[0042] The present application aims to timely remind users to replace the external liquid storage chamber, and provides an oil warning system, an aerosol generating device, and an aerosol generating system. The aerosol generating device is provided with an air flow channel, and the aerosol generated by the atomizing assembly flows through the air flow channel to the outside of the aerosol generating device. The oil warning system includes a detecting member, a controlling member, and a reminding member. The detecting member detects the target information of the air flow in the air flow channel. When the user sucks, the atomizing assembly normally heats and atomizes to generate a large amount of aerosol flowing into the air flow channel. When the liquid aerosol generating matrix is gradually exhausted, the atomizing assembly burns dry, causing a change in the target information of the air flow in the air flow channel. The detecting member detects the change in the air flow in the air flow channel and sends the target information to the controlling member. After processing, the controlling member issues a reminder instruction to the reminding member to drive the reminding member to send a prompt signal to the user to remind the user to add the liquid aerosol generating matrix in time, effectively ensuring the user's taste. For details, please refer to the following embodiments.

[0043] Please refer to Figure 1 and Figure 2 In the first embodiment of the present application, an aerosol generating system 1000 is provided, which includes an aerosol generating device 100 and an external unit 200. The aerosol generating device 100 atomizes and heats the aerosol generating matrix to generate aerosol for the user to use. The external unit 200 is installed outside the aerosol generating device 100 and is used to store the liquid aerosol generating matrix and supply the liquid aerosol generating matrix to the aerosol generating device 100. The user can add the liquid aerosol generating matrix to the aerosol generating device 100 through the external unit 200, extending the service life of the aerosol generating system 1000 and the aerosol generating device 100.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 Among them, the aerosol generating device 100 includes a housing 10, an atomizing assembly 20, and an oil warning system 30. The housing 10 has an air flow channel 11. The atomizing assembly 20 is used to heat the aerosol generating matrix to generate aerosol. The atomizing assembly 20 is at least partially located in the air flow channel 11, so that the aerosol generated by heating and atomizing the atomizing assembly 20 can flow out through the air flow channel 11.

[0045] Please refer to Figure 1 , Figure 3 and Figure 4, in this embodiment, the fuel warning system 30 may include a detector 31, a controller 32, and a reminder 33. The detector 31 is at least partially disposed in the air flow channel 11, facilitating the detector 31 to directly collect the target information of the air flow in the air flow channel 11; the target information may be the air flow intensity, aerosol concentration, temperature, humidity, etc. of the aerosol; the controller 32 is electrically connected to the detector 31, and the controller 32 is configured to receive the target information collected or sent by the detector 31, compare the acquired target information with a preset value, and if the preset value is reached, determine the air flow state in the air flow channel 11, and then issue a corresponding reminder instruction; the reminder 33 is electrically connected to the controller 32, and the reminder 33 receives and responds to the reminder instruction issued by the controller 32 to realize reminding the user.

[0046] Specifically, when the user sucks, the atomization component 20 normally heats and atomizes to generate a large amount of aerosol flowing into the air flow channel 11. When the liquid aerosol generation matrix is gradually exhausted, the atomization component 20 undergoes dry burning, and the target information of the air flow entering the air flow channel 11 will change. For example, the air flow intensity, aerosol concentration, humidity, temperature, etc. change; the detector 31 is used to collect the target information of the air flow in the air flow channel 11 and send the collected target information to the controller 32. The controller 32 receives the target information and performs simple processing on the target information. The processing method may be to compare the target information with a preset value. For example, when the user sucks, if the aerosol concentration collected by the detector 31 is continuously lower than a certain preset value, the air flow intensity is continuously lower than a certain preset value, or the humidity is lower than a certain preset value, etc., it can be determined that the atomization component 20 has exhausted or is about to exhaust the liquid aerosol generation matrix. The controller 32 issues a reminder instruction to the reminder 33, and the reminder 33 receives and responds to the reminder instruction to remind the user to add the liquid aerosol generation matrix in time, effectively ensuring the user's taste, and also avoiding damage to the atomization component 20 caused by dry burning, and extending the service life of the aerosol generating device 100 and the aerosol generating system 1000. The controller 32 having a comparison circuit can achieve the above functions. The reminder 33 may adopt at least one of a warning light 331, a polarized motor 332, and a buzzer 333. When the warning light 331 responds to the reminder instruction, the warning light 331 can change from off to flashing or continuously lit; when the polarized motor 332 responds to the reminder instruction, the polarized motor 332 can change from non-vibrating to intermittent vibration or continuous vibration; when the buzzer 333 responds to the reminder instruction, the buzzer 333 can change from silent to continuously emitting a beeping sound or intermittently emitting a beeping sound at fixed intervals; through the above actions, a simple and direct reminder to the user can be realized.

