Further, the first pressure sensor is arranged between the liquid storage cavity and the isolation device and is used for collecting a first pressure parameter of the liquid storage cavity. The first pressure parameter may be a pressure value generated by the aerosol substrate in the reservoir to the base 20. It will be appreciated that the first pressure sensor may be provided inside the atomizer, i.e. at the bottom of the reservoir, i.e. at the side of the base facing the reservoir; at this time, a data interface of the pressure sensor may be provided at the bottom of the base, so that the host computer can read the first pressure parameter. Of course, based on the inventive concept of the present application, the first pressure sensor may be disposed at one side of the host, and the pressure sensor is extended from the base into the liquid storage cavity, so that the influence on the pressure detection value due to the base is reduced; or a through hole corresponding to the position of the pressure sensor can be arranged in the base, a sealing film layer is arranged on the through hole, the pressure of aerosol is conducted by the film layer, and the first pressure sensor is also positioned on one side of the host without penetrating through the base.
Further, a liquid level measuring mechanism can be further arranged in the atomizer, and the liquid level measuring mechanism can be used for measuring the distance between the liquid level of the aerosol base material and the top of the liquid storage cavity. Specifically, the liquid level measuring mechanism may include a distance measuring device, where the distance measuring device is mainly used to measure the distance between the liquid level of the aerosol substrate and the top of the liquid storage cavity. Specifically, the distance measuring device may be disposed on a side wall of the atomizer, for example, a pressure sensor or a capacitor may be additionally disposed on the side wall of the atomizer, and the liquid level position of the aerosol substrate is sensed through detection of a pressure value or a capacitor. The host may receive data acquired by the level measurement mechanism.
Further, the host computer may further include an alarm for sending an alarm when the liquid level of the aerosol substrate reaches a preset value, prompting the user to stop using or to rejoin the aerosol substrate. Specifically, the alarm may be disposed on the main circuit board 17, for example, a vibration element, a buzzer, or an LED lamp may be disposed on the main circuit board 17, so as to issue an alarm when the liquid level of the aerosol base material reaches a preset value. It will be appreciated that the alarm may also be used to alert the user when the density of the aerosol substrate is outside a predetermined normal range.
Further, a processor and a memory may be provided in the host circuit board 17. The processor can be used for controlling the power output to the atomizer, and the power of the atomizer can be determined according to parameters received by the host; the memory may be used to store temperature information collected in real time as well as pressure parameters. The processor is electrically connected with the memory. It will be appreciated that the processor and memory types are various, and the application is not limited to the processor and memory of the host circuit board.
In actual operation, first, the temperature of the bottom surface of the liquid storage cavity can be measured by using the temperature sensor, and the first pressure parameter of the bottom surface of the liquid storage cavity can be measured by using the first sensor. And then the temperature of the bottom surface of the liquid storage cavity and the first pressure parameter of the bottom surface of the liquid storage cavity are sent to a processor of a host circuit board through an isolation device.
Further, the host circuit board may calculate the actual temperature of the aerosol substrate in the liquid storage cavity according to the temperature of the bottom surface of the liquid storage cavity, where the actual temperature of the aerosol substrate is related to the thermal conductivity and the thickness of the base. The host circuit board can then look up a density table stored in the memory according to the actual temperature of the aerosol substrate, which can be preset in the memory, and characterize the correlation of the density of the aerosol substrate with the pressure at the bottom of the liquid storage cavity at different temperatures. Then, the host circuit board can determine the volume of the current aerosol base material according to the first pressure parameter of the bottom surface of the liquid storage cavity and the distance measured by the distance measuring device, and simultaneously determine the weight of the current aerosol base material by using the first pressure parameter, so as to calculate and obtain the density of the aerosol base material in the liquid storage cavity, and compare the density with the density stored in a preset memory, thereby determining whether the density of the aerosol base material is in a normal range. If the density of the aerosol base material is within a preset normal range, determining that the quality of the aerosol base material is good; if the density of the aerosol base material is out of the preset normal range, determining that the quality of the aerosol base material is poor, and sending out alarm information by an alarm to remind a user of not sucking the aerosol base material in the atomizer.
