Abstract
A filtering device of a dust collector (i.e, vacuum cleaner) comprises a filter, a rack, an end cap, and a fixed portion. The filter has filter paper, a sealing member, and the end cap, the filter paper being disposed between the end cap and the sealing member. An end hole penetrating the end cap is provided on the end cap, and the filter is mounted on the rack. A center post is provided on the rack, and the center post runs through the end hole. A locking portion is disposed between the end cap and the fixed portion, and the locking portion firmly locks the center post when the fixed portion is fastened to the end cap. The filtering device of a dust collector does not have an elastic interference fit during implementation, and is more reliably secured; and therefore, it does not accidentally fall off during use.
