AI Technical Summary
Existing dustproof testing devices for power tool switches suffer from problems such as large space occupation, high noise, poor reliability, lack of dust density data, and lack of monitoring of switch operating conditions.
The electrode plates, powered by batteries, generate an electromagnetic field to drive the movement of dust particles. The alternating operation of the electrode plates is controlled by a control board. Combined with dust monitoring sensors and a display panel, the dust density is monitored in real time. The clamping mechanism fixes the switch, simulating a dust environment.
It achieves dustproof testing with small footprint, low noise, and high reliability, and can monitor dust density and switching current in real time, thus improving the reliability and accuracy of the test.
