Abstract
The invention discloses a multi-element composite flow guide cigarette filter rod which comprises a tow filter element and packaging paper. The tow filter element sequentially includes a first filter element, a second filter element and a third filter element from a smoke inlet to a smoke outlet, the peripheral surface of the second filter element is provided with a plurality of flow guide grooves communicated with the outer end face of the second filter element, the pressure drop of the second filter element is higher than 300Pa/cm, and at least one flow guide hole is axially arranged in a central area of the third filter element. When the multi-element composite flow guide cigarette filter rod is applied to smoking a cigarette, smoke is forced to turn to the periphery and mainly passes through the flow guide grooves when reaching the second filter element as the middle of the second filter element is provided with tows and is high in suction resistance while the periphery of the second filter element is provided with the flow guide grooves and is low in suction resistance, most of the smoke does not pass through the peripheral tows and directly escapes from the flow guide holes in the central area when reaching the third filter element as the suction resistance of the center with the flow guide holes is far lower than that of the periphery of the third filter element, so that the color of the filter rod is visually light as compared with the prior art, and the color of the filter rod after smoking is adjusted.
Description
Technical field
The present invention relates to a kind of cigarette, particularly relating to a kind of being provided with can when aspirating automatically to cigarette filter rod and the cigarette of flue gas drainage.
Background technology
In existing cigarette product, filter tip is usually adopted to filter the tar in cigarette mainstream flue gas.Filter structure of the prior art is simple, due to the feature of aerodynamics, when cigarette mainstream flue gas flows through filter stick, centre gas velocity and throughput maximum, and peripheral air stream is fast and throughput is low, see Fig. 1, the lines with arrow in Fig. 1 represent flow line, flow line longer expression flow velocity 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, the effusion of filter stick periphery is less, this makes tow utilization ratio in the middle of filter stick too high, and peripheral tow utilization ratio is lower, thus after causing smoking, filter stick end becomes yellowish-brown, especially mid portion, can affect perception like this.
As can be seen here, after how making smoking, filter stick can not become this fulsome yellowish-brown color and luster, and namely 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 multi-element composite flow guide cigarette filter rod is provided, can voluntarily to flue gas drainage, the color and luster of filter stick after adjustment smoking.Based on this, the present invention also provides a kind of multiple elements design drainage cigarette.
For solving above technical problem, technical scheme of the present invention is:
A kind of multi-element composite flow guide cigarette filter rod, comprise the wrapping paper of tow filter core and coated tow filter core, along smoke inlet to the direction of exhanst gas outlet, described tow filter core comprises first paragraph filter core, second segment filter core, the 3rd section of filter core successively, the outer surface of described second segment filter core is also provided with multiple drainage trough, the outer face conducting of described drainage trough and second segment filter core, the pressure drop of described second segment filter core is more than 300Pa/cm, in the axial direction, the central area of described 3rd section of filter core is provided with at least one conduction hole.In the technical program, be that more than 300Pa/cm is comparatively suitable by the pressure drop of second segment filter core, if pressure drop is too small, have fraction will pass through from second segment filter core centre, namely second segment filter core cannot realize the object changing flue gas flow direction.Preferably, the length of described second segment filter core and described 3rd section of filter core is 5-10mm.
Preferably, described drainage trough is strip groove, and its length direction is arranged along the axis direction of second segment filter core.
Preferably, multiple drainage trough is arranged evenly and at intervals around the axial line of second segment filter core.
Preferably, multiple drainage trough is arranged in parallel.
Preferably, the length of described drainage trough is identical with the length of second segment filter core.
Preferably, the groove depth of described drainage trough is 0.3mm ~ 1mm.
Preferably, described conduction hole is multiple, and the axis of multiple conduction hole is parallel to each other, and multiple conduction hole arranges in line or is that polygon is arranged around the axial line of the 3rd section of filter core.
Preferably, the cross-sectional diameter of described conduction hole is 2-5mm.
Preferably, the length of described conduction hole is less than or equal to the length of the 3rd section of filter core, and the outer face conducting of the outer face of conduction hole and the 3rd section of filter core.
A kind of multiple elements design drainage cigarette of the present invention, comprise tobacco rod and filter stick, described filter stick is aforesaid multi-element composite flow guide cigarette filter rod.
Compared with cigarette of the prior art, multi-element composite flow guide cigarette filter rod of the present invention, comprise the wrapping paper of tow filter core and coated tow filter core, along smoke inlet to the direction of exhanst gas outlet, described tow filter core comprises first paragraph filter core, second segment filter core, the 3rd section of filter core successively, the outer surface of described second segment filter core is also provided with multiple drainage trough, the outer face conducting of described drainage trough and second segment filter core, the pressure drop of described second segment filter core is more than 300Pa/cm, in the axial direction, the central area of described 3rd section of filter core is provided with at least one conduction hole.Thus, when being applied to cigarette smoking, when flue gas arrives second segment filter core, owing to there being tow part in the middle part of it, resistance to suction is very large, and be arranged with drainage trough outward, resistance to suction is very little, force flue gas to the periphery drainage trough turn to, mainly pass through from drainage trough; When arriving the 3rd section of filter core, because central area is provided with conduction hole, its resistance to suction is much smaller than periphery, major part flue gas is without peripheral tow, directly overflow from the conduction hole of central area, thus cause visually filter stick color and luster to shoal relative to prior art, realize the adjustment of filter stick color and luster after smoking.
