Description

Nose Respirator {NOSE RESPIRATOR}

The present invention relates to a respirator worn on the nose, and more particularly, to a nasal respirator that effectively prevents dust in the air from being inhaled into the body through the nose during nasal breathing.

In general, masks are used to block various kinds of dust or yellow dust from entering the body when going out.

The mask for this purpose is mainly made of fabric while forming a flat shape, and when using it, the surface of the mask is in close contact with the face including the nose and mouth while the rings attached to both sides are held on both ears of the user.

However, in reality, when wearing a mask made of a flat shape, the entire surface of the mask does not adhere to the user's face, and there are many cases where a gap is created between the face and the mask, which causes the user to breathe while wearing the mask. When drinking, air is sucked through the gap between the face and the mask, and there is a problem that dust or yellow dust cannot be walked and flow into the body.

In addition, masks in the form of covering the mouth and nose are contaminated by bodily fluids contained in the exhaled breath through the mouth or nose, making it easier to feel odor and discomfort, resulting in the inconvenience of frequent replacement of the mask or frequent washing. There is this.

In addition, when a user wears glasses together with a mask, some of the exhalation comes into contact with the surface of the glasses through a gap formed between the mask and the glasses, and there is a problem such as fogging on the glasses.

Various types of masks have been proposed to solve the problems of such a planar mask.

As an example, Korean Utility Model Registration No. 20-0405907 discloses a “mask with a nose wrap”.

The “mask with a nose wrap” is composed of a pad made of a square piece of cloth, an earring string attached to both opposite sides of the pad, and a nose wrap attached to the center of the upper side of the pad. By blocking the nose that is emitted to the top, it prevents fogging on the glasses, and the dust that flows into the nose can be removed.

However, since the ``mask with a nose cover'' is also a form that closes the user's mouth when used, the problem of contaminating the mask by bodily fluids contained in exhalation cannot be solved. If it is not adhered to, there is a disadvantage that there is a high risk of nose discharge to the upper part, and it is still insufficient to solve the problems of the existing mask.

Korean Patent Application Publication No. 10-2012-0002502 Korean Patent Application Publication No. 10-2016-0079412 Korean Patent Application Publication No. 10-2016-0108859 Korean Patent Application Publication No. 10-2016-0134338 Korean Patent Application Publication No. 10-2016-0144038

Therefore, the present invention has been devised in consideration of such a point, and not only can be worn in a close contact state while surrounding the user's nose, but also can filter out fine dust in the air, and can be fixed by hanging on glasses, etc. By implementing a new type of nasal respirator that is easy to wear, such as a nose respirator, it is possible to secure functionality, such as reliably blocking fine dust in the air, and to improve usability and handling by being easily worn and used.

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

1 and 2 are perspective views showing a nasal respirator according to an embodiment of the present invention, and Figure 3 is a cross-sectional view showing a nasal respirator according to an embodiment of the present invention.

As shown in Figs. 1 to 3, the nasal respirator includes a nose wrap 11 as a means to seal the nose area during nasal breathing.

The nose wrapper 11 is formed in a shape capable of being in close contact with the skin along the contour around the nose while accommodating a person's nose.

For example, the nose wrapper 11 has a front hole for the combination of the filter device 12 to be described later, and at the same time, the back side is opened to close the skin while surrounding the nose of a person, and is similar to the shape of a person's nose. It can be made in the form of a barrel that can accommodate the nose generously.

Here, it is preferable that the nose wrap 11 is made of a material such as a soft and flexible synthetic resin material, for example, silicone rubber, while having an appropriate strength.

On both sides of the nose wrap 11, an air opening/closing film 10 made of a silicone rubber material that serves to selectively block air is formed.

The air opening/closing film 10 at this time is a substantially triangular film having a relatively thin thickness compared to the thickness of the nose wrap material, and is adhered or integrally formed to the outer surface of the nose wrap 11 using a portion of the edge of the film. It is formed in a structure that is attached to the nose wrap 11 side through, and the air opening and closing film 10 formed in this way covers the air discharge holes 25 formed on both sides of the nose wrap 11 from the outside. You will be able to.

For example, the air opening and closing membrane 10 has a relatively thickest thickness on the side attached to the nose wrap 11, and gradually decreases in thickness toward the opposite side. It can be easily flipped or restored by the flow of.

