Description
Technical Field
The utility model belongs to the technical field of the cigarette filter rod, concretely relates to filter rod for heating cigarette.
Background
The "heating cigarette" is the mainstream tobacco product in new type tobacco, and its principle is that the tobacco is low-temp. roasted by using heating equipment, and does not produce combustion.
The special tobacco is heated and roasted by utilizing the heating equipment, and the temperature is controlled to be lower than the burning point, so that the nicotine and various aromatic substances in the tobacco can be roasted, and harmful substances generated by burning are avoided. The cigarette heating equipment has the taste closest to cigarettes, has the unique fragrance of the tobacco, avoids most of toxic and harmful substances generated by high-temperature combustion cracking, and is concerned by wide smokers once coming out.
In the heating cigarette, because the smoke quantity is limited, a filter stick with lower suction resistance and less interception is needed, but because the generated smoke has higher temperature, the traditional cigarette filter stick design can not meet the requirements of low suction resistance and low interception, and the function of reducing the smoke temperature of the heating cigarette to a palatable temperature is not realized. Therefore, how to effectively cool the smoke without affecting the feeling of the smoker is a key problem of the design of the heating cigarette filter stick.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an aim at: the filter stick for heating cigarettes is characterized in that a microporous foaming material is foamed and extruded to form the filter stick, so that the filter stick has good air permeability and heat insulation, is used as a cooling unit of the filter stick, is matched with a smoke channel axially formed in the cooling unit, can effectively reduce the temperature and suction resistance of smoke, and avoids the problem that the outer wall of the cooling unit is scalded.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
a filter stick for heating cigarettes comprises a piece of wrapping paper and a cooling unit wrapped in the wrapping paper, wherein the cooling unit is formed by foaming and then extruding a microporous foaming material, and a smoke channel is axially formed in the cooling unit.
Further limited, the flue gas channel is positioned in the middle of the cooling unit.
Further defined, the flue gas channel is one or more.
Further limiting, the ratio of the cross-sectional area of the flue gas channel to the cross-sectional area of the cooling unit is 0.1-0.5.
Further limit, the weight of the forming paper is 20-80 g/m 2 The air permeability is 50-500 CU. Such structural design through the injecing to the air permeability of shaping paper for the cooling unit can radially adsorb the outside air when being sucked by the user, further strengthens cooling, the thermal-insulated effect of cooling unit.
Further limited, one end of the forming paper, which is close to the tobacco shreds, of the cooling unit is also coated with a hollow pipe. Such structural design separates pipe tobacco and cooling unit through the air hose, can avoid the pipe tobacco or the offal in small, broken bits to a certain extent to cause the problem of shutoff to cooling unit flue gas passageway, and the practicality is stronger.
Adopt above-mentioned technical scheme's utility model, have following advantage:
1. the microporous foaming material has the characteristics of good air permeability and heat insulation after being foamed and extruded, is used as a cooling unit of the filter stick and is matched with a smoke channel axially arranged on the cooling unit, so that the temperature and the suction resistance of smoke can be effectively reduced, and the problem that the outer wall of the cooling unit is scalded is avoided;
2. cut tobacco and cooling unit are separated through the blank pipe, can avoid the cut tobacco or the offal in small, broken bits to a certain extent to cause the problem of shutoff to cooling unit flue gas passageway, and the practicality is stronger.
Drawings
The invention can be further illustrated by means of non-limiting examples given in the figures;
FIG. 1 is a schematic structural view of an embodiment of a filter rod for heating cigarettes according to the present invention;
the main element symbols are as follows:
cooling unit 1, flue gas passageway 2, air hose 3.
Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, wherein like reference numerals are used for similar or identical parts in the drawings or the description, and implementations not shown or described in the drawings are known to those of ordinary skill in the art. In addition, directional terms, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", and the like, used in the embodiments are only directions referring to the drawings, and are not intended to limit the scope of the present invention.
As shown in figure 1, the utility model discloses a filter stick for heating cigarette, including the shaping paper and wrap up cooling unit 1 in the shaping paper, cooling unit 1 is through extrusion after foaming by the micropore expanded material, and flue gas passageway 2 has been seted up to the axial on cooling unit 1.
The flue gas channel 2 is positioned in the middle of the cooling unit 1.
The flue gas channel 2 is one or more.
The ratio of the cross-sectional area of the flue gas channel 2 to the cross-sectional area of the cooling unit 1 is 0.1-0.5.
The quantitative of the molding paper is 20 to 80g/m 2 The air permeability is 50-500 CU. Through the injeciton to the air permeability of shaping paper for cooling unit 1 can radially adsorb the outside air when being smoked by the user, further strengthens cooling, the thermal-insulated effect of cooling unit.
The forming paper is further coated with an empty tube 3 at one end of the cooling unit 1 close to the tobacco shreds. Separate pipe tobacco and cooling unit through air hose 3, can avoid the pipe tobacco or the offal in small, broken bits to a certain extent to cause the problem of shutoff to cooling unit 1 flue gas passageway 2, the practicality is stronger.
In this embodiment, during the use, the flue gas flows into in the flue gas passageway 2 of cooling unit 1 through hollow tube 3, is finally inhaled by the user, and cooling unit 1 uses as cooling, the thermal insulation material to the flue gas.
The filter stick for heating cigarette provided by the utility model is introduced in detail. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
