Description

Technical Field

[0001] The invention belongs to the field of aerosol generating device control, and in particular relates to an aerosol generating device safety control method and an aerosol generating device. Background Art

[0002] At present, many safety control measures have been added to ensure the safety of aerosol generating devices during use. For example: detection of battery temperature, detection of atomizer short circuit, detection of main control board temperature, etc. In order to ensure that electronic components maintain their stable performance output during normal use, the current common practice is that when the whole machine is outputting power, the main control MCU detects that the temperature of the temperature sensor on the main control board exceeds the alarm value, and directly shuts off the output and gives a corresponding prompt to alarm. When the main control MCU detects that the temperature is less than the alarm value, it allows the cigarette to be re-lit and output. If the user does not pay attention to the temperature of the main control board, the control method of suddenly shutting off the power when the temperature exceeds the alarm value will directly affect the user's smoking experience. Summary of the invention

[0011] According to the temperature alarm initial value and the temperature alarm interval value, all temperature step values ​​that meet the temperature alarm step quantity are calculated; and the temperature alarm initial value and all the temperature step values ​​are used as temperature alarm values.

[0012] Furthermore, the temperature alarm interval value is at least one of a fixed value, a random value, and a value following a preset rule.

[0013] Further, get the current temperature value, including:

[0014] After the aerosol generating device is turned on, the current temperature value of the main control board is detected by the temperature sensor.

[0015] Further, according to the temperature alarm value, according to the preset rules, the temperature alarm range is obtained, including:

[0016] Sort all temperature alarm values ​​by size;

[0017] The area between two adjacent temperature alarm values ​​and the endpoint of the small temperature alarm value is taken as a temperature alarm range; the area with a value less than the minimum temperature alarm value is taken as a temperature alarm range; the area with a value greater than the maximum temperature alarm value is taken as a temperature alarm range.

[0018] Furthermore, there are multiple temperature alarm ranges; the operation corresponding to the temperature alarm range is to adjust the output power of the current aerosol generating device to the product of the current output power and a preset coefficient; different temperature alarm ranges correspond to different preset coefficients.

[0019] Further, the temperature alarm value includes a first temperature alarm value, a second temperature alarm value, a third temperature alarm value and a fourth temperature alarm value; the temperature alarm range includes a first alarm range, a second alarm range, a third alarm range, a fourth alarm range and a fifth alarm range;

[0020] If the current temperature value is within the temperature alarm range, the operation corresponding to the temperature alarm range is performed, including:

[0021] If the current temperature value is within the first alarm range, the output power is controlled to be adjusted to a first percentage of the current output power;

[0022] If the current temperature value is within the second alarm range, the output power is controlled to be adjusted to a second percentage of the current output power;

[0023] If the current temperature value is within the third alarm range, the output power is controlled to be adjusted to a third percentage of the current output power;

[0024] If the current temperature value is within the fourth alarm range, the output power is controlled to be adjusted to a fourth percentage of the current output power;

[0025] If the current temperature value is in the fifth alarm range, the output power is controlled to be adjusted to the fifth percentage of the current output power.

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented:

[0038] First embodiment:

[0039] The first embodiment of the present invention provides a safety control method for an aerosol generating device, comprising: obtaining a plurality of preset temperature alarm values; obtaining a current temperature value; obtaining a temperature alarm range according to the temperature alarm value and preset rules; comparing the current temperature value with the temperature alarm range, and if the current temperature value is within the temperature alarm range, executing an operation corresponding to the temperature alarm range to adjust the output power of the aerosol generating device.

[0040] Multiple temperature alarm values ​​are set to limit multiple temperature alarm ranges, and each temperature alarm range corresponds to a different output power change of the aerosol generating device; compared with only a single temperature alarm range, the aerosol generating device of this scheme is more flexible and can set the temperature alarm value according to its own selection, thereby solving the problem of directly shutting down the output of the aerosol generating device when the temperature alarm occurs and affecting the user experience; each temperature alarm range corresponds to a different output power change of the aerosol generating device, which can avoid the problem of poor taste caused by a sudden drop in the output power of the aerosol generating device.

[0041] The following is a detailed description of the implementation details of the aerosol generating device safety control method of this embodiment. The following content is only for the convenience of understanding the implementation details provided, and is not necessary for the implementation of this solution. The specific process of this embodiment is as follows: Figure 1 As shown, this embodiment is applied to an aerosol generating device.

[0042] Step 101, obtaining a plurality of preset temperature alarm values.

