Description

Technical Field

[0001] This utility model belongs to the field of hair care product technology, and in particular relates to a hair curler. Background Technology

[0002] As a hair styling tool, home-use curling irons are widely used in daily life. The most common type is the curling iron, which consists of a handle and a heating element. Hair is wrapped around the heating element to achieve a curled effect. However, improper use of the heating element can easily burn the user.

[0003] Chinese patent document CN220403360U discloses a knob-type temperature-adjustable curling iron, including a grip, a connecting part, and a heating part. The connecting part is fixedly connected to the grip and the heating part at both ends, respectively. The grip includes a housing, within which a temperature-adjusting circuit board and a knob are disposed. The knob is electrically connected to the temperature-adjusting circuit board, and the housing has an adjustment hole through which the knob passes. The connecting part has a rotatably connected clip that fits against the heating part. The heating part includes a heating element and an internal heating unit, which is electrically connected to the temperature-adjusting circuit board. The heating temperature of the heating element is changed by rotating the knob, and the display shows the heating temperature in real time. The clip securely wraps hair around the heating element, preventing burns from excessively high temperatures.

[0004] In the aforementioned patent document's technical solution, the heating element's temperature is lowered in advance by rotating a knob after checking the temperature displayed on the monitor. However, to achieve a good curling effect, the heating element still needs a relatively high temperature. The heating element only has a clip to hold the hair in place, without any other protective components. This makes it easy to get burned when holding the curling iron close to the user. Furthermore, the heating element primarily heats the hair on the inner side in contact with the heating element, while the outer side of the hair is fixed by the clip, resulting in uneven heating between the inside and outside of the hair. Repeated operation is required to achieve the same styling effect, leading to poor curling results. Utility Model Content

[0005] The purpose of this invention is to provide a hair curler that solves the problem that existing hair curlers, which involve wrapping hair around a heating rod, are prone to burns and have poor curling results.

The fixing component 100 includes a first heating element 110 at the front end and a handle 120 at the rear end. The first heating element 110 has an upwardly protruding first protrusion 111 and a downwardly recessed first groove 112 on its top side to form a first heating surface 113. The movable component 200 includes a second heating element 210 at the front end and a connecting portion 220 at the rear end. The second heating element 210 has a second groove 212 that mates with the first protrusion 111 and a second protrusion 211 that mates with the first groove 112 on its bottom side to form a second heating surface 213. A curling space 230 is formed between the first heating surface 113 and the second heating surface 213 for clamping and curling hair. The handle 120 is hinged to the connecting portion 220.

[0036] Specifically, because the handle 120 is hinged to the connecting part 220, the fixed component 100 and the movable component 200 can be opened or closed. After opening the fixed component 100 and the movable component 200, the hair is placed on the first heating surface 113, and the curling iron is closed to bring the second heating surface 213 close to the first heating surface 113 and stabilize the hair within the curling space 230. This ensures that both sides of the hair are in full contact with the heating surface, guaranteeing even heating inside and outside the hair. The curling space also features protrusions and grooves to ensure the curl's setting effect and improve its quality. By opening and closing the curling iron to hold and heat the hair, a curling effect is achieved without winding the hair, avoiding tangles and poor setting.

[0037] Furthermore, the first heating element 110 includes a bottom shell 130, a first partition 140, an electric heating element 150, and a first heating surface 113.

Specifically, the first partition 140 separates the bottom shell 130 from the electric heating element 150, maintaining a certain distance between them to prevent excessive heat from the electric heating element 150 from being directly transferred to the bottom shell 130 and burning the user. At the same time, the electric heating element 150 approaches and heats the first heating surface 113, maintaining the temperature of the first heating surface 113.

[0038] Furthermore, the second heating element 210 includes a top shell 214, a third partition 215, a heating unit 216, and a second heating surface 213. The second heating surface 213 is installed on the bottom side of the top shell 214, the third partition 215 is positioned inside the second heating surface 213, and the heating unit 216 is installed between the second heating surface 213 and the third partition 215. Specifically, the third partition 215 separates the top shell 214 from the heating unit 216, maintaining a certain distance between them to prevent excessive heat from the heating unit 216 from being directly transferred to the top shell 214 and burning the user. At the same time, the heating unit 216 approaches and heats the second heating surface 213, maintaining the temperature of the second heating surface 213. The heating element 150 is located within the first protrusion 111 of the first heating surface, and the heating unit 216 is located within the second protrusion 211 of the second heating surface, preventing the heat in the curling space 230 from concentrating in one place and causing excessively high temperatures.

