With the continuous development of technology and the improvement of the living standard of people, novel household appliances such as household cleaning equipment such as dust collectors, floor washers and the like are increasingly arranged in the lives of people.

At present, the cleaning device may include a main machine and a floor brush structure connected with the main machine, where the main machine is connected with the floor brush structure through a connecting rod and is rotatably arranged with respect to the floor brush structure. The floor brush structure is used for cleaning a surface to be cleaned (e.g., floor). Specifically, the cleaning apparatus may wet the cleaning member of the floor brush structure with the water tank and then wet-drag the cleaning member.

However, the floor brush structure is required to be provided with a special wiper strip to scrape the sewage of the cleaning member and recycle the sewage to the sewage tank, so that the cleaning workload of the floor brush structure after cleaning the floor is increased. In addition, since the sewage of the wet mop cleaning member is scraped by the wiper strip and then is absorbed into the sewage tank by negative pressure, the wet mop cleaning member occupies part of the suction force on the floor brush structure provided with the dry suction cleaning member and the wet mop cleaning member, which results in insufficient suction force of the dry suction cleaning member and poor dust collection effect of the cleaning device.

In view of the above problems, the utility model provides a floor brush structure and a cleaning device, wherein the floor brush structure controls the liquid amount of a clean water tank which is introduced into a water spraying part by arranging a liquid amount control unit, so that the liquid amount of the water spraying part sprayed to a floor mopping rolling brush is just used for cleaning the floor, after the floor mopping rolling brush is wet-mopped, the floor mopping rolling brush is not required to be subjected to water scraping operation, the cleaning workload after the floor mopping rolling brush mopped is reduced, sewage is not required to be recycled by negative pressure, and the suction force of a dry suction rolling brush is not influenced.

Thus, when the floor brush structure is driven to travel, the dry suction rolling brush 210 positioned at the front end of the traveling direction of the floor brush structure can be used for cleaning particles, dust or other dry garbage, and the floor mopping rolling brush 220 positioned at the rear end of the traveling direction of the floor brush structure can be used for mopping the floor, so that when the cleaning device travels, dust is sucked while the floor is mopped along the traveling direction, the labor intensity of a user is effectively reduced, and the cleaning efficiency of the cleaning device is improved.

The ground brush structure may be a straight path or a curved path during traveling, and it should not be understood that only a straight path exists, as long as the ground brush structure moves substantially along the front region in the traveling direction.

Alternatively, the manual control valve 342 may be disposed in the communication portion 341 in a translational manner, so that the relative position of the manual control valve 342 and the communication channel 3411 is changed by translating the manual control valve 342 relative to the communication channel 3411, so as to control the amount of liquid fed into the water spraying member 310 by the clean water tank 320.

In this way, by providing the communication portion 341 between the clean water tank 320 and the water spraying member 310 and providing the communication channel 3411 in the communication portion 341, both ends of the communication channel 3411 are respectively communicated with the clean water tank 320 and the water spraying member 310, so that the cleaning liquid in the clean water tank 320 flows through the communication channel 3411 and then enters the water spraying member 310, and the manual control valve 342 is provided, so that the amount of the cleaning liquid in the clean water tank 320 flowing into the water spraying member 310 can be adjusted by adjusting the relative positions of the manual control valve 342 and the communication channel 3411.

Illustratively, the blocking portion 3422 may rotate relative to the communication channel 3411 to change the flow cross-sectional area between the flow channel 3423 and the communication channel 3411, or the blocking portion 3422 may move relative to the communication channel 3411 in the extending direction of the blocking portion 3422 to change the flow cross-sectional area between the flow channel 3423 and the communication channel 3411.

In this way, by providing the flow channel 3423 on the blocking portion 3422, when the handle portion 3421 drives the blocking portion 3422 to move, the position of the flow channel 3423 is changed, and the flow rate of the communication channel 3411 is changed by changing the flow cross-sectional area between the flow channel 3423 and the communication channel 3411.

In a specific implementation, the blocking portion 3422 is rotatable about the first axis relative to the communicating portion 341 to change an angle between an extending direction of the liquid flow channel 3423 and an extending direction of the communicating channel 3411, where the extending direction of the first axis and the extending direction of the communicating channel 3411 have an angle therebetween.

