Disclosed are a water pump and an aquarium equipment that includes the water pump. The water pump includes a stator, a rotor assembly, an impeller, and a power generation induction module. The stator includes a U-shaped iron core and a coil winding wound around the U-shaped iron core. The coil winding is connected to an external power source. The rotor assembly includes a rotating shaft and a permanent magnet rotor. The impeller is connected to the rotating shaft or to the permanent magnet rotor. The power generation induction module is spaced apart from the rotor assembly. The rotor assembly and the power generation induction module are both disposed within a range of a magnetic field at an opening of the U-shaped iron core. The power generation induction module is electrically connected to an electric equipment.

A vortex fountain or waterer that incorporates measures to induce swirl in liquid moving toward a drain opening of the fountain to inhibit the accumulation of debris is provided. The fountain may have a bowl including a base surface having a slope that is configured to create a vortex in the liquid flowing toward the drain opening to induce movement of a quantity of water, where the bowl is located above a basin configured to hold the liquid. The fountain may also include a pump outlet jet that can be positioned about the bowl to induce swirl about the bowl. The fountain may also include a drain tube located beneath the drain opening, and an extended guide tube extending downwardly towards the bottom of the basin. When the liquid passes through the drain, drain tube, and guide tube, oxygen is incorporated into the liquid as the liquid reaches the basin.
