Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0024] The embodiment of the utility model provides a dual-power heating structure for hairdressing, combined with Figure 1 、 Figure 2 、 Figure 3 As shown, it includes a circuit board 1, a high-voltage power component 2, a low-voltage power component 3 and a heating plate 4 suitable for contact with hair. The high-voltage power component 2 and the low-voltage power component 3 are both communicatively connected to the circuit board 1. The high-voltage power component 2 includes a high-voltage input component electrically connected to the circuit board 1, and the low-voltage power component 3 includes a low-voltage input component electrically connected to the circuit board 1; when the high-voltage input component is energized, the high-voltage power component 2 works to quickly heat the heating plate 4; when the low-voltage input component is energized, the low-voltage power component 3 works to heat the heating plate 4.

[0025] Among them, there are multiple circuit connection points arranged on the circuit board 1, which are used to connect the high-voltage power component 2 and the low-voltage power component 3; when the user selects the high-voltage mode, the circuit board 1 supplies power to the high-voltage input component and activates the high-voltage power component 2. The high-voltage power component 2 uses the principle of rapid current conduction or electromagnetic induction to make the heating plate 4 reach a higher operating temperature within a few seconds; when the user selects the low-voltage mode, the circuit board 1 supplies power to the low-voltage input component and activates the low-voltage power component 3. The low-voltage power component 3 heats the heating plate 4 with lower power; the communication connection method is wired electrical connection or wireless connection, and the high-voltage power component 2 and the low-voltage power component 3 are controlled and adjusted through the circuit board 1. The circuit board 1 can automatically switch between high-voltage and low-voltage modes according to the user's selection, thereby improving convenience and intelligence.

[0026] The dual-power heating structure for hairdressing in this embodiment is designed with two independent power systems, a high-voltage power component 2 and a low-voltage power component 3. After the high-voltage power component 2 is energized through the high-voltage input component, it can rapidly heat up the heating plate 4 in a short time, which is suitable for situations where rapid styling is required; after the low-voltage power component 3 is energized through the low-voltage input component, it works at a lower power for gentle heating, which is suitable for scenarios where battery 31 is powered or energy consumption requirements are low; the power selection is highly flexible, which improves the overall user experience.

[0027] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 As shown, the high-voltage input component is a high-voltage socket 21 suitable for electrically connecting to an external power supply. The high-voltage socket 21 provides the ability to directly connect to an external power supply, so that the hairdressing tool can be directly powered by high voltage in indoor and fixed power supply scenarios, reducing dependence on the battery 31; the high-voltage socket 21 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, ensuring that the high-voltage power component 2 quickly and efficiently heats the heating plate 4, shortening the heating time and improving the user experience.

[0028] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 As shown, the low-voltage input component is a battery 31, that is, the low-voltage input component can be directly connected to the battery 31 to provide a portable, wireless power supply suitable for use when traveling or when there is no external power source. The battery 31 power supply design allows the user to continue using the hair straightener even when not plugged in, maintaining flexibility and convenience. The low-voltage input component is a low-voltage socket 32 ​​suitable for electrical connection to an external power source. That is, the low-voltage input component can also be connected to an external low-voltage power source through the low-voltage socket 32. The user can choose to power the low-voltage power component 3 through an adapted low-voltage power source (such as a USB charger or other low-voltage charging device). The low-voltage socket 32 ​​is preferably a Type-C interface, which is highly versatile and compatible with various types of charging cables. The battery 31 and low-voltage socket 32 ​​can be used independently or switched between them as needed. For example, when the battery 31 is low on power, the user can directly connect to an external power source (such as via a USB cable) and continue using the hair straightener without waiting for charging.

[0029] Optionally, combined Figure 1 、 Figure 2 、 Figure 3As shown, the high-voltage power component 2 includes a coil fixing bracket 22 and a high-frequency induction heating coil 23 installed on the coil fixing bracket 22. The heating plate 4 is made of ferromagnetic material, and the high-frequency induction heating coil 23 is electrically connected to the circuit board 1. When the high-voltage input component is energized, the high-frequency induction heating coil 23 uses electromagnetic induction to interact with the heating plate 4 to quickly heat the heating plate 4.

