[0075] This invention provides an air quality detection system with fragrance function, which can automatically regulate the release rate of fragrance to meet users' needs for precise control of fragrance concentration and improve the user experience.

[0076] Please refer to the following for comprehensive information. Figures 1 to 7 The embodiments of this application provide an air quality detection system with fragrance function, which mainly includes at least an air quality detection device 100.

[0077] The air quality detection device 100 includes at least: an air quality detection module 1, which includes at least a first sensor 11 for detecting the concentration of volatile organic compounds; a fragrance module 2; a fragrance diffuser module 3, which can adjust the release rate of the fragrance module 2; and a controller 4, which is electrically connected to the air quality detection module 1 and the fragrance diffuser module 3, and can control the operating parameters of the fragrance diffuser module 3 based on the detection result of the first sensor 11 to adjust the release rate of the fragrance module 2.

[0078] The air quality detection module 1 is primarily used to detect the concentration of various target substances in the air. Specifically, the air quality detection module 1 may include multiple sensors with different functions. The specific functions and number of these sensors may vary depending on the target substances that the air quality detection module 1 needs to detect, and this application does not impose any specific limitations on them. In order to detect the current concentration of indoor fragrance, the air quality detection module 1 includes at least a first sensor 11 for detecting the concentration of volatile organic compounds (TVOC).

[0079] The fragrance released by the fragrance module 2 evaporates into the indoor air as gaseous molecules, which belong to volatile organic compounds (VOCs). All the measured VOCs are collectively referred to as total volatile organic compounds (TVOCs), which include all CH compounds such as alcohols, aldehydes, benzene, ketones, and alkanes. When the TVOC concentration in the air reaches a certain level, it can be detected by the TVOC sensor.

[0080] In the embodiments of this application, the fragrance module 2 and the first sensor 11 (i.e., the TVOC sensor) are integrated in the air quality detection device 100. Their close proximity facilitates the first sensor 11's rapid determination of the concentration of volatile organic compounds released by the fragrance module 2. Specifically, after acquiring the detection result from the first sensor 11, the controller 4 can process the result. For example, it can calculate the difference between two adjacent TVOC concentrations spaced a certain time apart, i.e., determine the current fragrance release concentration by detecting the increment over a certain period. Of course, the controller 4 can also determine the current fragrance release concentration based on other logic, which is not specifically limited here.

[0081] Furthermore, the air quality detection module 1 may also include at least one of a temperature sensor, a humidity sensor, a formaldehyde sensor, a PM2.5 sensor, and a carbon dioxide sensor. In addition, depending on the application scenario and requirements of the air quality detection module 1, it may also include more types of sensors such as a human body sensor.

[0082] When the air quality detection module 1 is equipped with a temperature sensor, the controller 4 can store the temperature information detected by the sensor. This temperature information can be used as the basis for judgment in the control program that includes temperature conditions. For example, when the temperature exceeds the preset temperature range, the air conditioning system can be activated to automatically adjust the current room temperature to the preset range. In addition, since the temperature information detected by the temperature sensor is generally analog, the controller 4 can also perform digital-to-analog conversion on this temperature information, that is, convert the analog information into digital information to be displayed to the user.

[0083] When the air quality detection module 1 is equipped with a humidity sensor, the controller 4 can store the humidity information detected by the sensor after receiving it. This humidity information can be used as the basis for judgment in the control program that includes humidity conditions. For example, when the humidity exceeds the preset humidity range, a humidifier or dehumidifier can be activated to automatically adjust the current humidity to the preset range. In addition, since the humidity information detected by the humidity sensor is analog, the controller 4 can also perform digital-to-analog conversion on the humidity information, that is, convert the analog information into digital information to be displayed to the user.

[0084] When the air quality detection module 1 is equipped with a formaldehyde sensor, the controller 4 can store the formaldehyde concentration information detected by the sensor after receiving it. This formaldehyde concentration information can be used as the basis for judgment in the control program that includes formaldehyde concentration conditions. For example, when the formaldehyde concentration exceeds the preset safety range, the exhaust equipment (such as an air purifier or fresh air system) can be activated to automatically reduce the current formaldehyde concentration to the preset safety range. In addition, the controller 4 can also perform digital-to-analog conversion on the formaldehyde concentration information, that is, convert analog information into digital information and display it to the user.

[0085] When the air quality detection module 1 is equipped with a PM2.5 sensor, the controller 4 can store the PM2.5 concentration information detected by the sensor after receiving it. This PM2.5 concentration information can be used as the basis for judgment in the control program that includes PM2.5 concentration conditions. For example, when the PM2.5 concentration exceeds the preset safety range, the exhaust equipment (such as an air purifier or fresh air system) can be activated to automatically reduce the current PM2.5 concentration to the preset safety range. In addition, the controller 4 can also perform digital-to-analog conversion on the PM2.5 concentration information, that is, convert analog information into digital information to display to the user.

