Piston-energy-storage toilet water flushing device

Abstract

The invention relates to water flushing devices, in particular to a piston-energy-storage toilet water flushing device which is extensively applied in houses of residents. The piston-energy-storage toilet water flushing device comprises a water inlet tap, small water tanks, a piston cylinder, a pressing rod, a four-way pipe, a piston, an offsetting spring, a side hole, a piston flow guiding hole, a drainage port and a mounting bracket. When the pressing rod is pressed, a piston valve is opened, high-energy water stored in the small water tanks passes through the side hole and piston flow guiding hole of the piston cylinder in the form of high-velocity jet flow and enters a toilet pedestal pan so as to flush dirt at a high speed, thus, water can be greatly saved while the flushing effect is guaranteed, and the duplication of labor of reduced.

Description

technical field [0001] The invention relates to a flushing device, in particular to a piston energy-storage toilet flusher widely used in households. Background technique [0002] Traditional toilet flushers are generally of the simple water storage type, that is, a water tank is specially installed at the rear of the toilet, and the water tank is connected to the atmosphere. When flushing, manually pull up the cover plate valve cover plate positioned at the bottom of the water tank, at this time, the previously accumulated quantitative water in the water tank gushes out to wash away the dirt. This kind of design generally consumes about 8L of water in one action. In addition, the flushing effect is not ideal, and the dirt often needs to be flushed several times, and the accumulated water consumption caused by repeated flushing is even more amazing. [0003] In recent years, due to the increasing shortage of drinking water resources for residents and the increasing awarenes...

AI Technical Summary

Problems solved by technology

[0005] 1. The water is weak: this is also the most fatal shortcoming of the old-fashioned flusher. The impact force of the water placed in the water tank is too small. Usually, one flushing action often fails to achieve the effect, and two or three flushes are required. The reason is because the water tank The water level stored in the tank is only 0.3 meters, and the potential energy formed is too small. In this way, when the potential energy becomes kinetic energy when the water gushes out, the resulting velocity head is very small, less than 2 meters per second. The water flows out slowly, and the resulting The scouring force is also negligible;

[0006] 2. The water tank has a large water storage capacity and consumes water: in order to ensure the flushing effect, the capacity of these water storage tanks is usually not too small, usually at the level of 8 liters, and once the water avoidance valve is opened, all the water contained will gush out. The flushing effect is not good, and then repeated flushing several times, the single and cumulative water consumption is very large, so it is a waste of water;

[0007] 3. A large water storage tank must be installed: the toilets on the market are generally divided into two types: split type and integrated type, but no matter which one is equipped with a special ceramic water storage tank, the water tank and the toilet together not only occupy a large area, but also ceramic The water tank is fragile, and a large amount of clay and fuel are consumed in the production process. At the same time, due to the large volume and low density of ceramics, the transportation logistics cost per unit volume is very high during product transportation, which indirectly wastes energy.

[0008] 4. Because the washing force of the water is too small, the dirt cannot be washed away several times, which directly affects the user's mood

[0009] 5. The sinking valve is not under pressure and will automatically open when the pressure is slightly higher; the lifting valve is difficult to open manually when the pressure is too high
