Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating element for generating an aerosol and a smoking device using the same,

The present invention relates to a heating element for generating an aerosol by heating a smoking article and a portable smoking apparatus using the same.

Cigarette burning directly produces harmful smoke components generated by combustion and pyrolysis degradation of cigarettes. Smoking articles which have been heated to reduce these harmful smoke components have been proposed. In a heated smoking article, an aerosol is generated by transferring heat to an aerosol-forming substrate or material. The volatile compounds released from the aerosol forming substrate by heat transfer from the heat source during smoking are mixed with the air sucked through the smoking article and condensed upon cooling to form an aerosol which is sucked into the smoker.

A number of prior art documents disclose smoking devices for heating such smoking articles to generate aerosols. Among these heating elements for heating the aerosol forming substrate, heat generating resistor patterns arranged in a plate-shaped insulating plate have been used. The blade heating resistor is inserted at the center of the smoking article to heat the surrounding aerosol forming substrate. At this time, the heat generating resistor pattern is disposed only on one surface of the insulating plate, and the whole of the heat generating resistor pattern is heated at the same time when a voltage is applied. At this time, the aerosol forming substrate adjacent to the one surface of the insulating plate on which the heat generating resistor pattern is disposed is appropriately heated to generate aerosol, but the aerosol forming substrate adjacent to the back surface has a problem that the insulating plate blocks heat and does not sufficiently heat. Further, since the entire heat generating resistor pattern is heated at once, the aerosol forming substrate is also heated as a whole, so that there is a problem that the taste is rapidly deteriorated after a certain period of time. You can not keep tobacco taste constant for single smoking articles.

A heating element for generating an aerosol to achieve the above-described object is disclosed. And the heating element includes a first group of heat generating resistors arranged side by side in the longitudinal direction of the smoking article and forming a plurality of heating regions capable of being driven separately from each other. According to this, the heating element can heat the aerosol-forming substrate at different timings along the length direction, and can provide a uniform taste of tobacco.

The first heat generating resistor group may be disposed on one surface of the insulating substrate.

The insulating substrate may include a second heat generating resistor group on the back surface thereof to uniformly heat the aerosol forming substrate as a whole.

The first heat generating resistor group and the second heat generating resistor group are connected to each other through the through holes of the insulating substrate, so that the heating area can be formed over a wide area.

A smoking device for aerosol generation is disclosed. A smoking device includes a heating element including a first group of heating resistors arranged side by side in the longitudinal direction of the smoking article and forming a plurality of heating regions capable of being driven separately from each other, a battery for supplying power to the heating element, And an electronic control unit for controlling the heating element.

Hereinafter, a smoking device 100 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a perspective view and a cross-sectional view respectively showing a smoking apparatus 100 according to an embodiment of the present invention. The smoking apparatus 100 includes a smoking unit 110, a power source unit 120, and an operation button unit 130. The smoking part 110 has an inlet at the end thereof for inserting the smoking article 10 therein. In the smoking part 110, a heating element 140 protrudes in the longitudinal direction. The smoking part 110 includes an electronic control part 150 for controlling the heating element 140. [

The smoking article 10 comprises a cylindrical shaped aerosol forming substrate 12, a cooling section 14 and a filter 16.

The aerosol forming substrate 12 is preferably an aerosol-forming substrate of solid or solid and liquid components. The aerosol forming substrate 12 is surrounded by paper or other wrapping material. The solid aerosol forming substrate may comprise one or more of powders, granules, pellets, slices, strands, strips or sheets containing, for example, one or more of herb leaves, tobacco leaves, tobacco ribs, expanded tobacco and homogenized tobacco have.

The aerosol forming substrate 12 may comprise nicotine. The aerosol forming substrate 12 preferably comprises a cigarette or a non-cigarette with an aerosol forming material.

The cooling portion 14 is located downstream of the aerosol forming substrate 12 to cool the aerosol evaporated by heating. The cooling portion 14 may comprise a getter sheet of material selected from the group consisting of a metal foil, a polymerizable material, and a substantially non-porous paper or paperboard. The cooling section 14 is formed from a group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA) And may include a separate sheet of material to be selected.

The filter 16 is the portion where the smoker smokes the cigarette on the mouth. The filter (16) is located adjacent to the downstream of the cooling section (14). The filter 14 may comprise a filter formed of acetate tow.

3, the heating element 140 includes a first group of heat generating resistors composed of three heat generating resistors AX, BX, and CX on an insulating plate 141.

The insulating plate 141 is made of a material such as ceramic, glass, epoxy, or polyimide.

The heat generating resistors AX, BX, and CX are disposed on the insulating plate 141 by a pressure-applying material such as tungsten by pressure application, printing, coating, or the like.

The heat generating resistor AX constitutes a first heating region 142 at the leading end side of the blade-type insulating plate 141. A positive voltage is applied to the lead wire A and a negative voltage is applied to the lead wire X. [ As a result, heat is generated by the resistances in the lead wires (A, X) and the first heating region 142.

The heat generating resistor BX constitutes the second heating region 144 after the first heating region 142. [ Alternatively, a positive voltage is applied to the lead wire B and a negative voltage is applied to the lead wire X. As a result, heat is generated by the resistances in the lead wires (B, X) and the second heating region 144.

The heat generating resistor CX constitutes the third heating region 146 after the second heating region 144. [ Alternatively, a positive voltage is applied to the lead wire C and a negative voltage is applied to the lead wire X. As a result, heat is generated by the resistances in the lead wires (C, X) and the third heating region (146).

The three heat generating resistors AX, BX and CX can be separately driven and simultaneously driven.

The three heating resistors AX, BX and CX first heat the third heating zone 146 to heat the aerosol forming substrate farthest from the filter 16, And the first heating zone 142 is heated after a predetermined time so that the new aerosol forming substrate is always heated during the entire smoking period so that the smoker can feel a uniform taste. Here, the sum of the predetermined time is the time when the smoker smokes using one smoking article, which may be set by the smoker. Of course, the smoking habit of the smoker can be automatically adjusted according to the situation, time, etc. through the big data. For example, after smokers are in the morning, they accumulate smoking time data after breakfast, during morning work, after lunch, during afternoon work, after dinner, before sleep, etc. and automatically adjust to the highest smoking frequency So that the heat generating resistors AX, BX and CX can be heated.

The positive voltage is applied to the leads A, B and C and the negative voltage is applied to the lead X as described above. On the other hand, a negative voltage is applied to the lead wires A, B and C, + Voltage may be applied.

Further, although the first heat generating resistor group has been described as including three heating regions 142, 144, and 146, it may be configured as two or four or more as necessary.

The insulating plate 141 may include a second heat generating resistor group (not shown) on its back surface. The second group of heat generating resistors can be arranged in the same manner as the first group of heat generating resistors and can operate synchronously. Of course, the second group of heating resistors may be arranged as different from the first group of heating resistors and operated asynchronously. Each of the heat generating resistors of the second heat generating resistor group may be connected to each heat generating resistor of the first heat generating resistor group by a conductive through hole passing through the insulating plate 141. In this case, it is possible to maximize the area of each of the plate surfaces of the insulating plate 141, thereby enlarging the area of the heating region.

As a modified embodiment, the heating element 140 may be formed in such a form that the insulating plate 141 is omitted and a plurality of heat generating resistors are insulated from each other, and the heat generating resistors are exposed on both sides.
