Disclosed is an aquarium that includes a tank, a magnetic induction transmission apparatus, and a first electric equipment disposed in the tank. The magnetic induction transmission apparatus includes a driving module and a receiving module. The driving module is disposed outside the tank and adjacent to a tank wall of the tank and is configured to be separable from the tank, and the receiving module is disposed on the tank wall of the tank and disposed corresponding to a position of the driving module. The driving module is connected to an external power source. The receiving module is connected to the first electric equipment and is operative to generate an induced current when the driving module is powered on.

Provided are a power generation apparatus and an aquarium equipment. The power generation apparatus includes a water pump and a magnetic induction generator. The water pump includes a housing, a stator mounted in the housing, a first rotor assembly, and an impeller connected to the first rotor assembly. The first rotor assembly includes a first permanent magnet rotor and a first rotating shaft disposed at an axis of the first permanent magnet rotor. The first permanent magnet rotor is disposed adjacent to the stator. The magnetic induction generator is disposed adjacent to the stator or to the first permanent magnet rotor and is operative to be coupled to an electric device. The stator includes a coil winding operative to be coupled to an external power source, so that when the coil winding is coupled to an input alternating current, the first permanent magnet rotor rotates enabling the magnetic induction generator to generate an induced current to power up the electric device. The aquarium equipment includes the power generation apparatus described above.

Provided are a power generation apparatus and an aquarium equipment including the power generation apparatus. The power generation apparatus includes a water pump and a power generation induction coil. The water pump includes a stator, a rotor assembly, and an impeller. The rotor assembly is coupled to the impeller, the stator includes a U-shaped iron core and a coil winding wound around the U-shaped iron core. The coil winding is operative to be coupled to an external power source. The rotor assembly includes a rotating shaft and a permanent magnet rotor coupled to the rotating shaft. The power generation induction coil is wound around an exterior of the permanent magnet rotor and coupled to an electric device. The permanent magnet rotor is disposed at an open end of the U-shaped iron core. When the coil winding is energized, the permanent magnet rotor rotates relative to the power generation induction coil enabling the power generation induction coil to generate an induced current to power up the electric device.

The present disclosure relates to the technical field of aquarium equipment. Disclosed is an aquarium that includes a tank, an electric device disposed in the tank, a first conductive contact configured to be coupled to an external power source, and a second conductive contact coupled to the electric device. The first conductive contact is configured to come into contact with the second conductive contact to power up the electric device.

An aquarium has wireless lighting which is configured to turn on a lighting device provided inside the aquarium and vertically move the lighting device in water by a wireless magnetic resonance method. Therefore, a light that can be maintained in a submerged state may be provided, thereby providing better aesthetic effects than existing lights of aquariums. In addition, additional devices such as a filter can be moved in water by using a magnetic field, thereby improving functional effects.

A combination night light and aquarium is disclosed having a bowl including a body portion, a bottom portion connected to the body portion, and a neck portion at a top of the bowl defining an opening at the top of the bowl, wherein the bottom portion is dimensioned to fit on the central portion when the bowl is placed on top of the base; a lid dimensioned to fit over the first opening at the top of the bowl, wherein the lid includes an inner edge portion defining an opening through the lid; and a hollow member removably or fixedly attached to the lid, the member extending into the bowl and dimensioned to receive light emitted by the one or more lighting elements when the lid is placed on top of the bowl.

A lamp and fish tank combination assembly for emitting light downwardly towards the aquarium and outwardly from a light source includes a tank that is filled with water and houses fish. A lighting unit is positioned on top of the tank. The lighting unit emits light downwardly into the tank and laterally from the lighting unit when the lighting unit is turned on.

Modular habitat structure (MHS) which can accommodate one or more live inhabitants is comprised of a rigid pillar which extends linearly away from a base end toward an upper end. A plurality of major system components are disposed at different locations along a length of the rigid pillar. Each of the major system components is comprised of modular segments which individually extend circumferentially around at least a portion of the rigid pillar. The modular configuration of the segments allows user configuration of the MHS by selectively adding or removing one or more segments of each of the major system components.

Embodiments are described of a beverage dispensing system configured to give the illusion it dispenses aquarium water.

A fluid-dynamic pump which is suitable for circulating water in an aquarium includes a rotary device, an electric motor configured to move the rotary device, a pump body which houses a printed circuit board which that controls the electric motor and a temperature sensor that detects the temperature of the water of the aquarium. The temperature sensor is positioned on the pump body.
