When the cistern discharge valve 10 is opened, the cistern of the toilet discharges water, the overflow pipe 101 rises and triggers the discharge valve 2 to open. When the water tank of the toilet has finished discharging water, the water tank discharge valve 10 is closed, the water tank of the toilet starts storing water, the overflow pipe 101 descends and leaves the discharge valve 2, and the discharge valve 2 is closed.

When mounted, the drain valve 2 is directed towards the overflow pipe 101 for supplying the cleaning liquid 7 into the overflow pipe 101, the cleaning liquid 7 will be discharged from the overflow pipe 101 and mixed with the water discharged from the tank of the toilet for flushing the ceramic body of the toilet.

In one embodiment, the inlet valve 3 comprises more than two water flow adjustment positions.

In this embodiment, the water inlet valve 3 is located at each water flow adjusting gear and can control different water inflow or water supplement amount, so that the single water inflow or water supplement amount of the liquid storage tank 1 can be controlled in multiple gears, and the single liquid discharge amount of the liquid storage tank 1 can be controlled in multiple gears.

In one embodiment, as shown in FIGS. 1-4, the inlet valve 3 includes an inlet valve housing 31 and an inlet valve core 32.

The inlet valve housing 31 has a water flow passage 311 therein, and the water flow passage 311 communicates with the reservoir 1.

The control valve core 32 may be a telescopic core or a rotary core, and may change the water flow rate of the water flow channel 311 flowing to the water inlet of the liquid storage tank. For example, the control valve spool 32 may vary the amount of water flow to the tank inlet by blocking the water flow passage 311.

In one embodiment, as shown in fig. 1 to 4, the inlet valve housing 31 is provided with a water diversion hole 312 communicated with the water flow passage 311, and a water replenishing pipe 33 is connected between the water diversion hole 312 and the liquid storage tank 1.

In this embodiment, the water diversion hole 312 is provided on the inlet valve housing 31, and compared with the sectional area of the water flow channel 311, the opening of the water diversion hole 312 is smaller, accordingly, the water flow rate flowing into the liquid storage tank 1 through the water diversion hole 312 and the water replenishing pipe 33 is also smaller, and the cleaning solution 7 overflowing from the liquid storage tank 1 due to excessive water flowing into the liquid storage tank 1 can be avoided.

In one embodiment, as shown in FIGS. 1-4, the inlet valve 3 further includes a return conduit 35 for returning excess water in the flow path 311.

The inlet valve housing 31 is provided with a return hole 313 communicating with the water flow passage 311, and the return pipe 35 communicates with the return hole 313.

Inlet valve spool 32 may be capable of controlling the opening and closing of return orifice 313 and/or may be capable of controlling the opening size of return orifice 313.

In this embodiment, the inlet valve housing 31 is provided with a return hole 313, and the return hole 313 is connected to the return pipe 35 through the bypass pipe 34.

When installed, a return pipe 35 is inserted into the tank of the toilet for returning excess water.

A part of the valve core 32 of the control valve is positioned above the return hole 313, so that the return hole 313 can be opened or closed by moving or the opening size of the return hole 313 can be controlled, the return water flow of the return hole 313 can be adjusted, and the water inflow or the water supplement amount flowing to the liquid storage tank 1 in the water flow passage 311 can be adjusted.

The flow of water in the water flow passage 311 is substantially constant. When the return water amount of the return hole 313 is large, the amount of the makeup water flowing into the reservoir 1 in the water flow path 311 is relatively small; when the return water amount of the return hole 313 is small, the amount of the makeup water flowing into the reservoir 1 in the water flow path 311 is relatively large.

The control valve spool 32 may be a telescopic spool or a rotary spool to control the opening and closing or opening size of the return orifice 313.

When the water diversion hole 312 is used for supplementing water into the liquid storage tank 1, the backflow hole 313 and the water diversion hole 312 are arranged in the following way:

in the water flow direction along the water flow channel 311, the return hole 313 is located at the upstream of the water diversion hole 312, and the water flow entering the water diversion hole 313 can be changed by controlling the opening and closing or opening of the return hole 313, that is, the water replenishing amount to the liquid storage tank 1 is controlled.

In one embodiment, as shown in FIG. 3, a handle portion 321 is attached to the inlet valve cartridge 32, the handle portion 321 being outside of the inlet valve housing 31.

In this embodiment, by providing the handle portion 321, an operator can manipulate the handle portion 321 to drive the inlet valve core 32 to rotate or extend and retract, so that the inlet valve core 32 moves to open and close the return hole 313 or control the opening size of the return hole 313.

In one embodiment, as shown in FIGS. 3-4, inlet valve spool 32 is rotatably mounted to inlet valve housing 31.

Inlet valve spool 32 is positioned at least partially above return orifice 313 and is configured to rotatably open and close return orifice 313 and/or control the size of opening return orifice 313.

