[0059] Referring to

[0060] See Figures 1 - 4 , Figure 1 is a structural block diagram of an atomizing device provided by an embodiment of the present application; Figure 2 is a schematic diagram of functional modules of an atomizing device provided by an embodiment of the present application; Figure 3 is a curve graph of the frequency values output by the sensing element when the airway is blocked and / or leaking liquid and the frequency values output by the sensing element when the airway is not blocked and / or not leaking liquid under the same suction force of the user provided by a set of experimental data of the present application; Figure 4 is a schematic diagram of functional modules of an atomizing device provided by another embodiment of the present application.

[0061] See Figure 1, the atomizing device 300 includes a battery rod 100 and an atomizer 200. Among them, the atomizer 200 is used to heat and atomize the matrix to be atomized; the battery rod 100 is electrically connected to the atomizer 200, provides electrical energy for the atomizer 200, and controls the operation of the atomizer 200 so that the atomizer 200 heats and atomizes the matrix to be atomized to generate an aerosol. Among them, the atomizer 200 and the battery rod 100 can be integrally formed or can be detachably arranged.

[0062] Among them, the atomizer 200 may include a liquid storage chamber (not shown in the figure), an atomizing seat (not shown in the figure), an atomizing core (not shown in the figure), and a base (not shown in the figure). The liquid storage chamber is used to store the matrix to be atomized; the atomizing seat is embedded in the liquid storage chamber, the base covers the open end of the liquid storage chamber, and is connected to the atomizing seat to form an atomizing cavity. The atomizing core is arranged on the atomizing seat and can obtain the matrix to be atomized in the liquid storage chamber. The atomizing core atomizes the matrix to be atomized under the condition of being powered on to generate an aerosol for the user to use.

[0063] See Figure 2 , the atomizing device 300 is provided with a sensing element 10 for detecting the airflow change in the atomizing device 300, an air passage (not shown in the figure) communicating with the sensing element 10, and a control circuit 20 connected to the sensing element 10. Among them, the sensing element 10 is used to detect the airflow change in the air passage, and the control circuit 20 controls the atomizer 200 to heat and atomize the matrix to be atomized or stop heating and atomizing the matrix to be atomized according to the airflow change detected by the sensing element 10 in the air passage. Among them, the sensing element 10 and the control circuit 20 can be arranged in the atomizer 200, can also be arranged in the battery rod 100, or can also be separately arranged in the atomizer 200 and the battery rod 100, which is not limited here.

[0064] In this application, during the user's suction process, the sensing element 10 is used to obtain the current suction force D (negative pressure) of the user. The control circuit 20 is connected to the sensing element 10 and is used to determine the airway state of the atomizing device 300 according to the current suction force D so that the user can make corresponding operations according to the airway state, thereby improving the user experience. Among them, the software for detecting the airway state of the atomizing device 300 can be in the atomizing device 300 or can be externally connected to the atomizing device 300 through an external device. The external connection method is not limited and can be a wired connection or a wireless connection.

[0065] Specifically, during the use of the atomization device 300, there may be abnormal states of the airway of the atomization device 300 caused by foreign object blockage, liquid leakage from the liquid storage chamber, aerosol condensate backflow, or other situations, resulting in a poor user suction experience. In severe cases, the atomization device 300 may not be able to be used normally. It can be understood that when the airway is in a normal state, the suction force of the user each time when sucking the atomization device 300 is basically unchanged. Compared with the state where the airway of the atomization device 300 is not blocked and / or there is no liquid leakage, when abnormal states such as blockage and / or liquid leakage occur in the airway of the atomization device 300, although the user uses the same suction force, the change in the airflow in the airway will decrease. The sensing element 10 detects that the change in the airflow in the airway decreases. Specifically, the frequency value or pressure difference value obtained by the sensing element 10 becomes smaller, resulting in a decrease in the satisfaction of the user when sucking the atomization device.

[0066] Since the suction force of a specific user group each time when sucking the atomization device 300 is basically within a certain range. For example, the vital capacity of adult men in a certain area is within a certain range. Therefore, in one embodiment, the suction forces of multiple users when sucking the atomization device 300 multiple times can be obtained in advance through a large number of experiments, and then a standard value can be calculated. For example, the average suction force is used as the standard value. The standard value is stored in the memory in advance so that each time the user sucks the atomization device 300, the sensing element 10 obtains the current suction force D of the user, and the control circuit 20 judges and compares the current suction force D with the pre-stored standard value. If the current suction force D obtained by the sensing element 10 is greater than or equal to the standard value, it indicates that there is no abnormal state of blockage and / or liquid leakage in the airway of the atomization device 300; if the current suction force D obtained by the sensing element 10 is less than the standard value, it indicates that there is an abnormal state of blockage and / or liquid leakage in the airway of the atomization device 300. To avoid errors, the current suction force D of the user can also be obtained continuously multiple times for multiple judgments. If the number of times the current suction force D is less than the standard value is greater than a threshold, it is determined that the airway is abnormal. Further, multiple different standard value levels can also be set according to the range of the vital capacity of ordinary users, so that users can select the atomization device 300 with an appropriate standard value according to their own vital capacity.

[0067] Considering the differences in the vital capacity and suction habits of each user, there may be errors in pre-storing standard values in advance. In another embodiment, the suction force of the actual user of the atomizing device 300 is obtained to obtain the standard value. Specifically, the sensing element 10 obtains a plurality of suction forces during the user's use, such as five, ten, or fifteen. The control circuit 20 calculates the average suction force of the plurality of suction forces as the standard value, and when the user subsequently suctions the atomizing device 300, determines the magnitude of the current suction force D and the standard value. If the current suction force D is greater than or equal to the standard value, it indicates that the airway of the atomizing device 300 is normal; if the current suction force D is less than the standard value, it indicates that the airway of the atomizing device 300 is abnormal. It can be understood that by obtaining the suction force of the actual user of the atomizing device 300 to obtain the standard value, the judgment is made more accurate.

