[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0040] Referring to Figures 1 to 4 , the aerosol generating device provided by the embodiments of the present application will now be described. The aerosol generating device includes a housing 10, a switching structure 20, a control component 30, and an operation unit 40. A first air passage 101 and a second air passage 102 that are independent of each other are provided in the housing 10. The first air passage 101 and the second air passage 102 are both vertically arranged and spaced apart from each other, and the airflows flowing in the two air passages do not interfere with each other. A mouthpiece may be provided at the top of the housing 10, and the user can perform a suction action at the mouthpiece. The aerosol generating device has two independent atomization systems. According to the opening and closing conditions of the first air passage 101 and the second air passage 102, the corresponding atomization system is activated. After the corresponding atomization system is activated, it can atomize the aerosol generating substrate, and the aerosol formed after atomization is then sucked out from the mouthpiece, so that the amount of aerosol can be adjusted; further, two aerosol generating substrates with different flavors are stored in the housing 10. The above two aerosol generating substrates correspond to the above two independent atomization systems. According to the opening and closing conditions of the first air passage 101 and the second air passage 102, the corresponding atomization system is activated, and the aerosol generating substrate with the corresponding flavor is atomized accordingly, so as to realize the switching of different flavors of aerosol in the same aerosol atomization device.

[0041] Referring to Figures 4 to 7 , the switching structure 20 includes a movable member 22 and a driving mechanism 21. The movable member 22 is movably arranged at the bottom position inside the housing 10. An air inlet hole 220 is provided on the movable member 22, and through the air inlet hole 220, outside air can enter the inside of the housing 10 to participate in the heating and atomization operation of the atomization component on the aerosol generating substrate. The driving mechanism 21 is used to drive the movable member 22 to move between multiple working positions inside the housing 10, thereby controlling the communication or closing of the air inlet hole 220 with the first air passage 101 and / or the second air passage 102, so as to realize the switching between the two air passages.

[0042] Specifically, the driving mechanism 21 can drive the movable member 22 to move relative to the housing 10 in a straight line between a first working position, a second working position, and a third working position arranged in sequence. When the driving mechanism 21 drives the movable member 22 to move to the first working position, the air inlet hole 220 is communicated with the first air passage 101, and the air inlet hole 220 is closed with the second air passage 102. At this time, the first air passage 101 is opened and the second air passage 102 is closed, and the outside air flow can enter the first air passage 101 through the air inlet hole 220. When the driving mechanism 21 drives the movable member 22 to move to the second working position, the air inlet hole 220 is communicated with the first air passage 101 and the second air passage 102 respectively. At this time, both the first air passage 101 and the second air passage 102 are opened, and the outside air flow can enter the first air passage 101 and the second air passage 102 through the air inlet hole 220. When the driving mechanism 21 drives the movable member 22 to move to the third working position, the air inlet hole 220 is closed with the first air passage 101, and the air inlet hole 220 is communicated with the second air passage 102. At this time, the first air passage 101 is closed and the second air passage 102 is opened, and the outside air flow can enter the second air passage 102 through the air inlet hole 220. In an embodiment, the movable member 22 can also move to a fourth working position. When the driving mechanism 21 drives the movable member 22 to move to the fourth working position, the air inlet hole 220 is closed with the first air passage 101 and the second air passage 102. At this time, both air passages are in a closed state.

[0043] Referring to Figures 4 to 8 , the control assembly 30 is arranged in the housing 10. The control assembly 30 can provide power for the atomization assembly and the driving mechanism 21. The control assembly 30 is communicatively connected with the driving mechanism 21 to control the driving mechanism 21 to drive the movable member 22 to move in the housing 10. The operation part 40 is arranged on the housing 10. The operation part 40 is connected with the control assembly 30. After the operation part 40 is operated, a control signal is transmitted to the control assembly 30. The control assembly 30 controls the driving mechanism 21 to perform a corresponding action, so that the driving mechanism 21 drives the movable member 22 to move from one of the multiple working positions to another of the multiple working positions. That is, each time the operation part is operated, the movable member moves from the current working position to the next working position, and the driving mechanism stops driving the movable member, thereby realizing the opening or closing of the corresponding air passage, that is, realizing the switching action of the air passage.

[0044] Understandably, the operation part 40 can be a control button, a touch button provided on the display screen, or other hardware switches provided on the housing. Adopting this structure can effectively reduce the difficulty of pressing keys and the risk of key jamming during user operation; it solves the problem that different people have different strengths, and different difficulties will be generated for fingers and nails during the process of toggling a physical dial or slide key; the switching airway method achieved by using the operation part 40 to transmit a control signal to the control component 30 improves the convenience of user operation and enhances the user experience. That is to say, the manual operation of a physical mechanical dial or slide key is replaced by an electric drive method, which reduces the difficulty of pressing keys and the risk of key jamming, brings convenience to use, and there is no need to flip the product to confirm or view the moving direction of the movable part 22 during operation. In an embodiment, the operation part 40 is a control button provided at the bottom of the housing 10. When the operation part 40 is pressed for the first time, the driving mechanism 21 drives the movable part 22 to move to the first working position, the first airway 101 is opened, and the second airway 102 is closed; when the operation part 40 is pressed for the second time, the driving mechanism 21 drives the movable part 22 to move to the second working position, and both the first airway 101 and the second airway 102 are opened; when the operation part 40 is pressed for the third time, the driving mechanism 21 drives the movable part 22 to move to the third working position, the first airway 101 is closed, and the second airway 102 is opened; when the operation part 40 is pressed for the fourth time, the driving mechanism 21 drives the movable part 22 to move to the fourth working position, and both the first airway 101 and the second airway 102 are closed.

