Description

Cigarette filter unit

The present invention relates to a filter unit, and more particularly to a cigarette filter unit.

In today's society, cigarettes have gradually become a necessity for some people. However, cigarettes contain harmful substances such as nicotine, tar, etc., which cause great harm to the smoker's body. This is to be avoided by the smoker. In order to avoid the influence of harmful substances, commercially available cigarettes will have a filter cotton at the end. However, the filter has limited filtering effect and has an improved space. Moreover, cigarettes of various tastes are rushing to launch, and competition is fierce. For cigarette manufacturers, how to provide cigarettes of different flavors has gradually become a problem.

Taking Taiwan's new patent TWM377872 as an example, a filter material is embedded in the filter cotton, and the filter material is used to adsorb harmful substances. The filter material has a hollow film layer with at least one liquid therein. The liquid has the effect of being able to adsorb harmful substances, so that the smoker can squeeze the filter material to disperse the liquid therein into the filter cotton, thereby improving the filtration effect. However, when the filter material is slid in the filter cotton during extrusion, it is more difficult to crush, so it is often necessary to press the filter cotton several times to release the liquid in the filter medium. However, after repeated extrusion, the filter cotton is often changed seriously. Shape, it becomes difficult to suck. Moreover, the filter material does not provide the effect of changing the flavor of smoking. Therefore, there is still a lack of cigarettes on the market that simultaneously have the function of not damaging the shape of the filter cotton, filtering harmful substances, and improving the flavor of smoking.

Accordingly, it is an object of the present invention to provide a cigarette filter unit that does not damage the shape of the filter, filters harmful substances, and enhances the flavor.

Thus, the cigarette filter unit of the present invention comprises a filter body, a filter material, and a push rod.

The filter body includes a channel formed therein. The passage has a receiving portion and a dispersing portion. The accommodating portion has an open end that communicates with the outside, and a connecting end that communicates with the dispersing portion.

The filter medium is disposed in the receiving portion.

The push rod is disposed on the receiving portion and partially protrudes from the open end, and when the push rod is pressed, at least a portion of the filter material can be forced into the dispersing portion.

The effect of the invention is that when the smoker wants to suck, only the portion protruding from the push rod needs to be pressed, so that the filter material can be dispersed in the dispersion portion without breaking the shape of the filter body, thereby allowing the The air flow of the filter body is forced through the filter to achieve filtration and produce a special flavor.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1, 2 and 3, a first embodiment of the cigarette filter unit 3 of the present invention is directly coupled to a tobacco rod 21 to form a cigarette 2. The tobacco string 21 is formed by curling most of the shredded tobacco 211, and the manufacturing method thereof is conventional, and will not be described herein.

The cigarette filter unit 3 includes a filter body 31, a filter material 32, a dispersing member 34, and a push rod 33.

The filter body 31 is substantially cylindrical and includes a channel 311 formed therein and a central axis L. The channel 311 has a receiving portion 312 and a dispersing portion 313. The accommodating portion 312 extends along the central axis L And having an open end 314 communicating with the outside, and a connecting end 315 communicating with the dispersing portion 313. The dispersing portion 313 extends in the radial direction of the central axis L to form a disk shape. In the present embodiment, the filter body 31 is of a two-section type, and the partitions 313 are defined by being spaced apart from each other, and one of the sections has the receiving portion 312.

The filter material 32 is disposed on the receiving portion 312 and adjacent to the connecting end 315. The filter material 32 is capable of releasing a special aroma and is also capable of being combined to have a function of filtering. The filter material 32 can take a variety of aspects, such as a capsule, a paste, or a stick. When a capsule is employed, the capsule can be filled with a liquid, a gel, a powder, a granular filter bead, or a combination thereof. When a paste is used, the aforementioned gel and powder are prepared. When a rod is used, it is formed by press-bonding the aforementioned powder, granular filter beads or the like. In this embodiment, a liquid-filled capsule is used.

The aforementioned liquid, gel, powder may be prepared from a perfume having a special odor, and the flavor may be selected from the group consisting of mint, spearmint, honey, cream, coffee, tea, cocoa, holly, cardamom, cinnamon, bitter tree, sandalwood Fragrant, ginger, fennel, flowers and fragrances (such as: lavender, vanilla, licorice, jasmine, sage, clove), fruit flavors (such as: lemon, orange, apple, peach, orange, cherry, strawberry, etc.) , or a combination thereof, however, its selection is not limited to the foregoing.

The aforementioned powder and granular filter beads may be selected from the group consisting of activated carbon, molecular sieves (e.g., zeolite), clay, activated alumina, tannin or the like. Powder and granular filter beads not only absorb toxic substances in the gas stream, but also The impurities and particles are adsorbed, thereby changing the flavor at the time of smoking.

