KR20220033700A - Nose-mouth dustproof gas half face mask - Google Patents

Abstract

The present invention relates to a nose-mouth dustproof/gasproof half-face mask which is researched and invented to improve a respiratory device for workers working in an environment that is vulnerable to dust, smoke, odor, harmful gases and the like generated in various industrial sites and to prevent more powerful pathogens than viruses such as Coronavirus Disease (COVID-19) virus or MERS-CoV. To explain in more detail, gas masks that are currently commercialized are inconvenient to use in industrial sites. The present invention is to suggest a product that is capable of solving those inconveniences and that can be easily handled at any workplace, and that has high safety. As a canister is directly inserted into a nasal inlet inside the nose-mouth half-face mask, an operator can freely perform facial activities, and there is no risk of the canister falling out even during intense activities such that the safety level is high. On the other hand, the entire half-surface mask is made of a non-toxic and heat-resistant silicon material, thereby being safely usable in a hot work site. The half-surface mask can be worn in the same way as a regular mask, and is convenient to use since a hair strap for protecting a silicone earring rubber band and an earring rubber band can also be arbitrary adjusted at a wearer. Since there is a preliminary filter, change of an auxiliary filter can be easily done even when the auxiliary filter is destroyed by a lot of dust. The half-surface mask is economically beneficial since the canister can be removed and washed in hot water after work so as to be reused. With the above features, the nose-mouth dustproof/gasproof half-face mask protects the health of workers at industrial sites that handle hazardous substances and can be supplied at a relatively low price.

Description

Nose-mouth dustproof gas half face mask

The technology of the present invention relates to breathing inhalation equipment that is essential in various work sites where dust, odor, and soot gas are generated. it's about It is a technology related to the invention of a nose-type dust-proof and respirator mask that is economical, reduces resource loss and helps the environment by improving the inconvenience of currently used disposable masks or gas masks, and separating and washing the purification tank after use.

In general, a cotton mask or cotton towel is often used as a suction protector in a foundry that deals with fine powder, stone dust, or a Pahu factory for metal surface treatment. There is this. To solve these problems, we would like to provide a nose mouth dustproof and respirator half mask tailored to the worker's environment.

In order to block various kinds of organic substances that are harmful to the human body or bacteria mixed in the air, activated carbon, which is already used in gas mask purifiers, was used. It is a mask that enhances the effect of dust and gas prevention by inserting a filtration filter and a water-blocking purifier so that it can be replaced at any time according to the user's needs.

Even if there are many industrial sites that produce inhaled substances that are harmful to the human body, there are very few masks or gas masks suitable for each site. You can often see the scene.

We aim to maximize the safety of workers by providing customized anti-dust and respirator masks to these industrial sites. It is a technology that can improve the working environment and increase economic efficiency by supplying a dustproof and respirator mask that can be commercialized as a breathing device that is easy to handle and can be reused.

While currently commercially available masks are inconvenient to use in industrial fields and there are many points to be improved. Therefore, we intend to solve this problem by providing a dust-proof and respirator mask that is easy to handle and has high safety in any workplace. The features of the present invention will be described in more detail as follows.

★ On the other hand, the full gas mask or gas mask does not go through the purification tank and is inhaled if there is a place where it can be inhaled. On the other hand, the present invention is characterized in that it is blocked from the external suction port by inserting the purification tank inside to be directly connected to the nose suction port. Only the purified air that has passed through the purifier is sucked in.

★ It is a complete separation means to prevent external inhalation at the nose inlet and mouth outlet. On the other hand, a double inhalation barrier is installed inside the whole to block suction and only discharge through the mouth. It is discharged only through the exhaust valve.

★ The device to wear the dust and gas mask is more important than anything else. It should be easy to wear, and the wearing part should be stable and the adhesion degree maintained accurately so that there should be no change even if the wearer moves violently.

The present invention can be worn in the same way as a general mask, and the wearer can adjust the earring silicone rubber band and the headband protecting the earring rubber band. A single piece of earring rubber band was wrapped around the purification tank and hung on both ears, gathered under the chin, and the installed rubber band was pulled to stably adjust the strength of the pressure on the face.

★ A moisture-proof and heat-resistant non-woven fabric is attached to the inner surface of the mask to absorb moisture generated by breathing and moisture generated by the temperature difference between the cold air and the face. Non-woven fabric is a device that can be exchanged frequently.

★ On the other hand, since the whole is made of non-toxic and heat-resistant silicone material, it can be used safely even at worksites with high heat.

★ It is hygienic and economical because it can be reused by removing the purifier after working in a poor working environment and washing it in hot water.

★ The purification tank is a lightweight aluminum square tube that adheres to the bottom of the nose, and connects the auxiliary filter cover to the suction port at the bottom of the purification container to prevent it from falling off due to snoring. It is easy to replace and prevent dropping of the purification tank by combining it with its own rubber case.

★ Even if the auxiliary filter is destroyed in a place where a lot of dust is generated like a foundry, it can be easily replaced with a spare filter.

It relates to an invention for providing a nose mouth dustproof and respirator half mask that can protect the health of workers in an industrial field dealing with hazardous substances with the above characteristics.

The core technology of the present invention is to require a dustproof and gas mask to filter out pollutants that are harmful when inhaled in breathing and living the air on Earth, which is the basis of human activity and life.

Disposable masks or cotton masks are mainly used to filter fine dust and artificially generated dust with a filter, and gas masks are mainly used in places where harmful organic compound odors and harmful gases and fumes are generated. In industrial sites, there are many places where dust and gas are generated at the same time, and there are many places where it is necessary to wear it all the time rather than temporarily. However, the currently available dust mask or gas mask has limited effectiveness or is inconvenient to use for a long period of time in the workplace, so the nose mouth dust and gas mask was devised so that the wearer can use it hygienically and stably by improving these points.

This dust-proof and respirator mask is not only needed in industrial sites. It can be used for CBC or biochemical warfare education, and can also be used as a first aid kit in case of fire. It is a dust and gas mask that is not only necessary as work equipment, but is also worth developing as an emergency equipment with the effect of protecting lives.
