[0034] like Figures 1 to 7 As shown, this application provides a multi-functional curling iron, which includes a main body 100, a curling component 200, a driving assembly 300, a heating element 400, and a light-emitting element 500. The main body 100 is provided with a receiving space. The curling component 200 is rotatably connected to the main body 100. The driving assembly 300 is located in the receiving space and is drivenly connected to the curling component 200 to drive the curling component 200 to rotate. The heating element 400 is fixed to the main body 100 or to the curling component 200. The light-emitting element 500 is fixed to the main body 100 or to the curling component 200.

[0035] In one specific embodiment, the main body 100 is the basic structural part of the entire multi-functional curling iron. Its internal space is used to install other components such as the drive assembly 300, providing space for the normal operation of the curling iron. The curling element 200 is the component that directly acts on the hair to curl it. Through a rotatable connection with the main body 100, it can rotate under the drive of the drive assembly 300, thereby completing the curling action. The drive assembly 300, as a power source, is located within the space and is driven by the curling element 200, providing power for its rotation. In this embodiment, the heating element 400 and the light-emitting element 500 are both fixedly mounted on the main body 100. In another embodiment, both the heating element 400 and the light-emitting element 500 can be fixedly mounted on the curling element 200. The heating element 400 is used to heat the hair, enabling it to quickly set during the curling process. The light-emitting element 500 can emit light of a preset wavelength. In this embodiment, the light emitted by the light-emitting element 500 is red light with a wavelength of 600 to 700 nanometers. Red light has strong penetrability and can penetrate deep into skin tissue, promoting cell metabolism, increasing collagen production, and improving blood circulation. It can be used to treat hair loss, scalp inflammation, and promote hair growth. In another specific embodiment, the light-emitting element 500 can also emit light of other wavelengths, such as blue light, ultraviolet light, or mixed light.

[0036] In summary, this multi-functional curling iron integrates curling and phototherapy functions into one unit. Compared with traditional single-function curling irons, it greatly expands the product's functionality. Users do not need to purchase additional phototherapy equipment to perform scalp care during the curling process, improving convenience and efficiency. It meets users' dual needs for hair styling and scalp care and has good market application prospects.

[0037] like Figure 3 As shown, the main body 100 includes a holding part 110 and a mounting part 120 disposed at one end of the holding part 110. The hair curling part 200 is rotatably connected to the holding part 110 and is disposed around the mounting part 120. The heating element 400 and / or the light-emitting element 500 are disposed on the mounting part 120.

[0038] In one specific embodiment, the main body 100 is divided into a gripping part 110 and a mounting part 120. The gripping part 110 is the part where the user holds the curling iron. The gripping part 110 is ergonomically designed for easy holding for extended periods. The mounting part 120 is located at one end of the gripping part 110 and is fixedly assembled with the gripping part 110. The mounting part 120 serves to mount and fix components such as the heating element 400 and the light-emitting element 500. The curling iron 200 is rotatably connected to the gripping part 110 and surrounds the mounting part 120.

[0039] In one embodiment, both the heating element 400 and the light-emitting element 500 are fixed to the mounting portion 120. Alternatively, in another embodiment, one of the heating element 400 and the light-emitting element 500 is fixed to the mounting portion 120, and the other is fixed to the curling hair component 200.

[0040] When the heating element 400 and the light-emitting element 500 are installed in the curling iron 200, both the heating element 400 and the light-emitting element 500 are fixedly installed on the inner side of the curling iron 200 near the main body 100. For example, the heating element 400 can be disposed inside the curling iron 200, which is a metal structure capable of transferring heat from the heating element 400. The light-emitting element 500 can be disposed inside the curling iron 200, with a window provided in the curling iron 200 for the light-emitting element 500 to allow light to pass through.

[0041] In summary, by placing the heating element 400 and the light-emitting element 500 in the mounting section 120, the structure of the curling iron becomes more compact and rational. The curling element 200 surrounds the mounting section 120, allowing the heat generated by the heating element 400 to be directly transferred to the hair, improving curling efficiency. The light-emitting element 500, positioned in the mounting section 120, allows light to directly illuminate the hair and scalp, avoiding blind spots and effectively enhancing the effectiveness of phototherapy.