[0068] Specifically, in this application, the sensing element 10 obtains the current suction force D of the user, and the control circuit 20 determines the airway state of the atomizing device 300 according to the current suction force D, thereby ensuring a better user experience.

[0069] Among them, the sensing element 10 can be a frequency silicon microphone, a frequency microphone head, or a differential pressure sensor, and is used to detect the airflow or differential pressure change in the atomizing device 300. In this application, the frequency value detected by the frequency silicon microphone or the frequency microphone head, or the differential pressure value detected by the differential pressure sensor is used to reflect the user's suction force. This application can also use any other value that can be converted into an electrical value to reflect the user's suction force.

[0070] In one embodiment, the sensing element 10 is a frequency output sensing element. For example, a frequency silicon microphone or a frequency microphone head can output a frequency value F during operation, which is used to generate an initial frequency value F0 when the user is not suctioning, and a current frequency value F1 based on the current suction force D when the user is suctioning.

[0071] Specifically, when the sensing element 10 is working normally, it will continuously output a frequency value F. When the user does not inhale, the frequency value F generated by the sensing element 10 is the initial frequency value F0. Among them, according to the characteristics of different sensing elements 10, the values of the initial frequency values F0 of different sensing elements 10 can be the same or different. When the user uses the atomizing device 300, the sensing element 10 obtains the user's inhalation force and generates a corresponding current frequency value F1. Among them, one inhalation usually lasts for 3-5 seconds. Therefore, during one inhalation process, multiple frequency values F will be generated. Whether the airway of the atomizing device 300 is blocked or leaking can be set according to the characteristics of the customized sensing element 10 by whether the frequency value F increases or decreases. If the characteristic of the sensing element 10 is that the greater the inhalation force, the greater the generated frequency value F, then as the inhalation force increases, the frequency value of the frequency value F will increase, and as the inhalation force decreases, the frequency value of the frequency value F will decrease. That is, the inhalation force is positively correlated with the frequency value generated by the sensing element 10. If the characteristic of the sensing element 10 is that the greater the inhalation force, the smaller the generated frequency value F, then as the inhalation force increases, the frequency value of the frequency value F will decrease, and as the inhalation force decreases, the frequency value of the frequency value F will increase. That is, the inhalation force is negatively correlated with the frequency value generated by the sensing element 10. This application mainly takes the positive correlation between the inhalation force and the frequency value generated by the sensing element 10 as an example for illustration.

[0072] Among them, the sensing element 10 also has a trigger frequency value F3 corresponding to the minimum inhalation force for triggering an interrupt signal. Among them, according to the characteristics of different sensing elements 10, the values of the trigger frequency values F3 of different sensing elements 10 can be the same or different. When the current inhalation force D is greater than the initial frequency value F0 and less than the trigger frequency value F3, the atomizing device 300 does not atomize and heat. The control circuit 20 is used to determine the airway state of the atomizing device 300 according to the current frequency value F1.

[0073] Specifically, referring to Figure 3 , curve 1 represents the user's inhalation force curve when the user inhales the atomizing device 300, curve 2 represents the frequency value curve output by the sensing element 10 when the airway is not blocked and / or not leaking under the inhalation force of curve 1, and curve 3 represents the frequency value curve output by the sensing element 10 when the airway is blocked and / or leaking under the inhalation force of curve 1. Through Figure 3 it can be known that under the same inhalation force, the frequency value F output by the sensing element 10 when the airway is not blocked and / or not leaking is greater than the frequency value F output by the sensing element 10 in abnormal states such as when the airway is blocked and / or not leaking.

[0074] Among them, the sensing element 10 is further configured to output a low-level signal when the user does not suck the atomizing device 300; and output a high-level signal when the user sucks the atomizing device 300. Specifically, the sensing element 10 will continuously output a level signal during normal operation. When the user does not suck the atomizing device 300, the airflow and air pressure in the atomizing device 300 do not change, and the level signal output by the sensing element 10 is a low level. When the user sucks the atomizing device 300, the airflow and air pressure in the atomizing device 300 change, and the level signal output by the sensing element 10 becomes a high level. The control circuit 20 is further configured to detect the level signal output by the sensing element 10. When the control circuit 20 detects that the level signal of the sensing element 10 changes from a low level to a high level, it controls the atomizer 200 to operate; when the control circuit 20 detects that the level signal of the sensing element 10 changes from a high level to a low level, it controls the atomizer 200 to stop operating.

[0075] In an embodiment of the present application, each time the user sucks the atomizing device 300, the control circuit 20 is further configured to obtain a plurality of frequency values F during each sucking process, and obtain the maximum frequency value Fmax among them. It can be understood that N suckings correspond to N maximum frequency values Fmax. Based on the N maximum frequency values Fmax, the maximum frequency average value X is obtained, and the maximum frequency average value X is compared with the maximum current frequency value F2 among the plurality of current frequency values F1 corresponding to the current sucking force D to determine the airway state of the atomizing device 300. Among them, since the sucking force of the user each time sucking the atomizing device is not fixed, therefore, the N maximum frequency values Fmax can be exactly the same, not exactly the same, or completely different.

