    Invention background
    The present invention relates to the field of diving masks, and in particular the masks used for underwater hiking, also called PMT (Palmes-Masque-Tuba), in English "snorkeling".
    This underwater hiking activity allows you to observe the seabed while swimming on the surface of the water. The underwater hiker must therefore be able to keep their head underwater while breathing. Generally, the underwater hiker is equipped with a mask for vision, and a snorkel for breathing. The tuba consists of a tube, the lower end of which is provided with a buccal portion which is housed in the mouth of the user, and an upper end allowing both the admission of fresh air and the exhaust of expired air.
    It is known that such equipment has many drawbacks. First, because breathing through the mouth is not natural, some people find it difficult to breathe orally using a snorkel. Another is that it is not possible to speak underwater when you have a snorkel in your mouth.
    Yet another drawback, linked to the use of the mask, is that the inner wall of the visor generally tends to be covered with fogging, which impairs good visibility, and which forces the user to regularly clean his mask. The appearance of fogging is due to the fact that the user's nose opens into the vision chamber located between the visor and the user's eyes, and in general to any hot air produced in the vision chamber without being renewed with fresh air.
    Also, the use of this mask-snorkel device is not very comfortable.
    To overcome this drawback, the document FR 3 020 620 B1 proposes a diving mask making it possible to breathe through the nose and the mouth.
    However, this type of improved snorkel mask does not allow the user to compensate for the pressure when going deep. To perform this operation, it is necessary to pinch the nose in order to plug the nostrils and balance the pressures at each ear (in particular between the outer ear and the middle ear of a given ear).
    There is thus a need for a snorkel mask making it possible to breathe indifferently through the nose and / or the mouth, avoiding the formation of fogging in the vision compartment and making it possible to carry out as many times as necessary a pressure balancing operation.
    There is also a need for such a snorkel mask which is light, easy to position on the wearer's face, and comfortable.
    Subject and summary of the invention
    The present invention overcomes the aforementioned problems in that it relates to a diving mask comprising: a. A body provided with a visor comprising an upper part, and a flexible skirt comprising a partition delimiting an upper chamber for the vision of a lower chamber for breathing, the partition being arranged to be supported above the nose of the user so that the mouth and the nose of the user are in the lower chamber, while the eyes of the user are in the upper chamber, the partition comprising at least one passage arranged to allow circulation fresh air between the upper chamber and the lower chamber during a user inspiration phase, b. a tuba arranged in extension of an upper part of the body, the tuba comprising at least one air duct; vs. the body comprises an exhaled air exhaust device which fluidly connects the lower chamber with the air duct of the snorkel.

    In an alternative embodiment, the tuba comprises a single air duct which is in fluid communication with the lower chamber and the upper chamber.
    This arrangement simplifies the design and manufacture of the tuba, compared to the tubas of the prior art comprising several channels. Advantageously, the entire interior volume of the snorkel is available during the inspiration and expiration phases, which makes it possible to significantly increase the flow of incoming and outgoing air, thereby improving comfort and facilitating bucco-nasal breathing. The single air duct is therefore in fluid communication with the expired air exhaust device, and also with the fresh air intake device.
    Preferably, the single air duct is in fluid communication with the first and second exhaled air exhaust channels.
    Alternatively, the snorkel used in the mask according to the invention may comprise several channels although this is not preferred.
    In a variant, the partition comprises at least one non-return valve, in particular a non-return valve, arranged to allow only a flow of fresh air directed from the upper chamber to the lower chamber during an inspiration phase. of the user.
    It is understood that the non-return valve, in particular the non-return valve, opens during an inspiration phase and closes during an expiration phase.
    The non-return valve or the non-return valve thus has the function of preventing the exhaled air from flowing towards the upper chamber, thus preventing the appearance of fogging on the lower face of the upper part of the visor. .
    According to one embodiment, the non-return valve comprises a flexible flap consisting of a part of the flexible skirt.