[0047] Please continue to refer to Figure 1 and Figure 2, in this embodiment, the external unit 200 can be a component independent of the aerosol generating device 100 and is installed outside the aerosol generating device 100. It is used to store the liquid aerosol generating matrix and supply the liquid aerosol generating matrix to the aerosol generating device 100, so that the liquid aerosol generating matrix in the aerosol generating device 100 can be replenished when it has been exhausted or is about to be exhausted, ensuring the continuous use of the aerosol generating device 100 and the aerosol generating system 1000. A first connection structure 12 is provided on the housing 10 of the aerosol generating device 100, and a second connection structure 201 is provided on the external unit 200. The second connection structure 201 is connected to the first connection structure 12, so that the external unit 200 can be installed and fixed outside the aerosol generating device 100 through the second connection structure 201, and the installation is very convenient. After the external unit 200 is installed on the aerosol generating device 100, the liquid aerosol generating matrix stored in the external unit 200 can flow into the aerosol generating device 100.

[0048] Please continue to refer to Figure 3 , in one embodiment, a liquid storage cavity 13 and a receiving cavity 14 are formed in the housing 10. The liquid storage cavity 13 is used to store the liquid aerosol generating matrix, and the air flow channel 11 passes through the liquid storage cavity 13. External air can pass through the liquid storage cavity 13 via the air flow channel 11. The aerosol generating device 100 is further provided with a central tube 40 and a mouthpiece 50. The central tube 40 surrounds and forms part of the air flow channel 11. One end of the central tube 40 is connected to the atomization assembly 20, and the end of the central tube 40 far from the atomization assembly 20 is connected to the mouthpiece 50. When the user sucks, external air enters the air flow channel 11, flows through the atomization assembly 20, and the aerosol generated by the atomization assembly 20 flows to the mouthpiece 50 via the central tube 40. The mouthpiece 50 is connected to the outside of the housing 10, so that the user can suck the aerosol generated by atomization through the mouthpiece 50. The receiving cavity 14 is used to install various components. For example, the control member 32 and the reminder member 33 are received in the receiving cavity 14.

[0049] Please continue to refer to Figure 3 , in one embodiment, the aerosol generating device 100 is provided with a liquid guiding tube 60. One end of the liquid guiding tube 60 is connected to the liquid storage cavity 13, and the other end of the liquid guiding tube 60 extends out of the housing 10 and is used to communicate with the external unit 200, so that the liquid aerosol generating matrix in the external unit 200 can flow into the liquid storage cavity 13 via the liquid guiding tube 60 to replenish the liquid aerosol generating matrix in the liquid storage cavity 13.

[0050] Please continue to refer to in combination with Figure 3 and Figure 4, in one embodiment, the target information is the number of times the airflow passes through the airflow channel 11; the detection member 31 employs an airflow sensor 311, and the airflow sensor 311 collects the target information, that is, the number of times the airflow passes through the airflow channel 11; the control member 32 receives the number of times the airflow passes through the airflow channel 11 collected by the detection member 31, and when it determines that the number of times the airflow passes through is greater than the preset number of times, it sends a reminder instruction to the reminder member 33; the reminder member 33 receives the reminder instruction and makes a response to remind the user to add the liquid aerosol generation matrix in a timely manner; during the user's suction process, the airflow in the airflow channel 11 changes (whether it passes through or not), and the airflow sensor 311 detects this airflow change. One airflow change corresponds to one suction action, so that the airflow sensor 311 detects the user's suction action, and the cumulative number of the user's suction actions is collected through the airflow sensor 311. When the space of the liquid storage cavity 13 in the aerosol generation device 100 in use is the same, that is, when the stock of the liquid aerosol generation matrix is basically the same, the number of available suction times after the aerosol generation device 100 is heated and atomized remains within a fixed range. By collecting the number of times the airflow passes through the airflow channel 11 through the airflow sensor 311, when the control member 32 determines that the number of times the airflow passes through is greater than the preset number of times, it can be determined that the atomization component 20 has exhausted or is about to exhaust the liquid aerosol generation matrix, and then a reminder instruction is sent to the reminder member 33 to remind the user to add the liquid aerosol generation matrix in a timely manner, effectively ensuring the user's taste, and also avoiding damage to the atomization component 20 caused by dry burning, and prolonging the service life of the aerosol generation device 100. The preset number of times is not limited to a certain determined value and can be a range value. The determination of the preset number of times can be obtained after statistics of multiple test groups, for example, taking the average value.

