Mouthpiece

Abstract

A non-combustion smoking tool, which uses a real filter cigarette as it is, and which vaporizes nicotine from the tobacco leaves without lighting the product to enable inhalation of the vaporized nicotine, has a problem that a smoker cannot take in 100% of the vaporized nicotine. Thus, a mouthpiece is designed to have an air flow control structure or an air flow control element, or to be combined with a cigarette guide tube, so as to enable the mouthpiece to vary the rate at which the nicotine vaporized from the tobacco leaves is taken in.

1 . A mouthpiece used in combination with a non-combustion smoking tool which uses a real filter cigarette as it is, and uses a heating heater to vaporize nicotine contained in tobacco leaves thereof to enable inhalation of the nicotine, wherein the mouthpiece comprises an air flow control structure or an air flow control element to allow the rate at which the filter absorbs the vaporized nicotine to be varied between zero and an arbitrary rate. 
     
     
         2 . The mouthpiece according to  claim 1 , wherein the air flow control structure or the air flow control element comprises a structure which can hold a fragrance or a material containing water. 
     
     
         3 . The mouthpiece according to  claim 1 , which is used in combination with a cigarette guide tube to fit the mouthpiece. 
     
     
         4 . The mouthpiece according to  claim 3 , further comprising a spacer inserted therein which has a diameter substantially equal to that of the filter cigarette and which serves to make an adjustment to the length substantially equal to that of the filter cigarette so as to enable a filterless cigarette, a cigar or tobacco leaves to be put in the cigarette guide tube for use, wherein the spacer can be designed to hold a fragrance or a material containing water. 
     
     
         5 . The mouthpiece according to  claim 1 , which is used in combination with the non-combustion smoking tool having an outline shape of a pipe. 
     
     
         6 . The mouthpiece according to  claim 1 , which is used in combination with a drive circuit with a built-in heater which has mounted thereon a circuit for generating a voltage waveform from an input voltage and a set temperature (which can be switch input) on printed circuit boards placed to hold a sleeve part of the heater.
