Description

[0001] This application claims priority to Chinese Patent Application No. 202210270221.5, filed on March 18, 2021, entitled "Control Method and Electronic Device for Releasing Fragrance", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of fragrance devices, and more particularly to a method for controlling the release of fragrance and an electronic device. Background Technology

[0003] Fragrance is an important product for regulating users' emotions and enhancing their quality of life, with applications typically including in-car, indoor, and outdoor camping settings. As users' demands for quality of life continue to rise, the demand for fragrance is also increasing. Fragrance manufacturers have increased their production capacity, resulting in a significant increase in the variety and quantity of fragrances on the market. However, the technological development of fragrance release devices (also known as aroma diffusers or fragrance release devices) has been relatively slow. Currently, the fragrance release intensity of these devices is controlled by the user. However, as the fragrance evaporates over a long period, users need to frequently adjust the release intensity of the fragrance device to maintain a suitable concentration in the space, impacting the user experience. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a method and electronic device for controlling the release of fragrance. In this method, the electronic device can automatically adjust the intensity of the released fragrance gas, maintaining the concentration of the fragrance gas in the space at a suitable level, eliminating the need for manual adjustment by the user and effectively improving the user experience.

[0005] In a first aspect, embodiments of this application provide a method for controlling the release of fragrance. The method includes: at a first moment, an electronic device acquires a first concentration value of a fragrance gas released by a fragrance device within a space. Then, the electronic device detects whether the first concentration value meets a preset concentration threshold range. If the electronic device detects that the first concentration value does not meet the preset concentration threshold range, the electronic device can determine the flow rate of the fragrance gas within the space based on the acquired first concentration value. The flow rate indicates the relationship between the injection rate and the loss rate of the fragrance gas within the space. The injection rate indicates the rate at which the fragrance gas is injected into the space, and can also be understood as the rate at which the fragrance device injects the fragrance gas into the space. The loss rate indicates the rate at which the fragrance gas leaves the space. Subsequently, the electronic device can adjust the intensity of the fragrance gas released by the fragrance device based on the acquired flow rate, so that the concentration value of the fragrance gas within the space meets the preset concentration threshold range. Thus, the fragrance release control method in this application monitors the changes in the concentration of fragrance gas in the space and adjusts the intensity of the fragrance gas released by the fragrance device in a timely manner, so that the fragrance gas is maintained within the preset concentration threshold range, thereby achieving dynamic regulation of fragrance release. Without the need for manual operation by the user, the fragrance concentration in the space can be maintained within a suitable range, thereby effectively improving the user experience.

[0006] For example, a fragrance device may include one or more fragrances. The fragrance gas released by the fragrance device into the space is a volatile gas corresponding to one of the multiple fragrances.

[0007] For example, the preset concentration threshold range can be a fixed value. A first concentration value not meeting the preset concentration threshold range may optionally mean that the first concentration value is greater than or less than the threshold. Correspondingly, a first concentration value meeting the preset concentration threshold range may optionally mean that the first concentration value is equal to the threshold.

[0008] For example, the preset concentration threshold range may also include a maximum value and a minimum value, which are different. A first concentration value not meeting the preset concentration threshold range may optionally mean that the first concentration value is greater than the maximum value or less than the minimum value. Correspondingly, a first concentration value meeting the preset concentration threshold may optionally mean that the first concentration value is greater than or equal to the minimum value and less than or equal to the maximum value.

[0009] For example, the relationship between the injection rate and the loss rate can be used to indicate whether the fragrance concentration in a space increases, remains constant, or decreases. Specifically, if the injection rate is greater than the loss rate, it indicates that the fragrance concentration in the space increases. If the injection rate equals the loss rate, it indicates that the fragrance concentration in the space remains constant at a certain level. If the injection rate is less than the loss rate, it indicates that the fragrance concentration in the space decreases.

[0010] For example, the intensity of the fragrance gas released by the fragrance device can be used to represent the rate at which the fragrance device releases fragrance, and the fragrance release rate can also be understood as the fragrance concentration injected into the space per second by the fragrance device.

[0011] For example, the electronic device involved in the embodiments of this application may be integrated into the fragrance device. The electronic device may also be a separate device or apparatus, such as a terminal, wearable device, etc. The electronic device may also be a server in the cloud, which is not limited in this application.

[0012] According to the first aspect, obtaining a first concentration value of a fragrance gas in a space includes: at a first moment, an electronic device acquiring a second concentration value of a target type gas in the space. The target type gas is a component of the fragrance gas. The electronic device can obtain the first concentration value of the fragrance gas by correcting the second concentration value. In this way, the electronic device can obtain the concentration of the corresponding fragrance gas by detecting the concentration of at least one component among the fragrance gas components in the space, thereby providing a simple and convenient method for obtaining fragrance concentration.

[0013] For example, the target type gas is any component in the fragrance gas. It can also be understood as the target type component corresponding to the target type gas being a component in the fragrance.

[0014] For example, the target type ingredient can be a major ingredient in the fragrance, such as an ingredient that accounts for more than 70% of the fragrance ingredients.

[0015] For example, the second concentration value is less than the first concentration value.

[0016] According to the first aspect, or any implementation of the first aspect above, correcting the second concentration value to obtain a first concentration value of the fragrance gas includes: the electronic device acquiring at least one of the fragrance type of the fragrance gas, the temperature value of the space, or the humidity value of the space. For example, the electronic device may acquire the fragrance type, or the electronic device may acquire the fragrance type and the temperature of the space, or the electronic device may acquire the fragrance type and the humidity of the space, or the electronic device may acquire the fragrance type and the temperature and humidity of the space, or the electronic device may acquire the temperature and humidity of the space. Next, in the process of correcting the second concentration value, the electronic device may correct the second concentration value based on a target correction parameter to obtain a first concentration value of the fragrance gas. The target correction parameter is determined based on at least one of the fragrance type, the temperature value, or the humidity value. Thus, the electronic device can determine the correction parameter corresponding to the fragrance under the current environmental conditions, i.e., including at least one of the fragrance type, the temperature value, and the humidity value. The electronic device can correct the concentration of the target type of gas using the correction parameter to obtain the concentration of the fragrance gas. In other words, in this embodiment of the application, the electronic device does not need to detect the concentration of fragrance gas through complex instruments, but instead detects the concentration of the target type of gas and corrects the concentration of the target type of gas to obtain the concentration of fragrance gas, thereby reducing the complexity of the electronic device.

[0017] According to the first aspect, or any implementation thereof, a target correction parameter is determined based on at least one of fragrance type, temperature value, or humidity value, including: the electronic device determining the target correction parameter based on correction parameter correspondence information. The correction parameter correspondence information indicates the correspondence between at least one of fragrance type, temperature value, and humidity value and the correction parameter; the correction parameter correspondence information is pre-acquired. Thus, the electronic device can determine the correction parameter corresponding to at least one of fragrance type, temperature value, or humidity value based on the pre-stored correction parameter correspondence information.

[0018] For example, if the calibration parameter correspondence information stored in the electronic device indicates the correspondence between fragrance types and calibration parameters, the electronic device can obtain the fragrance type and determine the calibration parameter corresponding to the fragrance type based on the calibration parameter correspondence information.

[0019] For example, if the calibration parameter correspondence information stored in the electronic device indicates the correspondence between fragrance type and temperature value and calibration parameters, the electronic device can obtain the fragrance type and temperature value, and determine the calibration parameters corresponding to the fragrance type and temperature value based on the calibration parameter correspondence information.

[0020] For example, if the calibration parameter correspondence information stored in the electronic device indicates the correspondence between fragrance type and humidity value and calibration parameters, the electronic device can obtain the fragrance type and humidity value, and determine the calibration parameters corresponding to the fragrance type and humidity value based on the calibration parameter correspondence information.

[0021] For example, if the calibration parameter correspondence information stored in the electronic device indicates the correspondence between temperature and / or humidity and calibration parameters, the electronic device can obtain the temperature and / or humidity, and determine the calibration parameters corresponding to the temperature and / or humidity values ​​based on the calibration parameter correspondence information.

[0022] For example, if the calibration parameter correspondence information stored in the electronic device indicates the correspondence between the fragrance type, temperature value, and humidity value and the calibration parameters, the electronic device can obtain the fragrance type, temperature value, and humidity value, and determine the calibration parameters corresponding to the fragrance type, temperature value, and humidity value based on the calibration parameter correspondence information.

[0023] For example, the information on the correspondence between correction parameters can be stored in the form of a table or obtained based on an AI model.

[0024] For example, the calibration parameter correspondence information may be obtained by the electronic device before it leaves the factory, and / or obtained from the cloud.

[0025] According to the first aspect, or any implementation of the first aspect above, obtaining the fragrance type of the fragrance gas includes: the electronic device determining the fragrance type in response to a received user operation. The user operation is used to indicate the fragrance type. Alternatively, the electronic device may further obtain the fragrance type of the fragrance gas by acquiring characteristic parameters of the fragrance gas. The characteristic parameters are determined by at least one sensor that collects the fragrance gas. The electronic device then determines the fragrance type based on the characteristic parameters. Thus, the electronic device can obtain the fragrance type corresponding to the fragrance gas currently released by the fragrance device through manual user setting. The electronic device can also identify the fragrance gas using a fragrance gas sensor to obtain the characteristic parameters identified by the fragrance gas sensor. The electronic device can then determine the fragrance type corresponding to the characteristic parameters based on the identification result of the fragrance gas sensor, i.e., the characteristic parameters.

[0026] For example, an electronic device can determine the fragrance type corresponding to a feature parameter as the fragrance type corresponding to the fragrance gas in the space based on stored feature parameter correspondence information. The feature parameter correspondence information is pre-acquired. Optionally, the feature parameter correspondence information can be in tabular form or obtained based on an AI model. Optionally, the feature parameter correspondence information can be obtained before the electronic device leaves the factory, and / or obtained by the electronic device from the cloud.

[0027] According to the first aspect, or any implementation of the first aspect above, the target gas is an alcohol, ketone, or aldehyde gas. Thus, the electronic device can obtain the concentration of the fragrance gas by acquiring the concentration of the main components in the fragrance gas within the space.

[0028] For example, fragrance gases include, but are not limited to, fragrances, as well as alcohols, ketones, or aldehydes.

[0029] According to the first aspect, or any implementation thereof, determining the flow rate of the fragrance gas in a space based on a first concentration value includes: at a second moment, an electronic device acquires a third concentration value of the fragrance gas in the space. The electronic device determines the flow rate of the fragrance gas in the space based on the first concentration value, the third concentration value, and the time difference between the first and second moments. Thus, the electronic device can acquire the flow rate of the fragrance gas based on the concentration change value of the fragrance gas in the space and the time difference between the two concentration acquisition moments.

[0030] For example, electronic devices can also obtain the flow rate of fragrance gas in space through differentiation or other methods.

[0031] According to the first aspect, or any implementation thereof, the intensity of fragrance gas released by the fragrance device is adjusted based on the flow rate, including: when the electronic device detects that a first concentration value is greater than a preset concentration threshold range and the flow rate is greater than a fragrance flow rate threshold, the intensity of fragrance gas released by the fragrance device is reduced. Here, a flow rate greater than the fragrance flow rate threshold indicates that the injection rate of the fragrance gas in the space is greater than the loss rate. In another example, when the electronic device detects that a first concentration value is less than a preset concentration threshold range and the flow rate is less than the fragrance flow rate threshold, the intensity of fragrance gas released by the fragrance device is increased. Here, a flow rate less than the fragrance flow rate threshold indicates that the injection rate of the fragrance gas in the space is less than the loss rate. Thus, the electronic device can determine whether the fragrance gas concentration is increasing, remaining constant, or decreasing based on the relationship between the current fragrance gas concentration value and the preset concentration threshold, using the fragrance flow rate. In one example, if the electronic device detects that the fragrance gas concentration is greater than the preset concentration threshold range and the fragrance gas concentration is increasing, i.e., the fragrance gas flow rate is greater than the flow rate threshold, the intensity of fragrance gas released by the fragrance device can be reduced. In another example, if the electronic device detects that the fragrance gas concentration is greater than a preset threshold range, and the fragrance gas concentration remains constant or decreases (i.e., the fragrance gas flow rate is less than or equal to the flow rate threshold), the fragrance release rate of the fragrance device can be adjusted. In yet another example, if the electronic device detects that the fragrance gas concentration is within the preset threshold range, there is no need to adjust the fragrance release intensity of the fragrance device. In yet another example, if the electronic device detects that the fragrance gas concentration is less than a preset threshold range, and the fragrance gas concentration is decreasing (i.e., the fragrance gas flow rate is less than the flow rate threshold), the fragrance gas release intensity of the fragrance device can be increased. In yet another example, if the electronic device detects that the fragrance gas concentration is less than a preset threshold range, and the fragrance gas concentration remains constant or increases (i.e., the fragrance gas flow rate is greater than or equal to the flow rate threshold), the fragrance release rate of the fragrance device does not need to be adjusted.

