The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0029] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Figure 1 Schematic diagram of the structure of the aerosol generating device provided by the embodiment of the present application, as Figure 1 shown, the aerosol generating device 100 includes a battery cell 10, a main board 20 and an atomizer 30. A controller of the aerosol generating device 100 is provided on the main board 20. The battery cell 10 and the atomizer 30 are respectively electrically connected to the controller, so that the controller can control the battery cell 10 to supply electric energy to the atomizer 30. A longitudinally extending chamber 40 is further provided in the aerosol generating device 100. The chamber 40 is used to accommodate the solid aerosol generating substrate 200 used in conjunction with the aerosol generating device 100. The atomizer 30 is used to atomize the aerosol generating substrate 200 in the chamber 40 to generate aerosol, so that the user can inhale the aerosol by sucking on the aerosol generating substrate 200.

[0031] In some embodiments, the atomizer 30 may be a mesh resistive heating element coated on the outer wall of the chamber 40. The mesh resistive heating element 30 is electrically connected to the main board 20. After the mesh resistive heating element 30 is powered on, it generates heat and transfers the heat to the aerosol-forming substrate 200 in the chamber 40. Some of the active substances filled inside the aerosol-forming substrate 200 are volatilized by heat to generate aerosol.

[0032] Figure 2 The following is a schematic structural diagram of an aerosol generating device provided in another embodiment of the present application. As Figure 2 shown, the aerosol generating device 100 may also use electromagnetic induction heating to atomize the aerosol-forming substrate 200 to generate aerosol. The atomizer 30 extends at least partially into the chamber 40, and the end thereof extending into the chamber 40 is formed into a pin shape or a sheet shape, so that the atomizer 30 can be smoothly inserted into the aerosol-forming substrate 200 for heating and atomization. A coil 50 is wound around the outer wall of the chamber 40. The controller controls the battery cell 10 to pass an alternating current into the coil 50. The coil 50 generates a changing magnetic field under the action of the alternating current. The changing magnetic field penetrates the atomizer 30 and then induces eddy currents in the atomizer 30. The atomizer 30 generates heat under the action of the eddy current effect and the hysteresis effect, and then can heat the aerosol-forming substrate 200.

[0033] The aerosol-forming substrate 200 is preferably a tobacco-containing material that releases volatile compounds from the substrate when heated; or it may also be a non-tobacco material that is suitable for electrically heated smoking after heating. The aerosol-forming substrate 200 is preferably a solid substrate, and may include one or more of powder, granule, fragment, strip, strip or sheet of vanilla leaf, tobacco leaf, homogenized tobacco, expanded tobacco, etc.; alternatively, the solid substrate may contain additional tobacco or non-tobacco volatile flavor compounds to be released when the substrate is heated.

[0034] Suitable materials for the atomizer 30 can be any one of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, iron, copper, nickel-containing compounds, titanium, and metal material composites. In some embodiments, to better induce eddy currents to improve the heating efficiency, the material of the atomizer 30 is preferably a ferromagnetic material or composed of a ferromagnetic material, and ferromagnetic materials such as ferrite iron, ferromagnetic alloys (such as ferromagnetic steel or stainless steel), ferromagnetic particles, and ferrites.

[0035] In some other embodiments, the aerosol generating device 100 may also heat and atomize the liquid aerosol-forming substrate 200 to generate aerosol.

[0036] Figure 3 The following is a schematic structural diagram of an aerosol generating device provided in another embodiment of the present application. AsFigure 3 As shown, the aerosol generating device 100 includes a housing 90a. The housing 90a is provided with an air inlet hole 92a for external air to enter the aerosol generating device 100, and a mouthpiece 91a for the user to inhale the aerosol. A liquid storage cavity 10a is provided inside the housing 90a. A vaporizable liquid aerosol generating matrix is stored in the liquid storage cavity 10a. A gas guide tube 20a extends longitudinally in the liquid storage cavity 10a. One end of the gas guide tube 20 is communicated with the mouthpiece 91a. To seal the liquid storage cavity 10a, a sealing member 50a is further provided in the housing 90a. The sealing member 50a is in interference fit with the inner wall of the housing 90a to seal the liquid storage cavity 10a.

[0037] A nebulizer is provided in the gas guide tube 20. The nebulizer includes a liquid guiding element 30a and a heating element 40a combined with the liquid guiding element 30a. The liquid guiding element 30a partially extends into the liquid storage cavity 10a. The liquid guiding element 30a is made of a hygroscopic material, such as non-woven fabric, cotton fiber, glass fiber or porous material, etc. The heating element 40a can be combined with the liquid guiding element 30a by means of printing, deposition, sintering or physical assembly, or wound around the liquid guiding element 30a. Thus, the liquid matrix in the liquid storage cavity 10a can be absorbed by the liquid guiding element 30a. The liquid guiding element 30a further transfers the liquid matrix to the heating element 40a through the tiny voids or microporous structures inside it. The heating element 40a heats and atomizes the liquid matrix to generate an aerosol, and releases the aerosol into the gas guide tube 20a. A ventilation hole 51a is provided on the sealing member 50a. The ventilation port 51a is communicated with the gas guide tube 20a. When the user sucks at the mouthpiece 91a, after the external air enters the aerosol generating device 100 through the air inlet hole 92a, it then flows into the ventilation hole 51a through the internal air flow channel, enters the gas guide tube 20a through the ventilation hole 51a, and finally carries the aerosol in the gas guide tube 20a to the mouthpiece 91a for the user to inhale.

