[0025] In order to make the technical problems, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to explain the present application and not to limit the present application.

[0026] In the aerosol generating device, the aerosol generating substrate (hereinafter referred to as substrate) needs to be heated to generate aerosol for smoking. Therefore, in the aerosol generating device, a heating area for the substrate is provided, and the substrate is carried on a substrate tape.

[0027] For example, the substrate tape includes a substrate and a substrate provided on the substrate, and the substrate is a material that can be heated by electromagnetic induction, or the substrate is provided with a material that can be heated by electromagnetic induction, such as aluminum foil or other metal. The substrate tape is continuously transported to the heating area, so that the substrate on the substrate tape is atomized.

[0028] When the aerosol generating device is used, the transmission device of the substrate tape can also be referred to as the switching device of the substrate tape, which is used to change the relative position of the substrate tape and the heating area. If the transmission device of the substrate tape fails, the output of the substrate tape may fail. The output failure of the substrate tape can cause the heating area to fail to effectively heat the substrate or repeatedly heat the substrate that has been heated. Therefore, the present application provides a method for processing information about output of a substrate tape of an aerosol generating device, which detects whether the output of the substrate tape fails or is normal, so as to take effective measures in time in case of output failure of the substrate tape.

[0029] As shown in Fig. 1, in an example of the present application, the method for processing information about output of a substrate tape of an aerosol generating device includes the following steps S11 to S13.

[0030] Step S11: obtaining smoking information.

[0031] In the example of the present application, the smoking information can be information generated when a user smokes the aerosol generating device.

[0032] When step S11 is performed, the aerosol generating device enters a working state. The aerosol generating device can heat the substrate strip by resistance, microwave, light wave, electromagnetic or other methods. The electromagnetic heating method is described in detail below: when the user inhales, the pneumatic inductive switch (for example, a microphone) sends a signal to the controller under the action of the airflow of the inhalation, and the controller controls the heating assembly to heat. The heating assembly heats the substrate, so that the substrate carried by the substrate strip is heated to a temperature at which an aerosol is generated, for the user to inhale.

[0033] In the embodiments of the present application, the substrate is in a solid state, and the substrate is carried on an aluminum foil. Exemplarily, the substrate strip of the aerosol generating device can be any suitable heat-not-burn substrate, such as tobacco sheet, herbal mixture, etc.

[0034] With continuous heating of the substrate, the substrate strip needs to move positions so that unheated substrate is input into the heating area, and the heated substrate strip is output from the heating area. The relative positions between the substrate strip and the heating area are automatically adjusted by the aerosol generating device, for example, when the user inhales, the motor of the aerosol generating device rotates to drive the movement of the strip-shaped substrate strip, so that the strip-shaped substrate strip with new substrate is fed into the heating area, and after the inhalation is completed, the strip-shaped substrate strip that has been heated is moved out of the heating area.

[0035] Step S12: in response to the inhalation information, a first electric signal of the motor is obtained; the motor is used to drive the output of the substrate strip of the aerosol generating device; and the first electric signal is generated when the motor is driven based on the inhalation information.

[0036] In the embodiments, the motor is a stepper motor, which is an inductive motor that converts an electric pulse signal into mechanical angular displacement or linear displacement. The driving chip (integrated chip, IC) of the stepper motor can send a pulse signal at a set frequency, and the stepper motor drives the rotation of the shaft according to the received pulse signal. The shaft drives the movement of the strip-shaped substrate strip or the cartridge cabin fixed to the shaft, and outputs the substrate strip.

[0037] The first electric signal of the stepper motor can be an electric signal generated in the external circuit of the stepper motor. For example, a first circuit is arranged outside the shaft of the stepper motor, and the first circuit generates electric signals of different sizes with the rotation of the stepper motor.

[0038] The first electric signal of the stepper motor can also be an electric signal generated in the internal circuit of the stepper motor. For example, a second circuit is arranged inside the stepper motor, and the second circuit generates electric signals of different sizes with the rotation of the stepper motor. The internal circuit of the stepper motor can include a coil, a rotor, etc.

[0039] In the embodiments of the present application, the suction information can be used to trigger the step S12 described above, and can also be used to trigger the rotation of the stepping motor. Whether the stepping motor rotates successfully or not, it does not affect the execution of the step S12 triggered by the suction information.

