[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the following description, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The following description provides multiple embodiments of this application, which can be substituted or combined with each other. Therefore, this application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then this application should also be considered to include embodiments containing one or more other possible combinations of A, B, C, and D, even if such embodiments are not explicitly described in the following text.

[0021] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this application. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0022] See Figure 1 , Figure 1 This is a schematic flowchart illustrating a cigarette smoke collection method based on an external filter provided in an embodiment of this application. In this embodiment, the method includes: S101. Obtain the cigarette model of the target cigarette inserted into the external filter mounting slot, and query the first speed corresponding to the cigarette model.

[0023] Wherein, the first speed is the volume expansion rate of the suction area of ​​the external filter in the non-suction state.

[0024] The executing entity of this application may be the controller of the external filter or a cloud server that is communicatively connected to the controller of the external filter.

[0025] In the embodiments of this specification, the mounting slot for installing cigarettes in the external filter can be equipped with sensors such as pressure sensors and infrared sensors to determine whether a cigarette has been inserted into the mounting slot. When a target cigarette is detected inserted into the mounting slot, the cigarette model number is acquired, and a first speed matching the cigarette model is retrieved from a preset database. The cigarette model number can be determined by reading the identification code of the target cigarette, or by taking a picture of the cigarette with a terminal and determining the cigarette model through image recognition. The terminal then sends the information to the controller via Bluetooth, communication connection, or other means. The suction area of ​​the external filter can be an area directly connected to the user's mouth. The smoke generated by the combustion of the cigarette enters the user's mouth through the suction area under the negative pressure created by suction. The suction area is a cavity inside the external filter, and at least one cavity wall can be designed to be displaceable by springs, motors, or other means, thereby making the volume of the suction area variable. Considering that different cigarette models produce varying amounts of smoke per unit time due to differences in parameters such as length, radius, and tobacco type, the pressure required to draw this smoke into the suction area also varies. Therefore, staff will conduct pre-testing experiments to determine the appropriate initial speed for each cigarette model. This initial speed needs to match the cigarette's natural combustion rate; that is, the pressure difference generated by the expansion of the suction area at the initial speed should be sufficient to continuously draw the newly generated smoke into the suction area. Simultaneously, the initial speed should not be too high; otherwise, an excessive pressure difference would directly simulate the user's inhalation, leading to over-combustion of the cigarette. After setting the appropriate initial speed for each cigarette model through testing, in practice, it is only necessary to query the database for the matching initial speed for each cigarette model.

[0026] In one possible implementation, obtaining the cigarette model of the target cigarette inserted into the external filter mounting slot includes: After detecting that the target cigarette has been inserted into the external filter mounting slot, the identification code information of the mounting area is read, and the cigarette model of the target cigarette is queried based on the identification code information.

[0027] In the embodiments of this specification, a corresponding identification code can be set on the cigarette. After the target cigarette is detected to be inserted, the identification code will be exactly in the installation area of ​​the installation slot. The code reader set in the installation slot can scan the identification code information in the installation area, thereby querying the cigarette model of the target cigarette based on the identification code information.

[0028] S102. Determine the current usage state based on the first change value of the cumulative gas suction volume in the suction area per unit time. When the current usage state is a non-suction state, continuously adjust the area volume of the suction area based on the first speed.

[0029] In the embodiments of this specification, the cumulative gas volume in the suction area can also be detected by setting a gas sensor or a fluid sensor. The controller will calculate the change value of the cumulative gas volume per unit time in real time. When the change value approaches 0, it indicates that there is no obvious gas flow, that is, the cumulative gas volume has not changed significantly, meaning that the user has not been suctioning, and this is a non-suction state. Conversely, it is a suction state. After determining that the current usage state is a non-suction state based on the change value, it is considered that this is the user's suction interval, and the user has not performed a suction action. In order to prevent some smoke from escaping due to natural combustion of cigarettes during this period, the controller will continuously adjust the area volume of the suction area at the first speed, so that the suction area continuously generates negative pressure due to the continuous increase in volume, and continuously suctions the smoke produced by the natural combustion of cigarettes into the suction area through suction, preventing the smoke from escaping into the air.