[0038] The aerosol generating device 100 further includes an airflow sensing element 80a and a main board 70a. A controller of the aerosol generating device 100 is provided on the main board 70a. When the user sucks at the mouthpiece 91a, a negative pressure is generated inside the aerosol generating device 100. The airflow sensing element 70a senses the negative pressure and generates an induction signal. The induction signal is sent to the controller, and the controller can control the nebulizer to start working according to the induction signal.

[0039] It should be noted that the method for the aerosol generating device 100 to atomize the aerosol generating substrate 200 to generate aerosol is not limited to the above embodiments. Those skilled in the art can also use other well-known methods to atomize the aerosol generating substrate 200 to generate aerosol. For example, infrared heating atomization, air heating atomization, etc. can also be used. Moreover, in some embodiments, the aerosol generating device 100 can also use ultrasonic atomization to atomize the liquid aerosol generating substrate 200 to generate aerosol.

[0040] Figure 4 FIG. is a flowchart of a data storage method based on an aerosol generating device provided by an embodiment of the present application. This data storage method is based on Figures 1-3 the aerosol generating device 100 shown. As Figure 4 shown, the data storage method based on the aerosol generating device includes the following steps:

[0041] S410. Receive the first data to be written.

[0042] Among them, the first data is the target data to be written for the first time after the system power supply of the battery cell in the aerosol generating device fails and resumes power supply.

[0043] It should be noted that the system power supply fails and resumes power supply, which is also equivalent to the first power supply to the FLASH memory.

[0044] The first data can be the number of puffs, the duration of each puff, or the total puff duration of the aerosol generating device 100. By recording these parameters, the user can understand their own puffing habits. At the same time, the aerosol generating device 100 can also judge the remaining number of puffs or puff duration based on these parameters to feedback the current usage status of the aerosol generating device 100 to the user.

[0045] S420. Search for available storage space in a read / write operation unit of the FLASH memory. Among them, a read / write operation unit contains multiple consecutive data storage addresses, and the available storage space is n consecutive data storage addresses in the erased state.

[0046] As an example rather than a limitation, the value of n can be 6, or it can also be 7. The specific n can be set according to the actual application scenario and is not limited here.

[0047] Exemplarily, the address of a read / write operation unit ranges from 0x08007800 to 0x08007BFF, and its space size is 1024 bytes, that is, 1K. Therefore, a data storage address in the erased state can be represented by 0xFF.

[0048] S430. If there is available storage space, write the first data within the available storage space.

[0049] It can be understood that within a read / write operation unit, the available storage space is less than or equal to the read / write operation unit.

[0050] S440. If there is no available storage space, erase the corresponding read / write operation unit, and when the erasure is completed, write the first data.

[0051] Among them, the non - existence of available storage space can be understood as: the corresponding read / write operation unit is full, that is, there is no available storage space in a read / write operation unit, which means the read / write operation unit is full of data. Thus, erase the read / write operation unit full of data, and then write new data.

[0052] At least one advantageous aspect of the data storage method based on the aerosol - generating device provided by the embodiments of the present application is that when writing data to the aerosol - generating device, by searching whether there is available storage space in the read / write operation unit of the FLASH memory in the aerosol - generating device, if there is, write the data; if not, first erase the read / write operation unit and then write the data. Thus, it avoids frequently erasing the FLASH memory before writing new data each time, and can cycle - write data in the read / write operation unit of the FLASH memory until it is full and then erase it, thereby reducing the number of erasures of the FLASH memory, increasing the service life of the FLASH memory, and increasing the service life of the aerosol - generating device.

[0053] Figure 5 It is a flowchart of the data storage method based on the aerosol - generating device provided by another embodiment of the present application. As Figure 5 shown, the data storage method based on the aerosol - generating device includes the following steps:

[0054] S510. Receive the first data to be written.

[0055] The execution steps of step S510 are the same as those of step S410, and will not be elaborated here.

[0056] S520. Search for available storage space among the read / write operation units of the FLASH memory, where a read / write operation unit contains multiple consecutive data storage addresses, and the available storage space is n consecutive data storage addresses in the erased state.

[0057] It should be noted that a read / write operation unit is the smallest erasure or write unit, and the number of read / write operation units receiving the first data is one or more. Therefore, the embodiments of the present application can be applied not only to one read / write operation unit, but also to more than one consecutive read / write operation units.

[0058] S530. If there is available storage space, among the consecutive n data storage addresses in the erased state, determine that the first data storage address is the starting address of the first data.