[0043] Specifically, there are several ways to obtain the temperature alarm value: First, the user directly transmits information through a keyboard, a data cable, a USB plug-in, etc. Second, the aerosol generating device is connected to the user client through wireless communication. After receiving the user personal information and user instructions sent by the user client, the aerosol generating device compares the user personal information with the user database stored in itself, thereby performing identity authentication. After the identity authentication is passed, the received user instruction is processed by analog / digital processing to obtain the corresponding temperature alarm value; the purpose of the user client remotely inputting the temperature alarm value is achieved. Third, the aerosol generating device stores a database of temperature alarm values, and the user selects the corresponding temperature alarm value from the database as the temperature alarm value of this step 101, or the aerosol generating device automatically selects the corresponding temperature alarm value as the temperature alarm value of this step 101 according to the type and taste of the aerosol generating matrix. Fourth, the aerosol generating device is connected to the external server through the Internet, and the temperature alarm value is directly obtained from the network where the server is located. The acquisition method can be to read data from a web page, or to directly extract keywords from a web page, etc.

[0044] In some examples, obtaining a preset temperature alarm value includes: S1-1, obtaining a temperature alarm initial value, a temperature alarm step value, and a temperature alarm interval value input by a user; S1-2, calculating all temperature step values ​​that meet the temperature alarm step value based on the temperature alarm initial value and the temperature alarm interval value; S1-3, using the temperature alarm initial value and all the temperature step values ​​as temperature alarm values.

[0045] Among them, the temperature alarm initial value, temperature alarm step value and temperature alarm interval value are input by the user, and the input method can be input through a data line or a wireless network. The temperature alarm initial value is usually set to the initial temperature alarm value, the temperature alarm step value usually represents the number of temperature alarm values ​​finally formed, and the temperature alarm interval value represents the difference between the temperature alarm values.

[0046] The specific process of step S1-2 is: take the temperature alarm initial value as the minimum value, take the temperature alarm interval as the difference, calculate all the values ​​within the temperature alarm step range, and use them as the temperature step value. For example: the temperature alarm initial value is A, the temperature alarm step is k, and the temperature alarm interval is j, then the temperature step value Bi is: Bi = A + j * (i-1), i is a positive integer [1, k].

[0047] When setting the temperature alarm interval value, a fixed value can be used. For example, the temperature alarm initial value is 60°C, the temperature alarm step value is 4, and the temperature alarm interval value is 5°C, then the temperature step values ​​are 65°C, 70°C, and 75°C.

[0048] The temperature alarm interval value can also be set to a random number. For example, the temperature alarm initial value is 60°C, the temperature alarm step value is 4, and the temperature alarm interval value is a random number rand(x). Then the temperature step value is: 60°C, 60+rand(x1)°C, 60+rand(x1)+rand(x2)°C, 60+rand(x1)+rand(x2)+rand(x3)°C. This means that when the temperature alarm interval value is a random value, there is no regularity in generating the temperature alarm value.

[0049] The temperature alarm interval value can also be set to a value that follows a preset rule, which is usually set as the formula y(x). For example, if the temperature alarm initial value is 60, the temperature alarm step value is 4, and the temperature alarm interval value is y(x), then the temperature step value is: 60℃, 60+y(x0)℃, 60+y(x0)+y(x1)℃, 60+y(x0)+y(x1)+y(x2)℃. Among them, x0, x1, and x2 are all series that meet the preset requirements, such as x0, x1, and x2 are arithmetic series.

[0050] Step 102, obtaining the current temperature value.

[0051] Specifically, after the aerosol generating device is turned on, the current temperature value of the main control board is detected by the temperature sensor. Specifically, after the aerosol generating device is turned on, the current temperature value of the main control board is measured once in each cycle according to a preset frequency. The preset frequency is pre-set by the staff, usually 160ms. The aerosol generating device usually includes a main control board, and a temperature sensor is installed on the main control board to detect the current temperature value of the main control board.

[0052] After the aerosol generating device is started, the atomizing device is started after receiving the cigarette lighting signal; the timing is t from the moment the cigarette lighting signal is received. When t>10s, it can be determined that the continuous generation time of the cigarette lighting signal reaches the maximum value (10s), and the atomizing device is controlled to be turned off, and the maximum cigarette lighting time is 10s. After 10 seconds, even if the button is still pressed, the program will automatically shut down the output.

[0053] Step 103, obtaining a temperature alarm range according to the temperature alarm value and a preset rule.

