Description
Technical field
The present invention relates to a kind of filter tip, especially a kind of cigarette filter.
Background technology
As everyone knows, smoking brings very big harm to smoker's healthy meeting, and when the cigarette that sucks was more and more, some position of health such as lung, respiratory tract etc. can produce pathology, thereby caused the recurrence of various diseases, and severe patient can be carcinogenic.Some smoker uses tobacco pipe to increase the distance that flue gas is flowed through when smoking cigarette, high boiling material most of condensation sedimentation in tobacco pipe in the flue gas, so tobacco pipe has played the effect of reducing tar and reducing harm.Though tobacco pipe can reducing tar and reducing harm, in actual use, tobacco pipe is not easy to carry, and along with the long-time use of tobacco pipe, must regularly clean tobacco pipe simultaneously, has brought trouble to the smoker, and therefore present most of smoker does not use pipe smoker.
Summary of the invention
The objective of the invention is to propose a kind of cigarette filter of new structure, motion mode and motion path that it has changed flue gas have prolonged the distance that flue gas is flowed through, and make the circulation of flue gas more unobstructed, have suitably reduced the infringement of cigarette to health of smokers.
The present invention is that the technical scheme below adopting realizes: a kind of cigarette filter comprises filter rod, wherein; Filter rod comprises the stub that lays respectively at the filter rod two ends, and stub is all cylindrical, and its outer surface is level and smooth shape; Connect through pitman between two stubs, be provided with continuous groove along the annular outer surface of pitman, this filter rod is formed by connecting stub that is positioned at two ends and pitman; The stub of filter rod one end is provided with centre bore; Bottom, the hole of centre bore is provided with at least one connecting hole, is communicated with through connecting hole between the groove of centre bore and pitman, and centre bore is of a size of 2-5 times of connecting hole size; The stub of the filter rod other end is provided with the air guide groove, and the degree of depth of air guide groove is not less than the degree of depth of the continuous groove of pitman.
Among the present invention, the groove of said pitman annular outer surface can be continuous screw-type groove, connects through the screw-type pitman between two stubs, and filter rod is formed by connecting screw-type pitman and the stub that is positioned at the pitman two ends.Described screw-type groove can be single thread type groove, two screw-type groove, three screw-type grooves or four screw-type grooves.
The pitch of screw thread is 1-5mm on the said screw-type pitman.Concrete pitch generally will be confirmed according to the factors such as tightness degree between type, packaging material and the filter rod of the material of filter rod, packaging material.
The continuous groove of said pitman annular outer surface also can be the continuous groove of " Z " type, the continuous groove of " H " shape or the continuous groove of " S " type that axially is provided with along pitman, i.e. Z type, H type or the S type all over design of groove shapes for axially being formed by connecting along pitman.At this moment, above-mentioned continuous groove axially is provided with one at least along pitman, and the continuous groove of each bar is along the spaced radial setting of pitman.
The filter rod that described filter rod and at least one section are processed by acetate fiber, tobacco powder, paper pulp fiber, acid fiber or polypropylene fibre is compound, forms composite filter tip, like binary composite filter tip, ternary composite filter tip or polynary composite filter tip.
The diameter of said centre bore is 5-10mm, and the diameter of connecting hole is 1-5mm; The length of stub is 5-10mm, and the length of pitman is 5-50mm.
The shape of said centre bore and connecting hole can be circular, square, rhombus or other shapes.
Beneficial effect of the present invention: through the structure of existing filter rod is improved; At first; The pitman two ends that are provided with annular groove at outer surface are provided with ganoid stub; Can prevent between the many pitmans meshingly each other, filter rod can successfully drop out from material-falling hopper in the filter rod forming process; The second, centre bore and the connecting hole that centre bore is connected with the pitman groove are set therein, in the stub of an end after the flue gas connecting hole less along diameter flows into the relatively large centre bore of diameter; Changed the motion mode of flue gas; Make the velocity of liquid assets moment reduction of flue gas, the macromolecular substances of being convenient in the flue gas precipitates in centre bore, makes the mouthfeel of flue gas better; Fragrance is more mellow, has played the effect of reducing tar and reducing harm simultaneously; The 3rd, when filter rod is carried out the segmentation cutting, can cut apart in the position of stub, prevent that packaging material from caving in, packaging material can not coat the end face of filter rod, have guaranteed that the filter rod ventilation is smooth and easy; The 4th, have the distance that the pitman of continuous groove can prolong smoke be flowed through, reduce the tar content in the cigarette, suitably reduce the infringement of cigarette to health of smokers, make the flue gas of cigarette softer simultaneously, fragrance is mellow, and pleasant impression is more comfortable; The 5th, because filter rod cuts in stub punishment, the end face of therefore cutting apart the back filter rod is provided with air slot, and air slot can make the filter rod ventilation more smooth and easy, and the manufacturing moulding that the air guide groove also is convenient to filter rod is set.
