Referring to fig. 1, 6 and 7, a rolling brush according to an embodiment of the present invention includes a rolling brush body 100, wherein a plurality of segments of protruding strips 220 are circumferentially spaced on an outer circumferential surface of the rolling brush body 100, and the protruding strips 220 protrude from the outer circumferential surface of the rolling brush body 100. The projection of the convex strips 220 on the outer circumferential surface in the radial direction of the rolling brush body 100 (the projection direction shown in fig. 6) forms a projection area. The outer peripheral surface of the rolling brush body 100 is developed to form a developed surface as shown in fig. 7, on the developed surface, the projection areas of two adjacent convex strips 220 in the circumferential direction of the rolling brush body 100 overlap at least partially in the axial direction of the rolling brush body 100, and the T area shown in fig. 7 is the overlapping area.

Referring to fig. 6, when the roller brush cleans a soft cleaning surface such as a carpet 420, the raised strips 220 are embedded between the piles of the carpet 420 due to the large amount of piles on the surface of the carpet 420 and the gaps between the piles. When the round brush rotates, carpet 420 can be patted in succession to multistage sand grip 220, makes rubbish dust etc. raise to, sand grip 220 can produce the deformation, and in its the twinkling of an eye with carpet 420 separation, sand grip 220 reconversion to the helping hand that raises upwards is produced rubbish dust etc.. In addition, when cleaning in-process certain period of time, two sections adjacent sand grips 220 all contact with the fine hair of carpet 420 and support tightly, between the fine hair of soft cleaning surfaces such as sand grip 220 embedding carpet 420, fine hair blocks sand grip 220 width direction ascending both ends with the external world, can form a comparatively confined space between adjacent sand grip 220 and the fine hair in the week of the round brush body 100, along with the suction of the suction piece that the cooperation was used on the dust catcher, the atmospheric pressure that can make this space slightly is less than external atmospheric pressure. In the twinkling of an eye that the round brush rolled to one of them section sand grip 220 and carpet 420 and separated, external atmospheric pressure was greater than the atmospheric pressure in the space, can help inhaling the dust, made on rubbish dust etc. attached to the round brush, more easily promoted, and then sucked to, at above-mentioned atmospheric pressure change in-process, soft cleaning surface such as carpet 420 probably takes place slight shake because of pressure differential, also is favorable to raising dust etc..

In addition, the radial direction along the rolling brush body 100 referred to in the above-described projection direction may be a direction inclined with respect to the outer peripheral surface of the rolling brush body 100, in addition to the radial direction in the conventional sense (i.e., the direction perpendicular to the outer peripheral surface of the rolling brush body 100).

The roll brush body 100 is preferably cylindrical, and the outer peripheral surface thereof is a cylindrical surface. As such, it has less resistance as it rolls. Moreover, the cylindrical processing and manufacturing difficulty is lower. Of course, it may be polygonal, for example, dodecagonal or icogonal, and the rolling resistance is larger than that of a cylindrical shape, but when the number of sides is large, the rolling resistance can be approximated to the cylindrical shape.

The rolling brush can be used in a dust collector, the rolling brush body 100 is connected with a motor of the dust collector, and the rolling brush body 100 is driven to rotate by the motor, so that garbage, dust and the like on the ground are lifted, and the garbage can be sucked into a garbage bin by a suction piece easily.

Preferably, the protruding strips 220 have high elasticity and wear resistance and high strength. Preferably, the protruding strip 220 is made of a flexible material such as rubber, for example, TPU or TPE. Thus, when cleaning a soft cleaning surface such as the carpet 420, the soft cleaning surface is less likely to be scratched or damaged.

In the embodiment shown in fig. 1 and 7, the projection areas of two convex strips 220 adjacent in the circumferential direction of the rolling brush body 100 partially overlap in the axial direction of the rolling brush body 100, and the T area shown in fig. 7 is the overlapping area. When partially overlapped, the plurality of ribs 220 may be spirally distributed on the outer circumferential surface of the rolling brush body 100. Alternatively, in other embodiments, the plurality of ribs 220 may be distributed in a "V" shape on the outer circumferential surface of the rolling brush body 100. Alternatively, in other embodiments, the plurality of ribs 220 may be distributed in a "W" shape on the outer circumferential surface of the rolling brush body 100. Alternatively, in other embodiments, the plurality of ribs 220 may be distributed in an "M" shape on the outer circumferential surface of the rolling brush body 100. The "M" shape can be viewed as an inverted "W" shape. When the shape is set as described above, the area of the outer peripheral surface of the brush roll 100 where the convex strips 220 are distributed in the axial direction is large, and the cleaning range is wider.

