[0029] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0031] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0032] As shown in Figure 1, an embodiment of the present application provides a heat-not-burn smoking device, which may include: a heating body 10, an airflow device 30 and a control device 20; wherein the smoking device has an airflow channel, which is used to connect an aerosol-generating substrate (such as a cigarette or a cigarette cartridge) with the outside world, and the aerosol generated by the aerosol-generating substrate can be inhaled into the mouth through the airflow channel through the user's inhalation.

[0033] The heating element 10 is used to heat an aerosol-generating substrate (e.g., a cigarette or a cigarette cartridge) to generate an aerosol that flows into the airflow channel. The heating element 10 can be a resistive heating element 10 or an electromagnetic heating element 10. This application uses a resistive heating element 10 as an example and does not limit the specific form of the heating element 10.

[0034] The airflow device 30 is used to generate airflow in the airflow channel. The airflow device 30 can be implemented in available forms such as an air pump, a fan motor, etc., and the present application does not limit the specific form of the airflow device 30.

[0035] The control device 20 is used to control the heating of the heating element 10 and the operation of the airflow device 30. In the process of controlling the heating element 10 to heat up to a preset operating temperature, the airflow device 30 is controlled to generate airflow at a relatively low temperature to discharge residual water vapor in the airflow channel and water vapor generated by the aerosol-generating matrix, and other impurities. The airflow device 30 is then controlled to stop operating, maintaining the heating element 10 at the operating temperature, heating the aerosol-generating matrix to generate aerosol. The control device 20 can be implemented using one or more processing devices, such as an MCU or FPGA.

[0036] It should be noted that the operating temperature of the heating element 10 is determined by the atomization temperature of the specific aerosol generating substrate, and is generally 200° C.-260° C. In this embodiment of the application, the aerosol generating substrate is a cigarette, and the corresponding operating temperature of the heating element 10 is 200° C. as an example.

[0037] In some embodiments, as shown in FIG. 1 , the control device 20 of the smoking article airflow device 30 provided in the present application may include: a heating control module 21 , a detection module 22 and an airflow control module 23 .

[0038] The heating control module 21 is used to obtain user-triggered heating instructions and control the heating element 10 to heat. In some embodiments, it is also used to obtain a stop heating instruction and control the heating element 10 to stop heating. The stop heating instruction can be user-triggered, such as when the user releases the ignition key, or it can be generated based on the control device 20 responding to a preset event, such as a fixed trigger after a certain heating period.

[0039] The detection module 22 is used to obtain heating-related parameters of the heating element 10. The heating-related parameters may include at least one of heating duration, temperature, and resistance. For example, the detection module 22 may be implemented using a timing module, a temperature measurement module, a voltage and current measurement module, etc. For example, if the heating element 10 is a resistive heating element 10, the temperature of the heating element 10 can be obtained by obtaining or calculating the resistance of the heating element 10, such as using a TCR algorithm. Alternatively, the temperature can be measured using a temperature sensor, and the heating duration can be recorded using a timer.

[0040] The airflow control module 23 is used to determine whether the heating-related parameters meet the first preset condition. If the heating-related parameters meet the first preset condition, the airflow device 30 is controlled to operate at the first preset power parameter and generate airflow.

[0041] If the heating-related parameter does not satisfy the first preset condition, the airflow control device 30 stops working.

[0042] When the heating-related parameters meet the first preset condition, the temperature of the heating element 10 is lower than its operating temperature.

[0043] For example, the heating element 10 is configured to heat from room temperature to 200°C within 20 seconds. In this case, the first preset condition may be that the heating time is 8-12 seconds after the heating element 10 begins heating, or that the temperature of the heating element 10 is 100-150°C. When the first preset condition is met, the airflow control device 30 operates to generate airflow in the airflow channel, and the airflow discharges non-useful atomized matter such as water vapor in the airflow channel. When the temperature exceeds 150°C or the heating time exceeds 12 seconds, the airflow control device 30 stops operating.

[0044] That is to say, the first preset condition is determined based on the time and temperature of the smoking device being heated to the working temperature once. Airflow is generated during the heating process of the heating element 10 to effectively discharge water vapor and impurities, providing a better user experience.

[0045] The specific process of the control method of the smoking device or the control device 20 is described below. As shown in Figures 2 and 3, the embodiment of the present application provides a control method of the airflow device 30 of the smoking device, which may include the following steps:

[0046] Step 1: Obtain a heating instruction triggered by the user and control the heating element 10 to heat.

[0047] For example, the user can trigger a heating instruction through a button or touch screen, and the heating control module 21 controls the heating of the heating element 10 according to the preset heating curve or heating parameters (corresponding to the working temperature and the preset heating time to the working temperature), starting from room temperature or a lower temperature to the preset working temperature.

[0048] Step 2: Obtain heating-related parameters of the heating element 10 and determine whether the heating-related parameters meet a first preset condition. The heating-related parameters may include at least one of heating duration, temperature, and resistance. When the heating-related parameters meet the first preset condition, the temperature of the heating element 10 is lower than the operating temperature. This embodiment of the present application is described using the heating-related parameters as heating duration and / or temperature.

