Refrigeration and heating device capable of freely switching according to human body outline shape

Abstract

The invention discloses a refrigeration and heating device capable of freely switching according to a human body outline shape, belongs to the technical field of medical care or beautification devices, and solves the problems in the prior art that a cold application device and a hot application device are complex in operation and inconvenient to carry, can not freely switch between coldness and heat and can not guarantee the sustainable supply of a cold source and a hot source. The refrigeration and heating device adopts the technical scheme that the refrigeration and heating device comprisesa plurality of unit bodies, wherein each unit body is respectively provided with a slide rail and a slide block, the slide rail of each unit body is connected with the slide block of another unit bodyin an assembly way, the top end and the bottom end of each unit body are respectively provided with a first metal body and a second metal body; an insulator, an N-type semiconductor, a third metal body and a P-type semiconductor are arranged between the first metal body and the second metal body; the top end of the N-type semiconductor and the bottom end of the first metal body are fixedly connected, and the bottom end of the N-type semiconductor is fixedly connected with the top end of the second metal body; the third metal body is fixedly arranged below the insulator; the P-type semiconductor is fixedly arranged below the third metal body; the top end of the P-type semiconductor is fixedly connected with the bottom end of the third metal body, and the bottom end of the P-type semiconductor is fixedly connected with the top end of the second metal body.

Description

technical field [0001] The invention relates to the technical field of medical or cosmetic devices, in particular to a refrigeration and heating device that can be freely transformed according to the contour shape of a human body. Background technique [0002] In daily life, due to the stimulation of the external environment, people occasionally have fever and other diseases. At this time, people start to use physical cooling methods, using cold towels to cool their foreheads to cool down; or people do other strenuous activities such as walking and running. When exercising, there will occasionally be muscle spasms and joint swelling caused by sprained feet. For muscle spasms, people will use hot towels to apply hot compresses to the muscle spasms, which can relieve muscle spasms, dilate blood vessels, improve local blood circulation, and promote local metabolism. ; For joint swelling caused by sprained feet, people will use cold towels to apply cold compresses to the swollen...
