Multi stage smoke filtration device
Abstract
A filtration apparatus and method used for the inhalation of
smoke that is created from burning substances in a water pipe or
similar, useful for reducing the harshness of smoke, removing
toxins from smoke and flavoring smoke. A two stage filtration
apparatus originates with a mouthpiece adapted to seal off the
opening of the inhalation tube of a typical water pipe. A first
stage tubular filter housing is attached to the bottom end of the
mouthpiece located inside the inhalation tube. A second stage
tubular filter housing is attached to the bottom of the first stage
housing. Smoke passes into the second stage housing and through
circular second stage then first stage disposable filter medium
packets held into place by the filter housings. A method of
pressing the lips against the mouthpiece portion seals off the
inhalation tube opening and frees both of the user's hands so that
one hand can support the water pipe while the other ignites and
reignites the burned substance.

CROSS REFERENCE TO RELATED APPLICATIONS
[0001] Not Applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not Applicable.
BACKGROUND OF THE INVENTION
[0003] 1. Field of the Invention
[0004] The present invention relates to filtration devices for
smoking tobacco or other substances. More specifically, the present
invention relates to mouthpiece filtration devices used with or
near the inhalation tube of a water pipe or similar used to inhale
smoke from a burned substance. More specifically, the present
invention relates to multi stage filtration devices which allow use
of removable filter mediums for smoke filtration.
[0005] 2. Description of Related Art
[0006] There are many devices for filtering inhaled smoke in the
prior art. For example there exists devices that are inserted into
a water pipe such as 4357948 to Schweitzer et al requiring a
special device to insert and remove. Additionally there exist
devices that allow for only one type of filter medium such as
6067993 to Mahoney. Additionally there exist multi stage filtration
mouthpieces such as 3504678 to Pitt and 3327718 to Kilburn which
are designed only for cigarette use and which do not use filter
housings or allow for individual filter replacement. There are
exist multi stage devices for containing smoke but which would not
work with waterpipes such as 5501234 to Hyre.
[0007] There does not exist in the prior art, however, the present
invention which is a multi stage filtration system comprising a
mouthpiece with attached filter housings that allow for individual
filter replacement. This enables replacement of one filter as it
expires without having to dispose of the other filter which may
expire at a different rate. This also allows use of numerous types
of filter mediums for various purposes including cooling the smoke,
toxin removal, and flavoring of the smoke. Some filter mediums
include activated charcoal, dried herbal leaves, rice, cotton, hemp
and cloth.
SUMMARY OF THE INVENTION
[0008] The present invention relates to multi stage filtration
devices used for inhaling smoke from burning tobacco or other
substance in a water pipe or similar. The present invention is
comprised of three in-line components. The first component is 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 preventing smoke from
bypassing the filter medium when inhaling.
[0009] The characteristics and utilities of the present invention
described in this summary and the detailed description below are
not all inclusive. Many additional features and advantages will be
apparent to one of ordinary skill in the art given the following
drawings, specifications and claims.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The present invention may be better understood, and its
numerous features and advantages made apparent to those skilled in
the art by referencing the accompanying drawings. For ease of
understanding and simplicity, common numbering of elements within
the illustrations is employed to identify an element in the
different drawings.
[0011] FIG. 1 is the side view of a water pipe 210 with the
mouthpiece 100, first filter housing 110 and second filter housing
120 fitted into the inhalation tube opening 200 of the water pipe
210.
[0012] FIG. 2 is a perspective view of the separate components of
the filtration system.
DETAILED DESCRIPTION
[0013] Smoke is inhaled by creating a seal with the lips around the
mouthpiece portion 100 positioned at the opposite end of the
inhalation tube portion 200 of a water pipe 210 from the chamber
215 where the smoke from smoked substance is cooled by the water in
the chamber 215. The present invention uses a conical mouthpiece
100 that is inserted into the inhalation tube opening 200 in order
to seal off the tube opening and thereby forcing smoke to go
through the filter housings 120 and 110 and mouthpiece 100. The
largest circumference and smallest circumference and pitch of the
conical portion 108 are of sufficient size to seat the mouthpiece
100 in the opening 200 of most typical inhalation tubes. The three
parts of the in-line device and connected via respective
internal/external threading. The first housing 110, located between
the mouthpiece portion 100 and the second housing 120, contains
internal threading 114 on both ends. At the inner terminus of each
set of threads is a flat protruding ring 118 meant to hold in place
a filter support disc 400. The filter support disc 400 supports a
circular packet 600 containing the filter medium 620 while allowing
air and smoke to pass through a plurality of perforations located
throughout the filter support disc 400. Screwing the top end of the
mouthpiece portion into the first housing crimps the circular
filter packet edge 610 between the bottom of the mouthpiece
threading 104 and the filter support disc 400, thereby preventing
smoke from bypassing the filter medium 620. The same is achieved
with screwing the second housing 120 into the first housing's
opposite end but with a second filter support disc 405 and a second
protruding ring 118. The second filter housing 120 can be of
different lengths as shown in FIG. 1 and FIG. 2 respectively,
depending on the desired cooling effect whereby a longer second
filter housing 120 as shown in FIG. 1 would take in smoke closer to
the water chamber. With both filters installed, a multi-stage
filtration device is configured and is attached to a conical
mouthpiece 100 so that the user is enabled to use the present
device with water pipe inhalation tubes 200 of various diameters to
cool, filter, and/or flavor smoke by forcing the smoke to enter the
second filter housing 120, through its corresponding filter 600 to
the first filter housing 110 and filter 600 and finally through the
mouthpiece 100 where it is inhaled.
[0014] While a conical mouthpiece is the preferred embodiment, a
tubular mouthpiece with a flat disc shaped portion protruding
around the outer circumference of the mouthpiece is also
anticipated, whereby the flat disc portion is utilized to seal off
the top edge of the inhalation tube opening whereby it sits over
and extends past the outer circumference of the top edge and is
pressed against the tube with the lips.
[0015] Additionally, the present invention comprises a method for
sealing off smoke with the mouthpiece portion 100 by using the
user's lips alone. Pushing the mouthpiece 100 against the edge of
the water pipe tube opening 200 with the lips alone frees both
hands while sealing off the opening 200. Existing mouthpieces
require support with one hand in order to be used. The present
invention enables one hand to support the water pipe 210 while the
other hand ignites and reignites the smoked substance 300. It is
necessary to often reignite the substance being smoked in order to
produce sufficient smoke.
