Description

TECHNICAL FIELD

The present disclosure relates to the field of heating without combustion, and in particular to an aerosol generating device, a heating assembly and a storage assembly.

BACKGROUND

Most of the aerosol generating devices that involve heating without combustion in the art may take heating elements to heat aerosol generating substrates, generating a continuous fuming effect, such that a user may inhale the aerosol.

The skilled person in the art shall understand explicitly and implicitly that the embodiments described herein may be combined with other embodiments.
As shown inFIGS. 1 and 2, FIG. 1 is a structural schematic view of an aerosol generating device according to a first embodiment of the present disclosure, andFIG. 2 is another structural schematic view of the aerosol generating device according to a first embodiment of the present disclosure. A left half portion ofFIG. 2 represents an overall schematic view of theaerosol generating device 10. A right half portion ofFIG. 2 represents an explosive view of theaerosol generating device 10. Theaerosol generating device 10 includes abody 11, aheating assembly 12, and a storage assembly 13 (not shown inFIG. 2). Thebody 11 and theheating assembly 12 are detachably connected. Thebody 11 and thestorage assembly 13 are detachably connected.
In an embodiment, in detail, thebody 11 includes afirst body portion 11a and asecond body portion 11b. Thefirst body portion 11a is configured to receive a battery. Thesecond body portion 11b is configured to receive a controller, a storage assembly, and so on. Thesecond body portion 11b is configured to connect to theheating assembly 12. For example, thesecond body portion 11b is arranged with a first connection member, and theheating assembly 12 is arranged with a second connection member. The first connection member and the second connection member are configured to allow thesecond body portion 11b to be connected to theheating assembly 12. In an embodiment, the connection member may be a snap, a screw, or the like. In addition, theheating assembly 12 may be connected to thefirst body portion 11a through a bottom of theheating assembly 12.
In an embodiment, theaerosol generating device 10 further includes afirst cover 14 and asecond cover 15 that are detachably connected to thebody 11. When theheating assembly 12 is fixedly connected to thebody 11, thefirst cover 14 may cover theheating assembly 12 to protect theheating assembly 12. Further, thesecond cover 15 may cover the heating assembly 12 (or the first cover 14) and thesecond body portion 11b to protect theheating assembly 12 and thesecond body portion 11b.
In the present disclosure, theheating assembly 12 is detachably connected to thebody 11. Thestorage assembly 13 stores a feature parameter. The feature parameter corresponds to one model of theheating assembly 12. Thebody 11 is configured to obtain the feature parameter from thestorage assembly 13, and heat theheating assembly 12 based on the feature parameter, such that theheating assembly 12 is taken to heat the aerosol generating substrate to generate the aerosol.
Further, in detail, thebody 11 includes a housing assembly and a controller received inside the housing assembly. Theheating assembly 12 and thestorage assembly 13 are detachably connected to the housing assembly. When theheating assembly 12 and thestorage assembly 13 are connected to the housing assembly, theheating assembly 12 and thestorage assembly 13 are electrically connected to the controller. The controller is configured to obtain the feature parameter from thestorage assembly 13 and to heat theheating assembly 12 based on the feature parameter, allowing theheating assembly 12 to heat the aerosol generating substrate to generate the aerosol.
In an embodiment, thestorage assembly 13 stores the feature parameter, and the feature parameter corresponds to one model of theheating assembly 12. Since the feature parameter is fixed, theheating assembly 12 matching with the feature parameter may be heated only based on the feature parameter. In this way, when a model of aconnected heating assembly 12 does not match the model corresponding to the feature parameter, theconnected heating assembly 12 may not heat the aerosol generating substrate properly, such that a taste of the aerosol to be inhaled may be unsatisfying. In this way, randomly changing the model of theheating assembly 12 may be avoided. When the user replaces theheating assembly 12, only theheating assembly 12 in a same model may be replaced.
In an embodiment, the feature parameter includes a parameter of a heating body in theheating assembly 12 and a heating parameter. The parameter of the heating body indicates correspondence between a resistance value of the heating body and a temperature of the heating body.
The parameter of the heating body may be formed based on various models ofheating assemblies 12. Material of the heating body, a process of manufacturing the heating body, a device for manufacturing the heating body and other factors causes feature parameters (such as a temperature T - resistance R curve, an initial resistance value R0, a temperature coefficient of resistance (TCR), and so on) of various models of heating bodies to be various. While manufacturing the product, theheating assembly 12 may be placed in a test device, and feature parameters of the various models of theheating assemblies 12 may be tested.
The heating parameter may be a "temperature-time variation curve", configured to determine that the heating body is heated in various extent as time passes. As shown inFIG. 3, a schematic view of a temperature-time variation curve according to an embodiment of the present disclosure is shown.
For example, the controller may control the temperature of the heating body based on a preset temperature-time curve and by applying a PID algorithm. The "temperature-time" curve refers to a heating curve of tobacco.
A specific scenario will be described in the following to illustrate the present embodiment.
When the user uses an electronic cigarette device for smoking, thebody 11 may be connected to theheating assembly 12 firstly. For example, a switch button arranged on thebody 11 may be switched on. In this way, the electronic cigarette device starts to operate.
