TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generating device, in particular to an aging test method and device of a heating assembly, and a computer storage medium. BACKGROUND

[0002] Currently, the aging of an HBN (heating but not burning) aerosol generating device generally requires about 8000 cycles of temperature curve, wherein the temperature curve of the HBN aerosol generating device refers to a process curve of how the heating element inside the aerosol generating device is heated, maintained and cooled over time during the aging test or normal use. Although the use of the temperature curve cycle can accurately evaluate the service life and stability of the heating element, the entire aging test requires 3 to 4 months, and such a long period results in that the test results cannot be fed back in time, delaying the discovery and solution of problems, which is not conducive to the rapid iteration and improvement of products. Moreover, a large amount of temperature data and other performance index data are generated during the long-term aging test, which is large in data volume and difficult to process, increasing the complexity and workload of result analysis. SUMMARY

[0009] The timing module is configured to obtain a first set time length during which the power module outputs the set value of the electrical parameter to the heating assembly, and a second set time length during which the power module stops outputting the set value of the electrical parameter to the heating assembly.

[0010] When the time length during which the power module outputs the set value of the electrical parameter to the heating assembly reaches the first set time length, the control module controls the power module to stop outputting the set value of the electrical parameter to the heating assembly; and when the time length during which the power module stops outputting the set value of the electrical parameter to the heating assembly reaches the second set time length, the control module completes one cycle.

[0011] In an embodiment, the aging test device further comprises a heat dissipation module.

[0012] The heat dissipation module is configured to dissipate heat from the heating assembly when the power module stops outputting the set value of the electrical parameter to the heating assembly.

[0013] In an embodiment, the control module determines whether the aging test of the heating assembly passes according to the initial resistance value and the current resistance value, comprising:

[0014] The control module calculates a ratio of the current resistance value to the initial resistance value, and when the ratio is within a set ratio range, the aging test of the heating assembly passes.

[0015] In an embodiment, the set value is greater than or equal to a maximum value of the electrical parameter reached when the heating assembly is in operation.

[0016] According to a second aspect, in an embodiment, there is provided an aging test method of a heating assembly applied to an aerosol generating device, comprising:

[0017] Obtaining an initial resistance value of the heating assembly when no set value of an electrical parameter is output to the heating assembly to be tested;

[0018] Cycling output or stop of the set value of the electrical parameter to the heating assembly, and obtaining a cycle number;

[0019] When the cycle number reaches a set number, obtaining a current resistance value of the heating assembly when the cycle is completed;

[0020] Determining whether the aging test of the heating assembly passes according to the initial resistance value and the current resistance value.

[0021] In an embodiment, the aging test method further comprises:

[0022] When the time length during which the set value of the electrical parameter is output to the heating assembly reaches a first set time length, the set value of the electrical parameter is stopped being output to the heating assembly.

[0023] When the duration that the output of the electric parameter of the set value to the heating assembly is stopped reaches a second set duration, one cycle is completed.

[0024] In one embodiment, determining whether the aging test of the heating assembly passes according to the initial resistance value and the current resistance value comprises:

When the power supply module is connected to the heating assembly to be tested but does not output an electric parameter of a set value to the heating assembly, the initial resistance value of the heating assembly is obtained by using the resistance value determination module. The control module controls the power supply module to output or stop outputting the electric parameter of the set value to the heating assembly to be tested in cycles, and the number of cycles is obtained. When the number of cycles reaches a set number, the current resistance value of the heating assembly completing the cycles is obtained by the resistance value determination module, and finally whether the aging test of the heating assembly passes is determined according to the initial resistance value and the current resistance value. The conventional aging test usually relies on a long-time high-temperature cycle, while the present application can quickly identify the performance change of the heating assembly by using the resistance value ratio, thereby reducing unnecessary long-time cycles. In this way, the aging test can be completed in a short time, the test period is optimized, and more timely feedback is provided. Moreover, the aging test is performed by using the resistance value change, which does not rely on a complex temperature curve or an external measuring device, and can be tested in different use environments, thereby being more adaptable.

