Description

Technical Field

[0001] The present application belongs to the technical field of heated cigarettes, and more specifically, relates to a window transparent cooling filter rod and a heated cigarette. Background Art

[0002] As we all know, the basic function of filter rods is to filter smoke, improve the quality of smoking, and ensure the safety of consumers when smoking cigarettes. While meeting these basic functions, innovating the function and structure of filter rods will play an increasingly important role in the differentiated development of cigarette products and brand market operations. Today's technological innovation in cigarette products mainly comes from the innovation of filter technology. Special filter rods, such as capsule filter rods, core filter rods, and rotary filter rods, have been widely used in current traditional cigarette products.

[0003] In addition, the window filter rod is a special type of filter rod, which is very popular among consumers due to its unique appearance. The window filter rod refers to a filter rod with a cavity, and the forming paper wrapped in the cavity is transparent forming paper, so that the structure inside the cavity can be directly observed from the outside, and there are usually particles such as explosive beads in the cavity.

[0004] The window filter rod of traditional cigarettes allows consumers to observe the flow of smoke through a transparent window during the smoking process, which is quite interesting, but it has no cooling ability or has poor cooling ability; however, the cooling section requirements of heated cigarettes are different from those of traditional cigarettes. When the current heated cigarettes that are heated but not burned are smoked in the heater, only part of the filter section (filter rod) is exposed, and most of the cigarette is inside the heater. Since the heating area of ​​the smoking device is around 250-300℃, if it cannot be effectively cooled, it is easy to cause the smoke temperature to be too high, resulting in a poor sensory experience for the smoker. Therefore, the existing window filter rods cannot further meet the needs of consumers, which puts forward certain requirements for the cooling function of the window filter rods. Utility Model Content

[0005] In view of the technical problem that the filter rod in the above-mentioned prior art has a weak cooling ability, the embodiment of the present application aims to provide a window transparent cooling filter rod having a good cooling effect.

[0006] To achieve the above-mentioned purpose, the technical solution adopted in the present application is: to provide a window transparent cooling filter rod, including an acetate fiber filter section and a transparent hollow cooling section; the transparent hollow cooling section includes at least three layers of transparent film tubes and a transparent phase change material arranged between two layers of the transparent film tubes.

[0007] In one embodiment, the transparent film tube is a PET film tube.

[0008] In one embodiment, the total thickness of the transparent film tube is 0.5-21 mm.

[0009] In one embodiment, the transparent hollow cooling section has a length of 30-70 mm and a circumference of 17-25 mm.

[0010] In one embodiment, the transparent hollow cooling section is provided with a plurality of air inlet holes.

[0011] In one embodiment, the air inlet holes are arranged in a row at intervals, the number of the air inlet holes is 2-50, and the ventilation rate of the acetate fiber filter segment ranges from 5% to 80%.

[0012] In one embodiment, the transparent phase change material is a polylactic acid film.

[0013] In one embodiment, a flavor and fragrance layer is coated on the wall of the transparent film tube.

[0014] In one embodiment, a bursting bead is provided in the middle channel of the transparent film tube, and the diameter of the bursting bead is 2.6-3.75 mm.

[0015] Another object of the present application is to provide a heated cigarette, comprising a tobacco segment and the above-mentioned window transparent cooling filter rod, wherein the transparent hollow cooling segment is arranged close to the tobacco segment.

[0016] The beneficial effect of the window transparent cooling filter stick provided in the present application is that the setting of the transparent hollow cooling section can not only observe the formation of aerosol and increase the consumer's smoking experience, but also cool the aerosol through the phase change material to meet the needs of consumers.