[0049] For example, during the heating process of the heating element 10, the detection module 22 continuously detects or detects the heating-related parameters of the heating element 10 at preset intervals, the airflow control module 23 obtains the heating-related parameters of the heating element 10, and determines in real time whether the heating-related parameters meet the first preset conditions.

[0050] In some embodiments, the heating-related parameters may include heating duration and temperature. It should be noted that the heating duration in the embodiments of the present application may refer to the heating duration in a single heating cycle of the heating element.

[0051] In step 2, determining whether the fever-related parameters meet the first preset condition may include:

[0052] Step 210: Determine whether the heating time of the heating element 10 is within a first preset time range, and / or determine whether the temperature of the heating element 10 is within a first preset temperature range; the maximum value of the first preset temperature range is less than the operating temperature of the heating element 10.

[0053] Step 220: If the heating time of the heating element 10 is within the first preset time range, and / or the temperature of the heating element 10 is within the first preset temperature range, it is determined that the heating-related parameters meet the first preset condition.

[0054] Step 230: If the heating time of the heating element 10 is not within the first preset time range, and the temperature of the heating element 10 is not within the first preset temperature range, it is determined that the heating-related parameters do not meet the first preset condition.

[0055] As shown in FIG4 , the airflow device 30 can be set to operate during the heating stage of the heating element 10. Whether the airflow device 30 needs to operate can be determined based on the temperature of the heating element 10, or based on the heating time of the heating element 10. In other words, when the temperature Tf of the heating element 10 is between T1 and T2, and / or when the heating time tf of the heating element 10 is between t1 and t2, it can be considered that the heating-related parameters of the heating element 10 meet the first preset condition. The first preset time range is t1-t2, and the first preset temperature range is T1-T2.

[0056] In some embodiments, the maximum value T2 of the first preset temperature range is less than the operating temperature Tf of the heating element 10; and / or, the heating element 10 is configured to heat up to the operating temperature within a preset heating time, and the first preset time range is less than the preset heating time.

[0057] Step 3: If the heating-related parameters meet the first preset conditions, control the airflow device 30 to operate at the first preset power parameters and generate airflow.

[0058] As shown in Figure 4 , for example, if the heating element 10 is configured with a preset heating time of 20 seconds and an operating temperature of 200°C, the corresponding first preset temperature range (T1-T2) can be 100°C-150°C, and the first preset time range (t1-t2) can be 8 seconds-12 seconds. When the heating parameters of the heating element 10 meet the first preset conditions, the airflow control device 30 is activated.

[0059] Step 4: If the heating-related parameters do not meet the first preset condition, the airflow device 30 is controlled to stop working.

[0060] When the first preset condition is met, the airflow device 30 is controlled to operate, generating airflow in the airflow channel, which expels non-useful atomized matter such as water vapor from the airflow channel. When the temperature exceeds 150°C or the heating time exceeds 12 seconds, the water vapor has been completely expelled and a small amount of atomized matter begins to atomize, and the airflow device 30 can be controlled to stop operating.

[0061] In some embodiments, as shown in FIG3 , in step 3, controlling the airflow device 30 to operate at a first preset power parameter and generate airflow may include:

[0062] Step 310: Calculate a first operating power corresponding to the current heating-related parameters according to the current heating-related parameters.

[0063] In some embodiments, calculating the first operating power corresponding to the current heating-related parameters according to the current heating-related parameters may include:

[0064] A first operating power corresponding to the current heating-related parameters is calculated based on the current heating-related parameters and using a preset discrete power parameter or a preset first power curve. In some embodiments, as the heating duration increases or the temperature rises, the corresponding first operating power at least does not increase, and may be in a decreasing state.

[0065] In these embodiments, when the first operating power is calculated using a preset discrete power parameter, the airflow device 30 corresponds to a plurality of consecutive preset operating cycles, each of which corresponds to a first operating power. The preset operating cycles are divided according to the change in the heat-related parameter. The preset operating cycles can be divided according to the change in temperature, with one operating cycle for every 10°C, or according to the change in time, with one operating cycle for every 2 seconds.

[0066] The discrete power parameters can be represented by [Fn, Pn], where Fn represents a heating-related parameter, which can be the heating duration t or the temperature T, and Pn represents the power of the airflow device 30. The discrete power parameters for multiple working cycles are {[F0, P0], [F1, P1], ..., [Fn, Pn]}, where each working cycle corresponds to F0-F1, F1-F2, ...

[0067] For example, within the operating range of the airflow device 30, different operating cycles can operate at different power levels. For example, when the first preset time range is 8s-12s, the operating cycle can be divided into multiple operating cycles, such as 8s-9s, 9s-10s, 10s-11s, and 11s-12s, respectively, and the airflow device 30 can be driven to operate at 100%, 90%, 80%, and 70% of the maximum power. Alternatively, when the first preset temperature range is 100°C-150°C, the operating cycles can be divided into 100°C-110°C, 110°C-120°C, 120°C-130°C, and 130°C-150°C, respectively, and the airflow device 30 can be driven to operate at 100%, 90%, 80%, and 70% of the maximum power. The preset operating cycles can be evenly divided or unevenly divided.

