Referring to fig. 1, a roller brush 10 according to some embodiments of the present application includes a roller 11 and a first protruding member 13. The roller body 11 includes opposite first and second ends 111, 113 in the length direction X. The first protruding member 13 is disposed at the second end 113 of the roller body 11, and extends from the second end 113 of the roller body 11 in a direction away from the first end 111 of the roller body 11, the first protruding member 13 is spaced from a long axis MM1 of the roller body 11, and the long axis MM1 extends from the first end 111 of the roller body 11 to the second end 113 of the roller body 11. The first protruding member 13 is spaced from the long axis MM1 of the roller body 11, specifically, the extending direction of the first protruding member 13 is spaced from the extending direction of the long axis MM1 of the roller body 11.

In some embodiments, the length direction X of the roll body may be the direction from the first end 111 of the roll body 11 to the second end 113 of the roll body 11; or the direction of the second end 113 of the roller 11 to the first end 111 of the roller 11. The roller body 11 is rotatable relative to the surface to be cleaned. In the case of a rotation of the roller body 11 relative to the surface to be cleaned, the first projection 13 rotates together with the roller body 11 relative to the surface to be cleaned. However, to ensure that the first protruding member 13 is capable of agitating the contaminants at the second end 113 of the roller body 11, the first protruding member 13 needs to be spaced apart from the central axis of the roller body 11, whereby, in this application, the long axis MM1 may be the central axis of the roller body 11, in other words, the long axis MM1 may coincide with the central axis of the roller body 11.

In certain embodiments, the first protrusion 13 is one or more. Wherein the one or more first protrusions 13 are each spaced from the long axis MM1 of the roller body 11, whereby the one or more first protrusions 13 are each capable of agitating dirt at the second end 113 of the roller body 11 in case the roller body 11 rotates with respect to the surface to be cleaned, thereby securing the cleaning effect of the roller brush 10. In some embodiments, the first projection 13 can be attached to the second end 113 of the roller body 11 by a non-removable connection such as welding or adhesive. In other embodiments, the first projecting member 13 may be removably attached to the second end 113 of the roller body 11 by a snap fit or threaded connection. In still other embodiments, the first projection 13 can be integrally formed with the roller body 11 and positioned at the second end 113 of the roller body 11.

With continued reference to fig. 1, in some embodiments, the roller brush 10 may further include a cleaning member 15, where the cleaning member 15 is disposed on the peripheral wall 115 of the roller 11, and the cleaning member 15 is configured to clean dirt from the surface to be cleaned and direct the dirt to the second end 113 of the roller 11.

Specifically, in some embodiments, in the case that the roller 11 rotates relative to the surface to be cleaned, the cleaning member 15 can rotate together with the roller 11 relative to the surface to be cleaned, so as to clean the dirt on the surface to be cleaned. Wherein the surface to be cleaned can be a surface to be cleaned in a building; alternatively, the surface to be cleaned may be a surface of another object to be cleaned, such as a wall surface or a bed surface.

In some embodiments, the cleaning member 15 may include a flexible glue brush 151. The flexible rubber brush 151 not only can meet the cleaning requirement of the rolling brush 10 on the surface to be cleaned, but also can prevent the rubber brush 151 or the surface to be cleaned from being damaged due to the rigid contact between the rubber brush 151 and the surface to be cleaned, thereby ensuring the working stability of the rolling brush 10. In other embodiments, the cleaning member 15 can include a plurality of bristles 153, each bristle 153 including opposite first and second ends 1531, 1533, the first ends 1531 of the bristles 153 being connected with the peripheral wall 115 of the roller body 11. Wherein the second ends 1533 of the bristles 153 are closer to the second end 113 of the roller body 11 than the first ends 1531 of the bristles 153, i.e., the second ends 1533 of the bristles 153 are inclined toward the second end 113 of the roller body 11 with respect to the long axis MM1 of the roller body 11, thereby facilitating the guiding of the dirt to the second end 113 of the roller body 11 when the roller brush 10 cleans the dirt, and also reducing the residence time of the dirt on the roller brush 10, and improving the cleaning efficiency of the roller brush 10. The material of the bristles 153 includes, but is not limited to, nylon or PPT. In still other embodiments, the cleaning member 15 may include a brush 151 and bristles 153, the brush 151 being spaced from the bristles 153.

