Abstract: An off-water shutdown protection mechanical heater includes a tube and a cap mounted to an end of the tube. The tube includes therein an off-water protection transducer, one of a relay and a TRIAC, a circuit board including a bimetal plate, and a heating element. When he off-water protection transducer detects a situation of being immersed in water, the one of the relay and the TRIAC turns on to conduct electricity and the bimetal plate detects a temperature of water and undergoes deformation by the temperature to control the heating element to generate heat or not; and when the off-water protection transducer detects a situation of being removed out of water, the one of the relay and the TRIAC turns off to cut off electricity, making the heating element not generating heat. The off-water protection transducer ensures that electricity is quickly cut off upon removal out of water.
