Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing tools, in particular to an electromagnetic induction hairdressing styling structure and a hairdressing device. Background Art

[0002] Existing hair styling devices generally have the problem of long heating times during use, which significantly affects the user's hairdressing efficiency. Most hair styling devices take several minutes to reach the ideal operating temperature after being turned on. This is mainly due to the technical limitations of traditional heating elements (such as PTC ceramic heaters and metal heating films). These elements heat up slowly and are affected by material quality and thermal fatigue effects. After long-term use, they can easily lead to uneven temperature distribution, local overheating or uneven temperatures, which not only affects the hairdressing effect, but may also damage the hair quality. For hairdressing practitioners who use the equipment frequently, the long preheating time of the equipment not only wastes precious time, but also increases work fatigue, directly affecting work efficiency.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature designated "first" or "second" may explicitly or implicitly include at least one such feature.

[0025] The embodiment of the utility model provides an electromagnetic induction hair styling structure, combined with Figures 1 to 5 As shown, it includes a circuit board 1, an electromagnetic induction component 2 and a heating sheet 3 suitable for contacting hair. The electromagnetic induction component 2 includes a coil fixing bracket 21 and an induction heating coil 22 wound around the coil fixing bracket 21. The coil fixing bracket 21 is connected to the heating sheet 3. The induction heating coil 22 is spaced apart from the heating sheet 3. The induction heating coil 22 is electrically connected to the circuit board 1. The heating sheet 3 is made of ferromagnetic material. When working, the induction heating coil 22 uses electromagnetic induction to interact with the heating sheet 3, so that the heating sheet 3 is quickly heated to style the hair.

[0026] Among them, the coil fixing bracket 21 is used to support the induction heating coil 22 so that it can be stably installed inside the overall structure; the induction heating coil 22 is installed on the fixing bracket and electrically connected to the circuit board 1. When powered on, the induction heating coil 22 starts to work, generating a high-frequency alternating electromagnetic field through electromagnetic induction, and an eddy current effect is generated inside the heating plate 3 made of ferromagnetic material, thereby directly generating heat inside the heating plate 3; the heating plate 3 is made of ferromagnetic material and is in direct contact with the hair. Since the ferromagnetic material has good heating performance in the magnetic field, it can generate heat through magnetic induction and has good thermal conductivity. It can quickly and evenly distribute heat on the surface of the heating plate 3, avoiding the temperature unevenness or local overheating problems that occur in traditional hair styling devices, and ensuring the uniformity and stability of the styling effect.

[0027] In the electromagnetic induction hair styling structure of this embodiment, the induction heating coil 22 is installed on the coil fixing bracket 21 by winding, making the structure compact and firm. The coil fixing bracket 21 serves as a supporting structure and is also connected to the heating plate 3. The overall structure is simple. The induction heating coil 22 and the heating plate 2 are arranged in a non-contact manner, ensuring that the induction heating coil 22 and the heating plate 3 use the principle of electromagnetic induction to enable the heating plate 3 to quickly reach the required temperature. Heating can be achieved almost at the moment of power-on, greatly shortening the preheating time, meeting the needs of hairdressing practitioners who use the hair frequently, and improving work efficiency. The heating plate 3 can be evenly heated under the action of the induced magnetic field, ensuring that each strand of hair can be evenly heated, and the styling effect is more ideal. This electromagnetic induction heating directly heats the inside of the heating plate 3, reducing the delay caused by the heat conduction process and significantly shortening the heating time. The working temperature can usually be reached in 30 seconds or even less. The non-contact heating method also reduces unnecessary energy waste, meeting the needs of energy conservation and environmental protection.

[0028] Optionally, combined Figure 2 、 Figure 3 、 Figure 4 As shown, an annular groove 211 is provided on the circumference of the coil fixing bracket 21, and the induction heating coil 22 is wound in the annular groove 211. The annular groove 211 is used to guide and fix the induction heating coil 22 so that it can be wound along the circumference of the bracket, ensuring the neat arrangement of the induction heating coil 22, avoiding winding misalignment or coils being too close together, thereby preventing electromagnetic interference and overheating problems, and also increasing the compactness of the coil and improving the electromagnetic induction efficiency.

[0029] Optionally, combined Figure 2 、 Figure 3As shown, the induction heating coil 22 is flatly wound from the inside out within the annular groove 211. The induction heating coil 22 extends outward layer by layer in a stacked manner, ensuring uniform distribution of the coil within the annular groove 211. The uniform arrangement of the flatly wound coils helps to reduce local electromagnetic interference and enhance the stability of the electromagnetic induction effect. The annular groove 211 allows for a compact and orderly coil layout, saving internal space in the hairdresser and ensuring the compactness of the overall structure. The induction heating coil 22 has a square structure, with its four sides matching the edges of the coil fixing bracket 21, allowing it to fit tightly within the square annular groove 211. This allows the hairdresser to accommodate the efficient induction heating coil 22 within a more compact structure, resulting in more efficient space utilization and a more concentrated electromagnetic field distribution.

[0030] Optionally, combined Figure 5 As shown, the coil fixing bracket 21 is provided with a notch 212 that is electrically connected to the annular groove 211. Both ends of the induction heating coil 22 pass through the notch 212 and are electrically connected to the circuit board 1. A notch 212 is provided on the side of the annular groove 211 of the coil fixing bracket 21 near the circuit board 1, allowing the leading and trailing ends of the induction heating coil 22 to pass through the notch 212. During installation, the leading and trailing ends of the induction heating coil 22 are guided through the notch 212 to achieve electrical connection with the circuit board 1 without affecting the stable positioning of the coil in the groove. This simplifies the assembly process and improves production efficiency.

