1 to 3 , the aerosol generating device 100 includes a first heating component 10, a second heating component 20, a housing 30 and a battery core 40. The housing 30 contains the first heating component 10, the second heating component 20 and the battery core 40, and the battery core 40 is used to provide the first heating component 10 and the second heating component 20 with the electrical power required for operation.

The first heating component 10 is used to heat a first aerosol-forming substrate to generate a first aerosol. The first aerosol-forming substrate includes a solid aerosol-forming substrate. The first aerosol-forming substrate can be an aerosol-generating product 201, such as a cigarette. The second heating component 20 is used to heat a second aerosol-forming substrate to generate a second aerosol. The second aerosol-forming substrate includes a liquid aerosol-forming substrate. The second aerosol-forming substrate can be a cigarette oil 202. The first heating component 10 and the second heating component 20 are fluidically connected, so that the second aerosol generated in the second heating component 20 can enter the first heating component 10 and mix with the first aerosol generated in the first heating component 10 before being output.

It is easy to understand that, since the second aerosol has a relatively high temperature, when the second aerosol passes through the aerosol generating product 201, it can also heat and bake the aerosol generating product 201, thereby providing the user with a better taste experience.

As can be understood in conjunction with FIG. 3 , the aerosol generating device 100 defines a heating chamber 111, and the heating chamber 111 is used to accommodate at least part of the aerosol generating product 201. The heating chamber 111 can be defined by a shell member of the aerosol generating device 100. The second heating component 20 is in fluid communication with the heating chamber 111. Since the second heating component 20 is in fluid communication with the heating chamber 111, the second aerosol can enter the heating chamber 111; accordingly, when the aerosol generating product 201 is placed in the heating chamber 111, the second aerosol can enter the interior of the aerosol generating product 201 as the user inhales.

The first heating component 10 may be a contact heating component, at least a local area of which is in contact with the aerosol generating article 201. In some embodiments, the first heating component 10 may include a coil for generating a changing magnetic field and a susceptor for inducing a changing magnetic field to generate an eddy current. The coil is disposed on the outer wall of the heating chamber 111, and the susceptor is disposed inside the heating chamber 111, and at least a portion of the coil may be inserted into the aerosol generating article 201 to heat the aerosol generating article 201 from the center. Of course, the susceptor may also be coated outside the aerosol generating article 201 to heat the aerosol generating article 201 from the circumference.

In some embodiments, the first heating component 10 may include a metal heating net, which may be coated on the outer wall of the heating chamber 111, and transfer heat from the circumference to the inside of the heating chamber 111 by resistive heating to heat the aerosol generating article 201. In some embodiments, the first heating component 10 may include a heating needle or a heating sheet, which is inserted into the aerosol generating article 201, and heats the aerosol generating article 201 from the center by resistive heating. In some embodiments, the first heating component 10 may also include a heating plate, which is located at the lower end of the aerosol generating article 201 but does not extend into the aerosol generating article 201.

The first heating component 10 may also be a non-contact heating component, such as infrared heating. The first heating component 10 includes an infrared radiator (not shown), which generates infrared rays for radiative heating of the aerosol generating article 201, and the aerosol generating article 201 may be heated from the center or the circumference.

In some embodiments, the first heating component 10 may include a heating substrate 11, an infrared electrothermal coating (not shown), a first electrode (not shown) and a second electrode (not shown). The heating substrate 11 may be hollow, and a heating chamber 111 for accommodating the aerosol generating product 201 is formed inside. The infrared electrothermal coating is coated on the outside of the heating substrate 11. The first electrode is arranged on the outside of the heating substrate 11 and is in contact with the infrared electrothermal coating, and the second electrode is arranged on the outside of the heating substrate 11 and is in contact with the infrared electrothermal coating, and at least a portion of the infrared electrothermal coating is located between the first electrode and the second electrode. The first electrode and the second electrode are used to be electrically connected to the battery core 40 so that at least a portion of the infrared electrothermal coating receives the heat generated by the electric power, thereby generating infrared rays for radiative heating of the aerosol generating product 201.

