Description

Technical Field

[0001] The present application relates to the technical field of atomization devices, and in particular to an atomization device operation control method, device, computer equipment, storage medium, computer program product and atomization system. Background Art

[0002] The atomization device usually includes a battery assembly, an electronic circuit control module and an atomizer assembly, and its atomization method is mainly as follows: the battery assembly supplies power to the electronic circuit control module, and the electronic circuit control module atomizes the aerosol generating matrix to generate an aerosol by heating the resistance wire in the atomizer assembly to the atomization temperature of the aerosol generating matrix.

[0003] However, during the use of the atomizer, when the aerosol generated by high temperature is not completely used, the residual high-temperature aerosol remains in the atomizer. Due to the temperature difference between the inside and outside, the residual high-temperature aerosol liquefies to form condensate, and the condensate adheres to the inner wall of the air flow channel of the atomizer. When the user uses the aerogel generated by the atomizer again, the condensate is easily transferred to the user, making the atomizer unable to meet the needs of the user. In addition, the formed condensate may also enter other components in the atomizer, causing the sensitivity of the components to decrease or even short-circuit damage, and ultimately causing the entire product to be scrapped.

[0054] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0056] The atomization device operation control method provided in the embodiment of the present application is used to control the atomization device, specifically to control the working state of the atomization device. The method can be executed by a controller, and the controller can be arranged in the atomization device. Alternatively, the atomization device control method can also be executed by a terminal or server outside the atomization device, as long as a person skilled in the art considers it achievable.

[0057] The atomizing device includes a microphone, an output control circuit, an atomizer assembly and a power supply, and the atomizer assembly includes a heating element and an aerosol generating substrate. The aerosol generating substrate is a substrate that can release volatile compounds that can form an aerosol. The aerosol generating substrate can be solid or liquid, or include solid and liquid components.

[0058] The power supply is used to power the output control circuit. After the microphone detects the puffing action, the output control circuit supplies power to the heating element in the atomizer assembly, causing the heating element temperature to rise, thereby increasing the temperature of the aerosol generating matrix. When the temperature rises to the atomization temperature of the aerosol generating matrix, the aerosol generating matrix is ​​atomized to generate aerosol.

[0059] In one embodiment, Figure 1 As shown, a method for controlling the operation of an atomizing device is provided, which is described by taking the method executed by a controller as an example, and includes the following steps:

[0060] Step 102, obtaining the change of the airflow detection value of the suction airway of the atomization device within a preset time.

[0061] Among them, the suction airway of the atomizer device refers to the hollow channel between the microphone head of the atomizer device and the atomizer assembly, which is used to transmit airflow and aerosol, etc.

[0062] The controller can use the airflow detection device to detect the airflow in the suction airway to obtain the airflow detection value. The airflow detection device is arranged in the suction airway. Alternatively, the controller can obtain the airflow detection value of the suction airway through the microphone. The structure of the microphone is similar to that of a parallel plate capacitor. When airflow passes through, it will cause the capacitance of the microphone to change. The controller realizes the airflow detection of the suction airway based on the capacitance difference ΔC of the microphone. The capacitance C of the microphone is proportional to the dielectric constant ε of the medium, proportional to the area S of the two plates, and inversely proportional to the distance d between the two plates. When the diaphragm of the microphone vibrates due to the change of airflow, the distance d between the two plates will change Δd, so the changed capacitance ΔC = εs / (4πkΔd). The changed capacitance ΔC can be used as the airflow detection value of the suction airway. Multiple airflow detection values ​​can be ΔC1, ΔC2…ΔC in sequence. n-1 ,ΔC n .

[0063] The controller obtains the airflow detection value of the atomizing device during the suction operation multiple times within the preset time, thereby obtaining the change of the airflow detection value. The value of the preset time is not limited, and can be the entire startup time of the atomizing device, or a period of time can be selected within the startup time.

[0064] Step 104 , obtaining a change state of the suction airflow according to a change in the airflow detection value.

