As shown in fig. 1 to 7, the atomizing assembly 10 includes a first liquid guiding member 11, a heating assembly and an electrode, wherein the first liquid guiding member 11 is made of a flexible material, and in general, holes are distributed on the first liquid guiding member 11, and may also be made of a woven material, and the first liquid guiding member is used for adsorbing an atomizing medium, the heating assembly is fixed on the first liquid guiding member 11 by sewing, the electrode is electrically connected with the heating assembly, and after the electrode is electrically connected, the heating assembly is electrified and heated to atomize the atomizing medium on the first liquid guiding member 11.

In some embodiments, the first liquid guiding member 11 includes an atomization surface a and a liquid inlet surface B, and in general, the atomization surface a and the liquid inlet surface B are respectively located at two opposite sides of the first liquid guiding member 11, an atomization medium enters into the first liquid guiding member 11 from the liquid inlet surface B, after the heating component is electrified, the adsorbed atomization medium is heated, and aerosol generated by heating flows out from the atomization surface a under the action of airflow, so that the liquid inlet and atomization are not disturbed. Preferably, the atomization surface a is provided with a concave-convex structure, so that the heating component can sink into the surface of the first liquid guide 11, and the contact area between the heating component and the first liquid guide 11 is increased.

As shown in fig. 8 and 9, the first liquid guiding member 11 may include one liquid guiding layer 111, or may include more than one liquid guiding layers 111 stacked, and when a plurality of liquid guiding layers 111 are used, gaps are formed between the layers, so that part of atomized liquid can be stored, and the use effect is better. Meanwhile, the first liquid guide piece 11 of the multilayer becomes a whole after being sewn, the subsequent assembly is also convenient, and importantly, the multilayer structure can be made of different materials, so that requirements can be met, for example, the liquid inlet direction needs to be made of materials with high liquid guide speed and good oil locking performance, the part of the second wire 13 which is tightly attached to heat needs to be made of high-temperature resistant materials, and the first liquid guide piece 11 of the multilayer can well solve the problem.

When the first liquid guiding member 11 is a multi-layer liquid guiding layer 111, the liquid guiding layer 111 of the atomizing surface a of the first liquid guiding member 11 is made of one material of linen cotton and aramid fiber fabric, or may be formed by knitting the above materials, or may be made of some high-temperature resistant mixed materials.

In addition, when the first liquid guiding member 11 is a multi-layer liquid guiding layer 111, the liquid guiding layer 111 of the liquid inlet surface B of the first liquid guiding member 11 is made of one of non-woven fabrics, gratings and mesh cotton, or may be a combination of several kinds, and further, the liquid inlet surface B is provided with grooves or meshes, so that the liquid conduction is faster, the liquid can be timely supplied during atomization, and the phenomenon that the liquid is not sufficiently supplied to cause the core to stick is avoided.

The first liquid guide 11 may be used in combination with other liquid guide cotton, and preferably, the atomization assembly 10 further includes a second liquid guide attached to the first liquid guide 11, and the second liquid guide is located on a side opposite to the atomization surface a.

The second liquid guiding member may be liquid guiding cotton, porous ceramic, liquid storing cotton, or the like, and the shape of the second liquid guiding member combined with the first liquid guiding member 11 may be a flat plate shape, or may be one of a rolled shape and a cylindrical shape, or a curved shape.

Further, as shown in fig. 1 and 2, in the first embodiment, the heating component includes a flexible first wire 12 and a second wire 13, preferably, the second wire 13 is made of a conductive material, and the first wire 12 and the second wire 13 are respectively sewn to the first liquid guiding member 11 from two opposite sides of the first liquid guiding member 11 and are interwoven with each other, and are respectively fixed to the first liquid guiding member 11 from two sides.

Further, the electrodes include a first electrode 15 and a second electrode 16 electrically connected to the heat generating component, respectively, and preferably connected to both ends of the heat generating component, and connected to the battery component through contacts or wires to supply power to the heat generating component. In other embodiments, the electrode may also include a plurality of electrodes that can be individually connected to the battery assembly.

