Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to an air purification method, an air purification device, and a readable storage medium. Background Technology

[0002] Currently, there are generally two common air purification methods: one uses ultraviolet lamps to release ultraviolet light for sterilization and air purification; the other uses photocatalytic oxidation technology, which combines ultraviolet lamps with photocatalysts. Turning on the ultraviolet lamp triggers the photocatalyst to produce bactericidal agents, thus purifying the air. However, ultraviolet lamp purification can only purify air within its irradiation range; while photocatalytic oxidation technology is not effective and fast in purifying indoor environments and wastes energy. Furthermore, if excessive amounts of reactive oxygen species (ROS) are generated, it can negatively impact indoor air health. Therefore, existing air purification methods have relatively poor air purification effects. Summary of the Invention

[0020] Obtain the current magnetic field strength of the magnetic field module;

[0021] When the current magnetic field strength is not within the magnetic field strength range, the operating parameters are adjusted to bring the magnetic field strength of the magnetic field module into the magnetic field strength range.

[0022] In one embodiment, after the step of activating the purification module and controlling the magnetic field module to operate according to the operating parameters to adjust the magnetic field strength generated by the magnetic field module, the method further includes:

[0037] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0038] As one implementation scheme, refer to Figure 1 , Figure 1 This is a schematic diagram of the hardware architecture of the air purification device involved in the embodiments of the present invention, as shown below. Figure 1 As shown, the air purification device may include a processor 101, such as a CPU, a memory 102, a communication bus 103, a purification module 104, and a magnetic field module 105, wherein the communication bus 103 is used to realize the connection and communication between these modules.

[0039] Memory 102 can be high-speed RAM or stable memory (non-volatile memory), such as disk storage. Figure 1 As shown, the memory 102, which is a computer-readable storage medium, may include an air purification program; and the processor 101 may be used to invoke the air purification program stored in the memory 102 and perform the following operations:

[0040] To obtain the concentration of pollutants in the air;

[0041] The operating parameters of the magnetic field module are determined based on the concentration of the pollutants.

[0042] The purification module is turned on and the magnetic field module is controlled to operate according to the operating parameters to adjust the magnetic field strength generated by the magnetic field module.

[0043] In one embodiment, the processor 101 can be used to invoke an air purification program stored in the memory 102 and perform the following operations:

[0044] The target magnetic field strength of the magnetic field module is determined based on the pollutant concentration.

[0045] The operating parameters of the magnetic field module are determined based on the magnetic field strength range in which the target magnetic field strength is located.

[0046] In one embodiment, the processor 101 can be used to invoke an air purification program stored in the memory 102 and perform the following operations:

[0047] Obtain the concentration range of the pollutant;

[0048] The target magnetic field strength of the magnetic field module is determined based on the concentration range.

[0051] When the current magnetic field strength is not within the magnetic field strength range, the operating parameters are adjusted to bring the magnetic field strength of the magnetic field module into the magnetic field strength range.

[0052] In one embodiment, the processor 101 can be used to invoke an air purification program stored in the memory 102 and perform the following operations:

[0053] After the magnetic field module has run for the target purification time according to the operating parameters, the purification module and the magnetic field module are turned off.

[0054] In one embodiment, the processor 101 can be used to invoke an air purification program stored in the memory 102 and perform the following operations:

[0055] Obtain the current temperature and / or current humidity of the air;

[0056] The target purification duration is determined based on the current temperature and / or current humidity.

[0057] Reference Figure 2 , Figure 2 This is a schematic flowchart of the first embodiment of the air purification method of the present invention, the air purification method comprising:

[0058] Step S10: Obtain the concentration of pollutants in the air;

[0059] In this embodiment, existing air purification methods that use ultraviolet lamps to release ultraviolet light for sterilization can only purify the air within the irradiation range. Existing air purification technologies that use photocatalysis to combine ultraviolet lamps with photocatalysts, where the ultraviolet lamps trigger the photocatalysts to generate bactericidal factors, require a certain amount of time to take effect. They are not effective and quick in sterilizing and purifying the indoor environment and waste energy. Therefore, the air purification effect of existing methods is not ideal.

