Description

Technical Field

[0001] The present application relates to the technical field of heating control of heat-without-combustion appliances, and in particular to a heating control method, device, controller and heat-without-combustion appliance. Background Art

[0002] Heat-not-burn appliances are generally equipped with external devices such as infrared sensors or acoustic sensors. When the user inserts the aerosol-generating substrate into the appliance, the appliance can detect the insertion of the object through these external devices and automatically start the heating function. However, when an object that can enter the socket, such as a metal rod or a ceramic rod, is inserted into the appliance, the appliance will still detect the insertion of the object and start heating, which shows that there is a risk of false start. Summary of the invention

[0003] In view of this, the embodiments of the present application provide a heating control method, device, controller and heating non-combustion appliance, which can more accurately identify whether the object inserted into the appliance is an aerosol generating matrix, thereby reducing the risk of misstarting the appliance.

[0008] In the technical solution of the embodiment of the present application, after the heating-not-burning device detects that an object has been inserted, it will emit an infrared light beam to the object. When the infrared light beam hits the object, it will be reflected. After receiving the reflected infrared light signal, the device determines the material type of the object based on the light intensity of the infrared light signal. If it is determined that the material type of the object is an aerosol-generating matrix, heating is started. Since different materials have different absorptivity and reflectivity to infrared light of a specific wavelength, the light intensity of the infrared light signal reflected by the infrared light beam when it hits objects of different materials also varies greatly. Therefore, the above process can more accurately identify the material type of the object inserted into the device based on the light intensity of the reflected infrared light signal, and the heating of the device is only started when it is determined that the material type of the object is an aerosol-generating matrix, thereby reducing the risk of false start-up of the device.

[0041] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures, technologies, etc. are proposed, so as to thoroughly understand the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, the detailed description of well-known systems, devices, circuits and methods is omitted to prevent unnecessary details from hindering the description of the present application. In addition, in the description of the present application specification and the attached claims, the terms "first", "second", "third" etc. are only used to distinguish the description, and cannot be interpreted as indicating or suggesting relative importance.

[0042] Existing heat-not-burn appliances can automatically start heating after detecting an object is inserted, simplifying user operation. However, if an object that can fit into the socket, such as a metal rod or a ceramic rod, is inserted into the appliance, the appliance will still detect the insertion of the object and start heating, which poses a greater risk of false start.

[0043] To address this problem, the embodiments of the present application provide a heating control method, device, controller, and heating non-burning appliance, which can more accurately identify whether an object inserted into the appliance is an aerosol-generating substrate, thereby reducing the risk of mis-starting the appliance. For more specific technical implementation details of the embodiments of the present application, please refer to the various embodiments described below.

[0044] like Figure 1 , which is a schematic diagram of a heating without burning appliance provided in an embodiment of the present application. Figure 1 The heating-not-burning device shown includes a controller, a heating element, and a battery module, wherein the controller is electrically connected to the heating element and the battery module, respectively. The controller can be used to control the temperature of the heating element, and the heating element can be heated up under the control of the controller to bake the aerosol-generating matrix, and the battery module is used to provide electrical energy to the controller and the heating element.

[0045] It should be understood that the executor of each method embodiment of the present application is a controller provided in the heating without burning appliance, for example, it can be a device such as the main control chip of the heating without burning appliance, and the embodiments of the present application do not impose any restrictions on the specific type of the controller.

