  • the vapor may be forced through the narrow neck 127 of the hourglass, limiting the flow of the vapor before it reaches the proximal opening 129 of the lumen 20.
  • the inner surface 114b of the sidewall 114 may be substantially planar or have another shape to affect and/or control the vapor flow.
  • the proximal opening 129 of the lumen 120 may be circular. Or, instead of being circular, it may be any other suitable shape.

  • the exterior groove(s) 233 are formed in the proximal end of the sidewall, and extend from the interior edge 211 in fluid connection with the lumen, to the exterior edge 212 of the sidewall 214.
  • the sidewall extends from a proximal end to a distal end.
  • the sidewall defines a lumen through which vapor may be drawn, the sidewall having an interior edge and an exterior edge.

  • the exterior groove(s) extend from the interior edge, which is in fluid communication with the lumen, to the exterior edge of the sidewall.
  • the groove(s) fluidly connect air outside the mouthpiece with air inside the lumen. As a user draws inwardly on the proximal end of the mouthpiece, they draw vapor from the lumen, and air is also drawn in from outside the mouthpiece, through the exterior groove(s).
  • Mouthpiece 210 as shown includes four longitudinal grooves 233. Instead of four grooves, one groove, two grooves, three grooves, or five or more grooves may be provided.
  • Grooves 233 have a width of about 0.5 mm to about 1.5 mm. In one embodiment, groove 133 have a width of 1 mm.
  • Grooves 233 have a depth of about 0.5 mm to about 1.5 mm, and in one embodiment grooves 233 have a depth less than 1mm. Instead of a width of 1 mm and a depth of less than 1mm, the width and depth could be larger or smaller depending on the desired effects.
  • Grooves 233 have a generally semicircular shape.
  • grooves can have a semi-octagonal shape, or any other shape.
  • Grooves 233 extend from the proximal opening 229 of the inner lumen 120, across a proximal end 225, and down the outer surface 214a of the sidewall 214. Instead of extending to the inner lumen 20 on the proximal end 125, grooves 233 may extend only from the proximal end 225 down the outer surface 214a of the sidewall 214. Grooves 233 may extend down the outer surface 214a of the sidewall 214 partially towards the distal end 218, or fully to the distal end 218.

  • One or more grooves 233 may prevent a user’s mouth from creating a perfect seal across the proximal end 225 when they inhale through the proximal opening 229 of lumen 220.
  • Users are known to place their mouths partially or sideways over a portion of the proximal opening 229 in order to approximate the effect created by the grooves 233. That is, users place a portion of their mouth over a portion of the proximal opening 229 and inhale, thus inhaling some vapor through the portion of their mouth that is over the proximal opening 229 and inhaling some fresh air through the portion of the mouth that is not over the proximal end.

  • the heat sink may be, for example, a cylindrical heat sink in connection with the lumen.
  • the cylindrical heat sink may have a heat sink lumen 349 therethrough, and at least some of the vapor drawn into the mouthpiece lumen 320 may also be drawn through the heat sink lumen 349. As the vapor passes the heat sink lumen 349, it may be cooled.
  • the heat sink is not cylindrical and/or does not include a lumen, such that the vapor may pass by the heat sink rather than through the heat sink.
  • the heat sink 337 is located at the proximal end 325 of the inner wall 314b.

  • Heat sink 337 is circular with a heat sink lumen 349 extending therethrough. Instead of being circular, heat sink 337 could have any other suitable polygonal shape, and may include one or more ridges or cut-aways for customizing its heat sinking properties. In one embodiment the heat sink 337 is octagonal, and in other embodiments the heat sink has different geometries. Likewise, the thickness of the heat sink 337 may be varied and optimized depending on the temperature control desired.
  • the heat sink 337 shown in the embodiments illustrated in FIGs. 5-6 can be combined with any other embodiments shown herein.
  • an embodiment of a mouthpiece 410 may include an interior spiral 442, or vortex, formed within the lumen 420 on the inner wall 414b of the sidewall 414.

  • Mouthpiece 510 includes four grooves 533 formed in the outer wall 514a of the mouthpiece 510.
  • Grooves 533 may be about 1 mm to about 3 mm wide, about 1.5 mm to about 2.5 mm wide, or about 2 mm wide.
  • Groove(s) 533 may typically be less than 1 mm deep. In one embodiment, the grooves are 2 mm wide and less than 1 mm deep.
  • the number of grooves, position of grooves, width of grooves, and depth of grooves may all be varied to achieve desired results with respect to the amount of outside air taken in through the grooves.
  • An interior spiral airpath 542 may be provided. Instead of an interior spiral air path 542, a planar interior wall 514b may be provided.
  • At least one aperture extenda through the sidewall, fluidly connecting the interior lumen to the exterior surface of the sidewall and enabling air from exterior to the mouthpiece to be drawn into the interior lumen 620 through the at least one aperture when a user inhales on a proximal opening of the mouthpiece.
  • mouthpiece 610 may include a circumferential groove 646 formed in the exterior surface of the sidewall.
  • Circumferential groove 646 extends around the circumference of the outer wall 614a. Instead of extending around the entire circumference, groove 646 may be provided at only select portions of the circumference. In some embodiments a groove 646 is not provided and the outer wall 614a may be substantially planar.
  • apertures 650 extend from the outer wall 614a within the groove 646 to the inner wall 614b of the sidewall 614.
  • Apertures 650 connect the lumen 620 defined by the inner wall 614b to the outer wall 614a, and thus make the lumen 620 in fluid connection with fresh air from outside the mouthpiece 610.
  • Apertures 650 are shown as being generally circular. Instead of being circular, apertures could be any suitable polygonal shape. In other embodiments, one, two, three, four, five, six, or more apertures can be used. Similarly, apertures can be varied in size to achieve the desired air cooling effects.
  • Apertures 650 are recessed within the groove 646. By recessing apertures 650 within the groove 646, it reduces the chance of a user inadvertently covering the apertures 650 entirely when a user has their hand on the mouthpiece 610. Because apertures 650 extend to the lumen 620, as a user inhales on the proximal end 625 of the mouthpiece 610 and through the proximal opening 629, air is drawn from the outside of the mouthpiece, through apertures 650 and into the lumen 620. Similarly, vapor is drawn up through the center of the lumen 620 from the cartridge. The air drawn from outside the mouthpiece 610 may mix with the vapor drawn up the lumen and serve to cool the vapor in the lumen 620.
  • Mouthpiece 610 may be provided with an interior spiral as discussed above with reference to FIGs. 7-8, and/or one or more heat sink elements.
  • the mouthpiece can include one or more exterior longitudinal grooves.

  • Apertures 750 connect the groove 733 on the outer wall 714a to the lumen 720 defined by the inner wall 714b.
  • Apertures 750 are recessed within the grooves 733 to prevent a user from inadvertently covering the apertures entirely when a user has their hand on the mouthpiece 710.
  • One aperture 750 is shown in each of grooves 733, but instead of just one aperture in each groove 733, two or more apertures can be used. In other embodiments, some grooves may have no apertures.
  • the grooves 733 extend up from the aperture 750 to the proximal end 725.
  • the grooves 733 extend to the proximal opening 729 of the lumen 720. In other embodiments, the grooves 733 do not extend to the proximal opening 729.

  • Mouthpiece 710 includes an interior spiral 742 formed within the lumen 720 on the inner wall 714b of the sidewall 714 (as described in detail with respect to FIGs. 7-8 above). Instead of an interior spiral 742 in the lumen 720, substantially straight inner walls 714b of the sidewall 714 may be provided.