[0045] Compared with the prior art, the aerosol generating device provided by the present application transmits a control signal to the control component 30 through the pressing operation of the operation part 40. The control component 30 controls the driving mechanism 21 to drive the movable part 22 to move between multiple working positions, so that the air inlet holes 220 on the movable part 22 are connected to and / or closed with the first airway 101 and the second airway 102, thereby realizing the switching of the airway, solving the problem that different users have different operation strengths, and different difficulties are generated for fingers and nails during the process of toggling a physical mechanical key, and avoiding the risk of key jamming. This airway switching method provides the convenience of operation and enhances the user's use experience.

[0046] Refer to Figure 4 、 Figure 6 As shown in

[0047] Refer to Figure 2 、 Figure 4, the housing 10 includes an outer shell 14 and a bottom cover 15 connected to the bottom of the outer shell 14. The bottom cover 15 is installed at the bottom of the outer shell 14 by snap connection. A suction nozzle 50 is provided at the middle position of the top of the outer shell 14. An inner shell 16 is provided above the bracket 11 in the outer shell 14. The inner shell 16 has two liquid storage chambers arranged symmetrically left and right. The aerosol generating matrixes are stored in the left and right liquid storage chambers respectively. In this embodiment, liquid storage cotton 18 is placed in the liquid storage chamber, and the aerosol generating matrix in a liquid state is infiltrated in the liquid storage cotton 18; further, the liquid storage cotton 18 on the left and right sides can store aerosol generating matrixes with different flavors respectively.

[0048] The aerosol generating device includes two atomization components 17, and the two atomization components 17 are arranged symmetrically left and right in the housing 10. Each atomization component 17 includes a diversion tube 170, a heating element 171 and a liquid guiding member 172. The diversion tube 170 is configured to form a first air flow channel 1701. The suction nozzle 50 has a second air flow channel 51 that communicates the first air flow channel 1701 with the outside of the aerosol generating device. The diversion tube 170 penetrates through the liquid storage cotton 18. The heating element 171 is provided on the diversion tube 170. The heating element 171 is provided with a first electrode 173. One end of the liquid guiding member 172 is connected to the heating element 171, and the other end of the liquid guiding member 172 extends into the liquid storage cotton 18 to conduct the aerosol generating matrix of the liquid storage cotton 18 to the heating element 171. The aerosol generating matrix is heated by the heating element 171 to be atomized and form an aerosol. The aerosol flows through the first air flow channel 1701 and the second air flow channel 51 to the suction nozzle 50, and finally flows out of the aerosol generating device.

[0049] Refer to Figures 4 to 6 , Figure 9 and Figure 10, two independent mounting cavities 110 are provided at the top of the bracket 11. An air outlet 103 is provided at the corner of one of the air passages corresponding to the lower part of the mounting cavity 110. Through the air outlet 103, the air passage can be communicated with the corresponding first air flow channel 1701 through the mounting cavity 110. An air flow sensing assembly 19 is further provided on the bracket 11. The air flow sensing assembly 19 includes an electronic control board 190 and an air flow sensor 191 provided on the electronic control board 190. The electronic control board 190 is electrically connected to the control assembly 30. The sensing membranes at the top of the air flow sensor 191 respectively extend into the two mounting cavities 110 on both sides of the top of the bracket 11. Second electrodes 192 are respectively provided on the left and right sides of the electronic control board 190. By contacting the first electrode 173 through the second electrode 192, it is electrically connected to the corresponding atomization assembly 17. The air flow sensor 191 responds by sensing the air pressure change in the mounting cavity 110, triggering the control circuit, so that the corresponding heating element 171 starts to work, generating aerosol for inhalation. A lower sealing silica gel 104 is provided between the liquid storage cotton 18 and the bracket 11. The lower sealing silica gel 104 is hermetically connected to the liquid storage cotton 18. A part of the lower sealing silica gel 104 extends into the mounting cavity 110 at the top of the bracket 11 and is in sealing contact with the inner side wall of the mounting cavity 110. The bottom end of the diversion tube 170 of the atomization assembly 17 passes through the lower sealing silica gel 104 and extends into the mounting cavity 110. An upper sealing silica gel 105 is provided above the inner shell 16. An installation seat 106 is sleeved outside the upper sealing silica gel 105. Through holes are provided at the corresponding positions of the installation seat 106 and the upper sealing silica gel 105, so that the first air flow channel 1701 formed by the diversion tube 170 is communicated with the second air flow channel 51 of the mouthpiece 50.