[0032] According to the first aspect, or any implementation thereof, the intensity of fragrance gas released by the fragrance device is adjusted based on the flow rate, including: when the electronic device detects that a first concentration value is less than a preset concentration threshold range, the flow rate is less than a fragrance flow rate threshold, and the fragrance device is already at its maximum release intensity, the electronic device displays a prompt message on the interface. The prompt message indicates that the rate of fragrance gas loss within the space is greater than the rate of gas inflow. Here, a flow rate less than the fragrance flow rate threshold means that the rate of fragrance gas inflow within the space is less than the rate of loss. Thus, when the electronic device detects that the fragrance device is already at its maximum fragrance release intensity and the fragrance gas concentration in the space is still decreasing, the electronic device can prompt the user, for example, by prompting the user to close a window, thereby reducing the rate of fragrance gas loss within the space.

[0033] According to the first aspect, or any implementation of the first aspect above, the method further includes: an electronic device instructing the fragrance device to stop releasing fragrance gas. Thus, when the electronic device detects that the fragrance device is already at its maximum fragrance release intensity and the fragrance gas concentration in the space is still decreasing, the electronic device can control the fragrance device to stop releasing fragrance gas to avoid fragrance waste.

[0034] According to the first aspect, or any implementation of the first aspect above, the method further includes: when the electronic device detects that the fragrance device is already at its maximum fragrance release intensity and the fragrance gas concentration in the space is still decreasing, the method further includes: the electronic device pre-acquiring a preset concentration threshold range. The preset concentration threshold range is set by the user or determined according to the fragrance type corresponding to the fragrance gas. In this way, the electronic device can automatically set a suitable concentration range according to the type of fragrance gas, or the electronic device can set a suitable concentration range according to user operation, and monitor the fragrance concentration and flow rate in the space during the fragrance gas release process of the fragrance device to control the intensity of the fragrance gas released by the fragrance device, thereby ensuring that the fragrance gas concentration in the space reaches the preset suitable concentration range.

In this way, the electronic device can obtain the concentration of the corresponding fragrance gas by detecting the concentration of at least one component among the fragrance gas components in the space, thereby providing a simple and convenient method for obtaining fragrance concentration. The electronic device can dynamically adjust the intensity of the fragrance gas released by the fragrance device based on the fragrance gas concentration.

[0036] According to the second aspect, adjusting the intensity of fragrance gas released by the fragrance device includes: the electronic device determining the flow rate of the fragrance gas in the space based on a first concentration value, the flow rate being used to indicate the relationship between the injection rate and the loss rate of the fragrance gas; the injection rate being used to indicate the rate at which the fragrance gas is injected into the space, and the loss rate being used to indicate the rate at which the fragrance gas is lost from the space; and the electronic device adjusting the intensity of the fragrance gas released by the fragrance device based on the flow rate.

In this way, the electronic device can set a knowledge base of different fragrance diffusion modes (i.e., fragrance diffusion intensities) corresponding to different fragrance types. The electronic device can determine the corresponding fragrance diffusion intensity based on the released fragrance type. For example, when the fragrance concentration meets the threshold, the electronic device can repeatedly adjust the fragrance diffusion intensity based on the correspondence between fragrance type and fragrance diffusion intensity, so that the concentration of a specific fragrance type in the space fluctuates.

Alternatively, when the first concentration value is less than the preset concentration threshold and the flow rate is less than the fragrance flow rate threshold, the intensity of the fragrance gas released by the fragrance device is increased; wherein, a flow rate less than the fragrance flow rate threshold indicates that the injection rate of the fragrance gas in the space is less than the loss rate.

[0142] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The scope of protection of this application shall be determined by the claims.

[0143] Figure 1 This is a schematic diagram illustrating the structure of an exemplary fragrance control system. Please refer to... Figure 1 The fragrance control system includes a control device 100 and a fragrance dispersing device 200. The control device 100 includes a detection unit 10 and a processing unit 20. The detection unit 10 includes a gas concentration detection module 11, a gas type identification module 12, and a temperature and humidity detection module 13. The processing unit 20 includes a processing module 21, a transmission module 22, a storage module 23, and an interaction module 24.

[0144] The gas concentration detection module 11 is used to detect the concentration of one or more gases in a space. In this embodiment, the gas concentration detection module 11 is described as an ethanol concentration detection module. The ethanol concentration detection module can be an ethanol concentration sensor used to detect the ethanol concentration in the space. In other embodiments, the gas concentration detection module 11 can also be other gas detection modules to detect other gases. It should be noted that the gas detected by the gas concentration detection module is a component contained in the fragrance. Optionally, the detected gas is a major component of the fragrance (e.g., accounting for more than 70% of the fragrance components), such as alcohols, aldehydes, or ketones, etc., which are not limited in this application. In this embodiment, the gas concentration detection module can be an MQ138 sensor.

[0145] The gas type identification module 12 is used to detect the characteristic values ​​of fragrance gases in the space. Figure 2a The schematic diagram of the gas type identification module 12 is shown as an example. Please refer to... Figure 2aThe gas type identification module 12 includes a sensor array consisting of n gas sensors. Each gas sensor is used to detect characteristic parameters of a specified gas. The characteristic parameter can optionally be the ratio of the resistance value within the sensor to its initial resistance value after the gas sensor detects the specified gas. It should be noted that this embodiment only uses the ratio of the sensor's resistance value to its initial resistance value as an example. In other embodiments, the characteristic parameter can also be the change in resistance value after the sensor comes into contact with the fragrance gas, the maximum value after the resistance change, or the rate of change of resistance value, etc., which is not limited in this application. The characteristic value of the fragrance gas detected by the gas type identification module 12 is the set of gas characteristic parameters obtained by the n gas sensors. The specific detection method will be discussed later. Figures 5-7 The explanation is as follows.

[0146] The temperature and humidity detection module 13 (hereinafter referred to as the temperature and humidity detection module) is used to detect the temperature and humidity values ​​within the space. The temperature and humidity detection module 13 may include a temperature sensor and a humidity sensor. The temperature sensor is used to detect the temperature value within the space. The humidity sensor is used to detect the humidity value within the space. In this embodiment, the temperature and humidity module may be a ZS05 type sensor.

[0147] In the embodiments of this application, all or some of the modules in the detection unit 10 (including the gas concentration detection module 11, the gas type identification module 12, and the temperature and humidity detection module 13) can be integrated on the same chip. Each module can also be an independent device or component, and this application does not impose any limitations on this.

[0148] The processing module 21 is used to detect and process the gas concentration value (also referred to as gas concentration parameter or gas concentration information, etc., which is not limited in this application) input by the gas concentration detection module, the feature value input by the gas type identification module, and the temperature and humidity values ​​input by the temperature and humidity detection module, so as to obtain the fragrance concentration and fragrance flow rate in the space. Based on the fragrance concentration and fragrance flow rate in the space, the processing module 21 can adjust the fragrance dispersing device to an appropriate fragrance release intensity (or fragrance volatilization intensity) so that the fragrance concentration in the space is maintained within a suitable range.

[0149] Storage module 23 is used to store instructions and data. In some instances, the memory is a cache memory. This memory can store instructions or data that the processing module 21 has just used or that are used repeatedly. If the processing module 21 needs to use the instruction or data again, it can directly retrieve it from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0150] The communication module 22 provides an interface for interaction between the modules in the detection unit 10 and the processing module, so as to receive parameters input by the modules in the detection unit 10. In some instances, the communication module 22 may include one or more interfaces. The types of interfaces may be the same or different, and this application does not limit them. It is understood that the interface connection relationships between the modules illustrated in the embodiments of this application are only illustrative and do not constitute a structural limitation on the electronic device 100. In other embodiments of this application, the fragrance control system may also adopt different interface connection methods or a combination of multiple interface connection methods as described in the above embodiments. In the embodiments of this application, the detection unit 10 and the processing unit 20 may be independent or integrated together. Optionally, the communication module may also include a wireless communication module, which can be used to receive or send wireless signal commands.

[0151] The interaction module 24 provides a user interface. The user interface may include fragrance intensity setting options, sliders, or intensity value setting boxes to set the fragrance intensity of the fragrance diffuser. For example, the user interface may offer multiple fragrance diffusion modes (or evaporation modes, release modes, etc., which are not limited in this application) as options. Users can select the corresponding fragrance diffusion mode on the interface to adjust the fragrance intensity of the fragrance diffuser. Different fragrance diffusion modes correspond to different intensities. For example, in this embodiment, the fragrance diffusion modes may include: subtle fragrance diffusion mode, intense fragrance diffusion mode, etc. Different modes may correspond to different airflow, heating levels, compressed air levels, and atomized particle sizes of the fragrance diffuser, which are not limited in this application. Assuming the fragrance intensity corresponding to the subtle fragrance diffusion mode is 1 (e.g., wind speed 1, heating level 1), and the fragrance intensity corresponding to the intense fragrance diffusion mode is 3 (e.g., wind speed 3, heating level 3), then when the fragrance diffuser is in the subtle fragrance diffusion mode, it diffuses fragrance slowly at an intensity of 1; when the fragrance diffuser is in the intense fragrance diffusion mode, it diffuses fragrance rapidly at an intensity of 3. For example, fragrance release intensity can be used to represent the fragrance release rate, which can also be understood as the fragrance concentration injected into the space per second by the fragrance diffuser. Optionally, the interaction module 24 can also be a physical button or other means that provide operation for the user; this application does not limit this.

[0152] It should be noted that the above-mentioned fragrance diffusion modes and corresponding intensities are only illustrative examples. In the embodiments of this application, the fragrance diffusion device can be set with more modes or levels to correspond to different fragrance diffusion intensities, thereby enabling more precise control of the fragrance concentration in the space.

[0153] Optionally, the user interface may also provide a switch option to allow the user to control the opening and closing of the fragrance control system. For example, if the user clicks the switch option to close the fragrance control system, the interaction module responds to the received user operation by sending a closing command to the processing module 21. The processing module 21 can then control all modules in the fragrance control system (including the modules in the control device and the fragrance diffuser) to close.

[0154] Optionally, the user interface may also provide multiple switch options, including switch options corresponding to the fragrance control system and switch options corresponding to the fragrance diffuser. For example, the control device in this embodiment may also integrate other functions, such as displaying the current ambient temperature and humidity. If the user clicks the switch option corresponding to the fragrance diffuser to control the fragrance diffuser to turn off, the interaction module 24 responds to the received user operation and sends an instruction to the processing module 21 to instruct the fragrance diffuser to turn off. The processing module 21 can control the fragrance diffuser to turn off. Optionally, after the fragrance diffuser is turned off, the control device may still be in an operating state or in a standby state; this application does not limit this. For example, if the user clicks the switch option corresponding to the fragrance control system to turn off the fragrance control system, then all modules in the fragrance control system will turn off.

[0155] Optionally, the user interface may also include a fragrance concentration threshold setting option for setting the fragrance concentration threshold within the space. The fragrance concentration threshold can also be understood as the value at which the user expects the fragrance concentration to be maintained within the space. For example, the fragrance concentration threshold setting option may include multiple candidate fragrance concentration thresholds, and the user can select any fragrance concentration threshold. For example, the fragrance concentration threshold option may also include description options corresponding to multiple candidate fragrance concentration thresholds, such as sorted by fragrance concentration from smallest to largest, including: light fragrance option, suitable option, and strong fragrance option. Different options can correspond to different fragrance concentration thresholds, and the specific value can be set according to actual needs; this application does not limit this. Optionally, in this embodiment, the fragrance concentration threshold may also be automatically set by the processing module based on the type of fragrance gas in the current space. The set value may be obtained through multiple measurements or it may be a default value; this application does not limit this.

