Description

Technical Field

[0001] The utility model relates to a water-saving device for public toilets, in particular to a device for using the drainage of a wash basin of a public toilet for flushing a toilet, and belongs to the technical field of water resource recycling. Background Art

[0002] During the use of public toilets, the drainage from the wash basin is usually discharged directly, resulting in a waste of water resources. At the same time, in order to keep the toilet clean and hygienic, the toilet needs to be flushed regularly. Therefore, how to effectively recycle and utilize the drainage from the wash basin while ensuring the water quality for flushing the toilet is an important issue in water conservation in public toilets. Summary of the invention

[0003] The utility model aims to provide a public toilet water-saving device, which can use the drainage of the wash basin of the public toilet for flushing the toilet, and has the functions of sedimentation, filtration, disinfection and sterilization to ensure the water quality.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A water-saving device for a public toilet comprises a water reservoir, a connecting box and a water storage tank. The drainage pipe of the public toilet wash basin is connected to the water reservoir, and the upper side wall of the water reservoir is connected to the connecting box through a connecting pipe. When the water level of the clean water in the upper part of the water reservoir reaches the height of the inlet of the connecting pipe, the clean water enters the connecting box through the connecting pipe. The connecting box is connected to the water storage tank through a pipeline provided with a water pump, and the water storage tank is placed above the toilet water tank and connected to the toilet water tank through a pipeline. An ultraviolet lamp for disinfection and sterilization is provided inside the toilet water tank.

[0006] The utility model of the public toilet water-saving device realizes the recycling of wastewater by introducing the drainage of the wash basin into the water storage tank. The water storage tank has a sedimentation effect and can remove impurities and suspended matter in the wastewater. The connecting box and the water storage tank form a connecting vessel effect. When the liquid level of the water storage tank is high, the upper layer of clean water is smoothly sent to the connecting box. The water storage tank draws water from the connecting box through a water pump. When the liquid level gauge of the water storage tank shows that there is enough water, the water inlet of the toilet water tank is switched from tap water to the water storage tank. An ultraviolet lamp is arranged in the toilet water tank to fully disinfect and sterilize in a small space, avoiding air pollution caused by water mist caused by flushing.

[0007] Specifically, the utility model also includes the following technical solutions:

[0008] A filter unit is provided in the middle of the drain pipe to further remove impurities and suspended matter in the wastewater. The filter unit includes a cylinder with openings at both ends, an opening is provided on the middle side wall of the cylinder, a filter screen is provided inside the opening between the two ends of the cylinder, and a detachable plug for fixing the filter screen is provided at the opening. In this way, the filter screen can be easily replaced and cleaned to ensure the filtering effect.

[0009] A valve is provided in the middle of the connecting pipe so as to close the connecting pipe when the water tank is pumping water, thereby preventing the strong suction force from disturbing the sediment at the bottom of the reservoir and causing the sewage with sediment to float up into the connecting box.

[0010] Several baffles are set on the water inlet side of the reservoir to form a tortuous flow path to prevent the incoming water from disturbing the sediment at the bottom of the reservoir. This can increase the water flow resistance, slow down the water flow speed, make the sediment stay in the flow path longer, and improve the sedimentation effect.

[0011] The water tank is equipped with a liquid level meter to monitor the water level in the water tank in real time and replenish water or stop pumping in time.

[0012] Through the above technical solution, the utility model of the public toilet water-saving device can effectively use the drainage of the wash basin for flushing the toilet, while ensuring the stability of water quality and water volume. In addition, the utility model also has the advantages of simple structure, convenient operation, low maintenance cost, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model;

[0014] Figure 2 is a schematic diagram of the structure of the filtration unit; Implementation

[0015] The utility model is described in detail below with reference to the accompanying drawings and embodiments. Example

[0016] like Figure 1 As shown, the public toilet water-saving device of the utility model comprises a water reservoir 1, a connecting box 2 and a water storage tank 3. The drain pipe of the public toilet wash basin 4 is connected to the water reservoir 1. The upper side wall of the water reservoir 1 is connected to the connecting box 2 through a connecting pipe 5. When the water level of the clean water in the upper part of the water reservoir 1 reaches the inlet height of the connecting pipe 5, the clean water enters the connecting box 2 through the connecting pipe 5. The connecting box 2 is connected to the water storage tank 3 through a pipeline provided with a water pump 6. The water storage tank 3 is placed above the toilet water tank 7 and is connected to the toilet water tank 7 through a pipeline. An ultraviolet lamp 8 for disinfection and sterilization is provided inside the toilet water tank 7.

[0017] Before using the utility model, the wash basin drainage pipe of the public toilet is first connected to the water reservoir. Then, the water reservoir is connected to the connecting box through a connecting pipe. When the wash basin is used, waste water will flow into the water reservoir and naturally settle therein.

[0018] When the water level in the reservoir reaches the height of the connecting pipe inlet, clean water will enter the connecting box through the connecting pipe. At this time, the water pump starts to transport the clean water in the connecting box to the water storage tank through the pipeline.

[0019] When the water level in the water storage tank reaches a certain height, the water in the water storage tank can be injected into the toilet water tank through the pipeline. At this time, the ultraviolet lamp inside the toilet water tank is started to disinfect and sterilize the injected water.

[0020] When you need to flush the toilet, you only need to open the water inlet valve of the toilet tank, and the water in the water storage tank will flow into the toilet tank through the pipe, thus completing the flushing process of the toilet. Example

[0021] On the basis of Example 1, the utility model also includes the following technical solutions: a filter unit 9 is provided in the middle of the drain pipe. The filter unit 9 includes a cylinder 10 with openings at both ends, an opening is provided on the middle side wall of the cylinder 10, a filter screen 11 is provided inside the opening and located between the two ends of the cylinder 10, and a detachable plug 12 for fixing the filter screen is provided at the opening. In this way, the filter screen can be easily replaced and cleaned to ensure the filtering effect. Example

[0022] On the basis of embodiment 2, the utility model also includes the following technical solution: a valve 14 is provided in the middle of the connecting pipe. In this way, the connecting pipe can be closed to prevent waste water from entering the connecting box. Example

[0023] On the basis of Example 1, the utility model also includes the following technical solution: a plurality of baffles 15 are arranged on the water inlet side of the water reservoir, and the baffles 15 form a tortuous flow channel 16 to prevent the inlet water from disturbing the sediment at the bottom of the water reservoir. This can increase the water flow resistance, slow down the water flow speed, make the sediment stay in the flow channel for a longer time, and improve the sedimentation effect. Example
