The utility model carries out segmented control on the heating power of the heating circuit, thereby reducing the current of the heating circuit and improving the safety of use; further, by adjusting the heating power of the heating circuit in segments, the heating power adjustment is more flexible and more accurate. The utility model also provides an intelligent toilet. The hair straightener heating element is a kind of high temperature resistant ceramic, surface energy flame retardant, good fire resistance, at 1200 degrees high temperature will not affect its working performance.

MCH is a new type of metal ceramic heating element with PTC effect. Compared with the traditional BaTiO_3-based PTC heating element, MCH is an environment-friendly heating element without lead. At the same time, it also has the characteristics of non-charged surface, fast heating speed, small volume, and heating temperature up to 1000 ℃. The project process uses alumina cast raw porcelain as the insulating layer and the substrate. The high-temperature metal thick film slurry is printed on one side of the raw porcelain. Then the upper and lower alumina raw porcelain are laminated, sliced, sintered at high temperature in a hydrogen furnace to form a heating element, and then the lead wire is welded to form an MCH heating element. MCH is very common in application fields. At present, it is mainly used in electric hairpins and curlers, electric heaters, electric heaters, air conditioners, air conditioners, bathroom and hot water heaters, automobile exhaust treatment device (12~24V/DC) and other fields. Insulated MCH heating element price hair straightener heating element has high hardness, excellent wear resistance, light weight and wide application range.

Practical production and a large number of studies show that: low pore rate, high density of zirconia ceramic section structure performance excellent hair straightener heating body, tell density means that the ceramic body grain closely arranged. In the external load or corrosive material erosion is not easy to form a destructive breakthrough point, hair straightener heating body and to get the density of calcium ceramic embryo, molding method is the key, zirconia ceramic molding generally using dry pressing, isostatic pressing, hot die casting and other methods. Different methods have different characteristics, the effect on the maintenance rate of ceramic sintering and microstructure will be different, hair straightener heating body generally for the shape of complex products to grouting and hot die casting process.

Hair straightener heating body according to the different materials, can be divided into alumina thermal conductive sheet, JRF alumina thermal conductive ceramic sheet and so on. The hair straightener heater is used in the electronic and electrical fields that require heat conduction, heat dissipation, insulation, high temperature resistance, and high voltage breakdown resistance, with high thermal conductivity and good stability. The alumina ceramic sheet is a high thermal conductivity, high insulation of a material. Hair straightener heating body alumina content is high, the structure is relatively dense, with special performance, so called special ceramics. The hair straightener heating body is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions are filled in the octahedral gap of the 2/3, which is the same stable α-Al2O3 structure as natural corundum, so the hair straightener heating body has high melting point, high hardness and excellent wear resistance. The surface of MCH ceramic heating element is safe and uncharged, with good insulation performance.

When the temperature around the heating element of the hair straightener exceeds the limit, its power will automatically drop to the equilibrium value, which will not cause combustion hazard and has a long life. The heating element of the hair straightener itself is oxide ceramic, which has no high-temperature oxidation defects of nickel-chromium wire, no fragile phenomena such as glass quartz tube, and long service life. In the past, the preparation parts that served as the "big responsibility" for these heating were often based on metal as the basic structural raw materials. During use, it was easy to cause oxidation of the parts due to long-term heating, which affected their service life. In order to avoid these problems, it is natural to look for alternative materials, alumina ceramics is a good choice. After printing the resistance paste on the alumina ceramic, it is synthesized by high temperature co-firing, and after the electrode and lead wire are treated, a new generation of medium and low temperature heating element-hair straightener heating element can be generated. The advantage of hair straightener heating body is easy to produce, in addition, due to mechanical molding, the edge is very smooth, will not pull the hair.

The temperature of the heating element of the hair straightener is related to the applied voltage, but has little to do with the ambient temperature. Performance of ceramic MCH heating element

The hair straightener heater has the advantages of corrosion resistance, high temperature resistance, long life, high efficiency and energy saving, uniform temperature, good thermal conductivity, fast thermal compensation speed, etc., and does not contain lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated Diphenyl ethers and other harmful substances, in line with the EU RoHS and other environmental protection requirements. The heating element of the hair straightener is a heating element made by sintering the electric heating body and the ceramic at high temperature and fixing them together. The resistance can be adjusted according to the temperature of the body, so that the temperature can be constant at the set value without overheating. It has the characteristics of energy saving, safety and long life. This kind of heater does not emit light at work, has no open flame, no oxygen consumption, soft air supply and automatic constant temperature function. Hair straightener heating body output power of 10-50 watts, you can adjust the temperature, work without light consumption, automatic switch device, high efficiency and energy saving, power saving and safety.
