[0004] Some aerosol generating devices have two air outlet channels, both connecting to atomizers. The airflow in each outlet channel can act on two atomizing coils respectively. Currently, it has been found that during operation, aerosol generating devices often have poor atomization effects, and even produce a burnt taste, resulting in a poor user experience. Utility Model Content

[0005] This application provides a support bracket for a power supply component, a power supply component, and an aerosol generating device, which can improve the atomization effect, avoid a burnt taste, and improve the user experience. 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 including a docking portion, the docking portion having a docking groove, an air guide groove, an air inlet duct and two air outlet ducts;

[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 first inner wall is connected with a guide ridge, which is opposite to the outlet of the air intake passage and is used to guide the airflow flowing out of the outlet of the air intake passage to both sides of the guide ridge.

[0010] The air outlet passage connects the air guide groove and the docking groove, and the inlets of the two air outlet passages are located on both sides of the guide ridge.

[0011] In some examples, the width of the guide ridge gradually decreases along the direction in which it protrudes relative to the first inner wall.

[0012] In some examples, the sidewall of the guide ridge near the inlet of the air outlet is concave.

[0013] In some examples, the guide ridge is tangent to the first inner wall near the inlet of the air outlet.

[0014] In some examples, the guide ridge is located near the sidewall of the inlet of one air outlet duct, symmetrical to the sidewall of the inlet of the other air outlet duct, and the plane of symmetry passes through the geometric center of the outlet of the air inlet duct.

[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 two support parts are located on both sides of the guide protrusion;

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

[0017] In some examples, a baffle plate is connected to the side wall of the support near the guide ridge, and the baffle plate is located on the side of the inlet of the air outlet near the second inner wall.

[0018] In some examples, the side of the baffle closest to the first inner wall and the side wall of the support form a liquid storage tank.

[0019] In some examples, the baffle plate satisfies at least one of the following:

[0020] The liquid baffle is inclined toward the direction of the first inner wall;

[0021] The baffle plate has a retaining edge on the side near the first inner wall, and the retaining edge is spaced apart from the side wall of the support portion.

[0022] In some examples, the side of the support portion away from the guide 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 communicates with the receiving cavity.

[0023] Secondly, embodiments of this application also provide a power supply component, which includes a battery and a bracket as described in the first aspect.

[0024] 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.

[0025] The beneficial effects of the technical solutions provided in this application include at least the following:

[0026] A docking slot and an air guide slot are provided at the docking part of the bracket. The docking slot is used to connect the atomizer, and the air guide slot is located at the bottom of the docking slot. The two are connected by two air outlet channels, and the air guide slot is also connected to the outside through an air inlet channel, allowing outside air to enter the air guide slot through the air inlet channel, and then enter the docking slot through the two air outlet channels. The first inner wall of the air guide slot is connected with a guide ridge, and the outlet of the air inlet channel is located on the second inner wall of the air guide slot. The outlet of the air inlet channel and the guide ridge are opposite each other, and the guide ridge can guide the airflow from the air inlet channel to both sides of the guide ridge. The inlets of the two air outlet channels are located on both sides of the guide ridge, so that the airflow guided to both sides of the guide ridge can enter the two air outlet channels respectively. Guided by the airflow ridges, the airflow can enter the two air outlet channels relatively stably, making the airflow in the air outlet channels stable and with small fluctuations. This avoids the situation where the airflow in one air outlet channel is too large and the airflow in the other air outlet channel is too small, thus stabilizing the atomization effect and preventing the atomizing core from burning and producing a burnt smell due to insufficient airflow.

[0048] 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 two atomizing cores 221.

[0049] The aerosol generating device has an inlet airway 101a and two outlet airways 101b, each connected to the inlet airway 101a. The outlet of each 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. The two outlet airways 101b are arranged in a one-to-one correspondence with the two atomizing cores 221.

[0050] The design values ​​or ranges of airflow rates in the two outlet channels 101b may be the same or different, depending on the design requirements of the aerosol generating device. During the suction process, if the deviation of the airflow rate in the outlet channel 101b from the design value is small, or if it falls within the design range, the corresponding atomizing core 221 can produce a good atomization effect. Excessive or insufficient airflow rate in the outlet channel 101b can affect the atomization effect. Especially when the airflow rate is too low, the atomizing core 221 may burn, resulting in a burnt aerosol. Therefore, it is generally desirable for the airflow rate in the outlet channel 101b to be stable within a suitable range.

[0051] The airflow in the two outlet channels 101b originates from the same inlet channel 101a, and the sum of the airflow rates in the two outlet channels 101b equals the airflow rate in the inlet channel 101a. However, in actual use, the airflow rate in the outlet channels 101b is often unstable. For example, the airflow rate in one outlet channel 101b may be too low, while the airflow rate in the other outlet channel 101b may be too high. This results in poor atomization and may even produce a burnt taste, severely impacting the user experience.

