Description

Technical Field

[0001] This utility model relates to the field of cleaning appliances, specifically to a multifunctional cleaning brush. Background Technology

[0002] Existing brushes can only be used by hand to scrub back and forth, and can only clean one side at a time. For some winter clothes, which are washed less frequently, the collar, hem, cuffs and other areas are often more time-consuming and laborious to clean, requiring multiple scrubbing and turning. When encountering narrow spaces such as zippers and the inside of cuffs, the back-and-forth scrubbing motion of traditional brushes is even more difficult to exert its scrubbing ability. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a multi-functional cleaning brush with excellent cleaning effect and multiple functions.

[0004] To address the above problems, the following technical solution is provided: A multifunctional cleaning brush includes a housing, an electrical compartment, a drive board, a control board, and a rechargeable battery electrically connected to the drive board; the electrical compartment also includes two sets of drive mechanisms electrically connected to the drive board, each drive mechanism including a motor and a gearbox, the output shafts of the two drive mechanisms extending out of the front end of the housing being parallel to each other and spaced apart; it also includes roller brushes located on each output shaft, each roller brush including a brush shaft and bristles arranged radially on the outer wall of the brush shaft; the two drive mechanisms are controlled by the drive board to make their output shafts rotate in the same direction or in opposite directions.

[0005] The present invention is further provided in that the front end of the housing is provided with a protective sleeve surrounding the two roller brushes, and the end of the protective sleeve away from the housing is open; the protective sleeve is provided with an inlet groove that is through to the two roller brushes at the position between the two roller brushes.

[0006] The present invention is further provided that the end of the protective sleeve away from the shell is provided with a guide rounded corner at the junction with the inlet groove.

[0007] The present invention is further configured such that the cross-section of the casing is racetrack shaped.

[0008] The present invention is further provided with a motor sealing ring at the position where the output shaft passes through the housing.

[0009] The present invention is further configured such that the roller brush is detachably arranged relative to the output shaft; when the two roller brushes rotate, the ends of their bristles are spaced apart, tangent to each other, or intersecting.

[0010] The present invention is further configured such that the drive board is provided with a charging port, the charging port is exposed through the housing and is provided with a port sealing ring.

[0011] The present invention is further configured such that the housing includes a head and a tail; the drive mechanism is located in the electrical compartment of the head; and the drive plate and the rechargeable battery are located in the electrical compartment of the tail of the housing.

[0012] The present invention is further configured such that the control board is located inside the electrical compartment at the head of the housing; the control board is provided with a mode control switch and a working indicator light; the outer wall of the head of the housing is provided with a display window, and a panel cover is provided outside the display window; the mode control switch and the working indicator light are located below the panel cover.

[0013] The present invention is further configured such that the panel cover has a counter-rotating window and a co-rotating window, and the mode control switch and the working indicator light are both in two sets, respectively located below the counter-rotating window and the co-rotating window; the mode control switch is a touch switch, and the resistance spring wires of the two touch switches abut against the bottom of the counter-rotating window and the co-rotating window respectively; the working indicator lights are all located in the central area of ​​the resistance spring wires.

[0014] The beneficial effects of this utility model are: 1. During washing, the corners of the garment can be placed between adjacent roller brushes, and the rolling of the roller brushes replaces the traditional reciprocating brushing, greatly improving washing efficiency. It can also be used for washing while immersed in water (when the brush is immersed in water, the reciprocating motion can easily cause water to splash). During washing, simply move the housing slowly. It has high washing efficiency and is suitable for various narrow areas (such as the inside and outside of cuffs). The two roller brushes rotate in the same direction, which is suitable for larger garments that are not easily moved by the friction of the roller brushes. The two roller brushes rotate in opposite directions, which is suitable for smaller / lighter items (such as shoelaces). The opposite rotation can cancel out the crushing and pushing forces of the two rollers on the front and back surfaces of the item being washed, preventing the item from shifting due to the two rollers crushing each other. 2. The protective sleeve protects the non-working area of ​​the roller brush and prevents accidental entanglement of hair, thread, or other items; the end of the protective sleeve away from the housing is open for easy replacement of the roller brush; the clothes to be washed are placed between adjacent roller brushes through the inlet groove. 3. The rounded corners can reduce scratches when the clothes being washed are inserted, and also improve the smoothness of insertion (for example, when cotton clothes are wet and the air inside is difficult to expel and they are in a state of expansion, the rounded corners can effectively restrain them). 4. When the two roller brushes rotate, the bristle tips are spaced apart, which is suitable for brushing thicker clothes; when they are tangent to each other, which is suitable for brushing thinner clothes; when they intersect, which is suitable for some areas with stubborn stains that need to be scrubbed vigorously using the elasticity of the bristles. 5. When the indicator light below the rotating window is lit, the output shafts of the two drive mechanisms rotate in opposite directions; when the indicator light below the rotating window is lit, the output shafts of the two drive mechanisms rotate in the same direction; the touch switch is integrated with the indicator light, and the indicator light is lit when touched.
