2. DETAILED DESCRIPTION OF THE INVENTION
[0001] With the objective of eliminating the noxious substances such as tar and nicotine
in cigarette smoke, various cigarette holders or filters have heretofore been designed.
However, in all of them, the elimination of noxious substances is mostly ineffectual
and practically minimal at the most.
[0002] In this respect, it is the object of this invention to provide a smoke purifier which
affords exceptionally efficient eliminative results.
[0003] In its basic form as illustrated in Addendum 1, Figure 1, to the fore of the mouthpiece
(1) there is provided a metallic cooling-chamber tube (3) approximately 30-50 millimeters
in length and with an inside diameter of approximately 10-20 millimeters, with outer
cooling fins (2). The front end of the cooling-chamber piece is provided with a socket
for a cigarette thus making the assemblage a cigarette holder whereby, as shown in
Figure 2, a cigarette (6) is inserted and smoked; or, as shown in Figure 3, a bowl
(8) with a combustion chamber (7) is attached and the assemblage used as a tobacco
pipe.
[0004] As to its usage, referring to Figure to identify each part, the mouthpiece (1) is
detached and the cooling tube (3) is filled with 1-2 sheets of Kleenex-type tissue
paper or a like volume of some such fibrous material (4). The mouthpiece is then reattached.
When a cigarette is inserted and smoked, the smoke flows through the flue (9), enters
the cooling tube (3) wherein it is cooled by adiabatic expansion while, with the effect
of the cooling fins (2) on the exterior surface of the cooling tube, exterior cooling
is also attained. Consequently, noxious substances, such as tar and nicotine, present
in the smoke in gaseous or atomized form, condense and adhere to the fibrous material
(4) in the cooling chamber. It was found that the smoke which then emerges from the
mouthpiece is extremely cleanly purified.
[0005] With respect to this purifying action, a point of special note is that the noxious
substances in the smoke are not just filtered by the fibrous material but that the
smoke which passes through the flue (9) is adiabatically expanded in the cooling chamber
whose diameter is larger and pressure lower than that of the flue section. Concurrently,
by means of the cooling fins (2), the smoke is cooled from the outside. These reactions
convert gaseous noxious substances contained in the smoke to fine liquid particles
which join with those noxious substances in atomized form initially ¡present in the
smoke. Because the fibrous material is placed at the point of this cooling process,
an exceedingly effective condensation and trapping of noxious substances occurs.
[0006] As proof of this, when the fibrous material (4) used in this device is taken out
and examined after several cigarettes have been smoked through it, the material is,
of course, colored a dark brown but a large amount of volatile noxious substances
is trapped in the material and the odor given off is extremely foul. In contrast to
this, when cigarettes are smoked without any device or with hitherto available cigarette
holders or filters, this foul-smelling noxious substance is not at all trapped but
is sucked in directly by the mouth and congeals on or is absorbed by the lungs, windpipe,
lips, palate, tongue, and saliva; with horribly harmful consequences to physical health.
[0007] Incidentally, in applying this invention to a cigarette holder, as shown in Figure
2, the fins (2) may be omitted and a plain metal tube may be utilized, whilst it is
also possible to manufacture it with synthetic materials. However, although such measures
might reduce the manufacturing costs, concurrent reduction of condensation and elimination
cannot be avoided.
[0008] In the foregoing respect, the conditions are identical in the case where, as shown
in Figure 3, the usage is for a tobacco pipe.
[0009] Furthermore, because the fibrous material, such as tissue paper, which is used in
the cooling tube (3) can be any such material readily available and easily replaceable,
the cost of replenishment is close to nil. It is also a great advantage that the inconvenience
and waste due to frequent and inevitable purchases of replacement cartridges for heretofore
available holders and filters become quite needless.
[0010] As set forth, by means of an extremely simple method, a highly effective device for
the purification of tobacco smoke can be provided, and, as a consequence of which,
an immense effect can be made on hygiene.

[0011]
Figure 1 is a cross-sectional plan view of a smoke purification device per this invention.
Figure 2 is a plan view of an application of this invention in a cigarette holder.
Figure 3 is a partially cross-sectional plan view of an application of this invention
in a tobacco pipe.
A device to purify smoke, comprising the special features, to the front of the mouthpiece,
of a cooling chamber with an inside diameter of approximately 12 millimeters and with
a capacity for lightly accommodating fibrous material equivalent to about 1 - 2 sheets
of Kleenex-type tissue paper; of a socket at the front end of the cooling chamber
to accommodate a cigarette; and, to be used as a cigarette holder or, with a tobacco-burning
bowl attached, to be used as a tobacco pipe; the afore-mentioned fibrous material
to be changeable when soiled.
