Water Pipe With Interchangeable Percolator Inserts
A water pipe can include a bottom plate with upwardly extending first and second side walls, a back wall and a removable front wall. When assembled, the bottom plate and walls form a reservoir for containing a volume of liquid. The side and back walls have channels formed in their interior surfaces for installation of porous inserts effecting filtration of vapor drawn through the inserts. The distal end of a vapor introducing tube extends through a side wall into the reservoir, while a proximal end of the vapor introducing tube extends into the exterior environment. A top plate seals an interior volume formed by the bottom plate and the walls extending upwardly therefrom. The top plate has an upwardly extending mouthpiece. Upon introduction of a source of inhalable vapor at the proximal end of the vapor introducing tube, a negative pressure is drawn from the mouthpiece to induce the vapor to travel through the reservoir and through the porous inserts. Removal of the front wall of the water pipe exposes the interior surfaces of the first side wall, the second side wall and the back wall, whereby deposits on the interior surfaces can be readily accessed and removed.
This application claims priority benefits from U.S. application Ser. No. 62/544,042 filed on Aug. 11, 2017 entitled, “Water Pipe With Interchangeable Percolator Inserts”. The '042 provisional application is hereby incorporated by reference herein in its entirety.
FIELD OF THE INVENTIONThe present application relates to water pipes and, in particular, to water pipes having inserts that effect filtration and treatment of smoke drawn through the pipe.
BACKGROUND OF THE INVENTIONSmoking herbaceous material dates back thousands of years. From the ancient Mayans to Native Americans, there have been pipes and countless other devices for inhaling the smoke from the burning herbaceous material. The hookah first emerged in India hundreds of years ago and has been improved upon throughout its history. A hookah is a water pipe originally adapted to smoke opium and hashish, but has since undergone several transformations and is most commonly used more recently to smoke tobacco and cannabis.
A water pipe, of which a hookah a type, is a single or multi-stemmed device for smoking herbaceous materials, such as flavored tobacco, in which the smoke is passed through a water reservoir before inhalation. The user holds a hose with a mouthpiece that constitutes the proximal end of the system. The user places the mouthpiece to his or her mouth and draws on the mouthpiece creating a pressure differential that pulls smoke through the system. The herbaceous material is packed into a bowl with holes formed in the bottom, through which smoke from the burning herbaceous material flows. The smoke passes through the water pipe's stem, into the reservoir, and bubbles through the water in the reservoir, out a port in the reservoir, through a conduit, and ultimately into the smoker's mouth and lungs.
As with any burning herbaceous material, the smoke emerges from the bowl at high temperatures. Smoking implements such as cigars and cigarettes are dried and rolled in leaves or paper with no provisions for cooling the smoke as it enters the user's mouth and lungs, thus producing discomfort to many smokers. The water in the reservoir of a water pipe, on the other hand, serves a primary purpose to cool the smoke and a secondary purpose to filter and purify the smoke.
The water in the reservoir of a water pipe cools the smoke that passes through it while limiting the amount of ash and soot that passes into the user's mouth and lungs.
Existing water pipe designs incorporate in-line mechanisms for filtering the smoke bubbled through the water in the reservoir. In Saliman US2014/0230832A1, an inline filter provides filtration and additional smoke cooling prior to the smoke exiting the system. In Patel US2011/0186064A1, a multistage filtration mechanism employs a conical mouthpiece with external threading by which a first tubular filter housing is connected via internal threading on its top end and is connected via internal threading on its bottom end to external threading on a second tubular filter housing. Filter support discs supporting filter media are crimped into place when the components are screwed into each other, thereby preventing smoke from bypassing the filter medium when inhaling. In Mahoney U.S. Pat. No. 6,067,993, a filter adapter has a number of cylindrical tubes with liquid for washing and cooling smoke. The adapter employs a replaceable filter cartridge containing a filter media.
SUMMARY OF THE INVENTIONShortcomings of existing water pipes are overcome by a water pipe comprising:
(a) a substantially rectangular bottom plate having a first side wall extending upwardly from a side perimeter of the bottom plate and a second side wall extending upwardly from an opposite side perimeter of the bottom plate, each of the side walls having formed in its interior surface at least one side wall channel;
(b) a removable front wall extending upwardly from the front perimeter of the bottom plate;
(c) a back wall extending upwardly from the back perimeter of the bottom plate, wherein the front wall, back wall, first side wall and second side wall, when assembled, form a reservoir for containing a volume of liquid, the back wall having formed in its interior surface at least one back wall channel;
(d) a vapor introducing tube extending through one of the first and second side walls, the vapor introducing tube having a distal end extending into the reservoir and a proximal end extending into the environment exterior to the water pipe;
(e) a substantially rectangular top plate for sealing an interior volume formed by the bottom plate, front wall, back wall, and first and second side walls, the top plate having an opening formed therein, the opening having a mouthpiece extending upwardly therefrom; and
(f) at least one porous insert configured for installation in the first and second side wall channels and the back wall channel, the porous insert effecting filtration of vapor drawn through the porous insert.
In operation, upon introduction of an inhalable vapor at the proximal end of the vapor introducing tube, drawing a negative pressure from the mouthpiece induces the vapor to travel through the reservoir and through the at least one porous insert.
In some embodiments, the at least one porous insert comprises a pair of clamshell members, which, when assembled, are capable of containing a quantity of liquid and effecting filtration of the vapor drawn through the assembled clamshell members. The at least one porous insert can be rendered porous by openings arranged in a honeycomb pattern.
In some embodiments, the at least one porous insert comprises a layer of filtration material.
In at least some embodiments, each of the side walls has formed in its interior surface a pair of side wall channels and the back wall has formed in its interior surface a pair of back wall channels, such that the at least one porous insert comprises a pair of porous inserts insertable in the side wall and back wall channels.
In some embodiments of the water pipe, a sealing gasket is interposed between the front wall and the side perimeters of the first and second side walls.
In at least some embodiments, the water pipe further comprises a sealing gasket interposed between the top plate and the top perimeters of the front wall, back wall and first and second side walls.
In some embodiments, the side walls have fittings disposed therein for receiving fasteners extending through openings in the front wall, such that the fasteners are capable of attaching the front wall to the perimeters of the first and second side walls to form a seal between the front wall and the first and second side walls.
In at least some embodiments, removal of the front wall exposes the interior surfaces of the first side wall, the second side wall and the back wall, such that deposits on the interior surfaces can be readily accessed and removed. As used herein, the term “deposits” is meant to describe the residual material that accumulates on the interior surfaces of a water pipe, for example, particulates and oils, that is removable, either by hand or by a dishwasher.
In some embodiments, in which the back wall is removeable, removal of the front wall and the back wall exposes the interior surfaces of the first side wall and the second side wall, such that deposits on the interior surfaces can be readily accessed and removed.
