Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomizers, and in particular to a method for preparing a heating component, a heating component and an electronic atomizer. Background Art

[0002] Electronic atomizers, also known as virtual cigarettes and e-cigarettes, are non-combustion tobacco substitutes. As the harm of traditional cigarettes is gradually recognized by the public, electronic atomizers have been increasingly accepted by smoking consumer groups and are gradually expanding their market share.

[0003] The essence of an electronic atomizer is an aerosol generating device, which is connected to the atomizer core through a battery. The battery provides electrical energy to heat the heating component in the atomizer core, atomize the smoke oil in the oil tank, and thus generate an aerosol for the user to inhale. Therefore, the heating component is the core component of the electronic atomizer, and the heating element in the heating component is the key component of the electric heat conversion. At present, the commonly used heating elements on the market are three-dimensional, reaching the millimeter level, and therefore have a large thickness. The thicker the thickness of the heating element, the lower the heating efficiency and the worse the atomization effect. In order to facilitate users to carry, electronic atomizers are currently developing towards miniaturization and portability. Therefore, the volume of the heating element in the electronic atomizer is getting smaller and smaller. How to make the volume of the heating element very small and further reduce its thickness, so that the smoke oil is spread on the heating element in a very thin state, thereby improving the heat conversion efficiency and increasing the reduction degree of the smoke oil, is the key to improving the atomization effect of the electronic atomizer.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0060] As described in the background technology, the heating component is the core component of the electronic atomizer, and the heating element in the heating component is the key component of the electric heat conversion. At present, the commonly used heating elements on the market are three-dimensional, reaching the millimeter level, and therefore have a large thickness. The thicker the thickness of the heating element, the lower the heating efficiency and the worse the atomization effect. In addition, in order to facilitate users to carry, electronic atomizers are currently developing towards miniaturization and portability, so the volume of the heating element in the electronic atomizer is getting smaller and smaller. If the volume of the heating element can be made very small, its thickness can be further thinned, so that the smoke oil can be spread on the heating element in a very thin state, this can further improve the heat conversion efficiency, increase the reduction degree of the smoke oil, and thus improve the atomization effect of the electronic atomizer.

[0061] In order to solve the above problems, the inventors of the present application have conducted in-depth research and designed a method for preparing a heating component with extremely thin thickness, and a heating component prepared based on the preparation method.

[0062] The following uses an electronic cigarette as an electronic atomizer as an example to specifically describe the structure of the heating component provided by the present application and the method for preparing the heating component. The electronic atomizer includes a heating component prepared based on the method for preparing the heating component, and the heating component is used to generate heat under the action of the electric energy provided by the battery in the electronic atomizer, thereby atomizing the atomizing medium in the electronic atomizer to generate an aerosol for the user to inhale.

[0063] This embodiment is only used as an example and does not limit the technical scope of the present application. It is understood that in other embodiments, the heating component of the present application is not limited to being used in electronic cigarettes, but can also be used in any other type of atomizer, and can also be used in any other type of small electronic products, which is not limited here.

[0064] The following combination Figures 1 to 12 , introduces the preferred implementation methods of the heating component and the method for preparing the heating component provided in this application.

[0065] like Figure 1 As shown, a heating component 10 of an electronic atomizer includes a heating element 100 and an electrode connecting portion 200 integrally connected to the heating element 100. The electrode connecting portion 200 is used to connect a power source so that the heating element 100 generates heat, thereby heating the atomizing medium of the electronic atomizer.

[0066] In some embodiments, the heating element 100 is a mesh structure, having a plurality of alternately overlapped threads 110, the threads 110 including a plurality of warps 111 arranged at intervals along a first direction and a plurality of wefts 112 arranged at intervals along a second direction, and in the first direction and the second direction, the warps 111 and the wefts 112 are alternately overlapped with each other using a weaving process. In the figure, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction. The angle between the first direction and the second direction is 0° to 180°, and the third direction is perpendicular to both the first direction and the second direction.