[0156] For example, the user interface can also be used to display prompts, such as a window closing prompt to remind the user to close the window to prevent the air from circulating too quickly in the space, which would cause the fragrance to evaporate and be wasted.

[0157] In the embodiments of this application, each module in the processing unit 20 can be integrated on the same chip or can be an independent device or component; this application does not impose any limitations.

[0158] The fragrance diffuser 200 is equipped with one or more fragrances and can release the fragrance gas into a space. Optionally, the fragrance diffuser 200 can be a car fragrance device, an indoor fragrance device, etc., and this application does not limit it. Figure 2b This is a schematic diagram illustrating the structure of an exemplary fragrance diffuser. Please refer to... Figure 2b The fragrance dispersing device may include a fragrance dispersing nozzle, a fragrance pool, etc. The fragrance pool is used to hold one or more fragrances. The fragrance pool may include multiple sub-fragrance pools, each holding one fragrance, and the sub-fragrance pools are isolated from each other. The fragrance dispersing nozzle is used to release the fragrance (or, more accurately, release fragrance gas). It should be noted that, typically, if the fragrance pool contains multiple fragrances, the fragrance dispersing nozzle only releases the gas corresponding to one of the multiple fragrances. Optionally, the fragrance pool in the fragrance dispersing device can be replaced, so that after the fragrance in the fragrance pool has evaporated, a new fragrance can be added. The new fragrance can be the same type (or model) as the previous fragrance, or it can be a different type of fragrance; this application does not limit this.

[0159] Please refer to Figure 2b In this embodiment, the control device 100 is integrated into the fragrance diffuser 200 as an example. In another possible implementation, all or part of the modules in the detection unit 10 of the control device 100 can be separate devices, while the processing unit 20 is integrated into the fragrance diffuser 200. In yet another possible implementation, the control device 100 and the fragrance diffuser 200 can be independent devices, communicating via wired or wireless connection. It should be noted that if the control device 100 and the fragrance diffuser 200 are independent devices, the fragrance diffuser 200 also includes a microprocessor and a communication module. The fragrance diffuser 200 can receive control signals sent by the control device 100 through the communication module, and the microprocessor can adjust the corresponding fragrance release intensity based on the received control signals.

[0160] Figure 3a This is a schematic diagram illustrating one application scenario. Please refer to... Figure 3a For example, in a home setting, the fragrance diffuser is located indoors, and its specific structure can be found in [reference needed]. Figure 2b The description in the text will not be repeated here. The fragrance diffuser releases fragrance gas through the diffuser opening, and the fragrance gas can circulate in the indoor space.

[0161] Figure 3b This is an illustrative diagram illustrating another application scenario. Please refer to... Figure 3bFor example, in a vehicle setting, one or more fragrance diffusers and one or more control devices can be installed inside the vehicle. Each control device corresponds to one fragrance diffuser to control that device. Optionally, in other embodiments, multiple fragrance diffusers may correspond to one control device, which can control the fragrance release intensity of each diffuser individually. The number and layout of the control devices and fragrance diffusers are merely illustrative examples; users can set them according to their actual needs, and this application does not impose any limitations. For example... Figure 3b The vehicle is equipped with two fragrance dispersing devices. A control device can be located near the fragrance dispersing devices; that is, as mentioned above, the control device and the fragrance dispersing devices are independent devices. The control device can detect and analyze the fragrance concentration and circulation within the vehicle and send control signals to the fragrance dispersing devices. Based on the control signals, the fragrance dispersing devices can adjust the corresponding fragrance release intensity. Figure 3a and Figure 3b The fragrance control system described in this application is merely an illustrative example and can be applied to other scenarios. This application does not limit its application to such scenarios.

[0162] Combination Figure 1 The control method of the fragrance device in the embodiments of this application will be described in detail below. In this embodiment, the control device and the fragrance dispersing device are integrated into the same device (referred to as the fragrance device in this application) as an example. Exemplarily, the technical solution in the embodiments of this application can be divided into two stages: the manufacturing stage and the usage stage. The manufacturing stage may involve the operator performing factory settings on the fragrance device before it leaves the factory, so that the storage module in the fragrance device saves relevant parameters and instructions. The usage stage may involve the fragrance device detecting and analyzing the fragrance in the space based on the relevant parameters and instructions saved in the manufacturing stage, and adjusting the corresponding fragrance release intensity. The processing procedures of the manufacturing stage and the usage stage will be described in detail below with specific examples.

[0163] Figure 4 This is a schematic diagram illustrating the processing flow during the factory shipment stage. Please refer to... Figure 4 Specifically, it includes:

[0164] S401 offers different fragrance options.

[0165] S402, obtain the feature values ​​corresponding to each fragrance type.

[0166] For example, during the manufacturing process, the operator can place the fragrance device in a sealed space. Furthermore, the operator can set the type of fragrance loaded into the fragrance diffuser within the device. It should be noted that the fragrance type described in this embodiment can correspond to a fragrance brand or a fragrance model; this application does not impose any limitation on this.

[0167] For example, an operator may load fragrance A into the diffuser of a fragrance device. Optionally, fragrance A may be a fragrance model under brand A. The diffuser releases the fragrance gas of fragrance A through the diffuser opening, allowing the fragrance gas of fragrance A to circulate within a sealed space.

[0168] For example, as described above, the gas type identification module may include an array of multiple sensors. This embodiment uses a gas type identification module comprising three gas sensors as an example: MQ4, MQ5, and MQ8 sensors. The sensing material in the MQ type sensors is tin dioxide, which features high sensitivity, fast response time, and low cost.

[0169] Please refer to Figure 5 The fragrance device releases fragrance gas A into the space. Each gas sensor in the gas type identification module can detect fragrance gas A in the space, and the detection time can be set to 1 minute (or can be set according to actual needs; this application does not limit this). The following example illustrates gas sensor 1 as an MQ4 sensor, gas sensor 2 as an MQ5 sensor, and gas sensor 3 as an MQ8 sensor. The models of the gas sensors in this embodiment are merely illustrative examples and are not limited thereto.

[0170] Optionally, each sensor may have different sensitivity (or responsiveness) to different fragrances. The response value of a sensor is the ratio of its resistance to its initial resistance after it comes into contact with the fragrance gas. This response value is the characteristic parameter described in the embodiments of this application.

[0171] Please refer to Figure 6 For example, gas sensors 1-3 identify fragrance gas A. Gas sensor 1 contacts fragrance gas A, and the ratio of its resistance value to the initial resistance value is characteristic parameter 1. Gas sensor 2 contacts fragrance gas A, and the ratio of its resistance value to the initial resistance value is characteristic parameter 2. Gas sensor 3 contacts fragrance gas A, and the ratio of its resistance value to the initial resistance value is characteristic parameter 3. Gas sensors 1-3 output their respective characteristic parameters (including characteristic parameter 1, characteristic parameter 2, and characteristic parameter 3) to the processing module. Optionally, each gas sensor may transmit its characteristic parameters to the processing module through a communication module in the processing unit, which will not be repeated below.

[0172] Optionally, the operator can repeatedly perform the above identification process on fragrance gas A, for example, 100 times, to obtain 100 sets of feature parameters. Each set of feature parameters includes the feature parameters transmitted by gas sensors 1 to 3. The processing module can obtain the feature value corresponding to fragrance A through deep learning. The deep learning method can refer to the technical solutions in existing technical embodiments, and this application is not limited thereto.

[0173] For example, Figure 7 This is a schematic diagram illustrating fragrance characteristic parameters as an example. Please refer to... Figure 7 For example, the processor can obtain characteristic parameter 1 (e.g., 1.6) for gas sensor 1 corresponding to fragrance gas A, characteristic parameter 2 (e.g., 1.4) for gas sensor 2 corresponding to fragrance gas A, and characteristic parameter 3 (e.g., 1.37) for gas sensor 3 corresponding to fragrance gas A. It should be noted that... Figure 7 The fragrance types and characteristic parameters described are merely illustrative examples and are not intended to limit the scope of this application.

[0174] Accordingly, the processing module can determine the feature values ​​corresponding to fragrance A as {feature parameter 1, feature parameter 2, feature parameter 3} based on the acquired feature parameters and the fragrance type set by the operator (i.e., fragrance A).

[0175] The operator can repeatedly execute S401-S402 to allow the processing module to acquire the characteristic values ​​corresponding to different types of fragrances. For example, the operator can load fragrance B into a diffuser in a sealed space; optionally, fragrance B is another fragrance model from brand A. During the release of fragrance B gas by the diffuser, the gas type identification device can identify the fragrance B gas and output the detected characteristic parameters to the processing module. Details not described herein can be found above and will not be repeated here. The processing module can acquire the characteristic parameters of gas sensors 1-3 corresponding to fragrance B gas. For example... Figure 7 In the process, the feature parameters obtained by the processing module are: feature parameter 4 (e.g., 1.53), feature parameter 5 (e.g., 1.25), and feature parameter 6 (e.g., 1.37). Accordingly, the processing module can determine that the feature value corresponding to fragrance B is {feature parameter 4, feature parameter 5, feature parameter 6}.

[0176] For example, the processing module can obtain the feature values ​​{feature parameter 7, feature parameter 8, feature parameter 9} corresponding to fragrance C and the feature values ​​{feature parameter 10, feature parameter 11, feature parameter 12} corresponding to fragrance D according to the above steps.

[0177] S403 allows you to set the fragrance type, fragrance concentration, temperature, and humidity.

[0178] S404, used to detect ethanol concentration.

[0179] S405, based on ethanol concentration and fragrance concentration, obtains calibration parameters.

[0180] For example, an operator can control the fragrance diffuser to release fragrance gas in a sealed space, ensuring that the fragrance concentration in the sealed space reaches a preset detection concentration. Taking fragrance A as an example, the operator can operate the fragrance diffuser containing fragrance A to release fragrance A gas, ensuring that the fragrance A gas concentration in the sealed space reaches a preset detection concentration (this can be set according to actual needs, and this application does not limit it). Furthermore, the operator can set the temperature and humidity within the space. For example, the temperature and humidity within the space can be set to {temperature 1, humidity 1}.

[0181] For example, as described above, this application embodiment uses an ethanol gas sensor as an example to illustrate the gas concentration detection device. That is, the gas concentration detection device can detect the ethanol concentration (also referred to as ethanol gas concentration) in the space.

[0182] For example, the gas concentration detection module can detect the fragrance gas in the space under the current environmental conditions (hereinafter referred to as environmental condition A) and obtain the ethanol concentration in fragrance gas A. The current environmental conditions (i.e., environmental condition A) are: fragrance type is fragrance A, fragrance gas concentration is a preset detection concentration, and {temperature 1, humidity 1}.

[0183] The gas concentration detection module can output the detected ethanol concentration (assuming ethanol concentration 1) to the processing module. The processing module can obtain a correction parameter (e.g., correction parameter 1) based on the ethanol concentration in the space and the concentration of fragrance gas A (i.e., the preset detection concentration). For example, the processing module can obtain the parameter based on formula (1):

[0184] Fragrance A gas concentration = Ethanol concentration * Correction parameter (1)

[0185] In this embodiment, only formula (1) is used as an example for illustration. In other embodiments, the processing module can also calculate the correction parameter based on other formulas. For example, the ethanol concentration plus the correction parameter equals the concentration of fragrance A gas. This application does not limit this.

[0186] The processing module can obtain the correspondence between fragrance type (i.e., fragrance A), temperature and humidity (i.e., {temperature 1, humidity 1}) and correction parameters, as shown in Table 1:

[0187] Table 1

[0188] Fragrance A {Temperature 1, Humidity 1} Correction parameter 1

[0189] For example, the operator can adjust the environmental conditions to obtain the correction parameters for the same type of fragrance (e.g., fragrance A) under the same concentration but different temperature and humidity conditions. For instance, the operator can maintain the concentration of fragrance A in a sealed space at a preset detection concentration, and adjust the temperature and humidity so that the temperature and humidity in the space are {temperature2, humidity2}. The processing module can obtain the ethanol concentration input by the gas concentration detection module as ethanol concentration2. The processing module can obtain the correction parameter as correction parameter2 based on formula (1). Accordingly, the processing module can save the correspondence between fragrance type (fragrance A), temperature and humidity ({temperature2, humidity2}) and correction parameters, as shown in Table 2.

