Description

A replaceable modular cleanroom filter air outlet assembly Technical Field

[0001] This utility model relates to the field of cleanroom technology, and in particular to a replaceable modular cleanroom filter air outlet assembly. Background Technology

[0002] Cleanroom air vents are core components for maintaining air cleanliness in fields such as semiconductors and biomedicine. Their filter elements need to be replaced regularly to ensure filtration efficiency. Traditional air vents mostly use bolt-fastened or clip-on fixing structures, which have the following drawbacks:

[0003] 1. Low maintenance efficiency: Disassembling the filter element requires special tools to loosen the bolts one by one or pry open the clips, which is time-consuming and can easily damage the sealing strip;

[0004] 2. Poor structural reliability: Traditional snap-fit ​​designs are prone to fatigue and breakage under long-term vibration, resulting in gaps between the filter element and the housing, which may lead to leakage risks. Therefore, we propose a replaceable modular cleanroom filter air outlet assembly to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a replaceable modular cleanroom filter air outlet assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A replaceable modular cleanroom filter air outlet assembly includes: an outer shell, a top cover, and a filter element. A support plate is fixedly installed inside the outer shell. A fixing frame is fixedly installed on the top of the support plate. A positioning frame is fixedly installed on the bottom of the top cover. The positioning frame and the filter element are both set within the fixing frame. Positioning mechanisms are provided on both sides of the fixing frame. Each positioning mechanism includes: a positioning seat and a rotating plate. A connecting shaft is fixedly installed inside the rotating plate. A connecting disc is fixedly installed at one end of the connecting shaft. The connecting disc is rotatably installed on one side of the positioning seat. Two fixing plates are fixedly installed on the inner walls of both sides of the outer shell. Grooves are formed on the side of the two fixing plates on the same side that are close to each other. The rotating plate movably abuts against the side wall of the corresponding groove. Positioning slots are formed on both sides of the positioning frame. The positioning plate is movably engaged in the corresponding positioning slot.

[0008] Preferably, the positioning seat is slidably sleeved on the outside of the corresponding fixed plate, a limit ring and a torsion spring are fixedly installed on one side of the positioning seat, the limit ring is movably abutting against the outside of the connecting plate, and the other end of the torsion spring is fixedly connected to the corresponding rotating plate.

[0009] Preferably, a connecting spring is fixedly installed on the other side of the rotating plate, and the other end of the connecting spring is fixedly installed on the side wall of the outer casing.

[0010] Preferably, both sides of the outer casing are provided with round holes, and the other end of the connecting shaft passes through the round holes and is fixedly installed with a pull plate, and a handle is fixedly installed inside the pull plate.

[0011] Preferably, the top of the top plate has a through hole, and the front side of the top plate is connected to a side air inlet pipe, with a flange fixedly installed at one end of the side air inlet pipe.

[0012] Preferably, mounting ears are fixedly installed at the four bottom corners of the outer casing.

[0013] In this utility model, a replaceable modular cleanroom filter air outlet assembly introduces air through a side air inlet pipe, filters it through a filter element, and then exhausts it through the ventilation on the top cover, thus achieving air filtration and purification. The positioning frame is fixed by the cooperation of two positioning plates and corresponding positioning grooves, thereby fixing the filter element. The positioning plate is locked by the abutment of the rotating plate and the groove, thereby improving the fixing effect of the positioning frame and preventing vibration from causing it to fall off.

[0014] In this utility model, a replaceable modular cleanroom filter air outlet assembly is described. By controlling two handles to drive two rotating plates to rotate half a turn, the rotating plates are dislodged from the grooves. Then, pulling the two handles drives the two connecting shafts to move away from each other, and through the corresponding connecting discs, drives the two positioning plates to move away from each other, so that the positioning plates are dislodged from the positioning slots, releasing the fixation of the positioning frame. Then, the positioning frame and the top cover can be disassembled, and the filter element can be taken out upwards for easy cleaning or replacement.

[0015] This utility model has a reasonable structural design. The positioning mechanism facilitates the quick installation and removal of the filter element in the cleanroom air vent assembly. It adopts a dual-action positioning mechanism of rotation unlocking and translation separation, which can complete the filter element replacement without tools, significantly shortening downtime. The rigid contact between the rotating plate and the groove and the spring reset double locking prevent the filter element from shifting due to airflow impact or equipment vibration.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Referring to Figures 1-6, a replaceable modular cleanroom filter air outlet assembly includes: an outer shell 1, a top cover 2, and a filter element 4. A support plate 301 is fixedly installed inside the outer shell 1. A fixing frame 3 is fixedly installed on the top of the support plate 301. A positioning frame 201 is fixedly installed on the bottom of the top cover 2. The positioning frame 201 and the filter element 4 are both set inside the fixing frame 3. Positioning mechanisms 5 are provided on both sides of the fixing frame 3. The positioning mechanism 5 includes: a positioning seat 501 and a rotating plate 506. A connecting shaft 503 is fixedly installed inside the rotating plate 506. A connecting disc 502 is fixedly installed at one end of the connecting shaft 503. The connecting disc 502 is rotatably installed on one side of the positioning seat 501. Two fixing plates 6 are fixedly installed on the inner walls of both sides of the outer shell 1. The two fixing plates 6 on the same side have grooves 601 on the side that are close to each other. The rotating plate 506 movably abuts against the side wall of the corresponding groove 601. Positioning slots are provided on both sides of the positioning frame 201. The positioning plate is movably engaged in the corresponding positioning slot.

[0025] In this embodiment, the positioning seat 501 is slidably sleeved on the outside of the corresponding fixed plate 6. A limit ring and a torsion spring 507 are fixedly installed on one side of the positioning seat 501. The limit ring is movably abutted against the outside of the connecting plate 502. The other end of the torsion spring 507 is fixedly connected to the corresponding rotating plate 506.

[0026] In this embodiment, a connecting spring 508 is fixedly installed on the other side of the rotating plate 506, and the other end of the connecting spring 508 is fixedly installed on the side wall of the outer shell 1, thereby positioning the rotating plate 506. Circular holes are opened on both sides of the outer shell 1, and the other end of the connecting shaft 503 passes through the circular hole and is fixedly installed with a pull plate 504. A handle 505 is fixedly installed inside the pull plate 504.

[0027] In this embodiment, a through hole is provided at the top of the top plate, and a side air inlet pipe 101 is connected to the front side of the top plate.
