With three direct current generators, the direct current generator for driving the omni-directional wheel, realize advance, retreat, turning, transverse moving left and right and tiltedly
To traveling mode.
The working principle of above-mentioned clean robot is as follows: the first mopping device is can be movable, when not needing the first wiping
When ground device, steering engine rotation drives swing connecting bar one to be swung up by connecting rod, and rag winding wheel is acted in swing connecting bar one
It is lower to move up, realize that the first mopping device is detached from the lift action on ground under the action of steering engine with this；When needs first
When mopping device works, steering engine stops working, and swing connecting bar one realizes that constant pressure is floated up and down, is made on rag winding wheel by torsional spring
Rag and surface to be cleaned constant pressure contact；Rag winding rotation is driven under the action of one synchronous belt of stepper motor and belt wheel
It is dynamic, it carries out replacing clean rag；
The lead screw of second mopping device rotates, and the sliding block being mounted on screw moves back and forth, and cross link is pushed to fold, into
And the stretching and contraction of pushing block are driven, the constantly release rag of rag volume two during stretching, pushing block pushes rag to go ahead, and carries out
The cleaning in short space；Rag volume two and rag winding bar realize the replacement of rag, under the action of the rotation of rag winding bar,
Clean rag replaces dirty rag；When pushing block is withdrawn, rag winding bar starts to rotate under the action of stepper motor, will stretch
Rag rollback out；
Water supply liquid-supplying system can provide proper amount of clear water and appropriate clear to described two mopping devices by hose and spray head
Different wiping ground modes may be implemented in washing lotion, such robot, if xerotripsis mode, clear water wiping mode, cleaning solution wipe mode,
Clear water or cleaning solution fountain height can also be selected according to surface clean level to be cleaned；
The direction of travel of clean robot is controlled by adjusting the revolving speed of three direct current generators, since three omni-directional wheels can
To there is different velocity composites, so the basic walking manner such as advance, retreat and turn not only may be implemented in main body, it can also be real
Existing transverse moving left and right and slanting traveling mode carry main body by three omni-directional wheels in this way and realize freer convenient movement.
The invention has the benefit that on the one hand, clean robot can independently replace clean rag, and this avoid length
The problem of time only uses one piece of rag, improves cleannes, while also avoiding artificial frequently replacement rag, cleaning rag.
On the other hand, wiping ground is carried out using two kinds of mopping devices, when water supply liquid-supplying system does not work, the first mopping device be may be implemented
Xerotripsis, while the second mopping device stops working, and saves clean rag usage amount；When water supply liquid-supplying system works, first wipes ground
Preliminary wet rubbing may be implemented in device, and xerotripsis may be implemented in the second mopping device, clear by the first mopping device to realize with this
The cleannes and aridity on clean surface.Constant pressure lifting and lift action may be implemented in first mopping device, and constant pressure lifting action can
So that rag is bonded with ground always, keep cleaning effect more preferable；When lift action can make the first mopping device not work and ground
Emaciated face is from effectively preventing under wet rubbing mode to the contact for a long time of such as timber floor and the phenomenon that damage floor.
