Description
Technical Field
[0001] This utility model belongs to the field of air purification devices, specifically referring to an FFU fan filter unit. Background Technology
[0002] An FFU (Fan Filter Unit) is a modular air purification device widely used in laboratories, cleanrooms, medical operating rooms, and other places with high air quality requirements. Its main function is to draw in air via a fan, filter it through the filter components, and then output clean air, while also preventing harmful gases or dust from escaping.
[0003] In existing technologies, filter replacement of FFU (Fan Filter Unit) filters typically relies on manual operation. When the filter reaches its preset service life or its filtration efficiency declines, operators need to stop the machine, open the equipment casing, manually remove the old filter, and replace it with a new one. This replacement method has several drawbacks: firstly, the manual replacement process is cumbersome and consumes significant manpower and time, especially in large cleanrooms where there are many FFU units, making batch replacements a labor-intensive task.

The propulsion assembly is located at the connection between the mounting frame and the storage box. A propulsion groove is provided at the connection between the storage box and the mounting frame. The propulsion assembly includes a propulsion plate, and the propulsion plate and the propulsion groove are slidably connected.
[0006] Furthermore, a drop groove is provided at the lower part of the mounting frame, and the drop groove and the bottom stop groove are connected in a through manner.
[0007] Furthermore, a hook is fixedly provided at the lower part of the mounting frame near the drop groove for movably hanging plastic bags.
[0008] Furthermore, the discharge assembly also includes a first electric telescopic rod, which is located on the side of the storage box. The fixed end of the first electric telescopic rod is fixedly connected to the storage box, and the movable end of the first electric telescopic rod is fixedly connected to one side of the bottom baffle to control the movement of the bottom baffle.
[0009] Furthermore, the storage mechanism also includes a second electric telescopic rod, the fixed end of which is fixed to the outside of the storage box, the movable end of which slides through the storage box, and a fixed plate is fixed to the movable end, the fixed plate and the filter plate being movably abutted together.
[0010] Furthermore, the bottom of the inner side of the storage box is designed with an arc shape, and a sealing door is hinged to the upper part of the storage box. The filter plate is slidably connected to the inner side of the storage box for holding the filter plate.
[0011] Furthermore, the propulsion assembly also includes a third electric telescopic rod, the fixed end of which is fixed to the side of the storage box, and the movable end of which slides through the storage box, and the movable end is fixedly connected to the propulsion plate.

The discharge assembly 3 is located at the lower part of the mounting frame 1 and includes a bottom baffle 302. A bottom baffle groove 303 is provided on the lower front side of the mounting frame 1. The bottom baffle 302 and the bottom baffle groove 303 are slidably connected. The lower part of the mounting frame 1 has a... There is a drop trough 304, which is connected to the bottom baffle 303. The lower part of the mounting frame 1 is fixed with a hook 305 near the drop trough 304 for movably hanging plastic bags. The discharge assembly 3 also includes a first electric telescopic rod 301, which is located on the side of the storage box 401. The fixed end of the first electric telescopic rod 301 is fixed to the storage box 401, and the movable end of the first electric telescopic rod 301 is fixed to one side of the bottom baffle 302 to control the movement of the bottom baffle 302.
[0021] like Figure 1-2As shown, the storage mechanism 4 is located on the side of the mounting frame 1. The storage mechanism 4 includes a storage box 401, which is fixedly connected to the side of the mounting frame 1. The filter plate 6 is movably disposed inside the storage box 401. The storage mechanism 4 also includes a second electric telescopic rod 403. The fixed end of the second electric telescopic rod 403 is fixed to the outside of the storage box 401, and the movable end of the second electric telescopic rod 403 slides through the storage box 401. A fixing plate 404 is fixedly provided at the end of the movable end, and the fixing plate 404 and the filter plate 6 are movably abutted together. The bottom of the inner side of the storage box 401 is designed with an arc-shaped structure. A sealing door 402 is hinged to the upper part of the storage box 401. The filter plate 6 is slidably connected to the inner side of the storage box 401 for holding the filter plate 6.
[0022] like Figure 1-4 As shown, the propulsion assembly 5 is located at the connection between the mounting frame 1 and the storage box 401. A propulsion groove 503 is provided at the connection between the storage box 401 and the mounting frame 1. The propulsion assembly 5 includes a propulsion plate 502, which is slidably connected to the propulsion groove 503. The propulsion assembly 5 also includes a third electric telescopic rod 501. The fixed end of the third electric telescopic rod 501 is fixed to the side of the storage box 401, and the movable end of the third electric telescopic rod 501 slides through the storage box 401. The movable end is fixedly connected to the propulsion plate 502.
