Best Mode for Carrying Out the Invention

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 Figures 1 to 3, the aerosol forming unit 10 in a preferred embodiment of the present invention includes an atomizing unit 11 formed by winding an atomizing component 11a, a filter 12 arranged at one end of the atomizing unit 11, a filter 13 arranged at the end of the atomizing unit 11 away from the filter 12, and a support tube 14 covering the atomizing unit 11 and the filter 12. The filter 12 part is mainly in contact with the human body, filters impurities and large particles, and cools down the smoke entering the mouth so that the temperature of the smoke entering the mouth is moderate. The filter 13 can prevent some large particles of dust and other substances from entering, and at the same time prevent shredded tobacco and the like from leaking out of the aerosol forming unit 10.

As shown in Figure 4, the support tube 14 can connect the atomization unit 11 and the filter tip 12 together. Preferably, the support tube 14 is a rolled support paper, which can make the aerosol forming unit 10 have a certain hardness. First, it can make the aerosol forming unit 10 be smoothly inserted into the heater 20, and secondly, it can support the atomization unit 11 so that the electrode 113 of the atomization unit 11 can be positioned, so that the elastic contact contact 211 on the heater 20 and the electrode 113 on the aerosol forming unit 10 are in good contact.

As shown in Figures 5 and 6, the atomization component 11a includes a solid aerosol-forming matrix 111, a heating body 112, and an electrode 113. The solid aerosol-forming matrix 111 is in the form of a flexible sheet. Preferably, the extracted fibers of herbal plants can be made into a flexible and bendable paper-like or sheet-like solid aerosol-forming matrix 111. As shown in Figures 7 and 8, it can be curled or folded to form an atomization unit 11 in a specific shape such as a column or block, and assembled with a filter tip 12 etc. into a columnar or block-shaped aerosol-forming unit 10 which is inserted into the heater 20.

The electrode 113 of the atomizing unit 11 is exposed, and after the aerosol forming unit 10 is inserted into the heater 20, the electrode 113 contacts and conducts with the contact point in the heater 20, and supplies power to the atomizing unit 11 for heating and atomization. Of course, it can be understood that the atomizing assembly 11a can also be bent to form the atomizing unit 11, or the atomizing unit 11 can be formed by combining winding and bending at the same time.

The heating body 112 includes a flexible first wire 1121 sewn on the solid aerosol-forming substrate 111. The first wire 1121 is a conductive material and is fixed on the sheet-shaped solid aerosol-forming substrate 111 after sewing. The electrode 113 includes two conductive electrodes 1131 electrically connected to the first wire 1121 respectively. The conductive electrodes 1131 can be in contact with the contact points on the heater 20 to conduct, so that the heater 20 supplies power to the heating body 112 and heats the solid aerosol-forming substrate 111 to form an aerosol.

As shown in combination with FIGS. 5 and 6 , in some embodiments, the first wire 1121 includes a seam 1122 that passes from the first side A to the second side B opposite to the first side A and then returns to the first side A. The seam 1122 allows the first wire 1121 to be sutured to the solid aerosol-forming substrate 111, so that the first wire 1121 and the solid aerosol-forming substrate 111 are better fitted, stably combined, and not easy to loosen. According to the suture length of the first wire 1121, one or another number of seams 1122 can be set along the suture routing direction to suture the first wire 1121 to the solid aerosol-forming substrate 111.

It can be understood that in some embodiments, the seam portion 1122 may include a first section 1122a and a second section 1122b connected in sequence, and the first section 1122a and the second section 1122b are located in the same sewing hole, that is, after the seam portion 1122 penetrates the solid aerosol forming matrix 111 from the first side A to the second side B, it returns to the first side A from the original sewing hole, so that the seam portion 1122 is buried in the solid aerosol forming matrix 111, and the solid aerosol forming matrix 111 can be heated.

Typically, the first wire 1121 is sewn along a certain path to form the heating body 112, and there will be a number of seams 1122 to ensure a stable connection with the solid aerosol-forming matrix 111 and to ensure a sufficient heating range. Furthermore, the first wire 1121 also includes a connecting section 1123 located on the first side A and connected between two adjacent seams 1122, which can make the heating body 112 longer along the first side A and increase the heating range. Of course, only one seam 1122 can be provided, and the two ends of the heating body 112 are fixed to the solid aerosol-forming matrix 111 through electrodes 113.

