DETAILED DESCRIPTION

[0052] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0053] According to the embodiment of the present application, an air purification device is provided. Referring to FIGS. 1-3, the air purification device comprises a frame 3, one side of the frame 3 is provided with an air inlet, and the other side is provided with an air outlet; a micro-electrostatic module, the micro-electrostatic module comprises a filter element 1, the filter element 1 comprises a plurality of air passages 10 for air flow, the filter element 1 is located inside the frame 3 and is arranged close to the air outlet; a charging mechanism 5, the charging mechanism 5 is located on the side of the filter element 1 away from the air outlet, the charging mechanism 5 is fixed inside the frame 3, and the charging mechanism 5 comprises a plurality of electrode heads 54 distributed on the surface of the filter element 1, so that the discharge area of the charging mechanism 5 covers the entire filter element 1.

[0054] It should be noted that the micro-electrostatic module and the charging mechanism 5 are integrated into the same frame 3 to reduce the thickness of the air purification device, the ion concentration released per unit volume is larger, thereby saving the installation space of the air purification device, and the application range is wider, especially in the purification scene where the installation size is very limited in the width direction, the overall performance of the air purification device can be better played; in addition, the plurality of electrode heads 54 are distributed on the surface of the filter element 1, so that the discharge is more sufficient, there is no charging blind area, the charging uniformity of particulate matter is better, and the charging effect is better.

[0055] In the air purification device of the embodiment, the charging mechanism 5 further comprises: a first accommodating groove 51, the first accommodating groove 51 is inside the frame 3; an electrode body, the electrode body is arranged along the length direction of the first accommodating groove 51, the electrode head 54 penetrates the groove wall of the first accommodating groove 51 and is connected with the electrode body, the arrangement direction of the electrode head 54 and the plane in which the frame 3 is located form an angle of not more than 90 degrees, and the electrode head 54 is arranged at intervals along the electrode body.

[0056] It should be noted that, on the one hand, since the first accommodating groove 51 accommodating the electrode body 52 is arranged inside the frame 3, the arrangement direction of the electrode head 54 and the plane in which the frame 3 is located forms an angle of less than 90 degrees, and the electrode head 54 does not exceed the outer surface of the frame 3, thereby reducing the overall thickness of the charging mechanism 5, and further saving the installation space of the air purification device; on the other hand, the new charging and discharging form is adopted, the electrode heads 54 are uniformly arranged, the discharge is more sufficient, there is no charging blind area, the charging uniformity of particulate matter is better, and the charging effect is better.

[0057] Specifically, the electrode head 54 is a carbon fiber brush, or a bundle of metal wires, or a metal tip. The carbon fiber brush comprises a plurality of bundle-shaped carbon fiber wires, an insulating tube, and is electrically connected to the electrode body 52 through a conductive metal wire.

[0058] The first accommodating groove 51 is made of insulating material, and the electrode body 52 and the connecting head for connecting the electrode head 54 and the electrode body 52 are sealed in the first accommodating groove 51 by insulating sealant.

[0059] In the air purification device of the embodiment, the first accommodating groove 51 is provided with a plurality of first accommodating grooves 51 arranged at intervals, and the electrode bodies 52 in different first accommodating grooves 51 are sequentially connected in head-tail mode to form an S-shaped bend.

[0060] Specifically, the plurality of electrode bodies 52 in different first accommodating grooves 51 can be electrically connected by wires 53 or by other means.

[0061] In the air purification device of the embodiment, referring to FIG. 4, the outer side of the groove wall of the first accommodating groove 51 is fixedly provided with a second accommodating groove 55 for accommodating the electrode head 54, and the second accommodating groove 55 is provided in one-to-one correspondence with the electrode head 54. The second accommodating groove 55 is used to support the electrode head 54 to avoid offset caused by bumping.

