DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] Referring to Figures 1 to 7, with particular reference to Figures 1, 2, and 3, an embodiment of an aerosol generating device provided by the present application is illustrated. The structure and operating principle of the aerosol generating device will be described in detail below in conjunction with the accompanying drawings. The aerosol generating device comprises: a housing 10, a PCB board 30, an air regulating ring 20, and a detection member 31. The housing 10 is provided with an air inlet 11. The PCB board 30 is fixedly mounted in the housing 10. The air regulating ring 20 is rotatably mounted on the housing 10. The air regulating ring 20 is provided with an air regulating portion 22 and a radially arranged adjustment rod 21. The detection member 31 is disposed on the PCB board 30 and rotatably connected to the adjustment rod 21. The detection member 31 is configured to detect the rotation angle of the detection member 31 when the air regulating ring 20 rotates about the housing 10. The PCB board 30 is configured to adjust the power according to the rotation angle of the detection member 31. When the air regulating ring 20 rotates about the housing 10, the air regulating portion 22 partially or completely closes the air inlet 11.

[0033] In this embodiment, the shell 10 is rod-shaped, and the top is in the shape of a suction nozzle 53. The air inlet 11 on the shell 10 passes through the inside and outside of the shell 10. The air adjustment ring 20 can be set and installed at any position on the shell 10, usually in the center or near the center of the rod-shaped shell 10, which is more convenient to adjust. The air adjustment ring 20 can rotate around the shell 10 at a certain angle. The adjustment rod 21 is set in the radial direction of the air adjustment ring 20 and is integrated with the air adjustment ring 20. It extends from the inner wall 23 or end surface of the air adjustment ring 20 to the center of the air adjustment ring 20. The adjustment rod 21 can also be set to cross the entire air adjustment ring 20. In addition to the basic atomization control and charging functions of the PCB board of a conventional aerosol generating device, the PCB board 30 also has the function of power control and adjustment. The detection member 31 is fixedly arranged on the PCB board 30 and is connected to the PCB board 30. The CB board 30 is electrically connected, and the detection member 31 can specifically be a rotary switch, a rotary positioner, an encoder, a rheostat, etc. The detection member 31 itself can change the internal electrical parameters of the PCB board 30 by rotating, so that the PCB board 30 makes corresponding parameter adjustments according to the changes. The adjustment rod 21 is rotationally connected to the detection member 31 on the PCB board 30. When the air adjustment ring 20 is rotated, the adjustment rod 21 will drive the detection member 31 to rotate synchronously. The air adjustment portion 22 on the air adjustment ring 20 is used to open or close the air inlet 11, so that the air intake area of ​​the air inlet 11 changes. While the adjustment rod 21 drives the detection member 31 to rotate synchronously, the air adjustment portion 22 on the air adjustment ring 20 makes corresponding adjustments to the air intake area of ​​the air inlet 11, and the air intake area of ​​the air inlet 11 changes with the rotation of the air adjustment ring 20. In this application, "area" refers to the area in the radial direction perpendicular to the air adjustment ring 20.

[0034] By implementing this embodiment, the air adjustment ring 20 rotates around the housing 10. When the air adjustment ring 20 is rotated, the adjustment rod 21 on the air adjustment ring 20 will drive the detection member 31 on the PCB board 30 to rotate, causing the internal electrical parameters of the PCB board 30 to change. The PCB board 30 adjusts the output power accordingly based on the change in the rotation angle of the detection member 31. At the same time as the air adjustment ring 20 is rotated, the air adjustment portion 22 on the air adjustment ring 20 will adjust the air intake area of ​​the air inlet 11 provided on the housing 10 by opening or closing, and the air intake volume through the air inlet 11 will change. When the air adjustment ring 20 rotates the corresponding angle, the adjustment rod 21 simultaneously drives the detection member 31 to rotate the corresponding angle, and the air intake area of ​​the air inlet 11 is synchronously changed and the corresponding air intake volume is circulated, thereby achieving synchronous adjustment of power and air intake volume. The synchronous control of power and air intake volume becomes more precise, the synchronization effect becomes more ideal, the overall atomization effect of the device becomes better, and the user experience is better.

