Description

The present invention relates to the field of electronic atomization devices, in particular to a remaining electric power-based puff number calculation method for an aerosol generator, and an aerosol generator. BACKGROUND At present, a commonly used electronic atomization device, also known as an aerosol generation device, includes an atomizer and a battery body, wherein the atomizer is fixedly threaded to an upper surface of the battery body and includes a base. An airway is provided in the center of the base. An atomization core is provided in the airway. A holder is provided at an upper part of the airway. A housing is provided on an edge of the base. An inner wall of the housing and an outer wall of the airway enclose an E-liquid cabin. An E-liquid inlet hole is formed in a side wall of the airway, E-liquid flows to the atomization core through the E-liquid inlet hole, and the smoke generated from atomization of the E-liquid flows out of the holder. An air inlet hole is further formed in the base, and the air inlet hole is located below the airway and communicates with the airway, which facilitates outside air to be continuously replenished to the atomization core. The atomization core includes E-liquid guide cotton and a heating wire / heating net wound on the E-liquid guide cotton. The E-liquid in the E-liquid cabin flows to both ends of the E-liquid guide cotton through the E-liquid inlet hole, and then flows toward a middle position of the E-liquid guide cotton. The heating wire or heating net generates heat to continuously atomize the E-liquid adsorbed by the E-liquid guide cotton, and the smoke generated from atomization of the E-liquid flows out of the airway and enters the oral cavity of a human. When this electronic atomization device is in use, it is necessary to always pay attention to the electric power of the battery. If the electric power is insufficient, the atomization core cannot work. At present, a method of directly observing an electric power with the human eyes is adopted, and a display screen is provided on a body surface of the electronic atomization device. The display screen is connected to a circuit board, and the circuit board is connected to the battery. A voltage 1 value is displayed on the display screen. As the voltage value drops, the electric power of the battery on the surface becomes less and less. However, this rough display method for the voltage value is likely to cause misjudgment of a user. For example, when the display screen turns green, it means that the electric power is normal. The voltage of the battery fluctuates from 2.3V to 3.7V (this numerical value is only for illustration as an example), but there are two endpoint values, 2.3 V and 3.7 V. These two numerical values correspond to the different electric powers of the battery, one is an upper limit of normal electric power, and the other is a lower limit of normal electric power, which are reflected on the display screen with the same green light, indicating that the electric power is normal. Although the two values are both shown with the green light, but the usage time is very different, and the user is thus easy to misunderstand. In view of the above problems, at present, some research and development personnel have added a voltage value display on the display screen to directly display a voltage value of the remaining electric power. According to this voltage value, the user can be informed of the remaining electric power of the battery and then reminded of the electric power of the battery. However, the user can only judge the rest usage time of the battery according to his or her own puffing habits, which causes great distress to the user. In the case of preset normal puffing, the time spent by one puff of the user is sometimes long and consumes relatively large electric power, but is sometimes short and consumes relatively small electric power. As a result, how many puffs may be obtained with the remaining electric power makes the user confused, or even overwhelmed, resulting in inconvenience in actual use. SUMMARY Technical problem An object of the present invention is to overcome the defects in the prior art and to provide a remaining electric power-based puff number calculation method for an aerosol generator, and an aerosol generator, which has the characteristics of automatic prompt and dry burning prevention. Technical solutions The present invention provides a remaining electric power-based puff number calculation method for an aerosol generator. The method includes the following steps: Step a, providing a main body, wherein the main body is configured with a memory and a processor; the memory is connected to the processor and configured with preset information therein; the preset information includes an electric power CO of a battery, a rated power PO, a duration TO of a predetermined puff and the conversion efficiency A of the battery; and in this state, an ideal puff number of a cartridge is puffO, puff0=(C0*3600*A) / (P0*T0); Step b, detecting a current remaining electric power Cl of the battery when the cartridge is docked to the main body, and calculating a rest puff number puffl according to Cl, PO, TO and A by the processor, puffl =(Cl*3600*A) / (P0*T0); and Step c, starting to perform a puff number processing action by the processor when a power of the aerosol generator is changed from the rated power PO to an output power P2, that is, starting timing, counting a puffing number and a duration of one puff in this state, redetermining a duration T2 of the current puff number according to the longest duration of one puff in the counted puff number, detecting a current remaining electric power C2 of the battery again, and calculating the rest puff number puff2 in this state according to C2, P2, T2 and A by the processor, puff2=(C2*3600*A) / (P2*T2). In step b, the cartridge is docked to the main body, the processor is in a standby state. Within a first preset duration, puffl is calculated directly according to the remaining electric power Cl, the duration TO of the predetermined puffs, the conversion efficiency A of the battery and the rated power PO if the processor does not receive power changed information. If the processor receives the power changed information, the processor starts to count a puffing duration of each puff within a second preset duration according to the changed output power P2, and counts a puff number within the second preset duration; and if the output power P2 is not changed within the second preset duration, the processor detects C2, and redetermines the puffing duration T2 