Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification device. Background Art

[0002] The air purifier can absorb pollutants in the air through the electric field generated when it is powered on, so as to achieve the purpose of air purification.

[0003] In the related art, air purifiers mostly collect pollutants in the air through built-in air ducts and air cavities, but this solution requires the air to be introduced into the air ducts and air cavities first, which affects the purification efficiency. In addition, the built-in air ducts and air cavities are more difficult to clean dust in the subsequent process, which can easily destroy the user experience. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0005] Therefore, the utility model provides an air purification device.

[0006] In view of this, the utility model provides an air purification device, which includes: a main body; a dust collecting component, which is arranged on the main body, and 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 at least partially exposed. At least part of the exposed dust collecting surface is used to collect pollutants in the air outside the main body through the electric field.

[0007] 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.

[0008] The dust collecting component includes a dust collecting surface. After being powered on, ions are accumulated inside the dust collecting component. 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. The polarized pollutants 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. 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.

[0009] Among them, at least part of the dust collecting surface on the dust collecting component is an exposed surface exposed to the outside of the air purification device. The exposed dust collecting surface can form an electric field area on the outside of the air purification device, thereby directly collecting pollutants outside the air purification device through the electric field area.

[0010] It can be seen that the present application, by setting an exposed dust collecting surface and cooperating with the exposed dust collecting surface, enables the air purification device to directly collect pollutants in the outside air, eliminating the structure of introducing air into the air purification device in the related art, and abolishing the internal purification scheme. Compared with the internal purification scheme, without the restriction of the internal structure, the area of ​​the exposed dust collecting surface is easier to be enlarged, so as to improve the purification capacity and purification efficiency of the air purification device through a large area of ​​the dust collecting surface, and the front side of the exposed dust collecting surface is not easily blocked, which is conducive to expanding the coverage area of ​​the electric field area, so as to further improve the purification capacity and purification efficiency of the air purification device, thereby solving the technical problems of insufficient purification capacity and low purification efficiency in the related art. At the same time, the exposed dust collecting surface is less difficult to clean, and the user can directly wipe off the pollutants on the exposed dust collecting surface to avoid excessive pollutants adhering to the dust collecting surface, thereby solving the technical problems of high cleaning difficulty and poor user experience in the related art.

[0011] 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.

[0012] 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.

[0013] 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:

[0014] Visible particles: particles with a diameter of 10 microns or less, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0015] 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.

[0016] 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.

[0017] In addition, the control method of the air purification device in the above technical solution provided by the utility model may also have the following additional technical features:

[0018] In some technical solutions of the utility model, optionally, the main body includes: a discharge component, which is used to discharge toward the area where at least part of the exposed dust collecting surface is facing; wherein the dust collecting assembly 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.

[0019] In this technical solution, the air purification device also includes a discharge component, the discharge end of the discharge component faces the electric field area outside the air purification device, the discharge component can release ions to the electric field area, and the released ions can act on pollutants in the electric field area. Specifically, the air purification device also includes a power supply component, one of the positive and negative electrodes on the power supply component is connected to the dust collection component, and the other is connected to the discharge component, so that the polarity of the ions accumulated in the dust collection component and the ions released by the discharge component are opposite.

[0020] 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, making up for the shortcomings of electric field adsorption, and improving the purification capacity of the air purification equipment.

[0021] 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.

[0022] 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.

[0023] In some technical solutions of the present utility model, optionally, the discharge component includes a connecting end and an emitting end, the connecting end is connected to the bracket, and the emitting end is used for discharging.

[0024] 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 supplied, the discharge needle can release ions, and the ions can attach to pollutants in the electric field area.

[0025] Specifically, the discharge component includes a discharge needle or a discharge brush.

[0026] In some technical solutions of the utility model, 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.

[0027] 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 utility model, optionally, the air purification device also includes: a base, and the dust collecting component and the discharge component are arranged on the base.

