The novel rolling brush for the cleaning equipment provided by the embodiment of the invention cleans garbage on the ground, such as dust, hair and the like, through rotation. Referring to fig. 1, the roll brush includes a main brush body 100, a blade 200, and a bristle bar 300, wherein the main brush body 100 is cylindrical, and a through hole 120 is formed in the main brush body 100; a plurality of blades 200 are provided, wherein the blades 200 are spirally fixed to the surface of the main brush body 100 in the axial direction of the roll brush; one side of the top wool 300 is provided with a plurality of bristles 310, and the other side is fixedly connected with a part of the blades 200.

In actual use, the main brush body 100 is rotated to clean the floor, specifically, referring to fig. 2, the main brush body 100 is rotated along arrow a, and during the rotation of the main brush body 100, the blade 200 contacts with the floor and sweeps dust into the interior of the sweeping robot, and the dust is sucked away through a dust suction port (not shown in the drawing) of the sweeping robot.

In the cleaning process, long and thin garbage such as hair contacts the blades 200 and is rotated by the blades 200, and the spiral blades 200 can guide the garbage to slide to both ends of the main brush body 100 along the blades 200, specifically, both ends of the blades 200, during the rotation of the main brush body 100, so that the rolling brush can guide the garbage to both ends of the main brush body 100 for collection and treatment.

During the process of cleaning the ground, the wool tops 300 on the blades 200 can have the following two functions during the cleaning process:

1. the brush bristles 310 directly contact with the garbage on the ground, and the garbage is swept up by matching with the blades 200 while the main brush body 100 rotates, and finally the garbage is sucked away by the sweeping robot;

2. the bristles 310 rub against the ground to generate static electricity, the bristles 310 generating the static electricity can adsorb garbage with light weight and certain length, such as short hair, so that the short hair is adhered among the bristles 310, and finally the short hair is sucked away by the sweeping robot.

The wool tops 300 are combined with the blades 200 on the rolling brush, when the rolling brush rotates and cleans the ground, the plurality of bristles 310 are in contact with the ground, and the short hairs are left on the wool tops 300 until the short hairs are sucked away by the sweeping robot, so that the short hairs on the ground are effectively cleaned, and the cleaning quality is improved.

In summary, the novel rolling brush for cleaning equipment according to the embodiment of the present invention utilizes the blades 200 spirally distributed on the surface of the main brush body 100, so that when the blade 200 rotates and cleans the ground, slender garbage such as hair on the ground can be guided to move towards the two ends of the main brush body 100, and meanwhile, in cooperation with the bristles 300 on the blades 200, a plurality of bristles 310 on the bristles 300 rub against the ground to generate static electricity, so that short hair is adsorbed on the bristles 310 by the static electricity, thereby effectively cleaning hair of all lengths on the ground, and improving the cleaning quality.

It should be mentioned that in the roll brush according to the embodiment of the present invention, the surface fixed to the roll brush spirally in the axial direction of the roll brush may be implemented in two ways:

1. the main brush body 100 and the blade 200 are integrally formed, and are processed at one time by a mould through injection molding and other processes in the production process, so that the embodiment can facilitate the production, reduce the cost investment, reduce the procedures required by assembly and improve the production efficiency;

2. the main brush body 100 and the blades 200 are separated from each other, during the production process, the main brush body 100 and the blades 200 are respectively manufactured by different molds, and after the processing, the plurality of blades 200 are assembled on the main brush body 100 in a fixing mode including, but not limited to, clamping and welding, and this embodiment can facilitate the user to replace the damaged blades 200 on the main brush body 100.

Referring to fig. 1, further, in order to better guide elongated debris such as hairs to the both ends of the main brush body 100 in use, the blades 200 extend from one end of the main brush body 100 to the other end of the main brush body 100. In practical use, as the main brush body 100 rotates, the plurality of blades 200 alternately contact the ground to clean the garbage, and the elongated garbage such as hair slides along the blades 200 of the main brush body 100 to both ends of the main brush body 100 to be sucked away for cleaning.

In other embodiments, the blades 200 may also be discontinuous (not shown in the drawings), that is, the blades 200 on the main brush body 100 do not extend from one end of the main brush body 100 to the other end of the main brush body 100, the blades 200 on the main brush body 100 may extend from the end of the main brush body 100 to the middle of the main brush body 100, and two adjacent blades 200 extend from the opposite ends and extend to the middle of the main brush body 100. In this embodiment, long and thin garbage such as hair can still slide to both ends of the main brush body 100 by contacting the spiral blades 200, so as to clean all garbage on the ground.

