Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a protective mask, comprising a mask body 1, wherein the mask body 1 comprises an inner layer 11 and an outer layer 12, an interlayer is formed between the inner layer 11 and the outer layer 12, the inner walls of two sides of the interlayer are fixed with a limit strip 14 in a sealing manner, a limit groove is arranged in the limit strip 14, a limit block 15 is connected in the limit groove in a sliding manner, a protective layer 13 is fixed on one side of the two limit blocks 15, the protective layer 13 comprises an oil smoke prevention layer 131, an anti-haze layer 132 and an activated carbon layer 133 which are connected in sequence, two sides of the mask body 1 are fixed with a soft edge box 2, a soft rod 6 is rotatably connected in the edge box 2, one end of the soft rod 6 penetrates through the edge box 2 and is fixedly connected with a knob 7; the front face of the mask body 1 is provided with a valve 10, and the inner layer 11, the outer layer 12, the smoke preventing layer 131, the haze preventing layer 132 and the activated carbon layer 133 are provided with breathing openings 16 at corresponding positions.

It should be noted that the above components are all made of soft or elastic material; the smoke prevention layer 131 and the anti-haze layer 132 in the protective layer 13 are conventional; the valve 10 has a unidirectional property, when breathing in, air can enter the respiratory tract only through the outer layer 12, the protective layer 13 and the inner layer 11, but when breathing out, the valve in the valve is opened, the resistance when breathing out is reduced, hot air is prevented from remaining in the protective cavity, and when the type of the protective layer 13 is switched, the positions of the breathing holes 16 in the inner layer 11, the outer layer 12 and the protective layer 13 correspond to facilitate the unidirectional discharge of the breathing out through the valve 10.

The back of gauze mask body 1 is fixed with the laminating strip 3 that is back font, and the back of gauze mask body 1 just is fixed with interior brace 9 between laminating strip 3, and the laminating face forms a breathing space, and interior brace 9 has the gas permeability, with 16 position partial coincidences of mouth of respiration, nevertheless do not influence normal use.

The middle part of the upper end of the fitting strip 3 is embedded with a nose pad 4, one side of the nose pad 4, which is far away from the mask body 1, is fixed with a water absorption strip 5, and water vapor generated in the wearing process is absorbed, so that the wearing comfort is improved.

The two side boxes 2 are fixedly connected with ear hooks 8 at the opposite sides, and the ear hooks 8 are in a bowknot shape, so that the ear hooks 8 are more firmly hung on ears.

The limiting groove and the limiting block 15 are both T-shaped, the limiting block 15 is limited in the limiting groove, and switching of the protective layer 13 is facilitated.

When the utility model is used, the inner stay 9 is bent to support the mask body 1, the two ear hangers 8 are hung on ears respectively, the attaching strips 3 are attached to the face, the nose wing cushion 4 is pressed to adapt to the shape of the nose wing, and a relatively sealed protection cavity is formed between the mask body 1 and the nose and mouth of the face in the use process, so that the protection performance is improved; the anti-tearing performance of the side face of the mask body 1 is enhanced by the arrangement of the edge box 2.

Different protective layers 13 can be present in the interlayer according to different use scenes, and it should be noted that the smoke-proof layer 131, the haze-proof layer 132 and the activated carbon layer 133 are set to different colors, the activated carbon is black, and thus no extra treatment is needed, the smoke-proof layer 131 and the haze-proof layer 132 can be set to red or yellow respectively, due to the light transmittance of the mask body 1, the wearer can know the type of the used protective layer 13 in real time, and when the knob 7 is rotated to drive the soft rod 6 to continuously wrap around the protective layer 13 and switch the protective layer 13, the stopper 15 moves in the stopper groove until the required protective layer 13 corresponding to the type is completely located in the interlayer;

the utility model discloses set up grease proofing cigarette layer 131, antifog haze layer 132, activated carbon layer 133 in the intermediate layer respectively, make the person of wearing can switch according to the environment of the body, need not to carry the gauze mask of multiple classification and just can play good barrier propterty.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
