[0002] At present, the aging of HBN (heat not burn) aerosol generating devices generally requires about 8,000 cycles according to the temperature curve. The temperature curve of the HBN aerosol generating device refers to the process curve of how the heating element inside the aerosol generating device heats up, maintains, and cools over time during the aging test or normal use. Although the temperature curve cycle can accurately evaluate the life and stability of the heating element, the entire aging test takes 3 to 4 months. This long cycle results in the inability to feedback the test results in a timely manner, delays the discovery and resolution of problems, and is not conducive to the rapid iteration and improvement of products. In addition, during the long aging test process, a large amount of temperature data and other performance indicator data will be generated. The data volume is huge and the processing difficulty is high, which increases the complexity and workload of the result analysis. Summary of the invention

[0010] When the duration for which the power module outputs the electrical parameters of the set value to the heating component reaches a first set duration, the control module controls the power module to stop outputting the electrical parameters of the set value to the heating component; when the duration for which the power module stops outputting the electrical parameters of the set value to the heating component reaches a second set duration, the control module completes a cycle.

[0011] In one embodiment, the aging test equipment further includes a heat dissipation module;

[0012] The heat dissipation module is used to dissipate heat for the heating component when the power supply module stops outputting the electrical parameters of the set value to the heating component.

In addition, the aging test is performed using the resistance change, which does not rely on complex temperature curves or external measurement equipment, and can be tested in different usage environments, and has stronger adaptability.

[0032] 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.

[0033] 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.

[0034] 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).

[0035] For aging failure tests of heated objects, it is generally because of expansion during heating. Different materials have different expansion coefficients, which will cause the materials to squeeze or separate, thereby destroying the original structure of the materials and causing failure. Therefore, during aging tests, the life stability of the heating components can be determined by quickly heating and cooling the heating components, which can also significantly reduce the test time.

[0036] Please refer to Figure 1 and Figure 2 In one embodiment, an aging test device 100 of a heating component is provided, wherein the heating component is a component in an aerosol generating device that heats the aerosol. The aging test device 100 includes a power 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 used to output or stop outputting electrical parameters of set values ​​to the heating component.

[0038] In one embodiment, when the power module 110 is connected to the heating component for the first time and the power module 110 has not yet output the electrical parameters of the set value to the heating component, the resistance determination module 120 obtains the current initial resistance R0 of the heating component.

[0039] In one embodiment, the timing module 130 obtains a first set duration for the power module 110 to output an electrical parameter of a set value to the heating component, and at the same time, the timing module 130 also obtains a second set duration for the power module 110 to stop outputting an electrical parameter of a set value to the heating component.

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

[0041] 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 when the heating component is working, wherein the electrical parameter output by the power module 110 to the heating component can be voltage or power. The first set time length and the second set time length are the first set time length and the second set time length obtained when the heating component reaches the set maximum temperature and the minimum temperature during the test of the heating component. The first set time length and the second set time length are determined during the test, so that only the determined first set time length and the second set time length need to be input in the aging test.

[0042] In one embodiment, in order to shorten the second set time, a fan or other heat dissipation component can be added when testing the heating component to increase the speed of lowering the temperature of the heating component, so that the second set time can be shortened. Then a heat dissipation module 150 can be added to the aging test device 100, and the heat dissipation module 150 is used to dissipate the heat of the heating component, so that the heating component can be reduced to the lowest temperature set during the measurement within the set shortened second set time.

[0043] It should be noted that if no heat dissipation components such as fans are added to the test of the heating component, the heat dissipation module 150 may not be provided in the aging test device 100 , or the provided heat dissipation module 150 may not be turned on in the aging test device 100 .

[0044] In one embodiment, the control module 140 controls the power module 110 to cyclically output or stop outputting the electrical parameters of the set value to the heating component, and obtains the number of cycles. When the number of cycles reaches the set number, the resistance determination module 120 obtains the current resistance R01 of the heating component after the cycle is completed. At this time, the control module 140 determines whether the aging test of the heating component has passed according to the initial resistance R0 and the current resistance R01.

