Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filter plate and purifier. Background Technology

[0002] In the field of air purification, gas filter panels are often used to purify air (such as filtering or purifying particulate matter and harmful organic substances such as formaldehyde, benzene, ammonia, sulfur dioxide, carbon monoxide and nitrogen oxides). In addition, gas filter panels can also have functions such as sterilization, deodorization and dust prevention.

[0003] In related technologies, gas filter plates typically employ a single-sided structure and are often configured as simple perforated plates, mesh plates, or grid plates (e.g., the wind deflector component shown in Chinese Patent Publication CN106123286B, "An Air Conditioner Wind Deflector Device"). Figure 1 As shown, the aforementioned windbreak assembly includes a windbreak panel and at least one set of air filter panels fixedly mounted on the windbreak panel (each air filter panel has at least one layer of filter mesh). However, the structure of the aforementioned air filter panels and the arrangement of the air ducts are relatively simple, resulting in limited air purification effects and making it difficult to meet users' high air filtration requirements. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide a filter plate that increases the contact area between the airflow and the filter plate, while also increasing the residence time of the airflow on the filter plate, thereby enhancing the filtration effect of the filter plate on the airflow.

[0005] Another objective of this invention is to provide a purifier that uses the aforementioned filter plate.

[0006] According to a first aspect of the present invention, a filter plate includes a body, wherein two surfaces in the thickness direction of the body are a first surface and a second surface, respectively; a plurality of first air ducts, each disposed on one side of the body in the thickness direction, the plurality of first air ducts being radially spaced apart along the body, each first air duct extending circumferentially along the body, and one end of each first air duct penetrating the first surface; and a plurality of second air ducts, each disposed on the other side of the body in the thickness direction, the plurality of second air ducts being circumferentially spaced apart along the body, each second air duct extending radially along the body, one end of each second air duct communicating with the other end of the first air duct, and the other end of the second air duct penetrating the second surface.

[0007] According to the filter plate of this utility model embodiment, a plurality of first air channels extending circumferentially along the body are provided on one side of the body in the thickness direction, and a second air channel extending radially along the body is provided on the other side of the body in the thickness direction.

[0009] According to some embodiments of the present invention, each second air duct sequentially includes a first air duct segment and a second air duct segment that are connected to each other along the direction away from the center of the main body. In this case, along the direction away from the center of the main body, the minimum distance between two adjacent first air duct segments first gradually increases and then gradually decreases; and along the direction away from the center of the main body, the minimum distance between two adjacent second air duct segments gradually increases.

[0010] According to some embodiments of the present invention, a vent is formed on the main body, one end of each second air duct in the length direction is connected to the vent, and the other end of each second air duct in the length direction is connected to the side wall of the main body.

[0011] According to some embodiments of the present invention, the vent includes a first segment and a second segment that are connected to each other, the diameter of the first segment is larger than the diameter of the second segment, and one end of each second air duct in the length direction is connected to the first segment.

[0014] According to some embodiments of the present invention, there are multiple second sub-ducts, which are spaced apart radially along the main body, and the length of the second sub-ducts gradually decreases along the direction away from the center of the main body.

[0026] The following is for reference. Figures 2-4 A filter plate 100 according to a first aspect embodiment of the present invention is described.

[0027] like Figures 2-4 As shown, the filter plate 100 according to a first aspect embodiment of the present invention includes a body 1, a plurality of first air ducts 2, and a plurality of second air ducts 3. In the description of the present invention, "a plurality of" means two or more.

[0028] Specifically, in the thickness direction of body 1 (e.g., Figure 2The two sides of the body 1 (in the vertical direction) are the first surface 11 and the second surface 12, respectively. Multiple first air ducts 2 are provided on one side of the body 1 in the thickness direction, spaced apart radially along the body 1. Each first air duct 2 extends circumferentially along the body 1, and one end of each first air duct 2 penetrates the first surface 11. On the other hand, multiple second air ducts 3 are provided on the other side of the body 1 in the thickness direction, spaced apart circumferentially along the body 1. Each second air duct 3 extends radially along the body 1, one end of each second air duct 3 connects to the other end of a first air duct 2, and the other end of each second air duct 3 penetrates the second surface 12.

[0029] For example, in Figure 2 and Figure 3 In the example, the first air duct 2 is provided on the first surface 11 of the body 1, and multiple first air ducts 2 are spaced apart along the direction from the center of the body 1 to the edge of the body 1, so as to increase the flow area of ​​airflow on the first surface 11 of the body 1. The second air duct 3 is provided on the second surface 12 of the body 1, and multiple second air ducts 3 are spaced apart along the circumference of the body 1, thereby increasing the flow area of ​​airflow on the second surface 12 of the body 1.

[0030] In other words, on the projection surface of the thickness direction of the body 1, the extension direction of the first air duct 2 intersects with the extension direction of the second air duct 3, so that the first air duct 2 is connected to multiple second air ducts 3. When the airflow flows from the first air duct 2 to the second air duct 3, the body 1 can block the airflow to a certain extent, increasing the residence time of the airflow on the filter plate 100, thereby enhancing the filtering effect of the filter plate 100 on the airflow.

