[0022] In the present application, the orientation words such as "upper", "lower", "top", "bottom" are generally directed to the directions shown in the drawings, or are directed to the vertical, perpendicular or gravity directions of the components themselves, unless otherwise specified. Similarly, for the convenience of understanding and description, "inner" and "outer" refer to the inner and outer relative to the contour of the components themselves, but the above orientation words are not used to limit the present application.

[0023] Embodiment 1 The present embodiment provides a rolling brush, such as Figures 1 to 4 As shown in the first embodiment, the rolling brush 100 comprises a main body 110 and a plurality of first bristles 120, which are circumferentially spaced on the main body 110. Further, the rolling brush 100 also comprises a plurality of insertion strips 130, each of which is radially connected to one first bristle 120 to form an axially extending cleaning strip 132, in other words, each cleaning strip 132 comprises two parts connected in the radial direction, namely the insertion strip 130 and the first bristle 120. The circumferential surface 111 of the main body 110 is provided with a plurality of lateral insertion grooves 112 corresponding to the insertion strips 130. Each insertion strip 130 is laterally inserted into one lateral insertion groove 112 and tightly fits with the lateral insertion groove 112, thereby fixing the cleaning strip 132 on the main body 110. Each first bristle 120 protrudes out of the lateral insertion groove 112 and protrudes from the circumferential surface 111, which can rotate with the main body 110 to sweep the ground and play a role in cleaning the ground.

[0024] In the present embodiment, the main body 110 is a rigid rolling shaft structure. Each cleaning strip 132 is a flexible strip structure, which can be made of, but not limited to, soft rubber, and can also be made of other flexible materials. Moreover, the cleaning strip 132 is an integral structure. The lateral insertion groove 112 is T-shaped in radial cross-section, but is not limited to this shape. The insertion strip 130 of the cleaning strip 132 is correspondingly T-shaped, which can be laterally inserted and clamped in the lateral insertion groove 112. The first bristle 120 is blade-shaped, but is not limited to this shape. It should be noted that in other embodiments, part of the cleaning strips 132 can be set as bristle strips according to actual needs, that is, the material of the first bristle 120 is bristle, and part of the cleaning strips 132 are rubber strips, and the bristle strips and rubber strips are alternately arranged.

[0025] In the embodiment, each first brush strip 120 comprises a first cleaning section 121 and a second cleaning section 122. The first cleaning section 121 comprises a first cleaning part 123 and a first swing part 124, the outer end of the first cleaning part 123 is arranged corresponding to one end of the main body 110, and the inner end of the first cleaning part 123 is connected with the first swing part 124 and forms an angle α1 at the connection. The second cleaning section 122 comprises a second cleaning part 125 and a second swing part 126, the outer end of the second cleaning part 125 is arranged corresponding to the other end of the main body 110, and the inner end of the second cleaning part 125 is connected with the second swing part 126 and forms an angle α2 at the connection. Wherein, the first swing part 124 and the second swing part 126 are spaced apart in the circumferential direction and at least partially staggered in the axial direction, so as to swing the winding on at least one of the first swing part 124 and the second swing part 126. The winding can be hair or other filament, linear object.

[0026] By segmenting the first brush strip 120 into the first cleaning section 121 and the second cleaning section 122, and forming an angle on the first cleaning section 121 and the second cleaning section 122, the winding on the roller brush 100 will first accumulate at the angle, at this time, the winding has not been tightly wound on the first brush strip 120 and can continue to migrate to the first swing part 124 and / or the second swing part 126. Since the first swing part 124 and the second swing part 126 are arranged in the circumferential direction and at least partially staggered in the axial direction, when the roller brush 100 rotates, the first swing part 124 and the second swing part 126 will swing in the circumferential direction, gradually untangle the winding on the first swing part 124 and / or the second swing part 126, and even shake off the winding, achieving the effect of preventing winding, without the need for additional cleaning of the winding, improving the user experience, and avoiding the situation that the winding affects the cleaning ability of the roller brush 100. Moreover, the angle on the first cleaning section 121 and the second cleaning section 122 can increase the structural strength of the connection, avoid the winding accumulated at the angle from tightening the connection and continuing to migrate, and also solve the problem that the winding tightens the first brush strip 120 and affects the cleaning efficiency. In addition, since the first brush strip 120 is disconnected, when the roller brush 100 rotates, it avoids rigid contact with the ground, reduces the noise generated when contacting, and solves the problem of large noise of pure rubber brush.

