Aerosol generation device

[0001] Priority information

[0002] This application claims priority and benefits to patent application No. 202520159084.7, filed with the China National Intellectual Property Administration on January 21, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of heated non-combustible technology, and more specifically, to an aerosol generating device. Background Technology

[0004] Aerosol generating devices are small electronic devices that generate aerosols by heating an aerosol generating matrix in a non-combustible manner. In related technologies, aerosol generating devices often use Hall effect sensors to achieve speed switching. However, Hall effect electronic structures are susceptible to magnetic field failure. Therefore, improving the reliability of speed switching in aerosol generating devices has become a technical problem to be solved. Summary of the Invention

[0005] This application provides an aerosol generating device, which is used to improve the reliability of the aerosol generating device's gear switching.

[0006] The aerosol generating device according to the embodiments of this application includes a circuit board, an operating member, a first conductive member, and a second conductive member. The circuit board includes a first terminal and a second terminal. The operating member is movable relative to the circuit board. The first conductive member is electrically connected to the first terminal. The second conductive member is electrically connected to the first conductive member and is fixedly connected to the operating member. The second conductive member is configured to adjust its electrical connection state with the second terminal as the operating member moves, so as to adjust the working state of the aerosol generating device.

[0007] In the aerosol generating device of this application embodiment, the second conductive element is moved by the operating element to adjust the electrical connection state between the second conductive element and the second terminal, thereby realizing the adjustment of the working state of the aerosol generating device by the change of the position of the conductive contact. This design replaces the Hall effect, has a simple structure, low failure risk, and improves the reliability of the aerosol generating device in switching working states.

[0008] In some embodiments, the operating element and the second conductive element are movable relative to the circuit board to a closed position and an open position. The second terminal includes a closed terminal and a heating terminal. In the closed position, the second conductive element is electrically connected to the closed terminal to adjust the aerosol generating device to a power-off state, and in the open position, it is electrically connected to the heating terminal to adjust the aerosol generating device to a heating preparation state or a heating state.

[0009] In this way, the second conductive element is electrically connected to the closed terminal when it moves to the closed position with the operating element, and electrically connected to the heating terminal when it moves to the open position, thereby improving the reliability of the electronic structure for controlling gear switching.

[0010] In some embodiments, the aerosol generating apparatus further includes a control component for responding to further control commands to control the aerosol generating matrix to switch between a heating state and a heating preparation state when the operating element is in the open position.

[0011] In this way, through the cooperation of the operating components and control components, it is effectively ensured that the aerosol generation matrix is ​​correctly loaded into the heating component before entering the heating state from the heating preparation state, thereby avoiding dry burning.

[0012] In some embodiments, the heating terminal includes a first heating terminal and a second heating terminal, and the open position includes a first position and a second position, wherein the first position is a position between the operating member rotating from the closed position to the second position;

[0013] The second conductive element is used to be electrically connected to the first heating terminal at the first position to cooperate with the control component to adjust the aerosol generating device to a heating preparation state or to adjust the aerosol generating device to a heating state at a first power, and is also used to be electrically connected to the second heating terminal at the second position to cooperate with the control component to adjust the aerosol generating device to a heating preparation state or a heating state at a second power, wherein the first power is less than the second power.

[0014] Thus, when the second conductive element is connected to the first heating terminal at the first position, and the control component switches the aerosol generating device to the heating state, it controls the aerosol generating device to heat with a lower heating power. Conversely, when the control component switches the aerosol generating device to the heating preparation state, the connection of the second conductive element to the first heating terminal controls the aerosol generating device to be in a heating preparation state, preparing to heat with a first power. Similarly, when the second conductive element is connected to the second heating terminal at the second position, and the control component switches the aerosol generating device to the heating state, it controls the aerosol generating device to heat with a higher heating power. Conversely, when the control component switches the aerosol generating device to the heating preparation state, the connection of the second conductive element to the second heating terminal controls the aerosol generating device to be in a heating preparation state, preparing to heat with a second power. This design simplifies the operation of adjusting the heating power and improves reliability.

