Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of aerosol generation, and more particularly, relates to an air inlet support and an aerosol generating device. BACKGROUND

[0002] An aerosol generating device is an electronic product for users to use, which utilizes an atomizer to heat and atomize an aerosol substrate into an aerosol. The aerosol generating device in the related art includes an atomization assembly, wherein an air hole for supplying ambient air to the atomization assembly is a single air hole. In order to ensure the preparation amount of the aerosol, the cross-sectional area of the single air hole is often designed to be large.

[0003] In actual use, a certain amount of condensate will be formed in the aerosol generating device. Since the cross-sectional area of the single air hole is large, the condensate lacking effective blocking will flow out along the air hole. This not only causes the inside and outside of the aerosol generating device to be contaminated by the condensate, but also causes the waste of the aerosol substrate and affects the user experience due to the fact that the condensate flowing out cannot be utilized. CONTENT OF THE UTILITY MODEL

[0004] Embodiments of the application provide an air inlet support and an aerosol generating device to at least partially solve one of the technical problems in the related art and optimize the user experience of the aerosol generating device.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the application is as follows: in a first aspect, an air inlet support is provided, which is applied to an aerosol generating device having an atomization assembly. The air inlet support includes a support body and a guide portion. The support body is a hollow structure and has a first end and a second end in the axial direction. A first air inlet is arranged on the support body. The guide portion is formed in the support body. One end of the guide portion is in communication with the first air inlet, and the other end is arranged adjacent to the first end. A second air inlet is arranged on the guide portion and is in communication with the first air inlet.

[0006] The second air inlet includes a plurality of air inlet holes. The inner diameter of any one of the air inlet holes is not more than 0.6 mm.

[0007] The gas flowing into the air inlet bracket through the first air inlet can enter the bracket main body through the second air inlet. By setting the second air inlet to include a plurality of air inlet small holes and the inner diameter of any one of the air inlet small holes being not more than 0.6 mm, the gas flow flowing into the air inlet bracket can be dispersed. In addition, due to the small inner diameter of the air inlet small hole, the liquid is not easy to flow to the first air inlet through the air inlet small hole due to the influence of surface tension and other factors at the air inlet small hole, so that the overflow of the condensed liquid can be effectively prevented, and the protection of other parts is facilitated. In the next use, the condensed liquid accumulated around the air inlet small hole can be re-atomized, realizing the reuse of the condensed liquid, and helping to improve the user experience.

[0008] Optionally, the inner diameter of the air inlet small hole is 0.4 mm to 0.6 mm.

[0009] Optionally, the number of air inlet small holes is 9 and arranged regularly.

[0010] Optionally, the inner diameter of the air inlet small hole is 0.5 mm.

[0014] Optionally, the air inlet bracket further includes a support portion, the support portion is located in the bracket main body and between the first end and the second end, and the support portion, the bracket main body and the guide portion enclose to form the containing groove.

[0019] The atomization air inlet and the second air inlet are kept staggered in space in the aerosol generating device provided by the embodiments of the present application, which helps to further improve the leakage problem of the condensate. When the liquid leakage problem of the aerosol forming substrate or the like occurs inside the aerosol generating device, since the second air inlet is staggered with the atomization air inlet, the liquid leaked through the atomization air inlet will not directly flow to the second air inlet, further enhancing the protection of the liquid outflow through the second air inlet, improving the use performance of the aerosol generating device, and improving the user's use experience.

[0020] Optionally, the atomization air inlet is located on one side of the second air inlet close to the first end.

[0022] The circuit board is fixedly connected with the second end of the air inlet support, and a relief hole is formed in the circuit board, and along the axial direction of the air inlet support, the relief hole at least partially overlaps with the first air inlet;

[0023] The sealing air guide member is mounted between the first air inlet and the second air inlet through the first air inlet, and a first air guide channel is formed in the sealing air guide member to communicate the first air inlet and the second air inlet.

[0024] Optionally, the circuit board is further provided with an air flow detection element.

[0025] A second air guide channel is formed in the sealing air guide member, one end of the second air guide channel is sealingly connected with the circuit board, and the other end is in communication with the second air inlet.

[0026] Optionally, a guide air inlet is formed in the guide portion and is spaced apart from the second air inlet, and along the axial direction of the air inlet support, the guide air inlet is opposite to the second air guide channel.

