[0060] Figure 1 is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application, as Figure 1 shown, the aerosol generating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 is used to supply power to the atomizer 200. The atomizer 200 includes an atomization assembly 220, and the atomization assembly 220 is used to heat an aerosol matrix to form an aerosol. The atomization assembly 220 includes an atomization core 221.

[0061] The aerosol generating device has an air inlet passage 101a and an air outlet passage 101b, and the air outlet passage 101b is communicated with the air inlet passage 101a. The outlet of the air outlet passage 101b is opposite to the atomization core 221, so that the air flow in the air outlet passage 101b can flow towards the atomization core 221.

[0062] Some aerosol generating devices have a risk of liquid leakage. For example, during the product testing process of aerosol generating devices, such as high and low temperature cycle testing, negative pressure testing, etc., and during daily use, due to the pressure difference inside and outside the aerosol generating device or other environmental factors, the aerosol matrix stored in the atomizer 200 or the generated condensate may flow back through the air outlet airway 101b to the air inlet airway 101a and leak out of the aerosol generating device through the air inlet airway 101a, affecting the user experience.

[0063] Figure 2 It is a schematic structural diagram of a bracket of a power supply component provided by an embodiment of the present application, as Figure 2 shown, the bracket 101 includes a docking part 1011, and the docking part 1011 has a docking groove 1011a and a gas guiding groove 1011b. The docking groove 1011a is used for connecting with the atomizer 200.

[0064] Figure 3 It is a schematic structural diagram of a bracket of a power supply component provided by an embodiment of the present application, as Figure 3 shown, the docking part 1011 further has an air outlet airway 101b. The air outlet airway 101b communicates with the gas guiding groove 1011b and the docking groove 1011a.

[0065] Figure 4 It is a schematic cross-sectional view of a docking part of a bracket provided by an embodiment of the present application, as Figure 4 shown, the gas guiding groove 1011b is located outside the docking groove 1011a and at the bottom of the docking groove 1011a. The gas guiding groove 1011b has a first inner wall 101c close to the docking groove 1011a and a second inner wall 101d opposite to the first inner wall 101c. The docking part 1011 further has an air inlet airway 101a. Exemplarily, the outlet of the air inlet airway 101a may be located on the second inner wall 101d.

[0066] There are two support parts 1013 in the gas guiding groove 1011b. The support parts 1013 connect the first inner wall 101c and the second inner wall 101d, dividing the gas guiding groove 1011b into a first chamber A and two second chambers B. The first chamber A is located between the two second chambers B and is respectively communicated with the two second chambers B.

[0067] The outlet of the air inlet airway 101a and the inlet of the air outlet airway 101b are both located in the first chamber A.

[0068] By providing a docking groove 1011a and an air guiding groove 1011b at the docking portion 1011 of the holder 101, the docking groove 1011a is used to connect the atomizer 200. The air guiding groove 1011b is located at the bottom of the docking groove 1011a, and the two are connected through an air outlet airway 101b. The air guiding groove 1011b is also connected to the outside through an air inlet airway 101a, so that outside air can enter the air guiding groove 1011b via the air inlet airway 101a, and then enter the docking groove 1011a from the air guiding groove 1011b via the air outlet airway 101b. By providing two supporting portions 1013 in the air guiding groove 1011b, the air guiding groove 1011b is divided into a first chamber A and two second chambers B respectively communicating with the first chamber A by the two supporting portions 1013. The outlet of the air inlet airway 101a and the inlet of the air outlet airway 101b are both located in the first chamber A. When there is liquid (such as aerosol matrix, condensate) flowing into the first chamber A through the air outlet airway 101b, at least part of the liquid adhering to the inner wall of the air guiding groove 1011b can flow along the inner wall of the air guiding groove 1011b to the second chamber B and remain in the second chamber B, thereby reducing the risk of liquid leaking to the outside of the aerosol generating device through the air inlet airway 101a.

[0069] As an example, the inlet of the air outlet airway 101b can be located at the side wall of the supporting portion 1013 close to the air inlet airway 101a.

