[0050] Figure 1 is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application, as Figure 1As shown, the aerosol generating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 is configured to supply power to the atomizer 200.

[0051] Figure 2 is a schematic internal structure diagram of an aerosol generating device provided by an embodiment of the present application. As Figure 2 shown, 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.

[0052] The liquid storage assembly 210 may include a liquid chamber housing 211. A liquid chamber is formed inside the liquid chamber 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 or detachably connected to the liquid chamber housing 211. An atomization chamber 200a is formed in the base 212, and the atomization assembly 220 may be located in the atomization chamber 200a. The atomization assembly 220 is used to heat the aerosol matrix to form an aerosol.

[0053] In some examples, the liquid storage assembly 210 may further include a liquid storage member. For example, the liquid storage member may be a liquid storage cotton, and the liquid storage cotton is adsorbed / infiltrated with the aerosol matrix.

[0054] The base 212 further has an exhaust passage 212a. One end of the exhaust passage 212a communicates with the atomization chamber 200a, and the other end is used to communicate with the mouthpiece 3011.

[0055] The base 212 further has a liquid inlet passage 212b. The liquid inlet passage 212b communicates the atomization chamber 200a and the liquid chamber. The aerosol matrix can flow to the atomization assembly 220 through the liquid inlet passage 212b, so that the atomization assembly 220 is in a wet state. When the atomization assembly 220 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.

[0056] As Figure 2 shown, the power supply assembly 100 may include a bracket 101 and a battery 104. The bracket 101 is connected to the atomizer 200, and the battery 104 is used to supply power to the atomizer 200.

[0057] Figure 3 is a schematic structural diagram of a bracket provided by an embodiment of the present application. For the convenience of showing the structure of the bracket 101, Figure 3 at least a part of the bracket 101 is removed. As Figure 3 shown, the bracket 101 has a docking groove 1011a, a gas guiding groove 1011f, a first air passage 101a and a second air passage 101b. The docking groove 1011a is used to dock with the atomizer 200. The first air passage 101a communicates the docking groove 1011a and the gas guiding groove 1011f. The second air passage 101b communicates the gas guiding groove 1011f with the outside.

[0058] During the suction process, external air enters the air guide groove 1011f through the second air passage 101b, then enters the atomization chamber 200a through the first air passage 101a, and finally enters the mouthpiece 3011 through the exhaust passage 212a. In the air guide groove 1011f, the air flow enters the first air passage 101a in an asymmetric form.

[0059] Figure 4 It is a schematic diagram of the air flow simulation of an aerosol generating device provided by an embodiment of the present application. As Figure 4 shown, the air flow in the air guide groove 1011f enters the first air passage 101a in an asymmetric manner, causing the air flow in the first air passage 101a to deviate towards one side of the first air passage 101a, for example Figure 4 the left side shown. The air flow in the first air passage 101a deviates from the center of the first air passage 101a, resulting in an offset in the action of the air flow on the atomization component 220 in the atomization chamber 200a, causing differences in the atomization effects of different regions of the atomization component 220. The subsequent air flow entering the mouthpiece 3011 also deviates towards one side of the mouthpiece 3011, for example Figure 4 the air flow in the mouthpiece 3011 in [reference] deviates to the left, which causes the aerosol to easily condense on the inner wall of the mouthpiece 3011.

[0060] Figure 5 It is a schematic diagram of the air flow simulation of an aerosol generating device provided by an embodiment of the present application. As Figure 5 shown, when the air flow in the first air passage 101a flushes against the atomization component 220, there is also an offset in the X direction, which also causes differences in the atomization effects of different regions of the atomization component 220 and will also affect the overall atomization effect of the aerosol generating device.

[0061] Figure 6 It is a schematic diagram of the structure of a bracket of a power supply component provided by an embodiment of the present application. As Figure 6 shown, the bracket 101 includes a docking portion 1011. Figure 7 It is a schematic diagram of a partial structure of a bracket provided by an embodiment of the present application. To facilitate the display of the structure of the bracket 101, Figure 7 at least a part of the bracket 101 is removed in [reference], and the flow direction of part of the air flow in the bracket 101 during the suction process is schematically shown by black arrows. As Figure 7 shown, the docking portion 1011 has a docking groove 1011a, an air guide groove 1011f, a first air passage 101a, and a second air passage 101b.

