Description

Technical Field

[0001] This utility model relates to the field of nonwoven filter technology, specifically a multifunctional nonwoven filter structure. Background Technology

[0002] Non-woven fabrics used for air filtration are usually needle-punched. These non-woven fabrics have the advantages of uniform folding, high strength, and good stability. They can purify dust, soot, allergens, and harmful gases in the air. The filter non-woven fabric uses polyester staple fiber, which can ensure air intake and breathability, and can also filter larger flying particles in the air.

[0003] In the prior art, such as the non-woven air filter structure disclosed in Chinese Utility Model Patent Publication No. CN222752780U, a T-shaped rod at the upper end of the support frame is movably inserted into the limiting track, which facilitates effective and firm support of the support frame. The locking block on the outside of the support frame engages with the locking groove on the outside of the support rod, which facilitates the locking and fixing of the locking components. The support frame is sleeved on the inner side of the concave support block, which facilitates the support effect of the support frame, thereby locking and fixing the support frame and the non-woven bag, which facilitates the stable installation of the non-woven bag. Furthermore, the rectangular magnetic strips on the outside of the mounting plate and the rectangular magnetic strips in the rectangular frame groove on the outside of the shell are magnetically attracted to each other, which facilitates the magnetic fixing of the mounting plate, and thus allows for quick and easy detachable installation of multiple non-woven bags.

[0004] However, in the aforementioned prior art, since the non-woven bag is triangular and the outer shell is square, there will be a large number of gaps between the non-woven bag and the outer shell, which can easily allow a large amount of gas to pass through the gaps, thus affecting gas filtration. Therefore, it is necessary to provide a multifunctional non-woven filter structure. Utility Model Content

[0005] One of the technical problems to be solved by this application is that, since the non-woven bag is triangular and the outer shell is square, there will be a lot of gaps between the non-woven bag and the outer shell, which makes it easy for a lot of gas to pass through the gaps, thus affecting gas filtration.

[0006] To solve the above technical problems, this application provides a multifunctional nonwoven filter structure, including: a filter box and a disassembly unit fixedly installed at the bottom of the filter box;

[0007] A baffle unit is plugged into and installed on one side of the filter box;

[0008] A fixing unit that is fixedly installed on the surface of the filter box;

[0009] The disassembly unit includes a motor installed inside the filter box, a threaded rod installed at the output end of the motor, a threaded cylinder threaded to the surface of the threaded rod, a first slider connected to one end of the threaded cylinder, a groove formed on the surface of the filter box, one end of the first slider passing through the groove and connected to a plate, the first slider and the groove being slidably connected, a mounting shell welded to the surface of the plate, a slide rail installed inside the filter box, a second slider slidably installed on the surface of the slide rail, one end of the second slider being connected to the plate, a second insert rod inserted into the surface of the mounting shell, and a non-woven bag inserted inside the mounting shell.

[0010] As a further optimization, there are two slide rails and two second sliders, which are symmetrically installed at the bottom inside the filter box.

[0011] As a further optimization, there are multiple mounting shells, which are linearly arranged and welded to the surface of the plate. All of the mounting shells are connected by a second insert rod, and the non-woven bag is fixed inside the mounting shell by the second insert rod.

[0012] As a further optimization, the baffle unit includes a baffle, an exhaust pipe welded to the surface of the baffle, and inserts welded at equal intervals on the surface of the baffle, with a first insert rod inserted into the surface of each insert.

[0013] As a further optimization, the fixing unit includes a cylinder, and a fixing plate is mounted on one end of the cylinder.

[0014] As a further optimization, casters are installed at the four corners of the bottom of the filter box, and inserts are installed on the surface of the filter box at equal intervals. The inserts and inserts are compatible with each other. An air inlet is installed on one side of the filter box, and multiple filter holes are arranged in a circular array on the surface of the air inlet.

[0015] As a further optimization, the nonwoven bag includes an outer nonwoven layer and an inner nonwoven layer, with an antibacterial layer, a bactericidal layer, an activated carbon particle layer, and a meltblown fabric layer sandwiched between the outer and inner nonwoven layers.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. The non-woven bag on the surface of the plate moves inside the filter box through the motor and threaded rod, threaded cylinder and slide groove, first slider and slide rail and second slider. The non-woven bag can be moved out or in the filter box. The non-woven bag can be installed and removed through the mounting shell and second insert rod, which facilitates the cleaning and replacement of the non-woven bag and improves the practicality of the device.

[0018] 2. The filter box, mounting shell, and non-woven bag are all square, which minimizes the gaps between the filter box and the non-woven fabric, effectively preventing a large amount of gas from escaping through the gaps and improving the filtration effect. By setting up a baffle unit, the baffle, insert block, insert shell, and first insert rod facilitate the disassembly of the baffle and the maintenance of the filter box, thus improving the convenience of this device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6As shown, this utility model provides a technical solution: a multifunctional non-woven fabric filter structure, including a filter box 1, a disassembly unit fixedly installed at the bottom of the filter box 1, a baffle unit inserted and installed on one side of the filter box 1, and a fixing unit fixedly installed on the surface of the filter box 1; the disassembly unit includes a motor 5 disposed inside the filter box 1, a threaded rod 501 installed at the output end of the motor 5, a threaded cylinder 502 threadedly connected to the surface of the threaded rod 501, a first slider 504 connected to one end of the threaded cylinder 502, and a section opened in... The filter box 1 has a groove 503 on its surface. One end of the first slider 504 passes through the groove 503 and is connected to the plate 507. The first slider 504 and the groove 503 are slidably connected. The mounting shell 508 is welded to the surface of the plate 507. The slide rail 505 is installed inside the filter box 1. The second slider 506 is slidably installed on the surface of the slide rail 505. One end of the second slider 506 is connected to the plate 507. The second insert rod 509 is inserted into the surface of the mounting shell 508. The non-woven bag 6 is inserted inside the mounting shell 508.

