Embodiment 1

[0024] The present invention is a kind of miniature electric heater, see figure 1 As shown, this is the first embodiment of the present invention. In this embodiment, the miniature heater includes: a thin sheet 1 made of conductive material. In the first embodiment, the sheet 1 can be made of a high-resistance alloy material, such as a nickel-chromium alloy material. Of course, other conductive and heating sheets can also be used.

[0025] Electrode areas 11 and 12 are provided at the beginning and end of the sheet 1, through which the sheet is connected to a circuit to generate heat, and the area between the electrode areas 11 and 12 of the sheet 1 is provided with a Through holes 10 distributed in an array. The through hole 10 is formed by direct punching, or laser cutting, or chemical etching.

[0026] According to different materials, the thickness of the sheet 1 is 0.1-1 mm, and the diameter of the through hole 10 is 0.1-5 mm.

[0027] See figure 2 As shown, this is ...

Abstract

The invention discloses a method for changing heating temperature in an electric heating membrane region, and a miniature electric heating piece produced by utilizing the method. The method is characterized in that through holes are formed in a heating region of an electric heating membrane, and the heating temperature of the region is changed through controlling density or hole diameter sizes ofthe through holes in different regions. The miniature electric heating piece comprises a thin sheet material made of a conductive material, wherein an initiating end and a tail end of the sheet material are provided with electrode regions, the sheet material is accessed to a circuit to generate heat by means of the electrode regions, and through holes distributed in an array are formed in a regionbetween the electrode regions of the sheet material. The method disclosed by the invention is simple, the process is simple, the miniature electric heating piece has the advantages of fast heating speed compared with a heating piece product, and the heating speed of the miniature electric heating piece is at least doubled compared with a whole piece of heating sheet material without forming through holes; in addition, the heating is even, and the whole heating sheet material can heat evenly.

Description

Technical field: [0001] The invention relates to the technical field of electric heating films, sheets and coating products, in particular to a method for changing the regional heating temperature of electric heating films and miniature electric heating sheets produced by the method. Background technique: [0002] The hair roll that current electric curling hair is used is a cylinder, needs to produce the temperature of about 200 degrees Celsius during its work, thereby makes hair setting. The current heating method is mostly electric heating rod, which has high energy consumption and slow heating. If this heating method adopts a wired power supply method, it will not cause too much impact on the user. But if it is designed as a mobile product (powered by its own battery), this heating method will cause too much energy consumption (the power of a conventional curling iron is 100-400W), resulting in a very short use time of this mobile product. In order to adapt to the deve...
