In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] After the floor scrubber cleans the floor, various dirt will be adsorbed on the roller of the floor scrubber. In the self-cleaning process of the roller, the existing floor scrubber only uses water flow to clean the rotating roller. Due to the pressure of the water flow and the water storage capacity of the floor scrubber, the cleaning effect of the roller by water flow alone is poor, and the dirt on the roller cannot be completely cleaned. The dirt that is not cleaned up accumulates and deposits on the roller, which will cause secondary pollution to the floor when the floor scrubber cleans the floor, affecting the cleaning effect of the floor scrubber on the floor.

[0037] In order to solve the above problems, Figure 1As shown, an embodiment of the present invention provides a roller cleaning device 10 for cleaning the roller of a floor scrubber, the roller cleaning device 10 comprising a roller cleaning brush 110, a driving handle 120 and a driving device 130; wherein the roller cleaning brush 110 is in contact with the roller of the floor scrubber, and is used for cleaning the surface of the roller of the floor scrubber; the driving device 130 drives the roller cleaning brush 110 to move back and forth through the driving handle 120, and repeatedly rubs the surface of the roller of the floor scrubber.

[0038] Specifically, Figure 2A and Figure 2B As shown, the roller cleaning brush 110 includes a cleaning brush body 111 , and the cleaning brush body 111 has a first surface 112 and a second surface 113 that are disposed opposite to each other.

[0039] Among them, the first surface 112 of the cleaning brush body 111 is arranged opposite to the roller of the floor scrubber, and a cleaning part (not shown in the figure) is arranged on the first surface 112, and the cleaning part abuts against the roller of the floor scrubber. When the roller cleaning brush 110 cleans the roller, the cleaning part can rub the roller deeply and forcefully, thereby removing the dirt on the roller. Furthermore, the cleaning part is fixed to the first surface 112 in a detachable manner, for example, the cleaning part is detachably fixedly connected to the first surface 112 by a snap-on manner, or the cleaning part is detachably fixed to the first surface 112 by a fastener. In this way, different types of cleaning parts can be fixedly connected to the first surface 112 according to different requirements for cleaning the roller of the floor scrubber.

[0040] In some specific embodiments, the cleaning part may be a bristle structure, for example, bristles are arranged on the surface of a plate-like object. The plate-like object is connected to the first surface 112 in a detachable manner, and the cleaning part having a bristle structure is fixed on the first surface. When the cleaning part cleans the roller of the floor scrubber, the bristles of the cleaning part repeatedly rub the surface of the roller to achieve the purpose of cleaning the roller. In addition, the hardness, length, density of the bristles and the area of ​​the region where the bristles are arranged can also be set according to the needs of the cleaning effect.

[0041] In some specific embodiments, the cleaning part may also be a convex point structure, for example, convex points protruding from the surface of the plate-like object are provided on the surface of the plate-like object. The plate-like object is connected to the first surface 112 in a detachable manner, and the cleaning part having a convex point structure is fixed on the first surface. When the cleaning part cleans the roller of the floor scrubber, the convex points of the cleaning part are used to repeatedly squeeze and rub the surface of the roller to achieve the purpose of cleaning the roller. In addition, the hardness of the convex points, the height protruding from the surface of the plate-like object, the number of convex points, and the arrangement of the convex points on the surface of the plate-like object can also be set according to the needs of the cleaning effect, for example, uniform arrangement or random arrangement.

[0042] In some specific embodiments, the cleaning portion may also be a convex rib structure, for example, a convex rib protruding from the surface of the plate-like object is provided on the surface of the plate-like object. The plate-like object is connected to the first surface 112 in a detachable manner, and the cleaning portion having a convex rib structure is fixed on the first surface. When the cleaning portion cleans the roller of the floor scrubber, the convex rib of the cleaning portion repeatedly squeezes and rubs the surface of the roller to achieve the purpose of cleaning the roller. In addition, the shape of the convex rib, the height and length of the protruding surface of the plate-like object, and the arrangement of the convex rib on the surface of the plate-like object can also be set according to the needs of the cleaning effect. For example, the convex rib is serpentine or arc-shaped.

