[0045] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, 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 part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0046] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0047] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0048] Before explaining in detail the atomization device and the temperature control method of the atomization device provided in the present application, the application scenarios involved in the embodiments of the present application are first introduced.

[0049] The current atomizer equipment uses a PID controller to achieve precise temperature control, that is, the PID controller is used to change the heating power of the atomizer equipment so that the actual temperature of the atomizer equipment is stabilized at the target temperature. However, during the heating operation of the atomizer equipment, the values ​​of various parameters such as P (proportional coefficient), I (integral time), and D (differential time) cannot be changed, and the temperature difference critical value is pre-set and cannot be changed. Therefore, the heating rate or cooling rate of the atomizer equipment during use cannot be changed, thereby reducing the heating rate or cooling rate of the atomizer equipment. Moreover, when the atomizer equipment needs to change the temperature significantly in a short period of time, the temperature of the atomizer equipment may be unstable, which seriously affects the user experience.

[0050] Based on this, an embodiment of the present application provides an atomization device, which can predict in advance the difference between the actual temperature of the heating element in the atomization device and the target temperature, and dynamically determine the corresponding critical temperature difference value based on this, so as to reduce the difference between the actual temperature of the heating element and the target temperature; in addition, it can also flexibly determine whether the temperature control unit is needed to calculate the duty cycle, thereby enabling the atomization device to quickly heat up when it needs to heat up, and quickly cool down when it needs to cool down.

[0051] Next, the atomization equipment provided in the embodiment of the present application is introduced in detail.

[0052] Please refer to Figure 1 , Figure 1It is a structural schematic diagram of an atomization device provided in an embodiment of the present application. The atomization device includes: a heating unit 1, the heating unit 1 includes at least one heating element 11, when multiple heating elements 11 are included, each heating element 11 is driven independently; the heating element 11 is used to generate heat so that the atomization device works. A storage unit 2, the storage unit 2 is used to store one or more target temperature curves, each of the at least one heating element 11 has a corresponding target temperature curve, and the target temperature curve is used to indicate the relationship between the heating time and the temperature of the corresponding heating element 11. A temperature control unit 3, the temperature control unit 3 is used to calculate the duty cycle to control the heating power of the heating element 11 based on the duty cycle. The logic unit 4 is used to call the temperature control unit 3 at a certain frequency, and determine whether the temperature control unit 3 needs to calculate the duty cycle when calling the temperature control unit 3. The specific process is: determine the target temperature of the corresponding heating element 11 at the current time point according to the target temperature curve, and obtain the actual temperature of the corresponding heating element 11 at the current time point; based on the target temperature at the current time point, the actual temperature at the current time point, and the first critical temperature difference value, determine whether the temperature control unit 3 needs to calculate the duty cycle; wherein the first critical temperature difference value is the critical temperature difference value corresponding to the current time point, and the first critical temperature difference value is determined at the previous time point based on the predicted temperature at the current time point and the target temperature at the current time point; the predicted temperature at the current time point is the temperature at the current time point obtained from the previous time point when the temperature control unit 3 controls the corresponding heating element 11 to generate heat with the heating power at the previous time point, and the previous time point and the current time point are separated by a preset time period.

[0053] That is, the number of target temperature curves stored in the storage unit 2 corresponds to the at least one heating element 11 included in the heating unit 1, that is, each of the at least one heating element 11 has a corresponding target temperature curve. For example, if the heating unit includes two heating elements, namely, heating element X and heating element Y, and heating element X has a target temperature curve X, and heating element Y has a target temperature curve Y, then two target temperature curves, namely, target temperature curve X and target temperature curve Y, are stored in the storage unit 2.