[0190] Table 2

[0191] Fragrance A {Temperature 1, Humidity 1} Correction parameter 1 Fragrance A {Temperature 2, Humidity 2} Correction parameter 2

[0192] Operators can obtain the calibration parameters of fragrance A at the same concentration (i.e., the preset detection concentration) under different environmental conditions (i.e., different temperatures and humidity) in the above manner, and obtain the correspondence between fragrance type, temperature and humidity and calibration parameters. This application will not provide examples for each of these conditions.

[0193] Based on the above method, operators can test different types of fragrances (e.g., fragrance B, fragrance C, and fragrance D) under different environmental conditions (i.e., different temperatures and humidity) to obtain the corresponding calibration parameters and save the correspondence between fragrance type, temperature and humidity, ethanol concentration, and calibration parameters, as shown in Table 3.

[0194] Table 3

[0195]

[0196]

[0197] It should be noted that the values ​​in Table 3 are merely illustrative examples and are not intended to limit the scope of this application. Furthermore, the methods for obtaining correction parameters described in the embodiments of this application are only illustrative examples. In other embodiments, correction parameters can also be obtained through other methods. The purpose is simply to obtain the difference between the actual concentration of the fragrance and the measured ethanol concentration. This allows the fragrance device in the embodiments of this application to obtain the actual fragrance gas concentration during use by correcting the measured ethanol concentration, without needing to use large instruments to measure the fragrance concentration, thus achieving an accurate fragrance gas concentration.

[0198] For example, the operator can store the correspondence between each fragrance type and feature value (also known as feature value correspondence information) obtained by the processing module, as well as the correspondences in Table 3, into the storage module of each fragrance device. It should be noted that this embodiment only uses a table format as an example. In other embodiments, the storage module can store the correspondences in Table 3 (also known as correction parameter correspondence information) and feature value correspondence information in any other format; this application does not limit this. Furthermore, this embodiment only uses the example of the storage module pre-storing the correction parameter correspondence information and feature parameter correspondence information. In other embodiments, the model can be trained based on the above method, and the trained model can be set in the processing unit. In subsequent processes, the processing module can obtain the corresponding fragrance type and correction parameters based on the trained model; this application does not limit this.

[0199] In one possible implementation, during the manufacturing stage, operators can set different diffusion levels for different fragrance types based on experimental data. For example, for woody fragrances (which can also be understood as perfumes with woody notes, such as oud perfume), a slow diffusion mode might be more suitable. For instance, when a user turns on the diffuser, the diffuser slowly injects fragrance gas into the space at a low level (e.g., a subtle diffusion mode), allowing the fragrance concentration to rise gradually, which may better meet the user's needs. Conversely, for lighter perfumes like cologne, a more intense (i.e., rapid) diffusion mode might be more suitable. For example, when a user turns on the diffuser, the diffuser rapidly injects fragrance gas into the space at a high level, causing the fragrance concentration to rise quickly, which may better meet the user's preference for a stronger cologne concentration. The above fragrance types and corresponding diffusion modes are merely illustrative examples and are not intended to limit the scope of this application.

[0200] In another possible implementation, during the manufacturing stage, operators can set different fragrance concentration thresholds for different fragrance types and user groups based on experimental data. For example, operators can collect health data from different user groups, including but not limited to: age, gender, and health status (including whether they have rhinitis). Based on the collected data and user feedback on different fragrance types at different concentrations, operators can obtain the appropriate fragrance concentration thresholds for different types of gases for different user groups. For instance, for fragrance A, the appropriate concentration of fragrance A in a space is concentration A for older users or those with rhinitis. For younger users or those without rhinitis, the appropriate concentration of fragrance A in a space is concentration B. Specific values ​​can be set according to actual needs, and this application does not limit them.

[0201] In one possible implementation, at the factory stage, the processing module can be Figure 1 The processing module shown is illustrated. In this embodiment, the processing module and each detection module may optionally be modules within a testing device. This can be understood as the testing device being used for factory-stage testing and analysis processes, and the operator can save the relevant parameters obtained by the processing module to the storage module of each fragrance device. In other words, the processing module in each fragrance device does not need to possess the functions corresponding to the analysis processes described above.

[0202] In another possible implementation, as the types of fragrances are constantly updated, the detection device can be based on... Figure 4 The process involves obtaining new fragrance-related parameters (including the correspondence between calibration parameters, temperature and humidity parameters, etc.). The detection device can transmit the obtained parameters to the cloud. After each fragrance device is powered on and connected to the network, it can obtain the updated parameters from the cloud. For example, the cloud can push the updated parameters to each fragrance device. Each fragrance device can receive the parameters sent from the cloud through its communication module and save them to its memory. For example, users can also obtain the updated parameters from the cloud through mobile phones or other terminal devices and transmit them to the fragrance devices through Bluetooth or Wi-Fi direct connection, etc., which is not limited in this application.

[0203] Figure 8 This is a schematic diagram illustrating the control method of a fragrance device, which can also be understood as the control method of the fragrance device during its use after leaving the factory. Please refer to... Figure 8 Specifically, it includes:

[0204] S801 sets the fragrance concentration threshold based on the received user operation.

[0205] For example, in the embodiments of this application, Figure 3a To illustrate with an example scenario, the control device and the fragrance diffuser are integrated into the fragrance device, and the fragrance device is placed in the user's home (e.g., in the user's bedroom).

[0206] After the fragrance device powers on in response to a received user command, the user can set the fragrance concentration threshold, i.e., the concentration of fragrance gas the user desires to achieve in the space, through the user interface provided by the processing unit. Optionally, the user can also send a command to the processing module through a terminal (such as a mobile phone, tablet, or wearable device) to set the fragrance concentration threshold; this application does not limit this.

[0207] The processing unit determines the fragrance concentration threshold set by the user based on the received user instructions.

[0208] S802, obtain the current fragrance concentration.

[0209] For example, Figure 9 For an illustrative flowchart of the fragrance concentration acquisition process, please refer to... Figure 9 Specifically, it includes:

[0210] S901 acquires characteristic values, temperature values, and humidity values.

[0211] For example, as described above, the storage module of the fragrance device stores the correspondence between fragrance types, temperature, humidity, and correction parameters, as well as the characteristic values ​​corresponding to the fragrance types. Before obtaining the fragrance concentration, the fragrance device can determine the fragrance type corresponding to the fragrance gas in the space by obtaining the characteristic values. Subsequently, based on the fragrance type, as well as the temperature and humidity values ​​in the space, the corresponding correction values ​​are obtained.

[0212] For details, please refer to Figure 10 The gas concentration detection module in the detection unit can detect the ethanol concentration in the space and output the detected ethanol concentration to the processing module.

[0213] In this embodiment, the gas type identification module includes gas sensor 1 (e.g., MQ4), gas sensor 2 (e.g., MQ5), and gas sensor 3 (e.g., MQ8) as an example. Exemplarily, each gas sensor (including gas sensor 1 to gas sensor 3) in the gas type identification module detects the gas in the space and outputs the detected feature parameters (the concepts are as described above and will not be repeated here) to the processing module. In this example, the feature parameters received by the processor include: feature parameter 1 input from gas sensor 1, feature parameter 2 input from gas sensor 2, and feature parameter 3 input from gas sensor 3. Accordingly, the processing module can determine the feature value corresponding to the fragrance gas type in the space as {feature parameter 1, feature parameter 2, feature parameter 3}.

[0214] Still refer to Figure 10 For example, the temperature sensor in the temperature and humidity detection module can detect the temperature value in the space, and the humidity sensor can detect the humidity value in the space. The temperature and humidity detection module outputs the detected temperature and humidity values ​​to the processing module.

[0215] S902, based on characteristic values, determines the fragrance type.

[0216] For example, the processing module can base its work on the correspondence between fragrance types and feature values ​​stored in the memory (the correspondence can be found in [reference]). Figure 4 The description in the document will not be repeated here. The fragrance type corresponding to the feature value {feature parameter 1, feature parameter 2, feature parameter 3} is determined to be A. In this embodiment, only fragrance A is used as an example for illustration. In other embodiments, it can be other fragrance types. This application does not limit it.

[0217] It should be noted that after the processing module obtains the fragrance type, it can save the obtained fragrance type. When obtaining the fragrance gas concentration again in a subsequent process, it can be processed based on the already obtained fragrance type. That is, there is no need to execute S901-S902 again; it can directly execute S903, thereby speeding up the processing rate. For example, the processing module can execute S901-S902 in the process executed after each restart. That is to say, during the operation of the processing module, the fragrance type released by the fragrance diffuser usually does not change. After the next startup, the fragrance gas type released by the fragrance diffuser may be the same as or different from the previous fragrance gas type, and the processing module can obtain the fragrance type by executing S901-S902.

[0218] It should be further noted that, as mentioned above, the fragrance contained in the fragrance diffuser in this embodiment is replaceable. Users can replace the diffuser itself, or any fragrance in the fragrance pool within the diffuser. Optionally, the diffuser can be configured with a replacement detection program. For example, the diffuser can detect when the container corresponding to the fragrance pool is removed, and send a replacement instruction to the control device to indicate that the fragrance pool has been removed. The control device can execute steps S901 to S902 to identify the type of fragrance released after replacement.

[0219] S903 determines the calibration parameters based on the fragrance type, temperature value, and humidity value.

[0220] For example, as described above, the memory records the correspondence between fragrance type, temperature value, humidity value, and correction parameters. The processing module can determine the corresponding correction parameters based on the acquired fragrance type, temperature value, and humidity value.

[0221] For example, suppose the processing module obtains fragrance type A, and temperature and humidity values ​​{temperature 1, humidity 2}. The processing module can determine the correction parameter corresponding to fragrance A and {temperature 1, humidity 2} as correction parameter 1 by searching the correspondence table stored in the memory (e.g., Table 3).

[0222] It should be noted that the embodiments in this application are all illustrated by the method of obtaining correction parameters based on the correspondence between fragrance type, temperature value, humidity value and correction parameters. In other embodiments, the acquisition of correction parameters may also include other methods. For example, in one example, at the factory stage, the operator can obtain the correspondence between fragrance type and correction parameters according to different scenarios. For example, scenarios may include home scenarios, summer outdoor scenarios, and winter outdoor scenarios. Taking the home scenario as an example, the operator can set the temperature and humidity values ​​in the enclosed space. The set temperature and humidity values ​​are similar to those in a typical user's home and can be set according to specific needs. This application does not limit this setting. Then, the operator can record the correction parameters corresponding to different fragrance types based on the fragrance gas concentration and ethanol gas concentration in the enclosed space, as shown in Table 4.

[0223] Table 4

[0224]

[0225] As shown in Table 4, the calibration parameter correspondence information only includes the correspondence between fragrance type and calibration parameters. In the usage scenario, the user can set the current usage scenario through the processing module, for example, setting the usage scenario to a home scenario. After obtaining the fragrance type, the processing module can obtain the calibration parameters corresponding to the fragrance gas in the space based on the correspondence information corresponding to the home scenario (i.e., Table 4). In this example, the detection unit may not include a temperature and humidity detection module.

[0226] It should be noted that the processing module can also pre-set the humidity and temperature values ​​corresponding to each scene, and detect the current temperature and humidity values ​​after powering on, and determine the corresponding scene based on the current temperature and humidity values.

[0227] It should be further noted that the above embodiments are only illustrated using a home scenario as an example. The processing of other scenarios is similar and will not be repeated here.

[0228] In another example, during the manufacturing process, operators can set a fixed humidity level and obtain the correspondence between different fragrance types, temperatures, and correction parameters at the same humidity, as shown in Table 5:

[0229] Table 5

[0230] Fragrance A Temperature 1 Correction parameter 1 Fragrance A Temperature 2 Correction parameter 2 Fragrance B Temperature 1 Correction parameter 3 Fragrance B Temperature 2 Correction parameter 4 Fragrance C Temperature 1 Correction parameter 5 Fragrance C Temperature 2 Correction parameter 6

[0231] During use, the processing module can obtain the corresponding correction parameters based on the fragrance type and temperature. In this example, the detection unit may not include a humidity detection module.

