The aerosol generating device in the present application is a heat-not-burn device. During the use of the aerosol generating device, the heating element that heats the aerosol-forming substrate is often prone to various aerosol-forming substrate residues attached to the surface, thereby reducing the heating effect of the heating element.

The cleaning method of an embodiment of the present application includes detecting whether the aerosol-forming substrate is located in the aerosol generating device when the aerosol generating device meets the triggering conditions for cleaning; if so, entering a cleaning step, the cleaning step includes controlling the heating element to be heated to a cleaning temperature so that the residues of the aerosol-forming substrate attached to the heating element are detached from the heating element.

The cleaning device of the embodiment of the present application includes a detection module and a first control module. The detection module is used to detect whether the aerosol-forming substrate is located in the aerosol generating device when the aerosol generating device meets the triggering condition for cleaning; the first control module is used to enter a cleaning step when the aerosol-forming substrate is located in the aerosol generating device, and the cleaning step includes controlling the heating element to be heated to a cleaning temperature so that the residues of the aerosol-forming substrate attached to the heating element are detached from the heating element.

The aerosol generating device of an embodiment of the present application includes a processor, which is used to detect whether the aerosol-forming substrate is located in the aerosol generating device when the aerosol generating device meets the trigger condition for cleaning; if so, entering a cleaning step, the cleaning step includes controlling the heating element to be heated to a cleaning temperature so that the residue of the aerosol-forming substrate attached to the heating element is detached from the heating element.

Next, a heating element is controlled to heat the aerosol generating device to a cleaning temperature so that the residue of the aerosol-forming substrate attached to the heating element is separated from the heating element, thereby improving the heating effect of the heating element.

In addition, during the cleaning process, the aerosol-forming matrix remaining on the heating element can be vaporized at high temperature and adsorbed on the aerosol-forming matrix, thereby reducing gas odors and peculiar smells generated during the cleaning process.

DETAILED DESCRIPTION

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are optional and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

Referring to FIG. 1 and FIG. 2 , an embodiment of the present application provides a cleaning method for cleaning a heating element 30 of an aerosol generating device 100 . The cleaning method comprises:

Step 011: when the aerosol generating device 100 meets the triggering condition for cleaning, detecting whether the aerosol-forming substrate 200 is located in the aerosol generating device 100;

Among them, the aerosol-forming substrate 200 can be a substrate capable of releasing volatile compounds capable of forming an aerosol. Such volatile compounds can be released by heating the aerosol-forming substrate 200. The aerosol-forming substrate 200 can be adsorbed, covered, infused or loaded onto a carrier or support, for example, the aerosol-forming substrate 200 can include tobacco, and can be a tobacco-containing material containing volatile tobacco flavor compounds released from the aerosol-forming substrate when heated.

The aerosol-generating device 100 is a device that generates aerosol by heating rather than burning an aerosol-forming substrate 200, and the device generally comprises a heating element 30 and a receiving space for receiving the aerosol-forming substrate 200, so that the aerosol-forming substrate 200 is located in the receiving space. The heating element 30 may be arranged around the aerosol-forming substrate 200, or the heating element may be wrapped by the aerosol-forming substrate 200.

The triggering condition for cleaning can be automatic or manual. The automatic triggering can be a timed triggering, and the manual triggering can be triggered by a user through manual operation.

Specifically, the cleaning method is used to clean the heating element 30 of the aerosol generating device 100, and the heating element 30 can be conveniently formed in the shape of a needle, pin, rod or blade that can be inserted into a smoking article so as to contact the aerosol-forming substrate 200. The aerosol generating device 100 may include more than one heating element 30. When the aerosol generating device 100 meets the triggering condition for cleaning the heating element 30, the cigarette detection unit 40 used to detect the aerosol-forming substrate 200 in the aerosol generating device 100 needs to detect whether the aerosol-forming substrate 200 is located in the aerosol generating device 100. In the case where the aerosol-forming substrate 200 is located in the aerosol generating device 100, the aerosol-forming substrate 200 wraps the heating element 30; or, in the case where the aerosol-forming substrate 200 is located in the aerosol generating device 100, the aerosol-forming substrate 200 is located in the heating space surrounded by the heating element 30.

