DETAILED DESCRIPTION

[0016] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described in detail with reference to the accompanying drawings. In the following description, specific details such as specific system structures, technologies, etc. are presented in order to explain rather than limit the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.

[0017] The application provides a breathing training method based on an aerosol generating device. The method is applied to a host computer in communication connection with the aerosol generating device. The host computer can be a smartphone, a notebook computer, a tablet computer, a smartwatch, or other electronic devices. The host computer can establish a communication connection with the aerosol generating device, such as a wired communication connection or a wireless communication connection. In an embodiment, the wireless communication connection adopts a BLE Bluetooth connection (Bluetooth Low Energy). In other embodiments, other wireless communication connections can also be adopted.

[0018] The aerosol generating device includes a heating unit, an aerosol forming substrate, a communication unit, a sensing unit, a mouthpiece, and a control unit. The control unit is connected with the heating unit, the communication unit, and the sensing unit. The heating unit heats the aerosol forming substrate to form an aerosol after being activated. A user inhales the aerosol by holding the mouthpiece. The sensing unit can monitor the user's behavior of inhaling the aerosol. The communication unit is used to establish a communication connection with the host computer. Before the breathing training starts, the aerosol generating device needs to complete the communication connection with the host computer to transmit various data.

[0019] As shown in FIG. 1, Figure 1 The application provides a breathing training method based on an aerosol generating device, which includes the following steps: S1, determining a target training scheme to output a breathing guidance instruction corresponding to the target training scheme to a user.

[0020] In this step, at least one breathing training scheme is provided, and each breathing training scheme is different in type (such as 4-7-8 breathing method, box breathing method), difficulty, and duration. The host computer can sequentially select multiple breathing training schemes as target training schemes in a certain order, or determine the breathing training scheme selected by the user as the target training scheme. The user can directly select the breathing training scheme through the host computer, or select the breathing training scheme through the interactive unit provided by the aerosol generating device, and then the aerosol generating device feeds back the selected breathing training scheme to the host computer. The host computer outputs a breathing guidance instruction corresponding to the target training scheme to the user. The breathing guidance instruction is used to guide the user to perform correct breathing training, such as starting to inhale and starting to exhale. Alternatively, the host computer can also send the breathing guidance instruction to the aerosol generating device, and then the aerosol generating device outputs the breathing guidance instruction to the user. The breathing guidance instruction can be in the form of visual, auditory, or tactile cues, such as the aerosol generating device being provided with an LED indication unit, and the color and brightness of the LED indication unit being controlled to change with the rhythm of inhalation / exhalation.

[0021] S2, obtaining user breathing data collected by the aerosol generating device in a breathing training mode.

[0022] The breathing training mode refers to disabling the aerosol generation function of the aerosol generating device, so as to ensure that no aerosol is generated during the breathing training process, to avoid safety hazards and confuse the user experience. Optionally, the control unit disables the aerosol generation function by cutting off the power supply of the heating unit of the aerosol generating device, at this time, the heating unit is in the off state, and the communication unit and the sensing unit are in the on state. The user can directly control the aerosol generating device to enter / exit the breathing training mode through the interactive unit of the aerosol generating device, for example, by pressing the button multiple times in succession, or can trigger the aerosol generating device to enter / exit the breathing training mode by sending instructions from the host computer. After the aerosol generating device enters or exits the breathing training mode, the host computer and / or the aerosol generating device can output corresponding prompts to the user.

[0023] The user holds the mouthpiece and completes inhalation and exhalation through the mouthpiece under the guidance of the breathing guidance instruction. The sensing unit collects the user's breathing data and transmits it to the control unit as time series data, and then transmits the user's breathing data to the host computer in real time through the communication unit. Further, the aerosol generating device can also preliminarily process the user's breathing data before sending it to the host computer, for example, data filtering.

[0024] S3, analyzing the user's breathing data and giving feedback information.

[0025] The host computer can analyze the user's breathing data during and / or after the breathing training, and give corresponding feedback information according to the analysis result.