[0062] In the charging device of the embodiment, the included angle formed by the arrangement direction of the electrode head 54 and the plane in which the frame body 3 is located is greater than or equal to 0 degrees and less than or equal to 60 degrees, so as to further reduce the thickness of the charging device. The two sides of the first accommodating groove 51 are connected with the electrode head 54, and the distance between two adjacent electrode heads 54 on the same side of the same first accommodating groove 51 is equal to the distance between two adjacent first accommodating grooves 51. When the electrode head 54 is made of hard material such as metal tip, the electrode head 54 does not exceed the outer surface of the frame body 3, so as to reduce the installation space occupied by the charging device. When the electrode head 54 is made of flexible material such as carbon fiber brush, the electrode head 54 can exceed the outer surface of the frame body 3. Preferably, the length of the electrode head 54 exceeding the outer surface of the frame body 3 is not more than 50% of the total length of the flexible material. By utilizing the flexibility of the flexible material, the charging device can smoothly pass through the limited installation position when installed in a limited space, and after installation, the flexible material can automatically recover to its original state due to its self-recoverability and the front end of the electrode head 54 is an open space not less than the thickness space of the frame body 3, so as to increase the included angle between the arrangement direction of the electrode head 54 and the plane in which the frame body 3 is located as much as possible, and the flexible material is less likely to cause injury to the workers. From the charging principle, the larger the included angle, the better the charging effect.

[0063] It is worth mentioning that when the arrangement direction of the electrode head 54 and the plane where the frame body 3 is located form an angle greater than 60 degrees, it can be used in a scene with a larger installation space. For example, when the arrangement direction of the electrode head 54 is perpendicular to the plane where the frame body 3 is located, and a flexible electrode head material such as a carbon fiber brush is used, the electrode head 54 can protrude a certain distance from the outer surface of the frame body 3. Preferably, the length of the electrode head 54 protruding from the outer surface of the frame body 3 is not more than 50% of the total length of the flexible material. By taking advantage of the flexibility of the carbon fiber brush, it can smoothly pass through the restricted installation site, and after installation, the flexible material can automatically recover to its original state due to the self-recoverability of the flexible material. Similarly, it can also improve the utilization of the installation space, meet the same ionization effect, and make the ionization device thinner and more widely applicable.

[0064] In the air purification device of the embodiment, referring to FIG. 5, the arrangement direction of the electrode head 4 and the plane where the frame body 3 is located form an angle of 0 degrees, that is, the arrangement direction of the electrode head 4 is parallel to the plane where the frame body 1 is located, which is more convenient for production and processing, and the charging effect meets the use of the charging device. The two sides of the first accommodating groove 51 are connected with the electrode head 54, and the distance between the two electrode heads 54 located on the same side of the same first accommodating groove 51 is equal to the distance between the two first accommodating grooves 51 adjacent to each other; the electrode heads 54 located on the two sides of the same first accommodating groove 51 are arranged side by side to form a plurality of electrode head pairs, and the electrode head pairs located in different first accommodating grooves 51 are arranged in a matrix. This is the first arrangement mode of the electrode head 54.

[0065] In the air purification device of the embodiment, referring to FIG. 6, the arrangement direction of the electrode head 4 and the plane where the frame body 3 is located form an angle of 0 degrees, the two sides of the first accommodating groove 51 are connected with the electrode head 54, and the distance between the two electrode heads 54 located on the same side of the same first accommodating groove 51 is equal to the distance between the two first accommodating grooves 51 adjacent to each other; the electrode heads 54 located on the two sides of the same first accommodating groove 51 are arranged side by side to form a plurality of electrode head pairs, and the electrode head pairs located in different first accommodating grooves 51 are arranged in a staggered manner. This is the second arrangement mode of the electrode head 54.

[0066] It should be noted that the electrode head pairs are arranged in a staggered manner, and the electrode heads 54 located on the opposite sides of the two first accommodating grooves 51 partially overlap in the discharge area, and can effectively ensure that the discharge area completely covers the entire frame body 3.

