Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of air purification technology, and particularly to a triplet particle generator and an air purification method. Background Art

[0002] The air is purified by a particle generator, and the ionized ions can disinfect bacteria in the air and remove formaldehyde and odors in the air. Currently, when purifying the air with a particle generator, the commonly used method is to use a nano water ionizer or a negative ion generator to ionize the air to purify the air.

[0003] However, it has been found in practice that when the above method is used to purify the air, the following technical problems often occur: when the air is purified by a nano water ion generator, negative oxygen ions cannot be electrolyzed, and there are insufficient negative oxygen ions in the air, which cannot remove particulate pollutants such as PM2.5 in the air, resulting in low air quality; when a negative ion generator is used, a large amount of negative oxygen ions are ionized, which cannot sterilize and deodorize the air, and a large amount of negative oxygen ions will cause strong electrostatic interference indoors.

[0004] In the process of adopting technical solutions to solve the above-mentioned technical problem 1, the following problems often arise: Technical problem 2: The indoor space may be large, resulting in insufficient release of the first nanoparticles containing hydroxyl and / or hydrogen peroxide. In response to these problems in the above-mentioned technical problem 2, the conventional solution is generally to increase the power of the nano water ion generator. However, the above-mentioned conventional solution still has the following problems: the total power of the triplet particle generator is fixed, and increasing the power of the nano water ion generator results in insufficient ionized negative oxygen ions, which in turn fails to remove particulate pollutants such as PM2.5 in the air, resulting in low air quality.

[0005] In the process of adopting technical solutions to solve the above-mentioned technical problem one, the following problems often arise: Technical problem three: the negative oxygen ions generated by ionizing the oxygen in the air will gather the dust in the air around the generator, creating a black wall effect, and the dust will block the particle release position of the generator, reducing the particle release rate, and the generator will bring dust into the air when working, which may be inhaled by the user, affecting the user's health. In response to these problems in the above-mentioned technical problem three, the conventional solution is generally to reduce the power of the negative ion generator. However, the above-mentioned conventional solution still has the following problems: reducing the power of the negative ion generator will reduce the concentration of negative oxygen ions, and the hydrogen ions in the air will neutralize and offset the negative oxygen ions, resulting in a low concentration of negative oxygen ions in the air, and unable to remove particulate pollutants such as PM2.5 in the air, resulting in low air quality.

Specifically, the reasons for the low indoor air quality and the electrostatic interference caused by high concentrations of negative oxygen ions are: when the air is purified by the nano water ion generator, negative oxygen ions cannot be electrolyzed, and the negative oxygen ions in the air are insufficient, and particulate pollutants such as PM2.5 in the air cannot be removed, resulting in low air quality; and when using a negative ion generator, a large amount of negative oxygen ions are ionized, which cannot sterilize and deodorize the air, and a large amount of negative oxygen ions will cause strong electrostatic interference in the room.

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Figure 1 Schematic diagram of the structure of some embodiments of the triplet particle generator according to the present disclosure. Figure 1 It includes a first particle generator 1, a first discharge electrode 11, a first electrode needle 111, a water-absorbing material 112, a thermoelectric conversion material 113, a first substrate 114, a first release electrode 12, a first release port 121, a first wiring member 122, a second particle generator 2, a second discharge electrode 21, a second release electrode 22, a second release port 221, a second wiring member 222, a third particle generator 3, a third discharge electrode 31, a third release port 32, a first high-voltage power supply 4, a second high-voltage power supply 5, an encapsulating shell 6, a first through hole 61, a second through hole 62 and a third through hole 63.

