This smoker I’ve designed is in 2 types.

Type A: Is all mechanical and it can transform to type B easily!
When you pull the handgrip,diaphragm consist of several holes allow air to fill the Cylinder wiith smoke by the vacume power...when you release the handgrip,a plate beneath the diaphragm sticks to diaphragm (by spring's force) and it will push smoke away through the nozzle.

Type B: Has both mechanical and Electrical systems.
In this type you can charge your battery while you Pull and release handgrip and move piston.Mechanical energy by a dynam-motor charges batery then when you get tired you can use battery to make E.M(fan) move!
Also you can charge your battery by AC power.

Maybe you ask why 2 types?!!
The answer is simple...maybe people want a product that cost them less money and on the other hand there are some people looking for products that have more features!
Type A will cost you less money and type B has more features...This is a way you can absorb more costumers to your new designed product.