[0027] In principle, when the rolling brush 100 rotates, the first brush bar 120 stretches under the action of inertia, and a similar effect of increasing diameter is generated. When the first swinging part 124 and the second swinging part 126 contact the ground or are interfered by the ground, they swing / bend and deform along the rotation direction, and move close to each other and shrink. After leaving the ground, the first swinging part 124 and the second swinging part 126 restore the elastic deformation, and move away from each other and expand, and then the circumferential swinging phenomenon appears. This phenomenon can gradually remove or even shake off the winding objects on the first swinging part 124 and / or the second swinging part 126, so as to prevent the winding objects from winding on the rolling brush 100, and avoid the situation that the winding objects are tightened on the brush bar and affect the cleaning efficiency.

[0028] It should be noted that the skilled person in the art can set the size of the corner α1 of the first cleaning section 121 and the corner α2 of the second cleaning section 122 according to actual needs, but the corner α1 will not be set to an angle at which the winding object cannot migrate to the first swinging part 124, and the corner α2 will not be set to an angle at which the winding object cannot migrate to the second swinging part 126. As for the migration direction of the winding object, when the first cleaning part 123 and the second cleaning part 125 extend towards each other, the winding object migrates from both ends of the main body 110 inward; when the first cleaning part 123 and the second cleaning part 125 extend in the same direction, the winding object generally migrates from one end of the main body 110 to the other end.

[0029] Further, the size of the corner α1 of the first cleaning section 121 is 155°-175°, and the size of the corner α2 of the second cleaning section 122 is 155°-175°. Within this angle range, the bending amplitude of the first cleaning section 121 and the first cleaning section 121 is small, which is beneficial to the migration of the winding object from both ends of the main body 110 inward to the first swinging part 124 and the second swinging part 126 or the migration of the winding object from one end of the main body 110 to the other end through the first swinging part 124 and the second swinging part 126.

[0030] In the embodiment, the corner α1 of the first cleaning section 121 and the corner α2 of the second cleaning section 122 are both 165°, the circumferential swinging of the first swinging part 124 and the second swinging part 126 is better, and the winding object is more likely to migrate on the first cleaning section 121 and the second cleaning section 122. It can be understood that in other embodiments, the corner α1 of the first cleaning section 121 can also be 155°, 160°, 170° or 175°, and the corner α2 of the second cleaning section 122 can also be 155°, 160°, 170° or 175°.

[0031] In the embodiment, each lateral slot 112 is segmented into a first slot segment 113 and a second slot segment 114 corresponding to the first cleaning segment 121 and the second cleaning segment 122 respectively. Each insertion strip 130 is segmented into a first insertion segment 134 and a second insertion segment 136 corresponding to the first cleaning segment 121 and the second cleaning segment 122 respectively, the first insertion segment 134 radially connects the first cleaning segment 121, and the second insertion segment 136 radially connects the second cleaning segment 122. The first insertion segment 134 is inserted into the first slot segment 113 from one end of the body 110, and the first cleaning segment 121 extends out of the first slot segment 113. The shape and extension direction of the first cleaning segment 121 are limited by the shape and extension direction of the first slot segment 113, i.e., the first slot segment 113 defines the shape and extension direction of the first cleaning segment 121. The second insertion segment 136 is inserted into the second slot segment 114 from the other end of the body 110, and the second cleaning segment 122 extends out of the second slot segment 114. The shape and extension direction of the second cleaning segment 122 are limited by the shape and extension direction of the second slot segment 114, i.e., the second slot segment 114 defines the shape and extension direction of the second cleaning segment 122.

