[0039] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0040] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0041] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0042] like Figures 1 to 5 As shown, a roller brush 100 is provided according to a first aspect of the present application, comprising: a roller body 110 and a plurality of cleaning elements 120, wherein the cleaning elements 120 are disposed on the roller body 110, and the plurality of cleaning elements 120 are arranged at intervals along the circumference of the roller body 110; wherein at least one of the plurality of cleaning elements 120 is an antistatic cleaning element 121, and the surface resistivity of the bristles of the antistatic cleaning element 121 is less than 10. 12 Ω / sq.

[0043] The roller brush 100 provided in this embodiment includes a roller body 110 and multiple cleaning components 120. During operation, the roller body 110 rotates, causing the cleaning components 120 to contact the surface to be cleaned. The cleaning components 120 can pat, move, or even pick up hair and dust from the carpet, allowing the cleaning equipment to collect the hair and dust. Furthermore, at least one of the cleaning components 120 is an antistatic cleaning component 121, with a surface resistivity of less than 10. 12 The Ω / sq value gives the antistatic cleaning component 121 strong conductivity. The antistatic cleaning component 121 itself does not easily store charge, but conducts the charge on the surface to be cleaned to the cleaning equipment. Based on this, the total static electricity on the surface to be cleaned can be reduced, which can reduce the adsorption of hair and fine dust on the surface to be cleaned, thereby improving the cleaning effect.

[0044] Understandably, in order to improve the static electricity suppression effect of the roller brush 100, the antistatic cleaning component 121 can be two or more.

[0045] It is understood that the roller brush 100 provided in this application embodiment may not change the structure of the existing roller body 110, or in other words, may not increase the number of cleaning components 120 on the roller body 110. Instead, the traditional cleaning components 120 on the existing roller brush 100 may be replaced with antistatic cleaning components 121. Of course, antistatic cleaning components 121 may also be added to the traditional roller body 110. Therefore, this application does not limit the specific number of cleaning components 120, as long as it can achieve the effect of reducing static electricity on the surface to be cleaned.

[0046] According to the embodiments of this application, the roller brush 100 reduces the amount of charge generated on the carpet during the cleaning process and increases the number of times the hair is patted and moved, especially improving the problem of hair being difficult to clean in low humidity (e.g., humidity ≤40%) environments.

[0047] In some examples, to further improve the antistatic performance of the antistatic cleaning component 121, the surface resistivity of the antistatic cleaning component 121 can be 10⁻⁶. -8 Ω / sq up to 10 12 Ω / sq, for example, antistatic cleaning part 121 can be made of metal material with a surface resistivity of 1.6×10 Ω / sq. -8 Ω / sq, 1.7×10 -8 Ω / sq, 2.4×10 -8 Ω / sq, 2.8×10 -8 Ω / sq, 9.7×10 -8 Ω / sq, 1.1×10 -7 Ω / sq, etc., the antistatic cleaning part 121 can also be made of carbon fiber material with a surface resistivity of 10.-8 Ω / sq up to 10 8 Ω / sq, for example, can be 10 7 Ω / sq, 10 6 Ω / sq, 10 5 Ω / sq etc.

[0048] In some examples, to further improve antistatic performance, the conductivity of the antistatic cleaning component 121 is greater than or equal to 10. 4 S / m, such as the antistatic cleaning component 121, can be made of metal material with a conductivity of 10. 6 S / m to 10 8 S / m, for example, can be 10 7 S / m, 2.2×10 7 S / m, 1.2×10 6 S / m, the antistatic cleaning component 121 can also be made of other materials with certain conductivity, such as conductivity of 5×10³ or 1×10³. 4 , 1.2×103, etc.

[0049] In one feasible implementation, the antistatic cleaning component 121 includes a plurality of strands or clumps of bristles made of carbon fiber material.

