Abstract

The utility model discloses a contact type cold and hot instrument, which relates to the technical field of temperature control devices, and comprises a cambered surface contact element, a fan and a shell, a handle is arranged on the shell to replace the existing fixing mode of an auxiliary lifting buckle and a bandage, the cambered surface contact element can be pushed to be in contact with the surface of a human body by holding the handle with a single hand, the use is more convenient, and the cost is lower. In addition, air circulation structures such as ventilation holes in the shell cannot be shielded in the using process, and normal refrigeration of the fan is better facilitated; meanwhile, the power supply is arranged in the handle, so that heat generated when the power supply works can be effectively prevented from influencing the refrigeration effect, air can normally penetrate through the ventilation structure on the shell, and the optimal heat dissipation effect of the temperature-controllable element is further ensured.