The second heating assembly 20 includes a liquid storage shell 21 and a liquid guide element 22. The liquid storage shell 21 defines a liquid storage chamber 211 inside, which is used to store a second aerosol-forming matrix, such as tobacco oil 202. The liquid guide element 22 is in fluid communication with the liquid storage chamber 211, and is used to absorb tobacco oil 202 from the liquid storage chamber 211, and transport the tobacco oil 202 to the heating element 23. The liquid guide element 22 can be made of a material with capillary channels or pores, such as fiber cotton, porous ceramic body, glass fiber rope, porous glass ceramic, porous glass and other hard or rigid capillary structures. The heating element 23 is used to heat at least part of the tobacco oil 202 absorbed by the liquid guide element 22 when powered on to generate an aerosol. After the aerosol escapes, it is released into the atomization chamber 23. The atomization chamber 23 is in fluid communication with the heating chamber 111, and the aerosol generated by the tobacco oil 202 can flow into the heating chamber 111 and enter the aerosol generating product 201 in the heating chamber 111.

Furthermore, the housing 30 is provided with an air inlet 31 for external air to enter the aerosol generating device 100. The air inlet 31 is in fluid communication with the atomizing chamber 23, and further in fluid communication with the heating chamber 111, forming an airflow path of the aerosol generating device 100, as shown by the arrow route R1 in FIG3 . Through this airflow path, the second aerosol in the atomizing chamber 23 can be carried to the heating chamber 111, and then the second aerosol enters the aerosol generating product 201, and mixes with the first aerosol generated by the aerosol generating product 201 being heated and volatilized. The user can inhale the mixed aerosol through the aerosol generating product 201, and the mixed aerosol has a richer taste than a single aerosol, and the inhalation taste will be better. In other examples, it is also feasible that the second aerosol can be directly mixed with the first aerosol generated by the heated volatilization of the aerosol generating product 201 without passing through the heating chamber 111, and then be inhaled by the user; for example, the first aerosol is independently output to the mixing chamber, and the second aerosol is independently output to the mixing chamber, thereby mixing with the first aerosol in the mixing chamber.

Further, the aerosol generating device 100 further includes a puff detector 50 and a circuit board 60. The circuit board 60 is provided with a controller and a switch tube, such as an MCU (single chip microcomputer or micro control unit). The switch tube guides the current between the battery 40 and the heating element 23. The MCU can output a PWM signal of a certain frequency and duty cycle to the switch tube, thereby controlling the power provided by the battery 40 to the heating element 23. The puff detector 50 and the battery 40 are both electrically connected to the circuit board 60. The battery 40 is a rechargeable battery, such as any one of a lead-acid battery, a nickel-cadmium battery, a nickel-iron battery, a nickel-hydrogen battery, a lithium-ion battery, etc. The puff detector 50 is used to detect the puff of the aerosol generating device 100 to output a puff signal. Specifically, the puff detector 50 can be an airflow sensor, which is fluidically connected to the air inlet 31. The airflow sensor senses the air pressure change of the aerosol generating device 100 and generates a puff signal according to the air pressure change, and then sends the puff signal to the controller of the circuit board 60. It is understandable that detecting whether the aerosol generating device 100 is inhaled is not limited to the above-mentioned situation; in other examples, it can also be detected and judged by other sensors, such as temperature sensors, pressure sensors, etc.; or by parameters detected by the circuit, such as voltage, current, power, etc. to detect and judge whether the aerosol generating device 100 is inhaled.

When the user inserts the aerosol generating product 201 into the heating chamber 111 in the first heating component 10 and inhales on the aerosol generating product 201, external air enters the aerosol generating device 100 under the action of the suction force, part of which flows to the heating chamber 111 through the airflow path R1, and the other part flows to the airflow sensor. The airflow sensor senses the negative pressure generated inside the aerosol generating device, and then generates a sensing signal and sends the sensing signal to the controller of the circuit board 60. The controller determines that the user is inhaling and needs to use the aerosol generating device 100, and the controller can control the battery cell 40 to provide the power required for heating to the first heating component 10 and the second heating component 20.

Furthermore, the aerosol generating device 100 further includes a bracket 80. The bracket 80 defines a receiving cavity (not shown), and the second heating component 20 is fixed in the receiving cavity to fix the second heating component 20.

Based on the above aerosol generating device 100, in one example, the controller is configured to control the first heating component 10 to start heating and enter a temperature rising stage when a power-on signal is detected.

The heating stage may be the time period t0 to t1 shown in FIG. 4 . During the heating stage, the temperature of the first heating component 10 rises from the initial temperature T0 to the target temperature T1. The initial temperature T0 may be the ambient temperature or may be greater than the ambient temperature. The target temperature T1 is between 150°C and 300°C, and may specifically be 220°C, 250°C, and the like. Generally, during the heating stage, the controller controls the power provided by the battery cell 40 to the first heating component 10 to be the maximum power, so that the temperature of the first heating component 10 is quickly raised to the target temperature T1, thereby shortening the user's waiting time for inhalation. The power-on signal may be a key signal from operating the aerosol generating device 100, or may be other indication signals.

