Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular provides a heating control method and an atomization device for an atomization device. Background Art

[0002] An atomization device is a device that heats and atomizes an aerosol matrix through a heating element to generate an aerosol for a user to inhale; during the atomization process, the heating temperature of the heating element has a direct impact on the atomization effect and the inhalation taste. In the existing field of atomization devices, some devices use the Temperature Coefficient of Resistance (TCR) to achieve temperature control. The temperature coefficient of resistance represents the relative change in resistance value when the temperature changes by 1 degree.

[0003] The current temperature control technology of atomization devices calculates the resistance change of the heating element through the host chip to convert the temperature information. After the resistance value corresponding to the set heating temperature is reached when the heating element starts heating and reaches the temperature, the chip will reduce the output power to prevent the resistance value from rising further, that is, the temperature from rising further. The chip adjusts the output power through a series of voltage boosts and voltage drops during the entire heating process, and finally maintains the resistance change of the heating element at the resistance value corresponding to the set heating temperature. However, the temperature coefficient of resistance of some heating materials is non-linear, and the temperature coefficient of resistance varies greatly at different temperatures, especially when the temperature rises, the temperature coefficient of resistance changes greatly. It is difficult to convert the temperature through the resistance change in this stage, so it is impossible to use the temperature coefficient of resistance for temperature control during the heating-up stage. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a heating control method and an atomization device for an atomization device, aiming to solve the problem that the temperature coefficient of resistance of the heating element of the existing atomization device has a non-linear relationship and temperature control cannot be achieved during the heating-up stage.

[0005] To achieve the above purpose, the technical solution adopted in this application is as follows:

[0006] In a first aspect, the embodiments of this application provide a heating control method for an atomization device, including the following steps: S1: Obtain a heating instruction triggered by a user; S2: Control the heating component to enter a preheating stage; within a total preheating duration of N0 seconds, control the heating component of the atomization device to heat at a set power value so that the temperature of the heating component reaches the atomization temperature; S3: Control the heating component to enter an automatic constant temperature stage; monitor the current resistance of the heating component, and obtain the current temperature of the heating component according to the reference resistance and the resistance temperature coefficient of the heating component at the atomization temperature; compare the current temperature with the atomization temperature, and adjust the power of the heating component to keep the heating component at the atomization temperature.

[0007] The beneficial effect of the heating control method of the atomization device of the present application is that: in the preheating stage, the heating component is heated by a preset power value, specifically by controlling the heating component to directly heat the preset time with the set first power and the second power respectively to reach the atomization temperature, and the heating power in the two stages is a fixed value; therefore, the heating component of the present application uses a set power curve to heat the heating component during the heating process, and the temperature control is more accurate to avoid temperature overshoot. In the constant temperature stage, the resistance temperature coefficient of the heating component is stable at the atomization temperature, so the resistance temperature coefficient is used for temperature control to effectively maintain the temperature of the heating component at the atomization temperature; therefore, the atomization device of the present application uses different methods to control the temperature of the heating component at different stages, the design is ingenious, and the temperature control is more reasonable and accurate.

[0008] In some embodiments, the step of controlling the heating component to enter the preheating stage includes:

[0009] Control the heating component to heat at the first power for N1 seconds until the temperature of the heating component reaches the preheating temperature;

[0010] The power of the heating component is reduced to the second power, and the heating component is controlled to heat at the second power for N2 seconds, so that the temperature of the heating component is reduced to the atomization temperature.

[0011] By adopting the above technical solution, the preheating stage can be understood as including a high-temperature heating stage and a low-temperature heating stage. In the high-temperature stage, the heating component is controlled to heat at the first power for N1 seconds to the preheating temperature, which is mainly used to release the moisture and volatile components in the aerosol-generating matrix. The pre-high-temperature treatment enables the aerosol-generating matrix to form rich smoke and aroma in the subsequent low-temperature stage. In the low-temperature stage, the heating component is controlled to heat at the second power for N2 seconds to the temperature, which is mainly used to release nicotine and other components that are conducive to suction in the aerosol-generating matrix; making the user's subsequent suction process smoother.

