[0042] The present application provides an animal drinking device.

[0043] It can be understood that animals, especially pet cats, like to drink flowing water. In existing drinking equipment, a water pump is generally used to drive the drinking water to flow, and in order to keep the drinking water clean, the lower water outlet of the drinking tray in one of the animal drinking devices is located at the lowest point. When the drinking water flows into the lower water outlet, a vortex will be generated on the drinking tray. When the water pump loses power, all the drinking water will flow into the water tank through the lower water outlet, and the drinking tray will not store drinking water, which will cause the pet to be unable to drink water.

[0044] In order to solve the above technical problems, the technical scheme of the present application limits the water storage cavity for storing water by using a water storage tank, and the driving assembly of the water pump drives the water pumping assembly to rotate to flow the water in the water storage cavity to the drinking tray through the water guide pipe for the animal to drink. The control system is connected with the driving assembly to ensure that the driving assembly always gets power, thereby ensuring that the drinking tray always has drinking water for the pet to drink. Specifically, the driving assembly is connected with the first power supply end and the second power supply end, the first power supply end is also used to connect an external power supply, and the second power supply end is connected with a lithium battery. When the first power supply end loses power, the control unit controls the battery switch to be closed, so that the lithium battery supplies power to the driving assembly. In this way, the driving assembly can continue to use the lithium battery as a power supply when the external power supply is powered off. Therefore, the driving assembly can always get power to drive the water to flow to the drinking tray for the animal to drink.

[0045] The above technical solutions will be described in detail below in combination with the drawings.

[0046] In the embodiments of the present application, as shown in FIGS. 1-8, the animal drinking device comprises a water storage tank 100, a drinking tray 200, a water guide pipe 700, a water pump 300, and a control system 400. The water storage tank 100 defines a water storage cavity with a first opening 110. The drinking tray 200 is arranged at the first opening 110 and defines a drinking cavity with a second opening 210. The drinking tray 200 is further provided with a water outlet hole 230 and a water outlet hole 220. The water outlet hole 220 is arranged at the bottom of the drinking cavity, and the water outlet hole 230 is arranged at the cavity wall of the drinking cavity. The water outlet hole 230 is higher than the water outlet hole 220. The water guide pipe 700 is connected to the water storage tank 100 and the water outlet hole 230. The water pump 300 comprises a pump water assembly 310 and a driving assembly (not shown in the figure). The driving assembly comprises a stator and a coil winding, which surrounds the stator. The driving assembly is used to drive the pump water assembly 310 to rotate, so that the water in the water storage tank 100 flows to the drinking tray 200 through the water guide pipe 700. The control system 400 comprises a first power supply end 410, a second power supply end 420, a battery switch 430, a lithium battery 440, and a control unit 450. One end of the first power supply end 410 is electrically connected to the driving assembly, and the other end of the first power supply end 410 is connected to an external power supply 460. One end of the second power supply end 420 is electrically connected to the driving assembly, and the other end of the second power supply end 420 is electrically connected to the lithium battery 440 through the battery switch 430. The battery switch 430 is electrically connected to the control unit 450. When the first power supply end 410 is in a power-off state, the control unit 450 controls the battery switch 430 to close, so that the lithium battery 440 supplies power to the driving assembly.

[0047] In the specific implementation process, the water storage tank 100 forms a water storage cavity inside, which is used to store drinking water. The top of the water storage tank 100 is provided with a first opening 110, so that the water storage cavity is in communication with the outside through the first opening 110. The drinking tray 200 is installed at the first opening 110, and pets drink water from the drinking tray 200. The second opening 210 is arranged at the top of the drinking tray 200, and pets drink water from the drinking tray 200 through the second opening 210. In the embodiments, the drinking tray 200 has a drinking cavity for storing water. Specifically, the drinking tray 200 comprises a tray surface 240 and a side wall 250 arranged around the tray surface 240. The tray surface 240 and the side wall 250 jointly form a drinking cavity. The water outlet hole 220 is arranged at the lowest part of the tray surface 240, so that all the water in the drinking tray 200 can be discharged through the water outlet hole 220. The drinking tray 200 does not store water, which ensures the cleanliness of the water.

