Abstract

The utility model discloses a cigarette filter tip in which a poromeric interlayer is arranged, and the poromeric interlayer is filled with activated carbon granules. As the activated carbon granules have strong adsorption power, when a smoker smokes, smoke passes through an activated carbon granules interlayer, most of harmful substances in the smoke are absorbed on the activated carbon granules, and that the content of the harmful substances in the smoke enters in the human body is reduced. The harm of tobacco for the human body is reduced.

Description

Cigarette filter

The utility model relates to the filter tip that a kind of smoking is used.

The filter tip of use on cigarette generally all is sponge system now, because the absorption affinity of sponge is poor, when enfleuraging cigarette, a lot of harmful substances in the cigarette are not adsorbed, and along with smog is drawn onto in the human body, works the mischief for the healthy of people.

The purpose of this utility model provides the big cigarette filter of a kind of absorption affinity, can adsorb most of harmful substance in the cigarette.

The utility model is achieved in that a ventilative interlayer in filter tip, be full of active carbon particle in the ventilative interlayer.

On the filter tip wall at ventilative interlayer place, filter tip is divided into filter tip head and filter tip tail, filter tip head and filter tip tail are that screw thread is combined into the cassette combination.

The utility model is owing to increased an active carbon particle interlayer in cigarette filter, because activated carbon has very strong adsorption capacity, when smoking, smog is by the active carbon particle interlayer, make that most of harmful substance is attracted on the active carbon particle in the smog, make harmful substance minimizing in the smog that enters human body, reduce the harm of cigarette health.

The utility model is owing to be divided into filter tip head and filter tip tail to filter tip on the filter tip wall at ventilative interlayer place, after cigarette filter repeatedly used, the absorption affinity of active carbon particle reduced, at this moment, can change active carbon particle from here, cigarette filter can be used repeatedly.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is the cutaway view of first embodiment of the utility model

Fig. 2 is the structural representation of another embodiment of the utility model

Ventilative interlayer 2 is arranged in filter tip 1 as shown in Figure 1, and being full of in the ventilative interlayer 2 has active carbon particle 8, on the wall of the filter tip 1 at ventilative interlayer 2 places filter tip 1 is divided into filter tip head 4 and filter tip tail 5, and filter tip head 4 and filter tip tail are screw thread combination or cassette combination.

As shown in Figure 2, Fig. 2's is disposable cigarette filter, and a ventilative interlayer 2 is arranged between filter tip 1 and pipe tobacco, and being full of in the ventilative interlayer 2 has active carbon particle 3.

Claims

1. a cigarette filter comprises filter tip [1], it is characterized in that having in the filter tip [1] a ventilative interlayer [2], is full of active carbon particle [3] in the ventilative interlayer [2].

2. cigarette filter according to claim 1 is characterized in that: on the wall of the filter tip [1] that ventilative interlayer [2] is located, filter cigarette [1] is divided into filter tip head [4] and filter tip tail [5], filter tip head [4] and filter tip tail [5] are screw thread combination or cassette combination.
