The ceramic core tube 161 can absorb and store the atomized liquid for the heating wire 163 to heat and atomize. The liquid guiding cotton is in a central tube shape, is arranged on the inner wall surface of the ceramic core tube 161 and is used for guiding the liquid stored in the ceramic core tube 161 to the heating wire 163. The heating wire 163 in the flattened state is fixed in the ceramic core tube 161 as shown in fig. 3, and is in a wound state as shown in fig. 4 and 5. Specifically, the first heating portion 164A and the second heating portion 164B of the heating wire 163 are fixedly connected to the inner wall surface of the liquid-guiding cotton, the first heating portion 164A and the second heating portion 164B are disposed around, and the first heating portion 164A and the second heating portion 164B are connected to each other along the circumferential direction.

In other embodiments, the ventilation pipe B may not be a cylindrical channel, the ceramic core tube 161 and the liquid-guiding cotton may not be circular tubes, and the first heating portion 164A and the second heating portion 164B are fixedly connected to the inner wall surface of the liquid-guiding cotton and are disposed opposite to each other in the first direction at intervals.

Referring to fig. 2, the heating element 16 is inserted into the ventilation channel B from a side away from the suction nozzle 212, and is used for heating the atomized liquid to generate aerosol. Specifically, the ceramic core tube 161 is installed in the ventilation channel B of the liquid storage cotton, and the pin 165 of the heating wire 163 exposes one end of the ventilation channel B far away from the suction nozzle 212 and is electrically connected with the power supply. The ceramic core tube 161 is in contact with the liquid storage cotton, and guides the atomized liquid stored in the liquid storage cotton to the liquid guide cotton so as to heat the heating wire 163 arranged in the liquid guide cotton to generate aerosol. In this embodiment, the first heating portion 164A of the heating member 16 is disposed toward the first portion 15A of the liquid storage cotton, and the second heating portion 164B is disposed toward the second portion 15B of the liquid storage cotton. Wherein the first heating portion 164A and the second heating portion 164B are symmetrically disposed about the X-Y plane.

In this embodiment, the heating member 16 has a plurality of heating modes including a simultaneous heating mode, an alternate heating mode, and a separate heating mode. The simultaneous heating mode is a mode in which the first heating portion 164A and the second heating portion 164B are energized simultaneously to heat the atomized liquid together; the alternate heating mode is a mode in which the first heating portion 164A and the second heating portion 164B are alternately energized to alternately heat the atomized liquid; the individual heating mode is a mode in which the first heating portion 164A is energized, the second heating portion 164B is not energized, and the first heating portion 164A individually heats the atomized liquid. It will be appreciated that in the single heating mode, only the first heating portion 164A is energized and heat is primarily concentrated in the first portion 15A of the liquid storage cotton, so that the primary heating consumes the atomized liquid stored in the first portion 15A. The heating element 16 is connected to an electronic control assembly by which various heating modes of the heating element 16 can be switched.

Referring to fig. 2, the upper sealing member 12 is provided with a first through hole 121, and the first through hole 121 penetrates the upper sealing member 12 along the thickness direction of the upper sealing member 12.

The lower seal member 13 is further provided with a second through hole 132, and the second through hole 132 penetrates the lower seal member 13 and the boss 131 in the thickness direction of the lower seal member 13. The lower sealing member 13 is mounted on the opening of the liquid cup at the end far away from the suction nozzle 212, the second through hole 132 is communicated with the ventilation channel B, and the pin 165 of the heating wire 163 passes through the second through hole 132. The lower sealing member 13 is used for preventing the atomized liquid in the liquid storage cotton from leaking out of the opening of the liquid cup, and affecting the normal operation of the electric control assembly in the atomizing device 100. In the present embodiment, both the upper seal member 12 and the lower seal member 13 are made of a silicone material.

Referring to fig. 2, the bracket 30 and the electronic control assembly are both accommodated in the accommodating cavity and are located at an end of the atomizing assembly away from the suction nozzle 212. The boss 131 of the lower seal member 13 is inserted into the bracket 30.

The electronic control assembly includes a power supply 51, a main board 52, a control unit (not shown) and a microphone 53. The power supply 51 is fixedly connected to an inner wall surface of the casing 20 at an end facing away from the suction nozzle 212, and is electrically connected to the main board 52. The main board 52 is disposed between the bracket 30 and the bottom wall of the housing 20, and the main board 52 is electrically connected to the microphone 53 and the heating element 16 to supply power to the microphone 53 and the heating element 16. The microphone 53 is mounted and fixed to the bracket 30. The microphone 53 is an air pressure sensor and is used for detecting air flow to identify the sucking state. When a user sucks the atomizing device 100 provided in the present application, the microphone 53 can sense the flow of gas therethrough and transmit a suction instruction to the control unit. The control unit is integrated in the main board 52 and is electrically connected with the main board 52, and the control unit is electrically connected with the microphone 53 and the heating wire 163. The control unit can receive the suction instruction transmitted by the microphone 53 and count the number of times and the length of time of suction by the user based on the signal. The control unit is also capable of controlling the heating mode of the heating member 16.

