Please select the most similar patent number from A, B, C and D. Which number is?
Disclosed is a rubbish-bin-type vacuum cleaner, comprising a vacuum cleaning mechanism, a rubbish storage mechanism (10) and a top cover (1). The vacuum cleaning mechanism is detachably connected above the rubbish storage mechanism (10), and the top cover (1) is movably connected to the vacuum cleaning mechanism. The vacuum cleaning mechanism comprises a clamping assembly (5) and a vacuum cleaning assembly, which are both arranged above a hollow box body. The vacuum cleaning assembly comprises a vacuum cleaning electric motor (4), a vacuum cleaning pipeline connected to the vacuum cleaning electric motor (4), an exhaust pipeline connected to the vacuum cleaning electric motor (4), and an active separation device arranged inside the exhaust pipeline. A through hole in communication with the rubbish storage mechanism (10) is provided inside the clamping assembly (5), the through hole being used for having rubbish pass therethrough and then the rubbish being stored in the rubbish storage mechanism (10). The top cover (1) is used for sealing the through hole. The rubbish-bin-type vacuum cleaner can be moved at anytime and anywhere as required to facilitate rubbish collection, is convenient to store when not in use, does not occupy space in a house, and does not easily affect indoor aesthetics.
A: A dust bin (7) and a vacuum cleaner assembly having the dust bin (7). The dust bin (7) comprises a dust collection chamber (71), a dust inlet (72) detachably connected to a vacuum cleaning device, and a sealing structure for enabling sealing between the vacuum cleaning device and the dust bin (7). A hand-held vacuum cleaner (100) has a dust outlet (14) capable of engaging with the dust inlet (72). The vacuum cleaner assembly comprises a vacuum cleaning device and a dust bin (7) detachably connected to the vacuum cleaning device. The vacuum cleaning device has a housing (3) and a dust cup assembly (1) connected to the housing (3). The dust cup assembly (1) comprises a cup (11) and a filtering device (13) disposed in the cup (11). The detachable multipurpose dust bin (7) flexibly increases the capacity of a vacuum cleaner for containing dust.
B: A garbage can, comprising a can body (1). A top cover assembly (2) is provided on the top surface of the can body (1). The top cover assembly (2) comprises a large flap (21) hingedly connected to the can body (1). A garbage feeding port (21b) and a garbage bag box storage zone (21c) located around the garbage feeding port (21b) are formed on the large flap (21). A garbage bag cutting mechanism (5) is mounted in the can body (1), and is used for cutting and separating a garbage bag part containing the garbage from a garbage bag body.
C: A vacuum cleaner assembly comprises: a vacuum cleaning device and a dust bin for use with the vacuum cleaning device and for collecting the dirt sucked in by the vacuum cleaning device. The vacuum cleaner assembly having a first working mode and a second working mode; in the first working mode, the vacuum cleaning device is not sealingly engaged with the dust bin and operates independently to perform both vacuum cleaning and dust collection, and in the second working mode, the vacuum cleaning device is engaged with the dust bin and only performs vacuum cleaning, while the dust bin is responsible for dust collection. With a dust bin detachable from a vacuum cleaning device, the vacuum cleaner assembly of the present invention can flexibly increase the capacity of the vacuum cleaner for containing dust. The dust bin has a simple structure and is compact in structure when engaged with a vacuum cleaning device and thus only occupies a small space, thereby meeting the cleaning needs for scenarios of different amount of dirt.
D: A dust collection device comprises a cover assembly (1), a partition support (4), a dust collection component (2) and a separation mechanism (3) used to separate trash from a fluid. The cover assembly (1) is connected to the dust collection component (2). An installation compartment is formed between the cover assembly (1) and the dust collection component (2). The separation mechanism (3) and the partition support (4) are positioned in the installation compartment. The separation mechanism (3) is connected to the partition support (4). The partition support (4) divides the installation compartment into an electric motor accommodation compartment (11) and a dust cup compartment (21). The separation mechanism (3) comprises a separation driving assembly (31) and a centrifugal separator (32). The separation driving assembly (31) is positioned in the electric motor accommodation compartment (11). The centrifugal separator (32) is positioned in the dust cup compartment (21). The separation driving assembly (31) is connected to the centrifugal separator (32). The separation driving assembly (31) can drive the centrifugal separator (32) to make rotational movement. The dust collection device uses the separation driving assembly (31) to actively drive the centrifugal separator (32), such that rotation of the centrifugal separator (32) reaches a preset rotation speed, and then a fluid is drawn in under the action of suction of a vacuum cleaner main body, thereby effectively facilitating separation of dust from the fluid.
