Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The following describes embodiments of the present application in detail.

The atomizing core includes heater block and drain part, and the heater block is connected with the power electricity, and the drain part absorbs the tobacco tar from the stock solution cavity, and the heater block utilizes the electric energy to generate heat, atomizes the tobacco tar in the drain part to produce smog. At present, the liquid guiding component can be made of ceramic materials, however, the liquid guiding component made of ceramic materials needs to be added with additives made of special materials in the production and processing process, when the liquid guiding component is heated and atomized by a heating component, the residual additives can be atomized, and meanwhile, fine ceramic dust can be volatilized, so that the safety of the electronic cigarette is poor; meanwhile, the liquid guide part made of ceramic materials has porous and microporous characteristics, and can adsorb the aromatic taste of the electronic cigarette, so that the electronic cigarette has poor taste.

In order to provide an electronic cigarette with good taste and safety, the liquid guide component can adopt cotton fiber bundles which are purely natural and have no additives. However, the cotton fiber bundle is soft, the liquid guide component and the heating component are not firmly combined, and the liquid guide component is heated unevenly during heating, so that the atomization consistency and the fineness of the tobacco tar are poor, and liquid leakage is easily caused; moreover, it is difficult to ensure the consistency of the product in the mass production process.

In order to solve the above problems, the present application provides an atomizing core with good taste, safety, fineness of atomization, moldability, stability and consistency, which will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an atomizing core provided in the present application, where the atomizing core includes: heating part 1 and drain part 2, heating part 1 include heating metal part 11 and connect electric metal part 12, and the drain part 2 adopts short cotton fiber, and short cotton fiber's length is shorter than the cotton fiber, and drain part 2 and heating metal part 11 integrated into one piece.

The power connection metal part 12 is configured to supply electric energy to the heating metal part 11 in a power connection state, and the heating metal part 11 is configured to generate heat by the electric energy to atomize the tobacco tar in the liquid guiding component 2.

The liquid guide component 2 is made of short cotton fibers, the short cotton fibers are cotton fibers with short lengths, the liquid guide component is made of pure natural materials and free of additives, when the tobacco tar in the liquid guide component 2 is atomized, impurities cannot be generated, and the liquid guide component is good in taste and high in safety.

The length of short cotton fiber is shorter than that of common cotton fiber, can adopt processing technology to form the structure of evenly distributed's absorption tobacco tar, compares traditional cotton fiber bundle, and density is higher, and the hardness is bigger, and the pore size uniformity is also higher. Drain part 2 and heating metal part 11 integrated into one piece, when heating metal part 11 atomizes the tobacco tar in the drain part 2, this structure makes the inside of drain part 2 be heated evenly, and is better to the atomizing fineness of tobacco tar.

In terms of processing technology, the liquid guide component 2 and the heating metal part 11 are integrally formed, and the atomizing core is good in formability, stability and consistency of appearance size. Through structural design, make drain part 2 and heating metal portion 11 assemble more easily, reduce the production degree of difficulty, improve production efficiency, promote product quality's stability and uniformity.

In one example, the length of the short cotton fiber used for the liquid guiding component 2 is less than 10 mm. It can be understood that if longer cotton fibers are used, the internal pores are larger and the uniformity is poor due to the soft nature of the cotton fibers. Therefore, the short cotton fiber adopted by the liquid guiding component 2 shortens the common cotton fiber through process processing, so that the length of the cotton fiber is less than 10mm, and after the liquid guiding component 2 and the heating metal part 11 are integrally formed, the size consistency of the inner space of the liquid guiding component 2 is high, the liquid guiding component 2 is heated uniformly during heating and atomization, and the atomization fineness of the tobacco tar is good.

In one example, as shown in fig. 2, the heating metal part 11 is a hollowed metal foil, and the metal foil has a cylindrical shape. The cylindrical structure can make outside air current from the below through the hole of heating part 11, is sucked out with the flue gas after the atomizing together, and the air current passageway is more smooth and easy in the atomizing core. Meanwhile, the cylindrical heating metal part 11 has a more stable structure and is more convenient to assemble.

Moreover, compared with the traditional metal wire structure, the structure is more stable, high in firmness and difficult to deform; the heating area is large, and the atomization effect is good; easier assembly and high consistency in mass production.

In the example shown in fig. 2, the cylindrical metal foil of the heating metal part 11 has a hollow structure. Of course, the metal foil of the heating metal part 11 may have a hollow structure other than the hollow structure of the square-wave shape. For example: rectangular hollow structures, triangular hollow structures, spiral hollow structures and the like.

In the example shown in fig. 2 and 5, the hollow-out structure of the heating metal part 11 includes a bent part 111 at both ends and a non-bent part 112 between the bent parts. The metal area per unit length of the bent portion 111 is not completely the same as that of the non-bent portion 112.

As shown in fig. 2, the conductive area of the bent portion 111 at one end of the zigzag structure of the heating metal portion 11 is larger than that of the non-bent portion 112, and as shown in fig. 2, the metal area per unit length of the bent portion 111 is larger and has a small resistance, and is mainly used for conducting and shaping. The metal area of the unit length of the non-bending part 112 is small, the resistance is large, and the non-bending part is used for heating and atomizing. When heating and atomizing, the temperature requirement of the liquid guide part 2 far from the center is lower, and the temperature requirement of the middle part is higher.

