Title:
TELESCOPIC AND FOLDABLE BIN FOR VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2022/160434
Kind Code:
A1
Abstract:
A telescopic and foldable bin for a vacuum cleaner, comprising an inner bin (2), an outer bin (1), and a sealing member (5) arranged between the inner bin (2) and the outer bin (1). The inner cavity of the inner bin (2) is in communication with the inner cavity of the outer bin (1) to form a dust suction cavity (q). The inner bin (2) and the outer bin (1) can move relative to each other and are in sealed connection. The dust suction cavity (q) becomes larger or smaller as the inner bin (2) and the outer bin (1) are unfolded or folded relative to each other. The telescopic and foldable bin further comprises a locking member (4) which locks the inner bin (2) relative to the outer bin (1). Since the inner bin (2) and the outer bin (1) can move relative to each other and are in sealed connection, the capacity of the negative-pressure cavity can be flexibly adjusted based on actual usage requirements, and the suction ability and the efficiency are high. On the other hand, since the inner bin (2) and the outer bin (1) can be folded, the occupied space is small, and storage and transportation are convenient.