[0060] To address the aforementioned technical issues, this invention proposes an air purification method. Based on existing photohydrogen purification technology, an external magnetic field is added to enhance the generation of bactericidal factors in the purification module and improve sterilization efficiency through the magnetoelectric effect. Simultaneously, the magnetic field is used to remove particulate matter pollution from the air, thereby improving the purification effect of the air purification device.

[0061] Reference Figure 5 , Figure 5 This is a schematic diagram of the modular structure of the air purification device of the present invention. Figure 5As shown, the air purification device includes a control module 1, a drive module 2, a purification module 3, and a magnetic field module 4. The purification module 3 includes a photocatalyst 31 and a light-emitting element 32. The light emitted by the light-emitting element 32 irradiates the photocatalyst 31 to generate bactericidal factors. The photocatalyst 31 can be TiO2. In other embodiments, the photocatalyst 31 can also be other photocatalyst materials suitable for purification, such as ZrO2, ZnO, CdS, WO3, Fe2O3, PbS, SnO2, ZnS, SrTiO3, and SiO2. The light-emitting element 32 can be an ultraviolet lamp. If the light-emitting element 32 is an ultraviolet lamp, its wavelength can be 185nm or 254nm. In other embodiments, the light-emitting element 32 can be other elements that can trigger the photocatalyst 31 to generate bactericidal factors. The magnetic field module 4 can be a magnetic field generator, including a first magnetic field generator 41 and a second magnetic field generator 42 arranged opposite to each other. The purification module 3 is located within the magnetic field generated by the magnetic field module 4. It should be noted that the positional relationship between the magnetic field module 4 and the purification module 3 in the figure is only an optional setting and is not a limitation on the positional relationship between the magnetic field module 4 and the purification module 3. As long as the purification module 3 can be located within the magnetic field generated by the magnetic field module 4, the air purification method proposed in this invention can be implemented.

[0062] Specifically, after the air purifier enters the air purification mode, it drives the purification module 3. The light emitted by the light-emitting element 32 shines on the photocatalyst 31, triggering the photocatalyst to generate bactericidal factors to purify the air. At the same time, it drives the magnetic field module 4 to generate a magnetic field. The magnetic field generated by the magnetic field module 4 acts on the purification module 3 (mainly on the photocatalyst 31 of the purification module 3). Utilizing the negative magnetoelectric effect of the magnetic field, the rate at which the purification module 3 generates bactericidal factors can be enhanced. In addition, when particulate matter in the air passes through the magnetic field, it will be deflected by the Lorentz force, causing the particulate matter to agglomerate and settle, thereby removing particulate pollution from the air. The air purification method proposed in this invention greatly improves the air purification effect of the air purifier.

[0063] In this embodiment, the executing entity is an air purification device. An air purification device is a device that can adsorb, decompose, or transform various air pollutants to purify the air. For example, an air purification device can be an air cleaner, an air freshener, an air purifier, or an air conditioner. Of course, in other embodiments, the air purification device can also be other devices used to clean the air, and this embodiment does not limit it.

[0064] In this embodiment, the air purification device can obtain the concentration of pollutants contained in the air. Pollutants refer to substances that pollute the air. Pollutants can be one of microorganisms (such as bacteria), formaldehyde, or particulate matter. Of course, pollutants can also be multiple of microorganisms, formaldehyde, and particulate matter. Pollutant concentration refers to the content of pollutants in the air. If the pollutant is one of microorganisms, formaldehyde, or particulate matter, the pollutant concentration is the content of that type of pollutant in the air. If the pollutants are multiple of microorganisms, formaldehyde, or particulate matter, by obtaining the concentration of each pollutant in the air separately, the concentration of the pollutant with the highest concentration can be determined as the pollutant concentration. Alternatively, the average concentration of various pollutants can be determined as the pollutant concentration. Furthermore, a certain weight can be assigned to the concentration of each pollutant, and the pollutant concentration can be determined based on the weight of the concentration of each pollutant.

