Description

[0001] This application claims priority to Chinese Patent Application No. 2023110607363, filed on August 22, 2023, entitled "Air Purification Equipment and Control Method, Apparatus and Storage Medium Thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of air purification technology, and more specifically, to an air purification device and its control method, apparatus and storage medium. Background Technology

[0003] In related technologies, air purifiers can adsorb pollutants in the air by using the electric field generated after being powered on, thereby achieving the purpose of air purification.

[0004] However, in actual operation, the polarization ability of the electric field on pollutants is limited. Some pollutants will still fail to be successfully polarized or the Coulomb force on the polarized pollutants will not meet the standard, resulting in technical problems such as insufficient pollutant capture capacity and poor purification effect of air purifiers. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] Therefore, the first aspect of the present invention provides an air purification device.

[0007] A second aspect of the present invention provides a control method for an air purification device.

[0008] A third aspect of the present invention provides a control device for an air purification device.

[0009] A fourth aspect of the present invention provides a control device for an air purification device.

[0010] A fifth aspect of the present invention provides a readable storage medium.

[0011] The sixth aspect of the present invention provides an air purification device.

[0012] In view of the above, a first aspect of the present invention provides an air purification device, the air purification device comprising: a dust collection assembly, the dust collection assembly including a dust collection surface, the dust collection assembly being capable of generating an electric field when energized, the dust collection surface being used to collect pollutants in the air through the electric field; and a discharge component being used to discharge to the area facing the dust collection surface; wherein the dust collection assembly is used to connect to one of a positive electrode and a negative electrode, and the discharge component is used to connect to the other of a positive electrode and a negative electrode.

[0013] This application defines an air purification device for treating pollutants in the air to reduce the concentration of pollutants in the air. The air purification device includes a dust collection component.

[0014] The dust collection component includes a collection surface that is exposed to the air. When energized, the component accumulates ions, which generate an electric field. This electric field forms a region on the front of the dust collection component. Pollutants within this region are polarized and move towards the collection surface under the influence of Coulomb forces until they are adsorbed onto the surface. This adsorption reduces the concentration of pollutants within the electric field region. Due to the concentration difference, pollutants outside the electric field region migrate to the lower concentration region, thereby reducing the overall concentration of pollutants in the environment and achieving air purification.

[0015] In addition, the air purification device also includes a discharge component. The discharge end of the discharge component releases ions into the area facing the dust collection surface. These released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component. One of the positive and negative electrodes of the power supply component is connected to the dust collection assembly, and the other is connected to the discharge component, so that the ions accumulated inside the dust collection assembly and the ions released by the discharge component have opposite polarities.

[0016] The ions released by the discharge component attach to pollutants in the electric field region, causing the pollutants to carry an opposite charge to the dust collection component. This increases the adsorption force of the dust collection component on top of the original Coulomb force, accelerating the movement of pollutants towards the collection surface and thus enhancing the adsorption capacity of the dust collection component. This compensates for the shortcomings of electric field adsorption and solves the technical problems of insufficient Coulomb force on pollutants, inadequate pollutant capture capacity, and poor purification effect in related technologies. This optimizes the structure of air purification equipment, improves its purification capacity, and enhances the user experience. Simultaneously, the ions released by the discharge component also have a bactericidal effect, reducing the content of toxic substances in the air and protecting user health.

[0017] Based on this, the dust collection component proposed in this application collects pollutants through an electric field. The collected pollutants adhere to the dust collection surface, and can be removed by washing or wiping the surface after use, eliminating the need for frequent filter replacements and reducing the operating cost of the air purification equipment. At the same time, the dust collection component generates relatively low noise when powered on, further enhancing the user experience.

[0018] Specifically, the dust collection component proposed in this application can actively adsorb pollutants in the air by means of its own generated electric field, without relying on circulating airflow to achieve air purification function, thereby saving the space for arranging air ducts and fans, and providing convenient conditions for the miniaturization and lightweight design of air purification equipment.

[0019] Specifically, the dust collection component and the discharge component can be separate structures, with independent power supplies for both. Their positions can be freely adjusted according to the specific requirements of the application scenario. During use, the dust collection component is first positioned, and then the discharge component is placed within the electric field area generated by the dust collection component to ensure that the discharge component can effectively cooperate with the dust collection component to adsorb pollutants from the air.

[0020] Specifically, the dust collection assembly and the discharge component can be an integrated structure, such as directly connecting the dust collection assembly and the discharge component, or fixing the dust collection assembly and the discharge component together on the same base. In this integrated structure, the relative positions of the dust collection assembly and the discharge component are locked, which can ensure that the discharge component can discharge into the electric field region generated by the dust collection assembly.

[0021] The pollutants mentioned in this application are mainly particulate pollutants, including dust, smoke, particulate matter, bacteria, and viruses in the air. They vary in diameter and can generally be classified into the following categories according to their diameter:

[0022] Visible particulate matter: Particulate matter with a diameter of 10 micrometers or less can be seen, such as dust, pollen, and human skin flakes.

[0023] Fine particulate matter: Particulate matter with a diameter of 2.5 micrometers or less, which cannot be seen with the naked eye, but has a significant impact on human health, such as automobile exhaust and factory exhaust.

[0024] Ultrafine particles: Particles with a diameter of 0.1 micrometers or less, which cannot be seen with the naked eye, but can penetrate deep into the human respiratory tract and have a greater impact on human health, such as viruses and bacteria.

[0025] In addition, the control method for the air purification device in the above-mentioned technical solution provided by the present invention may also have the following additional technical features:

[0026] In some technical solutions of the present invention, optionally, the discharge component includes a connection end and a discharge end, the connection end being used to connect to the other of the positive and negative electrodes, and the discharge end being used for discharge.

[0027] In this technical solution, the discharge component is a discharge needle, which includes a connecting end and a emitting end. The connecting end of the discharge needle is electrically connected to the power supply component, and the power supply component supplies power to the discharge needle through the connecting end. After being energized, the discharge needle can release ions, which can attach to pollutants in the electric field area.

[0028] Specifically, the discharge components include discharge needles or discharge brushes.

[0029] Optionally, in some technical solutions of the present invention, the air purification device further includes: a first voltage regulator connected to the dust collection assembly, the first voltage regulator being used to connect to a power source and to adjust the potential of the dust collection assembly to be higher than the ground potential; and a second voltage regulator connected to a connection terminal, the second voltage regulator being used to connect to a power source and to adjust the potential of the discharge component to be lower than the ground potential.

[0030] In this technical solution, the dust collection component and the discharge component can be powered independently, facilitating a separate design. Specifically, the dust collection component is connected to the power supply via a first voltage regulator. Under the voltage regulation of the first voltage regulator, the potential of the dust collection component is higher than the ground potential, thus creating a positive voltage between the dust collection component and the zero electrode. Correspondingly, the discharge component is connected to the power supply via a second voltage regulator. Under the voltage regulation of the second voltage regulator, the potential of the discharge component is lower than the ground potential, thus creating a negative voltage between the discharge component and the zero electrode. The discharge component carrying the negative voltage can release negative ions into the air, thereby making the pollutants in the air negatively charged. After the pollutants carry the negative charge, they move towards the positively charged dust collection component and are eventually captured by the dust collection component, thus removing the pollutants from the air. In some technical solutions of this invention, optionally, the air purification device further includes: a base, on which the dust collection component and the discharge component are disposed.

[0031] Optionally, in some technical solutions of the present invention, the air purification device further includes: a bracket, and the discharge component is connected to the bracket.

[0032] In this technical solution, the bracket is used to position and support the discharge component. After the discharge component is energized, it can release ions into the discharge port it faces.

[0033] In some technical solutions of the present invention, optionally, the discharge component is a discharge needle, the discharge needle includes: a first discharge needle, the emitting end of the first discharge needle is oriented in a first direction, the first direction is parallel to the dust collection surface.

[0034] In this technical solution, the discharge needle includes a first discharge needle located in front of the dust collection surface, with the emitting end of the first discharge needle facing a first direction parallel to the dust collection surface. When the dust collection surface is planar, the first discharge needle is perpendicular to the normal direction of the dust collection surface. After being energized, the first discharge needle releases ions along the first direction. These ions move to the electric field region and attach to the particulate matter, thus charging the particulate matter.

[0035] By setting a first discharge needle parallel to the dust collection surface, the deviation between the trajectory of the released ions and the electric field area generated by the dust collection component can be reduced, thereby increasing the possibility of pollutants in the electric field area being attached by ions, and thus achieving the technical effect of improving the adsorption capacity of air purification equipment for pollutants.

[0036] In some technical solutions of the present invention, optionally, the discharge needle includes: a second discharge needle, wherein the emitting end of the second discharge needle is oriented in a second direction, and the second direction is perpendicular to the dust collection surface.

[0037] In this technical solution, the discharge needle includes a second discharge needle located in front of the dust collection surface. The emitting end of the second discharge needle faces a second direction, which is perpendicular to the dust collection surface. When the dust collection surface is planar, the second discharge needle is parallel to the normal direction of the dust collection surface. After being energized, the second discharge needle releases ions along the second direction. After moving to the electric field region, the ions attach to the particles, thus charging the particles.

[0038] By setting a second discharge needle perpendicular to the dust collection surface, a certain deviation can be created between the trajectory of the released ions and the electric field region generated by the dust collection component. This allows some of the released ions to enter the electric field region and be captured by the dust collection component, while others can move to areas outside the electric field region, sterilizing pollutants outside the electric field region. Thus, while maintaining and enhancing the dust collection component's ability to adsorb pollutants, the sterilization capability of the discharge component is strengthened, enabling the air purification equipment to perform both pollutant collection and sterilization functions. This ultimately achieves the technical effect of broadening the functionality of air purification equipment and improving its practicality and reliability.

[0039] In some technical solutions of the present invention, optionally, the discharge needle includes: a third discharge needle, the emitting end of the third discharge needle is oriented in a third direction, and the angle between the third direction and the dust collection surface is a first angle; the range of the first angle is: greater than or equal to 0° and less than or equal to 90°.

[0040] In this technical solution, the discharge needle includes a third discharge needle, which is located in front of the dust collection surface, and the emitting end of the third discharge needle is oriented in the third direction. The angle between the third direction and the dust collection surface is between 0° and 90°. After being energized, the third discharge needle releases ions along the third direction. After moving to the electric field region, the ions attach to the particles, thereby charging the particles.

[0041] When the dust collection surface is a flat plane or a smooth, outward-curving surface, the resulting electric field region is fan-shaped. By setting a third discharge needle, the trajectory of ions in the electric field region can be extended by constructing a first included angle, thereby increasing the likelihood of ions attaching to pollutants and thus achieving the technical effect of improving the air purification equipment's ability to adsorb pollutants.

