Description

Technical Field

[0001] The invention relates to the technical field of cigarette filter rods, and in particular to a special-shaped composite filter rod. Background Art

[0002] The filter rod is an indispensable and key component of the cigarette structure. It is located at one end of the cigarette and plays a vital role in the smoking process. Its main function is to filter out some harmful substances in the smoke, such as nicotine (commonly known as nicotine), tar, and carbon monoxide, by physical or chemical means. These harmful substances not only irritate and damage the respiratory system, but long-term inhalation may also increase the risk of lung cancer, cardiovascular disease and other health problems.

[0003] Using high-efficiency filters can significantly reduce the amount of the above-mentioned harmful substances entering the human body, thereby reducing their negative impact on the body. For occasional smokers, this helps reduce possible discomfort in the short term; while for regular smokers, it can play a protective role to a certain extent, delaying the development of chronic diseases caused by long-term exposure to high levels of toxic gases and particulate matter.

[0004] At present, in the design of traditional filter rods, increasing the contact area usually leads to narrowing of the smoke channel, which in turn affects the smoke flow rate and the smoking experience. Traditional cigarette filters are mainly made of materials such as acetate fiber. Although they have a certain filtering effect, they have limitations. In recent years, with the improvement of environmental protection and health awareness, the market demand for low-harm and high-efficiency filters has increased. Summary of the invention

[0005] The purpose of the present invention is to provide a special-shaped composite filter rod, which is actually intended to solve the problem that when the contact area between smoke and filter element is increased to improve the filtering efficiency of the existing cigarette filter, the smoke flow rate is often affected.

[0006] The present invention solves the above technical problems by the following technical means: A special-shaped composite filter rod, comprising filter rod paper, and kraft paper wrapped outside the filter rod paper for connecting the filter rod and a cigarette, wherein a filter core is wrapped inside the filter rod paper, and the filter core comprises a common filter segment, a first special-shaped filter segment, and a second special-shaped filter segment, one end of the common filter segment is connected to the cigarette, and the other end is connected to one end of the first special-shaped filter segment, the other end of the first special-shaped filter segment is connected to one end of the second special-shaped filter segment, the first special-shaped filter segment is provided with a first special-shaped through hole, a spiral filter core is fixedly provided in the first special-shaped through hole, a through hole is provided on the spiral filter core, and the through hole can increase the contact area between the smoke and the spiral filter core, the second special-shaped filter segment is provided with a second special-shaped through hole, a variable diameter special-shaped through hole is provided in the second special-shaped through hole, a variable diameter filter core is provided in the variable diameter special-shaped through hole, and the variable diameter special-shaped through hole is connected to the first special-shaped through hole.

[0007] Furthermore, the first special-shaped through hole is provided with seven groups of channels, and the first special-shaped through hole is composed of seven groups of hexagons stacked on each other. The stacking of hexagons on each other can increase the stability of the first special-shaped filter segment, and the first filling hole is provided in the gap formed between the first special-shaped through hole and the filter rod paper.

[0008] Furthermore, the second special-shaped through hole is provided with seven groups of channels, and the second special-shaped through hole is composed of seven groups of hexagons stacked on each other. The stacking of hexagons can increase the stability of the second special-shaped filter segment, and a second filling hole is provided in the gap formed between the second special-shaped through hole and the variable-diameter special-shaped through hole.

[0009] Furthermore, the first special-shaped through hole, the second special-shaped through hole and the variable-diameter special-shaped through hole are all made of polypropylene plastic.

[0010] Furthermore, the filter element materials used in the common filter section and the variable-diameter filter element are both bamboo pulp viscose fibers.

[0011] Furthermore, the fillers of the first filling hole and the second filling hole are both made of bamboo pulp viscose fiber.

[0012] Furthermore, the spiral filter element is made of bamboo pulp viscose fiber.

[0013] The beneficial effects of the present invention are embodied in: The present invention adopts a special-shaped structural design, including a variable-diameter special-shaped through hole and a first special-shaped through hole that are interconnected, and is designed with multiple special-shaped channels. The multi-channel design allows the smoke to be more evenly distributed when passing through, thereby improving the filtration efficiency. A spiral filter element with a through hole is provided in the first special-shaped through hole, so that the first special-shaped filter segment can effectively increase the contact area between the smoke and the spiral filter element. The variable-diameter special-shaped through hole has a large front port diameter and a small inlet port diameter, which optimizes the smoke flow path. As the diameter becomes smaller, the flow speed of the smoke increases, ensuring the stability of the smoke flow rate, thereby ensuring the consistency of the cigarette smoking quality, and avoiding the increase in the contact area causing the smoke channel to narrow, thereby affecting the smoke flow rate and smoking experience.
