[0027] This utility model proposes an aerosol generating device 100.

[0028] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the aerosol generating device 100 includes a rotary switch structure, a main board 6, and a sensor 3. The rotary switch structure includes a switch base 1 and a knob assembly 2. The switch base 1 has a suction nozzle 11. The knob assembly 2 includes a rotating member 21 and a cover plate 22. Both the rotating member 21 and the cover plate 22 are rotatably mounted on the switch base 1, and the rotating member 21 and the cover plate 22 are connected in a transmission manner. The main board 6 is located on the side of the switch base 1 facing away from the rotating member 21. The sensor 3 includes a sensing element... The aerosol generating device 100 comprises a sensing unit 31 and a sensing unit 32. The sensing unit 32 is used to detect the sensing unit 31. The sensing unit 31 is disposed on the rotating member 21, and the sensing unit 32 is disposed on the main board 6 and electrically connected to the main board 6. The aerosol generating device 100 has a working state and a power-off state. In the working state, the sensing unit 32 is aligned with the sensing unit 31, and the cover plate 22 opens the suction nozzle 11. In the power-off state, the sensing unit 32 is misaligned with the sensing unit 31, and the cover plate 22 covers the suction nozzle 11.

[0029] In this utility model, when the aerosol generating device 100 is in the off state, the cover plate 22 covers the suction nozzle 11 to prevent foreign objects from entering the aerosol generating device 100. The sensing unit 31 and the sensor unit 32 are misaligned. The sensor unit 32 detects that the signal of the sensing unit 31 has not reached the preset value, and the circuit of the aerosol generating device 100 is in the off state. When the user rotates the rotating part 21, it moves the cover plate 22 to open the suction nozzle 11. At the same time, the rotating part 21 moves the sensing unit 31 to align the sensing unit 31 and the sensor unit 32. The sensor unit 32 detects that the signal of the sensing unit 31 has reached the preset value. The sensor unit 32 transmits the signal to the main board 6 to trigger the circuit of the aerosol generating device 100 to start, and the aerosol generating device 100 enters the working state. The opening and closing of the nozzle 11 is achieved through the transmission cooperation between the rotating part 21 and the cover plate 22, which is simple in structure and occupies little space. The circuit control of the aerosol generating device 100 is achieved through the cooperation of the sensing part 31 and the sensor part 32, which improves the intelligence level of the aerosol generating device 100. Users only need to rotate the rotating part 21 to open and close the nozzle 11 and turn on and off the circuit function of the aerosol generating device 100. That is, the aerosol generating device 100 starts working when the nozzle 11 is opened, which eliminates the step of opening the cover and then starting the circuit function of the aerosol generating device 100, making the operation simple and convenient.

[0030] The mouthpiece 11 is used for the user to inhale the aerosol generated by the aerosol generating device 100 or for inserting a cartridge. The switch base 1 serves as a supporting component for the entire rotary switch structure, ensuring the stable installation and normal operation of other components. The rotating component 21 is rotatably mounted on the switch base 1. The user controls the rotation of the cover plate 22 and the opening and closing of the mouthpiece 11 by rotating the rotating component 21. The rotating component 21 is connected to the cover plate 22, ensuring that the cover plate 22 can move with the rotation of the rotating component 21, thereby enabling the cover plate 22 to open and cover the mouthpiece 11. The rotating component 21 is also provided with a sensing part 31. The main board 6 is located on the side of the switch base 1 facing away from the rotating component 21. The main board 6 is provided with a sensing part 32, which is used to detect the position change of the sensing part 31, thereby determining the open and closed state of the rotary switch structure and transmitting the signal to the main board 6 to control the circuit of the aerosol generating device 100. The sensing unit 32 and the sensing unit 31 can be a Hall sensor and a magnet (a magnet is provided on the rotating part 21, and when the rotating part 21 rotates to a specific position, the magnet will approach a Hall sensor, and the Hall sensor will trigger the circuit to start by detecting the change in the magnetic field), or a capacitive sensor and a conductive plate (a conductive plate is provided on the rotating part 21, and when the rotating part 21 rotates to a specific position, the conductive plate will approach a capacitive sensor, and the capacitive sensor will trigger the circuit to start by detecting the change in capacitance); or a magnetoresistive resistor and a magnet (a magnet is provided on the rotating part 21, and when the rotating part 21 rotates to a specific position, the magnet will approach a magnetoresistive resistor, and the magnetoresistive resistor will trigger the circuit to start by detecting the change in the magnetic field). This solution does not limit this.