[0043] A variety of structures may also be provided on the surface of the plate-like object of the cleaning portion as required, for example, a bristle structure and a convex point structure may be provided on the plate-like object of the cleaning portion, or a convex point structure and a convex rib structure may be provided, or a bristle structure and a convex rib structure may be provided, or a bristle structure, a convex point structure and a convex rib structure may be provided. The embodiments of the present invention do not specifically limit this.

[0044] By setting the cleaning part to be fixed on the first surface 112 in a detachable manner, and combining the cleaning part to adopt a variety of structures according to cleaning needs, the user can set the corresponding cleaning part on the first surface 112 according to the type and amount of dirt adsorbed on the roller of the floor scrubber after the floor scrubber cleans the ground, so as to achieve targeted cleaning treatment for different types of dirt on the roller of the floor scrubber. In addition, the cleaning part is fixed on the first surface 112 in a detachable manner, which is convenient for replacing the cleaning part as needed. In addition, it is also convenient to remove the cleaning part from the first surface 112 when necessary, and clean the cleaning part separately without removing the roller cleaning brush 110. The entire part is removed. When the cleaning part is damaged or fails, it is also convenient to remove the cleaning part from the first surface 112 for repair or replacement. In addition, the cleaning part can also be fixed on the first surface 112 in a manner of being integrally formed with the first surface 112.

[0045] In a specific embodiment, the floor cleaned by the floor scrubber is very dry, and the dirt adsorbed on the floor scrubber roller is mainly fine dust particles. In this case, the cleaning part can adopt a bristle structure, and the dust particles on the floor scrubber roller are removed by rubbing the surface of the floor scrubber roller with the bristles.

[0046] In another specific embodiment, the floor cleaned by the floor scrubber is relatively wet, and the dirt adsorbed on the roller of the floor scrubber is mainly water. In this case, the cleaning part can adopt a convex rib structure, and the convex ribs can scrape the surface of the roller of the floor scrubber to remove the water adsorbed on the roller of the floor scrubber.

[0047] The first surface 112 can be set as a plane or as an arc surface parallel to the surface of the floor scrubber roller, thereby increasing the contact area between the cleaning portion set on the first surface 112 and the surface of the floor scrubber roller, thereby improving the cleaning effect of the floor scrubber roller.

[0048] like Figure 2A , Figure 2B and Figure 3 As shown, a guide portion 114 is provided on the second surface 113 of the cleaning brush body 111, and the guide portion 114 is provided along the axial direction of the roller of the floor scrubber. A guide groove 115 is provided on the guide portion 114, and the guide groove 115 is provided at an angle to the guide portion 114. One end of the driving handle 120 is connected to the driving device 130, and the other end of the driving handle 120 is slidably provided in the guide groove 115, so that the driving device 130 drives the roller cleaning brush 110 through the driving handle 120 to scrub the roller.

[0049] Specifically, the driving device 130 can be a motor and is fixedly arranged. One end of the driving handle 120 is connected to the output shaft of the motor so that the driving handle 120 can rotate around the output shaft of the motor under the drive of the motor. The other end of the driving handle 120 is arranged in the guide groove 115. When the driving handle 120 rotates around the output shaft of the motor under the drive of the motor, and the roller cleaning brush 110 is restricted by the guide part 114 so that the roller cleaning brush 110 can only move along the axial direction of the roller of the floor scrubber, the other end of the driving handle 120 arranged in the guide groove 115 pushes the roller cleaning brush 110 to move back and forth along the axial direction of the roller of the floor scrubber. The other end of the driving handle 120 arranged in the guide groove 115 can be connected to a slider arranged in the guide groove 115, and then the roller cleaning brush 110 is pushed to move back and forth along the axial direction of the roller of the floor scrubber through the slider.

