Description

Portable curling iron {Portable curling iron}

The present invention relates to a portable hair iron, and more particularly, to a portable hair iron with improved power consumption and safety of the hair iron.

Hair iron is used in a beauty salon or at home, and is an electrothermal hairdressing apparatus used to produce a hair style desired by a user using heat. Conventional hair iron, which is an electrothermal beauty device, has always been used to wire the external power source.

However, this wired hair iron has a problem in that the external power must always be provided, and a lot of restrictions on the user's movement for the production of various hairstyles.

Recently, a portable hair iron that can be used wirelessly using a battery has been disclosed.

However, such a portable hair iron generates a heater using only battery power, and since the heat of the heater is immediately released to the outside through the heat transfer plate, power consumption is large and inefficient and ineffective compared to the power of the battery. That is, there is a problem that the wireless use time is extremely short.

In addition, since the portion of the heat transfer body to which heat is transferred to the outside during the use of the hair iron is always exposed to the outside, there is a problem in that there is a risk of causing a burn in contact with the skin of the user.

Accordingly, an object of the present invention is to provide a portable hair iron which can be used for a long time efficiently due to low power consumption and can prevent a safety accident in which a user is burned.

The object is, according to the present invention, in the portable hair iron, each of the heat transfer plate coupling portion is formed on one side in the longitudinal direction, and the other side of the longitudinal coupling is mutually hinged so that the two heat transfer plate coupling portions can access and maintain the access state and spaced apart from each other A pair of casings; A heat transfer member of a heat storage and a conductive material coupled to each of the heat transfer plate coupling portions having a heat storage portion accommodated inside the casing and a heat transfer plate portion exposed to the outside of the casing; A thermal heater inserted into the heat storage unit; A power supply unit provided in one region of the casing to charge an external supply power and having a charge battery supplying heating power to the thermal heater; A temperature sensor for sensing a temperature of the heating element; The external supply power is charged to the power supply unit and / or heat the thermal heater to preheat the heating element, while comparing the temperature of the heating element detected by the temperature sensing sensor with a preset temperature It is achieved by a portable hair iron, characterized in that it comprises a microcomputer to heat the thermal heater with the power charged in the power supply.

At this time, the microcomputer charges the external battery to the rechargeable battery through the battery charging circuit while the external power connection means and the power connection circuit are connected, and when the preheat switch is turned on, the external battery is charged to the rechargeable battery. The heating element is preheated by being supplied to the thermal heater through the heating element driving circuit, and when the external power source and the power connection circuit are cut off while the charging battery is charged, the heating element is transferred from the temperature sensing sensor. When the temperature is less than the predetermined temperature of the predetermined heating element, it is preferable to transfer the power charged in the rechargeable battery to the thermal heater to heat the thermal heater.

On the other hand, either one of the casing is formed with a first guide rib from the central region toward the heat transfer plate coupling region, the other casing is formed with a second guide rib in the heat transfer plate coupling region; The first and second guide grooves corresponding to the first and second guide ribs, the second guide rib is engaged with the second guide groove while moving along the first guide rib in the approach state of both casings It is effective to include a locking slider which locks the access state of both casings.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is a perspective view of a portable hair iron according to the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a cross-sectional view taken along line III-III of FIG. 1. As shown in these drawings, the portable hair iron 1 according to the present invention has a main body 10 forming an appearance, and a heat transfer plate assembly 20 installed on one side in the longitudinal direction of the main body 10 to generate heat by power supply.

To this end, the first guide rib 11a is formed in the casing 11 to which the locking slider 15 is coupled from the center region toward the heat transfer plate coupling region, and the second guide rib is formed in the heat transfer plate coupling region in the other casing 11. 11b is formed, and the first and second guide grooves 15a and 15b corresponding to the first and second guide ribs 11a and 11b are formed inside the locking slider 15. That is, the locking slider 15 is coupled to the first guide groove 15a and the locking slider 15 of the locking slider 15 when the locking slider 15 is located in the central region of the main body 10 in the approaching state of both casings 11. When only the first guide rib 11a of the casing 11 is engaged and the locking slider 15 is pushed to the heat transfer plate coupling portion 11c in a state where both casings 11 are approached, the locking slider 15 moves. As the second guide rib 11b of the other casing 11 is engaged with the second guide groove 15b of the locking slider 15, the access state of both casings 11 is locked. When unlocking the approaching state of both casings 11 and pushing the locking slider 15 in the opposite direction, as shown in FIG. 4, both casings 11 are spaced apart by the elastic force of the hinge spring 13a.