[0054] And in the case where the heating unit 1 includes multiple heating elements 11, each of the multiple heating elements 11 is driven independently, that is, whether each heating element 11 performs heating work and the temperature to be reached may be the same or different, so it can be seen that the target temperature curves corresponding to the multiple heating elements 11 may be the same or different. As an example, the heating unit 1 is divided into an upper section and a lower section, that is, it has two heating elements 11, and the upper section and the lower section have different corresponding temperatures at different heating time points, so it can be seen that the target temperature curve of the upper section is different from the target temperature curve corresponding to the lower section.

[0055] In some embodiments, at least one target temperature curve in the storage unit 2 is pre-set in the storage unit 2 by a technician before the atomization device leaves the factory, so that in subsequent processes, relevant operations can be performed directly according to the stored target temperature curve.

[0056] It should be noted that the above description is based on the assumption that the at least one temperature curve is pre-set by a technician, or, in application, the target temperature curve may also be determined by other methods, which is not limited in the embodiments of the present application.

[0057] In addition, in some embodiments, the temperature control unit 3 may be a PID controller. The PID controller is composed of a proportional unit (P), an integral unit (I) and a differential unit (D), which can calculate the duty cycle and control the heating power of the heating element 11 based on the calculated duty cycle, so that the heating element 11 can achieve the effect of heating, cooling or stabilizing the temperature.

[0058] It should be noted that the above description is based on the temperature control unit 3 being a PID controller, or, in application, the temperature control unit 3 may also be other devices capable of controlling temperature, which is not limited in the embodiments of the present application.

[0059] The logic unit 4 can call the temperature control unit 3 at a certain frequency, for example, the logic unit 4 calls the temperature control unit 3 once every 100 milliseconds. And each time the temperature control unit 3 is called, it is determined whether the temperature control unit 3 needs to calculate the duty cycle, so as to quickly heat up or cool down the heating element 11.

[0060] Based on the above description, it can be known that the target temperature curve is used to indicate the relationship between the time and temperature of the corresponding heating element 11. Therefore, the logic unit can determine the target temperature of the corresponding heating element 11 at the current time point according to the target temperature curve. For example, the heating element 11 has been heated for a total of 25 seconds from the beginning of heating to the present, that is, the current time point is 25 seconds. Therefore, the logic unit 4 can search the target temperature corresponding to the heating time of 25 seconds in the target temperature curve.

[0061] It should be noted that the heating time may be timed by a timer included in the atomization device, or by the logic unit 4, which is not limited in the embodiment of the present application.

[0062] Continuing with the above description, the logic unit 4 can also obtain the actual temperature of the corresponding heating element 11 at the current time point, so that in the subsequent process, according to the target temperature at the current time point, the actual temperature at the current time point and the first critical temperature difference value, it is determined whether the temperature control unit 2 needs to calculate the duty cycle for the temperature control unit 3 this time.

[0063] Among them, the first critical temperature difference value is determined at the previous time point based on the predicted temperature at the current time point and the target temperature at the current time point, and the predicted temperature at the current time point is the temperature at the current time point obtained when the temperature control unit 3 controls the corresponding heating element 11 to generate heat with the heating power at the previous time point from the previous time point to the current time point. It can be seen that the actual temperature at the current time point can be predicted in advance at the previous time point based on the actual temperature and heating power at the previous time point, and the first critical temperature difference value corresponding to the current time point is determined at the previous time point based on the predicted temperature at the current time point (i.e., the predicted temperature at the current time point) and the target temperature at the current time point, so that when the heating time of the corresponding heating element 11 is from the previous time point to the current time point, the actual temperature at the current time point can be close to the target temperature at the current time point.

[0064] Moreover, the previous time point and the current time point are separated by a preset time period. For example, assuming that the preset time period is 3 seconds, the previous time point can be (t-3) seconds, and the current time point can be t seconds. For example, the previous time point is 22 seconds, and the current time point is 25 seconds.