[0027] Optionally, a sealing protruding ring is protruded on one side surface of the sealing air guide member in contact with the circuit board, and the sealing protruding ring is arranged around the second air guide channel.

[0028] When the sealing air guide member is in contact with the circuit board, the sealing protruding ring abuts against the surface of the circuit board to block the air flow detection element.

[0029] Optionally, the aerosol generating device further comprises a mounting seat, and the mounting seat is located between the air inlet support and the atomization assembly.

[0030] The middle part of the mounting seat is provided with a third air guide channel and a guide side wall, the third air guide channel is communicated with the second air inlet and the atomization air inlet, and the guide side wall is located on the side of the third air guide channel away from the second air inlet and is inclined towards the direction away from the first end.

[0032] The air inlet support provided by the embodiments of the present application can improve the problem of outflow of the condensate through the second air inlet through the small-diameter air inlet hole, which not only helps to protect other components in the aerosol generating device, but also avoids the pollution of the condensate to the interior and appearance of the aerosol generating device, and improves the user experience; at the same time, the condensate remaining in the air inlet support can be reused when the aerosol generating device is started again, which can improve the waste problem of the condensate and improve the utilization rate of the aerosol forming substrate.

[0060] The embodiments of the present application provide an air inlet support 10 and an aerosol generating device 100, wherein the aerosol generating device 100 is a device for generating aerosol, including but not limited to a heating element, a power supply assembly, a control unit, and an air flow channel, etc., and the device has a liquid storage device for storing a certain amount of aerosol forming substrate. The heating element is the core component of the aerosol generating device 100, which can generate heat by the principle of electric resistance heating and act on the aerosol forming substrate to generate aerosol under the condition that the power supply assembly provides electric energy; the power supply assembly is used to provide electric energy to the heating element, which can be a built-in rechargeable battery (such as a lithium battery, etc.), or can be connected to an external power source through an external power source interface to obtain electric energy. The power supply assembly usually also includes some circuit protection devices, such as overcurrent protection, overvoltage protection, etc., to ensure that the aerosol generating device 100 works in a safe voltage and current range; the control unit is the part of the whole regulation of the aerosol generating device 100, which can be a switching circuit or a control system containing a microprocessor, used to control the switching of the heating element, the heating time, the heating temperature, etc.; the air flow channel is used to guide the flow of air, one end of which is connected to the outside environment, and the other end is connected to the suction nozzle for the user to inhale. When the aerosol generating device 100 works, air flows into the inside of the aerosol generating device 100 through the air flow channel, and carries the heated aerosol to the suction nozzle for the user to inhale in the process of flowing.

[0061] The liquid storage device can be installed inside the aerosol generating device 100 and arranged close to the suction nozzle. The aerosol generating device 100 stored in the liquid storage device can be transported to the heating element by the liquid guide component with the transportation function.

[0062] The above-mentioned liquid guide component can be a porous material support for transporting the aerosol forming substrate. The remaining heating element, power supply assembly, control unit, and air flow channel can refer to the existing structure in the related art, which will not be described in detail in this application.

[0063] Generally, the above-mentioned airflow passage is connected by passages formed on different components in sequence, for example, the air inlet support 10 located inside the aerosol generating device 100. The airflow can flow to the atomization assembly 20 through the air inlet support 10, and carry the aerosol generated by heating at the atomization assembly 20 to the mouthpiece for the user to inhale. When the aerosol generating device 100 stops working, part of the aerosol remaining in the device gradually reduces in temperature and forms condensate. The above-mentioned condensate can remain in the device and flow into the air inlet passage on the air inlet support 10 due to shaking of the device, etc. Accordingly, the above-mentioned condensate can contaminate the air inlet passage and other components connected thereto to some extent, and part of the condensate can also flow out of the aerosol generating device 100 through the air inlet passage, thereby causing stains on the surface of the device and also leading to waste of the condensate, which affects the user experience to some extent.

[0064] To overcome the above-mentioned problems, improve the user experience, and improve the utilization rate of the aerosol forming substrate to some extent, the embodiments of the present application provide an air inlet support 10 and an aerosol generating device 100 having the same.

