Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a fragrance release control method, control device, air conditioning equipment, and medium. Background Technology

[0002] As people's living standards improve, more and more people are paying attention to the quality of life and have higher and higher requirements for air comfort. In related technologies, home appliances with air purification functions (such as air purifiers, fresh air systems, and air conditioners) monitor the concentration of indoor pollutants through sensors and display the concentration through numbers or indicator light colors, letting users know the current indoor pollutant situation. However, whether displaying through numbers or indicator lights, it is a passive reminder to the user, requiring the user to specifically observe to understand the specific information. Furthermore, these appliances are small in size, and the display area is not obvious, making it impossible for users to immediately know whether indoor pollutants exceed the standard, nor can they purify and remove pollutants in a timely manner. Summary of the Invention

[0003] This invention aims to at least partially address one of the technical problems in related technologies. Therefore, one object of this invention is to provide a fragrance release control method that can remove indoor pollutants while alerting the user.

[0004] A second objective of this invention is to provide a computer-readable storage medium.

[0005] The third objective of this invention is to provide an air conditioning device.

[0006] The fourth objective of this invention is to provide a fragrance release control device.

[0007] To achieve the above objectives, a first aspect of the present invention provides a fragrance release control method, which includes: detecting the concentration of indoor pollutants; and when it is determined that the concentration of the indoor pollutants exceeds the standard, controlling the release of a fragrance compatible with the indoor pollutants, so as to purify the indoor pollutants while providing a reminder through fragrance release.

[0008] According to the fragrance release control method of the present invention, when the concentration of indoor pollutants exceeds the standard, the method can actively release fragrance corresponding to the indoor pollutants. Since the fragrance has a scent and the function of removing pollutants, it can achieve the purpose of timely reminding users and automatically removing indoor pollutants.

[0009] In one embodiment, determining that the concentration of an indoor pollutant exceeds the standard when there is at least one type of indoor pollutant includes: determining that the concentration of an indoor pollutant exceeds the standard when the concentration of any one of the indoor pollutants is greater than a corresponding preset concentration.

[0010] In one embodiment, controlling the release of a fragrance compatible with the indoor pollutants includes: determining the exceedance rate corresponding to each type of indoor pollutant; determining the type of fragrance to be released and fragrance release logic based on the exceedance rate; and controlling the release of the fragrance corresponding to the type of fragrance to be released based on the fragrance release logic.

[0011] In one embodiment, when there are multiple indoor pollutants exceeding the standard, determining the type of fragrance to be released and the fragrance release logic based on the exceedance rate includes: determining the maximum value of the exceedance rate; determining the type of fragrance to be released based on the indoor pollutants corresponding to the maximum value; and determining the fragrance release logic based on the maximum value.

[0012] In one embodiment, controlling the release of the fragrance corresponding to the fragrance type to be released according to the fragrance release logic includes: determining the air volume and release duration according to the fragrance release logic, controlling the release of the fragrance corresponding to the fragrance type to be released according to the air volume, and when the release time reaches the release duration, re-determining the maximum value of the exceedance rate, and adjusting the fragrance type to be released and the fragrance release logic according to the re-determined maximum value.

[0013] In one embodiment, the air volume and release duration are positively correlated with the maximum value of the exceedance rate.

[0014] In one embodiment, the formula for calculating the exceedance rate is as follows: a = (A - A0) / A0 * 100%, where a represents the exceedance rate, A represents the concentration of indoor pollutants exceeding the standard, and A0 represents the preset concentration of indoor pollutants exceeding the standard.

[0015] In one embodiment, the types of indoor pollutants include particulate matter, formaldehyde, and total volatile organic compounds.

[0016] In one embodiment, controlling the release of a fragrance compatible with the indoor pollutant includes: controlling the release of a negative ion fragrance when the indoor pollutant is particulate matter; controlling the release of a first terpene fragrance when the indoor pollutant is formaldehyde; and controlling the release of a second terpene fragrance when the indoor pollutant is total volatile organic compounds, wherein the concentration of terpenoids in the fragrance corresponding to the first terpene type is different from the concentration of terpenoids in the fragrance corresponding to the second terpene type.

[0017] To achieve the above objectives, a second aspect of the present invention provides a computer-readable storage medium storing a fragrance release control program thereon, which, when executed by a processor, implements the fragrance release control method of any of the above embodiments.

[0018] According to an embodiment of the present invention, a computer-readable storage medium can actively release fragrance corresponding to indoor pollutants when the concentration of indoor pollutants is detected to exceed the standard. Since the fragrance has a pleasant scent and the function of removing pollutants, it can achieve the purpose of timely reminding users and automatically removing indoor pollutants.

[0019] To achieve the above objectives, a third aspect of the present invention provides an air conditioning device, which includes a memory, a processor, and a fragrance release control program stored in the memory and executable on the processor. When the processor executes the fragrance release control program, it implements the fragrance release control method of any of the above embodiments.

[0020] According to an embodiment of the present invention, when the concentration of indoor pollutants exceeds the standard, the air conditioning device can actively release fragrance corresponding to the indoor pollutants. Since the fragrance has a pleasant scent and the function of removing pollutants, it can achieve the purpose of timely reminding users and automatically removing indoor pollutants.

[0021] To achieve the above objectives, a fourth aspect of the present invention provides a fragrance release control device, which includes a detection module and a control module. The detection module is used to detect the concentration of indoor pollutants; the control module is used to control the release of a fragrance compatible with the indoor pollutants when it is determined that the concentration of the indoor pollutants exceeds the standard, so as to purify the indoor pollutants while providing a reminder through fragrance release.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] To clearly illustrate the fragrance release control method, control device, air conditioning equipment, and medium of the present invention, the following description is provided in conjunction with... Figure 1 The flowchart illustrating the fragrance release control method is described below. For example... Figure 1 As shown, the fragrance release control method of this application embodiment includes the following steps:

[0040] S11: Detects the concentration of indoor pollutants;

[0041] S13: When it is determined that the concentration of indoor pollutants exceeds the standard, control the release of fragrances that are compatible with the indoor pollutants, so as to purify the indoor pollutants while giving a reminder through fragrance release.

[0042] According to the fragrance release control method of this invention, when the concentration of indoor pollutants exceeds the standard, a fragrance corresponding to the indoor pollutants can be actively released. Since the fragrance has both a pleasant scent and the function of removing pollutants, it can achieve the purpose of timely reminding users and automatically removing indoor pollutants. Furthermore, because the fragrance is automatically released when the concentration of indoor pollutants exceeds the standard, it does not require manual activation by the user, reducing user operating costs, making the method more intelligent, and improving the user experience.

