Power adapters and tools powered by AC or DC power

Abstract

A power adapter and a tool driven by an AC and DC power supply. The power adapter includes: a DC power adapter suitable for coupling with a DC power supply; the DC power adapter includes: a battery pack interface unit and an interface connection module group, wherein: the battery pack interface unit includes a plurality of battery pack interfaces , the battery pack interface is suitable for connecting to a battery pack of corresponding voltage; the interface connection module set includes an input terminal, an output terminal, and more than two interface connection modules coupled between the input terminal and the output terminal, The interface connection modules correspond to and are coupled to the battery pack interfaces one by one, and the interface connection modules are coupled in a preset connection manner. Applying the above solution can reduce the use cost and subsequent maintenance cost of the tools driven by the AC and DC power sources.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power adapter and a tool driven by an AC or DC power supply. Background technique [0002] Tools driven by alternating current and direct current power, that is, electric tools that can use alternating current (AC) power or direct current (DC) power as the working power supply, including but not limited to air compressors, pressure washers, lawn mowers, chain saws, Cleaning tools, pruning tools, handheld power tools, snow blowers, backpack power tools and more. [0003] Typically, dual purpose power tools operate on AC power when AC power is available. Combination power tools operate on DC power when AC power is not available. By inserting a battery pack into the tool driven by AC and DC power, the tool driven by AC and DC power can obtain DC power for working. [0004] At present, under different working conditions, tools driven by the same AC and DC power supply nee...

AI Technical Summary

Problems solved by technology

[0004] At present, under different working conditions, tools driven by the same AC and DC power supply need to be matched with battery packs of different voltages, and battery packs of each voltage need to be powered by corresponding power adapters for tools driven by AC and DC power sources. Therefore, consumers are using For tools driven by AC and DC power sources, it is necessary to purchase a variety of battery packs with different voltages and corresponding power adapters, which leads to high follow-up maintenance costs and use costs for tools driven by AC and DC power sources.
