Patent Images
1. A suction cleaner comprising:
- a housing, an end of the housing having a dust-suction opening;
a holding part connected to the housing;
an impeller module located inside the housing, a channel being configured between the dust-suction opening and the impeller module;
a first sensing device configured on the holding part;
a second sensing device configured around the dust-suction opening;
a third sensing device configured in the channel; and
a controller electrically connected to the impeller module, the first sensing device, the second sensing device, and the third sensing device, whereinthe controller drives the impeller module to rotate at a first rotation rate based on the sensing condition of the first sensing device, and the suction cleaner is in a ready-to-work state when the holding part of the suction cleaner is being contacted;
the controller drives the impeller module to rotate at a second rotation rate based on the sensing condition of the second sensing device, and the suction cleaner is in a normal dust-suction state when the suction cleaner comes close to or in contact with a surface of an object;
the controller drives the impeller module to continuously rotate at the second rotation rate based on the sensing condition of the third sensing device, and the suction cleaner maintains the normal dust-suction state when the suction cleaner collects a relatively small quantity of dust particles or debris; and
the controller drives the impeller module to rotate at a third rotation rate based on the sensing condition of the third sensing device, and the suction cleaner is in a maximum dust-suction state when the suction cleaner collects a relatively large quantity of dust particles or debris.

Abstract
A suction cleaner and an operation method thereof are provided. The suction cleaner includes a housing, a holding part, an impeller module, at least one sensing device, and a controller. An end of the housing has a dust-suction opening. The impeller module is located inside the housing, and a channel is located between the impeller module and the dust-suction opening. The controller is electrically connected to the sensing device to drive and adjust the rotation rate and the suction force of the impeller module, and thus the power consumption of the suction cleaner can be reduced.
