[0002] An electronic atomization device is disclosed in the prior art. The electronic atomization device is generally composed of an airflow sensor (such as a microphone, a silicon microphone, etc.), a heating element, a battery, a control circuit and the like. At present, the start and stop of the heating element in many electronic atomization devices are usually controlled according to the detection result of the airflow sensor, that is, when the airflow sensor detects inhalation, the heating element starts and generates heat normally; when the airflow sensor detects that the inhalation stops, the heating element stops working.

[0003] However, the control method of the prior art will result in that after the puffing is completed, part of the aerosol (i.e., the atomized atomized matrix) is not aspirated, and thus remains in the airway of the electronic atomization device and re-condenses into the atomized matrix.

[0072] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0073] In one embodiment, an electronic atomization device is provided, such as Figure 1 As shown, the electronic atomization device includes:

[0074] The processing module 120, the power module 110, the heating element 130 and the air pressure sensor 140, an airway (not shown) is formed in the electronic atomization device, and the airway is for aerosol to pass through; the air pressure sensor 140 is used to detect the air pressure value in the airway. Among them, the processing module may include one or more processing cores. The processing module uses various interfaces and lines to connect the various parts of the entire electronic atomization device, and executes various functions and processes data of the electronic atomization device by running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory. Optionally, the processing module can be implemented in at least one hardware form of digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA).

[0075] The power module includes a battery or a battery cell for storing electric energy. The heating element may include a liquid guide and a heating film attached to the liquid guide. By outputting power to the heating film, the heating film can be heated to atomize the aerosol atomization matrix transmitted by the liquid guide. The heating film can also be heated to atomize the aerosol atomization matrix transmitted by the liquid guide by outputting temperature to the heating film.

[0076] The power module 110 is used to provide energy to the heating element 130 , the air pressure sensor 140 and the processing module 120 respectively, so that the processing module 120 , the heating element 130 and the air pressure sensor 140 can work normally.

[0077] As an embodiment, the power module 110 can be connected to the processing module 120 and the heating element 130 respectively, and the processing module 120 can send a control instruction to the power module 110 to control the output power of the power module 110 to the heating element 130. As another embodiment, the power module 110, the processing module 120 and the heating element 130 can be connected in sequence, and the processing module 120 can control the on-off between the processing module 120 and the heating element 130 by realizing its own on-off, so as to realize the control of the output power of the power module 120 to the heating element 130.

[0078] The processing module 120 may also send a control instruction to the power module 110 to control the output temperature of the power module 110 to the heating element 130. As another embodiment, the power module 110, the processing module 120 and the heating element 130 may be connected in sequence, and the processing module 120 may control the on-off between the processing module 120 and the heating element 130 by realizing its own on-off, thereby realizing the control of the output temperature of the power module 120 to the heating element 130.

[0079] The processing module 120 is used to obtain the air pressure value detected by the air pressure sensor 140, and control the power supply module 110 to provide energy to the heating element 130 according to a first preset power within a first time period after the air pressure value is less than or equal to a preset starting air pressure, and control the power supply module 110 to provide energy to the heating element according to a second preset power corresponding to the interval in which the air pressure value is located within a second time period after the first time period; wherein the second preset power is less than the first preset power.

[0080] The processing module 120 can also be used to obtain the air pressure value detected by the air pressure sensor 140, and control the power module 110 to provide energy to the heating element 130 at a first preset temperature within a first time period after the air pressure value is less than or equal to a preset starting air pressure, and control the power module 110 to provide energy to the heating element at a second preset temperature corresponding to the interval in a second time period after the first time period according to the interval in which the air pressure value is located; wherein the second preset temperature is lower than the first preset temperature.

[0081] Specifically, the user of the electronic atomization device can inhale through the suction nozzle, so that the gas in the airway is inhaled into the user's mouth, and the air pressure sensor 140 located in the airway detects the air pressure in the airway, obtains the air pressure value in the airway, and then actively sends the obtained air pressure value to the processing module 120. Of course, the processing module 120 can also actively obtain the air pressure value detected by the air pressure sensor 140 from the air pressure sensor 140.

