Abstract

A pipe comprises a combustion bowl with bowl vents; an inhalation path for drawing smoke from the combustion bowl through the bowl vents during inhalation; an exhalation filter; and an exhalation path for forcing exhaled smoke through the exhalation filter during exhalation.

Claims (28)

1 . A pipe, comprising:

a combustion bowl with bowl vents;

an inhalation path for drawing smoke from the combustion bowl through the bowl vents during inhalation;

an exhalation filter; and

an exhalation path for forcing exhaled smoke through the exhalation filter during exhalation.

2 . The pipe of claim 1 , further comprising a mouthpiece on both the inhalation path and the exhalation path.

3 . The pipe of claim 2 , wherein the inhalation path includes a one-way inhalation valve between the combustion bowl and the mouthpiece.

4 . The pipe of claim 1 , further comprising a lid over the combustion bowl, the lid creating a substantially airtight inhalation seal with the combustion bowl.

5 . The pipe of claim 4 , wherein the lid includes a one-way inhalation valve.

6 . The pipe of claim 2 , further comprising exhalation vents; and wherein the exhalation path includes a one-way exhalation valve between the mouthpiece and the exhalation vents.

7 . The pipe of claim 6 , wherein the one-way exhalation valve is part of the exhalation filter.

8 . The pipe of claim 1 , wherein the exhalation filter includes an exhalation filter cartridge.

9 . The pipe of claim 1 , further comprising an internal lighter for providing a flame to the combustion bowl.

10 . The pipe of claim 9 , further comprising a timed ignition switch for controlling the length of time that a flame is delivered to the combustion bowl.

11 . The pipe of claim 1 , wherein the exhalation filter includes a housing, a HEPA filter, and a foam core.

12 . The pipe of claim 11 , wherein the foam core includes a central bore extending the length of the foam core, and the foam core includes odor absorbing chemicals for removing the odor from the exhaled smoke.

13 . A method, comprising:

burning a combustible substance in a combustion bowl having bowl vents, the burning combustible substance creating smoke;

channeling at least portions of the smoke from the combustion bowl through the bowl vents to a smoker;

receiving exhaled smoke from the smoker;

channeling the exhaled smoke to an exhalation filter; and

filtering the exhaled smoke by the exhalation filter.

14 . The method of claim 13 , wherein the smoke from the combustion bowl is channeled to the smoker via a mouthpiece and the exhaled smoke is received through the same mouthpiece.

15 . The method of claim 14 , further comprising preventing the exhaled smoke from being delivered to the combustion bowl.

16 . The method of claim 14 , further comprising preventing the smoke from the combustion bowl from including air from the exhalation filter.

17 . The method of claim 13 , further comprising controlling the length of time that a flame is delivered to the combustible substance in the combustion bowl.

18 . The method of claim 13 , wherein the exhalation filter includes a housing, a HEPA filter, and a foam core.

19 . The method of claim 18 , wherein the foam core includes a central bore extending the length of the foam core, and the foam core includes odor absorbing chemicals for removing the odor from the exhaled smoke.