At this time, the area of the air opening and closing membrane 10 is a relatively large area compared to the area of the air exhaust hole 25, so that the air opening and closing membrane 10 uses its own restoring force to close the air exhaust hole 25. In the covered state (a state in which the edge portion of the air opening and closing membrane is in close contact with the surface), the air discharge hole 25 can be completely blocked.

Accordingly, when the user breathes through the nose while wearing the nose cover 11, the air opening and closing membrane 10 is attached by the suction pressure inside the nose cover and the air discharge hole 25 is opened. The air discharge hole 25 is blocked by being in close contact with the surrounding area, and in the end, in this state, outside air is not introduced through the air discharge hole 25, while when the user exhales through the nose, discharge at this time Due to the pressure, the air opening and closing membrane 10 is tilted outward and the air discharge hole 25 is opened. Eventually, in this state, the air inside the nose wrapper can be discharged outward through the air discharge hole 25. There will be.

In addition, a ring 18 is formed on the upper front side of the nose wrap 11, and a hole 17 of the holder 20, which will be described later, is fitted to the ring 18 at this time, and can be hooked. Band brackets 21 are formed on both sides of the wrapper 11, and one end of the band 23, which will be described later, is tied to the band bracket 21 at this time and can be connected.

In particular, the nose wrap 11 includes an airtight frame member 14 as a means for reinforcing the close contact state around the user's nose.

The airtight rim member 14 is made of a soft and flexible silicone rubber material, and is supported while being combined or formed integrally with the edge of the rear open portion of the nose wrap 11, and along the edge at this time, the inside with a certain width It forms a shape that is tilted toward.

For example, the airtight rim member 14 may be formed in a two-ply overlapping shape with a gentle curvature at the edge of the rear open portion of the nose wrap 11.

Accordingly, when the nose wrap 11 is worn, the airtight rim member 14 is slightly pressed along the contour around the nose and is in close contact with the skin to completely seal the nose area. ), it is possible to completely block the inflow of outside air through the edge.

In addition, the nasal respirator includes a filter device 12 as a means for filtering foreign substances or the like in the air introduced during breathing.

The filter device 12 is installed in the front opening of the nose wrap 11 and serves to filter foreign substances in the air sucked through the nose.

To this end, the filter device 12 includes a filter housing 15 that serves as a filter support and an air passage, and at least one filter member 16 that filters foreign substances.

The filter housing 15 is in the form of a cylindrical tube, by a coupling structure between the groove and the protrusion in the front opening of the nose wrap 11, for example, the coupling structure between the groove on the filter housing side and the protrusion on the nose cover ( It is joined to the 11) side.

Further, a plurality of slits 26 are formed on the upper side of the outer circumferential surface of the filter housing 15, and the filter member 16 is retractably inserted and removed through the slits 26 at this time.

The filter member 16 is a disk-shaped filter supported in a circular frame having the same diameter as the filter housing, and is coaxially mounted in the filter housing 15 through the slit 26 of the filter housing 15, In such a mounted state, the outer circumferential surface of the filter member 16 and the outer circumferential surface of the filter housing 15 can form the same surface.

In particular, the filter member 16 can perform a filtering function in multiple stages, for example, it is possible to perform a two-stage air cleaning step using the pre-filter 16a and the HEPA filter 16b.

Here, the pre-filter 16a mounted at the front is a high-efficiency pre-filter that removes dust having large particles, and protects the HEPA filter 16b, so that the initial high performance can be maintained even when used for a long time.

In addition, the HEPA filter 16b is a high-performance filter that removes ultra-fine dust, removes harmful gas/smog, prevents yellow dust, and SARS virus, and can remove viruses of 0.01 microns or less.

Usually, in the case of a general product, there is an inefficient aspect of having to replace the entire filter package even when a specific filter reaches the end of its life by tying several filters in one package. However, in the case of the filter device 12 provided by the present invention, each Since the filters are independent for each stage and can be individually mounted and replaced, there is an advantage that more economical and efficient operation is possible.

The filter member 16 of the filter device 12 may be applied by appropriately adjusting the thickness, for example, by varying the thickness of the pre-filter 16a and the HEPA filter 16b. It is possible to use the pre-filter 16a by applying it thicker than the filter 16b or thinner than the HEPA filter 16b.

In addition, the nasal respirator includes various types of nose wrap support devices 13 as means for maintaining the wearing state of the nose wrap 11.

