[0036] Specifically, the first driver 25 includes a motor isolation cover and a stepper motor installed in the motor isolation cover. The structure of the second driver 26 is the same as that of the first driver 25. The output shafts of the stepper motors of the first driver 25 and the second driver 26 pass through the motor isolation cover and are both installed with a driving gear 251. The first traveling wheel 17 includes a mounting frame 171, on which a mounting shaft 172 is passed, on which a roller 173 and a driven gear 174 are fixedly installed, and the driven gear 174 is meshed with the driving gear 251 of the first driver 25.

The driving gear 251 is driven to rotate by a stepper motor, and the driving gear 251 drives the driven gear 174 to rotate, thereby driving the rollers 173 to rotate, thereby driving the robot to move. The steering effect can be achieved by controlling the rotation speed of the first driver 25 and the second driver 26.

[0037] Specifically, the structures of the third driver 42 and the fourth driver 41 are the same as those of the first driver 25. The output shaft of the stepper motor of the third driver 42 is connected to the unwinding shaft 430 by transmission, and the output shaft of the stepper motor of the fourth driver 41 is connected to the winding shaft 431 by transmission. The connecting socket includes a seat body 421 and a plug 422. The plug 422 of the third driver 42 is electrically connected to the stepper motor of the third driver 42. The plug 422 of the fourth driver 41 is electrically connected to the stepper motor of the fourth driver 41. The connecting plug 24 is provided with a connecting groove 241 matching the seat body 421. The connecting groove 241 is provided with a jack matching the plug 422. The jack is electrically connected to the output end of the controller. The third driver 42 and the fourth driver 41 are electrically connected to the controller 23 by connecting the plug 422 and the jack. The operation of the stepper motors of the third driver 42 and the fourth driver 41 is controlled by the controller 23. At the same time, the plug 422 is isolated by the connecting groove 241 and the seat body 421 to prevent water from entering during use.

[0038] Specifically, two connecting posts 441 are fixedly connected to both ends of the rag belt 44, a first slot 434 is axially opened on the outer wall of the winding roller 432, a through hole 433 is opened at the bottom of the first slot 434, the through hole 433 is connected to the first slot 434, the width of the first slot 434 is smaller than the diameter of the through hole 433, the through hole 433 matches the connecting post 441, a second slot 435 is axially opened on the outer wall of the winding roller 432, the width of the second slot 435 is larger than the diameter of the through hole 433. By moving the two connecting posts 441 to the second slot 435, since the width of the second slot 435 is larger than the diameter of the through hole 433, the connecting post 441 is removed from the winding roller 432, thereby separating the rag belt 44 from the winding roller 432, making it more convenient to separate, disassemble and install the rag belt 44, so as to facilitate the replacement and cleaning of the rag belt 44.

[0039] Specifically, the belt unwinding mechanism includes a U-shaped frame 131, on which a belt unwinding roller 132 is installed, and the rag belt 44 is wound around the belt unwinding roller 132. A reserved groove 133 is opened on the U-shaped frame 131, and the rag belt 44 is supported by the belt unwinding roller 132 so that the rag belt 44 can better contact the ground, so as to better clean the ground.

[0040] Specifically, a water tank 16 is installed on the U-shaped frame 131, and disinfectant is contained in the water tank 16. A submersible pump 36 is installed in the water tank 16, and a liquid outlet pipe 361 is connected to the submersible pump 36, and an active valve 351 is installed on the liquid outlet pipe 361. A sprinkler 3 is sleeved on the outer surface of the upper shell 21, and the sprinkler 3 includes an annular pipe 31, and a liquid inlet pipe 32 is connected to the annular pipe 31. The liquid inlet pipe 32 is penetrated in the upper shell 21. A clamp 34 is installed at the bottom end of the partition 22, and the clamp 34 is sleeved on the liquid inlet pipe 32. The liquid inlet pipe 32 is fixed by the clamp 34 to prevent the liquid inlet pipe 32 from being deflected. A passive valve 352 is installed on the liquid inlet pipe 32, and the passive valve 352 is connected to the active valve 351 in a conventional manner. The passive valve 352 is connected to the active valve 351 to connect the liquid outlet pipe 361 and the liquid inlet pipe 32. A plurality of liquid spray seats 33 are installed on the annular tube 31. A liquid outlet 331 is provided in the liquid spray seat 33. The liquid outlet 331 is connected to the electromagnetic valve 332. A touch switch is installed at the end of the liquid spray seat 33. The electromagnetic valve 332 is connected in series with the touch switch and is electrically connected to the power supply. When the robot moves to a dead angle, the touch switch is triggered by collision. After the touch switch is turned on, the electromagnetic valve 332 is opened. At the same time, the submersible pump 36 is started by the controller 23 to extract the disinfectant in the water tank 16 and spray it out from the opened electromagnetic valve. The disinfectant can be sprayed at the collision site for disinfection. An atomizing nozzle 333 is installed at the outlet end of the electromagnetic valve 332. The spraying effect is improved under the action of the atomizing nozzle 333, thereby improving the sterilization effect.

[0041] Specifically, the clamp 34 includes an integrally formed fixing seat 341 and a first fixing clamp 342. The fixing seat 341 is fixedly connected to the partition 22.

The two connecting blocks 3431 are slidably inserted into the slot 3422. The second fixing clamp 342 is detachably connected to the first fixing clamp 342 through the second connecting block 3431. The second fixing clamp 343 can be separated from the first fixing clamp 342 by sliding the second fixing clamp 343, and disassembly and installation are relatively convenient.

[0042] When in use, the controller 23 controls the first driver 25 and the second driver 26, and the stepper motors of the first driver 25 and the second driver 26 drive the driving gear 251 to rotate, and the driving gear 251 drives the driven gear 174 to rotate, thereby driving the roller 173 to rotate, so as to drive the robot to move. During the movement, the floor is wiped and cleaned by the rag belt 44. When the rag belt 44 at the bottom of the unwinding roller 132 needs to be replaced, the third driver 42 drives the unwinding shaft 430 The rag belt 44 wound on the winding roller 434 of the unwinding shaft 430 is unwound by rotation, and the reel shaft 431 is driven to rotate by the fourth driver 41. The reel roller 434 on the reel shaft 431 is rotated to reel the rag belt 44 and drive the rag belt to move, and the dirty rag 44 is reeled into the sewage tank. At the same time, the felt rag belt in the clean water tank 15 is pulled out to replace the dirty rag belt 44 under the unwinding roller 132, thereby achieving the effect of replacement, which is convenient to use and does not require frequent shutdown for replacement. When the robot moves to a dead corner, the touch switch is triggered by collision, and the solenoid valve 332 is opened after the touch switch is turned on. At the same time, the controller 23 starts the submersible pump 36 to extract the disinfectant in the water storage tank 16, and the extracted disinfectant is sprayed out through the opened solenoid valve to disinfect the dead corner.

[0043] When the rag belt 44 needs to be replaced, open the lock 10 to separate the chassis 1 from the main body 2, open the clean water tank 15 and the sewage tank 14 to pull out the rag belt 44 completely, and then move the two connecting columns 441 that are not at the end to the second slot 435. Since the width of the second slot 435 is larger than the diameter of the through hole 433, the connecting column 441 is removed from the winding roller 432, thereby separating the rag belt 44 from the winding roller 432, and then install the clean rag belt 44 according to the above reverse steps.
