Description

Technology Field

[0001] The embodiments of the present application relate to the field of smoking set technology, and in particular to an aerosol generating device, method, and system.

[0002] This application claims priority to a Chinese patent application filed with the Chinese Intellectual Property Office on August 11, 2020, with application number 202010801561.7 and titled “Aerosol generating device and method and system thereof,” all of which are incorporated herein by reference. Background Technology

[0003] For example, smoking products such as cigarettes and cigars generate smoke by burning tobacco during use. Attempts have already been made to provide substitutes for these tobacco-burning products through products that release compounds in a non-combustion state. An example of such a product is the so-called heated non-combustion product, which releases compounds by heating the tobacco rather than burning it.

[0004] Conventional smoking sets typically feature a single sensor in the cigarette insertion slot to simplify user operation, detecting whether a cigarette has been inserted and subsequently controlling the heater to initiate heating. However, this sensor cannot detect whether the cigarette is inserted in the correct position; by activating heating when the cigarette is not inserted correctly, it prevents the cigarette from heating effectively, thereby affecting the inhalation experience. A solution involves adding an additional sensor within the cigarette cavity to detect whether the cigarette is inserted in the correct position. However, adding this sensor increases the hardware cost of the smoking set and reduces product competitiveness. The problem to be solved

[0021] Unless otherwise defined, all technical and scientific terms used herein have the meanings commonly understood by those skilled in the art of this application. Terms used in the description of this application within this specification are intended to describe specific embodiments and are not intended to limit this application. As used herein, “and / or” includes any and all combinations of one or more related listed items.

[0022] FIG. 1 is a drawing of an aerosol generating device provided by an embodiment of the present application.

[0023] As illustrated in FIG. 1, the aerosol generating device comprises an aerosol generating product (100) and an aerosol generating device (200). The aerosol generating device (200) has a cavity for receiving or removing the aerosol generating product (100), the aerosol generating product (100) is inserted or pulled out from the cavity through an opening (A) on the aerosol generating device (200), and the aerosol generating device (200) is intended to generate an aerosol for inhalation by heating at least a portion of the aerosol generating product (100) inserted into the cavity.

[0024] FIG. 2 is a drawing of an aerosol-generating product provided by an embodiment of the present application.

[0025] As shown in FIG. 2, the aerosol generating product (100) includes a filter section (101) and a tobacco section (102).

[0026] The tobacco section (102) includes an aerosol generating substrate. The aerosol generating substrate is a substrate capable of releasing a volatile compound capable of forming an aerosol, and can release the volatile compound by heating the aerosol generating substrate.

[0027] The aerosol-forming substrate may be a solid-state aerosol-forming substrate. Alternatively, the aerosol-forming substrate may comprise solid and liquid-state components. The aerosol-forming substrate may comprise a tobacco material, which includes volatile tobacco flavor compounds released from the substrate upon heating. Alternatively, the aerosol-forming substrate may comprise a non-tobacco material. The aerosol-forming substrate may further comprise an aerosol-forming agent. Examples of suitable aerosol-forming agents are glycerin and propylene glycol.

[0028] The aerosol generated by heating the tobacco section (102) is transported to the user through the filter section (101), and the filter section (101) may be an acetic acid cellulose filter. The filter section (101) may provide a fragrance by spraying a seasoning liquid, or the duration of the flavor transported to the user may be improved by inserting a separated fiber coated with the seasoning liquid into the filter section (101). The filter section (101) may also be equipped with a spherical or cylindrical capsule, and the capsule may contain the contents of a seasoning substance.

[0029] In FIG. 2, only a portion of the aerosol generating product (100) related to the present embodiment is illustrated. Correspondingly, those skilled in the art related to the present embodiment will understand that the aerosol generating product (100) may include general-purpose parts other than those illustrated in FIG. 2. For example, it may include a cooling section for cooling the aerosol heated in the tobacco section (102), thereby allowing the user to inhale the aerosol cooled to a suitable temperature.

[0030] A label (C1) is provided on the outer surface of the filter section (101) at the boundary position with the tobacco section (102). The color of the label (C1) may be a single color, for example, red, blue, green, etc., or it may be a mixed color. The color of the label (C1) may indicate one flavor (not limited to a type) of different aerosol generating products (100); for example, red indicates a mint-flavored aerosol generating product, blue indicates a coffee-flavored aerosol generating product, and green indicates a mango-flavored aerosol generating product. The color of the label (C1) and the color of the outer surface of the tobacco section (102) are different, which is advantageous for detection identification by the color detection device.

