It will be appreciated that the roller brush 100 may have an axis of rotation L and that in operation the roller brush 100 may contact a cleaning surface to be cleaned and may be rotated about the axis of rotation L to sweep the cleaning object. Illustratively, in some embodiments, the cleaning objects that the roller brush 100 may clean may include dust, mites, hair, solid particles, and the like.

Referring to fig. 1-3, the sleeve 110 has a peripheral wall 111 extending around the axis of rotation L. It is understood that the outer peripheral wall 111 is an annular wall surface surrounding the rotation axis L. The peripheral wall 111 in the present application may be circular around the rotation axis L, rectangular around the rotation axis L, or various other shapes around the rotation axis L. Further, the outer peripheral wall 111 may also extend in a direction parallel to the rotation axis L to form an axially extending structure thereof. It is understood that the sleeve 110 surrounds the rotation axis L and extends in the circumferential axial direction to extend in a sleeve shape, the center line of the sleeve 110 may coincide with the rotation axis L, and the outer peripheral wall 111 is a circumferential wall surface outside the sleeve 110.

Referring to fig. 1 to 3, the first boss 121 is connected to the outer peripheral wall 111. The first boss 121 extends in a direction away from the rotation axis L. It is understood that the first protrusion 121 protrudes from one end connected to the outer circumferential wall 111 toward the outside of the sleeve body 110. The first protrusion 121 may extend in any direction away from the rotation axis L and may have any cross-sectional shape, as appropriate for cleaning requirements. 1-3, in some embodiments, the first protrusion 121 may be rod-shaped, and the first protrusion 121 may be linearly protruded in a radial direction of the rotation axis L.

Referring to fig. 1-3, the first protrusion 121 is adapted to agitate the cleaning article. Specifically, to agitate the cleaning article, in some embodiments, a side of the first projection 121 remote from the axis of rotation L may be adapted to oscillate relative to the peripheral wall 111. It is understood that the first protruding portion 121 is connected to the outer peripheral wall 111 at one end and is swingable with respect to the outer peripheral wall 111 at the other end. In other words, the first boss 121 may include a connection end and a free end which are oppositely disposed, the connection end being connected to the peripheral wall 111, the free end being connected to a side of the connection end remote from the rotation axis L, it being understood that the connection end and the free end are two portions of the first boss 121 oppositely disposed in a radial direction of the rotation axis L, and the connection end is located on a side of the first boss 121 close to the rotation axis L in the radial direction of the rotation axis L, and the free end is located on a side of the first boss 121 remote from the rotation axis L in the radial direction of the rotation axis L. In various embodiments, the first protrusion 121 may actively move to agitate the cleaning object, or may be driven by the sleeve 110 to move to agitate the cleaning object.

Based on different connection modes, in different embodiments, the side of the first protruding portion 121 away from the rotation axis L may swing reciprocally in a certain direction, or may freely rotate around the connection end connected to the peripheral wall 111. The above-described swinging motion may be used, on the one hand, to collect the cleaning object to roll the cleaning object around the first protrusion 121; on the other hand, the hair can be used for loosening the winding of the cleaning object, specifically, a part of hair can be wound on the first protruding portion 121, and as the number of the wound hair increases, the part of hair can be difficult to clean and is easy to cut the first protruding portion 121, and the swinging action can be used for loosening the hair wound on the first protruding portion 121.

