[0029] In order to more clearly illustrate the specific embodiments of the present invention, the drawings required for use in the embodiments are briefly introduced below.

[0030] Figure 1 It is a schematic diagram of a cigarette identification method for a heat-not-burn smoking device provided by the present invention.

[0031] Figure 2 It is a schematic diagram of the airflow suction of a cigarette in a heating chamber provided by an embodiment of the present invention.

[0032] Figure 3 It is a schematic structural diagram of a mounting base provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0033] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0034] In view of the problem that current heat-not-burn smoking devices cannot identify the type of cigarettes and thus control the heating temperature of the cigarettes, the present invention provides a cigarette identification method and system for heat-not-burn smoking devices, which solves the problem that existing heat-not-burn smoking devices cannot accurately identify the type of cigarettes and thus control the heating temperature of the cigarettes when smoking different cigarettes. The method can improve the intelligence of the heat-not-burn smoking devices, enhance the user experience, and improve the user's smoking taste.

[0035] like Figure 1 and Figure 2 As shown, a cigarette identification method for a heat-not-burn smoking device comprises:

[0036] S1: A flow detection device is provided at the air inlet passage of the base of the cigarette heating chamber of the heat-not-burn tobacco device to collect the suction air flow through the bottom of the NSC cigarette or the universal cigarette in the heating chamber when it is smoked.

[0037] S2: Calculate the corresponding cigarette suction resistance and cigarette suction pressure according to the suction air flow rate.

[0038] S3: Set the correspondence between cigarette type and cigarette suction resistance or cigarette suction pressure.

[0039] S4: Determine whether the smoked cigarette is a NSC cigarette or a universal cigarette according to the corresponding relationship and the inhaled air flow rate.

[0040] In actual applications, since NSC cigarettes are sucked by negative pressure through the holes on the cigarettes, and the universal cigarettes are sucked by bottom air intake, the diameter of the universal cigarettes is larger than that of the NSC cigarettes. When using the same smoking device, the NSC cigarettes are thinner, and the airflow channel can be sucked through the holes of the NSC cigarettes during suction. When sucking, the suction resistance of the NSC cigarettes is greater than that of the universal cigarettes, and the suction pressure of the NSC cigarettes is greater than the suction pressure of the universal cigarettes. The method detects the suction air flow at the bottom of the heating chamber through a flow detection device, determines the corresponding cigarette suction resistance and cigarette suction pressure according to the suction air flow, and judges that the cigarette is an NSC cigarette when the cigarette suction resistance and cigarette suction pressure are greater than the corresponding threshold value, otherwise it is a universal cigarette, and then the corresponding temperature heating curve can be selected according to the type of cigarette to heat the cigarette. The method can accurately identify the type of cigarette, and then control the problem of cigarette heating temperature, can improve the intelligence of heat-not-burn cigarettes, increase the user experience, and improve the user's smoking taste.

[0041] The method further includes:

[0042] S5: Match the cigarette types with the cigarette heating temperature curves one by one.

[0043] S6: Determine a corresponding cigarette heating temperature curve according to the cigarette type, and heat the cigarette in the heating chamber according to the cigarette heating temperature curve.

[0044] Specifically, the heating temperature curves required for NSC cigarettes and wildcard cigarettes are set, and different heating temperature curves are used to heat the cigarettes according to different cigarette types. The airflow required for NSC cigarettes is less than that required for wildcard cigarettes, and correspondingly, the temperature required for heating NSC cigarettes is lower than that required for wildcard cigarettes.

[0045] Further, the step of determining the corresponding cigarette heating temperature curve according to the cigarette type includes:

[0046] If the cigarette being smoked is identified as an NSC cigarette, the NSC cigarette heating temperature curve is used to heat the cigarette.

[0047] If the cigarette being smoked is identified as a wildcard cigarette, the wildcard cigarette heating temperature curve is used to heat the cigarette, wherein the temperature corresponding to the NSC cigarette heating temperature curve is lower than the temperature corresponding to the wildcard cigarette heating temperature curve.

[0048] It can be seen that the present invention provides a cigarette identification method for heat-not-burn smoking devices, which determines the type of cigarette by the air flow rate of the cigarette in the heating chamber, and selects the corresponding heating temperature curve according to the type of cigarette to heat the cigarette in the heating chamber. This solves the problem that the existing heat-not-burn smoking devices cannot accurately identify the type of cigarette when smoking different cigarettes, and then control the heating temperature of the cigarette, which can improve the intelligence of the heat-not-burn smoking devices, increase the user experience, and improve the user's smoking taste.

[0049] Accordingly, if Figure 2 and Figure 3 As shown, the present invention also provides a cigarette identification system for heat-not-burn tobacco products, using the above-mentioned cigarette identification method, including: a control unit, a heating component 1 and a flow detection device. The heating component 1 is provided with a cigarette heating chamber, and the flow detection device is arranged at the bottom of the heating chamber. The control unit is respectively connected to the heating component and the flow detection device by signal, and the control unit controls the heating power of the heating component 1 according to the suction air flow through the bottom of the cigarette collected by the flow detection device, so as to heat the cigarette 3.

[0050] Furthermore, an air inlet passage extending from bottom to top is provided at the bottom of the heating chamber.

[0051] Furthermore, the air inlet passage is located at the center of the heating chamber.

[0052] Furthermore, the system also includes: a mounting base 2; an air hole is provided in the mounting base 2, the flow detection device is arranged in the air hole, and when the mounting base is plugged into the bottom of the heating chamber 1, the air hole is connected to the air inlet channel.

[0053] In practical applications, such as Figure 3 As shown, the front cover and the cavity of the mounting base 2 are provided with air holes correspondingly, and the flow detection device can be installed in the cavity. The front cover is a flat plate structure, and the cavity is a cylindrical structure.

[0054] Furthermore, the control unit includes: an MCU and a temperature sensor; the MCU is respectively connected to the flow detection device and the temperature sensor signal, and the temperature sensor is used to detect the temperature of the heating component in the heating chamber; the MCU controls the heating power of the heating component according to the temperature of the heating component.

[0055] Furthermore, the flow detection device adopts an air flow sensor or an air pressure sensor.

[0056] Furthermore, the heating chamber is heated by electromagnetic, infrared, MESH or thick film.

[0057] It can be seen that the present invention provides a cigarette identification system for heat-not-burn smoking devices, which determines the type of cigarette by the air flow rate of the cigarette in the heating chamber, and selects the corresponding heating temperature curve according to the type of cigarette to heat the cigarette in the heating chamber. This solves the problem that when different cigarettes are smoked by existing heat-not-burn smoking devices, the type of cigarette cannot be accurately identified, and the heating temperature of the cigarette cannot be controlled. It can improve the intelligence of the heat-not-burn smoking device, increase the user experience, and improve the user's smoking taste.

[0058] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
