Description

Cover body for dust mask {Cover body for protection against dust mask}

The present invention relates to a cover for a dust mask that can replace the mask body, and in particular, equipped with a reverse dustproof function for the dust cover in the cover body to enable the assembly of the mask body manufactured to be replaced by a single-use manufacturing cost The dustproof mask cover body, which is integrally assembled and formed with reverse governing valve on the front side, is a mesh type, and injection molding synthetic resin, and the elastic band is hanged on the left and right edges of the cover body, It is possible to selectively tighten at the back of the head and to the left and right edges of the cover body to form a hook having a hook unit integrally relates to a dust mask cover body to enable elastic adjustment of the left and right bands as a locking support.

Dust masks are generally used in the production of dust, such as coal mines, quarries, weaving mills, paper mills, etc., where there are a lot of dust, dust, and foreign substances. Large amounts of toxic gases are produced in the working environment.

If such dust or toxic gas is continuously inhaled by workers, diseases such as lung diseases and respiratory diseases may occur due to industrial accidents, and if a large amount of dust or toxic gas is absorbed into the respiratory system or lungs due to continuous exposure. Since it can cause fatal harm to the human body, it is still wearing various kinds of dust masks to protect one's own health at work sites from harmful environment.

As a dust mask used for this purpose, a mask equipped with a purifying agent with a built-in gas mask or a filter with a built-in filter paper may be used, but most of these products are relatively expensive and may vary depending on the working time. However, after more than 10 hours, its function was deteriorated, so the gas masks had to be replaced and the filtration function was also reduced.

Pleated front part formed by bending the entire surface of the filter paper several times with a disposable dust mask, a hard finish of ultrasonic heat-sealed together with a hook band on both sides of the filter paper, and a metal wire formed on the top of the filter paper to be freely bent. Is provided, bends the metal wire to fit the contour of the user's face severely curved, as well as by spreading the wrinkles on the front of the filter paper evenly close to the wearer's nose and lower chin to increase the dust-proof efficiency dustproof The mask was created.

Hereinafter, the prior art will be described in more detail with reference to the accompanying drawings.

As a conventional sanitary mask, as shown in the drawing, two band hangers 20 are attached while forming a mask body 10 made of a sheet-like filter material made of fibrous material such as gauze or nonwoven fabric, similar to a hemispherical shape. By surrounding the nose, mouth and chin around the face of the mask body 30 was formed to be as close as possible. However, the conventional hygienic mask as described above has a problem that the edge of the mask body is not in close contact with the face due to the different face shape for each person.

In addition, the face shape of the wearer and the change of the nose height and the flexion form different forms, and the nose around the nose having the most change in the height and the width of the nose has more and more space between the face and the rim. There was a problem that the effect is significantly lowered.

In order to solve the above problems, the sponge is attached to the inner surface of the mask body around the nose as an adhesive member layer, and the adjusting member 40 of the metal wire formed of soft aluminum or the like on the outside of the mask body at the portion where the sponge is attached. By attaching the mask body to the face around the nose, mouth and chin with the upper and lower hanger straps, and bending the adjusting member to the nose shape of the mask wearer, the cushion cushion action of the sponge on the face around the nose. A mask was developed and used to make the sponge as close as possible.

However, as described above, the sponge is locally attached to only the portion of the inner surface of the mask body to be in contact with the nose, and the mask having an adjustment member that can be easily bent outside the mask body at the position where the sponge is attached is worn around the nose of the wearer. However, the space between the face and the mask can be prevented, but the inner surface of the mask body except for the portion to which the sponge is attached has large and small spaces depending on the shape of the face, which reduces the effect of wearing the mask. .

The hygienic masks and dust masks that are commonly used at present are all used on the mask body and the dust-proof exhaust metal wire ear, and the bands and supports that are filled on the back of the mask body are sold and used together with the mask body. After the afternoon (1 day), it was not possible to reuse it, so it was discarded as industrial garbage.

