Description

A kind of filter-tip

Technical field

The utility model relates to a kind of smoking equipment, particularly relates to a kind of filter-tip.

Background technology

We know that the work principle of filter of filter-tip has following several aspect:

1, physical barrier is filtered: promptly by the cotton circulation level that increases flue gas of environmental protection, make the tar of flue gas and solid shape material attached on the filter cotton, the enhancing filter effect.

2, air ratio flows through filter: adopt the control of speed air flow to reduce tar content, air speed through micropore the time can be accelerated, but individual cavity is arranged in the middle of the cigarette holder, flue gas just here can slow down, and outlet also is a micropore, and flue gas can be done brief stay in cavity, tar can be attached on the filter, flue dust in the flue gas also can drop in the cavity in deceleration and tar forms mixture, and a large amount of like this harmful substances is just dammed in cavity.

3, magnetite filters: the magnetic field of magnetite can make flue gas flow through out-of-date direction according to field of magnetic forece, and magnetite itself is cold, is that tar and flue dust reach the effect of damming.

4, also have other chemical particles can reach the effect of filtration at present

The filter-tip of making according to above-mentioned principle generally is divided into promptly abandons type, directly abandons well in that smoking is a certain amount of; Change core pattern, the filtration system in the middle of this cigarette holder is to place in addition, can easily take out, and directly takes out in a certain amount of back of smoking, and changing to new filter core can directly use; Cleaning-type, promptly the filtration fraction of cigarette holder generally can freely be extracted, and can continue again after wiping away or washing to use by putting on the skin, and can repeatedly clean use.

Present existing filter-tip mostly is and promptly abandons type and cleaning-type, primary structure comprises cylindrical tobacco rod shell and the middle tobacco rod mouth composition that has the exhanst gas outlet through hole, the tobacco rod shell has cylindrical cigarette for one section and inserts interface, the other end has cylindrical adsorption chamber, cigarette is inserted between interface and the adsorption chamber and is connected by smoke intaking hole, through being threaded, filling in the adsorption chamber and filter adsorbing medium between tobacco rod shell and the tobacco rod mouth.The filter-tip of this kind structure belongs to promptly abandons type or cleaning-type, as promptly abandoning the type cigarette holder, can cause too much waste, increase consumer's smoking cost, and as the cleaning-type cigarette holder, can bring inconvenience to the user again, in addition, the filtration, purification effect of the filter-tip of this kind structure is not too desirable.In the patent No. is disclosed in 200720106506.6 " a kind of cigarette holder ", adsorption chamber is divided into two cavitys, a cavity is an adsorption chamber, filler particles activity of bamboo charcoal charcoal, another cavity is the filter chamber, fills doughnut activity of bamboo charcoal charcoal, though improved the filtration, purification effect, promptly abandon type or cleaning-type but structure type also belongs to, existing problem still is not resolved.

The utility model content

The utility model is at the deficiencies in the prior art; a kind of filter-tip is provided; both had the clean-up effect height; advantage of simple structure; can change filter medium at any time easily again; directly take out in a certain amount of back of smoking; changing to new filter medium can directly use; technical solution adopted in the utility model is as follows; the utility model comprises tobacco rod and tobacco rod mouth composition; tobacco rod is a hollow shape; be provided with catch therebetween; catch is provided with smoke ventilator; one end of catch is a cigarette interface; the other end is a cavity; its port is provided with connecting thread; after being threaded, form an adsorption chamber between tobacco rod and the tobacco rod mouth; be filled with the filtration adsorbing medium in this adsorption chamber; it is characterized in that in the adsorption chamber it being integral filter core; this integral filter core comprises a tubular shell that has tapering, is provided with excessive step in the middle of the housing, and housing is divided into two cone cavity of size; wherein be filled with ceramic element in the conelet body cavity; in the big cone cavity is fruit stone class granular activated carbon, and the termination of conelet body cavity is relative with the cigarette hole of tobacco rod mouth, and big cone cavity one end is provided with active carbon gland and middle rubber ring with holes; the gland periphery is provided with groove vertically; form flue between groove and the filter core housing, an end of gland is an alignment pin, and the other end is a groove; the groove limit is provided with aperture; communicate with flue, rubber ring covers on groove, and the hole on it is relative with smoke ventilator on the catch.

Mechanism of the present utility model is as follows:

During use, cigarette is inserted in the cigarette interface place and lights, during smoking, flue gas enters in the groove of gland through the cigarette hole of tobacco rod mouth, the hole in the middle of the rubber ring, aperture on the groove limit, flue enter in the big cone cavity again, are filtering laggard entrance cavity by ceramic element after charcoal absorption.

Compared with prior art, essence has the following advantages with novel:

1, this has adopted in novel fruit stone class granular activated carbon and ceramic element as filtering adsorbing medium, thereby makes filter effect be greatly improved, and good purification removes that the effect of pernicious gas significantly improves in the tobacco.

2, this novel middle integral filter core structure that adopts can be changed filter medium at any time easily, has promptly avoided promptly abandoning the type cigarette holder, the smoking cost of waste that causes and increase, the inconvenience of having avoided the cleaning-type cigarette holder to bring again to the user, and simple in structure, easy to use.