[0035] In one embodiment, referring to FIG3 , the air regulating portion 22 is an air regulating port. When the air regulating ring 20 rotates around the housing 10, the air regulating port partially or completely overlaps with the air inlet 11. The air regulating portion 22 is designed as an air regulating port on the air regulating ring 20. When the air regulating ring 20 rotates, the overlapping portion of the air inlet 11 and the air regulating port forms an air intake channel. The area of ​​this channel changes with the rotation angle of the air regulating ring 20. When the air inlet 11 and the air regulating port completely overlap, the air intake channel area is maximized, and the air intake volume is also maximized. Specifically, the air inlet 11 and the air regulating port can be configured as the same strip-shaped port. In this way, the effective adjustment area of ​​the air regulating ring 20 is increased, and the adjustment range of the air regulating ring 20 is also increased, meeting the adjustment requirements of more gears.

[0036] In one embodiment, referring to Figures 2 and 3, a limiting groove 12 is further provided on the shell 10, and the limiting groove 12 includes a first groove wall 120 and a second groove wall 121 separated and arranged along the radial direction of the air adjusting ring 20. The adjusting rod 21 is inserted into the limiting groove 12. When the air adjusting ring 20 rotates around the shell 10, the adjusting rod 21 stops the first groove wall 120 or the second groove wall 121 along one of the two sides perpendicular to the radial direction of the air adjusting ring 20. Specifically, the limit groove 12 passes through the inside and outside of the shell 10, and has a certain length in the circumferential direction of the rod-shaped shell 10. The specific length can be designed according to the maximum rotation angle of the detection part 31. The adjusting rod 21 passes through the limit groove 12 from the air-adjusting ring 20 and is connected to the detection part 31. After rotating the air-adjusting ring 20 at a certain angle, the adjusting rod 21 will stop on one of the two sides of the radial direction perpendicular to the air-adjusting ring 20 at the first groove wall 120 or the second groove wall 121 on the limit groove 12. After stopping, the air-adjusting ring 20 cannot continue to rotate forward and can only rotate in the other direction, thereby limiting the overall formation of the air-adjusting ring 20.

[0037] Furthermore, when the distances between the adjusting rod 21 and the first groove wall 120 and the second groove wall 121 on both sides perpendicular to the radial direction of the air regulating ring 20 are equal, the air regulating port and the air inlet 11 completely overlap. Specifically, the distances between the adjusting rod 21 and the first groove wall 120 and the second groove wall 121 on both sides of the radial direction of the air regulating ring 20 are equal, that is, when the adjusting rod 21 is located at the center of the limiting groove 12, the air inlet 11 completely overlaps with the air regulating port, forming a maximum air intake channel area and a maximum air intake volume. In this state, the corresponding power setting on the PCB board 30 is set to maximum power. When the air regulating ring 20 continues to rotate, the air inlet 11 and the air regulating port only partially overlap, forming an air intake channel area that gradually decreases with rotation, and the air intake volume gradually decreases. In this state, the corresponding power setting on the PCB board 30 is gradually reduced, thereby achieving overall synchronization of power and air intake volume with the rotation angle of the air regulating ring 20, making adjustment very convenient.

[0038] Furthermore, two air inlets 11 and two air regulating ports are each provided. When the distances from the regulating rod 21 to the first groove wall 120 and the second groove wall 121 on both sides perpendicular to the radial direction of the air regulating ring 20 are equal, the two air regulating ports completely overlap with the two air inlets 11. Setting a single air inlet 11 and air regulating port sometimes cannot meet the requirements of synchronization of intake volume and power. This can be solved by setting multiple air inlets 11 and a corresponding number of air regulating ports. Here, two air inlets 11 and two air regulating ports are each provided. The two air inlets 11 are spaced apart at an appropriately large distance. The two air regulating ports correspond to the positions of the two air inlets 11. When the air regulating ring 20 is rotated, the non-corresponding air regulating ports will not affect the air inlets 11. When the distances between the adjustment rod 21 and the first and second groove walls 120, 121 on either side, perpendicular to the radial direction of the air-regulating ring 20, are equal, the two air inlets 11 completely overlap with the two air-regulating ports, forming two air-inlet passages. At this point, the area of ​​the two air-inlet passages is also maximized, and the amount of air passing through reaches its maximum. In this state, the corresponding power on the PCB board 30 can be set to maximum power. As the air-regulating ring 20 continues to rotate, the two air inlets 11 partially overlap with the two air-regulating ports, forming two air-inlet passages whose area gradually decreases with rotation, and the overall amount of air passing through gradually decreases. In this state, the corresponding power setting on the PCB board 30 gradually decreases. The overall provision of two air inlets 11 and the air-regulating ports can more effectively achieve the requirement of synchronizing air intake and power.

