[0037] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] Referring to Figures 1 to 7 , an embodiment of the present invention provides a dual-purpose hair straightening and curling device, comprising a main unit 10 and a curling head 20. The main unit 10 includes a main unit housing 101; the main unit housing 101 includes an upper housing 1011 and a lower housing 1012, which are fixedly connected. The main unit housing 101 forms a handle structure, and during use, the main unit housing 101 is grasped to perform the corresponding curling or straightening operation.

[0041] The curling head 20 is connected to the curling main unit 10. The curling head 20 is provided with a curling lever 201 and a heating channel 202. The heating channel 202 includes an upper channel 2021 and a lower channel 2022. A channel gap 2023 is provided between the upper channel 2021 and the lower channel 2022. An upper movable heating plate 20212 that can move up and down is provided at a position opposite to the upper channel 2021 and the lower channel 2022. The upper movable heating plate 20212 is used to clamp the hair in the channel gap 2023 when straightening the hair, and cooperate with the lower heating plate 20221 corresponding to the upper movable heating plate 20212 and the lower channel 2022 to heat and shape the hair. The curling lever 201 is driven by the curling main unit 10 to rotate so as to roll the hair into the outer surface of the heating channel 202 for heating and shaping when curling the hair. As shown in Figure 2, the bifurcated heating channel 202 allows for a hair straightening gap 2023 in the middle of the channel. For hair straightening, hair can be placed between the gap 2023, where it is heated by the upper and lower heating plates. By pulling the handle, the hair passes through the gap 2023 from the root to the tip, where it is heated sequentially by the upper and lower heating plates 20221, thereby straightening the hair. To better clamp and heat the hair, in this embodiment of the present invention, the hair straightening heating plate in the upper half of the channel 2021 is designed to be movable upward and downward. In the initial state, the upper movable heating plate 20212 is closed to the corresponding heating plate in the lower half of the channel 2022. When hair is placed from the end of the heating channel 202 into the hair channel slit 2023, the force exerted by the hair slightly lifts the upper movable heating plate 20212, allowing the hair to be placed in the hair channel slit 2023. The lower heating plate 20221 at the lower half of the hair channel 2022 can be an integral, fixed structure. This allows the upper movable heating plate 20212 and lower heating plate 20221, which can move up and down, to clamp the hair relative to each other, thereby providing better heating during hair straightening.

[0042] As shown in Figure 2, the outer side of the heating element 202 is also equipped with a curling lever 201. During curling, the curling lever 201 rotates under the control of the curling main unit 10, thereby moving the hair to the outer surface of the heating element 202. The outer surface of the heating element 202 heats and shapes the hair. This allows a single hair styling device to perform both straightening and curling operations, greatly facilitating user convenience. During use, the cylindrical heating element 202, with its internal gap and clamping structure, allows for both curling and straightening heating operations, thus achieving a two-in-one function of hair straightening and automatic curling, greatly facilitating user convenience.

[0043] Referring to Figures 3, 4, and 6, an upper heating plate return spring 20213 is disposed between the upper movable heating plate 20212 and the upper hair duct 2021. This return spring 20213 is used to provide a return force to the upper movable heating plate 20212, thereby clamping the hair within the hair duct slit 2023. As shown in Figure 6, two return springs are disposed above the upper movable heating plate 20212, located near each end of the upper movable heating plate 20212. This provides a more uniform and balanced force on the upper movable heating plate 20212. The other end of the return spring can contact the inner side of the top of the heating duct 202. In this way, the heating plate reset spring can provide a reset force for the upper movable heating plate 20212, and the upper movable heating plate 20212 can be pushed toward the lower half hair channel 2022 by the reset force, so that the hair can be clamped between the upper movable heating plate 20212 and the lower heating plate 20221 in cooperation with the lower heating plate 20221.

[0044] Referring to Figures 5 to 7 , mounting rails 20211 are provided on either side of the upper heat exchanger 2021, and mounting blocks 202121 are provided on either side of the upper movable heating plate 20212. The height of the mounting rails 20211 is greater than the thickness of the upper movable heating plate 20212, and the mounting blocks 202121 are mounted within the mounting rails 20211. As shown in Figure 5 , the upper heat exchanger 2021 is hollow. The cross-sectional areas of the inner walls of the upper heat exchanger 2021 are C-shaped, forming the mounting rails 20211. Mounting blocks 202121 are provided on either side of the upper movable heating plate 20212, and the mounting blocks 202121 on either side of the upper movable heating plate 20212 are respectively mounted within the mounting rails 20211. Since the height of the mounting rail 20211 is greater than the thickness of the upper movable heating plate 20212, the upper movable heating plate 20212 can move up and down within the height range of the mounting rail 20211. In this way, under the action of the upper heating plate return spring 20213, the upper movable heating plate 20212 and the lower heating plate 20221 can be in an initial state of elastic clamping.

