[0002] The working principle of the electronic atomizer is mainly to heat and evaporate the atomization medium into aerosol by atomization and electric heating, which is inhaled by the consumer, so as to achieve the experience of smoking. In this process, once the atomization medium is reduced to the extent that it cannot supply the heating body in time, the heating body will be in a dry burning state. On the one hand, it seriously reduces the experience of the consumer, and on the other hand, high-temperature dry burning will produce harmful gases or damage the electronic atomizer, affecting the health of the consumer. Therefore, the function of preventing dry burning of the atomizer has become a popular research field.

[0044] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0045] In one embodiment, an electronic atomizer is provided, such as Figure 1 As shown, the electronic atomizer includes:

[0046] The power module 110, the control module 120, the heating element 130 and the detection module 140,

[0047] The power module 110 is connected to the control module 120 and the detection module 140 . The control module 120 is also connected to the heating element 130 and the detection module 140 .

[0048] The power module 110 can provide energy to the heating element 130, causing the heating element 130 to operate. The control module 120 is used to control the energy provided by the power module 110 to the heating element 130 to control the power of the heating element 130. The detection module 140 is used to detect the operating status of each module in the electronic atomizer, which may specifically include detecting the temperature of the heating element 130, the output voltage / output power of the power module 110, etc. The detection module 140 can transmit the real-time detection of the operating status of each module in the electronic atomizer to the control module 120. The control module 120 controls the operating status of the electronic atomizer based on the obtained status.

[0049] Specifically, two parameters are set in this embodiment, namely the first parameter and the second parameter. The states of the electronic atomizer in this application include: normal oil supply state, oil shortage state and dry burning state. The control module 120 is used to reduce the energy provided by the power module 110 to the heating element 130 when the operating parameter reaches the first parameter, and control the operating parameter to be maintained at the first parameter; the control module 120 is also used to control the power module 110 to stop energy output when the operating parameter reaches the second parameter. The control module 120 is also used to determine that the electronic atomizer is in an oil shortage state when the temperature of the heating element 130 is maintained at the first parameter.

[0050] In one embodiment, the first parameter is a first temperature, the second parameter is a second temperature, and the second temperature is greater than the first temperature. It should be noted that the first temperature is higher than the optimal atomization temperature of the atomizing medium in the electronic atomizer. For ease of understanding, taking the atomizing medium as glycerol (VG) as an example, the optimal atomization temperature of glycerol is 210±20 degrees Celsius, then the first temperature is 230±20 degrees Celsius, which is equivalent to the first temperature being 20 degrees Celsius higher than the optimal atomization temperature of the atomizing medium. It can also be understood that the first temperature is slightly higher than the optimal atomization temperature of the atomizing medium. It can be understood that the difference in atomizing medium will cause its optimal atomization temperature to change accordingly, and the first temperature will also change accordingly.

[0051] When the first parameter is the first temperature and the second parameter is the second temperature, the control module 120 is specifically used to determine that the electronic atomizer is in a normal oil supply state if the temperature of the heating element 130 is between the optimal atomization temperature of the atomizing medium in the electronic atomizer and the first temperature, and the first temperature is greater than the optimal atomization temperature of the atomizing medium in the electronic atomizer.

[0052] Specifically, during normal use, see Figure 2 At time t1, the electronic atomizer is started, that is, at time t1, the power module 110 outputs corresponding energy to the heating element 130. The heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. At time t2, the user stops inhaling, and the temperature of the heating element 130 can drop to room temperature or be maintained at a fixed preheating temperature (this temperature is lower than the optimal atomization temperature of the atomizing medium, for example, maintained at a temperature for preheating the atomizing medium). The detection module 140 obtains the temperature of the heating element 130 in real time. If the temperature of the heating element 130 is between the optimal atomization temperature and the first temperature, it is determined that the electronic atomizer is in a normal oil supply state at this time.

[0053] As another example, the control module 120 is configured to reduce the energy provided by the power module 110 to the heating element 130 after the temperature of the heating element 130 reaches the first temperature, so as to control the heating element 130 to maintain the first temperature.

