Technical Field

[0002] The present invention relates to the technical field of air purification, and in particular to an air purification device and a control method, device and storage medium thereof. Background Art

[0003] In the related art, an air purifier can absorb pollutants in the air through the electric field generated after being powered on, so as to achieve the purpose of air purification.

[0004] However, in actual operation, the electric field has limited polarization ability for pollutants. Some pollutants still cannot be successfully polarized or the Coulomb force acting on the polarized pollutants does not meet the standard, resulting in technical problems such as insufficient pollutant capture ability and poor purification effect of the air purifier. Summary of the invention

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

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

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

[0012] In view of this, the first aspect of the present invention provides an air purification device, which includes: a dust collecting component, the dust collecting component includes a dust collecting surface, the dust collecting component can generate an electric field when powered on, and the dust collecting surface is used to collect pollutants in the air through the electric field; a discharge component, the discharge component is used to discharge toward the area facing the dust collecting surface; wherein the dust collecting component is used to connect one of the positive electrode and the negative electrode, and the discharge component is used to connect the other of the positive electrode and the negative electrode.

[0013] The present application defines an air purification device, which is used to process pollutants in the air to achieve the effect of reducing the content of pollutants in the air. The air purification device includes a dust collection component.

[0014] The dust collecting component includes a dust collecting surface, which can be exposed to the air. After being powered on, the dust collecting component accumulates ions inside, and an electric field can be generated under the action of the accumulated ions. The electric field forms an electric field area on the front side of the dust collecting surface. The pollutants in the electric field area will be polarized, and the polarized pollutants will move toward the dust collecting surface under the action of Coulomb force until the pollutants are adsorbed on the dust collecting surface. Under the adsorption effect, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect.

[0015] On this basis, the air purification device also includes a discharge component, the discharge end of the discharge component and the area facing the dust collecting surface release ions, and the released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collecting component, and the other is connected to the discharge component, so that the polarity of the ions accumulated in the dust collecting component and the ions released by the discharge component are opposite.

[0016] The ions released by the discharge component will adhere to the pollutants in the electric field area, so that the pollutants carry the opposite charge to the dust collection component, thereby increasing the adsorption force of the dust collection component on the pollutants on the basis of the original Coulomb force, accelerating the movement of pollutants to the dust collection surface, thereby improving the adsorption capacity of the dust collection component, making up for the shortcomings of electric field adsorption, and solving the technical problems of the Coulomb force on pollutants that does not meet the standards, insufficient pollutant capture capacity, and poor purification effect in related technologies. Then the technical effect of optimizing the structure of air purification equipment, improving the purification capacity of air purification equipment, and improving the user experience is achieved. At the same time, the ions released by the discharge component can also play a bactericidal role to reduce the content of toxic substances in the air and protect the health of users.

[0017] On this basis, the dust collection component proposed in this application collects pollutants through an electric field, and the collected pollutants adhere to the dust collection surface. After use, the pollutants can be removed by washing or wiping the dust collection surface, eliminating the need for frequent replacement of filter materials, thereby reducing the cost of using air purification equipment. At the same time, the noise generated by the dust collection component when powered on is relatively small, which can further improve the user experience.

[0018] Specifically, the dust collection component proposed in the present application can actively absorb pollutants in the air with the help of the electric field generated by itself, without the need for circulating airflow to achieve air purification function, thereby saving 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 collecting component and the discharge component can be a split structure, the dust collecting component and the discharge component are independently powered, and the positions of the dust collecting component and the discharge component can be freely adjusted according to the scene requirements. During use, the dust collecting component is arranged first, and then the discharge component is placed in the electric field area generated by the dust collecting component to ensure that the discharge component can effectively cooperate with the dust collecting component to absorb pollutants in the air.

[0020] Specifically, the dust collecting assembly and the discharge component can be an integrated structure, for example, the dust collecting assembly and the discharge component are directly connected, or the dust collecting assembly and the discharge component are fixed together on the same base. In this integrated structure, the relative positions of the dust collecting assembly and the discharge component are locked, which can ensure that the discharge component can discharge into the electric field area generated by the dust collecting assembly.

[0021] Among them, the pollutants mentioned in this application are mainly solid particle pollutants. Solid particle pollutants in the air include dust, smoke, particulate matter, bacteria, viruses, etc. Their diameters vary and can generally be divided into the following categories according to their diameters:

[0022] Visible particles: particles with a diameter of 10 microns or less, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0023] Fine particulate matter: Particles with a diameter of less than or equal to 2.5 microns, which cannot be seen by the naked eye but have a greater impact on human health, such as automobile exhaust and factory waste gas.

[0024] Ultrafine particles: particles with a diameter of 0.1 microns or less, which cannot be seen by 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 of the air purification device in the above 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 an emission end, the connection end is used to connect the other of the positive electrode and the negative electrode, and the emission end is used for discharging.

[0027] In this technical solution, the discharge component is a discharge needle, which includes a connecting end and an 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 power is applied, the discharge needle can release ions, and the ions can attach to pollutants in the electric field area.

[0028] Specifically, the discharge component includes a discharge needle or a discharge brush.

[0029] In some technical solutions of the present invention, optionally, the air purification device also includes: a first voltage regulator connected to the dust collecting component, the first voltage regulator is used to connect to the power supply, and the first voltage regulator is used to adjust the potential of the dust collecting component to be higher than the ground potential; a second voltage regulator connected to the connection end, the second voltage regulator is used to connect to the power supply, and the second voltage regulator is used to adjust the potential of the discharge component to be lower than the ground potential.

[0030] In this technical solution, the dust collecting component and the discharge component can be powered independently, so as to realize the split design of the dust collecting component and the discharge component. Specifically, the dust collecting component is connected to the power supply through the first voltage regulator. Under the voltage regulation of the first voltage regulator, the potential of the dust collecting component is higher than the ground potential, so that a positive voltage is formed between the dust collecting component and the zero pole. Correspondingly, the discharge component is connected to the power supply through the second voltage regulator. Under the voltage regulation of the second voltage regulator, the potential of the discharge component is lower than the ground potential, so that a negative voltage is formed between the discharge component and the zero pole. The discharge component carrying a negative voltage can release negative ions into the air, thereby making the pollutants in the air negatively charged. After the pollutants carry negative electricity, they will move toward the dust collecting component carrying positive electricity, and finally be captured by the dust collecting component, thereby removing the pollutants in the air. In some technical solutions of the present invention, optionally, the air purification device also includes: a base, and the dust collecting component and the discharge component are arranged on the base.

[0031] In some technical solutions of the present invention, optionally, 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 toward the discharge port it faces.

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

[0034] In this technical solution, the discharge needle includes a first discharge needle, which is located in front of the dust collecting surface, and the emission end of the first discharge needle is oriented in a first direction, which is parallel to the dust collecting surface. When the dust collecting surface is a plane, the first discharge needle is perpendicular to the normal direction of the dust collecting surface. After power is turned on, the first discharge needle releases ions along the first direction, and after moving to the electric field area, the ions adhere to the particles to charge the particles.

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

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

[0037] In this technical solution, the discharge needle includes a second discharge needle, which is located in front of the dust collecting surface, and the emission end of the second discharge needle is oriented in a second direction, which is perpendicular to the dust collecting surface. When the dust collecting surface is a plane, the second discharge needle is parallel to the normal direction of the dust collecting surface. After power is turned on, the second discharge needle releases ions along the second direction, and after moving to the electric field area, the ions adhere to the particles to charge the particles.

[0038] By setting a second discharge needle perpendicular to the dust collecting surface, there can be a certain deviation between the movement trajectory of the released ions and the electric field area generated by the dust collecting component, so that some of the released ions can enter the electric field area and eventually be captured by the dust collecting component, while the other part of the ions can move to the area outside the electric field area and sterilize the pollutants outside the electric field area. Therefore, on the basis of maintaining the improvement of the dust collecting component's adsorption capacity for pollutants, the discharge component's sterilization ability for pollutants in the air is enhanced, so that the air purification equipment can take into account both the collection of pollutants and sterilization. This achieves the technical effect of broadening the functions of air purification equipment and improving the practicality and reliability of air purification equipment.

[0039] In some technical solutions of the present invention, optionally, the discharge needle includes: a third discharge needle, the emission end of the third discharge needle is directed in a third direction, and the angle between the third direction and the dust collecting 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 collecting surface, and the emission end of the third discharge needle is oriented in the third direction, and the angle between the third direction and the dust collecting surface is between 0° and 90°. After power is turned on, the third discharge needle releases ions along the third direction, and after the ions move to the electric field area, they attach to the particles to charge the particles.

