Description

Spacer and granule type cigarette that smoking section downstream was used

Technical Field

The utility model belongs to the technical field of heating cigarettes, and particularly relates to a spacer and a particle type cigarette for the downstream of a smoking section.

Background

Particle type cigarette props up is a neotype heating type cigarette in recent years, and it replaces tobacco sheet as smoking material with the granule of fuming, and the granule of fuming is heated more evenly than the tobacco sheet, and smog is also more smooth and easy than tobacco sheet class HNB cigarette along the interparticle clearance diffusion, consequently is liked by the consumer deeply.

The particle cigarette is formed by filling smoking particles into a paper cylinder with a sealed far lip end to form a particle section, and arranging a porous fixing part section (or a gear part), a cooling section (which can be a cavity section with holes or a cavity section filled with cooling materials) and a filtering section at the downstream of the particle section. Because the particles being smoked are loose and fluid, if unrestrained, they will flow into the downstream cavity section when the cigarette is placed horizontally, and these particles flowing downstream will not be heated effectively by the heater, and the smoking effect will be affected, so all particle-type cigarette structures at present are designed with the parts for restraining the particles being smoked from flowing around, wherein the upstream of the particles is usually restrained by the sealing film, and the downstream is restrained by the porous fastener section (or gear piece).

The porous fixing piece section is made of ceramic or silica gel, the outer wall of the porous fixing piece section is firmly adhered to the inner wall of the paper tube through an adhesive, and the center and/or the periphery of the porous fixing piece section are/is provided with axial through holes or ventilation grooves which can allow smoke to pass through but not allow smoke particles to pass through, so that the smoke particles can be blocked and can be transmitted. In addition, when inserting resistance heating element or electromagnetism heating element and carrying out the central heating in the granule section, porous firmware section can also prevent fuming granule from promoting porous firmware section itself and move downstream under the propulsion of heating plate insertion force because of firm adhesion on the fiber container inner wall. However, the presence of the porous anchoring portion increases the overall length of the cigarette, and it is therefore always desirable by those skilled in the art to simplify the structure of the porous anchoring portion and to reduce the volume of the porous anchoring portion.

The present invention has been made to solve the above problems.

SUMMERY OF THE UTILITY MODEL

Herein, "used downstream of the smoking segment" does not impose a restriction on the structure of the "spacer" itself. The spacers herein may be used either downstream of the smoking segment or upstream of the smoking segment.

The utility model provides in a first aspect a spacer for use downstream of a smoking segment, the spacer being generally sheet-like and comprising: the device comprises an annular sheet and a central isolation sheet arranged on one side of the annular sheet;

the edge of one side of the central isolation sheet is an area covered by the annular sheet, the center of the side is an area not covered by the annular sheet, and a through hole or a gap is arranged in the area.

Preferably, the other side of the central spacer is also provided with another ring segment, so that the central spacer is sandwiched between the two ring segments.

Preferably, the central spacer is sandwiched between the two annular sheets by means of bonding.

Preferably, the whole of the isolation sheet is in a shape of a circular sheet or a regular polygon sheet.

Preferably, the area not covered by the ring segment is circular.

Preferably, the slit is in the shape of a circular arc or a broken line.

Preferably, the circular arc is in a shape of "C", and the fold line is in a shape of "Contraband".

Preferably, the isolation sheet material is selected from one or more of paper, polymer film and aluminum foil. For example, the central isolation sheet is made of paper, or a composite material of paper and aluminum foil, or a composite material of paper and polymer film. For example, the ring-shaped sheet is made of paper, or a composite material of paper and aluminum foil, or a composite material of paper and polymer film.

The central spacers themselves have a certain elasticity.

Preferably, the annular sheet and the central isolation sheet are made of paper materials, and the hardness of the annular sheet is greater than that of the central isolation sheet.

The utility model provides a particle cigarette, which comprises a cigarette tube, wherein a smoking section and the isolating sheet of any one of the first aspect at the downstream of the smoking section are arranged in the cigarette tube.

Preferably, the upstream of the smoking segment is also closed by a barrier disc according to any one of the first aspect.

Preferably, when the whole spacer is in the shape of a regular polygon, the diameter of the circumscribed circle of the regular polygon is larger than the inner diameter of the smoke tube, and a gap allowing smoke to flow through is formed between the outer edge of the spacer and the inner wall of the smoke tube;

when the whole isolating sheet is in a circular sheet shape, the outer diameter of the isolating sheet is larger than the inner diameter of the smoke pipe, so that the isolating sheet and the smoke pipe are in interference fit.

The direction of smoke flow within a cigarette during smoking is noted as from "upstream" to "downstream".

When the cigarette is smoked, the end close to the lips of the user is marked as a near lip end, and the end far away from the lips of the user is marked as a far lip end.

The technical scheme can be freely combined on the premise of no contradiction.

