Description

FIELD OF THE INVENTION

The present invention relates to hair grooming appliances and more particularly to blow-dry round hair brush having a light source.

BACKGROUND

Blow-drying is a common procedure performed by hairdressers, using a blow dryer and a round hair brush, such as hair brush 100 depicted in FIG. 1. Beginning at the roots, the hairdresser gently pulls the brush through the hair to the ends while blow-drying it.

The brush that comes in contact with many clients' heads must be sterilized between uses.

Various hair-brush sterilizers are in use, such as Hair Salon UV Tool Sterilizer H6501, available from Xinhui Mingzhuo Salon & Beauty Parlor Ambience Co., Ltd., China.

These sterilizers are stand-alone receptacles into which the brushes are inserted and which sterilize the brushes using UV light or other sterilizing agents.

While in the sterilizer, the brush is not available for use by the hairdresser, which sometimes leads to less meticulous use of the sterilizer, namely the brush is not being sterilized following each use session.

In operation, the hairdresser performing blow-drying pulls the brush through the hair and aims the blow-dryer at the brush. The air current from the blow-dryer impinges on the propeller(s) blades, causing them to rotate. The rotation is transferred to the respective electric generator(s) which transform the mechanical power into electric power, which is transferred by the generator(s) to the LED/LEDs, causing them to lighten up.

FIG. 7 is a schematic representation of another embodiment of the device according to the present invention. The device of FIG. 7 is similar to the device of FIG. 3, except that the power driving the LEDs is not generated by a propeller-driven electric generator, but rather by a battery 710 mounted in the hair brush handle 220 and operated by a switch 720. The switch 720 may be installed on the far end of handle 220, as depicted in FIG. 7, or at any other suitable location. The battery 710 may be a rechargeable battery.

FIGS. 8A through 8E show a schematic representation of yet another embodiment of the device according to the present invention.

The device 800 comprises a round brush body 810 and a handle 820. The handle 820 comprises a motor 830, rotatably connected to a central shaft in the body 810 (not shown) and a battery 855 for supplying voltage to the motor 830 and to the LED/LEDs 875, as explained above in conjunction with FIG. 7 and as shown in FIG. 8D. The battery 855 may be a rechargeable battery and charging contacts 840 may be mounted on the distal end of the handle 820. The central shaft of the brush may be connected with a planetary gear (not shown) which reduces the motor speed and provides a greater moment to the brush body.

A LED/LEDs On/Off button 850 may be mounted on the handle 820.

An On/Off button 860 may be mounted on the handle 820, for controlling the motor 830 operation. With each push of the On/Off button 860 the motor performs an up to 360 degrees rotation, left or right, where the rotation degree and direction is predefined, causing the brush body 810 to rotate accordingly. The rotation is controlled by an electronic circuit. In a preferred embodiment, each rotation is predefined to 180 degrees, to best simulate a hairdresser's manual rotation of the brush.

The automatic controlled rotation of the brush has a number of advantages:

• • Prevents joint diseases typical to hairdressers;
  • Stable and repeated rotation regardless of the hairdresser's state of alertness;
  • The preset rotation prevents uncontrolled automatic rotation that may cause entanglement of the brush in the hair;
  • Precise rolling for detaching the handle and leaving the roll in the hair.

When the brush is not turning, the handle 820 may be detached from the brush body 810, leaving the hair wound around the brush body 810 so that the brush body functions as a roll in the client's hair and may be fastened thereto by a rubber band 815 attached to the brush body 810.

The devices according to the present invention may be easily installed in conventional round hair brushes. Alternatively, hair brushes including the devices may be manufactured with different lighting and power generating capabilities, as described in the embodiments above.

FIG. 9 is a schematic drawing of another embodiment of the present invention. According to this embodiment, hairbrush sterilization by UV light is done when the brush is not in use. The hairbrush, similar to the hairbrush depicted in FIG. 8, comprises UV LEDs and is detachable from its handle. The detached rolls may be accommodated in an especially designed receptacle 900, functioning as an internal sterilizer/sanitizer. Receptacle 900 comprises a plurality of carriers 910 connected to a power source 960, internal (as shown) or external, such as a battery or an electric socket. When a roll 920 is mounted on a carrier 910, the UV LEDs inside the roll are lit and sterilization of the roll takes place.

According to embodiments of the invention the brush includes both UV and IR LEDs, where during use of the brush only the IR LEDs are operated, and during sterilization in the sterilizer only the UV LEDs are operated.

In an alternative embodiment, roll 920 does not include UV LEDs, rather the UV LEDs 950 are mounted on the carrier and sterilize the roll/brush from within when it is inserted therein.

Internal sterilization of the roll/brush is important since it provides sterilization to areas otherwise difficult to reach with cleaning means, which may encourage growth of bacterial colonies.

Carriers 910 may be installed at varying distances, to accommodate rolls of different diameters, such as 920 and 930.

Additional UV lamps 940 may be installed inside the hairbrush sterilizer to provide external sterilization of the roll/brush.

The hairbrush sterilizer receptacle 900 may additionally comprise separate carriers serving as chargers for the battery (710, 855).
