Description

Technical Field

[0001] This utility model relates to the technical field of fan filtration equipment, and in particular to an automatic cleaning device for FFU fan filters. Background Technology

[0002] In many industrial and commercial environments, such as electronics manufacturing workshops, laboratories, and hospital operating rooms, there are strict requirements for air quality. FFU (Fan Filter Unit) is widely used in these places to filter dust, impurities, and other particles from the air to provide a clean air environment.

[0003] The fan filter, as one of the core components of the FFU (Fan Filter Unit), plays a crucial filtering role. However, with increased usage time, dust and impurities gradually accumulate on the fan filter, leading to a decrease in filtration efficiency, reduced airflow, and consequently affecting the performance of the entire air purification system.

[0004] Traditional methods for cleaning fan filters mostly involve manual cleaning, which has several drawbacks. First, manual cleaning requires a significant amount of manpower and time, especially in large air purification systems where a large number of filters need to be cleaned. Manual cleaning is inefficient and can easily damage the filters, such as through over-washing or improper wiping, thus shortening their lifespan. To address these issues, an automatic FFU (Fan Filter Unit) filter cleaning device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic cleaning device for FFU fan filters, which aims to improve the problem that some FFU fan filters are inconvenient to clean automatically in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic cleaning device for FFU (Fan Filter Unit) filters includes a housing, a cleaning mechanism fixedly connected to the inner wall of the housing, and a collection mechanism installed at the bottom of the housing. The cleaning mechanism includes two electric guide rails, with their far sides fixedly connected to the inner walls of the front and rear sides of the housing. A slider is slidably connected to the outer wall of each electric guide rail. A connecting plate is fixedly connected to the near side of each slider. A long box is fixedly connected to the near side of each connecting plate. A motor is fixedly connected to the top of the front connecting plate.

A cross structure is fixedly connected to the bottom of each rotating column, and multiple brushes are fixedly connected to the bottom of the cross structure. As a further description of the above technical solution: The collection mechanism includes two electric guide rails, with their adjacent sides fixedly connected to the front and rear sides of the bottom of the box. A slider is slidably connected to the outer wall of the electric guide rail, and an L-shaped plate is fixedly connected to the bottom end of the slider. A collection box is fixedly connected to the adjacent side of the two L-shaped plates. A dust filter plate is fixedly connected to the inner wall of the collection box. Multiple support blocks are fixedly connected to the bottom inner wall of the collection box. A motor is fixedly connected to the adjacent side of the two support blocks, and a fan blade is fixedly connected to the drive end of the motor. As a further description of the above technical solution: An air filter is fixedly connected to the inner wall of the box, and the bottom side of the multiple brushes is in contact with the top side of the air filter. As a further description of the above technical solution: A fan is fixedly connected to the top of the box, and the outer wall of the rotating rod is rotatably connected to the inner wall of the long box; As a further description of the above technical solution: The outer walls of the two sliders are in contact with the inner wall of the box, and the outer wall of the long box is in contact with the inner wall of the box.

[0007] This utility model has the following beneficial effects: 1. In this utility model, a motor drives a rotating rod to rotate, and a bevel gear on the rotating rod meshes with a bevel gear to transmit power to the rotating column, thereby driving the cross structure and brush to rotate. At the same time, an electric guide rail and a slider work together to move the connecting plate and the long box left and right, which can thoroughly clean the surface of the air filter, thus ensuring the cleaning effect of the air filter and making the air passing through the air filter cleaner, meeting the usage requirements.

[0008] 2. In this utility model, the second motor drives the fan blades to rotate, generating negative pressure in the collection box.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an automatic cleaning device for FFU (Fan Filter Unit) fans and filters, comprising a housing 1. A fan 3 is fixedly connected to the top of the housing 1. The main function of the fan 3 is to promote airflow and provide aerodynamic power for the entire system. The operation of the fan 3 drives airflow within the device, allowing the air to pass through components such as the air filter 2, and is one of the power sources for achieving air filtration and cleaning. A cleaning mechanism is fixedly connected to the inner wall of the housing 1, and a collection mechanism is installed at the bottom of the housing 1. The housing 1 is the outer shell of the entire automatic cleaning device for FFU fans and filters, serving to protect the internal structure, providing installation space for the fan 3, cleaning mechanism, and collection mechanism, integrating various components together, ensuring the integrity of the device, and preventing external factors from interfering with the internal structure.

[0013] The cleaning mechanism includes two electric guide rails 4, with their far sides fixedly connected to the inner walls of the front and rear sides of the housing 1. Slider blocks 5 are slidably connected to the outer walls of the electric guide rails 4. The outer walls of the two sliders 5 contact the inner walls of the housing 1. The electric guide rails 4 provide precise guidance and a moving track for the sliders 5. Through electric control, the sliders 5 slide on their outer walls. Connecting plates 6 are fixedly connected to the near sides of the two sliders 5. The function of the sliders 5 is to transmit the linear movement of the electric guide rails 4 to the connecting plates 6. Connecting plates 6 are fixedly connected to the near sides of the two connecting plates 6. A long box 8 is fixedly connected, and the outer wall of the long box 8 is in contact with the inner wall of the box body 1. When the slider 5 moves left and right, the connecting plate 6 transmits this motion to the long box 8, thereby driving the long box 8 and the cleaning components inside to move left and right. A motor 7 is fixedly connected to the top of the front connecting plate 6, and a rotating rod 9 is fixedly connected to the drive end of the motor 7. The outer wall of the rotating rod 9 is rotatably connected to the inner wall of the long box 8. The motor 7 is one of the power sources of the cleaning mechanism. When the motor 7 is turned on, it generates power and drives the rotating rod 9 to rotate, thereby starting the rotation mechanism of the entire cleaning component.

