Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to a hair curling iron. Background Technology

[0002] Cornrow perm is an internationally popular hairstyling technique that uses softening treatments and cornrow curlers to create a fluffy, natural wavy texture in the hair. This hairstyle requires the use of a perm tool.

[0003] A curling iron, also known as a hair straightener, is disclosed in utility model patent application number 202020073304.1. It includes an upper cover and a lower cover. The upper cover has a handle at its rear end, and the lower cover has a handle at its rear end. One end of the upper cover handle is hinged to one end of the lower cover handle. The upper cover has an aluminum plate on its inner front end, with an M-shaped cross-section and curling teeth on its surface. The lower cover has an aluminum plate on its inner front end, with a W-shaped cross-section and curling teeth on its surface. Heating elements are located inside both the upper and lower aluminum plates.

[0004] Existing hair curlers on the market, as described in the aforementioned patent, typically use staggered protruding curling teeth on the upper and lower aluminum plates. The upper and lower plates work together to clamp and hold the hair in place. The hair is then heated and styled using the temperatures of the aluminum plates and the curling teeth. However, because the ends of the curling teeth are far from the heating element, they require a longer preheating time to reach the preset curling temperature. When the curling teeth reach the desired temperature, the aluminum plate surface is also very hot, which can damage the hair, making it dry and frizzy. Furthermore, when using existing hair curlers, the hair between adjacent curling teeth adheres to the aluminum plate surface, further increasing hair damage. Summary of the Invention

[0005] This invention provides a hair curling iron that reduces damage to hair compared to existing hair curling irons.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A hair curling device, comprising:

[0008] First shell;

[0009] A second housing, one end of which is hinged to one end of the first housing;

[0010] The first clamping plate is located on the side of the first housing away from the hinge end, and the first clamping plate is located on the side of the first housing close to the second housing. The surface of the first clamping plate close to the second housing is provided with a plurality of curling teeth.

[0011] A first heating element is disposed inside the first housing for heating the first clamping plate;

[0012] The second clamping plate is located on the side of the second housing close to the first housing. The second clamping plate corresponds to the first clamping plate and has a plurality of holes that correspond one-to-one with the perming teeth.

[0013] A heating plate is disposed inside the second housing. There is a gap between the heating plate and the second clamping plate. When the first clamping plate and the second clamping plate approach each other, the curling teeth pass through the hole and abut against the heating plate.

[0014] The second heating element is located inside the second housing and is used to heat the heating plate.

[0015] Furthermore, the plurality of holes are divided into multiple groups of hole units, which are disposed on the second clamping plate and are equally spaced along the width direction of the second housing. The plurality of holes in each group of hole units are equally spaced along the length direction of the second housing, and the plurality of holes in adjacent hole units are staggered.

[0016] Furthermore, the heating plate has slots on both sides of the second housing in the width direction, and the two opposite sides of the second clamping plate have snap-fit ​​parts that engage with the slots.

[0017] Furthermore, the heating plate has a second receiving groove on the side away from the second clamping plate for accommodating the second heating element, and the opening of the second receiving groove has a limiting part for limiting the second heating element.

[0018] Furthermore, a second elastic element is provided inside the second housing. The second elastic element is located on the side of the second heating element away from the second clamping plate. When the second elastic element is in its natural state, the second elastic element abuts against the second heating element.

[0019] Furthermore, the first clamping plate has a first receiving groove on the side away from the second housing for accommodating the first heating element.

[0020] Furthermore, an NTC thermistor is provided in the first receiving tank.

[0021] Furthermore, a pressure plate is provided inside the first housing, and a first elastic member is provided between the pressure plate and the first heating element. When the first elastic member is in its natural state, both sides of the first elastic member abut against the pressure plate and the first heating element, respectively.

[0022] Furthermore, the first clamping plate is provided with a first plug on the side away from the hinge end of the first housing, and the second clamping plate is provided with a second plug on the side away from the hinge end of the second housing.

[0023] The beneficial effects of this utility model are:

[0024] The heating plate of this invention is located below the second clamping plate and there is a gap between the two. The second heating element heats the heating plate. When the temperature of the heating plate reaches the preset temperature, the temperature of the second clamping plate will be lower than the perming temperature. Since there are holes on the second clamping plate and no perming teeth are provided, when the first clamping plate and the second clamping plate clamp the hair, the hair located in the gap between the perming teeth will fall on the surface of the second clamping plate with a lower temperature and will not stick to the first clamping plate with a higher temperature. Thus, while achieving perming, damage to the hair is reduced. Attached Figure Description

Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] Example

[0032] like Figure 1-3 As shown, the present invention provides a hair curling device, which includes a first housing 10, a second housing 20, a first clamping plate 30, a second clamping plate 40, a first heating element 50, a second heating element 60, and a heating plate 70.

[0033] One end of the second housing 20 is hinged to one end of the first housing 10. A first clamping plate 30 is located on the side of the first housing 10 away from the hinged end, and is also located on the side of the first housing 10 closest to the second housing 20. The surface of the first clamping plate 30 closest to the second housing 20 has multiple perming teeth 301. A first heating element 50 is located inside the first housing 10 to heat the first clamping plate 30. A second clamping plate 40 is located on the side of the second housing 20 closest to the first housing 10, corresponding to the first clamping plate 30. The second clamping plate 40 has multiple holes 401 corresponding one-to-one with the perming teeth 301. A heating plate 70 is located inside the second housing 20, with a gap between the heating plate 70 and the second clamping plate 40. When the first clamping plate 30 and the second clamping plate 40 approach each other, the perming teeth 301 pass through the holes 401 and abut against the heating plate 70. A second heating element 60 is located inside the second housing 20 to heat the heating plate 70.