In this embodiment, the inlet valve core 32 is a rotary valve core, and the inlet valve core 32 and the inlet valve housing 31 are pivotally connected. At least a portion of inlet valve spool 32 extends above return orifice 313.

Inlet valve spool 32 may be configured to rotatably open and close return orifice 313 and/or control the opening size of return orifice 313. Namely: when the inlet valve spool 32 is rotated to the first position, the inlet valve spool 32 closes the return orifice 313, and when the inlet valve spool 32 is rotated to the second position, the inlet valve spool 32 opens the return orifice 313. As inlet valve spool 32 rotates between the first position and the second position, inlet valve spool 32 changes the opening size of return orifice 313. The closer the inlet valve spool 32 is to the second position, the larger the opening area through which water can pass through the return hole 313. The closer the inlet valve spool 32 is to the first position, the smaller the opening area through which water can pass through the return hole 313.

In one embodiment, as shown in FIG. 5, inlet valve spool 32 includes a cylindrical portion 323 and a cut-out portion 324.

The cylindrical portion 323 can seal the return hole 313 with the rotation of the inlet valve core 32.

The notch portion 324 is capable of communicating the return orifice 313 with the water flow path 311 in response to rotation of the inlet valve spool 32.

In this embodiment, inlet valve core 32 includes a cylindrical portion 323 and a cut-out portion 324, and cylindrical portion 323 and cut-out portion 324 are disposed opposite to each other or spaced apart from each other. The inlet valve core 32 is a cylindrical body, and a cut portion 324 is formed by cutting a part of one side, and a cylindrical surface portion 323 is an uncut portion.

As the inlet valve core 32 rotates, the cylindrical portion 323 may completely cover the return orifice 313 to completely close the return orifice 313 when the cylindrical portion 323 rotates to the bottom.

When the cut-out portion 324 is rotated to the bottom along with the rotation of the inlet valve core 32, a gap is formed between the cut-out portion 324 and the return hole 313, the return hole 313 is communicated with the water flow channel 311, and part of water in the water flow channel 311 can flow back to a water tank of the toilet through the return hole 313, the bypass pipe 34 and the return pipe 35.

An operator may change the opening size of the return hole 313 by changing the rotation angle of the inlet valve core 32 such that a part of the cylindrical portion 323 covers the return hole 313 to close a part of the return hole 313, and at this time, another part of the return hole 313 communicates with the water flow path 311 through the cut portion 324.

In one embodiment, as shown in fig. 1-2, the tank outlet 12 is arranged in a tank side wall 11 of the tank 1.

In this embodiment, liquid reserve tank liquid outlet 12 sets up on liquid reserve tank lateral wall 11 of liquid reserve tank 1, and its bottom plate that is higher than liquid reserve tank 1 can keep keeping water to dissolve clean pellet 6 in liquid reserve tank 1 all the time to form cleaning solution 7.

In one embodiment, as shown in fig. 1-2, the tank 1 has a first predetermined level 13 and a second predetermined level 14 above the first predetermined level 13.

When the drain valve 2 is in a closed state, the inlet valve 3 is opened and the cleaning liquid 7 in the reservoir 1 is accumulated and rises to a second preset level 14.

When the drain valve 2 is in an open state, the inlet valve 3 is closed and the cleaning liquid 7 in the reservoir 1 is drained and lowered to a first preset level 13.

In this embodiment, a first predetermined level 13 and a second predetermined level 14 are pre-established in the tank 1 in order to achieve a dosed supply of cleaning liquid 7. The second preset level 14 may be a high level and the first preset level 13 may be a low level.

The first preset liquid level 13 can be controlled through a liquid storage tank liquid outlet 12 arranged on the side wall 11 of the liquid storage tank, and the bottom of the liquid storage tank liquid outlet 12 and the first preset liquid level 13 are in the same horizontal plane. If the liquid level of the cleaning liquid 7 in the liquid storage tank 1 is higher than the first preset liquid level 13, the cleaning liquid 7 can be discharged from the liquid outlet 12 of the liquid storage tank; if the level of the cleaning liquid 7 in the tank 1 is at or below the first predetermined level 13, the cleaning liquid 7 is no longer drained from the tank drain 12.

The second predetermined level 14 may be pre-designed, and is determined by the single water inflow or the single water supplement amount of the water inlet valve 3, and the height of the second predetermined level 14 may be adjusted by adjusting the single water inflow or the single water supplement amount of the water inlet valve 3.

When the water tank of the closestool stores water, the water discharge valve 10 of the water tank is kept closed, the liquid discharge valve 2 is kept closed, the water inlet valve of the water tank is opened, and the water supply pipe 4 supplies water to the liquid storage tank 1 through the water inlet valve 3. After the water tank of the toilet is full of water, the water inlet valve of the water tank is closed, the water supply pipe 4 stops supplying water, the liquid storage tank 1 also stops supplying water, and the liquid level of the cleaning liquid 7 is at the second preset liquid level 14.

