Hereinafter, with reference to FIGS. 3 to 7 , the structure of the helmet part 100 will be described in detail to describe a structure in which air is injected and discharged.

First, Figure 3 (a) shows a state in which air is injected to use the portable helmet of the present invention, and Figure 3 (b) shows a state in which air is discharged to carry or store the portable helmet of the present invention. it will be shown

The helmet part 100 is provided with a ring part 110 , a distal part 120 , a packing part 130 , and a film part 140 .

The ring part 110 has a ring shape having a hollow part, and may be partially recessed.

In detail, referring to FIG. 5 , FIG. 5 is a side view of the helmet part 100 , and the ring part 110 is provided in a ring shape with a lower part cut so that it can be put on a person's head.

In addition, with reference to FIG. 4 , the distal end 120 is symmetrically coupled around the ring portion 110 .

That is, if the ring part 110 is a body that is put on a person's head and has a fixed shape, the distal part 120 may have a spherical shape extending around the ring part 110 so as to surround the person's head.

In addition, the distal end 120 may be double inlet or outlet air inside.

That is, if air is injected into the distal end 120 through the inflator unit 200, as shown in FIG. 3 (a), it is inflated around the ring unit 110 to increase in volume and can be put on a person's head, and the ring unit If the air is discharged by (110), as shown in FIG. 3 (b), the distal end 120 is folded around the ring portion 110, the volume may be reduced.

At this time, the ring part 110 may be provided with a receiving groove 111 to accommodate the packing unit 130 , and a plurality of holes 1111 may be provided in the receiving groove 111 to rapidly discharge air to the outside. there is a characteristic

A receiving groove 111 having a predetermined thickness recessed along the upper surface of the ring part 110 is provided. Here, the upper surface of the ring part 110 means the outer surface of the helmet when the helmet part 100 is put on a person's head, and the lower surface of the ring part 110 means the inner surface in contact with the person's head. means side.

A plurality of circular holes 1111 are provided on both sides of the receiving groove 111 . Here, both sides of the receiving groove 111 are the same as both sides to which the distal end 120 is coupled when the distal end 120 is symmetrically coupled with respect to the ring unit 110 .

That is, due to the plurality of holes 1111 extending along the receiving groove 111 , the air stored in the distal end 120 may be discharged to the outside.

This has a disadvantage in that, in the case of a conventional helmet in which air is injected, an air outlet is located at a point of the helmet with a predetermined size, so that it takes a lot of time to discharge the air.

That is, while portability is easy, it takes a rather long time to be used immediately in an emergency, so there is a problem in that the number of times of use is reduced unless an air injection or exhaust operation is prepared in advance.

Accordingly, the ring part 110 of the present invention is provided with a plurality of holes 1111 provided to be perpendicular to the distal end 120 along the receiving groove 111 to discharge air from the distal end 120 instantaneously. can have an effect.

That is, since it is used as a helmet through an air inflow or exhaust operation, it is possible to quickly cope with damage to human life by minimizing the inflow or exhaust time of air.

In addition, when air is discharged from the distal end 120, the distal end 120 is compressed around the ring unit 110, so the storage space occupied is very small, so a large quantity can be stored in a limited space, and when folded, the volume is reduced It can be very compressed, so it has the effect of being easy to carry.

Conversely, in order to inject air into the distal end 120 , the packing unit 130 may be coupled to the receiving groove 111 .

In addition, the material of the packing part 130 may be polyvinyl chloride (PVC), silicone rubber, PTFE (Polytetrafluoroethylene), Teflon, Gore-Tex, etc., in addition to polyethylene, polypropylene, nylon, rubber coated fiber , polyurethane coated fiber, neoprene, etc. can be used in various materials.

This is to allow a user to sufficiently use the packing portion 130 having an appropriate elasticity even when a small force is used when coupling the packing portion 130 to the receiving groove 111 .

In addition, referring to FIG. 6 , the packing part 130 is preferably provided with a protruding fitting part 131 protruding in a circular shape along both sides thereof. Here, both sides of the packing part 130 are the same as both sides to which the distal part 120 is coupled when the distal part 120 is symmetrically coupled with respect to the ring part 110, and the hole 1111 ) may be a corresponding position.

