[0058] The utility model provides a hair curler.

[0059] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 In one embodiment of the present invention, the hair curler comprises:

[0060] The first arm portion 100 and the second arm portion 200, the first arm portion 100 and the second arm portion 200 each have a first end portion and a second end portion opposite to each other, and are connected together at their first end portions. Further, the first arm portion 100 and the second arm portion 200 are hinged, and a torsion spring structure (not shown) is provided at the hinge portion. Further, the first arm portion 100 and the second arm portion 200 each have a gripping section close to the hinge portion and a hair processing section away from the hinge portion. The inner wall of the first arm portion 100 is arranged facing the inner wall of the second arm portion 200. The inner wall of the first arm portion 100 is provided with a first heating element 300, and the first heating element 300 has a first contact surface 311. The inner wall of the second arm portion 200 is provided with a first heating element 300. Two heating elements 400, the second heating element 400 has a second contact surface 411, the first contact surface 311 is arranged facing the second contact surface 411, and a cavity 30 for receiving hair can be formed between the first contact surface 311 and the second contact surface 411; further, the first heating element 300 includes a first heat-conducting element 310 and a first heating element 320; the second heating element 400 includes a second heat-conducting element 410 and a second heating element 420, wherein the first heating element 320 is installed on the first heat-conducting element 310, and the second heating element 420 is installed on the second heat-conducting element 410; further, the first contact surface 311 is provided on the first heat-conducting element 310, and the second contact surface 411 is provided on the second heat-conducting element 410.

[0061] The first contact surface 311 and the second contact surface 411 should be understood as a complete surface. The resulting wavy cavity 30 is also complete, meaning there are no gaps within the cavity 30. Hair placed within the cavity 30 is then held between the first contact surface 311 and the second contact surface 411, preventing some hair from escaping from the cavity 30. This prevents some hair from escaping through the gaps within the cavity 30. Furthermore, in the closed state, when there is no hair between the first contact surface 311 and the second contact surface 411, at least portions of the first contact surface 311 and the second contact surface 411 abut against each other. In the open state, the first contact surface 311 and the second contact surface 411 are spaced apart, allowing the user to place hair between them.

[0062] The curling iron has an open state and a closed state. In the closed state, a wave-shaped cavity 30 is formed between the first contact surface 311 and the second contact surface 411. The cavity 30 has a crest portion 31 with an arc-shaped structure and trough portions 32 provided on both sides of the crest portion 31. The arc structure of the crest portion 31 is larger than the arc structure of the trough portion 32. Specifically, the crest portion 31 is provided between the two trough portions 32, and the arc structure located in the middle is larger than the arc structures on both sides. That is, the arc structure of the crest portion 31 located in the middle is larger than the arc structures on both sides of the trough portions 32. At this time, the wave shape formed by the hair placed in the cavity 30 can make the arc in the middle larger and the arcs on both sides relatively smaller, so that the hair formed by the curling iron of the same size can form a larger wave shape, thereby meeting the needs of some users and solving the technical problems existing in the prior art. However, the present design is not limited thereto. If two troughs 32 are provided on both sides of a peak 31 , the arc structure of the trough 32 located in the middle is larger than the arc structures of the troughs 32 located on both sides.

[0063] In one embodiment, the hair curler further comprises a heat-insulating gripping portion 500 , which is provided at the second end portion of the outer wall of the first arm portion 100 and the second arm portion 200 ;

[0064] The hair curler has an open state and a closed state; in the open state, the second ends of the first arm 100 and the second arm 200 are away from each other, and the first heating element 300 and the second heating element 400 can receive hair; in the closed state, the second ends of the first arm 100 and the second arm 200 are close to each other, and the first heating element 300 and the second heating element 400 can heat the hair; when in use, the user holds the first arm 100 and the second arm 200 of the hair curler and applies a certain force to the first arm 100 and the second arm 200, at which time the first arm 100 and the second arm 200 move closer to each other until they are closed (see Figure 1 ), when the force applied to the first arm 100 and the second arm 200 is removed, the first arm 100 and the second arm 200 are opened under the action of the torsion spring structure and are in an open state. Furthermore, when the curling iron is in the open state, the curling iron is opened at a certain angle and is not fully opened.

[0065] When the curling iron is in the closed state, pinching the heat-insulating gripping portion 500 on the first arm 100 and the second arm 200 can cause the first heating element 300 and the second heating element 400 to tend to move closer to each other. Furthermore, after the hair is placed between the first heating element 300 and the second heating element 400, the curling iron is closed. At this time, the first heating element 300 and the second heating element 400 can move closer to each other and squeeze the hair to heat it. At this time, the user can pinch the heat-insulating gripping portion 500 provided on the first arm 100 and the second arm 200. Since the heat-insulating gripping portion 500 is provided on the second end portion of the outer wall of the first arm 100 and the second arm 200, the second end of the first arm 100 and the second arm 200 can tend to move closer to each other. As a result, the first heating element 300 and the second heating element 400 tend to approach each other, thereby squeezing the hair located between the first heating element 300 and the second heating element 400, so that the hair is spread between the first heating element 300 and the second heating element 400, and is prevented from gathering together, thereby increasing the contact area between the hair and the first heating element 300 and the second heating element 400, and increasing the heating surface of the hair. At the same time, under the effect that the arc structure of the crest part 31 is larger than the arc structure of the trough part 32, the wavy styling effect of the hair is better.

