Title:
VACUUM CLEANER AND CLEANING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2022/194274
Kind Code:
A1
Abstract:
A vacuum cleaner (100). The vacuum cleaner (100) comprises a vacuum cleaner body (1), a dust cup assembly (2) and a driving mechanism (4). The dust cup assembly (2) comprises a dust cup (21) and a cup cover (22). The cup cover (22) movably covers a dust outlet of the dust cup (21). The driving mechanism (4) comprises a telescopic member and a rotatably provided rotation member (41). The telescopic member is rotatably connected to the cup cover (22). When the rotation member (41) is in an initial state, the rotation member (41) abuts against the telescopic member so that the telescopic member is in a contracted state. When the rotation member (41) is rotated so that the rotation member (41) does not abut against the telescopic member, the telescopic member transitions from the contracted state to an extended state, so as to drive the cup cover (22) to move relative to the dust cup (21), and the cup cover (22) can be flipped so that the dust outlet is opened. The vacuum cleaner (100) can open the dust outlet of the cup cover (22) by means of rotating the rotation member (41), so that the telescopic member extends to push the cup cover (22) to move, and after the cup cover (22) is separated from the dust cup (21), the cup cover (22) can be flipped with respect to the dust cup (21), so that the cup cover (22) does not block the dust outlet, thereby facilitating cleaning of the interior of the dust cup (21) by a user.
