In this embodiment, the left and right ends of the collecting box 340 are provided with two mounting cavities 341 for mounting the triggering mechanism 330, the button 331 is provided with two buttons and respectively disposed in the two mounting cavities 341, the button 331 can move up and down relative to the collecting box 340, and the top end of the button 331 extends out of the collecting box 340.

It will be understood that when the cleaning robot 10 enters the base station 20, at least a part of the walking wheels 121 are inserted into the positioning grooves 223, and at this time, the front end of the body of the cleaning robot 10 moves downward relative to the washing tray 220 and presses the bottom shell of the cleaning robot 10 against the button 331, which is preferably a mounting bracket connecting section or a mounting housing of the rolling brush 110 against the button 331 in this embodiment.

It is understood that the return spring may include a compression spring 335 provided at the bottom end of the button 331 and/or a torsion spring 334 provided at both ends of the worm gear 333 in the base 310. When the return spring is a compression spring 335 disposed at the bottom end of the button 331, the compression spring 335 drives the button 331 to move upward after the button 331 is released, the worm wheel 333 rotates under the action of the worm portion 332, and drives the base 310 to swing and return. When the return spring is a torsion spring 334 arranged at both ends of the base, the torsion spring 334 drives the base to swing and return after the button 331 is released, and simultaneously drives the worm wheel 333 to rotate and drives the button to move upwards.

The torsion springs 334 are provided with two torsion springs and are respectively sleeved on the rotation shafts at the two ends of the base 310, the base 310 swings around the rotation shafts, the worm wheel 333 is sleeved on one torsion pin of the torsion springs 334 and is meshed with the worm portion 332, and the other torsion pin of the torsion springs 334 is abutted against the base 310. Preferably, two torsion springs 334 are fixedly connected to the torsion legs of the base 310. The compression spring 335 is sleeved on the lower portion of the button 331, the bottom end of the compression spring 335 abuts against the inner bottom wall of the installation cavity 341 to achieve positioning, and the top end of the compression spring abuts against the protrusion on the circumferential outer wall of the button 331 to achieve contact with the button 331. When the cleaning robot 10 stops at the base station 20, the button 331 is pressed to enable the button 331 to be stressed and move downwards, the compression spring 335 is stressed and compressed, the button 331 moving downwards drives the torsion pin of the torsion spring 334 to move through the engagement between the worm part 332 and the worm wheel 333, so that the torsion spring 334 tightens the base 310 and drives the base 310 to swing upwards from the storage state to the extension state, the comb teeth 320 and the blade 370 are in interference contact with the rolling brush 110, and at the moment, the torsion spring 334 is in the torsion state. When the cleaning robot 10 leaves the base station 20, on one hand, the compression spring 335 that recovers deformation drives the button 331 to move upward and return, and the button 331 that moves upward drives the torsion leg of the torsion spring 334 to rotate toward the direction that recovers deformation through the engagement between the worm part 332 and the worm wheel 333, and drives the base 310 to swing downward from the extended state and return to the storage state, so that the comb teeth 320 and the blades 370 are stored in the storage cavity 350. On the other hand, the torsion spring 334 restores to deform to drive the base 310 to return to the storage state, and the torsion pin of the torsion spring 334 rotates towards the deformed line of defense and drives the worm wheel 333 to rotate, and drives the button 331 to move upwards through the worm part 332 to return. The combination ensures the reliability of the simultaneous resetting of the base 310 and the button 331.
