Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an anti-contamination mask having improved construction and advantages.

Conventionally, in the field of anti-pollution masks to which the present invention pertains, any mask used in the military or industry is used for purifying or purifying air to obtain breathable air from contaminated air or air in a contaminated environment. One example of a number of disadvantages is that breathing through conventional masks, which is experienced without a mask under normal atmospheric pressure drug conditions, is difficult for a person's inhalation and exhalation muscles. cloataphobia, or a feeling of being inhibited, primarily because it requires greater effort. The added strain placed on the person and the tightness of the mask over the nose and mouth often results in discomfort and general discomfort. Also, due to the added strain on the body of a person who wears a typical gas or pollution control mask, people with more sensitive lungs or bronchi5, e.g. those with varying degrees of asthma, etc. People are unable or unable to wear such conventional gas masks.

Obviously undesirable. Also, using conventional gas masks,
With the accompanying normal operating efforts of the human respiratory system, it is not always possible to obtain the desired or sufficient amount of air or oxygen, the lack of which increases one's sense of frustration, and Reduces the mental and/or physical efficiency of the mask wearer. Furthermore, there are situations such as those at high altitudes, where conventional pollution control or gas masks are
Because the ambient air is thin, it is unsuitable for climbers, aviators, etc. This also applies to people in other locations and conditions, such as in conditions in mining operations such as coal, or in smoke conditions often encountered by firefighters, for example.

The object of the present invention is to obtain a novel anti-contamination mask that overcomes one or more of the difficulties and drawbacks of the general types mentioned above, and
The aim is to obtain new advantages that were not available before.

Another particular object of the present invention is to obtain an anti-contamination mask that can provide improved breathing capacity under many different conditions and situations.

Another special object of the invention is to provide an anti-pollution mask that is equally suitable for use by any and all people.

Another object of the invention is to provide for easier breathing and a higher concentration of breathable air or oxygen per unit of breathable gas or air. The objective is to obtain an improved pollution prevention or gas mask.

Another object is to obtain an improved pollution control or gas mask of small, convenient and portable size and nature, as far as all operable and necessary parts and elements are concerned.

Other objects will become apparent from the foregoing and below disclosure.

One or more objects of the invention are achieved by the invention set forth in the foregoing and following disclosures and the accompanying drawings.

The foregoing purpose is to provide a mask that can be sealably and operably mounted on or around a person's face with respect to the person's mouth and/or nose, and that the person A gas mask with a surface structure that allows breathing only purified air and the attached fungi attached thereto; and an air purification mechanism installed above these and used to remove contaminants from the air passing through it; and - a large number of layers. compressing the volume of gas to a smaller volume and passing the contaminated air or gas through the air purification mechanism, so that the compressed purified air is delivered to the breathing side of the mask for respirator breathing; This is accomplished with a contamination control mask that includes a separate electrically operated gas compressor mechanism.

In a preferred embodiment, the pollution control or gas mask includes an electric motor associated with the gas compressor for driving the gas compressor. More preferably, the electric motor is combined with a battery and its circuit, and in this case, the electric motor is of a type that can be driven by a battery, and is capable of operating, stopping, and changing the speed of the compressor. It has switch elements that perform all or any of the above, and is entirely portable.

The air compressor is preferably arranged in series behind an air purification mechanism, e.g. contaminated air is drawn into or forced through the air purification mechanism, and then the purified air is transferred to the air compressor. Flowed to the vacuum side, thus only purified air is compressed and exhausted from the air compressor to the air breathing side of the mask.

The air compressor is designed so that the exhaust compressed air can, for example, be easily inhaled, but not at excessive, undesirable, or harmful pressure, which can harm the lungs, etc., of the person who is inhaling the air. The pressure is only slightly higher than atmospheric pressure, but sufficiently increased so that it is not too high and not so high as to unduly inhibit the exhalation of the mask wearer. It is adjusted to operate and function at a compression ratio such as pressure.

Next, a preferred embodiment of the present invention will be described. The invention will be better understood with reference to the accompanying drawings.

Although the anti-pollution mask of the present invention is used for similar purposes as conventional gas masks, its primary utility is for use in smoky environments, such as for firefighters, as described above. for use in industry, including the use of, and for the protection of workers in dusty or contaminated or infectious or chemically hazardous air or environments. As far as the use of a smoke environment is concerned, it not only makes breathing easier and more comfortable for rescuers.

The dual benefits of eliminating smoke and enriching breathable oxygen or air in such a smoky environment where high concentrations of carbon dioxide and carbon oxides are present are achieved. However, especially in the event of an accident or stroke, the timely and rapid use of the electric air compressor, which is part of the above-mentioned mask, may require even more elaborate treatment for rescued survivors or heart attack patients. Until then, there will be a small way to save the victim's life. Similarly, when used at high altitudes, the oxygen concentration in the air available per unit volume of space is low, and less oxygen is available to the brains of pilots, construction workers, mountaineers, etc. However, by using the electric mask of the present invention, the acuity of one's ejaculation is increased due to the availability of enriched air or oxygen, and at the same time due to the compressor. Although very small, the forced introduction of air or oxygen helps - z b Breathing becomes easier.

While one major aspect of the novelty of this invention is the presence of an electric compressor in the mask for breathing ambient air, other key features include the electric motor drive and its battery powered nature. , as well as in small portable batteries. However, at the same time, a special series arrangement for first passing or purifying the air before compressing the purified air is also novel, in this case eliminating contact of contaminants with the compressor, and This has the advantage of making more efficient use of the air and enriching only the breathable purified air. As mentioned above, in such an arrangement, the exhaust or vacuum side of the compressor serves to draw environmentally contaminated air through the air cleaning structure and mechanism. The compressor sucks and compresses contaminated air, and the compressed contaminated air is directly
Although it is within the scope of the present invention to discharge to an air purifier and thus force the highly contaminated air through the compressor through the compressor, the other arrangements described above are within the scope of the present invention. is more preferable for the reasons stated above. Similarly, the advantage of the preferred mask described above is that it does not obscure the eyes, thus giving the eye an improved feeling of being free and unencumbered, if the eye protection reservoir is made of transparent plastic or glass. This can also be achieved by providing a full face mask with However, masks that also cover the eyes are often difficult to see and can actually hinder or help the mask wearer.
