[0052] At present, when purifying indoor air, an air purification device that can generate negative ions and plasma is usually used. However, when the air purification device purifies the indoor air, the negative ion working area and the plasma working area work at the same time. However, the types of pollutants in the air of the indoor environment are different in different seasons, different regions, and different occasions. The negative ion working area and the plasma working area working at the same time cannot achieve the best purification effect. For example, when the indoor particulate pollutants exceed the standard, negative ions are needed to play a condensation and sedimentation role to remove the particulate matter in the air. At this time, plasma cannot play a role in air purification. For another example, when odor molecules such as aldehydes and amines are generated indoors, plasma is needed to play a role in decomposing the odor molecules and removing the odor. At this time, negative ions alone cannot play a role in air purification. It can be understood that the negative ion working area and the plasma working area working at the same time cannot achieve the best purification effect.

[0053] In a first aspect, an embodiment of the present application provides an air purification control method, which is applied to an air purification device including a plasma generating component and a negative ion generating component. The specific steps are shown in 1. The control method includes:

[0054] S101, the controller obtains the pollutant concentration and relative humidity of pollutants in the air.

[0055] In this embodiment, the sensor group of the air purification device is first used to detect pollutants in the air and the humidity of the air. The controller receives the pollutant concentration and relative humidity detected by the sensor group to determine the pollutant concentration and relative humidity.

[0056] In one example, the sensor group in this embodiment may include a gas sensor, a particle sensor, and a humidity sensor.

[0057] S102, the controller determines the target working state of the plasma generating component and the negative ion generating component according to the pollutant concentration and the relative humidity.

[0058] In this embodiment, after determining the concentration of pollutants and relative humidity in the air, the controller can determine the pollution state of the air according to the concentration of pollutants and relative humidity, and according to the pollution state of the air, can determine the components that need to work in the plasma generating component and the negative ion generating component, so as to determine the working state of the plasma generating component and the negative ion generating component, and can accurately control the air purification device according to the working state of the plasma generating component and the negative ion generating component. Among them, the plasma generating component in this embodiment is used to generate plasma to purify particulate pollutants in the air, and the negative ion generating component is used to generate negative ions to purify gaseous pollutants in the air.

[0059] The air purification control method provided in the embodiment of the present application can obtain the pollutant concentration and relative humidity of pollutants in the air, accurately determine the components that need to work for the plasma generating component and the negative ion generating component under the current pollutant concentration and the current relative humidity, and then accurately determine the working status of the plasma generating component and the negative ion generating component, thereby realizing precise control of the air purification device and improving the air purification effect. At the same time, through precise control of the air purification device, the situation where the plasma generating component or the negative ion generating component cannot purify the air when working is avoided, thereby reducing energy consumption.

[0060] In an exemplary embodiment, see Figure 2 As shown, it is a schematic diagram of the structure of a generator assembly provided in an embodiment of the present application, wherein the plasma generating assembly in this embodiment may include a second discharge electrode 2 and a third discharge electrode 3, there is a voltage difference between the second discharge electrode 2 and the third discharge electrode 3 to form a strong electric field, so that plasma can be generated, wherein the second discharge electrode 2 and the third discharge electrode 3 are both fixed on a base 4. Specifically, the material of the second discharge electrode 2 and the third discharge electrode 3 in this embodiment may be stainless steel, copper, aluminum, tungsten or molybdenum, the shape of the second discharge electrode 2 may be serrated, needle-shaped or conical, and the shape of the third discharge electrode 3 may be a plate-shaped, metal strip-shaped or metal wire-shaped with multiple holes in the middle, wherein the shape of the holes may be circular, square or hexagonal. Specifically, the plasma in this embodiment enters the air through the ion injection hole 5.

[0061] The negative ion generating assembly in this embodiment may include a first discharge electrode 1, which is fixed on a base. A plurality of first discharge electrodes 1 may be provided, for example, two, and the two first discharge electrodes 1 may be symmetrically distributed on both sides of the plasma generating assembly, or may be arranged at intervals on one side of the plasma generating assembly. Specifically, the material of the first discharge electrode 1 may be a carbon fiber bundle, stainless steel, copper, tungsten or molybdenum, and the shape of the first discharge electrode 1 may be a brush-like, needle-like or sawtooth-like.

[0062] In an exemplary embodiment, S102 may include the following steps:

[0063] S1021, the controller determines the target working state according to the gaseous pollutant concentration, the particulate pollutant concentration and the relative humidity.

[0064] In this embodiment, when determining the target working state of the air purification device, the controller obtains the gaseous pollutant concentration and the particulate pollutant concentration in the pollutant concentration, so that the pollutants that need to be purified in the air can be determined by using the gaseous pollutant concentration, the particulate pollutant concentration and the relative humidity, so that the components that need to work in the plasma generating component and the negative ion generating component can be accurately determined according to the pollutants that need to be purified, so as to determine the target state of the plasma generating component and the negative ion component, and then the air purification device can be accurately controlled to improve the air purification effect. Among them, the pollutants in this embodiment can include gaseous pollutants and particulate pollutants.

[0065] In an exemplary embodiment, S1021 may include the following steps:

[0066] S10211, the controller determines a first exceeding-standard result of the gaseous pollutant concentration according to the gaseous pollutant concentration and a first preset standard.

