[0002] With the market demand, FFU plays a key role in cleanrooms. It provides a clean air environment and reduces the deposition of particulate matter and pollutants through functions such as air filtration, air circulation and pressure difference control. At the same time, it can also control the noise level and help maintain a quiet working environment. Some advanced FFUs can also achieve precise control of temperature and humidity. By using FFU, the cleanliness and comfort of the cleanroom can be effectively improved to meet the requirements for a clean environment.

[0003] There are thousands of FFUs in a factory. After a period of use, the filter cotton on some FFUs cannot guarantee cleanliness and needs to be replaced. If the filter cotton on each FFU is replaced manually, it will take a lot of time and be inefficient. Summary of the invention

The same material can ensure the consistency of the filtering effect. The motor is used to automatically pull the filter cotton to replace, which reduces the danger of the staff during the replacement process. The spare filter layer is automatically pulled out for replacement, which can always maintain the filtering effect at the air inlet. The design of the storage box, the first plate body and the second plate body makes the storage and traction of the spare filter layer more stable, ensures a smooth transition at the connection between the filter layer and the spare filter layer, and improves the operating stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is an overall structural diagram of an air intake device proposed by the present invention. DETAILED DESCRIPTION

[0016] refer to Figure 1The present invention proposes an air inlet device, which has a filter layer 1 at the air inlet for filtering the gas flowing into the air inlet from the air inlet, and can efficiently filter the gas flowing into the air inlet from the air inlet, effectively remove particulate matter and pollutants in the air, and provide a clean air environment for the dust-free workshop. The air inlet device also includes a first storage roller 2, a spare filter layer 3, a connecting layer 4, and a second storage roller 5. The first storage roller 2 and the second storage roller 5 are both firmly mounted on the air inlet device to ensure stability and reliability during operation. The spare filter layer 3, the filter layer 1, and the connecting layer 4 are adapted and connected in sequence, which not only fits tightly in structure, but also all three are filter cottons, ensuring the consistency and stability of the filtering effect. The spare filter layer 3, the filter layer 1, and the connecting layer 4 are adapted and connected in sequence and formed in one piece. This design makes the filtration system more compact and reduces the possibility of air leakage. The spare filter layer 3 movably wound on the first storage roller 2 and the connecting layer 4 movably wound on the second storage roller 5 respectively straighten the filter layer 1 from both sides of the filter layer 1 and press it against the air inlet wall, ensuring that the filter layer can fully play its role and effectively intercept impurities in the air.

[0017] The connecting layer 4 specifically includes a connecting section with one end pre-wound and fixed on the first receiving roller 2 and a partially used filter layer 1. Such a design enables that during the filtering process, as the used filter layer is continuously rolled into the second receiving roller 5, a new spare filter layer can be added to the filtering position in time, thereby achieving the continuity of the filtering process.

[0018] In order to realize the function of automatically replacing the filter layer, the air inlet device is also equipped with a motor 6. The motor 6 is tightly connected to the second storage roller 5, and can drive the second storage roller 5 to rotate stably. At the same time, the air inlet device is also provided with an air pressure sensor and a controller. The air pressure sensor is installed in the air duct of the air inlet device, and can accurately monitor the real-time wind pressure in the air duct when the air inlet device is working, and transmit the real-time wind pressure data to the controller. The controller makes a judgment based on the preset wind pressure value. When the real-time wind pressure is lower than the preset wind pressure, it indicates that the filter layer may be blocked or the filtering effect is reduced. At this time, the controller will control the motor 6 to drive the second storage roller 5 to rotate. As the second storage roller 5 rotates, the connection layer 4 continues to be wound on the second storage roller 5, and the used filter layer 1 is pulled to become a part of the connection layer 4. At the same time, part of the spare filter layer 3 is pulled out to become the filter layer 1 that is straightened and pressed against the air inlet wall, thereby realizing the function of automatically replacing the filter layer and ensuring that the air inlet device always maintains a good filtering effect.

[0019] In order to better store the spare filter layer 3, the air inlet device further includes a storage box 7. The storage box 7 has an opening, and the first storage roller 2 and part of the spare filter layer 3 are stored in the storage box 7, which not only saves space but also protects the spare filter layer from the influence of the external environment. One end leading out from the opening is closely connected with the filter layer 1, ensuring a quick response when the filter layer needs to be replaced.

[0020] In addition, the air inlet device also includes a first plate body 8 and a second plate body 9 which are fixedly connected to the air inlet device and arranged in parallel and spaced apart. The remaining part of the spare filter layer 3 between the filter layer 1 and the spare filter layer 3 in the storage box 7 is movably clamped between the first plate body 8 and the second plate body 9. This clamping design allows the spare filter layer to remain stable during operation without misalignment or loosening, and at the same time ensures that the wound spare filter layer 3 will not be pulled out all at once after the motor 6 is started. The spare filter layer 3 is in contact with the inner walls of the first plate body 8 and the second plate body 9 relative to each other, ensuring the flatness and sealing of the filter layer. The first plate body 8 and the second plate body 9 are both the same width as the spare filter layer 3, making the clamping more uniform and further improving the filtering effect. Moreover, the lower surface of the first plate body 8 is arranged coplanar with the air inlet wall, ensuring the close fit between the filter layer and the air inlet to prevent air leakage. The first plate body 8 and the second plate body 9 are both fixed at the opening of the storage box 7, making the entire structure more stable. The connection between the filter layer 1 and the part of the spare filter layer 3 in the storage box 7 and the remaining part of the spare filter layer 3 and the part of the spare filter layer 3 located in the storage box 7 has a smooth transition, ensuring that the spare filter layer 3 can move stably.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
