Yellow dust mask for antifogging of glasses {yellow dust mask for antifogging of glasses}

The present invention relates to a yellow dust mask, and more particularly, a yellow dust mask for preventing fogging of glasses that can prevent the user's glasses from fogging as the user's breathing is smooth as well as inhaling and blocking ultrafine dust smoothly. is about

Air pollution is becoming serious due to dust emission from large-scale industrial facilities.

Accordingly, various laws and regulations have been enacted to limit the emission of air pollutants, but contrary to expectations, air pollution is gradually worsening.

Meanwhile, ultrafine dust is one of the air pollutants.

Ultrafine dust, which has a diameter of 2.5 μm or less, is significantly insignificant compared to fine dust with a diameter of 10 μm or less and penetrates deeply into the alveoli of the human body, and is a major cause of various respiratory diseases.

For this reason, the majority of the population refrains from going out on days when the concentration of ultrafine dust is high, and when going out, personal equipment such as a mask is worn to minimize inhalation of ultrafine dust.

At this time, a general mask made of textile fabric, etc., could not block the inhalation of ultrafine dust, so a yellow dust mask (' Also called a 'mask for ultrafine dust') is being used.

In the yellow dust mask, a filter for filtering ultrafine dust is provided on the inner surface (the side facing the user's face in the worn state) of the outer fabric, which is freely ventilated, so that suction of the ultrafine dust can be blocked by wearing it.

However, the filter of the yellow dust mask interferes with the exhalation of breath when the user breathes, and as some of the breath that did not pass through the filter flows upward through the gap between the yellow dust mask and the face, the user's glasses become foggy, so the user's glasses are secured. There was a problem that made it difficult.

For this reason, consumers are demanding a yellow dust mask that not only blocks the inhalation of ultrafine dust, but also prevents the user's glasses from fogging up as the user's breathing is smooth. it cannot be seen.

And since the outer fabric 10 is formed to be wrinkled with a difference in height, the height is expanded as the wrinkled portion is unfolded, so that it can completely cover the user's face part, more specifically, around the mouth and nose.

On the other hand, the outer fabric 10 may be any type of conventional fabric as long as it is a fabric with free ventilation, and for example, it may be a woven fabric or a non-woven fabric.

The filter 20 of the present invention is provided on the inner surface of the outer fabric 10 to filter ultra-fine dust.

Accordingly, the inhalation of ultrafine dust is blocked by the filtering in the filter 20 .

At this time, the filter 20, the first filter 21 disposed on the inner surface side of the outer fabric 10; and a second filter 22 disposed on the inner surface side of the first filter 21 .

Accordingly, ultrafine dust filtering may be performed in each of the first filter 21 and the second filter 22 .

Here, the first filter 21 and the second filter 22 are provided with a plurality of through-holes 21a and 22a arranged at intervals, but the through-holes 21a of the first filter 21 and the second filter 22 ) of the through hole (22a) is arranged so as not to overlap.

Therefore, when the first filter 21 and the second filter 22 are in close contact with each other, the opening of each through-hole 21a, 22a is blocked, and when the first filter 21 and the second filter 22 are spaced apart from each other, each The through holes 21a and 22a are fully opened.

On the other hand, since the first filter 21 and the second filter 22 may be of any general type as long as they can filter ultrafine dust, detailed information regarding the first filter 21 and the second filter 22 is provided. A description is omitted.

And the first filter 21 and the second filter 22 have their edges sewn along the edge of the outer fabric 10 to separate the outer fabric 10 , the first filter 21 and the second filter 22 . is prevented

In addition, the yellow dust mask (A) for preventing fogging of glasses according to the present invention may further include an inner fabric 30 made of a fabric free of ventilation on the inner side of the second filter 22 as shown in FIG. 4 . there is.

Since the inner fabric 30 is the same as the outer fabric 10 only to block the exposure of the filter 20 , a detailed description of the inner fabric 30 will be omitted.

In addition, the filter 20 is additionally disposed on the outer surface side of the first filter 21 to filter the ultrafine dust contained in the outdoor air, but a third type different from the first filter 21 and the second filter 22 . A filter 23 may be further included.

At this time, the third filter 23 has a height lower than that of the first filter 21 , so that outdoor air inflow and user's breath discharge can be free through the upper or lower side of the third filter 23 .

The use of the yellow dust mask (A) for preventing fogging of glasses according to the present invention will be described in detail as follows.

As shown in FIG. 1, the yellow dust mask (A) for anti-fogging glasses according to the present invention is worn on the user's face and covers the mouth and nose.

At this time, a filter 20 for filtering ultrafine dust is provided on the inner surface side of the outer fabric 10, and the external air introduced by the user's breathing passes through the outer fabric 10, which is freely ventilated, and reaches the filter 20. Because it is filtered, the inhalation of ultrafine dust through the user's mouth and nose is blocked.

However, since the filter 20 interferes with the exhalation of breath by the user's respiration, when a portion of the user's breath that does not pass through the filter 20 flows upward through the gap between the inner fabric 30 and the user's face, the user's glasses ( There may be fogging in the reference numerals not shown).

However, in the present invention, the filter 20, the first filter 21 disposed on the inner surface side of the outer fabric 10; and a second filter 22 disposed on the inner surface side of the first filter 21 , wherein the first filter 21 and the second filter 22 have a plurality of through holes 21a and 22a disposed at intervals. ), and the through-hole 21a of the first filter 21 and the through-hole 22a of the second filter 22 are arranged not to overlap each other, and the breath discharged by the user's respiration is the first filter 21 And as it flows through the through holes (21a, 22a) provided in the second filter (22), it easily passes through the first filter (21) and the second filter (22), so that the user's breath can be discharged smoothly, so that the user's glasses Fogging can be prevented.

That is, the first filter 21 and the second filter 22 are inflated to the outside and spaced apart from each other in the process of exhaling the breath by the user's respiration, as shown in FIG. 3 , the first filter 21 and the second filter Since the through-hole 21a of the first filter 21 and the through-hole 22a of the second filter 22 are completely opened by the mutual spacing of (22), the through-hole 22a of the second filter 22 that is completely open hidden by the user ) to easily flow toward the first filter 21, and easily flow toward the outer fabric 10 through the through hole 21a of the first filter 21, which is completely open to the user who has reached the first filter 21. Since it is easily leaked to the outside through the free-ventilated outer fabric 10, the user's breath can be smoothly discharged, thereby preventing fogging of the user's glasses.

At this time, the inflow of outside air through the through-holes (21a, 22a) of the first filter 21 and the second filter 22 that are spaced apart from each other in the user's breath discharge process may be concerned.

However, as shown in FIG. 2 , the first filter 21 and the second filter 22 are inwardly closed and in close contact with each other during the inflow of external air by the user's respiration, the first filter 21 and the second filter Since the opening of each of the through-holes 21a and 22a is blocked by the close contact of 22, the inflow of outside air through the through-holes 21a and 22a can be prevented, so that the first filter 21 and the second filter 22 are mutually connected. After the separation, the ultrafine dust contained in the outdoor air may be filtered by the first filter 21 and the second filter 22 .

Since the present invention as described above is not limited to the above-described embodiments, it can be changed within the scope without departing from the gist of the present invention claimed in the claims, and such changes are the present invention defined by the following claims. fall within the protection scope of the invention.
