[0048] One embodiment of this application discloses a control method applied to an electronic atomizing device. For example... Figure 1 As shown, the electronic atomizing device includes a heating module, a passive component 11, and an active component 12. The passive component 11 is used to store and transport the unheated heat-receiving body 13, and the active component 12 is used to receive the heated heat-receiving body 13 and drive the passive component 11 to rotate via the heated body 13. The heating module is used to heat the heat-receiving body to generate an aerosol. The heating module can be a contact or non-contact heating method, and the heating method includes, but is not limited to, electromagnetic induction heating, laser heating, microwave heating, and infrared radiation heating; this application does not impose any limitations on this. For example, the passive component 11 can be a passive wheel, and the active component 12 can be an active wheel.
[0049] In this embodiment, the heated body is a thin, flexible medium. The heated body includes a layered aerosol-generating matrix and a thermally conductive baseband. The baseband can be made of metal. The baseband can be located between the aerosol-generating matrix and the heating element in the heating module, and the baseband can be in contact with the heating element in the heating module. Optionally, the thickness of the heated body is 0.05mm-0.5mm. In other embodiments, the heated body may also consist only of the aerosol-generating matrix.
[0050] The aerosol generating matrix is used to generate aerosols by being heated by a heating element. Exemplarily, the aerosol generating matrix can be used to generate aerosols in a non-combustible manner. That is, the aerosol generating matrix is heated below its ignition point to generate aerosols. The aerosol generating matrix does not burn during the aerosol generation process. An electronic atomizing device is used to allow a user to inhale the aerosol generated by the aerosol generating matrix.
[0051] The aforementioned active component drives the heated element to move in a specific direction. After the user inhales, as... Figure 2 As shown, the active component removes the already heated object, i.e., the current suction medium 21, and moves the next medium to be heated 22 to the heating area. Figure 2 The direction of the middle arrow indicates the direction of movement of the heated body. (Reference) Figure 1 The electronic atomizing device also includes an atomizing chamber. The passive component, active component, heated element, and atomizing chamber are all housed in a sealed box. This sealed box is a structural component of the electronic atomizing device and is detachable from the device, allowing users to easily remove and replace it after all the heated elements have been inhaled. The atomizing chamber is used to hold the heated element to be heated.
[0052] The atomizing chamber refers to the space surrounding the heated area of the heated body inside the device. Its function is to guide the atomized aerosol to flow in the direction of the suction airflow. Because the heated body is baked at high temperature (e.g., baking temperature > 250℃) inside the atomizing chamber, the temperature inside the chamber will rise and fall accordingly as the suction time or the heating time is stopped.
[0053] like Figure 3 As shown, the control method provided in this embodiment includes the following steps:
[0054] S110, Obtain reference heating parameter values. In this embodiment, the heating parameter is the heating power. Specifically, it can be the average heating power over a time period, i.e., the average heating power within that time period. In this embodiment, the reference heating parameter value is the heating power under preset standard conditions and preset heating conditions. For example, the preset standard condition can be the first suction at an ambient temperature of 23°C. The preset heating condition can be that the heating duration for each suction is 1 second, and the temperature of the aerosol generation matrix needs to be controlled to rise to 300°C. The reference heating parameter value can be P0.
[0055] S120, establish the target relationship between the heat loss influencing factor and the heating parameter compensation value.
[0056] S130: Obtain the current impact factor value, and determine the current parameter compensation value based on the current impact factor value and the target relationship.
[0057] S140, determine the target heating parameter value based on the reference heating parameter value and the current parameter compensation value. The target heating parameter value is the sum of the reference heating parameter value and the current parameter compensation value.
[0058] S150 controls the heating module to heat the object to the target heating parameter value.
[0059] Specifically, according to the first law of thermodynamics, the change in the thermodynamic energy (internal energy) of a closed system is equal to the sum of the heat absorbed by the system from the environment and the work done by the environment on the system. Its mathematical expression is: ΔU = Q + W. In this formula, Q represents the heat absorbed by the system from the environment, W represents the work done by the environment on the system, and ΔU represents the change in the system's thermodynamic energy (internal energy). Where Q = c·m·Δt, m is the mass of the heated body, c is the specific heat capacity of the heated body, and Δt is the temperature change.
[0060] In other words, assuming the mass and specific heat capacity of the heated object remain constant, the temperature change of the heated object after heating is mainly affected by its initial temperature before heating, the heating power per unit time, and heat loss (carried away by airflow or absorbed by ambient temperature). That is, if the temperature uniformity of the heated object is indirectly controlled by the heating power per unit time, it is necessary to calculate the initial temperature of the heated object and the heat loss during the heating process, and then calculate the required compensation heating power based on these factors, thus forming a compensatory heating power control mechanism.
