Recreational inhalation device

Abstract

A recreational inhalation device for a user to inhale smoke and/or vapour. The recreational inhalation device comprises a device body having an inlet for receiving smoke and/or vapour, an outlet for emitting smoke and/or vapour to the user. A passage extends between the inlet and the outlet for conveying smoke and/or vapour from the inlet to the outlet. A plurality of baffles at or adjacent to the passage forms a tortuous pathway between the inlet and outlet.

1 . A recreational inhalation device configured to be used by a user to inhale at least one of smoke and vapour, the recreational inhalation device comprising:
 a device body having an inlet to receive at least one of smoke and vapour, an outlet at least one of smoke and vapour to the user, a passage between the inlet and the outlet to convey at least one of smoke and vapour from the inlet to the outlet, and a plurality of baffles at or adjacent to the passage for forming a tortuous pathway (B) in three mutually perpendicular directions between the inlet and outlet.   
     
     
         2 . The recreational inhalation device as claimed in  claim 1 , wherein said plurality of baffles includes an inlet baffle at or adjacent to the inlet which forms a barrier to direct flow of smoke and/or vapour from the inlet to the outlet. 
     
     
         3 . The recreational inhalation device as claimed in  claim 1 , wherein said plurality of baffles includes a plurality of passage baffles at or adjacent to the passage to disrupt a flow of smoke and vapour through the passage. 
     
     
         4 . The recreational inhalation device as claimed in  claim 3 , wherein each passage baffle is a curvately convex protrusion. 
     
     
         5 . The recreational inhalation device as claimed in  claim 1 , wherein the device body has a plurality of recesses at or adjacent to the passage. 
     
     
         6 . The recreational inhalation device as claimed in  claim 5 , wherein the device body has first and second body portions at or adjacent to opposing sides of the passage, the first body portion having at least one of said plurality of baffles and the second body portion having at least one recess. 
     
     
         7 . The recreational inhalation device as claimed in  claim 6 , wherein the or each baffle of the first body portion is aligned with the or each recess of the second body portion so that said tortuous pathway at least in part extends in a direction towards the first body portion and at least in part extends in a direction towards the second body portion. 
     
     
         8 . The recreational inhalation device as claimed in  claim 7 , wherein a peak distal to the first body portion of the or each at least one baffle of the first body portion extends at least to an opening of the or each recess of the second body portion. 
     
     
         9 . The recreational inhalation device as claimed in  claim 8 , wherein said peak extends to said opening of the or each recess of the second body portion. 
     
     
         10 . The recreational inhalation device as claimed in  claim 5 , wherein each baffle is laterally and longitudinally aligned with adjacent baffles, and each recess is laterally and longitudinally aligned with adjacent baffles and recesses. 
     
     
         11 . (canceled) 
     
     
         12 . The recreational inhalation device as claimed in  claim 1 , wherein the device body tapers distally in a direction away from the passage to promote heat transfer away from the passage to the environment via the device body. 
     
     
         13 . The recreational inhalation device as claimed in  claim 12 , wherein the device body tapers in a plurality of directions away from the passage. 
     
     
         14 . The recreational inhalation device as claimed in  claim 1 , further comprising a flow guide at or adjacent to the inlet, the flow guide having at least one fan blade to increase a flow-rate of at least any one of smoke, vapour and air received through the inlet. 
     
     
         15 . The recreational inhalation device as claimed in  claim 6 , wherein the first and second body portions are configured to be attached to and detached from to each other. 
     
     
         16 . The recreational inhalation device as claimed in  claim 15 , wherein the first and second body portions are configured to be attached to and detached from each other via at least one magnetic member on each of the first and second body portions. 
     
     
         17 . The recreational inhalation device as claimed in  claim 1 , wherein the passage has an at least in part tapering lateral extent from the inlet to the outlet to funnel at least one of smoke, vapour and air towards the outlet. 
     
     
         18 . The recreational inhalation device as claimed in  claim 1 , wherein the passage includes an outlet chamber at or adjacent to the outlet, the outlet chamber having a greater lateral extent than an adjacent portion of a shaft portion to decelerate at least one of smoke, vapour and air before reaching the outlet. 
     
     
         19 . The recreational inhalation device as claimed in  claim 1 , wherein the passage includes an inlet chamber at or adjacent to the inlet, the inlet chamber having a greater lateral extent than a shaft portion of the passage to collect and promote mixing of at least one of smoke, vapour and air in use. 
     
     
         20 . The recreational inhalation device as claimed in  claim 19 , wherein the body at or adjacent to the inlet chamber tapers distally so as to form a ridge which extends at least in part around the inlet, said ridge defining a source holder which is fluidly communicable with the pathway, the source holder being for holding a source of at least one of smoke and vapour. 
     
     
         21 . (canceled) 
     
     
         22 . A recreational-inhalation-device part configured to form a recreational inhalation device, the part comprising:
 a device-body part configured to form at least in part a passage between an inlet and an outlet of the recreational inhalation device, the device-body part being adapted to connect to a further device-body part,   the said device-body part having a plurality of baffles configured to be positioned at the passage to form a tortuous pathway between the inlet and outlet.
