Abstract

A working trolley with built-in dust suction system includes a dust suction system and a trolley. Through directly assembling the dust suction system with the trolley, useless structures in the dust suction system is eliminated, so that the dust suction system can be assembled with the trolley with a more simplified structure. Through directly assembling the dust suction system with the trolley, the trolley breaks the old and stereotyped way of using, and the trolley is no longer just a carrying tool of a vacuum cleaner, thereby greatly increasing the effectiveness of usage of the trolley. On the other hand, the present invention enables a dust storage bucket of the dust suction system to have a feature of being independently dismountable, so that an operator does not need to dismount other components when replacing the dust storage bucket, thereby facilitating operation for the operator.