[0031] Further, please refer to Figure 2The sensing element 3 includes two sensing units 31 and two sensing units 32. The two sensing units 31 are spaced apart from the rotating member 21, and the two sensing units 32 are spaced apart from the main board 6. Both sensing units 32 are electrically connected to the main board 6. The aerosol generating device 100 has a first-level mode and a second-level mode in the working state. In the first-level mode, one of the sensing units 31 is aligned with one of the sensing units 32. In the second-level mode, the other sensing unit 31 is aligned with the other sensing unit 32. When the aerosol generator 100 is in the first-level mode, one of the sensing units 31 is aligned with one of the sensing units 32. At this time, one of the sensing units 32 detects the signal of one of the sensing units 31. The main board 6 controls the aerosol generator 100 to operate in the first-level mode (normal mode) based on this signal. The first-level mode can be set to a lower power output, which is suitable for the user's needs when using it lightly. When the aerosol generator 100 is in the second-level mode, the other sensing unit 31 is aligned with the other sensing unit 32. Accordingly, the other sensing unit 32 detects the signal of the other sensing unit 31. The main board 6 controls the aerosol generator 100 to operate in the second-level mode (enhanced mode) based on this. The second-level mode can be set to a higher power output, which is to meet the user's needs when a more intense experience is required. With this design, users can easily switch the working mode of the aerosol generator 100 by simply rotating the rotating part 21. When the rotating part 21 is rotated to a specific position, different sensing parts 31 are aligned with the corresponding sensing parts 32, thereby realizing the switching of different modes. This improves the flexibility of the aerosol generator 100 and the user experience, and also enables the aerosol generator 100 to adapt to the usage needs of different scenarios.

[0032] Specifically, please refer to Figure 2 , Figure 7 , Figures 9 to 11In one embodiment, the rotating member 21 has a guide groove 211 on the side facing the switch base 1, and the cover plate 22 has a guide post 221 on the side facing away from the switch base 1 that slides with the guide groove 211. The guide groove 211 includes a connected arc segment 211a and an inclined arc segment 211b. The arc segment 211a is centered on the center of the rotating member 21, and the end of the inclined arc segment 211b away from the arc segment 211a extends toward the edge of the rotating member 21. In the first mode, the guide post 221 is located at the connection between the arc segment 211a and the inclined arc segment 211b, and one of the sensing parts 31 is aligned with one of the sensing parts 32. In the second mode, the guide post 221 is located at the end of the arc segment 211a away from the inclined arc segment 211b, and the other sensing part 31 is aligned with the other sensing part 32. When the aerosol generating device 100 is in the off state (as shown in the attached diagram of the instruction manual) Figure 9 As shown in the diagram, the cover plate 22 covers the nozzle opening 11 to prevent foreign objects from entering the aerosol generating device 100. The sensing unit 31 and the sensing unit 32 are misaligned. When the sensing unit 32 detects that the signal from the sensing unit 31 has not reached the preset value, the circuit of the aerosol generating device 100 is closed. When the user rotates the rotating part 21, the guide post 221 on the cover plate 22 rotates the cover plate 22 under the action of the two side walls of the inclined arc segment 211b until the guide post 221 is located at the junction of the arc segment 211a and the inclined arc segment 211b, at which point the nozzle opening 11 is fully opened (as shown in the attached diagram of the instruction manual). Figure 10 As shown in the diagram, at this time, one of the sensing units 31 and one of the sensing units 32 are aligned. The sensing unit 32 detects that the signal from the sensing unit 31 has reached a preset value, and the circuit of the aerosol generating device 100 is activated and enters the first mode (i.e., normal mode). When the user continues to rotate the rotating part 21, since the center of the arc segment 211a is the center of the rotating part 21, the cover plate 22 stops rotating when the rotating part 21 drives the guide post 221 to rotate within the arc segment 211a, while the rotating part 21 continues to rotate until the guide post 221 is located at the end of the arc segment 211a away from the inclined arc segment 211b (as shown in the attached diagram of the instruction manual). Figure 11 As shown), at this time, another sensing unit 31 is aligned with another sensing unit 32. The sensing unit 32 detects that the signal from the sensing unit 31 has reached a preset value, and the circuit of the aerosol generating device 100 is activated and enters the second-level mode (i.e., enhanced mode). Users can turn the aerosol generating device 100 on and off and switch between different working modes through a simple rotation operation. The design of the guide groove 211 not only ensures the precise movement of the cover plate 22, but also realizes intelligent control of the circuit through the alignment of the sensing unit 31 and the sensing unit 32. The structure is simple, the operation is convenient, and it can effectively prevent foreign objects from entering the interior of the aerosol generating device 100, thereby improving the reliability of the aerosol generating device 100 and the user experience.