[0070] Arranging the inlet of the air outlet airway 101b on the side wall of the supporting portion 1013 makes it easier for the air flowing out of the air inlet airway 101a to directly enter the inlet of the air outlet airway 101b when flowing in the air guiding groove 1011b.

[0071] As Figure 4 shown, in this example, the docking portion 1011 has two air outlet airways 101b, and the outlet of the air inlet airway 101a is located between the inlets of the two air outlet airways 101b. The inlets of the two air outlet airways 101b are respectively located at the two supporting portions 1013.

[0072] The outlet of the air inlet airway 101a is arranged between the inlets of the two air outlet airways 101b, and the air flowing out of the air inlet airway 101a can flow to both sides and enter the two air outlet airways 101b respectively. By providing two air outlet airways 101b, one atomization core 221 can be arranged corresponding to each air outlet airway 101b, which can improve the atomization effect.

[0073] Referring again to Figure 4 , the second inner wall 101d also has an annular boss 1016, and the annular boss 1016 is arranged around the outlet of the air inlet airway 101a.

[0074] When there is liquid reaching near the outlet of the intake air passage 101a, the annular boss 1016 protruding from the second inner wall 101d can also block the further flow of this part of the liquid, preventing this part of the liquid from entering the intake air passage 101a and reducing the risk of liquid leakage.

[0075] In some examples, the inner wall of the annular boss 1016 can be aligned with the edge of the outlet of the intake air passage 101a. For example, the outlet of the intake air passage 101a is circular, the inner diameter of the annular boss 1016 is the same as the inner diameter of the outlet of the intake air passage 101a, and the center of the outlet of the intake air passage 101a is located on the axis of the annular boss 1016. By aligning the edge of the outlet of the intake air passage 101a to minimize the inner diameter of the annular boss 1016, the possibility of liquid directly dripping onto the inside of the annular boss 1016 is reduced.

[0076] As Figure 4 shown, the bottom of the docking groove 1011a has a protruding post 10111, and the outlet of the outlet air passage 101b is located at the end of the protruding post 10111.

[0077] By arranging the protruding post 10111 and arranging the outlet of the outlet air passage 101b at the end of the protruding post 10111, the outlet of the outlet air passage 101b can be made higher than the bottom of the docking groove 1011a, making it difficult for the aerosol matrix leaking into the docking groove 1011a to enter the outlet air passage 101b.

[0078] The second chamber B can also be used to accommodate a second adsorbent 227, such as a liquid-absorbing cotton. When there is liquid leaking from the outlet air passage 101b to the air guide groove 1011b, the second adsorbent 227 in the second chamber B can play a role in adsorbing and storing the liquid, preventing too much liquid from accumulating between the two support portions 1013.

[0079] In this example, the side wall of one of the second chambers B can also have a microphone hole 1011c. The outer side wall of the air guide groove 1011b can have a microphone mounting groove 102a, and the microphone hole 1011c can communicate the second chamber B and the microphone mounting groove 102a. During the suction process, the air pressure at the microphone hole 1011c will change, and the microphone 102 installed in the microphone mounting groove 102a can detect the change in air pressure to control the operation of the atomizer 200.

[0080] As an example, in the two second chambers B, the second adsorbent 227 can be arranged only in the second chamber B without the microphone hole 1011c, and the second chamber B with the microphone hole 1011c is not arranged with the second adsorbent 227, which can ensure the smoothness of the microphone hole 1011c and avoid affecting the sensitivity of the microphone 102.

[0081] The support portion 1013 is arranged in the air guide groove 1011b, connecting the first inner wall 101c and the second inner wall 101d of the air guide groove 1011b, and can also improve the structural strength of the docking portion 1011.

[0082] Referring to Figure 3 , the interior of the support portion 1013 may further have an electrode jack 1013a, and the electrode jack 1013a can penetrate through the air guide groove 1011b. The bracket 101 may further include a battery accommodating portion 1014, and the battery accommodating portion 1014 is connected to the docking portion 1011. The battery accommodating portion 1014 is located on the side of the air guide groove 1011b away from the docking groove 1011a. The battery accommodating portion 1014 has a battery accommodating groove for accommodating a battery. The electrode jack 1013a communicates the docking groove 1011a and the battery accommodating groove. The electrode jack 1013a is used for placing an electrode 2231 to connect the atomizer 200 and the battery 104.