[0015] In some embodiments, a circuit board is arranged on one side of the operating member, and a first conductive element and a second conductive element are fixedly installed in the operating member. The first conductive element is opposite to and connected to a first terminal. The closing terminal and the heating terminal are distributed at intervals along the moving path of the second conductive element from the closed position to the open position. The second conductive element is opposite to and connected to the heating terminal in the closed position and opposite to and connected to the heating terminal in the open position.

[0016] Thus, by distributing the closing terminal and the heating terminal at intervals along the moving path of the second conductive element from the closed position to the open position, the second conductive element is opposite to and connected to the closing terminal in the closed position, and opposite to and connected to the heating terminal in the open position. As a result, the operating element drives the second conductive element to move, switching the position opposite to the second terminal, thereby stably and reliably controlling the gear switching of the aerosol generating device.

[0017] In some embodiments, the heating terminal includes a first heating terminal and a second heating terminal. The shut-off terminal, the first heating terminal and the second heating terminal are arranged sequentially at intervals on the circuit board, and the connection between the shut-off terminal, the first heating terminal and the second heating terminal coincides with the projection of the movement trajectory of the second conductive element on the circuit board as the operating element moves relative to the circuit board.

[0018] In this way, the distribution of the shut-off terminals and multiple heating terminals matches the movement path of the operating component. When the aerosol generator is in heating mode, the power of the aerosol generator can be adjusted by moving the operating component relative to the circuit board, thereby simplifying the control structure and improving operational convenience. Furthermore, when the aerosol generator is in heating preparation mode, the operating component can be moved to connect to different heating terminals, thus adjusting the initial power of the aerosol generator when switching from heating preparation mode to heating mode.

[0019] In some implementations, the operating element is rotatably configured relative to the circuit board.

[0020] Thus, by rotating the operating component relative to the circuit board, the second conductive component changes its electrical connection with the second terminal. The movement of the operating component is relatively stable, and the change in the electrical connection between the second conductive component and the second terminal is stable and controllable, thereby improving the stability and controllability of the heating preparation state adjustment process of the aerosol generation device.

[0021] In some embodiments, the operating element includes a main body and a toggle part connected to the periphery of the main body. Both the first conductive element and the second conductive element are fixedly connected to the main body. The first conductive element is located at the center of the rotation path of the toggle part, and the second conductive element is spaced apart from the first conductive element.

[0022] Thus, by placing the first conductive element at the center of the rotation path of the toggle part, the first conductive element rotates as the main body rotates and maintains contact with the first terminal. The second conductive element is spaced apart from the first conductive element and rotates around the first conductive element with the main body, changing its contact position with the second terminal.

[0023] In some embodiments, the circuit board is disposed below the main body, the first terminal is directly opposite to and connected to the first conductive element, and the second terminal is distributed with the first terminal as the center and the distance between the second conductive element and the first conductive element as the radius. The second conductive element is configured to switch the position opposite to and connected to the second terminal as the operating element rotates relative to the circuit board.

[0024] In this way, the operating component rotates relative to the circuit board and drives the second conductive component to rotate around the first conductive component, and then sequentially abuts against the second terminals distributed with the first terminal as the center and the distance between the second conductive component and the first conductive component as the radius, thereby stably and reliably controlling the gear switching of the aerosol generating device.

[0025] In some embodiments, the aerosol generating apparatus includes a housing assembly having a relief groove extending along the rotation path of an actuating part, the actuating part extending at least partially through the relief groove outside the housing assembly.

[0026] Thus, by extending the relief groove along the transmission path of the actuating part, the actuating part extends at least partially through the relief groove outside the housing assembly, allowing the user to actuate the operating element from the actuating part outside the relief groove to adjust the gear position, which is convenient to operate, and the relief groove can play a certain limiting role in the movement of the actuating part.

[0043] Please refer to Figure 1. The aerosol generating device 100 is a structure capable of generating aerosols by acting on an aerosol generating matrix (not shown) through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration. The aerosol generating matrix is ​​a plant leaf product that has been treated and heated to produce aerosols. The aerosol generating matrix can be in a fully solid or semi-solid state. When the aerosol generating matrix is ​​fully solid, it can be prepared using processes such as rolling, slurry preparation, die casting, or extrusion. The aerosol generating matrix can be a cylindrical structure similar to a cigarette, or a sheet-like, strip-like, or block-like structure.

