Description

Technical Field

[0001] This application relates to the field of air purification technology, and in particular to an air purification method, apparatus, equipment and storage medium. Background Technology

[0002] Currently, filter-based air purifiers remain the mainstream in the market, and their functions are becoming increasingly diversified, with more and more purifiers offering humidification and dehumidification functions. However, most of these multi-functional purifiers are simply a combination of different functions; when using one function, it can only be used as a single appliance. For example, a humidifying air purifier only functions as a humidifier, without any interoperability between the functions. This leads to a waste of resources, and consumers end up with a multi-functional product rather than a truly multi-functional air purifier. Furthermore, the gaseous pollutants in the home environment are numerous and complex. For filter-based air purifiers, these complex gaseous pollutants cause the filters to reach their lifespan more quickly, undoubtedly accelerating the frequency of filter replacement. Moreover, the presence of organic acids and other substances in the air is a major reason why filters often develop a sour odor during use. Summary of the Invention

[0057] This application provides an air purification method. Figure 1 This is a schematic diagram illustrating the implementation process of an air purification method provided in an embodiment of this application, as shown below. Figure 1 As shown, it includes:

[0058] Step S1: Upon obtaining the trigger information for activating the air purifier's gaseous pollutant removal mode, the first ambient humidity in the room is obtained.

[0059] In this embodiment, the electronic device can detect the concentration of gaseous pollutants in the room using a gas sensor; if the concentration of gaseous pollutants exceeds a second concentration threshold, trigger information is generated to activate the air purifier's gaseous pollutant removal mode. In this embodiment, the second concentration threshold can be configured. A concentration value exceeding the second concentration threshold indicates a high level of gaseous pollutants and poor air quality.

[0060] In some embodiments, trigger information for the user to activate the air purifier's gaseous pollutant removal mode can be obtained. The electronic device can be equipped with a button to activate the air purifier's gaseous pollutant removal mode. The user can click the button, thereby enabling the electronic device to obtain the trigger information for the user to activate the air purifier's gaseous pollutant removal mode.

[0061] In some embodiments, users can trigger the air purifier's gaseous pollutant removal mode by inputting voice information. In some embodiments, the air purifier is equipped with a display module, and an electronic device is communicatively connected to the display module. The electronic device detects the concentration of gaseous pollutants in the room using a gas sensor and then displays the results on the display module to prompt the user whether to activate the air purifier's gaseous pollutant removal mode.

[0062] In some embodiments, the electronic device can detect the concentration values ​​of dust pollutants and gaseous pollutants in the room through a gas sensor and a dust sensor; when the concentration value of dust pollutants is greater than the dust pollutant concentration threshold and the concentration value of gaseous pollutants is greater than the gaseous pollutant concentration threshold, trigger information for starting the dust removal mode of the air purifier is generated; when it is determined that the dust removal mode has been completed, trigger information for starting the gaseous pollutant removal mode of the air purifier is generated.

[0063] In some embodiments, upon receiving trigger information to activate the air purifier's gaseous pollutant removal mode, the electronic device can control the gaseous sensor and humidity sensor to turn on, so as to detect the indoor humidity and gaseous pollutant concentration in real time.

[0064] Step S2: When the first ambient humidity is less than the first humidity threshold, turn on the humidification function of the air purifier.

[0065] In this embodiment, the electronic device can send control commands to the humidification module of the air purifier to control the humidification module to turn on. After the humidification module is turned on, the air purifier humidifies the room.

[0066] In this embodiment of the application, the first humidity threshold can be configured. For example, the first humidity threshold can be configured to 70%.

[0067] In this embodiment of the application, when the first ambient humidity is less than the first humidity threshold, indicating that the humidity is not high, the air purifier is controlled to turn on the humidification function in order to better adsorb gaseous pollutants in the air.

[0068] Step S3: If the indoor ambient humidity is greater than the first humidity threshold after the humidification function is turned on, the humidification function is turned off, and a first waiting time is determined based on the current concentration of gaseous pollutants in the room.

[0069] In this embodiment of the application, the electronic device can detect the indoor humidity after the humidification function is turned on, and then compare whether the indoor humidity after the humidification function is turned on is greater than a first humidity threshold.

