Referring to fig. 1 to 4, an aerosol-generating device 100 includes a power source 1, a first heater 2, a second heater 3, a transfer channel 4, a third heater 5, and a controller (not shown), wherein the power source 1 is used for providing power, the first heater 2 is used for heating a first aerosol-forming substrate to generate a first aerosol, the second heater 3 is used for heating a second aerosol-forming substrate to generate a second aerosol, the transfer channel 4 is used for transferring the first aerosol to mix the first aerosol with the second aerosol and output, the third heater 5 is used for raising the temperature in the transfer channel 4 to clear condensate in the transfer channel 4, and the controller (not shown) is configured to control the power source 1 to provide power to at least one of the first heater 2, the second heater 3, and the third heater 5.

A controller configured to control the power supply 1 to supply power to the third heater 5 based on the acquired cleaning instruction, wherein the cleaning instruction includes at least one of: a power on signal, a power off signal, a timing or clocking signal, a key signal, an air pressure or air flow signal, a temperature signal, a heating period or a stop heating period of the first heater 2 and/or the second heater 3, a number of suction ports, a suction period, a number of first aerosol-forming substrates and/or the second aerosol-forming substrates.

In some embodiments, the clear instruction is a power-on signal. As an example, the aerosol-generating device 100 comprises a touch screen or keys for a user to input a start-up command and generate a start-up signal, and when the start-up signal is transmitted to the controller, the controller controls the power supply 1 to supply power to the third heater 5, so that the temperature inside the transmission channel 4 increases, thereby evaporating condensate. By cleaning the condensate in the transmission channel 4 during starting up, the transmission channel 4 is prevented from being blocked by the condensate, so that the aerosol generating device cannot be used, and the use experience of a user is improved.

In some embodiments, the cleanup instruction is a shutdown signal. As an example, the aerosol-generating device 100 comprises a touch screen or a key for a user to input a shutdown command and generate a shutdown signal, and when the shutdown signal is transmitted to the controller, the controller controls the power supply 1 to supply power to the third heater 5, thereby raising the temperature inside the transmission channel 4, so that condensate is evaporated.

It will be appreciated that the shutdown signal may also be generated after the first heater 2 and the second heater 3 have stopped heating for a period of time.

It will also be appreciated that there is a certain residual temperature in the transfer channel 4 during shutdown, and therefore the cleaning of the condensate is initiated during shutdown, which saves energy of the aerosol-generating device.

In some embodiments, in consideration of that condensate is generated during each use of the aerosol-generating device 100, as time passes, more condensate is accumulated inside the aerosol-generating device 100, and the transmission channel 4 is blocked due to accumulation of condensate, so that the user may not suck smoothly, and therefore, in order to avoid the above phenomenon, the cleaning instruction is a timing signal. As an example, the aerosol-generating device 100 further comprises a timer or timer (not shown) electrically connected to the controller, which controls the power supply 1 to supply power to the third heater 5 when the time of the timer or timer reaches a preset time, thereby causing the temperature inside the transmission channel 4 to rise, thereby evaporating the condensate.

It will be appreciated that a timer or timer may count the operating time of the first heater 2 and/or the second heater 3 and that when the operating time reaches a predetermined time the controller controls the power supply 1 to supply power to the third heater 5 to clear the condensate.

In other examples, a timer or timer is used to count the run time of the aerosol-generating device 100, thereby providing the aerosol-generating device 100 with an over-suction stop function. When the time of using the aerosol-generating device by the user reaches or exceeds the preset use time, the overdischarge stopping function of the aerosol-generating device 100 is triggered, and then a signal is transmitted to the controller, and the controller controls the power supply 1 to stop supplying power to the first power supply 1 and the second power supply 1.

In some embodiments, the clear instruction is a key signal. As an example, the aerosol-generating device 100 further comprises a key (not shown) electrically connected to the controller, the key being configured to allow a user to input a key command and generate a key signal, and when the key signal is transmitted to the controller, the controller controls the power supply 1 to supply power to the third heater 5, thereby increasing the temperature inside the transmission channel 4, and evaporating condensate. The purpose that the user independently controls and cleans the condensate in the using process is achieved, so that the user can clean the condensate at any time according to the self requirement.

