Description

Technical Field

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

[0002] At present, in the relevant technology, the air purification equipment is provided with an air inlet and an air outlet. The air outside the air purification equipment enters the air duct of the air purification equipment through the air inlet. The filter element or dust collecting net in the air duct removes the dust from the air before it flows out of the air purification equipment through the air outlet, thereby achieving air purification in the air purification equipment. The filter element and the dust collecting net are both consumables. The filter element and the dust collecting net need to be replaced regularly during the use of the air purifier, thereby making the use cost of the air purifier relatively high. The filter element and the dust collecting net also need to be used in conjunction with a fan, thereby allowing the air outside the air purification equipment to enter the air duct of the air purification equipment through the air inlet. However, the fan will generate noise during operation, thereby causing the air purification equipment to cause certain noise pollution to the indoor environment.

[0003] In the related art, the air purification equipment can also collect pollutants in the air through a dust collecting component. The dust collecting component is provided with a dust collecting surface. The pollutants in the air can be adsorbed on the dust collecting surface by the dust collecting component. However, the air pollutants in the areas on both sides of the dust collecting surface cannot face the dust collecting surface directly, which reduces the adsorption efficiency of the dust collecting component, and thereby reduces the purification effect of the air purification equipment on the air. Summary of the invention

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

[0005] To this end, a first aspect of the present invention provides an air purification device.

[0006] In view of this, the first aspect of the present invention provides an air purification device, including a main body, a dust collecting assembly and a functional device; the dust collecting assembly is installed on the main body, and the dust collecting assembly is provided with at least one dust collecting surface, and at least one dust collecting surface is distributed in a ring shape; the functional device is arranged at the upper or lower part of the dust collecting assembly; wherein, when the dust collecting assembly is energized, the dust collecting assembly can generate an electric field to collect air pollutants.

[0007] The air purification device provided by the present invention comprises a main body and a dust collecting assembly. The dust collecting assembly is installed on the main body, and the dust collecting assembly is then supported and fixed by the main body, thereby improving the stability of the dust collecting assembly during operation.

[0008] The dust collecting component is provided with at least one dust collecting surface. When the dust collecting component is powered on, it can generate an electric field, and the dust collecting surface can collect air pollutants, thereby purifying the air. Since the dust collecting component can collect air pollutants on the dust collecting surface through the electric field generated by itself when the dust collecting component is powered on, the air purification device no longer needs to use a fan to drive the air flow movement when collecting air pollutants, thereby avoiding the noise generated by the fan when working to pollute the indoor environment, thereby reducing the noise pollution of the air purification device. In addition, the dust collecting component can collect air pollutants on the dust collecting surface through the electric field generated by itself, and the dust collecting component can be cleaned by wiping the dust collecting surface, so that the dust collecting component does not need to be replaced regularly, thereby reducing the use cost of the air purification device.

[0009] The air purification device also includes functional devices, which are arranged on the upper or lower part of the dust collecting component, so that the structure of the functional device and the dust collecting component is more compact, reducing the volume of the air purification device, and further reducing the space occupied by the air purification device.

[0010] At least one dust collecting surface is distributed in an annular shape, so that the dust collecting area of ​​the dust collecting component can cover a more comprehensive area in the circumferential direction of the air purification device, thereby increasing the dust collecting area of ​​the dust collecting component and further increasing the dust collecting effect of the air purification device. In addition, at least one dust collecting surface is distributed in an annular shape, which can reduce the volume of the air purification device, thereby reducing the space occupied by the air purification device. At least one dust collecting surface is distributed in an annular shape, and when air pollutants move toward the annular dust collecting surface, the movement direction of the air pollutants is perpendicular to the tangent direction of the dust collecting surface, thereby allowing the air pollutants to move directly toward the annular dust collecting surface, thereby increasing the dust collecting surface's adsorption efficiency on the air pollutants, thereby improving the air purification effect of the air purification device on the air.

[0011] Furthermore, the dust collecting component may be a dust collecting component having a circular ring shape in cross section.

[0012] The first dust collecting plate and the second dust collecting plate may also be dust collecting plates with a semi-circular cross section. The first dust collecting plate and the second dust collecting plate are opposite to each other, and enclose a dust collecting assembly with a circular cross section, thereby facilitating the disassembly and assembly of the dust collecting assembly, making it more convenient for users to disassemble and clean the dust collecting assembly.

