Flushing device

Abstract

The invention discloses a flushing device. The flushing device comprises a closestool composed of a water tank and a seat body, a water inlet valve and a drain valve are arranged in the water tank, ahydraulic button capable of allowing water to pass through is further arranged between the water inlet valve and the drain valve, and a first connecting pipe is arranged between the hydraulic button and the water inlet valve. A second connecting pipe is arranged between the hydraulic button and the drain valve, the drain valve is provided with a water tank drainage channel and a hydraulic button drainage channel, and water tank water flowing out of the water tank drainage channel and button water flowing out of the hydraulic button drainage channel are mixed and then flow out of a drainage port in the drain valve. By means of the structural design and the double-water-path structural design, the impact force after water flow mixing is enhanced, and the overall structural size of the product is greatly reduced.

Problems solved by technology

[0002] The toilet generally includes two parts: the toilet seat and the water tank. An inlet and outlet valve is installed in the water tank to flush the toilet. It is very bulky and takes up a lot of bathroom space. At the same time, the production failure rate of ceramic toilets is high and the cost is high;

[0003] In order to pursue better flushing effect and less flushing in the bathroom industry, the method of continuously increasing the drain diameter of the drain valve has been adopted, from the previous common 2-inch drain valve to the 3-inch drain valve, and even 3.5-inch to 4-inch drain valves. Drain valve; the adverse consequence of simply increasing the diameter of the drain valve is that the toilet tank is getting bigger and bigger, and the cost of the drain valve is getting higher and higher;

[0004] In addition, the mainstream in European countries is the wall-mounted toilet with a hidden water tank. The market requires that the hidden water tank is getting thinner and thinner, which can reduce the space occupied by the false wall. However, the current ordinary drain valve can only reduce the drainage if it wants to make the water tank very thin. The drain diameter of the valve, for example, there is a 1.5-inch drain valve on the market, but the momentum provided by such a small drain valve is not satisfactory, so the hidden water tank system of thin water tanks cannot be popularized in the market;

[0005] At present, pressure flush toilets are gradually increasing in the Asia-Pacific and North American markets. There are two main types. One is to use a thick hose to connect the tap water system to directly flush the toilet through a solenoid valve control switch, and the other is to use a closed water tank to store tap water. The pressure of the system releases the water pressure to flush the toilet instantly through the flush valve switch; this kind of pure use of water pressure to flush water has certain defects. The first type of water pipe directly flushes water needs to use solenoid valves or water pumps and very thick soft Pipe, the service life is unreliable, and the flushing water is unstable due to the influence of the surrounding water points; the second type of pressure flushing water tank is generally large in size, either the water tank is very large, or the toilet is very long, and the cost is high, which is not conducive to Marketing popularization
