AI Technical Summary
Technical Problem
In existing antipruritic devices, the microswitch has insufficient reset force and poor stability, the button is prone to misalignment when the spring is reset, and the limited internal space makes assembly troublesome.
Method used
The device employs a first and second arc-shaped spring on the button. The micro switch is triggered by the deformation when the button is pressed and released. It is assembled by plugging and connecting, and the circuit board and battery are staggered to avoid interference.
Benefits of technology
It provides a stable button reset force, simplifies the assembly process, improves the structural stability and ease of use of the antipruritic device, and avoids mutual interference between the battery and the circuit board.
