Description

CROSS-REFERENCE TO PRIOR APPLICATION

This application is a continuation of International Patent Application No. PCT/CN 2024/101808, filed on Jun. 27, 2024, which claims priority to Chinese Patent Application No. 202310898251.5, filed on Jul. 20, 2023. The entire disclosure of both applications is hereby incorporated by reference herein.

FIELD

This application relates to the field of atomization devices, and in particular, to an electronic atomization device, and a control method and apparatus therefor.

BACKGROUND

A conventional technology discloses an electronic atomization device, which is generally composed of components such as a heating element, a battery, and a control circuit. Currently, many electronic atomization devices typically employ constant power to atomize an atomization substrate.

However, the atomization substrate is usually composed of a propylene glycol (PG) polymer and a vegetable glycerin (VG) polymer. The propylene glycol polymer has a low boiling point (the boiling point of the propylene glycol polymer is around 188° C.), while the vegetable glycerin polymer has a high boiling point (the boiling point of the vegetable glycerin polymer is around 290° C.).

Currently, to rapidly obtain a sufficient atomization amount for user inhalation, many electronic atomization devices employ a control method that involves quick temperature rise followed by cooling, enabling the heating element to rapidly heat up and generate an adequate amount of atomized atomization substrate. However, due to different boiling points of materials within the atomization substrate and a large quantity of the atomization substrate, if high power (greater than or equal to the highest boiling point of the materials within the atomization substrate) is used for atomizing the atomization substrate, low-boiling-point portions of the atomization substrate reach the boiling point too quickly, while high-boiling-point portions do not reach the boiling point, leading to liquid spit-back. After liquid spit-back occurs, the high-boiling-point portions of the atomization substrate mix into the atomized atomization substrate in a liquid form, thereby affecting the user inhalation experience.

SUMMARY

In an embodiment, the present invention provides an electronic atomization device, comprising: a processing module; a power module; and a heating element, wherein the power module is configured to supply energy to the heating element and the processing module, respectively, wherein the processing module is configured to control the power module to supply energy to the heating element at a first preset power within a first time period and at a second preset power within a second time period during inhalation of the electronic atomization device, wherein the first preset power is less than a minimum atomization power corresponding to a first portion of an atomization substrate in the electronic atomization device, wherein the second preset power is greater than or equal to the minimum atomization power corresponding to the first portion of the atomization substrate in the electronic atomization device, and wherein a sum of the first time period and the second time period is less than or equal to a total duration of a single inhalation session of the electronic atomization device.

Details of one or more embodiments of this application are provided in the accompanying drawings and descriptions below. Other features, objectives, and advantages of this application become apparent from the specification, the accompanying drawings, and the claims.

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

In an embodiment, an electronic atomization device is provided. As shown in FIG. 1, the electronic atomization device includes:

• • a processing module 120, a power module 110, and a heating element 130.

The power module 110 is configured to supply energy to the heating element 130 and the processing module 120 respectively, such that the processing module 120 and the heating element 130 can operate normally.

In an embodiment, the power 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 module 110, to control 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 may be connected in series. In this case, the processing module 120 may control the connection and disconnection between the processing module 120 and the heating element 130 by switching its own on/off state, thereby controlling the output power of the power module 110 to the heating element 130.

The processing module 120 is configured to control the power module to supply energy to the heating element at a first preset power within a first time period and at a second preset power within a second time period during inhalation of the electronic atomization device. The first preset power is less than the minimum atomization power corresponding to a first portion of the atomization substrate in the electronic atomization device, and the second preset power is greater than or equal to the minimum atomization power corresponding to the first portion of the atomization substrate in the electronic atomization device. The sum of the first time period and the second time period is less than or equal to a total duration of a single inhalation session of the electronic atomization device.

