Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a cleaning strip, a roller brush, a vacuum cleaner, and a mold. Background Technology

[0002] To meet consumers' needs for different uses on carpets and floors, the cleaning elements of existing vacuum cleaner roller brushes mainly include stiff bristle tufting, soft bristle tufting, velour cloth, and leather strips.

[0003] Currently, single-strip roller brushes can only be used on floors. This is because the large contact area of ​​the single-strip brush limits its elasticity, making it unable to remove hair and dust from carpet seams when used for carpet cleaning. It also fails to achieve a multi-functional cleaning effect. Therefore, when cleaning carpets, it is necessary to switch to a bristle roller brush.

[0004] Existing bristle roller brushes can only be used on carpets; otherwise, they will damage the smoothness of floors. Therefore, in home or commercial office settings with carpets and floors, vacuum cleaners need to be purchased or purchased separately with roller brushes of different materials such as hard bristles, soft bristles, leather strips, and velvet for easy replacement. This is inconvenient, prone to being lost, and also increases costs.

[0005] Therefore, to date, no vacuum cleaner floor brush has achieved a practical breakthrough by using a single roller brush for cleaning both floors and carpets.

[0006] While some roller brushes currently incorporate at least two cleaning elements, such as strips and bristles, to achieve effective cleaning on different surfaces simultaneously, the height of the strips protruding from the brush surface is usually reduced. This prevents them from directly cleaning carpet fibers or penetrating the carpet's interior. The strips only clean a wide surface area and cannot effectively reach the carpet's interior. Furthermore, the strips can easily damage and deform the carpet, affecting its shape after cleaning. In short, the integrated strip structure in existing vacuum cleaners is ineffective for cleaning carpets.

[0007] Although there are now structures with a row of teeth on the outer edge of the leather strip, its main body is still a relatively wide leather strip shape. Therefore, although it can be used to clean the surface of the carpet, it cannot reach into the inside of the carpet for cleaning.

[0008] Existing roller brushes require multiple cleaning elements to be set on a single roller brush in order to achieve the effect of cleaning different surfaces simultaneously without getting hair tangled. Utility Model Content

[0009] To solve the above-mentioned technical problems, this utility model provides a cleaning strip for a vacuum cleaner's roller brush body. The cleaning strip includes an installation area and is a flexible cleaning strip. The cleaning strip also includes at least one cleaning protrusion connected to the installation area. A notch is provided between any two cleaning protrusions. The width of the notch at the end away from the installation area is greater than 0 mm, and the width of the notch at the end near the installation area is ≥0 mm. When the cleaning strip is placed on the roller brush body, the notch is formed on the outer surface of the brush body.

[0010] The cleaning strip of this utility model has the following beneficial effects:

[0011] ①This application changes the existing one-piece structural design of cleaning strips used in vacuum cleaners and breaks the existing cleaning strips that can only be used for cleaning hard floors. The roller brush using the cleaning strip of this application can also be used for cleaning carpets and the like. Its cleaning protrusions can extend into the carpet to thoroughly remove hair or dirt, and are not limited to cleaning the carpet surface. At the same time, notches are set between the cleaning protrusions, and the cleaning protrusions have a certain degree of flexibility, so as to avoid damaging or deforming the carpet during the cleaning process.

[0012] ② Using a roller brush equipped with or fitted with the cleaning strip of this application, since the cleaning protrusions have a certain degree of flexibility and there are gaps between each cleaning protrusion, hair is not easily caught or wrapped around the cleaning strip.

[0013] ③ Because the cleaning strip of this application is made of a flexible material, it will not damage the carpet. At the same time, the roller brush with the cleaning strip installed can effectively remove dirt from hard surfaces. Therefore, a single roller brush can be used to clean various surfaces of different hardness and softness, eliminating the need for users to change roller brushes for different floor types, greatly simplifying user experience. It also eliminates the need to set multiple different cleaning elements on the surface of a single roller brush, simplifying the processing cost and manufacturing process of the roller brush body.

[0014] Furthermore, the cleaning strip has a Shore A hardness of 30-85 degrees, and the material of the cleaning strip is selected from at least one of plastic, silicone, or soft rubber. Therefore, within this hardness range, the cleaning strip can ensure that it has both elasticity and strength, effectively removing hair when inserted into the carpet for cleaning, without putting excessive pressure on the carpet and causing it to deform.

[0015] Furthermore, the distance between any two of the cleaning protrusions near the mounting area shall not exceed 30 mm.