For example, referring to fig. 13 and 15, the extending direction of the communication channel 3411 is a first direction along the horizontal direction, the extending direction of the liquid flow channel 3423 is a second direction along the horizontal direction, and the first axis is a vertical direction, so that when the blocking portion 3422 rotates around the first axis relative to the communication portion 341, the angle between the first direction and the second direction changes, when the first direction coincides with the second direction, the flow cross-sectional area between the liquid flow channel 3423 and the communication channel 3411 is the largest, the liquid inlet amount into the water spraying member 310 is the largest, and when the first direction rotates gradually away from the second direction, the flow cross-sectional area between the liquid flow channel 3423 and the communication channel 3411 is gradually reduced, and when the first direction is perpendicular to the second direction, the liquid flow channel 3423 is completely blocked, and no cleaning liquid is introduced into the water spraying member 310.

In this way, the plugging portion 3422 can rotate around the first axis by an angle relative to the communicating portion 341, so as to accurately control the amount of the liquid inlet flowing into the water spraying member 310.

It is understood that the blocking portion 3422 may have a cylindrical shape or a spherical shape, and when the blocking portion 3422 has a cylindrical shape, the first axis is aligned with the extending direction of the blocking portion 3422, and when the blocking portion 3422 has a spherical shape, the first axis is aligned with the rotational axis of the handle portion 3421.

Referring to fig. 16 and 17, in one possible implementation, the blocking portion 3422 is spherical, and a portion of the communication channel 3411 forms a limiting cavity that matches the shape of the blocking portion 3422, and the blocking portion 3422 is rotationally disposed in the limiting cavity.

In this way, by rotating the spherical blocking portion 3422 in the restriction chamber, the flow cross-sectional area between the flow channel 3423 and the communication channel 3411 is changed by changing the angle between the extending direction of the flow channel 3423 and the extending direction of the communication channel 3411.

To facilitate user manipulation, in some embodiments, the handle portion 3421 is a knob. Thereby facilitating the rotation of the blocking portion 3422 by the user.

Referring to fig. 10 and 13, in order to limit the rotation angle of the handle portion 3421, in some embodiments, a side of the handle portion 3421 facing the outer wall of the housing 100 has a first limiting portion 3424, and the first limiting portion 3424 is provided at one side of the handle portion 3421 in the rotation axis direction.

In this way, by providing the first limiting portion 3424 and the second limiting portion 110, the rotation angle of the handle portion 3421 in the circumferential direction of the handle portion 3421 is further controlled by the cooperation of the first limiting portion 3424 and the second limiting portion 110, so that a user can accurately know the current liquid inlet amount of the water spraying member 310.

In some embodiments, the first limiting portion 3424 is a limiting groove extending along the rotation direction of the handle portion 3421, and the second limiting portion 110 is a limiting protrusion located in the limiting groove, and the limiting protrusion can reciprocate along the length direction of the limiting groove relative to the limiting groove.

Alternatively, in other embodiments, the first limiting portion 3424 is a limiting protrusion, and the second limiting portion 110 is a limiting groove.

For example, after the user screws the handle portion 3421 forward to reach the limit, the limiting protrusion may abut against one end of the limiting groove, at this time, the flow cross-sectional area between the flow channel 3423 and the communication channel 3411 is maximum, after the user screws the handle portion 3421 backward to reach the limit, the limiting protrusion may abut against the other end of the limiting groove, at this time, the flow cross-sectional area between the flow channel 3423 and the communication channel 3411 is minimum, and when the limiting protrusion is located between two ends of the limiting groove, the screwing scale may be set, so that the user adjusts the amount of liquid inlet into the water spraying member 310 according to the cleaning requirement. Thus, the user can accurately control the amount of liquid fed into the water spraying member 310.

In some embodiments, the blocking portion 3422 is movable relative to the communication channel 3411 in a radial direction of the communication channel 3411 to change the size of the area occupied by the blocking portion 3422 in the cross section of the communication channel 3411.

That is, when the blocking portion 3422 moves in the radial direction of the communication channel 3411, the length of the blocking portion 3422 extending into the communication channel 3411 is changed, and thus the size of the area occupied by the cross section of the blocking portion 3422 in the communication channel 3411 can be changed, so that the size of the flow cross section area of the communication channel 3411 can be changed.
