Description

RELATED APPLICATIONS

This application is a continuation application of International application No. PCT/CN2024/090018, filed on Apr. 26, 2024, which claims priority to Chinese Patent Application No. 2023106199709, filed on May 29, 2023. The entire disclosure of the prior applications are hereby incorporated by reference.

TECHNICAL FIELD

This application relates to the field of atomization technologies, including to an electronic atomization device, and a control method and apparatus thereof.

BACKGROUND

In a conventional technology, an electronic atomization device may include a heating element, and the heating element may be a ceramic heating element. Using a ceramic heating element as an example, the ceramic heating element mainly includes a porous ceramic substrate, a heating film layer, and a pin conductive layer. Types of heating film layers may be classified into dense heating films and porous heating films. Due to significant differences in microstructures of the two types of heating films, puffing experience differs during atomization. Generally, the porous heating films have advantages in flavor indicators such as humidity and sweetness.

However, when atomization is performed by using a heating element including a porous heating film, the thickness of an oil film on the surface of the heating element may increase due to a capillary action in the heating element. During the heating process, a large number of bubbles may be generated around the heating element, leading to repeated formation and collapse of bubbles during use. This process of repeated formation and collapse of the bubbles may be accompanied by noise. Currently, an electronic atomization device using a porous heating film has the problem of excessive noise from a heating element.

DETAILED DESCRIPTION

The technical solutions in aspects of this disclosure are clearly and completely described in the following with reference to the accompanying drawings in the aspects of this disclosure. Apparently, the described aspects are merely some rather than all of the aspects of this disclosure. All other aspects obtained by a person of ordinary skill in the art based on the aspects in this disclosure without creative efforts shall fall within the protection scope of this disclosure.

By using the same porous ceramic substrate and heating film shape to prepare ceramic heating elements with porous heating films and dense heating films, when noise testing is conducted using the same power and atomization substrate, splattering noise of the porous heating film ceramic is significantly greater than that of the dense heating film. As shown in FIG. 1, ambient noise is generally 42 dB. When noise testing is conducted using the same power and atomization substrate, noise of an electronic atomization device including a dense heating film is 43.8 dB, and noise of the electronic atomization device including a porous heating film is 46.7 dB.

The following aspects are provided to reduce noise of the electronic atomization device including the porous heating film.

In an aspect, an electronic atomization device is provided. As shown in FIG. 2, the electronic atomization device includes a heating element 130, and an atomization surface of the heating element is provided with a porous heating film.

To better understand this disclosure, referring to FIG. 3 together, by using the heating element 130 shown in FIG. 3 as an example, the heating element 130 may include a ceramic substrate 131 and a porous heating film 132. The substrate 131 includes at least one through hole 1311. The thickness of the ceramic substrate may range from 0.5 mm to 5 mm, the pore size may range from 5 μm to 100 μm, and the porosity may range from 20 to 80%. The ceramic substrate 131 may include an atomization surface and a liquid absorbing surface adjacent to each other. The porous heating film 132 may be arranged on the atomization surface of the heating element 130. One end of the through hole 1311 is in communication with the liquid absorbing surface, and one end is in communication with the atomization surface. The material of the porous heating film 132 may be a heating material such as a nickel-chromium alloy, a stainless steel alloy, or an aluminum alloy. The structure of the porous heating film 132 may be in any shape such as an S shape or a W shape (there is a regional temperature gradient difference). The thickness of the porous heating film 132 may range from 5 μm to 100 μm. The porous heating film 132 also has a plurality of through holes, whose pore sizes may range from 5 μm to 40 μm and porosity may range from 30% to 60%. The through holes in the porous heating film 132 may be arranged in a disordered manner. In an aspect, paste of the porous heating film 132 is printed on a ceramic substrate green body and then co-sintered.

The power supply module 110 is configured to supply energy to the heating element 130.

In an aspect, the power supply module is further configured to supply energy to the processing module 120.

