(19) Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

(20) FIGS. 1 to 6 illustrate a nasal cavity insertion type mask according to an exemplary embodiment of the present invention, FIGS. 1 and 2 illustrate an entire assembly configuration of a nasal cavity insertion type mask, FIGS. 3 and 4 illustrate a separated configuration of a nasal cavity insertion type mask, FIG. 5 illustrates a body shape in a nasal cavity insertion type mask, and FIG. 6 illustrates a shape of a fixing tube in a nasal cavity insertion type mask.

(21) As shown in FIGS. 1 to 6, a nasal cavity insertion type mask according to an exemplary embodiment of the present invention is inserted into a nose to filter external air inhaled upon breathing and includes a body 100, a filter 200, and a fixing tube 300.

(22) The body 100 maintains a form of the filter 200 inserted into a nasal cavity, is used for binding the fixing tube 300, is formed in a form in which the entire of the upper end, the lower end, and a side surface is opened to have a configuration characteristic that enhances air communication efficiency, and includes a support lower portion 110, a support upper portion 120, and a connection bar 130.

(23) The support lower portion 110 is positioned at a lower portion of the body 100, the inside thereof is formed in a cylindrical shape in which an air communicating hole 112 for smooth communication of air is vertically penetrated, and in order to binding support the fixing tube 300, a coupling groove 111 is formed at a circumference of the outside thereof.

(24) The support upper portion 120 is positioned at an upper portion of the body 100, is formed in a ring shape having the penetrated center for smooth communication of air, is formed at a position separated by a predetermined distance in an upward direction from the support lower portion 110, and this enables smooth communication of air in a side direction.

(25) The connection bar 130 connects the support lower portion 110 and the support upper portion 120 to support each configuration, at least one connection bar 130 may be used, and it is preferable that at each end portion connected to the support lower portion 110 and the support upper portion 120, a reinforcement portion for durability enhancement is further formed.

(26) Further, the support upper portion 120 is formed to have a diameter smaller than that of the support lower portion 110 and an entire shape of the body 100 has a cone shape having a gradually reducing diameter toward an upper portion and this may enable to be deeply inserted into a nasal cavity, and when the nasal cavity mask is inserted in consideration of an internal structure of the nasal cavity, the cone shape is a shape for enhancing a wearing feeling and is configured to easily perform a process of separating the nasal cavity mask inserted into the nasal cavity.

(27) The body 100 formed in the above shape is made of a synthetic resin and is preferably made of a silicon material in consideration of a wearing feeling within the nasal cavity.

(28) Further, the body 100 includes a functional composition that enhances an antibacteria effect and having far infrared ray and negative ion discharge effects and a blood circulation promotion effect, and such a functional composition may include at least one of silver (Ag), gold (Au), germanium (Ge), charcoal, elvan, sericite, activated carbon, jade, and magnet. It has been known that charcoal, elvan, sericite, activated carbon, and jade have deodorization and humidity adjustment effects in addition to blood circulation, cell activity promotion, and antibacterial functions according to discharge of far infrared rays.

(29) The magnet may absorb a portion of micro metal dust floating in the air at various kinds of industrial sites through magnetism in addition to a blood circulation promotion function.

(30) Compositions constituting the body 100 include silicon 93-96 wt %, hardener 1-3 wt %, and a functional composition 2-5 wt % in an entire composition 100 wt %, and it is preferable that a grain of the functional composition is applied in a minutely crushed form in a size of a range of 200-1000 meshes.

(31) In this case, when silicon is contained with less than 93 wt % or when a functional composition is contained to exceed 5 wt %, an elastic force of the shaped body 100 is deteriorated and thus a wearing feeling is not good, and a bonding force to the functional composition is deteriorated and thus there is a problem that a crack occurs in a product or that a product shaping performance is not good.

(32) However, when silicon is contained to exceed 96 wt %, a content of a functional composition is relatively less, and when silicon is contained to exceed 96 wt % or when a functional composition is contained with less than 2 wt %, antibacterial and far infrared ray discharge effects according to a functional composition are deteriorated and it is not good.

