Hand heating device applied to public area

Abstract

The invention aims to solve the problem that hands are not easy to warm in the prior art, and discloses a hand heating device applied to a public area, wherein the device comprises a bracket; a base is fixedly mounted at the lower end of the bracket, a motor is fixedly mounted in the middle of the lower surface of the bracket, and a rotating shaft is mounted in the middle of the motor; the surface of the rotating shaft is fixedly sleeved with a cam, the side face of the cam is provided with a guide wheel, the side face of the support is evenly provided with guide rings, the guide rings are internally sleeved with sliding rods, the lower ends of the sliding rods are fixedly connected with push plates, the top ends of the sliding rods are fixedly connected with connecting rings, and the upper surface of the bracket is evenly provided with mounting bases; and a guide rod is mounted on the upper side of each mounting seat, a pull ring is fixedly connected to the top end of each guide rod, a lantern ring sleeves the lower side of the surface of each guide rod, and a spiral spring is connected to the upper end face of each lantern ring. According to the invention, the principle of generating heat by friction is reasonably utilized, hands of people can be warmed in a public area, and meanwhile, the safety is relatively high.

Description

technical field [0001] The invention relates to the field of heating, in particular to a hand warming device applied in public areas. Background technique [0002] Hand warmer is an automatic heating and health care product developed by using physical and chemical principles. It has multiple functions such as automatic heating, physical therapy and health care. This product is very popular for its novel and unique advantages such as automatic heating, fun, and practicality. Hand warmers can be roughly divided into three categories, one is a hot water bag, which heats up by heating water or plugging in electricity; the other is to generate heat through chemical reactions; the third is to use the lithium battery function, and the internal heating sheet generates heat. [0003] Although the hand warmer can warm hands to a certain extent, there are many safety accidents in the hand warmer. The hand warmer in the form of a hot water bottle will make the water boil when it is heat...

AI Technical Summary

Problems solved by technology

[0003]Although hand warmers can warm hands to a certain extent, there are many safety accidents in hand warmers. Hand warmers in the form of hot water bottles are heating Sometimes the water will boil. If the power is not cut off on time, the hand warmer will explode, and the heat preservation time is limited. If you go out to take a bus or wait outdoors, it is not easy to carry the hand warmer, and the hand warmer The temperature will also drop rapidly, and the effect of warming hands will not be achieved, especially when waiting for the bus at the bus stop, it is very cold and difficult to heat. Therefore, it is urgent to design a hand warmer for application in public areas device to address the deficiencies of the prior art
