Description
Technical field
The present invention relates to a kind of filter, be specifically related to a kind of plug-in type cigarette coke tar filter.
Background technology
Contain harmful substances such as tar in the cigarette, can have a strong impact on health after human body sucks, so people have designed the cigarette coke tar filter and alleviated this harm.Conventional cigarette tar filter generally only adopts a section fibre filter tip to filter, but filter effect is not good.
Based on above-mentioned deficiency, No. 95209314.6 disclosed cigarette coke tar filter of Chinese patent application is a kind of new type of health filter-tip, and it comprises accessories such as wall pipe, adsorbent, filtration film and filtering bodies; The pore internal diameter of wall pipe strengthens from left to right step by step, and the left end of wall pipe stretches into the end in the mouth during for smoking, and the right-hand member of wall pipe is for inserting an end of cigarette, described adsorbent, filters the stage casing that film and filtering bodies are set in turn in the wall pipe from left to right.The tar of above-mentioned health care filter-tip in to a certain extent can filter cigarette, yet, this type of health-care cigarette holder has many deficiencies: (1) smoker must insert cigarette the right-hand member of the tube wall of cigarette holder earlier, left end with tube wall stretches in the mouth again, cause smoker's mouthfeel in smoking process not good, and uncomfortable; (2) relatively heavier, cigarette is inserted into the right-hand member of tube wall, whole length is increased, bring very big inconvenience to smoking; (3) complex structure, manufacturing difficulty and raw-material wasteful cause cost to rise.
Summary of the invention
Technical problem to be solved by this invention is, deficiency at existing cigarette coke tar filter, a kind of plug-in type cigarette coke tar filter is provided, the smoker need not to change original smoking habit, have the smoking mouthfeel good, simple in structure, easy to use, save raw material and advantage such as reduce cost.
Technical scheme provided by the invention is: a kind of plug-in type cigarette coke tar filter is provided, comprise and be used for the filtration of filter cigarette tar, described filtration is provided with the pin that can insert in the cigarette, described filtration comprises filtering bodies and filter cap, forms filter chamber between the bottom of described filter cap and described filtering bodies.
Described filter cap is socketed on the described filtering bodies, and the internal face of described filter chamber is provided with concaveconvex structure.
Described pin and described filtering bodies are one-body molded, and described filtering bodies and described pin are cylindric and coaxial.
In above-mentioned plug-in type cigarette coke tar filter, described filtering bodies is provided with axial filtering holes.
In above-mentioned plug-in type cigarette coke tar filter, the bottom of described filter cap is provided with smoking-hole.
In above-mentioned plug-in type cigarette coke tar filter, described smoking-hole is provided with the flange that extends internally, and leaves the gap between described flange and the described filtering bodies.
In above-mentioned plug-in type cigarette coke tar filter, the inwall of described filter cap is provided with holddown groove, and described filtering bodies is arranged in the described holddown groove.
In above-mentioned plug-in type cigarette coke tar filter, the end of described pin is provided with spur, and the diameter of described filtration is less than the diameter of cigarette.
In above-mentioned plug-in type cigarette coke tar filter, the diameter of described filtration equals the diameter of cigarette.
In above-mentioned plug-in type cigarette coke tar filter, the diameter of the internal face of described filter cap increases from left to right gradually, interference engagement between described filtering bodies and the described filter cap.
Owing to adopt technique scheme, the filtering bodies of plug-in type cigarette coke tar filter of the present invention is to combine by mode and cigarette that pin inserts, thereby the diameter of filtering bodies can be less than or equal to the diameter of cigarette, the smoker can directly put into mouth with cigarette, need not to change original smoking habit, have the smoking mouthfeel good, simple in structure, easy to use, save raw material and advantage such as reduce cost.

Fig. 3 is the axial cutaway view of plug-in type cigarette coke tar filter first embodiment of the present invention.
The schematic diagram that Fig. 4 combines with cigarette for plug-in type cigarette coke tar filter first embodiment of the present invention.
Fig. 5 is the axial cutaway view of plug-in type cigarette coke tar filter second embodiment of the present invention.
The specific embodiment
Fig. 1 to Fig. 3 shows first embodiment of plug-in type cigarette coke tar filter of the present invention, it comprises circular filtration 1 and combines the pin 2 that also can be plugged in the cigarette with described filtration 1 that described filtration 1 is made of filtering bodies 10 and the filter cap 12 that is socketed on the described filtering bodies 10.
Described filtering bodies 10 is cylindric, evenly be laid with four axial filtering holes 101 on it, but the quantity of described filtering holes 101 is not limited to four.Described pin 2 also is cylindric, and it is arranged on described filtering bodies 10 central parts and coaxial with described filtering bodies 10, and described filtering bodies 10 is one-body molded with described pin 2.The end of described pin 2 is provided with spur 21, and described spur 21 makes described pin 2 easier being inserted in the cigarette.
Described filter cap 12 is cylindric, and it is socketed on the described filtering bodies 10, forms filter chamber 122 between the bottom 121 of described filtering bodies 10 and described filter cap 12.The internal face of described filter cap 12 offers the holddown groove 123 that is used for fixing described filtering bodies 10.During assembling, described filtering bodies 10 can be pushed in described filter cap 12 and push, in being fastened on described holddown groove 123 till.Described filter chamber 122 can hold liquid cigarette tar, and inner wall surface thereof can be adsorbed the tar in the cigarette smoke simultaneously.For strengthening the tar adsorption effect of described filter chamber 122, inner wall surface thereof can be made into concaveconvex structure, to increase the contact area of internal face and flue gas.The central part of the bottom 121 of described filter cap 12 is provided with and can makes filtered smoke gas enter smoking-hole 124 in smoker's mouth, and described smoking-hole 124 extends in described filter chamber 122 flange 125.Described flange 125 can prevent that on the one hand the tar liquid in the described filter chamber 122 is inhaled in smoker's the mouth, can increase the contact area of the internal face and the flue gas of described filter chamber 122 on the other hand, improve the tar adsorption effect of the internal face of described filter chamber 122.Leave the gap between described flange 125 and the described filtering bodies 10, so that the flue gas in the described filter chamber 122 enters smoking-hole 124.
The course of work of plug-in type cigarette coke tar filter of the present invention is as follows:
Please refer to Fig. 4, plug-in type cigarette coke tar filter of the present invention in use, filtration 1 axially is plugged in the fiber filter tip 32 of cigarette 3 by pin 2, the diameter of described filtration 1 is slightly smaller than or equals the diameter of described fiber filter tip 32, the smoker just can directly put into mouth with cigarette like this, need not to change original smoking habit.During smoking, flue gas at first is delivered to fiber filter tip 32 from the smoke 30 of cigarette 3, enters filtration 1 after filtering through described dimensional filter mouth 32; Enter filter chamber 122 through filtering holes 101 again, the tar in the flue gas is attracted to the internal face of described filter chamber 122, forms tar liquid; At last, enter through described smoking-hole 124 in smoker's the mouth, the content of harmful such as flue gas tar that enter into smoker's mouth are subtracted greatly.
Fig. 4 shows second embodiment of plug-in type cigarette coke tar filter of the present invention, the structure of itself and first embodiment is basic identical, difference is, the diameter of the internal face 421 of the filter cap 42 of filtration 4 increases from left to right gradually, and the mode and the described filter cap 42 that filter body 40 and be by interference engagement combine.
