Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a roller brush structure for a floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously vacuuming up wastewater and removing it from the site. It combines cleaning and drying functions and has advantages such as being environmentally friendly, energy-saving, and highly efficient. It is widely used in shopping malls, supermarkets, stations, factories, airports, and other places. The floor scrubber uses a power component to drive the roller brush to rotate, which, together with clean water and detergent, cleans the floor. Then, a vacuum motor and squeegee collect the wastewater and dust into the wastewater tank, achieving rapid cleaning and drying of the floor.

[0003] Traditional floor scrubbers mainly consist of a motor, rollers, brush assembly, vacuum motor, squeegee, and wastewater tank. Their working principle is as follows: The motor drives the rollers to rotate via gears or belts, causing the brush assembly to come into contact with the floor and rub against it. During rotation, the brush assembly generates physical friction with the floor, removing stains and dust. The stiff bristles initially remove stubborn stains, the soft bristles absorb wastewater and dust, and the microfiber bristles perform deep cleaning, achieving a comprehensive cleaning effect. The vacuum motor generates a high-speed airflow, creating a vacuum in the wastewater tank. The squeegee then collects the wastewater and dust back into the tank through a suction pipe, keeping the floor dry.

[0004] However, the roller brush structure of traditional floor scrubbers has some shortcomings in use. The bristles of the roller brushes on traditional floor scrubbers are made of a single material, and the roller brushes need to be replaced frequently to clean different areas, which is difficult to adapt to different cleaning needs and is very inconvenient.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-6 The present invention provides the following two preferred embodiments:

[0023] Example 1: A roller brush structure for a floor scrubber includes a mounting shell 1. Mounting holes 4 are provided on both sides of the mounting shell 1. The mounting holes 4 are used to accommodate a movable shaft 5, through which a retaining ring 6 is threadedly connected via an external thread 7 on the outer wall of the movable shaft 5, thus mounting and fixing the roller brush assembly 2. The movable shaft 5 is inserted into the inner wall of the mounting holes 4. A movable block 8 is fixedly connected to the end of the movable shaft 5 away from the mounting holes 4. A connecting shaft 3 is slidably connected to the outer wall of the movable block 8. The roller brush assembly 2 is rotatably connected to the end of the connecting shaft 3 away from the movable block 8. An external thread 7 is provided on the outer surface of the end of the movable shaft 5 away from the movable block 8. The thread direction of the external thread 7 is opposite to the rotation direction of the roller brush 22 to prevent the retaining ring 6 from loosening under vibration. The movable shaft 5 is fixedly connected via the external thread 7. The threaded connection 7 has a fixing ring 6, and multiple rotating protrusions are fixedly connected to the outer surface of the fixing ring 6. The rotating protrusions are arranged in a ring array. This design allows the operator to rotate the fixing ring 6 by holding the rotating protrusions, thereby fixing and disassembling the movable shaft 5. The inner wall of the connecting shaft 3 has an installation groove 9, and a return spring 10 is inserted into the inner wall of the installation groove 9. The movable block 8 has an insertion groove on the side near the installation groove 9. The end of the return spring 10 away from the installation groove 9 is inserted into the insertion groove. The function of the return spring 10 is to store elastic potential energy when the movable shaft 5 is compressed and retracted. When the movable shaft 5 is released, the return spring 10 returns to its original shape and pushes the movable shaft 5 out of the inner cavity of the connecting shaft 3, so that the movable shaft 5 can pass through the installation hole 4 for installation and fixing.

[0024] In actual use, first press the movable shaft 5 to retract it into the inner cavity of the connecting shaft 3. During the retraction of the movable shaft 5, the movable block 8 slides on the inner wall of the connecting shaft 3 and squeezes the return spring 10. At this time, place the roller brush assembly 2 into the mounting housing 1. Align the end of the movable shaft 5 with the external thread 7 with the mounting hole 4 on the outer wall of the mounting housing 1. Release the press of the movable shaft 5. The return spring 10 returns to its original position and pushes the movable block 8 to slide on the inner wall of the connecting shaft 3. Push the movable shaft 5 out of the inner cavity of the connecting shaft 3 and through the mounting hole 4. Then, thread the fixing ring 6 through the external thread 7 on the outer wall of the movable shaft 5. Hold the rotating protrusion and tighten the fixing ring 6 to complete the installation of the roller brush assembly 2.

[0025] Example 2: The roller brush assembly 2 includes a mounting roller 21 rotatably connected to the end of the connecting shaft 3 away from the movable block 8. The outer wall of the mounting roller 21 has multiple T-shaped grooves 27 arranged in a circular array. Multiple T-shaped sliders 26 are slidably connected to the inner wall of the T-shaped grooves 27, arranged in a linear array. Three roller brushes 22 are fixedly connected to the side of each T-shaped slider 26 away from the T-shaped grooves 27. The design of the T-shaped sliders 26 and T-shaped grooves 27 allows for quick replacement of the roller brushes 22, enabling users to choose the appropriate brush for different cleaning needs. A roller brush 22 with bristles of different materials is required; a threaded hole 23 is opened on the outer wall of the mounting roller 21, and a cover plate 24 is inserted into the outer wall of the mounting roller 21. Multiple through holes are opened on the outer surface of the cover plate 24, and hexagon socket bolts 25 are inserted into the inner wall of the through holes. The outer wall of the hexagon socket bolts 25 is threadedly connected to the inner wall of the threaded hole 23. The hexagon socket bolts 25 that fix the cover plate 24 are removed one by one, and then the cover plate 24 is removed to facilitate the replacement of the roller brush 22. After the cover plate 24 is fixed by the hexagon socket bolts 25, the roller brush 22 can be limited and fixed to prevent the roller brush 22 from falling off during use.

[0026] In actual use, when it is necessary to replace the roller brush 22 or combine roller brushes 22 with different bristle materials, remove the hexagon socket bolts 25 of the fixing cover plate 24 one by one, and then remove the cover plate 24. At this time, the roller brush 22 can be pulled and slid through the T-shaped slider 26 on the roller brush 22 in the T-shaped groove 27 on the mounting roller 21. Align the T-shaped sliders 26 on the three new roller brushes 22 or roller brushes with different bristle materials with the T-shaped groove 27 on the mounting roller 21 and push them in. Then fix the cover plate 24 with the hexagon socket bolts 25.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
