[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-6 As shown, an electric cleaning brush 100 includes a housing 1, in which a mounting bracket 2 is fixedly mounted. A waterproof sealing ring 3 is provided at the mating position between the housing 1 and the mounting bracket 2, thereby forming a hollow mounting cavity within the housing 1. A control board 4 and a drive motor 5 are fixedly mounted on the mounting bracket 2, and the drive motor 5 is used to drive the transmission mechanism. The drive motor 5 is electrically connected to the control board 4. A rotating shaft 6 is mounted on the output end of the drive motor 5, and a spiral groove 61 is provided on the outer wall of the rotating shaft 6. The drive motor 5 can drive the rotating shaft 6 to rotate, thereby driving the spiral groove 61 to rotate. A guide block 7 is provided on the mounting bracket 2. The guide block 7 can slide relative to the mounting bracket 2 and is limitedly connected to the mounting bracket 2. A brush head is fixedly mounted on the guide block 7. The brush head includes a brush rod 8 and bristles 81. One end of the brush rod 8 extends out of the housing 1, and the end surface of the brush rod 8 extending out of the housing 1 is mounted with bristles 81. A radial pin 71 is provided on the guide block 7 , one end of the radial pin 71 extends into the spiral groove 61 , and the radial pin 71 can slide in the spiral groove 61 , thereby driving the brush rod 8 to extend into or out of the housing 1 .

[0024] When using the electric cleaning brush 100, the control panel 4 controls the driving motor 5 to work, thereby driving the rotating shaft 6 to rotate, driving the spiral groove 61 to rotate together; during the rotation of the spiral groove 61, the radial pin 71 will be pushed to slide in the spiral groove 61, thereby driving the guide block 7 and the brush rod 8 to reciprocate in the direction close to the shell 1 and the direction away from the shell 1, and the bristles 81 are used to wipe the area that needs to be cleaned back and forth.

[0025] The electric cleaning brush 100 can drive the brush rod 8 to reciprocate, so that it can simulate the cleaning method of manually pulling the brush rod 8 when working, meeting the operation requirements of some very narrow gaps, improving practicality, saving labor, and thus improving efficiency.

[0026] The brush head is a strip or flat brush head, capable of inserting into narrow gaps for cleaning. The bristles 81 are longer in the longitudinal direction than in the perpendicular direction. It is understood that the bristles 81 and the brush rod 8 can be integrally formed or detachable. The brush rod 8 and the transmission mechanism can also be integrally formed or detachable.

[0027] Specifically, the spiral groove 61 includes a plurality of first spirals 611 and second spirals 612 arranged in opposite directions in an interlaced manner, and the two ends of the first spiral 611 and the second spiral 612 are connected respectively. The number of the first spiral 611 and the second spiral 612 can be two, one first spiral 611 and one second spiral 612 are connected to form a roughly V-shaped chute, and the two first spirals 611 and the two second spirals 612 are roughly W-shaped chute. Taking the two first spirals 611 and the two spirals 612 as an example, in the initial state, the radial pin 71 extends into one end of the first first spiral 611 to control the operation of the drive motor 5 so that the rotating shaft 6 drives the spiral groove 61 to rotate. The first spiral 611 will push the radial pin 71 to slide on the first spiral 611, so that the brush rod 8 extends toward the side away from the housing 1; when the radial pin 71 slides to the other end of the first spiral 611, it will automatically slide into the first second spiral 612, and then the drive motor 5 continues to drive the rotating shaft 6 to rotate. The second spiral 612 pushes the radial pin 71 to slide on the second spiral 612, causing the brush rod 8 to continue extending away from the housing 1 until the radial pin 71 reaches the end of the second spiral 612 closest to the brush rod 8, at which point it reaches its maximum extension. The rotating shaft 6 continues to rotate the spiral groove 61, causing the radial pin 71 to slide from the second second spiral 612 back onto the first first spiral 611. During this process, the brush rod 8 retracts toward the housing 1. This repeated process causes the brush rod 8 to achieve reciprocating motion.