When the water tank of the closestool discharges water, the water inlet valve of the water tank is kept closed, the water discharge valve 10 of the water tank is opened, the liquid discharge valve 2 is opened, the cleaning solution 7 in the liquid storage tank 1 is discharged from the liquid discharge port 12 of the liquid storage tank through the liquid discharge pipe 5 and the liquid discharge valve 2 and enters the overflow pipe 101, and then is discharged from the overflow pipe 101 and mixed with the water discharged from the water tank to wash the ceramic body of the closestool. After the cleaning liquid 7 has fallen from the second predetermined level 14 to the first predetermined level 13, the cleaning liquid 7 can no longer be discharged from the tank drain 12. After the water tank finishes draining, the drain valve 10 of the water tank is closed, the inlet valve of the water tank is opened, the water tank starts storing water, and the liquid storage tank 1 starts replenishing water.

Based on the above analysis, the amount of cleaning liquid 7 provided by the reservoir 1 at a single time is: the volume of cleaning liquid between the second predetermined level 14 and the first predetermined level 13. When the water tank of the closestool discharges water every time, the outlet liquid 1 can provide a certain amount of cleaning liquid 7 to flush the ceramic body of the closestool, so that the waste of the cleaning liquid 7 is avoided.

In one embodiment, as shown in fig. 1-2 and 6-8, the drain valve 2 includes a drain valve housing 21 having a chamber 211 and a drain valve spool 22 slidably coupled to the drain valve housing 21.

The drain valve spool 22 can control the opening and closing of the chamber outlet port 213.

In this embodiment, the chamber inlet 212 is in communication with the reservoir outlet 12 via a drain 5. At least part of the drain valve spool 22 is located in the chamber 211, and the drain valve spool 22 is slidably connected to the drain valve housing 21. The valve core 22 of the drain valve can move or slide to control the opening and closing of the chamber outlet 213 through a convex portion, a plug portion, an end cap portion, or the like on the valve core 22 of the drain valve.

The drain valve spool 22 may be interlocked with the overflow pipe 101 of the tank drain valve 10. The drain valve spool 22 can be lifted by the overflow pipe 101 in the tank drain valve 10 of the cistern, thereby opening the chamber outlet 213 and the drain valve 2. At this time, the cleaning liquid 7 in the liquid storage tank 1 can enter the chamber 211 through the liquid discharge pipe 5 and then be discharged into the overflow pipe 101 through the chamber liquid outlet 213. After the overflow pipe 101 descends, the overflow pipe 101 is separated from the drain valve spool 22, the drain valve spool 22 falls to close the chamber outlet 213, and the drain valve 2 is closed. Overflow tube 101 may contact drain valve spool 22 via a boss, link, or linkage, thereby jacking up drain valve spool 22. The boss, link or linkage is not shown in the figures and may be as in the prior art.

In one embodiment, as shown in fig. 7-8, drain valve spool 22 includes a plug 221 for controlling the opening and closing of chamber outlet 213. Plug 221 is slidably mounted in cavity 211.

In this embodiment, the valve core 22 of the drain valve includes a plug 221, and the plug 221 is used for controlling the opening and closing of the chamber liquid outlet 213. The plug 221 is fitted in the chamber 211, and the plug 221 can slide up and down in the chamber 211. A vertical guide mechanism (e.g., a guide groove, a rail, etc.) may be provided between the plug 221 and the wall of the chamber 211 to guide the plug 221 to slide up and down.

When the drain valve spool 22 is lifted, the plug 221 is then moved upward in the chamber 211 away from the chamber outlet port 213, thereby opening the chamber outlet port 213, and the drain valve 2 is opened.

When the drain valve spool 22 falls, the plug 221 moves downward in the chamber 211 to cover the chamber outlet port 213, thereby closing the chamber outlet port 213, and the drain valve 2 is closed.

In one embodiment, as shown in fig. 6-8, a reset driving member for driving the drain valve spool 22 to reset to close the chamber outlet 213 is installed between the drain valve housing 21 and the drain valve spool 22.

In this embodiment, the reset driving member may be a reset mechanism such as a spring and a magnet.

When the overflow pipe 101 ascends, the valve core 22 of the drain valve can be jacked up and drive the plug 221 to move upwards to open the chamber liquid outlet 213 against the action force of the reset driving piece.

After the overflow pipe 101 descends, the reset driving member is used for driving the plug 221 to fall and cover the chamber outlet 213, thereby closing the chamber outlet 213.

In one embodiment, as shown in figures 6-8, the reset actuator comprises a first magnet 8 and a second magnet 9 capable of attracting each other.