[0076] In a specific embodiment, the maximum current frequency value F2 among the multiple current frequency values F1 corresponding to the current suction force D is the maximum frequency value Fmax among the multiple frequency values F corresponding to the suction force of any suction after N suctions. That is, the control circuit 20 obtains the maximum frequency value Fmax among the multiple frequency values F corresponding to the suction force of any suction after obtaining the maximum frequency average value X. Specifically, when the atomization device 300 is first used, there will be no problems of airway blockage and / or liquid leakage in the airway of the atomization device 300. To ensure the accuracy of judging the airway state of the atomization device 300, the control circuit 20 can be used to continuously obtain ten maximum frequency values Fmax generated by ten suctions when the atomization device 300 is first used, and obtain the maximum frequency average value X based on the ten maximum frequency values Fmax. Thus, during the subsequent use of the atomization device 300 by the user, if the maximum current frequency value F2 among the multiple current frequency values F1 corresponding to the user's current suction force D is greater than or equal to the maximum frequency average value X, it is determined that the airway of the atomization device 300 is normal; if the maximum frequency value Fmax of the multiple current frequency values F1 corresponding to the user's current suction force D is less than the maximum frequency average value X, it is determined that the airway of the atomization device 300 is abnormal. For example, the control circuit 20 calculates the maximum frequency average value X by taking the ten maximum frequency values Fmax generated by the 1st - 10th suctions, and then compares the maximum frequency value Fmax generated by any subsequent suction with the maximum frequency average value X calculated from the 1st - 10th suctions to judge the airway state of the atomization device 300.

[0077] In another specific embodiment, the maximum current frequency value F2 among the multiple current frequency values F1 corresponding to the current suction intensity D is the maximum frequency value Fmax among the multiple frequency values F corresponding to the suction intensity of the next suction after N suctions. That is, the control circuit 20 obtains the maximum frequency value Fmax among the multiple frequency values F corresponding to the suction intensity of the next suction after obtaining the maximum frequency average value X. Specifically, considering that when different users use the same atomizing device 300, due to the difference in the suction intensity of different users, using the same maximum frequency average value X may cause judgment errors. In this embodiment, the control circuit 20 is configured to obtain the maximum frequency value Fmax among the multiple frequency values F each time the user suctions, so as to obtain multiple maximum frequency values Fmax, and obtain the maximum frequency average value X based on the multiple maximum frequency values Fmax. Thus, the control circuit 20 obtains the maximum frequency average value X according to the N maximum frequency values Fmax before the current suction, achieving the purpose of real-time updating of the maximum frequency average value X. For example, the control circuit 20 calculates the maximum frequency average value X by taking the maximum frequency values Fmax generated by 1 to 10 suctions, compares the maximum frequency value Fmax generated by the 11th suction with the maximum frequency average value X to judge the airway state of the atomizing device 300, and then the control circuit calculates the maximum frequency average value Y by taking the maximum frequency values Fmax generated by 2 to 11 suctions, and compares the maximum frequency value Fmax generated by the 12th suction with the maximum frequency average value Y to judge the airway state of the atomizing device 300. So that every time the user suctions the atomizing device 300, the judgment standard is the maximum frequency average value obtained from the previous 10 suctions before this suction, improving the accuracy of judging the airway state of the atomizing device 300. It should be noted that although there are certain differences in the maximum frequency values Fmax generated by the suction intensities of different users, the differences are within a relatively small range, and the change in the maximum frequency value Fmax obtained by the sensing element 10 is not very large. However, the abnormal airway state caused by airway blockage / liquid leakage will cause a large change in the maximum frequency value Fmax of the user obtained by the sensing element 10. Therefore, by setting a reasonable threshold, it is possible to distinguish whether the change in the maximum frequency value Fmax is caused by the difference in the suction intensity of different users or by airway abnormalities.

[0078] In yet another specific embodiment, the maximum current frequency value F2 among the multiple current frequency values F corresponding to the current suction force D is the average value of the M maximum frequency values Fmax among the multiple frequency values F corresponding to the suction force in the next M suctions (M > 1) after N suctions. That is, after the control circuit 20 obtains the maximum frequency average value X, it calculates the average value of the M maximum frequency values Fmax among the multiple frequency values F corresponding to the suction force in the next M suctions. Specifically, the control circuit 20 is configured to obtain the maximum frequency value Fmax among the multiple frequency values F each time the user suctions, so as to obtain multiple maximum frequency values Fmax, and obtain the maximum frequency average value X based on the multiple maximum frequency values Fmax; the maximum current frequency value F2 is the average value of the M maximum frequency values Fmax generated by the M suctions after the control circuit 20 obtains the maximum frequency average value X. For example, the control circuit 20 calculates the maximum frequency average value X by taking the maximum frequency values Fmax generated by the 1st - 10th suctions, calculates the average value Y by taking the maximum frequency values Fmax generated by the 11th - 20th suctions, calculates the maximum frequency average value Z by taking the maximum frequency values Fmax generated by the 21st - 30th suctions, compares the maximum frequency average value X with the average value Y to determine the airway state of the atomization device 300, compares the maximum frequency average value Y with the average value Z to determine the airway state of the atomization device 300, and so on. In this embodiment, by increasing the sampling data of the maximum current frequency value F2, the accuracy of judging the airway state of the atomization device 300 can be effectively improved.

[0079] See Figure 4 , in a specific embodiment, the atomization device 300 further includes a counter 30. The counter 30 is configured to record the number of times of obtaining the maximum frequency value Fmax of the frequency value F. The control circuit 20 is configured to calculate the maximum frequency average value X in response to the number of times of obtaining the maximum frequency value Fmax of the frequency value F being greater than or equal to a second preset threshold B. Wherein, the value range of the second preset threshold B can be 5 - 15. For example, the counter 30 records the number of times of obtaining the maximum frequency value Fmax of the frequency value F, and the control circuit 20 calculates the maximum frequency average value X in response to the number of times of obtaining the maximum frequency value Fmax of the frequency value F being greater than or equal to 10 times. Specifically, the calculation formula for the maximum frequency average value X is:

[0080]

[0081] Wherein, NFmax represents the sum of N maximum frequency values, and the N maximum frequency values Fmax can be the same, not completely the same, or completely different.

[0082] Among them, the control circuit 20 is further configured to compare the difference between the maximum frequency average value X and the maximum current frequency value F2 with a first preset threshold A, and in response to the difference between the maximum frequency average value X and the maximum current frequency value F2 being greater than the first preset threshold A, determine the airway state of the atomizing device 300. Specifically, if the maximum frequency average value X is greater than the maximum current frequency value F2, and the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A, it is determined that the airway of the atomizing device 300 is abnormal. For example, the maximum current frequency value F2 is 2800 Hz, the maximum frequency average value X is 3000 Hz, and the first preset threshold A is 100 Hz, that is, the difference between the maximum frequency average value X and the maximum current frequency value F2 is 200 Hz, and the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A, then it is determined that the airway of the atomizing device 300 is abnormal.

