[0030] See also Figures 1 to 4 As shown, the utility model discloses a specific embodiment of a heating component, including: a heat conductor 10, the outer surface of the heat conductor 10 is provided with a heating layer 20, the heat conductor 10 is located on the outside of the heating layer 20 and is also wrapped with an insulating cloth 30, and the heating layer 20 is butterfly-shaped or spiral-shaped.

[0031] Specifically, the heating layer 20 is printed directly onto the outer surface of the thermal conductor 10 using thick-film printing. This thick-film printing technique allows the heating layer 20 to be printed directly onto the surface of the thermal conductor 10, forming a component that converts electrical energy into thermal energy. When current passes through the heating layer 20, due to the resistance, the electrical energy is converted into thermal energy and transferred outward through the thermal conductor 10, achieving the heating effect.

[0032] Specifically, by printing the heating layer 20 directly onto the outer surface of the heat conductor 10 and tightly wrapping it with insulating cloth 30, the thermal resistance between the multiple layers of material that can exist in traditional heating components is reduced. This means that heat is transferred to the hair more smoothly, improving heating efficiency. Furthermore, the butterfly-shaped or spiral-shaped heating layer 20 is evenly distributed across the outer surface of the heat conductor 10, ensuring uniform heat distribution throughout the entire body. This design avoids the localized overheating and uneven heating issues that can occur in traditional heating components. Furthermore, uniform heating is crucial for many applications, especially those requiring precise temperature control and avoiding overheating damage. This heating component design provides stable heating and improves heating quality. Furthermore, the insulating cloth 30 not only contacts the hair to transfer heat but also provides critical insulation protection, effectively preventing safety issues such as current leakage and short circuits, ensuring the safety and reliability of the heating component during use. Furthermore, wrapping the heating component with insulating cloth 30 reduces the risk of electric shock due to heating component failure or misoperation, providing an important safety guarantee for users.

[0033] In one embodiment, the thickness of the heating layer 20 is 0.1-0.2 mm.

[0034] Specifically, the thickness of the heating layer 20 is a key factor influencing heat conduction efficiency. When the thickness of the heating layer 20 is controlled within the range of 0.1-0.2mm, it effectively reduces thermal resistance, allowing heat to be transferred more smoothly to the heated object (such as hair). Furthermore, a thinner heating layer 20 responds more quickly to changes in current, generating heat rapidly. This helps increase heating speed, allowing the heat conductor 10 to reach the desired temperature more quickly. Furthermore, the uniformity of the thickness of the heating layer 20 is crucial for heating uniformity. When the thickness of the heating layer 20 is controlled within the range of 0.1-0.2mm, it ensures uniform heat distribution across the entire heat conductor 10, avoiding localized overheating or uneven heating. Furthermore, a thinner heating layer 20 reduces thermal stress caused by temperature fluctuations, thereby reducing the risk of damage to the heating component due to thermal stress. By optimizing the thickness of the heating layer 20, the heating component can maintain stable performance over long periods of use, thereby extending its service life.

[0035] In one embodiment, the heating layer 20 is made of silver paste.

[0036] Specifically, both the upper and lower layers of the silver paste are sprayed with an insulating glaze layer. The glaze layer needs to be sprayed on the heat conductor 10 first for insulation, then the silver paste is printed, and after the silver paste is baked and dried, the glaze layer is sprayed again for insulation protection. Silver paste is a material with high electrical conductivity, and the heating layer 20 made of silver paste can ensure smooth flow of current in the heating layer 20, reduce resistance loss, and thus improve the conversion efficiency of electrical energy to heat energy. In addition, silver paste has excellent thermal conductivity, which can quickly transfer the generated heat to the heat conductor 10, which makes the heating layer 20 quickly respond to current changes and achieve rapid heating. In addition, silver paste has good fluidity and plasticity, and can be made into a uniform and thin heating layer 20, which helps to ensure uniform distribution of heat on the entire heating layer 20 and avoid the problem of local overheating or uneven heating. In addition, silver paste has good oxidation resistance and can be used at high temperatures for a long time without oxidation, which helps to prolong the service life of the heating assembly.

[0037] In an embodiment, the thickness of the insulating cloth 30 is 0.2-0.3mm.

