  According to the configuration of the present invention, the shape of the articulated pipe is easy to apply to the slim pipe, and has the effect of reinforcing the structure and saving material.

It is a three-dimensional view of Taiwan utility model registration No. M394709. It is a three-dimensional view of the first embodiment of the tobacco filter of the present invention. It is a three-dimensional exploded view of the first embodiment. It is a local exploded sectional view of the first example. It is sectional drawing of a 1st Example. It is a three-dimensional figure of the 2nd Example of the tobacco filter of this invention. It is a three-dimensional figure of the 3rd Example of the tobacco filter of this invention.

Hereinafter, the structure, features, and effects of the present invention will be described in detail with reference to the best embodiments and drawings.

  2 and 3 show a first embodiment of the cigarette filter of the present invention, which is applied to a kind of slim cigarette 1, and includes a mouthpiece 2, a filtration pipe 3, a jacket pipe 4 and a filter component 5. FIG. Consists of.

  As shown in FIGS. 3, 4, and 5, the suction mouth 2 includes a suction part 21, an insertion part 22 connected to the suction part 21, and a suction hole 211 installed in the suction part 21. It is.

  The filtration pipe 3 includes a connection part 31 that is in contact with the insertion part 22, a pipe body 32 that is connected to the connection part 31, and a tar separation part 33 that is installed in the pipe body 32. The pipe body 32 has an open end 321 on the opposite side of the connecting portion 31. The tar separation unit 33 has a stopper 331, two oil reservoir recesses 332 installed at the rear end of the stopper 331, and two air flow holes 333 located at the rear end of the stopper 331. In the first embodiment, the plurality of oil reservoir recesses 332 are installed at positions adjacent to the pipe body 32 and the connecting portion 31 at intervals, and the stopper 331 is installed. The plurality of air flow holes 333 are respectively located in the open portions of the plurality of oil reservoir recesses 332. The insertion portion 22 of the suction mouth 2 and the connection portion 31 of the filtration pipe 3 surround to constitute one filtration space 34.

  The articulated pipe 4 includes a articulated column main body 41 and an installed pipe main body 42. The mandrel main body 41 further includes the filter pipe 3 so that it can be removed, connected to the surrounding wall 411 of the installation pipe 42, and installed in the surrounding wall 411 so as to provide a vent hole 412. These are an annular body 413 and several support ribs 414 installed at equal intervals between the annular body 413 and the surrounding wall 411. The plurality of support ribs 414 extend toward the installation pipe main body 42 and protrude from the torus 413. In the first embodiment, the support column body 41 has three support ribs 414, but the number is not limited.

The installation pipe main body 42 has a slim pipe portion 421 that is hollow so that the slim tobacco 1 can be inserted and communicates with the vent hole 412, and the manipulative column main body 41, and an outer side. A shoulder 422 whose diameter is larger than the outer diameter of the slim pipe portion 421 and several ribs 423. The slim pipe portion 421 has an installation portion 424 for inserting the slim tobacco 1 and a small diameter portion 425 having an inner diameter smaller than the installation portion 424. The small diameter portion 425 surrounds and constitutes an airflow converging portion 426 that communicates with the vent hole 412 of the mandrel main body 41.
The shoulder 422 is adjacent to the shoulder post body 41 and has an outer diameter larger than the outer diameter of the slim pipe portion 421, and the inner diameter of the slim pipe portion 421 faces inward in the radial direction of the shoulder 422. Reduce gradually. In the first embodiment, the plurality of ribs 423 are distributed equiangularly outside the slim pipe portion 421, and the slim pipe portion 421 extends from a portion adjacent to the shoulder 422 to the other end of the slim pipe 421. The structure of the articulated pipe 4 is reinforced by stretching. The outer diameter of the shoulder 422 is larger than the inner diameter of the pipe body 32 of the filtration pipe 3, and when this is combined, the constructed column body 41 is installed on the pipe body 32 of the filtration pipe 3, and the pipe body 32 and the tar It encloses with the separation part 33, and comprises one residence space. Further, the shoulder 422 contacts the open end 321 of the pipe body 32.

  In general use, the slim cigarette 1 is mounted on the mounting portion 424 to keep a certain distance from the vent hole 412. On the other hand, the installation of the airflow converging unit 426 makes it easy for the user to smoke from the slim cigarette 1. However, when slim cigarettes sold in the market do not have a specific size standard and slim cigarettes with a relatively small diameter are used, they directly penetrate the installation portion 424 and the small diameter portion 425 and interfere with the vent hole 412. The plurality of support ribs 414 are arranged to avoid compressing the airflow converging portion 426 and making it difficult to suck it. The plurality of support ribs slightly protrude from the vent hole 412 so that a slight gap is maintained between the slim cigarette 1 and the vent hole 412. Also, by making several small spaces 415 communicating with the vent holes 412 between the plurality of support ribs 414, the flow of smoke becomes smooth.

  The filter component 5 can be a kind of filtering cotton main body, activated carbon, and is installed in the filtering space 34 of the pipe main body 32.

As shown in FIG. 2 and FIG. 5, when combining the whole, the filter component 5 is installed in the filtration pipe 3, and the suction mouth 2 and the articulation pipe 4 are connected to the filtration pipe 3. Cigarette 1 can be installed and used.
When the air is sucked and used, the smoke of the slim cigarette 1 enters the airflow converging portion 426 and enters the stay space 35 through the vent hole 412. By blocking the smoke by the stopper 331, harmful substances such as tar and nicotine accumulate in the plurality of oil reservoir recesses 332, and the remaining smoke further enters the filtration space 34 from the plurality of air flow holes 333, and further filter parts The tar and nicotine remaining in the smoke are filtered again by 5, and the smoke after filtering finally comes out from the suction hole 211.

  FIG. 6 shows a second embodiment of the tobacco filter of the present invention, which is substantially the same as the first embodiment, except that the lengths of the plurality of ribs 423 of the articulated pipe 4 are as follows. It is half the length extending from the shoulder 422 adjacent to the slim pipe part 421 to the slim pipe part 421, compared to the first embodiment, further saving material, and the shading. It also serves to reinforce the structure of the pipe 4.

  FIG. 7 shows a third embodiment of the tobacco filter of the present invention, which is substantially the same as the first embodiment, except that a plurality of ribs 423 installed in the jacket pipe 4 in FIG. And the material can be saved, and the shoulder 422 abuts the open end 321 of the pipe body 32.

  Based on the above description, the features and effects of the tobacco filter of the present invention are listed below:

  1. The present invention has a structure such as a tar separation part 33 and a filter part 5 to sequentially filter harmful substances such as nicotine and tar in tobacco, thereby enhancing the filtration effect.

  2. The present invention can be divided into several parts that can be disassembled: the mouthpiece 2, the filtration pipe 3, the articulated pipe 4, and the filter part 5. As a result, one can be conveniently processed, one is easy to assemble, can effectively reduce the manufacturing cost, and the structure of the filtration pipe 3 also applies to slim tobacco.

  3. Installation of the plurality of support ribs 414 helps to increase the smoke flow space, and prevents the slim cigarette from directly blocking the air flow 412 and stagnation of air flow. It becomes easy.

  4. In the present invention, the articulated pipe 4 is applied to the slim tobacco 1. However, the filtration pipe 3 of the present invention can also be equipped with a articulated pipe 4 having other specifications. For example, it can be installed by replacing the jacket pipe 4 that is applied to tobacco of a general size, and the effect that two uses can be achieved with one thing. With the above-mentioned contents, the object of the present invention can be surely achieved.
