The present invention relates to an integrated face protection device whose structure is improved so that a user's voice can be accurately transmitted to the outside by using a microphone as well as improving sealing properties along the fusion area of the face of the face.

In general, it is not an exaggeration to say that the daily life of modern people is always exposed to harmful substances. Industrial pollution such as soot caused by industrialization, fine dust floating in the air, and pollen causing allergy, yellow dust, severe acute respiratory syndrome (SARS), avian influenza (Avian influenza) Viruses such as AI) are causing serious environmental problems, such as causing various respiratory diseases.

Accordingly, air purifiers for purifying suspended harmful substances in the air have been developed and commercialized. These air purifiers are used for the purpose of purifying the air in a certain space, but there is a limit to completely purifying the toxic substances floating in the air, and because they are fixed to the ground or other auxiliary devices, they are not portable. In using it, there were many restrictions on use.

In emergencies where respiratory diseases are widespread, it causes a significant obstacle to daily work.Especially for face-to-face business workers, telemarketers, and medical workers, goggles and masks are worn for long hours to prevent droplet infection. In addition to being cumbersome and uncomfortable to wear, there is an inconvenience in communication due to inaccurate pronunciation of pronunciation or small voice during conversations and calls.

In addition, when the mask is worn for a long time, the earring band portion of the mask acts as a pulling pressure on the ear portion of the user, causing pain.

As a prior art related to the existing mask, as disclosed in Korean Patent Publication No. 10-1787486, "Face filter-type mask with improved airtightness" (registration date: Oct. 12, 2017), hollows penetrating the front and rear surfaces are formed. And a close contact pad that covers the respiratory tract while its rear surface is in close contact with the surface of the wearer's face; A mask body provided on the outside of the adhesion pad to block the hollow and filter contaminants; And a binding member having a binding frame surrounding the mask body and binding the mask body to the contact pad, wherein the binding frame includes: a binding ring coupled to an outside of the mask body; And a plurality of binding teeth connected to the binding ring and surrounding the surface of the mask body, wherein a through hole is formed between the binding teeth, and the binding ring has a plurality of non-slip protrusions on the surface in contact with the mask body Formed.

Accordingly, masks that are easy to carry are used, and existing masks have two general purposes: preventing impurities or contaminants from entering the wearer's breathing path, and pathogens and other contaminants exhaled by other people or objects. It is worn on a person's respiratory tract for at least one of the purposes of preventing exposure to.

In the first situation, the mask is worn in an environment where the air contains particles that are harmful to the wearer, such as in a car workshop.

In the second situation the mask is worn in an environment where there is a risk of contamination to other people or objects, for example in an operating room or a clean room.

These masks are classified as filtering facepieces because they themselves function as a filtering mechanism.

However, the conventional mask has a problem in that it does not properly adhere to the face surface according to various individual differences according to the face contour of the wearer, and does not satisfy the stability of wearing as well as sealing property, and it is necessary to wear goggles together to prevent splashing of splashes. There is discomfort in wearing.

In addition, in the case of wearers of goggles and glasses, since the exhalation of the user exhaling while wearing a mask is humid and relatively hotter than the outside air, there is a difficulty in securing the field of view due to fogging on the goggles or glasses.

As another prior art for improving this, as disclosed in Korean Patent Publication No. 10-1879792 "Fogging prevention and breathing improvement protective equipment" (registration date: 2018.07.12), a transparent window, which accommodates the transparent window, is disclosed. An outer frame, a safety goggle installed at one end of the outer frame, or formed in the inner, and made of a first filter filled with a plurality of zeolites to remove moisture; And a mask body portion in contact with the nose and mouth of the human body, a mask hanger portion formed on both ends of the mask body portion to be hung on the human ear, a filter housing portion formed on the mask body portion, and the filter housing portion, , A mask including a second filter filled with a plurality of zeolites to remove moisture; it relates to a protective device for preventing fogging and improving breathing.

In this case, the moisture removal zeolite is filled in the inside of the first and second filters, but there is a concern that moisture adsorption performance may be degraded due to the inflow of moisture from the outside at all times, and the performance can be maintained only by frequent replacement of new zeolites. There are drawbacks.

For this reason, even if the user wears the integrated protective equipment, there is moisture exhaled by the user, and the breath of hot exhalation causes the steam to form inside the transparent material, making it inconvenient to secure visibility.If you need to eat food or drink, the entire protective equipment is Since it has to be removed and worn again, there was a concern of abrasion on the user's face skin during the repeated wearing process or infection during the process of wearing the used protective equipment again.

In addition, the existing mask-type protective equipment, even if the infected person wears the mask, if the wearing time is prolonged, the performance may be degraded and the virus may leak to the outside, and a separate device or function to prevent this may not be implemented.

In addition, the existing mask-type protective equipment has a disadvantage that it acts as a disturbing factor when the user speaks, and thus improperly transmits the user's pronunciation, or interferes with the user's conversation or work by reducing the volume of the voice.

However, with the recent emergence of a new virus around the world and prevalence as an infectious disease, workers are required to wear respiratory protection in industrial sites, but there is a concern that users will avoid it if it is uncomfortable to wear due to the above various reasons. There is a concern that diseases of the respiratory system may spread.
