Description

Technical Field

[0001] The utility model relates to the technical field of pet products, in particular to a magnetically driven water pump and a pet drinking fountain. Background Art

[0002] Existing pet water dispenser pumps rely on pre-made pumps, which are expensive, especially wireless induction pumps. Wireless induction pumps operate by transmitting power through wireless induction coils, resulting in a complex structure and significant energy loss due to multiple energy conversions. Furthermore, the small size of pre-made pumps can lead to microbial growth in the water, creating a narrow gap between the rotors and causing clogging. Furthermore, cleaning the pump requires considerable operator skill.

[0003] In the current prior art, the patent with publication number CN109479743A provides an external magnetic cylindrical rotor, which is wrapped with a drive coil, i.e., an external magnetic rotor. Since the rotor is submerged in water during operation, it is easily contaminated by bacteria and impurities in the water. Therefore, regardless of whether it is an external magnetic rotor or an internal magnetic rotor, due to the annular magnetic gap, impurities will be thrown to the outer ring after the rotor rotates, so it is easy to be stuck by impurities over time. The structure of the internal magnetic or external magnetic rotor is relatively complex, and a convex or concave stage of the coil is required, which is also not conducive to cleaning. Utility Model Content

[0024] In order to better understand the technical solution of the present invention, the embodiments provided by the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-2As shown, it can be understood that the magnetically driven water pump provided in this embodiment includes: a multi-pole rotor 1, a plurality of drive coils 2 and a plurality of pump blades 3, wherein the pump blades 3 are evenly arranged on the multi-pole rotor 1 with the center of the multi-pole rotor 1 as the center of a circle; the multi-pole rotor 1 is disc-shaped and is arranged below the pump blades 3, and the corresponding plurality of drive coils 2 are arranged below the multi-pole rotor 1, and the pump blades 3, the multi-pole rotor 1 and the drive coils 2 are arranged in parallel from top to bottom; and a plurality of magnetic regions are provided on the multi-pole rotor 1.

[0027] In this embodiment, the water pump's driving function is achieved through a multipolar rotor 1, pump blades 3, and drive coils 2. Specifically, the multipolar rotor 1 is magnetized to achieve magnetic properties, with alternating positive and negative magnetic regions to form a multipolar magnetic field. The multipolar rotor 1 is a permanent magnet rotor. By energizing the corresponding plurality of drive coils 2, a magnetic field is formed, which drives the multipolar rotor 1 to rotate. The multipolar rotor 1, in turn, drives the pump blades 3, achieving drive. A special feature is that the multipolar rotor 1 is disc-shaped, in this embodiment, a circular disc. The pump blades 3, multipolar rotor 1, and drive coils 2 are arranged parallel from top to bottom, creating a butterfly-type water pump. The disc-shaped magnetic gaps are parallel. When the disc rotor rotates, it spins and ejects impurities from the gaps, making it less likely to become stuck. Furthermore, the parallel magnetic surfaces of the disc-shaped pump are easy to clean.

[0028] Furthermore, the drive coil 2 is disposed around a magnetic pole 4, which is mounted on a magnetic body 5. Both the magnetic pole 4 and the magnetic body 5 are made of a magnetically conductive material. The drive coil 2 contains a magnetic pole 4 made of a magnetically conductive material, and the lower portion of the magnetic pole 4 is connected to the magnetic body 5 to form a magnetic circuit. The magnetic body 5 serves to increase the efficiency of the coil in generating a magnetic field.

[0029] Furthermore, the magnetic poles 4 are provided with deflection bosses 6, which are located to the left or right of the magnetic poles 4. Each magnetic pole 4 is provided with a magnetic deflection boss 6, positioned to the left or right of the magnetic pole. After the drive coil 2 is deenergized, it guides the multipolar rotor 1 to deflect to its stop position, facilitating easier rotor startup the next time. Because a disc-shaped rotor at its equilibrium midpoint is difficult to start after the drive coil 2 is energized, potentially causing a failure to start, this embodiment provides a deflection boss 6 on each magnetic pole 4. The deflection boss 6 is located to the left or right of the magnetic pole (the deflection boss 6 is positioned in the direction of rotation; for clockwise rotation, the deflection boss 6 is to the left; for counterclockwise rotation, the deflection boss 6 is to the right). With these deflection bosses 6, the multipolar rotor 1 automatically deflects from its stop position, disrupting the magnetic field balance and significantly facilitating startup.

[0030] In this embodiment, a pump housing 7 is further included. The pump blades 3 and the multipolar rotor 1 are both disposed within the pump housing 7. A pump shaft 8 is disposed in the middle of the multipolar rotor 1. A shaft sleeve 9 is disposed on the outside of the pump shaft 8. The pump blades 3 are secured to the multipolar rotor 1 via the pump shaft 8. The pump housing 7 is used to accommodate part of the structure that drives the water pump. The provision of the shaft sleeve 9 on the outside of the pump shaft 8 reduces wear and allows the multipolar rotor 1 to operate more smoothly.

[0031] Example 2

[0032] like Figure 3-4 As shown, this embodiment provides a pet drinking fountain, comprising a housing 10, a drinking bucket 11, and any of the magnetically driven water pumps described above, wherein the drinking bucket 11 is disposed within the housing 10. The magnetically driven water pump is disposed within the pet drinking fountain and is used to pump water in the drinking bucket 11 to a drinking port for the pet to drink.

[0033] Furthermore, the pump blades 3 and multi-pole rotor 1 are disposed within the water tank 11, while the drive coil 2, magnetic poles 4, and magnets 5 are disposed outside the water tank 11. The pump blades 3 and multi-pole rotor 1 are disposed within the water tank 11 to pump water through the rotation of the pump blades 3 during startup, while the drive coil 2, magnetic poles 4, and magnets 5 need to be isolated from the liquid and connected to an electrical device.

[0034] Furthermore, the pump housing 7 is provided with a water inlet 12 and a water outlet 13; the water inlet 12 is communicated with the drinking water bucket 11 and is arranged above the pump blade 3; the water outlet 13 is communicated with the accommodating space where the pump blade 3 is located.

[0035] The water inlet 12 in this embodiment is used to input the water in the drinking bucket 11 into the driving device, and the water is pumped to the water outlet 13 through the pump blade 3. The water outlet 13 then transports the water to the drinking port through the connecting water pipe for the pet to drink.

[0036] The above is a detailed introduction to a magnetically driven water pump and a pet drinking fountain provided by an embodiment of the present invention. For those skilled in the art, according to the ideas of the embodiment of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
