Description

A kind of filter tip

The utility model relates to a kind of filter tip.

Cigarette is harmful to be well-known, the ratio of suffering from nasopharyngeal carcinoma because of smoking is also quite high, the excessive harm to human body of smoking is also conducted vigorous propaganda by government on each coal body in recent years, set up the non-smoking area more in public places, to avoid other common people's passive smokings, but because smoking population has arrived suitable quantity, and smoking cessation is a difficult matter concerning common people, have to have to take the second best since can't effect a permanent cure and to have taked the mode of taking stopgap measures: commonly use filter configuration, as shown in Figure 1, it is mainly by a hollow tube 101 and a suction nozzle 102 and constitute, end is established a shrinkage pool 103 and can be plugged for cigarette before this hollow tube 101, shrinkage pool 103 is provided with several through holes 104 and is communicated with the rear end, be inclusive with an activated carbon 106 at these suction nozzle 102 centre bores 105 front ends, after the flue gas that makes cigarette is entered by several through holes 104 of hollow tube 101, filtration via activated carbon 106, just send by suction nozzle 102 places, this activated carbon 106 can filter the soot impurity in the flue gas, but, but do not have the filter efficacy of essence for the nicotine grease that really is detrimental to health.

The purpose of this utility model is to provide a kind of filter tip that can effectively filter the nicotine grease.

The purpose of this utility model is to realize like this.A kind of filter tip, its mainly by a front end can for cigarette plug and its position, stage casing be between the clear area hollow tube, be installed in the filtering bodies in the described hollow tube, and the suction nozzle that is arranged in described hollow tube rear end forms, and it is characterized in that:

Described filtering bodies is a metal stopper rod, establish an annular groove in its front end, sheathed one in order to push against the hollow tube inwall and to block the ring packing ring of its path in this annular groove, establish a front center hole by its center again, and this front center hole depth is gone into after the annular groove, the lever front end sidewall is provided with flue gas ejection through hole, this through hole communicates with described front center hole, a segment distance place establishes a perforation behind flue gas ejection through hole again, this perforation communicates with the back heart hole set in the filtering bodies rear end, and should be communicated with the centre bore of described suction nozzle in heart hole, back.

The end of described filtering bodies can be provided with external screw thread, and end then is provided with one section internal thread before the described suction nozzle centre bore, and the two is spirally connected.

But described hollow tube and suction nozzle fit.

The utility model is owing to adopt above-mentioned design, by special filtering bodies structure, reaches the purpose of effective removal nicotine grease in the physical principle mode, fully avoided commonly using filter tip and only filtered with activated carbon, can not really remove the deficiency of nicotine.Usefulness again after the metal stopper rod of this filter tip is capable of washing, very convenient.

The utility model is described in further detail below in conjunction with accompanying drawing

Fig. 1 is an assembled sectional view of commonly using filter tip

Fig. 2 is the three-dimensional exploded view of the utility model filter tip

Fig. 3 is the stereo appearance figure of the utility model filter tip

Fig. 4 is an assembled sectional view of the present utility model

As Fig. 2, shown in Figure 3, a kind of filter tip 10, it mainly includes a hollow tube 11, a filtering bodies 12 and a suction nozzle 13, wherein:

Described hollow tube 11 front ends are provided with a shrinkage pool 111 and can plug for cigarette, establish a circular hole 112 in shrinkage pool 111 centers and be communicated with the rear end, and the section position is provided with between the clear area among hollow tube 11.

The rear end of described suction nozzle 13 dwindles into flat-shaped crow mouth shape, and its centre bore 131 connects before and after it, and the front end position of suction nozzle 13 dwindles its external diameter, make it can be sheathed on the rear end of hollow tube 11, and reduced outside diameter partly is provided with internal thread 132.

Described filtering bodies 12 is located in the described hollow tube 11, and it is a metal stopper rod, establishes an annular groove 121 in its front end and is used for a sheathed ring packing ring 122, and this ring packing ring 122 just can push against the inwall of hollow tube 11, in order to the path of blocking-up hollow tube 11 front ends.Establish the front center hole 123 of a tool appropriate depth again by its center, make its front center hole 123 penetrate with after its annular groove 121, be provided with the flue gas ejection through hole 124 of a tool smaller aperture due again by the lever front end sidewall, described through hole 124 communicates with described front center hole 123, a segment distance place then is provided with a perforation 125 again after through hole 124, the aperture of this perforation 125 is big and communicate with the back heart hole 126 set in body of rod rear end, in addition screw thread 132 is provided with external screw thread 127 and makes the two be spirally connected mutually within the outside, body of rod rear end is corresponding to suction nozzle 13, and 126 in heart hole is connected with the centre bore 131 of suction nozzle 13 thereafter.

Adopt the filter tip 10 of above structure, as shown in Figure 4, during use cigarette is plugged in the shrinkage pool 111 of hollow tube 11 front ends, the path of the flue gas of cigarette is then for being entered among the hollow tube 11 by circular hole 112 earlier, because the obstruct of the ring packing ring 122 on the filtering bodies 12, then making all flue gases be entered by the front center hole 123 of filtering bodies 12 sends from through hole 124 afterwards, and because the aperture of through hole 124 is less, make a large amount of flue gases after the front center hole 123 of tool larger aperture enters, dwindle suddenly because of the aperture, path, then its speed of sending accelerates and sends in the mode of outside ejection, but be subjected to stopping of hollow tube 11 internal faces, on the inwall side face of nicotine grease that makes in the flue gas attached to place, hollow tube 11 clear areas, can know by the outside and to find out on its inwall side face and have mist a slice, and the cigarette gas that remaining remnant only is a pure gas will continue backward, and enter after filtration heart hole 126 after the body 12 by perforation 125, drawn to suction nozzle 13 centre bores 131; So nicotine grease harmful in the cigarette has been sprayed the attached wall within the hollow tube 11 that adheres to, significantly reduce the danger that material harmful in the cigarette pollutes the human lung, and the filter tip 10 of this creation can be pulled down hollow tube 11 after using a period of time and clean up, and must continue to use.
