If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] Reference Figure 1 , 2 As shown in , 3, the key structure provided by the embodiment of the first aspect of the present invention includes a support member 100, a sliding member 200, a first key 300 and a control component 400; the sliding member 200 is fixed on the support member 100 so as to be movable forward and backward; the first key 300 which can be movable up and down can drive the sliding member 200 to move; the control component 400 includes a first regulating switch 410 and a power switch 420, the first key 300 can be driven to touch the button 411 of the first regulating switch 410, and the lever 421 of the power switch 420 is connected to the sliding member 200; the sliding member 200 can move between a first position and a second position; as shown in Figure 2 As shown, in the first position, the first button 300 is located directly above the button 411, and the sliding member 200 drives the lever 421 to move so that the power switch 420 is in the on state; Figure 1 As shown, in the second position, the first button 300 is located on one side of the button 411, and the sliding member 200 drives the lever 421 to move so that the power switch 420 is in the off state.

[0024] By connecting the sliding member 200 that can move forward and backward with the lever 421 of the power switch 420, and enabling the first button 300 that can move up and down to drive the sliding member 200 to move, and then the first button 300 drives the sliding member 200 to move, after the power switch 420 is in the on state, the first button 300 can press down the button 411 of the first adjustment switch 410, so that after the operator's finger triggers the power switch 420, the adjustment switch can be triggered without moving to other positions, which is easy to use.

[0025] The operator drives the first button 300 to move, the first button 300 drives the sliding member 200 to move, and the sliding member 200 drives the lever 421 of the power switch 420 to move; Figure 2 As shown, when the sliding member 200 moves from the second position to the first position, the power switch 420 is switched from the off state to the on state, so that the first button 300 is located directly above the button 411 of the first adjustment switch 410, and then the first button 300 can move downward and touch the button 411 of the first adjustment switch 410, thereby triggering the first adjustment switch 410; Figure 1 As shown, when the sliding member 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 located directly above the button 411 of the first adjustment switch 410, and then the first button 300 cannot touch the button 411 of the first adjustment switch 410 when moving downward, thereby failing to trigger the first adjustment switch 410.

[0026] It can be understood that the first button 300 being located at one side of the button 411 means that the first button 300 deviates from a position directly above the button 411 .

[0027] 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 be equipped with a button structure. Taking the handheld device used in the field of hair dryers as an example, the handheld device includes a fan and a heating component, the power switch 420 is used to start the fan and the heating component, and the first adjustment switch 410 is used to adjust the fan speed, adjust the temperature of the heating component or one-button cold air. It can be understood that the button structure can also be used in other fields.

[0028] Furthermore, if Figure 3 , 4 As shown in FIG. 5 , the support member 100 includes: Supporting portion 110; The deformable elastic part 120 is connected to the supporting part 110 , the sliding member 200 is fixed on the elastic part 120 so that the sliding member 200 can move forward and backward, and the first button 300 is fixed on the elastic part 120 so that the first button 300 can move up and down.

[0029] The elastic part 120 is used in conjunction with the first button 300 and the sliding member 200 to simplify the entire structure without the need to design structures such as springs and guide grooves.

[0030] During operation, the operator drives the first button 300 to move, and the first button 300 drives the sliding member 200 to move. The sliding member 200 causes the elastic part 120 to be deformed by force, and then the sliding member 200 can slide back and forth relative to the support part 110, so that the sliding member 200 can drive the lever 421 to move back and forth to achieve the switching of the power switch 420 state, and the operator drives the first button 300 to move downward, and the first button 300 causes the elastic part 120 to be deformed by force, and then the first button 300 can move up and down relative to the support part 110, so that the first button 300 can press the button 411.

[0031] Furthermore, if Figure 5 , 6 As shown, the elastic portion 120 includes: Two connecting sections 121 are spaced apart in the left-right direction and connected to the supporting portion 110; The transition section 122 includes a first connection block 1221 and two second connection blocks 1222 spaced apart from each other in the left and right directions. The left and right ends of the first connection block 1221 are respectively fixedly connected to one end of the two second connection blocks 1222 away from the power switch 420 (the rear ends of the two second connection blocks 1222). The two second connection blocks 1222 are respectively connected to the two connection sections 121. Both the first connection block 1221 and the second connection block 1222 can be driven to deform. The mounting section 123 is connected to the two first connecting blocks 1221 and the second connecting block 1222 . The sliding member 200 and the first button 300 are both mounted on the mounting section 123 .

[0032] Since the first connection block 1221 and the second connection block 1222 outside the installation section 123 can be deformed, the first button 300 can drive the sliding member 200 to move forward and backward, and the first button 300 can move up and down.

[0033] It is understandable that in order to prevent the first button 300 from automatically resetting after the lever 421 is moved, the elastic force of the elastic portion 120 or the transition section 122 is configured to prevent the first button 300 from automatically resetting after being moved.

