Claim:
A warmer device, comprising: a protection device having a protection cavity therein; and a rechargeable warmer bag which is arranged to be charged in said protection device, wherein said rechargeable warmer is disposed in said cavity of said protection device during charging and removed out of said protection device during operation, wherein said rechargeable warmer bag comprises: a bag defining a sealed cavity therein and receiving a predetermined amount of liquid in said sealed cavity; a heating unit which is disposed in said liquid in said sealed cavity of said bag comprising at least a heater; a charging unit, which is connected with said heating unit and positioned between said bag and said heating unit, comprising a charging connector; and a monitoring device arranged in said protection device with respect to said rechargeable warmer bag so as to monitor said rechargeable warmer bag and cut off power supply to said charging unit of said rechargeable warmer bag when said rechargeable warmer bag is over-expanded, and that when said rechargeable warmer is in use, said rechargeable warmer bag and said monitoring device are separated; wherein said protection device comprises a bottom board, a column mounted on said bottom board and a connecting pole connecting to the power, wherein said column comprises a connecting element and an actuator switch mounted on an upper side of said column, said connecting pole being pivotally connected on a top of said column, one end of said connecting pole being connected with said connecting element of said column, wherein when said rechargeable warmer bag is being charged, said rechargeable warmer bag is positioned in said protection device, and said other end of said connecting pole is connected with said charging connector, wherein said connecting pole further comprises a power plug, wherein when said rechargeable warmer bag is being charged, said rechargeable warmer bag is disposed in said cavity of said protection device and said power plug connects to said charging connector of said rechargeable warmer bag, and that, at the same time, said connecting pole is pushed down to turn on said actuator switch, and then said rechargeable warmer bag is being charged, wherein when said rechargeable warmer bag is over charged to over expand, said rechargeable warmer bag raises a top surface thereof due to the expansion to press said connecting pole to move upwardly, and then said connecting pole does not press said actuator switch but releasing said actuator switch to cut off the power supply of said rechargeable warmer bag.
