Description

Mask detachable anti-splash security surface{omitted}

The present invention relates to a mask detachable anti-splash security surface configured to be detachable from a respirator mask, and allows the mask and the security surface to be used in combination or separately depending on the situation, and inside the security surface of a transparent film that prevents splash, static electricity If a dust collecting filter that can efficiently collect fine dust or ultra-fine dust flowing into the respiratory tract due to occurrence is installed, the respiratory system can be reliably protected from fine dust or ultra-fine dust as well as efficient splash prevention when face-to-face. For.

In the case of Korea, due to geographical characteristics, yellow sand or fine dust floats in the air from deserts or loess areas in the center of Asian continents such as China or Mongolia, and then mass flows into Korea through the western wind, and the yellow sand includes silicon, lead, It contains heavy metals such as cadmium, which is very harmful to the human body.

In addition, in recent years, due to the rapid industrialization of China, fine dust and ultrafine dust generated from numerous factories and homes in China are being introduced into Korea in large quantities, and the frequency and concentration of occurrence are also rapidly increasing. Due to the industrial development and the spread of automobiles, a lot of fine dust and ultrafine dust are generated, causing great inconvenience in daily life, such as threats to national health.

In addition, the damage caused by various pollen and pine pollen that occurs from spring to early summer is also great.

When various pollen, including the above-described fine dust and ultrafine dust, enter the human body through the respiratory tract, the immunity rapidly decreases, causing respiratory diseases and disorders such as colds, asthma and bronchitis, and cardiovascular diseases and other cardiovascular diseases. It may occur, and there is also a problem in that various diseases such as skin diseases and eye diseases may also occur.

In order to solve the above-described problems, there is a situation in which the demand for a mask is rapidly increasing as a means for protecting the respiratory tract and the human body from yellow dust, fine dust, and ultrafine dust.

As is well known, masks are used to cover the nose and mouth in order to prevent inhalation and scattering of fine dust and germs for health and hygiene, and have been used since the outbreak of the Spanish cold, that is, influenza, in 1919 to the present day.

These masks are made of materials such as cotton or non-woven fabric, and because they prevent direct inhalation of cold air through the nasal cavity or oral cavity, it is possible to prevent colds. There is a problem that it is not effective in blocking harmful substances of very small size, such as viruses, bacteria, and fine dust, which are smaller than the pores formed between the tissues of cotton fabrics.

In addition, most of the masks made of non-woven fabric are disposable masks with built-in electrostatic filter, which greatly reduces the electrostatic efficiency due to breathing, that is, water vapor during use, greatly reducing the dust collection effect such as fine dust, and easily polluting such as odor generation. While it is severe, it cannot be worn for a long time or reused.

In other words, the disposable mask made of non-woven fabric has an electrostatic filter, that is, a Melt-Blown filter, built-in. The electrostatic efficiency decreases rapidly due to the generated water vapor, and if the mask is washed for reuse, the filtering effect cannot be expected at all.

Therefore, even for cotton masks made of cotton fabrics as well as non-woven fabric masks with a built-in melt blown filter, if breathing occurs while wearing, fine dust such as yellow sand with a diameter of less than 10 μm cannot be blocked at all. It becomes unpredictable.

Meanwhile, as respiratory-related viruses, SARS (severe acute respiratory syndrome), which originated in Guangdong, China in November 2002, and spread to the world within a few months, and Mer. Su (Middle East Respiratory Syndrome), and respiratory tract caused by a new type of coronavirus (SARS-CoV-2), which first occurred in Wuhan, China in December 2019, has spread throughout China and around the world, and is still spreading at an alarming rate to this day. There is an infectious disease, "Coronavirus Infectious Disease 19 (Corona 19)", and Corona 19 is known to be transmitted when droplets (saliva) of an infected person penetrate the respiratory tract or mucous membranes of the eyes, nose, and mouth. After an incubation period of about 2 to 14 days (estimated), fever (37.5 degrees), respiratory symptoms such as cough or shortness of breath, and pneumonia are the main symptoms (asymptomatic infection cases are rare).