Correspondingly, in the present embodiment, the side of the second wire 13 is an atomization surface a, the side of the first wire 12 is a liquid inlet surface B, the atomized medium enters the first liquid guide member 11 from the surface of the first wire 12, after the second wire 13 of the conductive material is electrified, the adsorbed atomized medium is heated, and the aerosol generated by heating flows out from the surface of the second wire 13 under the action of the airflow. Of course, when the first wire 12 is made of conductive material and the second wire 13 is made of non-conductive material, the liquid inlet surface B and the atomizing surface a are exchanged, or the first wire 12 and the second wire 13 are made of conductive material, and both surfaces are atomized at the same time, and liquid is fed from the end or side.

Further, in some embodiments, the first wire 12 may be made of a non-conductive material, and of course, the first wire 12 may also be made of a conductive material, and when the first wire 12 is made of a conductive material, the resistance of the second wire 13 is smaller than that of the first wire 12.

The first wire rod 12 and the second wire rod 13 with different resistances on two sides are interwoven with the first liquid guide piece 11 to form an integral structure through the sewing principle of a sewing machine, at least one of the first wire rod 12 and the second wire rod 13 can generate heat, the second wire rod 13 which can generate heat is fixed on the first liquid guide piece 11, the bonding problem of the second wire rod 13 and the first liquid guide piece 11 can be well guaranteed, the heating atomization is facilitated, the dry burning problem cannot occur, and the large-scale production can be realized.

By combining the sewing principle of a sewing machine, one of the wires is changed into a conductive heating wire, so that the heating wire is fixed on the first liquid guide piece 11, the heating wire is assisted by an object and is not easy to separate from a liquid guide base material, and meanwhile, the heating wire can be produced in a large scale and the production cost is low.

Further, the heating component is fixed by sewing and is in good contact with the first liquid guide piece 11, so that loosening failure is avoided; the first wire rod 12 and the second wire rod 13 can adopt finer wires, and as the sectional areas of the first wire rod 12 and the second wire rod 13 can be smaller than those of the prior art, the hot start speed is high, the heat dissipation is also high, the atomizing assembly 10 can be driven by adopting lower power, and the energy is saved; the interweaving mode after the first wire rod 12 and the second wire rod 13 are sewn is beneficial to mass production in a large scale; the wire-shaped process generally adopts die hole wire drawing molding, and the sizes of the produced first wire 12 and second wire 13 are accurately controlled, so that the resistance of the atomization assembly 10 can be more stable.

Generally, the conductive material of the second wire 13 is one or a combination of a plurality of conductive metal alloy wires, conductive metal fiber wires, conductive carbon fiber wires and conductive graphite wires, heat is generated after current is input, the second wire 13 heats after being electrified, in some embodiments, the wire diameter is preferably a round wire with the diameter of 0.03-0.2mm, more preferably 0.11mm, the wire diameter is more suitable and is not easy to break, and the thinner and softer wire is easy to bend, and meanwhile, some requirements of the atomizing device on resistance can be met. Alternative materials for the second wire 13: the nickel-based alloy, the stainless steel series alloy, the chromium-containing alloy, the titanium-containing alloy, the tungsten-containing alloy, the molybdenum-containing alloy, the iron-containing alloy, the tin-containing alloy and other metal materials, or the non-metal conductive materials such as carbon fiber wires, graphite fiber wires and the like, can be filaments formed by twisting one or two of superfine conductive metal wires and conductive non-metal wires together, is thinner, can be filaments with diameters of several micrometers to several tens of micrometers, and is not particularly limited.

The first wire rod 12 for fixing the second wire rod 13 has a wide range of materials, and may be a conductive material or a nonconductive material, and has a wide range of wire diameter, preferably a wire shape of about 0.15 mm.

Specifically, the first liquid guiding member 11 is liquid guiding cotton, after sewing, most of the second wire 13 leaks out of the atomization surface a, and part of the second wire slightly falls into the first liquid guiding member 11, so that when two ends are electrified, liquid on the surface of the first liquid guiding member 11 can be quickly heated to a boiling point to generate atomized steam.

