Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202010801561.7, filed with the China National Intellectual Property Administration on August 11, 2020 and entitled "AEROSOL-GENERATION DEVICE, AND METHOD AND SYSTEM THEREOF", which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments of this application relate to the field of cigarette device technologies, and in particular, to an aerosol-generation device, and a method and system thereof.

BACKGROUND

Tobacco products such as cigarettes and cigars bum tobacco during use to produce smoke. Attempts have been made to provide alternatives for these tobacco-burning products by manufacturing products that release compounds without being burnt. An example of the products is a so-called heat not burning product that releases a compound by heating rather than burning a tobacco.
To simplify a user's operation, existing cigarette devices generally install a sensor at a cigarette insertion port to detect whether there is a cigarette inserted, and then control a heater to start heating. However, the sensor cannot detect whether the cigarette is inserted in place, and if heating is started when the cigarette is not inserted in place, the cigarette is prone to not be effectively heated, thereby affecting inhalation experience. A solution is to add another sensor in a cigarette cavity to detect whether the cigarette is inserted in place. However, increasing the sensor leads to an increase in hardware cost of the cigarette device, which reduces competitiveness of the product.

Specifically, the base 63 includes a base 631 sleeved at an upper end of the substrate 11 and a base 632 sleeved at a lower end of the substrate 11. Both the base 631 and the base 632 are arranged in the fixing housing 62. The bottom cover 64 is convexly provided with an air inlet tube 641. One end of the base 632 away from the base 631 is connected to the air inlet tube 641. The base 631, the heater 1, the base 632, and the air inlet tube 641 are arranged coaxially, and the heater 1 can be sealed with the base 631 and the base 632 through a sealing member, the base 632 and the air inlet tube 641 can also be sealed, and the air inlet tube 641 is communicated with external air so that the user can smoothly take in air when inhaling.
The aerosol-generation device 200 further includes a control circuit board 3 and a battery 7. The fixing housing 62 includes a front housing 621 and a rear housing 622. The rear housing 622 is provided with an opening A, and the front housing 621 is fixedly connected to the rear housing 622. Both the control circuit board 3 and the battery 7 are arranged in the fixing housing 62, and the battery 7 is electrically connected to the control circuit board 3. A button 4 is convexly arranged on the outer housing 61. The control circuit board 3 is further connected to a charging interface 31, the charging interface 31 is exposed on the bottom cap 64, and the user may charge or upgrade the aerosol-generation device 200 through the charging interface 31, to ensure continuous use of the aerosol-generation device 200.
The battery 7 provides power for operating the aerosol-generation device 200. For example, the battery 7 can provide power to heat the heater 1, and can provide power required to operate the controller. The battery 7 may be, but is not limited to, 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.
The aerosol-generation device 200 further includes a thermal insulation tube 5, the thermal insulation tube 5 is arranged in the fixing housing 62, and the thermal insulation tube 5 is arranged on a periphery of the substrate 11. The thermal insulation tube 5 can prevent a large amount of heat from being transferred to the outer housing 61, causing the user to feel hot.