Step 012: When the aerosol-forming substrate 200 is located in the aerosol-generating device 100 , a cleaning step is entered, which includes controlling the heating element 30 to heat to a cleaning temperature so that the residue of the aerosol-forming substrate 200 attached to the heating element 30 is detached from the heating element 30 .

Among other things, the cleaning temperature may be a temperature high enough to thermally release organic compounds (i.e., residues of the aerosol-forming substrate 200) in contact with the heating element 30. The organic compound may be any particle or compound that adheres to or deposits on the surface of the heating element 30 during contact between the heating element 30 and the substrate. The cleaning temperature may be raised by any suitable method, for example, the temperature may be raised by conduction caused by contact with another heat source, the temperature may be raised by induction heating caused by a fluctuating electromagnetic field, or the temperature may be raised by resistive heating caused by passing an electric current through a wire or resistive track.

Specifically, when the cigarette detection unit 40 detects that the aerosol-forming matrix 200 is located in the aerosol generating device 100, the aerosol generating device 100 can enter a cleaning step, which specifically includes controlling the heating element 30 to heat to a cleaning temperature (the cleaning temperature can be 500 degrees Celsius, 600 degrees Celsius, etc.), so that the residues of the aerosol-forming matrix 200 attached to the heating element 30 are separated from the heating element 30 after heating at the cleaning temperature.

In this way, when the aerosol generating device 100 meets the triggering condition for entering the cleaning step, firstly, it is detected whether the aerosol-forming substrate 200 is located in the aerosol generating device 100. If the aerosol-forming substrate 200 is located in the aerosol generating device 100, the aerosol generating device 100 can enter the cleaning step, and then the heating element 30 is controlled to heat the aerosol generating device 100 to the cleaning temperature, so that the residue of the aerosol-forming substrate 200 attached to the heating element 30 is separated from the heating element 30, thereby improving the heating effect of the heating element 30. In addition, compared with separating the aerosol-forming substrate 200 from the aerosol generating device 100 and then heating the heating element 30 for cleaning, the present application always ensures that the aerosol-forming substrate is located in the aerosol generating device 100 during the cleaning process, so that the heating element 30 is always wrapped by the aerosol-forming substrate 200 during the cleaning process, thereby achieving the effects of heat insulation and heat absorption, and preventing the temperature of the aerosol generating device 100 from being too high.

Please refer to FIG. 1 and FIG. 3 , in some embodiments, the cleaning method further comprises:

Step 013: When the aerosol generating device 100 meets the triggering condition for cleaning, if the aerosol-forming substrate 200 is not in the aerosol generating device 100, the cleaning step will not be entered.

Specifically, when residues of the aerosol-forming substrate 200 are attached to the heating element 30 of the aerosol generating device 100 and the triggering condition for cleaning the heating element 30 is met, the cigarette detection unit 40 of the aerosol generating device 100 does not detect the presence of the aerosol-forming substrate 200 in the aerosol generating device 100, and the aerosol generating device 100 is controlled not to enter the cleaning step to clean the heating element 30.

In this way, by controlling the aerosol generating device 100 not to enter the cleaning step when the aerosol generating device 100 meets the triggering condition for cleaning and the aerosol forming matrix 200 is not in the aerosol generating device 100, the heating element 30 can be always wrapped by the aerosol forming matrix 200 during the cleaning process, thereby achieving the effects of heat insulation and heat absorption, preventing the aerosol generating device 100 from being overheated, and avoiding safety hazards.

In certain embodiments, the trigger condition includes the heating element 30 completing a preset number of heating cycles at the puff temperature, the puff temperature being less than the cleaning temperature.

The puffing temperature is a temperature high enough to emit volatile compounds from the aerosol-forming substrate 200 to form an aerosol; the puffing temperature is not too high to prevent scalding the user, and in order to clean the residue of the aerosol-forming substrate 200 during puffing, the heating element 30 is generally required to be heated to a cleaning temperature that is higher than the puffing temperature.