(33) Further, a grain size of a functional composition is less than 200 meshes, a particle is thick and thus a wearing feeling is not comfortable and there is a problem that a crack may occur in a product or that a shaping performance is not good, and if a grain size of a functional composition exceeds 1000 meshes, it is difficult to perform a crush process and thus there is a problem that product productivity is deteriorated.

(34) The filter 200 is detachably provided at an outer surface of the body 100 to perform a function of filtering a harmful material included in external air. Particularly, when a filter function of a filter is lost, the filter 200 is configured such that a user easily replaces the filter 200 and thus the body 100 and the fixing tube 300 may be reused, and the filter 200 may be easily replaced at a time point in which the user wants and thus an air purification function may be continuously maintained.

(35) Because the filter 200 is provided at the outside of the body 100, it is preferable that the filter 200 is formed in a form similar to that of the body 100.

(36) The filter 200 is formed with a combination of cottonseed, which is a natural fiber and a traditional Korean paper thread formed with a thread of a fiber form formed with Korean paper produced using the paper mulberry as a main component, and the traditional Korean paper thread has excellent antibiosis, has a good air penetration ratio, has a high far infrared ray emission rate and a deodorization effect according to a porous structure, and has a fast dry performance.

(37) More specifically, the filter 200 according to an exemplary embodiment of the present invention is a configuration with a first fiber (traditional Korean paper thread) produced using traditional Korean paper as a main component by mixing traditional Korean paper produced using the paper mulberry as a main raw material and natural cotton wool with 7:3 wt % and a second fiber formed through a process of soaking natural cottonseed produced with natural cotton wool in antibacterial water and drying the natural cottonseed, and the filter 200 is formed by weaving processing the first fiber and the second fiber. In this case, it is preferable that the weaving processed first fiber and second fiber are formed with 5:5 wt %.

(38) The antibacterial water may include any one of purple bamboo salt water in which purple bamboo salt is diluted in water, a phytoncide undiluted solution, and purple bamboo salt diluted in a phytoncide undiluted solution.

(39) The purple bamboo salt is bamboo salt formed to represent a purple color through a process of baking nine times sun-dried salt and bamboo at a high temperature, and it is known that the purple bamboo salt performs an excellent antibacterial operation and is good in other anti-inflammation operation and blood circulation promotion. It is preferable that a saturation solution of the purple bamboo salt water used in the present invention is formed and used by diluting the purple bamboo salt in water.

(40) Phytoncide is a material in which plants spout or discharge in order to resist a medical facility virus, a harmful insect, and mold, and when a person inhales phytoncide through woodland walks, it is known that the phytoncide enables his stress to be released and performs a sterilization operation. Phytoncide used in the present invention may be an extract that extracts only a phytoncide component from plants or a phytoncide extract available at a market.

(41) Further, when the purple bamboo salt and the phytoncide undiluted solution are mixed and used, a mixture is used in which purple bamboo salt is melted in phytoncide undiluted solution with the purple bamboo salt 40-60wt % and the phytoncide undiluted solution 40-60 wt % in an entire mixture 100 wt %.

(42) In an entire mixture 100 wt %, when purple bamboo salt is mixed with less than 40 wt % or when phytoncide undiluted solution is mixed to exceed 60 wt %, an effect of the purple bamboo salt slightly operates and thus it is unpreferable, and in an entire mixture 100 wt %, when purple bamboo salt is mixed to exceed 60 wt % or when phytoncide undiluted solution is mixed with less than 40wt %, a dilution amount in which the purple bamboo salt is mixed in the phytoncide undiluted solution exceeds a saturation state and thus it is unpreferable.

