Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
As shown in fig. 1, the smoking device of the present invention includes a heater 1 and a power supply 2, the heater 1 and the power supply 2 are connected by a control device 3, and the power supply 2 supplies power to the heater 1 by the control device 3. The control means 3 comprise an electronic circuit for controlling the power delivered to the heater 1, enabling power regulation of the heater 1 based on a detected feedback to the heater 1. Wherein the control means 3 detect that the resistance value of the heater 1 has increased in a transitional manner, the control means 3 obtains a first signal that the heating of the tobacco product (the term "tobacco product" relates to a finished product comprising tobacco material, in the present invention specifically a consumable finished product comprising tobacco material that matches the smoking means) is completed (to a smoking temperature) and reduces or stops the power transmission to the heater 1 in dependence of the first signal. This is because the increase in the resistance value of the heater 1 is directly related to the curie temperature of the heater 1, and when the curie temperature of the heater 1 is set to the operating temperature (smoking temperature) of the tobacco product, the control device 3 that directly or indirectly detects the resistance value of the heater 1 can obtain the first signal that the tobacco product is heated in time. Like this, the heating effect of heater 1 can be feedback in time as temperature probe to heater 1 to can realize the accurate accuse temperature of heater 1, heating efficiency is high, and the heating effect is good.
Preferably, when the control device 3 detects an increase in the resistance value of the heater 1, it is possible to appropriately delay the time for which the power transmission to the heater 1 is reduced or stopped.
In a specific embodiment, as shown in fig. 2-4, the heater 1 comprises a hollow tubular electrically conductive substrate 11, the interior of the electrically conductive substrate 11 being adapted to receive a smoking segment 4 of a tobacco article (as shown in fig. 1, the term "smoking segment of a tobacco article" relates to the smoking segment of a tobacco article above, the smoking segment of a tobacco article comprising a substance that upon heating releases tobacco-flavored smoke). The conductive substrate 11 is provided on its inner and/or outer surface with a heating layer 12 for heating the smoking section 4 of the tobacco product after being energized. The conductive substrate 11 and/or the heating layer 12 are provided with a plurality of electrical contacts 13 for connecting to an external power source 2, and the electrical contacts 13 form conductive paths capable of controlling voltage or current with the heating layer 12 and the conductive substrate 11 respectively by communicating with the power source. Wherein the resistance value of the conductive substrate 11 is larger than the resistance value of the heating layer 12. When the temperature of the conductive substrate 11 is lower than the curie temperature, the resistance value of the conductive substrate 11 increases gradually with an increase in temperature (the resistance value of the conductive substrate 11 changes gradually with temperature), and when the temperature of the conductive substrate 11 increases to a temperature higher than the curie temperature, the resistance value of the conductive substrate 11 increases in transition. So that the conductive substrate 11 can be used as a temperature detector to timely feed back the heating effect of the heater 1. In use, the electrically conductive substrate 11 and the heating layer 12 together heat the tobacco product after the electrical contacts 13 are connected to the power source 2. The conductive substrate 11 generates a certain amount of heat after being energized, which is labeled heat a. Heat is also generated by energizing the heating layer 12, which is labeled heat B. Since the resistance value of the conductive substrate 11 is greater than the resistance value of the heating layer 12, and when the temperature of the conductive substrate 11 is below the curie temperature, the resistance value of the conductive substrate 11 increases slowly with the increase in temperature, and when the temperature of the conductive substrate 11 increases above the curie temperature, the resistance value of the conductive substrate 11 increases in transition, resulting in heat a being much smaller than heat B, and therefore heat B generated by the heating layer 12 is a major factor in heating tobacco products.
In a particular embodiment, the curie temperature of the electrically conductive substrate 11 is the operating temperature of the smoking segment 4 of the tobacco article.
In one embodiment, the curie temperature of the conductive substrate 11 is 200 to 400 degrees celsius.

The different conductive strips 121 may be made of different materials or the same material. The plurality of conductive strips 121 may be stacked upon one another to achieve a composite electrical performance. For example, a first conductive strip may be partially superimposed on top of or below other conductive strips, with different conductive strips 121 forming the heating layer 12 in series or parallel.

In a particular embodiment, the outer surface of the heating layer 12 is coated with a first inert layer 14 for preventing oxidation of the heating layer 12. The first inert layer 14 is capable of protecting the heating layer 12 from oxidation.
In a specific embodiment, the outer surface and/or the inner surface of the conductive matrix 11 is provided with a second inert layer for preventing oxidation of the conductive matrix 11. Specifically, the conductive substrate 11 may be made of an air oxidation-resistant metal oxide, and although the conductive substrate 11 is oxidized by air at a slower rate than the heating layer 12, a second inert layer for preventing oxidation of the conductive substrate 11 may be provided on the outer surface and/or the inner surface of the conductive substrate 11 to protect the outer surface and/or the inner surface of the conductive substrate 11 in consideration of a convenient and quick manufacturing process.
In a preferred embodiment, the heating layer 12 is provided on the outer surface of the conductive substrate 11.