[0065] Figure 1 A structural schematic diagram of the air inlet support 10 provided by the embodiments of the present application is shown in Figure 2 A structural schematic diagram of the air inlet support 10 provided by the embodiments of the present application is shown in Figure 1 A structural schematic diagram of the air inlet support 10 provided by the embodiments of the present application is shown in Figure 3 A structural schematic diagram of the air inlet support 10 provided by the embodiments of the present application is shown in Figure 1 A structural schematic diagram of the air inlet support 10 provided by the embodiments of the present application is shown in Figure 4 A structural schematic diagram of the air inlet support 10 provided by the embodiments of the present application is shown in Figure 3 A structural schematic diagram of the air inlet support 10 provided by the embodiments of the present application is shown in

[0066] In a first aspect, the embodiments of the present application provide an air inlet support 10 applied to an aerosol generating device 100 having an atomization assembly 20. The above-mentioned air inlet support 10 can be used in cooperation with the atomization assembly 20 to ensure that the liquid aerosol forming substrate formed between the air inlet support 10 and the atomization assembly 20 does not flow out through the air inlet support 10, thereby improving the user experience. In addition, the air inlet support 10 also helps to realize the secondary use of the liquid aerosol forming substrate located in the above-mentioned space, thereby improving the utilization rate of the aerosol forming substrate.

[0067] Please refer to Figure 1 , Figure 2 and Figure 3 , the above-mentioned air inlet support 10 includes a support body 1 and a guide portion 2 fixedly connected, wherein the support body 1 is a hollow structure, and the support body 1 has a first end 101 and a second end 102 oppositely arranged along the axial direction thereof, and the guide portion 2 is formed in the support body 1.

[0068] Please refer to Figure 2The first air inlet 11 is arranged on the bracket body 1, one end of the guide part 2 is communicated with the first air inlet 11, and the other end points to the first end 101 of the bracket body 1. The second air inlet 201 is arranged on the guide part 2 and communicated with the first air inlet 11, and the second air inlet 201 comprises a plurality of air inlet small holes 202, and the inner diameter of any one of the air inlet small holes 202 is not more than 0.6 mm.

[0069] In the air inlet bracket 10 provided by the embodiment of the present application, the gas flowing in through the first air inlet 11 can enter the bracket body 1 through the second air inlet 201. By arranging the second air inlet 201 to comprise a plurality of air inlet small holes 202 and the inner diameter of any one of the air inlet small holes 202 being not more than 0.6 mm, the gas flow flowing into the air inlet bracket 10 can be dispersed. In addition, due to the small inner diameter of the air inlet small holes 202, the liquid is not easy to flow to the first air inlet 11 through the air inlet small holes 202 due to the influence of surface tension and other factors, so that the overflow of the condensed liquid can be effectively prevented, and the protection of other parts is facilitated. In the next use, the condensed liquid accumulated around the air inlet small holes 202 can be re-atomized, realizing the reuse of the condensed liquid, and helping to improve the user experience.

[0070] It can be understood that the bracket body 1 and the guide part 2 can be an integrated structure, so as to simplify the processing process, improve the production efficiency, and at the same time, the integrated structure is also helpful to improve the overall strength of the air inlet bracket 10, and further avoid the possibility of liquid leakage at the contact part of the bracket body 1 and the guide part 2.

[0071] In some embodiments, the first air inlet 11 can be arranged on the axial outer side of the bracket body 1, at this time, the cavity which is communicated with the first air inlet 11 and the second air inlet 201 is formed between the guide part 2 and the inner side wall of the bracket body 1. In other similar embodiments, please refer to Figure 2 The first air inlet 11 can be formed on the second end 102 of the bracket body 1. The first air inlet hole can be formed by the bracket body 1 and the guide part 2.

[0072] In some embodiments, the second air inlet 201 can be arranged on the side of the guide part 2 close to the middle part of the bracket body 1, or can be arranged on the side of the guide part 2 pointing to or close to the first end 101 of the bracket body 1, please refer to Figure 1 and Figure 3 At this time, the guide part 2 is located on the inner side wall of the bracket body 1 and protrudes inward relative to the surface of the inner side wall of the bracket body 1.