Referring to fig. 1 to 3, the second boss 130 is connected to the outer peripheral wall 111. The second boss 130 extends in a direction parallel to the rotation axis L and is projected in a direction away from the rotation axis L. It will be appreciated that the second protrusions 130 on the one hand extend in a direction away from the axis of rotation L as do the first protrusions 121, and that the second protrusions 130 on the other hand also extend in a direction parallel to the axis of rotation L, so that the second protrusions 130 may be rectangular, seen in a direction perpendicular to the axis of rotation L. Based on the arrangement of the embodiments described above, the second protrusion 130 is adapted to support a cleaning object. It will be appreciated that the swinging of the first protrusions 121 may be used to agitate the cleaning object, while at the same time, as part of the cleaning object (e.g. hair) is concentrated around the first protrusions 121, the second protrusions 130 may be used to support the cleaning object around the first protrusions 121, so that the cleaning object can be supported on the first protrusions with the rotation of the roller brush 100, and the cleaning object can be easily sucked away, and further winding of the cleaning object around other components during the rolling process (e.g. around other protrusions of the roller brush 100 or the assembly gap of the roller brush 100) can be avoided, so that the supporting action of the second protrusions 130 can reduce the movement amplitude of the cleaning object, so that most of the cleaning object is concentrated around the first protrusions 121. Further, in some embodiments, an adsorption component may be disposed around the roller brush 100 to suck the cleaning object adsorbed by the roller brush 100.

It should be noted that, in various embodiments, the second protrusion 130 may extend from one end of the sleeve 110 along the rotation axis L to the opposite end along the direction parallel to the rotation axis L; the second boss 130 may also extend a distance in a direction parallel to the rotation axis L that is less than the length of the sleeve 110 in that direction. Meanwhile, based on the usage requirement of the rolling brush 100, in different embodiments, the distance of the radial protrusion of the second protrusion 130 along the rotation axis L may be smaller than the distance of the radial protrusion of the first protrusion 121 along the rotation axis L, so that when the rolling brush 100 rolls, the first protrusion 121 contacts the cleaning object to be cleaned preferentially.

In some embodiments, the sleeve 110 may be directly connected to a driving assembly that drives the rolling brush 100, so that the sleeve 110 can rotate around the rotation axis L. In addition, referring to fig. 1-3, in some embodiments, the roll brush 100 may further include a shaft 140. The shaft body 140 may extend in a direction parallel to the rotation axis L corresponding to the extending direction of the rotation axis L. The shaft 140 may be configured to rotate about the rotation axis L to rotate the sleeve 110. To facilitate the assembly and disassembly of the sleeve 110, the sleeve 110 may be configured to be detachably sleeved on the shaft 140.

The central axis of the shaft body 140 may coincide with the rotation axis L. Based on this, in some embodiments, the sleeve 110 may have an opening extending in a direction parallel to the rotation axis L, so that the shaft 140 may extend into the opening, that is, the sleeve 110 may be sleeved on the shaft 140. The above arrangement may facilitate the rotation of the sleeve 110 about the rotation axis L, and thus, for convenience of description, the embodiment in which the sleeve 110 is sleeved on the shaft 140 will be described below, and in addition, in some embodiments, the rolling brush 100 may only drive the sleeve 110 to rotate about the rotation axis L, and the sleeve 110 does not rotate; in other embodiments, when the rolling brush 100 works, the sleeve 110 and the shaft 140 can be driven to rotate around the rotation axis L at the same time, that is, the sleeve 110 and the shaft 140 can be fixedly connected relatively, so that when the sleeve 110 or the shaft 140 is driven, the sleeve 110 or the shaft 140 can rotate around the rotation axis L at the same time.

Based on the above embodiments, in order to improve the integrity of the rolling brush 100, the rolling brush 100 is convenient to assemble and disassemble, and easy to clean, and in particular, the sleeve 110 is integrally connected with the first protruding portion 121 and the second protruding portion 130. In various embodiments, the manner of integral connection may include an integral molding process, welding, soldering, etc. Based on the requirement of integral molding, the sleeve 110, the first protruding portion 121 and the second protruding portion 130 may all be made of the same material. The above-mentioned setting can make the connection of three more firm, and just can accomplish the connection in the stage of making, is favorable to improving production efficiency, reduction in production cost. After the manufacturing, the sleeve 110, the first protruding portion 121 and the second protruding portion 130 are integrally connected, and the three may be directly detachably connected to a driving assembly for driving the rolling brush 100 or the shaft 140 (see the description of the above embodiment for details) capable of rolling the sleeve 110, so that the above integrated structural form can facilitate the disassembly, assembly and cleaning of the rolling brush 100.

