Abstract

An improved water pipe or bong wherein the water that is used to filter and cool the smoke is caused to flush up the inhalation tube, thus pushing the smoke into the smoker'"'"'s lungs. To enhance the flushing effect a water trap is employed to stop the water suddenly and the combustion bowl can be sealed off from the rest of the pipe.

Claims

1. A water pipe or bong comprising an inhalation chamber means, an air intake chamber means;

and a free flow fluid communication chamber means having fluid therein intermediate said inhalation and air intake chamber means;

the fluid within said fluid chamber means having a first surface within said air intake chamber means and a second surface area, within said inhalation chamber means;

a bowl for burning a substance to be smoked;

tubular means for directing smoke from said bowl to the water in said combustion chamber means, said tubular means having an effective cross sectional area considerably smaller then the cross sectional area of said air intake chamber means;

whereby during the first stage by operation of the bong, said air intake chamber means is closed to allow smoke to be drawn from said bowl through said tubular means and said fluid communication chamber means into said inhalation chamber means;

whereby during the second and consummatory stage of the operation of the bong, said inhalation chamber means is filled with smoke and the smoker draws harder and suddenly opens said air intake chamber means while simultaneously inhaling sharply thereby causing an air pressure differential between the two surface areas of the water which causes said water to flush up said inhalation chamber means thus forcing the smoke into the smoker'"'"'s lungs;

water trap means within said inhalation chamber means to prevent the water flushed up said inhalation tube from entering the smoker'"'"'s lungs.

2. The bong as recited in claim 1 including a means for preventing air from entering the bong by way of the bowl;

whereby during the second and consummatory stage of operation the bong can be sealed off from the outside atmosphere thereby permitting maximum possible air pressure differential and maximum ram effect;

said means located on said tubular means

3. The bong as recited in claim 1, wherein said water trap means comprises at least one baffle set having both a funnel, wherein the largest diameter of said funnel is the same as the inner diameter of said inhalation chamber means and an inverted hollow cone located just above said funnel wherein the largest diameter of said cone is slightly smaller than the inner diameter of said inhalation chamber means;

said funnel arranged in said inhalation chamber means with is smallest diameter directed toward said fluid communication chamber means whereby most of said flushing water is splashed downward by the lower surface of the funnel and water that passes through the opening in said smallest diameter end of said funnel is splashed downward by said inverted cone.

4. The bong as recited in claim 1, including a base on said bong of sufficient dimensions to assure said bong'"'"'s free-standing stability.

5. The bong as recited in claim 1, wherein said inhalation chamber means, said air intake chamber means and said fluid communication chamber means are fabricated of different lengths of the same diameter tubing and bonded together to result in a unitary structure.

6. The bong asrecited in claim 5, wherein said inhalation chamber, said fluid communication chamber means and said air intake means made of tubing of differing diameters thereby changing the amount of hydraulic pressure generated in the operation of said bong.

7. The bong as recited in claim 1, wherein said inhalation chamber means, said air intake chamber means and said fluid communication chamber means are fabricated of different lengths of the same diameter tubing and constructed such that the fluid communication chamber is mounted horizontally on said base and said inhalation chamber means and said air intake chamber means are mounted to the two ends of the fluid communication chamber in the perpendicular plane to said base and at angles to the fluid communication tube of between 90°

and 135°

.

8. The bong as recited in claim 7, wherein said tubing is made of a high strength plastic material such as polyvinyl chloride (p.v.c.), polymethyl methacrylate (acrylic) or polycarbonate.

9. The bong as recited in claim 1, wherein said inhalation chamber means, said air intake chamber means and said fluid communication chamber means are fabricated using a single piece of injection molded plastic.