[0043] Specifically, the fragrance release method of this invention can be used in air conditioning devices, which may include electronic devices such as air conditioners, air purifiers, and fresh air systems. In some embodiments, the air conditioning device may include a "fragrance pollutant detection" function, which the user can control to turn on and off. When the fragrance pollutant detection function is on, the air conditioning device can execute steps S11 and S13; when the fragrance pollutant detection function is off, the air conditioning device does not execute steps S11 and S13. This provides users with multiple options and improves the user experience. In some embodiments, the fragrance pollutant detection function of the air conditioning device is always on. After the air conditioning device is turned on, it can automatically run the fragrance pollutant detection function, and when the concentration of indoor pollutants exceeds the expected standard, it can actively release fragrance to promptly alert the user and remove indoor pollutants.

[0044] In step S11, the types of indoor pollutants may include one or more of particulate matter, formaldehyde, and total volatile organic compounds (TVOC). Particulate matter may include dust particles, dust, fog, smoke, chemical fumes, and soot, etc.

[0045] The concentration of indoor pollutants can be detected using pollutant sensors. In some embodiments, the air conditioning equipment is equipped with multiple pollutant sensors, each capable of detecting the concentration of a specific indoor pollutant. For example, a first pollutant sensor may detect particulate matter, a second may detect formaldehyde, and a third may detect TVOC. Thus, multiple pollutant sensors can detect the concentrations of various indoor pollutants. When indoor pollutant detection is required, multiple pollutant sensors can operate simultaneously to detect the concentrations, or they can detect the concentrations of indoor pollutants sequentially according to a preset order; this is not limited to this method.

[0046] In some embodiments, the air conditioning device is equipped with a pollutant detection module that integrates multiple pollutant detection units. Each pollutant detection unit can detect the concentration of one indoor pollutant, so that one pollutant detection module can detect the concentration of multiple indoor pollutants.

[0047] The detection cycle for indoor pollutant concentration can be once every 1 second, every 2 seconds, or at other intervals. The detection cycle can be fixed or dynamically adjusted based on the concentration of indoor pollutants or other factors. For example, when the concentration of indoor pollutants is within the standard range, the detection cycle can be appropriately shortened to facilitate timely detection; when the concentration of indoor pollutants exceeds the standard and fragrances are being released, the detection cycle can be appropriately extended to reduce power consumption. The concentration of indoor pollutants can be determined based on the result of a single test or by averaging the results of multiple tests (e.g., 30 or 50 tests).

[0048] In step S13, a first correspondence between each indoor pollutant and a fragrance type can be pre-established. This can be one indoor pollutant corresponding to one fragrance type, or one indoor pollutant corresponding to multiple fragrance types; no limitation is made here. Thus, when the concentration of a certain indoor pollutant exceeds the standard, the fragrance type to be released can be determined based on the type of indoor pollutant exceeding the standard and the first correspondence. It is understood that in some embodiments, the fragrance may include identification information, which may include the fragrance type. The fragrance type can be understood as an inherent attribute of the fragrance, and the fragrance type is determined before the fragrance leaves the factory. When the fragrance is used in conjunction with an air conditioning device, for example, when the fragrance is placed in the fragrance bottle of the air conditioning device, the air conditioning device can read the identification information of the placed fragrance and determine the fragrance type of the placed fragrance. Thus, when the air conditioning device determines the fragrance type to be released based on the detected indoor pollutants, it can control the release of the fragrance corresponding to that fragrance type. It is understandable that releasing fragrance is to purify a certain indoor pollutant that exceeds the standard. If another indoor pollutant exists in the indoor environment, but the concentration of the other indoor pollutant does not exceed the standard, then the fragrance corresponding to the indoor pollutant that does not exceed the standard will not be released.

[0049] It should be noted that the unique physical properties and / or chemical composition of fragrances enable them to remove indoor pollutants. In some embodiments, fragrances can be pre-formulated to target the physicochemical properties of indoor pollutants for their removal. The physical properties and chemical composition of each fragrance are not entirely identical.

[0050] In one example, considering that particulate matter is usually positively charged, negative ion fragrances containing ingredients such as birch and / or rosewood can be used to remove particulate matter from the indoor environment. These fragrances possess negative ion properties and carry a negative charge. When released into the indoor environment, the negatively charged fragrance attracts and binds to the positively charged particulate matter, causing them to aggregate into larger particles that settle to the ground, thus purifying the air.

[0051] In one example, considering that terpenes can interact with formaldehyde to decompose it, a first-terpene fragrance containing ingredients such as lemongrass and / or tea tree can be used to remove formaldehyde from the indoor environment. First-terpene fragrances containing lemongrass and / or tea tree contain a certain concentration of terpenes. When released into the indoor environment, the terpenes in the fragrance can interact with formaldehyde, thereby achieving the effect of decomposing formaldehyde and purifying indoor pollutants.

[0052] In one example, considering the high reactivity and broad reaction spectrum of terpenes, and their ability to decompose TVOCs through interaction, a second-terpene fragrance containing one or more of juniper, pine needles, and bitter orange can be used to remove TVOCs from the indoor environment. This second-terpene fragrance contains a certain concentration of terpenes. When released into the indoor environment, these terpenes interact with TVOCs, thus decomposing them and purifying indoor pollutants. Understandably, the higher the concentration of terpenes in the fragrance, the better the effect of purifying formaldehyde and TVOCs.

[0053] In one example, under the same airflow conditions, the efficiency of different fragrance components in removing corresponding indoor pollutants after one hour is shown in Table 1. The fragrance with birch component can remove 35% of particulate matter in the indoor environment after one hour, the fragrance with rosewood component can remove 32% of particulate matter in the indoor environment after one hour, the fragrance with lemongrass component can remove 22% of formaldehyde in the indoor environment after one hour, the fragrance with tea tree component can remove 21% of formaldehyde in the indoor environment after one hour, the fragrance with juniper component can remove 26% of TVOC in the indoor environment after one hour, the fragrance with pine needle component can remove 23% of TVOC in the indoor environment after one hour, and the fragrance with bitter orange component can remove 20% of TVOC in the indoor environment after one hour. It can be seen that releasing fragrances corresponding to indoor pollutants can effectively purify indoor pollutants.

[0054] Table 1

[0055]

[0056] In one embodiment, when there is at least one type of indoor pollutant, the "determining that the concentration of indoor pollutants exceeds the standard" in step S13 includes: determining that the concentration of indoor pollutants exceeds the standard when the concentration of any indoor pollutant is greater than the corresponding preset concentration.

[0057] In this way, it is possible to accurately determine whether indoor pollutants exceed the standard.

