Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette product design, and particularly relates to a modular heated cigarette filter rod. Background Art

[0002] Cigarettes are a type of tobacco product. Tobacco leaves undergo a process of primary roasting, threshing, re-roasting, and shredding before being rolled into cylindrical products of a specific length and diameter. To smoke, one end of the tobacco leaf is ignited and the other end is inhaled, producing smoke. Consumers experience a certain level of nicotine satisfaction through smoking, and the aroma of the burning tobacco is a key factor in choosing between different brands.

[0003] Originally used as a decorative component for the cigarette's mouthpiece, filters have become an essential component of cigarettes, primarily used to remove tar from inhaled smoke and reduce the discomfort experienced by smokers. Filter materials have also diversified from acetate to include grooved tips, dual-composite tips, activated carbon-filled tips, and more.

[0004] During the development of heated cigarette products, filter rods and their structure are one of the key factors affecting the smoke release of heated cigarettes. Due to the unique properties of heated cigarette products, multiple filter rods are often required to achieve multiple filter rod functions such as smoke cooling, airflow disturbance, and filtration. After the filter rod structure is designed according to product requirements, the multiple filter rods need to be twisted and composited on a filter rod composite machine. The prepared multiple filter rods are combined with tobacco segments to form a cigarette.

[0005] For multiple and various specifications, the composite operation using filter rod composite equipment is tedious and complicated. At the same time, for composite filter rods with many specifications and large quantities of composite base rods and multi-specification structural designs, there are problems of long production cycle and high product R&D cost. Utility Model Content

[0006] The purpose of the utility model is to provide a modular heated cigarette filter rod for use in product research and development, so as to solve the problem of long preparation cycle and high cost of multi-element filter rods in the prior art.

The first filter rod unit, the second filter rod unit and the third filter rod unit are all structurally uncovered cylinders. An extension unit, a filter unit and a spoiler unit are respectively provided in the first filter rod unit, the second filter rod unit and the third filter rod unit.

[0009] In this application, the filter tip for holding the extension unit, the filter unit and the spoiler unit is split into multiple detachably connected filter rod units. In this way, composite filter rods of different specifications can be quickly prepared by replacing functional units with different properties inside different filter rod units.

[0010] Furthermore, adjacent ends of the first filter rod unit, the second filter rod unit and the third filter rod unit are each provided with a detachable connection assembly.

[0011] Furthermore, the detachable connection assembly includes an annular magnet, and the adjacent ends of the first filter rod unit and the second filter rod unit are both provided with the annular magnet, and the first filter rod unit and the second filter rod unit are detachably connected based on the annular magnet.

[0012] In the present application, magnetic connection is adopted to quickly realize the assembly and disassembly of the filter rod units.

[0013] Furthermore, the detachable connection assembly includes matching thread structures, which are respectively provided at adjacent ends of the first filter rod unit and the second filter rod unit.

[0014] In the present application, connection and removal are performed by means of threaded connection, which has the advantages of good connection effect and is not easy to loosen.

[0015] Furthermore, the detachable connection assembly includes a matching slot and an insert block, and the slot and the insert block are respectively arranged at adjacent ends of the first filter rod unit and the second filter rod unit.

[0016] Furthermore, limiting rings are provided at the end surfaces of the first filter rod unit and the third filter rod unit that are opposite to each other.

[0017] In the present application, limiting rings are provided at the end faces of the first filter rod unit and the third filter rod unit facing each other, and are used to prevent the assembled composite filter rod from sliding out from both ends.

[0018] The utility model adopting the above technical solution has the following advantages:

[0019] 1. In this application, the filter tip used for the extension unit, the filter unit and the spoiler unit is split into multiple detachably connected filter rod units. In this way, composite filter rods of different specifications can be quickly formed by replacing functional units with different properties inside different filter rod units.