[0046] See also Figure 2 , shows a heating control method for a heating-not-burning appliance provided in an embodiment of the present application, comprising:

[0047] 201. When an object is detected to be inserted into the heating non-combustion device, an infrared beam is emitted toward the object;

[0048] In the technical solution of the embodiment of the present application, the heating non-combustion device may be provided with two infrared sensor modules, which are respectively recorded as an infrared sensor module and an infrared spectrum module, wherein the infrared sensor module may be installed at the bottom of the receiving channel of the aerosol generating matrix of the device, and the infrared sensor module emits an infrared signal to the object inserted into the device at a set frequency, and the distance between the object and the heat exchange core at the bottom of the receiving channel can be calculated according to the received reflection signal, so as to determine whether the object is inserted into the device and the length of the object inserted into the device. The infrared spectrum module may be installed on the side of the receiving channel of the aerosol generating matrix of the device, and is used to emit an infrared beam to the object inserted into the device, and receive the infrared light signal formed by reflection. After the infrared sensor module detects that the object is inserted into the device for a certain length, the infrared sensor module can be turned off and the infrared spectrum module can be activated, and the infrared spectrum module can be controlled to emit an infrared beam of a certain wavelength to the object according to the set frequency (for example, 10 times / second), for example, an infrared beam of a wavelength of 0.7μm, 5μm, 15μm, etc.

[0049] In one implementation of the embodiment of the present application, emitting an infrared beam to an object includes:

[0050] (1) Detect the insertion distance of the object;

[0051] (2) If the insertion distance reaches the preset standard distance, an infrared beam is emitted toward the object.

[0052] When an object is inserted into the device, the device detects the insertion distance of the object in real time, that is, the distance d between the object and the heat exchange core. Specifically, the infrared sensor module can be used to detect the distance d. In addition, other devices such as ultrasonic sensors or radar devices can also be used to detect the insertion distance d. The embodiment of the present application does not impose any restrictions on the specific distance detection method. If it is detected that the insertion distance d reaches the preset standard distance d 标准 , it means that the object has been inserted into the device for a certain length and meets the infrared beam emission standard. At this time, the infrared spectrum module installed on the side of the accommodating channel is started to emit an infrared beam to the object at the set frequency.

[0053] In one implementation of the embodiment of the present application, emitting an infrared beam to an object includes:

[0054] Infrared beams of different wavelengths are emitted to the object in sequence.

[0055] When controlling the infrared spectrum module to emit an infrared beam to an object, only one wavelength of infrared beam can be emitted to the object at a set frequency. For example, an infrared beam with a wavelength of 5μm can be emitted to the object at a frequency of 10 times / second. Considering that the absorption rate and reflectivity of some different materials to infrared light of a certain wavelength may be similar, in order to improve the accuracy of object material type identification, the infrared spectrum module can be controlled to emit infrared beams of different wavelengths to the object in sequence. For example, infrared beams of different wavelengths such as 0.7μm, 5μm, and 15μm can be emitted to the object in sequence at a frequency of 10 times / second. The more different wavelengths there are, the higher the accuracy of subsequent identification of the object material type, but it will also prolong the time of object material type identification. Therefore, it is generally sufficient to emit more than three different wavelengths of infrared beams.

[0056] 202. After receiving the infrared light signal based on the reflection of the infrared light beam, determine the material type of the object according to the light intensity of the infrared light signal;

[0057] When the infrared light beam emitted by the infrared spectrum module hits the object inserted into the device, it will be reflected to form an infrared light signal, which can be received by the infrared spectrum module. Since different materials have different absorption and reflectivity rates for infrared light of a specific wavelength, the light intensity of the infrared light signal reflected by the infrared light beam when it hits objects of different materials is also quite different. For example, there is a certain difference in the light intensity of the infrared light signal corresponding to the aerosol generating matrix, the light intensity of the infrared light signal corresponding to the metal, and the light intensity of the infrared light signal corresponding to the ceramic. Therefore, based on the light intensity of the emitted infrared light signal, the material type of the object inserted into the device can be identified more accurately. The following describes how to determine the material type of an object based on the light intensity of the infrared light signal.

[0058] In one implementation of the embodiment of the present application, determining the material type of the object according to the light intensity of the infrared light signal includes:

[0059] If the light intensity of the infrared light signal is within a preset light intensity range, it is determined that the material type of the object is an aerosol generating substrate.

