Set to hold the hair directly. In the present embodiment, the outer shells of the first splint 1 and the second splint 2 are all arranged in a circular arc surface, so that the curling iron has the functions of straight hair and curling hair at the same time. In order to ensure that all the hair can pass between the two splints during the perm process, the present solution is provided between the first heating plate 7 and the second heating plate 8 when the first clamping plate 1 and the second clamping plate 2 are in the closed state. A reserved gap 12 having a width of 0.06 mm to 0.12 mm.

It should be noted that the closed state of the first clamping plate 1 and the second clamping plate 2 described herein refers to the minimum angle between the two clamping plates when the two clamping plates are not opened, and the two heating plates are in this state. The distance is the smallest.

Specifically, during use, when the number of hairs between the first heating plate 7 and the second heating plate 8 is small, the two clamping plates are close to the closed state, since 0.06 mm to 0.12 mm is provided between the two heating plates. The gap of 12 is reserved, and the diameter of the human hair is about 0.08 mm, that is, when the two splints are closed, a small amount of hair between the two heating plates is not tightly clamped, which greatly reduces the clip on the hair when the splint is closed. With the tightening force, the hair can smoothly pass through the reserved gap 12, thereby preventing a small amount of hair from being pinched when the clamping force of the splint is too large, thereby avoiding damage to the hair.

It should be noted that the first heat generating plate 7 and the second heat generating plate 8 in the present embodiment may form a reserved gap 12 by various structural forms, for example, convex or convex portions are provided on both side edges of the two heat generating plates. Further, a convex structure or the like for supporting the first heat generating plate 7 and the second heat generating plate 8 is provided at other portions of the first and second plates 1 and 2. Preferably, the solution selects the second solution described above. Specifically, in the present solution, the first clamping plate 1 is hinged to the second clamping plate 2 by an elastic hinge, which is different from the prior art. The elastic hinges are similar. In order to support the two heating plates, the solution is further provided with a limiting block 14 for limiting the relative rotation of the first clamping plate 1 and the second clamping plate 2, and the second clamping plate 2 is disposed corresponding to the limiting block 14. The limit step 15 is as shown in FIG. Specifically, the elastic hinge includes a central shaft 13, a pressure lever 16 and a torsion spring 6, and the first clamping plate 1 is coupled to the central shaft 13 via a lever arm of the pressure lever 16 and rotatable about the central shaft 13, and the other of the pressure lever 16 The lever arm acts on the torsion spring 6, so that the spring force of the torsion spring 6 can be transmitted to the first jaw 1 through the pressure lever 16, thereby clamping the first jaw 1 and the second jaw 2. In the embodiment, the limiting block 14 is disposed on the pressure lever 16, and the limiting step 15 is disposed inside the second clamping plate 2. By setting the limiting block 14 and the limiting step 15, the minimum angle between the first clamping plate 1 and the second clamping plate 2 can be limited, thereby avoiding that the two heating plates are directly brought into contact with each other, that is, a reserved gap is formed. 12.

Since the elastic hinge often performs the opening and closing action, the limit block 14 may be worn after being used for a long time. In order to ensure that the reserved gap 12 maintains a certain width, the present embodiment adopts other structures for the second positioning support. Preferably, the present solution is provided with a supporting protrusion 11 at the end of the first clamping plate 1 and the end of the second clamping plate 2, and the two supporting protrusions 11 abut each other, that is, when the first clamping plate 1 and the first When the two clamping plates 2 are clamped together, the two supporting protrusions 11 are also pressed and contacted together, so that the other ends of the two heating plates are also supported to ensure that the reserved gap 12 does not become narrow or disappear, as shown in the figure. 3 is shown. More preferably, the support protrusions 11 in the present embodiment are designed as spherical protrusions, which reduces the contact area of the support protrusions 11, so that It is possible to prevent the hair from being pinched between the two support projections 11 when the hair is held by the perm, ensuring that the hair can be smoothly withdrawn from between the two support projections.

When the first splint 1 and the second splint 2 hold more thick hair, it is necessary to spread the hair between the two heating plates as much as possible so that the hair thickness is uniform, and the hair is evenly heated and in the two heating plates. Smooth sliding between. Preferably, the present solution is provided with a pressure spring 5 between the first heating plate 7 and the outer casing of the first clamping plate 1 (ie, the first outer casing 9), and the outer casing of the second clamping plate 2 (ie, the second second heating plate 8) A pressure spring 5 is also disposed between the outer casings 10). The pressure springs 5 are arranged to enable the two heat-generating plates to float up and down within a certain range between the two splints, that is, when the two splints hold more thick hair or When the hair is unevenly distributed, the user can easily widen the gap between the two heating plates by overcoming the pressure of the pressure spring 5, thereby dispersing and flattening the hair without further effort. A splint 1 and a second splint 2 rearrange the hair.