[0083] Referring to Figure 2 or Figure 3 As shown, the support portion 1013 has a notch 1013c, and the notch 1013c communicates the first chamber A and the second chamber B.

[0084] Providing the notch 1013c in the support portion 1013 enables liquid to flow from the first chamber A into the second chamber B via the notch 1013c. The notch 1013c does not affect the integrity of the overall structure of the support portion 1013, and maintains communication while keeping the first chamber A and the second chamber B relatively independent.

[0085] Exemplarily, the notch 1013c may be located at the end of the support portion 1013, which facilitates the machining of the notch 1013c.

[0086] Figure 5 is a schematic structural diagram of a bracket provided by an embodiment of the present application. As Figure 5 shown, the bracket may further include a sealing plate 1015. The sealing plate 1015 may be located in the air guide groove 1011b, and the sealing plate 1015 is in sealing cooperation with the inner wall of the air guide groove 1011b. The sealing plate 1015 may abut against the end of the support portion 1013, using the support portion 1013 to limit the sealing plate 1015, and does not affect the notch 1013c communicating the first chamber A and the second chamber B.

[0087] In some examples, the notch 1013c of one of the two support portions 1013 is close to the first inner wall 101c; the notch 1013c of the other of the two support portions 1013 is close to the second inner wall 101d.

[0088] The notch 1013c is close to the first inner wall 101c, and the distance from the notch 1013c to the first inner wall 101c is less than the distance from the notch 1013c to the second inner wall 101d; the notch 1013c is close to the second inner wall 101d, and the distance from the notch 1013c to the second inner wall 101d is less than the distance from the notch 1013c to the first inner wall 101c.

[0089] During the processes of testing, using, carrying, etc. of the aerosol generating device, it is usually not always in an upright state (the mouthpiece 3011 is vertically upward), so the liquid may adhere to the first inner wall 101c and flow along the first inner wall 101c to the second chamber B, or may adhere to the second inner wall 101d and flow from the second inner wall 101d to the second chamber B. By arranging the notch 1013c of one support portion 1013 close to the first inner wall 101c and the notch 1013c of the other support portion 1013 close to the second inner wall 101d, no matter whether the aerosol generating device is in an upright or inverted state, the liquid can always enter the second chamber B through one notch 1013c.

[0090] As an example, the notch 1013c of one support portion 1013 may be located at the edge of the support portion 1013 close to the first inner wall 101c; the notch 1013c of the other support portion 1013 may be located at the edge of the support portion 1013 close to the second inner wall 101d, so that the liquid can more easily enter the second chamber B through the notch 1013c.

[0091] As Figure 4 shown, the bracket 101 may further include a barrier member 1017, and the barrier member 1017 is located in the first chamber A. The outlet of the intake airway 101a is on one side of the barrier member 1017, and the inlet of the outlet airway 101b is on the other side of the barrier member 1017. The barrier member 1017 has ventilation holes 1017a communicating the two sides.

[0092] In addition to possibly flowing into the second chamber B through the notch 1013c, the liquid flowing into the first chamber A from the inlet of the outlet airway 101b may also flow towards the outlet of the intake airway 101a. By arranging the barrier member 1017 in the first chamber A and using the barrier member 1017 to separate the inlet of the outlet airway 101b and the outlet of the intake airway 101a, the risk of the liquid flowing into the intake airway 101a can be greatly reduced. The ventilation holes 1017a ensure that the air flow in the intake airway 101a can smoothly enter the outlet airway 101b.

[0093] As an example, the bracket 101 may include two barrier members 1017, one barrier member 1017 is located between the outlet of the intake airway 101a and the inlet of one outlet airway 101b, and the other barrier member 1017 is located between the outlet of the intake airway 101a and the inlet of the other outlet airway 101b.

[0094] By arranging two barrier members 1017 to separate the outlet of the intake air passage 101a from both of the two outlet air passages 101b, the liquid flowing into the first chamber A from the two intake air passages 101a can be blocked, further reducing the risk of liquid leakage.

