[0049] The existing automatic curling iron includes a curling frame and a heat-conducting cylinder, the curling frame rotates around the heat-conducting cylinder, so that the hair is wound on the heat-conducting cylinder to curl the hair. However, the heat-conducting cylinder can only heat one side of the hair, resulting in a general curling effect, mainly the curling duration is short, which makes it difficult to meet the needs of the user.

[0050] In view of this, the utility model provides an automatic curling iron 100.

[0051] Please refer to Figures 1 to 3 In an embodiment of the utility model, the automatic curling iron 100 includes a handheld part 1, a first heating element 2, a curling frame 3 and a second heating element 4. The first heating element 2 is connected to one end of the handheld part 1; the curling frame 3 is installed on the periphery of the first heating element 2, and the curling frame 3 can rotate relative to the first heating element 2; the second heating element 4 is connected to the inner side of the curling frame 3, and the second heating element 4 and the first heating element 2 form a hair pressing gap 5.

[0052] It should be noted that the hand-held part 1 is the structure that the user holds the automatic curling iron 100 when using the automatic curling iron 100, and the hand-held part 1 is arranged in a substantially cylindrical shape, which is convenient for the user to hold. The first heating element 2 is a cylinder with heat conduction or heating function. The curling frame 3 is rotatably installed on the periphery of the first heating element 2, wherein the side wall of the curling frame 3 is provided with an entering hair port 33 extending along the axial direction of the curling iron, and the entering hair port 33 is arranged in a substantially U-shaped port. When the user enters the hair, the hair is entered from the entering hair port 33, so that the curling frame 3 rotates the hair onto the curling iron, wherein the hand-held part 1 is provided with a driving device for driving the curling frame 3 to rotate, and the driving device is used to drive the curling frame 3 to rotate around the first heating element 2. The driving mode of the driving device can be driven by a driving motor and the curling frame 3 is driven to rotate by a bearing, or the curling frame 3 is driven to rotate by a gear, which is not limited specifically here. Of course, the first heating element 2 can also rotate relative to the curling frame 3. The above two embodiments are optional embodiments of the present application.

[0053] Further, considering that the first heating element 2 can only heat one side of the hair bundle, in this embodiment, a second heating element 4 is also provided for heating the other side of the hair bundle, wherein the second heating element 4 is connected to the inner side of the curling frame 3, which can be that the second heating element 4 is screwed on the inner side of the curling frame 3, or the second heating element 4 is welded on the inner side of the curling frame 3, or the second heating element 4 is clamped on the inner wall of the curling frame 3, or the second heating element 4 is movably connected to the inner wall of the curling frame 3, which is not limited specifically here. Further, a pressing gap 5 is formed between the first heating element 2 and the second heating element 4, so that the hair can be heated by the first heating element 2 and the second heating element 4 in the pressing gap 5, wherein the pressing gap 5 is arranged in the range of 0.1mm to 0.5mm, that is, the pressing gap 5 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, or 0.5mm. The thickness of the pressing gap 5 is basically the same as the thickness of the hair bundle that needs to be pressed, which can keep the hair pressed in the pressing gap 5 by the first heating element 2 and the second heating element 4, so as to better realize the heating effect on the opposite sides of the hair, so that the curling effect of the hair after perming is better, and the duration of curling is longer.

[0054] The technical scheme of the utility model discloses that the second heating element 4 is arranged on the inner side of the curling frame 3, so that the pressing gap 5 is formed between the second heating element 4 and the first heating element 2. When the automatic curling iron 100 is used for perming, the hair is located in the pressing gap 5, and then the first heating element 2 and the second heating element 4 heat the opposite sides of the hair respectively, so that the hair has a better curling effect, and the curling maintenance time of the hair is increased, which meets the curling demand of the user.

[0055] In an embodiment, please refer to Figure 3 andFigure 4 The interval of the pressing interval 5 is adjustable.

