[0003] The power supply includes a bracket with a recess into which the atomizer is inserted. Currently, some aerosol generators have been found to leak aerosol matrix or condensate during use, affecting the user experience. Utility Model Content

[0004] This application provides a power supply support assembly, a power supply, and an aerosol generation device, which can reduce the risk of aerosol matrix leakage. The technical solution is as follows: In a first aspect, embodiments of this application provide a power supply bracket assembly, the bracket assembly including a bracket and a barrier member, the bracket including a docking portion, the docking portion having a groove, the barrier member being disposed in the groove, the barrier member and the docking portion forming a docking groove, the docking groove being located on the side of the barrier member away from the bottom surface of the groove; The side of the barrier away from the docking groove and the docking part form an air inlet cavity. The barrier is also provided with an airflow channel, which connects the docking groove and the air inlet cavity. The docking part is also provided with an air intake channel, which is connected to the air intake chamber, and the air intake channel and the airflow channel are staggered.

[0005] In some examples, the barrier has a guide surface opposite the air intake channel, the guide surface being a concave curved surface that extends into the airflow channel.

[0006] In some examples, the guide surface is provided with multiple guide grooves that extend from the guide surface to the airflow channel from a position opposite the air intake channel.

[0007] In some examples, the bottom surface of the groove is provided with a first enclosure plate, and the side of the barrier away from the docking groove is provided with a second enclosure plate, and the first enclosure plate and the second enclosure plate are nested together to form the air intake cavity.

[0008] In some examples, the barrier has a first boss on the side near the docking groove, and the airflow channel passes through the top surface of the first boss.

[0009] In some examples, the docking portion is further provided with an air guide groove, which is located outside the groove and at the bottom of the groove, and the air intake channel connects the air guide groove and the air intake chamber.

[0010] In some examples, the bottom of the groove is provided with a second boss, which is located in the air intake cavity, and the air intake channel passes through the top surface of the second boss.

[0011] In some examples, a fourth liquid suction element is provided in the air intake chamber.

[0012] Secondly, embodiments of this application also provide a power source, the power source including a battery and a support assembly as described in the first aspect, the battery being housed in the support assembly.

[0013] Thirdly, embodiments of this application also provide an aerosol generating device, the aerosol generating device including an atomizer and a power supply as described in the second aspect, the power supply being connected to the atomizer for supplying power to the atomizer.

[0014] In some examples, an atomizing cavity is formed between the atomizer and the barrier, the atomizer includes two atomizing cores located in the atomizing cavity, and the atomizer has an exhaust passage communicating with the atomizing cavity, the inlet of the exhaust passage being located between the two atomizing cores; The barrier is provided with two airflow channels, and the airflow channels are arranged in a one-to-one correspondence with the atomizing core.

[0015] In some examples, the distance from the geometric center of the projection of the outlet of the airflow channel onto the first surface to the first side is greater than the distance to the second side, the first surface being the surface of the atomizing core near the airflow channel, the first side being the side of the first surface near the inlet of the exhaust channel, and the second side being the side of the first surface away from the inlet of the exhaust channel.

[0016] The beneficial effects of the technical solutions provided in this application include at least the following: By installing a barrier in the groove of the bracket's docking part, a docking groove is formed by the barrier and the docking part, allowing the atomizer to be connected. An air inlet chamber is formed by the barrier and the docking part, located on the side of the barrier away from the docking groove. The barrier has an airflow channel connecting the air inlet chamber and the docking groove, and the docking part has an air inlet channel communicating with the air inlet chamber. This allows airflow to enter the air inlet chamber through the air inlet channel during aerosol generation, then through the airflow channel into the docking groove, and finally into the atomizer. Because the air inlet channel and the airflow channel are staggered, even if liquid leaks from the atomizer into the airflow channel, it will not drip directly into the air inlet channel. This prevents liquid from leaking outside the aerosol generator, significantly reducing the risk of leakage and improving the user experience. Attached Figure Description

[0026] 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 100 and an atomizer 200. The power supply 100 supplies power to the atomizer 200. The atomizer 200 includes an atomizing component 220 for heating the aerosol matrix to form an aerosol. The atomizing component 220 includes an atomizing core 221.