according to the longest duration of one puff in the puff number counted within the second preset duration, and then calculates puff2 according to C2, P2, T2 and A. If the output power P2 is changed within the second preset duration, the processor starts to re-count the puffing duration of each puff again within an nth preset duration according to the changed output power Pn, and counts the puff number within the nth preset duration; and if the output power Pn within the nth preset duration is not changed, the processor detects the current remaining electric power Cn of the battery, redetermines the puffing duration Tn according to the longest duration of one puff in the puff number counted within the nth preset duration, and then calculates puffn according to Cn, Pn, Tn and A. Optionally, the method further includes: obtaining a rest duration Tpost for which the rest puff number puff2 can spend according to an experience reference puff number puff3 within an experience reference duration Tpre, the experience reference duration Tpre and the rest puff number puff2 when the power of the aerosol generator is changed from the rated power PO to the output power P2 by the processor, wherein the experience reference duration Tpre refers to an experience puffing duration extracted from an existing duration of completed puffs, and the experience reference puff number puff3 refers to an experience puff number extracted from the existing duration of the completed puffs. Optionally, a calculation formula of the rest duration Tpost is as follows: TpOst= puff2*Tpre / pufif3. Optionally, the method further includes: obtaining a rest duration Trest for which the remaining electric power C2 can be used according to the electric power Cpre consumed within the experience reference duration Tpre, the current remaining electric power C2 of the battery and the experience reference duration Tpre by the processor, a calculation formula of Trest is as follows: Trest=C2*Tpre / CPre- The present invention further provides an aerosol generator.

Apparently, the accompanying drawings in the following description show merely some embodiments of the present invention, and a person of ordinary skill in the art may still derive other drawings from these accompanying drawings without creative efforts. FIG. lisa flowchart provided by an embodiment of the present invention; and FIG. 2 is a schematic diagram of an electronic atomization device provided by an embodiment of the present invention. DETAILED DESCRIPTION The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely some embodiments of the present invention rather than all embodiments. Based on the embodiments of the present invention, all other embodiments derived by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. As shown in FIGs. 1 to 2, the present invention mainly relates to an electronic atomization device, which may generally be understood as an aerosol generator, in which a change process of liquid to smoke is achieved by heating E-liquid, and then the smoke is sucked into the oral cavity of a human. An embodiment of the present invention provides a remaining electric power-based puff number calculation method for an aerosol generator. The method includes the following steps: Step a, providing a main body, wherein the main body is configured with a memory and a processor; the memory is connected to the processor; the main body includes a housing in which at least one battery and at least one circuit board are provided; a display screen is disposed on a surface of the housing, and is connected to the circuit board; the processor and the memory are disposed on the circuit board; the memory is configured with preset information therein, and the preset information includes an electric power CO (with the electric power unit being Wh, wherein Wh=(mAh*3.7) / 1000) of the battery, a rated power P0, a duration TO (three seconds per puff in industrial design) of a predetermined puff and the conversion efficiency A of the battery; and in this state, an ideal puff number of a cartridge is puffO, puff0=(C0*3600*A) / (P0*T0). For example, the preset (or set) electric power CO of the battery is that C0=1000mAh=3.7wh, the rated power P0 is 15W, the conversion efficiency A of the battery is 90%, and the predetermined PuffO, also known as the rest puff number, may be calculated to be 266.4 by substituting numerical values. Step b, detecting a current remaining electric power Cl of the battery when a cartridge is docked to the main body, and calculating a rest puff number puffl according to Cl, P0, TO and A by the processor, an atomization core and E-liquid are disposed in the cartridge; and the atomization core is docked to a voltage output port of the main body by an elastic pin; for example, docking of the cartridge with main body is realized by using a magnetic attraction method or a snapping / buckling method, puffl=(C 1*3600* A) / (P0*T0). For example, the remaining electric power Cl of the battery is that Cl=900mAh=3.4wh, and Puffl, also known as the rest puff number, may be calculated to be 244.8 by substituting numerical values. Step c, starting to perform a puff number processing action by the processor when a power of the aerosol generator is changed from the rated power PO to an output power P2, that is, starting timing, counting a puff number and a duration of one puff in this state, redetermining a duration T2 of the current puff number according to the longest duration of one puff in the counted puff number, detecting a current remaining electric power C2 of the battery, and calculating the rest puff number puff2 in this state according to C2, P2, T2 and A by the processor, puff2=(C2*3600*A) / (P2*T2). For example, the remaining electric power C2 of the battery is that C2=800mAh=2.9wh, P2 is 12W, the conversion efficiency A of the battery is 90%, and pufF2, also known as the rest puff number, may be calculated by substituting numerical values. The rest puff number is calculated according to basic information (for example, power and duration, etc) about puff number in this state, thus the user obtains a more intuitive numerical value of the rest puff number of the electronic atomization device. In the step b, the cartridge is docked to the main body, and the processor is in a standby state. Within a first preset duration, if the processor does not receive power changed information, puffl is calculated directly according to the remaining electric power Cl, the duration TO of the predetermined puffs, the conversion efficiency A of the battery and the rated power PO. It should be noted here that the first preset