Description

Technical Field

[0001] The present application relates to the technical field of heating control of smoking articles, and in particular to a heating efficiency control method, device and electronic equipment for radio frequency heating smoking articles. Background Art

[0002] High-frequency electric field heating is a form of dielectric heating of smoking tools. This form of heating has great advantages over traditional heating methods (including conduction heating) because the main body of the tobacco material is heated directly without the need for the surface to be heated and then conduct the heat from the outside to the inside through a temperature gradient. This significantly reduces the possibility of unnecessary overheating or even burning of the surface.

[0003] How to improve the heating efficiency of the internal heating process of the cigarette has always been a key issue for researchers. Without changing the internal circuit of the cigarette to increase the voltage and frequency, the electric field strength is generally increased by reducing the spacing between the plates used to generate the electric field, so that the temperature change of the heating body such as tobacco is accelerated, thereby improving the heating efficiency. However, for different types of cigarettes, the cigarette radius and the type of tobacco material are different. The general heating control method of reducing the distance between the plates by a fixed distance during the heating process cannot adapt to different types of cigarettes. As a result, although the distance between the plates is shortened in actual use, the optimal heating efficiency is not achieved. Summary of the invention

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

[0037] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present application. Various processes or components may be appropriately omitted, substituted or added to each example.

In addition, features described in some examples may be combined in other examples.

[0038] See also Figure 1 , Figure 1 : is a flow chart of a method for controlling the heating efficiency of a radio frequency heating smoking device provided in an embodiment of the present application. In the embodiment of the present application, the method includes:

[0039] S101. When a cigarette insertion is detected, cigarette parameter information of the cigarette is obtained, wherein the cigarette parameter information includes cigarette radius information and tobacco material information.

[0040] The executor of the present application may be a controller of the smoking device.

[0041] In the embodiment of the present application, the controller can measure and determine whether a cigarette is inserted into the smoking device by means of a photosensitive sensor or the like. After detecting that a cigarette is inserted, the controller first obtains the cigarette parameter information of the cigarette to determine the specific type of the cigarette and the relevant parameter data information of the type of cigarette. The cigarette parameter information can be obtained by scanning a QR code set on the cigarette or the like.

[0042] S102, continuously shortening the distance between the plates within a radius range corresponding to the cigarette radius information, and detecting the temperature change rate of the cigarette per unit time.

[0043] In the embodiment of the present application, since the smoking section in the cigarette is relatively easy to deform, the distance between the plates holding the cigarette can be further shortened even after the cigarette is inserted, thereby increasing the electric field strength. Although the electric field strength can be increased by shortening the distance between the plates when the plate voltage remains unchanged, the structure of the cigarette determines that the distance between the plates can only be shortened by the radius of the cigarette at most, and since the capacitance structure of the cigarette will also change during the deformation process, the actual situation is not the case that the smaller the distance between the plates, the higher the heating efficiency. Therefore, the controller will continuously shorten and adjust the distance between the plates within the radius corresponding to the cigarette radius information, so as to continuously detect the temperature change rate of the cigarette at different plate distances. The higher the temperature change rate, the higher the heating efficiency of the cigarette.

[0044] In one possible implementation, step S102 includes:

[0045] Collecting the current temperature of the cigarette and determining the target temperature corresponding to the tobacco material information;

[0046] Calculating the temperature difference between the current temperature of the cigarette and the target temperature, and determining the radius adjustment parameter according to the temperature range corresponding to the temperature difference;

[0047] Within the radius range corresponding to the cigarette radius information, the plate spacing is shortened based on the radius adjustment parameter every preset time, and the temperature change rate of the cigarette per unit time is detected.

[0048] In the embodiment of the present application, the target temperature to which the cigarette needs to be heated is different depending on the tobacco material in the cigarette. Therefore, the controller will determine the target temperature to which the cigarette needs to be heated based on the tobacco material information, and collect and determine the current temperature of the cigarette. The controller will be pre-set with multiple temperature ranges, and different temperature ranges correspond to different radius adjustment parameters. Therefore, the controller will determine the radius adjustment parameter corresponding to the calculated temperature difference, and use this as the standard for each adjustment of the plate spacing to shorten the plate spacing, and then determine the temperature change rate.

[0049] In one possible implementation, the larger the temperature difference is, the larger the radius adjustment parameter is.