[0041] When the dust collecting surface is a plane or an outwardly extended smooth curved surface, the electric field area formed is fan-shaped. By setting a third discharge needle, the movement trajectory of ions in the electric field area can be extended by constructing the first angle, thereby increasing the possibility of ions attaching to pollutants, thereby achieving the technical effect of improving the adsorption capacity of air purification equipment for pollutants.

[0042] In some technical solutions of the present invention, optionally, the bracket can adjust the first angle by rotating.

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

[0044] By setting the third discharge needle on a rotatable bracket, the direction of the third discharge needle can be adjusted according to the actual purification needs. Specifically, when the pollutant content in the air is high, the first angle is reduced by rotating the bracket to increase the enhancement of the adsorption capacity of the dust collecting component by the third discharge. Correspondingly, when the pollutant content in the air is low, the first angle is increased by rotating the bracket to enhance the sterilization effect of the third discharge on the pollutants in the air, so that the strengthening function and sterilization function of the third discharge needle can be adjusted according to actual needs. Or the overlapping area between the release area of ​​ions and the electric field area can be expanded by controlling the swing of the bracket, thereby increasing the possibility of pollutants in the electric field area being attached by ions. Thereby achieving the technical effect of improving the intelligence level of air purification equipment and improving the practicality of air purification equipment.

[0045] In some technical solutions of the present invention, optionally, the air purification device further includes: a driving component connected to the bracket and used to drive 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. After the driving component is powered on, it can drive the bracket to rotate to adjust the size of the first angle. By setting the driving component, the bracket can be driven to rotate by the driving component to automatically adjust the direction of the third discharge needle, eliminating the need for the user to manually adjust the bracket. This achieves the technical effect of improving the degree of automation of the air purification equipment.

[0047] Specifically, the driving component is a motor, the output shaft of the motor is connected to the rotating shaft of the third bracket, and 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, there are multiple discharge needles; the multiple discharge needles are arranged side by side on the bracket.

[0049] In this technical solution, a plurality of discharge needles are arranged on the bracket, and the plurality of discharge needles are arranged side by side on the bracket. By arranging a plurality of discharge needles side by side on the bracket, the coverage 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 in the electric field area being attached by the ions, and achieving the technical effect of improving the adsorption capacity of the dust collection component for pollutants.

[0050] In some technical solutions of the present invention, optionally, the air purification device also includes: a base, and the dust collecting component and the discharge component are arranged on the base.

[0051] In this technical solution, the air purification device also includes a base, and the dust collecting component and the discharge component are installed on the base. The base is used to provide positioning and support for the dust collecting component and the discharge component, and at the same time lock the relative position between the dust collecting component and the discharge component.

[0052] At the same time, the base has a larger contact surface and a lower 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 disposed in a cavity within the base and connected to the base.

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

[0055] Specifically, the driving component is fixed on 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, the base is also provided with a discharge port, which is connected to the cavity in the base. On this basis, a discharge component is arranged in the cavity, and the discharge end of the discharge component is opposite to 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 to the inner wall of the cavity by screws or other connectors to ensure that the discharge component can be accurately fixed in a predetermined working position.

[0060] In some technical solutions of the present invention, optionally, the air purification device also includes: a power supply component, which is arranged on the base, and the power supply component includes a positive electrode and a negative electrode, the positive electrode is connected to one of the dust collecting component and the discharge component, and the negative electrode is connected to the other of the dust collecting component and the discharge component.

[0061] In this technical solution, the air purification device also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collecting component, and the other is connected to the discharge component, so that the ions accumulated inside the dust collecting component and the ions released by the discharge component have opposite polarity. The ions released by the discharge component will adhere to the pollutants in the electric field area, so that the pollutants carry the opposite charge to the dust collecting component, thereby increasing the adsorption force of the dust collecting component on the pollutants on the basis of the original Coulomb force, accelerating the movement of pollutants to the dust collecting surface, thereby improving the adsorption capacity of the dust collecting component, making up for the shortcomings of electric field adsorption, and solving the technical problems of the Coulomb force on the pollutants not meeting the standards, insufficient pollutant capture capacity, and poor purification effect existing in the related technology. Then, the technical effect of optimizing the structure of the air purification equipment, improving the purification capacity of the air purification equipment, and improving the user experience is achieved.

[0062] In some technical schemes of the present invention, optionally, the dust collecting assembly includes: a guard plate, the number of the guard plates is N, N is an integer greater than 1, the N guard plates are stacked, and two adjacent guard plates are spaced apart; a conductive component, arranged between two adjacent guard plates, the conductive component is used to generate an electric field when power is supplied, and the surface of the guard plate facing away from the conductive component is a dust collecting surface.

[0063] In this technical solution, the structure of the dust collecting assembly is refined. Specifically, the dust collecting assembly includes a guard plate and a conductive component. Specifically, there are multiple guard plates, and the multiple guard plates are stacked along the thickness direction of the base, and two adjacent guard plates are spaced apart to form a gap between two adjacent guard plates. The conductive component is arranged in the gap between two adjacent guard plates, and the conductive component can generate an electric field after being energized. On the multiple guard plates, the surface facing away from the conductive component is the dust collecting surface. For example, when the number of guard plates is two, the outer side surfaces of the two guard plates form two dust collecting surfaces. When the number of guard plates is three, the two middle guard plates are both facing the conductive component and do not form a dust collecting surface. The outer side surfaces of the guard plates on both sides form two dust collecting surfaces, that is, increasing the number of guard plates will not increase the number of dust collecting surfaces.

[0064] Specifically, the air purification device also includes a power supply component, which is arranged in the base. The power supply component includes a positive electrode and a negative electrode. The conductive component is connected to the positive electrode so that positive DC high voltage is passed to the conductive component through the power supply component. After the positive DC high voltage is passed to the conductive component, a large number of negative ions can be stored in the conductive component, thereby forming an electric field. After the pollutants move to the electric field area, they are polarized under the action of the electric field and are adsorbed onto the dust collecting surface. In the process of approaching the dust collecting surface, the closer the distance to the dust collecting surface, the stronger the adsorption force, so the pollutants have a process of accelerating movement toward the dust collecting surface.

[0065] On this basis, the surface of the guard plate facing the conductive component is covered with a first conductive layer, and the first conductive layer can enhance the electric field to strengthen the adsorption capacity of the dust collecting component to pollutants. Specifically, the first conductive layer is a barium carbonate coating.

[0066] Specifically, the protective plate is a silicon dioxide tempered glass plate, which has the advantages of high strength, strong corrosion resistance and insulation, and can provide long-term and effective protection for the internal conductive parts, thereby improving the reliability of the dust collection component and reducing the failure rate of the dust collection component. At the same time, the insulation property can avoid the leakage problem of the dust collection component, thereby improving the safety of the dust collection component.

[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. The second conductive layer is wrapped around the outside of the conductive wire. By setting the second conductive layer, the conductive performance of the conductive component can be further improved, thereby increasing the strength of the electric field to enhance 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, a conductive foam is arranged between two adjacent guard plates, and the conductive foam cooperates with the conductive thread and the second conductive layer to fill the gap between the two adjacent guard plates.

[0070] In some technical solutions of the present invention, optionally, the base includes a cavity, a first air flow port and a second air flow port, the first air flow port is connected with the second air flow port through the cavity, and also includes: an ion wind component disposed in the cavity.

[0071] In this technical solution, a first air flow opening and a second air flow opening are also provided on the base, and the first air flow opening is connected with the second air flow opening through the cavity, that is, the first air flow opening, the cavity and the second air flow opening are combined into an air flow passage.

[0072] On this basis, the air purification device also includes an ion wind component, which is arranged in the cavity. When the ion wind component is powered on, ions that move in a direction are generated inside the component. The ions can drive the nearby gas to flow during the directional movement, thereby generating a corresponding directional airflow. On the one hand, this airflow can accelerate the air flow near the air purification device, thereby cooperating with the dust collection component and the discharge component to improve the air purification capacity. On the other hand, the directional flow of ions can sterilize the pollutants in the driven airflow to reduce the content of toxic substances in the air and protect the health of users.

[0073] In some technical solutions of the present invention, optionally, the ion wind component includes: a frame, including an air duct, the end of the air duct is opposite to the first air flow outlet; an ion emitting component, arranged in the air duct; and an ion receiving component, arranged in the air duct and opposite to the ion emitting component.