[0065] Continuing with the above example, assuming that the heating time is (t-3) seconds, and the heating power at (t-3) seconds is V, and the temperature of the heating element is A, the logic unit 4 can predict the actual temperature of the heating element at t seconds based on the heating power V and the temperature A at (t-3) seconds, and then obtain the target temperature of the heating element at t seconds according to the target temperature curve, so as to determine the critical temperature difference corresponding to t seconds based on the predicted actual temperature and target temperature at t seconds, so as to ensure that during the heating process of the heating element, when the heating time point is t seconds, the actual temperature of the heating element can be close to the target temperature, thereby improving the user experience of the atomization device.

[0066] In some embodiments, the logic unit 4 can also calculate the difference between the target temperature at the current time point and the actual temperature at the current time point; if the difference between the target temperature at the current time point and the actual temperature at the current time point is greater than the first critical temperature difference, it is determined that the temperature control module 3 does not need to calculate the duty cycle, and the temperature control unit 3 controls the corresponding heating element 11 to output full power for heating, so that the corresponding heating element 11 can heat up quickly.

[0067] After obtaining the target temperature at the current time point and the actual temperature at the current time point, the logic unit 4 can also determine the difference between the target temperature and the actual temperature, and determine whether the temperature control module 3 needs to calculate the duty cycle based on the determined difference and the first critical temperature difference.

[0068] That is to say, if the difference between the target temperature at the current time point and the actual temperature at the current time point is greater than the first critical temperature difference, it means that the actual temperature at the current time point is far from the target temperature at the current time point, and the corresponding heating element 11 needs to be heated at full power so that the actual temperature of the heating element 11 can be quickly raised to the target temperature in the subsequent process. In the above case, the temperature control module 3 does not need to calculate the duty cycle, but only needs to control the corresponding heating element 11 to output heating at full power, so that the corresponding heating element 11 can quickly heat up.

[0069] In addition, in some embodiments, if the difference between the target temperature at the current time point and the actual temperature at the current time point is not greater than the critical temperature difference value, the logic unit 4 can also determine whether the difference between the target temperature at the current time point and the actual temperature at the current time point is less than the inverse of the first critical temperature difference value; if the difference between the target temperature at the current time point and the actual temperature at the current time point is less than the inverse of the first critical temperature difference value, it is determined that the temperature control module 3 does not need to calculate the duty cycle, and the temperature control unit 3 controls the corresponding heating element 11 not to generate heat, so that the corresponding heating element 11 can be cooled down quickly; if the difference between the target temperature at the current time point and the actual temperature at the current time point is greater than or equal to the inverse of the first critical temperature difference value, and is less than or equal to the first critical temperature difference value, it is determined that the temperature control module 3 needs to calculate the duty cycle, and the temperature control module 3 controls the heating power of the corresponding heating element 11 based on the calculated duty cycle.

[0070] That is to say, if the difference between the target temperature at the current time point and the actual temperature at the current time point is not greater than the critical temperature difference value, the logic unit 4 also needs to determine whether the temperature difference between the target temperature at the current time point and the actual temperature at the current time point is less than the inverse of the first critical temperature difference value, so as to determine whether the actual temperature at the current time point exceeds the target temperature at the current time point by too much, so as to determine whether the corresponding heating element 11 needs to be cooled down quickly.

[0071] If the difference between the target temperature at the current time point and the actual temperature at the current time point is less than the inverse of the first critical temperature difference value, it means that the actual temperature at the current time point exceeds the target temperature at the current time point by too much, and the corresponding heating element needs to be stopped from generating heat, that is, zero power output, so that the actual temperature of the heating element 11 can be quickly reduced to the target temperature in the subsequent process. In the above case, the temperature control module 3 does not need to calculate the duty cycle, but only needs to control the corresponding heating element 11 to stop generating heat, so that the corresponding heating element 11 can be quickly cooled down.

