Auto-mug

(1) Working principle: This new product is installed the refrigeration film between the inner liner and radiator,and the refrigeration film is conjointed with toggle switch.So,the refrigeration film can heat or cool inner liquid directly via control of toggle switch,and the surrounding insulation boards can keep the temperature difference of upper and lower of refrigeration film.This process achieves the effect of heating or refrigeration. (2) Temperature: The heating temperature is equal to or greater than 65°C. The refrigeration temperature is equal to or less than 10°C. (3) Applicability: This product is widely adapted to the use of low-voltage areas,especially for auto use.