[0061] The initial temperature of the heated body is mainly affected by two factors:
[0062] Firstly, the ambient temperature surrounding the heated object. This ambient temperature includes the temperature of the atomizing chamber. In this embodiment, the ambient temperature surrounding the heated object is the temperature of the atomizing chamber.
[0063] Secondly, there is the cooling time of the heated body after being heated by the previous high-temperature medium. Specifically, during the current suction heating, the heat in its heating area is transferred to the heating area of the next suction through the metal base belt. After the suction ends, the heated body in the next suction heating area is moved to the heating area, and its temperature is rapidly cooled before the next suction.
[0064] The heat loss during the heating process is mainly affected by two factors:
[0065] Firstly, the ambient temperature around the heated object, i.e., the temperature of the atomizing chamber. The higher the ambient temperature, the less heat is lost from the heated object.
[0066] Secondly, the suction airflow velocity during the user's suction process. The suction airflow velocity affects the airflow speed at the inlet; the faster the airflow velocity, the faster the heat is carried away, and the more heat is lost from the heated body. Conversely, the slower the airflow velocity, the less heat is lost from the heated body.
[0067] As can be seen from the above analysis, the main influencing factors include: the ambient temperature of the heated body inside the electronic atomizing device, the cooling time of the heated body between two adjacent suction actions, and the suction airflow velocity. Therefore, the heat loss influencing factors include at least one of the above three influencing factors. In this embodiment, the heat loss influencing factors include the above three influencing factors. It should be noted that in other embodiments, the heat loss influencing factors may also include only one or any two of the above three factors, and the types of compensation values included in the heating parameter compensation values will also change accordingly. The corresponding technical solutions are also within the protection scope of this application.
[0068] In this embodiment, the heating parameter compensation values include a first compensation value, a second compensation value, and a third compensation value. The first compensation value corresponds to the ambient temperature. The second compensation value corresponds to the cooling time. The third compensation value corresponds to the suction airflow velocity. The first compensation value is denoted as Pb, the second compensation value as Pc, and the third compensation value as Pd. Pb, Pc, and Pd can all be positive or negative numbers. The current parameter compensation value is denoted as Pa, then Pa = Pb + Pc + Pd.
[0069] It should be noted that in step S120, the target relationship can be obtained by adding the calculation formulas corresponding to the first compensation value, the second compensation value, and the third compensation value. Step S130 directly calculates the current parameter compensation value based on the target relationship. The target relationship can also include the calculation formulas corresponding to the above three compensation values, and then calculate the parameter compensation values corresponding to the three heat loss influencing factors respectively through step S130, and add the parameter compensation values corresponding to the three heat loss influencing factors to obtain the current parameter compensation value.
[0070] The current impact factor value is the corresponding value of the aforementioned heat loss impact factor collected at the current moment. In step S130, the current impact factor value is used as the input parameter of the target relationship to calculate the current parameter compensation value. The target heating parameter value is obtained by adding the reference heating parameter value and the current parameter compensation value.
[0071] This embodiment employs a compensated heating power control method under power control heating. Based on the target relationship that characterizes the relationship between heat loss influencing factors and heating parameter compensation values, the current parameter compensation value is determined according to the current influencing factor value. The heating module is controlled to heat by using the adjusted heating parameter value, which is more accurate under the current heating conditions. This takes into account the influence of different conditions and factors, and adjusts the heating parameter output to ensure the consistency of medium heating under different suction conditions, improve the consistency of medium temperature control, and thus achieve better heating effect and product quality.
[0072] Another embodiment of this application discloses a control method applied to an electronic atomizing device. For example... Figure 4 As shown, this embodiment is based on the above. Figure 3 Based on the corresponding embodiment, step S120 includes:
[0073] S1201, acquire multiple sets of experimental data.
[0074] S1202, based on multiple sets of experimental data, the target relationship between the heat loss influencing factor and the heating parameter compensation value is obtained by fitting.
[0075] Among them, the above-mentioned multiple sets of experimental data include experimental data on the change of the first compensation value with the change of the ambient temperature of the heated body inside the electronic atomizing device, experimental data on the change of the second compensation value with the change of the cooling time of the heated body during the interval between two adjacent suction actions, and experimental data on the change of the third compensation value with the change of the suction airflow velocity.
