As shown in fig. 4-6, the aerosol-generating device 200 further comprises a heater 1 and a color detection means comprising a light source 201 and a color sensor 202.
The heater 1 is for heating at least a portion of an aerosol-generating article 100 received in a chamber of an aerosol-generating device 200 to generate an aerosol for inhalation.
The heater 1 may be a central heating mode (in which the heater is in direct contact with the aerosol-forming substrate through the periphery of the heater) or a peripheral heating mode (in which the cylindrical heater wraps the aerosol-forming substrate), or may be a heater that heats the aerosol-forming substrate through one or more of heat conduction, electromagnetic induction, chemical reaction, infrared action, resonance, photoelectric conversion, and photothermal conversion to generate aerosol for inhalation.
The following description will be given taking the heater 1 as an infrared heater as an example:
as shown in fig. 6, the heater 1 includes a substrate 11, an infrared electrothermal coating 12, and a conductive member 13.
The substrate 11 may be cylindrical, prismatic, or other cylindrical shape, and is preferably cylindrical. The base 11 is hollow inside and constitutes at least part of the chamber of the aerosol-generating device 200, and the base 631 at the upper end of the base 11 is provided with a through hole corresponding to the hollow into which the aerosol-generating article 100 is removable or insertable in sequence through the opening a.

As shown in fig. 4-5, the light source 201 and the colour sensor 202 are provided in a through hole of the base 631, the colour sensor 202 being provided at a position corresponding to the label C1 of the aerosol-generating article 100 when the aerosol-generating article 100 is inserted into the chamber of the aerosol-generating device 200 in position. The light source 201 is configured to emit light into the chamber of the aerosol-generating device 200, i.e. into the through-hole of the base 631; a color sensor 202 configured to detect a reflection of the light to generate a color signal.
In this example, the light source 201 may be an LED lamp. The color sensor 202 may include a color filter and a photoelectric converter, which detect a color in the reflection of the light by a color filter and a photodetector and generate a corresponding color signal. Photodetectors include, but are not limited to, photodiodes, photoresistors, phototransistors, and the like. Note that the configuration of the color sensor 202 is not limited to this case. It is also possible that the light source 201 and the color sensor 202 may be provided separately or integrated together.
The aerosol-generating device 200 further comprises a controller which may control the overall operation of the aerosol-generating device 200. In detail, the controller controls not only the operation of the battery 7 and the heater 1, but also the operation of other elements in the aerosol-generating device 200. Further, the controller may determine whether the aerosol-generating device 200 is operable by checking the status of elements of the aerosol-generating device 200. In this example, the controller acquires the color signal generated by the color sensor 202, and generates a control signal to control the operation of the heater 1 according to the color signal.
The controller includes at least one processor. The processor may comprise an array of logic gates, or may comprise a combination of a general purpose microprocessor and memory storing programs executable in the microprocessor. Further, one skilled in the art will appreciate that the controller may comprise another type of hardware.
In an example, the aerosol-generating device 200 further comprises:
the input module is used for receiving an opening instruction input by a user to generate an opening signal;
the microcontroller is further configured to receive the turn-on signal, and control the light source 201 and the color sensor 202 to turn on according to the turn-on signal.
In this example, the input module may be the key 4 shown in fig. 3, but is not limited to this case.
As will be understood in conjunction with fig. 1 to 6, in an example, the controller is further configured to generate an article insertion in-place signal when the second color signal and the first color signal generated by the color sensor 202 are sequentially acquired within a first preset time; and controlling the heater 1 to start heating according to the product insertion in-place signal.
In particular, when the aerosol-generating article 100 is inserted into the hollow portion of the substrate 11 sequentially through the opening a, the through-hole of the base 631, the light emitted by the light source 201 will impinge on the aerosol-generating article 100, and the colour sensor 202 will detect the colour of the outer surface of the tobacco segment 102 and the colour of the label C1 in sequence and generate corresponding second and first colour signals. Upon acquiring the second color signal and the first color signal, the controller may determine that the aerosol-generating article 100 is inserted into the chamber of the aerosol-generating device 200 in place, thereby generating an article insertion in-place signal. The heater 1 is then controlled to automatically activate heating by the product insertion in-place signal.
Further, the controller is further configured to:
determining from the first colour signal the identity of the aerosol-generating article 100 received in the chamber; determining, from the type of aerosol-generating article 100, its corresponding temperature profile; controlling power supplied to the heater 1 according to the temperature configuration information.
In particular, the colour of the label C1 may be indicative of one taste of different aerosol-generating articles 100, for example: red for mint, blue for coffee, mango, etc. Upon acquisition of the first color signal by the color sensor 202, a corresponding heating profile, i.e., temperature configuration information, may be selected among the previously stored heating profiles. And then controls the heater 1 to heat according to the heating curve, so that the user can obtain the best taste.
Further, the controller is further configured to:
under the condition that a second color signal and a third color signal generated by the color sensor 202 are sequentially acquired within a second preset time, a product pulling-out signal is generated; and controlling the heater 1 to stop heating according to the product pulling-out signal.
