An electronic cigarette vaping device is provided and includes a first element, a heating structure and a second element. A first thread is provided at a connecting end of the first element, a second thread is provided at a connecting end of the second element. The first thread is one of an external thread and an internal thread, the second thread is the other of the external thread and the internal thread. The first thread is threadedly engaged with the second thread. Along the axial direction of the electronic cigarette vaping device, the first element is provided with a sliding groove extending from the connecting end of the first element toward a direction away from the second element. The sliding groove runs through the first thread. The vaping device can not only protect the heating member, but also facilitate the cleaning of the heating member.

A charging device for an electronic cigarette system is provided. The electronic cigarette system includes a smoking device. The smoking device includes a heating member. The charging device includes a housing and a cleaning device located in the housing. The housing is provided with a hollow chamber configured for receiving the smoking device and an accommodation cavity configured for installing the cleaning device. The accommodation cavity is in communication with the hollow chamber. When the smoking device is placed into the hollow chamber, the cleaning device in the accommodation cavity is configured to contact with the heating member of the smoking device and clean the heating member. The charging device is convenient for the user to carry the cleaning device and clean the heating member.

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.

A novel water filtration apparatus is disclosed having a downstem assembly from which a combustion aerosol or an aerosol is generated. The water filtration apparatus including a rotatable water filtration assembly rotatably mounted about a fixed shaft member and including two chambers generally separated by a divider wall having drain passage formed therein and wherein the rotatable water filtration assembly is normally oriented vertically with one chamber being disposed over the other and wherein said chamber is adapted to contain a volume of liquid that moves from one chamber to the other through the drain passage in response to rotating the rotatable water filtration assembly one-half turn. Routing of the aerosol through an upper disposed chamber and percolating the aerosol through the liquid and as the liquid within said chamber moves from the upper oriented chamber to the lower oriented chamber after each half turn, the falling liquid creating a vacuum space above the falling liquid in the upper chamber that draws air through the downstem assembly and the aerosol flowing and percolating into the upper disposed chamber while aerosol contained in the lower chamber is exhausted from said chamber via an exhaust opening towards a mouthpiece assembly.
