[0012] The present invention will now be described in further detail with reference to the accompanying drawings.
[0013] The present invention will be described in detail with reference to the accompanying drawings.
[0014] In a specific implementation, this utility model provides a water recycling device for a washbasin, including a drain 18 in the washbasin 1 and a water-saving three-way valve 2 connected by a connecting cap 19. A water recycling outlet pipe 4 is connected to the side outlet of the water-saving three-way valve 2, and a water storage device is provided below the outlet end of the water recycling outlet pipe. A water-free outlet pipe 3 is connected to the bottom outlet of the water-saving three-way valve 2, and the outlet end of the water-free outlet pipe is connected to a floor drain or sewage pipeline.
[0015] The water-saving three-way valve 2 includes a valve housing 5, an upper valve cover 6, a lower valve cover 7, a connecting screw 8, and a valve stem 9. The connecting screw 8 is used to fix the upper valve cover 6 and the lower valve cover 7. The bottom end of the connecting screw 8 extends out of the lower valve cover 7, and a fixing nut 15 is provided on the extended end. The valve stem 9 is located between the upper valve cover 6 and the lower valve cover 7. The top of the valve housing 5 is provided with a water inlet 10, the bottom end is provided with a first water outlet 11, and the side is provided with a second water outlet 12. One end of the valve housing 5 is provided with a detachable valve cover 13, and a valve stem outlet 14 is provided on the valve cover 13. One end of the valve stem 9 extends out of the valve cover outlet 14. A connecting ball head 16 is provided on the valve stem 9, and ball seats 17 adapted to the connecting ball head 16 are provided on the upper valve cover 6 and the lower valve cover 7. Below the washbasin 1, a drain assembly 18 and a connecting cap 19 are provided. The internal thread of the connecting cap 19 is connected to the external thread of the drain assembly 18, and its bottom end is used to connect to the water inlet 10. A control panel 20 is also included. A connecting flexible shaft 21 is provided between the control panel 20 and the valve stem 9. The front side of the control panel 21 is provided with a toggle lever 22, a water-use position 23, and a water-free position 24. The included angle between the water-use position 23 and the water-free position 24 is 90°.
[0016] As a further explanation of this utility model, the water storage device can be a water storage tank or other water storage container.
[0017] The specific implementation of this utility model is as follows:
[0018] When you start using it, if you think that the washbasin 1 has been used and is no longer usable, adjust the lever 22 on the control panel 20. Move the lever 22 to the no-water position 24. At the same time, the lever 22 drives the valve stem 9 to rotate through the connecting flexible shaft 21. The valve stem 9 makes the upper valve cover 6 fit with the second water outlet 12. The water in the washbasin 1 flows out from the first water outlet 11 and is discharged into the sewer through the no-water outlet pipe 3.
[0019] Assuming the used water in the washbasin 1 can be reused, the lever 22 on the control panel 20 is adjusted. When the lever 22 is moved to the water-use position 23, it simultaneously drives the connecting flexible shaft 21, causing the valve stem 9 to rotate. The valve stem 9 then brings the lower valve cover 7 into contact with the first water outlet 11, allowing water from the washbasin 1 to flow out from the second water outlet 12 and through the reuse water outlet pipe 4 into the water storage device. The water storage device can be a water tank or other water storage container. This allows used water to be stored in the water storage device, which can then be used for mopping or flushing the toilet, meeting water needs, saving water costs, and demonstrating strong practicality.
[0020] This utility model employs the aforementioned structure, placing the connecting ball head 16 on the valve stem 9 into the ball seat 17 on the upper valve cover 6 and lower valve cover 7, and fixing them together using the connecting screw 8 and fixing nut 15. Because the connecting ball head 16 and the ball seat 17 have an arc-shaped contact surface, they are movably connected, allowing the connecting ball head 16 to rotate inside the ball seat 17. This structure enables the upper and lower valve cover planes to seal against the planes of the water-saving three-way valve 2's outlet 11 and outlet 12. Rotating the valve stem 9 drives the upper and lower valve covers to rotate from 0 to 90 degrees.
[0021] The aforementioned water-saving three-way valve 2 can be controlled manually or electrically.
[0022] By adopting the above technical solution, water in the washbasin 1 can be effectively stored or discharged through the sewer, thus saving water costs.
[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
