[0036] Various embodiments of the present application can exist in the form of a range; it should be understood that the description in the form of a range is only for the convenience and brevity, and should not be understood as a hard limit on 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., as well as single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. In addition, whenever a numerical range is indicated in the present application, it refers to any cited number (fraction or integer) within the indicated range.

[0037] Please refer to Figures 1 to 3 The embodiment of the present application provides a knob switch structure, which comprises:

[0038] The knob 100 is provided with a containing groove 10, and the groove bottom of the containing groove 10 is provided with an abutting portion 110;

[0039] The rotating piece 200 is located in the containing groove 10 and is rotationally connected to the knob 100;

[0040] The detection assembly 300 comprises a main body 320 and a detection part 310 connected with each other, the main body 320 is connected with the rotating part 200, and at least part of the detection part 310 is located in the accommodating groove 10.

[0041] The detection part 310 moves in the accommodating groove 10 along the rotating path 30, and the abutting part 110 is located on the rotating path 30 and used for abutting against the detection part 310.

[0042] In the embodiment, since the rotating part 200 is rotationally connected with the knob 100, and the main body 320 is connected with the rotating part 200, when it is needed to start the knob switch structure, 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 part 310 changes, which can be regarded as that the detection part 310 moves along the rotating path 30. Since the abutting part 110 is located on the rotating path 30, the detection part 310 will contact the abutting part 110 (as shown in FIG. 4) after moving a certain distance. After the detection part 310 contacts the abutting part 110, the main body 320 will sense that the detection part 310 is abutted, and then a starting signal is triggered to start the knob switch structure. When it is needed to close the knob switch structure, the knob 100 can be driven to rotate along the rotating path 30, at this time, the detection part 310 will be separated from the abutting part 110 (as shown in FIG. 5). After the main body 320 senses that the detection part 310 is separated from the abutting part 110, a closing signal can be triggered to close the knob switch structure. Figure 2 Figure 3 Figure 4

[0043] In summary, the knob switch structure of the embodiment of the present application can start or close the switch by rotating the knob 100, and has simple structure and is not easy to be mistakenly touched or started by children, so that the function of avoiding mistaken touch and child lock can be achieved. It should be understood that the main body 320 can sense the detection part 310 in the following ways: sensing whether the detection part 310 is retracted (the detection part 310 will move towards the main body 320 after being abutted by the abutting part 110), sensing whether the detection part 310 is deformed, or sensing the resistance change of the detection part 310 through a strain gauge or the like. The starting signal can be triggered when the detection part 310 is abutted by the abutting part 110, or can be triggered when the detection part 310 is separated from the abutting part 110. The main body 320 can be arranged in the rotating part 200, and the detection part 310 is connected with the main body 320 and located on the side of the main body 320 facing the bottom of the accommodating groove 10, so that the detection part 310 is located in the accommodating groove 10.

[0044] Further, please refer to Figures 1 to 2 and Figure 5 ​​​The knob 100 switch further comprises a limiting member 400 connected to the bottom of the accommodating groove 10. The side of the rotating member 200 facing the accommodating groove 10 is provided with a limiting through hole 210, and the end of the limiting member 400 facing the rotating member 200 is clamped in the limiting through hole 210, for limiting the rotation angle of the knob 100 relative to the rotating member 200.

[0045] In the embodiment, since the limiting member 400 is connected to the bottom of the accommodating groove 10, and the limiting through hole 210 is located on the rotating member 200, when the rotating member 200 rotates relative to the knob 100, the limiting member 400 also rotates relative to the limiting through hole 210. When the limiting member 400 is clamped in the limiting through hole 210, the limiting member 400 will be limited, so that the user knows that the atomization device has been opened / closed, or the user feels that it has rotated to a certain extent and needs to change the rotation direction.

[0046] It should be understood that the limiting member 400 can be a combination of a spring and a ball, wherein the spring is connected to the ball and the bottom of the accommodating groove 10, for driving the ball to move towards the rotating member 200. The ball can relatively move with the rotating member 200 through rolling friction until the ball rolls into the limiting through hole 210.

[0047] Further, referring to Figures 1 to 2 and Figure 5 , the limiting through hole 210 comprises a first limiting through hole 211 and a second limiting through hole 212. When the detection part 310 abuts against the abutting part 110, the limiting member 400 is located in the first limiting through hole 211, and when the detection part 310 is separated from the abutting part 110, the limiting member 400 is located in the second limiting through hole 212.

[0048] In the embodiment, when the limiting member 400 is located in the first limiting through hole 211, the detection part 310 abuts against the abutting part 110, so that the user can obviously feel the resistance when rotating the knob 100 to the detection part 310 abutting against the abutting part 110. In summary, the combination of the first limiting through hole 211 and the second limiting through hole 212 can enable the user to clearly determine the current state of the atomization device by the resistance felt by the hand when rotating the knob 100, and also can avoid the user from rotating the knob 100 beyond the stroke.

