Abstract

The utility model relates to a cigarette filter used for filtering cigarettes, which is characterized in that a filter chamber is arranged in the smoke tube used for smoking, and activated carbon is chiefly fed into the middle to adsorb the harmful ingredients in the cigarette. The filter body divides into front and back two stages which are threaded and connected at the filter chamber.

Description

Cigarette filter

The utility model is a kind of filter of filter cigarette.

Many people's smokings are arranged in the society now, contain many oxious components such as " nicotines " in the cigarette, smoking has very big harm to human body.

For addressing this problem, the past is used chimney smoking, and common practice now is: load onto sponge and chew filter cigarette on cigarette, but the oxious component of these methods in can not infallible ground filter cigarette still exists very big harm.Chewing filter cigarette with sponge simultaneously, suck a cigarette and throw away a spongy top, is a kind of very big waste to country.

The purpose of this utility model is to provide a kind of improvement to chew the filter of filter cigarette with chimney and sponge, it can adsorb the oxious component in the cigarette effectively, play a role in filtering, simultaneously, because it is very big with the waste of spongy top filter cigarette, and the charcoal itself of living has the character of multiple adsorb, so this filter also plays the saving effect.

The purpose of this utility model is achieved in that the smoking that the past was used is with separated later on to be threaded in the chimney, bore the hole of φ 6mm * 13mm in the middle of the first half, as the filter chamber, powdered activated carbon (not compressing) is filled in the centre, a small amount of foam mat is used at two, filter chamber respectively, in case powder leaks in the suction hole of into running through whole filter.When smoking, by the active carbon in the filter chamber, oxious component therebetween will be absorbed cigarette from inhale the hole.

The utility model just can be used for filter cigarette because only need to put into active carbon in former chimney, so simple in structure.Itself structure of powdered activated carbon in the filter chamber has adsorptivity, and adsorption area is big, and the character that adsorbance is many is so can adsorb the oxious component that is sucked out behind the cigarette lighter in the cigarette effectively.Oxious component in can multiple adsorb cigarette.Its number of times is relevant with the quality of cigarette, and the cigarette of different quality contains harmful composition amount difference, and when charcoal absorption was saturated, the smoker felt to sniff in the time of can not inhaling and should change active carbon.

The concrete structure of utility model is drawn by following embodiment and accompanying drawing thereof.

Fig. 1 is the profile according to the cigarette filter that the utility model proposes.

Describe details in detail below in conjunction with Fig. 1 according to the concrete filter that the utility model proposes.

This filter comprises a housing main body (1), have in the main body φ 2mm the suction hole (2) of running through main body it be that screw thread 10mm * 1(6) one of cigarettes is that gradient is 4 degree through the filter chamber (3) of a long 13mm of φ 6mm and sponge (4) and active carbon (5) at the main body linkage section, bore is 9mm, is the metal liner (7) of 12.5mm deeply

Claims

1, cigarette filter is a kind of filter of oxious component in the filter cigarette during in order to smoking, this filter divides two sections, connect with screw thread (6), there is a suction hole to run through main body (1) and filter chamber (3) in the filter, it is characterized in that active carbon (5) is arranged in the filter chamber (3), there is liner sponge (4) at its two.

2, filter according to claim 1 is characterized in that active carbon (5) communicates with suction hole (2) in filter chamber (3).

3, according to claim 1,2 described filters, it is characterized in that active carbon fills the filter chamber, do not compress and inhale the hole and communicate.
