Vacuum cleaner main unit

Abstract

The present disclosure provides a vacuum cleaner main unit which is firstly provided with a mounting seat, a battery, a motor, and a dust cup. The battery, the motor, and the dust cup are all mounted on the mounting seat; the mounting seat is provided with a handle and an air inlet pipe; the air inlet pipe is fixedly connected to the handle; the motor is detachably mounted on the mounting seat; the position of the motor corresponds to the position of the handle; the battery is detachably mounted on a first end part of the motor; the dust cup is detachably mounted on a second end part of the motor; and the position of the dust cup corresponds to the position of the air inlet pipe. Compared to the existing art, the present disclosure has the advantages that the suction loss of a vacuum cleaner is reduced, and the suction power is increased, so that the weight of the vacuum cleaner is distributed more uniformly, and it is more labor-saving when the vacuum cleaner is held in a hand to do cleaning.
