Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomizer, a host and an aerosol generating device. Background Art

[0002] In the prior art, an aerosol generating device mainly includes a main unit and an atomizer. The atomizer can atomize an aerosol generating liquid into an aerosol, and the main unit is used to provide power to the atomizer. In order to facilitate users to replace the atomizer or the main unit, the atomizer and the main unit are usually detachably connected. However, when the atomizer is installed on the main unit, the atomizer and the main unit cannot be automatically aligned in the circumferential direction. The user needs to constantly adjust the relative angle between the atomizer and the main unit so that the electrodes on the atomizer and the electrodes on the main unit can be accurately aligned and electrically connected, which is very inconvenient to install.

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0038] In a first aspect, an embodiment of the present application provides an atomizer to solve the problem that the atomizer and the host in the existing aerosol generating device cannot be automatically aligned, which will be described below with reference to the accompanying drawings.

[0039] In the embodiments of the present application, Figure 1 , Figure 2 or Figure 3 As shown in any of the figures in FIG. 1 , the atomizer 10 is used in conjunction with the host 20, and as Figure 4 As shown, the atomizer 10 includes a housing 11 , on which a first electrode 13 , a first magnetic attraction member 16 and a first positioning structure 17 are provided.

[0040] For the specific structure of the housing 11, please refer to Figure 5 , Figure 5 for Figure 4 In the cross-sectional view of the atomizer 10, an air flow channel 111 and a liquid collecting tank 112 are provided in the shell 11, one end of the air flow channel 111 is connected to the liquid collecting tank 112, and the other end forms a mist outlet 1111, and the liquid collecting tank 112 has a groove bottom 1121 facing the air flow channel 111.

[0041] Specifically, in this embodiment, the shell 11 includes a liquid cup 113, a suction nozzle 114, a base 115 and a mist outlet pipe 116, the suction nozzle 114 is installed on the top of the liquid cup 113, the base 115 is installed on the bottom of the liquid cup 113, and the mist outlet pipe 116 is installed inside the liquid cup 113.

[0042] Among them, the mist outlet pipe 116 and the suction nozzle 114 jointly enclose an air flow channel 111, and the air flow channel 111 forms a mist outlet 1111 at the top of the suction nozzle 114; the mist outlet pipe 116 and the base 115 jointly enclose a liquid collecting tank 112, and the liquid collecting tank 112 is located below the air flow channel 111 and is connected to the air flow channel 111, and the bottom 1121 of the liquid collecting tank 112 is formed by the base 115, and the bottom 1121 faces the air flow channel 111; the outer peripheral wall of the mist outlet pipe 116 and the inner peripheral wall of the liquid cup 113 are spaced to form a liquid storage tank, which is used to store the aerosol generating liquid to be atomized.

[0043] It should be noted here that the suction nozzle 114 can be detachably mounted on the liquid cup 113, or it can be integrally formed with the liquid cup 113; similarly, the mist outlet pipe 116 can be detachably mounted in the liquid cup 113, or it can be integrally formed with the liquid cup 113; the base 115 is used to block the bottom of the liquid cup 113, and in order to improve the sealing performance, a sealing member 19 (such as sealing silica gel, sealing rubber, etc.) can also be provided between the base 115 and the liquid cup 113 to prevent the aerosol generating liquid from leaking out of the gap between the base 115 and the liquid cup 113. Of course, a sealing member 19 can also be provided between the mist outlet pipe 116 and the liquid cup 113, and between the suction nozzle 114 and the liquid cup 113, according to the circumstances, to improve the sealing performance of the entire atomizer 10. In short, the housing 11 of the atomizer 10 can be flexibly designed as needed, as long as a liquid storage bin, an air flow channel 111, and a liquid collecting tank 112 can be formed.