[0042] Optionally, in some technical solutions of the present invention, the bracket can be adjusted by rotation to change the first included angle.

[0043] In this technical solution, during operation, the orientation of the third discharge needle can be adjusted by controlling the rotation of the bracket, thereby adjusting the size of the first included angle. The adjustment range of the first included angle is greater than or equal to 0° and less than or equal to 90°.

[0044] By mounting the third discharge needle on a rotatable bracket, its orientation can be adjusted to meet specific purification needs. Specifically, when the pollutant concentration in the air is high, rotating the bracket reduces the first angle, enhancing the adsorption capacity of the third discharge needle on the dust collection component. Conversely, when the pollutant concentration is low, rotating the bracket increases the first angle, improving the sterilization effect of the third discharge needle on the airborne pollutants. This allows the enhanced and sterilization functions of the third discharge needle to be adjusted according to actual requirements. Alternatively, controlling the bracket's oscillation can expand the overlap between the ion release area and the electric field area, increasing the likelihood of pollutants in the electric field area being attached by ions. This enhances the intelligence and practicality of the air purification equipment.

[0045] Optionally, in some technical solutions of the present invention, the air purification device further includes: a driving component connected to the bracket for driving the bracket to rotate.

[0046] In this technical solution, the discharge component also includes a driving component, and the driving end of the driving component is connected to the bracket. When energized, the driving component can rotate the bracket to adjust the size of the first included angle. By setting up the driving component, the bracket can be rotated to automatically adjust the orientation of the third discharge needle, eliminating the need for manual adjustment of the bracket by the user. This achieves the technical effect of improving the automation level of the air purification equipment.

[0047] Specifically, the driving component is a motor, and the output shaft of the motor is connected to the rotating shaft of the third bracket. The motor drives the bracket and the third discharge needle to rotate synchronously through the rotating shaft.

[0048] In some technical solutions of the present invention, optionally, the number of discharge needles is multiple; multiple discharge needles are arranged side by side on the support.

[0049] In this technical solution, multiple discharge needles are arranged side-by-side on the support. By arranging multiple discharge needles side-by-side on the support, the coverage area of ​​the ions released by the discharge needles can be expanded, thereby increasing the overlap between the ion coverage area and the electric field area. This increases the number of ions released into the electric field area, reduces the difficulty for pollutants to adhere to the electric field area, and achieves the technical effect of improving the adsorption capacity of the dust collection component for pollutants.

[0050] Optionally, in some technical solutions of the present invention, the air purification device further includes: a base, a dust collection assembly, and a discharge component disposed on the base.

[0051] In this technical solution, the air purification equipment also includes a base, on which a dust collection component and a discharge component are mounted. The base is used to position and support the dust collection component and the discharge component, while locking the relative positions between the dust collection component and the discharge component.

[0052] Meanwhile, the base has a large contact surface and a low center of gravity, which can reduce the probability of the dust collection components and discharge components tilting or tipping over.

[0053] Specifically, the bracket is set in a cavity inside the base and connected to the base.

[0054] Specifically, the third discharge needle is mounted on the bracket, and the bracket is rotatably connected to the base.

[0055] Specifically, the drive component is fixed to the base.

[0056] In some technical solutions of the present invention, optionally, the base includes a cavity and a discharge port; the discharge component is disposed in the cavity, and the discharge port is disposed opposite to the discharge component.

[0057] In this technical solution, a discharge port is also provided on the base, and the discharge port is connected to the cavity inside the base. Based on this, the discharge component is set inside the cavity, with the discharge end of the discharge component facing the discharge port. After the discharge component is energized, it can discharge to the outside of the base through the discharge port.

[0058] In some technical solutions of the present invention, optionally, the discharge component is connected to the inner wall of the cavity.

[0059] In this technical solution, the discharge component is fixed on the inner wall of the cavity. Specifically, the discharge component can be inserted into a slot on the inner wall of the cavity, or the discharge component can be fixed on the inner wall of the cavity by screws or other connectors to ensure that the discharge component can be accurately fixed in the predetermined working position.

[0060] Optionally, in some technical solutions of the present invention, the air purification device further includes: a power supply component disposed on the base, the power supply component including a positive electrode and a negative electrode, the positive electrode being connected to one of the dust collection component and the discharge component, and the negative electrode being connected to the other of the dust collection component and the discharge component.

[0061] In this technical solution, the air purification equipment also includes a power supply component. One of the positive and negative terminals of the power supply component is connected to the dust collection assembly, and the other is connected to a discharge component, so that the ions accumulated inside the dust collection assembly and the ions released by the discharge component have opposite polarities. The ions released by the discharge component attach to pollutants in the electric field area, causing the pollutants to carry a charge opposite to that of the dust collection assembly. This increases the adsorption force of the dust collection assembly on the existing Coulomb force, causing the pollutants to move faster towards the dust collection surface, thereby improving the adsorption capacity of the dust collection assembly. This compensates for the shortcomings of electric field adsorption and solves the technical problems of insufficient Coulomb force on pollutants, inadequate pollutant capture capacity, and poor purification effect in related technologies. Ultimately, this optimizes the structure of the air purification equipment, improves its purification capacity, and enhances the user experience.

[0062] In some technical solutions of the present invention, optionally, the dust collection assembly includes: a protective plate, the number of protective plates being N, where N is an integer greater than 1, the N protective plates being stacked, and adjacent protective plates being spaced apart; a conductive component, disposed between adjacent protective plates, the conductive component being used to generate an electric field when energized, and the surface of the protective plate facing away from the conductive component being the dust collection surface.

[0063] In this technical solution, the structure of the dust collection assembly is refined. Specifically, the dust collection assembly includes protective plates and conductive components. Specifically, there are multiple protective plates, which are stacked along the thickness direction of the base, with adjacent protective plates spaced apart to form gaps between them. The conductive components are disposed in the gaps between adjacent protective plates, and can generate an electric field when energized. On the multiple protective plates, the surface facing away from the conductive components is the dust collection surface. For example, when there are two protective plates, the outer surfaces of the two plates form two dust collection surfaces. When there are three protective plates, the two middle protective plates face the conductive components and do not form dust collection surfaces, while the outer surfaces of the two outer protective plates form two dust collection surfaces. That is, increasing the number of protective plates does not increase the number of dust collection surfaces.

[0064] Specifically, the air purification equipment also includes a power supply component, which is housed in the base. The power supply component includes a positive electrode and a negative electrode, and a conductive component is connected to the positive electrode to supply a positive DC high voltage to the conductive component. After the positive DC high voltage is applied to the conductive component, a large number of negative ions can be stored within it, thus forming an electric field. When pollutants move into the electric field area, they become polarized under the influence of the electric field and are adsorbed onto the dust collection surface. The closer the pollutants are to the dust collection surface, the stronger the adsorption force; therefore, there is a process of accelerated movement of pollutants towards the dust collection surface.

[0065] Based on this, a first conductive layer is applied to the surface of the protective plate facing the conductive components. This first conductive layer enhances the electric field, thereby strengthening the dust collection assembly's ability to adsorb pollutants. Specifically, the first conductive layer is a barium carbonate coating.

[0066] Specifically, the protective plate is made of silicon dioxide tempered glass. Silicon dioxide tempered glass has the advantages of high strength, strong corrosion resistance, and insulation, providing long-term and effective protection for internal conductive components, thereby improving the reliability of the dust collection assembly and reducing its failure rate. At the same time, its insulation properties prevent leakage problems in the dust collection assembly, thus improving its safety.

[0067] Specifically, the conductive component includes a conductive wire and a second conductive layer. The conductive wire is electrically connected to the power supply component, and the second conductive layer is wrapped around the conductive wire. By setting the second conductive layer, the conductivity of the conductive component can be further improved, thereby increasing the strength of the electric field and enhancing the dust collection component's ability to adsorb pollutants.

[0068] Specifically, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0069] Specifically, conductive foam is also provided between two adjacent protective plates. The conductive foam, together with conductive wires and a second conductive layer, fills the gap between the two adjacent protective plates.

[0070] In some technical solutions of the present invention, the base may optionally include a cavity, a first airflow port and a second airflow port, the first airflow port being connected to the second airflow port through the cavity, and may also include an ion wind assembly disposed within the cavity.

[0071] In this technical solution, a first airflow port and a second airflow port are also provided on the base. The first airflow port is connected to the second airflow port through the cavity, that is, the first airflow port, the cavity and the second airflow port are combined to form an airflow passage.

[0072] Building upon this foundation, the air purifier also includes an ionization fan assembly. This assembly is housed within the cavity. When powered on, it generates directionally moving ions. These ions, in their directional movement, drive the flow of nearby air, creating a corresponding directional airflow. This airflow accelerates airflow around the purifier, thus enhancing air purification capabilities in conjunction with the dust collection and discharge components. Furthermore, the directional ionization kills pollutants in the airflow, reducing the concentration of toxic substances and protecting user health.

[0073] In some technical solutions of the present invention, optionally, the ion wind assembly includes: a frame including a wind duct, the end of which is opposite to the first airflow port; an ion emitting component disposed within the wind duct; and an ion receiving component disposed within the wind duct and opposite to the ion emitting component.

[0074] In this technical solution, the structure of the ion wind assembly is refined. The ion wind assembly includes a frame, an ion generating component, and an ion receiving component. The frame is disposed within a cavity and connected to a base. A through-flow air duct is provided within the frame, with the outlet end of the air duct facing the first airflow port. The ion emitting component and the ion receiving component are disposed within the frame, which provides support and protection for them. Specifically, the ion receiving component is positioned near the outlet end of the air duct, and the ion receiving component is positioned near the inlet end of the air duct.

[0075] One of the ion emitting component and the ion receiving component is connected to the positive terminal of the power supply component, and the other is connected to the negative terminal of the power supply component. After being powered on, the ion emitting component releases ions, which are captured by the ion receiving component, thereby forming a directional flow of ions and a directional flow of airflow. The airflow exits the base through the outlet end of the air duct and the first airflow port to form a circulation with the second airflow port.

[0076] In some technical solutions of the present invention, the air purification device may optionally include: a controller electrically connected to the dust collection component and the discharge component; and a sensor connected to the controller for detecting the concentration of pollutants in the air.

[0077] In this technical solution, the air purification equipment also includes a controller and sensors. Both the controller and sensors are mounted on a base. The controller is electrically connected to the dust collection assembly and the discharge component, and the sensors are connected to the controller. During operation, the controller obtains the concentration value of pollutants in the air from the sensors, and then controls the start / stop and power of the dust collection assembly based on the concentration value.

