Sidestream smoke removal device and control method thereof

Abstract

Provided herein are a sidestream smoke removal device and a control method thereof. The sidestream smoke removal device according to some embodiments of the present disclosure includes a housing in which a smoking space is formed, an article insertion portion which is disposed at one end of the housing and forms an opening for insertion of a smoking article into the smoking space, an ignition portion which is configured to ignite the smoking article inserted into the smoking space, a sidestream smoke processing portion which is configured to process sidestream smoke generated from the smoking article inserted into the smoking space, and a cutting portion. The cutting portion may provide a cutting function for the smoking article inserted into the smoking space and thus ensure a convenient, safe extinguishing function.

What is claimed is: 
     
         1 . A sidestream smoke removal device comprising:
 a housing in which a smoking space is formed;   an article insertion portion disposed at one end of the housing and including an opening for insertion of a smoking article into the smoking space;   an ignition portion configured to ignite the smoking article inserted into the smoking space;   a sidestream smoke processing portion configured to process sidestream smoke generated from the smoking article inserted into the smoking space; and   a cutting portion configured to cut the smoking article inserted into the smoking space.   
     
     
         2 . The sidestream smoke removal device of  claim 1 , wherein:
 a push-type button is disposed on an outer surface of the housing; and   the cutting portion is configured to cut the inserted smoking article as an external force is applied to the push-type button.   
     
     
         3 . The sidestream smoke removal device of  claim 1 , wherein the cutting portion is configured to cut the inserted smoking article as an external force twisting the housing is applied to the housing. 
     
     
         4 . The sidestream smoke removal device of  claim 1 , wherein the cutting portion is configured to cut the inserted smoking article as an external force stretching or contracting the housing is applied to the housing. 
     
     
         5 . The sidestream smoke removal device of  claim 1 , wherein the cutting portion includes a plurality of cutting blades, has an opening formed therein, and is configured to cut the inserted smoking article as the plurality of cutting blades close in a state in which the smoking article is placed to pass through the opening. 
     
     
         6 . The sidestream smoke removal device of  claim 1 , wherein:
 the cutting portion includes a plurality of cutting blades, has an opening formed therein, and is configured to cut the inserted smoking article as the plurality of cutting blades move in a state in which the smoking article is placed to pass through the opening; and   as the plurality of cutting blades move, an overlapping region between the plurality of cutting blades is increased and a size of the opening is reduced.   
     
     
         7 . The sidestream smoke removal device of  claim 1 , wherein the cutting portion is disposed at a fixed position to cut a particular portion of the inserted smoking article. 
     
     
         8 . The sidestream smoke removal device of  claim 1 , wherein the cutting portion is configured to be movable. 
     
     
         9 . The sidestream smoke removal device of  claim 1 , wherein the sidestream smoke processing portion includes:
 a filter structure configured to filter the sidestream smoke; and   an exhaust fan configured to exhaust the filtered sidestream smoke.   
     
     
         10 . The sidestream smoke removal device of  claim 1 , wherein a vent through which outside air enters is formed in the housing. 
     
     
         11 . The sidestream smoke removal device of  claim 1 , further comprising:
 a temperature sensor disposed to measure a temperature near a downstream end of a smoking material portion of the inserted smoking article; and   a controller configured to detect an end of smoking based on the temperature measured by the temperature sensor.   
     
     
         12 . The sidestream smoke removal device of  claim 1 , wherein:
 a vent through which outside air enters is formed in the housing;   the sidestream smoke processing portion includes an exhaust fan configured to exhaust the sidestream smoke; and   the sidestream smoke removal device further comprises a controller configured to, in response to detecting an end of smoking, close the vent and stop operation of the exhaust fan.
