[0032] Example 1

[0033] refer to Figure 1 This document illustrates a flowchart of a short-circuit detection method for an aerosol generating device according to an embodiment of the present invention. The method includes:

[0034] S110: Determine whether the aerosol generating device is in the on state.

[0035] S120: In response to the aerosol generating device being in the on state, detect the initial voltage of the battery of the aerosol generating device.

[0036] As an example, when the aerosol generator is turned on, that is, before the aerosol generator is ready to output, the initial voltage V1 of the battery is detected and saved. The initial voltage V1 is typically set to 3.8-4.5V. The purpose of detecting the initial voltage is to compare it with the subsequently acquired real-time battery voltage. Since the battery voltage tends to decrease during the atomization process of the aerosol generator, and a short circuit will cause a sharp drop in voltage, detecting the initial voltage and using it as a reference facilitates subsequent detection of short circuits.

[0037] S130: Determine whether the cumulative detection time has reached the time threshold.

[0038] As an example, the cumulative detection time can be understood as the duration during which the aerosol generating device is in the on state, or as the cumulative time after the initial voltage is acquired while the aerosol generating device is in the on state. The time threshold here can be preset to 10ms. It should be noted that this time threshold is not limited here, and relevant technical personnel can change the setting of this time threshold based on actual needs.

[0039] S140: In response to the cumulative detection duration reaching a time threshold, obtain the real-time voltage of the battery of the aerosol generating device.

[0040] As an example, if the time threshold is set to 10ms, the real-time battery voltage Vs will be detected every 10ms during the output process of the aerosol generating device.

[0041] S150: Determine whether the real-time voltage meets the first preset condition.

[0042] As an example, the first preset condition is that the difference between the real-time voltage and the initial voltage is greater than a preset voltage drop value, where the preset voltage drop value Vt can be 0.2-0.3V. For example, if the initial voltage V1 is 3.8V and the detected real-time voltage Vs is 3.7V, then V1-Vs = 0.1V, and the real-time voltage does not meet the first preset condition. If the initial voltage V1 is 3.8V and the detected real-time voltage Vs is 3.4V, then V1-Vs = 0.4V, and the real-time voltage meets the first preset condition.

[0043] S160: In response to the real-time voltage meeting the first preset condition, the first counter increments by one.

[0044] As an example, when the difference between the real-time voltage Vs and the initial voltage V1 is greater than the preset voltage drop value Vt, the first counter will increment by one. The initial value of the first counter can be set to 0.

[0045] If the real-time voltage Vs does not meet the first preset condition, the circuit is considered to be working normally, and the real-time voltage Vs will continue to be acquired for subsequent judgment.

[0046] S170: Determine whether the real-time voltage meets the first preset condition N times consecutively.

[0047] S180: In response to the real-time voltage satisfying the first preset condition N times consecutively, determine whether the cumulative count of the first counter satisfies the second preset condition.

[0048] As an example, determine whether the difference between the real-time voltage Vs and the initial voltage V1 is greater than the preset voltage drop value Vt for N consecutive times. If so, determine whether the cumulative count C of the first counter is greater than or equal to N.

[0049] S190: In response to the first counter accumulating a count that meets the second preset condition, control the aerosol generating device to stop working.

[0050] As an example, the second preset condition is that the cumulative count of the first counter is greater than N. N can be set to 3, meaning that if the difference between the real-time voltage Vs and the initial voltage V1 is greater than the preset voltage drop value Vt for three consecutive times, and the cumulative count C of the first counter is also greater than or equal to 3, then the aerosol generating device is controlled to stop working. In other words, only when both the first and second preset conditions are met simultaneously will it be determined that the aerosol generating device has a short circuit, causing it to stop working. Specifically, an alarm can be issued on the aerosol generating device.

[0051] S1100: In response to the real-time voltage not satisfying the first preset condition for N consecutive times, the first counter is reset to zero.

[0052] As an example, if the difference between Vs and V1 is less than the preset voltage drop value Vt in any of N consecutive samplings, the first counter C is reset to zero, indicating that the previous short circuit was a false alarm, and the aerosol generating device resumes normal operation. That is, when N is 3, if the difference between Vs and V1 is less than the preset voltage drop value Vt even once in three samplings, the first counter will restart counting.

[0053] S1110: In response to the first counter's cumulative count not meeting the second preset condition, control the aerosol generating device to operate normally.

[0054] The above embodiment determines whether the aerosol generating device is in a short-circuit state by comparing the difference between the real-time voltage Vs and the initial voltage V1 with a preset voltage drop value Vt. This effectively avoids errors caused by sudden voltage drops, further ensuring the accuracy of determining whether the aerosol generating device is in a short-circuit state.

