Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a heating method for a segmented temperature control smoking appliance provided in 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 sections, so as to match each of the cigarette sections with each plate heating section in the smoking appliance.

The subject of execution of this application may be a controller of a smoking appliance.

In the embodiment of the present application, the left and right pole plates used to generate the electric field inside the smoking appliance are divided into several sections, so that the distance between each section of the pole plates can be individually adjusted, and each section of the pole plates is a plate heating section. After the cigarette to be smoked is inserted into the inside of the smoking set, the controller will divide the overall length of the cigarette to be smoked into several cigarette sections according to the division of the plate heating section, so that each cigarette section can be connected with a The plate heating section is matched, so that each section of cigarette branch can have a corresponding plate heating section to regulate the temperature of this part.

In a possible implementation manner, step S101 includes:

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

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

In the embodiment of the present application, the segment temperature can be understood as the temperature of the segment of the cigarette branch detected by the temperature measuring unit attached to the inner wall of the smoking appliance. The temperature-sensing element included in the temperature-measuring unit may 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 branch sections, the controller will detect the section temperature of each cigarette branch section respectively, so as to construct the temperature gradient curve of the cigarette branch according to the detected temperature of each section, so as to facilitate Subsequently, the temperature gradient change of the cigarette during the heating process is judged.

In a possible implementation manner, the construction of the cigarette temperature gradient curve based on the temperature of each section includes:

In the embodiment of this application, in order to quickly determine which segment of the plate heating section is abnormal after analyzing the temperature gradient curve of the cigarette branch, in the process of constructing the temperature gradient curve of the cigarette branch, the The position arrangement information of each cigarette branch determines the positional relationship of each segment, and then combines the temperature of the segments based on this, and finally obtains the temperature gradient curve of the cigarette branch.

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

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

In a possible implementation manner, step S103 includes:

In the embodiment of this application, since the temperature gradient curve of the cigarette is formed according to the temperature of the paragraph, if the tobacco in the cigarette is in a uniform heating state, the overall trend of the curve should be gentle, and when the heating of the cigarette is uneven, The change trend of the curve will also have a large vertical abrupt change. Therefore, when the controller analyzes the curve, the slope of each point on the curve is used as the judgment basis. When there is a curve segment whose slope is 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 change curve section, so as to adjust the plate spacing corresponding to the target plate heating section, and then realize the heating of this section of the cigarette The temperature is regulated, and finally adjusted until there is no sudden change in the temperature gradient curve of the cigarette.

In a possible implementation, the determination of the target plate heating segment corresponding to the sudden change curve segment, and adjusting the plate spacing of the target plate heating segment until there is no sudden change in the temperature gradient curve of the cigarette, includes:

Determine the target plate heating segment corresponding to the abrupt change curve segment, and determine the target segment temperature corresponding to the target plate heating segment;

Specifically, since the heating temperature is affected by the intensity of the electric field, the controller will be able to store the corresponding relationship between the heating temperature and the intensity of the electric field through a large number of data experiments in the design stage of the smoking appliance. The temperature difference between the temperature and the temperature of the target section is used to calculate the electric field adjustment difference that needs to be adjusted. In order to ensure that the electric field intensity of other parts will not change, the voltage of the plates cannot be adjusted, so the electric field intensity will be adjusted by adjusting the plate spacing, and finally the adjustment difference of the plate spacing 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 abrupt curve segment in the cigarette temperature gradient curve.

In a possible implementation manner, the adjustment and control of the pole plate distance of the target pole plate heating section according to the pole plate distance adjustment difference includes:

In the embodiment of the present application, the controller will generate a plate control command, and after the plate part corresponding to the target plate heating section receives the command, the telescopic device corresponding to the plate part will adjust the difference according to the distance between the plates Control to adjust the spacing of the plates.
