动手做了全世界第一台双向焊风枪，同时也是吸锡枪和吸耳屎枪。通电后，一面出热风，一面吸风。出热风一面作为焊锡枪和塑料焊枪使用。吸风端作为吸锡枪或吸耳屎端使用。目前好像市面上没有，希望今后能有。为了能起到吸耳屎的效果，吸风端外周有槽。

I personally made the world's first bidirectional soldering air gun, which was also used as a tin suction gun and an earwax suction gun. After being powered on, one side emits hot air while the other side sucks in air. The side that emits hot air is used as a soldering gun and a plastic soldering gun. The suction end is used as a tin suction gun or an earwax suction end. It seems that it's not available on the market at present. I hope it will be available in the future. In order to achieve the effect of removing earwax, there are grooves around the suction end.