[0039] Furthermore, the first heating element 110 also includes a second partition 160. Limiting blocks 141 extend upwards from both ends of the first partition 140, and the bottom end of the second partition 160 is embedded in the limiting blocks 141, so that the outer surface of the second partition 160 fits against the bottom surface of the first protrusion 111. The electric heating element 150 is confined between the second partition 160 and the first partition 140. Specifically, the electric heating element 150 is confined within the second partition 160 and the first partition 140 to prevent the electric heating element 150 from shaking during use and to prevent the electric heating element 150 from directly contacting and heating the first heating surface 113, resulting in excessively high temperatures.

[0040] Furthermore, the first heating element 110 also includes a protective layer 170, which is installed between the bottom shell 130 and the first heating surface 113. Mounting plates 171 extend upwards from the front and rear ends of the protective layer 170 near the first protrusion 111, and the first protrusion 111 is confined within the two mounting plates 171. Limiting plates 172 extend upwards from the bottom of the protective layer 170 near the front and rear ends of the first groove 112, used to limit the first groove 112. Specifically, the protective layer 170 serves as heat insulation, further preventing heat from the electric heating element 150 in the first heating surface from being transferred to the bottom shell 130 and the handle 120, avoiding burns to the user and interference with the operation of other structures. Preferably, a protective layer is also provided between the second heating surface 213 of the second heating element and the top shell 214 to prevent heat from the electric heating unit 216 from being transferred to the outside of the top shell 214. Together, they control the heat within the curling space 230, ensuring the safe use of the hair curler.

[0041] Furthermore, a support plate 173 extends upward from the protective layer 170 located on the bottom side of the first partition 140 to support the first partition 140. A stiffener 174 extends upward from the protective layer 170 located on the bottom side of the first groove 112 to support the first groove 112. Specifically, the support plate 173 and the stiffener 174 enhance the support strength of the protective layer 170 for the first heating surface 113.

[0042] Furthermore, the protective layer 170 has locking blocks 175 at both ends, and the first heating surface 113 has corresponding mounting grooves 115 at both ends. The locking blocks 175 engage with the mounting grooves 115 to connect the protective layer 170 and the first heating surface 113. Specifically, by engaging the mounting grooves 115 with the locking blocks 175, the assembly of the protective layer 170 and the first heating surface 113 is facilitated.

[0043] Furthermore, a fixing plate 121 extends upward from both sides of the handle 120. A rotating shaft 122 is fixedly connected to the fixing plate 121 at both ends. The end of the connecting part 220 is rotatably connected to the rotating shaft 122. An extension part 221 extends downward from the end of the connecting part 220 toward the handle 120. The handle 120 and the connecting part 220 are hinged together. A housing 330 is also provided on the outer side. A through groove 320 is provided on one side of the housing 330. A locking member 310 is provided inside the housing 330.

A limiting part 312 is provided on the top side of the locking member 310. When the lever 311 is moved to the other end of the through groove 320, the limiting part 312 moves closer to and abuts against the bottom side of the extension part 221, so that the hair curler is in a closed state. Specifically, the lever 311 is located at one end of the through groove 320, and the limiting part 312 of the locking member does not contact the extension 221, so that the connecting part 220 and the handle 120 can rotate freely, causing the hair curler to open and close; when the lever 311 is moved to the other end of the through groove 320, the limiting part 312 abuts against the bottom side of the extension 221, restricting the rotation of the connecting part 220, locking the hair curler to keep it in a closed state, so that the hair is in a squeezed state, fully contacting the first heating surface 113 and the second heating surface 213, ensuring the curling effect, and locking and storing after curling.

[0044] Furthermore, a connecting plate 123 extends upward from the end of the handle 120, and a protruding horizontal bar 124 is provided on one side of the connecting plate 123. A locking member 310 extends downward and is provided with a hook 314, which slidably connects to the bottom end of the horizontal bar 124. Specifically, when the toggle block 311 is moved, the toggle block 311 slides in the through groove 320, causing the locking member 310 to slide on the connecting plate 123, and the hook 314 to slide on the horizontal bar 124, so that the locking member 310 moves stably on the handle 120.

[0045] Furthermore, a guide surface 313 is provided on the side of the limiting part 312 near the top. Specifically, the guide surface 313 serves a guiding function, facilitating the movement of the limiting part 312 to approach or move away from the releasing extension 221.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