[0016] This utility model also provides a roller brush body, wherein at least one mounting groove for mounting a cleaning strip is provided on the outer surface of the roller brush body. The cleaning strip includes a mounting area disposed in the mounting groove. The cleaning strip is a flexible cleaning strip and also includes a plurality of cleaning protrusions connected to the mounting area. A notch is provided between any two cleaning protrusions. The width of the notch at the end away from the mounting area is greater than 0 mm, and the width of the notch at the end near the mounting area is ≥ 0 mm. When the cleaning strip is mounted on the roller brush body, the notch is formed on the outer surface of the brush body. The roller brush of this invention includes a cleaning strip with cleaning protrusions that can extend into the carpet to effectively remove hair and other debris. By creating notches between the cleaning protrusions, and by ensuring the protrusions have flexible deformation capabilities, hair is prevented from getting caught between adjacent protrusions or from becoming entangled on the roller brush. Because the roller brush uses flexible cleaning protrusions, it can also effectively clean hard surfaces such as floors. Therefore, a single type of roller brush can be used to clean various surfaces.

[0017] Furthermore, the cleaning protrusion is columnar, and the width of the notch at the end near the mounting area is >0 mm.

[0018] Furthermore, the distance between any two of the cleaning protrusions near the mounting area shall not exceed 30 mm.

[0019] Furthermore, the width of the cleaning protrusion is 1mm-20mm.

[0020] Furthermore, the roller brush body is also provided with at least one of a leather strip, a soft brush, and a hard brush.

[0021] Furthermore, the roller brush body is also provided with at least one of a leather strip, a soft brush, and a hard brush.

[0022] This utility model also provides a roller brush body, including a main body and a brush body part located outside the main body. At least a portion of the outer surface of the brush body part is provided with a plurality of cleaning protrusions of the aforementioned cleaning strip. A notch is also provided between any two adjacent cleaning protrusions. The width of the end of the notch away from the brush body part is greater than 0 mm, and the width of the end of the notch near the brush body part is ≥0 mm. The notch is formed on the outer surface of the brush body part, and the cleaning protrusions are integrally formed on the outer surface of the brush body part. When cleaning a carpet, the cleaning protrusions can extend into the interior of the carpet.

[0023] This utility model also provides a mold for producing the aforementioned brush body.

[0024] This utility model also provides a vacuum cleaner, which includes the aforementioned cleaning strip or the aforementioned roller brush. Attached Figure Description

[0040] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0041] Example 1:

[0042] See appendix Figure 1 and 2 As shown, this embodiment is a cleaning strip 1, which is a flexible cleaning strip made of a flexible material. Here, "flexible" means that the cleaning strip 1 has a certain degree of hardness, but still retains a certain degree of deformation capability and elastic recovery force. For example, it can be made of at least one of plastic, silicone, or soft rubber. Examples include polyurethane elastomer (PU), thermoplastic elastomer (TPE), polyvinyl chloride (PVC), etc.

[0043] The cleaning strip 1 in this embodiment includes an installation area 12 and at least one cleaning protrusion 11 connected to the installation area 12. A notch 13 is provided between any two cleaning protrusions 11. The width of the end of the notch 13 away from the installation area 12 is greater than 0 mm, and the width of the end of the notch 13 near the installation area 12 is ≥0 mm. That is, the root of the cleaning protrusion 11 (the end near the installation area 12) may not have a gap. When the cleaning strip 1 is set on the roller brush body, the notch is formed on the outer surface of the brush body portion 22. In other words, the cleaning protrusion 11 has a relatively long length along the width direction of the cleaning strip 1, thereby ensuring that when the cleaning strip 1 is installed on the roller brush body, the length of the cleaning strip 1 extending into the carpet fibers is relatively large, thereby achieving effective cleaning of the carpet fibers. Note that the cleaning protrusion 11 in this embodiment has a relatively large height protruding from the surface of the roller brush body, and is not a serrated shape provided only within the limited width of the outer edge of the cleaning strip 1. Therefore, the cleaning protrusion 11 of this application can fully penetrate into the carpet to effectively clean the hair inside.

[0044] Therefore, without the need for additional cleaning components, the cleaning effect on floors and carpets can be achieved simply by using the roller brush equipped with the cleaning strip 1 of this application. When cleaning carpets using the roller brush equipped with the cleaning strip 1 of this embodiment, the cleaning protrusions 11 can extend into the interior of the carpet and clean hair and other debris within the carpet. Since a notch 13 is provided between any two cleaning protrusions 11 of the cleaning strip 1 of this application, and the cleaning protrusions 11 are flexible, hair is less likely to be caught between adjacent cleaning protrusions 11, nor is it likely to become tangled on the cleaning strip 1.