In an aspect, the power supply module 110 may be connected to the processing module 120 and the heating element 130 respectively. In this case, the processing module 120 may send a control instruction to the power supply module 110, to control output power and a battery frequency of the power supply module 110. In another aspect, the power supply module 110, the processing module 120, and the heating element 130 may be sequentially connected. In this case, the processing module 120 may implement its own on/off, so as to control on/off between the processing module 120 and the heating element 130, thereby controlling the battery frequency of the power supply module 120. The battery frequency refers to a pulse frequency, indicating a quantity of times of effective discharge per unit time (e.g., 1 s) within a discharge interval of a current outputted by the power supply module 110. In the foregoing manner, the power supply module 110 enables the processing module 120 and the heating element 130 to operate normally.

Further, when the power supply module 110 supplies energy, an output voltage generally ranges from 2 V to 10 V. The through hole 1311 is configured to be in communication with a storage tank for storing an atomization substrate and an inhalation mouthpiece, so that the atomization substrate in the storage tank can enter the heating element 130. The heating element 130 may atomize, during the operation, the atomization substrate in contact with the heating element 130, and a user may inhale the atomized atomization substrate by using the inhalation mouthpiece. In this aspect, the heating element 130 may include a plurality of through holes 1311 (generally referred to as a porous heating element). Generally, when a porous heating element is used, the user experience advantages in flavor such as humidity and sweetness during the inhalation. A capillary action may occur when the porous heating element is used. Specifically, referring to FIG. 4 together, FIG. 4 shows a state in which a capillary action occurs in one through hole 1311. That is, within a time during which the heating element 130 is not in operation, due to the presence of oil-containing unsaturated components, under the capillary action, an e-liquid in an e-liquid tank may be drawn into the through hole 1311 of the heating element 130 and even overflow, thereby increasing the thickness of an oil film of the heating element 130. The increase in the thickness of the oil film may lead to a higher bubble bursting frequency and louder splattering noise during splattering. The lower surface in FIG. 4 is the liquid absorbing surface of the ceramic substrate 131, and the upper surface is the atomization surface of the ceramic substrate 131.

The processing module 120 is configured to control the power supply module 110 to alternately supply energy to the heating element 130 according to a first preset power and a second preset power after detecting that the electronic atomization device is being puffed, where the first preset power is greater than the second preset power, the second preset power is greater than or equal to a minimum atomization power of an atomization substrate in the electronic atomization device, and an average power of the power supply module is equal to a preset power when a puffing time during which the electronic atomization device is being puffed is greater than or equal to a preset time.

Specifically, in a process in which the user puffs on the electronic atomization device, the processing module 120 detects a puffing action by using an airflow sensor in the electronic atomization device. In an aspect, after detecting the puffing action, the airflow sensor sends, to the processing module 120, information that the electronic atomization device is being puffed, or the processing module 120 acquires, from the airflow sensor, a signal detected by the airflow sensor, and detects, according to the signal detected by the airflow sensor, whether the electronic atomization device is being puffed. In another aspect, the user may alternatively trigger a heating start signal/a puff start signal by using a physical/virtual key in the electronic atomization device, so that the processing module 120 detects that the electronic atomization device is being puffed.

After it is detected that the electronic atomization device is being puffed, the power supply module 110 is controlled to alternately supply energy to the heating element 130 according to the first preset power and the second preset power. Referring to FIG. 5, when atomization starts, power on is performed in a first preset power (high power) mode, to quickly deplete the oil film on the surface of the ceramic and the heating film, so that the thickness of the oil film is reduced and a bursting frequency of splattering bubbles are decreased, thereby reducing noise. Subsequently, power on is performed in a second preset power (low power) mode, to prevent problems such as insufficient liquid supply and dry burning due to a continuous rise in an atomization temperature. Then, the temperature is increased in the high power mode, so as to prevent the problem of an insufficient atomized atomization substrate caused by an excessively low atomization temperature, further reduce the thickness of the oil film, and reduce the bursting frequency and noise of the splattering bubbles. Subsequently, the temperature is decreased in the low power mode. During the atomization, power on is continuously cyclically performed between the high power mode and the low power mode. The first preset power is greater than the second preset power, the second preset power is greater than or equal to a minimum atomization power of an atomization substrate in the electronic atomization device, and an average power of the power supply module is equal to a preset power when a puffing time during which the electronic atomization device is being puffed is greater than or equal to a preset time.

