Description

DESCRIPTION

Helix filter mask

Technical sector

The present invention is located in the sector of security products for people (or other living beings) against pathogens that can enter the body.

Background of the invention

The physical protection elements that the market now has to reduce the risk of introducing elements that are harmful to health are manufactured from a filtering material that -being passed through by said pathogens- prevents the passage of said harmful agents into the tract. respiratory. Said filtering elements are shaped like a facial mask, adjusting in the area of the nose and mouth, two possible entry ways for said harmful elements. As a variant in order to reduce the discomfort of using these physical barriers that prevent fluid breathing when used in some types of masks, a valve is included, which allows the direct exit of exhaled air, although this is at the cost of losing the quality of filtering. outward.

Explanation of the invention

The invention that is now exposed, tries to avoid in an innovative way that pathogenic elements are introduced into our body through the respiratory or ocular route. This is achieved through a facial protective element -mask- that has several properties that make it innovative:

1. - It is made almost entirely of a transparent plastic material, which allows the face to be left visible, unlike conventional masks that cover it almost completely. Using a washable material also makes it reusable.

2. - It incorporates protection for both the nose and mouth and can also protect the eyes. Its design leaves a certain separation from the face under the nose to allow a direct flow of air to the bottom of the mask where the filter is housed, which is thus in front of the chin and under the mouth and through which by its bottom, finally, the air is exchanged with the outside. With all this we achieve, unlike conventional masks, to be able to enjoy fluid, direct and effortless breathing.

3. - As the most innovative component, the mask has a cylindrical filter with an internal helix duct. With this form we achieve both direct communication between indoor and outdoor air - which again translates into comfortable and effortless breathing for the user - and optimal filtering of the particles contained in aerosols in the air. which are glued to both the inner walls of the cylinder and the inner helix itself if the latter is also made of absorbent filtering material. Preventing pollutants from entering the inner cavity of the mask and being inhaled is achieved by the centrifugal effect that occurs when the fluid passes through the helical movement of the filter duct, thus retaining droplets and other particles when they come into contact with the walls. of the container cylinder by the centrifugal effect itself that occurs with said helical movement; Said pathogens are also retained in the helicoid itself if this is also carried out with filter material.

As a variant, electrical energy can be incorporated through a small battery so that the propeller automatically rotates in one direction or another depending on whether air is sucked in or exhaled and thus that air flow is favored even more, which would allow breathing effortlessly as if you weren't wearing a mask or even better. This is done through a small motor housed in the filter shaft and a pressure membrane switch that acts automatically in the direction of rotation that favors the inhalation or exhalation that the user of the mask is performing.

Brief description of the drawings

The drawings reflect two orthogonal views of the protection element placed on the face and a perspective image of the filter piece, externally cylindrical, with an internal helical shape:

Figure 1 shows front and side projection views of the mask that covers the eyes, nose and mouth. The filter has been graphed in section.

Figures 2 and 3 show a perspective and sectional view of the filter, showing the helical vortex through which the fluid moves and the outer cylindrical tube.

Preferred embodiment of the invention

The preferred material of embodiment for the construction of the mask itself will be transparent plastic resistant to breakage and anti-fog. The filter will be composed of a filter / absorbent material that allows to retain the pathogenic particles that come into contact with it.

Claims (6)

1. Filter mask characterized in that it comprises a helix-shaped filter element that: • It is made up of a cylindrical outer element and an inner one that forms a helical duct. • It is housed in the lower part of the protective face element. 2. Mask with filter according to claim 1 made of a transparent, washable, tear-resistant plastic material with anti-fog properties. 3. Mask with filter according to claim 1, wherein the material of the filter element that generates the helical shape is made of filter and / or absorbent material, such as the inner part of the cylinder thereof. 4.