Compared with the prior art, the utility model has the following beneficial effects:

1. the utility model provides a spacer which is a sheet material, has smaller volume and reduces the axial length of a cigarette. In addition, the ring segments are harder than the central spacer and can withstand some compression and remain supported in the smoke tube. The central spacer has lower hardness, and is convenient to process a through hole or a gap with smaller size.

2. In the preferred technical scheme, the isolation sheet is made of paper materials, is more environment-friendly than the existing plastic isolation plugging piece, and is beneficial to natural degradation of waste cigarettes.

3. In another aspect of the utility model, spacers may be provided upstream and downstream of the smoking section. The cigarette is especially suitable for air heating type smoking set, namely, the air is heated to about 300 ℃ and then is sent into a smoking section of the cigarette. Therefore, the problem of 'smoke material leakage' caused by the fact that the inserted heating smoking set can bring to cigarettes is completely not needed to be considered, and the heating process can be well and fully completed.

4. In a preferred embodiment, the area of the central isolation sheet 1 covered by the ring sheet 2 may further be provided with zigzag slits arranged in an array, such as "Contraband" slits.

The advantages of the "Contraband" shaped slit are as follows:

when punching, the middle chip removal process of punching the through hole is saved;

the Contraband-shaped gap can not only utilize the elastic action of the spacer paper to better block the blocked particles, but also be opened towards the direction close to the lip end under the action of the suction force and the elastic action of the paper during the suction, and has good effect on the smooth passing of the smoke like a one-way valve combined in parallel;

the width of the Contraband-shaped gap (also called as a square opening) arranged at intervals on one side is slightly larger than that of the round through hole, so that the manufacturing density of the opening cutting die on the paper die cutting plate is reduced, and the manufacturing difficulty is also reduced.

When the whole isolation sheet is made of paper, the manufacturing cost of the paper cutter template is obviously less than the mold opening cost of the plastic part metal mold in the prior art.

5. In a preferred technical solution, arc-shaped slits arranged in an array, such as "C" shaped slits, may also be disposed on the area of the central partition 1 covered by the ring-shaped sheet 2.

The "C" shaped slot has the above-mentioned advantages of the "Contraband" shaped slot, and in addition has the following features:

compared with the Contraband-shaped gap, the C-shaped gap is simpler to manufacture because any one of the two cutting dies is used, the maximum nominal size of actual open holes of the two cutting dies is consistent to ensure the blocking effect on granular materials, and is smaller than the average diameter of granules, and the C-shaped cutting die is formed at one time without the problems that a cutter at the vertical corner of a square hole cutting die is difficult to machine and form or a cutter at the right angle is difficult to machine.

The effect of blocking particles is also better because square holes with the same side length and C-shaped holes with the same diameter have the same maximum nominal opening size, but the diagonal size of Contraband is larger than the diameter of the C-shaped holes, namely the actual hole area of the square holes is larger than the maximum actual size of the C-shaped holes, so that the blocking effect of the C-shaped holes is better.

6. In a preferred technical scheme, the whole isolating sheet is in the shape of a regular polygon sheet, the diameter of a regular circumscribed circle of the regular polygon is slightly larger than the inner diameter of the smoke tube, and a gap allowing smoke to flow through is formed between the outer edge of the isolating sheet and the inner wall of the smoke tube. The spacer has the advantages that: because the regular polygon external tangent circle is slightly interfered with the inner diameter of the installed smoke tube, when the isolating sheet is installed in the smoke tube, the slight extrusion deformation of the convex end point of the regular polygon and the point contact connection of the external smoke tube and the non-contact arc section of the regular polygon isolating sheet with proper elastic deformation are utilized. This is easier to install and more reliable in connection than the "line contact" between the disc-shaped partition and the smoke tube in the first to fourth embodiments. Meanwhile, gaps between the regular polygon isolating sheets and the arc of the smoke pipe can be ventilated, and smoke particles can be isolated.

Referring to fig. 1, a spacer II for use downstream of a smoking segment, the spacer II being generally sheet-like and comprising: an annular plate 2 and a central spacer 1 bonded to one side of the annular plate 2. One side is shown in fig. 1 as the back side of the ring segment 2.

The edge of one side of the central isolation sheet 1 is an area covered by the annular sheet 2, the center of the side is an area not covered by the annular sheet 2, the area is circular, and a through hole or a gap 12 is arranged on the area. Fig. 1 shows a circular through hole. The size of the through holes or gaps 12 is smaller than the diameter of the flat diameter of the smoker particles so as to block the smoker particles from entering the cooling section of the cigarette.

In the first embodiment, as shown in fig. 1, the separator II is a circular sheet as a whole. The central spacer 1 is a circular piece having the same size as the entire spacer II. The annular sheet 2 is in the shape of a circular ring sheet, and the annular outer diameter of the annular sheet is equal to the outer diameter of the central spacer 1. When the central isolation sheet 1 and the annular sheet 2 are compounded, the outer edges of the two are completely overlapped.