Specifically, the electronic atomization device in this embodiment stores the atomization substrate. During specific implementation, the atomization substrate may be stored in a cartridge (storage chamber). The atomization substrate includes at least a first portion and a second portion, with the boiling point of the first portion being higher than that of the second portion. Exemplarily, the first portion may be a vegetable glycerin (VG) polymer, and the second portion may be a propylene glycol (PG) polymer. During specific implementation, the composition of the atomization substrate may be selected according to actual conditions, which is not limited herein.

To better understand this application, reference is also made to FIG. 2. Taking the heating element 130 depicted in FIG. 2 as an example, each heating element 130 includes a ceramic substrate 131 and a porous heating film 132. The substrate 131 includes at least one through hole 1311. The ceramic substrate 131 includes an atomization surface and a liquid-absorption surface which are opposite to each other. The porous heating film 132 is arranged on the atomization surface of the heating element 130. One end of the through hole 1311 communicates with the liquid-absorption surface, and the other end communicates with the atomization surface. The material of the porous heating film 132 may be a heat-generating material such as nichrome alloy, stainless steel alloy, or aluminum alloy. The structure of the porous heating film 132 may be in any shape, such as S-shaped or W-shaped (with regional temperature gradient differences). In an embodiment, the slurry of the porous heating film 132 is printed onto a ceramic substrate body and then co-sintered them together. The through hole 1311 is used to communicate the storage chamber storing the atomization substrate with a mouthpiece, thereby allowing the atomization substrate in the storage chamber to enter the heating element 130. During operation, the heating element 130 may atomize the atomization substrate that comes into contact with the heating element 130, and a user can inhale the atomized atomization substrate through the mouthpiece. Specifically, reference is also made to FIG. 3, FIG. 3 illustrates a state in which a capillary action generated in one through hole 1311. That is, during a period when the heating element 130 is not in operation, due to the presence of liquid unsaturation, the capillary action draws e-liquid from an oil reservoir into the through hole 1311 of the heating element 130, and may even cause overflow, increasing the thickness of the e-liquid film on the heating element 130. In FIG. 3, a lower surface represents the liquid-absorption surface of the ceramic substrate 131, while an upper surface represents the atomization surface of the ceramic substrate 131. As another embodiment, the atomization substrate may also flow directly from the storage chamber to the atomization surface of the heating element 130. The heating element 130 shown in FIG. 2 is merely used as an example, and during specific implementation, the heating element may also have another structure.

Since the atomization substrate in the storage chamber is a mixture of the first portion and the second portion, after flowing onto the atomization surface of the heating element 130, the atomization substrate on the atomization surface of the heating element 130 also includes the second portion with a low boiling point and the first portion with a high boiling point. During a heating process of the heating element 130, if the heating element 130 heats up too rapidly, the second portion reaches the boiling point quickly and expands. Upon expanding to a certain extent, the second portion ruptures, thereby causing the first portion encapsulating the second portion to burst, resulting in a liquid spit-back phenomenon.

To solve the problem of liquid spit-back, after detecting that the electronic atomization device is in use for inhalation, the electronic atomization device enters an inhalation state. Specifically, the processing module 120 detects an inhalation action through an airflow sensor within the electronic atomization device. As an embodiment, after detecting the inhalation action, the airflow sensor sends the information indicating inhalation of the electronic atomization device to the processing module 120. Alternatively, the processing module 120 acquires a detected signal from the airflow sensor and detects, according to the signal detected by the airflow sensor, whether the electronic atomization device is in use for inhalation. As another embodiment, the user may also trigger a heating start signal/inhalation start signal through a physical/virtual button on the electronic atomization device, enabling the processing module 120 to detect that the electronic atomization device is in use for inhalation.

