[0033] The following will be combined with Figures 1 to 7 to describe the key structure and itching reliever provided by the present utility model.

[0034] Refer to Figures 1 to 6 As shown, the key structure 10 provided by the embodiments of the present utility model includes: a pressing member 110, an indicating cover 120, and a control board 130.

[0035] The pressing member 110 includes a first main body portion 111 and a pressing portion 112, and the pressing portion 112 is provided on the inner surface of the first main body portion 111; the indicating cover 120 includes a second main body portion 121 and a conducting member 122, and a receiving cavity is formed in the second main body portion 121. The first main body portion 111 is slidably engaged with the inner wall of the second main body portion 121, and the pressing portion 112 is in abutting engagement with the conducting member 122; the control board 130 includes a third main body portion 131, a key module 132, and an indicator light module 133. The key module 132 and the indicator light module 133 are both provided on the third main body portion 131 and are located in the receiving cavity, and the conducting member 122 is in abutting engagement with the key module 132; the second main body portion 121 is made of a light-transmitting material, or a light-transmitting structure is provided on the second main body portion 121.

[0036] The key structure 10 provided by the present utility model saves the occupied space of the key structure 10 by multiplexing the functions of the key and the indicator light, simplifies the structure and the assembly process, facilitates the miniaturization of the device, and solves the defect in the existing itching reliever that the keys and the indicator lights are separately arranged, resulting in a relatively large occupied space and being unfavorable for the miniaturization of the device.

[0037] Specifically, the key structure 10 provided by the present utility model is provided with a pressing member 110, an indicating cover 120, and a control board 130. When in use, a pressing action is applied to the first main body portion 111, and the first main body portion 111 can drive the pressing portion 112 to slide along the depth direction of the accommodating cavity. The pressing portion 112 is in abutting and cooperating with the conducting member 122 to drive the conducting member 122 to trigger the key module 132 to generate a control signal. By making the second main body portion 121 of a light-transmitting material (or providing a light-transmitting structure on the second main body portion 121), the light generated by the indicator light module 133 can be observed through the indicating cover 120.

[0038] See Figures 2 to 4 As shown, the first main body portion 111 is a circular plate-shaped component, and a protrusion is provided at the center position of its inner surface, and this protrusion forms the above-mentioned pressing portion 112. The second main body portion 121 is a circular cylindrical component, and openings are provided at both ends of the second main body portion 121. The side wall of the circular plate-shaped first main body portion 111 is adapted to the inner wall of the circular cylindrical second main body portion 121, so that the first main body portion 111 can move along the axial direction of the second main body portion 121 ( Figure 1 the vertical direction shown), and drive the pressing portion 112 to move synchronously therewith. The third main body portion 131 is the main body of the control board 130.

[0039] In the initial state, the lower end surface of the pressing portion 112 abuts against the upper surface of the conducting member 122. When the first main body portion 111 is pressed, the pressing portion 112 can immediately drive the conducting member 122 to move and trigger the key module 132. This method enables the key module 132 to have a relatively fast response speed for triggering and can reduce the pressing stroke.

[0040] It should be noted that the above-mentioned "initial state" specifically refers to the initial state of the pressing member 110, the indicating cover 120, and the control board 130 when the pressing member 110 is not subjected to an external force (such as manual pressing by a user).

[0041] After the key module 132 is pressed by the pressing portion 112, it can generate a control signal, such as turning on or off the device, adjusting the operation mode or operation power of the device, etc.

[0042] The indicator light module 133 includes at least one indicator light. When the indicator light module 133 includes a single indicator light, the indicator light can emit indicator lights of different colors to prompt the current state of the user device. For example, when the indicator light emits a green indicator light, it indicates that the device is operating normally. When the indicator light emits a red indicator light, it indicates that the device is operating abnormally (such as device alarm, low device power). When the indicator light module 133 includes multiple indicator lights, the multiple indicator lights can surround the periphery of the button module 132.

[0043] In this embodiment, taking two as an example, one of the indicator lights can emit green indicator lights, and the other indicator light can emit red indicator lights. The lighting or extinguishing of the indicator lights of different colors represents different states. The red indicator light can represent an abnormal state, such as device alarm, low device power, etc.; the green indicator light can represent a normal working state when the device is powered on, and the green light goes out when the device is powered off.

[0044] In the indicator light module 133, the indicator lights emitted by the indicator lights can pass through the indicator cover 120 for the user to observe. When the indicator cover 120 is made of a light-transmitting material (such as translucent PC material), the indicator lights can directly pass through the side wall of the indicator cover 120; when the indicator cover 120 is provided with a light-transmitting structure (such as a light-transmitting opening made of a light-transmitting material, a hollowed light-transmitting observation window, etc.), the indicator lights can pass through the light-transmitting structure. Both of the above two methods can transmit the indicator lights emitted by the indicator lights to the outside, and the user can obtain the state of the device according to the different indicator lights emitted by the indicator lights.