Particularly, in case of dust mask equipped with reverse governing valve used for dust and dust prevention in industrial sites where dust or powder is generated in large quantities, it is very costly to produce it and requires precision. Despite being able to be used again over time, there was a disadvantage in that expensive articles were discarded only because they were manufactured integrally with the mask body.

In order to solve such a problem, the applicant has been registered by submitting Utility Model Registration No. 389356,

Hemispherical mask body is provided with upper and lower hanger straps to be worn on the face, and a control member is provided on a part of the outer edge of the mask body to bend the adjusting member according to the wearer's nose shape. In a sanitary mask, the sanitary mask was configured to attach the cushion member directly to the entire inner surface near the edge of the mask body with an adhesive member layer so that the cushion member closely adheres to the wearer's face when the sanitary mask is worn. According to the above registration contents, the nose, mouth, and chin area of the hygiene mask wearer and the edges of the mask body are not only closely adhered to the face by the cushion filter, and therefore, the air that does not pass through the mask body and the cushion filter is nominated. Provide a hygienic mask to prevent breathing by mouth and mouth.

However, the above description has a problem that the adjustment of the band is not easy because the hook for the hook to the ear.

The present invention is intended to solve the above problems.

The mask body used for one-time use, the exhaust valve that exhausts air during breathing of the wearer, and the band fixing the mask body to the face are formed in a prefabricated manner. By removing only the mask body and replacing it with a new mask body, the expensive product is reused and only a mask body made of a nonwoven fabric or gauze fabric can be used.

In addition, the dust mask cover body of the present invention if the wearer adjusts the bending of the cover body according to the shape of the face or the height of the bend and fixed the elasticity of the band immediately wear it by a simple separation replacement only the mask body There is also an advantage that can come.

As a means for achieving the above object,

The present invention is integrally injection-molded the body of the reverse displacement to free the exhaust by the one-way reverse displacement by the one-way reverse displacement to the front surface of the mesh-type mask cover body manufactured by injection molding synthetic resin and the front surface of the rubber thin film It is assembled and secured by the cover, and it is provided with an extension part inside the reverse displacement main body, and is assembled and installed with an inner coupling member while being inserted into the extension part through a central hole of a mask body made of a hemispherical cam shape. .

The mask body to be assembled to the mask cover body is made by pressing and fixing a nonwoven fabric or a cotton fiber.

In addition, the left and right sides of the mask assembly, the hook body that can be adjusted to hang the hook band to the upper and lower hook portion formed integrally to be used to hang the band while the mask body is coupled to the central reverse side The mask cover body is roughly shaped like a hemispherical cap, and is closely attached to the band so that the rim is in close contact with the face of the wearer's nose, mouth, and chin, and the dustproof effect can be increased, and the mask body used once is replaced with a new one. It can be used to provide the effect of cost reduction.

As described above, the present invention provides a dust mask cover body manufactured by injection molding a synthetic resin, having a reverse governing edge on the front side, and having a hook hole for hanging a hook band on both sides of the rim, thereby forming a hook portion in a groove shape. Release the band lock support to adjust the elasticity of the band.

In the present invention, the part discarded after use by the wearer is inserted into the inner extension of the central reverse governing edge of the mesh cover body in the entire dust mask and separates and removes only the mask body that is fixedly installed with the coupling member, and the reverse governing edge. This mesh-type dust mask cover can be used again, minimizing consumer expenses by reusing expensive cover products and disposing only hemispherical mask body produced by pressing nonwoven fabric or gauze or fiber. It can work.

In addition, since both sides of the hanger formed on both sides of the mesh mask cover body of the present invention to be able to hang the headband as a locking support (not shown) is provided with a hook-shaped hook portion when the band is to be tightened more The band is inserted into the grooves on both sides of the hook is pulled into the central gutter, and thus the mask cover body is pulled a little more, so that the mask body is more closely attached to the face.
