Description

Technical Field

[0001] This utility model relates to the field of aerosol technology, and in particular to an aerosol generating device. Background Technology

[0002] Aerosol generating devices are devices that convert liquid or solid substances into aerosols (i.e., tiny particles or droplets suspended in the air) through heating or atomization. They are widely used in electronic cigarettes, medical inhalers, air purification equipment, industrial spraying equipment, and other fields.

[0003] Taking e-cigarettes as an example, their core function lies in adjusting the flavor and number of puffs by controlling the heating temperature or heating time. However, most traditional e-cigarettes use software presets to fix the heating time, which cannot meet the user's need to adjust it in real time according to personal preferences. Users cannot adjust the heating parameters according to their personal preferences during use, resulting in low versatility and personalization of the product. Utility Model Content

[0021] This utility model proposes an aerosol generating device 100.

[0022] Please see Figure 2 In one embodiment of this utility model, the aerosol generating device 100 includes a rotary switch structure 1 and a main board 2. The rotary switch structure 1 includes a base 11 and a knob 12, the knob 12 being rotatably disposed on the base 11. The main board 2 is disposed on the side of the base 11 facing away from the knob 12. A plurality of microswitches 21 are spaced apart on the side of the main board 2 near the base 11, and each microswitch 21 is electrically connected to a main board 2. The knob 12 is configured to trigger at least one of the microswitches 21 when rotated.

[0023] In this technical solution, when the user rotates the knob 12, the knob 12 triggers a different number of microswitches 21, thereby switching the operating state of the aerosol generating device 100. Specifically, when the user rotates the knob 12 to the first position, one microswitch 21 is triggered, and the main board 2 controls the aerosol generating device 100 to enter the first operating state, such as heating at a lower temperature or for a shorter time; when the knob 12 is rotated to the second position, two microswitches 21 are triggered, and the main board 2 controls the device to enter the second operating state, such as heating at a medium temperature or for a medium time; when the knob 12 is rotated to the third position, three microswitches 21 are triggered, and the main board 2 controls the device to enter the third operating state, such as heating at a higher temperature or for a longer time. In this way, the user can adjust the heating parameters in real time according to personal preferences, realizing personalized control over the cigarette taste and the number of puffs. The aerosol generating device 100 provided by this utility model can solve the problems of traditional aerosol generating devices 100 being unable to adjust heating parameters in real time and having a limited user experience by adopting a combination design of a knob switch structure 1 and multiple micro switches 21.

[0024] One method for the knob 12 to trigger the micro switch 21 is to position the trigger end of the micro switch 21 within the rotation stroke of the knob 12. Specifically, the knob 12 has a trigger segment 121 for triggering the micro switch 21. This trigger segment 121 can abut against the trigger end of at least one micro switch 21 during the rotation of the knob 12, thereby triggering the micro switch 21. Alternatively, the knob 12 can trigger the micro switch 21 by providing a lever on the knob 12. When the knob 12 rotates, the lever sequentially moves the micro switches 21 to different positions, achieving switching between different gears. Another method is to provide a magnetic element (such as a magnet) on the knob 12, and the micro switch 21 on the main board 2 is a magnetic switch (such as a reed switch or Hall effect switch). When the knob 12 rotates, the magnetic element approaches the magnetic switch, triggering the switch to operate, using non-contact triggering. This solution does not impose any restrictions on this method.

[0025] Please see Figure 2 In one embodiment, the trigger ends of each microswitch 21 are exposed on the main board 2, and the knob 12 has a trigger segment 121 on the side facing the main board 2 for abutting the trigger ends. The trigger ends of each microswitch 21 are exposed on the surface of the main board 2, and the trigger segment 121 of the knob 12 abuts against the trigger ends of the microswitches 21 during its rotation stroke. When the user rotates the knob 12, the trigger segment 121 rotates synchronously with the knob 12 and abuts against the trigger ends of the microswitches 21 at different positions in sequence during the rotation, thereby triggering the corresponding microswitches 21. By triggering different numbers of microswitches 21, the switching control of different levels of the aerosol generating device 100 can be achieved. Users can quickly switch between different levels by rotating the knob 12, meeting the personalized usage needs of different users for the aerosol generating device 100.