[0031] FIG. 3 is an exploded view of an aerosol generating device provided by an embodiment of the present application.

[0032] As shown in FIG. 3, the aerosol generating device (200) includes a shell (6) and a heater (1), and the heater (1) is provided inside the shell (6).

[0033] The shell (6) includes a case (61), a fixed case (62), a base (63), and a bottom cover (64), and both the fixed case (62) and the base (63) are fixed within the case (61), wherein the base (63) is for fixing the base body (11), and the base (63) is provided within the fixed case (62), and the bottom cover (64) is provided at one end of the case (61) and also covers the case (61).

[0034] Specifically, the base (63) includes a base (631) that is sleeve-connected to the upper part of the base body (11) and a base (632) that is sleeve-connected to the lower part of the base body (11). Both the base (631) and the base (632) are provided within a fixed case (62). An inlet pipe (641) is provided protruding from the bottom cover (64). The inlet pipe (641) is connected to one end of the base (632) that is far from the base (631). The base (631), heater (1), base (632), and inlet pipe (641) are provided coaxially. Additionally, the space between the heater (1), the base (621), and the base (632) can be sealed through a sealing part, and the base (632) and the inlet pipe (641) can also be sealed. The inlet pipe (641) is in communication with external air, allowing for smooth inhalation when the user inhales.

[0035] The aerosol generating device (200) further includes a control circuit board (3) and a battery (7). The fixed case (62) includes a front case (621) and a rear case (622), and an opening (A) is provided on the rear case (622). The front case (621) is fixedly connected to the rear case (622). Both the control circuit board (3) and the battery (7) are provided within the fixed case (62). The battery (7) is electrically connected to the control circuit board (3), and a button (4) is provided protruding on the case (61). A charging interface (31) is further connected to the control circuit board (3), and the charging interface (31) is exposed on the fixed case (64). A user can charge or upgrade the aerosol generating device (200) through the charging interface (31) to ensure continuous use of the aerosol generating device (200).

[0036] The battery (7) provides power for operating the aerosol generating device (200). For example, the battery (7) can provide power to heat the heater (1) and also provide power required for operating the controller. The battery (7) may be a lithium iron phosphate (LiFePO4) battery. For example, the battery (7) may be a lithium cobaltate (LiCoO2) battery or a lithium titanate battery. The battery (7) may be a rechargeable battery or a disposable battery.

[0037] The aerosol generating device (200) further includes an insulating tube (5), the insulating tube (5) is provided within a fixed case (62), the insulating tube (5) is provided on the outer edge of a base body (11), and the insulating tube (5) prevents a large amount of heat from being transferred onto the case (61) and causing the user to feel a stinging sensation in their hand. The insulating tube includes an insulating material, and the insulating material may be an insulating adhesive, aerogel, aerogel felt, asbestos, aluminum silicate, calcium silicate, diatomaceous earth, zirconium oxide, etc. The insulating tube may also be a vacuum insulating tube. An infrared reflective coating layer may be further formed within the insulating tube (5) to improve heating efficiency.

[0038] The aerosol generating device (200) further includes a temperature sensor (2), for example, an NTC temperature sensor, to detect the real-time temperature of the heater (1) and transmit the detected real-time temperature to a control circuit board (3), and the control circuit board (3) adjusts the magnitude of the current flowing through the heater (1) based on the corresponding real-time temperature.

[0039] Specifically, when the NTC temperature sensor detects that the real-time temperature of the heater (1) is relatively low, for example, when it detects that the temperature of the heater (1) is less than 150°C, the control circuit board (3) controls the battery (7) to output a relatively high voltage to the heater (1), and further increases the heating power of the aerosol-forming substrate, thereby reducing the waiting time required for the user to inhale the first bite.

[0040] When the NTC temperature sensor detects that the temperature of the heater (1) is 150℃ - 200℃, the control circuit board (3) controls the battery (7) to output a normal voltage to the heater (1).