[0072] If the difference between the target temperature at the current time point and the actual temperature at the current time point is greater than or equal to the inverse of the first critical temperature difference value, and is less than or equal to the first critical temperature difference value, that is, the difference between the actual temperature at the current time point and the target temperature at the current time point is not less than the inverse of the first critical temperature difference value, and is not greater than the first critical temperature difference value, it means that the current temperature control unit 3 can intervene in the calculation, so that the actual temperature of the heating element 11 is stabilized at the target temperature. That is to say, in the above case, the logic unit 4 determines that the temperature control module 3 needs to calculate the duty cycle, and after the temperature control module 3 calculates the duty cycle, the corresponding heating power of the heating element 11 is controlled based on the duty cycle, so as to stabilize the actual temperature of the heating element 11.

[0073] In some embodiments, the logic unit 4 can also determine the target temperature at the next time point based on the target temperature curve, and the current time point is separated from the next time point by a preset time period; determine the predicted temperature at the next time point based on the actual temperature at the current time point and the heating power corresponding to the current time point; and determine the second critical temperature difference value corresponding to the next time point based on the target temperature at the next time point and the predicted temperature at the next time point; when the difference between the target temperature at the next time point and the actual temperature at the next time point is greater than or equal to the inverse of the second critical temperature difference value, and is less than or equal to the second critical temperature difference value, the temperature control unit 3 is controlled to calculate the duty cycle to stabilize the temperature of the heating element 11.

[0074] That is to say, the logic unit 4 can also predict the actual temperature at the next time point based on the actual temperature and heating power at the current time point. That is, starting from the current time point, the temperature control unit controls the corresponding heating element to generate heat based on the actual temperature at the current time point and the heating power corresponding to the current time point, and when it reaches the next time point, the predicted temperature at the next time point is determined.

[0075] Then, the current time point determines the second critical temperature difference value corresponding to the next time point based on the predicted temperature at the next time point and the target temperature at the next time point, so that when the heating time of the corresponding heating element 11 is from the current time point to the next time point, the actual temperature at the next time point can be close to the target temperature at the next time point.

[0076] Moreover, the current time point and the next time point are separated by a preset time period. For example, assuming that the preset time period is 3 seconds, the current time point may be t seconds, and the next time point may be (t+3) seconds. For example, the current time point is 25 seconds, and the next time point is 28 seconds.

[0077] Continuing with the above example, assuming that the heating time is t seconds, and the heating power at t seconds is U, and the temperature of the heating element is B, the logic unit 4 can predict the actual temperature of the heating element at (t+3) seconds based on the heating power U and the temperature B at t seconds, and obtain the target temperature of the heating element at (t+3) seconds according to the target temperature curve, so as to determine the critical temperature difference corresponding to (t+3) seconds based on the actual temperature and target temperature predicted at (t+3) seconds, so as to ensure that during the heating process of the heating element, when the heating time point is (t+3) seconds, the actual temperature of the heating element can be close to the target temperature, thereby improving the user experience of the atomization device.

[0078] Continuing with the above description, at the next time point, the logic unit 3 can also determine that the temperature control unit 3 needs to calculate the duty cycle when the difference between the target temperature at the next time point and the actual temperature at the next time point is greater than or equal to the inverse of the second critical temperature difference value, and less than or equal to the second critical temperature difference value. In other words, the temperature control unit 3 can intervene in the calculation, that is, the temperature control unit 3 needs to calculate the duty cycle, and after calculating the duty cycle, control the heating power of the corresponding heating element 11 based on the duty cycle, so that the actual temperature of the heating element 11 is stabilized at the target temperature.

[0079] In some embodiments, when the logic unit 4 determines that the temperature control unit 3 needs to calculate the duty cycle, the temperature control unit 3 can also determine the target duty cycle by multiplying the first duty cycle by the ratio of the second critical temperature difference value to the first critical temperature difference value when the corresponding heating element 11 is in a heating state, wherein the first duty cycle is the duty cycle corresponding to the heating power of the corresponding heating element 11 currently controlled by the temperature control unit 3 to generate heat; when the heating element 11 is not in a heating state, the target duty cycle is determined by multiplying the first duty cycle by the ratio of the first critical temperature difference value to the second critical temperature difference value; and the heating power of the corresponding heating element 11 is controlled based on the target duty cycle.