[0044] like Figure 5 As shown, the atomizing core 12 is at least partially located in the air flow channel 111, and the atomizing core 12 is used to atomize the aerosol generating liquid, and the atomized aerosol generating liquid can form an aerosol after mixing with air. Specifically, the atomizing core 12 mainly includes a heating element 121 and a liquid guiding element 122, and the heating element 121 and the liquid guiding element 122 are both tubular structures, and the heating element 121 is coaxially installed in the liquid guiding element 122, and the liquid guiding element 122 is coaxially installed in the air flow channel 111. A liquid suction opening can be set at a position corresponding to the liquid guiding element 122 on the mist outlet pipe 116, or the liquid guiding element 122 can partially pass through the liquid guiding tube and extend into the liquid storage tank, so that the liquid guiding element 122 can guide the aerosol generating liquid in the liquid storage tank to the heating element 121, and then the aerosol generating liquid is heated and atomized by the heating element 121. Therefore, the liquid guide member 122 can be a porous body such as cotton, non-woven fabric, glass fiber, porous ceramic material, porous metal material, etc., so that the aerosol generating liquid in the liquid storage tank can be continuously sucked to the heating member 121 through capillary action. The heating member 121 can be a heating wire, a heating tube, etc., and can heat the aerosol generating liquid into atomized liquid when powered on.

[0045] like Figure 4 and 5 As shown, in order to enable the heating element 121 to heat the aerosol generating liquid by being electrically connected, the atomizer 10 is further provided with a first electrode 13, and the first electrode 13 is used to be electrically connected to the second electrode 21 on the host 20. Specifically, in this embodiment, as shown Figure 4 As shown, Figure 4 This is a three-dimensional schematic diagram of an embodiment of the atomizer 10 of the present application. The first electrode 13 is located on the first assembly end surface 18 of the housing 11, and the first electrode 13 is provided with two. Figure 5 , Figure 5 for Figure 4In the cross-sectional view of the atomizer 10, the two first electrodes 13 are respectively electrically connected to the atomizer core 12 installed in the shell 11 to provide electrical energy to the atomizer core 12 so that the atomizer core 12 can atomize the aerosol generating liquid.

[0046] like Figure 6 As shown, two second electrodes 21 are correspondingly provided on the second assembly end surface 24 of the host 20. Figure 7 As shown, Figure 7 The structure of the main unit 20 is a cross-sectional view. The two second electrodes 21 are electrically connected to the battery 28 installed in the main unit 201 through the circuit control board 327. Figure 8 or Fig. 9 When the atomizer 10 is installed on the host 20, the two first electrodes 13 and the two second electrodes 21 are electrically contacted respectively, so that the electric energy in the battery 28 can be transmitted to the atomizer core 12, so that the atomizer core 12 can atomize the aerosol generating liquid.

[0047] like Figure 4 and Figure 6 As shown, a first magnetic member 16 is provided on the housing 11 of the atomizer 10, and a second magnetic member 22 is provided on the body 201 of the host 20. The first magnetic member 16 is used to magnetically adsorb with the second magnetic member 22 on the host 20, thereby realizing the connection between the atomizer 10 and the host 20. In addition, in the present embodiment, when the atomizer 10 is close to the host 20, the magnetic force between the first magnetic member 16 and the second magnetic member 22 can make the atomizer 10 rotate automatically, so that the first electrode 13 and the second electrode 21 are aligned and connected.

[0048] Specifically, in order to ensure that the magnetic force between the first magnetic member 16 and the second magnetic member 22 can enable the atomizer 10 to rotate automatically, there may be multiple ways to dispose the first magnetic member 16 and the second magnetic member 22 on the atomizer 10 and the host 20 respectively.

[0049] For example, optionally, in one embodiment, Figure 4 As shown, the housing 11 has a first assembly end surface 18. Figure 6 As shown, the body 201 has a second assembly end face 24. During assembly, the first assembly end face 18 is used to be arranged opposite to the second assembly end face 24 on the host 20. In addition, at least one first magnetic attraction member 16 is arranged on the first assembly end face 18, and at least one first magnetic attraction member 16 is arranged eccentrically relative to the rotation center of the first assembly end face 18. A second magnetic attraction member 22 is also arranged on the second assembly end face 24. The second magnetic attraction member 22 is adapted to the first magnetic attraction member 16 in terms of quantity and arrangement position, so that the first magnetic attraction member 16 and the second magnetic attraction member 22 are adsorbed correspondingly.

[0050] It can be understood that because at least one first magnetic component 16 is eccentrically arranged relative to the rotation center of the first assembly end face 18, when the first magnetic component 16 and the second magnetic component 22 are not accurately aligned, the magnetic force generated by the first magnetic component 16 and the second magnetic component 22 can form a torque on the atomizer 10, thereby enabling the atomizer 10 to rotate automatically, thereby achieving automatic alignment of the atomizer 10.