[0032] In the embodiment, the circumferential distance d1 between the first swing portion 124 and the second swing portion 126 is equally arranged at different axial positions (such as the axial position p1 and the axial position p2), and the circumferential distance d1 is formed on the circumferential surface 111 of the body 110, i.e., the circumferential distance d1 is the length of an arc. In other words, the first swing portion 124 and the second swing portion 126 are oppositely arranged in terms of shape and extension direction, and the circumferential swing effect of the axially overlapped part is good, and the unwinding effect is better. It can be understood that in other embodiments, the circumferential distance d1 between the first swing portion 124 and the second swing portion 126 can be unequally arranged at different axial positions (such as the axial position p1 and the axial position p2).

[0033] Further, the projections of the first swing portion 124 and the second swing portion 126 on the body 110 are arranged in parallel, i.e., the projections of the first swing portion 124 and the second swing portion 126 on the body 110 are parallel straight lines, which can further improve the circumferential swing effect of the axially overlapped part and is beneficial to the migration of the winding on the first swing portion 124 and / or the second swing portion 126. It should be noted that in other embodiments, the projections of the first swing portion 124 and the second swing portion 126 on the body 110 are in the form of wavy lines, curves or other suitable shapes, rather than parallel arrangement.

[0034] In the embodiment, the first cleaning portion 123 and the second cleaning portion 125 are both arranged in the form of a spiral, and the spiral directions (extension directions) of the two are opposite (intersected), so that the first brush strip 120 as a whole presents a shape as shown in the following figure. Figure 3The first cleaning section 123 and the second cleaning section 125 are both in a spiral shape. The overall roundness of the first brush strip 120 is increased, the cleaning effect of small particles of garbage is improved, and the winding object can be guided to the first swing section 124 and the second swing section 126 from both ends of the main body 110. It can be understood that in other embodiments, the first cleaning section 123 and the second cleaning section 125 can be in a straight oblique shape, and the extension directions of the two can be the same or opposite (intersecting). It should be noted that in this application, "spiral shape" means that the extension direction is obliquely intersected with the axial direction, and the projection on the main body 110 is in a spiral line shape. "Straight oblique shape" means that the extension direction is obliquely intersected with the axial direction, and the projection on the main body 110 is in a straight line shape. The "flat straight shape" described below means that the extension direction is parallel to the axial direction, and the projection on the main body 110 is in a straight line shape.

[0035] In this embodiment, the projections of the first swing section 124 and the second swing section 126 on the main body 110 are in a flat straight shape, that is, the extension directions of the first swing section 124 and the second swing section 126 are parallel to the axial direction. At this time, the circumferential swing amplitude of the part where the first swing section 124 and the second swing section 126 overlap in the axial direction is the largest, and the winding object on the first swing section 124 and the second swing section 126 can be easily loosened, and the anti-winding effect is the best. It should be noted that the corner α1 of the first cleaning section 121 is the angle between the center line of the first cleaning section 123 and the center line of the first swing section 124. The center line of the first cleaning section 123 can be the center line of the spiral line formed by its projection on the main body 110, and the center line of the first swing section 124 can be a straight line formed by its projection on the main body 110. Correspondingly, the corner α2 of the second cleaning section 122 is the angle between the center line of the second cleaning section 125 and the center line of the second swing section 126. The center line of the second cleaning section 125 can be the center line of the spiral line formed by its projection on the main body 110, and the center line of the second swing section 126 can be a straight line formed by its projection on the main body 110.

[0036] In this embodiment, the first swing section 124 and the second swing section 126 both pass through the axial middle part of the main body 110, that is, through the center line L perpendicular to the axis. The winding object can be gathered towards the axial middle part of the main body 110, and the suction port in the roll brush cavity of the surface cleaning equipment is matched with the suction force to make the winding object on the first swing section 124 and the second swing section 126 more easily separated, the anti-winding effect is better, the automatic cleaning of the winding object is realized, and the user does not need to manually operate, further improving the user experience. It can be understood that the first swing section 124 and the second swing section 126 can be arranged at other positions of the main body 110, and can also realize circumferential swing, and the suction force of the suction port in the roll brush cavity can also act on the winding object.

