Far-infrared film structure and manufacture method thereof

Abstract

The invention relates to a far-infrared film structure and a manufacture method thereof. The far-infrared film structure comprise an oxide film, an electrothermal film and a block layer; the oxide film is formed by an oxide gel formed by mixing oxide powder with a sol; the electrothermal film is combined onto the oxide film, forms a flexible thin plate together with the oxide film, and comprises a flexible electrothermal sheet and at least two electrodes, the flexible electrothermal sheet is coated with a conductive nanometer carbon powder coating, and the two electrodes are arranged separately, buried in the flexible electrothermal sheet and electrically with the flexible electrothermal sheet; and the block layer coats the surface, far from the oxide film, of the electrothermal film, and is made of at least one of a heat insulation material and an insulation material. Thus, the far-infrared film structure can bend to fit with the human-body curve, includes a high content of oxide powder, is convenient to use, and has a high radiation rate of far infrared rays.

Description

Technical field [0001] The present invention relates to a medical and health care device that generates far infrared rays, in particular to a far infrared film structure and a manufacturing method thereof. Background technique [0002] Far infrared (Far Infrared, FIR) refers to light waves in the region of 8,000 to 14,000 nm on the spectrum. Far infrared can resonate with human molecules to promote blood circulation, accelerate metabolism, increase body immunity, and balance pH in the body Etc. Therefore, medical and healthcare devices on the market have also begun to be used in combination with far infrared rays. [0003] The heating element in the medical and health care device is taken as an example. The heating element mainly includes a substrate and an electric heating film combined on the substrate to achieve a hot compress effect. In order to use the heating element in combination with far infrared rays, the substrate is usually radiant. A rigid board made of infrared ore ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned heating element has the following disadvantages: First, when the base material is a hard plate made of ore or ceramic material that can emit far infrared rays, the hard plate cannot be bent to fit the curve of the human body, causing users to feel inconvenient to use ; Two, when the base material is a soft board with ore or ceramic powder that can emit far infrared rays, because the soft board maintains sufficient softness and flexibility, the content of the ore or ceramic powder is reduced, or Fixed ore or ceramic powder is fixed by coating or gluing, which affects the efficiency of far infrared rays