[0055] Example 2

[0056] refer to Figure 2 This document illustrates a flowchart of a short-circuit detection method for another aerosol generating apparatus provided in an embodiment of the present invention. The method further includes:

[0057] S210: Determine whether the aerosol generating device is in the on state.

[0058] S220: In response to the aerosol generating device being in the on state, detect the initial voltage of the battery of the aerosol generating device.

[0059] S230: Determine whether the cumulative detection time has reached the time threshold.

[0060] S240: In response to the cumulative detection duration reaching a time threshold, obtain the real-time voltage of the battery of the aerosol generating device.

[0061] As an example, steps S210-S240 are the same as steps S110-S140 in Embodiment 1 above, and will not be repeated here.

[0062] S250: Compare whether the real-time voltage is less than the preset instantaneous short-circuit voltage threshold.

[0063] As an example, the instantaneous short-circuit voltage threshold V L It can be set to 2.2V, that is, comparing the real-time voltage Vs with the instantaneous short-circuit voltage threshold V. L Size.

[0064] S260: When the real-time voltage is less than the preset instantaneous short-circuit voltage threshold, control the aerosol generating device to stop working.

[0065] As an example, if the real-time voltage Vs is less than the instantaneous short-circuit voltage threshold V L If the voltage of the aerosol generator is too low, it indicates that a short circuit has occurred in the aerosol generator. The aerosol generator can then be stopped without further inspection.

[0066] S270: When the real-time voltage is greater than the preset instantaneous short-circuit voltage threshold, determine whether the real-time voltage meets the first preset condition.

[0067] S280: In response to the real-time voltage meeting the first preset condition, the first counter increments by one.

[0068] S290: Determine whether the real-time voltage meets the first preset condition N times consecutively.

[0069] S2100: In response to the real-time voltage satisfying the first preset condition N times consecutively, determine whether the cumulative count of the first counter satisfies the second preset condition.

[0070] S2110: In response to the first counter accumulating a count that meets the second preset condition, control the aerosol generating device to stop working.

[0071] S2120: In response to the real-time voltage not satisfying the first preset condition for N consecutive times, the first counter is reset to zero.

[0072] S2130 responds to the first counter's cumulative count not meeting the second preset condition by controlling the aerosol generating device to operate normally.

[0073] As an example, if the real-time voltage Vs is greater than the preset instantaneous short-circuit voltage threshold V... L If the above steps S270-S2130 are the same as steps S150-S1110 in the embodiment, they will not be described again here.

[0074] The above embodiments, by directly judging the real-time voltage, simplify the judgment process and make the judgment faster while ensuring the accuracy of judging whether the aerosol generating device is in a short circuit state, effectively preventing serious consequences caused by slow judgment.

[0075] Example 3

[0076] refer to Figure 3 This document illustrates a flowchart of a short-circuit detection method for an aerosol generating apparatus according to an embodiment of the present invention. The method further includes:

[0077] S310: Determine whether the aerosol generating device is in the on state.

[0078] S320: In response to the aerosol generating device being in the on state, detect the initial voltage of the battery of the aerosol generating device.

[0079] S330: Determine whether the cumulative detection time has reached the time threshold.

[0080] S340: In response to the cumulative detection duration reaching a time threshold, obtain the real-time voltage of the battery of the aerosol generating device.

[0081] As an example, steps S310-S340 are the same as steps S110-S140 in Embodiment 1 above, and will not be repeated here.

[0082] S350: Determine whether the real-time voltage meets the third preset condition.

[0083] As an example, the third preset condition is that the real-time voltage value Vs is less than the preset instantaneous short-circuit voltage threshold V. L .

[0084] S360: When the real-time voltage meets the third preset condition, the second cumulative counter increments by one.

[0085] As an example, when the real-time voltage Vs is less than the preset instantaneous short-circuit voltage threshold V L When the time is up, the second counter will increment by one. The initial value of the second counter can be set to 0.

[0086] If the real-time voltage Vs does not meet the third preset condition, the circuit is considered to be working normally. It is then determined whether the real-time voltage Vs meets the first preset condition, and based on the determination result, it is chosen to either continue acquiring the real-time voltage Vs or increment the first counter count by one.

[0087] S370: Determine whether the real-time voltage satisfies the third preset condition M times consecutively.

[0088] S380: When the real-time voltage meets the third preset condition M times consecutively, determine whether the cumulative count of the second counter meets the fourth preset condition.

[0089] As an example, determine whether the real-time voltage Vs is less than the preset instantaneous short-circuit voltage threshold V for M consecutive times. L If so, then determine whether the cumulative count C2 of the second counter is greater than or equal to M, where M can be set to 2.

[0090] S390: When the cumulative count of the second counter meets the fourth preset condition, the aerosol generating device is controlled to stop working.

