Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a roller brush, cleaning equipment, and cleaning system. Background Technology

[0002] In related technologies, the mopping components of a roller brush in cleaning equipment can be heated by a heating element to simulate the cleaning principle of a heated cloth wiping a surface, thereby improving the cleaning efficiency and effectiveness of stubborn stains and grease on the floor. Currently, multiple heating elements are typically spaced circumferentially along the roller brush to facilitate uniform heat distribution. However, after being powered on, because multiple heating elements heat the mopping components of the roller brush simultaneously, the heating efficiency of a single heating element is relatively low. In scenarios where the roller brush rotates slowly, such as drying scenarios, the local heating rate of the mopping components is slow, resulting in low drying efficiency. Utility Model Content

[0003] In view of this, embodiments of this application provide a roller brush, a cleaning device, and a cleaning system to solve the problem of low heating efficiency of a single heating element.

[0004] The first aspect of this application proposes a roller brush, comprising:

[0005] Power supply bracket, used to fix it to the base of the cleaning equipment;

[0006] The roller is capable of rotating relative to the power supply bracket in a first direction;

[0007] A mopping component, covering the roller;

[0008] A commutator is disposed on the drum and rotates synchronously with the drum, and at least two conductive parts are arranged at intervals around the first direction on the commutator.

[0009] A heating element is disposed on the drum and rotates synchronously with the drum. At least two heating elements are arranged at intervals around the first direction. Each heating element includes a first connecting conductor and a second connecting conductor. The first connecting conductor and the second connecting conductor of the same heating element are electrically connected to the two conductive parts, respectively.

[0010] A power supply conductor group is disposed on the power supply bracket, and the power supply conductor group includes a first power supply conductor and a second power supply conductor arranged at intervals around the first direction;

[0011] When the commutator rotates relative to the power supply conductor group around the first direction, the first power supply conductor and the second power supply conductor respectively make conductive contact with different conductive parts, so that the plurality of heating elements are energized and heated in sequence.

[0012] The beneficial effects of the roller brush provided in this application embodiment are as follows: The roller brush includes a power supply bracket, a roller, a wiping element, a commutator, a heating element, and a power supply conductor group. The commutator and heating element are mounted on the roller and rotate synchronously with the roller. The power supply conductor group is mounted on the power supply bracket. Since the roller can rotate relative to the power supply bracket in a first direction, the commutator can rotate relative to the power supply conductor group. During the rotation of the commutator relative to the power supply conductor group in the first direction, the first power supply conductor and the second power supply conductor respectively make conductive contact with different conductive parts on the commutator, so that multiple heating elements are energized sequentially to heat the wiping element of the roller brush. Compared with multiple heating elements simultaneously energizing the wiping element of the roller brush, the sequential energization of multiple heating elements results in a faster heating rate for each heating element, solving the problem of slow heating rate of a single heating element. This makes it suitable for applications with slow roller brush rotation speeds, such as drying applications. External air drying and internal heating elements can be used to quickly heat local areas of the roller brush to rapidly dry the wiping element, improving drying efficiency.

The first connecting conductor and the second connecting conductor are electrically connected to the two second conductive areas respectively. When the commutator rotates relative to the power supply conductor group around the first direction, the first power supply conductor and the second power supply conductor make conductive contact with the corresponding first conductive area.

The first connecting conductor and the second connecting conductor of the second heating element are electrically connected to the second conductive part and the third conductive part, respectively. The first connecting conductor and the second connecting conductor of the third heating element are electrically connected to the third conductive part and the first conductive part, respectively.

[0025] In some embodiments, the size of the first power supply conductor is greater than the spacing between two adjacent conductive portions in the first direction, and / or the size of the second power supply conductor is greater than the spacing between two adjacent conductive portions.

[0026] In some embodiments, the heating element is located between the roller and the wiping element.

The second spring contact and the second spring contact are used to elastically contact the positive and negative output portions of the power supply on the base.