[0067] In this embodiment, after determining the concentration of gaseous pollutants, the controller compares the concentration of gaseous pollutants with a first preset standard to determine whether the concentration of gaseous pollutants exceeds the standard, thereby determining a first exceeding standard result, wherein the first exceeding standard result includes exceeding the standard and not exceeding the standard. When the first exceeding standard result is exceeding the standard, it is determined that the gaseous pollutants need to be purified. When the first exceeding standard result is not exceeding the standard, it is determined that there is no need to purify the gaseous pollutants.

[0068] S10212, the controller determines a second exceeding standard result of the particle pollutant concentration according to the particle pollutant concentration and a second preset standard.

[0069] In this embodiment, after determining the concentration of particulate pollutants, the controller compares the concentration of particulate pollutants with a second preset standard to determine whether the concentration of particulate pollutants exceeds the standard, thereby determining a second exceeding standard result, wherein the second exceeding standard result includes exceeding the standard and not exceeding the standard. When the second exceeding standard result is exceeding the standard, it is determined that the particulate pollutants need to be purified. When the second exceeding standard result is not exceeding the standard, it is determined that the particulate pollutants do not need to be purified.

[0070] S10213, the controller determines a third exceeding-standard result of the relative humidity based on the relative humidity and a third preset standard.

[0071] In this embodiment, after determining the relative humidity, the relative humidity is compared with the third preset standard to determine whether the relative humidity exceeds the standard, thereby determining a third exceeding standard result, wherein the third exceeding standard result includes exceeding the standard and not exceeding the standard. When the third exceeding standard result is exceeding the standard, it is further determined that when the plasma generating component is working, there is a risk of arcing and ignition between the discharge electrodes of the plasma generating component. When the first exceeding standard result is not exceeding the standard, it is further determined that the plasma generating component can work normally.

[0072] S10214, the controller determines the target working state according to the first exceeding standard result, the second exceeding standard result and the third exceeding standard result.

[0073] In this embodiment, after determining the first exceeding standard result, the second exceeding standard result and the third exceeding standard result, the controller determines the target working state according to the first exceeding standard result, the second exceeding standard result and the third exceeding standard result.

[0074] Specifically, when the concentration of gaseous pollutants exceeds the standard, the concentration of particulate pollutants does not exceed the standard, and the relative humidity does not exceed the standard, it is determined that the gaseous pollutants need to be purified, and there is no need to purify the particulate pollutants. The plasma generating component can work normally, and the target working state is determined as the plasma generating component working and the negative ion generating component not working.

[0075] When the concentration of gaseous pollutants does not exceed the standard and the concentration of particulate pollutants exceeds the standard, and / or the concentration of gaseous pollutants does not exceed the standard and the relative humidity exceeds the standard, it is determined that the particulate matter needs to be purified, and there is a risk of arcing and ignition when the plasma generating component is working, and the target working state is determined as the plasma generating component not working and the negative ion generating component working.

[0076] When the concentration of gaseous pollutants exceeds the standard and the concentration of particulate pollutants exceeds the standard but the relative humidity does not exceed the standard, it is determined that the gaseous pollutants need to be purified and the plasma generating component can work normally, and then the target working state is determined as the plasma generating component working and the negative ion generating component working.

[0077] The embodiments of the present application can accurately determine the air pollution conditions and the working environment conditions of the plasma generating component by utilizing the gaseous pollutant concentration, the particulate pollutant concentration and the relative humidity. Then, based on the air pollution conditions and the working environment conditions of the plasma generating component, the components that need to work in the plasma generating component and the negative ion generating component can be determined to accurately control the air purification device. At the same time, by determining the working environment conditions of the plasma generating component, the risk of arcing and ignition during operation of the plasma generating component can be effectively avoided, thereby improving the safety of the air purification device.

[0078] In an exemplary embodiment, S10211 may include the following steps:

[0080] In this embodiment, the formaldehyde concentration of formaldehyde and the volatile organic concentration of volatile organic compounds in the gaseous pollutant concentration are obtained, the formaldehyde concentration is compared with the first preset threshold, and the volatile organic concentration is compared with the second preset threshold. When the formaldehyde concentration is greater than or equal to the first preset threshold, and the volatile organic concentration is greater than or equal to the second preset threshold, the first exceeding standard result is determined to be exceeding the standard. When the formaldehyde concentration is greater than or equal to the first preset threshold, or the volatile organic concentration is greater than or equal to the second preset threshold, the first exceeding standard result is determined to be exceeding the standard. When the formaldehyde concentration is less than the first preset threshold, and the volatile organic concentration is less than the second preset threshold, the first exceeding standard result is determined to be not exceeding the standard. Among them, the gaseous pollutants in this embodiment may include formaldehyde and volatile organic compounds, and the first preset standard may include the first preset threshold and the second preset threshold.

[0081] In an exemplary embodiment, S10212 may include the following steps:

When the first particle pollutant concentration is greater than or equal to the third preset threshold, and the second particle pollutant concentration is greater than or equal to the fourth preset threshold, the second exceeding standard result is determined to be exceeding the standard. When the first particle pollutant concentration is greater than or equal to the third preset threshold, or the second particle pollutant concentration is greater than or equal to the fourth preset threshold, the second exceeding standard result is determined to be exceeding the standard.