[0086] When the air quality detection module 1 is equipped with a carbon dioxide sensor, the controller 4 can store the carbon dioxide concentration information detected by the sensor after receiving it. This carbon dioxide concentration information can be used as the basis for judgment in the control program that includes carbon dioxide concentration conditions. For example, when the carbon dioxide concentration exceeds the preset safety range, the exhaust equipment (such as an air purifier or fresh air system) can be activated to automatically reduce the current carbon dioxide concentration to the preset comfortable range. In addition, the controller 4 can also perform digital-to-analog conversion on the carbon dioxide concentration information, that is, convert analog information into digital information and display it to the user.

[0087] The fragrance module 2 includes one or more diffuseable fragrance media. Specifically, the diffuseable fragrance media can be a solid fragrance media or a liquid fragrance media. Furthermore, the specific composition, shape, and structure of the fragrance module 2 can vary depending on the installation space, and this application does not impose specific limitations here. For example, the main structure of the fragrance module 2 may include a volatile aroma stick structure, which may be entirely columnar. Of course, the main structure of the fragrance module 2 is not limited to the examples above, and this application does not impose specific limitations here.

[0088] The aroma diffuser module 3 is used to adjust the release rate of the fragrance module 2. Specifically, the specific form of the aroma diffuser module 3 can vary depending on the different aroma diffuser principles.

[0089] In some specific embodiments, the aroma diffuser module 3 may include any one or a combination of the following: a fan, a heater, an ultrasonic device, or a micro pump.

[0090] When the aroma diffuser module 3 is a fan, the fan can be equipped with a motor. Specifically, the motor is an adjustable-speed motor. When the controller 4 controls the operating parameters of the aroma diffuser module 3 based on the detection results of the first sensor 11 to adjust the release speed of the fragrance module 2, specifically, it can control the working time of the motor, control the speed of the motor, or simultaneously control the working time and speed of the motor, thereby changing the release speed of the fragrance module 2. The release speed of the fragrance module 2 is positively correlated with the working time and speed of the motor. Within a certain range, the longer the working time of the motor and the faster the speed, the faster the release speed of the fragrance module 2.

[0091] When the aroma diffuser module 3 is a heater, and the controller 4 controls the operating parameters of the aroma diffuser module 3 based on the detection result of the first sensor 11 to adjust the release rate of the fragrance module 2, specifically, the temperature of the heater can be adjusted to adjust the release rate of the fragrance module 2. The release rate of the fragrance module 2 is positively correlated with the temperature of the heater. Within a certain range, the higher the temperature of the heater, the faster the release rate of the fragrance module 2.

[0092] When the diffuser module 3 is an ultrasonic device, it uses the principle of high-frequency ultrasonic oscillation to decompose water molecules and soluble plant essential oils into nano-sized cold mist with a diameter of 0.1-5 micrometers, which is then diffused into the air. When the diffuser module 3 is in the form of an ultrasonic device, it effectively protects the activity of essential oil molecules. Simultaneously, the water mist produced by the diffuser module 3 is fine, resulting in a good diffusion effect. In addition, this type of diffuser module 3 can also produce a certain degree of humidification.

[0093] When the aroma diffuser module 3 is a micro-pump, its working principle is as follows: An air pump compresses air at high speed, causing the aromatherapy essential oil to atomize into nano-sized particles and diffuse into the air. During use, only aromatherapy essential oil needs to be added; no water is required, and it is ready to use after connecting to a power source. The nano-atomized ultrafine particles, atomized by the micro-pump, are rapidly and evenly dispersed throughout a wide space like a gas, ensuring a consistent scent without moisture buildup. Compared to traditional aerosol particles, these particles are approximately 1 / 1,000,000 lighter and take 14 hours to fall from a height of 180cm to the ground, thus maintaining the fragrance in the space for a long time. When the aroma diffuser module 3 is a micro-pump, it ensures the fragrance quality and eliminates any unpleasant odors during the diffusion process. Furthermore, when the aroma diffuser module 3 is a micro-pump, it can intelligently adjust the fragrance concentration, spray frequency, and working time, making it the most ideal type of device for aroma diffusion currently available.

[0094] The controller 4 can be electrically connected to the air quality detection module 1 and the fragrance diffuser module 3. The controller 4 can control the operating parameters of the fragrance diffuser module 3 based on the detection results of the first sensor 11, so as to adjust the release rate of the fragrance module 2.

[0095] Specifically, the controller 4 can be in the form of a microcontroller unit (MCU), also known as a single-chip microcomputer or microcontroller. Of course, the controller 4 can also be in other forms, and this application does not impose any specific limitations on it. The controller 4 can be electrically connected to the air quality detection module 1 and the aroma diffuser module 3 via signal lines. Of course, the controller 4 can also be electrically connected via other wired or wireless methods. This application does not impose any limitations on the specific method of signal transmission between the controller 4 and other functional components.

