Description

Dust mask using static electricity {DUST FILTER MASK USING STATIC ELECTRICITY}

The present invention relates to a dust mask, and to a dust mask for filtering dust using static electricity.

In order to prevent damage from fine dust that continues in recent years, the use of dust masks is increasing regardless of the season, which has significantly expanded the mask market.

Currently, most dust masks are made of mainly textile materials to filter dust or dust, and the fiber density of the filter is increased to increase filtering performance. In addition, in the case of some high-performance masks, various chemical and physical additional filters are further included to improve filter performance. However, if the density of the filter is increased or an additional filter is installed to improve the filter performance, there is a problem that the user's breathing is not smooth.

Even in the case of a general mask, since users tend to feel uncomfortable wearing the mask when worn, there is a problem in that they avoid using the mask even more if breathing is not smooth.

In order to solve the problem that the user's breathing becomes difficult due to the mask wearing due to the improvement of the filtering performance of the mask, a mask that can filter dust using static electricity rather than chemical or physical method has recently been developed. has been proposed

However, in conventional dust masks using static electricity, since electrodes are formed in a horizontal or vertical grid structure, dust may not be filtered according to grid spacing. In addition, the mask is easily subjected to impact or pressure from the outside during use, and this has a problem in that the filtering performance may be deteriorated as the spacing between the gratings is changed. In addition, since most permanent electrostatic filters are used, they are vulnerable to moisture, such as breath, and are difficult to reuse because they cannot be washed or washed.

1 shows a structure of a dust mask into which a dust filter using static electricity is inserted according to an embodiment of the present invention.

Referring to FIG. 1 , the dust mask according to the present embodiment may include a mask outer skin 110 , a mask inner skin 120 , a wearing strap 130 , and a dust filter 200 .

The mask shell 110 forms an outer surface of the mask to protect the mask from external impact or damage. The mask shell 110 may be implemented with various materials, for example, may be implemented with a soft material such as a non-woven fabric or cotton, or may be implemented with a hard hard material. In some cases, the mask shell 110 may be implemented with a soft material and a hard cover may be added to the outer surface. In addition, the mask shell 110 may also serve as an external filter that preferentially filters dust introduced from the outside according to the material implemented.

The mask endothelium 120 is a part in direct contact with the wearer's skin and improves the wearer's fit. And the mask endothelium 120 may also serve as an internal filter that finally blocks the dust introduced from the outside.

The wearing strap 130 is coupled to the mask outer shell 110 or the endothelium 120, and is hung on the wearer's ear when the wearer wears the mask, so that the mask is stably fixed to the wearer. The wearing strap 130 is made of a material having elasticity so that a space is created between the contact position of the mask and the user's skin, and dust is prevented from entering the inside without going through the filter so that the mask can be in close contact with the wearer. have.

The dust filter 200 is implemented in the form of a thin film and is disposed between the mask shell 110 and the endothelium 120 to filter dust introduced into the inside through the mask shell 110 . That is, the dust filter 200 is disposed parallel to the mask outer shell 110 and the inner shell 120 in a vertical direction in a direction in which air is introduced from the outside of the dust mask. And in this embodiment, the dust filter 200 has first and second electrode surfaces, and collects dust by applying a predetermined high voltage between the first and second electrode surfaces to generate static electricity. In general, since dust has a positive charge component, when static electricity is generated between the first and second electrode surfaces, it is guided to the electrode surface having a negative charge among the first and second electrode surfaces and is collected.

A detailed configuration of the dust filter 200 will be described later.

The dust filter 200 may be implemented in the form of a thin film and inserted between the mask outer shell 110 and the endothelium 120 . In this embodiment, the outer shell 110 and the endothelium 120 may be implemented such that the edges except for some regions are coupled so that the dust filter 200 is inserted therein. In addition, in some cases, a coupling means such as Velcro is attached to the entire edge of the mask shell 110 and the endothelium 120, so that the mask shell 110 and the endothelium 120 are easily coupled and separated. A dust filter may be inserted and fixed between the mask outer skin 110 and the inner skin 120 . This is to facilitate washing and washing by allowing the electric circuit to be separated from the dust mask using static electricity as in the present embodiment.

FIG. 2 shows a schematic configuration of the dust filter of FIG. 1 .

Referring to FIG. 2 , the dust filter 200 according to the present embodiment may include a battery 210 , a power circuit unit 220 , and a mask electrode unit 230 .

The battery 210 supplies power so that the dust filter 200 can generate static electricity. The battery 210 may be, for example, a replaceable battery or a rechargeable battery so that the dust filter 200 can be reused.

The power circuit unit 220 converts the power supplied from the battery 210 into a high voltage and low current signal that is easy to generate static electricity. The power circuit unit 220 receives the power conversion unit 221 for converting the DC power supplied from the battery 210 into an AC signal having a predetermined voltage level, and the AC signal, amplifies and rectifies. and a voltage amplifying unit 222 for generating a DC high voltage and low current signal for generating static electricity.

