AI Technical Summary
Existing laser cleaning devices require an external air source, which limits their application scenarios. Furthermore, the small diameter of the external air pipe makes it difficult to effectively isolate dust, resulting in frequent replacement of protective lenses and high operating costs.
The laser cleaning device is equipped with a high-speed blower that blows out a high-speed airflow through the side air duct to block dust from entering and reduce lens contamination. It also monitors the lens status through a dispersive light and temperature protection switch to achieve self-cooling.
No external air source is required, effectively preventing dust from contaminating the lenses, extending lens life, reducing usage costs, and achieving self-cooling and easy operation.
