Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] Combination Figures 1 to 3 The floor brush assembly 100 according to an embodiment of the present invention includes a housing 10 and a roller brush 20. Exemplarily, the floor brush assembly 100 can be installed in cleaning equipment such as a robot vacuum cleaner or a vacuum cleaner.

[0031] Combination Figure 2 and Figure 3The housing 10 has a receiving cavity 11 and an air intake 12 disposed on the side of the receiving cavity 11. The roller brush 20 includes a main body 21, a first cleaning element 22, and a second cleaning element 23. The main body 21 is rotatably disposed in the receiving cavity 11, and the first cleaning element 22 and the second cleaning element 23 are disposed in the main body 21. The first cleaning element 22 and the second cleaning element 23 rotate with the main body 21 to clean the working surface, and the first cleaning element 22 and the second cleaning element 23 are arranged along the rotation direction of the main body 21. Specifically, the housing 10 can be used to accommodate and protect the roller brush 20. When the roller brush 20 rotates, it drives the dirt to separate from the working surface and sucks it into the cleaning equipment through the air intake 12. The first cleaning element 22 and the second cleaning element 23 are arranged along the rotation direction of the main body 21, combined with... Figure 3 As shown, the main body 21 can rotate in the direction of A1→A2. When the main body 21 rotates, the first cleaning component 22 and the second cleaning component 23 cooperate to clean the working surface.

[0032] The first cleaning component 22 extends along the axial direction of the roller brush 20 and is configured to drive the dirt on the working surface toward the air intake 12 when rotating in the rotation direction. The first cleaning component 22 enables the roller brush 20 to gather dirt toward the air intake 12 during rotation, so that the dirt can be sucked into the cleaning equipment through the air intake 12, thereby improving the cleaning effect of the floor brush assembly 100 and improving the efficiency of the cleaning equipment in cleaning the working surface.

[0033] According to the embodiment of the present utility model, the floor brush assembly 100 includes a first cleaning component 22 and a second cleaning component 23 arranged along the rotation direction of the main body 21. The first cleaning component 22 can drive the dirt on the working surface to gather toward the air intake 12, so that the roller brush 20 gathers the dirt toward the air intake 12 during rotation, thereby improving the efficiency of the floor brush assembly 100 in cleaning garbage and thus improving the cleaning efficiency of the cleaning equipment.

[0034] The first cleaning component 22 is configured to drive the dirt on the working surface to gather toward the air intake 12 when rotating in the rotation direction. The first cleaning component 22 can be configured as an arc-shaped structure or a V-shaped structure, etc. The shape of the second cleaning component 23 can be adapted to the shape of the second cleaning component 23.

[0035] Furthermore, the first cleaning component 22 and the second cleaning component 23 are arranged along the rotation direction of the main body 21. For example, the number of the first cleaning component 22 and the number of the second cleaning component 23 are both one; or, the number of the first cleaning component 22 and the second cleaning component 23 are both at least two, and the first cleaning component 22 and the second cleaning component 23 are arranged alternately in the rotation direction, so that the first cleaning component 22 and the second cleaning component 23 can cooperate to improve the cleaning effect on the dirt on the working surface.

[0036] Combination Figure 3In some embodiments of this utility model, the first cleaning component 22 includes a first segment 22a and a second segment 22b, which are distributed along the axial direction of the main body 21. The opposite ends of the first segment 22a and the second segment 22b are inclined in the opposite direction of rotation. Specifically, the main body 21 can rotate in the direction A1→A2, and the opposite ends of the first segment 22a and the second segment 22b are inclined in the direction A2→A1. For example, the main body 21 may include a first end and a second end that are axially opposite each other. The main body 21 can rotate in a counterclockwise direction, and the main body 21 drives the first cleaning component 22 and the second cleaning component 23 to rotate in a counterclockwise direction. The first segment 22a is disposed near the first end, and the second segment 22b is disposed near the second end. The first segment 22a is inclined in a clockwise direction from the first end to the second end, and the second segment 22b is inclined in a clockwise direction from the second end to the first end. During the rotation of the main body 21, the first segment 22a and the second segment 22b cooperate to gather the dirt on the working surface from both ends to the middle, so as to prevent the garbage near the end from being unable to be effectively sucked into the air intake 12, thereby improving the cleaning effect of dirt on the working surface.