[0052] 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, an air guide groove 1011b, and an air intake passage 101a. The docking groove 1011a is used to connect with the atomizer 200. 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.

[0053] 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 outlet of the air intake passage 101a is located on the second inner wall 101d. A guide rib 1012 is connected to the first inner wall 101c, and the guide rib 1012 is opposite to the outlet of the air intake passage 101a.

[0054] Figure 4 This is a cross-sectional view of the mating portion of a bracket provided in an embodiment of this application, such as... Figure 4As shown, the exhaust duct 101b connects the air guide groove 1011b and the docking groove 1011a. The docking part 1011 has two exhaust ducts 101b, and the inlets of the two exhaust ducts 101b are located on both sides of the guide ridge 1012. The guide ridge 1012 is used to guide the airflow from the outlet of the intake duct 101a to both sides of the guide ridge 1012. Figure 4 The diagram schematically illustrates the direction of some airflow.

[0055] A docking groove 1011a and an air guide groove 1011b are provided in the docking part 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 two air outlet channels 101b. The air guide groove 1011b is also connected to the outside through the air inlet channel 101a, so that outside air can enter the air guide groove 1011b through the air inlet channel 101a, and then enter the docking groove 1011a from the air guide groove 1011b through the two air outlet channels 101b. By providing a guide ridge 1012 on the first inner wall 101c of the air guide groove 1011b, the outlet of the intake air passage 101a is located on the second inner wall 101d of the air guide groove 1011b. The outlet of the intake air passage 101a and the guide ridge 1012 are opposite to each other, and the guide ridge 1012 can guide the airflow from the intake air passage to both sides of the guide ridge. The inlets of the two outlet air passages 101b are located on both sides of the guide ridge 1012, so that the airflow guided to both sides of the guide ridge 1012 can enter the two outlet air passages 101b respectively. Under the guidance of the guide ridge 1012, the airflow can enter the two air outlet channels 101b relatively stably, so that the air flow in the air outlet channel 101b is stable and fluctuates little. This avoids the situation where the air flow in one air outlet channel 101b is too large and the air flow in the other air outlet channel 101b is too small, thus stabilizing the atomization effect and preventing the atomizing core 221 from burning and producing a burnt smell due to insufficient air flow.

[0056] Figure 5 This is a partially enlarged cross-sectional view of the docking portion of a bracket provided in an embodiment of this application, as shown below. Figure 5 As shown, along the direction in which the guide ridge 1012 protrudes relative to the first inner wall 101c, the width of the guide ridge 1012 gradually decreases.

[0057] The direction in which the guide ridge 1012 protrudes relative to the first inner wall 101c is the direction from the first inner wall 101c to the second inner wall 101d. The width of the guide ridge 1012 gradually decreases, causing the side wall 1012a of the guide ridge 1012 to be inclined relative to the first inner wall 101c. The inclination direction allows the airflow from the intake passage 101a to rush towards the guide ridge 1012 to gradually change direction along the side wall 1012a of the guide ridge 1012 and flow towards the inlet of the exhaust passage 101b.

[0058] In some examples, the cross-section of the guide ridge 1012 can be triangular, that is, the two sidewalls 1012a of the guide ridge 1012 can intersect.

[0059] In other possible implementations, the cross-section of the flow guide ridge 1012 can be quadrilateral, such as trapezoid, that is, the two sidewalls 1012a of the flow guide ridge 1012 do not intersect.

[0060] In some examples, the sidewall 1012a of the guide ridge 1012 near the inlet of the air outlet duct 101b is concave.

[0061] In this example, the sidewall 1012a of the guide ridge 1012 near the inlet of the air outlet duct 101b is concave, making the cross-section of the guide ridge 1012 a curved triangle with two concave curves on its two sides. Setting the sidewall 1012a of the guide ridge 1012 as a concave surface is more conducive to guiding the airflow to change its direction, making the airflow more stable.

[0062] In other examples, the cross-section of the guide ridge 1012 can also be a curved trapezoid with two concave curves on its sides.

[0063] In some possible implementations, the sidewall 1012a of the guide ridge 1012 near the inlet of the outlet air passage 101b can also be flat to facilitate machining.

[0064] In some examples, the sidewall 1012a of the guide ridge 1012 near the inlet of the air outlet duct 101b is tangent to the first inner wall 101c. For example, the sidewall 1012a and the first inner wall 101c are connected by a rounded corner. Another example is that the sidewall 1012a is a curved surface, which is tangent to the first inner wall 101c at its connection point.

