[0002] With the advancement of industrialization and urbanization, air pollution and bacterial problems in our living environment are becoming increasingly serious. Discharge electrode assemblies are components used in particle generators to produce bactericidal and deodorizing particles. Currently, existing discharge electrode assemblies used to produce bactericidal and deodorizing particles typically generate negative oxygen ions.

[0003] However, when the above-mentioned electrode for generating negative oxygen ions is applied to a particle generator, the following technical problems often occur:

[0004] First, when the electrode that produces negative oxygen ions is applied to the particle generator, the electrode that produces negative oxygen ions can only ionize to produce negative oxygen ions. Although the negative oxygen ions have a significant effect on removing PM2.5 particles in the air, their effect on sterilization and deodorization is less significant, and the formaldehyde purification rate is low.

[0005] Furthermore, when the discharge electrode assembly of the present disclosure is applied to a sterilization and deodorization particle generator to purify formaldehyde or PM2.5 particles in the air, the following technical problems further arise:

[0020] The above-described various embodiments of the present disclosure have the following beneficial effects: The discharge electrode assemblies of some embodiments of the present disclosure improve the effectiveness of sterilization and odor removal, as well as the formaldehyde removal rate. Specifically, the low effectiveness of sterilization and odor removal and formaldehyde removal is due to the fact that when an electrode generating negative oxygen ions is used in a particle generator, the electrode generating negative oxygen ions can only ionize and produce negative oxygen ions. While negative oxygen ions are effective in removing PM2.5 particles from the air, their effectiveness in sterilization and odor removal is low, and the formaldehyde removal rate is low.

The second discharge electrode assembly includes a second discharge electrode and a second discharge port electrode. The second discharge port electrode is an annular or spherical electrode located on the central axis of the annular hole or spherical internal through-hole in the second discharge port electrode. The second discharge electrode is used to ionize water in the air to generate second nanoparticles containing hydrogen ions. Thus, the second discharge electrode assembly can be used to generate nanoparticles containing hydrogen ions for sterilization, deodorization, and sedimentation removal of particulate matter such as PM2.5. The third discharge electrode assembly includes a third discharge electrode and a third discharge port. The third discharge electrode assembly is used to ionize oxygen in the air to generate third nanoparticles containing negative oxygen ions. Thus, the third discharge electrode can be used to generate nanoparticles containing negative oxygen ions for sedimentation removal of particulate matter such as PM2.5. The first discharge electrode in the first discharge electrode assembly is connected to one end of the first high-voltage power supply, and the first discharge port electrode in the first discharge electrode assembly is connected to the other end of the first high-voltage power supply. The second discharge electrode and second discharge port electrode in the second discharge electrode assembly are connected to the positive electrode of the second high-voltage power supply, and the third discharge electrode in the third discharge electrode assembly is connected to the negative electrode of the second high-voltage power supply. This is because the discharge electrode assembly not only includes the third discharge electrode for generating nanoparticles containing negative oxygen ions that are used to precipitate and remove particulate pollutants such as PM2.5, but also includes the first discharge electrode assembly and the second discharge electrode assembly.The first discharge electrode assembly is used to generate nanoparticles containing hydroxyl groups and hydrogen peroxide for sterilization, deodorization, and purification of formaldehyde in the air. The second discharge electrode assembly is used to generate nanoparticles containing hydrogen ions for sterilization, deodorization, and sedimentation removal of particulate matter such as PM2.5. Thus, the first, second, and third discharge electrode assemblies enhance the effectiveness of the discharge electrode assemblies in sterilization and deodorization, while the first discharge electrode assembly enhances the formaldehyde purification rate of the discharge electrode assemblies.

