Detailed Implementation

[0034] The technical solution of this utility model is described in detail below. Examples of the technical solution are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The technical solution described below with reference to the accompanying drawings is exemplary and is only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] Reference Figure 1 , 2As shown in Figure 3, the button structure provided in the first aspect embodiment of this utility model includes a support member 100, a slider 200, a first button 300, and a control component 400; the slider 200 is fixed to the support member 100 in a way that allows it to move back and forth; the first button 300, which can move up and down, can drive the slider 200 to move; the control component 400 includes a first adjustment switch 410 and a power switch 420, the first button 300 can be driven to touch the button 411 of the first adjustment switch 410, and the lever 421 of the power switch 420 is connected to the slider 200; the slider 200 can move between a first position and a second position; as shown in Figure 3. Figure 2 As shown, in the first position, the first button 300 is located directly above the button 411, and the slider 200 drives the lever 421 to move so that the power switch 420 is in the on state; as Figure 1 As shown, in the second position, the first button 300 is located on one side of the button 411, and the slider 200 drives the lever 421 to move so that the power switch 420 is in the off state.

[0039] By connecting the sliding member 200, which can move back and forth, to the lever 421 of the power switch 420, and by enabling the first button 300, which can move up and down, to drive the sliding member 200 to move, the first button 300 can press down the button 411 of the first adjustment switch 410 after the power switch 420 is in the on state. This allows the operator to trigger the adjustment switch by touching the power switch 420 with their finger without having to move to another position, making it convenient to use.

[0040] The operator drives the first button 300 to move, which in turn moves the slider 200, and simultaneously the slider 200 moves the lever 421 of the power switch 420; Figure 2 As shown, when the slider 200 moves from the second position to the first position, the power switch 420 switches from the off state to the on state, placing the first button 300 directly above the button 411 of the first adjustment switch 410. This allows the first button 300 to move downwards and touch the button 411 of the first adjustment switch 410, thereby triggering the first adjustment switch 410. Figure 1 As shown, when the slider 200 moves from the first position to the second position, the power switch 420 switches from the on state to the off state, so that the first button 300 is not directly above the button 411 of the first adjustment switch 410. Therefore, the first button 300 cannot touch the button 411 of the first adjustment switch 410 when it moves down, and thus the first adjustment switch 410 cannot be triggered.

[0041] It is understandable that the first button 300 being located to one side of the button 411 means that the first button 300 is offset from the position directly above the button 411.

[0042] Specifically, the button structure is installed on a handheld device, which can be a handheld device used in the field of hair dryers, or other handheld devices that can install button structures. Taking a handheld device used in the field of hair dryers as an example, the handheld device includes a fan and a heating element. The power switch 420 is used to start the fan and the heating element, and the first adjustment switch 410 is used to adjust the fan speed, adjust the temperature of the heating element, or provide one-button cold air. It is understood that the button structure can also be used in other fields.

[0043] Furthermore, such as Figure 3 , 4 As shown in Figure 5, the support member 100 includes:

[0044] Support part 110;

[0045] The deformable elastic part 120 is connected to the support part 110. The slider 200 is fixed on the elastic part 120 so that the slider 200 can move back and forth. The first button 300 is fixed on the elastic part 120 so that the first button 300 can move up and down.

[0046] The elastic part 120 is used in conjunction with the first button 300 and the slider 200 to simplify the overall structure and eliminate the need for a structure similar to a spring and guide groove.

[0047] During operation, the operator drives the first button 300 to move, which in turn moves the slider 200. The slider 200 causes the elastic part 120 to deform under force, allowing the slider 200 to slide back and forth relative to the support part 110. This allows the slider 200 to move the lever 421 back and forth, switching the state of the power switch 420. Additionally, the operator drives the first button 300 downward, causing the elastic part 120 to deform under force. This allows the first button 300 to move up and down relative to the support part 110, enabling the first button 300 to press the button 411.

[0048] Furthermore, such as Figure 5 , 6 As shown, the elastic part 120 includes:

[0049] Two connecting segments 121 are spaced apart in the left-right direction and connected to the support part 110;

[0050] The transition section 122 includes a first connecting block 1221 and two second connecting blocks 1222 spaced apart in the left and right directions. The left and right ends of the first connecting block 1221 are respectively fixedly connected to the ends of the two second connecting blocks 1222 away from the power switch 420 (the rear ends of the two second connecting blocks 1222). The two second connecting blocks 1222 are respectively connected to the two connecting sections 121. Both the first connecting block 1221 and the second connecting block 1222 can be driven to deform.

[0051] Mounting segment 123 is connected to two first connecting blocks 1221 and second connecting blocks 1222. Slider 200 and first button 300 are both mounted on mounting segment 123.

[0052] Since the first connecting block 1221 and the second connecting block 1222 on the outer side of the mounting section 123 can both deform, the first button 300 can drive the slider 200 to move back and forth, and the first button 300 can move up and down.

[0053] Understandably, in order to prevent the first button 300 from automatically resetting after moving the lever 421, the elastic part 120 or the transition section 122 is configured to prevent the first button 300 from automatically resetting after being moved.

[0054] The elastic part 120 adopts such a structure to make the structure of the support member 100 simple and facilitate the movement of the slider 200 and the first button 300. Furthermore, due to the elasticity of the elastic part 120, the sound of the button loosening when the handheld device is swung is solved.