[0034] When using the hair curler of this utility model for perming, the first heating element 50 and the second heating element 60 preheat the first clamping plate 30 and the heating plate 70 respectively. When the temperature of the first clamping plate 30 and the temperature of the heating plate 70 reach the perming temperature, the perming teeth 301 of the first clamping plate 30 are facing down and the second clamping plate 40 is facing up. Then, the hair is placed between the first clamping plate 30 and the second clamping plate 40. By pressing the first housing 10 and the second housing 20, the first clamping plate 30 and the second clamping plate 40 are moved closer to each other. The perming teeth 301 on the first clamping plate 30 and the holes 401 on the second clamping plate 40 are adapted to clamp the hair. The perming teeth 301 on the first clamping plate 30 and the heating plate 70 work together to heat and shape the hair, thus achieving perming.

[0035] The heating plate 70 of this invention is located below the second clamping plate 40 and there is a gap between the two. The second heating element 60 heats the heating plate 70. When the temperature of the heating plate 70 reaches the preset temperature, the temperature of the second clamping plate 40 will be lower than the perming temperature. Since the second clamping plate 40 has holes 401 and no perming teeth 301 are provided, when the first clamping plate 30 and the second clamping plate 40 clamp the hair, the hair located in the gap of the perming teeth 301 will fall on the surface of the lower temperature second clamping plate 40 and will not stick to the higher temperature first clamping plate 30. Thus, while achieving perming, damage to the hair is reduced.

[0036] Furthermore, the multiple holes 401 are divided into multiple groups of holes 401 units. The multiple groups of holes 401 units are provided on the second clamping plate 40 and are equally spaced along the width direction of the second housing 20. The multiple holes 401 in each group of holes 401 units are equally spaced along the length direction of the second housing 20, and the multiple holes 401 in adjacent groups of holes 401 units are staggered.

[0037] Specifically, in this embodiment, the second clamping plate 40 is provided with three sets of hole 401 units, each set of hole 401 units including four holes 401, and the holes 401 of adjacent hole 401 units are staggered. The position and number of the perming teeth 301 on the first clamping plate 30 correspond to the holes 401 on the second clamping plate 40.

[0038] This invention allows for better perming of the cornrow perm hairstyle by arranging the holes 401 on the second clamping plate 40.

[0039] Furthermore, the heating plate 70 has slots 701 on both sides of the second housing 20 in the width direction, and the two opposite sides of the second clamping plate 40 have engaging parts 402 that engage with the slots 701. The above structure can position the heating plate 70 so that the heating plate 70 will not shift when the hair curler is in use.

[0040] Furthermore, the heating plate 70 has a second receiving groove 702 on the side away from the second clamping plate 40 for accommodating the second heating element 60, and the opening of the second receiving groove 702 has a limiting part 703 for limiting the second heating element 60. In this embodiment, the second heating element 60 is a PTC ceramic heating element. By providing the second receiving groove 702 and the limiting part 703, the second heating element 60 is kept in good contact with the heating plate 70, which can improve the heating stability of the second heating element 60 on the heating plate 70, thereby improving the working stability of the hair curler of this utility model.

[0041] Furthermore, a second elastic element 80 is provided inside the second housing 20. The second elastic element 80 is located on the side of the second heating element 60 away from the second clamping plate 40. When the second elastic element 80 is in its natural state, it abuts against the second heating element 60. By providing the second elastic element 80, the second heating element 60 can always be in close contact with the heating plate 70, thereby improving the heat conduction efficiency of the second heating element 60.

[0042] Furthermore, the first clamping plate 30 has a first receiving groove 101 on the side away from the second housing 20 for accommodating the first heating element 50. Placing the first heating element 50 in the first receiving groove 101 allows it to directly contact the first clamping plate 30, improving the heating efficiency of the first heating element 50 on the first clamping plate 30 and enabling the first clamping plate 30 to quickly reach the perming temperature. In this embodiment, the first heating element 50 is a PTC ceramic heating element.

[0043] Furthermore, an NTC thermistor 90 is provided inside the first receiving groove 101. This is used to monitor the temperature change of the first clamping plate 30, so that the first clamping plate 30 can be maintained at a constant operating temperature.

[0044] Furthermore, a pressure plate 91 is provided inside the first housing 10, and a first elastic member 92 is provided between the pressure plate 91 and the first heating element 50. When the first elastic member 92 is in its natural state, its two sides abut against the pressure plate 91 and the first heating element 50, respectively. The arrangement of the pressure plate 91 and the first elastic member 92 ensures that the first heating element 50 maintains close contact with the first clamping plate 30, improving the heating efficiency of the first heating element on the first clamping plate 30, thereby enabling the first clamping plate 30 to quickly reach the preset perming temperature.

[0045] Furthermore, a PCB board 93 is provided inside the first housing 10 on the side near the hinge end, and the PCB board 93 is electrically connected to the first heating element 50, the second heating element 60 and the NTC thermistor 90.

[0046] Furthermore, the PCB board 93 is electrically connected to an operation button 94, a power supply, and a temperature indicator light 95. The power supply is located at the hinge end of the first housing 10 and the second housing 20. The power supply is a power cable 97 connected to the hinge end of the first housing 10 and the second housing 20 through a female connector 96, allowing the power cable 97 to freely rotate along the female connector 96. The free rotation of the power cable 97 does not affect the normal power supply and makes the curling operation more convenient.

[0047] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
