Description

Technical Field

[0001] This utility model relates to the field of FFU air purification technology, and in particular to an FFU air purification unit. Background Technology

[0002] FFU (Follicular Unit Extraction) is a device used to provide a highly clean environment, commonly used in semiconductor manufacturing, biopharmaceuticals, hospitals, and food processing, where strict cleanliness is required.

[0003] For example, an FFU air purification unit with authorization announcement number "CN216384401U" uses the vibration of an exhaust fan to continuously compress a spring. The spring generates elasticity during compression, which reduces vibration and prevents it from being transmitted to the FFU body, thus avoiding damage. However, this device is inconvenient to adjust the air outlet angle, resulting in poor airflow performance. Furthermore, the rotating brush used to clean the filter can leave hard-to-reach areas, further hindering effective filter cleaning. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing an FFU air purification unit that can adjust the air outlet angle and improve the cleaning effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This FFU air purification unit includes a shell and an FFU body. The FFU body is installed on the inner wall of the shell. An adjustment device is provided at the right end of the shell. A filter structure is provided inside the shell. The left end of the shell is threadedly connected to the mesh plate by two first bolts. A straight plate is fixedly connected to the inner wall of the shell. The right end of the straight plate is threadedly connected to the outer wall of the motor by multiple screws.

[0006] Further improvements include a filter structure comprising a through hole and a frame. The outer wall of the frame is inserted into a groove on the inner wall of the outer shell. The inner wall of the frame is fixedly connected to the filter screen. The upper end of the frame penetrates the outer shell. The surface of the frame is provided with a through hole.

[0007] Further improvements include a motor output shaft that is rotatably connected to a straight plate via a bearing, and a motor output shaft that is fixedly connected to a fan.

[0008] Further improvements include a fixed connection between the air outlet of the FFU body and the bellows, a movable connection between the upper end of the outer shell and the protruding part of the cover via a bearing, and a handle fixedly connected to the outer wall of the cover.

[0009] Further improvements include an air outlet pipe and a rotating shaft. One end of each rotating shaft on both sides is movably connected to the outer casing via a bearing, and the other end of each rotating shaft on both sides is fixedly connected to the outer wall of the air outlet pipe. The lower end of the air outlet pipe is fitted with a second bolt, the outer wall of the second bolt is threadedly connected to a horizontal plate, and one end of the horizontal plate is fixedly connected to the outer casing.

[0010] Further improvements include: the outer wall of the air outlet duct is fitted to the dust cover; the dust cover is fixedly connected to the inner wall of the outer shell; and one end of the air outlet duct is fixedly connected to the corrugated pipe.

[0011] The beneficial effects of this utility model are as follows: With the cooperation of the filter structure and adjustment device, when not in use, the operator can pull the frame through the through-hole, causing the frame to move the filter screen out of the outer casing for cleaning. Simultaneously, the operator can rotate the first bolts on both sides to remove the screen for cleaning, open the cover, and inspect and clean the FFU body. The operator can also rotate the second bolt, causing the upper end of the second bolt to push the air outlet pipe to rotate around the pivot, changing the orientation of the right end of the air outlet pipe and thus adjusting the air outlet angle.

[0012] By installing a rubber damper at the pivot point, the angle of the air outlet duct can be fixed. The internal filter screen can be disassembled and cleaned, resulting in better cleaning performance. At the same time, the airflow direction can be adjusted to improve the airflow efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6 In this embodiment, an FFU air purification unit includes a housing 1 and an FFU body 10. The FFU body 10 is installed on the inner wall of the housing 1. The FFU is a modular terminal air supply device with self-powered power and high-efficiency filtration function. An adjustment device 9 is provided on the right end of the housing 1. A filter structure 2 is provided inside the housing 1. The left end of the housing 1 is threadedly connected to the mesh plate 5 by two first bolts 6. The mesh plate 5 is made of stainless steel plate with multiple through holes. A straight plate 4 is fixedly connected to the inner wall of the housing 1. The right end of the straight plate 4 is threadedly connected to the outer wall of the motor 3 by multiple screws.

[0022] The output shaft of motor 3 is rotatably connected to straight plate 4 through bearing. Motor 3 can meet the working requirements according to actual needs. The output shaft of motor 3 is fixedly connected to fan 7. Motor 3 and fan 7 form a negative pressure fan. The air outlet of FFU body 10 is fixedly connected to bellows 12. The upper end of outer shell 1 is movably connected to the protruding part of cover 8 through bearing. A handle is fixedly connected to the outer wall of cover 8. The outer wall of air outlet pipe 901 is close to dust cover 11. Dust cover 11 is fixedly connected to the inner wall of outer shell 1. One end of air outlet pipe 901 is fixedly connected to bellows 12.

[0023] The filter structure 2 includes a through hole 202 and a frame 203. The outer wall of the frame 203 is inserted into a groove on the inner wall of the outer shell 1. The inner wall of the frame 203 is fixedly connected to the filter screen 201. The upper end of the frame 203 penetrates the outer shell 1. The surface of the frame 203 is provided with a through hole 202.

[0024] The adjusting device 9 includes an air outlet pipe 901 and a rotating shaft 902. One end of each rotating shaft 902 is movably connected to the outer casing 1 via a bearing, and the other end of each rotating shaft 902 is fixedly connected to the outer wall of the air outlet pipe 901. The lower end of the air outlet pipe 901 is in contact with the second bolt 904. The outer wall of the second bolt 904 is threadedly connected to the horizontal plate 903. One end of the horizontal plate 903 is fixedly connected to the outer casing 1.

[0025] Working principle:

[0026] When using an FFU for air purification:

[0027] The control motor 3 is activated, causing its output shaft to rotate and drive the fan 7 to rotate. The fan 7 draws outside air into the housing 1 through the mesh plate 5. After the air passes through the filter screen 201 (which can be made of non-woven fabric) to filter dust, it enters the FFU body 10. When the fan inside the FFU body 10 is activated, it generates negative pressure and draws in surrounding air (including pollutants) from the top or side, intercepting particles ≥5μm (such as construction residues) and protecting the HEPA / ULPA filter that filters out particles 0.3~0.12μm (including bacteria and viruses), ensuring that the air cleanliness meets the standards. The filtered air is delivered evenly in the form of laminar or turbulent flow, with a wind speed of 0.45m / s±20%. The delivered air is transported to the air outlet duct 901 through the corrugated pipe 12 and blown out.

[0028] Cleaning process:

[0029] When not in use, the operator can pull the frame 203 through the through hole 202, causing the frame 203 to move the filter screen 201 out of the outer shell 1. The operator can then clean the filter screen 201. At the same time, the operator can rotate the first bolts 6 on both sides to remove the screen plate 5, clean the screen plate 5, open the cover 8, and inspect and clean the FFU body 10.

[0030] Adjustment process:

[0031] The operator rotates the second bolt 904, causing the upper end of the second bolt 904 to push the air outlet pipe 901 to rotate around the pivot 902, thus changing the orientation of the right end of the air outlet pipe 901 and allowing it to rotate within a certain range to adjust the air outlet angle. By installing a rubber damper at the pivot 902, the angle of the air outlet pipe 901 can be fixed. When this device is used indoors, it is less affected by external factors, and the angle can be fixed by the rubber damper. When the external environment is harsh and there is a lot of vibration, horizontal plates 903 and second bolts 904 can be installed on both the upper and lower sides of the air outlet pipe 901. By clamping and limiting the movement on both sides, the angle of the air outlet pipe 901 can be kept fixed.

[0032] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