[0078] Specifically, when the air quality is poor, the dust collection components should be turned on or their power increased in a timely manner, and when the air quality is good, the dust collection components should be turned off or their power reduced in a timely manner.

[0079] When air quality is poor, the first angle can be reduced by controlling the drive component, or the drive component can be controlled to cause the third discharge needle to swing frequently. When air quality is good, the first angle can be increased by controlling the drive component, or the discharge component can be controlled to shut down.

[0080] Therefore, by setting up controllers and sensors, the working status of air purification equipment can be adjusted in a targeted manner according to air quality, ensuring that the working status of dust collection components and discharge components can match the actual environment, thereby achieving the technical effect of improving the intelligence level of air purification equipment.

[0081] A second aspect of the present invention provides a control method for an air purification device. The air purification device includes a base, a dust collection assembly, and a discharge component. The dust collection assembly is disposed on the base, and the discharge component is rotatably connected to the base. The control method for the air purification device includes: acquiring the concentration value of pollutants in the air; and controlling the rotation of the discharge component according to the concentration value.

[0082] In this technical solution, the air purification equipment is used to treat pollutants in the air, thereby reducing the pollutant content in the air. The air purification equipment includes a base and a dust collection assembly; the base is used to position, support, and protect the dust collection assembly.

[0083] The dust collection component includes a dust collection surface, which is housed within a base that avoids the dust collection surface, allowing it to be exposed to the air. When energized, the dust collection component accumulates ions, generating an electric field. This electric field forms a region in front of the dust collection surface. Pollutants within this region are polarized and move towards the dust collection surface under the influence of Coulomb forces until they are adsorbed onto the surface. This adsorption reduces the concentration of pollutants within the electric field region. Due to the concentration difference, pollutants outside the electric field region migrate to the lower concentration region, thereby reducing the overall concentration of pollutants in the environment and achieving air purification.

[0084] In addition, the air purification device also includes a discharge component. The discharge end of the discharge component releases ions into the area facing the dust collection surface. These released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component. One of the positive and negative electrodes of the power supply component is connected to the dust collection assembly, and the other is connected to the discharge component, so that the ions accumulated inside the dust collection assembly and the ions released by the discharge component have opposite polarities.

[0085] The ions released by the discharge component attach to the pollutants in the electric field area, so that the pollutants have an opposite charge to the dust collection component. This increases the adsorption force of the dust collection component on the pollutants on the basis of the original Coulomb force, causing the pollutants to move faster toward the dust collection surface, thereby improving the adsorption capacity of the dust collection component and making up for the shortcomings of electric field adsorption.

[0086] The discharge component is rotatably connected to the base, and its orientation can be adjusted by controlling its rotation, thereby adjusting the direction of ion transmission. Specifically, the discharge component is rotatably connected to the base via a bracket, and the orientation of the third discharge needle on the bracket can be adjusted by controlling the rotation of the bracket.

[0087] Based on this, the control method for the air purification equipment is as follows: After the air purification equipment is turned on based on the purification command, the concentration value of pollutants in the air is obtained through sensors. After obtaining the concentration value, the discharge component is controlled to rotate according to the concentration value, so that the discharge component faces the target direction, or the discharge component oscillates at the target frequency.

[0088] By defining the aforementioned control steps, the discharge component can rotate or oscillate according to the density of pollutants, ensuring that its operating state meets the cleaning requirements corresponding to the current pollutant concentration, thereby enhancing the air purification equipment's ability to capture pollutants. This solves the technical problems of insufficient Coulomb force on pollutants, inadequate pollutant capture capacity, and poor purification effect existing in related technologies. Ultimately, it optimizes the control process of air purification equipment, improves its purification capacity, and enhances the user experience.

[0089] In some technical solutions of the present invention, optionally, the step of controlling the rotation of the discharge component according to the concentration value includes: determining the target direction according to the concentration value; controlling the rotation of the discharge component so that the discharge component faces the target direction.

[0090] In this technical solution, the step of controlling the rotation of the discharge component based on the concentration value is refined. Specifically, after obtaining the concentration value, the corresponding target direction is determined based on the concentration value. After determining the target direction, the rotation of the discharge component is controlled so that the third discharge needle on the discharge component faces the target direction.

[0091] By defining the aforementioned control steps, the dust collection component can adjust its orientation based on the pollutant concentration, thereby automatically adjusting the overlap between the ion-covered area and the electric field area, as well as the incident direction of the ions. This adjusts the difficulty of ion capture by the dust collection component, automatically distributing the enhancement effect of the discharge component on the dust collection component and the sterilization effect on air pollutants. Ultimately, this improves the automation and intelligence of the air purification equipment, enhancing its air purification capabilities.

[0092] In some technical solutions of the present invention, optionally, the dust collection component includes a dust collection surface, which can generate an electric field when energized, and the dust collection surface is used to collect pollutants in the air through the electric field; the angle between the target direction and the dust collection surface is a first angle; the first angle is negatively correlated with the concentration value.

[0093] In this technical solution, the discharge component includes a support and a third discharge needle. The emitting end of the third discharge needle is oriented in a third direction, and the angle between the third direction and the dust collection surface is a first angle; the first angle is greater than or equal to 0° and less than or equal to 90°. The third discharge needle is rotatably connected to the base via the support; the support can adjust the first angle by rotation. By mounting the third discharge needle on a rotatable support, the orientation of the third discharge needle can be adjusted according to actual purification needs.

[0094] Specifically, when the pollutant concentration in the air is high, the first angle is reduced by rotating the support to enhance the adsorption capacity of the third discharge needle on the dust collection component. Conversely, when the pollutant concentration is low, the first angle is increased by rotating the support to enhance the sterilization effect of the third discharge needle on the air pollutants. This allows the enhancement and sterilization functions of the third discharge needle to be adjusted according to actual needs. Alternatively, the overlap between the ion release area and the electric field area can be expanded by controlling the swing of the support, thereby increasing the likelihood of pollutants in the electric field area being attached by ions. This achieves the technical effect of improving the intelligence and practicality of the air purification equipment.

[0095] In some technical solutions of the present invention, optionally, the step of controlling the rotation of the discharge component according to the concentration value includes: controlling the discharge component to swing based on the concentration value being greater than or equal to a first threshold; and controlling the discharge component to stop swinging based on the concentration value being less than the first threshold.

[0096] This technical solution refines the steps for controlling the rotation of the discharge component based on the concentration value. Specifically, after obtaining the concentration value, it is compared with a first threshold. If the concentration value is greater than or equal to the first threshold, the discharge component is controlled to oscillate. During the oscillation, the angle between the third discharge needle on the discharge component and the dust collection surface ranges from 0° to 90°. This oscillation increases the overlap between the ion coverage area and the electric field area, reducing the difficulty for ions to adhere to pollutants in the discharge area. Correspondingly, when the concentration value is less than the first threshold, the discharge component stops oscillating to avoid the oscillating discharge needle affecting the sterilization effect of the discharge component on pollutants and to reduce unnecessary energy consumption. This achieves the technical effect of improving the intelligence level and practicality of the air purification equipment.

[0097] In some technical solutions of the present invention, optionally, the step of controlling the oscillation of the discharge component includes: determining a target frequency based on the concentration value; and controlling the discharge component to oscillate according to the target frequency.

[0098] This technical solution refines the steps for controlling the oscillation of the discharge component. Specifically, when the concentration value exceeds a first threshold, a target frequency is first determined based on the concentration value, and then the discharge component is controlled to oscillate according to the target frequency. This ensures that the oscillation frequency of the discharge component matches the current air quality, ensuring that the air purification equipment can meet the air purification requirements. This, in turn, enhances the intelligence and practicality of the air purification equipment.

[0099] In some technical solutions of the present invention, optionally, the target frequency is positively correlated with the concentration value.

[0100] In this technical solution, the target frequency is positively correlated with the concentration value. That is, the higher the concentration, the higher the oscillation frequency of the discharge component; conversely, the lower the concentration, the lower the oscillation frequency. At higher concentrations, controlling the high-frequency oscillation of the discharge component allows ions to adhere to pollutants entering the electric field region in a timely manner, accelerating the rate at which pollutants are captured by the dust collection surface. At lower concentrations, controlling the low-frequency oscillation of the discharge component reduces energy consumption while still meeting the pollutant adhesion requirements. This ultimately enhances the intelligence and practicality of the air purification equipment.

[0101] Optionally, in some technical solutions of the present invention, the control method of the air purification device further includes: controlling the dust collection component and the discharge component to turn on based on the concentration value being greater than or equal to a second threshold; and controlling the dust collection component and the discharge component to turn off based on the concentration value being less than the second threshold.

[0102] In this technical solution, after obtaining the concentration value, the relationship between the concentration value and a second threshold is compared. If the concentration value is greater than or equal to the second threshold, it indicates a high level of pollutants in the air, requiring purification. The dust collection component and discharge component are then activated to initiate the purification mode of the air purifier. Conversely, if the concentration value is less than the second threshold, it indicates a low level of pollutants in the air, meeting the user's air cleanliness requirements. The dust collection component and discharge component are then deactivated to exit the purification mode of the air purifier. The second threshold is less than or equal to the first threshold; specifically, the second threshold can be selected as 75 μg / m².

[0103] By limiting the above control steps, the automatic start and stop of the air purification mode is achieved, thereby maintaining the concentration of pollutants in the current environment below the second threshold. This results in improved automation and intelligence of the air purification equipment, enhanced purification capacity, and reduced energy consumption.

[0104] A third aspect of the present invention provides a control device for an air purification device. The air purification device includes a base, a dust collection assembly, and a discharge component. The dust collection assembly is disposed on the base, and the discharge component is rotatably connected to the base. The control method of the air purification device includes: an acquisition module for acquiring the concentration value of pollutants in the air; and a control module for controlling the rotation of the discharge component according to the concentration value.

[0105] In this technical solution, the air purification equipment is used to treat pollutants in the air, thereby reducing the pollutant content in the air. The air purification equipment includes a base and a dust collection assembly; the base is used to position, support, and protect the dust collection assembly.

[0106] The dust collection component includes a dust collection surface, which is housed within a base that avoids the dust collection surface, allowing it to be exposed to the air. When energized, the dust collection component accumulates ions, generating an electric field. This electric field forms a region in front of the dust collection surface. Pollutants within this region are polarized and move towards the dust collection surface under the influence of Coulomb forces until they are adsorbed onto the surface. This adsorption reduces the concentration of pollutants within the electric field region. Due to the concentration difference, pollutants outside the electric field region migrate to the lower concentration region, thereby reducing the overall concentration of pollutants in the environment and achieving air purification.