[0038] Specifically, the main function of the insulating cloth 30 is to provide electrical insulation to prevent the current from directly passing through the heating layer 20 and contacting the heated object (such as hair, skin, etc.), thereby avoiding electrical safety accidents. A thickness of 0.2-0.3mm is sufficient to provide sufficient insulation strength to ensure that current leakage does not occur under normal use conditions. In addition, while providing electrical insulation, the insulating cloth 30 also has a certain thermal resistance, and a thickness of 0.2-0.3mm can minimize the obstruction to heat transfer while ensuring insulation performance. The insulating cloth 30 of this thickness helps to establish an effective heat conduction path between the heating layer 20 and the heated object, while allowing heat to be dissipated to the surrounding environment through the insulating cloth 30. In addition, the appropriate thickness of the insulating cloth 30 can ensure that heat is not excessively lost to the surrounding environment when being transferred to the heated object, thereby improving heating efficiency. In addition, the thickness of the insulating cloth 30 of 0.2-0.3mm can provide sufficient wear resistance to prevent damage caused by friction, scratching and other physical factors during use, which helps to prolong the service life of the heating assembly.

[0039] In an embodiment, the insulating cloth 30 is made of fireproof fiber.

[0040] Specifically, the fireproof fiber has excellent high-temperature tolerance, can maintain structural stability in high-temperature environments, and is not easy to burn or melt. This enables the insulating cloth 30 made of fireproof fiber to provide an effective fire barrier in the heating component to prevent the risk of fire caused by high temperature. In addition, the insulating cloth 30 made of fireproof fiber has a high electrical insulation level, which can effectively isolate the current and prevent electrical short circuits or electric shock accidents, which is crucial to ensuring the safe operation of the heating component. In addition, the fireproof fiber can still maintain stable electrical properties at high temperatures and will not cause the insulation performance to deteriorate due to temperature changes. This enables the insulating cloth 30 to maintain its electrical insulation performance in various harsh environments. In addition, the insulating cloth 30 made of fireproof fiber has good wear resistance and can resist physical damage such as friction and scratches, which helps to extend the service life of the heating component and reduce maintenance costs. In addition, fireproof fiber generally has good corrosion resistance to a variety of chemicals and can maintain stable performance in harsh environments. This enables the insulating cloth 30 to maintain its physical properties and insulation properties in various corrosive environments.

[0041] See also Figure 1 and Figure 2 In the first embodiment shown, the heat conductor 10 is further connected to a plastic bracket 40 . Snap-fit ​​grooves 11 extend from both sides of the heat conductor 10 , and the plastic bracket 40 is provided with snap-fit ​​protrusions 41 corresponding to the snap-fit ​​grooves 11 .

[0042] Specifically, by extending the snap-in grooves 11 on both sides of the heat conductor 10 and providing corresponding snap-in protrusions 41 on the plastic bracket 40, the snap-in fixation between the heat conductor 10 and the plastic bracket 40 can be conveniently achieved. This connection method is not only simple and quick, but also ensures a firm connection between the two, preventing loosening or falling off during use. In addition, the plastic bracket 40, as a supporting structure for the heat conductor 10, can disperse the heat and pressure generated by the heat conductor 10 during operation, thereby protecting the heat conductor 10 from damage; at the same time, the supporting function of the plastic bracket 40 can also improve the stability and reliability of the entire heating component. In addition, the connection method using the snap-in grooves 11 and the snap-in protrusions 41 can greatly simplify the installation process between the heat conductor 10 and the plastic bracket 40. No additional fasteners or tools are required. Fixation can be achieved by simply aligning the snap-in grooves 11 with the snap-in protrusions 41 and gently pushing them in. This not only improves installation efficiency but also reduces installation costs.

[0043] In the first embodiment, the heat conductor 10 is in a plate shape and can be used in the field of hair straighteners.

[0044] See also Figure 3 and Figure 4In the second embodiment shown, the heat conductor 10 includes a first heating element 12 and a second heating element 13. The first heating element 12 and the second heating element 13 are combined to form a cylindrical shape. The outer surfaces of the first heating element 12 and the second heating element 13 are provided with the heating layer 20, and the outer side of the heating layer 20 is wrapped with the insulating cloth 30.

[0045] Specifically, the first heating element 12 and the second heating element 13 are combined to form a cylindrical shape. This structure contributes to the uniform distribution and rapid transfer of heat. The cylindrical structure allows heat to be evenly dissipated along the circumferential direction, avoiding the problem of local overheating or uneven heating. In addition, a heating layer 20 is provided on the outer surface of the first heating element 12 and the second heating element 13, which means that heat can be dissipated from two directions at the same time. This double-sided heating design further improves the heating efficiency and shortens the heating time. In addition, by combining the first heating element 12 and the second heating element 13 together to form a cylindrical shape, the structural stability of the entire heat conductor 10 can be enhanced. This combined structure can resist external impact and vibration, and prevent the heat conductor 10 from deformation or damage during operation.

