EXAMPLE

Referring to Figures 1 and 2, a preferred implementation of the toilet flushing device according to the present invention is shown to be installed in the toilet flush toilet (10). The toilet flush toilet 10 includes a toilet flush toilet having a water tank, a rim flush pipe 54 and a neck portion 55. The feed pipe 21 has a lower end extending into the water supply tank interior 50 and connected to a water source having a constant atmospheric pressure thereon and an upper end provided with the conventional ball-cock valve 22. The rod 25 connects to the ball-cock valve 22 as a main float 252. The feed tank 50 provides a discharge outlet 56. The flapper valve 52 normally shuts off the discharge outlet 56 and is hinged at one end of the feed tank 50. The other end of the flapper valve 52 is coupled to the actuating arm of the conventional flush arm and is mounted to the outside of the shank 50 by means of a chain or cable 58. The flush handle 51 is operated to lift the flapper valve to supply water into the tank 50 with flow through the discharge outlet 56. The discharge pipe 57 directs water flow through the discharge outlet 56 to the neck 55 of the toilet flush 53 in an unprecedented manner. When the water level in the tank 50 is lowered, the main float 252 will be lowered, thereby opening the ball-cock valve 22. Water from the water supply pipe 21 is led to the diverter valve device 30 of the toilet flushing device, and to the water supply tank 50 and the water supply pipe 21 to refill the tank 50 until it reaches the normal water level. Fluidly transfer, and then the main float 252 shuts off the ball-cock valve 22.

1, 3, 4, 5 and 6, the diverter valve device 30 of the present invention comprises a hollow valve housing 31, a transverse inlet pipe 21b, and draws water from the water supply pipe 21. The water supply is supplied to the rim flush pipe 54 to which the water supply line 40 is connected. The valve housing 31 is actually cylindrical and has transverse bulkheads between the upper and lower walls 3101 and 3102, the upper and lower walls 3101 and 3102, and the upper and lower chambers 31a and 31b are partitions 3103. Separated by). The partition 3103 has an opening 311 and a first valve set 3111 confining the opening 311. Inlet pipe 21b and supply line 40 are connected to upper and lower chambers 31a and 31b, respectively. The valve housing 31 has a delivery device for connecting the upper chamber 31a and the water supply tank 50 to each other, as described below.

Referring to FIGS. 3 and 5, the diverter valve device 30 has a valve rod having top and bottom ends 321, 322 and a passageway, the passageway extending longitudinally through the valve rod and supplied as a delivery device. Alternatively, the delivery device may be apertured in the top wall of the valve housing 31 when the valve rod 32 is formed as a solid rod. The upper end 321 of the valve rod 32 extends into the upper chamber interior 31a and is provided to the valve member 33. The bottom 322 extends out of the bottom extension tube 312 of the valve housing 31. The valve rod 32 penetrates through the opening 311 of the partition 3103 which is not sealed and opens through the extension tube 312 to the bottom wall 3102. The threaded portion 321a is provided near the lower end 322 of the valve rod 32. The nut 313 engages the threaded portion 321a. The upper wall 3101 of the valve housing 31 has a second valve set 3104 formed therein. The valve rod 32 has a spring member 34 sleeveed around the valve member 33 and the bottom wall 3102. The spring member 34 moves above the valve rod 32 to move the valve member 33 away from the first valve set 3111 and install the valve member 33 against the second valve set 3104. Usually it is eccentric.

Referring to FIGS. 3, 4, and 5, the diverter valve device 30 has a float member 35 with a float body 351 sleeved over the feed pipe 21, and extends from the float body 351. Which has a transverse plate 352. The extension tube 312 and the valve rod 32 slide likewise through the transverse plate 352. However, the float member 35 is directly sleeved on the extension tube 312 and the valve rod 32 without using the extension plate 351 described above.

Referring to FIGS. 2 and 7, when the tank 50 is initially full, the float member 35 flows along the water passage and exerts no attraction to the cable 58. The valve member 33 abuts against the second valve set 3104 due to the upward spring force of the spring member 34. When the flush handle 51 is actuated, the flapper valve 52 flows into the discharge outlet 56 and the neck 55 of the toilet flush 53 to fill the water in the tank 50. It is raised. When the water level in the tank 50 falls, the main float 252 and the float member 35 are lowered, thereby opening the ball-cock valve 22. High pressure water from the water supply pipe 21 enters the diverter valve device 30 and is led to the supply line 40. The high pressure water enters the rim flush tube 54 in this way, thereby efficiently flushing the internal water of the toilet flush toilet.

Referring to FIG. 8, when the water level in the tank 50 gradually decreases continuously, the elongate plate 352 of the float member 35 moves downwards and eventually to the nut 313. The valve is engaged and moves downward against the spring force of the spring member 34 to apply the valve member 33 by installation on the first set of valves 3111, as well described in FIG. 9. Pull the rod 32. Water from the inlet pipe 21b then flows into the through passage 3210 of the valve rod 32 to refill the tank 50. Preferably, a gap (not shown) is formed between the valve member 33 and the first valve set 3111. As the valve member 33 is installed on the first valve set 3111, a small amount of water from the inlet pipe 21b passes through the gap to refill the toilet flush 53 and the supply line 40. A large amount of water flows into the tank 50 through the valve rod 32 as it enters. The length of time while the valve rod 32 is pulled by the float member 35 can be applied by the rotation of the nut 313 over the threaded portion 321a, whereby the extension plate of the float member 35 ( The distance between 352 and the nut 313 varies. More water flows into the supply line 40 as the nut 313 moves upwards, at a high position relative to the lower end 322 of the valve rod 32. Thus, a small amount of water flows through the supply line 40 as the nut 313 moves downward relative to the bottom 322 of the valve rod 32.

Referring to FIG. 10, when the water level rises in the tank 50, the main float 252 and the float member 35 gradually move upwards. In this step, the float member 35 is not connected to the nut 313, and the pullout member 33 is the first valve set 3111 due to the high pressure water applying pressure to the valve member 33. Is mounted on top. The valve rod 32 causes the valve member 33 to cause the second set of valves due to the restored force of the spring member 34 when the main float 252 shuts off the cock-ball valve 22. Move upwards to enable contact with 3104. This prevents water flow from the water supply pipe 21 inside the diverter valve device 30.

The high pressure water flows out of the water supply pipe 21 through the valve rod 32 when the tank 50 is refilled with water, thereby forming dirty substances in the upper end portion 321 and the through passage 3210. Can be avoided.

When the present invention is described in the context of the most practical and desirable practice, it is intended that the present invention is intended to be applied to a variety of installations that are within the scope and intent of the equivalent of the broadest description without limiting the published practice. Will understand that.

As described above, the toilet flushing device according to the present invention has a diverter valve device for guiding water from the water supply pipe of the toilet flush toilet to the rim flush tube of the flush toilet, and cleans the delivery device when high pressure water flows from the inlet pipe. It is possible to thereby prevent the formation of contaminants in the delivery device.