[0013] Furthermore, when the dust collecting component is powered on, it can generate an electric field, and the air pollutants around the dust collecting surface will be adsorbed on the dust collecting surface, thereby realizing the collection of air pollutants. After the air pollutants around the dust collecting surface are adsorbed by the dust collecting surface, the concentration of the air around the dust collecting surface decreases, and the air concentration at a location farther from the dust collecting surface will be higher than the air concentration around the dust collecting surface. At this time, the air in the area with higher air concentration will move to the area with lower air concentration, and the air at a location farther from the dust collecting surface will move to the surrounding of the dust collecting surface. The dust collecting surface continues to adsorb the surrounding air pollutants, thereby realizing the circulation and purification of the air in a certain area, further improving the air purification effect of the air purification equipment on the air.

[0014] Furthermore, air pollutants can be solid particle pollutants in the air, including dust, smoke, particulate matter, bacteria, viruses, etc. Their diameters vary and can generally be divided into the following categories according to their diameters:

[0015] Visible particulate matter (PM10): Particles with a diameter of less than or equal to 10 microns, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0016] Fine particulate matter (PM2.5): Particles with a diameter of less than or equal to 2.5 microns cannot be seen by the naked eye, but have a greater impact on human health, such as automobile exhaust and factory exhaust.

[0017] Ultrafine particles (less than 0.1 microns): particles with a diameter of less than or equal to 0.1 microns 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.

[0018] It should be noted that there are many types of particulate matter in the air, with different sizes, and the specific situation needs to be judged based on factors such as the pollution source and the environment.

And because the air can flow into or out of the receiving chamber from the first air flow port and the second air flow port, the flow of air will drive the air outside the air purification device to flow together, thereby driving the air flow around the air purification device, thereby improving the fluidity of the air around the air purification device, and increasing the area where the air purification device can collect air pollutants.

The ions can drive the air to move toward the ion receiving component, thereby driving the air, and thus enabling the ion wind component to generate airflow. The ion wind component drives the air flow, so that the component driving the air flow has lower noise, thereby reducing the noise pollution of the air purification equipment to the surrounding environment.

[0033] In some technical solutions of the present invention, optionally, the number of the ion wind components is two, and the two ion wind components are respectively located on both sides of the dust collecting component.

[0037] The discharge component is directed toward the ionization area formed after the dust collecting component is energized. The discharge component can discharge toward the ionization area formed after the dust collecting component is energized, so that the air pollutants in the ionization area formed after the dust collecting component is energized can be charged, thereby improving the dust collecting component's ability to adsorb air pollutants, accelerating the speed at which the dust collecting component adsorbs air pollutants, and improving the efficiency of the dust collecting component in adsorbing air pollutants.

DETAILED DESCRIPTION

[0124] 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.

[0125] 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.

[0126] Refer to the following Figures 1 to 26 Air purification devices according to some embodiments of the present invention are described.

[0127] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, an air purification device is provided, including a main body 100, a dust collecting assembly 200 and a functional device 600; the dust collecting assembly 200 is installed on the main body 100, and the dust collecting assembly 200 is provided with at least one dust collecting surface 210, and at least one dust collecting surface 210 is distributed in a ring shape; the functional device 600 is arranged at the upper part or the lower part of the dust collecting assembly 200; wherein, when the dust collecting assembly 200 is powered on, the dust collecting assembly 200 can generate an electric field to collect air pollutants.

[0128] In this embodiment, the air purification device includes a main body 100 and a dust collecting assembly 200. The dust collecting assembly 200 is installed on the main body 100, and the dust collecting assembly 200 is supported and fixed by the main body 100 to improve the stability of the dust collecting assembly 200 during operation.

[0129] The dust collecting assembly 200 is provided with at least one dust collecting surface 210. When the dust collecting assembly 200 is powered on, it can generate an electric field, and the dust collecting surface 210 can collect air pollutants, thereby purifying the air. Since the dust collecting assembly 200 is powered on, the dust collecting assembly 200 can collect air pollutants on the dust collecting surface 210 through the electric field generated by itself. When collecting air pollutants, the air purification device no longer needs to drive the air flow movement through a fan, thereby avoiding the noise generated when the fan is working to pollute the indoor environment, thereby reducing the noise pollution of the air purification device. In addition, the dust collecting assembly 200 can collect air pollutants on the dust collecting surface 210 through the electric field generated by itself, and the dust collecting assembly 200 can be cleaned by wiping the dust collecting surface 210, so that the dust collecting assembly 200 does not need to be replaced regularly, thereby reducing the use cost of the air purification device.

[0130] The air purification device also includes a functional device 600, which is arranged at the upper or lower part of the dust collecting component 200, so that the structure of the functional device 600 and the dust collecting component 200 is more compact, reducing the volume of the air purification device, and further reducing the space occupied by the air purification device.