[0046] In one embodiment, the two ends of the heat conductor 10 are respectively provided with an end cap 50 and a tail cover 60 .

[0047] Specifically, the end cap 50 and the tail cap 60 are usually made of insulating materials, such as plastic, ceramic or rubber, and they are tightly mounted on both ends of the thermal conductor 10, which can effectively prevent the current from leaking directly from the thermal conductor 10 to the external environment, thereby ensuring electrical safety. In addition, when the thermal conductor 10 is working, if its two ends are not properly insulated, it is easy to come into contact with the external conductor and cause a short circuit. The presence of the end cap 50 and the tail cap 60 can effectively avoid this situation from happening, protecting the normal operation of the thermal conductor 10 and the entire circuit system. In addition, the end cap 50 and the tail cap 60 not only play an insulating role, but also provide the necessary mechanical support for the thermal conductor 10. They can ensure that the thermal conductor 10 maintains a stable shape and position during installation and use, and prevent damage caused by vibration or external force impact.

[0048] In the second embodiment, the heat conductor 10 is cylindrical and can be used in the field of hair curlers.

[0049] In one embodiment, the insulating cloth 30 is bonded to the thermal conductor 10 .

[0050] Specifically, the primary function of the insulating cloth 30 is to provide electrical insulation protection, preventing electrical faults such as current leakage and short circuit from occurring. By firmly bonding the insulating cloth 30 to the heat conductor 10, a tight contact between the two can be ensured, effectively isolating the current and preventing it from leaking to the external environment. This firm connection not only improves electrical safety, but also guarantees the reliability and durability of the insulation performance. In addition, the tight bonding between the insulating cloth 30 and the heat conductor 10 can maximize space savings. By directly bonding the insulating cloth 30 to the heat conductor 10, the additional space required by traditional connection methods, such as the space occupied by fasteners such as bolts and nuts, can be eliminated, which not only optimizes the design, but also improves space utilization.

[0051] In an embodiment, the heat conductor 10 is made of aluminum or iron material.

[0052] Specifically, aluminum is a metal with high thermal conductivity, which can quickly convert electrical energy into heat energy and uniformly transfer heat to the heated object, making the aluminum heat conductor 10 have a significant advantage in heating efficiency. In addition, aluminum has relatively low density but high strength, which allows the aluminum heat conductor 10 to maintain high performance while reducing the overall weight of the device, making it easier to carry and install. In addition, aluminum has good corrosion resistance and oxidation resistance, and can maintain stable performance in harsh environments for a long time, making the aluminum heat conductor 10 more durable in outdoor or humid environments. In addition, aluminum has good ductility and plasticity, making it easy to process and shape, which allows the aluminum heat conductor 10 to be customized according to different application requirements.

[0053] Specifically, iron is also a metal with good thermal conductivity, although its thermal conductivity is slightly lower than that of aluminum, it still performs well in many heating applications. The iron heat conductor 10 can stably convert electrical energy into heat energy and provide uniform heating effect. In addition, iron has high strength and good durability, which allows the iron heat conductor 10 to maintain stable performance under heavy load or long-term work, and is not easily damaged. In addition, compared with other metal materials, iron has lower cost, which makes the iron heat conductor 10 have an advantage in price. For applications with limited budget or the need for mass production, the iron heat conductor 10 is an economical and practical choice.

[0054] The utility model discloses still disclose a hairdressing device, including the heating assembly as described above.

[0055] Specifically, by providing a heating component, that is, by printing the heating layer 20 directly on the outer surface of the heat conductor 10 and tightly wrapping the insulating cloth 30, the thermal resistance between the multiple layers of materials that may exist in the traditional heating component is reduced, which means that heat can be transferred to the hair more smoothly, thereby improving the heating efficiency of the hair styling device; in addition, the butterfly-shaped or spiral-shaped heating layer 20 is evenly distributed on the outer surface of the heat conductor 10, ensuring that the heat is evenly distributed on the entire heat conductor 10. This design avoids the problems of local overheating or uneven heating that may occur in traditional hair styling devices.

[0056] Specifically, hair styling tools include hair straighteners and hair curlers, which will not be elaborated on here.

[0057] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