Referring to fig. 6, fig. 6 is a flow chart of a heating control method of the atomizing device 100 provided in the present application.

The embodiment of the present application also provides a heating control method for the atomizing device 100, including:

in step S01, the microphone 53 acquires a suction instruction from the user.

Specifically, when the atomizing device 100 is sucked by the user, the microphone 53 detects that there is a gas flowing therethrough, that is, detects that the atomizing device 100 is in a sucking state, and sends a suction instruction to the control unit.

In step S02, the control unit obtains a liquid amount parameter concerning the atomized liquid according to the suction instruction.

And after receiving the suction instruction, the control unit acquires the liquid quantity parameters counted by the control unit. The fluid quantity parameter is the content of the atomized liquid remaining in the atomizing device 100, and the fluid quantity parameter can be obtained according to the number of times of pumping or the pumping duration of the user. The number of suctions means the cumulative number of times the control unit counts the user suctions the atomizing device 100 through the built-in counter; the suction period refers to the accumulated period of time for which the control unit sucks the atomizing device 100 by the user counted by the built-in timer. The more the number of puffs or the longer the period of puffs, the less the content of atomized liquid stored in the atomizing device 100, i.e. the smaller the liquid amount parameter. It will be appreciated that the number of puffs or the length of the puffs is positively correlated to the amount of nebulized liquid that has been consumed by the nebulizing device 100. Therefore, the amount of the atomized liquid consumed by the atomizing device 100 can be calculated by the number of times of suction or the suction time period, and thus the amount of the atomized liquid remaining in the atomizing device 100, that is, the liquid amount parameter can be obtained.

In step S03, the control unit controls the operation state of the heating element 16 according to the liquid amount parameter. The operating states of the heating element 16 include a first heating state, a second heating state, and a third heating state.

Referring to fig. 7, fig. 7 is a flowchart of a heating control method of the atomizing device 100 provided in the present application. In the present embodiment, step S03 includes steps S031 to S035.

Step S031, judging whether the liquid amount parameter is larger than the first liquid amount threshold, if yes, executing step S032, otherwise, executing step S033.

Specifically, the atomizing device 100 has a predetermined capacity, i.e., the content of the atomized liquid stored in the atomizing device 100 in an unconsumed state. The fluid quantity parameter is less than the predetermined capacity. In this embodiment, the first liquid amount threshold is 20% or more and 40% or less of the predetermined capacity. The first liquid amount threshold may be, for example, 20% or 25% or 30% of the predetermined capacity. If the fluid volume parameter of the atomizing device 100 is greater than the first fluid volume threshold, it is indicated that the amount of atomized fluid stored in the atomizing device 100 is sufficient to support the operation of the heating element 16 in the first heating state.

In step S032, the control unit controls the heating element 16 to enter the first heating state.

The control unit controls the heating member 16 to enter the first heating state. The first heating state may be that the corresponding heating portion of the heating member 16 is operated in the simultaneous heating mode; or the corresponding heating portions of the heating member 16 are operated in the alternate heating mode; or in the process that the corresponding heating parts of the heating piece 16 work in the alternating heating mode, after each time the microphone 53 obtains a suction instruction, a process that at least two heating parts work simultaneously exists; or the corresponding heating portions of the heating member 16 are operated in the simultaneous heating mode first and then in the alternate heating mode; or the corresponding heating portions of the heating member 16 are operated in the alternating heating mode first and then in the simultaneous heating mode.

If the corresponding heating portions of the heating element 16 are in the simultaneous heating mode, the control unit controls the first heating portion 164A and the second heating portion 164B to operate simultaneously, and at this time, the output powers of the first heating portion 164A and the second heating portion 164B are superimposed, so as to realize high-power heating of the atomizing assembly, and significantly improve the TPM value (Total Particulate Matter ) of the atomizing device 100, so that the user has a stronger sense of bursting when sucking the atomizing device 100; and under the simultaneous heating mode, the first heating portion 164A and the second heating portion 164B are both in the rated working condition, and can keep a stable load state to support the sucking of the user, so that the sucking resistance of the atomizing device 100 is more stable, and the experience of the user sucking the atomizing device 100 is better.

