AI Technical Summary
The fingerprint panels of existing fingerprint locks are prone to getting dirty with dust, oil, water, and other grime, which affects recognition accuracy and lifespan. Furthermore, cleaning them is inconvenient for users and the effectiveness is difficult to guarantee.
A protective cleaning component was designed, including a fixed sleeve and a rotating sleeve. The rotating sleeve is embedded with a deformation pad, a scraper sleeve, and a cleaning sponge pad. Automatic cleaning and protection of the fingerprint panel is achieved through a staggered sliding groove to prevent contamination.
It achieves efficient cleaning of the fingerprint panel, protects the panel from wear and tear, extends its service life, ensures stable operation of the recognition function, and adapts to different usage scenarios.
