Description
Technical Field
The present invention relates to a nasal insert type mask, and more particularly, to a nasal insert type mask which is formed to be simply inserted into nostrils of a user, thereby being conveniently worn, not obstructing communication in case of emergency, and which is provided with a dry filter part and a wet filter part, thereby effectively removing dust having large particles into fine dust, and can be worn while varying an outer diameter according to the size of each nostril of the user, thereby preventing dropping due to pressure during breathing, and which can utilize the entire area of the wet filter since the direction of external air flowing into the wet filter is formed from below the wet filter.
Background
Masks that are generally worn in construction sites and the like are manufactured in a mask form that is worn in close contact with the mouth and nose of the face, or in a mask form that can cover the eyes, nose, and mouth of the face at the same time, so as to prevent dust from flowing into the bronchi through the nose or mouth.
However, the mask as described above has a problem that the area covering the face is large and rough, and cannot correspond to the different face shapes of each user, so that a gap is formed between the skin of the user and the edge of the mask, and the mask mostly has a shape of blocking the mouth, so that communication is not smooth when wearing the mask.
Further, since the mask is in a form of covering the nose and the mouth, it is necessary to use a filter over a large area, and thus there is a limitation that only a dry filter can be used, thereby reducing dust filtering efficiency and drying the bronchial tubes.
Therefore, there is a need to develop a nasal mask which can be worn by simply inserting into nostrils, can improve the filtering efficiency of dust, and can prevent bronchial tubes from becoming dry.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 8, the present invention includes: an outer cylinder 100 formed in a cylindrical shape and having a lattice-shaped or strip-shaped upper screen 110 formed at an upper end thereof; a dry filter unit 300 including a dry filter accommodated inside the outer tube 100; the wet filter 200 is inserted and coupled from below the outer tube 100 to the inner peripheral edge of the outer tube 100 in close contact therewith.
The outer cylinder 100 has a function of providing an installation space so that the dry filter part 300 is received inside, the wet filter part 200 is combined at a lower portion, and for this, is formed in a cylindrical shape, and the upper screen 110 is formed in a lattice shape or a bar shape at an upper end.
The upper screen 110 is formed in a lattice shape or a bar shape, extends from the upper end of the outer cylindrical part 100, and may be formed integrally with the outer cylindrical part 100 by injection molding, or may be coupled to the upper end or inside the upper end of the outer cylindrical part 100 by bonding or the like. The upper screen 110 has a function of preventing the dry filter accommodated inside the outer tube portion 100 from being detached above the outer tube portion 100.
Further, in the outer tube part 100, a support protrusion 120 is protrudingly formed at an outer peripheral edge side to support an upper end of an elastic outer warp part 500 to be described later, and an upper outer coupling part 101 of a screw shape is formed below the support protrusion 120 to be spaced apart from the support protrusion 120 and to be engaged with an upper inner coupling part 601 of an outer diameter adjusting part 600 to be described later.
The dry filter part 300 has a function of preventing dust in the air from being sucked into the inside of the nose of the user, and is formed in a cylindrical shape and disposed inside the outer tube part 100 for this purpose.
The dry filter unit 300 may be configured in a plurality of layers, and filters of the respective layers may be configured by different types of filters such as a nano filter, a deodorizing filter, and a high efficiency particulate air filter, or may be configured by one filter. A hard structure 310 contacting the upper end of the inner tube may be further formed at the lower end of the dry filter 300. The hard structure 310 has an annular edge so that it can stably support the upper end of the inner tube portion.
The wet filter unit 200 has a function of adsorbing and removing dust contained in the external air when a user breathes, and thus has an open upper end and a lower end including: an inner cylinder portion having a sealed cylindrical shape; a plurality of breathing through holes 221 formed through the side surface of the inner tube portion; and a wet filter 400 accommodated inside the inner cylindrical portion.
The inner cylindrical portion has a function of accommodating the wet filter 400 and the chemical liquid to be absorbed by the wet filter 400 therein, and is formed in a cylindrical shape having an open upper end and a sealed lower end.
An intake through hole is formed through one side surface of the inner cylinder portion so that air can be taken in from the outside. In this case, since the residual chemical solution absorbed by the wet filter 400 exists inside the inner cylindrical portion, it is preferable that a suction through hole is formed in a side surface spaced apart from the lowermost end of the inner cylindrical portion by a predetermined height, so as to prevent the chemical solution contained therein from flowing out.
In this case, it is preferable that an outer circumferential edge of the wet filter 400 is in close contact with an inner circumferential edge of the inner cylinder part, so that the air flowing in through the suction through-holes passes through the wet filter 400 and then moves to the upper dry filter part 300.