[0012] In some embodiments, the preheating temperature ranges from 270-330°C;

[0013] In some embodiments, the atomization temperature ranges from 250-300°C.

[0014] In some embodiments, step S2 includes: setting the total preheating time N0 to a time range of 10-25 seconds; N1+N2=N0.

[0015] By adopting the above technical solution, the total preheating time is set according to the usage habits, and the user does not need to wait too long; N1 and N2 can be reasonably allocated according to the total preheating time.

[0016] In some embodiments, N0 = 20s; N1 = 8s; N2 = 12s.

[0017] In some embodiments, in the step of controlling the heating component to enter the preheating stage, it includes: the atomizing device has at least two gears of output power for the heating component, the first power adopts the maximum output power; the second power is configured as one of the output powers less than the first power.

[0018] By adopting the above technical solution, the first power is the maximum output power of the atomizing device for the heating component, which effectively improves the heating speed of the heating component and can shorten the preheating duration.

[0019] In some embodiments, the first power is configured as 16w; the second power is configured as 8w.

[0020] In some embodiments, in the step of controlling the heating component to enter the automatic constant temperature stage, it includes: the atomizing temperature T0, the current temperature T2, the current resistance R1, the reference resistance R0 of the heating component at the atomizing temperature T0, and the resistance temperature coefficient α satisfy the relational expression: R1 = R0(1 + α(T2 - T0)).

[0021] By adopting the above technical solution, after the heating component finishes preheating, at the atomizing temperature, the resistance temperature coefficient of the heating is at a stable value, and then the temperature can be stably controlled at the atomizing temperature by using TCR.

[0022] In some embodiments, the atomizing device further includes a control module electrically connected to the heating component, and the control module includes a start module, a control module, and a storage module;

[0023] In the step of obtaining the heating instruction triggered by the user, it includes: the start module is configured to generate a heating instruction under the operation of the user.

[0024] By adopting the above technical solution, the start module can adopt common functional modules such as a button module or a touch module, which is convenient for user operation.

[0025] In some embodiments, the atomizing device has an engineering debugging stage, and the debugging stage includes:

[0026] According to the aerosol generation matrix that the heating component needs to heat, obtain the preheating temperature and the atomizing temperature;

[0027] The aerosol - generating matrix is heated from the cold state at a first power, and a heating - up curve of the temperature change over time when the heating component is heated at the first power is collected. According to the heating - up curve, the duration N1 required for the heating component to be heated to the pre - heating temperature at the first power is obtained.

[0028] N2 is obtained based on the set total pre - heating duration N0 and N1, and the second power required to reduce the heating component from the preset temperature to the atomization temperature within the heating duration of N2 is measured.

[0029] Each parameter is written into and stored in the storage module for the control module to call during the process from step S1 to S0.

[0030] In some embodiments, the heating component uses a ceramic heater.

[0031] By adopting the above - mentioned technical solution, the resistance temperature coefficient of ceramic materials is usually non - linear. When the temperature of ceramic materials changes, the change in its resistance value does not simply increase or decrease proportionally, but shows a complex non - linear relationship; and the TCR gap is large at different temperatures, so it is impossible to obtain an accurate temperature through the change in resistance value. Therefore, the existing TCR temperature - control method is not applicable in the pre - heating and heating - up stage.

[0032] In a second aspect, the present application also provides an atomizing device, including a heating component and a control module; the heating component is configured to heat the aerosol matrix; the control module controls the heating component to heat based on the above - mentioned heating control method.

[0047] In the current temperature control technology of atomizing devices, the main control chip calculates the resistance change of the heating element to convert the temperature information. When the heating element reaches the resistance value corresponding to the set heating temperature, the chip will reduce the output power to prevent the resistance value from rising further, that is, the temperature from rising further. The chip will adjust the output power through a series of boosting and bucking to keep the resistance change of the heating element at the resistance value corresponding to the set heating temperature. However, for some heating materials, the temperature coefficient of resistance is non-linear, and the difference in the temperature coefficient of resistance at different temperatures is large, especially when the temperature rises, the change in the temperature coefficient of resistance is large, making it difficult to convert the temperature through the resistance change. Therefore, it is impossible to use the temperature coefficient of resistance for temperature control during the heating-up stage.

