Structure of pool cleaning robot and pool cleaning robot

Abstract

The present disclosure relates to a structure of pool cleaning robot, including a body, at least one driving unit arranged at one end of the body, a propeller arranged at the output end of the driving unit, and anti-vortex fins arranged on the propeller. The present disclosure uses propeller propulsion, and anti-vortex fins are arranged at the rear end of the propeller, which can eliminate the hub vortex cavitation generated by the propeller to reduce the pressure at the rear of the propeller and further reduce the induced resistance caused by the hub vortex cavitation, thereby improving the propulsion efficiency of the propeller.
