[0028] It should also be understood that the terms used in this specification of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0029] See also Figure 1-Figure 5 The present invention provides a safe and leak-proof duckbill valve device. The safe and leak-proof duckbill valve device can effectively limit the depth of the water pipe 20 entering the duckbill valve 10, effectively preventing the water pipe 20 from stretching the pressure relief port 13 of the duckbill valve 10, thereby effectively preventing water leakage. To achieve the above technical objectives, the safe and leak-proof duckbill valve device includes a duckbill valve 10 and a water pipe 20. The specific structure is described as follows:

[0030] The duckbill valve 10 includes a mounting opening 11, the inner wall of which is provided with a raised stop 12. The stop 12 protrudes inward along the inner wall. The stop 12 can be arranged around the mounting opening 11 to better limit the position of the water pipe 20.

[0031] The water pipe 20 is inserted into the installation opening 11 and is located on one side of the limiting platform 12. Specifically, the water pipe 20 can be inserted into the limiting platform 12 to abut against the limiting platform 12. The limiting platform 12 limits the depth of the water pipe 20 entering the installation opening 11.

[0032] When the water pipe 20 is inserted into the limit platform 12 and abuts against it, the limit platform 12 restricts the water pipe 20 from continuing to move into the insertion port, which can effectively prevent the water pipe 20 from expanding the pressure relief port 13 of the duckbill valve 10, thereby effectively avoiding water leakage.

[0033] In the technical solution of the embodiment of the present utility model, a safe and leak-proof duckbill valve device includes a duckbill valve 10 and a water pipe 20. The duckbill valve 10 includes a mounting port 11, and the inner wall of the mounting port 11 is provided with a raised limit platform 12. The water pipe 20 is inserted into the mounting port 11 and is located on one side of the limit platform 12. When the water pipe 20 is inserted into the limit platform 12 and is against the limit platform 12, the limit platform 12 restricts the water pipe 20 from continuing to move into the insertion port, which can effectively prevent the water pipe 20 from expanding the pressure relief port 13 of the duckbill valve 10, thereby effectively preventing water leakage.

[0034] Furthermore, in some embodiments, such as this embodiment, the height of the limiting platform 12 is greater than the wall thickness of the water pipe 20. The height of the limiting platform 12 is greater than the wall thickness of the water pipe 20, so that the movement of the water pipe 20 can be better limited.

[0035] In the embodiment of the present invention, the height of the limiting platform 12 is 0.5-5 mm. For example, the height of the limiting platform 12 can be 0.5 mm, 1.5 mm, 2 mm, 3 mm, 4.5 mm or 5 mm.

[0036] Furthermore, the limiting platform 12 is integrally formed with the inner wall of the mounting opening 11. The design of integrally forming the limiting platform 12 with the inner wall of the mounting opening 11 ensures the reliability of the connection between the limiting platform 12 and the inner wall of the mounting opening 11 and reduces the manufacturing cost.

[0037] Furthermore, the safety and leak-proof duckbill valve device also includes a clamp 30. A clamp groove 21 is provided on the outside of the water pipe 20. When the water pipe 20 is inserted into the installation opening 11, the clamp groove 21 is located within the installation opening 11. The clamp 30 is tightened on the duckbill valve 10 at a position corresponding to the clamp groove 21. By tightening the clamp 30 on the duckbill valve 10 at a position corresponding to the clamp groove 21, the duckbill valve 10 and the water pipe 20 are tightly fixed together, effectively preventing the duckbill valve 10 from falling off the water pipe 20.

[0038] Furthermore, the duckbill valve 10 includes a pressure relief port 13, and a clearance of the pressure relief port 13 is 0.05-0.3 mm. For example, the clearance of the pressure relief port 13 can be 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, or 0.3 mm.

[0039] The wall thickness of the pressure relief opening 13 is 0.5 mm to 3 mm. For example, the wall thickness of the pressure relief opening 13 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm.

[0040] In the embodiment of the present invention, the pressure relief pressure is adjusted by adjusting the gap and wall thickness of the pressure relief port 13 of the duckbill valve 10 .

[0041] Furthermore, the safety and leak-proof duckbill valve device further includes a joint 40, which is fixedly connected to the water pipe 20. For example, the joint 40 is welded to the water pipe 20. The joint 40 is used to be threadedly connected to the water tank 50 of the water heater.

[0042] Furthermore, the duckbill valve 10 is made of a soft plastic material, such as rubber.

[0043] The present invention provides a water heater, comprising the safety and water leakage-proof duckbill valve device provided in any of the above embodiments. Specifically, the safety and water leakage-proof duckbill valve device is provided on the water tank 50 of the water heater.