If the heating element 16 is in the alternative heating mode, the control unit controls the first heating portion 164A and the second heating portion 164B to alternately operate each time when the microphone 53 obtains a pumping instruction, so that each heating portion 164 can be sufficiently cooled after heating, a carbon deposition phenomenon caused by long-time continuous operation of the single heating portion 164 is avoided, the stability of the aerosol sucking taste is remarkably improved, and the sustainable operating time of the atomizing device 100 is prolonged. Wherein, the control unit may switch the first heating part 164A and the second heating part 164B to alternately operate according to the pumping instruction. For example, after the control unit acquires the suction instruction last time, the control unit controls the first heating portion 164A to perform the independent heating (for example, 1.5 s), and after the control unit acquires the suction instruction this time, the control unit switches to the second heating portion 164B to perform the independent heating (for example, 1.5 s), and if the control unit continues to acquire the suction instruction next time, the control unit continues to switch to the first heating portion 164A to perform the independent heating (for example, 1.5 s).

If the corresponding heating portions of the heating member 16 are operated in the alternate heating mode, there is a process in which at least two heating portions are simultaneously operated after each suction instruction is acquired by the microphone 53. For example, after the control unit acquires the suction instruction last time, the control unit controls the first heating portion 164A to perform heating (for example, 1.5 s), and after the control unit acquires the suction instruction this time, the control unit switches to the second heating portion 164B to perform independent heating (for example, 1.5 s), and if the control unit continues to acquire the suction instruction next time, the control unit switches to the first heating portion 164A to perform independent heating (for example, 1.5 s). In this process, each time the first heating portion 164A heats, the second heating portion 164B also heats simultaneously, and the predetermined period of time may be in a range of 0.4 seconds or more and 0.6 seconds or less. For example, each time the first heating portion 164A is operated for 1.5s, the second heating portion 164B is also operated for 0.5s simultaneously, and then the second heating portion 164B continues to be operated separately for 1s after the next suction instruction is acquired; when the suction instruction is again acquired, the first heating portion 164A is operated for 1.5s, and the second heating portion 164B is also operated for 0.5s … … at the same time, so that the cycle is repeated. That is, compared with the alternative heating mode described above, the present embodiment adopts a similar alternative heating mode, but the first heating portion 164A is not yet completely operated, and the second heating portion 164B and the first heating portion 164A participate in heating, and after the next suction, the second heating portion 164B alternately heats. In this way, in the two adjacent suction processes, the heating portions work cooperatively, and the continuous and smooth progress of the heating process of the heating member 16 can be ensured.

If the heating element 16 is in the simultaneous heating mode and then in the alternating heating mode, or if the heating element 16 is in the alternating heating mode and then in the simultaneous heating mode. The control unit controls the heating piece 16 to switch heating modes, so that a user can experience different aerosol sucking tastes under different heating modes when sucking the atomizing device 100 provided by the embodiment of the application, and the sucking experience of the user is enriched. In this embodiment, the first heating state of the heating element 16 means that the first heating portion 164A and the second heating portion 164B are in the simultaneous heating mode for a predetermined period of time (e.g. 0.5 s), and then in the alternating heating mode (e.g. the first heating portion 164A and the second heating portion 164B work for 1s in turn). The predetermined duration may range from 0.4 seconds or more to 0.6 seconds or less. For example, the predetermined time period may be 0.5 seconds, i.e., the first heating portion 164A and the second heating portion 164B are operated simultaneously for 0.5 seconds and then are operated alternately.

Step S033, judging whether the liquid amount parameter is greater than the second liquid amount threshold, if yes, executing step S034, otherwise, executing step S035.

Specifically, the second fluid volume threshold is less than the first fluid volume threshold. In this embodiment, the second liquid amount threshold is 2% or more and 10% or less of the predetermined capacity. The second liquid amount threshold may be, for example, 5% of the predetermined capacity. If the fluid volume parameter of the atomizing device 100 is less than the first fluid volume threshold and greater than the second fluid volume threshold, then this indicates that the amount of atomized fluid stored within the atomizing device 100 is less than sufficient to support continued operation of the heating element 16 in the first heating state.

In step S034, the control unit controls the heating element 16 to enter the second heating state.

The control unit controls the heating member 16 to enter the second heating state. The second heating state means that the corresponding heating portion of the heating member 16 operates in the individual heating mode.