[0028] like Figures 3 to 5 As shown, there are two slide rails 505 and two second sliders 506, which are symmetrically installed at the bottom inside the filter box 1. There are multiple mounting shells 508, which are linearly arranged and welded to the surface of the plate 507. Multiple mounting shells 508 are inserted through the second insert rod 509. The non-woven bag 6 is fixed inside the mounting shell 508 through the second insert rod 509.

[0029] Through the above technical solution, the non-woven bag 6 is inserted into the inside of the mounting shell 508, and the non-woven bag 6 is fixed to the surface of the mounting shell 508 by the second insertion rod 509. The motor 5 drives the threaded rod 501 to rotate, causing the threaded cylinder 502 to move. In conjunction with the sliding groove 503 and the first slider 504, and the slide rail 505 and the second slider 506, the plate 507 is moved to the inside of the filter box 1, thereby installing the non-woven bag 6 inside the filter box 1.

[0030] For example Figures 1 to 2 As shown, the baffle unit includes a baffle 4, an exhaust pipe 401 is welded to the surface of the baffle 4, and insert blocks 402 are welded to the surface of the baffle 4 at equal intervals. A first insert rod 403 is inserted into the surface of the insert blocks 402.

[0031] By using the above technical solution, the insert block 402 on the surface of the baffle 4 is inserted into the interior of the insert shell 103, and then the insert block 402 is fixed together with the insert shell 103 by the first insert rod 403, so that the baffle 4 is fixedly installed at one end of the filter box 1.

[0032] like Figures 2 to 4As shown, the fixing unit includes a cylinder 3, a fixing plate 301 is installed at one end of the cylinder 3, casters 2 are installed at the four corners of the bottom of the filter box 1, insert shells 103 are installed at equal intervals on the surface of the filter box 1, the insert shells 103 are adapted to the insert blocks 402, an air inlet cylinder 101 is installed on one side of the filter box 1, and multiple filter holes 102 are opened in a circular array on the surface of the air inlet cylinder 101.

[0033] The above technical solution allows the device to be moved freely by setting universal wheels 2, and the fixed plate is moved by a cylinder to contact the ground and fix it in place, thus preventing the device from moving during use.

[0034] like Figure 5 and Figure 6 As shown, the nonwoven bag 6 includes an outer nonwoven fabric layer 601 and an inner nonwoven fabric layer 606, with an antibacterial layer 602, a bactericidal layer 603, an activated carbon particle layer 604, and a meltblown fabric layer 605 sandwiched between the outer nonwoven fabric layer 601 and the inner nonwoven fabric layer 606.

[0035] Through the above technical solution, the non-woven bag 6 uses an inner non-woven fabric layer 606 to initially filter dust and impurities, then uses a meltblown fabric layer 605 to filter finer particulate dust, and then uses an activated carbon granule layer 604, a bactericidal layer 603 made of bamboo charcoal fiber material, and an antibacterial layer 602 made of antibacterial filter cotton material to purify odors and inhibit bacteria and kill bacteria, thereby improving the air filtration and purification effect. Finally, the outer non-woven fabric layer 601 performs a final filtration, effectively performing multiple filtrations of the air.

[0036] All electrical devices in this utility model are powered by an external power source. The working principle and usage process are as follows: The non-woven bag 6 is inserted into the mounting shell 508. The second insert rod 509 passes through the non-woven bag 6 and the mounting shell 508, fixing the non-woven bag 6 to the surface of the mounting shell 508. The motor 5 drives the threaded rod 501 to rotate, causing the threaded cylinder 502 to move. This, in conjunction with the sliding groove 503 and the first slider 504, and the slide rail 505 and the second slider 506, moves the plate 507, placing it inside the filter box 1. The non-woven bag 6 is then installed inside the filter box 1. The insert block 402 on the surface of the baffle 4 is inserted into the insert shell 103, and then the first insert rod 403 fixes the insert block 402 to the insert shell 103. The baffle 4 is then fixedly installed at one end of the filter box 1. The air to be filtered enters the filter box 1 through the air inlet cylinder 101 and then passes through the filter holes 102, allowing for air purification. The air is filtered to prevent large impurities from entering the filter box 1. After being filtered by the non-woven bag 6, the non-woven bag 6 performs preliminary filtration of dust and impurities through the inner non-woven fabric layer 606, and then filters finer particulate dust through the meltblown fabric layer 605. Subsequently, the air undergoes odor purification and antibacterial sterilization through the activated carbon granule layer 604, the bactericidal layer 603 made of bamboo charcoal fiber material, and the antibacterial filter cotton material antibacterial layer 602, improving the air filtration and purification effect. Finally, the air undergoes a final filtration through the outer non-woven fabric layer 601, effectively performing multiple filtrations before being discharged through the exhaust pipe 401. The filter box 1, the mounting shell 508, and the non-woven bag 6 are all square, resulting in small gaps between the filter box 1 and the non-woven bag 6, effectively preventing a large amount of air from escaping through the gaps and improving the filtration effect.
