Portable smoking device (SMD version)

Overview

Portable smoking instrument, absorbs and purifies smoke during welding to protect human health

Choose a 7cm fan with colorful lights, 18650 charging circuit and charge and discharge protection circuit.

Proofing (make two models in total. One panel, four sides of a shell)

Break off the PCB of the casing (there are two long ones and two short ones (the two short ones are different))

welded panel

Weld the shell and connect it with tin. The surfaces must be directly vertical.

Welded shell

Welding fan (pay attention to the direction the fan turns to suck the smoke away, and pay attention to the polarity of the fan power cord)

Weld the positive terminal of the battery to B+ and the negative terminal to B-, install the protective net and screws, and you're done.
