Embodiment Construction

[0110] Hereinafter, an electric toothbrush is taken as a typical example of a personal cleaning and care appliance, and an exemplary embodiment of the present invention is described in more detail with reference to the accompanying drawings. Although the following only uses an electric toothbrush as an example for explanation, the present invention is not limited thereto. The present invention is also applicable to appliances for personal cleaning and care such as electric shavers, electric facial cleansers, and electric showers.

[0111] Like reference numerals refer to like parts throughout the drawings.

[0112] For the sake of clarity, words such as "upper", "lower", "upper", "lower", "left", "right", "horizontal", "forward", "Reverse" etc. to simply describe the interrelationship of one element or feature with another element(s) or feature(s) as shown, where the drive coil longitudinal axis direction is parallel to The direction of the magnetic field lines generated ins...

Abstract

The invention discloses a personal cleaning and care appliance. The appliance comprises a driver transducer, a drive coil, the drive coil core, drive bracket. Transducer includes a drive shaft, a transducer elastic fixing member disposed about the longitudinal axis of the drive shaft in the left and right sides of the permanent magnet, a permanent magnet fixedly connected permanent magnet bracket, transducer actuator arms and transducers elastic member. Independently of the permanent magnet, the permanent magnet pole side, the other side of the permanent magnet having a magnetic polarity opposite to the example of the permanent magnet facing the driving coil in a direction of the magnetic pole N or S polarity in the direction toward the drive coil electrode of the angle between the direction of the magnetic field lines inside the permanent magnet and the driving coil core longitudinal axis is greater than 45 degrees and less than 135 degrees, the permanent magnet relative to the transducer to move the elastic member fixing member. When the drive frequency of the coil by an alternating current, the direction of movement of the permanent magnet and the driving coil core approximately parallel to the longitudinal axis, the angle between the two is greater than 170 degrees and less than 190 degrees. The appliance has simple structure, low cost, easy assembly, smooth rotation, low noise, low damping and secure.

Description

technical field [0001] The present invention relates to an appliance for personal cleaning and care, more specifically, to personal cleaning and care appliances such as electric toothbrushes, electric razors, electric facial cleansers, electric showers and the like. Background technique [0002] For personal care appliances such as electric toothbrushes, electric shavers, electric facial cleansers, electric showers, etc., it is important to have a personal care appliance that converts the reciprocating motion into the desired rotational motion of the cleaning elements, These personal cleaning and care appliances should be simple in structure, easy to assemble, long in service life and safe and reliable. [0003] A number of drive arrangements for driving cleaning elements are known. Examples include motors, magnetic systems, and electromagnetic systems. Some drive structures use bearings (such as ball bearings) to support the driver. This structure is expensive and complic...