[0037] Combination Figure 2 and Figure 3 Furthermore, the ends of the first segment 22a and the second segment 22b near the second segment 22b are opposite to the air inlet 12 along the rotation direction. During the rotation of the main body 21, the first segment 22a and the second segment 22b work together to gather the garbage towards the air inlet 12, further improving the effect of the roller brush 20 in gathering dirt towards the air inlet 12. After the garbage is gathered, it can be smoothly sucked into the cleaning equipment through the air inlet 12, thereby improving the cleaning efficiency of the cleaning equipment.

[0038] In some embodiments of this utility model, the end of the first segment 22a near the second segment 22b and the end of the second segment 22b near the first segment 22a are connected; or, the end of the first segment 22a near the second segment 22b and the end of the second segment 22b near the first segment 22a are spaced apart. Exemplarily, the first segment 22a and the second segment 22b can be integrally formed, facilitating the processing and forming of the first cleaning component 22; or, the first segment 22a and the second segment 22b can be a separate structure, facilitating the installation of the first cleaning component 22 and improving the assembly efficiency of the floor brush assembly 100.

[0039] Combination Figure 4 In some embodiments of this utility model, the first segment 22a and the second segment 22b are connected in a V-shape. The cooperation of the first segment 22a and the second segment 22b can improve the collection effect of dirt, thereby making it easier to suck the dirt into the cleaning equipment through the air intake 12 and improve the cleaning efficiency of the floor brush assembly 100.

[0040] The shape of the second cleaning component 23 matches the shape of the first cleaning component 22. The second cleaning component 23 may include a third segment and a fourth segment, which may be connected to form a V-shape.

[0041] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the first cleaning component 22 includes at least two components, and the second cleaning component 23 includes at least two components. The first cleaning components 22 and the second cleaning components 23 are arranged alternately along the rotation direction of the main body 21. Specifically, during the rotation of the main body 21, the first cleaning components 22 and the second cleaning components 23 are driven to rotate. The first cleaning components 22 and the second cleaning components 23 are arranged alternately along the rotation direction, which facilitates the collection of dirt on the working surface by multiple first cleaning components 22 during rotation, thereby facilitating the suction of the waste into the cleaning equipment through the suction port 12. Exemplarily, the number of first cleaning components 22 can be two, three, four, etc., and the number of second cleaning components 23 corresponds to the number of first cleaning components 22.

[0042] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the outer edge of the first cleaning member 22 is lower than the outer edge of the second cleaning member 23. Specifically, in the radial direction of the roller brush 20, the maximum outer diameter of the first cleaning member 22 is smaller than the maximum outer diameter of the second cleaning member 23. In other words, during the rotation of the roller brush 20, the second cleaning member 23 contacts the working surface to separate the dirt from the working surface, while the first cleaning member 22 does not contact the working surface. When there is hair on the working surface, the first cleaning member 22 can, on the one hand, gather the hair towards the suction port 12, making it easier to suck the hair into the cleaning device through the suction port 12. On the other hand, because the outer edge of the first cleaning member 22 is lower than the outer edge of the second cleaning member 23, when the hair is sucked between the two sides of the second cleaning member 23 in the circumferential direction, the first cleaning member 22 can support the hair, so that a gap is formed between the hair and the main body 21, preventing the hair from getting tangled. The roller brush 20 is designed to prevent tangling. In related technologies, the roller brush 20 is usually made of full bristles. During use, hair will get tangled on the bristles of the roller brush 20. Once a large amount of hair gets tangled on the roller brush 20, the cleaning efficiency of the roller brush 20 will decrease and the cleaning effect will be poor. At the same time, the tangled hair will also affect the rotation of the roller brush 20. If it is not cleaned in time, it will easily cause the roller brush 20 to jam. In related technologies, blades are used to cut the hair to reduce hair tangling. Compared with the structure of setting blades to cut, the present invention simplifies the structure of the floor brush assembly 100 and improves the cleaning efficiency of the floor brush assembly 100 on the working surface.