[0096] When the controller 4 controls the operating parameters of the aroma diffuser module 3 based on the detection results of the first sensor 11, the operating parameters controlled vary depending on the type of aroma diffuser module 3.

[0097] In one embodiment, when the fragrance diffuser module 3 is a fan, the fan is equipped with a motor, and the controller 4 stores the correspondence between the rotation speed of the motor and the release speed of the fragrance module 2. The controller 4 controls the rotation speed of the motor based on the correspondence to adjust the release speed of the fragrance module 2.

[0098] In this embodiment, the aroma diffuser module 3 is described using a fan as an example. Other types of aroma diffuser modules 3 can be described by analogy to this embodiment, and will not be described in detail here.

[0099] When the aroma diffuser module 3 is a fan, the fan is equipped with a motor with adjustable speed. The higher the speed of the motor, the faster the aroma diffuser module 2 releases fragrance. The controller 4 can pre-store the correspondence between the motor speed and the release speed of the aroma diffuser module 2.

[0100] After receiving the detection result from the first sensor 11, the controller 4 can identify the current concentration of volatile organic compounds. The controller 4 can compare the currently identified concentration of volatile organic compounds with the target concentration, and then determine whether the operating parameters of the fragrance diffuser module 3 (e.g., the motor speed) need to be adjusted based on the comparison result. If adjustment is needed, the controller 4 controls the motor speed based on the correspondence until the user's fragrance concentration needs are accurately met.

[0101] In this embodiment, the air quality detection device 100 of the air quality detection system integrates air quality detection and fragrance functions. In particular, it is configured with: a fragrance module 2, a fragrance diffusion module 3, an air quality detection module 1 including at least a first sensor 11 for detecting the concentration of volatile organic compounds, and a controller 4. The controller 4 can control the operating parameters of the fragrance diffusion module 3 based on the detection results of the first sensor 11, and adjust the release rate of the fragrance module 2. In other words, the air quality detection system provided by this application can adjust the release rate of the fragrance module 2 according to the user's different needs for fragrance concentration, thereby accurately controlling the fragrance release concentration and meeting the personalized and differentiated needs of users for fragrance concentration in different scenarios, thus better ensuring the user experience.

[0102] Please refer to the following: Figure 7 In one embodiment, the air quality detection system with fragrance function may further include an air circulation device 200 that is communicatively connected to the controller 4, and the controller 4 controls the air circulation device 200 to work according to the detection result of the first sensor 11.

[0103] In this embodiment, the air quality detection system with fragrance function may include an air circulation device 200 communicatively connected to the controller 4. The controller 4 may be integrated into the air quality detection device 100, or it may be set up independently, or it may be located in the cloud 400. Figure 7 As shown, taking the controller 4 as an example when set up independently, it can communicate with the air quality detection device 100 and the air circulation device 200 via wired / wireless means. When the controller 4 is set up in the cloud 400, it can communicate with the air quality detection device 100 and the air circulation device 200 via wireless connection (e.g., WIFI).

[0104] When the air quality detection system with fragrance function also includes an air circulation device 200, the air circulation device 200 can make the fragrance diffuse more evenly and quickly. For example, when the first sensor 11 detects that the current fragrance concentration is low and the difference from the target concentration is large, the air circulation device 200 can be activated.

[0105] Specifically, the air circulation device 200 may include any one or a combination of the following: an air conditioner, a triple air supply coil, or a variable air volume (VAV) air conditioning system. The air conditioner, triple air supply coil, and VAV air conditioning system, once activated, can all improve the diffusion speed and uniformity of the fragrance. Of course, the air circulation device 200 can also take other forms. It is not limited to the above description; those skilled in the art, guided by the technical essence of this application, may make other modifications, but as long as their functions and effects are the same as or similar to those of this application, they should be covered within the scope of protection of this application.

[0106] Please refer to the following: Figure 7 In one embodiment, the air quality detection system with fragrance function may further include: a linkage exhaust device 300 that is communicatively connected to the controller 4, wherein the controller 4 controls the linkage exhaust device 300 to work according to the detection result of the first sensor 11.

[0107] In this embodiment, the air quality detection system with fragrance function may include a linkage exhaust device 300 that is communicatively connected to the controller 4. The controller 4 can be integrated into the air quality detection device 100, or it can be set up independently, or it can be located in the cloud 400. Figure 7 As shown, taking the controller 4 as an example when set up independently, it can communicate with the air quality detection device 100 and the linked exhaust device 300 via wired / wireless means. When the controller 4 is set up in the cloud 400, it can communicate with the air quality detection device 100 and the linked exhaust device 300 via wireless connection (such as WIFI).

[0108] When the air quality detection system with fragrance function also includes a linked exhaust device 300, the linked exhaust device 300 can be used to quickly remove the fragrance. For example, when the first sensor 11 detects that the current fragrance concentration is high and exceeds a certain limit, the linked exhaust device 300 can be activated. In addition, if the user feels that the current fragrance does not smell good, or wants to change the fragrance, the linked exhaust device 300 can also be activated to quickly remove the fragrance.