[0074] In this technical solution, the structure of the ion wind component is refined, and the ion wind component includes a frame, an ion generating component and an ion receiving component. The frame is arranged in the cavity, and the frame is connected to the base. A through air duct is arranged in the frame, and the outlet end of the air duct is opposite to the first air flow outlet. The ion emitting component and the ion receiving component are arranged in the frame, and the frame can provide support and protection for the ion emitting component and the ion receiving component. Among them, the ion receiving component is arranged at a position close to the outlet end of the air duct, and the ion receiving component is arranged at a position close to the inlet end of the air duct.

[0075] One of the ion emitting component and the ion receiving component is connected to the positive electrode of the power supply component, and the other is connected to the negative electrode of the power supply component. After power is turned on, the ion emitting component releases ions, and the released ions are captured by the ion receiving component, thereby forming directional flow of ions and directional flow of airflow. The airflow flows out of the base through the outlet end of the air duct and the first airflow outlet to form a cycle in conjunction with the second airflow outlet.

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

[0077] In this technical solution, the air purification device also includes a controller and a sensor, both of which are arranged on a base, the controller is electrically connected to the dust collection component and the discharge component, and the sensor is connected to the controller. During operation, the controller obtains the concentration value of pollutants in the air from the sensor, and then controls the start and stop and power of the dust collection component according to the concentration value.

[0078] Specifically, when the air quality is poor, the dust collecting component is promptly turned on or the power of the dust collecting component is increased; when the air quality is good, the dust collecting component is promptly turned off or the power of the dust collecting component is reduced.

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

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

[0081] The second aspect of the present invention provides a control method for an air purification device, the air purification device comprising a base, a dust collecting component and a discharge component, the dust collecting component being arranged on the base, and the discharge component being rotatably connected to the base, the control method for the air purification device comprising: obtaining 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 device is used to treat pollutants in the air to achieve the effect of reducing the content of pollutants in the air. The air purification device includes a base and a dust collection component, and the base is used to position, support and protect the dust collection component.

[0083] The dust collecting component includes a dust collecting surface, which is arranged in a base, and the base avoids the dust collecting surface so that the dust collecting surface can be exposed to the air. After being powered on, the dust collecting component accumulates ions inside, and an electric field can be generated under the action of the accumulated ions. The electric field forms an electric field area on the front side of the dust collecting surface. The pollutants in the electric field area will be polarized, and the polarized pollutants will move toward the dust collecting surface under the action of Coulomb force until the pollutants are adsorbed on the dust collecting surface. Under the adsorption effect, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect.

[0084] On this basis, the air purification device also includes a discharge component, the discharge end of the discharge component and the area facing the dust collecting surface release ions, and the released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collecting component, and the other is connected to the discharge component, so that the polarity of the ions accumulated in the dust collecting component and the ions released by the discharge component are opposite.

[0085] The ions released by the discharge component will attach to the pollutants in the electric field area, so that the pollutants carry an opposite charge to the dust collecting component, thereby increasing the adsorption force of the dust collecting component on the pollutants on the basis of the original Coulomb force, and accelerating the pollutants to move toward the dust collecting surface, thereby improving the adsorption capacity of the dust collecting component and making up for the shortcomings of electric field adsorption.

[0086] The discharge component is rotatably connected to the base, and the direction of the discharge component can be adjusted by controlling the rotation of the discharge component, and the transmission direction of the released ions can be adjusted accordingly. Specifically, the discharge component is rotatably connected to the base through a bracket, and the direction of the third discharge needle on the bracket can be adjusted accordingly by controlling the rotation of the bracket.

[0087] On this basis, the control method of the air purification device is as follows: after the air purification device is turned on based on the purification instruction, the concentration value of pollutants in the air is obtained through the sensor. After the concentration value is obtained, the discharge component is controlled to rotate according to the concentration value so that the discharge component faces the target direction or swings at the target frequency.

[0088] By limiting the above control steps, the discharge component can rotate or swing according to the density of the pollutants to ensure that the working state of the discharge component can meet the cleaning requirements corresponding to the current concentration value of the pollutants, so as to improve the air purification equipment's ability to capture pollutants. This solves the technical problems of the Coulomb force on pollutants that does not meet the standards, the pollutant capture capacity is insufficient, and the purification effect is poor in the related technologies. This achieves the technical effect of optimizing the control process of the air purification equipment, improving the purification capacity of the air purification equipment, and improving 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 a target direction according to the concentration value; and controlling the rotation of the discharge component to direct the discharge component toward the target direction.

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

[0091] By limiting the above control steps, the dust collecting component can adjust its orientation according to the concentration value of the pollutants, thereby automatically adjusting the coverage area of ​​the ions and the overlap of the electric field area, and adjusting the incident direction of the ions, so as to automatically distribute the enhancement effect of the discharge component on the dust collecting component and the sterilization effect on the pollutants in the air by adjusting the difficulty of the ions being captured by the dust collecting component. This achieves the technical effect of improving the automation and intelligence of the air purification equipment and improving the air purification capacity of the air purification equipment.

[0092] In some technical schemes of the present invention, optionally, the dust collecting component includes a dust collecting surface, which can generate an electric field when powered on, and the dust collecting surface is used to collect pollutants in the air through the electric field; the angle between the target direction and the dust collecting 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 bracket and a third discharge needle. The emission end of the third discharge needle is oriented in the third direction, and the angle between the third direction and the dust collecting surface is the first angle; the range of 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 through the bracket; the bracket can adjust the first angle by rotation. By arranging the third discharge needle on a rotatable bracket, the direction of the third discharge needle can be adjusted according to the actual purification needs.

[0094] Specifically, when the pollutant content in the air is high, the first angle is reduced by rotating the bracket to increase the enhancement of the adsorption capacity of the dust collecting component by the third discharge. Correspondingly, when the pollutant content in the air is low, the first angle is increased by rotating the bracket to enhance the sterilization effect of the third discharge on the pollutants in the air, so that the strengthening function and sterilization function of the third discharge needle can be adjusted according to actual needs. Or the overlapping area between the release area of ​​ions and the electric field area can be expanded by controlling the swing of the bracket, thereby increasing the possibility of pollutants in the electric field area being attached by ions. Thereby achieving the technical effect of improving the intelligence level of air purification equipment and improving the practicality of air purification equipment.

[0095] In some technical solutions of the present invention, optionally, the step of controlling the discharge component to rotate 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] In this technical solution, the steps of controlling the rotation of the discharge component according to the concentration value are refined. Specifically, after obtaining the concentration value, the concentration value is compared with the first threshold value. If the concentration value is greater than or equal to the first threshold value, the discharge component is controlled to swing. During the swinging process, the angle between the third discharge needle on the discharge component and the dust collecting surface ranges from 0° to 90°, thereby increasing the overlapping area of ​​the ion coverage area and the electric field area by swinging the discharge component, and reducing the difficulty of ions attaching to pollutants in the discharge area. Correspondingly, when the concentration value is less than the first threshold value, the discharge component is controlled to stop swinging to avoid the swinging discharge needle affecting the sterilization effect of the discharge component on pollutants, and to reduce unnecessary energy consumption. Thereby achieving the technical effect of improving the intelligence level of air purification equipment and improving the practicality of air purification equipment.

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

[0098] In this technical solution, the steps of controlling the swing of the discharge component are refined. Specifically, when the concentration value is greater than the first threshold, the target frequency is first determined according to the concentration value, and then the discharge component is controlled to swing according to the target frequency. This ensures that the swing frequency of the discharge component matches the current air quality and that the air purification device can meet the air purification requirements. This achieves the technical effect of improving the intelligence of the air purification device and improving the practicality of the air purification device.

[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 greater the concentration value, the greater the swing frequency of the discharge component, and the smaller the concentration value, the smaller the swing frequency of the discharge component. When the concentration value is large, by controlling the high-frequency swing of the discharge component, the pollutants entering the electric field area can be attached in time through ions, so as to speed up the rate at which the pollutants are captured by the dust collecting surface. When the concentration value is small, by controlling the low-frequency swing of the discharge component, energy consumption can be reduced while meeting the pollutant attachment requirements. This achieves the technical effect of improving the intelligence level of air purification equipment and improving the practicality of air purification equipment.

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

[0102] In this technical solution, after obtaining the concentration value, the concentration value and the second threshold value are compared. If the concentration value is greater than or equal to the second threshold value, it means that the pollutant content in the air is high and needs to be purified. Then the dust collecting component and the discharge component are controlled to be turned on to turn on the purification mode of the air purification device. Correspondingly, if the concentration value is less than the second threshold value, it means that the pollutant content in the air is low and meets the user's demand for air cleanliness. Then the dust collecting component and the discharge component are controlled to be turned off to exit the purification mode of the air purification device. Among them, the second threshold value is less than or equal to the first threshold value, and the specific second threshold value can be selected as 75μg / m2.