[0044] Aerosol generating matrix is ​​atomized by heating to form aerosols. Aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which are typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. Users can inhale aerosols into their mouth, nasal cavity, or lungs through their mouth or nose. Aerosols inhaled into the user's respiratory system can be used for various purposes such as food, medicine, and health care.

[0045] In related technologies, aerosol generating devices use Hall effect sensors to switch between heating modes to meet different heating requirements. However, Hall effect structures are relatively complex and pose a potential risk of magnetic field failure.

[0046] Please refer to Figures 2-4. The aerosol generating device 100 of this application embodiment includes a circuit board 10, an operating member 20, a first conductive member 30, and a second conductive member 40. The circuit board 10 includes a first terminal 11 and a second terminal 12. The operating member 20 is movable relative to the circuit board 10. The first conductive member 30 is electrically connected to the first terminal 11. The second conductive member 40 is electrically connected to the first conductive member 30 and is fixedly connected to the operating member 20. The second conductive member 40 is configured to adjust its electrical connection state with the second terminal 12 as the operating member 20 moves, so as to adjust the working state of the aerosol generating device 100.

[0047] In the aerosol generating device 100 of this application embodiment, the second conductive element 40 is moved by the operating element 20 to adjust the electrical connection state between the second conductive element 40 and the second terminal 12, thereby realizing the adjustment of the working state of the aerosol generating device 100 by the change of the position of the conductive contact. This design replaces the Hall effect, has a simple structure, low failure risk, and improves the reliability of the aerosol generating device 100's gear switching.

[0048] Specifically, the second conductive element 40 is fixedly connected to the operating element 20 and moves synchronously with the operating element 20 to change the relative position of the second conductive element 40 and the circuit board 10, thereby adjusting the connection position of the second conductive element 40 and the second terminal 12.

[0049] Optionally, the first terminal 11 and the second terminal 12 are distributed in a dotted pattern on the circuit board 10.

[0050] Optionally, the first conductive element 30 and the second conductive element 40 are columnar, and one side of the first conductive element 30 and the second conductive element 40 along the axial direction faces the circuit board 10. The first conductive element 30 abuts against the first terminal 11, and the second conductive element 40 abuts against the second terminal 12.

[0051] Optionally, the first conductive element 30 and the first terminal 11, and the second conductive element 40 and the second terminal 12 can form elastic contact.

[0052] For example, the first conductive element 30 has a first ball 31 protruding from its end face facing the circuit board 10, and the second conductive element 40 has a second ball 41 protruding from its end face facing the circuit board 10. The first ball 31 can move relative to the end face of the first conductive element 30 when subjected to force. When the first conductive element 30 abuts against the first terminal 11, the first ball 31 is pressed and moves inward relative to the end face of the first conductive element 30, and protrudes outward relative to the end face of the first conductive element 30 when the first conductive element 30 separates from the first terminal 11, thereby ensuring good contact between the first conductive element 30 and the first terminal 11. Similarly, the second ball 41 is pressed and moves inward relative to the end face of the second conductive element 40 when the second conductive element 40 abuts against the second terminal 12, and protrudes outward relative to the end face of the second conductive element 40 when the second conductive element 40 separates from the second terminal 12, thereby ensuring good contact between the second conductive element 40 and the second terminal 12.

[0053] The circuit board 10 outputs a corresponding electrical signal according to the electrical connection state between the second conductive element 40 and the second terminal 12. The aerosol generating device 100 heats the aerosol generating matrix with the heating power corresponding to the electrical signal output by the circuit board 10, thereby realizing the opening and closing of the aerosol generating device 100 and the switching of the heating level.

[0054] Please refer to Figures 3, 5, and 6. In some embodiments, the operating element 20 and the second conductive element 40 are movable relative to the circuit board 10 to a closed position and an open position. The second terminal 12 includes a closed terminal 121 and a heating terminal 122. In the closed position, the second conductive element 40 is electrically connected to the closed terminal 121 to adjust the aerosol generating device 100 to a power-off state, and in the open position, it is electrically connected to the heating terminal 122 to adjust the aerosol generating device 100 to a heating preparation state or a heating state.

[0055] Thus, when the second conductive element 40 moves to the closed position with the operating element 20, it is electrically connected to the closed terminal 121, and when it moves to the open position, it is electrically connected to the heating terminal 122, thereby improving the reliability of the electronic structure for controlling gear switching.