[0054] Specifically, during normal use, see Figure 3, time t1 is the start-up, that is, the electronic atomizer starts at time t1, the power module 110 outputs corresponding energy to the heating element 130, the heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. If at time t3, the control module 120 obtains the detection module 140 to detect in real time that the temperature of the heating element 130 reaches the first temperature. At this time, it means that there is less atomizing medium in the electronic atomizer, that is, the electronic atomizer is in an oil-deficient state. In order to avoid the temperature of the heating element 130 from continuing to rise, and for normal use by the user (the temperature of the heating element 130 is slightly higher than the optimal atomizing temperature of the atomizing medium, which basically does not affect the atomization effect or the impact is small). From time t3, the control module 120 controls the power module 110 to reduce the corresponding energy output to the heating element 130 (the curve of reducing the output energy is as shown in FIG. Figure 3 From time t3 to time t4 (shown in FIG. 1 ), the heating element 130 is maintained at the first temperature.

[0055] As another example, the control module 120 is further configured to control the power module 110 to stop outputting energy if the temperature of the heating element reaches a second temperature during the process of reducing the energy provided by the power module to the heating element.

[0056] Specifically, during normal use, see Figure 4 , time t1 is the start-up, that is, the electronic atomizer starts at time t1, the power module 110 outputs corresponding energy to the heating element 130, the heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. If at time t5, the control module 120 obtains the detection module 140 to detect in real time that the temperature of the heating element 130 reaches the first temperature. At this time, it means that there is less atomizing medium in the electronic atomizer, that is, the electronic atomizer is in an oil-deficient state. In order to avoid the temperature of the heating element 130 from continuing to rise, and for normal use by the user (the temperature of the heating element 130 is slightly higher than the optimal atomizing temperature of the atomizing medium, which basically does not affect the atomization effect or the impact is small). From time t5, the control module 120 controls the power module 110 to reduce the corresponding energy output to the heating element 130 (the curve of reducing the output energy is as shown in FIG. Figure 4 If the energy output to the heating element 130 is reduced, but the temperature of the heating element 130 still rises (the atomizing medium substantially does not enter or cannot enter the atomizing chamber of the electronic atomizer), it is determined that the electronic atomizer is in or is about to enter a dry-burn state, and the power module 110 is controlled to stop energy output, thereby preventing the electronic atomizer from dry-burning.

[0057] In another embodiment, the first parameter includes a first temperature, and the second parameter includes an output voltage / output power; the control module 120 is configured to reduce the energy provided by the power module 110 to the heating element 130 after the temperature of the heating element 130 reaches the first temperature, so as to control the heating element 130 to maintain the first temperature. Figure 3 And the corresponding explanations will not be repeated here.

[0058] The control module 120 is also used to determine whether the output voltage / output power of the power module 110 is reduced to the lower limit of the corresponding working threshold in the process of reducing the energy provided by the power module 100 to the heating element 130; if the output voltage / output power of the power module 110 is reduced to the lower limit of the corresponding working threshold, it is determined that the electronic atomizer is in or is about to be in a dry-burning state, and the power module 110 is controlled to stop energy output, thereby avoiding dry-burning of the electronic atomizer.

