Al in the second step 2 O 3 The ratio of the powder to the adhesive is 4: 1;
the adhesive in the second step is specifically silicone resin.
The adsorption solution in the fourth step is specifically anthracite or activated carbon.
Specifically, in the embodiment of the invention, the provided spiral porous filter device based on the electronic cigarette, namely the spiral porous electronic cigarette filter tip comprises a blade 1 with a spiral circular tube-shaped outer ring, a circular tube inner filter medium layer 2, a polygonal-hole filter layer and a cigarette holder body 4, wherein the spiral blade 1 surrounds the cigarette holder body 4, part of smoke can be allowed to flow along the spiral blade, the circular tube inner filter medium layer 2 is arranged above the polygonal-hole filter layer, and part of smoke reaches the polygonal-hole filter layer through the filter medium layer 2 and then flows out of the filter layer.
As shown in the attached drawing, the central part of the cigarette holder is separated by the filter medium layer 2, the flow velocity of smoke is slow, so that partial gas can flow out from the outer ring with relatively fast flow velocity, the surface of the spiral blade 1 on the outer ring of the cigarette holder body 4 is uneven, the filter medium material with stronger adsorption capacity is attached, and the spiral flue structure enables the stroke of the smoke to be prolonged, the reaction time with the filter medium to be prolonged, and the filtering effect to be better.
That is to say, the electronic cigarette filter tip of this scheme mainly includes outside spiral shell, filter medium layer 2, polygon filter baffle, cigarette holder body 4, outside spiral shell around on cigarette holder body 4, on outside spiral shell, scribble the corresponding filter medium, polygon filter baffle be in cigarette holder central part. The filter medium layer 2 is arranged above the polygonal filter partition plate. Adopt the spiral electron cigarette filter tip of this patent, the flue gas circulates simultaneously from inside and outside two parts, has guaranteed that the cigarette hinders in reasonable interval, has also increaseed the stroke of flue gas simultaneously, makes it can fully react with filter media, has better filter effect. The inner diameter of the cigarette holder body 4 is 3.7 mm; the outer diameter was 4 mm.
Preferably, in order to obtain a better filtering effect, the spiral fan blade is required to be made into an uneven surface and attached with a high-adsorbability filtering medium material, so that the contact time and the contact area of the gas and the reaction medium are increased, and the effect of filtering the flue gas is achieved. However, the spiral fan blade of the cigarette holder cannot be too long, otherwise the suction resistance can be greatly increased, and the using taste is reduced.
The manufacturing process of the scheme is as follows:
according to the spiral porous electronic cigarette filter tip, a powder bed melting process (Power bed fusion) is selected, a selective laser melting technology (SLM) is adopted for printing layer by layer, and the spiral porous electronic cigarette filter tip is high in finished product quality and good in surface quality. The specific parameters are as follows:
TABLE 1 PBF Experimental data sheet
The filter element printed by the experimental data has good surface quality and high finished product precision, can print a plurality of filter element components simultaneously, and has more stable manufacturing performance. Because the SLM adopts a high-precision execution control mechanism, high-quality printing of a more complex shape structure can be realized, the finished product has good surface quality, further processing is not needed, and the cost of manufacturing manpower and time is saved.
The surface of the filter element of the finished product of the SLM process has a certain porosity, so that the post-treatment is convenient, the finished component is placed in an adsorption solution (anthracite, activated carbon and the like) and stands for a period of time, partial adsorption solution substances can fill the pores on the surface of the filter element component through a physical diffusion mechanism, and the finished component filter element can enter the subsequent test through methods such as drying treatment and the like.
The working principle of the electronic filter tip is as follows: mainly through the helical shape flabellum, to a certain extent, the flow path of extension flue gas through surface roughening treatment, can increase the area of contact of flue gas and filter medium simultaneously to at the filter medium of the strong adsorbability of surface adhesion, it is more excellent to have guaranteed that the filter effect of flue gas is.
By adopting the novel spiral porous electronic cigarette filter tip, for supplementary explanation of the actual service effect of adopting the novel structure, several groups of examples are selected for supplementary explanation of the parameters of the suction resistance, the filtering effect and the like of several groups of experiments:
table one experimental group
1. Comparison of resistance to draw
The resistance to draw is an important parameter of the use experience of the electronic cigarette, and after a cigarette resistance instrument device (figure 4) simulates the smoking action of a person on a filter to suck air with a fixed flow rate (standard is 17.5 ml/s), a certain vacuum pressure is generated at the suction end of the filter, and the pressure is the resistance to draw. The difference of experience brought by the filter tip can be reflected by the comparison of the suction resistance.
Put cigarette smoking resistance device respectively in the mouth of a cigarette position, read the smoking resistance value of different samples, through the contrast to smoking resistance data on the different test samples, explain different filtration to the hindrance effect of flue gas, indirect measurement filter tip gives other people brings the difference of experience sense.
Figure 5 is a graph of actual cigarette test data. As is obvious from the figure, compared with the most common paper cigarette, the cigarette has smaller suction resistance, and can bring better use experience to people. Because the spiral blade 1 is additionally arranged outside the filter element of the electronic cigarette, the reaction time of smoke and a filter medium is prolonged, the filter effect is ensured by enhanced filtration, the smoke can flow out more, and the experience of a user is improved.
2. Filtering effect of nicotine
Nicotine (also called Nicotine) is an organic compound, has a chemical formula of C10H14N2, is highly toxic, is an alkaloid existing in solanaceae plants (solanum), is also an important component of tobacco, is also a representative of N-choline receptor agonist, has effects on N1 and N2 receptors and central nervous system, and has no clinical application value.
Nicotine can cause addiction or dependence, and repeated use of nicotine also increases heart rate and raises blood pressure and reduces appetite. Large doses of nicotine can cause vomiting and nausea, and in severe cases, death. Tobacco typically contains nicotine. Electronic cigarettes also contain nicotine, a harmful substance of traditional tobacco.
