Description

Protective mask

Technical Field

The utility model relates to the technical field of protective masks, in particular to a protective mask.

Background

Face masks are tools used to protect the face and neck from flying metal debris, hazardous gases, liquid splashes, metal and high temperature solvent flying dust. Mainly comprises a welding mask, an anti-impact mask, a radiation-proof mask, a smoke-dust-proof poison gas mask, a heat-insulating mask and the like.

The common medical protective mask mainly comprises a transparent baffle plate positioned in front of the face and an elastic belt used for connecting the transparent baffle plate to the face; however, since the protective function of the protective mask is weak, the user still needs to wear the mask, thereby achieving a more sufficient protective effect. However, because the mask is worn for a long time, not only is an impression easily generated on the nose to cause a 'face' of the mask, but also the rear part of the ear is uncomfortable due to the compression of the mask rope, so that the use effect is poor.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

Example 1

As shown in figures 1 to 2 of the drawings,

a protective mask, comprising a protective mask,

the transparent body 1, the cross section of the transparent body 1 is arc-shaped;

the two ends of the head connecting belt 2 are connected to two sides of the top of the transparent body 1;

the chin connecting strap 3, both ends of the chin connecting strap 3 are connected to the lower side of the head connecting strap 2, and a set distance is arranged between the chin connecting strap 3 and the transparent body 1;

the top of the filter layer 4 is connected with the head connecting belt 2, and two sides of the filter layer 4 are respectively connected with the chin connecting belt 3 and the transparent body 1.

The head connecting strap 2 is made of an elastic material, and the longitudinal section of the head connecting strap 2 is rectangular. The chin strap 3 is made of an elastic material, and the chin strap 3 has a rectangular cross section.

The inside of top of transparent body 1 is provided with inoxidizing coating 5, the both ends of inoxidizing coating 5 with the both ends of head connecting band 2 are connected.

The transparent body 1 comprises an anti-fog part 6, and the anti-fog part 6 is opposite to eyes of a user; the antifogging part 6 can be made of the same material as the transparent body 1, and is specially used for coating house spraying or antifogging coating on the area during use; the material may be formed of an antifogging material, so that mist generation can be prevented. The transparent body 1 is provided with a ventilation opening 7 facing the mouth of a user, and two sides of the top of the transparent body 1 are provided with first limit hooks. An anti-slip ring 8 is arranged on the periphery of the outer wall of the ventilation opening 7.

When a user uses the mask, the head connecting belt 2 is sleeved on the top of the head, the chin connecting belt 3 is connected at the bottom of the chin, meanwhile, the transparent body 1 is opposite to the face of the user, and the filter layer 4 can filter air, so that the air entering the mouth and nose of the user is filtered by the filter layer 4, and safety, cleanliness and the like are ensured; meanwhile, the mask is not required to be worn on ears, so that the compression of the ears and the nose is prevented, and the use effect is better; wherein the filter layer 4 is preferably made of the same material as the mask, namely comprises a (outer layer) water-resistant layer, a (middle layer) filter layer 4 and a (inner layer) water-resistant layer. Furthermore, since the overall area of the filter layer 4 is larger than that of the mask at this time, the service life of the filter layer 4 is longer, that is, the mask does not need to be frequently replaced, and the safety can be improved in special cases. Wherein the filter layer 4 can be integrated with the transparent body 1 and the like, and the whole product is disposable; the filter layer 4 can be detachably connected with the transparent body 1, the head connecting belt 2, the chin connecting belt 3 and the like through adhesion (adhesive tape or magic tape) and the like, so that the filter layer 4 is only required to be replaced each time, and the use cost is reduced.