[0028] In some technical solutions of the utility model, optionally, the main body also includes: a base, and the dust collecting component and the discharge component are arranged on the base; the dust collecting component is plate-shaped, and the dust collecting component is at least partially located outside the base.

[0029] 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.

[0030] 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.

[0031] On this basis, the dust collecting component is in the shape of a plate, and the plate-shaped dust collecting component is installed above the base. After the dust collecting component is assembled, at least part of the dust collecting surface on the dust collecting component is exposed to the outside of the base to form an electric field area above the base, thereby collecting pollutants in the air near the base through the electric field area.

[0032] Providing the dust collecting component in a plate shape is beneficial to increasing the total area of ​​the exposed dust collecting surface, thereby improving the purification capacity and purification efficiency of the air purification device by increasing the exposed area of ​​the dust collecting surface.

[0033] Specifically, the cross-sectional shapes of the plate-shaped dust collecting assembly include: rectangular, arc-shaped, and ring-shaped.

[0034] In some technical solutions of the present invention, optionally, the base includes a slot, and the dust collection component is partially inserted into the slot.

[0035] In this technical solution, a slot is provided on the base, the opening of the slot is opened at the top of the base, the shape of the slot is adapted to the outer contour of the dust collecting assembly, and the dust collecting assembly can be assembled by plugging the dust collecting assembly into the slot during use. It can be seen that the slot can play a positioning role for the dust collecting assembly to ensure that the dust collecting assembly can be fixed in a predetermined working position.

[0036] At the same time, the dust collection component can be disassembled and assembled through simple plugging and unplugging actions, which helps to reduce the difficulty of cleaning the dust collection component. The specific user can pull the dust collection component out of the slot and reinsert it into the slot after wiping is completed.

[0037] On this basis, after completing the plug-in installation of the dust collecting component, the dust collecting component is partially inserted into the slot and partially located outside the slot, so that the dust collecting surface on the dust collecting component is at least partially exposed to the outside of the slot, thereby ensuring the pollutant adsorption efficiency and adsorption capacity of the dust collecting component.

[0038] In some technical solutions of the present utility model, optionally, the dust collecting assembly is connected to the base, and the dust collecting assembly is entirely located outside the base.

[0039] In this technical solution, the dust collecting assembly is fixed above the base. After the dust collecting assembly is assembled, the dust collecting assembly as a whole is located on the outside of the base, so that the dust collecting surface on the dust collecting assembly is completely exposed on the outside of the base to avoid the base blocking the dust collecting surface, thereby improving the purification efficiency and purification capacity of the air purification equipment by increasing the exposed area of ​​the dust collecting surface.

[0040] Specifically, the dust collecting assembly can be fixedly connected to the outside of the base by means of connecting parts such as screws, and the dust collecting assembly can also be connected to the outside of the base by means of buckles.

[0041] In some technical solutions of the utility model, optionally, the main body also includes: a frame, and the dust collecting assembly is arranged in the frame; the frame includes a window, and the dust collecting surface is exposed through the window.

[0042] In this technical solution, the air purification device also includes a frame, which is connected to the base, has a receiving cavity formed inside the frame, and has a window connecting the receiving cavity and the space outside the frame. The dust collecting assembly is installed in the receiving cavity, and the frame can position, protect and support the dust collecting assembly to reduce the possibility of damage to the dust collecting assembly due to external impact.

[0043] On this basis, the dust collecting surface on the dust collecting component is exposed through the window. During operation, the dust collecting component forms an electric field area in front of the window. The pollutants in the electric field area move toward the dust collecting surface inside the window under the action of Coulomb force and are finally captured by the dust collecting surface. On the one hand, the window can reduce the probability of the dust collecting surface being scratched and collided. On the other hand, the window can gather the pollutants adsorbed on the dust collecting surface and block the airflow blowing toward the dust collecting surface to reduce the possibility of secondary pollution caused by pollutants on the dust collecting surface.