For example, it is assumed that one puff is taken, an average puffing time is 5 seconds, a puffing time of a same person is relatively stable, and a puffing force is also basically equal, that is, an amount of the inhaled atomization substrate is equal. For ease of understanding, referring to FIG. 5, the solid line represents a manner of alternating between the high power and the low power, and the dashed line represents a constant power manner. When the puffing time is equal and exceeds 5 seconds, an average power in the manner of alternating between the high power and the low power is equal to a power used in the constant power manner, resulting in an equivalent total atomization amount. In this case, the constant power is the preset power. Referring to FIG. 6 and FIG. 7 together, upon comparison (other conditions are all the same) between a constant power manner (an output power of the power supply module 110 remains constant in each cycle) and a variable power manner (the output power of the power supply module 110 is not constant in each cycle, that is, the power supply module 110 has a plurality of output powers in each cycle), the thickness of the oil film in the through hole 1311 is significantly reduced in the variable power manner, and the thickness of the oil film in the through hole 1311 is lower by h in the variable power manner compared to the constant power manner. Meanwhile, when other conditions are the same, comparisons between bubble burst frequencies at the constant power and the variable power show that only during an initial period of time (about 0.3 seconds), the bubble bursting frequency in the variable power manner is higher than that in the constant power manner. After normal operation (around 0.4 seconds later), the bubble bursting frequency in the variable power manner is lower than that in the constant power manner. In this way, the bubble bursting frequency is decreased, and the noise is correspondingly reduced.

It should be noted that, if an actual puffing time is lower than a normal puffing time (the normal puffing time is generally obtained by averaging historical puffing times of the user, or is set by a technician according to experience, for example, 3 seconds), the average power in the manner of alternating between the high power and the low power is higher than the preset power.

The foregoing electronic atomization device includes: a heating element, an atomization surface of the heating element being provided with a porous heating film; a power supply module, configured to supply energy to the heating element; and a processing module, configured to control the power supply module to alternately supply energy to the heating element according to a first preset power and a second preset power after detecting that the electronic atomization device is being puffed, where the first preset power is greater than the second preset power, the second preset power is greater than or equal to a minimum atomization power of an atomization substrate in the electronic atomization device, and an average power of the power supply module is equal to a preset power when a puffing time during which the electronic atomization device is being puffed is greater than or equal to a preset time. In the foregoing manner, in this disclosure, after it is detected that the electronic atomization device is being buffed, energy is supplied to the heating element by using a first power (a higher power). In this way, the temperature is increased first by using the higher power as described, the thickness of the oil film produced by the capillary action in the through hole of the heating element is reduced, the bursting frequency of the splattering bubbles is decreased, and the noise is reduced. Then, the temperature is reduced by using a second power (a lower power). During the atomization, power on continuously cyclically alternates between the high power mode and the low power mode, which reduces negative experience of splattering noise while ensuring the flavor.

In an aspect, the processing module 120 is further configured to:

• • sort a plurality of first preset sub-powers in a first preset power in descending order within a first preset time, to obtain a sorting result;
  • control the power supply module 110 to supply energy to the heating element 130 according to the sorting result; and
  • control the power supply module 110 to supply energy to the heating element 130 according to the second preset power within a second preset time.

Specifically, referring to FIG. 8, the first preset power may include a plurality of first preset sub-powers, and during the heating, the plurality of first preset sub-powers in the first preset power may be sorted in descending order, to obtain the sorting result. After puffing is detected, the power supply module 110 is controlled to supply energy to the heating element 130 according to the sorting result of the sub-powers. That is, energy is first supplied to the heating element 130 at a maximum power, and then the power is sequentially reduced (for example, energy is supplied to the heating element 130 at a maximum power of 7.4 W, and then energy is supplied to the heating element 130 at 7.3 W). After the energy is supplied by using the sorting result of all the sub-powers of the first preset power (e.g., after 0.6 seconds), the power supply module 110 is controlled to supply energy to the heating element 130 according to the second preset power (e.g., 5.6 W) for a second time (e.g., for 0.2 seconds). After the second time, the power supply module 110 is controlled to supply energy to the heating element 130 for a third time (e.g., for 0.3 second) by using a third preset power (an intermediate value between the first preset power and the second preset power, and between the maximum value and the minimum value, for example, 7.2 W). After the third time, the power supply module 110 is controlled to supply energy to the heating element 130 for a fourth time (e.g., for 0.2 second) by using the second preset power (e.g., 5.6 W). Subsequently, power supply is periodically controlled alternately by using a high power value and a low power value that are between the second power and the third power.

