High pressure washer

Abstract

The present invention relates to the field of the washer technology, especially to a high pressure washer. The high pressure washer comprises a power device. The power device includes: a motor; a first power device configured to connect the motor and supply electric power to the motor under control, wherein the first power device is internally provided with an energy storage module configured to store electric power; a second power device configured to connect the energy storage module of the first power device and the motor and selectively supply electric power to the energy storage module of the first power module and / or the motor; a detection circuit configured to connect the second power device and detect the output voltage of the second power device; a controller configured to connect the detection circuit and control the switching of the power device between the preset power modes according to the detection result of the detection circuit. Compared with the prior art, the high pressure washer employs the interworking power supply mode of a first power device and a second power device, so that when any one of the two power devices cannot supply power, the other power device is able to replenish electric power, therefore the high pressure washer is capable of sustainable usage.

Description

technical field [0001] The invention relates to the technical field of cleaning machines, in particular to a high-pressure cleaning machine. Background technique [0002] A high-pressure cleaner is a machine that uses a power device to make a high-pressure plunger pump generate high-pressure water to wash the surface of an object. It can peel off and wash away the dirt to achieve the purpose of cleaning the surface of the object. High pressure cleaning is one of the most scientific, economical and environmentally friendly cleaning methods in the world. Most of the existing high-pressure cleaners are powered by AC power supply devices, which are generally connected to 220V AC through a plug or a power strip. However, the working environment of high-pressure cleaners is relatively humid, which brings potential danger to operation and installation. Not available. In addition, the high-pressure washer needs to be connected to 220V AC before it can work normally. The high-pres...

Problems solved by technology

Most of the existing high-pressure cleaners use AC power supply devices for power supply. Generally, they are connected to 220V AC power through plugs or extension strips. However, the working environment of high-pressure cleaners is relatively humid, which brings potential dangers to operation and installation. In some special cases, Not available

In addition, the high-pressure cleaner needs to be connected to 220V AC before it can work normally. If it is outdoors or where there is no 220V AC, the high-pressure cleaner cannot be used.