[0055] Specifically, the first connecting block 1221 and the two second connecting blocks 1222 form a "U" shape. The shape of the vertical cross section of the second connecting block 1222 along the left and right direction is a wave shape that undulates up and down. The shape of the vertical cross section of the first connecting block 1221 along any part of its arc (the shape of the vertical cross section of the first connecting block 1221 along the left and right direction and the shape of the vertical cross section of the first connecting block 1221 along the front and back direction) is a wave shape that undulates up and down.

[0056] Furthermore, such as Figure 5 , 10 As shown, the shape of the first cross-section 1223 of the first connecting block 1221 in the front-back direction and the shape of the second cross-section 1224 of the second connecting block 1222 in the left-right direction are both wavy shapes that extend horizontally and undulate up and down. Due to the wavy shape, the thickness of the first connecting block 1221 in the front-back direction and the thickness of the second connecting block 1222 in the front-back direction at the wavy shape are both relatively thin, making it easier for the first connecting block 1221 and the second connecting block 1222 to deform in the front-back direction and up and down direction (the setting of the first connecting block 1221 makes it easier for the mounting section 123 to move back and forth, and the setting of the second connecting block 1222 makes it easier for the mounting section 123 to move up and down), so that the sliding member 200 and the first button 300 can be driven to move without much force.

[0057] Furthermore, such as Figure 1 , 7As shown, the control component 400 also includes a circuit board 430, which is located below the first button 300. The first adjustment switch 410 is mounted on the circuit board 430. The width of the circuit board 430 in the left-right direction is smaller than the width of the elastic part 120 in the left-right direction. The first button 300 is fixed to the top of the elastic part 120.

[0058] Since the width of the circuit board 430 in the left-right direction is smaller than the width of the elastic part 120 in the left-right direction, and the first button 300 is located on the top of the elastic part 120, when a hand with water droplets touches the first button 300, the water droplets will only drip onto the elastic part 120 and not onto the circuit board 430.

[0059] When the profile of the cross section of the first connecting block 1221 and the profile of the cross section of the second connecting block 1222 are both wavy, a drainage groove 1225 is formed on the upper part of the elastic part 120 outside the mounting section 123. When a hand with water droplets touches the first button 300, the water droplets will flow along the first button 300, then flow onto the elastic part 120, and then flow onto the drainage groove 1225, thereby preventing water droplets from dripping onto the first adjustment switch 410.

[0060] Specifically, such as Figure 5 As shown, the ends of the two second connecting blocks 1222 near the power switch 420 can be sealed or open. When sealed, the drain trough 1225 has a drain hole that drains water droplets to a place outside the circuit board 430. Alternatively, if water droplets do not flow to the circuit board 430, the drain hole can be omitted and the water can be collected directly. When open, the drain trough 1225 can drain water droplets to a place outside the circuit board 430.

[0061] Furthermore, such as Figure 1 As shown, the slider 200 has a through hole 201, a portion of the elastic part 120 is inserted into the through hole 201, and a first button 300 is mounted on the top of the portion of the elastic part 120 located in the through hole 201.

[0062] This is to ensure that when the first button 300 moves downward, it touches the button 411 of the first adjustment switch 410 through the elastic part 120, thus preventing the first button 300 from directly contacting the button 411. Also, the elasticity of the elastic part 120 prevents the first button 300 from shaking and producing abnormal noise.

[0063] Specifically, a portion of the mounting section 123 is inserted into the through hole 201.

[0064] Furthermore, such as Figure 8As shown, it also includes a second button 500, and the control component 400 also includes a second adjustment switch 440. The connecting section 121 has a mounting position 124 located on one side of the first button 300. The second button 500 is connected to the mounting position 124, and the second adjustment switch 440 is provided below the second button 500.

[0065] The second button 500 is fixed by the elastic part 120 to prevent abnormal noise when the second button 500 is shaken.

[0066] Specifically, the second regulating switch 440 is used to regulate the temperature of the heating element and the speed of the motor.

[0067] Specifically, mounting position 124 is connected to a fixing plate, and the second button 500 is mounted on the fixing plate.

[0068] Specifically, the second adjustment switch 440 is mounted on the circuit board 430.

[0069] Furthermore, such as Figure 8 As shown, the shape of the first part 125 of the elastic part 120 in front of the second button 500 and the shape of the second part 126 of the elastic part 120 behind the second button 500 are both wavy shapes that extend in the front-back direction and undulate up and down, so as to facilitate the second button 500 to move down and press the second adjustment switch 440.

[0070] Furthermore, the sliding member 200 and the elastic part 120 are integrally formed so that the sliding member 200 and the support member 100 are integrated, which facilitates installation.

[0071] The handheld device provided in the second aspect embodiment of this utility model, such as Figure 9 As shown, the first aspect embodiment includes a button structure and a housing 600. The side wall of the housing 600 has a mounting hole 610. The support member 100 is installed inside the housing 600. The slider 200 and the control component 400 are both located inside the housing 600. A portion of the first button 300 extends out of the housing 600 through the mounting hole 610 and can move back and forth within the mounting hole 610.

[0072] By incorporating the button structure of the first aspect embodiment, it is more convenient for users to use handheld devices.

[0073] Specifically, the handheld device also includes an inner shell located inside the outer shell 600, on which the support 100 and circuit board 430 are mounted.

[0074] Specifically, the second button 500 can also extend out of the outer casing 600.
