Description

Technical Field

[0001] The technical problem to be solved by this utility model is to overcome at least one of the shortcomings of the prior art and to provide a toilet water circuit distribution pipe. Background Technology

[0002] Modern toilets typically use a split-pipe system to divert water for different functions, such as personal hygiene or toilet brush ring operation. Within this system, a valve stem distributes water to each function. The valve stem is inserted into the split-pipe, but the pipe itself has holes for connecting different functions. During installation, the sealing ring on the split-pipe can be affected by the edge of these holes, causing it to curl or slip.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0024] The following will be combined with the appendix Figure 1 To be continued Figure 5 The technical solutions in the embodiments are described clearly and completely.

[0025] An embodiment of this utility model provides a toilet water circuit, which is installed in the toilet and used to supply water to the toilet tank or other water-using components. (See reference...) Figure 1 The toilet water system includes a water source pipe 3, a body cleaning water pipe 5, a brush ring water pipe 4, and a distribution pipe 1 connecting these three pipes. The distribution pipe 1 includes a distribution pipe body 11 and a distribution valve stem 2. The main body of the distribution pipe body 11 is cylindrical, with an inlet pipe 14, a first outlet pipe 15, and a second outlet pipe 16 extending radially from its outer periphery. The distribution pipe body 11 is integrally formed. The main body of the distribution pipe body 11 extends axially and has a water channel that runs through the main body and extends axially.

[0026] refer to Figure 2 and Figure 3 The water distribution channel includes a first end 12, a second end 13 along the axial direction, and a water distribution cavity 17 between the first end 12 and the second end 13. A water inlet hole 141 is formed between the water distribution cavity 17 and the inlet pipe 14, a first water outlet hole 151 is formed between the water distribution cavity 17 and the first outlet pipe 15, and a second water outlet hole 161 is formed between the water distribution cavity 17 and the second outlet pipe 16. The radial dimension of the second end 13 of the water distribution channel is smaller than the radial dimensions of the first end 12 and the water distribution cavity 17. The second end 13 and the water distribution cavity 17 are connected by a guide ramp 131. At least one annular sealing groove is respectively formed on the first end 12 and the second end 13.

[0027] refer to Figure 4 and Figure 5 The water distribution valve stem 2 includes a shaft, a water passage 24 disposed on the outer periphery of the shaft, and a sealing part 23. The outer periphery of the shaft includes a water channel forming part, which is formed with a diameter smaller than the inner peripheral wall of the water distribution cavity 17 to form the water passage 24 by being spaced apart from the inner peripheral wall of the water distribution cavity 17.

[0028] The water distribution valve stem 2 is rotatably supported on the water distribution pipe body 11 relative to the water distribution pipe body 11. The water distribution valve stem 2 includes a force receiving operation part 27, which is disposed on one side of the first end 12 and outside the water distribution pipe body 11. The shaft body is detachably connected to the force receiving operation part 27. In other embodiments, the force receiving operation part 27 and the shaft body may be integrally formed. The force receiving operation part 27 includes a plane intersecting the axial direction, thus enabling it to be pushed by an external force and rotate about the axis. In other embodiments, the force receiving operation part 27 may be connected to a drive source via a threaded connection, a pin connection, or other connection methods.

[0029] refer to Figure 3 , Figure 4 and Figure 5 The water distribution valve stem 2 has a first sealing part 21 and a second sealing part 22 at the ends of both sides of the water passage 24. The toilet water distribution pipe 1 also includes a first annular sealing component and a second annular sealing component. The outer periphery of the first sealing part 21 and the second sealing part 22 respectively includes at least one annular sealing groove, and the first annular sealing component and the second annular sealing component respectively include an O-ring seal disposed in the annular sealing groove.

[0030] By setting the radial dimension of the second annular sealing component to be smaller than that of the first annular sealing component, the first end 12, and the water distribution cavity 17, during the insertion of the second end 13 from the first end 12, the second annular sealing component will not contact the inner wall of the first end 12, the water inlet 141, the water outlet, and the water distribution cavity 17 with greater pressure, or it will not contact the inner wall of the first end 12, the water inlet 141, the water outlet, and the water distribution cavity 17. Therefore, the second annular sealing component will not roll over or slip off under greater pressure.

[0031] refer to Figure 3 , Figure 4 and Figure 5When the force receiving operation unit 27 is operated by an external force, the water distribution valve rod 2 rotates under the operating force. The water distribution valve rod 2 can be operated into a first posture and a second posture. The water passage 24 includes a radially extending blocking part 23. The blocking part 23 blocks the water inlet hole 141 in the first posture and disconnects the water inlet hole 141 in the second posture. The first water outlet hole 151 is connected to the toilet brush ring water passage, and the second water outlet hole 161 is connected to the human body cleaning water passage. The first posture and the second posture of the water distribution valve rod 2 are postures after rotating around the axis by an angle from the other posture, so that the blocking part 23 blocks the water inlet hole 141 and opens the water inlet hole 141. The radial dimension of the blocking part 23 is larger than the radial dimension of the water inlet hole 141 and fits the inner peripheral wall of the water distribution channel, thereby blocking the water inlet hole 141.

[0032] refer to Figure 4 and Figure 5 The force receiving operation unit 27 also includes a positioning ring 28 extending radially outward. The positioning ring 28 abuts against the end of the water distribution pipe body 11 to prevent the water distribution valve rod 2 from moving relative to the water distribution pipe body 11 toward the second end 13. The end of the water distribution valve rod 2 away from the force receiving operation unit 27 has an annular groove 25. The toilet water distribution pipe 1 also includes a positioning ring 26, which is engaged in the annular groove 25 to prevent the water distribution valve rod 2 from moving relative to the water distribution pipe body 11 toward the force receiving operation unit 27.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
