[0001] The present application relates to the technical field of heat-not-burn, and more particularly, to an aerosol generating device. BACKGROUND

[0002] The aerosol generating device is a kind of small electronic equipment that heats an aerosol generating substrate by a heat-not-burn method to generate an aerosol. In the related art, the aerosol generating device often uses a Hall to realize gear switching, but the electronic structure in the form of Hall has the risk of magnetic field failure, and therefore, improving the reliability of gear switching of the aerosol generating device becomes a technical problem to be solved. CONTENT OF THE UTILITY MODEL

[0003] The aerosol generating device provided by the embodiments of the present application is at least used to improve the reliability of gear switching of the aerosol generating device.

[0004] The aerosol generating device provided by the embodiments of the present 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 an electrical connection state with the second terminal along with the movement of the operating member to adjust a working state of the aerosol generating device.

[0005] In the aerosol generating device provided by the embodiments of the present application, the second conductive member is moved by the operating member to adjust the electrical connection state between the second conductive member and the second terminal, so that the position change of the conductive contact is used to adjust the working state of the aerosol generating device. This design replaces the Hall form, has a simple structure, has a small risk of failure, and improves the reliability of the aerosol generating device in switching the working state.

[0006] In some embodiments, the operating member and the second conductive member 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. The second conductive member is electrically connected to the closed terminal in the closed position to adjust the aerosol generating device to an off state, and is electrically connected to the heating terminal in the open position to adjust the aerosol generating device to a heating preparation state or a heating state.

[0007] In this way, the second conductive member is electrically connected to the closed terminal when moving to the closed position with the operating member, and is electrically connected to the heating terminal when moving to the open position with the operating member, thereby improving the reliability of the electronic structure for controlling gear switching.

[0008] In some embodiments, the aerosol-generating device further comprises a control assembly for switching the aerosol-generating substrate between the heating state and the heating preparation state in response to a further control instruction when the operating member is in the open position.

[0009] In this way, by the cooperation of the operating member and the control assembly, it is effectively ensured that the aerosol-generating substrate is switched from the heating preparation state to the heating state after being correctly loaded into the heating assembly, thereby avoiding dry burning.

[0010] In some embodiments, the heating terminal comprises a first heating terminal and a second heating terminal, and the open position comprises a first position and a second position, the first position being a position between the operating member being turned from the closed position to the second position;

[0011] The second conductive member is configured to be electrically connected to the first heating terminal in the first position to cooperate with the control assembly to adjust the aerosol-generating device to the heating preparation state or to the heating state at the first power, and to be electrically connected to the second heating terminal in the second position to cooperate with the control assembly to adjust the aerosol-generating device to the heating preparation state or to the heating state at the second power, the first power being less than the second power.

[0012] In this way, the second conductive member is correspondingly connected to the first heating terminal in the first position, and when the control assembly controls the aerosol-generating device to switch to the heating state, the control assembly controls the aerosol-generating device to heat at a lower heating power, and when the control assembly controls the aerosol-generating device to switch to the heating preparation state, the connection of the second conductive member to the first heating terminal controls the aerosol-generating device to the heating preparation state for preparing to heat at the first power. Similarly, the second conductive member is correspondingly connected to the second heating terminal in the second position, and when the control assembly controls the aerosol-generating device to switch to the heating state, the control assembly controls the aerosol-generating device to heat at a higher heating power, and when the control assembly controls the aerosol-generating device to switch to the heating preparation state, the connection of the second conductive member to the second heating terminal controls the aerosol-generating device to the heating preparation state for preparing to heat at the second power. This design simplifies the operation of adjusting the heating power and improves the reliability.

[0013] In some embodiments, the circuit board is arranged on one side of the operating member, the first conductive member and the second conductive member are fixedly installed in the operating member, the first conductive member is opposite to and connected to the first terminal, the closed terminal and the heating terminal are spaced apart along a movement path of the second conductive member from the closed position to the open position, and the second conductive member 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.