[0028] In some embodiments, the first particle generator 1 comprises a pair of electrodes spaced apart from each other, including a first discharge electrode 11 and a first emission electrode 12, which are used to ionize moisture and oxygen in the air to produce first nanoparticles containing hydroxyl radicals and / or hydrogen peroxide. The end of the first discharge electrode 11 closest to the first emission electrode 12 is the first discharge end, and the other end is the enhancement end. At least a portion of the first discharge end is composed of a water-absorbing material 112 to absorb and accumulate moisture from the air. At least a portion of the enhancement end is composed of a thermoelectric conversion material 113, which utilizes the mutual conversion effect between heat and electricity to generate an internal electric field under the action of the external temperature difference thermoelectric effect, ionizing the surrounding moisture to produce oxygen-containing free radicals such as hydroxyl radicals (·OH). The first emission electrode 12 is annular or spherical, formed from stainless steel, titanium, copper, aluminum, silver, or alloys thereof, with a first emission port 121 extending through its center. The first discharge electrode 11 is positioned on the central axis of the first discharge port 121 and is electrically connected to the low-voltage terminal of the first high-voltage power supply 4 via the first electrode needle 111 or the first substrate 114. The first discharge electrode 12 is electrically connected to the high-voltage terminal of the first high-voltage power supply 4 via the first connector 122. This causes the first discharge electrode 11 to ionize surrounding water and oxygen, generating first nanoparticles that are released from the first discharge port 121. The first electrode needle 111 is electrically connected to the water-absorbing material 112 and partially penetrates the water-absorbing material 112 to support and secure it. The thermoelectric conversion material 113 is electrically connected to the first electrode needle 111 and the first substrate 114 at both ends, respectively. The first substrate 114 can be made of metal, a PCB, or a copper-clad ceramic material.

[0029] In some embodiments, the second particle generator 2 is composed of a pair of electrodes spaced apart from each other, including a second discharge electrode 21 and a second release electrode 22. The end of the second discharge electrode 21 close to the second release electrode 22 is a second discharge end.

[0030] In some optional implementations of some embodiments, the second discharge electrode 22 is annular or spherical and is formed from stainless steel, titanium, copper, aluminum, silver, or alloys thereof, with a second discharge port 221 extending through the center thereof. The second discharge electrode 21 is positioned on the central axis of the second discharge port 221 and is electrically connected to the low voltage terminal of the second high-voltage power supply 5. The second discharge electrode 22 is electrically connected to the positive high voltage terminal of the second high-voltage power supply 5 via a second wiring member 222, thereby causing the second discharge electrode 21 to ionize surrounding water to generate second nanoparticles, which are then released from the second discharge port 221.

[0031] The relevant content of steps 1-5 described above, as an inventive feature of the present disclosure, addresses the second technical problem mentioned in the background art: "Indoor space may be large, resulting in insufficient first nanoparticles containing hydroxyl groups and / or hydrogen peroxide being released." Factors contributing to insufficient first nanoparticles containing hydroxyl groups and / or hydrogen peroxide being released are often as follows: Indoor space may be large, resulting in insufficient first nanoparticles containing hydroxyl groups and / or hydrogen peroxide being released. Addressing these factors can prevent insufficient first nanoparticles containing hydroxyl groups and / or hydrogen peroxide being released. To achieve this, some embodiments of the present disclosure utilize materials such as stainless steel, titanium, copper, aluminum, silver, and alloys thereof. Consequently, under the action of a high-voltage electric field, the second discharge electrode self-ionizes to produce nanoparticles of platinum, titanium, silver, copper, or iron-based catalysts. These catalysts cooperate with the first discharge electrode to self-ionize to produce nanoparticles of carbon-based catalysts, thereby electrocatalyzing the in-situ synthesis of hydroxyl groups and / or hydrogen peroxide in air, thereby preventing insufficient first nanoparticles containing hydroxyl groups and / or hydrogen peroxide being released.

[0032] In some embodiments, the third particle generator 3 comprises a third discharge electrode 31 and a third discharge port 32, which are spaced apart from each other. The end of the third discharge electrode 31 closest to the third discharge port 32 serves as a third discharge end. The third discharge port 32 is a through-hole in the shape of a ring or sphere and can be formed from a conductive or non-conductive material. The third discharge electrode 31 is positioned on the central axis of the third discharge port 32 and is electrically connected to the negative high voltage terminal of the second high-voltage power supply 5. This causes the third discharge electrode 31 to ionize the surrounding oxygen, generating third nanoparticles that are released from the third discharge port 32.

[0033] In some embodiments, the positive high-voltage terminal of the second high-voltage power supply 5 is electrically connected to the second release electrode 22, and the negative high-voltage terminal of the second high-voltage power supply 5 is electrically connected to the third discharge electrode 31. That is, the same high-voltage power supply can simultaneously drive the second particle generator 2 and the third particle generator 3. This reduces the number of high-voltage power supplies and allows for dynamic control of the intermittent release and release amount of the second and third nanoparticles to better coordinate the scientific concentration combination of the various nanoparticle components.

