Description

Technical Field

[0001] This utility model relates to the field of pet water dispenser pump technology, and in particular to a split-type pet water dispenser pump assembly. Background Technology

[0002] Pets are creatures kept by people for spiritual purposes rather than economic purposes. Traditionally, pets refer to mammals or birds, kept for enjoyment and companionship. In real life, pets include cats, dogs, fish, reptiles, amphibians, insects, and even plants, kept for viewing, companionship, and relieving people's mental stress.

[0003] To make drinking water more convenient for pets, smart pet water fountains are commonly used. A smart pet water fountain mainly consists of the following parts: a water tank, a water pump, a heating system, a filter, and a sensor. In this process, the water pump is the device that delivers water from the storage tank to the water bowl. Because the water pump works frequently, it has certain requirements. Using a smart pet water fountain is not only worry-free and labor-saving, but also ensures the cleanliness of the water source and the health of the pet. At the same time, it improves the pet's drinking experience and quality of life through technological means.

[0004] Currently, pet water fountain pumps on the market lack filtration functions and pose a risk of electric leakage. Even a weak current can harm small, electric-sensitive pets, and may even cause stress reactions, affecting their health and drinking behavior. Some pets may develop a fear of water fountains due to electric shocks and dare not approach them to drink.

[0005] Therefore, it is necessary to provide a split-type pet water dispenser pump assembly to solve the above-mentioned technical problems. Utility Model Content

[0046] Second embodiment

[0047] Please refer to the following: Figures 4-5 , Figure 4A schematic diagram of the second embodiment of the split-type pet water dispenser pump assembly provided by this utility model; Figure 5 This utility model provides a structural schematic diagram of a support spring. Based on the split-type pet water dispenser pump assembly provided in the first embodiment of this application, the second embodiment of this application proposes another split-type pet water dispenser pump assembly. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0048] Specifically, the difference in the split-type pet water dispenser pump assembly provided in the second embodiment of this application is that a fixing block 8 is fixedly connected to the opposite side of the outer surface of the fixing ring 4, a through fixing hole 7 is opened on the top of the fixing block 8, and a buckle 10 is fixedly connected to the opposite side of the inner surface of the fixing ring 4.

[0049] The fixing hole 7 is for easy passage of bolts to fix the fixing ring 4 in the corresponding position. The inner diameter of the fixing ring 4 allows the centrifugal pump assembly 2 to pass through. The two buckles 10 have openings on opposite sides to facilitate the rotation and insertion of the locking block 9. The buckles 10 have a certain length to increase the friction between the locking block 9 and the buckles 10, thereby increasing the connection stability.

[0050] The bottom of the mounting plate 1 is fixedly connected to four support springs 11 by four fixing plates 12, and the bottom ends of the four support springs 11 are fixedly connected to mounting plates 13 by fixing plates 12.

[0051] The mounting plate 13 is located inside the connecting ring 6, and the support spring 11 provides support force.

[0052] The bottom end of the mounting plate 13 is rotatably connected to the base plate 5 via a rotating buckle 14. The top of the base plate 5 is fixedly connected to the outer surface with a connecting ring 6. The inner surfaces of the connecting ring 6 are fixedly connected to opposite sides with locking blocks 9.

[0053] The top of the card block 9 is flush with the top of the connecting ring 6. The chassis 5 can rotate as needed. If necessary, the outer surface of the chassis 5 is provided with anti-slip texture.

[0054] Compared with related technologies, the split-type pet water dispenser pump assembly provided by this utility model has the following advantages:

[0055] Beneficial effects:

[0056] To facilitate the assembly and disassembly of the centrifugal pump assembly 2 on the mounting plate 1, four support springs 11 are installed at the bottom of the mounting plate 1 via four fixing plates 12. The mounting plate 13 is then connected to the four support springs 11 via the fixing plates 12. Simultaneously, the mounting plate 13 is installed on the top of the chassis 5 via a rotating buckle 14, allowing the chassis 5 to be freely adjusted in angle. A connecting ring 6 with two locking blocks 9 is installed on the top of the chassis 5. The locking blocks 9 and the buckle 10 engage to enable quick assembly and disassembly of the centrifugal pump assembly 2 on the mounting plate 1. In actual use, first, the fixing ring 4 is fixed in the corresponding position via the fixing blocks 8 and bolts. Then, the structure on the chassis 5 is connected to the mounting plate 1. After that, it is only necessary to... Centrifugal pump assembly 2 passes through the fixing ring 4, allowing two locking blocks 9 to engage from one side of the opening of the buckle 10, thus installing the centrifugal pump assembly 2. During this process, the mounting plate 1 will come into contact with the structure of the mounting fixing ring 4. In order for the locking blocks 9 to engage in the buckle 10, the support spring 11 will be compressed. After the locking blocks 9 are engaged, the support spring 11 provides support force to increase the connection stability. When it is necessary to disassemble the centrifugal pump assembly 2, simply rotate the chassis 5 in the opposite direction to disengage the locking blocks 9 from the buckle 10, and the centrifugal pump assembly 2 can be easily disassembled. This design can avoid the fasteners from being corroded by prolonged immersion in water, thereby reducing the difficulty of disassembly and maintenance of the centrifugal pump assembly 2 in the later stages.