[0056] Specifically, the aerosol generating device 100 also has a loading hole 504, which connects to the internal and external environments of the aerosol generating device 100 and is used to insert the aerosol generating substrate. When the aerosol generating device 100 is off, the loading hole 504 is closed; when in the heating preparation state, the loading hole 504 is open, allowing the aerosol generating substrate to be inserted for heating and aerosol generation. The second conductive element 40 is fixedly connected to the operating element 20 and moves synchronously with the operating element 20 relative to the circuit board 10. In the closed position, the second conductive element 40 abuts against the closed terminal 121; in the open position, the second conductive element 40 abuts against the heating terminal 122.

[0057] The operating element 20 can move relative to the circuit board 10 in at least one of the following motion forms: rotation, swing, translation, etc. In some embodiments, the operating element 20 can also be an interactive screen, where users can perform virtual operations to adjust the contact mode between the second conductive element 40 and the second terminal 12, thereby adjusting the working state of the aerosol generating device 100.

[0058] For example, the second conductive element 40 is fixedly connected to the operating element 20, and the second terminal 12 is fixedly disposed on the circuit board 10. The second conductive element 40 can rotate, swing, translate, or move relative to the second terminal 12. The relative position of the second conductive element 40 and the second terminal 12 changes the movement trajectory of the operating element 20, so as to realize the change of the electrical connection state between the second conductive element 40 and the second terminal 12.

[0059] In some embodiments, the aerosol generating apparatus 100 further includes a control component (not shown) that is used to control the aerosol generating matrix to switch between a heating state and a heating preparation state when the operating element is in the open position, in response to further control commands.

[0060] In this way, by cooperating with the operating component 20 and the control component, it is effectively ensured that after the aerosol generation matrix is ​​correctly loaded into the heating component, it will enter the heating state from the heating preparation state, thereby avoiding dry burning.

[0061] Specifically, the aerosol generating device 100 includes a heating component (not shown), and the control component and circuit board 10 are both electrically connected to the heating component. The heating component is used to start and heat the aerosol generating matrix in a heating state, and to stop heating in a shutdown state. In a heating preparation state, the aerosol generating device 100 allows the aerosol generating matrix to enter the heating component, and the heating component is in a standby state, ready to start but not heating, in the heating preparation state.

[0062] It should be noted that the further control commands include detecting the cigarette in place, user interaction, etc., wherein the user interaction methods can be further activity of the operating component 20, button, screen control, inhalation status, etc.

[0063] For example, the aerosol generating device 100 may be equipped with a sensor (not shown) or other components to detect whether the aerosol generating matrix in the heating assembly is in place. The control assembly can control the heating assembly to start or stop in response to the detection result. For example, when the operating member 20 moves from the closed position relative to the housing 50 to the open position, it drives the loading hole 504 to open, adjusting the aerosol generating device 100 to the heating preparation state. At this time, the heating assembly is not started. The aerosol generating matrix is ​​inserted into the loading hole 504 and correctly loaded into the heating assembly through the loading hole 504. The control assembly then controls the heating assembly to start.

[0064] During the process of the aerosol generating device 100 transitioning from the heating preparation state to the heating state, and during the heating process of the heating component, the second conductive element 40 can remain connected to the heating terminal 122.

[0065] After the sensing component detects that the aerosol generating matrix has been removed from the loading hole 504, the control component controls the heating component to stop heating, and the operating component 20 can move from the open position to the closed position, adjusting the aerosol generating device 100 to the off state, and the loading hole 504 is closed.

[0066] In some embodiments, the heating terminal 122 includes a first heating terminal 1221 and a second heating terminal 1222. The opening position of the operating member 20 may include a first position (as shown in FIG6) and a second position (as shown in FIG7). The first position is the position between the operating member 20 rotating from the closed position to the second position.

[0067] The second conductive element 40 is used to be electrically connected to the first heating terminal 1221 at a first position to cooperate with the control component to adjust the aerosol generating device 100 to a heating preparation state or to adjust the aerosol generating device 100 to a heating state at a first power, and is also used to be electrically connected to the second heating terminal 1222 at a second position to cooperate with the control component to adjust the aerosol generating device 100 to a heating preparation state or a heating state at a second power, wherein the first power is less than the second power.