[0107] In addition, the air purification device also includes a discharge component. The discharge end of the discharge component releases ions into the area facing the dust collection surface. These released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component. One of the positive and negative electrodes of the power supply component is connected to the dust collection assembly, and the other is connected to the discharge component, so that the ions accumulated inside the dust collection assembly and the ions released by the discharge component have opposite polarities.

[0108] The ions released by the discharge component attach to the pollutants in the electric field area, so that the pollutants have an opposite charge to the dust collection component. This increases the adsorption force of the dust collection component on the pollutants on the basis of the original Coulomb force, causing the pollutants to move faster toward the dust collection surface, thereby improving the adsorption capacity of the dust collection component and making up for the shortcomings of electric field adsorption.

[0109] The discharge component is rotatably connected to the base, and its orientation can be adjusted by controlling its rotation, thereby adjusting the direction of ion transmission. Specifically, the discharge component is rotatably connected to the base via a bracket, and the orientation of the third discharge needle on the bracket can be adjusted by controlling the rotation of the bracket.

[0110] Based on this, the control device of the air purification equipment includes an acquisition module and a control module. After the air purification equipment is turned on based on the purification command, the acquisition module acquires the concentration value of pollutants in the air through sensors. After acquiring the concentration value, the control module controls the discharge component to rotate, so that the discharge component faces the target direction, or to make the discharge component oscillate at the target frequency.

[0111] By limiting the aforementioned control device, the discharge component can rotate or oscillate according to the density of pollutants, ensuring that the working state of the discharge component meets the cleaning requirements corresponding to the current concentration of pollutants, thereby improving the air purification equipment's ability to capture pollutants. This solves the technical problems of insufficient Coulomb force on pollutants, inadequate pollutant capture capacity, and poor purification effect existing in related technologies. Ultimately, it optimizes the control process of air purification equipment, enhances its purification capacity, and improves the user experience.

[0112] A fourth aspect of the present invention provides a control device for an air purification device, the control device comprising: a memory storing a program or instructions; and a processor executing the program or instructions stored in the memory to implement the steps of the control method for the air purification device as described in any of the above technical solutions.

[0113] This technical solution defines a control device for an air purification device. The processor in this control device executes the programs and instructions stored in its memory, thereby implementing the steps of the control method for the air purification device described in any of the aforementioned technical solutions. Therefore, this control device for the air purification device possesses the advantages of the control methods for the air purification devices described in any of the aforementioned technical solutions, and can achieve the technical effects achievable by the control methods for the air purification devices described in any of the aforementioned technical solutions.

[0114] A fifth aspect of the present invention provides a readable storage medium storing a program or instructions that, when executed by a processor, implement the steps of the control method for an air purification device as described in any of the above technical solutions.

[0115] This technical solution defines a readable storage medium.

[0116] A sixth aspect of the present invention provides an air purification device, the air purification device comprising: a control device for an air purification device as described in any of the above technical solutions, or a readable storage medium as described in the above technical solutions.

[0117] This technical solution defines an air purification device that possesses the advantages of the control device in any of the aforementioned technical solutions, or the advantages of the readable storage medium in the aforementioned technical solutions.

To avoid repetition, further details are omitted here.

Detailed Implementation

[0149] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0150] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0151] The following reference Figures 1 to 27 An air purification device, control method, apparatus, and storage medium thereof are described according to some embodiments of the present invention.

[0152] like Figure 1 , Figure 2 and Figure 3As shown, one embodiment of the present invention provides an air purification device 100, which includes: a dust collection assembly 120, the dust collection assembly 120 including a dust collection surface 122, the dust collection assembly 120 being able to generate an electric field when energized, the dust collection surface 122 being used to collect pollutants 200 in the air through the electric field; and a discharge component 144, the discharge component 144 being used to discharge to the area facing the dust collection surface 122; wherein, the dust collection assembly 120 is used to connect to one of the positive and negative electrodes, and the discharge component 144 is used to connect to the other of the positive and negative electrodes.

[0153] This application defines an air purification device 100 for treating air pollutants 200 to reduce their concentration. The air purification device 100 includes a dust collection assembly 120.

[0154] The dust collection component 120 includes a dust collection surface 122, which can be exposed to the air. When energized, the dust collection component 120 accumulates ions inside, generating an electric field. This electric field forms an electric field region in front of the dust collection surface 122. Pollutants 200 within this electric field region are polarized and move towards the dust collection surface 122 under the influence of Coulomb force until they are adsorbed onto the surface. This adsorption reduces the concentration of pollutants 200 within the electric field region. Due to the concentration difference, pollutants 200 outside the electric field region migrate to the lower concentration electric field region, thereby reducing the overall concentration of pollutants 200 in the environment and achieving air purification.

[0155] Based on this, the air purification device 100 also includes a discharge component 144. The discharge end of the discharge component 144 releases ions into the area facing the dust collection surface 122. The released ions can act on the pollutants 200 in the electric field area. Specifically, the air purification device 100 also includes a power supply component. One of the positive and negative electrodes of the power supply component is connected to the dust collection assembly 120, and the other is connected to the discharge component 144, so that the ions accumulated inside the dust collection assembly 120 and the ions released by the discharge component 144 have opposite polarities.

[0156] The ions released by the discharge component 144 attach to the pollutants 200 in the electric field region, causing the pollutants 200 to carry an opposite charge to the dust collection component 120. This increases the adsorption force of the dust collection component 120 on the pollutants 200, based on the original Coulomb force, causing the pollutants 200 to move faster towards the dust collection surface 122. This enhances the adsorption capacity of the dust collection component 120, compensating for the shortcomings of electric field adsorption and solving the technical problems of insufficient Coulomb force on pollutants 200, insufficient pollutant capture capacity, and poor purification effect in related technologies. This optimizes the structure of the air purifier 100, improves its purification capacity, and enhances the user experience. Simultaneously, the ions released by the discharge component 144 also have a bactericidal effect, reducing the content of toxic substances in the air and protecting user health.

[0157] Based on this, the dust collection component 120 proposed in this application collects pollutants 200 through an electric field. The collected pollutants 200 adhere to the dust collection surface 122. After use, the pollutants 200 can be removed by cleaning or wiping the dust collection surface 122, eliminating the need for frequent filter replacement and reducing the operating cost of the air purification equipment 100. At the same time, the dust collection component 120 generates relatively low noise when powered on, which can further improve the user experience.

[0158] Specifically, the dust collection component 120 proposed in this application can actively adsorb pollutants 200 in the air by means of its own generated electric field, without relying on circulating airflow to achieve air purification function, thereby saving the space for arranging air duct 1522 and fan, and providing convenient conditions for miniaturization and lightweight design of air purification equipment 100.

[0159] Specifically, such as Figure 24 and Figure 25 As shown, the dust collection component 120 and the discharge component 144 can be separate structures, with independent power supplies for both. Their positions can be freely adjusted according to the specific requirements of the scenario. During use, the dust collection component 120 is first positioned, and then the discharge component 144 is placed within the electric field area generated by the dust collection component 120 to ensure that the discharge component 144 can effectively cooperate with the dust collection component 120 to adsorb pollutants 200 from the air.

[0160] Specifically, such as Figure 2 , Figure 4 and Figure 5As shown, the dust collection assembly 120 and the discharge component 144 can be an integrated structure, for example, the dust collection assembly 120 and the discharge component 144 can be directly connected, or the dust collection assembly 120 and the discharge component 144 can be fixed together on the same base. In this integrated structure, the relative position of the dust collection assembly 120 and the discharge component 144 is locked, which can ensure that the discharge component 144 can discharge into the electric field region generated by the dust collection assembly 120.

[0161] The pollutants 200 mentioned in this application are mainly solid particulate pollutants 200, which include dust, smoke, particulate matter, bacteria, viruses, etc. They vary in diameter and can generally be classified into the following categories according to their diameter:

[0162] Visible particulate matter: Particulate matter with a diameter of 10 micrometers or less can be seen, such as dust, pollen, and human skin flakes.

[0163] Fine particulate matter: Particulate matter with a diameter of 2.5 micrometers or less, which cannot be seen with the naked eye, but has a significant impact on human health, such as automobile exhaust and factory exhaust.

[0164] Ultrafine particles: Particles with a diameter of 0.1 micrometers or less, which cannot be seen with the naked eye, but can penetrate deep into the human respiratory tract and have a greater impact on human health, such as viruses and bacteria.

[0165] like Figure 4 and Figure 5 As shown, in some technical solutions of the present invention, optionally, the discharge component 144 includes a connection end and a transmitter end, the connection end being used to connect to the other of the positive and negative electrodes, and the transmitter end being used for discharge.

[0166] In this technical solution, the discharge component 144 includes a connection end and a transmitter end. The connection end is electrically connected to the power supply component, and the power supply component supplies power to the discharge component 144 through the connection end. After being powered on, the discharge component 144 can release ions, which can attach to the pollutants 200 in the electric field area.

[0167] Specifically, the discharge component 144 includes a discharge needle or a discharge brush.

[0168] like Figure 25 , Figure 26 and Figure 27As shown, in some technical solutions of the present invention, optionally, the air purification device 100 further includes: a first voltage regulator 170, connected to the dust collection assembly 120, the first voltage regulator 170 being used to connect to a power source, and the first voltage regulator 170 being used to adjust the potential of the dust collection assembly 120 to be higher than the ground potential; and a second voltage regulator 180, connected to a connection terminal, the second voltage regulator 180 being used to connect to a power source, and the second voltage regulator 180 being used to adjust the potential of the discharge component 144 to be lower than the ground potential.

[0169] Figure 25 The middle arrow e indicates the negative ions released into the air by the discharge component 144.

[0170] In this technical solution, the dust collection component 120 and the discharge component 144 can be powered independently, facilitating a separate design for the dust collection component 120 and the discharge component 144. Specifically, the dust collection component 120 is connected to a power source via a first voltage regulator 170. Under the voltage regulation of the first voltage regulator 170, the potential of the dust collection component 120 is higher than the ground potential, thereby creating a positive voltage between the dust collection component 120 and the zero electrode. Correspondingly, the discharge component 144 is connected to a power source via a second voltage regulator 180. Under the voltage regulation of the second voltage regulator 180, the potential of the discharge component 144 is lower than the ground potential, thereby creating a negative voltage between the discharge component 144 and the zero electrode. The discharge component 144, carrying a negative voltage, can release negative ions into the air, thus making the pollutants 200 in the air negatively charged. After the pollutants 200 become negatively charged, they move towards the positively charged dust collection component 120 and are eventually captured by the dust collection component 120, thereby removing the pollutants 200 from the air.