The material of the central isolation sheet 1 is 25-100 g/m²Tissue paper of (2). The material of the annular sheet 2 is 200-500 g/m²The jam of (2). The purpose is as follows: the hardness of the ring-shaped sheet 2 is greater than that of the central spacer 1, so that when the whole spacer II is filled into the smoke tube through interference fit, the ring-shaped sheet 2 can bear a certain extrusion effect and still be supported in the smoke tube.

In the second embodiment, as shown in fig. 2, the central isolation sheet 1 may also be provided with "Contraband" shaped slits arranged in an array in the area covered by the ring-shaped sheet 2.

The advantages of the "Contraband" shaped slit are as follows:

1. when punching, the middle chip removal process of punching the through hole is saved;

2. the Contraband-shaped gap can not only utilize the elastic action of the paper of the spacer II to better block the blocked particles, but also be opened towards the direction close to the lip end under the action of the suction force and the elastic action of the paper during the suction, and has good effect on the smooth passing of the smoke like a one-way valve combined in parallel;

3. the '21274', which is arranged at intervals on one side, has a larger width than the circular through hole, reduces the manufacturing density of the hole cutting die on the paper die-cutting plate, and also reduces the manufacturing difficulty.

4. When the whole isolation sheet II is made of paper, the manufacturing cost of the paper cutter template is obviously lower than the mold opening cost of the plastic part metal mold in the prior art.

In a third embodiment, as shown in fig. 3, C-shaped slits may be arranged in an array in the area of the central partition 1 covered by the ring-shaped sheet 2.

The C-shaped gap has the advantages of the Contraband-shaped gap, and has the following characteristics:

compared with the Contraband-shaped gap, the cutting die of the C-shaped gap is simpler to manufacture; the effect of blocking particles is better;

in the fourth embodiment, as shown in fig. 4, a second annular plate 2 is also bonded to the other side of the center spacer 1, so that the center spacer 1 is sandwiched between the two annular plates 2. This results in a stronger fixation of the central web 1 and a better support of the two annular webs 2 in the smoke tube. The diameter of the through hole is d.

As shown in fig. 5 to 6, the whole of the spacer II is a regular octagonal plate. The central spacing sheet 1 is a regular octagonal sheet with the same size as the spacing sheet II. The annular sheet 2 is an annular sheet, the annular outer edge line is a regular octagon, and the annular inner edge line is a circle. When the central isolation sheet 1 and the annular sheet 2 are compounded, the outer edges of the two are completely overlapped. In a fifth embodiment, in fig. 5, circular through holes are arranged in an array in the area where the central spacer 1 is covered by the ring-shaped sheet 2. In a sixth embodiment, fig. 6, C-shaped slits are arranged in an array in the area of the central separator 1 covered by the ring-shaped sheet 2.

The seventh embodiment provides a granule type cigarette, a granule type cigarette contains the tobacco pipe, section I, spacer II, cooling section III and filter tip section IV of having set gradually in the tobacco pipe from far lip end to near lip end. The far lip end of the particle cigarette is sealed by a sealing film 3. Of course, other sealing means may be used. The separator II is as shown in the sixth embodiment. The whole spacer II is in the shape of a regular polygon sheet, the diameter of a regular circumscribed circle of the regular polygon is slightly larger than the inner diameter of the smoke tube, and a gap allowing smoke to flow exists between the outer edge of the spacer II and the inner wall of the smoke tube. When the spacer II is installed, one side of the central spacer 1 is close to the smoking section I, and one side of the annular plate 2 is close to the cooling section III. The purpose is as follows: during suction, airflow flows from the far lip end to the near lip end, and the central isolation piece 1 with the C-shaped gap is blocked by the annular piece 2 in the airflow direction and cannot fall off along the airflow direction.

The separator II shown in the sixth embodiment has the advantages that:

because the regular-polygon-shaped tangent circle is slightly more than the inner diameter of the installed smoke tube, when the isolating sheet II is installed in the smoke tube, the slight extrusion deformation of the convex end point of the regular polygon is utilized to connect with the point contact of the non-contact arc section of the external smoke tube and the regular-polygon-shaped isolating sheet II, which is properly elastically deformed. This is easier to install and more reliable in connection than the "line contact" between the disc-shaped spacer II and the smoke tube in the first to fourth embodiments. Meanwhile, the gap between the regular polygon spacer II and the arc of the smoke tube can be ventilated and can separate smoke particles.

An eighth embodiment provides a granule type cigarette, a granule type cigarette contains the tobacco pipe, section I, spacer II, cooling section III and filter tip section IV of fuming have set gradually to nearly lip end from far away in the tobacco pipe. The separator II is as shown in the third embodiment. The smoking section I is internally provided with smoking particles.
