Abstract

A double filtering cigarette holder essentially comprises a shell body and a filter core. The double cigarette filter is characterized in that the inner wall of the shell body is provided with a protrusion part, and the annular outer wall of the filter core is inserted on the protrusion part; the annular outer wall of the filter core is thicker than a filter core board; an upper cavity body is formed by the annular outer wall and the upper surface of the filter core board, and a lower cavity body is formed by the annular wall and the lower surface of the filter core board; an upper cavity opening and a lower cavity opening are respectively and symmetrically mounted at the upper and the lower positions of the annular outer wall; a groove is positioned on the outer wall of the filter core between the upper cavity opening and the lower cavity opening; an accelerating filtration channel is formed by the groove and the inner wall of the shell body; the protrusion part on the inner wall of the shell body is opposite to the accelerating filtration channel; the protrusion part and the upper cavity opening are closed and a second filtration channel is formed; a collision wall is positioned at the lower cavity opening of the lower cavity body of the filter core. Effectively using the structure of the inner wall of the shell body and the filter core, the double filtering cigarette holder forms two filtration channels at two different directions and the collision wall, thereby having more ideal filtration effect, more simple structure, and lower manufacturing cost.

Description

A kind of double filtration cigarette holder

Technical field

The utility model relates to the filter-tip that a kind of smoking is used, but especially a kind of cigarette holder of double filtration.

Background technology:

In the daily life, the cigarette that people suck all has filter tip, but because of the effect of filtering limited, therefore the whole bag of tricks and the smoking set of harmful substance just arises at the historic moment in the filtering flue gas, cigarette holder particularly, structure is different, and filter effect is also had nothing in common with each other, so it is low to develop a kind of cost of manufacture, the cigarette holder of good filtration effect just can cater to the masses and hold market.

Summary of the invention

The object of the invention is to change the structure of filter core, and it is combined with the cigarette holder shell, reaches the effect of twice filtration, reduces the harm of tobacco to human body.

The purpose of this utility model is achieved by the following technical solution: a kind of double filtration cigarette holder, mainly comprise housing and filter core, and it is characterized in that: bossing is arranged on the inner walls, and the annular outer wall of filter core is stuck on the bossing; The annular outer wall of filter core is than filter core bolt thickness of slab, upper and lower two faces of annular outer wall and filter core bolt plate form upper cavity, lower chamber respectively, annular outer wall symmetric position up and down is provided with epicoele opening, cavity of resorption opening, filter core outer wall between the opening of upper and lower chamber is provided with groove, this groove and inner walls form the accelerated filtration duct, bossing on the inner walls is over against the accelerated filtration duct, the closed second filtration duct that forms of bossing and cavity of resorption opening, corresponding cavity of resorption opening part is provided with the bump wall in the filter core lower chamber; Bump wall in bossing on the described inner walls, the filter core lower chamber all in the form of a ring; Be provided with a projection in the middle of the described filter core upper cavity; Accelerated filtration duct in the described cigarette holder and second is filtered the duct and is 2～6, and the sectional area summation in described accelerated filtration duct is 0.5～2 square millimeter.

The utility model beneficial effect is: 1, effectively utilize the cigarette holder inner walls and the respective outer side edges of filter core to form different filtration duct of both direction and bump wall, filter effect is better; 2, only be made of the filter core of a cigarette holder housing and an independent moulding, simple in structure, cost of manufacture is low.

Description of drawings:

Fig. 1 is embodiment one cross-sectional view of the present utility model;

Fig. 2 is an embodiment filter core upper cavity of the present utility model visual angle structural representation;

Fig. 3 is an embodiment filter core lower chamber of the present utility model visual angle structural representation;

Fig. 4 is embodiment two generalized sections of the present utility model.

Among the figure, 1, housing; 2, filter core; 3, bossing, 4, annular outer wall, 5, filter core bolt plate; 6, epicoele opening; 7, cavity of resorption opening; 8, groove; 9, accelerated filtration duct; 10, second filter the duct; 11, bump wall; 12, projection; 13, glass marble.

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment one: as Fig. 1, Fig. 2, shown in Figure 3, the housing 1 usefulness transparent material of cigarette holder is made, housing 1 inwall is provided with annular portions 3, filter core 2 can be one-body molded with the mould reverse mould, filter core 2 is clamped on the bossing 3 of inner walls, bossing 3 is over against accelerated filtration duct 9, and cavity of resorption opening 7 forms second with filter core bolt plate 5, bossing 3 and filters the duct; During use, cigarette is inserted cigarette holder, withstand by projection 12, in the sucking process, flue gas enters accelerated filtration duct 9 from epicoele opening 6, and high-speed impact condenses on it tar in bossing 3, finishes for the first time and filters, the residue flue gas condenses tar through impinging upon on the bump wall 11 behind second filtration duct 10 after changing direction once again, finishes for the second time and filters.

Embodiment two: as shown in Figure 4, on the basis of embodiment one, place many pieces of ballotinis 13 in the cigarette holder housing below the lower chamber of this cigarette holder, can cool off the flue gas that condenses by behind the filter element filtering once more like this, filter effect is better.