[0070] In this embodiment of the application, if the indoor humidity after the humidification function is turned on is less than the first humidity threshold, humidification continues; if the indoor ambient humidity after the humidification function is turned on is greater than the first humidity threshold, the humidification function is turned off.

[0071] In this embodiment, the electronic device can detect the concentration of gaseous pollutants in the room in real time using a gas sensor. After determining the concentration of gaseous pollutants, the electronic device can determine a first waiting time. In this embodiment, the higher the concentration of gaseous pollutants, the longer the first waiting time.

[0072] In this embodiment of the application, the body pollutants may include: formaldehyde, ammonia, organic acids, etc.

[0073] In this embodiment of the application, by making the indoor humidity greater than a first humidity threshold, pollutants in the air can be better adsorbed, which is beneficial for capturing pollutants in the air that are easily soluble in water.

[0074] Step S4: After the first waiting time has been reached, the dehumidification function of the air purifier is turned on.

[0075] In this embodiment of the application, the electronic device starts timing after determining the first waiting time. When the first waiting time is reached, a control command can be sent to the dehumidification module of the air purifier to activate the dehumidification function.

[0076] In this embodiment of the application, after the dehumidification function is turned on, the air purifier dehumidifies the room.

[0077] Step S5: If the indoor ambient humidity is less than the second humidity threshold after the dehumidification function is turned on, the dehumidification function is turned off, and the air purifier's purification function is turned on as the first purification function. The first humidity threshold is greater than the second humidity threshold. When the first purification function is turned on, the air purifier's fan runs at its highest speed.

[0078] In this embodiment, during dehumidification, the electronic device detects the indoor humidity in real time using a humidity sensor. The second humidity threshold can be configured; for example, the second humidity threshold can be 40%.

[0079] In this embodiment of the application, the air purifier does not perform initialization after the initialization function is turned off.

[0080] In this embodiment, when the gaseous pollutant removal mode is activated, the humidification function is first activated to increase the indoor air humidity, using water molecules to capture water-soluble gaseous pollutants in the air. Then, the dehumidification function collects and processes the water in the air. Finally, the purification function removes the remaining gaseous pollutants in the air, thereby achieving rapid removal of pollutants from the air.

[0081] This application provides an air purification method that, upon receiving trigger information to activate the gaseous pollutant removal mode of an air purifier, controls the humidification, dehumidification, and air purification functions in conjunction based on the ambient humidity and the status of gaseous pollutants. This method can better purify the air, improve the user experience, and maximize the utilization of the various functions of a multi-functional humidifier.

[0082] In some embodiments, after step S1, the method further includes:

[0083] Step S6: When the first ambient humidity is greater than the first humidity threshold, the dehumidification function is activated.

[0084] In this embodiment of the application, after the dehumidification function is turned on, the air purifier dehumidifies the room.

[0085] Step S7: If the indoor ambient humidity is less than the third humidity threshold after the dehumidification function is turned on, the dehumidification function is turned off and the humidification function is turned on.

[0086] In this embodiment of the application, the third humidity threshold can be configured. For example, the third humidity threshold can be configured to 50%.

[0087] Step S8: If the indoor ambient humidity is greater than the first humidity threshold after the humidification function is turned on, the humidification function is turned off, and a second waiting time is determined based on the current concentration of gaseous pollutants in the room.

[0088] Step S9: After the second waiting time has been reached, the dehumidification function is turned on again.

[0089] Step S10: If the indoor ambient humidity is less than the second humidity threshold after the dehumidification function is turned on, the dehumidification function is turned off, and the air purifier's purification function is turned on as the first purification function, wherein the first humidity threshold is greater than the third humidity threshold, and the third humidity threshold is greater than the second humidity threshold.

[0090] In some embodiments, after step S5 or step S10, the method further includes:

[0091] Step S11: After the first purification function has been activated for a preset time, the first purification function is switched to the second purification function. When the second purification function is activated, the air purifier adjusts the fan speed based on the concentration of pollutants, wherein the concentration of pollutants is directly proportional to the fan speed.

[0092] In this embodiment of the application, the second purification function can be considered as an automatic purification function.