[0095] The vent hole 1017a can be located at the middle position of the barrier member 1017. For example, the distances from the vent hole 1017a to the first inner wall 101c and the second inner wall 101d can be equal. This makes it difficult for the liquid to pass through the barrier member 1017 via the vent hole 1017a regardless of whether the aerosol generating device is in an upright or inverted state.

[0096] In some examples, the inlet of the outlet air passage 101b can be arranged opposite to the vent hole 1017a.

[0097] The inlet of the outlet air passage 101b is arranged opposite to the vent hole 1017a, making the air flowing from the vent hole 1017a to the outlet air passage 101b more likely to directly enter the inlet of the outlet air passage 101b, and can reduce the resistance during the user's suction process.

[0098] In some examples, the surface of the barrier member 1017 has at least one of protrusions and depressions.

[0099] The protrusions and depressions can increase the surface area of the barrier member 1017, so that more liquid can adhere to the surface of the barrier member 1017. The liquid adhering to the inner wall of the air guiding groove 1011b flows to the barrier member 1017, can adhere to the surface of the barrier member 1017, remain between adjacent protrusions, or remain in the depressions, increasing the difficulty for the liquid to flow along the surface of the barrier member 1017 into the vent hole 1017a and cross the barrier member 1017.

[0100] Figure 6 It is a schematic structural diagram of a barrier member provided by an embodiment of the present application. As Figure 6 shown, as an example, the surface of the barrier member 1017 has a plurality of first ridges 10171, and at least some of the plurality of first ridges 10171 intersect each other.

[0101] The first ridges 10171 increase the surface area of the barrier member 1017, and the first ridges 10171 intersect each other to form a groove on the surface of the barrier member 1017 that can accommodate liquid.

[0102] Some of the plurality of first ridges 10171 can be parallel to each other, and some of the other first ridges 10171 can be perpendicular to each other.

[0103] As Figure 6As shown, on one side of the barrier member 1017 close to the first inner wall 101c and on one side close to the second inner wall 101d, there are respectively card slots 1017b. Refer to Figure 4 As shown, the first inner wall 101c and the second inner wall 101d have second convex ribs 10172, and the second convex ribs 10172 are located in the card slots 1017b.

[0104] Through the mutual cooperation of the second convex ribs 10172 and the card slots 1017b, the barrier member 1017 can be stably installed in the air guide groove 1011b. The second convex ribs 10172 are snapped into the card slots 1017b. The contact surface formed by the second convex ribs 10172 and the barrier member 1017 is relatively large, with good sealing performance, and it is also difficult for liquid to pass through the gap between the second convex ribs 10172 and the card slots 1017b to cross over the barrier member 1017.

[0105] In some examples, the barrier member 1017 can be an elastic member, such as a silicone member or a rubber member. The elastic barrier member 1017 can better contact the second convex ribs 10172, the first inner wall 101c, and the second inner wall 101d under the action of its own elasticity, and a certain pressure can also be generated on the contact surface, thereby improving the sealing performance and preventing liquid from crossing over the barrier member 1017 through the gap between the barrier member 1017 and the inner wall of the air guide groove 1011b.

[0106] Figure 7 is a schematic diagram of the internal structure of the air guide groove of a bracket provided by an embodiment of the present application. As shown in Figure 7 As shown, the second inner wall 101d can also have third convex ribs 10173, and the third convex ribs 10173 are located on the side of the barrier member 1017 away from the outlet of the intake air passage 101a.

[0107] When the liquid flowing into the first chamber A through the outlet air passage 101b flows in the direction of the outlet of the intake air passage 101a, it needs to cross over the third convex ribs 10173 along the surface of the second inner wall 101d. The setting of the third convex ribs 10173 increases the length of the path, making it more difficult for the liquid to flow into the outlet of the intake air passage 101a. It also increases the area of the second inner wall 101d, enabling more liquid to adhere to and remain in the area between the support portion 1013 and the barrier member 1017.

[0108] As an example, there are multiple third convex ribs 10173, and the multiple third convex ribs 10173 are arranged at intervals in the direction away from the barrier member 1017.

[0109] Setting multiple third convex ribs 10173 can further increase the length of the path and further increase the surface area of the second inner wall 101d.

