Abstract
Description
Technical Field
[0001] This utility model belongs to the field of air filtration technology, specifically relating to a modular, quick-assembly air filter. Background Technology
[0002] Air filters are mainly used to remove particulate matter, microorganisms, and gaseous pollutants from the air to improve indoor air quality. They contain different filters, each with different filtration functions depending on the filter type. Therefore, multiple filters need to be integrated to achieve the best filtration effect. The filtration effect of the filters will initially decrease over time, so the filters need to be replaced regularly.
[0003] However, traditional air filters mostly use a fixed structure, and replacing the filter requires disassembling the outer shell layer by layer, which is complicated and time-consuming. Utility Model Content
[0004] The purpose of this invention is to provide a modular, quick-assembly air filter that can synchronously control the opening and closing of various parts of the device through a linkage design. This makes it more suitable for scenarios that require frequent filter replacement or adjustment of the number of filter layers, thereby improving assembly efficiency.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A modular, quick-assembly air filter includes an air inlet base, a plurality of filter mechanisms are mounted on the top of the air inlet base, and an air outlet cover is mounted above the topmost filter mechanism. The air inlet base is connected to the filter mechanism, the filter mechanism is connected to the filter mechanism, and the air outlet cover is connected to the filter mechanism via a linkage assembly.
[0007] The filtration mechanism includes a quick-release frame, a filter mounting bracket is slidably installed at one end of the quick-release frame, and connecting rod mounting slots are provided on both sides of the air inlet base, air outlet top cover and quick-release frame. The connecting rod assembly is installed in the connecting rod mounting slot, and a limit guide slot is also provided inside the connecting rod mounting slot.
[0008] The linkage assembly includes a first link and a second link. The middle parts of the first link and the second link are rotatably connected by a pin. In two adjacent linkage assemblies, the lower first link is rotatably connected to the upper second link, and the lower second link is rotatably connected to the upper first link. The first link and the second link in the two linkage assemblies are rotatably connected by a sliding post, which is slidably installed in a limiting guide groove.
[0009] Furthermore, each of the four corners of the top of the air outlet cover is rotatably connected to a rotating block, and a rotating rod is fixed to the bottom of the rotating block. Several locking blocks are provided on one side of the rotating rod. Rotating rod grooves are provided at the four corners of the air inlet base, the air outlet cover, and the quick-release frame. The rotating rod grooves allow the rotating rod and the locking blocks to slide. A fan-shaped locking groove is also provided in the middle of the rotating rod groove. The fan-shaped locking groove is used for the rotation locking of the locking blocks.
[0010] Furthermore, a ventilation duct is provided in the middle of the quick-installation frame, and two top frame clamps are provided on the inner wall of the ventilation duct. The filter mounting bracket is slidably installed between the two top frame clamps, and a detachable filter assembly is installed on the top of the filter mounting bracket. When the filter mounting bracket is installed between the two top frame clamps, the bottom of the top frame clamp is pressed against the outer side of the top of the filter assembly.
[0011] Furthermore, a mounting push plate is fixed to one end of the filter mounting bracket, a mounting insert plate is fixed to the top of one end of the air inlet base and the top of the mounting push plate, and mounting grooves adapted to the mounting insert plates are opened at the bottom of one end of the air outlet cover and the bottom of the mounting push plate.
[0012] Furthermore, a fan is installed inside the air inlet base, and several air vents are opened on the outer side of both the air inlet base and the air outlet top cover, with large particle filters installed at the air vents.
[0013] Furthermore, the air inlet base and the top of the quick-release frame are provided with two sealing rings.
[0014] The technical effects achieved by this utility model are as follows:
[0015] This utility model, through the linkage design of the linkage assembly, only needs to control the lifting and lowering of the air outlet top cover to simultaneously control the opening or closing of all filter mechanisms. This mechanical linkage mechanism significantly reduces the tedious steps of adjusting layer by layer, and is especially suitable for scenarios that require frequent replacement of filter screens or adjustment of the number of filter layers, thus improving assembly efficiency.
