Description

Ozone mask with breath valve {OZONE MASK WITH EXHALATION VALVE}

The present invention relates to an ozone mask, and more particularly, to an ozone mask having a breathing valve capable of capturing ozone contained in air.

In modern cities, everyday life is led by changes in the natural environment such as climate change, desertification, yellow dust, and exposure to air polluted by artificially produced fine dust such as automobile smoke and factory smoke.

In particular, the bronchus is directly exposed to fine dust due to respiration, which is a trend that increases the occurrence of respiratory diseases such as cough, asthma, bronchitis.

As the harmful substances in the air increase, the number of deaths from respiratory diseases is gradually increasing. In particular, Seoul has higher dust concentration than other large cities due to the effects of fine dust and yellow dust.

According to information released by the Ministry of Environment Air Quality Annual Report 2013, as in many big cities in the fine dust concentration in Seoul 45μg / m ³ of about 1.5 times the level of about three times in London ^{18μg / m 3, LA 30μg /} m 3 It can be seen that high.

Therefore, it is necessary to protect the bronchus from various harmful substances such as fine dust and ozone, and many people wear masks when they go out for this purpose, and the demand for masks is steadily increasing.

Specifically, surface ozone is a very harmful substance to humans even at low concentrations such as 100 to 200 ppb. Recently, in large cities such as Seoul, the ozone warning or ozone warning is frequently required, but there is no special countermeasure against ozone. Fine dust can use yellow dust mask, but general mask cannot remove ozone, so the Ministry of Environment of Korea is looking for an alternative.

As shown in Figure 1 to 8, as a mask for blocking the intake of contaminated air worn on the face, the present invention includes a mask body 100, ozone trap member 300 and the breathing valve 600 Can be.

The mask body 100 may seal a portion of the front face while covering the nose and the mouth.

The mask body 100 may be manufactured using a cotton material which is excellent in breathability, has good absorption of moisture such as sweat, and can be reused after washing.

The ozone collecting member 300 may be inserted into the mask body 100 to collect ozone contained in the air.

The ozone collecting member 300 may collect ozone using water.

The ozone collecting member 300 may include a spunless nonwoven fabric 310 and a water pocket 320.

The spunless nonwoven fabric 310 may be inserted into a part of the dust filter member 200 by the frame 50 and the net 70 while being dry compressed or unfolded. That is, it may be inserted while being separated from the dust filter member 200 by the frame 50 and the net 70 in a part of the dust filter member 200 in a dry compressed state or in an unfolded state. In detail, the frame 50 and the net 50 may be made of a light and soft material such as plastic or PTFE. A portion of the ozone mask 10 other than the ozone collecting member 300 may be inserted with polyethylene (PE film). The polyethylene increases the efficiency of the dust filter member 200 and helps to equalize the outflow of air from the ozone mask 10. In other words, such a flexible support layer helps to prevent water from reaching the face surface, thereby reducing discomfort and spreading the water evenly.

Spunlace nonwoven fabric (Spunlace 310) is excellent in soft touch and moisture absorption, the most popular and inexpensive fabric, high essence content, and excellent use. The spunless nonwoven fabric 310 may be a coin tissue of viscose fiber material. Specifically, the spunless nonwoven fabric 310 is a raw material of a restaurant coin tissue these days, and the nonwoven fabric is made of viscose fiber, which is a natural pulp material. Its features include water and are harmless to the human body. Viscose is a yellowish, sticky liquid produced by treating wood or metabolic fiber with caustic alkali and carbon disulfide. It is used as raw material for artificial dogs, cellophane, or adhesives.

The water pocket 320 is spunless nonwoven fabric 210 which is inserted into the spunless nonwoven fabric 310 in a state of containing moisture and releases moisture by pressurization by external force so that the ozone contained in the air can be collected. Is at least one configuration provided.

That is, the user compresses and bursts the water pocket 220 so that the water contained in the water pocket 220 is discharged to the outside, so as to wet the dry compressed nonwoven fabric 210, and thus, the nonwoven fabric 210 that absorbs the moisture. Captures ozone contained in the air, thereby preventing mask users from inhaling ozone.

