Definitions

• the present invention discloses a hair treatment device comprising a mechanism for rotating said device that triggers on a given manual pulse around the axis of rotation of the handle of said device without requiring contact with the hair.
• Hairdressing devices using rotation about an axis are well known to those skilled in the art. This is for example various forms of hairbrushes such as rotating brushes with or without a blower, winders hair curlers or curling irons.
• All these devices are provided with switches for acting on the direction and sometimes the speed of rotation by keeping the switch pressed in the desired direction of rotation.
• These switches are quite easy to use for the hairdresser who can move around the person to be styled while for the individual user who does not have the same angle of view on the device, its use is often counter-intuitive, especially when both hands are occupied during a hairdressing operation.
• EP 2 365 764 A1 discloses a hairstyling device that can be driven by a motorized rotational movement given by the pulse on the handle of the device.
• the mechanism disclosed in this document uses a pull on the hair as a pulse to determine the direction of rotation. It is the resistance offered by the lock of hair that triggers the rotation mechanism of the hairdressing device.
• the detection detects the movement of the device along the lock of hair such as starting from the root to the end of a lock of hair and triggers the rotation of the device in the opposite direction.
• This device is not equipped with an angular accelerometer but with a tensile force detector. Goals of the invention
• the present invention discloses a hairstyling device that can be rotated about the axis of its handle on a single pulse given by the hand in the desired direction of rotation without any need for support or contact on a lock of hair.
• the present invention discloses a hairstyling device comprising a motorized rotary portion controlled by an angular accelerometer located in said handle, said accelerometer detecting, in use, the rotational pulses given around the longitudinal axis of said handle and transmitting a signal to start the engine in the desired direction.
• the accelerometer can be activated and deactivated by a switch located on the handle;
• the accelerometer comprises:
• an emitter and a pair of sensors connected to an electronic circuit comprising a microcontroller detecting, in use, the angle of rotation of the flywheel with respect to said sensors;
• said microcontroller having, in use, the signals between the transmitter and the sensors and detecting the direction of rotation during a user-given pulse on the handle in a desired direction of rotation, and transmitting an engine start signal in the desired direction if the angle of rotation generated by the pulse is greater than a preprogrammed angle; said motor is located in the rotating portion of said hairdressing device;
• the hairdressing device is a rotating brush, preferably a rotating fan brush or a curler winder.
• FIG. 1 represents an angular accelerometer represented in three dimensions with its emitter and its sensors.
• Figure 2 shows a detailed three-dimensional view of an angular accelerometer with its transmitter and its sensors.
• Figure 3 shows a front view perpendicular to the axis of rotation of the flywheel of the accelerometer. Possible equilibrium means are optional and are not represented in the first three figures.
• FIG. 4 represents a non-contact electromagnetic tripping and FIG. 5 a purely mechanical contact tripping.
• Figure 6 shows a first hairdressing device according to the invention in the form of a rotating blower brush comprising an angular accelerometer.
• the big black arrow represents the impulse that can be given to the handle to turn the brush.
• Figure 7 shows a second hairdressing device according to the invention in the form of winder rollers having an angular accelerometer.
• the big black arrow represents the impulse that can be given to the handle to turn the brush.
• Figure 8 is a schematic representation of the pulse detection electronic circuit given on the handle of the hairdressing device.
• FIG. 9 is a detailed representation of the circuit according to an embodiment of the invention comprising LEDs emitting light through a flywheel provided with holes in the periphery.
• This detection mechanism is mounted on the product as a direction of rotation detector.
• the internal microcontroller counts the number of holes that pass between the transceiver and also detects the direction of rotation thanks to the pair of sensors. If the angle generated by the wrist movement is greater than a preprogrammed angle, the microcontroller will generate a signal to start the motor in the proper direction. In this mode of execution, the device stops as soon as the user releases the button.
• the present invention discloses a hairdressing device requiring rotation such as for example a rotating blower brush 9 or curlers winder 10.
• a hairdressing device requiring rotation such as for example a rotating blower brush 9 or curlers winder 10.
• Such a device is always equipped with a motor generally located in the handle 7 although it may be advantageous for space problems to place it in the rotary cylinder of the hairdressing device.
• the handle is conventionally provided with a two-way switch for acting on the direction of rotation of the rotary cylinder.
• a two-way switch for acting on the direction of rotation of the rotary cylinder.
• the present invention overcomes this situation by replacing the two-way switch with a simple switch type "on / off" 13 to activate or deactivate an angular accelerometer 1 allowing a simple pulse of the wrist in the direction of rotation desired to trigger the motor in the direction of rotation desired by the user. To do this, the user does not need to look at the handle 7 but simply gives, and intuitively, a pulse in the desired direction. To disable the rotation of the cylinder, the user actuates the switch again.
• Angular accelerometers or gyrometers are well known to those skilled in the art and generally operate on a principle of inertia only or with a restoring force towards equilibrium.
• Figures 1 to 5 show various accelerometers all based on the same principle.
• the axis of the handle 7 of the hairdressing device comprises generally a component parallel to the ground, an element accentuating the effect of gravity on the flywheel 2 as an eccentric mass 14 on the flywheel 2 can be beneficial.
• the detection system of the direction of the pulse given to the handle 7 comprises in addition to the accelerometer a microcontroller measuring the direction and the amplitude of the rotation of the flywheel 2 by means of a or more transmitters 5 and sensors 4.
• the electronic circuit supporting this detection system is shown in FIGS. 8 and 9.