[0016] This utility model adopts a sliding design for the filter mounting bracket, combined with the pressing and fixing of the top frame clamping plate, which allows for quick pull-out replacement of the filter assembly, making it easier to disassemble and replace the filter assembly.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1 to 5 As shown, a modular quick-assembly air filter includes an air inlet base 1, a plurality of filter mechanisms 3 are installed on the top of the air inlet base 1, and an air outlet cover 2 is installed above the topmost filter mechanism 3. The air inlet base 1 is connected to the filter mechanism 3, the filter mechanism 3 is connected to the filter mechanism 3, and the air outlet cover 2 is connected to the filter mechanism 3 by a connecting rod assembly 4.
[0026] The air inlet base 1 is equipped with a fan, and the air inlet base 1 and the air outlet top cover 2 are both provided with several air vents on their outer sides, and large particle filters are installed at the air vents.
[0027] The filter mechanism 3 includes a quick-release frame 31, a filter mounting bracket 36 is slidably installed at one end of the quick-release frame 31, and connecting rod mounting grooves 32 are provided on both sides of the air inlet base 1, the air outlet top cover 2 and the quick-release frame 31. The connecting rod assembly 4 is installed in the connecting rod mounting groove 32, and a limit guide groove is also provided inside the connecting rod mounting groove 32.
[0028] The linkage assembly 4 includes a first linkage 41 and a second linkage 42. The middle parts of the first linkage 41 and the second linkage 42 are rotatably connected by a pin. In two adjacent linkage assemblies 4, the lower first linkage 41 is rotatably connected to the upper second linkage 42, and the lower second linkage 42 is rotatably connected to the upper first linkage 41. The first linkage 41 and the second linkage 42 in the two linkage assemblies 4 are rotatably connected by a sliding post 43, which is slidably installed in a limiting guide groove.
[0029] In the above-mentioned process, when in use, the fan drives the outside air to enter the air inlet base 1 through the air inlet base 1, and the air is initially filtered by the large particle filter screen. The air is then driven by the fan to pass through multiple stacked filter mechanisms 3 in sequence. After the air is filtered, it is discharged through the air outlet on the top cover 2 to complete the air purification.
[0030] Furthermore, when assembly or disassembly is required, moving the air outlet cover 2 upward will cause the connecting rod assembly 4 between the air outlet cover 2 and the filter mechanism 3 to deform as a whole. As the connecting rod assembly 4 deforms, it will drive the sliding column 43 connected to the first connecting rod 41 and the second connecting rod 42 to slide in the limiting guide groove, and simultaneously drive the other connecting rod assemblies 4 connected to it to deform synchronously, thereby raising the overall height of the device and allowing the filter mechanism 3 to be unfolded. With a single operation, all filter mechanisms 3 can be controlled to be in the unfolded or closed state, which can significantly improve the assembly efficiency and is suitable for scenarios that require frequent filter replacement or adjustment of the number of filter layers.
[0031] Please refer to the following: Figure 2 , Figure 3 and Figure 4 As shown, each of the four corners of the top of the air outlet cover 2 is rotatably connected to a rotating block 21. A rotating rod 22 is fixed to the bottom of the rotating block 21. Several locking blocks 23 are provided on one side of the rotating rod 22. Rotating rod grooves 33 are provided at the four corners of the air inlet base 1, the air outlet cover 2, and the quick-install frame 31. The rotating rod grooves 33 allow the rotating rod 22 and the locking blocks 23 to slide. A fan-shaped locking groove 34 is also provided in the middle of the rotating rod groove 33. The fan-shaped locking groove 34 is used for the rotation locking of the locking block 23.
[0032] In the above description, when the air inlet base 1, the air outlet top cover 2, and the filter mechanism 3 are in the closed state, the locking block 23 is located in the fan-shaped locking groove 34. At this time, the air inlet base 1, the air outlet top cover 2, and the filter mechanism 3 are locked. When it is necessary to unfold the air inlet base 1, the air outlet top cover 2, and the filter mechanism 3, by rotating each rotating block 21, the rotating rod 22 is rotated, causing each locking block 23 to move into the rotating rod slide groove 33. At this time, pushing the air outlet top cover 2 upward can drive several filter mechanisms 3 to unfold synchronously. After merging, rotating the rotating block 21 causes the locking block 23 to enter the fan-shaped locking groove 34, which can re-lock the air inlet base 1, the air outlet top cover 2, and the filter mechanism 3, avoiding gaps in the connection between the air inlet base 1, the air outlet top cover 2, and the filter mechanism 3 due to the impact force generated by the collision, resulting in incomplete sealing.
