[0020] In order to better understand the technical solutions of the present utility model, the embodiments provided by the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1

[0022] As Figure 2 shown, it can be understood that a magnetic pump impeller driving device provided in this embodiment includes: a multi-pole rotor 1, a plurality of pump impellers 2, and a coil group 3.

The pump frame 4 has an accommodation space, and a transmission shaft 5 is provided in the accommodation space. The multi-pole rotor 1 and the pump impeller 2 are both arranged on the transmission shaft 5 and are arranged with the transmission shaft 5 as the center; the multi-pole rotor 1 and the pump impeller 2 are both arranged on the pump frame 4.

[0023] In this embodiment, the driving function of the driving device is realized by the multi-pole rotor 1, the pump impeller 2, and the coil group 3. Specifically, the multi-pole rotor 1 is in a disc shape and is magnetized to achieve magnetism, and the magnetic regions are alternately positive and negative to form a multi-pole magnetic field. The multi-pole rotor 1 is a permanent magnetic rotor. The special feature is that a pump frame 4 is provided, and the multi-pole rotor 1 and the pump impeller 2 are both arranged on the pump frame 4 and are connected by a transmission shaft 5. Compared with the prior art where the transmission shaft 5 is directly arranged at the bottom of the product, in this embodiment, the transmission shaft 5 is suspended by the pump frame 4 and does not directly contact the external product, reducing noise, and a dedicated rotor space is formed between the pump frame 4 and the product, making the multi-pole rotor 1 operate more smoothly without obstacles.

[0024] Below the multi-pole rotor, a coil group 3 is provided. In this embodiment, it is a multi-stage coil with six pairs of positive and negative poles arranged at intervals. The coil group 3 complies with the working principle of a brushless motor and is equipped with a brushless motor drive. During operation, the brushless drive energizes the multi-stage coil according to the drive rule to form a rotating magnetic field. The rotating magnetic field drives the multi-pole rotor and the pump impeller 2, causing the multi-pole rotor and the pump impeller 2 to rotate around the transmission shaft 5. The rotation of the pump impeller 2 drives the water to generate centrifugal force to achieve the function of pumping water. In other embodiments, the coil group 3 can be set to four pairs of coils, eight pairs of coils, etc., as long as the above functions can be achieved.

[0025] Furthermore, a shaft sleeve is also provided in the accommodating space of the pump bracket 4. The shaft sleeve is arranged outside the transmission shaft 5. By setting the shaft sleeve, wear is reduced and the rotor runs more smoothly.

By distributing magnetic powder in the plastic material and then magnetizing it to achieve magnetism, and the magnetic regions are alternately positive and negative to form a multi-pole magnetic field.

[0027] Even further, a pump housing 7 is further included. The multi-pole rotor 1, the pump impeller 2, and the pump bracket 4 are all arranged inside the pump housing 7. The pump housing 7 is used to accommodate the multi-pole rotor 1, the pump impeller 2, and the pump bracket 4, making them suspended and separated from the bottom of the product to form a certain space to reduce noise.

The drinking water bucket 9 is arranged inside the housing 8, and the magnetic pump impeller drive device is arranged at the bottom of the drinking water bucket 9. The magnetic pump impeller drive device is arranged at the bottom of the drinking water bucket 9 of the pet drinking fountain. The rotation of the pump impeller 2 drives the water to generate centrifugal force to achieve the function of pumping water.
