Description

A segmented temperature control smoking set heating method, device and electronic equipment

Technical field

The present application relates to the technical field of heating control of smoking articles, and specifically, to a method, device and electronic equipment for heating smoking articles with segmented temperature control.

Background technique

High-frequency electric field heating is a form of dielectric heating of smoking articles. This form of heating has greater advantages than traditional heating methods (including conduction heating) because the main body of the tobacco material is heated directly without the need for surface heating. The heat is conducted from the outside in through the temperature gradient, which significantly reduces the possibility of unnecessary overheating or even scorching of the surface.

However, there is an edge effect when applying high-frequency electric field heating. The magnetic field distribution is strong at the edges and more average in the middle. Since the edges are attracted by the strong magnetic field, they show high energy density. This energy density is redistributed at the ends. The heating temperature at the end is increased. As a result, the temperature at the end is higher than the temperature in the middle part. There is an obvious temperature gradient in the longitudinal direction. The temperature distribution of the heated tobacco is uneven, which in turn affects the effect of aerosol precipitation in the cigarette and brings problems to the user. Poor suction experience.

Referring to Figure 1, Figure 1 is a schematic flow chart of a segmented temperature control smoking article heating method provided by an embodiment of the present application. In the embodiment of this application, the method includes:

S101. Divide the cigarette to be smoked into at least two cigarette segments so that each cigarette segment matches each plate heating segment in the smoking set.

The execution subject of this application may be the controller of the smoking device.

In this embodiment of the present application, the left and right electrode plates used to generate electric fields inside the smoking device will be divided into several sections, so that the distance between each section of the electrode plates can be adjusted individually, and each section of the electrode plates is a plate heating section. After the cigarette to be smoked is inserted into the smoking article, the controller will divide the overall length of the cigarette to be smoked into several cigarette segments according to the division of the heating sections of the electrodes, so that each cigarette segment can be matched with one The polar plate heating sections are matched so that each cigarette section can have a corresponding polar plate heating section to control the temperature of that part.

In an implementation manner, step S101 includes:

Determine a first number of pole plate heating sections in the smoking set, and divide the cigarette to be smoked into at least two cigarette sections based on the first number, so that each cigarette section is consistent with each of the pole plate heating sections. One match.

In this embodiment of the present application, the controller first determines the first number of pole plate heating sections, that is, determines how many pole plate heating sections there are in total, and then divides the cigarette sections according to the first number, so that the divided cigarette sections The number of branch segments is also the first number, so that the divided cigarette branch segments and the polar plate heating segments can be matched one-to-one.

S102. Detect the segment temperature of each cigarette segment respectively, and construct a cigarette temperature gradient curve based on the segment temperature.

In the embodiment of the present application, the section temperature can be understood as the temperature of the cigarette section detected by the temperature measurement unit attached to the inner wall of the smoking article. The temperature sensing element included in the temperature measurement unit can be a point contact of a thermocouple, or a surface contact of a fluorescent temperature sensing coating, etc.

In the embodiment of the present application, after dividing the cigarette segments, the controller will detect the segment temperature of each cigarette segment respectively, thereby constructing a cigarette temperature gradient curve based on the detected segment temperatures, thereby facilitating Subsequently, the temperature gradient changes of the cigarette during the heating process are judged.

In an implementation manner, constructing a cigarette temperature gradient curve based on the temperature of each of the paragraphs includes:

The position arrangement information of each of the cigarette segments is determined, and the temperature of each of the segments is combined based on the position arrangement information to obtain a cigarette temperature gradient curve.

In the embodiment of this application, in order to quickly determine which plate heating section is abnormal after subsequent analysis of the cigarette temperature gradient curve, during the construction process of the cigarette temperature gradient curve, each cigarette section will be The positional arrangement information determines the positional relationship of each cigarette segment, and then combines the segment temperatures to finally obtain the cigarette temperature gradient curve.

S103. Analyze the cigarette temperature gradient curve. When there is a sudden change in the cigarette temperature gradient curve, determine the target plate heating section corresponding to the sudden change, and regulate the plate spacing of the target plate heating section until the There are no sudden changes in the cigarette temperature gradient curve.

In the embodiment of the present application, by analyzing the temperature gradient curve of the cigarette, the controller can identify the mutation part in the temperature gradient curve of the cigarette. If there is a sudden change in the curve, it means that there is a significant longitudinal temperature gradient in this part, which will cause the local temperature in this part to be too high. Therefore, the controller will determine the position of the mutation at this time, and then determine which plate heating section needs to be controlled by the electric field intensity, that is, determine the target plate heating section, and then adjust the plate of the target plate heating section by controlling the smoking device. The electric field intensity is adjusted by adjusting the spacing to reduce the heating temperature of this part until there is no longer a sudden change in the curve, ensuring uniform temperature distribution in the cut tobacco section.

Determine the target plate heating section corresponding to the mutation curve segment, and regulate the electrode plate spacing of the target electrode plate heating section until there is no mutation in the cigarette temperature gradient curve.

In the embodiment of the present application, since the cigarette temperature gradient curve is formed based on the segment temperature, if the tobacco in the cigarette is in a uniformly heated state, the overall trend of the curve should be gentle, and when the cigarette is heated unevenly, The changing trend of the curve will also see a large vertical mutation. Therefore, when the controller analyzes the curve, it uses the slope of each point on the curve as the basis for judgment. When there is a curve segment with a slope greater than the preset slope, it is considered that there is a sudden change. At this time, the controller will determine the target plate heating section corresponding to the sudden mutation curve segment, and thereby adjust the plate spacing corresponding to the target plate heating section, thereby achieving heating of this section of the cigarette. The temperature is adjusted and finally adjusted until there are no more sudden changes in the cigarette temperature gradient curve.

The electrode plate spacing adjustment difference is calculated based on the electric field adjustment difference, and the electrode plate spacing of the target electrode plate heating section is adjusted according to the electrode plate spacing adjustment difference until there is no sudden curve segment in the cigarette temperature gradient curve. .

In the embodiment of this application, the controller will first determine the heating temperature of the target plate heating section that needs to be controlled, that is, the target section temperature, and average the temperatures of other normal sections to obtain the average temperature. The controller will Use the average temperature as the temperature to which the target segment temperature is ultimately expected to be adjusted. Specifically, since the heating temperature is affected by the electric field strength, and through a large number of data tests during the design stage of the smoking device, the controller will be able to store the corresponding relationship between the heating temperature and the electric field strength. Through this correspondence, the controller can calculate from the average The temperature difference between the temperature and the target section temperature is used to calculate the electric field adjustment difference that needs to be adjusted. In order to ensure that the electric field strength of other parts does not change, the voltage of the electrode plates cannot be adjusted. Therefore, the electric field intensity will be adjusted by adjusting the electrode plate spacing. Finally, the plate spacing adjustment difference that needs to be adjusted can be calculated. value, the controller will adjust the plate spacing based on the plate spacing adjustment difference until there is no sudden curve segment in the cigarette temperature gradient curve.

In an implementation manner, the step of regulating the pad spacing of the target pad heating section according to the pad spacing adjustment difference includes:

Generate a plate control instruction based on the plate spacing adjustment difference, and send the plate control instruction to the target plate heating section to control the target plate heating section according to the plate spacing adjustment difference. The value changes the plate spacing.