    Preferably, the flexible flap of the non-return valve consists of a portion of the partition.
    The flexible shutter is preferably delimited between a free edge of the partition and a cut made in the partition.
    This cut gives the flexible shutter mobility allowing it to bend during an inspiration phase so as to open the passage and allow fresh air to enter the lower chamber.
    Preferably, during an expiration phase, the flexible flap bears against the visor in order to close said passage.
    The present invention also relates, according to a second aspect, to a method of manufacturing a diving mask, as defined according to any one of the variant embodiments defined above with reference to a first aspect of the invention. .
    Said method comprises the following steps: a) injection of a visor comprising a central opening, b) overmolding of at least one main nasal part as defined with reference to a first aspect of the invention, engaging at least with the upper and lower edges of the central opening, c) assembly of a skirt as defined with reference to a first aspect of the invention, on the assembly obtained at the end of step b), d) obtaining a diving mask.

    The first non-return valve 43 also includes a valve seat 144 arranged to cooperate with the flexible membrane 142, the valve seat being integrated into the visor 20. In the closed position, the flexible membrane 142 is supported on the valve seat 144 for closing said at least one opening formed in the first exhaled air exhaust channel 81.
    The exhaled air exhaust device 80 also comprises a second non-return valve 160, similar to the first non-return valve 43, which is arranged to allow a flow of exhaled air directed from the lower chamber 50 towards the conduit d air 72 from tuba 70 during a user expiration phase. The second non-return valve 160 functions like the first non-return valve 43.
    The flexible skirt 30 having first 51 and second 52 lateral parts arranged so as to seal the first and second exhaled air exhaust channels 81 and 82.
    In operation, the user has the mask 1 on his face, which may include fixing means such as elastic straps adjustable in length. When the user inhales, the fresh air inhaled passes through the duct 72 of the tuba 70 and opens into the upper vision chamber 45 then passes through the passage arranged by means of the non-return valve 55 in the partition 40 to open into the lower breathing chamber 50 in which the user's nose and mouth are located. The non-return valve 55 is configured to allow the air inspired from the vision chamber 45 to the breathing chamber 50 and prevent any return of expired air in the opposite direction. During an expiration phase, the air passage in the partition 40 is closed so that air is forced into the first and second air exhaust channels 81 and 82 arranged along the side edges 2 and 3 of the body 10, in particular arranged along the lateral edges of the visor 20 and closed in a sealed manner by the corresponding lateral edges of the flexible skirt 30.
    The first and second exhaled air exhaust channels 81 and 82 are in fluid connection in their upper parts with the tuba 70, in particular with the single air duct 72. The exhaled air is therefore evacuated towards the tuba 70 without passing through the upper vision chamber 45.
    In order to balance the pressures, the user pinches his nose, by housing his fingers in the recesses 31 and 32 of the main housing 16. The auxiliary housing 62 being fitted into the main housing 16, the pressure exerted on the main housing 16 is transmitted to the auxiliary housing 60, which transmission is facilitated due to the protrusions 5 and 6 of the main housing pressing against the protrusions 90 and 91 of the auxiliary housing 60. The nesting of the main housing 16 and auxiliary 62 facilitates the pinching of the nose.
    In addition, the arrangement of the visor 20 in front of the mouth, as well as the overmolding of the main nasal part 15 on the opening 4, and its arrangement relative to the auxiliary nasal part 60 allow the nasal parts 15 and 60 not are not found against the mouth of the user which facilitates breathing.
    The main nasal part 15 being overmolded at the lower edge 21a of the upper part 21 of the visor 20 on the one hand, and at the upper edge 22a of the lower part 22 of the visor 20 on the other hand, and possibly at the lateral edges 20d of the visor 20, there is no risk when the user manipulates it that it becomes detached from the visor 20.
    The mask 1 according to the invention thus makes it possible to combine the advantages of an anti-fog mask allowing breathing indifferently through the nose and the mouth, while being able to balance the pressures at the level of the ears.
