| 发明名称 | Filter assembly for a vacuum cleaning appliance | ||
| 摘要 | A vacuum cleaning appliance includes a filter housing having at least one air inlet for receiving an air flow, a filter assembly removably locatable within the filter housing for removing dirt from the air flow, and a duct for receiving the air flow exhausted from the filter assembly. The filter assembly includes a filter body, a filter mounted on the filter body, and a spring-loaded coupling member moveable relative to the filter body for engaging the duct. The coupling member includes an air outlet through which the air flow is exhausted from the filter assembly. A convoluted sealing member forms a seal between the filter body and the coupling member while allowing relative movement therebetween as the coupling member engages the duct. | ||
