[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0020] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded 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 functions and arrangements of the elements described without departing from the scope of the present application. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described in some examples may be combined in other examples.

[0022] See also Figure 1 , Figure 1 : is a flow chart of a method for collecting cigarette smoke based on an external filter provided in an embodiment of the present application. In the embodiment of the present application, the method comprises: S101, obtaining a cigarette model of a target cigarette inserted into an external filter installation slot, and querying a first speed corresponding to the cigarette model.

[0023] The first speed is the volume expansion speed of the suction area of ​​the external filter in a non-sucking state.

[0024] The execution subject of the present application may be a controller of an external filter, or a cloud server that is communicatively connected to the controller of the external filter.

[0025] In the embodiment of the present specification, the external filter tip is used to install the installation slot of the cigarette and can be provided with a pressure sensor, an infrared sensor or other sensors to determine whether a cigarette is inserted into the installation slot through the sensor. When the installation slot is detected to be inserted into the target cigarette, the cigarette model of the target cigarette will be obtained, and the first speed matching the cigarette model will be queried in the preset database. Among them, the cigarette model can be determined by reading the identification code of the target cigarette, or by taking a photo of the cigarette by the terminal, and after the cigarette model is determined by image recognition, the terminal sends it to the controller through Bluetooth connection, communication connection, etc. The suction area of ​​the external filter tip can be an area directly connected to the user's mouth, and the smoke generated by the burning of the cigarette enters the user's mouth from the burning position through the suction area under the negative pressure generated by the suction of the user's mouth. The suction area is a cavity inside the external filter tip, and at least one cavity wall thereof can be set to a form that can be displaced by a spring, a motor, etc., so that the volume of the suction area is variable. Considering that different types of cigarettes have different parameters such as length, radius, and tobacco type, the amount of smoke generated by natural combustion per unit time is different, and the pressure required to draw these smoke into the suction area is also different. Therefore, the staff will test the first speed corresponding to the target cigarette of each cigarette model in advance through experiments. The first speed needs to match the natural combustion rate of the cigarette, that is, the pressure difference generated by the expansion of the volume of the suction area at the first speed can continuously draw the smoke generated by the new combustion into the suction area. At the same time, the first speed should not be too large, otherwise the pressure difference generated is too large, which will directly simulate the user's smoking situation and cause excessive burning of the cigarette. After setting the corresponding first speed for each cigarette model through testing, in actual situations, it is only necessary to query the matching first speed in the database by cigarette model.

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

[0027] In the embodiments of the present specification, a corresponding identification code can be set on the cigarette. After the insertion of the target cigarette is detected, 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 of the installation area, so as to query the cigarette model of the target cigarette based on the identification code information.

[0028] S102: determining a current use state based on a first change value of the cumulative amount of gas sucked in the suction area per unit time, and when the current use state is a non-suction state, continuously adjusting the area volume of the suction area based on the first speed.

[0029] In the embodiment of the present specification, the cumulative amount of gas sucked in the suction area can also be detected by setting a gas sensor or a fluid sensor in the suction area, and the controller will calculate the change value of the cumulative amount of gas sucked per unit time in real time. When the change value approaches 0, it means that there is no obvious flow of gas, that is, the cumulative amount of gas sucked has not changed significantly, which means that the user has not sucked, and this is a non-sucking state, otherwise it is a sucking state. After determining that the current use state is a non-sucking state according to the change value, it is considered that this is the user's suction interval and the user has not sucked. In order to avoid the escape of part of the smoke from the cigarette due to natural combustion during this period, the controller will continuously adjust the regional volume of the suction area at a first speed, so that the suction area continues to generate negative pressure due to the continuous increase in volume, and the smoke generated by the natural combustion of the cigarette is continuously sucked into the suction area by suction to prevent the smoke from escaping into the air.

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

[0031] In the embodiment of the present specification, after the controller obtains the cumulative gas suction volume in the suction area, it will calculate the first change value of the cumulative gas suction volume per unit time. A target value is set in the controller, and the target value can be 0 or a smaller value set after considering the error. When the first change value is less than the target value, the controller will determine the current use state as a non-suction state, that is, a state where the user does not perform suction. On the contrary, if the first change value is not less than the target value, the controller will determine the current use state as a suction state.

[0032] In one possible implementation, after determining the first change value of the cumulative gas suction amount per unit time, the method further includes: A second change value corresponding to the first speed is queried, and the second change value is set as a target value, where the second change value is a change value of the cumulative gas suction amount 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-sucking state, the suction area will change in volume according to the first speed to produce negative pressure to suck the smoke produced by natural combustion, this process will also cause the cumulative gas suction volume to change. In order to avoid misjudgment, in the process of preliminary test, the 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 by the first speed is determined. Therefore, the controller will query the second change value corresponding to the first speed and set the second change value to 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 inhaled and is in a non-sucking state.

[0034] In one embodiment, after continuously adjusting the regional volume of the suction region based on the first speed, the method further includes: After the area volume reaches the maximum volume of the suction area, suction prompt information is generated.

[0035] In the embodiments of this specification, the area volume of the suction area cannot be infinitely expanded, and the controller can determine whether the suction area has reached the maximum volume by the number of rotations of the motor used to adjust the volume of the suction area, the displacement of the cavity wall, etc. After the area volume of the suction area reaches the maximum volume, a suction prompt message will be generated to prompt the user to inhale, so as to avoid the inability to generate negative pressure due to the inability to increase the volume, so that the smoke generated by natural combustion begins to escape.

[0036] In one embodiment, the method further comprises: When the current use state is switched to the smoking state, the second speed corresponding to the cigarette model is queried, and the area volume is continuously adjusted based on the second speed until the area volume returns to the initial volume. The second speed is the volume reduction speed of the smoking area in the smoking state.

[0037] In the embodiments of this specification, after determining the first speed corresponding to the cigarette model during the preliminary test, the corresponding second speed can also be set according to experience. The setting of the second speed can enable the area volume to be restored to the initial volume according to the second speed after the user starts to inhale. In this way, on the one hand, it is ensured that the next round of natural combustion smoke collection can be carried out after the user stops inhaling. On the other hand, the reduction of the area volume can cooperate with the user's inhalation and transport the smoke to the user's oral cavity more efficiently. The user's single inhalation time is generally short, so the value of the second speed is generally set to be larger than the value of the first speed.

[0038] In one embodiment, the continuously adjusting the volume of the region based on the second speed includes: Calculating the volume difference between the maximum volume and the initial volume of the area volume, and calculating the average duration of a single puff based on historical puff data; A third speed is calculated according to the volume difference and a single average puffing time, and the volume of the region is continuously adjusted based on the third speed.

[0039] In the embodiments of the present specification, the controller can also determine the duration of each puff of the user based on the historical puff data, and calculate the average of these puff durations, that is, the average single puff duration. Next, the volume difference between the maximum volume and the initial volume of the regional volume is calculated, and the third speed can be calculated based on the volume difference and the average single puff duration. When the current use state is switched back to the puff state, the third speed will be used instead of the second speed to adjust the regional volume. Compared with the second speed, the third speed can better fit the user's own puffing habits, so that regardless of whether the regional volume is expanded to the maximum volume, the regional volume can be restored to the initial volume when the user completes a single puff, and the next round of automatic smoke collection will not be affected because the regional volume has not been restored to the initial volume when the user completes the puff.
