[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] To facilitate understanding of this embodiment, an underwater breathing apparatus disclosed in an embodiment of the utility model is first introduced in detail.

[0029] Example:

[0030] See also Figure 1 and Figure 2 The present application discloses an underwater breathing apparatus, comprising a mouthpiece 100, a connecting piece 200 and two gas cylinders 300. The mouthpiece 100 is mounted on the connecting piece 200. Two gas cylinders 300 are arranged opposite to each other on both sides of the connecting piece 200. The connecting piece 200 has an airway 201 communicating with the two gas cylinders 300. The gas cylinders 300 are arranged on both sides of the connecting piece 200 so that a snorkeler can maintain balance after biting the mouthpiece 100 in the water, which is convenient for the snorkeler to bite the mouthpiece 100 steadily and complete underwater activities. When snorkeling, the snorkeler bites the mouthpiece 100, and the oxygen in the gas cylinders 300 is supplied to the snorkeler through the airway 201, so as to assist the snorkeler in completing underwater activities. The apparatus has a reasonable structure and is convenient to carry, and can effectively improve the freedom of underwater activities of the snorkeler and ensure the safety of the snorkeler.

[0031] Specifically, the mouthpiece 100 is made of a thermoformed material to reduce the possibility of the mouthpiece 100 being broken. The connector 200 is a hexagonal prism, and two opposite sides of the connector 200 respectively extend with connecting parts in the direction of the gas cylinder 300, and the connecting parts are threadedly connected to the connector interface 403 of the valve 400 to achieve a fixed connection between the connector 200 and the valve 400. The gas cylinder 300 is a miniature oxygen cylinder, which is easy to carry.

[0032] As a preferred embodiment of the present application, the present application also includes a valve 400, which is arranged between the connector 200 and the gas cylinder 300. The valve 400 has a knob switch 401, a gas cylinder interface 402 and a connector interface 403. The gas cylinder interface 402 is threadedly connected to the gas cylinder 300, and the connector interface 403 is threadedly connected to the connector 200. Through the valve 400, the snorkeler unscrews the valve 400, and the oxygen in the gas cylinder 400 can supply the snorkeler with gas to help the snorkeler complete underwater activities. Of course, the snorkeler can freely adjust according to the time and needs of snorkeling to maximize the use of the gas cylinder 400.

[0033] As a preferred method of the present application, the gas cylinder interface 402 is connected to the gas cylinder 300 through a filter tube 404. During the input process, the oxygen in the gas cylinder 300 is filtered for impurities by the filter tube 404 and then enters the airway 201 for use by snorkelers, thereby effectively ensuring the purity of the oxygen and further ensuring the safety of the snorkelers' oxygen use.

[0034] As a preferred embodiment of the present application, a first sealing ring 405 is provided at the connection between the gas cylinder interface 402 and the gas storage cylinder 300, and a second sealing ring 406 is provided at the connection between the connector interface 403 and the valve 400. Through the design of the first sealing ring 405 and the second sealing ring 406, the sealing between the valve 400 and the connector 200 and the gas storage cylinder 300 is further improved.

[0035] As a preferred embodiment of the present application, a plurality of strip-shaped protrusions 4011 are evenly distributed on the outer circumferential surface of the knob switch 401, so as to increase the friction between the snorkeler and the knob switch 401 when the snorkeler rotates the knob switch 401, thereby preventing the snorkeler from being unable to rotate the knob switch 401 underwater due to the smooth surface of the knob switch 401, thereby improving the safety of use.

[0036] Specifically, if Figure 3 As shown, the airway 201 includes a circular airway 2011 and two straight airways 2012 connected to the circular airway 2011 , wherein the circular airway 2011 is connected to the channel of the mouthpiece 100 , and the two straight airways 2012 are respectively connected to the corresponding filter tubes 404 .

[0037] Specifically, an annular rib 101 extends from one end of the mouthpiece 100 toward the connecting member. The annular rib 101 is embedded in the circular airway 2011 of the connecting member 200 to improve the connection stability between the mouthpiece 100 and the connecting member 200 .

[0038] In summary, the present application solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable structure, easy to carry, and strong practicality.
