Description
Technical Field
The invention relates to the field of toilets, in particular to a toilet bowl with the following patent application publication numbers: toilet bowl in CN 104264756A.
Background
In the toilet water tank in the patent, the piston and the inner wall of the tank body have friction in the using process of the water tank, so that leakage occurs in sealing between the piston and the tank body, and when the toilet is in a static state, if the leakage exists in the water tank, water flows out of the water tank through the water outlet pipeline, and water waste is formed.
In the stool pot water tank, the water of piston both sides need circulate, and valve opening, pipeline are thinner on the water tank circulation pipeline, and the water process of water tank circulation valve, pipeline, if there is impurity in the water, make valve, pipeline jam very easily, the water through the valve is a direction all the time moreover, and the valve, the pipeline of jam hardly obtain rivers from the mediation to can more and more stifled under the majority condition, influence the water tank normal use.
The toilet stool water tank of above-mentioned patent, the piston pull rod all is overall structure, so longer, and occupation space is relatively, and the water tank cylinder is worn out to the piston pull rod moreover, because the water tank is inclosed, the pull rod can receive the certain resistance of sealing washer at the flexible in-process of water tank cylinder, is unfavorable for the use, and influences life. If the water tank wants to adjust the maximum water adding amount, the water tank is difficult to adjust, the length of the pull rod extending out of the cylinder barrel can be changed, and potential collision can be caused to water tank parts around the pull rod.
In the patent, the water outlet pipeline of the water tank is thick and has a certain length, the water outlet pipeline is thick and the valve volume is large, if the water tank and the water outlet pipeline valve are arranged on the ground around a squatting pan and a urinal or around a toilet, the installation is complex, the articles around the toilet are more and not beautiful, and the fault maintenance of the water tank and the valve is inconvenient; if the water tank is arranged on the wall around the toilet, the water inlet and outlet pipeline between the valve on the ground and the water tank occupies larger space, and the longer pipeline can reduce the flushing pressure.
Install the water tank valve on ground, when valve pressure conduction board rose, descended, the conduction board was inevitable to have the gap with ground on every side, and dust, the water droplet on ground can be inevitable to get into the gap to cause the hidden danger that the valve broke down, there is the potential safety hazard in the gap in addition.
Disclosure of Invention
The invention relates to a toilet water tank plugging device, which solves the problem of leakage of water in a water tank when a toilet is static and also solves the problems that a water tank valve is easy to block and is difficult to dredge.
The piston is provided with a water flowing channel 51 or a water flowing gap penetrating through the piston or the water flowing gap is arranged between the water tank cylinder barrel and the piston, so that water on two sides of the water tank piston can circulate.

The second sealing mode is as follows: the plugging device is set to be a circle of bulge at the bottom of the water tank, the water tank comprises a circle of elastic bulge 20, the elastic bulge is positioned at the bottom of the water tank, and when the piston is positioned at the bottom of the water tank, the elastic bulge and the bottom of the piston are correspondingly sealed.
The tank comprises a ring of projections 20, which may not be elastic projections, and the corresponding sealing surfaces are elastic.
When the toilet water tank is static, the water tank piston is positioned at the lowest end of the water tank, and the piston is tightly pressed with a circle of elastic seal at the lower bottom of the water tank by the pressure on the upper surface of the piston to form a second seal of the water tank.
The third sealing mode is as follows: a circle of bulges 55 are arranged at the tail end or the periphery of the plugging device and are sealed corresponding to the position outside the opening of the main pipeline at the lower bottom of the water tank, so that the main pipeline is plugged. Or the blocking device is arranged as a circle of bulge at the lower bottom of the piston, the water tank comprises a circle of elastic bulge 55 at the lower bottom of the piston, and the elastic bulge is correspondingly sealed with the lower bottom of the water tank. The diameter of the circle of the bulge can be larger or smaller.
The tank includes a ring of projections 55, which may not be resilient projections, and the corresponding sealing surfaces are resilient.
When the toilet water tank is static, the water tank piston is positioned at the lowest end of the water tank, and the upper surface of the piston is pressed, so that the seal of the lower bottom of the piston is tightly pressed with the lower bottom of the water tank to form a second seal of the water tank.

The fifth sealing mode is as follows: the water tank is characterized in that the plugging device is of a columnar structure, a valve is opened by self-force return in a main pipeline of the water tank, when the water tank is idle or water flows through the water tank, the valve is opened, when a water tank is flushed to the bottom, a piston of the water tank moves downwards to the bottom, the piston plugging device is contacted with the valve through the columnar structure of the piston, water pressure continues to push the piston to move downwards, and therefore the plugging device moves downwards to close the valve. When water is added into the water tank, the piston moves upwards, and the valve is automatically restored to be opened.
When the water tank is flushed, the blocking device moves downwards from the upper part of the water tank, finally the main pipeline of the water tank is sealed and static, and when leakage exists between the piston and the inner wall of the toilet, the leaked water is blocked in the water tank by the blocking device.
When the water tank begins to work next time, inlet channel valve 5 is opened, and outlet channel valve 6 is closed, and the water tank has two kinds of circumstances:
the first condition, if there is leakage in water tank piston and water tank inner wall, the water pressure of piston both sides equals and can have the circulation, and the water pressure of inlet channel 3 acts on water tank plugging device terminal surface, and the pressure that the piston lower part receives just is greater than the pressure that piston upper portion received, and the piston begins the rebound, and the water tank begins the work of adding water, and plugging device is not in shutoff water tank main conduit moreover.
In the second situation, if the water tank piston and the inner wall of the water tank are not leaked, the water pressure on two sides of the piston are equal but can not be circulated, the water pressure of the water inlet pipeline 3 acts on the end face of the water tank plugging device, the pressure on the lower part of the piston is greater than the pressure on the upper part of the piston, the piston starts to move slightly upwards, then the pressure on the lower part of the water tank piston is smaller than the pressure on the upper part of the piston and the water pressure of the water inlet pipeline 3 on the end face of the plunger, water passes through the plugging device or the sealing ring through the second water inlet pipeline 3 to enter the water tank.
