Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0060] Please see Figure 1 , Figure 1 This is a flowchart of a cigarette cartridge detection method provided in an embodiment of the present invention, such as... Figure 1 As shown, the method for detecting cigarette cartridges includes the following steps:

[0061] 101. When the tobacco cartridge is in the heating state, acquire the current signal sequence of the tobacco device.

[0062] In this embodiment of the invention, the aforementioned tobacco cartridge is a tobacco cartridge inserted into a smoking device, and the aforementioned smoking device is an electronic smoking device using electromagnetic induction heating.

[0063] When no tobacco cartridge is inserted, the smoking device is in an unloaded state. When a tobacco cartridge is inserted, the device is in a loaded state. When the tobacco cartridge is in a heated state, the device is in a loaded state. When the device is in a loaded state, the tobacco cartridge absorbs energy, causing the load current to be greater than the unloaded current.

[0064] The above current signal sequence can be understood as monitoring the current signal of the smoking device in the time dimension under the working condition of the smoking device, and obtaining a continuous current signal in the time dimension as the current signal sequence.

[0065] 102. Perform feature extraction on the current signal sequence to obtain the time-series features corresponding to the current signal sequence.

[0066] In this embodiment of the invention, feature extraction can be performed on the current signal sequence to extract the features implicit between the current signal and time. The features implicit between the current signal and time can be used to describe the characteristics of the e-cigarette cartridge.

[0067] 103. Based on temporal characteristics, perform matching detection on e-cigarette cartridges and e-cigarette devices.

[0068] In this embodiment of the invention, the aforementioned timing features include the features implied between the current signal and time. By analyzing the aforementioned timing features, the features of the tobacco cartridge can be obtained, and the matching of the tobacco cartridge and the smoking device can be detected based on the features of the tobacco cartridge.

[0069] It should be noted that the no-load power consumption of the smoking device is relatively low, and the reasonable no-load current is usually between 0.5 and 0.8A. The current required for the matching e-liquid cartridge to absorb energy is between 1 and 2.5A. Foreign objects such as iron bars will absorb a large current, causing the smoking device to be overloaded and damaged. The current absorbed by mismatched e-liquid cartridges and authorized e-liquid cartridges at different times has its own characteristics.

[0070] In this embodiment of the invention, when the tobacco cartridge is in a heated state, the current signal sequence of the smoking device is acquired; feature extraction is performed on the current signal sequence to obtain the corresponding time-series features; based on the time-series features, the matching of the tobacco cartridge and the smoking device is detected. By acquiring the current signal sequence of the smoking device when the tobacco cartridge is in a heated state and extracting the corresponding time-series features, and utilizing the characteristics between the load current and time of the smoking device, the matching between the tobacco cartridge and the smoking device can be detected. This allows for the detection of mismatched tobacco cartridges, thereby preventing the insertion of incompatible tobacco cartridges into the smoking device and improving the safety of the smoking device and tobacco cartridge during use.

[0071] Optionally, in the step of detecting the compatibility between the tobacco cartridge and the smoking device based on time-series features, the following steps can be taken: obtaining the current signal sequence of the smoking device when it is loaded with the authorized tobacco cartridge; extracting features from the current signal sequence of the smoking device when it is loaded with the authorized tobacco cartridge to obtain the corresponding adaptation time-series features; comparing the time-series features with the adaptation time-series features; if the comparison is successful, the compatibility detection between the tobacco cartridge and the smoking device is passed; if the comparison fails, the compatibility detection between the tobacco cartridge and the smoking device is failed.

[0072] In this embodiment of the invention, the current signal sequence of the smoking device when loaded with an authorized tobacco cartridge can be obtained in advance. Then, feature extraction is performed on the current signal sequence to obtain the adaptation timing features of the authorized tobacco cartridge. The timing features of the tobacco cartridge are compared with the adaptation timing features of the authorized tobacco cartridge. If the similarity is greater than a preset similarity threshold, the tobacco cartridge is considered authorized; if the similarity is less than the preset similarity threshold, the tobacco cartridge is considered unauthorized. When the tobacco cartridge is authorized, the matching detection between the tobacco cartridge and the smoking device passes; when the tobacco cartridge is unauthorized, the matching detection fails.