Among them, the completion of the heating cycle can be determined when the heating element 30 is heated at the puffing temperature (the puffing temperature can be 300 degrees Celsius, 400 degrees Celsius, etc.) for a first predetermined time (the first predetermined time can be 3 minutes, 6 minutes, etc.), and the heating element 30 is determined to have completed the heating cycle; or, when the heating element 30 is heated at the puffing temperature, if no puffing is detected within a second predetermined time (the second predetermined time can be 3 minutes, 4 minutes, etc.) (such as by detecting whether the user puffs the aerosol-forming matrix 200 through the airflow sensor built into the aerosol generating device 100), it is determined that the heating element 30 has completed the heating cycle; or, when it is detected that the number of puffs reaches a predetermined number of times (the preset number of times can be 5 times, 10 times, etc.), it is determined that the heating element 30 has completed the heating cycle; or, when an instruction to stop heating is received (such as the user pressing the stop heating button of the aerosol generating device 100), it is determined that the heating element 30 has completed the heating cycle.

Specifically, by heating the heating element 30 of the aerosol generating device 100 to the puffing temperature, and the user of the aerosol generating device 100 completes a preset number of (such as 1 time, 2 times, 4 times, etc.) heating cycles at the puffing temperature, the aerosol generating device 100 can automatically trigger a cleaning step of cleaning the heating element 30.

After the user of the aerosol generating device 100 completes a preset number of heating cycles, that is, the user of the aerosol generating device 100 no longer inhales the aerosol, the aerosol generating device 100 enters the cleaning step, and the heating element 30 continues to heat at the inhalation temperature until the temperature reaches the cleaning temperature. Compared with the user of the aerosol generating device 100 waiting for the heating element 30 to cool down after completing inhalation and then continuing to heat the heating element 30 to the cleaning temperature, energy consumption can be saved.

In some embodiments, the trigger condition includes the heating element 30 completing a heating cycle at the suction temperature and receiving a start cleaning instruction, and the suction temperature is less than the cleaning temperature.

Specifically, the triggering condition for the aerosol generating device 100 to clean the heating element 30 may also be that the heating element 30 is heated to the puffing temperature, the heating cycle is completed at the puffing temperature, and the aerosol generating device 100 receives a start cleaning instruction to start cleaning the heating element 30, and the aerosol generating device 100 enters the cleaning step of cleaning the heating element 30. The completion of the heating cycle generally indicates that the user of the aerosol generating device no longer inhales. At this time, the start cleaning instruction is manually generated to control the aerosol generating device 100 to enter the cleaning step, which can prevent the user from starting to clean at a higher cleaning temperature during the puffing process and scalding the user.

In some embodiments, the start cleaning instruction is generated by:

Pressing the start button 50 of the aerosol generating device 100 a preset number of times within a preset time;

Specifically, the aerosol generating device 100 has a start cleaning instruction and a start button 50. The start cleaning instruction can be generated by pressing the start button 50 of the aerosol generating device 100 for a preset number of times (the preset number of times can be 2 times, 3 times, etc.) within a preset time (the preset time can be 3 seconds, 5 seconds, etc.). For example, by pressing the start button 50 of the aerosol generating device 100 three times in succession within 3 seconds, the start cleaning instruction of the aerosol generating device 100 is generated.

The cleaning aerosol generating device 100 further comprises a first cleaning button 51, and the start-cleaning instruction is generated by the following actions:

Press the first cleaning button 51;

Specifically, the aerosol generating device 100 may have a first cleaning button 51, and the start cleaning instruction of the aerosol generating device 100 may be generated by pressing the first cleaning button 51. For example, when the aerosol generating device 100 completes the heating cycle, the first cleaning button 51 on the aerosol generating device 100 is pressed to generate a start cleaning instruction for cleaning the heating element 30, and the start cleaning instruction controls the aerosol generating device 100 to enter the cleaning step.

The aerosol generating device 100 is in communication connection with the electronic device, and the electronic device includes a second cleaning button, and the cleaning start instruction is generated by the following actions:

Press the second cleaning button.

