Description

Technical Field

[0001] This utility model relates to the field of air purification device technology, specifically to an air purification device for experimental analysis instruments with a quickly replaceable filter element. Background Technology

[0002] In laboratories, analytical instruments have high requirements for air quality. Dust and impurities in the air can affect the accuracy and lifespan of the instruments, so air purification devices are often installed. However, existing air purification devices for analytical instruments have some shortcomings. As a core component, the filter element needs to be replaced regularly to ensure purification effectiveness.

[0003] However, when replacing the filters in traditional air purifiers, a large amount of dust adsorbed on the filters can easily fall off. This dust may contain various pollutants, which can contaminate the laboratory environment, interfere with experimental results, and increase laboratory cleaning costs and time. Moreover, the filter replacement operation of some air purifiers is complicated, requiring the use of tools to disassemble multiple parts, which is time-consuming and labor-intensive, affecting the normal progress of experiments. Utility Model Content

[0004] In view of the problems existing in the air purification devices of the above-mentioned experimental analysis instruments, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide an air purification device for experimental analytical instruments with a quickly replaceable filter element, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An air purification device for experimental analytical instruments with a quick-replaceable filter element includes a purification chamber and an exhaust fan. The purification chamber has an air outlet at its top, and the exhaust fan is fixedly installed above the air outlet. Multiple air inlets are located on both sides of the lower end of the purification chamber. A through groove is formed on one side of the middle of the purification chamber, and a filter element body is inserted into the through groove. A first mounting plate is fixedly installed at one outer end of the filter element body, abutting against the outer wall of the purification chamber. A fixed plate is fixedly installed at the lower end of the filter element body on the side away from the through groove. A movable plate is installed on the side of the fixed plate near the through groove. A folding baffle is fixedly installed between the movable plate and the fixed plate. Sliding rods are fixedly installed at both ends of the movable plate on the side away from the fixed plate. One end of each sliding rod extends to the outside of the first mounting plate. A second mounting plate is fixedly installed between the outer ends of the two sliding rods. A limiting mechanism is provided on the outer wall of the purification chamber, above the through groove, to restrict the movement of the first and second mounting plates.

[0008] Preferably, the limiting mechanism includes a rotating rod and a Z-shaped plate. A U-shaped plate is fixedly installed on the outer wall of the purification box and on the upper side of the through groove. The rotating rod is rotatably sleeved on the inner side of the U-shaped plate. The Z-shaped plate is fixedly sleeved on the rod wall of the rotating rod. The two ends of the Z-shaped plate respectively abut against the side of the corresponding first mounting plate and second mounting plate away from the purification box. Threaded rods are threaded into the interior of both ends of the U-shaped plate. The threaded rods abut against the side of the Z-shaped plate away from the purification box.

[0009] Preferably, a knob is fixedly sleeved on one outer end of the threaded rod.

[0010] Preferably, both the purification chamber and the filter element body have rectangular cross-sections, and the outer wall of the filter element body abuts against the inner wall of the purification chamber.

[0011] Preferably, the outer wall of the filter element body is provided with a sealing gasket.

[0012] Preferably, the surface of the folding baffle is coated with a hydrophobic coating.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model allows the Z-shaped plate to be separated from the threaded rods on both sides by rotating the threaded rods, thereby releasing the restriction on the Z-shaped plate. Then, the Z-shaped plate is rotated around the rotating rod as an axis to separate the Z-shaped plate from the first mounting plate and the second mounting plate, thereby releasing the restriction on the filter element body and making it convenient and time-saving to replace the filter element body.

[0015] 2. In this utility model, after releasing the limiting position of the first mounting plate and the second mounting plate, the second mounting plate is pulled first, causing the movable plate to move away from the fixed plate, thereby causing the folding baffle to unfold and block the bottom of the filter element body. Then, the second mounting plate is pulled to pull the filter element body out of the through groove. Since the folding baffle blocks the bottom of the body, it can effectively prevent dust at the bottom of the filter element body from falling to the ground. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses an air purification device for experimental analysis instruments with a quickly replaceable filter element.

