Description

[Detailed description of the invention] The present invention relates to a hair curler.

Conventional hair curlers have a separate hole drilled to form the steam outlet, and the area for wrapping the hair is insufficient by the opening area of the steam outlet, causing the steam to partially adhere and become uniform. There is a problem that it is difficult to obtain a curling effect, and since the heat conductive members on the outer periphery of the hair wrapping body are placed at regular intervals only on half of the outer periphery, the heat conductive members to the curled hair are uneven. Therefore, uniform curls could not be obtained.

The present invention has been made in view of the above-mentioned points, and its purpose is to uniformly transmit heat and steam to the hair without the need to form a separate steam outlet. We offer curling devices.

The gist of the present invention is that a plurality of heat conductive members 35 are annularly disposed around the outer periphery of a cylindrical hair wrapping body 37 to form a cylindrical hair wrapping outer shell 36, and a heating means is provided within the hair wrapping body 37. This hair curler is characterized in that it has a built-in slit-like gap between heat conductive members 35 as a steam outlet 39.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. 1 is
It is a heater for generating heat like a PTC heater,
As shown in FIG. 4, a heat sink 2 is provided to sandwich the heater 1, and is inserted into a heat conduction inner pipe 3 with one end open. A fin 4 is provided protruding from the outer periphery of the opening side of the heat conduction inner pipe 3, and the fin 4 of the heat conduction inner pipe 3 is press-fitted into the heat conduction outer pipe 5 to heat the heat conduction inner pipe 3 and the heater 1. The tip of a cylindrical support 6 made of a thermally poor conductor is inserted into the heat-conducting outer pipe 5 from behind the heat-conducting inner pipe 3, and heat is inserted into the heat-conducting outer pipe 5 to prevent rattling. The rear end of the outer conductive pipe 5 is caulked to the support 6 to form an integral body. Furthermore,
The lead wire 8 of the heater 1 is inserted into the through hole 7 in the support column 6.
is inserted therethrough and electrically connected to the plug 9 provided at the rear end of the support column 6 by soldering. A retaining ring 11 for locking and holding a tank 10 for storing water is press-fitted into the tip of the heat-conducting outer pipe 5, and the tank 10 is slidably held at the tip of the heat-conducting outer pipe 5. the tank 1 by the spring 12.
The water absorbing body 13 at the rear of the 0 and the tip of the heat conducting inner pipe 3 are elastically separated from each other.

Reference numeral 37 is a hair winding body, which includes an inner heat conductive pipe 3 made of stainless steel, an outer heat conductive pipe 5 made of aluminum, and a bristle substrate 16 made of silicone rubber in which bristles 15 are integrally molded and arranged in rows along the body axis. and a heat conductive member 35 made of aluminum. In the heat conducting outer pipe 5, square holes 40 for blowing out steam are arranged in a staggered array along the body axis, and the 40 rows of square holes are spaced apart in the circumferential direction of the pipe. Bristle insertion holes 41 are bored in the heat conduction member 35 in correspondence with the bristles 15, and locking pieces 42 having a thinner wall than the width of the square hole 40 protrude from both side edges of the heat conduction member 35. Bristle board 16
A plurality of heat conductive members 35 are arranged in a ring shape around the outer circumference of the outer heat conductive pipe 5. The heat conductive member 35 is attached to the heat conductive outer pipe 5 with the bristle substrate 16 in between, and the locking piece 42 is inserted into the square hole 40 and bent to the back surface of the heat conductive outer pipe 5.
Further, the bristle 15 projects outward through the bristle insertion hole 41. At this time, the heat conduction inner pipe 3
A part of the fin 4 is brought into contact with the locking piece 42. Further, the gap formed between the square hole 40 and the locking piece 42 is used as a steam flow hole 43, and the gap between both side edges of the adjacent heat conductive members 35 is used as a steam outlet 3.
It is listed as 9. Both side edges of the heat conduction member 35 are curved inward as shown in FIG.
9 is wider as it goes outward. Therefore, when the hair (H) is wrapped around the hair, a tunnel-like cavity 44 is formed as shown in the figure, which makes it easier for steam to flow in the direction of the body axis, allowing the steam to spread throughout the hair. Further, since the bristle substrate 16 is sandwiched between the heat conductive member 35 and the heat conductive outer pipe 5, the heating efficiency of the bristle 15 is improved and curling is improved. Furthermore, since the fins 4 of the heat conduction inner pipe 3 are in direct contact with the heat conduction outer pipe 5 and the heat conduction member 35 via the locking piece 42, heat can be efficiently transmitted to both.

Reference numeral 19 denotes an annular (approximately C-shaped) sliding ring that is partially cut out and partially thinned, and as shown in FIG. A plurality of sliding rings 19 are rotatably fitted at substantially the same intervals (FIG. 3).