[0065] The controller obtains more than two airflow detection values, and according to the changing trend of the airflow detection values, the changing state of the suction airflow can be obtained. When there is a suction action at the microphone, the negative pressure in the suction airway gradually increases, and the capacitance difference △C of the microphone gradually increases. With the user's uninterrupted suction action, when the suction amplitude weakens, or when one suction is completed, the negative pressure in the suction airway will gradually decrease to the level of atmospheric pressure again, the microphone capacitance C returns to normal, and the capacitance difference △C decreases to 0. Therefore, based on the airflow detection value, the changing state of the suction airflow can be obtained.

[0066] Step 106 , if the change state of the suction airflow is that the suction airflow is weakened, the output control circuit of the atomization device is controlled to reduce the output.

[0067] The output control circuit is connected to the heating element, and is used to control the operation of the heating element of the atomization device. The heating element may be a resistance wire connected to the output control circuit. After receiving the electric energy, the heating element starts to generate heat, and the temperature rises.

[0068] After the controller receives the airflow detection value, the change state of the suction airflow can be obtained according to the airflow detection value. If the change state of the suction airflow is determined to be a weakened suction airflow, considering that the user may have completed a suction action at this time, the controller controls the output control circuit to reduce the output, thereby reducing the heating power of the heating element, so that the aerosol generated by the heating element is reduced, and the amount of aerosol remaining in the atomizer is reduced. The weakened suction action or the next suction action can also be used to take away the residual aerosol. In this way, it is possible to reduce the situation where the user produces a large amount of aerosol at the end of the suction, and the user cannot completely inhale it, thereby generating residual aerosol and gradually forming condensate. The atomizer working control method of the present application can reduce the condensate formed in the atomizer, reduce the impact of the condensate on the work of the atomizer, and help improve the working performance of the atomizer.

[0069] In the above-mentioned atomizer operation control method, after obtaining the change of the airflow detection value of the suction airway of the atomizer within a preset time, the change state of the suction airflow is obtained according to the change of the airflow detection value. If the change state of the suction airflow is that the suction airflow is weakened, the output control circuit of the atomizer is controlled to reduce the output, and the output control circuit is used to control the operation of the heating element of the atomizer. Therefore, after the suction airflow is weakened, the output control circuit is controlled to reduce the output, thereby reducing the amount of aerosol generated by the heating element. The weakened suction action or the next suction action can also be used to take away the residual aerosol, reduce the residual aerosol in the atomizer, and thus reduce the amount of condensate generated in the atomizer, which is beneficial to improve the working reliability of the atomizer.

[0070] In one embodiment, Figure 2 As shown, step 106 includes step 208 .

[0071] Step 208 : If the change state of the suction airflow is that the suction airflow is weakened, and the current airflow detection value is less than or equal to the preset threshold, the output control circuit is controlled to stop working.

[0072] The preset threshold value may be a start value of a microphone switch, or may be other values ​​set according to the personalized needs of the user.

[0073] If the change state of the inhaled airflow is that the inhaled airflow is weakened, and the current airflow detection value is less than or equal to the preset threshold value, it is considered that the user has completed the current inhalation action, and the controller controls the output control circuit to stop working and stop generating aerosol. Therefore, the weakened inhalation action or the next inhalation action can be used to a greater extent to take away more aerosol, further reducing the condensate formed by the aerosol in the atomization device.

[0074] In this embodiment, if the change state of the suction airflow is that the suction airflow is weakened, and the current airflow detection value is less than or equal to the preset threshold, the controller controls the output control circuit to stop working, which can further reduce the condensate formed by the aerosol in the atomization device.

[0075] In one embodiment, Figure 2 As shown, step 104 includes step 204 and step 206 .

[0076] Step 204, obtaining a difference between the current airflow detection value and the airflow detection value obtained by the previous sampling.

[0077] During the airflow detection process, as time goes by, the controller will obtain multiple airflow detection values, and then obtain the difference between the current airflow detection value and the airflow detection value obtained by the previous sampling, and the difference value is generally a difference. In other embodiments, the difference value can also be a ratio, etc., as long as those skilled in the art believe that it can be achieved.