[0082] The processing module 120 can sense the change in air pressure in the airway according to the obtained air pressure value. At the beginning of the inhalation, the processing module 120 controls the power module 110 to provide energy to the heating element 130 according to the received air pressure value, so that the heating element 130 starts and works normally for the first time. It should be noted that the working state of the heating element 130 in the first time can refer to the prior art. The first preset power provided by the power module 110 to the heating element 130 in the first time period is generally greater than or equal to the power corresponding to the minimum atomization temperature of the atomization matrix in the electronic atomization device. The first preset temperature provided by the power module 110 to the heating element 130 in the first time period is generally greater than or equal to the minimum atomization temperature of the atomization matrix in the electronic atomization device.

[0083] In a second time period after the first time period, the processing module 120 determines the interval of the current air pressure value according to the real-time air pressure value transmitted by the air pressure sensor 140, and then determines the corresponding second preset power according to the interval, and finally controls the power supply module 110 to provide energy to the heating element 130 according to the second preset power, and the second preset power is less than the first preset power.

[0084] In the second time period after the first time period, the processing module 120 can also determine the interval of the current air pressure value according to the real-time air pressure value transmitted by the air pressure sensor 140, and then determine the corresponding second preset temperature according to the interval, and finally control the power supply module 110 to provide energy to the heating element 130 according to the second preset temperature, and the second preset temperature is lower than the first preset temperature.

[0085] For a better understanding of this application, please also refer to Figure 2 and Figure 3 , Figure 2 The middle curve is a schematic diagram of the air pressure change curve detected by the air pressure sensor in the airway. In the first time period (t1), the power module 110 provides energy to the heating element 130 according to the first preset power, so that the heating element works normally and the atomization amount is guaranteed. After the first time period (t1), the user's inhalation is close to the end. At this time, the user's inhalation requires less atomization amount, so a smaller second preset power is used to provide energy to the heating element 130, so that the aerosol in the airway is completely inhaled as much as possible, thereby reducing the residual aerosol in the airway. It should be noted that in this embodiment, only one interval corresponding to the air pressure value is set, so the second preset power is only one. In the specific implementation, multiple intervals corresponding to the air pressure value can be set, and the corresponding second preset powers can also be multiple. Multiple preset powers can be reduced in sequence according to time.

[0086] Figure 3 The middle curve is a schematic diagram of the air pressure change curve detected by the air pressure sensor in the airway. In the first time period (t1), the power module 110 provides energy to the heating element 130 according to the first preset temperature, so that the heating element works normally and the atomization amount is guaranteed. After the first time period (t1), the user's inhalation is close to the end. At this time, the amount of atomization required by the user's inhalation is small, so a smaller second preset temperature is used to provide energy to the heating element 130, so that the aerosol in the airway is completely inhaled as much as possible, thereby reducing the residual aerosol in the airway. It should be noted that in this embodiment, only one interval corresponding to the air pressure value is set, so the second preset temperature is only one. In the specific implementation, multiple intervals corresponding to the air pressure value can be set, and the corresponding second preset temperatures can also be multiple. Multiple preset temperatures can be lowered in sequence according to time.

[0087] At the same time, the sum of the first time and the second time is equal to the current time of the electronic atomization device being inhaled. In a specific implementation, the sum of the first time and the second time can also be less than the current time of the electronic atomization device being inhaled. Reducing the atomization time can also achieve the purpose of minimizing the residual aerosol in the airway.

[0088] The electronic atomization device includes: a processing module, a power supply module, a heating element and an air pressure sensor, wherein an airway is formed in the electronic atomization device; the air pressure sensor is used to detect the air pressure value in the airway; the processing module is used to obtain the air pressure value detected by the air pressure sensor, and control the power supply module to provide energy to the heating element according to a first preset power or a first preset temperature within a first time period after the air pressure value is less than or equal to a preset starting pressure, and control the power supply module to provide energy to the heating element according to a second preset power or a second preset temperature corresponding to the interval within a second time period after the first time period according to the interval in which the air pressure value is located; wherein the second preset power is less than or equal to the first preset power, and the second preset temperature is less than the first preset temperature. Through the above method, the present application first obtains the air pressure value in the airway, and then controls the power supply module to use the first preset power or the first preset temperature to provide energy to the heating element within the first time of startup, so that the heating element works normally, and then according to the range of the air pressure value, that is, according to the suction situation, a second preset power smaller than the first preset power is used to control the power supply module to provide energy to the heating element, or a second preset temperature smaller than the first preset temperature is used to control the power supply module to provide energy to the heating element, thereby reducing the generation of aerosols, and then reducing the aerosols in the airway.