[0103] By limiting the above control steps, the automatic start and stop of the air purification mode is realized, so that the concentration value of pollutants in the current environment is maintained below the second threshold value, thereby achieving the technical effect of improving the automation and intelligence of air purification equipment, improving the purification capacity of air purification equipment, and reducing the energy consumption of air purification equipment.

[0104] The third aspect of the present invention provides a control device for an air purification device, the air purification device includes a base, a dust collecting component and a discharge component, the dust collecting component is arranged 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, used to obtain the concentration value of pollutants in the air; and a control module, used to control the rotation of the discharge component according to the concentration value.

[0105] In this technical solution, the air purification device is used to treat pollutants in the air to achieve the effect of reducing the content of pollutants in the air. The air purification device includes a base and a dust collection component, and the base is used to position, support and protect the dust collection component.

[0106] The dust collecting component includes a dust collecting surface, which is arranged in a base, and the base avoids the dust collecting surface so that the dust collecting surface can be exposed to the air. After being powered on, the dust collecting component accumulates ions inside, and an electric field can be generated under the action of the accumulated ions. The electric field forms an electric field area on the front side of the dust collecting surface. The pollutants in the electric field area will be polarized, and the polarized pollutants will move toward the dust collecting surface under the action of Coulomb force until the pollutants are adsorbed on the dust collecting surface. Under the adsorption effect, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect.

[0107] On this basis, the air purification device also includes a discharge component, the discharge end of the discharge component and the area facing the dust collecting surface release ions, and the released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collecting component, and the other is connected to the discharge component, so that the polarity of the ions accumulated in the dust collecting component and the ions released by the discharge component are opposite.

[0108] The ions released by the discharge component will attach to the pollutants in the electric field area, so that the pollutants carry an opposite charge to the dust collecting component, thereby increasing the adsorption force of the dust collecting component on the pollutants on the basis of the original Coulomb force, and accelerating the pollutants to move toward the dust collecting surface, thereby improving the adsorption capacity of the dust collecting component and making up for the shortcomings of electric field adsorption.

[0109] The discharge component is rotatably connected to the base, and the direction of the discharge component can be adjusted by controlling the rotation of the discharge component, and the transmission direction of the released ions can be adjusted accordingly. Specifically, the discharge component is rotatably connected to the base through a bracket, and the direction of the third discharge needle on the bracket can be adjusted accordingly by controlling the rotation of the bracket.

[0110] On this basis, the control device of the air purification device includes an acquisition module and a control module. After the air purification device is turned on based on the purification instruction, the acquisition module obtains the concentration value of pollutants in the air through the sensor. After obtaining the concentration value, the control module controls the rotation of the discharge component according to the concentration value, so that the discharge component faces the target direction, or makes the discharge component swing according to the target frequency.

[0111] By limiting the above control device, the discharge component can rotate or swing according to the density of the pollutant to ensure that the working state of the discharge component can meet the cleaning requirements corresponding to the current concentration value of the pollutant, so as to improve the air purification equipment's ability to capture pollutants. This solves the technical problems of the Coulomb force on pollutants that does not meet the standards, the pollutant capture capacity is insufficient, and the purification effect is poor in the related technology. This achieves the technical effect of optimizing the control process of the air purification equipment, improving the purification capacity of the air purification equipment, and improving the user experience.

[0112] The fourth aspect of the present invention provides a control device for an air purification device, the control device for the air purification device comprising: a memory, in which a program or instruction is stored; a processor, which executes the program or instruction stored in the memory to implement the steps of a control method for the air purification device as in any of the above technical solutions.

After the processor in the control device for air purification equipment executes the program and instructions stored in the memory, the steps of the control method for air purification equipment in any of the above technical solutions can be implemented. Therefore, the control device for air purification equipment has the advantages of the control method for air purification equipment in any of the above technical solutions, and can achieve the technical effects that can be achieved by the control method for air purification equipment in any of the above technical solutions. To avoid repetition, it will not be repeated here.

[0114] A fifth aspect of the present invention provides a readable storage medium having a program or instruction stored thereon, which, when executed by a processor, implements the steps of a method for controlling an air purification device as in any of the above technical solutions.

[0115] In this technical solution, a readable storage medium is defined.

To avoid repetition, it will not be repeated here.

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

[0117] In this technical solution, an air purification device is defined, which has the advantages of the control device of the air purification device in any of the above technical solutions, or has the advantages of the readable storage medium in the above technical solution.

DETAILED DESCRIPTION

[0149] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0150] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

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

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

[0153] The present application defines an air purification device 100 , which is used to process pollutants 200 in the air to reduce the content of the pollutants 200 in the air. The air purification device 100 includes a dust collecting component 120 .

[0154] The dust collecting component 120 includes a dust collecting surface 122, which can be exposed to the air. After being powered on, the dust collecting component 120 accumulates ions inside, and an electric field can be generated under the action of the accumulated ions. The electric field forms an electric field area in front of the dust collecting surface 122, and the pollutants 200 in the electric field area will be polarized. The polarized pollutants 200 move toward the dust collecting surface 122 under the action of the Coulomb force until the pollutants 200 are adsorbed on the dust collecting surface 122. Under this adsorption effect, the concentration of the pollutants 200 in the electric field area is reduced, and under the action of the concentration difference, the pollutants 200 outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of the pollutants 200 in the entire environment to achieve an air purification effect.

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

[0156] The ions released by the discharge component 144 will adhere to the pollutants 200 in the electric field area, so that the pollutants 200 carry the opposite charge to the dust collecting component 120, thereby increasing the adsorption force of the dust collecting component 120 on the pollutants 200 on the basis of the original Coulomb force, so that the pollutants 200 are accelerated to move toward the dust collecting surface 122, thereby improving the adsorption capacity of the dust collecting component 120, making up for the deficiencies in electric field adsorption, and solving the technical problems of the Coulomb force on the pollutants 200, the insufficient capture capacity of the pollutants 200, and the poor purification effect existing in the related technology. Then, the technical effect of optimizing the structure of the air purification device 100, improving the purification capacity of the air purification device 100, and improving the user experience is achieved. At the same time, the ions released by the discharge component 144 can also play a bactericidal role to reduce the content of toxic substances in the air and protect the health of users.

[0157] On this basis, the dust collecting assembly 120 proposed in the present application collects pollutants 200 through an electric field, and the collected pollutants 200 adhere to the dust collecting surface 122. After use, the pollutants 200 can be removed by washing or wiping the dust collecting surface 122, eliminating the need for frequent replacement of filter materials, thereby reducing the use cost of the air purification device 100. At the same time, the noise generated by the dust collecting assembly 120 when powered on is relatively small, which can further enhance the user experience.

[0158] Specifically, the dust collection component 120 proposed in the present application can actively absorb pollutants 200 in the air with the help of the electric field generated by itself, without the need for circulating airflow to achieve air purification function, thereby eliminating the space for arranging the air duct 1522 and the fan, and providing convenient conditions for the miniaturization and lightweight design of the air purification equipment 100.

[0159] Specifically, Fig.24 and Fig.25 As shown, the dust collecting assembly 120 and the discharge component 144 can be a split structure, the dust collecting assembly 120 and the discharge component 144 are independently powered, and the positions of the dust collecting assembly 120 and the discharge component 144 can be freely adjusted according to the scene requirements. During use, the dust collecting assembly 120 is arranged first, and then the discharge component 144 is placed in the electric field area generated by the dust collecting assembly 120 to ensure that the discharge component 144 can effectively cooperate with the dust collecting assembly 120 to absorb pollutants 200 in the air.

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

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

[0162] Visible particles: particles with a diameter of 10 microns or less, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0163] Fine particulate matter: Particles with a diameter of less than or equal to 2.5 microns, which cannot be seen by the naked eye but have a greater impact on human health, such as automobile exhaust and factory waste gas.

[0164] Ultrafine particles: particles with a diameter of 0.1 microns or less, which cannot be seen by 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 an emission end, the connection end is used to connect the other of the positive electrode and the negative electrode, and the emission end is used for discharging.