[0066] An embodiment of the first aspect of this application provides a roller brush for use in cleaning equipment. Please refer to... Figure 5 and Figure 7 The cleaning device 1 includes a roller brush 100 and a base 200. The roller brush 100 includes a roller brush heating device 10, a roller 20, a mopping component 30, and a power supply bracket 50. The power supply bracket 50 is fixed on the base 200 and located at one axial end of the roller 20. The roller 20 is rotatable about a first direction X, where the first direction X is the extension direction of the rotation axis of the roller 20. The mopping component 30 covers the roller 20 and rotates with the roller 20. For example, the mopping component 30 can be a mop.

[0067] The roller brush heating device 10 is used to heat the mopping component 30. Please refer to... Figure 1 , Figure 2 , Figure 4 and Figure 5 The roller brush heating device 10 includes a commutator 11, a heating element 12, and a power supply conductor group 13.

[0068] The commutator 11 is mounted on the drum 20 and rotates synchronously with the drum 20. At least two conductive parts 113 are arranged on the commutator 11 at intervals around the first direction X.

[0069] For example, please refer to Figure 6 The drum 20 includes a rotating frame 21, which is located at one end of the drum 20, and the commutator 11 is fixed on the rotating frame 21.

[0070] Understandably, the commutator 11 is rotatable about a first direction X. Three, four, five, or more conductive portions 113 may be arranged at intervals around the first direction X on the commutator 11. Each conductive portion 113 is insulated from the others.

[0071] Heating element 12 is disposed on roller 20 and rotates synchronously with roller 20. At least two heating elements 12 are arranged at intervals around the first direction X. Each heating element 12 includes a first connecting conductor 121 and a second connecting conductor 122. The first connecting conductor 121 and the second connecting conductor 122 are electrically connected to two conductive parts 113 respectively.

[0072] Understandably, the heating element 12 can rotate about the first direction X, that is, the commutator 11, the heating element 12, and the roller 20 can rotate together about the first direction X. Among them, the heating element 12 is used to heat the wiping component 30.

[0073] It is understandable that the heating elements 12 can be arranged in two, three, four, or five or more at uniform intervals around the first direction X.

[0074] It is understood that the heating element 12 can be located on the outer wall surface of the drum 20 or on the inner wall surface of the drum 20; or, the heating element 12 can be embedded in the drum wall of the drum 20.

[0075] The first connecting conductor 121 and the second connecting conductor 122 can be a guide rod, a wire, etc.

[0076] The first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 are electrically connected to two conductive parts 113 respectively. It can be understood that the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 can be electrically connected to two adjacent conductive parts 113 respectively; or, the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 can also be electrically connected to two non-adjacent conductive parts 113 respectively.

[0077] The power supply conductor group 13 is disposed on the power supply bracket 50. The power supply conductor group 13 includes a first power supply conductor 131 and a second power supply conductor 132 arranged at intervals around the first direction X.

[0078] The first power supply conductor 131 and the second power supply conductor 132 are arranged at intervals around the first direction X. This can be understood as the central angle between the first power supply conductor 131 and the second power supply conductor 132 being 180°, i.e., they are arranged in a straight line; or the central angle between the first power supply conductor 131 and the second power supply conductor 132 being 30°, 60°, 90°, 120° or 150°, etc.

[0079] During the rotation of the commutator 11 relative to the power supply conductor group 13 around the first direction X, the first power supply conductor 131 and the second power supply conductor 132 respectively make conductive contact with different conductive parts 113, so that the multiple heating elements 12 are energized and heated in sequence.

[0080] The first power supply conductor 131 and the second power supply conductor 132 respectively make conductive contact with different conductive parts 113. For example, when the first power supply conductor 131 makes conductive contact with one of the conductive parts 113, the second power supply conductor 132 makes conductive contact with another or two conductive parts 113, so as to realize the conduction of one or two heating elements 12, so that multiple heating elements 12 are sequentially energized to heat the wiping member 30 of the roller brush 100.