[0026] Compared with the breathing training scheme in the related art, the embodiment determines the target training scheme, and outputs corresponding breathing guidance instructions to the user, so as to guide the user to perform correct breathing training and improve the training effect. The host computer analyzes the user's breathing data collected by the aerosol generating device and gives feedback information, which can provide an effective feedback mechanism and improve the user experience. In addition, as the popularity of the aerosol generating device increases, the embodiment utilizes the original functions of the aerosol generating device and the user's usage habits, and combines the host computer to realize interactive breathing training, which can provide more convenient and personalized breathing training experience, and avoid the purchase of professional breathing training equipment, thereby reducing the cost.

[0027] In an embodiment, the feedback information includes breathing adjustment instructions; as Figure 2 shown, the step S3 of analyzing the user's breathing data and giving feedback information includes: S31, comparing the user's breathing data with the target breathing data corresponding to the target training scheme.

[0028] S32, generating corresponding breathing adjustment instructions according to the deviation of the two and giving prompts.

[0029] In the embodiment, the breathing regulation instruction is used to guide the user to adjust the breathing behavior, such as adjusting the breathing rhythm or intensity. During the breathing training process, the host computer compares the user breathing data with the target breathing data in real time and gives the breathing regulation instruction in real time, which can help the user to find and correct the improper training in time, and help to improve the quality and efficiency of the overall training.

[0030] Alternatively, the target breathing data includes an ideal time sequence of inhale-hold-exhale-hold and a breathing intensity curve. The host computer judges the start, duration and end of exhalation, holding and inhalation based on the changes of the user breathing data. Optionally, the whole breathing training process can be divided into stages, which can consist of one or more steps of exhalation, inhalation and holding, and can be repeated, for example, each inhalation, holding and exhalation is a stage, or one or more “inhalation + holding + exhalation + holding” is a stage. After the user completes an action of a stage, the host computer compares the user breathing data of the stage with the target breathing data by using a preset matching algorithm, quantifies the matching degree and identifies the deviation, and then generates the corresponding breathing regulation instruction according to the deviation of the two. The matching algorithm can use dynamic time warping (DTW) algorithm or other time series similarity algorithm.

[0031] For example, when there is a certain deviation between the user breathing rhythm and the target breathing rhythm, the user can be prompted to adjust the breathing rhythm of the next stage by the breathing regulation instruction. When there is a certain deviation between the user breathing intensity and the target breathing intensity, the user can be prompted to adjust the breathing intensity of the next stage by the breathing regulation instruction. During the whole breathing training process, feedback is continuously given according to the user breathing data of each stage, which is a real-time feedback closed loop, guiding the user to continuously adjust the breathing.

[0032] In some embodiments, the prompting mode of the breathing regulation instruction includes at least one of a visual prompting mode, an auditory prompting mode and a tactile prompting mode.

[0033] The visual prompting mode refers to a mode of prompting or guiding the user by visual means. The auditory prompting mode refers to a mode of prompting or guiding the user by auditory means. The tactile prompting mode refers to a mode of prompting or guiding the user by tactile means. According to different needs and situations, the visual prompting mode, the auditory prompting mode and the tactile prompting mode can be selected as needed, which can better meet the needs of different users, adapt to various environments and situations, and enhance the user experience.

[0034] In some embodiments, the visual prompting manner includes a first visual prompting manner and / or a second visual prompting manner. The first visual prompting manner is to prompt the corresponding breathing regulation instruction by controlling different lighting modes of an LED indicating unit of the aerosol generating device. The second visual prompting manner is to prompt the corresponding breathing regulation instruction by controlling different display modes of a display unit of the aerosol generating device and / or the host computer.

[0035] The present application provides the first visual prompting manner and the second visual prompting manner. According to actual needs, the first visual prompting manner and the second visual prompting manner can be used simultaneously, or only one of the prompting manners can be used.

[0036] The aerosol generating device is also provided with an LED indicating unit connected to the control unit. When the first visual prompting manner is used, the host computer sends an LED control instruction to the aerosol generating device, and the control unit controls the lighting mode of the LED indicating unit according to the LED control instruction, thereby prompting the corresponding breathing regulation instruction. The lighting mode includes but is not limited to color change, flashing frequency, flashing times, lighting time, and brightness change. For example, slow flashing indicates “inhale a little slower”, and fast flashing indicates “inhale a little faster”.