After the heating stage is finished, the controller controls the first heating assembly 10 to enter the heat preservation stage.

The heat preservation stage is the time period t1 to t2 shown in Figure 4. In the heat preservation stage, the controller controls the power provided by the battery cell 40 to the first heating component 10 (the power corresponding to the heat preservation stage is less than the power corresponding to the heating stage) and controls the first heating component 10 to maintain the target temperature T1 for a period of time, such as 7 to 15 seconds, to provide sufficient energy to the aerosol generating article 201 and generate the first aerosol.

At time t2 or the end of the insulation stage, the controller outputs a prompt signal for the inhalable aerosol. Specifically, a prompt operation can be performed according to the prompt signal of the inhalable aerosol output by the controller through a prompt device (not shown in the figure) connected to the controller. For example: the prompt device is a vibration motor, and the vibration motor vibrates to remind the user that the aerosol can be inhaled according to the prompt signal of the inhalable aerosol output by the controller (including a start signal for controlling the operation of the vibration motor); the prompt device is an LED light, and the LED light is always on or flashing according to the prompt signal of the inhalable aerosol output by the controller to remind the user to inhale the inhalable aerosol.

It should be noted that the above-mentioned heating stage and heat preservation stage can be collectively referred to as the preheating stage, and the duration of the preheating stage is generally between 15 and 30 seconds. In the heating stage and the heat preservation stage, the second heating component 20 does not start heating. In other examples, it is also feasible to have no above-mentioned heat preservation stage.

After the heat preservation stage is finished, the controller controls the first heating assembly 10 to enter the suction stage.

The suction stage is the time period t2 to t3 shown in Fig. 4 , and the value of the time period t2 to t3 may be 180 seconds or the duration of 15 puffs. In the suction stage, the controller turns on the detection of the suction detector 50 .

In one example, if the puff signal output by the puff detector 50 is not obtained, the controller controls the power provided by the battery cell 40 to the first heating component 10 (the power corresponding to the puff stage is less than the power corresponding to the heat preservation stage) so that the first heating component 10 is maintained at a preset temperature T2, and the preset temperature T2 is less than the target temperature T1. In a specific implementation, the power provided by the battery cell 40 to the first heating component 10 by the controller is usually a fixed power. For example, when the temperature of the first heating component 10 is relatively low (less than the preset temperature T2), the controller controls the power provided by the battery cell 40 to the first heating component 10 to be a first power, so that the temperature of the first heating component 10 gradually rises; when the temperature of the first heating component 10 is relatively high (greater than the preset temperature T2), the controller controls the power provided by the battery cell 40 to the first heating component 10 to be a second power less than the first power, so that the temperature of the first heating component 10 gradually decreases, so that the temperature of the first heating component 10 fluctuates around the preset temperature T2.

If the puff signal output by the puff detector 50 is obtained, the controller controls the first heating component 10 to stop heating and controls the second heating component 20 to start heating. Since the second heating component 20 can quickly atomize the second aerosol to form a matrix and generate a second aerosol, the user can inhale the mixed aerosol. When the controller obtains the puff signal output by the puff detector 50, the timer (which can be an internal or external timer) is started for timing. If the timing time reaches the preset time, the second heating component 20 is controlled to stop heating and the first heating component 10 is controlled to start heating again. Generally, the preset time is less than the duration of a puff, for example, between 1 and 2 seconds, and specifically can be 1.5 seconds. It can be understood that the preset time can also be slightly longer than the duration of a puff or the same as the duration of a puff; in this way, during a puff, the first heating component 10 stops heating and the second heating component 20 remains in a heating state; after a puff ends, the first heating component 10 starts heating and the second heating component 20 stops heating.

When the controller controls the first heating component 10 to stop heating and controls the second heating component 20 to start heating, the working voltage of the controller will not be pulled too low, thereby triggering a protection interruption and causing the device to fail to work properly. This can be seen from the curve graph shown in FIG5 , as shown in the figure, curve A in the figure is a curve graph of the relationship between voltage and time when the controller controls the first heating component 10 to stop heating and controls the second heating component 20 to start heating, and curve B in the figure is a curve graph of the relationship between voltage and time when the controller controls the first heating component 10 and the second heating component 20 to start heating at the same time (both are when the suction signal output by the suction detector 50 is obtained).