[0059] Specifically, during normal use, refer to Figure 4 , time t1 is the start-up, that is, the electronic atomizer starts at time t1, the power module 110 outputs corresponding energy to the heating element 130, the heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. If at time t5, the control module 120 obtains the detection module 140 to detect in real time that the temperature of the heating element 130 reaches the first temperature. At this time, it means that there is less atomizing medium in the electronic atomizer, that is, the electronic atomizer is in an oil-deficient state. In order to avoid the temperature of the heating element 130 from continuing to rise, and for normal use by the user (the temperature of the heating element 130 is slightly higher than the optimal atomizing temperature of the atomizing medium, which basically does not affect the atomization effect or the impact is small). From time t5, the control module 120 controls the power module 110 to reduce the corresponding energy output to the heating element 130 (the curve of reducing the output energy is as shown in FIG. Figure 4 (as shown from time t5 to time t6 in the figure). At this point, the control module 120 can obtain the output voltage / output power of the power module 110. If the temperature of the heating element 130 continues to rise while the corresponding energy output to the heating element 130 continues to decrease, the control module 120 can also determine whether the output voltage / output power of the power module 110 has dropped to the lower limit of the corresponding operating threshold. If the output voltage / output power of the power module 110 has dropped to the lower limit of the corresponding operating threshold, and the temperature of the heating element 130 continues to rise, it is determined that the electronic atomizer is in or is about to enter a dry-burn state, and the power module 110 is controlled to stop energy output, thereby preventing the electronic atomizer from dry-burning.

[0060] Among them, the lower limit of the working threshold includes the output voltage lower limit / output power lower limit. Exemplarily, the output voltage lower limit / output power lower limit is any value between 10% and 40% of the maximum output voltage / maximum output power, that is, the output voltage lower limit is any value between 10% and 40% of the maximum output voltage; the output power lower limit is any value between 10% and 40% of the maximum output power.

[0061] The above-mentioned electronic atomizer includes: a power module, a control module, a heating element and a detection module; the power module is used to provide energy to the heating element; the detection module is used to detect the operating parameters of the electronic atomizer; the control module is used to reduce the energy provided by the power module to the heating element when the operating parameter reaches a first parameter, and control the operating parameter to be maintained at the first parameter; the control module is also used to control the power module to stop energy output when the operating parameter reaches a second parameter. Through the above method, the present application sets two parameters, namely the first parameter and the second parameter. When the operating parameter of the electronic atomizer reaches the first parameter, the energy provided by the power module to the heating element is reduced to control the heating element to be maintained at the first parameter; if the energy provided by the power module to the heating element is reduced, the operating parameter of the electronic atomizer reaches the second parameter, and the power module is controlled to stop energy output. At this time, it is determined that the electronic atomizer is in or about to be in a dry burning state. In this way, the problem of misjudgment caused by temperature fluctuations when the output voltage / power of the electronic atomizer is low is avoided, thereby improving the accuracy of identifying dry burning and thereby improving the utilization rate of the atomized medium.

[0062] In one embodiment, see Figure 5 The control module 120 includes a processing unit 121 and a switch unit 122. The processing unit 121 is connected to the enable end of the switch unit 122, and the power module 110 is connected to the heating element 130 through the switch unit 122; the processing unit 121 is used to control the conduction or closing of the switch unit 122 to control the energy provided by the power module 110 to the heating element 130.

[0063] Specifically, in this embodiment, the processing unit 121 can control the on or off of the switch unit 122 through the pulse signal, thereby controlling the energy provided by the power supply module 110 to the heating element 130. Figure 3 and Figure 4 As shown, this can be achieved by increasing the time for which the switch unit 122 is closed during the process of reducing the energy supplied to the heating element 130 .

[0064] In one embodiment, see Figure 6The detection module includes a temperature detection unit 141, which includes a sensor 1412 and a data acquisition subunit 1411 connected in series. The data acquisition subunit 1411 is also connected to the control module 120; the data acquisition subunit 1411 is used to obtain the temperature of the heating element 130 based on the data collected by the sensor 1412.

[0065] In this embodiment, the detection module 140 includes a temperature detection unit 141, which includes a sensor 1412 and a data acquisition subunit 1411 connected in series. The data acquisition subunit 1411 is also connected to the control module 120. The sensor 1412 is disposed on or near the heating element 130, or the sensor 1412 is connected to the heating element 130. The sensor 1412 is used to obtain operating parameters of the heating element 130. The sensor 1412 includes at least one of a resistance sensor, a thermoelectric potential sensor, a thermistor, or an infrared temperature sensor.