[0040] The step S13: determining the output state of the substrate tape according to the first electric signal.

[0041] The step of determining the output state of the substrate tape according to the first signal can include: determining whether the substrate tape is normally output according to the size of the first electric signal.

[0042] The output state of the substrate tape can be a transmission state of the substrate tape in the process of being transmitted. The classification of the output state of the substrate tape can be set arbitrarily according to actual needs. In a possible implementation, the output state of the substrate tape can include: normal and abnormal. The output state of the substrate tape can at least include a normal output state indicating that the transmission of the substrate tape is normal and an abnormal output state indicating that the transmission of the substrate tape is abnormal.

[0043] In another example, the abnormal output state can be further subdivided according to the category of the abnormality. For example, the abnormal output state can further include any one or more of the following cases.

[0044] Case one: the output of the substrate tape is abnormal because the motor stops rotating due to motor failure.

[0045] Case two: the output of the substrate tape is abnormal because the transmission of the substrate tape is blocked and stuck.

[0046] In the embodiments of the present application, the stuck can also be referred to as the tape stuck. In the case of the stuck, the motor cannot drive the reel to rotate due to the increase of the load, and in this case, the signal output by the sensor can not change.

[0047] Case three: the output of the substrate tape is abnormal because the substrate tape is disconnected (or can be referred to as broken or broken tape), so that the stepping motor has no load.

[0048] The disconnection of the substrate can also be caused by the broken tape of the substrate tape. In this case, the originally continuous substrate tape is in a disconnected state, and at this time, the reel is idling, and the signal output by the sensor usually does not show regular periodic changes.

[0049] Case four: the output of the substrate tape is abnormal because the substrate is exhausted, so that the motor cannot continue to drive the substrate tape to output the substrate.

[0050] Case five: the output of the substrate tape is abnormal because of abnormal speed. That is, although the sensor output signal changes regularly, the regular change does not conform to the preset rule.

[0051] In another implementation, determining the output state of the substrate strip according to the first signal can include: performing calculation on the first signal to obtain a calculation result, and determining the output state of the substrate strip according to the calculation result.

[0052] In the embodiments of the present application, the electrical signal of the stepping motor used to drive the output of the substrate strip can be obtained in the case of heating the substrate strip in the aerosol generating device, and the output state of the substrate strip can be determined according to the electrical signal of the stepping motor, so as to help the user to monitor the abnormal condition in time when the substrate strip is abnormally output.

[0053] In one implementation, the first electrical signal is a first frequency signal of the pulse signal of the stepping motor, and determining the output state of the substrate strip according to the first electrical signal includes: determining that the output state of the substrate strip is stopped due to disconnection when the first electrical signal indicates that the rotating speed of the stepping motor exceeds a first preset threshold value; and determining that the output state of the substrate strip is abnormal due to jamming when the electrical signal indicates that the rotating speed of the stepping motor is less than a second preset threshold value, the second preset threshold value being less than the first preset threshold value.

[0054] In the embodiments, the pulse signal of the stepping motor can be a pulse signal used to drive the rotation of the stepping motor. The pulse signal can be a signal with discontinuous waveform in the Y-axis direction of the plane coordinate system.

[0055] In another possible implementation, the pulse signal of the stepping motor can be a pulse signal converted from the rotation of the rotating shaft of the stepping motor.

[0056] In one implementation, the first frequency information of the pulse signal of the stepping motor is frequency information of the pulse signal generated by the driving chip of the stepping motor, and the substrate strip output information processing of the aerosol generating device further includes: obtaining a second electrical signal of the internal circuit of the stepping motor; sending a level signal used to adjust the pulse to the driving chip of the stepping motor according to the second electrical signal; and adjusting the sending frequency of the pulse signal according to the level signal.

[0057] In the embodiments, the second electrical signal in the stepping motor can be one of the feedback signals of the control system of the stepping motor, and in other possible implementations, other types of signals can also be used as the feedback signals of the control system of the aerosol generating device.

[0058] In the case of jamming or idling of the stepping motor, the current in the stepping motor can change, and by obtaining the feedback signal of the current in the stepping motor, the controller used to control the stepping motor can adjust the rotating speed of the stepping motor so as to adapt the rotating speed of the stepping motor to the load of the stepping motor.

