The technical scheme adopted for solving the technical problems is as follows:
the utility model provides a shutter formula tobacco filter, includes filter core and stereoplasm filter tip section of thick bamboo, the filter core includes from near mouth short to near the near-smoke end near-mouth end filter rod, shutter formula filter paper, first section extrusion formula filter rod and second section extrusion formula filter rod that end to end in proper order, stereoplasm filter tip section of thick bamboo parcel is in near-mouth end filter rod and shutter formula filter paper's periphery, shutter formula filter paper includes the framework and sets up a plurality of blade in the framework in parallel, the inboard both ends of blade are installed on the framework inner wall, and its outside is the direction slope setting of first section extrusion formula filter rod, through inclined plane sliding connection between first section extrusion formula filter rod and the second section extrusion formula filter rod, first section extrusion formula filter rod is through controlling its displacement to shutter formula filter paper and is controlled the opening degree of blade.
Optionally, the initial inclination angle of the blade is such that the angle between the blade and the axis of the mouthpiece is not more than 30 °.
Alternatively, all the blades are equally spaced.
Optionally, the width of the blade is equal to the distance between two adjacent blades.
Optionally, the number of the blades is 3-6.
Optionally, the blade is made of diacetate fiber.
Optionally, the length of the shutter filter paper is 2-5mm.
Optionally, the sum of the lengths of the proximal filter rod and the louvered filter paper is equal to the length of the rigid filter cartridge.
Optionally, the inclined plane of the first section of extrusion type filter rod and the axis thereof have an included angle of 20-40 degrees.
Optionally, the near-mouth end filter rod, the first section extrusion type filter rod and the second section extrusion type filter rod are all made of diacetate fiber filter rods.
The invention has the beneficial effects that: according to the invention, the shutter filter paper is arranged between the filter rod at the near mouth end and the first section of extrusion type filter rod, and the first section of extrusion type filter rod and the second section of extrusion type filter rod are connected through the inclined plane; along with the combustion of cigarettes, the tar content in the smoke is gradually increased, and the inclined surfaces of the first section of extrusion type filter stick and the second section of extrusion type filter stick are lightly pressed, so that the first section of extrusion type filter stick moves towards the direction of the shutter type filter paper and pushes the blades obliquely arranged towards the first section of extrusion type filter stick to rotate so as to gradually close the shutter type filter paper, so that the smoke channel of the shutter type filter paper is reduced, the shutter type filter paper gradually participates in the filtering work, and the tar content in the smoke entering the filter stick at the near mouth end can be reduced; at the last stage of cigarette combustion, the tar content in the smoke rises to the maximum value, and at the moment, the first section of extrusion type filter rod is pinched to enable the shutter type filter paper to be completely closed, and the shutter type filter paper integrally participates in the filtering work, so that the filtering effect can be achieved to the greatest extent.
In the smoking process of the cigarettes, the displacement of the first section of extrusion type filter rod is controlled to further control the opening and closing degree of the shutter type filter paper, so that the function of gradually improving the filtering performance is achieved, the same smoke quality in the smoking process from lighting to smoking is ensured, and the tar content is always controlled within a certain range. Of course, if the smoker can also adjust according to own taste, the first section of extrusion type filter stick can not be extruded to ensure that the shutter type filter paper does not participate in the filtering work so as to obtain the highest tar content, and the first section of extrusion type filter stick can be extruded in one step to ensure that the shutter type filter paper integrally participates in the filtering work so as to obtain the lowest tar content.