[0065] In this embodiment, the air purification device is equipped with a pollutant concentration detection module. Figure 5 (Not specified) A pollutant concentration detection module refers to a device in an air purification system used to detect pollutants and calculate their concentration. For example, a pollutant concentration detection module can be a pollutant detector, including but not limited to a microbial detector, a formaldehyde detector, and a particulate matter detector.

[0066] Specifically, the air purifier is turned on and enters the air purification mode. The pollutant detection module detects pollutants in the air and calculates the concentration of pollutants to obtain the concentration of pollutants in the air.

[0067] Step S20: Determine the operating parameters of the magnetic field module based on the pollutant concentration;

[0068] In this embodiment, after the air purifier obtains the pollutant concentration, it determines the operating parameters of the magnetic field module 4 in the air purifier based on the pollutant concentration. The magnetic field module 4 refers to the device in the air purifier used to generate a magnetic field. For example, the magnetic field module 4 can be a magnetic field generator. The strength of the magnetic field generated by the magnetic field generator can be controlled by controlling the operating parameters of the magnetic field generator. The operating parameters of the magnetic field module 4 include at least one of the following: the driving voltage of the magnetic field module 4 (including the driving voltage of the first magnetic field generator 41 and the second magnetic field generator 42); the power of the magnetic field module 4 (including the power of the first magnetic field generator 41 and the second magnetic field generator 42); the distance between the first magnetic field generator 41 and the second magnetic field generator 42, which are positioned opposite each other in the magnetic field module 4; and the number of coils connected to the first magnetic field generator 41 and the second magnetic field generator 42, which are positioned opposite each other in the magnetic field module 4.

[0069] Specifically, after the air purification device obtains the pollutant concentration, it can determine at least one of the following operating parameters based on the pollutant concentration: the driving voltage of the magnetic field module 4, the power of the magnetic field module 4, the distance between the first magnetic field generator 41 and the second magnetic field generator 42 that are arranged opposite to each other in the magnetic field module 4, and the number of coils connected to the first magnetic field generator 41 and the second magnetic field generator 42 that are arranged opposite to each other in the magnetic field module 4.

[0070] Step S30: Turn on the purification module and control the magnetic field module to operate according to the operating parameters to adjust the magnetic field strength generated by the magnetic field module.

[0071] In this embodiment, after determining the operating parameters of the magnetic field module 4, the air purification device activates the purification module 3. Light emitted from the light-emitting element 32 of the purification module 3 illuminates the photocatalyst 31, triggering the photocatalyst to generate bactericidal factors to purify the air. Simultaneously, the operation of the magnetic field module 4 is controlled according to the determined operating parameters to regulate the magnetic field strength generated by the module. The magnetic field generated by the module 4 acts on the purification module 3. Utilizing the negative magnetoelectric effect of the magnetic field, the rate at which the purification module 3 generates bactericidal factors can be enhanced. Furthermore, when airborne particles pass through the magnetic field, they are deflected by the Lorentz force, causing them to agglomerate and settle, thus removing particulate pollution from the air. The air purification method proposed in this invention significantly improves the air purification effect of the air purification device.

[0072] In the technical solution provided in this embodiment, the air purification device detects the concentration of pollutants in the air, determines the operating parameters of the magnetic field module 4 in the air purification device based on the detected pollutant concentration, and then drives the purification module 3 to operate. At the same time, the magnetic field module 4 is driven to operate according to the determined operating parameters of the magnetic field module 4 to adjust the magnetic field strength generated by the magnetic field module 4. This solution applies a magnetic field to the purification module 3 through the magnetic field module 4, which accelerates the purification efficiency of the purification module 3 and can remove particulate matter in the air, thereby improving the purification effect of the air purification device.

