The valve disc includes a first elastic opening and closing portion and a second elastic opening and closing portion. The first and second elastic opening and closing portions are located within the water passage chamber. When the valve disc is pushed by the endoscope to the endoscope-sealed engagement state, the first and second elastic opening and closing portions are pushed against each other by the endoscope to form a passage area for the endoscope to pass through, and the valve disc is in a liquid-sealed engagement with the endoscope. When the valve disc is in the normally closed state, the first and second elastic opening and closing portions abut against each other under their respective elastic forces to form a liquid-sealed engagement.

[0006] The valve disc further includes a first side-mounted connecting portion and a second side-mounted connecting portion; the first side-mounted connecting portion is disposed between one end of the first elastic opening and closing portion and the second elastic opening and closing portion; the second side-mounted connecting portion is disposed between the other end of the first elastic opening and closing portion and the second elastic opening and closing portion.

[0007] The valve disc also includes a support plate, and the first elastic opening and closing part and the second elastic opening and closing part are disposed on the support plate. The support plate is provided with a guide hole for the endoscope to pass through.

[0008] The valve seat is provided with an embedding groove, and the edge of the support plate is embedded in the embedding groove.

[0009] The support plate includes a main body and a protrusion; the protrusion is disposed on the main body, and the first elastic opening and closing part and the second elastic opening and closing part are disposed on the protrusion; the embedding groove includes a main groove and a positioning groove; the positioning groove is connected to the main groove; the protrusion is embedded in the positioning groove, and the main body is embedded in the main groove.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-5 As shown, a one-way valve of a steam therapy device includes a valve seat 10 and a valve disc 20; the valve seat 10 is provided with a water passage chamber 11, and the valve disc 20 is normally closed and adapted to be pushed to an endoscope-sealed engagement state by an endoscope; the valve disc 20 includes a first elastic opening and closing part 21 and a second elastic opening and closing part 22; the first elastic opening and closing part 21 and the second elastic opening and closing part 22 are located within the water passage chamber 11; when the valve disc 20 is pushed to the endoscope-sealed engagement state by the endoscope, the first elastic opening and closing part 21 and the second elastic opening and closing part 22 are pushed by the endoscope to form a passage section between the first elastic opening and closing part 21 and the second elastic opening and closing part 22 for the endoscope to pass through, and the valve disc 20 is in a liquid-sealed engagement with the endoscope; when the valve disc 20 is in the normally closed state, the first elastic opening and closing part 21 and the second elastic opening and closing part 22 are pressed against each other under the action of their respective elastic forces to form a liquid-sealed engagement (e.g., Figure 3 (As shown).

[0019] When the endoscope is in use, as it is moved toward the one-way valve, the end of the endoscope pushes against the first elastic opening and closing part 21 and the second elastic opening and closing part 22, causing the first elastic opening and closing part 21 and the second elastic opening and closing part 22 to undergo elastic deformation and move away from each other. This creates a passageway between the first elastic opening and closing part 21 and the second elastic opening and closing part 22 for the endoscope to pass through, facilitating the movement of the endoscope through the one-way valve. At the same time, the valve disc 20 forms a liquid seal with the outer wall of the endoscope to prevent liquid leakage. When the one-way valve is in its normal state (e.g., the normal state after the endoscope is removed), the first elastic opening and closing part 21 and the second elastic opening and closing part 22 return to their original positions under their respective elastic forces to form a liquid seal, so that the valve disc 20 is in a normally closed state, blocking the passage of water and improving the sealing effect. Therefore, the one-way valve of the steam therapy device provided by this utility model has a normally closed state and an endoscope-sealed state for the valve disc 20, and the valve disc 20 uses the first elastic opening and closing part 21 and the second elastic opening and closing part 22. When the valve disc 20 is in the normally closed state, the first elastic opening and closing part 21 and the second elastic opening and closing part 22 come into contact with each other under their respective elastic forces to form a liquid seal, thereby achieving good sealing performance in the normal state of the one-way valve. When the valve disc 20 is pushed to the endoscope-sealed engagement state by the endoscope, the first elastic opening and closing part 21 and the second elastic opening and closing part 22 are pushed by the endoscope to form a passage zone for the endoscope to pass through between the first elastic opening and closing part 21 and the second elastic opening and closing part 22. At the same time, the valve disc 20 and the endoscope are in a fluid-sealed engagement, which not only improves the sealing performance under normal conditions, but also facilitates the insertion of the endoscope when it is used in conjunction with the endoscope, and improves the good sealing performance during use, thereby improving the reliability of use.

[0020] The valve disc 20 further includes a first side-mounted connecting portion 24 and a second side-mounted connecting portion 25. The first side-mounted connecting portion 24 is disposed between one end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22; the second side-mounted connecting portion 25 is disposed between the other end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22. By disposing the first side-mounted connecting portion 24 between one end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22, and disposing the second side-mounted connecting portion 25 between the other end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22, the structural strength and integrity of the valve disc 20 are enhanced, preventing the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22 from becoming misaligned or falling off during repeated opening and closing, ensuring its sealing reliability during long-term use, and improving the durability of the product.