[0048] Based on this, to solve the above problems, the present application designs a heating control method for an atomizing device. During the preheating stage, the heating component is directly heated at a set first power and second power for a preset duration respectively to reach the atomizing temperature, that is, the heating component is heated up using a set power curve, and the heating-up control is more accurate, avoiding temperature overshoot. During the constant-temperature stage, the temperature coefficient of resistance is used for temperature control to effectively keep the temperature of the heating component at the atomizing temperature. Different methods are used to control the temperature of the heating component at different stages, with a clever design and more reasonable and accurate temperature control.

[0049] Reference Figure 1, this application provides an atomization device, which includes a heating component 10 and a power supply component for supplying power to the heating component; the atomization device is used to accommodate an aerosol-forming substrate in a liquid, solid, gaseous or gel state, and after the heating component is powered on, it heats the aerosol-forming substrate and controls the heating temperature to a corresponding operating temperature (the atomization temperature corresponding to the aerosol-forming substrate) to achieve atomization.

[0050] The atomization device uses a resistive heating component 10 for heating, and the resistance of the heating component 10 is affected by temperature.

[0051] In some embodiments, the atomization device can be a heat-not-burning device, etc. Heat Not Burning (abbreviated as HNB) is a new type of product that combines a heating module and a cigarette stick. It is a "low-temperature cigarette" designed with the idea of "only heating without burning". Specifically, the aerosol-forming substrate 2 is similar in shape to a cigarette stick and contains tobacco products; the processed aerosol-forming substrate is heated to a certain temperature at a low temperature (far lower than the combustion temperature of traditional cigarettes) by the heating component, so that the aerosol-forming substrate bakes out the flavor and is closer to traditional cigarettes in terms of taste and form.

[0052] In still other embodiments, the atomization device can also be an electronic atomization device, which stores a liquid aerosol-forming substrate.

[0053] Specifically, referring to Figure 1 , the atomization device further includes a control module, and the control module is used to control the heating of the heating component 10; the control module includes a start module 20, a control module 30 and a storage module 40. It can be understood that the start module 20 is configured to generate a heating instruction under the operation of the user; the start module 20 can adopt common functional modules such as a button module or a touch module, and the user can generate a heating instruction by manually operating the start module 20.

[0054] After receiving the heating instruction, the control module 30 is used to control the heating of the heating component 10 and the heating parameters; it can be understood that the heating parameters can include power parameters, current parameters, voltage parameters, etc., and the parameters of each heating stage are stored in the storage module 40, and the control module 30 can call the data stored in the storage module 40; exemplarily, the control module 30 can adopt a logic processor device with data processing and computing capabilities, such as an MCU or other processor devices.

[0055] Referring to Figure 2 , in some embodiments, the heating control method of the atomization device includes the following steps:

[0056] S1. Obtain a heating instruction triggered by the user;

[0057] Understandably, the activation module 20 can be a button module or a touch module provided outside the atomization device for easy manual operation by the user; after the user touches / presses the activation module 20, the control module 30 obtains the heating instruction triggered by the user through the activation module 20, and under the trigger of the heating instruction, the control module 30 controls the heating component 10 to start heating according to the set parameters through the setting in the storage module 40.

[0058] S2. Control the heating component 10 to enter the preheating stage; within the preset total duration of N0 seconds, control the heating component 10 to heat at a preset power value so that the temperature of the heating component 10 reaches the atomization temperature T0.

[0059] Understandably, after obtaining the heating instruction triggered by the user, the heating component 10 starts and enters the preheating stage; the purpose of the preheating stage is to increase the temperature of the heating component 10 so as to be able to fully heat the aerosol-forming substrate, fully release the smoke during the heating process, and at the same time reduce the generation of harmful substances, thereby producing a better atomization effect and taste.

