Heating insole with good heating performance

Abstract

The invention discloses a heating insole with a good heating performance, and belongs to the technical field of insoles. The heating insole comprises a surface layer, a bottom layer, a power supply assembly, a heating assembly and a heat preservation assembly, the power supply assembly, the heating assembly and the heat preservation assembly are all arranged between the surface layer and the bottom layer, a containing groove is formed in the heat preservation assembly, the power supply assembly is installed in the containing groove, and the thickness of the power supply assembly is not larger than the depth of the containing groove. The heating assembly comprises a composite carbon nano heating film, and the composite carbon nano heating film is made of a Sb-doped tin oxide carbon nano composite material. The containing groove is formed in the heat preservation assembly, the battery can be installed in the containing groove, the situation that the flatness of the insole is affected due to the fact that the battery protrudes in the insole is avoided, and the use comfort of the insole is improved; an opening is formed in the bottom layer of the insole, the battery can be taken and placed through the opening, and replacement of the battery is facilitated; and an elastic layer is arranged on the heat preservation assembly, and the heat preservation assembly has excellent elasticity and heating and heat preservation performance.

Description

technical field [0001] The invention belongs to the technical field of insoles, and in particular relates to a heating insole with good heating performance. Background technique [0002] Insoles are common items in people's lives, which can make shoes more comfortable to wear, and also have the function of preventing cold and keeping warm. In winter, weather is cold, and common shoe-pad can not satisfy the requirement of cold-proof and warm-keeping, so a kind of thermal insulation shoe-pad has appeared on the market. Existing thermal insulation insoles all realize the heating function by arranging heating sheets or heating films in the insoles, and then energizing the heating sheets or heating films through batteries. Since the battery continues to supply power during the heating process, the capacity of the battery should not be too low, and the volume of the battery should not be too small. If the battery is built into the insole, there will be large or small bulges in th...

AI Technical Summary

Problems solved by technology

Since the battery continues to supply power during the heating process, the capacity of the battery should not be too low, and the volume of the battery should not be too small. If the battery is built into the insole, there will be large or small bulges in the insole, which will affect the comfort of wearing; , due to the continuous power supply of the insole, it is necessary to replace the battery of the insole from time to time, and the existing heat-insulating insoles all have the problem of inconvenient replacement of the battery; again, the heating performance of the heating film of the existing heating insole is generally poor, and the heating is slow, and the insole The insulation effect is greatly reduced
