[0002] As the atomization industry continues to develop, the use of porous atomization cores has gradually become a part of people's lives. However, due to the different fields of use and the diversity of atomization liquids, general atomization cores cannot guarantee long-term atomization, and the occurrence of bacteria due to the expiration of atomization liquids will also greatly shorten the service life of the atomizer. This is especially true in the industries of electronic cigarette atomization and medical atomization. Moreover, with people's relentless pursuit of health ideals, it seems that it is particularly important to research healthy and environmentally friendly atomization cores.

[0003] Currently, one of the solutions is to choose environmentally friendly materials and replace the atomizing core periodically, but this not only greatly limits the scope of use of the atomizing core, but also increases the usage cost.

[0021] The present invention will be further described below in combination with the drawings and examples. [Brief description of the drawings]

[0023] In order to make the technical features, objects and effects of the present invention more clearly understandable, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0024] The porous atomizing core capable of releasing negative ions in the present invention contains, as raw materials and their mass parts, 50 to 90 parts of tourmaline, 0 to 30 parts of ceramic powder, 10 to 30 parts of a pore-forming agent, 0 to 30 parts of a combustion improver, 0 to 35 parts of paraffin, and 0 to 2 parts of a surfactant.

[0025] Tourmaline is a silicate mineral with a ring structure, and its special crystal structure has a permanent spontaneous polarization effect, which gives it pyroelectric, piezoelectric, infrared radiation, negative oxygen ion emission, and bioelectric properties. The far infrared rays generated by tourmaline can kill bacteria in the nebulizer liquid, promote blood circulation, and promote metabolism. In addition, the negative ions generated by tourmaline can ionize the nebulizer liquid to make it weakly alkaline, which further contributes to physical and mental health. In addition, the microcurrent generated by tourmaline is the same as the weak biocurrent in the human body, and can cause bioelectric phenomena in the human body.

[0026] Preferably, the tourmaline has a particle size of 100 to 1500 mesh.

[0027] Furthermore, in order to improve the emission performance of negative ions and far infrared rays in tourmaline, the tourmaline is modified to form a primary modified tourmaline or a secondary modified tourmaline.

[0028] Primary modified tourmaline is obtained by the following modification method. That is, 100 parts of tourmaline are added to an appropriate amount of cerium nitrate hydrate solution (cerium nitrate hydrate solution) with a mass fraction of 1 to 10%, mixed, and placed in a chromatography column for circulation and overloading for 2 to 5 hours. Next, the suspension that has completed overloading is stirred by magnetic force, and ammonia water with a mass fraction of 5 to 10% is slowly dropped. Then, when the pH value reaches 10, the dropping is stopped, pure water is added, and the mixture is stirred and washed several times (for example, twice), and the supernatant liquid is removed. This is dried in an oven at 70 to 90 ° C, and then placed in a sintering furnace and calcined at 500 to 600 ° C for 4 to 6 hours. The product obtained after calcination is primary modified tourmaline.

[0029] The above primary modified tourmaline can be modified again to obtain secondary modified tourmaline. The modification method is as follows: take 100 parts of primary modified tourmaline and 200 parts of anhydrous ethanol, mix them, and then Magnetic stirringThen, add 60 parts of butyl titanate and stir for 2-3 hours. After stirring, remove the supernatant liquid. Dry it in an oven at 70-90℃, then place it in a sintering furnace and calcinate it at 450-550℃ for 3-4 hours. The product obtained after calcination is the secondary modified tourmaline.

[0030] The SEM image of the secondary modified tourmaline is shown in Figure 1. From Figure 1, we can see that the surface of the tourmaline after the secondary modification is smooth. After the tourmaline is bonded with TiO2, many fine particles appear on the surface, which means that the modification result is favorable.

[0031] During the first modification, Ce (cerium) has two types of variable valence. Ce 3+ is Ce under light irradiation conditions. 4+ During the process of the change, electron-hole recombination occurs. However, due to the presence of electrostatic fields at both ends of tourmaline, the electrons involved in the recombination move due to the action of the electric field, reducing the probability of electron-hole recombination. As a result, a large amount of energy is stored on the surface of the tourmaline / Ce composite material, increasing the amount of negative oxygen ions released. In addition, during the secondary modification, the titanium dioxide produced has a photocatalytic effect, which not only improves the effect of the primary modification, but also promotes the emission of negative ions and far infrared rays from tourmaline when the electrons on the TiO2 surface absorb sufficient energy and leave when irradiated with light or ultraviolet rays.