[0045] In one embodiment, the control module 140 controls the power module 110 to cyclically output or stop outputting the electrical parameter of the set value to the heating component, specifically including: when the duration of the power module 110 outputting the electrical parameter of the set value to the heating component reaches a first set duration, the control module 140 controls the power module 110 to stop outputting the electrical parameter of the set value to the heating component, and when the duration of the power module 110 stopping outputting the electrical parameter of the set value to the heating component reaches a second set duration, a cycle is completed, and the number of cycles in the control module 140 is increased by one. The control module 140 controls the power module 110 to circulate the heating component in the above manner until the number of cycles reaches a set number, wherein the set number is the maximum number of times the aerosol generating device is normally used.

[0046] It should be noted that the control module 140 controls the power module 110 to cyclically output or stop outputting the electrical parameters of the set value to the heating component by the control module 140 using software to control the on and off of the power module 110, or a conduction switch is provided between the control module 140 and the power module 110, then the control module 140 can control the on and off of the conduction switch to control the power module 110 to cyclically output or stop outputting the electrical parameters of the set value to the heating component.

[0047] In one embodiment, the control module 140 determines whether the aging test of the heating component has passed according to the initial resistance value R0 and the current resistance value R01 in the following specific manner: the control module 140 calculates the ratio of the current resistance value R01 divided by the initial resistance value R0. When the ratio is within the set ratio range, the aging test of the heating component has passed; when the ratio is not within the set ratio range, the aging test of the heating component has failed. In the present application, the ratio range is set to 0.95-1.05. In engineering practice, the ratio range can be set accordingly according to different models of aerosol generating devices.

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

[0049] Please refer to Figure 3 In one embodiment, a method for testing an aging of a heating component is provided. The heating component in the method is also applied to an aerosol generating device. The method includes the following steps.

[0050] Step S10: obtaining the initial resistance value of the heating component when the electrical parameter of the set value is not output to the heating component to be tested.

[0051] In one embodiment, when the heating component has not yet obtained the electrical parameters of the set value, the initial resistance value R0 of the heating component is obtained.

[0052] Step S20: cyclically output or stop outputting the electrical parameters of the set value to the heating component, and obtain the number of cycles.

[0053] In one embodiment, when the duration of outputting the electrical parameter of the set value to the heating component reaches a first set duration, the electrical parameter of the set value to the heating component is stopped, and when the duration of stopping outputting the electrical parameter of the set value to the heating component reaches a second set duration, a cycle is completed, and the number of cycles is increased by 1. Outputting the electrical parameter of the set value to the heating component for the first set duration is to allow the heating component to quickly reach the highest temperature used, and stopping outputting the electrical parameter of the set value to the heating component for the second set duration is to allow the heating component to quickly drop to the lowest temperature used.

[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 when the heating component is working, wherein the electrical parameter output to the heating component can be voltage or power. The first set time length and the second set time length are the first set time length and the second set time length obtained when the heating component reaches the set maximum temperature and the minimum temperature during the test. The first set time length and the second set time length are determined during the test, so that only the determined first set time length and the second set time length need to be input in the aging test.

[0055] Step S30: obtaining the current resistance value of the heating component after completing the cycle, and determining whether the aging test of the heating component has passed according to the initial resistance value and the current resistance value.

[0056] In one embodiment, when the number of cycles reaches the set number, the current resistance value R01 of the heating component after the cycle is completed is obtained, and at this time, whether the aging test of the heating component has passed is determined based on the initial resistance value R0 and the current resistance value R01. The set number is the maximum number of times the aerosol generating device can be used normally.

[0057] In one embodiment, the control module 140 calculates the ratio of the current resistance R01 divided by the initial resistance R0. When the ratio is within the set ratio range, the aging test of the heating component passes; when the ratio is not within the set ratio range, the aging test of the heating component fails. In the present application, the set ratio range is 0.95-1.05. In engineering practice, the set ratio range can be set accordingly according to different models of aerosol generating devices.

[0058] The aging test method and equipment for a heating component provided in the present application can improve test efficiency, reduce test costs, and help discover potential problems more quickly through real-time feedback, and has strong operability and flexibility.
