Description

TECHNICAL FIELD

The present invention relates to a heat-dissipating plate coupled to a cordless hair styler, and to a cordless hair styler.

BACKGROUND ART

A cordless hair styler is used to make various hair styles in a convenient way regardless of place. If heat is applied to hair interposed between first and second heat-dissipating plates attached to first and second members of the cordless hair styler, a user may easily make a desired hair style.

Referring to FIG. 3, a heat-dissipating plate 300 of a conventional cordless hair styler is provided as a three-layer structure of a ceramic heater 310, a heat-generating plate 320 including additional metal and formed in an upper part of the ceramic heater 310, and a ceramic coating layer 330 coating the heat-generating plate 320. Thus, the heat-dissipating plate 300 does not provide good heat efficiency and consumes too much power to be used for a cordless hair styler.

While the heat-dissipating plate 300 of the conventional cordless hair styler directly contacts the hair, its external surface includes a hard material such as metal or plastic coated with ceramic. The heat-dissipating plate including the hard material does not enclose the entire hair when pressing the hair and does not uniformly transmit heat to the hair. Further, the heat-dissipating plate grasps the hair stiffly and the hair is pulled out or damaged.

DISCLOSURE

Technical Solution

In order to achieve the object of the present invention, a heat-dissipating plate for a cordless hair styler comprises a PCB heater which generates heat; and a rubber sealing member which encloses the PCB heater and directly contacts the hair when applied thereto, is not deformed by the heat generated by the PCB heater and has elasticity.

In order to achieve the object of the present invention, a cordless hair styler comprises first and second members which face each other, are connected to each other by one end of the first member and one end of the second member and form a shape of nippers; a PCB heater which comprises first and second heat-dissipating plates attached to an internal surface of the first and second members, respectively, and facing each other, wherein the first and second heat-dissipating plates generate heat; and a rubber sealing member which encloses the PCB heater.

Advantageous Effect

The present invention may have the following effects. However, it does not mean that a particular exemplary embodiment includes all of, or only, the following effects. Therefore, it should not be understood that the scope of right of the present invention is not limited to the following.

As described above, the heat-dissipating plate for a cordless hair styler is an integrated heat-dissipating plate which transmits heat more efficiently from the heat to the surface of the heat-dissipating plate without an additional heat-generating plate. As a PCB insulating plate is included in a surface of the PCB heater, loss of heat may be prevented. Accordingly, the heat-dissipating plate has good heat efficiency, consumes less power, and is suitable for a cordless hair styler which uses a rechargeable battery.

Further, the heat-dissipating plate for a cordless hair styler includes a soft, elastic rubber sealing member, pulls the hair smoothly, makes a desired hair style without difficulty, and does not badly pull back or pull out the hair. Also, the heat-dissipating plate entirely encloses the hair and transmits heat uniformly to the hair. The heat-dissipating plate for a cordless hair styler includes carbon powder in addition to silicone rubber, and reduces an occurrence of static electricity to the hair when the cordless hair styler is used as compared to the heat-dissipating plate for a conventional cordless hair styler.

Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the range of which is defined in the appended claims and their equivalents.

FIG. 1 is a perspective view of a cordless hair styler according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a cordless hair styler 100 includes a first member 110, a second member 120, a first heat-dissipating plate 140 and a second heat-dissipating plate 150. The cordless hair styler 100 may further include a rechargeable battery 160 and a charging terminal 170 which supply power to the first and second heat-dissipating plates 140 and 150.

One end of the first member 110 is connected to one end of the second member 120 and thus the first and second members 110 and 120 are shaped like nippers to face each other centering on a hinge 130. The first and second members 110 and 120 may move within a predetermined angle, and may be used as a handle of the cordless hair styler 100. The first member 110 or the second member 120 may be attached with a button 180 to control power, and a display window 190 to display power on/off or temperature of the first and second heat-dissipating plates 140 and 150 depending on the degree of pushing the button 180.

The first and second heat-dissipating plates 140 and 150 are attached to an internal surface of the first and second members 110 and 120, respectively, to face each other. The cordless hair styler 100 may be used by putting the hair between the first heat-dissipating plate 140 and the second heat-dissipating plate 150. The first and second heat-dissipating plates 140 and 150 may discharge heat with a certain temperature to change hair style.

