A water electrolysis device comprises an ion exchange membrane electrolytic cell. The ion exchange membrane electrolytic cell includes an ion exchange membrane, a cathode chamber, an anode chamber, a hydrogen output tube, and an oxygen output tube. An anode is configured in the anode chamber, and a cathode is configured in the cathode chamber. The ion exchange membrane is configured between the anode chamber and the anode chamber. The hydrogen output tube is coupled to the cathode chamber, and the oxygen output tube is coupled to the anode chamber. When water is electrolyzed by the ion exchange membrane electrolytic cell, oxygen is generated by the anode and then exported through the oxygen output tube, and hydrogen is generated by the cathode and then exported through the hydrogen output tube. The hydrogen and the oxygen are exported from the same side of the ion exchange membrane electrolytic cell.

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, and an aerosol passage are interconnected.

The invention relates to a liquid reservoir/wick portion and to an electronic smoking device comprising a liquid reservoir/wick portion. In order to avoid different liquids undesirably mixing in a wick of the electronic smoking device, the liquid reservoir/wick portion comprises a wick. The wick comprising a liquid receiving side coupled to a liquid storage volume of the liquid reservoir/wick portion, and a liquid supply side coupled to an atomizing element of the electronic smoking device.

An apparatus for an electronic aerosol provision system may include a replaceable cartridge for the electronic aerosol provision system or a fixed component of a re-fillable or disposable electronic aerosol provision system. The apparatus includes a reservoir for a source liquid and a carrier module supported within the reservoir. The carrier module defines an airflow path within the reservoir and includes a heating element supported in the airflow path for generating an aerosol from the source liquid and first and second mounting parts which cooperatively engage to support the heating element. The first and second mounting parts cooperatively engage at an interface which extends in a direction substantially parallel to a direction along which air flows in the airflow path when the apparatus is in normal use. A gap between the first and second mounting parts may provide a capillary channel for drawing source liquid to the heating element from the reservoir heating during use.

A vaporization device includes a housing, a fluid pathway extending through the housing, a heating chamber with a heating element proximate a first housing end, a control circuit and a battery disposed within the housing. The heating chamber is in fluid communication with the fluid pathway. The first chamber end is open and the second chamber end includes a closed end with one or more vents. The heating element is operable to generate heat at a predetermined vaporization temperature. The control circuit has a switch operable to control a flow of current from the battery to the heating element. In use, the predetermined vaporization temperature is sufficient to vaporize phyto material in contact with the heat at the predetermined vaporization temperature to emit a vapor. Inhaling from the second housing end draws mixed vapor and air through the fluid pathway.

An electronic cigarette, including an atomization assembly and a battery assembly. The atomization assembly includes an atomizer and an e-liquid tank. The atomizer includes two or more heating elements. The e-liquid tank includes a plurality of compartments corresponding to the heating elements in number. The two or more heating elements are disposed in the plurality of compartments, respectively.
