Description

Heating rod of hair iron

The present invention relates to a heating rod for curling the hair in the hair iron to become a perm. More specifically, the initial heating speed is fast, the perm temperature restoring force is fast, and the perm temperature control is very accurate. It is about the heating rod of iron.

In general, the hair iron is provided with a heating rod that the hair is wound to receive a thermal energy to be a perm, and the heater is built in.

In addition, since the heating rod has to be wound around the hair, a circular heating rod is adopted, and a heater used in the heating rod is a relatively thin and flat type of conventional heater (PTC heater) or ceramic heater.

Therefore, while the diameter of the heating rod is large while the heater is flat, when the heater is embedded in the heating rod, there was no choice but to use a separate heat transfer member.

That is, in the past, as shown in (a) of FIG. 1, the heater 3 is interposed between the pair of half-moon heat transfer members 2 inside the circular metal heating element 1, but this is caused by the heating rod. The disadvantage is that the weight is heavy and the initial heat transfer rate is slow.

Accordingly, the heater 3 is placed between the pair of heat transfer plate members 2 'made of copper as shown in FIG. 1 (b) to be built in the metal heating element 1, thereby making it lighter. Since heat energy of) is transferred to the metal heating element 1 through the heat transfer plate 2 ', heat transfer does not proceed quickly.

Since the heat transfer plate 2 'is made of a thin copper plate, not only the elasticity is not large due to the characteristics of the material, but also the elasticity decreases with long-term use, so that the heat transfer plate 2' does not adhere to the metal heating element 1 properly. Therefore, there is a problem that the heat transfer function to the metal heating element 1 can not be properly performed due to the gap.

In particular, the heat transfer member 2 or the heat transfer plate member 2 'must be closely adhered to the inner surface of the metal heating element 1 so that the heat transfer is satisfactorily achieved. However, there is a disadvantage in that heat transfer efficiency is low due to manufacturing tolerances. It is caused by a problem of slowing the initial heat generation rate and causes the perm temperature restoring force of the heating rod to deteriorate at the time of permeation.

In addition, since the number of parts is high and the heater 3 should be assembled between the pair of the heat transfer member 2 or the heat transfer plate member 2 'so as to be assembled in a state in which the metal heating element 1 is in close contact with the inner surface, the assembly is precisely assembled. Since it is not easy and the assembly work is complicated and many, there are problems such as poor assembly, reduced productivity and increased cost.

And since the structure is simply assembled by the screw (6) to the connecting member (5) connected to the handle case (4) as shown in Figure 1 (c) structure that can not be in close contact with the inner circumferential surface of the metal heating element (1) Since the hair is wound and the thermal energy of the metal heating element (1) is subjected to thermal energy and the deviation of the set temperature of the temperature control unit is severe, there is a disadvantage that the temperature control is not made accurately, these disadvantages to the permist (beauty salon) The perm treatment is performed by a roughly predicted perm temperature, which causes a problem of preventing a good perm operation.

When the present invention is described in more detail based on the accompanying preferred embodiments as follows.

2 and 3, the metal heating element 11 constituting the heating rod 10 of the present invention is a pair of series integrally integrated with the metal heating element 11 in the middle of the inner hole 12 as an embodiment It is configured to integrally include a heater mounting portion 20 having a heater coupling hole 22 between the thermal fragments 21 and 21 'and the pair of direct thermal members 21 and 21'.

In addition, the inner circumferential surface of the metal heating element 11 is provided between the sensor hole 31, a pair of inclined engaging portion 32 protruding to both sides of the sensor hole 31, and the pair of inclined engaging portion 32. It is comprised so that the sensor mounting part 30 which has the opening part 33 may be provided integrally.

The heater mounting part 20 and the sensor mounting part 30 are integrally formed by extruding the metal heating element 11.

Therefore, referring to FIG. 4, the heater coupling hole 22 is inserted into and fitted into the heater 13 having a flat shape.

In this case, the heater 13 is coupled to the gap pad 23 according to the type of the heater 13, and then the heater 13 is coupled to the heater coupling hole 22 or the heater 13 is inserted into the heater coupling hole 22 alone. Will be.

Referring to FIGS. 2 and 4 (a) and (b), in the case of the PTC heater in which the insulating film is covered on the outer surface, the heater has a relatively thin thickness and is inserted into the charging hole 231 of the gap pad 23 made of copper. (13) is coupled to be fitted to fit into the heater coupling hole (22).

At this time, when the heater 13 is fitted into the charging hole 231 of the gap pad 23, the heater 13 is inserted into the narrow hole 232 in the middle portion of the gap pad 23 so that the narrow hole 232. A pair of pressing pieces 233 in the upper and lower portions are inserted while being slightly opened.