[0050] Refer to Figures 11 to 14, the movable member 22 includes a first air regulating plate 221 and a second air regulating plate 222 which are arranged in parallel at intervals. The air inlet hole 220 includes at least one first through hole 2210 formed on the first air regulating plate 221 and at least one second through hole 2220 formed on the second air regulating plate 222. The external air flow can be communicated with the first air passage 101 through the first through hole 2210, and the external air flow can be communicated with the second air passage 102 through the second through hole 2220. The driving mechanism 21 is used to drive the first air regulating plate 221 and the second air regulating plate 222 to move linearly relative to the housing 10. Specifically, both the first air regulating plate 221 and the second air regulating plate 222 are generally rectangular plates, and the four corners are smoothly transitioned. Three first through holes 2210 are formed on the first air regulating plate 221, and the diameters of the first through holes 2210 are equal. Three second through holes 2220 are formed on the second air regulating plate 222, and the diameters of the second through holes 2220 are equal. The diameter of the first through hole 2210 is set to be equal to the diameter of the second through hole 2220. The driving mechanism 21 can drive the first air regulating plate 221 and the second air regulating plate 222 to linearly move back and forth along the width direction of the housing 10, thereby changing the communication area between the first air passage 101 and the outside and the communication area between the second air passage 102 and the outside, so as to meet the user's needs for different suction resistances and improve the suction experience. It can be understood that the diameters of the first through holes 2210 on the first air regulating plate 221 can also be set to be unequal, and the diameters of the second through holes 2220 on the second air regulating plate 222 can also be set to be unequal. By providing two movable air regulating plates, through holes are formed on each air regulating plate, and electric power is used to drive the movement of the air regulating plates to realize airway switching. Compared with the traditional airway switching structure using a dial key, the number of cooperating components is reduced, and the number of openings is also reduced, making the product appearance more complete.

[0051] The driving mechanism 21 includes at least one lead screw, at least one lead screw nut 213 and a power source 214. The lead screw nut 213 is screwed onto the lead screw. Both the first air regulating plate 221 and the second air regulating plate 222 are fixedly connected to the lead screw nut 213. The power source 214 drives the lead screw to rotate around its central axis, driving the lead screw nut 213 to move linearly, and then driving the first air regulating plate 221 and the second air regulating plate 222 to move back and forth, realizing the switching of the airways.

[0052] Specifically, please refer to Figure 10 , Figure 12 and Figure 14, the driving mechanism 21 includes a first lead screw 211, a second lead screw 212, four lead screw nuts 213, and a power source 214. Two spaced-apart lead screw nuts 213 are respectively screwed onto the first lead screw 211 and the second lead screw 212. Two of the lead screw nuts 213 are arranged side by side, and the other two lead screw nuts 213 are also arranged side by side. Both ends of the air regulating plate are respectively connected and fixed to two of the lead screw nuts 213 arranged side by side in one group, and both ends of the second air regulating plate 222 are respectively connected and fixed to the other two lead screw nuts 213 arranged side by side in the other group. The power source 214 is used to drive the first lead screw 211 and the second lead screw 212 to rotate synchronously. Specifically, the power source 214 can adopt a single motor 215 to drive the first lead screw 211 and the second lead screw 212 to rotate synchronously at the same time, or can respectively adopt one or more motors 215 to drive the first lead screw 211 and the second lead screw 212 respectively to achieve synchronous rotation. As Figure 8 , Figure 10 and Figure 14 shown, after pressing the operation part 40, the first air regulating plate 221 and the second air regulating plate 222 move synchronously to the same side of the housing 10. The first through hole 2210 on the first air regulating plate 221 communicates with the first air passage 101, and the second through hole 2220 on the second air regulating plate 222 does not communicate with the second air passage 102. At this time, the first air passage 101 is opened, and the second air passage 102 is closed; when the operation part 40 is pressed again, the first air regulating plate 221 and the second air regulating plate 222 move synchronously to the other side of the housing 10. At this time, the first air passage 101 is closed, and the second air passage 102 is opened.

[0053] Specifically, each lead screw nut 213 is generally rectangular in shape as a whole. Both the first air regulating plate 221 and the second air regulating plate 222 are connected and fixed to each lead screw nut 213 by screws 216. It can be understood that the driving mechanism 21 can also be driven by a lead screw and a slide bar arranged in parallel at intervals. Two lead screw nuts are spaced-apart and screwed onto the lead screw, and two sliders are slidably assembled on the slide bar at intervals. Both ends of the first air regulating plate 221 are respectively connected and fixed to a lead screw nut and a slider, and both ends of the second air regulating plate 222 are respectively connected and fixed to the other lead screw nut and the other slider. In this way, when the power source 214 drives the lead screw to rotate, it can also drive the first air regulating plate 221 and the second air regulating plate 222 to make linear movements.

[0054] Refer to Figure 8 , Figure 11 and Figure 14, the power source 214 includes a motor 215 disposed between the first lead screw 211 and the second lead screw 212.