[0091] As an example, the fourth preset condition is that the cumulative count of the second counter is greater than M, that is, when the real-time voltage Vs is less than the preset instantaneous short-circuit voltage threshold V for two consecutive times. L If C2 is greater than or equal to M, then the aerosol generating device is controlled to stop working.

[0092] S3100: When the real-time voltage does not meet the third preset condition M times consecutively, the cumulative count of the second counter is cleared to zero.

[0093] S3110: When the cumulative count of the second counter does not meet the fourth preset condition, control the aerosol generating device to work normally.

[0094] S3120: When the real-time voltage does not meet the third preset condition, determine whether the real-time voltage meets the first preset condition.

[0095] As an example, if the real-time voltage does not meet the third preset condition, then proceed to step S150 to determine whether the real-time voltage meets the first preset condition.

[0096] S3130: In response to the real-time voltage meeting the first preset condition, the first counter increments by one.

[0097] S3140: Determine whether the real-time voltage meets the first preset condition N times consecutively.

[0098] S3150: In response to the real-time voltage satisfying the first preset condition N times consecutively, determine whether the cumulative count of the first counter satisfies the second preset condition.

[0099] S3160: In response to the first counter accumulating a count that meets the second preset condition, control the aerosol generating device to stop working.

[0100] S3170: In response to the real-time voltage not satisfying the first preset condition N times consecutively, the first counter is reset to zero.

[0101] S3180: In response to the first counter's cumulative count not meeting the second preset condition, control the aerosol generating device to operate normally.

[0102] The subsequent steps S3130-S3180 are the same as steps S160-S1110 in Example 1, and will not be described again here.

[0103] The above embodiments employ two parallel technical solutions: one determines whether the aerosol generating device is in a short-circuit state based on the difference between the real-time voltage and the initial voltage; the other determines whether the aerosol generating device is in a short-circuit state based on the real-time voltage and a preset instantaneous short-circuit voltage threshold V. L This method determines whether the aerosol generator is in a short-circuit state. By employing two parallel technical solutions, the accuracy of short-circuit detection for the aerosol generator can be effectively guaranteed, further ensuring user safety.

[0114] The acquisition module 420 is adapted to acquire the initial voltage, real-time voltage and preset instantaneous short-circuit voltage threshold of the battery of the aerosol generating device in response to the aerosol generating device being in the on state.

[0115] As an example, the preset instantaneous short-circuit voltage threshold is calculated based on the initial voltage of the battery in the aerosol generating device; or the aerosol generating device stores a table corresponding to the initial voltage of the battery and the instantaneous short-circuit voltage threshold, so the preset instantaneous short-circuit voltage threshold can be obtained as long as the initial voltage of the battery is obtained; or the aerosol generating device directly stores the initial voltage of the battery and the preset instantaneous short-circuit voltage threshold. It should be noted that the specific method of obtaining the preset instantaneous short-circuit voltage threshold is not limited here, and relevant technical personnel can set the instantaneous short-circuit voltage threshold acquisition method according to actual needs.

[0121] The detection module 610 is suitable for detecting whether the aerosol generating device is in the on state.

[0122] The acquisition module 620 is adapted to acquire the initial voltage and real-time voltage of the battery of the aerosol generating device in response to the aerosol generating device being in the on state; or to acquire the initial voltage, real-time voltage and a preset instantaneous short-circuit voltage threshold of the battery of the aerosol generating device in response to the aerosol generating device being in the on state.

[0123] The judgment module 630 is suitable for determining whether a preset condition is met by comparing the difference between the real-time voltage and the initial voltage; and / or determining whether a preset condition is met by comparing the real-time voltage with a preset instantaneous short-circuit voltage threshold.

[0124] The verification module 650 is used to verify the condition by counting the number of times the preset condition is met when the judgment module 630 determines that the preset condition is met. When the count value reaches the preset value, the result is fed back to the judgment module 630.

[0125] As an example, when the judgment module 630 determines that the difference between the real-time voltage and the initial voltage is greater than a preset value and / or the judgment module 630 determines that the real-time voltage is less than the instantaneous short-circuit voltage threshold, a verification signal is sent to the verification module 650. The verification module 650 increments its count value by one, with the initial count value being zero. When the count value in the verification module 650 reaches a preset N or M, that is, when the verification module 650 verifies that the difference between the real-time voltage and the initial voltage is greater than the preset value N times consecutively, or when the verification module 650 verifies that the real-time voltage is less than the instantaneous short-circuit voltage threshold M times consecutively, the verification module 650 outputs a confirmation signal that the preset conditions are met to the judgment module 630. The judgment module 630 then outputs the final judgment result to the control module 640.

[0126] The control module 640 is suitable for controlling the aerosol generating device to turn on or off based on the judgment result of the judgment module.

That is, the judgment module 630 and the verification module 650 input and output to each other, and the other output of the judgment module 630 is connected to the input of the control module 540.