[0044] During the cleaning process, users can directly wipe the pollutants on the dust collecting surface on the inside of the window, and can also disassemble the frame and perform a deep cleaning on the dust collecting surface.

[0045] In some technical solutions of the utility model, 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.

[0046] 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.

[0047] In some technical solutions of the utility model, the air purification device may further include: a bracket, which is arranged on the base, and a discharge component is arranged on the bracket. The discharge component includes a discharge needle, and the number of the discharge needles is multiple; the multiple discharge needles are arranged side by side on the bracket.

[0048] In this technical solution, the air purification device further comprises a bracket, which is used to position and support the discharge component. The discharge component can release ions toward the discharge port it faces after being energized.

[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 schemes of the utility model, 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 is 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Specifically, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0057] 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.

DETAILED DESCRIPTION

[0071] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. 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.

[0072] 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.

[0073] Refer to the following Figures 1 to 9 An air purification device according to some embodiments of the present invention is described.

[0074] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the utility model provides an air purification device 100, and the air purification device 100 includes: a main body 1002; a dust collecting component 120, which is arranged on the main body 1002, and 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 at least partially exposed. At least part of the exposed dust collecting surface 122 is used to collect pollutants 200 in the air outside the main body 1002 through the electric field.

[0075] Figure 2 The arrow a in the middle shows the moving direction of the pollutant 200 in the air.

[0076] Figure 4 The arrow b in the middle shows the ions released by the discharge component 144 .

[0077] 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 .

[0078] The dust collecting component 120 includes a dust collecting surface 122. After being powered on, the dust collecting component 120 accumulates ions inside. Under the action of the accumulated ions, an electric field can be generated. The electric field forms an electric field area in front of the dust collecting surface 122. 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 the adsorption effect, the concentration of the pollutants 200 in the electric field area is reduced. 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.

[0079] Among them, at least part of the dust collecting surface 122 on the dust collecting component 120 is an exposed surface exposed to the outside of the air purification device 100. The exposed dust collecting surface 122 can form an electric field area on the outside of the air purification device 100, thereby directly collecting pollutants 200 outside the air purification device 100 through the electric field area.

[0080] It can be seen that the present application, by setting an exposed dust collecting surface 122 and cooperating with the exposed dust collecting surface 122, enables the air purification device 100 to directly collect pollutants 200 in the outside air, eliminating the structure of introducing air into the air purification device in the related art, and abolishing the internal purification scheme. Compared with the internal purification scheme, without the restriction of the internal structure, the area of ​​the exposed dust collecting surface 122 is easier to be enlarged, so as to improve the purification capacity and purification efficiency of the air purification device 100 through the large area of ​​the dust collecting surface 122, and the front side of the exposed dust collecting surface 122 is not easily blocked, which is conducive to expanding the coverage area of ​​the electric field area, so as to further improve the purification capacity and purification efficiency of the air purification device 100, thereby solving the technical problems of insufficient purification capacity and low purification efficiency existing in the related art. At the same time, the exposed dust collecting surface 122 is relatively easy to clean, and the user can directly wipe off the pollutants 200 on the exposed dust collecting surface 122 to avoid excessive adhesion of pollutants 200 on the dust collecting surface 122, thereby solving the technical problems of high cleaning difficulty and poor user experience in related technologies.

[0081] 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.

[0082] 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 saving space for arranging air ducts and fans, and providing convenient conditions for the miniaturization and lightweight design of the air purification equipment 100.

[0083] 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:

[0084] Visible particles: particles with a diameter of 10 microns or less, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0085] 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.

[0086] 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.

[0087] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of the utility model, optionally, the main body 1002 includes: a discharge component 144, which is used to discharge toward the area toward which at least part of the exposed dust collecting surface 122 is directed; wherein the dust collecting assembly 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.