[0050] Since the width of the guide groove 115 is greater than the width of the guide portion 114, the guide portion 114 can freely move repeatedly along the axial direction of the roller of the floor scrubber in the guide groove 115; at the same time, the guide portion 114 can also move in the guide groove 115 along the width direction of the guide groove 115 (i.e., the direction perpendicular to the extension direction of the guide groove 115). Specifically, if the guide groove 115 is arranged in the horizontal direction, then the width direction of the guide groove 115 is the vertical direction perpendicular to the horizontal direction. Therefore, the roller cleaning brush 110, driven by the driving device 130, can rub the roller of the floor scrubber along the axial direction of the roller of the floor scrubber (for example, the horizontal direction) and along the axial direction perpendicular to the roller of the floor scrubber (for example, the vertical direction), thereby achieving a better effect of cleaning the roller of the floor scrubber.

[0051] Furthermore, the shape and length of the guide groove 115 can be set according to the stroke of the roller cleaning brush 110 reciprocating along the axial direction of the roller of the scrubber. For example, the guide groove 115 can be set in a straight line or an arc shape (for example, a semicircular arc shape). When the guide groove 115 is a straight line, the angle between the guide groove 115 and the guide portion 114 can also be set as needed. For example, the guide groove 115 is set perpendicular to the guide portion 114, or is set at a 45° angle.

[0052] In order to improve the cleaning effect of the floor scrubber roller, Figure 4 As shown, the roller cleaning device 10 in this embodiment also includes a cleaning liquid delivery device 140, which is used to provide cleaning liquid for the roller cleaning brush 110. The cleaning liquid delivery device 140 includes a driving pump 141 and a cleaning liquid storage device 142. The driving pump 141 is connected to the cleaning liquid storage device 142 through a first pipeline 143, and is connected to the roller cleaning brush 110 through a second pipeline 144. The driving pump 141 sucks the cleaning liquid stored in the cleaning liquid storage device 142 through the first pipeline 143, and delivers the cleaning liquid to the roller cleaning brush 110 through the second pipeline 144. The roller cleaning brush 110 is provided with a diversion channel 116 that penetrates the cleaning brush body 111 and the guide portion 114, and one end of the second pipeline 114 is plugged into the diversion channel 116, which is used to deliver the cleaning liquid to the cleaning portion of the cleaning brush body 111.

[0053] like Figure 4 As shown, the driving pump 141 can be driven by the driving device 130, for example, the driving pump 141 and the driving device 130 share a motor, which drives the driving pump 141 to deliver the cleaning liquid in the cleaning liquid storage device 142 to the cleaning part of the roller cleaning brush 110 through the first pipeline 143, the second pipeline 144 and the diversion channel 116 while driving the roller cleaning brush 110 to move through the driving handle 120. In addition, the driving pump 141 and the driving device 130 can each include a motor, which is used to control the movement of the roller cleaning brush 110 and the delivery of the cleaning liquid.

[0054] Furthermore, the cleaning liquid delivery device 140 may include only the first pipeline 143 and the second pipeline 144, and the driving pump 141 and the cleaning liquid storage device 142 are arranged in the floor scrubber; or, the cleaning liquid delivery device 140 includes only the driving pump 141, the first pipeline 143 and the second pipeline 144, and the cleaning liquid storage device 142 is arranged in the floor scrubber.

[0055] Furthermore, the cleaning liquid delivery device 140 may be used only as a preferred embodiment. The roller cleaning device 10 may not include the cleaning liquid delivery device 140 .

