[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the following further details the present application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] The air purification method provided by the embodiments of the present application can be applied to an air purification system as shown in Figure 1 The air purification system can be applied to various leisure and entertainment places, which usually have characteristics such as relatively enclosed space, dense personnel, and frequent activities. Specifically, it can be a public entertainment place or a private family place, such as KTV, restaurant, chess and card room, cinema, and game room, etc. The air purification system provided by the embodiments of the present application can circulate and purify the indoor air in the space environment of such places.

[0046] Exemplarily, the air purification system may include a controller 110, a fresh air device 120, a purification device 130, and a data acquisition component 140 connected to the controller 110. The data acquisition component 140 is used to acquire indoor environmental data and usage status data. The controller 110 is used to control the operation of the fresh air device 120 and the purification device 130 according to the air purification method provided in the embodiments of the present application, and perform cyclic purification processing on the indoor air in the target space. The data storage system can store the data that the controller 110 needs to process. The data storage system can be integrated on the controller 110, or can be placed on the cloud or other network servers.

[0047] Specifically, after the controller 110 detects that the target space is enabled, it can obtain the indoor environmental data corresponding to the target space through the data acquisition component 140, and determine whether the ventilation condition is met according to the indoor environmental data, so as to perform internal circulation processing or external circulation processing on the indoor air in the target space by operating the fresh air device 120 and the purification device 130; then continuously obtain the usage status data in the target space through the data acquisition component 140, and when the usage status data meets the re-ventilation condition, perform external circulation processing on the indoor air in the target space by operating the fresh air device 120 and the purification device 130.

[0048] Among them, the controller 110 can be a control chip or a control circuit board set in the target space, etc., or can be an external control system implemented based on wireless communication. The external control system can be implemented through devices such as terminals or servers. The terminal can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0049] In an exemplary embodiment, as Figure 2 shown, an air purification method is provided. Taking the method applied to the Figure 1 controller 110 as an example, it includes the following steps 200 to step 800. Among them:

[0050] Step 200, after detecting that the target space is enabled, obtain the indoor environmental data corresponding to the target space.

[0051] Among them, the air purification system can be set in a certain leisure and entertainment venue, which can include several enclosed indoor spaces. The air purification system can be used to circulate and purify the indoor air of these indoor spaces. Each indoor space can include its corresponding fresh air device, purification device, and data acquisition component, and is connected to the controller of the air purification system to achieve the control of these devices. The controller can be set uniformly, or a corresponding controller can be set in each indoor space.

[0052] Specifically, the target space is the space used by users among several indoor spaces. Taking several box spaces set in a KTV as an example of indoor spaces, the target space can refer to the box where users enter to sing. Correspondingly, detecting that the target space is enabled means detecting that the indoor space is used by users.

[0053] Exemplarily, detecting whether the target space is enabled can be achieved by detecting whether there are people entering the target space, or by detecting whether the devices in the target space are started, or by detecting whether the volume data in the target space exceeds the low volume threshold, where the low volume threshold represents the volume threshold for the presence of human activities. Correspondingly, the implementation means of the above detection process can be obtained by judging based on the corresponding data collected by the data acquisition components set in the indoor space or the devices. The data acquisition components can correspondingly include various sensors, such as infrared detectors, infrared thermal imagers, radar detectors, audio detectors, volume sensors, and human presence sensors, etc.

[0054] Furthermore, after detecting that the target space is enabled, it is necessary to timely obtain the indoor environment data corresponding to the target space for judging whether it is necessary to circulate and purify the indoor air. Among them, the indoor environment data represents the air quality situation of the target space in the current state or about to change to, and can be used to judge whether it is necessary to circulate and purify the indoor air, and what type of circulation purification is required for the indoor air.

[0055] It can be understood that in order to achieve different judgment purposes, the data types included in the indoor environment data can be various.

[0056] Exemplarily, if the indoor environmental data represents the air quality in the target space under the current state, the indoor environmental data may include physical, chemical, and biological index data under the current state. For example, it may include physical index data such as temperature, humidity, and air velocity, and may also include chemical index data such as formaldehyde, total volatile organic compounds (TVOC), carbon monoxide (CO), carbon dioxide (CO2), PM10, PM2.5, sulfur dioxide (SO2), and nitrogen dioxide (NO2). It may also be microbial index data such as bacteria and fungi. If the indoor environmental data represents the air quality that the target space is about to change to, it may include the number of indoor people in the target space. It can be understood that if there are too many indoor people, in a closed and small space like the target space, the air does not circulate, and with chatting, singing, and breathing, the air quality is very likely to decline rapidly.

