[0030] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0031] See also Figure 1 , Figure 1 A flow chart of a method for controlling the heating mode of an atomizer component provided in one embodiment of the present application; in this embodiment, a method for controlling the heating mode of an atomizer component is provided, and the method can promptly determine whether the aerosol-forming matrix in the atomizer component is completely baked, and terminate the heating in time, so as to avoid the problem of the user continuing to inhale and inhaling a burnt smell after the aerosol-forming matrix is ​​completely baked, and at the same time ensure that the user inhales a sufficient amount of smoke each time, so as to improve the user experience.

[0032] Specifically, the method includes:

[0033] Step S11: obtaining a first temperature of a first preset position of the atomization assembly through a first temperature collector.

[0034] For details, see Figure 2 , Figure 2 A schematic diagram of the structure of an atomizer assembly provided in an embodiment of the present application; in one embodiment, the atomizer assembly 10 includes an atomizer cavity 11 and a heating element (not shown), wherein the atomizer cavity 11 defines an atomizer cavity 111, and the atomizer cavity 111 is used to accommodate an aerosol-forming matrix; and the atomizer cavity 11 has an air inlet 112 and an air outlet 113, and the air inlet 112 and the air outlet 113 of the atomizer cavity 11 correspond to the two ends of the atomizer cavity 111, respectively, so that the outside air can It flows through the atomizing chamber 111 through the air inlet 112 and then flows out from the air outlet 113; in a specific embodiment, the air inlet 112 of the atomizing chamber 11 is arranged on the bottom wall 114 of the atomizing chamber 11, and the air outlet 113 is arranged on the top wall 115 of the atomizing chamber 11; the heating element is used to heat and atomize the aerosol-forming matrix when powered on; in the specific implementation process, the heating method can be heating by heating the cavity wall of the atomizing chamber 11 and / or heating by the airflow flowing through the atomizing chamber 111.

[0035] Among them, the first preset position of the atomizer assembly 10 specifically corresponds to the position of the air outlet 113 of the atomizer assembly 10, that is, the first temperature collector 12 collects the temperature of the position of the air outlet 113 of the atomizer assembly 10; wherein, the first temperature collector 12 can specifically be a temperature sensor; in a specific embodiment, the temperature sensor can be specifically set at the first preset position of the atomizer assembly 10 to sense and collect the first temperature at this position.

[0036] In the specific implementation process, the first temperature may be the real-time temperature after heating for a certain period of time, that is, during the initial heating process, the heating state of the aerosol-forming matrix in the atomization assembly 10 is not determined, nor is its heating mode controlled to reduce the program running pressure.

[0037] Step S12: obtaining the temperature difference between the first temperature and the second temperature through the controller.

[0038] Before step 12, the second temperature is also acquired, and the second temperature is specifically the temperature of the second preset position of the atomizer assembly 10. The first temperature and the second temperature are specifically the temperatures of the first preset position and the second preset position of the atomizer assembly 10 at the same time.

[0039] In one specific embodiment, see Figure 3 and Figure 4 ,in, Figure 3 A schematic diagram of the positions of the first temperature collector and the second temperature collector on the atomization chamber provided in one embodiment of the present application; Figure 4 A schematic diagram of the positions of the first temperature collector and the second temperature collector on the atomization chamber provided in another embodiment of the present application; the second temperature collector 13 can be used to obtain the second temperature at the second preset position of the atomization assembly 10; wherein the second temperature collector 13 can be specifically a temperature sensor, which can be specifically arranged at the second preset position of the atomization assembly 10 for sensing and collecting the second temperature at the second preset position of the atomization assembly 10; wherein the second preset position can be specifically a position close to the heating device; in a specific embodiment, the second preset position can be the position where the air inlet 112 of the atomization assembly 10 is located (see Figure 3 ) or other positions different from the air inlet 112 and the air outlet 113, for example, the side wall 116 of the atomizing chamber 11. In this embodiment, the second temperature collector 13 can be specifically arranged on the side wall 116 of the atomizing chamber 11 and located near the bottom wall 114 (see Figure 4 ). The heating device is used to heat and atomize the aerosol-forming matrix when powered on; specifically, the heating device can be a heating element.