During inhalation of the electronic atomization device, the power module 110 is controlled to supply energy to the heating element 130 at a first preset power within a first time period and at a second preset power within a second time period. Referring to FIG. 4, within one cycle, the second time period follows the first time period. At the beginning of atomization, the processing module 120 controls the power module 110 to supply energy to the heating element 130 at the first preset power (P1) that is less than the minimum atomization power corresponding to the first portion. In this case, the output power of the power module 110 is low, and the temperature of the heating element 130 rises slowly. Accordingly, the second portion with the low boiling point may be allowed to atomize, while a small portion of the first portion with the high boiling point can also atomize (i.e., the amount of atomization of the second portion is greater than that of the first portion), thereby consuming an e-liquid film on surfaces of the ceramic substrate and the heating film, and reducing the thickness of the e-liquid film. On one hand, the second portion within the atomization substrate is reduced, and on the other hand, the reduced thickness of the e-liquid film can allow the second portion to rupture quickly after expansion or to be atomized directly, thereby avoiding the liquid spit-back phenomenon. After the first time period (T1), the processing module 120 controls the power module 110 to supply energy to the heating element 130 at the second preset power (P2) that is greater than or equal to the minimum atomization power corresponding to the first portion. In this case, the temperature of the heating element 130 continues to rise, enabling rapid atomization of the atomization substrate and increasing the atomization amount. The second preset power (P2) is maintained for the second time period (T2) until the end or near the end of the current inhalation session. That is, the sum of the first time period and the second time period is less than or equal to a total duration of a single inhalation session of the electronic atomization device. Exemplarily, assuming an average inhalation duration of 5 seconds for a single puff, the sum of the first time period and the second time period is less than or equal to 5 seconds. It should be noted that a relationship between the first time period and the second time period may be set according to actual conditions. For example, when a large atomization amount is required, the second time period may be set long. When a sweet taste is preferred (since sweetness mainly comes from the second portion of the atomization substrate), the first time period may be set long.

The above-mentioned electronic atomization device includes the processing module, the power module, and the heating element. The power module is configured to supply energy to the heating element and the processing module respectively. The processing module is configured to control the power module to supply energy to the heating element at the first preset power within the first time period and at the second preset power within the second time period during inhalation of the electronic atomization device. The atomization substrate in the electronic atomization device includes at least the first portion and the second portion, with the boiling point of the first portion being higher than that of the second portion. The first preset power is less than the minimum atomization power corresponding to the first portion, and the second preset power is greater than or equal to the minimum atomization power corresponding to the first portion. The sum of the first time period and the second time period is less than or equal to the total duration of a single inhalation session of the electronic atomization device. Through the above-mentioned method in this application, during inhalation of the electronic atomization device, at the beginning of inhalation, the amount of atomization substrate is relatively high. By heating the atomization substrate at the relatively low first preset power first, the amount of atomization substrate near the heating element is reduced after which the device continues to raise the temperature at the second preset power, thereby avoiding the liquid spit-back phenomenon caused by rapid temperature rise and boiling of the second portion with low boiling point within the atomization substrate, enhancing the taste for the user during the inhalation process.

As an embodiment, the processing module 120 is further configured to:

• • control the power module 110 to supply energy to the heating element 130 at the first preset power within the first time period, at the second preset power within the second time period, and at a third preset power within a third time period during inhalation of the electronic atomization device.

The third preset power is less than the second preset power, and the sum of the first time period, the second time period, and the third time period is equal to the total duration of a single inhalation session of the electronic atomization device.

