Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 In this embodiment of the present invention, an air purification and air supply device for a laminar flow operating room includes an air supply duct 1 and an air supply box 2 installed at the inner cavity port of the air supply duct 1. It also includes an air supply fan blade 3 rotatably installed in the inner cavity of the air supply box 2 via a support frame. The shaft end of the air supply fan blade 3 is connected to a drive motor via a rotating shaft and a coupling. One end of the air supply box 2 is equipped with a filter screen 4 for intercepting dust, and the other end of the air supply box 2 is equipped with an activated carbon plate 6 fixed inside the frame 5 for filtering air.

[0027] It also includes a limiting mechanism 7 installed on the inner wall of the air supply box 2 to limit the connection between the air supply duct 1, the air supply box 2, and the air supply box 2 and the frame 5;

[0028] The limiting mechanism 7 includes a limiting unit and a transmission unit;

[0029] The transmission unit is used to provide power for the movement of the limit unit;

[0030] The limiting unit is used to limit the connection between the air supply box 2 and the air supply duct 1 and the frame 5;

[0031] The transmission unit includes a threaded rod 701, a transmission rod 702, and a rotating rod 703;

[0032] The threaded rod 701 is rotatably connected to the inner wall of the air supply box 2 by a thread and extends through the air supply box 2 to the outside of the air supply box 2. The threaded rod 701 is used to drive the rotating rod 703 to rotate through the transmission rod 702 fixed at the end. The rotating rod 703 is rotatably installed on the inner wall of the air supply box 2 and is axially slidably sleeved on the outer wall of the transmission rod 702. The rotating rod 703 is used to drive the first limiting block 704 and the second limiting block 706 fixed on the outer wall to rotate synchronously.

[0033] The limiting unit includes a first limiting block 704, a first guide groove 705, a second limiting block 706, a second limiting groove 707, and a second guide groove 708;

[0034] The first limiting block 704 is vertically fixed to the outer wall of the rotating rod 703, and the first limiting block 704 extends through the first guide groove 705 laterally opened on the air supply box 2 to the first limiting groove 8 on the inner wall of the air supply duct 1. The first limiting block 704 is used to provide a limit for the connection between the air supply box 2 and the air supply duct 1. The second limiting block 706 is horizontally fixed to the outer wall of the rotating rod 703, and the second limiting block 706 extends to the second limiting groove 707 laterally opened on the inner wall of the frame 5. The second limiting block 706 is used to provide a limit for the connection between the air supply box 2 and the frame 5.

[0035] The second guide groove 708 is axially formed on the inner wall of the frame 5 and extends to the outer wall of the frame 5 near the air supply box 2 in communication with the second limiting groove 707. The second guide groove 708 is used to provide an active path for the relative movement of the second limiting block 706.

[0036] In this embodiment: when maintenance or replacement of the activated carbon plate 6 and the fan blade 3 is required, manual force is applied to the threaded rod 701. The threaded rod 701 rotates along the threaded groove on the inner wall of the air supply box 2 and moves axially in the direction of the threaded groove. The threaded rod 701 drives the transmission rod 702 to move axially along the inner cavity of the rotating rod 703, and provides rotational thrust to the rotating rod 703 through the protrusion on the outer wall of the transmission rod 702. The rotating rod 703 rotates synchronously, causing the first limiting block 704 and the second limiting block 706 fixed on the outer wall to rotate. The first limiting block 704 enters the first guide groove 705 from the first limiting groove 8 opened on the inner wall of the air supply duct 1, while the second limiting block 706 rotates and moves from the vertical groove of the second limiting groove 707 to the axial movement groove of the second guide groove 708. At the end of the air supply duct 1 and the air supply box 2, the connection limit between them is released. The rotation of the rotating rod 703 synchronously drives the second limiting block 706, which is horizontally fixed on the outer wall, to rotate. The second limiting block 706 rotates 90 degrees and is still in the inner cavity of the second limiting groove 707. After the air supply box 2 is completely removed, the threaded rod 701 is rotated again to drive the rotating rod 703 and the second limiting block 706 to rotate again. The outer wall of the second limiting block 706 is aligned with the groove of the second guide groove 708, thereby releasing the connection limit between the activated carbon plate 6, the frame 5 and the air supply box 2. This facilitates the maintenance and replacement of the fan blades 3, the filter screen 4 and the activated carbon plates 6 distributed at the end of the air supply box 2, further improving work efficiency. It should be noted that a sealing strip is provided at the connection between the air supply duct 1 and the air supply box 2 to improve sealing.

[0037] Please refer to this carefully. Figures 1-4 The outer wall of the first limiting block 704 matches the inner side of the first guide groove 705. The first guide groove 705 is in the form of a quarter ring. The second limiting groove 707 is in the form of a semi-circular ring. The outer wall of the transmission rod 702 is formed with a protrusion extending into the inner cavity of the rotating rod 703. The inner cavity of the rotating rod 703 is formed with a sliding groove for relative movement of the outer wall of the transmission rod 702. There are two limiting mechanisms 7, which are symmetrically distributed on the inner wall of the air supply box 2.

[0038] In this embodiment: With this structure, while the threaded rod 701 rotates along the threaded groove on the inner wall of the air supply duct 1, the transmission rod 702 drives the rotating rod 703 to rotate. The transmission rod 702 moves axially along the inner cavity of the rotating rod 703, but does not drive the rotating rod 703 to move axially synchronously. At the same time, the rotating rod 703 is affected by the first limiting block 704 and the first guide groove 705, so that the rotating rod 703 is rotatably connected to the inner wall of the air supply box 2, and will not actively move axially along the outer wall of the transmission rod 702.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