[0083] Among them, the first preset threshold A can be a positive number or a negative number, because whether it is represented by the frequency value F increasing or decreasing to indicate blockage or leakage can be set according to the characteristics of the customized sensing element 10. If the characteristic of the sensing element 10 is that the suction force is positively correlated with the generated frequency value F, the first preset threshold A is a positive number; if the characteristic of the sensing element 10 is that the suction force is negatively correlated with the generated frequency value F, the first preset threshold A is a negative number.

[0084] In a specific embodiment, the control circuit 20 is configured to compare the difference between the maximum frequency average value X and the maximum current frequency value F2 with the first preset threshold A multiple times, and the counter 30 is configured to record the number of times the difference between the maximum frequency average value X and the maximum current frequency value F2 is compared with the first preset threshold A. The control circuit 20 determines that the airway of the atomizing device 300 is abnormal in response to the number of times the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A being greater than a third preset threshold C. For example, the third preset threshold C is 10, and the control circuit 20 determines that the airway of the atomizing device 300 is abnormal in response to the number of times the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than 10.

[0085] Among them, the manner in which the control circuit 20 compares the difference between the maximum frequency average value X and the maximum current frequency value F2 with the first preset threshold A multiple times can be to continuously compare the difference between the maximum frequency average value X and the maximum current frequency value F2 with the first preset threshold A multiple times, or to compare the difference between the maximum frequency average value X and the maximum current frequency value F2 with the first preset threshold A every n frequency values F.

[0086] Among them, the comparison method in which the control circuit 20 responds to the number of times that the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A being greater than the third preset threshold C can be that the control circuit 20 continuously detects that the number of times the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A is greater than the third preset threshold C. For example, when the third preset threshold C is 10, and the control circuit 20 continuously detects that the number of times the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A is greater than 10, that is, the control circuit 20 continuously detects 10 times that the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A, it is determined that the airway of the atomizing device 300 is abnormal. If after the control circuit 20 continuously responds to the number of times that the difference between the maximum frequency average value X and the maximum current frequency value F2 is greater than the first preset threshold A being 9, the next maximum current frequency value F2 is greater than the maximum frequency average value X, or the difference between the maximum frequency average value X and the maximum current frequency value F2 is less than the first preset threshold A, the counter 30 starts counting anew. This can avoid misjudgment caused by the occasional reduction of the user's suction force and improve the accuracy of judgment.

[0087] In another embodiment of the present application, the atomizing device 300 further includes a counter 30, and the counter 30 is used to obtain the frequency value F obtained by the sensing element 10. Specifically, each time the user sucks the atomizing device 300, the counter 30 regularly detects a plurality of frequency values F corresponding to each suction force according to the first preset time T1. For example, taking the first preset time T1 as 0.2 s and the duration of one suction being 4 s as an example, during one suction process, the counter 30 regularly detects 20 frequency values F according to the first preset time T1.

[0088] Each time of suction, the control circuit 20 is further used to obtain the corresponding plurality of frequency values F, compare the plurality of frequency values F with the initial frequency value F0 and the trigger frequency value F3 of the sensing element 10 respectively, and in response to the plurality of frequency values F being greater than the initial frequency value F0 and less than the trigger frequency value F3, determine that the airway of the atomizing device 300 is blocked / leaking. For example, when the user is currently sucking the atomizing device 300, if the range of the plurality of current frequency values F1 corresponding to the current suction force D obtained by the counter 30 according to the first preset time T1 is 450 HZ - 550 HZ, the trigger frequency value F3 of the sensing element 10 is 600 HZ, and the initial frequency value F0 is 400 HZ, that is, the current frequency value F1 is greater than the initial frequency value F0 and less than the trigger frequency value F3, it is determined that the airway of the atomizing device 300 is abnormal and is completely blocked.

[0089] In another embodiment of the present application, each time the user sucks the atomization device 300, the control circuit 20 obtains a corresponding frequency value F every second preset time T2. For example, the second preset time T2 can be 0.2s, 0.4s, 0.6s, etc. During one suction process, the control circuit 20 can obtain M frequency values F and generate a data list H1 generated by one suction. For N suctions, the control circuit 20 can obtain N data lists H1 and N*M frequency values F. When the number of N suctions is greater than or equal to the fourth preset threshold P, based on the M frequency values F corresponding to every second preset time T2 in the N data lists H1, the average frequency M is obtained, and the N data lists H1 correspond to M average frequency values M. Among them, the value range of the fourth preset threshold P is 5-15 times. Taking one suction as 2 seconds and the second preset time T2 as 0.2s as an example, see Table 1:

[0090]

[0091]

[0092] Table 1

[0093] Further, the M average frequency values M are compared with the current data list H2 generated by multiple current frequency values F1 obtained from the current suction force D every second preset time T2 to determine the current airway state of the atomization device 300. The specific comparison method is as follows: the current frequency value F1 corresponding to 0.2s in the current data list H2 is compared with the first average frequency value M1 in the average frequency value M; the current frequency value F1 corresponding to 0.4s in the current data list H2 is compared with the second average frequency value M2 in the average frequency value M; the current frequency value F1 corresponding to 0.6s in the current data list H2 is compared with the third average frequency value M3 in the average frequency value M, and so on. It can be understood that by sampling the suction forces corresponding to multiple suctions to obtain multiple average frequency values M, M1-M10 in the multiple average frequency values M form the frequency change trend during one suction process. By comparing this frequency change trend with the current frequency value F at the corresponding time in the multiple current frequency values F corresponding to the current suction force D, the current airway state of the atomization device 300 can be determined more accurately.