Specifically, the difference between this embodiment and the previous embodiment lies in that in the previous embodiment, the time of a single inhalation session is divided into two time periods, whereas in this application, the time of a single inhalation session is divided into three time periods. Reference is also made to FIG. 5, within one cycle, the second time period follows the first time period, and the third time period follows the second time period. The processing module 120 controls the power module 110 to supply energy to the heating element 130 at the first preset power (P1) that is less than the minimum atomization power corresponding to the first portion. In this case, the output power of the power module 110 is low, and the temperature of the heating element 130 rises slowly. Accordingly, the second portion with the low boiling point may be allowed to atomize, while a small portion of the first portion with the high boiling point can also atomize (i.e., the amount of atomization of the second portion is greater than that of the first portion), thereby consuming the e-liquid film on the surfaces of the ceramic substrate and the heating film, and reducing the thickness of the e-liquid film. On one hand, the second portion within the atomization substrate is reduced, and on the other hand, the reduced thickness of the e-liquid film can allow the second portion to rupture quickly after expansion or to be atomized directly, thereby avoiding the liquid spit-back phenomenon. After the first time period (T1), the processing module 120 controls the power module 110 to supply energy to the heating element 130 at the second preset power (P2) that is greater than or equal to the minimum atomization power corresponding to the first portion. In this case, the temperature of the heating element 130 continues to rise, enabling rapid atomization of the atomization substrate and increasing the atomization amount. After continuing for the second time period, the processing module 120 controls the power module 110 to supply energy to the heating element 130 at the third preset power (P3) for the third time period. The third preset power is less than the second preset power, and the sum of the first time period, the second time period, and the third time period is equal to the total duration of a single inhalation session of the electronic atomization device. That is, the relatively high second preset power is used first, followed by the relatively low third preset power to supply energy. This is primarily because, within the third time period, the current inhalation is nearing its end, and in this case, the user inhalation strength decreases, requiring a less atomization amount. Therefore, the power can be reduced to decrease the energy supplied to the heating element 130. A relationship between the first preset power and the third preset power may be set according to actual conditions. For example, the first preset power is less than or equal to the third preset power; alternatively, the first preset power is greater than or equal to the third preset power.

Further, the third preset power is less than or equal to an average value of the first preset power and the second preset power. That is, within the first time period, the minimum first preset power is used for slow heating to reduce the atomization substrate near the heating element 130. Then, within the second time period, the highest second preset power is employed for rapid heating to increase the atomization amount. Finally, within the third time period, the third preset power is used to stabilize the atomization amount.

The first time period, the second time period, and the third time period may also be set according to actual conditions. For example, the first time period, the second time period, and the third time period may be equal; or both the first time period and the second time period are less than one third of the total duration, and the third time period is greater than one third of the total duration. The total duration refers to a total duration of a single inhalation session. In this case, correspondingly, during a single inhalation process, the first time period, the second time period, and the third time period are configured to have a combined duration that covers the total duration of the inhalation process.

As another embodiment, during a single inhalation process, the first time period, the second time period, and the third time period are configured to be periodically distributed, with a combined duration of a plurality of cycles covering the total duration of the inhalation process. Specifically, within one cycle, durations of the first time period, the second time period, and the third time period are equal; or within one cycle, both the first time period and the second time period are less than one third of the total duration, while the third time period is greater than one third of the total duration.

In some embodiments, the first preset power is greater than or equal to the minimum atomization power corresponding to the second portion and less than the minimum atomization power corresponding to the first portion, thereby atomizing the second portion as quickly as possible within the first time period, avoiding the liquid spit-back phenomenon. Of course, the first preset power may also be slightly less than the minimum atomization power corresponding to the second portion, which can basically avoid the liquid spit-back phenomenon.

It should be understood that the first preset power is greater than or equal to the minimum atomization power corresponding to the second portion and less than the minimum atomization power corresponding to the first portion, thereby ensuring that the overall atomization amount remains comparable to that in conventional technologies and meets the inhalation demands of the user. Exemplarily, assuming a constant output power of P=7.5 W and an inhalation time of T=3 S, to ensure the same energy supply, variable power parameters may be set as P1×T1+P2×T2+P3×T3=P×T. During a first segment of inhalation, there is a large amount of e-liquid on the surface of the heating element 130 and components connecting to the storage chamber, P1 is set to 6.5 W to prevent the “liquid spit-back” phenomenon caused by violent atomization of the atomization substrate due to an excessively high heating rate of the heating element 130, and avoid rapid atomization and overflow of the second portion with the low boiling point within the atomization substrate. During a second segment of inhalation, when the amount of e-liquid on the surface of the heating element 130 and the components connecting to the storage chamber is reduced and the temperature rises, P2 may be set to 8.5 W to heat the atomization substrate and fully atomize the first portion with high boiling point within the atomization substrate. During a third segment of inhalation, when the heating element 130 and the atomization substrate on the heating element 130 reach a set maximum atomization temperature and the amount of atomization substrate on the heating element 130 is further reduced, P3 may be set to less than or equal to 7.5 W to maintain a constant atomization temperature and increase the overall vapor amount. Upon completion of inhalation, the device enters the next cycle and repeats the execution of the above-mentioned process.

