The present invention discloses an unlocking method for electronic cigarette based on face recognition, comprising the steps of: acquiring user image information, extracting facial feature information in user image information, analyzing the age of the user according to the facial feature information; determining whether the age of the user is within a preset age range; and if the user is within a preset age range, generating an instruction of unlocking an electronic cigarette. The present invention further discloses a face recognition-based electronic cigarette unlocking system, a mobile terminal, a computer readable storage medium, an electronic cigarette and a computer readable storage device. The present invention effectively improves the fun of the control method of the electronic cigarette. At the same time, the inadequacies that the current control method of electronic cigarettes is original and the use of electronic cigarettes cannot be limited for minors are solved.

Disclosed herein are devices and methods for the selective tracing of Cannabis containing vaporizer cartridge through their lifecycle. A permanently a radio frequency identifier (RFID) that is near field communication (NFC) compatible is associated with a vaporizer cartridge having an assigned a unique identifier tag (UIT) and, utilizing a blockchain platform to allow each node in the supply and distribution chain to ledger and in their block of data to the NFC RFID of their transaction.

An atomizer and an electronic cigarette with an atomizer are disclosed. The atomizer includes an atomizer body, in which the atomizer body includes a shell, a suction nozzle assembly mounted at the top of the shell, a liquid chamber and an atomization core disposed in the shell. An electronic cigarette with the atomizer is disclosed as well. The electronic cigarette can prevent liquid accumulation caused by long-time static placement and various misoperations. Furthermore, cigarette liquid does not leak during injection. The components of the atomizer such as the suction nozzle or the base do not need to be disassembled, so that the cigarette liquid is convenient to inject, and the user experience is good.

Disclosed herein are methods and systems to control, limit or stop vapor flow through a vaporizer cartridge and tip. A blocking member such as a twist valve through the tip, a deformable squeeze valve formed as at least a portion of the tip or a plunger formed within a cap having ports which fluidly communicate from the outside of the cap to the inside which is selectively moved in and out of an outlet to limit or prevent vapor flow.

Certain aspects of present invention relate to an electronic cigarette having tamper-proof locking mechanisms. In certain embodiments, the electronic cigarette may include: an electronic cigarette body, a tamper-proof mouthpiece connector locking mechanism threadedly connected to electronic cigarette body, and a tamper-proof power connector locking mechanism threadedly connected to electronic cigarette body. When a user pushes tamper-proof mouthpiece connector locking mechanism towards electronic cigarette body, tamper-proof mouthpiece connector locking mechanism is locked such that the user is able to remove a mouthpiece connector from electronic cigarette body to refill e-liquid for the electronic cigarette. When user pushes tamper-proof power connector locking mechanism towards electronic cigarette body, tamper-proof power connector locking mechanism is locked such that user is able to remove a power connector from electronic cigarette body to replace a vaporizer, a heater for the vaporizer, and e-liquid storage medium of the electronic cigarette.

An atomizer includes a storage member and a cigarette holder. An inductive chamber and an airflow passage are positioned in the storage member. An air suction port is defined on the cigarette holder. The cigarette holder is movably sleeved on an end of the storage member. The cigarette holder can be in a locked state or in an unlocked state with respect to the storage member by moving the cigarette holder. When the cigarette holder is in the locked state, at least one of the inductive chamber and the airflow passage is closed by the cigarette holder. When the cigarette holder is in the unlocked state, the air suction port communicates with both the inductive chamber and the airflow passage.

A smoking article includes a housing that has a mouthpiece and that is configured to receive an aerosol generating substrate. The smoking article also includes a sensor that is positioned at, for example, the mouthpiece and that is configured to detect an oronasal molecule of a prospective smoker of the article. The oronasal molecule can be a molecule that would be expected to be present in breath or saliva of a smoker but not in the breath or saliva of a non-smoker. The sensor is positioned to detect an amount or concentration of a molecule in the smoker's breath or saliva. The smoking article can use data transduced by the sensor to control delivery of an aerosol from the smoking article, such as to prevent delivery of the aerosol.

An aerosol delivery or electronic nicotine delivery systems (ENDS) device may include smoking articles that produce aerosol. The device may operate upon authentication. The authentication may first include an age verification before an authentication allows for operation of the device. The authentication may include a control signal communication to the device. The control signal communication may include an audio signal, such as an authentication tone that is detected by a microphone or pressure sensor on the device. The control signal communication may include a visual, optical, or light signal that is detected by a light sensor or photodiode on the device.

There is provided an aerosol provision device including at least one inlet through which air can enter the device; an outlet through which aerosol within the device can pass; at least one aerosol generating region arranged to generate an aerosol; at least one flow channel arranged to provide fluid communication between at least one inlet, the outlet and at least one aerosol generating region; a moveable component arranged to move between a number of predetermined positions including at least a first and a second position, wherein in the first position the moveable component at least partially blocks at least one flow channel and wherein in the second position the moveable component does not block airflow through at least one flow channel.

A vaporizer apparatus is provided. The vaporizer apparatus includes a cartridge body and a child resistant device. The cartridge body includes an activation button and an inhalation portion. The inhalation portion is operable to allow a user to draw vapor from the cartridge body. The child resistant device includes an outer cap and an inner cap nestled within an inside chamber of the outer cap. The inner cap is coupled with the cartridge body to prevent access to the inhalation of the cartridge body. In a locked configuration, the outer cap and the inner cap are disengaged such that the outer cap is freely movable independent of the inner cap. In an unlocking configuration, the outer cap and the inner cap are engaged with one another such that movement of the outer cap detaches the child resistant device from the cartridge body.
