Automatic cleaning apparatus

Abstract

The present disclosure provides an autonomous cleaning device, including: a mobile platform, configured to move autonomously on an operation surface; and a cleaning module, disposed on the mobile platform, and including: a wet cleaning module, configured to clean at least part of the operation surface in a wet cleaning mode; a lifting structure, connected to the wet cleaning module and configured to enable the wet cleaning module to move upwards or downwards relative to the mobile platform; and a driving assembly, connected to the lifting structure and configured to provide power for lifting of the lifting structure, and/or, to provide a cleaning liquid for the wet cleaning module.

1 . An autonomous cleaning device, comprising:
 a mobile platform, configured to move autonomously on a cleaning surface; and   a cleaning module, disposed on the mobile platform and comprising:
 a wet cleaning module, configured to clean at least part of the cleaning surface in a wet cleaning mode; 
 a lifting structure, connected to the wet cleaning module and configured to enable the wet cleaning module to move upward or downward relative to the mobile platform; and 
 a driving assembly, connected to the lifting structure and configured to provide power for lifting of the lifting structure, and/or, to provide a cleaning liquid for the wet cleaning module. 
   
     
     
         2 . The autonomous cleaning device according to  claim 1 , wherein the driving assembly comprises:
 a motor, configured to provide a driving force for forward rotation and reverse rotation; and   a gear set, connected to an output shaft of the motor and configured to output the driving force for the forward rotation and the reverse rotation from the motor.   
     
     
         3 . The autonomous cleaning device according to  claim 2 , wherein the driving assembly further comprises:
 a clutch, meshed with the gear set, to provide the driving force when the clutch is in reverse engagement with the gear set, and not to provide the driving force when the clutch is in forward non-engagement with the gear set.   
     
     
         4 . The autonomous cleaning device according to  claim 3 , wherein the clutch comprises: a first clutch gear and a second clutch gear oppositely disposed, and the second clutch gear is provided with teeth arranged at an oblique angle in a counterclockwise direction, to provide the driving force when the second clutch gear is in reverse engagement with the gear set, and not to provide the driving force when the second clutch gear is in forward non-engagement with the gear set. 
     
     
         5 . The autonomous cleaning device according to  claim 4 , wherein the driving assembly further comprises:
 a cable gear, meshed with the first clutch gear to be driven by the first clutch gear to rotate.   
     
     
         6 . The autonomous cleaning device according to  claim 5 , wherein the lifting structure further comprises:
 a cable, with one end being wound around the cable gear and the other end being connected to the lifting structure to be driven by the gear set to pull up or down the lifting structure.   
     
     
         7 . The autonomous cleaning device according to  claim 5 , wherein the driving assembly further comprises:
 a pump, meshed with the gear set to be driven by the gear set to provide the cleaning liquid to the wet cleaning module.   
     
     
         8 . The autonomous cleaning device according to  claim 7 , wherein the gear set further comprises:
 a first-stage transmission gear, connected to the output shaft of the motor and configured to output the driving force from the motor;   a second-stage transmission gear, meshed with the first-stage transmission gear and configured to output the driving force from the motor to the cable gear; and   a third-stage transmission gear, meshed with the second-stage transmission gear and configured to output the driving force from the motor to the pump.   
     
     
         9 . The autonomous cleaning device according to  claim 8 , wherein the output shaft of the motor comprises an output gear, meshed with the first-stage transmission gear and configured to output the driving force from the motor. 
     
     
         10 . The autonomous cleaning device according to  claim 9 , wherein the driving assembly further comprises:
 a driving wheel, with an asymmetric structure, connected to the output shaft of the motor; and   a vibration member, connected to the driving wheel to reciprocate under asymmetric rotation of the driving wheel.