[0073] Reference Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the air purification method of the present invention. Based on the first embodiment, the steps of S20 above include:

[0074] Step S21: Determine the target magnetic field strength of the magnetic field module based on the pollutant concentration;

[0075] In this embodiment, after the air purification device obtains the pollutant concentration, it can obtain the target magnetic field strength of the magnetic field module 4 based on the pollutant concentration. The target magnetic field strength refers to the magnetic field strength that needs to be added to achieve a better air purification effect based on the pollutant concentration in the air.

[0076] Specifically, after the air purification device obtains the pollutant concentration, it determines the concentration range within which the pollutant concentration falls, and then determines the target magnetic field strength of the magnetic field module 4 based on the determined concentration range. The concentration range refers to the range of pollutant concentration, and multiple concentration ranges can be set. For example, four concentration ranges can be set: (10000, +∞), (5000, 10000), (2500, 5000), and (0, 2500). The unit of pollutant concentration is cfu / m³. 3 Different concentration ranges correspond to different target magnetic field intensities in magnetic field module 4. Generally, the larger the numerical value of the concentration range, the greater the target magnetic field intensity. The target magnetic field intensities H1 corresponding to the concentration range (10000, +∞), H2 corresponding to (5000, 10000), H3 corresponding to (2500, 5000), and H4 corresponding to (0, 2500) are in the following order: H1 > H2 > H3 > H4. It should be noted that the criteria for dividing the pollutant concentration ranges, the number of concentration ranges, and the target magnetic field intensity corresponding to each concentration range can be set according to actual needs. This embodiment does not limit these settings.

[0077] Specifically, after the air purification device obtains the pollutant concentration, it determines the concentration range in which the pollutant concentration is located, and then determines the target magnetic field strength of the magnetic field module 4 corresponding to the determined concentration range.

[0078] Step S22: Determine the operating parameters of the magnetic field module based on the magnetic field strength range in which the target magnetic field strength is located.

[0079] In this embodiment, after the air purifier obtains the target magnetic field strength of the magnetic field module 4, it determines the operating parameters of the magnetic field module 4 according to the magnetic field strength range in which the target magnetic field strength is located. The magnetic field strength range refers to the range of magnetic field strength, and multiple magnetic field strength ranges can be set. For example, (0, 20000), (2000, 40000), (4000, 6000), (6000, 8000), (8000, 10000), (10000, 12000), and (12000, +∞) can be set. The unit of magnetic field strength is OE. Different magnetic field strength ranges correspond to different operating parameters of the magnetic field module 4. For example, the driving voltage of magnetic field module 4 corresponding to the magnetic field strength range (0, 20000) is U1, the driving voltage of magnetic field module 4 corresponding to the magnetic field strength range (2000, 40000) is U2, the driving voltage of magnetic field module 4 corresponding to the magnetic field strength range (4000, 6000) is U3, the driving voltage of magnetic field module 4 corresponding to the magnetic field strength range (6000, 8000) is U4, the driving voltage of magnetic field module 4 corresponding to the magnetic field strength range (8000, 10000) is U5, the driving voltage of magnetic field module 4 corresponding to the magnetic field strength range (10000, 12000) is U6, and the driving voltage of magnetic field module 4 corresponding to the magnetic field strength range (12000, +∞) is U7. Generally speaking, the larger the value of the magnetic field strength range, the larger the value of its corresponding operating parameter, that is, U7>U6>U5>U4>U3>U2>U1. The same applies to other operating parameters, which will not be elaborated here. It should be noted that the criteria for dividing the magnetic field strength ranges, the number of magnetic field strength ranges, and the operating parameters corresponding to each magnetic field strength range can be set according to actual needs, and this embodiment does not limit them.

