Abstract

The invention discloses a cigarette smoke particle matter trapping filter disc holder, which comprises a holder fixing bracket with a cylindrical structure, and a rotating disc type filter disc fixer. The inner wall of the holder fixing bracket is provided with a ring chute for mounting the rotating disc type filter disc fixer; a through hole for mounting a cigarette interface with a telescopic plug is processed in the ring chute; the axis of the through hole is vertical to the central axis of the ring chute; the central position of the rotating disc type filter disc fixer is provided with a suction hole coaxial with the rotating disc type filter disc fixer; a plurality of smoke channels are formed around the suction hole in a mode of dispersively extending to the periphery of the rotating disc type filter disc fixer; the extension end of each smoke channel is respectively provided with a countersink groove matched with the cigarette interface with the telescopic plug; and a filter disc cabin for accommodating filter discs and a control valve are arranged in each smoke channel.

Description

technical field [0001] The invention belongs to the field of tobacco. Specifically, the invention relates to a filter holder for collecting cigarette smoke particulate matter. The holder can be used for the filter holder on a cigarette smoking machine, and can be Realize the switching of flue gas particulate matter collection filters. technical background [0002] With the in-depth research on the uniformity of sensory quality of cigarettes and smoking and health, the research on the changes of smoke characteristics during cigarette smoking has gradually attracted the interest of researchers. The collection of single-puff smoke is difficult. The smoke collecting part of the existing smoking machine, that is, the filter holder, is fixed behind the cigarette connecting port of the smoking machine. The single-puff smoke can be captured arbitrarily. In order to realize the research on the characteristics of smoke during cigarette smoking, researchers can only collect a certai...