[0110] A plurality of third convex ridges 10173 are arranged at intervals in a direction away from the barrier member 1017. That is to say, the third convex ridges 10173 are arranged parallel or substantially parallel to the barrier member 1017. The gaps between adjacent third convex ridges 10173 can also play a role in guiding the flow. Under the guidance of the gaps between adjacent third convex ridges 10173, the liquid is more likely to flow along the gaps. Only when the liquid level in the gaps exceeds the third convex ridges 10173 can the liquid possibly flow further in the direction closer to the outlet of the intake air passage 101a. And the liquid flowing along the gap to the end of the third convex ridge 10173 can also easily enter the second chamber B through the notch 1013c.

[0111] Figure 8 is a schematic internal structure diagram of the air guiding groove of a bracket provided by an embodiment of the present application. As Figure 8 shown, in the bracket 101, a flow guiding convex ridge 1012 is connected to the first inner wall 101c. The flow guiding convex ridge 1012 is opposite to the outlet of the intake air passage 101a and is used to guide the air flow flowing out of the outlet of the intake air passage 101a to both sides of the flow guiding convex ridge 1012.

[0112] By providing the flow guiding convex ridge 1012 on the first inner wall 101c of the air guiding groove 1011b, the outlet of the intake air passage 101a and the flow guiding convex ridge 1012 are opposite to each other, and the inlets of the two outlet air passages 101b are located on both sides of the flow guiding convex ridge 1012, so that the air flow guided to both sides of the flow guiding convex ridge 1012 can enter the two outlet air passages 101b respectively. Under the guiding action of the flow guiding convex ridge 1012, the air flow can enter the two outlet air passages 101b more stably, making the air flow rate in the outlet air passage 101b stable with small fluctuations, avoiding the situation that the air flow rate in one outlet air passage 101b is too large and the air flow rate in the other outlet air passage 101b is too small, making the atomization effect stable, and avoiding the atomization core 221 from burning and producing a burnt smell due to too small air flow rate.

[0113] As Figure 8 shown, along the direction in which the flow guiding convex ridge 1012 protrudes from the first inner wall 101c, the width of the flow guiding convex ridge 1012 gradually decreases.

[0114] The direction in which the flow guiding convex ridge 1012 protrudes from the first inner wall 101c is also the direction from the first inner wall 101c to the second inner wall 101d. The gradually decreasing width of the flow guiding convex ridge 1012 makes the side wall 1012a of the flow guiding convex ridge 1012 inclined relative to the first inner wall 101c, and the inclined direction enables the air flow rushing from the intake air passage 101a to the flow guiding convex ridge 1012 to gradually change the flow direction along the side wall 1012a of the flow guiding convex ridge 1012 and flow in the direction where the inlet of the outlet air passage 101b is located.

[0115] In some examples, the cross-section of the flow guiding rib 1012 can be triangular, that is, the two side walls 1012a of the flow guiding rib 1012 can intersect.

[0116] In other possible implementations, the cross-section of the flow guiding rib 1012 can be quadrilateral, such as trapezoidal, that is, the two side walls 1012a of the flow guiding rib 1012 do not intersect.

[0117] In some examples, the side wall 1012a of the flow guiding rib 1012 close to the barrier 1017 is a concave surface.

[0118] In this example, the side wall 1012a of the flow guiding rib 1012 close to the barrier 1017 is recessed inward, so that the cross-section of the flow guiding rib 1012 is a curvilinear triangle, and the two sides of the triangle are concave curves. Setting the side wall 1012a of the flow guiding rib 1012 as a concave surface is more conducive to the side wall 1012a guiding the airflow to change the flow direction and making the air flow rate more stable.

[0119] In other examples, the cross-section of the flow guiding rib 1012 can also be a curvilinear trapezoid, and the two waists of the trapezoid are concave curves.

[0120] In some possible implementations, the side wall 1012a of the flow guiding rib 1012 close to the barrier 1017 can also be a plane for convenient processing.

