External filtering protective mask

Abstract

An external filtering protective mask of the invention comprises a mouth-nose mask body and a filtering module. A mouth-nose cavity is formed in the mouth-nose mask body. The filtering module is detachably hung on the front outer side of the mouth-nose mask body, the filtering module is provided with a filtering cavity, and a filtering body is arranged in the filtering cavity. A communicating baseis arranged between the connecting parts of the mouth-nose cavity and the filtering cavity for communicating, and the communicating base is provided with a one-way valve. The filtering module and themouth-nose mask body are designed in an independent split manner, so that respective cleaning and disinfection can be carried out when the filtering module or the filtering body in the filtering module is replaced. Meanwhile, a certain gap exists between the filtering module and the mouth-nose mask body, so that the filtering module is far away from the mouth and the nose, the touch is prevented,the probability of contacting the mouth-nose mask body is reduced, and the novel coronavirus with super-strong transmission force is effectively prevented.

Description

technical field [0001] The invention relates to a mask, in particular to an external filtering protective mask. Background technique [0002] During the Spring Festival of 2020, the "new coronavirus" epidemic broke out. Because the "new coronavirus" has the characteristics of human-to-human transmission and rapid transmission, wearing a traditional N95 protective mask has a certain isolation effect, but it needs to be replaced after 4 hours of use. Disposable masks in the market are out of stock in large areas due to frequent replacement. Traditional N95 protective masks are made of integral filter cotton or non-woven fabric, and the filter material is relatively thick. Because the inner surface of the cover tightly fits the face, it will cause facial skin discomfort, unhygienic use and poor filtering effect. Masks are discarded after one-time use, which will cause waste and high cost of use. In addition, the electronic air-supply mask has a complex structure and high man...

[0002] During the Spring Festival of 2020, the "new coronavirus" epidemic broke out. Because the "new coronavirus" has the characteristics of human-to-human transmission and rapid transmission, wearing a traditional N95 protective mask has a certain isolation effect, but it needs to be replaced after 4 hours of use. Disposable masks in the market are out of stock due to frequent replacement

Because the inner surface of the cover tightly fits the face, it will cause facial skin discomfort, unhygienic use and poor filtering effect

Masks are discarded after one-time use, which will cause waste and high cost of use

In addition, the structure of the electronic air supply mask is complicated, and the manufacturing cost is relatively high

In the face of the "new coronavirus", the reusable fan cover cannot be effectively disinfected and cleaned

Because the filter body is a one-piece design structure built in the cover body, it is easy to touch the virus remaining on the surface of the cover body when the filter body can be replaced or cleaned, so it is not particularly suitable for the "new coronavirus" with super transmission power use
