Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model relates to a water saving fixtures in public washroom, the structure is as shown in figure 1, including wash platform 5, wash platform 5 passes through the pipeline and is connected with pedal force (forcing) pump 9, still is provided with into water check valve 8 on the pipeline A13 between wash platform 5 and the pedal force (forcing) pump 9, and pedal force (forcing) pump 9 still is connected with circulation tank 3 through pipeline B14, still is provided with out water check valve 10 on the pipeline between pedal force (forcing) pump 9 and the circulation tank 3, and circulation tank 3 passes through the pipe connection with the squatting pan again.

The pedal pressure pump 9 is also provided with a supporting plate 4 for stepping on.

The pipe diameter of the pipe B14 is smaller than that of the pipe A13.

A filter 6 is arranged on a pipeline between the washbasin 5 and the water inlet one-way valve 8, and a dirty water filtering pipeline 7 is arranged at the bottom of the filter 6.

Inside vertical partition of circulation tank 3 is two boxes of outside feed water tank 15 and waste water reutilization case 16, and wherein, outside feed water tank 15 water inlet is connected with outside water source through outside water supply pipe 1, and waste water reutilization case 16 is connected with pedal force (forcing) pump 9 through pipeline B14, and outside feed water tank 15 and waste water reutilization case 16 still gather respectively through the pipeline and are connected to squatting pan 12, outside feed water tank 15 and waste water reutilization case 16 still are provided with two on the pipeline of the department of gathering with squatting pan 12 and are led to solenoid operated directional valve 11.

The top of the waste water secondary utilization tank 16 is also provided with a water level sensor 2, the water level sensor 2 and the two-position two-way electromagnetic directional valve 11 are both connected with a controller, and the controller can control the two-position two-way electromagnetic directional valve 11 through a water level signal of the water level sensor 2.

The utility model relates to a water-saving device for public washroom, the theory of operation as follows:

when a person walks to hand washing station 5 to wash hands, the person stands on support plate 4, the piston inside foot-operated pressure pump 9 is pushed by the person's own weight to move downwards, the water pressure at the outlet of pipe B14 is strong because the pipe diameter of pipe B14 is smaller than that of pipe A13, water inlet check valve 8 is closed, water outlet check valve 10 is opened, foot-operated pressure pump 9 presses water into waste water reutilization box 16, and water flowing down from hand washing station 5 does not enter foot-operated pressure pump 9 but is in filter 6.

When the person leaves the position after the hand washing is finished, the supporting plate 4 is acted by the internal spring force of the pedal pressurizing pump 9 to drive the piston of the pedal pressurizing valve 9 to move upwards. At this point, inlet check valve 8 is open, outlet check valve 10 is closed, and the upward movement of the piston draws water from filter 6 into foot pump 9, which in turn filters the water exiting wash station 5. The water previously pressed into the circulating water tank 3 can be used for flushing the squatting pan 12 next time.

Considering that the circulating water quantity of the wastewater secondary utilization tank 16 in the circulating water tank 3 possibly cannot meet the requirement of flushing, the water level sensor 2 is arranged in the wastewater secondary utilization tank, when the water level sensor 2 monitors that the water quantity of the wastewater secondary utilization tank 16 is insufficient, the two-position two-way electromagnetic directional valve 11 can be connected with the external water supply pipeline 1 to meet daily use, and when the water level sensor 2 detects that the water level of the wastewater secondary utilization tank 16 meets the requirement, the two-position two-way electromagnetic directional valve 11 is connected with the wastewater secondary utilization tank 16, so that secondary utilization of hand washing water is realized while daily use is not influenced.

Meanwhile, the situation that the pipeline of the washbasin is possibly blocked is considered, the dirty water filtering pipeline 7 is arranged at the bottom of the filter 6, and the pipeline of the washbasin is convenient to dredge and wash.

Fig. 1 shows that a single wash basin saves water and corresponds to a single toilet, and can be installed according to the number of wash basins in reality.

In daily life, most people generally wash their hands after going to a toilet for sanitation. And the water after washing hands in the public place can not be too dirty, the utility model discloses this process of then ingenious utilization, after will washing hands the water and filter, utilize the device to impress the water tank, realize the reutilization of washing hands water. And the water pump can reach the purpose of collecting waste water without electric power. In conclusion, the device is a high-efficiency, energy-saving and environment-friendly water-saving device for daily life.