[0030] In one possible implementation, determining the current usage status based on a first change in the cumulative gas extraction volume within the extraction area over a unit time includes: Obtain the cumulative gas suction volume in the suction area, and determine the first change value of the cumulative gas suction volume per unit time; When the first change value is less than the target value, the current usage state is determined to be a non-suction state; When the first change value is not less than the target value, the current usage state is determined to be the suction state.

[0031] In the embodiments described in this specification, after the controller obtains the cumulative gas suction volume in the suction area, it calculates the first change value of the cumulative gas suction volume per unit time. The controller has a target value set within it; the target value can be 0, or it can be a small value set after considering errors. When the first change value is less than the target value, the controller determines the current usage state as a non-suction state, i.e., a state where the user is not suctioning. Conversely, if the first change value is not less than the target value, the controller determines the current usage state as a suction state.

[0032] In one possible implementation, after determining the first change in the cumulative gas extraction volume per unit time, the method further includes: Query the second change value corresponding to the first speed, and set the second change value as the target value. The second change value is the change value of the cumulative gas suction volume per unit time when the suction area changes volume at the first speed.

[0033] In the embodiments of this specification, considering that in the non-suction state, the suction area will change volume according to the first speed to generate negative pressure to suction the flue gas produced by natural combustion, this process will also cause a change in the cumulative gas suction volume. To avoid misjudgment, during the preliminary test, a second change value corresponding to the first speed will also be tested, that is, the change value of the cumulative gas suction volume per unit time when the volume is adjusted at the first speed. Therefore, the controller will query the second change value corresponding to the first speed and set the second change value as the target value. As long as the first change value is less than the second change value, it is considered that the user has not performed suction, and the state is non-suction.

[0034] In one possible implementation, after continuously adjusting the volume of the suction region based on the first speed, the method further includes: Once the volume of the area reaches the maximum volume of the suction area, a suction prompt message is generated.

[0035] In the embodiments described in this specification, the volume of the suction area cannot be expanded indefinitely. The controller can determine whether the suction area has reached its maximum volume by adjusting the number of rotations of the motor used to adjust the volume of the suction area, the displacement of the cavity wall, etc. Once the volume of the suction area reaches its maximum, a suction prompt message will be generated to remind the user to perform suction, thus preventing the inability to continue generating negative pressure due to the inability to increase the volume, which would allow the smoke generated by natural combustion to begin to dissipate.

[0036] In one possible implementation, the method further includes: When the current usage state is switched to the inhalation state, the second speed corresponding to the cigarette model is queried, and the volume of the area is continuously adjusted based on the second speed until the volume of the area is restored to the initial volume. The second speed is the volume reduction speed of the inhalation area in the inhalation state.

[0037] In the embodiments of this specification, after determining the first speed corresponding to the cigarette model during preliminary testing, a corresponding second speed can be set based on experience. The second speed ensures that after the user begins to inhale, the volume of the inhaled area returns to its initial volume. This guarantees that after the user stops inhaling, the next round of natural combustion smoke collection can proceed. Furthermore, the reduced volume of the inhaled area allows for more efficient delivery of smoke to the user's mouth. Since a single inhalation session is generally short, the value of the second speed is typically set larger than the value of the first speed.

[0038] In one possible implementation, the step of continuously adjusting the region volume based on the second speed includes: Calculate the volume difference between the maximum volume and the initial volume of the region, and calculate the average suction time per session based on historical suction data; The third velocity is calculated based on the volume difference and the average suction time per cycle, and the volume of the region is continuously adjusted based on the third velocity.

[0039] In the embodiments described in this specification, the controller can also determine the duration of each user's vaping session based on historical vaping data, and calculate the average of these vaping durations, i.e., the average vaping duration per session. Next, the volume difference between the maximum and initial volumes of the calculated area is used. Based on this volume difference and the average vaping duration per session, a third speed can be calculated. When switching back to the vaping state from the current usage state, the third speed will replace the second speed for adjusting the area volume. This third speed, compared to the second speed, better suits the user's vaping habits, ensuring that regardless of whether the area volume expands to its maximum volume, it returns to its initial volume after the user finishes a single vaping session. This prevents the area volume from failing to return to its initial volume after the user finishes vaping, thus avoiding interference with the automatic collection of smoke in the next round.
