Detailed Description

The present invention will be further explained with reference to the drawings and examples.

The cleaning head is a component part of the floor washing machine, and the dust collection flow channel of the cleaning head is improved.

Referring to fig. 1 to 4, the cleaning head includes: a cleaning head main body 1, a roller brush 4, a driving device (not shown), and a clean water discharge device (not shown). The inside dust absorption runner that has of cleaning head main part 1, the dust absorption runner is including going into dirt mouth 3 and bellows 2, and bellows 2 is used for the intercommunication to go into dirt mouth 3 and the sewage case 8 of floor cleaning machine fuselage (see fig. 5), and round brush 4 supports in the round brush mounting groove 6-1 of cleaning head main part 1 front end through the axle, and the face of cleaning of round brush 4 is relative with going into dirt mouth 3, can take the water stain to dust absorption mouth 3 on ground when round brush 4 rotates, drive arrangement is used for the drive round brush 4 rotates, clear water eduction gear installs cleaning head main part 1, clear water eduction gear include water jet and pump usually, the pump be used for from clear water case 12 (see fig. 5) to the water jet extraction clear water, the water jet can set up to the orientation round brush 4 or towards ground, in order to moisten round brush 4 or moist ground. The construction of the above-described cleaning head is known in the art.

Referring to fig. 3, the improvement of this embodiment is that a water collecting tank 6 is disposed at the dust inlet 3 of the dust collection flow channel, and can collect the sewage flowing back from the dust collection flow channel after the floor cleaning machine stops working. In the present embodiment, the water collection tub 6 is configured by providing the upward protruding portion 5 on the lower edge of the dust inlet 3 facing the wiping surface of the roller brush 4, that is, the water collection tub 6 of the present embodiment includes: the bottom of the dust inlet 3 of the dust collection flow channel; and an upward protrusion 5 provided at a lower edge of the dust inlet 3 opposite to the wiping surface of the roll brush 4.

Referring to fig. 4, along a direction from both ends of the roller brush to the middle of the roller brush, the bottom of the water collecting tank 6 is gradually inclined downward (from the outside to the inside in fig. 4), and the side of the water collecting tank 6 away from the roller brush is gradually inclined in a direction away from the roller brush, thereby forming a flow guide structure. This water conservancy diversion structure makes the water in the ponding groove 6 can flow along dotted line arrow direction in figure 4, and this makes, and at the ground in-process of washing, the sewage that is brought into in the ponding groove 6 by the round brush can assemble to the export of entering dirt mouth 3 automatically under the action of gravity to improve the suction efficiency of subaerial water stain, reduced the energy consumption.

Referring to fig. 4, the length of the water collecting tank 6 is matched with the length of the rolling brush mounting groove 6-1, namely the length of the rolling brush, so that the sewage raised by the rolling brush can be completely collected into the water collecting tank 6 in the floor washing process.

Wherein, the inner wall surface of the water collecting tank 6 is designed to be a smooth surface, so that the sewage can flow in the water collecting tank 6.

Referring to fig. 3, the bottom of the dust inlet 3 is a smooth arc structure gradually rising along the sewage flow direction, so that the end of the dust inlet 3 is closer to the ground.

Referring to fig. 2, the bottom of the dust inlet 3, the water collecting groove 6 and the bottom case of the cleaning head main body 1 are integrally formed, so that the manufacture is more convenient.

In figure 5 there is shown a floor scrubbing machine in which the cleaning head described above is used.

Referring to fig. 5, the present scrubber includes: a body assembly 10, a handle assembly 13 and a cleaning head 7. The body assembly 10 is provided with a clean water tank 12, a sewage tank 8, a suction motor 11 and a battery 9, the handle assembly 13 is arranged at the tail end of the body assembly 10, the front end of the body assembly 10 is connected with a cleaning head, the cleaning head 7 adopts the cleaning head of the embodiment, the corrugated pipe 2 (shown in figure 2) of a dust suction flow passage of the cleaning head 7 is communicated with the sewage tank 8 and the suction motor 11, and a pump of the cleaning head 7 is communicated with the clean water tank 12.

The working principle is as follows: when cleaning, the clear water spraying device is controlled to extract clear water from the clear water tank 12 and spray the clear water to the rolling brush 4, the rolling brush 4 is wetted, the driving device drives the rolling brush 4 to rotate, the ground is cleaned, water lifted by the rolling brush 4 during working can enter the dust inlet 3 in advance, the water collecting tank 6 and the flow guide structure inside the water collecting tank play a role in relaying and drainage, and meanwhile, under the action of the suction force of the suction motor 11, sewage can enter the corrugated pipe 2 of the sewage flow channel along the flow guide structure in the water collecting tank 6 and then enter the sewage tank 8. When the cleaning process is stopped, water sucked onto the inclined surface of the dust inlet 3 flows into the water accumulating tank 6 along the force, so that secondary pollution caused by the water flowing to the ground is prevented.

Therefore, the water accumulation groove 6 can prevent the water remained in the sewage flow channel from flowing back to the ground to form secondary pollution after the cleaning is stopped, and the user experience can be improved. And the diversion structure in the water accumulating tank 6 can make the water in the water accumulating tank 6 converge towards the outlet of the dust inlet 3 by utilizing the action of gravity, thereby improving the suction efficiency of the sewage and reducing the energy consumption.

The present invention has been described in detail with reference to the specific embodiments, and the detailed description is only for assisting the skilled person in understanding the content of the present invention, and can not be understood as the limitation of the protection scope of the present invention. Various decorations, equivalent changes and the like which are performed on the scheme by the technical personnel in the field under the conception of the invention are all included in the protection scope of the invention.