[0073] It should be noted that, since the heating element in the e-cigarette cartridge is made of a synthetic material that mainly contains iron, different types of e-cigarette cartridges will exhibit different heating characteristics due to differences in material formulation, size, shape and other parameters. These differences can be reflected by the implicit characteristics between the current signal and time.

[0074] Optionally, before acquiring the current signal sequence of the smoking device, the current signal of the smoking device can be acquired periodically; based on the current signal, it can be detected whether the smoking device is in an unloaded state or a foreign object inserted state; if the smoking device is not in an unloaded state and is not in a foreign object inserted state, the current signal sequence of the smoking device can be acquired when the tobacco cartridge is in a heating state.

[0075] In this embodiment of the invention, energy can be output once every time period T, with each energy output lasting for time t. During this time, the generated current signal is measured, such as... Figure 2 As shown.

[0076] The no-load power consumption of the smoking device is relatively low, with a typical reasonable no-load current between 0.5 and 0.8 A. The current required for the matching cartridge to absorb energy is between 1 and 2.5 A. Foreign objects, such as iron bars, will absorb a large current. If the measured current signal is the no-load current, it indicates that the smoking device is in an no-load state. If the measured current signal is the load current, it indicates that the smoking device is in a load state. If the measured current signal is greater than the load current, it indicates that the smoking device is in a foreign object insertion state.

[0077] The current signal of the smoking device can be continuously measured when the device is under load to obtain the current signal sequence of the device when the cartridge is in the heating state.

[0078] In this embodiment of the invention, the idling and foreign object insertion of the smoking device can be identified through periodic energy output, thereby controlling the ignition timing, preventing dry burning, and preventing foreign objects from damaging the smoking device.

[0079] It should be noted that the cartridge detection method provided in this embodiment of the invention can be applied to electronic cigarettes, electronic atomizers and other devices that can perform cartridge detection.

[0080] Optional, please see Figure 3 , Figure 3 This is a flowchart of a smoking device control method provided in an embodiment of the present invention, such as... Figure 3 As shown, the smoking device control method includes the following steps:

[0081] 301. When the tobacco cartridge is in the heating state, acquire the current signal sequence of the tobacco device.

[0082] In this embodiment of the invention, the aforementioned tobacco cartridge is a tobacco cartridge inserted into a smoking device, and the aforementioned smoking device is an electronic smoking device using electromagnetic induction heating.

[0083] When no tobacco cartridge is inserted, the smoking device is in an unloaded state. When a tobacco cartridge is inserted, the device is in a loaded state. When the tobacco cartridge is in a heated state, the device is in a loaded state. When the device is in a loaded state, the tobacco cartridge absorbs energy, causing the load current to be greater than the unloaded current.

[0084] The above current signal sequence can be understood as monitoring the current signal of the smoking device in the time dimension under the working condition of the smoking device, and obtaining a continuous current signal in the time dimension as the current signal sequence.

[0085] 302. Perform feature extraction on the current signal sequence to obtain the time-series features corresponding to the current signal sequence.

[0086] In this embodiment of the invention, feature extraction can be performed on the current signal sequence to extract the features implicit between the current signal and time. The features implicit between the current signal and time can be used to describe the characteristics of the e-cigarette cartridge.

[0087] 303. Based on time-series characteristics, perform matching detection on e-cigarette cartridges and e-cigarette devices.

[0088] In this embodiment of the invention, the aforementioned timing features include the features implied between the current signal and time. By analyzing the aforementioned timing features, the features of the tobacco cartridge can be obtained, and the matching of the tobacco cartridge and the smoking device can be detected based on the features of the tobacco cartridge.

