Description

(Cross-reference of related applications) This application claims priority to the Chinese patent application filed with the China National Intellectual Property Administration on May 5, 2023, application number 202310499555.4, with the title of the invention "Method for controlling an aerosol generator and the aerosol generator itself," and all contents of that application are incorporated into this application by reference. This application relates to the technical field of low-temperature tobacco, and more specifically, to a control method for an aerosol generator and to an aerosol generator itself. Conventional tobacco products (e.g., cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Currently, there are alternatives to these conventional tobacco products that release compounds through heating rather than combustion. An example of such a product is an aerosol generator containing a heating element. The heating element heats a cigarette-shaped aerosol generator inserted into the device, causing some of the active substances in the aerosol generator to volatilize due to the heat, thereby generating an aerosol. Existing aerosol generators typically use a temperature sensing element to determine whether a warm or cold start is required. Furthermore, they control the heating of the aerosol generator using a heating element based on the start temperature, ensuring consistent taste for the user during smoking in both warm and cold starts. However, adding a temperature sensing element increases the manufacturing cost of the aerosol generator accordingly. The embodiments of this application provide a control method for an aerosol generator and an aerosol generator, and offer a method for identifying hot-start or cold-start aerosols that differs from the taste difference between aerosols generated by hot-start and cold-start aerosol generators, using a method different from that which relies on a temperature sensing element. In one embodiment of this application, a method for controlling an aerosol generator including a heating element for generating an aerosol by heating an aerosol generating product is provided, comprising the steps of: starting the aerosol generator; determining the shutdown time of the aerosol generator, wherein the shutdown time is the time interval from the previous shutdown time of the aerosol generator to the current startup time; and determining the preheating energy of the aerosol generator based on the shutdown time, controlling the heating element to output the preheating energy, and causing the aerosol generator to reach a preset target temperature. In some embodiments, the step of determining the preheating energy of the aerosol generator based on the shutdown time and controlling the heating element to output the preheating energy includes the steps of determining the preheating time of the aerosol generator based on the shutdown time, and controlling the heating element to output the preheating energy at a predetermined power within the preheating time, wherein the preheating time is the time required for the heating element to heat and raise the current temperature of the aerosol generator from the current startup temperature to the target temperature. In some embodiments, the step of controlling the heating element to output preheating energy at a predetermined power within the preheating time, based on the preheating time, includes the steps of determining the difference between the set preheating time and the preheating time and obtaining a delay time, wherein the set preheating time is the time for preheating at the predetermined power in the process of heating the aerosol generating product from ambient temperature to the target temperature; controlling the heating element to start heating when the power-on time of the aerosol generating device reaches the delay time; and controlling the heating element to stop heating when the heating time of the heating element reaches the preheating time. In some embodiments, the step of controlling the heating element to output preheating energy at a predetermined power within the preheating time, based on the preheating time, includes the steps of controlling the heating element to start heating simultaneously with the start time of the aerosol generator, and stopping heating by controlling the heating element when the heating time of the heating element reaches the preheating time, wherein the preheating time is less than or equal to a set preheating time, and the set preheating time is the time for preheating at the predetermined power in the process of heating the aerosol generating product from ambient temperature to the target temperature. In some embodiments, the step of determining the preheating time of the aerosol generator based on the shutdown time includes a step of determining a target preheating time corresponding to the shutdown time as the preheating time, based on a mapping relationship of pr
