Abstract

The utility model relates to a composite dustproof gauze mask. The main body of the composite dustproof gauze mask is oval, and the circumference is provided with foofaraws which are fixedly sewed by threads. The main body is combined by a terylene layer, a superfine layer, a filter paper layer, and a foam layer. The upper part of the main body is sewed with a nose cover, and the middle small position is provided with a hole. An active angle which is composed of an outer sleeve and an inner sleeve is positioned in the hole. The end surface of the outer sleeve is provided with six holes, a shim is a circular slice, the end surface is provided with a half annular slot, the shim can be arranged between the inner and the outer sleeves and can be arranged at a slot outside. The composite dustproof gauze mask can exhaust, but can not inhale. Since the shim can block a hole of the inner sleeve, dustproof effect is obvious and good.

Description

Composite dust-proof gauze mask

The utility model relates to a kind of compound anti-dust respirator, belongs to the technical field of dustproof utensil.

In the workplace of dust work, and medical department, the mouth mask that mostly uses cotton gauze to make, add the thin cotton of one deck between two-layer cotton gauze, also have coldproof function in the winter time, its shortcoming is that mouth mask presses mouth nose position, will feel to feel suffocated with a period of time slightly, and be easy to dirtyly, almost can not re-use the existing sponge plastics that adopt of some mouth mask after cleaning, but moulding is simple and crude, similar breathing mask is out of favour in the use, demands urgently improving.

The purpose of this utility model is that a kind of compound anti-dust respirator will be provided, and it can overcome above-mentioned deficiency, selects light and soft material for use, terylene foam ultrafiltration paper is sewed up and is formed, and man's cap used in ancient times alive (soaker) is housed, and anti-dust performance is significantly improved, clean easy, durable in use.

The purpose of this utility model is achieved in that main body is oval, has ruffle around the appearance, use suturing with thread management, main body is by terylene ultrafiltration paper and foam is four-layer seamed forms, and mouth mask top internal layer is sewed with nose cup, also is oval, there is slotted hole on the main body both sides, elastic cord is housed in the hole, and the main center position is porose, packs in the hole by the synthetic man's cap used in ancient times alive of interior cover overcoat shim pack, the overcoat end face has 6 holes, and pad has semi-circular groove.

Now in conjunction with the accompanying drawings the structure of compound anti-dust respirator is described in detail:

By Fig. 1, mask main body (1) is oval, centre bit is equipped with a hole, the Kong Zhongke man's cap used in ancient times alive (soaker) (3) of packing into, main body (1) has a ruffle (2) around the outside, it is the edge of PE sizing material, be seamed into along seam solidus (7) with line, ruffle (2) and main body (1) seam are integral admittedly, there is a slotted hole (8) ruffle (2) both sides, whippy nylon tape or degree of tightness strap (4) are housed in the hole, the top in main body (1), main body (1) internal layer stitches the nose cup (5) that solid one deck is made by sponge again.

By Fig. 2, main body (1) is made up of four layer materials, and ground floor skin (9) is a terylene; both soft, lovely luster, gas permeability are better again; durable in use, can play the effect of protection to mouth mask, be difficult for dirty; also be easy to clean up, intensity is good, and is not fragile; the second layer and the 4th layer of internal layer (10) (21) are foams, are rich in resilient flexible, touch with hand rubbing also to be rich in soft sensation; main is that anti-dust performance is more excellent, and the 3rd layer of nexine (11) is to select ultrafiltration paper for use.

By Fig. 3, Fig. 4, the inner chamber of the man's cap used in ancient times overcoat (12) of living is step groove (13), and there are 6 holes (14) on the bottom land surface.

By Fig. 5, cover (15) left end porose (16) in the man's cap used in ancient times of living, right-hand member has flute profile inner chamber (17).

By Fig. 6, pad (18) is a thin rounded flakes, and end face has semi-circular slotted eye (19).

By Fig. 7, the external diameter of pad (18) is than smaller 1 millimeter of the internal diameter of man's cap used in ancient times overcoat alive (12) step groove (13) bottom land, make pad (18) can insert in the groove, the external diameter of cover (15) left part and the internal diameter of step groove (13) adapt in the man's cap used in ancient times alive, and therefore interior cover can be sleeved in the overcoat (12).

When the man's cap used in ancient times anti-dust respirator of living uses, nose cup (5) can cover nose, the structure exhaust easily of man's cap used in ancient times owing to live, discharge by the hole (16) of interior cover (15) and 6 holes (14) of overcoat (12), when air-breathing, pad (18) can be covered the hole (16) of interior cover (15), thereby can not suck dust, pad (18) is side-to-side vibrations in respiratory, plays bigger effect to preventing dust.

Compared with prior art, the man's cap used in ancient times anti-dust respirator of living has following advantages:

1. anti-dust respirator is by terylene, two-layer foam, and one deck ultrafiltration paper, four layer materials are sewed up and are formed, and good permeability is durable in use, is easy to clean up.

2. moulding is lightly attractive in appearance, makes to make things convenient for.

3. special man's cap used in ancient times alive (dust exhaustor) is housed, significantly improves dustproof effect.

4. be applicable to the department of dust work.
