A diving mask (1) comprising a rigid frame (10) having a front perimeter edge (11a) and a rear perimeter edge (11b). The rigid frame (10) provides an upper portion (12) and a lower portion (13) connected by a first and a second lateral portion (14a, 14b). The mask (1) provides, furthermore, a visor (20) made of a transparent material and fixed to the rigid frame (10) and an inhalation duct, or snorkel, (30) for inhaling the air during inspiration. Inside of the rigid frame (10) a face member (40) is fixed that is made of a soft and flexible material configured to be arranged, in use, in contact with the user's face. A partition member (43) divides the volume between the visor (20) and the face member (40) in an upper chamber (21) pneumatically connected to the inhalation duct, or snorkel, (30) through at least an opening (44), and in a lower chamber (22) arranged to house, in use, the nose and the mouth of the user. A discharge duct (60) pneumatically connects the lower chamber (22) with at least an exit mouth (75) for the exit of the exhaled air that is made at the rear perimeter edge (10b) of rigid frame (10).

The mask for surface snorkeling comprises a rigid frame (2), a transparent visor (3), a soft face mask (4) applicable in an airtight way to the face of the user and having a membrane (7) which delimits an upper viewing chamber (8) being shaped to contain the eyes of the user and a lower breathing chamber (9) being shaped to contain the nose and mouth of the user, and a breathing circuit (5) connected to the lower chamber (9), a ventilation circuit of the upper chamber (8) independent and separated from the breathing circuit (5) also being provided.

A full-face mask, including a mask body, a breathing tube, an unfolded isolation support portion, at least one intake valve and at least one isolation plate, is provided. The mask body fits an user's face via a soft portion to form an interior space. The breathing tube is disposed on the mask body and is connecting with the interior space. The unfolded isolation support portion is disposed in the inner space and completely fits and covers the cheeks and the nose of the user to define an upper space and a lower space. At least one intake valve is disposed on the unfolded isolation support portion. A guide plate is disposed in a channel. Thus, the user could effectively breathe and exhale the air, and could isolate the face from the water leaking into the full mask to avoid danger.

A full-face diving mask includes a mask and a breathing tube. The mask includes an outer frame, a lens housing and a fitting mask. The fitting mask includes a partition plate. The partition plate and the inner surface of the lens housing define an observation chamber on the top and a breathing chamber below. The partition plate includes at least one air intake port to allow inhaled air to be guided and circulated through at least one air intake passageway from the observation chamber toward the breathing chamber. The breathing chamber is further provided with an air compartment partition plate connected to the partition plate to define an air discharge compartment. The air compartment partition plate is provided with at least one air discharge port to allow exhaled air to be guided through at least one air discharge passageway from the air discharge compartment and discharged along the breathing tube.

The invention discloses a snorkeling breathing apparatus comprising a mask, a first breathing tube assembly and a one-way exhaust valve. The mask comprises an outer mask and a breathing mask provided within the outer mask and, equipped with a breathing chamber. The breathing tube assembly comprises a first breathing tube and a one-way inhaling valve. The breathing tube is connected to the breathing mask through the inhaling valve. The exhaust valve is connected and mounted on the outer mask and the breathing mask. While inhaling, the inhaling valve conducts and air enters the chamber through the breathing tube. While exhaling, the exhaust valve conducts and air flows from the chamber to outside. The invention aims at making an innovation to the breathing system by separating, the exhalation and suction mechanically, to make sure air in the breathing cavity is always fresh, and to increase the safety performance.

A full face diving mask having a transparent visor (2), a frame or strapping (3), a sealing skirt (4) to ensure the water-tight seal, and suitable straps (5) for fitting the mask on the user's face. The mask has a breathing tube (6) which engages on the tipper part of the mask and which allows the flow of air to enter into the compartment made between the frame and the visor. The breathing tube is made with separate ducts for the air inhaled and exhaled and the inside of the mask is made with two compartments, an upper main compartment (26) and a lower oronasal compartment (7) separated by a separating wall.

An improved hydrodynamic sports snorkel for use in swim training, exercise and other recreational activities, which facilitates efficient swimming by eliminating the need for a swimmer to turn their head to the side for breathing. The sport snorkel device provides a novel design that significantly reduces drag and resistance, including by directing breathing tubes down the sides of the chin and under the jaw line toward the neck, around the neck and rejoining and going to the surface at the back of the neck behind the swimmer's head. This novel design with tubes running under the jawline and behind the head significantly reduces the portion of snorkel tubing directly in the water flow stream and thus reduces drag and resistance. The sport snorkel device also allows the swimmer to hold the snorkel solely by the mouthpiece without the need to fixedly attach the device to the swimmer's head or goggles.

The present invention discloses a foldable breathing mask, comprising: a mask body and a breathing tube, wherein the top end of the mask body extends upwardly to form a connecting tube, and one side of the connecting tube and the corresponding side of the breathing tube are respectively provided with a hinge mechanism, such that the breathing tube is turned over downwardly to be flatly attached to the mask body or turned over upwardly to be communicated with the connecting tube, the other side of the connecting tube corresponding to the hinge mechanism is provided with an elastic hook, and the breathing tube is correspondingly provided with a hook groove or a hook opening. The foldable breathing mask has the advantages of quickness in folding and convenience in assembling.
