Electric soldering iron with forked suction pipe for removing soldering smoke and cooling the handle of the soldering iron

In an electric soldering iron of the type comprising a hollow casing including a hand-hold portion at one end and a soldering bit at an opposite end, said bit being supported by a tubular electric heater holder longitudinally aligned between the bit and the casing and holding an electric heater therein permitting said soldering bit to be heated by said electric heater for the process of soldering, the improvement comprising a suction pipe holder securing a forked suction pipe having a pair of intake ports and an outlet port to said electric heater holder, wherein said suction pipe holder is made from a curved plate secured to said electric heater holder by screw means;

• said forked suction pipe is comprised of a main pipe defining one of said intake ports at one end and said outlet port at its other end and a branch pipe connected at one end to said main pipe and having a second end defining the other intake port, the forked pipe being secured to said suction pipe holder by screw means with said outlet port thereof being connected to an induced-draft fan assembly through a flexible air pipe, said other intake port of said suction pipe being connected to said hand-hold portion of said hollow casing by a heat-resisting hose and said one of said intake ports being disposed adjacent to said soldering bit, said hand-hold portion of said hollow casing having an air inlet to allow ambient air to be drawn therethrough by the suction pipe.