[0027] The power supply 100 is provided with an air inlet duct 101a and an air outlet duct 101b, and the air outlet duct 101b is connected to the air inlet duct 101a. The outlet of the air outlet duct 101b is opposite to the atomizing core 221, so that the airflow in the air outlet duct 101b can flow to the atomizing core 221.

[0028] Some aerosol generating devices pose a risk of leakage. For example, during product testing, such as high and low temperature cycling tests and negative pressure tests, and during daily use, the aerosol matrix stored in the atomizer 200 or the generated condensate may leak outside the aerosol generating device through various pathways due to pressure differences inside and outside the device or other environmental factors, thus affecting the user experience. For instance, the aerosol matrix or condensate at the atomizing component 220 may drip into the outlet air duct 101b, then flow to the inlet air duct 101a, and then leak outside the aerosol generating device via the inlet air duct 101a.

[0029] Figure 2 This is an exploded structural diagram of a power supply bracket assembly provided in an embodiment of this application, as shown below. Figure 2 As shown, the bracket assembly 10 includes a bracket 11 and a barrier 12. The bracket 11 includes a docking portion 111, and the docking portion 111 is provided with a groove 111a.

[0030] Figure 3 This is a schematic diagram of the internal structure of a power supply bracket assembly provided in an embodiment of this application. It is for illustrative purposes only. Figure 3 The structure of the support assembly 10 is omitted. For example... Figure 3 As shown, the barrier 12 is disposed in the groove 111a, and the barrier 12 and the docking part 111 form a docking groove 111c. The docking groove 111c is located on the side of the bottom surface of the barrier 12 away from the groove 111a.

[0031] The side of the barrier 12 away from the docking groove 111c and the docking part 111 form an air inlet chamber 111d. The barrier 12 is also provided with an airflow channel 12c, which connects the docking groove 111c and the air inlet chamber 111d.

[0032] The docking part 111 is also provided with an air intake channel 111f, which is connected to the air intake chamber 111d. The air intake channel 111f and the airflow channel 12c are staggered.

[0033] The misalignment of the intake channel 111f and the airflow channel 12c means that the airflow direction at the outlet of the intake channel 111f is not collinear with the airflow direction at the inlet of the airflow channel 12c.

[0034] The outlet of the intake passage 111f is located at the end where the intake passage 111f connects to the intake chamber 111d, and the inlet of the airflow passage 12c is located at the end where the airflow passage 12c connects to the intake chamber 111d.

[0035] By providing a barrier 12 in the groove 111a of the docking portion 111 of the bracket 11, a docking groove 111c is formed by the barrier 12 and the docking portion 111, allowing the atomizer 200 to be connected through the docking groove 111c. An air inlet chamber 111d is formed by the barrier 12 and the docking portion 111, with the air inlet chamber 111d located on the side of the barrier 12 away from the docking groove 111c. The barrier 12 has an airflow channel 12c that connects the air inlet chamber 111d and the docking groove 111c, and the docking portion 111 has an air inlet channel 111f that connects to the air inlet chamber 111d. This allows airflow to enter the air inlet chamber 111d through the air inlet channel 111f during the use of the aerosol generating device, and then enter the docking groove 111c through the airflow channel 12c before entering the atomizer 200. Since the air intake channel 111f and the airflow channel 12c are staggered, even if the liquid leaked from the atomizer 200 enters the airflow channel 12c, it will not drip directly into the air intake channel 111f. This can prevent the liquid from leaking to the outside of the aerosol generating device, greatly reducing the risk of leakage from the aerosol generating device and improving the user experience.

[0036] like Figure 3 As shown, the barrier 12 and the docking portion 111 also form a liquid storage cavity 111b, which is located between the barrier 12 and the bottom surface of the groove 111a. That is, the barrier 12 divides the groove 111a into the liquid storage cavity 111b and the docking groove 111c for connecting the atomizer 200.

[0037] The barrier 12 has a liquid storage tank 12a recessed on the side of the bottom surface away from the groove 111a. The barrier 12 is provided with a first through hole 12b, which is located outside the liquid storage tank 12a and connects the liquid storage cavity 111b and the docking groove 111c.

