Abstract
The utility model relates to a liquid-absorbing cigarette gas filter tip. Harmful substance in cigarette gas is absorbed in a physical and chemical mode by utilizing filter cotton 3 containing absorbing liquid in the filter tip. The utility model is characterized in that a core rod 2 and a baffle plate 4 are arranged in the filter tip. The filter cotton 3 is coated on the core rod 2 and is positioned in a cavity formed between the front part 1 of the filter tip and the baffle plate 4. Before a cigarette is inserted, the filter cotton is sealed. When the cigarette is inserted, the core rod 2 is pushed to move and is communicated with a gas path through a longitudinal gas guiding slot on the core rod. The cigarette gas enters the filter cotton 3, and adsorbing action is completed. Then, the cigarette gas rushed out from the gas guiding slot is rushed on a disc on the back end of the core rod. Thus, substance of tar, etc. is condensed on a wall surface. A boss is designed on an inlet of a smoke gas channel at the back part 5 of the filter tip. Evaporated and condensed absorbing liquid is prevented from inhaling into a mouth. A soft material sleeve 6 is added at the back part 5 of the filter tip for improving the taste of the filter tip. The filter tip can absorb and filter nicotine and other harmful chemical substance, decrease the amount of the harmful substance in the cigarette, which enters a human body and ensure good health of the human body.
Description
Affiliated technical field
The utility model relates to a kind of utilization and contains the absorption liquid filter pulp carries out absorbing and filtering to harmful substance in the cigarette gas cigaratte filter.
Background technology
Nearly hundreds of nuisance is arranged except that nicotine in the cigarette gas, many carcinogenic substances that are are wherein arranged.Present filter tip adopts dry type to filter mostly or the structure of condensation deposition is carried out the filtration of cigarette gas, is mainly physical adsorption way, and is primarily aimed at nicotine and adsorbs, and is extremely low to the absorption efficiency of other harmful substance in the cigarette gas.
Summary of the invention
In order to overcome the limitation of physical absorption, the utility model is placed a filter pulp that contains nontoxic absorption liquid in filter tip, utilization is adsorbed in the absorption liquid on the filter pulp, to the harmful substance in the cigarette gas except that carrying out physical absorption, also realize chemisorbed, can carry out absorbing and filtering nicotine and other harmful substance.This filter tip is divided in two parts, and first half inserts cigarette, latter half of being contained in the mouth.Designed the plug baffle arrangement in the filter tip, filter pulp is arranged in the anterior cavity that forms with baffle plate of filter tip, and be coated on the plug, plug is on structure, and partial-length is a shiny surface, part has vertical air slot, the rear end is designed to a disc structure that strengthens, and disk diameter is slightly less than the filter tip internal diameter, and a plug part is positioned at the anterior position, hole of inserting cigarette of filter tip, a part is positioned at filter tip cavity subsequently, and inserts in the baffle plate.When not using, the shiny surface of plug closely contacts with hole on filter tip front portion and the baffle plate and realizes sealing, and the absorption liquid in the filter pulp can not run off.During use, cigarette is inserted the filter tip front portion, promotes simultaneously to move behind the plug, and the air slot position is pushed into the two ends corresponding hole site, connects gas circuit, makes cigarette gas realize absorption function through filter pulp.The cigarette gas of going out from air slot impacts on end disc behind the plug simultaneously, produces the wall chilling action, and material such as tar is condensed on the disk wall.Design a boss in exhaust gases passes porch, filter tip rear portion, to avoid in the absorption liquid suction inlet that evaporative condenser comes out.Filter tip latter half of with the mouth contact site increase by a soft material cover, improve the filter tip mouthfeel.
The beneficial effects of the utility model are, utilize the physics and the chemisorption of filter pulp and absorption liquid, and the coagulation of wall Quench, can reduce the amount of harmful substance suction human body in the cigarette gas greatly, the sealing of absorption liquid before its structural design also can guarantee to use, avoid running off, can prevent in the absorption liquid suction inlet during use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical section structure figure of the preceding state of use of one of the utility model embodiment.
Fig. 2 is one of the utility model embodiment vertical section structure figure in use.
1. filter tip front portions among the figure, 2. plug, 3. filter pulp, 4. baffle plate, 5. filter tip rear portion, 6. soft material cover, 7. cigarette.
The specific embodiment
In the embodiment shown in fig. 1, plug (2) inserts in the filter tip front portion (1), its architectural feature is that the compartment of terrain offered air slot longitudinally, the unslotted position is a shiny surface, the disc structure that plug (2) rear design one strengthens, disk diameter is slightly less than the filter tip internal diameter, the residing position of plug among the figure (2) makes its smooth part go up respective aperture with filter tip front portion (1) and baffle plate (4) and contacts, realize sealing, filter pulp (3) is coated on the plug (2), the cavity that places filter tip front portion (1) and baffle plate (4) to form, absorption liquid can not run off in filter pulp this moment (3).A boss has been designed in inner gas passage porch, filter tip rear portion (5), can avoid in the absorption liquid suction inlet that evaporative condenser comes out.Soft material cover (6) on the filter tip rear portion (5) can improve mouthfeel.
In embodiment illustrated in fig. 2, when cigarette (7) is inserted in the hole of filter tip front portion (1), promoting plug (2) moves to filter tip rear portion (5), make the last vertical air slot position of plug (2) move on to filter tip front portion (1) and the last corresponding hole site place of baffle plate (4), connect gas circuit, cigarette gas enters in the filter pulp (3) that contains absorption liquid through the air slot of plug (2) leading portion, finish the absorbing and filtering function, again on the disk of air slot impact at its rear portion of plug (2) back segment, because the wall chilling action condenses on the wall of disk the materials such as tar in the cigarette gas, enter filter tip rear portion (5) again, in the suction inlet.
Claims (4)
1. a cigaratte filter is provided with the filter pulp that contains absorption liquid in filter tip, and it is characterized in that: filter tip is divided into the front and rear part, indoor design the plug baffle arrangement, filter pulp is arranged in the anterior cavity that forms with baffle plate of filter tip, and is coated on the plug, and there is the soft material cover at the filter tip rear portion.
2. filter tip according to claim 1 is characterized in that: mandrel structure is that the compartment of terrain offers vertical air slot, and unslotted partly is a shiny surface, the disk that plug rear design one strengthens, and its diameter is slightly less than the filter tip internal diameter.