[0049] Further, referring to Figure 1 and Figure 2 , the end of the limiting member 400 facing the limiting through hole 210 is provided with a limiting surface 410, the limiting surface 410 is a curved surface, and abuts against the inner wall of the limiting through hole 210.

[0050] In the embodiment, when the limiting surface 410 is a curved surface, the contact area between the limiting member 400 and the rotating member 200 before the limiting member 400 enters the limiting through hole 210 can be effectively reduced, and the friction between the rotating member 200 and the limiting member 400 is reduced, so that the user can rotate the knob 100.

[0051] Further, referring to Figures 1 to 4 , the knob switch structure further comprises an elastic member 500, which is located between the rotating member 200 and the knob 100 and is in interference fit with the knob 100 and the rotating member 200.

[0052] In the embodiment, because the elastic member 500 is located between the rotating member 200 and the knob 100 and is in interference fit with the knob 100 and the rotating member 200, when the user drives the knob 100 to rotate relative to the rotating member 200, the elastic member 500 will provide a certain friction, so that the user can clearly feel the hand feeling of opening / closing the knob switch structure.

[0053] Further, referring to Figures 2 to 4 , the side of the abutting portion 110 facing the detection portion 310 is provided with at least two steps 111, the side of the abutting portion 110 facing the knob 100 is provided with an abutting surface 112, and the steps 111 connect the groove bottom of the accommodating groove 10 and the abutting surface 112.

[0054] In the embodiment, the steps 111 can allow the detection portion 310 to be abutted by the abutting portion 110 in a gradient manner, thereby improving the hand feeling feedback of the user; at the same time, the steps 111 can make the shear force received by the detection portion 310 uniform, avoid the shear force received by the detection portion 310 from being too large at a moment to cause the detection portion 310 to break, and thereby improve the service life of the knob 100 switch.

[0055] Further, referring to Figure 1 , the knob 100 switch further comprises a fixing member 600 and a screw 700, the fixing member 600 is provided with a positioning through hole 610 and is located on the side of the knob 100 away from the rotating member 200, the rotating member 200 is provided with a positioning protrusion 220 on the side facing the knob 100,

[0056] The positioning protrusion 220 is arranged in the positioning through hole 610, the screw 700 is arranged in the fixing member 600 and is in threaded connection with the rotating member 200, and the head of the screw 700 abuts against the side of the fixing member 600 away from the knob 100.

[0057] In the embodiment, the connection combination of the fixing member 600 and the rotating member 200 can clamp the knob 100 therebetween without affecting the rotation of the knob 100.

[0058] Further, referring to Figures 1 to 5The bottom of the accommodating groove 10 is provided with a detection groove 20, and the abutting portion 110 and the partial detection portion 310 are located in the detection groove 20; and / or,

[0059] The positioning through hole 610 is an arc-shaped hole, and the positioning protrusion 220 is sized and shaped to fit the arc-shaped hole; and / or,

[0060] The outer side wall of the knob 100 is provided with an anti-skid protrusion 101.

[0061] In the embodiment, the detection groove 20 can be used for the movement of the detection portion 310, and the side wall of the detection groove 20 can block the detection portion 310 from moving beyond the preset range of the movement path. When the positioning through hole 610 is an arc-shaped hole, the structural strength of the positioning protrusion 220 can be effectively improved, and the positioning protrusion 220 can prevent mistakes and improve the structural stability between the fixing member 600 and the rotating member 200. When the outer side wall of the knob 100 is provided with the anti-skid protrusion 101, the anti-skid protrusion 101 can increase the friction when the user rotates the knob 100, thereby avoiding slipping and improving the use efficiency of the knob 100 switch device.

[0062] Correspondingly, please refer to Figures 1 to 5 The application also provides an atomization device, which comprises the knob switch structure in any of the above embodiments.

[0063] In the embodiment, when the knob switch structure needs to be started, the knob 100 can be driven to rotate in the opposite direction of the rotating path 30. At this time, the detection portion 310 moves along the rotating path 30 and contacts the abutting portion 110 located on the rotating path 30 after moving a certain distance. After the detection portion 310 contacts the abutting portion 110, the main body 320 will sense that the detection portion 310 is abutted, and then trigger a start / stop signal to start / stop the atomization device of the knob 100.

[0064] In summary, the atomization device of the embodiment can be started or stopped by rotating the knob 100, and the structure is simple and not easy to be mistakenly touched or started by children, so that the function of avoiding mistaken touch and child lock can be achieved.
