EP1604578A1 - Narghile with simplified ignition - Google Patents

Abstract

The nargileh has a supporting structure (3) with a base (30) for maintaining a phial (1), a combustible gas container (4) and a heat generator (5) in a relatively stable position, and a cap (32) mounted movable in rotation with respect to base. The generator is placed above a bowl (21) to maintain a combustible mixture of the bowl at an adequate heating temperature. The cap has openings on 36 percent of its surface.

Description

The invention relates, in general, to an article for smoker.

More specifically, the invention relates to a narghile, or water pipe, comprising a filtering flask provided with a suction outlet, a furnace designed to receive a smoking fuel mixture, and a dip tube connecting the furnace inside the flask and diving into operation in water contained in the bottle and intended to filter the descending smoke.

Articles of this type are known and used in Africa and Asia for centuries.

The filtering of the smoke by the water contained in the bottle, the low tobacco content of the mixture fuel, and the relatively low temperature of adequate heating or "distillation" of this mixture, give the narghile considerable advantages for substitute for tobacco consumption practices more widespread in the world and whose dangers are today well known.

The use of a traditional narghile in a modern environment nevertheless raises some difficulties since it requires the manipulation of a incandescent charcoal of natural or origin origin rapid-ignition chemical, intended to prime and maintain the heating of the mixture.

However, not only does this manipulation lead to risks burns and fire, particularly in the event of a fall in embers as a result of a destabilization of the narghile, but the gases and fumes of burning embers (eg carbon monoxide) can be irritating to the smoker or his entourage.

The invention, which lies in this context, aims to to offer a hookah for simple use and extra free from the previously mentioned disadvantages.

To this end, the nargile of the invention, moreover consistent with the generic definition given in preamble above, is essentially characterized in what it includes, besides the filtering bottle, the furnace, and the plunger tube, a supporting structure, a source of energy, and a heat generator, the carrier structure holding the bottle, the source of energy, and the heat generator in a stable relative position, and the heat generator being placed above the furnace and fed, in functioning, by the power source to carry the combustible mixture at a suitable temperature for the distillation.

The supporting structure advantageously comprises a base, this base being able to delimit an internal volume in which is housed the source of energy, and can have a resting surface on which the bottle.

The energy source is for example constituted by a fuel gas reserve, in which case the generator of heat typically comprises a burner connected to the gas supply via duct, duct and burner possibly being held by two amounts of the supporting structure.

Preferably, the burner comprises a pot, a grate internal metal turned to the pot and a grate external metal facing the furnace, the internal and external grids being separated one of the other by a space inside which forms the flame of the burned gas.

The supporting structure comprises for example a cap in which is housed the burner, and thus protecting the environment from any untimely direct contact with this last.

Moreover, the stability of the nargile of the invention can be optimized by providing that the base and the headdress give, together, a substantially pyramidal to the supporting structure.

To facilitate access to the stove during its mixed loading, the cap can be separated from the support surface of the base by a space in which the bottle and the stove can easily be inserted together.

As a variant, the cap can be mounted movably in rotation or in translation relative to the base.

The base presents, for example, a hole through which at least protrudes from the internal volume of this base, a gas lighter or a control valve gas flow.

Finally, the nargile of the invention also includes, in functioning, a cap closing the bottle, this cap being equipped with the suction outlet and a valve to evacuate the overflow of smoke.

Other features and advantages of the invention will be clear from the description which is below, as an indication and not at all limiting, with reference to the attached drawing whose figure unique is a schematic sectional view of the nargile of the invention.

As previously announced, such a hookah includes traditionally a filtering bottle 1, a furnace 21, and a dip tube 22.

The filtering bottle 1, usually but not necessarily made of glass, is half filled with water and has a suction outlet 10 connected, by means of from a quick coupling, to a long hose flexible ended with a mouthpiece held in the mouth of the smoking, the latter elements not being represented.

In operation, this bottle is closed by a stopper 6 for example carrying the suction outlet 10, crossed by the plunger tube 22, and provided with a valve 7 allowing the smoker to blow into the bottle 1 when he wants to evacuate the overflow of smoke.

The stove 21, which is designed to receive the mixture fuel M to smoke, is extended by the tube diver 22 whose lower end bathes, in in the water contained in bottle 1 and intended to filter the descending smoke.

The narghile according to the invention further comprises a carrier structure 3, a source of energy 4, and a heat generator 5.

The carrier structure 3 serves to maintain the bottle 1, the energy source 4, and the generator of heat 5 in a stable relative position.

In the illustrated embodiment, the structure carrier 3 comprises a base 30, two uprights 31, and a cap 32, the cap being connected to the base by the amounts, and the set conferring on the structure carrier 3 an external form similar to a pyramid truncated low angle at the top.

In addition, the base 30 delimits an internal volume in which is housed the energy source 4, and has a resting surface 300 on which is posed the bottle 1.

As shown in the figure, the suction outlet 10 is preferably downward and arranged between the uprights 31 of the structure 3, this arrangement to prevent any tilting of the bottle 1.

Moreover, the suction outlet 10 is advantageously adapted to receive a system of fast attachment, or equipped with such a system, for enable quick set-up and removal and easy of the hose.

The heat generator 5 is disposed above the furnace 21, in the cap 32, and is powered by operation by the energy source 4 to carry the M fuel mixture at a heating temperature adequate.

In the case, illustrated in the figure, where the source of energy 4 is constituted by a reserve 4 of gas fuel, the heat generator 5 comprises essentially a burner 51 connected by a conduit 40, to the gas reserve 4 through a valve 41 of flow control and expander 42.

This control valve 41, and possibly a gas lighter, for example piezoelectric, are at least partially housed in the internal volume of the pedestal 30 and protrude outside the pedestal through a drilling 301 of the latter, this tap and this lighter able to be operated from outside the pedestal 30.

The duct 40 and the burner 51 are advantageously carried at least in part by the amounts 31 of the supporting structure 3.

The burner 51 comprises a pot 510, a grate internal metal 511 turned towards the pot 510 and a external metal grid 512 facing the furnace 21.

These internal and external metal grids 511 and 512, for example made of steel, are separated one of the other by a space inside which is formed, in operation, the flame of the gas burned in the burner 51.

An adjusting zipper 8 makes it possible to adjust the height of the furnace 21 with respect to the burner 51 and to obtain correlatively a more or less rapid distillation mixture M to smoke.

In the illustrated embodiment, the cap 32 is separated from the bearing surface 300 of the base 30 by a space in which the bottle 1 and the stove 21 can be inserted together, in particular to allow easy reloading of the furnace 21 in M mixture, and the ash dump after use.

Alternatively, the cap 32 could be mounted mobile in rotation or in translation relative to the base 30, in order to adopt a position in which the bottle and the furnace are accessible.

The cap 32 is, in its upper part, pierced with lights 320, on 36% of its surface for example, for allow the correct evacuation of the combustion gases and the heat of the burner, otherwise the excessive residual temperature inside the cap may cause micro-explosions combustion gases not exhausted.
