New Project

This is my new project, a small, portable, rechargeable smoke machine for parties and cool effects in general. I dont actually remember how i got this idea, but as soon as i did, i delved into a lot of research to make it really compact while making lotsa smoke.

Sketching

As usual, i sketched out my ideas on paper, making multiple versions each time i got a new idea. I got some input from my science teacher, as well as a few uni students, especially on the capillary action performed by the fibre glass wick and the smoke liquid to be used. The sketches are attached below, with the final one being V3, as V4 is not practical to be put into action.

The genral design is to have a central encasing around a fibreglass wick, which is wrapped with nichrome wire. The bottom of the fibreglass wick is dipped slightly in the liquid from the reservior, relying upon the capillary action to lift the liquid. The nichrome wire is then heated up, evaporating the mixture into plumes of food safe smoke, blown out by the diaphragm pump.The liquid mixture that i have decided upon is a 50//50 mix of Propylene glycol and Glycerin, which is food safe and easy to use and make.

CAD 

I have done most of the CAD, and plan to have a few parts machined out of aluminum since plastic isnt the best for heat or storing liquids. I still am yet to add threads, since i dont know how to do that in Onshape, so please reach out to me if you know how to, i would really appreciate it. (Ive tried it a lot, and got it wrong every time).

Thank you!

Thank you for reading this if you got this far, hope you liked the project! Ill be posting an update soon!