In some embodiments, the electronic atomization device further includes:

• • a detection module, configured to detect an inhalation signal of the electronic atomization device.

The processing module 120 is further configured to: determine the first time period and the second time period according to the inhalation signal, and control the power module to supply energy to the heating element at the first preset power within the first time period and at the second preset power within the second time period.

Specifically, the difference between this embodiment and the above-mentioned embodiments lies in that the first time period and the second time period in this embodiment are not fixed. In this embodiment, the detection module is also arranged in the electronic atomization device, and can detect the inhalation signal of the electronic atomization device. The processing module 120 can determine an inhalation strength according to the detected inhalation signal. The greater the inhalation strength, the larger the inhalation signal. Therefore, the processing module 120 can determine the first time period and the second time period. Exemplarily, if an inhalation value corresponding to the inhalation signal is less than or equal to a preset inhalation strength, the first time period is a preset time period, such as 1 second. If the inhalation value corresponding to the inhalation signal is greater than the preset inhalation strength within 1 second, the first time period is shortened to 0.8 seconds. It should be understood that if the inhalation duration in this case is greater than 0.8 seconds but less than 1 second, the device immediately transitions to the second time period. As another embodiment, the first time period and the second time period may also be correspondingly set according to the inhalation signal value, and are dynamically adjusted according to the inhalation signal. Then, the processing module 120 controls the power module to supply energy to the heating element at the first preset power within the first time period, and the processing module 120 supplies energy to the heating element at the second preset power within the second time period.

In some embodiments, the electronic atomization device further includes:

• • a processing module 120, a power module 110, and a heating element 130.

The power module 110 is configured to supply energy to the heating element 130 and the processing module 120 respectively.

The processing module 120 is configured to control the power module 110 to supply energy to the heating element 130 at a first preset power within a first time period, at a second preset power within a second time period, and at a third preset power within a third time period during inhalation of the electronic atomization device.

The third preset power is less than the second preset power, and the first preset power is less than the second preset power.

To solve the problem of liquid spit-back, after detecting that the electronic atomization device is in use for inhalation, the electronic atomization device enters the inhaled state. Specifically, the processing module 120 detects an inhalation action through an airflow sensor within the electronic atomization device. As an embodiment, after detecting the inhalation action, the airflow sensor sends the information indicating inhalation of the electronic atomization device to the processing module 120. Alternatively, the processing module 120 acquires a detected signal from the airflow sensor and detects, according to the signal detected by the airflow sensor, whether the electronic atomization device is in use for inhalation. As another embodiment, the user may also trigger a heating start signal/inhalation start signal through a physical/virtual button on the electronic atomization device, enabling the processing module 120 to detect that the electronic atomization device is in use for inhalation.

During inhalation of the electronic atomization device, the power module 110 is controlled to supply energy to the heating element 130 at the first preset power within the first time period and at the second preset power within the second time period. In other words, in this embodiment, the heating element 130 is controlled to heat at a low temperature first and then at a high temperature (the temperature corresponding to the second preset power). Finally, within the third time period near the end of inhalation, low-temperature heating is employed again. A specific control process is basically the same as that in the above-mentioned embodiment.

