Abstract

The utility model relates to a double-strip tight-covering dust-proof mouthpiece. The main body of the double-strip tight-covering dust-proof mouthpiece is composed of an outer layer, a foamed cotton layer, a filter paper layer, an active carbon layer, a filter paper layer and a foamed cotton layer which are folded with each other; the periphery of the outer layer is matched with side frames which are sewn together by threads, and lugs of the side frames are connected with each other by an elastic belt. When the utility model used, the elastic belt can ensure the mouthpiece to be tightly attached to face part. With favorable air permeability, when the utility model is used, users can not feel suffocated, and the utility model can also isolate odor or gas with toxicity.

Description

Biobelt driving fit anti-dust respirator

The utility model relates to a kind of driving fit anti-dust respirator of being with again, belongs to the technical field of life mouth mask.

Mouth mask commonly used generally uses two gauzes, and middle filling is stitched into one with thin cotton layer, two ends, the left and right sides connect with thin cotton cord, this mouth mask can not fit tightly in cheek, and gauze is easy to dirtyly, cleans the back cavitoma, be difficult to reuse, the mouth mask that adopts plastics or foam material is also arranged later, but making is too coarse and crude, extremely uncomfortable when wearing, sometimes the sensation of feeling suffocated is in addition demanded urgently improving.

The purpose of this utility model is that a kind of biobelt driving fit anti-dust respirator will be provided, it can overcome above-mentioned shortcoming, mask main body by the Te Likedesi material as skin, all the other each layers are followed successively by materials such as foam, filter paper, active carbon, the outer configuration in superimposed back one frame, admittedly be integral with linear slit, the lug of frame both sides connects elastic cord again.

The purpose of this utility model is achieved in that

A kind of biobelt driving fit anti-dust respirator is characterized in that mask main body has a Te Likedesi skin (1), and the second layer is foam (2), the 3rd layer is filter paper (3), the 4th layer is active carbon (4), and the 5th layer is filter paper (5), and the 6th layer is foam (6), superimposed mutually, dispose a frame (8) all around in outer (1), be integral with suturing with thread management, all there are 2 lugs (7) frame (8) both sides, left and right sides lug (7) connects with 2 elastic cords (10), and mask main body top is sewed with a tongue piece (9).

Fig. 1 anti-dust respirator schematic diagram.

Now in conjunction with the accompanying drawings the structure with the driving fit anti-dust respirator again is described in detail:

By Fig. 1, the anti-dust respirator main body has a skin (1), this skin is made by soft meagre Te Likedesi material like yarn, the second layer is foam (2), the 3rd layer is filter paper (3), and the 4th layer is active carbon (4), and the 5th layer is filter paper (5), the 6th layer is foam (5), 6 stacked closing are disposed a frame (8) all around in outer (1), and this frame (8) is made with PE ebonite material, can guarantee that mouth mask has sufficient intensity, not fragile, make mouth mask can fit in face, all there are 2 lugs (7) frame (8) both sides, 2 elastic cords (1) are the lug (7) that is fixed in both sides separately, and mask main body top is sewed with a tongue piece (9).Mouth mask is fitted tightly in cheek, can not become flexible, leave the slit.

Compared with prior art, be with again closed dust-proof mask to have following advantages:

1, good air permeability does not have and casts aside the gas impression;

2, adopt sandwich structure, the effect of dustproof, anti-odour, anti-toxicity gas Better;

3, adopt 2 elastic cords and PE sizing material frame, mouth mask is fitted tightly in cheek, and do not have the slit.

Claims

1, a kind of biobelt driving fit anti-dust respirator is characterized in that mask main body has a Te Likedesi skin (1), and the second layer is foam (2), the 3rd layer is filter paper (3), the 4th layer is active carbon (4), and the 5th layer is filter paper (5), and the 6th layer is foam (6), superimposed mutually, dispose a frame (8) all around in outer (1), be integral with suturing with thread management, all there are 2 lugs (7) frame (8) both sides, left and right sides lug (7) connects with 2 elastic cords (10), and mask main body top is sewed with a tongue piece (9).
