Cold -proof shoes of piezoelectricity electricity generation heat production

The utility model relates to a cold -proof shoes of piezoelectricity electricity generation heat production belongs to cold -proof shoes field. The utility model discloses establish the cavity body in the sole, the internal piezoelectricity electricity generation piece of establishing of cavity, piezoelectricity electricity generation piece enlargies the module through piezoelectricity to be connected with DC power supply, it has the recess of placing the heating wire to open on the sole, and the heating wire is connected with DC power supply. The utility model discloses be suitable for the outdoor crowd who walks, also be applicable to the fixed crowd in post. When people are wearing this shoes walking, producing voltage by piezoelectricity power generation facility and storing, act on the heating wire and generate heat, do not consume the other energy, unnecessary electric energy is stored in the lithium cell of taking certainly, when human body then available lithium cell power supply heating when static, can effectually prevent that cold from huring the foot. Because temperature control device's real time monitoring for the foot temperature is in optimum temperature all the time, therefore this shoes design is very humanized, and the dress is very comfortable, and this product has reached the winter protection health preserving effect to people.