It can be understood that the second wire 13 may be bent, and the bending manner may be a back and forth bending manner or a bending manner of a wave pattern, and in addition, the second wire 13 may be bent, and the bending manner is not limited.

Further, in order to make the area of heat radiation larger, the first optical signal receiving component 4 includes several second wires 13 located on the same side of the first liquid guiding member 11, preferably, the second wires 13 may be two or more, as shown in fig. 11, where each second wire 13 is interwoven to form a mesh structure, or as shown in fig. 12, each second wire 13 may be disposed side by side, or may be combined in an interwoven and side by side manner. The plurality of second wires 13 may also be bent and curved to form a net structure.

When the material of the second wire 13 is softer or the wire diameter is thinner, the interweaving position of the second wire 13 and the first wire 12 may be sunk into the first liquid guiding member 11, or may be flush with the surface of the first liquid guiding member 11.

Further, as shown in fig. 8 to 10, when the second wire 13 has a relatively large wire diameter, for example, 0.15mm or more, bending is not easily formed due to its high hardness, and the second wire 13 may be flush with the surface of the first liquid guiding member 11. When the first wire 12 is a flexible wire such as a relatively soft cotton, linen or aramid fiber, the second wire 13 may be flush with the surface of the first liquid guiding member 11, not immersed in the first liquid guiding member 11, or slightly bent.

In some embodiments, the first wire 12 is made of a non-conductive material, and the atomized medium enters the first liquid guide 11 from the side of the first wire 12. Further, the non-conductive material of the first wire 12 may be a material with high temperature resistance, such as cotton, flax, aramid fiber, glass fiber, ceramic fiber, and the like, which is not limited herein.

In addition, in other embodiments, the first wire 12 may be made of a conductive material, and the resistance of the second wire 13 is smaller than that of the first wire 12. For example, when the atomized medium is viscous, the first wire 12 is made of metal wires, and at this time, the first wire 12 also generates partial heat, which is equivalent to a certain effect of preheating the smoke liquid, reducing the viscosity and accelerating the flow speed.

Since most of the surface of the first wire 12 is trapped in the first liquid guiding member 11 or is at the liquid inlet level B, and since the surface is in contact with the second wire 13 of the first liquid guiding member 11, when the first wire 12 is made of metal, two wires of the first wire 12 and the second wire 13 are equivalent to a parallel state, and the heat generated by the first wire 12 in the direction close to the liquid inlet level B can play a role in heating tobacco tar, which is equivalent to a preheating effect.

The first wire 12 and the second wire 13 are connected in parallel, so that the resistance of the second wire 13 needs to be smaller than that of the first wire 12, so that the power of the second wire is higher than that of the first wire 12, and when the resistance of the second wire 13 is smaller than that of the first wire 12 due to the equal voltage of the parallel circuit, the current flowing through the second wire 13 is larger than that of the second wire 13, and the temperature generated by the thermal effect of the resistance is higher.

In some embodiments, as shown in fig. 3 and 5, the first electrode 15 and the second electrode 16 are formed by sewing conductive wires onto the first liquid guiding member 11, and it can be appreciated that one of the first electrode 15 and the second electrode 16 may also be formed by sewing conductive wires onto the first liquid guiding member 11, which is beneficial to batch and automatic production of the atomization assembly.

Further, the first electrode 15 and the second electrode 16 are located on the same side of the first liquid guiding member 11, preferably, the first electrode 15, the second electrode 16 and the second wire 13 are the same conductive wire, and the first electrode 15, the second electrode 16 and the second wire 13 can be sewn by one conductive wire at a time, so that the production efficiency is improved.

Of course, in other embodiments, the first electrode 15 may be located at a side where the first wire is located, the second electrode 16 may be located at a side where the second wire 13 is located, the first electrode 15 and the first wire are made of the same conductive wire, the first electrode 15 and the first wire 12 are made of the same conductive wire, the second electrode 16 and the second wire 13 are made of the same conductive wire, and the second electrode 16 and the second wire 13 are made of the same conductive wire.

