The invention relates to the structure technology of a wall washer, in particular to a brush-type wall washer suitable for a large cleaning width.

It is known that the external walls of buildings such as general houses or buildings are mostly made of cement, brick, metal, non-metal, glass, etc. Due to the long-term exposure to ambient air, dust and sun and rain, Regular cleaning is required to maintain a clean appearance.

At present, the cleaning work of the external walls of buildings has been gradually developed by manpower towards automatic or semi-automatic direction to reduce the many dangers caused by artificial construction. For example, the wall washers disclosed in Taiwan Patent Publications M327752, M407717, M442887, M509691, etc. are all configured with two tubular brush wheels on one body, and the two cylindrical brush wheels are used to roll the wall surface for brushing. The wall washer uses a rope to hang from the top floor of the building and vertically lifts the wall along the outer wall of the building; wherein the wall washer forms a cleaning track on the wall when moving and scrubbing the wall surface. The cleaning width of the cleaning track is determined by the length of the cylindrical brush wheel, that is, the longer the length of the cylindrical brush wheel, the larger the cleaning width.

However, the cylindrical brush wheel is pivoted on the body by the double ends thereof, and is driven to rotate by the driving of the motor. When the length of the cylindrical brush wheel is longer, the cylindrical brush wheel is only supported at both ends, resulting in The middle part of the cylindrical brush wheel is easy to sway during the rotation process, causing the double-end and middle-end parts of the brush wheel to be unevenly distributed in the magnitude of the rotary cutting force applied to the wall surface, and even different in the cleaning track.