[0067] In the embodiment shown in the figure, the first direction and the second direction are perpendicular to each other, so that in the heating element 100 shown in the figure, the warp 111 and the weft 112 are perpendicular to each other, and the weaving form of the heating element 100 is a vertical pattern. When the angle between the first direction and the second direction is not a right angle, that is, when the angle between the warp 111 and the weft 112 is not a right angle, the weaving form of the heating element 100 is an inclined pattern.

[0068] Preferably, the diameter of the wire 110 is 5 to 50 μm, so that the size of the woven heating element 100 in the third direction is also smaller, so that the heating element 100 has a thinner thickness. In one embodiment, the thickness of the heating element 100 is 10 to 100 μm. Further, the mesh structure of the heating element 100 can be woven entirely from metal wires, that is, the warp 111 and the weft 112 are both metal wires, or the metal wire 110 can be mixed with other high-temperature resistant wires, that is, the warp 111 is a metal wire, the weft 112 is a high-temperature resistant wire, or the warp 111 is a high-temperature resistant wire, and the weft 112 is a metal wire. The material of the wire 110 can be stainless steel, nickel alloy, precious metal, carbon fiber, graphite fiber, etc. The shape of the cross-section of the wire 110 is not limited, and can be circular, rectangular, triangular or other special shapes.

[0069] Furthermore, two adjacent warp threads 111 and two adjacent weft threads 112 together enclose a mesh 101 , so that a plurality of mesh holes 101 arranged at intervals are formed on the heating element, and the aperture of each mesh hole 101 is 10 to 200 μm.

[0070] Specifically, Figures 2 to 7 As shown, each weft thread 112 is in an S-shaped shape, including a plurality of weft overlap segments 1121 and weft load-bearing segments 1122 that are alternately connected in sequence; correspondingly, each warp thread 111 also is in an S-shaped shape, including a plurality of warp overlap segments (not shown in the figure) and warp load-bearing segments (not shown in the figure) that are alternately connected in sequence.

[0071] In an optional embodiment, each warp overlap section and each warp bearing section respectively have an opening, and in the third direction, the opening of the warp overlap section and the opening of the warp bearing section are opposite to each other. Similarly, each weft overlap section 1121 and each weft overlap section 1121 also respectively have an opening, and in the third direction, the opening of the warp overlap section and the opening of the warp bearing section are opposite to each other. Thus, when the warp 111 and the weft 112 are overlapped, in the first direction, one weft bearing section 1122 of each weft 112 is overlapped by at least one warp 111, and one weft overlap section 1121 of each weft 112 is overlapped with at least one warp 111; in the second direction, one warp bearing section of each warp 111 is overlapped by at least one weft 112, and one warp overlap section of each warp 111 is overlapped with at least one weft 112.

[0072] It should be noted that the warp overlap section or the warp load-bearing section of each warp thread 111 and the weft overlap section 1121 or the weft load-bearing section 1122 of each weft thread 112 are not limited to the structure with one end open along the third direction as shown in the figure, but can also be a structure that is not open along the third direction, that is, a ring-shaped structure. In this case, the warp thread 111 is passed through the weft overlap section 1121 or the weft load-bearing section 1122, or the weft thread 112 is passed through the warp overlap section or the warp load-bearing section, and mutual overlap between the warp threads 111 and the weft threads 112 can also be formed.

[0073] Please continue reading Figures 2 to 7 , are three embodiments of the overlapping mode of the warp 111 and the weft 112. In the first embodiment, as Figure 2 and Figure 3 As shown, it is a plain weave, in which the warp threads 111 and the weft threads 112 are overlapped every other silk thread 110, and the warp threads 111 and the weft threads 112 are interwoven to form parallel patterns, that is, in the first direction, a weft load-bearing section 1122 of each weft thread 112 is overlapped by a warp thread 111, and a weft overlap section 1121 of each weft thread 112 is overlapped to a warp thread 111; in the second direction, a warp load-bearing section of each warp thread 111 is overlapped by a weft thread 112, and a warp overlap section of each warp thread 111 is overlapped to a weft thread 112.