[0040] In another specific embodiment, the specific heat capacity, mass and current heat data of the atomizer assembly 10 can also be obtained by a controller (not shown), and then the second temperature can be calculated according to the specific heat capacity, mass and current heat data of the atomizer assembly 10; specifically, the second temperature can be calculated according to the specific heat capacity formula; wherein the specific heat capacity formula is as follows:

[0041]

[0042] Wherein, c is the specific heat capacity of the atomizing chamber 11 , m is the mass of the atomizing chamber 11 , Q is the heat, t is the final temperature of the atomizing chamber 11 , and t0 is the initial temperature of the atomizing chamber 11 .

[0043] Specifically, after the atomizing chamber 11 is heated for T time with power P in advance, the temperature difference before and after the heating of the atomizing chamber 11 is obtained, and then the specific heat capacity c corresponding to the current atomizing chamber 11 is obtained according to the formula Q=P·T and the above-mentioned specific heat capacity formula; it can be understood that in the specific implementation process, the specific heat capacity c value, the mass m of the atomizing chamber 11 and the initial temperature t0 value of the atomizing chamber 11 are all known data. In the specific implementation process, it is only necessary to record the heating time T, and calculate the heat Q according to the current heating power P, and then substitute it into the specific heat capacity formula to obtain the temperature value t, which is the second temperature.

[0044] The temperature difference between the first temperature and the second temperature specifically refers to the difference between the first temperature and the second temperature obtained at the current moment; for example, at moment T1, the first temperature obtained is t1 and the second temperature is t2. At this time, the temperature difference between the two is t1-t2.

[0045] Step S13: comparing the temperature difference with a preset temperature difference and determining the heating state of the aerosol-forming substrate in the atomizing assembly according to the comparison result.

[0046] Wherein, the heating state may include completed heating and uncompleted heating. In the specific implementation process, step S13 specifically includes determining whether the temperature difference is greater than the preset temperature difference; if the temperature difference is greater than the preset temperature difference, the heating state of the aerosol-forming matrix in the atomizing component 10 is determined to be uncompleted heating; if the temperature difference is not greater than the preset temperature difference, that is, the temperature difference is less than or equal to the preset temperature difference, the heating state of the aerosol-forming matrix in the atomizing component 10 is determined to be completed heating; in the specific implementation process, when the heating state is determined to be completed heating, a control signal is output through the controller at the same time; wherein the control signal at least includes a power-off signal to disconnect the electrical connection of the atomizing component 10, thereby terminating heating; of course, in other embodiments, the control signal may also include a prompt signal to remind the user that the active ingredients in the current aerosol-forming matrix have been completely roasted, so that the user can take corresponding actions in time, such as stopping the suction in time to prevent the suction from burning smell; wherein the reminder signal may be one or more of an audio-visual prompt, a vibration prompt, and a voice prompt.

[0047] Specifically, the difference range of the preset temperature difference can be 3-10. It should be noted that during the heating process of the atomizer assembly 10, as the heating time increases, the temperature difference at the positions of the air inlet 112 and the air outlet 113 of the atomizer cavity 11 changes from large to small, and finally approaches the same, that is, when the effective ingredients in the aerosol-forming matrix are completely roasted, the first temperature and the second temperature approach the same.

[0048] Step S14: controlling the heating mode according to the heating state of the aerosol-forming substrate in the atomizing assembly, so that when the heating state is heating completion, the heating mode is controlled to be a non-heating mode.

[0049] In one specific embodiment, see Figure 4 Step S14 specifically includes, when the heating state of the aerosol-forming matrix in the atomization component 10 is completed, controlling the current heating mode to be a non-heating mode according to the control signal, so that after the aerosol-forming matrix is ​​completely baked, the heating can be terminated in time, so as to avoid the problem of the user continuing to inhale and inhaling a burnt smell after the aerosol-forming matrix is ​​completely baked, and at the same time, it can ensure that the user inhales a sufficient amount of smoke each time, so as to improve the user experience.