[0031] The first air duct 2 penetrates the first surface 11, and the second air duct 3 penetrates the second surface 12. The end of the first air duct 2 away from the first surface 11 is connected to the end of the second air duct 3 away from the second surface 12, so that the airflow can enter the first air duct 2 from the first surface 11, then enter the second air duct 3, and finally flow out from the second surface 12.

[0032] According to the embodiment of the present invention, the filter plate 100 has a plurality of first air ducts 2 extending circumferentially along one side of the thickness direction of the body 1, and a second air duct 3 extending radially along the body 1 on the other side of the thickness direction of the body 1. This increases the contact area between the airflow and the filter plate 100, and at the same time, the first air ducts 2 and the second air ducts 3 intersect, increasing the residence time of the airflow on the filter plate 100, thereby enhancing the filtering effect of the filter plate 100 on the airflow.

[0033] According to some embodiments of this utility model, refer to Figure 2 and Figure 3Each second air duct 3 includes at least one curved air duct section. This reduces the resistance to airflow within the second air duct 3, improves the smoothness of airflow within the second air duct 3, and increases the length of the second air duct 3, thereby further increasing the residence time of the airflow on the filter plate 100 and further improving the filtration efficiency of the body 1.

[0034] Furthermore, along the direction away from the center of the main body 1, each second air duct 3 sequentially includes a first air duct segment 31 and a second air duct segment 32 that are interconnected. Specifically, along the direction away from the center of the main body 1, the minimum distance between two adjacent first air duct segments 31 first gradually increases and then gradually decreases. Similarly, along the direction away from the center of the main body 1, the minimum distance between two adjacent second air duct segments 32 gradually increases.

[0035] Reference Figure 3 One end of the first air duct section 31 is close to the center of the main body 1, and the other end of the first air duct section 31 extends away from the center of the main body 1. The other end of the first air duct section 31 is approximately located in the middle of the center of the main body 1 to its edge. One end of the second air duct section 32 is connected to the edge of the main body 1, and the other end of the second air duct section 32 extends toward the center of the main body 1 and is connected to the other end of the first air duct section 31. This increases the integrity of the second air duct 3, allowing the airflow to flow stably along the second air duct 3 and achieve airflow filtration.

[0036] The minimum distance between the ends of two adjacent first air duct segments 31 that are near the center of the main body 1 is relatively small, and the minimum distance between the ends of two adjacent first air duct segments 31 that are far from the center of the main body 1 is also relatively small. Approximately at the middle position of the first air duct segment 31, the minimum distance between two adjacent first air duct segments 31 is relatively large. As a result, the first air duct segment 31 extends away from the center of the main body 1 until it bends in the middle section, thus lengthening the first air duct segment 31 to increase the contact area between the airflow and the filter plate 100 and improve the filtration effect of the filter plate 100 on the airflow.

[0037] The minimum distance between the ends of two adjacent second air duct sections 32 that are near the edge of the main body 1 is the largest, and the minimum distance between the ends of two adjacent second air duct sections 32 that are far from the edge of the main body 1 is the smallest. This allows the airflow to flow along the second air duct section 32 toward the edge of the main body 1, while ensuring the structural strength of the main body 1. This reduces the risk of the main body 1 being prone to breakage due to the small distance between two adjacent second air duct sections 32 at the edge of the main body 1, thereby extending the service life of the filter plate 100.

[0038] According to some embodiments of this utility model, refer to Figure 2 and Figure 3The main body 1 has ventilation holes 13 formed thereon. One end of each second air duct 3 along its length is connected to the ventilation hole 13, and the other end of each second air duct 3 along its length is connected to the side wall of the main body 1. The ventilation hole 13 is formed at the center of the main body 1, allowing airflow to flow along it. This increases the airflow rate on the filter plate 100, thereby preventing excessive airflow pressure from damaging the filter plate 100 during filtration, thus extending the service life of the filter plate 100 and enhancing its market competitiveness. The two ends of the second air duct 3 are connected to the ventilation hole 13 and the side wall of the main body 1, respectively. Airflow can flow from the ventilation hole 13 to the second air duct 3, and then flow along the second air duct 3 out from the edge of the main body 1. This improves the airflow flow on the second surface 12, further enhancing the filtration effect of the filter plate 100.

[0039] Furthermore, the vent 13 includes a first vent segment 131 and a second vent segment 132 that are interconnected. The diameter of the first vent segment 131 is larger than the diameter of the second vent segment 132. One end of each second air duct 3 in its length direction is connected to the first vent segment 131. Along the thickness direction of the body 1, the first vent segment 131 and the second vent segment 132 are connected. Airflow enters the first vent segment 131 from the first surface 11, flows through the first vent segment 131 to the second vent segment 132, and then flows out from the second surface 12. Because the diameter of the first vent segment 131 is larger than the diameter of the second vent segment 132, the flow velocity of the airflow decreases after flowing from the second vent segment 132 to the first vent segment 131. Since one end of the second air duct 3 in its length direction is connected to the first vent segment 131, the airflow can slowly flow to the second air duct 3, further increasing the residence time of the airflow on the body 1.