[0051] It should be noted that only one first magnetic member 16 may be provided on the first assembly end face 18, and the first magnetic member 16 is eccentrically arranged relative to the rotation center of the first assembly end face 18. Of course, a plurality of first magnetic members 16 may also be provided on the first assembly end face 18, and at least one of the plurality of first magnetic members 16 may be eccentrically arranged relative to the rotation center of the first assembly end face 18, and the other first magnetic members 16 may be coaxially arranged with the rotation center of the first assembly end face 18, or may be eccentrically arranged.

[0052] For example, optionally, in another embodiment, Figure 4 As shown, the housing 11 has an assembly outer peripheral surface 110, and the body 201 of the host 20 is provided with an installation cavity 261 for installing the atomizer 10, and the installation cavity 261 has an assembly inner peripheral surface 2612, and the assembly outer peripheral surface 110 is used to be arranged opposite to the assembly inner peripheral surface 2612 on the host 20. In addition, at least one first magnetic attraction member 16 is provided on the assembly outer peripheral surface 110, and a second magnetic attraction member 22 is also provided on the assembly inner peripheral surface 2612, and the second magnetic attraction member 22 is adapted to the first magnetic attraction member 16 in terms of quantity and position.

[0053] It can be understood that because the first magnetic member 16 is located on the assembly outer peripheral surface 110 of the atomizer 10, when the first magnetic member 16 and the second magnetic member 22 are not accurately aligned, the magnetic force generated between the first magnetic member 16 and the second magnetic member 22 can form a torque on the atomizer 10, thereby enabling the atomizer 10 to rotate automatically, thereby achieving automatic alignment of the atomizer 10.

[0054] In summary, it can be understood that the atomizer 10 provided in the present application is provided with a first magnetic component 16, and the first magnetic component 16 is used for magnetic adsorption with the second magnetic component 22 on the host 20, and when the atomizer 10 is close to the host 20, the magnetic force between the first magnetic component 16 and the second magnetic component 22 can make the atomizer 10 automatically rotate, and then make the first electrode 13 and the second electrode 21 align and connect, thereby realizing automatic alignment of the atomizer 10 when installed on the host 20, and effectively solving the technical problem that the atomizer 10 and the host 20 in the existing aerosol generating device 100 cannot be automatically aligned.

[0055] In addition, in this embodiment, Figure 4 As shown, the atomizer 10 is also provided with a first positioning structure 17, such as Figure 6 As shown, the host 20 is further provided with a second positioning structure 203, and the first positioning structure 17 is used to be positioned and connected with the second positioning structure 203 on the host 20, so as to limit the relative rotation of the atomizer 10 and the host 20 after the first electrode 13 and the second electrode 21 are aligned and connected. It can be understood that this can improve the installation stability between the atomizer 10 and the host 20, and avoid the situation where the atomizer 10 rotates relative to the host 20, resulting in the disconnection between the first magnetic attraction member 16 and the second magnetic attraction member 22, and between the first electrode 13 and the second electrode 21.

[0056] It should be noted that there may be many schemes for the specific design of the first positioning structure 17 and the second positioning structure 203 .

[0057] For example, in one embodiment, please combine Figure 4 and Figure 6 The first positioning structure 17 includes a positioning groove 171 , and the second positioning structure 203 includes a positioning column 23 , and the positioning groove 171 is plugged and matched with the positioning column 23 .

[0058] Alternatively, in another embodiment, the first positioning structure 17 includes a positioning column 23 , the second positioning structure 203 includes a positioning groove 171 , and the positioning column 23 is plugged into and matched with the positioning groove 171 .

[0059] It should also be noted that the first positioning structure 17 and the first electrode 13 can be two components spaced apart or integrally formed; correspondingly, the second positioning structure 203 and the second electrode 21 can be two components spaced apart or integrally formed.

[0060] For example, in one embodiment, the first positioning structure 17 and the first electrode 13 are spaced apart, and the second positioning structure 203 and the second electrode 21 can be spaced apart. During assembly, the first positioning structure 17 and the first electrode 13 are respectively aligned and connected with the second positioning structure 203 and the second electrode 21, so as to ensure that the electrical connection components and the positioning components do not interfere with each other.

