Shisha

Abstract

A shisha head comprises an air inlet, an air outlet suitable for connection to a shisha, at least one vapourizer and an air flow sensor arranged to detect air flow through the shisha head. The vapourizer is arranged to produce vapour in response to the air flow sensor detecting a flow of air through the shisha head.

         13 . A shisha head according to  claim 1 , wherein the shisha head further comprises an outer casing. 
     
     
         14 . A shisha head according to  claim 13 , wherein the casing is circular in cross section and comprises a first section having a first diameter and a second section having a second diameter larger than the first diameter. 
     
     
         15 . A shisha head according to  claim 14 , wherein the first and second sections are linked by an intermediate tapered section. 
     
     
         16 . A shisha head according to  claim 14 , wherein the first diameter is about 4.5 cm and the second diameter is about 8.5 cm. 
     
     
         17 . A shisha head according to  claim 14 , wherein the shisha head has a height of about 11 cm. 
     
     
         18 . A shisha head according to  claim 14 , wherein the air outlet is located at the centre of the second section. 
     
     
         19 . A shisha head according to  claim 14 , wherein the end of the first section remote from the second section comprises a pair of inner and outer concentric circular walls extending outwardly and defining an annular space between them, wherein the inner circular wall surrounds the air outlet.