[0068] Thus, when the second conductive element 40 is connected to the first heating terminal 1221 at the first position, and the control component switches the aerosol generating device 100 to the heating state, it controls the aerosol generating device 100 to heat with a lower heating power. When the control component switches the aerosol generating device 100 to the heating preparation state, the connection between the second conductive element 40 and the first heating terminal 1221 controls the aerosol generating device 100 to be in a heating preparation state, ready to heat with a first power. Similarly, when the second conductive element 40 is connected to the second heating terminal 1222 at the second position, and the control component switches the aerosol generating device 100 to the heating state, it controls the aerosol generating device 100 to heat with a higher heating power. When the control component switches the aerosol generating device 100 to the heating preparation state, the connection between the second conductive element 40 and the second heating terminal 1222 controls the aerosol generating device 100 to be in a heating preparation state, ready to heat with a second power. This design simplifies the operation of adjusting the heating power and improves reliability.

[0069] Specifically, the second conductive element 40 moves relative to the circuit board 10 with the operating element 20, from the closed position to the first position. The second terminal 12 connected to the second conductive element 40 switches from the closed terminal 121 to the first heating terminal 1221. The control component responds to the user's or the aerosol generating matrix's status command and adjusts the aerosol generating device 100 to the heating preparation state. The second conductive element 40 moves relative to the housing with the operating element 20, rotating from the first position to the second position. The first heating terminal 1221 connected to the second conductive element 40 switches to the second heating terminal 1222. The control component responds to a further command and adjusts the aerosol generating device 100 to the heating state. The heating power of the aerosol generating device 100 can increase from zero to a positive value.

[0070] In other embodiments, the second conductive element 40 moves relative to the housing with the operating element 20, from a closed position to a first position. The second terminal 12 connected to the second conductive element 40 switches from a closed terminal 121 to a first heating terminal 1221. The control component responds to a user's or aerosol generating matrix status command, adjusting the aerosol generating device 100 to a heating preparation state. Subsequently, in response to a further command, the control component adjusts the aerosol generating device 100 to a heating state, with the second conductive element 40 remaining in the first position and correspondingly connected to the first heating terminal 1221, controlling the aerosol generating device 100 to begin heating at a first power.

[0071] Please refer to Figures 5-7. In some embodiments, the heating terminal 122 includes a first heating terminal 1221 and a second heating terminal 1222. The shut-off terminal 121, the first heating terminal 1221 and the second heating terminal 1222 are spaced apart on the circuit board 10. The connection between the shut-off terminal 121, the first heating terminal 1221 and the second heating terminal 1222 can coincide with the projection of the second conductive element 40 on the circuit board 10 on the trajectory of the movement of the operating element 20 relative to the circuit board 10.

[0072] Thus, the distribution positions of the shut-off terminal 121 and the multiple heating terminals 122 are matched with the movement path of the operating member 20. When the aerosol generating device 100 is in the heating state, the power of the aerosol generating device 100 can be adjusted by moving the operating member 20 relative to the circuit board 10, thereby simplifying the control structure and improving operational convenience. In addition, when the aerosol generating device 100 is in the heating preparation state, the operating member 20 can be moved to connect with different heating terminals 122, which can also adjust the initial power of the aerosol generating device 100 when switching from the heating preparation state to the heating state.

[0073] Specifically, the second conductive element 40 is connected to the first heating terminal 1221 at the first position. When the control component adjusts the aerosol generating device 100 to the heating equipment state, the aerosol generating device 100 does not heat. When the control component adjusts the aerosol generating device 100 to the heating state, the heating power of the aerosol generating device 100 is the first power. The second conductive element 40 is connected to the second heating terminal 1222 at the second position. When the control component adjusts the aerosol generating device 100 to the heating equipment state, the aerosol generating device 100 does not heat. When the control component adjusts the aerosol generating device 100 to the heating state, the heating power of the aerosol generating device 100 is the second power.