[0073] Specifically, the guide part 2 comprises a first connecting side wall 21 and an air inlet side wall 22 which are connected, wherein the air inlet side wall 22 is located on the side of the bracket body 1 close to the first end 101, and the second air inlet 201 is arranged on the air inlet side wall 22, please refer to Figure 1 andFigure 3 The first connecting side wall 21 is located in the bracket body 1, one end of which is connected with the air inlet side wall 22, and the other end extends along the axial direction of the bracket body 1 to the second end 102, so as to cooperate with the bracket body 1 to form the first air inlet 11. Please refer to Figure 2 The cross section of the first connecting side wall 21 and the air inlet side wall 22 in the axial direction of the bracket body 1 is L-shaped or similar L-shaped structure. Please refer to Figure 4 .

[0074] The second air inlet 201 formed on the air inlet side wall 22 includes at least two air inlet holes 202, and the inner diameter of any one of the air inlet holes 202 is between 0.4mm and 0.6mm. Please refer to Figure 3 The plurality of air inlet holes 202 are arranged in sequence and at intervals. In use, the airflow can flow into the air inlet bracket 10 through the plurality of air inlet holes 202 arranged in sequence and at intervals, and then flow to the atomization assembly 20. In the above process, the condensate formed in the air inlet bracket 10 is not easy to flow out from the air inlet holes 202 due to the influence of surface tension and the like, so as to improve the leakage problem of the condensate. In addition, the condensate accumulated at the air inlet holes 202 and around the air inlet holes 202 can be atomized again in the subsequent use process, so as to realize the reuse of the condensate.

[0075] When the number of air inlet holes 202 is large, the plurality of air inlet holes 202 are regularly arranged.

[0076] The regular arrangement can be understood as that the plurality of air inlet holes 202 are regularly arranged along a fixed straight line or curve, or the plurality of air inlet holes 202 are arranged in a rectangular array, or the plurality of air inlet holes 202 are arranged in a circular array, or the plurality of air inlet holes 202 are arranged in sequence and at intervals to form a specific pattern, etc.

[0077] Please refer to Figure 3 The number of the above-mentioned air inlet holes 202 can be 9, and the 9 air inlet holes 202 are arranged in an array on the side of the guide portion 2 directed to the first end 101, i.e. on the air inlet side wall 22.

[0078] It should be noted that the total area of the plurality of air inlet holes 202 should be kept equivalent or substantially consistent with the opening area (pore cross-sectional area) of the single air inlet in other technical solutions, so as to ensure that the air inlet amount meets the working requirements of the aerosol generating device 100.

[0079] It can be understood that, under the condition that the air inlet amount is unchanged, the smaller the opening area of the air inlet hole 202, the more the number of the air inlet holes 202.

[0080] Based on the processing consideration, the opening sizes of all the air inlet holes 202 can be set to be the same.

[0081] In some embodiments, the inner diameter of the above-mentioned air inlet small holes 202 is set to be 0.5 mm, and the number of the air inlet small holes 202 is set to be 9.

[0082] In other similar embodiments, the side surface of the air inlet side wall 22 towards the first end 101 can be set to be protruded and form a liquid blocking protrusion which blocks the flow of the condensed liquid. The orthographic projection of the liquid blocking protrusion is set to surround all the air inlet small holes 202 in the axial direction of the air inlet support 10.

[0083] In order to further improve the use effect of the air inlet support 10 and prevent the condensed liquid in the air inlet support 10 from flowing randomly in the air inlet support 10, in some embodiments, the air inlet support 10 further comprises a containing groove 3 in the support body 1. The containing groove 3 can be used to place a liquid storage member which can be made of oil absorbing cotton or similar materials and is used to absorb the condensed liquid in the air inlet support 10.

[0084] Specifically, the oil absorbing cotton can be made of non-woven fabric or organic cotton.

[0085] Specifically, along the axial direction of the air inlet support 10, the orthographic projection of the containing groove 3 is set to be spaced apart from the orthographic projection of the second air inlet 201.

[0086] Referring to Figure 3 and Figure 4 , the above-mentioned containing groove 3 is formed between the guide part 2 and the support body 1 and is independent of the air flow channel formed between the first air inlet 11 and the second air inlet 201 through the guide part 2.

[0087] Specifically, the air inlet support 10 further comprises a support part 4 which can be connected to the support body 1 and the guide part 2 to enclose the above-mentioned containing groove 3.

[0088] Referring to Figure 4 , the support part 4 in the support body 1 is located between the first end 101 and the second end 102, and the support part 4, the support body 1 and the guide part 2 enclose to form the containing groove 3.

