Abstract

The utility model relates to a cigarette tip capable of effectively eliminating toxic and harmful substances, which are absorbed by tobacco from fertilizers, pesticides and soil during planting. The utility model comprises filter tip, activated carbon fiber felt, and tobacco. The utility model is characterized in the activated carbon fiber felt arranged in middle position and in shape of flat block. The utility model has the following beneficial effects: 1. the activated carbon fiber felt can actively and effectively adsorb toxic and harmful particles in smoke, and reduce harm to human body; 2. the filter tip is improved by only adding an activated carbon fiber felt in middle part of filter tip, so it has simple structure and easy manufacture.

Description

The efficient cigarette harmful matter filter tip of removing

Technical field

The utility model is to adopt novel high absorption activated carbon fiber material, cigarette to present production is efficiently adsorbed, poisonous and harmful substance in various chemical fertilizer, agricultural chemicals and the soil that absorbs in the time of can effectively removing tobacco growing reaches the physical impairment of minimizing to the smoker.

Background technology

The cigarette that at present domestic all cigarette factories produce is removed and is installed additional outside the common filter tip, has only extremely to add bead loading shape active carbon in the middle of other filter tip, does not also have a family that the high adsorption active carbon fibrous material is housed.

Because NACF has very big specific area (1000m ²-1800m ²/ g), very big pore volume and certain pore-size distribution (3 -20  left and right sides micropore accounts for 83.9%).Just because of it has this architectural characteristic, make it bigger tens times than charcoal absorption amount of using in now " breathing mask ", germ, microorganism, thousands of kinds of poisonous and harmful substances and gas, organic compound, odorant etc. there are good adsorption capacity.The 2nd, high two to three orders of magnitude of rate of adsorption specific activity charcoal (thousands of times).The 3rd, desorption is fast, shines as the sun, and dry processing of hot-air gets final product desorption, and behind over thousands of suction, the desorption, its absorption property is constant, and is reusable, reduces cost.The 4th, heat-resisting, acidproof, alkaline-resisting, chemical stability is good, non-secondary pollution.

We are applied in this high-tech new material on the cigarette filter, just can improve filter efficiency greatly.Over 5 years, good from the reaction of experimenter's direct feel, the cigarette that sensation is inhaled stimulates the throat and reduces, free from extraneous odour, and the more important thing is does not have phlegm, and it is continuous that the cigarette that sensation is inhaled becomes.

Summary of the invention

Existing the cigarette filter filter efficiency is not good designs in order to solve for the utility model.Install the novel filter material NACF additional in former filter-tipped centre in the hope of improving the filter efficiency of cigarette filter.

The utility model is that the technical scheme that addresses the above problem proposition is;

Consult Fig. 1: between cigarette filter 1 and pipe tobacco 3, vacate the 1.5mm-2mm space and install NACF felt 2 additional.Consult Fig. 2:, install NACF felt 2 therebetween additional with being divided into two in the middle of the cigarette filter 1.Consult Fig. 3: the cigarette filter fiber with after NACF evenly mixes, is made novel filter tip 4 and is installed on the cigarette.

Characteristics of the present utility model are: changing in the past, cigarette filter only filters for barrier type, after having installed NACF additional, because the long open capillary hole (3 -20  capillary hole accounts for 83.9%) in a large amount of Shan is arranged on the charcoal fiber, when flue gas by the time will produce the capillary condensation phenomenon, form negative pressure in the hole, by air-flow with various chemical fertilizer, agricultural chemicals and various poisonous and harmful substance molecule will be inhaled into hole and can't enter human body.Change simple barrier type and filter, becoming initiatively, absorbent-type filters.

Description of drawings

Fig. 1, between cigarette filter and pipe tobacco, install NACF felt structure chart additional for the utility model.

Fig. 2, between being divided into two, cigarette filter installs NACF felt structure chart additional for the utility model.

Fig. 3, make novel filter tip 4 structure charts at the even mixed active charcoal of cigarette filter fiber fiber for the utility model.A is the integral filter mouth, and B is the segmentation filter tip.

The specific embodiment

Further specify embodiments of the invention below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3.

Consult Fig. 1: cigarette filter 1, NACF felt 2, pipe tobacco 3 is characterized in that installing additional NACF felt 2 between cigarette filter and pipe tobacco.Consult Fig. 2: cigarette filter 1, NACF felt 2, pipe tobacco 3 is characterized in that cigarette filter is installed additional NACF felt 2 in the middle of being divided into two.Consult Fig. 3 A: cigarette filter fiber and NACF evenly are mixed and made into filter tip 4, tobacco 3.Consult Fig. 3 B: cigarette filter 1, cigarette filter fiber and NACF evenly are mixed and made into filter tip 4, tobacco 3, it is characterized in that cigarette filter fiber and NACF evenly are mixed and made into filter tip 4 and are contained on the cigarette.

Claims

A kind of efficient removing cigarette harmful matter filter tip that can remove the poisonous and harmful substance in various chemical fertilizer, agricultural chemicals and the soil that absorbs in the tobacco planting, include cigarette filter (1), NACF felt (2), pipe tobacco (3), or filter fiber and NACF evenly be mixed and made into filter tip (4), it is characterized in that being provided with in the middle of filter tip NACF.