[0033] To achieve a rotatable connection between the rotating component 21 and the switch base 1, please refer to... Figure 4 and Figure 8 In one embodiment, the switch base 1 has a first protrusion 12 on the side facing the rotating member 21, and the rotating member 21 has a second protrusion 212 on the side facing the switch base 1. The second protrusion 212 has a receiving groove 212a, and the first protrusion 12 is rotatably received in the receiving groove 212a. The outer peripheral wall of the first protrusion 12 has a hooking part 121, and the inner peripheral wall of the receiving groove 212a forms a limiting step 212b. The hooking part 121 is hooked to the limiting step 212b. The second protrusion 212 has a receiving groove 212a, and the first protrusion 12 is rotatably received in the receiving groove 212a. This structural design allows the rotating part 21 to rotate smoothly around the first protrusion 12 while maintaining a stable connection with the switch base 1. Through the cooperation of the hook part 121 and the limiting step 212b, the rotating part 21 can be effectively limited during rotation, avoiding separation from the switch base 1 due to external force, thereby ensuring the reliability and durability of the entire rotary switch structure.

[0034] Please see Figure 6 and Figure 8In one embodiment, the aerosol generating device 100 includes a ball bearing 4. The first protrusion 12 has a mounting groove 122 on the side facing the rotating member 21. The ball bearing 4 is elastically connected to the bottom wall of the mounting groove 122. The bottom wall of the receiving groove 212a has a plurality of grooves 212c spaced apart. The part of the ball bearing 4 exposed at the opening of the mounting groove 122 can be inserted into any of the grooves 212c. When the aerosol generating device 100 is off, the portion of the ball bearing 4 exposed in the groove of the mounting slot 122 is engaged in one of the recesses 212c. When the user rotates the rotating component 21, the ball bearing 4 moves into the mounting slot 122 under the pressure of the bottom wall of the receiving groove 212a until the rotating component 21 drives the cover plate 22 to open the suction nozzle 11. At this time, the aerosol generating device 100 is in the first gear mode, and the portion of the ball bearing 4 exposed in the groove of the mounting slot 122 is engaged in another recess 212c. The user continues to rotate the rotating component 21 until the aerosol generating device 100 is in the second gear mode, and the portion of the ball bearing 4 exposed in the groove of the mounting slot 122 is engaged in yet another recess 212c. The elastic arrangement of multiple recesses 212c and the ball bearing 4 allows the user to clearly feel the position of each gear during operation, improving the accuracy and reliability of operation. The bottom wall of the container 212a is provided with multiple grooves 212c spaced apart. The position and number of grooves 212c are designed according to the working mode and operation requirements of the aerosol generating device 100. By setting multiple grooves 212c, the aerosol generating device 100 can switch between multiple modes. When the user needs to switch modes, he only needs to gently rotate the rotating part 21. The ball 4 will be released from the current groove 212c and will be inserted into the next groove 212c during the rolling process, thereby realizing the mode switch. This design makes the operation process simple and intuitive, and the user can complete the mode switch without complicated operations. Through the cooperation of the ball 4 and the grooves 212c, precise positioning and multi-level switching functions are achieved, while maintaining the simplicity and compactness of the structure. There can be one ball 4 and two mounting grooves 122. When one ball 4 and mounting groove 122 are set, three grooves 212c are set accordingly. When two ball 4 and mounting groove 122 are set, six grooves 212c are set accordingly. This solution does not limit this number.