[0014] Thus, the second conductive member is opposite to the closing terminal in the closing position and is connected to the closing terminal, and is opposite to the heating terminal in the opening position and is connected to the heating terminal, so that the operation member drives the second conductive member to move and switch the position opposite to the second terminal, thereby stably and reliably controlling the gear switching of the aerosol generating device.

[0015] In some embodiments, the heating terminals include a first heating terminal and a second heating terminal, the closing terminal, the first heating terminal and the second heating terminal are sequentially and spacedly arranged on the circuit board, and the connection lines of the closing terminal, the first heating terminal and the second heating terminal coincide with the projection of the movement track of the second conductive member on the circuit board.

[0016] Thus, the distributed positions of the closing terminal and the plurality of heating terminals match the movement path of the operation member, and when the aerosol generating device is in the heating state, the power of the aerosol generating device is adjusted by moving the operation member relative to the circuit board, thereby simplifying the control structure and improving the operation convenience. In addition, when the aerosol generating device is in the heating preparation state, the operation member is moved to be connected to different heating terminals, and the initial power of the aerosol generating device when switching from the heating preparation state to the heating state can also be adjusted.

[0017] In some embodiments, the operation member is rotationally arranged relative to the circuit board.

[0018] Thus, the operation member is rotationally arranged relative to the circuit board.

[0019] In some embodiments, the operation member includes a main body portion and a knob portion connected to the side of the main body portion, the first conductive member and the second conductive member are fixedly connected to the main body portion, the first conductive member is located at the center of the rotation path of the knob portion, and the second conductive member is spacedly arranged relative to the first conductive member.

[0020] Thus, by arranging the first conductive member at the center of the rotation path of the knob portion, the first conductive member rotates around the first terminal during the rotation of the main body portion, and the second conductive member is spacedly arranged relative to the first conductive member and rotates around the first conductive member, thereby changing the contact position with the second terminal.

[0021] In some embodiments, the circuit board is arranged below the main body, the first terminal is opposite and connected with the first conductive member, the second terminal is distributed with the first terminal as the center and the second conductive member and the interval between the second conductive members as the radius, and the second conductive member is configured to switch the position opposite and connected with the second terminal as the operating member rotates relative to the circuit board.

[0022] In this way, the operating member rotates relative to the circuit board and drives the second conductive member to rotate around the first conductive member, and in turn abuts against the second terminal distributed with the first terminal as the center and the second conductive member and the interval between the second conductive members as the radius, thereby stably and reliably controlling the gear switching of the aerosol generating device.

[0023] In some embodiments, the aerosol generating device comprises a housing assembly, the housing assembly is formed with a clearance slot, the clearance slot extends along the rotation path of the actuating part, and the actuating part at least partially extends outside the housing assembly through the clearance slot.

[0024] In this way, by extending the clearance slot along the transmission path of the actuating part, the actuating part at least partially extends outside the housing assembly through the clearance slot, so that the user can actuate the operating member to adjust the gear from the actuating part outside the clearance slot, which is convenient to operate, and the clearance slot can limit the movement of the actuating part.

[0041] Please refer to Figure 1 , the aerosol generating device 100 is a structure capable of generating aerosol by acting on an aerosol generating substrate (not shown) through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasonic or mechanical oscillation. The aerosol generating substrate is a plant leaf product that has been processed and can generate aerosol after being heated. The aerosol generating substrate can be in a full solid state or a semi-solid state. In the case of a full solid state, the aerosol generating substrate can be prepared by processes such as rolling, thick paste, die casting, and extrusion. The aerosol generating substrate can be a cylindrical structure similar to a cigarette, or a sheet structure, a strip structure, or a block structure.

[0042] 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.

[0043] 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.

[0044] Please see Figures 2-4 The aerosol generating device 100 of this application 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.

[0045] 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.

[0046] 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.

[0047] Optionally, the first terminal 11 and the second terminal 12 are distributed in a dotted pattern on the circuit board 10.

[0048] 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.

[0049] 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.

