[0028] Some embodiments of the atomization device provided in the present disclosure are described below with reference to the accompanying drawings.

[0064] In a further embodiment of the present disclosure, as shown in FIG. 14, an atomization device provided in this embodiment includes a heating module 10 and a power supply device 20; where the heating module 10 includes a second electronic control element 13a and a heating element 11a, and the second electronic control element 13a is configured to supply power to the heating element 11a according to a preset program when a heating signal is triggered to control the heating of the heating element 11a; and the heating element 11a is electrically connected to the second electronic control element 13a, and the heating element 11a is configured to heat an aerosol-generating substrate 30 under the control of the second electronic control element 13a.

[0065] The power supply device 20 is detachably connected to the heating module 10, the power supply device 20 includes a first electronic control element 23a and a battery 21a, and the battery 21a is configured to supply power to the first electronic control element 23a; and the first electronic control element 23a is electrically connected to the second electronic control element 13a, the first electronic control element 23a is configured to supply power to the second electronic control element 13a, and the first electronic control element 23a is further configured to send a heating signal to the second electronic control element 13a according to the user's instruction.

The heating signal sent by the first electronic control element 23a to the second electronic control element 13a is an alternating level signal. Moreover, during heating, due to a relatively large resistance between pogo pins 22a, when the first electronic control element 23a serves as a main control board, a contact resistance between the pogo pin 22a and a copper pillar 12a affects the normal heating of the heating element 11a during a heating control process, which results in reduced heating efficiency; and therefore, in this solution, the second electronic control element 13a as the main control board controls the heating of the heating element 11a.

[0067] Furthermore, for the heating module 10, a heat insulation component (such as a heat insulation foam or a heat insulation plate) may be further disposed between the heating element 11a and the second electronic control element 13a to ensure that a temperature of the second electronic control element 13a is always lower than 85°C during the heating process, which not only ensures the normal operation of the second electronic control element 13a, but also prolongs its service life.

[0068] The atomization device of this embodiment enables communication between split-type atomization devices and precise temperature-controlled heating, which meets high adaptability of the aerosol-generating substrates 30 of different specifications to the device, and effectively improves a utilization rate of the device. A method of communication between the heating module 10 and the power supply device 20 adopted in the present disclosure ensures that the power supply device 20 performs temperature control of a heating element in the heating module 10, identifies differences between different modules, and maintains the normal operation of a modular heat-not-burn (HNB) device.

[0069] In some embodiments, as shown in FIGS. 15 and 16, the power supply device 20 further includes a sensor 24a; the sensor 24a is electrically connected to the first electronic control element 23a; the sensor 24a is configured to generate an air pressure signal after an inhalation action; and the first electronic control element 23a is further configured to send a heating signal to the second electronic control element 13a when the air pressure signal is triggered.

[0070] In practical applications, the sensor 24a is a microphone. Specifically, when a preset duration of heating expires, the user is reminded to start inhaling, each time when the user performs an inhalation action, an air pressure signal generated by the sensor 24a changes, and in this case, the first electronic control element 23a, after sensing the air pressure change, sends a heating signal to the second electronic control element 13a, and the second electronic control element 13a adjusts a current input to the heating element 11a according to the heating signal, to adjust the temperature of the heating element 11a at different moments.

[0071] Furthermore, in some embodiments, the atomization device further includes a plurality of pogo pins 22a and a plurality of copper pillars 12a arranged in correspondence with the pogo pins 22a; where the pogo pins 22a are disposed on the power supply device 20, and the pogo pins 22a are connected to the first electronic control element 23a; the copper pillars 12a are disposed on the heating module 10, and the copper pillars 12a are connected to the second electronic control element 13a; and the first electronic control element 23a achieves communication and / or power supply with the second electronic control element 13a through the pogo pins 22a and the copper pillars 12a. Alternatively, the pogo pins 22a may be disposed on the heating module 10, and the pogo pins 22a are connected to the second electronic control element 13a; the copper pillars 12a are disposed on the power supply device 20, and the copper pillars 12a are connected to the first electronic control element 23a; and the first electronic control element 23a achieves communication and / or power supply with the second electronic control element 13a through the pogo pins 22a and the copper pillars 12a.

[0072] As shown in FIGS. 15 and 16 in this embodiment, it can be seen that the heating module 10 and the power supply device 20 rely on the pogo pins 22a for power supply and communication. Specifically, in this solution, four pogo pins 22a are disposed on the power supply device 20, four copper pillars 12a are disposed on the heating module 10 at positions corresponding to the pogo pins 22a, and during use, three pogo pins 22a and three copper pillars 12a are combined for power supply, and one pogo pin 22a and one copper pillar 12a are combined for communication. Alternatively, the pogo pins 22a are disposed on the heating module 10, and the copper pillars 12a are disposed on the power supply device 20 at positions corresponding to the pogo pins 22a, with the same operating principle. Additionally, the number of the pogo pins 22a-the copper pillars 12a is at least 2, generally ranging from 2 to 16.

[0073] It should be noted that a connection structure of the pogo pins 22a-the copper pillars 12a may also be replaced with any other pluggable connector, such as a terminal block connection structure, a pin header socket connection structure, or a threaded connection structure. This connection structure not only achieves communication between the heating module 10 and the power supply device 20, but also ensures power supply to the heating element 11a.

