[0002] Common aerosol generating devices include an atomizer and a power supply unit, with the atomizer connected to the power supply unit. During operation, the power supply unit supplies power to the atomizer.

[0003] The power supply assembly includes a bracket with an air intake channel and an air outlet channel. The air intake channel connects the bracket to the outside world, and the air outlet channel connects to the atomizer to guide the airflow to the vicinity of the atomizer core.

[0004] Currently, some aerosol generation devices have been found to experience leakage of aerosol matrix or condensate during product testing or normal use. Utility Model Content

[0005] This application provides a support for a power supply component, a power supply component, and an aerosol generation device, which can reduce the risk of leakage of the aerosol matrix. The technical solution is as follows:

[0006] In a first aspect, embodiments of this application provide a bracket for a power supply component. The bracket includes a docking portion, which has a docking groove, a venting groove, an air inlet duct, and at least one air outlet duct. The air outlet duct connects the venting groove and the docking groove.

[0007] The air guide groove is located outside the docking groove and at the bottom of the docking groove;

[0008] The air guide groove has a first inner wall close to the docking groove and a second inner wall opposite to the first inner wall, and the outlet of the air intake passage is located on the second inner wall;

[0009] The inner wall of the air guide groove is provided with a protruding ridge, which is located between the outlet of the air inlet channel and the inlet of the air outlet channel, and is located at least one of the first inner wall and the second inner wall.

[0010] In some examples, the protrusion includes a first protrusion and a second protrusion, the first protrusion being located on the first inner wall and the second protrusion being located on the second inner wall.

[0011] In some examples, the side of the first ridge away from the first inner wall is opposite to the side of the second ridge away from the second inner wall.

[0012] In some examples, the second inner wall also has an annular boss arranged around the outlet of the air intake duct.

[0013] In some examples, the distance from the annular boss to the first inner wall is greater than the height of the ridge located on the first inner wall.

[0014] In some examples, the docking portion has two air outlets, with the outlet of the air inlet located between the inlets of the two air outlets.

[0015] In some examples, the air guide groove also has two support parts, which connect the first inner wall and the second inner wall, and the outlet of the air intake passage and the protruding ridge are located between the two support parts;

[0016] The inlet of the air outlet is located on the side wall of the support near the protruding ridge.

[0017] In some examples, the side of the support portion away from the protruding ridge forms a receiving cavity with the inner wall of the air guide groove, and the portion of the air guide groove located between the two supports is in communication with the receiving cavity.

[0018] In some examples, the bottom of the docking groove has a protrusion, and the outlet of the air outlet is located at the end of the protrusion.

[0019] Secondly, embodiments of this application also provide a power supply component, which includes a battery and a bracket as described in the first aspect.

[0020] In some examples, the power supply assembly further includes a first adsorption element located in the docking groove, and the outlet of the air outlet is above the surface of the first adsorption element away from the bottom of the docking groove.

[0021] Thirdly, embodiments of this application also provide an aerosol generating device, the aerosol generating device including an atomizer and a power supply component as described in the second aspect, the power supply component being connected to the atomizer and used to supply power to the atomizer.

[0022] The beneficial effects of the technical solutions provided in this application include at least the following:

[0023] By incorporating a docking groove and an air guide groove at the joint of the support, the docking groove connects the atomizer, and the air guide groove is located at the bottom of the docking groove. The two are connected via an outlet air passage, and the air guide groove also connects to the outside environment via an inlet air passage. This allows outside air to enter the air guide groove via the inlet air passage, and then from the air guide groove through the outlet air passage into the docking groove. By arranging protrusions on the first and / or second inner walls, located between the outlet of the inlet air passage and the inlet of the outlet air passage, the outlet of the inlet air passage and the inlet of the outlet air passage can be separated. Liquid flowing back from the outlet air passage to the air guide groove adheres to the inner wall of the air guide groove. As it gradually flows along the inner wall of the air guide groove towards the outlet of the inlet air passage, it is blocked by the protrusions, making it difficult for the liquid to flow into the inlet air passage. This reduces the risk of aerosol matrix or condensate leaking outside the aerosol generation device via the inlet air passage. Attached Figure Description

[0044] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 supplies power to the atomizer 200. The atomizer 200 includes an atomizing component 220, which is used to heat the aerosol matrix to form an aerosol. The atomizing component 220 includes an atomizing core 221.

