  • Patent number: 8534296
    Abstract: This apparatus for the smoking of tobacco and other bulk dried material enables those persons who enjoy smoking to do so in a healthier manner. In the described appliance a water bath cools and filters the smoke before it reaches the mouth and lungs of the smoker. An array of, preferably conical, diffusion screens (210) restricts the size of particulate matter passing through the device from the combustion bowl (180) to the user. By controlling air pressures, valves (240) in series with the diffuser (210) prevent water from flowing into it thereby minimizing the pressure a user must apply to draw smoke through the appliance. This keeps solids from accumulating on or in the diffuser which facilitates cleaning. A static turbine (300) in the throat (110) of the appliance aids additional cooling while reducing the amount of suction that must be applied by a user to clear the main chamber.

  • Patent number: 6345625
    Abstract: Secondary smoke is harmful to passive smokers. A filter sleeve (1) comprises a sleeve (10) with a downstream portion (11) adapted for receiving inhale smoke into an inhalation flow path (13), an upstream portion (12) adapted for inhalation of said inhale smoke and for receiving exhale smoke into an exhalation flow path (14), filter means (15) provided along said exhalation flow path (14), and means (16) for checking reverse flow of ambient air through said exhalation flow path (14). A filter sheath (3) is adapted for overlaying a significant expanse of the sidestream smoke emission areas of a rod of smokable material (7), said filter sheath (3) is sufficiently porous and significantly unimpaired by combustion.

  • Patent number: 6216705
    Abstract: A smoking vessel (10) constructed as a tube (11) and a mouthpiece (12) mounted at its one end, a pervious or permeable member (26) therewithin, and a valve-mechanism or assembly (15) at its other end (14) for introduction of a quantity of smoke to be disposed in the tubes' chamber (18) under pressure. A plug (34) mounted in the mouthpiece (12) closes off the neck (20) of tube (16), and includes bores (36) which abut the thickness (t) forming the neck (20). When mouthpiece (12) is unthreaded from neck (20), plug (34) disengages from the neck (20) and the pressurized smoke flows from chamber (18) through the permeable member 26 and into the mouthpiece (12) through bores (36) in plug (34), and thence inhaled by the smoker. The valve-mechanism or assembly (15) at end (14) of vessel (10) provides for introduction into chamber (18) of a quantity of smoke that is pressurized therein.