[0094] In one embodiment, the control circuit 20 determines airway blockage / liquid leakage of the atomization device 300 in response to the M frequency averages all being greater than the corresponding current frequency value F1 in the current data list H2. Specifically, if the current frequency value F1 corresponding to 0.2 s is less than M1, the current frequency value F1 corresponding to 0.4 s is less than M2, the current frequency value F1 corresponding to 0.6 s is less than M3, and until the current frequency value F1 corresponding to 2.0 s is less than M10, it is determined that there is airway blockage / liquid leakage in the atomization device 300.

[0095] In some specific embodiments, the method for obtaining the current data list H2 is similar to the method for obtaining the maximum current frequency value F2 described above. The current data list H2 can be a current data list H2 generated from multiple current frequency values F1 obtained at every second preset time T2 corresponding to the suction force of any suction after N suctions. The current data list H2 can also be a current data list H2 generated from multiple current frequency values F1 obtained at every second preset time T2 corresponding to the suction force of the next suction after N suctions. Details are not described herein.

[0096] To increase the accuracy of judging airway abnormalities and increase the judgment data, the atomization device 300 further includes a counter 30. The counter 30 is used to record the number of times of comparing the M frequency averages M with the current data list H2 generated from multiple current frequency values F1 obtained at every second preset time T2 corresponding to the current suction force D. The control circuit 20 is further configured to compare the M frequency averages M with the current data list H2 multiple times, and determine airway blockage / liquid leakage of the atomization device 300 in response to the number of times that the M frequency averages M are all greater than the corresponding current frequency values F1 in the current data list H2 being greater than or equal to the fifth preset threshold Q. Among them, the value range of the fifth preset threshold Q can be 3 - 8 times. In a specific embodiment, the value of the fifth preset threshold Q is 3 times. Specifically, the M frequency averages M are obtained from the 1st - 10th suctions, the 11th suction is the current suction to obtain the current data list H2, and the control circuit 20 compares the M frequency averages M with multiple current frequency values F1 in the current data list H2; then the M frequency averages M are obtained from the 2nd - 11th suctions, the 12th suction is the current suction to obtain the current data list H2, and the control circuit 20 compares the M frequency averages M with multiple current frequency values F1 in the current data list H2; then the M frequency averages M are obtained from the 3rd - 12th suctions, the 13th suction is the current suction to obtain the current data list H2, and in response to the M frequency averages M being all greater than the corresponding multiple current frequency values F1 in the current data list H2 in three consecutive comparisons, it is determined that there is airway blockage / liquid leakage in the atomization device 300.

[0097] In one embodiment, the control circuit 20 is further configured to send a feedback signal to remind the user that the airway of the atomizing device 300 is blocked and / or leaking when the airway of the atomizing device 300 is abnormal, and processing is required. The feedback signal may be a prompt sound, an indicator light, etc.

[0098] The atomizing device 300 provided in the present application includes a sensing element 10 and a control circuit 20 connected to the sensing element 10. During the user's suction process, the sensing element 10 is configured to obtain the user's current suction force D, and the control circuit 20 is configured to determine the airway state of the atomizing device 300 according to the current suction force D. When the airway of the atomizing device 300 is abnormal, a feedback value is sent to prompt the user to process it in time, thereby ensuring a better user experience.

[0099] See Figure 5 , which is a schematic flowchart of the airway detection method of the atomizing device provided by an embodiment of the present application. The specific steps include:

[0100] Step S11: Obtain the user's current suction force.

[0101] Specifically, the atomizing device has a sensing element for detecting airflow changes, an airway communicating with the sensing element, and a control circuit connected to the sensing element. The sensing element is configured to detect the airflow changes in the airway, and the control circuit controls the atomizer to heat and atomize the matrix to be atomized or stop heating and atomizing the matrix to be atomized according to the airflow changes detected by the sensing element. The sensing element may be a frequency silicon microphone, a frequency microphone head, or a differential pressure sensor, which is used to detect the airflow or differential pressure changes in the atomizing device, so as to reflect the user's suction force. It can be understood that when the airway of the atomizing device is abnormal, such as blocked and / or leaking, although the user uses the same suction force, the change in the airflow in the airway will decrease. The sensing element detects the decrease in the airflow change in the airway, which may lead to a poor user suction experience and may even cause the atomizing device to malfunction seriously.

[0102] Step S12: Determine the airway state of the atomizing device according to the current suction force.

[0103] Specifically, the suction force of multiple users during multiple inhalations of the atomization device can be obtained through a large number of experiments in advance, and then the standard value can be calculated. For example, the average suction force can be used as the standard value. The standard value is pre-stored in the memory. When the user inhales the atomization device each time, the sensing element obtains the user's current suction force, and the control circuit determines and compares the current suction force with the pre-stored standard value. If the current suction force obtained by the sensing element is greater than or equal to the standard value, it indicates that there is no abnormality in the airway of the atomization device; if the current suction force obtained by the sensing element is less than or equal to the standard value, it indicates that there is an abnormality in the airway of the atomization device. To avoid errors, the user's current suction force can also be obtained continuously multiple times for multiple judgments. When the number of times the current suction force is less than the standard value is greater than a threshold, it is determined that the airway is abnormal.

[0104] Furthermore, multiple different standard value levels can also be set according to the range of the vital capacity of ordinary users, so that users can select an atomization device with an appropriate standard value according to their vital capacity.

[0105] Considering the differences in the vital capacity and suction habits of each user, there may be errors in pre-storing the standard value in advance. In another specific embodiment, the standard value is obtained by acquiring the suction force of the actual users of the atomization device. Specifically, the sensing element acquires multiple suction forces during the user's use process, such as five, ten, or fifteen. The control circuit calculates the average suction force of the multiple suction forces as the standard value, and when the user inhales the atomization device next time, it determines the magnitude relationship between the current suction force and the standard value. If the current suction force is greater than or equal to the standard value, it indicates that there is no abnormality in the airway of the atomization device; if the current suction force is less than the standard value, it indicates that there is an abnormality in the airway of the atomization device. It can be understood that by acquiring the suction force of the actual users of the atomization device to obtain the standard value, the judgment is more accurate.

