Description
Technical Field
The utility model relates to a bath lavatory technical field, especially a simple and easy automatic flushing system in ditch slot type bathroom.
Background
At present, in public places such as schools, stations, office buildings and the like, if the adopted toilet is arranged in the toilet, the toilet is often blocked due to poor flushing effect and insufficient flushing force, if the toilet cannot be dredged manually in time, the use and the environmental sanitation of the toilet are affected, a bad smell is generated for a long time to damage the image of the place, infectious diseases are seriously caused, and the body health of people is affected. The existing groove type public washroom flushing technology has the following defects:
1. the flushing effect is poor, and the impulsive force is not enough:
a plurality of groove type toilets adopt a traditional mechanical flushing mode, and often because of mechanical failure, large-flow running water cannot be instantly provided, so that the flushing force is insufficient, excrement cannot be flushed away at one time to form accumulated pressure, and sanitary events of toilet blockage and stink are caused. The small flow flushing is a waste, and the effect of flushing for multiple times is not good. This drawback is particularly evident in the case of insufficient tap water pressure or small water pipes. Particularly, in places such as schools and the like with large flow and frequent use, if a groove-type toilet is used in a public washroom and a traditional mechanical flushing mode is adopted, the phenomenon of excrement accumulation caused by the problems of small flushing force and the like of the washroom is more serious.
2. Water resource waste, the reliability is low:
the utility model provides a public health bath system who now commonly uses, mechanical type bath: the water storage tank is flushed by utilizing the principle of mechanical force balance or pressure balance, and when the gravity center or pressure is unbalanced after the water storage tank is filled to a certain degree, water in the water storage tank is poured to achieve the flushing effect. The public washroom flushing system adopting the mode can provide larger flushing force, but needs to continuously boil the water faucet all day long to flow, does not stop working without flushing, and does not play a role in saving water. The reliability of the mechanical flushing is low, and once a mechanical fault occurs, the flushing is long-flowing water, so that the flushing effect is poor, and water resources are wasted. Secondly, semi-automatic flushing: the water flushing system combines the induction switch with the water storage barrel, the induction switch controls tap water to be supplied to the water storage barrel, the water storage barrel is flushed by pouring water in the prior art depending on the balance of force or pressure, and compared with the mechanical flushing, the mode saves water, but has the defect of untimely flushing and also has the condition of excessive water supply in the induction time. And the reliability of the mechanical part is lower, once a mechanical fault occurs, the phenomena of long-flowing water or water pouring, flushing and overflowing cannot occur, the flushing effect cannot be achieved, and the waste of water resources is also realized. Thirdly, flushing by a flushing valve: the flushing mode is controlled electronically or manually, is greatly influenced by the limitation of water pressure and water pipe size, and because the flushing valve without the water storage tank is directly connected to the tap water pipe, the condition of insufficient water flow and flushing force exists, the flushing effect is worse particularly on high floors with low water pressure, and the flushing party can only be used for a single squatting pan. The poor flushing effect is also a waste of water resources.
