The main body fitting cylinder 18 of the attachment 11 is provided with a positioning groove 22 (Fig. 5) along the axial direction on the inner surface, an engaging groove 23 along the same direction on the outer surface, and an inlet/outlet following one end of the engaging groove 23. A notch 24 for use is provided. A click projection 26 is provided in the engagement groove 23. The positioning groove 22 is a positioning protrusion (not shown) of the main body 10.
The rotation of the attachment 11 is prevented.

A ring-shaped operator 27 is rotatably fitted onto the operator fitting portion 20 . The operator 27 is connected to the main body 10
It has approximately the same outer diameter as the main body 10, and is coaxial with the main body 10. The operator 27 has a switch operation part 29 on one side and an attachment attachment/detachment part 28 on the inner surface of the other side. The attachment attachment/detachment portion 28 is comprised of a pin-shaped engagement protrusion, and is detachably engaged with the engagement groove 23 (see FIG. 4) of the attachment 11. The switch operation part 29 is a lever-shaped member extending in the axial direction, and is inserted into the main body 10 through a slit 30 provided in the main body 10. The switch operating section 29 is provided with a cam groove 31 extending diagonally, and a sliding switch 32 mounted inside the main body 10 is provided with a cam groove 31 extending diagonally.
The slide button 32a is engaged with the cam groove 31. The slide button 32a moves in the axial direction of the main body 10. The switch 32 turns on and off the heater 16 and the motor 15 of the blower 14, and at one end of the slide stroke of the slide button 32a it is in the off state (both the motor 15 and the heater 16 are off), and in the middle it is in the cold air state (only the motor 15 is turned off). The other end is in a hot air state (both the motor 15 and the heater 16 are energized). The slide button 32a is the operator 27
The cam groove 31 is slid by the rotation of the operator 27, but the rotation angle of the operator 27 and each operation are
As shown in the figure, the hot air state, cold air state, off state, and removal state are performed in this order. Note that the cam groove 31 is provided with a relief portion 31a for allowing rotation from the OFF state to the detached state. Further, the operator 27 is provided with an operation display window 33, and an operation display visible through the operation display window 33 is printed on the operator fitting portion 20 of the main body 10.

45 is a thermoswitch, 32 is a switch, and 46 is a plug. The switch 32 has two contacts a and b.
has.

With this configuration, attachment 11
is guided by the positioning groove 22 and the positioning protrusion of the main body 1 and is fitted into the attachment fitting portion 21 of the main body 10 at a predetermined rotation angle (FIG. 10A).
Thereafter, by rotating the operator 27, the attachment attachment/detachment part 28 goes over the click protrusion 26 of the attachment 11 and moves into the engagement groove 2.
3, and the attachment 11 is prevented from coming off. By rotating the operator 27 of the switch 32, the slide button 32a is slid by the inclination of the cam groove 31. FIG. 10B shows the switch 32 in the OFF state, at which time both contacts a and b in FIG. 9 are open. FIG. 10C is the cold air position, and only contact a in FIG. 9 is closed. Figure 10 D is the hot air position, and the contact points a and b in Figure 9
Both are closed. To remove the attachment 11, rotate the operator 27 in the opposite direction. As a result, the attachment attachment/detachment portion 28 comes out from the engagement groove 23 to the entrance/exit notch 24, and the attachment 11 can be removed. (Figure 10A). Since there is a click protrusion 26 just before the attachment attachment/detachment part 28 comes out of the in/out notch 24, the operator 27
The rotation resistance is large and it cannot be removed easily. The switch 32 is turned off by rotating the operator 27 in the attachment removal direction, but before the attachment 11 is removed, it operates in the order of cold air state and off state, so it will be removed after the attachment 11 has cooled down. Easy to remove by hand.

In this way, attachment and detachment of the attachment 11 and operation of the switch 32 are performed, but since there is no extra protrusion in the part of the main body 10 that is held by the hand, it is easy to hold in the hand and it is easy to set the hair. In addition, since the operator 27 does not protrude from the main body 10 and is not operated by pushing the operator 27 inadvertently,
7 can be moved without causing the attachment 11 to come off or the switch 32 to be operated. In addition, the switch 32 can be switched and the attachment 11 can be attached or detached by simply operating the operation 27, making it easy to use, and there is no need to provide a separate operator for the switch 32, making it easy to hold.

In the above embodiment, the attachment groove 23 was provided in the attachment 11 and the protrusion-like attachment attachment/detachment part 28 was provided in the operating element 27, but conversely, an engaging protrusion was provided in the attachment 11, and the operating element 27 was provided with an engaging protrusion. The attachment attachment/detachment portion 28 may be shaped like a groove.

〔Effect of the invention〕

In the hair curling device of the present invention, the operating means does not protrude from the main body, so the operating section of the switch and the operating section for attaching and detaching the attachment are not moved inadvertently, and it is easy to hold and set the hair. In addition, the switch can be changed and the attachment can be attached and detached simply by operating the operator, making it easy to use and eliminating the need for a separate operator for the switch, making it easy to hold. Also,
The heater switch is turned off by rotating the control in the attachment removal direction, but the heater switch is configured to operate in the order of cold air state and off state before the attachment is removed, so it is removed after the attachment has cooled down. This has the effect of making it easier to remove by hand.