[0060] Reference Figure 3 , specifically, the preheating stage sequentially includes the following heating steps:

[0061] S201: Control the heating component to heat at the first power P1 for N1 seconds until the temperature of the heating component 10 reaches the preheating temperature T1.

[0062] Specifically, the preheating temperature T1 is determined according to the composition of the aerosol-forming substrate (according to the moisture content, nicotine content, and tobacco density). To ensure that at the preheating temperature T1, the moisture and volatile components in the aerosol-forming substrate can be released to form rich fog and aroma.

[0063] In some embodiments, the temperature range of the preheating temperature T1 is between 270 - 330 °C.

[0064] In still other embodiments, the atomization device has at least two levels of output power for the heating component 10, wherein the first power P1 is configured as the maximum output power of the atomization device for the heating component 10, effectively improving the heating rate of the heating component 10 and being able to shorten the preheating duration, enhancing the user experience.

[0065] S202: Reduce the power of the heating component to the second power P2, and control the heating component to heat at the second power P2 for N2 seconds to reduce the temperature of the heating component to the atomization temperature T0.

[0066] Specifically, the aerosol generating matrix is ​​first heated at the preheating temperature T1 mainly to release the moisture and volatile components in the aerosol generating matrix; however, the preheating temperature T1 is relatively high, and the aerosol generating matrix cannot be continuously heated at the preheating temperature T1, which poses a risk of decomposing harmful substances such as aldehydes, and will cause the temperature of the generated aerosol gas to be too high, resulting in a burning sensation and irritation, causing the user's inhalation experience to decrease.

[0067] Therefore, after the temperature of the heating component 10 rises to the preheating temperature T1, the control module 30 controls the power of the heating component 10 to be reduced from the first power P1 to the second power P2 through the heating parameters set in the storage module 40. The heating component heats at the second power P2 for N2 seconds to reduce the temperature of the heating component 10 to the atomization temperature T0.

[0068] Specifically, at the atomization temperature T0, nicotine and other components that are conducive to smoking in the aerosol generation matrix are slowly released; at the same time, the production of harmful substances due to high-temperature combustion is avoided, for example: the production of harmful substances such as tar, carbon monoxide and heavy metals can be reduced.

[0069] In some embodiments, the atomization temperature T0 ranges from 250°C to 300°C.

[0070] Specifically, the atomizing device has at least two output power levels, the first power P1 is configured as the maximum output power of the atomizing device, and the second power P2 is configured as an output power level of the atomizing device that is less than the first power P1, for example: second output power level / third output power level.

[0071] The preheating stage can be understood as including a high-temperature heating stage and a low-temperature heating stage. In the high-temperature stage, the heating component 10 is controlled to heat N1 seconds at the first power P1 to the preheating temperature T1, which is mainly used to release the moisture and volatile components in the aerosol-generating matrix. The pre-high-temperature treatment enables the aerosol-generating matrix to form rich smoke and aroma in the subsequent low-temperature stage, which can provide a better taste and satisfaction. In the low-temperature stage, the heating component 10 is controlled to heat N2 seconds at the second power P2 to the atomization temperature T0, which is mainly used to release nicotine and other components that are conducive to suction in the aerosol-generating matrix.

[0072] Therefore, the heating component 10 can accurately control the temperature by heating for a preset time at different heating powers, so that the heating component 10 performs a preheating operation from high temperature to low temperature, making the user's subsequent puffing process smoother, reducing harmful substances (tar, carbon monoxide and heavy metals, etc.) produced by high-temperature combustion, reducing burning sensation and irritation, and effectively improving the puffing experience.

[0073] Understandably, N1 + N2 = N0, that is, the total preheating process includes a high-temperature stage in which the heating component 10 is heated to the preheating temperature T1 at the first power P1 for N1 seconds in sequence, and a low-temperature stage in which it is heated to the temperature T0 at the second power P2 for N2 seconds.

[0074] In some embodiments, the range of N0 is 10 - 25S, so that users do not need to wait too long; the range of N1 is 4 - 15s, and the range of N2 is 6 - 18s.