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

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

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

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

[0170] In this technical solution, the dust collecting component 120 and the discharge component 144 can be powered independently, so as to realize the split design of the dust collecting component 120 and the discharge component 144. Specifically, the dust collecting component 120 is connected to the power supply through the first voltage regulator 170. Under the voltage regulation of the first voltage regulator 170, the potential of the dust collecting component 120 is higher than the ground potential, so that a positive voltage is formed between the dust collecting component 120 and the zero pole. Correspondingly, the discharge component 144 is connected to the power supply through the 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, so that a negative voltage is formed between the discharge component 144 and the zero pole. The discharge component 144 carrying a negative voltage can release negative ions into the air, so that the pollutants 200 in the air are negatively charged. After the pollutants 200 carry negative electricity, they will move toward the dust collecting component 120 carrying positive electricity, and finally be captured by the dust collecting component 120, thereby removing the pollutants 200 in the air.

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

[0172] Figure 7 , Figure 8 and Fig. 9 In the figure, arrow a shows the direction of the dust collecting surface.

[0173] In this embodiment, the discharge needle includes a first discharge needle 1442, which is located in front of the dust collecting surface 122, and the emission end of the first discharge needle 1442 is oriented in a first direction, which is parallel to the dust collecting surface 122. When the dust collecting surface 122 is a plane, the first discharge needle 1442 is perpendicular to the normal direction of the dust collecting surface 122. After power is turned on, the first discharge needle 1442 releases ions along the first direction, and after moving to the electric field area, the ions adhere to the particles to charge the particles.

[0174] By setting a first discharge needle 1442 parallel to the dust collecting surface 122, the deviation between the movement trajectory of the released ions and the electric field area generated by the dust collecting component 120 can be reduced, thereby increasing the possibility of pollutants 200 in the electric field area being attached by the ions, thereby achieving the technical effect of improving the adsorption capacity of the air purification equipment 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 emission end of the second discharge needle 1444 is oriented in a second direction, and the second direction is perpendicular to the dust collecting surface 122 .

[0176] In this embodiment, the discharge needle includes a second discharge needle 1444, which is located in front of the dust collecting surface 122, and the emission end of the second discharge needle 1444 is oriented in the second direction, which is perpendicular to the dust collecting surface 122. When the dust collecting surface 122 is a plane, the second discharge needle 1444 is parallel to the normal direction of the dust collecting surface 122. After power is turned on, the second discharge needle 1444 releases ions along the second direction, and after moving to the electric field area, the ions adhere to the particles to charge the particles.

[0177] By setting a second discharge needle 1444 perpendicular to the dust collecting surface 122, there can be a certain deviation between the movement trajectory of the released ions and the electric field area generated by the dust collecting component 120, so that some of the released ions can enter the electric field area and eventually be captured by the dust collecting component 120, while the other part of the ions can move to the area outside the electric field area and sterilize the pollutants 200 outside the electric field area. Thus, on the basis of maintaining the improvement of the adsorption capacity of the dust collecting component 120 for pollutants 200, the sterilization ability of the discharge component 144 for pollutants 200 in the air is strengthened, so that the air purification device 100 takes into account both the collection of pollutants 200 and sterilization. Then, the technical effect of broadening the function of the air purification device 100 and improving the practicality and reliability of the air purification device 100 is achieved.

[0178] like Fig. 9 As shown, in some embodiments of the present invention, optionally, the discharge needle includes: a third discharge needle 1446, the emission end of the third discharge needle 1446 is directed in a third direction, and the angle between the third direction and the dust collecting 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 collecting surface 122, and the emission end of the third discharge needle 1446 is oriented in the third direction, and the angle between the third direction and the dust collecting surface 122 is between 0° and 90°. After power is turned on, the third discharge needle 1446 releases ions along the third direction, and after the ions move to the electric field area, they are attached to the particles to charge the particles.

[0180] When the dust collecting surface 122 is a plane or an outwardly extended smooth curved surface, the formed electric field area is fan-shaped. By setting the third discharge needle 1446, the movement trajectory of the ions in the electric field area can be extended by constructing the first angle, thereby increasing the possibility of the ions adhering to the pollutants 200, thereby 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 the bracket 142; the bracket 142 can adjust the first angle by rotating.

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

[0183] By setting the third discharge needle 1446 on the rotatable bracket 142, the orientation of the third discharge needle 1446 can be adjusted according to the actual purification needs. Specifically, when the content of pollutants 200 in the air is high, the first angle is reduced by rotating the bracket 142 to increase the enhancement of the adsorption capacity of the dust collecting assembly 120 by the third discharge needle 1446. Correspondingly, when the content of pollutants 200 in the air is low, the first angle is increased by rotating the bracket 142 to enhance the sterilization effect of the third discharge needle 1446 on the pollutants 200 in the air, so that the strengthening function and sterilization function of the third discharge needle 1446 can be adjusted according to actual needs. Or the overlapping area between the release area of ​​ions and the electric field area can be expanded by controlling the swing of the bracket 142, thereby increasing the possibility of the pollutants 200 in the electric field area being attached by ions. Then, the technical effect of improving the intelligence of the air purification device 100 and improving the practicality of the air purification device 100 is achieved.

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

[0185] In this embodiment, the discharge component 144 further includes a driving component 146, which is fixed on the base 110, and the driving end of the driving component 146 is connected to the bracket 142. After the driving component 146 is powered on, it can drive the bracket 142 to rotate to adjust the size of the first angle. By providing the driving component 146, the bracket 142 can be driven to rotate by the driving component 146 to automatically adjust the direction 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 degree of automation of the air purification device 100.

[0186] Specifically, the driving component 146 is a motor, the output shaft of the motor is connected to the rotating shaft of the third bracket 142, and 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, there are multiple discharge needles; the multiple discharge needles are arranged side by side on the bracket 142.

[0188] In this embodiment, a plurality of discharge needles are arranged on the bracket 142, and the plurality of discharge needles are arranged side by side on the bracket 142. By arranging a plurality of discharge needles side by side on the bracket 142, the coverage 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 in the electric field area being attached by the ions, and achieving the technical effect of improving the adsorption capacity of the dust collecting assembly 120 for the pollutants 200.

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

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

[0191] At the same time, the base 110 has a larger contact surface and a lower center of gravity, which can reduce the probability of the dust collecting component 120 and the discharge component 144 tilting or falling 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 also includes: a bracket 142, which is arranged in the cavity 117; a discharge component 144, which is arranged in the bracket 142, and the discharge port 116 is arranged opposite to the discharge component 144.

[0193] In this embodiment, the base 110 is also provided with a discharge port 116, which is connected to a cavity 117 in the base 110. On this basis, the air purification device 100 further includes a discharge component 144, the discharge end of the discharge component 144 is opposite to the discharge port 116, and the discharge component 144 can discharge to the outside of the base 110 through the discharge port 116 after being energized. The bracket 142 is disposed in the cavity 117 in the base 110 and is connected to the base 110. The bracket 142 is used to position and support the discharge component 144. After the discharge component 144 is energized, it 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 a slot on the inner wall of the cavity 117, or the discharge component 144 can be fixed to the inner wall of the cavity 117 by means of screws or other connectors to ensure that the discharge component 144 can be accurately fixed in a predetermined working position.

[0196] In some embodiments of the present invention, optionally, the air purification device 100 also includes: a power supply component, which is arranged on the base 110, and the power supply component includes a positive electrode and a negative electrode, the positive electrode is connected to one of the dust collecting component 120 and the discharge component 144, and the negative electrode is connected to the other of the dust collecting component 120 and the discharge component 144.

[0197] Specifically, the power supply component is provided in the controller 160 .

[0198] In this embodiment, the air purification device 100 also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collecting component 120, and the other is connected to the discharge component 144, so that the ions accumulated inside the dust collecting component 120 and the ions released by the discharge component 144 have opposite polarities. The ions released by the discharge component 144 will adhere to the pollutants 200 in the electric field area, so that the pollutants 200 carry the opposite charge to the dust collecting component 120, thereby increasing the adsorption force of the dust collecting component 120 on the pollutants 200 on the basis of the original Coulomb force, so that the pollutants 200 are accelerated to move toward the dust collecting surface 122, thereby improving the adsorption capacity of the dust collecting component 120, making up for the shortcomings of the electric field adsorption, and solving the technical problems of the Coulomb force on the pollutants 200 not meeting the standards, the insufficient capture capacity of the pollutants 200, and the poor purification effect in the related technology. Then, the technical effect of optimizing the structure of the air purification device 100, improving the purification capacity of the air purification device 100, and improving the user experience is achieved.