Because the atomization device 100 provided in the embodiment of the application is in an asymmetric structure, the ventilation channel B of the liquid storage cotton is eccentrically arranged, the volume of the first portion 15A is larger than that of the second portion 15B, and the volume of the atomized liquid stored in the first portion 15A is also larger than that of the atomized liquid stored in the second portion 15B. When the amount of the atomized liquid stored in the atomizing device 100 is smaller, the amount of the atomized liquid stored in the second portion 15B with smaller volume is smaller, so that the situation that the atomized liquid is not supplied is easier to occur, and the dry heating condition of the second heating portion 164B affects the sucking experience of the user. Therefore, when the amount of the atomized liquid stored in the atomizing device 100 is small, that is, when the liquid amount parameter of the atomizing device 100 is greater than the second liquid amount threshold and less than the first liquid amount threshold, the heating member 16 enters the second heating state. At this time, only the first heating portion 164A is energized in the heating member 16, and the heat is mainly concentrated on the first portion 15A of the liquid storage cotton, so that the atomized liquid stored in the first portion 15A is mainly consumed by heating. The first portion 15A stores more atomized liquid than the second portion 15B, and the first heating portion 164A is not dry-burned temporarily. Therefore, in the suction rear section of the atomization device 100, the content of the atomized liquid is small, and the heating piece 16 is only used for heating the liquid storage cotton area with a large volume, so that the problem that the heating wire 163 of the asymmetric atomization device 100 is dry-burned and carbon deposited due to uneven distribution of the atomized liquid is solved, and the consistency of the suction taste of the asymmetric atomization device 100 is remarkably improved.

In step S035, the control unit controls the heating element 16 to enter the third heating state.

The third heating state refers to that the heating element 16 is not operated, that is, neither the first heating portion 164A nor the second heating portion 164B is operated.

If the liquid amount parameter of the atomizing device 100 is smaller than the second liquid amount threshold, it indicates that the amount of the atomized liquid stored in the atomizing device 100 is already very small enough to support the heating element 16 to continue to operate in the second heating state, and therefore, step S035 is performed to control the heating element 16 to enter the third heating state. When the amount of the atomized liquid stored in the atomizing device 100 is very small, even if the heating member 16 is in the second heating state, only the atomized liquid stored in the first portion 15A is heated, there is a problem that the supply of the atomized liquid is insufficient and the taste of the aerosol is deteriorated. Therefore, after the liquid amount parameter of the atomizing device 100 is less than or equal to the second liquid amount threshold, although the atomized liquid in the atomizing device 100 may not be exhausted yet, the control unit controls the heating element 16 to enter the third heating state, i.e. the stop working state, so as to avoid the poor sucking experience for the user. Meanwhile, the control unit can also control a prompting device, such as an electronic element such as a display component, a buzzer or a vibration motor, to send out a prompting signal to remind a user that the content of atomized liquid is low, the atomization device 100 can not be used continuously, and the user can be required to replace in time.

In step S04, the microphone 53 acquires a suction stop instruction from the user.

Specifically, when the user finishes sucking the atomizing device 100, the microphone 53 detects that no gas passes around, that is, detects that the atomizing device 100 is no longer in a sucking state, so that a suction stop instruction is sent to the control unit, and the control unit acquires the suction stop instruction of the atomizing device 100.

In step S05, the heating member 16 is controlled to stop heating.

The control unit stops the power supply to the heating element 16 to bring the heating element 16 into a stopped heating state, based on the received suction stop instruction or based on a determination that the liquid amount parameter of the atomizing device 100 is smaller than the second liquid amount threshold.

In some embodiments, the heating control method for the atomizing device may not include step S04 and step S05.

In other embodiments, the control unit is also capable of acquiring the operating voltage of the atomizing device 100 and adjusting the operating state of the atomizing device 100 based on the operating voltage. Specifically, after the control unit obtains the working voltage of the atomizing device 100, the working voltage is compared with the first voltage, and if the working voltage is greater than the first voltage, the control unit controls the atomizing device 100 to enter a limiting state and continues for a preset time. If the operating voltage is less than the first voltage, the control unit does not control the atomizing device 100.

When the atomizing device 100 is in the limiting state, the operating voltage of the atomizing device 100 is fixedly limited to the second voltage. Wherein the second voltage is less than the first voltage. For example, the first voltage may be 3.7V, the second voltage may be 3.6V, the preset time may be 30 times of pumping, and in other embodiments, the first voltage, the second voltage, or the preset time may be other values, without being limited thereto. The control unit may acquire the operating voltage of the atomizing device 100 again after controlling the atomizing device 100 to enter the limiting state and continuously for a preset time, and repeat the above steps until the operating voltage of the atomizing device 100 is less than the first voltage.
