Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically a detachable and modular air filter. Background Technology

[0002] An air filter is a device used to clean impurities and pollutants from the air. They are commonly used in air handling systems, air conditioning systems, car engines, and air purifiers. Air filters can remove dust, pollen, bacteria, viruses, harmful gases, and other fine particulate matter to keep the air fresh and healthy. With increasing environmental pollution, the importance of air filters is receiving more and more attention.

[0003] A detachable, modular air filter, disclosed in publication CN 220003304 U, includes a mounting frame and a filter plate. The mounting frame has a first channel on its side wall and a second channel at its bottom. First springs are fixed to the inner walls of both sides of the first channel. A connecting block is fixed to one end of each spring, and a pushing block abuts against the connecting blocks. A connecting rod is fixed to one end of each connecting block, and a limiting block is fixed to one end of each connecting rod. The limiting block engages with a fixing block. A reset rod is fixed to one end of the fixing block, passing through a sliding groove on the pushing block and extending outwards. A second spring is fitted onto the reset rod. A first transmission rod is fixed to the lower end of the pushing block. The first transmission rod is connected to a third transmission rod via a second transmission rod located in the second channel. The third transmission rod passes through the bottom inner wall of the mounting frame. This application facilitates the installation and removal of the air filter through the cooperation of components such as the third transmission rod.

[0004] However, the aforementioned utility models still have some shortcomings in use. Most filters are integrated structures, and their filtration area is determined during production, making it impossible to flexibly adjust according to the actual ventilation volume and space size. When it is necessary to expand the filtration range, a larger filter must be replaced, which is not only costly but also has poor adaptability. The filter media is prone to clogging after long-term use and requires regular cleaning or replacement. However, the filter media and frame of traditional filters are mostly fixedly connected (such as glue bonding, bolt tightening, etc.), making the disassembly process cumbersome. Especially for filters with multiple filter media, replacing a single filter media often requires disassembling the entire structure, which is time-consuming and labor-intensive, increasing maintenance costs and downtime. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a detachable, modular air filter. This solves the problem that most filters are integrated structures whose filtration area is fixed during production, making it impossible to flexibly adjust to the actual ventilation volume and space size. When an expanded filtration range is needed, a larger filter must be replaced, which is not only costly but also has poor compatibility. Furthermore, filter media is prone to clogging after prolonged use, requiring regular cleaning or replacement. However, traditional filters often use fixed connections between the filter media and frame (such as adhesive bonding or bolt fastening), making disassembly cumbersome. Especially for filters with multiple filter media, replacing a single media often requires disassembling the entire structure, which is time-consuming, labor-intensive, and increases maintenance costs and downtime.

[0006] This utility model provides the following technical solution: a detachable splicing air filter, including a support plate and a mounting frame. The surface of the support plate is provided with four mounting slots that match the mounting frames. The number of mounting frames matches the number of mounting slots. A filter plate is installed between the inner walls of each mounting frame.

[0007] Each mounting frame has a set of mounting holes on both sides, and a locking rod is slidably fitted inside each mounting hole. Each mounting slot has a set of locking grooves on both sides that match the locking rod. One end of each locking rod is fixedly connected to the inner wall of the corresponding mounting hole with a spring.

[0008] Two fixing plates are fixedly connected to one side of the support plate, and a slot is opened on the other side of the support plate, with a tensioning component installed inside the slot.

[0009] Preferred technical solution 1: The tensioning assembly includes a bidirectional lead screw rotatably installed inside the slot. Both ends of the bidirectional lead screw are threaded with lead screw sleeves. One end of each of the two lead screw sleeves is fixedly connected to a support plate. Multiple insertion rods are fixedly connected to the surfaces of the two support plates. Multiple slots matching the insertion rods are opened on the surfaces of the two fixed plates.

[0010] Preferred technical solution 2: Two sliding grooves are formed on one side wall of the hollow groove, and a slider is slidably sleeved inside each of the two sliding grooves. The two sliders are fixedly connected to the two lead screw sleeves respectively.

[0011] Preferred technical solution 3: An operating rod is rotatably connected to the surface of the support plate, one end of the operating rod extends into the interior of the slot and is fixedly connected to a first bevel gear, and a second bevel gear is fixedly sleeved on the surface of the bidirectional lead screw, with the second bevel gear meshing with the first bevel gear.

[0012] Preferred technical solution four: Each of the mounting frames has four movable slots on its surface, each movable slot is connected to a corresponding mounting hole, each latch has a lever fixedly connected to its surface, the lever can move inside the movable slot, each mounting frame has a short plate fixedly connected to its surface, each short plate has a magnet fixedly connected to its surface, and each lever is made of iron.

[0013] Preferred technical solution five: Two sets of limiting plates are fixedly connected to the inner wall of each mounting slot, a positioning rod is fixedly connected to the surface of each limiting plate, and a positioning groove matching the positioning rod is opened on the surface of each mounting frame.

[0014] Compared with the prior art, this utility model provides a detachable splicing air filter with the following advantages: When it is necessary to install the mounting frame and filter plate on the support plate, move the four levers inward, and then install the mounting frame on the four positioning rods through the positioning groove for initial positioning. Then release the four levers so that the spring force drives the locking rod to insert into the inside of the locking groove. At the same time, the lever is attracted to the magnet for further positioning and fixation, making the mounting frame more stable, and the assembly is completed.