[0080] For example, when the corresponding heating element 11 is in a temperature rising state, the target duty cycle can be determined according to the following formula (1):

[0081]

[0082] Wherein, A1 represents the target duty cycle, A0 represents the first duty cycle, T1 represents the first temperature difference critical value, and T2 represents the second critical temperature difference value.

[0083] As another example, when the corresponding heating element 11 is in a cooling state, the target duty cycle can be determined according to the following formula (2):

[0084]

[0085] It should be noted that the above-mentioned method for determining the target duty cycle is for illustration only. In application, the target duty cycle may also be determined by other methods, which is not limited in the embodiments of the present application.

[0086] In some embodiments, the logic unit 4 can determine whether the corresponding heating element 11 is in a heating state or a cooling state based on the size relationship between the target temperature at the current time point and the target temperature at the previous time point, and send the determined state to the temperature control unit 3, so that the temperature control unit 3 obtains the current state of the heating element 11 and determines the target duty cycle based on the state. Alternatively, the temperature control unit 3 can determine whether the corresponding heating element 11 is in a heating state or a cooling state based on the size relationship of the duty cycle calculated each time. This embodiment of the application is not limited to this.

[0087] In some embodiments, the storage unit 2 is also used to store a relative change relationship, which is used to indicate the relative change of the temperature of the heating element 11 and its resistance when it changes by one degree Celsius; the logic unit 4 is also used to determine the actual temperature of the corresponding heating element 11 at the current time point based on the resistance of the corresponding heating element 11 at the current time point, the initial resistance of the corresponding heating element 11, the relative change relationship and the current ambient temperature.

[0088] In addition, in some embodiments, the relative change relationship is TCR. TCR represents the relative change of the resistance of the heating element 11 when the temperature of the heating element 11 changes by 1°C, and its unit is ppm / °C.

[0089] As an example, the actual temperature at the current time point may be determined according to the following formula (3):

[0090]

[0091] Wherein, T represents the actual temperature at the current time point, R1 represents the resistance value of the corresponding heating element 11 at the current time point, R0 represents the initial resistance value of the corresponding heating element 11, TCR represents the relative change relationship, T S Indicates the ambient temperature at the current time.

[0092] It should be noted that the above is explained by determining the actual temperature of the corresponding heating element 11 at the current time point based on the resistance value of the corresponding heating element 11 at the current time point, the initial resistance value of the corresponding heating element 11, the relative change relationship and the current ambient temperature. Alternatively, in application, the actual temperature of the corresponding heating element 11 at the current time point can also be directly measured by a temperature sensor or other methods can be used to obtain the actual temperature of the corresponding heating element 11 at the current time point.

[0093] In addition, in some embodiments, the logic unit 4 can also obtain the resistance value of the corresponding heating element 11 at the current time point by collecting the ADC (Analog to Digital Converter) value and performing calculations based on the ADC value, or the logic unit 4 can also determine the resistance value at the current time point by other means; the initial resistance value can be set by a technician, so that the logic unit 4 can directly obtain the initial resistance value when needed; the ambient temperature at the current time point can be measured by the temperature sensor included in the atomization device, or it can be determined by other means. The embodiments of the present application are not limited to this.

Moreover, when the difference between the target temperature and the actual temperature at the current time point is greater than the first critical temperature difference, the logic unit determines that the temperature control unit does not need to calculate the duty cycle, and makes the temperature control unit control the corresponding heating element to output at full power, so that the temperature can be quickly heated up when the atomization device needs to be heated up; when the difference between the target temperature and the actual temperature at the current time point is less than the opposite number of the first critical temperature difference, it is determined that the temperature control module does not need to calculate the duty cycle, and makes the temperature control unit control the corresponding heating element not to generate heat, so that the temperature can be quickly cooled down when the atomization device needs to be cooled down.
