Description

{Versatile mask for ultrafine particles}

The present invention relates to a multi-purpose mask for ultrafine dust which can cope with various situations.

In modern society, due to the development of large-scale industry, the amount of toxic gas emitted is not only large but also various kinds.

Several regulatory regulations have been enacted to prevent air pollution and development of purification devices has been made, but it is still not enough to prevent air pollution.

Recently, many people are suffering from fine dust which is more harmful to human body than yellow dust, and measures are not yet in place. Particularly fine dust is a problem because it causes serious diseases such as heart attack, asthma, bronchitis, pneumonia and lung cancer. As the concentration of fine dust increases, the number of cardiovascular and respiratory patients increases exponentially and the mortality rate increases. According to one study, there are about 20,000 premature deaths and about 800,000 lung-related diseases a year in the metropolitan area due to fine dust. It is estimated to be W12.3trn if it is converted into social cost.

In addition to fine dust, workers and nearby residents are exposed to various air pollutants at various industrial sites. Unless you are handling chemical fuels or organic solvents directly, there are often many types of harmful gases exposed to industrial sites. In many cases, workers often wear simple respirators rather than stifling masks, and often do not use masks to communicate during work.

Although various masks have been developed for various pollution sources, it is difficult to carry all the various masks according to the change of circumstances. Therefore, even when one mask is carried, it is often exposed to other air pollution sources .

Although masks capable of coping with various pollutants are desperately required, conventionally developed masks are too limited in use to satisfy various demands. For example, in everyday life, masks that can cope with not only fine dust but also viruses such as swine flu are not yet available.

In addition, most of the masks used in everyday life are too loose and have little dust or virus blocking effect. The masks that are specially manufactured do not have a structure in which a high-performance multilayer filter can be mounted on both the mouth and the nose, and there is not yet a mask capable of replacing the high-performance filter to cope with various special situations It is true.

More specifically, according to the mask of the present invention, the detachable air filtering filter 300 is disposed inside the nose-and-mouth main body 100 in the mask 1, An annular urethane sponge pad 400 and urethane sponge pad fixing protrusions each having a spandex fabric 402 adhered to the inner peripheral edge of the filter filter cover 301 are installed. And a hood fixing protrusion (101) and grooves (102) are provided on the hood (500).

The conventional technique shown in FIG. 1 has an advantage in that the spandex fabric improves the adhesion to the face and the filter is replaceable, thereby making it economical and environmentally friendly, and opening and closing only the mouth portion, thereby enabling food intake and conversation without removing the mask.

However, since the nose is not protected together with the nose and the filter mounted on the mouth is difficult to be equipped with a multi-layer composite filter, it is not sufficient to simultaneously block viruses and ultrafine dusts. There is a disadvantage that there is no means that can be brought into close contact.

Another prior art is the nose-and-mouth type mask of the patent application 10-2011-0007565 shown in Fig.

The prior art of FIG. 2 specifically includes a nose-and-mouth-type mask for filtering air, comprising a nose mask 100 and a mouth mask 200 detachable from the nose mask, And a unidirectional exhaust diaphragm formed to cover a plurality of vent holes formed to communicate with the outside of the nasal mask to discharge air inside the nasal mask and block inflow of air outside the nasal mask, Is a nose-and-tear-off mask that is formed obliquely to the user's inscription.

According to the above-described configuration, the conventional art shown in FIG. 2 has an advantage in that unnecessary inflow of outside air is blocked, the nose mask and the mouth mask are easily detached and attached, and air and moisture inside the mask are smoothly discharged.

However, the prior art of FIG. 2 does not have a structure capable of removing a strong composite filter as in the prior art shown in FIG. 1, and has to use a strap to be put on the ear so that when a helmet or the like is worn, And there is no means for replacing the filter, so there is a problem that one has to cope with a source of pollution.

Conventional ear-strapless masks are designed to use sticky materials that adhere to the skin, but such sticky materials are often harmful to the human body and are not good for skin health. Therefore, a mask that can be worn without a strap .

