[0002] With the continuous advancement of technology, people's demands for quality of life are increasing, and massage bathtubs are becoming increasingly popular and used more frequently. Currently, common one-way valves on the market are generally made of PVC or ABS, which have relatively low temperature resistance. They often malfunction due to deformation of critical parts (such as the sealing ring), causing damage to the air pump due to water backflow. To address this, the inventor has proposed a transparent, high-temperature resistant one-way valve. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0027] In related technologies, with the continuous advancement of science and technology, people's requirements for quality of life are getting higher and higher, and massage bathtubs are gradually becoming popular and being used more and more frequently. Currently, the materials commonly used in the market for one-way valves are generally PVC or ABS, which have relatively low temperature resistance. They often fail due to deformation of key parts of the product (such as the sealing ring), causing the air pump to be damaged by water backflow.

[0028] This embodiment provides a transparent, high-temperature resistant one-way valve, which can reduce the probability of water backflow caused by deformation of the sealing ring.

[0029] Please see Figures 1-2In this embodiment, a transparent high-temperature resistant one-way valve includes an upper housing 10, a lower housing 20, and a guide shaft 30. The upper housing 10 is provided with a mounting plate 11 inside. The lower housing 20 is connected and communicates with the upper housing 10, and the lower housing 20 is provided with an air inlet 21 corresponding to the mounting plate 11 inside. The guide shaft 30 is fixedly connected to the mounting plate 11, and an upper cover 31 is sleeved on the guide shaft 30. A lower cover 32 is fixedly connected below the upper cover 31. A sealing ring 33 is pressed between the lower cover 32 and the upper cover 31. The sealing ring 33 abuts against the periphery of the air inlet 21. A spring 34 is compressed between the upper cover 31 and the mounting plate 11.

[0030] By using the technical solution of this embodiment, the sealing ring 33 is pressed between the upper cover 31 and the lower cover 32, which can ensure the overall flatness of the sealing ring 33 and reduce the probability of water backflow caused by the deformation of the sealing ring 33.

[0031] In this embodiment, the upper housing 10 is constructed as a cylindrical tube. The upper housing 10 is made of high-temperature resistant transparent PC material. A circular mounting plate 11 is provided inside the upper housing 10. The mounting plate 11 is coaxially arranged with the upper housing 10. Multiple connecting rods 12 are fixedly connected between the outer periphery of the mounting plate 11 and the inner wall of the upper housing 10. The multiple connecting rods 12 are evenly distributed along the circumference of the mounting plate 11. The gap between the mounting plate 11 and the upper housing 10 is used for airflow.

[0032] In this embodiment, the lower housing 20 is constructed as a cylindrical tube and is made of high-temperature resistant transparent PC material. A circular air inlet 21 is provided inside the lower housing 20. The air inlet 21 is coaxially arranged with the lower housing 20. The lower housing 20 is connected to the upper housing 10 and forms a fixed connection. The two can be fixed by adhesive bonding. After the two are connected, the air inlet 21 is coaxially arranged with the mounting plate 11, and the space between the air inlet 21 and the mounting plate 11 is used to install the guide shaft 30, the upper cover 31, the lower cover 32, the sealing ring 33, and the spring 34.

[0033] In this embodiment, the guide shaft 30 is constructed as a smooth cylindrical shape. The guide shaft 30 is made of stainless steel and is fixedly connected to the axis of the mounting plate 11. The guide shaft 30 extends toward the side where the air inlet 21 is located. A sleeve 35 is provided at the axis of the upper cover 31. The sleeve 35 is slidably sleeved on the outside of the guide shaft 30. A positioning ring 36 is provided on the top surface of the upper cover 31 and is engaged with the inside of the spring 34. The spring 34 is made of stainless steel. The positioning ring 36, the sleeve 35, and the upper cover 31 are coaxially arranged and are integrally formed. The lower cover 32 is screwed on the bottom of the upper cover 31. After the upper cover 31 and the lower cover 32 are connected, the space enclosed by the upper cover 31 and the lower cover 32 is closed. The lower end of the guide shaft 30 extends into the space. The sealing ring 33 is pressed between the upper cover 31 and the lower cover 32, and the outer diameter of the sealing ring 33 is larger than the diameter of the air inlet 21.

[0034] It should be noted that the upper cover 31 and the lower cover 32 are arranged coaxially and are both made of high-temperature resistant transparent PC material. The sealing ring 33 is fitted over the lower cover 32 and pressed between the upper cover 31 and the lower cover 32, which enhances the overall flatness of the sealing ring 33.

[0035] When in use, first install the one-way valve onto the air pump pipeline. When the air pump is working, under the action of air pressure, the upper cover 31, the lower cover 32 and the sealing ring 33 move upward along the guide shaft 30, so that the air inlet 21 is in the open state, and the airflow flows through the air inlet 21 to the upper housing 10. When the air pump stops working, under the action of the spring 34, the sealing ring 33 closes the air inlet 21, which can prevent water from flowing back and damaging the air pump.

[0036] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
