[0041] See also Figures 1 to 4 The present invention provides a cleaning brush, which can improve the cleaning efficiency by scrubbing an auxiliary brush, and can also be installed on a high-pressure cleaning machine as a cleaning accessory, which can effectively improve the problem that the speed of the existing cleaning brush is limited by the water flow rate, resulting in insufficient speed and poor cleaning effect.

[0042] See also Figure 1 and Figure 2The cleaning brush comprises: a brush handle 100, a power assembly 200, a first brush 300 and an energy assembly 400. The structure of the brush handle 100 is not limited, and includes but is not limited to a shell with a hollow chamber or a solid rod-shaped structure. In one example of the present invention, the brush handle 100 is a shell made of plastic material, and a accommodating chamber 110 is provided in the shell. An interface 102 is provided at one end of the accommodating chamber 110, through which a fluid with power can be received, such as a tap water pipe, a fluid pumped in by a suction device, or a cleaning liquid sprayed from a high-pressure cleaner; the housing of the power assembly 200 is installed in the accommodating chamber 110. The power assembly 200 may include only a motor 210, or may include a motor 210 and a reducer 220, or a combination of the motor 210 and other transmission structures. In this example, the power assembly 200 adopts a combination of a motor 210 and a reducer 220. The first brush 300 is disposed outside the housing of the brush handle 100 and is driven to rotate by the power assembly 200. A spray hole 320 is provided on the first brush 300. The spray hole 320 is fluidically connected to the interface 102 via a pipe 700 or channel. Preferably, the water outlet direction of the pipe or channel intersects the output axis of the power assembly 200. The structure and shape of the first brush 300 are not limited and can, for example, be square, star-shaped, elliptical, or any other suitable shape. The energy assembly 400 is mounted on the brush handle 100 and provides power to the power assembly 200. It should be noted that the energy assembly 400 in the present invention can be a battery pack or a fuel or gas power generation device, capable of providing sufficient power to the power assembly 200.

[0043] See also Figure 1 and Figure 2In the present invention, the first brush 300 can be mounted on the output shaft 221 in any suitable manner that can secure the first brush 300 to the output shaft 221 and connect the cleaning liquid flowing into the interface 102 to the spray hole 320. In one example of a cleaning brush according to the present invention, the first brush 300 is connected to the output shaft 221 of the power assembly 200 via a joint assembly 600, and the output axis of the power assembly 200 is coaxial with the rotation axis of the first brush 300. The joint assembly 600 drives the first brush 300 to rotate while simultaneously achieving communication between the interface 102 and the spray hole 320. The joint assembly 600 includes a base 610 and a rotating body 620. The base 610 can be secured within the accommodating cavity 110 of the brush handle 100, or secured to the housing of the power assembly 200, or simply mounted on the output shaft 221 of the power assembly 200 without being connected to the housing of the power assembly 200 or the accommodating cavity 110. A liquid inlet 614 is provided on the outer wall of the base body 610, and the liquid inlet 614 is connected to the interface 102 through a pipe 700; the rotating body 620 can be rotatably installed on the base body 610, one end of the rotating body 620 is connected to the output shaft 221, and the other end of the rotating body 620 is connected to the first brush 300; a flow channel is provided in the rotating body 620, and during the rotation of the rotating body 620, the flow channel is always connected to the liquid inlet 614 and the spray hole 320.