In an aspect, the processing module 120 is further configured to: control, during a single puff on the electronic atomization device, the power supply module 110 to supply energy to the heating element 130 at sequentially decreased first preset sub-powers each time.

Specifically, in a process of alternately supplying energy to the heating element 130 by using a high power and a low power, each time the high power is used, only one first preset sub-power may be selected, and the selected first preset sub-power is sequentially decreased each time. A minimum first preset sub-power and the second preset power are periodically used for power supply. That is, each time the power supply module 110 supplies energy to the heating element 130, power is supplied using the high power (the high power is selected from the first preset sub-powers), and the used first preset sub-power is sequentially decreased (or in other words, the first preset sub-power used each time is no higher than the first preset sub-power used last time). Referring to FIG. 9, it is assumed that each puffing time is 5 seconds, the first preset sub-power used for the first time is 7.4 W, the first preset sub-power used for the second time is 7.2 W, the first preset sub-power used at about 1 second is 7.1 W, the first preset sub-power used at about 1.5 seconds is 7.1 W, the first preset sub-power used at about 2.5 seconds is 6.8 W, and so on. In this way, the average power of the power supply module is equal to the preset power. A difference between this aspect and the previous aspect lies in that, each time the high power is selected to supply energy, only one first preset sub-power is used, while in the previous implementation, each time the high power is selected for energy supply, a plurality of first preset sub-powers may be used.

In an aspect, within a time during which the power supply module 110 is controlled to supply energy to the heating element 130 according to the first preset power or the second preset power, energy is supplied to the heating element by using at least one battery frequency. In this case, the battery frequency is higher than a preset frequency. Referring to FIG. 10, according to experiments, in three manners: a constant power, a variable power+a low frequency (100 Hz), and a variable power +a high frequency (300 Hz), noise is sequentially reduced. The low frequency refers to a frequency lower than 250 Hz, the high frequency refers to a frequency at least higher than 250 Hz, and the variable power refers to a manner of alternately supplying power by using the first preset power and the second preset power. In this figure, the same variable power control manner is employed, and only battery frequencies of the power supply module 110 are different. Exemplarily, as shown in FIG. 11, FIG. 11 shows comparisons between bubble bursting frequencies in different control manners during atomization. Based on experimental data, comparisons between bubble bursting frequencies in a variable power+different battery frequencies manner and a constant power manner within different atomization times show that the bubble bursting frequency in the variable power manner is significantly more decreased than that in the constant power manner. On the basis of the same variable power, a higher battery frequency indicates a lower bubble bursting frequency.

In an aspect, the processing module 120 is further configured to: control, within a time during which energy to is supplied to the heating element 130 according to the first preset power or the second preset power, the power supply module 110 to supply energy to the heating element by using at least two different battery frequencies.

The battery frequency of the power supply module 110 is controlled within the time during which the power supply module 110 is controlled to supply energy to the heating element 130 according to the first preset power or the second preset power. For ease of description, the time during which the power supply module 110 is controlled to supply energy to the heating element 130 according to the first preset power is defined as a first time, and the time during which the power supply module 110 is controlled to supply energy to the heating element 130 according to the second preset power is defined as a second time. That is, energy is supplied to the heating element by using at least two different battery frequencies in the first time, and energy is supplied to the heating element by using at least two different battery frequencies in the second time.

The energy supplied by the power supply module 110 to the heating element 130 remains unchanged in each time for supplying energy. That is, in this aspect, only the battery frequency is changed, and the supply power is not changed. Each time includes at least two different battery frequencies. Exemplarily, assuming that a time of one puff is 5 seconds, a power supply frequency of a battery is set according to a preset frequency curve during one puff (5 seconds). The power supply frequency of the battery within each first time or second time includes two or more frequency segments, and the power supply frequency of the battery alternates periodically. In each cycle, a duration of each battery frequency segment ranges from 0.1 seconds to 1.5 seconds. According to the foregoing description, it may be understood that, in the technical solution of this disclosure, compared with the use of a constant battery frequency manner in the corresponding technology, the battery frequency in this disclosure is variable, and a plurality of frequencies are used in each first time or second time. On the basis of the equal energy provided by the power supply module 110 to the heating element 130 in each unit cycle, compared with the use of the constant battery frequency manner, a quantity of changes in a direction of a current in a unit cycle in this disclosure is increased. In this way, if the battery frequency increases in each first time or second time, each power-off time is shorter within each first time or second time (if the energy is equal within each first time or second time, a total power-off time within each first time or second time remains unchanged), that is, the power-off time is fragmented. If each power-off time is shorter, a time during which a capillary action occurs is shortened, resulting in a decrease in the thickness of the oil film in the through hole. After the thickness of the oil film is decreased, during the heating of the heating element 130, a quantity of bubbles generated is reduced, and a bubble bursting frequency is also lowered.

