Detailed Description

Fig. 1 shows the automatic water cut-off device for toilet cistern leakage of the present invention, which comprises a control floating ball 1, a control floating ball pull rope 2, an installation pillar 3, a water flow delay measuring cylinder 4, a buoyancy ball 10, a buoyancy ball pull rope 11 and a water cut-off control lever 12. The water cut-off control lever 12 is supported by a mounting pillar 3, one end of the water cut-off control lever 12 is connected with the buoyancy ball 10, the other end is connected with the control floating ball 1, and the water cut-off control lever and the water flow delay measuring cylinder 4 form a water cut-off device which is integrally placed in a toilet water tank.

When the toilet water tank enters water through the water feeding pipe 15, along with the gradual rise of the water surface, at the moment, because the lower part of the water flow delay measuring cylinder 4 is provided with the overflow window 21, the water level of the water flow delay measuring cylinder 4 is kept consistent with the water surface height in the toilet water tank, the density of the control floating ball 1 is smaller than that of the toilet water tank water, and the control floating ball rises synchronously along with the water surface, and when the water surface in the toilet water tank rises to the specified height, the water feeding valve 14 closes water feeding under the action of the regulating valve lever 13 and the buoyancy ball 10 mechanism.

When the toilet needs to be flushed after use, the sealing valve pull rope 8 is pulled to discharge water, if the sealing valve 7 of the flushing port works normally, namely the flushing port 6 is closed after water discharge, at the moment, because the overflow window 21 at the lower part of the water flow delay measuring cylinder 4 is smaller, the liquid level in the water flow delay measuring cylinder 4 is higher than the liquid level in the toilet water tank, and the floating ball pull rope 2 is controlled to be in a loose state. The liquid level in the toilet tank gradually rises to be balanced with the water level in the water flow delay measuring cylinder 4, and the liquid level is synchronously raised to the upper water valve 14 to close water inlet, so that the flushing and discharging circulation of the toilet tank is completed.

If the sealing valve 7 of the flushing port fails to close in time after the water is discharged by pulling the sealing valve pull rope 8, namely the flushing port 6 leaks, the height of the liquid level inside the toilet tank depends on the water leakage and the water inlet flow, the water leakage makes the rising speed of the liquid level inside the toilet tank slower than the normal speed of the sealing valve 7 of the flushing port, when the water leakage flow is larger than the water inlet flow, the liquid level inside the measuring cylinder 4 is maintained at the lowest position, the liquid level inside the water delay measuring cylinder 4 is gradually reduced, when the water leakage flow is reduced to control the tightening of the float pull rope 2, the water-break control lever 12 is pulled to rotate, the buoyancy ball 10 is caused to rise, the water feeding valve 14 is closed through the action of the adjusting valve lever 13, and the purposes of.

The weight and the volume of the control floating ball 1 are optimally designed, so that the water-cut-off control lever 12 can be pulled to rotate when the water tank of the toilet leaks water, and the water-cut-off of the water-feeding valve 14 is realized. Meanwhile, when the toilet water tank is in a normal working state, the lowest point of the buoyancy ball is lower than the upper edge of the water flow delay measuring cylinder when the water feeding valve is cut off, and the floating ball 1 is ensured to be controlled to be always inside the water flow delay measuring cylinder 4.

Fig. 2 is a schematic view of the water flow delay measuring cylinder of the present invention, which is only illustrated by a cylindrical shape, and the lower side of the water flow delay measuring cylinder is provided with a water flow regulating valve 20, and the size of the overflow window 21 is changed by moving the water flow regulating valve 20 up and down, so as to control the outlet flow of the water flow delay measuring cylinder, wherein the overflow window 21 is higher than the seal valve 7 of the flushing port. The flow of the overflow window 21 of the water flow delay measuring cylinder is adjusted, so that the speed of the liquid level in the water flow delay measuring cylinder 4 descending when the sealing valve 7 of the flushing port fails and can not be closed can be realized, and the delay time of the water leakage failure to close the water supply valve 14 can be adjusted. The length of the control floating ball pull rope 2 determines the position point of the water flow delay measuring cylinder 4 at which the liquid level descends, namely the change of the area of the overflow window 21 is matched with the length of the control floating ball pull rope 2, and the delay time of the water leakage occurring to the closing of the upper water valve 14 is adjusted under the combined action of the change of the area of the overflow window and the length of the control floating ball pull rope 2

Fig. 3 is the schematic diagram of the water cut-off control lever of the present invention, the connection control floating ball end of the water cut-off control lever 12 is processed to have a saw-tooth shape, and the movement of the force arm adjusting slider 25 realizes the adjustment of the force arm acting on the water cut-off control lever 12 by the control floating ball 1, changes the torque of the water cut-off control lever 12 pulled when the control floating ball 1 acts, and adjusts the closing speed of the water feeding valve 14 when the seal valve 7 of the flushing port fails.

The foregoing is a detailed description of the invention and is intended to cover various modifications and changes within the scope of the invention and the appended claims, rather than to limit the scope of the invention, and therefore the described embodiments are not to be construed as limiting the scope of the invention as claimed.
