The anti-dust mask used in the coal mine comprises a face mask support (1), wherein clamping plates (3) are arranged on the two sides of the face mask support (1) respectively, a double-filtration piece (4) is arranged between the clamping plates (3), the two sides of the double-filtration piece (4) are inserted into the clamping plates (3) respectively, an air valve (5) is arranged on the double-filtration piece (4), a protecting layer (6) is arranged on the inner surface of the double-filtration piece (4), and hanging ropes (2) are arranged on the two sides of the face mask support (1) respectively.
Description
Technical field
The present invention relates to a kind of colliery anti-dust respirator.
Background technology
Current filtration members adopts single layer filter, and the filter effect of this mouth mask is poor, and dismounting is more difficult, and service life is shorter.
Summary of the invention
The invention provides a kind of colliery anti-dust respirator, it has not only strengthened the adsorption capacity of dust, and dustproof reliability and security are higher, and dust containing capacity is larger, longer service life.
The present invention has adopted following technical scheme: a kind of colliery anti-dust respirator; it comprises mask support frame; both sides at mask support frame are provided with clamping plate; between clamping plate, be placed with two filters; insert in clamping plate the both sides of two filters; on two filters, be provided with air valve, be provided with protective layer at the inner surface of two filters, be provided with lanyard in the both sides of mask support frame.
Described air valve is notch cuttype air valve.Described protective layer is medical silica-gel.Described lanyard is set to elastic cord.
The present invention has following beneficial effect: adopted after above technical scheme, the present invention adopts two filters, can strengthen like this adsorption capacity of dust, and dustproof reliability and security are higher, and dust containing capacity is larger, longer service life.Air valve of the present invention is notch cuttype air valve, longer service life like this, and respiratory resistance is lower, seals tighter.Protective layer of the present invention is medical silica-gel, so more approaches human body hardness, Polymethyl Methacrylate.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