[0089] It should be noted that the no-load power consumption of the smoking device is relatively low, and the reasonable no-load current is usually between 0.5 and 0.8A. The current required for the matching e-liquid cartridge to absorb energy is between 1 and 2.5A. Foreign objects such as iron bars will absorb a large current, causing the smoking device to be overloaded and damaged. The current absorbed by mismatched e-liquid cartridges and authorized e-liquid cartridges at different times has its own characteristics.

[0090] In this embodiment of the invention, when the tobacco cartridge is in a heating state, the current signal sequence of the smoking device is acquired; features are extracted from the current signal sequence to obtain the corresponding timing features; based on the timing features, a matching detection is performed between the tobacco cartridge and the smoking device; when the matching between the tobacco cartridge and the smoking device is successful, the heating state of the tobacco cartridge is maintained; when the matching between the tobacco cartridge and the smoking device fails, the heating state of the tobacco cartridge is disconnected. By acquiring the current signal sequence of the smoking device while the tobacco cartridge is in a heating state and extracting the timing features corresponding to the current signal sequence, and utilizing the characteristics between the load current and time of the smoking device, the matching between the tobacco cartridge and the smoking device can be detected. This allows for the detection of mismatched tobacco cartridges, thereby preventing the insertion of mismatched tobacco cartridges into the smoking device and improving the safety of the smoking device and tobacco cartridge during use.

[0091] 304. When the compatibility between the tobacco cartridge and the smoking device is satisfactory, the tobacco cartridge will continue to be heated.

[0092] In this embodiment of the invention, when the compatibility between the tobacco cartridge and the smoking device is passed, it indicates that the tobacco cartridge is an authorized tobacco cartridge, and the power output of the electromagnetic heating device can be controlled according to the normal heating procedure so that the smoking device maintains the heating state of the tobacco cartridge. The normal heating procedure is the heating procedure of the authorized tobacco cartridge.

[0093] 305. If the compatibility between the tobacco cartridge and the smoking device fails, the heating of the tobacco cartridge will be disconnected.

[0094] In this embodiment of the invention, when the compatibility between the tobacco cartridge and the smoking device fails, it indicates that the tobacco cartridge is an unauthorized tobacco cartridge. The electromagnetic heating device can be controlled to stop power output, so that the smoking device stops heating the unauthorized tobacco cartridge, thereby protecting the smoking device and improving its safety.

[0095] Optionally, in the step of detecting the compatibility between the tobacco cartridge and the smoking device based on time-series features, the following steps can be taken: obtaining the current signal sequence of the smoking device when it is loaded with the authorized tobacco cartridge; extracting features from the current signal sequence of the smoking device when it is loaded with the authorized tobacco cartridge to obtain the adaptation time-series features corresponding to the current signal sequence of the smoking device when it is loaded with the authorized tobacco cartridge; comparing the time-series features with the adaptation time-series features; if the comparison is successful, the compatibility detection between the tobacco cartridge and the smoking device is passed; if the comparison fails, the compatibility detection between the tobacco cartridge and the smoking device is failed.

[0096] In this embodiment of the invention, the current signal sequence of the smoking device when loaded with an authorized tobacco cartridge can be obtained in advance. Then, feature extraction is performed on the current signal sequence to obtain the adaptation timing features of the authorized tobacco cartridge. The timing features of the tobacco cartridge are compared with the adaptation timing features of the authorized tobacco cartridge. If the similarity is greater than a preset similarity threshold, the tobacco cartridge is considered authorized; if the similarity is less than the preset similarity threshold, the tobacco cartridge is considered unauthorized. When the tobacco cartridge is authorized, the matching detection between the tobacco cartridge and the smoking device passes; when the tobacco cartridge is unauthorized, the matching detection fails.

[0097] It should be noted that, since the heating element in the e-cigarette cartridge is made of a synthetic material that mainly contains iron, different types of e-cigarette cartridges will exhibit different heating characteristics due to differences in material formulation, size, shape and other parameters. These differences can be reflected by the implicit characteristics between the current signal and time.