In particular, when the heater 1 is controlled to automatically initiate heating, if a user pulls the aerosol-generating article 100 out of the chamber of the aerosol-generating device 200, the colour sensor 202 will detect the colour of the outer surface of the tobacco segment 102 and the colour of the inner wall of the chamber in sequence and generate corresponding second and third colour signals. The controller, upon acquiring the second and third colour signals in sequence, may determine that the aerosol-generating article 100 is removed from the cavity of the aerosol-generating device 200, thereby generating an article pull-out signal and controlling the heater 1 to stop heating.
Further, the controller is further configured to:
generating a product no-insert-bit signal when only a second color signal generated by the color sensor 202 is acquired within a second preset time; and controlling the heater to stop heating and recording the heating time of the heater which is finished according to the product insertion-less-bit signal.
In particular, if the aerosol-generating article 100 is accidentally dialled resulting in a non-correct insertion of the aerosol-generating article 100 into the chamber of the aerosol-generating device 200 after controlling the heater 1 to automatically initiate heating, the colour sensor 202 may only detect the colour of the outer surface of the tobacco segment 102 and generate a corresponding second colour signal. When the second colour signal is obtained, the controller can determine that the aerosol-generating article 100 is not inserted in place and then generate an article not-inserted-in-place signal, control the heater 1 to stop heating and record the time for which the heater 1 has completed heating.
Further, the controller is further configured to:
after the heater 1 is controlled to stop heating, generating first prompt information;
the aerosol-generating device 200 further comprises:
a first prompting module for obtaining the first prompting information to prompt a user that an abnormality exists in a location of the aerosol-generating article 100.
In particular, after the heater 1 has been activated to heat, if the aerosol-generating article 100 is accidentally dialled, causing the heater 1 to cease heating, the user may be alerted by vibration, light or sound to the presence of an anomaly in the aerosol-generating article location 100, facilitating the user to reinsert the aerosol-generating article 100 into position in the chamber.
Further, the controller is further configured to:
under the condition that the second color signal and the first color signal generated by the color sensor 202 are sequentially acquired within a third preset time, a product reinsertion in-place signal is generated; calculating the remaining heating time of the heater according to the completed heating time of the heater; and controlling the heater 1 to heat according to the product reinsertion-in-place signal and the remaining heating time of the heater.
In particular, after the heater 1 has been activated to heat, if the aerosol-generating article 100 is accidentally dialled, the heater 1 is caused to cease heating. If the user reinserts the aerosol-generating article 100 into position in the chamber, heating of the aerosol-generating article 100 can continue without the user initiating heating, further simplifying operation of the aerosol-generating device 200 and improving user experience.
Further, the controller is further configured to:
when only the second color signal generated by the color sensor 202 is acquired within a first preset time or when the second color signal and the fourth color signal generated by the color sensor 202 are sequentially acquired within the first preset time, the heater 1 is controlled to be in an off state.
In particular, a situation in which only the second color signal generated by the color sensor 202 is acquired within a first predetermined time may be considered that the aerosol-generating article 100 is not inserted in place. At this time, the heater 1 is controlled to be in a disconnected state without controlling the heater 1 to start heating. Alternatively, when the second color signal and the fourth color signal generated by the color sensor 202 are acquired sequentially within a first predetermined time, it may be determined that an aerosol-generating article is inserted that does not match the aerosol-generating device 200. At this time, the heater 1 does not need to be controlled to start heating, namely, the heater 1 is controlled to be in a disconnected state. Wherein the fourth color is different from the color of label C1, and is different from the color of the outer surface of tobacco segment 102 and the color of the inner wall of the chamber.
The first preset time, the second preset time, and the third preset time may be empirical values, and are set when the aerosol-generating device 200 is shipped; or set by the user himself.
Further, the controller is further configured to:
generating second prompt information when only the second color signal generated by the color sensor 202 is acquired within a first preset time or when the second color signal and the fourth color signal generated by the color sensor 202 are sequentially acquired within the first preset time;
the aerosol-generating device 200 further comprises:
and the second prompt module is used for receiving the second prompt information and prompting the user that the abnormality exists.
Fig. 7 is a schematic flow chart of a control method of an aerosol-generating device according to an embodiment of the present disclosure. The method comprises the following steps:
step S11, a color signal generated by the color detection device is acquired.
And step S12, generating a control signal according to the color signal to control the operation of the heater.
An overall control process for the aerosol-generating device 200 is described below in connection with fig. 8:
step S21, inserting cigarettes;
step S22, detecting whether the cigarette is inserted;
specifically, when a cigarette is inserted, the color sensor 202 detects the color of the outer surface of the tobacco segment 102 and generates a corresponding second color signal, thereby determining that the cigarette is inserted.
Step S23, continuously inserting cigarettes;
step S25, detecting that the cigarette is inserted in place;
specifically, when a cigarette is inserted into the chamber, the color sensor 202 will sequentially detect the color of the outer surface of the tobacco segment 102 and the color of the label C1 and generate corresponding second and first color signals.
Step S26, when the cigarette is inserted into the chamber in place, the controller controls the heater to start heating;
step S261, step S27: the cigarette heating is finished, the cigarette is pulled out, and the heating is finished;
