Abstract

The invention relates to a dustproof mask which has a filter on the inner side of a suction fan so that the direct jet of the inhaled air about the mouth and nose of a wearer can be minimized, and which forms an emission hole corresponding to the mouth of the wearer so that the internal air is forcedly emitted through the emission hole, thereby enabling the wearer's action of emitting air to be performed stably and easily and enabling the speech of the wearer to be smoothly delivered to the outside. The present dustproof mask comprises: a mask body (10) having an emission hole (11) and intake holes (12); a pair of suction fans (20) installed on the outer surface of the mask body (10) to correspond to the intake holes (12); a filter (30) installed on the inner surface of the mask body (10) to correspond to the suction holes (12); a clamping band (40) of which both ends are connected to both sides of the mask body (10); a battery (50) mounted on the clamping band (40); and an on/off switch (60) installed at the clamping band (40).

Description

Dust mask

The present invention relates to a dust mask, and more particularly, having a filter inside the suction fan to minimize the direct injection of the suction air to the wearer's mouth and nose and to form a discharge hole corresponding to the wearer's mouth The present invention relates to an anti-vibration mask that makes the act of spitting the wearer's air as it is forced to release the air through the ball, stably and easily, and allows the wearer's speech to be smoothly transmitted to the outside.

In general, dust masks come into the respiratory tract with a large amount of harmful dust generated by workers in various industrial sites such as paper mills, textile mills, quarries, or metal processing plants such as chemical plants and weld plating. Used to prevent losing.

These dust masks have become a major item that is used not only by the workers on the job site but also by the general public due to the recent extreme dust and yellow dust.

The general structure of the anti-vibration mask includes a mask body having a non-woven fabric and an electrostatic filter and having a hemispherical curved structure to wrap around the mouth and nose of the worker, and a band which is a means for fixing the mask body to the face of the worker. It is composed.

That is, when the worker inhales the air while wearing the dust mask, the outside air is introduced through the intake port formed in front of the mask body, and the introduced air is introduced into the inner space of the mask body with the foreign matter filtered through the filter. Afterwards, it is transmitted to the worker's respiratory system, in which air must be generated in such a large amount of suction to pass through a plurality of filters, which has a disadvantage of exerting a lot of pressure on the worker's respiration.

In order to alleviate this drawback, a dust mask has been proposed that includes a suction fan driven by a motor at the rear of the filter to forcibly suck outside air and spray the inside air.

However, the above conventional technologies have the following problems.

In the conventional forced suction dust mask, the air passing through the filter is sprayed from the inside of the mask body toward the wearer's mouth and nose, which is easy for the wearer to inhale air, but spits the wearer's air by the air injected by the suction fan. The act of giving, that is, the act of exhaling, is very inconvenient, and there is a problem in that it does not maintain proper breathing while the inconvenience of use remains.

In addition, the conventional anti-vibration mask is provided in a form surrounding the wearer's mouth to close when there is a inconvenience in use, such as the speech is not properly transmitted to the outside when the wearer speaks.

Accordingly, the present invention has been made to solve the conventional problems as described above,

An object of the present invention is to provide a filter inside the suction fan to minimize the direct injection of the suction air to the wearer's mouth and nose and to form a discharge hole corresponding to the wearer's mouth to force the internal air through the discharge hole It is to provide a dustproof mask that makes the act of spitting the air of the wearer while being released is stable and easy, and the sound of the wearer can be smoothly transmitted to the outside.

In order to achieve the above object, the "dust-proof mask" according to the present invention is formed in a hemispherical curved structure so as to wrap around the mouth and nose of the wearer, the discharge hole is formed corresponding to the wearer's mouth, the discharge hole A pair of suction holes are formed to penetrate both sides of the mask body, and the air sucked into the interior from both sides through the suction holes is guided forward with the breath of the wearer to be discharged to the outside through the regular discharge holes; A pair of suction fans installed on the outer surface of the mask body corresponding to the front surface of each suction hole, and driven by the supply of power to suck outside air and spray the inside of the mask body through the suction hole. and; A pair of filters installed on an inner surface of the mask body corresponding to the rear surface of each suction hole and filtering foreign substances contained in the outside air introduced through the suction fan; Fixed bands fixed at both ends of the mask body to fix the mask body to a wearer's face; It is characterized by including.