[0026] To prevent the knob 12 from detaching from the base 11 during rotation, please refer to... Figure 2 and Figure 3In one embodiment, the knob 12 has a groove 122 on the side facing the base 11, and an annular protrusion 111 is formed on the end of the base 11 near the knob 12. The annular protrusion 111 is accommodated in the groove 122. A hook 123 is formed on the side wall of the groove 122, and the hook 123 is hooked to the annular protrusion 111. The receiving groove 122 is a circular groove 124 structure used to accommodate the annular protrusion 111 on the base 11, thereby achieving a compact layout of the rotary switch structure 1 and effectively reducing the overall volume. A hook 123 is also formed on the side wall of the receiving groove 122, extending towards the annular protrusion 111 and engaging with the edge of the annular protrusion 111. The hook 123 has a certain elastic deformation capability; during assembly, the hook 123 can slightly open to allow the annular protrusion 111 to enter the receiving groove 122, and returns to its original shape after the annular protrusion 111 is fully inside, thus achieving the engagement between the hook 123 and the annular protrusion 111 and preventing the knob 12 from axially dislodging. Through the above structural design, the knob 12 can be stably installed on the base 11 and maintain smooth rotation performance during user operation, while possessing good assembly reliability and structural stability, effectively improving the service life and operating feel of the aerosol generating device 100.

[0027] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5In one embodiment, the rotary switch structure 1 includes a limiting member 13. A protrusion 112 is formed on the side of the base 11 facing the rotary member 12. The limiting member 13 is sleeved on the protrusion 112 and elastically connected to the base 11. The bottom wall of the receiving groove 122 has multiple grooves 124. A limiting protrusion 134 is formed on the side of the limiting member 13 facing the rotary member 12. The limiting protrusion 134 can be engaged in any of the grooves 124. Each groove 124 corresponds to a micro switch 21. When the user rotates the rotary member 12, the limiting protrusion 134 slides out of one groove 124, and the limiting member 13 moves away from the rotary member 12. When the rotary member 12 rotates to the next position, the limiting protrusion 134 engages in the next groove 124, simultaneously triggering the corresponding micro switch 21. Under the action of elastic restoring force, the limiting member 13 moves closer to the rotary member 12. Through the cooperation of the limiting member 13 and the groove 124, the user can clearly perceive the gear shift, improving the accuracy of operation and user experience. Before the knob 12 enters the next gear, the limiting protrusion 134 contacts the bottom wall of the groove 122 to generate friction, so that the knob 12 has a certain damping effect during rotation. This damping effect can provide the user with a clear sense of rotational resistance, preventing the knob 12 from rotating freely or being misoperated without external force, thus improving the stability and accuracy of user operation. At the same time, the damping effect can also effectively reduce the shaking or vibration of the knob 12 during rotation, making gear shifting smoother and more stable, further improving the user experience.

[0028] Specifically, please refer to Figure 2In one embodiment, the rotary switch structure 1 includes an elastic element 15. The base 11 has a receiving groove 114, and the bottom wall of the receiving groove 114 forms the protrusion 112. The elastic element 15 is sleeved on the protrusion 112 and is located between the bottom wall of the receiving groove 114 and the limiting member 13. The elastic element 15 provides elastic support for the limiting member 13, ensuring that the limiting member 13 can be stably engaged in the groove 124 during the rotation of the knob 12, thereby achieving a reliable gear positioning function. The elastic element 15 can be a compression spring, a sheet spring, or other elastic elements to provide a stable elastic restoring force. When the user rotates the knob 12, the limiting member 13 is squeezed by the bottom wall of the receiving groove 122, compressing the elastic member 15 and moving towards the bottom wall of the receiving groove 114. When the knob 12 is rotated to the next position, the limiting member 13, under the elastic restoring force of the elastic member 15, moves away from the bottom wall of the receiving groove 114, and the limiting protrusion 134 engages in the corresponding groove 124 on the bottom wall of the receiving groove 122, simultaneously triggering the corresponding micro switch 21 to achieve gear switching. The elastic member 15 provides stable elastic support for the limiting member 13, ensuring that the limiting member 13 can reliably engage in the groove 124, improving the gear positioning accuracy and operational stability of the knob switch structure 1.