As shown in FIG. 4 to FIG. 6, the aerosol-generation device 200 further includes a heater 1 and a color detection apparatus. The color detection apparatus includes a light source 201 and a color sensor 202.
The heater 1 is configured to heat at least a part of an aerosol-generation product 100 received in a cavity of the aerosol-generation device 200 to generate an aerosol for inhalation.
The heater 1 may use a central heating method (a periphery of a heating body is in direct contact with the aerosol-generation substrate) and a peripheral heating method (a cylindrical heating body wraps the aerosol-generation substrate). The heater can further heat the aerosol-generation substrate through one or more of the following methods: heat conduction, electromagnetic induction, chemical reaction, infrared action, resonance, photoelectric conversion, and photothermal conversion to generate an aerosol for inhalation.
A description is made below by using an example in which the heater 1 is an infrared heater.
As shown in FIG. 6, the heater 1 includes a substrate 11, an infrared electrothermal coating 12, and a conducive element 13.
The substrate 11 may be in a shape of a cylinder, a prism, or another column, preferably a cylinder. The substrate 11 is hollow inside, and the hollow part at least forms a part of the cavity of the aerosol-generation device 200. A base 631 at an upper end of the substrate 11 is provided with a through hole corresponding to the hollow part, and the aerosol-generation product 100 can be removed from or inserted into the hollow part by sequentially passing through the opening A and the through hole.
The infrared electrothermal coating 12 is formed on an outer surface of the substrate. The infrared electrothermal coating 12 receives electric power of the battery 7 through the conducive element 13 to generate heat, and transfers the generated heat to the aerosol-generation product inserted into the cavity at least in a manner of infrared radiation.
The conducive element 13 includes a first electrode 131 and a second electrode 132 arranged on the substrate 11, and both the first electrode 131 and the second electrode 132 are electrically connected to the infrared electrothermal coating 12. The first electrode 131 and the second electrode 132 may be an annular conductive coating coated on the outer surface of the substrate 11 near upper and lower ends. The conductive coating is a metallic coating, a conductive tape, or the like, and the metallic coating may include silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium or alloy materials of the foregoing metals.
As shown in FIG. 4 to FIG. 5, a light source 201 and a color sensor 202 are arranged in a through hole of a base 631. When an aerosol-generation product 100 is inserted into a cavity of an aerosol-generation device 200 in place, the color sensor 202 is positioned to correspond to a label C1 of the aerosol-generation product 100. The light source 201 is configured to emit light to the cavity of the aerosol-generation device 200, that is, into the through hole of the base 631; and the color sensor 202 is configured to detect reflection of the light to generate a color signal.
In this example, the light source 201 may be an LED light. The color sensor 202 may include a color filter and a photoelectric converter, and the color in the reflection of the light is detected through the color filter and a photoelectric detector, and a corresponding color signal is generated. The photoelectric detector includes, but is not limited to, a photodiode, a photoresistor, a phototransistor, and the like. It should be noted that, the configuration of the color sensor 202 is not limited to this case. The light source 201 and the color sensor 202 can be arranged independently, or it is also feasible to integrate the two together.
The aerosol-generation device 200 further includes a controller, and the controller can control an overall operation of the aerosol-generation device 200. In detail, the controller not only controls operations of the battery 7 and the heater 1, but also controls operations of other elements in the aerosol-generation device 200. In addition, the controller can determine whether the aerosol-generation device 200 is operable by checking states of the elements of the aerosol-generation device 200. In this example, the controller obtains a color signal generated by the color sensor 202, and generates a control signal according to the color signal to control operation of the heater 1.
The controller includes at least one processor. The processor may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory for storing an executable program in a microprocessor. In addition, a person skilled in the art should understand that the controller may include hardware of another type.
In an example, the aerosol-generation device 200 further includes:

an input module, configured to receive a start instruction inputted by a user to generate a start signal; and
a micro controller, configured to receive the start signal, and control the light source 201 and the color sensor 202 to start according to the start signal.

In this example, the input module may be the button 4 shown in FIG. 3, but is not limited to this case.
With reference to FIG. 1 to FIG. 6, in an example, the controller is further configured to generate a product inserted-in-place signal in a case that a second color signal and a first color signal generated by the color sensor 202 are sequentially obtained within a first preset time; and control the heater 1 to start heating according to the product inserted-in-place signal.
Specifically, when an aerosol-generation product 100 is inserted into a hollow part of a substrate 11 sequentially through an opening A and a through hole of a base 631, light emitted by a light source 201 irradiates the aerosol-generation product 100, a color sensor 202 sequentially detects the color of an outer surface of a tobacco segment 102 and the color of a label C1, and generates a corresponding second color signal and first color signal. When the controller obtains the second color signal and the first color signal, it can be determined that the aerosol-generation product 100 is inserted into a cavity of the aerosol-generation device 200 in place, so that the product inserted-in-place signal is generated, and then the heater 1 is controlled to automatically start heating according to the product inserted-in-place signal. Further, the controller is further configured to:
determine a type of the aerosol-generation product 100 received in the cavity according to the first color signal; determine corresponding temperature configuration information according to the type of the aerosol-generation product 100; and control power supplied to the heater 1 according to the temperature configuration information.
Specifically, the color of the label C1 may represent a flavor of different aerosol-generation products 100, for example: red represents a mint-flavored aerosol-generation product, blue represents a coffee-flavored aerosol-generation product, green represents a mango-flavored aerosol-generation product, and the like. When the first color signal is obtained through the color sensor 202, a corresponding heating curve may be selected from pre-stored heating curves, that is, temperature configuration information, and then the heater 1 is controlled to heat according to the heating curve, so that the user can obtain a best taste.
Further, the controller is further configured to:
generate a product pull-out signal in a case that the second color signal and a third color signal generated by the color sensor 202 are sequentially obtained within a second preset time; and control the heater 1 to stop heating according to the product pull-out signal.
Specifically, after the heater 1 is controlled to automatically start heating, if the user pulls the aerosol-generation product 100 out of the cavity of the aerosol-generation device 200, the color sensor 202 sequentially detects the color of an outer surface of a tobacco segment 102 and the color of an inner wall of the cavity, and generates a corresponding second color signal and third color signal. When the controller sequentially obtains the second color signal and the third color signal, it can be determined that the aerosol-generation product 100 is removed from the cavity of the aerosol-generation device 200, so that the product pull-out signal is generated and the heater 1 is controlled to stop heating.
Further, the controller is further configured to:
generate a product non-inserted-in-place signal in a case that only the second color signal generated by the color sensor 202 is obtained within a second preset time; and control the heater to stop heating and record a completed heating time of the heater according to the product non-inserted-in-place signal.
Specifically, after the heater 1 is controlled to automatically start heating, if the aerosol-generation product 100 is accidentally moved, the aerosol-generation product 100 is not inserted into the cavity of the aerosol-generation device 200 in place. In this case, the color sensor 202 can only detect the color of the outer surface of the tobacco segment 102, and generate a corresponding second color signal. When the controller obtains the second color signal, it can be determined that the aerosol-generation product 100 is not inserted in place, so that the product non-inserted-in-place signal is generated, and the heater 1 is controlled to stop heating and a completed heating time of the heater 1 is recorded.
Further, the controller is further configured to:

