Head for a heating hand tool with no temperature increase along the nozzle

摘要

The head (1) has a conduit connected to a handle of a heating hand tool by one end (21) of the conduit. The conduit comprises a fuel gas inlet (23) and a conductive wire (24) forming an electrode for a spark starter. A grid (25) is placed at another end (22) of the conduit for fixing with the starter of the spark in combustible gas flow for ignition of flame. The wire extends through the grid and out of the conduit. A burnt gas evacuation cup (4) is positioned on level of the latter end. The cup directs the burnt and heated gas such that it remains out of contact with the conduit.
