[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1 to Figure 2 The figure is a schematic diagram of the structure of the first embodiment of the pet water dispenser of the utility model. The first embodiment of the pet water dispenser comprises: a water tank 1, a base 8, a protective cover 2, a nozzle 5, a water storage tray 3, a water outlet 4, a filter assembly 6, and a water pump 9. The base 8 is detachably arranged below the water tank 1, the filter assembly 6 is arranged in the water tank 1, the upper end of the filter assembly 6 is connected to the nozzle 5, the nozzle 5 is installed in the water storage tray 3, and the water storage tray 3 is provided with a water outlet 4.

[0027] In the first embodiment of the pet drinking fountain, the first part of the water pump 9 is arranged in the water tank 1, and the second part of the water pump 9 is arranged in the base 8 corresponding to the first part. That is, the pump body part of the water pump 9 is the first part, which is installed in the water tank 1, and the live part of the water pump 9 is the second part, which is installed in the base 8 corresponding to the pump body part. The pump body part and the live part of the water pump 9 can be separated. After the water tank 1 is removed from the base 8, the pump body part of the water pump 9 is naturally separated from the live part. The pump body part and the live part of the water pump 9 are arranged at intervals. Specifically, the pump body part and the live part of the water pump 9 are separated by the bottom plate 20 of the water tank 1 and the top plate 21 of the base 8, and the two realize force conduction through magnetic attraction.

[0028] Specifically, Figure 2 As shown, the first part of the water pump 9 includes a pump casing 19 and an impeller assembly rotatably disposed in the pump casing, wherein the pump casing 19 has a water inlet 15 and a water outlet, and water is pumped from the water inlet 15 of the pump casing to the water outlet of the pump casing 19 by rotating the impeller assembly.

[0029] like Figure 2 As shown, the second part includes a driving assembly, the driving assembly is provided with a first magnetic mechanism 12, and the impeller assembly is provided with a second magnetic mechanism 13.

[0030] The water pump 9 is configured to transmit the power provided by the driving assembly through the magnetic attraction force between the first magnetic mechanism 12 and the second magnetic mechanism 13 to rotate the impeller assembly.

[0031] The driving assembly includes a motor 10 and a rotating shaft 11 connected to the motor 10, the first magnetic mechanism 12 is arranged at the end of the rotating shaft 11, the impeller assembly includes an impeller shaft 14 and an impeller 22 arranged on the impeller shaft 14, the second magnetic mechanism 13 is arranged on the impeller 22, the rotating shaft 11 and the impeller shaft 14 are coaxially arranged, that is, the axis of the rotating shaft 11 overlaps with the axis of the impeller shaft 14, and the first magnetic mechanism 12 and the second magnetic mechanism 13 are matched so that a magnetic attraction force can be generated between the first magnetic mechanism 12 and the second magnetic mechanism 13.

[0032] In the first embodiment of the pet water dispenser, the first magnetic mechanism 12 extends radially along the rotating shaft 11. Specifically, the first magnetic mechanism 12 has a first magnetic attraction surface, and the second magnetic mechanism 13 has a second magnetic attraction surface. The first magnetic attraction surface is spaced and arranged to attract each other corresponding to the second magnetic attraction surface. The first magnetic attraction surface and the second magnetic attraction surface are both magnetic attraction planes. The magnetic attraction surface between the first magnetic mechanism 12 and the second magnetic mechanism 13, that is, the first magnetic attraction surface and the second magnetic attraction surface are both perpendicular to the axial direction of the rotating shaft 11. The first magnetic mechanism 12 and the second magnetic mechanism 13 are both flat magnetic mechanisms, and the first magnetic mechanism is vertically installed at the end of the rotating shaft.

[0033] Based on this planar configuration, the bottom plate 20 of the water tank 1 and the top plate 21 of the base 8 can be conventional flat plates without adaptability modification. The first magnetic mechanism 12 generates magnetic attraction force with the second magnetic mechanism 13 across the top plate 21 and the bottom plate 20 .

