[0037] Various embodiments of the present application can exist in a range of forms; it should be understood that the description in a range form is merely for the convenience and brevity, and should not be understood as a hard limitation to the scope of the present application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single values within the range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single values within the range, such as 1, 2, 3, 4, 5, and 6, which is applicable to any range. In addition, whenever a numerical range is indicated in the present text, it refers to any cited number (fraction or integer) within the indicated range.

[0038] Reference should be made to Figures 1 to 3 A knob 100 switch structure, the knob 100 switch structure comprising:

[0039] The knob 100 is provided with a containing groove 10;

[0040] The rotating assembly is located in the containing groove 10, and is rotatably connected to the knob 100, and the rotating assembly is used for detecting the amplitude of rotation of the knob 100 relative to the rotating assembly;

[0041] The elastic member 400 is located between the rotating assembly and the knob 100, and is in interference fit with the knob 100 and the rotating assembly.

[0042] In the embodiment, the rotating assembly can detect the amplitude of rotation of the knob 100 relative to the rotating assembly, and then determine the opening or closing state of the knob 100 switch structure through the amplitude of rotation of the rotating assembly. Since the elastic member 400 is located between the rotating assembly and the knob 100, and is in interference fit with the knob 100 and the rotating assembly, when the knob 100 rotates relative to the rotating assembly, the elastic member 400 can provide a resistance through its elastic deformation and / or friction, thereby allowing the user to feel the force that hinders the rotation of the knob 100, improving the feel of rotating the knob 100; at the same time, it also allows the user to realize the current rotation amplitude of the knob 100 without using the naked eye, improving the use efficiency of the knob 100 switch structure; then, since the elastic member 400 can provide a certain resistance, when the knob 100 is mistakenly touched and has a tendency to rotate, as long as the mistaken touch force is less than the range of the resistance, the knob 100 can be prevented from being mistakenly touched and rotated.

[0043] In summary, the elastic member 400 of the embodiment of the present application can prevent the knob 100 switch structure from being mistakenly started, improve its use efficiency and use feel.

[0044] It should be understood that the elastic member 400 can be damping silica gel. The knob 100 can include an abutting portion 110 located in the accommodating groove 10. The detection assembly can include the rotating member 200 located in the accommodating groove 10 and connected to the knob 100 in a rotating manner, and the detection member 300 including a main body 320 connected to the rotating member 200 and a detection portion 310 at least partially located in the accommodating groove 10 and moving along a rotating path in the accommodating groove 10, wherein the abutting portion 110 is located on the rotating path and used to abut against the detection portion 310.

[0045] Since the rotating member 200 is connected to the knob 100 in a rotating manner and the main body 320 is connected to the rotating member 200, when it is required to start the switch structure of the knob 100, the knob 100 can be driven to rotate in the opposite direction of the rotating path 30, at this time, the relative position between the knob 100 and the detection portion 310 changes, which can be regarded as the movement of the detection portion 310 along the rotating path 30. Since the abutting portion 110 is located on the rotating path 30, the detection portion 310 will contact the abutting portion 110 after moving a certain distance (as shown in FIG. 3B). Figure 2 After the detection portion 310 contacts the abutting portion 110, the main body 320 will sense that the detection portion 310 is abutted, thereby triggering a start signal to start the switch structure of the knob 100. When it is required to close the switch structure of the knob 100, the knob 100 can be driven to rotate along the rotating path 30, at this time, the detection portion 310 will be separated from the abutting portion 110 (as shown in FIG. 3C). Figure 4 After the detection portion 310 contacts the abutting portion 110, the main body 320 will sense that the detection portion 310 is abutted, thereby triggering a start signal to start the switch structure of the knob 100. When it is required to close the switch structure of the knob 100, the knob 100 can be driven to rotate along the rotating path 30, at this time, the detection portion 310 will be separated from the abutting portion 110 (as shown in FIG. 3C). Figure 5 After the detection portion 310 contacts the abutting portion 110, the main body 320 will sense that the detection portion 310 is abutted, thereby triggering a start signal to start the switch structure of the knob 100. When it is required to close the switch structure of the knob 100, the knob 100 can be driven to rotate along the rotating path 30, at this time, the detection portion 310 will be separated from the abutting portion 110 (as shown in FIG. 3C).