[0065] The airflow exiting the intake duct 101a acts on the sidewall 1012a of the guide ridge 1012, flowing along the sidewall 1012a and gradually changing direction. The sidewall 1012a of the guide ridge 1012 is tangent to the first inner wall 101c, allowing the airflow to transition more smoothly to flow along the first inner wall 101c when it reaches the connection between the sidewall 1012a and the first inner wall 101c, making the airflow on both sides of the guide ridge 1012 in the air guide groove 1011b more stable.

[0066] As an example, the guide ridge 1012 is symmetrical to the sidewall 1012a of the inlet of one air outlet duct 101b and the sidewall 1012a of the inlet of the other air outlet duct 101b, and the plane of symmetry m passes through the geometric center of the outlet of the air inlet duct 101a.

[0067] That is, the guide ridge 1012 is a surface-symmetrical structure, and the geometric center of the outlet of the intake duct 101a is located on the symmetry plane m of the guide ridge 1012. When the airflow from the outlet of the intake duct 101a acts on the guide ridge 1012, half of the airflow can flow along one side wall 1012a of the guide ridge 1012 to the inlet of one outlet duct 101b, and the other half of the airflow can flow along the other side wall 1012a of the guide ridge 1012 to the inlet of the other outlet duct 101b, so that the airflow in the two outlet ducts 101b is roughly equal.

[0068] The outlet shape of the intake duct 101a can be a surface-symmetrical shape, and the symmetry plane of the outlet of the intake duct 101a can coincide with the symmetry plane m of the guide ridge 1012. For example, the outlet of the intake duct 101a can be rectangular, circular, or oval.

[0069] In other possible implementations, the geometric center of the outlet of the intake duct 101a can also be located on one side of the symmetry plane m of the guide ridge 1012, so that when the airflow from the outlet of the intake duct 101a acts on the guide ridge 1012, the airflow rates on both sides of the guide ridge 1012 are unequal. By adjusting the distance between the geometric center of the outlet of the intake duct 101a and the symmetry plane m of the guide ridge 1012, the ratio of airflow rates in the two outlet ducts 101b can be adjusted to meet specific design requirements. For example, the airflow rates in the two outlet ducts 101b can be set to a 1:2 ratio.

[0070] like Figure 5 As shown, the air guide groove 1011b also has two support parts 1013. The support parts 1013 are connected to the first inner wall 101c and the second inner wall 101d. The two support parts 1013 are located on both sides of the guide protrusion 1012.

[0071] The inlet of the air outlet duct 101b is located on the side wall of the support 1013 near the guide ridge 1012.

[0072] After being guided by the guide ridge 1012, the airflow exiting the intake duct 101a flows in a direction that is roughly parallel to the first inner wall 101c. By arranging support portions 1013 on both sides of the guide ridge 1012, the inlet of the exhaust duct 101b is located on the side wall of the support portion 1013 near the guide ridge 1012, making it easier for the airflow parallel to the first inner wall 101c to directly enter the inlet of the exhaust duct 101b.

[0073] The support part 1013 is arranged inside the air guide groove 1011b and connects the first inner wall 101c and the second inner wall 101d of the air guide groove 1011b, which can improve the structural strength of the docking part 1011.

[0074] 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.

[0075] like Figure 5 As shown, the side of the support portion 1013 away from the guide protrusion 1012 and the inner wall of the air guide groove 1011b form a receiving cavity 1013b, and the part of the air guide groove 1011b located between the two support portions 1013 communicates with the receiving cavity 1013b.

[0076] 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.

[0077] The outlet of the exhaust duct 101b is located in the docking groove 1011a. During the operation of the aerosol generating device, the generated condensate or leaked aerosol matrix may flow back from the exhaust duct 101b into the guide groove 1011b. The liquid flowing back into the guide groove 1011b may enter the intake duct 101a, causing blockage of the intake duct 101a, or even leaking along the intake duct 101a to the outside of the aerosol generating device. The receiving cavity 1013b can be used to receive the first absorbent 227, such as absorbent cotton. When liquid leaks from the exhaust duct 101b into the guide groove 1011b, the first absorbent 227 in the receiving cavity 1013b can absorb the liquid, preventing excessive liquid accumulation between the two support portions 1013.

[0078] 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.

[0079] Figure 6 This is a schematic diagram of the structure of a bracket provided in an embodiment of this application, as shown below. Figure 6 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.

[0080] like Figure 5 As shown, a baffle plate 10131 is connected to the side wall of the support part 1013 near the guide protrusion 1012. The baffle plate 10131 is located on the side of the inlet of the air outlet duct 101b near the second inner wall 101d.

[0081] By providing a baffle plate 10131 in the support part 1013, liquid flowing out from the inlet of the air outlet duct 101b can be blocked, so that the liquid adheres to the surface of the baffle plate 10131 and prevents the liquid from dripping onto the second inner wall 101d and entering the air inlet duct 101a.