[0121] In some examples, the side wall 1012a of the flow guiding rib 1012 close to the barrier 1017 is tangent to the first inner wall 101c. For example, the connection between the side wall 1012a and the first inner wall 101c is connected by a fillet. Another example is that the side wall 1012a is a curved surface, and the curved surface is tangent to the first inner wall 101c at the connection with the first inner wall 101c.

[0122] The airflow flowing out of the intake air passage 101a acts on the side wall 1012a of the flow guiding rib 1012 and flows along the side wall 1012a of the flow guiding rib 1012, and the flow direction gradually changes. The side wall 1012a of the flow guiding rib 1012 is tangent to the first inner wall 101c, so that when the airflow reaches the connection between the side wall 1012a of the flow guiding rib 1012 and the first inner wall 101c, it can transition more smoothly to flow along the first inner wall 101c, making the airflow on both sides of the flow guiding rib 1012 in the air guiding groove 1011b more stable.

[0123] As an example, the side wall 1012a of the flow guiding rib 1012 close to one barrier 1017 is symmetric with the side wall 1012a close to the other barrier 1017, and the symmetry plane m passes through the geometric center of the outlet of the intake air passage 101a.

[0124] That is, the diversion rib 1012 is a face-symmetric structure, and the geometric center of the outlet of the intake air passage 101a is located on the symmetry plane m of the diversion rib 1012. When the air flow flowing out from the outlet of the intake air passage 101a acts on the diversion rib 1012, half of the air flow can flow along one side wall 1012a of the diversion rib 1012 to the inlet of one outlet air passage 101b, and the other half of the air flow can flow along the other side wall 1012a of the diversion rib 1012 to the inlet of the other outlet air passage 101b, so that the air flow rates in the two outlet air passages 101b are quite equal.

[0125] The shape of the outlet of the intake air passage 101a can be a face-symmetric figure, and the symmetry plane of the outlet of the intake air passage 101a can coincide with the symmetry plane m of the diversion rib 1012. Exemplarily, the outlet of the intake air passage 101a can be rectangular, circular or oval.

[0126] In other possible implementation manners, the geometric center of the outlet of the intake air passage 101a can also be located on one side of the symmetry plane m of the diversion rib 1012, so that when the air flow flowing out from the outlet of the intake air passage 101a acts on the diversion rib 1012, the air flow rates flowing to both sides of the diversion rib 1012 are not equal. By adjusting the distance by which the geometric center of the outlet of the intake air passage 101a deviates from the symmetry plane m of the diversion rib 1012, the ratio of the air flow rates in the two outlet air passages 101b can be adjusted so that the ratio of the air flow rates in the two outlet air passages 101b meets specific design requirements. For example, the air flow rates in the two outlet air passages 101b are 1:2.

[0127] Figure 9 It is a schematic internal structure diagram of the air guiding groove of a bracket provided by an embodiment of the present application. As Figure 9 shown, in this bracket 101, a liquid baffle 10131 is further connected to the side wall of the support portion 1013 close to the barrier member 1017, and the liquid baffle 10131 is located on the side close to the second inner wall 101d at the inlet of the outlet air passage 101b.

[0128] By providing the liquid baffle 10131 on the support portion 1013, the liquid flowing out from the inlet of the outlet air passage 101b can be blocked, so that the liquid adheres to the surface of the liquid baffle 10131, preventing the liquid from dripping onto the second inner wall 101d.

[0129] In some examples, a liquid storage tank 10132 is formed by the side of the liquid baffle 10131 close to the first inner wall 101c and the side wall of the support portion 1013.

[0130] The liquid baffle 10131 protrudes from the side wall of the support portion 1013, and the surface of the liquid baffle 10131 provides a relatively limited space for liquid attachment. When there is a large amount of liquid, some liquid cannot attach to the surface of the liquid baffle 10131 and will drip over the liquid baffle 10131 onto the second inner wall 101d. By enclosing a liquid storage tank 10132 with the liquid baffle 10131 and the support portion 1013, a larger accommodation space can be formed to hold more liquid.

[0131] As an example, as Figure 9 shown, the side of the liquid baffle 10131 close to the first inner wall 101c has a retaining edge 10133, and the retaining edge 10133 is spaced apart from the side wall of the support portion 1013.

