Problems solved by technology

This type of toilet water inlet valve and other toilet components often fail, such as obstructions in the toilet drain pipe that cause the toilet to block, causing the toilet to overflow when the toilet is flushed, and then damage the surrounding objects
This known toilet water inlet valve does not provide the function of cutting off the water supply that is beneficial to reduce losses when the water level of the toilet bowl is at a high water level
[0003] In addition, when the liquid level in the toilet water tank of this known toilet water inlet valve reaches the full water level, the water supply cannot be cut off if there is a failure, which will lead to leakage and waste a lot of water resources
Therefore, when the liquid level of the toilet tank reaches a high water level, if the overflowing water cannot be continuously discharged to the auxiliary drainage device provided by the toilet, it will cause the toilet tank to overflow, causing the loss of the surrounding objects again.
[0004] Known toilet flush valves also often break down. For example, the flush valve may be stuck in the open position, causing the liquid level of the water tank to fail to rise all the time, causing the water inlet valve to continuously supply water, resulting in wasting a lot of water resources. In more serious cases, this The toilet flush valve may be leaking, allowing the fluid level in the tank to slowly drop until the float reaches the set point that opens the inlet valve
Normally, the water entering the tank from the inlet valve is much faster than the water leaking from the flush valve, so the float will not close the inlet valve until the tank level rises to the set point, but the flush valve will still Continuous leakage, followed by repeated water injection into the water tank, resulting in wasting a lot of water resources and increasing the user's operating costs
In the known technology, none of the toilet water inlet valves can provide the function of cutting off the water supply to prevent waste when an abnormal condition of the flush valve is detected

Embodiment 1

[0045] Example 1: see Figure 1-7 , a toilet water inlet valve automatic closing structure, has a water inlet valve float structure 26 that lifts the floating arm 16, to correspond to the rising water level 8 of the toilet water tank 9, the floating arm 16 is controlled by the water inlet valve float structure 26 Lift up, and then close the toilet water inlet valve 10; Also include:

[0046] An auxiliary transmission 11 comprising a slidable piston 13 vertically mounted on the bottom of the float arm 16 which lifts the float arm 16 when the piston 13 is in the raised position 50 to fully close the toilet inlet valve 10 ; An eccentric device 15 pushes the piston 13 up to the rising position 50 .

[0047] A solenoid structure 18 is normally de-energized and slidingly engages the locking structure 17 of the piston 13 when the piston 13 is in the lowered position 40; when energized, the solenoid structure 18 is disengaged from the locking structure 17 so that The piston 13 is pu...

Embodiment 2

[0058] Embodiment 2: In this embodiment, except for the eccentric device 15 , the others are basically the same as the above embodiments, so details are not repeated here.

[0059] See Figure 8-9 , the eccentric device 15 is a hydraulic structure 200 driven by the water pressure of the toilet water inlet valve 10 . In this embodiment, the electromagnetic control valve 210 is usually in a power-off state, so as to moderately block the water pressure of the toilet water inlet valve 10 caused by the lifting of the piston 13, so as to facilitate closing the toilet water inlet valve 10. The solenoid structure 211 belongs to the push type rather than the pull type shown in the above-mentioned embodiments. Both types can be used. The solenoid 211 blocks the toilet water inlet valve 10 pressure measurement when the solenoid 211 is de-energized and the spool 214 is in its normal position. The water pressure of the hole 213 can be obtained from the toilet water inlet valve 10 or other...

Abstract

An automatic closing structure for a toilet water inlet valve, which has a water inlet valve float structure for raising a floating arm, and the floating arm is lifted upward by the water inlet valve float structure, and then closes the toilet water inlet valve; it also includes: a The auxiliary transmission device includes a slidable piston vertically arranged at the bottom of the floating arm and an eccentric device pushing the slidable piston upward, the piston is installed in the piston housing, and the eccentric device is arranged on the piston Below; a solenoid structure slidingly engaged with the locking structure of the piston; an electronic sensing circuit having at least one sensor and a power supply, said electronic sensing circuit being electrically connected to The solenoid structure. The invention is a device capable of automatically closing the water inlet valve of the toilet by detecting abnormal conditions such as the abnormal high water level of the flush toilet and the water tank of the toilet, the flushing valve being stuck in the open position, and the flushing valve leaking.

Description

technical field [0001] The invention relates to the technical field of toilets, in particular to an automatic closing structure of a toilet water inlet valve. Background technique [0002] The known toilet water inlet valve includes a water inlet valve float structure that raises the floating arm to correspond to the rising water level of the toilet tank, and the floating arm is lifted upward by the water inlet valve float structure, thereby closing the toilet water inlet valve . This toilet water inlet valve and other toilet parts and components often break down, cause the toilet to block as the blockage in the toilet drain pipe, cause the toilet to overflow when flushing, and then damage the surrounding objects. This known toilet water inlet valve does not provide the function of cutting off the water supply which is beneficial to reduce the loss when the liquid level of the toilet bowl is at a high water level. [0003] In addition, when the liquid level in the toilet w...