[0232] In another example, during the manufacturing process, operators can set a fixed temperature and obtain the correspondence between different fragrance types, humidity levels, and calibration parameters at the same temperature, as shown in Table 6:

[0233] Table 6

[0234]

[0235]

[0236] During use, the processing module can obtain the corresponding correction parameters based on the fragrance type and humidity. In this example, the detection unit may not include a temperature detection module.

[0237] In another example, during the manufacturing process, operators can set different temperatures and humidity levels, obtain the correction parameters for each fragrance type under the same temperature and humidity conditions, and take the average value (or other algorithms, which are not limited in this application) to obtain the corresponding correction parameters under different temperature and humidity conditions, as shown in Table 7:

[0238] Table 7

[0239] {Temperature 1, Humidity 1} Correction parameter 1 {Temperature 2, Humidity 2} Correction parameter 2 {Temperature 3, Humidity 3} Correction parameter 3 {Temperature 4, Humidity 4} Correction parameter 4 {Temperature 5, Humidity 5} Correction parameter 5 {Temperature 6, Humidity 6} Correction parameter 6

[0240] During use, the processing module can obtain corresponding correction parameters based on the temperature and humidity within the space. In this example, the detection unit may not include a gas type identification module.

[0241] In other words, in the embodiments of this application, during the manufacturing stage, the calibration parameter correspondence information stored in the storage module can indicate the correspondence between at least one of the fragrance type, humidity, and temperature and the calibration parameter.

[0242] In another possible implementation, the storage module can also save the default values ​​of the calibration parameters. These default values ​​can be obtained by averaging multiple calibration parameters (or by other methods) after obtaining multiple calibration parameters based on different temperatures, humidity and fragrance types during the factory manufacturing stage.

[0243] S904, based on the calibration parameters and ethanol concentration value, determines the fragrance gas concentration.

[0244] For example, the processing module can correct the ethanol concentration value based on formula (1) by obtaining the correction parameters corresponding to the current environmental conditions (i.e., {temperature 1, humidity 2}) of fragrance A in the space, so as to obtain the fragrance gas concentration value (which can also be called the fragrance gas concentration value, which is not limited in this application).

[0245] It should be noted that, in the embodiments of this application, during the process of the processing module repeatedly acquiring the concentration of fragrance gas, the temperature and humidity in the space may change during the release of fragrance gas of a certain type. Accordingly, as the temperature and humidity change, the correction parameters retrieved by the processing module may also be different from the correction parameters acquired previously. This application does not impose any limitations on this.

[0246] S803, detects whether the current fragrance gas concentration is 0.

[0247] For example, when the fragrance device is first turned on, the concentration of fragrance gas in the space can optionally be 0. For instance, Figure 11a For an illustrative diagram showing the concentration of fragrance gases, please refer to... Figure 11a At time t0, the fragrance device powers on in response to the received user operation, and the control device executes steps S801 to S803. In step S803, the fragrance device detects that the fragrance gas concentration is 0. Optionally, the processor can also determine that the fragrance concentration is 0 after receiving a 0 ethanol concentration, without performing the calibration process described above.

[0248] In one example, the processing module detects that the fragrance gas concentration is 0 and executes S804.

[0249] In another example, if the processing module detects that the fragrance gas concentration is not 0 (i.e., greater than 0), it executes S806. For instance, if the user resets the fragrance concentration threshold during the fragrance device's release of fragrance gas, or if the fragrance device restarts, the fragrance device will re-execute S801–S803. When executing S803, previously released fragrance gas may already be present in the space. Accordingly, if the processing module detects that the fragrance gas concentration in the space is greater than 0, it executes S806.

[0250] S804, adjust the fragrance diffuser to the maximum output setting.

[0251] For example, after the processing module detects that the fragrance gas concentration in the space is 0, it can adjust the fragrance diffuser to its maximum setting, that is, adjust the fragrance diffuser to its maximum release intensity, thereby causing the fragrance concentration in the space to quickly rise to the fragrance concentration threshold set by the user. It should be noted that this embodiment uses multiple settings corresponding to different fragrance release intensities as an example for illustration. In other embodiments, the fragrance diffuser may not have settings, for example, it may be adjusted to the maximum fragrance release intensity by directly adjusting the fragrance release intensity.

[0252] It should be noted that, as mentioned above, the user can set the fragrance dispersing mode of the fragrance diffuser. In this example, the processing module adjusts the fragrance diffuser to its maximum setting, optionally by adjusting it to the maximum setting of the current fragrance dispersing mode. Optionally, the processing module can also adjust the fragrance dispersing mode to a mode with a higher release intensity (e.g., a strong mode) and adjust it to the maximum setting of the strong mode; this application does not limit this. To enable those skilled in the art to better understand the technical solutions in the embodiments of this application, this application embodiment only uses a fragrance diffuser with 1 to 5 settings as an example for explanation. The fragrance release intensities corresponding to 1 to 5 settings, from lowest to highest, are: Intensity 1, Intensity 2, Intensity 3, Intensity 4, and Intensity 5, respectively. Correspondingly, the current setting (i.e., the maximum setting) of the fragrance diffuser is setting 5, and the corresponding fragrance release intensity is Intensity 5. This can also be understood as the current fragrance gas release rate of the fragrance diffuser being the maximum achievable value, or the rate at which the fragrance diffuser injects fragrance gas into the space being the maximum value.

[0253] In one possible implementation, as described above, the fragrance diffuser can be pre-set with different fragrance diffusion modes (i.e., diffusion intensities) corresponding to different fragrance types during the manufacturing process. Optionally, in S804, the fragrance diffuser can adjust to the corresponding diffusion mode based on the acquired fragrance type. For example, for fragrance A, the diffusion mode can be adjusted to level 3, allowing the diffuser to slowly inject fragrance A gas into the space. As another example, for fragrance B, the diffusion mode can be adjusted to level 5, allowing the diffuser to quickly inject fragrance B gas into the space. Optionally, in this example, the user can adjust the diffusion level at any time during the operation of the fragrance diffuser via the interactive interface. The fragrance diffuser prioritizes the user-adjusted diffusion level; that is, the diffuser adjusts the diffusion level after receiving the user's adjustment.

[0254] S805, obtain the current fragrance gas concentration.

[0255] For example, during the process of the fragrance diffuser releasing fragrance gas at its maximum setting, the processing module periodically acquires the current fragrance gas concentration in the space to detect whether the fragrance gas concentration in the space has reached the fragrance concentration threshold. Optionally, the period can be 1 minute, which can be set according to actual needs, and this application does not limit it. The specific acquisition method can be referred to the above, and will not be repeated here.

[0256] S806, is the current fragrance gas concentration greater than or equal to the fragrance concentration threshold?

[0257] For example, as described above, the processing module can determine the fragrance concentration threshold based on the received operation. In this step, the processing module compares the obtained fragrance gas concentration in the current space with the fragrance concentration threshold to determine whether the fragrance concentration has reached the maximum concentration threshold at the maximum setting.

[0258] In one possible implementation, as described above, the fragrance diffuser can be pre-set with fragrance concentration thresholds for different fragrance types corresponding to different user groups. The fragrance diffuser can collect users' health data and set corresponding fragrance concentration thresholds based on the acquired health data and fragrance type. Optionally, the user's health data collected by the fragrance diffuser can be set by the user through an interactive interface. For example, the interactive interface includes a health data input box where the user can input corresponding data, including but not limited to age, whether they have rhinitis, gender, etc. Optionally, the fragrance diffuser can also collect user health data through other devices with the same account. For example, the fragrance diffuser can obtain health data collected by wearable devices of users with the same account when connected to the internet. The method of obtaining health data is only an illustrative example and is not limited in this application. It can be understood that in this example, the fragrance diffuser may not execute S801, that is, in S802, after the fragrance diffuser obtains the fragrance type, it can set the corresponding fragrance concentration threshold based on the fragrance type and the user's health data. For example, the fragrance diffuser can display the currently set fragrance concentration threshold in the interactive interface. It should be noted that the embodiments in this application only illustrate the example of setting corresponding fragrance concentration thresholds for different user groups corresponding to different fragrance types. In other embodiments, the fragrance diffuser may also set corresponding fragrance concentration thresholds based solely on the fragrance type. Alternatively, the fragrance diffuser may also set corresponding fragrance concentration thresholds based on the user group. This application does not impose any limitations. Optionally, the user can adjust the fragrance concentration threshold at any time during the operation of the fragrance diffuser through the interactive interface. It should be noted that the fragrance diffuser prioritizes the fragrance concentration threshold set by the user. That is, if the fragrance diffuser determines that the fragrance concentration threshold corresponding to the current fragrance A is X, and the user adjusts the fragrance concentration threshold through the interactive interface, the fragrance diffuser will adjust according to the fragrance concentration threshold adjusted by the user in all subsequent processes. Optionally, the interactive interface may also provide a restore default value option. For example, after the user adjusts the fragrance concentration threshold, they can click the restore default value option, and the fragrance diffuser will respond to the received user operation by adjusting the fragrance concentration threshold to the default value, which is the fragrance concentration threshold corresponding to the fragrance type.

[0259] In one example, if the fragrance gas concentration is less than the fragrance concentration threshold—that is, the gas concentration in the space has not yet reached the fragrance concentration threshold—the processing module executes S807. For an example, please refer to [link / reference needed]. Figure 11a At time t1, the fragrance gas concentration obtained by the processing module is fragrance gas concentration 1. The time interval between time t1 and time t0 can be the cycle length of the processing module (e.g., 1 minute). For example, if the processing module detects that fragrance gas concentration 1 is less than the fragrance concentration threshold, it executes S807.

[0260] In another example, if the fragrance gas concentration is greater than or equal to the fragrance concentration threshold, that is, the fragrance gas concentration in the space has reached the fragrance concentration threshold, the processing module executes S809.

[0261] It should be noted that in this embodiment, the fragrance concentration threshold can be a single value or a threshold range, and this application does not limit this. Optionally, after the user sets the fragrance concentration threshold, the processing module can determine the corresponding fragrance concentration threshold range based on the user-set fragrance concentration threshold. For example, after the user sets the fragrance concentration threshold, the processing module can add or subtract a preset value (e.g., 200 pm) to the user-set fragrance concentration threshold to obtain the fragrance concentration threshold range. Accordingly, if the processing module detects that the fragrance gas concentration range in the space meets the fragrance concentration threshold, that is, is equal to the fragrance concentration threshold, or is within the fragrance concentration threshold range, then S807 can be executed. If the processing module detects that the fragrance gas concentration in the space is less than or greater than the fragrance concentration threshold, or the processing module detects that the fragrance gas concentration threshold in the space is greater than the maximum value of the fragrance concentration threshold range, or less than the minimum value of the fragrance concentration threshold range, then S809 is executed.

[0262] S807 detects whether the fragrance concentration has increased.

[0263] For example, when the processing module detects that the fragrance gas concentration in the space is greater than or equal to a fragrance concentration threshold, or that the fragrance gas concentration is greater than or equal to the minimum value of the fragrance concentration threshold range, the processing module obtains the fragrance gas concentration flow rate, which is referred to as the fragrance flow rate in this embodiment. Based on the fragrance gas concentration flow rate, the processing module can determine whether the fragrance gas concentration increases, remains unchanged (or fluctuates slightly), or decreases.

[0264] For example, the fragrance flow rate can also be understood as the rate of change of fragrance gas concentration. The processing module can obtain the fragrance flow rate v through formula (2):

[0265]

[0266] Where △S represents the change in fragrance gas concentration, that is, the difference between the fragrance gas concentration obtained by the processing module this time and the fragrance gas concentration threshold obtained last time. For example, referring to... Figure 11a As described above, in this embodiment, the processor can periodically acquire the concentration threshold, and the interval between time t1 and time t0 is the duration of the interval (e.g., 1 minute). Accordingly, △S is the difference between the fragrance gas concentration value at time t1 and the fragrance gas concentration value at time t0.