During the cleaning process, as the main brush body 100 rotates, specifically, referring to fig. 2, rotating along arrow a, one of the surfaces of the blade 200 will directly contact with the ground, it can be understood that the surface directly contacting with the ground is the cleaning surface 210 of the blade 200 for cleaning, wherein, in the cross section of the main brush body 100, the blade 200 is obliquely arranged towards the side far away from the cleaning surface 210.

In practical use, the rolling brush rotates in a direction opposite to the inclination direction of the blade 200, the cleaning surface 210 directly contacts with the ground during the rotation and carries up the garbage on the ground, wherein fine garbage such as dust is sucked into the cleaning robot during the rolling process of the main brush body 100, and slender garbage such as hair has a part of residual garbage which is not sucked away, and the garbage can move to the two ends of the blade 200 along the blade 200, in this embodiment, referring to fig. 1 and 5, the garbage can move to the two ends of the main brush body 100 and be intensively treated.

It should be mentioned that the inclined blades 200 can make the cleaning surface 210 contact with the ground sufficiently during the rotation of the main brush body 100, and can clean the dust, hair and other garbage, thereby improving the cleaning effect.

It should be noted that the effect of guiding the slender garbage such as hair is limited only by the guiding function of the spirally fixed blades 200, and in order to further improve the effect of cleaning the slender garbage such as hair, the cleaning surface 210 of some blades 200 is provided with a plurality of salient points 220; the sweeping surface 210 of the other part of the blade 200 is fixedly connected with the top wool 300.

In the cleaning surface 210 provided with the protruding points 220, a plurality of protruding points 220 are arranged in the extending direction of the blade 200. The arrangement of the salient points 220 can lead the slender garbage such as hair to generate a guiding effect in the process of wandering the surfaces of the blades 200, specifically, the main brush body 100 rotates to drive the blades 200 to alternately contact with the ground and sweep the garbage, and when the slender garbage such as hair is swept, the garbage can contact with the salient points 220 in the wandering process

Firstly, the convex points 220 can block the garbage, and prevent the garbage from falling out of the blades 200 and scattering to the ground again;

secondly, rubbish is in the in-process of wandering and bump 220 direct contact, and bump 220 can play the guide effect to rubbish to guide rubbish to wander along the edge of bump 220, the cooperation is spiral helicine blade 200, makes rubbish wander to the both ends of main brush body 100 and collects the clearance at main brush body 100 pivoted in-process.

As can be seen from the foregoing, the blade 200 directly contacts and collides with the ground during the rotation, and generates a lot of noise during the contact and collision with the ground, for this reason, the blade 200 includes the first blade 201 and the second blade 202, and the length of the first blade 201 is smaller than that of the second blade 202 on the cross section of the main brush body 100, so that the noise generated when the roller brush cleans the ground is reduced by the design, and the use feeling of the user is improved.

Specifically, in the cleaning process, long and thin garbage such as hair first contacts the first blade 201 and the second blade 202, and the first blade 201 and the second blade 202 rotate with the garbage, but in the rotation process of the main brush body 100, because the first blade 201 and the second blade 202 have a length difference, the contact amplitude of the first blade 201 and the second blade 202 with the ground is not consistent, and the noise generated by the contact with the ground is not consistent, specifically, the noise generated by the contact of the first blade 201 and the ground is less, and the first blade 201 and the second blade 202 which are not fixed in length are arranged on the surface of the main brush body 100, so that the noise generated when the roller brush cleans the ground is reduced, and the use feeling of a user is improved.

In addition, the main brush 100 also vibrates the first blade 201 and the second blade 202 during the rotation, and the noise caused by the vibration of the shorter first blade 201 is smaller than that of the longer second blade 202.

In contrast, the second blade 202 has a better cleaning effect than the first blade 201, and if the short blade 200 is used to reduce noise, the cleaning effect is sacrificed, so the top wool 300 is fixedly connected only to the first blade 201. The noise caused by the rotation of the rolling brush can be reduced while the ground cleaning effect is ensured.

Further, the distances between the adjacent first blade 201 and second blade 202 are equal. The distance of first blade 201 and the second blade 202 that the interval set up, its range is equal, and the arrangement that the distance is equal enables whole round brush and tends towards stably at the pivoted process, makes whole robot work of sweeping the floor more smooth-going, improves the effect of cleaning.

In addition, the stable working state can reduce the running vibration of the whole sweeping robot to the minimum, thereby effectively reducing the noise generated by the sweeping robot in the actual work.

The first blade 201 collides with the ground while rotating along with the main brush body 100, and the first blade 201, which has a short length, is more easily damaged than the second blade 202 in a long-term use, and for this reason, the first blade 201 has a thickness greater than that of the second blade 202. The thickness of the first blade 201 is increased, the strength of the first blade 201 can be increased, and the first blade 201 is prevented from being damaged in practical use. In addition, the thickness of the first blade 201 is increased, and the vibration of the first blade 201 can be reduced, thereby reducing the noise generated during the rotation of the first blade 201.