Also, each of the steps or acts in the method descriptions can be performed in any suitable order, or in parallel, unless otherwise specified. Therefore, the order in which the operations are described is not necessarily the order in which the operations are performed. The various sequences and processes described herein can be summarized as a method, a process, an article of manufacture, a data stream, and / or a computer-readable medium.

[0034] The terms "first", "second", and the like, as used in this description do not necessarily have any temporal meanings. The terms "connect", "couple", and the like, unless otherwise specified, include both direct and indirect connections (couplings).

[0035] For the aging failure test of the heating object, generally, because of the expansion during heating, the expansion coefficients of different materials are different, which can cause the materials to be pressed or separated, thereby destroying the original structure of the materials and causing failure. Therefore, during the aging test, rapid heating and cooling of the heating assembly can determine the life stability of the heating assembly, and can greatly reduce the test time.

[0036] Referring to Figure 1 and Figure 2 In one embodiment, an aging test device 100 for a heating assembly is provided, wherein the heating assembly is a component for heating aerosol in an aerosol generating device. The aging test device 100 includes a power supply module 110, a resistance determination module 120, a timing module 130, a control module 140, and a heat dissipation module 150.

[0037] In one embodiment, the power module 110 is connected to the heating component to be tested, and is configured to output or stop outputting a set value of an electrical parameter to the heating component.

[0038] In one embodiment, when the power module 110 is initially connected to the heating component, and the power module 110 has not yet outputted the set value of the electrical parameter to the heating component, the resistance determining module 120 obtains the initial resistance value R0 of the heating component.

[0039] In one embodiment, the timing module 130 obtains a first set time duration for which the power module 110 outputs the set value of the electrical parameter to the heating component, and obtains a second set time duration for which the power module 110 stops outputting the set value of the electrical parameter to the heating component.

[0040] In one embodiment, the power module 110 outputs the set value of the electrical parameter to the heating component for the first set time duration so that the heating component can quickly reach a maximum temperature for use, and the power module 110 stops outputting the set value of the electrical parameter to the heating component for the second set time duration so that the heating component can quickly drop to a minimum temperature for use.

[0041] It should be noted that the set value of the electrical parameter needs to be greater than or equal to a maximum value of the electrical parameter reached by the heating component during operation, and the electrical parameter outputted by the power module 110 to the heating component can be voltage or power. The first set time duration and the second set time duration are the first set time duration and the second set time duration obtained by the heating component when the heating component reaches the set maximum temperature and the set minimum temperature during testing, and the first set time duration and the second set time duration are determined during testing, so that only the determined first set time duration and the second set time duration need to be inputted during the burn-in test.

[0042] In one embodiment, in order to shorten the second set time duration, a fan or other component for heat dissipation can be added during testing of the heating component to increase the speed of reducing the temperature of the heating component, so that the second set time duration can be shortened. Then, a heat dissipation module 150 can be added to the burn-in test device 100, and the heat dissipation module 150 is used to dissipate heat from the heating component, so that the heating component can drop to the set minimum temperature within the set second set time duration which has been shortened.

[0043] It should be noted that if no fan or other heat dissipation component is added during testing of the heating component, then the heat dissipation module 150 can be selected not to be provided in the burn-in test device 100, or the heat dissipation module 150 provided in the burn-in test device 100 can be turned off.

[0044] In one embodiment, the control module 140 controls the power module 110 to output or stop outputting the electric parameter of the set value to the heating assembly in cycles, and obtains the cycle number. When the cycle number reaches a set number, the resistance value determination module 120 obtains the current resistance value R01 of the heating assembly when the cycle is completed, and the control module 140 determines whether the aging test of the heating assembly passes according to the initial resistance value R0 and the current resistance value R01.

[0045] In one embodiment, the control module 140 controls the power module 110 to output or stop outputting the electric parameter of the set value to the heating assembly in cycles, and obtains the cycle number. When the cycle number reaches a set number, the resistance value determination module 120 obtains the current resistance value R01 of the heating assembly when the cycle is completed, and the control module 140 determines whether the aging test of the heating assembly passes according to the initial resistance value R0 and the current resistance value R01.