[0050] For example, the first conductive member 30 is provided with a first ball 31 protruding from the end surface of the circuit board 10 toward the end surface of the circuit board 10, and the second conductive member 40 is provided with a second ball 41 protruding from the end surface of the circuit board 10 toward the end surface of the circuit board 10. The first ball 31 is movable relative to the end surface of the first conductive member 30 when subjected to a force, and the first ball 31 moves inward of the first conductive member 30 relative to the end surface of the first conductive member 30 when the first conductive member 30 is pressed against the first terminal 11, and the first ball 31 protrudes outward relative to the end surface of the first conductive member 30 when the first conductive member 30 is separated from the first terminal 11, thereby ensuring good contact between the first conductive member 30 and the first terminal 11. Similarly, the second ball 41 moves inward of the second conductive member 40 relative to the end surface of the second conductive member 40 when the second conductive member 40 is pressed against the second terminal 12, and the second ball 41 protrudes outward relative to the end surface of the second conductive member 40 when the second conductive member 40 is separated from the second terminal 12, thereby ensuring good contact between the second conductive member 40 and the second terminal 12.

[0051] The circuit board 10 outputs an electrical signal corresponding to the electrical connection state between the second conductive member 40 and the second terminal 12, and the aerosol generating device 100 heats the aerosol generating substrate at a heating power corresponding to the electrical signal output by the circuit board 10, thereby switching the on / off and the heating level of the aerosol generating device 100.

[0052] Referring to Figure 3 , Figure 5 and Figure 6 In some embodiments, the operation member 20 and the second conductive member 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, and the second conductive member 40 is electrically connected to the closed terminal 121 in the closed position to adjust the aerosol generating device 100 to an off state, and is electrically connected to the heating terminal 122 in the open position to adjust the aerosol generating device 100 to a heating preparation state or a heating state.

[0053] In this way, the second conductive member 40 is electrically connected to the closed terminal 121 when the operation member 20 is moved to the closed position, and is electrically connected to the heating terminal 122 when the operation member 20 is moved to the open position, thereby improving the reliability of the electronic structure for controlling the switching of the levels.

[0054] Specifically, the aerosol-generating device 100 is further formed with a loading hole 504, which communicates the inside and outside of the aerosol-generating device 100 and is used for inserting the aerosol-generating substrate. The loading hole 504 is closed in the off state of the aerosol-generating device 100, and is opened in the heating preparation state, so that the aerosol-generating substrate can be inserted from the loading hole 504 and be prepared for heating and generating aerosol. The second conductive member 40 is fixedly connected with the operating member 20 and moves synchronously relative to the circuit board 10. In the closed position, the second conductive member 40 abuts against the closing terminal 121, and in the open position, the second conductive member 40 abuts against the heating terminal 122.

[0055] The operating member 20 can move in at least one of the forms of rotation, oscillation, translation, etc. relative to the circuit board 10. In other embodiments, the operating member 20 can also be an interactive screen, and the user can perform virtual operations on the operating member 20 to adjust the abutting mode of the second conductive member 40 on the operating member 20 with the second terminal 12, thereby achieving adjustment of the working state of the aerosol-generating device 100.

[0056] For example, the second conductive member 40 is fixedly connected with the operating member 20, and the second terminal 12 is fixedly arranged on the circuit board 10. The second conductive member 40 can move in at least one of the forms of rotation, oscillation, translation, etc. relative to the second terminal 12. The relative position of the second conductive member 40 and the second terminal 12 changes with the movement trajectory of the operating member 20, so as to change the electrical connection state of the second conductive member 40 and the second terminal 12.

[0057] In some embodiments, the aerosol-generating device further comprises a control assembly (not shown in the figure) for controlling the aerosol-generating substrate to switch between the heating state and the heating preparation state in response to a further control instruction when the operating member is in the open position.

[0058] In this way, through the cooperation of the operating member 20 and the control assembly, it is effectively ensured that the aerosol-generating substrate is correctly loaded into the heating assembly before entering the heating state from the heating preparation state, thereby avoiding dry burning.