[0060] Assuming that only one wavelength of infrared light beam is emitted to the object, after receiving the reflected infrared light signal, it is determined whether the light intensity of the infrared light signal is within the preset light intensity range. If so, it is determined that the material type of the object is an aerosol generating matrix, otherwise it is determined that the material type of the object is not an aerosol generating matrix. Specifically, the device can emit an infrared light beam of this wavelength to the aerosol generating matrix in advance, detect and record the value range of the light intensity of the reflected infrared light signal, thereby constructing a light intensity range [I1, I2], and the light intensity range [I1, I2] can be stored in a storage device such as a register Flash. After obtaining the light intensity I of the infrared light signal corresponding to the current object, if I is within [I1, I2], it is determined that the current object is an aerosol generating matrix, and if I is outside [I1, I2], it is determined that the current object is not an aerosol generating matrix.

[0061] In one implementation of the embodiment of the present application, determining the material type of the object according to the light intensity of the infrared light signal includes:

[0062] (1) generating an infrared spectrum corresponding to the object according to the infrared light signal; wherein the infrared spectrum is used to represent the relationship between the light intensity and wavelength of the infrared light signal;

[0063] (2) Determine the material type of the object based on the light intensity variation characteristics of the infrared spectrum.

[0064] Assuming that multiple groups of infrared light beams with different wavelengths are emitted to an object, the received reflected infrared light signals also include multiple groups. The device can generate an infrared spectrum corresponding to the object after certain signal processing based on the received multiple groups of infrared light signals. The infrared spectrum is used to represent the relationship between the light intensity and wavelength of the infrared light signal, and can clearly reflect the relationship between the light intensity of the infrared light signal and the wavelength. When generating an infrared spectrum according to the infrared light signal, the infrared detector of the infrared spectrum module first receives the reflected infrared light signal and converts the infrared light signal into an electrical signal, which can be converted into a corresponding digital signal after amplification and filtering. Then, the relationship between the light intensity and the wavelength in the digital signal is analyzed to generate the corresponding infrared spectrum. Since different materials have different absorptivity and reflectivity for infrared light of a specific wavelength, the light intensity of the infrared light signal reflected by the infrared light beam when it hits objects of different materials also has large differences. If multiple groups of infrared light signals with different wavelengths are collected, these differences will be reflected as differences in the light intensity change characteristics in the infrared spectrum. Therefore, the material type of the object can be determined based on the light intensity variation characteristics of the infrared spectrum corresponding to the current object. The following describes several specific cases of identifying the material type of an object based on the light intensity variation characteristics.

[0065] In one implementation of the embodiment of the present application, determining the material type of the object according to the light intensity variation characteristics of the infrared spectrum includes:

[0066] If the light intensity of the infrared spectrum is less than the preset light intensity threshold, and the light intensity change characteristic is a trend of first increasing and then decreasing, it is determined that the material type of the object is an aerosol generating matrix.

[0067] Since the reflectivity of the aerosol generating matrix to infrared light is weak but the transmittance is strong, the light intensity of the infrared spectrum corresponding to the aerosol generating matrix is ​​relatively small, for example, the light intensity corresponding to various wavelengths is less than a preset light intensity threshold value A. Moreover, it is found through actual measurement that the light intensity change characteristic of the infrared spectrum corresponding to the aerosol generating matrix has a trend of increasing first and then decreasing, that is, as the wavelength gradually increases, the light intensity first increases and then decreases. The device obtains the infrared spectrum corresponding to the object currently inserted into the device, runs the spectrum analysis function to analyze the infrared spectrum, and if it is found that the light intensity of the infrared spectrum is less than the preset light intensity threshold, and the light intensity change characteristic is a trend of increasing first and then decreasing, it can be determined that the material type of the object is an aerosol generating matrix. On the contrary, if the light intensity of part of the infrared spectrum is greater than the preset light intensity threshold, or the light intensity change characteristic does not have a trend of increasing first and then decreasing, it can be determined that the material type of the object is not an aerosol generating matrix.