Therefore, in a state in which the heater 13 is completely coupled to the gap pad 23, the pair of pressing pieces 233 pressurizes the heater 13, thereby fixing the heater 13 not to move.

Therefore, when the heater 13 coupled with the gap pad 23 is inserted into the heater coupling hole 22 and coupled as shown in FIG. 4B, the heater 13 is free from the gap pad 23 by the gap pad 23. To be combined.

On the other hand, in the case where the heater 13 employed in the heating rod 10 is a ceramic heater, only the heat dissipation grease is applied to the outer surface of the ceramic heater to be inserted into the heater coupling hole 22 as shown in FIG. It can be inserted and combined.

At this time, the side pads 23 'made of copper may be selectively attached to both sides of the heater 13 or to one side thereof so as to be fitted.

Since the gap pad 23 and the side pads 23 'are made of copper, heat transfer to the metal heating element 11 is made very good.

And the present invention may be coupled to be inserted into the heater coupling hole 22 by bringing the flat panel gap pad 23 "in close contact with the heater 13 surface as shown in FIG.

In this case, as shown in (a) of FIG. 5, the flat plate gap pad 23 ″ may be rolled in close contact with the outer surface of the heater 13 to be inserted into the heater coupling hole 22, or the upper surface of the heater 13 may be coupled. Each of the bottom and bottom plate gap pad (not shown) may be brought into close contact with each other to be inserted into the heater coupling hole 22.

In some cases, a flat plate gap pad (not shown) may be attached to only one of the top and bottom surfaces of the heater 13 to be inserted into the heater coupling hole 22.

In the present invention, the gap pad 23 or the flat gap pad 23 ″ is brought into close contact with the heater 13 and inserted into the heater coupling hole 22. The thickness of the heater 13 is only about 2-3 mm. In addition to the thickness, since the thickness of each heater 13 has a difference in thickness, the gap pad 23 or the flat gap pad 23 "is used to maximize the adhesiveness of the heater 13, and thus, the heater 13 The generated heat energy can be quickly transferred to the heat transfer pieces 21 and 21 '.

In addition, the gap pad 23 or the flat panel gap pad 23 ′ ′ shown in FIG. 5B may be exposed to one side of the metal heating element 11 so that the exposed portion can be easily held by the hand. In addition, since it is also convenient to withdraw later when the heating rod 10 is repaired, the assembly and separation of the heater 13 can be made very easy.

On the other hand, the sensor hole 31 of the sensor mounting portion 30 is mounted so that a plurality of temperature sensor 14 is inserted into the opening 33 and can be assembled very easily without a separate fixing means.

The temperature sensor detecting sensor 14 is prevented from being separated because the temperature sensor 14 is caught by the inclined catching part 32.

6 and 7 show another embodiment of the heater mounting portion according to the present invention.

Referring to FIG. 6, the heater mounting portion 20 ′ of another embodiment has respective heater coupling holes 22 on both sides by dividing the pair of direct heat pieces 21 and 21 ′ shown in one embodiment into two equal parts. It is configured to.

At this time, the front end portions 21a of the heat directing pieces 21 and 21 'which are opposed to each other are inclined inward to pressurize the heater 14 fitted into the heater coupling hole 22 so that the heater mounting portion 20' It was made up.

In this case, the heater mounting portion 20 'can be integrally formed when the metal heating element 11 is extruded.

Therefore, referring to FIG. 7, when the heater 13 is inserted to be inserted into the heater coupling hole 22, the front end portion 21a of the inclined heat sink 21, 21 ′ is inclined inward and is forced to open outward. (13) is fitted.

Therefore, in the state in which the heater 13 is completely engaged, the front end portion 21a of the heat transfer pieces 21 and 21 'acts to retract inward direction, and thus the front end portion 21a of the heat transfer pieces 21 and 21' is heated. By pressing (13), it is in a state of being firmly coupled.

Since the tip portion 21a of the direct heating pieces 21 and 21 'presses the heater 13 as described above, the heater 13 is closely contacted between the heater 13 and the direct heating pieces 21 and 21'. The heat transfer efficiency to the heat transfer pieces 21 and 21 'becomes high and plays a role of very good transfer.

On the other hand, the heating rod 10 of the present invention is in the glove 50 shown in Figure 2 in a portion other than the heater mounting portion 20 'and the sensor mounting portion 30, as shown in Figure 7 at the rear end A spring fixing hole 15 and a bushing assembly hole 15 'for assembling the glove hinge bushing 52 may be provided to mount the glove spring 51 serving to provide elasticity.

Therefore, the present invention, even if the heater mounting portion 20 ′ and the sensor mounting portion 30 are integrally provided in the metal heating element 11, other components such as the glove spring 51 or the glove hinge bushing 52 may generate heat from the rod 10. Since it can be mounted on the hair iron can be manufactured without any problem in manufacturing.