[0074] In the second embodiment, if Figure 4 and Figure 5As shown, it is a twill weaving method, where the warp 111 and the weft 112 are staggered to form a diagonal pattern. That is, in the first direction, a weft bearing section 1122 of each weft 112 is overlapped by at least two sequentially arranged warp 111, and in the figure, a weft bearing section 1122 of each weft 112 is overlapped by six sequentially arranged warp 111, and a weft overlapping section 1121 of each weft 112 is overlapped with one warp 111; in the second direction, a warp bearing section of each warp 111 is overlapped by one weft 112, and a warp overlapping section of each warp 111 is overlapped with at least two sequentially arranged weft 112, and in the figure, a warp overlapping section of each warp 111 overlaps with six sequentially arranged weft 112.

[0075] In the third embodiment, if Figure 6 and Figure 7 As shown, it is a weaving method of satin, and the warp overlapping segments and the weft bearing segments form some separate and unconnected overlapping points in the mesh structure of the heating element 100. That is, in the first direction, a weft bearing segment 1122 of each weft 112 is overlapped by a warp 111, and a weft overlapping segment 1121 of each weft 112 is overlapped with at least two sequentially arranged warps 111. In the figure, a weft overlapping segment 1121 of each weft 112 is overlapped with five sequentially arranged warps 111; in the second direction, a warp bearing segment of each warp 111 is overlapped by at least one weft 112. In the figure, a weft overlapping segment 1121 of each weft 112 is overlapped with five sequentially arranged warps 111. It should be noted that satin can have a variety of weaving methods. Figure 6 and Figure 7 Only one type of satin weaving method is shown, and they are not listed here one by one.

[0076] Thus, the braiding methods of the above three embodiments can make the wire 110 of the heating element 100 have a firm texture and a smooth surface, so that the wire 110 is not easily broken during the use of the heating component 10, thereby making the heating element 100 not easily damaged.

[0077] Furthermore, if Figures 8 to 10 As shown, the electrode connection part 200 includes a positive connection part 210 and a negative connection part 220 arranged at opposite ends of the heating element 100. The positive connection part 210 is used to connect the positive pole of the power supply, and the negative connection part 220 is used to connect the negative pole of the power supply so that the heating component 10 can be powered on to generate heat.

[0078] In one embodiment, the positive electrode connecting portion 210 and the negative electrode connecting portion 220 are respectively in the form of a cubic block structure, such as Figure 8 As shown, the two ends of the heating element 100 are integrally welded by laser welding, or as shown in FIG. Fig. 9As shown, the conductive silver paste is infiltrated into the opposite ends of the heating element 100 through the printing process, that is, the opposite ends of the heating element 100 are respectively embedded in the positive electrode connecting portion 210 and the negative electrode connecting portion 220. In another embodiment, as Fig.10 As shown, the positive electrode connection part 210 and the negative electrode connection part 220 can be a thin film structure, which is covered on the surfaces of the opposite ends of the heating element 100 through a PVD coating process, or a thin plate structure, which is adhered to the surfaces of the opposite ends of the heating element 100 through a metal stamping process.

[0079] In this way, through the above loading method of the electrode connecting part 200, the overall thickness of the heating component 10 can be kept extremely thin without occupying space, and the heating efficiency of the heating component 10 can be guaranteed.

[0080] Furthermore, if Fig.11 As shown, the preparation method of the heating component 10 is introduced. The specific steps of the preparation method are as follows:

[0081] In the first step S1, a reinforcing layer 40 is attached to the surface of the wire 110. As described above, the diameter of the wire 110 used in the heating element 100 is 5 to 50 μm. The extremely thin wire 110 is easily broken during the weaving process, and thus cannot be woven into a mesh. In order to prevent the wire 110 from being easily broken during the weaving process, a reinforcing layer 40 needs to be attached to the surface of the wire 110 before weaving, so that the wire 110 has a certain strength and toughness.

[0082] Specifically, step S1 includes the following steps:

[0083] S11, immersing the wire 110 in a water-soluble resin 30 solution, so that the water-soluble resin 30 adheres to the surface of the wire 110, so as to form a strengthening layer 40 on the surface of the wire 110. Fig.12 As shown, the wire 110 is passed through a groove containing a water-soluble resin 30 in a slightly stretched state to ensure that the wire 110 can be completely immersed in the water-soluble resin 30, so that the surface of the wire 110 can be adhered with the water-soluble resin 30, thereby forming a reinforcement layer 40. The reinforcement layer 40 is a layer of fiber-reinforced resin composite material, which ensures that the wire 110 can have a certain strength and toughness during the weaving process.

