Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a mounting assembly for a roller brush. Background Technology

[0002] A roller brush is a rotating brush widely used in cleaning equipment, primarily in robotic vacuum cleaners, floor scrubbers, and industrial cleaning equipment. Its core function is to remove dust, stains, or debris from the surface of a floor or object through rotational friction. Traditional roller brush installations often use bolt fixing or simple snap-fit ​​structures, which have the following problems:

[0003] 1) Lack of anti-tangling design: During use, the roller brush is prone to getting tangled with hair, thread, or other debris. This not only affects the cleaning effect but may also cause the roller brush to jam or be damaged, shortening the service life of the equipment. The lack of an effective anti-tangling design increases the difficulty of maintenance, requiring users to clean the roller brush frequently and reducing the efficiency of use.

[0004] 2) Limited compatibility: The installation design of existing equipment is usually only applicable to specific models or brands of roller brushes, and cannot be adapted to various specifications of roller brushes. This design limits the range of choices for users and increases the cost of use. In addition, limited compatibility may also complicate the installation process and affect the user experience.

[0005] Therefore, we propose a mounting component for roller brushes to address the problems mentioned above. Utility Model Content

The fixed end cap assembly 4 and the drive end top cap 5 are respectively installed at both ends of the roller brush cylinder 1, and the two ends of the roller brush cylinder 1 are sealed to prevent internal parts from being exposed, reduce the entanglement of hair, cables, etc. by the protruding parts of the installation structure, reduce the damage of the entangled material to the roller brush, extend the service life of the equipment, reduce the difficulty of maintenance, and improve the efficiency of use.

[0029] Example 2, as Figure 2 - Figure 3 As shown, this utility model provides an installation assembly for a roller brush: a drive shaft 6 is installed inside the roller brush cylinder 1, and both ends of the drive shaft 6 pass through the bottom end of the bearing bush 3. A stabilizing assembly 7 located inside the bearing bush 3 is fitted at one end of the drive shaft 6 near the fixed end cover assembly 4.

[0032] The effect achieved by the entire embodiment 3 is as follows: one end of the drive shaft 6 passes through the drive end top cover 5, and its end is connected to the external power source through the drive engagement structure 8. The third engagement protrusion 801 of the drive engagement structure 8 is embedded in the groove inside the drive shaft 6 to realize torque transmission. The drive engagement structure 8 can be replaced separately to adapt to different brands of drive interfaces, which enhances the compatibility and flexibility of the components.

[0033] The working principle of the entire installation component is as follows:

[0034] Roller brush installation and fixing: Insert both ends of the roller brush cylinder 1 into the bearing bushing 3 respectively. The bearing bushing 3 is designed with three different inner diameter specifications. By replacing the bushing body 301 with different inner diameter specifications, roller brush cylinders with different diameters can be adapted. Insert the first fitting protrusion 402 of the fixing end cover body 401 into the first slot 302 of the bushing body 301 to form a radial lock. The fixing shaft 405 passes through the fixing end cover body 401 and connects to the bearing 406. Axial locking is achieved by the buckle 404 on the buckle base 403. The spring 702 in the stabilizing assembly 7 compresses the first friction plate 701 and the second friction plate 703 to generate friction force to suppress loosening caused by vibration.

[0035] Power transmission and drive: One end of the drive shaft 6 passes through the drive end top cover 5, and its end is connected to an external power source through the drive engagement structure 8. The third engagement protrusion 801 of the drive engagement structure 8 is embedded in the groove inside the drive shaft 6 to realize torque transmission; the second engagement protrusion 502 of the drive end top cover body 501 cooperates with the first slot 302 of the bearing bushing 3 to ensure coaxial rotation.

[0036] Anti-tangling and maintenance optimization: The bristles 2 reduce linear tangling. With the continuous rotation of the roller brush body 1, hair, cables, etc. are guided to both ends. The fixed end cap assembly 4 and the drive end top cover 5 are respectively installed at both ends of the roller brush body 1 and seal both ends of the roller brush body 1 to prevent internal parts from being exposed and reduce the tangling of hair, cables, etc. by the protruding parts of the installation structure. The fixed shaft 405 is released by the buckle 404, and the roller brush body 1 can be disassembled within five seconds to clean up the tangled material. The drive engagement structure 8 can be replaced separately to adapt to different brands of drive interfaces. The bearing bushing 3 is made of POM material, which is wear-resistant and supports lubrication-free operation, reducing the maintenance frequency.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