[0058] Specifically, the types of indoor pollutants can be one, two, three, or more than three, without limitation. The preset concentration can be the limit for pollutant concentration exceeding the national standard, or it can be a user-defined limit. Each indoor pollutant corresponds to one preset concentration, and the preset concentrations for each type of indoor pollutant can be the same or different. When the concentration of each indoor pollutant is less than or equal to its corresponding preset concentration, it can be determined that the concentration of indoor pollutants does not exceed the standard.

[0059] In one example, the indoor pollutants include particulate matter, formaldehyde, and TVOC, with different preset concentrations for each. Specifically, the preset concentration for particulate matter is 75 μg / m³. 3 The preset concentration of formaldehyde is 0.1 mg / m³. 3 The preset concentration of TVOC is 0.6 mg / m³. 3 That is to say, when the concentration of particulate matter is greater than 75 μg / m³ 3 Or the formaldehyde concentration is greater than 0.1 mg / m³ 3 Or the concentration of TVOC is greater than 0.6 mg / m³ 3 At any time, it can be determined that indoor pollutants exceed the standard; when the concentration of particulate matter is less than or equal to 75 μg / m³, it can be determined that indoor pollutants exceed the standard. 3 Furthermore, the formaldehyde concentration is less than or equal to 0.1 mg / m³. 3 And the concentration of TVOC is less than or equal to 0.6 mg / m³ 3 At that time, it can be determined that indoor pollutants do not exceed the standard.

[0060] Please see Figure 2 In one embodiment, step S13, "controlling the release of fragrances adapted to indoor pollutants," includes:

[0061] S131: Determine the exceedance rate for each type of indoor pollutant that exceeds the standard;

[0062] S132: Determine the type of fragrance to be released and the fragrance release logic based on the exceedance rate;

[0063] S133: Based on the fragrance release logic, control the release of the fragrance corresponding to the fragrance type to be released.

[0064] In this way, the corresponding indoor pollutants can be effectively purified and the user will be alerted.

[0065] Specifically, in one embodiment, the exceedance rate is calculated using the following formula: a = (A - A0) / A0 * 100%, where a represents the exceedance rate, A represents the concentration of the exceedance indoor pollutant, and A0 represents the preset concentration corresponding to the exceedance indoor pollutant. Thus, when the preset concentrations for each indoor pollutant are different, the severity of each exceedance indoor pollutant can be compared by uniformly converting the measured concentrations into exceedance rates. This also simplifies the fragrance release logic, eliminating the need to develop separate fragrance release logic for each type of indoor pollutant.

[0066] In one example, the detected formaldehyde concentration was 0.3 mg / m³. 3 The preset concentration for formaldehyde is 0.1 mg / m³. 3If the formaldehyde concentration in the current indoor environment exceeds the standard, then the excess rate of formaldehyde is a = (0.3-0.1) / 0.1*100% = 20%.

[0067] Furthermore, the types of indoor pollutants can be determined based on the exceedance rate, and then the type of fragrance to be released can be determined by combining the pre-established first correspondence between each indoor pollutant and fragrance type. A second correspondence between the exceedance rate and the fragrance release logic can be pre-established. This could be one exceedance rate value corresponding to one fragrance release logic, or a range of exceedance rate values ​​corresponding to one fragrance release logic; that is, multiple exceedance rate values ​​corresponding to one fragrance release logic. Thus, after determining the exceedance rate, the corresponding fragrance release logic can be determined by combining the second correspondence.

[0068] In some embodiments, the first and second correspondences can be stored in the local database of the air conditioning device. After determining the exceedance rate, the air conditioning device can directly retrieve the first and second correspondences from the local database to determine the corresponding fragrance type to be released and the fragrance release logic.

[0069] In some embodiments, the first and second correspondences can be stored in a database in the cloud. The air conditioning device can communicate with the cloud and obtain the first and second correspondences stored in the cloud. Then, after determining the exceedance rate, the air conditioning device can determine the corresponding fragrance type to be released and the fragrance release logic based on the first and second correspondences obtained from the cloud.

[0070] In some embodiments, the first and second correspondences can be stored in a cloud database. The air conditioning device can communicate with the cloud and upload the calculated exceedance rate to the cloud. The cloud determines the corresponding fragrance type to be released and fragrance release logic based on the received exceedance rate, the first and second correspondences, and then sends the fragrance type to be released and fragrance release logic to the air conditioning device, so that the air conditioning device can determine the corresponding fragrance type to be released and fragrance release logic.

[0071] Please see Figure 3 In one embodiment, when there are multiple indoor pollutants exceeding the standard, step S132 includes:

[0072] S1321: Determine the maximum value of the exceedance rate;

[0073] S1323: Determine the type of fragrance to be released based on the indoor pollutants corresponding to the maximum value, and determine the fragrance release logic based on the maximum value.

[0074] In this way, it can effectively purify indoor pollutants, prioritizing the purification and highlighting of the most severely polluting indoor pollutants, and can prevent the simultaneous release of multiple fragrances from causing discomfort to users.

[0075] In one example, the indoor pollutants exceeding the standard include TVOC and formaldehyde, with TVOC exceeding the standard by 30% and formaldehyde exceeding the standard by 5%. Since TVOC has the highest exceeding rate, the fragrance type to be released is determined to be the second terpene type based on TVOC, and the fragrance release logic is determined based on 30%.

[0076] In one example, when the maximum exceedance rate is less than the first threshold, the first fragrance release logic is used; when the maximum exceedance rate is greater than or equal to the first threshold and less than or equal to the second threshold, the second fragrance release logic is used; when the maximum exceedance rate is greater than the second threshold, the third fragrance release logic is used, where the first threshold is less than the second threshold.

[0077] Please see Figure 4 In one embodiment, step S133 includes:

[0078] S1331: Determine the air volume and release duration based on the fragrance release logic, and control the release of the fragrance corresponding to the fragrance type to be released based on the air volume. When the release time reaches the release duration, redetermine the maximum value of the exceedance rate, and adjust the fragrance type to be released and the fragrance release logic based on the redetermined maximum value.

[0079] In this way, the fragrance can be released more effectively, achieving the goal of purifying the most severe indoor pollutants. Simultaneously, because the concentration of indoor pollutants is checked at preset intervals during the fragrance release process, the detection cycle is longer when the indoor pollutant concentration exceeds the standard and the fragrance is being released than when the indoor pollutant concentration is within the standard and the fragrance is not being released. Therefore, frequent monitoring of indoor pollutant concentration is unnecessary during fragrance release, saving power.