[0109] Specifically, the linked exhaust device 300 may include any one or a combination of the following: a range hood, a fresh air system, a bathroom heater, and an air purifier. Once activated, the range hood, fresh air system, bathroom heater, and air purifier can all increase the speed at which fragrance is expelled. Of course, the linked exhaust device 300 can also take other forms. It is not limited to the above description; those skilled in the art, guided by the technical essence of this application, may make other modifications, but as long as the functions and effects achieved are the same as or similar to those of this application, they should all be covered within the scope of protection of this application.

[0110] like Figure 1 As shown, in one embodiment, the air quality detection device 100 may further include a power supply module 5, which can supply power to the aroma diffuser module 3, the air quality detection module 1 and the controller 4.

[0111] Specifically, the power supply module 5 can be connected to the air quality detection module 1 via a power harness to supply power to the air quality detection module 1; the power supply module 5 can also be connected to the controller 4 via a power harness to supply power to the controller 4; in addition, the power supply module 5 can also be connected to the aroma diffuser module 3 via a power harness to supply power to the aroma diffuser module 3. Of course, besides connecting the power supply module 5 to the various functional modules to be powered via power harnesses, it can also be connected in other ways, such as through circuit board integration. This application does not specifically limit the connection method between the power supply module 5 and other functional modules.

[0112] The power supply module 5 can be a DC power supply, an AC power supply, or a combination of both. When the power supply module 5 is a DC power supply, it can include a mounting base in which a rechargeable battery or a regular battery can be installed. When the power supply module 5 is an AC power supply, the AC power supply can include an AC-DC converter module for converting 220V AC power into a predetermined DC power.

[0113] like Figure 1 As shown, in one embodiment, the air quality detection device 100 further includes a control valve 6 electrically connected to the power supply module 5 and the aroma diffuser module 3, and the controller 4 is communicatively connected to the control valve 6. The controller 4 can control the control valve 6 according to the detection result of the first sensor 11.

[0114] In this embodiment, the control valve 6 can be installed on the power supply line between the power supply module 5 and the aroma diffuser module 3 to control the electrical connection between them. For example, when the control valve 6 is closed, the power supply module 5 is electrically connected to the aroma diffuser module 3, and the power supply module 5 can supply power to the aroma diffuser module 3; when the control valve 6 is open, the power supply module 5 no longer supplies power to the aroma diffuser module 3. In specific control, the controller 4 can obtain the current concentration of volatile organic compounds (VOCs) in the indoor environment through the first sensor 11. When the VOC concentration meets certain conditions (e.g., close to or reaching a target concentration threshold), it indicates that the current aroma diffuser demand can meet the user's fragrance concentration requirements. At this time, the controller 4 can control the control valve 6 to switch from a closed state to an open state. When the VOC concentration is low (e.g., below a minimum concentration threshold), it indicates that there is a current aroma diffuser demand. The controller 4 can control the control valve 6 to automatically switch from an open state to a closed state, so that the aroma diffuser module 3 is powered on for aroma diffuser operation. Furthermore, the state switching triggering conditions of the control valve 6 are not limited to the examples mentioned above.

[0115] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In one embodiment, the air quality detection device 100 further includes a first housing 71 and a second housing 72, the air quality detection module 1 is disposed in the first housing 71, the fragrance module 2 is disposed in the second housing 72, and the first housing 71 and the second housing 72 are detachably connected.

[0116] In this embodiment, the air quality detection device 100 may include a detachably connected first housing 71 and a second housing 72. The first housing 71 may house an air quality detection module 1. Furthermore, a controller 4, a power supply module 5, a control valve 6, etc., may also be housed within the first housing 71. The second housing 72 may house a fragrance module 2. The fragrance diffuser module 3 may be housed either within the first housing 71 or the second housing 72. Specifically, the shape and structure of the first housing 71 and the second housing 72 may vary depending on the type of internally installed components, the requirements of the installation environment, and aesthetic requirements; therefore, this application does not impose specific limitations.

[0117] In this embodiment, the first housing 71 and the second housing 72 are detachably connected. Specifically, the first housing 71 is provided with a first mating part 710, and the second housing 72 is provided with a second mating part 720. The first mating part 710 and the second mating part 720 cooperate to form a detachable connection structure. The detachable connection can be any one of a snap-fit ​​connection, a threaded connection, or a magnetic connection. Of course, the detachable connection can also be in other ways and is not limited to the above description. Those skilled in the art, inspired by the technical essence of this application, may make other modifications, but as long as the achieved function and effect are the same as or similar to that of this application, they should all be covered within the scope of protection of this application.

[0118] In one specific embodiment, both the first mating part 710 and the second mating part 720 can be magnetic contacts, and electrical connection can be achieved when the first mating part 710 and the second mating part 720 come into contact.