[0050] In this technical solution, a material for preparing the antistatic cleaning component 121 is further provided. The bristles of the antistatic cleaning component 121 are made of carbon fiber material. Based on this, the excellent conductivity of carbon fiber material can be used to reduce the generation of static electricity, thereby reducing static electricity on the surface to be cleaned. At the same time, by selecting carbon fiber material, carbon fiber material can have a smaller single filament diameter. Therefore, when the bristles of the antistatic cleaning component 121 rub against the surface to be cleaned, the generation of static electricity can be further reduced. Furthermore, carbon fiber material has strong flexibility, corrosion resistance, wear resistance, and high temperature resistance. Based on this, the wear of the roller brush 100 on the surface to be cleaned can be reduced, while improving the service life of the roller brush 100.

[0051] In this technical solution, the antistatic cleaning component 121 includes several strands or tufts of bristles. This increases the contact efficiency between the antistatic cleaning component 121 and the surface to be cleaned, thereby further improving the efficiency of charge conduction. The charge on the surface to be cleaned is conducted to the cleaning device, thus reducing the total static electricity on the surface and decreasing the adhesion of hair and fine dust to the surface, thereby improving the cleaning effect.

[0052] like Figures 1 to 5As shown, in one feasible embodiment, the antistatic cleaning component 121 includes an antistatic bristle 1211 and a non-antistatic bristle 1212. The surface resistivity of the antistatic bristle 1211 is less than that of the non-antistatic bristle 1212, and the toughness of the non-antistatic bristle 1212 is greater than that of the antistatic bristle 1211.

[0053] In this technical solution, considering that materials with high conductivity usually have low toughness, the antistatic cleaning component 121 may include antistatic bristles 1211 and non-antistatic bristles 1212. The surface resistivity of the antistatic bristles 1211 is less than that of the non-antistatic bristles 1212, and the toughness of the non-antistatic bristles 1212 is greater than that of the antistatic bristles 1211. This can improve the service life of the antistatic cleaning component 121 while ensuring antistatic properties, thereby improving the overall service life of the roller brush 100.

[0054] In one feasible implementation, during the use of the roller brush 100, the non-antistatic bristles 1212 of the same antistatic cleaning component 121 contact the surface to be cleaned before the antistatic bristles 1211.

[0055] In this technical solution, the layout of the antistatic cleaning component 121, including antistatic bristles 1211 and non-antistatic bristles 1212, is further combined so that during the rotation of the roller brush, the more resilient non-antistatic bristles 1212 contact the ground first, followed by the antistatic bristles 1211. Based on this, the non-antistatic bristles 1212 can protect the antistatic bristles 1211 and extend their service life, while the antistatic bristles 1211 can reduce static electricity. Therefore, the antistatic effect can be guaranteed while the service life of the antistatic cleaning component 121 is improved.

[0056] In one feasible implementation, the non-antistatic wool strip 1212 is made of nylon material, and the antistatic wool strip 1211 is made of carbon fiber material.

[0057] In this technical solution, the materials used for the non-antistatic bristle strip 1212 and the antistatic bristle strip 1211 are further provided. The non-antistatic bristle strip 1212, made of nylon, possesses strong toughness, mechanical strength, resilience, and wear resistance, thus better protecting the antistatic bristle strip 1211. The antistatic bristle strip 1211 is made of carbon fiber, which utilizes the excellent conductivity of carbon fiber to reduce static electricity generation on the surface to be cleaned. Furthermore, the selection of carbon fiber allows for a smaller monofilament diameter, further reducing static electricity generation when the bristles of the antistatic cleaning component 121 rub against the surface to be cleaned. Additionally, the carbon fiber material possesses strong flexibility, corrosion resistance, wear resistance, and high-temperature resistance, thereby reducing wear on the surface to be cleaned by the roller brush 100 and increasing its service life.

[0058] In one feasible implementation, the ratio of the monofilament diameter of the antistatic wool sliver 1211 to the monofilament diameter of the non-antistatic wool sliver 1212 is less than or equal to 0.5, wherein the monofilament diameter of the non-antistatic wool sliver 1212 is less than 0.2 mm.