[0045] 2 to 6 , the dual-purpose hair straightening and curling device further includes a clamping assembly 30, comprising a clamping button 301 and a push plate 302. The clamping button 301 is mounted on the main body housing 101; the push plate 302 is disposed within the upper hair channel 2021. An inclined groove 3021 is defined at the bottom of the push plate 302. A protrusion 202122 is defined at the contact point between the upper movable heating plate 20212 and the inclined groove 3021. One end of the push plate 302 abuts against the clamping button 301, allowing the push plate 302 to move away from the hair straightening device 10 under the control of the clamping button 301. This, in turn, drives the protrusion 202122 and the upper movable heating plate 20212 as a whole toward the lower hair channel 2022 via the inclined groove 3021, thereby clamping the hair within the hair channel gap 2023. As shown in Figures 3 and 6, the main body upper shell 1011 is provided with a button mounting position 10111, which is provided with a shaft through-hole 10112. A shaft can be provided in the shaft through-hole 10112. After the clamping button 301 is installed in the button mounting position 10111, it can rotate around the shaft. Because the push plate 302 is disposed within the upper hair channel 2021 and above the upper movable heating plate 20212, when an external force causes the clamping button 301 to move downward, the connecting plate of the clamping button 301 and the first end of the push plate 302 come into contact with each other, pushing the push plate 302 toward the curling head 20. When the push plate 302 moves toward the curling head 20, the bottom of the push plate 302 is provided with an inclined groove 3021 that contacts the protrusion 202122 on the upper movable heating plate 20212. This inclined structure pushes the upper movable heating plate 20212 toward the lower half of the hair channel 2022, thereby clamping the hair in the hair channel gap 2023. When straightening hair, the clamping assembly 30 allows the push plate 302 to be moved toward the curling head 20 by manually pressing the clamping button 301, thereby pressing down the upper movable heating plate 20212. The upper movable heating plate 20212 cooperates with the lower heating plate 20221 to clamp the hair in the hair channel gap 2023.

[0046] Referring to Figures 6 and 7 , there are four inclined grooves 3021, two of which are located on one side of the push plate 302, and the other two on the other side. Correspondingly, there are four protrusions 202122. As shown in Figures 6 and 7 , the four inclined grooves 3021 cooperate with the four protrusions 202122 to ensure that the push plate 302 applies a more uniform force to the upper movable heating plate 20212. This allows the upper movable heating plate 20212 to move downward in a direction parallel to the lower heating plate 20221. This allows the upper movable heating plate 20212 and the lower adding plate to clamp the hair more evenly, resulting in a better adding effect.

[0047] Referring to Figures 3 to 7 , a push plate return spring 303 is provided at the other end of the push plate 302. This spring is used to provide a return force to the push plate 302, driving it toward the curling main unit 10 and thereby removing the clamping force exerted by the push plate 302 on the upper movable heating plate 20212. As shown in Figures 3 and 5 , the push plate return spring 303 provides a return force to the end of the push plate 302 away from the clamping button 301. When the downward pressure from the clamping button 301 is removed, the push plate return spring 303 pushes the push plate 302 back to its original position, causing it to move away from the curling head 20. This releases the force between the push plate 302 and the upper movable heating plate 20212. The upper movable heating plate 20212 is in a normally closed state with the lower heating plate 20221 only under the action of the upper heating plate return spring 20213. At this time, the hair can be pulled into the hair-passing gap 2023 by pulling the hair in from the end opening and pushing the upper movable heating plate 20212 upward.

[0048] In one embodiment of the present invention, a button return spring 3011 is provided below the clamping button 301. This spring is used to reset the clamping button 301, causing the push plate 302 to move closer to the curling main unit 10, thereby removing the clamping force exerted by the push plate 302 on the upper movable heating plate 20212. The spring 3011 provides an upward force on the clamping button 301. When the downward force is removed, the spring 3011 pushes the clamping button 301 upward. This releases the force between the clamping button 301 and the push plate 302, allowing the push plate 302 to move away from the curling head 20. This releases the force between the push plate 302 and the upper movable heating plate 20212. The upper movable heating plate 20212 and the lower heating plate 20221 convert the hair clamping state into the hair holding state through the relatively small force of the upper heating plate return spring 20213.