[0067] In the air purification device of the embodiment, referring to FIG. 7, the angle formed by the arrangement direction of the electrode head 4 and the plane where the frame body 3 is located is 0 degrees, both sides of the first accommodating groove 51 are connected with the electrode head 54, and the distance between two electrode heads 54 located on the same side of the same first accommodating groove 51 is equal to the distance between two adjacent first accommodating grooves 51; the electrode heads 54 located on both sides of the same first accommodating groove 51 are staggered, and the electrode heads 54 on several first accommodating grooves 51 are arranged in the same way. This is the arrangement mode 3 of the electrode head 54.

[0068] In order to verify the performance difference of the three arrangement modes of the electrode head 54, a comparison test was conducted in a standard laboratory. The same micro electrostatic module (the micro electrostatic module is formed by wrapping a conductive material with a dielectric material to form an electrode plate, and capturing charged particles in the air by using the strong electric field between the electrode plates) was used, and then three kinds of charging mechanisms 5 were matched to compare the PM2.5 purification efficiency of the carbon fiber brush electrode head 54 under the same working environment and the same wind speed. In order to reduce the test error, the PM2.5 purification efficiency was compared by taking the average of three groups of continuous test data.

[0069] Through the comparison of the test data, it can be seen that the three charging mechanisms 5 matched with the same micro electrostatic module all have high PM2.5 purification efficiency, which can indicate that the three charging mechanisms 5 with the electrode head 54 form have good charging effect, and the charging effect: arrangement mode 2> arrangement mode 3> arrangement mode 1.

[0070] Preferably, in order to fully utilize the discharge area of the electrode head 54, several first accommodating grooves 51 are arranged in parallel and at equal distances, and the distance between the first accommodating groove 51 located on the side and the frame body 3 is not greater than 1 / 2 of the distance between two adjacent first accommodating grooves 51.

[0073] Preferably, the reinforcing ribs are added between the adjacent first accommodating grooves 51 to increase the structural strength and stability through the reinforcing ribs between the first accommodating grooves 51 when the area of the charging mechanism 5 is large.

By arranging the boss 41, embedding the boss 41 in the fixing groove 2, and clamping the boss 41 and the fixing groove 2, the support force of the fixing component 4 on the filter element 1 is increased, the filter element 1 is stopped and fixed by the boss 41, the dust holding surface of the filter element 1 occupied by the frame 31 is reduced, and the thickness of the frame is reduced.

[0092] Optionally, the boss 41 is an L-shaped boss.

[0093] In the air purification device of the embodiment, referring to FIGS. 12-15, the fixing groove 2 includes a first connecting surface 211 and a second connecting surface 212 connected with each other.

[0094] Specifically, the fixing groove 2 is arranged on the side wall of the filter element 1 to increase the wrapping of the frame 3 and the fixing component 4 on the filter element 1 and improve the fixing strength of the filter element 1.

[0095] It can be understood that the fixing groove 2 can also be arranged on the end surface of the filter element 1 and spaced from the first accommodating groove 51 located on the end surface, and in this case, the dust holding surface of the filter element 1 can be maximized.

[0096] Specifically, the fixed groove 2 is in L-shaped structure, and is fixed by being clamped with the boss 41. The fixed groove 2 in L-shaped structure can reduce the opening area of the fixed groove 2, and increase the dust holding surface of the filter element 1. In addition, the boss 41 is matched with the fixed groove 2 in L-shaped structure, which reduces the possibility of deformation of the frame 31, and improves the structural strength of the frame 31.

[0097] In the air purifying device of the embodiment, the second connecting surface 212 is an arc surface.

[0098] It should be noted that by setting the second connecting surface 212 as an arc surface, after the frame 3 and the filter element 1 are assembled, there is a gap in the fixed groove 2 except for the boss 41. At this time, the insulating glue can be injected to increase the stability of the assembly, and at the same time, the sealing effect of the filter element 1 is increased to prevent the conductive material in the filter element 1 from leaking and discharging.

[0099] In the air purifying device of the embodiment, the fixed groove 2 includes a first connecting surface 211, and the first connecting surface 211 is an inclined surface.