[0080] Specifically, the fragrance release logic can include multiple types, and the airflow and release duration corresponding to each fragrance release logic can be different or partially the same. In some embodiments, the first fragrance release logic corresponds to a first airflow and a first release duration, and the second fragrance release logic corresponds to a second airflow and a second release duration, wherein the first airflow and the second airflow are different, and the first release duration and the second release duration are different; in other embodiments, the first fragrance release logic corresponds to the first airflow and the first release duration, and the second fragrance release logic can correspond to the first airflow and the second release duration, or the second fragrance release logic corresponds to the second airflow and the first release duration, without limitation. A third correspondence between fragrance release logic and airflow and preset duration can be pre-established and stored, so that after determining the fragrance release logic, the airflow and preset duration can be quickly determined according to the third correspondence. In some embodiments, the airflow and release duration corresponding to each fragrance release logic can also be customized by the user to meet the usage needs of different users.

[0081] Furthermore, in some embodiments, the area of ​​the air outlet is fixed. In this case, the air volume corresponds to the rotation speed of the air outlet fan. The larger the air volume, the faster the air outlet fan is controlled to run, thereby quickly releasing the fragrance. The smaller the air volume, the slower the air outlet fan is controlled to run, thereby slowly releasing the fragrance.

[0082] It is understandable that when the type of indoor pollutant corresponding to the maximum re-detected exceedance rate remains unchanged, the type of fragrance to be released remains the same, while the fragrance release logic is adjusted based on the re-obtained maximum exceedance rate. When the type of indoor pollutant corresponding to the maximum re-detected exceedance rate changes, the type of fragrance to be released is adjusted to the fragrance type corresponding to the type of indoor pollutant corresponding to the maximum re-detected exceedance rate, and the fragrance release logic is adjusted based on the re-obtained maximum exceedance rate. When it is determined that the concentration of indoor pollutants is within acceptable limits, fragrance release ceases, and the concentration of indoor pollutants is detected at intervals shorter than the preset detection time. This ensures timely detection and purification when the concentration of indoor pollutants exceeds the limit, thus protecting air quality.

[0083] In one embodiment, the air volume and release duration are positively correlated with the maximum exceedance rate.

[0084] Thus, when the pollution level is more severe, a higher air volume and a longer release time are used to generate a higher fragrance concentration indoors. A higher fragrance concentration can better react with indoor pollutants, and a higher fragrance concentration has a stronger scent, thereby achieving the effect of removing indoor pollutants more quickly and providing a more obvious reminder to users.

[0085] In one example, the correspondence between the fragrance release logic and the maximum exceedance rate is shown in Table 2. When the maximum exceedance rate is less than 10%, the fragrance release logic is at level I, with a corresponding airflow of 20% and a preset duration of 15 minutes. When the maximum exceedance rate is greater than or equal to 10% and less than or equal to 50%, the fragrance release logic is at level II, with a corresponding airflow of 50% and a preset duration of 20 minutes. When the maximum exceedance rate is greater than 50%, the fragrance release logic is at level III, with a corresponding airflow of 70% and a preset duration of 30 minutes.

[0086] Table 2

[0087]

[0088] In one embodiment, the types of indoor pollutants include one of particulate matter, formaldehyde, and total volatile organic compounds.

[0089] In other words, the current indoor environment only has excessive concentrations of particulate matter, or only excessive concentrations of formaldehyde, or only excessive concentrations of TVOC.

[0090] Please see Figure 5 In one embodiment, step S13, "controlling the release of fragrances adapted to indoor pollutants," includes:

[0091] S134: When the indoor pollutant is particulate matter, control the release of negative ion fragrance;

[0092] S135: When the indoor pollutant is formaldehyde, control the release of first terpene fragrance;

[0093] S136: When the indoor pollutant is total volatile organic compounds, the release of the second terpene-type fragrance is controlled, wherein the concentration of terpenoids in the fragrance corresponding to the first terpene type is different from the concentration of terpenoids in the fragrance corresponding to the second terpene type.

[0094] Therefore, when the types of indoor pollutants exceeding the standard include particulate matter, formaldehyde, and total volatile organic compounds, it is not necessary to determine the type of fragrance to be released based on the exceedance rate; the corresponding fragrance can be released directly according to the type of indoor pollutant.

[0095] Specifically, the fragrance ingredients for negative ion fragrances may include birch or rosewood, or a combination of both. The fragrance ingredients for first terpene fragrances may include lemongrass or tea tree, or a combination of both. The fragrance ingredients for second terpene fragrances may include one or more of juniper, pine needles, and bitter orange.

[0096] It is understandable that when the types of indoor pollutants exceeding the standard include particulate matter, formaldehyde, and total volatile organic compounds, the fragrance release logic can be directly determined based on the exceedance rate of that pollutant. Then, the airflow and release duration are determined according to the fragrance release logic, and the corresponding fragrance is released based on the airflow. When the release time reaches the specified duration, the concentration of indoor pollutants is re-tested. Specifically, if only one type of indoor pollutant is detected as exceeding the standard, the type of fragrance to be released is adjusted to match that pollutant, and the fragrance release logic is adjusted according to the exceedance rate of that pollutant before releasing the fragrance. If more than one type of indoor pollutant is detected as exceeding the standard, the type of indoor pollutant corresponding to the maximum exceedance rate is determined, and the type of fragrance to be released is adjusted to preferentially match that pollutant. The fragrance release logic is adjusted according to the maximum exceedance rate before releasing the fragrance. If none of the indoor pollutants are detected as exceeding the standard, no fragrance is released, the testing cycle is adjusted, and the indoor environment is continuously monitored.

[0097] In one embodiment of the present invention, the air conditioning device includes a fragrance device, which includes a base, a switching element, and a drive assembly. The base has a mounting cavity and is provided with an air inlet and an air outlet communicating with the mounting cavity. The switching element is movably disposed inside the mounting cavity and has multiple receiving cavities. Each receiving cavity contains a fragrance bottle, and the fragrance bottle has an air hole communicating with the receiving cavity. The drive assembly is connected to the switching element and drives the switching element to move within the mounting cavity, so that the receiving cavities can alternately communicate with the air inlet and the air outlet. An exhaust fan is provided corresponding to the air outlet. Each fragrance bottle contains a different fragrance, and different types of fragrances can be switched using the drive assembly and the switching element.

