Abstract

The utility model discloses a natural mineral absorption filtering mask and adopts the technical proposal that the natural mineral absorption filtering mask is a subelliptical calathiform mask, a groove cavity for receiving the nose and the mouth is arranged at a right inside of the mask, a part contact with the face inclines inward to a groove cavity (3) within 2 to 10 degrees and four through holes are drilled on a front surface of the mask. The natural mineral absorption filtering mask can absorb the smoke dust, the noxious gas and the harmful germ less than 5 micrometers effectively, so as to avoid the smoke dust, the noxious gas and the harmful germ from being absorbed directly to an alveolus and ensure the health of the user. The utility model has the advantages of small respiratory resistance, light weight and foreign flavor absorption, and can be used repeatedly after sterilization and drying. The utility model is suitable for producing the subelliptical calathiform absorption filtering masks.

Description

Natural mineral absorbing filter gauze mask

Technical field:

The utility model relates to mouth mask, is specifically related to a kind of natural mineral absorbing filter gauze mask.

Background technology:

Long-term work if do not use suitable protective mask, can damage human respiratory under the environment with dust or toxic gas.The injury of lung organ and tissue is normally very serious and can't restore, and dust is fine more, the easy more bronchus end that enters, and lethality is big more.

The height of mouth mask dust collection efficiency be with it to fine dust, especially the barriering efficiency to the respirable dust below 5 microns is a standard, because the dust of this particle diameter can directly suck alveolar, to having the greatest impact that health causes.General cotton cloth respirator, its resistance dirt principle is that mechanical type filters, exactly when dust collides gauze, through-layer by layer obstruct, with some big dust particles obstructs at Sha Buzhong.But, to some fine dusts, especially, will from the mesh of gauze, pass less than 5 microns dust, enter respiratory system.

Hood-shaped shape of very moment and the not driving fit of people's face, airborne danger equally never driving fit place leaks into, portion of air is filtered without mouth mask at all, just directly entered the human respiratory tract, cause many harmful germs together to enter human oral cavity, the through tracheae of nasal cavity and lung, cause the infection of the upper respiratory tract in company with air.

Mostly the filtrate of cotton cloth respirator generally is some mechanical fabrics, and this filtrate will reach high dust collection efficiency, and unique method increases thickness exactly, and the negative effect of increase thickness allows the user feel that respiratory resistance is very big exactly.Even if select the good again mouth mask of filtrate for use, also can't ensure the health of human body.

Summary of the invention:

The purpose of this utility model is to overcome weak point in the prior art, provides a kind of and has the dust collection efficiency height and can adsorb the natural mineral absorbing filter gauze mask of peculiar smell function.

The utility model is achieved by following technical proposals:

Natural mineral absorbing filter gauze mask is a kind of semiellipse bowl-type mouth mask, and the Right Inboard of mouth mask has the groove cavities that can hold nose and face, mouth mask contact with human body face part in groove cavities (3), tilt 2～10 the degree, be drilled with 4 through holes in the front of mouth mask.

To use water-moistened natural-minerals adsorptive filter medium, add in the mouth mask mould, the working pressure machine is pressed into the blank of natural mineral absorbing filter gauze mask, send into to dry and carry out nature in the room and dry, after the water content of blank is less than 15%, blank is transported to carries out roasting in the calcining kiln, roasting time is 12～16 hours, sintering temperature is controlled at 300～400 ℃, and the cooling back is a natural mineral absorbing filter gauze mask.

Natural mineral absorbing filter gauze mask intensity is good, there is a large amount of micropores semiellipse bowl-type mouth mask inside, and these micropores are labyrinth-like, the eupnea that not only can satisfy the people is required from the fresh air of mouth mask by filtering, and resistance dirt is effective, respirable dust and the harmful germ of energy adsorption filtration below 5 microns avoids dust and harmful germ directly to suck alveolar, guarantees user's health.

The Right Inboard of natural mineral absorbing filter gauze mask has a semiellipse bowl-type groove cavities, gives nose and very big space of face of people, and user's speech and breathing can be unobstructed freely; Semiellipse bowl-type mouth mask contacts with the human face steadily, the edge good seal, and the micropore of natural mineral absorbing filter gauze mask can increase the comfort of user's face.

Natural mineral absorbing filter gauze mask has the advantages that respiratory resistance is little, in light weight, can adsorb peculiar smell, but repeated multiple times is used after sterilization and drying.

The utility model is applicable to the absorbing filter gauze mask of production semiellipse bowl-type.

Description of drawings:

Fig. 1 is the schematic diagram of natural mineral absorbing filter gauze mask, and Fig. 2 is that the A of Fig. 1 is to view.

As shown in the figure: the 1st, natural mineral absorbing filter gauze mask, the 2nd, natural-minerals adsorptive filter medium, the 3rd, groove cavities, the 4th, mouth mask and human body face contact portion, the 5th, through hole.

The specific embodiment:

Below in conjunction with embodiment, the utility model will be further described.

Natural mineral absorbing filter gauze mask (1) is a kind of semiellipse bowl-type mouth mask, the Right Inboard of mouth mask (1) has the groove cavities (3) that can hold nose and face, the part (4) that mouth mask (1) contacts with human body face tilts to groove cavities (3) in and 6 spends, and is drilled with 4 through holes (5) in the front of mouth mask (1).

Will be with water-moistened natural-minerals adsorptive filter medium (2), add in the mouth mask mould, the working pressure machine is pressed into the blank of natural mineral absorbing filter gauze mask (1), send into to dry and carry out nature in the room and dry, after the water content of blank is less than 15%, blank is transported to carries out roasting in the calcining kiln, roasting time is 12 hours, sintering temperature is controlled at 300～350 ℃, and the cooling back is natural mineral absorbing filter gauze mask (1).

Claims

1. natural mineral absorbing filter gauze mask, it is characterized in that, natural mineral absorbing filter gauze mask (1) is a kind of semiellipse bowl-type mouth mask, the Right Inboard of mouth mask (1) has the groove cavities (3) that can hold nose and face, the part (4) that mouth mask (1) contacts with human body face tilts to groove cavities (3) in and 2～10 spends, and is drilled with 4 through holes (5) in the front of mouth mask (1).