In some embodiments, the purge instruction is an air pressure or air flow signal. As an example, the aerosol-generating device 100 further comprises a gas pressure sensor 7, the gas pressure sensor 7 being in fluid communication with the transmission channel 4, the gas pressure sensor 7 being electrically connected to a controller, the gas pressure sensor 7 being arranged to detect the gas pressure of the transmission channel 4, the controller controlling the power supply 1 to supply power to the third heater 5 in dependence on the gas pressure detected by the gas pressure sensor 7, thereby causing the temperature inside the transmission channel 4 to rise, thereby evaporating condensate. For example, the controller sets a preset air pressure, when the user sucks, the air pressure in the transmission channel 4 is reduced, at this time, the air pressure in the transmission channel 4 is smaller than the preset air pressure, and the controller controls the power supply 1 to stop supplying power to the third heater 5, so that the user is prevented from cleaning condensate in the sucking process; when the user does not use the aerosol-generating device 100, the internal air pressure of the transmission channel 4 returns to normal, and at this time, the internal air pressure of the transmission channel 4 is substantially consistent with the preset air pressure, and the controller controls the power supply 1 to supply power to the third heater 5, so as to achieve the purpose of cleaning the condensate when the user does not use the aerosol-generating device.

In some embodiments, the purge instruction is a temperature signal. As an example, the aerosol-generating device 100 further comprises a temperature sensor (not shown) electrically connected to the controller for detecting the temperature in the transmission channel 4, the controller controlling the power supply 1 to supply power to the third heater 5 in dependence on the temperature detected by the temperature sensor. For example, by setting the preset temperature, when the user uses the aerosol-generating device 100, if the temperature of the transmission channel 4 is lower than the preset temperature, condensate is easily formed in the transmission channel 4, and at this time, the controller may control the power supply 1 to supply power to the third heater 5, so as to achieve the purpose of cleaning the condensate. In particular the influence of the ambient temperature on the temperature inside the transmission channel 4, for example: the temperature in the transmission channel 4 is relatively low when the ambient temperature in winter snowy days is low, and condensate is easy to form in the transmission channel 4.

In some embodiments, the purge instruction is a number of suction ports. Illustratively, the aerosol-generating device 100 further comprises a counter (not shown) electrically connected to the controller, the counter being configured to count the number of openings drawn by the user, and the controller being configured to control the power source 1 to supply power to the third heater 5 for the purpose of cleaning the condensate based on the counted number of openings drawn by the counter. For example, when the number of openings sucked by the user is greater than the preset number of openings during use of the aerosol-generating device 100, the controller controls the power supply 1 to supply power to the third heater 5 for the purpose of cleaning the condensate.

In some embodiments, when the cleaning command is a heating period or a stop period of the first heater 2, a heating period or a stop period of the second heater 3, a pumping period, a number of first aerosol-forming substrates, a number of second aerosol-forming substrates, or the like, the cleaning command is a heating period or a stop period of the first heater 2, a heating period or a stop period of the second heater 3, a pumping period, a number of first aerosol-forming substrates, a number of second aerosol-forming substrates (for example, when the second aerosol-forming substrates is cigarettes, and when the number of cigarettes pumped reaches a preset number, the power supply 1 is controlled to supply power to the third heater 5 for the purpose of cleaning condensate), reference may be made to the above-mentioned other cleaning command embodiments, which are not repeated here.

In some embodiments, when the second aerosol-forming substrate is a solid aerosol-forming substrate, the controller is configured to control the power supply 1 to supply power to the second heater 3 to preheat the solid aerosol-forming substrate, and to control the power supply 1 to supply power to the third heater 5 when the solid aerosol-forming substrate is preheated. In this way, condensation of the inflowing aerosol in the transport channel 4 due to an excessively low temperature inside the transport channel can be avoided.

Further, a controller (not shown) is configured to detect the temperature in the transfer channel 4 when preheating the solid aerosol-forming substrate, and to control the power supply 1 to supply power to the third heater 5 based on the temperature in the transfer channel 4.

Furthermore, by adjusting the temperature in the transmission channel 4, the aerosol-generating device 100 may be made to achieve a regulation of the suction mouth feel. For example, the temperature sensor detects the temperature inside the transmission path 4, and the controller controls the power supply 1 to supply power to the third heater 5 based on the temperature of the transmission path 4, thereby adjusting the temperature inside the transmission path 4.