[0057] Correspondingly, different types of indoor environmental data can be collected based on data collection components set in the indoor space. Furthermore, the data collection components may include sensors for collecting the above various types of data. For example, it may include temperature and humidity sensors, PM2.5 sensors, and PM10 sensors, etc., and may also include infrared people counters, ultrasonic people counters, and intelligent cameras, etc.

[0058] Step 400, determine whether the ventilation condition is met according to the indoor environmental data, and perform internal circulation processing or external circulation processing on the indoor air in the target space.

[0059] It can be understood that generally, before the target space is enabled, the air purification system is in an unoperated state, and the air quality cannot be ensured to be up to standard. Furthermore, after the target space is enabled, that is, when users start to enter the target space, it is necessary to control the air purification system to start running and perform circulation processing on the indoor air in the target space, which can be internal circulation processing or external circulation processing.

[0060] Specifically, whether the ventilation condition is met is characterized by whether ventilation processing needs to be performed on the target space, that is, it can be directly understood as whether external circulation processing needs to be performed on the indoor air in the target space. It can be understood that when it is determined that the ventilation condition is not met, internal circulation processing needs to be performed on the indoor air in the target space; when it is determined that the ventilation condition is met, external circulation processing needs to be performed on the indoor air in the target space.

[0061] Further, if the indoor environmental data represents the air quality in the target space under the current state, determining whether the ventilation condition is met based on the indoor environmental data may be that the air quality in the target space under the current state belongs to a pollution situation above medium. Relying solely on the method of performing internal circulation processing on the indoor air in the target space cannot improve the air quality in the target space in a short time. Therefore, it is determined that the ventilation condition is met, and external circulation processing needs to be performed on the indoor air in the target space to deliver fresh outdoor air into the target space and quickly improve the air quality in the target space.

[0062] If the indoor environmental data represents the air quality that the target space is about to change to, determining whether the ventilation condition is met based on the indoor environmental data may be that the number of indoor people in the target space exceeds a certain number. As people move, the air quality is very likely to drop rapidly. Therefore, it is determined that the ventilation condition is met, and external circulation processing needs to be performed on the indoor air in the target space to deliver fresh outdoor air into the target space and ensure that the air quality does not drop rapidly.

[0063] It can be understood that based on the fresh air device and purification device included in the air purification system, the implementation means of the above internal circulation processing and external circulation processing can be achieved by controlling the above devices to be in different operating states.

[0064] Exemplarily, performing internal circulation processing on the indoor air in the target space includes: controlling the purification device in the target space to start running.

[0065] Specifically, internal circulation processing means that air circulates in a closed space without exchanging with the outside air. Therefore, to perform internal circulation processing, it is only necessary to control the purification device to start running. After controlling the purification device to start running, the process of performing internal circulation processing on the indoor air in the target space may further include controlling the running duration of the purification device.

[0066] Exemplarily, performing external circulation processing on the indoor air in the target space includes: controlling the fresh air device in the target space to start running, or controlling the fresh air device and the purification device in the target space to start running.

[0067] Specifically, external circulation processing means that both the internal and external air ducts are flowing, and internal and external air can be exchanged. Therefore, to perform external circulation processing, it can be to only control the fresh air device to start running, or to control the fresh air device and the purification device to run synchronously. Similarly, after controlling the fresh air device and the purification device to start running, the process of performing external circulation processing on the indoor air in the target space may further include controlling the running duration of the fresh air device and the purification device.

[0068] Step 600, continuously obtain the usage status data in the target space.

[0069] Specifically, the usage status data is data related to human activities in the target space, which can be used to characterize the air circulation in the target space, or to characterize whether the oxygen in the target space is sufficient, or whether the content of exhaled carbon dioxide exceeds the standard. It can be understood that the usage status data in the target space can be used to determine whether it is necessary to perform an external circulation process on the indoor air in the target space to introduce fresh outdoor air into the target space.

[0070] Exemplarily, the usage status data may include the volume data of the target space, which can characterize the intensity of human activities in the target space. Taking the target space as a private room in a KTV as an example, the volume data can characterize the volume of singing in the private room. When people sing, they need to increase the amplitude of breathing and expand the chest cavity. Especially when singing loudly, they need to inhale a large amount of oxygen to increase the oxygen content in the lungs and mobilize the activity of the lungs to a greater extent. Therefore, the volume data of the target space can be used as the usage status data to determine whether it is necessary to perform an external circulation process on the indoor air in the target space. The volume data can be collected by setting a volume sensor in the target space.