[0098] Specifically, such as Figure 6 and Figure 7As shown, the fragrance device 10 includes a base 11, a switching element 13, and a drive assembly 14. The base 11 has a mounting cavity and is provided with an air inlet 11a and an air outlet 11b communicating with the mounting cavity. The switching element 13 is movably disposed inside the mounting cavity and has multiple receiving cavities. Each receiving cavity contains a fragrance bottle 12, and each fragrance bottle 12 has an air hole 12a communicating with the receiving cavity. In an optional embodiment, there are multiple air holes 12a. The drive assembly 14 is connected to the switching element 13 and drives the switching element 13 to move within the mounting cavity, so that the receiving cavities can alternately communicate with the air inlet 11a and the air outlet 11b. Specifically, each of the multiple receiving cavities contains a relatively independent fragrance bottle 12, and each fragrance bottle 12 can hold different types and scents of fragrance. After determining the type of fragrance to be released, the receiving cavity containing the fragrance bottle 12 is aligned with the air inlet 11a and the air outlet 11b to release the fragrance. Furthermore, the switching element 13 has a relatively simple structure, while fragrance devices with fragrance switching functions in related technologies have internal solenoid valves and complex structures. This invention also solves the problem of complex fragrance switching and reduces the manufacturing cost of the fragrance device 10 with fragrance switching function.

[0099] Please see Figure 8 In one optional embodiment, the switching element 13 includes a top plate 131, a bottom plate 133, and a plurality of partitions 132 disposed between the top plate 131 and the bottom plate 133. A receiving cavity is formed between two adjacent partitions 132. The driving assembly 14 drives the switching element 13 to rotate, so that one of the receiving cavities communicates with the air inlet 11a and the air outlet 11b. Specifically, the switching element 13 is a rotating cylinder that rotates within the base 11. Further, in addition to the top plate 131, bottom plate 133, and partitions 132, the switching element 13 also has a support column connecting the top plate 131 and the bottom plate 133 in the middle. The support column also has a rotating shaft hole for the rotating shaft to pass through. The plurality of partitions 132 are spaced apart circumferentially along the support column. The driving assembly 14 extends into the rotating shaft hole to drive the switching element 13 to rotate. In another embodiment, in addition to rotation, the switching element 13 can also achieve fragrance switching in various other ways, such as sliding or pulling. In another embodiment, the base 11 is provided with an air inlet 11a and an air outlet 11b. The switching member 13 moves axially relative to the base 11, and the receiving cavity is also arranged axially corresponding to the base 11. The receiving cavity aligned with the air inlet 11a and the air outlet 11b can be changed by the axial movement of the switching member 13.

[0100] Please see Figure 7In an optional embodiment, the inner wall of the base 11 is provided with a protrusion 11c, which is located between the air inlet 11a and the air outlet 11b. When one of the accommodating cavities is connected to the air inlet 11a and the air outlet 11b, the protrusion 11c and the two adjacent partitions 132 together form an air duct, which guides the airflow through the fragrance bottle 12. Optionally, the base 11 includes a cylindrical base 11 body and an externally connected flow guide. The switching member 13 is installed inside the base 11 body, and the air inlet 11a, the air outlet 11b, and the protrusion 11c are all located on the flow guide. This forms an air duct that allows the airflow to pass through the fragrance bottle 12. In this way, most of the airflow can pass through the fragrance bottle 12 through this air duct, so that the airflow flowing out of the fragrance device 10 carries more fragrance, thereby improving the user experience.

[0101] In an optional embodiment, when one of the accommodating cavities is connected to the air inlet 11a and the air outlet 11b, the air inlet 11a is located between the protrusion 11c and one of the partitions 132, and the air outlet 11b is located between the protrusion 11c and the other partition 132. This arrangement is to avoid the situation where the air outlet 11b or the air inlet 11a is simultaneously located on both sides of the partition 132. That is, only one accommodating cavity is connected to the air inlet 11a and the air outlet 11b at a time. This arrangement can minimize the impact of the fragrance bottles in the other accommodating cavities on the fragrance device.

[0102] In an optional embodiment, there is a gap between the partition 132 and the inner wall of the base 11. During the rotation of the switching member 13, a small gap exists between the partition 132 and the inner wall of the base 11 in order to ensure the smooth rotation of the switching member 13. However, most of the airflow passing through this gap still flows in from the air inlet 11a, passes through the spice bottle 12 via the air hole 12a, and flows out from the air outlet 11b.

[0103] Please see Figure 9 , Figure 10 In an optional embodiment, the height of the fragrance bottle 12 is greater than the distance between the top plate 131 and the bottom plate 133. The top plate 131 has a through hole for the fragrance bottle 12 to extend out, and the bottom of the fragrance bottle 12 is detachably connected to the bottom plate 133. In related technologies, fragrance bottles are often fixedly connected to a fragrance device or housed within the device. When a user wants to change the fragrance or remove the bottle, the entire fragrance device needs to be disassembled, a complex and difficult process. However, in the fragrance device 10 proposed in this invention, the fragrance bottle 12 extends out of the switching member 13 through the through hole on the top plate 131. The user can easily remove the fragrance bottle 12 from the fragrance device 10 through the extended portion. It can be seen that... Figure 9 This is a top view of the top plate 131 of the switching component 13. Figure 10This is a cross-sectional view taken along line AA after the spice bottle 12 is installed on the switching component 13. It can be seen that, in addition to the pivot hole, the top plate 131 also has through holes for the spice bottle 12 to extend out. The number of these through holes corresponds one-to-one with the number of spice bottles 12.

[0104] It is worth noting that, to facilitate the removal of the spice bottle 12, although there is a gap between the inner wall of the through hole on the top plate 131 and the spice bottle 12, the width of this gap is small, and its impact on airflow is minimal. When the airflow flows into the receiving cavity through the air outlet 11b, due to the relatively narrow gaps between the partition plate 132 and the inner wall of the base 11, and between the spice bottle 12 and the top plate 131, most of the airflow flows in through the air inlet 11a, passes through the vent 12a through the spice bottle 12, and then flows out through the air outlet 11b. Brownian motion refers to the ceaseless, random motion of particles suspended in a liquid or gas. It is named after the British botanist Brown, who discovered it. The diameter of particles undergoing Brownian motion is generally 10⁻⁵–10⁻³ cm. When these small particles are in a liquid or gas, due to the thermal motion of liquid molecules, the particles are subjected to collisions from liquid molecules in all directions. When subjected to unbalanced impacts, they move. Due to these unbalanced impacts, the motion of the particles constantly changes direction, resulting in irregular motion. The intensity of Brownian motion increases with the temperature of the fluid. The working principle of the fragrance device 10 is to carry fragrance molecules into the air through airflow, and the fragrance molecules undergo Brownian motion in the air. It can be seen that due to the existence of Brownian motion, the distribution of fragrance molecules in the air is relatively dispersed, and a large number of fragrance molecules are needed to make the air fragrant.