[0066] For example, if the sensor 1412 is a resistance sensor, the data acquisition subunit 1411 can obtain the resistance of the heating element 130 according to the resistance sensor, and use TCR (temperature coefficient of resistance) to calculate the temperature of the heating element 130, thereby realizing real-time detection of the temperature of the heating element 130.

[0067] It can be understood that, according to the description of the above embodiment, if the second parameter is output voltage / output power, the detection module 140 can be connected to the power module 110 and the processing module 120 respectively.

[0068] Based on the same inventive concept, the embodiments of the present application also provide a method for controlling an electronic atomizer for implementing the electronic atomizer involved above. The implementation solution provided by this method is similar to the implementation solution described in the above-mentioned electronic atomizer. Therefore, the specific limitations in the embodiments of the control method for one or more electronic atomizers provided below can be referred to the limitations on the electronic atomizer above and will not be repeated here.

[0069] In one embodiment, Figure 7 As shown, based on the above embodiment, the method includes:

[0070] Step 210, obtaining the operating parameters of the electronic atomizer;

[0071] Step 220: When the operating parameter reaches a first parameter, reduce the energy provided by the power module to the heating element, and control the operating parameter to be maintained at the first parameter;

[0072] Step 230: When the operating parameter reaches a second parameter, control the power module to stop energy output.

[0073] Specifically, this embodiment can be used in any of the above embodiments of the electronic atomizer, or an electronic atomizer including the above module, without limitation. In this embodiment, two parameters are set, namely the first parameter and the second parameter. The states of the electronic atomizer in this application include: normal oil supply state, oil shortage state, and dry burning state.

[0074] In one embodiment, the first parameter includes a first temperature, and the second parameter includes a second temperature, and the second temperature is greater than the first temperature. It should be noted that the first temperature is higher than the optimal atomization temperature of the atomizing medium in the electronic atomizer. For ease of understanding, taking the atomizing medium as glycerol (VG) as an example, the optimal atomization temperature of glycerol is 210±20 degrees Celsius, then the first temperature is 230±20 degrees Celsius, which is equivalent to the first temperature being 20 degrees Celsius higher than the optimal atomization temperature of the atomizing medium, which is equivalent to the first temperature being slightly higher than the optimal atomization temperature of the atomizing medium. It is understandable that the difference in atomizing medium will cause its optimal atomization temperature to change accordingly, and the first temperature will also change accordingly.

[0075] During normal use, see Figure 2 At time t1, the electronic atomizer is started, that is, at time t1, the power module 110 outputs corresponding energy to the heating element 130. The heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. At time t2, the user stops inhaling, and the temperature of the heating element 130 can drop or be maintained at a fixed temperature (this temperature is lower than the optimal atomization temperature of the atomizing medium, for example, maintained at a temperature of the preheated atomizing medium). The detection module 140 obtains the temperature of the heating element 130 in real time. If the temperature of the heating element 130 is between the optimal atomization temperature and the first temperature, it is determined that the electronic atomizer is in a normal oil supply state at this time.

[0076] See Figure 3, time t1 is the start-up, that is, the electronic atomizer starts at time t1, the power module 110 outputs corresponding energy to the heating element 130, the heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. If at time t3, the control module 120 obtains the detection module 140 to detect in real time that the temperature of the heating element 130 reaches the first temperature. At this time, it means that there is less atomizing medium in the electronic atomizer, that is, the electronic atomizer is in an oil-deficient state. In order to avoid the temperature of the heating element 130 from continuing to rise, and for normal use by the user (the temperature of the heating element 130 is slightly higher than the optimal atomizing temperature of the atomizing medium, which basically does not affect the atomization effect or the impact is small). From time t3, the control module 120 controls the power module 110 to reduce the corresponding energy output to the heating element 130 (the curve of reducing the output energy is as shown in FIG. Figure 3 From time t3 to time t4 (shown in FIG. 1 ), the heating element 130 is maintained at the first temperature.