[0059] Specifically, the aerosol-generating device 100 comprises a heating assembly (not shown in the figure), and the control assembly and the circuit board 10 are electrically connected with the heating assembly. The heating assembly is used for starting and heating the aerosol-generating substrate in the heating state, and is used for stopping heating in the off state. The aerosol-generating device 100 allows the aerosol-generating substrate to enter the heating assembly in the heating preparation state, and the heating assembly is in a standby state of being started but not heated in the heating preparation state.

[0060] It should be noted that the further control instructions include detection of a cigarette in place, user interaction, etc., wherein the user interaction can be further movement of the operating member 20, a button, screen control, puffing state, etc.

[0061] For example, the aerosol generating device 100 can be provided with a sensor (not shown in the figure) or the like to detect whether the aerosol generating substrate in the heating assembly is in place, and the control assembly can control the heating assembly to start or stop in response to the detection result. For example, the operating member 20 is moved from the closed position to the open position relative to the housing 50, driving the loading hole 504 to open, adjusting the aerosol generating device 100 to a heating preparation state, at which time the heating assembly is not started; the aerosol generating substrate is inserted into the loading hole 504 and correctly loaded into the heating assembly through the loading hole 504, and the control assembly controls the heating assembly to start.

[0062] During the process of the aerosol generating device 100 from the heating preparation state to the heating state and the heating assembly heating, the second conductive member 40 can remain connected to the heating terminal 122.

[0063] After the induction assembly senses that the aerosol generating substrate is withdrawn from the loading hole 504, the control assembly controls the heating assembly to stop heating, and the operating member 20 can be moved from the open position to the closed position, adjusting the aerosol generating device 100 to an off state, and the loading hole 504 is closed.

[0064] In some embodiments, the heating terminal 122 includes a first heating terminal 1221 and a second heating terminal 1222, and the open position of the operating member 20 can include a first position (as shown in Figure 6 ) and a second position (as shown in Figure 7 ), the first position being a position between the closed position and the second position of the operating member 20;

[0065] The second conductive member 40 is used to electrically connect the first heating terminal 1221 in the first position, so as to cooperate with the control assembly to adjust the aerosol generating device 100 to the heating preparation state or the heating state at the first power, and to electrically connect the second heating terminal 1222 in the second position, so as to cooperate with the control assembly to adjust the aerosol generating device 100 to the heating preparation state or the heating state at the second power, the first power being less than the second power.

[0066] Thus, the second conductive member 40 is connected to the first heating terminal 1221 in the first position, and when the control assembly controls the aerosol generating device 100 to switch to the heating state, the aerosol generating device 100 is controlled to heat at a lower heating power. When the control assembly controls the aerosol generating device 100 to switch to the heating preparation state, the second conductive member 40 is connected to the first heating terminal 1221, which controls the aerosol generating device 100 to be in the heating preparation state in preparation for heating at the first power. Similarly, the second conductive member 40 is connected to the second heating terminal 1222 in the second position, and when the control assembly controls the aerosol generating device 100 to switch to the heating state, the aerosol generating device 100 is controlled to heat at a higher heating power. When the control assembly controls the aerosol generating device 100 to switch to the heating preparation state, the second conductive member 40 is connected to the second heating terminal 1222, which controls the aerosol generating device 100 to be in the heating preparation state in preparation for heating at the second power. This design simplifies the operation of adjusting the heating power and improves reliability.

[0067] Specifically, the second conductive member 40 moves with the operation member 20 relative to the circuit board 10 from the closed position to the first position, and the second terminal 12 connected to the second conductive member 40 switches from the closed terminal 121 to the first heating terminal 1221. The control assembly adjusts the aerosol generating device 100 to be in the heating preparation state in response to a state instruction of the user or the aerosol generating substrate. The second conductive member 40 moves with the operation member 20 relative to the housing from the first position to the second position, and the second terminal 12 connected to the second conductive member 40 switches from the first heating terminal 1221 to the second heating terminal 1222. The control assembly adjusts the aerosol generating device 100 to be in the heating state in response to a further instruction, and the heating power of the aerosol generating device 100 can increase from zero to a positive value.