The locking slider 15 prevents a user from being burned by contact with the skin and the heating plate due to user carelessness when both casings 11 are left in a spaced state as shown in FIG. 4 in the heating state of the heating plate to be described later. To do this.

The heat transfer plate assembly 20 includes a heat transfer body 21 coupled to the heat transfer plate coupling portion 11c of the casing 11, a thermal heater coupled to the heat transfer body 21, and between the heat transfer body 21 and the casing 11. It has an insulator interposed in it.

The heat transfer body 21 is integrally formed with the heat transfer plate portion 21a and the heat transfer plate portion 21a which are exposed to the outside of the heat transfer plate coupling portion 11c of the casing 11 and is connected to the heat transfer plate coupling portion 11c of the casing 11. It is made of a metal material such as aluminum or copper having excellent thermal conductivity and heat storage property so as to have a heat storage unit 21b accommodated therein. The heat accumulator 21b is provided with a heater coupling groove 21c to which the thermal heater is coupled. The heater coupling groove 21c is preferably formed in the vertical direction in the central region of the heat storage portion 21b. This is to allow the heat transferred from the thermal heater to be quickly conducted to the entire region of the heat storage portion 21b and then transferred to the heat transfer plate portion 21a.

The thermal heater is made of a material such as a metal plate or a hot wire having excellent heat generating performance. The thermal heater is electrically connected to the heating element driving circuits 46d and 46d, which will be described later, to generate heat by the power supplied from the power supply unit 30 to generate and heat the heating element 21.

The power supply unit 30 includes a battery accommodating member 31 coupled to one of the two casings 11 and a rechargeable battery 33 accommodated in the battery accommodating member 31. On both sides of the battery accommodating member 31, a power connection terminal electrically connected to the control circuit board 46 to be described later is provided to correspond to both ends of the battery. In addition, the rechargeable battery 33 preferably uses a lithium ion battery in consideration of a charging capacity, a charging speed, and a lifetime. Of course, other rechargeable batteries 33 such as nickel-metal hydride batteries may be used according to the conditions, and may replace general batteries when the rechargeable batteries 33 consume power.

As shown in FIG. 6, the control unit 40 includes a temperature sensor 41 for sensing a temperature of the heating element 21, a switching unit 43 for turning on / off an operation of the hair iron 1, and Control circuit board for controlling the drive of the hair iron 1, such as the external power connection means 45 for connecting the power supply unit 30 and an external power source, the heat generation of the heating element 21 and the charging of the charge battery 33, etc. Has 46.

The temperature sensor 41 contacts a region of the heating element 21 in a state in which it is electrically connected with the control circuit board 46 to sense the temperature of the heating element 21 and transmit the temperature to the microcomputer of the control circuit board 46. It is.

The switching unit 43 is a power switch 43a for turning on / off the driving of the hair iron 1 and a preheating switch 43a for turning on / off an operation of preheating the heating element 21 in a state of being connected to an external power source. Has These switches are electrically connected to the switch connecting circuit 46a of the control circuit board 46, which will be described later, while being installed to be exposed to the casing 11 of either casing 11 to the outside.

The external power connection means 45 is connected to the external power connection terminal exposed to the outside of the casing 11 in an electrically connected state with the power connection circuit 46c of the control circuit board 46 to be described later, the external power connection terminal. It may be provided in a form having a separate adapter that is connected to an external power source having a connection terminal to be supplied to convert AC power to DC power.

Alternatively, the external power connection means 45 is connected to an external power source in a state where an adapter for converting and supplying AC power to DC power is built-in, and a cradle-type cradle provided with a contact terminal and a control circuit board 46 to be described later. It may be provided as an external power contact terminal that is exposed to the outside of the casing 11 in electrical connection with the power connection circuit 46c to electrically contact the contact terminal of the stationary cradle. In this case, the main body 10 and the cradle-type cradle will have a mutual coupling structure.