[0171] like Figure 7 As shown, in some embodiments of the present invention, optionally, the discharge component 144 is a discharge needle, the discharge needle includes: a first discharge needle 1442, the emitting end of the first discharge needle 1442 is oriented in a first direction, the first direction is parallel to the dust collection surface 122.

[0172] Figure 7 , Figure 8 and Figure 9 In the image, arrow a indicates the orientation of the dust collection surface.

[0173] In this embodiment, the discharge needle includes a first discharge needle 1442, which is located in front of the dust collection surface 122. The emitting end of the first discharge needle 1442 is oriented in a first direction, which is parallel to the dust collection surface 122. When the dust collection surface 122 is planar, the first discharge needle 1442 is perpendicular to the normal direction of the dust collection surface 122. After being energized, the first discharge needle 1442 releases ions along the first direction. After moving to the electric field region, the ions attach to the particles, thereby charging the particles.

[0174] By setting a first discharge needle 1442 parallel to the dust collection surface 122, the deviation between the trajectory of the released ions and the electric field area generated by the dust collection component 120 can be reduced, thereby increasing the possibility of pollutants 200 in the electric field area being attached by ions, and thus achieving the technical effect of improving the adsorption capacity of the air purification device 100 for pollutants 200.

[0175] like Figure 8 As shown, in some embodiments of the present invention, optionally, the discharge needle includes: a second discharge needle 1444, the emitting end of the second discharge needle 1444 is oriented in a second direction, the second direction being perpendicular to the dust collection surface 122.

[0176] In this embodiment, the discharge needle includes a second discharge needle 1444, which is located in front of the dust collection surface 122. The emitting end of the second discharge needle 1444 faces a second direction, which is perpendicular to the dust collection surface 122. When the dust collection surface 122 is planar, the second discharge needle 1444 is parallel to the normal direction of the dust collection surface 122. After being energized, the second discharge needle 1444 releases ions along the second direction. After moving to the electric field region, the ions attach to the particles, thereby charging the particles.

[0177] By setting a second discharge needle 1444 perpendicular to the dust collection surface 122, a certain deviation can be made between the trajectory of the released ions and the electric field region generated by the dust collection component 120. This allows some of the released ions to enter the electric field region and be captured by the dust collection component 120, while other ions can move to areas outside the electric field region and sterilize the pollutants 200 outside the electric field region. Thus, while maintaining and improving the adsorption capacity of the dust collection component 120 for pollutants 200, the sterilization capacity of the discharge component 144 for airborne pollutants 200 is enhanced, enabling the air purification device 100 to perform both pollutant collection and sterilization functions. This achieves the technical effect of broadening the functionality of the air purification device 100 and improving its practicality and reliability.

[0178] like Figure 9 As shown, in some embodiments of the present invention, optionally, the discharge needle includes: a third discharge needle 1446, the emitting end of the third discharge needle 1446 is oriented in a third direction, and the angle between the third direction and the dust collection surface 122 is a first angle; the range of the first angle is: greater than or equal to 0° and less than or equal to 90°.

[0179] In this embodiment, the discharge needle includes a third discharge needle 1446, which is located in front of the dust collection surface 122. The emitting end of the third discharge needle 1446 is oriented in a third direction, and the angle between the third direction and the dust collection surface 122 is between 0° and 90°. After being energized, the third discharge needle 1446 releases ions along the third direction. After moving to the electric field region, the ions attach to the particles, thereby charging the particles.

[0180] When the dust collection surface 122 is a flat surface or an outwardly curved surface, the electric field region formed is fan-shaped. By setting the third discharge needle 1446, the trajectory of the ions in the electric field region can be extended by constructing the first included angle, thereby increasing the possibility of the ions attaching to the pollutants 200, and thus achieving the technical effect of improving the adsorption capacity of the air purification equipment 100 for the pollutants 200.

[0181] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of the present invention, optionally, the third discharge needle 1446 is rotatably connected to the base 110 via a bracket 142; the bracket 142 can adjust the first included angle by rotation.

[0182] In this embodiment, the third discharge needle 1446 is mounted on the bracket 142, and the bracket 142 is rotatably connected to the base 110. During operation, the orientation of the third discharge needle 1446 can be adjusted by controlling the rotation of the bracket 142, thereby adjusting the size of the first included angle, wherein the adjustment range of the first included angle is greater than or equal to 0° and less than or equal to 90°.

[0183] By mounting the third discharge needle 1446 on the rotatable bracket 142, the orientation of the third discharge needle 1446 can be adjusted according to actual purification needs. Specifically, when the concentration of pollutants 200 in the air is high, rotating the bracket 142 reduces the first angle to enhance the adsorption capacity of the third discharge needle 1446 on the dust collection component 120. Conversely, when the concentration of pollutants 200 in the air is low, rotating the bracket 142 increases the first angle to enhance the sterilization effect of the third discharge needle 1446 on the pollutants 200, thus allowing the enhancement and sterilization functions of the third discharge needle 1446 to be adjusted according to actual needs. Alternatively, the overlap between the ion release area and the electric field area can be expanded by controlling the swing of the bracket 142, thereby increasing the likelihood of pollutants 200 in the electric field area being attached by ions. This achieves the technical effect of improving the intelligence and practicality of the air purification equipment 100.

[0184] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the air purification device 100 may optionally include a driving component 146 connected to the bracket 142 for driving the bracket 142 to rotate.

[0185] In this embodiment, the discharge component 144 further includes a driving component 146, which is fixed to the base 110. The driving end of the driving component 146 is connected to the bracket 142. When the driving component 146 is energized, it can drive the bracket 142 to rotate, thereby adjusting the size of the first included angle. By setting the driving component 146, the bracket 142 can be rotated by the driving component 146 to automatically adjust the orientation of the third discharge needle 1446, eliminating the need for the user to manually adjust the bracket 142. This achieves the technical effect of improving the automation level of the air purification equipment 100.

[0186] Specifically, the driving component 146 is a motor, and the output shaft of the motor is connected to the rotating shaft of the third bracket 142. The motor drives the bracket 142 and the third discharge needle 1446 to rotate synchronously through the rotating shaft.

[0187] like Figure 1 As shown, in some embodiments of the present invention, optionally, the number of discharge needles is multiple; multiple discharge needles are arranged side by side on the bracket 142.

[0188] In this embodiment, a plurality of discharge needles are disposed on the support 142, and the plurality of discharge needles are arranged side by side on the support 142. By arranging a plurality of discharge needles side by side on the support 142, the coverage range of the ions released by the discharge needles can be expanded, thereby increasing the overlap between the ion coverage area and the electric field area, thereby increasing the number of ions released into the electric field area, reducing the difficulty of the pollutants 200 being attached to the electric field area by ions, and achieving the technical effect of improving the adsorption capacity of the dust collection component 120 for the pollutants 200.

[0189] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the air purification device 100 may optionally include: a base 110, a dust collection assembly 120 and a discharge component 144 disposed on the base 110.

[0190] In this technical solution, the air purification device 100 also includes a base 110, on which the dust collection assembly 120 and the discharge component 144 are mounted. The base 110 is used to provide positioning and support for the dust collection assembly 120 and the discharge component 144, and to lock the relative position between the dust collection assembly 120 and the discharge component 144.

[0191] Meanwhile, the base 110 has a large contact surface and a low center of gravity, which can reduce the probability of the dust collection assembly 120 and the discharge component 144 tilting or tipping over.

[0192] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, optionally, the base 110 includes a cavity 117 and a discharge port 116, and the air purification device 100 further includes: a bracket 142 disposed in the cavity 117; a discharge component 144 disposed in the bracket 142, and the discharge port 116 and the discharge component 144 are disposed opposite to each other.

[0193] In this embodiment, a discharge port 116 is also provided on the base 110, and the discharge port 116 is connected to the cavity 117 inside the base 110. Furthermore, the air purification device 100 also includes a discharge component 144, the discharge end of which faces the discharge port 116. When energized, the discharge component 144 can discharge to the outside of the base 110 through the discharge port 116. A bracket 142 is disposed in the cavity 117 inside the base 110 and connected to the base 110. The bracket 142 is used to position and support the discharge component 144. When energized, the discharge component 144 can release ions to the discharge port 116 it faces.

[0194] In some technical solutions of the present invention, optionally, the discharge component 144 is connected to the inner wall of the cavity 117.

[0195] In this technical solution, the discharge component 144 is fixed on the inner wall of the cavity 117. Specifically, the discharge component 144 can be inserted into the slot on the inner wall of the cavity 117, or the discharge component 144 can be fixed on the inner wall of the cavity 117 by screws or other connectors, so as to ensure that the discharge component 144 can be accurately fixed in the predetermined working position.

[0196] In some embodiments of the present invention, the air purification device 100 may optionally include a power supply component disposed on the base 110, the power supply component including a positive electrode and a negative electrode, the positive electrode being connected to one of the dust collection assembly 120 and the discharge component 144, and the negative electrode being connected to the other of the dust collection assembly 120 and the discharge component 144.

[0197] Specifically, the power supply component is located within the controller 160.

[0198] In this embodiment, the air purification device 100 also includes a power supply component. One of the positive and negative electrodes of the power supply component is connected to the dust collection assembly 120, and the other is connected to the discharge component 144, so that the ions accumulated inside the dust collection assembly 120 and the ions released by the discharge component 144 have opposite polarities. The ions released by the discharge component 144 attach to the pollutants 200 in the electric field region, causing the pollutants 200 to carry a charge opposite to that of the dust collection assembly 120. This increases the adsorption force of the dust collection assembly 120 on the pollutants 200 based on the original Coulomb force, causing the pollutants 200 to move faster towards the dust collection surface 122, thereby improving the adsorption capacity of the dust collection assembly 120. This compensates for the deficiencies in electric field adsorption and solves the technical problems of insufficient Coulomb force on the pollutants 200, insufficient pollutant capture capacity, and poor purification effect in related technologies. This achieves the technical effect of optimizing the structure of the air purification device 100, improving its purification capacity, and enhancing the user experience.

[0199] like Figure 10 As shown, in some embodiments of the present invention, optionally, the dust collection assembly 120 includes: a protective plate 124, the number of protective plates 124 being N, where N is an integer greater than 1, the N protective plates 124 being stacked, and adjacent protective plates 124 being spaced apart; a conductive component 126, disposed between adjacent protective plates 124, the conductive component 126 being used to generate an electric field when energized, and the surface of the protective plate 124 facing away from the conductive component 126 being the dust collection surface 122.

