Abstract
The utility model relates to an automatic burning torch after dying out, comprising a casing, a top pressure mechanism, a propellant bottle with fuel, a one-way valve, a pressure reducing and stabilizing valve, a fuel burner and an extinguishment automatic recombustion igniter. The bottom cover is arranged at the tail end of the casing. If the bottom cover is rotated anticlockwise, the top pressure mechanism can impel the propellant bottle to rise. The one-way valve is opened and simultaneously the electric source is communicated, and the combustion gas goes into the burner and is ejected by the fire hole through the propellant bottle, the one-way valve and the pressure reducing and stabilizing valve. The igniter creates electrical spark to ignite the combustion gas, and all of the processes are completed momently. By the interaction of the igniting needle and the feeling flame needle, the igniter can momently ignite automatically and prevent wind and rain when the flame is extinguished because of outside reasons. Inversely, if the bottom cover is rotated clockwise, the propellant bottle can fall down with the top pressure mechanism.