[0056] Specifically, considering that the hair bundle diameter of different users is different, and the thickness of the hair put in each time is also different, in order to make the hair be pressed in the pressing interval 5, the interval of the pressing interval 5 is set to be adjustable in this embodiment, specifically, when the hair exerts pressure on the second heating element 4, the second heating element 4 has a tendency to move away from the first heating element 2, or the second heating element 4 has a tendency to deform away from the first heating element 2; or when the hair exerts pressure on the first heating element 2, the first heating element 2 has a tendency to deform away from the second heating element 4. The above are optional embodiments of the adjustable interval of the pressing interval 5, which are not specifically limited here.

[0057] Further, in this embodiment, please refer to Figures 3 to 5 The second heating element 4 is movably connected to the inner side of the curling frame 3, so that the second heating element 4 can move in the direction of approaching and moving away from the first heating element 2.

[0058] According to the above embodiment, the interval of the pressing interval 5 is set to be adjustable, and the specific adjustment mode of the pressing interval 5 is further limited in this embodiment. The second heating element 4 is movably connected to the inner side of the curling frame 3, and the specific connection mode between the second heating element 4 and the inner side of the curling frame 3 can be sliding connection. The second heating element 4 can slide along the slide or guide rail of the curling frame 3 in the direction of approaching and moving away from the first heating element 2 through a sliding mechanism (such as a sliding block, a roller, etc.). The second heating element 4 and the inner side of the curling frame 3 can also be connected through a hinge or a similar rotating connecting piece, and the pressing interval 5 can be changed by adjusting the rotating angle of the hinge. In addition, the second heating element 4 and the curling frame 3 can be connected through telescopic connection, such as through a telescopic rod, a telescopic spring, etc. to form a connection between the second heating element 4 and the inner side of the curling frame 3. The second heating element 4 and the curling frame 3 can also be connected through magnetic attraction connection, a screw adjustment mechanism, etc.

[0059] More specifically, in this embodiment, please continue to refer to Figures 3 to 5 The second heating element 4 is elastically connected to the curling frame 3.

[0060] It should be noted that, considering the cost and the limitation of installation space, the elastic connection is formed between the second heating element 4 and the curling rod 3, which can be that the second heating element 4 is compressed and then released, or the second heating element 4 is connected with the curling rod 3 through the elastic spring, and the above manners are optional embodiments of the present embodiment. The elastic connection of the second heating element 4 to the curling rod 3 can effectively save the installation space of the movable connection between the second heating element 4 and the curling rod 3, and reduce the installation steps between the second heating element 4 and the curling rod 3.

[0061] In an embodiment, referring to Figure 5 and Figure 6 , the inside of the curling rod 3 is provided with a mounting groove 31, and the second heating element 4 is at least partially mounted in the mounting groove 31.

[0062] It can be understood that, in order to make the connection relationship between the second heating element 4 and the curling rod 3 more stable, the inside of the curling rod 3 is provided with a mounting groove 31, and the second heating element 4 is at least partially mounted in the mounting groove 31, so that the second heating element 4 will not deviate from the installation position in the process of elastic expansion and recovery. The mounting groove 31 has a groove opening 311 and a groove bottom 312. Considering that the second heating element 4 needs to be tightly matched with the hair bundle, the second heating element 4 partially protrudes from the groove opening 311 of the mounting groove 31, so that the second heating element 4 and the hair bundle form a better tight compression relationship.

[0063] It should be noted that the mounting groove 31 can be a groove body directly recessed on the curling rod 3, or a groove body enclosed by at least two protruding partitions 36. In the present embodiment, the groove bottom 312 of the mounting groove 31 is recessed in the inner wall of the curling rod 3 around the mounting groove 31, and the mounting groove 31 is enclosed by the two protruding partitions 36, thereby forming the mounting groove 31.

[0064] In an embodiment, referring to Figure 4 , Figure 7 and Figure 8 , the second heating element 4 includes a heat source 41 and a hair pressing structure 42, the periphery of the mounting groove 31 is provided with a baffle 32, an elastic element 43 is arranged between one side of the hair pressing structure 42 and the groove bottom 312 of the mounting groove 31, and the opposite side of the hair pressing structure 42 abuts against the baffle 32.