[0078] Optionally, the controller is not limited to acquiring data of the airflow detection value, and can acquire the data in real time to obtain more comprehensive data, or can acquire the data at preset time intervals to reduce the workload.

[0079] Step 206: Obtain the change state of the suction airflow according to the difference value.

[0080] After the controller obtains the difference between the current airflow detection value and the airflow detection value obtained by the last sampling, it can also obtain the change state of the suction airflow. For example, if the difference between the current airflow detection value and the airflow detection value obtained by the last sampling is a difference, when the difference is greater than zero, it is judged that the suction airflow is enhanced, when the difference is less than zero, it is judged that the suction airflow is weakened, and when the difference is equal to zero, it is judged that the suction airflow has not changed. Expandably, if the difference between the current airflow detection value and the airflow detection value obtained by the last sampling is a ratio, when the difference is greater than 1, it is judged that the suction airflow is enhanced, when the difference is less than 1, it is judged that the suction airflow is weakened, and when the difference is equal to 1, it is judged that the suction airflow has not changed.

[0081] In this embodiment, by obtaining the difference between the current airflow detection value and the airflow detection value obtained by the previous sampling, and then obtaining the change state of the suction airflow according to the difference, the judgment process is simple and the judgment result is accurate.

[0082] In one embodiment, Figure 3 As shown, before step 102 , the atomization device operation control method further includes step 301 .

[0083] Step 301, determining whether an ignition start instruction is received.

[0084] If the controller receives the ignition start instruction, step 301 is executed to start airflow detection.

[0085] Among them, the start ignition instruction is used to indicate that the atomizer needs to start heating. If the start ignition instruction is received, it is considered that the atomizer needs to start heating and start the atomization work. After determining that the atomizer needs to start heating, the airflow detection is performed to realize the operation control of the atomizer, which can reduce the waste of resources caused by continuous airflow detection of the suction airway.

[0086] Further, in one embodiment, step 301 includes any one of step 302 , step 303 and step 304 .

[0087] Step 302, determining whether the starter of the atomization device has received a start ignition instruction.

[0088] If the starter receives the ignition command, the controller receives the start ignition command. The operation of receiving the start ignition command through the starter is simple.

[0089] Among them, the starter of the atomizing device can be a key switch arranged on the atomizing device, and the key switch is connected to the controller. When the user presses the key switch, the controller receives the start ignition instruction. Sending the start ignition instruction through the key switch is simple to operate. It can be understood that in other embodiments, the starter can also be other types of devices, such as a touch screen or a voice recognition device, etc., which is not limited here, as long as those skilled in the art believe that it can be implemented.

[0090] Step 303, determining whether there is airflow in the suction airway of the atomizing device.

[0091] If there is airflow in the suction airway, the controller receives the start ignition instruction. By detecting whether there is airflow in the suction airway, the detection of whether the start ignition instruction is received is realized, and the detection is sensitive and highly automated.

[0092] Specifically, the controller is connected to the microphone, and determines whether there is airflow in the suction airway of the atomizer device through the working state of the microphone. Specifically, when there is a suction action at the microphone, the airflow at the microphone changes, and the change in airflow will cause the capacitance of the microphone to change. Its capacitance C is proportional to the dielectric constant ε of the medium, proportional to the area S of the two plates, and inversely proportional to the distance d between the two plates. When the diaphragm of the microphone vibrates due to the change in airflow, the distance d between the two plates will change Δd, so the changed capacitance ΔC = εs / (4πkΔd). When the changed capacitance ΔC is greater than zero, it is considered that there is airflow in the suction airway.

[0093] Step 304 , determining whether the starter of the atomizing device has received an ignition start instruction and whether there is airflow in the suction airway of the atomizing device.

[0094] The process of determining whether the starter of the atomizing device has received the start ignition instruction and the process of determining whether there is airflow in the suction airway of the atomizing device have been described in detail above and will not be repeated here.

[0095] In this step, when the atomizer device's starter receives the start ignition command and there is airflow during the atomizer device's suction, that is, when two conditions are met, it is considered that the controller has received the start ignition command. Thus, by double-judging and confirming the receipt of the start ignition command, the occurrence of false triggering can be effectively reduced, and the working performance of the atomizer device can be improved.