[0068] As an example, Figure 3 : is a schematic diagram of an infrared spectrum corresponding to the aerosol generation matrix provided in the embodiment of the present application, wherein the abscissa of the infrared spectrum represents the wavelength and the ordinate represents the light intensity. Figure 3 It can be seen that for the infrared spectrum corresponding to the aerosol generating matrix, the light intensity corresponding to various wavelengths is less than the light intensity threshold A, and the light intensity gradually increases when the wavelength ranges from 0.7μm to 5μm, and the light intensity gradually decreases when the wavelength ranges from 5μm to 15μm, that is, the light intensity change characteristic has a trend of first increasing and then decreasing. This change trend can be used to more accurately identify whether the material type of the object is an aerosol generating matrix.

[0069] In another implementation of the embodiment of the present application, determining the material type of the object according to the light intensity variation characteristics of the infrared spectrum includes:

[0070] If the light intensity of the infrared spectrum is greater than the preset light intensity threshold, and the light intensity change characteristic is a gradually increasing trend, it is determined that the material type of the object is metal.

[0071] Since metals have a strong reflectivity to infrared light and a weak transmittance, the light intensity of the infrared spectrum corresponding to metals is relatively large, for example, the light intensity corresponding to various wavelengths is greater than a preset light intensity threshold value A. Moreover, the metal has a stronger reflectivity to infrared light with a larger wavelength, so the light intensity change characteristic of its infrared spectrum has a gradually increasing trend, that is, as the wavelength gradually increases, the light intensity also gradually increases. The device obtains the infrared spectrum corresponding to the object currently inserted into the device, runs the spectrum analysis function to analyze the infrared spectrum, and if it is found that the light intensity of the infrared spectrum is greater than the preset light intensity threshold, and the light intensity change characteristic is a gradually increasing trend, it can be determined that the material type of the object is metal. On the contrary, if the light intensity of part of the infrared spectrum is less than the preset light intensity threshold, or the light intensity change characteristic is not a gradually increasing trend, it can be determined that the material type of the object is not metal.

[0072] As an example, Figure 4 This is a schematic diagram of the infrared spectrum corresponding to the metal provided in the embodiment of the present application. The horizontal axis of the infrared spectrum represents the wavelength, and the vertical axis represents the light intensity. Figure 4 It can be seen that for the infrared spectrum corresponding to metal, the light intensity corresponding to various wavelengths is greater than the light intensity threshold A, and when the wavelength increases from 0.7μm to 15μm, the light intensity also gradually increases, that is, the light intensity change characteristic is a gradually increasing trend. This change trend can be used to more accurately identify whether the material type of the object is metal.

[0073] In another implementation of the embodiment of the present application, determining the material type of the object according to the light intensity variation characteristics of the infrared spectrum includes:

[0074] If the light intensity of the infrared spectrum is less than the preset light intensity threshold, and the light intensity variation characteristic is a gradually decreasing trend, it is determined that the material type of the object is ceramic.

[0075] The reflectivity and transmittance of ceramics to infrared light are similar to those of aerosol-generating matrices, that is, the reflectivity is weak and the transmittance is strong, so the light intensity of the infrared spectrum corresponding to ceramics is also small, for example, the light intensity corresponding to various wavelengths is less than a preset light intensity threshold A. However, the infrared spectrum corresponding to ceramics has different light intensity variation characteristics compared with the infrared spectrum corresponding to the aerosol-generating matrix. It has been found through actual measurements that the light intensity variation characteristic of the infrared spectrum corresponding to ceramics is a gradually decreasing trend, that is, as the wavelength gradually increases, the light intensity gradually decreases. The device obtains the infrared spectrum corresponding to the object currently inserted into the device, runs the spectrum analysis function to analyze the infrared spectrum, and if it is found that the light intensity of the infrared spectrum is less than the preset light intensity threshold, and the light intensity variation characteristic is a gradually decreasing trend, it can be determined that the material type of the object is ceramic. On the contrary, if the light intensity of part of the infrared spectrum is greater than the preset light intensity threshold, or the light intensity variation characteristic is not a gradually decreasing trend, it can be determined that the material type of the object is not ceramic.