The heating body 112 is formed by stitching wires, which is conducive to the use of thinner heating wires. Since the cross-sectional area can be made smaller, the hot start speed is fast and the heat dissipation is also fast. Lower power can be used to drive the solid aerosol to form the matrix 111, which is beneficial to energy saving. The heating body 112 is formed by stitching wires, which is also conducive to large-scale production. The production process of filamentary wires generally adopts die hole drawing and molding, and the size control is precise, which can make the resistance of the heating body 112 more stable.

The wire diameter is usually relatively thin, and the cross-sectional area is generally φ0.2mm round wire. The heating body 112 formed after the wire is sewn to the solid aerosol forming matrix 111 and the solid aerosol forming matrix 111 are made into an integral structure, and the heating body 112 is fixed on the solid aerosol forming matrix 111. In this way, the solid aerosol forming matrix 111 can be used as a carrier of the heating body 112, which can prevent the heating body 112 formed by the wire from deforming. At the same time, it can well ensure the fitting problem between the heating body 112 and the solid aerosol forming matrix 111, and it can also facilitate large-scale automated production.

The materials that can be selected for the first wire 1121 include: nickel-based alloys, stainless steel series alloys, chromium-containing alloys, titanium-containing alloys, tungsten-containing alloys, molybdenum-containing alloys, iron-containing alloys, tin-containing alloys, and other metal materials, or non-metallic conductive materials including carbon fiber filaments and graphite fiber filaments. It can also be a filament in which one or two of extremely fine conductive metal wires or conductive non-metallic wires are twisted together. The conductive metal wires and conductive non-metallic wires are relatively thin, and can be thin wires with a diameter of several microns to tens of microns, and there is no specific limitation.

Further, as shown in FIG9 , in other embodiments, the seam portion 1122 includes a first section 1122a, a third section 1122c, and a second section 1122b connected in sequence, the third section 1122c is located at the second side B, and the first section 1122a and the second section 1122b are respectively penetrated with the solid aerosol-forming matrix 111. When sewing, firstly penetrate the solid aerosol-forming matrix 111 from the first side A to the second side B, and then the first wire 1121 is led out along the second side B for a section and then penetrates the solid aerosol-forming matrix 111 to the first side A, and the first wire 1121 is sewn to the solid aerosol-forming matrix 111 in this cycle, so that both sides of the solid aerosol-forming matrix 111 can be heated, and the solid aerosol-forming matrix 111 is heated and atomized after the heating body 112 is heated. Of course, the length of the third section 1122c may be made shorter, and the line may not be routed on the second side B, but the second side B may be slightly exposed and return to the first side A along the sewing hole where the first section 1122a is located.

It can be understood that, as shown in FIG. 10 , the first wire 1121 can be bent, and the bending method can be back and forth bending or waveform bending. In addition, the wire can also be bent, and the bending method is not limited.

Furthermore, as shown in FIG11 , in order to make the heat radiation area larger, the heating body 112 includes a plurality of first wires 1121 located on the same side of the solid aerosol forming matrix 111. Preferably, the first wires 1121 may be two or more in number, and the first wires 1121 may be interwoven to form a mesh structure, or the first wires 1121 may be arranged side by side, or may be combined in an interwoven and side-by-side manner.

Preferably, in some embodiments, the heating body 112 further includes a flexible second wire 1124 sewn on the solid aerosol forming matrix 111, and the first wire 1121 and the second wire 1124 are respectively located on two opposite sides of the solid aerosol forming matrix 111, and the first wire 1121 and the second wire 1124 are interwoven with each other, so that the combination of the heating body 112 and the solid aerosol forming matrix 111 is more stable. Generally, the second wire 1124 can be made of insulating material, so that the side where the first wire 1121 of the heating body 112 is located is heated, the heating temperature rise speed is slowed down, the heating is evenly heated, and the local high temperature in the aerosol forming unit 10 is avoided to produce harmful substances. Of course, the second wire 1124 can also be made of conductive material, and the first wire 1121 and the second wire 1124 with smaller resistance can be selected to avoid too fast heating and too high temperature.

