Air filter for breathing and filter element thereof

Abstract

The invention relates to an air filter for breathing and a filter element thereof, belonging to the field of health protection. By adopting the bionic principle simulating the nasal cavity of human body, the filter element is formed by stacking a filtering layer and a liquid absorbing layer at intervals, and is positioned between an air inlet channel and an air outlet channel which are arranged inside a shell of a filtering component; and the liquid absorbing layer of the filter element extends into filtrate inside a liquid storage cavity, and the air outlet channel of the filtering component is connected with a breathing mask. The air filter has good filtering effect and convenient use, is suitable for staff working in the environment of dust, smoke and waste gas, and can be taken as fire control preparation article for standby application.

Description

technical field [0001] The invention belongs to the field of health protection, and in particular relates to a breathing air filtering device with a filtering element. Background technique [0002] With the rapid development of the economy, industrialization has degraded the air environment of people's work and life. In order to maintain human health, people wear medical masks and dust masks in environments with dust, smoke, exhaust gas and germs. To reduce the impact of harsh air environment on human breathing, medical masks and dust masks are more convenient to use and the price is also low. However, medical masks and dust masks are basically dry filtered by gauze, filter paper or non-woven fabric Air filtration has a limited protective effect, and it is difficult to truly protect the human body effectively. It also brings bad side effects such as inconvenience in language communication, unsmooth breathing, and facial discomfort. Especially with the further development of ...

[0002] With the rapid development of the economy, industrialization has degraded the air environment of people's work and life. In order to maintain human health, people wear medical masks and dust masks in environments with dust, smoke, exhaust gas and germs. To reduce the impact of harsh air environment on human breathing, medical masks and dust masks are more convenient to use and the price is also low. However, medical masks and dust masks are basically dry filtered by gauze, filter paper or non-woven fabric Air filtration has a limited protective effect, and it is difficult to truly protect the human body effectively. It also brings bad side effects such as inconvenience in language communication, unsmooth breathing, and facial discomfort. Especially with the further development of society, people on the road The rapid increase of vehicles, traffic police and sanitation workers and other special groups in the environment of vehicle exhaust and dust still lack truly applicable sanitary protective equipment, and some existing inventions and utility models cannot solve this problem well For example, the Chinese utility model patent "New Air Filter Mask" with the publication number CN2422980Y proposes a mask with wet sponge as the adsorption medium, but its filtering method for air is only to make the air flow through the surface of the wet sponge to absorb Part of the dust, the effect of filtering and purifying the air is not good enough, and the structure is more complicated, and it is not very convenient to use