[0074] In the heating state, the operating member 20 can move from the first position to the second position, or from the second position to the first position, so that the second conductive member 40 is connected to the first heating terminal 1221 or the second heating terminal 1222 respectively, and the aerosol generating device 100 is controlled to heat with the first power or the second power respectively, thereby simply and reliably adjusting the heating power of the aerosol generating device 100 in the heating state.

[0075] The operating element 20 and the second conductive element 40 can also move in the opposite direction to the circuit board 10, changing from the second position or the first position to the first position or the closed position, controlling the aerosol generating device 100 to switch from the heating state to the heating preparation state or the shutdown state accordingly; or the second conductive element 40 moves from the second position to the first position along with the operating element 20, controlling the heating power of the aerosol generating device 100 to decrease from the second power to the first power.

[0076] In other embodiments, the second conductive element 40 is connected to the first heating terminal 1221. The aerosol generating device 100 is adjusted to a heating state as the aerosol generating substrate is positioned in the heating assembly, and heats the aerosol generating substrate with a first power, while the second conductive element 40 remains connected to the first heating terminal 1221. The second conductive element 40 then moves again relative to the circuit board 10 with the operating element 20, switching to a connection with the second heating terminal 1222. The heating power of the aerosol generating device 100 in the heating state is adjusted to a second power, where the first power is less than the second power. This allows for preheating of the aerosol generating substrate, improving the heating effect.

[0077] In some embodiments, the number of heating terminals 122 is three or more. When the aerosol generating device 100 is in the heating state, the aerosol generating device can be adjusted to a corresponding heating power level when the second conductive element 40 is connected to each heating terminal 122. The number of heating power levels corresponds one-to-one with the number of heating terminals 122. When the second conductive element is connected to different heating terminals, the aerosol generating device can be adjusted to heat with different heating power levels.

[0078] Referring to Figures 3-5, in some embodiments, the circuit board 10 is arranged on one side of the operating member 20, and the first conductive member 30 and the second conductive member 40 are fixedly installed in the operating member 20. The first conductive member 30 is opposite to and connected to the first terminal 11. The closing terminal 121 and the heating terminal 122 are distributed at intervals along the moving path of the second conductive member 40 from the closed position to the open position. The second conductive member 40 is opposite to and connected to the closing terminal 121 in the closed position, and opposite to and connected to the heating terminal 122 in the open position.

[0079] Thus, by distributing the closing terminal 121 and the heating terminal 122 at intervals along the moving path of the second conductive member 40 from the closed position to the open position, the second conductive member 40 is opposite to and connected to the closing terminal 121 in the closed position, and opposite to and connected to the heating terminal 122 in the open position. As a result, the operating member 20 drives the second conductive member 40 to move, switching the position opposite to the second terminal 12, thereby stably and reliably controlling the gear switching of the aerosol generating device 100.

[0080] Specifically, the first conductive element 30 and the second conductive element 40 can be embedded in the operating member 20 and partially exposed on the side surface of the operating member 20 facing the circuit board 10. The portions of the first conductive element 30 and the second conductive element 40 exposed on the surface of the operating member 20 are opposite to and connected to the first terminal 11 and the second terminal 12, respectively. The relative position of the first conductive element 30 and the first terminal 11 can be fixed during the movement of the operating member 20 relative to the circuit board 10, and can be kept in contact with the first terminal 11 to maintain an electrical connection between the first conductive element 30 and the first terminal 11.

[0081] Optionally, the second terminal includes a closing terminal 121, a first heating terminal 1221, and a second heating terminal 1222. The open position includes a first position and a second position. The closing terminal 121, the first heating terminal 1221, and the second heating terminal 1222 are distributed at intervals along the movement path of the second conductive member 40 from the closing position to the second position.

[0082] Optionally, the second terminal includes a shut-off terminal 121 and a plurality of heating terminals 122, wherein the number of heating terminals 122 is three or more, and the shut-off terminal 121 and the plurality of heating terminals 122 are distributed at intervals along the movement path of the second conductive member 40 as it switches from the shut-off position to the open position. Further, the shut-off terminal 121 and the plurality of heating terminals 122 may be distributed at equal intervals along the movement path of the second conductive member 40.

