Background

Currently, power tools generally include three types, one type powered by an ac power source, another type powered by a dc power source, and another type powered by an ac/dc power source. For power tools powered by ac power, the power tool is typically used only in locations closer to the power outlet; the working range of the dust collector is wider, if the electric wire is connected to an alternating current power supply, the dust collector needs to be dragged to move around to work, and the moving convenience of the dust collector is seriously affected. For the dust collector powered by the direct current power supply, the capacity of the battery pack is limited, the electric energy storage of the direct current power supply is limited, the working time of the dust collector is shorter, and the power and the performance of the dust collector are reduced. The battery packs in the market are various in variety, corresponding chargers are also various in variety, and the universality of the combination of the battery packs and the chargers is low and the battery packs are easy to confuse. When the dust collector works at a place close to the AC power socket and an AC power supply is required to be used, a rectifier and other conversion structures for converting the AC power into the DC power are needed to be arranged in the dust collector, so that the production cost and the volume of the product are increased. For ac/dc general-purpose cleaners, there are generally the following problems: the output voltage and the electric energy reserve of the existing direct current power supply are limited, the input voltage requirement of the dust collector is often not met, the power supply time is short, and the working efficiency of the dust collector is greatly reduced. Therefore, at present, for the dust collector with high voltage and high power requirements, an alternating current power supply mode is generally selected, and the use is extremely inconvenient.

In view of the foregoing, there is a need for an improved ac/dc cleaner to solve the above problems.