[0061] Alternatively, in another embodiment, the first positioning structure 17 is integrally provided with the first electrode 13, for example, the first positioning structure 17 is a conductive groove recessed on the first electrode 13, and correspondingly, the second positioning structure 203 is also integrally provided with the second electrode 21, for example, the second positioning structure 203 is a conductive protrusion convexly provided on the second electrode 21. During assembly, the conductive groove on the first electrode 13 and the conductive protrusion on the second electrode 21 are plugged into each other, and are electrically connected and positioned at the same time, which can simplify the structure of the atomizer 10 and the host 20.

[0062] Optionally, in one embodiment, please combine Figure 4 and Figure 5, Figure 4 This is a three-dimensional schematic diagram of an embodiment of the atomizer of the present application. Figure 5 for Figure 4 In the cross-sectional view of the atomizer in FIG. 1 , the first electrode 13 is installed on the side of the housing 11 away from the mist outlet 1111 , and the first electrode 13 also partially extends into the liquid collecting tank 112 and protrudes relative to the tank bottom 1121 .

[0063] Specifically, in this embodiment, the first electrode 13 includes a mounting portion 131 and a leak-proof protrusion 132 connected to each other. The mounting portion 131 is mounted on the side of the housing 11 away from the mist outlet 1111, specifically, it is snap-fitted on the base 115, and the leak-proof protrusion 132 is connected to the side of the mounting portion 131 close to the liquid collecting tank 112, and the leak-proof protrusion 132 passes through the bottom 1121 of the liquid collecting tank 112 and extends into the liquid collecting tank 112, that is, the leak-proof protrusion 132 protrudes relative to the bottom 1121 of the liquid collecting tank 112. The first electrode 13 is electrically connected to the atomizer core 12. Specifically, the heater 121 in the atomizer core 12 can be electrically contacted with the leak-proof protrusion 132 or the mounting portion 131 of the first electrode 13 through a metal pin.

[0064] Key, such as Figure 5 As shown, in this embodiment, the first electrode 13 is penetrated with an air inlet 14, which can avoid the situation that the atomizer 10 is larger in size when the first electrode 13 and the air inlet 14 are separately provided, so that the structure of the atomizer 10 is more compact. The air inlet 14 penetrates the mounting portion 131 and the anti-leakage protrusion 132 at the same time, and the air inlet 14 has an outer air port 141 and an inner air port 142 relative to each other. The outer air port 141 is located on the mounting portion 131 and communicates with the external environment of the housing 11, and the inner air port 142 is located at the end of the anti-leakage protrusion 132 away from the mounting portion 131, and then in the depth direction of the liquid collecting tank 112 (i.e. Figure 5 In the up-down direction), the position of the inner air port 142 is higher than the groove bottom 1121.

[0065] Therefore, when the user inhales through the nozzle 114, the air outside the atomizer 10 will enter the liquid collecting tank 112 and the air flow channel 111 through the air inlet 14. At this time, the atomizing core 12 will simultaneously atomize the aerosol generating liquid. The atomized aerosol generating liquid is mixed with air to form an aerosol, and then the aerosol flows out through the mist outlet 1111 under the action of the suction force.

[0066] Since the duration and strength of the user's inhalation are random, some aerosol-generating liquid at the atomizing core 12 may not be atomized in time, and the aerosol-generating liquid that is not atomized will drip into the liquid collecting tank 112. If the inner air port 142 of the air inlet 14 is flush with or lower than the bottom 1121 of the liquid collecting tank 112, the aerosol-generating liquid will easily flow out of the air inlet 14 and cause leakage. Therefore, in the present application, the position of the inner air port 142 is also made higher than the bottom 1121, so that the aerosol-generating liquid that drips into the liquid collecting tank 112 cannot flow out of the air inlet 14, effectively solving the technical problem that the aerosol-generating liquid in the existing atomizer 10 is easy to leak from its air inlet 14.

[0067] Optionally, in one embodiment, as Figure 5 As shown, the atomizer core 12 has an atomization channel 123, and the atomization channel 123 is coaxially connected to the air flow channel 111. Specifically, as described above, the atomizer core 12 in this embodiment includes a heating element 121 and a liquid guiding element 122. The heating element 121 and the liquid guiding element 122 are both hollow tubular. The liquid guiding element 122 is coaxially installed in the air flow channel 111, and the heating element 121 is coaxially installed in the liquid guiding element 122. The channel formed in the heating element 121 is the atomization channel 123.