[0132] The surface of the retaining edge 10133 close to the support portion 1013, the surface of the part of the liquid baffle 10131 located between the retaining edge 10133 and the support portion 1013, and the surface of the support portion 1013 close to the retaining edge 10133 enclose the liquid storage tank 10132, and the retaining edge 10133 blocks the liquid from passing over the liquid baffle 10131.

[0133] Figure 10 is a schematic internal structure diagram of the air guide groove of a bracket provided by an embodiment of the present application. As Figure 10 shown, in the bracket 101, the liquid baffle 10131 can be inclined towards the first inner wall 101c, so that the distance from the edge of the liquid baffle 10131 close to the first inner wall 101c to the first inner wall 101c is less than the distance from the edge of the liquid baffle 10131 connected to the support portion 1013 to the first inner wall 101c. A V-shaped liquid storage tank 10132 is formed between the liquid baffle 10131 and the support portion 1013 to hold the liquid flowing out of the air outlet channel 101b.

[0134] In other possible implementation manners, the liquid baffle 10131 can have both a retaining edge 10133 and be inclined towards the first inner wall 101c to further increase the volume of the liquid storage tank 10132.

[0135] Figure 11 is a schematic structural diagram of a power supply assembly provided by an embodiment of the present application. As Figure 11 shown, the power supply assembly can include a battery 104 and any one of the brackets 101 as Figures 2 to 10 shown, and the battery 104 is located at the bottom of the docking portion 1011.

[0136] As an example, the power supply assembly 100 can further include a circuit board 103 and a microphone 102. The outer side wall of the docking portion 1011 can have a microphone mounting groove 102a, the circuit board 103 is located on one side of the bracket 101, the microphone 102 is located in the microphone mounting groove 102a, and the microphone 102 is connected to the circuit board 103.

[0137] As shown Figure 11 in the figure, the power supply assembly 100 further includes a display panel 105, which is located on the side of the circuit board 103 away from the microphone 102, and the display panel 105 is electrically connected to the circuit board 103.

[0138] By arranging the display panel 105 on one side of the circuit board 103 so that the display panel 105 and the circuit board 103 are arranged in a parallel or approximately parallel manner, space can be saved and the structure of the power supply assembly can be made more compact.

[0139] Figure 12 is a schematic structural diagram of a power supply assembly provided by an embodiment of the present application. As Figure 12 shown in the figure, the power supply assembly 100 may further include a first adsorbent 228, which is located in the docking groove 1011a, and the outlet of the air outlet airway 101b is higher than the surface of the first adsorbent 228 away from the bottom of the docking groove 1011a.

[0140] The first adsorbent 228 arranged in the docking groove 1011a can adsorb the aerosol matrix leaked into the docking groove 1011a. By setting the outlet of the air outlet airway 101b higher than the surface of the first adsorbent 228 away from the bottom of the docking groove 1011a, the aerosol matrix leaked into the docking groove 1011a will be preferentially absorbed by the first adsorbent 228, increasing the difficulty of the aerosol matrix leaking into the air outlet airway 101b.

[0141] Exemplarily, the first adsorbent 228 may be absorbent cotton.

[0142] Figure 13 is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application. As Figure 13 shown in the figure, the aerosol generating device includes an atomizer 200 and a power supply assembly 100. The power supply assembly 100 is connected to the atomizer 200. The power supply assembly 100 is used to supply power to the atomizer 200. The power supply assembly 100 may be Figure 11 or Figure 12 the power supply assembly 100 shown in the figure.

[0143] The atomizer 200 includes a liquid storage assembly 210 and an atomization assembly 220. The liquid storage assembly 210 is used to store the aerosol matrix. The atomization assembly 220 may include two atomization cores 221.

[0144] The liquid storage assembly 210 may include a liquid storage housing 211, and a liquid storage is formed inside the liquid storage housing 211 for accommodating the aerosol matrix. The liquid storage assembly 210 may further include a base 212, and the base 212 may be fixedly connected or detachably connected to the liquid storage housing 211.

[0145] Figure 14 It is a schematic internal structure diagram of an aerosol generating device provided by an embodiment of the present application. As Figure 14 shown, an atomization chamber 200a is formed in the base 212, and the atomization assembly 220 can be located in the atomization chamber 200a. The atomization assembly 220 is used to heat the aerosol matrix to form an aerosol.

