Abstract
A vacuum device includes a device body, a dust-collecting box, a fan and a detection unit. The device body further has a duct outlet and a fan outlet. The dust-collecting box located inside the device body is spatially connected to the duct outlet. The fan located inside the device body at a place beside the dust-collecting box is spatially connected to the fan outlet. The detection unit located close to the fan outlet further includes a sensor and a rotation assembly; in which the sensor further has an infrared-emitting component and an infrared-receiving component, the rotation assembly is able to pass rotationally through a space between the infrared-emitting component and the infrared-receiving component, and the infrared-emitting component is to emit an infrared to the infrared-receiving component for detecting the rotation assembly.