[0096] like Figure 3 As shown, in one embodiment, after step 301 , the atomization device operation control method further includes step 305 .

[0097] Step 305: If the ignition start instruction is not received, the output control circuit is controlled to be in an off state.

[0098] When the start ignition command is not received, considering that the atomizer does not need to work at this time, the output control circuit is controlled to be in a shut-off state, and power supply to the heating element is stopped to reduce resource waste.

[0099] In one embodiment, Figure 4 As shown, step 102 includes step 402 .

[0100] Step 402: obtaining the change of the airflow detection value of the suction airway of the atomizing device within the preset time interval according to the preset time interval.

[0101] When the controller obtains the airflow detection value, it obtains the change of the airflow detection value of the suction airway of the atomizer device within the preset time interval to reduce the workload. The value of the preset time interval is not unique, and is generally a value of milliseconds to ensure that the amount of sampled data is sufficient.

[0102] In one embodiment, Figure 4 As shown, after step 104 , the atomization device operation control method further includes step 406 .

[0103] Step 406 , if the change state of the suction airflow is that the suction airflow remains unchanged or increases, the output control circuit of the atomization device is controlled to output according to a preset working state.

[0104] The preset working state may be a working state selected by a user, or a state matched according to a startup time, etc.

[0105] If the change state of the suction airflow is that the suction airflow remains unchanged, it is considered that the current suction action has ended, and the control output control circuit outputs according to the preset working state, so that the atomization effect of the atomization device can better meet the user's needs.

[0106] If the change state of the inhaled airflow is that the inhaled airflow is enhanced, it is considered that the user needs aerosol, and the output control circuit of the atomization device is controlled to output according to the preset working state to meet the user's needs.

[0107] In this embodiment, if the change state of the suction airflow is that the suction airflow remains unchanged or increases, the output control circuit of the atomization device is controlled to output according to the preset working state, so that the working state of the atomization device is more in line with the actual needs of the user.

[0108] In one embodiment, an atomization system is provided, including an atomization device and a controller, wherein the controller is used to control the operation of the atomization device according to the method in the above embodiment.

[0109] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. Figure 5 As shown, the atomization system includes a controller ① and an atomization device, and the atomization device includes a microphone ②, an output control circuit ④, a power supply ③ and an atomizer assembly. The microphone ② can be used as an airflow detection component, and the atomizer assembly includes a heating element and an aerosol generating matrix, and the heating element is a resistance wire RL.

[0110] The power supply ③ is used to supply power to the output control circuit ④. After the microphone ② detects the inhalation action, the output control circuit ④ supplies power to the resistance wire RL in the atomizer assembly, causing the temperature of the resistance wire RL to begin to rise, thereby increasing the temperature of the aerosol generation matrix. After the temperature rises to the atomization temperature of the aerosol generation matrix, the aerosol generation matrix is ​​atomized to generate aerosol.

[0111] The controller executing the atomization device working control method in the embodiment of the present application is used as an example for explanation. The controller can be an MCU control module, and the airflow detection component detects the change in the airflow during the user's inhalation process and transmits the information to the MCU control module. The MCU control module processes the information and outputs a control signal to control the output control circuit to adjust the output voltage or power of the output control circuit, and the power supply module is used to supply power to the entire circuit system.

[0112] The specific airflow detection and control logic of the atomizer working control method is as follows: the airflow detection component detects the airflow changes in the suction airway in real time. When the user inhales, the airway negative pressure gradually increases, and the microphone capacitance difference △C gradually increases. As the user inhales continuously, the airway negative pressure will gradually decrease to the level of atmospheric pressure again, the microphone capacitance C returns to the normal value, and the capacitance difference △C decreases to 0. The airflow detection component transmits the capacitance information to the MCU control module in real time. The MCU control module captures and determines in real time when the user's suction weakens and the capacitance begins to decrease. The MCU control module controls the output control circuit in advance to reduce the output voltage or output power. When the user's suction force weakens to a certain level (the user's remaining suction force can only completely absorb the aerosol generated previously to ensure that there is no residual aerosol in the atomizer), that is, the negative pressure of the suction airway decreases, and the microphone capacitance difference △C reaches the preset threshold, the MCU control module will directly shut off the output of the output control circuit to ensure that the user's suction effect is improved and the residual aerosol can be completely absorbed, avoiding the user's generation of a large amount of aerosol at the end of the suction, and the user cannot completely absorb it, so that the residual aerosol gradually forms condensate.

