Description

Filter replacement MASK PAD

The present invention relates to a filter replacement mask pad, and more specifically, a one-time mask can be reused by inserting a mask pad with a built-in electrostatic filter into the inner surface of the mask body to be detachably inserted. It relates to a filter replacement mask pad that can filter fine dust, viruses, and various harmful bacteria.

Recently, the amount of fine dust flowing into Korea is increasing due to the increase in combustion of fossil fuels due to China's industrialization along with fine dust. It is also getting serious.

Fine dust contains a large amount of toxic compounds and heavy metals, and is known to cause diseases such as heart attack, asthma, bronchitis, pneumonia, and lung cancer when inhaled by humans. According to one study, there is also a report that about 20,000 premature deaths and lung-related diseases occur annually due to fine dust in the metropolitan area alone. Masks are frequently used to block such fine dust from entering the human body.

The mask prevents outside air from flowing into the mask body covering the wearer's nose and periphery, and the ear hook provided as a means for fastening the mask to the wearer and the back of the nose. It is composed of a nose for The mask body of a mask used for blocking fine dust includes an electrostatic filter capable of blocking fine dust, and is generally formed integrally with the electrostatic filter.

However, if the electrostatic filter is worn for more than a certain period of time, the pores of the filter are clogged, making it difficult to breathe. And there is a problem in that the inside of the mask is moistened by the wearer's breath and bacteria are propagated.

Accordingly, the present invention provides a filter replacement mask pad in which a mask pad having a built-in electrostatic filter is detachably inserted into the inner surface of the mask body so that the disposable mask can be reused.

In addition, it provides a filter replacement mask pad that can filter fine dust, viruses, and various harmful bacteria by making the thickness of the electrostatic filter between 12g and 40g.

The core configuration of the present invention that can achieve the above object is in the filter replacement mask pad. It is composed of first and second filter papers and filter paper attached to each other in a state of being sandwiched between the first and second filter papers. It is characterized in that it is detachably installed on the inner surface of the body.

The present invention has the effect of reusing a one-time mask only by replacing only the pad with a new one by detachably installing the triple-structured filter replacement mask pad on the inner surface of the mask body that is covered on the wearer's face.

In addition, by making the thickness of the electrostatic filter between 12g and 40g, it can effectively filter fine dust, viruses, and various harmful bacteria.

1 is a three-dimensional view showing the configuration of a filter replacement mask pad detachably inserted into a mask according to the present invention, FIG. 2 is a view showing a cross section of FIG. 1, and FIG. It is a flat view.

1, 2, 3, the mask consists of a mask body 10 and a hanging string (20).

The mask body 10 is made of a fabric having elasticity so that it can be elastically adhered to the curved shape of the wearer's face, and is made of a size sufficient to cover the entire nose and mouth from the wearer's face.

The hanging string 20 is formed on both sides of the mask body 10, is hung on the wearer's ear, and fixes the mask body 10 to the face.

A filter replacement mask pad 30 is detachably installed on the inner surface of the mask body 10 .

The filter replacement mask pad 30 is a pad that filters fine dust or various harmful bacteria that are sucked through the mask body 10 in the breathing process and blocks the inflow into the human body.

The filter replacement mask pad 30 has a triple structure, and consists of first and second filter papers 32 and 34 and a filter paper 40 inserted between the first and second filter papers 32 and 34 . .

It is preferable that the first and second filter papers 32 and 34 are made of polypropylene (PP) having a certain amount of filtering function without causing skin trouble considering that they can directly contact the wearer's skin. .

As the filter paper 40, it is preferable to use an electrostatic filter to adsorb fine particles and dust in the air because the filter has static electricity. These static filters filter out smoke or fine dust that cannot be filtered out by normal filters. In addition, the filter paper 40 can be replaced with a nanofiber filter if necessary.

The thickness of the filter paper 40 is preferably made between 12 g and 40 g, and this is to ensure that the filter paper has a certain thickness to effectively filter out fine dust, viruses, and various harmful bacteria. In fact, when the thickness of the filter paper 40 was produced between 12 g and 40 g, it was confirmed that the optimal filter effect was realized. In the case of 40 g or more, there was a problem of inconvenient breathing due to the long permeation time of air.

In addition, it is preferable that the first and second filter papers 32 and 34 also have a thickness between 12g and 40g in the same way as the filter paper 40 .

The filter replacement mask pad 30 having a triple structure of the first and second filter papers 32 and 34 and the filter paper 40 is manufactured by the following method.

First, the first and second filter papers 32 and 34 and the filter paper 40 are cut according to the size of the mask body 10 . At this time, the cut shape has various shapes on a plane, for example, it may be manufactured in a shape such as a square, an oval, a diamond shape, or a circle shape.

In addition, the cutting size is preferably cut to various sizes between 50 mm to 250 mm in the horizontal direction, 30 mm to 150 mm in the vertical direction, and 0.05 mm to 0.5 mm in thickness.

Next, after sequentially stacking the cut first filter paper 32, filter paper 40, and second filter paper 34, ultrasonic bonding 36 is carried out along the periphery. At this time, before performing the ultrasonic bonding 36, the metal nose piece 42 may be inserted between the first filter paper 32 and the filter paper 40, and then ultrasonic bonding may be performed.

Next, the first filter paper (32) is manufactured by attaching a double-sided tape (50) on and below the outer surface of the filter paper (32). In this case, the double-sided tape 50 may be attached over the entire upper and lower outer surfaces of the first filter paper 32, and may be manufactured by partially attaching to the outer surface of the first filter paper 32 if necessary.

The filter replacement mask pad 30 manufactured as described above can be used by being attached to the inner surface of the mask body 10 using a double-sided tape 50 as shown in FIG. 4, or as shown in FIG. 5, the mask body ( 10), a pocket 60 is formed on the inner surface, and a mask pad 30 for replacing the filter is inserted into the pocket 60 to be used.

The mask in which the filter replacement mask pad 30 of the present invention is inserted can effectively filter fine dust, viruses, and various harmful bacteria through a triple filter structure when worn, and the filter replacement mask pad ( 30) can be reused only by replacing it with a new one, increasing practicality and dramatically reducing unnecessary resource waste.