[0098] Optionally, before acquiring the current signal sequence of the smoking device, the current signal of the smoking device can be acquired periodically; based on the current signal, it can be detected whether the smoking device is in an unloaded state or a foreign object inserted state; if the smoking device is in an unloaded state, the current signal of the smoking device can continue to be acquired periodically; if the smoking device is in a foreign object inserted state, the smoking device can be controlled to turn off and an alarm can be issued; if the smoking device is neither in an unloaded state nor in a foreign object inserted state, the current signal sequence of the smoking device can be acquired when the tobacco cartridge is in a heating state.

[0099] In this embodiment of the invention, energy can be output once every time period T, with each energy output lasting for time t. During this time, the generated current signal is measured, such as... Figure 2 As shown.

[0100] The no-load power consumption of the smoking device is relatively low, with a typical reasonable no-load current between 0.5 and 0.8 A. The current required for the matching cartridge to absorb energy is between 1 and 2.5 A. Foreign objects, such as iron bars, will absorb a large current. If the measured current signal is the no-load current, it indicates that the smoking device is in an no-load state. If the measured current signal is the load current, it indicates that the smoking device is in a load state. If the measured current signal is greater than the load current, it indicates that the smoking device is in a foreign object insertion state.

[0101] The current signal of the smoking device can be continuously measured when the device is under load to obtain the current signal sequence of the device when the cartridge is in the heating state.

[0102] In this embodiment of the invention, the idling and foreign object insertion of the smoking device can be identified through periodic energy output, thereby controlling the ignition timing, preventing dry burning, and preventing foreign objects from damaging the smoking device.

[0103] Optional, please see Figure 4 , Figure 4 This is a flowchart of another smoking device control method provided in an embodiment of the present invention, including:

[0104] The controller controls the electromagnetic heating device to output energy once every time interval T (preferably 1 second), with each output time t (preferably 50 milliseconds), during which the generated current is measured.

[0105] First, determine whether the smoking device is unloaded based on the current. If it is unloaded, wait for time T, and then the controller controls the electromagnetic heating device to output energy once.

[0106] The current is used to determine whether the smoking device is under a reasonable load. A reasonable load includes a reasonable cartridge current. An unreasonable load is a large current or overload that exceeds the normal range. The reasonable cartridge current is the current of the authorized cartridge, and the current of the authorized cartridge meets the characteristics of the authorized cartridge.

[0107] If the measured current is no-load current, repeat the measurement after a waiting time T. A no-load current indicates that no tobacco cartridge or foreign object is inserted into the device. Continue to control the electromagnetic heating device to output energy once every time T (preferably 1 second), with each output lasting t (preferably 50 milliseconds), and measure the current generated during this period.

[0108] If the measured current of the cartridge is reasonable, maintain the heating state and monitor the relationship between current change and time. If it meets the characteristics of an authorized cartridge, control the power output according to the normal heating procedure. Otherwise, cut off the power to protect the device and continue to control the electromagnetic heating device to output energy once every time T (preferably 1 second), with each output time t (preferably 50 milliseconds), during which the generated current is measured.

[0109] During normal heating, if the output current is measured to become an open-circuit current, it is determined that the cigarette cartridge has been removed, and the electromagnetic heating device continues to output energy once every time interval T (preferably 1 second), with each output time t (preferably 50 milliseconds), during which the generated current is measured.

[0110] If a large current exceeding the normal range is measured, it is determined that a foreign object has entered. The power supply should be turned off and a shutdown alarm should be triggered to protect the appliance.

[0111] In this embodiment of the invention, the timing features corresponding to the current signal sequence can be extracted by acquiring the current signal sequence of the smoking device when the tobacco cartridge is in the heating state. By utilizing the characteristics between the load current and time of the smoking device, the matching between the tobacco cartridge and the smoking device can be detected. Incompatible tobacco cartridges can be detected, thereby preventing incompatible tobacco cartridges from being inserted into the smoking device and improving the safety of the smoking device and tobacco cartridges during use.