[0068] In other embodiments, the second conductive member 40 moves with the operation member 20 relative to the housing from the closed position to the first position, and the second terminal 12 connected to the second conductive member 40 switches from the closed terminal 121 to the first heating terminal 1221. The control assembly adjusts the aerosol generating device 100 to be in the heating preparation state in response to a state instruction of the user or the aerosol generating substrate. Then, the control assembly adjusts the aerosol generating device 100 to be in the heating state in response to a further instruction, and the second conductive member 40 remains in the first position connected to the first heating terminal 1221, which controls the aerosol generating device 100 to start heating at the first power.

[0069] Please refer to Figures 5-7In some embodiments, the heating terminals 122 include 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 arranged at intervals on the circuit board 10, and the connection lines of 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 member 40 on the circuit board 10 along the movement trajectory of the operating member 20 relative to the circuit board 10.

[0070] In this way, the distributed positions of the shut-off terminal 121 and the plurality of heating terminals 122 match the movement path of the operating member 20, and when the aerosol generating device 100 is in the heating state, the power of the aerosol generating device 100 is adjusted by the movement of the operating member 20 relative to the circuit board 10, thereby simplifying the control structure and improving the operation convenience. In addition, when the aerosol generating device 100 is in the heating preparation state, the operating member 20 is moved to connect with different heating terminals 122, and the initial power of the aerosol generating device 100 when switching from the heating preparation state to the heating state can also be adjusted.

[0071] Specifically, the second conductive member 40 is connected to the first heating terminal 1221 at the first position, and when the control assembly adjusts the aerosol generating device 100 to be in the heating preparation state, the aerosol generating device 100 does not perform heating, and when the control assembly adjusts the aerosol generating device 100 to be in the heating state, the heating power of the aerosol generating device 100 is the first power. The second conductive member 40 is connected to the second heating terminal 1222 at the second position, and when the control assembly adjusts the aerosol generating device 100 to be in the heating preparation state, the aerosol generating device 100 does not perform heating, and when the control assembly adjusts the aerosol generating device 100 to be in the heating state, the heating power of the aerosol generating device 100 is the second power.

[0072] In the heating state, the operating member 20 can be moved 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 perform heating at 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.

[0073] The operating member 20 and the second conductive member 40 can also move reversely relative to the circuit board 10, and transition from the second position or the first position to the first position or the off position, thereby controlling the aerosol generating device 100 to correspondingly switch from the heating state to the heating preparation state or the off state; or the second conductive member 40 moves with the operating member 20 from the second position to the first position, thereby controlling the heating power of the aerosol generating device 100 to decrease from the second power to the first power.

[0074] In some embodiments, the second conductive member 40 is connected with the first heating terminal 1221, the aerosol generating device 100 is adjusted to the heating state when the aerosol generating substrate is in place in the heating assembly, and the aerosol generating substrate is heated at a first power, and the second conductive member 40 remains connected with the first heating terminal 1221. The second conductive member 40 is again moved with the operation member 20 relative to the circuit board 10, switched to be connected 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, and the first power is less than the second power. In this way, the aerosol generating substrate can be preheated to improve the heating effect.

[0075] In some embodiments, the number of heating terminals 122 is three or more, and when the second conductive member 40 is connected with each heating terminal 122, the aerosol generating device 100 in the heating state can be adjusted to a corresponding gear of heating power. The number of gears of heating power corresponds to the number of heating terminals 122, and the second conductive member is connected with different heating terminals, which corresponds to adjusting the aerosol generating device to heat at different heating powers.