If a high-performance filter is used, most of the gas masks for special purposes can not be used in everyday life by using gas masks. Therefore, it is necessary to develop masks that can be applied to high-performance filters while still appearing as natural and normal masks.

Therefore, it is possible to adopt a composite filter capable of coping with various air pollution sources such as pollution, toxic gas, fine dust, virus and the like and having a depth that can effectively block pollutants. Also, While it is possible to attach it to the face while applying a high performance filter, it is required to develop a cosmetic natural mask.

The multi-purpose mask according to the present invention has the following effects.

First, it is possible to adopt a high-performance composite filter with a deep depth, so that various air pollution sources can be simultaneously shielded with excellent efficiency. In particular, it has an excellent effect of blocking ultrafine dust below PM 2.5.

Second, since the composite filter is provided as a set with different filter configurations so as to correspond to various air pollution sources, it is possible to block all the harmful gases of various workplaces from the damage of second-hand smoke only by changing the filter.

Third, while adopting a high-performance composite filter, it has a similar appearance to a usual mask, so it does not give a sense of aesthetic appearance unlike a special respiratory mask.

Fourth, since the nose and mouth can be protected by the composite filter at the same time, a smooth breathing is possible compared to a mask protecting only one of the nose and mouth.

Fifth, it is possible to wear without a strap on your ears. Even if you wear a hat or a helmet, you can wear or remove the mask without removing the hat or helmet. By using a frame made of elastic material as a removable means, I can not write.

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

3 is a front view showing a basic embodiment in which a multi-purpose mask 1 according to the present invention is worn by a user.

3, the present invention comprises a main member 10 (hereinafter, referred to as " main member 10 ") consisting of two or more face filters 11 and a prefilter 13 inserted between face filters 11 A face attachment portion 20 which is joined to the rim of the main member 10 and can be elastically fixed to the face of the main member 10, And a mouth filtration section 40 which is provided at a mouth position in the main member 10 and is composed of a second composite filter 41. [

Fig. 5 shows a sectional configuration of the main member 10. As shown in Fig. Both surfaces on the cross-sectional structure of the main member 10 are made of a surface-type filter 11, and a pre-filter 13 made of nonwoven fabric can be inserted therebetween. 5, the number of the surface filters 11 is two and the number of the prefilters 13 is one. However, there is no limitation on the number of the surface filters 11, Can be inserted. The material of the filter may be made of materials other than cotton and nonwoven fabric depending on the use environment.

And is shown with respect to the face attachment 20 in Fig. The face attachment portion 20 is made of an elastic material as shown in FIG. 4, and the multipurpose mask 1 is worn on the face by tightening the both sides of the face with the face. By adopting the fastening method, it is not necessary to use a pressure sensitive adhesive which is harmful to the human body unlike the conventional cordless mask.

However, when the face is worn on the face due to the elastic force, the curvature of the face differs for each person, so that an empty space is formed between the face attachment portion 20 and the face, so that external air can permeate into the mask. In order to prevent this, a cushion of a shape restoration material such as a memory foam may be attached to a portion of the face attachment portion 20 that is in contact with the skin. The shape of the memory foam is deformed to fill an empty space after a lapse of time from the wearing of the memory foam. Accordingly, the present invention can be applied to the face-attachment portion 20 of the present invention by using the properties of the memory foam, thereby further improving the airtightness.

In the multi-purpose mask 1 according to the present invention, since the main member 10 is basically in contact with the skin except for the nose and the mouth, external air is difficult to directly enter into the nose and mouth, The memory foam of the present invention provides a supplemental airtightness improving structure.

3, the nasal cavity 30 and the oral cavity 40 are illustrated as empty space. However, in the basic embodiment of FIG. 3, the nasal cavity 30 and the oral cavity 40 are combined The detailed configuration of the nasal filtration portion 30 is shown in Fig. 9, and the oral filtration portion 40 is shown in Figs. 7 and 8. Fig.