Thebody 11 obtains the feature parameter in thestorage component 13, obtains correspondence between the resistance value and the temperature of the heating body in theheating assembly 12, and starts timing. Subsequently, a current resistance value of the heating body may be obtained, and a current temperature may be obtained based on the parameter of the heating body. Finally, a voltage of the heating body may be controlled based on the "temperature-time" curve.
It shall be understood that, generally, in order to obtain a better taste by heating the aerosol generating substrate (such as tobacco), a temperature required to heat the aerosol generating substrate may be variable in various time periods. In an embodiment, as shown inFIG. 3, a horizontal axis indicates the time, and a vertical axis indicates the temperature.
In a time period T0-T1, the heating body may be heated, and a temperature of the heating body rises from a room temperature W0 to a temperature W1.
In a time period T1-T2, the temperature of the heating body remains at the temperature W1.
In a time period T2-T3, the temperature of the heating body may be reduced, and the temperature of the heating body decreases from the temperature W1 to a temperature W2.
In a time period T3-T4, the temperature of the heating body remains at the temperature W2.
After the time point T4, the temperature of the heating body is reduced, and the temperature of the heating body decreases from the temperature W2 to the room temperature.
In an embodiment, a value of the T1 may be 5s to 10s, a value of the T2 may be 12s to 18s, a value of the W1 may be 320°C to 360°C, and a value of the W2 may be 300°C to 340°C.
In an embodiment, T1=7s, T2=15s, W1=340°C, and W2=320°C. In this case, when the temperature of the heating body decreases by 1°C, the resistance of the heating body decreases by 2.28mQ accordingly. Therefore, when the temperature of the heating body decreases from the temperature W1 to the temperature W2, i.e., decreases by 20°C, the resistance value of the heating body needs to be decreased by 20*2.28mQ.
Further, while taking electrical energy to control the temperature for heating the heating body, a pulse frequency and/or a pulse amplitude and/or a duty cycle of the electrical energy supplied to the heating body may be variable to control the temperature of the heating body. In this way, the aerosol generating device may be controlled to release an aerosol having a better taste. As shown inFIG. 4, FIG. 4 is a schematic view of a pulse voltage according to the present disclosure. For example, in a time period t1, an enable switch may be switched on, and the battery may provide electrical energy to the heating body. In a time period t2, an enable switch may be switched off, and the battery may not provide electrical energy to the heating body. Therefore, a percentage of the time period t1 over the time period T may be adjusted to further adjust the temperature of the heating body. In detail, when the duty cycle of the time period t1 is increased, the temperature of the heating body may be increased, and when the duty cycle of the time period t1 is decreased, the temperature of the heating body may be decreased.
In another embodiment, thestorage assembly 13 stores the feature parameter and an anti-counterfeiting parameter. The feature parameter and the anti-counterfeiting parameter correspond to one model ofheating assembly 12. When thebody 11 is connected to oneheating assembly 12 and onestorage assembly 13, thebody 11 may obtain a first anti-counterfeiting parameter from theheating assembly 12 and obtain a second anti-counterfeiting parameter and the feature parameter from thestorage assembly 13. The controller determines whether the first anti-counterfeiting parameter and the second anti-counterfeiting parameter are valid, whether the first anti-counterfeiting parameter and the second anti-counterfeiting parameter refer to a same model. When the first anti-counterfeiting parameter and the second anti-counterfeiting parameter are determined to be valid, and when the first anti-counterfeiting parameter and the second anti-counterfeiting parameter are determined as referring to the same model, theheating assembly 12 may be heated by taking the feature parameter.
Practically, thebody 11, theheating assembly 12 and thestorage assembly 13 may be sold as a whole, or one or two of themain body 11, theheating assembly 12 and thestorage assembly 13 may be sold in combination. In this way, the user may replace any of the components easily. For example, when the user purchases the device for a first time, the user purchases thebody 11, theheating assembly 12 and thestorage assembly 13 at the same time (correspondence between the model of theheating assembly 12 and the model of thestorage assembly 13 needs to be aware). While using, when theheating assembly 12 is worn out and needs to be replaced, aheating assembly 12 in a model same as the previous model may be purchased only. To be noted that, when the user purchases aheating component 12 with a model different from the previous one, theheating component 12 may not operate properly since the feature parameter stored in thestorage assembly 13 remains unchanged.
In addition, since the model of theheating assembly 12 must correspond to the model indicated by thestorage assembly 13, theheating assembly 12 and thestorage assembly 13 may be sold in combination with each other. For example, when purchasing theheating component 12, an adapted storage assembly 13 (such as a memory card) may be included, ensuring the aerosol generating device to be used normally.
In an embodiment, the memory card may be a SIM card, a secure digital memory card (SD card), a multimedia card (MMC card), a nano memory card (NM card), and the like.

Thebody 11 defines atray receiving cavity 11c and includes acard tray 11d. Thecard tray 11d may be received in thetray receiving cavity 11c. Thecard tray 11d may be configured to hold a memory card. When thecard tray 11d is received in thetray receiving cavity 11c, the memory card is electrically connected to the controller inside thebody 11.
