Referring to fig. 1, fig. 1 is a schematic flow chart of a heating efficiency control method for an rf heating smoking set according to an embodiment of the present application. In an embodiment of the present application, the method includes:
s101, when detecting that a cigarette is inserted, acquiring cigarette parameter information of the cigarette, wherein the cigarette parameter information comprises cigarette radius information and tobacco material information.
The execution body of the present application may be a controller of a smoking article.
In this application embodiment, the controller can measure and determine whether a cigarette is inserted in the smoking set by means of a photosensitive sensor or the like. After detecting that a cigarette is inserted, the controller firstly acquires the cigarette parameter information of the cigarette to determine the specific type of the cigarette and the related parameter data information of the cigarette of the type. The acquisition mode of cigarette parameter information can be realized by scanning two-dimensional codes and the like arranged on cigarettes.
S102, continuously shortening the distance between the polar plates in the radius range corresponding to the cigarette radius information, and detecting the temperature change rate of the cigarette in unit time.
In this application embodiment, because the section of being fuming warp comparatively easily in the cigarette props up, so the smoking set even cigarette inserts the back, the polar plate of centre gripping cigarette can also further shorten the interval to this improves electric field strength. Although under the unchangeable condition of polar plate voltage, shorten the polar plate interval and just can improve electric field strength, but the structure of cigarette has decided the polar plate interval and can only shorten cigarette radial distance at most, and because cigarette its electric capacity structure also will change in deformation process for it is not that the more high that the heating efficiency is more that the less of polar plate interval is. Therefore, the controller can continuously shorten and adjust the distance between the polar plates in the radius range corresponding to the cigarette radius information so as to continuously detect the temperature change rate of the cigarette in different polar plate distances. The higher the rate of temperature change, the more efficient the heating of the tobacco rod can be considered.
In one possible embodiment, step S102 includes:
acquiring the current temperature of the cigarette, and determining the target temperature corresponding to the tobacco material information;
calculating the temperature difference value between the current temperature and the target temperature of the cigarette, and determining a radius adjustment parameter according to the temperature range corresponding to the temperature difference value;
and in the radius range corresponding to the cigarette radius information, the preset duration is based on the radius adjustment parameter to shorten the distance between the polar plates, and the temperature change rate of the cigarette in unit time is detected.
In the embodiment of the application, the target temperature to which the tobacco rod needs to be heated is different according to the tobacco material in the tobacco rod. Therefore, the controller can determine the target temperature of the cigarette to be heated according to the tobacco material information and collect and determine the current temperature of the cigarette. The controller is preset with a plurality of temperature ranges, and different temperature ranges correspond to different radius adjustment parameters, so that the controller determines the radius adjustment parameters corresponding to the calculated temperature difference value, and the radius adjustment parameters are used as the standard for adjusting the distance between the polar plates every time to shorten the distance between the polar plates, and further determine the temperature change rate.
In one embodiment, the larger the temperature difference, the larger the radius adjustment parameter.
In the embodiment of the application, when the temperature difference is larger, that is, the current temperature of the cigarette is far away from the temperature capable of better precipitating aerosol, the heating efficiency is considered, and the temperature needs to be increased more quickly. In addition, under the condition that the distance between the polar plates is reduced, the general variation trend of the electric field intensity is increased, so that the radius adjusting parameter corresponding to the temperature range to which the temperature difference value belongs is larger when the temperature difference value is larger, the variation range of the electric field intensity is larger each time, and the electric field can be heated to the target temperature more quickly.
For example, when the radius adjustment parameter is 2mm, if the radius range is 0-20mm, the plate distance will change according to the trend of 20mm, 18mm and 16mm … every time a preset time period (for example, 30 s) elapses, and the controller will calculate the temperature change rate of a cigarette in unit time every time the plate distance changes, so as to compare the temperature change rate corresponding to each plate distance in the following.
In one possible embodiment, the detecting the temperature change rate of the cigarette in unit time includes:
and calculating the temperature change value of the cigarette in the preset time length, and calculating the ratio of the temperature change value to the preset time length, wherein the ratio is the temperature change rate.
In the embodiment of the application, the controller calculates the temperature change value of the cigarette in the preset time period by taking the preset time period as a period, and divides the temperature change value by the preset time period to obtain a ratio which is the temperature change rate in unit time.
S103, determining the target inter-polar plate distance when the temperature change rate is highest, and adjusting the current inter-polar plate distance to the target inter-polar plate distance.
In the embodiment of the application, the controller determines the inter-plate distance corresponding to the temperature change rate with the highest value among the temperature change rates detected in the previous step, takes the inter-plate distance as the target inter-plate distance, and adjusts the current inter-plate distance to the target inter-plate distance to ensure that the heating efficiency of the inserted cigarette is optimal.
In one possible embodiment, the cigarette parameter information further includes tobacco density information;
the determining the target inter-plate distance when the temperature change rate is highest comprises:
calculating the minimum deformation area of the cigarette based on the tobacco density information, and determining the first polar plate distance corresponding to the minimum deformation area;
determining a second plate spacing at which the rate of temperature change is highest;
when the second plate interval is not smaller than the first plate interval, taking the second plate interval as a target plate interval;
and when the second plate interval is smaller than the first plate interval, taking the first plate interval as a target plate interval.
In the embodiment of the application, in the process that the cigarette is extruded by the polar plate, the capacitance structure between the polar plates can be influenced, and the density degree of the tobacco in the cigarette can be changed due to the change of the cross section area of the cigarette. If the extrusion is too severe, the tobacco material in the tobacco is too dense, which results in poor air flowability, and thus, the user is very labored in smoking, which affects the user experience. The smaller the plate pitch is, the better. Therefore, the controller firstly needs to determine the minimum deformation area of the cigarette of the type according to the tobacco density information. The minimum deformation area can be determined by a manufacturer through a large number of data tests in the cigarette production design stage. After the minimum deformation area is obtained, the first polar plate distance corresponding to the minimum deformation area can be determined, the first polar plate distance is the minimum distance at which the cigarettes can be extruded, and if the polar plate distance is smaller than the first polar plate distance, the mobility of gas in the cigarettes is poor, and the cigarettes are difficult to suck. The controller compares the first plate interval with the second plate interval, and if the second plate interval is not smaller than the first plate interval, the second plate interval is directly used as the target plate interval. If the second plate spacing is smaller than the first plate spacing, the controller will choose to sacrifice a portion of the heating efficiency to ensure the user's pumping experience, with the first plate spacing as the target plate spacing.
In one embodiment, the method further comprises:
and constructing an incidence relation between the cigarette parameter information and the target polar plate distance, and calling the target polar plate distance based on the incidence relation when the cigarette parameter information is detected again.
In the embodiment of the application, after the target polar plate distance is determined, the controller can associate cigarette parameter information with the target polar plate distance and store the association relation, so that when the cigarette corresponding to the cigarette parameter information is inserted in the next re-detection, the cigarette can be directly adjusted based on the target polar plate distance, and the heating efficiency is further improved.