[0034] The elastic part 120 adopts such a structure to simplify the structure of the support member 100 and facilitate the movement of the sliding member 200 and the first button 300. Due to the elasticity of the elastic part 120, the sound of the button loosening when the handheld device is swung is solved.

[0035] Specifically, the first connecting block 1221 and the two second connecting blocks 1222 form a "U" shape, and the shape of the vertical section of the second connecting block 1222 along the left-right direction is a wave shape that undulates up and down, and the shape of the vertical section of the first connecting block 1221 along any point of its arc (the shape of the vertical section of the first connecting block 1221 along the left-right direction and the shape of the vertical section of the first connecting block 1221 along the front-back direction) is a wave shape that undulates up and down.

[0036] Furthermore, if Figure 5 , 10 As shown, the shape of the first cross section 1223 of the first connection block 1221 in the front-to-back direction and the shape of the second cross section 1224 of the second connection block 1222 in the left-to-right direction are both wavy shapes extending in the horizontal direction and undulating up and down. Due to the wavy shape, the thickness of the first connection block 1221 in the up-to-down direction at the wavy part and the thickness of the second connection block 1222 in the up-to-down direction at the wavy part are both thinner, making it easier for the first connection block 1221 and the second connection block 1222 to deform in the front-to-back direction and the up-to-down direction (the setting of the first connection block 1221 makes it easier for the installation section 123 to move forward and backward, and the setting of the second connection block 1222 makes it easier for the installation section 123 to move up and down), and the sliding member 200 and the first button 300 can be driven to move without a large force.

[0037] Furthermore, if Figure 1 , 7 As 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 installed on the circuit board 430. The width of the circuit board 430 in the left and right directions is smaller than the width of the elastic part 120 in the left and right directions. The first button 300 is fixed to the top of the elastic part 120.

[0038] 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.

[0039] When the cross-sectional profile of the first connecting block 1221 and the cross-sectional profile of the second connecting block 1222 are both wavy, a drainage groove 1225 is formed at the portion of the upper end of the elastic portion 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 portion 120, and then flow onto the drainage groove 1225, thereby preventing the water droplets from dripping onto the first adjustment switch 410.

[0040] Specifically, Figure 5As shown, one end of the two second connecting blocks 1222 close to the power switch 420 can be sealed or open. When sealed, the drainage groove 1225 has a drainage hole, which drains water droplets to a place outside the circuit board 430. Alternatively, the drainage hole can be omitted while ensuring that the water droplets do not flow to the circuit board 430, and the water can be directly collected. When open, the drainage groove 1225 can drain the water droplets to a place outside the circuit board 430.

[0041] Furthermore, if Figure 1 As shown, the sliding member 200 has a through hole 201 , a portion of the elastic portion 120 is inserted into the through hole 201 , and a first button 300 is installed on the top of the portion of the elastic portion 120 located in the through hole 201 .

[0042] When the first button 300 moves downward, the elastic part 120 touches the button 411 of the first adjustment switch 410 to prevent the first button 300 from directly contacting the button 411 . The elasticity of the elastic part 120 also prevents the first button 300 from shaking and making abnormal noises.

[0043] Specifically, a portion of the mounting section 123 is inserted into the through hole 201 .

[0044] Furthermore, if Figure 8 As 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 arranged below the second button 500.

[0045] The second button 500 is fixed by the elastic portion 120 to prevent the second button 500 from making abnormal noise when shaking.

[0046] Specifically, the second regulating switch 440 is used to adjust the temperature of the heating component and the speed of the motor.

[0047] Specifically, the mounting position 124 is connected to a fixing plate, and the second button 500 is mounted on the fixing plate.

[0048] Specifically, the second regulating switch 440 is mounted on the circuit board 430 .

[0049] Furthermore, if Figure 8 As shown, the shape of the first part 125 of the elastic part 120 located in front of the second button 500 and the shape of the second part 126 of the elastic part 120 located behind the second button 500 are both extended in the front-to-back direction and are in a wave shape that undulates up and down, so as to facilitate the second button 500 to move downward and press the second adjustment switch 440.

[0050] Furthermore, the sliding member 200 and the elastic portion 120 are integrally formed so that the sliding member 200 and the supporting member 100 are integrated to facilitate installation.

[0051] The handheld device provided by the second embodiment of the present invention is as follows: Fig. 9 As shown, it includes a button structure and a shell 600 of the first aspect embodiment, the side wall of the shell 600 has a mounting hole 610, the support member 100 is installed in the shell 600, the sliding member 200 and the control component 400 are both located in the shell 600, and a portion of the first button 300 extends out of the shell 600 through the mounting hole 610 and can move back and forth in the mounting hole 610.

[0052] By providing the key structure of the first embodiment, it is more convenient for the user to use the handheld device.

[0053] Specifically, the handheld device further includes an inner shell, which is located inside the outer shell 600 , and the support member 100 and the circuit board 430 are both mounted on the inner shell.

[0054] Specifically, the second button 500 may also extend out of the housing 600 .
