Air purifier with integrated light source and guide
The granted patent US12044429B2 describes an innovative air purifier design that integrates advanced light-guiding technology to enhance its functionality. The air purifier consists of a first body with an inlet and outlet, housing a fan, and a second body that extends radially outward. Central to its design is a light source connected to a substrate within the second body, which generates light. An inner light guide is strategically positioned to receive and direct this light from the source to the lower wall of the second body, ensuring effective illumination. The inner light guide features a light receiving region, a light channel, and a light emitting region, which collectively facilitate the transmission of light outward.
Additionally, the patent outlines the inclusion of an outer light guide that receives light from the inner light guide and emits it externally. This outer light guide is designed to be detachably coupled to the second body and can be positioned at varying distances from the outer wall of the first body. The design allows for multiple light sources and light receiving protrusions, enhancing the air purifier's aesthetic and functional appeal. The claims also detail various configurations of the light guides, including curved extensions and specific alignments with the substrate, which contribute to the overall efficiency and effectiveness of the air purification process.
