Abstract
The invention discloses a cigarette filter stick capable of conducting self flow diversion. The cigarette filter stick comprises tow filter element and packaging paper, the tow filter element sequentially comprises a first segment filter element, a second segment filter element, a third segment filter element in the direction from an inlet of smoke to an outlet of the smoke, the second segment filter element comprises an inner element portion and an outer ring portion sleeved on the periphery of the inner element portion, the axis of the inner element portion coincides with that of the outer ring portion, suction resistance of the inner element portion is quite larger than that of the outer ring portion, at least one flow diversion hole is formed in the third segment filter element, a plurality of flow diversion grooves are formed in the peripheral surface of the third segment filter element, and the flow diversion grooves are communicated with the outer end face of the third segment filter element. When the cigarette filter stick is applied to suction of a cigarette, due to the fact that the suction resistance of the inner element portion of the second segment filter element is quite larger than that of the outer ring portion, the smoke mostly passes through the outer ring portion, and when the smoke arrives at the third segment filter element, the suction resistance of the central region and the suction resistance of the periphery are small, most smoke does not pass through tows and is directly escaped from the central region and the periphery, therefore, the color of the filter stick visually becomes shallow, and adjustment on the color of the filter stick after the cigarette is smoked is achieved.
Description
Technical field
The present invention relates to a kind of cigarette, relating in particular to a kind of being provided with can be automatically to the cigarette filter rod of flue gas water conservancy diversion and cigarette when suction.
Background technology
In existing cigarette product, conventionally adopt filter tip to filter the tar in cigarette mainstream flue gas.Filter structure of the prior art is simple, feature due to aerodynamics, when cigarette mainstream flue gas is flowed through filter stick, centre gas velocity and throughput are maximum, and peripheral air stream speed and throughput are low, referring to Fig. 1, the lines with arrow in Fig. 1 represent flow line, the longer expression flow velocity of flow line is larger, and aerosol particle is more.As seen from Figure 1, the cigarette product of prior art, main flume is mainly overflowed from filter stick middle part, filter stick periphery is overflowed less, this makes the middle tow utilization ratio of filter stick too high, and peripheral tow utilization ratio is lower, thereby after causing smoking, filter stick end becomes yellowish-brown, especially mid portion, can affect perception like this.
As can be seen here, how to make smoking after filter stick can not become this fulsome yellowish-brown color and luster, how to regulate the color and luster of filter stick after smoking, this is the current technical issues that need to address in this area.
Summary of the invention
The object of the invention is to, a kind of cigarette filter rod of water conservancy diversion is voluntarily provided, can be voluntarily to flue gas water conservancy diversion, the color and luster of filter stick after adjusting smoking.Based on this, the present invention also provides a kind of cigarette of water conservancy diversion voluntarily.
For solving above technical problem, technical scheme of the present invention is:
A kind of cigarette filter rod of water conservancy diversion voluntarily, the wrapping paper that comprises tow filter core and coated tow filter core, direction along smoke inlet to exhanst gas outlet, described tow filter core comprises first paragraph filter core, second segment filter core, the 3rd section of filter core successively, described second segment filter core comprises inner core, is set in the outer ring portion of inner core periphery, described inner core overlaps with the axial line of outer ring portion, and the resistance to suction of described inner core is much larger than the resistance to suction of outer ring portion; In described the 3rd section of filter core, be also provided with at least one pod apertures that runs through its inner end and outer face, the outer surface of described the 3rd section of filter core is also provided with a plurality of guiding gutters, the outer face conducting of described guiding gutter and the 3rd section of filter core.
Preferably, the length of described second segment filter core is 5-15mm, and described the 3rd section of filter core length is 5-10mm.
Preferably, described inner core is identical with the length of outer ring portion.
Preferably, the ratio of the diameter of described inner core and outer ring portion wall thickness is 2:1-6:1.In the technical program, the ratio of the diameter of inner core and outer ring portion wall thickness is 2:1-6:1, can realize the adjusting of filter stick color and luster after smoking, can not cause extraction difficult again; And if the ratio of the diameter of inner core and outer ring portion wall thickness is while being less than 2:1, be that outer ring portion is thicker, inner core diameter is less, air-flow can be walked around inner core without deflection significantly, cause air-flow to concentrate on center at second segment filter core and the 3rd section of filter core intersection, final air-flow will be overflowed from the 3rd section of filter core centre, cannot realize the adjusting of filter stick color and luster after smoking; And if the ratio ratio of the diameter of inner core and outer ring portion wall thickness is while being greater than 6:1, outer ring portion is thinner, inner core diameter is larger, and during suction, air-flow can only be passed through by narrow and small outer ring portion, and this will cause resistance to suction greatly to increase, and cause extraction difficult.
Preferably, described guiding gutter is strip groove, and its length direction is along the axis direction setting of the 3rd section of filter core.
Preferably, a plurality of guiding gutters arrange evenly and at intervals around the axial line of the 3rd section of filter core.
Preferably, the length of described guiding gutter is identical with the length of the 3rd section of filter core.
Preferably, described pod apertures is cylindrical or the prism bodily form, and the diameter of described pod apertures is 2mm～5mm.
Preferably, the axis parallel of the axial line of described pod apertures and described the 3rd section of filter core or overlap.
The cigarette of a kind of water conservancy diversion voluntarily of the present invention, comprises tobacco rod and filter stick, and described filter stick is the cigarette filter rod of aforesaid water conservancy diversion voluntarily.
Compare with cigarette of the prior art, the cigarette filter rod of water conservancy diversion voluntarily of the present invention, the wrapping paper that comprises tow filter core and coated tow filter core, direction along smoke inlet to exhanst gas outlet, described tow filter core comprises first paragraph filter core, second segment filter core, the 3rd section of filter core successively, described second segment filter core comprises inner core, is set in the outer ring portion of inner core periphery, and described inner core overlaps with the axial line of outer ring portion, and the resistance to suction of described inner core is much larger than the resistance to suction of outer ring portion; In described the 3rd section of filter core, be also provided with at least one pod apertures that runs through its inner end and outer face, the outer surface of described the 3rd section of filter core is also provided with a plurality of guiding gutters, the outer face conducting of described guiding gutter and the 3rd section of filter core, thereby, when being applied to cigarette smoking, when flue gas arrives second segment filter core after first paragraph filter core, because the inner core resistance to suction of second segment filter core is much larger than outer ring portion resistance to suction, thereby flue gas major part is passed through from outer ring portion; While arriving the 3rd section of filter core, due to the setting of conduction hole and drainage trough, the resistance to suction of central area and periphery is all less, most of flue gas is without tow, directly from central area and peripheral effusion, thereby cause visually filter stick color and luster to shoal, realize the adjusting of filter stick color and luster after smoking.
