Description

Heat sink and cordless hair curler

The disclosed technique relates to a heat sink and a cordless hair curler coupled to a cordless hair curler.

A cordless hair curler is a device for producing a variety of hair styles conveniently. When the hair is inserted between the first heat sink and the second heat sink attached to the first member and the second member of the cordless hair curler to heat the hair, the hair can be easily made in the desired style.

Referring to FIG. 3, the heat sink 300 of the conventional cordless hair curler includes a ceramic heater 310, a heating plate 320 made of a separate metal on the ceramic heater 310, and a ceramic for coating the heating plate 320. Since the coating layer 330 has a three-stage structure, thermal efficiency is not good, and therefore, there is a problem in that power consumption is large for use in a wireless hair curler.

In addition, the heat sink of the cordless hair curler is in direct contact with the hair, and the conventional cordless hair curler is made of metal or plastic coated with a hard ceramic material on the outermost material of the heat sink. The heat sink of a hard material does not cover the entire hair when pressing the hair, heat is not evenly transmitted to the hair, and the hair is pulled out or damaged by stiffly holding the hair.

Among the embodiments, the heat sink for the cordless hair curler surrounds the PCB heater, and generates heat, and can directly contact the hair when applied to the hair, and elasticity without being deformed by the heat generated from the PCB heater. The branch includes a rubber seal.

Among the embodiments, the cordless hair curlers face each other and each end is joined to each other by a hinge to form a forceps-shaped first member and a second member, and attached to each inner surface of the first member and the second member to face each other. And a first heat sink and a second heat sink, and each of the first heat sink and the second heat sink includes a PCB heater generating heat, and a rubber sealing material surrounding the PCB heater.

The disclosed technique can have the following effects. However, since a specific embodiment does not mean to include all of the following effects or only the following effects, it should not be understood that the scope of the disclosed technology is limited by this.

The heat dissipation plate of the above-mentioned wireless hair curler is an integrated heat dissipation plate which is not provided with a separate heat dissipation plate, which can transfer heat generated from the heater to the surface of the heat dissipation plate better, and includes a PCB heat dissipation plate on one side of the PCB heater to be lost outside It can cut off heat. Therefore, it is excellent in thermal efficiency and low power consumption, so it is suitable for a wireless iron for charging and using a battery.

In addition, the heat sink of the above-mentioned cordless hair curler is provided with a soft and elastic rubber seal, so as to gently hold the hair to produce a desired hairstyle more easily, it is possible to improve the problem of pulling or pulling the hair severely. In addition, the hair can be wrapped tightly so that heat can be spread evenly on all sides of the hair. In addition, the heat dissipation plate of the above-mentioned cordless hair curler further contains carbon powder in the silicone rubber, and thus, it is possible to reduce the generation of static electricity of the hair when using the cordless hair curler as compared to the heat sink of the conventional curling iron.

The

heat sinks

140 and 150 are different from the conventional heat sink 300 formed of the ceramic heater 310, the metal heating plate 320, and the ceramic coating layer 330, and do not have a separate heat plate. An integrated heat sink formed by molding the heater 210, which prevents heat generated from the PCB heater 210 from being lost to the outside, and transfers heat generated from the PCB heater 210 to the surfaces of the

heat sinks

140 and 150 without passing through a separate heating plate. To be possible.

According to an embodiment, the PCB heater 210 may include a PCB insulation material 230, a heating wire 240, and a heat generating member 250. As an example, a predetermined PCB heat insulating material 230 made of phenol resin or epoxy resin which can block heat may be disposed in the PCB heater 210. PCB insulation material 230 is an insulating substrate formed with a circuit pattern designed to control the heat generated from the heating wire 240, the PCB heater by blocking the heat that can be conducted through the PCB insulation material 230 ( The thermal efficiency of 210 may be improved. The heating wire 240 may be attached to the upper surface of the PCB insulation 230 so as not to overlap each other, thereby generating heat in response to the power applied from the outside. The heating member 250 may be disposed to surround the heating wire 240 to protect the heating wire 240, and may generally be made of metal to evenly transfer heat generated from the heating wire 240 to the rubber sealing material 220.

The PCB heater 210 having the structure as described above may be used in a wireless hair curler, which is particularly powered by a battery because of low power consumption because of its excellent thermal efficiency. The power supplied from the outside may be adjusted according to the state in which the button 180 is pressed, and the PCB heater may generate heat of 170 degrees Celsius, 190 degrees Celsius, and 210 degrees Celsius as an example.

The rubber sealant 220 may directly contact the hair when the first heat sink 140 and the second heat sink 150 contact each other by narrowing the gap between the first member 110 and the second member 120. . The rubber sealing material 220 surrounds the PCB heater 210 to receive heat generated from the PCB heater 210 to maintain a predetermined temperature, and to transfer heat received from the PCB heater 210 to the hair.

The rubber sealing material 220 is made of an elastic material without being deformed or damaged by heat, so that the hair can be smoothly and gently held. Therefore, the heat can be evenly transferred to the hair, and the phenomenon in which the hair is severely pulled or pulled can be reduced, thereby preventing the hair from being damaged. As an example, the rubber seal 220 may be made of silicone rubber or urethane rubber.

In addition, the rubber sealing material 220 may contain carbon powder having good electrical conductivity in order to prevent static electricity that may occur when contacting the hair. When the rubber sealant 220 contains carbon powder, discharge occurs easily and static electricity is reduced.

According to one embodiment, the rubber sealing material 220 may be a silicone-based compound, preferably a compound containing 60 to 80% by weight based on silicon (Silicone), 20 to 40% by weight of carbon powder Can be. More preferably, the compound may include 65 to 75% by weight of silicon and 25 to 35% by weight of carbon powder.

According to another embodiment, the rubber sealing material 220 may be a urethane-based compound, preferably containing 60 to 80% by weight of urethane (urethane) as a main component, containing 20 to 40% by weight of carbon powder Compound.

If the carbon powder is less than the above range may not exhibit the antistatic effect due to the carbon component, if the carbon powder exceeds the above range, the elastic effect of the rubber sealing material 220 due to the silicone or urethane component may not appear well Can be.
