Description
Technical Field
[0001] The utility model relates to the technical field of air purification, and particularly relates to an air purification device based on electric field adsorption. Background Art
[0002] With the acceleration of the industrialization process and the improvement of the urbanization level, the problem of air pollution is becoming increasingly serious. The main sources of fine particulate matter in the air mainly include fine particulate matter such as PM2.5 and PM10, as well as suspended microorganisms such as fungi, molds and their spore propagules. These pollutants directly threaten human health, especially the health of the respiratory system, and may lead to the occurrence and aggravation of respiratory diseases, infectious diseases and allergic diseases.
[0003] In the face of the problem of indoor air pollution, people's requirements for indoor air quality are getting higher and higher, which has promoted the continuous development of air purification technology. At present, the air purifiers commonly available on the market mainly adopt high-efficiency filter screens and activated carbon adsorption technology to treat particulate matter and organic matter in the air. These devices can remove pollutants in the air to a certain extent, but there are some disadvantages that cannot be ignored. First of all, the filter screen needs to be replaced regularly, which not only brings inconvenience to the user in operation, but also increases the later maintenance cost. If the filter screen cannot be replaced in time, the filter screen full of pollutants will instead become a new source of pollution, resulting in secondary pollution. Secondly, although some air purifiers adopt electrostatic dust collection technology, due to problems such as uneven electric field distribution and low filtration efficiency, the air treatment effect of these devices is not ideal.
[0004] Therefore, although the existing air purification technologies have alleviated the problem of indoor air pollution to a certain extent, there are still many deficiencies. They either have high maintenance costs and inconvenient operation, or have poor purification effects, and it is difficult to meet the high requirements of modern society for indoor air quality.
[0005] In view of the deficiencies of the existing technology, there is an urgent need to provide an air purification device based on electric field adsorption, optimize the electric field design, improve the air filtration efficiency of the electric field, achieve efficient removal of pollutants in the air, and ensure people's health and quality of life. Summary of the Utility Model
[0006] The utility model provides an air purification device based on electric field adsorption, which can improve the air filtration efficiency and achieve efficient removal of pollutants in the air.
[0007] In order to achieve the above object, the present application provides the following technical solutions:
[0008] An air purification device based on electric field adsorption, comprising a housing. The two opposite walls of the housing are open and communicate with each other. A plurality of grooves are arranged in an array along the opening direction on the inner side wall of the housing. An electrode plate is arranged in the housing, and the plane of the electrode plate is perpendicular to the opening direction of the housing. The electrode plate includes a frame body and a mesh discharge electrode plate. The frame body is detachably connected to the housing, and the mesh discharge electrode plate is fixedly connected to the frame body. Discharge needles are inserted at the intersections of the grids in the mesh discharge electrode plate, and the discharge needles are distributed along the opening direction. Mesh isolation covers parallel to the electrode plate are symmetrically arranged on both sides of the electrode plate, and the axial extension directions of the respective discharge needles pass through the inner regions of the corresponding grids on the mesh isolation covers respectively.
[0009] The principle and advantages of the present utility model are as follows: In this solution, by arranging discharge needles at the intersections of the grids on the mesh discharge electrode plate in the housing, an efficient and uniform electric field distribution is formed, ensuring the uniformity of the electric field action area in space, so that the air flowing through the housing can all be subjected to an effective electric field action, and the pollutants therein are widely and uniformly activated into a plasma state and decomposed. Compared with the traditional partial discharge or uneven electric field design, it can process the pollutants in the air more comprehensively, improve the removal efficiency of pollutants such as dust and bacteria in the air, and thus enhance the overall performance of the air purification device.
[0010] Secondly, the detachable design of the electrode plate greatly facilitates the disassembly, replacement and maintenance of the electrode plate. In the actual use process, since the electrode plate may face problems such as aging or damage, the detachable design makes the replacement process simple and fast, greatly reducing the maintenance cost and ensuring the long-term stable operation of the equipment.
[0011] In addition, the grooves arranged in an array along the opening direction on the inner side wall of the housing effectively prevent the occurrence of electric leakage by increasing the length of the current propagation path, improving the safety of the device. At the same time, by setting the mesh isolation cover to limit the electrode plate inside the housing, the use safety of the air purification device is significantly improved. The mesh isolation cover can not only prevent direct contact with the charged electrode plate, reducing the safety risk, but also its design takes into account the need for air circulation, so it will not have an adverse impact on the air purification effect.
[0012] Finally, the axial extension directions of the respective discharge needles pass through the inner regions of the corresponding grids on the mesh isolation cover respectively, avoiding direct coincidence with the grid bodies in the mesh isolation cover. This detailed design further prevents the leakage of current and enhances the safety performance of the overall device.
[0013] Furthermore, the axial extension directions of the respective discharge needles pass through the centers of the corresponding grids on the mesh isolation cover.
[0014] Beneficial effects: The axial extension direction of the discharge needle passes through the center of the corresponding grid on the mesh isolation cover, which can further increase the offset of the discharge path from the position where the grid body is located, thereby further preventing current leakage.
[0015] Furthermore, a conductive layer is plated on the surface of the mesh discharge electrode plate.