[0041] When the NTC temperature sensor detects that the temperature of the heater (1) is 200℃ - 250℃, the control circuit board (3) controls the battery (7) to output a relatively low voltage to the heater (1).

[0042] When the NTC temperature sensor detects that the temperature of the heater (1) is 250°C or higher, the control circuit board (3) controls the battery (7) to stop outputting voltage to the heater (1).

[0043] FIG. 4 is a drawing of some parts of an aerosol generating device provided by an embodiment of the present application, FIG. 5 is a cross-sectional view of some parts of an aerosol generating device provided by an embodiment of the present application, and FIG. 6 is a drawing of a heater of an aerosol generating device provided by an embodiment of the present application.

[0044] As shown in FIGS. 4 and FIGS. 6, the aerosol generating device (200) further includes a heater (1) and a color detection device, and the color detection device includes a light source (201) and a color sensor (202).

[0045] The heater (1) is intended to heat at least a portion of the aerosol generating product (100) received in the cavity of the aerosol generating device (200) to generate an aerosol for inhalation.

[0046] The heater (1) may be a central heating method (through direct contact between the outer circumference of the heating body and the aerosol-forming substrate) and an outer periphery heating method (where a cylinder-shaped heating body surrounds the aerosol-forming substrate), and the heater may also generate an inhalable aerosol by heating the aerosol-forming substrate through one or several methods among heat conduction, electromagnetic induction, chemical reaction, infrared action, resonance, photoelectric conversion, and photothermal conversion.

[0047] The explanation proceeds by taking the heater (1) below as an example of an infrared heater.

[0048] As shown in FIG. 6, the heater (1) includes a base body (11), an infrared heat coating layer (12), and an electrically conductive element (13).

[0049] The base body (11) may be cylindrical, truncated pyramidal, or other columnar shapes, preferably cylindrical. The interior of the base body (11) is hollow, and the hollow portion constitutes at least a part of the cavity of the aerosol generating device (200). The base (631) at the top of the base body (11) has a through hole corresponding to the hollow portion, and the aerosol generating product (100) may be sequentially removed from the middle portion or inserted into the hollow portion through the opening (A) and the through hole.

[0050] An infrared heat-generating coating layer (12) is formed on the outer surface of a base body, and the infrared heat-generating coating layer (12) receives power from a battery (7) through an electrically conductive element (13) to generate heat, and transfers the generated heat to an aerosol generating product inserted into a cavity at least by means of infrared radiation.

[0051] The electrically conductive element (13) includes a first electrode (131) and a second electrode (132) provided on a base body (11), and both the first electrode (131) and the second electrode (132) are electrically connected to an infrared heat coating layer (12). The first electrode (131) and the second electrode (132) may be a circular ring-shaped electrically conductive coating layer coated on an outer surface that is close to the upper and lower ends of the base body (11), and the electrically conductive coating layer may be a metal coating layer or an electrically conductive tape, etc., and the metal coating layer may include silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium, or the above metal alloy material.

[0052] As illustrated in FIGS. 4 and 5, a light source (201) and a color sensor (202) are provided in a through hole of the base (631), and when an aerosol generating product (100) is inserted into a cavity of the aerosol generating device (200) in a fixed position, the location where the color sensor (202) is provided corresponds to the label (C1) of the aerosol generating product (100). The light source (201) is configured to emit light into the cavity of the aerosol generating device (200), that is, into the through hole of the base (631); and the color sensor (202) is configured to generate a color signal by detecting the reflection of the light.

[0053] In the example, the light source (201) may be an LED lamp. The color sensor (202) may include a color filter and a photoelectric detector, and through the color filter and the photoelectric detector, it performs a color analysis on the reflection of the light and generates a corresponding color signal. The photoelectric detector includes, but is not limited to, a photoelectric diode, a photoconductive resistor, a photoelectric transistor, etc. As should be explained, the structure of the color sensor (202) is not limited in this case. The light source (201) and the color sensor (202) may be provided independently or may be combined directly.

[0054] The aerosol generating device (200) further includes a controller, and the controller can control the overall operation of the aerosol generating device (200). To explain in detail, the controller controls the operation of the battery (7) and the heater (1), as well as the operation of other components in the aerosol generating device (200). Furthermore, the controller can determine whether to proceed with the operation of the aerosol generating device (200) by inspecting the state of the components of the aerosol generating device (200). In this example, the controller acquires a color signal generated by the color sensor (202), and generates a control signal based on the color signal to control the operation of the heater (1).