[0068] And in this embodiment, in order to prevent the aerosol generating liquid from directly dripping into the inner air port 142 of the air inlet 14, in the axial direction of the air flow channel 111 (i.e., the up and down direction in the figure), the projections of the atomization channel 123 and the inner air port 142 on the groove bottom 1121 do not overlap each other. Specifically, two first electrodes 13 are provided, and the two first electrodes 13 are arranged symmetrically about the central axis of the atomization channel 123, so there are also two inner air ports 142, and the two inner air ports 142 are also arranged symmetrically about the atomization channel 123. When the atomization channel 123 and the two inner air ports 142 are projected onto the groove bottom 1121 of the liquid collecting tank 112, the projections of the two inner air ports 142 are respectively located on the left and right sides of the projection of the atomization channel 123. That is, the air inlet 14 and the atomization channel 123 are not arranged in vertical alignment, but are staggered with each other, so as to avoid the aerosol generating liquid from the atomization channel 123 directly dripping into the air inlet 14.

[0069] It should be noted here that because the atomization channel 123 and the inner air port 142 themselves are virtual bodies, when the atomization channel 123 and the inner air port 142 are projected onto the bottom 1121 of the liquid collecting tank 112, they actually enclose the inner wall of the atomization channel 123 (i.e., the inner wall of the heating element 121) and the inner wall of the inner air port 142 (i.e., the inner wall of the air inlet hole) respectively projected onto the bottom 1121. In the present embodiment, the projection of the inner wall of the atomization channel 123 on the bottom 1121 and the projection of the inner wall of the inner air port 142 on the bottom 1121 are respectively located in different areas, and the two do not overlap with each other.

[0070] Of course, in other embodiments, the air inlet 14 and the atomization channel 123 may also be arranged relative to each other up and down. In this case, as long as a blocking member is arranged above the inner air port 142 , the blocking member can block the aerosol generating liquid and prevent the aerosol generating liquid from directly dripping into the air inlet 14 .

[0071] Optionally, in one embodiment, as Figure 5 As shown, the atomizer core 12 includes a heating element 121 and a liquid guide element 122. A liquid absorbent element 15 is also provided in the liquid collecting tank 112. The material of the liquid absorbent element 15 can be a porous body such as cotton, non-woven fabric, glass fiber, porous ceramic material, porous metal material, etc., so that the aerosol generating liquid in the liquid collecting tank 112 can be absorbed by the liquid absorbent element 15, and the aerosol generating liquid can be further prevented from leaking from other positions.

[0072] When the absorbent member 15 is installed in the liquid collecting tank 112, the absorbent member 15 can be installed in a variety of ways. For example, in one embodiment, the absorbent member 15 is installed independently of the liquid guiding member 122, which makes it easier to assemble. Alternatively, in another embodiment, the absorbent member 15 is at least partially attached to the liquid guiding member 122, so that the liquid guiding member 122 can absorb the aerosol generating liquid on the absorbent member 15 to the heating member 121, thereby achieving efficient use of the aerosol generating liquid. Alternatively, the absorbent member 15 can also be integrally arranged with the liquid guiding member 122, so as to avoid the situation where the aerosol generating liquid cannot be efficiently used due to unstable contact between the absorbent member 15 and the liquid guiding member 122. In short, the installation method of the absorbent member 15 can be flexibly selected according to needs, and no specific limitation is made here.

[0073] Second, as Figure 6 As shown, the present application further proposes a host 20 , which is used in conjunction with the atomizer 10 , and includes a body 201 , on which a second electrode 21 , a second magnetic attraction member 22 and a second positioning structure 203 are provided.