[0037] It should be noted that, in other embodiments, in order to make the circumferential distance d1 between the first swing part 124 and the second swing part 126 unequally arranged at different axial positions (such as the axial position p1, the axial position p2), the projection of the first swing part 124 on the main body 110 is arranged in a straight manner, and the projection of the second swing part 126 on the main body 110 is arranged in an oblique manner; the projection of the first swing part 124 on the main body 110 is arranged in an oblique manner, and the projection of the second swing part 126 on the main body 110 is arranged in a straight manner; or when the extension directions of the first cleaning part 123 and the second cleaning part 125 are opposite, the projections of the first swing part 124 and the second swing part 126 on the main body 110 are both arranged in an oblique manner, and the extension directions are opposite (intersected).

[0038] Please refer to Figure 5 , Figure 5 The principle diagram of the first brush strip in the second embodiment of the rolling brush provided by the embodiment 1 of the present application is shown, and the rolling brush 100 in the present embodiment has the following differences from the rolling brush 100 in the above-mentioned first embodiment: The extension directions of the first cleaning section 121 and the second cleaning section 122 of the first brush strip 120 of the rolling brush 100 in the present embodiment are the same, that is, the first cleaning part 123 and the second cleaning part 125 are both arranged in a spiral manner and have the same spiral direction, and the projections of the first swing part 124 and the second swing part 126 on the main body 110 are both arranged in a straight manner, so that the first brush strip 120 as a whole is arranged in a spiral manner. The winding object will migrate from one end of the rolling brush 100 to the other end, and when passing through the first swing part 124 and the second swing part 126, the first swing part 124 and the second swing part 126 can also achieve the technical effects of the above-mentioned first embodiment.

[0039] As for other aspects of the rolling brush 100 in the present embodiment, they are basically the same as those of the rolling brush 100 in the above-mentioned first embodiment, and the specific contents can be referred to the description of the above-mentioned first embodiment, which will not be repeated here.

The winding object will migrate from one end of the rolling brush 100 to the other end, and when passing through the first swing part 124 and the second swing part 126, the first swing part 124 and the second swing part 126 can also swing circumferentially, thereby achieving the effect of preventing winding.

[0041] In this embodiment, the first cleaning part 123 and the second cleaning part 125 are both in spiral shape and have the same spiral direction, so that the first brush strip 120 is in spiral shape as a whole. It can be understood that, in other embodiments, the first cleaning part 123 and the second cleaning part 125 can both be in oblique straight shape instead of spiral shape; the first cleaning part 123 is in spiral shape and the second cleaning part 125 is in oblique straight shape; or the first cleaning part 123 is in oblique straight shape and the second cleaning part 125 is in spiral shape.

[0042] As for other aspects of the rolling brush 100 of this embodiment, they are basically the same as those of the rolling brush 100 of the first embodiment described above, and the specific content can be referred to the description of the first embodiment, which will not be repeated here.

The shaft body 115 is in rigid structure, and the inner core 116 is in flexible material, which can be but is not limited to polyurethane (PU). Figure 7 In this embodiment, the rolling brush 100 further includes a plurality of second brush strips 140, each of which is located between two adjacent first brush strips 120 and is directly arranged on the circumferential surface 111 of the sleeve 117. The materials of the sleeve 117, the first brush strip 120 and the second brush strip 140 can be but are not limited to soft rubber, and other materials with flexible elasticity can also be used. Moreover, the sleeve 117, the first brush strip 120 and the second brush strip 140 are integrally formed. The second brush strip 140 is in the shape of a blade, but is not limited to this shape.