[0267] Referring again to formula (2), where t is the time difference between the time corresponding to the current acquisition of fragrance gas concentration and the time corresponding to the previous acquisition of fragrance gas concentration. Figure 11a For example, t is the time difference between t1 and t0. Optionally, it can be the period length, such as 1 minute (i.e., 60 seconds).

[0268] It should be noted that the formula used to calculate the fragrance flow rate in the embodiments of this application is only an illustrative example. In other embodiments, the processing module can also obtain the fragrance flow rate at the current moment in other ways. For example, the processing module can differentiate the fragrance gas concentration at the current moment to obtain the fragrance flow rate. This application does not limit this.

[0269] It should be noted that the fragrance flow rate obtained by the processing module can also be understood as the slope of the fragrance concentration at the current moment. For example, referring to... Figure 11a Taking time t1 as an example, the fragrance flow rate obtained by the processing module is the slope at time t1.

[0270] The processing module can determine whether the fragrance gas concentration in the space is increasing, remaining constant, or decreasing based on the fragrance flow rate, which can also be understood as the slope of the fragrance gas concentration at the current moment.

[0271] For example, if the concentration of fragrance gas increases, the slope at the current moment is positive, which means that the fragrance flow rate is greater than the fragrance flow rate threshold. This can also be understood as the injection rate of fragrance gas into the space being greater than the loss rate.

[0272] For example, if the concentration of fragrance gas decreases, the slope at the current moment is negative, which means that the fragrance flow rate is less than the fragrance flow rate threshold. This can also be understood as the injection rate of fragrance gas into the space being less than the loss rate.

[0273] For example, if the fragrance gas concentration remains complex, then the slope at the current moment is 0, and the fragrance flow rate is equal to the fragrance flow rate threshold (or it can fluctuate slightly up and down). That is, the fragrance gas concentration remains at a constant value (or fluctuates slightly up and down). It can also be understood that the injection rate and loss rate of fragrance gas in the space are equal.

[0274] It should be noted that, as mentioned above, the processing module obtains the rate of change of fragrance gas concentration between the current time and the previous time. Accordingly, the increase and decrease mentioned in this application embodiment can be selected as the fragrance gas concentration at the current time increasing the same (i.e., remaining unchanged) or decreasing compared to the fragrance gas concentration at the previous time (i.e., the time when the fragrance gas concentration was last obtained).

[0275] For example, the processing module can set a fragrance flow rate threshold, which is used to indicate whether the increase in fragrance gas concentration meets expectations. For example, if the processing module detects that the fragrance flow rate is greater than or equal to the fragrance flow rate threshold, then S805 is executed repeatedly.

[0276] In one possible implementation, the fragrance flow rate threshold can be 0. In one example, when the fragrance flow rate is greater than the fragrance flow rate threshold, the processing module can determine that the fragrance gas concentration has increased. That is, a positive fragrance flow rate means that the fragrance injection rate in the space is greater than the fragrance loss rate, which can also be understood as the slope at the current moment being positive.

[0277] For example, refer to Figure 11a Taking time t1 as an example, the fragrance gas concentration at time t1 is greater than that at time t0. The processing module obtains that the fragrance flow rate at time t1 is greater than 0, that is, the slope at time t1 is positive. The processing module determines that the fragrance concentration at time t1 is in an upward state, so S805 can be executed repeatedly, that is, the fragrance gas concentration can continue to be obtained to detect the change in fragrance gas concentration.

[0278] In another example, if the fragrance flow rate is less than the fragrance flow rate threshold (i.e., less than 0), the processing module can determine that the fragrance gas concentration has decreased. In other words, a negative fragrance flow rate means that the fragrance injection rate within the space is less than the fragrance loss rate; this can also be understood as the slope at the current moment being negative. For an example, please refer to... Figure 11b At time t2, the processing module detects that the detection period has ended; that is, the interval between time t2 and time t1 is the period duration. It should be noted that at time t1, the processing module detects that the fragrance flow rate is greater than the fragrance flow rate threshold (i.e., greater than 0), and the processing module re-executes S805. That is, at time t2, the processing module re-acquires the fragrance gas concentration in the space at the current time and obtains the corresponding fragrance flow rate based on the fragrance gas concentration. For example... Figure 11b As shown, before time t2, the concentration of fragrance gas in the space begins to decrease. For example, this could be due to the user opening a window, causing the rate of fragrance loss to exceed the rate of fragrance injection. It should be noted that the scenarios causing fragrance loss described in this embodiment are merely illustrative examples and are not intended to limit the scope of the application. (Referring to...) Figure 11b For example, if the processing module detects that the fragrance flow rate is less than the fragrance flow rate threshold (i.e., less than 0), or the slope at time t2 is negative, the processing module can determine that the fragrance gas concentration at time t2 is lower than that at the previous time (e.g., time t1) and execute S808.

[0279] For example, if the fragrance flow rate equals the fragrance flow rate threshold, the processing module can determine that the current fragrance gas concentration is the same as the fragrance gas concentration obtained at the previous moment, that is, the fragrance gas concentration slope is 0, and the fragrance gas injection rate and loss rate are equal (or similar). For example, if the fragrance device is already at its maximum release intensity, and the fragrance gas concentration remains at a certain concentration (which is less than the fragrance concentration threshold) and does not increase, it will also lead to fragrance evaporation and waste, and the processing module can execute S808.

[0280] In another possible implementation, the fragrance flow rate threshold can be any value greater than 0, which can be set according to actual needs, and this application does not limit it. A fragrance gas concentration greater than or equal to the fragrance flow rate threshold can also be understood as follows: if the slope at the current moment is positive and greater than or equal to the fragrance flow rate threshold, then the increase in fragrance gas concentration is determined to meet expectations. Conversely, if the fragrance flow rate is less than the fragrance flow rate threshold, then the increase in fragrance gas concentration is determined to not meet expectations.

[0281] It should be noted that the condition of fragrance flow rate being less than the fragrance flow rate threshold includes both a fragrance flow rate greater than 0 and less than the fragrance flow rate threshold, and a fragrance flow rate less than 0. For example, if the fragrance flow rate is less than 0, it means that the fragrance gas concentration has decreased; a detailed description can be found in [reference needed]. Figure 11b This will not be elaborated further here. For example, if the fragrance flow rate is greater than 0 and less than the fragrance flow rate threshold, it can be understood that although the fragrance concentration is increasing, the increase is small, which can be understood as a small difference between the fragrance gas loss rate and the injection rate within the space. In this embodiment, the fragrance dispersing device releases fragrance gas at its maximum release intensity, but the fragrance gas concentration increases at a small rate within the space, i.e., when the fragrance flow rate is greater than 0 and less than the fragrance flow rate threshold, the fragrance concentration within the space may take a long time to reach the fragrance concentration threshold. Accordingly, the processing module can execute S808 to avoid fragrance evaporation and waste.

[0282] For example, please refer to Figure 11cAt time t1, the processing module can obtain the fragrance flow rate at time t1, i.e., the slope at time t1. Assuming the processing module detects that the fragrance flow rate is greater than 0 and less than the fragrance flow rate threshold, the processing module can determine that the fragrance gas concentration is not increasing, or it can be understood as the fragrance gas concentration increasing but the rate of increase does not meet expectations. That is to say, the fragrance gas concentration in the space increases relatively slowly from time t0 to time t1. However, in the current scenario, the fragrance dispersing device is already at its maximum fragrance release intensity, but the fragrance gas concentration increase rate (i.e., fragrance flow rate) is still less than the fragrance flow rate threshold. The reason for this phenomenon may be that the fragrance loss rate in the space is too high (but its rate is still less than the fragrance gas injection rate). For example, the user's bedroom may have a window open, and the window is wide open, causing the fragrance gas to flow out of the window. In this case, the processing module executes S808.

[0283] In another possible implementation, the processing module can set a first fragrance flow rate threshold and a second fragrance flow rate threshold. The first fragrance flow rate threshold is greater than the second fragrance flow rate threshold, and the first fragrance flow rate threshold is greater than 0. For example, if the fragrance flow rate is greater than the first fragrance flow rate threshold, the processing module can determine that the fragrance gas concentration is increasing, i.e., the injection rate of the fragrance gas in the space is greater than the loss rate, and then execute S808. For example, if the fragrance flow rate is less than the first fragrance flow rate threshold but greater than the second fragrance flow rate threshold, the processing module can determine that the fragrance gas concentration remains constant (or fluctuates slightly, the fluctuation range depending on the difference between the first and second fragrance flow rate thresholds), and the processing module can execute S808 or re-execute S805, depending on actual needs. For example, if the fragrance flow rate is less than the second fragrance flow rate threshold, the processing module can determine that the fragrance gas concentration is decreasing, i.e., the injection rate of the fragrance gas in the space is less than the loss rate.

[0284] S808, turn off the fragrance diffuser.

[0285] For example, as described above, when the processing module detects that the fragrance flow rate is less than the fragrance flow rate threshold—that is, when the fragrance diffuser is releasing fragrance at its maximum release rate but the rate of increase in fragrance gas concentration in the space is small, or when the fragrance gas concentration is decreasing—the processing module can send an instruction to the fragrance diffuser to stop dispersing fragrance. This instruction can be understood as follows: when the fragrance diffuser is dispersing fragrance at its maximum release intensity, if the user's bedroom window is wide open, the fragrance gas loss rate is too high, resulting in fragrance evaporation and waste. The processing module controls the fragrance diffuser to stop dispersing fragrance to conserve the diffuser's power and avoid fragrance evaporation waste.

[0286] Optionally, the processing module can display a prompt message in the user interface, indicating that the fragrance loss rate in the current space is high. For example, the prompt message could suggest that the user close the windows to reduce the fragrance loss rate in the space.

[0287] In one possible implementation, the processing module may simply display a prompt message in the user interface without turning off the fragrance dispersing device; this application does not impose any limitations on this.

[0288] Optionally, after the fragrance diffuser is turned off, the fragrance device (i.e., the control device) remains in operation (or standby mode), and the user can continue to release fragrance gas by using the power-on option of the fragrance device or by controlling the fragrance diffuser to continue releasing fragrance gas through a terminal or other device.

[0289] S809, turn off the fragrance diffuser.

[0290] For example, after the processing module detects that the concentration of fragrance gas in the space has reached the fragrance concentration threshold, it can briefly shut down the fragrance diffuser to obtain the current fragrance flow rate, i.e., execute S810. It should be noted that shutting down the fragrance diffuser in this step can optionally mean controlling the fragrance diffuser to stop releasing fragrance gas, while the fragrance device remains in operation.

[0291] S810, obtain the current fragrance flow rate.

[0292] For example, the processing module shuts down the fragrance diffuser; that is, after controlling the fragrance diffuser to stop releasing fragrance gas, the processing module obtains the current fragrance flow rate. The method of obtaining this information is described above and will not be repeated here.

[0293] S811 adjusts the fragrance diffuser setting according to the fragrance flow rate.

[0294] For example, the fragrance flow rate obtained by the processing module in S810 can also be called the instantaneous flow rate. It can also be understood as the processor temporarily shutting down the fragrance dispersing device to obtain the instantaneous flow rate of the fragrance gas in the space. Based on this rate, the processing module can determine the current fragrance injection and loss situation in the room, restart the fragrance dispersing device, and adjust the fragrance dispersing device to an appropriate level.

[0295] As mentioned above, different settings of the fragrance diffuser correspond to different fragrance release intensities (i.e., different fragrance release rates). If the diffuser is always at its maximum setting, the fragrance gas concentration in the space may be too high, affecting the user experience. Conversely, if the diffuser is turned off, the fragrance gas concentration in the space may drop rapidly, resulting in a large difference between the fragrance gas concentration and the fragrance concentration threshold within a short period. In this embodiment, after the diffuser is turned off, the processing module adjusts the diffuser to an appropriate setting based on the fragrance flow rate. During the operation of the diffuser, steps S810 to S811 are executed periodically to dynamically adjust the fragrance release intensity of the diffuser according to the real-time flow rate of the fragrance gas in the space.