[0015] When multiple support plates need to be assembled, insert the two fixing plates on the side of one support plate into the empty slots on the side of another support plate, and then rotate the operating lever to drive the first bevel gear and the second bevel gear to rotate, thereby driving the bidirectional lead screw to rotate. This will drive the two lead screw sleeves and the two support plates to move in opposite directions, so that the inserts on the two support plates can be inserted into the slots of the fixing plates, thus realizing the installation and fixation between the two support plates, which is convenient and quick.

[0016] This utility model allows for the rapid assembly of multiple support plates according to actual needs, facilitating the adjustment of the filtration area. It also enables the quick installation and disassembly of multiple filter plates, making them easy to clean or replace. Attached Figure Description

[0023] Example 1: A detachable splicing air filter includes a support plate 1 and a mounting frame 2. The surface of the support plate 1 is provided with four mounting grooves 3 that match the mounting frames 2. The number of mounting frames 2 matches the number of mounting grooves 3. A filter plate 4 is installed between the inner walls of each mounting frame 2.

[0024] Each mounting frame 2 has a set of mounting holes 5 on both sides. Each mounting hole 5 has a locking rod 6 slidably fitted inside. Each mounting groove 3 has a set of locking grooves 7 that match the locking rod 6 on both sides of its inner side wall. One end of each locking rod 6 is fixedly connected to the inner wall of the corresponding mounting hole 5 with a spring 8.

[0025] Two fixing plates 9 are fixedly connected to one side of the support plate 1, and a slot 10 is opened on the other side of the support plate 1. A tensioning component is installed inside the slot 10.

[0026] Example 2: The difference between this example and Example 1 is that the tensioning assembly includes a bidirectional lead screw 11 rotatably installed inside the slot 10. Both ends of the bidirectional lead screw 11 are threaded with lead screw sleeves 12. One end of each lead screw sleeve 12 is fixedly connected to a support plate 13. Multiple insertion rods 14 are fixedly connected to the surfaces of the two support plates 13. Multiple slots 15 matching the insertion rods 14 are opened on the surfaces of the two fixing plates 9 to facilitate the connection between the multiple support plates 1.

[0027] Example 3: The difference between this example and Example 1 is that two sliding grooves 16 are opened on one side wall of the hollow groove 10, and sliders 17 are slidably sleeved inside the two sliding grooves 16. The two sliders 17 are fixedly connected to the two lead screw sleeves 12 respectively.

[0028] Example 4: The difference between this example and Example 1 is that the surface of the support plate 1 is rotatably connected to the operating rod 18, one end of the operating rod 18 extends into the interior of the slot 10 and is fixedly connected to the first bevel gear 19, and the surface of the bidirectional lead screw 11 is fixedly sleeved with the second bevel gear 20, and the second bevel gear 20 and the first bevel gear 19 mesh with each other, which facilitates operation by the user.

[0029] Example 5: The difference between this example and Example 1 is that each mounting frame 2 has four movable slots 21 on its surface, each movable slot 21 is connected to a corresponding mounting hole 5, each lever 6 has a lever 22 fixedly connected to its surface, the lever 22 can move inside the movable slot 21, each mounting frame 2 has a short plate 23 fixedly connected to its surface, each short plate 23 has a magnet 24 fixedly connected to its surface, and each lever 22 is made of iron, which makes it convenient for users to install the mounting frame 2 and filter plate 4 on the support plate 1.

[0030] Example 6: The difference between this example and Example 1 is that each mounting slot 3 has two sets of limiting plates 25 fixedly connected to its inner wall, each limiting plate 25 has a positioning rod 26 fixedly connected to its surface, and each mounting frame 2 has a positioning groove 27 that matches the positioning rod 26 on its surface, which facilitates the initial positioning of the mounting frame 2 and facilitates subsequent installation.

[0031] In summary, when the mounting frame 2 and filter plate 4 need to be installed on the support plate 1, the four levers 22 are moved inward, and the mounting frame 2 is initially positioned on the four positioning rods 26 through the positioning groove 27. Then, the four levers 22 are released so that the locking rod 6 is inserted into the slot 7 under the elastic force of the spring 8. At the same time, the levers 22 are attracted to the magnet 24 for further positioning and fixation, making the mounting frame 2 more stable, and the assembly is completed.

[0032] When multiple support plates 1 need to be assembled, insert the two fixing plates 9 on the side of one support plate 1 into the empty slot 10 on the side of another support plate 1, and then rotate the operating lever 18 to drive the first bevel gear 19 and the second bevel gear 20 to rotate, thereby driving the bidirectional lead screw 11 to rotate, which can drive the two lead screw sleeves 12 and the two support plates 13 to move in opposite directions, so that the insert rods 14 on the two support plates 13 are inserted into the slots 15 of the fixing plates 9, thereby realizing the installation and fixation between the two support plates 1, which is convenient and quick.

[0033] In use, this utility model allows for the rapid assembly of multiple support plates 1 according to actual needs, facilitating the adjustment of the filtration area. It also allows for the rapid installation and disassembly of multiple filter plates 4, making them easy to clean or replace.
