[0055] refer to Figure 8 and Figure 9 The cleaning brush also includes a receiving groove 15, which is disposed on the side of the housing 1 and extends from the head 11 to the first handle 13. The cleaning brush also includes an anti-detachment component 5, which is disposed in the receiving groove 15.

[0056] refer to Figure 9The anti-detachment component 5 includes a first blocking part 51 and a second blocking part 52. The first blocking part 51 is fixedly disposed in the receiving groove 15, and the second blocking part 52 is rotatably disposed in the receiving groove 15. When the second blocking part 52 rotates to fit against the bottom surface of the receiving groove 15, the second blocking part 52 extends from the head 11 to the handle part 12. The second blocking part 52 is provided with a clearance hole 53, which is used to avoid the first blocking part 51. The second blocking part 52 is configured to abut against or separate from the first blocking part 51 to restrict or release the rotation of the handle part 12 relative to the head 11.

[0057] Specifically, the first blocking part 51 has a protrusion 54 at the end away from the brush head 2, and the protrusion 54 protrudes along the axial direction of the first handle 13 towards the first handle 13. The second blocking part 52 has a slot 55, which is connected to the clearance hole 53. When the second blocking part 52 rotates in the first direction until the top surface of the slot 55 abuts against the protrusion 54, the top surface of the slot 55 is located below the protrusion 54, which can restrict the first handle 13 from rotating circumferentially along the head 11 and prevent the threaded connection between the first handle 13 part 12 and the head 11 from loosening. When the second blocking part 52 rotates in the second direction until the top surface of the slot 55 separates from the protrusion 54, until the second blocking part 52 is perpendicular to the receiving groove 15, the restriction on the first handle 13 can be released, allowing the first handle 13 to rotate circumferentially along the head 11 and the first handle 13 and the head 11 to separate. By providing the anti-detachment component 5 and the receiving groove 15, the first handle 13 can be prevented from falling off the head 11.

[0058] In this embodiment, the first direction is clockwise and the second direction is counterclockwise.

[0059] For details, please refer to Figure 10 The cleaning brush also includes a battery 6, which is disposed in the head 11 and extends into the first handle 13. The battery 6 is electrically connected to the drive unit 3 to supply power to the drive unit 3.

[0060] Specifically, the cleaning brush also includes a charging port 7, which is located on the top surface of the head 11 and is electrically connected to the battery 6.

[0061] refer to Figure 1 , Figure 6 and Figure 8 The handle portion 12 also includes a lug 16, a connecting shaft 17, and two ear pieces 18. The lug 16 protrudes from the end of the first handle 13 away from the head 11. The two ear pieces 18 are disposed at one end of the second handle 14, and a receiving space is formed between the two ear pieces 18. The receiving space is adapted to the lug 16, and the lug 16 is inserted into the receiving space. The connecting shaft 17 passes through the two ear pieces 18 and the lug 16, thereby realizing the rotational connection between the second handle 14 and the first handle 13.

[0062] For details, please refer to Figure 6 and Figure 7 The first handle 13 has a first end face 131 and a second end face 132 at the end away from the head 11. The first end face 131 is located below the first handle 13, and the second end face 132 is located above the first handle 13. The first end face 131 is perpendicular to the axis of the first handle 13, and the second end face 132 is inclined relative to the axis of the first handle 13. A lug 16 extends from the bottom of the first end face 131 to the top of the second end face 132 to allow the second handle 14 to rotate relative to the first handle 13. The first end face 131 abuts against the lug 18, or the second end face 132 abuts against the lug 18.

[0063] In this embodiment, the second handle 14 can rotate 135 degrees around the first handle 13.

[0064] refer to Figure 3 The cleaning brush also includes a sensor, a processor, and an indicator light. The sensor is located on the drive unit 3 and is used to detect the pressure signal when the drive unit 3 is working. The sensor and the processor are electrically connected. The processor is also electrically connected to the indicator light and is used to receive the pressure signal output by the sensor and output different indication signals to the indicator light according to the pressure signal, so that the indicator light emits different colors of light according to different indication signals. The processor is also electrically connected to the drive unit 3 and is also used to control the drive unit 3 to turn off according to the pressure signal.