[0046] It should be noted that the control module 140 can control the power module 110 to output or stop outputting the electric parameter of the set value to the heating assembly in cycles in the following manner: the control module 140 controls the on-off of the power module 110; or the control module 140 and the power module 110 are provided with a conduction switch, and the control module 140 controls the on-off of the conduction switch to control the power module 110 to output or stop outputting the electric parameter of the set value to the heating assembly in cycles.

[0047] In one embodiment, the control module 140 determines whether the aging test of the heating assembly passes according to the initial resistance value R0 and the current resistance value R01 in the following manner: the control module 140 calculates the ratio of the current resistance value R01 to the initial resistance value R0, and when the ratio is within a set ratio range, the aging test of the heating assembly passes; when the ratio is not within the set ratio range, the aging test of the heating assembly does not pass. In this application, the set ratio range is 0.95-1.05, and in engineering practice, the set ratio range can be set according to different models of the aerosol generating device.

[0048] It should be noted that by monitoring the change of the resistance value of the heating assembly in real time, the performance degradation of the heating assembly can be intuitively reflected. The resistance value of the heating assembly usually changes with aging, especially in long-term thermal cycles. An increase in the resistance value usually means that the heating element is damaged or the internal structure is changed. Therefore, using the resistance value ratio to evaluate the aging degree of the heating assembly is not only simple, but also can accurately capture early degradation information of the device.

[0049] Reference is made to Figure 3 In an embodiment, a method for testing the aging of a heating assembly is provided. The heating assembly in the method is also applied to an aerosol generating device. The method comprises the following steps.

[0050] Step S10: Obtain the initial resistance of the heating assembly when the heating assembly is not outputting the set value of the electrical parameter.

[0051] In an embodiment, the initial resistance R0 of the heating assembly is obtained when the heating assembly has not obtained the set value of the electrical parameter.

[0052] Step S20: Output or stop outputting the set value of the electrical parameter to the heating assembly and obtain the number of cycles.

[0053] In an embodiment, when the duration of outputting the set value of the electrical parameter to the heating assembly reaches a first set duration, the output of the set value of the electrical parameter to the heating assembly is stopped. When the duration of stopping the output of the set value of the electrical parameter to the heating assembly reaches a second set duration, a cycle is completed, and the number of cycles is incremented by one. The output of the set value of the electrical parameter to the heating assembly for the first set duration is to enable the heating assembly to quickly reach the maximum temperature for use, and the stopping of the output of the set value of the electrical parameter to the heating assembly for the second set duration is to enable the heating assembly to quickly drop to the minimum temperature for use.

[0054] It should be noted that the set value of the electrical parameter needs to be greater than or equal to the maximum value of the electrical parameter reached by the heating assembly during operation. The electrical parameter output to the heating assembly can be voltage or power. The first set duration and the second set duration are the first set duration and the second set duration obtained by the heating assembly when the heating assembly reaches the set maximum temperature and minimum temperature during testing. The first set duration and the second set duration are determined during testing, so that only the determined first set duration and second set duration need to be input during the aging test.

[0055] Step S30: Obtain the current resistance of the heating assembly after completing the cycle, and determine whether the aging test of the heating assembly passes according to the initial resistance and the current resistance.

[0056] In an embodiment, when the number of cycles reaches a set number, the current resistance R01 of the heating assembly after completing the cycle is obtained. At this time, whether the aging test of the heating assembly passes is determined according to the initial resistance R0 and the current resistance R01. The set number is the maximum number of uses for normal operation of the aerosol generating device.

[0057] In an embodiment, the control module 140 calculates a ratio of the current resistance value R01 to the initial resistance value R0, and when the ratio is within a set ratio range, the aging test of the heating assembly is passed; when the ratio is not within the set ratio range, the aging test of the heating assembly is failed. In the present application, the set ratio range is 0.95-1.05, and in engineering practice, the set ratio range can be set correspondingly according to different models of the aerosol generating device.

[0058] The aging test method and device of the heating assembly provided in the present application can improve the test efficiency, reduce the test cost, and help to find potential problems more quickly through real-time feedback, and have strong operability and flexibility.