21 is a temperature indicating tape. Reference numeral 23 denotes a substantially cylindrical handle composed of a pair of half cylinders 22a and 22b that are combined with each other.
2a and 22b, insert the support column 6 into the handle 23, integrate the half cylinders 22a and 22b with the locking claw 28, configure the bearing part 26 with the sliding ring 19, and insert the support column 6 into the handle. Furthermore, a rotating connector 25 at the end of the power cord 24 is inserted into the rear end of the handle 23 and fixed, and a plug 9 at the end of the support column 6 is connected to the rotating connector. 25, and the plug 9 side of the rotary connector 25 can freely rotate. In this way, the hair winding drum 37 is integrated with the pillar 6, and since the pillar 6 is rotatably supported within the handle 23, the mechanism for rotating the hair winding trunk 37 is the same as that of the hair winding trunk 37. It is located inside the handle 23 rather than inside, which simplifies the structure of the hair winding cylinder 37 and improves the heat conduction efficiency from the heater 1 to the surface of the hair winding cylinder 37. In addition, the support column 6 is rotatably supported by a bearing part 26 within the handle 23 constituted by a pair of half-cylindrical bodies 22a and 22b, and the interval between the bearing parts 26 is made approximately equal to the width of the hand. Handle 23
The force applied to the handle 23 when gripping the bearing part 26
It is received by the pillar 6 through the handle 23, and the force when gripping the handle 23 does not create a gap between the half cylinders 22a and 22b, and the pillar 6 and the hair wrapping body 37 can also be rotated stably. Moreover, since the support column 6 is made of a thermally poor conductor, the heat of the heater 1 is difficult to be transmitted to the bearing part 26 and the handle 23.
The life of the handle 23 is kept long and the temperature of the handle 23 is kept low. Also, when the hair winding cylinder 37 rotates,
The plug 9 side of the rotary connector 25 rotates, the lead wire 8 is not twisted within the hair winding cylinder 37 and the pillar 6, and the force of the lead wire 8 is not applied to the pillar 6, allowing the hair winding cylinder 37 to rotate smoothly. .

Reference numeral 29 is a thin, elliptical ring-shaped elastic locking ring, which has a protrusion 30 on the inner circumferential surface on its short diameter side.
is installed protrudingly. The lower surface of the protrusion 30 is a locking surface 30b
The upper surface of the protrusion 30 is inclined as a flank surface 30a. An operation push button 31 is provided protruding from one of the outer peripheral surfaces on the longer diameter side, and a fork-shaped locking protrusion 33 is provided on the longer diameter side opposite to this operation push button 31. This locking ring 29 is delivered inside the handle 23, and has a locking protrusion 33 fitted into a recess 32 on the inner circumference of the handle 23 to prevent it from turning. It is made to protrude from the top.
Further, a support 6 is inserted into the locking ring 29, and a plurality of recesses 34 are provided in the heat-conducting outer pipe 5 and the support 6 in correspondence with the protrusions 30 of the locking ring 29. As shown in FIG. 5, the elasticity of the locking ring 29 causes the protrusion 30 to fit into the recess 34, thereby stopping the rotation of the hair wrapping body 37 and the support column 6. When the operating push button 31 is pushed into the handle 23 from above the handle 23, the locking ring 29 expands elastically, the protrusion 30 comes out of the recess 34, and the hair wrapping cylinder 37 and the support column 6 rotate freely. When the operating push button 31 is released, the locking ring 29 returns elastically and the hair wrapping cylinder 37 is locked again.
47 is a stopper for preventing the locking ring 29 from being bent too much. Here, A in the figure is the supported length of the locking protrusion 33 of the locking ring 29, and D is the gap between the outer circumferential surface of the heat-conducting outer pipe 5 and the bottom of the inner circumferential surface of the locking ring 29. Yes, A
>D. Moreover, only the locking surface 30b of the protrusion 30 is made to contact the recess 34. However, if a force is generated in the heat conductive outer pipe 5 in a clockwise direction due to hair being wrapped around it in the locked state, the protrusion 30
The distance between B and the edge of the recess 34 becomes 0, and furthermore, D
Even if A>D, the locking protrusion 33 will not come off from the recess 32 of the handle 23 and will remain locked. In addition, in the case of a clockwise direction, it is rotated in A, and in the case of a counterclockwise direction, it is rotated in B, but in both cases, force is generated in the direction in which the operation push button 31 of the locking ring 29 is pushed up, and as a result, the operation push button 31 sinks and is locked. This prevents inadvertent release of .

Then, the hair H is wound around the outer periphery of the hair winding body 37 while the hair winding body 37 is kept locked, and the heater 1
When the tip of the tank 10 is pressed to bring the water absorbing body 13 into contact with the tip of the heat-conducting inner pipe 3, steam is generated and the hair can be curled even more strongly. It is. To unwind the curled hair, press the operation button 31 to release the lock on the hair curler 37, and then pull the hair curler apart.
However, it rotates freely and the hair H can be easily removed without getting tangled. Further, since the rotation stopping means is constituted by the locking ring 29, the structure is simple and the length of this portion can be shortened.

As described above, the present invention forms a hair wrapping shell by disposing a plurality of heat conductive members in an annular manner around the outer periphery of a cylindrical hair wrapping body, so that the hair wrapping shell is always in the same state regardless of how the hair is wrapped. This has the advantage that the hair can come into contact with the heat conductive member and uniform curls can be obtained. In addition, the heating means is built into the hair wrapping body, and the slit-shaped gap between the heat conductive members is used as the steam outlet, so there is no need to form a separate steam outlet. Since it exists in the form of slits, it has the advantage that steam does not stick to parts of it and the appearance is smooth.