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

[0200] In this embodiment, the structure of the dust collecting assembly 120 is refined. Specifically, the dust collecting assembly 120 includes a guard plate 124 and a conductive component 126. Specifically, the number of the guard plates 124 is multiple, and the multiple guard plates 124 are stacked along the thickness direction of the base 110, and the two adjacent guard plates 124 are spaced apart to form a gap between the two adjacent guard plates 124. The conductive component 126 is arranged in the gap between the two adjacent guard plates 124, and the conductive component 126 can generate an electric field after being energized. On the multiple guard plates 124, the surface facing away from the conductive component 126 is the dust collecting surface 122. For example, when the number of the guard plates 124 is two, the outer side surfaces of the two guard plates 124 form two dust collecting surfaces 122. When the number of the guard plates 124 is three, both sides of the middle guard plate 124 face the conductive component 126 and no dust collecting surface 122 is formed. The outer side surfaces of the guard plates 124 on both sides form two dust collecting surfaces 122, that is, increasing the number of guard plates 124 will not increase the number of dust collecting surfaces 122.

[0201] Specifically, the air purification device 100 also includes a power supply component, which is arranged in the base 110. The power supply component includes a positive electrode and a negative electrode. The conductive component 126 is connected to the positive electrode so that positive DC high voltage is passed to the conductive component 126 through the power supply component. After the conductive component 126 is passed with positive DC high voltage, a large amount of negative ions can be stored in the conductive component 126, thereby forming an electric field. After the pollutant 200 moves to the electric field area, it is polarized under the action of the electric field, so that it is adsorbed onto the dust collecting surface 122. In the process of approaching the dust collecting surface 122, the closer to the dust collecting surface 122, the stronger the adsorption force, so the pollutant 200 has a process of accelerating movement toward the dust collecting surface 122.

[0202] On this basis, the surface of the guard plate 124 facing the conductive component 126 is covered with a first conductive layer, and the first conductive layer can enhance the electric field to strengthen the adsorption capacity of the dust collecting 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, which has the advantages of high strength, strong corrosion resistance, and insulation, and can provide long-term and effective protection for the internal conductive components 126, thereby improving the reliability of the dust collecting assembly 120 and reducing the failure rate of the dust collecting assembly 120. At the same time, the insulation property can prevent the dust collecting assembly 120 from having leakage problems, thereby improving the safety of the dust collecting assembly 120.

[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 outside of the conductive wire. By setting the second conductive layer, the conductive performance of the conductive component 126 can be further improved, thereby increasing the strength of the electric field to enhance the adsorption capacity of the dust collecting component 120 for pollutants 200.

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

[0206] Specifically, a conductive foam is disposed between two adjacent guard plates 124 , and the conductive foam cooperates with the conductive thread and the second conductive layer to fill the gap between the two adjacent guard 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 air flow outlet 118 and a second air flow outlet 119, the first air flow outlet 118 is connected to the second air flow outlet 119 through the cavity 117, and also includes: an ion wind component 150, which is arranged in the cavity 117.

[0208] In this embodiment, the base 110 is further provided with a first air flow opening 118 and a second air flow opening 119 , and the first air flow opening 118 is connected with the second air flow opening 119 through the cavity 117 , that is, the first air flow opening 118 , the cavity 117 and the second air flow opening 119 are combined into an air flow passage.

[0209] On this basis, the air purification device 100 also includes an ion wind component 150, which is arranged in the cavity 117. After the ion wind component 150 is powered on, ions that move in a directional manner are generated inside the component, and the ions can drive the nearby gas flow during the directional movement, thereby generating a corresponding directional flow of airflow. On the one hand, the airflow can accelerate the flow of air near the air purification device 100, thereby cooperating with the dust collection component 120 and the discharge component 144 to improve the air purification capacity. On the other hand, the directional flow of ions can sterilize the pollutants 200 in the driven airflow to reduce the content of toxic substances in the air and protect the health of users.

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

[0211] In this embodiment, the structure of the ion wind component 150 is refined, and the ion wind component 150 includes a frame 152, an ion emitting component 154, and an ion receiving component 156. The frame 152 is arranged in the cavity 117, and the frame 152 is connected to the base 110. A through air duct 1522 is arranged in the frame 152, and the outlet end of the air duct 1522 is opposite to the first air flow outlet 118. The ion emitting component 154 and the ion receiving component 156 are arranged in the frame 152, and the frame 152 can provide support and protection for the ion emitting component 154 and the ion receiving component 156. Among them, the ion receiving component 156 is arranged at a position close to the outlet end of the air duct 1522, and the ion receiving component 156 is arranged at a position close to 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 electrode of the power supply component, and the other is connected to the negative electrode of the power supply component. After power is turned on, the ion emitting component 154 releases ions, and the released ions are captured by the ion receiving component 156, thereby forming directional flow of ions and directional flow of air. 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 cycle in conjunction with the second airflow port 119.

[0213] like Figure 1 As shown, in some embodiments of the present invention, optionally, the air purification device 100 also includes: a controller 160, which is disposed on the base 110 and is electrically connected to the dust collecting component 120 and the discharge component 144; a sensor, which is disposed on the base 110 and is used to detect the concentration value of the pollutant 200 in the air.

[0214] In this embodiment, the air purification device 100 further includes a controller 160 and a sensor, both of which are arranged on the base 110, the controller 160 is electrically connected to the dust collecting 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 the pollutant 200 in the air from the sensor, and then the controller 160 controls the start and stop and power of the dust collecting assembly 120 according to the concentration value.

[0215] Specifically, when the air quality is poor, the dust collecting component 120 is promptly turned on or the power of the dust collecting component 120 is increased; when the air quality is good, the dust collecting component 120 is promptly turned off or the power of the dust collecting component 120 is reduced.

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

[0217] It can be seen that by setting up the controller 160 and the sensor, the working state of the air purification device 100 can be adjusted 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 collecting surface 122 is a plane, or the dust collecting surface 122 is a smooth curved surface.

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

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

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

[0222] In this embodiment, the discharge component 144 includes a first discharge component, which is located in front of the dust collecting surface 122, and the emission end of the first discharge component is oriented in a first direction, which is parallel to the dust collecting surface 122. When the dust collecting surface 122 is a plane, the first discharge component is perpendicular to the normal direction of the dust collecting surface 122. After power is turned on, the first discharge component releases ions along the first direction, and after the ions move to the electric field area, they adhere to the particles to charge the particles.

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

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

[0225] In this embodiment, the discharge component 144 includes a second discharge component, which is located in front of the dust collecting surface 122, and the emission end of the second discharge component is oriented in the second direction, which is perpendicular to the dust collecting surface 122. When the dust collecting surface 122 is a plane, the second discharge component is parallel to the normal direction of the dust collecting surface 122. After power is turned on, the second discharge component releases ions along the second direction, and after moving to the electric field area, the ions are attached to the particles to charge the particles.

[0226] By setting a second discharge component perpendicular to the dust collecting surface 122, there can be a certain deviation between the movement trajectory of the released ions and the electric field area generated by the dust collecting component 120, so that some of the released ions can enter the electric field area and eventually be captured by the dust collecting component 120, while the other part of the ions can move to the area outside the electric field area and sterilize the pollutants 200 outside the electric field area. Thus, on the basis of maintaining the improvement of the adsorption capacity of the dust collecting component 120 for pollutants 200, the sterilization ability of the discharge component 144 for pollutants 200 in the air is strengthened, so that the air purification device 100 takes into account both the collection of pollutants 200 and sterilization. Then, the technical effect of broadening the function of the air purification device 100 and improving the practicality and reliability of the air purification device 100 is achieved.

[0227] In some embodiments of the present invention, optionally, the discharge component 144 includes: a third discharge component, the emission end of the third discharge component is directed in a third direction, and the angle between the third direction and the dust collecting 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, which is located in front of the dust collecting surface 122, and the emission end of the third discharge component is oriented in the third direction, and the angle between the third direction and the dust collecting surface 122 is between 0° and 90°. After power is turned on, the third discharge component releases ions along the third direction, and after the ions move to the electric field area, they adhere to the particles to charge the particles.

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

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

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

[0232] By setting the third discharge component on the rotatable bracket 142, the orientation of the third discharge component can be adjusted according to the actual purification needs. Specifically, when the content of pollutants 200 in the air is high, the first angle is reduced by rotating the bracket 142 to increase the enhancement of the adsorption capacity of the dust collecting assembly 120 by the third discharge component. Correspondingly, when the content of pollutants 200 in the air is low, the first angle is increased by rotating the bracket 142 to enhance the sterilization effect of the third discharge component on the pollutants 200 in the air, so that the strengthening function and sterilization function of the third discharge component can be adjusted according to actual needs. Or the overlapping area between the release area of ​​ions and the electric field area can be expanded by controlling the swing of the bracket 142, thereby increasing the possibility of pollutants 200 in the electric field area being attached by ions. Thereby achieving the technical effect of improving the intelligence of the air purification device 100 and improving the practicality of the air purification device 100.

