Air purification mask

Abstract

The present invention provides a mask. The mask includes a mask body, a filter module installed on the mask body, a light source and a photocatalyst plate. The filter module includes a cavity, and it is provided with an air inlet and an air outlet which are located in different regions of the filter module. The photocatalyst plate and the light source are both located in the cavity. The surface of the photocatalyst plate is covered with a photocatalyst coating, and the light emitted by the light source irradiates the photocatalyst plate. In the embodiment of the present invention, by placing the light source and the photocatalyst plate in the cavity of the filter module, the photocatalyst generates strong oxidizing substances under light irradiation, which substances can inactivate harmful substances. Therefore, by placing the light source and the photocatalyst plate in the cavity of the filter module, harmful substances entering the mask can be sterilized and inactivated. The harmful substances after the sterilization and inactivation are no longer harmful, so there is no secondary pollution caused by harmful substances dropping off. It solves the problem of secondary pollution caused by the harmful substances in existing masks.
