Description

Float type toilet tank leak-proof device

The invention belongs to a leak-proof design, and particularly refers to a float-type toilet water tank leak-proof device used on a toilet water tank. With this invented technology, if the water stored in the water tank is found to be abnormally reduced or even empty, it means that the toilet is leaking and needs to be repaired.

Toilet is an indispensable sanitary equipment in daily life. It is related to everyone's daily life and rest. It is used to flush human waste into sanitary sewers and maintain the cleanliness of living space.

As for the structure of the toilet, it roughly includes a body that collects waste, and a water tank that provides flushing water. Use a simple linkage tool to open the drain valve connecting the water tank to the body during use, and use the natural principle of water flowing to lower places to drain the toilet. The waste inside the body is flushed into the sanitary sewer, and then the drain valve is closed to allow the water tank to re-store water for the next use.

In order to achieve good hygienic results, a certain amount of water needs to be maintained when flushing the toilet. In addition, each person uses it several times a day, so the toilet is a device that consumes considerable water resources. Although many people work hard to improve water use efficiency and reduce water waste. , but because the working principle of the toilet remains unchanged, the amount of flushing water that can be saved is limited, and the effect is quite limited.

However, depletion of water resources is a common problem in countries all over the world. Water conservation is also a lifestyle strongly promoted by governments around the world. Retaining unnecessary water and accumulating less can greatly benefit the entire society.

In order to improve the water efficiency of the toilet, the inventor of this case relied on his long-term experience in decoration and leakage projects to sort out and analyze the causes of water waste. He found that a large part of it was leakage in the toilet body or the water tank. Although the flow rate of most leaks was not large, it continued After a period of time, the total amount of water leakage is also quite alarming, even more than normal water consumption.

Water tank leaks can be divided into open leaks and hidden leaks. Open leaks refer to corrosion and damage of the drain valve, so that the water tank continues to leak into the main body, or the water tank and main body are obviously damaged, and there is water accumulation on the surface of the water tank or on the ground. This type of open leakage problem , clearly visible to the naked eye, and usually repaired quickly. The main cause of water waste is hidden leakage.

In practice, the inventor of this case once received a case from a homeowner whose house had three toilets and was only rented to one tenant for several years. However, for some reason, the monthly bill always amounted to more than 1,000 yuan. , obviously does not meet the actual water consumption.

The homeowner told that he had previously contacted two groups of water and electricity contractors to solve the problem. The first group helped him install the pressure motor, but the water bill was still more than 1,000 yuan. The second group helped him dismantle the pressure motor. But in the end, the water bill still cost more than one thousand yuan, indicating that the problem has not been solved.

The inventor of this case is the third group of leak-catchers. After listening to the homeowner's handling process, he began to investigate the problem. After checking, there was no leakage in the pipeline. Finally, he went to the toilet and observed it for a long time, and found that the water stored in the toilet tank was leaking. Debris was constantly flowing around, and we knew there was abnormal water discharge. After disassembling the rubber drain valve, we found that the drain valve had long been deformed into a wavy shape and could not be closed tightly. It was obviously a very simple leakage problem, but it stumped several groups to catch the leak. Expert.

In order to solve the problem of toilet water leakage, many operators provide devices for detecting water leakage. They usually install sensors in the water tank, whether mechanical or electronic. When the water level in the water tank drops abnormally, a warning signal is issued. personnel to perform troubleshooting.

However, the conventional leak-proof design of toilet water tanks can only detect whether there is water leakage, but cannot prevent the continued occurrence of water leakage. When personnel are not on site or are negligent, it is easy to miss the leakage information, resulting in a large amount of water loss.

Secondly, when the water level in the water tank drops, the water inlet pipe will automatically start to fill the water. Under normal circumstances, there is no problem. However, if there is a water leakage, the lower level will drop slowly, and then the water inlet pipe will replenish water immediately, causing the water level to change very little, making the habit Know that the leak-proof design of the toilet tank cannot be detected and function.