[0038] Liquid leaking from the atomizer 200 can drip onto the barrier 12. By providing a recessed liquid storage tank 12a on the side of the barrier 12 away from the bottom surface of the groove 111a, the liquid leaking from the atomizer 200 can be stored in the liquid storage tank 12a, thereby preventing liquid from leaking outside the aerosol generating device. By providing a first through hole 12b on the barrier 12 connecting the liquid storage chamber 111b and the docking groove 111c, after the liquid storage tank 12a is filled with liquid, the overflowing liquid can flow along the surface of the barrier 12 through the first through hole 12b into the liquid storage chamber 111b for storage, preventing the aerosol matrix from leaking outside the aerosol generating device, thereby greatly reducing the risk of liquid leakage from the aerosol generating device and improving the user experience.

[0039] As an example, the liquid storage tank 12a can be located in the middle of the barrier member 12, and the first through hole 12b can be located near the edge of the barrier member 12, so that the liquid storage tank 12a and the first through hole 12b are far apart, allowing a larger amount of aerosol matrix to adhere between the liquid storage tank 12a and the first through hole 12b. One or more first through holes 12b can be provided; for example, two first through holes 12b can be provided, with the liquid storage tank 12a located between the two first through holes 12b.

[0040] Figure 4 This is a schematic diagram of the structure of a barrier provided in an embodiment of this application. Figure 1 ,like Figure 4 As shown, the barrier 12 has a liquid guiding groove 120 on the side of the bottom surface of the groove 111a away from the groove. The liquid guiding groove 120 is connected to at least one of the liquid storage tank 12a and the first through hole 12b.

[0041] The barrier 12 includes a plate body portion, and the liquid guiding groove 120 may be provided at least in the plate body portion.

[0042] The liquid guiding groove 120 restricts the flow direction of liquid adhering to the surface of the barrier 12, preventing the liquid from flowing everywhere. The liquid guiding groove 120 communicates with the storage tank 12a. Before the storage tank 12a is full, it facilitates the flow of liquid along the liquid guiding groove 120 into the storage tank 12a. After the storage tank 12a is full, the overflowing liquid can flow along the liquid guiding groove 120, adhering to a larger area on the surface of the barrier 12. The liquid guiding groove 120 is connected to the first through hole 12b, facilitating the flow of liquid adhering to the surface of the barrier 12 along the liquid guiding groove 120 through the first through hole 12b into the storage cavity 111b.

[0043] In addition, the liquid guiding groove 120 increases the surface area of ​​the barrier 12, allowing more liquid to adhere to the surface of the barrier 12.

[0044] Reference Figure 2 As shown, in some examples, the support assembly also includes a first suction element 131 located in the reservoir 111b.

[0045] For example, the first absorbent element 131 can be absorbent cotton, such as organic cotton, ceramic cotton, bamboo fiber cotton, or composite cotton.

[0046] A first liquid suction element 131 is provided in the liquid storage chamber 111b, which can absorb the liquid entering the liquid storage chamber 111b from the first through hole 12b, thereby binding the liquid and preventing it from flowing around, which helps to further reduce the risk of leakage.

[0047] As an example, the liquid guiding groove 120 includes a plurality of first grooves 1201 and a plurality of second grooves 1202. The first grooves 1201 extend on the surface of the barrier member 12 along a first direction X, and the second grooves 1202 extend on the surface of the barrier member 12 along a second direction Y, wherein the first direction X and the second direction Y intersect.

[0048] As an example, the first direction X and the second direction Y can be perpendicular to each other.

[0049] The aerosol generating device is usually cylindrical. The first direction X and the second direction Y can be perpendicular to the length direction of the aerosol generating device, which is the insertion direction of the atomizer 200 and the docking groove 111c.

[0050] At least a portion of the first groove 1201 and at least a portion of the second groove 1202 intersect each other. One end of at least a portion of the first groove 1201 extends to the liquid storage tank 12a, and at least a portion of the second groove 1202 communicates with the first through hole 12b.

[0051] The arrangement of the first groove 1201 can guide the liquid adhering to the barrier 12 to flow along the first direction X, and the arrangement of the second groove 1202 can guide the liquid adhering to the barrier 12 to flow along the second direction Y. The first groove 1201 extends to the liquid storage tank 12a, and can guide the liquid to flow into the liquid storage tank 12a along the first groove 1201, or guide the liquid to flow to the second groove 1202 when the liquid storage tank 12a overflows. The second groove 1202, which communicates with the first through hole 12b, can guide the liquid to flow to the first through hole 12b.