On the other hand, the mask of the present invention is inserted into the nose, and the size of each nostril of a person is different, so that the person with large nostrils may fall off due to exhalation.
Therefore, the present invention is configured to be used with varying outer diameters according to the size of each user's nostrils. To this end, the invention comprises: an elastic outer diameter part 500 inserted from the outside of the outer cylinder part 100 and elastically expanded to the outside when receiving a force of compression in the vertical direction; the outer diameter adjusting part 600 provides a compression force in the up and down direction to the elastic outer diameter part 500. Further, for this purpose, in the outer cylinder part 100, a support protrusion 120 is protrudingly formed at an outer circumferential edge to support an upper end of the elastic outer diameter part 500, and an upper outer side coupling part 101 having a screw shape is formed below the support protrusion 120 apart from the support protrusion 120 to engage the outer diameter adjusting part 600.
The elastic outer diameter part 500 is a pipe shape having a side surface sealed and opened at upper and lower portions, is inserted from the outside of the outer cylindrical part 100, and is supported at its upper end in contact with the support protrusion 120. The elastic outer diameter part 500 is made of an elastic material, has the same inner diameter at the upper and lower ends as the outer diameter of the outer cylinder part 100 to be in contact with the outer circumferential edge of the outer cylinder part 100, and has a larger outer diameter at the central portion than the upper and lower ends.
The elastic outer diameter part 500 is formed in a double tube shape, which includes: an outer tube 510 that contacts the user's nostrils; and an inner tube 520 for expanding the outer tube inside the outer tube 510 to the outside.
The outer tube 510 is formed in a shape curved to protrude outward, and is bonded to the inner tube 520 at upper and lower ends thereof by a predetermined length. The upper end of the outer tube 510 is supported by the support protrusion 120, and the lower end of the outer tube 510 is supported by the outer diameter adjusting part 600.
The inner pipe 520 is disposed inside the outer pipe 510, and is configured such that the inner pipe 520 meets the upper end, the lower end, and the middle end of the outer pipe 510. The inner pipe 520 is formed such that upper and lower ends thereof are bonded to upper and lower ends of the outer pipe 510 by a predetermined length, and a portion not contacting the outer pipe 510 has a shape that is concave inward and curved. That is, as shown in fig. 2, the inner tube 520 is shown to have a shape of a "herringbone" in a cross section in the longitudinal direction.
The upper end of the inner pipe 520 is supported by the supporting protrusion 120, the lower end of the inner pipe 520 is supported by the outer diameter adjusting part 600, and when the outer diameter adjusting part 600 is rotated in the forward direction to raise the outer diameter adjusting part 600, the distance between the upper end and the lower end of the inner pipe 520 gradually approaches, and the inner side is concaved and bent as the inner pipe 520 is characterized in that the middle end is pushed to the outside as the inner pipe 520 approaches from the middle end to the upper end and the lower end. In this case, since the middle end of the inner tube 520 is in contact with the outer tube 510, the outer tube 510 is also expanded outward and has an increased outer diameter.
On one hand, the inner tube 520 should not be deformed by pressure applied to the upper and lower ends, wherein the ends should be pushed outward, and the outer tube 510 should be elastically expanded according to the degree to which the middle end of the inner tube 520 is pushed out, and therefore, it is preferable that the outer tube 510 is made of a relatively soft material, the inner tube 520 is made of a material harder than the outer tube 510, and the upper and lower ends of each are bonded.
The outer diameter adjusting part 600 has a function of changing the outer diameter of the elastic outer diameter part 500 by providing a compression force to the elastic outer diameter part 500, and for this purpose, it is formed in a ring shape, and an upper inside combining part 601 formed with a screw shape at an inner circumferential edge thereof so as to be engaged with the upper outside combining part 101 formed at the outer cylinder part 100, and an upper end thereof is connected with a lower end of the elastic outer diameter part 500.
That is, the outer diameter adjusting part 600 is coupled to the outer tube part 100 together with the nut, and has a characteristic of rising when rotating in the forward direction and falling when rotating in the reverse direction. When the outer diameter adjustment part 600 rotates in the forward direction and ascends, the upper end of the outer diameter adjustment part 600 pushes the lower end of the elastic outer diameter part 500 upward and the elastic outer diameter part 500 expands outward, and when the outer diameter adjustment part 600 rotates in the reverse direction and descends, the compressive force applied by the upper end of the outer diameter adjustment part 600 is gradually released, whereby the elastic outer diameter part 500 is shrunk inward.