[0146] In some examples, the liquid storage assembly 210 may further include a liquid storage member. For example, the liquid storage member can be a liquid storage cotton, and the liquid storage cotton adsorbs / soaks the aerosol matrix.

[0147] The base 212 further has an exhaust passage 212a. One end of the exhaust passage 212a is communicated with the atomization chamber 200a, and the other end is used to communicate with the mouthpiece 3011.

[0148] The base 212 further has a liquid inlet passage 212b. The liquid inlet passage 212b communicates the atomization chamber 200a and the liquid storage chamber. The aerosol matrix can flow through the liquid inlet passage 212b to the atomization core 221, so that the atomization core 221 is in a wet state. When the atomization core 221 works, it heats the aerosol matrix and releases the aerosol. During the suction process, the aerosol enters the mouthpiece 3011 through the exhaust passage 212a.

[0149] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Since the power supply assembly 100 and the atomizer 200 are detachably connected, it is convenient to replace the atomizer 200.

[0150] In some other examples, the power supply assembly 100 and the atomizer 200 can be fixedly connected. For example, the housing part of the power supply assembly 100 and the liquid storage housing 211 of the atomizer 200 are of an integral structure.

[0151] Exemplarily, the power supply assembly 100 may include a housing 106, and a bracket 101 is located in the housing 106. The housing 106 can be snap-connected to the liquid storage housing 211.

[0152] As Figure 14 shown, a light-transmitting plate 1061 can also be installed outside the housing 106. The light-transmitting plate 1061 can be arranged opposite to the display panel 105, so that the picture displayed on the display panel 105 can be normally seen from outside the housing 106.

[0153] A key cap 1062 can also be installed outside the housing 106. The key cap 1062 can be connected to the button on the surface of the circuit board 103 to facilitate user operation.

[0154] The base 212 is located in the docking groove 1011a. A first adsorbent 228 is arranged between the base 212 and the bottom of the docking groove 1011a. The first adsorbent 228 is used to absorb the aerosol matrix that may leak between the base 212 and the bottom of the docking groove 1011a.

[0155] A third adsorbent 226 can also be provided in the base 212. The third adsorbent 226 can be located between the base 212 and the bottom of the docking groove 1011a. The third adsorbent 226 can also be absorbent cotton.

[0156] As Figure 14 shown, the atomization core includes a liquid guiding member 222 and a heating member 223. The heating member 223 is located on the side of the liquid guiding member 222 away from the liquid inlet channel 212b. The aerosol generating device further includes an electrode 2231. The electrode 2231 is inserted into the bottom of the docking groove 1011a. One end of the electrode 2231 is located in the atomization cavity 200a and abuts against the heating member 223. The other end of the electrode 2231 is used to connect to the battery 104.

[0157] The liquid guiding member 222 absorbs the aerosol matrix flowing out of the liquid inlet channel 212b and temporarily stores it in the liquid guiding member 222, making the liquid guiding member 222 in a wet state. The heating member 223 heats the liquid guiding member 222 to atomize the aerosol matrix in the liquid guiding member 222 to form an aerosol. By arranging the heating member 223 on the side of the liquid guiding member 222 away from the liquid inlet channel 212b and the electrode 2231 abutting against the side of the heating member 223 away from the liquid guiding member 222, it can play a role in strengthening the atomization core, making the atomization core stably installed and preventing the aerosol matrix in the liquid inlet channel 212b from directly leaking into the atomization cavity 200a.

[0158] Referring to Figure 14 shown, the atomizer 200 of the aerosol generating device can further include a seal 229. The seal 229 is located on the side of the base 212 away from the docking portion 1011. The seal 229 forms a seal with the inner side wall of the liquid storage housing 211 to improve the sealing performance of the liquid storage.

[0159] Figure 13 and Figure 14 The structure of the atomizer 200 in the aerosol generating device shown is only an example. In other possible implementation manners, the structure of the atomizer 200 of the aerosol generating device can also be different from that shown in the figure.

[0160] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included within the protection scope of the present application.
