Specifically, since the plurality of liquid outlets 111 are arranged at the same height, the cleaning member 20 can be wetted by the liquid sprayed from the plurality of liquid outlets 111 along the axial direction of the cleaning member 20, and the wetting effect can be more uniform. For example, in some embodiments, the liquid outlets 111 are all long openings, each long opening can realize waterfall type water spraying, and the height of the long openings is the same, so that the wetting effect of the cleaning element 20 is more uniform in the axial direction of the cleaning element 20, and the achieved wetting effect is better.

Specifically, the extension direction of the fitting groove 1191 may be parallel to the extension direction of the body portion 118, the fitting groove 1191 may be recessed toward a direction away from the spraying portion 119, and the opening direction of the fitting groove 1191 may be opposite to the spraying portion 119. Further, a fitting (not shown) may be disposed at an end of the spraying portion 119 opposite to the body portion 118, and the fitting may be disposed opposite to the fitting groove 1191, so that the spraying portion 119 may be mounted on the body portion 118 by fitting the fitting and the fitting groove 1191, thereby improving stability after connection between the spraying portion 119 and the body portion 118.

With continued reference to FIG. 8, in some embodiments of the present invention, the end surface of the body portion 118 adjacent to the cleaning members 20 is configured as a first arc-shaped surface 1192, the end surface of the spraying portion 119 adjacent to the cleaning members 20 is configured as a second arc-shaped surface 1193, and the first arc-shaped surface 1192 and the second arc-shaped surface 1193 are coplanar to form an arc-shaped surface in the above-described embodiments. Specifically, first arcwall 1192 and second arcwall 1193 can constitute arcwall 112 jointly, and arcwall 112 can improve the structural strength of liquid spray mechanism 10, and arcwall 112 is difficult to persist the dirt, and arcwall 112 is suitable for and corresponds the arrangement with cleaning member 20, for example adjacent or relative arrangement, and like this, when liquid rotates along with cleaning member 20, receive the effect of centrifugal force, and liquid can erode arcwall 112, and arcwall 112 does not have clean dead angle, is difficult for remaining sewage and dirt, does benefit to and improves clean effect.

In some embodiments of the present invention, the tangent line of the lower end of the arc surface 112 forms an included angle β with the horizontal plane, which satisfies the following relation: beta is more than 0 degree and less than or equal to 90 degrees. That is to say, the included angle between the tangent line of the lower end of the arc-shaped surface 112 and the horizontal plane is an acute angle or a right angle, so that when water at the lower end of the arc-shaped surface 112 flows out, the pressure is the same as the direction of gravity, thereby facilitating quick drainage, improving the drainage effect at the lower end of the liquid spraying mechanism 10, avoiding sewage from staying at the lower end of the arc-shaped surface 112, preventing objects such as garbage from remaining on the arc-shaped surface 112, and facilitating the surface cleaning of the arc-shaped surface 112.

In some embodiments of the present invention, arc-shaped surface 112 is disposed corresponding to cleaning element 20, and arc-shaped surface 112 is recessed toward spray body 11, so that arc-shaped surface 112 can surround the outer circumferential surface of cleaning element 20, which is beneficial for adapting arc-shaped surface 112 to cleaning element 20, so that cleaning element 20 can clean arc-shaped surface 112 during operation or rotation, and the spatial arrangement effect can be improved.

Further, the first arcuate surface 1192 and the second arcuate surface 1193 may be located on the same spherical surface to collectively form the arcuate surface 112. The arc-shaped surface 112 may be an arc, which may improve the matching degree between the liquid spraying mechanism 10 and the cleaning element 20, and when the cleaning element 20 runs or rotates, the outer surface of the cleaning element 20 may keep the same distance with the arc-shaped surface 112, which may improve the cleaning effect, and may also avoid interference between the cleaning element 20 and the arc-shaped surface 112 during the rotation process, thereby ensuring smooth rotation of the cleaning element 20.

With continued reference to fig. 8, in some embodiments of the invention, first arcuate surface 1192 and second arcuate surface 1193 each conform to the shape of cleaning members 20. That is to say, the radian of first arcwall face 1192 and second arcwall face 1193 can set up according to the shape of cleaning piece 20 for the radian of first arcwall face 1192 and second arcwall face 1193 matches with the radian of cleaning piece 20 surface, can further improve the clean effect of cleaning piece 20, improves the self-cleaning function of scrubbing brush 100.