[0296] For example, please refer to Figure 11a At time t2, the processing module detects that the fragrance gas concentration equals the fragrance concentration threshold and shuts off the fragrance dispersing device. Assuming the user's room window is currently open, but at a small angle, it can be understood that the fragrance gas concentration in the space can escape through the open window, but the rate of escape is small. For example, still referring to... Figure 11a At time t3 (where the interval between time t3 and time t2 is less than or equal to the detection period of the processing module, which is not limited in this application), the processing module obtains the fragrance flow rate as fragrance flow rate a (i.e., the slope at time t3). For example, if the processing module detects that the fragrance flow rate a at time t3 is less than the fragrance flow rate threshold (the concept can be referred to above), the processing module can determine that the fragrance gas concentration at time t3 is lower than the fragrance gas concentration at the previous time (e.g., time t2). In other words, the rate of fragrance gas loss in the space is greater than the rate of fragrance injection. It should be noted that the fragrance dispersing device is currently in a stopped state; therefore, the fragrance gas injection rate in the space is 0. The processing module can detect the relationship between the fragrance flow rate a and the fragrance release rate corresponding to each setting. For example, if the fragrance flow rate a is between the intensity 2 corresponding to setting 2 and the intensity 3 corresponding to setting 3, the processing module starts the fragrance dispersing device and adjusts it to setting 2 or setting 3.

[0297] To illustrate further, suppose the user's room is closed and in a relatively sealed state. In this scenario, after the fragrance diffuser is turned off, the fragrance flow rate in the space is very low, or close to zero. The processing module obtains the fragrance flow rate as fragrance flow rate b. The processing module detects that the fragrance flow rate b is less than the intensity 1 corresponding to level 1. Optionally, the processing module can activate the fragrance diffuser and adjust it to level 1, that is, set its fragrance release intensity to intensity 1. Optionally, the processing module can also not activate the fragrance diffuser and periodically detect the fragrance gas concentration in the space. If the processing module detects that the fragrance gas concentration drops below the fragrance concentration threshold, and the difference between the fragrance gas concentration and the fragrance concentration threshold is greater than or equal to a preset difference (which can be set according to actual needs, and this application does not limit it), that is, when the fragrance gas concentration in the space drops to a certain value, the processing module can execute S810, that is, obtain the fragrance flow rate and adjust the level of the fragrance diffuser based on the fragrance flow rate.

[0298] In one possible implementation, as described above, the fragrance diffuser at S804 may be adjusting its diffuser setting according to different fragrance types; that is, the diffuser may not be operating at its maximum setting. In this case, the working process of the fragrance diffuser remains consistent with that described in S811, i.e., adjusting the diffuser setting according to the fragrance flow rate. In some embodiments, if the fragrance flow rate obtained at the currently operating setting of the fragrance diffuser corresponds to the fragrance diffusion rate at the current setting, then there is no need to adjust the diffuser setting; that is, the fragrance diffuser remains at its current setting.

[0299] Figure 12 For an illustrative flowchart of the fragrance release control method, please refer to... Figure 12 Specifically, it includes:

[0300] S1201, obtain the current fragrance gas concentration and fragrance flow rate.

[0301] For specific acquisition methods, please refer to the above text, which will not be repeated here.

[0302] S1202, detect whether the current fragrance gas concentration is greater than or equal to the fragrance concentration threshold.

[0303] In one example, if the processing module detects that the current fragrance gas concentration is greater than or equal to the fragrance concentration threshold, or that the fragrance gas concentration is greater than the maximum value in the fragrance concentration threshold range (which can be set according to actual needs, and this application does not limit it), then S1203 is executed.

[0304] In another example, if the processing module detects that the current fragrance gas concentration is less than or equal to the fragrance concentration threshold, or that the fragrance gas concentration is less than the minimum value in the fragrance concentration threshold range, then S1205 is executed.

[0305] In this embodiment, the fragrance concentration threshold can be preset by the user, such as in S801 where the user sets it through the interactive interface. In one possible implementation, the fragrance concentration threshold can also be a default value, as described above, where the fragrance diffuser can set corresponding fragrance concentration thresholds based on different fragrance types and / or user groups (i.e., user data). In another possible implementation, the fragrance concentration threshold can be the fragrance concentration threshold adjusted by the user from the default threshold. In yet another possible implementation, the fragrance diffuser can also be preset with different increment values ​​for fragrance concentration thresholds for different fragrance types and user groups. For example, if a user stays in a space filled with fragrance for a long time, they may experience olfactory fatigue. For instance, if the fragrance diffuser continuously diffuses fragrance and the user remains in the space for 10 minutes, the user may become insensitive to the fragrance. In this case, the fragrance diffuser can increase the fragrance concentration threshold in the space to adjust the overall concentration of the fragrance gas in the space. For example, for fragrance A, the suitable concentration of fragrance A in the space for older users or those with rhinitis is concentration A (e.g., 80 ppm), and the fragrance concentration threshold can increase by 5% every 10 minutes. For younger users or those without rhinitis, the suitable concentration of fragrance A in the space is concentration B (e.g., 120 ppm), and the fragrance concentration threshold can increase by 10% every 10 minutes. Specific values ​​can be set according to actual needs and are not limited in this application. That is, in this embodiment, the fragrance diffuser can dynamically adjust the fragrance concentration threshold based on the fragrance type, user group, and the diffuser's diffusion duration to meet user needs. It should be noted that in other embodiments, the fragrance diffuser can also adjust the fragrance concentration threshold based on any one or more of the following parameters: fragrance type, user group, and diffuser's diffusion duration. For example, the fragrance diffuser can adjust the fragrance concentration threshold based on both the fragrance type and diffusion duration. For example, the fragrance concentration threshold increase for fragrance A can be preset to increase by 10% every 10 minutes, while the fragrance concentration threshold increase for fragrance B can be preset to increase by 15% every 10 minutes. Furthermore, the fragrance device can adjust the fragrance concentration threshold based on the user group and the duration of fragrance dissipation. For instance, for any fragrance type, the increase rate can be preset to 10% every 10 minutes for younger users, and 5% every 10 minutes for older users.

[0306] Optionally, the fragrance diffuser can also be set with an upper limit for the increase of the fragrance concentration threshold. Optionally, the fragrance diffuser can set different upper limits for the increase of the fragrance concentration threshold for different fragrance types and user groups. For example, for fragrance A, for younger users or those without rhinitis, the increase in the fragrance concentration threshold of fragrance A should not exceed 40%. For older users or those with rhinitis, the increase in the fragrance concentration threshold of fragrance A should not exceed 30%. Optionally, the upper limit for the increase of the fragrance concentration threshold can also be a fixed value, such as 300 ppm. Of course, the fixed upper limit value can be the same or different for different user groups corresponding to different fragrance types. The specific value can be set according to actual needs, and this application does not limit it. That is to say, when the fragrance diffuser performs… Figure 12 During the process, the fragrance concentration threshold can be dynamically adjusted based on the type of fragrance and the user's health data (the method for obtaining user health data can be found above and will not be repeated here). Furthermore, the setting of the fragrance diffuser can be adaptively adjusted based on the adjusted fragrance concentration threshold, the fragrance concentration in the space, and the fragrance flow rate.

[0307] S1203, detects whether the concentration of fragrance gas increases.

[0308] For example, when the processing module detects that the fragrance gas concentration in the space is greater than or equal to a fragrance concentration threshold, or that the fragrance gas concentration is greater than the fragrance concentration threshold range, the processing module can obtain the fragrance flow rate and, based on the fragrance flow rate, detect whether the fragrance gas concentration has increased. For parts not described, please refer to the relevant description in S807, which will not be repeated here.

[0309] In one example, if the processing module detects that the fragrance flow rate is greater than or equal to the fragrance flow rate threshold, it can determine that the fragrance gas concentration has increased. That is, if the fragrance gas concentration has exceeded the appropriate concentration and the fragrance gas concentration is still rising, S1204 can be executed, that is, by reducing the fragrance release intensity of the fragrance dispersing device, the fragrance gas concentration in the space is reduced to be equal to or close to the fragrance concentration threshold.

[0310] In another example, if the processing module detects that the fragrance flow rate is less than or equal to the fragrance flow rate threshold (or fluctuates slightly around the fragrance flow rate threshold), it can determine that the fragrance gas concentration has decreased. That is, if the fragrance gas concentration exceeds the appropriate concentration, but the fragrance gas concentration is already decreasing, the processing module may not adjust the setting of the fragrance diffuser, i.e., it may repeat step 1201.

[0311] For example, please refer to Figure 13For example, at time t4, the processing module detects that the fragrance gas concentration is greater than or equal to the fragrance concentration threshold, and the processing module obtains the fragrance flow rate. The processing module detects that the fragrance flow rate is greater than the fragrance flow rate threshold, meaning the slope at time t4 is positive. This indicates that the fragrance gas concentration in the space has reached or exceeded the fragrance concentration threshold, and the fragrance gas concentration continues to rise. Alternatively, it can be understood that the fragrance gas concentration has reached or exceeded the fragrance concentration threshold, and the injection rate of the fragrance gas in the space is still greater than the loss rate. In this case, the processing module can reduce the fragrance release intensity of the fragrance diffuser. For example, if the processing module detects that the current fragrance flow rate is between the fragrance release rate of level 1 and level 2, the processing module can adjust the fragrance diffuser to level 1 or level 2. Of course, the processing module can also turn off the fragrance diffuser to reduce the fragrance release concentration of the fragrance diffuser; this application does not limit this.

[0312] To illustrate further, refer to... Figure 13 For example, after the fragrance diffuser lowers its output level (e.g., currently at level 2), the concentration of fragrance gas in the space decreases. At time t5 (the interval between time t4 and time t5 is the cycle length), the processing module re-executes S1201, that is, obtains the fragrance gas concentration and fragrance flow rate. If the processing module detects that the current fragrance gas concentration is greater than or equal to the fragrance concentration threshold, and the fragrance flow rate is less than the fragrance flow rate threshold, that is, after the release intensity of the fragrance diffuser is reduced, the fragrance gas concentration in the space decreases accordingly, then the processing module repeats S1201.

[0313] It should be noted that descriptions regarding fragrance flow rate and fragrance flow rate threshold can be found in [reference needed]. Figure 8 The relevant content will not be repeated here.

[0314] In one possible implementation, if the current fragrance gas concentration detected by the fragrance diffuser is within or equal to the fragrance concentration threshold, in one example, the fragrance diffuser can dynamically fine-tune its output level according to the fragrance type. For example, for fragrance A, if the fragrance diffuser detects that the fragrance concentration of fragrance A is within or equal to the fragrance concentration threshold, it can dynamically fine-tune the fragrance diffusion level. For example, if the current level is 3, the fragrance diffuser can adjust the level to 2 or 4, and repeatedly adjust between levels 2 and 4 (e.g., every 5 minutes, which can be set according to actual needs, not limited in this application) while the fragrance gas concentration remains within the fragrance concentration threshold or is only slightly different from the fragrance concentration threshold (the difference can be set, not limited in this application) to keep the concentration of fragrance A in the space fluctuating. For fragrance B, the fragrance diffuser can be preset with a larger adjustment range, for example, it can be repeatedly adjusted between levels 2 and 6 to make the concentration of fragrance B in the space fluctuate more. For fragrance C, the diffuser does not need to have a corresponding fluctuation level; that is, fragrance C does not require adjustment of the level to cause fluctuations in its fragrance concentration. It should be noted that the same principle applies when dynamically adjusting the output level of the diffuser. Figure 12 The process is as follows. In another example, the fragrance diffuser can dynamically adjust its output level based on the type of fragrance and the fragrance flow rate, causing the fragrance gas concentration to fluctuate within the space. For example, for fragrance A, if the fragrance diffuser detects that the gas concentration of fragrance A meets the corresponding concentration threshold range, and the fragrance flow rate of fragrance A increases, the diffuser can lower the diffusion level; if the fragrance flow rate decreases, the diffuser can raise the diffusion level, thus causing the fragrance concentration in the space to fluctuate. Other details not described are similar to those above and will not be repeated here.

