Description

Mask with ozone protection function

Technical Field

The utility model relates to the field of protective articles, in particular to a mask with an ozone protection function.

Background

Ozone is a strong oxidant and is widely used in sewage treatment, reclaimed water reuse, purified water treatment, food processing, medical production, chemical oxidation, medical and health, water works, hospitals, factories, living communities, swimming pools, beverage and food, pharmaceutical factories, self-contained wells, water storage tanks, water tanks, livestock and aquaculture, refrigeration houses, landscape water and other fields such as water quality disinfection, waste gas treatment, ozone oxidation, air sterilization and the like.

The current application of ozone disinfection is very wide, a small amount of low-concentration ozone is harmless to human body, however, ozone with higher concentration can cause harm to human body. For example, when the concentration of ozone in the atmosphere reaches 0.1 milligrams per cubic meter, ozone can cause irritation to the mucous membranes of the nose and throat of a person. When the ozone concentration reaches 0.1 to 0.2 mg per cubic meter, the upper respiratory tract of a person is damaged, upper respiratory tract diseases are caused, even asthma attacks are caused, and eyes feel irritation. When the ozone concentration reaches more than 2 milligrams per cubic meter, headache and chest pain can be caused. In severe cases, pulmonary edema may result. Ozone exceeding standard has erosion and damage effects on human body, especially on eyes, respiratory tract, etc. Thus, too high an ozone concentration can cause significant irreversible damage to the human body.