[0062] The air guide groove 1011f is located outside the docking groove 1011a and at the bottom of the docking groove 1011a, that is, the air guide groove 1011f is located on the side of the bottom of the docking groove 1011a away from the opening of the docking groove 1011a.

[0063] The first air passage 101a communicates with the docking groove 1011a and the air guide groove 1011f. The inlet of the first air passage 101a communicates with the air guide groove 1011f, and the outlet communicates with the docking groove 1011a. The outlet of the second air passage 101b communicates with the air guide groove 1011f.

[0064] There is a first cylinder 10111 in the air guide groove 1011f. The first cylinder 10111 is located between the first air passage 101a and the second air passage 101b, and both ends of the first cylinder 10111 are connected to the inner wall of the air guide groove 1011f.

[0065] In this example, the first cylinder 10111 is located in the air guide groove 1011f, and the inlet of the first air passage 101a and the outlet of the second air passage 101b are located on the inner wall of the air guide groove 1011f. The first cylinder 10111 being located between the first air passage 101a and the second air passage 101b means that the first cylinder 10111 is located between the inlet of the first air passage 101a and the outlet of the second air passage 101b.

[0066] Exemplarily, the inlet of the first air passage 101a and the outlet of the second air passage 101b can be one of a rectangle, a rounded rectangle, a circle, an ellipse, and a kidney shape.

[0067] Figure 8 It is a schematic diagram of a partial structure of a stent provided by an embodiment of the present application. To facilitate the display of the structure of the stent 101, Figure 8 at least a part of the stent 101 is removed, and the flow direction of part of the air flow in the stent 101 during the suction process is schematically shown by a black arrow. Combining Figure 7 and Figure 8 As shown, there are gaps between both sides of the first cylinder 10111 and the inner wall of the air guide groove 1011f, enabling the gas in the second air passage 101b to bypass the first cylinder 10111 from both sides of the first cylinder 10111 and enter the first air passage 101a.

[0068] By providing a docking groove 1011a and an air guide groove 1011f at the docking portion 1011 of the bracket 101, the docking groove 1011a is used to connect the atomizer 200. The air guide groove 1011f is located at the bottom of the docking groove 1011a, and the two are connected through the first air passage 101a. The air guide groove 1011f is also connected to the outside through the second air passage 101b, so that the outside air can enter the air guide groove 1011f through the second air passage 101b, and then enter the docking groove 1011a from the air guide groove 1011f through the first air passage 101a. The first cylinder 10111 in the air guide groove 1011f is located between the first air passage 101a and the second air passage 101b. Since there are gaps between both sides of the first cylinder 10111 and the inner wall of the air guide groove 1011f, the gas in the second air passage 101b can bypass the first cylinder 10111 from both sides of the first cylinder 10111 and enter the first air passage 101a. Therefore, the air can enter the first air passage 101a more symmetrically, avoiding the airflow from shifting to one side in the first air passage 101a, so that the flow velocity distribution in the first air passage 101a is more uniform, which is beneficial to improving the atomization effect of the atomizer 200 and avoiding the condensation phenomenon in the nozzle 3011.

[0069] To facilitate the processing of the structure in the air guide groove 1011f and the assembly of other possible structures in the air guide groove 1011f, the bracket 101 can be a split structure. For example Figure 6 As shown, the bracket 101 may further include a sealing plate 1012, and the sealing plate 1012 is connected to the docking portion 1011 to form two opposite side walls of the air guide groove 1011f. Exemplarily, the sealing plate 1012 can be made of polycarbonate plastic.

[0070] Figure 9 is a schematic structural diagram of a bracket provided by an embodiment of the present application, Figure 7 and Figure 9 are different perspectives of the same bracket 101. As shown in Figure 7 and Figure 9 The air guide groove 1011f has a first inner wall 101c and a second inner wall 101d. Among them, the first inner wall 101c is the inner wall of the air guide groove 1011f close to the docking groove 1011a, and the second inner wall 101d is opposite to the first inner wall 101c. The inlet of the first air passage 101a is located on the first inner wall 101c. One end of the first cylinder 10111 is connected to the first inner wall 101c, and the other end of the first cylinder 10111 is connected to the second inner wall 101d.