[0031] Optionally, combined Figure 2 、 Figure 3 As shown, a silicone pad 23 is provided between the heating plate 3 and the coil fixing bracket 21; the silicone pad 23 plays the role of thermal insulation and protection. The silicone pad 23 has a moderate thickness and can provide effective thermal isolation without affecting the electromagnetic induction heating effect, and can effectively prevent the high temperature generated by the heating plate 3 from being conducted to the coil fixing bracket 21.

[0032] Optionally, combined Figure 1 、 Figure 4 As shown, it also includes a high-voltage socket 4 electrically connected to the circuit board 1. The high-voltage socket 4 is suitable for being electrically connected to an external power source. When the high-voltage socket 4 is energized, the induction heating coil 22 operates to interact with the heating plate 3 by electromagnetic induction, so that the heating plate 3 is rapidly heated. The high-voltage socket 4 provides the ability to directly connect to an external power source, so that the hairdressing device can be directly powered by high voltage in indoor and fixed power supply scenarios. Here, high-voltage power supply refers to 220V mains power supply. The high-voltage socket 4 is preferably an AC power socket, which is easy to plug and unplug. The user can quickly connect or disconnect the power cord, and can provide a stable power supply to ensure that the electromagnetic induction component 2 quickly and efficiently heats the heating plate 3, shortening the heating time and improving the user experience.

[0033] Optionally, combined Figure 2 、 Figure 3 、 Figure 5 As shown, the edge of the heating sheet 3 is folded upward to form a receiving cavity 31 for the electromagnetic induction component 2. The receiving cavity 31 can wrap around the circumference of the electromagnetic induction component 2 to prevent the electromagnetic induction component 2 from being disturbed by the outside world during operation and maintain structural stability. As a part of the heating sheet 3, the receiving cavity 31 is integrated with the main structure of the heating sheet 3, avoiding additional connectors and reducing structural complexity, making the overall structure of the device more stable, durable, and more compact.

[0034] Optionally, combined Figure 2 、 Figure 3 、 Figure 5 As shown, the top edge of the accommodating cavity 31 extends upward to form a plurality of fixing plates 32, and the plurality of fixing plates 32 are arranged at intervals; the top surface of the coil fixing bracket 21 is provided with a plurality of mounting grooves 213 corresponding one to one with the fixing plates 32. During assembly, the fixing plates 32 are bent and matched with the mounting grooves 213 to fix the electromagnetic induction component 2 and the heating plate 3 to each other.

[0035] Among them, during assembly, by slightly bending the fixing plate 32 and embedding it into the installation groove 213, a close combination of the accommodating cavity 31 and the electromagnetic induction component 2 is achieved, reducing the possibility of loosening of components. The method of bending the fixing plate 32 and inserting it into the installation groove 213 does not require the use of additional fasteners, simplifies the fixing process of the component, facilitates production and assembly, and improves production efficiency; the fixing plate 32 adopts an upward extending design, so that it is not easy to deform or break when bent, and the material of the fixing plate 32 has appropriate elasticity, so that it can be firmly stuck in the installation groove 213 after bending; the setting of multiple fixing plates 32 and multiple installation grooves 213 forms a multi-point support structure to ensure the stability of the overall connection and uniform force.

[0036] Another embodiment of the present invention provides a hair styling device, comprising the electromagnetic induction hair styling structure as described above.

[0037] In the hairdressing device of this embodiment, the induction heating coil 22 is mounted on the coil fixing bracket 21 by winding, making the structure compact and firm. The coil fixing bracket 21 serves as a supporting structure and is also connected to the heating plate 3. The overall structure is simple. In addition, the induction heating coil 22 and the heating plate 2 are arranged in a non-contact manner, ensuring that the induction heating coil 22 and the heating plate 3 use the principle of electromagnetic induction to enable the heating plate 3 to quickly reach the required temperature. Heating can be achieved almost at the moment of power-on, greatly shortening the preheating time, meeting the needs of frequent hairdressing practitioners, and improving work efficiency; the ferromagnetic material heating plate 3 can be evenly heated under the action of the induced magnetic field, ensuring that each strand of hair can be evenly heated, and the styling effect is more ideal; this electromagnetic induction heating directly heats the interior of the heating plate 3, reducing the delay caused by the heat conduction process and significantly shortening the heating time. The working temperature can usually be reached in 30 seconds or even less. The non-contact heating method also reduces unnecessary energy waste, meeting the needs of energy conservation and environmental protection.

[0038] Optionally, combined Figure 1 As shown, it includes a first clamping plate 5 and a second clamping plate 6 that are hingedly connected to each other. The first clamping plate 5 and the second clamping plate 6 are respectively installed with a set of electromagnetic induction components 2 and a heating plate 3. The two heating plates 3 are arranged opposite to each other. When working, the two heating plates 3 can heat together to shape the hair. The hair styling device adopts a hinged connection design, which allows the first clamping plate 5 and the second clamping plate 6 to be flexibly opened and closed, which is convenient for user operation and allows the user to adjust the opening and closing angle of the clamping plate as needed to facilitate clamping hair of different lengths and thicknesses; the heating plate 3 is arranged on the inner side of each clamping plate, and the two heating plates 3 are arranged opposite to each other to form a clamping area, which can achieve double-sided heating when working, ensuring that the hair is evenly heated during the clamping process to achieve the best styling effect.
