Definitions
- the present invention relates to a heating unit for an HNB tobacco article comprising a tobacco-containing material and an electrical resistance heating element for heating the tobacco-containing material without combustion.
- the invention also relates to a method for producing a heating unit for an HNB tobacco article.
- HNB tobacco article An alternative design of an HNB tobacco article is disclosed in WO 2013/131764 A1.
- smokable material such as a tobacco blend
- a heater is arranged, for example, a ceramic heater, an infrared or a resistance heater.
- the object of the invention is to provide a heating unit which allows a more uniform heating of the tobacco-containing material, as well as a method for producing the heating unit.
- the resistance heating element can be printed on the carrier material as a (heating) pattern (sample print).
- a uniform or homogeneous layer may be applied to the support material, in particular by printing or spraying, which is then applied in a second working process.
- the heating element preferably has a number of sections which can be electrically controlled individually, for example to produce different temperatures. Alternatively, for example, the sections may also be heated sequentially, for example to ensure continuity of consumption. For example, if a section matches the consumer experience of a cigarette, then a multi-cigarette product can be realized.
- FIG. 1 shows a schematic cross-sectional view of a HNB smoke product; an embodiment of a heating unit according to the invention for a HNB smoke product; a further embodiment of a heating unit for a HNB smoke product according to the invention; a layer system for a heating unit according to the invention; a tube layer structure for a heating unit according to the invention; another layer system for a heating unit according to the invention;
- the suspension or paste is applied during the production of the heating unit 13 to the carrier material 20 in a form which corresponds to the later heating element 18.
- the application of the suspension or paste to the carrier material 20 can advantageously be effected by printing, in particular screen printing, or by any other suitable method.
- the heating element 18 is formed on the carrier material 20 with the heating element 1 8 then the tobacco-containing material 26 is applied.
- the tobacco-containing material 26 may in particular be a tobacco mixture.
- the tobacco-containing material 26 is in direct contact with the heating element 18 and can be heated in a uniform manner.
- the electronic control 14 When the electronic control 14 suitably detects a pull by the consumer, it controls the heating element 18 in the heating unit 13 to heat the tobacco-containing material 26 to a suitable temperature. In this way, the aroma of tobacco without burning and harmful
- the heating conductor loops 21 advantageously form a plurality of sections 21 of the heating element 18, which are individually electrically controllable, for example to produce different temperatures.
- the sections 21 can be heated, for example, successively, for example, to ensure continuity in the smoke. If a section 21 corresponds, for example, to the smoking experience of a cigarette, a multi-cigarette product can be realized in this way.
- the heating element 18 is also present here as a conductive suspension or paste and is applied directly to the tobacco-containing material 26, for example by screen printing.
- the operation of applying the tobacco-containing material 26 to the carrier material 20 with heating element 18 can be dispensed with.
- a maximum overlap between tobacco-containing material 26 and heating element 8 is also ensured, a drop of tobacco material from the carrier material 20 is not possible.
- the heating unit 3 is a layer system with two carrier layers 20A, 20B, for example made of ceramic, between which the conductive view 18, such as graphite, is introduced. On the ceramic layer 20A, the tobacco-containing material 26 is applied.