According to a combination of the above embodiments, it can be seen that in some embodiments, the roller brush 100 has a sleeve 110 adapted to rotate about a rotation axis L, a first protrusion 121 adapted to swing to agitate the cleaning article, and a second protrusion 130 adapted to support the cleaning article, all of which are integrally connected. Compared with the split-type connected bristles in the prior art, the rolling brush 100 of the present application can loosen the hair wound around the first protrusion 121 by the swing of the first protrusion 121; on the other hand, the second protruding part 130 can be utilized to support the effect of the cleaning object so as to reduce the winding of the cleaning object and facilitate the collection of the cleaning object; in still another aspect, the integrally connected sleeve 110, the first protruding portion 121 and the second protruding portion 130 may facilitate the assembly, disassembly and cleaning of the rolling brush 100. Under the combined action of the first protruding part 121 and the second protruding part 130, the cleaning object is in a fluffy state on the rolling brush 100, is easy to suck away, and is not easy to wind.

It is understood that the first protrusion set 120a has an end near the second end surface 113, the second protrusion set 120b has an end near the first end surface 112, and the first end protrusions 121a and the second end protrusions 121b respectively located at the two ends may be adjacently spaced along a direction parallel to the rotation axis L. Based on the above arrangement of the first protrusion set 120a and the second protrusion set 120b, the above two arrangements may be combined, so that the extending direction of each first protrusion 121 of the first protrusion set 120a may be substantially symmetrical to the extending direction of each first protrusion 121 of the second protrusion set 120b, and thus the extending directions of the first protrusions of the two segments may be substantially V-shaped. The arrangement can make the arrangement direction of each first protrusion 121 adapt to the rolling direction of the rolling brush 100, and a great amount of cleaning objects can be gathered at the junction of the first protrusion set 120a and the second protrusion set 120b, i.e. the bottom of the V-shape.

In the fourth arrangement form of the embodiment, the first protrusions 121 may be plural, the plural first protrusions 121 may extend from one end of the sleeve body 110 along the rotation axis L to the other end of the sleeve body 110 along the rotation axis L, and the respective first protrusions 121 may be staggered in a direction perpendicular to the rotation axis L.

Further, referring to fig. 5, in some embodiments, the first protrusions 121 may be plural, and the plural first protrusions 121 aligned in a direction parallel to the rotation axis L may define the plural protrusion groups 120. That is, each of the first protrusions 121 may define a plurality of protrusion groups 120, each protrusion group 120 including a plurality of first protrusions 121 aligned in a direction parallel to the rotation axis L. It will be appreciated that the set of protrusions 120 is a combination of a plurality of first protrusions 121 arranged in a direction parallel to the rotation axis L, i.e. in some embodiments, a plurality of first protrusions 121 arranged in a direction parallel to the rotation axis L may be considered as a whole, and the roll brush 100 may comprise a plurality of sets of protrusions 120. Based on the above arrangement of the protrusion groups 120, in some embodiments, the protrusion groups 120 may be arranged at intervals in the circumferential direction of the rotation axis L. It will be appreciated that the plurality of protrusion sets 120 may be disposed around the rotation axis L, so that each protrusion set 120 may sequentially contact the cleaning surface during a period of one rotation of the roller brush 100, thereby improving cleaning efficiency.

