In an embodiment of the present invention, the scuba 1 comprises a mask 10, a first breathing tube assembly 20 and an exhalation check valve 30. Wherein the mask 10 comprises an outer mask 11 and a breathing mask 12, the breathing mask 12 is arranged in the outer mask 11, and the breathing mask 12 is provided with a breathing cavity 121; the first breathing tube assembly 20 comprises a first breathing tube 21 and an inhalation one-way valve 22, the first breathing tube 21 being connected to the breathing mask 12 by the inhalation one-way valve 22; alternatively, the inhalation check valve 22 is arranged in the first breathing tube 21, and the first breathing tube 21 is connected with the breathing mask 12; the expiration one-way valve 30 is connected with the outer cover 11 and the breathing cover 12; when inhaling, the inhaling one-way valve 22 is conducted, and the outside air enters the breathing cavity 121 from the first breathing tube 21; during exhalation, the exhalation check valve 30 is closed, and the exhaled air flows from the breathing chamber 121 to the outside of the outer cover 11.

In particular, the mask 10 is intended to be worn to assist in the free breathing of a person under water. Mask 10 includes an outer mask 11 and a respiratory mask 12. The outer mask 11 is mainly used for protecting the face, and generally, the outer mask 11 is integrally made of a transparent material so as to have a better visual field in water, and of course, only the parts corresponding to eyes can be made of the transparent material, so that the shape is changeable. The breathing cover 12 is arranged in the outer cover 11 and used for breathing and wearing, the breathing cover 12 is provided with a breathing cavity 121, when the breathing cover is used, breathing is carried out through the breathing cavity 121, meanwhile, the breathing part is separated from eyes through the breathing cover 12, and the effect of breathing gas and the generation of fog on the outer cover 11 are avoided, so that the visual field is influenced. Preferably, the respiratory mask 12 is made of a silicone material.

To improve the breathing structure of the scuba 1, avoiding mixing of inhaled air with exhaled carbon dioxide gas, a first breathing tube assembly 20 and an exhalation check valve 30 are used in this embodiment.

The first breathing tube assembly 20 includes a first breathing tube 21 and an inhalation check valve 22 (also referred to as a forward check valve), such that the first breathing tube 21 is disposed on the outside of the outer mask 11, and a mounting opening is provided on the outer mask 11 to enable the first breathing tube 21 to be mounted with the inhalation check valve 22. Here, the first breathing tube 21 and the inhalation check valve 22 may be mounted in two ways: the first breathing tube 21 is connected and installed with the breathing mask 12 through the installation opening by the inspiration one-way valve 22 so as to communicate the breathing mask 12 with the external environment, the inspiration one-way valve 22 can be installed at any position of the first breathing tube 21, preferably, the inspiration one-way valve 22 is arranged at the bottom end of the first breathing tube 21 so that the first breathing tube 21 has the longest length, and has better flexibility and adaptability to the submergence depth in use. The other is that the inspiration one-way valve 22 is arranged in the first breathing tube 21, and the first breathing tube 21 passes through the mounting opening and is connected with the breathing mask 12. By using the inhalation check valve 22, the first breathing tube 21 is connected to the breathing chamber 121 during inhalation, and air can only flow into the breathing chamber 121 through the first breathing tube 21, thereby forming an air intake passage.

An exhalation check valve 30 (also referred to as a reverse check valve) is installed in connection with the outer cover 11 and the breathing cover 12 to communicate the breathing chamber 121 with the outside. When in expiration, the gas is exhaled to the outside through the expiration check valve 30, backflow of the gas is prevented, and the gas is directly exhaled through the expiration check valve 30, and the gas can be rapidly exhausted due to the fact that the exhalation channel is short, so that mixing of air and the exhaled gas is further avoided.

It can be seen that by using the first breathing tube assembly 20 and the exhalation check valve 30, respectively, an air intake passage is formed in which the first breathing tube 21 communicates with the breathing mask 12, and air can only enter; the exhalation flow path formed by the exhalation check valve 30 allows instantaneous, large volume, rapid evacuation of air. The breathing in the respiratory system is mechanically separated, and the mixing of gases in the respiratory mask 12 is effectively avoided.

In addition, a mounting bracket 15 can be arranged on the mask for mounting the shooting device, so that underwater shooting is facilitated.

According to the technical scheme, the mask 10, the first breathing tube assembly 20 and the expiration one-way valve 30 are adopted, on one hand, the first breathing tube 21 in the first breathing tube assembly 20 is connected with the breathing mask 12 of the mask 10 through the inspiration one-way valve 22, or the inspiration one-way valve 22 is arranged in the first breathing tube 21, the first breathing tube 21 is connected with the breathing mask 12, so that when in inspiration, the inspiration valve is conducted, and air flows into the breathing cavity 121 through the first breathing tube 21; on the other hand, the exhalation check valve 30 is attached to the outer cover 11 and the respiratory cover 12 of the mask 10 so that the exhalation check valve 30 is turned on during exhalation and the exhalation gas flows out to the outside through the exhalation check valve 30. An air suction one-way valve 22 is arranged through the first breathing tube 20, so that air can only enter; simultaneously, the carbon dioxide is exhaled through the exhalation check valve 30 and the multiple pipelines for instant and massive discharge, and the gas is smoothly discharged without water inflow.

The valve cover 221 and the valve body 222 are respectively arranged on the first breathing tube 21 and the breathing mask 12, and the valve cover 221 and the valve body 222 are connected through threads, so that the first breathing tube 21 and the breathing mask 12 are connected, the installation is convenient, and a good sealing effect is achieved. While facilitating maintenance and replacement of the suction check valve 22 during use. Of course, other mounting methods may be adopted, such as mounting the inhalation check valve 22 on the first breathing tube 21, and connecting the inhalation check valve 22 with the breathing mask 12; or the inhalation check valve 22 is mounted on the breathing mask 12 and then connected with the first breathing tube 21. It is easy to understand that the valve body 222 and the valve cover 221, and the inhalation check valve 22 and the first breathing tube 21 or the breathing mask 12 may be mounted by a plate type connection or a clamping connection, etc. besides the threaded connection.

Referring to fig. 3 and 4, the first breathing tube 21 includes a tube body 211 and a top cover 212 covering the top end of the tube body 211, the bottom end of the tube body 211 is connected with a valve cover 221, an air inlet 2111 for air to flow in is provided at the upper part of the tube body 211, and a water leakage preventing structure is provided in the tube body 211. Through the tube 211, air is caused to flow in through an air inlet 2111 on the tube 211, through the tubing, and to the breathing chamber 121. The pipe body 211 is internally provided with a water leakage preventing structure so as to seal the pipeline through the water leakage preventing structure when the air inlet 2111 is submerged in water, and prevent choking and water choking caused by blocking gas flowing in the pipeline. Through adopting top cap 212, make top cap 212 detachable lid locate body 211, be convenient for not only drip the remaining commercial volume water in the body 211, conveniently clean body 211 moreover, make body 211 keep clean, ensure human health.
