Embodiment Construction

[0030] The structure of the present invention will be further described below with reference to the accompanying drawings.

[0031] like figure 1 , figure 2 and image 3 As shown, the present invention provides a bowl-shaped three-dimensional folding dust mask, the inner layer of the mask is a non-woven skeleton 1, the outer layer is a face cloth 4, and between the inner and outer layers are a filter cloth 2 and a mesh cloth 3. There is a horizontal welding line 5 in the middle section of the mesh cloth 3, which is connected with the horizontal welding line 5 and extends down to the edge of the mouth to have a vertical welding line 6, which can be folded along the horizontal welding line 5 and the vertical welding line 6. Silicone rubber is pasted on the nose bridge and forehead of the face contact surface, and a one-way exhalation valve 7 is provided on the side below the horizontal welding line 5 .

Abstract

The invention discloses a bowl-shaped three-dimensional folding dustproof mask. The inner layer of the mask is a non-woven fabrics skeleton, and the outer layer is shell fabric, and filter cloth and grid cloth are arranged between the inner layer and the outer layer; the middle section of the grid cloth is a horizontal weld line, and a vertical weld line which is connected with the horizontal weld line extends downwards to the opening edge; the grid cloth can be folded along the horizontal weld line and the vertical weld line; the mask is stuck with silicon rubber on one surface which contacts with the bridge of the nose and the lower forehead of a human face; and an one-way expiratory valve is arranged on one side below the horizontal weld line. The invention has the advantages that the bowl-shaped three-dimensional folding dustproof mask can be folded, can keep original shape after being restored, and has small space usage and provides convenience for packaging and transporting, and a user can conveniently put the mask in the pocket.

Description

technical field [0001] The invention relates to a mask, in particular to a bowl-shaped three-dimensional folding dust mask. Background technique [0002] At present, the existing three-dimensional masks must not be squeezed or bent, and occupy a large volume, which brings great inconvenience to packaging and transportation. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a bowl-shaped three-dimensional folding dust mask that can be folded and occupies a small volume. [0004] In order to solve the above technical problems, the present invention provides a bowl-shaped three-dimensional foldable dust mask. The inner layer of the mask is a non-woven fabric skeleton, the outer layer is a face cloth, and a filter cloth and a mesh are arranged between the inner and outer layers. There is a horizontal welding line in the middle section of the mesh cloth, which is connected to the horizontal welding line and extends down...
