To provide an air gun device installed in a bathroom or the like and capable of releasing compressed air of an optional temperature with optional strength at an optional timing.

The air gun 11 is constituted by mounting an elastic film 14 composed of an elastic body inside of a case 12 having a space for storing the air inside, and an opening portion 13 for releasing the air inside to the external, and the compressed air is generated by applying impact shock to the elastic film 14, and unidirectionally released from the opening portion 13 in the bathroom. Further the case 12 is provided with a Peltier element 18 in a state of being connected with an internal heat exchanger 19 mounted in the case 12, and electric power is supplied to the Peltier element 18 to allow the Peltier element 18 to absorb or generate heat, thus the air in the case 12 can be cooled or heated through the internal heat exchanger 19.