[0042] Furthermore, such as Figure 2 As shown, in another specific embodiment, the multifunctional curling iron also includes a stimulation element 600, which is mounted on the curling member 200. The stimulation element 600 includes either or both of a heating element and a light-emitting element, and the stimulation element 600 emits light and heat inwards. Specifically, while the heating element 400 and the light-emitting element 500 are provided on the mounting part 120, the stimulation element 600 can also be provided on the curling member 200. Therefore, when the hair is located between the mounting part 120 and the curling member 200, both sides of the hair are surrounded by light and heat, resulting in excellent phototherapy and heating effects. It should be noted that the structure of the heating element and the light-emitting element of the stimulation element 600 can be the same as the structure of the heating element 400 and the light-emitting element 500 on the mounting part 120.

[0043] Please refer to the reference. Figure 5 Optionally, the hair curler 200 includes a plurality of curling teeth 230 distributed along its rotation direction, and each curling tooth 230 may be provided with a stimulation element 600, so that the plurality of stimulation elements 600 are arranged along the circumference of the hair curler 200.

[0044] like Figure 7 As shown, the heating element 400 and the light-emitting element 500 are configured in multiples and are alternately distributed along the rotation direction of the curling element 200.

[0045] In one specific embodiment, two heating elements 400 and two light-emitting elements 500 are provided. The mounting portion 120 is generally cuboid in shape. The two heating elements 400 and two light-emitting elements 500 are respectively disposed on four different sides of the mounting portion 120, and the heating elements 400 and light-emitting elements 500 are alternately distributed along the rotation direction of the curling member 200, as shown in the following figure. Figure 1 As shown in B in the figure. In another specific embodiment, the number of heating elements 400 and light-emitting elements 500 can be adapted. During the curling process, the hair rotates with the curling element 200 and passes through the heating element 400 and light-emitting element 500 in sequence, so that it can receive heat for styling while continuously receiving light therapy, thus achieving simultaneous curling and light therapy.

[0046] In summary, the alternating distribution of heating elements 400 and light-emitting elements 500 effectively improves the performance of the curling iron. From a heating perspective, the evenly distributed heating elements 400 ensure more uniform heating of the hair, improving the quality of the curls. From a phototherapy perspective, the alternating light-emitting elements 500 provide more abundant and even light exposure, enhancing the phototherapy effect.

[0047] like Figure 3 and Figure 7 As shown, the mounting portion 120 extends along the rotation axis of the curling member 200, and the heating element 400 and the light-emitting element 500 both extend in a strip-like arrangement along the length direction of the mounting portion 120.

[0048] In one specific embodiment, the position of the rotation axis of the hair curler 200 is as follows: Figure 1 As shown in Figure C, the mounting portion 120 is located at the rotation axis of the hair curler 200 and extends along the rotation axis of the hair curler 200 to provide a suitable carrier for the installation of the heating element 400 and the light-emitting element 500. Both the heating element 400 and the light-emitting element 500 are elongated strips and are installed along the length of the mounting portion 120. This arrangement is compatible with the rotation direction of the hair curler 200, enabling continuous and stable heating and phototherapy of the head during the rotation of the hair curler 200. The strip-shaped arrangement of the heating element 400 increases the contact area with the hair, allowing for more thorough heat transfer; the strip-shaped arrangement of the light-emitting element 500 also provides a wider area for phototherapy irradiation.

[0049] In summary, arranging the heating element 400 and the light-emitting element 500 in a strip shape along the length of the mounting portion 120 offers numerous advantages. Regarding heating, the increased contact area accelerates heat transfer, shortens curling time, and improves efficiency. In terms of phototherapy, a wider range of light irradiation allows the scalp to receive more comprehensive light therapy, enhancing the therapeutic effect and promoting hair and scalp health.

[0050] like Figure 3 and Figure 4 As shown, the mounting part 120 includes a first part 121 and a second part 122. The first part 121 is exposed outside the gripping part 110 and is used for mounting the heating element 400 and the light-emitting element 500. The second part 122 is located inside the gripping part 110. The second part 122 and the gripping part 110 together clamp the driving assembly 300.

