Air filtering device based on breathing

Abstract

The invention provides an air filtering device based on breathing, and relates to the technical field of breathing auxiliary equipment. The two ends of the air filtering shell are fixedly connected with fixing belts correspondingly. The filter plate contact cover is fixedly connected to the middle of an inner cover plate of the air filter shell; the outer air inlet end frame is fixedly connected to the inner side of a middle opening of an outer plate of the air filtering shell; the device is provided with the fixing assembly for continuously replacing the air filter element, the function of continuously replacing the air filter element is achieved, the probability of infection during replacement of the filter element or a mask is reduced, and the problem that for existing breathing filtering equipment, when the filter element or the mask of the filtering equipment is replaced, the mask needs to be taken off and then a new mask needs to be worn is solved. Viruses in the air can be easily removed from the face; and a novel filter cotton type mask needs to remove filter cotton and replace the filter cotton, and during the period, the interior of the mask is lack of protection of the filter cotton, so that viruses are organic and the infection probability is increased.

Description

technical field [0001] The invention relates to the technical field of breathing assistance equipment, in particular to an air filtering device based on breathing. Background technique [0002] In recent years, respiratory infectious diseases have spread in society, posing a great threat to people's health and freedom. Since respiratory viruses spread through the respiratory tract, masks can effectively block the spread of viruses. When moving in high-risk areas, due to The service life of the filter element of the mask is limited. The effective use time of ordinary medical shell masks is 4 hours, while the effective use time of ordinary KN95 masks is 8 hours. The wearer needs to replace the mask or replace the filter element in time to ensure that the mask has good filtration. Effect. [0003] However, as far as the current respiratory filtration equipment is concerned, when replacing the filter element of the filter equipment or changing the mask, it is necessary to take ...