Specifically, the thickness of the first blade 201 may be 2 times the thickness of the second blade 202. This embodiment is only one example of the roller brush of the present invention, and the remaining examples in which the thickness of the first blade 201 is greater than that of the second blade 202 should be considered as within the scope of the present invention.

It should be noted that referring to fig. 3 and 4, the bristles 310 are perpendicular to the surface of the wool top 300. The bristles 310 are perpendicular to the surface of the bristle bar 300, which can effectively improve the cleaning effect, and particularly, since the bristle bar 300 is snugly mounted on the blade 200, the bristles 310 are perpendicular to the surface of the blade 200, wherein when the blade 200 contacts with the ground and cleans the ground, all the bristles 310 are bent from an angle perpendicular to the ground to contact with the ground, and particularly, after the bristles 310 contact with the ground, a part of the garbage is swept up, and during the rotation process of the main brush body 100 with the blade 200, the bristles 310 return to a state perpendicular to the blade 200, wherein during the return process of the bristles 310, the bristles 310 fully contact with the ground and generate static electricity, thereby adsorbing short bristles on the ground and improving the cleaning effect of the whole sweeping robot.

In order to improve the sweeping effect and to effectively clean the floor, a plurality of bristles 310 are arranged on the surface of the cylindrical body in a matrix. Many brush hairs 310 can improve the efficiency of cleaning, clean simultaneously through many brush hairs 310 when making blade 200 and ground contact, and many brush hairs 310 are the matrix and arrange the effect region unanimous that cleans that can make each region on the wool top 300 more effectively, and in-process when blade 200 cleans ground, each region on messenger's monoblock blade 200 can both carry out effectual cleanness to ground, improves and cleans the effect.

In the above-described embodiment, it should be mentioned that the bristles 310 comprise hard plastic. The bristles 310 made of hard plastic can better rub against the ground to generate static electricity, thereby more effectively attracting the short hairs on the ground between the short hairs and thus sweeping the ground.

It should be noted that the above-mentioned driving mechanism is generally driven by a motor, and the rest of the driving mechanisms for providing driving force should also be regarded as the driving mechanisms mentioned in the embodiments of the present invention.

Most of the garbage that has migrated to both ends of the main brush body 100 is sucked and cleaned, but there is a portion that cannot be cleaned in time, and in order to prevent the portion that cannot be cleaned in time from falling into the environment again, the axial length of the sleeve 130 is shorter than the axial length of the main brush body 100, so as to form the clearance grooves 110 at both ends of the main brush body 100. Referring to fig. 6, when long and thin garbage such as hair moves to both ends of the main brush body 100 along the blades 200 of the main brush body 100, a part of the garbage is sucked away, the rest of the garbage is stored in the empty avoiding groove 110, after the cleaning is completed, a user can pour out the garbage in the empty avoiding groove 110 and perform centralized treatment, the empty avoiding groove 110 is provided to store the garbage which is not cleaned in time, the garbage is prevented from falling onto the ground again, and the cleaning effect is improved.

Further, a gap 140 is provided between the end cap 420 and the end faces of both ends of the main brush body 100. In order to prevent garbage from entering the clearance grooves 110 at both ends of the main brush body 100, referring to fig. 1, in a further modification of the above embodiment, a gap 140 is provided between the end cap 420 and the end surfaces at both ends of the main brush body 100. A gap 140 is left between the end cap 420 and the main brush body 100, which can provide a space for garbage to be guided in, specifically, when garbage moves on the blade 200 to the two ends of the main brush body 100 along the extending direction of the blade 200, part of the garbage which is not sucked can be guided into the clearance groove 110 through the gap 140 under the action of suction force for storage, so that part of the garbage can be conveniently centralized after cleaning.

Specifically, the gap 320 is a space formed by a certain distance between the end cap 300 and the end of the main brush body 100, which is the gap 320, without the end cap 300 and the end of the main brush body 100 contacting each other after the end cap 300 is assembled to the roll brush.

It should be noted that the end caps 420 are detachably mounted to both ends of the main brush body 100. The convenience of cleaning can be further improved, after cleaning is finished, the end cover 420 is directly detached, the garbage in the empty avoiding groove 110 can be completely poured out, and the end cover 420 is reassembled after the garbage is poured out.

The present invention is not limited to the above embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present disclosure should be included in the scope of the present disclosure as long as the technical effects of the present invention are achieved by the same means. Are intended to fall within the scope of the present invention. The invention is capable of other modifications and variations in its technical solution and/or its implementation, within the scope of protection of the invention.
