Description

Technical Field

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

[0002] Air filters, such as fresh air systems, air conditioners, and air purifiers, often require the installation of pleated filters in the air duct. The filter paper of pleated filters has a pleated shape, which can effectively increase the filtration area in a limited space, accommodate more impurities, and achieve higher filtration accuracy and efficiency.

[0003] Pleated filters are typically connected directly to a filter holder, which is then installed into the duct. However, this connection method is quite complex. Others manufacture filter devices with rectangular supports, which are then inserted directly into the duct. However, these products are bulky and difficult to transport. Furthermore, the integrated rectangular support cannot be reused, resulting in a waste of materials and resources, and does not meet the requirements of energy conservation and environmental protection.

[0004] Therefore, this utility model provides a filtration device that can effectively solve the above problems. It has a simple structure, is easy to assemble, and the side support can be reused, making it energy-saving and environmentally friendly. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a filtration device with a simple structure, convenient assembly, and reusable side support components, which is energy-saving and environmentally friendly.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A filtration device, comprising:

[0008] A pleated filter medium having two non-corrugated edges facing each other vertically and two corrugated edges facing each other horizontally, wherein the two non-corrugated edges can move closer to each other or further away to reduce or increase the volume of the pleated filter medium.

[0009] Two connectors are arranged opposite each other, and the connectors have snap-fit ​​holes on their left and right sides. The two connectors are respectively connected to the two non-corrugated edges of the pleated filter medium.

[0010] Two support members are arranged opposite each other on the left and right sides. Each support member has a connecting part at both the top and bottom. The connecting part extends in the direction of the connecting member. The connecting part has a locking block, which engages with the locking hole.

[0011] As an improvement of this utility model, the connecting part includes an outer clamping plate and an inner clamping plate, and a clamping groove is formed between the outer clamping plate and the inner clamping plate, and the end of the connecting member is inserted into the clamping groove.

[0012] As an improvement of this utility model, the card block is disposed in the middle of the inner clamping plate and protrudes from the surface of the inner clamping plate opposite to the pleated filter medium. The inner clamping plate is provided with deformation grooves on the left and right sides of the card block.

[0013] As an improvement of this utility model, the upper surface of the inner clamping plate is provided with a plurality of supporting ribs, and the supporting ribs are spaced apart. When the end of the connector is inserted into the clamping groove, the upper surface of the supporting ribs abuts against the surface of the connector near the pleated filter medium.

[0014] As an improvement of this utility model, the end of the card block is provided with a first guide surface. When the end of the connector is inserted along the clamping groove, the first guide surface abuts against the surface of the connector near the pleated filter medium, so as to allow the card block to slide and engage in the engaging hole.

[0015] As an improvement of this utility model, the end of the support rib is provided with a second guide surface. When the end of the connector is inserted along the clamping groove, the second guide surface abuts against the surface of the connector near the pleated filter medium, so as to allow the connector to be smoothly inserted into the clamping groove.

[0016] As an improvement of this utility model, the outer clamping plate is provided with a pressing notch in the middle. The pressing notch is arranged opposite to the card block. When the end of the connector is inserted into the clamping groove and the card block is engaged with the carding hole, the pressing notch allows the user's finger to pass through to drive the card block to disengage from the carding hole.

[0017] As an improvement of this utility model, the inner surface of the outer clamping plate is provided with a sliding groove, the outer surface of the connector is provided with a sliding rail, and the sliding rail is inserted into the sliding rail.

[0018] As an improvement of this utility model, both of the two connecting members are provided with a first edge protection plate on their front and rear sides. The first edge protection plate extends from the front and rear edges of the connecting member in a direction away from the outer surface of the connecting member. The first edge protection plate covers at least part of the pleated filter medium.

[0019] As an improvement of this utility model, a second edge protection plate is provided on both the front and rear sides of the two support members. The second edge protection plate extends from the front and rear edges of the support members in a direction away from the outer surface of the support members. The second edge protection plate covers at least part of the pleated filter medium. An insertion groove is formed between the inner clamping plate and the second edge protection plate. The first edge protection plate is inserted into the insertion groove.

[0020] The beneficial effects of this utility model are as follows: With the above-described structure, during use, the locking block is engaged in the locking hole, so that the two support members are connected to both sides of the two connectors to form a rectangular frame. The two connectors are respectively connected to the upper and lower ends of the pleated filter medium to provide support for the pleated filter medium, facilitating the user's transportation, storage, and installation of the product. Furthermore, when the support member is connected to the connector, the support member abuts against the corrugated edge, forming a seal between the frame and the pleated filter medium. Moreover, when the pleated filter medium is damaged, it can be easily replaced, and the support member can be reused, saving energy, protecting the environment, and reducing costs.

