摘要： A vacuum appliance is disclosed, comprising a collection canister having a lid and a powerhead housing a motor and impeller assembly for establishing vacuum pressure within said canister. The powerhead is removably secured to the lid of the collection canister, such that the powerhead can be removed from the lid and separately used as a blower. Self-actuationg latching devices are provided for removably securing the powerhead to the lid. In one embodiment, the latching device is a unitary, multi-segmented structure having a spring biasing member and a retaining member formed integrally therewith. A journal formed integrally with the latching device is adapted to be received in a bearing defined in a latch socket on the lid, such that the latching device is allowed to pivot with respect to the lid. The spring biasing member functions to bias the latching device to a home pivot position, such that the latching device automatically engages the powerhead when it is lowered onto the lid. In another embodiment, the latching device is cantilevered structure having a spring biasing member formed integrally therewith.
