Portable hot-air welding gun with power source

Abstract

A portable hot-air welding gun with a power source comprises a generator, a coaxial connector, an accelerating planet gear, an impeller rotating shaft, a rectification base, an impeller A, an impeller B, a rectification chamber hood, an air pipe, a welding gun head and a heating core. The generator is arranged at the tail portion of the welding gun; a rotating shaft at the front end of the generator is connected with the accelerating planet gear through the coaxial connector; the front end of the accelerating planet gear is fixed to the rectification base, and the accelerating planet gear is connected with the impeller rotating shaft; the impeller A and the impeller B are sequentially arranged on the impeller rotating shaft; the rectification chamber hood is mounted on the rectification base, and the air pipe is arranged at the front end of the rectification chamber hood; the welding gun head is arranged at the front end of the air pipe, and the heating core is arranged inside the welding gun head. According to the portable hot-air welding gun with the power source, the generator is used for emitting heat and supplying power, so that a power supply line is omitted; the welding gun is provided with the power source, convenient to carry, flexible to use and not affected by site power source conditions, energy is saved, the use cost can be effectively lowered, and the portable hot-air welding gun with the power source is worthy of vigorous popularization.

Description

technical field [0001] The patent of the present invention relates to the field of hot air guns, in particular to a portable hot air welding gun with its own power supply. Background technique [0002] Existing hot air torches are powered by power cords, and finally blow out hot air to achieve the purpose of welding plastics or waterproof membranes. Due to the different conditions on the construction site, the sizes of the buildings on the site are different, and the heights of the buildings are not equal, resulting in the need to carry a large number of power cords for use during on-site construction. Connect the power supply; in large-scale construction sites, due to the excessive resistance caused by the long power line, the voltage drops, and the heat gun cannot reach the set temperature, resulting in unreliable welding. Contents of the invention [0003] The invention aims to provide a portable hot air welding torch with its own power supply which is convenient to us...