Accordingly, the protruding fitting portion 131 is provided in plurality, and while the packing portion 130 is fitted into the receiving groove 111 , the protruding fitting portion 131 is also inserted into each hole 1111 .

This is, when injecting air into the distal end 120, so that air is not discharged through the receiving groove 111, it is possible to prevent the discharge of air by combining the packing unit 130, the protruding fitting portion 131 There is an effect that can completely block the phenomenon of air leakage by further providing.

In addition, in order to discharge air into the distal part 120 , the packing part 130 can be detachably attached from the receiving groove 111 of the ring part 110 , and it is easy to clean and thus cleanliness can be improved.

At this time, according to the present invention, there is a characteristic that the coating layer is provided along the helmet portion (100).

In detail, a coating layer is provided on the distal end 120, and the distal end 120 may be a general pad used for a helmet, nylon, natural material, synthetic resin, etc. Includes all helmet pads.

The antibacterial and deodorizing coating composition is fine powder shungite, fine powder illite, fine powder zeolite, fine powder elvanite, fine powder bentonite, fine powder diatomite, fine powder germanium, fine powder ocher, fine powder alum, fine powder jade (jade) and an inorganic powder selected from the group consisting of mixtures thereof.

As used herein, the fine powder refers to being crushed by a ball mill, jet mill, or other pulverizing device or manufactured to have the properties of a fine powder during the synthesis process, and the fine powder is defined as having an average particle diameter of 100 μm or less.

The "gait" as used in the present invention is produced as a layer (up to 2 m thick) or lenticular in a low metamorphic shale rich in small graphite microcrystals of the Proterozoic Jatulian in Shunga near the northern part of Lake Karelia Ladoga, Russia. . It is pitch-like black, dense, opaque, metallic luster. soft Hardness 2.5. d 1.75~1.80, it does not melt in the fire, and makes Seokmuk acid from concentrated nitric acid.

The chemical composition of illite as used in the present invention is (K,H3O)Al2(Si,Al)4O10(H2O,OH)2. In terms of chemical composition, some are close to muscovite, but relatively SiO2, MgO, H2O are abundant, and K2O is small. It is a mineral of the same series as hundreds of mica. It has a hardness of 1 to 2 and a specific gravity of 2.6 to 2.9. The cleavage is complete, the streak color is white, and it has an earthy luster. Considering the chemical composition or crystal structure, there is an opinion that it is not an independent mineral, but a mixed mineral containing other components. It is produced in aluminum-rich heterogeneous or tuff sedimentary rocks, and it is produced as a metamorphic mineral of hydrothermal mineralogy.

The zeolite referred to in the present invention is also called zeolite. Although there are many types, they have common features such as high water content, crystal properties, and acid phase. The hardness does not exceed 6, and the specific gravity is about 2.2. It is usually colorless transparent or white translucent. It got its name because it boils and expands when heated with a blow pipe. Most kinds dissolve in hydrochloric acid and often form a glue, but a few kinds are insoluble in hydrochloric acid. The main types include bantamite, fisheye, chabazite, soda zeolite, hewlandite, stilbite, lomontite, and inesite. It is produced in hollows or fissures of basic igneous rocks such as basalt and pyroclastic tuff, and sometimes exists as a secondary mineral in granite and gneiss. It may also be produced in gold veins and other veins. Since the bonds between each atom are loose in the crystal structure, even if the moisture filling the gap is released with high heat, the skeleton remains intact, so other particulate matter can be adsorbed. Using this property, it is used as an adsorbent and as a molecular sieve that separates particles of different sizes.