[0077] See Figure 4 , time t1 is the start-up, that is, the electronic atomizer starts at time t1, the power module 110 outputs corresponding energy to the heating element 130, the heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. If at time t5, the control module 120 obtains the detection module 140 to detect in real time that the temperature of the heating element 130 reaches the first temperature. At this time, it means that there is less atomizing medium in the electronic atomizer, that is, the electronic atomizer is in an oil-deficient state. In order to avoid the temperature of the heating element 130 from continuing to rise, and for normal use by the user (the temperature of the heating element 130 is slightly higher than the optimal atomizing temperature of the atomizing medium, which basically does not affect the atomization effect or the impact is small). From time t5, the control module 120 controls the power module 110 to reduce the corresponding energy output to the heating element 130 (the curve of reducing the output energy is as shown in FIG. Figure 4 If the energy output to the heating element 130 is reduced, but the temperature of the heating element 130 still rises (the atomizing medium substantially does not enter or cannot enter the atomizing chamber of the electronic atomizer), it is determined that the electronic atomizer is in or is about to enter a dry-burn state, and the power module 110 is controlled to stop energy output, thereby preventing the electronic atomizer from dry-burning.

[0078] In another embodiment, the first parameter includes a first temperature, and the second parameter includes an output voltage / output power; during normal use, refer to Figure 4, t1 moment is start, that is, the electronic atomizer starts at t1 moment, the power module 110 outputs corresponding energy to the heating element 130, and the heating element 130 works under the energy provided by the power module 100, and its temperature gradually rises. If at t5 moment, the control module 120 obtains the temperature of the heating element 130 detected by the detection module 140 in real time reaches the first temperature. At this time, it is indicated that the atomization medium in the electronic atomizer is less, that is, the electronic atomizer is in the oil shortage state. In order to avoid the temperature of the heating element 130 continuing to rise, and the normal use of the user (the temperature of the heating element 130 is slightly higher than the optimal atomization temperature of the atomization medium, which basically does not affect the atomization effect or has little effect). From t5 moment, the control module 120 controls the power module 110 to output corresponding energy to the heating element 130 (the curve of reducing the output energy is shown from t5 moment to t6 moment Figure 4 The control module 120 can obtain the output voltage / output power of the power module 110. In the process of continuously reducing the output corresponding energy to the heating element 130, the temperature of the heating element 130 is still rising, and the control module 120 can also determine whether the output voltage / output power of the power module 110 is reduced to the lower limit of the corresponding working threshold. If the output voltage / output power of the power module 110 is reduced to the lower limit of the corresponding working threshold, and the temperature of the heating element 130 is still rising, it is determined that the electronic atomizer is in or about to be in the dry burning state, and the power module 110 is controlled to stop energy output, thereby avoiding the dry burning of the electronic atomizer.

[0079] The lower limit of the working threshold includes the lower limit of the output voltage / output power. For example, the lower limit of the output voltage / output power is any value in 10% to 40% of the maximum output voltage / maximum output power, that is, the lower limit of the output voltage is any value in 10% to 40% of the maximum output voltage; the lower limit of the output power is any value in 10% to 40% of the maximum output power.

[0080] The control method of the above-mentioned electronic atomizer includes: obtaining the operating parameters of the electronic atomizer; when the operating parameters reach a first parameter, reducing the energy provided by the power module to the heating element, controlling the operating parameters to maintain at the first parameter; when the operating parameters reach a second parameter, controlling the power module to stop energy output. Through the above method, the present application sets two parameters, namely the first parameter and the second parameter. When the operating parameters of the electronic atomizer reach the first parameter, the energy provided by the power module to the heating element is reduced to control the heating element to maintain at the first parameter; if the energy provided by the power module to the heating element is reduced, the operating parameters of the electronic atomizer reach the second parameter, and then the power module is controlled to stop energy output, at which time it is determined that the electronic atomizer is in or about to dry burn state. In this way, the problem of misjudgment caused by temperature fluctuations when the output voltage / power of the electronic atomizer is low is avoided, thereby improving the accuracy of identifying dry burning, thereby improving the utilization rate of the atomizing medium.
