An electric heating foot warmer capable of harvesting piezoelectric energy

Abstract

The invention discloses an electric heating foot warmer capable of collecting piezoelectric energy. The electric heating foot warmer comprises two layers of sealed cotton pads, wherein a piezoelectricenergy collecting device, a heating device, a temperature sensor and a controller are arranged in an inner cavity between the cotton pads; a protective ring sleeves the peripheries of the sidewalls of the cotton pads; a plurality of convex particles are arranged on the outer wall of the protective ring; a battery is connected to the piezoelectric energy collecting device via a lead wire, so thatthe battery can be charged; the heating device is arranged at the top of the inner cavity of the cotton pads and is connected to the battery via a lead wire; the temperature sensor and the controllerare arranged on a master control board; the temperature sensor and the battery are electrically connected to the controller; and a manual switch, which is connected to the controller, is arranged on the outer wall of the protective ring. The electric heating foot warmer provided by the invention, via a first piezoelectric mechanism and a second piezoelectric mechanism, can generate electric energyto the greatest extent; the electric heating foot warmer is simple in structure, convenient to operate and strong in applicability; and the electric heating foot warmer is applicable to various places and is suitable for large-scale development.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an electric heating foot warmer capable of collecting piezoelectric energy. Background technique [0002] With the change of life style, more and more people keep sitting for a long time in work and life, which will inevitably lead to poor blood circulation in the lower limbs, coupled with not paying attention to the movement and warmth of the feet, often making the feet cold . Especially in winter, the feet will feel uncomfortable such as freezing and numbness, and women have more cold physiques, which is more common, so heating the feet is very important. In addition, in the north of our country, the outdoor climate is very cold in winter. For people who need to be in the outdoor environment for a long time, it is especially important to keep their feet warm. When the temperature of the feet is high enough, it will drive the blood circulation of the whole body, and t...

Problems solved by technology

At present, the foot warmers on the market often use a mechanical method to drive a small generator to generate electricity. The comfort is low, the volume is too large, and it is not easy to promote. Adjustments are not very convenient to use
