Ceramic thick film hair-straightening heater and preparation process thereof

Abstract

The invention discloses a ceramic thick film hair-straightening heater, which comprises a base plate layer, an insulating thick film heat conducting layer, resistance layers and electric conduction layers. The insulating thick film heat conducting layer, the resistance layers and the electric conduction layers are sequentially printed on the outer surface of the base plate layer from bottom to top; a thermally sensitive resistor (NTC) membrane layer is printed in the center of the insulating thick film heat conducting layer, a first electrode and a second electrode are arranged on the surfaceof one end of the insulating thick film heat conducting layer, and a third electrode is arranged on the surface at the other end of the insulating thick film heat conducting layer; the resistance layers are printed on the positions, on the two sides of the NTC membrane layer, of the insulating thick film heat conducting layer in a mirror symmetry mode; and the resistance layers are each of a multi-section rectangular structure, and all the sections of resistance layers are mutually connected in series through the electric conduction layers and evenly distributed on the insulating thick film heat conducting layer. The heater is simple in structure, resistant to pressure, high in heat impact resistance and simple in production process, the stability and reliability of the resistance layer structures can be guaranteed, the temperature rising time is short, the heating time is greatly saved, and the heating power is stable.

Description

technical field [0001] The invention belongs to the technical field of heaters, and in particular relates to a ceramic thick-film straight hair heater and a preparation process thereof. Background technique [0002] Hair straighteners or hair irons are widely used in the hairdressing industry. The heat energy is provided by the heating plate. The heating plate generally uses a single PTC heating element fixed in the hair straightener or hair iron to generate heat. The heating plate is fixed on the straight In the casing of the hair iron or hair iron, to avoid direct contact between the heating element on the heating plate and the hair, thereby ensuring the power supply demand of the heating element and avoiding leakage. The thickness of the traditional heating plate is relatively thick, and the volume of the hair straightener or hair perm is often large during the processing process, and the heating time is long, and there is no temperature detector designed, so that in the ...

AI Technical Summary

Problems solved by technology

The thickness of the traditional heating plate is relatively thick, and the volume of the hair straightener or hair perm is often large during the processing process, and the heating time is long, and there is no temperature detector designed, so that in the process of use, often The temperature of the heating plate will be too high during the heating process, and the shell will be damaged, which will cause great harm to the user. Therefore, it is necessary to design a direct hair heater with higher safety