In one example, the controller is configured to obtain the voltage of the battery cell; if the inhalation signal is obtained and the voltage of the battery cell is lower than a preset threshold, the first heating component is controlled to stop heating and the second heating component is controlled to start heating the second aerosol-forming substrate.

In this example, if the cell voltage is high, for example, the cell voltage is full voltage when the battery is just charged, even if the first heating component 10 and the second heating component 20 start heating at the same time, the operating voltage of the controller will not be pulled down below the load voltage protection point. Therefore, when the cell voltage is reduced, for example, when it is reduced to 3.6V or 3.5V, the first heating component 10 and the second heating component 20 can be controlled to start heating alternately.

In one example, when the controller controls the first heating component 10 to stop heating and controls the second heating component 20 to start heating, the controller controls the battery 40 to provide constant power to the second heating component 20. As can be seen from curve A in FIG5 , the operating voltage is relatively stable and will not fluctuate due to the heating of the first heating component 10. Therefore, the consistency of the second heating component 20 from puff to puff can be ensured, that is, the consistency of the smoking taste is ensured.

In a specific implementation, the controller can control the battery cell 40 to provide constant power to the second heating component 20 according to the duty cycle of the switch tube determined in advance or the duty cycle of the switch tube calculated in real time. For example, when controlling the second heating component 20 to start heating, the load voltage for turning on the second heating component 20 is determined, and the duty cycle of the PWM signal output to the switch tube is calculated according to the resistance value (known) of the heating element 23 and the preset output power, so as to control the battery cell 40 to provide constant power to the second heating component 20. Assuming that the load voltage for turning on the second heating component 20 is 3.7V, the resistance value of the heating element 23 is 0.5Ω, and the preset output power is 3W, the duty cycle of the PWM signal output to the switch tube is calculated as:

The above duty cycle can also be calculated when a power-on signal is detected. When the second heating component 20 is subsequently controlled to start heating, the switch tube is directly controlled by the calculated duty cycle.

In one example, during the suction stage, i.e., the time period t2 to t3 shown in FIG. 4 , the method of maintaining the first heating component 10 at the preset temperature T2 may be different from the aforementioned control of the power provided by the battery cell 40 to the first heating component 10. For example, the controller controls the battery cell 40 to provide a fixed energy to the first heating component 10, so that the first heating component 10 is maintained at the preset temperature T2.

Specifically, it is assumed that the fluctuation of the first heating component 10 above and below the preset temperature T2 is an energy supply cycle, and the energy supply cycle includes an energy supply duration stage and a natural cooling time stage (the unit natural cooling time refers to the time required for the temperature of the first heating component 10 to drop by one degree Celsius after the product design is completed; the natural cooling time can be the acceptable temperature drop range of the first heating component 10 determined according to the needs of the product design, thereby determining the time to stop supplying energy, and the natural cooling time can be several times the unit natural cooling time). During the energy supply process, the controller monitors the energy supplied by the battery cell 40 to the first heating component 10. If the energy supplied by the battery cell 40 to the first heating component 10 reaches the set energy, the controller controls the battery cell 40 to stop the energy supply, otherwise it continues to supply energy. Due to the lack of energy supply, the temperature of the first heating component 10 begins to drop, and the rate of drop is determined by the temperature drop capability of the first heating component 10; if the aerosol generating device 100 is inhaled during this time period, the drop rate will be relatively faster.

In this example, by controlling the first heating component 10 and the second heating component 20 to start heating alternately, the problem of inconsistent puffing taste caused by inconsistent power provided to the second heating component 20 during the previous and subsequent puffs can also be avoided. For example, if the first heating component 10 is always started to heat, during the energy supply process, the period when the controller controls the battery cell 40 to provide energy to the first heating component 10 and the period when the controller controls the battery cell 40 to stop supplying energy are different in their corresponding loads. When the duty cycle of the switch tube is calculated according to the above method, the problem of inconsistent power of the first heating component 10 in the two periods will be caused.

In one example, when the timing time reaches a preset time, the controller controls the second heating component 20 to stop heating and controls the first heating component 10 to start heating again, and the controller detects whether a puff signal is obtained again, that is, determines whether the user has puffed again. If the controller obtains a puff signal again, the aforementioned control steps are repeated until the puff stops or a shutdown signal is obtained.
