[specific embodiment]

To the utility model electrically heated curler embodiment shown in Figure 4, comprise the outer tube 1 of tubular hollow, the interior pipe that is enclosed within tubular hollow in the outer pipe orifice and the electrothermal layer between hollow outer tube and interior pipe at Fig. 1.

Interior pipe comprises body 2 and cover plate 8, and body 2 has the uncovered bar shaped wire casing 201 in top, the opening of cover plate lid 8 above bar shaped wire casing 201.

The right-hand member of bar shaped wire casing 201 is temperature controlled compartment 202 and terminal base hole 207, is embedded with the terminal base 6 of coaxial three utmost point joints in the terminal base hole 207.

1 lead 603 of drawing from the terminal base 6 of coaxial three utmost point joints passes bar shaped wire casing 201 and is connected with electrothermal layer; Electrothermal layer is a metal heating line 3 in the spiral heating wire casing 211 of managing in being wrapped on body 2 outer walls; Spiral heating wire casing 211 keeps set spacing with generate heat line 3 of metal, and line 3 turn-to-turn short circuits can prevent to generate heat.

The outside that metal heating line 3 is formed heating layers is wound with insulating tape 11, and insulating tape 11 also is that spiral twines, and the rotation direction of insulating tape 11, pitch and spiral fluted rotation direction, pitch are identical, are convenient to process with same equipment the productivity ratio that raising is processed.

In the head 210 of pipe body 2 one ends be exposed at the outside of outer tube 1, outer tube 1 seal (or ultrasonic bonding) with fluid sealant 7 with junctions body 2 two ends.The head 210 of the end that interior pipe exposes has the hanging groove A of 6 rubber bands, and the head of the other end of outer tube 1 also has the hanging groove A of 6 rubber bands.

Temperature control element thermistor 4 and temperature detect switch (TDS) 5 are housed in temperature controlled compartment 202 and the bar shaped wire casing 201.Metal heating line 3, thermistor 4 are connected with external power source through coaxial three utmost point joints with temperature detect switch (TDS) 5.Temperature controlled compartment 202 is isolated with the inner chamber 2a of body 2 fully, the equal and external communications in the two ends of body 2 inner chamber 2a.

Coaxial three utmost point joints of TRS are installed on the terminal base 6 through injection moulding, and terminal base 6 shutoff are in the terminal base hole 207 of the outside opening of body 2 end temperature controlled compartments 202, and coaxial three utmost point joints 601 of TRS are protruding, are convenient to connect power supply and controller.The binding post that coaxial three utmost point joints 601 of TRS are arranged in terminal base 6 is electrically connected with metal heating line 3, temperature detect switch (TDS) 5 through lead 602,603.

One end of the wiring of metal heating line 3 is drawn from the lead 602 of the top of terminal base 6, and the other end is drawn from the connecting line 603 of temperature detect switch (TDS) 5.

The connected mode of two leads 602,603 of drawing from conducting terminal and metal heating line 3 can be stranded or welding, but stranded connected mode is more convenient, and consumable material is few, connect reliable, than soldering environmental protection more.

Temperature detect switch (TDS) 5 is arranged in the position at temperature controlled compartment 202 middle parts, and thermistor 4 is arranged in the right-hand member of temperature controlled compartment 202.

In order to improve the heat conduction of temperature detect switch (TDS) 5 and thermistor 4, be filled with heat conductive silica gel 9 in bar shaped wire casing 201 and the temperature controlled compartment 202.

The interior tube body of present embodiment adopts uncovered bar shaped wire casing not only to simplify mould, has also simplified assembly technology, helps reducing production costs, and boosts productivity.

The structure of the utility model electrically heated curler embodiment 2 such as Fig. 5 are to shown in Figure 7, and be following with the difference of embodiment 1:

Outer tube 1 is wrapped in interior tube outside through injection moulding, and all there is the hanging groove A of rubber band at the two ends of outer tube.For fixing and sealing in outer tube 1 better, the two ends of body 2 respectively comprise the outside bead 205 of 1 figure.Outer tube 1 forms through injection moulding, and the two ends of body 2 are with forming sealing through injection moulding between the endoporus of outer tube 1.Outer tube 1 is wrapped in the periphery of body 2 and metal heating line 3.Two line outlets of interior pipe are all filled by injection molded layers.When assembling, leave the gap between terminal base 6 and the terminal base hole 207, the gap between terminal base 6 and the terminal base hole 207 is filled by injection molded layers.Because sealing is all filled by injection molded layers in spaces all between body 2 and the outer tube 1, outer tube 1 forms through injection moulding, and the outside of heating layer need not the insulating tape reinforced insulation.

The present embodiment electrically heated curler has favorable waterproof property, can guarantee the electrical safety when electrically heated curler uses.
