A recently granted patent (Publication Number: US11766527B2) describes a vaporizer cartridge and device for delivering aerosolized vapor. The vaporizer cartridge includes a cartridge body with a mouthpiece and a reservoir for holding a vaporizable material. The cartridge also features a heating element, a wicking material, and an air tube for delivering the aerosol to the mouthpiece. The cartridge is designed to be magnetically coupled and secured within a cartridge receiver of the vaporizer body. The vaporizer device includes the aforementioned cartridge and a vaporizer body with a cartridge receiver, electrical contacts, and a base. The device also includes a pressure sensor to detect a draw on the mouthpiece and activate the vaporizer, as well as one or more LEDs that illuminate during the generation of the aerosol.

The vaporizer cartridge further includes a bottom cover with air openings and cartridge electrical contacts. It may also have a gasket positioned between the reservoir and the bottom cover. The housing piece that houses the wicking material can be cylindrical.

The vaporizer device, when assembled, allows for the insertion of the vaporizer cartridge into the cartridge receiver, where the electrical contacts on the cartridge and the body make contact. The base of the cartridge receiver is connected to a channel that extends to the pressure sensor, which detects changes in pressure to activate the device. Additionally, the device may include one or more LEDs that illuminate during aerosol generation.

Overall, this patent describes a vaporizer cartridge and device that provide a convenient and efficient way to deliver aerosolized vapor. The magnetic coupling feature ensures secure attachment of the cartridge to the device, while the pressure sensor and LEDs enhance the user experience. The design of the cartridge allows for easy insertion and removal, and the use of ceramic wicking material enhances the vaporization process.
