Description

A skirted particle-type smoke-generating segment plug and particle-type cigarette stick

technical field

The invention belongs to the technical field of heated cigarettes, and in particular relates to a skirted granule-shaped smoking segment plug and granule-shaped cigarette sticks.

Background technique

Particle-type cigarettes are a new type of heated cigarettes in recent years. They use smoke particles instead of tobacco sheets as smoking materials. Heating-type cigarettes are more smooth, so they are very popular among consumers.

Particle-type cigarettes are usually filled with smoke particles into a paper tube sealed at the far lip end to form a particle section, and a porous solid section (or gear member), cooling section (which can be a cavity with holes) is arranged downstream of the particle section. Section or cavity section is filled with cooling material) and filter section. Since the smoke particles are loose and fluid, if they are not restrained, they will flow into the downstream cavity section when the cigarette is placed horizontally, and these smoke particles flowing downstream will not be effectively heated by the heater , affect the smoke effect, so all the current particle-type cigarette structures are designed with components that restrict the smoke particles so that they do not flow around. gears) to constrain.

The material of the porous solid part is usually ceramic or silica gel, the outer wall of which is in interference fit with the inner wall of the paper tube, and the center and/or outer periphery has an axial through hole or ventilation groove that allows smoke to pass through but does not allow smoke particles to pass through. Smoke particles can in turn transmit smoke. In addition, when the resistance heating sheet or the electromagnetic heating sheet is inserted into the particle section for central heating, the porous solid section is firmly adhered to the inner wall of the paper tube, which can also prevent the smoke particles from pushing the porous solid piece under the insertion force of the heating sheet The segment itself moves downstream. However, the existence of the porous solid section increases the overall length of the cigarette. Therefore, those skilled in the art always hope to simplify the structure of the porous solid section and reduce the volume of the porous solid section.

In order to solve the above problems, the present invention has been proposed.

The second aspect of the present invention provides a particle-type cigarette, the particle-type cigarette includes a smoke pipe, and the particle-type smoking section I and any of the first aspects downstream of the particle-type smoking section I are arranged in the smoke pipe. One of the blocking elements.

Preferably, when the annular frame body is in the shape of a regular polygon sheet, the diameter of the circumscribed circle of the regular polygon is larger than the inner diameter of the smoke pipe, and the distance between the outer edge of the ring frame body and the inner wall of the smoke pipe is There are gaps that allow the passage of smoke;

Preferably, the blocking member described in any one of the first aspect is also provided upstream of the particle-type smoking section I.

The above technical solutions can be freely combined under the premise of no contradiction.

Compared with the prior art, the present invention has the following beneficial effects:

1. The present invention provides a skirted granular smoke-generating block. The function of the skirt is: (1), increase the axial length of the plugging member, so it is easy to fill into the smoke pipe, and it is not easy to roll over and jam; (2), strengthen the supporting function of the plugging member in the smoke pipe, (3 ), because there is friction between the skirt and the smoke pipe, which improves the reliability of the valve being fixed in the smoke pipe.

In addition, the strength of the ring frame body 2 is greater than that of the central spacer, and the ring frame body 2 can bear a certain degree of extrusion and still be supported in the smoke pipe. The diaphragm 1 is weaker, thinner, and more elastic, and it is also convenient to process smaller gaps, and it is also conducive to the rebound of the valve 15 to block the smoke particles.

2. In the preferred technical solution, the ring frame body 2, the diaphragm 1, and the ring base 3 are all made of paper, which is more environmentally friendly than the existing plastic isolation and blocking parts, and is conducive to the natural degradation of waste cigarettes.

3. For the latest type of "air heating" smoking set that first heats the air that will enter the cigarette to a hot state of about 300°C, and then sends it into the heating chamber of the cigarette, if the sealing member of the present invention is used to install it in the smoking section Upstream and downstream, it is also good to send hot air into the cigarette for the heating process. This does not need to consider the problem of "leakage of smoking material" caused by the insertion of the heating element in the contact heating smoking appliance, and the heating process can be fully completed.

4. The design of the valve 15 with a "C" shaped slit has the following advantages:

(1) When drilling, the intermediate chip removal process of drilling through holes is omitted;

(2), the valve 15 can not only use the elastic effect of the diaphragm 1 itself, but also have a better blocking effect on the blocked particles, and at the same time, it is drawn to the proximal lip direction by the suction force and the elastic effect of the diaphragm 1 during suction. Open, like a one-way valve combined in series and parallel, it has a good effect on the smooth passage of flue gas;

(3) It is easier to make the cutter mold with "C" shaped gap; there is no problem that the cutter at the vertical corner of the square hole cutter mold is not easy to process or the cutter at the right angle is not easy to process and is easily damaged.

(4) When the material of the diaphragm 1 is paper, the production cost of the paper knife template is also significantly less than the mold opening cost of the metal mold for plastic parts in the prior art.

5. In the preferred technical solution, the main body of the annular frame is in the shape of a regular polygon, the diameter of the circumscribed circle of the regular polygon is slightly larger than the inner diameter of the smoke pipe, and the outer edge of the main body of the annular frame and the There are gaps between the inner walls of the smoke pipe to allow the smoke to flow. The advantage of the above-mentioned regular polygonal sheet is that: since the regular polygonal circumscribed circle is a little more than the inner diameter of the installed smoke pipe, when the plugging piece is loaded into the smoke pipe, the slight extrusion deformation of the convex end of the regular polygon and the The "point contact" connection of the outer smoke pipe and the non-contact arc section of the regular polygon spacer is properly elastically deformed. This is easier to install than the "line contact" between the disc-shaped annular frame body and the smoke pipe, and the connection and support are reliable. At the same time, the gap between the main body of the regular polygonal ring frame and the arc of the smoke pipe can not only allow ventilation, but also isolate smoke particles.

6. When the blocking member is folded and ready to be installed, in its axial direction, except for the main sheet part, there is only a circle of skirt 22. The skirt 22 arranged upstream of the smoking section will be inserted into the particle type smoking section 1, and the skirt 2 located downstream of the smoking section will be inserted into the cooling section. Therefore, the blocking member does not significantly extend the axial length of the cigarette.