[0089] As an embodiment, the first part of the air pressure sensor 140 is arranged in the airway, and the second part is arranged on the electronic atomization device; the first part is used to detect the first air pressure in the airway; the second part is used to detect the second air pressure; the air pressure sensor 140 is also used to obtain the air pressure value in the airway based on the first air pressure and the second air pressure.

[0090] Specifically, in this embodiment, the air pressure sensor 140 includes two parts, the first part is arranged in the airway, and the second part is arranged on the electronic atomization device. The specific position of the second part can be set according to the actual situation, for example: it can be set on the shell of the electronic atomization device; set in the shell of the electronic atomization device; or set in the battery compartment of the electronic atomization device, etc. It only needs not to be set in the airway. Then the air pressure sensor 140 uses the difference between the second air pressure and the first air pressure as the air pressure value in the airway.

[0091] As another embodiment, the air pressure sensor 140 may also only include a portion disposed in the airway. In this case, the processing module 120 may use the difference between the pre-stored ambient air pressure and the air pressure detected by the air pressure sensor 140 as the air pressure value in the airway. Of course, this method is relative to the previous method in that the accuracy of the air pressure value becomes lower. When the electronic atomization device is used in different locations, the ambient air pressure is different, which may cause the control accuracy to become lower. In this case, a position sensor may be added to the electronic atomization device, and the ambient air pressure at the current location may be determined by querying the position information obtained by the position sensor, thereby improving the accuracy. Of course, in the specific implementation, the electronic atomization device may also communicate with other electronic devices to obtain the ambient air pressure at the current location, which is not limited here.

[0092] As an embodiment, in the process of a single puff, the user generally requires a relatively large amount of aerosol in the first half of the time, so the first time is greater than more than half of the preset single puff time, thereby ensuring the amount of atomization in the early stage. It is understandable that the first time can be set accordingly according to the different users of the electronic atomization device. For example, the first time is 1 / 2, or 1 / 3 of the total time of the user's previous puff, or 1 / 2, or 1 / 3 of the single puff time obtained according to the historical record of the electronic atomization device being puffed, etc. The single puff time can be obtained by using a deep learning algorithm based on the historical record of the electronic atomization device being puffed, or the average value of each puff is obtained based on the historical record of the electronic atomization device being puffed. According to the above description, it can be understood that the single puff time refers to the time from the user starting to end the puff of the electronic atomization device, that is, the time of each puff, or the time of each puff obtained according to the historical puff record.

[0093] As an embodiment, the preset power is adjusted in real time according to the preset temperature, that is, the first preset power is adjusted in real time according to the first preset temperature, and the second preset power is adjusted in real time according to the second preset temperature. Specifically, the first preset power / the second preset power can increase / decrease with the increase / decrease of the first preset temperature / the second preset temperature, and can be adjusted according to actual conditions.

[0094] As an example, Figure 4 As shown, the second preset power includes a first sub-power and a second sub-power, and the processing module 120 is used to: when the air pressure value is in the first interval, control the power module 110 to provide energy to the heating element 130 according to the first sub-power corresponding to the first interval; when the air pressure value is in the second interval, control the power module 110 to provide energy to the heating element 130 according to the second sub-power corresponding to the second interval; wherein the maximum air pressure value of the first interval is less than the minimum air pressure value of the second interval, and the first sub-power is greater than the second sub-power.

[0095] Specifically, as an embodiment, the second preset power includes 2 power values. Specifically, the second preset power includes a first sub-power and a second sub-power. The first interval is [P2, P1], and the second interval is (P2, Pstop]. The first sub-power corresponds to the first interval, and the second sub-power corresponds to the second interval. The maximum air pressure value in the first interval is less than the minimum air pressure value in the second interval, and the corresponding first sub-power is greater than the second sub-power (since the air pressure value in the airway is a negative value during the suction process, the smaller the air pressure value, the greater the corresponding power). In the specific implementation, the second preset power may include multiple, and the corresponding intervals may also be multiple.

[0096] During the suction process, after the first time, the air pressure value in the airway will gradually increase within the second time. When the air pressure value is in the first interval, the control power module 110 provides energy to the heating element 130 according to the first sub-power; when the air pressure value is in the second interval, the control power module 110 provides energy to the heating element 130 according to the second sub-power. As an embodiment, the maximum air pressure value P2 of the first interval is 2 / 3 to 1 / 2 of the stop air pressure (Pstop) corresponding to the stopping of the heating element, the first sub-power is 2 / 3 to 1 / 3 of the first preset power, and the second sub-power is 2 / 5 to 1 / 5 of the first preset power.