[0119] In this embodiment, the detachable connection between the first housing 71 and the second housing 72 can specifically be a magnetic connection. Both the first mating part 710 and the second mating part 720 can be magnetic contacts. To ensure the reliability of the magnetic attraction and the convenience of user operation, one magnetic contact can be provided with a protrusion, and the other with a recess. For example, the first mating part 710 can be at least one recess, and the second mating part 720 can be at least one protrusion. When the second housing 72 mates with the first housing 71, the protrusion inserts into the recess, thus achieving the mating connection of the two housings.

[0120] The electrical connection achieved after the first mating part 710 and the second mating part 720 come into contact can be specifically achieved as follows: the first mating part 710 is a contact provided on the first housing 71, which is connected to the power source via a power cord. The second mating part 720 is a contact provided on the second housing 72, which can be connected to the fragrance diffuser module 3 via a power cord. To ensure the reliability and stability of the connection, there can be multiple contacts, for example, two, three, four, or even more. The specific number of contacts is not specifically limited herein.

[0121] When the first mating part 710 and the second mating part 720 are mated, the two contacts make contact to achieve an electrical connection between the power lines.

[0122] Of course, the first mating part 710 and the second mating part 720 may take other forms and are not limited to the above description. Those skilled in the art may make other changes based on the technical essence of this application, but as long as the functions and effects they achieve are the same as or similar to those of this application, they should be covered within the scope of protection of this application.

[0123] like Figure 4 As shown, in one embodiment, the first mating part 710 may include multiple sets, and the multiple sets of first mating parts 710 are disposed at different positions of the first housing 71.

[0124] In this embodiment, the first mating part 710 may include multiple sets, thereby providing a variety of different mounting positions for the second housing 72.

[0125] Specifically, the first housing 71 may be in the shape of a box with a certain thickness. The first housing 71 includes a first surface and a second surface opposite to each other along the thickness direction, and a side surface surrounding the first surface and the second surface. The second housing 72 is connected to the side surface.

[0126] For example, the sides of the first housing 71 may include a first side, a second side, a third side, and a fourth side disposed opposite to each other. Wherein, if the air quality detection device 100 conforms to... Figure 4 When installed in the indicated orientation, the first mating part 710 can be provided on the other three sides (the first, second, and third sides) except for the fourth side located at the bottom. When the second housing 72 is paired with the first housing 71, the user can install it according to their needs, thus ensuring installation flexibility. In addition, the user can install multiple second housings 72 at the same time, so that multiple fragrances can be used in combination.

[0127] The second housing 72 can also be a hollow box shape, and the surfaces of the second housing 72 that mate with the first housing 71 can be fitted together. The second housing 72 may be provided with a diffuser 74, which allows fragrance to diffuse outwards. The specific number, position, and shape of the diffuser 74 are not specifically limited herein. Figure 4 As shown, the second housing 72 can be a hollow rectangular body, and a plurality of aroma diffusers 74 can be provided at one end of the rectangular body.

[0128] Please refer to the following: Figure 5 The air quality detection device 100 may further include a housing 7, and the air quality detection module 1 and the fragrance module 2 are disposed within the housing 7.

[0129] In this embodiment, the air quality detection module 1 and the fragrance module 2 are disposed inside the housing 7. Since the air quality detection module 1 includes at least a first sensor 11 for detecting the concentration of volatile organic compounds, the concentration of volatile organic compounds in the current environment can be detected by the first sensor 11. In particular, after the first sensor 11 and the fragrance module 2 are integrated into the housing 7 of the same device, the fragrance concentration released by the fragrance module 2 can be obtained quickly and accurately by the first sensor 11.

[0130] like Figure 5 As shown, in one specific embodiment, the housing 7 has an opening 701 at a first position, and the fragrance module 2 is disposed in the opening 701 in a detachable manner.

[0131] In this embodiment, the housing 7 is a box-shaped structure with a certain thickness. The housing 7 includes a first surface and a second surface disposed opposite to each other along the thickness direction, and a side surface surrounding the first surface and the second surface. Of course, the shape of the housing 7 is not limited to the above example, and those skilled in the art may make other modifications based on the technical essence of this application.

[0132] At least the first surface of the housing 7 has an air hole 73 for air circulation, which facilitates the detection of pollutant concentration in the ambient air by the sensor inside the housing 7. Of course, in addition to the first surface, air holes 73 can also be provided at other locations on the housing 7, such as the second surface. The first location with the opening 701 can be located on the side of the housing 7.

[0133] The housing 7 is detachably connected to the fragrance module 2 at the opening 701, facilitating the replacement of the fragrance module 2 and meeting the user's personalized fragrance needs. The detachable connection can be achieved through threaded connection, snap-fit ​​connection, or magnetic connection. Of course, other methods are also possible. This is not limited to the above description; those skilled in the art may make other modifications based on the technical essence of this application, but any modifications that achieve the same or similar functions and effects as those in this application should be included within the scope of protection of this application.

