    摘要： The toothbrush includes a handle portion which includes a power drive system (14) and further includes a brushhead assembly (20), which includes a brushhead arm having a brush element (21) at a distal end thereof A drive train assembly (12) is responsive to a drive signal from the power assembly for converting the action of the power assembly to a motion of the brushhead assembly. A magnet (30) is secured to the rear of the drive train, with a Hall effect sensor (32) mounted within the magnetic field produced by the magnet as the toothbrush moves in operation. Pressure on the brush element produces a phase shift of the Hall sensor output. A processor (15) determines the value of the phase shift of the Hall sensor signal as pressure is applied to the brush member and produces a signal indicative of the pressure applied by using stored information (71) which relates phase shift to pressure for the particular appliance.

    摘要： A spring mechanism for an electromagnetic drive unit converts or translates the movement and/or actuation of the electromagnet into a desired movement of the workpiece and enables simple and efficient tuning of the workpiece movement. The spring mechanism includes a housing, a spring connected to the housing, wherein at least two sections of the spring are movable with respect to the housing, a drive shaft that includes a first end having a magnet and a second end for attachment to a workpiece, and at least two tuning elements connecting the drive shaft to the movable portion of the spring. At least one of the tuning elements is adjustable. In one embodiment, the spring may be a flat spring, and the movable sections may each be positioned between a pair of cutouts defined in the spring.

    摘要： The invention relates to a teeth cleaning device for simultaneously cleaning multiple teeth, preferably all of the teeth, of a user, comprising the following: a) a mouth insert (10) for inserting into the mouth of the user; b) a plurality of cleaning structures (14) which are attached to the mouth insert (10) or are integrally formed together with the mouth insert (10), c) a coupling element (16; 16A, 16B) which is attached to the mouth insert (10); and d) a drive device (18) comprising the following: - a vibration motor (20; 20A, 20B), which can be connected to the coupling element (16; 16A, 16B) such that the vibration motor vibrates the mouth insert (10; 10A, 10B) during the operation of the teeth cleaning device, and - a cleaning program selection element (26) for selecting a cleaning program that defines a vibration frequency of the vibration motor (20; 20A, 20B) within a specified frequency range and/or a vibration amplitude of the vibration motor (20; 20A, 20B) within a specified amplitude range. The invention further relates to a method for producing such a teeth cleaning device.

    摘要： The invention relates to a brush head (100, 200) for an acoustic toothbrush, comprising a brush neck (110, 210). Said brush neck (110, 210) comprises, in a distal area, a cleaning element (130, 230) with an alignment axis (131, 231), in particular several filaments for cleaning teeth. The brush neck (110, 210) also comprises, in a proximal area, an adapter (120, 220) with an adapter axis (121, 221) for coupling to the brush head (100, 200) with a vibration generator (300) and for transmitting vibrations from the vibration generator (300) to the cleaning element (130, 230). The adapter axis (121, 221) forms with the alignment axis (131, 231) an angle greater than 90°, preferably an angle of between 91° - 120°, especially an angle of between 95° - 105°, in particularly preferably an angle of between 98° - 102°.