[0043] For example, the first cleaning component 22 can be a rubber strip, and the second cleaning component 23 can be a bristle strip. During the rotation of the main body 21, the bristle strip contacts the working surface to clean the dirt on the working surface. The rubber strip can gather the dirt from both ends of the suction port 12, improving the cleaning effect of the floor brush assembly 100. When there is hair on the working surface, the rubber strip can be used to support the hair, making it easier to be sucked into the suction port 12 under the action of suction force, thus preventing the hair from getting tangled in the roller brush 20. In addition, the outer edge of the first cleaning component 22 is lower than the outer edge of the second cleaning component 23, which can protect the second cleaning component 23, prevent the rubber strip from rubbing against the working surface and causing wear on the rubber strip, thereby improving the service life of the rubber strip.

[0044] Combination Figure 5 In some embodiments of this utility model, the outer peripheral surface of the main body 21 is provided with a first positioning groove 211, and the first cleaning component 22 includes a sweeping part 221 and an installation part 222. The installation part 222 is connected to the sweeping part 221 and is embedded in the first positioning groove 211. Specifically, the sweeping part 221 can be used to gather dirt towards the air intake 12, and the installation part 222 can be used to position the first cleaning component 22 to the main body 21. By setting the installation part 222 and the first positioning groove 211, it is convenient to install the first cleaning component 22 to the main body 21, thereby improving the assembly efficiency of the floor brush assembly 100.

[0045] Furthermore, the outer peripheral surface of the main body 21 is also provided with a first protruding edge 212 and a second protruding edge 213 arranged circumferentially around the main body 21. A second positioning groove 214 is defined between the first protruding edge 212 and the second protruding edge 213. The second positioning groove 214 is connected to the first positioning groove 211. At least a portion of the cleaning part 221 is positioned in the second positioning groove 214. The first protruding edge 212 and the second protruding edge 213 cooperate to position the cleaning part 221, reducing the deformation of the cleaning part 221 during the cleaning process, thereby facilitating the stable collection of debris by the first cleaning component 22 towards the suction port 12. In addition, the first positioning groove 211 is connected to the second positioning groove 214, which facilitates the installation of the first cleaning component 22 onto the main body 21. For example, the first cleaning component 22 is installed onto the main body 21 from the end of the main body 21.

[0046] In addition, in conjunction with the foregoing, the outer edge of the first cleaning member 22 may be lower than the outer edge of the second cleaning member 23. The first protruding edge 212 and the second protruding edge 213 can reduce the deformation of the cleaning part 221 during the cleaning process, thereby making it easier for the first cleaning member 22 to support the hair and prevent the hair from getting tangled in the roller brush 20, thereby improving the anti-tangling effect of the roller brush 20.

[0047] The first positioning groove 211 has a smaller circumferential dimension than the second positioning groove 214, which prevents the mounting part 222 from coming off the first positioning groove 211 and improves the connection stability between the first cleaning part 22 and the main body 21.

[0048] Combination Figure 2 and Figure 6 In some embodiments of this utility model, the floor brush assembly 100 further includes a flexible support member 30. The flexible support member 30 protrudes from the bottom surface of the housing 10, is relatively stationary with respect to the housing 10, and is arranged on both sides of the roller brush 20 along the axial direction. In related technologies, rollers are usually installed on the bottom surface of the housing 10. During the rolling process, hair easily gets tangled in the rollers, requiring user cleaning, and prolonged use can easily cause the rollers to jam. This utility model, by providing the flexible support member 30, ensures that the flexible support member 30 contacts the working surface when the floor brush assembly 100 moves on the working surface, and that the flexible support member 30 is relatively stationary with respect to the housing 10, thus preventing hair from getting tangled in the flexible support member 30 and solving the problem of hair tangling.

[0049] The flexible support 30 can be made of silicone, a brush, or Teflon, etc., to reduce the pushing resistance of the floor brush assembly 100 and make it easier for the floor brush assembly 100 to slide relative to the working surface.

