Abstract

The utility model relates to an effective cigarette filter tip composed of a filter tip head, a filter tip tail and a filter core. The filter core is arranged inside a tube of the filter tip head. The filter tip head is combined with the filter tip tail by a screw-thread screwing method or an insertion method. The filter core is a plastic tube with one end closed and the other end opened, and the closed end is provided with air inlet holes. A non-woven fabric or a gauze fabric is arranged inside the plastic tube, and then, active carbon particles which have high efficiency and selective absorption are arranged inside the plastic tube. Acetate fiber or other fiber material is arranged inside the opening of the plastic tube to form the filter core with multi-stage filtration. The utility model has the advantages of good filtering effect, pure fragrance retaining of the cigarette, novel structure, convenient use and sanitation.

Description

Effective cigarette filter

The utility model is that a kind of efficient this Smoke-filter holder belongs to the filter-tip technical field that smoking is used.

The existing filter-tip part that comes with some shortcomings, conclude and get up to have following several respects:

1, filter effect is bad: if any filter-tip make sorbing material with some ore, its adsorption capacity is low, poor filtration effect.

2, do not have selective absorption, cigarette loses original pure fragrance.

3, make the cigarette taint of odour owing to add some drugs in filter-tip or the sorbing material.The smoker is reluctant to accept.

4, the filter-tip complex structure that has uses inconvenient.

5, some filter-tip is unhygienic, produces once more to pollute.

The purpose of this utility model provides a kind of high efficiency filter cigarette holder, with its smoking tar and other harmful poisonous substance in can not only high efficiency elimination cigarette, protection health, but also can keep the pure fragrance of cigarette, makes the smoker enjoy the enjoyment of smoking.

The purpose of this utility model is achieved in that this filter-tip is by cigarette holder head; cigarette holder tail and the filter core of crossing that is contained in the cigarette holder head pipe are formed; twist the combination of closing or peg graft with screw thread between cigarette holder head and the cigarette holder tail; crossing filter core is the plastic tube of end sealing; have one or several air admission holes at the blind end top; closed top end pipe inner top is put into nonwoven or cotton gauze; and then put into the high-efficiency activated carbon granules of making in right amount that strong selectivity absorption is arranged by special process; at the openend of this pipe pack into acetate fiber or polypropylene fibroin or other fibrous material and the mouth of pipe blocked; form the filter core of crossing of a multistage high-efficiency filtration systems; because this filter core is so that flue gas sucks the air admission hole that Sui entered the filter core top by the air admission hole of cigarette holder head when being contained in smoker's smoking in the pipe of cigarette holder head; the multistage abundant filtration smoker who passed through filter core is significantly reduced by the tar in the flue gas in the cigarette holder tail suction inlet and other harmful poisonous substance; thereby protected smoking people's physical and mental health; owing to cross the material of having selected selective absorption in the filter core for use; institute is so that cigarette has also kept original pure fragrance; just removed pungent bitter taste and harmful poisonous substance, low-grade cigarette effect is more obvious.The activated carbon of crossing in the filter core (12) in this high efficiency filter cigarette holder is not general activated carbon, but a kind of strong selectivity absorption property of being made by special process that has is exclusively used in the activated carbon that filters cigarette, this activated carbon has special absorption property to cigarette smoke, promptly tar and the pernicious gas that human body is worked the mischief has extremely strong adsorption capacity, but the fabulous taste that has kept cigarette, this activated carbon shape is that shot-like particle also can be the plates or the column of similar material, cigarette holder head of this high efficiency filter cigarette holder (1) and cigarette holder tail (11) are by non-toxic plastic, lucite, jade and wood materials are made, and also can form with paper material or papery and the collocation of other material.The filter core shell (4) of crossing in this high efficiency filter cigarette holder is to be made by plastics or nonwoven or capsule material.

Because adopt such scheme, this high efficiency filter cigarette holder is compared with existing filter-tip, has following remarkable advantage:

1, good filtration effect; The filtration of the well-designed multistage filtering of flue gas process system, tar wherein and other harmful poisonous substance reduce significantly.

2, owing to selective absorption, thereby keep the pure fragrance of tobacco, got rid of the pungent bitter taste in the cigarette.

3, advanced person rational in infrastructure is easy to use, as long as regularly replaced filter core.

4, health is clean, and the foul of filtration all was present in the filter core.

Accompanying drawing is the general structure cross-sectional schematic, also is an embodiment of the present utility model.

In this embodiment, the utility model is to put into filter core (12) in the pipe of cigarette holder head (1), and then twist with screw thread (9) with cigarette holder tail (11) and to close, exhaust gases passes (10) is arranged in the cigarette holder tail (11), the front end of cigarette holder head (1) is provided with metal dress cigarette holder (2), there is air admission hole (3) at the center of dress cigarette holder (2), and crossing filter core (12) is such formation; The top of crossing filter core shell (4) had filter core air admission hole (5), crossing filter core shell (4) inner top is equipped with nonwoven or cotton gauze or other fibrous material and makes the I level and filter (6), reinstall active carbon granule and make the II level and filter (7) and cross pack into acetate fiber or other fibrous material of the mouth of pipe of filter core shells (4) and make the III level and filter (8), and the mouth of pipe is blocked with strong selectivity absorption.

Another embodiment of the present utility model is: cross the filter core of crossing of the interchangeable one-tenth sleeve structure of filter core (12), promptly with the nonwoven stringing of two one end sealings, put into the active carbon granule of strong selectivity absorption in the pipe, the sealing of two tube opening end suits constitutes then.