[0233] In some embodiments of the present invention, optionally, the air purification device 100 further includes: a driving component 146 connected to the bracket 142 and used for driving the bracket 142 to rotate.

[0234] In this embodiment, the driving component 146 is fixed on the base 110, and the driving end of the driving component 146 is connected to the bracket 142. After the driving component 146 is powered on, it can drive the bracket 142 to rotate to adjust the size of the first angle. By setting the driving component 146, the bracket 142 can be driven to rotate by the driving component 146 to automatically adjust the direction of the third discharge component, eliminating the need for the user to manually adjust the bracket 142. Thereby achieving the technical effect of improving the degree of automation of the air purification device 100.

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

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

[0237] Step 1602, obtaining the concentration value of pollutants in the air;

[0238] Step 1604, controlling the rotation of the discharge component according to the concentration value.

[0239] In this embodiment, the air purification device is used to process pollutants in the air to achieve the effect of reducing the content of pollutants in the air. The air purification device includes a base and a dust collection component, and the base is used to position, support and protect the dust collection component.

[0240] The dust collecting component includes a dust collecting surface, which is arranged in a base, and the base avoids the dust collecting surface so that the dust collecting surface can be exposed to the air. After being powered on, the dust collecting component accumulates ions inside, and an electric field can be generated under the action of the accumulated ions. The electric field forms an electric field area on the front side of the dust collecting surface. The pollutants in the electric field area will be polarized, and the polarized pollutants will move toward the dust collecting surface under the action of Coulomb force until the pollutants are adsorbed on the dust collecting surface. Under the adsorption effect, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect.

[0241] On this basis, the air purification device also includes a discharge component, the discharge end of the discharge component and the area facing the dust collecting surface release ions, and the released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collecting component, and the other is connected to the discharge component, so that the polarity of the ions accumulated in the dust collecting component and the ions released by the discharge component are opposite.

[0242] The ions released by the discharge component will attach to the pollutants in the electric field area, so that the pollutants carry an opposite charge to the dust collecting component, thereby increasing the adsorption force of the dust collecting component on the pollutants on the basis of the original Coulomb force, and accelerating the pollutants to move toward the dust collecting surface, thereby improving the adsorption capacity of the dust collecting component and making up for the shortcomings of electric field adsorption.

[0243] The discharge component is rotatably connected to the base, and the direction of the discharge component can be adjusted by controlling the rotation of the discharge component, and the transmission direction of the released ions can be adjusted accordingly. Specifically, the discharge component is rotatably connected to the base through a bracket, and the direction of the third discharge needle on the bracket can be adjusted accordingly by controlling the rotation of the bracket.

[0244] On this basis, the control method of the air purification device is as follows: after the air purification device is turned on based on the purification instruction, the concentration value of pollutants in the air is obtained through the sensor. After the concentration value is obtained, the discharge component is controlled to rotate according to the concentration value so that the discharge component faces the target direction or swings at the target frequency.

[0245] By limiting the above control steps, the discharge component can rotate or swing according to the density of the pollutants to ensure that the working state of the discharge component can meet the cleaning requirements corresponding to the current concentration value of the pollutants, so as to improve the air purification equipment's ability to capture pollutants. This solves the technical problems of the Coulomb force on pollutants that does not meet the standards, the pollutant capture capacity is insufficient, and the purification effect is poor in the related technologies. This achieves the technical effect of optimizing the control process of the air purification equipment, improving the purification capacity of the air purification equipment, and improving the user experience.

[0246] like Fig.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, determining the target direction according to the concentration value;

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

[0249] In this embodiment, the step of controlling the discharge component to rotate according to the concentration value is refined. Specifically, after the concentration value is obtained, the corresponding target direction is determined according to the concentration value. After the target direction is determined, the discharge component is controlled to rotate so that the third discharge needle on the discharge component faces the target direction.

[0250] By limiting the above control steps, the dust collecting component can adjust its orientation according to the concentration value of the pollutants, thereby automatically adjusting the coverage area of ​​the ions and the overlap of the electric field area, and adjusting the incident direction of the ions, so as to automatically distribute the enhancement effect of the discharge component on the dust collecting component and the sterilization effect on the pollutants in the air by adjusting the difficulty of the ions being captured by the dust collecting component. This achieves the technical effect of improving the automation and intelligence of the air purification equipment and improving the air purification capacity of the air purification equipment.

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

[0252] In this embodiment, the discharge component includes a bracket and a third discharge needle. The emission end of the third discharge needle is oriented in the third direction, and the angle between the third direction and the dust collecting surface is the first angle; the range of 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 through the bracket; the bracket can adjust the first angle by rotation. By arranging the third discharge needle on a rotatable bracket, the direction of the third discharge needle can be adjusted according to the actual purification needs.

[0253] Specifically, when the pollutant content in the air is high, the first angle is reduced by rotating the bracket to increase the enhancement of the adsorption capacity of the dust collecting component by the third discharge. Correspondingly, when the pollutant content in the air is low, the first angle is increased by rotating the bracket to enhance the sterilization effect of the third discharge on the pollutants in the air, so that the strengthening function and sterilization function of the third discharge needle can be adjusted according to actual needs. Or the overlapping area between the release area of ​​ions and the electric field area can be expanded by controlling the swing of the bracket, thereby increasing the possibility of pollutants in the electric field area being attached by ions. Thereby achieving the technical effect of improving the intelligence level of air purification equipment and improving the practicality of 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 the concentration value being greater than or equal to a first threshold, controlling the discharge component to swing;

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

[0257] In this embodiment, the step of controlling the rotation of the discharge component according to the concentration value is refined. Specifically, after obtaining the concentration value, the concentration value is compared with the first threshold value. If the concentration value is greater than or equal to the first threshold value, the discharge component is controlled to swing. During the swinging process, the angle between the third discharge needle on the discharge component and the dust collecting surface ranges from 0° to 90°, thereby increasing the overlapping area of ​​the ion coverage area and the electric field area by swinging the discharge component, and reducing the difficulty of ions attaching to pollutants in the discharge area. Correspondingly, when the concentration value is less than the first threshold value, the discharge component is controlled to stop swinging to avoid the swinging discharge needle affecting the sterilization effect of the discharge component on pollutants, and to reduce unnecessary energy consumption. Thereby achieving the technical effect of improving the intelligence level of air purification equipment and improving the practicality of air purification equipment.

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

[0259] Step 1802, determining the target frequency according to the concentration value;

[0260] Step 1804, controlling the discharge component to swing according to the target frequency.

[0261] In this embodiment, the step of controlling the discharge component to swing is refined. Specifically, when the concentration value is greater than the first threshold, the target frequency is first determined according to the concentration value, and then the discharge component is controlled to swing according to the target frequency. This ensures that the swing frequency of the discharge component matches the current air quality and that the air purification device can meet the air purification requirements. This achieves the technical effect of improving the intelligence of the air purification device and improving the practicality of the air purification device.

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

[0263] In this embodiment, the target frequency is positively correlated with the concentration value. That is, the greater the concentration value, the greater the swing frequency of the discharge component, and the smaller the concentration value, the smaller the swing frequency of the discharge component. When the concentration value is large, by controlling the high-frequency swing of the discharge component, the pollutants entering the electric field area can be attached in time through the ions to speed up the rate at which the pollutants are captured by the dust collecting surface. When the concentration value is small, by controlling the low-frequency swing of the discharge component, energy consumption can be reduced on the basis of meeting the pollutant attachment requirements. Thereby achieving the technical effect of improving the intelligence level of air purification equipment and improving the practicality of air purification equipment.

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

[0265] Based on the concentration value being greater than or equal to a second threshold, controlling the dust collecting component and the discharge component to turn on;

[0266] Based on the concentration value being less than the second threshold, the dust collecting assembly and the discharge component are controlled to be closed.

[0267] In this embodiment, after obtaining the concentration value, the concentration value and the second threshold value are compared. If the concentration value is greater than or equal to the second threshold value, it means that the pollutant content in the air is high and needs to be purified. Then the dust collecting component and the discharge component are controlled to be turned on to turn on the purification mode of the air purification device. Correspondingly, if the concentration value is less than the second threshold value, it means that the pollutant content in the air is low, which meets the user's demand for air cleanliness. Then the dust collecting component and the discharge component are controlled to be turned off to exit the purification mode of the air purification device. Among them, the second threshold value is less than or equal to the first threshold value, and the specific second threshold value can be selected as 75μg / m2.

