Description

Multi Functional Mask < RTI ID = 0.0 >

The present invention relates to a multifunction mask.

With rapid industrial development, the industrial structure has become more complicated and the size and number of operators have increased, so that various hazardous substances have been used or handled. 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. On the other hand, the conventional mask has a problem that moisture is generated in the lens by the temperature difference between the inside of the lens and the outside of the lens, but there is no means for removing the moisture of such a lens.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A through 1C are perspective views of a multifunction mask according to an embodiment of the present invention.

As shown in FIGS. 1A to 1C, the multi-function mask according to the present embodiment includes a protection lens 113 for covering a wearer's eye and securing a field of view, and an upper mask (not shown) having a suction hole 115 formed on one side thereof A first check valve 123 provided at a lower end of the upper mask 110 to cover the wearer's nose and mouth and to communicate with the upper mask 110 and a second check valve 125 communicated with the outside, The first check valve 123 can pass gas only in the direction of the lower mask 120 from the upper mask 110 and the second check valve 125 can pass through the lower mask 120 in the direction of the gas The gas introduced into the upper mask 110 through the suction holes 115 is transmitted to the lower mask 120 through the first check valve 123 so that the wearer And the gas exiting the nose or mouth of the wearer is sucked into the nose or mouth of the second check valve 125 It is discharged to the outside.

The upper mask 110 protects the wearer's eyes. Here, the upper mask 110 is provided with a protective lens 113 on its front surface. The protective lens 113 covers the eyes of the wearer and can be formed of a transparent material to ensure a visual field. Further, a suction hole 115 is formed on one side of the upper mask 110. Here, the suction hole 115 may be formed at the upper end of the upper mask 110 (see FIG. 1A) or at the side end (see FIG. 1B). However, the suction hole 115 is not necessarily formed at either the upper end or the upper end of the upper mask 110, but may be formed at both the upper end and the side end of the upper mask 110 (see FIG. At this time, a stopper 117 may be provided to selectively close the suction hole 115. The cleaned gas or an external gas may be introduced into the upper mask 110 through the suction hole 115. Particularly, when air is sucked into the wearer's nose or mouth, air can be prevented from flowing into the upper mask 110 through the suction hole 115, thereby generating moisture in the protective lens 113, Details related to this will be described later.

The lower mask 120 supplies a gas or an external gas purified from the filter unit to the nose or mouth of the wearer and discharges the gas discharged from the nose or mouth of the wearer to the outside. Here, the lower mask 120 is provided at the lower end of the upper mask 110 to cover the wearer's nose and mouth. At this time, the lower mask 120 may be formed integrally with the upper mask 110, and the dividing film 127 may be formed at the boundary between the lower mask 120 and the upper mask 110. However, the lower mask 120 is not necessarily formed integrally with the upper mask 110, but may be separately fabricated and coupled. Also, the lower mask 120 and the upper mask 110 are provided with a packing which is in close contact with the wearer's face, thereby preventing inflow of bacteria, fine dust, water, etc. from the outside. The lower mask 120 may include a first check valve 123 communicating with the upper mask 110 and a second check valve 125 communicating with the upper mask 110. Here, the first check valve 123 can pass the gas only from the upper mask 110 toward the lower mask 120, and can not pass from the lower mask 120 toward the upper mask 110. The gas introduced into the upper mask 110 through the suction holes 115 can be transferred to the lower mask 120 through the first check valve 123 and sucked into the wearer's nose or mouth. At this time, since a new gas continuously flows into the upper mask 110 through the suction hole 115, the temperature difference between the inside of the protective lens 113 and the outside of the protective lens 113 is reduced, It is possible to prevent the moisture from being generated in the water tank 113. Also, the second check valve 125 can only pass the gas in the outward direction from the lower mask 120, and can not pass from the outside toward the lower mask 120. Therefore, the gas discharged from the wearer's nose or mouth is discharged to the outside through the second check valve 125, and is not discharged toward the upper mask 110. As a result, it is possible to prevent moisture from being generated in the protective lens 113 of the upper mask 110 by the gas discharged from the wearer's nose or mouth.

More specifically, the lower mask 120 may include a first lower mask 120a configured to cover a wearer's mouth and a second lower mask 120b configured to cover a wearer's nose. Here, the second lower mask 120b may extend upward from the central region of the upper end of the first lower mask 120a so as to have a width corresponding to the nose of the wearer's nose.

When the lower mask 120 is composed of the first lower mask 120a and the second lower mask 120b as described above, the first check valve 123 is disposed on the upper surface of the first lower mask 120a 110) or the second lower mask 120b. Further, the second check valve 125 may be formed on the lower surface or the front surface of the first lower mask 120a. However, the positions of the first check valve 123 and the second check valve 125 described above are illustrative and not necessarily limited thereto. The type of the first check valve 123 and the second check valve 125 is not particularly limited. As shown in the enlarged view of FIG. 1A, the first check valve 123 and the second check valve 125 are provided with a panel 126a having an opening, And a check member 126b fixed to one side of the panel 126a. Due to the panel 126a and the check member 126b, when the pressure is applied in one direction, the check member 126b is bent and the gas passes through the panel 126a and the pressure in the other direction The check member 126b can close the panel 126a to prevent the gas from passing therethrough.

The air in the upper mask 110 is transferred to the lower mask 120 and new air is supplied to the upper mask 110 through the suction holes 115. Therefore, whenever the wearer sucks air, the air continues to flow into the upper mask 110, and the temperature difference between the inside and the outside of the protective lens 113 decreases, so that moisture is generated in the protective lens 113 Can be prevented. Since the second check valve 125 can pass air only in the outward direction from the lower mask 120 and can not pass from the outside toward the lower mask 120, Even if air is sucked into the nose or mouth, external air is not directly supplied to the lower mask 120 through the second check valve 125.

Next, as shown in FIG. 3, when the wearer wears the multifunctional mask, air is discharged to the nose or mouth covered with the lower mask 120, and the air is discharged through the second check valve 125 to the lower mask 120 The air is exhausted to the outside. Since the first check valve 123 can pass air only in the direction of the lower mask 120 from the upper mask 110 and can not pass in the direction of the upper mask 110 from the lower mask 120, Even if air is discharged through the nose or mouth covered with the lower mask 120, air discharged into the nose or mouth is not transferred to the upper mask 110. [ Therefore, it is possible to prevent moisture from being generated in the protection lens 113 of the upper mask 110 by air discharged from the nose and mouth.
