Take a look at our thoughts
The convection principle of HERBIE:
The cold air is aspirated through the outer housing and hits the inner housing (lower blue arrow).
From there, the air streams downwards between the housings (orange arrow). The air absorbs heat from the outer housing meanwhile. This has two advantages: Firstly, the air is preheated by the outer shell. Secondly, which is clearly the larger advantage, the air absorbs the heat of the housing. This in turn has the effect that the housing is actively cooled.
Now the preheated air reaches the inside of the Herbie (second orange arrow) and hits the glowing mesh (red arrow). From there it streams through the herb chamber (second red arrow), which has a bottom and a top mesh to keep the material in place.
Now the secondary air guide comes into play. At the same time fresh cold air is forced into the upper area (upper blue arrows) by underpressure. The “secondary air” mixes with the warm vape and the result is a pleasant temperature and a non-itching vaping experience.
The conduction principle of Herbie:
The glowing mesh emits radiant energy. This energy is absorbed by the shell, which then heats up. Due to the low thermal conduction coefficient of metal, the herb chamber heats up very quickly. The ingredients are dissolved from the herbs by the warm walls of the chamber.
The two-chamber principle:
Because there is air between the shell and the housing and air is known to be a very good thermal insulator, the outer housing is protected from the hot air and does not heat up so much. In addition, the radiant energy is already absorbed by the shell. As a result, this energy does not hit the housing and is not heated by the radiation.
As mentioned above, metal is a good thermal conductor. Unfortunately, the temperature of the shell is not only directed to where it is needed to be (herb chamber), but also towards the base. This detail is also considered by us. In the lower part of the heating chamber, the air duct (second orange arrow) allows a seperation (first orange arrow) between the shell and the base. That again has three advantages:
Advantage 1: The bowl only touches the base in very small areas, which almost prevents heat conduction into the base.
Advantage 2: Because the air flows along the base, the principle of forced convection also works there. This is how the base is cooled.
Advantage 3: The functional design of the edges (CFD calculated) of the air duct (second orange arrow) creates 8 standing vortices in the inner chamber (two per air duct). The increased turbulent kinetic energy of the air absorbs the energy of the mesh more efficiently than a laminar flow. This way it heats up much faster, which in turn increases the battery life.
If you look at competing 510 vaporizers, you can see that we completely dispense with a heat sink in the direction of Mod. This is because our concept is so well thought out that a large part of the energy is absorbed by the air.
Other 510 vaporizers have the base as the only metal part. Since glass and wood are very difficult to absorb energy, a large part of the energy is absorbed by the base. Since it is made of metal, it conducts the heat directly into the battery mod, which can cause damage if used without heat sink.
Glass also has the disadvantage that it is very sensitive to shocks. If the battery mod with one of the other 510 vaporizers falls out of your hand, the inner glass usually breaks and you are forced to buy a new one. Since Herbie is completely made of stainless steel, he has at most a slight scratch.
Is the drawing resistance too little for you (want open draw)? No problem. Turn the ring on the housing to close the aircontrol until you like it.
You don’t mind hot steam? Or you don’t want to mix your extracted vapor with fresh air? No problem: Close the secondary air system control ring.
You don’t like the supplied drip tips made of glass and plastic? No problem either. Thanks to the standardised 810 connection, you can get what you want right in the next Vapestore.