[0034] In some embodiments, the first particle generator 1, the second particle generator 2, and the third particle generator 3 are spaced apart from each other, with the distance between the third particle generator 3 and the first particle generator 1 being greater than the distance between the third particle generator 3 and the second particle generator 2. This arrangement not only prevents the negative oxygen ions released by the third particle generator 3 from interfering with the first particle generator 1, thereby facilitating the generation of first nanoparticles, but also avoids premature neutralization between the negative oxygen ions and the hydrogen ions generated by the second particle generator 2, thereby facilitating the release of second nanoparticles and enhancing the purification capabilities of the device for sterilization, deodorization, and sedimentation removal of particulate matter such as PM2.5.

[0035] In some embodiments, the packaging shell 6 is used to accommodate the first particle generator 1, the second particle generator 2 and the third particle generator 3, and corresponding through holes are provided, namely the first through hole 61, the second through hole 62 and the third through hole 63, to release the first nanoparticles, the second nanoparticles and the third nanoparticles, and form ventilation or circulation with the surrounding air under the action of natural diffusion or mechanical ventilation, so as to accelerate the formation, release and dynamic regulation of triplet particles.

[0036] Optionally, the water-absorbing material is a carbon-based material, and the thermoelectric conversion material is a P and / or N-type bismuth telluride semiconductor material.

[0037] Optionally, the water-absorbing material includes carbon fibers, carbon felt, carbon nanotubes, and oxides thereof. Here, under the action of the high-voltage electric field, the first discharge electrode 11 itself ionizes to produce nanoparticles of carbon-based catalysts, thereby electrocatalyzing the in-situ synthesis of hydroxyl radicals and / or hydrogen peroxide in the air, thereby increasing the concentration of the first nanoparticles in the air.

[0038] Optionally, the water-absorbing material 112 may be mixed with calcium chloride, sodium hydroxide, potassium hydroxide, sodium sulfate, potassium sulfate, sodium bisulfate, sodium carbonate, sodium bicarbonate and other water-absorbing materials to further enhance its water-absorbing performance.

[0039] Optionally, at least a portion of the second discharge end is composed of platinum, titanium, silver, copper, iron, their alloys, or oxides, and at least a portion of the third discharge end is composed of platinum or silver, or their alloys. Here, under the action of a high-voltage electric field, the second discharge electrode 21 itself ionizes to produce nanoparticles of platinum, titanium, silver, copper, or iron-based catalysts, which cooperate with the first discharge electrode 11 to self-ionize to produce nanoparticles of carbon-based catalysts, thereby electrocatalyzing the in-situ synthesis of hydroxyl radicals and / or hydrogen peroxide in air. Under the action of a high-voltage electric field, the third discharge electrode 31 itself ionizes to produce nanoparticles of platinum or silver ions, enhancing the sterilization and disinfection effect.

[0040] The first nanoparticles containing hydroxyl groups and / or hydrogen peroxide generated by the first particle generator 1, the second nanoparticles containing hydrogen ions generated by the second particle generator 2, and the third nanoparticles containing negative oxygen ions generated by the third particle generator 3 are mixed by free diffusion or forced convection to form triplet particles. At the same time, the configuration of the second high-voltage power supply 5 and the electrocatalytic material can dynamically adjust the composition and concentration of each particle in the triplet particles, in order to achieve more ecological concentration coupling and health effects.