[0076] Referring to Figures 3-5 In some embodiments, the circuit board 10 is arranged on one side of the operation member 20, the first conductive member 30 and the second conductive member 40 are fixedly installed in the operation member 20, the first conductive member 30 is opposite to and connected with the first terminal 11, the shut-off terminals 121 and the heating terminals 122 are spaced apart along the movement path of the second conductive member 40 from the closed position to the open position, and the second conductive member 40 is opposite to and connected with the shut-off terminals 121 in the closed position, and is opposite to and connected with the heating terminals 122 in the open position.

[0077] In this way, by spacing the shut-off terminals 121 and the heating terminals 122 along the movement 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 with the shut-off terminals 121 in the closed position, and is opposite to and connected with the heating terminals 122 in the open position, so that the operation member 20 drives the second conductive member 40 to move, switches the position opposite to the second terminal 12, and stably and reliably controls the gear switching of the aerosol generating device 100.

[0078] Specifically, the first conductive member 30 and the second conductive member 40 can be embedded in the operation member 20 and partially exposed on the side surface of the operation member 20 facing the circuit board 10. The portions of the first conductive member 30 and the second conductive member 40 exposed on the surface of the operation member 20 are opposite to and connected with the first terminal 11 and the second terminal 12, respectively. The relative position of the first conductive member 30 to the first terminal 11 during the movement of the operation member 20 relative to the circuit board 10 can remain fixed, and the first conductive member 30 can remain in abutment with the first terminal 11 to maintain electrical connection between the first conductive member 30 and the first terminal 11.

[0079] Optionally, the second terminal comprises a closing terminal 121, a first heating terminal 1221 and a second heating terminal 1222, the opening position comprises a first position and a second position, the closing terminal 121, the first heating terminal 1221 and the second heating terminal 1222 are arranged along the moving path of the second conductive member 40 from the closing position to the second position in sequence.

[0080] Optionally, the second terminal comprises a closing terminal 121 and a plurality of heating terminals 122, the number of the heating terminals 122 is three or more, the closing terminal 121 and the plurality of heating terminals 122 are arranged along the moving path of the second conductive member 40 from the closing position to the opening position in sequence. Further, the closing terminal 121 and the plurality of heating terminals 122 can be arranged at equal intervals along the moving path of the second conductive member 40.

[0081] Please refer to Figure 3 and Figure 5 In some embodiments, the operating member 20 is arranged to rotate relative to the circuit board 10. In this way, the second conductive member 40 changes the electrical connection state with the second terminal 12 through the rotation of the operating member 20 relative to the circuit board 10, the movement of the operating member 20 is relatively stable, and the change of the electrical connection state of the second conductive member 40 with 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.

[0082] Specifically, the operating member 20 is in the shape of a flat body and rotates relative to the circuit board 10 around a rotation center, which can be located at or close to the geometric center of the operating member 20. The operating member 20 can rotate relative to the circuit board 10 in the clockwise direction or the counterclockwise direction.

[0083] Please refer to Figure 3 and Figure 5 In some embodiments, the operating member 20 comprises a main body part 21 and a knob part 22 connected to the side of the main body part 21, the first conductive member 30 and the second conductive member 40 are fixedly connected with the main body part 21, the first conductive member 30 is located at the center of the rotation path of the knob part 22, and the second conductive member 40 is arranged at intervals with the first conductive member 30.

[0084] In this way, by arranging the first conductive member 30 at the center of the rotation path of the knob part 22, the first conductive member 30 rotates around the first terminal 11 during the rotation of the main body part 21, and the second conductive member 40 is arranged at intervals with the first conductive member 30 and rotates around the first conductive member 30, thereby changing the contact position with the second terminal 12.

[0085] Specifically, the main body 21 can be substantially disc-shaped or flat cylindrical. The knob 22 protrudes from the peripheral surface of the main body 21, and the knob 22 can rotate relative to the circuit board 10 about the main body 21 under the action of an external force, and drive the main body 21 to rotate. The rotation path of the knob 22 is a circular arc, and the center of the rotation path of the knob 22, that is, the rotation center of the operating member 20 as a whole, is substantially 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, and the relative position between the first conductive member 30 and the circuit board 10 remains unchanged during the rotation of the operating member 20 relative to the circuit board 10, and the first conductive member 30 is always connected with the first terminal 11. The second conductive member 40 rotates around the first conductive member 30 with the knob 22, and the distance between the second conductive member 40 and the first conductive member 30, that is, the radius of rotation of the second conductive member 40.