On the other hand, when the exhalation plate 214 is provided at one side of the wet type filter unit 200 and is blocked when inhaling and is opened only when exhaling, the force with which the mask of the present invention enters the nostrils when inhaling is greater than the force with which the mask falls off from the nostrils when exhaling. Therefore, the outer peripheral edge of the lower end of the outer diameter-adjusting part 600 may protrude outward and form a stopper 610. Since the stopper 610 protrudes from the outer circumferential edge of the lower end of the outer diameter adjusting part 600, the mask of the present invention is inserted into the nostril and is caught at the entrance of the nostril, thereby preventing the mask of the present invention from being inhaled into the nostril. The stopper 610 may be formed on the entire outer circumferential edge of the outer diameter-adjusting portion, or may be formed in an eccentric manner such that one outer circumferential edge does not protrude. The reason why the stopper 610 is formed eccentrically is that the stopper 610 cannot support the human body at a middle portion without a step difference.
On the other hand, if the breathing through-hole 221 is formed in the side surface of the inner tube portion and the wet filter 400 is configured to contact the inner peripheral edge of the inner tube portion, there is a concern that external air may reach the dry filter from the breathing through-hole 221 only through the vicinity of the edge of the wet filter 400 during air intake. In this case, there may occur a problem that replacement is often required without using the entire area of the wet filter 400. Therefore, the present invention is configured to allow air flowing in through the breathing hole to pass through the wet filter 400 from below the wet filter 40.
To this end, the inner cylinder portion of the present invention includes: an upper body 210 formed in a cylindrical shape and inserted and coupled to the outer tube 100; a lower body 220 having a lower end formed in a sealed cylindrical shape, coupled to the upper body 210 from below the upper body 210, and having a breathing through hole 221 formed therethrough on one side of a side surface thereof; and an inner bottom 230 which is accommodated in the inner side of the lower body 220, is formed to be spaced apart from the inner peripheral edge of the lower body 220, in which the breathing through-hole 221 is formed, and the lower inner side surface of the lower body 220, has a plurality of bottom holes 234 formed therethrough at the bottom surface thereof, and accommodates the wet filter 400 therein.
The upper body 210 provides a mounting space to enable mounting of the lower body 220 and the inner base part 230, and provides a flow path from the wet filter 400 to the outer tub 100. To this end, the upper body 210 is formed in a cylindrical shape and is insert-coupled to the outer cylindrical part 100, and the lower body 220 is coupled to a lower end portion thereof from below.
In the upper body 210, a lower mesh having a lattice shape or a bar shape is formed to extend inward of an inner peripheral edge so that the wet filter 400 does not flow upward when a user inhales. The lower mesh 211 may be spaced apart from the upper end of the wet filter 400 by a predetermined distance without excessively pressing the wet filter 400, and may be located at any position as long as the wet filter 400 does not come off the inner bottom 230 as the wet filter 400 moves upward in response to the user's breath.
A lower outer coupling portion 212 having a screw shape is formed at a lower end of an outer peripheral edge of the upper body 210, and is engaged with a lower inner coupling portion 222 of a lower body 220, which will be described later, to couple the upper body 210 and the lower body 220.
On the other hand, an exhalation port 213 is formed through one side of the outer peripheral edge of the upper main body 210, and an exhalation plate 214 is coupled so as to cover the exhalation port 213 from the outside of the outer peripheral edge of the upper main body 210. When a user exhales through the exhalation holes 213 and the exhalation plate 214, the exhalation plate 214 is pushed to the outside by the respiration of the exhalation holes 213 and is directly discharged to the outside, so that the exhalation can be performed rapidly, and in addition, excessive pressure is not required to be applied during the exhalation, so that the risk that the mask of the present invention falls off from the nostrils is reduced.
As shown in the left side of fig. 5 to 7, the exhalation plate 214 may be coupled by inserting a coupling protrusion extending from the exhalation plate 214 into the inside of the upper body 210, or as shown in the right side of fig. 5 to 7, a protrusion for fixing the exhalation plate 214 at a position adjacent to the exhalation port 213 protrudes from the outer peripheral edge of the upper body 210 to penetrate the exhalation plate 214, thereby fixing the exhalation plate 214.
The lower body 220 has a function of receiving and fixing the inner bottom part 230 and supplying external air to the lower side of the wet type filter 400 along a space separated from the inner bottom part 230, and for this, a lower end is formed in a sealed cylindrical shape and configured to be coupled to the upper body 210 from the lower side of the upper body 210.
A breathing through hole 221 is formed through one side surface of the lower body 220, and a lower inner coupling portion 222 having a screw shape is formed at an upper end of an inner peripheral edge so as to be engaged with the lower outer coupling portion 212 of the upper body 210.