[0066] In one embodiment, reference Figure 2 、 Figure 4 Furthermore, in order to reduce the heat transfer of the first heating element 300 to the outer wall of the first arm 100, the curling iron further includes a first heat insulation cover 600, which is provided at one end of the first heating element 300 close to the inner wall of the first arm 100. Furthermore, a first heat insulation cavity 610 is formed between the first heat insulation cover 600 and the inner wall of the first arm 100. In this embodiment, the first heat insulation cover 600 is configured to be made of a material with a low thermal conductivity, wherein the thermal conductivity is 0.005-0.6 W / (m·K). Under the effect of the material with a low thermal conductivity, the first heating element 300 can be prevented from being heated. 00 is transferred to the wall surface of the first arm 100, thereby achieving a heat insulation effect. At the same time, it can also prevent the first heat insulation cover 600 from absorbing too much heat of the first heating element 300, resulting in excessive heat loss of the first heating element 300, thereby achieving an effect of ensuring the thermal stability of the first heating element 300; and because the first heat insulation cover 600 and the inner wall of the first arm 100 form a first heat insulation cavity 610, under the action of the first heat insulation cavity 610, the heat of the first heat insulation cover 600 can be further reduced from being transmitted to the wall surface of the first arm 100, thereby achieving a better heat insulation effect.

[0067] In one embodiment, reference Figure 2 、 Figure 4In order to further improve the heat insulation effect of the curling iron, the curling iron further includes a second heat insulation cover 700. The second heat insulation cover 700 is provided at one end of the second heating element 400 close to the inner wall of the second arm 200. Furthermore, a second heat insulation cavity 710 is formed between the second heat insulation cover 700 and the inner wall of the second arm 200. In this embodiment, the second heat insulation cover 700 is configured with a material with low thermal conductivity. Under the effect of the material with low thermal conductivity, it can prevent the heat of the second heating element 400 from being transferred to the wall of the second arm 200. The surface of the second arm 200 has a heat insulation effect, and at the same time, it can also prevent the second heat insulation cover 700 from absorbing too much heat of the second heating element 400, resulting in too fast heat loss of the second heating element 400, thereby achieving two effects of ensuring the thermal stability of the second heating element 400; and because the second heat insulation cover 700 and the inner wall of the second arm 200 form a second heat insulation cavity 710, under the action of the second heat insulation cavity 710, the heat of the second heat insulation cover 700 can be further reduced from being transmitted to the wall surface of the second arm 200, thereby achieving a better heat insulation effect.

[0068] In one embodiment, the heat-insulating holding portion 500 is configured with a material with low thermal conductivity, wherein the thermal conductivity is 0.005-0.6W / (m·K). Specifically, an anti-scalding silicone block can be used. When the anti-scalding silicone block is used, the silicone block can increase the friction when the user holds it, making it easier for the user to hold it.

[0069] In one embodiment, reference Figure 2 、 Figure 4 The outer walls of the first arm 100 and the second arm 200 are both covered with a heat insulation layer 800. Furthermore, the heat insulation layer 800 is provided to further improve the heat insulation effect of the curling iron and prevent burns caused by the outer walls of the first arm 100 and the second arm 200 coming into contact with the human body during use of the curling iron.

[0070] In one embodiment, the thermal insulation layer 800 is configured with a material with low thermal conductivity, wherein the thermal conductivity is 0.005-0.6W / (m·K), and the material can be selected from PET material, PA material, etc. In this way, the thermal insulation layer 800 can be conveniently formed on the outer wall of the arm, which is convenient for processing and production, reduces production costs, and also has an anti-slip effect, making it convenient for users to hold the grip of the arm.

[0071] In one embodiment, reference Figure 1 、 Figure 3 、 Figure 5In order to facilitate the portability of the hair curler, the hair curler further includes a closing lock 900, which has a locked state and an unlocked state. When the hair curler is in the closed state, the closing lock 900 can switch between the locked state and the unlocked state; the closing lock 900 in the locked state can keep the hair curler in the closed state, that is, when the closing lock 900 is in the locked state, the hair curler can always be in the closed state. In this state, the space occupancy rate of the hair curler can be reduced, making the structure of the hair curler more compact; when the closing lock 900 is in the unlocked state, the hair curler can switch between the closed state and the open state, that is, when the closing lock 900 is in the unlocked state, the hair curler can be closed and opened, and the hair can be heated at this time.