[0076] Then, a fitting mathematical model can be used to fit the target relationship based on multiple sets of experimental data. The fitted relationship can also be used to validate the results in practical applications, and necessary adjustments can be made based on the actual performance. The fitting mathematical model can be linear, nonlinear, or a piecewise function. For example, the fitting mathematical model could be a linear regression model.
[0077] The process of establishing the target relationship is explained below:
[0078] Regarding the process of constructing the relationship between the ambient temperature of the heated body inside the electronic atomizing device and the corresponding first compensation value, if the ambient temperature of the heated body, i.e. the temperature of the atomizing chamber, can be obtained by measuring the ambient temperature of the heated body through a sensor, multiple sets of experimental data on the atomizing chamber temperature and heating power can be collected, and the relationship between the first compensation value and the atomizing chamber temperature can be obtained by fitting multiple sets of experimental data.
[0079] If the ambient temperature of the heated object, i.e. the temperature of the atomizing chamber, cannot be measured by the sensor, multiple sets of experimental data on the atomizing chamber temperature, the ambient temperature, and the heating power can be collected. The correlation between the atomizing chamber temperature and the ambient temperature can be obtained by fitting multiple sets of experimental data. After the ambient temperature is measured by the sensor, the atomizing chamber temperature can be calculated based on the above correlation. Then, based on the relationship between the fitted first compensation value and the atomizing chamber temperature, the first compensation value can be calculated.
[0080] In some optional embodiments, to more accurately represent the correlation between the atomizing chamber temperature and the ambient temperature, multiple sets of experimental data can be collected, including data on the atomizing chamber temperature, ambient temperature, suction duration, and time interval between two adjacent suction actions, as well as experimental data on heating power. These multiple sets of experimental data are then fitted to obtain a characterizing relationship between the atomizing chamber temperature and the ambient temperature, suction duration, and time interval between two adjacent suction actions. This way, after collecting the current ambient temperature, suction duration, and time interval between two adjacent suction actions, the calculated atomizing chamber temperature is more accurate, and the calculated first compensation value is also more accurate.
[0081] In some alternative embodiments, for cases where the temperature of the atomizing chamber cannot be measured by a sensor, such as Figure 5 As shown, step S120 includes:
[0082] S1203 establishes the first relationship between ambient temperature and heating parameter compensation values.
[0083] S1204 establishes a second relationship between the ambient temperature and the external ambient temperature of the electronic atomization device.
[0084] S1205, Based on the first and second relationships, construct a third relationship between the ambient temperature of the electronic atomizing device and the heating parameter compensation value. The aforementioned target relationship includes this third relationship.
[0085] The ambient temperature of the electronic atomizing device can be measured by a temperature sensor. In this embodiment, the first compensation value can be calculated directly based on the third relationship and the ambient temperature value. Accordingly, the current influence factor value in step S130 includes the current ambient temperature value.
[0086] Optionally, the second relationship is used to characterize how the ambient temperature changes with variations in external ambient temperature, suction duration, and the time interval between two adjacent suction actions. As mentioned above, this method yields a more accurate atomization chamber temperature, and consequently, a more accurate first compensation value.
[0087] The process of constructing the relationship between the cooling time of two adjacent suction actions and the corresponding second compensation value is as follows: Figure 6 As shown, it displays the temperature change curve of the next medium over time, which is plotted based on multiple experimental tests. That is, the temperature change curve of the next medium after heat transfer. Figure 6 The temperature rise segment represents the heat transfer phase during the current heating of the medium during suction; the temperature fall segment represents the cooling phase of the medium after the suction heating is completed. The medium is the heated body. By combining the experimental data on the temperature change of the medium over time with the collected experimental data on multiple sets of heating power, the relationship between the cooling time and the corresponding second compensation value can be fitted.
[0088] The process of constructing the relationship between the suction airflow velocity and the corresponding third compensation value is as follows: Figure 7 As shown, the electronic atomizing device has an inhalation port 71 through which the user can inhale. The airflow channel for inhalation is connected to a sealed space. A pressure sensor 72 is installed inside this sealed space. Figure 7 The direction of the dashed arrow in the diagram indicates the airflow direction during suction. During suction, a negative pressure with a certain difference from atmospheric pressure is formed at the location of the pressure sensor. The magnitude of this negative pressure is directly proportional to the suction airflow velocity. A fourth relationship between the pressure value at the inlet and the suction airflow velocity can be obtained by fitting multiple sets of experimental data. Figure 7 The direction of the dashed arrow indicates the direction of airflow during suction.