[0041] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the triplet particle generator of some embodiments of the present disclosure, the indoor air quality is improved, and the problem of electrostatic interference caused by high concentrations of negative oxygen ions is avoided. Specifically, the reasons for the low indoor air quality and the electrostatic interference caused by high concentrations of negative oxygen ions are: when the air is purified by the nano water ion generator, negative oxygen ions cannot be electrolyzed, and the negative oxygen ions in the air are insufficient, and particulate pollutants such as PM2.5 in the air cannot be removed, resulting in low air quality; and when using a negative ion generator, a large amount of negative oxygen ions are ionized, which cannot sterilize and deodorize the air, and a large amount of negative oxygen ions will cause strong electrostatic interference in the room. Based on this, some embodiments of the triplet particle generator disclosed herein include: a first particle generator, a second particle generator, a third particle generator, and a packaging shell, wherein the first particle generator is composed of a pair of electrodes arranged oppositely and spaced apart, including a first discharge electrode and a first release electrode, for ionizing moisture and oxygen in the air to generate first nanoparticles containing hydroxyl groups and / or hydrogen peroxide; the second particle generator is composed of a pair of electrodes arranged oppositely and spaced apart, including a second discharge electrode and a second release electrode, for ionizing moisture in the air to generate second nanoparticles containing hydrogen ions; the third particle generator is composed of a pair of electrodes arranged oppositely and spaced apart, including a second discharge electrode and a second release electrode, for ionizing moisture in the air to generate second nanoparticles containing hydrogen ions; It is composed of a single electrode, including a third discharge electrode and a third release port, and is used to ionize oxygen in the air to generate third nanoparticles containing negative oxygen ions; the above-mentioned third particle generator is arranged at intervals from the above-mentioned second particle generator and the first particle generator, and the distance between the above-mentioned third particle generator and the above-mentioned first particle generator is greater than the distance between the above-mentioned third particle generator and the above-mentioned second particle generator; the above-mentioned packaging shell is used to accommodate the above-mentioned first particle generator, the above-mentioned second particle generator and the above-mentioned third particle generator, and is correspondingly provided with through holes to release the first nanoparticles, the second nanoparticles and the third nanoparticles, and to exchange or circulate with the surrounding air.Because a triplet particle generator is used, hydroxyl and / or hydrogen peroxide are synthesized in situ by ionizing moisture in the air, that is, the concentration of the first nanoparticles is continuously and dynamically increased, and the second particle generator ionizes to produce nano-particle-sized platinum, titanium, silver, copper or iron-based catalysts, which cooperate with the first discharge electrode to ionize itself to produce nano-particle-sized carbon-based catalysts to further electrocatalytically synthesize hydroxyl and / or hydrogen peroxide in situ in the air, that is, continuously and dynamically increase the concentration of the first nanoparticles. The third particle generator ionizes to produce nano-particle-sized platinum or silver ions to increase the sterilization and disinfection effect, and ionizes oxygen in the air to generate negative oxygen ions. Under the synergistic action of the above-mentioned carbon-based catalysts and platinum, titanium, silver, copper or iron-based catalysts, the second nanoparticles containing hydrogen ions and the third nanoparticles containing negative oxygen ions electrocatalytically synthesize hydroxyl and / or hydrogen peroxide in situ in the air, that is, continuously and dynamically increase the concentration of the first nanoparticles, further enhancing its sterilization, disinfection, formaldehyde removal and deodorization effects. Also, because the concentration of the third nanoparticles containing negative oxygen ions is reduced, the problem of electrostatic interference caused by a high concentration of negative oxygen ions is avoided.

[0042] Further references Figure 2 , shows a process 200 of some embodiments of the air purification method according to the present disclosure. The air purification method is applied to Figure 1 The triplet particle generator shown includes the following steps:

[0043] Step 201 : In response to detecting a start-up operation on a triplet particle generator, determining a generator start-up time.

[0044] In some embodiments, an execution entity (e.g., a computing chip) of the air purification method may determine a generator startup time in response to detecting a startup operation on the triplet particle generator. The startup operation may be powering on the triplet particle generator. The generator startup time may be the time when the triplet particle generator is powered on.

[0045] Step 202 : Controlling a first particle generator to start up to ionize moisture and oxygen in the air to obtain first nanoparticles.

[0046] In some embodiments, the execution entity may control the first particle generator to start up, so as to ionize moisture and oxygen in the air to obtain first nanoparticles.

[0047] Step 203: Control the second particle generator to start up to ionize moisture in the air to obtain second nanoparticles.

[0049] Step 204: Determine whether the current time meets the preset start condition.

[0050] In some embodiments, the execution entity may determine whether the current time satisfies a preset start condition.

[0051] In practice, you can determine whether the current time meets the preset start conditions by following the steps below:

[0052] The first step is to determine the current time point corresponding to the current time.

[0053] The second step is to determine the startup duration between the current time point and the generator startup time. In practice, the current time point and the generator startup time can be used as the starting point and end point of the target time period, and the duration represented by the target time period can be used as the startup duration.

[0054] The third step is to determine whether the current time satisfies the preset start condition in response to the start duration being greater than or equal to the preset start duration, wherein the preset start duration may be a pre-set duration for starting the triplet particle generator.

[0055] In the fourth step, in response to the startup duration being less than the preset startup duration, it is determined that the current time does not meet the preset startup condition.

