[0005] Furthermore, a first positioning tube is provided on the outer port of the air intake, and one end of the air guide tube is inserted into the first positioning tube.

[0006] Furthermore, the one-way exhaust valve includes a sealing sheet, the sealing sheet is provided with a connecting boss, the top of the connecting boss is provided with a positioning boss, the inner port of the air intake and the outer port of the air outlet are respectively provided with positioning plates, the positioning plates are provided with positioning holes, the connecting boss passes through the positioning holes, and the positioning boss is engaged with the positioning holes.

[0007] Furthermore, a second positioning tube is provided at the outer port of the air outlet, the one-way exhaust valve is located inside the second positioning tube, an air outlet pipe is connected to the second positioning tube, and one end of the air outlet pipe is fixedly connected to the float plate.

[0008] Compared with the prior art, this utility model has the following beneficial effects:

[0009] This invention uses a longer air tube to replace the traditional exhalation tube, allowing users to dive to deeper waters. The float plate ensures that the end of the air tube is always above the water surface. The guide valves on the mouthpiece's air inlet and outlet ensure the direction of air flow and prevent water from flowing back into the mouthpiece, thus ensuring normal breathing for the user underwater.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model discloses an underwater breathing apparatus, see reference. Figure 1The device includes a mouthpiece 1 made of silicone material, with independent air inlets 11 and outlets 12. One-way exhaust valves 13 are located at the inner port of the air inlet 11 and the outer port of the outlet 12. An air guide tube 2 is also included, with one end sealed to the outer port of the air inlet 11 and the other end equipped with a float 21 that always floats on the water surface. This end of the air guide tube 2 is higher than the float 21 to prevent water from entering. When the user inhales, the one-way exhaust valve 13 at the air inlet 11 opens, allowing air from the water surface to flow through the guide tube to the mouthpiece 1 for inhalation. When the user exhales, the one-way exhaust valve 13 at the outlet 12 opens, allowing the exhaled air to escape through the outlet 12, thus completing the inhalation-exhalation cycle. The air guide tube 2 can be 1-2 meters long to allow for breathing at deeper dives.

[0020] See Figure 2 The outer port of the air intake duct 11 is provided with a first positioning tube 14, and one end of the air guide tube 2 is inserted into the first positioning tube 14.

[0021] See Figure 3 , 4 In this embodiment, the one-way exhaust valve 13 includes a sealing sheet 131, a connecting boss 132 on the sealing sheet 131, and a positioning boss 133 at the top of the connecting boss 132. The sealing sheet 131, the connecting boss 132, and the positioning boss 133 are integrally molded from flexible materials such as silicone. Positioning plates 15 are respectively provided at the inner port of the air inlet 11 and the outer port of the air outlet 12. Several airflow outlets are provided around the periphery of the positioning plates 15. Positioning holes 151 are provided on the positioning plates 15. The connecting boss 132 passes through the positioning holes 151. The position of the one-way exhaust valve 13 is fixed by the engagement of the positioning boss 133 with the positioning holes 151. When the user breathes, the sealing sheet 131 at the corresponding position tilts up, and airflow flows through the airflow outlets around the positioning plates 15. After breathing, the sealing sheet 131 re-seals the corresponding port.

[0022] In other embodiments, a second positioning tube may be provided at the outer port of the air outlet 12. The second positioning tube is arranged side by side with the first positioning tube 14. The one-way exhaust valve 13 is located inside the second positioning tube. An air outlet pipe is connected to the second positioning tube. One end of the air outlet pipe is fixedly connected to the float 21. The port of the air outlet pipe is also located above the water surface, thereby avoiding the impact on the diving experience caused by air bubbles generated underwater.

[0023] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
