Medical mask comprising nanoscale photocatalyst functional layer

Abstract

The invention relates to a medical mask comprising a nanoscale photocatalyst functional layer. The medical mask comprises an upper cotton yarn layer and a lower cotton yarn layer, wherein an accommodation cavity is formed between the upper cotton yarn layer and the lower cotton yarn layer; a sterilization layer is placed in the accommodation cavity; and photocatalyst nano powder for sterilizationis wrapped in the sterilization layer. The medical mask comprises the upper cotton yarn layer and the lower cotton yarn layer; the accommodation cavity is formed between the upper cotton yarn layer and the lower cotton yarn layer; the photocatalyst nano powder is placed in the accommodation cavity; since adhesive layers are arranged on the sides, facing towards the accommodation cavity, of the upper cotton yarn layer and the lower cotton yarn layer; and the accommodation cavity is filled with the photocatalyst nano powder.

Description

technical field [0001] The invention relates to a medical mask, in particular to a medical mask containing a nanoscale photocatalyst functional layer. Background technique [0002] At present, the mouthpiece of the domestic prior art is made of non-woven fabric or cotton yarn fabric. The purpose of wearing it is to prevent harmful gases and substances such as bacteria, viruses, large particles of dust, and odor from being sucked into the human body, but there is no Anti-inflammatory, bactericidal, and sterilizing effects. [0003] As disclosed in the Chinese patent with the application publication number "CN104957806A", a reusable photocatalyst medical protective mask for sterilization, antivirus and odor removal is provided with a supercritical nanoscale photocatalyst coating on the outer surface of the non-woven fabric or cotton fabric layer. Layer, the upper and lower ends of the non-woven fabric or cotton fabric layer of the photocatalyst mask are provided with a skelet...

Problems solved by technology

[0003] As disclosed in the Chinese patent with the application publication number "CN104957806A", a reusable photocatalyst medical protective mask for sterilization, antivirus and odor removal is provided with a supercritical nanoscale photocatalyst coating on the outer surface of the non-woven fabric or cotton fabric layer. Layer, the upper and lower ends of the non-woven fabric or cotton fabric layer of the photocatalyst mask are provided with a skeleton, so as to effectively kill bacteria, viruses, remove odors, prevent pollen, dust, air-conditioning allergies, and inhibit infectious viruses; With the advancement of domestic technology in recent years, there are more and more medical protective masks with bactericidal properties, but after long-term use, the photocatalyst activity in them decreases, which affects the killing rate of bacteria, viruses, etc.