[0056] When the roller cleaning brush 110 is cleaning the roller of the floor scrubber, the cleaning liquid can be delivered to the cleaning part (for example, bristles, bumps, and ribs) of the cleaning brush body 111 through the cleaning liquid delivery device 140, so that the roller cleaning brush 110 rubs the roller of the floor scrubber while applying the cleaning liquid to the surface of the roller of the floor scrubber, thereby obtaining a better cleaning effect. The embodiment of the present invention further provides a floor scrubber base 1, such as Figures 5 to 7 As shown, the floor scrubber base 1 includes the above roller cleaning device 10 and a base body 20. Among them, a concave cleaning groove 30 is provided in the middle of the base body 20 for accommodating the chassis 3 of the floor scrubber. A receiving chamber 40 for accommodating the roller cleaning device 10 is provided in the base body 20, and the receiving chamber 40 is located on both sides of the cleaning groove 30; a limiting groove 50 is provided on the side wall adjacent to the cleaning groove 30 of the receiving chamber 40, and a guide portion 114 is movably arranged in the limiting groove 50; and a cleaning brush body 111 is arranged in the cleaning groove 30. The limiting groove 50 is arranged along the axial direction of the roller of the floor scrubber, so that the cleaning brush body 111 can only move along the direction of the limiting groove 50, that is, along the axial direction of the tube wheel of the floor scrubber, through the guide portion 114 arranged in the limiting groove 50.

[0057] Furthermore, the base body 20 may be configured to be assembled from a bottom plate 21 and an upper shell 22 .

[0058] When the driving device 130 in the roller cleaning device 10 drives the driving handle 120 to rotate around the end of the driving handle 120 connected to the driving device 1, the end of the driving handle 120 arranged in the guide groove 150 pushes the roller cleaning brush 110 to move. Due to the restriction of the limiting groove 50 on the side wall of the accommodating cavity 40 and the cleaning groove 30 on the guide part 114, the cleaning brush body 111 can only reciprocate along the direction of the limiting groove 50, thereby realizing reciprocating rubbing of the roller of the floor scrubber along the axial direction of the roller of the floor scrubber, so as to achieve the purpose of cleaning the roller of the floor scrubber.

[0059] like Figure 2A and Figure 6 As shown, in a specific embodiment, the guide groove 115 is embedded in the guide portion 114, so a limiting hole 60 is provided at a position opposite to the guide groove 115 on the side wall of the accommodating chamber 40 adjacent to the cleaning tank 30, so as to provide space for the guide groove 115 to move along with the guide portion 114. The guide groove 115 may also be provided on the side of the guide portion 114 away from the cleaning brush 111 instead of being embedded in the guide portion 114, so that it is not necessary to provide a hole on the guide groove 115 to provide space for the movement of the guide groove 115.

[0060] In order to increase the stability of the washing machine base 1, an anti-skid pad is provided at the bottom of the base body 20 to increase the friction between the base body 20 and the ground.

[0061] The embodiment of the present invention further provides a floor scrubber, such as Figure 8 and Fig. 9 As shown, the floor scrubber includes a floor scrubber base 1, a floor scrubber body 2, a chassis 3 and at least one roller 4 as described above. Among them, at least one roller 4 is arranged at the end of the moving direction of the chassis 3. When the floor scrubber finishes cleaning the ground and needs to clean the roller 4 of the floor scrubber, the chassis 3 of the floor scrubber is placed in the cleaning tank 30 of the floor scrubber base 1, so that the roller 4 of the floor scrubber abuts against the cleaning portion arranged on the first surface 112 of the cleaning brush body 11. Then, the driving device 130 is started, so that the driving handle 120, driven by the driving device 130, pushes the cleaning brush body 111 to reciprocate along the axial direction of the roller 4 of the floor scrubber. In this process, the cleaning portion arranged on the first surface 112 of the cleaning brush body 111 repeatedly rubs the roller 4 of the floor scrubber in a transverse direction (i.e., along the length direction of the roller 4 of the floor scrubber), so that the dirt on the roller 4 of the floor scrubber is easier to clean. At the same time, the cleaning liquid delivery device 140 may be activated to deliver cleaning liquid to the cleaning portion on the first surface 112 , thereby further improving the cleaning effect on the roller 4 of the floor scrubber.

[0062] When two rollers 4 are arranged on the chassis 3 of the floor scrubber, a roller cleaning device 10 may be configured for each roller 4 in the accommodating cavity 40 in the floor scrubber base 1 .
