Description

[Detailed description of the invention] The present invention relates to a new hair dryer attachment whose outer diameter can be freely increased or decreased. Synthetic resin inner cylinder 2
is inserted into the base end of the outer cylinder 1 so that the inner ends of the outer cylinder 1 and the inner cylinder 2 open toward the hot air outlet (not shown) of the hair dryer main body. A ring portion 3 is integrally provided, and a side port 5 is provided in a wall surface 4 formed by a step between the ring portion 3 and the outer cylinder 1 to blow out hot air from the hot air outlet toward the outer periphery of the outer cylinder 1. At the same time, a rotary operation knob 6, which also functions to close the opening at the end of the inner cylinder 2, is fitted on the tip of the inner cylinder 2 in a non-rotatable manner.
A large number of ventilation holes 7, 7' and an axially long slit 8 are provided between the peripheral wall of the inner cylinder 2 and the peripheral wall of the inner cylinder 2, so that one of them is in a communicating open state no matter what rotational position the inner cylinder 2 is in.
8' and a wide metal plate 10 with holes 9 made of a spring material, which is longer than the outer diameter of the outer cylinder 1, is wound and placed on the outside of the outer cylinder 1. The hooking bent edges 11 and 11' are folded together, and one hooking bent edge 11 is passed through the slit 8 of the outer cylinder 1 to the cutting edge of the slit 8' of the inner cylinder 2, and the other hooking edge 11 is also connected to the cutting edge of the slit 8' of the inner cylinder 2. The bent edges 11' are respectively engaged with the incisal edges of the slits 8 of the outer cylinder 1 in a state that does not inhibit the rotation of the inner cylinder 2 to form a bobbin. A clip 13 is attached to the shaft 14 by the elastic force of the clip 13.

Since the present invention is constructed as described above, by twisting the knob 6, both ends 10' and 1 of the metal plate 10 are attached.
By widening the overlapping width of 0', the diameter of the cylinder formed by the metal plate 10 can be made smaller, and by narrowing it, it can be made larger, that is, thin curls and thick curls. It is extremely convenient to be able to obtain it in a stepless and free state.

In the present invention, stoppers for regulating the rotation angle of the inner cylinder may be provided at appropriate locations, and in the figure, 15 is a hot air blocking wall, 16 is a finger rest, 17 is an inner cylinder removal prevention claw, and 1
Reference numeral 8 indicates a projection for preventing the knob from coming off, and reference numeral 19 indicates a protrusion for preventing the knob from rotating.

Claims (1)

[Scope of utility model registration request] The inner cylinder is twistably inserted into the outer cylinder, and a ring part is attached to and removed from the base end of the outer cylinder with the inner ends of the outer cylinder and the inner cylinder open toward the hot air outlet of the hair dryer main body. In addition, a knob for rotating the inner cylinder is provided at the tip of the inner cylinder, and a large number of ventilation holes and shafts are provided between the peripheral wall of the outer cylinder and the peripheral wall of the inner cylinder, one of which communicates with the other at any rotational position of the inner cylinder. At the same time, a wide perforated elastic metal plate longer than the outer diameter of the outer cylinder is arranged on the outside of the outer cylinder by winding it, and one edge of this metal plate is connected to the slit of the outer cylinder. The hair wound around the bobbin is secured to the incisal edge of the slit in the inner cylinder and the other end to the incisal edge of the slit in the outer cylinder through the bobbin in a manner that does not inhibit the rotation of the inner cylinder. A hair dryer attachment consisting of clips that hold the hair in place.