[0044] In combination with

[0045] In combination with Figure 10 ​In the embodiment, the length l1 of the second brush strip 140 extending radially from the circumferential surface 111 of the main body 110 is less than the length l2 of the first brush strip 120 extending radially from the circumferential surface 111 of the main body 110. Since the second brush strip 140 has a shorter radial length, it has a certain structural strength and can roll in larger dirt, preventing the leakage of large-particle garbage and improving the cleaning capacity of large-particle garbage. The first brush strip 120 with a longer length cannot withstand larger particles due to disconnection. Moreover, the second brush strip 140 can avoid contacting the ground, and will not produce noise during operation, which is conducive to reducing the noise of the rolling brush 100 during operation.

[0046] In the embodiment, each second brush strip 140 includes a third cleaning part 142, a connecting part 144, and a fourth cleaning part 146 connected in sequence. The third cleaning part 142 is arranged corresponding to the first cleaning part 123, the connecting part 144 is arranged corresponding to the first swing part 124 and the second swing part 126, and the fourth cleaning part 146 is arranged corresponding to the second cleaning part 125. The projections of the third cleaning part 142 and the fourth cleaning part 146 on the main body 110 are arranged in a spiral shape, which increases the overall roundness of the second brush strip 140 and facilitates rolling in larger particles. The projection of the connecting part 144 on the main body 110 is arranged in a straight shape, i.e., parallel to the projections of the first swing part 124 and the second swing part 126 on the main body 110.

[0047] Further, the spiral direction of the third cleaning part 142 intersects with the spiral direction of the fourth cleaning part 146, so that the second brush strip 140 as a whole presents an inverted trapezoidal or swallowtail shape as shown in Figure 9 When sweeping, garbage will move towards the middle of the second brush strip 140, which is convenient for being sucked into the suction port and improves the cleaning effect. It can be understood that in other embodiments, each second brush strip 140 can be V-shaped, i.e., each second brush strip 140 includes two connected parts, one part corresponding to the first cleaning part 123 and the other part corresponding to the second cleaning part 125. It should be noted that the second brush strip 140 cooperates with the first brush strip 120, and in order to improve the cleaning effect, the shape and extension direction of the second brush strip 140 are arranged corresponding to the shape and extension direction of the first brush strip 120.

[0048] In the embodiment, the circumferential distance d1 formed between the first swing part 124 and the second swing part 126 is less than the circumferential distance d2 formed between the first swing part 124 and the adjacent connecting part 144, and less than the circumferential distance d3 formed between the second swing part 126 and the adjacent connecting part 144. As shown in Figure 10As shown, the central angle θ1 formed between the first swing portion 124 and the second swing portion 126 is smaller than the central angle θ2 formed between the first swing portion 124 and the adjacent connecting portion 144, and smaller than the central angle θ3 formed between the second swing portion 126 and the adjacent connecting portion 144.

[0049] Since the circumferential distance d1 between the first swing portion 124 and the second swing portion 126 is small, i.e. the distance between the first cleaning section 121 and the second cleaning section 122 is small, when the first brush strip 120 contacts the ground, a larger pressure difference can be formed at the suction port in the roller brush cavity, so that fine dirt can be cleaned, thereby improving the cleaning ability of soft ground. Since the circumferential distances d2, d3 between the swing portion and the connecting portion 144 are large, i.e. the distance between the adjacent first brush strip 120 and the second brush strip 140 is large, larger particles of dirt can be contained and rolled to the suction port to be sucked in. When the first brush strip 120 and the second brush strip 140 rotate respectively with the suction port in the roller brush cavity, when the longer first brush strip 120 contacts the ground, the suction in the roller brush cavity will be larger; when the shorter second brush strip 140 passes (without contacting the ground), the suction in the roller brush cavity will be smaller, thereby achieving the effect of alternating suction, ensuring the cleaning applicability of large and small particles of garbage, enhancing the cleaning ability of soft ground, and improving the cleaning effect.

[0050] In this embodiment, the circumferential distance d2 between the first swing portion 124 and the adjacent connecting portion 144 is equal to the circumferential distance d3 between the second swing portion 126 and the adjacent connecting portion 144. Obviously, in other embodiments, the two can be set unequally.
