[0041] In one embodiment of the hair styling device of the present invention, please refer to Figures 1 to 4The hair styling device can achieve the effects of curling and straightening hair with different styles on hair, and can also achieve the effect of curling hair on shorter hair. Specifically, the hair styling device includes a lower clamping plate assembly 100, a middle clamping plate assembly 200, an upper clamping plate assembly 300 and a control circuit 400. The lower clamping plate assembly 100 and the upper clamping plate assembly 300 are respectively rotatably connected to the upper and lower sides of the fixed clamping plate 200. Therefore, the hair can be clamped by the lower clamping plate assembly 100 and the middle clamping plate assembly 200 to achieve the effect of curling hair. The hair can be clamped by the upper clamping plate assembly 300 and the middle clamping plate assembly 200 to achieve the effect of straightening hair or making the hair more fluffy. Specifically, the lower clamping plate assembly 100 and the upper clamping plate assembly 300 are respectively rotatably connected to the upper and lower sides of the middle clamping plate assembly 200. The middle clamping plate assembly 200 is provided with a second shaping clamping surface 221 and a third shaping clamping surface 222. The lower clamping plate assembly 100 is provided with a first shaping clamping surface 108, and the first shaping clamping surface 108 is used to clamp the hair with the second shaping clamping surface 221. The upper clamping plate assembly 300 is provided with a fourth shaping clamping surface 321, and the fourth shaping clamping surface 321 is used to clamp the hair with the third shaping clamping surface 222. The first shaping clamping surface 108 and the fourth shaping clamping surface 321 can be curved surfaces or planes with different shapes. Specifically, the first shaping clamping surface 108 can be the outer surface of a concave cavity formed by a downward depression, and the second shaping clamping surface 221 is an upwardly protruding arc surface that cooperates with the concave cavity surface. Or the first shaping clamping surface 108 is a downwardly protruding arc surface, and the second shaping clamping surface 221 is a concave cavity surface. Therefore, when the hair is heated by clamping the hair with the first shaping clamping surface 108 and the second shaping clamping surface 221, the hair can be bent to form a curling effect. By continuously clamping the hair at different positions, the hair can be made into a wave curl or egg curl effect, thereby presenting different styling effects. Since the lower clamping plate assembly 100 and the middle clamping plate assembly 200 are used to clamp the hair, the curling is achieved, and the operation is relatively more convenient. The third shaping clamping surface 222 and the fourth shaping clamping surface 321 can be mutually fitted clamping planes. Therefore, the hair can be clamped by the upper clamping plate assembly 300 and the middle clamping plate assembly 200 to achieve a straight hair effect. The third shaping clamping surface 222 and the fourth shaping clamping surface 321 can be mutually meshed serrated surfaces. Therefore, the hair can be clamped by the serrated surface, so that the hair can present a serrated bend, thereby making the hair more fluffy and achieving different styling effects. The third shaping clamping surface 222 and the fourth shaping clamping surface 321 can be mutually meshed concave and convex tooth surfaces, and the concave and convex teeth cooperate to achieve a straight hair effect.

Among them, the second heat-conducting clamp 223 and the third heat-conducting clamp 224 are respectively covered on the top and bottom of the cavity, and the second electric heating element 225 is provided on the inner side of the second heat-conducting clamp 223 and the third heat-conducting clamp 224; the bottom of the second heat-conducting clamp 223 protrudes downward to form a first shaping clamping surface 221, and the first shaping clamping surface 221 is a clamping surface for forming curls.

[0044] Please refer to Figure 1 , Figure 2 , Figure 4 , Fig.11 and Fig.12The upper clamping plate assembly 300 includes a top shell 310 and a third heating element 320. A connection position 203 is provided at one end of the connecting portion 201 closer to the second clamping element 220. Specifically, the connection position 203 is two downwardly recessed mounting grooves. One end of the top shell 310 is rotatably connected to the connection position 203. Specifically, the bottom side of one end of the top shell 310 extends downwardly to form two connecting plates 311, the two connecting plates 311 extend into the mounting grooves, and a pin is used to pass through the connection position 203 formed by the two connecting plates 311 and the two mounting grooves to realize the rotational connection between the top shell 310 and the middle shell 210. The third heating element 320 is arranged on the bottom side of the top shell 310, and a fourth shaping clamping surface 321 is provided at the bottom of the third heating element 320, and the fourth shaping clamping surface 321 is used to cooperate with the third shaping clamping surface 222 to clamp the hair. Specifically, the third heating element 320 includes a third electric heating element and a heat conducting plate. The heat conducting plate is disposed on the bottom side of the top shell 310, and the third electric heating element is disposed on the inner side of the heat conducting plate.