[0131] At least one dust collecting surface 210 is distributed in an annular shape, so that the dust collecting area of ​​the dust collecting component 200 can cover a more comprehensive area in the circumferential direction of the air purification device, thereby increasing the dust collecting area of ​​the dust collecting component 200 and further increasing the dust collecting effect of the air purification device. In addition, at least one dust collecting surface 210 is distributed in an annular shape, which can reduce the volume of the air purification device, thereby reducing the space occupied by the air purification device. At least one dust collecting surface 210 is distributed in an annular shape, and when air pollutants move toward the annular dust collecting surface 210, the movement direction of the air pollutants is perpendicular to the tangent direction of the dust collecting surface 210, thereby allowing the air pollutants to move directly toward the annular dust collecting surface 210, thereby increasing the adsorption efficiency of the dust collecting surface 210 on the air pollutants, thereby increasing the air purification effect of the air purification device on the air.

[0132] Furthermore, the dust collecting component 200 may be a dust collecting component 200 having a circular ring shape in cross section.

[0133] The first dust collecting plate 220 and the second dust collecting plate 230 may also be dust collecting plates with a semi-circular cross section. The first dust collecting plate 220 and the second dust collecting plate 230 are opposite to each other, and enclose a dust collecting assembly 200 with a circular cross section, thereby facilitating the disassembly and assembly of the dust collecting assembly 200, making it more convenient for users to disassemble and clean the dust collecting assembly 200.

[0134] Furthermore, when the dust collecting component 200 is powered on, it can generate an electric field, and the air pollutants around the dust collecting surface 210 will be adsorbed on the dust collecting surface 210, thereby realizing the collection of air pollutants. After the air pollutants around the dust collecting surface 210 are adsorbed by the dust collecting surface 210, the concentration of the air around the dust collecting surface 210 decreases, and the air concentration at a position farther from the dust collecting surface 210 will be higher than the air concentration around the dust collecting surface 210. At this time, the air in the area with higher air concentration will move to the area with lower air concentration, thereby causing the air at a position farther from the dust collecting surface 210 to move to the surrounding of the dust collecting surface 210, and the dust collecting surface 210 continues to adsorb the surrounding air pollutants, thereby realizing the circulation purification of air in a certain area, and further improving the air purification effect of the air purification device on the air.

[0135] Furthermore, air pollutants can be solid particle pollutants in the air, including dust, smoke, particulate matter, bacteria, viruses, etc. Their diameters vary and can generally be divided into the following categories according to their diameters:

[0136] Visible particulate matter (PM10): Particles with a diameter of less than or equal to 10 microns, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0137] Fine particulate matter (PM2.5): Particles with a diameter of less than or equal to 2.5 microns cannot be seen by the naked eye, but have a greater impact on human health, such as automobile exhaust and factory exhaust.

[0138] Ultrafine particles (less than 0.1 microns): particles with a diameter of less than or equal to 0.1 microns 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.

[0139] It should be noted that there are many types of particulate matter in the air, with different sizes, and the specific situation needs to be judged based on factors such as the pollution source and the environment.

[0140] This embodiment provides an air purification device. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0141] like Figure 1 and Figure 2 As shown, the main body 100 also includes a base 110 and a first bracket 120 ; the first bracket 120 is connected to the dust collecting assembly 200 , and the functional device 600 is connected to the first bracket 120 .

[0142] In this embodiment, the main body 100 also includes a base 110 and a first bracket 120. The first bracket 120 is connected to the dust collecting assembly 200, and the functional device 600 is connected to the first bracket 120, so that the dust collecting assembly 200 supports the functional device 600 through the first bracket 120, thereby improving the stability of the functional device 600.

[0143] Furthermore, an upper cover plate 180 is disposed on the upper portion of the first bracket 120 , and the upper cover plate 180 can support components located on the upper portion of the first bracket 120 .

[0144] A lower cover plate 190 is disposed at the lower portion of the first bracket 120 , and the lower cover plate 190 can support components disposed at the lower portion of the first bracket 120 .

[0145] This embodiment provides an air purification device. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0146] like Figure 1 and Figure 2 As shown, the functional device 600 includes an ion wind component 400 , which is disposed on the first bracket 120 and located at the upper or lower part of the dust collecting component 200 .

[0147] In this embodiment, the air purification device further includes an ion wind component 400, which is disposed on the first bracket 120, and the ion wind component 400 is supported by the first bracket 120.

