Problems solved by technology

However, the complex structure of the filter tip will undoubtedly greatly increase the cost of cigarettes, and its design structure is modeled after the filtration mode of a water purifier, and the layer-by-layer filtration will cause the smoke to run unsmoothly and affect the smoking experience
Secondly, the filter still only focuses on filtering harmful substances, and does not try to flavor cigarettes

Embodiment 1

[0037] like figure 1 As shown, this embodiment provides a cigarette filter based on a nanofiber structure, including a cellulose acetate filter element 6, one end of the cellulose acetate filter element 6 is provided with a nanofiber aroma-enhancing filter membrane 3; The fragrance filter membrane 3 includes a nanofiber fragrance enhancement filtration membrane core 4 and a nanofiber fragrance enhancement filtration membrane wall 5 surrounding the nanofiber fragrance enhancement filtration membrane core 4 .

[0038] The nanofiber fragrance-increasing filter membrane 3 has a shell structure, and its diameter is the same as that of the cellulose acetate filter element 6 . In this embodiment, the thickness of the nanofiber flavoring filter membrane 3 is 0.8 mm, and the diameter of the cellulose acetate filter element 6 is 8 mm.

[0039] The nanofiber fragrance-increasing filter membrane core 4 is polyvinyl alcohol (PVA, with an average molecular weight of 77,000) dissolved with ...

Embodiment 2

[0046] This embodiment provides a cigarette filter based on a nanofiber structure, which includes a cellulose acetate filter element 6 , and two nanofiber flavoring filter membranes 3 are arranged at one end of the cellulose acetate filter element 6 . The nanofiber fragrance-increasing filtration membrane 3 includes a nanofiber fragrance-enhancing filtration membrane core 4 and a nanofiber fragrance-enhancing filtration membrane wall 5 surrounding the nanofiber fragrance-enhancing filtration membrane core 4 .

[0047] The nanofiber fragrance-increasing filter membrane 3 is a shell structure with a thickness of 1mm, and the diameter of the cellulose acetate filter element 6 is 8mm. The nanofiber flavoring filter membrane core 4 is polyvinyl alcohol (PVA, average molecular weight 77,000) dissolved with a single lemon essence.

[0048] Other structures are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0050] This embodiment provides a kind of cigarette, such as figure 2 As shown, it includes a cigarette body 2 and the cigarette filter 1 described in Embodiment 1 or Embodiment 2, and one end of the cigarette filter 1 provided with a nanofiber aroma-enhancing filter membrane 3 is connected to the cigarette body 2 .

[0051] After the shredded tobacco is burned, high-temperature smoke will be generated inside the tobacco leaf. With the suction pressure at the mouthpiece, the smoke will be transmitted along the shredded tobacco to the mouthpiece. When the higher flue gas temperature passes through the nanofiber aroma-enhancing filter membrane 3, the phase-change material absorbs heat and melts from a solid to a liquid state, and the spices contained in the structure of the nanofiber aroma-enhancing filter membrane core 4 are in contact with the high-temperature flue gas Then the aroma is released. Sufficient high-temperature flue gas generated during the continuous burning of...

Abstract

The invention discloses a cigarette filter based on a nanofiber structure and a cigarette, solves the problems that an existing cigarette filter is poor in aroma durability, liable to lose after beingstored for a long time and poor in filtering performance, and has the effects of filtering harmful substances, realizing long-term storage of perfume and realizing lasting release of aroma at the same time. According to the technical scheme, the cigarette filter comprises a cellulose acetate fiber filter element body, and one or more nanofiber aroma enhancement filter membranes are arranged at one end of the cellulose acetate fiber filter element body; wherein the nanofiber aroma-enhancing filter membrane comprises a nanofiber aroma-enhancing filter membrane core body and a nanofiber aroma-enhancing filter membrane wall body surrounding the periphery of the nanofiber aroma-enhancing filter membrane core body.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a cigarette filter tip and a cigarette based on a nanofiber structure. Background technique [0002] In recent years, with the improvement of residents' economic and living standards and the enhancement of human health and environmental protection awareness, consumers pay more and more attention to consumption experience and physical health. In order to meet the market demand, under the control of the relevant national tobacco department, the release of harmful substances such as nicotine and carbon monoxide contained in cigarettes is strictly controlled. Restricting the intake of smoke and nicotine will inevitably reduce the cigarette smoking experience of consumers to a certain extent. In order to make up for the defect of aroma decline, many tobacco companies have improved and designed new cigarette filter structures and added flavors by spraying on the surface of shredded to...