[0071] Exemplarily, the usage status data may also include the usage duration data, which can characterize the duration of human activities in the target space. Since the target space is mostly in a closed state and the air does not circulate, the usage duration data of the target space can be used as the usage status data to determine whether it is necessary to perform an external circulation process on the indoor air in the target space. The usage duration data can be obtained by timing the duration when the target space is enabled, or by timing the duration when the equipment in the target space is turned on.

[0072] Exemplarily, the usage status data may also include the carbon dioxide (CO2) content, which is used to determine whether it is necessary to perform an external circulation process on the indoor air in the target space.

[0073] Step 800, when the usage status data meets the re-ventilation condition, perform an external circulation process on the indoor air in the target space.

[0074] Specifically, when the usage status data meets the re-ventilation condition, it indicates that the indoor air in the target space is not fresh enough and it is necessary to perform an external circulation process on the indoor air in the target space.

[0075] Furthermore, for different usage status data to meet the re-ventilation condition, it can be that the volume data in the target space is greater than the preset volume threshold, or that the usage duration data of the target space reaches the preset duration threshold, or that the carbon dioxide content in the target space reaches the preset upper limit of carbon dioxide content.

[0076] It can be understood that if it is determined that the re-ventilation condition is met and the indoor air in the target space is being subjected to an internal circulation process, it is necessary to control the switch from the internal circulation process to the external circulation process. In this case, it is necessary to control the fresh air device and the purification device to operate synchronously. If it is determined that the re-ventilation condition is met and there is no air circulation process in the target space, the external circulation process can be directly controlled. In this case, only the fresh air device needs to be controlled to operate.

[0077] The above air purification device, after detecting that the target space is enabled, obtains the indoor environmental data corresponding to the target space, and determines whether the ventilation condition is met according to the indoor environmental data, so as to perform an internal circulation process or an external circulation process on the indoor air in the target space; then continuously obtains the usage status data in the target space, and when the usage status data meets the re-ventilation condition, performs an external circulation process on the indoor air in the target space, so as to improve the air quality in the enclosed space of various leisure and entertainment places and ensure the health of users.

[0078] For the case where the indoor environmental data includes the number of indoor people, in an exemplary embodiment, as Figure 3 shown, step 400 includes the following steps 420 to 440, where:

[0079] Step 420, when the number of indoor people does not exceed the preset number threshold, it is determined that the ventilation condition is not met, and an internal circulation process is performed on the indoor air in the target space;

[0080] Step 440, when the number of indoor people exceeds the preset number threshold, it is determined that the ventilation condition is met, and an external circulation process is performed on the indoor air in the target space.

[0081] Among them, the preset number threshold is the number of people in activities that may cause a rapid decline in the air quality in the target space, and its specific value is not fixed, and can be determined according to the area size of the target space and the air purification efficiency. For example, in this embodiment, the preset number threshold can be set to 8 people.

[0082] Specifically, when the number of indoor people does not exceed the preset number threshold, it indicates that the air quality in the target space will not rapidly decline due to human activities. In response to this situation, it can be determined that the ventilation condition is not met, and only an internal circulation process needs to be performed on the indoor air in the target space to ensure good air quality in the target space.

[0083] Further, when the number of indoor people exceeds the preset number threshold, it indicates that the number of indoor people in the target space has exceeded a certain amount. As people move around, the air quality is very likely to drop rapidly. In response to this situation, it can be determined that the ventilation condition is met, and the indoor air in the target space is subjected to an external circulation process to supply fresh outdoor air to the target space, ensuring that the air quality will not drop rapidly and maintaining good air quality in the target space.

[0084] In this embodiment, by selecting the number of indoor people as the indoor environment data and considering the air quality situation that the target space is about to change to, it is possible to pre-judge whether it is necessary to perform an external circulation process on the target space to supply fresh outdoor air, effectively avoiding the situation where the air quality in the target space drops rapidly and cannot be improved in a short time, and ensuring the stability of the air quality in the target space.

[0085] In an exemplary embodiment, performing an internal circulation process on the indoor air in the target space in step 420 includes: performing an internal circulation process on the indoor air in the target space for a first preset duration.

[0086] Specifically, when it is determined that the ventilation condition is not met according to the indoor environment data, an internal circulation process on the indoor air in the target space can be started. Correspondingly, in order to save energy consumption, the duration of the internal circulation process can be controlled. For example, in this embodiment, after performing an internal circulation process on the indoor air in the target space for a first preset duration, the internal circulation process can be controlled to stop.

[0087] Among them, the first preset duration is the duration that can achieve the effect of improving the air quality situation in the target space, and the specific value can be determined according to the area size of the target space and the air purification efficiency. For example, in this embodiment, the first preset duration can be set to 10 min to 20 min.

