Description

DESCRIPTION

Protection mask

TECHNICAL SECTOR

The present invention refers to a face protection mask, of the type used as a means of protection against viruses, bacteria, germs, dust, pollution, etc.

The object of the invention is to provide a mask that is comfortable to use, safe, capable of being worn for long periods of time, by virtue of a structure that prevents the inhalation of carbon dioxide expired by the user, inhaling filtered air, as well as other advantages such as avoiding lens fogging for users who wear glasses.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, that of protective masks against viruses, bacteria, germs, dust, pollution and the like, although there are masks with a high degree of filtration of the air that passes through the mask, the problem they present is that part of the exhaled carbon dioxide is not expelled through it, being inhaled again, with the consequent risk of hypoxia that this entails.

Another common problem in masks is that part of the hot exhaled air flows superiorly through the upper edge of the mask, causing people who wear glasses to fog up the lenses, with the consequent loss of visibility.

These problems are accentuated when a mask is worn during sports.

EXPLANATION OF THE INVENTION

The recommended facial protection mask fully satisfactorily solves the aforementioned problem, in all the aspects mentioned.

For this, and starting from the conventional structuring of a reusable mask, in which an air filtering body is defined, based on neoprene, polyester, cotton, elastomers, or a mixture of them, with dimensions that allow covering from the nose to the chin area of the user, and including any conventional fixation means, the mask of the invention focuses its characteristics on the fact that internally it includes a diffuser that determines a transverse partition of a flexible nature, whether based on PVC, silicone, TPU, rubber and / or other flexible and hygienic materials, so that said diffuser adapts to the physiognomy of the user's face in the intermediate area between the nose and the mouth, determining two independent chambers, an upper chamber inhalation through the nose, and a lower exhalation chamber through the mouth.

From this structuring, it is prevented that the exhaled carbon dioxide can be inhaled again, by forcing it to go out to the outside of the mask, said diffuser acting as a watertight barrier against it.

This not only ensures the inhalation of clean and filtered air, which is essential when practicing sports or wearing the mask for long periods of time, but also prevents the hot exhaled carbon dioxide from rising higher towards the eye area. of the user, which is especially important for people who wear glasses, thus preventing the lenses of the same from fogging up.

The diffuser will be fixed to the internal face of the mask by any conventional means, thus obtaining a mask that is extremely comfortable to use, safe and reusable, washable at a maximum temperature of 60 ° C.

As is evident, the mask of the invention will only be effective as long as the user inhales through the nose and exhales through the mouth.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

Figure 1.- Shows a transparent side perspective view of a face protection mask made in accordance with the object of the present invention, duly applied to the face of a user.

Figure 2.- Shows a perspective view of the mask of the invention.

Figure 3.- Shows a plan view of the mask.

Figure 4.- Shows a profile view of the mask.

Figure 5.- Shows a front elevation view of the mask of the previous figures.

Figure 6.- Shows, finally, a rear elevation view of the mask.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the face protection mask of the invention is materialized, as is conventional, from a body (1) acting as an air filter element, which can be obtained in different materials, of analogous to conventional reusable masks, such as neoprene, polyester, cotton, elastomers, or a mixture of them.

The body (1) has dimensions that allow covering from the nose (2) to the chin area (3) of the user, so that in the chosen embodiment it is later finished off in a pair of adhesive strips (4), without ruling out other conventional means, such as fixing means around the ears of said user.

In any case, and in accordance with the essence of the invention, it has been envisaged that on the internal face of the mask, and in correspondence with the area between the nose (2) and the mouth (8) of the user is established a diffuser (5) in which a transverse partition (6) of a flexible nature is established, whether based on PVC, silicone, TPU, rubber and / or other flexible and hygienic materials, a set that adapts to the physiognomy of the The user's face in the intermediate area between the nose and the mouth, determining two independent chambers, an upper chamber for inhalation through the nose, according to the arrows shown in Figure 1, and a lower chamber for exhalation to through the mouth.

The diffuser can incorporate in its lower zone, or exhalation zone, some deflectors (7) that redirect the exhaled air in a lateral-inferior direction, so that once the filter material of the mask has passed, said carbon dioxide remains as as far as possible from the suction zone of the user.

Claims (2)

1st.- Protection mask, which being of the type constituted from a body (1) obtained in an air filter material, reusable, body (1) intended to cover the area of the user's nose and mouth, counting with fixing means to the user's head, it is characterized in that a diffuser (5) is established on the inner face of the mask, and in correspondence with the area between the nose (2) and the mouth (8) of the user. in which a transverse septum (6) of a flexible and hygienic nature participates, adaptable to the physiognomy of the user's face in the intermediate area between the nose and the mouth, determining two independent chambers, an upper inhalation chamber through of the nose, and a lower exhalation chamber through the mouth. 2.- Protective mask, according to claim 1, characterized in that the diffuser (5), in correspondence with the area of the user's mouth, incorporates deflectors (7) for directing the exhaled air in a lateral-inferior direction.