In this case, a base pressurizing protrusion 223 is formed to protrude inside the lower inner circumferential edge of the inner coupling portion of the lower body 220, and since the base pressurizing protrusion 223 supports the lower end of the ring supporter 232 of the inner base 230, the upper end of the ring supporter 232 of the inner base 230 comes into contact with the lower end surface of the upper body 210 to be pressurized when the lower body 220 is coupled to the upper body 210. In addition, since the breathing through-hole 221 is formed below the base part pressurizing protrusion 223, external air can be circulated through a partitioned space between the inner peripheral edge of the lower body 220 and the outer peripheral edge of the inner base part 230.
On the other hand, a ring-shaped backflow preventing protrusion 224 is formed inside the inner peripheral edge of the lower body 220 so as to be spaced apart from the lower end inner surface and protrude inward to be positioned below the breathing hole 221, and the backflow preventing protrusion 224 prevents the residual medical fluid, which is not absorbed by the wet filter 400, from flowing out through the breathing hole 221.
And, a plurality of base part support pillars 225 are protrudingly formed at the lower end inner side surface of the lower body 220, and the base part support pillars 225 may support the lower end of the base part body 231 of the inner base part 230.
The inner bottom chassis 230 has a function of accommodating the wet filter 400 and forming a flow path for inflow of external air in a space separated from the lower body, and includes: a base part main body 231 formed in a barrel shape having an opened upper portion and having a base hole 234 formed in a bottom surface thereof; an annular support frame 232 formed to protrude from an outer peripheral edge of the base part main body 231 and supported at a lower end thereof by the base part pressurizing protrusion 223 of the lower main body 220; and an annular packing 233 provided on an upper surface of the annular support 232 and coupled to a lower end surface of the upper body 210.
The base body 231 has a function of accommodating the wet filter 400 and allowing external air to flow into the wet filter 400 from below, and is formed in a barrel shape having an open upper portion and a plurality of base holes 234 formed through a bottom surface thereof. In this case, the pressure of the external air flowing in through the breathing through-hole 221 and flowing in along the space partitioned between the inner peripheral edge of the lower body 220 and the outer peripheral edge of the base body 231 is maximized outside the lower end of the base body 231 and becomes less than a desired level toward the center, and thus the base hole 234 may be formed to have a diameter that becomes larger toward the center from the outside of the lower end of the base body 231. Accordingly, when the external air is introduced by the inhalation of the user, the pressure applied to each seating hole 234 is substantially equally formed, so that the external air can be uniformly passed through the entire area of the wet filter 400.
An annular support frame 232 is formed to protrude from an outer peripheral edge of the base part main body 231, and since a lower end thereof is supported by the base part pressurizing protrusion 223 of the lower main body 220, an upper end thereof is connected to a lower end surface of the upper main body 210 when the lower main body 220 is combined with the upper main body 210. That is, when the lower body 220 is screwed to the upper body 210 and coupled, it is lifted by the seating portion pressurizing protrusion 223 to be pressed against the lower end surface of the upper body 210. Since the annular support shelf 232 is provided, the external air flowing in through the breathing through-hole 221 is sealed by the inner circumferential edge of the lower body 220, the lower surface of the annular support shelf 232, and the outer circumferential edge of the base body 231 and is supplied toward the lower direction of the base body 231. In this case, even though the upper body 210 and the lower body 220 are coupled by screw threads, there is a risk that external air directly flows in the direction of the dry filter 300 through a gap between the screw threads. Therefore, when the annular seal ring 233 is provided on the upper surface of the annular support frame 232 and the annular support frame 232 is attached to the lower end surface of the upper body 210, the seal ring 233 is inserted between the lower end surface of the upper body 210 and the upper surface of the annular support frame 232. The packing 233 blocks the external air flowing in from between the coupling portions of the upper body 210 and the lower body 220 so that the external air can flow in only from the lower portion of the seating part body 231.
The invention composed by the structure has the effect of being simply inserted into the nostrils of the user so as to be convenient to wear and not to obstruct the communication in case of emergency.
In addition, the present invention has an effect that dust with large particles can be effectively removed to fine dust by providing the dry filter 300 and the wet filter 200.
Also, the present invention has an effect that the outer diameter can be changed according to the size of each user's nostril by providing the elastic outer diameter part 500 and the outer diameter adjusting part 600 to prevent the falling off due to the pressure at the time of breathing.
In addition, the present invention has an effect that the direction of the external air flowing into the wet filter is formed from below the wet filter, so that all areas of the wet filter can be used.