[0100] Specifically, the fixed groove 2 is arranged on the side wall of the filter element 1. By using a single fixed groove 2, the cross-sectional area and capacity of the fixed groove 2 can be reduced, the amount of insulating glue used can be reduced, and at the same time, the size of the avoiding groove 104 is reduced, and the available area of the conductive material 103 is increased.

[0101] Preferably, the first connecting surface 211 is an arc surface. By setting the first connecting surface 211 as an arc surface, compared with the first connecting surface 211 in inclined surface structure, when the insulating glue is filled in the fixed groove 2, the adhesion of the insulating glue can be increased, and the assembly strength of the filter element 1 and the frame 3 is increased.

[0102] In the air purifying device of the embodiment, the filter element 1 includes oppositely arranged first and second dust collecting surfaces 11 and 13, and a plurality of air passages 10 for air flow are arranged between the first and second dust collecting surfaces 11 and 13; the first dust collecting surface 11 is arranged to protrude from the frame 31 along the extension direction of the air passage 10; and / or, the second dust collecting surface 13 is arranged to protrude from the frame 31 along the extension direction of the air passage 10.

[0103] It can be understood that by using the filter element 1 assembly structure in the present application, the thickness of the filter element 1 can be thickened or a frame with a smaller width specification can be used, and the assembly of the filter element 1 can be stably realized. Increasing the thickness of the filter element 1 can increase the length of the air passage, thereby increasing the dust collecting efficiency of the filter element 1.

[0104] In some embodiments, the structure design of thickening the filter element 1 on one side can be used to thicken the first or second dust collecting surface 11 or 13 on one side.

[0105] In some embodiments, the structure design of increasing the thickness of both sides of the filter core 1 can be adopted simultaneously, and the first dust collection surface 11 and the second dust collection surface 13 are both thickened.

[0106] In the air purification device of the embodiment, the fixing component 4 includes the insulating glue 42 filled between the frame 31 and the fixing groove 2. By filling the insulating glue 42 in the fixing groove 2, the frame 31 and the fixing groove 2 are stably connected, and meanwhile, the sealing effect is achieved, preventing the problem of discharge of the conductive material due to the too thin and too close edge of the conductive material 103 in the fixing groove 2, and improving the electrical safety.

[0107] In the ultra-thin micro electrostatic module of the embodiment, the filter core 1 includes a plurality of dust collection sheets 100 arranged in stacks and a plurality of separation pieces 101 arranged between the dust collection sheets 100, and the air passage 10 is formed between the dust collection sheet 100 and the separation piece 101. The conductive material 103 is wrapped in the dust collection sheet 100, and the conductive material 103 includes the avoiding groove 104 corresponding to the fixing groove 2. The conductive material 103 is electrically connected to the high-voltage power supply through the electrode body 52.

[0108] It should be noted that the electrode plate is formed by wrapping the conductive material 103 with the dielectric material, and the strong electric field formed in the electrode plate after electrification is used to capture the charged particulate matters in the air.

[0109] Specifically, the electrode body 52 is in contact with the conductive material 103 in the dust collection sheet 100 to achieve electrical connection.

[0110] Specifically, after the fixing groove 2 is formed on the filter core 1, in order to prevent the conductive material in the dust collection sheet from being too close to the fixing groove 2 and prevent the discharge problem of the conductive material and the external conductive body, the conductive material is adaptively shrunk, and the avoiding groove 104 is formed on the conductive material 103 to avoid the fixing groove 2. The shape of the avoiding groove 104 is adapted to the shape of the fixing groove 2, the distance between the edge of the conductive material 103 and the edge of the dust collection sheet meets the electrical safety distance, and the electrical safety is ensured. At the same time, in order to ensure the purification effect of the micro electrostatic module, the larger the area of the conductive material 103, the greater the purification effect and dust holding capacity of the micro electrostatic module. Therefore, the distance between the edge of the avoiding groove 104 and the edge of the dust collection sheet is greater than the distance between the conductive material 103 at the non-avoiding groove 104 and the edge of the dust collection sheet, which ensures the electrical safety and maximizes the purification effect and dust holding capacity.