In some embodiments, in the case that the cleaning member 15 includes the rubber brush 151, the cleaning member 15 may be non-detachably mounted on the peripheral wall 115 of the roller body 11 by means of adhesion, welding or interference fit, so as to prevent the cleaning member 15 from falling off when the roller body 11 rotates relative to the surface to be cleaned, and improve the working stability of the rolling brush 10; or the cleaning member 15 can be detachably mounted on the peripheral wall 115 of the roller body 11 by clamping or screwing, etc., so that the cleaning member 15 can be conveniently detached for replacement when damaged. In the case where the cleaning member 15 includes bristles 153, the cleaning member 15 may be mounted to the peripheral wall 115 of the roller body 11 in a tufted manner.

In the roller brush 10 of the present embodiment, the second end 113 of the roller body 11 is provided with the first protruding member 13 extending from the second end 113 of the roller body 11 in a direction away from the first end 111 of the roller body 11, and the first protruding member 13 is spaced from the long axis MM1 of the roller body 11, so that the first protruding member 13 can stir the dirt at the second end 113 of the roller body 11, prevent the dirt from continuously accumulating, and ensure the collecting effect of the dirt absorbing device (not shown in the figure) on the dirt, thereby improving the cleaning capability of the roller brush 10.

The roll brush 10 is further explained below with reference to the drawings.

Referring to fig. 1, in some embodiments, the first projection 13 is tapered in a direction in which the first end 111 of the roller 11 is directed toward the second end 113 of the roller 11.

Specifically, if the size of the first protruding member 13 is unchanged or the size of the first protruding member 13 is gradually increased along the direction from the first end 111 of the roller body 11 to the second end 113 of the roller body 11, if there is a winding such as hair or string in the dirt, the winding is easily wound on the outer peripheral wall of the first protruding member 13 and is difficult to fall off by itself, so that the winding is more difficult to be collected by the dirt suction device (not shown), and the cleaning effect of the cleaning apparatus 1000 (shown in fig. 8) is further affected. In this application, along the direction from the first end 111 of the roller 11 to the second end 113 of the roller 11, the size of the first protruding member 13 gradually decreases, that is, the outer peripheral wall of the first protruding member 13 is inclined with respect to the central axis of the first protruding member 13, so that when the first protruding member 13 agitates the dirt, the hair or the string and other windings in the dirt are difficult to be wound on the inclined outer peripheral wall of the first protruding member 13, or when the windings are wound on the inclined outer peripheral wall of the first protruding member 13, the windings can also be automatically dropped under the guiding action of the inclined outer peripheral wall of the first protruding member 13, thereby ensuring that the dirt can be collected by the dirt absorbing device and improving the cleaning effect of the cleaning device 1000. It should be noted that, in some embodiments, the first protruding member 13 is at least one of a truncated cone-shaped protrusion, a conical protrusion, and a stepped protrusion. For example, in the case where the first projection 13 is a conical projection, the bottom of the conical projection is located at the second end 113 of the roller body 11 and the top (tip) of the conical projection is opposite the inside (shown in fig. 5) of the second end 23 of the housing 10.

In some embodiments, the first protruding member 13 is disposed on the end surface 1131 of the second end 113 of the roller body 11, i.e., the first protruding member 13 extends from the end surface 1131 of the second end 113 of the roller body 11 in a direction away from the first end 111 of the roller body 11. Referring to fig. 1 and 2, in some embodiments, where the first protrusions 13 are plural, the first protrusions 13 are uniformly distributed around the long axis MM 1. Therefore, when the roller 11 rotates relative to the surface to be cleaned, the first protruding member 13 agitates the dirt more orderly, so that the phenomenon that the hair or the twine such as the twine in the dirt is more firmly wound on the second end 113 of the roller 11 when the first protruding member 13 agitates the dirt is avoided, and the cleaning effect of the rolling brush 10 is ensured. Specifically, the plurality of first protruding members 13 are uniformly distributed around the long axis MM1, that is, the distances between the plurality of first protruding members 13 and the long axis MM1 are the same, and the distances between two adjacent first protruding members 13 are the same.