The cordless hair styler 100 may further include a rechargeable battery 160 and a charging terminal 170 to receive power in a wireless manner. If the battery 160 is charged by connecting an adaptor (not shown) to the charging terminal 170, the cordless hair styler 100 may be used without a cord, or used by being connected to the adaptor and a cord concurrently while the battery is charged 160.

FIG. 2 is a sectional view of the heat-dissipating plate in FIG. 1.

Referring to FIG. 2, the heat-dissipating plates 140 and 150 include a PCB heater 210 which generates heat, and a rubber sealing member 220 which encloses the PCB heater 210. The heat-dissipating plates 140 and 150 may further include a power terminal 260 to supply power to the PCB heater 210.

Unlike a conventional heat-dissipating plate 300 including a ceramic heater 310, an additional metal heat-generating plate 320 and a ceramic coating layer 330, the heat-dissipating plates 140 and 150 are integrated heat-dissipating plates which mold the PCB heater 210 with the rubber sealing member 220 without the additional heat-generating plate. The heat-dissipating plates 140 and 150 prevent loss of heat generated from the PCB heater 210 and allow the heat from the PCB heater 210 to be supplied to the heat-dissipating plates 140 and 150 without through the additional heat-generating plate.

According to an exemplary embodiment of the present invention, the PCB heater 210 may include a PCB insulating material 230, a heat wire 240, and a heat-generating member 250. For example, a predetermined PCB insulating material 230 which includes phenol resin or epoxy resin to shut off heat may be arranged within the PCB heater 210. The PCB insulating material 230 is an insulating substrate which has a circuit pattern designed for controlling heat generated from a heat wire 240, and shuts off heat from being induced to the PCB insulating material 230 to thereby improve heat efficiency of the PCB heater 210. The heat wire 240 is attached to an upper surface of the PCB insulating material 230 not to overlap the PCB insulating material 230, and may generate heat corresponding to the power supplied by the outside. The heat-generating member 250 is arranged to enclose the heat wire 240 for protection, and may include metal and uniformly transmit the heat from the heat wire 240 to the rubber sealing member 220.

With the foregoing configuration, the PCB heater 210 has good heat efficiency, and consumes less power, and among others, may be used for a cordless hair styler receiving power from a battery. The power supplied by the outside may be adjusted by the degree of pushing the button 180. For example, the PCB heater 210 may generate heat at 170, 190 or 210 degrees.

The rubber sealing member 220 may directly contact the hair if the gap between the first and second members 110 and 120 is narrowed and the first and second heat-dissipating plates 140 and 150 contact each other. The rubber sealing member 220 surrounds the PCB heater 210 and maintains a predetermined temperature with the heat from the PCB heater 210, and transmits the heat from the PCB heater 210 to the hair.

The rubber sealing member 220 includes an elastic material that is not deformed or damaged by heat. The rubber sealing member 220 may entirely and smoothly pull the air and transmit the heat to the hair, reduce the possibility of entangling or pulling out the hair, and prevent damage to the hair. For example, the rubber sealing member 220 may include silicone rubber or urethane rubber.

The rubber sealing member 220 may include highly-conductive carbon powder to prevent static electricity which may arise when contacting the hair. The rubber sealing member 220 is easily discharged and the occurrence of static electricity is reduced if it includes the carbon powder.

According to an exemplary embodiment, the rubber sealing member 220 may include a silicone compound, and preferably, silicon as a main component of 60 to 80 wt % and carbon powder of 20 to 40 wt %. More Preferably, the rubber sealing member 220 may include silicon of 65 to 75 wt % and carbon powder of 25 to 35 wt %.

According to another exemplary embodiment, the rubber sealing member 220 may include a urethane compound, and preferably, urethane as a main component of 60 to 80 wt %, and carbon powder of 20 to 40 wt %.

If the percentage of the carbon powder is less than the foregoing, the effect of preventing static electricity as a result of the carbon component may not occur easily. If the percentage of the carbon powder exceeds the foregoing, the elasticity of the rubber sealing member 220 as a result of silicone or urethane may not occur.