In the zigzag structure shown in fig. 5, the conductive areas of the bent portions 111 at both ends are larger than the conductive areas of the non-bent portions 112, i.e. the resistances of the bent portions 111 at both ends are smaller than the resistances of the non-bent portions 112. Optionally, the resistances at the bent portions at the two ends of the clip structure may be the same or different.

In one example, as shown in fig. 5, both electrodes of the electrification metal part 12 are metal foils. The two electrodes are both in a semi-circular arc shape, and the two metal foils form a similar circular base which can support the heating metal part. The power connection metal part 12 adopts the structural design, and compared with a metal wire, the power connection metal part can provide a larger contact area, and the structure of a power supply is more stable and reliable.

The electric metal 12 is connected to a power supply to provide electric energy for the heating metal part 11, and the heating metal part 11 generates heat by using the electric energy to atomize the tobacco tar absorbed by the liquid guide component 2. In one example, the heating metal part 11 and the electrifying metal part 12 may be in welding contact. In this case, the heating metal part 11 and the contact metal part 12 may be made of the same metal or different metals. In another example, the heating metal part 11 and the electrifying metal part 12 may also be integrally formed. The integrally formed heating member 1 is more stable in structure.

Unlike the hollow-out structure of the heating metal part 11 shown in fig. 2 to 7, in the hollow-out structure of the heating metal part 11 shown in fig. 8 and 11, the metal areas of the bent part 113 and the non-bent part 114 at both ends per unit length are the same, that is, the conductive areas at the positions of the hollow-out structure of the heating metal part 11 shown in fig. 8 and 11 are the same, and therefore, the resistances at the positions of the hollow-out structure of the heating metal part 11 are the same.

In one example, as shown in fig. 8, the heating metal part 11 has a hollow structure with a uniform resistance, and the electric connection metal part 12 includes a metal wire part and a metal sheet part. Wherein, the metal sheet part of the electric connection metal part 12 is at least partially formed integrally with the liquid guiding component 2, and the wire part of the electric connection metal part 12 is exposed out of the liquid guiding component 2. Fig. 9 and 10 show the configuration of the liquid guide member 2 integrally molded with the heating metal part 11, and fig. 10 is a perspective view.

In another example, as shown in fig. 11, the heating metal part 11 has a hollow structure with a uniform resistance, and both electrodes of the electrical connection metal part 12 are metal foils. The two electrodes are both in a semi-circular arc shape, and the two metal foils form a similar circular base which can support the heating metal part. The power connection metal part 12 adopts the structural design, and compared with a metal wire, the power connection metal part can provide a larger contact area, and the structure of a power supply is more stable and reliable.

The heating metal part 11 is a hollow structure with a uniform resistance, and when the electric connection metal part 12 is a semi-arc metal foil, the structure of the liquid guiding component 2 and the heating metal part 11 are integrally formed, as shown in fig. 12 and 13, and fig. 13 is a perspective view.

In one example, as shown in fig. 14, the heating metal part 11 is a spring-like wire. The spring-like wire is also cylindrical. The cylindrical structure can make outside air current pass through the hole of heating part 1 from the below, is sucked out with the flue gas after the atomizing together, and the air current passageway is more smooth and easy in the atomizing core. Meanwhile, the cylindrical heating metal part 11 has a more stable structure and is more convenient to assemble.

In the example shown in fig. 14, the heating metal part 11 includes a first functional part 115 and a second functional part 116, and the resistance value of the first functional part 115 is smaller than the resistance value of the second functional part 116.

As shown in fig. 14, a small number of wires of the heating wire part 11 away from the center may be provided as the first functional part 115, and a wire near the center may be provided as the second functional part 116. Alternatively, as shown in fig. 15, the first functional portions 115 may be provided at both ends away from the center, and the second functional portion 116 may be located between the two first functional portions 115. Alternatively, when the first functional portions 115 are provided at both ends away from the center, the resistances of the second functional portions 116 at both ends may be the same or different.

Optionally, the first functional portion 115 is made of a material with low resistance, and is mainly used for conducting electricity and shaping.

When heating and atomizing, the temperature requirement of the liquid guide part 2 far from the center is lower, and the temperature requirement of the middle part is higher.

In one example, as shown in fig. 16, two connection nodes a and B of the electrifying metal part 12 and the heating metal part 11 are located on different sides of the heating metal part 11. In another example, as shown in fig. 17, two connection nodes C and D of the electrifying metal part 12 and the heating metal part 11 are located on the same side of the heating metal part 11. The structure shown in fig. 11 prevents the short cotton fibers from being blocked by the electric connection metal part 12 and affecting the integral molding effect when the liquid guide member 2 is integrally molded with the heating metal part 11.

In one example, the heating metal part 11 is a spring-shaped wire structure, and when the electric metal part 12 is a wire, the heating metal part 11 and the electric metal part 12 can be in welded contact. Fig. 18, 19 and 20 show the structure of the liquid guiding member 2 integrally formed with the heating metal part 11, and fig. 19 and 20 are perspective views, in which fig. 19 shows two connection nodes a and B of the electrically connecting metal part 12 and the heating metal part 11 on different sides of the heating metal part 11, and fig. 20 shows two connection nodes a and B of the electrically connecting metal part 12 and the heating metal part 11 on the same side of the heating metal part 11.