Referring to fig. 1 and 3, in other embodiments, where there are a plurality of first protrusions 13, the plurality of first protrusions 13 are unevenly distributed about the long axis MM 1. Thus, in the case where the roller body 11 rotates relative to the surface to be cleaned, the agitating area of the first projection 13 for the dirt is larger, so that the cleaning efficiency of the cleaning apparatus 1000 (shown in fig. 8) for the dirt can be improved. Specifically, the plurality of first protrusions 13 are unevenly distributed about the long axis MM1, i.e., at least two of the plurality of first protrusions 13 are different in distance from the long axis MM 1. For example, in the case where the first protruding pieces 13 include two, the distances between the two first protruding pieces 13 and the long axis MM1 are different. It will be appreciated that in some embodiments, where there are three or more first protrusions 13, the non-uniform distribution of the plurality of first protrusions 13 about the long axis MM1 may be: the distances between at least two first protruding pieces 13 of the plurality of first protruding pieces 13 and the long axis MM1 are different; and/or, the distance between two adjacent first projections 13 is different in the circumferential direction of the roller body 11. For example, in the case where the first protruding pieces 13 include three, the distances between at least two first protruding pieces 13 of the three first protruding pieces 13 and the long axis MM1 are different. For another example, in the case where the first projecting members 13 include three, the distances between adjacent two first projecting members 13 are different in the circumferential direction of the roller body 11. For another example, in the case where the first projections 13 include three, the distances between at least two first projections 13 of the three first projections 13 and the long axis MM1 are different, and the distances between adjacent two first projections 13 are also different in the circumferential direction of the roller body 11.

Referring to fig. 1 and 4, in still other embodiments, where the first protrusions 13 are plural, the first protrusions 13 are uniformly or unevenly distributed around the long axis MM1 at the second end 113 of the roller 11 and are located on one side of the short axis AA1 of the roller 11, and the short axis AA1 is perpendicular to the long axis MM1. Specifically, referring to FIG. 4, in some embodiments, the minor axis AA1 can divide the end surface 1131 of the second end 113 of the roller body 11 into a first side and a second side. The first plurality of projections 13 are each located on either the first side or the second side.

In some embodiments, a portion of the cleaning members 15 can extend beyond the second end 113 of the roller body 11 to form the first projecting member 13. Specifically, in some embodiments, where the cleaning member 15 includes a flexible glue brush 151, a portion of the cleaning member 15 is mounted to the peripheral wall 115 of the roller body 11 and another portion extends to the second end 113 of the roller body 11 and is located outside of the roller body 11. In this case, the portion of the cleaning member 15 extending beyond the second end 113 of the roller body 11 can form the first protrusion 13 to agitate the dirt located at the second end 113 of the roller body 11, preventing accumulation of the dirt. It should be noted that, in the case where a part of the structure of the cleaning member 15 protrudes out of the second end 113 of the roller body 11 to form the first protruding member 13, the first protruding member 13 is located outside the end surface 1131 of the second end 113 of the roller body 11.