[0065] Specifically, considering that in order to ensure that the second heating element 4 exerts a certain pressure on the hair, that is, the second heating element 4 has a tendency to elastically recover towards the first heating element 2, so that the second heating element 4 can exert pressure towards the hair, and in order to ensure that the second heating element 4 has a certain pressure while restricting the relative position of the second heating element 4, a baffle 32 is provided around the mounting groove 31. The baffle 32 can be set inside the mounting groove 31, or at the groove opening 311 of the mounting groove 31, or outside the mounting groove 31, without being specifically limited here. The second heating element 4 includes a heat source 41 and a hair pressing structure 42, wherein the heat source 41 is used for heating, and the hair pressing structure 42 directly presses the hair bundle, so the hair pressing structure 42 should have a good heat conduction effect, so that the hair pressing structure 42 can directly perm the hair.

[0066] In this embodiment, an elastic element 43 is provided between one side of the pressure-generating structure 42 and the bottom 312 of the mounting groove 31. Since the elastic element 43 has elastic potential energy, the other side of the pressure-generating structure 42 is pressed against the baffle 32, thereby limiting the relative position of the second heating element 4.

[0067] In one embodiment, please continue to refer to Figure 4 , Figure 7 and Figure 8 The pressing structure 42 includes a bracket 421 and a limiting member 422 connected to each other. The bracket 421 is provided with a receiving groove 421a. The heat source 41 is installed in the receiving groove 421a. The limiting member 422 is provided at both ends of the receiving groove 421a. The pressing structure 42 abuts against the two corresponding baffles 32 through the two limiting members 422 respectively.

[0068] Understandably, considering the need to adjust the distance between the elastic element 43 and the pressing structure 42, thereby ensuring a stable elastic connection and providing sufficient elastic potential energy, the pressing structure 42 is configured to include a support 421 and a limiting element 422. The support 421 and the limiting element 422 are fixedly connected, which can be by screwing, snap-fitting, or pressing; no specific limitation is made here. The elastic element 43 can be a sponge, a spring, or other elastic element 43 with elastic compression and elastic recovery functions. In this embodiment, to ensure a more stable connection and elastic recovery effect, the elastic element 43 is configured as a spring.

[0069] The support 421 is mainly used for pressing the hair strands, and a receiving groove 421a is formed in the support 421, which is mainly used for accommodating the heat source 41, and is also used for accommodating the limiting member 422. Two limiting members 422 are respectively arranged at opposite ends of the receiving groove 421a, and the two limiting members 422 are respectively abutted on the corresponding two baffles 32 by the two elastic members 43, so as to ensure that the elastic extension and contraction process of the hair pressing structure 42 is relatively stable.

[0070] In an embodiment, referring to Figure 7 and Figure 9 , the limiting member 422 comprises a fixed portion 422a and a limiting table 422b connected with each other. The fixed portion 422a is installed in the receiving groove 421a, and the limiting table 422b at the opposite ends of the receiving groove 421a respectively protrudes from the opposite ends of the support 421. The limiting member 422 is abutted on the baffle 32 through the limiting table 422b.

[0071] It should be noted that the limiting member 422 comprises a fixed portion 422a and a limiting table 422b connected with each other. The fixed portion 422a is installed in the receiving groove 421a, and the limiting member 422 forms a fixed connection relationship between the fixed portion 422a and the support 421. The specific connection relationship can be screwing, clamping or pressing, which is not limited here. The limiting table 422b protrudes from the opposite ends of the support 421, and then the limiting table 422b is abutted on the baffle 32, so that the limiting cooperation between the limiting member 422 and the baffle 32 does not interfere with the hair pressing function of the support 421, and the design saves the installation space.

