Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and particularly provides a roller brush assembly and a floor cleaning device. Background Art

[0002] With the continuous upgrading of consumption concepts, users' demands for household cleaning products have also become more diversified and personalized. Take floor cleaning products for example. From the traditional forms of manual cleaning such as mops and brooms, it has gradually transitioned to automated mechanical cleaning forms such as floor sweeping robots and floor washing machines. The emergence of such products has greatly improved the convenience of users' lives and made household cleaning no longer a heavy labor burden.

[0003] For household handheld floor washing machine products, in order to improve the cleaning efficiency of the roller brush, in related technologies, electric heating components such as heating films and heating wires are added between the roller and the roller brush. These electric heating components can be used to heat the brush cloth of the roller brush to achieve the cleaning effect of "high-temperature scrubbing". In order to supply power to the electric heating components, generally a wire groove is provided on the side wall of the connection head of the roller, and the power supply wires of the electric heating components are placed in the wire groove.

[0004] However, when the power supply wires of the electric heating components are placed in the wire groove, it is necessary to waterproof the wire groove to prevent water from flowing into the connection head through the wire groove and causing electric leakage. At the same time, the wire groove is not hermetically arranged, and part of the power supply wires are exposed outside. Inevitably, when the floor washing machine is working, it will collide with the corner of the wall, table legs, etc., and there is a risk of damage to the power supply wires.

[0005] Correspondingly, the field needs a new technical solution to solve the above problems. Summary of the Utility Model

[0035] As Figures 1-4 shown, in order to solve the problem that the setting method of the power supply line of the existing electric heating component is likely to cause leakage at the connection head, the present invention provides a roller brush assembly, including a roller 1, a brush 4 and an electric heating component. A first connector 2 is arranged at one end of the roller 1, a second connector 3 is arranged at the other end of the roller 1, and a wire hole 11 is arranged at a position on the roller 1 between the first connector 2 and the second connector 3. The brush 4 is arranged outside the roller 1, and the electric heating component is arranged between the roller 1 and the brush 4. The electric heating component is arranged to be able to heat the brush 4, and the power supply line of the electric heating component (not shown in the figure) is arranged to be able to pass through the wire hole 11. In this way, the electric heating component can heat the brush 4, the roller 1 is provided with a wire hole 11, and the power supply line of the electric heating component can pass through the wire hole 11, making it more convenient to supply power to the electric heating component through the wire hole 11, effectively shortening the length of the power supply line and reducing the possibility of the power supply line malfunctioning. The power supply line is located inside the roller 1, avoiding collisions between the external environment and the power supply line, and further ensuring the safety of the power supply line. At the same time, the power supply line will not come into contact with water, avoiding water entering the inside of the roller 1 along the power supply line and causing leakage.

[0036] As Figure 1 and 2As shown, in one or more embodiments, the rotary brush assembly includes a drum 1, a brush 4, and an electric heating component. In Figure 1 , a first connector 2 is provided at the right end of the drum 1, and a second connector 3 is provided at the left end of the drum 1. A wire hole 11 is provided at a position between the first connector 2 and the second connector 3 on the drum 1. The wire hole 11 is rectangular, the long side of the wire hole 11 is less than or equal to 23 mm, the short side of the wire hole 11 is less than or equal to 8 mm, and the long side of the wire hole 11 is arranged along the length direction of the drum 1. The distance between the left end of the wire hole 11 and the left end of the drum 1 is equal to the distance between the right end of the wire hole 11 and the right end of the drum 1. In this way, the wire hole 11 is relatively far from both ends of the drum 1, so that even if water enters between the electric heating component and the drum 1, it will not easily enter the drum 1 through the wire hole 11.

[0037] It should be noted that the above setting of the drum 1 is not unique, and those skilled in the art can select the specific structure of the drum 1 based on the specific application scenario. For example, in Figure 1 , the connection positions of the first connector 2 and the second connector 3 can be interchanged, the right end of the drum 1 is connected to the second connector 3, and the left end of the drum 1 is connected to the first connector 2. For another example, the wire hole 11 can be circular, elliptical or polygonal, etc. For another example, when the wire hole 11 is rectangular, the long side of the wire hole 11 can be 23 mm, 20 mm, 17 mm, 10 mm, etc.; the short side of the wire hole 11 can be 8 mm, 7 mm, 6 mm, 5 mm, etc., as long as it can allow the power supply wire to pass through. For another example, the long side of the wire hole 11 can be arranged at an angle with the length direction of the drum 1. For another example, as long as the wire hole 11 is located between the first connector 2 and the second connector 3, the wire hole 11 can also be located at other positions between the first connector 2 and the second connector 3.

[0038] As Figure 2 and 3 shown, in one or more embodiments, the first connector 2 includes a connector body 21, a bearing 23, a drum connector 25, and a fixing seat 24.

The second power supply connector 262 is disposed at the left end of the first connector 2 (as Figure 2 shown). Specifically, the second power supply connector 262 is connected to the second power supply hole on the fixing seat 24. When the first connector 2 is installed inside the roller 1, the first power supply connector 261 and the second power supply connector 262 are electrically connected.

