AI Technical Summary

Technical Problem

Existing vaporizer devices face inefficiencies in drawing vaporizable material into the vaporization chamber due to vacuum formation in the reservoir, leading to reduced effectiveness and waste of material, particularly when a user puffs on the device.

Method used

A vaporizer cartridge design featuring a wick housing with a heating element and wicking element that draws material from a reservoir, incorporating air inlets and constriction points to maintain pressure balance and prevent leakage, along with a collector for overflow management and condensate recycling.

Benefits of technology

Enhances the efficiency of vaporizer devices by ensuring consistent vaporization of material, reducing waste, and improving airflow control, while minimizing leakage and condensate accumulation.

Abstract

To provide a vaporizer device configured to couple with a vaporizer cartridge.SOLUTION: A cartridge 1320 includes a cartridge housing, a reservoir 1340, a wick housing, a heating element 1350, and a wicking element 1362. The cartridge housing extends below an open top of a receptacle in a vaporizer device when the cartridge is coupled with the vaporizer device. The reservoir contains a vaporizable material. The heating element includes a heating portion disposed at least partially inside the wick housing, and a contact portion disposed at least partially outside the wick housing. The contact portion includes cartridge contacts that form electric coupling with receptacle contacts in the receptacle. The wicking element is disposed within the wick housing proximately to the heating portion of the heating element. The wicking element is configured to draw the vaporizable material to the wick housing for vaporization by the heating element.SELECTED DRAWING: Figure 2A