[0052] As an example, the liquid channel 120 may also include a third channel 1203, which may communicate with the first through hole 12b and with a plurality of second channels 1202, thereby facilitating the entry of liquid into the first through hole 12b.

[0053] like Figure 4 As shown, the barrier 12 has two upright plates 121 on the side of the bottom surface of the groove 111a away from the groove, and the two upright plates 121 are arranged facing each other. The liquid storage tank 12a is located between the two upright plates 121, and the first through hole 12b is located on the side of the upright plate 121 away from the liquid storage tank 12a. The upright plates 121 can be connected to the surface of the plate body.

[0054] When the power supply 100 is connected to the atomizer 200, the upright plate 121 is used to plug into the atomizer 200, making the connection between the power supply 100 and the atomizer 200 more secure. Liquid can also adhere to the surface of the upright plate 121, allowing more liquid to adhere to the surface of the barrier 12, which helps to further reduce the risk of leakage.

[0055] like Figure 4As shown, the surface of the upright plate 121 is provided with a plurality of fourth grooves 121b, at least some of the fourth grooves 121b connecting the side of the upright plate 121 near the liquid storage tank 12a and the side away from the liquid storage tank 12a.

[0056] The fourth groove 121b on the surface of the vertical plate 121 increases the surface area of ​​the vertical plate 121, allowing more liquid to adhere to its surface. The fourth groove 121b connecting the two sides of the vertical plate 121 allows the liquid adhering to the surface of the vertical plate 121 to flow through the fourth groove 121b to the side of the vertical plate 121 closer to the liquid storage tank 12a, or to the side closer to the first through hole 12b.

[0057] like Figure 4 As shown, a receiving groove 121a is provided on the surface of the upright plate 121 away from the liquid storage tank 12a. (Refer to...) Figure 2 The receiving tank 121a is provided with a second liquid suction element 132.

[0058] For example, the second absorbent element 132 can be absorbent cotton, such as organic cotton, ceramic cotton, bamboo fiber cotton, or composite cotton.

[0059] The second liquid suction element 132 can absorb some of the liquid flowing to the side of the vertical plate 121 away from the liquid storage tank 12a, so that more liquid can be stored in the support assembly 10, which helps to further reduce the risk of leakage of the aerosol generating device.

[0060] like Figure 2 As shown, the support assembly also includes a third liquid suction member 133, which is located in the docking groove 111c and on the side of the upright plate 121 away from the liquid storage tank 12a.

[0061] For example, the third absorbent element 133 can be absorbent cotton, such as organic cotton, ceramic cotton, bamboo fiber cotton, or composite cotton.

[0062] The third suction element 133 can absorb liquid flowing to the side of the vertical plate 121 away from the liquid storage tank 12a. By making full use of the space on the side of the vertical plate 121 away from the liquid storage tank 12a, the suction element can be arranged, allowing the support assembly 10 to store more liquid, which helps to further reduce the risk of leakage from the aerosol generation device.

[0063] When the power supply 100 is connected to the atomizer 200, the third liquid suction element 133 can be embedded in the atomizer 200 to absorb the liquid that leaks into the docking groove 111c.

[0064] The third liquid suction element 133 can cover the first through hole 12b, so that it does not affect the flow of liquid into the liquid storage chamber 111b through the first through hole 12b, and can also absorb the liquid that may flow back from the first through hole 12b to the docking tank 111c when the aerosol generating device is placed at an angle.

[0065] 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 bottom surface of the groove 111a is provided with a first surrounding plate 113. Figure 6 This is a schematic diagram of the structure of a barrier provided in an embodiment of this application. Figure 2 ,like Figure 6 As shown, a second enclosure plate 122 is provided on the side of the barrier member 12 away from the docking groove 111c. The second enclosure plate 122 can be connected to the side of the plate body away from the upright plate 121. (Refer to...) Figure 3 As shown, the first enclosure 113 and the second enclosure 122 are nested together to form an air intake chamber 111d. As an example, the second enclosure 122 can be fitted over the first enclosure 113.

[0066] like Figure 3 As shown, the barrier 12 is also provided with an airflow channel 12c, which connects the docking groove 111c and the air inlet chamber 111d. The air inlet chamber 111d can be connected to the outside. During the use of the aerosol generating device, outside air can enter the air inlet chamber 111d, then enter the docking groove 111c through the airflow channel 12c, and then enter the atomizer 200.

