Detailed ways

Below, the application is introduced.

First, the overall structure of the atomization system is illustrated in FIG. 1 . FIG. 1 is a schematic overall structural diagram of an embodiment of the atomization system provided by the present application. The atomization system includes a smoking article 100 made of a tobacco material, an atomizing assembly 200 for heating the smoking article 100 to generate smoke, and a battery rod assembly 300.

The specific structure of the atomization system will be described below with reference to FIGS. 2 and 3, wherein FIG. 2 and FIG. 3 are schematic cross-sectional views of the atomization assembly 200 with the smoking article 100 inserted under different sides.

The atomizing assembly 200 shown in this embodiment is internally provided with a receiving cavity 201. The inside of the receiving cavity 201 is inserted and fixed with an induction coil assembly 202. The induction coil assembly 202 is made of a conductive material.

Next, referring to the structural schematic view of an embodiment of the smoking article 100 shown in FIG. 4, the smoking article 100 is rolled from the smoking layer 101 and the heat generating layer 102.

In the axial direction of the smoking article 100, the first end portion and the second end portion of the heat generating layer 102 are electrically connected by a conductive member.

The conductive component can be made of the same material as the heat generating layer 102, or is formed into a strip-shaped heat generating layer 102, which is not limited herein. The heat generating layer 102 forms a conductive loop through the conductive component, and the smoke layer 101 is heated. The material is formed by a material that the user can smoke, and the heat generating layer 102 and the conductive component are made of an electrically conductive material.

It should be understood that, as shown in FIG. 4, the outermost layer of the smoking article 100 is the smoking layer 101. In practical applications, the outermost layer of the smoking article 100 may also be the heat generating layer 102, specifically not here. limited.

Moreover, as shown in FIG. 4, the number of turns of the smoking layer 101 and the heat generating layer 102 is 4 turns, and in practical applications, the number of turns of the rolled layer may be 2, 3, 5, or 6 turns. The number of laps is determined by the actual setting, and is not limited here.

In this embodiment, when the smoking article 100 is in the target state, the atomizing assembly 200 can heat the smoking article 100 based on the electromagnetic heating principle.

Specifically, the target state is that the smoking article 100 is inserted into the induction coil assembly 202 via the cavity 203 of the accommodating cavity 201, so that the smoking article 100 is inserted into the induction coil assembly 202, so that the diameter along the atomizing component is made. Toward, the heat generating layer 102 of the smoking article 100 is disposed opposite the induction coil assembly 202.

In order to achieve heating of the smoking article 100 by the electromagnetic induction heating principle, the battery rod assembly 300 shown in the present application is electrically connected to the induction coil assembly 202.

Specifically, the specific process of heating the smoking article 100 by the atomizing assembly 200 is described below:

When the user needs to smoke, the user can press the push switch 301 located on the battery rod assembly 300 as shown in FIG. 1. When the push switch 301 is pressed, the battery rod assembly 300 and the induction coil assembly 202 are electrically connected. Therefore, the battery rod assembly 300 is connected to the induction coil assembly 202 to input a high-frequency alternating current, and the high-frequency alternating current generates a high-frequency alternating magnetic field in the induction coil assembly 202. When the magnetic lines of the high-frequency alternating magnetic field pass through the heat-generating layer 102, A large amount of eddy current is generated inside the heat generating layer 102, so that the heat generating layer 102 generates a vortex heat effect to release a large amount of heat so that the heat generating layer 102 heats the simultaneously rolled smoke layer 101 to generate smoke, thereby enabling the user to smoke to smoke. The smoke generated by layer 101.

The heat generating layer 102 shown in this embodiment can not only heat the smoking article 100 based on the electromagnetic heating principle described above, but also the heat generating layer 102 can heat the smoking article 100 based on the principle of hysteresis loss, specifically, When the battery rod assembly 300 is connected to the induction coil assembly 202 with a high-frequency alternating current, the magnetic state of the heat-generating layer 102 changes under the action of the induction coil assembly 202, and the magnetization of the heat-generating layer 102 lags behind that of the induction coil assembly 202. The magnetic field strength, the hysteresis loss per unit volume of the heat generating layer 102 is proportional to the area of the hysteresis loop, and this portion of energy is converted into thermal energy, and the heat generating layer 102 heats the smoking article 100 based on the generated thermal energy.

The atomization system and the smoking article 100 provided by the present application generate an induced current on the heat generating layer 102 of the smoking article 100 and generate heat when the atomizing assembly is supplied with a high-frequency alternating current by the principle of electromagnetic induction heating, thereby achieving The heating of the smoking layer 101 of the smoking article 100 forms smoke for the user. Since the smoking article 100 is rolled from the heat generating layer 102 and the smoking layer 101, a large gap is formed between the heat generating layer 102 and the smoking layer 101. The contact surface, so that the heat generating layer 102 can achieve uniform heating of the smoke layer 101, so that the smoke formed by the smoking article 100 has no odor, and is more mellow, greatly avoiding the problem that the uneven heating causes the odor of the smoke.

It is worth mentioning that the atomization system and the smoking article 100 provided by the present application can achieve uniform heating of the smoking layer 101, that is, uniform heating of the smoking article 100, and can greatly avoid the heated tobacco. Material contamination problems.

It is easy to understand that in the existing atomization system, the heating part assembly needs to be inserted into the flue-cured tobacco branch, and the flue-cured tobacco branch is heated from the inside. When the flue-cured tobacco branch is heated, the tobacco material is liable to stick to the heating part assembly. On the other hand, when the user smokes the smoke, the cigarette smoke is not only blocked, but also the tobacco material sticks to the heating unit component and remains in the atomizing assembly 200, and the user needs to frequently clean it. It is inconvenient and it is not easy to clean up.