[0080] Specifically, after the air purifier obtains the target magnetic field strength of the magnetic field module 4, it determines the magnetic field strength range in which the target magnetic field strength is located, and then obtains the operating parameters of the magnetic field module 4 based on the magnetic field strength range.

[0081] Furthermore, after determining the operating parameters of the magnetic field module 4, the air purification device turns on the purification module 3 and controls the operation of the magnetic field module 4 according to the determined operating parameters.

[0082] Furthermore, the air purifier activates the purification module 3 and, based on the determined operating parameters of the magnetic field module 4, controls its operation. It then acquires the current magnetic field strength of the magnetic field module 4. If the current magnetic field strength is outside the specified range, the operating parameters of the magnetic field module 4 are adjusted to bring its magnetic field strength within that range. The current magnetic field strength refers to the magnetic field strength detected by the magnetic field module 4 at the current moment during operation. Specifically, the air purifier includes a magnetic field strength detection module (…). Figure 5 (Not explicitly marked), the magnetic field strength detection module refers to a device in the air purifier that can be used to detect the magnetic field strength. For example, the magnetic field strength detection module can be a magnetic field strength detector. Of course, in other embodiments, the magnetic field strength detection module can also be other devices that can be used to detect the magnetic field strength, and this embodiment does not limit this. The air purifier turns on the purification module 3 and simultaneously controls the operation of the magnetic field module 4 according to the determined operating parameters. The magnetic field strength detection module detects the current magnetic field strength of the magnetic field module 4 and determines whether the detected current magnetic field strength is within the magnetic field strength range of the target magnetic field strength. If the current magnetic field strength is not within the magnetic field strength range of the target magnetic field strength, the operating parameters of the magnetic field module 4 are adjusted to adjust the magnetic field strength generated by the magnetic field module 4 to the magnetic field strength range of the target magnetic field strength. By detecting and adjusting the current magnetic field strength of the magnetic field module 4, it can be ensured that the current magnetic field strength of the magnetic field module 4 is always within the magnetic field strength range of the target magnetic field strength, thereby ensuring the accuracy of the operating parameters of the magnetic field module 4 and guaranteeing the purification effect of the air purifier.

[0083] In the technical solution provided in this embodiment, the target magnetic field strength of the magnetic field module 4 is determined based on the pollutant concentration, and the operating parameters of the magnetic field module 4 are determined based on the magnetic field strength range in which the target magnetic field strength falls. This solution realizes the correspondence between pollutant concentration and the operating parameters of the magnetic field module 4, and can accurately determine the operating parameters of the magnetic field module 4 based on the pollutant concentration, thereby improving the air purification effect of the air purification device.

[0084] Reference Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the air purification method of the present invention. Based on the first embodiment, the method further includes the following step after step S30:

[0085] Step S40: Obtain the current temperature and / or current humidity of the air;

[0086] In this embodiment, the air purifier activates the purification module 3 and simultaneously controls the magnetic field module 4 to operate according to the determined operating parameters, detecting at least one of the current air temperature and current humidity. The air purifier can acquire the current air temperature, the current air humidity, or both simultaneously.

[0087] Specifically, the air purification device is equipped with a temperature detection module. Figure 5 (not marked) and humidity detection module ( Figure 5At least one of the following (not specified): where a temperature detection module refers to a device used to detect air temperature, such as an air temperature sensor; and a humidity detection module refers to a device used to detect air humidity, such as an air humidity sensor. An air purifier can detect the current air temperature through a temperature detection module, and it can also detect the current air humidity through a humidity detection module, or it can simultaneously detect both the current air temperature and humidity using both modules.

[0088] Step S50: Determine the target purification duration based on the current temperature and / or current humidity.

[0089] In this embodiment, after obtaining at least one of the current air temperature and current humidity, the air purifier determines the target purification duration based on at least one of the current air temperature and current humidity, wherein the target purification duration refers to the duration required for this air purification.