Referring to fig. 8 and 9, in other embodiments, the projections of two segments of the protruding strips 220 adjacent to each other in the circumferential direction of the rolling brush body 100 in the axial direction of the rolling brush body 100 completely coincide with each other. A plurality of rows of ribs 220 are provided along the axial direction of the rolling brush body 100, and both ends of each row of ribs 220 are aligned. At this time, the functions in the foregoing embodiments can also be realized.

Referring to fig. 1 and 7, in some embodiments, the width direction of the protruding strips 220 is parallel to the axial direction of the rolling brush body 100. At this time, the dust and the like are caught between the outer side walls of the adjacent convex strips 220 and are lifted. Alternatively, in other embodiments, on the developed surface of the rolling brush body 100, the width direction of the convex strip 220 is perpendicular to the axial direction of the rolling brush body 100. At this time, the dust and the like are caught between the end walls of the adjacent convex strips 220 and are lifted. Alternatively, in other embodiments, the width direction of the protruding strip 220 on the expansion surface of the rolling brush body 100 forms an acute angle with the axial direction of the rolling brush body 100. At this time, the dust and the like are caught between the outer side walls of the adjacent convex strips 220 and are lifted.

Referring to fig. 1 to 3, in some embodiments, the sealing members are disposed on the outer circumferential surface of the rolling brush body 100, and the sealing members are disposed at both ends of the protruding strip 200 in the axial direction of the rolling brush body 100. Two adjacent closing members and the raised strip 220 between the two closing members can form a semi-closed space and contact with the soft cleaning surface such as the carpet 420, so that the sealing performance between the soft cleaning surface such as the carpet 420 is better.

As described above, when cleaning a cleaning surface such as a carpet 420, two adjacent convex strips 220 are in contact with and abut against the carpet 420, and the sealing members at both ends of the convex strip 220 can seal the end regions of the convex strip 220, so that the sealing property of the space between the cleaning surface such as the carpet 420 and the suction member used in conjunction with the cleaner is improved. In the twinkling of an eye at sand grip 220 and the separation of carpet 420, stronger to the adsorption affinity that the dust produced, dust is changeed in being kicked up and is adsorbed, and carpet 420 is more violent at the shake that this in-process took place, changes in kicking up dust etc. is favorable to the reinforcing to clean the dynamics, makes to clean more thoroughly.

Specifically, the closure may be a lint 300. The soft bristle part 300 and the protruding strip 200 are spaced apart from each other in the axial direction of the brush roller 100. During cleaning, the soft bristles 300 located at both ends of the protruding strip 220 can close the end regions of the protruding strip 220.

Preferably, the soft hair part 300 may be a flocked fabric, which is cut according to the size of the roll brush body 100 and then is adhered to and wrapped around the outer circumferential surface of the roll brush body 100.

Referring to fig. 5 and 6, when the roller brush cleans a hard cleaning surface such as a floor 410, the soft hair part 300 can stick and roll up dust and dirt on the floor 410, so that the dust and dirt can be easily sucked into the garbage bin.

When the rolling brush is used, hard cleaning surfaces such as the floor 410 and the like can be cleaned, soft cleaning surfaces such as the carpet 420 and the like can be cleaned, and the rolling brush does not need to be replaced, so that the rolling brush is convenient to use. Further, since one brush can be used for multiple purposes, the number of parts can be reduced, and the cost can be reduced. In addition, when cleaning a soft cleaning surface such as a carpet, the convex strips 220 are not easy to scrape and damage the soft cleaning surface, and the cleaning force is strong.

In some embodiments, the height of the bristles 300 protruding from the outer circumferential surface of the rolling brush body 100 is greater than the height of the protrusions 220 protruding from the outer circumferential surface of the rolling brush body 100.

Because the outer peripheral surface of the rolling brush body 100 is provided with the soft hair part 300 and the convex strip 220, and the convex strip 220 is lower than the soft hair part 300; in a specific application scenario, when the roller brush cleans a hard cleaning surface such as the floor 410, only the bristles 300 contact the floor 410, and the ridges 220 are in a non-operating state and do not contact the floor 410. When the roll brush rotates, the soft bristles 300 lift up the garbage, etc. on the floor 410. Since the rib 220 does not contact the floor 410, noise of beating the floor 410 is not generated.