[0041] It should be noted that the first power supply connector 261 and the second power supply connector 262 are magnetic wire connectors. Specifically, the magnetic wire connector includes a male end and a female end, and the first power supply connector 261 and the second power supply connector 262 respectively correspond to the male end and the female end. Magnets are provided on both the male end and the female end, and the male end and the female end can be attracted and contacted with each other. On the contacting end surface, a spring pin is provided on the male end, and a contact point is provided on the female end. When the male end and the female end are attracted and combined, the spring pin contacts the contact point, thereby enabling electrical conduction. Of course, the above is only a simple introduction to the first power supply connector 261 and the second power supply connector 262, and the specific structure is the prior art and will not be elaborated here.

[0042] It should be further noted that the setting of the connecting seat 27, the first power supply connector 261, and the second power supply connector 262 is not necessary, and those skilled in the art can select whether to set the connecting seat 27, the first power supply connector 261, and the second power supply connector 262 and the specific structures of the connecting seat 27, the first power supply connector 261, and the second power supply connector 262 based on the specific application scenario. Of course, the connecting seat 27, the first power supply connector 261, and the second power supply connector 262 may not be provided either.

[0043] In one or more embodiments, a conductive slip ring 22 is fixedly connected within a fixed cylinder 212. One end of the conductive slip ring 22 is electrically connected to a second power supply connector 262, and the other end of the conductive slip ring 22 is electrically connected to a power source. Thus, power supply to the second power supply connector 262 is achieved. The second power supply connector 262 is electrically connected to a first power supply connector 261, and the first power supply connector 261 is electrically connected to a heating component through a power supply line, thereby achieving power supply to the heating component.

[0044] It should be noted that the conductive slip ring 22 is divided into a rotating part and a fixed part. Relative rotation can occur between the rotating part and the fixed part, and electrical connection can be maintained while rotating. The specific structure of the conductive slip ring 22 is prior art and will not be elaborated here. In this case, the fixed part of the conductive slip ring 22 is fixedly connected to the inner wall of the fixed cylinder 212. The wire on the fixed part is electrically connected to the power source, and the wire on the rotating part is electrically connected to the second power supply connector 262. Of course, the conductive slip ring 22 may not be provided, and a fixed ring and an elastic piece may be used. The fixed ring is connected to the fixed part, and the elastic piece is connected to the rotating part. The elastic piece remains in contact with the fixed ring under the action of elasticity.

[0045] In one or more embodiments, the second connector 3 includes a head 31 and a connecting protrusion 32. The head 31 is a tubular shape with one end sealed, and the sealed end of the head 31 is inserted into the drum 1. The number of connecting protrusions 32 is multiple, and the multiple connecting protrusions 32 are evenly spaced along the axial direction of the head 31 and arranged within the head 31. When the drum 1 assembly is installed on the floor washer main body, the driving gear of the motor assembly on the floor washer main body is inserted into the head 31, and the driving gear abuts against the connecting protrusion 32, so that the driving shaft can drive the drum 1 to rotate when rotating.

[0046] It should be noted that the setting of the second connector 3 is not unique, and those skilled in the art can select the specific structure of the second connector 3 based on the specific application scenario. For example, a groove is provided within the head 31, as long as the driving shaft can be assembled with the head 31 so that the driving shaft can drive the drum 1 to rotate.

[0047] In one or more embodiments, the heating component includes a heating film. The heating film is coated on the outer side of the drum 1, located between the brush 4 and the drum 1, and the heating film can heat the brush 4. The heating film is electrically connected to the power supply line, and power is supplied to the heating film through the power supply line.

[0048] It should be noted that it is not necessary to include a heating film in the heating component. The heating film may not be provided either. A heating groove is provided on the outer side of the drum 1. The heating component uses a heating rod or a heating wire, etc. The heating component is placed in the heating groove, as long as it can heat the brush 4.

[0049] Refer to Figure 4, this application also discloses a floor cleaning device, including a base 5 and the above-mentioned brush roller assembly. A placement part for placing the brush roller assembly is provided on the base 5. The brush roller assembly is arranged in the placement part and connected to the base 5. In this way, the electric heating component can heat the brush 4. A wire hole 11 is provided on the drum 1, and the power supply wire of the electric heating component can pass through the wire hole 11, which makes it more convenient to supply power to the electric heating component through the wire hole 11, effectively shortening the length of the power supply wire and reducing the possibility of the power supply wire malfunctioning. The power supply wire is located inside the drum 1, avoiding collisions between the external environment and the power supply wire, and further ensuring the safety of the power supply wire. At the same time, the power supply wire will not come into contact with water, preventing water from entering the inside of the drum 1 along the power supply wire and causing electric leakage.

[0050] In one or more embodiments, the floor cleaning device is preferably a floor washer, and of course, it can also be a sweeping robot or a mopping robot.

[0051] Those skilled in the art can understand that although some of the embodiments described herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of this application and forms different embodiments. For example, in the claims of this application, any one of the claimed embodiments can be used in any combination.