[0089] The support part 4 comprises a support plate 41 and a second connecting side wall 42, wherein the support plate 41 is in a plate structure, one side close to the middle of the support body 1 is fixedly connected to the second connecting side wall 42, and the other side away from the middle of the support body 1 is fixedly connected to the first connecting side wall 21. The containing groove 3 is formed between the first connecting side wall 21, the second connecting side wall 42 and the support plate 41 and is in an annular groove structure.

[0090] Specifically, the support plate 41 is fixedly connected to the side of the first connecting side wall 21 which points to the second end 102. Referring to Figure 4The first connecting side wall 21 and the second connecting side wall 42 are oppositely arranged, and the second connecting side wall 42 is located on the side of the first connecting side wall 21 close to the middle of the support body 1.

[0091] It can be understood that the air inlet support 10 provided by the embodiment of the present application can improve the problem of outflow of the condensed liquid through the second air inlet 201 by adjusting the second air inlet 201 arranged on the side facing the atomization assembly 20 to a plurality of air inlet holes 202, without affecting the overall air intake amount of the air inlet support 10. The above structural improvement not only helps to protect other components inside the aerosol generating device 100, but also avoids the pollution of the condensed liquid to the inside and appearance of the aerosol generating device 100, and improves the user's experience; at the same time, the condensed liquid remaining in the air inlet support 10 can be reused when the aerosol generating device 100 is started again, so as to improve the utilization rate of the aerosol forming substrate.

[0092] Based on the same concept, in a second aspect, the embodiment of the present application also provides an aerosol generating device 100, comprising Figures 5-12 .

[0094] Please refer to Figure 5 and Figure 6 , the aerosol generating device 100 comprises an atomization assembly 20, an air inlet support 10, a circuit board 30, a sealing air guide piece 40 and a mounting seat 50, wherein the atomization assembly 20 and the circuit board 30 are respectively located at the first end 101 and the second end 102 of the air inlet support 10, the sealing air guide piece 40 is located between the air inlet and the circuit board 30, and the mounting seat 50 is located in the air inlet support 10 and is used for fixing and supporting the atomization assembly 20.

[0095] Please refer to Figure 6 The atomization assembly 20 has an atomization air inlet 210, which is directed into the air inlet support 10, and the first end 101 of the air inlet support 10 is arranged adjacent to the atomization air inlet 210. It should be noted that the atomization air inlet 210 and the second air inlet 201 on the air inlet support 10 are spatially staggered.

[0096] The atomization air inlet 210 and the second air inlet 201 that are spatially staggered help to further improve the leakage problem of the condensed liquid. When the liquid leakage problem of the aerosol forming substrate or the like occurs inside the aerosol generating device 100, since the second air inlet 201 is staggered with the atomization air inlet 210, the liquid leaked through the atomization air inlet 210 will not directly flow into the second air inlet 201 when flowing to the air inlet support 10, further enhancing the protection of the liquid flowing out through the second air inlet 201, improving the use performance of the aerosol generating device 100, and improving the user's use experience.

[0097] It can be understood that the liquid leaked through the atomization air inlet 210 can flow into the containing groove 3 arranged in the support body 1. The liquid storage member arranged in the containing groove 3 can adsorb the condensed liquid, so as to better avoid the leakage of the condensed liquid.

[0098] Specifically, the first end 101 of the air inlet support 10 is arranged around the atomization assembly 20. Please refer to Figure 6 , along the axial direction of the air inlet support 10, the orthographic projection of the atomization assembly 20 is located within the projection range of the air inlet support 10.

[0099] It can be understood that the above-mentioned "spatially staggered" means that the atomization air inlet 210 and the second air inlet 201 are staggered.

[0100] Specifically, the above-mentioned staggering includes various different cases. For example, in the direction perpendicular to the axis of the air inlet support 10, the atomization air inlet 210 and the second air inlet 201 are arranged at intervals, so that the straight line extending in the axial direction from any one of the air inlet holes 202 in the second air inlet 201 will not pass through the atomization air inlet 210; and / or, along the axial direction of the air inlet support 10, the center position of the atomization air inlet 210 is offset from the center position of the second air inlet 201, and the offset amount is sufficient to make the orthographic projection of the atomization air inlet 210 not coincide with the orthographic projection of the second air inlet 201.