[0081] The beneficial effects of the roller brush 100 provided in this application embodiment are as follows: The roller brush 100 includes a power supply bracket 50, a roller 20, a wiping component 30, a commutator 11, a heating element 12, and a power supply conductor group 13. The commutator 11 and the heating element 12 are disposed on the roller 20 and rotate synchronously with the roller 20. The power supply conductor group 13 is disposed on the power supply bracket 50. Since the roller 20 can rotate relative to the power supply bracket 50 around a first direction X, the commutator 11 can rotate relative to the power supply conductor group 13. During the rotation of the commutator 11 relative to the power supply conductor group 13 around the first direction X, the first power supply conductor 131 and the second power supply conductor 132 respectively make conductive contact with different conductive parts 113 on the commutator 11, so that the multiple heating elements 12 are sequentially energized and heated to heat the wiping component 30 of the roller brush 100. Compared to multiple heating elements 12 simultaneously heating the wiping component of the roller brush 100, multiple heating elements 12 are energized sequentially, resulting in a faster heating rate for each heating element 12. This solves the problem of slow heating rate for a single heating element 12 and is suitable for applications where the roller brush 100 rotates at a slow speed, such as drying applications. External air drying and internal heating elements 12 can be used to quickly heat local areas of the roller brush 100 to dry the wiping component 30 quickly, thereby improving drying efficiency.

[0082] Please refer to Figure 2 and Figure 3 In some embodiments, the commutator 11 includes an insulating cylinder 111 and an insulating ring 112. The insulating cylinder 111 extends along a first direction X, and the insulating ring 112 is disposed at one axial end of the insulating cylinder 111.

[0083] The insulating cylinder 111 extends along the first direction X, that is, the axial direction of the insulating cylinder 111 is the first direction X.

[0084] The insulating ring 112 is located at one axial end of the insulating cylinder 111. It can be understood that the insulating ring 112 and the insulating cylinder 111 are integrally formed; or, the insulating ring 112 is fixed to one axial end of the insulating cylinder 111 by means of welding, pressing, fastener connection, etc.

[0085] The conductive part 113 includes a first conductive region 1131 on the insulating cylinder 111 and a second conductive region 1132 on the insulating ring 112. The first connecting conductor 121 and the second connecting conductor 122 are electrically connected to the two second conductive regions 1132 respectively. When the commutator 11 rotates relative to the power supply conductor group 13 about the first direction X, the first power supply conductor 131 and the second power supply conductor 132 respectively make conductive contact with different first conductive regions 1131.

[0086] The first connecting conductor 121 and the second connecting conductor 122 are electrically connected to the two second conductive regions 1132 respectively. It can be understood that the first connecting conductor 121 and the second connecting conductor 122 can be electrically connected to two adjacent second conductive regions 1132 respectively; or, the first connecting conductor 121 and the second connecting conductor 122 can also be electrically connected to two non-adjacent second conductive regions 1132 respectively.

[0087] It is understood that the second conductive area 1132 can be located on the side of the insulating ring 112 facing the insulating cylinder 111, or the second conductive area 1132 can be located on the side of the insulating ring 112 away from the insulating cylinder 111.

[0088] For example, the insulating ring 112 is a pad, and the first connecting conductor 121 and the second connecting conductor 122 are respectively soldered onto the second conductive area 1132.

[0089] The first power supply conductor 131 and the second power supply conductor 132 respectively make conductive contact with different first conductive areas 1131. For example, when the first power supply conductor 131 makes conductive contact with one of the first conductive areas 1131, the second power supply conductor 132 makes conductive contact with the other or both first conductive areas 1131.

[0090] It is understood that the first conductive area 1131 can be located on the inner wall of the insulating cylinder 111, in which case the first power supply conductor 131 and the second power supply conductor 132 are located inside the insulating cylinder 111; or, the first conductive area 1131 can be located on the outer wall of the insulating cylinder 111, in which case the first power supply conductor 131 and the second power supply conductor 132 are located outside the insulating cylinder 111.

