Brief description of the drawings
Fig. 1 is schematic diagram provided in an embodiment of the present invention；
Fig. 2 is each part dispersed structure figure.
In figure：1st, main body frame, 2, hanger, 3, filter, 4, outer block cloth, 5, interior block cloth, 6, VELCRO, 7, chamber.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1 and 2, a kind of replaceable protective mask, including the hanger 2 of mask body and mask body both sides are referred to,
Described mask body includes main body frame 1, filter 3 and the block cloth for being fitted in main body frame both sides, as illustrated, including
Outer block cloth 4 and interior block cloth 5, it is bonded by VELCRO 6 with the both sides of main body frame 1, outer block cloth 4 and interior block cloth 5 use non-woven fabrics
Material.
Described main body frame 1 is hollow structure, and its inside has chamber 7, the side that described filter can be to pull and push
Formula is arranged in internal chamber.
Described filter 3 has multiple micropores, and its material is prepared by nano particle.
Its mouth mask of the invention uses frame structure, and outside is pasted using VELCRO and block cloth, forms a complete mouth mask
Structure, main body frame are hollow structure, and its inside has chamber, and described filter is arranged in internal chamber, this spline filter
Plate can easily pull and push replacing, realize secondary use.
Secondly above all the material of the filter of the present invention uses what bimetallic support type material for air purification used