[0083] Referring to Figures 3 and 5, in some embodiments, the operating member 20 is rotatably disposed relative to the circuit board 10. Thus, the rotation of the operating member 20 relative to the circuit board 10 causes the second conductive element 40 to change its electrical connection state with the second terminal 12. The movement of the operating member 20 is more stable, and the change in the electrical connection state between the second conductive element 40 and the second terminal 12 is stable and controllable, thereby improving the stability and controllability of the heating preparation state adjustment process of the aerosol generating device 100.

[0084] Specifically, the operating element 20 is flat and rotates relative to the circuit board 10 around its rotation center. The rotation center of the operating element 20 can be located at or near its geometric center. The operating element 20 can rotate relative to the circuit board 10 in a clockwise or counterclockwise direction.

[0085] Please refer to Figures 3 and 5. In some embodiments, the operating member 20 includes a main body 21 and a toggle part 22 connected to the periphery of the main body 21. The first conductive member 30 and the second conductive member 40 are both fixedly connected to the main body 21. The first conductive member 30 is located at the center of the rotation path of the toggle part 22, and the second conductive member 40 is spaced apart from the first conductive member 30.

[0086] Thus, by placing the first conductive element 30 at the center of the rotation path of the toggle part 22, the first conductive element 30 rotates as the main body 21 rotates and maintains contact with the first terminal 11. The second conductive element 40 is spaced apart from the first conductive element 30 and rotates around the first conductive element 30 with the main body 21, changing the contact position with the second terminal 12.

[0087] Specifically, the main body 21 can be generally disc-shaped or flattened cylindrical. The actuating part 22 protrudes from the peripheral surface of the main body 21. Under external force, the actuating part 22 can rotate relative to the circuit board 10 around the main body 21, causing the main body 21 to rotate. The rotation path of the actuating part 22 is arc-shaped, and the center of the rotation path is also the rotation center of the entire operating member 20, approximately located at the geometric center of the main body 21. The first conductive member 30 is located at the rotation center of the operating member 20. Its relative position to the circuit board 10 remains unchanged during the rotation of the operating member 20 relative to the circuit board 10, and it is always connected to the first terminal 11. The second conductive member 40 rotates around the first conductive member 30 with the actuating part 22. The distance between the second conductive member 40 and the first conductive member 30 is also the rotation radius of the second conductive member 40.

[0088] Please refer to Figures 3-5. In some embodiments, the circuit board 10 is disposed below the main body 21. The first terminal 11 is directly opposite to and connected to the first conductive member 30. The second terminal 12 is distributed with the first terminal 11 as the center and the distance between the second conductive member 40 and the first conductive member 30 as the radius. The second conductive member 40 is configured to switch the position opposite to and connected to the second terminal 12 as the operating member 20 rotates relative to the circuit board 10.

[0089] In this way, the operating member 20 rotates relative to the circuit board 10 and drives the second conductive member 40 to rotate around the first conductive member 30, and sequentially abuts against the second terminals 12 distributed with the first terminal 11 as the center and the distance between the second conductive member 40 and the second conductive member 40 as the radius, thereby stably and reliably controlling the gear switching of the aerosol generating device 100.

[0090] Specifically, the first terminal 11 is directly opposite the first conductive element 30, which is located at the center of the rotation path of the actuating part 22. The first terminal 11 is also located at the rotation center of the actuating part 22. The second conductive element 40 rotates synchronously with the operating part. The actuating part 22 is located on the outer peripheral surface of the main body 21, and the second conductive element 40 is located between the center and the outer peripheral surface of the main body 21. The rotation path of the second conductive element 40 and the rotation path of the actuating part 22 are two concentric arcs. There are at least two second terminals 12, and several second terminals 12 are distributed with the first terminal 11 as the center and the distance between the second conductive elements 40 and the second conductive element 40 as the radius. The projection of the rotation path of the second conductive element 40 on the circuit board 10 along the direction opposite to the second conductive element 40 and the second terminal 12 coincides with the line connecting the several second terminals 12.

[0091] In one specific embodiment, along one rotation direction of the second conductive member 40, the shut-off terminal 121, the first heating terminal 1221, and the second heating terminal 1222 of the second terminal 12 are sequentially distributed. That is, the line connecting the shut-off terminal 121, the first heating terminal 1221, and the second heating terminal 1222 is an arc with the first terminal 11 as the center. This arc is also the distribution path of the second terminal 12. The second conductive member 40 rotates around the first conductive member 30 above the shut-off terminal 121, the first heating terminal 1221, and the second heating terminal 1222 along the distribution path of the second terminal 12 to change the electrical connection state between the second conductive member 40 and the second terminal 12, thereby adjusting the heating power of the aerosol generating device 100.

