Description

Smoking section with skirt-edge isolating piece and particle type cigarette

Technical Field

The utility model belongs to heating cigarette field, concretely relates to section of fuming and granule type cigarette with take shirt rim separator.

Background

Granule type cigarette props up is novel 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 tobacco sheet, and smog along the granule clearance diffusion also than tobacco sheet type heating type cigarette more smoothly, 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 usually made of ceramic or silica gel, the outer wall of the porous fixing piece section is in interference fit with the inner wall of the paper tube, and the center and/or the periphery of the porous fixing piece section are/is provided with an axial through hole or a vent groove which can be used for smoke to pass through but not allowing smoke particles to pass through, so that the smoke particles can be blocked and smoke can be transferred. 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.

In order to solve the above problems, the utility model is provided.

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

1. the utility model provides a section of fuming or cigarette with take shirt rim isolation piece, use in the section of fuming to set up the particle of fuming has been realized ventilating when the rear end isolation piece 3 shutoff of the nearly lip section of body 1. The plugging piece at the far lip end of the pipe body 1 comprises two schemes:

in the first embodiment, the blocking element is the same as the rear end spacer 3, and the smoking segment or cigarette is suitable for smoking set with various non-insertion (e.g. circumferential heating) heating modes, especially for air heating: air is preheated using an "air heated" smoking set, the preheated air flowing from the rear end spacer 3 into the smoking segment or cigarette. Furthermore, there is no need to consider the problem of "smoking material leakage" from the cigarettes caused by the insertion of heated smoking articles.

Second, the block piece is a front end spacer 2 having main cuts 211 perpendicular to each other. Therefore, the front end spacer 2 can block the smoke particles and facilitate the insertion of the heating element.

2. The functional relationship between the front end spacer 2 or the rear end spacer 3 and the pipe body 1 is as follows: (1) the skirts (the front end skirt 222 and the rear end skirt 322) of the two isolating pieces and the pipe wall of the pipe body 1 generate elastic extrusion action and form friction force, and accordingly the skirts are used as auxiliary supports for installing and fixing the isolating pieces; (2) the skirts (front skirt 222 and rear skirt 322) increase the axial length of the spacer and are therefore easily loaded into the pipe. When the isolating piece is installed, the side turning and the shell clamping are not easy to happen to the isolating piece.

3. In the preferred technical scheme, body 1, front end isolator 2, 3 materials of rear end isolator are paper materials, and it is more environmental protection than current plastic class isolation shutoff piece, also be favorable to the natural degradation of abandonment cigarette.

4. The design of the valve 315 with a "C" shaped slit has the following advantages:

(1) during punching, the middle chip removal process of punching the through hole is saved;

(2) the valve 315 can not only utilize the elastic action of the rear-end blocking membrane 31 to better block 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 rear-end blocking membrane 31 during suction, and is beneficial to the smooth passing of smoke like a series-parallel combined one-way valve;

(3) in the preferred technical scheme, the annular frame body 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 is formed between the outer edge of the annular frame body and the inner wall of the smoke tube.

5. In the cigarette, the rear skirt 322 is inserted into the cooling section, and the front skirt 222 is inserted into the smoking section. Thus, the axial length of the cigarette is not significantly extended.

6. Specific advantages for the front end spacer 2 structure are as follows:

the central heating element is inserted into the cigarette through the main cut 211. After the central heating element is pulled out, the front end diaphragm 21 part at the main cutting mark 211 can restore to the original state or restore to the original state by the elasticity of the front end diaphragm, and the particle smoking material in the cigarette branch is still blocked, so that the smoking set or the use environment is prevented from being polluted.

In a preferred embodiment, the valve of the present invention has a central cut 212, a vertical cut 213, and a distal cut 214 in addition to the main cut 211. The combination of the above-mentioned cutting marks has the following functions: (1) when the heating smoking set heating element matched with the cigarette of the utility model is a sheet heating element or a cross heating element, when the heating element is inserted, the front end diaphragm 21 can be deformed adaptively by using the natural elasticity of the front end diaphragm along the directions of the central cutting mark 212, the vertical cutting mark 213 and the tail end cutting mark 214, and the front end diaphragm 21 is not easy to be torn; (2) after the sheet type heating element or the cross-shaped heating element is inserted, the front end diaphragm 21 can restore to the original shape or restore to the original shape by the elasticity of the front end diaphragm, and particle fuming materials in the cigarette support are still blocked, so that smoking set or using environment is prevented from being polluted; (3) the cut portion is not completely sealed, and thus air is allowed to flow in during suction.

7. The purpose of arranging a cross-shaped frame opening 221 on the center of the frame main body is as follows: for cigarettes with smaller cigarette diameter, the cross-shaped frame opening (particularly the cross-shaped structure) can strengthen the radial strength of the frame main body and prevent the frame main body and the front end diaphragm 21 from being torn; there is a relative guiding effect for the sheet heating element so that it can be precisely inserted into the main cut 211.

8. The utility model also provides a manufacturing method of above-mentioned section of being fuming can utilize auxiliary device to prepare by hand. The auxiliary device for cigarette assembly is simple, reliable and low in cost. The manufacturing process does not need equipment with higher investment cost, can finish the operation only by simply training an operator, and has low requirement on the operator. In addition, the cigarette production can be improved by a labor-intensive mode, more employment opportunities can be provided, and better social benefits are achieved.

The rear skirt 322 is connected to the annular frame body by a rear crease line 323. The central circular area of the rear end blocking diaphragm 31 is not covered by the annular frame body 32, and a plurality of openable valves 315 are opened in the central circular area. The valve 315 is formed by cutting a "C" shaped slit in the trailing occluding membrane 31. It can be seen in fig. 3 that the distance between the root of the "C" shaped slot and the rear end crease line 323 is m.

The pipe body 1, the front end isolating piece 2 and the rear end isolating piece 3 are coaxially arranged. The edges of the frame opening 221 are rounded curves. Two center cuts 212 are formed at the center of the main cut 211 so as to intersect the main cut 211 at a predetermined angle. The center kerf 212 passes through the center of the main kerf 211. The central cut 212 and the main cut 211 are in a shape of a Chinese character 'mi'.