[0093] In some embodiments, the method further includes:

[0094] Step S12: Upon receiving the trigger information for activating the dust removal mode of the air purifier, obtain the second ambient humidity in the room.

[0095] In this embodiment, the electronic device can detect the concentration of dust pollutants in the room using a dust sensor; if the concentration of dust pollutants exceeds a second concentration threshold, it generates trigger information to activate the dust removal mode of the air purifier; or, it acquires trigger information indicating that the user wants to activate the dust removal mode of the air purifier. In this embodiment, the electronic device can be equipped with a button to activate the dust removal mode of the air purifier. The user can click the button, thereby enabling the electronic device to acquire the trigger information indicating that the user wants to activate the dust removal mode of the air purifier. In some embodiments, the user can trigger the activation of the dust removal mode of the air purifier by inputting voice information. In some embodiments, the air purifier is equipped with a display module, and the electronic device is communicatively connected to the display module. The electronic device detects the concentration of dust pollutants in the room using a gas sensor and then displays the information on the display module to prompt the user whether to activate the dust removal mode of the air purifier.

[0096] In some embodiments, the electronic device can detect the concentration values ​​of dust pollutants and gaseous pollutants in the room through a gas sensor and a dust sensor; when the concentration value of dust pollutants is greater than a dust pollutant concentration threshold and the concentration value of gaseous pollutants is greater than a gaseous pollutant concentration threshold, trigger information is generated to start the dust removal mode of the air purifier.

[0097] Step S13: When the second ambient humidity is less than the fourth humidity threshold, the humidification function is turned on.

[0098] In this embodiment of the application, the fourth humidity threshold can be configured; for example, the fourth humidity threshold can be 60%.

[0099] Step S14: If the indoor ambient humidity is higher than the fourth humidity threshold after the humidification function is turned on, the humidification function is turned off, and the air purifier's purification function is turned on as the second purification function. When the second purification function is turned on, the air purifier adjusts the fan speed based on the concentration value of pollutants, and the concentration value of pollutants is proportional to the fan speed.

[0100] Step S15: If the current concentration of dust in the room is lower than the first concentration threshold after the purification function is turned on as the second purification function, the dehumidification function is turned on.

[0101] In this embodiment of the application, the first concentration threshold can be configured.

[0102] Step S16: If the indoor ambient humidity is less than the second humidity threshold after the dehumidification function is turned on, the dehumidification function is turned off, and the air purifier is controlled to continue operating in the second purification mode, wherein the fourth humidity threshold is less than the first humidity threshold and the fourth humidity threshold is greater than the second humidity threshold.

[0103] In some embodiments, after S12, the method further includes:

[0104] Step S17: When the second ambient humidity is greater than the fourth humidity threshold, the air purifier's purification function is turned on as the first purification function.

[0105] Step S18: If the current concentration of dust in the room is lower than the first concentration threshold after the purification function is turned on as the first purification function, the dehumidification function is turned on.

[0106] Step S19: If the indoor ambient humidity is less than the second humidity threshold after the dehumidification function is turned on, the dehumidification function is turned off, and the purification function of the air purifier is controlled to the second purification function.

[0107] The air purification method provided in this application first increases the air humidity to a certain value through the humidification function, thereby improving the dust removal effect after the purifier's purification function is turned on. After the dust is purified, the indoor air humidity is adjusted to a comfortable range for the human body through the dehumidification function, thereby achieving rapid removal of indoor air dust.

[0108] The air purification method provided in this application integrates the humidification and dehumidification functions of a multi-functional air purifier, maximizing the utilization of all purifier functions. This facilitates product promotion, increases product selling points, and attracts consumers. Simultaneously, humidification and dehumidification effectively remove some water-soluble gaseous pollutants from the air, extending the filter's lifespan and reducing replacement frequency, thus minimizing pollution from discarded filters. Furthermore, prioritizing the removal of organic acids and other substances from the air through humidification and dehumidification reduces the likelihood of filters developing a sour odor.

[0109] Based on the foregoing embodiments, this application further provides an air purification method, wherein the air purifier is equipped with humidification, dehumidification and purification functions.