As an example, as can be seen in FIGS. 1 to 3, the nose wrapper support device 13 may be made of a holder 20 capable of hanging the nose wrapper 11 on the side of the glasses.

This holder 20 is a member of an approximately "T" shape, and a hole 17 is formed at the lower end thereof so that it can be coupled to the ring 18 formed on the nose wrap 11 in a detachable structure. There is, and hooks 19 are formed on both sides at the upper end so that it can be hung over the eyeglasses, for example, the bridge part of the glasses through this.

Accordingly, after coupling the holder 20 to the nose wrap 11, when the hook 19 of the holder 20 is hooked on the bridge of the eyeglass-tae while the nose wrap 11 is worn on the nose, the nose wrapper ( 11) can be maintained in the wearing state.

As another example, as shown in FIG. 4, the nose wrapper support device 13 may be made of a pair of bands 23 that can be tied to the back of the user's head to hold the nose wrapper 11.

Each one of such a pair of bands 23 is connected to the band bracket 21 formed on both sides of the nose wrap 11, and each other is a Velcro tape 22a, which can be attached to and removed from each other. 22b) is formed.

Accordingly, in a state where the nose wrap 11 is worn on the nose, the bands 23 on both sides are rotated behind the head, and then the Velcro tapes 22a and 22b are attached to the back of the head, so that the nose wrap 11 is worn. Can be maintained stably.

Of course, even in the case of a nasal respirator to which the nose wrapper support device 13 consisting of a pair of bands 23 is applied, the nose wrapper 11, the filter device 12, and the like can be applied in the same manner as in the above embodiment.

As another example, as can be seen in FIG. 5, the nose wrapper support device 13 may be made of a pair of cylindrical nasal inserts 24 that can support the nose wrapper 11 in a state of being inserted into the nose.

The cylindrical nasal insert 24 includes a body member in the shape of a square block made of a silicon rubber material, etc., and a pair of parallel pipe members protruding from one side of the body member and penetrating in the axial direction. By inserting the tubular member of the user's nose, the cylindrical nasal insert 24 can be supported on the nose.

This cylindrical nasal insert 24 can be coupled to the inside of the nose wrap 11 through a body member that is fitted to both supports 27 formed on the inner wall of the nose wrap 11.

Accordingly, after coupling the cylindrical nasal insert 24 to the inside of the nose wrap 11, the nose wrap 11 is worn on the nose and at the same time, the tubular member of the cylindrical nasal insert 24 is attached to the user's nose. When inserted, the wearing state of the nose wrapper 11 can be maintained.

Therefore, looking at the state of use of the nasal respirator configured as described above is as follows.

Figure 6 is a front view showing the state of use of the nasal respirator according to the present invention.

As shown in Figure 6, here shows a state in which the nose wrap 11 is worn on the nose using the nose wrap support device 13 made of the holder 20.

To this end, the nose wrapper 11 covers the user's nose and at the same time, the nose wrapper support device 13 on the upper side of the nose wrapper 11, that is, the hook 19 of the holder 20, of the eyeglasses that the user is wearing. When hanging on the bridge, the nose wrap 11 can be fixed in close contact with the nose.

In this state, when the user breathes through the nose, external air passes through the filter member 16 of the filter device 12, that is, passes through the pre-filter 16a and the HEPA filter 16b in order to It enters the inside of the wrapper 11, and is continuously sucked into the body through the user's nose.

At this time, foreign substances such as fine dust contained in the inhaled air are completely removed while passing through the pre-filter 16a and the HEPA filter 16b, so that the user can inhale cleanly purified air.

In addition, the air opening/closing membrane 10 in the nose wrap 11 can be maintained in a closed state by the pressure when inhaling through the nose.

On the other hand, when the user exhales through the nose, the air opening and closing membrane 10 is lifted outward by the discharge pressure at this time and the air discharge hole 25 in the nose wrap 11 is opened. The breath that the user exhales is able to escape.

As described above, in the present invention, it is possible to wear it in a tight contact state while wrapping around the user's nose when breathing the nose, and it is possible to filter fine dust in the air, as well as to fix it by hanging on glasses, etc. By providing a nasal respirator, excellent functionality can be secured, such as being able to reliably block fine dust in the air, and anyone can easily wear and use without inconvenience.
