Routine maintenance
　　1. Pay attention to anti-collision when using the nozzle, and prevent falling after use. Even if the air nozzle is fixed, pay attention to prevent objects from colliding.
　　2. When cleaning the ion probe and the ion probe chamber of the air nozzle, use absolute alcohol instead of water. When cleaning, first cut off the power, then unscrew the small plastic cover (also known as the air accelerator) in front of the air nozzle with the camera, clean the ion probe and the inner cavity of the ion probe chamber with a cotton swab dipped with anhydrous alcohol, and clean the internal stains and dirt inside.
　　3. Timely cleaning and maintenance can improve the use effect and prolong the service life.