[0067] The first enclosure 113 and the second enclosure 122 are interlocked to form an air intake chamber 111d in the groove 111a, which is isolated from the liquid storage chamber 111b. The first enclosure 113 and the second enclosure 122 can serve as an isolation mechanism to prevent liquid flowing into the liquid storage chamber 111b from leaking to the outside through the air intake chamber 111d.

[0068] For example, two airflow channels 12c can be provided, arranged at intervals. The number of airflow channels 12c can be the same as the number of atomizing coils 221 in the atomizer 200. After the atomizer 200 is connected to the power supply 100, the outlet of the airflow channel 12c can face the atomizing coil 221, so that the airflow discharged from the airflow channel 12c can both dissipate heat from the atomizing coil 221 and carry away the aerosol generated at the atomizing coil 221.

[0069] like Figure 4 As shown, the barrier 12 has a first boss 123 on the side near the docking groove 111c, and the airflow channel 12c passes through the top surface of the first boss 123. The first boss 123 can be located between the liquid storage tank 12a and the vertical plate 121.

[0070] The first protrusion 123 is positioned such that the outlet of the airflow channel 12c is higher than the surface of the barrier 12, which can reduce the risk of liquid adhering to the surface of the barrier 12 entering the airflow channel 12c and then entering the air intake chamber 111d through the airflow channel 12c, causing leakage.

[0071] The first protrusion 123 can be set one-to-one with the airflow channel 12c, and each first protrusion 123 is provided with an airflow channel 12c.

[0072] Reference Figure 3 The bracket 11 may further include a battery receiving portion 112, which is connected to the docking portion 111. The battery receiving portion 112 is located on the side of the air guide groove 111e away from the groove 111a. The battery receiving portion 112 has a battery receiving slot for accommodating a battery. The bracket 11 may further include an air inlet pipe 114, which communicates with the air guide groove 111e. Air from outside the aerosol generating device can enter the air guide groove 111e through the air inlet pipe 114.

[0073] like Figure 4 As shown, the support assembly 10 also has an electrode socket 12e, which can pass through the first boss 123 and the docking portion 111. The electrode socket 12e connects the groove 111a and the battery receiving slot. The electrode socket 12e is used to place the electrode 2231 to connect the atomizer 200 and the battery 21.

[0074] In some examples, a flow guide slope 12d may be provided at the opening of the liquid storage tank 12a. The flow guide slope 12d can serve to guide the flow, making it easier for liquid adhering to the surface of the barrier 12 away from the bottom surface of the groove 111a to flow into the liquid storage tank 12a.

[0075] In some examples, the flow guide slope 12d can be arranged around the opening of the liquid storage tank 12a.

[0076] As an example, such as Figure 4 As shown, the guide slope 12d can be located between the side wall of the liquid storage tank 12a near the first protrusion 123 and the first protrusion 123, which promotes the flow of liquid adhering between the first protrusion 123 and the liquid storage tank 12a into the liquid storage tank 12a, and avoids the accumulation of liquid near the first protrusion 123, which would increase the risk of liquid entering the airflow channel 12c.

[0077] like Figure 3 As shown, the docking part 111 is also provided with an air guide groove 111e. The air guide groove 111e is located outside the groove 111a, and the air guide groove 111e is located at the bottom of the groove 111a. The air intake channel 111f connects the air guide groove 111e and the air intake chamber 111d.

[0078] During the use of the aerosol generating device, outside air enters the air guide groove 111e and then enters the air intake chamber 111d through the air intake channel 111f. The air guide groove 111e provides a certain buffering effect to the air intake chamber 111d. When liquid enters the air intake chamber 111d, the air intake chamber 111d can contain a portion of the liquid, thereby reducing the risk of further liquid leakage outside the aerosol generating device.

[0079] In some examples, the bottom of the groove 111a is provided with a second boss 1111, which may be located in the air intake chamber 111d. The air intake passage 111f passes through the top surface of the second boss 1111.

[0080] The second protrusion 1111 is designed such that the inlet of the air intake channel 111f is higher than the inner surface of the air intake chamber 111d, which can reduce the risk of liquid adhering to the inner surface of the air intake chamber 111d entering the air intake channel 111f and entering the air guide groove 111e through the air intake channel 111f, causing leakage.

