The head generates two distinct pulses of the laser beam at the first and second points.

The present disclosure relates to a control method of an aerosol generating device. The control method includes the following steps. In step S100, the aerosol generating device is powered on. In step S200, the aerosol generating device displays a plurality of preset smoking modes and an option of establishing a new smoking mode. In step S300, when a user selects a preset smoking mode, step S400 is executed. In step S400, when the user chooses to execute the preset smoking mode, step S520 is executed. In step S520, the aerosol generating device works in the smoking mode when the user inhales.

An electronic cigarette and temperature control method thereof are provided. The temperature control method of the electronic cigarette includes: identifying type of tobacco liquid in the electronic cigarette; acquiring preset temperature information corresponding to the type of the tobacco liquid; and controlling the electronic cigarette to work according to the acquired preset temperature information. The method of the present disclosure could adjust the temperature of the electronic cigarette automatically to meet user's need, which could simplify operation and improve the user experience.

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices may include an atomizer, a reservoir configured to contain an aerosol precursor composition and an electrical circuit coupled to the atomizer. The electrical circuit may include an electrical generator assembly including a moveable input member and an electrical generator configured to produce an electrical current from movement of the moveable input member. The electrical circuit may be configured to direct the electrical current to the atomizer to produce an aerosol from the aerosol precursor composition. A related aerosol production method is also provided.

The present disclosure relates to an aerosol generating device for heating solid tobacco substance. The aerosol generating device includes a housing having a first air inlet, a power supply, a cup body arranged in the housing, a coil module, and a heating element. The power supply is configured for supplying an alternating current power supply. The cup body is configured for receiving the solid tobacco substance, and defines a second air inlet. The coil module is arranged between the housing and the cup body. Two opposite ends of the coil module are connected to the alternating current power supply, such that the coil module generates a high frequency alternating magnetic field. The heating element is arranged at a center of the cup body. The heating element is configured for generating an eddy current and heat in response to the alternating magnetic field, thus heating the solid tobacco substance.

An e-vapor apparatus may include a pod assembly including a pre-vapor formulation compartment, a first electrical connector, a vapor channel traversing the pre-vapor formulation compartment, and a vaporizer, the pre-vapor formulation compartment configured to hold a pre-vapor formulation therein and in fluidic communication with the vaporizer during an operation of the e-vapor apparatus, the first electrical connector including first and second power electrodes, the first power electrode including a first contact portion on an exterior of the first electrical connector and a first extended portion configured to contact an anode portion of the vaporizer, the second power electrode including a second contact portion on the exterior of the first electrical connector and a second extended portion configured to contact a cathode portion of the vaporizer. The e-vapor apparatus may further include a dispensing body including a second electrical connector configured to connect to the first electrical connector.

A vaporizer assembly includes a tube having a first end with an inlet opening and a second end with an outlet opening. The vaporizer assembly also includes a heater element configured to vaporize liquid aerosol-forming substrate. The heater element is at the second end of the tube. The first end of the tube is fluidly connectable with a liquid storage portion. When the first end of the tube is fluidly connected with the liquid storage portion, the liquid aerosol-forming substrate can flow from the liquid storage portion through the inlet opening into the tube. The outlet opening of the tube includes perforations having a width ranging from about 1 micrometer to about 500 micrometers.