Further, since different aerosol substrates are filled in different types of atomizers and correspond to different substances and different densities, a plurality of corresponding electrical parameters with different characteristics can be set in the atomizers, and the types of the atomizers can be identified through the electrical parameters. For example, the electrical parameters of the different features may be different resistance or inductance parameters of the atomizing core, or parameters associated with the individual components.
Further, the density table in the host circuit board may be divided into a plurality of levels, and each level may correspond to a fixed density range. When the measurement is carried out, if the density of the aerosol base material is too far away from the normal value, the aerosol base material possibly mixed with heavy metals is indicated, and at the moment, the alarm can send out continuous alarm information to prompt the user with the highest safety level. The density of the aerosol base material is not greatly different from a normal value, so that the aerosol base material has low harmfulness, and the alarm can only prompt the aerosol base material in sequence at the moment, and can be recovered to be used after confirmation by a user.
Further, due to the aerosol substrate in the atomizer, the substances inside the atomizer oxidize and volatilize with contact with air, resulting in a change in the density of the aerosol substrate with increasing use time. Depending on the different components added to the aerosol substrate, the initial state may be larger or smaller. Therefore, in the embodiment of the application, the density data of each type of aerosol base material after different use time is counted through experiments in advance, and the density data pre-stored in the density table stored in the memory is divided into a normal grade, a deterioration grade and a toxic grade. When the atomizer is plugged into the host for use, the host can record the use time of the atomizer. After the host calculates the density of the aerosol base material in the atomizer, the host can judge whether the aerosol base material belongs to a modified aerosol base material or not and whether the aerosol base material belongs to a toxic aerosol base material or not according to the service time of the atomizer. In alarming, different alarming modes can be adopted for the deteriorated aerosol base material and the poisonous aerosol base material. Thus, the aerosol substrate can be judged more accurately.

Furthermore, the atomizer and the main unit may be separately provided, and the housing 23 of the main unit may be integrated with the housing of the atomizer after the engagement by the spacer.

As can be seen from fig. 3, a bracket 31 can be added above the main circuit board 17, and the bracket 31 can be surrounded by a sealing ring 32 for fixing the battery and the main circuit board.
It should be noted that, in the embodiment of the present application, fig. 1, fig. 2 and fig. 3 may be views of the same aerosol generating device in different directions. It will be appreciated by those skilled in the art that the specific implementation and positional relationship of the air duct and the suction nozzle shown in fig. 2 and the bracket module shown in fig. 3 are not limited, and may be set as needed in actual use.
Fig. 4 shows a cross-sectional elevation view of an aerosol-generating device according to an embodiment of the application.
As shown in fig. 4, two pressure sensors, a first pressure sensor 41 and a second pressure sensor 42, respectively, may be provided in the acquisition module. A temperature sensor (not shown in fig. 4) may be provided on the left side of the first electrode contact 13 or on the right side of the second electrode contact 14.
Further, the acquisition module further comprises a second pressure sensor, wherein the second pressure sensor is arranged between the liquid storage cavity and the isolation device and is used for acquiring a second pressure parameter of the liquid storage cavity. The positions of the first pressure sensor and the second pressure sensor may be interchanged. For example, the first pressure sensor is disposed on the left side of the second pressure sensor, or the first pressure sensor is disposed on the right side of the second pressure sensor.
Further, the processing module is used for obtaining fluctuation parameters of the aerosol base material according to the first pressure parameter and the second pressure parameter, and controlling the atomizer to generate aerosol according to the fluctuation parameters. Because the first pressure sensor and the second pressure sensor are arranged at different positions at the bottom of the liquid storage cavity, the fluctuation parameters of the aerosol base material can be obtained according to the pressure values obtained by the first pressure sensor and the second pressure sensor, and the fluctuation parameters of the aerosol base material can be used for representing the fluctuation degree of the aerosol base material in the liquid storage cavity when the aerosol generating device generates displacement or inclination, so that the influence of smoke oil fluctuation on detection of the aerosol base material is further overcome, and the detection precision of the aerosol base material is improved. In addition, the first pressure sensor and the second pressure sensor may be disposed on an outer side wall of the liquid storage chamber in a vertical direction, and a relative positional relationship between the first pressure sensor and the second pressure sensor is not limited.
