The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments.

[0021] Embodiment 1:

[0022] Please refer to Figures 1 - 3 As shown in the figure, the present invention provides a filtering device for a laminar flow ceiling air supply, including a static pressure box 1. A partition 2 is fixedly connected to the top of the inner cavity of the static pressure box 1. Both sides of the static pressure box 1 are penetrated and connected with mounting cylinders 3. One end of the mounting cylinder 3 is fixedly connected with a clamping frame 4. A filter 5 is movably connected to the inner cavity of the clamping frame 4. An opening 6 is formed at the bottom of the static pressure box 1. Fixing shells 7 are fixedly connected to both sides of the top of the inner cavity of the static pressure box 1. A movable block 8 is movably connected to the inner cavity of the fixing shell 7. A top rod 9 is fixedly connected to the bottom of the movable block 8. A spring 10 is sleeved on the surface of the top rod 9. A pressing rod 11 is fixedly connected to the top of the movable block 8. A surgical lamp mounting port 12 is fixedly connected to the bottom of the partition 2. Air inlets 13 are arranged on the front and back of the static pressure box 1. The filter 5 is inserted into the inner cavity of the static pressure box 1. After the threaded hole on one side of the filter 5 is aligned with the through hole at one end of the mounting cylinder 3, a long screw is inserted into the inner cavity of the mounting cylinder 3, and the long screw is screwed until one end of it is screwed into the threaded hole on one side of the filter 5.

[0023] The application of the mounting cylinder 3, the clamping frame 4, the limiting frame, the fixing shell 7, the movable block 8, the top rod 9, the spring 10 and the pressing rod 11 in this technical solution realizes the purpose of quickly disassembling and assembling the laminar flow ceiling air supply filtering device, providing great convenience for the later maintenance work.

[0024] Embodiment 2:

[0025] On the basis of Embodiment 1, as shown in the figure of the present invention Figures 1 - 2 As shown, a isolation cover 14 is arranged at the bottom of the static pressure box 1 and inside the opening 6. Mesh holes are formed on the surface of the isolation cover 14. Mounting frames 15 are fixedly connected to the tops of both sides of the static pressure box 1. Mounting holes are formed on the surface of the mounting frames 15. A connecting plate is fixedly connected to the top of the static pressure box 1. A fixing frame 16 is fixedly connected to the top of the connecting plate.

[0026] Adopting the above technical solution is mainly to protect the bottom of the filter 5, strengthen the fixing effect of the static pressure box 1 and fix the filter 5 on the driving mechanism. The isolation cover 14 itself has a filtering function, which can further improve the filtering effect, reduce the filtering pressure of the filter 5, pass the mounting bolts through the mounting holes and continue to screw them into the accessory parts of the driving mechanism, strengthen the connection stability between the static pressure box 1 and the driving mechanism, and fix the fixing frame 16 to the output end of the driving mechanism through fixing screws, which is convenient for the driving mechanism to drive the static pressure box 1 to move.

[0027] Embodiment Three:

[0028] Based on Embodiment Two, as shown in the present utility model Figure 2 , both sides of the partition plate 2 are fixedly connected with limiting frames, magnet sheets are fixedly connected inside the cavities of the limiting frames, a fastening sleeve is fixedly connected to the top inside the opening 6, and the inner cavity of the fastening sleeve is movably connected to the surface of the filter 5.

[0029] Adopting the above technical solution is mainly to achieve the purpose of improving the installation stability of the filter 5 and wrapping and fixing the bottom of the filter 5. When the filter 5 is inserted into the static pressure box 1, the iron sheet on one side of the filter 5 is attracted by the magnet sheet inside the cavity of the limiting frame, which can limit and fix the filter 5. When the filter 5 is inserted into the opening 6, it will first pass through the inner cavity of the fastening sleeve, and the fastening sleeve wraps around the surface of the filter 5, which can improve the installation stability of the filter 5.

[0030] The working principle of the present utility model is as follows: First, insert the filter 5 into the inner cavity of the static pressure box 1. After the threaded hole on one side of the filter 5 is aligned with the through hole at one end of the mounting cylinder 3, insert a long screw into the inner cavity of the mounting cylinder 3 and turn the long screw until one end of it is screwed into the threaded hole on one side of the filter 5. After the installation of the filter 5 is completed, then install and fix the fixing frame 16 on the output end of the driving mechanism on the ceiling through fixing screws. During the use of the laminar flow air supply ceiling device, when it is necessary to disassemble, clean or replace the filter 5, just operate the above installation steps in reverse.
