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

It is well known that the exterior walls of buildings such as houses or buildings are mostly constructed of cement, brick, metal, non-metal, glass, etc. Because of the long-term impact of ambient air, dust and sunlight and rain, they are all Regular cleaning is required to maintain the clean appearance.

At present, the cleaning of external walls of buildings has gradually evolved from manual to automatic or semi-automatic directions, in order to reduce many dangers caused by artificial construction. For example, the wall washer disclosed in Taiwan Patent Announcements M327752, M407717, M442887, M509691, etc., is equipped with two cylindrical brush wheels on a machine body at the same time, and the two cylindrical brush wheels are used to roll and contact the wall surface for brushing. The wall washer uses the way of hanging from the top floor of the building by rope to vertically lift along the outer wall of the building to wash the wall; wherein, the wall washer will form a cleaning track on the wall when moving and brushing the wall. The cleaning width of the cleaning trajectory 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 pivotally mounted on the machine body with its two ends, and is rotated by the drive of the motor. When the length of the cylindrical brush wheel is longer, only the two ends of the cylindrical brush wheel are supported, resulting in The middle part of the cylindrical brush wheel is prone to sway during the rotation process, resulting in an uneven size of the rotary cutting force applied to the two ends of the brush wheel and the middle part relative to the wall surface, and even different in the cleaning trajectory The force of the rotating brush causes inconsistent cleanliness of the wall washing.

In order to improve the above phenomenon, if the middle section between the two ends of the cylindrical brush wheel Adding multiple support points on the part can improve the problem of sloshing in the middle of the cylindrical brush wheel, but the cylindrical brush wheel will form a gap that is not brushed in the cleaning trajectory due to the spacing of the above support points when washing the wall surface As a result, the cleanliness of the wall washing will also be inconsistent.

In addition, the power transmitted by the motor to the cylindrical brush wheel will gradually decrease as the length of the cylindrical brush wheel becomes longer, so the longer the length of the cylindrical brush wheel, the more the width of the cleaning wheel on the wall When it is wide, the power transmitted from the motor to the end of the shaft of the brush wheel will be weakened by the resistance, which will affect the inconsistent cleaning effect of the double-end wheel surface of the longer cylindrical brush wheel when washing the wall, so it needs to be improved. .