(43) A first fiber of the filter 200 is configured with a combination of traditional Korean paper and natural cotton wool, but when traditional Korean paper is contained less than the processing condition, various effects of a traditional Korean paper thread having traditional Korean paper as a main component become slight and the entire filter 200 is maintained in a flexible form and thus there is problem that it is difficult to maintain a shape of the filter 200. However, when traditional Korean paper is contained more than the processing condition, the filter 200 becomes hard and thus there is problem that a wearing feeling is deteriorated and that a surface of the filter 200 is rough.

(44) The filter 200 produced with the foregoing method may perform an antibacterial operation and be formed with a combination of a traditional Korean paper thread and cottonseed to adjust a physiology operation (e.g., temperature, humidity, filter) within a nose, and particularly, the filter 200 may have a heat effect of inhaled air in a winter season and adjust moisture to enhance nose health.

(45) The fixing tube 300 is coupled to an outer surface of the body 100 to enable the filter 200 to come in close contact with the body 100 and to fix the filter 200 to the body 100 such that the filter 200 is not separated from the body 100, and the fixing tube 300 comes in close contact with a skin within the nasal cavity to prevent a nasal cavity insertion type mask according to an exemplary embodiment of the present invention from being separated to the outside and enables to separate the filter 200 from a skin within the nasal cavity to prevent the filter 200 from being wet by a snot and to separately receive the snot.

(46) An entire shape of the fixing tube 300 is formed in a ring type, and the fixing tube 300 includes a coupling through-hole 310, an inner wall 320, an outer wall 330, and a snot receiving portion 340.

(47) Because a central portion of the coupling through-hole 310 is vertically penetrated, the coupling through-hole 310 may be inserted and coupled to the body 100.

(48) The inner wall 320 is a configuration for coming in close contact the filter 200 inserted into the outside of the body 100 with the body 100 and fixing the filter 200 to the body 100, and at an inner side surface of the inner wall 320 facing the coupling through-hole 310, a coupling protruding portion 321 formed in a curved shape is protruded in a direction of the coupling through-hole 310 to correspond to a shape of a coupling groove 111 of the body 100.

(49) The outer wall 330 comes in close contact with a skin within the nasal cavity and is fixed to a skin within the nasal cavity to prevent the nasal cavity insertion type mask from being separated from the nasal cavity, is formed higher than the inner wall 320 to prevent moisture such as a snot within the nasal cavity from contacting the filter 200, thereby maintaining a filter performance of the filter 200.

(50) In order to prevent the filter 200 from being wet with a snot flowing along a wall within the nasal cavity to prevent a filter performance from being deteriorated, the snot receiving portion 340 forms a separate space portion that can receive a flowing snot and forms a separated space between the inner wall 320 and the outer wall 330, and a lower portion thereof forms a space portion of a blocked U-shaped cross-section. Further, the snot receiving portion 340 is a configuration formed when the inner wall 320 and the outer wall 330 form a separated space and provides a space in which the outer wall 330 may be extended and reduced to the inside, and such a configuration enables the outer wall 330 to be extended and reduced to correspond to different nasal cavity sizes according to a user.

(51) It is preferable that the fixing tube 300 having the above shape is made of a silicon material in consideration of a wearing feeling.

(52) Further, the fixing tube 300 includes a functional composition that enhances an antibacteria effect and having far infrared ray and negative ion discharge effects and a blood circulation promotion effect, and such a functional composition may include at least one of silver (Ag), gold (Au), germanium (Ge), charcoal, elvan, sericite, activated carbon, and jade. It has been known that charcoal, elvan, sericite, activated carbon, and jade have deodorization and humidity adjustment effects in addition to blood circulation and cell activity promotion and antibacterial functions according to far infrared ray discharge.

(53) Compositions constituting the fixing tube 300 include silicon 93-96 wt %, hardener 1-3 wt %, and a functional composition 2-5 wt % in an entire composition 100 wt %, and it is preferable that a grain of the functional composition is minutely crushed in a size of a range of 200-1000 meshes.