[0050] In the embodiment of the present application, when the temperature difference is larger, it means that the current temperature of the cigarette is further away from the temperature at which aerosol can be preferably precipitated, and for the sake of heating efficiency, it needs to be heated faster. In addition, since the general trend of the change of the electric field strength is to increase when the distance between the plates is reduced, the larger the temperature difference is, the larger the radius adjustment parameter corresponding to the temperature range to which it belongs will be, so that the change amplitude of the electric field strength each time is larger, so that it can be heated to the target temperature faster.

[0051] For example, when the radius adjustment parameter is 2mm, if the radius range is 0-20mm, then after a preset time (for example, 30s), the distance between the plates will change according to the trend of 20mm, 18mm, 16mm..., and each time the distance between the plates changes, the controller will calculate the temperature change rate of the cigarette per unit time, so as to subsequently compare the temperature change rates corresponding to each distance between the plates.

[0052] In one embodiment, the detecting the temperature change rate of the cigarette within a unit time includes:

[0053] The temperature change value of the cigarette within the preset time period is calculated, and the ratio of the temperature change value to the preset time period is calculated, and the ratio is the temperature change rate.

[0054] In an embodiment of the present application, the controller will calculate the temperature change value of the cigarette during the preset time period with a preset time period as a cycle, and divide the temperature change value by the preset time period. The ratio obtained is the temperature change rate per unit time.

[0055] S103, determining a target plate spacing when the temperature change rate is the highest, and adjusting the current plate spacing to the target plate spacing.

[0056] In an embodiment of the present application, the controller will determine the electrode spacing corresponding to the temperature change rate with the highest value among the temperature change rates detected in the aforementioned steps, use it as the target electrode spacing, and adjust the current electrode spacing to the target electrode spacing to ensure optimal heating efficiency of the inserted cigarette.

[0057] In one possible implementation, the cigarette parameter information further includes tobacco density information;

[0058] Determining the target plate spacing when the temperature change rate is the highest includes:

[0059] Calculating the minimum deformation area of ​​the cigarette based on the tobacco density information, and determining the first electrode plate spacing corresponding to the minimum deformation area;

[0060] Determine the second plate spacing when the temperature change rate is the highest;

[0061] When the second electrode plate spacing is not less than the first electrode plate spacing, the second electrode plate spacing is used as the target electrode plate spacing;

[0062] When the second electrode plate spacing is smaller than the first electrode plate spacing, the first electrode plate spacing is used as a target electrode plate spacing.

[0063] In the embodiment of the present application, in the process of the cigarette being squeezed by the plate, in addition to affecting the capacitor structure between the plates, the change in the cross-sectional area of ​​the cigarette will also cause the change in the density of tobacco in the cigarette. If the squeezing is too severe, the tobacco material in the cigarette is too dense, which will lead to poor air flow, and then make the user very strenuous when smoking, affecting the user experience. Therefore, the plate spacing is not the smaller the better. Therefore, the controller first needs to determine the minimum deformation area of ​​this type of cigarette according to the tobacco density information. The determination of the minimum deformation area can be determined by the manufacturer through a large amount of data experiments during the cigarette production design stage. After obtaining the minimum deformation area, the first plate spacing corresponding to the minimum deformation area can be determined. The first plate spacing is the minimum spacing that the cigarette can be squeezed. If the plate spacing is less than the first plate spacing, the gas flow in the cigarette will be poor and the user will have difficulty in smoking. Therefore, the controller will compare the first plate spacing with the second plate spacing. If the second plate spacing is not less than the first plate spacing, the second plate spacing will be directly used as the target plate spacing. If the second electrode plate spacing is smaller than the first electrode plate spacing, in order to ensure the user's smoking experience, the controller will choose to sacrifice a part of the heating efficiency and use the first electrode plate spacing as the target electrode plate spacing.

[0064] In one embodiment, the method further comprises:

[0065] An association relationship between the cigarette parameter information and the target plate spacing is constructed, and when the cigarette parameter information is detected again, the target plate spacing is called based on the association relationship.

[0066] In an embodiment of the present application, after determining the target pole plate spacing, the controller will also associate the cigarette parameter information with the target pole plate spacing and store the association relationship, so that the next time the inserted cigarette is detected to be a cigarette corresponding to the cigarette parameter information, it can be adjusted directly based on the target pole plate spacing to further improve the heating efficiency.

[0067] The following will be combined with the attached Figure 2 , the heating efficiency control device of the radio frequency heating smoking device provided in the embodiment of the present application is introduced in detail.