[0033] Please refer to it again. Figure 3 As shown, a ventilation duct is provided in the middle of the quick-installation frame 31. Two top frame clamps 35 are provided on the inner wall of the ventilation duct. The filter mounting bracket 36 is slidably installed between the two top frame clamps 35. A detachable filter assembly 38 is installed on the top of the filter mounting bracket 36. When the filter mounting bracket 36 is installed between the two top frame clamps 35, the bottom of the top frame clamps 35 presses against the outer side of the top of the filter assembly 38.
[0034] In the above-described manner, when the filter mechanism 3 is in the unfolded state, the filter mounting bracket 36 can be slid to assemble and disassemble the filter mounting bracket 36. At the same time, the filter assembly 38 is placed directly on top of the filter mounting bracket 36. When replacing the filter assembly 38, the filter assembly 38 can be removed by gently pushing it from the bottom of the filter mounting bracket 36, making it convenient to replace the filter assembly 38. When the filter assembly 38 is installed on the filter mounting bracket 36, the upper surface of the outer frame of the filter assembly 38 is flush with the upper surface of the filter mounting bracket 36. When installed in the quick-installation frame 31, the filter assembly 38 is pressed into the filter mounting bracket 36 by the top frame clamp 35, which can maintain a stable installation and prevent the installation from loosening due to air pressure during the air filtration process.
[0035] Please refer to it again. Figure 3 As shown, a mounting push plate 37 is fixed to one end of the filter mounting bracket 36, and a mounting insert plate 39 is fixed to the top of one end of the air inlet base 1 and the top of the mounting push plate 37. A mounting groove adapted to the mounting insert plate 39 is opened at the bottom of one end of the air outlet top cover 2 and the bottom of the mounting push plate 37.
[0036] As described above, the mounting push plate 37 installed at one end of the filter mounting bracket 36 facilitates the disassembly and assembly of the filter mounting bracket 36. At the same time, the mounting insert plate 39 and the mounting groove can also be fitted together after the air inlet base 1, the air outlet top cover 2 and the filter mechanism 3 are combined to fix the position of the mounting push plate 37.
[0037] Two sealing rings are provided on the top of the air inlet base 1 and the quick-release frame 31;
[0038] The sealing rings provided above can provide a better sealing effect after the air inlet base 1, the air outlet top cover 2 and the quick-release frame 31 are combined, so as to avoid air leakage during the air filtration process and ensure the air filtration effect.
[0039] The working principle of this utility model is as follows: When different filter screen components 38 need to be assembled, the rotating block 21 drives the rotating rod 22 and the locking block 23 to rotate, so that the locking block 23 rotates out of the fan-shaped locking groove 34 and is located at the rotating rod slide groove 33. At this time, the air outlet top cover 2 is lifted upward, and through the linkage of multiple connecting rod components 4, several filter mechanisms 3 are simultaneously lifted. Then, the filter screen mounting bracket 36 located in the quick-installation frame 31 is pulled out, the matching filter screen component 38 is placed in the middle of the filter screen mounting bracket 36, and the filter screen mounting bracket 36 is slid back in. Inside the quick-install frame 31, the filter assembly 38 is fixed by the pressure of the top frame clamp 35. After all the compatible filter assemblies 38 are installed, pressing down the air outlet top cover 2 can drive several filter mechanisms 3 to descend synchronously, so that the air inlet base 1, the air outlet top cover 2 and the filter mechanism 3 are closed. Rotating the screw block 21 drives the locking block 23 to re-screw into the fan-shaped locking groove 34 to complete the fixation. The simple operation can synchronously control the filter mechanism 3 to unfold or merge, which can significantly improve the assembly efficiency and is suitable for scenarios where filters are frequently replaced or the number of layers is adjusted.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