In order to further optimize the user's feeling of use, preferably, two pressure springs 5 are disposed between the first heat generating plate 7 and the outer casing of the first clamping plate, and two outer heating plates 8 and the outer casing of the second clamping plate are also provided. A pressure spring 5, each of which can apply a spring force ranging from 25 gram to 70 gram force (converted to a Newtonian force of 0.245 N to 0.686 N). That is to say, the elastic force that can be applied to each heating plate is 50 gram-140 gram force (0.49N~1.372N). This embodiment of the embodiment proves the elastic force range through experiments, which makes it easier for the user to tidy up the heating plate. Between the hair, therefore, the hair damage caused by vigorous pulling does not occur.

Because the curling device of the present invention uses an elastic hinge to fix the first clip The plate 1 and the second plate 2, therefore, when the two plates are opened, the user needs to manually overcome the elastic force of the torsion spring 6 to open the plate, and the solution is provided in the first plate 1 for the first plate 1 and the second The plywood 2 has an open handle 3. In order to make it easy for the user to open the splint and avoid the pain of the finger after frequent use by the user, preferably, the solution sets the opening and closing pressure range of the pressure cap 3 to 1.8 lbf to 3.8 lb. (in terms of Newton force, 8N~16.89) N) between.

It should be noted that the solution can adjust the opening and closing pressure of the pressing handle 3 in various ways, for example, by adjusting the spring coefficient of the torsion spring 6 or the material, size, etc., or by changing the distance of the pressing handle 3 from the central axis 13. By changing the distance between the torsion spring 6 and the central axis 13, etc., those skilled in the art can select different ways to achieve pressure adjustment according to specific needs.

Since the heating plate can reach a high temperature of 180 to 200 ° C during the working process, the heating plate can transfer heat to the outer casing of the clamping plate. When the temperature of the outer casing is too high, there is a hidden danger of scalding the user's skin. In order to solve this problem, preferably, the present embodiment is provided with a plurality of heat-dissipating holes 17 on the surface of the support protrusion 11. Specifically, the heat-dissipating holes 17 can communicate with the inner cavity of the splint, and heat generated by the heat-generating plate can be dissipated from the heat-dissipating holes 17, thereby reducing heat transferred to the outer casing, thereby lowering the temperature of the outer casing.

In order to further improve the heat dissipation efficiency, preferably, the solution may also be provided with a small heat dissipation fan in the inner cavity of the splint to effectively dissipate heat from the inner cavity of the splint.

Since the curling device in the present embodiment significantly reduces the temperature of the outer casing, according to the principle of "hot pressing and cold setting", the inside of the curling iron is subjected to high-temperature blanching, and the outer casing is cold-set, so that even if the shaped water is not used It also allows the hair to be well-set, saving costs and reducing damage to the customer's hair or scalp.

When the temperature of the outer casing is high, in order to avoid direct contact with the skin of the user, preferably, the first outer casing 9 and the second outer casing 10 are coated with a thermochromic paint, and when the temperature of the thermochromic paint reaches a preset value, The color of the outer casing will change to achieve a warning to the user and avoid direct contact with the user.

In addition, since most of the hair that is heated by the curling iron is wet hair, the temperature of the heat-generating plate is high during the perming process, and the water on the hair is heated to a high-temperature water vapor, which also increases heat conduction to the outer casing, in order to avoid this. Problem, preferably, in the present embodiment, the first heat generating plate 7 and/or the second heat generating plate 8 are provided with grooves for discharging high temperature water vapor. Specifically, the grooves may be designed as V arranged along the length of the heat generating plate. Structures such as groove or U-shaped groove. In use, high temperature water vapor can be vented to the air along the groove, avoiding retention in the splint and transferring heat to the outer casing, thereby reducing the temperature of the outer casing.

It can be seen from the specific description of the solution of the above embodiments that the hair curler provided by the present invention is not easy to break the hair during use, and can make all the hair pass smoothly between the splints, and the thermochromic paint of the splint shell and the heat-dissipating hole 17 and the like. The structure can lower the temperature of the outer casing or give the user a hint to avoid scalding the user's skin and greatly improve safety.

The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments are obvious to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention is not limited to the embodiments shown herein, but the broadest scope consistent with the principles and novel features disclosed herein.