[0200] In this embodiment, the structure of the dust collection assembly 120 is detailed. Specifically, the dust collection assembly 120 includes a protective plate 124 and a conductive component 126. Specifically, there are multiple protective plates 124, which are stacked along the thickness direction of the base 110, and adjacent protective plates 124 are spaced apart to form a gap between them. The conductive component 126 is disposed in the gap between adjacent protective plates 124, and the conductive component 126 can generate an electric field after being energized. On multiple protective plates 124, the surface facing away from the conductive component 126 is the dust collection surface 122. For example, when there are two protective plates 124, the outer surfaces of the two protective plates 124 form two dust collection surfaces 122. When there are three protective plates 124, the middle protective plate 124 faces the conductive component 126 on both sides and does not form a dust collection surface 122, while the outer surfaces of the two outer protective plates 124 form two dust collection surfaces 122. That is, increasing the number of protective plates 124 does not increase the number of dust collection surfaces 122.

[0201] Specifically, the air purification device 100 also includes a power supply component, which is disposed in the base 110. The power supply component includes a positive electrode and a negative electrode, and a conductive component 126 is connected to the positive electrode to supply a positive DC high voltage to the conductive component 126 through the power supply component. After the positive DC high voltage is supplied to the conductive component 126, a large number of negative ions can be stored in the conductive component 126, thereby forming an electric field. After the pollutants 200 move to the electric field region, they are polarized under the action of the electric field and are thus adsorbed onto the dust collection surface 122. During the process of approaching the dust collection surface 122, the closer to the dust collection surface 122, the stronger the adsorption force. Therefore, the pollutants 200 undergo a process of accelerating towards the dust collection surface 122.

[0202] Based on this, a first conductive layer is covered on the surface of the protective plate 124 facing the conductive component 126. By setting the first conductive layer, the electric field can be enhanced, thereby strengthening the adsorption capacity of the dust collection assembly 120 for pollutants 200. Specifically, the first conductive layer is a barium carbonate coating.

[0203] Specifically, the protective plate 124 is a silicon dioxide tempered glass plate. Silicon dioxide tempered glass plates have the advantages of high strength, strong corrosion resistance, and insulation, providing long-term and effective protection for the internal conductive components 126, thereby improving the reliability of the dust collection assembly 120 and reducing its failure rate. At the same time, its insulation properties can prevent leakage problems in the dust collection assembly 120, thus improving its safety.

[0204] Specifically, the conductive component 126 includes a conductive wire and a second conductive layer. The conductive wire is electrically connected to the power supply component, and the second conductive layer is wrapped around the conductive wire. By setting the second conductive layer, the conductivity of the conductive component 126 can be further improved, thereby increasing the strength of the electric field and enhancing the adsorption capacity of the dust collection assembly 120 for pollutants 200.

[0205] Specifically, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0206] Specifically, conductive foam is also provided between two adjacent protective plates 124. The conductive foam, together with conductive wires and a second conductive layer, fills the gap between the two adjacent protective plates 124.

[0207] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present invention, optionally, the base 110 includes a cavity 117, a first airflow port 118 and a second airflow port 119, the first airflow port 118 being connected to the second airflow port 119 through the cavity 117, and also includes an ion wind assembly 150 disposed within the cavity 117.

[0208] In this embodiment, the base 110 is also provided with a first airflow port 118 and a second airflow port 119. The first airflow port 118 is connected to the second airflow port 119 through the cavity 117, that is, the first airflow port 118, the cavity 117 and the second airflow port 119 are combined to form an airflow passage.

[0209] Building upon this, the air purifier 100 also includes an ionization air assembly 150, which is disposed within the cavity 117. When energized, the ionization air assembly 150 generates directionally moving ions within itself. These ions, during their directional movement, drive the flow of nearby gas, thereby generating a corresponding directional airflow. This airflow accelerates the airflow around the air purifier 100, thus enhancing air purification capabilities in conjunction with the dust collection assembly 120 and the discharge component 144. Furthermore, the directionally moving ions sterilize pollutants 200 in the airflow, reducing the concentration of toxic substances in the air and protecting user health.

[0210] like Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments of the present invention, optionally, the ion wind assembly 150 includes: a frame 152 including a wind duct 1522, the end of the wind duct 1522 being opposite to the first airflow port 118; an ion emitting component 154 disposed within the wind duct 1522; and an ion receiving component 156 disposed within the wind duct 1522 and opposite to the ion emitting component 154.

[0211] In this embodiment, the structure of the ion wind assembly 150 is detailed. The ion wind assembly 150 includes a frame 152, an ion emitting component 154, and an ion receiving component 156. The frame 152 is disposed in the cavity 117 and is connected to the base 110. A through air duct 1522 is provided inside the frame 152, and the outlet end of the air duct 1522 is opposite to the first airflow port 118. The ion emitting component 154 and the ion receiving component 156 are disposed within the frame 152, and the frame 152 can provide support and protection for the ion emitting component 154 and the ion receiving component 156. The ion receiving component 156 is located near the outlet end of the air duct 1522, and the ion receiving component 156 is located near the inlet end of the air duct 1522.

[0212] One of the ion emitting component 154 and the ion receiving component 156 is connected to the positive terminal of the power supply component, and the other is connected to the negative terminal of the power supply component. After being powered on, the ion emitting component 154 releases ions, which are captured by the ion receiving component 156, thereby forming a directional flow of ions and a directional flow of airflow. The airflow flows out of the base 110 through the outlet end of the air duct 1522 and the first airflow port 118 to form a circulation with the second airflow port 119.

[0213] like Figure 1 As shown, in some embodiments of the present invention, the air purification device 100 may optionally include: a controller 160 disposed on the base 110 and electrically connected to the dust collection assembly 120 and the discharge component 144; and a sensor disposed on the base 110 for detecting the concentration value of pollutants 200 in the air.

[0214] In this embodiment, the air purification device 100 also includes a controller 160 and a sensor. Both the controller 160 and the sensor are mounted on the base 110. The controller 160 is electrically connected to the dust collection assembly 120 and the discharge component 144, and the sensor is connected to the controller 160. During operation, the controller 160 obtains the concentration value of pollutants 200 in the air from the sensor, and then the controller 160 controls the start / stop and power of the dust collection assembly 120 according to the concentration value.

[0215] Specifically, when the air quality is poor, the dust collection component 120 should be turned on in time or its power should be increased, and when the air quality is good, the dust collection component 120 should be turned off in time or its power should be reduced.

[0216] When the air quality is poor, the first angle can be reduced by controlling the drive component 146, or the drive component 146 can be controlled to drive the third discharge needle 1446 to swing frequently. When the air quality is good, the first angle can be increased by controlling the drive component 146, or the discharge component 144 can be controlled to turn off.

[0217] Therefore, by setting up the controller 160 and sensors, the working state of the air purification device 100 can be adjusted in a targeted manner according to the air quality, ensuring that the working state of the dust collection component 120 and the discharge component 144 can match the actual environment, thereby achieving the technical effect of improving the intelligence level of the air purification device 100.

[0218] In this embodiment, the dust collection surface 122 is a plane or a smooth curved surface.

[0219] By setting the dust collection surface 122 as a plane, the size of the dust collection component 120 in the thickness direction can be reduced, which is conducive to realizing the ultra-thin design of the dust collection component 120, providing convenient conditions for the miniaturization and lightweight design of the air purification device 100, and reducing the difficulty of installing the air purification device 100 indoors.

[0220] By setting the dust collection surface 122 as a smooth curved surface, the area of ​​the dust collection surface 122 can be increased to improve the adsorption capacity of the dust collection component 120 for pollutants 200. On the other hand, the smooth curved surface can expand the electric field region generated by the dust collection component 120, thereby expanding the effective adsorption range of the dust collection component 120.

[0221] In some embodiments of the present invention, optionally, the discharge component 144 includes: a first discharge component, wherein the emitting end of the first discharge component is oriented in a first direction, and the first direction is parallel to the dust collection surface 122.

[0222] In this embodiment, the discharge component 144 includes a first discharge component located in front of the dust collection surface 122, with the emitting end of the first discharge component facing a first direction parallel to the dust collection surface 122. When the dust collection surface 122 is planar, the first discharge component is perpendicular to the normal direction of the dust collection surface 122. After being energized, the first discharge component releases ions along the first direction. These ions move to the electric field region and attach to the particles, thus charging the particles.

[0223] By setting a first discharge component parallel to the dust collection surface 122, the deviation between the trajectory of the released ions and the electric field area generated by the dust collection component 120 can be reduced, thereby increasing the possibility of pollutants 200 in the electric field area being attached by ions, and thus achieving the technical effect of improving the adsorption capacity of the air purification device 100 for pollutants 200.

[0224] In some embodiments of the present invention, optionally, the discharge component 144 includes: a second discharge component, wherein the emitting end of the second discharge component is oriented in a second direction, which is perpendicular to the dust collection surface 122.

[0225] In this embodiment, the discharge component 144 includes a second discharge component located in front of the dust collection surface 122. The emitting end of the second discharge component faces a second direction, which is perpendicular to the dust collection surface 122. When the dust collection surface 122 is planar, the second discharge component is parallel to the normal direction of the dust collection surface 122. After being energized, the second discharge component releases ions along the second direction. After moving to the electric field region, the ions attach to the particles, thereby charging the particles.

[0226] By setting a second discharge component perpendicular to the dust collection surface 122, a certain deviation can be made between the trajectory of the released ions and the electric field region generated by the dust collection component 120. This allows some of the released ions to enter the electric field region and be captured by the dust collection component 120, while other ions can move to areas outside the electric field region and sterilize the pollutants 200 outside the electric field region. Thus, while maintaining and improving the adsorption capacity of the dust collection component 120 for pollutants 200, the sterilization capacity of the discharge component 144 for airborne pollutants 200 is enhanced, enabling the air purification device 100 to perform both pollutant collection and sterilization functions. This achieves the technical effect of broadening the functionality of the air purification device 100 and improving its practicality and reliability.

[0227] In some embodiments of the present invention, optionally, the discharge component 144 includes: a third discharge component, the emitting end of the third discharge component is oriented in a third direction, and the angle between the third direction and the dust collection surface 122 is a first angle; the range of the first angle is: greater than or equal to 0° and less than or equal to 90°.

[0228] In this embodiment, the discharge component 144 includes a third discharge component located in front of the dust collection surface 122, with the emitting end of the third discharge component facing a third direction. The angle between the third direction and the dust collection surface 122 is between 0° and 90°. After being energized, the third discharge component releases ions along the third direction. After moving to the electric field region, the ions attach to the particles, thus charging the particles.