[0048] The water guide pipe 700 connects the water storage tank 100 and the water tray 200, so that the water in the water storage cavity flows into the water cavity through the water guide pipe 700; of course, the driving assembly drives the water pump assembly 310 to rotate, and then drives the water to flow. Further, the water outlet hole 230 of the water tray 200 is located on the side wall, the water inlet hole 220 is located on the bottom of the water cavity, and the horizontal height of the water outlet hole 230 is higher than that of the water inlet hole 220. The water flows out of the water outlet hole 230 to the water cavity, and is discharged from the water inlet hole 220 to the water storage cavity. It should be noted that in the embodiment, the water is discharged from the water outlet hole 230 along the circumferential direction of the water tray 200, and under the action of gravity, the process of water flowing from the water outlet hole 230 into the water tray 200 and flowing out of the water inlet hole 220 forms a vortex on the water tray 200. One end of the water guide pipe 700 is connected with the water outlet hole 230, and the other end is connected with the water pump 300. The water pump 300 drives the water in the water storage tank 100 to flow into the water outlet hole 230 through the water guide pipe 700. Further, the driving assembly of the water pump 300 drives the water pump assembly 310 to rotate, and then the water in the water storage cavity flows to the water tray 200 through the water guide pipe 700 and the water outlet hole 230. The water in the water tray 200 flows to the water storage cavity through the water inlet hole 220, thereby realizing the circulation of the water.

[0049] The control system 400 is used to control the power supply for the driving assembly. Specifically, as shown in FIG. 8, the control system 400 has two power supply lines. One of the power supply lines is connected with the external power source 460 (such as a mains power supply) through the first power supply end 410, that is, the external power source 460 is used to supply power for the driving assembly. The other power supply line is connected with the lithium battery 440 through the second power supply end 420, that is, the lithium battery 440 is used to supply power for the driving assembly. It should be noted that in the general state, the driving assembly is powered by the external power source 460. When the external power source 460 is powered off, the lithium battery 440 is controlled by the control unit 450 to supply power for the driving assembly. It can be understood that the second power supply end 420 is connected with the lithium battery 440 through the battery switch 430. The battery switch 430 is in a normally open state. The battery switch 430 is controlled by the control unit 450 to be closed, so that the lithium battery 440 is in communication with the circuit of the driving assembly, and power supply is realized. In this way, in the case of power failure, the driving assembly can still obtain electric energy through the lithium battery 440, and then continuously drive the water pump assembly 310 to rotate to drive the water to flow, so that the water tray 200 always has drinking water for animals to drink.

[0050] In the embodiment, the control system 400 further comprises a detection unit 470, one end of the detection unit 470 is electrically connected with the first power supply end 410, and the other end of the detection unit 470 is electrically connected with the control unit 450, and the detection unit 470 is configured to detect whether the first power supply end 410 is in a power-off state. In one aspect, when the detection unit 470 detects that the first power supply end 410 is in a power-off state, a first control signal is generated and sent to the control unit 450, and after the control unit 450 receives the first control signal, the battery switch 430 is controlled to be closed, and the lithium battery 440 is in electrical connection with the driving assembly circuit. In another aspect, the control unit 450 is configured to control the battery switch 430 to be opened when the first power supply end 410 is not in a power-off state. It can be understood that when the detection unit 470 detects that the first power supply end 410 is not in a power-off state, a second control signal is generated and sent to the control unit 450, and after the control unit 450 receives the second control signal, the battery switch 430 is controlled to be opened, and the lithium battery 440 is disconnected with the driving assembly circuit, and at the same time, the driving assembly is powered by the external power supply 460.

[0055] The water flowing to the overflow tray 500 is discharged from the first through hole 510 which is arranged at the bottom of the overflow tray 500 to avoid water retention. One end of the connecting portion 260 is connected to the bottom surface of the drinking tray 200, and the other end is a free end extending towards the overflow tray 500.