[0032] The ceramic powder contains at least one of negative ion powder, far infrared powder, attapulgite, feldspar, and zeolite, and has a particle size of 100 to 1500 mesh. The feldspar is potassium feldspar and / or albite.

[0033] The combustion improver is at least one of metal oxide and glass powder, and has a particle size of 325 to 2000 mesh and a melting start temperature of 300 to 500° C. The metal oxide can be at least one of magnesium oxide, titanium dioxide, niobium oxide, etc.

[0034] The pore-forming agent is at least one of wheat flour, PS microspheres, C powder (carbon powder) and rice husk powder, and has a particle size of 80 to 1000 mesh.

[0035] Paraffin is semi-refined or refined paraffin, and has a melting point of 40 to 100°C.

[0036] The surfactant is at least one of sorbitan fatty acid ester (Span), polysorbate (Tween), stearic acid, and oleic acid.

[0037] The method for manufacturing a porous atomizing core capable of releasing negative ions in the present invention includes the following steps.

[0038] S1: Mix the raw materials according to the weight parts and press to form a base material.

[0039] As for the press molding, hot die casting may be used, or dry press molding may be used.

[0040] Furthermore, in the case of hot die casting, the content of the combustion improver in the raw material is preferably 10 to 30 parts, the content of the paraffin is preferably 15 to 35 parts, and the content of the surfactant is preferably 0.05 to 2 parts.

[0041] In the case of dry press molding, it is not necessary to add a combustion improver, paraffin, or surfactant to the raw material.

[0042] S2: The green body is placed in a sintering furnace, and the temperature is increased to 600-800°C at a heating rate of 1-10°C / min to sinter it, thereby obtaining a porous atomized core by a single sintering method.

[0043] As can be understood, the manufacturing method of the porous atomizing core capable of releasing negative ions in the present invention is not limited to the above-mentioned hot die casting or dry pressing, and any other methods for molding and manufacturing the atomizing core can be used.

[0044] The SEM image of the porous atomizing core capable of releasing negative ions in the present invention is shown in Figure 2. It can be seen from the figure that the atomizing core has many voids and the voids are uniform. The uniform voids can fully guarantee the function and effect of tourmaline and can improve the atomizing effect.

[0045] The present invention will now be further described with reference to specific examples.

[0046] Example 1 Each ingredient mass The parts were 80 parts of unmodified tourmaline, 20 parts of glass powder, 20 parts of wheat flour, 20 parts of paraffin, and 0.5 parts of oleic acid. After mixing the above raw materials, they were hot-die cast and sintered once at 600-800°C to form a porous atomizing core.

[0047] Example 2 The same procedure was followed as in Example 1, except that the tourmaline was changed to a primary modified tourmaline.

[0048] Example 3 The same procedure was followed as in Example 1, except that the tourmaline was changed to a second-order modified tourmaline.

[0049] Example 4 Each ingredient mass The parts were 80 parts of unmodified tourmaline, 20 parts of glass powder, 5 parts of negative ion powder, 20 parts of wheat flour, 20 parts of paraffin, and 0.5 parts of oleic acid. After mixing the above raw materials, hot die casting was performed and sintered once at 600 to 800 ° C to form a porous atomizing core.

[0050] Example 5 Each ingredient mass The mixture was dry press molded with 80 parts of secondary modified tourmaline, 5 parts of feldspar, 15 parts of attapulgite, and 20 parts of wheat flour, and sintered once at 600 to 800°C to form a porous atomization core.

[0051] Comparative Example 1 The same procedure as in Example 1 was repeated, except that the tourmaline in Example 1 was replaced with aluminum oxide.

[0052] The negative ion emission performance of the atomizing cores obtained in Examples 1 to 5 and Comparative Example 1 was measured. The negative ion content in solids and air was measured using a negative ion measuring device for solids COM-3010PRO and a negative ion measuring device for air COM-3200PRO II. The negative ions in air were measured using a 1m 3 The measurement was performed for 20 to 60 minutes in a closed space. The sample size of the atomization core was a circular plate with a thickness of 1 cm and a diameter of 10 cm. The measurement results are shown in Table 1.

[0053] [Table 1]

[0054] As can be seen from Table 1, in the present invention, by adding tourmaline, the atomizing core has the function of releasing negative ions, etc. Moreover, the effect of modified tourmaline is better, and the negative ion powder has the same effect.