[0229] When the dust collection surface 122 is a flat surface or an outwardly curved surface, the electric field region formed is fan-shaped. By setting a third discharge component, the trajectory of ions in the electric field region can be extended by constructing a first included angle, thereby increasing the possibility of ions attaching to pollutants 200, and thus achieving the technical effect of improving the adsorption capacity of air purification equipment 100 for pollutants 200.

[0230] In some embodiments of the present invention, the third discharge component is optionally rotatably connected to the base 110 via a bracket 142; the bracket 142 can adjust the first included angle by rotation.

[0231] In this embodiment, the third discharge component is mounted on the bracket 142, and the bracket 142 is rotatably connected to the base 110. During operation, the orientation of the third discharge component can be adjusted by controlling the rotation of the bracket 142, thereby adjusting the size of the first included angle, wherein the adjustment range of the first included angle is greater than or equal to 0° and less than or equal to 90°.

[0232] By mounting the third discharge component on the rotatable bracket 142, its orientation can be adjusted to meet specific purification needs. Specifically, when the concentration of pollutants 200 in the air is high, rotating the bracket 142 reduces the first angle, thereby enhancing the adsorption capacity of the third discharge component on the dust collection assembly 120. Conversely, when the concentration of pollutants 200 in the air is low, rotating the bracket 142 increases the first angle, enhancing the sterilization effect of the third discharge component on the pollutants 200. This allows the enhanced and sterilization functions of the third discharge component to be adjusted according to actual needs. Alternatively, the overlap between the ion release area and the electric field area can be expanded by controlling the swing of the bracket 142, increasing the likelihood of pollutants 200 in the electric field area being attached by ions. This enhances the intelligence and practicality of the air purification equipment 100.

[0233] In some embodiments of the present invention, the air purification device 100 may optionally include a driving component 146 connected to the bracket 142 for driving the bracket 142 to rotate.

[0234] In this embodiment, the driving component 146 is fixed to the base 110, and the driving end of the driving component 146 is connected to the bracket 142. After being energized, the driving component 146 can drive the bracket 142 to rotate, thereby adjusting the size of the first included angle. By setting the driving component 146, the bracket 142 can be rotated by the driving component 146 to automatically adjust the orientation of the third discharge component, eliminating the need for the user to manually adjust the bracket 142. This achieves the technical effect of improving the automation level of the air purification equipment 100%.

[0235] Specifically, the driving component 146 is a motor, and the output shaft of the motor is connected to the rotating shaft of the third bracket 142. The motor drives the bracket 142 and the third discharge component to rotate synchronously through the rotating shaft.

[0236] like Figure 16 As shown, one embodiment of the present invention provides a control method for an air purification device. The air purification device includes a base, a dust collection assembly, and a discharge component. The dust collection assembly is disposed on the base, and the discharge component is rotatably connected to the base. The control method for the air purification device includes:

[0237] Step 1602: Obtain the concentration values ​​of pollutants in the air;

[0238] Step 1604: Control the rotation of the discharge component according to the concentration value.

[0239] In this embodiment, the air purification device is used to treat pollutants in the air to reduce the pollutant content in the air. The air purification device includes a base and a dust collection assembly, the base being used to position, support, and protect the dust collection assembly.

[0240] The dust collection component includes a dust collection surface, which is housed within a base that avoids the dust collection surface, allowing it to be exposed to the air. When energized, the dust collection component accumulates ions, generating an electric field. This electric field forms a region in front of the dust collection surface. Pollutants within this region are polarized and move towards the dust collection surface under the influence of Coulomb forces until they are adsorbed onto the surface. This adsorption reduces the concentration of pollutants within the electric field region. Due to the concentration difference, pollutants outside the electric field region migrate to the lower concentration region, thereby reducing the overall concentration of pollutants in the environment and achieving air purification.

[0241] In addition, the air purification device also includes a discharge component. The discharge end of the discharge component releases ions into the area facing the dust collection surface. These released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component. One of the positive and negative electrodes of the power supply component is connected to the dust collection assembly, and the other is connected to the discharge component, so that the ions accumulated inside the dust collection assembly and the ions released by the discharge component have opposite polarities.

[0242] The ions released by the discharge component attach to the pollutants in the electric field area, so that the pollutants have an opposite charge to the dust collection component. This increases the adsorption force of the dust collection component on the pollutants on the basis of the original Coulomb force, causing the pollutants to move faster toward the dust collection surface, thereby improving the adsorption capacity of the dust collection component and making up for the shortcomings of electric field adsorption.

[0243] The discharge component is rotatably connected to the base, and its orientation can be adjusted by controlling its rotation, thereby adjusting the direction of ion transmission. Specifically, the discharge component is rotatably connected to the base via a bracket, and the orientation of the third discharge needle on the bracket can be adjusted by controlling the rotation of the bracket.

[0244] Based on this, the control method for the air purification equipment is as follows: After the air purification equipment is turned on based on the purification command, the concentration value of pollutants in the air is obtained through sensors. After obtaining the concentration value, the discharge component is controlled to rotate according to the concentration value, so that the discharge component faces the target direction, or the discharge component oscillates at the target frequency.

[0245] By defining the aforementioned control steps, the discharge component can rotate or oscillate according to the density of pollutants, ensuring that its operating state meets the cleaning requirements corresponding to the current pollutant concentration, thereby enhancing the air purification equipment's ability to capture pollutants. This solves the technical problems of insufficient Coulomb force on pollutants, inadequate pollutant capture capacity, and poor purification effect existing in related technologies. Ultimately, it optimizes the control process of air purification equipment, improves its purification capacity, and enhances the user experience.

[0246] like Figure 17 As shown, in some embodiments of the present invention, optionally, the step of controlling the rotation of the discharge component according to the concentration value includes:

[0247] Step 1702: Determine the target direction based on the concentration value;

[0248] Step 1704: Control the discharge component to rotate so that the discharge component faces the target direction.

[0249] In this embodiment, the step of controlling the rotation of the discharge component based on the concentration value is refined. Specifically, after obtaining the concentration value, the corresponding target direction is determined based on the concentration value. After determining the target direction, the discharge component is rotated so that the third discharge needle on the discharge component faces the target direction.

[0250] By defining the aforementioned control steps, the dust collection component can adjust its orientation based on the pollutant concentration, thereby automatically adjusting the overlap between the ion-covered area and the electric field area, as well as the incident direction of the ions. This adjusts the difficulty of ion capture by the dust collection component, automatically distributing the enhancement effect of the discharge component on the dust collection component and the sterilization effect on air pollutants. Ultimately, this improves the automation and intelligence of the air purification equipment, enhancing its air purification capabilities.

[0251] In some embodiments of the present invention, optionally, the dust collection component includes a dust collection surface, which can generate an electric field when energized, and the dust collection surface is used to collect pollutants in the air through the electric field; the angle between the target direction and the dust collection surface is a first angle; the first angle is negatively correlated with the concentration value.

[0252] In this embodiment, the discharge component includes a support and a third discharge needle. The emitting end of the third discharge needle is oriented in a third direction, and the angle between the third direction and the dust collection surface is a first angle; the first angle is greater than or equal to 0° and less than or equal to 90°. The third discharge needle is rotatably connected to the base via the support; the support can be adjusted by rotation to change the first angle. By mounting the third discharge needle on a rotatable support, the orientation of the third discharge needle can be adjusted according to actual purification needs.

[0253] Specifically, when the pollutant concentration in the air is high, the first angle is reduced by rotating the support to enhance the adsorption capacity of the third discharge needle on the dust collection component. Conversely, when the pollutant concentration is low, the first angle is increased by rotating the support to enhance the sterilization effect of the third discharge needle on the air pollutants. This allows the enhancement and sterilization functions of the third discharge needle to be adjusted according to actual needs. Alternatively, the overlap between the ion release area and the electric field area can be expanded by controlling the swing of the support, thereby increasing the likelihood of pollutants in the electric field area being attached by ions. This achieves the technical effect of improving the intelligence and practicality of the air purification equipment.

[0254] In some embodiments of the present invention, optionally, the step of controlling the rotation of the discharge component according to the concentration value includes:

[0255] Based on a concentration value greater than or equal to a first threshold, the oscillation of the discharge component is controlled.

[0256] Based on the concentration value being less than the first threshold, the discharge component is controlled to stop oscillating.

[0257] In this embodiment, the step of controlling the rotation of the discharge component based on the concentration value is refined. Specifically, after obtaining the concentration value, it is compared with a first threshold. If the concentration value is greater than or equal to the first threshold, the discharge component is controlled to oscillate. During the oscillation, the angle between the third discharge needle on the discharge component and the dust collection surface ranges from 0° to 90°. This oscillation increases the overlap area between the ion coverage area and the electric field area, reducing the difficulty for ions to adhere to pollutants in the discharge area. Correspondingly, when the concentration value is less than the first threshold, the discharge component stops oscillating to avoid the oscillating discharge needle affecting the sterilization effect of the discharge component on pollutants and to reduce unnecessary energy consumption. This achieves the technical effect of improving the intelligence level and practicality of the air purification equipment.

[0258] like Figure 18 As shown, in some embodiments of the present invention, optionally, the step of controlling the oscillation of the discharge component includes:

[0259] Step 1802: Determine the target frequency based on the concentration value;

[0260] Step 1804: Control the discharge component to oscillate according to the target frequency.

[0261] In this embodiment, the steps for controlling the oscillation of the discharge component are detailed. Specifically, when the concentration value is greater than a first threshold, a target frequency is first determined based on the concentration value, and then the discharge component is controlled to oscillate according to the target frequency. This ensures that the oscillation frequency of the discharge component matches the current air quality, ensuring that the air purification equipment can meet the air purification requirements. This, in turn, achieves the technical effect of improving the intelligence level and practicality of the air purification equipment.

[0262] In some embodiments of the present invention, the target frequency is optionally positively correlated with the concentration value.

[0263] In this embodiment, the target frequency is positively correlated with the concentration value. That is, the higher the concentration value, the higher the oscillation frequency of the discharge component, and the lower the concentration value, the lower the oscillation frequency of the discharge component. When the concentration value is high, controlling the high-frequency oscillation of the discharge component allows pollutants entering the electric field region to be attached by ions in a timely manner, thereby accelerating the rate at which pollutants are captured by the dust collection surface. When the concentration value is low, controlling the low-frequency oscillation of the discharge component can reduce energy consumption while meeting the requirements for pollutant attachment. This achieves the technical effect of improving the intelligence level and practicality of the air purification equipment.

