Abstract

A grinder is provided with a dust collecting structure comprising a base, a motor, a dust collecting cover, a blast wheel, a grinding body, and a dust collecting canister. The base is provided with a port. The motor is mounted on the base. The dust collecting cover has an open end and an opening corresponding to the port of the base. The blast wheel is disposed in the dust collecting cover such that a channel is formed between the blast wheel and the dust collecting cover and is in communication with the port of the base. The blast wheel is driven by the motor to turn. The grinding body is disposed at the outer side of the blast wheel and is driven by the motor to grind a workpiece. The dust collecting canister is in communication with the port of the base for collecting the dust from the grinding body via the channel.

What is claimed is:  
     
         1 . A dust collecting structure of a grinder, comprising:
