Description

Brush-type wall washer for large cleaning width

Technical field

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.

Background technique

As we all know, 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., all have two cylindrical brush wheels disposed on one body, and are brushed by two tubular brush wheels to contact the wall surface for cleaning. 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, which causes 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. The brushing force, which in turn causes the cleanliness of the wall to be inconsistent.

In order to improve the above phenomenon, if a plurality of support points are added in the middle portion between the double ends of the cylindrical brush wheel, the problem of sloshing in the middle portion of the cylindrical brush wheel can be improved, but the cylindrical brush wheel is caused by brushing the wall surface. The gap between the above-mentioned support points forms a gap in the cleaning track that is not brushed, and thus the cleanliness of the wall washing is inconsistent.

In addition, since the power transmitted by the motor to the cylindrical brush wheel is gradually reduced as the length of the cylindrical brush wheel is longer, the longer the length of the cylindrical brush wheel, that is, the cleaning width of the brush wheel against the wall surface When it is wide, the power transmitted from the motor to the end of the brush wheel shaft is weakened by the resistance, which in turn affects the inconsistent cleaning effect of the double-ended wheel surface of the long tubular brush wheel when scrubbing the wall surface, so it needs to be improved. .