[0081] In some examples, a fourth liquid-absorbing element 134 may also be provided in the air intake chamber 111d. Exemplarily, the fourth liquid-absorbing element 134 can be absorbent cotton, such as organic cotton, ceramic cotton, bamboo fiber cotton, or composite cotton. The fourth liquid-absorbing element 134 can absorb the liquid entering the air intake chamber 111d from the airflow channel 12c, preventing the liquid from entering the air guide groove 111e from the air intake chamber 111d, which helps to further reduce the risk of leakage of the aerosol generation device.

[0082] like Figure 3 As shown, the position of the barrier 12 opposite the air intake channel 111f may be provided with a guide surface 123a, the guide surface 123a is a concave curved surface, and the guide surface 123a extends to the airflow channel 12c.

[0083] When the airflow enters the intake chamber 111d from the intake channel 111f, the airflow direction is towards the guide surface 123a. Under the action of the guide surface 123a, the airflow can smoothly enter the airflow channel 12c along the guide surface 123a, which helps to reduce airflow resistance.

[0084] Figure 7 This is a schematic diagram of another barrier provided in the embodiments of this application, as shown below. Figure 7 As shown, multiple guide grooves 123b can be provided on the guide surface 123a, and the guide grooves 123b extend from the position of the guide surface 123a directly opposite the air intake channel 111f to the airflow channel 12c.

[0085] By further providing a guide groove 123b on the guide surface 123a, it is beneficial for the airflow to enter the airflow channel 12c more smoothly. And when liquid enters from the outlet of the airflow channel 12c, the guide groove 123b helps the liquid adhere to the guide surface 123a.

[0086] like Figure 3 As shown, the sidewall of the air guide groove 111e may also be provided with an airflow sensor hole 111h. The outer sidewall of the air guide groove 111e may be provided with an airflow sensor mounting groove 111g, and the airflow sensor hole 111h can connect the air guide groove 111e and the airflow sensor mounting groove 111g. During the suction process, the air pressure at the airflow sensor hole 111h will change. The air pressure change can be detected by the airflow sensor 23 installed in the airflow sensor mounting groove 111g, thereby controlling the operation of the atomizer 200.

[0087] Reference Figure 2 As shown, the support assembly 10 may further include a sealing plate 14, which may be located in the air guide groove 111e and is in a sealing fit with the inner wall of the air guide groove 111e. The sealing plate 14 is used to seal the air guide groove 111e.

[0088] For example, the sealing plate 14 can be a silicone sealant.

[0089] Figure 8 This is a schematic diagram of the assembly structure of a power supply provided in an embodiment of this application, as shown below. Figure 8 As shown, the power source 100 may include a battery 21 and, for example, a battery 21 and a battery 21. Figures 2-7 In any of the bracket components 10 shown, the battery 21 is housed in the bracket 11.

[0090] As an example, the power supply 100 may also include a circuit board 22 and an airflow sensor 23. The outer wall of the mating portion 111 may have an airflow sensor mounting groove 111g, with the circuit board 22 located on one side of the bracket assembly 10 and the airflow sensor 23 located in the airflow sensor mounting groove 111g, the airflow sensor 23 being connected to the circuit board 22.

[0091] like Figure 8 As shown, the power supply 100 also includes a display panel 24, which is located on the side of the circuit board 22 away from the airflow sensor 23, and is electrically connected to the circuit board 22.

[0092] The display panel 24 is arranged on one side of the circuit board 22, so that the display panel 24 and the circuit board 22 are arranged in a parallel or nearly parallel manner, which saves space and makes the power supply structure more compact.

[0093] For example, the power supply 100 may also include a housing 30, in which the support assembly 10 is located. The housing 30 may be used to snap onto the atomizer 200.

[0094] Figure 9 This is a schematic diagram of the assembly structure 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 100. The power supply 100 is connected to the atomizer 200. The power supply 100 is used to supply power to the atomizer 200. The power supply 100 can be... Figure 8 The power supply shown is 100.

[0095] Figure 10 This is a schematic diagram of the internal structure of an aerosol generating device provided in an embodiment of this application. Figure 10 As shown, the atomizer 200 includes a liquid storage assembly 210 and an atomizing assembly 220. The liquid storage assembly 210 is used to store the aerosol matrix.

[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] 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.

