Description

Technical Field

[0001] This utility model belongs to the field of pet supplies, and specifically relates to an automatic pet water dispenser. Background Technology

[0002] With more and more families keeping pets, providing them with water daily has become essential, especially for cats, as dehydration can easily lead to urinary tract infections. To address this issue, various pet water fountains are now available on the market, most of which offer automatic water circulation and continuous water supply, thus solving the problem of unattended pet water feeding when no one is home.

[0003] However, current pet water fountains mainly have the following problems: some water fountains do not have a water-electricity separation structure, which may pose a risk of electric shock to pets while drinking water, and the water tank is not easy to clean. The cleaning process may also cause water to enter the circuit and cause a short circuit risk. In addition, some water fountains have unreasonable filter cartridge settings. The filter cartridge is tightly fitted to the cavity in which it is placed, and water will accumulate on the bottom of the filter cartridge. The accumulated water is prone to bacterial growth, which not only shortens the service life of the filter cartridge, but also easily causes secondary pollution to the water. Utility Model Content

Detailed Implementation

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic pet water fountain includes a base 1 with a water tank 2 mounted on it. The water tank 2 stores drinking water for the pet. The base 1 and the water tank 2 are separate units, allowing the water tank 2 to be removed individually for cleaning, making cleaning extremely convenient. Figure 6 As shown, the top edge of the water tank 2 is provided with a wire passage notch 24. When it is necessary to heat the water in the water tank 2, the heating device is placed in the water tank 2, and the power cord can be led out from the wire passage notch 24.

[0029] The water tank 2 has a return water tray 3 on top, a drinking tray 4 on top of the return water tray 3, and a water outlet 5 on the drinking tray 4. Water flowing from the water outlet 5 flows into the drinking tray 4, allowing the pet to drink. The drinking tray 4 has protruding extensions 42 on both sides for easy access. The bottom of the water tank 2 has a suction chamber shell 21, inside which is a water pump impeller 22. Figure 6 As shown, the bottom of the water tank 2 is provided with a support shaft 23, and the pump impeller 22 is rotatably mounted on the support shaft 23. This structure facilitates the free rotation of the pump impeller 22 around the support shaft 23.

[0030] A motor 6 is housed within the base 1. A non-contact magnetic coupling 7 connects the motor 6 to the impeller 22, allowing the motor 6 to drive the impeller 22 to rotate. The motor 6 is fixed to the base 1 by a silicone bracket 61, which provides excellent shock absorption, resulting in quieter operation and pet-friendly operation. The non-contact magnetic coupling 7 includes a driving magnetic block 71 and a driven magnetic block 72, both of which are annular plates with N and S-level spaced magnetization. The driving magnetic block 71 is connected to the motor 6 via the magnetic bracket 62, while the driven magnetic block 72 is sealed and enclosed at the bottom of the impeller 22. When the driving magnetic block 71 rotates, it drives the driven magnetic block 72 to rotate, thus rotating the impeller 22. This achieves non-contact torque transmission, enabling complete separation of water and electricity and improving safety. Furthermore, the driven magnetic block 72 is sealed and enclosed at the bottom of the pump impeller 22, which can effectively prevent water pollution.

[0031] The suction chamber shell 21 is connected to a water guide pipe 8 extending to the water outlet 5. The water guide pipe 8 guides the water inside the suction chamber shell 21 to the water outlet 5. The motor 6 drives the pump impeller 22 to rotate, thereby pumping the water inside the suction chamber shell 21 to the water outlet 5 through the water guide pipe 8. Water from the water tank 1 is continuously replenished into the suction chamber shell 21. Figure 4 As shown, the bottom of the water outlet 5 is provided with an interface 51, and the water guide pipe 8 is inserted into the liquid suction chamber shell 21 and passes through the return water plate 3 to connect with the interface 51. This structure facilitates the formation of a water supply channel from the liquid suction chamber shell 21 to the water outlet 5.