The dispersing member 34 is disposed in the filter body 31 and opposite to the connecting end 315 of the receiving portion 312. The dispersing member 34 is embedded in the filter body 31 or embedded in the filter body 31. In the present embodiment, the dispersing member 34 is provided with a lancet 341, and the needle end protrudes into the dispersing portion 313 of the passage 311 and is aligned with the connecting end 315.

The push rod 33 is disposed on the receiving portion 312 and partially protrudes from the open end 314. The push rod 33 includes a retaining portion 331 that is formed at three outer intervals on the outer peripheral surface. The anti-retraction portion 331 can be engaged with the filter body 31 to prevent the push rod 33 from slipping out from the open end 314 of the passage 311. In this embodiment, each anti-backing portion 331 is substantially frustoconical and extends obliquely away from the connecting end 315. Therefore, when the push rod 33 is displaced toward the connecting end 315, because of the defense The retracted portion 331 is inclined in a direction away from the connecting end 315, and thus has a small resistance.

Referring to Figures 3 and 4, pressing the push rod 33 can force at least a portion of the filter material 32 into the dispersion portion 313, bringing the filter material 32 into contact with the dispersing member 34, and forcing the filter material by the action of the dispersing member 34. 32 is dispersed in the dispersion portion 313 of the passage 311. The cross section of the dispersing portion 313 is almost equal to the cross-sectional area of the filter body 31. Therefore, most of the airflow needs to pass through the dispersing portion 313 during smoking, so that the filter material 32 dispersed therein will adsorb toxic substances, Impurities and fine particles, and also can release a special aroma at the same time, further improving the flavor of the smoking cigarette 2.

When the filter material 32 is a capsule, the needle 341 pierces the capsule to cause the substance therein to flow out and disperse into the dispersion portion 313; When the material 32 is a rod, the needle 341 pulverizes the rod to be powdered and dispersed to the dispersion portion 313; and when the filter material 32 is used as a paste, the needle 341 can be used to paste The substance is branched and dispersed to the dispersion portion 313.

In the present embodiment, the filter medium 32 is a capsule, so that after the capsule is punctured, the liquid therein will flow out and be dispersed in the dispersion portion 313, and finally absorbed by the filter body 31.

Through the above description, the advantages of the present invention can be further summarized as follows:

1. When the smoker wants to suck, only the portion protruding from the push rod 33 is pressed, so that the filter material 32 can be dispersed in the dispersion portion 313 without damaging the shape of the filter body 31, thereby allowing the passage of the filter body 31. The air flow of the filter body 31 forcibly traverses the filter material 32 to achieve filtration and produce a special flavor.

Second, the filter material 32 can be selected according to the needs of the user. For example, when only impurities and particles need to be adsorbed to improve the flavor, the powder and granular filter beads can be used, and if a special flavor is required, The fragrance-containing liquid, gel or powder can be used, and therefore, the present invention can be adjusted to various flavors according to the needs of the user.

3. The dispersing member 34 can more accurately distribute the filter material 32 in the dispersing portion 313 of the passage 311, thereby improving the effect of filtering and producing a special flavor.

4. The anti-backing portion 331 can prevent the push rod 33 from slipping out from the open end 314 of the channel 311, so the push rod does not occur during smoking. 33 The risk of ingestion from the open end 314 and ingestion.

Referring to Figures 5 and 6, a second embodiment of the cigarette filter unit 3 of the present invention is provided for a cigarette 2. The cigarette comprises a tobacco rod 21 composed of cut tobacco 211 and a filter 22 connected to the tobacco rod 21.

The structure of the cigarette filter unit 3 of the present embodiment is substantially the same as that of the cigarette filter unit 3 of the first embodiment. The difference is that the embodiment does not need to be directly formed on the cigarette, and the push rod 33 does not have the anti-backup portion 331 ( See Figure 2), and also includes a housing 35.

The outer casing 35 surrounds the filter body 31 and includes a sleeve portion 351 for attaching the filter 22 of the cigarette 2. The socket portion 351 is on the same side as the open end 314 and is longer than a portion of the push rod 33 that protrudes from the open end 314.

Referring to Figures 7 and 8, the socket portion 351 can serve as a guard rail for the push rod 33 to protect the push rod 33 from being pressed when not in use. When the cigarette 2 is attached to the socket portion 351, the cigarette 2 directly presses the push rod 33 to disperse the filter material 32 in the dispersion portion 313 of the passage 311.

Thus, the second embodiment not only achieves the same effects as the first embodiment, but also discloses a cigarette filter unit 3 that does not need to be directly formed on the cigarette 2, which can be independently manufactured and sold. It is more widely used.

In summary, the smoker only needs to press the push rod 33 to disperse the filter material 32 in the filter body 31, thereby forcibly passing the airflow through the filter material 32 to achieve the effect of filtering and producing a special flavor. It is indeed possible to achieve the object of the invention.

However, the above is only the embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and the patent specification of the present invention are still It is within the scope of the patent of the present invention.
