[0002] In the prior art, the filter rod of the cigarette is made of diacetate fiber tow, which mainly mechanically filters the particulate matter in the smoke. However, the cigarette butts left after smoking are difficult to degrade, which has a great impact on the environment. Moreover, after the smoke is filtered by the diacetate fiber tow, a considerable amount of harmful components will still be inhaled into the human body. Therefore, how to improve the filtering and adsorption capacity of the filter rod is an urgent problem to be solved.

[0016] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of the present application. The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the drawings:

[0018] Figure 2 for Figure 1 Schematic diagram of the structure of the filter rod core paper shown. DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0021] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.
[0022] like Figure 1 As shown, the filter rod provided by the embodiment of the utility model comprises a plug-in paper 20 and a filter rod core paper 10. The filter rod core paper 10 is wound inside the plug-in paper 20 to filter the smoke. Figure 2 As shown, the filter plug core paper 10 includes a core paper body 11 and a microporous coating 12 coated on the surface of at least one side of the core paper body 11. The microporous coating 12 has adsorption pores.
[0023] The surface of the core paper body 11 of the filter rod core paper 10 of the embodiment of the utility model is coated with a microporous coating 12, and the microporous coating 12 has adsorption holes, which adsorb harmful substances in the flue gas (such as carbon monoxide, nitrosamines, polycyclic aromatic hydrocarbons, benzopyrene, phenolic substances, etc.), thereby improving the filtering and adsorption capacity of the filter rod. The adsorption of the above-mentioned harmful substances can reduce the harmful components inhaled into the human body, making the flue gas cleaner. In addition, the filter rod core paper 10 is degradable, which can reduce the pollution to the environment after the suction is completed.
[0024] In some embodiments, both sides of the core paper body 11 are coated with a microporous coating 12. Both sides of the core paper body 11 are coated with a microporous coating 12, so that when the smoke passes through the smoke channel formed by winding the filter rod core paper 10, it will be adsorbed by the microporous coating 12, thereby further improving the filtering and adsorption capacity of the filter rod.
[0025] In some embodiments, the material of the microporous coating 12 includes zeolite. Specifically, the zeolite is sprayed on the surface of the core paper body 11, and then wrinkled and made into a filter rod using a roll paper rod forming machine. Using zeolite to form the microporous coating 12 can effectively improve the taste of the paper filter rod and improve the sensory quality of the cigarette. The manufacturing process of the filter rod core paper 10 of the utility model embodiment is simple, easy to operate, and suitable for industrial mass production.
[0026] Moreover, zeolite has excellent properties such as adsorption, ion exchange, catalysis, zeolite molecular sieve, acid and alkali resistance, and high temperature resistance. The interior of zeolite is full of tiny holes and channels, which makes zeolite have a unique molecular sieve effect. Zeolite has a unique structure and a large internal surface area. The specific surface area per gram of zeolite can reach 355-1000m2, so the zeolite has a large adsorption capacity for ions. Zeolite molecular sieve can be used as an adsorbent and catalyst to reduce the content of harmful substances such as nitrosamines, polycyclic aromatic hydrocarbons, benzopyrene, and carbon monoxide in cigarette smoke. At the same time, zeolite does not burn, does not produce smoke impurities, and is harmless to the human body. It is an excellent cigarette additive.
[0027] In some other embodiments, the material of the microporous coating layer 12 includes montmorillonite. Similarly, the montmorillonite is sprayed on the surface of at least one side of the core paper body 11.
[0028] In some embodiments, the material of the microporous coating layer 12 includes sepiolite. Similarly, the sepiolite is sprayed on the surface of at least one side of the core paper body 11 .
[0029] In other embodiments, the material of the microporous coating 12 includes at least one of zeolite, montmorillonite and sepiolite. For example, the microporous coating 12 can be made by mixing zeolite and montmorillonite. For another example, the microporous coating 12 can also be made by mixing zeolite and sepiolite. For example, the microporous coating 12 is made by mixing sepiolite and montmorillonite. Alternatively, the microporous coating 12 is made by mixing zeolite, montmorillonite and sepiolite.
[0030] The utility model also provides a cigarette, comprising a tobacco segment and the filter rod. The tobacco segment is connected to the filter rod. The cigarette made by the filter rod of the above embodiments has less harmful substances inhaled by consumers, which is more beneficial to human health.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