[0028] In order to limit and guide the movement direction of the guide block 7, a guide sleeve 9 is fixedly mounted on the mounting bracket 2. The guide sleeve 9 is sleeved on the periphery of the rotating shaft 6, and the guide block 7 is sleeved on the periphery of the guide sleeve 9 and is slidably engaged with the guide sleeve 9. The guide sleeve 9 has axially distributed avoidance notches 91, and the radial pins 71 pass through the avoidance notches 91 and extend into the spiral groove 61. When the drive motor 5 is operating, the radial pins 71 slide in the spiral groove 61, thereby driving the guide block 7 to slide on the guide sleeve 9. The cooperation between the guide sleeve 9 and the guide block 7 limits and guides the movement direction of the brush rod 8, thereby improving the stability of the transmission and the accuracy of the control.

[0029] To prevent the guide block 7 from rotating, at least one anti-rotation flat surface 92 is provided on the outer sidewall of the guide sleeve 9. A limiting surface 72 is provided on the inner sidewall of the guide block 7, which mates with the anti-rotation flat surface 92. The anti-rotation flat surface 92 slidably engages with the limiting surface 72. When the drive motor 5 is operating, the limiting surface 72 slides on the anti-rotation flat surface 92. The cooperation between the limiting surface 72 and the anti-rotation flat surface 92 prevents the guide block 7 from rotating with the rotating shaft 6, thereby improving transmission stability.

[0030] In this embodiment, the cross-section of the guide sleeve 9 is hexagonal, and the inner hole shape of the guide block 7 is adapted to the shape of the guide sleeve 9. In other embodiments, the guide sleeve 9 may also be in other shapes, such as triangle, rectangle, etc.

[0031] A battery 10 is fixedly mounted on the mounting bracket 2 , and the battery 10 is electrically connected to the control board 4 . The battery 10 is used to power the electric cleaning brush, and outputs current to the control board 4 through the battery 10 , so that the control board 4 can control the operation of the drive motor 5 .

[0032] A control switch 11 is provided at the end of the housing 1 and is electrically connected to the control board 4. The control switch 11 is used to control the operation or shutdown of the reciprocating electric cleaning brush and can also be used to adjust the speed of the drive motor 5; the specific function of the control switch 11 is not limited by the present invention.

[0033] A charging connector 12 is fixedly mounted within the housing 1. One end of the charging connector 12 extends out of the housing 1 and is electrically connected to the control board 4. The charging connector 12 is used to connect to an external power source to charge the battery 10, thereby extending the service life of the reciprocating electric cleaning brush. In this embodiment, the charging connector 12 is a Type-C connector; in other embodiments, any existing connector structure capable of charging, or wireless charging, may be used.

[0034] A sealing cover 13 is provided on the housing 1 at a position corresponding to the charging connector 12. This sealing cover 13 is detachably connected to the housing 1. This seal blocks the charging connector 12, preventing moisture, dust, and other particles from entering the housing 1 and enhancing the protective properties of the reciprocating electric cleaning brush. Normally, the sealing cover 13 blocks the charging connector 12. To charge, the battery 10 is reconnected to an external power source via the charging connector 12. Once charging is complete, the sealing cover 13 is replaced on the charging connector 12.

[0035] For ease of operation, a handle 14 is provided on the outer wall of the housing 1. The handle 14 facilitates manual gripping of the reciprocating electric cleaning brush for cleaning, thereby enhancing practicality. In other embodiments, the handle 14 may also be provided with an anti-slip structure such as an anti-slip strip; an extension rod may also be added to facilitate cleaning at the distal end.

[0036] The working principle of this embodiment is introduced below.

[0037] To use the electric cleaning brush for cleaning, the operator grasps the handle 14 and presses the control switch 11. The control switch 11 sends a start signal to the control panel 4, which in turn controls the drive motor 5. The drive motor 5 rotates the rotary shaft 6, which in turn rotates the spiral groove 61. The spiral groove 61 pushes the radial pin 71 to slide within the groove, which in turn drives the guide block 7 to slide on the guide sleeve 9. The guide block 7 drives the brush rod 8 to extend or retract into the housing 1, achieving linear reciprocating motion. The bristles 81 repeatedly wipe the items to be cleaned, achieving the desired cleaning effect.

However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