[0037] The aerosol generating device is also provided with a display unit connected to the control unit, and the display unit uses a display screen. The host computer sends a display instruction to the aerosol generating device, and the display unit of the aerosol generating device displays different display modes according to the display instruction, thereby prompting the corresponding breathing regulation instruction. The display mode includes but is not limited to text prompt, progress bar change, dynamic comparison of the user's breathing curve and the target breathing curve, and color change of the user's breathing curve. Alternatively, the host computer is also provided with a display unit, and the host computer can send the display instruction to the display unit of itself for prompting.

[0038] In some embodiments, the audible prompting manner is to prompt the corresponding breathing regulation instruction by controlling different sound output modes of a sound output unit of the aerosol generating device and / or the host computer.

[0039] The aerosol generating device is also provided with a sound output unit connected to the control unit, and the sound output unit uses a loudspeaker. The host computer sends a sound output instruction to the aerosol generating device, and the sound output unit of the aerosol generating device outputs different sound output modes according to the sound output instruction, thereby prompting the corresponding breathing regulation instruction. The sound output mode includes but is not limited to beat sound, voice guidance, and soothing music. Alternatively, the host computer is also provided with a sound output unit, and the host computer can send the sound output instruction to the sound output unit of itself for prompting.

[0040] In some embodiments, the haptic prompting mode is to prompt the corresponding breathing regulation instruction by controlling different vibration modes of a vibration unit of the aerosol generating device and / or the host computer.

[0041] The aerosol generating device is further provided with a vibration unit connected with the control unit, and the vibration unit adopts a vibration motor. The host computer sends a vibration instruction to the aerosol generating device, and the vibration unit of the aerosol generating device generates different vibration modes according to the sound generation instruction, thereby prompting the corresponding breathing regulation instruction. The vibration mode includes but is not limited to vibration frequency, vibration times, and vibration time. Alternatively, the host computer is also provided with a vibration unit, and the host computer can send a vibration instruction to the vibration unit of itself for prompting.

[0042] In some embodiments, the user breathing data includes at least one of an airflow pressure signal, an airflow velocity signal, and an airflow sound signal generated by the user breathing. The airflow pressure signal is collected by a pressure sensing unit in the aerosol generating device, the airflow velocity signal is collected by an airflow sensing unit in the aerosol generating device, and the airflow sound signal is collected by a sound collecting unit in the aerosol generating device.

[0043] In some automatic inhalation trigger starting aerosol generating devices, a pressure sensing unit is arranged inside the device, and the pressure sensing unit adopts a pressure sensor. When the user inhales or exhales, a pressure difference relative to the ambient pressure is generated in the airflow channel inside the aerosol generating device, and the pressure sensing unit is used to measure the pressure difference generated by inhalation / exhalation to obtain an airflow pressure signal. According to the change relationship of the airflow pressure signal with time, a breathing curve can be formed, which can intuitively show the user's breathing training situation. In the curve, as the inhalation starts, the airflow pressure signal rises rapidly, reaches a peak (indicating the moment when the inhalation is the strongest), and then gradually decreases as the inhalation ends until it returns to zero (ambient pressure).

[0044] In some aerosol generating devices, an airflow sensing unit is further arranged inside the device, and the airflow sensing unit adopts an airflow sensor. When the user inhales or exhales, the gas in the airflow channel inside the aerosol generating device flows, and the airflow sensing unit is used to measure the airflow velocity and direction to obtain an airflow velocity signal, and according to the measured direction, the inhalation or exhalation can be determined. According to the change relationship of the airflow velocity signal with time, a breathing curve can be formed, which can intuitively show the user's breathing training situation. The change of the breathing curve formed by the airflow velocity signal is similar to that of the airflow pressure signal, which will not be described here.