Due to the fact that the second pressure sensor is arranged, the host circuit board can generate an implemented density meter according to second pressure parameters measured by the second pressure sensor so as to correct a preset density meter, and therefore the density of the aerosol base material can be measured more accurately.
Fig. 5 shows a cross-sectional elevation view of an aerosol-generating device of an embodiment of the application.
As shown in fig. 5, the acquisition module may further include a tuning fork 53, a piezoelectric actuator 51, and a piezoelectric vibration pickup 52, the tuning fork being electrically connected to the piezoelectric actuator and the piezoelectric vibration pickup, respectively. In particular, the tuning fork and the piezoelectric vibration pickup may be located in the right half of fig. 5, and the piezoelectric actuator may be located in the left half of fig. 5. In addition, a temperature sensor (not shown in fig. 5) may also be provided in fig. 5.
The tuning fork body is in contact with the aerosol generating substrate and is used for generating a vibration signal. That is, the tuning fork may be immersed in the aerosol substrate of the reservoir.
Further, the piezoelectric actuator is used for enabling the tuning fork body to vibrate at a preset fixed frequency. When the density and the height of the aerosol base material are changed, the tuning fork body is affected by the current aerosol base material, so that the preset vibration frequency of the tuning fork body is changed to different degrees. Because the tuning fork body is directly and electrically connected with the piezoelectric vibration pickup, the changes of different degrees of the preset vibration frequency of the tuning fork body can be directly fed back to the piezoelectric vibration pickup. The piezoelectric vibration pickup can pick up the changes of different degrees of the preset vibration frequency of the tuning fork body, and send the changes of different degrees of the preset vibration frequency of the tuning fork body to the host circuit board for processing, so that the host circuit board judges the density of the current aerosol base material according to the changes of different degrees of the preset vibration frequency of the tuning fork body. In one example, the preset fixed frequency may enable the tuning fork to generate simple harmonic vibration according to the natural frequency of the tuning fork.
According to the embodiment of the application, the piezoelectric vibration pickup picks up the changes of different degrees of the preset vibration frequency of the tuning fork body, and the density of the aerosol base material is determined by utilizing the changes of different degrees of the preset vibration frequency of the tuning fork body, so that the density of the aerosol base material can be measured on line in real time, and the high-precision on-line measurement of the density of the aerosol base material at different temperatures can be realized.
Further, the piezoelectric actuator and the piezoelectric vibration pickup may be both disposed between the liquid storage chamber and the isolation device. The piezoelectric exciter can be electrically connected with the tuning fork body through the U-shaped circuit in the isolation device. It will be appreciated that the piezoelectric actuator and the piezoelectric vibration pickup may also be provided on the host circuit board 17, and the specific location of the piezoelectric actuator and the piezoelectric vibration pickup is not limited by the present application.
The embodiments shown in fig. 1, 4 and 5 may be combined with each other or may be used independently. That is, the acquisition module in the present application may use either one pressure sensor or two pressure sensors, or a tuning fork, a piezoelectric actuator, and a piezoelectric vibration pickup. In addition, the acquisition module in the present application may also use one pressure sensor and simultaneously use a tuning fork, a piezoelectric actuator, and a piezoelectric vibration pickup, or use two pressure sensors and simultaneously use a tuning fork, a piezoelectric actuator, and a piezoelectric vibration pickup, and then average the parameters (e.g., density) of the aerosol substrate measured separately, so as to provide accuracy in measuring the aerosol substrate.
It should be noted that, in the embodiment of the present application, the electrical connection circuit is mainly provided, and the present application is not limited to this for the air passage connection circuit after aerosol generation. In practical application, the airway communication loop can be set according to practical requirements so as to adapt to different application scenes.