[0072] In an embodiment, referring to Figure 7 and Figure 9 , the limiting member 422 is provided with a positioning table 422c protruding from one side of the bottom 312 of the mounting groove 31. The elastic member 43 is partially sleeved on the positioning table 422c, and the outer diameter of the elastic member 43 gradually increases from the positioning table 422c to the bottom 312 of the mounting groove 31.

[0073] Specifically, the limiting member 422 is provided with a positioning table 422c protruding from one side of the bottom 312 of the mounting groove 31. The positioning table 422c is used for positioning and limiting the setting position of the elastic member 43. Further, in order to prevent the elastic member 43 from deforming due to uneven stress during compression and recovery, the outer diameter of the elastic member 43 gradually increases from the positioning table 422c to the bottom 312 of the mounting groove 31, so that the structure of the elastic member 43 is more stable, and the elastic member 43 is not easy to move or deform irreversibly during compression and recovery.

[0074] In an embodiment, referring to Figure 8The bracket 421 is provided with a concave arc surface 421b facing the surface of the first heating element 2.

[0075] Specifically, in view of the fact that the first heating element 2 is provided in a cylindrical shape, in order to enable the first heating element 2 and the second heating element 4 to have a clamping effect on the hair strand, it is necessary to keep the distance of the pressing interval 5 substantially constant, and therefore the bracket 421 is provided with a concave arc surface 421b facing the surface of the first heating element 2, so that the surface of the first heating element 2 can be adapted to the shape of the first heating element 2.

[0076] In an embodiment, as shown in Figure 3 , Figure 4 and Figure 8 , the radius of the concave arc surface 421b is greater than the radius of the first heating element 2.

[0077] Specifically, in view of the fact that the curling rod 3 is provided outside the first heating element 2, and the second heating element 4 is provided on the curling rod 3, and the second heating element 4 is also located outside the first heating element 2, in order to keep the distance between the concave arc surface 421b of the bracket 421 and the first heating element 2 constant, the radius of the concave arc surface 421b is greater than the radius of the first heating element 2.

[0078] In an embodiment, as shown in Figure 7 and Figure 8 , the bracket 421 is provided with an opening 421c facing the bottom 312 of the mounting groove 31.

[0079] It should be noted that, in view of the fact that the forming step of the second heating element 4 is to install the heat source 41 into the accommodation groove 421a, and then install the two limiting members 422 into the two ends of the accommodation groove 421a, and then punch the bracket 421 to press the heat source 41 and the limiting members 422 into the accommodation groove 421a, respectively, the opening 421c is provided on the bracket 421 to facilitate the deformation of the bracket 421 during the punching process, so as to fix the limiting members 422 and the heat source 41.

[0080] In an embodiment, as shown in Figure 7 and Figure 8 , the material of the bracket 421 is metal.

[0081] Specifically, the material of the bracket 421 needs to have good heat conduction performance, and therefore the material of the bracket 421 is metal, more specifically, the material of the bracket 421 can be copper, aluminum or iron, and in the present embodiment, in view of the cost and corrosion resistance, the material of the bracket 421 is aluminum or an aluminum alloy.

[0082] In an embodiment, as shown in Figure 7 , Figure 12 ,Figure 13 and Figure 14 The heat source 41 leads an electric connection line 411 towards the handheld part 1, and the handheld part 1 is provided with a control module 6, and the electric connection line 411 is connected to the control module 6.

[0083] It can be understood that the heat source 41 is heated by power supply, and the material of the heat source 41 is PTC material, which is a thermistor and can quickly heat after power supply, so as to heat conduct the heat to the support 421 and heat the hair. The heat source 41 leads the electric connection line 411 on the side close to the handheld part 1, and the handheld part 1 is provided with the control module 6, and the electric connection line 411 is connected to the control module 6, and the control module 6 controls the heating and disconnection of the second heating element 4. The handheld part 1 can be provided with a battery, that is, the automatic curling iron 100 can also be used without being plugged in. Of course, the handheld part 1 can also not be provided with a battery, that is, the automatic curling iron 100 can only be used when plugged in, which is not limited specifically here.
