Inventor: SONG XINHUA
IPC: A24F47/00
Filed: 2020-07-06
Abstract: Provided is a heating control method for a heating non-combusting smoking implement, comprising the following steps: detecting the motion parameters of a smoking implement (S101); according to the motion parameters, determining whether a current action is a target action (S102); if the current action is a target action, then triggering a preheating instruction and, on the basis of a preheating instruction, controlling the heating of the heating element (204) of the smoking implement (S103). By means of detection and analysis of the motion parameters of the smoking implement, it is determined whether the current action of the user is a target action; without turning on the heating switch on the smoking implement, it is possible to automatically trigger the preheating instruction and heat the heating element (204) on the basis of the pre-heating instruction. Not only is the invention very convenient and improves the user experience, but also, if the current action of the user is not the target action, the preheating instruction is not triggered, thus reducing energy waste and increasing the number of cigarettes that the user can smoke after each charge.