[0113] It should be noted that the microphone head can be an air microphone. The structure of an air microphone is similar to a parallel plate capacitor. When air flows through it, it will cause a change in capacitance. The MCU control module mainly determines the change in its capacitance difference ΔC and then controls the output. The capacitance C of the air microphone is proportional to the dielectric constant ε of the medium, proportional to the area S of the two plates, and inversely proportional to the distance d between the two plates. When the diaphragm of the air microphone vibrates due to changes in airflow, the distance d between the two plates will change Δd, so the changed capacitance ΔC = εs / (4πkΔd). Among them, ΔC1, ΔC2…ΔC n-1 ,ΔC n It is the airflow detection value obtained during the start-up airflow detection process.

[0114] The specific process of the atomization device working control method includes: after the functional modules of the atomization system are connected normally, the atomization system is powered on. The MCU control module detects in real time whether the microphone has a suction action or whether the key switch is pressed to start the ignition output. If the ignition output is started, the MCU control module starts the ADC detection to obtain the suction airflow detection value ΔC obtained by the airflow detection component. If the obtained airflow detection value ΔC is zero, it means that the user has not performed a suction action, then the MCU control module controls the output control circuit to directly shut down the output, and the ignition work is judged as follows. Figure 6 When the airflow detection value ΔC obtained by the ADC is greater than zero, the MCU control module executes the airflow detection algorithm, first converting the airflow detection values ​​ΔC1, ΔC2…ΔC obtained at regular intervals. n Store them into the register in sequence and compare and judge the detected values ​​ΔC simultaneously n <ΔC n-1If the judgment execution is true, it means that the user's inhalation airflow begins to weaken, and the MCU control module can control the output control circuit to reduce the output adjustment (the reduction standard can refer to the output mode, and the output is reduced by a certain proportion of the output value, and the proportion of 10% is used here), and when ΔC n When it is equal to the threshold ΔC0 (the threshold can be set according to the user's actual puffing experience, and the start value of the microphone switch is used here), the MCU control module will control the output control circuit to turn off the output, so as to ensure that all the aerosol generated by the atomizer is sucked away, and prevent the aerosol from condensing and liquefying to produce condensate remaining in the wall of the suction airway. n <ΔC n-1 If the judgment is false, it means that the user has enough suction airflow to draw away the aerosol. At this time, the output value (voltage or power) is the user-set value and is output as a fixed value. The airflow detection algorithm process is as follows Figure 7 shown.

[0115] The atomizer working control method provided by the present application, from the perspective of electric control, prevents the generation of condensate through circuit design, and effectively improves the working performance. From the perspective of the generation of condensate, it solves the problem of condensate being misused by users, solves the problem of oil frying, solves the problem of condensate damaging the circuit, and solves the problem of button mis-triggering. The atomizer working control method optimizes the output temperature rise curve, effectively improves the output consistency, and can effectively reduce the odor caused by excessive heating of the aerosol generating matrix. In addition, it effectively prevents the generation of condensate, and solves the condensate problem of the atomizer from the direction of electric control. When the aerosol generating matrix cannot penetrate into the cotton core in time when the aerosol is sucked for a long time, it will cause the inside of the cotton core to burn, that is, dry burning. The atomizer working control method of the present application reduces the output by controlling the output control circuit, which has a certain protective effect on preventing dry burning. It can also effectively prevent the condensate from entering the battery through the airway, causing the airflow sensor to decrease in sensitivity or even short-circuit damage, or causing damage to other components and short-circuit of the circuit board, effectively solving the problem of button mis-triggering, simple structure, simple and convenient assembly.
