Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to a method and system for detecting whether a heating element of an electronic atomization device is qualified. Background Art

[0002] During the production process of existing electronic atomization devices, the heating elements need to be tested to ensure that the electronic atomization devices have good performance when they are in the hands of users. The current testing of heating elements is through calibrating their power. Specifically, each heating element is heated with different powers at different time stages during the heating process. The general heating time of this method is 150s. Due to the long calibration time, low output power, and slow temperature rise, the temperature of the subsequent heating elements will be in a stable state. At the end of the calibration, the TCR value of some areas where heat is concentrated is not much different from that of normal heating elements, making it impossible to determine whether the heating element is qualified.

[0042] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0043] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0044] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0045] like Figure 1 As shown, this embodiment provides a method for detecting whether a heating element of an electronic atomization device is qualified, including the following steps:

[0046] Step 100: The heating module controls the heating element to heat at a preset power for a preset time;

[0047] Step 200: The acquisition module acquires the resistance value of the heating element at a preset time interval;

[0048] Step 300: The curve establishing module establishes a time-resistance curve of the current heating element according to the acquired resistance value;

[0049] Step 400: The judgment module compares the time-resistance curve with the standard curve. When the time-resistance curve is consistent with the standard curve, the current heating element is determined to be qualified, otherwise it is unqualified. Among them, the judgment standard for whether the time-resistance curve is consistent with the standard curve is: the deviation ratio between the time-resistance curve and the standard curve is within 10%.

[0050] Specifically, before the test, the heating tube with uniform heating in the oil bath test will be preheated as a standard resistance tube, and the resistance value of each point (a total of 3 seconds, one point is collected every 0.1 seconds) will be recorded to form a standard curve in each test heating channel. During the test, the heating element is quickly heated up by the preset heating power, and the heating time does not exceed 3 seconds. When the heating time exceeds 3 seconds, the temperature of the heating element will be output at a constant temperature. Taking the heating time of 3 seconds and the preset time interval of 0.1 seconds as an example, the heating element is controlled to read the resistance of the heating element every 0.1 seconds during the heating process at the preset power. For the heating element with concentrated heat, the concentrated heat area will heat up faster than the normal heat area during the initial power-on process. The heating element with concentrated heat for a short time and high power will reach a higher temperature and a larger resistance under the same conditions, which will cause the resistance to deviate from the standard curve, so as to screen whether the heating element is qualified. Therefore, this embodiment establishes a time-resistance curve of the current heating element based on the multiple resistance values obtained, such as Figure 3 As shown, the time-resistance curve is compared with the standard curve to determine whether the heating element is qualified. When the time-resistance curve of the current heating element is consistent with the standard curve (that is, the deviation ratio between the time-resistance curve and the standard curve is within 10%), the current heating element is determined to be qualified; otherwise, the current heating element is determined to be unqualified. The solution of this embodiment avoids the measurement / calculation of multiple parameters in the electronic atomization device, not only reducing intermediate errors, but also enabling the rapid, efficient and accurate screening of qualified heating elements.

[0051] Furthermore, the heating element includes an upper heating element and a lower heating element, and the upper heating element and the lower heating element are connected in parallel; controlling the heating element to heat at a preset power for a preset time includes:

[0052] Controlling the upper heating element to heat at a preset power for a preset time, while controlling the output power of the lower heating element to zero so that the lower heating element does not generate heat;

[0053] After the upper heating element is heated at a preset power for a preset time, the upper heating element is cooled for a preset time;

[0054] Then the lower heating element is controlled to heat at a preset power for a preset time, and at the same time, the output power of the upper heating element is controlled to be zero, so that the upper heating element does not generate heat.

[0055] In practical applications, the heating element can be set as an upper heating element and a lower heating element, wherein the upper heating element and the lower heating element are connected in parallel. Figure 2First, the upper heating element is powered by a 4.7V power supply. At the same time, the PWM duty cycle of the lower heating element is adjusted to make the output power of the lower heating element zero, so that the lower heating element does not generate heat. At this time, within the preset heating time, the resistance of the upper heating element is obtained and recorded at preset time intervals. Based on the obtained resistance, a time-resistance curve (i.e., a first time-resistance curve) of the upper heating element is established. After the upper heating element is heated, the heating element (specifically, the upper heating element) is allowed to cool for a certain period of time, and the cooling fan can be turned on for 40 seconds.

[0056] Then, the lower heating element is powered by a 4.7V power supply. At the same time, the PWM duty cycle of the upper heating element is adjusted to make the output power of the upper heating element zero, so that the upper heating element does not generate heat. At this time, within the preset heating time, the resistance of the lower heating element is obtained and recorded at preset time intervals, and the time-resistance curve of the lower heating element (i.e., the second time-resistance curve) is established based on the obtained resistance.

[0057] Among them, it should be noted that, for the standard curve, the heating tube with uniform heating in the oil bath test is used as the standard resistance tube, the upper and lower sections are heated respectively at the same preset time, and the resistance values of the upper and lower sections are collected at preset time intervals to form a standard curve for each test channel, that is, the upper heating element standard curve (first standard curve) and the lower heating element standard curve (second standard curve).

[0058] Compare the time-resistance curve of the upper heating element with the standard curve of the upper heating element, and compare the time-resistance curve of the lower heating element with the standard curve of the lower heating element. Only when the time-resistance curve of the upper heating element is consistent with the standard curve of the upper heating element, and the time-resistance curve of the lower heating element is consistent with the standard curve of the lower heating element, can the current heating element be determined to be qualified; otherwise, it is unqualified.