[0101] The second air inlet 201 and the atomization air inlet 210 are spatially staggered, that is, neither are located on the same horizontal plane nor on the same axis. Therefore, the structure can further reduce the probability of the condensed liquid flowing out of the atomization air inlet 210 directly flowing to the position of the second air inlet 201, and further reduce the possibility of the condensed liquid flowing out of the second air inlet 201.

[0102] Under the premise of maintaining the staggered arrangement, the end of the atomization air inlet 210 is located on the side of the second air inlet 201 away from the first end 101, or the end of the atomization air inlet 210 is located on the side of the second air inlet 201 close to the first end 101 along the axial direction of the air inlet support 10.

[0103] Please refer to Figure 6 , the end of the atomization air inlet 210 is located on the side of the second air inlet 201 facing the first end 101. This structure can improve the flow direction of the gas flow to reduce the influence of the gas flow on the aerosol.

[0104] It should be noted that the distance between the plane where the second air inlet 201 is located and the plane where the atomization air inlet 210 is located should not be too large, otherwise, the axial size of the aerosol generating device 100 will be too large.

[0105] In order to better guide the condensed liquid flowing out of the atomization assembly 20 to the accommodation groove 3 and reduce the possibility of the condensed liquid flowing to the second air inlet 201, in some embodiments, a mounting seat 50 is further provided between the atomization assembly 20 and the air inlet support 10, please refer to Figure 6 , the mounting seat 50 is used to guide the condensed liquid flowing out of the atomization assembly 20 to flow into the accommodation groove 3.

[0106] Please refer to Figure 7 and Figure 8 , along the axial direction of the air inlet support 10, both ends of the mounting seat 50 are connected to the atomization assembly 20 and the air inlet support 10 respectively, and the middle part of the mounting seat 50 forms a third air guide channel 510 which can communicate the second air inlet 201 and the atomization air inlet 210.

[0107] The side of the third air guide channel 510 close to the air inlet support 10 is a perforated structure, one end of the perforated structure points to the position of the second air inlet 201, and the other end has an inclined guide side wall 520.

[0108] Specifically, the guide side wall 520 is located on the side of the third air guide channel 510 away from the second air inlet 201 and inclined towards the direction away from the first end 101, and points to the accommodation groove 3 located in the air inlet support 10. The condensed liquid dripping from the atomization air inlet 210 falls on the bottom surface of the perforated structure, and then flows along the guide side wall 520 to the accommodation groove 3.

[0109] Referring to Figure 9 and Figure 10 , the circuit board 30 is fixedly connected with the air inlet support 10 through the second end 102 of the air inlet support 10, and the sealing air guide member 40 is located between the circuit board 30 and the air inlet support 10.

[0110] In some embodiments, the circuit board 30 can be fixedly connected with the air inlet support 10 in a clamping manner, and the air inlet support 10 is provided with a clamping hook for connecting with the circuit board 30.

[0111] Correspondingly, the circuit board 30 is provided with an avoiding hole 310. In the axial direction of the air inlet support 10, the orthogonal projection of the avoiding hole 310 at least partially overlaps with the orthogonal projection of the first air inlet 11. The airflow can pass through the avoiding hole 310 formed on the circuit board 30 to flow to the first air inlet 11, and then flow through the first air inlet 11 and the second air inlet 201 to flow into the atomizing air inlet 210.

[0112] Specifically, the opening size of the avoiding hole 310 is smaller than that of the first air inlet 11. In the axial direction of the air inlet support 10, the orthogonal projection of the avoiding hole 310 is located within the orthogonal projection of the first air inlet 11. Of course, in other similar embodiments, the opening size of the avoiding hole 310 can be greater than that of the first air inlet 11, and the orthogonal projection of the first air inlet 11 in the axial direction is located within the orthogonal projection of the avoiding hole 310 in the axial direction.

[0113] Referring to Figure 10 and Figure 11 , the sealing air guide member 40 is used for guiding the airflow to flow through the avoiding hole 310 and the first air inlet 11 to the second air inlet 201. The sealing air guide member 40 can be installed between the first air inlet 11 and the second air inlet 201 through the first air inlet 11, and the sealing air guide member 40 is provided with a first air guide channel 410 which communicates the first air inlet 11 and the second air inlet 201.