Further, the first electrode 15 and the second electrode 16 formed by sewing can be provided with a conductive layer 17, so that the resistance is stable, and the external connection of leads or contacts is facilitated. In some embodiments, the conductive layer 17 is formed of a conductive paste or paste, which may be coated or printed.

It will be appreciated that in other embodiments, the conductive layer 17 may be a metal sheet, and attached to the first electrode 15 and the second electrode 16. The metal sheet can be made of nickel, stainless steel, copper, aluminum foil and the like, and then the metal sheet is penetrated by a sewing mode to be sewn on the first liquid guide piece 11, so that the metal sheet is fixedly compounded together.

In addition, in other embodiments, one or both of the first electrode 15 and the second electrode 16 are plugged onto the first liquid guiding member 11, preferably by metal riveting, to clamp and fix the heating assembly, and then by contact or lead-out wire to supply power to the atomizing assembly.

Because the first liquid guiding piece 11 is fluffy, more liquid needs to be stored, the liquid leakage preventing effect is better, liquid guiding cotton with higher fluffiness is adopted, when the wire diameters adopted by the filiform first wire 12 and the second wire 13 of the heating component are smaller, for example, the wire diameter is smaller than 0.08mm, the heated filiform track is sunk into the liquid guiding cotton due to the fluffy liquid guiding cotton, the problem that the liquid guiding cotton is completely wrapped is caused, atomized steam cannot emerge from the liquid guiding cotton, and carbon deposition is easily formed on the liquid guiding cotton.

Further, in order to improve the above problems, in the present embodiment, the first liquid guiding member 11 is sewn with a supporting wire 18 for supporting the first wire 12, the second wire 13 and the electrode, and the supporting wire 18 is made of an insulating material, so as to avoid the problem of heat generation after conduction. In other embodiments, according to the wire diameters of the first wire 12, the second wire 13 and the electrode, when the first wire 12, the second wire 13 and the electrode may be recessed, the support wire 18 is sewn on the corresponding positions of the first wire 12, the second wire 13 and the electrode.

Generally, the supporting wires 18 are disposed side by side along the same direction and are staggered with the first wire 12, the second wire 13 and the electrode, so that the supporting wires 18 provide support for the first wire 12, the second wire 13 and the electrode. In other embodiments, the support wire 18 is cross-stitched to form a net, and the first wire 12, the second wire 13, and the electrode can be supported by the support wire 18 regardless of the direction of stitching.

The strip-shaped or grid-shaped supporting wires 18 are sewn on the liquid-guiding cotton, and then the heating components and the electrode parts are sewn, so that the wire-shaped or grid-shaped supporting wires are equivalent to the wire-shaped or grid-shaped supporting wires, and the heating wire-shaped tracks are not easy to sink into the liquid-guiding cotton.

Further, the present application also provides a process for manufacturing the atomizing assembly 10 according to the first embodiment, which includes the following steps:

Specifically, the method further comprises the following steps: the electrode is formed by sewing conductive wires on the liquid-guiding substrate, and further, after the electrode is formed by sewing, a conductive layer 17 is arranged on the electrode.

The sewing wiring process is adjusted according to the specific shape requirements of specific bending and bending of the first wire rod 12 and the second wire rod 13.

Further, the first electrode 15 and the second electrode 16 may be formed by sewing conductive wires, preferably, when the first electrode 15 and the second electrode 16 are located at the same side, the conductive wires of the first electrode 15 and the second electrode 16 and the second wire 13 are sewn to be the same, so that the production efficiency of the atomization assembly can be improved. Of course, only one of the first electrode 15 and the second electrode 16 may be sewn.

Preferably, as shown in fig. 5, the manufacturing process further includes the step of providing the conductive layer 17 on the first electrode 15 and the second electrode 16 after the first electrode 15 and the second electrode 16 are sewn, and in some embodiments, coating or printing conductive paste on the first electrode 15 and the second electrode 16 to form the conductive layer 17, or sewing a metal sheet on the first electrode 15 and the second electrode 16 to form the conductive layer 17.

and a heating component is sewn on the liquid guide substrate.

