When the cleaning component 100 is in use, the control motor 107 drives the active gear 108 to rotate, and the active gear 108 is meshed with the driven gear 103a to drive the rotating ring 103 to rotate clockwise, so that the rotating ring 103 drives the rotating shaft 105a, the guide rod 105b and the arc scraper rod 104 to rotate, and the upper end of the guide rod 105b is blocked by the half circular groove of the special-shaped groove portion 106b, so that the guide rod 105b flips around the rotating shaft 105a. The arc scraper 104 also follows the guide rod 105b to flip over until the arc scraper 104 is perpendicular to the rotating ring 103 and is located outside the mirror cover 102. The rotating ring 103 continues to rotate, and the arc scraper 104 follows the rotating ring 103 to rotate circumferentially, and the mirror cover 102 is cleaned by the cotton strip 104a on the inside of the arc scraper 104.