[0074] In some embodiments, as shown in FIG. 14, the power supply device 20 further includes a display unit 25, and the display unit 25 is electrically connected to the first electronic control element 23a; and the first electronic control element 23a is further configured to receive and process a display signal sent by the second electronic control element 13a, and to send the processed display signal to the display unit 25 for display.

[0075] Specifically, the display unit 25 is a display screen, and during operation, to help the user to keep abreast of a current usage status of the device at any time, the second electronic control element 13a sends a display signal to the first electronic control element 23a at different stages of the heating process (e.g., a signal reminding the user to start inhaling when a preset duration of heating expires). The signal is processed by the first electronic control element 23a and displayed through the display unit 25 to remind the user of the current usage status.

[0076] In some embodiments, as shown in FIG. 14, the power supply device 20 is further provided with a key 26, the key 26 is electrically connected to the first electronic control element 23a, the user's instruction is transmitted to the second electronic control element 13a through the key 26, and then the first electronic control element 23a transmits the instruction to the second electronic control element 13a to perform a corresponding operation. For example, pressing once represents an instruction to start the device, and pressing twice in succession represents an instruction to start heating.

[0077] Furthermore, as a heating stop control method, the first electronic control element 23a is provided with a preset heating duration or a preset number of inhalations; and when a heating duration of the heating element 11a reaches the preset heating duration, the first electronic control element 23a sends a heating stop signal to the second electronic control element 13a. Alternatively, when the number of generated air pressure signals reaches the preset number of inhalations, the first electronic control element 23a sends a heating stop signal to the second electronic control element 13a.

[0078] Specifically, before delivery of the atomization device, the first electronic control element 23a is provided with the preset heating duration or the preset number of inhalations; during use by the user after delivery, when a temperature-controlled heating duration reaches a total preset heating duration, the first electronic control element 23a sends a heating stop signal to the second electronic control element 13a; and in this case, the second electronic control element 13a stops supplying power to the heating element 11a after receiving the signal. Alternatively, the first electronic control element 23a is provided with a counter, the counter records the number of heating signals received from the sensor 24a, when the number of heating signals reaches the preset number of inhalations, the first electronic control element 23a sends a heating stop signal to the second electronic control element 13a, and in this case, the second electronic control element 13a stops supplying power to the heating element 11a after receiving the signal, and the device stops heating.

[0079] As another heating stop control method, the second electronic control element 13a is provided with a preset heating duration or a preset number of heating counts, and when a heating duration of the heating element 11a reaches the preset heating duration, the second electronic control element 13a controls the heating element 11a to stop heating. Alternatively, when the number of heating signals sent by the first electronic control element 23a to the second electronic control element 13a reaches the preset number of heating counts, the second electronic control element 13a controls the heating element 11a to stop heating.

[0080] Specifically, before delivery of the atomization device, the second electronic control element 13a is provided with a preset heating duration or a preset number of heating counts, and during use by the user after delivery, when a temperature-controlled heating duration reaches a total preset heating duration according to the preset program, the second electronic control element 13a stops supplying power to the heating element 11a. Alternatively, the first electronic control element 13a is provided with a counter, the counter records the number of heating signals received from the first electronic control element 23a, when the number of heating signals reaches the preset number of heating counts, the second electronic control element 13a stops supplying power to the heating element 11a, and the device stops heating.

[0081] Another atomization device provided in this embodiment includes a heating module 10 and a power supply device 20; the heating module 10 includes a second electronic control element 13a and a heating element 11a; where the second electronic control element 13a is configured to store a heating parameter of the heating element 11a; the heating element 11a is configured to heat an aerosol-generating substrate 30; the power supply device 20 is detachably connected to the heating module 10, and the power supply device 20 includes a first electronic control element 23a and a battery 21a, where the battery 21a is configured to supply power to the first electronic control element 23a; and the first electronic control element 23a is electrically connected to the second electronic control element 13a and the heating element 11a respectively, and the first electronic control element 23a is configured to obtain the heating parameter from the second electronic control element 13a and supply power to the heating element 11a according to the heating parameter, so as to control the heating of the heating element 11a.

[0082] For the atomization device of this embodiment, when a memory space of the second electronic control element 13a is small, the second electronic control element 13a only serves as a memory chip, and the first electronic control element 23a serves as the main control board to control the heating of the heating element 11a. Specifically, the second electronic control element 13a acquires and stores a heating parameter of the heating element 11a in real time, where the heating parameter is an intrinsic parameter of the heating element 11a, mainly including a resistance, a temperature, a corresponding relationship between the resistance and the temperature of the heating element 11a. For example, an increase in the resistance of the heating element 11a when the temperature of the heating element 11a rises by 1°C (which may be calculated by the temperature coefficient of resistance (TCR) formula) is read. Since the second electronic control element 13a is in communication connection with the first electronic control element 23a, the second electronic control element 13a is capable of sending an acquired heating parameter to the first electronic control element 23a, and the first electronic control element 23a determines a corresponding heating curve according to the heating parameter, and then supplies the corresponding current to the heating element 11a, to achieve temperature-controlled heating of the aerosol-generating substrate 30. Additionally, similar to the above embodiments, the first electronic control element 23a is also powered by the battery 21a, and the second electronic control element 13a is powered through the first electronic control element 23a.

In this case, it is necessary to ensure that a contact resistance of the pogo pin 22a-copper pillar 12a structure during heating is not greater than 50 milliohms, so as to ensure that heat loss remains within an expected range.