[0024] Reference Figure 1-3 An air purification device for experimental analytical instruments with a quick-replaceable filter element includes a purification chamber 1 and an exhaust fan 2. The purification chamber 1 has an air outlet at its top, and the exhaust fan 2 is fixedly installed above the air outlet. Multiple air inlets are located on both sides of the lower end of the purification chamber 1. A through groove is formed on one side of the middle of the purification chamber 1, and a filter element body 4 is inserted into the through groove. A first mounting plate 3 is fixedly installed on one outer end of the filter element body 4, abutting against the outer wall of the purification chamber 1. A fixing plate 11 is fixedly installed on the lower end of the filter element body 4 on the side away from the through groove. A movable plate 13 is provided on the side near the through groove. A folding baffle 12 is fixedly provided between the movable plate 13 and the fixed plate 11. The surface of the folding baffle 12 is coated with a hydrophobic coating to facilitate cleaning. Slide rods 10 are fixedly provided at both ends on the side of the movable plate 13 away from the fixed plate 11. One end of the slide rod 10 extends to the outside of the first mounting plate 3. A second mounting plate 5 is fixedly provided between the outer ends of the two slide rods 10. A limiting mechanism is provided on the outer wall of the purification box 1 and on the upper side of the through groove to restrict the movement of the first mounting plate 3 and the second mounting plate 5.

[0025] Reference Figure 1-3 The limiting mechanism includes a rotating rod 8 and a Z-shaped plate 6. A U-shaped plate 7 is fixedly installed on the outer wall of the purification box 1 and on the upper side of the through groove. The rotating rod 8 is rotatably sleeved on the inner side of the U-shaped plate 7. The Z-shaped plate 6 is fixedly sleeved on the rod wall of the rotating rod 8. The two ends of the Z-shaped plate 6 respectively abut against the side of the corresponding first mounting plate 3 and second mounting plate 5 away from the purification box 1. Threaded rods 9 are threaded inside both ends of the U-shaped plate 7. The threaded rods 9 abut against the side of the Z-shaped plate 6 away from the purification box 1. A knob is fixedly sleeved on the outer end of the threaded rod 9 to facilitate rotation of the threaded rod 9.

[0026] Reference Figure 1-3 Both the purification chamber 1 and the filter element body 4 have rectangular cross-sections. The outer wall of the filter element body 4 abuts against the inner wall of the purification chamber 1, so that the filter element body 4 cannot rotate relative to the purification chamber 1, thus it can be stably installed in the purification chamber 1. The outer wall of the filter element body 4 is provided with a sealing gasket to improve the sealing between the filter element body 4 and the purification chamber 1.

[0027] In this utility model, when the air purification device is in use, the exhaust fan 2 is started, and laboratory air enters from the air inlets on both sides of the lower end of the purification box 1. After being filtered by the filter body 4, the clean air is discharged from the top air outlet, thus achieving air purification.

[0028] When the filter element body 4 needs to be replaced, first turn the threaded rods 9 on both sides by turning the knob to separate the threaded rods 9 from the Z-shaped plate 6 and release the fixation of the Z-shaped plate 6. Then, rotate the Z-shaped plate 6 around the rotating rod 8 as the axis so that its two ends disengage from the first mounting plate 3 and the second mounting plate 5 and release the restriction on the filter element body 4.

[0029] At this time, the second mounting plate 5 is slowly pulled outwards by hand, and the slide bar 10 slides along the through hole of the first mounting plate 3, driving the movable plate 13 to move away from the fixed plate 11. The folding baffle 12 between the movable plate 13 and the fixed plate 11 gradually unfolds until it completely covers the area under the filter element body 4. After the folding baffle 12 unfolds, the second mounting plate 5 is pulled outwards by hand, and the first mounting plate 3 moves outwards synchronously with the filter element body 4, pulling the filter element body 4 out of the through groove. During this process, the folding baffle 12 effectively shields the bottom of the filter element body 4, preventing the adsorbed dust from falling and contaminating the laboratory environment.

[0030] When replacing the new filter element body 4, first fold the folding baffle 12 back to its original position (push the second mounting plate 5 to bring the movable plate 13 close to the fixed plate 11), then align the filter element body 4 with the through groove and insert it into the purification box 1, ensuring that the first mounting plate 3 is in close contact with the outer wall of the purification box 1, and finally rotate the Z-shaped plate 6 so that its two ends are in contact with the first mounting plate 3 and the second mounting plate 5 respectively, and rotate the threaded rod 9 in the opposite direction to tighten the Z-shaped plate 6, thus completing the fixed installation of the filter element body 4;

[0031] The sealing gasket on the outer wall of the filter body 4 enhances the fit and seal with the inner wall of the purification chamber 1, preventing unfiltered air from flowing directly; the hydrophobic coating on the surface of the folding baffle 12 facilitates later cleaning and prevents dust adhesion. The entire replacement process requires no tools, is easy to operate, and can effectively avoid dust pollution, making it suitable for laboratory scenarios with high requirements for environmental cleanliness.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
