The splashing of debris poses a safety hazard and is also more troublesome to clean. Existing grinding machines have shortcomings in terms of closed dust prevention and debris collection and treatment, and it is difficult to meet the needs of environmental protection, safety and convenient cleaning.

[0003] CN110465837A discloses an electric grinder for preventing debris from splashing, comprising a base. A support column is fixed to the top of the support column by bolts near the middle. A housing is fixed to the top of the support column by bolts. The interior of the housing is a hollow cavity. A motor is fixed to the left and right inner walls of the housing by bolts. The output shaft end of the motor is coaxially connected to a rotating shaft. A grinding wheel is fixed to the circumferential outer wall of the rotating shaft by bolts. Connecting rings are welded to the left and right outer walls of the housing. A storage cavity is defined within the base. A rectangular opening is defined on the front surface of the base.
