The invention discloses a 
wireless charging function-based energy-saving sweeping 
robot. The 
wireless charging function-based energy-saving sweeping 
robot comprises a 
robot body, a power supply battery, a 
master controller and a roller driving mechanism and also comprises a timing module, an electric quantity detection module, a navigation positioning module, a 
wireless receiving coil and a charging conversion circuit, wherein the electric quantity detection module is used for detecting the power supply battery to obtain a remaining electric quantity value, the navigation positioning module is used for positioning a current position coordinate of the robot body and performing navigation according to a navigation 
route, the 
master controller is used for calculating to obtain the navigation 
route when the remaining electric quantity value is smaller than a preset remaining electric quantity threshold and generating a driving 
signal and a trigger 
signal according to the navigation 
route, the roller driving mechanism is used for driving the robot body to travel according to the navigation route and building 
inductance coupling with an external wireless charging base to receive a current, and the charging conversion circuit is used for converting the current received by the wireless receiving coil to a 
direct current and inputting the 
direct current to the power supply battery for storage. By the wireless charging function-based energy-saving sweeping robot, the automatic charging function of the sweeping robot is achieved, the charging efficiency is improved, so that the charging mode is flexible, and the practicability is improved.