Based on the arrangement of the protrusion set 120 in the above embodiments, in order to improve the effect of supporting the cleaning object by the second protrusion 130 and reduce the winding of the cleaning object, referring to fig. 1 to 5, in some embodiments, the second protrusion 130 may be multiple, and at least one protrusion set 120 may be disposed between every two adjacent second protrusions 130 along the circumferential direction of the rotation axis L. It will be appreciated that the above arrangement may be such that the second protrusions 130 are disposed on both sides of the protrusion group 120 in the circumferential direction of the rotation axis L, so that the second protrusions 130 located on both sides of the first protrusion 121 can be used to block displacement of the cleaning object around the first protrusion 121 on both sides of the rotation axis L in the circumferential direction, respectively, so that the cleaning object can be further gathered around the first protrusion 121. Referring to fig. 1-5, in some embodiments, one protrusion set 120 may be disposed between every two adjacent second protrusions 130, that is, there is only one row of first protrusions 121 disposed between two second protrusions 130 in a direction parallel to the rotation axis L, and the above arrangement may reduce the entanglement of the cleaning object between two adjacent protrusion sets 120 in combination with the supporting effect of the second protrusions 130. In some embodiments, the extending direction or the arrangement direction of the second protrusions 130 in the direction parallel to the rotation axis L may be the same as the arrangement direction of the plurality of first protrusions 121 in the direction parallel to the rotation axis L.

Based on the above-described arrangement of the first and second bosses 121 and 130, on the one hand, referring to fig. 6 or 7, in some embodiments, each of the first bosses 121 may include first and second bosses 121a and 121b sequentially arranged in the circumferential direction of the rotation axis L. It is understood that the first protruding piece 121a and the second protruding piece 121b are two first protruding portions 121 arranged opposite in the circumferential direction of the rotation axis L. One of the second bosses 130 may be a third boss 130a. The third protrusion 130a may be located between the first protrusion 121a and the second protrusion 121b in the circumferential direction of the rotation axis L. It will be appreciated that the third protrusion 130a may be a second protrusion 130 provided between the first protrusion 121a and the second protrusion 121b, corresponding to the arrangement of the above-described embodiments.

Based on the arrangement of the above-described embodiments, referring to fig. 6-8, in some embodiments, the third protrusion 130a may have a first wall surface 131a facing the first protrusion 121 a. In the radial direction of the rotation axis L, an orthographic projection of the first wall surface 131a on a plane perpendicular to the rotation axis L is a first projection extending from an end near the rotation axis in a direction in which the first protruding piece 121a points toward the second protruding piece 121 b. It will be appreciated that the third protrusion 130a may extend partially along the circumference of the rotation axis L such that the first wall surface 131a is at an acute angle with respect to the radial direction of the rotation axis L, i.e. the first wall surface 131a facing the first protrusion 121a is an inclined surface. Meanwhile, the above-mentioned change in the distance between the first wall surface 131a and the first protruding member 121a is defined such that the first wall surface 131a extends from the end close to the rotation axis L in a direction away from the first protruding member 121a and away from the rotation axis L at the same time, and therefore, the above-mentioned arrangement makes the first wall surface 131a slope, and the cleaning matters around the first protruding member 121a can move around the second protruding member 121b along the first wall surface 131a or be directly led out of the roller brush 100, so as to reduce the accumulation of the cleaning matters on the side of the third protruding member 130a facing the first protruding member 121a, which is inconvenient for cleaning. The first wall surface 131a may have different forms based on the above definition. In particular, referring to fig. 6-7, in some embodiments, the first projection may be straight, i.e., the first wall 131a may be a straight extending wall, which may facilitate the manufacture of the third protruding member 130a, facilitate the integral formation of the third protruding member 130a and the peripheral wall 111, and save costs; referring to fig. 8, in some embodiments, the first projection may be an arc, that is, the first wall 131a may be an arc, and the above arrangement can adapt the curvature of the first wall 131a to the rolling of the rolling brush 100, so as to improve the guiding effect on the cleaning object. Furthermore, in other embodiments, the first projection may have other shapes, i.e., the first wall 131a may have a special-shaped surface with other shapes, in order to adapt to the cleaning requirement. The definition of the first wall surface 131a in the above embodiment may also be understood that, in some embodiments, the rolling brush 100 rotates in the first circumferential direction when in operation, and the angle between the perpendicular line, which is directed from the side close to the rotation axis L to the side far from the rotation axis L and perpendicular to the first wall surface 131a, and the tangential direction of the first circumferential direction at the third protrusion 130a may be an obtuse angle.

