Abstract

The utility model relates to a guard mask, which is made of multiple layers of gauze. The upper end of the inner side of the utility model is provided with a nose clip made of plastic material, a curved line of the nose clip is close up to face, and the curved line is similar to a face curved line at a nose bridge point. The nose clip is divided into an inner layer and an outer layer, a supporting rib is arranged between two layers to form an air bag. The gauze is lined with a layer or a plurality of layers of high efficiency nonwoven fabric isolation layers made of fuse spray plastics, and the high efficiency nonwoven fabric isolation layers have nanometer grade pore diameters. Since the upper edge of the mask and the face curved line have good fit, air without filtration is prevented from entering the mask, and the mask can prevent heat air from escaping from the nose bridge point. An elastic air bag structure in the nose clip makes a user to have no suffocation sense when breathes. The high efficiency isolation layers can filter small dust and bacteria in the air, and the guard effect is improved.

Description

Protective mask

Affiliated technical field

The utility model relates to a kind of protective mask.

Background technology

In the prior art, mouth mask is made by the multilayer gauze and is formed.Because mouth mask upper edge and facial bridge of the nose place curve can not coincide well, so the air of part filtered is from the suction of bridge of the nose both sides, and only is that the filter effect of filter course is limited with the gauze; Simultaneously because there is the slit in the mouth mask upper edge, the hot gas of exhalation can be overflowed from bridge of the nose both sides, makes to produce fog on the glasses, influence sight line, moreover its gauze layer is close to face, blocks nasal cavity, makes us the sense of feeling suffocated when breathing; Particularly SARS is popular recently, mouth mask becomes the important protective articles that prevents the SARS droplet transmission, but because existing mouth mask, the effect of isolating SARS virus is relatively poor, medical personnel often will put on many mouth masks, the hot gas of overflowing from the mouth mask upper edge also can influence medical personnel's sight line, influences their treatment and nursery work.

Summary of the invention

In order to improve the protective action of mouth mask, the utility model proposes a kind of protective mask,, the upper edge of mouth mask is coincide with facial by its nose clip that is located at the inboard upper edge of mouth mask with the elasticity nose clip, improve its protection effect, and overcome the shortcoming that on glasses, produces aerosol easily;

Another purpose of the present utility model is to add efficient filtering layer in the gauze layer of mouth mask, to improve the filtration of mouth mask to bacterium and dust;

Another purpose of the present utility model is by the airbag structure on the nose clip mouth mask to be propped up, and makes to form a little space in the mouth mask, to overcome the sense of feeling suffocated of mouth mask.

A kind of protective mask of the present utility model is made by the multilayer gauze, and the side upper edge is provided with a nose clip of being made by rubber or non-toxic polyvinyl chloride plastic material within it, and described nose clip is pressed close to the curve and bridge of the nose place face curve approximation at facial place.

This nose clip has inside and outside two layers, is provided with ribs between two layers, forms a resilient air bag.

In described mouth mask gauze, be lined with one or more layers with melting and spraying that plastics are made, as to have the nanoscale aperture efficient nonwoven separation layer.

Effect of the present utility model is: owing to set up the nose clip of being made by a kind of plastic material in the mouth mask upper edge, and it presses close to the facial curve approximation of curve and bridge of the nose place at facial place, therefore when putting on mouth mask, the facial curves at mouth mask upper edge and bridge of the nose place gets very good, the air that can prevent filtered enters in the mouth mask, can prevent that again the hot gas in the mouth mask from overflowing from the bridge of the nose, at the glasses upper fogging, influence sight line, and the elastic bag structure in the nose clip, make to have a cushion space in the mouth mask, do not have the sense of feeling suffocated when air-breathing exhaling; The efficient separation layer of Xin Zeng nonwoven can filter out airborne tiny dust and bacterium simultaneously, has improved protection effect.

Description of drawings

Fig. 1 is the schematic diagram of protective mask of the present utility model.

The specific embodiment

Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.

An embodiment of the present utility model as shown in Figure 1.

The inboard upper edge of mouth mask body 1 is sewed with a nose clip 2 by rubber or non-toxic polyvinyl chloride compression molding, and this nose clip 2 is pressed close to the facial curve approximation of curve and bridge of the nose place at facial place.Described nose clip has inside and outside two layers, forms an air bag 2a between two layers, is provided with ribs 2b in the air bag, makes the air bag high resilience.In order to improve the filter effect of mouth mask, in the mouth mask gauze, be lined with one or more layers with melting and spraying that plastics are made, as to have the nanoscale aperture efficient nonwoven separation layer.

Claims

1. a protective mask is made by the multilayer gauze, it is characterized in that being provided with in the inboard upper edge of this mouth mask a nose clip of being made by plastic material, and described nose clip is pressed close to the curve at facial place and the facial curve approximation at bridge of the nose place.

2. protective mask according to claim 1 is characterized in that described nose clip has inside and outside two layers, forms an air bag between two layers.

3. protective mask according to claim 2 is characterized in that being provided with ribs in the air bag of described nose clip.

4. according to claim 1,2 or 3 described protective masks, it is characterized in that described nose clip made by rubber or non-toxic polyvinyl chloride.
