Description

FIELD OF THE INVENTION

The present disclosure relates to the technical field of cleaning brushes. More particularly an electric cleaning device

BACKGROUND OF THE INVENTION

Currently, many customers usually use electric cleaning devices to achieve an automotive clean effect, for example, electric toothbrushes, cleaning brushes, facial cleaners, etc. For facial cleaners, it mainly includes a brush vibrating type cleaning device and a brush rotating type cleaning device. The cleaning brush generally uses a rotating brush or a manual brush. For an electric toothbrush, a linkage structure is generally used to drive the brush head to move back and forth, or a vibrating manner is used to make the brush head vibrate.

For example, the Chinese patent CN210353688U discloses a magnetic-attraction type cleaning brush head and a face cleaner and specifically discloses that the face cleaner comprises a core assembly and the described magnetic-attraction type cleaning brush head provided on the core assembly. The core assembly comprises a base, a motor, and a gear assembly which are arranged in the base, an output shaft is rotatably arranged on the base, and the motor drives the output shaft to rotate via the gear assembly. The technical solution disclosed in the patent uses on a motor to drive a brush head to rotate. However, in the rotating process of the brush head, the linear velocities at different positions of the brush head are different, and the closer to the rotational axis, the smaller the linear velocity is; therefore, when facial skin is cleaned by the rotation of the brush head, the problem of uneven cleaning force exists, resulting in inconsistent cleaning degrees.

For another example, Chinese patent CN21987807U discloses a facial cleaner, which includes a housing, an acoustic wave motor, an ultrasonic transducer, a fixing frame, and a brush head. The acoustic wave motor is fixedly connected to the fixing frame, the ultrasonic transducer is arranged on the fixing frame in a threaded manner, and the brush head is detachably arranged on the fixing frame, the acoustic wave motor drives the brush head to swing back and forth so as to clean a face. By arranging the acoustic wave motor and the rubber brush head at the head part of the facial cleaner, the brush head can swing back and forth under the drive of the acoustic wave motor, and at the same time, a slight vibration can be generated to form back and forth wiping on the face part. When the skin is cleaned using the brush head vibration, since the brush displacement amplitude is small due to the vibration, the cleaning efficiency will be reduced.
