[0013] The cross-section of the scraping strip is fan-shaped, and its inner end penetrates into the outer gap of the positioning cavity. The movable strip is slidably arranged in the movable cavity, and the communication cavity is connected to the corresponding movable cavity and through hole.

[0014] As a further description of the above technical solution:

[0015] The width of the outer gap is smaller than the width of the movable strip. The movable strip is an arc-shaped elastic structure, and its width is equal to the width of the movable cavity.

[0016] As a further description of the above technical solution:

When the surface cleanliness is high, the acting force between it and the scraping strip is small, and the movable strip always blocks the movable cavity. When the cleaning surface is relatively dirty, due to the frictional force and the tangential pushing of the surface protrusions, the scraping strip is locally laterally deformed, and the movable strip rotates and tilts in the movable cavity, so that the high-pressure cleaning liquid in the movable cavity rushes out of the movable cavity and the outer gap and spills onto the dirty part of the cleaning surface. After that, the floor brush can be repeatedly pushed to make the scraping strip mop the place. When the cleaning is completed, the tangential acting force on the local part of the scraping strip gradually decreases. Then, due to the centrifugal force applied during the rotation of the roller brush and the water pressure of the cleaning liquid in the movable cavity, the movable strip fits against the outer side of the movable cavity again, thereby realizing the re-blocking of the movable cavity and stopping watering the cleaning surface. Through the above structural design, the automatic control of the water spraying amount based on the dirt condition of the cleaning surface can be realized, and then the integrated suction and mopping use effect of the floor brush with high efficiency, energy saving and water saving can be achieved.

[0055] The connecting seat 5 includes a positioning seat 51 and a bearing seat 52. The positioning seat 51 is positioned on the roller brush cavity 11, and a first communication port 511 for docking the water supply pipe is provided thereon. The end parts of the bearing seat 52 are respectively docked with the cylinder body 21 and the positioning seat 51, and a second communication port 522 for docking the inner cavity 212 and the first communication port 511 is provided thereon.

Ribs 515 are provided on the inner surface or / and the outer surface of the joint pipe 514. The end of the water supply pipe is a double-layer pipe structure, and its inner pipe and outer pipe are respectively inserted into and sleeved on the joint pipe 514 and abutted against the ribs 515. This ensures the tight docking of the positioning seat 51 and the water supply pipe and ensures stable water supply.

[0059] The working principle of a combined suction and mopping floor brush according to this embodiment includes: when only the roller brush 2 is driven and the blower in the vacuum cleaner is running, the local floor brush can achieve vacuum cleaning of the cleaning surface; if surface mopping is required, the water pump is controlled to operate, so that the cleaning liquid in the water tank is pumped through the water supply pipe, the first communication port 511, the second communication port 522, the inner cavity, and the through hole 211 to the inside of the communication cavity 233 and the movable cavity 232. When the surface cleanliness is high, the force between it and the scraping strip 31 is small, and the movable strip 32 always blocks the movable cavity 232. When the cleaning surface is relatively dirty and messy, due to the frictional force and the tangential pushing of the surface protrusions, the scraping strip 31 undergoes local lateral deformation, and the movable strip 32 rotates and tilts in the movable cavity 232, so that the high-pressure cleaning liquid in the movable cavity 232 flushes out of the movable cavity 232 and the outer gap 231 and spills onto the dirty area of the cleaning surface. After that, the floor brush can be repeatedly pushed, so that the scraping strip 31 mopps the area. When the cleaning is completed, the tangential force on the local part of the scraping strip 31 gradually decreases, and due to the centrifugal force applied during the rotation of the roller brush 2 and the water pressure of the cleaning liquid in the movable cavity 232, the movable strip 32 re-fits on the outside of the movable cavity 232, thereby realizing the re-blocking of the movable cavity 232 and stopping watering the cleaning surface. Through the above structural design, automatic control of the water spraying amount based on the dirt condition of the cleaning surface can be achieved, and thus the integrated suction and mopping use effect of the floor brush with high efficiency, energy saving and water conservation can be achieved.
