Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It please refers to Fig.1 to Fig. 7, the present invention provides a kind of technical solution：The cleaning dust-extraction unit of sweeping robot, shell
101, motor 200 and clearing apparatus, wherein controller and power supply are provided in shell 101, power supply is connect with controller point,
Controller controls entire sweeping robot movement.Clearing apparatus includes brush 300, and brush 300 is for cleaning ground, electricity
Machine 200 is installed in shell 101, and there is connecting shaft 310, transmission shaft 210 and the connecting shaft 310 of motor 200 to pass through company for brush 300
Outbound 113 connects simultaneously for driving brush 300 to rotate, specifically, connecting shaft 310 is vertically arranged, the also edge of transmission shaft 210
Vertical direction is arranged, and motor 200 controls start and stop by controller and controls 200 forward or reverse of motor.
Specifically, connecting pin 113 includes plunger 430, shell 427 and spring 424, the one end open 421 of shell 427 is opened
Mouth 421 bends inwards to form flange 422, second part 432 and first part 431 of the plunger 430 including interconnection, first
431 are divided to be slidably arranged in shell 427,424 one end of spring connects the bottom of shell 427, and the other end connects first part 431 simultaneously
First part 431 is pressed on flange 422.
Second part 432 stretches out opening 421, and the one end of second part 432 far from first part 431 is provided with arcwall face
433, connecting shaft 310 and transmission shaft 210 are respectively provided with connecting shaft connecting pin 312 and transmission shaft connecting pin for interconnection
201, the rotation of transmission shaft connecting pin 201 is set in connecting shaft connecting pin 312；Connecting shaft connecting pin 312 is provided with card slot 313,
Shell 427 is embedded in card slot 313, and transmission shaft connecting pin 201 is provided with slot 202, and second part 432 is embedded in slot 202
Interior, the direction that wherein first part 431 is slided is vertical with the extending direction of transmission shaft 210.
Specifically, the longitudinal cross-section of connecting shaft connecting pin 312 is crescent, the longitudinal cross-section of transmission shaft connecting pin 201 is
Circle, transmission shaft connecting pin 201 are set in connecting shaft connecting pin 312；Arcwall face 433 is hemisphere face, and slot 202 is hemispherical
Slot.
By the change of the rotation direction of motor 200, brush 300 may be implemented, and reciprocal brush is swept back and forth, and then by ground
Stain cleans up, during 200 deflecting back and forth of motor, since the first part 431 in connecting pin 113 can edge
It is slided in shell 427, in this way when 200 deflecting of motor, although connecting shaft 310 can continue due to inertia along former rotation direction
Rotation, the second part 432 of connecting pin 113 is sheared at this time, and second part 432 can be pressurized compressed spring 424, due to second
It is hemispherical to divide 432, is become smaller from close to 424 one end of spring to far from 424 one end of spring, during its compressed spring 424,
Connecting shaft 310 can continue to move sub-fraction distance along former rotation direction, play cushioning effect, be unlikely to prominent in motor 200
It is contacted firmly with transmission shaft 210 due to effect of inertia during right deflecting, connecting shaft 310 or transmission shaft 210 is caused to damage.Even if electric
Machine 200 carries out thousands of secondary deflectings, will not damage connecting shaft 310, at the same 300 mode of brush of this deflecting back and forth for
The scavenging effect of stain is more preferable for the elimination effect of stain compared to traditional single direction brush 300.
As the preferred embodiment of the present invention, compression spring 440 is provided in card slot 313, compression spring 440 is along connecting shaft 310
Axial setting, i.e., it is vertical with the glide direction of first part 431.One end of compression spring 440 resists shell 427, and the other end resists card
The wall of 210 side of separate transmission shaft of slot 313, refering to Fig. 4, the width of card slot 313 is bigger compared with the width of shell 427, to accommodate
Compression spring 440, the end face of connecting shaft 310 have gap 320 with the end face of transmission shaft 210.The advantages of this arrangement are as follows working as ground
When the spot of part is thicker, in cleaning, connecting shaft 310 can have certain displacement empty to 210 direction of transmission shaft for brush 300
Between, the bristle in cleaning of brush 300 will not be made to deform.
Meanwhile in the present embodiment, it is additionally provided with detector 230, detector 230 is set in gap 320 and for detecting
The width in gap 320, is provided with traveling controller in shell 101, wherein a part for traveling controller device in order to control, walking control
Device processed is electrically connected with detector 230.
Detector 230 is dial gauge, and the end of probe of dial gauge resists the end face of connecting shaft 310 and for measuring connecting shaft
310 displacement is equipped with traveling wheel 102 on shell 101, and traveling wheel 102 is electrically connected with traveling controller and by traveling controller
Control.When sweeping robot is in first beginning and end working condition, traveling wheel 102 is concordant with the end face of brush 300, when machine of sweeping the floor
Man-hour meets the stain on ground, and since spot has certain thickness, compression spring 440 is compressed at this time, connecting shaft 310
It is slided towards 210 direction of transmission shaft, 320 width of gap becomes smaller, and detector 230 detects obtained 320 change width of gap and is
The displacement of connecting shaft 310.Controller knows connecting shaft 310 towards 210 displacement of transmission shaft at this time, illustrates that ground has firm at this time
Spot do not clean out, then control 102 stopping of traveling wheel action, sweeping robot original place clean, motor 200 is according to certain
Time interval（Such as 5s）Deflecting, the brush 300 at stain back and forth back and forth, until spot is worn away, compression spring 440 at this time
Restore deformation, connecting shaft 310 resets, and 320 width of gap that detector 230 obtains replys original state, and controller judges accordingly
Spot has cleaned up, and controls the continuation of traveling wheel 102 and clean forward.
By above-mentioned setting, sweeping robot of the invention can effectively clear up the stain on ground, cleaning effect
More preferably.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