[0056] Step 205 : In response to the current time satisfying the preset start condition, the third particle generator is controlled to start up to ionize oxygen in the air to obtain third nanoparticles.

The nanoparticle concentration in the at least one nanoparticle concentration corresponds to a particle name.

[0061] In the second step, for each nanoparticle concentration in the above nanoparticle concentration information, the following processing steps are performed:

[0062] The first processing step is to determine the comparative relationship information between the above-mentioned nanoparticle concentration and the corresponding particle concentration range.

[0063] In some embodiments, the execution entity may determine comparative relationship information between the nanoparticle concentration and the corresponding particle concentration range. The comparative relationship information may be information generated by comparing the nanoparticle concentration with the corresponding particle concentration range. For example, the comparative relationship information may include: the nanoparticle concentration is less than the corresponding particle concentration range, the nanoparticle concentration is within the corresponding particle concentration range, and the nanoparticle concentration is greater than the corresponding particle concentration range. In practice, the particle concentration range may be obtained from the target database via a wired or wireless connection.

[0064] The second processing step is to reduce the current of the particle generator corresponding to the nanoparticle concentration in response to the first relationship information representing the comparison relationship.

[0065] In some embodiments, the execution entity may reduce the current of the particle generator corresponding to the nanoparticle concentration in response to the first relationship information representing the comparison relationship, wherein the first relationship information may represent that the nanoparticle concentration is greater than the corresponding particle concentration range.

[0066] The third processing step is to increase the current of the particle generator corresponding to the nanoparticle concentration in response to the second relationship information representing the comparison relationship.

[0067] In some embodiments, the execution entity may increase the current of the particle generator corresponding to the nanoparticle concentration in response to second relationship information representing the comparison relationship, wherein the second relationship information may be information indicating that the nanoparticle concentration is less than the corresponding particle concentration range.

[0068] Optionally, after step 205, the following steps are further included:

[0069] The first step is to obtain at least one piece of nanoparticle concentration information collected by the nanoparticle monitoring device to obtain a nanoparticle concentration information set.

[0070] In some embodiments, the execution entity may obtain at least one piece of nanoparticle concentration information collected by the nanoparticle monitoring device to obtain a nanoparticle concentration information set.

[0071] In the second step, clustering is performed on the concentrations of the nanoparticles included in the above nanoparticle concentration information to generate clustered particle concentration groups.

[0072] In some embodiments, the execution entity may perform clustering processing on the nanoparticle concentrations included in the nanoparticle concentration information to generate clustered particle concentration groups. The clustering processing may include clustering the nanoparticle concentrations corresponding to the same particle name to generate the clustered particle concentration groups.

[0073] In the third step, for each clustered particle concentration group in the above clustered particle concentration group set, the following prediction steps are performed:

[0074] In the first prediction step, the clustered particle concentrations in the clustered particle concentration group are sorted to generate a clustered particle concentration sequence.

[0075] In some embodiments, the execution entity may sort the clustered particle concentrations in the clustered particle concentration group to generate a clustered particle concentration sequence. Each clustered particle concentration in the clustered particle concentration sequence has a corresponding acquisition time, and the duration between the acquisition times corresponding to each two adjacent clustered particle concentrations is equal. In practice, the clustered particle concentrations may be sorted in ascending order according to their corresponding acquisition times.

[0076] In the second prediction step, the particle release rate corresponding to every two adjacent clustered particle concentrations in the above clustered particle concentration sequence is determined to obtain a particle release rate sequence.

[0077] In some embodiments, the execution entity may determine the particle release rate corresponding to each two adjacent post-clustering particle concentrations in the post-clustering particle concentration sequence to obtain a particle release rate sequence. In practice, first, the duration between the two acquisition times corresponding to the two adjacent post-clustering particle concentrations is determined as the release duration. Second, the difference between the two post-clustering particle concentrations is determined as the particle concentration change value. Third, the particle release amount is determined based on the above-mentioned particle concentration change value. In practice, the product of the above-mentioned particle concentration change value and the total amount of air particles may be determined as the particle release amount. Here, the total amount of air particles may be determined by a dust particle counter. The above-mentioned total amount of air particles may be the number of particles per unit air. Fourth, the ratio of the above-mentioned particle release amount to the above-mentioned release duration is determined as the particle release rate.

