groove 130 whose opening direction is consistent with the airflow direction, and the groove wall of the mounting groove 130 along the airflow direction is one of the surfaces of the sealing part 120, and the first suction nozzle 210 is detachably arranged in the mounting groove 130 and abuts against the sealing part 120; wherein, the airflow channel 110 is opened on the sealing part 120, and the sealing part 120 is also provided with a liquid injection hole 121 extending along the airflow direction, the liquid injection hole 121 is spaced apart from the airflow channel 110, and the downstream end of the liquid injection hole 121 along the airflow direction is connected to the mounting groove 130.

[0057] Reference Figure 6 As shown, in the above-mentioned embodiment, one end of the liquid injection hole 121 upstream along the air flow direction is connected to the liquid storage tank 140 in the device body 100.

[0058] It can be understood that when the first suction nozzle 210 is arranged in the installation groove 130, the first suction nozzle 210 and the sealing part 120 are abutted against each other, thereby, the inside of the device body 100 can be sealed through the sealing part 120 to prevent foreign matter from entering the device body 100 through the above-mentioned suction nozzle assembly 200. At the same time, since the air flow channel 110 is provided on the sealing part 120, when the user inhales, the aerosol flows into the first suction nozzle 210 of the suction nozzle assembly 200 through the sealing part 120, and flows to the suction nozzle through the air guide hole 211 of the first suction nozzle 210. The air outlet 221 of the second suction nozzle 220 of the mouth assembly 200 eventually enters the user's oral cavity through the air outlet 221. Furthermore, in the above-mentioned embodiment, the liquid injection hole 121 is used to add the aerosol matrix into the liquid storage tank 140. Since the downstream end of the liquid injection hole 121 of the sealing portion 120 along the air flow direction is connected to the mounting groove 130, when it is necessary to add the aerosol matrix into the device body 100, the above-mentioned suction nozzle assembly 200 can also be removed from the mounting groove 130, and the aerosol matrix can be added to the liquid injection hole 121.

[0059] In the above-mentioned embodiment, referring to Figure 5 as well as Figure 6 As shown, the first suction nozzle 210 is clamped with the groove wall of the installation groove 130, and a protrusion 215 is provided at the connection between the first suction nozzle 210 and the installation groove 130. A clamping groove 131 is provided at the connection between the groove wall of the installation groove 130 and the first suction nozzle 210. When the first suction nozzle 210 is set in the installation groove 130, the protrusion 215 is penetrated into the clamping groove 131 and abuts against the groove wall of the clamping groove 131. In this way, the clamping connection between the first suction nozzle 210 and the groove wall of the installation groove 130 can be achieved.

[0060] Furthermore, in other embodiments, the connection between the first suction nozzle 210 and the groove wall of the installation groove 130 may also be a detachable connection such as a threaded connection or an elastic snap connection.

[0061] Reference Figure 2 As shown, one downstream end of the liquid absorbing member 230 of the nozzle assembly 200 along the airflow direction abuts against the sealing portion 120 , and the liquid absorbing member 230 covers one downstream end of the liquid injection through hole 121 along the airflow direction.

[0062] It can be understood that, since the downstream end of the liquid absorbent member 230 of the suction nozzle assembly 200 along the airflow direction abuts against the sealing portion 120, the sealing of the device body 100 can be further improved by the liquid absorbent member 230. At the same time, since the liquid absorbent member 230 covers the downstream end of the liquid injection hole 121 along the airflow direction, when the above-mentioned suction nozzle assembly 200 is installed in the installation groove 130, the liquid injection hole 121 can be blocked by the liquid absorbent member 230, thereby further improving the sealing of the device body 100.
