Problems solved by technology

[0002] At present, the ordinary DC switching power supply used in the market can only input 220V voltage, but those higher or lower than this voltage cannot be used. In addition, the DC switching power supply with backup battery used in the past, the The batteries are all dry batteries. When sofas, hospital beds and other equipment suddenly lose power, the dry batteries provide power for them. More troublesome, but also easy to cause pollution to the environment

Abstract

The invention relates to a switching power supply with a rechargeable standby battery, comprising a shell, wherein the shell is internally provided with a switching power supply module, an output and charge module connected with the switching power supply module through a lead and a rechargeable standby battery connected with the output and charge module through a lead. The switching power supplywith the rechargeable standby battery has wider application range and wider voltage input, confirms to voltage standards of different countries, has advantage in the aspect of energy saving and achieves the efficiency of 83 percent; the power supply is made of an environmentally friendly and flame retardant material, thereby being is a device conforming to the accreditation standard; and moreover, the power supply is provided with the standby battery which is rechargeable, thus the power supply can be used under a power-down condition, and the standby battery can not be dead.

Description

technical field [0001] The invention relates to a switching power supply with a rechargeable backup battery, which is mainly used in medical (auxiliary medical) lifting sofas (lifting sofas with massage and heating functions), lifting sick beds and civilian use (power supply for ordinary electrical equipment), assisting rehabilitation treatment (Special sofa, equipment power supply), medical lifting hospital bed power supply and other related products are used for power supply. Background technique [0002] At present, the ordinary DC switching power supply used in the market can only input 220V voltage, but those higher or lower than this voltage cannot be used. In addition, the DC switching power supply with backup battery used in the past, the The batteries are all dry batteries. When sofas, hospital beds and other equipment suddenly lose power, the dry batteries provide power for them. More troublesome, but also easy to pollute the environment. Contents of the inventi...