[0045] Using the floor brush equipped with the cleaning strip 1 of this embodiment, when cleaning the carpet, the cleaning protrusions 11 have a certain degree of elasticity, allowing for patting and scraping on the carpet. Furthermore, the elasticity of the cleaning strip 1 provides better adhesion between the brush and the carpet fibers, resulting in greater friction between the brush and the carpet. The cleaning strip 1 allows the carpet fibers to exert a strong traction force on the brush, propelling it forward automatically. Even on long-pile carpets, it can easily remove dust from the carpet crevices without requiring manual pushing, allowing it to be sucked into the dust cup by the vacuum cleaner. The notches 13 between the cleaning protrusions 11 ensure that the cleaning strip 1 does not completely flatten the carpet fibers, preventing negative impacts such as sagging on the carpet's appearance after cleaning.

[0046] In some embodiments, the hardness of the cleaning strip 1 is Shore A 30-85. If the hardness of the cleaning strip 1 is too low, it will not be effective at removing hair; while if the hardness of the cleaning strip 1 is too high, it will easily damage the carpet, and if the gap between adjacent cleaning protrusions 11 is too small, hair will still easily get tangled on the surface of the cleaning strip 1. Therefore, this application controls the hardness of the cleaning strip 1 to Shore A 30-85, so that the cleaning strip 1 has both suitable softness and strength. In addition, because the cleaning strip 1 has a certain degree of softness and elasticity, it can adapt to uneven ground and can effectively clean hair on different surfaces such as floors and carpets without causing hair to be caught or tangled in the cleaning strip 1.

[0047] In some embodiments, the outer radial direction of the cleaning protrusion 11 gradually decreases away from the mounting area 12. For example, the cleaning protrusion 11 can be at least one of toothed, conical, or truncated cone (e.g., it can be conical or pyramidal).

[0048] In some embodiments, the cleaning strip 1 is sheet-shaped, and is obtained by punching or cutting the edges of the sheet-shaped strip to create the notch 13. The cleaning protrusion 11 is the area at the edge of the cleaning strip 1 that was not punched or cut off. See Appendix. Figure 1 and 2 As shown, the cleaning protrusion 11 is a structure with multiple teeth set at the edge of the rubber strip. Therefore, only rubber strips, which are currently widely used in the vacuum cleaner industry, need to be used, and their edges can be simply punched or cut to form some V-shaped grooves or arc-shaped grooves, etc., to obtain the cleaning strip 1 of this application. This makes the processing cost of the cleaning strip 1 extremely low and the processing technology simple. The "arc-shaped groove" punched here refers to the shape of the left and right side walls of the groove being arc-shaped (e.g., Figure 3(As shown). The bottom of the punched groove can be V-shaped or beveled. The case where the bottom of the groove is V-shaped is when the distance between the ends of each cleaning protrusion 11 closest to the mounting area 12 is 0.

[0049] This application breaks with industry practice by creating a number of cleaning protrusions 11 on a leather strip that cannot be inserted into the carpet to directly clean hair. This allows the cleaning protrusions 11 to be inserted directly into the carpet for cleaning, thus utilizing the cleaning protrusions 11 structure of the leather strip itself to achieve a cleaning effect.

[0050] In other possible implementations, the cleaning protrusion 11 is columnar (e.g., it can be cylindrical, cuboid, cube, or prism-shaped), and the width of the end of the notch 13 near the mounting area 12 is greater than 0 mm. Since the cleaning protrusion 11 is columnar, the width of the end of the notch 13 near the mounting area 12 needs to be set to be greater than 0 mm, thereby ensuring sufficient gaps between the individual cleaning protrusions 11.

[0051] In some embodiments, the distance between the ends of any two cleaning protrusions 11 closest to the mounting area 12 does not exceed 30 mm. Otherwise, such a large distance will prevent the effective cleaning of the floor or carpet surface.

[0052] In some embodiments, the width of the cleaning protrusion 11 is 1mm-20mm. Here, "width of the cleaning protrusion 11" refers to the length of the cleaning protrusion 11 along the length of the cleaning strip 1 (for cases where the cleaning protrusion 11 is toothed) or its outer diameter (for cases where the cleaning protrusion 11 is conical, truncated conical, or cylindrical). The width of the cleaning protrusion 11 can be adjusted according to the length of the roller brush. For example, in small roller brushes, since the length of the roller brush is generally 10-30cm, the width of the cleaning protrusion 11 can be set to only 1mm, 3mm, or 5mm, etc. In large industrial vacuum cleaners, since the length of the roller brush can reach 2m-3m, the width of the cleaning protrusion 11 can also be set to 20mm. The percentage of the width of each cleaning protrusion 11 along the length of the roller brush body is extremely low, for example, it can be 0.05%, 0.1%, 0.2%, 0.5%, 1%, etc. This is to create a structure on the cleaning strip 1 with several cleaning protrusions 11 that can reach into the interior of the carpet for cleaning.

