This is the end where you inhale your vapor from.
Mouthpieces are the main point of your interaction with a JUUL.
Sadly, JUUL pen is a totally sealed environment, so you can’t easily replace the mouthpiece if you want to.
It is meant to be discarded once it runs out of e-liquid.
Because the product isn’t designed to last long, the mouthpiece isn’t intended to be replaceable either.
#2 Absorbent Pad
The absorbent pads are small cotton pads inside the JUUL just beneath the mouthpiece.
These pads absorb any droplets coming through with the vapor.
This ensures that your vapor is clean and without any pesky droplets.
You can actually replace these with regular cotton balls for those of you who like to open their JUUL pens, and they will work just the same.
Or you could also set them out to dry and then put them inside.
#3 Air Path
The Airpath is the cylindrical passage through which the vapor travels towards the mouthpiece.
This is connected to the tank cap through which the vapor travels to the absorbent pads.
The absorbent pads absorb any stray droplets before the vapor reaches the user via the mouthpiece.
The Air Path gives the vapor a proper airflow channel to go towards the user.
The Air Path design allows the JUUL pen to be more consistent with each puff because the inhaler has a constant volume.
Each puff contains a similar volume of vapor depending on how long the puff is. This is also sometimes known as the chimney.
#4 Wick Housing
Wick is the material that absorbs the e-liquid from the tank and draws it to the coil to be heated.
A range of different materials is used for the wicks in e-pens. These materials range from cotton to Silica, ceramic, stainless steel mesh, and Rayon.
JUUL uses a Silica material as a wick in their JUUL pens.
The wicking in a JUUL is basically like a sort of straw.
The Silica wick draws the liquid from the JUUL pod towards the metal contacts where the liquid is vaporized.
The wick housing holds all of these together in one place, so everything goes smoothly.
#5 Metal Contacts
The metal contacts are gold plated, and they aid with heating the JUUL e-liquid.
The e-liquid is sucked from the tank and is vaporized by the coil assembly.
The coil assembly is connected to the battery via these metal contacts.
#6 Wick and Coil Assembly
The Wick and the Coil Assembly holds the two most critical components of the JUUL, the wick and the coil.
The wick acts like a straw, absorbing e-liquid from the tank and bringing it towards the coil to be heated and vaporized.
The coil is connected to the battery via metal contacts.
The coil is what heats the e-liquid and turns it into vapor.
#7 Tank/JUUL Pod
JUUL likes to call their tank the JUUL Pod.
This is where all the e-liquid is stored.
It is important to note that JUUL is designed to be single-use, meaning once the liquid runs out in the JUUL Pod, you can dispose of it.
But that hasn’t stopped people from refilling the JUUL Pod to keep on using the same pen.
Even though JUUL designed their pen to be a totally closed environment, it is surprisingly simple to refill a JUUL Pod if the need arises.
The battery is probably the largest part inside of a JUUL.
It is shaped like a long and thin USB.
The outside of the battery is made of heat-resistant aluminum to protect it.
The battery housing holds the lithium-ion battery, the control panel, and the pressure sensor.
At the bottom of the JUUL are magnets that help the battery rest in one place for the charging port.
This is to allow the JUUL to be easily recharged via the small USB plug.
According to JUUL, this battery can be stored in temperatures ranging from 41°F (5°C) to 113°F (45°C).
The battery is connected to the two steel prongs at the top of the device that actually do the heating of the JUUL Pod.
The control panel and the pressure sensor are above the battery as well.
#9 Pressure Sensor
When the user inhales via the JUUL mouthpiece, the pressure sensor notices a change in pressure.
This activates the control panel, which in turn instructs the battery to send electricity via the metal prongs towards the coil.
These two metal prongs are connected to the gold-plated contacts that are at the bottom of the pod.
As the battery heats, the contacts, the coil, and the wick transfer this heat to the e-liquid.
The e-liquid turns into vapor and rises up the Airpath or the chimney towards the user.
The liquid is usually heated to about 200°F or 100°C.
The inhaler then pulls the vapor through the chimney towards him by deeply inhaling.
#10 Cap (Bottom)
The bottom cap secures all the components, such as the battery, the pressure sensors, and the control panel, in place.
It also has a magnetized bottom to keep the battery in one place so that the JUUL can easily be recharged.