[0044] See also Figure 2In one example of the cleaning brush of the present invention, the base 610 includes an outer sleeve 611 and a core tube 612. The outer sleeve 611 is provided with a first through hole (not shown), which extends in the same direction as the output shaft 221. The outer wall shape and size of the core tube 612 match the shape and size of the first through hole. The core tube 612 is inserted into the first through hole. Considering that there is no relative motion between the outer sleeve 611 and the core tube 612 during normal operation, the shape of the first through hole is not limited, including but not limited to square, circular, star-shaped, elliptical, etc. The core tube 612 is provided with a second through hole (not shown), which also extends in the same direction as the output shaft 221. The outer wall shape and size of the rotating body 620 match the shape and size of the second through hole. Considering that there is rotational relative motion between the core tube 612 and the rotating body 620, the shape of the second through hole is circular or other suitable rotating body contour. The rotating body 620 is installed in the second through hole and rotates relative to the core tube 612. A dynamic seal assembly 623 is provided between the rotating body 620 and the core tube 612. The dynamic seal assembly 623 can be any suitable dynamic seal assembly 623 suitable for rotary sealing, such as a skeleton oil seal, a packing seal, etc. In one embodiment of the present invention, the dynamic seal assembly 623 includes at least two sets of packing seal assemblies. The at least two sets of packing seal assemblies are provided on the contact surface between the rotating body 620 and the core tube 612, and are respectively provided on both sides of the liquid inlet 614 to prevent the cleaning liquid in the liquid inlet 614 from leaking from the mating surfaces of the rotating body 620 and the core tube 612 on both sides.

[0045] See also Figure 2 In one example of the cleaning brush of the present invention, a boss 625 is provided on the rotating body 620 to mate with the end of the core tube 612. A first washer 630 is disposed between the end surface of the core tube 612 and the boss 625. A connector 650 is mounted on the end of the rotating body 620 facing the first brush 300. A second washer 640 is disposed between the connector 650 and the end surface of the core tube 612. The first washer 630 and the second washer 640 are made of a wear-resistant material, and the hardness of the first washer 630 and the second washer 640 is preferably less than that of the rotating body 620 and the core tube 612. This reduces wear on the core tube 612 and the rotating body 620 during their relative rotation.

[0046] See also Figure 2In the present invention, if the outer sleeve 611 and the core tube 612 are bonded or interference fit, the static sealing component 613 may not be provided. However, in order to have a better sealing effect, in an example of the cleaning brush of the present invention, a static sealing component 613 is provided between the outer sleeve 611 and the core tube 612. The static sealing component 613 can be any suitable sealing component suitable for static sealing, such as an O-ring, a sealing gasket, etc. In an example of the present invention, the static sealing component 613 includes at least two O-rings, and at least two O-rings are provided on the contact surface of the outer sleeve 611 and the core tube 612, and are respectively provided on both sides of the liquid inlet 614 to prevent the cleaning liquid in the liquid inlet 614 from leaking from the matching surfaces of the outer sleeve 611 and the core tube 612 on both sides.

[0047] See also Figure 2 To maintain a stable flow rate from the spray hole 320, in one example of the cleaning brush of the present invention, a first liquid storage chamber 624 is provided between the rotating body 620 and the core tube 612. The first liquid storage chamber 624 is disposed around the outer wall of the rotating body 620. The outer wall of the first liquid storage chamber 624 communicates with the liquid inlet 614, and the inner wall of the first liquid storage chamber 624 communicates with the flow channel within the rotating body 620. The flow channel is disposed on the rotating body 620 and includes an axial extension section 621 and a radial extension section 622. One end of the axial extension section 621 communicates with the spray hole 320, and the other end of the axial extension section 621 communicates with the radial extension section 622. The outer side of the radial extension section 622 remains in communication with the first liquid storage chamber 624 during the rotation of the rotating body 620. During the rotation of the rotating body 620, the opening of the flow channel remains in communication with the first liquid storage chamber 624, thereby ensuring a stable flow rate of cleaning liquid within the flow channel. It should be noted that the setting form of the first liquid storage chamber 624 between the rotating body 620 and the core tube 612 is not limited. For example, it can be a combination of the inner wall of the core tube 612 and the groove set on the outer wall of the rotating body 620, or it can be a combination of the outer wall of the rotating body 620 and the groove set on the inner wall of the core tube 612, or as in this example, a combination of the groove set on the outer wall of the rotating body 620 and the groove on the inner wall of the core tube 612.