In an embodiment, the first preset power is less than or equal to the third preset power; or

the first preset power is greater than or equal to the third preset power.

In an embodiment, the third preset power is less than or equal to an average value of the first preset power and the second preset power.

In an embodiment, during a single inhalation process, the first time period, the second time period, and the third time period are configured to have a combined duration that covers the total duration of the inhalation process; or

• • during a single inhalation process, the first time period, the second time period, and the third time period are configured to be periodically distributed, with a combined duration covering the total duration of the inhalation process.

In an embodiment, within one cycle, durations of the first time period, the second time period, and the third time period are equal; or within one cycle, both the first time period and the second time period are less than one third of the total duration, while the third time period is greater than one third of the total duration.

An implementation solution provided by the method for solving the problems is similar to an implementation solution recorded in the above-mentioned electronic atomization device. Therefore, for specific limitations in one or more embodiments of the method for controlling an electronic atomization device provided below, reference may be made to the limitations on the electronic atomization device as above, which will not be repeated herein.

• • Step 610: Detect whether the electronic atomization device is in use for inhalation.
  • Step 620: Control a power module to supply energy to a heating element at a first preset power within a first time period and at a second preset power within a second time period during inhalation of the electronic atomization device, where the first preset power is less than the minimum atomization power corresponding to a first portion of an atomization substrate in the electronic atomization device, the second preset power is greater than or equal to the minimum atomization power corresponding to the first portion of the atomization substrate in the electronic atomization device, and the sum of the first time period and the second time period is less than or equal to a total duration of a single inhalation session of the electronic atomization device.

For an execution process of each step in this embodiment, reference may be made to the above-mentioned embodiments, and details are not described herein again.

According to the above-mentioned method for controlling an electronic atomization device, during inhalation of the electronic atomization device, at the beginning of inhalation, the amount of atomization substrate is relatively high. By heating the atomization substrate at the low first preset power first, the amount of atomization substrate near the heating element is reduced after which the device continues to raise the temperature at the second preset power, thereby avoiding a liquid spit-back phenomenon caused by rapid temperature rise and boiling of the second portion with low boiling point within the atomization substrate, enhancing the taste for a user during the inhalation process.

As an embodiment, the controlling a power module to supply energy to a heating element at a first preset power within a first time period and at a second preset power within a second time period during inhalation of the electronic atomization device includes:

• • controlling the power module to supply energy to the heating element at the first preset power within the first time period, at the second preset power within the second time period, and at a third preset power within a third time period during inhalation of the electronic atomization device.

The third preset power is less than the second preset power, and the sum of the first time period, the second time period, and the third time period is equal to the total duration of a single inhalation session of the electronic atomization device.

As an embodiment, the first preset power is less than or equal to the third preset power; or

• • the first preset power is greater than or equal to the third preset power.

As an embodiment, the third preset power is less than or equal to an average value of the first preset power and the second preset power.

As an embodiment, during a single inhalation process, the first time period, the second time period, and the third time period are configured to have a combined duration that covers the total duration of the inhalation process; or

during a single inhalation process, the first time period, the second time period, and the third time period are configured to be periodically distributed, with a combined duration of a plurality of cycles covering the total duration of the inhalation process.

As an embodiment, within one cycle, durations of the first time period, the second time period, and the third time period are equal; or within one cycle, both the first time period and the second time period are less than one third of the total duration, while the third time period is greater than one third of the total duration.

In an embodiment, the method includes: detecting an inhalation signal of the electronic atomization device; and

• • determining the first time period and the second time period according to the inhalation signal, and controlling the power module to supply energy to the heating element at the first preset power within the first time period and at the second preset power within the second time period.

As an embodiment, the first preset power is greater than or equal to the minimum atomization power corresponding to the second portion and less than the minimum atomization power corresponding to the first portion.

As an embodiment, when the total duration of a single inhalation session of the electronic atomization device is the same, the total power output by the electronic atomization device remains identical.
