Automatic Backup Power Controller for Aquarium Use

Abstract

An automatic backup power controller for aquarium use. When the Backup Box taught by the present invention has normal power applied to it, it energizes the 12-24 volt DC coil and closes the Normally Open side of the relay which sends 12-24 volts through the relay and to the connected pump or power head that is connected to the output port on the Backup Box. When normal power is lost the coil will DE-energize thus opening the Normally Open side of the relay in turn causing the Normally Closed side of the relay to close and send 12-24 volts DC battery power through the Normally Closed side of the relay through the fuse and to the Output connection on the Backup Box. The Output connection on the Backup Box is common to both the Normally Open and Normally Closed terminals on the Relay depending on the state it is in.

In the following detailed description of the invention of exemplary embodiments of the invention, reference is made to the accompanying drawings (where like numbers represent like elements), which form a part hereof, and in which is shown by way of illustration specific exemplary embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, but other embodiments may be utilized, and logical, mechanical, electrical, and other changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.

In the following description, numerous specific details are set forth to provide a thorough understanding of the invention. However, it is understood that the invention may be practiced without these specific details. In other instances, well-known structures and techniques known to one of ordinary skill in the art have not been shown in detail in order not to obscure the invention. Referring to the figures, it is possible to see the various major elements constituting the apparatus of the present invention.

The device of the present invention is an automatic backup power controller for aquarium use. The present invention is distinguishable over prior art system, which incorporated uninterrupted power supplies (UPS), invertors, batteries, and related combinations unsuccessfully. The present invention is a 24 volt system, unlike the various attempted prior art solutions which are all 12 volt based systems. Because of the present invention’s design as a 24 volt system, it is designed specifically for DC powered aquarium pumps and does not require an inverter, or transformer like other prior art solutions.

One advantage of the design of the present invention over the prior art is that it uses the same pump that is connected to normal power as well as battery power by incorporating a 24 volt DC powered relay. The present invention does not use multiple pumps and no air pumps like other prior art system and results in a much simpler and direct component and installation compared to those currently offered and known in the prior art.

The present invention also uses an automatic power switch and an 8 point DPDT relay on a 10 amp circuit in comparison to the 6 point relays on 30 amp circuits known in the prior art.

Now referring to FIGS. 8-11, the Backup Box as taught by the present invention is a box that contains 3 5.5x2.1 mm female DC power connectors. One for normal power one for battery power and one is output power. The normal power is powered by the pumps normal (power brick). The battery power is wired to the customer’s choice of an AH battery setup and then connected to the battery connector on the Backup Box. And the 3rd and final connector connects a cable from the Backup Box to the pump or power head.

Now referring to FIGS. 2, 3, 5, 6, and 7, inside the Backup Box there is a 12-24 volt DC DPDT relay The normal power connects from the 5.5x2.1 mm connection to the Normally Open contacts on the relay. It also connects to the 12-24 volt coil that pulls the relay in when 12-24 volt DC power is applied. The Battery power from the customers AH battery setup connects on battery connection on the Backup Box which connects to the Normally Closed side of the relay. The output side of the DPDT relay connects to the output port on the Backup Box which connects to the pump or power head.

As shown in FIGS. 2 and 6, the relay is comprised of one or more output connections, one or more DPDT contacts, and a coil. The relay is located inside an enclosed box housing which retains all the components of the present invention. The relay has both normally open contacts and normally closed contacts.

The normal power connects from the 5.5x2.1 mm jack/connection to the Normally Open contacts on the relay. It also connects to the 12-24 volt coil that pulls the relay in when 12-24 volt DC power is applied. The Battery power from the customers AH battery setup connects on battery connection on the Backup Box which connects to the Normally Closed side of the relay. The output side of the DPDT relay connects to the output port on the Backup Box which connects to the pump or power head.