[0071] In this example, the first cylinder 10111 is arranged along the Y direction. One end of the first cylinder 10111 and the inlet of the first air passage 101a are located on the same inner wall of the air guide groove 1011f. After the air in the second air passage 101b enters the air guide groove 1011f, it can bypass the first cylinder 10111 from both sides of the first cylinder 10111 and then enter the first air passage 101a along the Y direction.

[0072] In some possible implementation manners, one end of the first cylinder 10111 and the inlet of the first air passage 101a may be located on different inner walls of the air guide groove 1011f. For example, Figure 10 is a schematic partial structure diagram of a stent provided by an embodiment of the present application. Figure 10 The flow directions of some airflows in the stent 101 are schematically shown by black arrows in, as Figure 10 shown, the first cylinder 10111 is arranged along the Z direction, and there are gaps between the first cylinder 10111 and the first inner wall 101c and the second inner wall 101d. The airflows can bypass the first cylinder 10111 from the side of the first cylinder 10111 close to the first inner wall 101c and the side of the first cylinder 10111 close to the second inner wall 101d.

[0073] For an example where the first cylinder 10111 is in contact with or connected to the second inner wall 101d, the airflows enter the first air passage 101a after passing through the gap between the first cylinder 10111 and the first inner wall 101c. During this process, the turning radius of the airflows is small and the direction changes greatly, so that the airflows in the first air passage 101a will deviate to one side.

[0074] In this example, there are gaps between the first cylinder 10111 and both the first inner wall 101c and the second inner wall 101d. A part of the airflows enter the first air passage 101a after passing through the gap between the first cylinder 10111 and the first inner wall 101c, and another part of the airflows enter the first air passage 101a after passing through the gap between the first cylinder 10111 and the second inner wall 101d. Since the distance from the gap between the first cylinder 10111 and the second inner wall 101d to the inlet of the first air passage 101a is relatively long, after the airflows bypass the first cylinder 10111, there is a long path to change the flow direction, so that when the airflows enter the first air passage 101a, the flow direction of the airflows is closer to the extending direction of the first air passage 101a, and the phenomenon that the airflows in the first air passage 101a deviate to one side is improved.

[0075] As an example, the first cylinder 10111 may be cylindrical. When the airflows in the air guide groove 1011f bypass the first cylinder 10111, the cylindrical first cylinder 10111 has a relatively small resistance to the airflows.

[0076] The first cylinder 10111 can be a structure in the bracket 101 for enhancing the structural strength. For example, both ends of the first cylinder 10111 are connected to the inner wall of the air guide groove 1011f, which can improve the structural strength of the docking part 1011 and prevent deformation of the air guide groove 1011f. According to the designs of different aerosol generating devices, the first cylinder 10111 can have different arrangements in the air guide groove 1011f.

[0077] The first cylinder 10111 can also be used for arranging other structures. For example Figure 7 As shown, the first cylinder 10111 can be a tubular structure, and the lumen of the first cylinder 10111 can be used for arranging structures that need to pass through the air guide groove 1011f. For example, the first cylinder 10111 can be used to accommodate the electrode 2231 that supplies power to the atomization assembly 220.

[0078] In this example, connecting one end of the first cylinder 10111 to the first inner wall 101c and the other end of the first cylinder 10111 to the second inner wall 101d can facilitate the arrangement of the electrode 2231 passing through the air guide groove 1011f.

[0079] As Figure 9 shown, there is also a second cylinder 10112 in the air guide groove 1011f. Both ends of the second cylinder 10112 are respectively connected to the inner wall of the air guide groove 1011f, and the first air passage 101a is located between the first cylinder 10111 and the second cylinder 10112.

[0080] By arranging the second cylinder 10112, not only can the structural strength of the bracket 101 be further enhanced, but it is also more convenient for arranging the electrode 2231. The second cylinder 10112 can also be a tubular structure. The atomization assembly 220 usually requires two electrodes 2231 for power supply. Arranging both electrodes 2231 in the first cylinder 10111 not only poses a risk of short circuit, but also increases the diameter of the first cylinder 10111, resulting in a relatively small gap between the first cylinder 10111 and the inner wall of the air guide groove 1011f, which is not conducive to the passage of air flow. By arranging the first cylinder 10111 and the second cylinder 10112, electrodes 2231 can be arranged in both the first cylinder 10111 and the second cylinder 10112 without setting the diameter of the first cylinder 10111 too large.

