It can be seen that when the leftmost cleaning rod set 2 (movable rod) is limited at the corner, the bristles and the brush head seat 23 are limited to compress the limiting spring 24, the limiting spring 24 is compressed and deformed to increase the pressure of the pressure sensor 22, thereby causing the pressure change of the whole cleaning rod 2, and correspondingly, the driving device 3 performs driving in response to the pressure change of the pressure sensor 22, so as to drive the leftmost cleaning rod set 2 to move back. With reference to the figures, the return distance of the leftmost set of cleaning bars 2 is: when the left second group of cleaning rods 2 is limited at the corner, the front ends of the leftmost group of cleaning rods 2 just contact the target inner wall surface behind the corner. When the dead lever on mounting substrate 1 removed to the corner, change mounting substrate 1's moving direction, mounting substrate 1 moved down to keeping away from the corner this moment, in the in-process that moves down, be located the interior wall of clean pole 2 (movable rod) of dead lever right side and break away from the target, therefore the pressurized sudden change of pressure sensors 22 that corresponds is 0, drive arrangement 3 carries out the drive in response to pressure sensors 22's pressure change this moment, with this clean pole 2 of ordering about dead lever right side stretch out to clean front end, and with the interior wall contact of target, accomplish the deformation cleanness of corner.

With respect to the two embodiments described above, in a specific embodiment of the present invention, regarding the driving of the cleaning rod 2: one side of setting up the movable rod is continuous tooth's socket structure, sets up drive arrangement 3 and includes N rotatable fluted roller 31, and fluted roller 31 and the tooth's socket side one-to-one meshing of movable rod.