Now referring to FIGS. 3 and 5, additional wiring of the present invention is illustrated. Here it is shown that the relay out is connected to the meter output and output power. The Battery power from the customers AH battery setup connects on battery connection on the Backup Box which connects to the Normally Closed side of the relay. The output side of the DPDT relay connects to the output port on the Backup Box which connects to the pump or power head. Additionally, the feed mode button, typically set for 10 minutes, is connected to a time delay board for providing the feed mode functionality.

In use, when the Backup Box taught by the present invention has normal power applied to it, it energizes the 12-24 volt DC coil and closes the Normally Open side of the relay which sends 12-24 volts through the relay and to the connected pump or power head that is connected to the output port on the Backup Box. When normal power is lost the coil will DE-energize thus opening the Normally Open side of the relay in turn causing the Normally Closed side of the relay to close and send 12-24 volts DC battery power through the Normally Closed side of the relay through the fuse and to the Output connection on the Backup Box.

The Output connection on the Backup Box is common to both the Normally Open and Normally Closed terminals on the Relay depending on the state it is in. So, with a loss of power to the 12-24 volt coil the Backup Box will automatically change from normal “plugged in” power to the battery power with no effort from the user. So, no matter where they may be if the power goes out the aquarium will continue to run for however long the user has set up their AH battery setup. When normal power is restored, it will energize the coil and automatically switch back to normal “plugged in” power again with no effort from the customer. Then if the customers AH battery setup is equipped with a trickle charger and the power is restored it will automatically recharge the batteries again with no effort from the user.

As shown in FIGS. 1, 4, and 8, the Backup Box as taught by the present invention contains a 12-24 volt battery meter display as well to let the user know how much the battery is charged. It also has an indicator light for both normal and battery power letting the user know that power is available for one or both power supplies. As shown in FIG. 10, on a left side when facing the front face with the display, a feed mode button is located for manually placing the box into a feed mode state. On a right side when facing the front face with the display, two fuses are located providing a fused connection to output connections. As shown in FIGS. 8-11, on a bottom side when facing the front face with the display, a 24 volt output, a battery power input, and a normal power input are provided, which are standard 5.5 x 2.1 mm DC power jacks/connectors.

The Battery setup is totally up to the user. A user can use a simple inexpensive 12-24 volt DC 7AH setup or they can make their setup more expensive and last 100’s of hours. The choice is theirs. This invention will make having backup power available in the event of a power outage affordable as well as easy.

With respect to the construction and physical components, all wiring is 14 gage THHN. All parts are rated for 10 Amps. There is a feed mode button on the side of the unit as shown in FIG. 10 to shut down output power for 10 Mins.

Now referring to FIG. 7, in an alternative embodiment, the present invention can also incorporate a WIFI module/power relay in the box which controls the feed mode and off modes. In this embodiment, the relay output is connected to the batter meter/display as well as the output power jack/connector of the battery backup box, and a WiFi module/power relay and timer are connected between the output power jack/connecter and the relay. In this embodiment, the normal power connects from the 5.5x2.1 mm jack/connection to the Normally Open contacts on the relay. A green LED light is used to provide a visual monitor of the normal power input status. It also connects to the 12-24 volt coil that pulls the relay in when 12-24 volt DC power is applied. The Battery power from the customers AH battery setup connects on battery connection on the Backup Box which connects to the Normally Closed side of the relay. A red LED light is used to provide a visual monitor of the batter power input status. The output side of the DPDT relay connects to the output port on the Backup Box which connects to the pump or power head. Finally, fuses a can be added to the normal power input and battery power input lines in combination or individually to provide additional protection to the relay and components as shown in FIGS. 3,5, and 7.

Thus, it is appreciated that the optimum dimensional relationships for the parts of the invention, to include variation in size, materials, shape, form, function, and manner of operation, assembly, and use, are deemed readily apparent and obvious to one of ordinary skill in the art, and all equivalent relationships to those illustrated in the drawings and described in the above description are intended to be encompassed by the present invention.

Furthermore, other areas of art may benefit from this method and adjustments to the design are anticipated. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