[0059] In an embodiment, the second circuit signal comprises a coil current inside the stepper motor.

[0060] In an embodiment, the level signal is used to reduce the transmission frequency of the pulse signal when the coil current increases, and to increase the transmission frequency of the pulse signal when the coil current decreases.

[0061] In this embodiment, when the coil current inside the stepper motor increases, it indicates that the stepper motor may be stalled (stopping due to jamming), at which time the transmission frequency of the pulse signal can be reduced. When the stepper motor is idling, the current consumption of the motor will be relatively low due to zero load, and at this time, in order to distinguish between the cases of stalling and idling, the controller in the internal control system of the aerosol-generating device can control the driving chip to increase the transmission frequency of the pulse signal used to control the stepper motor. The rotation state of the stepper motor can be determined by the pulse signal generated by the driving chip, and the output state of the substrate strip can be determined accordingly.

[0062] In an embodiment, determining the output state of the substrate strip according to the first electrical signal comprises: determining the rotation speed of the stepper motor according to the first frequency information; and determining the output state of the substrate strip according to the rotation speed of the stepper motor.

[0063] In a possible implementation, if the rotation speed of the stepper motor is higher than a first rotation speed threshold, it is considered that the output state of the substrate strip is abnormal due to a broken strip. If the rotation speed of the stepper motor is lower than a second rotation speed threshold, it is considered that the output state of the substrate strip is abnormal due to jamming.

[0064] In an embodiment, the substrate strip output information processing method of the aerosol-generating device further comprises: obtaining a pulse signal of an encoder; the encoder comprises an optical encoder disk and a detector; the optical encoder disk is connected to the rotating shaft of the stepper motor, and the pulse signal is generated by the detector reading the change of the scale signal of the optical encoder disk; determining the rotation speed of the stepper motor according to the pulse signal; and the rotation speed of the stepper motor is used to determine the output state of the substrate strip.

[0065] In a possible implementation, the encoder can be a device that converts mechanical motion into an electrical signal, which can be installed on the rotating shaft of the stepper motor. As the rotating shaft of the stepper motor rotates, the encoder will output a series of pulse signals, and the number and frequency of these pulse signals are directly proportional to the rotation speed of the stepper motor. Therefore, by measuring the pulse signals output by the encoder, the rotation speed of the motor can be calculated.

[0066] In a possible implementation, determining the rotation speed of the stepper motor according to the pulse signal can comprise: determining the range of the rotation speed of the stepper motor according to the pulse signal, or calculating the rotation speed value of the stepper motor according to the pulse signal.

[0067] In the case of determining the range of the rotation speed of the stepper motor according to the pulse signal, the occurrence time of the pulse signal of the set frequency can be determined by the encoder, and the range of the rotation speed of the stepper motor can be determined according to the occurrence time or time interval of the pulse signal of the set frequency.

[0068] For example, the occurrence time of the pulse signal of the set high frequency can be determined by the encoder, and the detector detects the rotation speed of the photoelectric encoder disc corresponding to the frequency of the pulse signal generated by the detector. When the frequency of the pulse signal is higher than the preset frequency of the pulse signal of the high frequency, the rotation speed of the stepper motor is higher than the rotation speed value corresponding to the pulse signal of the high frequency.

[0069] For another example, the occurrence time of the pulse signal of the set low frequency can be determined by the encoder, and when the frequency of the pulse signal is lower than the preset frequency of the pulse signal of the low frequency, the rotation speed of the stepper motor is lower than the rotation speed value corresponding to the pulse signal of the low frequency.

[0070] In the case of calculating the rotation speed value of the stepper motor according to the pulse signal, the real-time rotation speed of the photoelectric encoder disc can be detected by the detector, and the pulse signal corresponding to the rotation speed can be generated.

[0071] In another possible implementation, the rotation speed of the stepper motor can be detected by using a speed sensor.

[0072] In another possible implementation, the rotation speed of the rotation shaft of the substrate strip can be detected by using the encoder or the speed sensor, and the output state of the substrate strip can be determined by comparing the rotation speed of the rotation shaft of the substrate strip with the rotation speed of the stepper motor.