[0055] The controller includes at least one processor. The processor may include an array of logic gates, or may include a combination of a general-purpose microprocessor and memory that stores a program executable on the microprocessor. And, those skilled in the art will understand that the controller may include other types of hardware.

[0056] In one example, the aerosol generating device (200) is,

[0057] It further includes an input module that receives a turn-on command entered by a user and generates a turn-on signal;

[0058] The controller is also configured to receive the turn-on signal and to control the turn-on of the light source (201) and the color detection device (202) by the turn-on signal.

[0059] In the example, the input module may be the button (4) shown in FIG. 3, but is not limited to this case.

[0060] When understood in conjunction with FIGS. 1-6, in one example, the controller also generates a product position insertion signal when it sequentially acquires a second color signal and a first color signal generated by the sensor (202) within a first predetermined time; and is configured to control the heater (1) to activate heating by means of the product position insertion signal.

[0061] Specifically, when the aerosol generating product (100) is sequentially inserted into the hollow portion of the base body (11) through the opening (A) and the through hole of the base (631), light emitted by the light source (201) is irradiated onto the aerosol generating product (100), and the color sensor (202) sequentially detects the color of the outer surface of the tobacco section (102) and the color of the label (C1), and also generates a corresponding second color signal and a first color signal. When the controller acquires the second color signal and the first color signal, it can determine that the aerosol generating product (100) is inserted into the cavity of the aerosol generating device (200) in the correct position, and further generates a product insertion signal in the correct position. After that, the heater (1) is controlled through the product insertion signal in the correct position to automatically start heating.

[0062] Furthermore, the above controller also,

[0063] The type of aerosol generating product (100) received in the cavity is determined by the first color signal; temperature configuration information corresponding to the type of aerosol generating product (100) is determined by the type of aerosol generating product (100); and power supplied to the heater is controlled by the temperature configuration information.

[0064] Specifically, the color of the label (C1) can indicate one flavor of different aerosol generating products (100), for example, red indicates a peppermint-flavored aerosol generating product, blue indicates a coffee-flavored aerosol generating product, and green indicates a mango-flavored aerosol generating product. When the first color signal is obtained through the color sensor (202), a corresponding heating curve, i.e., temperature configuration information, can be selected from among the pre-stored heating curves. Then, the heater (1) is controlled according to the corresponding heating curve to proceed with heating, thereby allowing the user to obtain the optimal flavor.

[0065] Furthermore, the above controller also,

[0066] When the second color signal and the third color signal generated by the color sensor (202) are acquired sequentially within a second predetermined time, a product pull-out signal is generated; and the heater is controlled to stop heating based on the product pull-out signal.

[0067] Specifically, after automatically heating by controlling the heater (1), if the user pulls out the aerosol generating product (100) from the cavity of the aerosol generating device (200), the color sensor (202) sequentially detects the color of the outer surface of the tobacco section (102) and the color of the inner wall of the cavity, and generates a corresponding second color signal and a third color signal. When the controller sequentially acquires the second color signal and the third color signal, it can determine that the aerosol generating product (100) has been removed from the cavity of the aerosol generating device (200), and further generates a product pull-out signal and controls the controller (1) to stop heating.

[0068] Furthermore, the above controller also,

[0069] If only the second color signal generated by the color sensor (202) is acquired within a second predetermined time, a product position insertion error signal is generated; and based on the product position insertion error signal, the heater is controlled to stop heating and the heating time already completed by the heater is recorded.

[0070] Specifically, after automatically heating by controlling the heater (1), if the aerosol generating product (100) unexpectedly pulls out and the aerosol generating product (100) is not inserted into the cavity of the aerosol generating device (200), the color sensor (202) can detect only the color of the outer surface of the tobacco section (102) and generate a corresponding second color signal. When the controller acquires the second color signal, it can determine that the aerosol generating product (100) was not inserted into the correct position, generate a product insertion error signal, control the heater (1) to stop heating, and also record the heating time that the heater (1) has already completed.