Accordingly, the demand for masks is increasing exponentially to prevent and block yellow dust, fine dust, and corona 19 infectious diseases from various industrial sites, to general households and the whole people. It is also showing a security side to prevent this.

Since the above-described security surface is formed of a transparent thin film, it can be said that it is a very effective product to prevent splashes as it can prevent splashing of splashes on not only the person's face but also the other party during face-to-face consultation or conversations with many people.

However, since the above-described security surface is made of cloth or non-woven fabric and cannot be worn close to the face like a mask worn on a respirator, a considerable distance between the face and the security surface is inevitably maintained. In addition to preventing splash, it blocks or blocks fine dust or viruses. There is a problem that cannot be done.

Therefore, most people try to prevent splashing and dust or viruses by wearing a respirator, that is, a common mask covering the mouth and nose first, and then wearing the above-described security surface further in front of it.

On the other hand, masks worn on respirators are manufactured in several grades, so the filtration efficiency varies according to the particle size such as yellow dust, fine dust, and ultrafine dust, and the higher the grade, the higher the filtering efficiency of fine dust, but it is somewhat difficult to breathe during activities. Difficulty follows, and if the grade is low, breathing is somewhat comfortable, but the filtering efficiency of fine dust decreases significantly.

Therefore, in order to prevent splashing and block the inflow of fine dust or ultrafine dust, there is a problem in that it is necessary to wear a high-grade mask and a more security surface, which is very cumbersome and uncomfortable.

On the other hand, in recent years, many functional masks that can prevent or block fine dust or ultra-fine dust have been introduced, including Patent Registration No. 10-1639265 and Patent Registration No. 10-2129298, but these have a fairly complex structure, resulting in a considerable amount of manufacturing cost. Also, when wearing these, breathing is not made smoothly, and thus it is not smoothly distributed.

001. Korean Patent Registration No. 10-1639265 (registered on July 7, 2016) "Multipurpose mask for ultrafine dust" 002. Korean Patent Registration No. 10-2129298 (registered on June 26, 2020) "Functional fine dust mask"

It also aims to smoothly collect incoming fine dust or ultrafine dust.

In addition, the security surface can be attached to the respirator mask, so that when breathing after wearing it with the mask, the dust collecting filter primarily collects fine dust or ultrafine dust that flows between the face and the security surface, and the secondary dust collection is performed by the respirator. It is also aimed at maximizing safety through the secondary dust collection effect by allowing it to be made by a mask worn on the face.

A number of filter insertion holes are arranged up and down at the upper and lower sides of both sides of the security surface (that is, the part close to the nose and mouth when worn), and the dust collecting filter that generates static electricity is composed of elastic bands connected with insertion pins on both sides of the top. Therefore, there is a purpose to make it possible to adjust the height of the dust collection filter.

The dust collecting filter is provided with a mesh filter paper that generates static electricity on the front and rear surfaces, and a plurality of electrostatic filter yarns such as a hair dryer used to shake off dust are installed inside, or a layer of melt blown fabric that generates static electricity is provided. There is also a purpose to maximize dust collection efficiency by providing it in layers.

The present invention is a security surface (1) made of a thin and transparent film material that can be worn on the face to prevent splashes, so that both sides of the breathing mask (3) can be detachably attached to both sides of the surface (1) and the mask (3). It is composed of attaching and installing magic tape in a predetermined position of

Therefore, in the present invention, only the mask 3 or the security surface 1 may be worn on the face, and the security surface 1 can be further worn at the same time as the mask 3 is worn, so that the user selects and wears appropriately according to the field situation. There are features that can be done.

In addition, the present invention makes it possible to easily attach and detach a dust collecting filter that attracts and collects dust or fine dust around by static electricity on a security surface made of a thin and transparent film material worn on the face to prevent splashing. In the process, dust or fine dust can be naturally collected from the air flowing into the space between the security surface and the face, so that the wearer's respiratory system can be protected, and splashes from themselves and the face-to-face can be prevented as the purpose of the security surface. The configuration to be configured is the greatest feature of the present invention, and it will be described in more detail with reference to the accompanying drawings as follows.