[0073] For example, the substrate strip is an aluminum foil. The aluminum foil is placed in a container shaped like a magnetic tape cassette and is fixed in the form of a conveyor belt. Referring to FIG. 2. The substrate strip can be output to a target area (which can also be referred to as a heating area) as the motor of the aerosol generating device rotates. The target area can be a heating area to which the heating device is directed. For example, the heat-not-burn substrate strip can be a reel-wound sheet-type substrate strip. In the example shown in FIG. 2, as shown in FIG. 2, the housing of the aerosol generating device includes a first storage space 21a and a second storage space 21b. The first storage space 21a is used to store fresh substrate strips (i.e., substrate strips carrying unheated substrate), and the second storage space 21b is used to store residual substrate strips. Among them, the residual substrate strip can not carry the substrate or carry the residue after the substrate is heated.

[0074] The first storage space 21a is provided with a first reel 22a at the center, and the second storage space 21b is provided with a second reel 22b at the center. The first reel 22a is used to wind the substrate strip carrying the substrate, and the second reel 22b is used to wind the residual substrate strip. In a good use state of the aerosol generating device, the substrate strips on the two reels are connected together to form a transmission substrate strip. The motor of the aerosol generating device can be used to directly or indirectly drive the two reels to rotate in an operating state. For example, at least in the case of obtaining the puffing information, the motor of the aerosol generating device is operated to drive the reels to rotate, and the fresh substrate can be moved to the heating area 24 under the carrying of the substrate strip. The heating device located in the heating area 24 heats the substrate. If the user continues to puff, the motor drives the reels to continue to rotate, and the heated residual substrate strip leaves the heating area 24 and is wound onto the second reel 22b. The new substrate strip released from the first reel 22a continues to move to the heating area 24. In this way, as the user continues to puff, the substrate strip is continuously moved to the heating area 24, and the substrate strip in the heating area 24 is continuously replaced, so that there is always substrate on the substrate strip in the heating area 24 under the heating of the heating device.

[0075] On the basis of the example shown in FIG. 2, the rotation of the stepping motor drives the transmission belt to rotate, and the frequency corresponding to the rotation speed of the stepping motor can be collected by the encoder each time. The MCU of the aerosol generating device can compare the collected frequency with the pre-set frequency reference value. If the threshold value is exceeded, it is judged as a product failure, and the user needs to be reminded by light or vibration. In the aerosol generating device, a first encoder and a second encoder can be provided, wherein the first encoder can be used to detect the rotation speed of the rotation shaft of the stepping motor, and the second encoder can be used to detect the actual rotation speed of the substrate strip reel. Then, the MCU of the aerosol generating device can calculate the theoretical rotation speed of the substrate strip reel according to the rotation speed of the rotation shaft of the stepping motor, compare the theoretical rotation speed with the actual rotation speed, and determine the output state of the substrate strip according to the comparison result.

[0076] In an embodiment, the first frequency information of the pulse signal of the stepping motor is the information of the pre-set reference frequency of the stepping motor; and the output state of the substrate strip is determined according to the rotation speed and the electrical signal, including: the second frequency information of the rotation of the stepping motor is determined according to the rotation speed; and the output state of the substrate strip is determined according to the relative size comparison result of the first frequency information and the second frequency information.

[0077] In an example, the frequency f of the collected pulse signal is sent to the micro control unit (MCU) of the aerosol generating device, and the normal working frequency f1±10% (i.e. the frequency reference value in the foregoing embodiment) is pre-set in the MCU. If f>f1±10%, it is judged as a broken strip or idling, and if f<f1±10%, it is judged as a jam.

[0078] In another example, when determining the output state of the substrate tape according to the electrical signal, the MCU can further determine the frequency variation of the pulse signal according to the received frequency f, calculate the variation information of the rotation speed of the stepper motor according to the frequency variation, and then determine the output state of the substrate tape according to the variation information.

[0079] If the speed variation information of the stepper motor indicates that the rotation speed of the rotation shaft of the stepper motor decreases, that is, the speed of the stepper motor is detected to slow down, it is determined that the output state of the substrate tape is stuck due to an increase in load, or in other words, it is determined that the output state of the substrate tape is abnormal due to the sticking.

[0080] If the speed variation information of the stepper motor indicates that the rotation speed of the rotation shaft of the stepper motor increases, that is, the speed of the stepper motor is detected to speed up, it is determined that the output state of the substrate tape is a broken tape or idling due to a decrease in load, or in other words, it is determined that the output state of the substrate tape is abnormal due to the broken tape.