[0091] In other embodiments, the commutator 11 includes an insulating cylinder 111 extending along a first direction X, but does not include an insulating ring 112. A conductive portion 113 is disposed on the outer wall surface of the insulating cylinder 111, and a power supply conductor group 13 is located on the outer side of the insulating cylinder 111; or, the conductive portion 113 is disposed on the inner wall surface of the insulating cylinder 111, and the power supply conductor group 13 is located on the inner side of the insulating cylinder 111.

[0092] Please refer to Figure 2 and Figure 3 In some embodiments, the commutator 11 is provided with a groove 114 located between two adjacent conductive portions 113. The groove 114 is used to separate the two adjacent conductive portions 113.

[0093] For example, when the commutator 11 includes an insulating cylinder 111 and an insulating ring 112, the groove 114 includes a first groove segment 1141 provided on the insulating cylinder 111 and a second groove segment 1142 provided on the insulating ring 112.

[0094] For example, when the commutator 11 includes an insulating cylinder 111 but not an insulating ring 112, the groove 114 includes a first groove segment 1141 provided on the insulating cylinder 111, but does not include a second groove segment 1142 provided on the insulating ring 112.

[0095] Based on the above technical solution, when the commutator 11 rotates relative to the power supply conductor group 13, the metal shavings generated by the friction between the first power supply conductor 131 and the second power supply conductor 132 and the conductive part 113 will enter the groove 114 and be burned off by the electric spark generated in the groove 114, so as to avoid affecting the conductive contact between the first power supply conductor 131 and the second power supply conductor 132 and the conductive part 113.

[0096] In some embodiments, the conductive portion 113 is a conductive layer disposed on the surface of the commutator 11.

[0097] It is understood that the conductive layer can be a coating layer applied to the surface of the commutator 11; or, the conductive layer can be a conductive sheet fixed to the surface of the commutator 11.

[0098] Based on the above technical solution, the conductive layer is relatively thin, which can reduce material costs.

[0099] In other embodiments, the conductive part 113 may be an arc-shaped conductive block disposed on the commutator 11.

[0100] Please refer to Figure 3 In some embodiments, the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 are respectively connected to two adjacent conductive parts 113.

[0101] Based on the above technical solution, the lengths of the first connecting conductor 121 and the second connecting conductor 122 can be reduced, which is beneficial to the arrangement of the first connecting conductor 121 and the second connecting conductor 122.

[0102] In other embodiments, the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 are respectively connected to two non-adjacent conductive parts 113.

[0103] Please refer to Figure 2 In some embodiments, the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 are located at the same end of the heating element 12 about the first direction X.

[0104] In the axial direction of the drum 20, the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 are located at the same end of the heating element 12.

[0105] To improve heating efficiency, the heating element 12 is typically positioned between the roller 20 and the wiping component 30. That is, the heating element 12 is located on the outer wall of the roller 20, while the commutator 11 is located inside the roller 20. Therefore, it is necessary to create perforations on the roller 20 for the first connecting conductor 121 and the second connecting conductor 122 to pass through. By placing the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 at the same end of the heating element 12, the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 can share a perforation, thereby reducing the number of perforations created on the roller 20.

[0106] In other embodiments, the first connecting conductor 121 and the second connecting conductor 122 of the same heating element 12 are located at both ends of the heating element 12 about the first direction X.

[0107] In some embodiments, the heating element 12 is a heating film.

[0108] For example, the heating film is a resistance heating film, such as a PI (Polyimide) resistance heating film.

[0109] Based on the above technical solution, the heating film can be attached to the outer peripheral wall of the roller 20, which is beneficial for fixing the heating film between the roller 20 and the mopping component 30; moreover, the heating film is thin and will not affect the mopping component 30 from covering the roller 20.