[0045] Please refer to Figure 2 and Fig. 9 The control circuit 400 is disposed in the handle portion 101 or the connection portion 201, and is connected to the first heating element 120, the second heating element, and the third heating element 320. Preferably, the control circuit 400 is disposed in the connection portion 201, so that the first heating element 120 and the third heating element 320 are conveniently connected to electricity.

[0046] The hair styling device of the above embodiment can rotate and open the upper clamping plate assembly 300 to a certain angle when straightening hair by pressing the top shell 310 in the upper clamping plate assembly 300. Therefore, the hair can be clamped by the upper clamping plate assembly 300 and the middle clamping plate assembly 200. Specifically, the hair is clamped between the third shaping clamping surface 222 and the fourth shaping clamping surface 321, and the third electric heating element and the second electric heating element 225 are energized to generate heat, so as to heat the hair and pull it along the direction of the hair tail, thereby achieving the effect of straightening hair. When curling hair, the lower clamping plate assembly 100 and the middle clamping plate assembly 200 are rotated to a certain angle to open the hair. Specifically, when clamping hair, the second shaping clamping surface 221 clamps the hair to the curling cavity 105, so that the hair is bent. Under the action of the first heating element 120 and the second heating element, the hair is heated and shaped. Since the hair is bent and clamped in the curling cavity, the curling effect is achieved. Since the curling is achieved by clamping, the operation is simple, and the hair can be clamped at any position, so that the curling effect can be achieved at any position of the hair, the curling effect is good, and diversified curling can be achieved. In addition, the hair styler of this embodiment can also achieve the curling effect for shorter hair. Specifically, by using the clamping method, the hair does not need to be wound, so shorter hair can also be clamped to achieve curling.

[0048] Furthermore, when the middle clamping plate assembly 200 is clamped with the lower clamping plate assembly 100, the connecting portion 201 and the handle portion 101 form a complete handle, so that when the hair straightening action is completed, it is convenient for the user to use.

[0049] Further, please refer to Figure 2 , Figure 3 , Figure 6 , Fig. 9 and Fig.12 A lock assembly 700 is also provided between the lower clamping plate assembly 100 and the middle clamping plate assembly 200. The lock assembly 700 is used to fix the lower clamping plate assembly 100 and the middle clamping plate assembly 200 as a whole when the lower clamping plate assembly 100 and the middle clamping plate assembly 200 are clamped together and the curling function is not used. Therefore, when the straightening function is used, the lower clamping plate assembly 100 and the middle clamping plate assembly 200 are prevented from being opened to affect the straightening effect of the user.

[0050] For further information, please refer to Figure 3 , Figure 6 , Fig. 9 and Fig.12The lock assembly 700 includes a sliding member 710, and the sliding member 710 is slidably connected to the handle portion 101 or the connecting portion 201. Preferably, the sliding member 710 is slidably connected in the handle portion 101, and the bottom end of the sliding member 710 extends with a toggle portion 711 extending out of the handle portion 101, and the top end is provided with a hook 712 extending out of the top side of the handle portion. The bottom side of the connecting portion 201 is provided with a through hole to avoid air, and the hook 712 extends into the through hole to avoid air. By pushing the toggle portion 711, the sliding member 710 is slid as a whole, so that the hook 712 is stuck on the inner side wall of the connecting portion 201 or is separated from the inner side wall of the connecting portion 201. Thereby, the lock assembly 700 can lock the middle clamping plate assembly 200 and the lower clamping plate assembly 100 as one. Specifically, a cavity is provided inside the connecting portion 201 and the handle portion 101, and is formed by a top wall and a bottom wall. The sliding member 710 is slidably connected in the handle portion 101. The bottom wall of the handle portion 101 is provided with a clearance groove 109, and the toggle portion 711 extends from the clearance groove 109. The hook 712 passes through the top wall of the handle portion 101 and the bottom wall of the connecting portion 201 and extends into the interior of the connecting portion 201. After the sliding member 710 slides, the hook portion of the hook 712 will be stuck on the top side of the bottom wall of the connecting portion 201, fixing the connecting portion 201 and the handle portion 101 as a whole.