The sheet-like solid aerosol-forming matrix 111 is made of a material such as cloth or paper-like material made by extracting flavored plant fibers from herbs through a papermaking method or the like. It has a certain hygroscopicity and will produce an aerosol with a similar herbal flavor when heated. It can also be made by fully mixing some substances that are easy to produce smoke, such as propylene glycol, glycerol, and edible flavors into a solvent that can be atomized. The solvent and other substances are adsorbed into the herbal plant fibers. When the heat generated by the heating body 112 reaches the temperature required for solvent atomization, an aerosol is generated.

Since the first wire 1121 is relatively soft, the sheet-like solid aerosol-forming matrix 111 is equivalent to providing support strength for the wire. The heating body 112 and the aerosol-forming unit 10 are an integrated structure. The heat utilization rate of the heating body 112 is relatively high, so that the heated solid aerosol-forming matrix 111 can be well utilized and heated more fully. In addition, the aerosol-forming unit 10 is discarded after use, which avoids cleaning and damage to the power supply equipment compared to the piercing heating method. At the same time, the position and depth of the sewing are more uniform, making the heat generated more uniform, and the heated aerosol-forming unit 10 is heated evenly, avoiding local high temperature in the aerosol-forming unit 10 and the generation of harmful substances.

Preferably, as shown in FIG13 , both ends of the first wire 1121 are electrically connected with conductive electrodes 1131 respectively. In order to allow the heating body 112 to conduct heat in sections, further, as shown in FIG14 , the electrode 113 may also include one or more conductive electrodes 1131 connected between the two ends of the first wire 1121. By connecting the conductive electrodes 1131 at different positions, different sections of the heating body 112 can be involved in the heating. For example, the heating body 112 can be divided into an upper heating part and a lower heating part. When in use, the control circuit realizes heating in sections.

Further, as shown in FIG15 , the conductive electrode 1131 further includes an extension portion 1132 extending out of the solid aerosol-forming matrix 111. The extension portion 1132 is a sheet-shaped conductor that can be attached to the conductive electrode 1131 and extend outward, or the extension portion 1132 can be sewn and fixed when the conductive electrode 1131 is sewn. After the solid aerosol-forming matrix 111 is curled and folded, the extension portion 1132 can be wound around or bent onto the outer wall surface of the atomizing component 11a to facilitate contact with the heater 20. Of course, the extension portion 1132 can also be eliminated, and when the solid aerosol-forming matrix 111 is curled and folded, the area where the conductive electrode 1131 is located can be set on the outside.

As shown in Figures 3 and 16, when the conductive electrode 1131 extends out of the solid aerosol-forming matrix 111, the conductive electrode 1131 is led out from the side wall of the aerosol-forming unit 10 and is arranged along the circumference of the aerosol-forming unit 10. When the aerosol-forming unit 10 is inserted or placed on the heater 20, any turn can contact the contact point 211 on the heater 20.

Of course, as shown in Figures 17 and 18, in other embodiments, the conductive electrode 1131 can also be led out from the end of the aerosol forming unit 10 and then set at the end of the aerosol forming unit 10, or it can be led out from the end and bent to the side wall surface of the aerosol forming unit 10 to contact and conduct with the contact contact 211 at the corresponding position on the heater 20.

Preferably, in combination with FIGS. 13 and 14 , in this embodiment, the solid aerosol-forming matrix 111 includes a heating section 1111 and a coating section 1112, the heating body 112 is arranged in the heating section 1111, and the electrode 113 is located in the coating section 1112. When winding or folding, the coating section 1112 can be located in the outermost layer, covering the internally wound or folded heating section 1111, and the heat of the internal heating section 1111 can be transferred to the outer coating section 1112 to heat the atomized coating section 1112, without the heating body 112 directly heating the coating section 1112, so as to avoid excessively high temperature on the outside. Of course, in other embodiments, the heating section 1111 and the coating section 1112 may not be distinguished, and the heating body 112 may be distributed in various regions on the solid aerosol-forming matrix 111.

