Battery box UPS (uninterruptible power supply)

Abstract

The invention relates to a battery box UPS (uninterruptible power supply). According to the invention, a direct current main power supply outputted through a USB interface line after carrying out voltage reduction, rectification and filtering on the mains supply and an alkaline battery or a battery standby power supply in an electric equipment battery box form a set of battery box UPS system through a power supply management / switching circuit and a battery box contact piece sleeve device. When the power is interrupted, the battery standby power supply is connected automatically by the power supply management / switching circuit so as to supply power; and when the power is recovered, the battery power supply is disconnected automatically by the power supply management / switching circuit, and the USB interface line main power supply is connected. The advantages are that the battery box UPS is convenient and simple to use, and everybody can realize quick assembly and disassembly; the battery box UPS is particularly suitable for electric appliances such as a household gas cooker and a water heater which are not provided with a dedicated external power supply interface so as to realize uninterruptible power supply; sufficient powerful current of the external power supply can also repair a fault of insensitive startup of many electromagnetic valves, the reliability of the electric equipment in a severe environment is improved, and a lot of undeserved maintenance cost can be saved for electric appliance users; and the battery box UPS is suitable for both urban and rural areas.

Description

technical field [0001] The invention relates to the technical field of uninterruptible power supply (UPS), in particular to a battery box UPS power supply. Background technique [0002] At present, the gas stoves and flue-type water heaters we use in our daily life can only be powered by 3v / 1.5v batteries, and there are very few interface devices for external power adapters. Even if rechargeable batteries are used instead of alkaline batteries, it is also necessary Facing the trouble of replacing the battery, and for electrical appliances with increasingly perfect additional circuits, it means that the power consumption is also greater, and the battery seems to be unable to do what it wants. From the perspective of recycling energy, battery power supply is only suitable for mobile electrical appliances. This power supply method is easy to cause many false faults due to insufficient power supply. Happened, even if it can be ignited, it will be extinguished soon. This kind o...

Problems solved by technology

From the perspective of recycling energy, battery power supply is only suitable for mobile electrical appliances. This power supply method is easy to cause many false faults due to insufficient power supply. Happened, even if it can be ignited, it will go out soon

This kind of problem will quickly drain the battery. The chargers on the market are mainly 5v / USB interface, so it is very easy to obtain. It is urgent to design and use the power supply of 5v / USB interface to solve the above common circuit problems.
