Dual-use cigarette

Abstract

The present invention discloses a dual-use cigarette, comprising a suckable material segment and a filter tip segment which are wrapped by roll paper, wherein a hollowed segment surrounded by roll paper is disposed between the suckable material segment and the filter tip segment, and the roll paper of the hollowed segment is provided with a plurality of first capillary pores. The dual-use cigarette has the advantages that cold air cannot be sucked when smoking is started, and the burn of a respiratory mucosa caused by high temperature smoke can be avoided.

What is claimed is: 
     
         1 . A dual-use cigarette, characterized by comprising a suckable material segment and a filter tip segment which are wrapped by roll paper, wherein a hollowed segment surrounded by the roll paper is disposed between the suckable material segment and the filter tip segment, and the roll paper of the hollowed segment is provided with a plurality of first capillary pores. 
     
     
         2 . The dual-use cigarette according to  claim 1 , characterized in that the roll paper of the filter tip segment is provided with a plurality of second capillary pores. 
     
     
         3 . The dual-use cigarette according to  claim 2 , characterized in that a diameter of the first capillary pores is smaller than or equal to a diameter of the second capillary pores. 
     
     
         4 . The dual-use cigarette according to  claim 1 , characterized in that the first capillary pores are away from the end of the filter tip segment by 2 mm-3 mm, a degree of aeration of the first capillary pores is 100 CU-600 CU, the first capillary pores are in two rows, and a length of the hollowed segment is 5 mm-35 mm. 
     
     
         5 . The dual-use cigarette according to  claim 1 , characterized in that the suckable material segment is a tobacco product segment. 
     
     
         6 . The dual-use cigarette according to  claim 1 , characterized in that a suckable material in the suckable material segment is filiform, granular or flaky. 
     
     
         7 . The dual-use cigarette according to  claim 1 , characterized in that the roll paper is roll paper for cigarettes. 
     
     
         8 . The dual-use cigarette according to  claim 1 , characterized in that the roll paper is roll paper for cigars. 
     
     
         9 . The dual-use cigarette according to  claim 1 , characterized in that a length of the filter tip segment is 5 mm-25 mm, and a suction resistance of the filter tip segment is 2000 Pa-5000 Pa.