[0106] See Figure 6 which is a schematic flow chart of the implementation method of steps S11 and S12 provided in an embodiment of the present application. Figure 5

[0107] Step S11: Obtain the user's current suction force, specifically including:

[0108] Step S110: Obtain the current frequency value generated based on the current suction force when the user inhales.

[0109] Specifically, the sensing element is a frequency-output sensing element. For example, it can be a frequency silicon microphone or a frequency microphone head. When the sensing element is working normally, it continuously outputs frequency values. When the user is not sucking, the frequency value generated by the sensing element is the initial frequency value. When the user uses the atomizing device, the sensing element obtains the user's current sucking force (negative pressure) and generates a corresponding current frequency value. Usually, one sucking action can last for 3 - 5 seconds. Therefore, during one sucking process, multiple frequency values are generated. As the sucking force increases, the frequency value increases, and as the sucking force decreases, the frequency value decreases. Additionally, the sensing element also has a trigger frequency value corresponding to the lowest sucking force for interrupt signal triggering. When the current sucking force is greater than the initial frequency value and less than the trigger frequency value, the atomizing device does not heat and atomize.

[0110] Step S12: Determine the airway state of the atomizing device according to the current sucking force, specifically including:

[0111] Step S120: Determine the airway state of the atomizing device according to the current frequency value.

[0112] Specifically, during the entire sucking process, the frequency value changes in real time. As the sucking force increases, the frequency value increases, and as the sucking force decreases, the frequency value decreases. Therefore, the control circuit can determine the airway state of the atomizing device according to the magnitude of the current frequency value.

[0113] See Figure 7 , which is a schematic flow chart of the airway detection method of the atomizing device provided by another embodiment of the present application. The difference from the method shown in Figure 5 is as follows:

[0114] Before step S11: Obtain the user's current sucking force, it further includes:

[0115] Step S101: When the atomizing device is sucked each time by the user, obtain a corresponding plurality of frequency values, and obtain the maximum frequency value among them. N sucking actions correspond to N maximum frequency values.

[0116] In an embodiment, when the user sucks the atomizing device each time, the control circuit is further configured to obtain a plurality of frequency values during the sucking process and obtain the maximum frequency value among them. It can be understood that N sucking actions correspond to N maximum frequency values.

[0117] Step S102: Obtain the average maximum frequency value based on the N maximum frequency values.

[0118] Specifically, the control circuit can calculate the average maximum frequency value based on multiple maximum frequency values. Thus, during the subsequent use of the atomization device by the user, if the maximum current frequency value of the current frequency values corresponding to the user's current suction force is greater than or equal to the average maximum frequency value, it is determined that there is no abnormality in the airway of the atomization device; if the maximum frequency value of the current frequency values corresponding to the user's current suction force is less than the average maximum frequency value, it is determined that there is an abnormality in the airway of the atomization device.

[0119] In one embodiment, the maximum current frequency value among the multiple current frequency values corresponding to the current suction force is the maximum frequency value among the frequency values corresponding to any suction force during any suction after N suctions. In another embodiment, the maximum current frequency value among the multiple current frequency values corresponding to the current suction force is the maximum frequency value among the frequency values corresponding to the next suction after N suctions. In yet another embodiment, the maximum current frequency value among the multiple current frequency values corresponding to the current suction force is the average value of M maximum frequency values among the frequency values corresponding to the next M (M>1) suction forces after N suctions.

[0120] See Figure 8 , which is a schematic flowchart of the implementation method of step S102 provided in an embodiment of the present application. Step S102: Obtain the average maximum frequency value based on N maximum frequency values, specifically including: Figure 7

[0121] Step S103: In response to the number of times of obtaining the maximum frequency value being greater than or equal to the second preset threshold, calculate the average maximum frequency value.

[0122] Specifically, the atomization device further includes a counter for recording the number of times of obtaining the maximum frequency value of the frequency value, and the control circuit is used to calculate the average maximum frequency value in response to the number of times of obtaining the maximum frequency value of the frequency value being greater than or equal to the second preset threshold. Among them, the value range of the second preset threshold can be 5-15. For example, the counter records the number of times of obtaining the maximum frequency value of the frequency value, and the control circuit calculates the average maximum frequency value in response to the number of times of obtaining the maximum frequency value of the frequency value being greater than or equal to 10 times.

[0123] See Figure 9 , which is a schematic flowchart of the implementation method of step S120 provided in an embodiment of the present application. Step S120: Determine the airway state of the atomization device according to the current frequency value, specifically including: Figure 6

[0124] Step S121: Compare the difference between the average maximum frequency value and the maximum current frequency value among the multiple current frequency values corresponding to the current suction force with the first preset threshold.

[0125] ​​Step S122: In response to the difference between the maximum frequency average value and the maximum current frequency value being greater than a first preset threshold, determine whether the airway of the atomization device is blocked / leaking.

[0126] Specifically, if the maximum frequency average value is less than or equal to the maximum current frequency value, it is determined that the airway of the atomization device is normal. For example, if the maximum current frequency value is 3200 Hz and the maximum frequency average value is 3000 Hz, it is determined that the airway of the atomization device is normal. If the maximum frequency average value is greater than the maximum current frequency value, and the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold, it is determined that the airway of the atomization device is abnormal. For example, the maximum current frequency value is 2800 Hz, the maximum frequency average value is 3000 Hz, and the first preset threshold is 100 Hz. That is, the difference between the maximum frequency average value and the maximum current frequency value is 200 Hz, and since the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold of 100 Hz, it is determined that the airway of the atomization device is abnormal.

