When the first preferred embodiment of the automatic machine for cleaning wallboards in accordance with the present invention is in operation, the cleaning water flows into the water guide pipes 11 of the long axial tracks 10. The main driving devices 23 or the auxiliary driving devices 71 are switched on to drive all of the sliding engine bases 20 to simultaneously slide along the long axial tracks 10. As the power extending object 54A retracts, the bristles 411A of the at least one long axial brush 40A abut the wallboard 90. The at least one vibrator 42A vibrates, so the at least one long axial brush 40A vibrates as well. Since the at least one long axial brush 40A is rotatable, the at least one long axial brush 40A rolls across the protrusions of the wallboard 90 with lowered resistance and easily cleans the wallboard 90. The mounting wings 214 of the sliding brackets 21 simultaneously push the long axial magnet bodies 151 to slide along the magnet guiding recesses 15. The long axial magnet bodies 151 and the magnets 32 of the magnetic valves 30 attract each other. Thus, when the sliding engine bases 20 slide by, the magnets 32 are attracted by the long axial magnet bodies 151 and loosen the waterproof gaskets 34 so the through holes 341 of the waterproof gaskets 34 are revealed. Consequently, the cleaning water in the water guide pipes 11 of the long axial tracks 10 is drained from the magnetic valves 30 and flows over the wallboard 90. When the sliding engine bases 20 as well as the long axial magnet bodies 151 depart from the magnetic valves 30, the springs 33 of the magnetic valves 30 push the magnets 32 and the magnetic plates 35 of the magnetic valves 30 attract the magnets 32, so the magnets 32 seal the through holes 341 of the waterproof gaskets 34 to prevent the cleaning water in the water guide pipes 11 from being drained. Moreover, water drops left on the wallboard 90 is cleaned away with the sliding engine bases 20 sliding across and the bristles 411A of the at least one long axial brush 40A abutting the wallboards 90 such that the vibrators 42A vibrate the at least one long axial brush 40A. Additionally, after the wallboard 90 has been cleaned, the blower 63A may be switched on to guide air with high pressure into the vent channel 62A of the at least one protective cover plate 60A. The air further flows through the through holes 611A of the partition 61A to dry the water drops.
In the above-mentioned automatic machine, the long axial tracks 10 may be made of materials with antioxidant properties and are orderly mounted on the wallboard 90. When the automatic machine is not in operation, the at least one long axial brush 40A is put aside of the building and the power extending objects 54A protrude and push the brush supporting bases 50A. Thus, the bristles 411A of the at least one long axial brush 41A are moved off the wallboard 90 and will not be easily deformed. The at least one protective cover plate 60A protects the at least one long axial brush 40A and beautifies appearance of the automatic machine.

The magnetic valves 30, the at least two long axial tracks 10 and the at least two sliding engine bases 20 of the second preferred embodiment of the automatic machine are the same as the magnetic valves 30, the at least two long axial tracks 10 and the at least two sliding engine bases 20 of the first preferred embodiment of the automatic machine.

Each of the at least one brush bracket 40B is elongated and has a brush 41B, multiple pivot seats 43B and a vibrator 42B. The brush 41B is mounted on an outer surface of the brush bracket 40B and is changeable. The pivot seats 43 are separately mounted on an inner surface of the brush bracket 40B. As shown in the drawing, the brush bracket 40B has two pairs of pivot seats 43 respectively disposed adjacent to a top and a bottom of the brush bracket 40B. The vibrator 42B is mounted on the brush bracket 40B.
Each of the at least two sliding brush bases 50B is a rectangular frame, is capable of being received in the bracket protective cover plate 60B, and has two slides 52B, two fastening seats 51B, a pulling element 53B, multiple pivot seats 54B, multiple connecting rods 55B and a power extending object 44B. The slides 52B are disposed on an inner surface of the sliding brush base 50B, respectively disposed adjacent to two opposite side edges of the sliding brush base 50B and are respectively mounted slidably on the elongated sliding tracks 64B of the bracket protective cover plate 60B. The fastening seats 51B are disposed on the inner surface of the sliding brush base 50B and are respectively disposed adjacent to an upper edge and a lower edge of the sliding brush base 50B. The pulling element 53B may be a chain, a belt or a cable, is mounted around the transmission roller 66B and the guide roller 67B, and has two ends respectively connected to the fastening seats 51B. The pivot seats 54B of the sliding brush base 50B are separately mounted on an outer surface of the sliding brush base 50B and respectively correspond to the pivot seats 43B of the brush bracket 40B. Each connecting rod 55B is connected to one of the pivot seats 54B of the sliding brush base 50B and one of the pivot seats 43B of the brush bracket 40B that correspond to each other. Thus, the brush bracket 40B parallelly slides up and down relative to the sliding brush base 50B. The power extending object 44B is pivotally connected to the brush bracket 40B and the sliding brush base 50B and selectively drives the brush bracket 40B to slide up and down, and forward and backward.