[0081] If the speed variation information of the stepper motor indicates that the rotation speed of the rotation shaft of the stepper motor approaches to stop (approaches to 0 speed): that is, the pulse signal is detected to completely stop, it is determined that the output state of the substrate tape is that the motor stops rotating, or in other words, it is determined that the output state of the substrate tape is abnormal due to the sticking.

[0082] In an embodiment, the electrical signal includes the coil current of the stepper motor; and determining the output state of the substrate tape according to the electrical signal includes: in the case of an increase in the coil current, determining that the output state of the substrate tape is abnormal due to the sticking; and in the case of a decrease in the coil current, determining that the output state of the substrate tape is abnormal due to the broken tape.

[0083] For example, a current detection device can be arranged inside or outside the stepper motor to detect the coil current of the stepper motor.

[0084] In an example of the present application, if the two ends of the substrate tape are fixedly connected to the substrate tape reel, then in the case of substrate depletion, the stepper motor can be stuck due to the end of the transmission of the substrate tape. In this case, the remaining amount of the substrate tape can be recorded. The output state of the substrate tape is determined according to the remaining amount of the substrate tape and the rotation speed of the stepper motor. Accordingly, the output state of the substrate tape further includes: abnormality due to the sticking, and abnormality due to the depletion of the substrate tape.

[0085] In another example of the present application, the two ends of the substrate tape can be arranged not to be fixed.

[0086] In an example of the present application, in the case where the first electrical signal is a pulse signal of the stepper motor and the pulse signal of the stepper motor is generated as the rotation shaft of the stepper motor rotates, the controller (which can include an MCU) of the aerosol generating device can adjust the pulse signal generated by the control IC for controlling the stepper motor according to the output state of the substrate tape.

[0087] In an example of the present application, the substrate tape output information processing method of the aerosol generating device includes the steps shown in FIG. 3.

[0088] Step S31: In the case where the aerosol generating device starts heating, obtain the puffing information.

[0089] Step S32: Generate the first driving signal of the stepper motor.

[0090] The first driving signal of the stepper motor can be a pulse signal, which is generated by the driving IC of the stepper motor for driving the stepper motor. As an example, the first driving signal can be generated by the MCU controlling the driving IC.

[0091] Step S33: Detect the coil current inside the stepper motor.

[0092] Step S34: Adjust the first driving signal of the stepper motor to obtain the second driving signal.

[0093] The second driving signal of the stepper motor can be a pulse signal, which is generated by the driving IC of the stepper motor for driving the stepper motor. As an example, the second driving signal can be generated by the MCU controlling the driving IC.

[0094] Step S35: Detect the frequency of the second driving signal.

[0095] After the driving IC generates the second driving signal, the second driving signal needs to be transmitted to the stepper motor through the connection circuit, and at the same time, the detection device can be connected between the driving IC and the stepper motor to detect the frequency of the first driving signal sent by the driving IC to the stepper motor or the frequency of the second driving signal.

[0096] In the present example, the first driving signal and the second driving signal can correspond to the first electrical signal in the foregoing embodiments.

[0097] Step S36: According to the comparison result of the frequency of the second driving signal and the reference frequency, determine the output state of the substrate tape as normal, stalled or broken.

[0098] In an example of the present application, in the case where the output state of the substrate tape indicates that the transmission of the substrate tape is abnormal, the aerosol generating device further generates an alarm signal and then outputs the alarm signal.

[0099] Exemplarily, the aerosol generating device is further provided with various suitable signal output devices, including but not limited to a display screen, a speaker, an indicator light, a buzzer, a vibration motor, and the like. In the case where the output state of the substrate strip indicates that the substrate strip is abnormally transported, the control output device outputs an alarm signal.

[0100] Exemplarily, the output alarm signal can include at least one of the following modes.

[0101] Mode one, outputting display information of an abnormal prompt. The display information can be a word, a number, a letter, or any character. Exemplarily, in the case where the display information is a word, the word content can include: abnormality.

[0102] Mode two, outputting an abnormal prompt sound or voice prompt.

[0103] Mode three, outputting indicator light information.

[0104] The indicator light information can include, for example, information that a specific color indicator light is lit, information that the indicator light is flashing, and the like.
