AI Technical Summary
Traditional car air purifiers with mechanical push-button switches are prone to frequent start-stop cycles due to vehicle bumps or accidental activation by objects, which can damage the lifespan of the fan.
The design employs a purely mechanical structure to prevent accidental activation. Through a miniature electric push rod and a linkage mechanism, the pressing block and the linkage hemisphere are engaged to form a safe distance and avoid accidental activation. The linkage block is designed to correspond to the pressing switch, and the linkage hemisphere is precisely embedded in the groove to trigger the start signal.
It effectively prevents accidental activation, extends the life of the fan, and the high-position operation of the mechanism prevents accidental triggering. The pressing block and the linkage hemisphere are an integral structure, which facilitates disassembly and replacement of worn parts.