[0045] The aerosol generating device has an inlet airway 101a and an outlet airway 101b, with the outlet airway 101b connected to the inlet airway 101a. The outlet of the outlet airway 101b is opposite to the atomizing core 221, allowing the airflow in the outlet airway 101b to flow towards the atomizing core 221.

[0046] During product testing of the aerosol generating device, such as high and low temperature cycle testing and negative pressure testing, as well as during daily use, the aerosol matrix stored in the atomizer 200 or the generated condensate may flow back through the outlet air passage 101b to the inlet air passage 101a and leak out of the aerosol generating device from the inlet air passage 101a, affecting the user experience.

[0047] Figure 2 This is a schematic diagram of the structure of a power supply component bracket provided in an embodiment of this application, as shown below. Figure 2 As shown, the bracket 101 includes a docking part 1011, which has a docking groove 1011a and an air guide groove 1011b. The docking groove 1011a is used to connect with the atomizer 200.

[0048] Figure 3 This is a schematic diagram of the structure of a power supply component bracket provided in an embodiment of this application, as shown below. Figure 3 As shown, the docking part 1011 also has an air outlet duct 101b. The air outlet duct 101b connects the air guide groove 1011b and the docking groove 1011a.

[0049] Figure 4 This is a cross-sectional schematic diagram of the docking portion of a bracket provided in an embodiment of this application, as shown below. Figure 4 As shown, the air guide groove 1011b is located outside the docking groove 1011a and at the bottom of the docking groove 1011a. The air guide groove 1011b has a first inner wall 101c near the docking groove 1011a and a second inner wall 101d opposite to the first inner wall 101c. The docking part 1011 also has an air intake passage 101a, the outlet of which is located on the second inner wall 101d.

[0050] The inner wall of the air guide groove 1011b is provided with a protruding ridge 1012, which is located between the outlet of the air intake duct 101a and the inlet of the air outlet duct 101b, and is located at least one of the first inner wall 101c and the second inner wall 101d.

[0051] For example, in some examples, the protrusion 1012 may be located on the first inner wall 101c; in other examples, the protrusion 1012 may be located on the second inner wall 101d.

[0052] As an example, both the first inner wall 101c and the second inner wall 101d are provided with protruding ridges 1012.

[0053] A docking groove 1011a and an air guide groove 1011b are provided in the docking portion 1011 of the bracket 101. The docking groove 1011a is used to connect the atomizer 200, and the air guide groove 1011b is located at the bottom of the docking groove 1011a. The two are connected through the air outlet duct 101b. The air guide groove 1011b is also connected to the outside through the air inlet duct 101a, so that outside air can enter the air guide groove 1011b through the air inlet duct 101a, and then enter the docking groove 1011a from the air guide groove 1011b through the air outlet duct 101b. By arranging a protruding rib 1012 on the first inner wall 101c and / or the second inner wall 101d, the protruding rib 1012 is located between the outlet of the air inlet duct 101a and the inlet of the air outlet duct 101b, which can separate the outlet of the air inlet duct 101a and the inlet of the air outlet duct 101b. The liquid flowing back from the outlet air passage 101b to the guide air groove 1011b adheres to the inner wall of the guide air groove 1011b. As it gradually flows along the inner wall of the guide air groove 1011b towards the outlet of the inlet air passage 101a, it is blocked by the protruding ridge 1012, making it difficult for the liquid to flow into the inlet air passage 101a. This reduces the risk of aerosol matrix or condensate leaking out of the aerosol generating device through the inlet air passage 101a.