[0039] In one embodiment, referring to Figures 2 and 3, an annular portion 13 is provided on the housing 10. The outer diameter of the annular portion 13 is smaller than the inner diameter of the air regulating ring 20. The air inlet 11 is provided on the annular portion 13. The air regulating ring 20 is sleeved on the annular portion 13 and is rotatable around the annular portion 13. The annular portion 13 can be provided near the center of the rod-shaped housing 10 and can specifically be an annular groove provided around the housing 10. The air inlet 11 is provided on the annular portion 13 and passes through the inside and outside of the housing 10. The air regulating ring 20 is sleeved on the annular portion 13. The outer annular surface of the annular portion 13 is in contact with the inner annular surface of the air regulating ring 20. The air regulating ring 20 as a whole rotates around the outer annular surface of the annular portion 13 with the annular portion 13 as the rotation axis, thereby achieving synchronous adjustment of the intake volume and power.

[0040] Furthermore, the housing 10 includes an upper shell 101 and a lower shell 102, and an annular portion 13 is provided on the upper shell 101 and / or the lower shell 102, and the upper shell 101 and / or the lower shell 102 are sleeved on the annular portion 13. The annular portion 13 can be provided at the portion where the upper shell 101 and the lower shell 102 are joined, or at the portion where the lower shell 102 and the upper shell 101 are joined, and is specifically provided here at the portion where the lower shell 102 and the upper shell 101 are joined. After the air adjustment ring 20 is sleeved on the annular portion 13, a portion of the annular portion 13 extends outward, and the upper shell 101 can be fixedly sleeved on the portion extending from the annular portion 13. A thread can be provided on the portion extending from the annular portion 13, and the inner wall on one side where the upper shell 101 and the lower shell 102 are joined is provided with a thread groove adapted to the thread, and is secured by thread locking, making the overall assembly more convenient and facilitating inspection and maintenance.

[0041] In one embodiment, referring to Figures 4 to 6, the detection member 31 includes a connecting portion 311 and a sensing portion 310. The sensing portion 310 is fixed to the PCB board 30. The connecting portion 311 is rotatably connected to the sensing portion 310. The adjusting rod 21 is fixed to the connecting portion 311. When the air adjustment ring 20 rotates around the housing 10, the adjusting rod 21 drives the connecting portion 311 to rotate around the sensing portion 310. Specifically, the sensing part 310 is the part of the detection member 31 fixed on the PCB board 30, which is used to sense the rotation angle of the connecting part 311 and generate electrical parameter changes according to the rotation angle. The connecting part 311 is rotatably connected to the sensing part 310 and can rotate a certain angle relative to the sensing part 310. During rotation, the sensing part 310 can sense the change in the rotation angle of the connecting part 311. The adjusting rod 21 is fixed on the connecting part 311. A groove 301 can be set on the connecting part 311 along the radial direction of the air adjusting ring 20, and the adjusting rod 21 is transversely fixed in the groove 301. Not only is the connection stable, but also it is convenient for disassembly. When the air adjusting ring 20 is rotated, the adjusting rod 21 will drive the connecting part 311 to rotate around the sensing part 310. The connecting part 311 rotates a corresponding angle relative to the sensing part 310 as the air adjusting ring 20 rotates. The two rotate at the same angle, and the power control is more precise.

[0042] In one embodiment, as shown in Figure 7, the aerosol generating device also includes a bottom cover 40, a TOP-C board 41, a microphone silicone seat 42, an EVA pad 43, a battery 44, an insulating silicone 45, an atomizer rod bracket 46, a sealing silicone 47, an oil-absorbing cotton 48, a ceramic heating wire 49, an atomizer rod 50, an oil tank 51, a suction nozzle sealing silicone 52, a suction nozzle 53 and other components.

[0043] The present application can realize synchronous adjustment of air intake and power by rotating the air adjustment ring as a whole. The synchronous adjustment and control of air intake and power becomes more precise and convenient, the overall atomization effect of the device is better, the user experience is improved, and it is more in line with market demand.
