[0041] In the technical solution of the present invention, during the rotation of the roller brush 100, when the hair enters the end of the body 1, the guide surface 23 of the guide end cover 2 provides a force toward the middle of the body 1, driving the hair to move from the end of the body 1 toward the middle of the body 1, thereby preventing the hair from being entangled with the body 1 at the end of the body 1, thereby reducing the resistance to the rotation of the roller brush 100, and preventing the roller brush 100 from getting stuck, thereby preventing the end of the body 1 from being entangled with the hair, the motor driving the roller brush 100, etc., and melting due to continuous friction and temperature rise, thereby extending the service life of the roller brush 100 and the motor; the guide end cover 2 One or two may be provided, and the present invention does not impose any limitation on this. When one guide end cover 2 is provided, the guide end cover 2 is usually sleeved on one end of the main body 1 close to the driving member 300 to prevent the end of the main body 1 from melting due to continuous friction and heating with the hair, the motor driving the roller brush 100, etc. due to hair entanglement; when two guide end covers 2 are provided, the two guide end covers 2 are sleeved on both ends of the main body 1, so that the hair or foreign matter at both ends of the main body 1 are moved to the middle part of the main body 1; the guide surface 23 may be a plurality of spliced ​​inclined surfaces, or the entire guide surface 23 may be an arc-shaped inclined surface, and the present invention does not impose any limitation on this.

[0042] In order to handle foreign matter such as hair more efficiently and smoothly and prevent hair from getting stuck at the end of the body 1, please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the outer peripheral wall of the guide end cap 2 is arranged in an arc surface, and the cross-sectional area of ​​the guide end cap 2 gradually increases from one end close to the middle of the body 1 to one end far from the middle of the body 1. The outer peripheral wall of the guide end cap 2 is arranged in an arc surface, which helps to smoothly guide the hair to move to the middle of the body 1 and reduce the resistance encountered by the hair during the rotation process; the cross-sectional area of ​​the guide end cap 2 gradually increases from the position close to the middle of the body 1 to the position far from the middle, and this design can effectively form a guide channel, so that the hair is more easily guided to the middle of the body 1, further reducing the risk of entanglement and the stagnation of the hair during the guiding process, thereby improving the cleaning efficiency; the design of the arc surface and the gradually increasing cross-sectional area enhances the stability of the guide end cap 2 during operation, so that when the roller brush 100 rotates at high speed, it is not easy to vibrate or displace, thereby improving the reliability of the entire system.

[0043] Further, in order to reduce the contact area between the hair and the guide end cap 2, please refer to Figure 3In another embodiment of the present invention, a plurality of oblique edges 24 are formed at intervals on the outer peripheral wall of the guide end cover 2, and each of the oblique edges 24 extends from the end of the body 1 toward the middle of the body 1, and a groove 25 is formed between any two adjacent oblique edges 24, and the cross-sectional area of ​​each of the grooves 25 gradually increases from one end close to the middle of the body 1 to one end away from the middle of the body 1. The outer peripheral wall of the guide end cover 2 is spaced apart to form a plurality of oblique edges 24. This design can effectively reduce the contact area between the hair and the guide end cover 2, guide the hair to move toward the middle of the main body 1, thereby reducing the possibility of friction and entanglement; in another embodiment, the oblique edges 24 are relatively sharp and can directly cut off the hair. A groove 25 is formed between any adjacent oblique edges 24, which helps to accommodate and guide the cut hair to move toward the middle of the main body 1, while avoiding the accumulation of hair on the guide end cover 2. The cross-sectional area of ​​the bottom wall of each groove 25 gradually increases from a position close to the middle of the main body 1, so that the groove 25 can accommodate more hair and guide the hair to move toward the middle of the main body 1, further reducing the residence time of the hair on the end cover and improving the guiding efficiency; by providing the oblique edges 24 and designing the grooves 25, the hair is more likely to move along the guide end cover 2 to the middle position of the main body, significantly reducing the risk of entanglement, ensuring the smooth operation of the roller brush 100, optimizing the entire cleaning process, and enabling the sweeping robot to maintain an efficient cleaning effect when facing different ground surfaces and hair types.