Specifically, the method further comprises the following steps: providing flexible second wires 13, wherein the second wires 13 are made of conductive materials, and the second wires 13 are arranged on the liquid guide base material in a penetrating way so as to be sewn on the liquid guide base material to form the heating component. Preferably, the second wire 13 is interposed between two opposite sides of the liquid guiding substrate.

Further, the method also comprises the following steps: an electrode is disposed on the liquid guiding substrate, and is electrically connected with the first optical signal receiving component 4.

Specifically, the electrode is formed by sewing a conductive wire on the liquid-guiding substrate, and further, after the electrode is formed by sewing, a conductive layer 17 is provided on the electrode.

In some embodiments, the first electrode 15 and the second electrode 16 may be formed by sewing conductive threads, preferably, when the first electrode 15 and the second electrode 16 are located on the same side, the conductive threads of the first electrode 15 and the second electrode 16 are sewn to be the same as the second wire 13, so that the production efficiency of the atomization assembly may be improved. Of course, only one of the first electrode 15 and the second electrode 16 may be sewn.

And in combination with fig. 13, when the size of the liquid guiding substrate is smaller, the liquid guiding substrate can be used as the first liquid guiding member 11, or a plurality of groups of heating components and electrodes can be sewn on a large liquid guiding substrate in a partitioning manner in advance, preferably, the plurality of groups of heating components and electrodes are sewn at one time, the circuits of all the regions are connected, and after the sewing is completed, the liquid guiding substrate is cut through a cutting mode to form a plurality of atomizing components with the heating components and the electrodes.

Further, as shown in fig. 16 to 18, in the third embodiment, the heat generating component includes the heat generating body 19 and the fixing wire 191, and the fixing wire 191 is sewn on the liquid guiding substrate to fix the heat generating body 19. The heating element 19 adopts a sewing method, and the heating element 19 is fixed on the liquid guide base material through the fixing wire 191, so that the heating element 19 is in good contact with the liquid guide base material, can be fully atomized, and can be conveniently assembled subsequently, so that the heating element 19 is not easy to deform.

The heat generating body 19 may be a flat plate-shaped heat generating sheet having a heat generating line 192 formed of a planar metal by cutting, punching, etching, or the like. Preferably, the heating element 19 may be net-shaped, and in other embodiments, the heating element 19 may be in a shape having a net or a line shape.

In the present embodiment, the heating element 19 includes two heating wires 192 arranged side by side and a plurality of supporting portions 193 connected to the heating wires 192, respectively, and the supporting portions 193 and the heating wires 192 are connected to each other to form the mesh-shaped heating element 19. The electrodes are used for being externally connected with a lead wire or directly contacted with an external electrode, and the electrodes comprise a first electrode 15 and a second electrode 16 which are respectively connected with two ends of the heating circuit 192 and are used for being connected with a power supply, and the heating circuit 192 heats after being electrified.

In this embodiment, the first electrode 15 and the second electrode 16 and the heating element 19 are integrally formed, and in other embodiments, the first electrode 15 and the second electrode 16 may be formed by sewing conductive wires on the first liquid guiding member 11 and electrically connected to the heating element 19.

In other embodiments, a supporting part 193 is connected to one side or both sides of the heat generating wire 192, the heat generating wire 192 is connected between the electrodes, heat is generated when power is supplied to both ends of the electrodes, and the supporting part serves to connect a plurality of heat generating wires 192, so that the heat generating part has a certain strength.

The fixing wire 191 for fixing the heating element 19 may be one wire inserted between the liquid-guiding cotton or two wires intersecting each other, and the fixing wire 191 needs to be made of non-conductive wires or fibers. The fixing wire 191 may be multiple or one.

Since the current flows in the circuit for the shortest distance, but the support part connected with the heat generating circuit 192 does not form a loop, the support part connected between the two heat generating circuits 192 does not pass the current although in the loop, and therefore, the heat is mainly the heat conducted from the heat generating circuit 192 during heat generation, and the heat is far lower than the heat generating part. Therefore, the position where the fixing wire 191 is sewn is preferably the position of the supporting portion of the heating element 19 because the temperature of the supporting portion of the heating element 19 is low and the temperature resistance requirement of the fixing wire 191 for fixing the heating element 19 is relatively low.