[0048] See also Figure 2Taking into account the centrifugal force caused by rotation, in one example of the present invention, a second liquid storage chamber 615 is provided between the outer sleeve 611 and the core tube 612. The second liquid storage chamber 615 is arranged around the outside of the first liquid storage chamber 624. At least one connecting hole 6121 is provided between the first liquid storage chamber 624 and the second liquid storage chamber 615. The outer side of the second liquid storage chamber 615 is connected to the liquid inlet 614, and the inner side of the second liquid storage chamber 615 is connected to the first liquid storage chamber 624 through the at least one connecting hole 6121. It should be noted that the arrangement of the second liquid storage chamber 615 between the outer sleeve 611 and the core tube 612 is not limited. For example, it can be a combination of the outer wall of the core tube 612 and a groove provided on the inner wall of the outer sleeve 611, or a combination of a groove provided on the outer wall of the rotating body 620 and a groove provided on the inner wall of the core tube 612, or a combination of the inner wall of the outer sleeve 611 and a groove provided on the outer wall of the core tube 612 as in this example.

[0049] See also Figure 2 The first liquid storage chamber 624 and the second liquid storage chamber 615 of the cleaning brush of the present invention are arranged in an annular manner and connected through the connecting hole 6121. On the one hand, during the rotation of the rotating body 620, the partition wall between the first liquid storage chamber 624 and the second liquid storage chamber 615 can weaken the centrifugal force of the cleaning liquid in the first liquid storage chamber 624 caused by the rotation of the rotating body 620. On the other hand, the communication between the first liquid storage chamber 624 and the second liquid storage chamber 615 can be ensured through the connecting hole 6121, thereby fully ensuring the stability of water outflow from the spray hole 320.

[0050] See also Figure 2 In the present invention, the connection method between the first brush 300 and the joint assembly 600 can be any suitable method that can achieve a sealed connection. Taking into account the need for interchangeability and replacement, in one example of the cleaning brush of the present invention, the first brush 300 and the joint assembly 600 are detachably connected, and the cleaning brush also includes a second brush that is interchangeable with the first brush 300. The second brush can be the same as the first brush, or different from the first brush, as long as the connection part structure is the same and can be interchangeably installed on the connector 650. In one example of the present invention, the connector 650 is a quick-connect connector installed on the rotating body 620. The installation method between the quick-connect connector and the rotating body 620 includes but is not limited to welding, bonding and threaded connection. In one example of the present invention, the quick-connect connector is threadedly connected to the rotating body 620, and the first brush 300 and the joint assembly 600 are connected via a quick-connect connector. It should be noted that the quick-connect connector can be a standard quick-connect connector commonly used in the hydraulic field or pipeline connection field, which will not be described in detail here.

[0051] See also Figures 2 to 4Considering the uniformity of the cleaning liquid spraying, in an example of the cleaning brush of the present invention, the spray hole 320 is coaxially arranged with the output shaft 221. The first brush 300 is a disc brush, which includes a disc body 310 and at least one circle of bristles 330 arranged around the spray hole 320. The shape of the disc 310 includes, but is not limited to, a disc, a rectangle, or a square. Preferably, considering the dynamic balance of the rotating body 620, in one example of the cleaning brush of the present invention, the disc 310 is disc-shaped. The bristles 330 can be arranged in a variety of ways, as long as a contour surrounding the spray hole 320 is formed. For example, the bristles 330 can be arranged in a spiral pattern on the disc 310, with the spray hole 320 located at the center of the spiral. In this arrangement, when the cleaning liquid is ejected from the spray hole 320 and radially ejected, it is intercepted by the bristles 330, effectively conserving cleaning liquid. When the cleaning liquid is not merely water, for example, but contains a foaming component such as detergent, in one example of the cleaning brush of the present invention, the first brush 300 includes multiple annular rings of bristles 330, which are arranged concentrically with the spray hole 320. This arrangement not only disperses the cleaning liquid more evenly under the action of centrifugal force, resulting in better foam, but also conserves water and detergent.