[0045] In some aerosol-generating devices, a sound collecting unit is further arranged inside the device, and the sound collecting unit adopts a microphone. When a user inhales or exhales, breathing sound is generated, and the sound collecting unit is used to measure the breathing to obtain an airflow sound signal. According to the change relationship of the airflow sound signal over time, a breathing curve can be formed, and the breathing training condition of the user can be intuitively displayed. When the user inhales, the breathing sound pressure rises, and when the user finishes inhaling, the breathing sound pressure falls. According to the airflow sound signal, the breathing action of the user can be recognized, and the breathing stability can be judged.

[0046] According to different needs and situations, the airflow pressure signal, the airflow speed signal, and the airflow sound signal can be selected as needed.

[0047] In an embodiment, the feedback information includes a breathing score; as Figure 3 As shown in FIG. 3, the step S3 of analyzing the user breathing data and giving feedback information includes: S33, extracting a user breathing feature value from the user breathing data.

[0048] S34, calculating a breathing score according to the user breathing feature value and a target breathing feature value corresponding to the target training scheme.

[0049] After the user completes the entire training process or the user ends the training, the host computer extracts the user breathing feature value from the user breathing data in the entire process based on a preset threshold or a preset change rate, and then combines the target breathing feature value corresponding to the target training scheme to calculate the breathing score of the entire training process based on a preset calculation formula. By feeding back the breathing score to the user, the user can intuitively, accurately, and clearly master the breathing training effect. For the breathing score, visual, auditory, and tactile prompt methods can also be used, and details are not repeated here, and reference can be made to the previous embodiments. In addition, the host computer can also calculate and output the breathing score of a stage after the user completes the action of the stage. Further, the host computer can also rate the training effect of the user based on the breathing score.

[0050] In an embodiment, the user breathing feature value includes at least one of the following: user breathing duration, user breathing intensity, and user breathing curve.

[0051] The user breathing duration includes at least one of the user inhalation duration, the user holding duration, and the user exhalation duration. The target breathing feature value includes a target breathing duration, which corresponds to the user breathing duration and includes at least one of a target inhalation duration, a target holding duration, and a target exhalation duration. The inhalation duration is the duration from the start of inhalation to the end of inhalation, the holding duration is the duration from the end of inhalation to the start of exhalation, and the exhalation duration is the duration from the start of exhalation to the end of exhalation.

[0052] The user breathing intensity includes at least one of a user exhale intensity and a user inhale intensity. The target breathing characteristic value includes at least one of a target exhale intensity and a target inhale intensity corresponding to the user breathing intensity. The exhale intensity is a peak value in the exhale process, such as a maximum pressure difference or a maximum flow rate during exhale. The inhale intensity is a peak value in the inhale process.

[0053] The user breathing curve includes at least one of a user inhale curve and a user exhale curve. The target breathing characteristic value includes at least one of a target inhale curve and a target exhale curve corresponding to the user breathing curve. The inhale curve is a time sequence of breathing data in an inhale phase. The exhale curve is a time sequence of breathing data in an exhale phase.

[0054] In some embodiments, when the user breathing characteristic value includes a user breathing duration, the target breathing characteristic value includes a target breathing duration, and the breathing score includes a breathing duration score. The breathing score calculated according to the user breathing characteristic value and the target breathing characteristic value corresponding to the target training scheme in step S34 includes: S341, based on the user breathing duration, the target breathing duration, and a preset duration deviation penalty coefficient, a breathing duration score is calculated.

[0055] In this step, the breathing duration score includes at least one of an inhale duration score, an exhale duration score, and a hold duration score, and the breathing duration score is a weighted average of the various duration scores it includes. The calculation methods of the inhale duration score, the exhale duration score, and the hold duration score are similar. The calculation method is described below by taking the inhale duration score as an example: the absolute value of the difference between the user inhale duration and the target inhale duration is multiplied by the duration deviation penalty coefficient, the preset full score value is subtracted from the product, and the result obtained is the inhale duration score. When the result is less than 0, the inhale duration score is 0. The preset full score value and the duration deviation penalty coefficient can be set according to actual needs. In this embodiment, the preset full score value is 100 points; and the duration deviation penalty coefficient is: 5 points are deducted for every 0.1s difference between the user inhale duration and the target inhale duration.

