These harmful substances are a major factor that hinders the health of workers, and a dustproof mask or gas mask has been developed as a means to control this.

Here, the dustproof mask or the respiratory mask (hereinafter, referred to as a mask) is generally divided into a face portion and a purifier, and a filter is provided in the purifier to purify the air. In particular, the masks are manufactured in various forms, such as a small-sized, one-size-fits-a-mask that covers only the nose and mouth, and a face mask that covers the entire face. Such a mask should have sufficient visibility to the wearer so as not to interfere with the operation, and it is advantageous in terms of cost reduction as the replacement period of the canister is longer.

However, the mask according to the prior art is provided on one side or both sides of the portion where the wearer's mouth is located, as disclosed in the patent documents of the following prior art documents. Therefore, there is a problem that the purifying column of the mask narrows the field of view of the wearer, thereby interfering with the work. In addition, since the purifier is located on the front surface of the mask, minute substances such as dust generated by the operation are directly absorbed into the purifier. As a result, there is a problem in that the replacement period of the purifier is shortened and the replacement cost is excessively consumed.

[

The cover 110 is in contact with the respiratory organ of the wearer and serves to supply air purified by the filter 130 to the wearer. Here, the rim of the cover 110 should be completely in contact with the wearer's face so that foreign bacteria, fine dust, water and the like are prevented from entering the wearer's face. For this purpose, the cover 110 may be fixed to the wearer's face with a fixing strap 113 provided on both sides. When the user wears the air in the state that the cover part 110 is fixed to the wearer's face, the pressure inside the cover part 110 becomes lower than the atmospheric pressure of the outside, so that the cover part 110 is more closely attached to the wearer's face , It can be completely cut off from the outside. Meanwhile, the cover 110 may have intake holes 115 on both sides thereof to suck air purified by the filter 130. Here, the intake hole 115 receives purified air from the filter unit 130 through the connection hose 140, and a detailed description will be given later. In addition, the cover 110 may include an exhaust valve 117 at the center so that the air discharged from the wearer can be discharged to the outside. Here, the exhaust valve 117 is provided with an exhaust film formed of rubber so as to discharge the air exhaled by the wearer to the outside, but to prevent the inflow of air from the outside. In the meantime, the cover 110 in the drawing is a small-size, but type mask that accommodates the wearer's mouth and nose, but is not limited thereto, and may be a face mask with a lens provided so as to cover the entire face, Lt; / RTI >