[0134] Taking a threaded connection as an example of the detachable connection method, when the opening 701 of the housing 7 is connected to the fragrance module 2 by a thread, an internal thread can be provided at the opening 701, and a connecting part 22 can be provided at one end of the fragrance module 2. The connecting part 22 includes an external thread that matches the internal thread. An operating part 21 can be provided at the end of the fragrance module 2, and the fragrance module 2 can be installed or removed by rotating the operating part 21.

[0135] like Figure 5 The operating part 21 may have multiple aroma diffusers 74 in its center, through which the fragrance can diffuse outward. The specific number, location, and shape of the aroma diffusers 74 are not specifically limited herein.

[0136] like Figure 6 As shown, in one specific embodiment, the first housing 71 is a box-shaped structure with a certain thickness. The first housing 71 includes a first surface and a second surface opposite to each other along the thickness direction, and a side surface surrounding the first surface and the second surface. At least the first surface has an annular vent 73, and the second housing 72 is connected to the middle of the annular vent 73.

[0137] In this embodiment, the first housing 71 can be a hollow box shape, comprising a first surface and a second surface opposite each other along the thickness direction, and a side surface surrounding the first surface and the second surface. At least one surface of the first housing 71 (e.g., the surface in an unobstructed state after installation) may have an air hole 73. Specifically, the air hole 73 may be annular, and an opening 701 for mounting the second housing 72 may begin at the center of the annular air hole 73. The second housing 72 can be detachably mounted on the first housing 71 at the opening 701. This detachable connection may include any one of a snap-fit ​​connection, a threaded connection, or a magnetic connection. Further details are omitted here.

[0138] Please refer to the following: Figure 8 Based on the air quality detection system with fragrance function provided in the above embodiments, this application also provides a control method for the air quality detection system with fragrance function.

[0139] The air quality detection system with fragrance function mainly includes: an air quality detection module 1, a fragrance module 2, a fragrance diffusion module 3, and a controller 4, which at least include a first sensor 11 for detecting the concentration of volatile organic compounds. The specific functions, composition, structure, and connection relationships of the air quality detection module 1, fragrance module 2, fragrance diffusion module 3, and controller 4 can be found in the detailed description of the above-described implementation of the air quality detection system with fragrance function, and will not be elaborated further here.

[0140] The control method for this air quality detection system with fragrance function may include the following steps:

[0141] Step S10: The controller 4 receives the detection result representing the concentration of volatile organic compounds detected by the first sensor 11;

[0142] Step S11: Based on the received detection result of the volatile organic compound concentration, the controller 4 adjusts the operating parameters of the fragrance module 3 to control the release rate of the fragrance module 2.

[0143] After receiving the detection result from the first sensor 11, the controller 4 can identify the current concentration of volatile organic compounds. The controller 4 can compare the currently identified concentration of volatile organic compounds with the target concentration, and then determine whether the operating parameters of the fragrance diffuser module 3 (e.g., the motor speed) need to be adjusted based on the comparison result. If it is determined that the operation of the fragrance diffuser module 3 needs to be adjusted, the operating parameters of the fragrance diffuser module 3 can be adjusted to control the release rate of the fragrance module 2.

[0144] The controller 4 can store the correspondence between the working parameters of the fragrance module 3 and the release rate of the fragrance module 2. Specifically, the controller 4 can control the working parameters of the fragrance module 3 based on the stored correspondence, thereby adjusting the release rate of the fragrance module 2 and accurately meeting the user's needs for the concentration of volatile organic compounds.

[0145] In one embodiment, when the aroma diffuser module 3 is a fan with a motor, the controller 4 stores the correspondence between the motor speed and the release speed of the aroma module 2. The controller 4 controls the motor speed based on the correspondence to adjust the release speed of the aroma module 2.

[0146] In this specification, the diffuser module 3 is mainly used as an example of a fan. Other types of diffuser modules 3 can be compared with this form, and will not be described in detail here.

[0147] When the fragrance diffuser module 3 is a fan, the concentration of fragrance release is controlled by adjusting the fan motor speed. The controller 4 can store multiple parallel control logics. When performing control functions, the controller 4 can call the corresponding control logic.

[0148] If the current concentration of volatile organic compounds is less than the target concentration and there is a large first difference between the two, the speed of the motor can be increased so that the motor runs at a larger first speed, thereby increasing the release speed of the fragrance module 2 and making the current indoor concentration of volatile organic compounds quickly approach the target concentration.

[0149] The target concentration can be pre-stored in controller 4 or set based on the current user's needs. The target concentration can be a single concentration value or a concentration range. The first difference can also be pre-stored in controller 4. This first difference can be a concentration difference or a preset floating range.