Specifically, the aerosol generating device 100 can be connected to an electronic device via Bluetooth. For example, the electronic device can be a smart phone, a computer, etc. The electronic device can include a second cleaning button. For example, the second cleaning button can be a button displayed by the software on the mobile phone display. The start cleaning instruction of the aerosol generating device 100 can be generated by pressing the second cleaning button on the electronic device. For example, when the aerosol generating device 100 meets the triggering conditions for cleaning, the second cleaning button displayed on the mobile phone display by the mobile phone software can be pressed to start the start cleaning instruction for cleaning the heating element 30. The start cleaning instruction controls the aerosol generating device 100 to enter the cleaning step.

In this way, the aerosol generating device 100 manually issues a start cleaning instruction to trigger the cleaning step, which is safer than automatically triggering the cleaning step.

Referring to FIG. 1 and FIG. 4 , in certain embodiments, the aerosol generating device 100 further includes a prompting element 60 . Before entering the cleaning step, the cleaning method further includes:

Step 014: Control the prompt element 60 to issue a first prompt message;

The aerosol generating device 100 further includes a prompt element 60 , which may be at least one of a prompt light, a vibrator and a speaker.

The first prompt information may be to inform the aerosol generating device 100 to start the cleaning step. For example, the first prompt information may be at least one of a prompt light flashing in a first preset color, a prompt light being always on in the first preset color, a vibrator vibrating, and a speaker emitting a first preset voice.

Specifically, after the aerosol generating device 100 receives the start cleaning instruction for cleaning the heating element 30, the aerosol generating device 100 starts to enter the cleaning step. Before the aerosol generating device 100 enters the cleaning step, the aerosol generating device 100 needs to control the prompt element 60 to issue a first prompt message. For example, before the aerosol generating device 100 controls the heating element 30 to heat to the cleaning temperature, the aerosol generating device 100 controls the indicator light to flash in a first preset color (such as red, green, blue, etc.); and/or before the aerosol generating device 100 controls the heating element 30 to heat to the cleaning temperature, the aerosol generating device 100 controls the vibrator to vibrate; and/or before the aerosol generating device 100 controls the heating element 30 to heat to the cleaning temperature, the speaker emits a first preset voice (such as a voice message of "cleaning is about to start" or three short ticking sounds).

During the cleaning of the heating element 30 at the cleaning temperature, the cleaning method further comprises:

Step 015: Control the prompt element 60 to issue a second prompt message;

Among them, the second prompt information can be to inform the aerosol generating device 100 that the heating element 30 is being cleaned. For example, the second prompt information can be at least one of a prompt light flashing in a second preset color, a prompt light being always on in the second preset color, a vibrator vibrating, and a speaker emitting a second preset voice.

Specifically, after the aerosol generating device 100 receives the start cleaning instruction for cleaning the heating element 30, the aerosol generating device 100 enters a cleaning step. During the process of cleaning the heating element 30 at the cleaning temperature, the cleaning method also includes the aerosol generating device 100 controlling the prompt element 60 to issue a second prompt message. For example, during the process of cleaning the heating element 30 at the cleaning temperature, the aerosol generating device 100 controls the prompt light to flash according to a second preset color (such as red, green, blue, etc.); and/or during the process of cleaning the heating element 30 at the cleaning temperature, the prompt light of the aerosol generating device 100 is always on according to the second preset color; and/or during the process of cleaning the heating element 30 at the cleaning temperature, the aerosol generating device 100 controls the vibrator to vibrate; and/or during the process of cleaning the heating element 30 at the cleaning temperature, the aerosol generating device 100 controls the speaker to issue a second preset voice (such as a voice message of "cleaning in progress" or a continuous ticking sound).

After the heating element 30 is cleaned at the cleaning temperature, the cleaning method further comprises:

Step 016: Control the heating element 30 to stop heating and control the prompt element 60 to issue a third prompt message.

Among them, the third prompt information can be to inform the aerosol generating device 100 that the cleaning step of the heating element 30 has been completed. For example, the third prompt information can be at least one of the prompt light turning off, the prompt light flashing in a third preset color, the prompt light being always on in the third preset color, the oscillator vibrating, and the speaker emitting a third preset voice.

