Description

Technical Field

[0001] This utility model relates to the field of antipruritic devices, and in particular to an antipruritic device. Background Technology

[0002] In existing technology, an anti-itch device includes a housing and an anti-itch head. The housing contains a battery and a heating element, which corresponds to the position of the anti-itch head. The operation of the heating element is controlled by a button switch. However, most button switches on the market currently use the reset force of a micro switch to reset the button, or use a spring to reset the button. If the reset is achieved solely by a micro switch, the reset force is insufficient and the stability is poor. If the reset is achieved by using a spring, the button can easily be pressed directly into the housing when the spring is misaligned. Furthermore, the internal space of the anti-itch device is limited, and the installation of the spring is also relatively troublesome. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides an anti-itch device. By setting two arc-shaped elastic sheets on the button, it can provide elastic restoring force to the button and is also more convenient to assemble.

[0004] This utility model discloses an antipruritic device, including a central frame. The central frame is equipped with a circuit board, a heating element, a micro switch, and a battery. The heating element, micro switch, and battery are all electrically connected to the circuit board. A first cover plate is provided on the front side of the central frame, covering the circuit board, heating element, and micro switch. A second cover plate is provided on the rear side of the central frame, covering the battery. A heat therapy head is provided on the central frame corresponding to the heating element, and a heat-conducting cover is provided on the heat therapy head. The device is characterized in that an operation port is provided on the first cover plate corresponding to the micro switch, and a button for triggering the micro switch is provided on the operation port. A first arc-shaped spring and a second arc-shaped spring are integrally formed or fixedly connected to the button. The first arc-shaped spring extends from the left side of the button around its outer periphery to the right side of the button and connects to the first cover plate. The second arc-shaped spring extends from the right side of the button around its outer periphery to the left side of the button and connects to the first cover plate, so that the first and second arc-shaped springs are connected end-to-end or close together.

[0005] Using the above technical solution, when the button is pressed, the first and second arc-shaped springs deform relative to each other under force, triggering the micro switch to work. When the button is released, the first and second arc-shaped springs reset, thereby driving the button to reset. During assembly, it is only necessary to connect the ends of the first and second arc-shaped springs to the first cover plate, and then place the first cover plate on the middle frame. The alignment is convenient, and the use of arc-shaped springs can provide sufficient deformation.

[0006] A further feature of this invention is that the front part of the middle frame is recessed to form a first assembly area, where the circuit board, micro switch, and heating element are all located. The rear part of the middle frame is recessed to form a second assembly area, where the battery is located. The first and second assembly areas are staggered in the vertical direction.

[0007] By adopting the above technical solution, this layout can separate the battery from the components on the circuit board to prevent them from interfering with each other, and will not touch other components when replacing the battery.

[0008] A further feature of this invention is as follows: a first mounting hole is provided at one end of the first arc-shaped spring sheet that mates with the first cover plate; a first shaft is provided on the first cover plate at the position corresponding to the first mounting hole; the first shaft is inserted into the first mounting hole and tightly fitted therewith; a second mounting hole is provided at one end of the second arc-shaped spring sheet that mates with the first cover plate; a second shaft is provided on the first cover plate at the position corresponding to the second mounting hole; the second shaft is inserted into the second mounting hole and tightly fitted therewith.

[0009] By adopting the above technical solution and using a plug-in assembly method, the button can be assembled onto the first cover plate first, and then the whole assembly can be carried out. The structural layout is reasonable, and the assembly process is simpler and more stable.

[0010] A further feature of this invention is that the heat therapy head has a constricted opening, with the smaller opening facing outwards.

[0011] By adopting the above technical solution, the heat-conducting cover can be protruded, making it more precise during heat application.

[0012] A further feature of this invention is that the middle frame is also equipped with a power switch for controlling the power supply of the circuit board.

[0013] By adopting the above technical solution, the product can be carried more safely by disconnecting the power supply. The power switch is preferably a toggle switch to prevent accidental contact while carrying the product. Attached Figure Description

A heat therapy head 8 is provided on the central frame 1 corresponding to the position of the heating element 3, and a heat-conducting cover 9 is provided on the heat therapy head 8. In this embodiment of the utility model, the first cover plate 6 corresponds to the position of the micro switch 4. An operation port 10 is provided, and a button 11 for triggering a micro switch 4 is provided on the operation port 10. A first arc-shaped spring 12 and a second arc-shaped spring 13 are integrally formed or fixedly connected to the button 11.