Four or more water pockets 320 are provided in pairs on both sides of the mask body 100 and may be used while adjusting the number according to the ozone value. Specifically, when the ozone of the ambient air is the highest, the user When the water pocket 320 is pressed, the moisture in the droplets will quickly spread to the spunless nonwoven fabric 310. The moisture can help capture ozone. If the level of ozone is not too high, the user can only press two water pockets 320, and if the level of ozone is very high, the user can press and use all of the water pockets 320.

Here, in the ozone, ozone is an allotrope of oxygen consisting of three oxygen atoms, and the element symbol is O 3.

It is a slightly blue gas at room temperature, but blackish blue when liquid, and dark purple when solid. It has a peculiar smell and can detect odors even if only 0.0002% by volume is present in the air. Ozone dissolved in water slowly decomposes. It is soluble in liquid nitrogen, carbon tetrachloride and chloroform and is absorbed by turpentine oil and cinnamon oil.

Surface ozone is produced through photochemical reactions in which nitrogen oxides and volatile organic compounds in the air react with the ultraviolet rays of sunlight. Therefore, it occurs mainly in spring and summer, and exceeds 100 ppb per hour in air, which exceeds the environmental standard. And when 120ppb, ozone warning is issued.

It spontaneously decomposes at room temperature to become oxygen, and manganese dioxide, platinum powder, etc. promotes decomposition. It has strong oxidizing power and oxidizes silver to silver peroxide, lead sulfide to lead sulfate, and sulfur to sulfur oxide.

Occurs when wireless discharge in dry oxygen or air.When red phosphorus slowly oxidizes in air or when oxygen compounds such as potassium permanganate and potassium dichromate are decomposed to concentrated sulfuric acid, water is decomposed to fluorine, Occurs with oxygen when decomposed at large current densities.

It also occurs when oxygen is heated, sulfuric acid electrolysis, ultraviolet rays, X-rays, cathode rays, etc. pass through the air, so it is also present in the air, such as high mountains, coasts, and forests, which are rich in ultraviolet rays. However, when present in large quantities it makes you feel uncomfortable.

It is used to purify air by decomposing oxygen in theaters, schools, hospitals, etc. It is used for disinfecting beverages by sterilizing action, bleaching and determining the structure of organic compounds.

Toxic to the human body, long-term inhalation of the respiratory tract should be careful. In addition, even if ozone exceeds environmental standards, people with bronchial asthma are very dangerous because they may have difficulty breathing.

Furthermore, it affects the elderly and pregnant women more sensitively. As the number of times that the ozone concentration exceeds the environmental standard gradually increases, the countermeasures are urgently needed.

Owing to the properties of ozone as described above, the demand for technology for removing or collecting ozone is steadily increasing.

In addition, the water pocket 320 may be filled with one of an aqueous solution of KI, CaCl 2, NaCl and NaClO₄ instead of water. That is, not only water but also any aqueous solution that is harmless to the human body can be used.

As shown in FIGS. 7 to 8, under the same conditions, the same two aqueous solutions and deionized water (DIion) deionized water (DIion water) pass ozone through a wet coin tissue to remove ozone over time. Was tested. As a result, the removal efficiency was higher in the order of CaCl ₂ aqueous solution> NaCl aqueous solution >> DI water without ion after about 8 minutes.

Therefore, it was found that using an aqueous solution containing the above salts (aqueous solution containing CaCl ₂ , NaCl, NaClO _4, etc.) rather than simple water was more reactive and thus helped to remove ozone.

In addition, since the water pocket 320 of the ozone mask 10 uses an aqueous solution as described above, it is expected that the water pocket 320 may cope with a gas accident even in a disaster such as a Daegu subway fire or other Milyang Sejong Hospital fire accident.

The breathing valve 600 may be installed at a portion of the mask body 100 to reduce a pressure drop occurring in the ozone mask 10. The breathing valve 600 may be a one-way breathing valve that is controlled to open and close by pressurization by external force and is capable of exhausting only.