In the atomization system and the smoking article 100 provided by the present application, after the user smokes the smoke, the smoking article 100 can be directly pulled out, and since no heating component is inserted into the smoking article 100 for heating, There is a problem that the heating part assembly is adhered to the heated tobacco material, or the heating part assembly takes out the heated tobacco material in the smoking article 100 and remains in the atomizing assembly 200, and the user can easily pull out the smoking article 100. And there is no need to clean up frequently, which greatly improves the user experience.

Moreover, the smoking article 100 is disposable for use in this setting, and the user can directly discard the smoking article 100 after smoking the smoke, which is simple and convenient.

In an actual application, in order to further improve the user experience, the atomization system and the smoking article 100 provided by the present application also have various optimizations, as described in detail below.

In one possible implementation, the smoking layer 101 provided herein may comprise a tobacco sheet that is pressed from a tobacco material, or the tobacco material is made by a papermaking process. In practical applications, fibrous materials can also be added when making tobacco sheets.

It can be understood that when the tobacco sheet is produced by the papermaking process, the addition of the fiber material component contributes to the improvement of the toughness of the tobacco sheet, or can also be understood as characteristics such as ductility, tensile strength or tensile strength, so as to subsequently heat the tobacco sheet and heat. After the layer 102 is rolled together, the shaping effect of the smoking article 100 is promoted to make it more stable and less deformable in structure. Among them, the tobacco sheet is obtained through the papermaking process through the tobacco material and the fiber material, which not only facilitates the production and processing of the tobacco sheet, but also facilitates assembly in the smoking article 100, facilitates automation, standardized production, and improves the production of the smoking article 100. effectiveness.

In another possible implementation manner, the heat generating layer 102 may be one of a metal paper, a metal mesh, a metal film, and a metal foil. It is easy to understand, and a metal material with better conductivity can be used to make a paper shape. The mesh shape, the film shape or the foil shape facilitates the winding of the smoke layer 101, and the metal material is easy to be energized and heated to facilitate heating of the smoke layer 101.

The heat generating layer 102 can also be made of a material such as graphite.

In yet another possible implementation, the metal paper, the metal mesh, the metal film, and the metal foil are specifically made of at least one of aluminum, copper, silver, and gold.

It can be understood that the high-conductivity heat-generating layer 102 helps to improve the heating efficiency of the smoking article 100, that is, the high-conductivity heat-generating layer 102 generates a high-frequency alternating magnetic field when the induction coil assembly 202 passes a high-frequency alternating current to generate a high-frequency alternating magnetic field. A large amount of eddy currents can be generated more quickly, and heat is released to heat the smoke layer 101.

In practical applications, aluminum, copper, silver and gold have excellent electrical conductivity, which is convenient for processing on the process, especially aluminum and copper, and has the advantages of low cost, and is convenient for promoting the application of the smoking article 100 and Promotion.

The groove of the portion is arranged to provide a conductive strip in the groove; or the conductive strip may be disposed on the outer side of the smoking article 100, which is not limited herein.

Further, an insulating layer may be disposed on the peripheral wall of the conductive strip through insulation protection to ensure a stable flow of current on the conductive strip.

In yet another possible implementation, as mentioned above, the electrically conductive component is disposed between the first end and the second end of the heat generating layer 102. It can be understood that the first end portion and the second end portion of the heat generating layer 102 are respectively located at the third end portion and the fourth end portion of the smoking article 100.

In a practical application, the first end of the heat generating layer 102 may be specifically disposed on the inner side of the third end of the smoking article 100, and the second end of the heat generating layer 102 may be specifically disposed at the fourth end of the smoking article 100. The outside.

In this arrangement, the heat generating layer 102 forms the longest conductive loop with the conductive group assembly, so that the heat generating layer 102 can form the largest effective heating area for the smoke layer 101, so that the smoke layer 101 can be uniformly heated to form an odorless smoke. .

Of course, in a further possible implementation, the conductive component may also be disposed in the accommodating cavity 201 of the atomizing component 200. The conductive component may include two conductive members and a conductive line between the two conductive members, when the smoking article 100 When inserted into the induction coil assembly 202, the two conductive members can be electrically connected to the first end portion and the second end portion of the heat generating layer 102, respectively, thereby achieving the first end portion and the second end portion of the heat generating layer 102.

As shown in FIG. 5, after the smoke layer 101 and the heat generating layer 102 are laminated, they can be wound up to obtain the smoking article 100.

It should be understood that the specific description of the smoking layer 101, the heat generating layer 102, and the smoking article 100 can be referred to the above, and details are not described herein.

In addition, when the conductive component is a conductive strip, the method for manufacturing the smoking article 100 further includes:

Step 1003, electrically connecting the first end portion and the second end portion of the heat generating layer through the conductive component to form a conductive loop.

It should be understood that there is no timing limitation in step 1003 and step 1001 and step 1002. In actual application, step 103 may be performed simultaneously with step 1001 or step 1002, or may be performed before step 1001, or may also be in step 1002. After that, it is not limited here.

In summary, the atomization system and the smoking article 100 provided by the present application generate an induced current and generate heat on the heat generating layer 102 of the smoking article 100 when the atomizing assembly is supplied with a high-frequency alternating current by the principle of electromagnetic induction heating. Thereby, heating of the smoking layer 101 of the smoking article 100 is realized, and smoke is formed for the user. Since the smoking article 100 is rolled from the heat generating layer 102 and the smoking layer 101, uniform heating of the smoking layer 101 can be achieved. Therefore, the smoke formed by the smoking article 100 has no odor, and is more mellow, greatly avoiding the problem that the uneven heating causes the odor of the smoke.
