Description

TECHNICAL FIELD

[0002] In order to meet the needs of pet drinking water, provide high-quality drinking water experience for pets, pet drinking water machine is developed, and become an important part of pet health.

[0003] Some pet drinking water machines on the market generally use submersible pump to drive water circulation, and its core structure is that the motor drives the impeller to rotate to drive the water in the water tank to be pumped out to the water tray for pets to drink. Although it can provide drinking water for pets, there are still problems. In the design of traditional submersible pump, the bearing works underwater. If the water in the water tank remains for a long time, bacteria can breed and form a sticky biofilm, which can absorb food residues, dust particles and scale such as calcium and magnesium deposits. These impurities will gradually accumulate between the rotating shaft and the bearing of the submersible pump, causing increased friction or even jamming, which ultimately leads to stall failure. Moreover, the existing submersible pump has a single function and lacks certain filtering function, which can only pump the water in the water tank to the water tray for pets to drink, and cannot pre-filter the water in the water tank, so the safety of pets' drinking water cannot be guaranteed.
