Description

Technical Field

[0001] This utility model relates to the field of FUU purification unit technology, specifically a low-noise FFU purification unit. Background Technology

[0002] An FFU (Fan Filter Unit) is a high-efficiency air purification device, also known as a fan filter unit. It mainly consists of a fan, a high-efficiency filter, and a housing. The fan draws in indoor air, filters it through the high-efficiency filter, and then delivers the clean air out, thus purifying the indoor air. FFUs are designed with high-efficiency filtration, uniform airflow, low noise, and energy efficiency. They use high-efficiency filters to remove particulate matter, bacteria, viruses, and other pollutants from the air, improving indoor air cleanliness.

[0003] Most existing FUU air purification units do not have noise reduction structures. During the purification process, FUU air purification units mainly rely on the rotation of a fan to draw in air for purification. As the FUU air purification unit works, the fan rotation generates a lot of noise, which can cause discomfort to users.

[0004] To address this, we propose a low-noise FFU purification unit. Utility Model Content

Springs 7 are fixedly installed on the inner wall of the mounting base 4 on the side of the two slide plates 5 away from each other. A toothed rod 19 is fixedly installed on the top and bottom front ends of each slide plate 5. Multiple limiting parts 18 are fixedly installed on the front end of the fan base 2. Multiple gears 20 are rotatably sleeved on the outer side of the multiple limiting parts 18. The multiple gears 20 are respectively meshed and connected to the corresponding toothed rods 19. A locking rod 17 is fixedly installed on the side of the multiple gears 20 near the locking frame 16. The end of the multiple locking rods 17 away from the gears 20 is respectively locked in the corresponding locking frame 16. A motor 9 is fixedly installed at the rear end of the bracket 8. The output end of the motor 9 is fixedly installed on the connecting shaft 11.

[0021] An oil reservoir 21 is fixedly installed at the top of the fan base 2, and a guide pipe 26 is fixedly installed at the bottom of the oil reservoir 21. The bottom of the guide pipe 26 extends into the fan base 2 and is located at the top of the sponge sleeve 10. This design is beneficial to the use of this equipment. A guide seat 22 is fixedly installed at the bottom of the oil reservoir 21. The guide seat 22 is triangular. The inclined surface on the guide seat 22 facilitates the flow of lubricating oil to the guide pipe 26. An injection port 23 is fixedly installed at the top of the oil reservoir 21. A sealing plug 24 is threaded into the injection port 23. It is easy to add lubricating oil through the injection port 23. The connecting shaft 11 is rotatably connected to the sponge sleeve 10. The rear end of the sponge sleeve 10 is fixedly installed on the bracket 8. This design is beneficial to the use of this equipment. Pull plates 6 are fixedly installed at the front ends of the two slide plates 5. The pull plates 6 facilitate the sliding of the slide plates 5. The front ends of the purification unit body 1 are fixedly installed with handles 3 on the two mounting seats 4 on opposite sides. The handles 3 facilitate the lifting of this equipment.

[0022] Working principle: In use, the two sliding plates 6 are used to pull the two sliding plates 5 to move them away from each other. At this time, the two sliding plates 5 drive multiple toothed rods 19 to slide away from the side of the baffle 13. Since the toothed rods 19 are meshed with gears 20, the multiple gears 20 drive the locking rods 17 to deflect away from the side of the baffle 13. Then, the multiple positioning rods 15 at the rear end of the baffle 13 are inserted into the support ring 14. The pulling plates 6 are released. At this time, the spring 7 drives the sliding plates 5 to return to their original position, causing the multiple locking rods 17 to deflect and engage with the corresponding brackets 16. At the same time, the rear ends of the multiple locking rods 17 abut against the front end of the baffle 13, thus completing the installation of the baffle 13. Lubricating oil is added into the oil reservoir 21 through the injection port 23. Then, the sealing plug 24 is threaded onto the oil reservoir 21. Inside the injection port 23, the guide seat 22 guides the lubricating oil into the guide tube 26, and then drips it onto the sponge sleeve 10. The sponge sleeve 10 absorbs the lubricating oil, which lubricates the connecting shaft 11 and reduces the friction when the connecting shaft 11 rotates. The sound-insulating foam ring 25 absorbs the noise generated when the fan blade 12 rotates. This low-noise FFU purification unit is easy to use. The above components allow for quick disassembly and assembly between the baffle 13 and the fan base 2, which is beneficial for subsequent cleaning and replacement of the baffle 13. At the same time, the lubricating oil can lubricate the connecting shaft 11, reducing the friction when the connecting shaft 11 rotates. In conjunction with the sound-insulating foam ring 25, it absorbs the sound generated when the fan blade 12 rotates, thereby greatly reducing the noise generated when the equipment is working.
