In order to accurately control the lifting of the mopping brush 1 to the right, a lifting-to-right sensing module 9 electrically connected with a control is arranged on the first top shell 103 right above the first screw 3, as shown in fig. 4 and 8, the lifting-to-right sensing module 9 is used for sensing the lifting-to-right situation of the mopping brush 1, the lifting-to-right sensing module 9 comprises a channel 91 arranged on the top of the first top shell 103 and coaxially arranged with the screw, and an infrared emitter 92 and an infrared receiver 93 arranged in the radial direction of the channel 91, the top of the first top shell 103 is provided with a through hole corresponding to the channel 91 for the first screw 3 to pass through, the infrared emitter 92 and the infrared receiver 93 are respectively electrically connected with the controller, during the lifting process of the mopping brush 1, once the top end of the first screw 3 is lifted into the channel 91 and the infrared ray between the infrared emitter 92 and the infrared receiver 93 is cut off, the infrared receiver 93 cannot receive a signal of the infrared emitter 92, the controller receives an electric signal to indicate that the mopping brush 1 is lifted to the right, and the controller controls the driving motor 61 to stop lifting of the mopping brush 1;
and the lowering of the floor brush 1 into position is achieved by:
the outer diameter of the first screw 3 is not smaller than the outer diameter of the rotating shaft 2, and the controller senses the circuit current connected with the driving motor 61, when the mopping brush 1 descends, the first screw 3 moves downwards in the sleeve 5, the rotating shaft 2 slides in the rotating shaft mounting hole 41 of the driven gear disc 4, when the bottom end of the first screw 3 descends to the rotating shaft mounting hole 41, because the first screw 3 is not provided with a structure similar to the tangent plane 21, the first screw 3 cannot be clamped through the rotating shaft mounting hole 41, the driving resistance of the driving motor 61 is increased, the current in the circuit connected with the driving motor 61 is increased, and when the controller senses a current increase signal, the driving motor 61 is controlled to stop, so that the mopping brush 1 stops descending;
in practical application, two liftable mopping brushes of the present invention should be configured on one sweeping robot, and the two mopping brushes may be driven by independent driving motors 61 respectively according to the above structural form, but the two driving motors 61 are separately driven, which may occupy a large installation space of the sweeping robot, or one common driving motor 61 may be used to drive the two liftable mopping brushes respectively, as shown in fig. 9, so that the installation space may be reduced, it should be noted that the common driving motor 61 includes two output ends, and a transmission gear in transmission connection with the two output ends of the driving motor 61 respectively needs to be additionally provided as the driving gear 62 of the present invention, so that the synchronous rotation, ascending and descending of the two liftable mopping brushes can be realized.
The working principle is as follows: when the floor cleaning work is carried out by the floor cleaning robot provided with the liftable floor brush, if sundries which are difficult to clean are adhered to the floor, the limiting component 7 limits the sleeve 5, then the driving component 6 is used for lowering the floor brush 1, so that the pressure of the floor brush 1 on the floor is increased, after the floor brush is lowered to the proper position, the limiting component 7 limits the sleeve 5, and then the driving component 6 is used for rotating the floor brush 1 to clean the sundries;
in the process of marcing, when needing to hinder more, carry on spacingly through spacing subassembly 7 to sleeve 5 earlier, then realize dragging the rising of scrubbing brush 1 through drive assembly 6, after dragging scrubbing brush 1 and rise to the right place, can cross the barrier, continue work.
The foregoing is a further detailed description of the invention in connection with specific preferred embodiments and it is not intended to limit the invention to the specific embodiments described. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