The second preferred embodiment of the automatic machine is controlled by a controlling mechanism. Preferably, the controlling mechanism may be a programmed numerical control to selectively wash a partial of the wallboard 90. Take washing the glass window 91 of the wallboard 90 for example. Operating processes of the second preferred embodiment of the automatic machine are input into the programmed numerical control. At first, the main driving devices 23 or the auxiliary driving devices 71 are switched on to drive all of the sliding engine bases 20 to simultaneously slide transversely along the long axial tracks 10 to correspond to the glass windows 91. Then, the driving apparatuses 65B of the bracket protective cover plates 60B drive the sliding brush bases 50B to slide longitudinally to correspond to specific positions of the glass windows 91. When the sliding engine bases 20 and the sliding brush bases 50B correspond to the glass windows 91, the programmed numerical control controls cleaning water from tap water or pumps to flow into the water guide pipes 11 of the long axial tracks 10. The long axial magnet bodies 151 and the magnets 32 of the magnetic valves 30 attract each other. Thus, the waterproof gaskets 34 are loosened from the magnets 32 of the magnetic valve 30 and the through holes 341 of the waterproof gasket 34 are revealed. Consequently, the cleaning water in the water guide pipes 11 of the long axial tracks 10 is drained from the magnetic valves 30 when the sliding engine bases 20 slide by.
In the second preferred embodiment of the automatic machine, each of the magnetic valves 30 further has a bent pipe 300B. The bent pipe 300B is connected to an outlet of the magnetic valve 30, is bending downward and has an outlet corresponding to the water collecting receptacle 68B of the bracket protective cover plate 60B. Therefore, the cleaning water drained from the water guide pipe 11 of the long axial track 10 further flows into the water collecting receptacle 68B below the magnetic valve 30, and flows through the guiding tube to flow into the water storage receptacle 69B. When the water storage receptacle 69B receives enough cleaning water, the programmed numerical control activates the power extending object 44B to drive the brush bracket 40B to slide toward the glass window 91, then activates the pump mounted on the water storage receptacle 69B to pump the cleaning water to the glass window 91, and activates the vibrator 42B to vibrate the brush bracket 40B to clean the glass window 91.
At the same time, the main driving devices 23 or the auxiliary driving devices 71 drive the sliding engine bases 20 to slide transversely, and the driving apparatuses 65B drive the sliding brush bases 50B to slide longitudinally to allow the sliding engine bases 20 and the sliding brush bases 50B to slide within corresponding glass windows 91 and to clean the corresponding glass windows 91. After the glass windows 91 have been cleaned, the blower 63B is switched on to dry the water drop on the glass windows 91. Moreover, the power extending objects 44B retract the brush brackets 40B and the brush brackets 40B depart from the glass windows 91. Then, the sliding engine bases 20, the bracket protective cover plates 60B, the brush brackets 40B and the sliding brush bases 50B slide along the long axial tracks 10 to clean other glass windows 91 or slide back to and are stored at a side of the building.
In the above-mentioned automatic machine, the long axial tracks 10 may be made of materials with antioxidant properties and are orderly mounted on the wallboard 90. When the automatic machine is not in operation, the brush brackets 40B are put aside of the building and the power extending objects 44B retract the brush brackets 40B. Thus, the brushes 41B of the brush brackets 40B are moved off the wallboard 90 and will not be easily deformed. The bracket protective cover plate 60B protects the brush brackets 40B and beautifies appearance of the automatic machine.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
