Rotation.Towards attached drawing, it is assumed that the limited post 811 on the right being arranged on driving lever 813 and movable plate 810 at this time connects, tension spring
818 are in tensional state, and pulling force drives driving lever 813 closely to connect with the limited post 811 on right side, L shape shifting part 814 is driven to drive
The arc notch 823 of outside fixture block 822 and the second lead screw 829 are cooperatively connected, since the second lead screw 829 is with arc notch 823
Inside and outside silk is threadedly coupled, so the rotation of the second lead screw 829 can drive sliding block 807 to move right along the second slideway 805, until dialling
Bar 813 is contacted with the locating piece 806 on right side, continues to move right, due to the blocking of locating piece 806, in the pulling force of tension spring 818
Under, driving lever 813 is slowly tilted to the left, until the pulling force of tension spring 818 can drive driving lever 813 to invert, driving lever in a flash
813 are in close contact with the limited post 811 in left side, L shape shifting part 814 drive inside fixture block 822 arc notch 823 and first
Thick stick 828 is cooperatively connected, since the first lead screw 828 is that inside and outside silk is threadedly coupled with arc notch 823, the rotation of the first lead screw 828
Sliding block 807 is driven to move downward along the first slideway 804, until driving lever 813 is contacted with the locating piece 806 in left side, continuation is transported to the left
Dynamic, due to the blocking of locating piece 806, under the pulling force of tension spring 818, driving lever 813 is slowly tilted to the right, until drawing in a flash
The pulling force of spring 818 can drive driving lever 813 to invert, and driving lever 813 closely connect with the limited post 811 on right side, L shape shifting part
814 drive the arc notch 823 of outside fixture block 822 and the second lead screw 829 to be cooperatively connected, since the second lead screw 829 is lacked with arc
Mouth 823 is that inside and outside silk is threadedly coupled, so the rotation of the second lead screw 829 can drive sliding block 807 to be transported to the right along the first slideway 804
Dynamic ... above procedure constantly recycles, and realizes the reciprocating motion of sliding block 807 or so, then drives wiper mechanism 7 left to billboard 1
The cleaning of right circulation.
The control switch for opening micromotor 708 makes micromotor 708 work, and the second crank 707 is driven to rotate, and drives
The movement of first crank 706 realizes the cleaning recycled to about 1 billboard so that clean plate 704 be made to move back and forth along square hole 702.
In order to improve cleaning effect, before the work of wiper mechanism 7, water pump 42 is first turned on, sparge pipe 5 is to billboard 1
It is wet to carry out sprinkling, it is sprayed to switch off the pump 42.
Driving motor 824, driving gear 825, the first driven gear 826, the second driven gear used in the present invention
827, the first lead screw 828, the second lead screw 829, water pump 42, control switch, spray head 6, micromotor 708 and water pump 42 and water spray
Pipe 5, water tank 41 connection type be the prior art, be no longer described in detail.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
