Description

Mask equipped with oxygen generating function {MASK HAVING OXYGEN GENERATOR}

The present invention relates to a mask, and more particularly, to a mask having an oxygen generating function capable of supplying together oxygen generated from an oxygen generating agent and clean air in which fine dust is filtered from outside air.

In general, a mask refers to an article that covers a wearer's nose and mouth to prevent inhalation and scattering of germs and dust for hygiene. These masks have been used since the outbreak of influenza, a Spanish cold that became popular in 1919, and were developed for the purpose of preventing the phenomenon that when a person breathes cold air, the resistance in the nasal cavity or oral cavity decreases, increasing the likelihood of becoming infected with influenza. . In the case of the first developed mask, it was possible to prevent cold air from entering the human nasal cavity or oral cavity, but it could not filter out viruses or bacteria contained in the air, and thus could not prevent influenza.

Since then, various technologies have been developed to develop antibacterial masks that filter out viruses and bacteria contained in the air, and through this, influenza has been prevented. However, as various technologies were developed, an industry that applied the developed technology developed, which resulted in environmental pollution. Such environmental pollution is divided into air pollution, water pollution and soil pollution, among which air pollution includes fine dust with a particle size of 10 nanometers or less such as sulfurous acid gas, nitrogen oxides, lead, ozone and carbon monoxide.

Fine dust is a substance that has a great influence on the human body, and the danger of fine dust can be seen through the air pollution accident in Donora, Pennsylvania, USA in 1948, and the London smog incident, which killed approximately 4,000 people in 1952. . In particular, through research, it was found that fine dust having a particle size of 10 nanometers or less has a detrimental effect on the human body, such as increasing disease incidence and mortality. Since then, air pollution standards have been established to reduce the impact of fine dust on people and the environment to reduce the generation of fine dust, but since fine dust already contained in the air cannot be removed, it filters fine dust contained in the air. The technology was developed.

In particular, when a person does outside activities, a fine dust blocking mask has been developed that can filter fine dust while covering a person's nose and mouth.

First, the mask includes a mask body that is seated on the wearer's face to cover the wearer's nose and mouth, and a mask hanger strap that is coupled to both left and right sides of the mask body to be hooked to the wearer's ears. That is, the mask body is prevented from being separated from the wearer's face by hanging the mask strap on the wearer's ear. In the structure of such a general mask, it is widely known for changing the material of the mask body or for various adhesion structures of the mask hanger strap, and various types of masks are still commercially available.

In particular, a technique for blocking fine dust through a filter when the wearer breathes by installing various filters in the mask body to block fine dust is also widely known. However, the efficiency of blocking fine dust will vary for each mask, but it is obvious that wearing a mask will be much more helpful than breathing directly outside air without wearing a mask.

Recently, in addition to the effect of blocking fine dust, even a mask that directly generates and supplies oxygen through an oxygen generator has appeared. For example,'Oxygen generator-equipped mask' of Registered Utility Model Publication No. 20-0383904,'oxygen generating mask' of Registered Patent Publication No. 10-1737731, and'oxygen generator equipped with an oxygen generator' of Korean Patent Publication No. 10-2012-011450 Such as'mask'.