[0074] The second electrode 21 is used to be electrically connected to the first electrode 13 on the atomizer 10. For details, please refer to the above description of the first electrode 13 and the second electrode 21. Figure 6 , Figure 7 or Figure 8 The host 20 is provided with a second electrode 21, and the host 20 is provided with a circuit control board 27 and a battery 28. The second electrode 21 is a retractable metal spring pin, and one end of the second electrode 21 extends out of the host 20 so as to be able to electrically contact the first electrode 13 on the atomizer 10, and the other end is located in the host 20 and installed on the circuit control board. The circuit control board 27 is electrically connected to the battery 28, and then the battery 28 can provide electrical energy to the atomizer 10 through the first electrode 13 and the second electrode 21, so that the atomizer 10 can atomize the aerosol generating liquid. Since the aerosol generating device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0075] Among them, you can refer to Figure 7 or Figure 7 The host 20 is generally provided with a microphone 29, a charging control board 210 and a charging interface 211. The microphone 29 is installed on the circuit control board 27, and the microphone 29 detects the airflow conditions at the air inlet 14 through the airflow detection channel 291, such as the flow rate, flow rate, etc. of the airflow, and then controls the output power of the circuit control board 27 according to the airflow conditions at the air inlet 14, so that the atomization core 12 can atomize the aerosol generating liquid in time when the user inhales. The charging control board 210 is installed on the side of the battery 28 away from the circuit control board 27, and the charging interface 211 is connected to the charging control board 210, which is not only convenient for charging the host 20, but also can control the charging process of the battery 28 to avoid overcharging.

[0076] The second magnetic member 22 is used to magnetically attract the first magnetic member 16 on the atomizer 10, and when the atomizer 10 is close to the host 20, the magnetic force between the first magnetic member 16 and the second magnetic member 22 causes the atomizer 10 to automatically rotate, so that the first electrode 13 and the second electrode 21 are aligned and connected. Similarly, here, you can refer to the relevant introduction about "the magnetism of the first magnetic member 16 and the second magnetic member 22" in the previous text, and will not repeat it here.

[0077] For example, optionally, in one embodiment, the body 201 has a second assembly end face 24, which is used to be arranged opposite to the first assembly end face 18 on the atomizer 10, and at least one second magnetic component 22 is provided on the second assembly end face 24, and at least one second magnetic component 22 is eccentrically arranged relative to the rotation center of the second assembly end face 24, so that when the second magnetic component 22 generates magnetic force with the first magnetic component 16 arranged on the first assembly end face 18, the atomizer 10 can rotate automatically.

[0078] Alternatively, in another embodiment, the body 201 has an installation cavity 261, and the installation cavity 261 has an assembly inner circumferential surface 2612, and the assembly inner circumferential surface 2612 is used to be arranged opposite to the assembly outer circumferential surface 110 on the atomizer 10, and at least one second magnetic attraction component 22 is provided on the assembly inner circumferential surface 2612, so that when the second magnetic attraction component 22 generates magnetic force with the first magnetic attraction component 16 arranged on the assembly outer circumferential surface 110, the atomizer 10 can rotate automatically.

[0079] It can be understood that the host 20 provided in the present application is provided with a second magnetic component 22, and the second magnetic component 22 is used for magnetic adsorption with the first magnetic component 16 on the atomizer 10, and when the atomizer 10 is close to the host 20, the magnetic force between the first magnetic component 16 and the second magnetic component 22 can make the atomizer 10 automatically rotate, and then make the first electrode 13 and the second electrode 21 aligned and connected, thereby realizing automatic alignment of the atomizer 10 when installed on the host 20, and effectively solving the technical problem that the atomizer 10 and the host 20 in the existing aerosol generating device 100 cannot be automatically aligned.

[0080] Furthermore, the host 20 of the present application is also provided with a second positioning structure 203, which is used to be positioned and connected with the first positioning structure 17 on the atomizer 10, so as to limit the relative rotation of the atomizer 10 and the host 20 after the first electrode 13 and the second electrode 21 are aligned and connected. Similarly, here, reference can be made to the relevant introduction about the "first positioning structure 17 and the second positioning structure 203" in the previous text, and no further description will be given here.

[0081] For example, optionally, in one embodiment, the second positioning structure 203 includes a positioning groove 171 , and the positioning groove 171 is used to be plugged and matched with the positioning column 23 in the first positioning structure 17 .

[0082] Alternatively, in another embodiment, the second positioning structure 203 includes a positioning post 23 , and the positioning post 23 is used to be plugged and matched with the positioning groove 171 in the first positioning structure 17 .

[0083] For another example, in one embodiment, the second positioning structure 203 is spaced apart from the second electrode 21 so as to be aligned and connected to the first positioning structure 17 and the first electrode 13 spaced apart on the atomizer 10 , respectively.

[0084] Alternatively, in another embodiment, the second positioning structure 203 is integrally provided with the second electrode 21 to be electrically and positionally connected to the first positioning structure 17 and the first electrode 13 integrally provided on the atomizer 10 .

