Hello,
I made another prototype.
combines the advantages of mflb:
-conduction- the herbs are heated mainly on a sieve and do not burn,
-the contents of the chamber can be evenly evaporated by shaking,
-larger amount of herb -excellent and strong taste,
-free way- minimal resistance to inhalation,
-antication to heat up and inhale the collected steam after a while,
-large variability of personal preferences
-grinder of mflb can be used
and advantages of the dreamwood convection vaporizer:
-convection heating by air flow through a spiral under the sieve
-real incredible battery life
-Super user friendliness control mode
-relatively discrete size
-possibility of setting power and all the advantages of battery mode
-Simplicity, minimal production costs and environmental friendliness of the product-wood, no plastics
-convection and the possibility of combinations of evaporative cooling with air under the atomizer or in the chamber or on the mouthpiece
-possibility of diy - spirals, design, material, size, microdosing
You can still research the shape, length and diameter of the spiral for the power-to-battery ratio. But I'm not an electrician, so I don't know anything about it.
here i used kanthal wire, diameter 1mm and it gives a resistance of about 0.20 and it works great around 20-40wat. I can use a finer mesh for the sieve, but I don't have any. here i used two steel strainers over each other and it works. the spiral does not heat up extra power and produces heat for convection and at the same time heats the sieve-conduction.
so far it works fantastically, it is possible that over time I will come across some disadvantages. if I don't reckon that it counts on some small dose of the learning curve, then I don't see the disadvantages yet.
I don't know how much some kanthal and steel crap can be released, but since in this case they both don't get as hot as dreamwood, so I'd say it probably won't get any worse ....
if you are interested or have some personal experience, I will be happy for your feedback ....
let's all vaporizing people come together