[0037] Reference Figures 1 to 8 A filtration device, comprising:

[0038] The pleated filter medium 100 has two non-corrugated edges 101 that are opposite each other vertically and two corrugated edges 102 that are opposite each other horizontally. The two non-corrugated edges 101 can move closer to each other or further away to reduce or increase the volume of the pleated filter medium 100.

[0039] Two connectors 200 are arranged opposite each other, and the connectors 200 are provided with snap-fit ​​holes 201 on the left and right sides. The two connectors 200 are respectively connected to the two non-corrugated edges 101 of the pleated filter medium 100.

[0040] Two support members 300 are arranged opposite each other on the left and right. Each support member 300 has a connecting part 310 at both the upper and lower ends. The connecting part 310 extends toward the direction of the connecting member 200. The connecting part 310 has a locking block 311, which is engaged with the locking hole 201.

[0041] With the above-described structure, during transportation, the two non-corrugated edges 101 are brought closer together, compressing the volume of the pleated filter medium 100. This results in a smaller product size, facilitating storage and transportation, reducing transportation costs, and saving storage space. In use, the locking block 311 is engaged in the locking hole 201, connecting the two support members 300 to both sides of the two connectors 200, forming a rectangular frame. The two connectors 200 are respectively connected to the upper and lower ends of the pleated filter medium 100, providing support for the pleated filter medium 100 and allowing the two non-corrugated edges to move closer together. The fixed spacing between the corrugated edges 101 ensures that the product can completely fill the air duct when inserted into it. The airflow within the duct can only pass through the corrugated filter medium 100, guaranteeing the filtration effect and facilitating product installation for users. Furthermore, when the support 300 is connected to the connector 200, the support 300 abuts against the corrugated edge 102, forming a seal between the frame and the corrugated filter medium 100. Moreover, when the corrugated filter medium 100 is damaged, it can be easily replaced, and the support 300 can be reused, saving energy, protecting the environment, and reducing costs.

[0042] In this embodiment, the connecting part 310 includes an outer clamping plate 320 and an inner clamping plate 330, with a clamping groove 301 formed between the outer clamping plate 320 and the inner clamping plate 330. The end of the connector 200 is inserted into the clamping groove 301. With this structure, during use, the end of the connector 200 is inserted into the clamping groove 301, and the locking block 311 is engaged in the locking hole 201, achieving a stable connection between the connector 200 and the support member 300. Specifically, the outer clamping plate 320 is frictionally connected to the outer surface of the connector 200, and the inner clamping plate 330 is frictionally connected to the inner surface of the connector 200. Friction connects the connector 200 and the support member 300. Simultaneously, the locking block 311 engages in the locking hole 201, further preventing the connector 200 from detaching from the support member 300. The combination of these two elements results in a more stable product structure.

[0043] In this embodiment, the locking block 311 is disposed in the middle of the inner clamping plate 330 and protrudes from the surface of the inner clamping plate 330 opposite to the pleated filter medium 100. The inner clamping plate 330 has deformation slots 302 on the left and right sides of the locking block 311. With the above structure, the locking block 311 has deformation slots 302 on the left and right sides. During the process of moving the locking block 311 toward the snap-fit ​​hole 201, the deformation slots 302 can allow the inner clamping plate 330 where the locking block 311 is located to deform. When the locking block 311 is facing the snap-fit ​​hole 201, the inner clamping plate 330 where the locking block 311 is located returns to its original position, driving the locking block 311 to be inserted into the snap-fit ​​hole 201. This makes product connection more convenient, prevents the inner clamping plate 330 where the locking block 311 is located from breaking during product installation, and improves the service life of the product.

[0044] In this embodiment, the upper surface of the inner clamping plate 330 is provided with a plurality of supporting ribs 340, which are spaced apart. When the end of the connector 200 is inserted into the clamping groove 301, the upper surface of the supporting rib 340 abuts against the surface of the connector 200 near the pleated filter medium 100. With the above structure, when the end of the connector 200 is inserted into the clamping groove 301, the inner surface of the connector 200 abuts against the surface of the supporting rib 340, and the friction between the connector 200 and the supporting rib 340 ensures that the connector 200 is stably connected to the support 300.

