However, accidents often occur during fitness, which may cause injury, so physiotherapy rehabilitation equipment is needed for refrigeration and hot compress. Refrigeration and hot compress are physical therapy, and their principles of action, methods of use and use time are different. Refrigeration is mainly used to reduce the local temperature of the skin, make the subcutaneous blood vessels contract and reduce the blood flow, so as to relieve pain and prevent swelling. Hot compress is mainly used to promote local blood circulation of the skin, make the blood vessels dilate, speed up the blood stasis or relieve muscle pain or tension.

[0003] Generally, people use refrigerators and hot compress equipment for refrigeration and hot compress. The refrigerator, like the one disclosed in patent application 202223568040.5, is refrigerated by an ice bag. The hot compress instrument, like the one disclosed in patent application 202320223939.9, is heated by the heating of the hot compress part.

[0004] Later, a semiconductor refrigeration sheet that is easy to use appeared, and people combined refrigeration and hot compress together, so that one device can be used for both refrigeration and hot compress. For example, the portable cold and hot compress instrument disclosed in patent application 202322783493.8 includes a main shell and a handle shell. The main shell is provided with a refrigeration head, a TEC refrigeration sheet, a heat dissipation module, a ventilation duct, a fan and a perforated rear cover in the axial direction from front to back. A main control panel is provided on the inner wall of the main shell at the ventilation duct. The TEC refrigeration sheet is tightly attached between the refrigeration head and the heat dissipation module. The main control panel controls the current direction of the TEC refrigeration sheet to realize the refrigeration or heating effect of the refrigeration head. It also includes a temperature sensor arranged in the recess on the inner side of the refrigeration head. This technology takes advantage of the characteristics of the TEC refrigeration sheet, which can cool one side and heat the other side.