[0085] It can be understood that by providing the second positioning structure 203 on the host 20, the second positioning structure 203 is used to position and connect with the first positioning structure 17 on the atomizer 10, so as to limit the relative rotation of the atomizer 10 and the host 20 after the first electrode 13 and the second electrode 21 are aligned and connected. In this way, the installation stability between the atomizer 10 and the host 20 can be improved, and the situation that the atomizer 10 rotates relative to the host 20 and causes the first magnetic member 16 and the second magnetic member 22, and the first electrode 13 and the second electrode 21 to be disconnected can be avoided.

[0086] Thirdly, Figure 1 , Figure 2 or Figure 3 As shown, the present application also proposes an aerosol generating device 100 , which includes a main atomizer 10 and a host 20 .

[0087] The atomizer 10 is provided with a first electrode 13, a first magnetic member 16 and a first positioning structure 17; the body 201 is provided with a second electrode 21, a second magnetic member 22 and a second positioning structure 203. The first electrode 13 is electrically connected to the second electrode 21, the first magnetic member 16 is magnetically attracted to the second magnetic member 22, and when the atomizer 10 is close to the host 20, the magnetic force between the first magnetic member 16 and the second magnetic member 22 causes the atomizer 10 to rotate automatically so that the first electrode 13 and the second electrode 21 are aligned and connected. The first positioning structure 17 is positioned and connected with the second positioning structure 203, so as to limit the relative rotation of the atomizer 10 and the host 20 after the first electrode 13 and the second electrode 21 are aligned and connected.

[0088] It should be noted that, for the specific cooperation between the atomizer 10 and the host 20, please refer to the above-mentioned introduction about "atomizer 10" and "host 20", which will not be repeated here.

[0089] It can be understood that the aerosol generating device 100 provided in the present application is provided with a first magnetic component 16 on the atomizer 10 and a second magnetic component 22 on the main unit 20. The first magnetic component 16 and the second magnetic component 22 are magnetically attracted to each other. When the atomizer 10 is close to the main unit 20, the magnetic force between the first magnetic component 16 and the second magnetic component 22 can make the atomizer 10 rotate automatically, thereby making the first electrode 13 and the second electrode 21 aligned and connected, thereby realizing automatic alignment of the atomizer 10 when it is installed on the main unit 20, and effectively solving the technical problem that the atomizer 10 and the main unit 20 in the existing aerosol generating device 100 cannot be automatically aligned.

[0090] Regarding the positioning between the atomizer 10 and the host 20, optionally, in one embodiment, one of the host 20 and the atomizer 10 is further provided with a positioning column 23, and the other is provided with a positioning groove 171, and the positioning column 23 is inserted into the positioning groove 171; wherein, the positioning column 23 is inserted into the positioning groove 171 along its own axial direction, and a guide cone 233 is formed on the outer periphery of the positioning column 23.

[0091] Specifically, in Figure 4 and Figure 6 In the structural scheme shown, a positioning column 23 is provided on the main unit 20, and a positioning groove 171 is provided on the atomizer 10. The axial directions of the positioning column 23 and the positioning groove 171 are parallel to the axial direction of the air flow channel 111. When the atomizer 10 is installed on the main unit 20, the positioning column 23 is inserted into the positioning groove 171, thereby limiting the rotation of the atomizer 10 relative to the main unit 20, thereby ensuring the installation stability of the atomizer 10.

[0092] It should be noted here that when the cross-sections of the positioning column 23 and the positioning groove 171 are both circular, the positioning column 23 and the positioning groove 171 need to be provided with multiple, and the multiple positioning columns 23 and the multiple positioning grooves 171 are plugged in one-to-one, so that the relative rotation of the atomizer 10 and the host 20 can be restricted by the positioning column 23 and the positioning groove 171. Alternatively, in another embodiment, the cross-sections of the positioning column 23 and the positioning groove 171 are both elliptical or polygonal, for example, when the positioning column 23 is a quadrangular column, the positioning groove 171 is also adapted to be set as a square groove, so that the positioning of the atomizer 10 and the host 20 can be achieved with only one positioning column 23 and one positioning groove 171.

[0093] For further information, please refer to Figure 6 The atomizer 10 is assembled to the main unit 20 along the axial direction of the positioning column 23. The outer periphery of the positioning column 23 is formed with a guide cone 233, that is, the positioning column 23 is a cone structure, specifically a cone or a multi-faceted cone. It can be understood that the guide cone 233 can play a certain guiding role for the atomizer 10 when the atomizer 10 is assembled to the main unit 20, thereby improving the assembly efficiency.