[0264] In some embodiments of the present invention, the control method for the air purification device may optionally further include:

[0265] Based on a concentration value greater than or equal to the second threshold, the dust collection component and the discharge component are controlled to turn on.

[0266] Based on the concentration value being less than the second threshold, the dust collection component and discharge component are shut down.

[0267] In this embodiment, after obtaining the concentration value, the relationship between the concentration value and the second threshold is compared. If the concentration value is greater than or equal to the second threshold, it indicates that the pollutant content in the air is high and purification is required. The dust collection component and discharge component are then activated to start the purification mode of the air purifier. Conversely, if the concentration value is less than the second threshold, it indicates that the pollutant content in the air is low, meeting the user's air cleanliness requirements. The dust collection component and discharge component are then deactivated to exit the purification mode of the air purifier. The second threshold is less than or equal to the first threshold; specifically, the second threshold can be selected as 75 μg / m².

[0268] By limiting the above control steps, the automatic start and stop of the air purification mode is achieved, thereby maintaining the concentration of pollutants in the current environment below the second threshold. This results in improved automation and intelligence of the air purification equipment, enhanced purification capacity, and reduced energy consumption.

[0269] like Figure 19As shown in one embodiment of this application, the control flow of the air purification device is as follows:

[0270] Step 1902: Activate purification mode;

[0271] Step 1904: Detect the concentration of pollutants;

[0272] Step 1906: Is the concentration value ≥75μg / m2?

[0283] like Figure 20 As shown, one embodiment of the present invention provides a control device 2000 for an air purification device. The air purification device includes a base, a dust collection assembly, and a discharge component. The dust collection assembly is disposed on the base, and the discharge component is rotatably connected to the base. The control method of the air purification device includes:

[0284] The acquisition module 2002 is used to acquire the concentration values ​​of pollutants in the air;

[0285] Control module 2004 is used to control the rotation of the discharge component according to the concentration value.

[0286] In this embodiment, the air purification device is used to treat pollutants in the air to reduce the pollutant content in the air. The air purification device includes a base and a dust collection assembly, the base being used to position, support, and protect the dust collection assembly.

[0287] The dust collection component includes a dust collection surface, which is housed within a base that avoids the dust collection surface, allowing it to be exposed to the air. When energized, the dust collection component accumulates ions, generating an electric field. This electric field forms a region in front of the dust collection surface. Pollutants within this region are polarized and move towards the dust collection surface under the influence of Coulomb forces until they are adsorbed onto the surface. This adsorption reduces the concentration of pollutants within the electric field region. Due to the concentration difference, pollutants outside the electric field region migrate to the lower concentration region, thereby reducing the overall concentration of pollutants in the environment and achieving air purification.

[0288] In addition, the air purification device also includes a discharge component. The discharge end of the discharge component releases ions into the area facing the dust collection surface. These released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component. One of the positive and negative electrodes of the power supply component is connected to the dust collection assembly, and the other is connected to the discharge component, so that the ions accumulated inside the dust collection assembly and the ions released by the discharge component have opposite polarities.

[0289] The ions released by the discharge component attach to the pollutants in the electric field area, so that the pollutants have an opposite charge to the dust collection component. This increases the adsorption force of the dust collection component on the pollutants on the basis of the original Coulomb force, causing the pollutants to move faster toward the dust collection surface, thereby improving the adsorption capacity of the dust collection component and making up for the shortcomings of electric field adsorption.

[0290] The discharge component is rotatably connected to the base, and its orientation can be adjusted by controlling its rotation, thereby adjusting the direction of ion transmission. Specifically, the discharge component is rotatably connected to the base via a bracket, and the orientation of the third discharge needle on the bracket can be adjusted by controlling the rotation of the bracket.

[0291] Based on this, the control device 2000 of the air purification equipment includes an acquisition module 2002 and a control module 2004. After the air purification equipment is turned on based on the purification command, the acquisition module 2002 acquires the concentration value of pollutants in the air through sensors. After acquiring the concentration value, the control module 2004 controls the discharge component to rotate according to the concentration value, so that the discharge component faces the target direction, or makes the discharge component oscillate at the target frequency.

[0292] By limiting the aforementioned control device, the discharge component can rotate or oscillate according to the density of pollutants, ensuring that the working state of the discharge component meets the cleaning requirements corresponding to the current concentration of pollutants, thereby improving the air purification equipment's ability to capture pollutants. This solves the technical problems of insufficient Coulomb force on pollutants, inadequate pollutant capture capacity, and poor purification effect existing in related technologies. Ultimately, it optimizes the control process of air purification equipment, enhances its purification capacity, and improves the user experience.

[0293] like Figure 21 As shown, one embodiment of the present invention provides a control device 2100 for an air purification device. The control device 2100 includes: a memory 2102, which stores programs or instructions; and a processor 2104, which executes the programs or instructions stored in the memory 2102 to implement the steps of the control method for the air purification device as described in any of the above embodiments.

[0295] One embodiment of the present invention provides a readable storage medium storing a program or instructions that, when executed by a processor, implement the steps of the control method for the air purification device as described in any of the above embodiments.

[0296] In this embodiment, a readable storage medium is defined.

[0297] One embodiment of the present invention provides an air purification device, which includes: a control device as described in any of the above embodiments, or a readable storage medium as described in the above embodiments.

[0298] In this embodiment, an air purification device is defined, which possesses the advantages of the control device of the air purification device in any of the above embodiments, or the advantages of the readable storage medium in the above embodiments. Therefore, it can achieve the technical effects that the control device of the air purification device in any of the above embodiments can achieve, or the technical effects that the readable storage medium in the above embodiments can achieve. To avoid repetition, further details are omitted here.

[0299] like Figure 22 As shown in the figure, the electric field region generated by the dust collection assembly 120 after being powered on is illustrated.

[0300] In a direction from far to near, the front side of the dust collection surface 122 is divided into multiple fan-shaped sub-regions.

[0301] ρ1 is the concentration of pollutants in the first sub-region, ρ2 is the concentration of pollutants in the second sub-region, ρ3 is the concentration of pollutants in the third sub-region, and ρ4 is the concentration of pollutants in the fourth sub-region.

[0302] Among them, ρ1<ρ2<ρ3<ρ4.

[0303] Arrow d indicates the direction of pollutant movement. V1 is the speed of pollutant movement in the first sub-region, V2 is the speed of pollutant movement in the second sub-region, V3 is the speed of pollutant movement in the third sub-region, and V4 is the speed of pollutant movement in the fourth sub-region.

[0304] Among them, V1 > V2 > V3 > V4, that is, the greater the concentration difference, the faster the movement speed.

[0305] like Figure 23 As shown, the air purification device provided in this application includes a dust collection component, an ion wind component, and a discharge component. The dust collection component includes a protective plate and a conductive component. The protective plate is disposed on both sides of the conductive component. The conductive component is made of a metallic conductive material or a non-metallic conductive material, and can store a large number of negative ions by utilizing its large specific area.

[0306] Conductive metallic materials include copper, aluminum, silver, iron, tin, gold, nickel, lead, magnesium, zinc, molybdenum, yttrium, tungsten, and cobalt. Non-metallic conductive materials include graphite and graphene. The conductive component can also be a combination or compound of conductive metallic and / or non-metallic materials. Optionally, the conductive component is a graphene aluminum wire layer.

[0307] The protective plate can be made of at least one of glass, plastic, or rubber. The protective plate acts as an adsorption structure, utilizing the Coulomb force between ions. When an object approaches the negatively charged "glass layer," an adsorption effect occurs. Air pollutants such as PM2.5, dust, and volatile substances can move towards the protective plate in the direction indicated by arrow M, thus adsorbing the air pollutants onto the surface of the protective plate.

[0308] The ion wind component and / or discharge component can deliver negative ions to the dust collection component in the direction indicated by arrow N, and can emit an ion beam in the direction indicated by arrow O, thereby achieving membrane rupture, sterilization and disinfection through the ion beam.

[0309] Furthermore, based on Coulomb's law, the formula for calculating Coulomb force is: F = K × Q1 × Q2 / r 2 Where Q1 and Q2 are the charges of the two objects, r is the distance between the centers of the two objects (the distance between Q1 and Q2), and K is a constant, K = 8.987 × 10⁻⁶. 9 The unit is Newton-meter. 2 / library 2 (N·m 2 / C 2 Coulomb force is the interaction force between stationary charged bodies.

[0310] A charged body can be considered as being composed of many point charges. The interaction force between each pair of stationary point charges follows Coulomb's law, which states that in a vacuum, the magnitude of the interaction force between two stationary point charges Q1 and Q2 is directly proportional to the product of Q1 and Q2 and inversely proportional to the square of the distance r between point charges Q1 and Q2. The direction of the force is along the line connecting them. Like charges repel each other, and unlike charges attract each other.

[0311] Ideal insulating media have no free charges. However, actual dielectrics always contain a small amount of free charges. Various substances can generally be considered as objects where the centers of positive and negative electrons coincide. Under normal circumstances, the bound positive and negative charges within a dielectric without an electric field cancel each other out on average, and macroscopically, no electrical property is observed. Under the influence of an external electric field, the localized movement of bound charges causes macroscopic electrical properties to appear, resulting in charges appearing on the surface and in uneven areas within the dielectric. This phenomenon is called polarization, and the resulting charges are called polarization charges. Conductive components generate an electric field, which induces polarization charges in substances within that field (such as air pollutants). Then, based on the principle of attraction between opposite charges, these substances are adsorbed onto the surface of the dust collection component.

[0312] Furthermore, when the dust collection component is energized, it generates an electric field. The particles move in the space based on the concentration difference. When they reach the electric field area, they are adsorbed by the dust collection component. There will always be a low concentration area near the dust collection component, which will attract the particles.

[0313] When air pollutants move into the electric field region of the dust collection component, they are polarized and thus adsorbed onto the dust collection component. There is an acceleration process when they approach the dust collection component.

[0314] The power supply component has positive and negative terminals. One terminal is connected to the dust collection component, and the other is connected to the discharge component. The discharge component releases electrons into the air, causing air pollutants to become charged with the opposite charge to the dust collection component, thus accelerating their adsorption onto the dust collection component. This improves purification efficiency, and the discharge component also has a bactericidal effect by charging the air pollutants.

[0315] One of the positive and negative terminals of the power supply component is connected to the ion generating electrode of the ion wind component, and the other is connected to the ion receiving electrode of the ion wind component. An airflow channel must be provided, and the ion generating electrode and the ion receiving electrode are installed in the airflow channel to sterilize the airflow.
