[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Reference Figure 1-4 An anti-static interference FFU includes a shell 1, the inner wall of the shell 1 is fixedly connected to a support plate 2, the upper surface of the shell 1 is fixedly connected to two handles 11, the outer surface of each handle 11 is covered with an anti-slip cover 12, and the cooperation between the handle 11 and the anti-slip cover 12 makes it easier for the staff to lift the fan assembly.
[0025] The inner wall of the support plate 2 is fixedly connected to a rotating motor 3, and a rotating base 4 is provided above the rotating motor 3. The front and back sides of the outer shell 1 are fixedly connected to two mounting plates 13, and the upper surface of each mounting plate 13 is provided with a mounting hole 14. The mounting plates 13 and the mounting holes 14 are matched, and the overall fan assembly can be fastened using external threaded rods and threaded caps.
[0026] Six fan blades 7 are fixedly connected to the upper surface of the rotating base 4, a sealing cover 5 is fixedly connected to the inner wall of the rotating base 4, and two limit bars 15 are fixedly connected to the upper surface of the outer shell 1. The inner walls of the two limit bars 15 are slidably connected to the front filter plate 16. The cooperation between the limit bar 15 and the front filter plate 16 optimizes the air entering the fan assembly. Replacing the front filter plate 16 once in a while can increase the service life of the fan assembly.
[0027] The upper surface of the sealing cover 5 is fixedly connected to the mounting tube 6, the upper surfaces of the six fan blades 7 are commonly fixedly connected to the rotating top cover 8, the left side of the outer shell 1 is fixedly connected to the power socket 17, the left side of the outer shell 1 is fixedly connected to the rotating knob 18, the power socket 17 is electrically connected to the rotating motor 3, so as to provide electrical energy to the rotating motor 3, and the power control speed of the rotating motor 3 can be adjusted by rotating the knob 18.
[0028] The outer surface of the rotating top cover 8 is fixedly connected with anti-static paint 9, and the outer surface of the anti-static paint 9 is in contact with the inner wall of the shell 1. A support frame 19 is provided inside the shell 1, and the inner wall of the support frame 19 is fixedly connected with a HEPA filter 20. The support frame 19 and the HEPA filter 20 cooperate to filter the air at the air outlet, thereby providing high-quality air and wind force for its special equipment.
[0029] The outer surface of the output end of the rotating motor 3 contacts the inner wall of the mounting tube 6, and a bolt 10 is provided on the outside of the mounting tube 6. Four limit blocks 21 are provided above the support frame 19. The bottom surface of each limit block 21 contacts the upper surface of the support frame 19, and the outer surface of each limit block 21 is fixedly connected to the inner wall of the outer shell 1. The limit block 21 can limit the support frame 19 to prevent the support frame 19 from tilting during installation and affecting the quality of filtered air.
[0030] One end of the bolt 10 close to the mounting tube 6 passes through the mounting tube 6 and is threadedly connected to the inner wall of the output end of the rotating motor 3. The inner wall of the rotating top cover 8 is fixedly connected to a support net 22. The support net 22 is located above the outer shell 1. The support net 22 has the effect of protecting the safety of the staff and also has a certain supporting force.
[0031] The working principle of the present invention is as follows: when in use, first, an external wire is electrically connected to the power socket 17, and the power socket 17 is electrically connected to the rotating motor 3 to provide electric energy for the rotating motor 3. At this time, the rotating motor 3 and the mounting tube 6 are connected together by the bolt 10. The power provided by the rotating motor 3 can drive the mounting tube 6 to rotate. The mounting tube 6 is fixedly connected to the sealing cover 5 to ensure that the mounting tube 6 can drive the sealing cover 5 to rotate. At this time, the sealing cover 5, the rotating base 4, the fan blades 7 and the rotating top cover 8 are fixedly connected to each other. When the sealing cover 5 rotates, the wind wheel assembly can be driven to rotate as a whole.
[0032] At this time, the suction force generated by the rotation of the wind wheel assembly can draw in external air. First, the air is filtered through the front filter plate 16, and then the air passes between the rotating base 4 and the rotating top cover 8. At this time, the outer surfaces of the rotating base 4, the fan blades 7 and the rotating top cover 8 are all coated with anti-static paint 9, which makes it difficult to generate static electricity during the rotation, thereby protecting the rotating wind wheel and extending the service life of the rotating wind wheel. Finally, the wind wheel assembly is used to blow the air out of the outer casing 1. At the same time as blowing it out of the outer casing 1, the HEPA filter 20 is further filtered to ensure that the quality of the output air is relatively clean.
