Abstract: A personal vaporizer is configured to be usable both for non-liquid vaporizing media and for liquid vaporizing media. In some embodiments an electrically conductive check valve blocks vaporizing media from leaking out of air intake apertures during periods of nonuse, and delivers electric power to a heating element during use. In some embodiments, no wick structures extend into a fluid chamber, but a wick extends from a wick holder downstream of the fluid chamber to a vaporizing chamber.

Abstract: A cartridge is selectively usable with a personal vaporizer. The cartridge may include a chamber for holding a vaporizing medium such as a liquid solution. The cartridge may also include an atomizer that can be manufactured as a unit with the chamber. The cartridge can be attached to a vaporizer structure such as a battery assembly. A cartridge cover fits over and encloses the cartridge therewithin. The cartridge cover can employ decorative aspects that match or complement decorative aspects of the battery assembly.

Abstract: A vaporizer assembly is shaped and configured to fit partially into a downstem of a water pipe. The vaporizer assembly includes a housing including an upper portion and a lower portion. The lower portion has a smaller diameter, and fits in the downstem. The upper portion of the vaporizer assembly includes a bowl or dish, and a heat source is enclosed within the housing and positioned and configured to selectively heat the bowl or dish. A body of the vaporizer adjacent the bowl includes vapor passages. One or more passages are also formed in the lower portion. Thus, essential oils or waxes placed in the bowl can be vaporized by the heat. The generated vapor may flow from the bowl into and through the vapor passages and lower portion passage and into the waterpipe's downstem.