[0056] When the user breathing characteristic value includes a user breathing intensity, the target breathing characteristic value includes a target breathing intensity, and the breathing score includes a breathing intensity score. The breathing score calculated according to the user breathing characteristic value and the target breathing characteristic value corresponding to the target training scheme in step S34 includes: S342, based on the user breathing intensity, the target breathing intensity, and a preset intensity deviation penalty coefficient, a breathing intensity score is calculated.

[0057] In this step, the breathing intensity score includes at least one of the inhalation intensity score and the exhalation intensity score, and the breathing intensity score is a weighted average of the various intensity scores included therein. The inhalation intensity score and the exhalation intensity score are calculated in a similar manner, which will be described below by taking the inhalation intensity score as an example: the absolute value of the relative deviation of the user's inhalation intensity from the target inhalation intensity is multiplied by an intensity deviation penalty coefficient, the preset full score value is subtracted from the product, and the result is the inhalation intensity score. When the result is less than 0, the inhalation intensity score is 0. The preset full score value and the intensity deviation penalty coefficient can be set according to actual needs. In this embodiment, the preset full score value is 100 points; and the intensity deviation penalty coefficient is: 10 points are deducted for every 10% deviation between the user's inhalation duration and the target inhalation duration.

[0058] When the user's breathing characteristic value includes a user's breathing curve and the target breathing characteristic value includes a target breathing curve, the breathing score includes a curve shape score. The breathing score calculated in step S34 according to the user's breathing characteristic value and the target breathing characteristic value corresponding to the target training scheme includes: S343, based on the user's breathing curve and the target breathing curve, a curve shape score is calculated by combining a preset matching algorithm.

[0059] In this step, the curve shape score includes at least one of the inhalation curve score and the exhalation curve score, and the curve shape score is a weighted average of the various curve scores included therein. The inhalation curve score and the exhalation curve score are calculated in a similar manner, which will be described below by taking the inhalation curve score as an example: the DTW distance between the user's inhalation curve and the target inhalation curve is calculated, the calculated DTW distance is divided by the theoretical maximum DTW distance of the inhalation stage, 1 is subtracted from the result of the division, and the product of the difference and the preset full score value is calculated. The result is the inhalation curve score. When the result is less than 0, the inhalation curve score is 0. The preset full score value can be set according to actual needs. In this embodiment, the preset full score value is 100 points.

[0060] Further, weights corresponding to the breathing duration score, the breathing intensity score, or the curve shape score included in the breathing score are set, each score is multiplied by the corresponding weight, and then added to obtain the breathing score. The weights can be adjusted according to the actual training focus, for example, the breathing intensity training is the most important, and the weight of the breathing intensity score is set to the highest.

[0061] Further, after the user completes the entire training process or the user ends the training, the aerosol-generating device exits the breathing training mode, the host computer calculates the breathing score of the user and prompts the user, for example, displays the breathing score and the user's breathing curve graph.

[0062] In one embodiment, an aerosol generating device is also provided, comprising a sensing unit and a communication unit. The sensing unit collects user breathing data when the aerosol generating device is in breathing training mode. The communication unit communicates with a host computer and sends the user breathing data to the host computer. The host computer is used to determine a target training plan, output breathing guidance instructions corresponding to the target training plan to the user, and analyze the received user breathing data and provide feedback information.

[0063] Furthermore, the aerosol generation device also includes a heating unit, an aerosol forming matrix, a mouthpiece, and a control unit. The control unit is connected to the heating unit, communication unit, and sensing unit. After the heating unit is activated, it heats the aerosol forming matrix to generate aerosol. The user inhales the aerosol through the mouthpiece. The sensing unit monitors the user's aerosol inhalation behavior. The communication unit establishes a communication connection with the host computer. Before breathing training begins, the aerosol generation device needs to establish a communication connection with the host computer for data transmission.

[0064] During breathing training, the aerosol generating device is in breathing training mode, and the aerosol generation function is disabled. The sensing unit collects the user's breathing data, and the control unit controls the communication unit to send the user's breathing data to the host computer. The host computer is used to execute the breathing training method based on the aerosol generating device disclosed in any embodiment of this application.