Here, the power circuit unit 220 converts the DC power supplied from the battery 210 into an AC signal and then amplifies and rectifies it because it is easy to obtain a DC high voltage and low current signal required to generate static electricity. However, the power circuit unit 220 of the present embodiment is not limited thereto, and may be implemented with various circuits capable of obtaining a high voltage and low current signal from the DC power supplied from the battery 210 .

The mask electrode unit 230 generates static electricity according to the high voltage and low current signal applied from the power circuit unit 220 to collect dust introduced into the mask. The mask electrode unit 230 includes a first electrode surface to which a first voltage of the DC high voltage and low current signal generated by the power circuit unit 220 is applied, a second electrode surface to which a second voltage is applied, a first electrode surface, and a second electrode surface. It may include a filler disposed between the electrode surfaces. Here, the filler maintains a predetermined distance between the first electrode surface and the second electrode surface so that static electricity is generated between the first electrode surface and the second electrode surface. That is, the first electrode surface and the second electrode surface are spaced apart with a filler interposed therebetween to generate static electricity, so that dust is collected on at least one of the first electrode surface and the second electrode surface. In general, since dust has a positively charged component, it may be collected on the negatively charged electrode surface among the first electrode surface and the second electrode surface.

On the other hand, in the present embodiment, a plurality of ventilation holes are formed on the first electrode surface and the second electrode surface to be displaced from each other according to a predetermined pattern, so that the mask wearer can keep breathing smoothly while efficiently removing the dust introduced into the mask. so that it can be captured by

Hereinafter, the structure of the mask electrode part 230 according to the present embodiment will be described in detail.

3 and 4 show the disassembly and coupling of the dust filter according to the present embodiment, and FIG. 5 shows a process in which dust introduced into the dust filter of FIG. 4 is filtered.

3 and 4 , the first electrode surface 310 and the second electrode surface 320 of the dust filter are disposed parallel to each other, and between the first electrode surface 310 and the second electrode surface 320 . The filler 330 is disposed. Since the dust filter is disposed in a direction perpendicular to the direction in which air flows from the dust mask, the first electrode surface 310 , the second electrode surface 320 , and the filler 330 are also disposed in a direction perpendicular to the air inflow direction. .

In addition, on the first electrode surface 310 and the second electrode surface 320 , a first voltage (a positive (+) voltage as an example) and a second voltage (here, an example) of the high voltage and low current signal generated by the power circuit unit 220 . negative (-) voltage) is applied respectively. Here, the first electrode surface 310 and the second electrode surface 320 may be formed of, for example, a thin-film conductor such as carbon or aluminum.

Meanwhile, a plurality of ventilation holes 311 and 321 are formed in each of the first electrode surface 310 and the second electrode surface 320 so that air can be smoothly introduced into the mask. However, in this embodiment, the plurality of first ventilation holes 311 formed on the first electrode surface 310 and the plurality of second ventilation holes 321 formed on the second electrode surface 320 have overlapping regions. formed so that it does not occur.

For example, in FIGS. 3 and 4 , a plurality of second ventilation holes 321 formed on the second electrode surface 320 correspond to between the plurality of first ventilation holes 311 formed on the first electrode surface 310 . placed in position This is to prevent dust introduced together with air through the first ventilation hole 311 from directly reaching the wearer without passing through the second electrode surface 320 .

If a region is generated in which the plurality of first ventilation holes 311 formed on the first electrode surface 310 and the plurality of second ventilation holes 321 formed on the second electrode surface 320 overlap each other, The dust introduced into the dust filter 200 from the outside passes through it without being collected and may be directly delivered to the wearer. Although a high voltage and low current signal is applied to the first and second electrode surfaces 310 and 320 and the dust introduced is induced to one of the first and second electrode surfaces 310 and 320 by static electricity, the mask wearer breathes, and when the wearer's breathing strength is strong, the dust may pass through the dust filter without being collected and directly delivered to the wearer. This means that the dust mask cannot perform the required function.

Accordingly, in the present embodiment, as shown in FIG. 5 , the plurality of second ventilation holes 321 are formed so as not to overlap the plurality of first ventilation holes 311 , so that the dust introduced with air must be first or to be collected on at least one of the second electrode surfaces 310 and 320 . In particular, even if the wearer's breathing strength becomes stronger, air does not directly permeate, and the space formed between the first electrode surface 310 and the second electrode surface 320, that is, the space in which the filler 330 is disposed. By passing in the lateral direction, the dust introduced with the air is collected very effectively.

The power circuit unit 220 may be configured to apply a negative voltage to the first electrode surface 310 and a positive voltage to the second electrode surface 320 , but since dust has a positive charge, as shown in FIG. Similarly, when a negative voltage is applied to the second electrode surface 320 , dust introduced into the interior through the first electrode surface 310 can be more efficiently collected. In addition, since the first electrode surface 310 has the same polarity as the dust, a repulsive force is generated, thereby reducing the amount of dust primarily introduced into the dust filter.

