Abstract

This invention is an insulated bag which is capable of heating or cooling drinks and food. In the bag fits drinks box and food box, to the outside of the boxes attached heating film or PTC plate and semi-conductor refrigerating plate. The boxes are wrapped with insulating material. To the top inside cover of the food box fixes a refrigerating fan for fast refrigeration. The power is provided by battery or outside input. The bag is outfitted with battery shortage protection unit, short circuit protection unit and over heat protection unit. A temperature controller controls heating or refrigerating to the preset temperature. When short of battery or the temperature reaches the preset one, the bag sounds correspondingly. A metal (or plastic/nylon) unloadable rack to the outside of the bag and designed according to human body back is capable of heat dissipation in hot weather.

Description

Technical field: [0001] The present invention is a kind of electric heating film (or PTC ceramic heating sheet) and semiconductor cooling sheet that can use the energy in the battery or connect the DC power supply from the outside to generate heat and cold in backpacks, satchels, and handbags. On the outer wall of the water box (water cup) and the food box, there is a multi-purpose heating and cooling insulation bag for heating or cooling water (beverage) and food. It can control the temperature of the heated and cooled water and food. Its circuit has short-circuit protection. Over-temperature protection, battery under-voltage (over-discharge) protection, can cut off the heating or cooling circuit power supply, and protect the safety of the battery pack and the entire circuit (including electric heating film and semiconductor cooling sheet). It can also use language (or music) to remind the user when the battery is under-voltage (over-discharged) or the heating and cooling tem...