[0088] In this embodiment, the air purification device 100 further includes a discharge component 144, the discharge end of the discharge component 144 is toward the electric field area outside the air purification device 100, and the discharge component 144 can release ions to the electric field area, and the released ions can act on the pollutants 200 in the electric field area. Specifically, the air purification device 100 also includes a power supply component, and one of the positive and negative electrodes on the power supply component is connected to the dust collection component 120, and the other is connected to the discharge component 144, so that the ions accumulated inside the dust collection component 120 and the ions released by the discharge component 144 have opposite polarities.

[0089] The ions released by the discharge component 144 will adhere to the pollutants 200 in the electric field area, so that the pollutants 200 have an 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, and accelerating the pollutants 200 to move toward the dust collecting surface 122, thereby improving the adsorption capacity of the dust collecting component 120, compensating for the deficiencies of electric field adsorption, and improving the purification capacity of the air purification device 100.

[0090] Specifically, 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.

[0091] Specifically, 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 110. 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.

[0092] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, optionally, the main body 1002 also includes: a base 110, a dust collecting assembly 120 and a discharge component 144 are arranged on the base 110; the dust collecting assembly 120 is plate-shaped, and the dust collecting assembly 120 is at least partially located on the outside of the base 110.

[0093] In this embodiment, the air purification device 100 also includes a base 110, on which the dust collecting assembly 120 and the discharge component 144 are installed. The base 110 is used to provide positioning and support for the dust collecting assembly 120 and the discharge component 144, and at the same time lock the relative position between the dust collecting assembly 120 and the discharge component 144.

[0094] 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.

[0095] On this basis, the dust collecting component 120 is in the shape of a plate, and the plate-shaped dust collecting component 120 is installed above the base 110. After the dust collecting component 120 is assembled, at least part of the dust collecting surface 122 on the dust collecting component 120 is exposed to the outside of the base 110 to form an electric field area above the base 110, thereby collecting pollutants 200 in the air near the base 110 through the electric field area.

[0096] Setting the dust collecting component 120 into a plate shape is beneficial to increasing the total area of ​​the exposed dust collecting surface 122 , thereby improving the purification capacity and purification efficiency of the air purification device 100 by increasing the exposed area of ​​the dust collecting surface 122 .

[0097] Specifically, the cross-sectional shapes of the plate-shaped dust collecting assembly 120 include: rectangular, arc-shaped, and ring-shaped.

[0098] like Figure 1 As shown, in some embodiments of the present invention, optionally, the base 110 includes a slot 1102 , and the dust collection assembly 120 is partially inserted into the slot 1102 .

[0099] In this embodiment, a slot 1102 is provided on the base 110, and the opening of the slot 1102 is opened at the top of the base 110. The shape of the slot 1102 is adapted to the outer contour of the dust collecting assembly 120. During use, the dust collecting assembly 120 is plugged into the slot 1102 to complete the assembly of the dust collecting assembly 120. It can be seen that the slot 1102 can play a positioning role for the dust collecting assembly 120 to ensure that the dust collecting assembly 120 can be fixed at a predetermined working position.

[0100] At the same time, the dust collecting component 120 can be disassembled and assembled by simple plugging and unplugging actions, which is helpful to reduce the difficulty of cleaning the dust collecting component 120. Specifically, the user can pull out the dust collecting component 120 from the slot 1102 and reinsert it into the slot 1102 after wiping is completed.

[0101] On this basis, after completing the plug-in installation of the dust collecting component 120, the dust collecting component 120 is partially inserted into the slot 1102 and partially located outside the slot 1102, so that the dust collecting surface 122 on the dust collecting component 120 is at least partially exposed to the outside of the slot 1102, thereby ensuring the adsorption efficiency and adsorption capacity of pollutants 200 of the dust collecting component 120.

[0102] like Figure 2 As shown, in some embodiments of the present invention, optionally, the dust collecting assembly 120 is connected to the base 110 , and the dust collecting assembly 120 is located as a whole outside the base 110 .