[0059] In this technical solution, the relationship between the monofilament diameters of the antistatic brush strip 1211 and the non-antistatic brush strip 1212 is further provided. The ratio of the monofilament diameter of the antistatic brush strip 1211 to that of the non-antistatic brush strip 1212 is less than or equal to 0.5. This setting makes the monofilament diameter of the non-antistatic brush strip 1212 significantly larger than that of the antistatic brush strip 1211, allowing the non-antistatic brush strip 1212 to better protect the antistatic brush strip 1211, especially to provide shock absorption protection for the antistatic brush strip 1211, thereby further improving the service life of the antistatic cleaning component 121.

[0060] In some examples, the non-antistatic wool strip 1212 can be made of nylon material, and the monofilament diameter can be 0.085mm, 0.1mm, 0.08mm, etc., while the monofilament diameter of the antistatic wool strip 1211 can be 0.007mm to 0.085mm, such as 0.01mm, 0.007mm, 0.008mm, etc. Based on this, the monofilament diameter of the antistatic wool strip 1211 is significantly smaller than that of the non-antistatic wool strip 1212.

[0061] In some examples, the wire diameter of the bristles of the cleaning components 120 other than the antistatic cleaning component 121 can also be smaller than that of the antistatic bristle 1211. For example, the cleaning components 120 other than the antistatic cleaning component 121 can also be made of nylon material, and the monofilament diameter can be 0.2mm to 0.22mm, such as 0.2mm, 0.21mm or 0.22mm, etc. The monofilament diameter of the non-antistatic bristle 1212 is significantly smaller than that of the other cleaning components 120 other than the antistatic cleaning component 121, making the non-antistatic bristle 1212 easier to bend and better protecting the antistatic bristle 1211.

[0062] In one feasible embodiment, the plurality of cleaning components 120 may further include: a support 122 and a non-antistatic cleaning component 123, wherein the support 122 may be made of rubber material and the non-antistatic cleaning component 123 may be made of nylon material; wherein the side of the support 122 that is in contact with the surface to be cleaned may be covered with a cloth.

[0063] In this technical solution, other types of cleaning components are further provided. These other cleaning components may include a support 122 and a non-antistatic cleaning component 123. The support 122 is made of rubber material, and the non-antistatic cleaning component 123 is made of nylon material. Based on this, during the operation of the roller brush 100, the function of the non-antistatic cleaning component 123 is to improve the cleaning ability of dust in the carpet. Therefore, the non-antistatic cleaning component 123 is used to pat the surface to be cleaned, and to move or even pick up the hair on the surface to be cleaned. The function of the support 122 is to support the hair during the rotation of the roller brush 100, thereby reducing the depth of hair embedding into the non-antistatic cleaning component 123. At the same time, when the roller brush 100 rotates, it works in conjunction with the combing action of the comb teeth to reduce the probability of hair getting tangled or knotted on the roller brush 100.

[0064] In some examples, the support 122 may be made of soft rubber, such as silicone.

[0065] In this technical solution, the support member 122 is covered with a cloth on the side that contacts the surface to be cleaned, which can further improve the cleaning effect, increase abrasion resistance, and suppress the generation of static electricity. It is understood that the cloth may include polyester fiber, microfiber, or non-woven fabric.

[0066] like Figure 2 and Figure 4As shown, in one feasible implementation, with respect to each cleaning component 120, the center of the roller body 110 is defined as point O, the end of the cleaning component 120 away from the roller body 110 is defined as point A, the contact point between the cleaning component 120 and the roller body 110 is defined as point B, and the angle OAB is the passive angle; wherein, the passive angle of the antistatic cleaning component 121 is greater than the passive angle of the support component 122, and the passive angle of the antistatic cleaning component 121 is greater than the passive angle of the non-antistatic cleaning component 123.