[0094] Alternatively, in another embodiment, the positioning column 23 has a first end 231 and a second end 232 opposite to each other along its axial direction, and the cross-sectional area of ​​the first end 231 is smaller than the cross-sectional area of ​​the positioning groove 171 so that the first end 231 can enter the positioning groove 171; the cross-sectional area of ​​the second end 232 is larger than the cross-sectional area of ​​the positioning groove 171 so as to limit the second end 232 from entering the positioning groove 171.

[0095] Specifically, taking the case where the cross-sections of the positioning column 23 and the positioning groove 171 at any position are both circular, at this time, the outer diameter of the first end 231 of the positioning column 23 is smaller than the inner diameter of the positioning groove 171, and the outer diameter of the second end 232 is larger than the inner diameter of the positioning groove 171. In this way, the notch of the positioning groove 171 can be stuck between the first end 231 and the second end 232 of the positioning column 23 during assembly, avoiding the situation where the atomizer 10 can shake due to a gap between the positioning groove 171 and the positioning column 23, so that the positioning of the atomizer 10 is more stable.

[0096] Optionally, in one embodiment, please combine Figure 4 , Figure 6 and Fig. 9 The atomizer 10 is provided with a first assembly end surface 18, which is actually the bottom surface of the atomizer 10, and the first electrode 13, the first magnetic member 16 and the positioning groove 171 are all arranged on the first assembly end surface 18. The host 20 has a second assembly end surface 24 facing the first assembly end surface 18, and the second electrode 21, the second magnetic member 22 and the positioning column 23 are all arranged on the second assembly end surface 24. Fig. 9 As shown, after the atomizer 10 is mounted on the main unit 20, a first air inlet gap 30 is formed between the first assembly end face 18 and the second assembly end face 24, and the outer air port 141 of the air inlet hole 14 is connected to the first air inlet gap 30. The main unit 20 is also provided with an air inlet 25 connected to the first air inlet gap 30. When the user inhales through the mouthpiece 114, the air outside the aerosol generating device 100 passes through the air inlet 25, the first air inlet gap 30, the outer air port 141, the air inlet hole 14, the inner air port 142, the liquid collecting tank 112 and the air flow channel 111 in sequence, and finally flows out from the mist outlet 1111 mixed with the aerosol generating liquid after atomization.

[0097] It can be understood that in this embodiment, the first air inlet gap 30 is formed between the first assembly end face 18 and the second assembly end face 24, so that the air inlet hole 14 can inhale air from the first air inlet gap 30. In this way, there is no need to open an additional blocking air inlet passage, which is conducive to simplifying the structure of the aerosol generating device 100 and reducing the difficulty and cost of production.

[0098] It should be noted that the air inlet 25 on the main unit 20 can be relatively connected to the first air inlet gap 30 along the radial direction of the main unit 20. However, in such a design, if the aerosol generating liquid leaks into the first air inlet gap 30, the aerosol generating liquid may leak out of the main unit 20 from the air inlet 25, affecting the user experience. Therefore, in order to solve the above problem, optionally, in one embodiment, as Figure 6 or Figure 7 As shown, the host 20 has an installation cavity 261, and the bottom of the installation cavity 261 forms the second assembly end face 24. Specifically, the host 20 includes a tubular housing 26. After the battery 28, the circuit control board 27, the microphone 29 and other components are installed in the housing 26, the unfilled part of the housing 26 forms the installation cavity 261 for installing the atomizer 10, and the bottom of the installation cavity 261 is the second assembly end face 24. Figure 8 and Fig. 9 As shown, the atomizer 10 is partially inserted into the mounting cavity 261, and the outer circumference of the atomizer 10 and the inner circumference of the main unit 20 are spaced to form a second air inlet gap 40. In the length direction of the main unit 20, the air inlet 25 and the first air inlet gap 30 are staggered. Specifically, the air inlet hole 14 is arranged close to the cavity opening 2611 of the mounting cavity 261, and the air inlet 25 is connected to the first air inlet gap 30 through the second air inlet gap 40, so that the aerosol generating liquid leaked into the first air inlet gap 30 can be prevented from further leaking from the air inlet 25.