[0268] By limiting the above control steps, the automatic start and stop of the air purification mode is realized, so that the concentration value of pollutants in the current environment is maintained below the second threshold value, thereby achieving the technical effect of improving the automation and intelligence of air purification equipment, improving the purification capacity of air purification equipment, and reducing the energy consumption of air purification equipment.

[0269] like Fig.19As shown, in one embodiment of the present application, the control process of the air purification device is as follows:

[0270] Step 1902, start the purification mode;

[0271] Step 1904, detecting the concentration value of the pollutant;

[0272] Step 1906, whether the concentration value is ≥ 75 μg / m2;

[0273] If the judgment result is yes, execute step 1910; if the judgment result is no, execute step 1908;

[0274] Step 1908, the dust collection component does not work;

[0275] Step 1910, the dust collection component starts working;

[0276] Step 1912, controlling the angle between the discharge needle and the dust collecting surface according to the concentration value;

[0277] Step 1914, the discharge needle swings open;

[0278] Step 1916, the discharge needle swings closed;

[0279] Step 1918: Is the concentration value ≥ 75 μg / m 2 ;

[0280] If the judgment result is yes, execute step 1920; if the judgment result is no, execute step 1910;

[0281] Step 1920, the discharge component stops working;

[0282] Step 1922, purification mode is turned off.

[0283] like Fig. 20 As shown, an embodiment of the present invention provides a control device 2000 of an air purification device, the air purification device includes a base, a dust collecting component and a discharge component, the dust collecting component is arranged on the base, the discharge component is rotatably connected to the base, and the control method of the air purification device includes:

[0284] An acquisition module 2002 is used to acquire the concentration value of pollutants in the air;

[0285] The 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 process pollutants in the air to achieve the effect of reducing the content of pollutants in the air. The air purification device includes a base and a dust collection component, and the base is used to position, support and protect the dust collection component.

[0287] The dust collecting component includes a dust collecting surface, which is arranged in a base, and the base avoids the dust collecting surface so that the dust collecting surface can be exposed to the air. After being powered on, the dust collecting component accumulates ions inside, and an electric field can be generated under the action of the accumulated ions. The electric field forms an electric field area on the front side of the dust collecting surface. The pollutants in the electric field area will be polarized, and the polarized pollutants will move toward the dust collecting surface under the action of Coulomb force until the pollutants are adsorbed on the dust collecting surface. Under the adsorption effect, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect.

[0288] On this basis, the air purification device also includes a discharge component, the discharge end of the discharge component and the area facing the dust collecting surface release ions, and the released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collecting component, and the other is connected to the discharge component, so that the polarity of the ions accumulated in the dust collecting component and the ions released by the discharge component are opposite.

[0289] The ions released by the discharge component will attach to the pollutants in the electric field area, so that the pollutants carry an opposite charge to the dust collecting component, thereby increasing the adsorption force of the dust collecting component on the pollutants on the basis of the original Coulomb force, and accelerating the pollutants to move toward the dust collecting surface, thereby improving the adsorption capacity of the dust collecting component and making up for the shortcomings of electric field adsorption.

[0290] The discharge component is rotatably connected to the base, and the direction of the discharge component can be adjusted by controlling the rotation of the discharge component, and the transmission direction of the released ions can be adjusted accordingly. Specifically, the discharge component is rotatably connected to the base through a bracket, and the direction of the third discharge needle on the bracket can be adjusted accordingly by controlling the rotation of the bracket.

[0291] On this basis, the control device 2000 of the air purification device includes an acquisition module 2002 and a control module 2004. After the air purification device is turned on based on the purification instruction, the acquisition module 2002 acquires the concentration value of pollutants in the air through the sensor. After acquiring the concentration value, the control module 2004 controls the rotation of the discharge component according to the concentration value, so that the discharge component faces the target direction, or makes the discharge component swing according to the target frequency.

[0292] By limiting the above control device, the discharge component can rotate or swing according to the density of the pollutant to ensure that the working state of the discharge component can meet the cleaning requirements corresponding to the current concentration value of the pollutant, so as to improve the air purification equipment's ability to capture pollutants. This solves the technical problems of the Coulomb force on pollutants that does not meet the standards, the pollutant capture capacity is insufficient, and the purification effect is poor in the related technology. This achieves the technical effect of optimizing the control process of the air purification equipment, improving the purification capacity of the air purification equipment, and improving the user experience.

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

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

[0298] In this embodiment, an air purification device is defined, which has the advantages of the control device of the air purification device in any of the above embodiments, or has the advantages of the readable storage medium in the above embodiments. Therefore, the technical effects that can be achieved by the control device of the air purification device in any of the above embodiments, or the technical effects that can be achieved by the readable storage medium in the above embodiments can be achieved, and to avoid repetition, they will not be repeated here.

[0299] like Fig. 22 As shown, the figure shows the electric field area generated by the dust collecting component 120 after being energized.

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

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

[0302] Among them, ρ1<ρ2<ρ3<ρ4.

[0303] Arrow d shows the moving direction of the pollutants, V1 is the moving speed of the pollutants in the first sub-region, V2 is the moving speed of the pollutants in the second sub-region, V3 is the moving speed of the pollutants in the third sub-region, and V4 is the moving speed of the pollutants 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 Fig.23 As shown, the air purification equipment provided by the present application includes a dust collecting component, an ion wind component and a discharge component. The dust collecting component includes a guard plate and a conductive component. The guard plate is arranged on both sides of the conductive component. The conductive component is made of a metal conductive material or a non-metallic conductive material. A large amount of negative ions can be stored by utilizing a large specific area.

[0306] Metallic conductive 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 material of the conductive component may also be a combination or compound of metallic conductive materials and / or non-metallic conductive materials. Optionally, the conductive component is a graphene aluminum wire layer.

[0307] The material of the guard plate can be at least one of glass, plastic or rubber. The guard plate can be used as an adsorption structure. By using the Coulomb force between ions, when the adsorbed object approaches the "glass layer" with negative ions, an adsorption effect will be produced. Air pollutants such as PM2.5, dust, and volatile substances can move toward the guard plate in the direction indicated by the arrow M, and then the air pollutants can be adsorbed on the surface of the guard plate.

[0308] The ion wind component and / or the discharge component can transport negative ions to the dust collecting component in the direction indicated by the arrow N, and can emit ion beams in the direction indicated by the arrow O to achieve membrane rupture, sterilization and disinfection through the ion beams.

[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 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 regarded as composed of many point charges. The interaction force between each pair of stationary point charges follows Coulomb's law. Coulomb's law is: the magnitude of the interaction force between two stationary point charges Q1 and Q2 in a vacuum is proportional to the product of Q1 and Q2, and inversely proportional to the square of the distance r between the point charges Q1 and Q2. The direction of the force is along the line connecting them. Charges of the same sign repel each other, and charges of opposite signs attract each other.

[0311] There is no free charge inside an ideal insulating medium, but there is always a small amount of free charge inside an actual dielectric. All kinds of substances can basically be regarded as objects with coincident positive and negative electron centers. Under normal circumstances, the positive and negative bound charges inside a dielectric that is not acted upon by an electric field cancel each other out on average, and do not show electrical properties on a macro scale. Under the action of an external electric field, the local movement of bound charges causes electrical properties to be displayed on a macro scale, and charges appear on the surface and in uneven places inside the dielectric. This phenomenon is called polarization, and the charges that appear are called polarized charges. Conductive components generate electric fields, which generate polarized charges on substances in their electric fields (such as air pollutants, etc.), and then adsorb these substances on the surface of the dust collection component based on the principle that charges of opposite signs attract.

[0312] Furthermore, the dust collecting component is energized to generate an electric field. The particles first move in the space according to the concentration difference, and then move to the electric field area, where they will be adsorbed by the dust collecting component. There will always be a low concentration area near the dust collecting component, allowing the particles to move over.

[0313] When air pollutants move to the electric field area of ​​the dust collecting component, they will be polarized and thus adsorbed onto the dust collecting component, and there will be an accelerated movement process when approaching the dust collecting component.

[0314] The power supply component has a positive electrode and a negative electrode. One of the positive and negative electrodes is connected to the dust collection component, and the other is connected to the discharge component. The discharge component releases electrons into the air, making the air pollutants carry the opposite charge to the dust collection component, accelerating the adsorption to the dust collection component. This improves the purification efficiency. At the same time, the discharge component charges the air pollutants and also has a sterilization effect.

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