[0150] The air quality detection device 100 can be set with multiple modes to meet different user needs, such as a first mode with a high target concentration, a second mode with a medium target concentration, and a third mode with a low target concentration. Different target concentrations can be stored for each mode. When a user selects a mode, the data stored in that mode is retrieved.

[0151] After the motor has been running at the first speed for a period of time, the current concentration of volatile organic compounds has been effectively increased and may have approached the target concentration in the current mode. For example, if the difference between the current concentration of volatile organic compounds and the target concentration is less than the first difference, the motor speed can be reduced or the motor can be turned off directly.

[0152] Of course, before the difference between the current volatile organic compound concentration and the target concentration is less than the first difference, the controller 4 can also control the release rate of the fragrance module 2 based on the stored correspondence. For example, it can detect the current volatile organic compound concentration in real time or periodically, and control the current motor to run at a speed corresponding to the current volatile organic compound concentration based on the stored correspondence.

[0153] Overall, the air quality detection system provided in this application can adjust the release rate of the fragrance module 2 according to the user's different needs for fragrance concentration during operation, thereby accurately controlling the fragrance release concentration, meeting the personalized and differentiated needs of users for fragrance concentration in different scenarios, and thus better ensuring the user experience.

[0154] In one embodiment, the air quality detection device 100 may further include: a power supply module 5, and a control valve 6 electrically connected to the power supply module 5 and the aroma diffuser module 3. The power supply module 5 and the control valve 6 can be found in the detailed description of the above-described air quality detection system embodiments, and will not be elaborated upon further here.

[0155] The control method may further include: when the concentration of volatile organic compounds is lower than a first concentration threshold, controlling the control valve 6 to switch from an open state to a closed state; or, when the concentration of volatile organic compounds is higher than a second concentration threshold, controlling the control valve 6 to switch from a closed state to an open state.

[0156] The first and second concentration thresholds can be stored in preset concentrations in the controller 4, where the first and second concentration thresholds can be boundary values ​​of volatile organic compound (VOC) concentration when the aroma diffuser module 3 is activated. Specifically, the first concentration threshold can be the minimum VOC concentration value when the aroma diffuser module 3 is operating; the second concentration threshold can be the maximum VOC concentration value when the aroma diffuser module 3 is operating.

[0157] When the current concentration of volatile organic compounds detected by the first sensor 11 is lower than the first concentration threshold, the controller 4 can switch the control valve 6 from the open state to the closed state to start the aroma diffuser module 3.

[0158] When the current concentration of volatile organic compounds detected by the first sensor 11 is higher than the second concentration threshold, the controller 4 can switch the control valve 6 from a closed state to an open state.

[0159] In one embodiment, the air quality detection system with fragrance function further includes a linkage exhaust device 300 communicatively connected to the controller 4. The linkage exhaust device 300 can be found in the detailed description of the above-described air quality detection system implementation, and will not be elaborated upon here.

[0160] The control method may further include: activating the linkage exhaust device 300 when the concentration of volatile organic compounds is higher than the third concentration threshold.

[0161] In this embodiment, a maximum concentration of volatile organic compounds (VOCs), i.e., a third concentration threshold, can be pre-stored in the controller 4. Once the current VOC concentration is detected to have reached this third concentration threshold, the linked exhaust device 300 can be activated to quickly reduce the concentration of the fragrance, thereby ensuring the safety of the indoor environment. This third concentration threshold can be greater than the second concentration threshold, serving as a safety threshold set for abnormal operating conditions.

[0162] Alternatively, the control method may further include: activating the linkage ventilation device 300 when a user's fragrance deodorization request is detected.

[0163] This air quality detection system with fragrance function can have a rapid fragrance removal mode. Specifically, a trigger button can be set on the housing 7, or the user can activate the rapid fragrance removal mode via remote control, mobile terminal APP, etc. When the user does not need the fragrance, or does not like the current fragrance and needs to change the fragrance type, they can activate the rapid fragrance removal mode to quickly remove the fragrance from the current indoor environment.

[0164] In one embodiment, the air quality detection system with fragrance function may further include an air circulation device 200 communicatively connected to the controller 4. The air circulation device 200 can be found in the detailed description of the above-described air quality detection system embodiments, and will not be elaborated upon here.

[0165] The control method may further include: activating the air circulation device 200 when the concentration of volatile organic compounds is lower than the fourth concentration threshold.

[0166] In this embodiment, the air circulation device 200 can be activated simultaneously with the fragrance diffusion module 3. Furthermore, after the fragrance diffusion module 3 has been activated for a certain period, if the first sensor 11 detects that the current concentration of volatile organic compounds has not yet reached the ideal concentration (e.g., below the fourth concentration threshold), or that the concentration diffusion within the area is uneven (e.g., a large concentration difference between the first and second areas of the room), the air circulation device 200 can be activated to achieve rapid and uniform release of fragrance. The fourth concentration threshold can be a concentration value between the first and second concentration thresholds.