[0014] Multiple bevel gears 10 are fixedly connected to the outer wall of the rotating rod 9, and multiple rotating columns 11 are rotatably connected to the bottom inner wall of the long box 8. The long box 8 provides installation space and protection for the internal components such as the rotating rod 9, bevel gears 10, and rotating columns 11. A bevel gear 12 is fixedly connected to the top of the rotating column 11. The outer side of the bevel gear 12 is meshed with the outer side of the bevel gear 10. When the rotating rod 9 rotates, the bevel gear 10 rotates accordingly and then transmits power to the bevel gear 12. By meshing with the bevel gear 12, the bevel gear 10 changes the direction of power transmission, enabling the rotating column 11 to rotate. A cross structure 13 is fixedly connected to the bottom end of the rotating column 11. The rotational power of the rotating column 11 is transmitted to the cross structure 13, thereby driving the cross structure 13 to rotate. Multiple brushes 14 are fixedly connected to the bottom end of the cross structure 13. An air filter 2 is fixedly connected to the inner wall of the housing 1. The bottom sides of the multiple brushes 14 are in contact with the top side of the air filter 2. When air flows through the air filter 2 under the action of the fan 3, dust and impurities in the air are intercepted on the surface of the filter, ensuring that the filtered air is cleaner and meets the usage requirements. The cross structure 13 evenly transmits the rotational motion of the rotating column 11 to the multiple brushes 14, enabling the brushes 14 to rotate and clean the surface of the air filter 2 in a stable posture, ensuring effective cleaning of dust on the surface of the air filter 2.

[0015] Reference Figure 1 , Figure 4 and Figure 5The collection mechanism includes two electric guide rails 16, with their adjacent sides fixedly connected to the front and rear sides of the bottom of the housing 1. A slider 17 is slidably connected to the outer wall of each electric guide rail 16. Limiting blocks 18 are fixedly connected to the left and right sides of each electric guide rail 16. The left and right sides of the slider 17 contact the adjacent sides of the two limiting blocks 18. The main function of the limiting blocks 18 is to limit the movement range of the slider 17, preventing it from sliding excessively on the electric guide rails 16, thus ensuring the normal operation of the collection mechanism and preventing component damage. An L-shaped plate 19 is fixedly connected to the bottom of the slider 17, and a collection box 20 is fixedly connected to the adjacent sides of the two L-shaped plates 19. The electric guide rails 16 provide guidance and a track for the slider 17's movement. Through electric control, the slider 17 can slide smoothly on its outer wall and move synchronously with the cleaning mechanism, ensuring that the collection box 20 can accurately collect dust and impurities. The L-shaped plate 19 connects the slider 17 and the collection box 20, transmitting the movement of the slider 17 to the collection box 20. An air vent 15 is fixedly connected to the bottom inner wall of the box 1. The top side of the collection box 20 contacts the bottom side of the air vent 15. The air vent 15 separates the box 1 and the collection box 20 while allowing air to pass through. Some of the dust and impurities cleaned by the cleaning mechanism fall onto the air vent 15 and are then sucked onto the dust filter plate 21 under negative pressure. A dust filter plate 21 is fixedly connected to the inner wall of the collection box 20. Multiple support blocks 22 are fixedly connected to the bottom inner wall of the collection box 20. A second motor 23 is fixedly connected to the adjacent side of two support blocks 22. The support blocks 22 support the second motor 23, ensuring its stable installation within the collection box 20. A fan blade 24 is fixedly connected to the drive end of the second motor 23. Under the negative pressure generated by the fan blade 24, dust and impurities are drawn onto the dust filter plate 21. The collection box 20 collects these dust and impurities, preventing them from falling into the working environment and maintaining a clean environment. Ventilation ducts are provided on both the front and rear sides of the bottom of the collection box 20. The outer wall of the fan blade 24 contacts the inner wall of the ventilation duct. The main function of the ventilation duct is to provide a channel for airflow. When the second motor 23 drives the fan blade 24 to rotate, generating negative pressure within the collection box 20, external air enters the collection box 20 through the ventilation duct, allowing the air inside the box to circulate and ensuring the formation of a negative pressure environment.

[0016] Working principle: By turning on the motor 7, the power is generated to drive the rotating rod 9 to rotate, which in turn drives the bevel gear 10 on it to rotate. Since the bevel gear 12 and the bevel gear 10 are meshed, the rotation of the bevel gear 10 drives the bevel gear 12 to rotate. The rotation of the bevel gear 12 drives the rotating column 11 to rotate, which in turn drives the cross structure 13 to rotate. The rotation of the cross structure 13 drives the brush 14 to rotate and clean the surface of the air filter 2. At the same time, the electric guide rail 4 and the slider 5 drive the connecting plate 6 to move left and right. The movement of the connecting plate 6 drives the long box 8 to move left and right, thereby achieving a comprehensive cleaning of the air filter 2. By turning on the motor 23, the power is generated to drive the fan blade 24 to rotate. The rotating fan blade 24 generates negative pressure in the collection box 20. Some of the dust and impurities cleaned by the cleaning mechanism will fall onto the air outlet 15. The negative pressure will suck the dust and impurities on the air outlet 15 onto the dust filter plate 21. At the same time, the electric guide rail 26 and the slider 27 move synchronously with the cleaning mechanism to prevent the falling dust and impurities from falling into the working environment.