[0097] As an example, Figure 5 As shown, the second preset temperature includes a first sub-temperature and a second sub-temperature, and the processing module 120 is used to: when the air pressure value is in the first interval, control the power module 110 to provide energy to the heating element 130 according to the first sub-temperature corresponding to the first interval; when the air pressure value is in the second interval, control the power module 110 to provide energy to the heating element 130 according to the second sub-temperature corresponding to the second interval; wherein the maximum air pressure value of the first interval is less than the minimum air pressure value of the second interval, and the first sub-temperature is greater than the second sub-temperature.

[0098] Specifically, as an embodiment, the second preset temperature includes 2 temperature values. Specifically, the second preset temperature includes a first sub-temperature and a second sub-temperature. The first interval is [P2, P1], and the second interval is (P2, Pstop]. The first sub-temperature corresponds to the first interval, and the second sub-temperature corresponds to the second interval. The maximum air pressure value in the first interval is less than the minimum air pressure value in the second interval, and the corresponding first sub-temperature is greater than the second sub-temperature (since the air pressure value in the airway is a negative value during the suction process, the smaller the air pressure value, the higher the corresponding temperature). In the specific implementation, the second preset temperature may include multiple values, and the corresponding intervals may also be multiple values.

[0099] During the inhalation process, after the first time, the air pressure value in the airway will gradually increase within the second time. When the air pressure value is in the first interval, the control power module 110 provides energy to the heating element 130 according to the first sub-temperature; when the air pressure value is in the second interval, the control power module 110 provides energy to the heating element 130 according to the second sub-temperature. As an embodiment, the maximum air pressure value P2 of the first interval is 2 / 3 to 1 / 2 of the stop air pressure (Pstop) corresponding to the stop of the heating element, the first sub-temperature is lower than the preset temperature threshold, and the second sub-temperature is 1 / 2 of the preset temperature threshold, wherein the preset temperature threshold can be set to the atomization boiling point, and can also be set to other values ​​according to actual application conditions.

[0100] As an example, Figure 6 As shown, the processing module 120 is further used for:

[0101] In the second time, if the air pressure value is in the third interval, controlling the power module 110 to provide energy to the heating element according to the first sub-power;

[0102] The maximum air pressure value in the third interval is smaller than the minimum air pressure value in the first interval.

[0103] Specifically, during the suction process, the following may occur: Figure 6 In the situation shown, the air pressure in the airway has multiple sections of high negative pressure, that is, the user has a large suction force during multiple suctions in one suction process. Therefore, in order to ensure the amount of atomization (amount of aerosol), a third interval is also set in the second time period. The maximum air pressure value of the third interval is less than the minimum air pressure value of the first interval. As an embodiment, the maximum air pressure value of the third interval is 3 to 5 times the stop air pressure corresponding to the stop of the heating element. The specific setting can be based on actual conditions. If the air pressure value appears in the third interval within the second time, it means that the demand for aerosol is large, so the processing module 120 controls the power module 110 to provide energy to the heating element 130 according to the first sub-power.

[0104] As an example, Figure 7 As shown, the processing module 120 is further used for:

[0105] In the second time, if the air pressure value is in the third interval, controlling the power module 110 to provide energy to the heating element according to the first sub-temperature;

[0106] The maximum air pressure value in the third interval is smaller than the minimum air pressure value in the first interval.

[0107] Specifically, during the suction process, the following may occur: Figure 7In the situation shown, the air pressure in the airway has multiple high negative pressures, that is, the user has a large suction force during multiple suctions in one suction process. Therefore, in order to ensure the amount of atomization (amount of aerosol), a third interval is also set in the second time period. The maximum air pressure value of the third interval is less than the minimum air pressure value of the first interval. As an embodiment, the maximum air pressure value of the third interval is 3 to 5 times the stop air pressure corresponding to the stop of the heating element. The specific setting can be based on actual conditions. If the air pressure value appears in the third interval within the second time, it means that the demand for aerosol is large, so the processing module 120 controls the power module 110 to provide energy to the heating element 130 according to the first sub-temperature.