Elvan stone referred to in the present invention is known as a term used in Chinese herbal medicine, and geologically it belongs to the granite class. As quartz porphyry, feldspar porphyry, and granite porphyry, the rock name corresponds to quartz-monzonite. Quartz and feldspar are densely mixed. Yellowish white, light yellowish brown, light gray, dark green, or light green rocks with red dots or white dots evenly mixed in it resembles a rice ball made of barley rice, hence the name elvan stone. The main components are silicic anhydride and aluminum oxide, and a small amount of iron oxide is contained. What is known as yakseok is a yellowish-white elvan stone, which was used as a filter agent to purify pills and as an anti-inflammatory agent to treat skin diseases such as bruises or boils on the back. According to Donguibogam, its nature is sweet, warm, and non-toxic. It has 3 to 150,000 pores per 1 cm3, so it has strong adsorption and contains about 25,000 kinds of inorganic salts. Because it acts to exchange ions with heavy metals, it is also used as a toxic metal remover, and it is known that when heat is applied to this rock, it emits far-infrared rays. Because of these characteristics, it is used in various industries such as jjimjilbang, tableware, and medical equipment.

The benzoite referred to in the present invention often contains quartz, feldspar, zeolite, and the like. Colors include white, gray, light brown, and light green. It has pearl luster and wax-like luster and is produced as a dense mass with a sense of fat. Tuff and glassy rhyolite are altered. Its use is very wide, and it is also used as the main component of diwater for petroleum refining, as a binder for castings, as an admixture for ceramic materials, and as a base agent for ointments. The name is derived from the strata of the state of Wyoming, USA, where it was discovered.

Diatomaceous earth referred to in the present invention is mainly made of silicic acid (SiO2), and has a white or grayish white color. It is light and soft enough to be smeared with powder when touched with your fingers. Because of its fine porosity, it has strong absorption and is a poor conductor of heat. Diatomaceous earth in Korea is produced as soil in the tertiary or quaternary strata. During the Old 3rd Period of our country, fault movements in the northeast to northeast directions occurred, forming rift sedimentary basins in various places. The Yeongil Basin, the Jigji Belt between Gilju and Myeongcheon, the Jigji Belt between Seoul and Wonsan, and the Tuman River Basin were formed, and the tertiary layer was deposited here. When the sedimentary layer was formed, diatoms were deposited in small shallow lakes or freshwater basins in various places to form mineral deposits. Among these sedimentary basins, diatomaceous earth in Yeongil Bay is the largest in terms of diatomite deposits, and is concentrated in Wolseong and Yeongil, Gyeongsangbuk-do. In addition, in North Hamgyong Province, Haenghyeon-ri and Anbyeon-myeon Anbyeon-myeon and Namsan-ri, Anbyeon-gun, Anbyeon-gun, Bupyeong-dong and Jubuk-myeon, Gyeongseong-gun, Gyeongseong-gun, Hoemun Mine, Sanbon Mine, Ungpyeong-myeon, Gilju-gun, Myeongcheon-gun Myeongcheon Mine, Myeongcheon-gun Seomyeon Baengnok Mine, Gangwon-do There are known production areas such as Sephori, Gosap-myeon, Pyeonggang-gun. The development of diatomaceous earth as a mineral deposit in Korea began in 1941 when it was incorporated as a designated legal mineral by the 'Joseon Mining Ordinance'. Since then, domestic diatomite deposits have been discovered in various places, and it is said that diatomaceous earth produced in Iil-ri, Yangbuk-myeon, Wolseong-gun, Gyeongsangbuk-do was critically used in the manufacture of Japanese Asahi furnaces in Nodong-ri, Gyeongju-si. In recent years, it is used as a fireproof material, and because of its strong absorbency, it is mostly used as a filter material for the purification of industrial water, water supply, medicine, food, etc. It is also used as a filler for plastics and paper, an adsorbent for dynamite, a hemostatic agent, and a mixture of cement.

Germanium as used in the present invention has an element symbol Ge, an atomic number 32, and an atomic weight of 72.59±3. Its existence was predicted by D. I. Mendeleev in 1871 and it was called Eka silicon, but it was discovered in 1986 by German chemist C. A. Winkler in Ag GeS and named after Germany's Latin name "Germania". Because it is similar to silicon, it exists widely by substituting for silicon in silicate in the earth's crust, and is contained in sulfide minerals or coal containing copper or zinc, but very few minerals mainly containing germanium.