[0059] In some embodiments, obtaining the resistance of the heating element at a preset time interval specifically includes:

[0060] When the output power of the lower heating element is zero, the resistance value of the upper heating element is obtained at a preset time interval. The calculation principle of the resistance value of the upper heating element is:

[0061]

[0062] Where R 上 is the resistance of the upper heating element; R 参 Indicates the reference resistance, which is 5.1Ω; V 满 Indicates the full-charge voltage of the heating element, which is represented by 4096 (full-charge voltage code) in the control system; V ADCIndicates the heating element voltage corresponding to the measurement time point (0 to 4096 during acquisition).

[0063] When the output power of the upper heating element is zero, the resistance value of the lower heating element is obtained at a preset time interval. The calculation principle of the resistance value of the upper heating element is:

[0064]

[0065] Where R 下 is the resistance of the lower heating element; R 参 Indicates the reference resistance, which is 5.1Ω; V 满 Indicates the full-charge voltage of the heating element, which is represented by 4096 (full-charge voltage code) in the control system; V ADC Indicates the heating element voltage corresponding to the measurement time point (0 to 4096 during acquisition).

[0066] refer to Figure 4 This embodiment provides a system for detecting the conformity of a heating element in an electronic atomization device, comprising a heating module, an acquisition module, a curve creation module, and a judgment module. The heating module controls the heating element to heat at a preset power for a preset time; the acquisition module acquires the resistance of the heating element at preset time intervals; the curve creation module creates a time-resistance curve for the current heating element based on the acquired resistance; and the judgment module compares the time-resistance curve with a standard curve. If the time-resistance curve matches the standard curve, the current heating element is determined to be conformity; otherwise, it is determined to be conformity.

[0067] The present embodiment provides a system for detecting whether a heating element of an electronic atomization device is qualified. The heating element is controlled by a heating module 10 to heat at a preset power for a preset time. During the preset time, the acquisition module 20 acquires the resistance of the heating element at preset time intervals. Then, the curve establishment module 30 establishes a time-resistance curve of the heating element based on the acquired resistance. Finally, the judgment module 40 compares the time-resistance curve with a standard curve to determine whether the current heating element is qualified. Using the system of the present application, it is possible to directly determine whether the heating element is qualified by measuring its resistance, avoiding multi-parameter measurement / calculation, not only reducing intermediate errors, but also enabling the rapid, efficient and accurate screening of qualified heating elements.

[0068] Since the functions that can be achieved by the heating module 10, the acquisition module 20, the curve establishment module 30 and the judgment module 40 and the technical effects brought about have been described in detail in the above-mentioned embodiment of the method for detecting whether the heating element of the electronic atomization device is qualified, this embodiment will not be repeated in detail here.

[0069] Furthermore, the heating element includes an upper heating element and a lower heating element, and the upper heating element and the lower heating element are connected in parallel; the heating module 10 includes a first heating unit, a cooling unit and a second heating unit: the first heating unit is used to control the upper heating element to heat for a preset time with a preset power, and at the same time, control the output power of the lower heating element to be zero, so that the lower heating element does not generate heat; the cooling unit is used to cool the upper heating element for a preset time after the upper heating element is heated for a preset time with a preset power; the second heating unit is used to subsequently control the lower heating element to heat for a preset time with a preset power, and at the same time, control the output power of the upper heating element to be zero, so that the upper heating element does not generate heat.

[0070] In practical applications, the heating element can be set as an upper heating element and a lower heating element, wherein the upper heating element and the lower heating element are connected in parallel. Figure 2 First, the first heating unit supplies power to the upper heating element through a 4.7V power supply. At the same time, the PWM duty cycle of the lower heating element is adjusted to make the output power of the lower heating element zero, so that the lower heating element does not generate heat. At this time, within the preset heating time, the resistance of the upper heating element is obtained and recorded at preset time intervals, and a time-resistance curve of the upper heating element (i.e., a first time-resistance curve) is established based on the obtained resistance. After the heating of the upper heating element is completed, the cooling unit cools the heating element (specifically, the upper heating element) for a certain period of time. The cooling unit can specifically use a cooling fan, which is turned on for 40 seconds.

[0071] Then, the second heating unit supplies power to the lower heating element through a 4.7V power supply. At the same time, the PWM duty cycle of the upper heating element is adjusted to make the output power of the upper heating element zero, so that the upper heating element does not generate heat. At this time, within the preset heating time, the resistance of the lower heating element is obtained and recorded at preset time intervals, and the time-resistance curve of the lower heating element (i.e., the second time-resistance curve) is established based on the obtained resistance.

[0072] Among them, it should be noted that, for the standard curve, the heating tube with uniform heating in the oil bath test is used as the standard resistance tube, the upper and lower sections are heated respectively at the same preset time, and the resistance values of the upper and lower sections are collected at preset time intervals to form a standard curve for each test channel, that is, the upper heating element standard curve (first standard curve) and the lower heating element standard curve (second standard curve).

[0073] Compare the time-resistance curve of the upper heating element with the standard curve of the upper heating element, and compare the time-resistance curve of the lower heating element with the standard curve of the lower heating element. Only when the time-resistance curve of the upper heating element is consistent with the standard curve of the upper heating element, and the time-resistance curve of the lower heating element is consistent with the standard curve of the lower heating element, can the current heating element be determined to be qualified; otherwise, it is unqualified.
