Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair curler that can unwind the curled hair without tangling it while rotating the brush body after winding hair around a brush body.

In the conventional hair curler of this type, as shown in FIG. 1, rotation and stopping of the brush body 4 were switched by a sliding operation push button 3'. However, the sliding type operation push button 3' has a structure in which a compression coil spring or the like is provided inside to return the operation push button 3', and the number of parts is 2.
In addition, it was not easy to assemble the spring because the compression coil spring had to be bent while being assembled.

The present invention has been made in view of the drawbacks of the conventional examples described above, and its purpose is to simplify the assembly of brush body rotating parts by simplifying the parts for controlling the rotation of the brush body. To provide a hair curling device that can improve hair quality.

The hair curler of the present invention has an elastic annular locking ring 2 housed in a cylindrical handle 1,
An operation push button 3 for bending the locking ring 2 is provided on the outer periphery of the locking ring 2 and protrudes from the handle 1, and the base of a brush body 4 for winding hair is rotatably delivered into the handle 1. The locking ring 2 is loosely inserted into the locking ring 2, the inner periphery of the locking ring 2 is engaged with the outer periphery of the base of the brush body 4 to prevent rotation of the brush body 4, and the locking ring 2 is moved toward the center using the operation push button 3. When pressed, the locking ring 2 is expanded in a direction perpendicular to the pressing direction to release the engagement, thereby achieving the above object.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. Reference numeral 11 denotes a heater for generating heat, and a heat sink 12 is provided to sandwich the heater 11, and this is inserted into a jacket tube 13 with one end open. The mantle tube 13 is press-fitted into the metal pipe 15, and the mantle tube 13 and the heater 11 are assembled into the metal pipe 15.
Furthermore, the tip of the cylindrical support 16 made of a thermally poor conductor is inserted into the metal pipe 15 from behind the mantle tube 13, and the rear end of the metal pipe 15 is caulked to the support 16 as shown in FIGS. 4 and 5. As shown in the figure, it is an integrated object. Further, a lead wire 18 of the heater 11 is inserted through a through hole 17 in the support 16 and is electrically connected to a plug 19 provided at the rear end of the support 16 by soldering. A retaining ring 21 is press-fitted into the tip of the metal pipe 15 to lock and hold a tank 20 for storing water. As a result, the water absorbing body 23 at the rear inside the tank 20 and the tip of the mantle tube 13 are elastically separated from each other. or,
The outer periphery of the metal pipe 15 is covered with a prismle 25 having a large number of comb teeth 24 projecting from it, thereby forming a brush body 4 as shown in FIG. Reference numeral 26 denotes a substantially C-shaped sliding ring with a portion cut out, and is rotatably fitted into grooves 27 on the outer periphery of both ends of the support column 16. In addition, 30 is a steam ejection hole, and 31 is a temperature-indicating tape. Reference numeral 1 denotes a substantially cylindrical handle composed of a pair of half cylinders 32a and 32b that are combined with each other.The support 16 is inserted into the handle 1 by sandwiching the support 16 between the half cylinders 32a and 32b from both sides, and then the support 16 is inserted into the handle 1. A rotating ring 26 is fixed in the handle 1 to rotatably support the column 16, and a rotary connector 34 at the end of the power cord 33 is attached to the rear end of the handle 1.
The plug 19 at the end of the support column 16 is electrically connected to the rotary connector 34, and the plug 19 side of the rotary connector 34 can freely rotate. Reference numeral 2 denotes a thin-walled annular elastic locking ring, with a thick-walled operation push button 3 provided on its upper part, locking protrusions 5 protrudingly provided on both sides of its inner peripheral surface, and a positioning protrusion 8 on its lower part.
is installed protrudingly. This locking ring 2 is the handle 1
The operating push button 3 is exposed through the opening 7 of the handle 1, and the positioning protrusion 8 is fitted into a recess 9 on the inner surface of the handle 1 to prevent the locking ring 2 from rotating within the handle 1. Support post 16 at the base of brush body 4
is loosely inserted into the locking ring 2, and a locking recess 6 that can engage with the locking protrusion 5 is provided at the base of the brush body 4 at a position facing the locking ring 2 along the circumferential direction. They are provided for each interval. Normally, the locking protrusion 5 engages with the locking recess 6 to prevent the brush body 4 from rotating (as shown by the solid line in FIG. 7), but the operation push button 3 is pressed from above the handle 1. When the handle 1 is pushed into the handle 1, the locking ring 2 expands elastically as shown by the imaginary line in FIG. When the operating push button 3 is released, the locking ring 2 returns elastically and locks the brush body 4 again. 10
is a stopper for preventing the locking ring 2 from bending too much. By providing this stopper 10, it prevents an increase in stress caused by pressing the operation push button 3 too much, protects the locking ring 2, and also protects the operation pushbutton. 3 and the brush body 4 are prevented from coming into contact with each other, and the rotation of the brush body 4 is not hindered.

Thus, the hair can be wound around the outer periphery of the brush body 4 while the brush body 4 is kept locked, and the hair can be curled by generating heat using the heater 11.
When brought into contact with the tip of the mantle tube 13, steam is generated, making it possible to curl even more strongly. To unwind the curled hair, push the operating button 3 to unlock the brush body 4, and pull the hair curler A apart, the brush body 4 will rotate and the hair can be easily removed.

FIGS. 8 and 9 show other examples of the present invention, in which a heater 11 and a blower (not shown) are provided in the handle 1, and the brush body 4 and the handle 1 are brought into direct contact with each other, so that the bearing part 14 is It was formed.

As described above, the present invention includes an elastic annular locking ring housed within a cylindrical handle, an operation push button for bending the locking ring provided on the outer periphery of the locking ring, and protruding from the outside of the handle. The base of the brush body for winding hair is rotatably delivered into the handle and loosely inserted into the locking ring, and the inner circumference of the locking ring is engaged with the outer circumference of the base of the brush body to prevent rotation of the brush body. However, since the locking ring is pushed toward the center using the operating push button, the locking ring is expanded in a direction perpendicular to the pressing direction to release the engagement, so pressing the operating push button causes the locking ring to bend. The lock of the brush body can be released by releasing it from the base of the brush body, and when the operating pushbutton is released, the locking ring elastically returns and locks again, and the brush body can be rotated only by the annular locking ring. - It has the advantage of being able to control the lock, eliminating the need for a separate spring, reducing the number of parts to one, eliminating the need to jump the spring during assembly, and improving assembly efficiency.