[0105] The existence of gaps between partition 132 and base 11, and between top plate 131 and fragrance bottle 12, may allow some airflow to escape through these gaps. This portion of airflow is relatively small compared to the total amount of airflow passing through the fragrance device 10. The airflow passing through the fragrance tank carries aroma primarily because it carries fragrance compound molecules as it passes through the fragrance tank, causing these molecules to diffuse in the air and thus impart fragrance. If only a small portion of the airflow enters the fragrance tank, the total amount of aroma molecules it carries after merging with the rest will be small. Furthermore, due to the diffusion of aroma molecules in the air—that is, their random movement—the final concentration of aroma molecules in the air is negligible and has almost no impact on the odor in the air.

[0106] Please see Figure 11In one optional embodiment, a mounting hole is provided on the top of the base 11. The switching component 13 is inserted into the base 11 through the mounting hole. A limiting ring 15 is also provided on the top of the base 11 to prevent the switching component 13 from falling out of the mounting hole. Multiple fragrance bottles 12 are located inside the limiting ring 15. Specifically, the switching component 13 is inserted into the base 11 through the mounting hole and connected to the drive mechanism before the limiting ring 15 is installed. Further, the diameter of the limiting ring 15 is smaller than the diameter of the mounting hole and smaller than the diameter of the switching component 13. However, since the fragrance bottles 12 extend at least partially from the switching component 13, each fragrance bottle 12 is located inside the limiting ring 15. That is, the protruding fragrance bottles 12 are directly visible from the top of the fragrance device 10, and the setting of the limiting ring 15 does not affect the removal and placement of the fragrance bottles 12. Since the switching element 13 is movable inside the mounting cavity, if its vertical movement is not restricted, it can easily detach from the base 11 through the mounting hole. Furthermore, the retaining ring can be installed outside the base 11 or positioned between the base 11 and the switching element 13. For ease of installation, the limiting ring 15 is located inside the base 11, allowing it to be installed directly outside the base 11 after the switching element 13 is inserted.

[0107] Please see Figure 8 In one optional embodiment, a first magnetic element 123 is provided at the bottom of the spice bottle 12, and a corresponding second magnetic element 134 is provided on the base plate 133. Optionally, the first magnetic element 123 is an iron sheet, and the second magnetic element 134 is a permanent magnet. In another embodiment, both the first magnetic element 123 and the second magnetic element 134 may be permanent magnets. Optionally, a mounting base for mounting the permanent magnet is also provided on the base plate 133. The spice bottle 12 is fixed in the switching component 13 by magnetic attraction. When the user needs to remove the spice bottle 12, he / she only needs to hold the part of the spice bottle 12 that extends out of the top plate 131 and apply an upward force to the spice bottle 12 to easily remove it. There is no need to disassemble the spice device 10 separately, simplifying the steps of replacing and replenishing the spice bottle 12. When the spice bottle 12 does not need to be removed, the first magnetic element 123 and the second magnetic element 134 are attracted together and firmly fix the spice bottle 12. In addition, the spice bottle 12 can be detachably fixed to the base plate 133 by means of snap-fit ​​or other means.

[0108] Please see Figure 8In one optional embodiment, the fragrance bottle 12 includes a bottle body 122 and a cap 121. The bottle body 122 is at least partially located within the receiving cavity. An air vent 12a is provided on the bottle body 122 and communicates with the receiving cavity. The cap 121 is located outside the receiving cavity and is detachably disposed at the opening of the bottle body 122. Thus, when the fragrance in the fragrance bottle 12 is depleted, the user can open the cap 121 to replace or replenish the fragrance in the fragrance bottle 12. It is worth noting that in one embodiment, the bottle body 122 may be completely located within the receiving cavity. In this case, the cap 121 is connected to the bottle body 122 through a through hole on the top plate 131. The cap 121 may be completely located outside the receiving cavity or partially located outside the receiving cavity. In another embodiment, only part of the bottle body 122 is located within the receiving cavity, while a portion extends out through the through hole on the top plate 131. It is worth noting that the vent 12a should be connected to the receiving cavity, that is, the vent 12a is located in the part of the bottle body 122 located in the receiving cavity.

[0109] Please see Figure 10 In one optional embodiment, the vents 12a are arranged in an array. Further, the body 122 of the fragrance bottle 12 is cylindrical, and the array of vents 12a is distributed on the cylindrical body 122. This arrangement facilitates sufficient gas exchange between the airflow flowing in from the air inlet 11a and the fragrance inside the fragrance bottle 12 as it passes through the bottle. This ensures that the airflow exiting from the air outlet 11b carries sufficient fragrance to meet user needs. Optionally, the fragrance inside the fragrance bottle 12 can be a solid fragrance. An array, or matrix, refers to a rectangular array arranged side-by-side in an array. This arrangement makes the fragrance container easy to process, and also facilitates sufficient airflow exchange, ensuring that the airflow passing through the fragrance container carries sufficient fragrance to meet user needs.

[0110] Please see Figure 11In an optional embodiment, the drive assembly 14 includes a Geneva intermittent motion mechanism and a motor 143. The Geneva intermittent motion mechanism includes an active Geneva 141 and a passive Geneva 142. The active Geneva 141 is connected to the motor 143 and the passive Geneva 142, and the passive Geneva 142 is connected to the switching element 13. The Geneva intermittent motion mechanism can precisely control the rotation angle. In one embodiment, there are four spice bottles 12, which corresponds to four receiving slots. When switching the receiving cavity connected to the air inlet 11a and the air outlet 11b, it is necessary to precisely control the rotation angle of the switching element 13 to 90 degrees or a multiple of 90 degrees. The Geneva intermittent motion mechanism meets this requirement for precise rotation angle control. Specifically, the rotation angle of the passive Geneva 142 can be controlled by controlling the number of slots on the passive Geneva 142. In an optional embodiment, the passive Geneva 142 has four slots. When the active Geneva 141 rotates one revolution, it drives the passive Geneva 142 to rotate 90 degrees. In one embodiment, if the number of spice bottles 12 is N, then the number of accommodating cavities and the number of slots in the passive Geneva wheel 142 are both N. The active Geneva wheel 141 rotates one revolution, and the passive Geneva wheel 142 rotates 360° / N. Furthermore, the Geneva wheel intermittent motion mechanism has advantages such as simple structure, easy processing, reliable operation, and high mechanical efficiency. Compared to a ratchet mechanism, the Geneva wheel mechanism moves more smoothly during engagement and disengagement. In addition, the Geneva wheel intermittent motion mechanism has lower control requirements for the motor 143; the precise angle control of the drive assembly 14 is achieved through the structural design of the Geneva wheel, rather than relying on the precise control of the motor 143. Therefore, using a Geneva wheel intermittent motion mechanism can also greatly reduce the manufacturing cost of the spice device 10.