[0088] In an exemplary embodiment, performing an external circulation process on the indoor air in the target space in step 440 includes: after performing an external circulation process on the indoor air in the target space for a second preset duration, converting to performing an internal circulation process for a third preset duration.

[0089] Specifically, when it is determined that the ventilation condition is met according to the indoor environment data, an external circulation process on the indoor air in the target space can be started. Similarly, in order to save energy consumption, the duration of the external circulation process can be controlled, that is, as shown in this embodiment, performing an external circulation process on the indoor air in the target space for a second preset duration.

[0090] Furthermore, since outdoor fresh air is introduced into the target space during the execution of the outer loop process, and the outdoor fresh air cannot ensure that all air quality indicators meet the standards. Therefore, in order to ensure the physical health of users in the target space, after the execution of the outer loop process, it is necessary to switch to the execution of the inner loop process to purify the outdoor air. To save energy consumption, the duration of the inner loop process executed at this time can be controlled, that is, as shown in this embodiment, the inner loop process of the indoor air in the target space is executed for a third preset duration.

[0091] Among them, the second preset duration can be the duration for fully exchanging outdoor air in the target space, and the specific value is not fixed, and can be determined according to the area size of the target space and the air purification efficiency.

[0092] Exemplarily, for the case where the indoor environmental data includes the number of indoor people, the second preset duration can be in a proportional relationship with the number of indoor people. It can be understood that the more indoor people there are in the target space, the faster the air quality deteriorates as people move. Therefore, the duration of the outer loop process needs to be set in a proportional relationship with the number of indoor people to avoid the situation where the air quality in the target space drops rapidly and cannot be improved in a short time. For example, in this embodiment, taking the preset number threshold of 8 people as an example, when the detected number of indoor people is 10, the second preset duration can be set to 10 min, and when the detected number of indoor people is 12, the second preset duration can be set to 20 min.

[0093] In addition, the third preset duration is the duration that can achieve the effect of improving the air quality in the target space, and the specific value can be determined according to the area size of the target space and the air purification efficiency, and can be the same as or different from the first preset duration. For example, in this embodiment, the third preset duration can be set to 10 min to 20 min.

[0094] For the case where the usage status data includes volume data, in an exemplary embodiment, as Figure 4 shown, step 800 includes step 820: when the volume data is greater than the preset volume threshold, it is determined that the re-ventilation condition is met, and after the inner loop process of the indoor air in the target space is executed for a fourth preset duration, it is switched to execute the inner loop process for a fifth preset duration.

[0095] Specifically, the preset volume threshold characterizes the volume value with a relatively high intensity of personnel activities in the target space. Taking the target space as the box space set in a KTV and the volume data as the volume of singing in the box as an example, the preset volume threshold can be set to 85 dB. In this case, it indicates that there is a user singing loudly, who needs to inhale a large amount of oxygen, increasing the amount of oxygen in the lungs and mobilizing the activity of the lungs to a large extent. Further, when the volume data is greater than the preset volume threshold, it is necessary to determine that the re-ventilation condition is met, and perform an external circulation process on the indoor air in the target space.

[0096] Further, in order to save energy consumption, the duration of the external circulation process can be controlled, that is, as shown in this embodiment, the external circulation process is performed on the indoor air in the target space for a fourth preset duration. Similarly, in order to purify the outdoor air introduced by the external circulation process, after the external circulation process is performed, it can be converted to perform an internal circulation process for a fifth preset duration.

[0097] Among them, consistent with the above description, the fourth preset duration and the fifth preset duration can be set according to the actual situation. The fourth preset duration can be set to be the same as the second preset duration, or can be different. For example, in this embodiment, the fourth preset duration can be set to 10 min. The fifth preset duration can be set to be the same as the third preset duration, or can be different. For example, it can be set to 10 min to 20 min.

[0098] For the case where the usage status data includes usage duration data, in an exemplary embodiment, continue to refer to Figure 4 As shown, step 800 includes step 840: when the usage duration data reaches the preset duration threshold, determine that the re-ventilation condition is met, and perform an external circulation process on the indoor air in the target space until it is detected that the target space is deactivated.

[0099] Specifically, the preset duration threshold characterizes that the personnel activity time in the target space is relatively long, and can be determined according to the area size of the target space and the number of indoor personnel. For example, it can be set to 0.5 h to 1 h.

[0100] Since the target space is mostly in a closed state and the air does not circulate, when the usage duration data reaches the preset duration threshold, it indicates that the indoor air in the target space is very likely to be thin, and users are prone to discomfort such as dizziness and chest tightness in the target space. Further, when the usage duration data reaches the preset duration threshold, it is necessary to determine that the re-ventilation condition is met, and perform an external circulation process on the indoor air in the target space.