[0046] The structure of the detection assembly described above is only one kind of cooperation relationship between the knob 100 and the rotating assembly, in fact, the detection assembly and the rotating member 200 can also trigger a switch signal through structures such as infrared detection devices and magnetic induction devices. For example, when an infrared detection device is used, an infrared ray can be arranged on the rotating member 200 and a shielding member can be arranged on the knob 100, when the knob 100 rotates relative to the rotating member 200, the shielding member can combine the infrared detection device, at this time, it is set that the switch structure of the knob 100 enters an open state, when the knob 100 rotates relative to the rotating assembly and returns to the original position, the shielding member no longer shields the infrared detection device, at this time, it is set that the switch structure of the knob 100 enters a closed state, thereby achieving the effect of starting or closing the switch structure of the knob 100 through the detection result of the infrared detection device.

[0047] If the elastic member 400 is a whole structure such as a disc, it can form a circular friction force bearing surface during the rotation of the knob 100, but it occupies a large space, so that the detection part 310 and other remaining devices in the accommodation groove 10 cannot be accommodated, and the knob 100 switch structure and the atomization device are large in size, which is not convenient for carrying.

[0048] Further, please refer to Figures 1 to 3 , the elastic member 400 includes a first elastic part 410 and a second elastic part 420, the first elastic part 410 is provided with a first through hole 423, the second elastic part 420 is located in the first through hole 423, and the two ends of the second elastic part 420 are connected to the side wall of the first through hole 423.

[0049] In this embodiment, because the two ends of the second elastic part 420 are connected to the side wall of the first through hole 423, the first elastic part 410 and the second elastic part 420 intersect, and the two intersection lines can determine a plane, so the intersecting first elastic part 410 and second elastic part 420 can play the role of plane fixation, limiting the elastic member 400 in the accommodation groove 10, avoiding it from rolling in the accommodation groove 10 and slipping out of the accommodation groove 10.

[0050] Further, please refer to Figures 1 to 3 , the first elastic part 410 is annular, the second elastic part 420 is arranged on the axis of the first through hole 423, and the first through hole 423 is divided into two sub-through holes 440 of equal size.

[0051] In this embodiment, when the knob 100 rotates around Figure 4 Z axis, the second elastic part 420 can form a complete circle relative to the rotation path of the rotating assembly or the knob 100, that is, the friction force of the elastic member 400 applied to the knob 100 and / or the rotating assembly can be effectively increased, thereby further avoiding accidental touch. The two sub-through holes 440 can provide space for the assembly of the remaining devices inside the atomization device, thereby improving the utilization rate of the knob 100 switch structure; at the same time, because the sizes of the two sub-through holes 400 are the same, the structure of the elastic member 400 is symmetrical, and the structural stability of the knob switch mechanism is improved.

[0052] Further, please refer to Figures 1 to 5 , the side of the rotating assembly facing the knob 100 is provided with a rotating shaft 210, the knob 100 is provided with a second through hole 120, and at least part of the rotating shaft 210 is arranged in the second through hole 120.

[0053] The second elastic part 420 includes an elastic ring 421 and two connecting parts 422, the rotating shaft 210 is arranged in the elastic ring 421, and the two connecting parts 422 are oppositely arranged and connected to the side wall of the elastic ring 421 and the first through hole 423.

[0054] In the embodiment, the cooperation between the rotating shaft 210 and the second through hole 120 can enable the knob 100 and the rotating assembly to rotate around the rotating shaft 210, and avoid the knob 100 from being separated from the rotating shaft 210. The rotating shaft 210 located in the elastic ring 421 can avoid the elastic member 400 from being separated from the preset position. It should be understood that the elastic ring 421 can be directly sleeved on the side wall of the rotating shaft 210, or there is a gap between the elastic ring 421 and the rotating shaft 210, and the gap can accommodate another annular structure for fixing the rotating shaft 210. It should be understood that the number of the connecting portions 422 can also be three, four, etc., and when the number of the connecting portions 422 is greater than two, the connecting portions 422 can be distributed around the rotating shaft 210 in axial symmetry.

[0055] Further, referring to Figures 1 to 3 The knob 100 switch further includes a fixing member 500 and a screw 600. The fixing member 500 is provided with a positioning through hole 510, and is located on the side of the knob 100 away from the rotating assembly. The rotating shaft 210 is provided with a positioning protrusion 211 on the side facing the knob 100. The positioning protrusion 211 is arranged in the positioning through hole 510. The screw 600 is arranged in the fixing member 500 and is threadedly connected to the rotating assembly. The head of the screw 600 abuts against the side of the fixing member 500 away from the knob 100.

[0056] In the embodiment, the combination of the fixing member 500, the screw 600 and the rotating member 200 can clamp the knob 100 between the fixing member 500 and the rotating assembly, and does not affect the rotation of the knob 100. The screw 600 provides the main clamping force, and the fixing member 500 increases the force receiving area of the knob 100 to avoid the knob 100 from being tilted during rotation.