[0044] For further information, see Figure 1In another embodiment of the present invention, the main body 1 includes two half shells 11 which are detachably connected and arranged in a mirror-symmetrical structure; each of the half shells 11 has a receiving groove, and the groove walls of the receiving grooves of the two half shells 11 enclose a receiving cavity that can accommodate the shearing mechanism 700; the outer wall of each half shell 11 is formed with a positioning protrusion 111 at the periphery of the notch of the receiving groove; the inner peripheral wall of the guide end cover 2 is provided with a positioning groove 21, and the two positioning protrusions 111 are accommodated and confined in the positioning groove 21. The body 1 is composed of two half shells 11. This design is not only convenient for production and assembly, but also can effectively reduce the weight of the overall structure and improve the flexibility of the equipment. The structure enclosed by the two half shells 11 can also effectively accommodate the shearing mechanism 700. This design makes the assembly and maintenance of the shearing mechanism 700 more convenient, and improves the overall maintainability and ease of use. The outer peripheral wall of each half shell 11 forms a positioning protrusion 111, and the inner peripheral wall of the guide end cover 2 is provided with a positioning groove 21. When the two half shells 11 are butt-jointed, the guide end cover 2 is sleeved at both ends of the body 1, and the positioning protrusion 111 can be accurately embedded in the positioning groove 21 to achieve the installation and positioning of the body 1 and the guide end cover 2, thereby ensuring a stable connection between the guide end cover 2 and the body 1, avoiding looseness during use, and ensuring that the guide end cover 2 and the body 1 can rotate synchronously. Such a setting not only makes the connection between the guide end cover 2 and the body 1 more stable, but also reduces the setting of some fasteners. In another embodiment, a through hole can be provided on the end face of the guide end cover 2, and the guide end cover 2 is screwed and fixed to the body 1 by passing a screw through the through hole.

[0045] The present invention also proposes a roller brush assembly, which includes a mounting seat 200, a driving member 300 and a roller brush 100. The specific structure of the roller brush 100 refers to the above embodiment. Since the roller brush assembly adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the mounting seat 200 is provided with a receiving groove 210 and a dust suction port 220, and the two ends of the body 1 are respectively rotatably connected to the two side walls opposite to the receiving groove 210; the output end of the driving member 300 is connected to one end of the body 1.

[0046] See also Figure 4 and Figure 5In the technical solution of this embodiment, the mounting seat 200 is provided with a receiving groove 210 and a dust suction port 220. The receiving groove 210 is used to collect garbage and dust generated during the cleaning process, and the dust suction port 220 can be connected to the dust suction system to enhance the cleaning effect; the two ends of the main body 1 are rotatably connected to the side walls opposite to the receiving groove 210. This design allows the roller brush 100 to rotate flexibly during cleaning, and can effectively adapt to the cleaning needs of different floors; the output end of the driving member 300 is connected to one end of the main body 1 to ensure that the roller brush 100 can rotate stably and continuously, thereby improving the working efficiency of the roller brush 100 and ensuring the thoroughness of cleaning.

[0047] To further prevent hair or foreign matter from entering the end of the body 1, refer to Figure 4 and Figure 5 In one embodiment of the present invention, the roller brush assembly includes a pressure cover 400 and a stopper 500. The pressure cover 400 is detachably connected to the mounting seat 200. The stopper 500 is provided on both ends of the pressure cover 400 facing the body 1. The provision of the stopper 500 effectively prevents hair or foreign matter from entering the receiving groove 210 through the end of the suction port 220 during the cleaning process, thereby preventing the hair from contacting the guide end cover 2, and further preventing the hair from getting entangled with the two ends of the body 1, reducing the risk of hair getting entangled and stuck with the ends of the body 1. By providing the stopper 500, the roller brush assembly can form an effective protective barrier when working, reducing the probability of failure caused by the entry of foreign matter, and improving the service life of the equipment; the pressure cover 400 is detachably connected to the mounting seat 200, and can be The pressure cover 400 and the mounting base 200 are screwed and fixed by passing screws through the pressure cover 400 and the mounting base 200, or a slot is set on the side of the mounting base 200 facing the pressure cover 400, and a buckle is set on the side of the pressure cover 400 facing the mounting cover, and the buckle is snapped into the slot. The present invention does not limit this. This design is convenient for maintenance and cleaning. The user can quickly disassemble the pressure cover 400 for cleaning as needed to ensure that the equipment maintains good performance for a long time; the stopper 500 can be a stop plate or a wool strip, and the present invention does not limit this.

[0048] See also Figure 4 and Figure 5In one embodiment of the present invention, the roller brush assembly includes a brush, the body 1 is provided with a plurality of installation grooves 12 at intervals, each of the brushes is arranged in one of the installation grooves 12, the guide end cover 2 is provided with a plurality of avoidance grooves 22 for avoiding the brushes, and some bristles of the brush extend out of the avoidance grooves 22 and protrude from the dust suction port 220. The roller brush assembly includes a plurality of brushes, each of which is arranged in a mounting groove 12 provided at intervals on the main body 1. When the driving member 300 drives the main body 1 to rotate, the plurality of brushes rotate with the main body 1 to sweep the debris or hair on the ground into the receiving groove 210 to be adsorbed by the adsorption mechanism provided on the main body; the guide end cover 2 is provided with a plurality of avoidance grooves 22, which are specifically used to avoid the brushes to ensure that the brushes can move freely without hindrance when the main body 1 rotates, thereby ensuring the comprehensiveness and smoothness of cleaning. Part of the bristles of the brush extend out of the avoidance groove 22 and protrude from the dust suction port 220. This design not only improves the effective reach of the brush, but also enhances the cleaning ability of the equipment, so that it can better capture and absorb dust and debris on the ground; by allowing the bristles of the brush to partially protrude from the dust suction port 220, the assembly can achieve deeper cleaning, especially in hard-to-reach corners and crevices, significantly improving the overall cleaning effect.

