Description

Combined protective mask

Technical Field

The invention relates to the field of masks, in particular to a combined protective mask.

Background

The protective mask is a common protective tool, is worn on the head to protect the respiratory organs, eyes and the face of a person, and can prevent toxic gas, dust, bacteria, toxic and harmful gas or steam and other toxic substances from damaging the human body. The method is widely applied to the fields of petroleum, chemical engineering, mines, metallurgy, military, fire fighting, emergency rescue and relief, health and epidemic prevention and the like, and plays an important role in protecting the respiratory system of a human body. In 3M protective face mask among the prior art, the protective face mask designs and adopts the great active carbon of volume to filter the module and integrate mostly, and whole bulky, and do not separate the processing to gauze mask portion and eye protection portion, because exhale when using easily and can form water smoke on the lens, influence the sight. In addition, on the material consumption of the consumable, the whole is often directly replaced, the proper filter element is not considered to be replaced according to the requirement, and the consumption of materials is saved.

Disclosure of Invention

Based on the above, the invention provides the combined protective mask, which improves the utilization rate of the mask and reduces waste by replacing the filter cloth and reserving the mask. And the sealing edge and the isolating edge are arranged through the rubber coating process, the mask is designed into two independent cavities of the mouth mask part and the eye protection part, and the influence of water vapor exhaled by the mouth and the nose on the sight is reduced.

In order to realize the purpose of the invention, the invention adopts the following technical scheme:

a combined protective mask comprises a main body, a cover plate, filter cloth, a fixed head band and a fixed neck band; the main body comprises an eye protection part and a mask part which are integrally formed by adopting an injection molding process; the middle part of the outer side of the mouth mask part is provided with a filter tank, the bottom of the filter tank is provided with a plurality of air holes and filter cloth dismounting holes, and the filter cloth dismounting holes are used for ejecting the filter cloth out of the filter tank; the cover plate is detachably arranged on the outer side of the mouth cover part, a grid plate is distributed on the outer side of the cover plate, a dustproof bulge is arranged in the middle of the grid plate, a pressing bulge is further arranged on the inner side of the cover plate, and the pressing bulge fixes the filter cloth on the filter tank; the fixed head bands are connected to two sides of the eye protection part, the fixed head bands are used for fixing the main body after passing around the brain, the fixed neck bands are connected to two sides of the side edges of the mask part, the fixed neck bands are used for fixing the main body after passing around the neck, and the end of the main body of the fixed neck band principle is further provided with an elastic adjusting buckle; the edge all around of main part is connected with the sealed limit, sealed limit middle part still is equipped with the isolation limit, the isolation limit separates into two cavities with the inboard eye protection portion of main part and gauze mask part. The separation of the two chambers can effectively prevent the air exhaled by the mouth and the nose from forming atomization in the eye protecting part. The mouth and nose protection and the glasses protection are integrated, and the protection effect is better.

Furthermore, fixed bandeau can dismantle through the conversion knot and connect in protect the mesh portion, fixed nape can dismantle through the conversion knot and connect on the gauze mask portion, fixed bandeau and fixed nape are elastic nylon belt and make.

Further, the sealing edge is connected to the main body through an encapsulation injection molding process.

Furthermore, the sealing edge is made of elastic plastic and is used for being tightly attached to the skin of a human body.

Furthermore, the area of the filter cloth is larger than that of the filter tank and smaller than that of the pressing bulge.

The invention has the beneficial effects that: the sealing part, the main body part, the cover plate part and the fixing band part of the combined mask can be used for a long time. The filtering part can be conveniently replaced, and the filter cloth only covers a breathing area, so that materials are greatly saved. Meanwhile, the filter cloth with different functions is replaced, so that different protection effects can be achieved. The eye protection part and the mask part are integrally designed and are provided with the isolation edges, so that the protection effect is improved.