[0067] The above technical solution and its related contents, as an inventive point of an embodiment of the present disclosure, solve the second technical problem mentioned in the background technology: "When the discharge electrode assembly of the present disclosure is applied to a sterilization and deodorization particle generator to purify formaldehyde or PM2.5 particles in the air, when the sterilization and deodorization particle generator is usually started, the various discharge electrode assemblies inside the sterilization and deodorization particle generator will be started and powered on at the same time. The simultaneous activation of multiple electrode assemblies will increase the total power demand, resulting in higher power consumption." The factors that lead to higher power consumption are often as follows: When the discharge electrode assembly of the present disclosure is applied to a sterilization and deodorization particle generator to purify formaldehyde or PM2.5 particles in the air, when the sterilization and deodorization particle generator is usually started, the various discharge electrode assemblies inside the sterilization and deodorization particle generator will be started and powered on at the same time. The simultaneous activation of multiple electrode assemblies will increase the total power demand, resulting in higher power consumption. If the above factors are solved, the effect of reducing power consumption can be achieved. To achieve this effect, first, the air quality detection information display screen is controlled to display the formaldehyde concentration detection information and the PM2.5 particle detection information. Thus, formaldehyde concentration detection information and the aforementioned PM2.5 particle detection information can be obtained. Next, in response to determining that the aforementioned formaldehyde concentration detection information includes a formaldehyde concentration value greater than or equal to a preset formaldehyde concentration value, the following formaldehyde purification energy-saving activation steps are performed: First, a first preset voice warning message indicating a high formaldehyde concentration is played to provide a voice warning. Thus, a voice warning is provided when the formaldehyde concentration is high. Second, a first electrode assembly in the aforementioned sterilizing and deodorizing particle generator is connected to a first high-voltage power supply to generate first nano-purification particles via the first electrode assembly. Thus, the first electrode assembly and the first high-voltage power supply can be connected when the formaldehyde concentration is high. Then, the system time is obtained as the current time; then, based on the current time, the following first disconnection step is performed: Sub-step 1: At a first time point after the current time that is a preset interval from the current time, formaldehyde concentration detection information corresponding to the first time point is obtained as the current formaldehyde concentration detection information. Thus, formaldehyde concentration detection information corresponding to the first time point after the current time can be obtained. Sub-step 2: In response to determining that the formaldehyde concentration value in the current formaldehyde concentration detection information is less than a preset formaldehyde concentration value, disconnecting the first high-voltage power supply from the first electrode assembly. This allows for disconnecting the first high-voltage power supply from the first electrode assembly when the formaldehyde concentration drops below the preset formaldehyde concentration value after formaldehyde purification, thereby reducing power consumption. Sub-step 3: In response to determining that the formaldehyde concentration value in the current formaldehyde concentration detection information is greater than or equal to the preset formaldehyde concentration value, reacquiring the system time and updating the acquired system time to the current time to update the current time. Sub-step 4: Re-performing the first disconnection step described above based on the updated current time.Then, in response to determining that the PM2.5 particle concentration value included in the PM2.5 particle detection information is greater than or equal to the preset particle concentration value, the following particle purification energy-saving activation steps are performed: First, a first preset voice warning message indicating a high PM2.5 particle concentration is played to provide a voice warning. This allows for a warning to be issued when the PM2.5 particle concentration value is greater than or equal to the preset particle concentration value. Then, the second and third electrode assemblies in the sterilizing and deodorizing particle generator are controlled to be connected to a second high-voltage power supply, so that second and third nano-purifying particles are generated by the second and third electrode assemblies. This allows for the second and third electrode assemblies to be connected when the PM2.5 particle concentration value is greater than or equal to the preset particle concentration value. Then, the system time is obtained as the current system time. Then, based on the current system time, the following second disconnection step is performed: Then, at a second time point after the current system time that is a preset interval from the current system time, PM2.5 particle detection information corresponding to the second time point is obtained as the current PM2.5 particle detection information. This allows for the acquisition of PM2.5 particle detection information at the second time point that is a preset interval from the current system time. Next, in response to determining that the PM2.5 particle concentration value in the current PM2.5 particle detection information is less than a preset particle concentration value, the second high-voltage power supply is disconnected from the second and third electrode assemblies. This allows the second high-voltage power supply to be disconnected from the second and third electrode assemblies when the PM2.5 particle concentration value decreases to less than the preset particle concentration value, thereby reducing power consumption. Subsequently, in response to determining that the PM2.5 particle concentration value in the current PM2.5 particle detection information is greater than or equal to the preset particle concentration value, the system time is again acquired and updated to the current system time to update the current system time. The second disconnection step is then performed again based on the updated current time. Because different electrode assemblies are connected to the power supply under different circumstances, when the formaldehyde concentration value is greater than or equal to the preset formaldehyde concentration value, the formaldehyde purification energy-saving activation step is performed, connecting the first high-voltage power supply to the first electrode assembly. When the PM2.5 particle concentration value is greater than or equal to the preset particle concentration value, the particle purification energy-saving activation step is performed, connecting the second and third electrode assemblies to the power supply. Connecting different discharge electrode assemblies based on different purification needs reduces the energy consumption caused by activating multiple discharge electrode assemblies simultaneously. Furthermore, after formaldehyde purification, when the formaldehyde concentration drops below a preset formaldehyde concentration, the first high-voltage power supply is promptly disconnected from the first electrode assembly, reducing power consumption. When the PM2.5 particle concentration drops below a preset value, the second high-voltage power supply is promptly disconnected from the second and third electrode assemblies, further reducing energy consumption.