[0101] Further, for the case where the usage duration data reaches the preset duration threshold, in order to ensure the continuous stability of the air quality in the target space, the external circulation process can be continuously performed until it is detected that the target space is deactivated.

[0102] Exemplarily, detecting whether the target space is deactivated can be similar to detecting whether the target space is activated. For example, it can be achieved by detecting whether there is no human activity in the target space, or by detecting whether the devices in the target space have stopped running, or by detecting whether the volume data in the target space is lower than a low volume threshold, where the low volume threshold represents the volume threshold for the presence of human activity.

[0103] Exemplarily, after detecting that the target space is deactivated, it can be to keep executing the outer loop process for a sixth preset duration and then stop executing the outer loop process and stop the operation of the air purification system. With such a design, it can ensure that when the target space is enabled later, the air quality of the indoor air will not be too poor.

[0121] The external loop processing module is further configured to determine that the re-ventilation condition is met when the usage duration data reaches the preset duration threshold, perform an external loop process on the indoor air in the target space until it is detected that the target space is deactivated.

[0123] In an exemplary embodiment, the outer loop processing module is further configured to control the fresh air device in the target space to start running.

[0124] In an exemplary embodiment, the outer loop processing module is further configured to control the fresh air device and the purification device in the target space to start running.

[0125] Each module in the above air purification device can be implemented in whole or in part by software, hardware, and their combination. The above modules can be embedded in the processor of the computer device in hardware form or independent of it, or stored in the memory of the computer device in software form, so that the processor can call and execute the operations corresponding to the above modules.

[0126] In an exemplary embodiment, as Figure 1 shown, an air purification system is provided, including a controller 110, and a fresh air device 120, a purification device 130, and a data acquisition component 140 connected to the controller 110. The data acquisition component 140 is used to acquire indoor environment data and usage status data. The controller 110 is used to control the fresh air device 120 and the purification device 130 to run according to the air purification method provided in the embodiments of the present application, and perform cyclic purification processing on the indoor air in the target space.

[0127] The solution provided by the air purification system to solve the problem is similar to the solution described in the above air purification method. Therefore, the specific limitations in the embodiments of the air purification system provided can refer to the limitations on the air purification method in the above text, and will not be repeated here.

[0128] In a specific embodiment, referring to Figure 6 shown, taking the target space as a box space set in a KTV as an example, an air purification method applied to the air purification system is provided.

[0129] Specifically, the air purification system includes a controller, and a fresh air device, a purification device, and a data acquisition component connected to the controller. The data acquisition component includes a people counter, a volume sensor, and a singing duration collector. Among them, the people counter is set at the door position of the target space, the volume sensor is set at any position in the target space, and the usage duration collector is set on the microphone of the target space.

[0130] Further, the air purification method applied to the above air purification system includes the following content:

[0131] After the personnel enter the target box, the people counter acquires the number of indoor personnel.

[0132] If the number of indoor personnel does not exceed the preset number threshold, control the purification device to start running and perform the inner circulation process for the first preset duration. If the number of indoor personnel exceeds the preset number threshold, control the fresh air device to start running and perform the outer circulation process for the second preset duration, and the duration of the second preset duration is proportional to the number of indoor personnel. Subsequently, control the fresh air device to stop running and the purification device to start running, and switch to perform the inner circulation process for the third preset duration.

[0133] After a user turns on the microphone and starts singing, judge the volume data in the target box. When people sing, they need to increase the amplitude of breathing and expand the chest cavity. Especially when singing loudly, they need to inhale a large amount of oxygen, increase the amount of oxygen in the lungs, and mobilize the activity of the lungs to a greater extent. When the volume data in the target box is greater than 85 dB (preset volume threshold), control the fresh air device to start running and perform the outer circulation process for the fourth preset duration (10 minutes). Subsequently, control the fresh air device to stop running and the purification device to start running, and switch to perform the inner circulation process for the fifth preset duration.

[0134] When it is detected that the microphone usage duration exceeds 0.5 h (preset duration threshold), control the fresh air device to start running and perform the outer circulation process until the users in the target box leave. Then, control the fresh air device to continue running for 10 minutes and then turn it off.

[0135] In this embodiment, through the above air purification system and air purification method, the problems of overcrowding and poor air circulation in the KTV box, and the decline in air quality after people sing and breathe are solved. Different modes are operated according to the number of people in the box, the singing volume, and the singing duration of people, so as to improve the air quality in the box and optimize the user experience.