[0051] Please continue to refer to Figure 3 and Figure 4 , further, the airflow sensor 311 is a microphone 3111, and the aerosol generation device 100 is provided with a microphone 3111, so that the fuel warning system 30 can directly use the existing microphone 3111, which is beneficial to cost savings.

[0052] Please continue to refer to Figure 3 and Figure 4, in one embodiment, the target information may be at least one of the concentration and humidity of the aerosol in the air flow channel 11; the detection member 31 employs at least one of a concentration sensor 312 and a humidity sensor 313. The concentration sensor 312 collects the concentration of the aerosol in the air flow channel 11, and the humidity sensor 313 collects the humidity of the aerosol in the air flow channel 11; the control member 32 receives the concentration of the aerosol or the humidity of the aerosol, and when it determines that the concentration of the aerosol in the air flow channel 11 is lower than a preset concentration and / or the humidity of the aerosol in the air flow channel 11 is lower than a preset humidity, it sends a reminder instruction to the reminder member 33; the reminder member 33 receives the reminder instruction and makes a response to remind the user to add the liquid aerosol generation matrix in time. When the user inhales the aerosol generating device 100, the atomization assembly 20 normally heats and atomizes to generate a large amount of aerosol flowing into the air flow channel 11. After the liquid aerosol generation matrix is gradually exhausted or completely exhausted, the atomization assembly 20 will dry burn, and the concentration or humidity of the aerosol entering the air flow channel 11 will change. The control member 32 receives the target information (i.e., the concentration or humidity of the aerosol) collected by the concentration sensor 312 or the humidity sensor 313. When the concentration value of the concentration sensor 312 is lower than the preset concentration or the humidity value of the humidity sensor 313 is lower than the preset humidity, it can be determined that the atomization assembly 20 has exhausted or is about to exhaust the liquid aerosol generation matrix, and then a reminder instruction is sent to the reminder member 33, so that the reminder member 33 makes a response to give a prompt to the user to remind the user to add the liquid aerosol generation matrix in time, effectively ensuring the user's taste, and also avoiding damage to the atomization assembly 20 caused by dry burning, and prolonging the service life of the aerosol generating device 100 and the aerosol generation system 1000. The preset concentration or preset humidity is not limited to a certain definite value and may be a range value. The determination of the preset concentration or preset humidity can be obtained by taking statistical values of the gas concentration or gas humidity generated by the atomization assembly 20 when the liquid aerosol generation matrix is exhausted or about to be exhausted using multiple test groups, for example, taking the average value. Since the aerosol generated by the atomization assembly 20 flows out from the air outlet end of the air flow channel 11, the concentration sensor 312 or the humidity sensor 313 can be installed at a position close to the air outlet end in the ventilation to accurately measure the concentration or humidity of the aerosol in the air flow channel 11.

[0053] In summary, the present application provides an oil warning system, an aerosol generating device and an aerosol generating system; the aerosol generating device is provided with an air flow channel, and the aerosol generated by the atomization assembly flows through the air flow channel to the outside of the aerosol generating device; the oil warning system includes a detection member, a control member and a reminder member, and the detection member detects the target information of the air flow in the air flow channel; when the user sucks, the atomization assembly normally heats and atomizes to generate a large amount of aerosol flowing into the air flow channel, and when the liquid aerosol generating matrix is gradually exhausted, the atomization assembly dry burns, causing the target information of the air flow in the air flow channel to change. The detection member is used to detect the change of the air flow in the air flow channel, send the target information to the control member, and the control member sends a reminder instruction to the reminder member after processing, driving the reminder member to send a prompt signal to the user to remind the user to add the liquid aerosol generating matrix in time, effectively ensuring the user's taste.