[0092] For example, the process of the second conductive element 40 rotating from above the closing terminal 121 to above the first heating terminal 1221 completes the transition from the closed position to the first position. This process controls the aerosol generating device 100 to switch from the off state to the heating preparation state, preparing to start heating after the aerosol generating matrix is ​​in place. Further, the process of the second conductive element 40 rotating from above the first heating terminal 1221 to above the second heating terminal 1222 completes the transition from the first position to the second position. This process can control the aerosol generating device 100 to switch from the heating preparation state to the heating state, heating the aerosol generating matrix.

[0093] For example, the process of the second conductive element 40 rotating from above the closing terminal 121 to above the first heating terminal 1221 completes the transition from the closed position to the first position. This process controls the aerosol generating device 100 to switch from the off state to the heating preparation state. After the aerosol generating matrix is ​​in place, the control component controls the aerosol generating device 100 to switch from the heating preparation state to the heating state and heats at the first power. Further, the second conductive element 40 rotates from above the first heating terminal 1221 to above the second heating terminal 1222, controlling the heating power of the aerosol generating device 100 in the heating state to increase from the first power to the second power. The aerosol generating device 100 remains in the heating state, and the operating element switches between the first position and the second position, controlling the aerosol generating device 100 to heat at the first power or the second power accordingly.

[0094] In some embodiments, the number of heating terminals 122 is three or more, and the shut-off terminal 121 and the three or more heating terminals 122 are sequentially distributed along an arc path with the first terminal 11 as the center and the distance between the second conductive element 40 and the first conductive element 30 as the radius.

[0095] Referring to Figures 1 and 3, in some embodiments, the aerosol generating device 100 includes a housing assembly 50, which has a relief groove 501 extending along the rotation path of the actuating part 22, which extends at least partially through the relief groove 501 outside the housing assembly 50.

[0096] Thus, by extending the relief groove 501 along the transmission path of the actuating part 22, the actuating part 22 extends at least partially through the relief groove 501 outside the housing assembly 50, so that the user can move the operating member 20 from the actuating part 22 outside the relief groove 501 to adjust the gear position, which is convenient to operate, and the relief groove 501 can play a certain limiting role in the movement of the actuating part 22.

[0097] Specifically, the housing assembly 50 includes a bracket 52 and a housing 53. The housing 53 encloses the internal chamber of the aerosol generating device 100. The bracket 52 is disposed inside the housing 53, and the circuit board 10 and the operating element 20 can be mounted on the bracket 52. A relief groove 501 is formed on the housing 53 and is located on one side of the operating element 20. A toggle part 22 can extend from the relief groove 501 so that the user can toggle the operating element 20 to adjust the heating power of the aerosol generating device 100.

[0098] Optionally, as shown in Figure 2, a guide block 521 is provided on the bracket 52, and a guide groove 23 is formed on the operating member 20. The guide groove 23 extends along the rotation direction of the operating member 20, and the guide block 521 abuts against the wall of the guide groove 23 and slides along the wall of the guide groove 23 during the rotation of the operating member 20 relative to the circuit board 10. In other examples, the guide groove 23 may also be formed on the bracket 52, and a wire block is provided on the operating member 20 and cooperates with the guide groove 23 to guide the operating member 20 to rotate in the designed direction.

[0099] In some embodiments, the operating element 20 is conductive, and both the first conductive element 30 and the second conductive element 40 are connected to the operating element 20. Thus, the first conductive element 30 and the second conductive element 40 are electrically connected through the operating element 20, resulting in a more stable electrical connection and a more compact structure.

[0100] Specifically, the operating member 20 includes a disc-shaped main body 21 and a toggle part 22 connected to the periphery of the main body 21. A first conductive member 30 and a second conductive member 40 can be embedded in the main body 21, and the main body 21 is conductive, thereby electrically connecting the first conductive member 30 and the second conductive member 40. Optionally, an insulating protective layer can be provided on the outer surface of the operating member 20.