[0035] Please see Figure 6 and Figure 8In one embodiment, the aerosol generating device 100 includes an elastic element 5, with both ends of the elastic element 5 connected to the bottom wall of the mounting groove 122 and the ball bearing 4, respectively. The elastic element 5 (e.g., a spring) provides elastic support to the ball bearing 4 by connecting its two ends to the bottom wall of the mounting groove 122 and the ball bearing 4. When the ball bearing 4 is subjected to external force, the elastic element 5 allows the ball bearing 4 to extend and retract within a certain range, thereby achieving engagement and release between the ball bearing 4 and the groove 212c. When the aerosol generator 100 is in the off state, the ball bearing 4 is engaged in one of the grooves 212c under the action of the elastic element 5. At this time, the cover plate 22 covers the suction nozzle 11 to prevent foreign objects from entering the aerosol generator 100. When the user rotates the rotating part 21, the ball bearing 4 moves into the mounting groove 122 under the pressure of the bottom wall of the receiving groove 212a. When the rotating part 21 drives the cover plate 22 to open the suction nozzle 11, the ball bearing 4 is engaged in another groove 212c under the action of the elastic element 5. At this time, the aerosol generator 100 is in the first gear mode. When the user continues to rotate the rotating part 21, the ball bearing 4 is engaged in yet another groove 212c under the action of the elastic element 5. At this time, the aerosol generator 100 is in the second gear mode. The elastic setting of multiple grooves 212c and ball bearings 4 allows users to clearly feel the position of each gear during operation, improving the accuracy and reliability of operation. Users can turn the aerosol generator 100 on and off and switch between different working modes through simple rotation. The operation process is simple and intuitive.

[0036] In one embodiment, the switch base 1, the rotating component 21, and the cover plate 22 are all made of self-lubricating materials. Since the switch base 1, the rotating component 21, and the cover plate 22 are all made of self-lubricating materials, which have the characteristics of low friction coefficient and high wear resistance, using self-lubricating materials can reduce wear between components, extend service life, reduce maintenance costs, and provide a smoother rotation experience.

[0037] To achieve a rotatable connection between the cover plate 22 and the switch base 1, please refer to... Figure 8In one embodiment, a rotating shaft 222 is formed on the side of the cover plate 22 facing the switch base 1, and a positioning hole 13 is provided on the side of the switch base 1 facing the cover plate 22. The rotating shaft 222 is rotatably accommodated in the positioning hole 13. The rotating shaft 222 of the cover plate 22 is inserted into the positioning hole 13 of the switch base 1, allowing the cover plate 22 to rotate smoothly around the rotating shaft 222, ensuring a stable connection between the cover plate 22 and the switch base 1, while allowing the cover plate 22 to rotate freely during operation. When the user rotates the rotating component 21, the rotating shaft 222 on the cover plate 22 rotates accordingly within the positioning hole 13, thereby realizing the opening and closing action of the cover plate 22. This design not only realizes the rotatable function of the cover plate 22, but also ensures the smoothness and reliability of the rotation process through the cooperation between the rotating shaft 222 and the positioning hole 13. Through the cooperation between the rotating shaft 222 and the positioning hole 13, a rotatable connection between the cover plate 22 and the switch base 1 is realized. The structure is simple and compact, reducing the number of parts, lowering production costs, and improving the reliability and durability of the product.