[0054] Specifically, the implementation of step 103 includes: S3-1, sorting all temperature alarm values ​​by size; S3-2, taking the area between two adjacent temperature alarm values ​​and the endpoint of the small temperature alarm value as a temperature alarm range; taking the area with a value less than the minimum temperature alarm value as a temperature alarm range; taking the area with a value greater than or equal to the maximum temperature alarm value as a temperature alarm range.

[0055] For example, the first temperature alarm value is 60°C, the second temperature alarm value is 65°C, the third temperature alarm value is 70°C, and the fourth temperature alarm value is 75°C; the temperature alarm ranges are: (0, 60°C), [60°C, 65°C), [65°C, 70°C), [70°C, 75°C), [75°C, ∞).

[0056] Step 104 , comparing the current temperature value with the temperature alarm range, and if the current temperature value is within the temperature alarm range, performing an operation corresponding to the temperature alarm range to adjust the output power of the aerosol generating device.

[0057] Specifically, the temperature alarm range is all the temperature alarm ranges obtained in step 103, and there are multiple temperature alarm ranges. The operation corresponding to the temperature alarm range in "performing the operation corresponding to the temperature alarm range to adjust the output power of the aerosol generating device" is: adjusting the output power of the current aerosol generating device to the product of the current output power and the preset coefficient; different temperature alarm ranges correspond to different preset coefficients. It is worth noting that the output power of the aerosol generating device is adjusted based on the output power of the current atomizing device.

[0058] In some examples, the temperature alarm value includes a first temperature alarm value, a second temperature alarm value, a third temperature alarm value, and a fourth temperature alarm value; the temperature alarm range includes a first alarm range, a second alarm range, a third alarm range, a fourth alarm range, and a fifth alarm range; the preset coefficient includes a first percentage, a second percentage, a third percentage, a fourth percentage, and a fifth percentage;

[0059] If the current temperature value is within the temperature alarm range, the operation corresponding to the temperature alarm range is performed, including: if the current temperature value is within the first alarm range, the output power is controlled to be adjusted to the first percentage of the current output power; if the current temperature value is within the second alarm range, the output power is controlled to be adjusted to the second percentage of the current output power; if the current temperature value is within the third alarm range, the output power is controlled to be adjusted to the third percentage of the current output power; if the current temperature value is within the fourth alarm range, the output power is controlled to be adjusted to the fourth percentage of the current output power; if the current temperature value is within the fifth alarm range, the output power is controlled to be adjusted to the fifth percentage of the current output power. Wherein, the first alarm range, the second alarm range, the third alarm range, the fourth alarm range and the fifth alarm range have no intersection with each other.

[0060] In some examples, the first percentage, the second percentage, the third percentage, the fourth percentage and the fifth percentage are different. Different alarm ranges represent different preset coefficients, showing a situation where the preset coefficient of output power is flexibly adjusted according to power.

[0061] In some examples, the first temperature alarm value is 60°C, the second temperature alarm value is 65°C, the third temperature alarm value is 70°C, and the fourth temperature alarm value is 75°C; the first alarm range is (0°C, 60°C), and the first percentage is 100%; the second alarm range is [60°C, 65°C), and the second percentage is 95%; the third alarm range is [65°C, 70°C), and the third percentage is 90%; the fourth alarm range is [70°C, 75°C), and the fourth percentage is 85%; the fifth alarm range is [75°C, ∞), and the fifth percentage is 0%.

[0062] In the specific implementation, during the output of the aerosol generating device, when the main control MCU detects that the temperature of the temperature sensor on the main control board exceeds the first temperature alarm value of 60°C, the output power is reduced to 95% of the current output power and the output is maintained. If the temperature continues to rise and exceeds the second temperature alarm value of 65°C, the output power is further reduced to 90% of the current output power and the output is maintained. If the temperature continues to rise and exceeds the third temperature alarm value of 70°C, the output power is further reduced to 85% of the current output power. If the temperature continues to rise and eventually exceeds the fourth temperature alarm value of 75°C, the output is shut down, the output power is reduced to 0% of the current output power, and the corresponding prompt is output for alarm.

[0063] In some examples, the preset period T is directly used as a detection period for step 102, so as to achieve the purpose of cyclic detection as a whole and improve the accuracy of overall detection and adjustment; that is, step 102 is performed once every T period to detect the current temperature value of the main control board, and then the temperature detection and aerosol atomizer output power adjustment within the period are performed. Usually, the preset period T is set to 160ms.

[0064] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.

[0067] In some examples, the aerosol generating device safety control module further includes an input unit 205, wherein the input unit 205 is used to input a temperature alarm value.