[0050] When the heating state of the atomizer assembly 10 is incomplete heating, the difference between the temperature difference and the preset temperature difference is further obtained through the controller, and then the theoretical electric power value of the atomizer assembly 10 is determined according to the difference; thereafter, the current electric power value of the atomizer assembly 10 is adjusted according to the theoretical electric power value, that is, the current electric power value is adjusted to the corresponding theoretical electric power value, so as to control the heating power at any time, thereby avoiding overheating and burning the aerosol to form a matrix, and avoiding the problem of scalding the user due to too high heating power in the later stage of heating. It should be noted that each difference corresponds to a theoretical electric power value, and the corresponding relationship can be preset in advance according to the actual situation; for example, when the difference is 50, the corresponding theoretical electric power value can be 200 watts, then the current heating electric power value can be adjusted to 200 watts; when the difference is 30, the corresponding theoretical electric power value is 150 watts, then the current heating electric power value can be adjusted to 150 watts.

[0051] Furthermore, in a specific embodiment, when the heating state of the atomizer assembly 10 is incomplete heating, after the step of obtaining the difference between the temperature difference and the preset temperature difference, the controller can further determine the remaining number of puffs of the atomizer assembly 10 based on the difference, and then remind the user of the remaining number of puffs of the current atomizer assembly 10 through voice broadcast or vibration times, so that the user can choose the number of puffs to continue puffing according to the remaining number of puffs, thereby avoiding the problem of the user inhaling a burnt smell or a small amount of smoke in the later stage of puffing; it can be understood that each difference corresponds to the remaining number of puffs of an atomizer assembly 10, and the corresponding relationship can be preset in advance according to actual conditions; for example, when the difference is 50, the corresponding remaining number of puffs can be 50; when the difference is 30, the corresponding remaining number of puffs can be 30.

[0052] The method for controlling the heating mode of the atomizer assembly provided in the present embodiment obtains the first temperature of the first preset position of the atomizer assembly 10 through the first temperature collector 12, and compares the temperature difference between the first temperature and the second temperature with the preset temperature difference through the controller to determine the heating state of the aerosol-forming substrate in the atomizer assembly 10, and then controls the heating mode of the aerosol-forming substrate in the atomizer assembly 10 based on the determined heating state of the aerosol-forming substrate in the atomizer assembly 10 through the controller, so that when the heating state is the heating completion state, the heating mode is controlled to be the non-heating mode, thereby terminating the heating of the aerosol-forming substrate in the atomizer assembly 10; compared with the solution in the prior art that determines and terminates the heating based on the user's taste, the method can be used in the following aspects: After the aerosol-forming matrix is ​​baked, the heating is terminated in time to avoid the problem of the user continuing to inhale and tasting the burnt smell after the aerosol-forming matrix is ​​completely baked, while ensuring that the user inhales enough smoke each time to improve the user experience; at the same time, since the first temperature collector 12 collects the temperature of the position of the air outlet 113 of the atomizer component 10, the second temperature is the temperature of the atomizer component 10 different from the temperature of the position of the air outlet 113, by comparing the temperature of the position of the air outlet 113 of the atomizer component 10 with the temperatures at other positions to determine the heating state of the aerosol-forming matrix in the atomizer component 10, the accuracy of determining the heating state of the aerosol-forming matrix in the atomizer component 10 can be greatly improved.

[0053] Please continue reading Figure 2 In this embodiment, an atomizer assembly 10 is provided. The atomizer assembly 10 is used to heat and atomize an aerosol-forming substrate contained therein when powered on to form smoke for the user to inhale; wherein the aerosol-forming substrate can be specifically tobacco, and the atomizer assembly 10 can be specifically used in an electronic cigarette device. Specifically, the atomizer assembly 10 includes an atomizer cavity 11, a heating element (not shown), a first temperature collector 12, and a controller (not shown).