In some embodiments, where a portion of the structure of the cleaning member 15 extends beyond the second end 113 of the roller body 11 to form the first projecting member 13, the size of the portion of the structure of the cleaning member 15 extending beyond the second end 113 of the roller body 11 may be gradually reduced in a direction in which the first end 111 of the roller body 11 is directed toward the second end 113 of the roller body 11, i.e., the cross-sectional size of the portion of the structure of the cleaning member 15 mounted on the peripheral wall 115 of the roller body 11 may be larger than the cross-sectional size of the portion of the structure of the cleaning member 15 extending beyond the second end 113 of the roller body 11. For example, the cross-sectional shape of the portion of the cleaning member 15 that is mounted on the peripheral wall 115 of the roll body 11 and the cross-sectional shape of the portion of the cleaning member 15 that extends beyond the second end 113 of the roll body 11 may be rectangular, and the cross-sectional size of the portion of the cleaning member 15 that is mounted on the peripheral wall 115 of the roll body 11 may be larger than the cross-sectional size of the portion of the cleaning member 15 that extends beyond the second end 113 of the roll body 11. It should be noted that, in some embodiments, the portion of the cleaning member 15 extending beyond the second end 113 of the roller body 11 may also be at least one of a truncated cone-shaped protrusion, a conical protrusion, and a stepped protrusion.

It will be appreciated that in other embodiments, the portion of the cleaning member 15 that is mounted to the peripheral wall 115 of the roller body 11 may be the same size as the portion of the cleaning member 15 that extends beyond the second end 113 of the roller body 11.

In some embodiments, the first end 111 of the roller 11 is configured to be rotatably coupled to one end of the housing 20 of the roller brush device, and the second end 113 of the roller 11 is configured to be suspended. When the rolling brush 10 rotates, the garbage on the surface to be cleaned is driven to the accommodating cavity 21, and some hairs in the garbage can be wound on the rolling brush 10. In this way, the second end 113 of the roller body 11 is suspended, and hair can move from the first end 111 of the roller body 11 to the second end 113 of the roller body 11, and is separated from the roller brush 10 at the second end 113 of the roller body 11, so that the effect of preventing the hair from winding the roller brush 10 is achieved.

Referring to fig. 1, in some embodiments, the roller brush 10 includes a blocking member 101, where the blocking member 101 is disposed at a first end 111 of the roller body 11 for blocking hair from being wound between an end of the first end 111 of the roller body 11 and the housing 20 of the roller brush device. The blocking member 101 may serve to block hair from being entangled between the end of the first end 111 of the roller body 11 and the housing 20, and even prevent hair from entering a position where the roller brush 10 is rotatably coupled with the housing 20, thereby preventing the roller brush 10 from being limited in rotation function.

In some embodiments, the roller brush 10 includes a first cleaning member that is mounted to the outer peripheral wall 115 of the roller body 11 and a second cleaning member that is a glue brush 151. The second cleaning member is mounted on the outer circumferential wall 115 of the roller body 11 and is spaced apart from the first cleaning member, the second cleaning member includes a plurality of bristles 153, the second cleaning member includes opposite first ends (i.e., first ends 1531 of the bristles) and second ends (i.e., second ends 1533 of the bristles), the first ends of the second cleaning member are connected with the outer circumferential wall 115 of the roller body 11, the second ends of the second cleaning member are spaced apart from the outer circumferential wall 115 of the roller body 11, and the second ends of the second cleaning member are closer to the first cleaning member than the first ends of the second cleaning member. Therefore, when the rolling brush 10 rotates to clean dirt, the winding matters such as hair in the dirt are difficult to sink into the gap between the first cleaning piece and the second cleaning piece, so that the winding matters are prevented from winding on the roller body 11, the cleaning performance of the rolling brush 10 is improved, and the normal operation of the cleaning equipment is ensured.

In some embodiments, the second cleaning element is inclined from the first end toward the second end 113 of the roller 11, such that the second cleaning element guides the hair or garbage on the roller 10 to move from the first end 111 toward the second end 113 of the roller 11 when the roller 10 rotates, and the hair can be separated from the roller at the second end 113 of the roller 11.

In some embodiments, the second end 113 of the roller 11 is suspended, the roller brush 10 includes a blocking member 101, the blocking member 101 is disposed at the first end 111 of the roller 11, and the second cleaning member is gradually inclined from the first end to the second end in a direction approaching the second end 113 of the roller 11.
