Title:
IMPLEMENT FOR PERSONAL CLEANING AND CARE
Document Type and Number:
WIPO Patent Application WO/2016/119136
Kind Code:
A1
Abstract:
Provided is an implement for personal cleaning and care; a driver (110) of said implement comprises a transducer (130), a driving coil (114), a driving coil core (115), and a driver frame (112, 113). The transducer comprises a drive shaft (111), a transducer resilient-member fixing member (124), permanent magnets (116, 117) arranged on the left and right sides of the longitudinal axis of the drive shaft, permanent magnet frames (118, 119) fixedly connecting the permanent magnets, transducer actuator arms (125, 126), and transducer resilient members (122, 123). The permanent magnets (116, 117) are independent of each other; the polarity of the magnetic pole of the permanent magnet of one side and in the direction facing the driving coil (114), is S or N, and the permanent magnet of the other side has in the direction facing the driving coil (114) a polarity opposite to the polarity of the permanent magnet of said first side; the angle between the direction of the magnetic lines of force inside the permanent magnets (116, 117) and the direction of the longitudinal axis of the driving coil core (115) is greater than 45° and smaller than 135°; the permanent magnets (116, 117) may move with respect to the transducer resilient-member fixing member (124). When the current of the driving coil (114) is alternating current having a frequency of f0, the direction of movement of the permanent magnets (116, 117) is approximately parallel to the direction of the longitudinal axis of the driving coil core (115), and the angle between the two is greater than 170° and smaller than 190°. The present cleaning and care implement has a simple and compact structure and is low in cost, easy to assemble and steady in rotation; it has low damping and is safe and reliable.