(54) In this case, when silicon is contained with less than 93 wt % or when a functional composition is contained to exceed 5 wt %, an elastic force of the shaped fixing tube 300 is deteriorated and thus a wearing feeling is not good, and a bonding force to the functional composition is deteriorated and thus there is a problem that a crack occurs in a product or that a product shaping performance is not good.

(55) However, when silicon is contained to exceed 96 wt %, a content of a functional composition is relatively less, and when silicon is contained to exceed 96 wt % or when a functional composition is contained with less than 2 wt %, antibacterial and far infrared ray discharge effects according to a functional composition are deteriorated and it is not good.

(56) Further, when a grain size of a functional composition is less than 200 meshes, a particle is thick and thus a wearing feeling is not comfortable and there is a problem that a crack may occur in a product or that a shaping performance is not good, and when a grain size of a functional composition exceeds 1000 meshes, it is difficult to perform a crush process and thus there is a problem that product productivity is deteriorated.

Exemplary Embodiment: Production of Mixed Filter of Traditional Korean Paper Thread and Cottonseed

(57) First step: a first fiber (traditional Korean paper thread) was formed using traditional Korean paper as a main component by mixing the traditional Korean paper produced using the paper mulberry as a main component and natural cotton wool with 7:3 wt %.

(58) Second step: antibacterial water produced by mixing purple bamboo salt 50 wt % and phytoncide undiluted solution 50 wt % was prepared.

(59) Third step: natural cottonseed produced using natural cotton wool was prepared, was soaked in antibacterial water prepared at the second step, and was dried, thereby forming a second fiber.

(60) Fourth step: by weaving the first fiber and the second fiber produced at the foregoing steps, a filter having a fiber thickness of 0.4-0.8 mm and a through-hole size of 300-600 mesh was produced.

COMPARATIVE EXAMPLE 1

Synthetic Resin Filter

(61) The synthetic resin filter is a filter for a mask already available at a market and is produced using a synthetic resin (PE, PP) as a main raw material, and a filter having a through-hole size of 300-600 meshes was prepared.

COMPARATIVE EXAMPLE 2

Non-Woven Fabric Filter

(62) The non-woven fabric filter is a filter for a mask already available at a market, was produced using an antibacterial processed non-woven fabric as a main raw material, and a filter having a through-hole size of 300-600 meshes was prepared.

EXPERIMENTAL EXAMPLE 1

(63) When an air permeability experiment was performed using a mixed filter of cottonseed and a traditional Korean paper thread produced through an exemplary embodiment of the present invention, a synthetic resin filter of Comparative Example 1, and a non-woven fabric filter of Comparative Example 2, the following result was obtained. In this case, in the exemplary embodiment, Comparative Example 1, and Comparative Example 2, through-hole sizes of the filter are the same and thus a filter performance of fine dust was excluded from an experiment target.

(67) As described above, when a comparison experiment was performed with a mixed filter of cottonseed and a traditional Korean paper thread produced through an exemplary embodiment of the present invention, a filter available at a market of Comparative Example 1, and a filter available at a market of Comparative Example 2, while a fine dust filter performance is equally maintained, due to a material characteristic of the traditional Korean paper thread and the cottonseed, an air penetration ratio is remarkably high and thus it may be determined that a wearing feeling is good.

(68) Further, in an antibacterial test of a filter performed with a filter produced through an exemplary embodiment of the present invention, a filter of Comparative Example 1, and a filter of Comparative Example 2, the filter produced through an exemplary embodiment of the present invention has a bacteria reduction rate of 99.9%, but other comparison filters have little bacteria reduction rate.

(69) As can be determined through the experimental example 1 and the experimental example 2, it can be determined that a filter applied to a nasal cavity insertion type mask produced through the present invention provides a comfortable wearing feeling due to an excellent air penetration ratio and has very high antibiosis.

(70) An exemplary embodiment of the present invention has been described in detail with reference to the drawings, but it will be apparent to those skilled in the art that various modifications and variations may be made in the present invention without departing from the spirit or scope of the invention. Therefore, the scope of the present invention should be analyzed by claims to include such many modifications and variations.