[0029] Please see Figure 2 In one embodiment, the inner peripheral wall of the receiving groove 114 is formed with an annular limiting step 115, and the end of the limiting member 13 away from the base 11 is formed with an annular limiting boss 133. A first gap space 14 is formed between the annular limiting step 115 and the annular limiting boss 133. The first gap space 14 is provided to allow for the vertical movement of the limiting member 13, ensuring that the limiting member 13 has a certain amount of axial movement space when squeezed by the knob member 12 or rebounded by the elastic member 15, thereby achieving smooth gear switching and reliable elastic reset.

[0030] To prevent the limit member 13 from rotating, please refer to Figure 4 and Figure 5In one embodiment, the outer peripheral wall of the protrusion 112 is formed with a positioning protrusion 113, and the limiting member 13 is provided with a through groove 131. The inner peripheral wall of the through groove 131 is formed with a positioning groove 132, and the positioning protrusion 113 is inserted into the positioning groove 132. When the knob 12 is rotated, due to the cooperation between the positioning protrusion 113 and the positioning groove 132, the limiting member 13 is restricted on the protrusion 112 and cannot rotate with the knob 12, but can only move in the axial direction. Therefore, under the squeezing of the knob 12 or the rebound of the elastic member 15, the limiting member 13 can stably move up and down, ensuring the accuracy and stability of gear switching. Through the cooperation between the positioning protrusion 113 and the positioning groove 132, the limiting member 13 can be effectively prevented from rotating when the knob 12 is rotated, ensuring that the limiting member 13 only moves in the axial direction, thereby realizing a stable gear switching function.

[0031] Please see Figure 2 In one embodiment, the bottom wall of the receiving groove 122 is provided with a mounting groove 125. A portion of the protrusion 112 is accommodated within the mounting groove 125, forming a second gap space 16 with the bottom wall of the mounting groove 125. When the user rotates the knob 12, the protrusion 112 is accommodated within the mounting groove 125. Due to the presence of the second gap space 16, the protrusion 112 will not directly contact the bottom wall of the mounting groove 125, effectively preventing interference and friction between the protrusion 112 and the bottom wall of the receiving groove 122. This ensures smooth rotation of the knob 12 and improves the service life and reliability of the rotary switch structure 1. Furthermore, the protrusion 112 and the mounting groove 125 also provide positioning for the assembly of the knob 12 and the base 11, enabling precise installation of the knob 12 and the base 11. This effectively improves the assembly accuracy of the knob 12 and the base 11, simplifies the assembly process, reduces assembly errors, and enhances the overall structural stability and reliability.

[0032] Please see Figure 2 , Figure 3 as well as Figure 4 In one embodiment, the bottom wall of the receiving groove 122 forms a limiting block 126, and the annular protrusion 111 has an annular limiting groove 116 formed on the side facing the knob 12. The limiting block 126 is accommodated within the annular limiting groove 116. When the user rotates the knob 12, the limiting block 126 moves within the annular limiting groove 116. Due to the blocking effect of the groove wall of the annular limiting groove 116 on the limiting block 126, the rotation stroke of the knob 12 is limited within the range of the annular limiting groove 116, thereby preventing the knob 12 from rotating excessively and ensuring the accuracy and reliability of gear switching.

[0033] Please see Figure 1In another embodiment, the rotary switch structure 1 includes a rotating upper shell 17, which is detachably connected to the side of the knob 12 facing away from the base 11. The aerosol generating device 100 includes a housing 3, which has a cavity 31 with an opening. The base 11, the knob 12, and the main board 2 are all housed within the cavity 31, and the rotating upper shell 17 is exposed outside the housing 3. The knob 12 and the rotating upper shell 17 are detachably connected, for example, by means of snaps, threads, or screws. The aerosol generating device 100 also includes a housing 3, which has a cavity 31 with an opening. The base 11, the knob 12, and the main board 2 are all housed within the cavity 31, and the rotating upper shell 17 is exposed outside the housing 3 for user operation. Through the above structural design, the user can rotate the rotating upper shell 17 exposed outside the housing 3 to drive the knob 12 to rotate synchronously, thereby triggering the micro switch 21 to achieve gear switching. In the specific assembly process of the device, first fix the rotating upper shell 17 and the knob 12 with screws, and assemble the base 11, the elastic element 15 and the limiting element 13. Then, hook the hook 123 on the knob 12 to the annular protrusion 111 on the base 11, put the assembled knob switch structure 1 into the cavity 31 of the housing 3, and finally connect the main board 2 to the base 11 and the housing 3.
