Referring to fig. 4, in some possible embodiments, the collection cassette 25 is removably coupled to the support 21.

This enables the collection box 25 to be removed from the holder 21 and cleaned or replaced for maintenance.

Further, a filter (not shown) is provided at a place where the collecting box 25 communicates with the negative pressure generating device 24.

Thus, the dirt is filtered by the filter to stay in the collecting box 25, thereby preventing damage to the negative pressure generating device 24.

In some possible embodiments, the filter is removably associated with the collection box 25 or with the support 21.

This enables the filter to be removed from the collection box 25 or the holder 21 and cleaned or replaced for maintenance.

Referring to fig. 4 and 7, in some possible embodiments, a mounting groove 2104 is laterally disposed on the support 21, the collecting box 25 is snap-fitted to the mounting groove 2104, a dust suction inlet 2105 communicating with the roller brush cavity 2102 is disposed in the mounting groove 2104, and a docking port 2501 docking with the dust suction inlet 2105 is disposed on the collecting box 25.

Therefore, through the clamping fit between the collecting box 25 and the mounting groove 2104, the collecting box 25 is detachably connected to the support 21, and the dirt is guided into the collecting box 25 through the dust suction inlet 2105 to be collected.

Furthermore, snap projections can also be provided on the collecting box 25, while the snap projections provided on the mounting groove 2104 also enable a snap connection of the collecting box 25.

In other possible embodiments, the collecting box 25 can be fixed to the support 21 by means of a threaded connection, such as a screw.

Referring to fig. 10 and 11, in some possible embodiments, an anti-flow plate 2502 is further disposed in the collection box 25, the anti-flow plate 2502 extends obliquely from a side of the docking port 2501 to a middle portion of the collection box 25, and the anti-flow plate 2502 extends upward from a bottom of the docking port 2501.

Therefore, the dirt enters the collecting box 25 along the anti-reverse flow plate 2502 under the action of negative pressure, and when the dirt passes through the tail end of the anti-reverse flow plate 2502, the dirt falls under the action of gravity, so that the dirt is collected in the collecting box 25, and due to the inclined arrangement of the anti-reverse flow plate 2502, the dirt in the collecting box 25 can be prevented from reversely flowing back out of the support 21 from the dust suction air inlet 2105 through the interface 2501, and the collection capacity of the collecting box 25 is further improved.

Referring to fig. 10 and 11, in some possible embodiments, the end of the reverse flow plate away from the docking port 2501 is provided with a downward-facing baffle 2503.

Thus, the provision of the baffle 2503 can further prevent the backflow of dirt out of the collection box 25.

In some possible embodiments, the baffles 2503 are circular arc shaped.

Thus, the arc-shaped baffle 2503 can smoothly guide the airflow, and reduce the generation of noise and vibration.

Of course, the baffle 2503 may also be configured as a straight plate in cases where vibration and noise requirements are not high.

Referring to fig. 10 and 11, in some possible embodiments, the collection box 25 is provided with an air outlet 2504, the air outlet 2504 and the interface 2501 are respectively located on two adjacent sides of the collection box 25, and the filter is disposed at the air outlet 2504.

Therefore, the arrangement mode can save space and is further beneficial to product miniaturization.

Referring to fig. 10, in some possible embodiments, a connection opening 2505 is disposed on a side surface of the collection box 25, a cover plate 2506 is inserted into the connection opening 2505, and the air outlet 2504 is disposed on the cover plate 2506.

Therefore, the cover plate 2506 can be detached to clean and maintain the interior of the collecting box 25, and the collection is convenient to clean.

In some possible embodiments, the filter is an air permeable screen (not shown) or a filter cloth (not shown) connected to the cover plate 2506 and covering the air outlet 2504.

Therefore, the structure is simplified, the whole weight of the cleaning device can be reduced, and the portability of the cleaning device is favorably realized.

Of course, other filters or filter structures known in the art may be suitable for use with the present solution.

The application process and the principle of the embodiment of the utility model are as follows:

when the multifunctional cleaning device is used, the steam brush head 1 and the roller brush device 2 can be detached, so that the roller brush device 2 and the steam brush head 1 can be independently used respectively, namely the roller brush device 2 can be used for independently removing dust or hair from clothes, the steam brush 1 can be used for independently ironing, and of course, after the steam brush head 1 and the roller brush device 2 are assembled, the steam brush head 1 can be used as a handle of the roller brush device 2 when steam is not introduced into the steam brush head 1.