In some embodiments, the conductive electrode 1131 can be formed by sewing the first wire 1121 onto the solid aerosol-forming substrate 111, which is conducive to the mass and automated production of the atomization assembly 11a. It is understandable that part of the conductive electrode 1131 can also be woven onto the solid aerosol-forming substrate 111 using another conductive wire.

Furthermore, the two conductive electrodes 1131 are located on the same side of the solid aerosol forming matrix 111. Preferably, the conductive electrode 1131 and the first wire 1121 are the same conductive wire. The conductive electrode 1131 and the heating body 112 can be sewn at one time by one conductive wire, thereby improving production efficiency.

Of course, in other embodiments, one of the conductive electrodes 1131 may be located on the first side A, and the other conductive electrode 1131 may be located on the second side B. The conductive electrode 1131 located on the first side A may be the same conductive wire as the first wire 1121, and the conductive electrode 1131 located on the second side B may be sewn separately and contact and conduct with the wire located on the second side B of the heating body 112.

Furthermore, a conductive layer may be provided on the conductive electrode 1131 formed by sewing, so as to stabilize the resistance and facilitate external leads or contacts. In some embodiments, the conductive layer is formed by conductive paste or conductive glue, and the conductive glue or conductive paste may be coated or printed.

It can be understood that in other embodiments, the conductive layer can also be a metal sheet, which is attached to the conductive electrode 1131. The material of the metal sheet can be nickel, stainless steel, copper, aluminum foil, etc., and then the metal sheet is pierced by sewing and sewn to the solid aerosol forming matrix 111 to fix them together. The advantage of this is that the conductive electrode 1131 will have a certain hardness support, which can be more conveniently connected to the contact in the heater 20.

As shown in Figures 19 and 20, in some embodiments, the atomizing assembly 11a further includes a heat-conducting layer 114 for heat conduction, which is disposed on at least one side of the solid aerosol-forming substrate 111, and the heat-conducting layer 114 is made of an insulating material. The heat-conducting layer 114 and the solid aerosol-forming substrate 111 are fixed as a whole through the heating body 112, so that the heat generated by the heating body 112 can be evenly dispersed through the heat-conducting layer 114, rather than being concentrated in the part close to the heating body 112, so that each part of the solid aerosol-forming substrate 111 can be heated evenly, avoiding the situation where a part is heated and carbonized, while the other part is not heated and wasted.

In conjunction with FIGS. 5 and 6 , another embodiment of the present application further discloses a manufacturing process of an atomizing assembly 11a, comprising the following steps:

S11, providing a flexible solid aerosol-forming substrate 111 and a flexible first wire 1121, wherein the first wire 1121 is made of a conductive material;

S13 , disposing a conductive electrode 1131 electrically connected to the heating body 112 on the solid aerosol-forming substrate 111 .

In step S12 , when sewing the first wire 1121 , the first wire 1121 is passed from the first side A to the second side B and then returned to the first side A through the same sewing hole, so that the first wire 1121 forms a sewing portion embedded in the solid aerosol-forming matrix 111 .

When the first wire 1121 is sewn, at least one seam portion 1122 is formed, which passes from the first side A to the second side B opposite to the first side A and then returns to the first side A.

Of course, as shown in FIG. 9 , when sewing the first wire 1121, the first wire 1121 may also pass from the first side A to the second side B, then run along the second side B, and then pass to the first side A. The sewing method of the first wire 1121 on the solid aerosol-forming substrate 111 is not limited, and the first wire 1121 can be combined and fixed to the solid aerosol-forming substrate 111.

Further, in combination with what is shown in FIG. 12 , in some embodiments, step S12 further includes: providing a flexible second wire 1124, sewing the first wire 1121 and the second wire 1124 from both sides of the solid aerosol-forming matrix 111 respectively, and interweaving the first wire 1121 and the second wire 1124 to the solid aerosol-forming matrix 111 to form a heating body 112, wherein the heating body 112 after the first wire 1121 and the second wire 1124 are interwoven with the solid aerosol-forming matrix 111 is more stably combined.

In some embodiments, in step S13, one conductive electrode 1131 may be formed by sewing, or both conductive electrodes 1131 may be formed by sewing. In addition, a conductive layer is provided on the conductive electrode 1131 formed by sewing.
