A device for vaporizing a composition. The device comprises a thermally conductive substrate having a surface, the surface comprising a thermally conductive surface structure. A dry composition capable of a solid to liquid phase change upon being heated to at least a select temperature is disposed on the surface structure. The surface structure is configured to form liquid droplets of the composition upon heating of the surface structure to at least the select temperature. The liquid droplets have a median diameter less than a median diameter of liquid droplets formed on a planar substrate surface heated to at least the select temperature.

Disclosed is an atomizer, comprising an atomizer body, a suction nozzle assembly mounted at the top of the atomizer body, an air inlet provided in the atomizer body, an atomizing sheet and a tobacco tar cavity provided in the atomizer body, and a tobacco tar guide body which guides tobacco tar in the tobacco tar cavity to an atomizing surface of the atomizing sheet. The atomizer introduces entered air to allow all the air to pass over, at a low level, the surface where the atomizing cotton is in contact with the atomizing sheet. The atomizing efficiency is higher, and more smoke is produced.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source to a vaporization port where the vaporization port has lateral dimensions varying from 10 um to 300 um, applying heat to the liquid in the vaporization port with an at least one heating element located in thermal communication to the vaporization port, and releasing vaporized liquid from the vaporization port into the surrounding environment so that fluid is transported through the depth of the structure.

The present invention relates to an electronic atomizing device and a liquid injecting structure thereof. The liquid injecting structure includes an outer tube and a liquid injection assembly in the outer tube. The outer tube defines an inlet port, the liquid injection assembly includes a switch assembly rotatable between an injecting position and a working position relative to the outer tube; the switch assembly includes a liquid injection tube defining an injecting port. When the switch assembly is in the injecting position, the injecting port is fluidly communicated with the inlet port, such that liquid can be injected into a liquid storage cavity; when the switch assembly is in the working position, the injecting port is isolated from the inlet port. The rotation operation is child-resistant; when the switch assembly is in the working position, the liquid injecting structure is shielded by a battery and cannot be opened accidentally.

An aerosol-generating system may include a device body and a cartridge configured to be removably inserted into or connected to the device body. The device body may include a power supply and an electrical heater connected to the power supply. The cartridge contains an aerosol-forming substrate in the form of a thermoreversible gel that is a solid at room temperature.

An electrically operated aerosol-generating system may include a reservoir configured to hold a liquid aerosol-forming substrate, an atomizer assembly configured to vaporize the liquid aerosol-forming substrate to form an aerosol, and a pump configured to convey the liquid aerosol-forming substrate from the reservoir to the atomizer assembly. The reservoir may include a substantially rigid housing and an inlet valve that is configured to allow air into the reservoir based on a pressure difference between an interior of the housing and an exterior of the housing exceeding a threshold pressure difference. This improves the reliability and efficiency of delivery of liquid to the wick. The system may further include a robust reservoir that is configured to at least partially mitigate liquid leakage between the reservoir interior and the reservoir exterior.

An atomizing assembly includes a tubing section having an inlet end and an outlet end. The inlet end of the tubing section is connectable to a liquid storage portion, and the outlet end of the tubing section is in fluid communication with an atomizing nozzle. The tubing section is configured to deliver a flow of liquid aerosol-forming substrate through the atomizing nozzle. The atomizing nozzle includes an air channel configured to establish an air flow through the nozzle. The air flow is mixed with the flow of liquid aerosol-forming substrate.

An atomizer and an electronic cigarette having the same are provided, the atomizer includes a base; an adjusting ring fixed on the base and configured to adjust a volume of air inflow, the adjusting ring bored with a first air inlet; and an atomizing component partly received in the adjusting ring and being in rotatable connection with the base. Part of the atomizing component received in the adjusting ring is bored with a second air inlet corresponding to the first air inlet. When an external force drives the atomizing component excluding the part thereof received in the adjusting ring to rotate relatively to the base, an overlap ratio of the first air inlet and the second air inlet is capable to be adjusted.

The portable insecticide dispenser is an electromechanical device. The portable insecticide dispenser vaporizes an insecticide using a method selected from the group consisting of evaporation and sublimation. The portable insecticide dispenser diffuses the vaporized insecticide into the atmosphere. The portable insecticide dispenser comprises a housing, a control circuit, and an essential oil. The housing contains the control circuit and the essential oil. The essential oil is a lipid-based substance that contains a substance known to be an insecticide. The control circuit vaporizes the essential oil such that the insecticide forms a gas phase that mixes into the atmosphere. The control circuit further mechanically diffuses the gas phase of the insecticide into the atmosphere.
