[0039] like Figure 1-Figure 7 As shown, the present invention provides an embodiment of a cleaning head structure for a cleaning device.

[0040] The cleaning head structure of the cleaning device includes a cleaning head body 1 and a roller 4 rotatably connected to the cleaning head body 1, and a wiper mechanism 6 is provided between the cleaning head body 1 and the roller 4. The wiper mechanism 6 is provided with a cleaning device that is used to clean the roller during the cleaning process. 4. Cleaning component for cleaning the garbage on the surface of the drum 4 .

[0041] Specifically, The wiper mechanism 6 is mainly used to prevent liquid from leaking when cleaning the drum 4. Before cleaning the drum 4, separate the larger particles from the drum 4 to avoid the larger particles from appearing during the cleaning process. The cleaning member includes a plurality of contacting rollers 4 arranged at intervals in the length direction. Cleaning block 65, a cleaning block 65 channel 67 is provided between two adjacent cleaning blocks 65 .

[0042] The wiper mechanism 6 includes a wiper body 61 and a first contact portion 64 and a second contact portion 63 that contact the surface of the roller 4. The first contact portion 64 is provided with a cleaning block 65, and the cleaning block 65 has two inclined surfaces on the side close to the surface of the roller 4. The intersection of the two inclined surfaces forms a point, that is, the cleaning block 65 is a triangular structure. Since each cleaning block 65 is arranged at intervals, The surface of the drum 4 can be pressed in the axial direction, so that the particles or elongated garbage on the surface of the drum 4 can be easily removed. Separated from roller 4 .

[0043] described The second contact portion 63 on the wiper mechanism 6 is provided with an extension portion 632 and a water blocking portion in a direction different from the extension portion. 631. The water retaining portion 631 can prevent the sewage from mixing with the clean water when cleaning the surface of the drum 4, thereby affecting the cleaning effect and further affecting the Impact on cleaning efficiency .

[0044] The tail of the second contact portion 63 is provided with a groove 66 arranged along the length direction. The groove 66 can help the surface of the cleaning drum 4 to better collect garbage, such as fine dust or solid particles.

[0045] The wiper mechanism 6 can be made of two materials of different hardnesses, with the wiper body 61 having a harder hardness than the first contact portion 64 and the second contact portion 63. The first contact portion 64 and the second contact portion 63 can be made of a soft material, such as an elastic material. The wiper body 61 is made of a hard material. This combination of hard and soft materials provides a certain degree of structural strength while also ensuring a certain amount of deformation space when interfering with the surface of the drum 4, providing good adaptability.

[0046] The wiper body 61 may be partially or completely covered by the first contact portion 64 and the second contact portion 63 .

[0047] described The second contact portion 63 is provided with protrusions 630 extending toward the roller 4 at both ends in the longitudinal direction. The protrusion 630 is triangular and can prevent the liquid at both ends of the drum 4 from being directed to the middle. .

[0048] As needed, The extension portion 632 is in contact with the surface of the roller 4 and is a sloped structure. The contact with the surface of the drum 4 forms a smooth transition with the surface of the cleaning part of the drum 4, which can better make the clean water flow smoothly during the cleaning process. It can clean a larger area of ​​the drum 4 and reduce the damage to the drum 4 and the inclined surface structure during the cleaning process. .

[0049] During use of the cleaning head structure for cleaning equipment, Because the cleaning component can remove fine particles before cleaning Clean the solid or slender garbage from the drum to avoid the garbage from being easily washed out during cleaning. The cleaning water tank is blocked, affecting the water and dust cleaning flow path. Affecting the cleaning efficiency, the structure is simple and compact .

[0050] The cleaning head structure also includes a shovel bar 5 for removing debris from the cleaning surface. This shovel bar 5 has a groove 52 on the side facing away from the roller 4. This groove 52 provides a certain degree of flexibility to adapt to different environments. The groove 52 runs along the length of the shovel bar 5 and is preferably parallel to the horizontal direction. A curved channel is provided between the shovel bar 5 and the roller 4. At the entrance of the curved channel, the shovel bar is provided with an inclined surface 51, which is at an angle of 15-30 degrees to the horizontal.

[0051] The trumpet-shaped structure B is formed between the inclined surface 51 of the shovel bar and the roller 4. Since the trumpet-shaped structure can be formed between the shovel bar 5 and the roller 4 through the inclined surface 51, it can better adapt to solid particles of different sizes, thereby improving the adaptability of use.

[0052] As needed, The cleaning head structure also includes a movable protective cover 3, which is connected to the main cleaning head. Hinge connection between body 1 The protective cover 3 is also provided with an energy absorbing block 31 in the height direction, and the energy absorbing block 31 is arranged perpendicular to the horizontal plane.
