  • FIGURE 2C provides a close-up view of the diverter valve 210.
  • the diverter valve 210 is sealed against the mouthpiece 102 so as to prevent any undesirable leakage of emissions from the filter cartridge assembly 114 and/or vaporized material from the cooker chamber 107.
  • the diverter valve 210 includes two one-way valves: an inlet check valve 212 and an outlet check valve 214.
  • the inlet check valve 212 is a one way valve that allows vapors to escape the cooker chamber into the mouthpiece 102 on inhale, but substantially blocks and/or prohibits emissions from entering the cooker chamber from the mouthpiece 102 on exhale.
  • the outlet check valve 214 is a one way valve that allows exhaled emissions to enter from the mouthpiece 102 into the filter cartridge assembly 114, but substantially blocks and/or prohibits emissions from exiting the filter cartridge assembly 114 into the mouthpiece 102 on inhale.
  • the inlet check valve 212 is implemented using a one-way umbrella valve.
  • the pressure differential caused by the inhalation causes a body portion of the umbrella valve to lift away from a base portion, thereby allowing vaporized materials to move from the cooker chamber 107 into and out of the mouthpiece 102.
  • the body portion of the umbrella valve is pushed into the base portion. This causes the body portion to become seated within the base portion and closes the inlet check valve 212, thereby preventing any emissions from entering the cooker chamber 107 from the mouthpiece 102.
  • the outlet check valve 214 is implemented using a duckbill valve.
  • the duckbill valve includes two or more flaps that meet at a point (220).
  • a user inhales on the mouthpiece 102, the flaps are pulled towards one another, thereby closing the outlet check valve 214.
  • inhalation will not cause any emissions to escape from the filter cartridge assembly 114 into the mouthpiece 102.
  • the flaps are pushed apart, creating an opening at the end point 220 and allowing exhaled emissions to flow from the mouthpiece 102 through the outlet check valve 214 into the filter cartridge assembly 114.
  • inlet check valve 212 as an umbrella valve
  • outlet check valve 214 as a duckbill valve
  • both the inlet check valve 212 and the outlet check valve 214 can be implemented using any one-way valve.
  • the inlet check valve 212 is tilted towards the outlet check valve 214. This angling of the inlet check valve 212 allows for any non-gaseous emissions (e.g., spit, resins, etc.) to be pulled towards the outlet check valve 214 and into the filter cartridge assembly 114 by gravitational forces. In certain scenarios, if the inlet check valve 212 is not angled towards the outlet check valve 214, liquids and sticky resins can become trapped within the mouthpiece 102, which can cause undesirable buildup of waste materials within the mouthpiece 102.
  • any non-gaseous emissions e.g., spit, resins, etc.
  • FIGURES 3A-C provide various cross-sectional views of the mouthpiece 102, the inlet check valve 212, and the outlet check valve 214.
  • FIGURE 4 illustrates an exploded view of an example filter cartridge assembly
  • the filter cartridge assembly 400 of FIGURE 4 can be used as the filter cartridge assembly 114 of FIGURE IB.
  • the filter cartridge assembly 400 includes an open-ended tubular, cylindrical main enclosure body 414, which is at least partially enclosed at the top by an inlet cap 402 and at least partially enclosed at the bottom by a vented outlet cap 422. Between the inlet cap 402 and the vented outlet cap 422, and housed within the main enclosure body 414, are various filtering mechanisms that assist in removing odors and particulate matter from emissions blown into the filter cartridge assembly 400. Emissions are received into the filter cartridge assembly 400 via the inlet cap 402. Once the emissions pass through various filtering mechanisms housed within the main enclosure body 414, clean, filtered emissions are emitted via the vented outlet cap 422.
  • the inlet cap 402 can be configured to form an airtight seal with the outlet check valve 214 (see FIGURES 2B, 2C, 3A, 3B, 3C) to ensure that emissions that have entered the filter cartridge assembly 400 do not leak at the inlet cap/outlet check valve juncture.
  • the inlet cap 402 can include threads that can be secured to corresponding threads surrounding the outlet check valve 214.
  • the inlet cap 402 can also include an O-ring 404 to further ensure a tight seal between the inlet cap 402 and the outlet check valve 214.
  • the mesh screen 406 acts as a demister and assists in condensing vapor emissions into condensate.
  • the mesh screen 406, and any other components described herein, can be made from any appropriate materials.
  • the mesh screen 406 can be made of stainless steel or plastic.
  • Below the mesh screen 406 is an air separator inlet 408.
  • the mesh screen 406 can be sized to substantially cover a top opening of the air separator inlet 408.
  • the air separator inlet 408 is an elongated tube that is divided into sections by partition walls that run through substantially the length of the air separator inlet 408. The partition walls are more clearly shown in FIGURE 5C.
  • the partition walls within the air separator inlet 408 divide exhaled emissions into various sections, and provide surface area that encourages further condensation of the emissions.
  • the air separator inlet 408 feeds into a venturi reaction chamber 412.
  • a polyester felt filter 410 Positioned between the air separator inlet 408 and the venturi reaction chamber 412 is a polyester felt filter 410.
  • the polyester felt filter 410 absorbs some portion of the condensate that has already formed, and also filters out some particulate matter in the emissions.
  • the polyester felt filter 410 is a 1 micron polyester felt filter.
  • venturi reaction chamber 412 which is a funnel-shaped tube having a wider mouth portion that narrows into a narrower stem portion. This narrowing causes the emissions to accelerate through the venturi reaction chamber 412. As emissions accelerate through the venturi reaction chamber 412, additional air is pulled into the venturi reaction chamber 412 through openings 413 proximate a top end of the stem of the venturi reaction chamber 412. As will be described in greater detail below, the design of the venturi reaction chamber 412 assists in keeping emissions trapped within the filter cartridge assembly 400 for a longer period of time, thereby increasing the effectiveness with which the emissions can be filtered.
  • the narrower stem portion of the venturi reaction chamber 412 is surrounded by a cylindrical mesh filter 416.
  • the stem portion of the venturi reaction chamber 412 and the cylindrical mesh filter 416 are inserted into a diverter 418.
