A kind of explosion-protection equipment of electric warming bag,Include: an air pressure flame-proof switch,One cut-off switch and an electrothermal tube constitute conductive loops connection； Wherein,The cut-off switch more connects a power supply base； When electrothermal tube heating contains the heat-conducting liquid in what bag,Air in bag can also be heated and expand,When pressure is more than the setting value of the air pressure flame-proof switch in bag,It activates it and generates electrical signal output,It activates the cut-off switch power-off and stops heating,Reach the purpose of safety anti-explosive,The component as described in what is to contain in what electric warming bag,Therefore,Its volume is light and handy but the known fixture etc. for still having circumscribed volume huge,Using,Carry,Packaging,Transport ideal convenience.一種電暖袋的防爆裝置，包括：一氣壓防爆開關、一斷電開關及一電熱管構成電性迴路連接；其中，該斷電開關更連接一供電插座；當電熱管加熱容裝於袋內的導熱液體時，袋內的空氣亦會受熱而膨脹，當袋內壓力超過所述氣壓防爆開關之設定值時，即致動其產生電氣訊號輸出，致動所述斷電開關斷電停止加熱，達到安全防爆之目的，由於所述構件均係容裝於電暖袋內，因此，其體積輕巧無如習知尚有外接體積龐大的夾具等，使用、攜帶、包裝、運輸均較為理想方便。