[0052] However, in another example of the cleaning brush of the present invention, the second brush is a roller brush, which includes a roller and bristles installed on the cylindrical surface of the roller. The inner cavity of the roller is closed and connected to the spray hole, and a plurality of small holes are provided on the wall of the roller to allow the cleaning agent to leak to the side of the bristles.

[0053] See also Figure 1 Taking into account the environmental friendliness of energy, in an example of the cleaning brush of the present invention, the energy component 400 is installed between the power component and the gripping portion and closer to the power component. Such an installation position is more ergonomic and can increase the operating comfort of the operator. The energy component 400 includes a rechargeable battery pack and an indicator light 500. The rechargeable battery pack is detachably mounted on the brush handle 100. The brush handle 100 is provided with a Type C charging port 101 for charging the battery pack, and the battery pack can be charged according to the power level. In an example of the cleaning brush of the present invention, the cleaning brush also includes an indicator light 500 and a switch. The indicator light 500 is exposed outside the brush handle 100 and is used to display the battery power status. The switch is provided on the gripping portion of the brush handle 100 and can turn the cleaning brush on or off.

[0054] Considering the need for automated control, in one example of the cleaning brush of the present invention, the cleaning brush further includes a controller (not shown), which is electrically connected to the power assembly 200 and the energy assembly 400. The controller can be used to set different speed modes, such as high speed, medium speed, low speed, or forward and reverse rotation, to provide targeted cleaning for different stains and objects to be cleaned.

[0055] See also Figure 1 For ease of use, in one example of the cleaning brush of the present invention, the brush handle 100 extends in an arm-like configuration with a bend at one end. The first brush 300 is mounted on the bend, and the interface 102 is located at the other end of the brush handle 100. The portion of the brush handle 100 near the interface 102 forms the grip, with the longitudinal axis of the grip intersecting the output axis of the power assembly 200. This arrangement is both convenient for operation and ergonomically sound. The arm-like extension makes it easier to reach distant stains, and the bend facilitates application of force to the surface being cleaned.

[0056] The present invention also provides a cleaning system, which includes a cleaning device and a cleaning brush as described in any of the above examples. The cleaning device in the cleaning system of the present invention can be any suitable device in the prior art that can provide a powered cleaning fluid, including but not limited to a high-pressure cleaner. In one example of the present invention, the cleaning device includes a pump and an outlet pipe. The pump provides power for the fluid to flow and transports the fluid to the outlet pipe; the cleaning brush includes a brush handle, which is provided with an interface, which is connected to the outlet pipe and receives the cleaning fluid flowing in from the outlet pipe; the power component is installed on the brush handle; the brush is driven to rotate by the power component, and the brush is provided with a spray hole, which is connected to the interface fluid; the energy component is installed on the brush handle and supplies energy to the power component.

[0057] When the cleaning brush of the present invention is in use, the interface on the brush handle is used to receive fluid, and the fluid is an external power fluid, such as a cleaning device such as a high-pressure washer or an external water source such as tap water, which can improve the cleaning efficiency by assisting in scrubbing. At the same time, the cleaning brush of the present invention can be installed on a cleaning device or a cleaning device as a cleaning accessory, which can not only efficiently clean the surface of a car, the ground and other outdoor objects that need to be cleaned, but also can improve the problem that the rotation speed of the existing cleaning brush is limited by the water flow rate, the speed is not enough, and the cleaning effect is poor. In addition, the present invention can pass cleaning liquid into the interface of the cleaning brush. During the cleaning process, the brush rotates, which will make the detergent foam rich, provide a good cleaning experience, and also save more detergent. Therefore, the present invention effectively overcomes some practical problems in the prior art and thus has high utilization value and use significance.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