[0032] The drinking water tray 4 is equipped with a return water inlet 41 that connects to the return water tray 3. When the water level in the drinking water tray 4 reaches a certain point, water will flow from the return water inlet 41 into the return water tray 3. Combined with... Figure 5 As shown, the return water tray 3 is equipped with a water receiving trough 31 corresponding to the return water inlet 41. The bottom of the water receiving trough 31 is equipped with a water outlet 311. The water receiving trough 31 is equipped with a filter screen assembly 9. The water flowing out of the return water inlet 41 is filtered by the filter screen assembly 9, mainly to filter hair and other pollutants. The filter screen assembly 9 includes a filter screen bracket 91, on which a stainless steel filter screen 92 is mounted. The filter screen bracket 91 is installed inside the water receiving trough 31. This structure facilitates the installation and fixation of the filter screen assembly 9 and its daily cleaning.

[0033] The return water tray 3 is equipped with a water collection groove 32. A water outlet 321, resting against the outer wall of the water guide pipe 8, is located on one side of the water collection groove 32. Water in the return water tray 3 flows out through the water outlet 321 and is then guided through the outer wall of the water guide pipe 8 into the water tank 2. Due to the guiding effect of the outer wall of the water guide pipe 8, water is prevented from dripping directly into the water tank 2, resulting in quieter operation. The bottom surface of the water collection groove 32 is an inclined surface 322 sloping towards the water outlet 321. Parallel filter elements 10 are arranged within the water collection groove 32. A water flow gap is formed between the filter elements 10 and the inclined surface 322. This structure prevents water accumulation between the filter elements 10 and the inclined surface 322, thus preventing long-term water accumulation at the filter elements 10 and the growth of bacteria, extending the service life of the filter elements 10, and reducing the risk of secondary water pollution. A supporting protrusion 323 is provided on the inclined surface 322 to facilitate support of the bottom surface of the filter elements 10.

[0034] Combination Figure 7 As shown, several water guide plates 81 are provided on the outer wall of the water guide pipe 8. The water guide plates 81 extend to the water outlet 321, and the water guide plates 81 facilitate the flow of water from the water outlet 321 to the outer wall of the water guide pipe 8.

[0035] Combination Figure 8 and Figure 9 As shown, a Hall sensor 11 is installed inside the base 1, and a sensing magnet 12 corresponding to the Hall sensor 11 is installed on the bottom wall of the water tank 2. When the water tank 2 is not placed in the correct position, the Hall sensor 11 can detect this and remind the user to correct it. An infrared water level sensor 13 facing the water tank 2 is installed inside the base 1 to detect whether the water tank 2 is low on water and provide a reminder. A button module 14 and a radar module 15 are installed on one side of the base 1. A control module 16 is installed inside the base 1. The motor 6, Hall sensor 11, infrared water level sensor 13, button module 14, and radar module 15 are all electrically connected to the control module 16. The radar module 15 is used to sense the approach of a pet. A recessed groove 101 is provided on the bottom surface of the base 1. The power interface connected to the control module 16 is located in the recessed groove 101. A cable outlet 102 is also provided on one side of the recessed groove, which facilitates the insertion of the power cord. A rubber pad 103 is also provided on the bottom surface of the base 1.

[0036] The working process of this utility model is as follows: When the pet drinks water, the motor 6 drives the pump impeller 22 to rotate through the non-contact magnetic coupling 7, thereby pumping the water in the suction chamber shell 21 to the water outlet 5 through the water guide pipe 8. The water in the water tank 1 is continuously replenished into the suction chamber shell 21, and the water flowing out of the water outlet 5 flows into the drinking tray 4. The pet drinks water through the drinking tray 4. After the water in the drinking tray 4 reaches a certain water level, the water will flow from the return water port 41 to the filter screen assembly 9 for filtration, mainly to filter hair, etc. The filtered water flows to the water collection groove 32 and is further filtered through the filter element 10. The filtered water is guided by the inclined surface 322 to the water outlet 321 and then guided by the water guide plate 81 to the outer wall of the water guide pipe 8, and then guided by the outer wall of the water guide pipe 8 to the water tank 2, thereby forming a water circulation.

[0037] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