[0076] As an example, Figure 5 This is a schematic diagram of the infrared spectrum corresponding to the ceramic provided in the embodiment of the present application. The abscissa of the infrared spectrum represents the wavelength, and the ordinate represents the light intensity. Figure 5 It can be seen that for the infrared spectrum corresponding to ceramics, the light intensity corresponding to various wavelengths is less than the light intensity threshold A, and when the wavelength increases from 0.7μm to 15μm, the light intensity gradually decreases, that is, the light intensity change characteristic is a gradually decreasing trend. This change trend can be used to more accurately identify whether the material type of the object is ceramic.

[0077] The above is the corresponding content for identifying the material type of an object according to the light intensity change characteristics. In addition to the aerosol generating matrix, metal and ceramic mentioned above, objects of other material types can also be identified in the same way. The embodiments of the present application do not impose any restrictions on the identifiable material types.

[0078] 203. If the material type of the object is an aerosol generating substrate, the heating of the heat-not-burn device is started.

[0079] If it is determined that the material type of the object inserted into the apparatus is an aerosol generating matrix, the heating of the heating non-combustion apparatus is started, and the heating element can be controlled according to the stored standard temperature curve; if it is determined that the material type of the object inserted into the apparatus is not an aerosol generating matrix, such as metal or ceramic, the apparatus is not allowed to heat, thereby avoiding the problem of false start-up.

[0080] In the technical solution of the embodiment of the present application, after the heating-not-burning device detects that an object has been inserted, it will emit an infrared light beam to the object. When the infrared light beam hits the object, it will be reflected. After receiving the reflected infrared light signal, the device determines the material type of the object based on the light intensity of the infrared light signal. If it is determined that the material type of the object is an aerosol-generating matrix, heating is started. Since different materials have different absorptivity and reflectivity to infrared light of a specific wavelength, the light intensity of the infrared light signal reflected by the infrared light beam when it hits objects of different materials also varies greatly. Therefore, the above process can more accurately identify the material type of the object inserted into the device based on the light intensity of the reflected infrared light signal, and the heating of the device is only started when it is determined that the material type of the object is an aerosol-generating matrix, thereby reducing the risk of false start-up of the device.

[0081] To facilitate understanding of the heating control method of the heat-not-burn appliance provided in the embodiment of the present application, an actual application scenario is listed below.

[0082] like Figure 6 FIG. 1 is a schematic diagram of the operation flow of the heating control method for a heating-without-combustion appliance provided in an embodiment of the present application in an actual application scenario. Figure 6 In the application scenario shown, when an object is inserted into the heating-not-burning device, the infrared sensor module is started to detect the insertion distance d of the object; when the insertion distance d reaches the start-up standard, the infrared spectrum module is started to emit three groups of infrared light beams of different wavelengths to the object according to the set frequency, for example, the wavelengths can be 0.7μm, 5μm, and 15μm respectively; the infrared light signal reflected by the object is received by the infrared spectrum module, the infrared light signal is converted into an electrical signal and digitized to obtain a digital signal, and a corresponding infrared spectrum is generated based on the digital signal; the material type of the object is determined by analyzing the light intensity change characteristics of the infrared spectrum; if the material type of the object is an aerosol generating matrix, the device starts heating, and the heating element can be heated and controlled according to the stored standard temperature curve; if the material type of the object is not an aerosol generating matrix (such as metal or ceramic, etc.), the device is not allowed to heat. Through such a setting, it is possible to more accurately identify whether the object inserted into the device is an aerosol generating matrix according to the light intensity change characteristics of the infrared spectrum, and the heating of the device is started only when it is determined that the object is an aerosol generating matrix, thereby reducing the risk of misstarting the device.

[0083] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