[0054] Among them, the atomizing cavity 11 is limited to form an atomizing cavity 111, and the atomizing cavity 111 is used to accommodate an aerosol-forming matrix; and the atomizing cavity 11 has an air inlet 112 and an air outlet 113, and the air inlet 112 and the air outlet 113 of the atomizing cavity 11 respectively correspond to the two ends of the atomizing cavity 111, so that the outside air can flow through the atomizing cavity 111 through the air inlet 112, and then flow out from the air outlet 113; in a specific embodiment, the air inlet 112 of the atomizing cavity 11 is arranged on the bottom wall 114 of the atomizing cavity 11, and the air outlet 113 is arranged on the top wall 115 of the atomizing cavity 11.

[0055] Among them, the heating element is used to heat and atomize the aerosol to form a matrix when powered on; in the specific implementation process, the heating method can be through cavity wall heating of the atomization cavity 11 and / or air flow heating; specifically, the heating element can be a heating film.

[0056] The first temperature collector 12 is disposed at a first preset position of the atomizing chamber 11, and is used to obtain a first temperature of the first preset position of the atomizing chamber 11; wherein the first preset position corresponds to the position of the air outlet 113 of the atomizing chamber 11. Specifically, the first temperature collector 12 may be a temperature sensor, and the working principle of the temperature sensor includes but is not limited to thermocouple, NTC, PT1000 and the like.

[0057] Among them, the controller is connected to the first temperature collector 12, and is used to obtain the temperature difference between the first temperature and the second temperature; the temperature difference is compared with the preset temperature difference and the heating state of the aerosol-forming matrix in the atomization component 10 is determined according to the comparison result; wherein the second temperature is the temperature of the second preset position of the atomization cavity 11; the heating state includes completed heating and incomplete heating.

[0058] In one specific embodiment, see Figure 3 and Figure 4 The atomization assembly 10 also includes a second temperature collector 13 connected to the controller; the second temperature collector 13 is set at a second preset position of the atomization chamber 11, and can be used to obtain a second temperature and send the second temperature to the controller; wherein the second preset position is different from the first preset position, and the second preset position can be a position close to the heating element; in a specific embodiment, the second preset position can be specifically the position of the air inlet 112 of the atomization chamber 11 or other positions different from the air inlet 112 and the air outlet 113.

[0059] In another specific embodiment, the controller is also used to obtain the specific heat capacity, mass and current heat data of the atomization chamber 11 and calculate the second temperature based on the specific heat capacity, mass and current heat data of the atomization chamber 11; the specific calculation method can be found in the relevant text description involved in the above embodiment, which will not be repeated here.

[0060] Furthermore, the controller is also used to determine whether the temperature difference is greater than a preset temperature difference; if the temperature difference is greater than the preset temperature difference, it is determined that the heating state of the aerosol-forming substrate in the atomization component 10 is incomplete heating; if the temperature difference is not greater than the preset temperature difference, that is, the temperature difference is less than or equal to the preset temperature difference, it is determined that the heating state of the aerosol-forming substrate in the atomization component 10 is completed heating.

[0061] In a specific embodiment, when it is determined that the heating state is completed, the controller is also used to output a control signal; wherein the control signal at least includes a power-off signal to disconnect the electrical connection of the atomization component 10, thereby terminating the heating; of course, in other embodiments, the control signal may also include a prompt signal to remind the user that the effective ingredients in the current aerosol-forming matrix have been completely roasted, so that the user can take corresponding actions in time, such as stopping inhaling in time to prevent the smell of burning; wherein the reminder signal may be one or more of an audio-visual prompt, a vibration prompt, and a voice prompt.

[0062] The controller is also used to control the heating mode according to the heating state of the aerosol-forming substrate in the atomizing assembly 10, so that when the heating state is heating completed, the heating mode is controlled to be a non-heating mode. Specifically, the controller may be a processor.
