Embodiment Construction

[0018] In order to transmit the drive motion of the drive shaft (which may be the motor shaft of an electric motor or may be connected to the motor shaft through an intermediate transmission element) to the plurality of mold rotors in the mold head of the personal care appliance, the drive shaft is connected to a plurality of A drive train for distributing the driving torque of a drive shaft to each of a plurality of mold rotors comprising: a crank mechanism including an input crank member having a coupling means for connection to said drive shaft; a transmission an element configured to be driven by the input crank element; and a plurality of output crank elements configured to be driven by the conveyor element to rotate about a rotor axis of the plurality of mold rotors. The die rotor may be torque-transmittingly connected to the rotating portion of the output crank member. The input crank element can transform the rotation of the drive shaft into a rotary or orbital motion,...

Abstract

The present invention relates to personal care appliances such as shavers, hair removal devices or toothbrushes having tools of the rotatory type. More particularly, the invention relates to a tool head for a personal care appliance, including a plurality of tooling rotors rotatably supported about rotor axes and a drive train for rotatorily driving said tooling rotors from a motor. The inventionalso relates to an electric shaver having a cutter head with a plurality of cutting rotors driven by a drive train connectable to a motor. The drive train may provide for an input crank element havingconnection means for connecting to a drive shaft, a transmitter element configured to be driven by said input crank element, and a plurality of output crank elements configured to be driven by said transmitter element to rotate about the rotor axes of the tool rotors and to rotatorily drive the tool rotors about said rotor axes. Said transmitter element distributes the driving action of the inputcrank element to the output crank elements, wherein said input crank element transforms the rotatory movement of the drive shaft into a revolving or orbiting movement of the transmitter element whichis again retransformed into a rotatory movement by means of the output crank elements to rotatorily drive the tooling rotors.

Description

technical field [0001] The present invention relates to personal care appliances such as razors, hair removal devices, peeling devices or toothbrushes with rotary implements. More particularly, the present invention relates to a tool head for a personal care appliance comprising a plurality of mold rotors rotatably supported about a rotor axis and a drive train for rotationally driving the mold rotors from a motor. The invention also relates to an electric razor having a cutting head with a plurality of cutting rotors driven by a drive train connectable to a motor. Background technique [0002] An electric razor may have one or more rotating cutter elements, which may be driven in an oscillating or continuous manner by an electric motor connected to the rotating cutter elements by a drive train that transmits the rotation of the motor shaft to the rotating cutter elements superior. [0003] In a cutter head with several cutting rotors, the drive movement of the motor shaft...
