JPH0794U - Smoking pipe - Google Patents

Abstract

(57) [Summary] [Purpose] Conventional smoking pipes are not satisfactory in their ability to remove harmful substances such as nicotine and tar. Therefore, an object of the present invention is to provide a smoking pipe having a significantly higher ability to remove harmful substances such as nicotine and tar than conventional ones. [Structure] A filter containing chitin or a derivative thereof is incorporated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a smoking pipe.

[0002]

[Prior art]

 Conventionally, smoking pipes and the like having a built-in filter containing ascorbic acid and the like as known from Japanese Utility Model Application Laid-Open No. 61-100998 are known.

[0003]

[Problems to be solved by the device]

 The conventional smoking pipes described above are not satisfactory in their ability to remove harmful substances such as nicotine and tar. Therefore, the object of the present invention is to provide a smoking pipe having a significantly higher ability to remove harmful substances such as nicotine and tar than conventional ones.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the smoking pipe of the present invention is characterized by having a built-in filter containing chitin or a derivative thereof.

[0005]

[Action]

 By incorporating a filter containing chitin or a derivative thereof, nicotine, tar and other harmful substances can be removed by 1.5 to 2 times more than conventional ones.

【Example】

 Embodiments will be described below with reference to the drawings. The pipe 1 of this embodiment is composed of a filter 2, an intermediate body 3, a tip member 4, and a suction member 5. The filter 2 is loaded inside the intermediate body 3, and the tip member 4 is placed in front of the intermediate body 3. However, the suction member 5 is connected to the rear of the intermediate body 3, respectively. Further, the front opening member 4 has a partition wall 7 having a smoke passage hole 6 formed therein so that the cigarette 8 is inserted into the tubular portion in front of the work-in-progress wall 7, and the central portion of the rear surface of the partition wall 7 Is provided with a projecting rod 9 for supporting the center of the front surface of the filter 2. Further, the mouthpiece member 5 is provided therein with an inner cylinder 10 whose front end surface supports the peripheral portion of the rear surface of the filter 2. The filter 2 has a structure in which the outer peripheral surface of a core 11 in which fibers such as acetate are bundled is covered with a thin plastic film 12 such as polypropylene, and the core 11 is made of chitin or its derivative. It is impregnated with or added to what is dissolved in a solvent. Chitin is a nitrogen-containing polysaccharide that forms crustaceans such as crabs and the outer skin of arthropods.

[Effect of device]

 The present invention is as described above, and by incorporating a filter containing chitin or its derivative, harmful substances such as nicotine and tar can be removed significantly more than conventional ones, and smoking It has extremely good results for human health. In the case of the pipe having the structure as in the above embodiment, only the central portion of the front surface of the filter is closed by the projecting rod of the front end member, and only the peripheral portion of the rear surface of the filter is closed by the inner cylinder of the suction member. Since smoke only passes through the entire filter without being biased to a part of the filter, the contact between chitin or its derivative contained in the filter and smoke becomes extremely high. The removal rate increases and the above effects become more prominent.