And by providing the ion wind component 400, the ion wind component 400 can drive the air flow around the air purification device, thereby improving the fluidity of the air around the air purification device, and increasing the area where the air purification device can collect air pollutants.

[0148] Furthermore, if Figure 3 As shown, the body 100 is provided with a housing chamber 130, a first air flow outlet 140 and a second air flow outlet 150, and the ion wind component 400 is arranged in the housing chamber 130. The ion wind component 400 can drive the gas flow in the housing chamber 130, so that the air in the housing chamber 130 can flow out from one of the first air flow outlet 140 and the second air flow outlet 150, and the air outside the air purification device can flow in from the other air flow outlet of the first air flow outlet 140 and the second air flow outlet 150, and the air passing through the ion wind component 400 can be sterilized in the ion wind component 400, thereby improving the purification effect of the air purification device. And because the air can flow into or out of the housing chamber 130 from the first air flow outlet 140 and the second air flow outlet 150, the flow of air will drive the air outside the air purification device to flow together, thereby driving the air flow around the air purification device, thereby improving the fluidity of the air around the air purification device, and increasing the area where the air purification device can collect air pollutants.

[0149] The first air flow opening 140 is located at the upper part or the lower part of the dust collecting assembly 200 , or the second air flow opening 150 is located at the upper part or the lower part of the dust collecting assembly 200 , thereby realizing air intake or air outlet of the accommodating chamber 130 .

[0150] A fan may also be disposed in the accommodating chamber 130 to increase the flow speed of the air in the accommodating chamber 130 .

[0151] This embodiment provides an air purification device. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0153] In this embodiment, a first mesh port 164 is provided on the first frame 160, and the ion wind component 400 is opposite to the first mesh port 164, so that the airflow outside the air purification device can enter the first frame 160 through the first mesh port 164, and the air inside the first frame 160 can also flow out of the first frame 160 through the first mesh port 164, thereby enabling the ion wind component 400 to drive the air movement around the air purification device.

[0156] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the ion wind assembly 400 includes a second frame 410, an ion emitting component 420 and an ion receiving component 430. The second frame 410 is provided with a second air duct 440. The ion emitting component 420 is arranged in the second air duct 440. The ion receiving component 430 is arranged in the second air duct 440. The ions emitted by the ion emitting component 420 can move toward the ion receiving component 430, and the ions can drive the air along the Figure 8 The direction indicated by the middle arrow C moves toward the ion receiving component 430 to drive the air, thereby enabling the ion wind component 400 to generate airflow. The ion wind component 400 drives the air flow, so that the component driving the air flow has lower noise, thereby reducing the noise pollution of the air purification device to the surrounding environment.

[0157] This embodiment provides an air purification device. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

And the dust collecting state of the first dust collecting plate 220 and / or the second dust collecting plate 230 is controlled by the control assembly 300, so that the first dust collecting plate 220 and the second dust collecting plate 230 can be opened or closed as needed, thereby making the working state of the first dust collecting plate 220 and the second dust collecting plate 230 more suitable for the surrounding environment of the air purification device, improving the working efficiency of the air purification device, and reducing the energy consumption of the air purification device.

[0179] When the air concentration around the first dust collecting plate 220 and the second dust collecting plate 230 is high, that is, when there are more air pollutants, the first dust collecting plate 220 and the second dust collecting plate 230 can be controlled to open at the same time, thereby accelerating the purification speed of the air purification equipment on the surrounding air.

[0180] When the air concentration around the first dust collecting plate 220 and the second dust collecting plate 230 is low, that is, when there are fewer air pollutants, one of the first dust collecting plate 220 and the second dust collecting plate 230 can be controlled to open, thereby reducing the energy consumption of the air purification equipment.

[0222] A dust collecting assembly 200 may also be provided on the top of the air purification device, and the dust collecting assembly 200 is arranged upward.

[0223] Specifically, Fig.17 As shown, the air purification device may include, from bottom to top, a base 110 , a discharge component 500 , an ion wind component 400 , a dust collecting component 200 , an ion wind component 400 , a discharge component 500 and a dust collecting component 200 .

[0224] like Fig.18 and Fig.19 As shown, the air purification device may include, from bottom to top, a base 110 , a dust collecting component 200 , an ion wind component 400 , a discharge component 500 and a dust collecting component 200 .

[0225] like Fig. 20 As shown, the air purification device may also be composed of a base 110, a discharge component 500, an ion wind component 400 and a dust collection component 200 from bottom to top.

[0226] The air purification device may also be composed of a base 110 , an ion wind component 400 , a dust collecting component 200 , an ion wind component 400 and a dust collecting component 200 from bottom to top.

