Split portable circulating fluid film filter screen type respirator

Abstract

The invention discloses a split portable circulating fluid film filter screen type respirator. The split portable circulating fluid film filter screen type respirator comprises a mouth and nose shield, an oral cavity partition board, an air supply pipeline, an air filter box, an air storage cavity and a remote-control handle. A soft metal strip is arranged in a covered silicon edge of the mouth and nose shield. An exhaust valve is installed in an exhaust port. The air filter box can be fixed at the back or in front of the chest or on the waist through an elastic belt. Multiple filter screens are installed at an air inlet of the air filter box. A piece of circumferential ring filter cloth, a supporting roller, a tensioning roller, a folding roller, a fluid containing tank, a fluid regulating plate, an axial flow fan, a stepping motor, a rechargeable battery and a circuit board are arranged in a power cavity of the air filter box. The axial flow fan, the stepping motor and an electric heating net are all controlled through the remote-control handle. According to the split portable circulating fluid film filter screen type respirator, toxic and harmful solid and liquid particles larger than PM2.0 in the atmosphere can be filtered out, and germs and viruses can be killed through immersion liquid on the filter cloth; the electric heating net is installed in the air storage cavity, air is heated, and diseases of the respiratory tract of a wearer caused by the irritation of cold air are avoided during season changing. By the adoption of the split portable circulating fluid film filter screen type respirator, clean air is supplied into the mouth and nose shield, and the safety of the respiratory system of the wearer is guaranteed.

Description

technical field [0001] The invention belongs to a respiratory protective product, in particular to a split portable circulating liquid membrane filter type respirator. Background technique [0002] As we all know, the air pollution in China is very serious at present, and the health problems of the respiratory tract are also becoming more and more serious. PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, known as particulate matter that can enter the lungs. Toxic particles in the atmosphere of haze days——PM2.5 particles hinder normal blood circulation, leading to cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, can induce angina pectoris, myocardial infarction, heart failure, etc., and cause chronic bronchitis Cor pulmonale, etc. With the deterioration of air quality, the occurrence of hazy weather increases, the harmful effects are aggravated, chronic diseases are exacerbated, respira...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the appliance is relatively heavy and the structure is relatively complicated, especially the user needs to carry an air bag or a gas cylinder as an air source at the same time, the air supply time is short, and can only be used for 1 hour, and the price is relatively expensive, which is not conducive to ordinary Promoted use by family members

The disadvantage is that the host is heavy, the host must be in a safe working environment, the atmosphere around the host should meet the respiratory hygiene standards, and the user's range of activities can only be located within the radius of the air supply pipe, which is not conducive to remote use. The cost is high, which is not conducive to promoting the use of ordinary family members