[0051] Further, please refer to Fig.12 , the lock assembly 700 also includes a control switch 730, which is arranged in the handle portion 101. A push plate 720 is provided on one side of the sliding member 710, and the control switch 730 is pushed by the push plate 720 to switch the circuit, or the control switch 730 is turned on and off. Specifically, the control switch 730 is a toggle switch, and the push plate 720 is provided with a toggle groove 721. The toggle member of the control switch 730 extends into the toggle groove 721. And the heating element in the first heating element 120 and the second heating element that is in contact with the curling clamping surface is electrically connected to the control switch 730, so as to control the heating element in the first heating element 120 and the second heating element that is in contact with the curling clamping surface and the control switch 730 to turn on and off the power. Specifically, when the lock assembly 700 fixes the lower clamping plate assembly 100 and the middle clamping plate assembly 200, the control switch 730 controls the first heating element 120 and the second heating element to turn off the power. More specifically, the first electric heating element 122 in the first heating element 120 and the second electric heating element 225 in the second heating element that is attached to the inner side surface of the second heat-conducting clamping plate 223 are electrically connected to the control switch 730. When the sliding member 710 is pushed to slide, the push plate 720 pushes the control switch 730, so that when the hook 712 locks the middle clamping plate assembly 200 and the lower clamping plate assembly 100 as a whole, the control switch 730 cuts off the first electric heating element 122 in the first heating element 120 and the second electric heating element 225 in the second heating element that is attached to the inner side surface of the second heat-conducting clamping plate 223. In addition, the control switch 730 can also be a touch switch or a contact switch.

[0052] For further information, please refer to the Figure 8 , Fig.11 ; A groove 204 that is recessed downward is provided on the top side of the connecting portion 201. A pressing portion 312 is extended from one end of the top shell 310, and the upper clamping plate assembly 300 can be opened upward by pressing downwardly through the pressing portion 312. A stopper 313 that extends into the groove 204 is extended from the bottom side of the pressing portion 312. A locking tongue 740 is also slidably provided inside the connecting portion 201, and the top end of the sliding member 710 extends into the bottom side of the locking tongue 740; the locking tongue 740 is provided with a limiting member 741. When the sliding member 710 moves toward the first clamping member 102, the locking tongue 740 is pushed to slide, so that the limiting member 741 is limited at the bottom end of the stopper 313, and the control switch 730 controls the third heating member 320 to be powered off, and the first heating member 120 and the second heating member are powered on. Specifically, when the upper clamping plate assembly 300 and the middle clamping plate assembly 200 are used to clamp the hair, the sliding member 710 moves toward the direction of the handle, and the middle clamping plate assembly 200 and the lower clamping plate assembly 100 are fixed as one body through the hook 712, and the power of the heating element in the lower clamping plate assembly 100 is cut off, and the third electric heating element in the upper clamping plate 300 and the second electric heating element 225 located inside the third heat-conducting clamping plate 224 are turned on for heating. When the curling function is needed, the sliding member 710 slides to the other end, and the hook 712 releases the middle clamping plate assembly 200, and at the same time pushes the lock tongue 740 to slide, so that the limiter 741 of the lock tongue 740 extends into the bottom side of the stopper 313, which plays a limiting role on the upper clamping plate assembly 300 and prevents it from opening. In addition, the push plate 720 pushes the control switch 730 to switch, so that the first heating element and the second electric heating element 225 located inside the third heat-conducting clamping plate 224 are turned off. Preferably, a side wall of the groove 204 is provided with a clearance hole 205 , and when the limiting member needs to be limited at the bottom side of the stop member 313 , the limiting member 313 passes through the clearance hole 205 .

[0053] Further, please refer to Figure 2 and Figure 3 A baffle plate 206 is further provided in the connecting portion 201, and a third elastic member 750 is further provided between the baffle plate 206 and the lock tongue 740. The third elastic member 750 may be a compression spring. The third elastic member 750 is used to push the lock tongue 740 to move so that the limiting member 741 is limited at the bottom end of the stopper 313. In this embodiment, when the lock tongue 740 is pushed to the bottom end of the stopper 313, a certain elastic thrust can be applied to the lock tongue 740 by the third elastic member 750 to avoid the problem of the lock tongue 740 being loosened and retreating.

[0054] For further information, please refer to Fig.10The second heat conducting clamping plate 223 and the third heat conducting clamping plate 224 are an integrated structure of aluminum profiles, and the second heat conducting clamping plate 223 and the third heat conducting clamping plate 224 are connected by a rib plate. Therefore, the cost of the second heat conducting clamping plate 223 and the third heat conducting clamping plate 224 is reduced, and the installation of the second heat conducting clamping plate 223 and the third heat conducting clamping plate 224 is facilitated.

[0055] 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.