[0072] In one embodiment, reference Figure 2 、 Figure 3 、 Figure 5 The closing lock 900 is provided at a side of the connection between the first arm 100 and the second arm 200 away from the second end, and the first arm 100 is fixed with a limiting portion 110 (see Figure 7 、 Figure 8) cooperates with the closing lock 900, and the limiting portion 110 is provided with an avoidance groove 111. Further, in this embodiment, the closing lock 900 can adopt the following structure, the closing lock 900 includes a lock body 910, a lock core 920 and a switch 930, the lock body 910 is installed at the first end of the second arm 200, the lock core 920 is slidably provided on the lock body 910, the lock body 910 is provided with a guide hole 911, the lock core 920 slides through the guide hole 911, the switch 930 is installed on the lock body 910, and is driven and connected to the lock core 920, the lock core 920 The lock core 920 has a first position and a second position set along the length direction of the hair curler; when the lock core 920 is in the first position, the lock core 920 abuts against the limiting portion 110 to keep the hair curler in a closed state, that is, the switch 930 drives the lock core 920 to move along the length direction of the hair curler so that the lock core 920 is in the first position. At this time, the lock core 920 abuts against the limiting portion 110 of the first arm 100. Since the closing lock 900 is provided at a position away from the second end of the connection between the first arm 100 and the second arm 200, the lock core 920 is in a closed state. When the lock core 920 is in the second position, the lock core 920 corresponds to the avoidance groove 111. When the curling iron switches from the closed state to the open state, the lock core 920 can be located in the avoidance groove 111. The switch 930 drives the lock core 920 to move along the length direction of the curling iron, so that the lock core 920 is in the second position. At this time, the lock core 920 does not abut against the limiting portion 110 of the first arm 100, and the curling iron can be opened under the action of the torsion spring structure. At this time, the second ends of the first arm 100 and the second arm 200 can tend to separate. At this time, the limiting portion 110 of the first arm 100 can move toward the lock core 920, so that the lock core 920 is located in the avoidance groove 111 of the limiting portion 110. After opening to a certain angle, the limiting portion 110 of the first arm 100 abuts against the second arm 200, preventing the curling iron from further opening. In this application, the limiting portion 110 of the first arm 100 has the function of limiting the angle at which the curling iron can be opened.

[0073] In one embodiment, reference Figure 5 、 Figure 6The lock core 920 can adopt the following structure: the lock core 920 includes a connected mounting rod 921 and an adjustment block 922, the switch member 930 is driven and connected to the mounting rod 921, the avoidance groove 111 cooperates with the mounting rod 921, and the adjustment block 922 has a first position and a second position set along the length direction of the hair curler. The switch member 930 drives the mounting rod 921, and the mounting rod 921 can drive the adjustment block 922 to move, so that the adjustment block 922 switches between the first position and the second position; when the adjustment block 922 is in the first position, the adjustment block 922 and the adjustment block 922 are in the same position. The first end of the first arm 100 abuts against a position away from the hinge to keep the curler in a closed state. At this time, the adjustment block 922 abuts against the position of the first end of the first arm 100 away from the hinge. Under the action of the adjustment block 922, the first arm 100 can flip around the hinge and cannot move away from the second arm 200. At this time, the curler remains in a closed state; when the adjustment block 922 is in the second position, the avoidance groove 111 corresponds to the mounting rod 921. When the curler switches from the closed state to the open state, the mounting rod 921 can be located in the avoidance groove 111.

[0074] In one embodiment, reference Figure 5 、 Figure 6 The switch member 930 includes a rotating ring 931, a driving plate 932, and a spiral track 933 provided on the driving plate 932. The mounting rod 921 is provided with a driven pin 923 corresponding to the spiral track 933, and the driven pin slides through the spiral track 933. Specifically, the lock body 910 is mounted on the first end of the second arm 200, and forms a cylindrical structure with the first end of the second arm 200. At this time, the driving plate 932 is attached to the outside of the lock body 910 and can slide on the outside of the lock body 910. The rotating ring 931 is rotatably mounted on the outside of the cylindrical structure and is driven by the driving plate 932. When the rotating ring 931 rotates on the outside of the cylindrical structure, it can drive the driving plate 932 to move outside the lock body 910. When the drive plate 932 slides on the outside of the lock body 910, the spiral track 933 provided on the drive plate 932 can drive the driven pin to move. As the rotating ring 931 rotates back and forth, the drive plate 932 slides back and forth on the outside of the lock body 910, and the spiral track 933 can drive the driven pin to move back and forth. Furthermore, the spiral line of the spiral track 933 extends along the length direction of the curler. In this way, when the spiral track 933 drives the driven pin to move back and forth, the driven pin can move back and forth along the length direction of the curler, thereby realizing the reciprocating movement of the mounting rod 921 and the adjustment block 922 along the length direction of the curler, thereby realizing the purpose of switching the adjustment block 922 back and forth between the first position and the second position.

[0075] In one embodiment, reference Figure 1The hair curler further includes a button 40, which is installed between the first arm 100 or the second arm 200. Specifically, the button 40 is installed on the inner wall of the first arm 100 or the second arm 200.