[0021] The valve disc 20 also includes a support plate 26. The first elastic opening and closing part 21 and the second elastic opening and closing part 22 are disposed on the support plate 26, and the support plate 26 is provided with a guide hole 29 for the endoscope to pass through. When the endoscope is moved into the one-way valve, the end of the endoscope first passes through the guide hole 29, then pushes open the first elastic opening and closing part 21 and the second elastic opening and closing part 22, and then passes through the passage between the first elastic opening and closing part 21 and the second elastic opening and closing part 22. By adopting the above structure, the assembly process of the valve disc 20 can be simplified. At the same time, the guide hole 29 plays the role of guiding the endoscope, ensuring that the endoscope can push the first elastic opening and closing part 21 and the second elastic opening and closing part 22 along the predetermined path, avoiding jamming or sealing failure caused by deflection, and improving the smoothness and safety of use.

[0022] The valve seat 10 is provided with an embedding groove 40, and the edge of the support plate 26 is embedded in the embedding groove 40. By adopting the above structure, the installation of the valve disc 20 can be facilitated, and the stability of the installation between the valve disc 20 and the valve seat 10 can be improved.

[0023] The support plate 26 includes a main body 27 and a protrusion 28. The protrusion 28 is disposed on the main body 27, and the first elastic opening / closing part 21 and the second elastic opening / closing part 22 are disposed on the protrusion 28. The embedding groove 40 includes a main groove 41 and a positioning groove 42. The positioning groove 42 communicates with the main groove 41. The protrusion 28 is embedded in the positioning groove 42, and the main body 27 is embedded in the main groove 41. Specifically, the diameter of the main body 27 is larger than the diameter of the protrusion 28. By embedding the protrusion 28 in the positioning groove 42 and the main body 27 in the main groove 41, the accuracy of the valve disc 20 installation and positioning can be improved, and the stability of the valve disc 20 fixation can be improved.

[0024] The valve disc 20 is made of silicone or rubber. Specifically, the valve disc 20 is integrally molded. By utilizing the elasticity and flexibility of silicone or rubber, the first elastic opening and closing part 21 and the second elastic opening and closing part 22 can be easily pushed open to form a passage area when pushed by the endoscope. After the endoscope is removed, the valve disc 20 can quickly and tightly return to its original shape to achieve self-sealing. By adopting the above structure, a good sealing effect can be achieved, and the manufacturing process is relatively simple, requiring no assembly and saving assembly steps and costs.

[0025] The valve seat 10 is provided with an inlet hole 13, a return hole 14, and an outlet hole 15; the inlet hole 13, the return hole 14, and the outlet hole 15 are respectively connected to the water passage chamber 11. Physiological saline can flow into the water passage chamber 11 through the inlet hole 13 and flow to the endoscope through the cavity through the outlet hole 15, while excess physiological saline can be discharged through the return hole 14.

[0026] The valve seat 10 includes a first valve housing 50, a second valve housing 60, and a valve cover 12; the second valve housing 60 is fixedly connected to the first valve housing 50, and the second valve housing 60 and the first valve housing 50 form a water passage cavity 11; the valve cover 12 is fixed on the second valve housing 60. By using a combination of the first valve housing 50, the second valve housing 60, and the valve cover 12 for the valve seat 10, the manufacturing difficulty and cost can be reduced, and the formation of the water passage cavity 11 can be facilitated.

[0027] The valve disc 20 is fixed to the first valve housing 50. An inlet connecting journal 51 is provided on one side of the first valve housing 50, and a return connecting journal 52 is provided on the other side. The inlet hole 13 is located on the inlet connecting journal 51, and the return hole 14 is located on the return connecting journal 52. In use, the inlet pipe can be connected to the inlet connecting journal 51, and the return pipe can be connected to the return connecting journal 52, so that physiological saline can be introduced into the inlet hole 13 through the inlet pipe, while excess physiological saline can be discharged from the return pipe through the return hole 14.

[0028] The water outlet 15 extends from the valve cover 12 to the second valve housing 60. Preferably, the second valve housing 60 has a valve neck 63 at the end away from the first valve housing 50, and the valve cover 12 is fitted onto the valve neck 63. By adopting the above structure, the installation between the valve cover 12 and the second valve housing 60 can be facilitated.

[0029] The second valve housing 60 includes a main housing 61 and a protruding wall 62. The protruding wall 62 is arranged around the periphery of the main housing 61. The first valve housing 50 is fitted onto the second valve housing 60. The first valve housing 50 has an internal groove 53. The protruding wall 62 is embedded in the internal groove 53 and abuts against the end wall of the internal groove 53 away from the valve cover 12. The end of the main housing 61 away from the valve cover 12 protrudes relative to the protruding wall 62 in a direction away from the valve cover 12. By adopting the above structure, the accuracy of the installation and positioning between the second valve housing 60 and the first valve housing 50 can be improved.