[0167] Please refer to the following: Figure 9 Based on the air quality detection system with fragrance function provided in the above embodiments, this application also provides a control method for the air quality detection system with fragrance function.

[0168] The air quality detection system with fragrance function may include: an air quality detection module 1, a fragrance module 2, a fragrance diffuser module 3, a controller 4, a power supply module 5, a control valve 6, a linked exhaust device 300, and an air circulation device 200. The specific functions, composition, structure, and connection relationships of the air quality detection module 1, fragrance module 2, fragrance diffuser module 3, controller 4, power supply module 5, control valve 6, linked exhaust device 300, and air circulation device 200 can be referred to the detailed description of the above-described implementation of the air quality detection system with fragrance function, and will not be elaborated further here.

[0169] The control method may include the following steps:

[0170] Step S21: Identify the user's fragrance needs signals;

[0171] Step S22: After obtaining the user's fragrance demand signal, switch the control valve 6 from the open state to the closed state and start the fragrance diffusion module 3;

[0172] Step S23: Receive the detection result representing the concentration of volatile organic compounds detected by the first sensor 11;

[0173] Step S24: Based on the received detection result of the volatile organic compound concentration, the controller 4 adjusts the operating parameters of the aroma diffuser module to control the release concentration of the aroma diffuser module;

[0174] Step S25: Compare the currently received volatile organic compound concentration with a preset value, and control the working state of at least one of the control valve 6, the linkage exhaust device 300, and the air circulation device 200 according to the comparison result.

[0175] Taking a specific scenario as an example, when a user needs to release fragrance, the air quality detection device 100 can be activated. The controller 4 stores multiple operating modes, each corresponding to a preset value for the concentration of volatile organic compounds (VOCs). For each operating mode, a trigger button can be provided on the housing 7 of the air quality detection device 100. The user can select and trigger the corresponding button according to their current needs. Of course, the user can also activate the air quality detection device 100 in other ways, such as by operating a remote control or a mobile app; specific methods are not limited here.

[0176] When the user starts the air quality detection device 100, the controller 4 can recognize that the user has a need to use fragrance. At this time, the control valve 6 can be switched from the open state to the closed state to start the fragrance diffusion module 3 and diffuse the fragrance.

[0177] During the diffusion process, the first sensor 11 can continuously or periodically detect the current concentration of volatile organic compounds (VOCs). The controller 4 can compare the current VOC concentration with a preset value and control the corresponding components based on the comparison result. For example, when the VOC concentration is higher than a second concentration threshold, the control valve 6 is switched from a closed state to an open state, shutting down the diffusion module 3. If the current indoor VOC concentration exceeds the second concentration threshold after diffusion is initiated by turning on the diffusion module 3, the diffusion module 3 can be shut down first. After a period of time, if the VOC concentration is lower than the first concentration threshold, the control valve 6 can be switched from an open state to a closed state, and the diffusion module 3 can be restarted for diffusion. By monitoring the current VOC concentration, the working state and parameters of the diffusion module 3 can be automatically controlled, ensuring that the current indoor VOC concentration is within a preset range, thus meeting the user's personalized needs for fragrance concentration.

[0178] In addition, when the concentration of the volatile organic compounds is higher than the third concentration threshold, the linkage exhaust device 300 is activated.

[0179] In this embodiment, a maximum concentration of volatile organic compounds (VOCs), i.e., a third concentration threshold, can be pre-stored in the controller 4. Once the current VOC concentration is detected to have reached this third concentration threshold, the linked exhaust device 300 can be activated to quickly reduce the concentration of the fragrance, thereby ensuring the safety of the indoor environment. This third concentration threshold can be greater than the second concentration threshold, serving as a safety threshold set for abnormal operating conditions.

[0180] Alternatively, the control method may further include: activating the linkage ventilation device 300 when a user's fragrance deodorization request is detected.

[0181] This air quality detection system with fragrance function can have a rapid fragrance removal mode. Specifically, a trigger button can be set on the housing 7, or the user can activate the rapid fragrance removal mode via remote control, mobile terminal APP, etc. When the user does not need the fragrance, or does not like the current fragrance and needs to change the fragrance type, they can activate the rapid fragrance removal mode to quickly remove the fragrance from the current indoor environment.

[0182] When the concentration of volatile organic compounds is lower than the fourth concentration threshold, the air circulation device 200 is activated.

[0183] After the fragrance diffusion module 3 has been activated for a certain period of time, if the first sensor 11 detects that the current concentration of volatile organic compounds has not yet reached the ideal concentration, for example, it is below the fourth concentration threshold; or the concentration diffusion within the area is uneven, for example, the concentration difference between the first area and the second area in the room is large, then the air circulation device 200 can be activated to achieve the purpose of quickly and evenly releasing the fragrance. The fourth concentration threshold can be a concentration value between the first concentration threshold and the second concentration threshold.

[0184] It should be noted that in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.
