[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 and Figure 4In this embodiment of the invention, a pet water fountain based on magnetic drive includes a drinking tray 1, a water storage tank 2, an impeller pump 3, a water supply pipe 4, a filter module 5, a drive motor 6, and a base 7. The base 7 is made of high-strength plastic, forming a sealed cavity. The water storage tank 2 is installed on the base 7 and is located in the middle of the water fountain for storing drinking water. A water level detection sensor is installed at the bottom of the water storage tank 2. When the liquid level reaches the low level, the drive motor 6 is stopped to prevent the drive motor 6 from running dry and being damaged. The drinking tray 1 is installed on the water storage tank 2 for providing water to the pet. The drinking tray 1 is made of stainless steel or ceramic material to ensure safety. For safety and durability, one end of the drinking tray 1 is equipped with a water outlet 9 to guide water lifted from the water storage tank 2 into the drinking tray 1, and the other end of the drinking tray 1 is equipped with a water return outlet 8 to guide the water in the drinking tray 1 back into the water storage tank 2, realizing water circulation. An impeller water pump 3 is installed at the bottom of the water storage tank 2, located at the bottom opening of the water storage tank 2. The impeller water pump 3 includes an impeller housing 301, an impeller 302, a silicone sealing ring 303, an impeller support shaft 304, an impeller permanent magnet 305, and an impeller bottom shell 306. The impeller support shaft 304 is fixed to the inner wall of the water storage tank 2 and is made of self-lubricating plastic to ensure the impeller 302's stability. 2. Regarding quiet operation during rotation, an impeller base shell 306 is fitted onto the impeller support shaft 304. Several impeller permanent magnets 305 are embedded within the impeller base shell 306 for meshing with the drive motor 6, thus causing the impeller to rotate under the drive of the drive motor 6. An impeller 302, fixedly connected to the impeller support shaft 304, is mounted on the impeller base shell 306. The water flow guide vanes of the impeller 302 are arranged in a spiral pattern to optimize the water flow path and improve pumping efficiency. An impeller housing 301 is mounted on the upper part of the impeller 302. The drive motor 6 is installed inside the base 7. The power supply for the drive motor 6 is a low-voltage DC power supply with an operating voltage of 1V to 6V, ensuring operational safety. Suitable for home and pet use, the variable water flow rate is achieved by adjusting the control circuit of the drive motor 6. The drive motor 6 includes a motor body 601, a motor bracket 602, a motor permanent magnet 603, and a permanent magnet bracket 604. The motor bracket 602 is fixedly connected to the base 7. The motor body 601 is installed at the bottom of the motor bracket 602. The permanent magnet bracket 604 is fixedly installed on the output shaft of the motor body 601. The motor permanent magnet 603 is installed on the permanent magnet bracket 604. A water supply pipe 4 is installed on the impeller housing 301 of the impeller water pump 3. The water supply pipe 4 is made of food-grade plastic and the top of the water supply pipe 4 is connected to the outlet 9.

[0026] A silicone sealing ring 303 is installed on the outer wall of the impeller housing 301. The silicone sealing ring 303 is located between the impeller housing 301 and the bottom opening of the water storage tank 2. The impeller housing 301 is tightly connected to the bottom of the water storage tank 2 through the silicone sealing ring 303. The joint between the water storage tank 2 and the impeller water pump 3 adopts an embedded sealing design, and the leakage prevention performance is further enhanced by the silicone sealing ring 303. The impeller housing 301 is made of high-strength non-magnetic material and has a detachable design, which is convenient for users to clean and maintain.

[0027] The motor permanent magnet 603 and the impeller permanent magnet 305 are magnetically coupled through the impeller housing 301 at the bottom of the water storage tank 2. The coupling between the motor permanent magnet 603 and the impeller permanent magnet 305 has a slippage protection function. When the impeller 302 is overloaded, the motor 6 is protected from overload damage by magnetic slippage protection.

[0028] Impeller 302 is disc-shaped with a central recess. The difference between the outer diameter of the impeller shaft and the inner diameter of the central recess is less than 0.5 mm to ensure the stability of impeller 302 when rotating at high speed.

[0029] Both the motor permanent magnet 603 and the impeller permanent magnet 305 adopt a multi-pole annular design with at least three magnets. Each magnet has multiple pairs of magnetic poles to improve magnetic force transmission efficiency and reduce sliding losses during operation. The permanent magnets are installed inside the impeller 302 with a waterproof seal to ensure that no rust occurs during use.

[0030] The bottom of the drive motor 6 is equipped with an elastic anti-vibration pad layer. The drive motor 6 and the base 7 are connected by the elastic anti-vibration pad to absorb the vibration generated during operation and reduce noise.

[0031] The base 7 is equipped with non-slip feet made of silicone material to prevent the device from sliding or tipping over during pet use.

[0032] A filter module 5 is installed in the water storage tank 2 directly below the return water inlet 8. The filter module 5 adopts a pluggable design and includes three layers: activated carbon filter, fine mesh filter layer, and ion exchange resin. It is used to remove impurities and odors from the water and ensure water quality. Users can replace the activated carbon filter and fine mesh filter layer regularly to ensure long-term water quality.

[0033] Water tank 2 is made of transparent material and is equipped with scale markings to show the water level and drinking volume, preventing pets from not drinking enough water. Water tank 2 features a fully detachable design, and the inner surface of water tank 2 is polished and designed without dead corners to reduce the growth of scale and bacteria, making it easy for users to clean daily.

[0034] This utility model can be equipped with an intelligent control module, including a water sensor and a timer switch, which can issue a reminder when the water is insufficient or shut down the impeller pump 3 at a set time to save energy, realize timed operation or low water alarm function, and further improve the user experience.

[0035] Please see Figure 3 The working principle of this utility model is as follows: When in use, the drive motor 6 is turned on. When the drive motor 6 is running, the magnetic force drives the impeller 302 to rotate without contact through the impeller housing 301. The water in the water storage tank 2 is lifted to the drinking tray 1 by the impeller water pump 3 for the pet to drink. There is a return water port 8 at the other end of the drinking tray 1. After the water flows through the return water port 8 of the drinking tray 1, it enters the filter module 5. The filter module 5 filters the water and then returns it to the water storage tank 2 to achieve circulation.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
