Abstract: A solenoid valve having an explosion-proof structure, a fuel feeding system, and a method of manufacturing the solenoid valve having an explosion-proof structure are provided. The solenoid valve having an explosion-proof structure includes: a body including a channel through which a fluid flows; a housing connected to the body and having one surface opened; a solenoid assembly arranged inside the housing and electrically connected to a controller; an armature, at least a portion of which is arranged in the channel and which opens or closes the channel by moving relative to the solenoid assembly by a magnetic field generated by the solenoid assembly; and a cover plate arranged on the one surface of the housing to face the armature.

Abstract: The present invention relates to a candle-powered lighting apparatus including: a housing which accommodates a candle; a heat absorbing plate which absorbs heat generated by the candle; a heat radiating plate which radiates the absorbed heat; a thermoelectric element which is positioned between the heat absorbing plate and the heat radiating plate, and generates thermoelectromotive force using a temperature difference between a contact surface with the heat absorbing plate and a contact surface with the heat radiating plate; a lighting unit which emits light using the generated thermoelectromotive force; and a control unit which controls an operational state of the lighting unit to an on or off state.