[0082] In some examples, the side of the baffle plate 10131 near the first inner wall 101c and the side wall of the support portion 1013 form a liquid storage tank 10132.

[0083] The baffle plate 10131 protrudes from the side wall of the support portion 1013, and the surface of the baffle plate 10131 has relatively limited space for liquid adhesion. When there is a large amount of liquid, some of the liquid cannot adhere to the surface of the baffle plate 10131 and will drip over the baffle plate 10131 onto the second inner wall 101d. By using the baffle plate 10131 and the support portion 1013 to form a liquid storage tank 10132, a larger holding space can be created to hold more liquid, thereby further reducing the risk of liquid dripping onto the second inner wall 101d and entering the air intake passage 101a.

[0084] As an example, such as Figure 5 As shown, the baffle plate 10131 has a retaining edge 10133 on the side near the first inner wall 101c, and the retaining edge 10133 is spaced apart from the side wall of the support portion 1013.

[0085] The surface of the baffle 10133 near the support 1013, the surface of the baffle 10131 located between the baffle 10133 and the support 1013, and the surface of the support 1013 near the baffle 10133 form a liquid storage tank 10132, and the baffle 10133 prevents liquid from passing over the baffle 10131.

[0086] In some examples, the minimum distance between the retaining edge 10133 and the first inner wall 101c can be greater than the maximum distance between the inlet of the air outlet duct 101b and the first inner wall 101c. The minimum distance between the retaining edge 10133 and the first inner wall 101c refers to the distance from the edge of the retaining edge 10133 on the side closer to the first inner wall 101c to the first inner wall 101c; the maximum distance between the inlet of the air outlet duct 101b and the first inner wall 101c refers to the distance between the edge of the inlet of the air outlet duct 101b on the side farther from the first inner wall 101c and the first inner wall 101c.

[0087] The height of the baffle 10133 can affect the amount of liquid that the liquid storage tank 10132 can hold; the higher the baffle 10133, the larger the capacity of the liquid storage tank 10132. However, if the baffle 10133 is too high, it will obstruct airflow, which is not conducive to airflow entering the exhaust duct 101b. By making the minimum distance between the baffle 10133 and the first inner wall 101c greater than the maximum distance between the inlet of the exhaust duct 101b and the first inner wall 101c, the airflow facing the inlet of the exhaust duct 101b can enter the exhaust duct 101b without being obstructed by the baffle 10133.

[0088] Figure 7 This is a partially enlarged cross-sectional view of the docking portion of a bracket provided in an embodiment of this application, as shown below. Figure 7As shown, the baffle plate 10131 can be tilted towards the first inner wall 101c, such that the distance from the edge of the baffle plate 10131 near the first inner wall 101c to the first inner wall 101c is less than the distance from the edge of the baffle plate 10131 connected to the support portion 1013 to the first inner wall 101c. A V-shaped liquid storage groove 10132 is formed between the baffle plate 10131 and the support portion 1013 to accommodate the liquid flowing out from the air outlet 101b.

[0089] In other possible implementations, the baffle plate 10131 may have a retaining edge 10133 or be inclined toward the first inner wall 101c to further increase the volume of the liquid storage tank 10132.

[0090] Figure 8 This is a schematic diagram of the structure of a power supply component provided in an embodiment of this application, such as... Figure 8 As shown, the power supply assembly 100 includes a circuit board 103, a microphone 102, and a power supply unit 100. Figures 2-7 Any of the brackets 101 shown. The outer wall of the docking part 1011 may 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.

[0091] like Figure 8 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.

[0092] 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.

[0093] like Figure 8 As shown, the power supply assembly also includes a battery 104, which is located at the bottom of the docking portion 1011.

[0094] Figure 9 This is a schematic diagram of an aerosol generating device provided in an embodiment of this application. Figure 9 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 8 The power supply component 100 shown.

[0095] The atomizer 200 includes a liquid reservoir 210 and an atomizing assembly 220. The liquid reservoir 210 is used to store the aerosol matrix. The atomizing assembly 220 may include two atomizing coils 221.

[0096] 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.

[0097] Figure 10 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 10 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] like Figure 10 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.

[0105] 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.

[0106] The base 212 is located in the docking groove 1011a. A second adsorption element 228 is arranged between the base 212 and the bottom of the docking groove 1011a. The second adsorption element 228 is used to absorb the aerosol matrix that may leak to the bottom of the docking groove 1011a.

[0107] For example, the second absorbent 228 can be absorbent cotton.

[0108] 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.

[0109] like Figure 10 As 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.

[0110] 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.

[0111] Reference Figure 10 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.

[0112] Figure 10 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.
