Claims

[Scope of utility model registration request]

A safety device 17 is installed in communication with the can body 5, and the safety device 17 includes a valve part a equipped with an intake valve 22 that sucks in outside air when the internal pressure of the can body 5 is below a certain level, and a valve part a that is responsive to the internal pressure of the can body 5. It consists of a switching element 30 that energizes or stops energizing to necessary locations, and the switching element 30 is made of a pressurized conductive member that has a large resistance when no pressure is applied and a small resistance during machining. A water heater safety device featuring:
