Description

Technical Field

[0001] The utility model belongs to the technical field of hairdressing devices, and particularly relates to a hair straightener with a hair limiting structure. Background Art

[0002] Hair straighteners are currently the most commonly used hair styling tools. They are generally used to straighten hair and achieve the purpose of straight hair styling. Hair straighteners are generally composed of two clamping plates, and the two clamping plates are opened and closed by rotating.

[0003] For example, the Chinese patent document with publication number CN220675370U discloses a wide-plate hair straightener, comprising an upper plate shell and a lower plate shell, a transparent lampshade is installed on the upper surface of the upper plate shell, a temperature adjustment button is installed on one side of the upper plate shell, a power button is installed on the side of the upper plate shell close to the temperature adjustment button, a tail cover is provided at one end of the upper plate shell, an upper hair clamping aluminum plate assembly is fixedly connected to one end of the lower surface of the upper plate shell, an upper plate cover is fixedly connected to one end of the lower surface of the upper plate shell away from the upper hair clamping aluminum plate assembly, a lower hair clamping aluminum plate assembly is fixedly connected to one end of the upper surface of the lower plate shell, and the widths of the upper hair clamping aluminum plate assembly and the lower hair clamping aluminum plate assembly are both greater than the widths of the upper plate shell and the lower plate shell close to the tail cover.

[0004] For another example, the Chinese patent document with publication number CN116869266A discloses a hair straightener dryer and a styling method thereof, comprising: a hair straightening unit, comprising two arms hinged at one end, and two hair straightening plates opposite to each other are provided on the styling surfaces of the two arms; a hair straightening unit, comprising an air supply duct located in one arm and an air flow channel in the other arm, the air flow channel is opposite to the air outlet of the air supply duct and guides the air flow to flow out, and the air outlet of the air supply duct is located beside the two hair straightening plates; a control unit is provided in any arm, and the control unit controls the hair straightening unit and the hair straightening unit to work alone or together, and enter the hair straightening mode, the blowing mode or the hair straightening blowing mode. As a preferred embodiment, the air supply duct has an air inlet and an air outlet, and a motor and a first heating element are provided in the air supply duct, and the air flow is blown out from the air inlet through the motor and the heating element and out of the air outlet.

[0005] As can be seen from the above patent documents, hair straighteners are all clamped by two clamping plates, and then pulled along the hair tail direction to achieve heating and straightening of the hair. Because the two clamping arms are opened at an angle when clamping the hair, and after clamping the hair, the two clamping arms will still be at a certain angle, so there will be an opening at the free end of the two clamping arms. Therefore, when clamping and pulling the hair, some hair will slip out of the opening position. In particular, the hair straightener is provided with a blowing function, and the airflow blowing on the hair will cause the hair to further escape from the clamping of the clamping arms from the opening position. Utility Model Content

[0006] The utility model aims to provide a hair straightener with a hair limiting structure, so as to solve the problem that part of the hair may slide off from the opening positions of the two clamping arms when the hair is clamped by the existing hair straightener.

[0007] To achieve the above-mentioned purpose, an embodiment of the utility model provides a hair straightener with a hair limiting structure, comprising two clamping plates rotatably connected to each other, and clamping surfaces are provided on opposite sides of the two clamping plates; further comprising a limiting assembly, and the free end of at least one of the clamping plates is provided with the limiting assembly; the limiting assembly comprises an elastic member and a limiting pressure plate, the clamping surface is provided with a concave cavity, the limiting pressure plate is limited in the concave cavity and can move up and down, the elastic member is provided in the concave cavity and abuts against the limiting pressure plate, and is used to elastically support the limiting pressure plate so that the limiting pressure plate extends out of the concave cavity, and the top surface of the limiting pressure plate is not lower than the clamping surface.

[0008] Furthermore, the two clamps are both provided with the limiting assembly, and when the two clamps are clamped together, the two limiting pressure plates are in contact with each other, and the elastic member is squeezed.

[0009] Furthermore, two hooks extend from the bottom side of the limiting pressure plate, and undercuts are provided at the ends of the hooks; two through holes are provided on the bottom side of the concave cavity, and the hooks slidably extend into the through holes, and the undercuts are limited on the inner side walls of the through holes.

[0010] Furthermore, a positioning cavity is provided on the bottom side of the concave cavity, and a positioning ring is provided on the bottom side of the limiting pressure plate, and the positioning ring is limited in the positioning cavity.

[0011] Furthermore, the through hole is arranged on the inner wall of the positioning cavity, so that the through hole extends from the bottom of the concave cavity to the bottom of the positioning cavity and passes through the bottom of the positioning cavity; the hook is arranged on both sides of the positioning ring, and the undercut faces outward.