And the present invention, as shown in Figure 9, since the heater mounting portion 20 and the sensor mounting portion 30 is formed long in the longitudinal direction of the metal heating element 11 to the heat generating rod 10 by using the sensor mounting portion (30). Other parts to be assembled can be assembled simply and easily.

That is, when assembling the end cap fixing member 54 for fixing the end cap 53 to both sides of the heating rod 10 and the connecting member 56 for fixing the handle case 55 to be connected to the sensor hole ( 31) can be assembled by fastening the component assembly screw 34.

The component assembly screw 43 is made of steel while the metal heating element 11 is extruded from a metal having a high heat transfer coefficient such as aluminum, so that the component assembly screw 34 is screwed into the sensor hole 31. This makes it possible to smoothly tighten.

Therefore, the present invention inserts the heater 13 into the heater coupling hole 22 together with the gap pad 23 or the flat gap pad 23 ″ in constructing the heating rod 10 or the heater 13. Inserted into the heater coupling hole 22 alone and inserting the temperature sensor 14 connected to the temperature control unit 57 into the sensor hole 31 is simply completed, so assembling is much easier than before and the number of parts and As the assembly labor is reduced, productivity is improved and the cost of hair iron products is reduced.

In addition, the heat generating rod 10 of the present invention has the heat energy generated from the heater 13 by the heat generating element 21 and 21 'being integrally formed with the metal heating element 11 through the heat generating element 21, 21'. It is quickly delivered to the heating element (11).

Since all the heat energy of the heater 13 in the heater coupling hole 22 is transferred to the direct heating pieces 21 and 21 'immediately without escaping to the other place, all the heat energy with little heat energy loss from the heater 13 is generated. The heat transfer pieces 21 and 21 'are transferred to the heat transfer pieces 21 and 21' so that the heat transfer pieces 21 and 21 'are heated more quickly and move to the metal heating element 11.

In addition, since the heat energy generated from the surfaces of the direct heating pieces 21 and 21 'is directly transmitted to the inner surface of the metal heating element 11 through the inner holes 12 on both sides, the heat energy of the heater 13 is transferred to the surface of the metal heating element 11. It spreads more quickly and uniformly throughout.

That is, in the past, the heat energy of the heater was previously transferred through a separate heat transfer member or a heat transfer plate for the purpose of understanding, but the present invention is very fast because the heat energy of the heater 13 is directly transferred to the metal heating element 11 without any restriction. Heat is to be made uniformly.

Therefore, the present invention, when the electrical energy is initially applied to the heating rod 10 of the hair iron to perform the perm operation is rapidly risen to the desired perm temperature, the initial heating speed of the heating rod 10 proceeds quickly.

In addition, the present invention is very quick to restore the perm temperature at the time of perm operation.

For the sake of understanding, when the hair is wound on the heating rod 10 and subjected to permalysis, thermal energy is transferred to the hair, thereby lowering the surface temperature of the heating rod 10.

Therefore, first unwind the hair treated from the heating rod (10) and then the other hair is wound on the heating rod (10) to perm.

At this time, before winding the new hair to the heating rod 10, the surface temperature of the heating rod 10 is restored to a state in which the temperature is restored to the perm temperature. Since it takes a long time to be restored to rise to the perm temperature, the perm procedure takes a long time, or the perm operation was not performed until the perm temperature was recovered.

However, the present invention is because the heat energy of the heater 13 is quickly transferred to the metal heating element 11, so that the restoring force to the perm temperature is very fast in the process of permeation, so that the perm time can be greatly shortened and good permeation is made. .

In addition, the present invention is equipped with a temperature sensor 14 on the inner circumferential surface of the metal heating element 11, and as shown in Figure 8 embedded several temperature sensor 14 in the middle portion and both sides of the metal heating element (11). Since the hair is wound, the surface temperature of the heating rod 10 in direct contact with the hair and the set temperature of the temperature control unit 57 are almost invariable.

For the sake of understanding, the heating rod 10 has a different internal temperature with the heater 13 and the surface temperature at which the hair is in contact, and during the perm operation, the operator (beauty salon) adjusts the temperature control unit 57 to perform the procedure. It is set according to the perm temperature (set temperature). In the past, since the temperature sensor was installed inside the rear side of the heating rod, the surface temperature of the heating rod and the setting temperature of the temperature control part were severe, so it was a good perm treatment. It was difficult to do.

However, the present invention has almost no deviation between the surface temperature of the heating rod 10 and the set temperature of the temperature controller 57, so that the perm temperature control at the time of perm operation to set the permaper temperature differently and perform perma This can lead to easier permeation as well as good perm.

The present invention can be variously carried out by those of ordinary skill in the art in addition to the illustrated embodiment, it is obvious that it should be widely applied and protected without departing from the scope of the claims.
