Patent attributes
A handheld pressure washer device is provided that is electrically driven and does not require an external pump. The device comprises a handle section, a barrel section, and a water intake that is configured to secure to a standard water hose. The device includes a battery pack or connection to an external electrical power source, which delivers electrical power to an electric motor within the barrel section. The electric motor drives a driveshaft, which imparts rotary motion on an impeller within the barrel section. The impeller pressurizes and accelerates water within a conduit, causing the water to rapidly pass through a stator and through the outlet of the device. The speed of the electric motor is controlled by a user trigger, while the intake and outlet include coupling to affix attachments and water hoses thereto, respectively. The device provides a compact, handheld unit for pressurizing water from a hose.