[0111] Optionally, the driven grooved wheel 142 has N radial grooves, the number of which corresponds to the number of accommodating cavities. When the driving grooved wheel 141 rotates one revolution, the driven grooved wheel 142 rotates 1 / N revolutions. Optionally, N can be 4. The intermittent motion mechanism of the grooved wheel is an external grooved wheel motion mechanism. For the external grooved wheel mechanism, the driving grooved wheel 141 is provided with a round pin, and the driven grooved wheel 142 is provided with multiple radial grooves for the movement of the round pin. To avoid axial force, the grooves of the driven grooved wheel 142 are generally opened in the radial direction of the driven grooved wheel 142. In addition, the driving grooved wheel 141 is provided with an outwardly convex locking arc, and the driven grooved wheel 142 is provided with an inwardly concave locking arc. When the motor 143 drives the driving grooved wheel 141 to rotate continuously, before the round pin enters the groove of the driven grooved wheel 142, the outwardly convex locking arc on the driving grooved wheel 141 locks the inwardly concave locking arc on the driven grooved wheel 142, and the driven grooved wheel 142 does not rotate at this time. When the pin enters the groove, the concave locking arc on the driven groove wheel 142 disengages from the convex locking arc, causing the driven groove wheel 142 to rotate. When the pin leaves the radial groove locking arc from the other side and is locked again, the driven groove wheel 142 stops moving until the pin enters another groove. This achieves precise control of intermittent motion and angle.

[0112] Please see Figure 12 , Figure 13 , Figure 14 In an optional embodiment, the fragrance device 10 further includes a housing and a fixing member. The motor 143 and the intermittent motion mechanism of the Geneva wheel are both disposed within the housing. Fixing holes are provided on both the housing and the base 11, and the fixing member is used to pass through the fixing holes to fix the housing and the base 11 together. For aesthetic purposes and to prevent damage to the drive mechanism, the fragrance device 10 also includes a housing for protecting the drive assembly 14. Specifically, the housing includes a first housing 144a and a second housing 144b. The first housing 144a and the bottom of the base 11 together form a cavity, and the intermittent motion mechanism of the Geneva wheel is disposed within this cavity. The motor 143 is disposed within the cavity formed by the second housing 144b and the first housing 144a. In one embodiment, a protruding ridge and a fixing hole penetrating the cam are formed on the side of the base 11. The limiting ring 15, the first housing 144a, and the second housing 144b are each provided with fixing holes corresponding to one or more of them. During the assembly of the spice device 10, the connection between the base 11 and the first housing 144a, the connection between the first housing 144a and the second housing 144b, and the connection between the limiting ring 15 and the base 11 are all achieved through fasteners.

[0113] Please see Figure 7 In one optional embodiment, the number of fragrance bottles 12 is not less than 2 and not more than 10. With the fragrance device 10 including multiple fragrance bottles 12, the number of fragrance bottles 12 is controlled between 2 and 10, which can satisfy the need to provide users with a variety of fragrance types. This simplifies the structure of the fragrance device 10 and reduces manufacturing costs. It is worth noting that in the fragrance device 10 proposed in this invention, the number of fragrance bottles 12 corresponds one-to-one with the number of receiving cavities and the number of slots on the passive grooved wheel 142. In one embodiment, the number of fragrance bottles 12, receiving cavities, and slots are all 4.

[0114] Please refer to Figure 15 The air conditioning equipment can be an air conditioner, such as the indoor unit 100 of an air conditioner, which includes the aforementioned fragrance device 10. Specifically, the fragrance device 10 is configured to emit fragrance into the room according to the user's needs, thereby increasing the pleasant aroma and achieving the effect of enhancing the user's sense of pleasure or eliminating odors.

[0115] In an optional embodiment, the air conditioner indoor unit 100 includes a main unit 30 and a sub-unit 20. The main unit 30 has an indoor heat exchange module. The specific structure of the heat exchange module of the main unit 30 can refer to the existing technology of air conditioner indoor units, especially floor-standing air conditioner indoor units. The sub-unit 20 has an air outlet function to achieve the effect of blowing and regulating the indoor air. Furthermore, the sub-unit 20 can be detachably connected to the main unit 30. This allows the sub-units 20 to regulate the indoor air in a way that is interconnected or independent, ensuring that the heat exchange effect of the indoor heat exchange module is not affected when the sub-units 20 are connected to or disconnected from the main unit 30. This ensures the heat exchange stability of the air conditioner indoor unit 100. A fragrance device 10 is disposed in the sub-unit 20 to emit fragrance into the room. In an optional embodiment, the fragrance device 10 can be installed in the air duct of the air conditioner indoor unit 100. In this way, the fragrance device 10 is used to emit fragrance into the room to increase the aroma of the indoor environment and eliminate odors. It is understood that the sub-unit 20 can emit fragrance in different areas according to the user's needs.

[0116] Specifically, the main unit 30 is provided with a receiving cavity for accommodating the sub-unit 20. The sub-unit 20 has two states: contained within the receiving cavity and detached from the receiving cavity. Optionally, the specific connection structure between the sub-unit 20 and the main unit 30 can be snap-fit, magnetically attached, connected, or plugged in. In an optional embodiment, when the sub-unit is in a non-operating state, the sub-unit 20 is completely contained within the receiving cavity. Of course, the sub-unit 20 can also be partially located within the receiving cavity and partially located outside the receiving cavity, i.e., partially exposed outside the main unit 30. In one embodiment, the sub-unit 20 is installed at the lower part of the main unit 30 and is provided with a moving component. Optionally, the moving component is a caster wheel. When the sub-unit 20 is detached from the main unit 30, the sub-unit 20 moves relative to the main unit 30 within the room to meet the air conditioning needs of different areas of the room. For example, in areas with a large number of people, or in areas that need fragrance or have odors, it can meet the point-to-point air supply requirements of a certain area, thereby achieving long-distance point-to-point and directional air supply and improving the air treatment effect.

[0117] To improve the efficiency of the fragrance emission of the sub-unit, the sub-unit includes a housing with an air inlet and an air outlet. An air duct is formed inside the housing for airflow, and both the air inlet and the air outlet are connected to the air duct. The air outlet 11b of the fragrance device 10 is also connected to the air duct so that the fragrance of the fragrance device 10 flows into the air duct, thereby achieving the effect that the airflow blown out of the sub-unit carries fragrance.

[0118] Understandably, the air duct formed inside the unit's casing is actually the main air duct for the unit to blow indoor air. The casing has an air inlet and an air outlet, both of which are connected to the air duct. This allows airflow to sequentially pass through the air inlet, air duct, and air outlet to regulate the indoor air. Since the air outlet 11b of the fragrance device 10 is connected to the air duct, when the airflow passes through the duct, a negative pressure is created at the air outlet 11b, thus creating a suction effect on the fragrance device 10. This draws the fragrance into the air duct, and then, through the unit's air outlet, it is blown into the indoor environment along with the supplied airflow.

