Abstract

The utility model relates to a sealed nonwoven fabric dustproof gauze mask used in the industries of mine collection, cement manufacture, chemical industry, medical sanitation, powder metallurgy, environmental protection and dust, and other industries which are seriously polluted. The utility model is composed of a gauze mask body and lacings, wherein, the gauze mask body is composed of three layers of nonwoven fabric material and a sealed layer, the outer layer is a filtering and decorative layer with primary efficiency, the middle layer is a filter layer with high efficiency, the inner layer is a moistureproof and dampproof layer, and the sealed layer in contact with a face is a sealed pad ring; the lacings are elastic strainer lacings; the gauze mask body forms a bocky shape. Light nonwoven fabric material is adopted by the utility model, and the shape corresponds to the face shape and the nose shape of a human body. The utility model has the advantages of good adhesive performance, light and comfortable wear, fluent breath, wide filtering area and high dustproof efficiency. The utility model has more than 0.3 mum dispersing particulates, and dustproof rate achieves more than 99%.

Description

Sealed nonwoven gauze mask

The utility model relates to a kind of sealed nonwoven anti-dust respirator that is used in dust such as mine collection, cement manufacturing, chemical industry, medical and health, powder metallurgy, environmental sanitation and seriously polluted industry.

Existing cotton cloth respirator is to make with eight layers or Floor 12 gauze to form; be shaped as plane; its gauze organizes hole big; materials are many, when covering on the mouth and nose place simultaneously and the stickiness of face poor, two of the wings of nose have hole; thereby particulates such as airborne dust, germ can enter in the cover thereupon; infection is caused in inlet port (nose) chamber, and human body produces disease.

The purpose of this utility model provides a kind of sealed nonwoven anti-dust respirator that adopts nonwoven material and moulding to meet people's face nose type, prevents effectively in the particulate inlet port nasal cavities such as dust, germ, has overcome the shortcoming that existing mouth mask exists.

The purpose of this utility model is achieved in that sealed nonwoven anti-dust respirator, it is made of cover body and frenulum, it is characterized in that cover body is made up of three layers of nonwoven and sealant, skin is the primarily efficient filter decorative layer, the intermediate layer is that high efficiency filter layer and internal layer are moistureproof damp course, the sealant that contacts with face is a seal washer, and frenulum is a rubber-like degree of tightness cingulum, and the profile of cover body is the wooden dipper shape.

The utility model adopts the light non-woven fabrics material, and appearance meets people's face nose type, and stickiness is good, wears gently and comfortablely, breathes smooth and easyly, and filter area is big, dustproof efficient height, and the above discrete particles of the 0.3 μ m rate of preventing dust reaches more than 99%.It has simple in structure, handling ease, and economy and durability, disposable being with more than three months is convenient to washing and use repeatedly.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is illustrated in detail.

Fig. 2 is an inboard schematic diagram of the present utility model

Fig. 3 is a cover body front view of the present utility model

Fig. 4 is a cover body cutaway view of the present utility model

Among the figure: 1. frenulum, 2. cover body, 3, primarily efficient filter decorative layer, 4. high efficiency filter layer, 5. moistureproof damp course, 6. seal washer.

As Figure 1-3: sealed nonwoven anti-dust respirator, it is made of cover body (2) and frenulum (1), it is characterized in that cover body (2) is made up of three layers of nonwoven and sealant, outer is that primarily efficient filter decorative layer (3), intermediate layer are that high efficiency filter layer (4) and internal layer are moistureproof damp course (5), the sealant that contacts with face is seal washer (6), and frenulum (1) is flexible degree of tightness cingulum.Primarily efficient filter decorative layer (3) adopts the perverse method nonwoven cloth material of water, high efficiency filter layer (4) adopts imitative sticking method nonwoven cloth material, moistureproof damp course (5) adopts meltblown one-way nonwoven cloth material, degree of tightness textile tapes such as seal washer (6) adopts the neutral plastics of the low bubble of high density, and frenulum (1) employing is cotton, wash.As shown in Figure 4: cover body (2) adds man-hour, earlier with three layers of nonwoven (3) (4) (5) and low steep plastic washer (6) and press the level laying after, PUR is coated at every layer of edge, put into the mould that the face nose type by the people is designed to then, once hot-forming, the outer formation wooden dipper shape of cover body (2), whole body resembles PERICARPIUM LAGENARIAE.This cover body (2) need not support by skeleton, can form suitable cavity naturally, breathes freely, and coating performance is good, has eliminated the hole of wing of nose both sides, prevents completely effectively in the particulate inlet port nasal cavities such as dust, germ.Simultaneously the internal layer (5) of cover body (2) adopts the one-way nonwoven cloth material, the aqueous vapor of exhalation can only to the external world discharge and extraneous aqueous vapor can the mask for inhalation chamber in, do not have the sense of discomfort, not yielding after the washing, can use repeatedly.