In addition, the design of conventional toilet water tank leak-proof devices is often complex, and requires professionals to be assembled, tested, and subsequently maintained. Therefore, the installation cost is relatively high and is not a solution that ordinary families can consider.

From this point of view, it is obvious that the conventional technology still has huge problems that need to be solved, and it is not a perfect design.

In view of the aforementioned shortcomings, the inventor of the present case set out to make improvements and considered a simple and practical float-type toilet tank leak-proof device that can be installed by the user and then function to prevent water leakage.

In order to overcome the above shortcomings, the object of the present invention is to provide a float-type toilet water tank leakage prevention device that can automatically block the water inlet function of the water inlet pipe every time the water tank is filled with water to prevent the leakage from continuing due to the drop in water level. The action of water intake reduces the waste of water resources.

Another object of the present invention is to provide a float-type toilet water tank leak-proof device, which has a simple structure and is easy to assemble. Most people can easily assemble it by themselves. The cost is low, but the function is quite powerful.

In order to achieve the above objectives, the technical solution adopted by the present invention is to provide a float-type toilet water tank leakage prevention device, which includes a support arm, the upper and lower ends of the support arm are respectively fixed on the float connecting rod and the inside of the water tank, and the support arm There is a rotating shaft in the middle, and a pulling cable is provided on the rotating shaft, and the pulling cable extends to the outside of the water tank.

The action of the float-type toilet water tank leakage prevention device of the present invention completed by the above-mentioned structure is that when the toilet is flushed, the water level of the water tank drops, and at the same time, the float ball sinks to start the water inlet pipe filling. When the water tank is flushed, the water level of the water tank drops. When the water level rises and the float ball is pushed up to the water stop point of the water inlet pipe, in addition to stopping the water inflow, the support arm will straighten and resist the float ball, so that when the water level of the water tank drops due to water leakage, the float ball will The ball will not sink, preventing continuous water inflow and causing waste. When it is necessary to flush normally again, pull the cable to bend the rotating shaft, so that the floating ball returns to the normal working state, and the floating ball can be lowered after flushing. sink to start filling the water inlet pipe.

Furthermore, the support arm has an upper rod body and a lower rod body. One end of the upper rod body and the lower rod body has a lock for fixing to the float connecting rod and the inside of the water tank. The upper rod body and the lower rod body The other end of the rod body is inserted with a plug pin to form the rotatable shaft, so that the upper rod body, the lower rod body and the plug tip can be stored separately.

Furthermore, the upper rod body or the lower rod body is provided with a baffle at one end of the rotating shaft, so that the upper rod body and the lower rod body can only be bent toward one end of the rotating shaft to facilitate the operation of the cable.

Furthermore, the lock of the lower rod body is a set of rings, which is placed on the pipe column of the water inlet pipe, and the connecting end of the ring and the lower rod body is provided with a rotor to facilitate the lower rod. The body moves up and down.

A cable 340 is provided on the rotating shaft 330 , and the cable 340 extends to the outside of the water tank 200 .

With the aforementioned device, when the toilet is flushed, the water level of the water tank 200 will drop rapidly, causing the float ball 220 to sink and start the water inlet pipe 210 to fill the water. When the water level of the water tank 200 rises again, the float ball 220 will be flushed. When the ball 220 is pushed up to the water stop point of the water inlet pipe 210, in addition to stopping the water inflow, the support arm 300 will straighten and resist the floating ball 220, so that the floating ball 220 will no longer follow the movement of the water tank 200. The water level drops and sinks. In this way, if the water level of the water tank 200 gradually drops due to water leakage, the floating ball 220 will still not sink. Therefore, continuous water inflow must be prevented to avoid waste; and when normal flushing is to be resumed, the float ball 220 needs to be pulled. The cable 340 bends the rotating shaft 330, unlocks the restriction of the support arm 300, and returns the float 220 to the normal working state. The float 220 is allowed to sink after flushing to start the water filling of the water inlet pipe 210. Wait until the water filling is completed. use.
