Toilet flushing system with injection pump

Abstract

The invention discloses a toilet flushing system with an injection pump. The toilet flushing system comprises a flushing water system and a water saving system, wherein the flushing water system comprises a tap water control solenoid valve, the injection pump, a liquid level measurement float switch and a flushing water control solenoid valve, and the water saving system comprises the injection pump, an air control solenoid valve, a high-liquid-level measurement float switch, a low-liquid-level measurement float switch, a water sucking control solenoid valve and a siphon water release control solenoid valve. According to the toilet flushing system, the injection pump is added, so that part of pressure energy of the tap water is recycled, and the part of energy is used for recycling part of water for urine flushing of the toilet; during the faces flushing, the recycled water is drained into a drain pipeline of the toilet earlier than the flushing water of the toilet, siphon force is generated for sucking dirt such as feces, and then the water with the amount being equal to that of the water used for flushing urine is released for flushing the toilet to be clean. Compared with the existing water-saving toilet, the toilet flushing system provided by the invention has the advantage that the amount of the water for flushing the feces is reduced by one half.

Description

technical field [0001] The invention belongs to the technical field of water saving, in particular to a toilet flushing system. Background technique [0002] In order to achieve the water-saving purpose of the toilet, people have made a lot of improvements to the existing toilet flushing system, such as: improving the linearity of the water flow in the design of the toilet to generate a swirl; changing the internal structure of the toilet flushing water flow , change the outlet position of the flushing water; change the structure of the toilet's sewer channel; improve the state of the inner wall of the toilet, etc., but when defecating, because there are more dirt and solids, it must rely on a large amount of water to wash away, and at the same time Relying on the siphon force generated by the flushing water flow to discharge sewage makes the flushing water volume of stool much larger than that of urinating, and it cannot be reduced, which has become a bottleneck for toilet ...

The existing double-chamber toilet recycles the sewage from the washbasin, which is released together with the tap water to flush the toilet when the toilet is flushed. Although this saves water, the flushing water contains sewage, which will cause the toilet wall to not be flushed clean , the water seal water at the bottom of the toilet is not clean and easy to breed bacteria. At the same time, the collection of basin drainage water is limited by the installation position of the basin. If the basin is installed far away from the toilet, the installation of the piping system will not change, which will give The installation and use of double-chamber water-saving toilets cause certain restrictions