[0108] As an example, Figure 8 As shown, the air pressure value (i.e., negative pressure value) in the airway can be divided into multiple types. For example, based on statistics of historical data, the negative pressure value is divided into 3 intervals, that is, the negative pressure type is divided into 3 types, the negative pressure value less than 500Pa is the first type, the negative pressure value greater than 500Pa and less than 1000Pa is the second type, and the negative pressure value greater than 1000Pa is the third type. The air pressure value in the airway of the electronic atomization device is detected by the air pressure sensor 140, and whether the electronic atomization device is started (i.e., whether the heating element 130 is heating) is determined according to the air pressure value. Within the first time (T1) when the electronic atomization device is started, the power module 110 is controlled to provide energy to the heating element 130 according to the first preset power. Within the second time after the first time period, the interval of the air pressure value is determined, that is, it is determined to which category the air pressure value belongs. If it belongs to the first category, the second sub-power control power module 110 corresponding to the first category is used to provide energy. If it belongs to the second category, the first sub-power control power module 110 corresponding to the second category is used to provide energy. If it belongs to the third category, the first preset power control power module 110 corresponding to the third category is used to provide energy.

[0109] As an example, Fig. 9As shown, the air pressure value (i.e., negative pressure value) in the airway can be divided into multiple types. For example, based on statistics of historical data, the negative pressure value is divided into 3 intervals, that is, the negative pressure type is divided into 3 types, the negative pressure value less than 500Pa is the first type, the negative pressure value greater than 500Pa and less than 1000Pa is the second type, and the negative pressure value greater than 1000Pa is the third type. The air pressure value in the airway of the electronic atomization device is detected by the air pressure sensor 140, and whether the electronic atomization device is started (i.e., whether the heating element 130 is heating) is determined according to the air pressure value. Within the first time (T1) when the electronic atomization device is started, the power module 110 is controlled to provide energy to the heating element 130 at a first preset temperature. Within a second time after the first time period, the interval in which the air pressure value is located is determined, that is, it is determined to which category the air pressure value belongs. If it belongs to the first category, the second sub-temperature control power module 110 corresponding to the first category is used to provide energy. If it belongs to the second category, the first sub-temperature control power module 110 corresponding to the second category is used to provide energy. If it belongs to the third category, the first preset temperature control power module 110 corresponding to the third category is used to provide energy.

[0110] In the above embodiment, since the negative pressure value is fixed, the maximum air pressure value (P2) and the minimum air pressure value (P1) of the first interval are naturally fixed. Although it is relatively easy to implement, more test data is required to determine the more suitable minimum air pressure value (P1) and maximum air pressure value (P2). Therefore, in this embodiment, the minimum air pressure value (P1) and the maximum air pressure value (P2) of the first interval are determined by calculating the average air pressure value and the minimum air pressure value in the first time period (T1), that is, the average air pressure value P2 in the first time period (T1) is taken. mean , and obtain the minimum pressure P in real time min .

[0111] As an example, the calculation formulas for the minimum air pressure value (P1) and the maximum air pressure value (P2) may be:

[0112] P1=P mean *level*weight+P min *(1-weight)

[0113] P2=1 / 2*P1

[0114] Among them, level is the reduction scale, weight is the preset weight value, the value of weight can be adjusted appropriately according to different situations, level*weight is the average pressure P mean The corresponding weight coefficient, 1-weight is the minimum pressure P min The corresponding weight coefficient. The air pressure thresholds for light and heavy suction can be preset.mean When the pressure is greater than or equal to the critical value, it means that it is a light suction and P can be increased appropriately. min to take into account the possibility of heavy smoking later. mean With P min When the difference is greater than the threshold value under normal fluctuation, it means that the fluctuation is large at this time, so P is increased in real time. min The weight coefficient ensures that the maximum pressure value (P2) and the minimum pressure value (P1) of the first interval have better real-time performance. mean Less than the critical pressure value and P mean With P min When the difference is less than the threshold value under normal fluctuation, it means that it is severe suction, but the fluctuation is not large, P min The weight coefficient can be appropriately reduced to ensure the stability of the maximum air pressure value (P2) and the minimum air pressure value (P1).

[0115] In this embodiment, the maximum pressure value (P2) and the minimum pressure value (P1) of the first interval are changing at all times, that is, the average pressure value P mean The minimum pressure P is also considered. min ,By adjusting the weight coefficients of the two, the false trigger rate of light draw is reduced, and the calculation efficiency and the validity of the calculation results are improved.
