Heat Not Burn Vaporizer Devices

Abstract

Vaporizer devices for generating an inhalable aerosol are provided. In one exemplary implementation, a vaporizer device includes a cartridge and a device body having a receptacle configured to receive the cartridge. The cartridge includes vaporizable material, heater chamber(s), heating element(s), inlet(s), airflow outlet channel(s), and airflow outlet(s). The heating element(s) are configured to heat the vaporizable material to generate a vapor, and the inlet(s) are configured to allow external air to enter the heater chamber(s) and entrain the vapor. The airflow outlet channel(s) are in fluid communication with the heater chamber(s), and include at least one condensation chamber configured to condense the entrained vapor with ambient air to form at least a portion of the inhalable aerosol. The airflow outlet(s) are configured to deliver the inhalable aerosol to a user, and in fluid communication with the at least one condensation chamber.
