CN203555156U - Filtering cigarette holder with long service lifetime - Google Patents

Abstract

The utility model relates to a filtering cigarette holder with the long service lifetime. The filtering cigarette holder comprises a cigarette inlet pipe provided with a smoke channel. The front end and the rear end of the cigarette inlet pipe are respectively provided with a cigarette inserting port and a cigarette outlet port. The cigarette inserting port and the cigarette outlet port are communicated with the smoke channel. A filtering member is arranged on the smoke channel. The rear portion of the cigarette inlet pipe is connected with a hollow cigarette outlet pipe. A small pipe is inserted into a hollow portion from the rear end of the cigarette outlet pipe and a deposition chamber which is communicated with the cigarette outlet port is enclosed by the small pipe and the inner wall of the cigarette outlet pipe. A smoking port is formed at the rear end of the small pipe. When smoke is filtered by the filtering member, tar inside is attached to the inner wall of the cigarette outlet pipe and is condensed to be in the liquid state and then flows along the inner wall of the cigarette outlet pipe to the deposition chamber, and smoke after being de-oiled is discharged from the smoking port. The filtering cigarette holder with the long service lifetime has following beneficial effects: due to the fact that the deposition chamber is arranged, accommodating space of tar after being condensed is increased and service and cleaning periods of the cigarette holder are prolonged; and the filtering cigarette holder can be applicable to filtering cigarette smoke.

Description

The filter-tip that life cycle is long

Technical field

The specific embodiment

The first embodiment as shown in Figure 1-Figure 3, the filter-tip that life cycle is long, comprises the smoke-intake pipe 1 that is provided with exhaust gases passes, this smoke-intake pipe 1 is comprised of the tube connector 13 of inserting smoke pipe 12, the second filter cap 5 and hollow.Wherein, the slotting smoke pipe 12 of hollow is positioned at front portion, and its front end is provided with the slotting mouth 11 of placing cigarette.Insert smoke pipe 12 and be provided with from front to back one-level double-screw bolt 121, secondary double-screw bolt 122 and the three grades of double-screw bolts 123 that diameter reduces successively.One-level double-screw bolt 121 is mainly used for being connected with the outer tube of smoke-intake pipe 1.The tail end of three utmost point double-screw bolts 123 is connected with the first filter cap 4, the first filter caps 4 and is provided with some the first filter openings 41, and these first filter openings 41 are communicated with slotting mouth 11 by inserting the hollow space of smoke pipe 12.

The second filter cap 5 is threaded on three utmost point double-screw bolts 123, and is just sheathed on the periphery of the first filter cap 4, and has certain gap with the outer wall of the first filter cap 4, and some the second filter openings 51 that make to be opened in the second filter cap 5 are communicated with the first filter opening 41.

Tube connector 13 screw threads are arranged on secondary double-screw bolt 122, tube connector 13 middle parts are external thread structure, and the external diameter of this external thread structure is identical with the external diameter of secondary double-screw bolt 122, the tail end of above-mentioned external thread structure is provided with the 3rd filter cap 6, the 3rd filter cap 6 is provided with the 3rd filter opening 61 of some connection tube connector 13 cavitys, and the 3rd filter opening 61 is as the outlet flue of smoke-intake pipe 1.In the cavity of the first filter cap 4, second filter cap 5 these tube connectors 13 of insertion, the 3rd filter opening 61 is communicated with the second filter opening 51.Therefore, the hollow space of hollow space, the second filter cap 5 and the tube connector 13 of slotting smoke pipe 12 has formed by inserting the exhaust gases passes of mouth 11 to outlet flue.

The pipe 2 of the hollow that is threaded on the external thread structure of tube connector 13 and pipe 2 are positioned at the tail end of tube connector 13.Pipe 2 has smooth inwall, and the 3rd filter cap 6 is inserted the hollow space of pipe 2.By above-mentioned structure, can be drawn, flue gas flows out and carries out the filtering of first tar in attached wall and the condensation for the first time of the second filter cap 5 inwalls from the first filter opening 41, flue gas flows out and carries out the filtering of second tar in attached wall and the condensation for the second time of tube connector 13 inwalls from the second filter opening 51 afterwards, from the 3rd filter opening 61, flow out again and carry out the tar filtering of San road in attached wall and the condensation for the third time of pipe 2 inwalls, therefore this structure can filter out tar contained in pipe tobacco to greatest extent, reduces as far as possible the damage to human body.

The tubule 3 that the tail end of pipe 2 is provided with end cap 22, one hollows inserts pipe 2 hollow spaces and surrounds with inwall, the end cap 22 of pipe 2 deposit cavity 21 that is communicated with outlet flue from end cap 22, and the tail end of tubule 3 forms smoking port.Deposit cavity 21 provides the accommodation space of the tar of pipe 2 inwall condensations, before the length of inserting lower than tubule 3 at the tar depositing, smoker all can not suck liquid tar, has greatly improved life cycle and the cleaning frequency of cigarette holder, to smoker, provides convenience.According to test, owing to being provided with deposit cavity 21, the cigarette holder in the present embodiment is compared than the cigarette holder in conventional art, and before must cleaning, the quantity of smoking has improved at least one times.

Preferably, the length of the insertion portion of tubule 3 should be lower than 5mm, and insertion portion length is longer, and the volume of deposit cavity 21 is larger, is more conducive to accommodating tar.

Preferably, tubule 3 is threaded with pipe 2, and the tail end of tubule 3 is connected to the part 31 of outwarding winding, and facilitates tubule 3 dismountings, and after tubule 3 unloads, the hole that part tar can form from end cap 22, flows out.

In the second embodiment as Figure 4-Figure 6,1 of smoke-intake pipe is comprised of slotting smoke pipe 12 and the second filter cap 5, and omitted the tube connector 13 in the first embodiment, pipe 2 is directly threaded on secondary double-screw bolt 122, although reduced like this structure of filtering together, but the structure of saving is conducive to reducing of cigarette holder length, more convenient user carries.

The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
