Connectable Cigarette Filter

Abstract

A connectable cigarette filter comprises a mouthpiece and a plurality of, or one to two, or two to three filter units connected with the mouthpiece. The mouthpiece is an inclined cylindrical body centrally provided with a stepped aperture. The stepped aperture has a front section formed as a sloped cavity. The inclined cylindrical body has a rear section whose outer surface is provided with a pair of planes. The filter unit is a stepped cylindrical body with a stepped through-hole comprising a large-diameter through-hole and a small-diameter through-hole. The front section of the stepped through-hole is formed as a sloped counterbore. The stepped cylindrical body has a rear section formed as a small-diameter, sloped cylindrical body which is shaped and sized according to the sloped counterbore, so that the small-diameter, sloped cylindrical body of one filter unit is insertable into the sloped counterbore of another filter unit.

1 . A connectable cigarette filter comprising a mouthpiece and a plurality of filter units connected consecutively to the mouthpiece, wherein said mouthpiece further comprising:
 an inclined cylindrical body;   a stepped aperture formed in the center of said inclined cylindrical body;   a sloped cavity formed in a front section of said stepped aperture; and   a pair of planes disposed at the outer surface of a rear section of said inclined cylindrical body;   
       each of said plurality of filter units further comprising:
 a stepped cylindrical body; 
 a stepped through-hole having a front section formed as a large-diameter through-hole and a rear section formed as a small-diameter through-hole, disposed in the center of said stepped cylindrical body; 
 a filter element installed at a border between said large-diameter through-hole and said small-diameter through-hole thereof; 
 a sloped counterbore, disposed at the front section of said stepped through-hole; and 
 a small-diameter, sloped cylindrical body, disposed at a rear section of said stepped cylindrical body, which is shaped and sized to suit said sloped counterbore. 
 
     
     
         2 . The connectable cigarette filter of  claim 1 , wherein said mouthpiece is connected with one or two filter units. 
     
     
         3 . The connectable cigarette filter of  claim 1 , wherein said mouthpiece is connected with two or three filter units. 
     
     
         4 . The connectable cigarette filter as in  claim 1 , wherein the mouthpiece has a specific color for distinguishing the mouthpiece from the filter units.