[0127] See Figure 10 which is a schematic flowchart of the implementation method of step S122 provided in an embodiment of the present application. Step S122: In response to the difference between the maximum frequency average value and the maximum current frequency value being greater than a first preset threshold, determine whether the airway of the atomization device is blocked / leaking, specifically including: Figure 9

[0128] Step S1221: Obtain multiple maximum current frequency values.

[0129] Specifically, the control circuit can obtain the maximum current frequency value of multiple current frequency values based on the multiple current frequency values generated by the sensing element.

[0130] Step S1222: Compare the difference between the maximum frequency average value and each of the multiple maximum current frequency values with the first preset threshold.

[0131] Specifically, the control circuit is used to repeatedly compare the difference between the maximum frequency average value and the maximum current frequency value with the first preset threshold, and the counter is used to record the number of times the difference between the maximum frequency average value and the maximum current frequency value is compared with the first preset threshold.

[0132] Among them, the manner in which the control circuit repeatedly compares the difference between the maximum frequency average value and the maximum current frequency value with the first preset threshold can be to continuously and repeatedly compare the difference between the maximum frequency average value and the maximum current frequency value with the first preset threshold, or to compare the difference between the maximum frequency average value and the maximum current frequency value with the first preset threshold every n frequency values.

[0133] ​Among them, the first preset threshold can be a positive number or a negative number. Since whether it is blocked or leaking liquid is indicated by whether the frequency value increases or decreases, it can be set according to the characteristics of the customized sensing element. If the characteristic of the sensing element is that the suction force is positively correlated with the generated frequency value, the first preset threshold is a positive number; if the characteristic of the sensing element is that the suction force is negatively correlated with the generated frequency value, the first preset threshold is a negative number.

[0134] Step S1223: In response to the number of times that the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold being greater than the third preset threshold, determine that the airway of the atomizing device is blocked / leaking.

[0135] Specifically, the control circuit determines that the airway of the atomizing device is abnormal in response to the number of times that the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold being greater than the third preset threshold. For example, the third preset threshold is 10, and the control circuit determines that the airway of the atomizing device is abnormal in response to the number of times that the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold being greater than 10.

[0136] Among them, the comparison method in which the control circuit responds to the number of times that the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold being greater than the third preset threshold can be that the control circuit continuously responds to the number of times that the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold being greater than the third preset threshold. For example, the third preset threshold is 10, and the control circuit determines that the airway of the atomizing device is abnormal in response to the number of times that the difference between the maximum frequency average value and the maximum current frequency value is greater than the first preset threshold being greater than 10. If the number of times that the control circuit continuously responds to the difference between the maximum frequency average value and the maximum current frequency value being greater than the first preset threshold is 9, and the next maximum current frequency value is greater than the maximum frequency average value X, or the difference between the maximum frequency average value X and the maximum current frequency value is less than the first preset threshold, the counter starts counting again.

[0137] See Figure 11 , which is a schematic flow chart of the airway detection method of the atomizing device provided by another embodiment of the present application. The difference from the method shown in Figure 5 is that before step S11: obtaining the current suction force of the user, it further includes:

[0138] Step S104: Each time the atomizing device sucks, obtain a corresponding frequency value every second preset time interval. Obtain M frequency values during one suction, and generate a data list. N suctions correspond to N data lists.

[0139] Specifically, each time the user sucks on the atomizing device, the control circuit obtains a corresponding frequency value every second preset time interval. For example, the second preset time interval can be 0.2 s, 0.4 s, 0.6 s, etc. During one suction process, the control circuit 20 can obtain M frequency values and generate a data list for one suction. For N suctions, the control circuit can obtain N data lists and N * M frequency values.

[0140] Step S105: Based on the M frequency values corresponding to every second preset time interval in the N data lists, obtain the average frequency value. The N data lists correspond to M average frequency values.

[0141] Specifically, when the N suctions meet the fourth preset threshold, based on the M frequency values corresponding to every second preset time interval in the N data lists, obtain the average frequency value. The N data lists correspond to M average frequency values.

[0142] See Figure 12 which is the flowchart of the implementation method of step S105 provided by an embodiment of the present application. Step S105 specifically includes: Figure 11

[0143] Step S106: In response to the number of times of obtaining the data list being greater than or equal to the fourth preset threshold, calculate and obtain the average frequency value.

[0144] Specifically, the value range of the fourth preset threshold P is 5 - 15 times.

[0145] Figure 13 See Figure 6 which is the flowchart of the implementation method of step S120 provided by an embodiment of the present application. Step S120 specifically includes:

[0146]

[0147] Step S123: Compare the M average frequency values with the current data list generated by multiple current frequency values obtained at every second preset time interval of the current suction force.

[0148] Specifically, the current frequency value corresponding to 0.2 s in the current data list is compared with the first average frequency value in the average frequency values; the current frequency value corresponding to 0.4 s in the current data list is compared with the second average frequency value in the average frequency values; the current frequency value corresponding to 0.6 s in the current data list is compared with the third average frequency value in the average frequency values, and so on.

[0149] ​​​It can be understood that by sampling the aspiration force corresponding to multiple aspirations to obtain multiple frequency averages, M1 - M10 among the multiple frequency averages constitute the frequency change trend during one aspiration process. By comparing this frequency change trend with the current frequency values at corresponding times among the multiple current frequency values corresponding to the current aspiration force, the current airway state of the atomization device 300 can be determined more accurately.

[0150] See Figure 14 , which is provided by an embodiment of the present application Figure 13 The flowchart of the implementation method of step S124 in

[0151] Step S1241: Obtain multiple current data lists.

[0152] Among them, the current data list is similar to the method for obtaining the maximum current frequency value in the above text. The current data list can be a current data list generated from multiple current frequency values obtained at every second preset time interval corresponding to the aspiration force of any aspiration after N aspirations. The current data list can also be a current data list generated from multiple current frequency values obtained at every second preset time interval corresponding to the aspiration force of the next aspiration after N aspirations. Details are not elaborated here.

[0153] Step S1242: Compare the M frequency averages with the multiple current data lists respectively.