[0067] In this technical solution, the layout relationship of the antistatic cleaning component 121, the support component 122, and the non-antistatic cleaning component 123 is further provided. The passive angle of the antistatic cleaning component 121 is greater than that of the support component 122 and also greater than that of the non-antistatic cleaning component 123. Based on this, during the operation of the roller brush 100, it is easy to control the interference of the antistatic cleaning component 121, which can protect the bristles of the antistatic cleaning component 121, thereby reducing the probability of the antistatic cleaning component 121 breaking or being damaged, and playing a role in protecting the antistatic cleaning component 121. At the same time, the cleaning effect can be guaranteed by the support component 122 and the non-antistatic cleaning component 123.

[0068] like Figure 2 and Figure 4 As shown, in one feasible embodiment, the passive angle of the antistatic cleaning component 121 is 30° to 80°, and the passive angle of the support 122 and the non-antistatic cleaning component 123 is 0° to 30°.

[0069] In this technical solution, the passive angle of the antistatic cleaning component 121 is further provided to be within a range of 30° to 80°, while the passive angle of the support component 122 and the non-antistatic cleaning component 123 is within a range of 0° to 30°. Based on this, during the operation of the roller brush 100, the interference fit of the antistatic cleaning component 121 can be easily controlled, which can protect the bristles of the antistatic cleaning component 121, thereby reducing the probability of the antistatic cleaning component 121 breaking or being damaged, and playing a role in protecting the antistatic cleaning component 121. At the same time, the cleaning effect can be guaranteed by the support component 122 and the non-antistatic cleaning component 123.

[0070] In one feasible implementation, during the operation of the roller brush 100, the interference fit between the antistatic cleaning component 121 and the surface to be cleaned is greater than the interference fit between the support component 122 and the surface to be cleaned, and the interference fit between the antistatic cleaning component 121 and the surface to be cleaned is greater than the interference fit between the non-antistatic cleaning component 123 and the surface to be cleaned. This ensures the effectiveness of the antistatic cleaning component 121 in removing static electricity.

[0071] In some examples, the interference fit between the support 122 and the surface to be cleaned is less than or equal to -0.3 mm, meaning the interference fit between the support 122 and the surface to be cleaned can be negative, allowing for a slight gap between the support 122 and the surface to be cleaned during operation. The interference fit between the non-antistatic cleaning component 123 and the surface to be cleaned is 0.5 mm to 1.0 mm, while the interference fit between the antistatic cleaning component 121 and the surface to be cleaned is 1.5 mm to 2.5 mm. A slightly larger interference fit for the antistatic cleaning component 121 can improve the antistatic effect.

[0072] In some examples, a limiting groove can be formed on the roller 110, and the passive angle of the cleaning element 120 and the interference with the surface to be cleaned can be adjusted by different limiting groove specifications or based on the parameters of the cleaning element 120 itself.

[0073] like Figure 6 As shown, a second aspect of the present application provides a cleaning device, comprising: a roller brush 100 as described in any of the above technical solutions.

[0074] The cleaning device provided in this application includes the roller brush 100 of any of the above-described technical solutions, and therefore has all the beneficial effects of the roller brush 100 of the above-described technical solutions, which will not be elaborated here.

[0075] In some examples, the cleaning device may also include a body 200, with a roller brush 100 rotatably connected to the body 200. The body 200 can provide a negative pressure environment for the roller brush 100, which can generate a certain suction force on the hair on the carpet, and some of the hair will be directly sucked into the cleaning device. The rotation of the roller brush 100 causes the bristles to continuously beat, move, and even pick up the hair on the carpet, bringing it into the suction range of the body 200 and ultimately sucking it into the cleaning device. The cleaning device provided in this application embodiment, by equipping the roller brush 100 with an anti-static cleaning component 121, can reduce static electricity on the surface to be cleaned, thereby improving the hair accumulation effect and improving the cleaning quality of the cleaning device.