generate first prompt information after the heater 1 is controlled to stop heating; and
the aerosol-generation device 200 further includes:
a first prompt module, configured to obtain the first prompt information and prompt the user that there is an abnormality in a position of the aerosol-generation product 100.

Specifically, after the heater 1 starts heating, if the aerosol-generation product 100 is accidentally moved, the heater 1 is caused to stop heating. In this case, the user can be reminded of the abnormality of the position of the aerosol-generation product 100 through vibration, light, sound, or the like, so as to facilitate the user to reinsert the aerosol-generation product 100 into the cavity in place.
Further, the controller is further configured to:
generate a product reinserted-in-place signal in a case that the second color signal and the first color signal generated by the color sensor 202 are sequentially obtained within a third preset time; calculate a remaining heating time of the heater according to the completed heating time of the heater; and control the heater 1 to perform heating according to the product reinserted-in-place signal and the remaining heating time of the heater.
Specifically, after the heater 1 starts heating, if the aerosol-generation product 100 is accidentally moved, the heater 1 is caused to stop heating. If the user reinserts the aerosol-generation product 100 into the cavity in place, the aerosol-generation product 100 can continue to be heated without the user starting the heating, which further simplifies the operation of the aerosol-generation device 200 and improves the user experience.
Further, the controller is further configured to:
control the heater 1 to be in an off state in a case that only the second color signal generated by the color sensor 202 is obtained within the first preset time or in a case that the second color signal and a fourth color signal generated by the color sensor 202 are sequentially obtained within the first preset time.
Specifically, in a case that only the second color signal generated by the color sensor 202 is obtained within the first preset time, it can be determined that the aerosol-generation product 100 is not inserted in place. In this case, there is no need to control the heater 1 to start heating, that is, to control the heater 1 to be in the off state. Alternatively, when the second color signal and the fourth color signal generated by the color sensor 202 are sequentially obtained within the first preset time, it can be determined that an aerosol-generation product that does not match the aerosol-generation device 200 is inserted. In this case, there is also no need to control the heater 1 to start heating, that is, to control the heater 1 to be in the off state. A fourth color is different from the color of the foregoing label C1, and also different from the color of the outer surface of the tobacco segment 102 and the color of the inner wall of the cavity.
It should be noted that, the first preset time, second preset time and third preset time above may be empirical values, which have been set when the aerosol-generation device 200 leaves the factory; or set by the user.
Further, the controller is further configured to:

generate second prompt information in a case that only the second color signal generated by the color sensor 202 is obtained within the first preset time or in a case that the second color signal and the fourth color signal generated by the color sensor 202 are sequentially obtained within the first preset time; and
the aerosol-generation device 200 further includes:
a second prompt module, configured to receive the second prompt information and prompt the user that there is an abnormality.

FIG. 7 is a schematic flowchart of a method for controlling an aerosol-generation device according to an implementation of this application. The method includes:

Step S11: Obtain a color signal generated by a color detection apparatus.
Step S12: Generate a control signal according to the color signal to control operation of a heater.

An overall control process of the aerosol-generation device 200 is described below with reference to FIG. 8.
Step S21: Insert a cigarette.
Step S22: Detect whether the cigarette is inserted.
Specifically, when the cigarette is inserted, a color sensor 202 detects a color of an outer surface of a tobacco segment 102 and generates a corresponding second color signal, which can determine that the cigarette is inserted.
Step S23: Continue to insert the cigarette.
Step S25: Detect whether the cigarette is inserted in place.
Specifically, when the cigarette is inserted into a cavity in place, the color sensor 202 sequentially detects the color of the outer surface of the tobacco segment 102 and a color of a label C1, and generates a corresponding second color signal and first color signal.
Step S26: When the cigarette is inserted into the cavity in place, a controller controls a heater to start heating.
Step S261 and Step S27: The heating of the cigarette is completed and the cigarette is pulled out, and the heating ends.
Step S262, Step S263, and Step S27: The cigarette is abnormally out of an insertion position, and the controller controls the heater to stop heating. In this case, if the cigarette is pulled out, the heating ends.
