EASY-CARE SMOKING APPARATUS HAVING A DISPOSABLE BOWL LINER
Pipes, hookahs and bongs have long been used to smoke tobacco and other combustible materials. The combustion chamber or bowl is a feature of all smoking apparatus's and is where the chosen material to be smoked is inserted. The combustion chamber or bowl is a permanent feature which necessitates cleaning the bowl from time to time to remove burned debris and tar. The present invention introduces a disposable combustion chamber or bowl liner which includes means to enhance tar condensation and collection in a disposable member to simplify cleaning of the chosen smoking apparatus after use and a pipe of the preferred embodiment to be used in combination with the disposable liner is also disclosed.
The present invention relates to a smoking apparatus with a disposable combustion chamber. Particularly, the disposable combustion chamber may include a disposable bowl liner that works with any pipe, hookah, bong or other smoking apparatus having a bowl to hold the combustible materials during combustion.
BACKGROUNDPipe devices for inhaling smoke of burning substances have been made throughout the centuries and in many countries. Some previous known and patented pipe designs have included combustion chamber liners such as Smith in U.S. Pat. No. 4,290,437, Wunshe in U.S. Pat. No. 4,210,160, D R Turner in U.S. Pat. No. 4,190,063, Calkins in U.S. Pat. No. 3,422,821, J L Turner in U.S. Pat. No. 2,419,509, Aldin in U.S. Pat. No. 5,678,573, and Bianchino in U.S. Pat. No. 4,235,252.
For example, Aldin discloses a pipe design with a cylindrical bore open at both ends to allow lighting the tobacco placed therein from the bottom. Aldin also describes desirable attributes of this design such as creating a natural updraft and causing complete combustion without frequent relighting and preventing accumulation of moisture, tar and the like within the pipe bowl. While not referenced by Aldin, Bianchino teaches a pipe design with the identical features (bowl open at both ends) and describes identical components and benefits.
In each of the referenced patents, the combustion chamber liner is a permanent component of the pipe which must be cleaned periodically due to its cost. In some pipe apparatuses, filters are used to remove tar from the smoke stream, but the pipe bowl clean up remains a messy and stinky job, especially when tar gets on fingers or surfaces, being hard to remove. In addition, some art teaches combustion chamber liners that are removeable for cleaning but which are intended to be put back into the pipe and reused. However, none of these prior art teaches or contemplates a disposable combustion chamber or component for providing the smoker an easily cleaned and cost effective smoking device. Moreover, the prior art fails to teach any features or principles that condense and capture tar from inhaled smoke in a component designed for easy disposal, reducing tar reaching the pipe or the smoker.
Thus, there is a need for a low maintenance smoking device having internal components to condense and capture tar from inhaled smoke in a component designed for easy disposal, reducing tar reaching the pipe or the smoker and speeding up and simplify cleaning of the pipe.
SUMMARYThe disposable pipe bowl liner works with any pipe, hookah, bong or other smoking apparatus that has a bowl to hold the combustible materials during combustion. Also claimed is a pipe design of a preferred embodiment that works best in combination with the bowl liner. The disposable bowl liner is inserted into the smoking apparatus's bowl prior to use and after smoking its contents, retains burned materials, tars and other condensed vaporous byproducts for easy disposal. When cleaning is desired, the bowl liner is simply removed and disposed of.
The invention includes structures in the disposable liner that enhance condensation of an undesirable portion of tar and vapor byproducts from the effluent air stream. Such condensation of the vapors is not a filtration process, rather it is a fractionation process.
The instant invention also includes a temperature control element which the user may adjust to modify the tar and byproduct fractions removed from the effluent air stream, allowing for taste preference and in the case of medicinal marijuana, the selection of therapeutic fractions that remain in the effluent air stream.
It is an advantage of the present invention to provide a disposable bowl liner for use with a smoking apparatus having a shank member, a bowl member, a draw tube disposed within the shank member and an air hole disposed at one end of the draw tube for smoking combustible materials and facilitating easy removal of debris and tar after use, including a liner combustion chamber; a smoke collection chamber coupled to a bottom portion of the liner combustion chamber; a liner screen inserted between the liner combustion chamber and the smoke collection chamber; and a liner smoke collection opening disposed along a sidewall of the smoke collection chamber, the liner smoke collection opening may be intimately mated to the smoke draw tube of the smoking apparatus when the disposable bowl liner is inserted into the smoking apparatus.