Specifically, after the aerosol generating device 100 receives the start cleaning instruction for cleaning the heating element 30, the aerosol generating device 100 enters the cleaning step. After the heating element 30 completes cleaning at the cleaning temperature, the cleaning method also includes controlling the heating element 30 to stop heating and controlling the prompt element 60 to send a third prompt message. For example, after the aerosol generating device 100 completes cleaning at the cleaning temperature, the aerosol generating device 100 controls the prompt light to turn off; and/or the aerosol generating device 100 completes cleaning at the cleaning temperature after the heating element 30 completes cleaning at the cleaning temperature. and/or after the aerosol generating device 100 completes cleaning at the cleaning temperature of the heating element 30, the prompt light flashes in a third preset color (such as red, green, blue, etc.); and/or after the aerosol generating device 100 completes cleaning at the cleaning temperature of the heating element 30, the prompt light is always on in the third preset color; and/or after the aerosol generating device 100 completes cleaning at the cleaning temperature of the heating element 30, the aerosol generating device 100 controls the vibrator to vibrate; and/or after the aerosol generating device 100 completes cleaning at the cleaning temperature of the heating element 30, the speaker emits a third preset voice (such as "Cleaning completed" or three short ticks and then stops).

In this way, the aerosol generating device 100 can inform that the aerosol generating device 100 is in the process of the cleaning step by controlling the prompt element 60 to send a first prompt message before controlling the heating element 30 to heat to the cleaning temperature, controlling the prompt element 60 to send a second prompt message during the process of the heating element 30 cleaning at the cleaning temperature, and controlling the heating element 30 to stop heating and controlling the prompt element 60 to send a third prompt message after the heating element 30 completes cleaning at the cleaning temperature.

Referring to FIG. 1 and FIG. 5 , in certain embodiments, the aerosol generating device 100 further includes a prompting element 60 . Before entering the cleaning step, the cleaning method further includes:

Step 017: Control the heating element 30 to stop heating and control the prompt element 60 to send out a first prompt message.

Specifically, the aerosol generating device 100 also includes a prompt element 60. After the aerosol generating device 100 receives the start-cleaning instruction for cleaning the heating element 30, before the aerosol generating device 100 enters the cleaning step, the aerosol generating device 100 needs to control the heating element 30 to stop heating, and then the aerosol generating device 100 controls the prompt element 60 to send a first prompt message. For example, after the aerosol generating device 100 receives the start-cleaning instruction for cleaning the heating element 30, the aerosol generating device 100 controls the heating element 30 to stop heating, and the aerosol generating device 100 controls the indicator light to flash according to a first preset color (such as red, green, blue, etc.); and/or before the aerosol generating device 100 controls the heating element 30 to heat to the cleaning temperature, the aerosol generating device 100 controls the vibrator to vibrate; and/or before the aerosol generating device 100 controls the heating element 30 to heat to the cleaning temperature, the speaker sends a first preset voice (such as a voice message of "cleaning is about to start" or three short ticking sounds).

In this way, before the aerosol generating device 100 controls the heating element 30 to heat to the cleaning temperature, the aerosol generating device 100 controls the heating element 30 to stop heating and controls the prompt element 60 to send a first prompt message, which can prompt the aerosol generating device 100 to enter the cleaning step, thereby avoiding the action of inhaling aerosol after entering the cleaning step, thereby causing burns to the user.

Referring to FIG. 1 and FIG. 6 , in some embodiments, the aerosol generating device 100 further includes a motion detection unit 70 and a prompt element 60 , and the cleaning method further includes:

Step 018: When the motion detection unit 70 detects that the motion acceleration of the aerosol generating device 100 is greater than a preset value, the control prompt element 60 sends an alarm message and controls the heating element 30 to stop heating.

The motion detection unit 70 may be a gyroscope, an accelerometer, etc., which may be used to detect whether the aerosol generating device 100 is moved, and the motion acceleration of the movement.

