Description

Brush dish type wall washer suitable for large cleaning width

Technical Field

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

Background

As is well known, the outer walls of buildings such as houses and buildings are mostly constructed of cement, tiles, metal, nonmetal, glass, etc., and are regularly cleaned to maintain the cleanness of the appearance due to the influence of ambient air, dust, and sun and rain.

At present, the cleaning work of the outer wall of the building is gradually developed towards the automatic or semi-automatic direction by manpower so as to reduce a plurality of dangers easily caused by manual construction. For example, in the wall washers disclosed in taiwan patent publications M327752, M407717, M442887, M509691, etc., two cylindrical brush wheels are simultaneously disposed on a machine body, and the wall is washed by rolling and contacting the two cylindrical brush wheels with the wall, and the wall is washed by vertically lifting and lowering the wall along the outer wall of the building by means of a rope suspended from the top floor of the building; the wall washer can form a cleaning track on the wall surface when moving and brushing the wall surface, and the cleaning width of the cleaning track is determined by the length of the cylindrical brush wheel, namely the longer the length of the cylindrical brush wheel is, the larger the cleaning width is.

However, the two ends of the cylindrical brush wheel are respectively pivoted on the machine body and driven by the motor to rotate, when the length of the cylindrical brush wheel is longer, only the two ends of the cylindrical brush wheel are supported, so that the middle section of the cylindrical brush wheel is easy to shake in the rotating process, the rotary cutting acting force applied by the two ends and the middle section of the cylindrical brush wheel relative to the wall surface is not uniform, and different rotary cutting acting forces are generated in the cleaning track, so that the wall cleaning cleanliness is not uniform.

In order to improve the above phenomenon, if a plurality of supporting points are added to the middle section between the two ends of the cylindrical brush wheel, although the problem of shaking of the middle section of the cylindrical brush wheel can be solved, gaps which are not brushed in a cleaning track are formed due to the spacing of the supporting points when the cylindrical brush wheel brushes a wall surface, and thus, the phenomenon that the cleanliness of the wall washing is inconsistent can also be caused.

In addition, since the power transmitted to the cylindrical brush wheel by the motor gradually decreases as the length of the cylindrical brush wheel is longer, when the length of the cylindrical brush wheel is longer, that is, the cleaning width of the brush wheel to the wall surface is wider, the power transmitted from the motor to the end of the brush wheel shaft is weaker due to the influence of resistance, and the phenomenon that the cleaning effect of the double end wheel surfaces of the longer cylindrical brush wheel is inconsistent when the wall surface is cleaned is further influenced, and thus the improvement is needed.

The machine body 10 is provided with a clear water spray head 13 and a cleaning liquid spray head 14, wherein the cleaning liquid spray head 14 is located between the plurality of brush discs 20 in implementation and can spray and supply cleaning liquid to the wall surface 60 so as to facilitate the brush discs 20 to brush off dust and dirt attached to the wall surface 60; the clean water spray head 13 is located above the plurality of brush discs 20 and the cleaning solution spray head 14, and can spray and supply clean water to the wall surface 60, so that scale (including dust and cleaning solution) on the wall surface, which is brushed by the brush discs 20, can be washed away from the wall surface 60, and the cleanliness of the wall surface 60 after brushing is improved.

A plurality of exhaust fans 15 arranged in a row are arranged on one side of the machine body 10 opposite to the wall surface 60, when the exhaust fans 15 operate, suction acting force can be generated in the machine body 10 to enable the wall washer to provide negative pressure suction force relative to the wall surface 60 so as to suck scale remained in the wall surface 60 in the brushing process, and the negative pressure suction force can also push and guide a plate surface comprising the brushing plate 20 and a wheel surface of the resistance roller 30 to contact the wall surface 60 through the machine body 10 so as to improve the stability of the machine body 10 in the wall washing process and remove the scale on the wall surface; the machine body 10 is provided with a water collecting tank 16, the water collecting tank 16 is used for collecting the scale absorbed into the machine body 10 by the exhaust fan 15, the bottom of the machine body 10 is provided with a drainage pipe 17 communicated with the water collecting tank 16, so that the scale on the wall surface accumulated in the water collecting tank 16 is discharged to the outside from the drainage pipe 17.

The plurality of brush discs 20 can be arranged on the disc body 22 of the brush disc 20 in a manner that the plurality of soft brush hairs 21 extend towards the same specific direction, so that the disc surface of the brush disc 20 has the capability of flexibly pressing and contacting the wall surface 60. Herein, the specific direction is a direction perpendicular to the wall surface 60 when the wall washer is suspended from the wall surface 60.

Further, referring to fig. 1, fig. 2 and fig. 5, it is described that the plurality of brush discs 20 are pivotally disposed on a side of the machine body 10 facing the wall surface 60 in a staggered and layered configuration. Wherein, the staggered arrangement of the plurality of brush disks 20 means that the horizontal distance h between the center of one brush disk 20a and the center of the adjacent brush disk 20b of the plurality of brush disks 20 is greater than zero and smaller than the sum of the radii of the brush disk 20a and the adjacent brush disk 20b, that is, 0< h < (r1+ r 2); the layered arrangement of the plurality of brush disks 20 means that the brush disk 20a and the adjacent brush disk 20b have different heights in the direction of the cleaning locus of the wall surface 60. In this way, the cleaning locus 23a of the brush disc 20a and the cleaning locus 23b formed by the adjacent brush disc 20b on the wall surface 60 can generate partially overlapped staggered areas a (as shown in fig. 5), so as to avoid dirt gaps which are difficult to be cleaned when the wall surface 60 is cleaned between the plurality of brush discs 20, and enable the cleaning loci of the plurality of brush discs 20 to be integrated into a whole under the premise of having a larger cleaning width W. In addition, the brush disc 20a is prevented from contacting with the adjacent brush disc 20b, so that the phenomenon that the brush disc 20a and the adjacent brush disc 20b interfere with each other when rotating can be avoided.

Please refer to fig. 4, which illustrates that the rotation direction of the brush disc 20a is opposite to the rotation direction of the adjacent brush disc 20b, so that the reaction forces generated by the brush disc 20a and the adjacent brush disc 20b to the machine body 10 during rotation are opposite in direction, and thus the reaction forces generated by the two can be mutually offset, thereby improving the stability of the wall washer during brushing the wall surface 60; in an implementation, two

adjacent brush discs