[0098] like Figure 10 As shown, an atomizing chamber 200a is formed between the atomizer 200 and the barrier 12. The atomizing chamber 200a can be formed between the base 212 and the barrier 12, and the atomizing assembly 220 can be located in the atomizing chamber 200a. The atomizing assembly 220 is used to heat the aerosol matrix to form an aerosol.

[0099] The atomizing assembly 220 may include two atomizing coils 221, which are located in the atomizing chamber 200a. The atomizer 200 has an exhaust channel 212a communicating with the atomizing chamber 200a. The exhaust channel 212a may be disposed on the base 212. One end of the exhaust channel 212a is communicating with the atomizing chamber 200a, and the other end of the exhaust channel 212a is used to communicate with the mouthpiece 201.

[0100] The inlet of the exhaust channel 212a can be located between the two atomizing cores 221. The barrier 12 is provided with two airflow channels 12c, which are arranged in a one-to-one correspondence with the atomizing cores 221.

[0101] The two atomizing cores 221 can be arranged at intervals along the second direction Y. The two airflow channels 12c can also be arranged at intervals along the second direction Y, which means that at least the outlets of the two airflow channels 12c are distributed at intervals along the second direction Y.

[0102] By arranging two airflow channels 12c and two atomizing cores 221, the amount of aerosol released by the aerosol generating device can be increased. Positioning the inlet of the exhaust channel 212a between the two atomizing cores 221 facilitates the convergence of the aerosols generated by the two atomizing cores 221 into the exhaust channel 212a.

[0103] 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 201 through the exhaust channel 212a.

[0104] Figure 11 This is a partial structural schematic diagram of an aerosol generating device provided in an embodiment of this application. Figure 11 The structure near the atomizing chamber 200a is shown, and the direction of airflow is schematically indicated by arrows. Figure 11 As shown, the distance from the geometric center of the projection of the outlet of the airflow channel 12c onto the first surface 221a to the first side 221b is greater than the distance to the second side 221c.

[0105] Wherein, the first surface 221a is the surface of the atomizing core 221 close to the airflow channel 12c, the first side 221b is the side of the first surface 221a close to the inlet of the exhaust channel 212a, and the second side 221c is the side of the first surface 221a away from the inlet of the exhaust channel 212a.

[0106] The projection of the outlet of airflow channel 12c onto the first surface 221a refers to the projection formed by the outlet of airflow channel 12c along the airflow direction at the outlet of airflow channel 12c. If the airflow direction at the outlet of airflow channel 12c is perpendicular to the first surface 221a, then the projection of the outlet of airflow channel 12c onto the first surface 221a refers to the orthographic projection of the outlet of airflow channel 12c onto the first surface 221a.

[0107] Since the geometric center of the projection of the outlet of the airflow channel 12c onto the first surface 221a is closer to the second side 221c, the airflow flowing out of the outlet of the airflow channel 12c acts on the atomizing core 221 closer to the second side 221c, that is, closer to the side of the atomizing core 221 away from the inlet of the exhaust channel 212a, rather than the traditional center position facing the first surface 221a. This allows the airflow to more fully carry away the aerosol in the atomizing chamber 200a.

[0108] like Figure 10 As shown, the atomizing core 221 includes a liquid guiding component 222 and a heating component 223, with the heating component 223 located on the side of the liquid guiding component 222 away from the liquid inlet channel 212b. The aerosol generating device also includes an electrode 2231, which can be inserted into an electrode socket 12e. One end of the electrode 2231 is located in the atomizing chamber 200a and abuts against the heating component 223. The other end of the electrode 2231 is used to connect to the battery 21.

[0109] 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.

[0110] Reference Figure 10 As shown, the atomizer 200 of the aerosol generating device may also include a seal 213, which is located on the side of the base 212 away from the docking part 111. The seal 213 forms a seal with the inner wall of the liquid tank housing 211 to improve the sealing performance of the liquid tank.

[0111] In some examples, the power supply 100 is detachably connected to the atomizer 200. Because the power supply 100 is detachably connected to the atomizer 200, it is easy to replace the atomizer 200.

[0112] In other examples, the power supply 100 and the atomizer 200 may be fixedly connected. For example, the housing of the power supply 100 and the liquid tank housing 211 of the atomizer 200 may be an integral structure.

[0113] Figure 9 and 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.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