In an aspect, the processing module 120 is further configured to: select battery frequencies from different control frequencies in an order of first increasing and then decreasing to control the power supply module 110 to supply energy to the heating element 130 within the time during which the power supply module is controlled to supply energy to the heating element according to the first preset power or the second preset power. Exemplarily, as shown in FIG. 12, the first time is divided into 5 parts. In this aspect, in the first time of the first part, the power supply module 110 is controlled to supply energy to the heating element 130 according to a first preset battery frequency (e.g., 350 Hz), the power supply module 110 is controlled to supply energy to the heating element 130 according to a second preset battery frequency (e.g., 490 Hz), and then the power supply module 110 is controlled to supply energy to the heating element 130 according to a third preset battery frequency (e.g., 650 Hz). Then, in the first time of the second part, the power supply module 110 is controlled to supply energy to the heating element 130 according to the third preset battery frequency (e.g., 650 Hz), the power supply module 110 is controlled to supply energy to the heating element 130 according to the second preset battery frequency (e.g., 490 Hz), and then the power supply module 110 is controlled to supply energy to the heating element 130 according to the first preset battery frequency (e.g., 350 Hz). Finally, the above operations in the time of the first part and the second part are repeated in the 3^rd part to the 5^th part, and so on.

In another aspect, the processing module 120 is further configured to:

• • control, based on battery frequencies selected from different control frequencies in ascending order, the power supply module to supply energy to the heating element within the time during which the power supply module is controlled to supply energy to the heating element according to the first preset power or the second preset power.

Exemplarily, referring to FIG. 13, the processing module 120 controls, based on battery frequencies selected from different control frequencies in ascending order, the power supply module 110 to supply energy to the heating element 130. An execution sequence of the battery frequencies within each time may be different, and certainly, the execution sequence of the battery frequencies in each unit cycle may be the same.

Exemplarily, when it is detected that the electronic atomization device is being puffed, the power supply module 110 is controlled to provide the heating element 130 with a first battery frequency for a first preset time; after the first preset time, provide the heating element 130 with a second battery frequency for a second preset time, where the second battery frequency is higher than the first battery frequency; after the second preset time, provide the heating element with a third battery frequency for a third preset time, where the third battery frequency is higher than the second battery frequency; and after the third preset time, provide the heating element with a fourth battery frequency for a fourth preset time, where the fourth battery frequency is lower than the third battery frequency. The first preset time to the fourth preset time constitute a unit cycle. This may be repeated in each subsequent cycle.

In yet another aspect, the processing module 120 is further configured to: randomly select a battery frequency from different battery frequencies to control the power supply module 110 to supply energy to the heating element 130. Exemplarily, when it is detected that the electronic atomization device is being puffed, the power supply module 110 is controlled to provide the heating element 130 with the first battery frequency for the first preset time; after the first preset time, provide the heating element 130 with the third battery frequency for the second preset time; after the second preset time, provide the heating element with the second battery frequency for the third preset time; and after the third preset time, provide the heating element with the fourth battery frequency for the fourth preset time. The first preset time to the fourth preset time constitute a unit cycle. The first battery frequency, the second battery frequency, the third battery frequency, and the fourth battery frequency sequentially increase. In a second unit cycle, one frequency is randomly selected from the first battery frequency to the fourth battery frequency within each preset time (the first preset time to the fourth preset time).