[0030] Among them, the coil fixing bracket 22 is used to support and fix the position of the high-frequency induction heating coil 23 to ensure that it is stably installed in the heating structure; when the high-voltage input component is energized, the high-frequency induction heating coil 23 starts to work, and generates a high-frequency alternating electromagnetic field through electromagnetic induction, and an eddy current effect is generated inside the heating plate 4 made of ferromagnetic material, thereby directly generating heat inside the heating plate 4. In this embodiment, due to the use of electromagnetic induction heating, the ferromagnetic heating plate 4 can heat up rapidly in a short period of time. Compared with the heat conduction method of traditional PTC ceramic heaters or metal heating films 33, electromagnetic induction heating directly heats the inside of the heating plate 4, reducing the delay generated in the heat conduction process and significantly shortening the heating time. It can usually reach the operating temperature in 30 seconds or even less. The non-contact heating method also reduces unnecessary energy waste. Especially in the high-voltage power mode, it can achieve faster heating effects with lower energy consumption, which meets the needs of energy conservation and environmental protection.

[0031] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 As shown, an annular groove 221 is provided on the circumference of the coil fixing bracket 22, and the high-frequency induction heating coil 23 is wound in the annular groove 221; the annular groove 221 is used to guide and fix the high-frequency induction heating coil 23 so that it can be wound along the circumference of the bracket, ensuring the neat arrangement of the high-frequency induction heating coil 23, avoiding winding misalignment or the coils being too close to each other, thereby preventing electromagnetic interference and overheating problems, and also increasing the compactness of the coil and improving the electromagnetic induction efficiency.

[0032] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 As shown, the heating plate 4 and the coil fixing bracket 22 are spaced apart, and the low-voltage power component 3 is arranged between the heating plate 4 and the coil fixing bracket 22; a certain physical distance is maintained between the heating plate 4 and the coil fixing bracket 22 to ensure that no direct heat conduction occurs between the two, so that the high-voltage and low-voltage heating systems can operate more efficiently and independently, ensuring that the heating plate 4 can be efficiently heated in different power modes.

[0033] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 As shown, the low-voltage power component 3 includes a heating film 33 electrically connected to the circuit board 1, and the heating film 33 is thermally conductively connected to the heating plate 4. When the low-voltage input component is energized, the heating film 33 generates heat to heat the heating plate 4.

[0034] Among them, the heating film 33 is connected to the circuit board 1 through a wire. When the low-voltage input component (such as a battery 31 or a low-voltage power supply) is energized, the heating film 33 will work and generate heat; the heating film 33 is in close contact with the heating plate 4, which can ensure that the heat generated by the heating film 33 is directly transferred to the heating plate 4 through heat conduction, and the temperature rises quickly, ensuring that the heating plate 4 can also work efficiently in the low-voltage heating mode; the material of the heating film 33 is preferably polyimide, which can achieve uniform heating in a very short time, providing a smoother hairdressing effect, and at the same time, the heating speed is fast, which improves the user experience; this embodiment uses Joule's law to achieve heating, that is, when current passes through the conductive layer, heat is generated, and the magnitude of the heat is proportional to the magnitude of the current and the resistance of the conductive layer. By controlling the magnitude of the current and the resistance of the conductive layer, the heating of the heating film 33 can be controlled.

[0035] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 As shown, it also includes a silicone pad 5, which is installed on the side of the heating film 33 away from the heating plate 4. The silicone pad 5 plays a role of thermal insulation and protection, preventing the heat of the heating film 33 from being conducted to the area that does not need heating, reducing the heat loss of the equipment during use, and thus ensuring the stability of the heating process.

[0036] Another embodiment of the present invention provides a hair straightener, comprising the dual-power heating structure for hairdressing as described above.

[0037] The hair straightener in this embodiment is designed with two independent power systems, a high-voltage power component 2 and a low-voltage power component 3. After the high-voltage power component 2 is energized through the high-voltage input component, it can rapidly heat up the heating plate 4 in a short time, which is suitable for situations where quick shaping is required; after the low-voltage power component 3 is energized through the low-voltage input component, it operates at a lower power for gentle heating, which is suitable for scenarios where power is supplied by the battery 31 or where low energy consumption requirements are required; the power selection is highly flexible, which improves the overall user experience.

[0038] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 As shown, the hair styling apparatus comprises a first clamping plate 6 and a second clamping plate 7 hingedly connected to each other. The first clamping plate 6 and the second clamping plate 7 are respectively installed with a set of high-voltage power components 2, a set of low-voltage power components 3 and a heating plate 4. The two heating plates 4 are arranged opposite to each other. When working, the two heating plates 4 can heat together to style the hair.

[0039] Among them, the hair straightener adopts a hinged connection design, so that the first clamping plate 6 and the second clamping plate 7 can be flexibly opened and closed, which is convenient for user operation and allows the user to adjust the opening and closing angles of the clamping plates as needed to clamp hair of different lengths and thicknesses; the heating plate 4 is arranged on the inner side of each clamping plate, and the two heating plates 4 are arranged opposite to each other to form a clamping area, which can achieve double-sided heating during operation, ensuring that the hair is evenly heated during the clamping process to achieve the best styling effect.
