The other end of the water spraying pipe 31 is prevented from being set as the open end 33, so that the cleaning water in the water spraying pipe 31 can directly flow out from the other end, and the amount of the cleaning water sprayed out from the water outlet hole 311 is small, which may cause that the local water content of the cleaning elements 22 is too large, and the other parts are wetted to a too small extent, which may affect the cleaning effect of the cleaning elements 22; alternatively, the cleaning water flowing out of the other end of the water spray pipe 31 may flow to other parts in the floor brush housing 1, which may damage other parts in the housing 1.

Alternatively, the inner diameter of the spout 31 may be uniform from the open end 33 to the closed end 34; alternatively, the inner diameter of the spout 31 may gradually decrease from the open end 33 to the closed end 34. As shown in FIG. 6, for the internal configuration of the spout 31, the internal diameter of the spout 31 can be consistent from the open end 33 to the closed end 34, i.e., the interior of the spout 31 is a cylindrical wall, which facilitates the forming of the interior of the spout 31, and the smooth interior wall does not impede the flow of water; alternatively, the inner diameter of the nozzle 31 may gradually decrease from the open end 33 to the closed end 34, and the open end 33 is the end where the nozzle 32 is disposed, so that the water flow rate and pressure at the open end 33 are high, and the water flow rate and pressure decrease as the cleaning water flows toward the closed end 34, thereby conforming to the flow of the cleaning water inside the nozzle 31 by disposing the nozzle 31 in a manner that the inner diameter gradually decreases from the open end 33 to the closed end 34.

It will be appreciated that the inner diameter of the spout 31 decreases from the open end 33 to the closed end 34, and that the inner wall of the spout 31 is smoothly transitioned at all times so as not to obstruct the flow of cleaning water, i.e., the inner wall of the spout 31 may be a smooth conical wall. Wherein the conical tube wall may be in a form in which the tube wall thickness from the open end 33 to the closed end 34 increases uniformly in the circumferential direction; the wall thickness of the tube on the side away from the drum 21 may gradually increase from the open end 33 to the closed end 34, and the wall thickness of the tube on the side facing the drum 21 where the water outlet hole 311 is disposed may be consistent from the open end 33 to the closed end 34, which is not limited in this embodiment.

In a possible embodiment, the water spray assembly 3 may include one water spray pipe 31, or the water spray assembly 3 may include a plurality of water spray pipes 31, the plurality of water spray pipes 31 are spaced apart in the circumferential direction of the drum 21, in which case, both ends of the water spray pipes 31 may extend to both ends of the drum 21. No matter the cleaning assembly 2 has only one roller 21, the cleaning member 22 is wrapped on the surface of the roller 21 and is in line contact with the ground, or the cleaning assembly 2 has a plurality of rollers 21 horizontally spaced, the cleaning member 22 is wrapped on the outer surfaces of the plurality of rollers 21 and is in plane contact with the ground, the water spray pipe 31 of the embodiment is correspondingly arranged above the roller 21, and two ends of the water spray pipe 31 can extend to two ends of the roller 21, so that the water spray pipe 31 can cover the roller 21 in the length direction of the roller 21, and therefore, the cleaning water sprayed outwards from the plurality of water outlet holes 311 arranged in the length direction of the water spray pipe 31 can uniformly wet all parts of the cleaning member 22 in the direction, and then the roller 21 drives the cleaning member 22 to rotate, and further the cleaning water sprayed from the water outlet holes 311 can uniformly wet the whole cleaning member 22.

It should be noted that, in order to make the water outlet hole 311 convenient for spraying cleaning water to the cleaning member 22, the water spraying pipe 31 may be disposed right above the roller 21 of the cleaning assembly 2 of the single roller 21, or the water spraying pipe 31 may be disposed above the plane of the cleaning member 22 corresponding to the cleaning assembly 2 of the multiple rollers 21, so that the water outlet hole 311 of the water spraying pipe 31 may be vertically directed to the cleaning member 22, and the cleaning water can be effectively sprayed to the surface of the cleaning member 22 by means of the spraying pressure and gravity; alternatively, the water spray pipe 31 may be provided obliquely above the cleaning unit 2 so that the water outlet direction of the water outlet holes 311 is obliquely downward toward the cleaning member 22.

Specifically, as shown in fig. 1, the axis of the water spray pipe 31 may be parallel to the axis of the drum 21. By arranging the water spray pipe 31 along the axial direction of the drum 21 so that the axis of the water spray pipe 31 is parallel to the axis of the drum 21, the water spray pipe 31 has a short length while covering all portions of the drum 21 in the longitudinal direction, the arrangement of the water spray pipe 31 in the housing 1 is facilitated, and the manufacturing cost of the water spray pipe 31 can be saved. Thus, the plurality of water outlet holes 311 arranged on the water spray pipe 31 at intervals are parallel to the axis of the roller 21, the cleaning water sprayed from the plurality of water outlet holes 311 can wet all parts of the cleaning piece 22 in the axial direction of the roller 21, and all parts of the whole cleaning piece 22 can be wetted along with the continuous spraying of the water outlet holes 311 and the rotation of the cleaning piece 22 along with the rotation of the roller 21.