[0084] In this step, the thickness of the strengthening layer 40 needs to be controlled. The thickness of the strengthening layer 40 is preferably 1 / 10 to 1 / 2 of the diameter of the wire 110. Controlling the thickness of the strengthening layer 40 specifically includes the following steps:

[0085] S111, adjusting the concentration of the water-soluble resin 30 solution according to the diameter of the wire 110;

[0086] S112, controlling the time and speed of the silk thread 110 passing through the water-soluble resin 30 solution to adjust the thickness of the reinforcement layer so that the thickness of the reinforcement layer is controlled to be 1 / 10 to 1 / 2 of the diameter of the silk thread 110; preferably, the silk thread 110 with the reinforcement layer 40 attached can be quickly dried to facilitate weaving the silk thread 110 into a mesh-shaped heating element 100.

[0087] In the second step S2, the heating element 100 is obtained by weaving the wire 110 attached with the reinforcement layer 40. Specifically, a high-precision weaving machine is used to weave the wire 110 attached with the reinforcement layer 40 into a mesh structure. The wire 110 can be woven into the plain weave, twill weave or satin weave mentioned above, and can be woven with all metal wires, or mixed with metal wires and high-temperature resistant wires to weave into corresponding tissue forms.

[0088] The third step S3 is to remove the reinforcing layer 40 attached to the surface of the wire 110 of the heating element 100. After the wire 110 is woven into a mesh structure of the heating element 100, it is not necessary to attach the reinforcing layer 40 to the surface of the wire 110. The reason is that once the reinforcing layer 40 is still attached to the surface of the wire 110 of the heating element 100, when the heating element 100 is heated in the future, the reinforcing layer 40 will be burned into carbon deposits and will volatilize substances that are harmful to the human body.

[0089] In this step, the following steps are specifically included:

[0090] First, S31, the heating element 100 with the reinforcing layer 40 attached to the wire 110 is immersed in water for a period of time and moved in a forward direction. Since the water-soluble resin 30 has the characteristic of dissolving in water, after immersion, the reinforcing layer 40 on the surface of the wire 110 can be completely dissolved in water, thereby removing the reinforcing layer 40.

[0091] Then, in S32, the heating element 100 is dried to obtain the desired heating element 100.

[0092] However, after step S31, although the reinforcing layer 40 is eliminated, there will be gaps between the overlapping wires 110, so that the heating element 100 is not tight. Preferably, since the wires 110 have a certain elasticity, after step S31, step S310 can be added: stretching the heating element 100 to further eliminate the gaps caused by the reinforcing layer 40.

[0093] In step S310, the following steps may be specifically included:

[0094] S311, in the forward direction of the heating element, the portion at the edge of the heating element 100 advances faster than the portion at the middle of the heating element 100, so the silk thread 110 along the forward direction may be extended, that is, along the forward direction, the two ends of the heating element 100 in the direction are slightly stretched outward in a direction away from the heating element 100;

[0095] S312. Similarly, in a direction perpendicular to the aforementioned forward direction, both ends of the heating element 100 in this direction are also extended, that is, along a direction perpendicular to the aforementioned forward direction, both ends of the heating element 100 in this direction are also slightly stretched outward in a direction away from the heating element 100.

[0096] Thus, after biaxial stretching, the wires 110 on the heating element 100 are slightly straighter than the initial state after weaving, which can reduce the gaps between the wires 110 caused by the reinforcing layer 40, thereby making the wires 110 of the heating element 100 closer and making the heating element 100 more solid.

[0097] The fourth step S4 is to load the electrode connection part 200 on the end of the heating element 100 to obtain the heating component 10. As described above, the electrode connection part 200 can be loaded on the end of the heating element 100 by laser welding, conductive silver paste printing or PVD vacuum coating, so that the electrode connection part 200 is integrally connected with the heating element 100, and then die-cut or cut into corresponding shapes to finally obtain the finished heating component 10.

[0098] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