With continued reference to fig. 6 and 8, in some embodiments of the present invention, the liquid outlet 111 is disposed near the upper end of the spraying portion 119. Specifically, the liquid outlet 111 may be located at a position above the liquid spraying mechanism 10, the setting height of the liquid outlet 111 is higher than the central axis of the cleaning member 20, but the setting height of the liquid outlet 111 does not exceed the top end of the cleaning member 20, the liquid outlet 111 may spray water upwards, and does not face the cleaning member 20, so as to form waterfall type water spraying, and the water is sprinkled onto the cleaning member 20, so as to avoid blocking the liquid outlet 111, meanwhile, the sprayed water may fully contact with the cleaning member 20 in the process of flowing downwards, so that the cleaning member 20 is more uniform in wetting. It should be noted that, in the embodiment of the present invention, the shape of the liquid outlet 111 is not particularly limited, for example, the liquid outlet 111 may be a strip-shaped opening, a cylindrical opening, and the like.

In the working process, because at least one liquid outlet 111 is arranged close to the top end of the liquid spraying mechanism 10, the distance between the liquid outlet 111 and the central axis of the cleaning part 20 in the height direction of the floor brush 100 is large, the number of the liquid outlets 111 can be reasonably set, for example, the liquid outlets 111 are distributed densely, and the liquid sprayed out from the liquid outlets 111 can be collected into waterfall type water flow, so that the cleaning part 20 can be wetted more uniformly, and the cleaning effect of the cleaning device 200 is improved.

Alternatively, the liquid outlet 111 may be disposed near the bottom end or the lower end of the arc surface 112, and the liquid is directly sprayed to the cleaning member 20 after flowing out from the liquid outlet 111.

Specifically, the number of the liquid outlets 111 may be plural, so that the flow rate of the sprayed liquid can be effectively increased. The liquid outlet 111 can be used to spray liquid to the cleaning members 20 to wet the cleaning members 20, thereby improving the cleaning effect of the floor brush 100. In addition, in the direction of height of scrubbing brush 100 (as shown in fig. 1 the Z direction), at least one liquid outlet 111 can be located between the central axis of cleaning piece 20 and the top of cleaning piece 20, and further, the height that sets up of at least one liquid outlet 111 can be the same with the height that sets up on the top of cleaning piece 20, the height that sets up of liquid outlet 111 can set up according to actual demand is nimble promptly, and then this liquid outlet 111 can not be just to cleaning piece 20, can effectively avoid cleaning piece 20 directly get rid of business turn over liquid mouth 111 at filth etc., avoid liquid outlet 111 to take place to block up, avoid influencing the cleaning efficiency of scrubbing brush 100. For example, in the embodiment where the liquid spraying mechanism 10 is provided with a plurality of liquid outlets 111, some of the liquid outlets 111 are opposite to the cleaning member 20, and the rest of the liquid outlets 111 can be located between the central axis of the cleaning member 20 and the top end of the cleaning member 20, even if the liquid outlets 111 opposite to the cleaning member 20 are blocked, the rest of the liquid outlets 111 can wet the cleaning member 20, and the cleaning effect of the floor brush 100 is improved.

It should be noted that, in the height direction of the floor brush 100, if the liquid outlet 111 is located below the central axis of the cleaning member 20, it is not favorable for the liquid sprayed from the liquid outlet 111 to wet the cleaning member 20; if the liquid outlet 111 is located above the top end of the cleaning member 20, the thickness of the floor brush 100 is increased, the manufacturing cost is increased, and there may occur a case where the liquid cannot be sprayed to the cleaning member 20. And in the direction of height of the floor brush 100, the liquid outlet 111 is located between the central line of the cleaning part 20 and the top end of the cleaning part 20, so that waterfall type water spraying and wetting of the cleaning part 20 can be formed, and meanwhile, the volume of the floor brush 100 can be reduced and the space resource occupation of the floor brush 100 can be reduced by reasonably setting the distance between the liquid outlet 111 and the axis of the cleaning part 20 in the direction of height of the floor brush 100.
