Multi-protection dustproof mask

Abstract

The invention relates to the field of daily masks, in particular to a multi-protection dustproof mask. The mask comprises front and back symmetrical protective covers, a protective cavity with an opening in the right side is formed in each protective cover, the right side of each protective cover is connected with two symmetrical connecting cloth, the right sides of the connecting cloth are connected with cover plates, elastic cloth is connected between the front cover plate and the rear cover plate, a protection mechanism used for protecting eyes is arranged on the upper side of the protective cavity, an abutting mechanism used for abutting against the nose bridge and the sunken positions of the cheekbones is arranged on the right side of the protection mechanism, and two dustproof mechanisms which are symmetrical in the front-back direction are fixed to the inner wall of the left side of the protective cavity. The mask can perfectly fit the human face. Meanwhile, a filtering degree of a filtering component on the outermost side is adjustable, the non-woven fabric can be replaced every time the device is worn, the device can adapt to places with heavy dust, the eyes are protected through the protection mechanism, the non-woven fabric in the device is distributed in a W shape, an internal auxiliary mechanism can assist in breathing, and meanwhile, a silica gel filter screen can be cleaned.

Description

technical field [0001] The invention relates to the field of daily masks, in particular to a dustproof mask capable of multiple protections. Background technique [0002] In limestone processing factories, dust pollution will be very large. However, the existing dust-proof masks do not have enough blocking effect on dust, and this kind of masks are made of hard plastic. There are only sponges on the edges, which cannot Adapting to different people's face shapes will cause dust to pass through the mask, causing damage to people's health, and the mask only has a certain blocking effect on the mouth and nose, and has no protective effect on the face and eyes. The filter screen of the existing mask It's just a layer of cloth, the effect is extremely poor, and once it gets dirty, it needs to be disassembled and replaced, which is very inconvenient, and the degree of filtration is not adjustable. When used in an environment with little dust, it will feel like you can't breathe wel...
