The present invention relates to the field of clean technology, particular to a high-pressure cleaning machine using both alternating current and direct current.
At present, the power supply mode of the cleaning machine usually includes three categories, the first one uses alternating-current power supply, the second one uses direct-current power supply, and the third one uses AC/DC general power supply. For the cleaning machine powered by alternating-current power supply, its range of motion is limited by the position of the power socket and the length of the wire, and it is inconvenient to use; for the cleaning machine powered by direct-current power supply, in order to ensure the lightness of moving, the battery pack that it carries is often reduced in the design process, so the capacity of the battery pack is also reduced accordingly, which will lead to the shortening of the working time of the cleaning machine, and even the situation that the rated voltage of the starting cleaning machine cannot be reached. There are many kinds of battery packs on the market, and there are many types of corresponding chargers, the versatility of the two is low and these two is prone to be confused when used together. Therefore, a cleaning machine with AC/DC power supply together is the best solution.
However, the design of the cleaning machine of AC/DC power supply in the prior art is not humane enough, the charging of its battery pack needs to manually plug the patch cord into the external power supply, and the plug part is easy to loosen after multiple plugging, and can only be used in one of the direct-current power supply and the alternating-current power supply, and these two cannot cooperate to supply power to the cleaning machine simultaneously, and the operation convenience and safety of the cleaning machine are greatly reduced.
According to the existing problems in the prior art, a high-pressure cleaning machine using both alternating current and direct current is provided, which aims to solve the issue that the cleaning machine in the prior art cannot be shared by alternating-current power and direct-current power.