[0040] According to some embodiments of the present invention, each first air duct 2 is a circular annular air duct, and multiple first air ducts 2 are coaxially arranged on the body 1, thereby increasing the contact area between the airflow and the filter plate 100.

[0041] Furthermore, the plurality of first air ducts 2 include a plurality of first sub-air ducts 21 and at least one second sub-air duct 22, the second sub-air duct 22 being located outside the plurality of first sub-air ducts 21. For example, in Figure 2 In the example, eighteen circular first sub-air ducts 21 are coaxially arranged. Along the direction from the center of the body 1 to the edge of the body 1, the inner diameter of the first sub-air duct 21 that is farther from the center of the body 1 is larger than the outer diameter of the other first sub-air duct 21.

[0042] The main body 1 is roughly rectangular in shape, with second sub-air ducts 22 formed at its four corners. This increases the regularity of the first surface 11 of the main body 1, enriches the selectable paths for airflow on the first surface 11, and thus improves the filtration effect of the filter plate 100. The second sub-air ducts 22 are connected to the side walls of the main body 1, allowing airflow to exit from the ends of the second sub-air ducts 22 connected to the side walls of the main body 1. This prevents excessive airflow pressure during filtration from damaging the main body 1, thereby extending the service life of the filter plate 100 and enhancing its market competitiveness.

[0043] Furthermore, there are multiple second sub-air ducts 22, which are spaced apart radially along the main body 1. (Refer to...) Figure 2 Nine second sub-air ducts 22 are formed on the first surface 11 of the main body 1. The nine second sub-air ducts 22 are spaced apart along the direction from the center of the main body 1 to the edge of the main body 1, thereby increasing the area of ​​the air ducts on the first surface 11 of the main body 1 and further enriching the selectable paths of airflow on the first surface 11 of the main body 1.

[0044] Along the direction away from the center of the main body 1, the length of the second sub-air duct 22 gradually decreases, so that the second sub-air duct 22 is suitable for being formed at the corner of the roughly rectangular main body 1, so as to improve the regularity of the arrangement of air ducts on the first surface 11 of the main body 1.

[0045] According to some embodiments of this utility model, the body 1 is a foamed plastic part. Foamed plastic parts have advantages such as low thermal conductivity, good mechanical properties, good sound insulation, and high bending tensile strength. Using a foamed plastic part as the body 1 helps reduce the cost of the body 1, facilitates cleaning of the body 1, and promotes the reuse of the filter plate 100, thereby extending the service life of the filter plate 100.

[0046] Optionally, specific chemical components can be added during the manufacturing of the foamed plastic parts to achieve filtration of different gases. Specifically, a foamed plastic part is used as the body 1, forming multiple micropores on the filter plate 100. Therefore, by adding a formula, the function of filtering and eliminating various harmful substances in the airflow passing through the filter plate 100 can be achieved. Different formulas can be used in the production of the filter plate 100 for different harmful substances. Simultaneously, the micropores on the filter plate 100 have a diversion effect, effectively slowing down the rate of airflow exiting the filter plate 100 and increasing the residence time of the airflow on the filter plate 100, thereby further improving the filtration effect of the filter plate 100.

[0047] Furthermore, since the first air duct 2 and the second air duct 3 in the filter plate 100 are connected, the first hole segment 131 and the second hole segment 132 are connected, and the second sub-air duct 22 of the first air duct 2 is connected to the side wall of the body 1, and the end of each second air duct 3 away from the center of the body 1 is connected to the side wall of the body 1, it is convenient to clean the filter plate 100. That is, the cleaning liquid can flow in the first hole segment 131 and the second hole segment 132 of the first air duct 2 and the second air duct 3 to quickly complete the cleaning. Then the cleaning liquid can flow out in any direction along the first surface 11, the second surface 12 and the side wall of the body 1, thereby improving the reusability of the filter plate 100, thereby improving the environmental friendliness of the filter plate 100 and extending the service life of the filter plate 100.

[0048] In practical use, airflow can be introduced into the filter plate 100 by mechanical pressurization to increase the airflow rate on the filter plate 100, reduce the resistance encountered by the airflow when passing through the filter plate 100, and improve the filtration effect of the filter plate 100 on the airflow.

[0049] Optionally, the cross-sectional shape of the filter plate 100 can be any of a square, rectangle, or sector. However, it is not limited to these. That is, the shape of the filter plate 100 can be adapted to actual application requirements.

[0050] Optionally, a buffer element is provided on the outer peripheral surface of the filter plate 100. The buffer element can be a sponge, a sealing ring, or a foam, but is not limited to these. The buffer element protects the filter plate 100 to avoid damage to the filter plate 100 during actual use.

[0052] According to the embodiments of the present invention, the purifier, by employing the above-mentioned filter plate 100, is conducive to increasing the filtration and purification effect of airflow, while improving the environmental performance of the purifier and extending its service life.