[0057] Further, referring to Figures 1 to 3 The width of the first elastic portion 410 is less than the width of the connecting portion 422 along the width direction of the first through hole 423; and / or,

[0058] The width of the first elastic portion 410 is equal to the width of the elastic ring 421.

[0059] In the embodiment, because the area swept by the second elastic portion 420 during the rotation of the knob 100 is a circle in the orthographic projection of the rotating assembly, the friction force borne by the second elastic portion 420 is generally greater than that borne by the first elastic portion 410. Therefore, the width of the second elastic portion 420 can be greater than the width of the first elastic portion 410. The width direction of the first elastic portion 410 is from the center of the first through hole 423 to the first through hole 423, and the width direction of the second elastic portion 420 is the rotation direction (the direction of the rotation path) of the knob 100.

[0060] Further, referring to Figures 1 to 3The connecting part between the second elastic part 420 and the side wall of the first through hole 423 is provided with a reinforcing rib 430, and the reinforcing rib 430 is provided with a connecting arc surface which is recessed towards the connecting part between the second elastic part 420 and the side wall of the first through hole 423.

[0061] In the embodiment, when the first elastic part 410 rotates along the rotating path, the connecting part between the first elastic part 410 and the second elastic part 420 will be subjected to a shearing force due to the different friction forces received by the first elastic part 410 and the second elastic part 420, and at this time, the reinforcing rib 430 can avoid the fracture of the connecting part; meanwhile, the reinforcing rib 430 is also provided with the connecting arc surface which is recessed towards the connecting part, so that the connecting arc surface can evenly distribute the force on each part of the reinforcing rib 430 when the reinforcing rib 430 is subjected to the shearing force, thereby further improving the stability of the elastic part 400 and avoiding the fracture thereof.

[0062] Further, as shown in Figures 1 to 3 The knob 100 is also provided with a first mounting groove 130 and a second mounting groove 140, the first mounting groove 130 is an annular groove and is communicated with the side wall of the accommodating groove 10, the second mounting groove 140 is communicated with both ends of the first mounting groove 130, the first elastic part 410 is located in the first mounting groove 130, and the second elastic part 420 is located in the second mounting groove 140.

[0063] In the embodiment, since the first mounting groove 130 is communicated with the side wall of the accommodating groove 10, when the first elastic part 410 is located in the first mounting groove 130, it is equivalent to form an annular structure along the side wall of the accommodating groove 10, and at this time, it is stably fixed in the first mounting groove 130 to avoid shaking and slipping; the second mounting groove 140 can be used to accommodate the second elastic part 420 to avoid the second elastic part 420 from slipping.

[0064] Further, as shown in Figures 1 to 3 The side of the elastic part 400 towards the knob 100 is provided with a first guide inclined surface (not marked in the figure), the side wall of the first mounting groove 130 is provided with a second guide inclined surface 131, and the side wall of the second mounting groove 140 is provided with a third guide inclined surface 141, and the second guide inclined surface 131 and the third guide inclined surface 141 are both towards the rotating assembly.

[0065] The inclination angles of the second guide inclined surface 131 and the third guide inclined surface 141 are the same as the inclination angle of the first guide inclined surface, which are used to guide the first elastic part 410 and the second elastic part 420 to be inserted into the first mounting groove 130 and the second mounting groove 140 respectively.

[0066] In the embodiment, the second guide slope 131 and the third guide slope 141 are used to guide the elastic member 400 into the first mounting groove 130 and the second mounting groove 140, which can avoid the elastic member 400 from bumping against the groove of the first mounting groove 130 and the second mounting groove 140, and improve the assembly efficiency of the elastic member 400.

[0067] Correspondingly, the application also provides an atomization device, which comprises the knob 100 switch structure in any one of the above embodiments.

[0068] In the embodiment, the atomization device comprises the knob 100 switch structure in the above embodiment, so that the elastic member 400 can provide a resistance through its elastic deformation and / or friction, thereby allowing the user to feel the force that hinders the rotation of the knob 100, improving the feel of rotating the knob 100; at the same time, the user can also realize the rotation amplitude of the knob 100 without using the naked eye, improving the use efficiency of the knob 100 switch structure; then, because the elastic member 400 can provide a certain resistance, when the knob 100 has a rotation trend due to accidental touch, as long as the accidental touch force is less than the range of the resistance, the knob 100 can be prevented from being accidentally rotated. In summary, the atomization device of the embodiment can avoid accidental touch, has high use efficiency and good use feel.
