In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the drawings and examples.
It should be understood that the specific embodiments described herein are used only to illustrate the present invention and are not used to limit the present invention.

1 to 8, an embodiment of the present invention provides a water dispenser for a smart pet, and includes a control device, a purified water tank 1, a waste water tank 2, a purified water tank 3, and a main body case 4. The purified water tank 1, the waste water tank 2, and the drinking water tray 3 are each detachably mounted on the main body case 4.
When tank 1 is removed to supply water, the purified water tank is divided into a first purified water tank 1A and a second purified water tank 1B to ensure the total purified water volume while avoiding the excessive weight of a single tank.

3 to 6, the drinking water tray 3 is provided with a fountain nozzle 301, a wash water outlet 302, and a waste water recovery hole 305, and the fountain nozzle 301 is provided with a drinking water outlet 301A.
The purified water tank 1A and the purified water tank 1B are each provided with a water outlet (not shown), which is connected to a drinking water outlet 301A and a washing water outlet 302 via a purified water passage.
The purified water passage includes a main body purified water passage (not shown) provided in the main body case 4 and a drinking water tray purified water passage 303 provided in the drinking water tray.

There is further provided a “purified water flow drive device 5 ” for driving the water flow in the purified water passage, and the purified water flow drive device 5 includes an electromagnetic valve 501 , a drinking water supply pump 502 , and a washing water supply pump 503 .
The operating principle of the purified water flow drive device 5 is as follows: the purified water in the purified water tank 1A and the purified water tank 1B flows out from their outlets and then flows into the corresponding solenoid valves 501. The solenoid valves 501 are turned on, and the purified water continues to flow into the drinking water tray purified water passage 303. The purified water is then driven by the drinking water supply pump 502 and the washing water supply pump 503 to flow into the drinking water outlet 301A and the washing water outlet 302, respectively.
Since there is a large step between the purified water tank 1 and the drinking water tray 3, when the solenoid valve 501 is turned on, the purified water in the tank 1 flows directly into the drinking water outlet 301A and the washing water outlet 302 by gravity. The main power function of the drinking water supply pump 502 and the washing water supply pump 503 is to control the corresponding flow rate, and the configuration example of the purified water flow drive device 5 provided in this embodiment can greatly reduce the mechanical power demand of the water flow in the purified water passage, reduce energy consumption, and also reduce the noise during operation of the power device.

3, 4, 5 and 8, the drinking water tray 3 is provided with a drinking water area 3A and a waste water area 3B spaced apart from each other, the waste water collection hole 305 connects the drinking water area 3A and the waste water area 3B, the bottom of the waste water area 3B is lower than the bottom of the drinking water area 3A, and the drinking water accumulated in the drinking water area 3A can be directly drained into the waste water area 3B by the step.
The wastewater passage includes a main body wastewater passage (not shown) provided in the main body case 4 and a "drinking water tray wastewater passage 304" provided in the drinking water tray 3, one side of which is connected to the main body wastewater passage and the other side of which is connected to the wastewater area 3B.

A "wastewater flow drive device" for driving the water flow in the wastewater channel is further provided, and the drive device is preferably a "diaphragm pump 6". The operation principle of the wastewater flow drive device is as follows.
When the amount of water accumulated in the wastewater area 3B of the drinking water tray 3 reaches a preset value, the diaphragm pump 6 starts up, driving the wastewater in the wastewater area 3B into the drinking water tray wastewater passage 304, and then through the main body wastewater passage again, it flows into the wastewater tank 2 via the wastewater tank inlet 201.

The controller (not shown) is for controlling the on/off of the "wastewater flow drive device" and the "purified water flow drive device 5".
In order to ensure that the outline of the structure is clear, the specific structure of the clean water passage and the partial structure of the waste water passage are not shown in the drawings, and the partial structures are general pipe connections.

The wastewater area 3B is provided as a buffer area before the wastewater from the drinking water tray 3 flows into the wastewater passage. Any water that accumulates in the drinking water area 3A, whether it is drinking water or washing water, can be immediately discharged into the wastewater area 3B. When pets drink water, they can drink highly clean drinking water. The wastewater area 3B also provides a certain intermittent space for the frequency of wastewater discharge, ensuring that the frequency of discharge is more reasonable.

The beneficial effect of this embodiment is that, through the combined installation of the cleaning water outlet 302 and the waste water recovery hole 305, it achieves the independent function of cleaning the bottom of the drinking water tray 3, which, compared with the prior art, not only realizes regular drainage of the puddle of the drinking water tray 3, but also cleans the bottom of the drinking water tray 3 when draining the puddle, ensuring the cleanliness of the drinking water tray 3 and improving the cleanliness of pet drinking water.

In a limited embodiment, the purified water flow drive device 5 is an electrical component, while the purified water passage 303 of the drinking water tray is a non-electrical component, the purified water passage 303 of the drinking water tray is a closed passage structure, the pump bodies of the drinking water supply pump 502 and the washing water supply pump 503 are located on the outer periphery of the purified water passage 303 of the drinking water tray, and the suction fans (not shown) of the drinking water supply pump 502 and the washing water supply pump 503 enter the purified water passage 303 of the drinking water tray to drive the flow of the corresponding water flow.

3 to 5, in order to meet the needs and preferences of different pets regarding the height of drinking water, three drinking water areas are provided according to height, namely drinking water area 3A1, drinking water area 3A2 and drinking water area 3A3.
