Fixing structure for use in driver apparatus of electric cleaning appliance

A fixing structure for use in a driver apparatus of an electric cleaning appliance, the electric cleaning appliance comprises a handle housing (7) and a driver apparatus placed inside the handle housing (7), the driver apparatus comprises a transducer assembly and a drive coil assembly, the transducer assembly comprises a transducer, a transducer frame and a transducer assembly fixing part, the drive coil assembly comprises a drive coil, a drive coil frame and a drive coil assembly fixing part, the transducer (1) comprises a transducer drive shaft (11) inserted into a cleaning assembly, at least one transducer elastic member (15), at least one transducer elastic member fixing member (14) for fastening the transducer elastic member (15) and at least two permanent magnets (18, 19), the polarities of the magnetic poles of the permanent magnets (18, 19) in a direction toward the drive coil (6) are opposite, the permanent magnets (18, 19) are movable either relative to the transducer elastic member fixing member (14) or relative to the drive coil (6), and when an alternating current with a frequency of f0 passes through the drive coil (6), an electromagnetic force generated between the permanent magnets (18, 19) and the drive coil (6) drives the transducer (1) to resonate,

• wherein the transducer frame comprises a transducer left frame (2) and a transducer right frame (3) which are disposed separately from each other, the transducer (1) is fixedly connected with the transducer left frame (2) and the transducer right frame (3), the drive coil frame comprises a drive coil left frame (4) and a drive coil right frame (5) which are disposed separately from each other, the drive coil (6) is fixedly connected with the drive coil left frame (4) and the drive coil right frame (5), on the drive coil left frame (4) and the drive coil right frame (5) are respectively arranged a drive coil left frame hollow area (44) and a drive coil right frame hollow area (54), the drive coil left frame hollow area (44) and the drive coil right frame hollow area (54) allow a moving component in the transducer (1) to rotate back and forth without interference around the longitudinal axis (L1) of the transducer drive shaft or a straight line approximately parallel to the longitudinal axis (L1) of the transducer drive shaft in the drive coil assembly;
• wherein the handle housing (7) is fastened with the transducer assembly via a first structural feature part in a way that one is not movable relative to the other, the handle housing (7) is fastened with the drive coil assembly via a second structural feature part in a way that one is not movable relative to the other;
• and wherein the transducer assembly and the drive coil assembly are connected via a third structural feature part in a way that one is movable relative to the other, in contact facing each other or separately.
