An attachment device for water percolation filtering of a substance such as a vaporized tobacco or marijuana is provided and a container closure device for use with containers holding a pourable substance. Some embodiments of such devices rely upon a hydrolock aspect which maintains a liquid seal based on adhesive and cohesive properties of the liquids contained therein. It is an aspect of certain embodiments to simultaneously dispense and aerate a fluid stored within a container.

An electronic cigarette includes a cartridge (12) and an atomizing assembly (13); the atomizing assembly (13) is fixed in the cartridge (12); the atomizing assembly (13) comprises a reservoir (105), a liquid guiding medium (106) and a heating element (107); the reservoir (105) has a liquid storage cavity (108) storing tobacco liquid and a liquid outlet (109); the liquid outlet (109) communicates with the liquid storage cavity (108); the liquid guide medium (106) is porous liquid guiding material, and is connected to the liquid outlet (109); the heating element (107) is fixed in the cartridge (12), and a gap exists between the heating element (107) and the liquid guide medium (106); the liquid guide medium (106) guides the tobacco liquid out of the reservoir (105) via the liquid outlet (109) and stores the tobacco liquid; the gap exists between the heating element (107) and the liquid guide medium (106) so that the heating element (107) heats the liquid guide medium (106) without directly contacting the liquid guide medium (106), thus preventing the heating element (107) from polluting the atomized tobacco liquid, and being helpful to the health of a user.

An attachment device for water percolation filtering of a substance such as a vaporized tobacco or marijuana is provided. The attachment device includes an intake chamber, a mouthpiece and a water pipe percolator section. The intake chamber has an opening configured to receive one of a plurality of secondary device mouthpieces or atomizers in sealing engagement, the secondary device mouthpieces or atomizers each belonging to one of a variety of different corresponding design of devices such as vaporizers. The percolator section is in fluid communication with the intake chamber and the mouthpiece and interposed between the two. The percolator is a dome percolator with a cylindrical housing. The intake chamber and the mouthpiece are oriented as in-line extensions of the cylindrical housing.

An automatic cigarette-lighting purifier includes a cigarette holding chamber and a smoke purification device, one end of the cigarette holding is provided with a chamber opening which is communicated with the smoke purification device and the cigarette holding chamber, and a cigarette positioning member is provided at the chamber opening. The automatic cigarette-lighting purifier further includes a ventilation end cap that is movable to cover the end of the cigarette holding chamber that is opposite to the chamber opening, and a cigarette-lighting member is at one side of the ventilation end cap. A cigarette can be lighted automatically by the cigarette-lighting device once it's placed in the purifier, and the burned cigarette is always kept in the purifier, thus no unfiltered second-hand smoke is produced. Furthermore, the structure of the automatic cigarette-lighting purifier is simple, the operation is convenient, and the possibilities of scalding and cigarette ash falling are prevented.

A sheath for a smoking article, such as a filter cigarette, including an exterior sheath (5) that provides a ventilation structure which has a reduced possibility of occlusion, and which also prevents a reduction in filter efficacy when the strength of the draw on the smoking article by the consumer is increased, for example in order to overcome the effects of dilution of the smoke flow with ambient air. The sheath may be manufactured as an independent entity and then fitted to prefabricated smoking articles, or alternatively may be constructed as an integral part of the smoking article.

A smoking article (1) having a mouthpiece (2) for drawing in a particle-loaded gas (3), the particle-loaded gas (3) being heated. To provide a smoking article in which the temperature of the gas, aerosol or humidity absorbed by the user of the smoking article is reduced, the smoking article has at least one cooling element (4) for cooling the particle-loaded gas (3), the particle-loaded gas (3) flowing through the cooling element (4) during the drawing-in action. The cooling element (4) has a cooling material (5), and the cooling element (4) carries out the cooling by an endothermic process of the cooling material (5), the endothermic process being activated by the heated particle-loaded gas.
