Detailed Description

Most of the existing breathing masks are of fixed structures, and filter elements or filter materials for filtering are arranged in or embedded in the breathing masks; at a certain time, built-in filter core or filtering material can't carry out filtering capability, and this moment because of the structure is fixed knot constructs, can't change filter core or filtering material, can only change whole respirator, and then lead to use cost to improve.

The inventor aims at the technical problem, and continuously researches and discovers a technical scheme of the breathing mask through analyzing reasons, wherein the technical scheme comprises a mask main body, a filter element and a cover body, wherein:

the filter element is arranged in the filter cavity.

In the technical scheme, the buckle with the openable cover body is arranged on the mask main body and covers the filter tank on the mask main body to form a filter cavity, the filter element is arranged in the filter cavity, and then when the filter element needs to be replaced, the cover body is only required to be opened and then buckled, so that the mask structure capable of replacing the filter element conveniently and rapidly is obtained, and the technical problem in the prior art is solved.

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

Example (b):

as shown in fig. 1 to 3, a technical solution of a breathing mask includes a mask body 1, a filter element 2 and a cover body 3.

Referring to fig. 1 to 5, the mask body 1 is a mask body capable of covering the mouth and nose of the face of a human body, a filtering tank 11 is disposed on the front side of the mask body, a one-way breathing valve body 4 is further disposed on the mask body 1, the number and position of the one-way breathing valve bodies 4 can be set according to specific requirements, and as an embodiment of the present invention, the number of the one-way breathing valve bodies 4 is two, and the two one-way breathing valve bodies 4 are disposed on two sides of the filtering tank 11 respectively;