[0068] The above-described various embodiments of the present disclosure have the following beneficial effects: The discharge electrode assemblies of some embodiments of the present disclosure improve the effectiveness of sterilization and odor removal, as well as the formaldehyde removal rate. Specifically, the low effectiveness of sterilization and odor removal and formaldehyde removal is due to the fact that when an electrode generating negative oxygen ions is used in a particle generator, the electrode generating negative oxygen ions can only ionize and produce negative oxygen ions. While negative oxygen ions are effective in removing PM2.5 particles from the air, their effectiveness in sterilization and odor removal is low, and the formaldehyde removal rate is low. Based on this, the discharge electrode assemblies of some embodiments of the present disclosure include: a first discharge electrode assembly, a second discharge electrode assembly, a third discharge electrode assembly, a first high-voltage power supply, and a second high-voltage power supply. The first discharge electrode assembly includes a first discharge electrode and a first discharge port electrode. The first discharge electrode assembly is configured to ionize moisture and oxygen in the air to generate first nano-sized purification particles, wherein the first nano-sized purification particles are nano-sized particles containing hydroxyl groups and hydrogen peroxide. Thus, the first discharge electrode can be used to generate nano-sized particles containing hydroxyl groups and hydrogen peroxide. The nanoparticles containing hydroxyl and hydrogen peroxide can be used for sterilization, deodorization, and purification of formaldehyde in the air. The second discharge electrode assembly includes a second discharge electrode and a second discharge port electrode. The second discharge port electrode is an annular or spherical electrode located on the central axis of the annular hole or spherical internal through-hole in the second discharge port electrode. The second discharge electrode is used to ionize water in the air to generate second nanoparticles containing hydrogen ions. Thus, the second discharge electrode assembly can be used to generate nanoparticles containing hydrogen ions for sterilization, deodorization, and sedimentation removal of particulate matter such as PM2.5. The third discharge electrode assembly includes a third discharge electrode and a third discharge port. The third discharge electrode assembly is used to ionize oxygen in the air to generate third nanoparticles containing negative oxygen ions. Thus, the third discharge electrode can be used to generate nanoparticles containing negative oxygen ions for sedimentation removal of particulate matter such as PM2.5. The first discharge electrode in the first discharge electrode assembly is connected to one end of the first high-voltage power supply, and the first discharge port electrode in the first discharge electrode assembly is connected to the other end of the first high-voltage power supply. The second discharge electrode and second discharge port electrode in the second discharge electrode assembly are connected to the positive electrode of the second high-voltage power supply, and the third discharge electrode in the third discharge electrode assembly is connected to the negative electrode of the second high-voltage power supply. This is because the discharge electrode assembly not only includes the third discharge electrode for generating nanoparticles containing negative oxygen ions that are used to precipitate and remove particulate pollutants such as PM2.5, but also includes the first discharge electrode assembly and the second discharge electrode assembly.The first discharge electrode assembly is used to generate nanoparticles containing hydroxyl groups and hydrogen peroxide for sterilization, deodorization, and purification of formaldehyde in the air. The second discharge electrode assembly is used to generate nanoparticles containing hydrogen ions for sterilization, deodorization, and sedimentation removal of particulate matter such as PM2.5. Thus, the first, second, and third discharge electrode assemblies enhance the effectiveness of the discharge electrode assemblies in sterilization and deodorization, while the first discharge electrode assembly enhances the formaldehyde purification rate of the discharge electrode assemblies.
