US Patent 11998047 Personal vaporizer and method for assembly

A personal vaporizer is constructed so that a tank module is filled with a vaporizing medium prior to being attached to a mouthpiece module. During filling, the tank module is in a first configuration in which a structure blocks media within the tank from flowing into an air path of the tank module. When the mouthpiece module is attached to the tank module after filling, the structure is modified, moving the tank module into a second configuration. However, in the second configuration an elongated tube of the mouthpiece module blocks media within the tank from flowing into the air path of the tank module.
