Abstract

The invention belongs to the field of personal protection devices, and provides an anti-dust gauze mask. The anti-dust gauze mask comprises a gauze mask main body, wherein two jacket layers, which are represented as sheet-shaped structures, are arranged at the inner side of the gauze mask main body; the two jacket layers are arranged on wing parts at two sides of the gauze mask main body; and accommodating openings, which face to center of the gauze mask main body, are formed between the jacket layers and the inner surface of the gauze mask main body. The anti-dust gauze mask provided by the invention is simple in structure, and a filter layer can be simply and rapidly mounted and detached; and in addition, in a service process, halitus, which is exhaled from a user, is prevented from being discharged out from the top of the gauze mask to eyes of the user.

Description

technical field [0001] The invention relates to the field of personal protection devices, in particular to a dustproof mask. Background technique [0002] Dust masks can filter the air entering the human respiratory tract to a certain extent. Wearing a dust mask can effectively prevent the mouth or nasal cavity from inhaling harmful substances in the air, thereby reducing the threat of air pollution to human health. Dust masks usually include a filter layer, but the filter layer has a certain lifespan. In order to save costs, usually only the filter layer needs to be replaced during the use of the dust mask. But the dustproof respirator of prior art, it is all more complicated to the structure that filter layer is fixed usually, easily causes inconvenience to filter layer installation and dismounting. [0003] Therefore, it is necessary to provide a new dustproof respirator that simplifies the installation and removal of the filter layer. Contents of the invention [000...
