Abstract: The present disclosure relates to electronic cigarettes having vaporizer assembly with “U” shaped air path and methods of using the same. The electronic cigarette includes: mouthpiece assembly, electronic cigarette body, E-liquid storage tank having a negative air pressure cavity and a number of airflow channels forming “U” shaped air path, and the vaporizer assembly. The vaporizer assembly includes: one or more cylindrical E-liquid storage media, and one or more heating elements. The elements are electrically connected to an electrical power supply through negative air pressure activated switch. When a user sucks air from mouthpiece assembly, a negative air pressure is created in the negative air pressure cavity, the negative air pressure activated switch turns on the electrical power supply to the heating elements, and the heating elements vaporize the E-liquid stored in cylindrical E-liquid storage media to generate electronic cigarette vapor for the user through the “U” shaped air path.

Abstract: Certain aspects of present invention relate to a ceramic vaporizer for e-cigarette and e-cigarettes having ceramic vaporizer with replaceable e-liquid storage medium. In certain embodiments, ceramic vaporizer may include cylindrical vaporizer body, vaporizer heater, and replaceable e-liquid storage medium. Cylindrical vaporizer body has an interior surface, and an exterior surface. Interior surface forms a central vapor passage and exterior surface forms an inside wall of an e-liquid storage device. The vaporizer heater is embedded inside the cylindrical vaporizer body. The vaporizer heater may include one or more heating elements configured to heat e-liquid stored in e-liquid storage device and e-liquid is in direct contact with exterior surface of the cylindrical vaporizer body. The one or more heating elements may include certain electrothermal alloys. In certain embodiments, the one or more heating elements may include one or more mesh heating elements, and one or more spiral heating elements.

Abstract: Aspects of the present disclosure relate to electromagnetic vaporizer assembly, electronic cigarette having electromagnetic vaporizer assembly, and methods of using the same. In certain embodiments, electromagnetic vaporizer assembly includes: an electromagnetic vaporizer, and an electromagnetic heating controller. Electromagnetic vaporizer includes an electromagnetic heating coil to heat a cigarette. Electromagnetic heating controller allows a user to control and use an electronic cigarette having electromagnetic vaporizer assembly. When user inserts the cigarette into a cigarette holder, and presses a push button, the electromagnetic heating controller provides a predetermined AC voltage to the electromagnetic heating coil to heat up the cigarette, and the user enjoys vaporized cigarette.

Abstract: Present disclosure relates to ceramic heating elements and dual-use electronic cigarettes having the ceramic heating elements. In certain embodiments, the dual-use electronic cigarette includes: a mouthpiece and a dual-use vaporizer assembly having a vaporizer upper body connected to a mouthpiece, a vaporizer middle body connected to the vaporizer upper body through a vaporizer connector, a vaporizer power connector assembly connected to the vaporizer middle body, and a heater. The heater includes a bottom heater for vaporizing tobacco wax and a perimeter heater for heating tobacco leaf. When a user places a predetermined amount of tobacco wax in the bottom heater or a predetermined amount of tobacco leaf in the perimeter heater, places the corresponding heater into the dual-use vaporizer assembly, and connects an external electrical power supply to the dual-use vaporizer assembly, the user enjoys the vapor from heated tobacco wax or heated tobacco leaf.

Abstract: Present disclosure relates to a one-way airflow valve and electronic cigarettes having the one-way airflow valve. In certain embodiments, the electronic cigarette includes: a mouthpiece assembly, an E-liquid storage tank for storing E-liquid, a vaporizer assembly having a one-way airflow valve, an electric power connector for receiving electric power, and a condensed E-liquid vapor collection slot for collecting condensed E-liquid vapor to be reused. The mouthpiece assembly and vaporizer assembly form an airflow path. When user connects electric power source to the electric power connector, and sucks electronic cigarette through a mouthpiece, air pressure inside electronic cigarette is reduced which creates air pressure difference, such air pressure difference pushes a one-way airflow blocker upwards to open airflow path, and when user stops sucking, one-way airflow blocker returns to a first position under resilient force of the one-way airflow valve spring to close the airflow path.

Abstract: Aspects of the present disclosure relate to a mouth to lung convertible electronic cigarette. In certain embodiments, mouth to lung convertible electronic cigarette includes: a cartridge top portion, a cartridge bottom portion, and a control circuit. The cartridge top portion includes an E-liquid storage tank and a convertible vaporizer. E-liquid vapor volume generated by convertible vaporizer is selectable by a user and selectable E-liquid volume includes a small E-liquid vapor volume generated by a first set of heating element for mouth smoking and a large E-liquid vapor volume generated by a second set of heating element for lung smoking. In certain embodiments, the first set of heating element includes a first heating element. The second set of heating element may include: a second heating element, the first heating element and the second heating element connected in serial, and the first heating element and the second heating element connected in parallel.
