Heating unit and forming process thereof

Abstract

The invention provides a heating unit which comprises an inner heat insulation casing, a heating wire, an outer heat conduction casing, an electric connection assembly and a power supply assembly, wherein the inner heat insulation casing is provided with a cylindrical outer peripheral surface; the outer heat conduction casing is fixedly arranged outside the inner heat insulation casing in a sleeving way; the electric connection assembly is fixed to the inner heat insulation casing; the power supply assembly is relatively fixed to the inner heat insulation casing; the heating wire is wound on the cylindrical outer peripheral surface of the inner heat insulation casing to form a cylindrical heating coil; the cylindrical heating coil is fixed between the inner heat insulation casing and the outer heat conduction casing; the two ends of the heating wire are connected with the electric connection assembly; and the electric connection assembly is connected with the power supply assembly. Theheating unit has the advantages that the heating surface of the heating unit is a space surface instead of a plane, so that the heating is uniform; by combining the heat insulation performance of theinner heat insulation casing and the heat conduction performance of the outer heat conduction casing, the heat can be prevented from being inwards transferred, so that the heat can be better outwardstransferred; the heat loss is little; the heating effect is good; and the heating power is greatly reduced.

Description

Technical field [0001] The invention relates to the field of massage equipment, in particular to a heating unit used for foot massage and a molding process of the heating unit. Background technique [0002] With the acceleration of life in modern society, people's bodies are prone to various fatigue and soreness due to lack of exercise. Massage on the human body can relax tense muscles, eliminate fatigue, promote blood circulation, etc., which has a good effect on health care and physical fitness. . Based on this, there are many massage devices on the market, which relax the human body and promote blood circulation by massaging the human body. Therefore, massage devices are accepted and loved by more and more consumers. [0003] Further, in order to increase the function of the massage device, some massage devices are equipped with a heating unit for massaging the soles of the feet. The heating unit is rotatably installed in the massage device. The heating unit is usually provided...

AI Technical Summary

Problems solved by technology

However, among the heating units currently on the market, they are basically planar heating, using the basic structure of heating sheets. The main material of the heating unit is usually made of non-thermally conductive materials, so the heating unit has the problem of uneven heating, which leads to poor user experience