duration may be a user-defined duration or an initial set duration, which will not be specifically limited herein. Therefore, Cl is detected again in the case that PO is not changed within the first preset duration, thus the rest puff number puffl can be calculated more accurately. In the step c, if the processor receives the power changed information, the processor starts to count a puffing duration of each puff within a second preset duration according to the changed output power P2, and counts a puff number within the second preset duration; and if the output power P2 is not changed within the second preset duration, the processor detects C2, and redetermines the puffing duration T2 according to the longest duration of one puff in the puff number counted within the second preset duration, and then calculates the rest puff number puff2 according to C2, P2, T2 and A. It should be noted here that the second preset duration may be a user-defined duration or an initial set duration, which will not be specifically limited herein. In addition, the second preset duration may be the same as the first preset duration, or may be different from the first preset duration, which will not be specifically limited herein. Therefore, C2 is detected again in the case that P2 is not changed within the second preset duration, thus the rest puff number puff2 can be calculated more accurately. If the output power P2 is changed within the second preset duration, the processor starts to re-count the puffing duration of each puff again within an nth preset duration according to the changed output power Pn, and counts the puff number within the nth preset duration; and if the output power Pn within the nth preset duration is not changed, the processor detects the current remaining electric power Cn of the battery, and redetermines the puffing duration Tn according to the longest duration of one puff in the puff number counted within the nth preset duration, and then calculates the rest puff number puffin according to Cn, Pn, Tn and A, n is a natural number. It should be noted here that the nth preset duration may be a user-defined duration or an initial set duration, which will not be specifically limited herein. In addition, the nth preset duration may be the same as the first preset duration, or may be different from the first preset duration, which will not be specifically limited herein. Therefore, Cn is detected again in the case that Pn is not changed within a certain time, thus the rest puff number puffn can be calculated more accurately. The present invention provides a remaining electric power-based puff number calculation method for an aerosol generator, by means of extracting and screening the longest puffing duration within a certain time, determining the output power, and detecting the remaining electric power of the battery, the minimum puff number is finally calculated. The user obtains the minimum rest puff number according to a puffing situation of the user (according to different puffing durations and different output powers). In addition, the user may clearly observe the output power, the minimum rest puff number and other information through the display screen disposed on the surface of the main body after completing the puffing action and give a clear prediction and precise estimation for future uncertain information, which facilitates the user to determine a next action, and know in advance the duration for which the aerosol generator can be used based on the minimum rest puff number of the aerosol generator. In the remaining electric power-based puff number calculation method for an aerosol generator in the embodiments of the present invention, there may also be the following two different technical solutions for the processor to calculate the rest duration for which the aerosol generator can be used. In the first technical solution, when the power of the aerosol generator is changed from the rated power PO to the output power P2, the processor detects the current remaining electric power C2 of the battery again. After the rest puff number puff2 in this state is calculated, this method may further include: Obtaining a rest duration Tpost that the rest puff number puff2 can spend according to an experience reference puff number puff3 within the experience reference duration Tpre, the experience reference duration Tpre and the rest puff number puff2 when the power of the aerosol 7 generator is changed from the rated power PO to the output power P2 by the processor, wherein the experience reference duration Tpre refers to an experience puffing duration extracted from existing duration of completed puffs, and the experience reference puff number puff3 refers to an experience puff number extracted from the existing duration of completed puffs. Further, a calculation formula of the rest duration Tpost is as follows: TpOst= puff2*Tpre / puff3. In this embodiment, by calculating the rest duration Tpost by the processor, the user can more accurately learn of how long the aerosol generator can still be used, which improves the practicality of a product. It is understood here that after completing the puffing action, the user may observe the rest duration Tpost through the display screen. In the second technical solution, after the processor detects the current remaining electric power C2 of the battery again and calculates the rest puff number puff2 in this state, this method may further include: obtaining a rest duration Trest for which the remaining electric power C2 can be used according to the electric power Cpre consumed within the experience reference duration Tpre, the current remaining electric power C2 of the battery and the experience reference duration Tpre by the processor, wherein the calculation formula of the rest duration Trest is as follows: Trest=C2 * Tpre / CPre • In this embodiment, by calculating the rest duration Trest by the processor, the user can more accurately learn of how long the aerosol generator can still be used, which improves the practicality of the product. It is understood here that after completing the puffing action, the user may observe the rest duration Trest through the display screen. The present invention further provides an aerosol generator. The aerosol generator includes a main body and a cartridge, wherein the main body is configured with a memory and a processor; the memory is connected to the processor; the cartridge is docked to the main body; and the processor is configured to perform all the embodiments of the remaining electric power-based puff number calculation method for an aerosol generator.