[0078] In a third prediction step, the particle release rate sequence, the collection time group corresponding to the particle release rate sequence, and the preset stop speed are input into a pre-trained time prediction model to obtain a first prediction result.

[0079] In some embodiments, the execution entity may input the particle release rate sequence, the corresponding acquisition time group, and the preset stop speed into a pre-trained time prediction model to obtain a first prediction result. The time prediction model may be a convolutional neural network model that takes the particle release rate sequence, the corresponding acquisition time group, and the preset stop speed as input and outputs the first prediction result. The first prediction result may represent the time point at which the particle release rate reaches the preset stop speed.

[0080] In the fourth prediction step, a preset number of clustered particle concentrations are selected from the clustered particle concentration sequence as a target particle concentration sequence.

[0081] In some embodiments, the execution entity may select a preset number of clustered particle concentrations from the clustered particle concentration sequence as the target particle concentration sequence. The preset number may be a pre-set number of clustered particle concentrations selected from the clustered particle concentration sequence that are closest to the current time.

[0082] The fifth prediction step is to determine the concentration variance value corresponding to each target particle concentration in the target particle concentration sequence.

[0083] In some embodiments, the execution entity may substitute the concentration variance value corresponding to each target particle concentration into the variance formula to obtain the concentration variance value;

[0084] The sixth prediction step is to generate a predicted concentration value according to the concentration variance value and the preset stop speed.

[0085] In some embodiments, the execution entity may generate a predicted concentration value based on the concentration variance value and the preset stopping speed. In practice, first, the particle release rate corresponding to the concentration variance value may be determined. Second, based on the preset stopping speed and the particle release rate value, the predicted concentration value corresponding to the preset stopping speed may be determined.

[0086] In the sixth prediction step, a predicted collection time corresponding to a preset stop speed is determined according to the predicted concentration value as a second prediction result.

[0087] In some embodiments, the execution entity may determine a predicted collection time corresponding to a preset stop speed based on the predicted concentration value.

[0088] In the seventh prediction step, the sum of the product of the first prediction result and the first weight and the product of the second prediction result and the second weight is determined as the second prediction result.

[0089] In some embodiments, the execution entity may determine the sum of the product of the first prediction result and the first weight and the product of the second prediction result and the second weight as the second prediction result. The first weight and the second weight are pre-set weights, and there is no limitation on the setting of the first weight and the second weight, which may be weights obtained through experiments.

[0090] The fourth step is to select the prediction result that meets the preset prediction result conditions from the generated prediction results as the target prediction result.

[0091] In some embodiments, the execution entity may select a prediction result that satisfies a preset prediction result condition from among the generated prediction results as the target prediction result, wherein the preset prediction result condition may be that the time point represented by the prediction result is the earliest.

[0092] The fifth step is to control the triplet particle generator to stop running according to the target prediction result, and control the associated alarm equipment to perform the generator stop alarm operation.

[0093] In some embodiments, based on the target prediction result, the triplet particle generator is controlled to cease operation, and the associated alarm device is controlled to perform an alarm operation to stop the generator operation. In practice, in response to the current time being a time point represented by the target prediction result, the triplet particle generator is controlled to cease operation, and the associated alarm device is controlled to perform an alarm operation to stop the generator operation. The alarm operation to cease may involve controlling the alarm device to operate. The alarm device may be an associated lighting device. The alarm operation to cease may involve controlling the lighting device to illuminate red.