Further, referring to fig. 6, in some embodiments, the third protrusion 130a may also have a second wall 132a facing the second protrusion 121b. The orthographic projection of the second wall surface 132a on a plane perpendicular to the rotation axis L is a second projection. The second projection extends from an end near the rotation axis L in a direction in which the second protruding piece 121b points toward the first protruding piece 121 a. It will be appreciated that the second projection is similar to the definition of the first projection, except that the second wall 132a defining the second projection faces the second protrusion 121b. The form of the second wall surface 132a can be referred to as the first wall surface 131a described above. Based on the above arrangement, the first projection and the second projection may both be straight. In the radial direction of the rotation axis L, one end of the first wall surface 131a and one end of the second wall surface 132a, which are close to the rotation axis L, may be both connected to the outer peripheral wall 111, and one end of the first wall surface 131a, which is far from the rotation axis L, may be connected to one end of the second wall surface 132a, which is far from the rotation axis L. It should be understood that the above limitation on the first wall surface 131a and the second wall surface 132a means that the first wall surface 131a and the second wall surface 132a are two opposite slope surfaces, and the cross section of the third protrusion 130a along the direction perpendicular to the rotation axis L is triangular, so that the first wall surface 131a and the second wall surface 132a can both guide the cleaning object and adapt to different rotation directions of the rolling brush 100.

On the other hand, the first and second protrusions 121 and 130 are provided in plural numbers. Referring to fig. 9-10, in some embodiments, one of the sets of projections 120 may be the first set 120c. The first bosses 121 of the first group 120c have gaps 122 therebetween. It will be appreciated that each first protrusion 121 in the first set 120c may be spaced apart in a direction parallel to the rotation axis L, such that there may be a gap 122 between two adjacent first protrusions 121. Each of the second bosses 130 may include a third boss 130a and a fourth boss 130b sequentially arranged in a circumferential direction of the rotation axis L. It is understood that the third protrusion 130a and the fourth protrusion 130b are two second protrusions 130 oppositely arranged along the circumferential direction of the rotation axis L. The first protrusion 121 may be located between the third protrusion 130a and the fourth protrusion 130b in the circumferential direction of the rotation axis L.

Based on the arrangement of the above embodiment, referring to fig. 9 to 10, the roll brush 100 may further include a guide protrusion 150, and the guide protrusion 150 may be connected to the outer circumferential wall 111. Similar to the first protrusion 121 or the second protrusion 130 described above, in some embodiments, the guide protrusion 150 may also extend in the circumferential direction of the rotation axis L or in a direction parallel to the rotation axis L and protrude in a direction away from the rotation axis L. The guide protrusion 150 may include a first guide portion 151 and a second guide portion 152 that are oppositely disposed. In some embodiments, the first guide 151 and the second guide 152 may be oppositely disposed in a direction parallel to the rotation axis L. The first guide portion 151 and the second guide portion 152 may each extend from a side of the first protruding portion 121 near the third protruding member 130a to a side of the first protruding portion 121 near the fourth protruding member 130b, and penetrate through the gap 122, so that the outer peripheral wall 111, the first guide portion 151, and the second guide portion 152 together define the guide groove 160. It is understood that the first guide portion 151 and the second guide portion 152 may be located between the third protruding member 130a and the fourth protruding member 130b, and may extend along the circumferential direction of the rotation axis L, and both may penetrate through the gap 122, so that the side walls of the two opposite guide portions and the outer peripheral wall 111 of the bottom may jointly define the guide groove 160. The above arrangement defining the guiding groove 160 may enable a part of the cleaning object to be located in the guiding groove 160, and along the extending direction of the guiding groove 160, the other end of the cleaning object is guided by one end of the rolling brush 100 along the circumferential direction of the rotation axis L, so as to be beneficial to avoiding aggregation of the cleaning object.