[0054] As an example, such as Figure 4 As shown, the docking part 1011 has two air outlet passages 101b, and the outlet of the air inlet passage 101a is located between the inlets of the two air outlet passages 101b.

[0055] By setting two air outlet channels 101b, an atomizing core 221 can be arranged for each air outlet channel 101b, which can improve the atomization effect.

[0056] A protruding rib 1012 can be arranged between the outlet of the air intake duct 101a and the inlet of each air outlet duct 101b, so that the liquid flowing out of each air outlet duct 101b will be blocked by the protruding rib 1012 when it flows along the inner wall of the air guide groove 1011b to the outlet of the air intake duct 101a.

[0057] like Figure 4 As shown, the protruding ridge 1012 may include a first protruding ridge 10121 and a second protruding ridge 10122. The first protruding ridge 10121 is located on the first inner wall 101c, and the second protruding ridge 10122 is located on the second inner wall 101d.

[0058] Liquid flowing from the outlet air passage 101b into the air guide groove 1011b may adhere to the surface of the first inner wall 101c and flow along the first inner wall 101c towards the outlet of the intake air passage 101a, or it may adhere to the surface of the second inner wall 101d and flow along the second inner wall 101d towards the outlet of the intake air passage 101a. By arranging a first protruding rib 10121 on the first inner wall 101c and a second protruding rib 10122 on the second inner wall 101d, the flow of liquid adhering to the inner wall of the air guide groove 1011b can be better blocked, further reducing the risk of leakage.

[0059] like Figure 4 As shown, the side of the first protruding ridge 10121 away from the first inner wall 101c is opposite to the side of the second protruding ridge 10122 away from the second inner wall 101d. That is, the top of the first protruding ridge 10121 is opposite to the top of the second protruding ridge 10122.

[0060] By arranging the tops of the first convex ridge 10121 and the second convex ridge 10122 opposite to each other, the risk of leakage can be further reduced.

[0061] Liquid adhering to the inner wall of the air guide groove 1011b flows to the protrusion 1012 and flows along the surface of the protrusion 1012, with the possibility of dripping. With the tops of the first protrusion 10121 and the second protrusion 10122 arranged opposite each other, when liquid adhering to the first inner wall 101c flows to the location of the first protrusion 10121 and drips from the first protrusion 10121 to the second inner wall 101d, it is more likely to drip onto the outer side of the second protrusion 10122, that is, the side of the second protrusion 10122 away from the outlet of the air intake duct 101a; similarly, when liquid adhering to the second inner wall 101d flows to the location of the second protrusion 10122 and drips from the second protrusion 10122 to the first inner wall 101c, it is more likely to drip onto the outer side of the first protrusion 10121, that is, the side of the first protrusion 10121 away from the outlet of the air intake duct 101a.

[0062] During testing, use, and carrying, the aerosol generating device is not usually kept in an upright position (with the nozzle 3011 facing upwards) at all times. Therefore, liquid may drip from the first inner wall 101c to the second inner wall 101d, or from the second inner wall 101d to the first inner wall 101c.

[0063] like Figure 4 As shown, the second inner wall 101d also has an annular boss 1016, which is arranged around the outlet of the air intake duct 101a.

[0064] When liquid crosses the protrusion 1012 and reaches the side of the protrusion 1012 near the outlet of the air intake passage 101a, the annular protrusion 1016 protruding from the second inner wall 101d can also block the further flow of this liquid, preventing this liquid from entering the air intake passage 101a and reducing the risk of leakage.

[0065] In some examples, the inner wall of the annular boss 1016 can be aligned with the edge of the outlet of the intake duct 101a. For example, the outlet of the intake duct 101a is circular, the inner diameter of the annular boss 1016 is the same as the inner diameter of the outlet of the intake duct 101a, and the center of the outlet of the intake duct 101a is located on the axis of the annular boss 1016. By aligning the edge of the outlet of the intake duct 101a, the inner diameter of the annular boss 1016 is minimized, reducing the possibility of liquid dripping directly onto the inside of the annular boss 1016.