[0114] Specifically, the sealing air guide member 40 is installed between the support body 1 and the guide part 2, the first air guide channel 410 is arranged through the sealing air guide member 40, and the two ends of the first air guide channel 410 are just opposite to the first air inlet 11 and the second air inlet 201.

[0115] Referring to Figure 12 , the circuit board 30 is further provided with an airflow detection element 320, and the airflow detection element 320 is located on the side of the circuit board 30 facing the sealing air guide member 40.

[0116] The second air guide channel 420 is formed in the sealing air guide member 40, and one end of the second air guide channel 420 is in sealing connection with the circuit board 30, and the other end is in communication with the second air inlet 201. At this time, the airflow detection element 320 is at least partially located in the sealing air guide member 40 through the second air guide channel 420. That is, the second air guide channel 420 is in communication with the airflow detection element 320.

[0117] The airflow detection element 320 can detect the airflow flow by sensing the airflow. For example, the airflow detection element 320 can detect the airflow flow by detecting the physical values such as airflow velocity and pressure change, to reflect the change of the airflow. For example, the airflow detection element 320 can be a microphone.

[0118] Specifically, the second air guide channel 420 is partially formed in the sealing air guide member 40, and the second air guide channel 420 is in communication with the airflow detection element 320 and the second air inlet 201.

[0119] Please refer to Figure 10 and Figure 12 The sealing air guide member 40 is provided with a sealing protruding ring 430 on the side surface in contact with the circuit board 30, and the sealing protruding ring 430 is arranged around the one end of the second air guide channel 420 facing the circuit board 30.

[0120] When the sealing air guide member 40 is in contact with the circuit board 30, the sealing protruding ring 430 abuts against the surface of the circuit board 30 to achieve effective sealing of the airflow detection element 320 in the circumferential direction. At this time, the airflow detection element 320 can be connected to the one end of the second air guide channel 420 facing away from the circuit board 30 through the second air guide channel 420 to achieve detection of the change of the airflow.

[0121] When the user inhales, the airflow flows to the atomization air inlet 210 through the second air inlet 201. In this process, the airflow in the second air guide channel 420 also changes to a certain extent. Correspondingly, the airflow detection element 320 located in the second air guide channel 420 communicates with the external environment through the second air guide channel 420 and identifies the user's inhalation action to achieve detection of the change of the airflow.

[0122] The airflow detection element 320 can convert the detected airflow change signal into an electrical signal. The circuit board 30 responds to the electrical signal output at the airflow detection element 320 to determine whether the user performs the inhalation action, and then triggers the subsequent working process. For example, when the user inhales, the atomization assembly 20 is started to heat the condensate and the aerosol-forming substrate to convert them into aerosol for smoking; after the user stops inhaling, the atomization assembly 20 is turned off, etc.

[0123] Please refer to Figure 12The first air guide channel 410 and the second air guide channel 420 are spaced apart on the sealing air guide 40 and are independent of each other, which can further ensure that the air flow detection element 320 for identifying the user's puffing action can only be connected to the external environment through the second air guide channel 420 and is separated from other parts on the air inlet support 10, so that the air flow detection element 320 is better protected from condensate or oil formed during the operation of the atomization assembly 20 from leaking to the position of the air flow detection element 320, ensuring the cleanliness of the position of the air flow detection element 320 and protecting the air flow detection element 320 from being damaged.

[0124] In view of the fact that the above structure may affect the sensitivity of the air flow detection assembly to some extent, in some embodiments, the guide portion 2 can be provided with an air guide opening 203, and the air guide opening 203 is arranged in a spaced manner with the second air inlet 201.

[0125] Referring to Figure 9 and Figure 12 , the air guide opening 203 and the second air inlet 201 are both arranged on the air inlet side wall 22. In the axial direction of the air inlet support 10, the air guide opening 203 is opposite to the second air guide channel 420.

[0126] It can be understood that the aerosol generating device 100 provided by the embodiments of the present application can obtain better use experience under the action of the air inlet support 10, and can also improve the waste problem of condensate to some extent and improve the utilization rate of the aerosol forming substrate.

[0127] The above description of the various embodiments tends to emphasize the differences between the various embodiments, and the same or similar parts can be referred to each other, and for the sake of brevity, the same or similar parts will not be described herein.

[0128] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
