DETAILED DESCRIPTION
[0052] FIG. 1 shows an external upper perspective view of an
improved shisha head 10 according to the present invention. The
shisha head 10 is hollow and comprises a circular upper bowl
section 11 having a larger diameter and a lower circular tubular
section 12 having a smaller diameter. The upper and lower sections
11 and 12 are connected by a tapered section 13 of the lower
section 12. The upper end of the upper section 11 is substantially
closed by a plate 14 located inside the upper edge of the upper
section 11. A circumferential slot or slots 15 is defined between
the edge of the plate 14 and the inner surface of the upper section
11. These slots 15 allow air to pass into the interior of the
shisha head 10.
[0053] In the illustrated example the upper section 11 has a
diameter of about 8.5 cm and a height of about 2 cm, and the lower
section 12 has a diameter of about 4.5 cm and a height of about 9
cm.
[0054] FIG. 2 shows a lower perspective view of the shisha head 10.
In FIG. 2 some parts are shown as transparent in order to allow the
structure of the shisha head 10 to be readily understood.
[0055] As is shown in FIG. 2, the lower section 12 has a plate 16
substantially closing the lower section 12 towards the lower end
12a of the lower section 12. The plate 16 is located about 2 cm
from the lower edge 12a of the lower section 12, and a outwardly
extending part 12b of an outer surface of the shisha head 10
extends between the plate 16 and the lower edge 12a. A circular
cylindrical wall 17 extends downwardly from the plate 16. The wall
17 is concentric with the lower circular tubular section 12 and has
a diameter of about 2.2 cm. The wall 17 extends downwardly about 2
cm so that a bottom edge 17a of the wall 17 is level with the
bottom edge 12a of the lower section 12. A small hole 18 passes
through the lower plate 16 approximately in the centre of the plate
16. The hole 18 allows air to pass out of the interior of the
shisha head 10.
[0056] The shisha head 10 has dimensions selected so that it can be
placed on top of a typical conventional shisha body in place of the
conventional bowl.
[0057] hen the shisha head 10 is in place on a conventional shisha
body, for example the shisha body 106, an upper edge of the shisha
body 106 will be located between the wall 17 and the outwardly
extending part 12b. A seal may be formed between the upper edge of
the shisha body 106 and the plate 16. In some examples a grommet or
other sealing element may be located on the upper edge of the
shisha body 106, or between the wall 17 and the inner surface of
the lower section 12, to improve the quality of this seal.
[0058] In the illustrated example, when the shisha head 10 is in
place on a conventional shisha body 106, an upper end of the tube
109 will be located inside the wall 17, so that the hole 18 will
form an air passage allowing air to pass from the interior of the
shisha head 10 and down the tube 109. A seal may be formed between
the upper end of the tube 109 and the plate 16. In some examples a
grommet or other sealing element may be located on the upper edge
of the tube 109, or within the wall 17, to improve the quality of
this seal.
[0059] The dimensions of the illustrated example will allow the
shisha head 10 to be used together with many conventional shisha
bodies. In alternative examples different dimensions may be used.
In any specific example the dimensions may be selected to cooperate
with specific designs of shisha bodies.
[0060] perspective views from above and below of the shisha head
10, with parts of the shisha head 10 shown as transparent so that
the interior components of the shisha head 10 are visible. FIG. 6
shows a plan view of the shisha head 10 from below, again with
parts shown as transparent so that the interior components of the
shisha head 10 are visible. FIG. 7 shows a partially exploded view
of the shisha head 10.
[0061] The shisha head 10 contains six vapour generation capsules
20 and three batteries 21, which are arranged to supply power to
the vapour generation capsules 20. Each vapour generation capsule
20 is cylindrical and about 7 cm long. The vapour generation
capsules 20 are oriented substantially vertically within the shisha
head 10 and arranged with one capsule 20 in the centre of the
shisha head, with the other capsules 20 arranged equidistantly in a
circle around this central capsule.
[0062] An inner plate 40 is located inside the lower section 12
extending parallel and spaced apart from the plate 16, so that the
plates 16 and 40 define a mixing chamber 41 between them.