[0066] like Figure 4 As shown, the distance from the annular boss 1016 to the first inner wall 101c is greater than the height of the protruding ridge 1012 located on the first inner wall 101c, that is, greater than the height of the first protruding ridge 10121.

[0067] The protruding ridge 1012 protrudes from the inner wall of the air guide groove 1011b, and the height of the protruding ridge 1012 is the height by which the protruding ridge 1012 protrudes relative to the inner wall of the air guide groove 1011b. The height of the first protruding ridge 10121 is the height by which the first protruding ridge 10121 protrudes relative to the first inner wall 101c.

[0068] During the suction process, the airflow flows outward from the outlet of the inlet channel 101a. Within the annular protrusion 1016, the airflow direction is towards the first inner wall 101c. The first protruding ridges 10121 on both sides affect the flow of air flowing out of the annular protrusion 1016 towards the inlets of the outlet channels 101b on both sides. By making the distance from the annular protrusion 1016 to the first inner wall 101c greater than the height of the first protruding ridge 10121, the influence of the first protruding ridge 10121 on the airflow can be reduced, making it easier for the gas flowing out of the annular protrusion 1016 to flow to both sides.

[0069] The height of the annular protrusion 1016 can be greater than the height of the second protrusion 10122, which can reduce the impact of the second protrusion 10122 on the airflow.

[0070] like Figure 4 As shown, the air guide groove 1011b also has two support portions 1013, which connect the first inner wall 101c and the second inner wall 101d. The outlet of the air intake passage 101a and the protrusion 1012 are located between the two support portions 1013. The inlet of the air outlet passage 101b is located on the side wall of the support portion 1013 near the protrusion 1012.

[0071] The inlet of the air outlet 101b is arranged on the side wall of the support 1013 near the protrusion 1012, so that when the air flowing out of the annular protrusion 1016 flows to both sides of the annular protrusion 1016, it is easier to directly enter the inlet of the air outlet 101b.

[0072] The support part 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 part 1011.

[0073] The support portion 1013 may also have an electrode insertion hole 1013a inside, which can penetrate the air guide groove 1011b. The bracket 101 may also include a battery receiving portion 1014, which is connected to the docking portion 1011. The battery receiving portion 1014 is located on the side of the air guide groove 1011b away from the docking groove 1011a. The battery receiving portion 1014 has a battery receiving slot for receiving a battery. The electrode insertion hole 1013a connects the docking groove 1011a and the battery receiving slot. The electrode insertion hole 1013a is used to place the electrode 2231 for connecting the atomizer 200 and the battery 104.

[0074] like Figure 4 As shown, the side of the support portion 1013 away from the protrusion 1012 and the inner wall of the air guide groove 1011b form a receiving cavity 1013b, and the portion of the air guide groove 1011b located between the two support portions 1013 communicates with the receiving cavity 1013b.

[0075] Two support sections 1013 divide the air guide groove 1011b into three parts, of which the part located outside the two support sections 1013 is the receiving cavity 1013b. The outlet of the air intake passage 101a is located between the two support sections 1013.

[0076] The receiving cavity 1013b can be used to receive the second absorbent 227, such as absorbent cotton. When liquid leaks through the air outlet 101b into the air guide groove 1011b, the second absorbent 227 in the receiving cavity 1013b can absorb the liquid and prevent excessive liquid from accumulating between the two support portions 1013.

[0077] In this example, one of the receiving chambers 1013b has a microphone hole 1011c on its sidewall. The outer sidewall of the air guide channel 1011b may have a microphone mounting groove 102a, and the microphone hole 1011c may connect the receiving chamber 1013b and the microphone mounting groove 102a. During inhalation, the air pressure at the microphone hole 1011c will change. The microphone 102 installed in the microphone mounting groove 102a can detect the change in air pressure, thereby controlling the operation of the atomizer 200.