[0110] In other embodiments, a receiving groove can be formed on the outer peripheral wall of the roller 20, and the heating element 12 can be an arc-shaped heating plate disposed in the receiving groove.

[0111] Please refer to Figure 2 and Figure 3 In some embodiments, the commutator 11 has three conductive parts 113 arranged at intervals around the first direction X, the three conductive parts 113 being the first conductive part 113a, the second conductive part 113b, and the third conductive part 113c in sequence; the heating element 12 has three arranged at intervals around the first direction X, the three heating elements 12 being the first heating element 12a, the second heating element 12b, and the third heating element 12c in sequence.

[0112] For example, the first conductive portion 113a, the second conductive portion 113b, and the third conductive portion 113c are arranged at uniform intervals around the first direction X on the commutator 11, that is, the first conductive portion 113a, the second conductive portion 113b, and the third conductive portion 113c have the same size.

[0113] For example, the first heating element 12a, the second heating element 12b and the third heating element 12c are arranged at uniform intervals around the first direction X, that is, the sizes of the first heating element 12a, the second heating element 12b and the third heating element 12c are similar, which is conducive to uniformly heating the wiping member 30.

[0114] The first connecting conductor 121 and the second connecting conductor 122 of the first heating element 12a are electrically connected to the first conductive part 113a and the second conductive part 113b, respectively. The first connecting conductor 121 and the second connecting conductor 122 of the second heating element 12b are electrically connected to the second conductive part 113b and the third conductive part 113c, respectively. The first connecting conductor 121 and the second connecting conductor 122 of the third heating element 12c are electrically connected to the third conductive part 113c and the first conductive part 113a, respectively.

[0115] For example, please refer to Figure 3 During the clockwise rotation of the commutator 11 relative to the power supply conductor group 13, firstly, the first power supply conductor 131 makes conductive contact with the first conductive part 113a, and the second power supply conductor 132 makes conductive contact with the second conductive part 113b. At this time, the first heating element 12a is energized to heat the dragging member 30 of the roller brush 100. Then, the first power supply conductor 131 makes conductive contact with both the first conductive part 113a and the third conductive part 113c, and the second power supply conductor 132 makes conductive contact with the second conductive part 113b. At this time, both the first heating element 12a and the second heating element 12b are energized to heat the dragging member 30 of the roller brush 100. Next, the first power supply conductor 131 makes conductive contact with the third conductive part 113c, and the second power supply conductor 132 makes conductive contact with the second conductive part 113b. At this time, the second heating element 12b is energized to heat the dragging member 30 of the roller brush 100. Then, the first power supply conductor 131 makes conductive contact with the third conductive part 113c, and the second power supply conductor 132 simultaneously makes conductive contact with the first conductive part 113a and the second conductive part 113b. At this time, the second heating element 12b and the third heating element 12c are simultaneously energized to heat the wiping element 30 of the roller brush 100. Next, the first power supply conductor 131 makes conductive contact with the third conductive part 113c, and the second power supply conductor 132 makes conductive contact with the first conductive part 113a. At this time, the third heating element 12c is energized to heat the wiping element 30 of the roller brush 100. Next, the first power supply conductor 131 simultaneously makes conductive contact with the third conductive part 113c and the second conductive part 113b, and the second power supply conductor 132 makes conductive contact with the first conductive part 113a. At this time, both the third heating element 12c and the first heating element 12a are energized to heat the wiping element 30 of the roller brush 100. Finally, the first power supply conductor 131 makes conductive contact with the second conductive part 113b, and the second power supply conductor 132 makes conductive contact with the first conductive part 113a. At this time, the first heating element 12a is energized to heat the mopping element 30 of the roller brush 100. Under this energized condition, the mopping element 30 of the roller brush 100 will be heated evenly and quickly to the required temperature to achieve the purpose of high-temperature mopping.

[0116] In some embodiments, the size of the first power supply conductor 131 is greater than the spacing between two adjacent conductive portions 113 in the first direction X, and the size of the second power supply conductor 132 is greater than the spacing between two adjacent conductive portions 113.