[0012] Furthermore, two first positioning columns are provided on the bottom side of the limiting pressure plate, two second positioning columns are provided on the bottom of the concave cavity, and the elastic member is a compression spring provided on the first positioning column and the second positioning column.

[0013] The above one or more technical solutions of the hair straightener with the hair limiting structure provided by the embodiment of the utility model have at least the following technical effects:

[0014] A limit assembly is provided at the free end of the clamping surface of the clamping plate. When the two clamping plates clamp the hair, the elastic member in the limit assembly supports the limit pressing plate, so that the limit pressing plate fits with the other limit pressing plate or the clamping surface, and a blocking position is formed between the free ends of the two clamping plates to prevent the clamped hair from being separated from between the two clamping plates. Even if the hair is blown, it can be ensured that the hair does not separate from the clamping position of the two clamping plates, ensuring that the clamped hair can be completely heated and straightened.

[0025] In one embodiment of the hair straightener of the utility model, please refer to Figures 1 to 5 The hair straightener with a hair limiting structure comprises two clamping plates 100 and a limiting assembly 200 which are rotatably connected to each other. A clamping surface 101 is provided on the opposite sides of the two clamping plates 100. A limiting assembly 200 is provided at the free end of at least one clamping plate 100. The limiting assembly 200 comprises an elastic member 210 and a limiting pressure plate 220. The clamping surface 101 is provided with a concave cavity 102, and the limiting pressure plate 200 is limited in the concave cavity 102, and the limiting pressure plate 200 can move up and down. The elastic member 210 is provided in the concave cavity 102 and abuts against the limiting pressure plate 220, and is used to elastically support the limiting pressure plate 220, so that the limiting pressure plate 220 extends out of the concave cavity 102, and the top surface of the limiting pressure plate 220 is not lower than the clamping surface 101. Since the limiting assembly 200 is arranged at the free end of the clamping surface 101 of the clamping plate 100, when the two clamping plates 100 clamp the hair mutually, the elastic member 210 in the limiting assembly 200 supports the limiting pressing plate 210, so that the limiting pressing plate 210 and the other limiting pressing plate 210 or the clamping surface 101 are mutually fitted, and a blocking position is formed between the free ends of the two clamping plates 100, so as to prevent the clamped hair from being separated from between the two clamping plates 100, and even if the hair is blown, it can be ensured that the hair does not separate from the clamping position of the two clamping plates 100, so as to ensure that the clamped hair can be completely heated and straightened.

[0026] Further, refer to Figure 2, both clamping plates 100 are provided with a limit assembly 200, and when the two clamping plates 100 are clamped together, the two limit pressing plates 210 are in contact with each other, and the elastic member 220 is squeezed. In this embodiment, when the two clamping plates 100 are clamped together, the two limit pressing plates 210 are also in contact with each other and are compressed into the concave cavity 102, so that the limit pressing plates 210 do not interfere with the clamping of the hair by the clamping plates 100.

[0027] For further information, please refer to Figure 4 and Figure 5 Two hooks 211 extend from the bottom side of the limiting pressure plate 210, and undercuts 212 are provided at the ends of the hooks 211. Two through holes 103 are provided at the bottom side of the concave cavity 102, and the hooks 211 slide into the through holes 103, and the undercuts 212 are limited at the inner side walls of the through holes 103. Thus, the limiting pressure plate 210 is limited in the concave cavity 102 and can move up and down.

[0028] For further information, please refer to Figure 4 and Figure 5 The bottom side of the concave cavity 102 is also provided with a positioning cavity 104, and the bottom side of the limiting pressure plate 210 is also provided with a positioning ring 213, and the positioning ring 213 is limited in the positioning cavity 104. The positioning cavity 104 cooperates with the positioning ring 213, thereby guiding and limiting the limiting pressure plate 210, and increasing stability.

[0029] For further information, please refer to Figure 5 , the through hole 102 is arranged on the inner side wall of the positioning cavity 104, so that the through hole 102 extends from the bottom of the cavity 102 to the bottom of the positioning cavity 104 and passes through the bottom of the positioning cavity 104. The hooks 211 are arranged on both sides of the positioning ring 213, and the undercuts 212 face outward. In the embodiment, the top and bottom of the through hole 102 are misaligned. When the limiting pressure plate 210 is assembled in the cavity 102, it is only necessary to tilt the limiting pressure plate 210 at a certain angle to extend the two hooks 211 into the corresponding through holes. This facilitates the assembly of the limiting pressure plate 210 into the cavity 102.

[0030] Further, refer to Figure 4 and Figure 5 Two first positioning columns 215 are provided on the bottom side of the limiting pressure plate 210 , two second positioning columns 105 are provided on the bottom of the concave cavity 102 , and the elastic member 220 is a compression spring sleeved on the first positioning columns 215 and the second positioning columns 105 .

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
