Mask

Abstract

The invention relates to a mask, which comprises a mask body, filter shells are arranged on the left side and the right side of the front side of the mask body, and filter mechanisms are movably connected to inner cavities of the filter shells. According to the invention, a filter screen, a protective shell, a filter mechanism and a limiting mechanism are matched for use; the limiting mechanism isused; the position of the protective shell can be fixed; the filter screen and the filter mechanism are used; impurities in the air can be filtered; the purity of the breathing air of the user is ensured; and the problems that the existing a dust-proof mask with a filter element usually adopts screw-tightening method during use, the sealing effect is low, the impurities in the air cannot be effectively filtered, and the phenomenon of repeated disassembly is easy to cause jamming are solved. The filter element for the mask and a convenient disassembly and replacement structure of the filter element have the advantages that the filter element is convenient to replace, the sealing effect is good, and the filter element for the mask is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of masks, in particular to a filter element for a mask and a convenient disassembly and replacement structure thereof. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper, etc. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. Masks can be divided into air filter masks and air supply masks. Face mask. [0003] With the emphasis on air quality and bacterial infection, various types of masks have been gradually developed. Dust masks with filter elements have been widely used in many industries because they c...