[0094] The relevant content of steps 1-5 described above, as an inventive feature of this disclosure, addresses the third technical problem mentioned in the background art: "Negative oxygen ions generated by ionizing oxygen in the air gather dust in the air around the generator, creating a black wall effect. Dust can also block the generator's particle release point, slowing particle release. During operation, the generator introduces dust into the air, potentially causing users to inhale it and impacting their health." Factors that often impact user health include the following: Negative oxygen ions generated by ionizing oxygen in the air gather dust in the air around the generator, creating a black wall effect. Dust can also block the generator's particle release point, slowing particle release. During operation, the generator introduces dust into the air, potentially impacting user health. Resolving these factors can prevent impacts on user health. To achieve this, first, at least one nanoparticle concentration information item collected by the nanoparticle monitoring device is obtained to generate a nanoparticle concentration information set. This information can then be used to determine the concentrations of various nanoparticles in the air. Second, the individual nanoparticle concentrations included in the nanoparticle concentration information are clustered to generate clustered particle concentration groups. Thus, the particle concentration of each nanoparticle at different acquisition times can be determined. Third, for each clustered particle concentration group in the clustered particle concentration group set, the following prediction steps are performed: First, the clustered particle concentrations in the clustered particle concentration group are sorted to generate a clustered particle concentration sequence. This allows the concentration variation of each nanoparticle to be determined. Second, the particle release rate corresponding to each pair of adjacent clustered particle concentrations in the clustered particle concentration sequence is determined to generate a particle release rate sequence. This allows the release rate variation of the nanoparticles to be determined. Then, the particle release rate sequence, the acquisition time group corresponding to the particle release rate sequence, and the preset stop speed are input into a pre-trained time prediction model to obtain a first prediction result. This allows the first prediction result to be determined. Next, a preset number of clustered particle concentrations are selected from the clustered particle concentration sequence as a target particle concentration sequence. This allows the particle concentration closest to the current time to be selected. Finally, the concentration variance corresponding to each target particle concentration in the target particle concentration sequence is determined; and based on the concentration variance, a predicted concentration value is generated. This allows the determination of the particle concentration in the air when the particle release rate reaches the preset stop speed. Subsequently, the target particle concentration whose corresponding collection time is closest to the collection time corresponding to the predicted concentration value is selected from the target particle concentration sequence. Based on the target particle concentration and the predicted concentration value, a predicted release rate is generated as a second prediction result. The sum of the product of the first prediction result and the first weight and the product of the second prediction result and the second weight is determined as the second prediction result. This allows the prediction of the time point at which the nanoparticle release rate will decrease to the preset stop speed.Fourth, a prediction result that satisfies a preset prediction result condition is selected from the generated prediction results as the target prediction result. This allows the earliest time point at which the preset stop speed is reached to be selected. Fifth, based on the target prediction result, the triplet particle generator is controlled to stop operating, and the associated alarm device is controlled to perform a generator stop alarm operation. Thus, when the preset stop time is reached, the triplet particle generator is stopped, thereby preventing dust adhering to the surface of the triplet particle generator from being introduced into the air, thereby preventing the user from inhaling the dust and thus preventing any health risks to the user.

[0095] The above-described embodiments of the present disclosure have the following beneficial effects: The air purification methods of some embodiments of the present disclosure improve air quality and avoid the situation in which strong static electricity interference indoors caused by excessive negative oxygen ions. Specifically, the poor air quality and strong static electricity caused by excessive negative oxygen ions are caused by: when using a nano water ionizer for air purification, the negative oxygen ions cannot be electrolyzed, resulting in insufficient negative oxygen ions in the air and inability to remove particulate pollutants such as PM2.5 from the air, resulting in poor air quality; while when using a negative ion generator, a large amount of negative oxygen ions is ionized, which is unable to sterilize and deodorize the air, and the large amount of negative oxygen ions causes strong static electricity interference indoors. Based on this, the air purification methods of some embodiments of the present disclosure first determine the generator startup time in response to detecting a startup operation acting on the triplet particle generator. This can determine the startup time of the particle generator. Secondly, the first particle generator is controlled to start to ionize water and oxygen in the air to produce first nanoparticles. This allows the ionization of moisture and oxygen in the air to generate first nanoparticles containing hydroxyl groups and / or hydrogen peroxide, thereby sterilizing and deodorizing the air. The second particle generator is then controlled to activate to ionize moisture in the air, producing second nanoparticles. This allows the ionization of second nanoparticles containing hydrogen ions. Finally, a determination is made as to whether the current time meets a preset activation condition. In response to the current time satisfying the preset activation condition, the third particle generator is controlled to activate to ionize oxygen in the air, producing third nanoparticles. This allows the third particle generator to be activated a period of time after the first and second particle generators have been activated, thereby avoiding the situation where excessive negative oxygen ions can cause strong static electricity interference in the room. Simultaneously, under the synergistic action of the carbon-based catalyst and a platinum, titanium, silver, copper, or iron-based catalyst, the second nanoparticles containing hydrogen ions and the third nanoparticles containing negative oxygen ions can be electrocatalytically synthesized in situ in the air into active substances such as hydroxyl groups and / or hydrogen peroxide, which have longer lifespans. This enhances the air sterilization, disinfection, and formaldehyde removal and deodorization effects.