[0086] Referring to Figures 3-5 In some embodiments, the circuit board 10 is arranged below the main body 21, the first terminal 11 is opposite to and connected with the first conductive member 30, and 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, and the second conductive member 40 is configured to switch the position opposite to and connected with the second terminal 12 as the operating member 20 rotates relative to the circuit board 10.

[0087] 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 in turn abuts against the second terminal 12 distributed with the first terminal 11 as the center and the second conductive member 40 and the distance between the second conductive member 40 as the radius, thereby stably and reliably controlling the gear switching of the aerosol generating device 100.

[0088] Specifically, the first terminal 11 is opposite to the first conductive member 30, and the first conductive member 30 is located at the center of the rotation path of the knob 22, and the first terminal 11 is also located at the rotation center of the knob 22. The second conductive member 40 rotates synchronously with the operating part, the knob 22 is located on the outer peripheral surface of the main body 21, the second conductive member 40 is located between the center and the outer peripheral surface of the main body 21, and the rotation path of the second conductive member 40 and the rotation path of the knob 22 are two concentric circular arcs. The number of the second terminals 12 is at least two, and a plurality of second terminals 12 are 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, and the projection of the rotation path of the second conductive member 40 on the circuit board 10 in the direction opposite to the second terminal 12 coincides with the line connecting the plurality of second terminals 12.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] Please see Figure 1 and Figure 3In some embodiments, the aerosol-generating device 100 comprises a housing assembly 50 formed with a clearance slot 501 extending along a rotation path of the knob 22, the knob 22 extending at least partially through the clearance slot 501 out of the housing assembly 50.

[0094] In this way, by extending the clearance slot 501 along the transmission path of the knob 22, the knob 22 extends at least partially through the clearance slot 501 out of the housing assembly 50, so that the user can operate the operating member 20 from the knob 22 outside the clearance slot 501 to adjust the gear, which is convenient, and the clearance slot 501 can limit the movement of the knob 22 to a certain extent.

[0095] Specifically, the housing assembly 50 comprises a bracket 52 and a shell 53, the shell 53 enclosing an internal chamber of the aerosol-generating device 100, and the bracket 52 is arranged inside the shell 53, and the circuit board 10 and the operating member 20 can be mounted on the bracket 52. The clearance slot 501 is formed on the shell 53 and located on one side of the operating member 20. The knob 22 can extend from the clearance slot 501 so that the user can operate the operating member 20 to adjust the heating power of the aerosol-generating device 100.

[0096] Alternatively, as shown in Figure 2 The bracket 52 is provided with a guide block 521, and the operating member 20 is formed with a guide groove 23 extending in the rotation direction of the operating member 20, the guide block 521 abutting against the wall surface of the guide groove 23 and sliding along the wall surface 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 can also be formed on the bracket 52, and the guide block is arranged on the operating member 20 and cooperates with the guide groove 23 to guide the rotation of the operating member 20 in the designed direction.

[0097] In some embodiments, the operating member 20 is conductive, and the first conductive member 30 and the second conductive member 40 are connected to the operating member 20. In this way, the first conductive member 30 and the second conductive member 40 are electrically connected through the operating member 20, so that the electrical connection is more stable and the structure is more compact.

[0098] Specifically, the operating member 20 comprises a main body 21 in the shape of a disc and a knob 22 connected to the side of the main body 21, and the first conductive member 30 and the second conductive member 40 can be embedded in the main body 21, and the main body 21 is conductive to electrically connect the first conductive member 30 and the second conductive member 40. Alternatively, an insulating protective layer can be provided on the outer surface of the operating member 20.