[0071] Furthermore, the above controller also,

[0072] It is configured to control the heater (1) to stop heating and then generate first notification information;

[0073] The aerosol generating device (200) is,

[0074] It further includes a first notification module that acquires the above first notification information and notifies the user that there is an abnormality in the location of the aerosol generating product (100).

[0075] Specifically, after the heater (1) starts heating, if the aerosol generating product (100) unexpectedly pulls out and the heater (1) stops heating, the user can be notified that there is an abnormality in the position of the aerosol generating product (100) through methods such as vibration, light, or sound, and can re-insert the aerosol generating product (100) into the cavity in the correct position.

[0076] Furthermore, the above controller also,

[0077] When the second color signal and the first color signal generated by the color sensor (202) are acquired sequentially within a third predetermined time, a product reposition insertion signal is generated; the remaining heating time of the heater is calculated based on the heating time already completed by the heater; and the heater is controlled to proceed with heating based on the product reposition insertion signal and the remaining heating time of the heater.

[0078] If the user inserts the aerosol generating product (100) into the cavity again, heating can be continued for the aerosol generating product (100), and the user does not need to operate the heating, thereby simplifying the operation of the aerosol generating device (200) and improving the user's product.

[0079] Furthermore, the above controller also,

[0080] If only the second color signal generated by the color sensor (202) is acquired within a first predetermined time, or if the second color signal and the fourth color signal generated by the color sensor (202) are acquired sequentially within a first predetermined time, the controller is configured to be controlled to be turned off.

[0081] Specifically, if only the second color signal generated by the color sensor (202) is acquired within the first predetermined time, it can be considered that the aerosol generating product (100) has not been inserted in the correct position. In this case, since there is no need to control the heater (1) to activate heating, the heater (1) is controlled to turn off. Alternatively, if the second color signal and the fourth signal generated by the color sensor (202) are acquired sequentially within the first predetermined time, it can be considered that an aerosol generating product that does not match the aerosol generating device (200) has been inserted. In this case, too, since there is no need to control the heater (1) to activate heating, the heater (1) is controlled to turn off. Here, the fourth color is different from the color of the aforementioned label (C1), and is also different from the color of the outer surface of the tobacco section (102) and the color of the inner wall of the cavity.

[0082] As to be explained, the first preset time, the second preset time, and the third preset time may be empirical values, which are already set at the time of shipment of the aerosol generating device (200), or which are set by the user.

[0083] Furthermore, the above controller also,

[0084] When only the second color signal generated by the color sensor (202) is acquired within a first predetermined time, or when the second color signal and the fourth color signal generated by the color sensor (202) are acquired sequentially within a first predetermined time, the second notification information is generated;

[0085] The above aerosol generating device (200) is,

[0086] It further includes a second notification module that receives the above second notification information and also notifies the user that there is an abnormality.

[0087] FIG. 7 is a flowchart of a control method for an aerosol generating device provided by an embodiment of the present application. The method includes the following steps.

[0088] Step S11: Acquire the color signal generated by the color detection device.

[0089] Step S12: A control signal is generated based on the above color signal to control the operation of the heater.

[0090] The overall control process of the aerosol generating device (200) will be explained in conjunction with Fig. 8 below.

[0091] Step S21: Inserting the cigarette;

[0092] Step S22: Detects whether a cigarette has been inserted;

[0093] Specifically, when a cigarette is inserted, the color sensor (202) detects the color of the outer surface of the tobacco section (102) and also generates a corresponding second color signal, that is, it can be determined that a cigarette has been inserted.

[0094] Step S23: Continue inserting the cigarette;

[0095] Step S24: Detect whether the cigarette is inserted in the correct position;

[0096] S25: The heater starts heating;

[0097] Specifically, when the cigarette is inserted into the cavity in the correct position, the color sensor (202) sequentially detects the color of the outer surface of the tobacco section (102) and the color of the label (C1), and also generates a corresponding second color signal and a first color signal.

[0098] Step S26: When the cigarette is inserted into the cavity in the correct position, the controller controls the heater to activate heating;

[0099] Step S261, Step S27: The heating of the cigarette is completed, the cigarette is pulled out, and the heating is terminated;

[0100] Steps S262, S263, and S27: If the cigarette abnormally deviates from the insertion position, the control controls the heater to stop heating; at this time, if the cigarette is pulled out, heating is terminated.