7 and 8 show an embodiment in which the oral filtration section 40 is detachable to the main member 10, and FIGS. 7 and 8 show the state in which the oral filtration section 40 2 attachment / detachment means 16, the second detachment means 16 and the nut portion 44 shown in FIGS. 7 and 8 and the circular attachment / detachment means 16 shown in FIGS. It is necessary to refer to it except for the groove.

Also, in the basic embodiment, the two filtration units 30 and 40 are provided irrespective of whether or not the oral filtration unit 40 and the nasal filtration unit 30 are detachable to the main member 10. Therefore, in the basic embodiment, the oral filtration section 40 and the nasal filtration section 30 may be fixedly attached to the main member.

9, the nasal filtration part 30 has a shape corresponding to the inside of the nostril, and includes two housings 32 that seal both nostrils, And a first composite filter (31) formed by sequentially embedding filters of different materials in the air flow direction in the housing (32).

More specifically, the shape of the housing 32 can be worn comfortably without a foreign object even if the housing 32 is inserted into the nasal cavity by bending the upper end portion corresponding to the internal shape of the nasal cavity. On the other hand, the housing 32 can be made to seal only the nostril opening without the need to be deeply inserted into the nostril. A semi-spherical primary purifying chamber is formed in the lower part of the first composite filter 31, and a plurality of suction ports as shown in the figure are provided therein. When the air is sucked, the suction port And adsorbs the contaminants contained in the outer circumferential surface.

At the upper end of the purifying chamber, a suction hole is formed so that air can be introduced into the first compound filter 31, and the air passing through the suction hole passes through the first compound filter 31. The first composite filter 31 is basically formed with an activated carbon layer through which the air first passes and the filter layers capable of blocking the pollution source depending on the type of air pollution are sequentially disposed on the activated carbon layer.

The oral filtration unit 40 will be described with reference to FIGS. 7 and 8. FIG. 7 and 8, the basic configuration is the same, so that Fig. 7 will be referred to.

Like the nasal filtration part 30, the oral filtration part 40 basically comprises different filter layers laminated in the depth direction of the housing 42 in the housing 42 and the housing 42. At this time, the difference from the nasal filtration part 30 is that the housing 42 is less restricted in the shape, and therefore, both sides of the cylinder, which is opened in a cylindrical shape, is closed by the membrane in which the plurality of vent holes 43 are formed. This is to increase the filtration efficiency of the second composite filter 41 by lowering the suction pressure of the air.

Hereinafter, a first embodiment of the multi-purpose mask 1 according to the present invention will be described.

In the first embodiment, both the nasal filtration portion 30 and the oral filtration portion 40 are detachable from the main member 10.

6 to 10 show the means by which the nasal filtration portion 30 and the oral filtration portion 40 can be coupled to the first and second removal means 15 and 16, respectively.

First, the detachment method of the nasal filtration portion 30 will be described with reference to FIG. 9 and 6, the detachment / attachment manner of the nasal filtration portion 30 is not shown in detail. However, there is no limitation to the detachment method of the nasal filtration section 30. For example, the first desorption section 15 may be configured such that the pre-filter 13 is partially removed from the main member 10 at the nose section and the nasal filtration section 30 The horizontal portion of the lower end of the housing 32 of the pre-filter 13 can be inserted into the portion where the pre-filter 13 is located.

Next, referring to FIG. 7, a description will be made of a manner in which the oral filtration part 40 is attached to and detached from the second detachment means 16.

The second attachment / detachment means 16 is provided at a position where the mouth is located in the main member 10, and has a shape in which a thread is formed on the outer circumferential surface and a cylindrical body on both sides is protruded in the mouth direction. Therefore, the user can bite the oral filtration part 40 of the cylindrical pipe shape coupled to the second detachment means 16 to suck air.

The cylindrical second detachment means 16 has threads formed on the outer circumferential surface of the second detachment means 16 to serve as a kind of bolt. At this time, the hollow filtration part 40 has a hollow cylinder extending on one side and a thread is formed on the inner circumferential surface of the extended part, and the nut part 44 is formed by the bolt- 16).