[0117] For example, when a groove 114 is provided between two adjacent conductive parts 113, the size of the first power supply conductor 131 is greater than the groove width of the groove 114, and the size of the second power supply conductor 132 is greater than the groove width of the groove 114.

[0118] In other embodiments, the size of the first power supply conductor 131 is greater than the spacing between two adjacent conductive portions 113 in the first direction X, and the size of the second power supply conductor 132 is less than or equal to the spacing between two adjacent conductive portions 113 in the first direction X; the size of the first power supply conductor 131 is less than or equal to the spacing between two adjacent conductive portions 113 in the first direction X, and the size of the second power supply conductor 132 is greater than the spacing between two adjacent conductive portions 113.

[0119] In some embodiments, the heating element 12 is positioned between the roller 20 and the mopping member 30, such that the heating element 12 is in close contact with the mopping member 30, which can better heat the mopping member 30.

[0120] In some embodiments, the first power supply conductor 131 is provided with a first conductive element 1311 extending along a first direction X, the second power supply conductor 132 is provided with a second conductive element 1321, and the power supply bracket 50 is provided with a first wire 51, a second wire 52, a first spring 53, and a second spring 54; wherein, the first end of the first wire 51 is connected to the first conductive element 1311, the second end of the first wire 51 is connected to the first spring 53, the first end of the second wire 52 is connected to the second conductive element 1321, the second end of the second wire 52 is connected to the second spring 54, and the first spring 53 and the second spring 54 respectively elastically contact the positive and negative output portions of the power supply (e.g., battery pack) on the base 200. Of course, the first spring 53 and the second spring 54 may not be provided, that is, the second ends of the first wire 51 and the second ends of the second wire 52 are respectively connected to the positive and negative output portions of the power supply (e.g., battery pack) on the base 200.

[0121] The first conductive element 1311 and the second conductive element 1321 can be conductive rods.

[0122] Please refer to Figure 7 The second aspect of this application provides a cleaning device 1, which includes a base 200 and a roller brush 100 as described in the first aspect, the roller brush 100 being mounted on the base 200. Exemplarily, the cleaning device 1 is a floor scrubber, sweeper, mop, etc.

[0123] In some embodiments, the cleaning device 1 further includes a controller and a power supply module connected to the controller, the power supply module being connected to the power supply conductor group 13; wherein the controller is used to control the power supply power of the power supply module during the startup phase to be greater than the power supply power of the power supply module during the operation phase. In this way, rapid heating of the roller brush 100 can be achieved, which is beneficial to improving cleaning efficiency.

[0124] In some embodiments, the cleaning device 1 further includes a controller and a drive unit 40 connected to the controller. The drive unit 40 is used to drive the roller brush 100 to rotate. When drying the roller brush 100, the controller controls the drive unit 40 to drive the roller brush 100 to rotate at a speed of 10-100 rpm. It should be noted that, for faster drying, the roller brush 100 can be spun dry at a high speed before drying; for example, the spin-drying speed of the roller brush 100 can be 400 rpm. During the cleaning process, the rotation speed of the roller brush 100 is 500 rpm or higher.

[0125] For example, the drive unit 40 is located inside the drum 20.

[0126] For example, the drive device 40 is a drive motor.

[0127] A third aspect of this application provides a cleaning system comprising a charging dock and a cleaning device 1 as described in the second aspect, the charging dock being used to charge the cleaning device 1.

[0128] In some embodiments, when the cleaning device 1 is placed on the charging base and the roller brush 100 is self-cleaning, the controller controls the charging base to supply power to the heating element 12. The power supply of the charging base is greater than the power supply of the cleaning device 1's own power supply (e.g., battery pack). Therefore, when the roller brush 100 is self-cleaning, the mopping part 30 of the roller brush 100 can be heated more quickly, which helps to improve cleaning efficiency.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
