Technical Field
[0001] This utility model relates to the field of vacuum cleaner roller brush technology, specifically a commercial vacuum cleaner roller brush. Background Technology
[0002] Vacuum cleaners are essential cleaning tools in our daily lives, and one of their most important components is the roller brush. The roller brush is one of the core components of a vacuum cleaner; its function is to use the rotating brush to suck up dust, hair, and other debris from the floor, thus cleaning the floor. The roller brush's main function is to clean dust, hair, and other debris from the floor. When the vacuum cleaner is working, the rotating brush grabs the debris and brings it into the vacuum cleaner, achieving a clean floor. Household cleaning requires cleaning various types of floors, including tiles, hardwood floors, and carpets, and different cleaning scenarios require different brush heads.
[0003] Existing vacuum cleaner roller brushes typically need to be connected to the external vacuum cleaner via two side rollers. However, the diameter of the rollers is usually smaller than the diameter of the brush. During use, foreign objects such as hair easily get tangled on the side rollers, making them difficult to clean and affecting the use of the device. In addition, vacuum cleaner roller brushes have strong water absorption, and when disassembled for cleaning, it is difficult to scrape off the water absorbed by the roller brush. This results in a long drying time and water dripping during the drying process, affecting the user experience. Summary of the Invention
[0004] Based on this, the purpose of this utility model is to provide a commercial vacuum cleaner roller brush to solve the technical problems of existing vacuum cleaner roller brushes, such as the easy entanglement of hair and other foreign objects on both sides of the roller, making cleaning difficult, as well as the strong water absorption of the roller brush, making it difficult to dry quickly after washing and causing water droplets to fall during drying.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a commercial vacuum cleaner roller brush, comprising a main body and functional components, wherein the functional components include an anti-fouling mechanism and a wiping mechanism, wherein the wiping mechanism includes a wiping ring, the surface of which is provided with external threads, one end of which is provided with a knob, the outer surface of which is provided with a protrusion, and the inner wall of which is provided with a raised ring.
[0006] By adopting the above technical solution, the knob makes the installation and removal of the wiper ring more convenient and quick.
[0007] Furthermore, the bumps are arranged in a circular array with equal and uniform spacing.
[0008] By adopting the above technical solution, the friction and resistance generated between the protrusion and the contact surface when the user rotates the knob prevents the knob from slipping when wet.
[0009] Furthermore, four wiper rings are provided, and the four wiper rings are arranged in a linear array at equal intervals.
[0010] By adopting the above technical solution, the multiple squeegee rings can more effectively remove water and dirt from the surface of the roller brush, improving cleaning efficiency.
[0011] Furthermore, a fixing ring is provided at one end of the main body, and two fixing rings are symmetrically arranged along the central axis of the main body.
[0012] By adopting the above technical solution, the fixing ring provides an additional support point for the roller brush, which enhances the stability of the roller brush when it rotates at high speed or is subjected to external force, and reduces vibration and shaking.
[0013] Furthermore, the anti-fouling mechanism includes a first retaining ring and a second retaining ring. A snap-fit groove is provided on one side of the first retaining ring, and the inner wall of the snap-fit groove is provided with an internal thread.
[0014] By adopting the above technical solution, the snap-fit groove allows the wiper mechanism to be easily installed on the first retaining ring, improving the ease of installation.
[0015] Furthermore, the inner walls of the first and second retaining rings are fixedly connected to the fixed ring, and the diameters of the first and second retaining rings are larger than the diameter of the main body.
[0016] By adopting the above technical solution, the tight connection between the retaining ring and the fixed ring reduces the chance of debris entering the inside of the roller, effectively blocking hair, dust and other dirt, and keeping the roller brush clean and running smoothly.
[0017] Furthermore, the snap-fit groove is adapted to the wiper ring.
[0018] By adopting the above technical solution, the fit between the snap-fit groove and the wiper ring ensures the stability of the wiper ring when it is in a fixed position.
[0019] In summary, the present invention has the following main advantages:
[0020] This invention incorporates a squeegee mechanism. After cleaning the roller brush, the surface of the roller brush absorbs a large amount of water, making it difficult to dry naturally and quickly. This allows users to loosen the squeegee ring from the locking groove by turning a knob, and then pull the squeegee ring up and down to squeeze out the water from the roller brush surface. The addition of the convex ring further enhances the squeegee ring's water-squeegee ability, enabling the roller brush to dry more quickly. This not only shortens the drying time of the roller brush but also avoids the problem of water dripping during the drying process, thus improving the user experience.
