CN103263093A - Dust mask for elastically sealing two sides of nose bridge - Google Patents

Abstract

The invention provides a dust mask for elastically sealing two sides of the nose bridge. The dust mask is clock-shaped, two sides in the bottom of the dust mask are respectively provided with one section of arc-shaped flange matched with concave parts in two sides of the nose bridge of a user, the dust mask is formed by hot pressing three layers of non-woven fabrics, active carbon is permeated in the outer layer of non-woven fabric, the middle layer is a melt-blown non-woven fabric, and the inner layer is a white sized non-woven fabric which comprises the following components of 40 percent of 4080 with low melt point, 15 percent of 6D mask for elastically sealing two sides of nose bridge, 10 percent of 2.5D common chemical fiber, 25 percent of 1.5D large chemical fiber and 10 percent of 2.78D spun large chemical fiber. The dust mask has the advantages that the mask can be clung to the concave parts in two sides of the nose bridge on the face of the user, a good sealing effect is achieved, an existing mask nose bridge depression bar is replaced, and thus the cost is lowered, and the dustproof effect of the mask is greatly improved.

Description

The anti-dust respirator of elastic packing bridge of the nose both sides

Technical field

The present invention relates to a kind of anti-dust respirator, be particularly to a kind of and anti-dust respirator people's face high-seal.

Background technology

Anti-dust respirator in the market, the subject matter of existence be, poor sealing performance, and extraneous dust can leak in the import cover from the chase of people's bridge of the nose both sides, and dustproof effect is bad, influences health.

Summary of the invention

For solving aforementioned problem of depositing, the invention provides the anti-dust respirator of a kind of elastic packing bridge of the nose both sides, mouth mask is bell, there is one section curved flanges and people's the bridge of the nose both sides recess coupling both sides in the mouth mask bottom, mouth mask forms with three layers of nonwoven hot pressing, and outer nonwoven is impregnated with active carbon, and the intermediate layer is melt spraying non-woven fabrics, nexine is white typing nonwoven, and the prescription of described white typing nonwoven is:

4080 low melting points 40%;

6D terylene short fiber 15%;

2.5D common chemical fibre 10%;

1.5D big chemical fibre 25%;

2.78D spin big chemical fibre 10%.

The invention has the advantages that, mouth mask two side flanges that are hot pressed into typing nonwoven of the present invention, both soft, also has elasticity, can be close to the chase of people's face bridge of the nose both sides, reach good sealing effectiveness, replace existing mask nose bridge batten, not only reduce cost, also improved the dustproof effect of mouth mask greatly.

Description of drawings

Fig. 1 is front view of the present invention;

Fig. 2 is the side view of Fig. 1;

Number in the figure explanation: 1-mouth mask body; The recess of 2-mouth mask the place ahead and arranged on left and right sides; 3-mouth mask the place ahead lug boss; The lug of 4-mouth mask two side-line tape splicing; The flange that 5-mouth mask both sides are inside.

The specific embodiment

See also shown in the accompanying drawing 1,2, mouth mask body 1 is bell, there is one section curved flanges 5 and people's the bridge of the nose both sides recess coupling both sides in mouth mask 1 bottom, curved flanges 5 forms at two recesses of outside, mouth mask 1 the place ahead both sides compacting 2, lug boss 3 in the middle of these two recesses 2 form simultaneously, lug boss 3 just in time coats people's the bridge of the nose, and flange 5 puts in people's bridge of the nose both sides chase, reaches good sealing effectiveness.Cooperate the belt that passes mouth mask both sides lug 4 again, make mouth mask be close to people's face, make the sealing property of this mouth mask better.

Claims (1)

1. the anti-dust respirator of an elastic packing bridge of the nose both sides, it is characterized in that, mouth mask is bell, there is one section curved flanges and people's the bridge of the nose both sides recess coupling both sides in the mouth mask bottom, mouth mask forms with three layers of nonwoven hot pressing, and outer nonwoven is impregnated with active carbon, and the intermediate layer is melt spraying non-woven fabrics, nexine is white typing nonwoven, and the prescription of described white typing nonwoven is:

4080 low melting points 40%;

6D terylene short fiber 15%;

2.5D common chemical fibre 10%;

1.5D big chemical fibre 25%;

2.78D spin big chemical fibre 10%.