[0078] like Figure 4As shown, the bottom of the docking groove 1011a has a protrusion 10111, and the outlet of the air outlet 101b is located at the end of the protrusion 10111.

[0079] By arranging the protruding post 10111, the outlet of the air outlet 101b is located at the end of the protruding post 10111. This allows the outlet of the air outlet 101b to be higher than the bottom of the docking groove 1011a, making it difficult for the aerosol matrix leaked into the docking groove 1011a to enter the air outlet 101b.

[0080] Figure 5 This is a schematic diagram of the structure of a bracket provided in an embodiment of this application, as shown below. Figure 5 As shown, the bracket may further include a sealing plate 1015, which may be located in the air guide groove 1011b and is in a sealing fit with the inner wall of the air guide groove 1011b. A gap may exist between the sealing plate 1015 and the support portion 1013, allowing the three parts of the air guide groove 1011b, divided by the two support portions 1013, to remain connected through this gap.

[0081] The end of the sealing plate 1015 and the protrusion 1012 can abut against each other to enhance the blocking effect of the protrusion 1012 on the liquid and increase the difficulty for the liquid to pass over the protrusion 1012.

[0082] Figure 6 This is a schematic diagram of the structure of a power supply component provided in an embodiment of this application, such as... Figure 6 As shown, the power supply component may include a battery 104 and, as shown, ... Figures 2-5 In any of the brackets 101 shown, the battery 104 is located at the bottom of the docking part 1011.

[0083] As an example, the power supply assembly 100 may also include a circuit board 103 and a microphone 102. The outer wall of the docking portion 1011 may have a microphone mounting groove 102a, with the circuit board 103 located on one side of the bracket 101 and the microphone 102 located in the microphone mounting groove 102a, the microphone 102 being connected to the circuit board 103.

[0084] like Figure 6 As shown, the power supply assembly 100 also includes a display panel 105, which is located on the side of the circuit board 103 away from the microphone 102, and is electrically connected to the circuit board 103.

[0085] The display panel 105 is arranged 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 nearly parallel manner, which saves space and makes the structure of the power supply components more compact.

[0086] Figure 7 This is a schematic diagram of the structure of a power supply component provided in an embodiment of this application, such as... Figure 7 As shown, the power supply assembly 100 may also include a first adsorption member 228, which is located in the docking groove 1011a, and the outlet of the air outlet 101b is higher than the surface of the first adsorption member 228 away from the bottom of the docking groove 1011a.

[0087] The first adsorbent 228 arranged in the docking groove 1011a can adsorb the aerosol matrix that leaks into the docking groove 1011a. The outlet of the exhaust duct 101b is set above the surface of the first adsorbent 228 away from the bottom of the docking groove 1011a, so that the aerosol matrix that leaks into the docking groove 1011a will be preferentially absorbed by the first adsorbent 228, increasing the difficulty of the aerosol matrix leaking into the exhaust duct 101b.

[0088] For example, the first absorbent element 228 can be absorbent cotton.

[0089] Figure 8 This is a schematic diagram of an aerosol generating device provided in an embodiment of this application. Figure 8 As shown, 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 can be... Figure 6 or Figure 7 The power supply component 100 shown.

[0090] The atomizer 200 includes a reservoir assembly 210 and an atomizing assembly 220. The reservoir assembly 210 is used to store the aerosol matrix. The atomizing assembly 220 may include two atomizing coils 221.

[0091] The liquid storage assembly 210 may include a liquid reservoir housing 211, the interior of which forms a liquid reservoir for containing an aerosol matrix. The liquid storage assembly 210 may also include a base 212, which may be fixedly connected to or detachably connected to the liquid reservoir housing 211.

