Description

    CROSS REFERENCE
  • The present application claims priority from Chinese Patent Application No. 200620067407.7 filed Nov. 9, 2006.
    • FIELD OF INVENTION
  • The present application relates to one kind of heating elements, particularly, to a thick film stainless steel heater used in the electric hair curler.
    • DESCRIPTION OF RELATED ARTS
  • In the present market, there are many kinds of heating components used in the electric hair curler, wherein the relatively representative heating components are the traditional positive-temperature-coefficient thermistor (PTC) heaters and the MCH high temperature ceramic heaters made from aluminum oxide ceramics. The common structure is that there is a groove on the aluminum plate 6, and a thermistor 7 is arranged in the groove of the aluminum plate 6, under the thermistor 7 was arranged the spring stator 8 (Please refer to FIG. 1), the spring stator 8 fixes the thermistor 7 into the inside of the aluminum plate 6 (Please refer to FIG. 2). Because the traditional PTC electric hair curler transfers heat to the yellow insulation paper through the produced PTC thermistor 7, then transfers heat to the peripheral ceramic plate or the peripheral aluminum plate 6, and the PTC heats up comparatively slowly, so generally speaking it is about 120 seconds to be able to reach 200° C.; afterwards appeared the MCH high temperature ceramic heater made by co-firing aluminum oxide ceramics at a high temperature of 1600° C. Although it could transfer heat more quickly, it wastes energies greatly. This MCH high temperature ceramic heater heats up more quickly than PTC, but it still transfers heat to the peripheral ceramic plate or the peripheral aluminum plate 6 through itself, thus it is normally about 60 seconds to be able to reach 200° C. Because of the disadvantages of high costs and long heating-up time of the above heating components, it is necessary to produce a fast-heating-up, insulating and high-voltage-resistant new product with a low product cost and a simple production craft.
    • SUMMARY OF THE PRESENT APPLICATION
  • According to the problems existed in the prior arts, the technical problem the present application aims to settle is to provide a simple-structure, low-cost, fast-heating-up, insulating and high-voltage-resistant heater structure of the electric hair curler, which is more compact and stable, and has a reliable performance, a simple production craft, no lead and toxins, and a good insulating effect.
  • In order to realize the above aim, the improved thick film heater structure of the electric hair curler of the present application is achieved by the technical solution as follows:
  • An improved thick film heater structure of the electric hair curler comprises a substrate equipped with a layer of an insulating thick film medium equipped with a layer of heating resistance equipped with an insulating coating layer, and the ends of the heating resistance are equipped with electrodes.
  • Further, the substrate is pressed from stainless steel plates, and the layer of the insulating thick film medium is applied on the base plate of the substrate by spraying.
  • Further, the electrodes and the layer of the heating resistance are printed on the layer of the insulating thick film medium.
  • The insulating coating layer equipped with the naked electrodes which are exposed outside of the insulating coating layer is printed on the layer of the heating resistance described above.
  • The stainless steel thick film heating component of the electric hair curler of the present application does not need printing and sintering many times and is prepared by just spraying an insulating layer on a surface of a curved stainless steel. The production craft is simple, moreover the product cost is low. Then on its surface is arranged the electric circuit which heats directly, another face of the stainless steel will contact hair directly. Thus the heating component can pass an insulation and high voltage test of 3750V, and does not need a ceramic or aluminum layer outside. The heat transfer is more quickly compared to those of the front two heaters, so it is only about 10 seconds to reach 200° C., which saves time for customers greatly and also the production costs for the society. Thus the cost is low, the heating up is quick, the insulation and voltage resistance is high, the production craft is simple, the manufacture is easy, the power of the heater is stable, and the service life is long.

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The present application is further exemplified by reference to the examples and the figures. The related structure of the present application mainly includes the following parts (or devices): a substrate 1, an insulating thick film medium 2, an electrode 3, a heating resistance 4, an insulating coating layer 5, an aluminum plate 6, a thermistor 7, a spring stator 8.
  • The substrate 1 is equipped with a layer of the insulating thick film medium 2 equipped with a layer of the heating resistance 4 equipped with the insulating coating layer 5, and the ends of the heating resistance 4 are equipped with the electrodes 3.
  • The substrate 1 is pressed from stainless steel plates, and the layer of the insulating thick film medium 2 is applied on the base plate of the substrate 1 by spraying; the electrodes 3 and the layer of the heating resistance 4 are printed on the layer of the insulating thick film medium 2.
  • The insulating coating layer 5 equipped with the naked electrodes 3 which are exposed outside of the insulating coating layer 5 is printed on the layer of the heating resistance 4 described above.
  • Press a stainless steel plate to be the substrate 1, and spray the insulating thick film medium 2 on the steel plate, then sinter the insulating layer in an high temperature sintering furnace at about 850° C., subsequently print the electrode 3 and the heating resistance 4 circuit, again sinter it in the high temperature sintering furnace, then print the insulating coating layer 5, thus the production of the whole product is completed. The product can withstand a voltage resistance of 3750V, and also heats up more quickly than the traditional heaters assembled by several products.
  • The production craft of the present application is simpler than that of the traditional stainless steel thick film heaters. The insulating medium used in the traditional stainless steel thick film heaters has a high cost, and needs printing and sintering many times, and could only be applied on the plane steel plates, thus has many limitations and is unable to be applied in the electric hair curler directly at all. Moreover it has a low insulation intensity, and can only withstand a voltage resistance of 1250V, which does harm to people and property easily. But about the heater of the electric hair curler of the present application, the production cost is lower, the heating up is quicker, the insulation and voltage resistance is higher, and the production craft is simpler. The new heater is prepared by adopting the stainless steel thick film heater as the substrate 1, spraying the insulating thick film medium 2 on the base plate of the substrate 1, printing the heating resistance 4, conductors, glass protection glaze and so on, then sintering. The heating device adheres to the stainless steel plate. The heater has a reliable and stable performance, no lead and toxins, and a good insulating effect, and a voltage resistance of up to 3750V. It has a simple production craft, only needs spraying once, does not need printing many times, and has a stable heating power.
  • The embodiment described above is exemplary only and not intended to be limiting. With the technical content disclosed in the present invention, one skilled in the art will carry out other part-changed or modified equivalent embodiments without departure from the content of the technical features of the present invention. Therefore these embodiments still belong to the scope of the technical features of the present invention.