[0065] Specifically, the sensors and processor are all located within the head 11. (Reference) Figure 10 The head 11 also has a light-transmitting part 19, which surrounds the head 11, and the indicator light is located inside the light-transmitting part 19. By providing the light-transmitting part 19 surrounding the head 11, the light can be observed from 360 degrees, making it easy to observe.

[0066] When the cleaning brush is turned on, the user will apply different pressures to the cleaning brush in different scenarios. The sensor is used to detect the pressure signal when the drive unit 3 is working and output different pressure signals to the processor. The processor processes the different pressure signals input by the sensor and sends different indication signals to the indicator light. The indicator light displays different colors according to the different indication signals.

[0067] When using the book-handheld device, the indicator light will show green and blue when the pressure is normal and the device can be used normally. When the indicator light shows red, it is a warning that excessive force will damage the cleaning brush. You need to reduce the pressure to use it normally. If the red warning continues and the pressure is not reduced, the device will automatically shut down. Pressing the button again will restart it.

[0068] refer to Figure 3This application also provides a control circuit for a drive unit 3 with acoustic and optical feedback, which can output acoustic and optical feedback through the transmission of pressure signal when the drive unit 3 is working. At the same time, if the pressure signal exceeds a certain value, the drive unit 3 will automatically stop working.

[0069] refer to Figure 14 The circuit includes a main control chip U1, a pressure sensing circuit, an analog signal acquisition and comparison circuit, a driving circuit for the driving component 3, and an audio-visual driving circuit. The output terminal of the pressure sensing circuit is electrically connected to the first input terminal of the main control chip U1, the first output terminal of the main control chip U1 is electrically connected to the input terminal of the motor driving circuit, the output terminal of the analog signal acquisition and comparison circuit is electrically connected to the second input terminal of the main control chip U1, and the second output terminal of the main control chip U1 is electrically connected to the input terminal of the audio-visual driving circuit.

[0070] The signal Y output by the pressure sensing circuit is compared with the signal Y1 initially set by the main control chip U1 to obtain the comparison signal value δ. y =Y1-Y, thus outputting sound and light; when setting the final pressure protection parameter K, since the voltage coefficient g changes, the voltage coefficient also needs to be adjusted according to the pressing force. The pressure protection value K(g′-g) is set through the final obtained voltage coefficient g′, which controls the start and stop of the final motor drive circuit.

[0071] Specifically, the main control chip U1 is model CMS79F113.

[0072] Specifically, the cleaning brush also includes a switch 8, which is located on the top surface of the head 11 and is used to control the start of the drive unit 3.

[0073] The cleaning brush also includes a stop 9, which is disposed on the second handle 14. The stop abuts against the lug 16. The stop 9 can be pressed and moved back and forth in the vertical direction to achieve the abutment or separation of the stop 9 relative to the lug 16, thereby adjusting the angle of the first handle 13 and the second handle 14.

[0074] Furthermore, the bottom end of the lug 16 is provided with multiple abutment grooves along its circumference. When the stop member 9 locks the second handle 14, one end of the stop member 9 abuts against one of the abutment grooves to prevent the second handle 14 from rotating relative to the first handle 13. When the stop member 9 unlocks the second handle 14, one end of the stop member 9 separates from the abutment groove, and the second handle 14 can rotate relative to the first handle 13. When the stop member 9 is released, the stop member 9 can move upward and abut against another abutment groove, thereby locking the first handle 13 and the second handle 14.

[0075] This application provides a cleaning brush for cleaning the corners of pool walls and steps. It has a replaceable battery 6 and is equipped with an anti-detachment component 5. The brush head 2 is replaceable and the handle 12 is foldable, making it flexible for various cleaning environments. It is also equipped with an indicator light to show the application force, which can prevent excessive force from damaging the cleaning brush.