[0038] Please see Figure 1 and Figure 5 In one embodiment, the aerosol generating device 100 includes a support 7 and a housing 8. The support 7 has a first opening 71 corresponding to the nozzle 11, and the switch base 1 is connected to the support 7. The housing 8 has a receiving cavity 81, in which the rotary switch structure and the support 7 are housed. One side wall of the receiving cavity 81 has a second opening 82 corresponding to the nozzle 11 and a third opening 83 corresponding to the rotating member 21, with the rotating member 21 exposed in the third opening 83. The bracket 7 aligns with the nozzle 11 through its first opening 71, ensuring unobstructed airflow through the nozzle 11. The switch base 1 connects to the bracket 7, providing stable support for the rotary switch structure. The rotary switch structure and bracket 7 are housed within the receiving cavity 81 of the housing 8. This design makes the entire aerosol generating device 100 more compact, reducing external dimensions and improving portability. The second opening 82 corresponds to the nozzle 11, allowing the user to directly access the nozzle 11 through the housing 8. The third opening 83 corresponds to the rotating component 21, exposing a portion of the rotating component 21 for easy operation. This design allows the user to directly access the nozzle 11 through the second opening 82 on the housing 8, while simultaneously switching modes and operating the switch via the rotating component 21 exposed in the third opening 83. This design not only improves operational convenience but also maintains the overall aesthetic appeal of the aerosol generating device 100.

[0039] Please see Figure 2 and Figure 4In one embodiment, the switch base 1 has a receiving groove 15 on the side facing the bracket 7. The aerosol generating device 100 includes an adhesive member 9, whose two sides are respectively bonded to the main board 6 and the bottom wall of the receiving groove 15. The adhesive member 9 firmly fixes the main board 6 in the receiving groove 15 of the switch base 1, ensuring that the main board 6 will not loosen or shift during use. The use of the adhesive member 9 reduces the use of mechanical connectors (such as screws, clips, etc.), simplifying the assembly process. The receiving groove 15 provides a dedicated installation space for the main board 6, making the structure of the entire aerosol generating device 100 more compact. The receiving groove 15 provides physical protection for the main board 6, preventing external impacts and collisions. The combined use of the adhesive member 9 and the receiving groove 15 ensures the stable fixation of the main board 6 on the switch base 1, reduces the use of mechanical connectors, and improves the reliability of the overall structure.

[0040] Please see Figure 2 and Figure 8 In one embodiment, a hook 14 is formed at one end of the switch base 1 near the bracket 7, and a groove 72 is formed at one end of the bracket 7 near the switch base 1. The hook 14 engages within the groove 72. The engaging structure of the hook 14 and the groove 72 provides a reliable mechanical connection, ensuring a firm connection between the switch base 1 and the bracket 7. This effectively prevents loosening or separation due to external forces during use. Pre-connection using the groove 72 and hook 14 is possible, followed by screw connection between the switch base 1 and the bracket 7, improving the overall stability and reliability of the product. The design of the hook 14 and groove 72 allows for quick disassembly and assembly, facilitating maintenance and repair. Users or maintenance personnel can easily disassemble and reinstall the switch base 1, improving product maintainability and reducing maintenance time and costs.

[0041] To improve the sealing performance of the aerosol generating device 100, please refer to [link / reference needed]. Figure 5 In one embodiment, the aerosol generating device 100 includes a sealing ring 16. The sealing ring 16 is fitted onto the outer peripheral wall of the switch base 1, and the sealing ring 16 elastically abuts against the inner peripheral wall of the receiving cavity 81. The elastic abutment between the sealing ring 16 and the inner peripheral wall of the receiving cavity 81 forms a tight seal, preventing dust, moisture, etc., from entering the interior of the aerosol generating device 100. This improves the dustproof and waterproof performance of the aerosol generating device 100, extends the product's service life, and reduces circuit failures caused by dust or moisture ingress. The elasticity of the sealing ring 16 can absorb some vibration, reducing the mechanical impact on the switch base 1 during use, improving the service life of the switch base 1, and reducing the risk of loose connections or damage caused by vibration.