[0081] In some examples, the geometric center of the inlet of the first air passage 101a, the geometric center of the outlet of the second air passage 101b, and the axis of the first cylinder 10111 are coplanar.

[0082] Arranging the three in the same plane allows the air in the second air passage 101b to enter the air guiding groove 1011f and then more symmetrically bypass the first cylinder 10111 and enter the first air passage 101a more symmetrically, making the air flow in the first air passage 101a more centered.

[0083] The air guiding groove 1011f can be a symmetric structure, such as a face-symmetric structure. The geometric center of the inlet of the first air passage 101a, the geometric center of the outlet of the second air passage 101b, and the axis of the first cylinder 10111 can be located on the symmetric plane of the air guiding groove 1011f, which can further improve the symmetry of the air flow in the air guiding groove 1011f.

[0084] Figure 11 It is a schematic structural diagram of a bracket provided by an embodiment of the present application. As Figure 11 shown, the side wall of the air guiding groove 1011f can have a microphone hole 1011c, and the second cylinder 10112 is located between the microphone hole 1011c and the first air passage 101a. There are gaps on both sides of the second cylinder 10112 and the inner wall of the air guiding groove 1011f (which can be referred to Figure 7 and Figure 8 ), so that the gas in the microphone hole 1011c can bypass the second cylinder 10112 from both sides of the second cylinder 10112 and enter the first air passage 101a.

[0085] During the process of using the atomizer generating device, when the user sucks, it will cause a change in the air pressure in the air guiding groove 1011f. The microphone 102 in the atomizer generating device is aligned with the microphone hole 1011c and is used to detect the change in the air pressure at the microphone hole 1011c to control the operation of the atomizer generating device. During the suction process, a small amount of air at the microphone hole 1011c will also enter the first air passage 101a.

[0086] Since there are also gaps between the two sides of the second cylinder 10112 and the inner wall of the air guiding groove 1011f, the gas at the microphone hole 1011c can bypass the second cylinder 10112 from both sides of the second cylinder 10112 and enter the first air passage 101a. Therefore, the air can enter the first air passage 101a more symmetrically, further improving the flow velocity distribution of the air flow in the first air passage 101a.

[0087] As an example, the second cylinder 10112 can be cylindrical. When the air flow in the air guiding groove 1011f bypasses the second cylinder 10112, the cylindrical second cylinder 10112 has less resistance to the air flow.

[0088] In some examples, the geometric center of the inlet of the first air passage 101a, the geometric center of the microphone hole 1011c, and the axis of the second cylinder 10112 are coplanar.

[0089] Arranging the three in the same plane can make the air at the microphone hole 1011c bypass the second cylinder 10112 more symmetrically and enter the first air duct 101a more symmetrically, making the airflow in the first air duct 101a more centered.

[0090] As an example, the geometric center of the inlet of the first air duct 101a, the geometric center of the outlet of the second air duct 101b, the geometric center of the microphone hole 1011c, the axis of the first cylinder 10111, and the axis of the second cylinder 10112 can be in the same plane.

[0091] As Figure 11 shown, a baffle 10113 is connected to the inner wall of the air guide groove 1011f. A clamping groove 10113a is formed between the inner wall of the air guide groove 1011f close to the docking groove 1011a and the baffle 10113. The clamping groove 10113a is used to accommodate the first adsorbent 10114.

[0092] By cooperating the baffle 10113 with the first inner wall 101c of the docking groove 1011a to form the clamping groove 10113a for installing the first adsorbent 10114, the first adsorbent 10114 is used to adsorb the aerosol matrix leaked into the air guide groove 1011f, which can prevent the aerosol matrix from entering the microphone hole 1011c or the second air duct 101b.

[0093] As Figure 11 shown, the bracket 101 may further include an air inlet pipe 1013. The air inlet pipe 1013 is connected to the docking part 1011, and the air inlet pipe 1013 can be communicated with the inlet of the second air duct 101b.