[0045] In this embodiment, the end of the locking block 311 is provided with a first guide surface 303. When the end of the connector 200 is inserted along the clamping groove 301, the first guide surface 303 abuts against the surface of the connector 200 near the pleated filter medium 100, allowing the locking block 311 to slide and engage in the engaging hole 201. With this structure, during the movement of the locking block 311 toward the engaging hole 201, the first guide surface 303 abuts against the end of the connector 200, which can drive the clamping plate 330 within the portion where the locking block 311 is located to deform, making it easier for the locking block 311 to slide into the engaging hole 201, facilitating installation.

[0046] In this embodiment, the end of the support rib 340 is provided with a second guide surface 304. When the end of the connector 200 is inserted along the clamping groove 301, the second guide surface 304 abuts against the surface of the connector 200 near the pleated filter medium 100, allowing the connector 200 to be smoothly inserted into the clamping groove 301. With the above structure, when the end of the connector 200 is inserted into the clamping groove 301, the inner surface of the end of the connector 200 first abuts against the second guide surface 304. Since the second guide surface 304 is an inclined surface, the end of the connector 200 slides along the second guide surface 304, making it easier for the user to insert the end of the connector 200 into the clamping groove 301 and improving assembly efficiency.

[0047] In this embodiment, the outer clamping plate 320 has a pressing notch 305 in the middle. The pressing notch 305 is opposite to the locking block 311. When the end of the connector 200 is inserted into the clamping groove 301 and the locking block 311 is engaged with the locking hole 201, the pressing notch 305 allows the user's finger to pass through to drive the locking block 311 out of the locking hole 201. With the above structure, when disassembling the product, by passing a finger through the pressing notch 305 and pressing down on the locking block 311 to disengage it from the locking hole 201, and then pulling the support 300 outward to slide the end of the connector 200 out of the clamping groove 301, the connector 200 and the support 300 can be easily separated.

[0048] In this embodiment, the inner surface of the outer clamping plate 320 is provided with a sliding groove 306, and the outer surface of the connector 200 is provided with a slide rail 210, the slide rail 210 being inserted into the connector 200. With the above structure, the slide rail 210 is inserted and slides along the slide rail 210, which limits the relative sliding direction between the connector 200 and the support 300, allowing the user to assemble the product more stably and accurately.

[0049] In this embodiment, both front and rear sides of the two connectors 200 are provided with first edge protection plates 220. The first edge protection plates 220 extend from the front and rear edges of the connectors 200 in a direction away from the outer surface of the connectors 200, and the first edge protection plates 220 cover at least part of the pleated filter media 100. With the above structure, the first edge protection plates 220 cover at least part of the pleated filter media 100, which can effectively protect the edges of the pleated filter media 100 and prevent the upper and lower edges of the pleated filter media 100 from being damaged during transportation, storage or installation of the filter device, thereby improving the service life of the product.

[0050] In this embodiment, both the front and rear sides of the two support members 300 are provided with second edge protection plates 350. The second edge protection plates 350 extend from the front and rear edges of the support members 300 in a direction away from the outer surface of the support members 300. The second edge protection plates 350 cover at least part of the pleated filter medium 100. An insertion groove 307 is formed between the inner clamping plate 330 and the second edge protection plate 350, and the first edge protection plate 220 is inserted into the insertion groove 307. With the above structure, the second edge protection plate 350 can protect the left and right edges of the pleated filter medium 100, preventing damage to the pleated filter medium 100 and affecting the filtration effect of the product; while the insertion groove 307 formed between the inner clamping plate 330 and the second edge protection plate 350 can allow the first edge protection plate 220 to be inserted, making the structure more stable after product assembly.

[0051] In this embodiment, sealing strips 340 protrude from the side surfaces of the two support members 300 facing the pleated filter medium 100. When the end of the connector 200 is inserted into the clamping groove 301, the sealing strips 340 abut against the corrugated edge 102. Through this structural arrangement, the sealing strips 340 abut against the corrugated edge 102, improving the sealing between the corrugated edge 102 and the inner surface of the support member 300, preventing gas flow along the area between the corrugated edge 102 and the inner surface of the support member 300, thus allowing gas to pass through the pleated filter medium 100 and ensuring filtration effectiveness.

[0052] In this embodiment, the pleated filter medium 100 has two opposing filter surfaces 103. A plurality of flexible strips 110 are provided between the two connectors 200. These flexible strips 110 are connected to the filter surfaces 103 to provide support for the various pleats of the filter medium. Through this structural arrangement, the flexible strips 110 can provide support for the various pleats of the filter medium. In use, the spacing between the pleats is essentially the same, ensuring uniform distribution of the filter medium in each part and improving the filtration effect.