[0051] In one specific embodiment, the mounting portion 120 is divided into a first part 121 and a second part 122 along its length. The first part 121 and the second part 122 are integrally formed. The first part 121 is exposed outside the gripping portion 110 and its main function is to provide a mounting position for the heating element 400 and the light-emitting element 500. The second part 122 is located in the receiving space inside the gripping portion 110. A clearance groove 123 is provided on each side of the second part 122. Two fixing posts 111 are provided in the gripping portion 110. The two fixing posts 111 pass through the clearance grooves 123 on both sides of the second part 122 to fix the position of the mounting portion 120. Fixing holes are also provided on the second part 122. Screws are used to fix the second part 122 and the gripping portion 110 separately and securely.

[0052] The drive assembly 300 includes a drive motor 310, which is the power source of the entire drive assembly 300. It converts electrical energy into mechanical energy and outputs rotational power. The drive motor 310 is located in the receiving space of the gripping part 110. The drive motor 310 includes a first positioning plate 311. The second part 122 includes two parallel and spaced first clamping plates 125. The receiving space of the gripping part 110 is also provided with two parallel and spaced second clamping plates 112. The first clamping plates 125 and the second clamping plates 112 clamp and fix the first positioning plate 311 from opposite sides to fix the position of the drive motor 310.

[0053] In summary, by dividing the mounting section 120 into two parts, each undertaking a different function, the structural layout of the multi-functional curling iron is optimized. The first part 121 is used to mount the heating element 400 and the light-emitting element 500, providing the necessary heat for curling the hair and providing light therapy light to the head; the second part 122 cooperates with the gripping part 110 to clamp the drive motor 310, ensuring the stability of the power source and enabling the curling iron 200 to rotate smoothly.

[0054] like Figure 7 As shown, the first part 121 is provided with a receiving chamber 126, and the light-emitting element 500 is located in the receiving chamber 126.

[0055] In one specific embodiment, a cuboid-shaped receiving chamber 126 is provided inside the first part 121. The receiving chamber 126 is arranged along the length of the first part 121, and the light-emitting element 500 is disposed in the receiving chamber 126. The arrangement of the receiving chamber 126 provides a dedicated installation space for the light-emitting element 500, which can protect the light-emitting element 500 from being damaged by collision or squeezing during the use of the curling iron. The outer surface of the first part 121 is provided with a mounting groove 127 corresponding to the position of the light-emitting element 500. The shape of the mounting groove 127 matches the shape of the light-emitting element 500. The mounting groove 127 is provided with light-transmitting holes 128 arranged at intervals along the length direction of the mounting groove 127. The light-transmitting holes 128 communicate with the outside world. The light-emitting element 500 includes an LED bead 510. The position of the light-transmitting hole 128 matches the position of the LED bead 510, so that the light emitted by the LED bead 510 on the light-emitting element 500 can be emitted from the light-transmitting hole 128. The 510 LED can be made of light-emitting diodes (LEDs), lasers, organic light-emitting diodes (OLEDs), quantum dot light-emitting diodes (QLEDs), micro LEDs, or other applicable technologies.

[0056] The multi-functional curling iron also includes a transparent cover plate 520. The shape of the cover plate 520 matches the shape of the mounting slot 127, and the cover plate 520 is fixedly installed in the mounting slot 127. The transparency of the cover plate 520 allows the light emitted by the light-emitting element 500 to pass through smoothly without affecting the light therapy effect. The cover plate 520 provides physical protection for the light-emitting element 500, preventing damage from impacts, scratches, etc., during use. Furthermore, the cover plate 520 prevents dust, hair clippings, and other foreign objects from entering the light-transmitting hole 128, keeping the light-emitting element 500 clean and ensuring stable light therapy effects.

[0057] like Figure 4 , 5 As shown in Figure 6, the mounting part 120 has a first protrusion 130, the gripping part 110 includes a gripping housing 113, one end of the hair curler 200 is inserted into the gripping housing 113, the gripping housing 113 has a second protrusion 118, the end of the hair curler 200 has a stepped part 240, the stepped part 240 is sandwiched between the first protrusion 130 and the second protrusion 118, and the first protrusion 130 and the second protrusion 118 are distributed at intervals along the rotation axis of the hair curler 200.

[0058] In one specific embodiment, the hollow portion inside the grip shell 113 serves as an accommodating space. The grip shell 113 has an opening 117 on one side. The hair curler 200 is inserted into the grip shell 113 through the opening 117. A first protrusion 130 is provided at the connection between the first part 121 and the second part 122 of the mounting part 120. The first protrusion 130 is annular. The hair curler 200 has a stepped portion 240 near the opening 117. A ring-shaped second protrusion 118 is provided around the perimeter of the opening 117 of the grip shell 113. The first protrusion 130 and the second protrusion 118 clamp the upper and lower sides of the stepped portion 240 to fix the hair curler 200.

