As seen in Figure 1, according to cosmetic applicator 100 of the present disclosure comprise handle 102, be arranged on the handle 102 or among driver 104 and be connected to function head 106 on the driver 104.According to the disclosure, application device 100 comprises that also torque limiter 108 is used for the moment of torsion that restricted passage function head 106 (integrally or partly and at least in some cases) applies, so that moment of torsion is no more than the predetermined moment of torsion that allows.

At all or only under some running status, driver 104 can be suitable for the rotating speed that mascara is administered to cutin fiber is moved function head 106 (integrally or partly).That is to say, under some running status, driver 104 can break away from and/or separate with function head 106, make function head 106 not rotatablely move or have limited rotatablely moving (perhaps do not move or have limited motion) with respect to handle 102, simultaneously under other state, then driver 104 can be engaged and/or is connected on the head 106 so that head 106 moves with respect to handle 102 and has a component of rotatablely moving.Alternatively, but under some running status fixed drive 104 and/or head 106 rotatablely move at least preventing.For this type of alternative embodiment, driver 104 or head 106 can not take place relative rotatablely move or limited relative rotary motion (perhaps do not move or have only limited motion) only takes place between head 106 and handle 102 by driver or head 106 firmly being connected to the element (for example switch) on the handle 102 and integrally or partly engaging, making.

As for the speed of service that head 106 may adopt, can adopt approximate 1 to 200rpm speed.According to some embodiment, can adopt approximate 5 to 100rpm speed.In fact, according to particular, can adopt the speed in approximate 10 to 60rpm scopes.Speed can be fixing, perhaps can be adjustable in proper range, and as following described in more detail.

Driver 104 can comprise motor or actuator 120.Motor 120 can be has the elastic component of being, for example the mechanical motor in the potential mechanical energy source of spring or rubber belt form.Alternatively, motor 120 can be electro-motor.In this case, driver 104 can comprise that also the power supply 124 (for example battery) that is connected on the motor 120 is to provide required voltage and current.At motor 120 is the occasion of electro-motor, voltage and current even can provide by the power supply of handle 102 outsides, and for example wherein motor 120 is connected to embodiment on the power bus by for example supply socket.According to some embodiment, drive circuit can be connected to the operation of controlling motor 120 on motor 120 and the power supply 124.Drive circuit can comprise that switch 128 comes switch motor 120 or makes motor 120 be connected or separate with power supply 124.
