Detailed Description

The heating foot pad of the present invention is further described with reference to fig. 1 to 2.

The utility model provides a callus on sole generates heat which characterized by: the heating foot pad sequentially comprises a bottom layer 4, a heat preservation layer 3, a heating sheet 2 and a surface layer 1 from bottom to top.

The heating sheet 2 comprises a carbon fiber cloth 22 and a waterproof insulating layer 21 which is compounded on the front side and the back side of the carbon fiber cloth 22 and wraps the carbon fiber cloth 22; conductive strips are sewn at the edges of the left side and the right side of the carbon fiber cloth 22, conductive wires extending to the outside of the waterproof insulating layer 21 are connected to the conductive strips, and insertion ports are formed in the end portions of the conductive wires.

When the automobile heating pad is used, the heating foot pad is paved in an automobile, the plug-in interface of the conducting wire is plugged into the vehicle-mounted power supply interface, the heating function of the heating sheet 2 is achieved, and the comfort level of personnel in the automobile is improved. The heating sheet 2 is made of carbon fiber cloth 22, and has the effects of uniform heating, stable heating, high heat conversion rate, quick heating and electricity saving; the carbon fiber cloth 22 heats the human body by radiating far infrared rays, so that the comfort level of the human body is obviously improved; the carbon fiber cloth 22 can save the power consumption of a vehicle-mounted power supply while generating heat, and reduces the influence of the carbon fiber cloth on the normal running of the vehicle, particularly an electric vehicle; the carbon fiber cloth 22 is a whole piece of cloth which can conduct electricity and is flexible, so that damage caused by breakage does not exist, and normal electricity conduction and heating of the carbon fibers cannot be influenced even if part of the carbon fibers are broken; the heat preservation layer 3 can achieve an effective heat preservation effect, so that heat radiates upwards, the problem that the heat scatters and dissipates downwards is avoided, an effective heating effect is achieved for feet, and electric energy is further saved.

In the present embodiment, the carbon fiber cloth 22 is a carbon fiber woven fabric disclosed in patent document No. CN 109457430A.