The advantage of choosing this heating element 19 is:

1. the heating element 19 can adopt a stamping mode to facilitate mass production

2. The distance between the heating lines 192 of the heating element 19 and the shape of the heating lines 192 are more regular, and the heat distribution is more stable, balanced and consistent.

3. The electrode part can be designed into a larger area, and the external lead wire or the electrode part can be conveniently contacted with the atomizing device electrode.

Further, as shown in fig. 19, when the heating element 19 is net-shaped, a plurality of thin conductive wires may be used to weave the heating element 19 into net-shaped, or a conductive sheet metal or conductive film material may be used to punch or etch the mesh to form an entire grid or mesh, and as a net-shaped heating structure, the fixing wire 191 may be sewn on the first liquid guide 11 to fix the heating element 19. The heating element 19 has a plurality of penetrating meshes, and has a certain resistance value after being cut into a certain size, so that the heating element can be applied to the field of resistance heating.

The heating element 19 may also be a mesh structure formed by weaving other conductive fibers and non-conductive fibers, such as a cloth structure formed by mixing and weaving carbon fibers and cotton fibers, wherein the carbon fibers have the function of conductive wires, heat is generated after two ends of the carbon fibers are electrified to heat atomized liquid, the cotton fibers conduct liquid and weave with the carbon fibers, so that a better fixing function is achieved, and the conductive wires are not limited to the carbon fibers.

The heating element 19 of a screen structure is usually used in a size of 50 to 400 mesh (referring to the number of meshes of one square inch). The mesh openings are smaller, the liquid tension can enable the heating element to form a film between the mesh openings, oil leakage is not easy to occur, and each part of the heating element is contacted with the conductive net, so that the heating element has a larger atomization area.

The heat generating body 19 is relatively more uniform in heat generation, has a larger heat generation area, and tends to be a structure that generates heat over the whole surface. The heat generated by the netlike heating body 19 is more uniform, the heating area is larger, the mesh spacing and the heating track of the heating body 19 are more regular, and the heat distribution is more stable, balanced and consistent.

Further, the present application also provides a process for manufacturing the atomizing assembly 10 according to the third embodiment, which includes the following steps:

providing a flexible liquid-conducting substrate;

and a heating component is arranged on the liquid guide base material through sewing.

Specifically, in this embodiment, the method further includes the steps of: the heating element 19 and the fixing thread 191 are provided, and the fixing thread 191 is sewn on the liquid guiding base material to fix the heating element 19.

In this embodiment, the electrode and the heating element 19 are integrally formed, and in other embodiments, the electrode may be disposed on the liquid guiding substrate, for example, by sewing, and the conductive layer 17 may be disposed on the electrode to electrically connect the electrode and the heating element 19 in the manner described in the first embodiment and the second embodiment.

When the size of the liquid guiding base material is smaller, the liquid guiding base material can be used as the first liquid guiding piece 11, or a plurality of groups of heating components and electrodes can be sewn on a large liquid guiding base material in a partitioning manner in advance, preferably, the plurality of groups of heating components and electrodes are sewn at one time, the circuits of all the regions are connected, and after the sewing is finished, the liquid guiding base material is cut through a cutting mode to form a plurality of atomization components with the heating components and the electrodes.

The heating components of the atomizing assembly 10 can be sewn on the first liquid guide piece 11, and the structure of the atomizing assembly 10 has the following advantages: the production implementation is simpler and easy to implement, and based on the principle of sewing, the heating material is fixed on the liquid guide base material, so that an atomization component which has good reliability, is easy for mass production and has good heating and liquid guide base material contact is formed, and the pain points that the liquid guide base material is easy to dry heat due to poor contact with the heating component and the heating component is easy to deform and difficult to take in the application process of the flexible liquid guide base material such as liquid guide cotton are solved.

It will be appreciated that the above technical features may be used in any combination without limitation.