In an aspect, the battery frequencies are all less than a preset threshold. Specifically, to ensure the flavor for the user during the puffing, in an actual process, a splattering (generated bubbles burst, i.e., a splattering phenomenon) process is required. A certain degree of splattering enables mixing the atomized atomization substrate with the un-atomized atomization substrate, allowing the user to inhale, during the puffing, an atomization substrate which is a mixture of the un-atomized atomization substrate and the atomized atomization substrate, thereby ensuring the flavor for the user during the puffing. In this aspect, the battery frequencies are all less than the preset threshold, to prevent an excessively short time for producing capillary liquid absorption in the through hole in the heating element 130.

As can be seen according to the foregoing description, noise generated in the constant power manner is higher than that generated in the constant power+variable frequency manner. Based on the use of a variable power, a higher battery frequency indicates lower noise. Based on the use of the variable power, noise generated in the constant frequency manner is also higher than that generated in the variable frequency manner. As shown in FIG. 14, noise generated in the variable power+variable frequency manner can be close to the ambient noise, and the user is basically unaware of the noise.

Based on a same inventive concept, an aspect of this disclosure further provides a control method for an electronic atomization device for implementing the foregoing electronic atomization device. An implementation solution provided by the method for resolving the problem is similar to the implementation solution described in the foregoing electronic atomization device. Therefore, for specific limitations on one or more aspects of the control method for an electronic atomization device provided below, refer to the foregoing limitations on the electronic atomization device. Details are not described herein again.

In an aspect, as shown in FIG. 15, this disclosure provides a control method for an electronic atomization device. The electronic atomization device includes a heating element with a porous heating film provided on an atomization surface and a power supply module. The method includes the following steps:

• • Step S1510: Detect whether the electronic atomization device is being puffed.
  • Step S1520: Control the power supply module to alternately supply energy to the heating element according to a first preset power and a second preset power after it is detected that the electronic atomization device is being puffed, where the first preset power is greater than the second preset power, the second preset power is greater than or equal to a minimum atomization power of an atomization substrate in the electronic atomization device, and an average power of the power supply module is equal to a preset power when a puffing time during which the electronic atomization device is being puffed is greater than or equal to a preset time.

For an execution process of each step in this aspect, refer to the foregoing aspect. Details are not described herein again.

In the foregoing control method for an electronic atomization device, after it is detected that the electronic atomization device is being buffed, energy is supplied to the heating element by using a high power (a first power). In this way, the temperature is increased first by using the higher power as described, the thickness of the oil film produced by the capillary action in the through hole of the heating element is reduced, the bursting frequency of the splattering bubbles is decreased, and the noise is reduced. Then, the temperature is reduced by using a second power (a lower power). During the atomization, power on continuously cyclically alternates between the high power mode and the low power mode, which reduces negative experience of splattering noise while ensuring the flavor.

In an aspect, the controlling the power supply module to alternately supply energy to the heating element according to a first preset power and a second preset power includes:

• • sorting a plurality of first preset sub-powers in a first preset power in descending order within a first preset time, to obtain a sorting result;

In an aspect, the controlling, within a time during which energy is supplied to the heating element according to the first preset power or the second preset power, the power supply module to supply energy to the heating element by using at least two different battery frequencies includes:

• • controlling, based on battery frequencies selected from different control frequencies in ascending order, the power supply module to supply energy to the heating element within the time during which the power supply module is controlled to supply energy to the heating element according to the first preset power or the second preset power.

In an aspect, the controlling, within a time during which energy is supplied to the heating element according to the first preset power or the second preset power, the power supply module to supply energy to the heating element by using at least two different battery frequencies includes:

• • controlling, based on battery frequencies selected from different control frequencies in descending order, the power supply module to supply energy to the heating element within the time during which the power supply module is controlled to supply energy to the heating element according to the first preset power or the second preset power.

In an aspect, the battery frequencies are all less than a preset threshold.

It should be understood that, although the steps are displayed sequentially as indicated by the arrows in the flowcharts of the aspects, these steps are not necessarily performed sequentially according to the sequence indicated by the arrows. Unless otherwise explicitly specified in this disclosure, execution of the steps is not strictly limited, and the steps may be performed in other sequences. Moreover, at least some of the steps in each aspect as described above may include a plurality of steps or a plurality of stages. The steps or stages are not necessarily performed at the same moment but may be performed at different moments. Execution of the steps or stages is not necessarily sequentially performed, but may be performed in turn or alternately with other steps or at least some of steps or stages of other steps.
