[0001] This utility model relates to the field of air purification technology, and in particular to an air purification system for laboratory use. Background Technology

[0002] Laboratory air purification systems are air handling equipment specifically designed for laboratory environments. They primarily use a series of technologies and devices to filter, purify, and disinfect the air inside the laboratory to remove dust, particulate matter, microorganisms, and harmful gases, providing a clean, sterile, and safe air environment for the laboratory.

[0003] A search revealed Chinese patent publication number CN222510764U, which discloses a high-efficiency air purification and filtration device for clean laboratories. The device includes a working housing with two ventilation openings. Multiple louvers are fixedly connected to each ventilation opening, and these louvers are inclined. The working housing also contains a filter chamber with two working grooves on its inner wall. A working filter element is also located within the filter chamber, and two working sliders are fixedly connected to the working filter element. These two working sliders are respectively configured to cooperate with the two working grooves. The working housing also has a working opening, which is configured to cooperate with the working filter element. An auxiliary lifting component is also provided within the filter chamber. This invention allows workers to quickly and conveniently clean, maintain, and repair the working filter element. In contrast, existing laboratory air purification systems use threads to fix the filter elements, which is cumbersome to replace and maintain, and time-consuming to disassemble. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a laboratory air purification system, which aims to improve the problem that the existing threaded fixing method is cumbersome to replace and maintain when the filter element of the laboratory air purification system is replaced, and that it is time-consuming to disassemble the filter element.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laboratory air purification system, comprising a body, wherein a mounting groove is provided on the top of the body, an activated carbon filter element is slidably connected to the inner side of the mounting groove, and fixing buckles are slidably connected to the middle of the front, rear, left and right ends of the activated carbon filter element, a spring is fixedly connected to the adjacent side of a plurality of fixing buckles, a steel wire is fixedly connected to the middle of the adjacent side of a plurality of fixing buckles, and a pull ring is fixedly connected to the end of a plurality of steel wires, and a convenient loading and unloading mechanism is installed on the rear side of the body, the convenient loading and unloading mechanism being used for quick loading and unloading of the laboratory air purification system.

[0006] The above technical solution involves pulling the pull rings on both sides of the activated carbon filter element. Pulling the two pull rings causes two steel wires fixed underneath them to move upwards. This upward movement of the two steel wires causes the corresponding fixing buckles to retract into the activated carbon filter element. Then, the activated carbon filter element is pulled out of the mounting slot on the machine body for replacement or maintenance. After that, the activated carbon filter element is reinserted into the mounting slot. Then, the two pull rings are released. At this time, multiple springs will push out the corresponding fixing buckles, thereby fixing the activated carbon filter element and the machine body.

Sliding buckles are fixedly connected to the lower middle part of the left and right ends of the front side of the fixed frame. Sliding grooves are opened on the lower middle part of the left and right ends of the rear side of the machine body. The two sliding buckles are slidably connected to the corresponding sliding grooves. A support plate is fixedly connected to the bottom of the fixed frame. Multiple threaded holes are opened at the four corners of the outer wall of the fixed frame. A screw is threadedly connected to the inner side of each of the multiple threaded holes.

[0009] The above technical solution involves fixing the fixed frame to the air outlet of the ventilation duct through multiple threaded holes and corresponding screws. Then, the two sliding grooves at the rear of the unit are aligned with the two sliding buckles fixed at the front of the fixed frame. The unit is then pressed down from top to bottom, causing the two sliding buckles to insert into the corresponding sliding grooves, thus completing the fixing of the unit. At this time, the support plate fixed under the fixed frame can provide support for the unit.

[0013] As a further description of the above technical solution:

[0014] Each of the pull rings has a rubber sleeve fixedly connected to its outer wall, and each of the rubber sleeves has anti-slip texture on its outer wall.

[0015] The above technical solution improves the grip of the pull ring by creating anti-slip textures on the rubber sleeve fixed to the outside of the pull ring.

[0016] As a further description of the above technical solution:

[0017] The support plate is fixedly connected to the left and right sides of its bottom, and two screws are threadedly connected to the middle of each of the two tripods.

[0018] The above technical solution provides support for the convenient loading and unloading mechanism by fixing the tripod with screw two.

[0022] As a further description of the above technical solution:

[0023] The inner front and rear ends of the activated carbon filter element are fixedly connected to a fixing frame, and filter screens are fixedly connected to the outer walls of the two fixing frames.

[0024] The above technical solution effectively intercepts dust and insects from entering the laboratory air purification system by fixing the filters at the front and back of the machine with a mounting bracket.

[0025] As a further description of the above technical solution:

[0026] The left and right sides of the machine body are each threaded with a plurality of screws three at equal intervals, and the outer walls of the plurality of screws three are each threaded with a lifting rod.

[0027] The above technical solution allows for the easy movement of the laboratory air purification system by fixing the lifting rod with screw three.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the pull ring moves the fixing buckle back into the activated carbon filter element via the steel wire. Then, the activated carbon filter element is pulled out from the mounting groove for replacement or maintenance.

Then, the activated carbon filter element 4 will be pulled out from the mounting groove 3 on the body 1, thus replacing or maintaining the activated carbon filter element 4. Then, the activated carbon filter element 4 will be reinserted into the mounting groove 3. After that, release the two pull rings 8. At this time, multiple springs 6 will push out the corresponding fixing buckles 5, thereby fixing the activated carbon filter element 4 and the body 1.

Then, align the two sliding grooves 203 on the back of the unit 1 with the two sliding buckles 202 fixed in front of the mounting frame 201. Then, press the unit 1 down from top to bottom so that the two sliding buckles 202 are inserted into the corresponding sliding grooves 203, thereby completing the fixation of the unit 1. At this time, the support plate 204 fixed under the mounting frame 201 can provide support for the unit 1, thus achieving the effect of quick installation and removal of the laboratory air purification system.