[0075] Preferably, N0 = 20s, that is, the total preheating duration is 20s; N1 is 8s, the first power P1 is 16w, and the first power P1 is the maximum output power of the atomizing device, that is, after the heating component 10 starts to heat up, it is heated at a power of 16w for 8 seconds; N2 is 12 seconds, and the second power P2 is 8w, that is, after the heating component 10 is heated at a power of 16w for 8s, it switches to be heated at a power of 8w for 12 seconds.

[0076] In some embodiments, the heating component 10 uses a ceramic heater, and the temperature of the heating component 10 is the ceramic temperature. Most of the current resistance heating components of atomizing devices control the temperature according to the TCR (Temperature Coefficient of Resistance) algorithm. However, the resistance temperature coefficient of ceramic materials is usually non-linear. When the temperature of ceramic materials changes, the change in its resistance value is not simply proportional increase or decrease, but shows a complex non-linear relationship; and the TCR gap is large at different temperatures, so the accurate temperature cannot be obtained through the change in resistance value. Therefore, the existing TCR temperature control method is not applicable in the preheating stage.

[0077] In this application, during the preheating process, heating is carried out using a set power curve, that is, the atomizing temperature T0 can be achieved by directly controlling the heating component 10 to be heated at the set first power P1 and second power P2 for the preset duration respectively. The heating power in the two stages is a fixed value. Therefore, this application does not adopt the TCR temperature control method in the preheating stage. The heating component 10 directly uses the constant first power P1 and second power P2 to stably rise to the atomizing temperature T0, effectively avoiding the problem of unstable temperature control of the heating component 10 in the preheating stage.

[0078] In some embodiments, the atomizing device further includes an engineering debugging stage.

[0079] Understandably, the engineering debugging stage is before the atomization device leaves the factory to set the heating parameters for each stage of the atomization device. During the engineering stage of product design and debugging of the atomization device of the present application, by using an external temperature measuring instrument, such as an infrared temperature measuring instrument, the values of parameters such as N0, N1, N2, T1, T0, the first power P1, and the second power P2 are measured and debugged. Each heating parameter is stored in the storage module 40 for the control module 30 to call during the heating process.

[0080] Specifically, according to the aerosol-forming substrate to be heated by the heating assembly 10, the preheating temperature T1 and the atomization temperature T0 are obtained. The first power P1 is configured as the maximum output power of the current atomization device. The aerosol-forming substrate is heated from a cold machine (the atomization device is in a normal temperature state) at the first power P1. After multiple heating operations, the heating curve of the temperature change of the heating assembly 10 over time when heated at the first power P1 is collected. According to the heating curve, the duration N1 required for the heating assembly 10 to be heated to the preheating temperature T1 at the first power P1 is obtained.

[0081] After determining the duration N1, according to the set preheating duration N0, N2 = N0 - N1 can be obtained. Further, an infrared temperature measuring instrument is used to measure the heating power required for the heating assembly 10 to stably decrease from T1 to T0 during the heating duration of N2. This power is the second power P2.

[0082] The values of the parameters such as N0, N1, N2, the preheating temperature T1, the atomization temperature T0, the first power P1, and the second power P2, which are debugged and obtained, are written and stored in the storage module 40 for the control module 30 to call during the use of the atomization device.

[0083] Understandably, the engineering debugging stage does not require user operation and is set before the device is sold out of the factory to make the process of the user sucking and using the atomization device simple and stable.

[0084] S3. Control the heating assembly 10 to enter the automatic constant temperature stage; monitor the current resistance of the heating assembly 10, and obtain the current temperature of the heating assembly 10 according to the reference resistance R0 and the temperature coefficient of resistance of the heating assembly 10 at the atomization temperature T0; compare the current temperature of the heating assembly with the atomization temperature, and adjust the power of the heating assembly to keep the heating assembly at the atomization temperature T0.

[0085] Specifically, in order to ensure that the aerosol-forming substrate is stably heated to generate smoke and enable the user to have a smooth suction; after the preheating is completed, the heating assembly 10 needs to be heated at a constant atomization temperature T0.