[0049] Referring to Figures 2, 3 and 5, the curling head 20 further includes: an upper heat-insulating nozzle 203 and a lower heat-insulating nozzle 204, one end of the upper heat-insulating nozzle 203 is fixedly connected to the end of the upper half hair channel 2021, the other end of the push plate 302 is provided with a spring guide column 3023, the push plate return spring 303 is installed on the spring guide column 3023, the upper heat-insulating nozzle 203 and the spring guide column 3023 are correspondingly provided with a guide column groove, the push plate 30 When moving toward the upper heat-insulating nozzle 203, the spring guide post 3023 is inserted into the guide post groove, and the push plate return spring 303 contacts the upper heat-insulating nozzle 203. As shown in Figures 3 and 5, two spring guide posts 3023 may be provided, each of which may contain a push plate return spring 303. The ends of the push plate return spring 303 contact the upper heat-insulating nozzle 203 and the push plate 302. This provides a certain force for the push plate 302 to return to its original position. The upper heat-insulating nozzle 203 is provided with a guide post groove corresponding to the spring guide post 3023. When moving toward the upper heat-insulating nozzle 203, the spring guide post 3023 is inserted into the guide post groove, preventing the upper heat-insulating nozzle 203 from blocking the end of the push plate 302.

[0050] One end of the lower heat-insulating nozzle 204 is fixedly connected to the end of the lower half hair channel 2022, and a hair-inlet opening 2014 is formed between the upper heat-insulating nozzle 203 and the lower heat-insulating nozzle 204. As shown in FIG2 , the hair can be better guided into the heat channel 202 through the hair-inlet opening 2014.

[0051] Referring to Figures 1 and 5 , the curling head 20 further includes a curling head housing 205. Hair entry slots 2051 are provided on either side of the curling head housing 205, with hair retaining structures located in the middle of each of the two slots 2051. As shown in Figure 1 , the curling head housing 205 is positioned outside the curling head 20, preventing the user from being burned by the high temperature of the heat exchanger 202. Because the hair entry slots 2051 are provided on either side of the curling head housing 205, hair can be introduced into the heat exchanger 202 through the two slots 2051. When straightening hair, the hair needs to be placed into the hair exchange slots 2023. The hair can then pass through the hair retaining structures in the middle of the two slots 2051. This allows the hair to be positioned perpendicular to the heat exchanger 202, effectively performing the straightening operation. When curling hair, the hair on one side of the hair gap 2051 passes through the middle hair clamping structure, while the hair on the other side does not pass through the middle hair clamping structure. In this way, the hair and the heating tube 202 are at an oblique angle, thereby better performing the curling operation.

[0052] Referring to Figures 5 to 7 , the hair curling main unit 10 further includes a connector 102, through which the hair curling head 20 is fixedly connected to the hair curling main unit 10. The connector 102 is provided with a heat exchanger mounting position 1021, within which one end of the heat exchanger 202 is mounted. As shown in Figures 5 to 7 , one end of the connector 102 is mounted and fixed to the end of the hair curling main unit 10, while the other end of the connector 102 is fixedly connected to the heat exchanger 202. This provides a fixed connection between the hair curling main unit 10 and the hair curling head 20.

[0053] 5 to 7 , the hair curling main unit 10 further includes a motor 103 and a gear 104. The connecting head 102 is provided with a motor housing 1022, within which the motor 103 is mounted. The gear 104 is fixedly connected to the rotating shaft of the motor 103. The end of the hair curling lever 201 is provided with a lever connector 2011, which is provided on the connecting head 102. Drive gears 20111 are provided on the inner side of the lever connector 2011. The gear 104 engages with the gear 104 to rotate the hair curling lever 201 under the influence of the motor 103. As shown in FIG5 , after the motor 103 is installed in the motor housing 1022, the gear 104 can be extended from the bottom of the motor housing 1022. The lever connector 2011 is sleeved onto the outer surface of the connecting head 102. In this way, the gear 104 can mesh with the transmission gear 20111 inside the lever connector 2011. Under the action of the motor 103, the lever connector 2011 and the lever are driven to rotate, thereby rolling the hair into the outer surface of the heat exchanger 202.