It is another advantage of the present invention to provide an easy-care smoking apparatus for smoking combustible materials and facilitating easy removal of debris and tar after use having a shank member having an air hole disposed on a first end of the shank member and a smoke draw tube disposed therein; and a bowl member coupled to a second end of the shank member where the bowl member includes an opening formed at a top portion of the bowl member to accept a liner insert, a bowl liner housing for receiving a disposable bowl liner, and a smoke collection opening coupled to the smoke draw tube; the disposable bowl liner may be any removable container structure having a combustion chamber, a smoke collection chamber coupled to a bottom portion of the combustion chamber, a screen inserted between the combustion chamber and the smoke collection chamber, and a liner smoke collection opening disposed along a sidewall of the smoke collection chamber, and the liner smoke collection opening may be intimately mated to the smoke draw tube of the shank member when the disposable bowl liner is inserted into the bowl member.
These and other objects, features and advantages of the present invention will become more apparent in light of the following detailed description of preferred embodiments thereof, as illustrated in the accompanying drawings.
The present invention will be more clearly understood from the following detailed description of the preferred embodiments of the invention and from the attached drawings, in which:
In the appended figures, one or more elements may have the same reference numeral in different figures indicating previously described.
DETAILED DESCRIPTIONA basic structure of a typical and conventional pipe device 100 is provided in perspective views shown in
Referring again to
Smoke byproducts removal may be further increased by the addition of the cooling element and metal ring 401 to the space beneath the liner screen 202F, such as the Peltier cooling element which may be controlled to establish a desired temperature of the smoke chamber and surface enhancing design elements located beneath the liner screen 202F. By controlling the temperature of the disposable bowl liner 202 and the surface enhancing structure 301 beneath the liner screen 202F, an undesired fraction of byproducts may be collected out of the air stream being drawn by the user and a desired fraction not condensed and passed to the user. Such temperature control in the effluent air stream allows users to select the desired byproducts fractions passed into the effluent air stream allowing for greater safety (tar removal), flavor experience (byproducts fractions) and medicinal attributes.
In another implementation, the disposable bowl liner 202 may include a pilot hole (or throttle port) 202K disposed underneath the disposable bowl liner 202 for lighting the easy-care smoking apparatus from the bottom end and mixing of air into the smoke collection chamber 503A.
In summary, the easy-care smoking apparatus described herein includes a novel disposable bowl liner for use with conventional pipes, hookahs and bongs. It should be apparent that the shape and body of the easy-care smoking apparatus are not relevant to the present invention and may include other shaped bowl members 203 and shank members 201. Note, the disposable combustion chamber, or disposable bowl liner 202 does not require a pipe design that includes a bowl with two open ends. Such a disposable combustion chamber liner may be utilized in either a bowl member with one open end or a bowl with two open ends as described herein above. The preferred embodiment is an easy-care smoking apparatus having the bowl member 203 with the two open ends (204 and 206) for the convenience of pushing the liner out from the bottom opening in the bowl when cleaning is desired.
Some preferred material for fabricating the disposable combustion chamber includes any low cost materials which can withstand combustion temperatures, including for example, molded ceramics and composites, formed metals such as aluminum, brass, copper or steel. Similarly, the liner screen 202F may include materials such as ceramic or metal such as aluminum, brass, copper or steel. When the liner screen 202F is placed into the disposable bowl liner 202, a space or chamber is created beneath the liner screen 202F where smoke collects before being drawn out through the smoke draw tube 211 to the user. The bottom of this smoke collection chamber is away from the combustion heat source and burning materials and is cooler than the smoke vapor being drawn through the pipe which causes condensation of some of the smoke byproducts, such as tar, onto its surface. As such, another aspect of the easy-care smoking apparatus is for the disposable combustion chamber to remove a portion of the undesirable tars from the effluent air stream when smoke is drawn through the pipe, without the use of a separate filter. A port for mixing fresh air into the smoke collection chamber may be added to further increase condensation of effluent smoke. To further enhance this desirable attribute of the easy-care smoking apparatus, condensation of tars and other volatile compounds in the combustion chamber beneath the screen, surface enhancing shapes which remove more byproducts of combustion may be added to the smoke collection chamber.
In other embodiments, the disposable liner may facilitate rotational alignment between the side port in the smoke collection chamber and the draw tube. The tab described herein could serve as such an alignment feature.
The disposable combustion chamber may also include a land or step down in diameter for holding a screen in place. The disposable combustion chamber may also include a smoke collection chamber beneath the screen land. The liner below the screen is tapered as shown in