However, the second detachment means 16 may have a nut shape instead of a bolt, so that the second detachment means 16 may assume the role of a nut and the end of the oral filtration portion 40 may have a bolt shape. That is, one does not have to assume a fixed role.

The portion shown at the lower end in FIG. 6 becomes the second detachment means 16. 6, the second detachment means 16 has a nut shape. Therefore, when the second detachment means 16 is a nut as shown in FIG. 6, the end of the mouth filtration part 40 is a bolt part, not a nut part.

In Fig. 6, the first detachment means 15 and the second detachment means 16 are shown together.

Referring back to FIG. 7, a portion protruding in the form of a bolt at the other end is shown in addition to the nut portion 44 formed at one end. This is an alternative embodiment, in which two or more oral filtration sections 40 are provided so as to be connected side by side for special purposes. In particular, it is necessary to maximize the filtering power of the filter in the case where contagious viruses such as contagious viruses are not used for everyday purposes.

7 is a cross-sectional view taken along the line A-A in the left side view of the air vents 43 described above.

Meanwhile, it is preferable that a plurality of mouth filtration units 40 are provided for various situations. This may be to prepare for a situation where the pollution source varies according to the season, or it may be designed so as to prepare for each kind of major viruses. Or to avoid heavy metal gas in the operation of soldering or the like, or to avoid secondhand smoke in the case where the smoke is thick, depending on the place of use, or the like. It is also possible to have several sets as one set. At this time, each of the mouth filtration units 40 constituting one set may be different from each other according to purposes.

8 shows a modified embodiment of the manner in which the oral filtration portion 40 is coupled to the second means for removing 16 in the first embodiment.

In the embodiment shown in FIG. 8, the second removing unit 16 and the mouthpiece filtering unit 40 are not coupled in a threaded manner as shown in FIG. 7, but the second removing unit 16 is a stretchable ring, A circular groove perpendicular to the longitudinal direction is formed outside the housing 42 of the oral filtration section 40 so that the second detachment means 16 as a ring is coupled to the circular groove.

In this embodiment, as in the embodiment of Fig. 7 described earlier, the oral filtration part 40 can not be connected in plural in the longitudinal direction. However, the feature of this embodiment is that a plurality of circular grooves are formed at regular intervals along the longitudinal direction of the housing 42 of the oral filtration portion so that the length of the housing 42 protruding into the mouth can be adjusted. This may be for the purpose of improving the simple discomfort, and if the mouth filtration part 40 is protruded deep into the mouth depending on the user, it may cause malfunction. This phenomenon tends to occur particularly in the case of wearing for a long time, so that this aspect can be improved by the present embodiment.

Although not shown, the embodiment of FIG. 8 can also be applied to the combination of the first detachment means 15 and the nasal filtration portion 30.

10 is a sectional view of the main member 10 with reference to the center of the second detachment means 16 when the first embodiment is applied.

Fig. 11 shows a second embodiment of the multipurpose mask 1 according to the present invention. 11 shows that the auxiliary filters 38 and 48 are detachably attached to the main member 10 in addition to the nasal filtration part 30 and the oral filtration part 40 in addition to the nose part and the mouth part.

Since the breathing is performed at the nose portion and the mouth portion, particularly, the airtightness is required, so that the auxiliary filters 38 and 48 are applied so as to block the polluted air from the outside as much as possible. And the nasal auxiliary filter 38 is detachable by the first auxiliary detachment means 39. The oral auxiliary filter 48 is formed at the mouth and the oral auxiliary filter 48 is removable by the second auxiliary detachment means 49.

FIG. 12 shows a user wearing a mask according to a first embodiment of the multipurpose mask according to the present invention.

Although not shown, an antimicrobial fiber layer is provided on the surface of the memory foam which is in direct contact with the skin in the face attachment means 20, so that excessive sweating on the skin is prevented .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
