DESCRIPTION OF THE PREFERRED EMBODIMENTS An eyelash curler according to the present invention comprises a power supply unit using a dry battery, a rechargeable battery or the like as a power supply, a cylindrical gripping unit containing a switch for turning on / off the power supply, and the like. It is composed of a main body composed of a rod-shaped curl part having a heating wire and generating heat, and a cap covering the main body so as to mainly cover the curl part.

The heating wire supporting portion, which is a rod-like base of the curl portion, has a cross section formed in a generally inverted fan shape or an inverted heart shape. By doing so, it is possible to widen the use range angle as a curler. Then, from the front side, a plurality of ribs are formed so as to protrude so as to be orthogonal to the axial direction of the heating wire support portion, and are formed in parallel at regular intervals. Each rib is provided with a hole at the base thereof, at a position in contact with the surface of the heating wire support portion, so as to penetrate straight through all the ribs. A groove in the longitudinal direction of the heating wire supporting portion is provided near the center of the width on the front and back surfaces thereof. Then, one heating wire is assembled so as to penetrate each hole and come into contact with the surface of the heating wire support portion, is folded in a U-shape at the tip of the heating wire and is fitted into the groove, and is fitted into the elongated groove also on the back surface and assembled. .

In addition, in order to confirm the heat generation temperature of the heating wire, the groove is partially made shallow, or portions on both sides of the groove are cut off. In this way, safety can be ensured and the operating temperature can be confirmed.

The terminal of the heating wire is connected to a switch, a power supply, and the like in a cylindrical holding portion. The diameter and length of the heating wire are determined by the required temperature of the heating element, the power supply voltage, and the like. However, it is conceivable that the reciprocation of the curled portion alone is too long. In such a case, it may be arranged in a coil shape in the grip portion and processed. If the resistance value of the heating wire is too small and an overcurrent occurs, a resistor having a required value may be similarly inserted and arranged in the holding portion.

The switch of the power on / off switch is

A color indicating that the switch is on, for example, a color such as red so as to be conspicuous. By doing so, unnecessary battery drain due to forgetting to switch off,
Accidents due to accidental overheating can be prevented.

As another embodiment different from the above, in order to improve the efficiency of transferring the heat of the heating wire to the eyelashes, a thin metal plate having good heat conductivity is formed in front of the heating wire so as to be in contact with the heating wire. The arranged heating plate is arranged. The heating plate is exposed from the base of the rib on the surface of the heating wire support. The length is desirably over the entire area where the plurality of ribs are present. However, if the tip of the heating wire support is tapered, the range is excluded. By curling the eyelashes through such an electric heating plate, heat can be obtained in a wider range, and the curling operation becomes efficient.

As means for arranging the heating plate in the heating wire support portion, a concave portion having a depth from the back surface of the heating wire support portion to the front surface is provided, and an opening is formed between adjacent rib bases on the front surface. Here, an electric heating plate may be fitted from the back side. The heating plate is arranged so that the heating wire is in contact with the back surface of the heating plate. Further, a heating wire holder is fitted so as to close the opening from the back side of the concave portion, and the heating wire is accommodated in a groove provided on the front side of the heating plate holder. Further, a groove for accommodating the heating wire provided on the back side is formed on the back side surface of the electric heating plate holder.

Although the shape of the electric heating plate is a small rectangular shape, the cross section on the short side may be simply flat.
It may be locally arcuate or entirely arcuate. By providing the arc-shaped portion in this manner, when curling the eyelashes, the contact area increases, and the eyelash can be quickly and easily performed. In this case, it is of course more efficient to set the shape of the innermost surface of the concave portion of the heating wire support portion into which the heating plate is to be fitted according to the shape of the heating plate to be fitted. It is.

As described above, according to the first aspect of the present invention, the heating wire is wired on the front and back of the curled portion, and the cross section of the heating wire supporting portion which is the base of the curled portion has an inverted heart shape or Since it is an inverted fan shape, the angle range on the front side is wide,
Therefore, the eyelash curler has a wide range of use, is easy to use, requires no time for eyelash treatment, and is excellent in simplicity and speed.

The heating wire is designed so that it does not come into direct contact with the skin, and a part of the heating wire is formed so that the heating value can be touched with a fingertip. The temperature can be confirmed without using the temperature display means, which contributes to downsizing and cost reduction.

Further, since the switch of the switch provided on the grip portion is moved in conjunction with the mounting of the cap to turn off the switch, it is possible to prevent accidental accidents due to forgetting to turn off the switch. When the switch is turned off, it is covered with a knob, and the grip on the surface of the grip that is exposed as the knob moves when the switch is turned on is colored red, etc., to indicate that it is on. This alerts the user to prevent unnecessary consumption of the battery due to forgetting to turn off the switch and accidents due to accidental overheating.

Further, according to the second aspect of the present invention, since the heat of the heating wire is transmitted to the heating plate having a larger area than the heating wire, the contact surface with the eyelash to be curled is large. Thus, an efficient curling operation can be performed. Further, if the cross section of the electric heating plate has an arc-shaped portion, the state of contact with the eyelashes is further improved, so that a more efficient curling operation can be performed.