[0059] In summary, one end of the curling iron 200 is inserted into the holding housing 113 and is clamped between the first protrusion 130 and the second protrusion 118 through the stepped portion 240. This connection method can restrict the movement of the curling iron 200 in the axial direction without affecting its rotation around the rotation axis.

[0060] like Figure 6 As shown, the drive assembly 300 includes a battery 320. The gripping housing 113 has a plurality of first slots 114 evenly distributed along the length of the battery 320 inside. The battery 320 is embedded in the first slots 114 to fix the position of the battery 320.

[0061] In one specific embodiment, the drive assembly 300 includes a battery 320, which is the energy source of the drive assembly 300 and provides power to components such as the drive motor 310. The battery 320 is cylindrical and is located in the receiving space of the grip shell 113. The grip shell 113 has a plurality of first slots 114 evenly distributed along the length of the battery 320, and the plurality of first slots 114 are evenly distributed around the circumference of the battery 320. The battery 320 is fixed by being embedded in the first slots 114.

[0062] In summary, the first slot 114 provides the battery 320 with an accurate installation position and a reliable fixing method, which can prevent the battery 320 from shifting or shaking during the use of the curling iron, and ensure the stability of the power supply of the battery 320.

[0063] like Figure 5 As shown, the drive assembly 300 also includes a drive gear 330, which is fixedly installed at the output end of the drive motor 310. The hair curler 200 is provided with a gear engagement part 210, which engages eccentrically with the drive gear 330.

[0064] In one specific embodiment, the drive assembly 300 further includes a drive gear 330, which is fixedly mounted on the output end of the drive motor 310. The end of the curling iron 200 inserted into the holding housing 113 is open and has a ring of serrations 211 on its inner side to form a gear engagement portion 210. The gear engagement portion 210 surrounds the outer periphery of the drive gear 330, and the gear engagement portion 210 and the drive gear 330 are eccentrically meshed. Eccentric meshing means that the centers of the drive gear 330 and the gear engagement portion 210 do not coincide. Compared with the traditional concentric meshing method, eccentric meshing has lower precision requirements for product parts and a simpler assembly process, which can effectively reduce production costs.

[0065] In summary, the design of using a drive motor 310 and a drive gear 330 in conjunction, with eccentric meshing to rotate the curling iron 200, provides stable and reliable curling power. Compared to traditional manual curling methods, this electric drive method is more labor-saving and efficient. Furthermore, the eccentric meshing design effectively reduces production costs compared to a typical concentric meshing design.

[0066] In one specific embodiment, the drive motor 310 further includes a second positioning plate 312, which is another positioning component on the drive motor 310. The second positioning plate 312 is arranged parallel to and spaced apart from the first positioning plate 311. A first baffle 129 is provided on the second part 122 of the mounting part 120. The first baffle 129 is rectangular and located on the second part 122 at a position corresponding to the second positioning plate 312. A second baffle 115 is provided inside the grip shell 113. The second baffle 115 is rectangular and located on the grip shell 113 at a position corresponding to the second positioning plate 312. The first baffle 129 and the second baffle 115 are respectively located on opposite sides of the second positioning plate 312. There are two first baffles 129 and two second baffles 115, which are arranged parallel to and spaced apart. The first baffle 129 and the second baffle 115 abut against the second positioning plate 312 from opposite sides of the second positioning plate 312, so as to further fix the position of the drive motor 310.

[0067] In summary, the addition of the second positioning plate 312 further enhances the stability and reliability of the drive motor 310 installation. Through multi-directional positioning and fixing, it effectively prevents displacement and loosening of the drive motor 310 during use, ensuring the normal operation of the drive assembly 300.

[0068] In one specific embodiment, a second slot 116 is provided inside the gripping housing 113 at the position corresponding to the drive motor 310. The shape of the second slot 116 matches the shape of the drive motor 310, so that the drive motor 310 can be tightly embedded in the second slot 116. This embedded installation method not only ensures that the drive motor 310 is firmly installed, but also plays a certain positioning role.

[0069] In one specific embodiment, the drive assembly 300 further includes a circuit board 340, which is fixedly mounted in the receiving space by screws.