Specifically, the aerosol generating device 100 includes a motion detection unit 70 and a prompt element 60. When the motion detection unit 70 detects that the motion acceleration of the aerosol generating device 100 during the cleaning process is greater than a preset value, the prompt element 60 is controlled to issue an alarm message and control the heating element 30 to stop heating. For example, a spatial rectangular coordinate system (including three mutually perpendicular axes (such as the x-axis, the y-axis, and the z-axis)) is set with the center of the aerosol generating device 100 as the origin. The motion detection unit 70 is used to detect the three-axis acceleration of the aerosol generating device 100 in the spatial rectangular coordinate system. When the gyroscope It is detected that the aerosol generating device 100 generates accelerations in the x-axis, y-axis and z-axis respectively, and the movement acceleration of the aerosol generating device 100 is obtained by calculation, and then the calculated movement acceleration of the aerosol generating device 100 is compared with a preset value (the preset value may be 5 meters per square second, 10 meters per square second, etc.). When the calculated movement acceleration of the aerosol generating device 100 is greater than the preset value, the prompt element 60 may be controlled to issue an alarm message (such as a prompt light flashing red, issuing an alarm message of "Warning, cleaning in progress", issuing a rapid ticking sound, etc.) and the heating element 30 may be controlled to stop heating.

Step 019: When the motion detection unit 70 detects that the motion trajectory of the aerosol generating device 100 meets a preset condition, the control prompt element 60 sends an alarm message and controls the heating element 30 to stop heating.

Specifically, during the cleaning step of the aerosol generating device 100, when the motion detection unit 70 detects that the motion trajectory of the aerosol generating device 100 meets the preset conditions, the control prompt element 60 issues an alarm message and controls the heating element 30 to stop heating. For example, after the motion detection unit 70 detects the three-axis acceleration of the aerosol generating device 100 in the spatial rectangular coordinate system, the motion trajectory of the aerosol generating device 100 can be determined by the three-axis acceleration. When the motion trajectory meets the preset conditions (such as when the motion trajectory is the trajectory corresponding to lifting the aerosol generating device 100), the prompt element 60 can be controlled to issue an alarm message (such as the prompt light flashing red, issuing an alarm message of "Warning, cleaning in progress", issuing a rapid ticking sound, etc.) and the heating element 30 can be controlled to stop heating.

The motion detection unit 70 and the prompt element 60 included in the aerosol generating device 100 are used to detect the motion acceleration and motion trajectory of the aerosol generating device 100. When it is detected that the motion acceleration of the aerosol generating device 100 during the cleaning step is greater than a preset value or the motion trajectory meets the preset conditions, the prompt element 60 is controlled to issue an alarm message and the heating element 30 is controlled to stop heating. In this way, the user can be prompted during the cleaning process of the aerosol generating device 100 to prevent the user from inhaling during the cleaning process.

Please refer to Figure 7. In some embodiments, the aerosol generating device 100 also includes a cigarette detection unit 40. The cigarette detection unit 40 is disposed in a receiving cavity of the aerosol generating device 100 that receives the aerosol-forming matrix 200. The cigarette detection unit 40 is used to detect whether the aerosol-forming matrix 200 is located in the aerosol generating device 100.

The cigarette detection unit 40 may detect whether the aerosol-forming matrix 200 is located in the aerosol generating device 100 , and further may detect whether the aerosol matrix is in contact with the heating element 30 .

Specifically, the aerosol generating device 100 also includes a cigarette detection unit 40 (the cigarette detection unit 40 may be a laser detector, a capacitive position sensor, etc.). The cigarette detection unit 40 is disposed in a receiving cavity of the aerosol generating device 100 that receives the aerosol-forming substrate 200, and may be used to detect whether the aerosol-forming substrate 200 is located in the aerosol generating device 100. For example, the cigarette detection unit 40 may be a laser detector. When the aerosol-forming substrate 200 enters the aerosol generating device 100, the laser emitted by the laser detector located on the inner wall of the receiving cavity that receives the aerosol-forming substrate 200 is blocked by the aerosol-forming substrate 200, indicating that the aerosol-forming substrate 200 has reached a predetermined position; or the cigarette detection unit 40 may be a capacitive position sensor. When the aerosol-forming substrate 200 enters the aerosol generating device 100, the magnetic field formed by the corresponding capacitors on both sides of the capacitive position sensor located on the inner wall of the receiving cavity that receives the aerosol-forming substrate 200 changes, indicating that the aerosol-forming substrate 200 has reached a predetermined position.

In this way, by providing the cigarette detection unit 40 on the aerosol generating device 100 , it is possible to accurately detect whether the aerosol-forming substrate 200 is located in the aerosol generating device 100 .

Please refer to FIG6 .