[0063] The lower ends of the vapour generation capsules 20 are
located within cylindrical tubular walls 22 extending upwardly from
the upper, interior, surface of the inner plate 40 in order to
support the capsules 20 and hold them in place. There is an
aperture passing through the inner plate 40 inside each of the
tubular walls 22 to allow air to pass into the mixing chamber 41
from a respective capsule 20.
[0064] The components of the shisha head 10 define a number of air
flow paths through the shisha head. Each air flow path passes
through a slot 15 in the plate 14, through a capsule 20 into the
mixing chamber 41, and through the hole 18. All of the air flow
paths pass through the mixing chamber 41 and the hole 18.
[0065] The vapour generation capsules 20 may be electrically
powered atomizers or clearomizers.
[0066] The batteries 21 are arranged in a battery compartment 23
located on the lower, interior, surface of the plate 14.
[0067] The batteries 21 and the vapour generation capsules 20 are
connected by wiring 24. The wiring 24 is shown schematically in the
attached figures. The wiring 24 connects the batteries 21 to the
capsules 20 so that each capsule 20 is connected to both a positive
and a negative terminal of one of the batteries 21, as shown in
FIG. 9.
[0068] In the illustrated example each battery is electrically
connected to two of the capsules 20 by the wiring 24, and each
capsule 20 is electrically connected to a single battery 21 by the
wiring 24, so that each battery 21 supplies two of the capsules 20
with power. In alternative examples the batteries 21 may be
electrically connected together in parallel and the capsules 20 may
also be electrically connected in parallel.
[0069] As shown in FIGS. 10 and 11, each capsule 20 comprises an
outer hollow tube 26 and an inner hollow tube 27 arranged
concentrically. The space between the inner and outer tubes 26 and
27 contains a layer 28 of cotton threads soaked in an e-liquid. The
e-liquid typically comprises propylene glycol, vegetable glycerine
or polyethylene glycol 400, or a mixture thereof as a base, with
active ingredients dissolved in or mixed with this base. The active
ingredients may comprise nicotine and/or flavourings, as discussed
in more detail below. A plurality of resistance heater wires pass
through the layer 28. In the illustrated example the heater wires
are arranged to form a plurality of coils 29 distributed within the
layer 28, with each coil 29 surrounding a group of cotton
threads.
[0070] An airflow sensor 25 is positioned at the top of each
capsule 20. Each airflow sensor 25 is located adjacent the top of
the outer hollow tube 26 of the respective capsule 20 and is
arranged to detect any flow of air through the capsule 20 and into
the mixing chamber 41. When each airflow sensor 25 detects an air
flow through a respective capsule 20 the airflow sensor 25 switches
on the supply of electrical power from a battery 21 to the
respective capsule 20.
[0071] When electrical power is supplied to the heater wires the
coils 29 heat the cotton threads, producing e-liquid vapour.
[0072] The e-liquid within the capsules 20 which is used to produce
the vapour may comprise a solution of e-liquid which contains
nicotine so that the vapour comprises a mixture of e-liquid with
nicotine vapour. The e-liquid within the capsules 20 may
additionally, or alternatively, comprise one or more vaporisable
flavourings so that the vapour is flavoured.
[0073] In the illustrated example the cotton threads of the layer
28 are soaked in water, with the amount of water contained in the
capsule 20 being sufficient for the intended usage life of the
capsule 20. In other examples the capsules may include a water
reservoir to supply water to the cotton threads to replace the
water which is vapourised.
[0074] In one example of use of the shisha head 10, the shisha head
10 is placed on top of a shisha body 30, as shown in FIG. 12. The
shisha body 30 is a conventional shisha body as shown in FIG. 12,
and the usual bowl used with the shisha body 30 is replaced by the
shisha head 10 of the present invention. The shisha head 10 is
arranged so that the first tube 109 of the shisha body 30 is in
communication with the hole 18 in the bottom of the shisha head
10.
[0075] When a user sucks at the mouthpiece 110, producing a partial
vacuum within the chamber 107, air is pulled from the shisha head
10 and into the first tube 109 along the air flow paths passing
through the capsules 20. This air flow is detected by the airflow
sensors 25, which each switch on the flow of electrical power from
the batteries 21 to a respective one of the capsules 20.