When the soft hair part 300 is higher than the protrusion 220, the rolling brush 100 is pressed when the carpet 420 is cleaned, the soft hair part 300 and the carpet 420 are pressed tightly, and the protrusion 220 is embedded in the carpet 420. So, the tip of sand grip 220 is separated with the external world by soft hair portion 300 completely, and the closure in the space that forms between the soft hair portion 300 of adjacent sand grip 220, both ends department and carpet 420 is better, and in the twinkling of an eye of sand grip 220 and carpet 420 separation, the dust is changeed in being kicked up and is adsorbed, is favorable to the reinforcing to clean the dynamics, makes to clean more thoroughly. And, some garbage with a slightly larger volume can be temporarily stored in the space formed between the adjacent protruding strips 220, the soft hair parts 300 at the two ends and the carpet 420, and reaches the suction opening of the suction piece along with the rolling of the rolling brush, and then is sucked into the garbage bin.

If the height difference between the soft bristle part 300 and the protrusion 220 is too large, the protrusion 220 may not sufficiently contact with the pile of the carpet when cleaning a soft cleaning surface such as a carpet, and the cleaning force is weak, which may cause incomplete cleaning. If the height difference between the soft bristle part 300 and the protrusion 220 is too small, when a hard cleaning surface such as a floor is cleaned, the protrusion 220 may come into contact with the hard cleaning surface and flap the hard cleaning surface, which may cause noise during cleaning.

Therefore, the height difference between the fur portion 300 and the protruding strip 220 is required to be within a proper range to ensure a good cleaning force and a low noise. Referring to fig. 5, preferably, the difference h between the height of the soft bristle part 300 protruding from the outer circumferential surface of the rolling brush body 100 and the height of the protrusion 200 protruding from the outer circumferential surface of the rolling brush body 100 is in the range of 0.5mm ≦ h ≦ 1.5 mm.

Specifically, in some embodiments, the height of the bristles 300 protruding from the outer circumferential surface of the rolling brush body 100 is 23.5mm, and the height of the end of the rib 200 protruding from the outer circumferential surface of the rolling brush body 100 is 22 mm.

Further, the width of the fur portion 300 and the width of the convex strip 220 are also required. If the width of the pile portion 300 is too large and the width of the ridge 220 is too small, cleaning force may be poor when cleaning a soft cleaning surface such as a carpet. On the other hand, if the width of the soft bristles 300 is too small and the width of the ridges 220 is too large, cleaning power may be poor when cleaning a hard cleaning surface such as a floor.

Therefore, the ratio of the width of the protruding strip 220 to the width of the soft bristle part 300 should be in a proper range so that the cleaning force of the roller brush for both hard and soft cleaning surfaces is good. Referring to fig. 7, it is preferable that the ratio of the width D of the protruding strip 220 to the width D of the fur portion 300 is in the range of 0.2 ≦ D/D ≦ 0.3.

Specifically, in some embodiments, the width D of the protruding strip 220 is 10mm, the width D of the fur portion 300 is 40mm, and D/D is 0.25.

Of course, if a large number of rollers are used to clean a hard cleaning surface such as a floor, the width of the soft bristle part 300 can be increased as appropriate, and if a large number of rollers are used to clean a soft cleaning surface such as a carpet, the width of the ridge 220 can be increased as appropriate.

In other embodiments, the closing member may be a sponge portion; the arrangement of the sponge part on the roll brush body 100 may be the same as that of the soft hair part 300 described above.

Referring to fig. 3, 4 and 6, in some embodiments, the protruding strip 220 includes a main body portion 221, an intermediate portion 222 and a contact portion 223. One end of the intermediate portion 222 is connected to the body portion 221, and the other end is connected to the contact portion 223. The body 221 is connected to the convex strip connecting portion 210. When cleaning a soft cleaning surface such as a carpet 420, the contact portion 223 is mainly fitted into a pile gap of the carpet 420. When the roller brush rotates, mainly the intermediate portion 222 deforms.