[0227] The air purification device may also be composed of a base 110 , a discharge component 500 , a dust collection component 200 , an ion wind component 400 and a dust collection component 200 from bottom to top.

[0228] like Fig.21 As shown, the air purification device may also be composed of a base 110, a discharge assembly 500, an ion wind assembly 400 and a dust collection assembly 200 from bottom to top, and the dust collection assembly 200 is located at the top. Fig. 22 As shown, the dust collection assembly 200 may also be located on the side walls and the top.

[0229] The air purification device may also include, from bottom to top, a base 110 , a discharge component 500 , and an ion wind component 400 .

[0230] The air purification device may also be composed of a base 110 and a dust collecting assembly 200 from bottom to top. Fig.23 As shown, the dust collection assembly 200 can be arranged on the side wall; Fig.24 As shown, the dust collecting assembly 200 may also be arranged on the top; the dust collecting assembly 200 may also be arranged on the top and the side wall.

[0231] like Fig.25 As shown, the air purification device provided in the present application includes a dust collecting component 200, an ion wind component 400 and a discharge component 500. The dust collecting component 200 includes a guard plate 240 and a conductive component 250. The guard plate 240 is arranged on both sides of the conductive component 250. The conductive component 250 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.

[0232] Metallic conductive materials include copper, aluminum, silver, iron, tin, gold, nickel, lead, magnesium, zinc, molybdenum, yttrium, tungsten, and cobalt, and 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 250 is a graphene aluminum wire layer.

[0233] The material of the protective plate 240 can be at least one of glass, plastic or rubber.

[0234] The protective plate 240 can be used as an adsorption structure, utilizing 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 protective plate 240 in the direction indicated by the arrow M, and the air pollutants can be adsorbed on the surface of the protective plate 240.

[0235] The ion wind component 400 and / or the discharge component 500 can transport negative ions to the dust collecting component 200 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.

[0236] Furthermore, based on Coulomb's law, the calculation formula of Coulomb force F 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 , in N·m 2 / Library 2 (N·m 2 / C 2 ). Coulomb force is the interaction force between stationary charged bodies.

[0237] 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.

[0238] 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 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 250 generates an electric field, which generates polarized charges on substances (such as air pollutants, etc.) in its electric field, and then adsorbs these substances on the surface of the dust collecting component 200 based on the principle that charges of opposite signs attract.

[0239] Furthermore, the dust collecting component 200 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 200. There will always be a low concentration area near the dust collecting component 200, allowing the particles to move over.

[0240] When air pollutants move to the electric field area of ​​the dust collecting component 200, they will be polarized and thus adsorbed onto the dust collecting component 200, and there will be an accelerated movement process when approaching the dust collecting component 200.

[0241] The power module has a positive electrode and a negative electrode, one of which is connected to the dust collecting component 200, and the other is connected to the discharge component 500. The discharge component 500 releases electrons into the air, so that the air pollutants are charged with an opposite charge to the dust collecting component 200, and are accelerated to be adsorbed to the dust collecting component 200. The purification efficiency is improved, and at the same time, the discharge component 500 charges the air pollutants and has a sterilization effect.

[0242] The positive and negative poles of the power module are connected to the ion generating pole of the ion wind component 400, and the other poles are connected to the ion receiving pole of the ion wind component 400. An airflow channel must be provided, and the ion generating pole and the ion receiving pole are installed in the airflow channel to allow airflow to flow through and sterilize the airflow.

[0243] like Fig.26 As shown, the figure shows the electric field area generated by the dust collecting assembly 200 after being energized.

[0244] In the direction from far to near, the front side of the dust collecting surface is divided into a plurality of fan-shaped sub-areas.

[0245] 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.

[0246] Among them, ρ1<ρ2<ρ3<ρ4.

[0247] Arrow F 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.

[0248] Among them, V1>V2>V3>V4, that is, the greater the concentration difference, the faster the movement speed.

[0249] The air purification device provided in the present application can directly power on the dust collection component 200 and generate an electric field after the user turns on the device. The dust collection component 200 can also be powered on after the sensor of the air purification device detects that the air pollutants in the air have reached a certain concentration, so that the dust collection component 200 can start collecting dust as needed. The dust collection component 200 can also control the open area of ​​the dust collection component 200 or the number of open dust collection surfaces 210 according to the concentration of air pollutants in each area of ​​the air purification device.

[0250] After the dust collecting component 200 starts working, the discharge component 500 and the ion wind component 400 can be turned on as needed, thereby improving the dust collecting effect and sterilization effect of the air purification equipment.