[0089] Furthermore, by using multiple sets of experimental data recording inlet temperature at different heating power and airflow velocities, a fifth relationship between inlet temperature and suction airflow velocity can be obtained through fitting. This fifth relationship, combined with the fourth relationship mentioned above and the heat formula Q = c·m·Δt, allows for the calculation of a sixth relationship between the third compensation value and the pressure value at the inlet. The aforementioned target relationship includes this sixth relationship. The third compensation value can then be calculated using the pressure value fed back by the pressure sensor and this sixth relationship.
[0090] In another implementation, the relationship between the third compensation value and the suction airflow velocity can also be calculated using the fifth relationship and the heat formula mentioned above. The suction airflow velocity can be calculated using the pressure value fed back by the pressure sensor and the fourth relationship mentioned above, and then the third compensation value can be calculated based on the airflow velocity.
[0091] This application provides a compensation-type power method, which determines the compensation value of heating power under different suction conditions by using the compensation relationship corresponding to three heat loss influencing factors. That is, precise temperature control is achieved through dynamic compensation of heating power, thereby ensuring the stability of the heating process and the consistency of the temperature of the heated body under different suction port numbers.
[0092] The embodiments described above establish the relationship between the power compensation value and the initial temperature of the medium, the temperature of the atomizing chamber, and the suction airflow velocity. By controlling the power output under different suction conditions (different suction times, different suction intervals, different suction velocities, and different atomizing chamber temperatures) through power compensation, different power output values are adopted as the initial temperature of the heated body and the heat dissipation conditions (including temperature changes in the area near the heated body, changes in suction velocities, and different suction intervals between the two ports) differ, thereby indirectly achieving consistency in medium temperature control or baking degree.
[0093] In one possible implementation, the aforementioned target relation, as well as the first to sixth relations, can be in the form of a relational expression.
[0094] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
[0095] It should be noted that the various method embodiments disclosed in this application can be freely combined, and the technical solutions obtained after free combination are also within the protection scope of this application.
[0096] Another embodiment of this application discloses an electronic atomizing device. For example... Figure 8 As shown, the electronic atomizing device, in addition to including a heating module 81, a passive component 11, and an active component 12, also includes a control module 84. The heating module 81 and the control module 84 are connected, and the control module 84 controls the heating module 81. The active component 12 drives the passive component 11 to rotate via a heated body 13. This control module implements the control method disclosed in any of the above embodiments. Exemplarily, the control module can be an MCU (Microcontroller Unit). It should be noted that... Figure 8 The number of passive components shown is two, and the number of active components is one, but this application is not limited thereto.
[0097] In one optional embodiment, the heating module includes a heating element and a resonant unit. The heating element and the heated body are correspondingly arranged for heating the heated body. The heating element and the heated body are disposed within a target space. The resonant unit is disposed opposite to the heating element and is used to generate a magnetic field in the target space to heat the heating element. The heating element can be in contact with the heated body, thereby achieving heat conduction. The resonant unit is an L (inductor) C (capacitor) resonant unit.
[0098] Optionally, such as Figure 9As shown, the heating module includes a heating element 91, a resonant unit 92, a sampling unit 93, and a driving unit 94. The aforementioned control module is connected to the sampling unit and the driving unit, respectively. The sampling unit is used to sample the electrical parameters in the heating module. The sampling unit samples at least one parameter among voltage, current, and power in the circuit. The driving unit converts the power supply into a driving signal, driving the LC resonant unit to resonate and generate a magnetic field. The alternating magnetic field generated by the resonant unit spreads outwards. The heating element, being a metal structure, generates eddy currents due to the cutting of magnetic field lines, thus generating self-heat and heating the object being heated. For example, the heating element can be one of aluminum foil, tin foil, or stainless steel sheet.
[0099] Optionally, the aforementioned electronic atomization device may further include a heated body movement distance detection module. This module detects the movement distance of the heated body, primarily used to determine its movement distance when the heated body is moved after the main heating stage. The heated body movement distance detection module can be located on one side of the heated body's movement trajectory. The detection methods for this module include, but are not limited to, motion image recognition detection, infrared reflection detection of marking lines, and infrared transmission (medium perforation) detection.
[0100] In some alternative embodiments, the electronic atomizing device also includes a motor. The motor is connected to the active component and drives the active component to rotate. For example, the motor provides the active component with the power to retract by engaging with it, causing the heated element to move and retract in a fixed direction.
[0101] Optionally, after the electronic atomizing device is turned on, the heated body can be tightened to keep it in a straight state.