In another possible embodiment, the water spray assembly 3 may comprise a plurality of water spray pipes 31, and different water spray pipes 31 correspond to different sections in the axial direction of the drum 21. In the case that the water spraying assembly 3 includes a plurality of water spraying pipes 31, the plurality of water spraying pipes 31 may be arranged in the axial direction of the drum 21, so that different water spraying pipes 31 correspond to different positions in the length direction of the drum 21, and the plurality of water spraying pipes 31 may cover more positions in the length direction of the drum 21, or even all positions in the length direction of the drum 21, so that all the water outlet holes 311 provided in the plurality of water spraying pipes 31 may well wet all the positions of the cleaning member 22 in the direction.

Specifically, the plurality of spray pipes 31 may be located on the same straight line. Through making many spray pipes 31 be located same straight line, this straight line can be followed the one end of cylinder 21 and extended to the other end of cylinder 21 to the apopore 311 of many spray pipes 31 can be followed the one end of cylinder 21 to the comparatively even interval distribution of the other end, so that the cleaning water that makes apopore 311 spray can comparatively even moist each part of cleaning member 22 on this straight line orientation, no longer describe here.

The straight line of the water spray pipes 31 can be inclined to the axis of the roller 21, for which purpose, the water spray pipes 31 can be located above the plane of the cleaning elements 22 in the cleaning assembly 2 in the form of a multi-roller 21; alternatively, the axes of the plurality of water jets 31 may be parallel to the axis of the roller 21, for which the plurality of water jets 31 may be located directly above the roller 21 of the cleaning assembly 2 in the form of a single roller 21, or the plurality of water jets 31 may be located above the planar portion of the cleaning members 22 in the cleaning assembly 2 in the form of a plurality of rollers 21, or the plurality of water jets 31 may be located diagonally above the roller 21 of the cleaning assembly 2 in the form of a single roller 21 or a plurality of rollers 21.

In one embodiment, as shown in fig. 2 or fig. 3, the water spraying assembly 3 may include two water spraying pipes 31, the two water spraying pipes 31 are respectively located at two sides of the drum 21, and one end of each water spraying pipe 31 is located at two ends of the drum 21 and the other end extends to the middle of the drum 21.

As shown in fig. 1 and 2, a dust suction opening 12 is generally formed at a bottom end of the housing 1 of the floor brush, and an air duct 13 communicating with the dust suction opening 12 is generally formed at a middle portion of the housing 1 above the drum 21, so that air containing dust from the outside enters the air duct 13 through the dust suction opening 12. In this embodiment, in order to save the space of the housing 1 of the floor brush and make the floor brush have a smaller external dimension, two water spraying pipes 31 may be respectively disposed at two sides of the air duct 13 above the roller 21, one end of each water spraying pipe 31 at two sides is located at the end of the roller 21, and the other end extends toward the middle of the roller 21, that is, the other end is close to the air duct 13 in the middle.

Thus, the two water spray pipes 31 and the air duct 13 can be arranged in the same horizontal space, and the water spray pipes 31 can not additionally occupy the space of the floor brush in the height direction, so that the floor brush has smaller height; meanwhile, except for the position of the air duct 13, the two water spraying pipes 31 can cover other positions in the length direction of the roller 21, so that the water outlet holes 311 in the water spraying pipes 31 can still uniformly spray cleaning water to more positions of the cleaning piece 22 in the length direction of the roller 21, the whole cleaning piece 22 can be uniformly wetted, and the floor brush has a good cleaning effect.

In addition, as mentioned above, for the cleaning assembly 2 in the form of a single roller 21 or a plurality of rollers 21, the two water spray pipes 31 may be inclined to the axis of the roller 21 to cover the roller 21 in the longitudinal direction, or the two water spray pipes 31 may be on the same straight line, the axes of the two water spray pipes 31 on the same straight line may have an angle with the axis of the roller 21, or the axes of the two water spray pipes 31 may be parallel to the axis of the roller 21.

