Abstract
The invention provides a sealing device which is applied to a cleaner provided with a fixed impeller, a movable impeller, a motor, a fan cover, a transmission shaft and a bearing. The sealing device comprises a protective cover, wherein the protective cover is sleeved on the transmission shaft, the cross section of the protective cover is in an inversed U-shaped structure, the fixed impeller is provided with a positioning groove used for positioning the protective cover, and the protective cover and the fixed impeller are provided with matched connecting pieces. Effective insulation is achieved through effective matching of the positioning groove and the protective cover. The sealing device avoids the damage of the bearing because water enters the bearing through the fixed impeller to influence operation of the motor, and guarantees service life of the motor. The protective cover and the fixed impeller are provided with the matched connecting pieces, secondary sealing is conducted to the motor through the connecting pieces and sealing effect is ensured.
