Detailed Description
Example 1
A tobacco capsule suitable for heating non-combustible cigarette smoking device, as shown in figures 1-3, comprises a first capsule section 1 and a second capsule section 2 which are composed of hollow capsule shells, wherein the first capsule section and the second capsule section can be matched into an integral structure, such as matched through a locking structure; the first capsule section capsule cavity is filled with powdery or granular tobacco raw materials 8, and the second capsule section capsule cavity is internally provided with cigarette filter tow; the side surface of the cigarette filter tow is attached to the capsule wall of the second capsule section, and the tobacco raw material fills the gap between the cigarette filter tow and the capsule wall of the second capsule section, so that the capsule shell is tightly contacted with a smoking device, and the heat transfer efficiency is improved; the hollow capsule shell is provided with a smoke circulation channel 3 for smoke circulation so as to enable consumers to suck.
The tobacco raw material adopted in the application is powder or granular material obtained by crushing common re-baked tobacco leaves and adding raw materials such as combustion improver, essence, spice and preservative. The combustion improver is preferably glycerin, wherein the glycerin content is 20% -30% (mass fraction) of the tobacco raw material. The particle size of the tobacco material is preferably 20-80 mesh. The tobacco raw material is required to fully fill the gap between the cigarette filter tow 5 and the capsule wall of the second capsule section, so that the tobacco capsule keeps a certain shape and is tightly attached to the smoking device, and the heat transfer efficiency is improved.
The cigarette filter tow is arranged inside the capsule, so that tobacco raw materials can be filled in the capsule, and the heat conduction efficiency is improved. If the tobacco material is arranged outside the capsule, the composite structure is complex, the tobacco material is easy to fill the capsule completely, the capsule shell is easy to loosen and deform, the capsule shell cannot be well attached to a sucking device, and the heat conduction efficiency is reduced. The specific reasons are that when the tobacco raw materials are filled in the capsules, a loading tool is generally adopted, when the filling quantity is reached and the capsules are filled, partial tobacco raw materials are very easy to be discharged from the capsules along with the loading tool when the loading tool is disassembled, so that the capsules cannot be filled in the capsules; the cigarette filter tow is arranged inside the capsule, the device is simple, the pressure of the cigarette filter tow to the tobacco raw material can be utilized, the tobacco raw material can be completely filled in the capsule, the tobacco raw material can be in a compacted state, the capsule shell can be kept in shape more easily, and deformation does not occur.
The capsule shell material in the application is made of materials resistant to the high temperature of more than 250 ℃, and can not release toxic and harmful substances when being heated to 300 ℃ for use, and can generate bad smell which influences the sucking feeling, and the capsule shell material is insoluble in glycerin. Preferably Polyetherketone (PEK) or polyphenylene sulfide (PPS), which are used in comparison to the gelatin materials commonly used in conventional capsules, can not only resist the high temperature of more than 250 ℃, but also is not easy to deform at high temperature, thereby being convenient for heat conduction.
Air holes can be arranged on the upper end face and the lower end face or the side face of the capsule, so that a smoke circulation channel is formed, and smoke can escape from the capsule for consumers to inhale. The size of the air hole is limited by the fact that the tobacco raw material does not leak and the suction requirement can be met. If the selected capsule shell material has natural air permeability, the requirement of sucking can be met, and no additional perforation is needed.
The tobacco capsules may be in a variety of shapes, such as cylindrical, gear, petal or hexagonal.
Because the special smoking device is repeatedly used, the tobacco capsules can be easily taken out from the special smoking device before and after use.

The first capsule section 1 and the second capsule section 2 are connected through a lock catch; the length of the lock catch is 10-15mm; the upper part of the first capsule section is provided with a diameter contraction section 4 which is used as the inner wall of the lock catch; the second capsule section is not filled with cigarette filter tow 5, and is matched with the diameter contraction section as a lock catch outer wall.
One specific size that can be selected is: the length of the capsule shell (the diameter of the outer wall is 7.4mm, the diameter of the inner wall is 7.0mm, the wall thickness of the capsule wall is 0.2 mm) of the second capsule section (the upper half section) is 30-35mm, and a 20mm long cigarette filter tow (the diameter is 7.0 mm) is arranged in the capsule shell, and one end of the cigarette filter tow is attached to the inner wall of the cylindrical end face of the upper half section capsule shell. The upper half capsule shell is provided with a filter core part (10-15 mm) without filling and is used as the outer wall of the lock catch. Namely the part of the total length (30-35 mm) of the upper half capsule shell minus the built-in 20mm long cigarette filter core forms the outer wall of the lock catch, and the total length of the part is 10-15mm.
The first capsule section (lower section) has a capsule shell length of 30mm and is divided into a locking part (diameter-contracted section) and a non-locking part. The lock catch part is positioned at the upper end and is buckled with the non-filled cigarette filter tow part of the upper half capsule in a molded product, the length of the lock catch part is 10mm, the diameter of the outer wall of the lock catch part is 7.2mm (the lock catch is made to be compact by being larger than the diameter of the inner wall of the upper half by 0.2 mm), the diameter of the inner wall is 6.8mm, the wall thickness is 0.2mm, the diameter of the outer wall of the lower half is 20mm, the diameter of the inner wall is 7.4mm, and the wall thickness is 0.2mm.
As shown in fig. 4, the cigarette filter tow is provided with two sections, the first section of cigarette filter tow is 7 mm long and 7.0mm in diameter, the second section of cigarette filter tow is 6.8mm in diameter and is in accordance with the inner diameter of the lower half capsule locking part, and the second section of cigarette filter tow can extend into the lower half capsule locking part to give greater pressure to tobacco raw materials, so that the capsule shell is less prone to deformation.
The capsule shell may be formed by injection molding. And punching holes at two ends of the molded capsule shell cylinder in a laser punching mode. The pore size density is 3-4/mm, the pores can be round and square, and the maximum diameter is 0.2mm.
