Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a roller brush and surface cleaning equipment. Background Art

[0002] Roller brushes with a leather strap are typically used to clean furniture such as mattresses, carpets, or sofas. Surface cleaning equipment typically includes a main body, which houses a suction motor and defines a suction port. A roller brush is located at the port. The rotation of the roller brush creates a beating force that strikes the surface to be cleaned. The suction motor generates a suction airflow that flows through the port and collects dirt such as hair, dander, and dust into a dust cup.

[0003] As more and more people keep pets, the amount of hair in their homes will increase. Because animal hair is short and soft, it is difficult to be sucked into the dust cup of the mite remover after it sticks to items such as bed sheets. Ordinary roller brushes have difficulty in cleaning the hair. Utility Model Content

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0044] refer to Figure 1-3 The figure discloses a surface cleaning device 100, which can be a mite remover, a handheld vacuum cleaner, an upright vacuum cleaner, a sweeping robot, etc. The surface cleaning device 100 includes a suction port 20 and a roller brush 10 arranged at the suction port 20.

[0045] refer to Figure 4-7The roller brush 10 generally includes a roller bracket 12 and at least one flapping member 13 installed on the roller bracket 12. The roller bracket 12 generally includes a cylindrical barrel and cover plates arranged at both ends of the barrel. The barrel is generally arranged to be a hollow structure, which can save materials and reduce the weight of the roller brush 10. The barrel can be formed by integral die-casting of aluminum material, and the barrel can also be made of plastic injection molding. The specific process will not be described in detail here. An installation space 14 is defined on the roller bracket 12. The installation space 14 is generally T-shaped, but of course it can also be any other shape, as long as it matches the flapping member 13. The flapping member 13 is generally molded from a plastic material and has a certain degree of flexibility. The flapping member 13 is installed in the installation space 14, and the flapping member 13 is configured to contact the surface to be cleaned during the rotation of the roller bracket 12. Specifically, after one end of the flapping member 13 in the longitudinal direction is installed in the installation space 14, the flapping member 13 is then moved along the longitudinal direction of the installation space 14 until it is installed.

[0046] refer to Figure 8-14 In one embodiment, the flapping member 13 includes a flapping body 19 and a mounting end 131 and a flapping end 132 respectively provided at both ends of the flapping body 19. The mounting end 131 is used to install the flapping member 13 in the installation space 14. After the flapping member 13 is installed in the installation space 14, the flapping end 132 is suspended relative to the roller bracket 12. The flapping end 132 includes a first flapping structure 17, and the first flapping structure 17 includes a plurality of spherical protrusions 171 provided along the length direction of the flapping member 13. By providing a plurality of spherical protrusions 171, the surface to be cleaned can be effectively flapped, so that hair, dust, etc. leave the mattress surface to be cleaned, and are sucked into the dust cup under the dual action of the roller brush 10 and the suction airflow.

[0047] refer to Figure 10 and 11 Furthermore, two adjacent spherical protrusions 171 are in contact with each other, which can prevent hair and the like from being stuck between the two spherical protrusions 171. In order to improve the beating effect, the two adjacent spherical protrusions 171 partially overlap, so that the outer contour of the first beating structure 17 is wavy, which can effectively improve the cleaning ability.

[0048] refer to Figure 9 In order to further improve the flapping ability, the radius of the spherical protrusion 171 is greater than the width of the flapping body 19.

[0049] Continue to refer Figure 8-14 To further enhance the hair removal capability, a second flapping structure 18 is provided between the flapping end 132 and the mounting end 131. The second flapping structure 18 includes a plurality of cylindrical protrusions 181 spaced apart along the length of the flapping member 13. The cylindrical protrusions 181 can effectively remove hair from items such as mattresses.

[0050] The cylindrical protrusion 181 is at a preset angle with respect to the beating body 19, and the preset angle is less than 45 degrees. A certain distance is maintained between the end of the cylindrical protrusion 181 and the beating body 19, so that the cylindrical protrusion 181 can be easily bent at a certain angle to improve the hair removal effect.

[0051] Along the rotation direction of the roller brush 10 ( Figure 5 (In the direction indicated by the middle arrow), the second flapping structure 18 contacts the surface to be cleaned before the first flapping structure 17. This way, the cylindrical protrusions 181 first scrape hair and other long, thin debris off the surface, such as a mattress, or pick up hair and other long, thin debris, which are then rolled toward the suction port by the spherical protrusions 171. The hair and other debris are then drawn into the dust cup by the suction airflow. To ensure that the two flapping structures can clean the same plane of the surface to be cleaned, the apex of the first flapping structure 17 and the apex of the second flapping structure 18 are substantially aligned along the radial direction of the flapping body 19.

[0052] refer to Figure 15 , you can also refer to 10-13. In another embodiment, the roller brush 10 includes a roller bracket 12 and a beating member 13. The shape and manufacturing process of the roller bracket 12 are the same as those in the above embodiment and will not be described in detail here. The beating member 13 is generally made of plastic molded and has a certain flexibility. An installation space 14 is defined on the roller bracket 12. The beating member 13 is installed in the installation space 14, and the beating member 13 is configured to contact the surface to be cleaned during the rotation of the roller bracket 12. The beating member 13 includes a mounting end 131 and a first beating structure 17 and a second beating structure 18 arranged on the mounting end 131. There is a preset angle between the first beating structure 17 and the second beating structure 18. In a specific embodiment, the preset angle is less than 45°. The preset angle can be adjusted according to actual conditions. Along the rotation direction of the roller brush 10, the second beating structure 18 contacts the surface to be cleaned before the first beating structure 17. The second beating structure 18 includes a plurality of columnar protrusions 181, which are arranged at intervals along the length direction of the beating member 13. During the rotation of the roller brush 10, the second beating structure 18 will first contact the surface to be cleaned, pick up hair and other slender debris, and then beat the surface to be cleaned through the first beating structure 17. Then, under the action of the suction airflow, the debris is sucked into the dust cup. The first beating structure 17 can be an ordinary leather strap structure. Figure 15 In order to improve the beating force, the end of the first beating structure 17 may include a plurality of spherical protrusions 171 arranged along the length direction of the beating member 13. The spherical protrusions 171 can effectively improve the beating force.

[0053] Furthermore, two adjacent spherical protrusions 171 are in contact with each other, which can prevent hair and the like from getting stuck between the two spherical protrusions 171. In order to improve the beating effect, the two adjacent spherical protrusions 171 partially overlap, so that the outer contour of the first beating structure 17 is wavy, which can effectively improve the cleaning ability.

[0054] In order to further improve the flapping ability, the radius of the spherical protrusion 171 is greater than the width of the flapping body 19.

[0055] In order to enable the two flapping structures to clean the surface to be cleaned in the same plane, along the radial direction of the flapping body 19, the apex of the first flapping structure 17 and the apex of the second flapping structure 18 are substantially flush.

[0056] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented.