[0045] See Figures 2 to 5 As shown, according to some embodiments of the present invention, the conducting member 122 includes a triggering portion 1221 and a plurality of elastic connecting pieces 1222. The plurality of elastic connecting pieces 1222 are circumferentially spaced apart on the triggering portion 1221, and the plurality of elastic connecting pieces 1222 are all connected to the inner wall of the second main body portion 121. By setting the conducting member 122 in the form of the triggering portion 1221 and the plurality of elastic connecting pieces 1222, when the user cancels the pressing action on the first main body portion 111, the plurality of elastic connecting pieces 1222 can make the triggering portion 1221 rebound and drive the pressing member 110 back to the initial position, realizing the automatic reset effect of the pressing member 110.

[0046] Specifically, a protrusion is provided on the side of the triggering portion 1221 facing the control board 130, and the protrusion abuts against the button module 132 on the control board 130. When the user presses the first main body portion 111, the pressing portion 112 drives the protrusion of the triggering portion 1221 to trigger the button module 132. When the user cancels the pressing action, the plurality of elastic connecting pieces 1222 can make the triggering portion 1221 rebound and drive the pressing member 110 back to the initial position. After the button module 132 loses the pressure of the protrusion, it can also return to the initial state.

[0047] See Figure 4 As shown, according to some embodiments of the present utility model, the conducting member 122 includes two elastic connecting pieces 1222, and the two elastic connecting pieces 1222 are symmetrically arranged at the trigger part 1221 in a central symmetry manner; the elastic connecting piece 1222 is an L-shaped elastic connecting piece, one end of the L-shaped elastic connecting piece is connected to the trigger part 1221, and the other end of the L-shaped elastic connecting piece is connected to the inner wall of the second main body part 121. Through the above arrangement, when no pressing action is applied to the pressing member 110, it can ensure that the trigger part 1221 is stably maintained in the initial state. In addition, when the user cancels the pressing action, the two L-shaped elastic connecting pieces can quickly make the trigger part 1221 rebound and drive the pressing member 110 to quickly return to the initial position.

[0048] See Figures 2 to 5 As shown, according to some embodiments of the present utility model, an axial limiting mechanism is provided between the pressing member 110 and the indicating cover 120, and the axial limiting mechanism includes a plurality of elastic buckles 113 and a clamping part 123; the plurality of elastic buckles 113 are arranged at intervals along the circumferential direction on the inner surface of the first main body part 111, and the clamping part 123 is arranged on the inner wall of the second main body part 121. In the initial state, the elastic buckles 113 are in clamping cooperation with the clamping part 123. By providing the axial limiting mechanism, when not in use or when the pressing action on the pressing member 110 is cancelled, the pressing member 110 can be stably maintained in the initial position to prevent it from coming out of the indicating cover 120.

[0049] Specifically, in this embodiment, an installation guiding inclined surface is provided on one side of the clamping part 123 facing the first main body part 111 and at the end of the elastic buckle 113. During installation, under the combined action of the two installation guiding inclined surfaces, the elastic buckle 113 elastically deforms radially inwards, and the pressing member 110 can be directly snapped into the indicating cover 120.

[0050] See Figure 1 As shown, according to some embodiments of the present utility model, there is a spacing between the connection position of the elastic buckle 113 and the first main body part 111 and the outer edge of the first main body part 111, and this spacing is greater than 2 mm, which can ensure the display effect of the indicator light module 133 and prevent the elastic buckle 113 from blocking the lamp tube of the indicator light.

[0051] See Figures 2 to 5 As shown, according to some embodiments of the present utility model, the clamping part 123 includes a plurality of clamping protrusions, the plurality of clamping protrusions are arranged at intervals along the circumferential direction on the inner wall of the second main body part 121, and the plurality of elastic buckles 113 are in one-to-one clamping cooperation with the plurality of clamping protrusions to axially limit the pressing member 110.

[0052] In some other embodiments, the clamping portion 123 is a flange, which is circumferentially arranged on the inner wall of the second main body portion 121, and a plurality of elastic buckles 113 are clamped and matched with the flange. In the initial state, the plurality of elastic buckles 113 can be clamped and matched with any position of the flange to axially limit the pressing member 110.

[0053] See Figure 1 As shown, according to some embodiments of the present invention, when the elastic buckle 113 is clamped and matched with the clamping portion 123 (in the initial state), the outer surface of the first main body portion 111 is flush with the end surface of the second main body portion 121. By making the outer surface of the first main body portion 111 flush with the end surface of the second main body portion 121 in the initial state, it is possible to prevent the outer surface of the first main body portion 111 from being concave or convex, improve the aesthetics of the button structure 10, and achieve a technical effect of preventing accidental touch to a certain extent.

