The invention relates to an electrical device for an aquarium, and more particularly to an aquarium power adapter and an aquarium power supply system.
Aquariums often use some electrical equipment, such as pumps, heaters, lighting fixtures, etc. These electrical equipment often have their own AC-to-DC adapters. As shown in
The present invention provides an aquarium power adapter and an aquarium power supply system. The aquarium power adapter of the present invention includes a boost/buck circuit which has an input port and a plurality of output ports. The input port is connected to a direct current output port of the power supply system. A first direct current is input to the input port and boosted or bucked through the boost/buck circuit, and a second direct current having a higher or lower voltage is output through the output port. Therefore, only one power adapter is needed for the plurality of electrical devices, and correspondingly, only one power supply system is needed.
The aquarium power adapter in accordance with an exemplary embodiment of the invention includes a housing disposed on an outer wall of an aquarium, a circuit board disposed in the housing, a boost/buck circuit disposed on the circuit board and comprising an input port and a plurality of output ports, wherein a first direct current is input to the input port and a second direct current is output from at least one of the output ports, an input connector electrically connected to the input port; and a plurality of output connectors electrically connected to the output ports respectively.
The aquarium power supply system in accordance with an exemplary embodiment of the invention includes a power supply comprising an alternating current input port and a direct current output port, wherein an alternating current is input into an AC-DC converting circuit through the alternating current input port, and a first direct current is output from the direct current output port; and a power adapter comprising a boost/buck circuit, wherein the boost/buck circuit comprises an input port and a plurality of output ports, wherein the first direct current is input to the input port and a second direct current is output from at least one of the output ports.
A detailed description is given in the following embodiments with reference to the accompanying drawings.
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

The housing 10 is a flat rectangular body and can be disposed on an outer wall of an aquarium. The housing 10 includes a first half housing 11 and a second half housing 12, and the first half housing 11 and a second half housing 12 are combined to form an accommodating space S. The circuit board 20 is disposed in the accommodating space S. The boost/buck circuit 30 is formed on the circuit board 20. The boost/buck circuit 30 has an input port 31 and a plurality of output ports 32. A first direct current is input to the input port 31, and a second direct current is output from at least one of the output ports 32. The boost/buck circuit 30 can be a combination of a boost circuit and a buck circuit, such as a circuit including an inductor, a capacitor, and a diode, so that the voltage of the second direct current can be higher or lower than the voltage of the first direct current. For example, the first direct current may be an output direct current through an AC/DC transformer. For example, the AC/DC transformer converts an alternating current of 220V to a first direct current of 24V. The first direct current having a voltage of 24V may be converted into a second direct current having a voltage of 12V via the boost/buck circuit 30.
The input connector 40 is electrically connected to the input port 31 of the boost/buck circuit 30. The plurality of output connectors 50 are electrically connected to the output ports 32 of the boost/buck circuit 30, respectively. The various electrical equipment used in the aquarium, such as water pumps, heaters or lamps, have different operating voltages. Therefore the voltage of the second direct current through each of the output connectors 50 can also be adjusted for the electrical equipment. In addition, the input connector 40 and the output connectors 50 are electrically connected to the circuit board 20 via opposite sides of the housing 10.

The aquarium power adapter 100 of the present invention has a boost/buck circuit 30. The boost/buck circuit 30 has an input port 31 and a plurality of output ports 32. A first direct current is input to the input port 31, and a second direct current is output from at least one of the plurality of output ports 32, which can be provided to a plurality of electrical devices for the aquarium. Therefore, only one power supply devices is needed for the plurality of electrical devices, thereby not only reducing the complexity of the device, but also avoiding the safety problem brought by the high voltage.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