[0050] Combination Figure 2 Furthermore, in the orthographic projection of the plane containing the bottom surface of the housing 10, the axis (B) of the roller brush 20 passes through the flexible support member 30; or, in the orthographic projection of the plane containing the bottom surface of the housing 10, the flexible support member 30 is located on the front side of the axis (B) of the roller brush 20, so as to facilitate the stable rotation of the roller brush 20 by supporting it through the flexible support member 30.

[0051] It should be noted that, in this application, the front side refers to the side of the area to be cleaned that the floor brush assembly 100 first contacts when cleaning the work surface; the rear side refers to the side of the cleaning area that the floor brush assembly 100 passes over after cleaning the work surface.

[0052] The roller brush 20 has flexible support members 30 on both sides. The axis (B) of the roller brush 20 passes through the flexible support member 30, or the flexible support member 30 is located in front of the axis (B) of the roller brush 20. The rear side of the roller brush 20 can be provided with a rear wheel or a small wheel to contact the working surface. When the floor brush assembly 100 moves on the working surface to be cleaned, the front area of ​​the bottom surface of the floor brush assembly 100 contacts the working surface to be cleaned by the flexible support member 30. The rear area of ​​the floor brush assembly 100 can contact the working surface by setting a rear wheel or a small wheel. Since the front side of the floor brush assembly 100 contacts the dirt on the working surface first during the cleaning process, it can prevent hair from getting tangled in the flexible support member 30. In addition, by setting the first cleaning member 22, the cleaning effect on dirt can be improved and the risk of hair getting tangled in the rear wheel or small wheel can be reduced.

[0053] Combination Figure 2In some embodiments of this utility model, the flexible support member 30 includes flexible protrusions 31, which prevent hair from getting tangled in the floor brush assembly 100 and can support the roller brush 20, reducing the pushing resistance of the floor brush assembly 100 and making it easier for the floor brush assembly 100 to slide relative to the working surface. For example, the flexible protrusions 31 can be made of materials such as silicone or Teflon.

[0054] Combination Figure 2 In some embodiments of this utility model, the flexible support member 30 includes a bristle portion 32, which prevents hair from getting tangled in the floor brush assembly 100 and can support the roller brush 20, reducing the pushing resistance of the floor brush assembly 100 and making it easier for the floor brush assembly 100 to slide relative to the working surface.

[0055] In some embodiments of this utility model, the flexible support member 30 may include a flexible protrusion 31 and a bristle portion 32, which improves the support effect of the flexible support member 30 on the floor roller brush 20 and reduces the pushing resistance of the floor brush assembly 100.

[0056] Combination Figure 2 and Figure 6 In some embodiments of this utility model, the housing 10 also has a side air inlet 13 that connects to the receiving cavity 11. The side air inlet 13 is arranged on both sides of the roller brush 20 along the axial direction. In the orthographic projection of the bottom surface of the housing 10, the side air inlet 13 is located on the rear side of the axis of the roller brush 20. During the operation of the cleaning device, the airflow can enter the receiving cavity 11 from the side air inlet 13. The airflow entering from the side air inlet 13 can guide hair and other dirt to gather towards the air inlet, improve the efficiency of the first cleaning component 22 in driving dirt to gather towards the air inlet 12, and further improve the cleaning efficiency and cleaning effect of the floor brush assembly 100.

[0057] In some embodiments of this utility model, the first cleaning component 22 is configured as an adhesive strip, which can improve the efficiency of the first cleaning component 22 in gathering dirt on the working surface toward the air intake 12.

[0058] In some embodiments of this utility model, the second cleaning component 23 is a bristle brush. During the rotation of the main body 21, the bristle brush can brush up the dirt on the working surface, thereby improving the cleaning efficiency of the working surface.

[0059] This utility model also proposes a cleaning device, including the aforementioned floor brush assembly 100. Exemplarily, the cleaning device may include a suction device for providing negative pressure. When the suction device operates, it generates negative pressure at the air intake 12. By setting the aforementioned floor brush assembly 100, dirt can be gathered towards the air intake 12, improving the cleaning effect and efficiency of the cleaning device.
