Mask based on ultraviolet and photocatalyst sterilization

Abstract

The invention discloses a mask based on ultraviolet and photocatalyst sterilization. The mask comprises a mask body, the mask body is sequentially provided with a plastic shell layer, an outer filtercotton layer, an inner filter cotton layer and an ergonomic support layer from outside to inside. The inner filter cotton layer is provided with a ventilation channel; a metal adsorption net and an ultraviolet light source are sequentially arranged in the ventilation channel from outside to inside; the inner filter cotton layer is provided with a photocatalyst film layer; photocatalyst particles are attached to the photocatalyst film layer through a spraying process, a transparent cover is arranged at the bottom end, right opposite to the photocatalyst film layer, of the inner filter cotton layer, a white light LED light source is arranged in the transparent cover, a battery is arranged at the bottom end of the plastic shell, and the ultraviolet light source and the white light LED light source are electrically connected with the battery. The mask based on ultraviolet and photocatalyst sterilization can filter pathogens such as bacteria and viruses in time, is used for guaranteeing cleanness and sanitation of breathing and playing a role in sterilization and deodorization, the ultraviolet light source effectively kills the pathogens, the sterilization effect is good, and meanwhilethe mask is comfortable to wear.

Description

technical field [0001] The invention relates to the field of masks, in particular to a mask based on ultraviolet and photocatalyst sterilization. Background technique [0002] A mask generally refers to a protective device worn on the mouth and nose to filter the air in the mouth and nose, so as to block harmful gases, odors, and droplets from entering and leaving the wearer's mouth and nose. Wearing a mask is to prevent viruses and bacteria from being transmitted to others and yourself. Wearing a mask in public is also a kind of courtesy and care for the people around you. In addition, masks are an important line of defense to prevent respiratory infectious diseases. Wearing masks can reduce the risk of respiratory virus infection. It can not only prevent patients from spraying droplets, reduce the amount and speed of spraying droplets, but also block the droplet nuclei containing bacteria and viruses. Prevent inhalation by wearer. When a large-scale respiratory infectiou...

Problems solved by technology

At present, ordinary masks are mostly made of gauze, non-woven fabrics, paper, etc. The basic function is to isolate dust, but the effect of preventing virus and bacterial infection is not good, and the effect of preventing infection is limited.

Of course, there are many types of masks for protection, disinfection, and
