Abstract

The utility model relates to a two-band closed dust-proof mask. The body of the two-band closed dust-proof mask is folded by seven layers, such as a Telikedesi material layer, a foamed cotton layer, a filter paper layer, an activated carbon layer, a gauze layer, etc.; the periphery of the outer layer is inlaid with a side frame which is sewn with the outer layer together; the upper end of the two-band closed dust-proof mask is sewn with a tongue-shaped piece, and both sides of the side frame are provided with two convex lugs which are tied with two elastic bands.

Description

Biobelt driving fit anti-dust respirator

The utility model relates to a kind of anti-dust respirator, belongs to the technical field of mouth mask.

Some industry regular meeting some foul gas of outside seepage flow; even also have the gas that has toxicity; mouth mask commonly used is by two-layer gauze; the thin cotton of middle filling one deck; the real difficult this smell that suppresses; unhealthful, mainly adopt the sponge plastics to make mouth mask, gas permeability is very poor; band feels to cast aside gas and uncomfortable when wearing; and make coarse and crude, utmost point sense inconvenience during use, the same like weaing a gas mask; therefore be out of favour; mouth mask uses an elastic cord, and mouth mask can not be fitted tightly in face, and the effect of mouth mask is weakened.

The purpose of this utility model is that a kind of anti-odour mouth mask will be provided, and it can remedy above-mentioned deficiency, and mask main body is by multiple material, compositions such as foam, filter paper, active carbon, gauze, inlay with PE material frame, the lug of frame both sides is fixed with 2 elastic cords again, and the Use Limitation fruit better.

The purpose of this utility model is to realize like this;

A kind of biobelt driving fit anti-dust respirator, the skin (1) that it is characterized in that body is the Te Likedesi material of one deck light soft, the 2nd layer is foam (2), the 3rd layer is filter paper (3), the 4th layer is active carbon layer (4), the 5th layer is filter paper (5), the 6th layer is again foam (6), the 7th layer of internal layer side is gauze (7), seven stacked skin (1) insert one frames (8) all around that are combined in are stitched into one, and the mouth mask upper end is sewed up a tongue-like pieces (9) again, all there are 2 lugs (11) frame (8) left and right sides, and 2 elastic cords (10) are fastened separately in lug (11).

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, this dust-protection type mouth mask, the skin of body (1) are to be made by the Te Likedesi material of light soft, and it is soft thin as spun yarn, the second layer is foam (2), smooth surface, springiness, intensity is suitable, the 3rd layer is filter paper (3), the 4th layer is active carbon layer (4), and the 5th layer is again that (50, the 6 layers also is foam (6) to filter paper, the 7th layer of side is one deck gauze (7), after 7 stacked the closing,, be integral with suturing with thread management at outer (1) insert one PE sizing material frame (8) all around, suture (12), as shown in phantom in FIG., sew up a tongue-like pieces (9) again, can cover nose during use in mouth mask body upper end, all there are 2 lugs (11) left and right sides of frame (8), then 2 elastic cords (10) fasten separately in about above 2 lugs (11), adopt 2 elastic cords (10) that mouth mask is fitted tightly in face, improve its dustproof effect, frame (8) adopts harder P E sizing material, can guarantee that mouth mask has enough intensity, make it not fragile, PE is a polythene material.

Compared with prior art, Double strip covering dust-proof mouthpiece has following advantage:

1, mouth mask is light and soft soft, and good air permeability is very comfortable when wearing;

When 2, mouth mask is dirty, be easy to clean the capable person;