[0086] In this embodiment, the temperature coefficient of resistance (TCR) is first explained. The temperature coefficient of resistance refers to the ratio of the resistance value to the change in temperature. Different materials have different resistivity (i.e., temperature coefficient of resistance), and different temperatures will also change the resistivity of the same material. In materials science, TCR is usually used to reflect the degree to which the resistance of a material is affected by temperature. In the prior art, the temperature control function of the atomizing device determines the operating temperature of the heating component 10 according to the coefficient of change of the resistance value of the heating component 10 with temperature, so that the atomizing device can be controlled within the temperature range of environmental protection and will not have an adverse impact on the human body.

[0087] It can be understood that after the preheating stage ends, the heating component 10 is maintained at the atomizing temperature T0, and the temperature change is small, that is, the value of the temperature coefficient of resistance of the heating component 10 can be regarded as a fixed value. Therefore, in the automatic constant temperature stage, TCR can be used to control the temperature of the heating component 10 to be stable at the atomizing temperature T0.

[0088] In some embodiments, by measuring the resistance value of the heating component 10 and according to the temperature coefficient of resistance α, the current temperature of the heating component 10 can be calculated.

[0089] The formula is: R1 = R0(1 + α(T2 - T0))

[0090] Wherein,

[0091] R1: The resistance value of the heating component at the current temperature;

[0092] R0: The reference resistance of the heating component at the atomizing temperature T0;

[0093] α: The temperature coefficient of resistance of the heating component at the atomizing temperature T0;

[0094] T2: The current temperature; T0: The ideal atomizing temperature of the aerosol generating substrate.

[0095] Subsequently, through the above formula, the constant temperature stage includes the following detection steps:

[0096] S301: After the atomizing device monitors the resistance value of the current heating component 10 in real time, the current temperature T2 of the heating component 10 can be obtained through conversion. Compare T2 with T0, and accordingly adjust the power of the heating component so that the heating component 10 is stable at the atomizing temperature T0.

[0097] Specifically, when it is detected that the current temperature T2 < T0, the control module 30 controls the power of the heating component 10 to increase. For example, the heating parameters of the heating component 10 are adjusted, such as increasing the current or voltage of the circuit where the heating component 10 is located, until it is detected again that the current temperature T2 = T0, then the increase in the power of the heating component 10 is stopped. When it is detected that the current temperature T2 > T0, the control module 30 controls the power of the heating component 10 to decrease. For example, the heating parameters of the heating component 10 are adjusted, such as decreasing the current or voltage of the circuit where the heating component 10 is located, until it is detected again that the current temperature T2 = T0, then the decrease in the power of the heating component 10 is stopped.

[0098] In a specific embodiment of the present application, N0 = 20s, N1 = 8s, P1 = 16w, N2 = 12 seconds, P2 = 8w, T1 = 330 °C, T0 = 280 °C, and the TCR value of the heating component 10 at the atomization temperature T0 is 2300 PPM / °C.

[0099] In some other embodiments, in the automatic constant temperature stage of the atomization device, the control logic of the control module can also be directly set as: comparing R1 with R0, and accordingly adjusting the power of the heating component so that the heating component 10 is stabilized at the atomization temperature T0; specifically, when it is detected that the current temperature R1 < R0, the control module 30 controls the power of the heating component 10 to increase until it is detected again that the current temperature R1 = R0, then the increase in the power of the heating component 10 is stopped. When it is detected that the current temperature R1 > R0, the control module 30 controls the power of the heating component 10 to decrease until it is detected again that the current temperature R1 = R0, then the decrease in the power of the heating component 10 is stopped.

[0100] Subsequently, in the constant temperature stage of the atomization device, that is, when the user sucks and uses the atomization device, by adjusting the power applied to the heating component 10, the temperature of the heating component 10 is adjusted so that the temperature of the heating component 10 remains unchanged at the preset atomization temperature T0, realizing the function of automatic constant temperature of the atomization device of the present invention.