Preferably, the thickness of the middle portion 222 is smaller than the thickness of the body portion 221 and the contact portion 223. The thickness direction is a direction tangential to the rotation direction of the roll brush shown in fig. 6. Since the body 221 is used to connect to the protruding strip connection portion 210, the greater the thickness, the higher the connection strength, and the less likely it will break during cleaning. The contact portion 223 is a main portion that contacts the cleaning surface, and is likely to directly contact and collide with a hard obstacle during cleaning. The greater the thickness of the contact portion 223, the less likely it is to be damaged by collision, and the stronger the beating action on the carpet, making it easier for dust to be kicked up and sucked. As shown in fig. 6, when the roller brush rolls, the convex strip 220 is deformed, and the main deformed portion is the middle portion 222. If the width of the intermediate portion 222 is large, deformation is difficult to occur. The width of the intermediate portion 222 is set to be small, which is beneficial to deformation of the intermediate portion so as not to cause breakage between the body portion 221 and the ridge connecting portion 210 due to failure in deformation. Of course, in some embodiments, the main body 221, the intermediate portion 222, and the contact portion 223 may have equal thicknesses, that is, the cross-sectional shape may be rectangular, or the cross-sectional shape may be a positive direction, or may be an irregular shape.

Preferably, the end surfaces of the contact portions 223 are smoothly transitioned. The end surface of the contact portion 223 may be in the form of a sharp corner, but a smooth transition can reduce friction of the end surface of the contact portion 223 against a soft cleaning surface such as a carpet, and prolong the service life of the soft cleaning surface such as a carpet, as compared to a sharp corner.

Preferably, the end surface of the contact portion 223 is arc-shaped, so as to reduce the difficulty in production and manufacture.

Preferably, the outer surface of the rib 220 is smooth at the locations where the dimension changes, for example, the outer surface may be rounded at these locations to reduce friction against the soft cleaning surface such as a carpet and to extend the service life of the soft cleaning surface such as a carpet.

In other embodiments, the ribs 220 may be provided in other shapes. For example, the contact portion 223 has a spherical shape or an ellipsoidal shape.

If the distance between the adjacent ribs 220 is too large, the cleaning capability may be insufficient, and if the distance between the adjacent ribs 220 is too small, the dust may be deposited between the adjacent ribs 220, which is not easy to clean, and the manufacturing cost may be too high.

Therefore, the pitch between the adjacent ribs 220 should be within a suitable range. Referring to FIG. 7, preferably, the interval L between the adjacent protrusions 220 ranges from 6mm L9 mm.

Preferably, the adjacent ribs 220 have the same pitch, so that the cleaning force of each region can be uniform during cleaning.

Referring to fig. 1 to 3, in other embodiments, the rib connecting portion 210 is fixed on the outer circumferential surface of the rolling brush body 100, a plurality of segments of ribs 220 are disposed on the rib connecting portion 210, and the ribs 220 are attached to the rolling brush body 100 through the rib connecting portion 210. In other embodiments, the material of the rib connecting portion 210 may be rubber, and is preferably the same as the material of the rib 220. Thus, the convex strip connecting portion 210 and the convex strip 220 are integrally formed, the manufacture is more convenient, the convex strip 220 and the convex strip connecting portion 210 are not easy to break and separate, and the strength is higher.

When the ribs 220 are distributed in a spiral shape, a V shape, or the like, the ribs 220 are integrally connected to the rib connecting portion 210, and the rib connecting portion 210 may be formed in a corresponding shape. Thus, the multi-segment protruding strips 220 can be fixed only by fixing the protruding strip connecting portions 210 on the rolling brush body 100, and the operation is convenient. When the ribs 220 are arranged as shown in fig. 8 and 9, a plurality of rib connecting portions 210 are required, and a plurality of segments of ribs 220 are connected to each rib connecting portion 210. The plurality of bead connecting portions 210 are distributed in the axial direction of the brush body 100.

Referring to fig. 1 to 3, preferably, an installation groove 110 is formed on an outer circumferential surface of the rolling brush body 100, a shape and a size of the installation groove 110 are matched with those of the protruding strip connection portion 210, and the protruding strip connection portion 210 is inserted into the installation groove 110. The mounting groove 110 can limit the protruding strip connecting portion 210, so that the protruding strip connecting portion and the rolling brush body 100 can be more firmly fixed and are not easy to shift. The protruding strip connecting portion 210 can be fixed by the above-mentioned snap-fit method. The roller brush body 100 can be fixed by rubber coating, or can be formed into a whole by injection molding, or can be fixed by bonding. Or, the two are fixed by clamping and bonding at the same time.

Referring to fig. 10, in some embodiments, the rib connecting portion 210 is integrally formed with the rolling brush body 100 by encapsulation or injection molding. The soft hair part 300 is bonded and fixed to the roll brush body 100.
