Air purifier and control method thereof

Wall-embedded air purifier with automatic air purification and lighting control via human motion detection

This technology discloses an air purifier and a control method that enables automatic air purification and indoor lighting. The invention features an air purification unit installed within a wall cavity, comprising a filter for purifying indoor air and a blower for forced air circulation. It also includes a lighting unit mounted in a separate compartment within the same wall cavity, featuring a light-emitting member and heat-dissipating fins that transfer heat from the light source to the air purification compartment. A motion sensor detects human presence and triggers the operation of both the air purification and lighting units, ensuring automated functionality.

Existing solutions in this field have faced structural and functional limitations that required improvement.

This technology can be applied to the relevant industry as an air purifier and control method to enhance performance and efficiency.
