Description

Atomizer core assembly and preparation method thereof, and atomizer device Technical Field

The present invention relates to the field of atomization technology, and in particular to an atomization core component and a preparation method thereof, and an atomization device.

Background Art

At present, the atomizer cores in the fields of electronic cigarettes or medical treatment are mainly cotton cores and porous ceramic atomizer cores. The cotton core is the first widely used atomizer core, and the smoke produced by the atomization has a good taste. So far, the design of new electronic cigarette heating elements is still pursuing the effect similar to cotton core atomization. However, since the molding method of the cotton core atomizer core is mainly cotton winding or cotton wrapping, the heating element and the cotton are not tightly combined, the molding and product consistency are poor, and it is easy to produce core sticking or oil frying during atomization, which greatly affects the use effect of the atomizer core. If the cotton is pressed into the heating element by external force, it is very easy to cause damage to the heating element. The porous ceramic atomizer core has also slowly developed in recent years because of its convenient molding, certain strength, good consistency and close combination with the heating element, but the taste brought by the current ceramic atomizer core is still incomparable to the cotton core atomizer core.

Whether the heating element and the cotton are not tightly combined, or the cotton is pressed into the heating element, the atomizer core will become sticky or oily when heating the smoke liquid, which will lead to a lower atomization reduction effect of the smoke liquid.

Summary of the invention

The technical problem to be solved by the present invention is to provide an atomizer core assembly which is integrally formed and has a high degree of reduction of atomized liquid, a preparation method thereof, and an atomizer device having the atomizer core assembly.

Implementation

In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2 , an atomizer core assembly according to an embodiment of the present invention includes a heating element 20 and a fiber atomizer core 10 integrally formed on the heating element 20 .

The fiber atomization core 10 is a columnar structure, which may be but is not limited to a cylinder as shown in Fig. 1. The fiber atomization core 10 has a central through hole 100, which passes through two opposite ends of the fiber atomization core 10 and serves as an atomization channel.

In the embodiment shown in FIG. 1 and FIG. 2 , the heating element 20 is embedded in the fiber atomizer core 10. The heating element 20 may structurally include a heating net 21 embedded in the fiber atomizer core 10, and two pins 22 connected to the heating net 21 and extending out of the fiber atomizer core 10. The two pins 22 are used to connect to a power supply device.

The heating net 21 of the heating element 20 may be embedded on the inner wall surface of the central through hole 100 , or may be partially or completely embedded inside the inner wall surface of the central through hole 100 .

In other embodiments, the fiber atomizer core 10 may also be a polyhedron structure such as a cuboid, and the heating element 20 may be embedded on at least one surface of the fiber atomizer core 10 in a mesh structure.

Furthermore, the fiber atomizing core 10 of the present invention includes the following raw materials and their mass fractions: 1-200 parts of pre-treated main material, 0-2000 parts of pure water, 0-800 parts of binder, and 0-30 parts of dispersant. The main material is preferably 2-200 parts, and more preferably 5-200 parts; the pure water is preferably 5-2000 parts, and the binder is preferably 1-800 parts.

The main material includes at least one of glass fiber, plant fiber and inorganic fiber, and the size is 500 mesh to 10 mm. The plant fiber includes at least one of seed fiber, bast fiber and leaf fiber, and may also include plant fiber products, such as paper, cotton (including cotton linter powder, etc.), etc.

Pure water is used as the solvent, and the binder and dispersant are added flexibly according to the raw material requirements and their addition amounts.

The binder may include at least one of fatty alcohol polyoxyethylene ether, polyacrylamide, polyvinyl alcohol, polyacrylate, starch, sugar, gum, CMC and sodium lignin sulfonate. For the selection of the above binders, for liquid binders, the concentration is preferably 1% to 20%; for solid binders such as powders, it is preferably prepared into a solution with a concentration of 1% to 20%.

The dispersant is added as needed, and may include at least one of an organic small molecule dispersant and a polymer dispersant. The organic small molecule dispersant may include at least one of sodium citrate, sodium stearate, and hydroxyethylethylenediamine, and the polymer dispersant may include at least one of polyacrylamide and hydroxymethylcellulose.

In the present invention, the main material is pre-processed, and the pre-processing mainly includes at least one of mixing tobacco products and overloading flavor additives. Through the pre-processing, the tobacco products and/or flavors are adsorbed onto the main material, adding corresponding odors or aromas to the main material, thereby improving the suction effect after atomization.

The operation method of mixing tobacco products is as follows: grind the tobacco products to a size of 2000 mesh ~ 1mm, and then mix the tobacco products with the main material. The amount of tobacco products added accounts for 5% to 90% of the total mass of the tobacco products and the main material. Among them, the tobacco products include at least one of ordinary tobacco, heat-not-burn tobacco (also known as low-temperature tobacco), mint leaves, cannabis leaves, tea tobacco leaves and edible flowers; the flowers are various edible non-toxic flowers or buds, such as jasmine, rose, honeysuckle, lotus, chrysanthemum, etc.

The operation method of overloading the flavor additive is as follows: the flavor additive is prepared into a flavor solution, preferably with a concentration of 5% to 50%; the main material is loaded into a chromatography column, and the flavor solution is circulated and overloaded in the chromatography column for 1 to 6 hours; then the overloaded main material is vacuum filtered to filter out excess solution, and dried to obtain a main material with flavor molecules adsorbed on the surface.