[0076] When supplied with electrical power the capsules 20 generate
vapour, which may also comprise nicotine and/or flavour vapour when
nicotine and/or flavours. The vapour from each of the capsules 20
passes into the mixing chamber 41 where the vapour and airflows
from the different capsules 20 intermingle.
[0077] The vapour generated by the capsules 20 then leaves the
mixing chamber 41 and the shisha head 10, and passes through the
hole 18 in the bottom of the shisha head 10 into the first tube 109
of the shisha body 30. The vapour then bubbles through the water
108 into the air space 112 within the chamber 107. The vapour is
then sucked along the second tube 111 to the mouthpiece 110 and can
be inhaled by the user.
[0078] Accordingly, the shisha head according to the present
invention may allow a user to inhale vapour from the shisha,
providing a similar experience to a conventional shisha without the
potential health risks of inhaling tobacco smoke. Further, the
shisha head according to the present invention may allow a user to
enjoy a similar experience to a conventional shisha without
breaking legal restrictions on smoking.
[0079] In examples where e-liquid and nicotine is in the capsules
the shisha head according to the present invention may also allow a
user to ingest nicotine by inhaling the vapour.
[0080] In examples where there are one or more e liquid flavourings
in the capsules the shisha head according to the present invention
may provide an enhanced user experience.
[0081] In another example of use of the shisha head 20, the shisha
head 20 is placed on top of a shisha body 30, as shown in FIG. 13.
The shisha body 30 is a conventional shisha body, as shown in
previous example.
[0082] In the example of FIG. 13 flavour substances are added to
the water 108 by dissolving a soluble flavour capsule 31 in the
water 108. This flavouring may flavour the water resulting in an
increased flavoured vapour provided to the user.
[0083] In this example the flavouring dissolved in the water in the
shisha body according to the present invention may provide an
enhanced user experience.
[0084] In other examples the flavouring material may be added to
the water 108 in a different manner. For example, the flavouring
material may be added in the form of a soluble tablet or powder, or
a concentrated solution.
[0085] In the illustrated example each vapour generating capsule is
associated with a separate dedicated air flow sensor which controls
the supply of power to that capsule. This arrangement may provide
improved reliability through redundancy because even if one or more
of the air flow sensors fails to operate in response to an air
flow, the remaining air flow sensors will still activate their
respective capsules and generate vapour.
[0086] In alternative examples one or more air flow sensors may be
used to control the supply of power to all of the capsules. These
air flow sensors may not be associated with capsules. In one
alternative example a single air flow sensor may be arranged to
sense air flow through the hole 18 and arranged to control the
supply of power to all of the capsules. In another alternative
embodiment the central capsule may be replaced by a single air flow
sensor arranged to control the supply of power to all of the
remaining capsules.
[0087] In the illustrated examples the shisha head is intended to
only be used for a single shisha session, that is a single
"smoking" session, and then discarded. In other examples the shisha
head may be designed for a longer useable life. In general the
useable active life of the shisha head is determined by the amount
of vapourisable water contained in the vapourizer capsules and the
amount of power in the batteries. In some examples the shisha head
may be designed to be refurbished to allow repeated use.
[0088] In some examples the shisha may further comprise a display
to indicate information regarding usage to the user.
[0089] In some examples the display may indicate the number of
vapourization operations carried out, or the number of
vapourization operations remaining before the shisha is exhausted.
In some examples the display may indicate the remaining charge
level of the battery or batteries.
[0090] In the illustrated examples the shisha contains batteries as
a power source. In other examples other power sources may be
used.
[0091] The numbers of vapourizer capsules and batteries in the
described examples are not essential. Different numbers may be used
in other examples.
[0092] The use of batteries as a power supply is not essential. In
other examples other forms of power supply may be used.
[0093] The description above uses directional terms such as upper,
lower, top, bottom, vertical; and the like. It should be understood
that these directional terms are relative and not absolute, and
only apply when the shisha head is in the illustrated
orientation.
[0094] The dimensions of the illustrated examples are not
essential. Other dimensions may be used in other examples.
[0095] The above description relates to exemplary embodiments of
the invention. The skilled person will be able to envisage
alternatives within the scope of the present invention as set out
in the appended claims.
