Abstract
The utility model relates to an explosion-proof thermostatic electric heating water bag, which is composed of an outer shell (1), a socket (2), an electrode (3), supports (41), (42), a valve plug (5), a core (6), a valve cap (7), a valve pin (8), a water injecting hole (9), an indicating lamp (10), and an electric conduction needle (11). Water is filled in the explosion-proof thermostatic electric heating water bag, and then the explosion-proof thermostatic electric heating water bag is powered on to store heat for heating. When the utility model is powered on to heat, as the outer shell is inflated to bulge, the electrode (41) is scattered on a water surface to power off to limit temperature. The length of the electrode (41) is changed to limit the high and low of the temperature. If the explosion-proof thermostatic electric heating water bag is powered on for a long time, the electrode (41) is repeatedly bulged (powered off); when the electrode (41) is fell down (powered on), water temperature is fundamentally constant. The utility model can not be exploded because of overheat. When air is inflated excessively, only the top end of the valve cap (7) is pressed down, and then air can be released.