[0021] This invention features an anti-fouling mechanism with two retaining rings that effectively prevent hair, dust, or other debris from entering the roller. This reduces the amount of debris entering the roller, keeps the roller brush clean and runs smoothly, thereby extending the service life of the roller brush and improving the overall performance of the vacuum cleaner. It also provides space for fixing and storing the squeegee ring. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example
[0028] A commercial vacuum cleaner roller brush, such as Figures 1-4 As shown, it includes a main body 1 and a functional component 2. The functional component 2 includes an anti-fouling mechanism 3 and a wiping mechanism 4. The wiping mechanism 4 includes a wiping ring 401. The surface of the wiping ring 401 is provided with an external thread 402. One end of the wiping ring 401 is provided with a knob 403. The outer surface of the knob 403 is provided with a protrusion 404. The inner wall of the wiping ring 401 is provided with a protruding ring 405. The knob 403 makes the installation and removal of the wiping ring 401 more convenient and quick. The wiping ring 401 enables the roller brush to more effectively remove residual water and dirt from the surface during the cleaning process, thereby improving cleaning efficiency.
[0029] See Figure 4The bumps 404 are arranged in a circular array at equal intervals. When the user rotates the knob 403, the friction and resistance generated between the bumps 404 and the contact surface prevent the knob 403 from slipping when wet. The uniform distribution of the bumps 404 makes the knob 403 more evenly stressed during rotation.
[0030] See Figure 4 There are four wiper rings 401 arranged in a linear array at equal intervals. The arrangement of multiple wiper rings 401 can more effectively remove water and dirt from the surface of the roller brush, improve cleaning efficiency, and the evenly spaced arrangement ensures that each wiper ring 401 can contact the same area of the roller brush surface, achieving uniform wiping and avoiding local water or dirt residue.
[0031] See Figure 3 One end of the main body 1 is provided with a fixing ring 5. There are two fixing rings 5 symmetrically arranged along the central axis of the main body 1. The fixing rings 5 provide additional support points for the roller brush, which enhances the stability of the roller brush when rotating at high speed or subjected to external force, and reduces vibration and shaking. The symmetrical arrangement of the two fixing rings 5 makes the roller brush more evenly stressed, avoiding deformation or damage caused by excessive force on one side, and extending the service life of the roller brush. Example
[0032] See Figure 3 The anti-fouling mechanism 3 includes a first retaining ring 301 and a second retaining ring 304. A snap-fit groove 302 is provided on one side of the first retaining ring 301. An internal thread 303 is provided on the inner wall of the snap-fit groove 302. The snap-fit groove 302 allows the wiper mechanism 4 to be easily installed on the first retaining ring 301, improving the ease of installation. The cooperation between the internal thread 303 and the external thread 402 allows the wiper mechanism 4 to be firmly installed in the snap-fit groove 302, making it less likely to loosen or fall off.
[0033] See Figure 3 The inner walls of the first retaining ring 301 and the second retaining ring 304 are fixedly connected to the fixed ring 5. The diameters of the first retaining ring 301 and the second retaining ring 304 are larger than the diameter of the main body 1. The tight connection between the retaining ring and the fixed ring 5 reduces the chance of debris entering the roller, effectively blocking hair, dust and other dirt, keeping the roller brush clean and running smoothly. The fixed connection between the fixed ring 5 and the retaining ring enhances the overall structural stability of the roller brush, making the roller brush less prone to deformation or damage when rotating at high speed or subjected to external impact.
[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4The snap-fit groove 302 is adapted to the wiper ring 401. The adaptation between the snap-fit groove 302 and the wiper ring 401 ensures the stability of the wiper ring when it is in a fixed position. The snap-fit groove 302 ensures that the wiper ring 401 will not easily loosen or fall off due to external force, thus ensuring the normal operation of the roller brush.
[0035] The implementation principle of this utility model is as follows: First, the wiper ring 401 is fixed in the snap-fit groove 302 by the external thread 402. The first retaining ring 301 and the second retaining ring 304 at both ends of the main body 1 prevent hair and other objects from entering the rollers on both sides and avoiding entanglement. After the roller brush is cleaned, the knob 403 can be turned to make the wiper ring 401 disengage from the snap-fit groove 302. Then, the wiper ring 401 is pulled up and down, and the wiper ring 401 squeezes out the water from the dust-collecting layer on the surface of the roller brush. At the same time, the convex ring 405 increases the wiping ability of the wiper ring 401.