[0090] In this embodiment, after obtaining at least one of the current temperature and current humidity of the air, the air purifier obtains a preset purification time, and then corrects the preset purification time based on at least one of the current temperature and current humidity of the air to obtain the target purification time of the air purifier.

[0091] In one embodiment, the air purifier can adjust its preset purification time to obtain a target purification time based on the current air temperature. Specifically, if the current air temperature is lower than a first preset temperature, the preset purification time is increased by the first preset temperature to obtain the target purification time; if the current air temperature is higher than the first preset temperature but lower than a second preset temperature, the preset purification time is decreased by the second preset temperature to obtain the target purification time; if the current air temperature is greater than or equal to the second preset temperature, the preset purification time is decreased by a third preset temperature to obtain the target purification time; wherein the third purification time is greater than or equal to the second purification time. The first preset temperature can be 15℃-25℃; the second preset temperature can be 25℃-35℃; the first purification time can be 1%-100% of the preset purification time; the second purification time can be 1%-33.3% of the preset purification time; and the third purification time can be 33.3%-66.7% of the preset purification time. It should be noted that in other embodiments, the preset purification time, the first preset temperature, the second preset temperature, the first purification time, the second purification time, and the third purification time can be set according to the actual situation, and this embodiment does not limit this.

[0092] In one embodiment, the air purifier can adjust its preset purification time to obtain a target purification time based on the current humidity of the air. Specifically, if the current humidity of the air is less than a first preset humidity, the preset purification time is increased by a fourth purification time to obtain the target purification time; if the current humidity of the air is greater than the first preset humidity but less than the second preset humidity, the preset purification time is decreased by a fifth purification time to obtain the target purification time; if the current humidity of the air is greater than or equal to a second preset temperature, the preset purification time is increased by a sixth purification time to obtain the target purification time. The sixth purification time is greater than or equal to the fifth purification time. The first preset humidity can be selected as 30%-50%, the second preset humidity can be selected as 50%-70%, the fourth purification time can be selected as 1%-100% of the preset purification time, the fifth purification time can be selected as 1%-33.3% of the preset purification time, and the sixth purification time can be selected as 33.3%-66.7% of the preset purification time. It should be noted that in other embodiments, the preset purification time, the first preset humidity, the second preset humidity, the fourth purification time, the fifth purification time, and the sixth purification time can be set according to the actual situation, and this embodiment does not limit them.

[0093] In one embodiment, the air purifier can obtain a target purification time by jointly adjusting the preset purification time of the air purifier based on the current temperature and humidity of the air. For example, the target purification time can be obtained by obtaining the influence weight of the current temperature and humidity of the air on the purification effect of the air purifier, determining the correction value of the preset purification time based on the influence weight, and adjusting the preset purification time based on the correction value of the preset purification time.

[0094] Step S60: After the magnetic field module runs for the target purification time according to the operating parameters, the purification module and the magnetic field module are turned off.

[0095] In this embodiment, after the air purifier obtains the target purification time, it controls the purification module 3 and the magnetic field module 4 to run for the target purification time. After the purification module 3 and the magnetic field module 4 have run for the target purification time, the purification module 3 and the magnetic field module 4 are turned off, the air purification mode is exited, and the current air purification operation ends.

[0096] In the technical solution provided in this embodiment, at least one of the current air temperature and current humidity is acquired, and the target purification time of the air purifier is determined based on the current temperature and current humidity. After the magnetic field module 4 operates for the target purification time according to the operating parameters, the purification module 3 and the magnetic field module 4 are turned off. This solution, by considering at least one of the air temperature and humidity to determine the purification time of the air purifier, can effectively control the total amount of bactericidal factors released by the purification module 3, ensuring that the total amount of bactericidal factors released is normal. On the one hand, it avoids the situation where the total amount of bactericidal factors produced is too small to achieve the bactericidal effect; on the other hand, it avoids the situation where the total amount of bactericidal factors produced is too large to cause secondary pollution to the indoor environment, thereby improving the air purification effect of the air purifier.
