Title:
AIR GUN WELDING PEN
Document Type and Number:
WIPO Patent Application WO/2023/056804
Kind Code:
A1
Abstract:
An air gun welding pen, comprising a pen body (1) having a hollow cavity, an air passing pipe (2) arranged in the pen body at an interval, a thermal insulation layer (3) filled in a gap between the pen body and the air passing pipe, and a metal needle (4) connected to the air passing pipe. The air passing pipe comprises a cylindrical air passing pipe body (21), an air intake portion (22) formed at one end of the air passing pipe body, and an air output portion (23) formed at the other end of the air passing pipe body and having a funnel shape (7). The metal needle is connected to the air output portion, an air output end (5) is arranged at the junction between the air output portion and the metal needle, and the air output direction of the air output end is consistent with the direction in which the metal needle points. The air gun welding pen has a good thermal insulation effect, providing the funnel-shaped air output portion enables a heat flow to be gathered, the reliability of a PCB is improved, the welding pen has a small overall size and is easy to operate, and the risk of scalding is reduced.