As described above, the filler 330 is disposed between the first electrode surface 310 and the second electrode surface 320 such that the first electrode surface 310 and the second electrode surface 320 maintain a predetermined distance. Ensure that the electric field is stably formed. Here, the filler may be formed of, for example, a nonwoven fabric, and not only prevent the first electrode surface 310 and the second electrode surface 320 from being shorted, but also the first electrode surface 310 and the second electrode. The movement speed of the dust introduced between the surfaces 320 is slowed so that the dust is more easily collected. However, when the density of the filler 330 is high, since it may give discomfort to the wearer's breathing, the density of the filler 330 needs to be appropriately adjusted.

In addition, the first electrode surface 310 and the second electrode surface 320 are formed in a structure that can be separated/coupled from each other, so that the filler 330 is disposed between the first electrode surface 310 and the second electrode surface 320 . By being configured to be inserted or removed, the filler 330 may also be configured to be washable and washable.

3 and 4, the first ventilation hole 311 and the second ventilation hole 321 are illustrated as being formed in a circular shape as an example, but this is an example of the first ventilation hole 311 and the second ventilation hole 321. The shape, size, arrangement interval, etc. of the can be variously adjusted. For example, the first ventilation hole 311 and the second ventilation hole 321 may be implemented in various shapes such as a square, a triangle, or a bar shape.

And, on the first electrode surface 610 and the second electrode surface 620 , a first voltage (a positive (+) voltage as an example) and a second voltage (here, an example) of the high voltage and low current signal generated by the power circuit unit 220 . negative (-) voltage) may be applied respectively.

In addition, a plurality of ventilation holes 611 and 621 are formed in each of the first electrode surface 610 and the second electrode surface 620 so as not to overlap each other according to a predetermined pattern. That is, in the same manner as in FIGS. 3 and 4 , the first electrode surface 610 and the second electrode surface are prevented from being formed in which the plurality of first ventilation holes 611 and the plurality of second ventilation holes 621 overlap each other. 620, respectively. Here, the shape and size of the first vent hole 311 and the second vent hole 321 , and an arrangement interval may be variously adjusted.

However, in the dust filter of FIGS. 6 and 7 , a plurality of first guide walls 612 surrounding the outside of each of the plurality of first ventilation holes 611 are further formed on the first electrode surface 610 , and the second electrode surface At 620 , a plurality of second guide walls 622 are further formed in positions and shapes corresponding to the plurality of first guide walls 612 . Here, when each of the plurality of second guide walls 622 is coupled to the first electrode surface 610 and the second electrode surface 620 as shown in FIG. 7 , the corresponding one of the plurality of first guide walls 612 is It may be formed in a shape surrounding the outer periphery of the first guide wall.

As shown in FIG. 8 , the plurality of first vent holes 611 may be formed in a circular shape, and each of the plurality of first guide walls 612 protrude from the edge of the first vent hole 611 . can be formed. And as can be seen in FIG. 9 (a), each of the plurality of second guide walls 622 has a larger diameter than the plurality of first guide walls 612, and as shown in (b), a plurality of first The guide wall 612 is formed to protrude in a direction opposite to the protruding direction. However, a ventilation hole is not formed inside the second guide wall 622 . A plurality of second ventilation holes 621 in the second electrode surface 620 pass through the second electrode surface 620 between the plurality of second guide walls 622 as shown in (a) of FIG. 9 . is formed by

Here, the plurality of first guide walls 612 are formed in a cylindrical shape according to the circular shape of the first vent hole 611 , and the plurality of second guide walls 622 surround the outer circumference of the first guide wall 612 . For this, it was formed in a cylindrical shape according to the shape of the first guide wall 612 . Therefore, if the first vent hole 611 is formed in a shape other than a circular shape, the first guide wall 612 and the second guide wall 622 also have various shapes corresponding to the shape of the first vent hole 611 . can be formed with

Compared with the dust filter of FIG. 5 , the first guide wall 612 and the second guide wall 622 interfere with the smooth flow of air in the air inflow path, thereby slowing the movement speed of the air. .

The dust filter shown in FIG. 5 also blocks the wearer's breathing so that it does not directly affect the air outside the mask so that dust can be easily collected in the dust filter. However, when the wearer's breathing intensity is strong, the first electrode surface 310 There may be cases in which dust cannot be stably collected only by static electricity generated on the second electrode surface 320 and the second electrode surface 320 . However, as shown in FIG. 10 , when the first guide wall 612 and the second guide wall 622 are additionally provided in the dust filter, air is released into the first guide wall 612 and the second guide wall 622 . ) is introduced into the mask through the space between In other words, it allows the dust to be collected more efficiently.

In addition, the first guide wall 612 and the second guide wall 622 are implemented separately from the first and second electrode surfaces 610 and 620 and are not coupled, and the first and second electrode surfaces 610 and 620 and It may be integrally formed of the same material. That is, the first guide wall 612 and the second guide wall 622 also generate static electricity, and due to this, the dust introduced into the dust filter is removed from the first and second electrode surfaces 610 and 620 as well as the first Since the guide wall 612 and the second guide wall 622 are also collected, it is possible to more reliably collect dust.

In the above description, the first guide wall 612 is formed on the first electrode surface 610 and the second guide wall 622 is all formed on the second electrode surface 620 , but in some cases, the first Only one of the guide wall 612 or the second guide wall 622 may be formed.