[0154] For example, take the M frequency averages obtained from the 1st - 10th aspirations, take the 11th aspiration as the current aspiration to obtain the current data list, and the control circuit compares the M frequency averages with the multiple current frequency values in the current data list; then take the M frequency averages obtained from the 2nd - 11th aspirations, take the 12th aspiration as the current aspiration to obtain the current data list, and the control circuit 20 compares the M frequency averages with the multiple current frequency values in the current data list; then take the M frequency averages obtained from the 3rd - 12th aspirations, take the 13th aspiration as the current aspiration to obtain the current data list, and the control circuit 20 compares the M frequency averages with the multiple current frequency values in the current data list.

[0155] Step S1243: In response to the number of times that all M frequency averages are greater than the corresponding current frequency values in the current data list being greater than or equal to the fifth preset threshold, determine that the airway of the atomization device is blocked / leaking liquid.

[0156] Specifically, the value range of the fifth preset threshold Q is 3 - 8 times.

[0157] See Figure 15 , which is the flowchart of the airway detection method of the atomization device provided by another embodiment of the present application. Figure 5The difference of the method shown is that before step S11: obtaining the current suction force of the user, it further includes:

[0158] Step S107: When the atomizing device performs each suction, obtain a corresponding plurality of frequency values according to a first preset time.

[0159] Specifically, the atomizing device regularly detects a plurality of frequency values F corresponding to each suction force according to the first preset time. For example, taking the first preset time as 0.2s and the time maintained for one suction as 4s, during one suction process, the atomizing device regularly detects 20 frequency values according to the first preset time.

[0160] See Figure 16 which is a schematic flow chart of the implementation method of step S120 provided by another embodiment of the present application. Step S120 specifically includes: Figure 6

[0161] Step S126: Compare the plurality of frequency values with the initial frequency value and the trigger frequency value respectively.

[0162] Specifically, the sensing element also has a trigger frequency value corresponding to the lowest suction force for triggering the interrupt signal and an initial frequency value generated when the user does not suck. Compare the plurality of frequency values corresponding to the suction force with the trigger frequency value and the initial frequency value one by one.

[0163] Step S127: In response to the plurality of frequency values being greater than the initial frequency value and less than the trigger frequency value, determine that the airway of the atomizing device is blocked / leaking liquid.

[0164] For example, when the user is currently sucking the atomizing device, the range of the plurality of current frequency values corresponding to the current suction force obtained by the atomizing device according to the first preset time is 450HZ - 550HZ, the trigger frequency value of the sensing element is 600HZ, and the initial frequency value is 400HZ. That is, the current frequency value is greater than the initial frequency value and less than the trigger frequency value, then it is determined that the airway of the atomizing device is abnormal and is completely blocked.

[0165] See Figure 17 which is a schematic flow chart of the airway detection method of the atomizing device provided by another embodiment of the present application. The difference from the method shown in Figure 5 is that before step S11: obtaining the current suction force of the user, it further includes:

[0166] Step S1: When the atomizing device performs each suction, obtain a corresponding plurality of statistical suction forces and obtain the maximum statistical suction force among them. N suctions correspond to N maximum statistical suction forces.

[0167] ​For example, during the use of the atomization device, the sensing element can detect multiple statistical suction forces generated by each suction, and the control circuit obtains the maximum statistical suction force among the multiple statistical suction forces. N suctions correspond to N maximum statistical suction forces, thereby obtaining multiple maximum statistical suction forces.

[0168] In a specific embodiment, the control circuit obtaining the corresponding multiple statistical suction forces specifically means obtaining the frequency value or pressure difference value generated by the sensing element based on the statistical suction force.

[0169] Step S2: Obtain the average value of the maximum statistical suction forces based on the N maximum statistical suction forces.

[0170] Specifically, the control circuit calculates the average value of the maximum statistical suction forces based on the obtained N maximum statistical suction forces.

[0171] Among them, step S12: Determine the airway state of the atomization device according to the current suction force, specifically including:

[0172] Step S1201: Compare the difference between the average value of the maximum statistical suction forces and the maximum current statistical suction force among the multiple current statistical suction forces corresponding to the current suction force with a first preset threshold.

[0173] Among them, in a specific embodiment, the current suction force can be multiple current frequency values or current pressure difference values obtained by the sensing element based on the current suction force.

[0174] Step S1202: In response to the difference between the average value of the maximum statistical suction forces and the maximum current statistical suction force being greater than the first preset threshold, determine that the airway of the atomization device is blocked / leaking liquid.

[0175] Specifically, if the average value of the maximum statistical suction forces is less than or equal to the maximum current statistical suction force, it is determined that there is no abnormality in the airway of the atomization device. If the average value of the maximum statistical suction forces is greater than the maximum current statistical suction force, and the difference between the average value of the maximum statistical suction forces and the maximum current statistical suction force is greater than the first preset threshold, it is determined that the airway of the atomization device is abnormal. For example, if the maximum current statistical suction force is 400, the average value of the maximum statistical suction forces is 600, and the first preset threshold is 100, that is, the difference between the average value of the maximum statistical suction forces and the maximum current statistical suction force is 200, and the difference between the average value of the maximum statistical suction forces and the maximum current statistical suction force is greater than the first preset threshold, it is determined that the airway of the atomization device is abnormal.

[0176] See Figure 18 , which is a schematic flowchart of the airway detection method of the atomization device provided by another embodiment of the present application, and Figure 5The difference of the method shown is that in step S12: determining the airway state of the atomization device according to the current suction force, and then further including:

[0177] Step S13: when the airway of the atomization device is blocked and / or leaking liquid, sending a feedback signal.

[0178] Specifically, when the airway of the atomization device is abnormal, the control circuit sends a feedback signal to remind the user that the airway of the atomization device is blocked and / or leaking liquid and needs to be processed. Among them, the feedback signal can be a prompt sound, an indicator light, etc.