[0103] In this embodiment, the dust collecting component 120 is fixed above the base 110. After the dust collecting component 120 is assembled, the dust collecting component 120 is located as a whole on the outside of the base 110, so that the dust collecting surface 122 on the dust collecting component 120 is completely exposed to the outside of the base 110, so as to avoid the base 110 blocking the dust collecting surface 122, thereby improving the purification efficiency and purification capacity of the air purification device 100 by increasing the exposed area of ​​the dust collecting surface 122.

[0104] Specifically, the dust collecting assembly 120 can be fixedly connected to the outside of the base 110 by means of connecting parts such as screws, and the dust collecting assembly 120 can also be connected to the outside of the base 110 by means of buckles.

[0105] like Figure 3 As shown, in some embodiments of the present invention, optionally, the main body 1002 further includes: a frame 150, and the dust collecting assembly 120 is disposed in the frame 150; the frame 150 includes a window 1502, and the dust collecting surface 122 is exposed through the window 1502.

[0106] In this embodiment, the air purification device 100 further includes a frame 150, which is connected to the base 110, and a receiving cavity is formed inside the frame 150. The frame 150 is also provided with a window 1502 connecting the receiving cavity and the external space of the frame 150. The dust collecting assembly 120 is installed in the receiving cavity, and the frame 150 can position, protect and support the dust collecting assembly 120, so as to reduce the possibility of the dust collecting assembly 120 being damaged by external impact.

[0107] On this basis, the dust collecting surface 122 on the dust collecting component 120 is exposed through the window 1502. During operation, the dust collecting component 120 forms an electric field area on the front side of the window 1502. The pollutants 200 in the electric field area move toward the dust collecting surface 122 inside the window 1502 under the action of the Coulomb force, and are finally captured by the dust collecting surface 122. On the one hand, the window 1502 can reduce the probability of the dust collecting surface 122 being scratched and collided. On the other hand, the window 1502 can gather the pollutants 200 adsorbed on the dust collecting surface 122, and can also block the airflow blowing toward the dust collecting surface 122, so as to reduce the possibility of secondary pollution of the pollutants 200 on the dust collecting surface 122.

[0108] During the cleaning process, the user can directly wipe the pollutants 200 on the dust collecting surface 122 inside the window 1502, and can also disassemble the frame 150 to perform deep cleaning on the dust collecting surface 122.

[0109] like Figure 5 As shown, 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.

[0110] 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.

[0111] like Figure 3 As shown, in some embodiments of the present invention, optionally, the discharge component 144 includes a connecting end and an emitting end, the connecting end is connected to the bracket 142, and the emitting end is used for discharging.

[0112] In this embodiment, the discharge component 144 is a discharge needle, which includes a connection end and an emission end. The connection 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 connection end. After power is supplied, the discharge needle can release ions, and the ions can attach to the pollutants 200 in the electric field area.

[0113] Specifically, the discharge member 144 includes a discharge needle or a discharge brush.

[0114] like Figure 5 and Figure 6 As shown, in some embodiments of the utility model, 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 source, 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 source, and the second voltage regulator 180 is used to adjust the potential of the discharge component 144 to be lower than the ground potential.

[0115] In this embodiment, 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. In some embodiments of the present invention, optionally, the air purification device 100 further includes: a base 110 , and a dust collecting assembly 120 and a discharge component 144 are disposed on the base 110 .

[0116] like Figure 3 As shown, in some embodiments of the present invention, optionally, the air purification device 100 further includes: a bracket 142, which is arranged on the base 110, and a discharge component 144 is arranged on the bracket 142. The discharge component 144 includes a discharge needle, and the number of the discharge needles is multiple; the multiple discharge needles are arranged side by side on the bracket 142.

[0117] In this embodiment, the air purification device 100 further includes a bracket 142, which is used to position and support a discharge component 144. The discharge component 144 can release ions toward the discharge port it faces after being energized.

[0118] 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 component 120 on the pollutants 200.

