[0045] In the above technical solution of the utility model, in order to ensure the normal use of the split water pump, in actual application, after the above water storage tank is mounted on the base, the raised portion of the water storage tank can be correspondingly inserted into the receiving hole of the base; at this time, the operator can set a magnetic component, such as a permanent magnet, in the receiving cavity of the above raised portion to serve as a rotor; and set an electromagnetic component, such as an electromagnet, at a position close to the receiving hole on the base to serve as a stator.

[0046] Based on this design, when the electromagnet is energized, it can generate a magnetic field. The magnetic component can rotate around its own rotor axis under the influence of the magnetic field, thereby driving the impeller connected thereto to rotate, thereby driving the fluid to move.

[0047] Furthermore, in the pet drinking fountain described in the utility model, the rotor assembly also includes a base, which is detachably arranged in the water storage tank, and a water inlet trough with a side opening is provided on the base, and an impeller is provided in the base, and the impeller is connected to the magnetic part; wherein, a drain outlet is also provided on the base, and a water pipe is provided at the drain outlet, and the water pipe is connected to the water inlet of the drinking trough.

[0048] Furthermore, in the pet drinking fountain described in the utility model, a mounting wall is provided in the water tank, a bayonet is provided on the mounting wall, a clip is provided on the base, and the clip corresponds to and matches the bayonet so that the water tank is engaged and connected with the base.

[0049] In the above technical solution of the utility model, in actual application, in order to ensure that the rotor assembly can be effectively installed at the corresponding position in the water storage tank, the rotor assembly can also be provided with a base to be connected to the water storage tank through the base, for example, Figure 4 and Figure 8 As shown, in some embodiments, a bayonet may be provided on a mounting wall in the water tank, and a clip may be provided on the base of the rotor assembly, so that the water tank and the base are snap-connected by matching the clip with the bayonet.

In order to prevent the water tank from tipping over, the peripheral wall of the water tank extends from the lower bottom surface of the water tank toward the base by no less than 15 mm.

[0061] At the same time, in this embodiment, two positioning holes are provided on the upper surface of the base, and the lower bottom surface of the water tank is provided with two positioning columns corresponding to the two positioning holes, so that when the water tank is mounted on the base, the two positioning columns are correspondingly inserted into the two positioning holes, thereby enhancing the installation stability of the water tank.

[0062] Accordingly, see further Figure 5 and Figure 7 It can be seen that in this embodiment, the upper surface of the above-mentioned base is also provided with a receiving hole, and the lower bottom surface of the above-mentioned water storage tank is provided with a protrusion corresponding to the receiving hole, and the protrusion is provided with a receiving cavity connected to the inner cavity of the water storage tank.

Based on this design, when the electromagnet is energized, it can generate a magnetic field, and the magnetic part can rotate around its own rotor axis under the influence of the magnetic field. The rotation of the magnetic part can drive the impeller connected to it to rotate, thereby driving the fluid in the water storage tank to move.

[0064] In addition, if Figure 3 , Figure 4 and Figure 5 As shown, the designed rotor assembly also includes a base, and a mounting wall is also provided in the water tank, and a bayonet is opened on the mounting wall.