[0094] Figure 12 is a schematic structural diagram of a power supply component provided by an embodiment of the present application. As Figure 12 shown, the power supply component 100 includes a circuit board 103, a microphone 102, and any one of the brackets 101 as Figures 6 to 11 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.

[0095] As Figure 12 shown, the power supply component 100 further includes a display panel 105. The display panel 105 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.

[0096] 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 saves space and can make the structure of the power supply component more compact.

[0097] AsFigure 12 As shown, the power supply assembly further includes a battery 104, and the battery 104 is located at the bottom of the docking portion 1011.

[0098] Figure 13 It is a schematic internal structure diagram of an aerosol generating device provided by an embodiment of the present application. As Figure 13 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.

[0099] 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.

[0100] In other examples, the power supply assembly 100 and the atomizer 200 may 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 an integral structure.

[0101] Exemplarily, the power supply assembly 100 may include a first outer shell 106, and the bracket 101 is located in the first outer shell 106. The first outer shell 106 can be snap-fitted with the liquid storage housing 211. The aerosol generating device may include a second outer shell 301 and an end cap 302. The end cap 302 is connected to the second outer shell 301 to form a receiving cavity, and both the power supply assembly 100 and the atomizer 200 are located in the receiving cavity. The second outer shell 301 may be connected with a mouthpiece 3011. For example, the second outer shell 301 and the mouthpiece 3011 may be an integral structure; or, the second outer shell 301 and the mouthpiece 3011 are detachably connected to facilitate the replacement of the mouthpiece 3011.

[0102] The base 212 is located in the docking groove 1011a. A second adsorbent 228 is arranged between the base 212 and the bottom of the docking groove 1011a, and the second adsorbent 228 is used to absorb the aerosol matrix that may leak between the base 212 and the bottom of the docking groove 1011a.

[0103] Exemplarily, the second adsorbent 228 may be absorbent cotton.

[0104] As Figure 13 shown, 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.

[0105] The base 212 further has a liquid inlet passage 212b, and the liquid inlet passage 212b communicates the atomization chamber 200a and the liquid storage chamber. The atomization assembly includes an atomization core, and the atomization core is located in the atomization chamber 200a.

[0106] The aerosol matrix can flow through the liquid inlet channel 212b to the atomization core, making the atomization core in a wet state. When the atomization core works, it heats the aerosol matrix and releases aerosol into the atomization chamber 200a. During the suction process, the aerosol in the atomization chamber 200a enters the mouthpiece 3011 through the exhaust channel 212a.

[0107] As Figure 13 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, and the electrode 2231 is inserted at the bottom of the docking groove 1011a. One end of the electrode 2231 is located in the atomization chamber 200a and abuts against the heating member 223. The other end of the electrode 2231 is used to connect to the battery 104.

[0108] Exemplarily, the aerosol generating device can include two electrodes 2231. One electrode 2231 is inserted in the first cylinder 10111, and the other electrode 2231 is inserted in the second cylinder 10112.

[0109] 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 aerosol. By arranging the heating member 223 on the side of the liquid guiding member 222 away from the liquid inlet channel 212b and making the electrode 2231 abut 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 chamber 200a.

[0110] Referring to Figure 13 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.

[0111] 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.

[0112] Figure 13 The structure of the atomizer 200 in the shown aerosol generating device 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.

[0113] Figure 14It is a schematic diagram of the air flow simulation of an aerosol generating device provided by an embodiment of the present application. As Figure 4 shown, the air flow in the air guiding groove 1011f enters the first air passage 101a in a symmetric manner, and the air flow in the first air passage 101a remains in the central position. In the atomization chamber 200a, the air flow acts on the middle position of the atomization assembly 220, so that the atomization effects of different regions of the atomization assembly 220 have little difference. Subsequently, the air flow entering the mouthpiece 3011 also remains in the center, and the aerosol is not easily condensed on the inner wall of the mouthpiece 3011.

[0114] Figure 15 It is a schematic diagram of the air flow simulation of an aerosol generating device provided by an embodiment of the present application. As Figure 15 shown, when the air flow in the first air passage 101a flushes the atomization assembly 220, it is also in the central state in the X direction, and the air flow distribution is relatively symmetric, so that the atomization effects of different regions of the atomization assembly 220 have little difference, which is beneficial to improving the overall atomization effect of the aerosol generating device.
