[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] According to an embodiment of the present invention, an embodiment of a method for determining the charging efficiency of an electric purification module is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0037] Figure 1 is a schematic diagram of distributed current detection in related technologies, such as Figure 1 As shown, the related technology only detects the total current at the ground end, but the charging efficiency of the electric purification module cannot be studied using only the total current at the ground end.

[0038] In this embodiment, a method for determining the charging efficiency of an electric purification module is provided, which can be used in computer equipment. Figure 2 is a flow chart of a method for determining charging efficiency of an electric purification module according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0039] Step S201: obtaining the current of each sub-area in the charging area of ​​the electric purification module.

[0040] That is to say, the charging area of ​​the electric purification module can be divided into multiple sub-areas, and the current of each sub-area is obtained respectively.

[0041] Step S202: determining the charge distribution of each sub-region according to the current of each sub-region.

[0042] Step S203: Obtain the pollutant distribution in each sub-area.

[0043] Step S204: determining the charging possibility of each sub-region according to the charge distribution of each sub-region and the pollutant distribution of each sub-region.

[0044] Specifically, the charging possibility of the spatial point can be determined according to the overlap between the charging distribution and the pollutant distribution at the same spatial point.

[0045] Step S205: Determine the charging efficiency of the electrical purification module according to the charging possibility of each sub-area.

[0046] The method for determining the charging efficiency of the electric purification module provided in this embodiment can obtain the charge distribution of each sub-area by acquiring the current of each sub-area, and then obtain the charging possibility of each sub-area based on the charge distribution of each sub-area and the pollutant distribution of each sub-area, and further obtain the charging efficiency of each electric purification module, that is, a method for studying the charging efficiency of the electric purification module is provided.

[0047] In this embodiment, a method for determining the charging efficiency of an electric purification module is provided, which can be used in computer equipment. Figure 3 is a flow chart of another method for determining charging efficiency of an electric purification module according to an embodiment of the present invention. Figure 6 FIG. 1 is a flow chart of an example of a method for determining charging efficiency of an electric purification module according to an embodiment of the present invention. Figure 3 and Figure 6 As shown, the process includes the following steps:

[0048] Step S301: obtaining the current of each sub-area in the charging area of ​​the electric purification module.

[0049] Figure 4 is a schematic structural diagram of a vertical section of an electric purification module according to an embodiment of the present invention, Figure 5 yes Figure 4 A partial enlarged view of the electric purification module, such as Figure 4 and Figure 5 As shown in the figure, under the action of electric field force, the charges move in the three-dimensional space formed by high voltage-ground, and the charges are mainly concentrated in five sub-areas, namely HG-0, Hh-0, HG-3, Hh-2 and HG-1, where H represents high voltage, h represents semi-high voltage, G represents ground, and 0 to 3 represent the area number. A high-precision ammeter can be used to detect between each grounding plate and the ground to obtain the current in each sub-area.

[0050] Step S302: determining the charge distribution of each sub-region according to the current of each sub-region.

[0051] In some optional implementations, determining the charge distribution of each sub-region according to the current of each sub-region comprises the following steps:

[0052] Step S3021: Obtain the discharge time of the electric purification module and the velocity distribution function of the discharge charge.

[0053] Step S3022: obtaining the charge distribution of each sub-region according to the current, discharge time, and velocity distribution function of each sub-region.

[0054] For example, the charge distribution can be expressed in the form of a distribution probability function, such as c(x,y,z,t) represents the probability of finding a charge at a spatial point (x,y,z) at time t.

[0055] Step S303: Obtain the pollutant distribution in each sub-area.

[0056] In some optional implementations, obtaining the pollutant distribution of each sub-area includes the following steps:

[0057] Step S3031: Obtain pollutant concentration.

[0058] Step S3032: Determine the pollutant distribution in each sub-area according to the pollutant concentration.

[0059] In an optional implementation, it can be considered that the pollutants are evenly distributed in the air purifier, and the distribution of pollutants in each sub-area is determined based on the pollutant concentration and the characteristics of the even distribution of pollutants.

[0060] For example, the pollutant distribution can be expressed in the form of a distribution probability function, such as g(x, y, z, t) represents the pollutant distribution at a spatial point (x, y, z) at time t.

[0061] Step S304: determining the charging possibility of each sub-region according to the charge distribution of each sub-region and the pollutant distribution of each sub-region.

[0062] In some optional embodiments, determining the charging possibility of each sub-region according to the charge distribution of each sub-region and the pollutant distribution of each sub-region comprises the following steps:

[0063] Step S3041: multiply the charge distribution and pollutant distribution belonging to the same spatial point at the same time to obtain the charge possibility of the same spatial point.

[0064] Step S3042: obtain the charging possibility of the same sub-region by combining the charging possibility of each spatial point in the same sub-region.

[0065] Specifically, the charging possibility of the spatial point can be determined according to the overlap between the charge distribution and the pollutant distribution at the same spatial point. For example, the spatial overlap between the pollutant distribution and the charge distribution during the wind flow is represented by g(x, y, z, t)*c(x, y, z, t), denoted as G(M).

[0066] Step S305: Determine the charging efficiency of the electrical purification module according to the charging possibility of each sub-area.

[0067] It can be understood that the charging probability is proportional to the charging efficiency, that is, the greater the charging probability, the greater the charging efficiency.

[0068] The method for determining the charging efficiency of the electric purification module provided in this embodiment can obtain the charge distribution of each sub-area by acquiring the current of each sub-area, and then obtain the charging possibility of each sub-area based on the charge distribution of each sub-area and the pollutant distribution of each sub-area, and further obtain the charging efficiency of each electric purification module, that is, a method for studying the charging efficiency of the electric purification module is provided.

[0069] Based on the above embodiments, the present invention also provides a method for determining the charging efficiency of an electric purification module, such as Figure 7 The method comprises the following steps:

[0070] Step S701: using the above-mentioned method for determining the charging efficiency of the electrical purification module to obtain a plurality of charging efficiencies.

[0071] Step S702: selecting a maximum value from the multiple charging efficiencies, and using the operating parameters corresponding to the maximum value as the optimal operating parameters of the electrical purification module.

[0072] In other words, during the product development process, parameters that affect the charging efficiency, such as wind speed, structure, and electric potential, can be continuously changed. The above method can be used to obtain the charging efficiency corresponding to each set of parameters, thereby seeking the optimal charging parameters. This can greatly improve efficiency, shorten development time, and reduce trial and error costs.