[0315] In another possible implementation, if the fragrance diffuser detects that the fragrance gas concentration is greater than the fragrance concentration threshold range, and the fragrance gas concentration does not increase (e.g., remains unchanged or decreases), the fragrance diffuser can also dynamically adjust its output level based on the fragrance type, causing the fragrance gas concentration to fluctuate within the space. Similarly, in the embodiments below, if the fragrance diffuser detects that the fragrance gas concentration is less than the fragrance concentration threshold range, and the fragrance gas concentration does not decrease (e.g., remains unchanged or increases), the fragrance diffuser can also dynamically adjust its output level based on the fragrance type, causing the fragrance gas concentration to fluctuate within the space.

[0316] S1204, reduce the output level of the fragrance diffuser.

[0317] S1205, detects whether the concentration of fragrance gas has decreased.

[0318] For example, when the processing module detects that the fragrance gas concentration is less than the fragrance concentration threshold, or that the fragrance gas concentration is less than the minimum value of the fragrance concentration threshold range, the processing module obtains the fragrance flow rate and determines whether the fragrance gas concentration has decreased based on the fragrance flow rate. The judgment process is similar to S1203 and will not be described again here.

[0319] In one example, if the processing module detects that the fragrance flow rate is less than or equal to the fragrance flow rate threshold, that is, when the fragrance gas concentration is less than the fragrance concentration threshold and the fragrance gas concentration is still decreasing, then S1206 is executed, that is, by increasing the fragrance release intensity of the fragrance dispersing device, so that the fragrance gas concentration rises to the fragrance concentration threshold.

[0320] In another example, if the processing module detects that the fragrance flow rate is greater than or equal to the fragrance flow rate threshold, such as when the fragrance concentration increases or remains unchanged (or fluctuates slightly), then 1201 is re-executed. That is, when the fragrance gas concentration is less than the fragrance concentration threshold and is either increasing or remaining unchanged, the processing module may not perform any processing and will repeat S1201 in the next cycle. For details not described, please refer to the relevant description in S807; they will not be repeated here.

[0321] For example, refer to Figure 13 For example, at time t6, the processing module detects that the fragrance gas concentration is less than the fragrance concentration threshold, and the fragrance flow rate is less than the fragrance flow rate threshold. That is, after the fragrance release intensity of the fragrance diffuser is reduced, the fragrance gas concentration in the space drops below the fragrance concentration threshold and continues to decrease. This can also be understood as the fragrance gas concentration being less than the fragrance concentration threshold, and the fragrance gas injection rate in the space still being less than the loss rate. In this case, the processing module can increase the output level of the fragrance diffuser, thereby increasing the fragrance release intensity of the fragrance diffuser, causing the fragrance gas concentration in the space to rise and return to the fragrance concentration threshold.

[0322] In one possible implementation, when the fragrance concentration value is greater than the fragrance concentration threshold, and the fragrance flow rate indicates that the fragrance injection rate is equal to the fragrance loss rate (i.e., the fragrance concentration remains constant at a value greater than the fragrance concentration threshold), optionally, as described above, the processing module may not adjust the fragrance release intensity of the fragrance diffuser. Alternatively, the processing module may also reduce the fragrance release intensity of the fragrance diffuser; this application does not limit this.

[0323] In another possible implementation, when the fragrance concentration value is less than the fragrance concentration threshold, and the fragrance flow rate indicates that the fragrance injection rate is equal to the fragrance loss rate (i.e., the fragrance concentration remains constant at a value less than the fragrance concentration threshold), optionally, as described above, the processing module may not adjust the fragrance release intensity of the fragrance diffuser. Alternatively, the processing module may also increase the fragrance release intensity of the fragrance diffuser; this application does not limit this.

[0324] In another possible implementation, if the fragrance concentration value is equal to or within the fragrance concentration threshold, the processing module may not execute subsequent processes, but instead repeat S1201 in the next cycle.

[0325] It should be noted that the above embodiments are all illustrated by taking the integration of the control device and the fragrance dispersing device in the fragrance device as an example. The devices used in the embodiments of this application are not limited to the structures described above.

[0326] In one example, the processing unit can be a separate device or equipment. For instance, the steps performed by the processing unit can be executed by a device such as a terminal, wearable device, or in-vehicle device. In this scenario, the detection unit and the fragrance dispersing device can be integrated together or be independent of each other.

[0327] In another example, some modules in the detection unit (such as the gas concentration detection module) are integrated with the fragrance dispersing device, while other modules of the detection unit are integrated with the processing unit.

[0328] In another example, the control device and the fragrance dispersing device are integrated, while some modules in the detection unit are independent devices or equipment. The structures shown in the embodiments of this application are merely illustrative examples, and the modules and devices can be combined arbitrarily, which is not limited in this application.

[0329] For example: Figure 14 For an exemplary structural diagram of a fragrance device, please refer to... Figure 14 The fragrance device includes a control unit 100 and a fragrance dispersing device 200. The detection unit 10 within the control unit 100 includes a gas concentration detection module 11 and a temperature and humidity detection module 13. Other modules and their detailed descriptions can be found in [reference needed]. Figure 1This will not be elaborated further here. In this example, the detection unit 10 does not include a gas type detection module. In one example, the user can select the type of fragrance to be released through the user interface provided by the fragrance device's interaction module. The fragrance device can release the corresponding type of fragrance gas in response to the received user operation. In another example, the user can select the type of fragrance to be released through the interaction interface provided by the terminal. The terminal, in response to the received user operation, sends a control signal to the fragrance device, which indicates the type of fragrance selected by the user. The processing module can receive the control signal through the communication module and, based on the control signal, control the fragrance diffuser to release the corresponding type of fragrance gas. For an example, please refer to... Figure 15 The fragrance device includes a fragrance diffusion unit, a processing unit, and a detection unit. The detection unit includes a gas concentration detection module and a temperature and humidity detection module. It should be noted that... Figure 15 The positions of the modules shown are for illustrative purposes only and are not intended to limit the scope of this application. For example, the fragrance pool of the fragrance diffuser includes four fragrances: fragrance A, fragrance B, fragrance C, and fragrance D. Please refer to... Figure 16 Users can click on Fragrance B option 1502 in the smart living interface 1501 to instruct the fragrance device to release the gas corresponding to Fragrance B. (Referring to...) Figure 15 In response to the received user operation, the mobile phone sends a control signal to the fragrance device, indicating that the selected fragrance type is fragrance B. The fragrance device can then release fragrance B gas based on the received control signal.

[0330] In this example, the processing module in the fragrance device can determine the type of fragrance gas currently being released based on received user operations or received control signals. In other words, during execution... Figure 9 In the process described above, the fragrance device does not need to execute S901 to S902; instead, it can execute S903 based on the obtained fragrance type. Furthermore, since the fragrance device does not require a gas type recognition module, the product can be made more compact. It should be noted that the modules in this structure can still refer to... Figure 8 The process is handled in the previous steps, and will not be repeated here.

[0331] Figure 17 For an exemplary schematic diagram of another fragrance device, please refer to... Figure 17 The fragrance device includes a control device 100 and a fragrance dispersing device 200. The detection unit 10 includes a gas concentration detection module. Descriptions of other modules can be found in [reference needed]. Figure 1 This will not be elaborated further here. In this example, the detection unit 10 does not include a gas type identification module or a temperature and humidity detection module. For gas type identification of the device, please refer to... Figure 14The description in the document refers to user-defined settings, which will not be elaborated here. For acquiring temperature and humidity parameters, the processing module can obtain them from the temperature and humidity detection device within the space via the communication module. In other words, in this embodiment, the fragrance device can inherit... Figure 17 The module shown can be used for temperature and humidity detection, while temperature and humidity data can be obtained from existing temperature and humidity detection devices in the space. For example, please refer to [reference needed]. Figure 18 The illustrated scenario, exemplarily, shows a fragrance device including a fragrance diffuser, a processing unit, and a detection unit, where the detection unit includes a gas concentration detection module. A temperature and humidity detection device can be installed in the user's home. For example, the user can log in through the fragrance device's interface or a terminal, giving the fragrance device the same user account as other smart devices in the user's home. This can be understood as devices with the same account (such as the temperature and humidity detection device, the fragrance device, and a mobile phone) communicating via wireless technologies such as Bluetooth and Wi-Fi. Figure 18 This example only illustrates the interaction between devices in a scenario via the cloud. In other embodiments, the temperature and humidity detection device can send the detected temperature and humidity parameters to the fragrance device via Bluetooth (or Wi-Fi). The fragrance device's communication module can receive the temperature and humidity parameters and transmit them to the processing module. (Referring to...) Figure 18 For example, the temperature and humidity detection device can send the detected temperature and humidity parameters to the cloud. Optionally, the cloud is a server cluster consisting of multiple servers. The cloud can send the received temperature and humidity parameters (i.e., temperature and humidity values) to the fragrance device. The communication module of the fragrance device can receive the temperature and humidity parameters and transmit them to the processing module. In this example, by utilizing the temperature and humidity detection device within the existing space, the goal of product miniaturization can be further achieved. It should be noted that the modules in this structure can still refer to... Figure 8 The process is handled in the previous steps, and will not be repeated here.

[0332] It should be further explained that, Figure 17 The various modules and devices within the system, along with the temperature and humidity detection devices in the scene, constitute a fragrance release control system. In other words, a fragrance release control system needs to include a temperature detection device and a gas concentration detection module to obtain... Figure 8 The temperature, humidity, and gas concentration values ​​involved in the process.

[0333] Figure 19 For an exemplary schematic diagram of the fragrance device, please refer to... Figure 19 The fragrance device includes, but is not limited to: a gas concentration detection module 1911, a communication module 1912, and a fragrance dispersing device 1913. Combined with... Figure 19 , Figure 20 For illustrative purposes, please refer to the following scenario diagram. Figure 20A temperature and humidity detection module can be installed in the user's home. This module can send the detected temperature and humidity values ​​to the cloud. The cloud includes at least one server. A gas concentration detection module in the fragrance diffuser can also send the detected gas concentration values ​​to the cloud. Furthermore, the user can set the fragrance type via their mobile phone (specific settings can be found above, and will not be repeated here). The mobile phone can send instructions to the cloud to guide the user in selecting the fragrance type. The cloud processor in the cloud can execute the steps performed by the processing module in the above embodiment, as described above. After determining the required adjustment level for the fragrance diffuser, the cloud processor can send a control signal to the fragrance device to instruct it to adjust to the corresponding level. For example, the communication module in the fragrance device can receive the control signal. Optionally, the fragrance diffuser may include a microprocessor. The communication module can send a corresponding trigger signal to the microprocessor based on the received control signal, causing the microprocessor to adjust the fragrance diffuser to the corresponding level. Undescribed parts can be found in the relevant content of the above embodiment, and will not be repeated here. It should be noted that, with Figure 17 The structure is similar in the middle. Figure 20 The cloud and fragrance devices can form a fragrance release control system. It should be further noted that... Figure 20 This description uses only the cloud-based execution of the functions performed by the processing module in this embodiment as an example. In other embodiments, the functions performed by the processing module can also be performed by terminal devices, in-vehicle devices, smart wearable devices, and other smart home devices. For example, a user's vehicle may be equipped with... Figure 20 The fragrance diffuser includes a communication module and a gas concentration detection module. Additionally, the user's vehicle interior may include a temperature and humidity detection module. For example, the in-vehicle device (also known as a vehicle infotainment system or central control system) can acquire and analyze the parameters obtained by each detection module to adjust the fragrance release intensity of the diffuser. The in-vehicle device can interact with the fragrance diffuser via any means, such as cloud, Bluetooth, or Wi-Fi.

[0334] It should be noted that, in this embodiment, if the control device and the fragrance diffuser are independent devices, and the control device and the fragrance diffuser together constitute a fragrance release system, then the switch options in the user interface can be for the entire fragrance release system. For example, if the user clicks a switch option to turn off the fragrance system, both the control device and the fragrance diffuser in the fragrance system will be turned off. Optionally, the user interface can also have multiple switch options, including switch options corresponding to the control device and switch options corresponding to the fragrance diffuser. For example, the control device in this embodiment can also integrate other functions, such as displaying the current ambient temperature and humidity. Then, the user can turn the fragrance diffuser on or off through the switch options corresponding to the fragrance diffuser in the user interface, and the control device can control the fragrance diffuser to turn on or off in response to the received user operation.
