Problems solved by technology

[0007] In particular: the interval cavity of the interval unit is only at the front end of the cooling unit, and the sequence and various combinations of the interval cavity and the cooling unit cannot be formed, thereby limiting the structural change of the cigarette holder, and is not conducive to the fusion of aerosol in the interval cavity. Remittance and reconciliation

Embodiment 1

[0053] The embedded composite structure includes a spacer unit and a cooling unit, and the cooling unit is embedded in the cavity of the spacer unit. The wall thickness of the spacer unit is 0.30mm, the outer diameter is 7mm, and the hardness is 90%. The cooling unit 3 is a sheet-like structure composed of accumulated particulate matter, which includes gaps through which cigarette smoke can pass. Pa / mm, porosity 82%.

[0054] Connect the embedded composite structure 2 with the acetate mouthpiece 1 and wrap it with molded paper to form a cigarette holder. The acetate mouthpiece 1 is made of acetate tow with a single denier of 20 / total denier of 27,000 and a suction resistance of 8.3 Pa / mm .

[0055] figure 1 It is a schematic diagram of the axis of the cigarette holder in this embodiment, as figure 1As shown, the acetate mouthpiece 1 is connected to one end of the embedded composite structure. In this embodiment, the cooling unit 3 includes a first cooling unit 3-1 and a se...

Embodiment 2

[0058] This implementation differs from Example 1 in that, as figure 2 As shown in the figure, the position of the cooling unit in the spacer unit in the mouthpiece of Example 2 shown in the figure is changed, and other indicators remain unchanged. In this embodiment, the first cooling unit and the second cooling unit are respectively embedded in the head end and the middle position of the spacer unit, and the cavity of the embedded composite structure is divided into a first cavity segment and a second cavity section, that is, the embedded composite structure forms a cooling-cavity-cooling-cavity integrated structure.

[0059] Such as figure 2 The lengths of the cigarette holder shown in Example 2, the acetate mouthpiece, the first cooling unit, the first cavity section, the second cooling unit and the second cavity section are 12mm, 5mm, 8mm, 5mm, and 12mm in sequence.

Embodiment 3

[0061] This implementation differs from Example 1 in that, as figure 2 As shown, in the cigarette holder shown in Example 3 in the figure, there is only the first cooling unit in the spacer unit, and the length of the first cooling unit is 5mm, and other indicators remain unchanged. And the first cooling unit is embedded in the middle of the spacer unit, that is, the embedded composite structure forms a cavity-cooling-cavity integrated structure,

[0062] Such as figure 2 The lengths of the cigarette holder shown in Example 3, the acetate mouthpiece, the first cavity section, the first cooling unit and the second cavity section are 12 mm, 12 mm, 5 mm, and 13 mm in sequence.

Abstract

The invention relates to an embedded composite structure. The embedded composite structure comprises a spacing unit and a cooling unit, the cooling unit is embedded into the cavity of the spacing unit; the cavity of the spacing unit is divided into at least two cavity sections by the cooling unit, the inner wall of the spacing unit is smooth, the roughness RA test value of the pipe wall of the spacing unit is greater than 0.4 micron, the elongation at break of the spacing unit exceeds 30%, the wall material is compact and free of siphonage, and the wall thickness of the spacing unit is 0.10-0.70 mm; the cooling unit is of a sheet structure formed by gathering particles, the structure comprises a gap allowing cigarette smoke to pass through, and the gap is a three-dimensional and nonlineargap. The embedded composite structure has the outstanding characteristics that the pressure drop and the aerosol inlet temperature are adjustable, meanwhile, the compounding difficulty among all the units is reduced, and the compounding efficiency is improved. The structure is compounded with an aerosol forming base material to finish the manufacturing of a two-section aerosol generating article,and if a mouthpiece needs to be reserved, the manufacturing of the three-section aerosol generating article can be finished.

Description

technical field [0001] The invention belongs to the technical field of cigarettes and relates to an embedded composite structure and a cigarette holder. Background technique [0002] CN 104203015 B discloses an aerosol generating article with an aerosol cooling element. Its basic characteristics: An aerosol-generating article comprising a plurality of elements assembled in the form of a rod.