The flavor additives include at least one of tobacco extracts, cannabis extracts, plant extracts (various harmless extracts of non-toxic and edible plants), natural flavors, synthetic flavors, flavors for tobacco oil, sweeteners, flavorings and surface flavors. Further, the flavorings include sugar substances and organic acids, such as white sugar, brown sugar, honey, glucose, citric acid, tartaric acid, etc.; the surface flavors include non-sugar sweeteners, such as phenylacetic acid, acetic acid, ethyl acetate, vanillin, etc.

The main material was mixed with tobacco products and overloaded flavor additives, and the SEM images (scanning electron microscope images) after treatment were shown in Figures 3 and 4. As can be seen from Figure 3, the overloaded flavor additives can completely infiltrate the main material (fiber) and adsorb in its pore structure. As can be seen from Figure 4, the added tobacco product powder is evenly and firmly adsorbed on the surface of the main material (fiber).

The SEM image of the fiber atomizer core prepared with the main material as the matrix material is shown in Figure 5. As can be seen from Figure 5, since the main material is mainly made of fiber, the interior is loose and porous, and the pores are interconnected, which is used to absorb the smoke liquid; and the high specific surface area of the fiber atomizer core locks the smoke liquid more effectively. Combined with the integrated molding of the fiber atomizer core and the heating element, the fiber atomizer core can fully contact with the heating element to achieve uniform atomization. When used, it not only restores the smoke liquid, but also the pre-treated main material itself can release the corresponding fragrance, avoiding the occurrence of oil frying and core sticking, improving the atomization effect and the reduction degree of smoke liquid, and the reduction degree exceeds that of traditional cotton core atomizer cores and ceramic atomizer cores.

Referring to FIG. 1 and FIG. 2 , the method for preparing the atomizer core assembly of the present invention may include the following steps:

S1. Mix and evenly stir the raw materials of the fiber atomizing core 10 to obtain a mixed material.

S2, placing the heating element 20 in a mold, and filling the mixed material into the mold by at least one of molding, injection, pressure injection and filtration to perform molding treatment, so as to obtain a green body with the heating element 20.

Among them, the molding pressure is 0.1 MPa ~10MPa, and the molding holding time is 0.5min~5min.

The mold cavity of the mold is set according to the required shape of the fiber atomizer core, such as a cylindrical cavity or a multi-faceted cavity, etc., and can be correspondingly formed into a blank with a cylindrical structure or a multi-faceted structure.

Alternatively, the heating element 20 is placed in the mold before the mixed material is filled in the mold, and after the mixed material is filled in the mold, the heating element 20 is at the bottom of the mold cavity of the mold and buried under the mixed material. Alternatively, the heating element 20 is wrapped in the mixed material.

S3, drying the blank with the heating element 20 to form a fiber atomizer core 10, thereby obtaining an atomizer core assembly.

Drying can be carried out in an oven or other equipment. The drying temperature is 60℃~180℃.

Furthermore, the atomizing assembly of the present invention is applied to an atomizing device, where the fiber atomizing core 10 absorbs the atomizing liquid (such as smoke liquid, etc.), and the heating element 20 generates heat after being powered on, and the atomizing liquid is heated and atomized to form smoke. The smoke flows out along the central through hole 100 and the air guide channel and is inhaled by the user.

Referring to Fig. 6, it shows an atomizing device according to an embodiment of the present invention, comprising a housing 1, a liquid storage chamber 2, and an atomizing assembly 3. The atomizing assembly 3 is the atomizing assembly shown in Figs. 1 and 2 of the present invention.

The atomizer core assembly 3 and the oil storage chamber 2 are both arranged in the housing 1 , and the oil storage chamber 2 surrounds the outer circumference of the atomizer core assembly 3 and is connected to the fiber atomizer core 10 of the atomizer core assembly 3 for liquid conduction.

An air guide tube 4 is also provided in the housing 1, one end of the air guide tube 4 is connected to the atomizer assembly 3, and the other end extends to a port of the housing 1, which forms a smoke outlet 200 of the atomizer. The internal channel of the air guide tube 4 forms an air guide channel, which is connected to the central channel 100 on the atomizer assembly 3.

The air guide tube 4 can be independently provided and assembled in the housing 1 , or can be formed integrally with the housing 1 .

The atomizer device may further include a support sleeve 5, an atomizer seat 6, etc. The support sleeve 5 is sleeved on the outer circumference of the atomizer assembly 3, and the axial length of the support sleeve 5 is preferably greater than the axial length of the atomizer assembly 3, so that the fiber atomizer core 10 of the atomizer assembly 3 can be covered inside. The wall of the support sleeve 5 is provided with at least one liquid guide hole, which is connected to the liquid storage chamber 2, and the smoke liquid stored in the liquid storage chamber 2 enters through the liquid guide hole and is adsorbed on the fiber atomizer core 10. The end of the air guide tube 4 away from the smoke outlet 200 of the housing 1 can be matched on the support sleeve 5 through the sealing cover 7.

The atomizer seat 6 is fitted into another port on the housing 1 away from the smoke outlet 200 , and the port can be closed. The support sleeve 5 can be plugged into the central channel of the atomizer seat 6 .

1 and 6 , the two pins 21 of the heating element 20 of the atomizer assembly 3 can extend straight or bend to extend out of the support sleeve 5 and be conductively connected to the conductor 8 inserted in the atomizer seat 6 .

The atomizing device is then electrically connected to the power supply device via the conductor 8 .
