An electronic cigarette vaporizer comprises a hollow vaporizer housing and a vaporizing device sleeved inside the vaporizer housing; wherein the vaporizer housing has a mouthpiece end and an opening end arranged with a connecting device for connection with the battery component, a mouthpiece is arranged in a center of the mouthpiece end, a vapor outlet tube extending in an inward direction from the mouthpiece to a middle portion of the vaporizer housing is arranged; wherein the vaporizing device is disposed in the vaporizer housing at one side where the opening end is formed, and comprises a vapor tube sleeve, a throttle lid, a heating unit, a vaporizing base and an electrode lid, which are arranged in turn towards the outer side from the inner side, and the throttle lid is provided with throttle orifices for directly communicating the liquid storage chamber and the end portions of the liquid guiding strip.

A machine for dispensing a vaporisable liquid into a container for use in an electronic inhalation device is disclosed. The machine comprises a reservoir of liquid, a dispensing port to receive an empty container to be filled, and a dispensing mechanism fluidly connected to the reservoir for dispensing a quantity of liquid from the reservoir to a container received in the dispensing port. The machine also comprises a controller connected to the dispensing mechanism to control operation thereof, and a user-operable interface connected to the controller for a user to actuate the machine. Also disclosed is a method of operation of such a machine and a system of a plurality of such machines.

An upper cover assembly includes an upper cover, a liquid filling cap movable relative to the upper cover between a usage position and a liquid filling position, and a mouthpiece. The upper cover is provided with a liquid filling hole and a smoke outlet hole. The liquid filling cap is provided with a through hole. The mouthpiece is integrally formed with the liquid filling cap and is in communication with the through hole. When the liquid filling cap is in the usage position, the liquid filling cap covers the liquid filling hole and the through hole is in communication with the smoke outlet hole. When the liquid filling cap is moved from the usage position to the liquid filling position, the liquid filling cap is displaced from the liquid filling hole and the liquid filling hole is opened.

The ventilation assembly for an atomizer in an electronic cigarette has a storage chamber, which includes an inlet passages and a liquid injection channel located therein. The inlet passages and the liquid injection channel are isolated from each other. The ventilation assembly further includes an injection hole, an air inlet, the injection hole is in communication with the liquid injection channel and the storage chamber sequentially; and an exhaust port, the exhaust port, and the air inlet are in communication with the inlet passages; when need to inject cigarette liquid, open the injection hole and inject the cigarette liquid into the storage chamber through the injection hole; after the liquid injection is completed, during closing the injection hole, air received in the storage chamber is discharged from the injection hole, exhaust port, the air inlet passage and the air inlet successively.

The present invention solves some of the problems of the prior art by providing a method, system and apparatus for readily refilling the reservoir of a smoking-substitute device with liquid from a dispenser. The method, system and apparatus of the present invention prevents liquid from being dispensed until the dispenser is securely and sealably engaged to the smoking-substitute device, provides independent liquid and gas pathways between the dispenser and reservoir, and substantially alleviates the problems of spillage and/or leakage when dispensing liquid from the dispenser into the reservoir of the smoking-substitute device.

An e-liquid filling structure, including a drip tip with an e-liquid cartridge, an air duct provided in the drip tip, a base mounted to the drip tip, an atomizing core on the base, and a connecting seal hermetically connecting the atomizing core to the air duct. Embodiments of the present invention further disclose an assembly and e-liquid injection method of an e-liquid filling structure, including installing an atomizing core, pre-installing a connecting seal, injecting e-liquid, and installing a base. An e-liquid injection hole in the embodiments of the present invention not only allows injection of e-liquid but also functions to fasten the atomizing core while another e-liquid filling hole is spared, so that the atomizing core is reliably sealed.

A reservoir refill system for an electronic vaping device includes a refill container and a reservoir. The refill container contains a pre-vapor formulation. The refill container includes a body, an opening in the body, and a first interlocking ring including at least one groove or at least one protrusion therein. The reservoir is configured to contain a pre-vapor formulation and includes a reservoir body, an opening in the reservoir body, and a second interlocking ring including at least one groove or at least one protrusion therein at an opening of the reservoir. The first interlocking ring is configured to mate with the second interlocking ring so as to release the pre-vapor formulation from the refill container to the reservoir.