[0054] See Figures 2 to 5 As shown, according to some embodiments of the present invention, a circumferential limiting mechanism is provided between the pressing member 110 and the indicating cover 120. The circumferential limiting mechanism includes a limiting block and a limiting groove. The limiting block is arranged on the inner surface of the first main body portion 111, and the limiting groove is arranged on the inner wall of the second main body portion 121. The limiting block is clamped and matched with the limiting groove. By providing the circumferential limiting mechanism, it is possible to prevent the pressing member 110 from rotating circumferentially when in the initial state or when being pressed, and improve the stability of the button structure 10.

[0055] See Figures 2 to 5 As shown, according to some embodiments of the present invention, the circumferential limiting mechanism includes a first limiting block 114, a second limiting block 115, a first limiting groove 124 and a second limiting groove 125. The first limiting block 114 and the second limiting block 115 have different shapes; the first limiting block 114 and the second limiting block 115 are oppositely arranged on both sides of the inner surface of the first main body portion 111, the first limiting groove 124 and the second limiting groove 125 are oppositely arranged on the inner wall of the second main body portion 121, the first limiting block 114 is clamped and matched with the first limiting groove 124, and the second limiting block 115 is clamped and matched with the second limiting groove 125. By providing the first limiting block 114, the second limiting block 115, the first limiting groove 124 and the second limiting groove 125, and the first limiting block 114 being clamped and matched with the first limiting groove 124 and the second limiting block 115 being clamped and matched with the second limiting groove 125, a stable circumferential limiting effect can be achieved on the pressing member 110. In addition, by setting the first limiting block 114 and the second limiting block 115 to have different shapes, a prompting effect can be achieved, which is convenient to distinguish the installation direction of the pressing portion 112 during installation and avoid installation errors.

[0056] Specifically, in this embodiment, two convex rib groups corresponding to the first limiting block 114 and the second limiting block 115 are provided on the inner wall of the indicating cover 120. The two convex rib groups are arranged at intervals in the circumferential direction. Each convex rib group includes two convex ribs arranged at intervals, and a limiting groove as described above is formed between the two convex ribs. The first limiting block 114 can be clamped between the two convex ribs of the corresponding convex rib group to achieve the circumferential limiting effect on the pressing member 110.

[0057] Referring to Figure 1 As shown, according to some embodiments of the present invention, a plurality of arc-shaped protrusions 126 are provided at intervals in the circumferential direction at one end of the second main body portion 121 close to the control board 130, and the plurality of arc-shaped protrusions 126 abut against the third main body portion 131. By providing a plurality of arc-shaped protrusions 126 at intervals in the circumferential direction at one end of the second main body portion 121 close to the control board 130, the plurality of arc-shaped protrusions 126 can abut against the third main body portion 131 to ensure the stability of the indicating cover 120 during use.

[0058] The operating principle of the key structure 10 provided by the present invention will be specifically described below. Referring to Figures 1 to 6 As shown.

[0059] During installation, the indicating cover 120 is fixed to the control board 130. The plurality of arc-shaped protrusions 126 provided at the lower end of the second main body portion 121 abut against the upper surface of the control board 130, and the triggering portion 1221 abuts against the upper surface of the key module 132. Subsequently, the pressing member 110 is placed in the indicating cover 120 to apply an axial pressing force to the first main body portion 111, so that the two elastic buckles 113 on the inner surface of the first main body portion 111 are in snap-fit with the engaging portion 123 provided on the inner wall of the second main body portion 121. At this time, the lower end surface of the pressing portion 112 abuts against the upper surface of the conductive member 122, and the first limiting block 114 and the second limiting block 115 are respectively in snap-fit with the first limiting groove 124 and the second limiting groove 125. The key structure 10 is in the initial state, and the outer surface of the first main body portion 111 is flush with the end surface of the second main body portion 121.

[0060] In use, the user applies a pressing force to the first main body portion 111. The first main body portion 111 can drive the pressing portion 112 to slide inward along the depth direction of the accommodating cavity. The pressing portion 112 is in abutting cooperation with the conduction member 122 and can drive the conduction member 122 to trigger the key module 132 to generate a control signal. By making the second main body portion 121 of a light-transmitting material (or providing a light-transmitting structure on the second main body portion 121), the light generated by the indicator light module 133 can be observed through the indicator cover 120. When the user withdraws the pressing force on the first main body portion 111, the plurality of elastic connecting pieces 1222 can cause the triggering portion 1221 to rebound and drive the pressing member 110 back to the initial position, making the outer surface of the first main body portion 111 flush with the end surface of the second main body portion 121. At the same time, after the key module 132 loses the pressure of the triggering portion 1221, it can also return to the initial state.

[0061] The antipruritic instrument provided by the present utility model will be described below. The antipruritic instrument described below can be correspondingly referred to the key structure 10 described above.