[0068] In these embodiments, when the preset first power curve is used to calculate the first operating power, the first operating power is calculated according to the following formula;

[0069] PF = P(F);

[0070] Where PF is the first operating power, P(F) is the function corresponding to the first power curve, and F is a heat-related parameter. For example, P(F) can be a linear function, a quadratic function, or other functions. For example, it can be a function that constructs power-temperature or power-heating duration.

[0071] Step 320 : Determine a first duty cycle corresponding to the first operating power according to the first operating power and the maximum operating power of the airflow device 30 .

[0072] Step 330 : Control the airflow device 30 to operate according to the first duty cycle.

[0073] In some embodiments, when the airflow device 30 is implemented as a fan motor, power control can be achieved by controlling current or voltage, or by adjusting the duty cycle. However, for airflow devices 30 such as air pumps, overall power adjustment can only be achieved by controlling the operating frequency, that is, by adjusting the duty cycle. Since this embodiment uses an air pump, operating power must be controlled by varying the duty cycle.

[0074] For example, the maximum power of the air pump is to work once in 0.2 seconds, and it can work 5 times in 1 second. Assuming that the calculated first working power is adjusted to 60% of the maximum power, the first duty cycle is 60%, which means that the air pump needs to work 3 times in 1 second, that is, there is 0.4 seconds of inactivity in 1 second.

[0075] Of course, the above values ​​are just examples. Regardless of whether it is a motor or an air pump, the same can be achieved by adjusting the duty cycle. This is because as the temperature rises and the airflow device works, the water vapor and impurities in the smoking device are gradually discharged. Therefore, it is not necessary for the airflow device to operate at maximum power throughout the entire process. When the temperature approaches the operating temperature, the user begins to pay attention to the smoking device or has already placed it in their mouth. Therefore, using a low-power airflow device at this time can also reduce noise and further improve the user experience.

[0076] In some embodiments, as shown in FIG5 , after the heating element 10 stops heating, water vapor is also generated during the temperature drop of the heating element 10 and the cigarette, and the water vapor can also be removed by the airflow device 30. After the airflow device 30 stops working, step 5 can also be included:

[0077] Step 510: Control the heating element 10 to continue heating up to the operating temperature.

[0078] Step 520: Get a heating stop instruction and control the heating element 10 to stop heating.

[0079] Step 530: Determine whether the heating-related parameters of the heating element 10 in the cooling stage meet the second preset condition.

[0080] Step 540: If the second preset condition is met, control the airflow device 30 to operate at the second preset power parameter.

[0081] Step 550: If the second preset condition is not met, the airflow device 30 is controlled to stop working.

[0082] In step 530, the following may be included:

[0083] Step 531: Determine whether the heating time of the heating element 10 is within a second preset time range, and / or determine whether the temperature of the heating element 10 is within a second preset temperature range; the maximum value of the second preset temperature range is less than the operating temperature of the heating element 10.

[0084] Step 532: If the heating time of the heating element 10 is within the second preset time range, and / or the temperature of the heating element 10 is within the second preset temperature range, it is determined that the heating-related parameters meet the second preset condition.

[0085] Step 533: If the heating time of the heating element 10 is not within the second preset time range, and the temperature of the heating element 10 is not within the second preset temperature range, it is determined that the heating-related parameters do not meet the second preset condition.

[0086] For example, as shown in FIG5 , the second preset temperature range may be 150° C.-100° C., and the second preset time range may be 38 seconds-42 seconds.

[0087] Since the airflow device is controlled to work during heating and cooling respectively, the above-mentioned step 5 can refer to the relevant limitations of steps 1 to 4 of the above-mentioned embodiment, the specific limitations of the second preset condition can refer to the limitations of the first preset condition, and the specific judgment method can also refer to the corresponding embodiment of the first preset condition; similarly, the second preset power parameter can also refer to the limitations of the first preset power parameter, and will not be repeated here.

[0088] The control method provided in the embodiment of the present application, the specific process of each step can be executed by the corresponding module in the control device, that is, the specific process of each step can be the functional description of each module in the aforementioned control device embodiment, and will not be repeated here.

[0089] In summary, the embodiments of the present application provide a control method, device, and smoking device for the airflow device 30 of a smoking device. During the heating stage of the heating element 10, before the temperature reaches the operating temperature, the airflow device 30 is controlled to operate to generate airflow to discharge water vapor in the air path of the smoking device. When the heating element 10 is at the operating temperature, the airflow device 30 does not operate, and no noise is generated or useful atomized matter is discharged before the user inhales, thereby improving the user's experience.

[0090] The same method can also be used to remove water vapor during the cooling stage to prevent the water vapor generated by cooling from accumulating in the gas channel.