[0119] In practical applications, the airflow in the duct can be driven by installing a first fan inside the casing. Optionally, the first fan can be installed inside the duct or outside the duct.

[0120] Furthermore, the spice box is located on one side of the air duct, and the side wall of the air duct has an opening. The air outlet 11b is connected to this opening to realize the connection between the spice box and the air duct, thereby achieving the goal of drawing the aroma in the spice box into the air duct through negative pressure drainage.

[0121] In one embodiment of the present invention, the sub-unit is further provided with a mounting base for mounting the fragrance device 10. The mounting base is hollowed out corresponding to both the air inlet 11a and the air outlet 11b. The mounting base is located inside the casing of the sub-unit and is used to mount the fragrance device 10. Optionally, the fragrance device 10 is detachably mounted in the mounting base, and furthermore, the fragrance device 10 is slidably mounted in the mounting box. When the fragrance in one or more fragrance bottles 12 of the fragrance device 10 is used up or deteriorates and needs to be replaced, the fragrance box can be pulled out from the mounting base for replacement; after the fragrance is filled, the fragrance box can be inserted into the mounting base for fixed installation.

[0122] It should be noted that the specific values ​​mentioned above are only for illustrating the implementation of the present invention in detail, and should not be construed as limiting the present invention. In other examples, implementation methods, or embodiments, other values ​​may be selected according to the present invention, and no specific limitations are made here.

[0123] To implement the above embodiments, this invention also proposes a computer-readable storage medium storing a fragrance release control program thereon, which, when executed by a processor, implements the fragrance release control method of any of the above embodiments.

[0124] According to an embodiment of the present invention, a computer-readable storage medium can actively release fragrance corresponding to indoor pollutants when the concentration of indoor pollutants is detected to exceed the standard. Since the fragrance has a pleasant scent and the function of removing pollutants, it can achieve the purpose of timely reminding users and automatically removing indoor pollutants.

[0125] In one example, when the processor executes the fragrance release control program, steps S11 and S13 of the above embodiments can be implemented.

[0126] To achieve the above embodiments, this invention also proposes an air conditioning device that can implement the fragrance release control method of any of the above embodiments. Figure 16 This is a structural block diagram of an air conditioning device according to an embodiment of the present invention. Figure 16 As shown, the air conditioning device 200 proposed in this invention includes a memory 202, a processor 204, and a fragrance release control program 206 stored in the memory 202 and executable on the processor 204. When the processor 204 executes the fragrance release control program 206, it implements the fragrance release control method of any of the above embodiments.

[0127] According to an embodiment of the present invention, the air conditioning device 200 can actively release fragrance corresponding to indoor pollutants when it detects that the concentration of indoor pollutants exceeds the standard. Since the fragrance has a pleasant scent and the function of removing pollutants, it can achieve the purpose of timely reminding users and automatically removing indoor pollutants.

[0128] In one example, when the processor 204 executes the fragrance release control program 206, steps S11 and S13 of the above embodiment can be implemented.

[0129] To achieve the above embodiments, this invention also proposes a fragrance release control device, which can implement the fragrance release control method of any of the above embodiments. Figure 17 This is a structural block diagram of a fragrance release control device according to an embodiment of the present invention. Figure 17 As shown, the fragrance release control device 300 proposed in this invention includes a detection module 302 and a control module 304. The detection module 302 is used to detect the concentration of indoor pollutants; the control module 304 is used to control the release of a fragrance that is compatible with the indoor pollutants when it is determined that the concentration of indoor pollutants exceeds the standard, so as to purify the indoor pollutants while providing a reminder through fragrance release.

[0130] According to the fragrance release control device 300 of the present invention, when the concentration of indoor pollutants exceeds the standard, it can actively release fragrance corresponding to the indoor pollutants. Since the fragrance has a scent and the function of removing pollutants, it can achieve the purpose of timely reminding users and automatically removing indoor pollutants.

[0131] In one embodiment, the fragrance release control device 300 includes a determination module, which determines that the concentration of indoor pollutants exceeds the standard when the concentration of any indoor pollutant is greater than a corresponding preset concentration, provided that there are at least one type of indoor pollutant.

[0132] In one embodiment, the control module 304 includes a calculation unit, a determination unit, and a first control unit. The calculation unit is used to determine the exceedance rate corresponding to each type of indoor pollutant exceeding the standard. The determination unit is used to determine the type of fragrance to be released and the fragrance release logic based on the exceedance rate. The first control unit is used to control the release of the fragrance corresponding to the type of fragrance to be released according to the fragrance release logic.

[0133] In one embodiment, the determining unit includes a first determining subunit and a second determining subunit. The first determining subunit is used to determine the maximum value of the exceedance rate. The second determining subunit is used to determine the type of fragrance to be released based on the indoor pollutants corresponding to the maximum value, and to determine the fragrance release logic based on the maximum value.

[0134] In one embodiment, the first control unit is further configured to determine the air volume and release duration according to the fragrance release logic, and control the release of the fragrance corresponding to the fragrance type to be released according to the air volume, and when the release time reaches the release duration, redetermine the maximum value of the exceedance rate, and adjust the fragrance type to be released and the fragrance release logic according to the redetermined maximum value.

[0135] In one embodiment, the air volume and release duration are positively correlated with the maximum exceedance rate.

[0136] In one embodiment, the formula for calculating the exceedance rate is as follows: a = (A - A0) / A0 * 100%, where a represents the exceedance rate, A represents the concentration of indoor pollutants exceeding the standard, and A0 represents the preset concentration of indoor pollutants exceeding the standard.

[0137] In one embodiment, the types of indoor pollutants include one of particulate matter, formaldehyde, and total volatile organic compounds.

[0138] In one embodiment, the control module 304 further includes a second control unit, a third control unit, and a fourth control unit. The second control unit controls the release of negative ion fragrance when the indoor pollutant is particulate matter. The third control unit controls the release of a first terpene fragrance when the indoor pollutant is formaldehyde. The fourth control unit controls the release of a second terpene fragrance when the indoor pollutant is total volatile organic compounds (TVOCs), wherein the concentration of terpenoids in the first terpene fragrance differs from the concentration of terpenoids in the second terpene fragrance.

[0139] It should be noted that the above explanation of the implementation method and beneficial effects of the fragrance release control method also applies to the computer-readable storage medium, air conditioning device 200 and fragrance release control device 300 of the present invention. To avoid redundancy, they will not be elaborated in detail here.