[0049] Further, in order to more effectively prevent hair or foreign matter from contacting the end of the guide end cap 2 and the end of the body 1, please refer to Figure 4 and Figure 5In one embodiment of the present invention, the stopper 500 is a wool strip, and the positive projection of the wool strip onto the guide end cover 2 shields the guide end cover 2. The stopper 500 adopts a wool strip design, and the structure of the wool strip can effectively cover the guide end cover 2. In this way, the wool strip can form a barrier to prevent hair and foreign matter from directly contacting the guide end cover 2, thereby reducing potential blockage and wear risks. The positive projection of the wool strip onto the guide end cover 2 shields the guide end cover 2, ensuring that during the operation of the device, even if a foreign matter approaches, it will be blocked by the wool strip first, thereby protecting the guide end cover 2 and the end of the body 1 from being affected; the design of the wool strip can not only reduce the distance between the stopper 500 and the outer peripheral wall of the guide end cover 2 to prevent hair or foreign matter from directly contacting the guide end cover 2, but also enable part of the bristles of the brush extending out of the avoidance groove 22 to push out part of the bristles of the wool strip, that is, the setting of the wool strip does not cause excessive interference with the end of the brush, but can further improve the ability to block foreign matter or hair; the wool strip is extended toward the center of the suction port 220 to reduce hair The friction between the wool strip and the outer peripheral wall of the guide end cover 2 reduces the rotational resistance and corresponding energy consumption of the roller brush 100, and also prevents the guide end cover 2 from melting due to excessive temperature; part of the bristles of the wool strip contacts the guide end cover 2, and during the rotation of the roller brush 100, part of the bristles of the wool strip contacts part of the bristles of the brush on the roller brush 100, which basically does not block or affect the rotation of the roller brush 100, and can also make the wool strip present a shape that fits the guide end cover 2 and the brush on the roller brush 100, thereby minimizing the invasion of hair into the end of the roller brush 100; the design of the wool strip can also enable hair and small particles in the cleaning process to be effectively captured when the brush is working, avoiding their accumulation near the guide end cover 2, thereby improving the overall cleaning performance and maintenance convenience, and by effectively blocking the contact of foreign matter, the wool strip not only protects the structural integrity of the guide end cover 2 and the body 1, but also extends the service life of the equipment, thereby improving the user experience.

[0050] In another embodiment, see Figure 3 and Figure 4 The outer peripheral wall of the guide end cover 2 is formed with a plurality of oblique edges 24 at intervals, and a groove 25 is formed between any two adjacent oblique edges 24, and the positive projection of the wool strip toward the guide end cover 2 shields the guide end cover 2; such a configuration also reduces the contact area between the guide end cover 2 and the wool strip, thereby reducing the friction, and the wool strip can extend into the groove 25, thereby better preventing hair from invading and winding around the guide end cover 2.

[0051] Further, to facilitate replacement of the stopper 500, please refer to Figure 4 and Figure 5In one embodiment of the present invention, the roller brush assembly includes a mounting bracket 600, the mounting bracket 600 is connected to the guide end cover 2, and the stopper 500 is detachably connected to the mounting bracket 600. The stopper 500 and the mounting bracket 600 are detachably connected, so that when the user needs to replace the stopper 500, it can be completed with a simple operation, saving time and effort, and reducing the difficulty of maintenance. This design enables the user to quickly replace the stopper 500 during use, avoiding the cleaning effect affected by the wear or dirt of the stopper 500, thereby improving the overall work efficiency of the equipment. The detachable connection method is not only convenient for replacement, but also simplifies the cleaning process. The user can regularly check and clean the stopper 500 to ensure that it is always in good condition.

[0052] The present invention also proposes a sweeping robot, which includes a shearing mechanism 700, an adsorption mechanism, and a roller brush assembly as described in any of the above embodiments, wherein the shearing mechanism 700 is movably arranged on the body 1; the adsorption mechanism is arranged on the body 1. The shearing mechanism 700 can effectively decompose long hairs to prevent them from being entangled in the roller brush assembly, thereby improving the cleaning efficiency; the adsorption mechanism is also arranged in the body 1, and is intended to suck the dust and fine particles generated during the cleaning process into the dust collection box through suction. This design ensures that the floor cleaning is more thorough, and works in conjunction with the roller brush assembly to achieve the best cleaning effect; the sweeping robot can adapt to a variety of floor materials by comprehensively utilizing the functions of shearing, adsorption, and the roller brush 100, and realize intelligent and efficient cleaning. During use, users do not need to frequently maintain, which improves the overall user experience.

[0053] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
