Description

water saving toilet

technical field

The utility model relates to a toilet, in particular to a water-saving toilet.

Background technique

As we all know, nearly 70% of our earth's surface is covered by water, but fresh water resources are limited, and many countries are facing the threat of water shortage, especially in China. When washing, people often don't care: how much tap water is used for a toilet every year, and whether the toilet must be flushed with tap water? How much "dirty" soapy water is released when you brush your teeth, wash your face, and take a shower? Are they still useful? People are used to these "wastes" in public restrooms. According to investigations, in my country, what the family uses is mainly a flush toilet, while public toilets (such as schools, factories, public toilets, etc.) mainly use squatting pits. The flush toilet is based on the size of the water storage capacity of its water tank, and the water is released separately. There are 9 liters of direct release, 3/6 liters of grades and intelligent types; squatting urinals are divided into single pit and multiple pits. The multi-pit uses a unified large water tank with a water storage capacity of no more than 100 liters. There are several types of manual opening and discharging, timing opening and intelligent opening and discharging. But, no matter independent water tank, or unified large water tank, mostly directly flush with running water, like this, just wasted pure running water in vain. On weekdays, the water (soapy water) of the basin and the shower in the bathroom is directly discharged into the urban sewer pipes, and its utilization rate is almost zero. Therefore, it is necessary and worthwhile to use the toilet water instead of pure tap water to flush the toilet, which can not only improve the reuse rate of the sewage, but also save pure water resources.

Utility model content

The purpose of this utility model is to propose a water-saving toilet, which uses sewage to replace general flushing water, so as to save water resources and improve the utilization rate of sewage.

This water-saving toilet includes a toilet and a toilet water tank, and is characterized in that a water storage tank is arranged under the toilet, and the water storage tank is respectively connected with a drain port and the toilet water tank through pipes. A water pump is arranged at the joint between the water storage tank and the toilet water tank.

An electromagnetic valve is installed at the pipeline connected with the water outlet, and is connected with the controller.

A position sensor and a filter net are installed in the water storage tank, and the position sensor is connected with the controller.

A lever with a floating ball is arranged in the water tank of the toilet, and the tail end of the lever is partly exposed outside the box, and sensors connected with the controller are arranged up and down.

The water pump is connected with the controller.

The utility model is simple in structure and reasonable in design, and makes good use of the toilet flushing water instead of pure tap water, which can not only improve the reuse rate of the sewage, but also save pure water resources. Good market prospect.

Detailed ways

As shown in Figures 1 and 2, a water-saving toilet includes a toilet 1 and a toilet water tank 2, and is characterized in that a water storage tank 3 is arranged under the toilet 1, and the water storage tank 3 passes through a pipeline 41 And the pipeline 42 is connected with the water outlet 5 and the toilet water tank 2 respectively. A water pump 6 is arranged at the joint between the water storage tank 3 and the toilet water tank 2 .

The described pipeline 41 that is connected with the water outlet 5 is equipped with an electromagnetic valve 71 and an electromagnetic valve 72, both of which are connected with the controller 8.

A position sensor 9 and a filter screen 10 are installed in the water storage tank 3 , and the position sensor 9 is connected with the controller 8 .

The toilet water tank 2 is provided with a lever 11 with a floating ball, the tail end of the lever 11 is exposed outside the casing 2, and the sensor 121 and the sensor 122 connected with the controller 8 are arranged up and down.

The water pump 6 is connected with the controller 8 .

Under normal conditions, the electromagnetic valve 71 on the pipeline leading to the water storage tank 3 from the water outlet 5 is normally open, while the electromagnetic valve 72 leading to the drain pipe is normally closed, and the water flows directly into the water storage tank 3 through the water outlet 5 and passes through the filter screen. 10 Isolate the larger substances and perform a rough filtration of the water quality. When the water surface in the water storage tank 3 reached the height of the position sensor 9 in the water storage tank 3, the position sensor 9 notified the controller 8, and the controller 8 closed the electromagnetic valve 71 on the pipeline of the water storage tank 3 from the water outlet 5 to stop Water intake; and simultaneously open the electromagnetic valve 72 leading to the drain pipe, allowing the water to be directly discharged into the ground.

At this time, if there is water in the water tank 2 of the toilet, the floating ball drives the lever 11, so that the exposed tail end of the lever 11 touches the sensor 122 below, and the sensor 122 informs the controller 8 that the water tank 2 is full of water, and the water pump 6 is not started. Water is supplied in the water tank 2.

If there is no water in the toilet water tank 2, the floating ball drives the lever 11, so that the exposed end of the lever 11 touches the upper sensor 121, and the sensor 121 notifies the controller 8 that there is no water in the water tank 2, and then starts the water pump 6 to the water tank 2 Water is supplied inside until the floating ball in the water tank 2 makes the exposed position of the lever 11 touch the sensor 122 below.

After the water supply was completed, the water level in the water storage tank 3 dropped below the position sensor 9, and the position sensor 9 notified the controller 8 to open the water outlet 5 again to the electromagnetic valve 71 on the pipeline of the water storage tank 3, to enter the water storage tank 3, Close the solenoid valve 72 leading to the drain pipe simultaneously.

To sum up, such a repeated cycle can achieve the purpose of using sewage and saving water.

As described in Table 1, the water pump 6 will only start when the electromagnetic valve 71 is closed, the electromagnetic valve 72 is opened, the position sensor 9 has an induction, and the sensor 121 above the lever 11 has an induction. Water is supplied to the toilet tank 2 .

The utility model is simple in structure and reasonable in design, and makes good use of the toilet flushing water instead of pure tap water, which can not only improve the reuse rate of the sewage, but also save pure water resources. Good market prospect.