[0016] Beneficial effects: By plating a conductive layer on the surface of the mesh discharge electrode plate, effective conduction and electrification of each discharge needle are achieved. In addition, the setting of the conductive layer is beneficial to simplifying the internal structure design of the air purifier. Since the conductive layer is directly plated on the surface of the mesh discharge electrode plate, the use of additional conductive lines or components is reduced, making the internal structure more compact and also facilitating later disassembly, replacement, and maintenance work.
[0017] Furthermore, through holes are provided on the mesh discharge electrode plate.
[0018] Furthermore, through holes are provided on the housing.
[0019] Beneficial effects: Facilitate the setting of conductive lines.
[0020] Furthermore, the housing is an insulating housing.
[0021] Beneficial effects: The setting of the insulating housing, through its excellent insulation performance, effectively isolates the internal charged components from direct contact with the outside world, greatly reducing the risk of electric leakage. This not only protects the personal safety of users but also avoids performance degradation or damage of the equipment caused by electric leakage. The insulating housing is usually made of high-performance insulating materials such as plastics, rubbers, or specific composite materials, which can withstand a certain voltage without conducting electricity. Such a physical barrier provides a closed and safe working environment for the internal circuit and discharge components. Even under extreme conditions, such as high humidity or accidental contact of the equipment with a conductive object, the insulating housing can maintain its insulation performance and prevent current from leaking.
[0022] Furthermore, the grids in the mesh discharge electrode plate and the mesh isolation cover are all square grids. Description of the Drawings

[0031] Embodiment 1:
[0032] Embodiment 1 is basically as shown in the attached Figure 1 figure:
[0033] An air purification device based on electric field adsorption includes a housing 1. The housing 1 is an insulating housing 1, which effectively cuts off the direct connection between the internal charged components and the outside world, reducing the risk of electric leakage. In this embodiment, a plastic housing 1 is specifically used. As Figure 6 shown, the two opposite walls of the housing 1 are open and communicate with each other. As Figure 1 , Figure 5 shown, a plurality of grooves 2 are arranged in an array along the opening direction on the inner side wall of the housing 1, forming an inner side wall structure with a plurality of grooves 2 and protrusions arranged at intervals, so as to increase the current propagation path length of the internal charged components and further prevent the occurrence of electric leakage.
[0034] As Figure 1 shown, an electrode plate is provided inside the housing 1, and the plane of the electrode plate is perpendicular to the opening direction of the housing 1. As Figure 2 , Figure 3As shown, the electrode plate includes a frame body 3 and a mesh discharge electrode plate 4. The frame body 3 is detachably connected to the housing 1, and the mesh discharge electrode plate 4 is fixedly connected to the frame body 3, thus realizing the detachable connection between the electrode plate and the housing 1. During actual use, since the electrode plate may face problems such as aging or damage, the detachable design makes the replacement process simple and fast, greatly reducing the maintenance cost and ensuring the long-term stable operation of the device. In this embodiment, a clamping groove is provided on the inner side wall of the housing 1, and a protrusion corresponding to the clamping groove is provided on the outer side wall of the frame body 3. The frame body 3 is an insulating plastic frame body 3; the inner side wall of the frame body 3 and the outer side wall of the mesh discharge electrode plate 4 are fixedly connected by an adhesive bonding method. A conductive layer is plated on the surface of the mesh discharge electrode plate 4 for conducting electricity. In this embodiment, tin is plated on the surface of the mesh discharge electrode plate 4.
[0035] As Figure 2 shown, discharge needles 5 are inserted through the intersections of each grid in the mesh discharge electrode plate 4. The discharge needles 5 are distributed along the opening direction, and the distances between adjacent discharge needles 5 in the left-right and up-down directions are equal, which is beneficial to forming a uniform electric field. Mesh isolation covers 6 parallel to the electrode plate are symmetrically arranged on both sides of the electrode plate. In this embodiment, the electrode plate is arranged in the middle of the housing 1, and the mesh isolation covers 6 are respectively arranged at the two opening positions of the housing 1.
[0036] The axial extension directions of each discharge needle 5 respectively pass through the corresponding grids on the mesh isolation cover 6, that is, the axial extension directions of the discharge needles 5 pass through the internal areas of the corresponding grids; as Figure 4 shown, in this embodiment, the axial extension directions of each discharge needle 5 respectively pass through the centers of the corresponding grids on the mesh isolation cover 6, and the grids in both the mesh discharge electrode plate 4 and the mesh isolation cover 6 are square grids.
[0037] A plate through-hole 7 is provided on the mesh discharge electrode plate 4, and a housing through-hole 8 is provided on the housing 1. During actual application, one end of the conductive circuit is connected to a power supply, and the other end sequentially passes through the housing through-hole 8 and the plate through-hole 7 and is electrically connected to the conductive layer on the mesh discharge electrode plate 4 to realize the conduction of the discharge needles 5. After the discharge needles 5 are conductive, a highly efficient and uniform electric field distribution is formed. Air flows into the air purification device from one end of the opening of the housing 1. When passing through the electric field area in the housing 1, pollutants in the air are widely and uniformly activated into a plasma state and decomposed, thereby realizing the efficient removal of pollutants in the air.
