Description

A low-water tank toilet flushing system and toilet with enhanced momentum

technical field

The utility model relates to the field of toilets, in particular to a low-water tank toilet flushing system with enhanced momentum and a toilet having the low-water tank toilet flushing system with the enhanced momentum.

Background technique

The toilet (toilet) generally includes two parts: the toilet seat and the water tank. An inlet and a drain valve is installed in the water tank to flush the toilet. In order to ensure that the toilet has sufficient flushing power, the water tank is generally made very high to use the gravitational potential energy of water to flush. Toilet cleaning is cumbersome and takes up a lot of bathroom space. At the same time, the production defect rate of ceramic toilets is high and the cost is high.

In addition, there are some toilets with very low water tanks or even tankless toilets on the market. There are two typical types. One is a silent tankless toilet. The valve is combined with a venturi tube to increase the flow to flush the toilet, but the obvious disadvantage is that the flushing force is very weak, and it can only be used as an ordinary non-water-saving 6L toilet; the second type is more and more intelligent integration in China, Japan and South Korea. Most of the toilets directly use the pressure of the water supply system to flush the toilet directly or indirectly through the enlarged hose. Most of this flushing system realizes the toilet flushing through the opening and closing of the solenoid valve. This flushing system is very obvious. The disadvantage is that the impulse is also very weak, and the life of the solenoid valve is not high and it is easy to break.

At present, there is also a structure of an air-storage water tank on the market. The air-storage water tank injects water into the water tank and compresses the air to a certain pressure. When flushing is required, just press the flush switch, and the air pressure in the water tank acts as a pressure booster. It can make flushing more powerful and can solve the problem of insufficient impulse. However, in the existing structure, since the air-storage water tank and the drainage mechanism matched with it both need to be assembled into the toilet body, the existing air-storage water tank and the drainage mechanism are both integrated structures, that is, the air-storage water tank and the drainage mechanism are assembled in one piece. After the drainage mechanism is assembled, it is completely put into the toilet body. When it needs to be disassembled, it is also necessary to take out the assembly structure of the entire air storage tank and the drainage mechanism, and then disassemble and replace according to the assembly structure, which is not easy to disassemble.