[0092] Figure 9 This is a schematic diagram of the internal structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 9 As shown, an atomizing chamber 200a is formed in the base 212, and an atomizing component 220 can be located in the atomizing chamber 200a. The atomizing component 220 is used to heat the aerosol matrix to form an aerosol.

[0093] In some examples, the liquid storage assembly 210 may also include a liquid storage element, such as a liquid storage cotton that has been adsorbed / wetted with an aerosol matrix.

[0094] The base 212 also has an exhaust channel 212a, one end of which is connected to the atomizing chamber 200a, and the other end is used to connect to the mouthpiece 3011.

[0095] The base 212 also has a liquid inlet channel 212b, which connects the atomizing chamber 200a and the liquid tank. The aerosol matrix can flow through the liquid inlet channel 212b to the atomizing core 221, keeping the atomizing core 221 moist. When the atomizing core 221 is working, it heats the aerosol matrix, releasing aerosol. During suction, the aerosol enters the nozzle 3011 through the exhaust channel 212a.

[0096] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Because the power supply assembly 100 is detachably connected to the atomizer 200, it is easy to replace the atomizer 200.

[0097] In other examples, the power supply assembly 100 and the atomizer 200 may be fixedly connected. For example, the housing portion of the power supply assembly 100 and the liquid tank housing 211 of the atomizer 200 are integrally formed.

[0098] For example, the power supply assembly 100 may include a housing 106, in which a bracket 101 is located. The housing 106 may engage with the liquid reservoir housing 211.

[0099] like Figure 9 As shown, a light-transmitting plate 1061 can also be installed on the outside of the housing 106. The light-transmitting plate 1061 can be arranged opposite to the display panel 105 so that the image displayed on the display panel 105 can be seen normally from outside the housing 106.

[0100] Keycaps 1062 can also be installed on the outside of the outer casing 106. The keycaps 1062 can be connected to the buttons on the surface of the circuit board 103 for user convenience.

[0101] The base 212 is located in the docking groove 1011a. A first adsorption element 228 is arranged between the base 212 and the bottom of the docking groove 1011a. The first adsorption element 228 is used to absorb the aerosol matrix that may leak to the bottom of the docking groove 1011a.

[0102] A third absorbent element 226 may also be provided in the base 212, which may be located between the base 212 and the bottom of the docking groove 1011a. The third absorbent element 226 may also be absorbent cotton.

[0103] like Figure 9As shown, the atomizing core includes a liquid guiding element 222 and a heating element 223, with the heating element 223 located on the side of the liquid guiding element 222 away from the liquid inlet channel 212b. The aerosol generating device also includes an electrode 2231, which is inserted into the bottom of the docking groove 1011a. One end of the electrode 2231 is located in the atomizing chamber 200a and abuts against the heating element 223. The other end of the electrode 2231 is used to connect to the battery 104.

[0104] The liquid guide 222 absorbs the aerosol matrix flowing out from the liquid inlet channel 212b and temporarily stores it, keeping the liquid guide 222 in a moist state. The heating element 223 heats the liquid guide 222, atomizing the aerosol matrix in the liquid guide 222 to form an aerosol. By arranging the heating element 223 on the side of the liquid guide 222 away from the liquid inlet channel 212b, and with the electrode 2231 abutting against the side of the heating element 223 away from the liquid guide 222, the atomizing core can be reinforced, ensuring stable installation of the atomizing core and preventing the aerosol matrix in the liquid inlet channel 212b from directly leaking into the atomizing chamber 200a.

[0105] Reference Figure 9 As shown, the atomizer 200 of the aerosol generating device may also include a seal 229, which is located on the side of the base 212 away from the docking part 1011. The seal 229 forms a seal with the inner wall of the liquid tank housing 211 to improve the sealing performance of the liquid tank.

[0106] Figure 9 The structure of the atomizer 200 in the aerosol generating device shown is only an example. In other possible implementations, the structure of the atomizer 200 in the aerosol generating device may also differ from that shown.