[0110] In this embodiment, when the gas sensor detects a high concentration of gaseous pollutants indoors, it automatically switches to the rapid gaseous pollutant removal mode; or when the user observes a high concentration of gaseous pollutants through the purifier's display, they can manually switch to the rapid gaseous pollutant removal mode.

[0111] In some embodiments, when the dust sensor detects a high concentration of indoor dust pollutants, it automatically switches to the rapid dust removal mode; or when the user observes a high concentration of gaseous pollutants on the purifier's display, they can manually switch to the rapid gaseous pollutant removal mode.

[0112] In some embodiments, when the sensor detects that both gaseous pollutants and particulate pollutants are at high levels, the system first switches to a rapid dust removal mode to complete one cycle, and then switches to a rapid gaseous pollutant removal mode.

[0113] For example, the mode for removing gaseous pollutants is as follows:

[0114] When the purifier starts its rapid gaseous pollutant removal mode, the humidity sensor detects that the indoor humidity is below 70%, and the humidification mode is activated. The humidity sensor continues to monitor the humidity until it reaches above 70%. After humidification is turned off, a waiting period is initiated (the waiting time depends on the concentration of gaseous pollutants detected by the sensor; the higher the concentration, the longer the waiting time). Then, the dehumidification mode is activated again, and the humidity sensor monitors the humidity until it drops below 40%. The dehumidification function is then deactivated, and the purifier activates its highest purification mode for continuous purification. After a period of time, the purifier switches to automatic mode (automatically adjusting the fan speed based on the pollutant concentration detected by the sensor).

[0115] When the air purifier starts its rapid gaseous pollutant removal mode, the humidity sensor detects that the indoor humidity is above 70%, and immediately activates the dehumidification mode. The humidity sensor continues to monitor the humidity until it drops below 50%. At this point, the dehumidification mode is turned off while the humidification mode is activated. The humidity sensor continues to monitor the humidity until it reaches above 70%. After turning off the humidification mode, wait for a period of time (the time depends on the concentration of gaseous pollutants detected by the sensor; the higher the concentration, the longer the waiting time). Then, activate the dehumidification mode again, and the humidity sensor continues to monitor the humidity until it drops below 40%. The dehumidification function is then turned off, and the air purifier activates its highest purification mode for continuous purification. After a period of time, the air purifier switches to automatic mode (automatically adjusting the fan speed based on the pollutant concentration detected by the sensor).

[0116] The dust removal modes are as follows:

[0117] When the purifier starts its rapid dust removal mode, the humidity sensor detects that the indoor humidity is below 60%, and the humidification function is activated. The humidity sensor continues to monitor the humidity until it drops above 60%, at which point humidification stops. Simultaneously, the purification function is activated, and the fan starts to purify the air until the dust sensor detects that the dust concentration is below a certain value. The dehumidification function is then activated until the humidity drops below 40%, at which point the dehumidification function is turned off. The purifier then operates in automatic mode (the fan speed is automatically adjusted based on the pollutant concentration detected by the sensor).

[0118] When the air purifier is turned on, the sensor detects a high concentration of dust in the air, and the humidity sensor detects that the indoor humidity is higher than 60%. The purification function is activated and the fan starts. The purification mode continues to purify at the highest level until the dust sensor detects a low dust concentration. Then, the dehumidification function is activated until the humidity reaches 40%. The dehumidification function then stops, and the purifier operates in automatic mode.

[0119] The air purification method provided in this application maximizes the use of the various functional resources of a multi-functional purifier to accelerate the rapid removal of pollutants such as dust, formaldehyde, ammonia, and organic acids from indoor air.

[0120] Based on the foregoing embodiments, this application provides an air purification device. The various modules and units included in the device can be implemented by a processor in a computer device; of course, they can also be implemented by specific logic circuits. In the implementation process, the processor can be a central processing unit (CPU), a microprocessor unit (MPU), a digital signal processor (DSP), or a field programmable gate array (FPGA), etc.

[0126] The third activation module is used to turn off the dehumidification function and activate the air purifier's purification function as the first purification function when the indoor ambient humidity is less than the second humidity threshold after the dehumidification function is activated. The first humidity threshold is greater than the second humidity threshold. When the first purification function is activated, the air purifier's fan runs at its highest speed.
