Abstract

The utility model discloses a multi-track cigarette filter tip, which comprises a metal filter core and a metal filter core sleeve. Wherein, the filter core is an irregular hollow tube, which is centrally hermetical. Retaining rings are positioned around wall surface of the hollow tube. A filter clearance is arranged between a top of the retaining ring and an internal wall of the filter core sleeve. Grooves are formed between retaining rings. Based on the structure as above, smokes during cigarette combustion penetrate into the retaining ring on the filter core through a gas inlet at one end for a cigarette holder. The filter clearance between the top of the retaining ring and the internal of the filter core sleeve obstructs smoke flows and retains tar and nicotine into the groove. Due to a plurality of tracks of retaining rings and grooves, filtration by layers is realized. Large total area of these grooves (4 to 5 times larger than prior arts) considerably stores tar and nicotine and prevents tar and nicotine entering into mouth, thus greatly decreasing hazardous cigarette substances absorbed by human body.

Description

A kind of multiple tracks filter-tip

Technical field

The utility model relates to a kind of Cigarette filter tip holder.

Background technology

Cigarette is a kind of harmful substance, and smoke contains carcinogens such as a large amount of nicotines, tar, but for various reasons, the cigarette amateur still is difficult to smoking cessation.So the whole bag of tricks of harmful substance and smoking set just arise at the historic moment in the filtering flue gas.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 adopt a kind of threaded filter core to form long spirality flue, its filter capacity is low, filter effect is not ideal enough.

2. some filter-tip complex structure, the harmful substance of precipitation results in blockage easily, uses inconvenience, also is not easy to clean.

3. the filter-tip that has adds some drugs in sorbing material, cigarette loses original pure fragrance.

The utility model content

The purpose that the utility model relates to is to provide a kind of multiple tracks filter-tip; with harmful substances such as the tar of its smoking in can high efficiency elimination cigarette, nicotines; the protection health; the pure fragrance that not only can keep cigarette; make the smoker enjoy the enjoyment of smoking, and owing to adopt metal structure, durable in use; not fragile, clean also very convenient.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of multiple tracks filter-tip, and it comprises metal filtration core and metal filtration core retainer plate; Filtering core retainer plate is connected in the filtration core retainer plate; Described filter core excessively is an irregular hollow body, sealing in the middle of it; The ante-chamber of crossing filter core is made as the dress cigarette holder, has air admission hole on the terminal perisporium of dress cigarette holder; All wall surfaces at hollow body are provided with balk ring, and the balk ring top is provided with time of filtration with filtering the core retainer plate inner body wall, forms groove between balk ring and the balk ring; The end of crossing filter core is provided with venthole, and venthole is connected with mistake filter core back cavity; The end that filters core retainer plate is a nozzle outlet, and nozzle outlet is connected with mistake filter core back cavity.

The described mistake between filter core and the described filtration core retainer plate afterbody twisted the combination of closing or peg graft by screw thread.Have three air admission holes on the terminal perisporium of described dress cigarette holder.

Described air admission hole is equally distributed.

The front of the air admission hole on the terminal perisporium of described dress cigarette holder is provided with the preceding catch of annular.

The described back of crossing the venthole of filter core end is provided with the back catch of annular.

The time of filtration width of described balk ring top and cigarette holder tail inner body wall is ascending or equidistant from front to back.

The described number of crossing the balk ring on filter core perisporium surface is five.

The described balk ring spacing of crossing filter core perisporium surface is equidistant.

The nozzle outlet outer wall of described filtration core retainer plate end is surrounded by one deck plastics.

The beneficial effects of the utility model are, owing to adopted to cross filter core and filter core retainer plate and constituted Cigarette filter tip holder, and crossing filter core is an irregular hollow body, sealing in the middle of it, all wall surfaces at hollow body are provided with balk ring, the balk ring top is provided with time of filtration with filtering the core retainer plate inner body wall, forms groove between balk ring and the balk ring; After having adopted such structure, the cigarette that cigarette combustion forms flow to first balk ring on the filter core through the terminal air admission hole of dress cigarette holder, and plume has only fraction tar, nicotine to retain after filtering the bounce-back of core retainer plate inwall, because stopping of preceding catch arranged, plume can not overflow; The time of filtration that balk ring top and filtration core retainer plate inner body wall are provided with makes tar, nicotine remain in the groove to the inhibition of plume, because of multiple tracks balk ring and groove are arranged, plays the effect of filtering layer by layer; Because stopping of back catch arranged, residuals can be stayed in the groove, and the gross area because of groove very big (than existing big 4-5 doubly) again is so the tar after the filtering, nicotine storage capacity are big, and be not easy in the suction inlet, thereby the harmful substance that can reduce cigarette is inhaled into human body.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail; But a kind of Cigarette filter tip holder of the present utility model is not limited to embodiment.

Fig. 1 is the organigram of a kind of multiple tracks filter-tip of the utility model;