The control circuit board 46 includes a switch connecting circuit 46a electrically connected to the switching unit 43, a battery charging circuit 46b electrically connected to the power supply unit 30, and charging the rechargeable battery 33. The power supply connection circuit 46c connects the external power connection unit 45, the switch connection circuit 46a, and the battery charging circuit 46b, and is transmitted through the power connection circuit 46c and / or the battery charging circuit 46b. The heating element driving circuits 46d and 46d for transmitting the power to the heating element 21 and the driving of the hair iron 1 in accordance with the switching operation of the switching unit 43 and at the same time the temperature sensing sensor 41 ) And a microcomputer 46e for controlling the charging of the rechargeable battery 33 and the heat generation of the heat transfer body 21. This control circuit board 46 is housed in the board receiving portion 11d of the casing 11.

The microcomputer 46e charges the external battery to the rechargeable battery 33 through the battery charging circuit 46b while the external power connecting means 45 and the power connecting circuit 46c are connected. In addition, the microcomputer 46e turns on the preheating switch 43a of the switching unit 43 to the heating element 21 through the heating element driving circuits 46d and 46d while charging the external battery to the charging battery 33. The heat transfer body 21 is preheated by being supplied.

In addition, the microcomputer 46e uses the hair iron 1 wirelessly while the rechargeable battery 33 is charged (that is, the external power connection unit 45 and the power connection circuit 46c are blocked). If the temperature of the heat transfer body 21 transmitted from the sensing sensor 41 is less than the predetermined temperature of the predetermined heat transfer body 21, the power of the charge battery 33 is transferred to the thermal heater to heat the thermal heater 21 ) To the proper temperature.

By this configuration, the use and driving of the portable hair iron 1 according to the present invention will be described.

First, when the hair iron 1 is not used, it is connected to the external power supply connecting means 45 to charge the charging battery 33. At this time, the microcomputer 46e charges only the charging battery 33 through the power connection circuit 46c and the battery charging circuit 46b when the signal of the preheat switch 43a transmitted through the switch connection circuit 46a is off. When the preheating switch 43a is on, the heating element 21 is preheated at the same time as charging. At this time, heat transferred from the heater is accumulated in the heat storage unit 21b of the heat transfer body 21. On of the preheating switch 43a is used to save preheating time in an individual or a beauty salon with a high frequency of use of the hair iron 1.

On the other hand, when the hair iron 1 is detached from the external power connection means 45 and used wirelessly, a hair style is produced by directly using the heat of the preheated heat transfer body 21 at the same time as the charging, or the charging battery 33 By heating the heater by the power transmitted through the heat transfer element driving circuit (46d, 46d) from the heat accumulator 21 to generate heat and heat to produce a hairstyle.

At this time, since the heat storage unit 21b is formed in the heat transfer body 21, heat transferred from the heater to the heat transfer body 21 is accumulated in the heat storage unit 21b and is discharged to the outside through the heat transfer plate unit 21a. The heat transfer body 21 can be generated while minimizing the amount used.

In addition, when the temperature of the heat transfer element 21 drops when the hair iron 1 is used, the temperature sensor 41 detects this and transmits it to the microcomputer, and the microcomputer supplies the power charged to the rechargeable battery 33 to the heater to the heater. The heat-generating element 21 is generated by heat generation. In this case, since the heat transferred from the heater is transferred to the heat transfer plate portion 21a while being accumulated in the heat storage portion 21b of the heat transfer body 21, the heat transfer body 21 can be generated while minimizing the power supply.

On the other hand, when the hairstyle is suspended for a while, when the sliding slider 15 is pushed toward the heat transfer body 21 while both casings 11 are approached, the locking slide 15 blocks the external exposure of the heat transfer body 21. While locking the access state of both casing (11), as shown in FIG. Thereby, the image by user's carelessness can be prevented beforehand.

As described above, the heat accumulator having excellent heat storage performance is formed on the heat transfer body, and the heater is heated by the power source of the rechargeable battery to accumulate the heat accumulator, thereby generating the heat generator with minimal power consumption. Thereby, hair iron can be used for a long time with little power consumption.

In addition, it is possible to lock both casing approach state while blocking the external exposure of the heat transfer body, it is possible to prevent the heat transfer body from being burned in contact with the skin of the user.

As described above, according to the present invention, it is possible to efficiently use for a long time because the power consumption is low, and to provide a portable hair iron that can prevent a safety accident that a user burns.