[0102] Optionally, after the heating process triggered by the inhalation action ends, the electronic atomizing device can either cease heating and enter standby or power-off mode, or it can enter a heat preservation mode with lower power to facilitate rapid aerosol generation and provide a suitable temperature for the next inhalation. If there is no inhalation for an extended period (e.g., 600 seconds), the heat preservation mode will be exited, and the device will automatically power off.
[0103] The electronic atomizing device provided in this application adopts a compensated heating power control method under power control heating mode. Based on the target relationship that can characterize the relationship between the heat loss influencing factor and the heating parameter compensation value, the current parameter compensation value is determined according to the current influencing factor value. The heating module is controlled to heat by using the adjusted heating parameter value that is more accurate under the current heating conditions. This realizes the adjustment of heating parameter output considering the influence of different conditions and factors, so as to ensure the consistency of medium heating under different suction conditions, improve the consistency of medium temperature control, and thus achieve better heating effect and product quality.
[0104] In any of the above embodiments of this application, the specific type of electronic atomizing device is not limited. For example, electronic atomizing devices include, but are not limited to, air humidifiers, medical atomizers, or electronic cigarettes.
[0105] The aerosol-generating matrix can be solid or gel-like.
[0106] The specific details regarding the solid aerosol generation matrix are as follows:
[0107] The aerosol-generating matrix may include plant components, adjuvant components, smoke-generating agent components, and binder components. Plant components can be one or more combinations of powders formed from crushed tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants. These plant components are used to generate aerosols containing alkaloids when heated.
[0108] In one embodiment, the aerosol generating matrix is a one-piece molded structure. For example, the aerosol generating matrix can be a one-piece structure formed through processes such as injection molding, compression molding, or extrusion. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the mixture is pushed forward by the screw through the extruder barrel and screw, continuously passing through the die head to form products or semi-finished products of various cross-sections. The aerosol generating matrix formed by extrusion molding is strip-shaped. Thus, the aerosol generating matrix remains a one-piece medium after being heated and absorbed or after heating ceases, making it less prone to disintegration and falling off.
[0109] In one embodiment, the aerosol generating matrix can be generally columnar in structure. That is, the aerosol generating matrix is generally elongated, and the longitudinal length of the aerosol generating matrix is greater than the distance between any two points on its cross-section.
[0110] In a cross-section perpendicular to the longitudinal direction of the aerosol-generating matrix, the cross-sectional shape of the aerosol-generating matrix includes, but is not limited to, circular, elliptical, racetrack-shaped, or polygonal shapes. Taking a circular cross-sectional shape as an example, the aerosol-generating matrix is roughly cylindrical, and the longitudinal direction of the aerosol-generating matrix is the axis of the cylinder.
[0111] In one embodiment, the heating element is located on the outer periphery of the aerosol generating matrix, which is divided into multiple regions along the circumference, with each region corresponding to a heating element. This allows for selective heating of different regions along the circumference of the aerosol generating matrix by different heating elements, enabling the release of aerosols from different parts of the matrix. This results in fresher aerosols and a richer flavor for each inhalation.
[0112] In one embodiment, a cavity is formed inside the aerosol generating matrix, and a heating element is located in the cavity. The aerosol generating matrix is divided into multiple regions along the circumference, with each region corresponding to a heating element. This allows for selective heating of different regions of the aerosol generating matrix using different heating elements.
[0113] In one embodiment, the aerosol generating matrix may have multiple media segments along its length, with each media segment corresponding to a heating element. This allows for the selective heating of different media segments of the aerosol generating matrix by using different heating elements.
[0114] In one embodiment, each electronic atomizing device contains multiple aerosol generating substrates. That is, there can be multiple aerosol generating substrates, with each substrate corresponding to a heating element. This allows different aerosol generating substrates to be selectively heated by different heating elements.
[0115] In some embodiments, when there are multiple heating elements, each heating element can be controlled independently. Independent control of each heating element means that each heating element can be individually controlled to turn on, off, or have its temperature adjusted. For example, if each heating element is powered independently, then independent control of each heating element can be achieved.
[0116] In some embodiments, the heating element can be a resistive heating structure. The heating element can be a heating wire, a heating mesh, or a heating plate.
[0117] In some embodiments, the electronic atomizing device includes a power supply unit for powering electrically powered components such as a heating module. The power supply unit includes, but is not limited to, devices capable of providing electrical energy, such as batteries. The power source includes, but is not limited to, batteries. The battery can be a disposable battery or a rechargeable battery.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