Alum as referred to in the present invention is also called alum stone. The chemical composition is KAl3(SO4)2(OH)6. It appears as hexagonal plate-like or impression crystals, usually in the form of lumps or granules. It has a hardness of 3.5 to 4 and a specific gravity of 2.6 to 2.9. The crystalline form has a complete cleavage on the underside and a pearlescent luster on the cleavage surface. The bizarre ones have no luster. White or gray, sometimes red, yellow, or reddish-brown. Streak color is white. Insoluble in hydrochloric acid, soluble in potassium hydroxide or hot sulfuric acid. It is produced in volcanic rock that has undergone hydrothermal alteration.

The jade as used in the present invention is dense and hard, transparent and beautifully shiny, and polished to luster. Mineralogically, nephrite is a type of amphibole, and jadeite is a type of alkali pyroxene. Nephrite is often milky white, and there are also green, yellow, and red, and jadeite is green and white. There are various names depending on the color, but white jade and jade are the representative ones. It has been valued in the Orient since ancient times, and has been used as a decorative stone and jade ware. Nephrite is produced as pulses in crystalline schist or gneiss in Turkey and other places, and in the contact zone of granite in northeast China. Jadeite is produced in the form of veins in serpentine in Myanmar, and is also produced in Yunnan, China and the Tibetan Plateau. Jade in the narrow sense refers to jade, but the present invention is not limited thereto, and jade in the present invention is defined to include all of the above-described jade in the broad sense.

The composition includes a natural extract selected from the group consisting of a chives extract, a gentian extract, an infant child extract, and mixtures thereof.

The chrysanthemum (Juncus effusus var. decipiens) is also called sirloin grass, and grows in the waterside of fields or wetlands. It is 50-100 cm high. The rhizome is slanted to the side and has many short nodes, from which a flat green stem in the shape of a cylinder emerges. The stem is full, and the leaves are scaly, coming out from the base and enclosing the stem. Flowers are greenish-brown in May-July, hanging one at a time in raceme in the upper part of the stem. The bract at the bottom has a cylindrical shape, stands upright, has a sharp tip, and grows about 20cm in length following the stem, so it looks like the tip of a stem. There are 3 stamens, which are shorter than the inflorescence pieces, and the anther is the same length as the flower thread. The fruits are capsules, in the shape of a triangular egg, and ripen from September to October. The color is brown, the tip is blunt, and the length is the same as a piece of flower skin. The seeds are very small, about 0.5 mm long. It is widely cultivated in Japan, and it is used as a seat material for covering the tatami mats. It is also used as a material for cushions and mats. Herbal herb sirloin root is dried stems and is prescribed in oriental medicine for pain relief, diuresis, and hemostasis.

The gentian (Gentiana scabra Bunge) is a perennial herb that grows in the mountains and fields of the country, and is distributed worldwide in the eastern part of China, Japan, and the northeastern part of Russia. The rhizome is short, and there are many beard roots. Stems have 4 thin lines on the outside, are usually purple, and are 20-100cm high. The leaves are opposite and ovate. There are fine protrusions on the edge of the leaf and on the leaf line, so it is rough. One or several flowers hang from the tip of the stem and upper leaf axil in August-October, and are purple or rarely white. There is no flower stalk. The calyx is bell-shaped, divided into 5 parts. The end of the corolla is split shallowly into 5 branches, and there is a triangular branch of the corolla between the branches. 5 stamens and 1 pistil. The fruit is a capsule, and when ripe, it splits into two parts. It is planted as an ornamental and used medicinally.

The infant extract (Asyneuma japonicum BRIQ) is a perennial herb with thick roots, and the stems stand upright and grow to a height of about 60 cm. It is slightly branched near the tip of the stem, and coarse hairs are scattered all over the body. Leaves are alternately arranged at each node and have petioles. The shape of the leaf is in the shape of an elongated egg, with pointed ends at both ends, and the edge has sharp sawtooths. The tip of the branch turns into a flower stalk, and about 10 flowers form an inflorescence that looks like an ear, and blooms one after another from the bottom. The flower is deeply divided into five parts, and the split pieces are twisted and wound backwards. The size of the flower is about 2.5cm and the color is purple.