[0053] Example 2:

[0054] This embodiment describes a roller brush body 2, which can be a cleaning brush for a vacuum cleaner floor brush, a cleaning brush for a sweeper, or a cleaning brush for a sweeper robot. See attached document. Figure 4 and Figure 5As shown, it includes a body portion 21, and at least one mounting groove 211 for mounting a cleaning strip 1 is provided on the outer surface of the body portion 21. The mounting area of ​​the cleaning strip 1 can be snapped into the mounting groove 211. A notch 13 is also provided between any two adjacent cleaning protrusions 11 of the cleaning strip 1. The width of the end of the notch 13 away from the brush body portion 22 is greater than 0 mm, and the width of the end of the notch 13 near the brush body portion 22 is ≥0 mm. The roller brush body 2 of this embodiment breaks through the limitations of the existing roller brush body 2. The cleaning protrusions 11 can not only clean dirt on the floor surface, but also reach into the carpet to effectively remove hair and other debris. Therefore, the roller brush body 2 of this embodiment can achieve cleaning effects on both hard floors and carpets using only one cleaning element.

[0055] The cleaning protrusions 11 on the outer surface of the roller brush body 2 are arranged in at least one of the following ways: arranged along the axial direction of the roller brush body 2. Figure 5 ), arranged spirally along the surface of the roller brush body 2 ( Figure 4 ), staggered on the surface of the roller brush body 2 ( Figure 10 The cleaning protrusions 11 are arranged in a V-shape along the surface of the roller brush body 2. Each cleaning protrusion 11 can be arranged continuously or intermittently. Figure 10 The installation groove 211 can be a groove structure of various shapes, such as inclined groove, straight groove, V-shaped groove, human-shaped groove, spiral groove, etc.

[0056] The number of cleaning protrusions 11 provided on the surface of the roller brush body 2 may include at least one row, and the cleaning protrusions 11 of adjacent rows may be staggered as needed. For example, the cleaning protrusions 11 of the next row are directly opposite the gap between the adjacent cleaning protrusions 11 of the previous row. Therefore, the cleaning protrusions 11 of each row can play a better role in cooperation and have a better cleaning effect on dirt.

[0057] See also some possible implementations. Figure 6 Multiple mounting grooves 211 can be provided on the outer surface of the main body 21, and they are arranged in groups of three. "A group" means that the distance between each group of mounting grooves 211 is less than the distance between two adjacent groups of mounting grooves 211. Following the order in which the roller brush contacts the ground as it rotates, the cleaning elements provided in each group of mounting grooves 211 are, in sequence, a cleaning strip 1, a leather strip 4, and a brush 5. Therefore, it can effectively clean carpet surfaces, carpet interiors, and hard floor surfaces.

[0058] In some possible implementations, the body portion 21 and the brush portion 22 are two different components. See also Figure 7-10As shown, the brush body 22 may include a hollow cylindrical brush body 221, with each cleaning protrusion 11 integrally formed on the outer surface of the brush body 221. Correspondingly, the roller brush 2 has a body portion 21 located inside the brush body 221. Therefore, a brush body 22 with several cleaning protrusions 11 can be first processed using processes such as extrusion molding, blow molding, foam molding, or casting. Then, the brush body 22 is fitted onto the outer surface of the body portion 21 of the roller brush 2. In other possible embodiments, the brush body 22 can also be directly injection molded or coated onto the outer surface of the body portion 21.

[0059] In some embodiments, the body portion 21 and the brush body portion 22 can also be integrally molded. For example, various soft materials such as plastics, silicone, or soft rubber with a Shore A hardness range of 30 to 85 degrees can be used to directly mold comb-shaped, serrated, or columnar shapes on the outer surface of the brush body portion through injection molding, or extrusion molding, blow molding, foam molding, or casting molding to directly produce an integral structure of a roller brush with several cleaning protrusions 11.

[0062] Example 4:

[0063] This embodiment is a mold 3 used to produce the brush body 22 of Embodiment 2. In some embodiments, see the appendix. Figure 11 As shown, the mold 3 includes a first cavity 31 corresponding to the body portion 21 of the roller brush 2 and a second cavity 32 corresponding to the brush portion 22, and the first cavity 31 and the second cavity 32 are interconnected. The mold 3 in this embodiment can be an injection mold 3 or a blow mold 3.
