Definitions

• the disclosure relates generally to a system, device, and method for using a water pipe for smoking.
• Existing and traditional water pipes generally include a plate for supporting charcoal, a head for containing tobacco, a body including an internal pipe, a base for containing water, and a hose.
• a user will first fill the base with water and then place the internal pipe into the water such that the body creates an airtight seal with the base.
• the head is then filled with tobacco, or other organic material, and placed over the internal pipe such that an airtight seal is created between the internal pipe and the head.
• the user places the plate over the head, places one or more lit charcoals on the plate and these charcoals serve to heat the tobacco, or other organic material, underneath the plate.
• the hose is typically attached to the body such that it has an airtight connection with air above the water in the base.
• the user can inhale through the hose, which draws smoke from the heated tobacco, or other organic material, in the head through the internal pipe, through the water contained in the base, through the hose and into the user’s lungs.
• U.S. Patent Publ. No. 2013/0330680 shows an example of a common water pipe and is incorporated by reference herein in its entirety.
• An embodiment of the present disclosure provides a water pipe system including: an inner vessel defining a liquid chamber; a smoke supplying assembly configured to supply smoke to the liquid chamber; an outer vessel in which the inner vessel is disposed, the outer vessel and the inner vessel defining a smoke chamber therebetween, the smoke chamber communicating with the liquid chamber such that smoke drawn from the smoke supplying assembly flows from the liquid chamber to the smoke chamber; and a gasket disposed between the outer vessel and the inner vessel.
• Another embodiment of the present disclosure provides a method including: preparing a water pipe system including: an inner vessel defining a liquid chamber; a smoke supplying assembly configured to supply smoke to the liquid chamber; an outer vessel in which the inner vessel is disposed, the outer vessel and the inner vessel defining a smoke chamber therebetween, the smoke chamber communicating with the liquid chamber; and a gasket disposed between the outer vessel and the inner vessel, drawing the smoke in the smoke chamber to create a negative pressure in the smoke chamber relative to a pressure in the liquid chamber; flowing, by the negative pressure in the smoke chamber, smoke in the liquid chamber from the liquid chamber to the smoke chamber; and drawing smoke from the smoke supplying assembly to the liquid chamber.

Downstem 1324 can terminate in a bowl 1330 at its proximal end with one or more chambers for holding shisha 1328 or other organic material for smoking. Charcoal 1332 can be placed above shisha 1328 in order to heat it and can be covered by a cap 1334 in use, such that airflow can be regulated effectively.
• FIG. IB shows an example embodiment of a side cross-sectional diagram view of a domed water pipe 1302 with supporting tray 1304 including an intake airflow cycle 1300b.

This air can then travel passed shisha 1328, which is being heated by charcoal 1332 within bowl 1330. Airflow continues through downstem 1324 and is initially cleaned in aerator 1322. Once inside liquid chamber 1318, the airflow is further cleansed by liquid contained therein.

• the second one-way valve 5562 may be smaller in minimum operating pressure differential than the one purge valve 5526.
• a user can draw air through a hose attachment 5508. This causes smoke to be drawn from the smoke supplying assembly 5580 into the liquid chamber 5518. Once inside liquid chamber 5518, the flow of the smoke may be cleansed by liquid contained therein. The flow of the smoke may bubble within the liquid chamber 5518 and exits through the inner vessel hole 5512a of inner vessel 5512 into the smoke chamber 5520 between the inner vessel 5512 and the outer vessel 5514 by way of the smoke passages 5551. This allows the smoke to be cooled by both the large surface area of the interior of the outer vessel 5514 and the surface area of the inner vessel 5512, especially when liquid within liquid chamber 5518 is cool. The flow of the smoke then continues through gaps between a manifold 5506 and smoke chamber 5520, through the hose attachment 5508 and a hose and into the user’s lungs for enjoyment.
• the user may draw the smoke in the smoke chamber 5520 to create a negative pressure in the smoke chamber 5520 relative to a pressure in the liquid chamber 5518 (see block 6102).
• the negative pressure may then create a pressure differential between the smoke chamber 5520 and the liquid chamber 5518 sufficient to actuate the one-way valves 5561 in the smoke passages.
• the negative pressure in the smoke chamber 5520 may flow the smoke in the liquid chamber 5518 from the liquid chamber 5518 to the smoke chamber 5520, for example, without limitation, via the first one-way valves 5561 in the smoke passages 5551 of the gasket 5550 (see block 6104).
• FIG. 9 shows an example of a purging method in a block diagram.
• the user may blow a purge gas into the smoke chamber 5520 to create a positive pressure relative to a pressure in the liquid chamber 5518 (see block 6202).
• the positive pressure may flow the purge gas from the smoke chamber 5520 to the liquid chamber 5518 via the second one-way valve 5562 (see block 6204). This may improve efficiency of purging the liquid chamber 5518.
• the second one-way valve 5562 may be smaller in minimum operating pressure differential than the purge valve 5526. Therefore, the purge gas may be transmitted from the smoke chamber 5520 to the liquid chamber, instead of being emitted from the smoke chamber 5520 to an outside of the water pipe system 5500 via the purge valve 5526. This may further improve efficiency of purging the liquid chamber 5518. Then, the purge gas in the liquid chamber 5518 may be transmitted from the liquid chamber 5518 to the smoke chamber 5520 via the first one-way valve 5561 (see block 6206). Then, the purge gas in the smoke chamber 5520 may be emitted from the smoke chamber 5520 to the outside of the water pipe system 5500 via the purge valve 5526 (see block 6208).
• the gasket 5550 may reduce the chance of the liquid in the liquid chamber 5518 splashing out to the smoke chamber 5520. Further, the gasket 5550 may reduce the chance of the liquid chamber 5518 being devoid of smoke.
• the gasket 5550 may be used to fix the inner vessel 5512 to the outer vessel 5514 in embodiments in which the inner and outer vessels 5512 and 5514 are separatable.

• the cylindrical portion 5558b may form smoke passages 5551b.
• Each of the smoke passages 5551b may communicate with the gasket hole 5550c, and extending radially outwardly of the gasket hole 5550c.
• the inner and outer vessels in FIGs. 2, 3, and 10 are illustrated as nested domes, but inner and outer vessels may similarly be nested cylinders separated by a gasket with valves, in view of portability of a water pipe system.
• the gasket 5550 may be made of a flexible material, such as silicone, to ensure a seal between the gasket and the various components of the assembly.
