[0030] Refer to Figure 1 , the embodiment of the present utility model provides a pet drinking fountain, which uses a water pump with a changeable flow direction. The specific structure of the water pump is as follows:

[0031] Refer to Figures 5 - 8 , in an optional embodiment, a water pump with a changeable flow direction includes a water pump mounting base 1 and a water pump body 2 detachably arranged on the water pump mounting base 1. A first socket 11 and a second socket 12 are arranged on the water pump mounting base 1, a plug 21 is arranged on the water pump body 2, and a first water inlet pipe 14 and a second water inlet pipe 16 are arranged on the water pump mounting base 1. When the first socket 11 is connected to the plug 21, the first water inlet pipe 14 actively intakes water; when the second socket 12 is connected to the plug 21, the second water inlet pipe 16 actively intakes water. When replacing the water pump body 2, it only needs to be pulled out, as Figure 5It is a structure for pulling out the water pump body 2. Just insert the new water pump body 2 into the installation hole of the water pump mounting seat 1. If it is necessary to change the water pumping direction of the water pump, just pull out the water pump body 2 and change the original plug 21 aligned with the first socket 11 to the plug 21 aligned with the second socket 12. The first water inlet pipe 14 and the second water inlet pipe 16 are respectively connected to different water inlet places.

[0032] Refer to Figures 7 - 8 , in an optional embodiment, a pump body 27 is provided on one side of the water pump body 2, and the other side is a hollow shell 26. The water pump mounting seat 1 is further provided with a first water outlet pipe 15 and a second water outlet pipe 17. When the pump body 27 corresponds to the first water inlet pipe 14 and the first water outlet pipe 15, the hollow shell 26 corresponds to the second water inlet pipe 16 and the second water outlet pipe 17. When the pump body 27 corresponds to the second water inlet pipe 16 and the second water outlet pipe 17, the hollow shell 26 corresponds to the first water inlet pipe 14 and the first water outlet pipe 15.

[0033] Specifically, an extension pipe cooperating with the first water inlet pipe 14, the first water outlet pipe 15, the second water inlet pipe 16 and the second water outlet pipe 17 is provided at the bottom of the water pump body 2. The first water outlet pipe 15 and the second water outlet pipe 17 can be one pipe. When water enters from the first water inlet pipe 14, water flows out from the water outlet pipe. When water enters from the second water inlet pipe 14, water also flows out from the water outlet pipe.

[0034] Of course, the first water outlet pipe 15 and the second water outlet pipe 17 can be two different pipes. The pump body 27 is the power for active water absorption. The position corresponding to the pump body 27 is the position for active water absorption. Whether the pipes corresponding to the hollow shell 26 are used depends on the actual situation. When the pipes of the hollow shell 26 are not used, when the pump body 27 corresponds to the first water inlet pipe 14 and the first water outlet pipe 15, water enters from the first water inlet pipe 14 and water flows out from the first water outlet pipe 15. If the pump body 27 corresponds to the second water inlet pipe 16 and the second water outlet pipe 17, water enters from the second water inlet pipe 16 and water flows out from the second water outlet pipe 17.

[0035] When the pipes of the hollow shell 26 are used, when the pump body 27 corresponds to the first water inlet pipe 14 and the first water outlet pipe 15, water enters from the first water inlet pipe 14 and water flows out from the first water outlet pipe 15, then water enters from the second water outlet pipe 17 and water flows out from the second water inlet pipe 16. When the pump body 27 corresponds to the second water inlet pipe 16 and the second water outlet pipe 17, water enters from the second water inlet pipe 16 and the second water outlet pipe 17, then water enters from the first water outlet pipe 15 and water flows out from the first water inlet pipe 14. A flow guiding seat 261 is provided on the hollow shell 26 for conducting the second water inlet pipe 16 and the second water outlet pipe 17. Water flows through the flow guiding seat 261 and will not flow into the pump body 27 to cause a short circuit.

[0036] Refer to Figure 5, in an optional embodiment, the first water inlet pipe 14, the first water outlet pipe 15, the second water inlet pipe 16 and the second water outlet pipe 17 are arranged in a row; the first water outlet pipe 15 and the second water outlet pipe 17 are arranged between the first water inlet pipe 14 and the second water inlet pipe 16, or the first water inlet pipe 14 and the second water inlet pipe 16 are arranged between the first water outlet pipe 15 and the second water outlet pipe 17. The cross-section of the water pump body 2 is in the shape of an annular runway, and the plug 21 is arranged on the side of the water pump body 2; the first socket 11 and the second socket 12 are symmetrically arranged on both sides of the water pump body 2. When it is convenient to change the direction of the water pump body 2, all positions can be aligned, which is convenient for changing the flow direction.

[0037] Refer to Figures 1 - 8 , when the water pump is specifically used in a pet drinking fountain, it can be used in combination with a filter element. There are two pipes at the bottom of the filter element, which are respectively connected to the first water outlet pipe 15 and the second water outlet pipe 17. The pet drinking fountain is provided with a clean water tank and a sewage tank. The first water inlet pipe 14 is connected to the clean water tank, and the second water inlet pipe 16 is connected to the sewage tank. The pipes, the water tanks and the filter element are all connected by water pipes 3. The first water inlet pipe 14, the first water outlet pipe 15, the second water inlet pipe 16 and the second water outlet pipe 17 are connected with water pipes 3.

[0038] When the water in the sewage tank enters the clean water tank, the pump body 27 corresponds to the first water inlet pipe 14 and the first water outlet pipe 15. The specific flow direction is: the water in the sewage tank enters from the first water inlet pipe 14, and the water flowing out from the first water outlet pipe 15 enters the filter element for filtration and then flows into the second water outlet pipe 17, reaches the inside of the hollow shell 26 from the second water outlet pipe 17, and then flows out from the second water inlet pipe 16 and enters the clean water tank.

[0039] When backwashing the filter element, the position of the pump body 27 is swapped. The pump body 27 corresponds to the second water outlet pipe 17 and the second water inlet pipe 16. The water in the clean water tank flows in from the second water inlet pipe 16, flows out from the second water outlet pipe 17 to wash the filter element, and the washed water flows into the hollow shell 26 from the first water outlet pipe 15, and then flows out from the first water inlet pipe 14 and enters the sewage tank.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