[0034] like Figure 2 As shown, the water pump 9 also includes a housing 18. In the first embodiment of the pet water dispenser, the housing 18 covers the entire pump housing 19. The housing 19 can be fixed to the bottom plate 20 by snapping. The housing 18 is provided with several water inlets 17, and the water inlets 17 can be made in the form of slits to facilitate the water in the water tank to enter the housing. The water inlet 17 of the housing 18 is connected to the water inlet 15 of the pump housing 19. A filter cotton 16 is provided between the water inlet 17 of the housing 18 and the water inlet 15 of the pump housing 19. The water in the water tank 1 enters the housing 18 through the water inlet 17 of the housing 18, enters the water inlet 15 of the pump housing 19 after being filtered by the filter cotton 16, and then centrifuges to the water outlet of the pump housing 19 by the rotation of the impeller.

[0035] like Figure 1As shown, in the first embodiment of the pet water dispenser, the water outlet of the pump housing 19 is connected to the inlet of the filter assembly 6 through the pipeline 7, wherein the pipeline 7 passes through the housing 18. It is also possible to change the positional relationship between the first part of the water pump and the filter assembly 6 so that the water outlet of the pump housing 19 is directly connected to the inlet of the filter assembly 6, and the pipeline 7 is omitted.

[0036] Example 2

[0037] like Figure 3 to Figure 4 The figure is a schematic diagram of the structure of the second embodiment of the pet water dispenser of the utility model. The second embodiment of the pet water dispenser has the same general structure as the first embodiment, and the main differences are: the first magnetic mechanism 12 extends along the circumference of the rotating shaft 11, the first magnetic attraction surface and the second magnetic attraction surface are both magnetic attraction cylindrical surfaces, and the magnetic attraction surface between the first magnetic mechanism 12 and the second magnetic mechanism 13, that is, the first magnetic attraction surface and the second magnetic attraction surface are both arranged around the axial direction of the rotating shaft. The first magnetic mechanism 12 and the second magnetic mechanism 13 are both cylindrical magnetic mechanisms, and the first magnetic mechanism 12 is sleeved outside the end of the rotating shaft. Based on the above configuration, the bottom plate 20 of the water tank 1 is provided with a groove, and correspondingly, the top plate 21 of the base 8 is provided with a protrusion, and the protrusion matches the groove. The end of the rotating shaft with the first magnetic mechanism 12 is provided in the protrusion, and the protrusion can be snapped into the groove. After the protrusion is installed in place, the second magnetic mechanism 13 is sleeved outside the first magnetic mechanism 12 with the side wall of the protrusion and the side wall of the groove separated, so that the first magnetic mechanism 12 and the second magnetic mechanism 13 match. Considering the installation of the motor and the impeller, and the snap connection between the protrusion and the groove, a two-step structure is also provided around the protrusion, and correspondingly, a matching two-step structure is also provided around the groove.

[0038] In addition, in the second embodiment of the pet water dispenser of the present invention, the housing 18 only covers the upper part of the pump housing 19 and the water inlet at the top of the pump housing 19, that is, it does not completely cover the pump housing 19. The present invention is not limited to this, and the shape and size of the housing 18 can be adjusted to match different forms of pump housings.

[0039] The setting position of the first magnetic mechanism can also be changed. For example, the first magnetic mechanism can be set as a cylindrical magnetic mechanism, and the second magnetic mechanism can be a cylindrical mechanism. The first magnetic mechanism is coaxially set at the end of the rotating shaft, that is, the axis of the first magnetic mechanism overlaps with the axis of the rotating shaft, and the second magnetic mechanism can be detachably mounted outside the first magnetic mechanism.

[0040] The beneficial effects of the water pump and the corresponding pet drinking fountain of the utility model are that the live part of the water pump and the pump body are creatively separated and arranged in the base and the water tank respectively, so that the live part of the water pump avoids contacting the water in the water tank. The design is ingenious, easy to use, easy to maintain, and reduces costs.

[0041] In this specification, the utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the utility model. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
