Abstract

The utility model relates to a filter used for filtrating smoke tar and nicotine, which is characterized in that sponge, a circular tube and sponge which are connected orderly are arranged in the inner case of the paster to form a cylinder. Three pieces of circular plates are positioned inside the circular tube to divide the tube into four rooms and the four rooms are connected by two cones.

Description

Filter

Affiliated technical field

The utility model relates to the Oil sucking device of nicotine, tar and multiple harmful substances in a kind of filter cigarette.It is the important composition part of cigarette.

Background technology

At present, known cigarette filter tip structure is made of sponge.The material that it is formed is single, and it is limited in one's ability to absorb tar.Because pinching of finger, sponge is yielding, and flue gas easily directly enters the oral cavity with the distortion position, has reduced the ability of sponge filtered tar.

Summary of the invention

In order to overcome the deficiency that existing sponge filter tip absorbs the tar ability, the utility model provides a kind of filter, this filter has a plurality of spaces, number of ways utilizes tar to have the characteristics of viscosity, in flowing through the way, flue gas places obstacles, allow tar, nicotine and multiple harmful substances condense and adsorb in each space and around the barrier, the minimizing tar enters the oral cavity.

The technical scheme that its technical problem that solves the utility model adopts is: sponge mainly absorbs soot dust granule, moisture content, cilium and a part of tar, and 4 spaces and 3 plectanes and 3 groove rings and 2 circular cones are arranged in the pipe.4 spaces in the pipe help smoke circulation, help adhering to aqueous vapor and tar with the cone surface on round tube inner wall, and flue gas goes out from 4 orifice flows of plectane, speed increases, and is subjected to stopping of groove ring, changes to flow to, because tar has viscosity, will be under the groove ring surface adheres to.

The beneficial effects of the utility model are: fully harmful substances minimizing harmful substances such as the tar in the filter cigarette, nicotine enter the oral cavity.

This filter, sponge, pipe, sponge are linked in sequence in paster, it is characterized in that: 1. pipe places in the middle of two sponges, impales with paster, forms a complete filter; 2. sponge, pipe, sponge are the circulation passage of the flue gas of cigarette, and there are 4 spaces pipe inside, three plectanes, three groove rings and two solid circular cones; 3. two circular cones link to each other with three plectanes, and three plectanes are four spaces of part in the pipe.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical section structural map of first embodiment of filter.

Fig. 2 is the vertical section structural map of second embodiment of filter.

Fig. 3 is the planar configuration figure of (3) among Fig. 2, (4), (5).

Fig. 4 is the vertical section structural map of (6) among Fig. 2, (7), (8).

Among Fig. 1,1 sponge, 2 pipes, 3 plectanes, 4 plectanes, 5 plectanes, 6 holes, 7 groove rings, 8 groove rings, 9 groove rings, 10 solid conicals, 11 solid conicals, 12 sponges, 13 pasters, 14 pipe tobaccos.

Among Fig. 1: diameter is 8 millimeters, is higher than 24 hairs.Pipe tobacco (14) is the upper end that is distributed in sponge (1).

Among Fig. 1: sponge (1) diameter is 7.94 millimeters, and height is 4 millimeters.Pipe (2) diameter is 7.94 millimeters, and height is 12 millimeters, wall thickness 0.4 millimeter.Plectane (3), plectane (4), plectane (5) are distributed in pipe (2) inside respectively, be distributed in 2.4 millimeters of pipes (2) respectively from top to bottom, 5.6 millimeters, 8.8 millimeters places, plectane is thick to be 0.3 millimeter, and the little pin hole (6) of 4 symmetries is arranged apart from 0.6 millimeter place of plectane outer rim, and bore dia is 0.3 millimeter.

Groove ring (7), groove ring (8), groove ring (9) places plectane (3) respectively, plectane (4), plectane (5) below is close on the inwall of pipe (2).Among Fig. 4, wherein AB is 0.3 millimeter, and BC is 0.4 millimeter, and CD is 1.1 millimeters, and DE is 0.3 millimeter.

Solid circular cone (10) and solid circular cone (11) are to be distributed in plectane (4) above and below, and solid circular cone (10) end diameter is 3 millimeters, and height is 5.6 millimeters.Solid circular cone (11) end, directly be 3 millimeters, and height is 6.1 millimeters.Paster (13) is sponge (1), sponge (12), and pipe (2) encloses subsides, constitutes a complete filter.

The specific embodiment:

In Fig. 1, after pipe tobacco (14) was lighted, flue gas was subjected to suction to enter sponge (1), and sponge (1) at first absorbs a part of moisture content, dust, materials such as cilium.Afterwards flue gas with and enter next space, along with flue-gas temperature reduces a part of aqueous vapor and tar gradually in pipe (2) inwall and cone (10) surface adhesion.Under suction, flue gas is subjected to stopping of plectane (3) to enter hole (6), because the hole is little, the flow velocity increase is subjected to stopping of groove ring (7), changes flow direction.Flue gas flows through on BC, CD, DE surface, and owing to tar, nicotine have viscosity, a part of tar, Ni Gu are in BC, CD, DE surface condensation and absorption.

In figure (2), flue gas is subjected under the suction, and 4 apertures by every plectane enter next space respectively.In 4 spaces, under suction, flue gas is respectively by plectane (3), plectane (4), plectane (5), in aperture the time flow into next space, the harmful substance in the flue gas is in the surface detention of groove ring.In Fig. 2, flue gas is assembled in 4 spaces, and temperature reduces gradually, and the harmful substance that has viscosity in the flue gas is in groove ring (7), groove ring (8), and groove ring (9) surface, and at round tube inner wall, the cone surface adhesion is got off.