Specifically, the open ends 33 of the two spray pipes 31 may be located at two ends of the drum 21, and the closed ends 34 of the two spray pipes 31 may be located near each other and at the middle of the drum 21. As shown in fig. 2, in the case that one water spraying pipe 31 is respectively disposed on both sides above the drum 21, the open ends 33 of the two water spraying pipes 31 can be disposed at the end of the drum 21, so that the water spraying nozzles 32 are disposed at both ends of the drum 21, the water spraying nozzles 32 do not occupy the space above the drum 21, and the closed ends 34 of the water spraying pipes 31 can be disposed as close to the air duct 13 in the middle as possible, so that the water spraying pipes 31 cover more positions in the length direction of the drum 21, and further the water outlet holes 311 can cover more positions of the cleaning members 22 in the direction, and the cleaning water sprayed from the water outlet holes 311 can wet more positions of the cleaning members 22, so that the wetting area of the cleaning members 22 is larger and the wetting degree is more uniform.

As to the specific arrangement of the outlet 311 on the sprinkler pipe 31, as shown in fig. 4 to 6, in one possible embodiment, the outlet 311 may be formed along a radial direction of the sprinkler pipe 31, and a plurality of the outlets 311 may be arranged at regular intervals along a length direction of the sprinkler pipe 31.

As shown in fig. 6, in this embodiment, the water outlet hole 311 can be opened along the radial direction of the water spraying pipe 31, that is, the water outlet direction of the water outlet hole 311 is along the radial direction of the water spraying pipe 31, which is convenient for processing the water outlet hole 311 on the one hand, and on the other hand, the water outlet direction of the water outlet hole 311 can be determined more easily, for example, when the water spraying pipe 31 is disposed directly above the roller 21 of the single-roller 21 cleaning assembly 2 or directly above the plane of the cleaning members 22 of the multi-roller 21 cleaning assembly 2, the water outlet hole 311 can be vertically oriented to the plane of the roller 21 or the cleaning members 22, and the water outlet hole 311 can vertically spray the cleaning water to the plane of the roller 21 or the cleaning. In addition, in the case where the spray pipe 31 is disposed obliquely above the drum 21, the water outlet holes 311 may be directed toward the upper surface of the drum 21, so that the water outlet holes 311 spray the cleaning water toward the cleaning members 22.

In this embodiment, the plurality of water outlet holes 311 are uniformly spaced in the longitudinal direction of the water spray pipe 31, so that the cleaning water sprayed from the water outlet holes 311 can uniformly wet each part of the cleaning member 22, and the cleaning member 22 has a better cleaning effect.

Specifically, the water outlet 311 may be a circular hole or a slit. No matter the water outlet hole 311 is set as a circular hole or the water outlet hole 311 is set as a slit, since the circular hole and the slit have smaller sizes, the water outlet hole 311 can spray cleaning water outwards at higher pressure, and the sprayed cleaning water can wet all parts of the cleaning element 22 more uniformly.

In one possible embodiment, the cross-sectional area of the plurality of water outlet holes 311 may be uniform; alternatively, the cross-sectional area of the outlet opening 311 may decrease from the open end 33 to the closed end 34. By keeping the cross-sectional areas of the water outlet holes 311 consistent, the spraying pressure and the spraying range of the cleaning water sprayed from all the water outlet holes 311 are similar, so that the wetting degree of each part of the cleaning element 22 is uniform; by providing a smaller cross-sectional area of the outlet opening 311 from the open end 33 to the closed end 34 of the spout 31, i.e., a smaller outlet opening 311 from the open end 33 to the closed end 34 of the spout 31, the pressure of the spray from the open end 33 to the outlet opening 311 at the closed end 34 is correspondingly increased, and the spray range may be expanded, which may ensure a more consistent wetting of the closed end 34 and the open end 33 for a smaller flow rate and velocity of the cleaning water at the closed end 34.

In order to further improve the smoothness of the outlet hole 311 for spraying the cleaning water outwards, as shown in fig. 7 and 8, in one possible embodiment, the spray pipe 31 may further be provided with an outlet hole 35, and the cross-sectional area of the outlet hole 35 may be smaller than the cross-sectional area of the outlet hole 311. Like this through set up venthole 35 on spray pipe 31, and the cross-sectional area of venthole 35 is less, can discharge the air in the rivers in the spray pipe 31 through venthole 35, can guarantee that the more smooth and easy apopore 311 of the clean water in the spray pipe 31 outwards sprays.

Specifically, as shown in fig. 7 and 8, the air outlets 35 may be arranged adjacent to the water outlet holes 311 at intervals, or one air outlet 35 is disposed between every two water outlet holes 311. By arranging the air outlet holes 35 and the water outlet holes 311 adjacently at intervals, or arranging one air outlet hole 35 between every two water outlet holes 311, the water spray pipe 31 can uniformly spray water to the cleaning piece 22 through the water outlet holes 311, and meanwhile, air in the water spray pipe 31 can be discharged through the air outlet holes 35. In addition, the air outlet holes 35 and the water outlet holes 311 may be distributed on the water spraying pipe 31 in other arrangement manners, as long as the water outlet holes 311 can uniformly spray the cleaning water to each part of the cleaning member 22 in the length direction of the drum 21, which is not limited in this embodiment.