[0119] like Figure 7 As shown, in some embodiments of the utility model, 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.

[0120] 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, the two middle guard plates 124 both face the conductive component 126 and do not form dust collecting surfaces 122, while 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] Specifically, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0126] 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 .

[0127] In this embodiment, the dust collecting surface 122 is a plane, or the dust collecting surface 122 is a smooth curved surface.

[0128] 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.

[0129] 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.

[0130] like Figure 8 As shown, the figure shows the electric field area generated by the dust collecting component 120 after being energized.

[0131] 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.

[0132] ρ1 is the concentration value of the pollutant 200 in the first sub-region, ρ2 is the concentration value of the pollutant 200 in the second sub-region, ρ3 is the concentration value of the pollutant 200 in the third sub-region, and ρ4 is the concentration value of the pollutant 200 in the fourth sub-region.

[0133] Among them, ρ1<ρ2<ρ3<ρ4.

[0134] Arrow d shows the moving direction of the pollutant 200, V1 is the moving speed of the pollutant 200 in the first sub-region, V2 is the moving speed of the pollutant 200 in the second sub-region, V3 is the moving speed of the pollutant 200 in the third sub-region, and V4 is the moving speed of the pollutant 200 in the fourth sub-region.

[0135] Among them, V1>V2>V3>V4, that is, the greater the concentration difference, the faster the movement speed.

[0136] like Fig. 9 As shown, the air purification device 100 provided in the present application includes a dust collecting component 120, an ion wind component and a discharge component 144. The dust collecting component 120 includes a guard plate 124 and a conductive component 126. The guard plate 124 is arranged on both sides of the conductive component 126. The conductive component 126 is made of a metallic conductive material or a non-metallic conductive material, and a large specific area can be used to store a large number of negative ions.

[0137] 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 126 can also be a combination or compound of metallic conductive materials and / or non-metallic conductive materials. Optionally, the conductive component 126 is a graphene aluminum wire layer.

[0138] The material of the protective plate 124 can be at least one of glass, plastic or rubber. The protective plate 124 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 generated, and air pollutants 200 such as PM2.5, dust, and volatile substances can move toward the protective plate 124 in the direction indicated by the arrow M, and then the air pollutants 200 can be adsorbed on the surface of the protective plate 124.

[0139] The ion wind component and / or the discharge component 144 can transport negative ions to the dust collecting component 120 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.

[0140] 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.

[0141] 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.

[0142] 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 overlapping positive and negative electron centers. Under normal circumstances, the positive and negative bound charges inside a dielectric that has not been acted upon by an electric field cancel each other out on average, and do not show electrical properties macroscopically. Under the action of an external electric field, the local movement of bound charges causes electrical properties to be displayed macroscopically, 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. The conductive component 126 generates an electric field, which generates polarized charges on substances (such as air pollutants 200, etc.) in its electric field, and then adsorbs these substances on the surface of the dust collecting component 120 based on the principle that charges of opposite signs attract.

[0143] Furthermore, the dust collecting component 120 is energized to generate an electric field, and 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 120. There will always be a low concentration area near the dust collecting component 120, allowing the particles to move over.

[0144] When the air pollutants 200 move to the electric field area of ​​the dust collecting component 120 , they will be polarized and thus adsorbed onto the dust collecting component 120 , and there will be an accelerated movement process when approaching the dust collecting component 120 .

[0145] The power supply component has a positive electrode and a negative electrode, one of the positive electrode and the negative electrode is connected to the dust collecting component 120, and the other is connected to the discharge component 144. The discharge component 144 releases electrons into the air, so that the air pollutants 200 are charged opposite to the dust collecting component 120, and are accelerated to be adsorbed to the dust collecting component 120. The purification efficiency is improved, and the discharge component 144 charges the air pollutants 200 and also has a sterilization effect.

[0146] 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 allow the airflow to flow through and sterilize the airflow.