[0059] Base Address: Also known as the starting address, the address of the first byte in the storage area is used as the starting address of the storage area, also known as the base address. That is, take the first data storage address among the consecutive n data storage addresses in the erased state as the starting address of the first data.

[0060] Exemplarily, as Figure 6 shown, Figure 6 is a schematic diagram of an embodiment of the starting address of the first data provided by the embodiment of the present application. Assume that n is 6, and a data storage address in the erased state is represented by 0xFF. If there is available storage space, determine that the first 0xFF among the consecutive 6 0xFFs is the starting address of the first data.

[0061] S540. Using the starting address of the first data as the starting address, write the first data.

[0062] Exemplarily, assume that the first data is: 55555555 00000100. Based on Figure 6 , using the starting address of the first data as the starting address, write the first data to obtain a schematic diagram of the embodiment with the first data written as shown in Figure 7 .

[0063] S550. If there is no available storage space, read the data written last time in the corresponding read / write operation unit.

[0064] Among them, the situation of no available storage space can be understood as: the corresponding read / write operation unit is full. That is, when there is no available storage space in a read / write operation unit, it means that the read / write operation unit is full of data.

[0065] S560. When the reading is completed, erase the corresponding read / write operation unit.

[0066] S570. When the erasure is completed, determine the starting address in the erased read / write operation unit as the starting address of the first data.

[0067] It can be understood that each data storage address in the erased read / write operation unit is in the erased state. Exemplarily, as Figure 8As shown Figure 8 FIG. is a schematic diagram of an embodiment of a read / write operation unit after erasure provided by an embodiment of the present application.

[0068] S580: Starting from the starting address of the first data, write the first data.

[0069] Exemplarily, as Figure 9 shown Figure 9 FIG. is a schematic diagram of an embodiment in which the starting address in the read / write operation unit after erasure provided by an embodiment of the present application is determined as the starting address of the first data.

[0070] By erasing the read / write operation unit only when it is full in a FLASH memory, frequent erasure of the FLASH memory before each write of new data can be avoided, thereby increasing the service life of the FLASH memory.

[0071] In some embodiments, the data storage method based on the aerosol generating device further includes: (1) receiving the second data to be written; (2) determining the starting address of the second data according to the data length of the first data and the starting address of the first data; (3) starting from the starting address of the second data, writing the second data.

[0072] Wherein, the second data is: the next target data to be written after writing the first data and when the system power supply continues to be normally powered.

[0073] Exemplarily, based on Figure 7 , according to the data length of the first data and the starting address of the first data, determine the starting address of the second data. The starting address of the second data is as Figure 10 shown Figure 10 FIG. is a schematic diagram of an embodiment of the starting address of the second data provided by an embodiment of the present application.

[0074] When the system power supply continues to be normally powered, after writing the first data, the first data is not erased, and the second data is continuously written on the basis of the first data, thereby avoiding frequent erasure of the FLASH memory before each write of new data, and further increasing the service life of the FLASH memory.

[0075] At least one advantageous aspect of the data storage method based on an aerosol generating device provided by an embodiment of the present application is that when writing data to the aerosol generating device, by searching whether there is available storage space in the read / write operation unit of the FLASH memory in the aerosol generating device, if there is, the data is written, if not, the read / write operation unit is erased first and then the data is written, thereby avoiding frequent erasure of the FLASH memory before each new data is written, and being able to cyclically write data to the read / write operation unit in the FLASH memory until it is full and then erased, thereby reducing the number of erasures of the FLASH memory, increasing the service life of the FLASH memory, and increasing the service life of the aerosol generating device.

[0076] An embodiment of the present application further provides a computer-readable storage medium. The computer-readable storage medium can be a non-volatile computer-readable storage medium. The computer-readable storage medium stores a computer program.

[0077] Wherein, when the computer program is executed by a processor, it implements one or more steps in the data storage method based on an aerosol generating device disclosed in the embodiment of the present application. The complete computer program product is embodied on one or more computer-readable storage media containing the computer program disclosed in the embodiment of the present application (including but not limited to, disk memory, CD-ROM, optical memory, etc.).

[0078] In summary, an embodiment of the present application proposes a data storage method based on an aerosol generating device. The data storage method based on an aerosol generating device, when writing data to the aerosol generating device, by searching whether there is available storage space in the read / write operation unit of the FLASH memory in the aerosol generating device, if there is, the data is written, if not, the read / write operation unit is erased first and then the data is written, thereby avoiding frequent erasure of the FLASH memory before each new data is written, and being able to cyclically write data to the read / write operation unit in the FLASH memory until it is full and then erased, thereby reducing the number of erasures of the FLASH memory, increasing the service life of the FLASH memory, and increasing the service life of the aerosol generating device. Moreover, when the system power supply continues to supply power normally, after writing the first data, the first data is not erased, and the second data is continuously written on the basis of the first data, thereby avoiding frequent erasure of the FLASH memory before each new data is written, and further increasing the service life of the FLASH memory, and increasing the service life of the aerosol generating device.
