[0027] Refer to Figures 1-5, an embodiment provided by the utility model: a ceiling ventilation fan, which includes a ventilation frame 1. A ventilation groove 2 is arranged inside the ventilation frame 1. A ventilation fan 3 is arranged inside the ventilation groove 2. And a first grille frame 4, a second grille frame 5 and a protective filter screen 6 are respectively arranged from top to bottom inside the ventilation groove 2. The first grille frame 4 is in the form of a horizontally inclined grille, and the second grille frame 5 is in the form of a vertical grille. The two can play an isolation and protection effect on the entire ventilation frame. The protective filter screen 6 can play a filtering and protection role at the ventilation position, which can not only filter out dust and sundries, but also prevent some flying insects, crawling insects, etc. from entering the internal structure. A fixed notch 7 is arranged at the corresponding position of the bottom of the ventilation frame 1 and the ventilation groove 2. A shielding plate 8 is nested inside the fixed notch 7. The setting of the shielding plate 8 can play a closed protection role when the entire ventilation fan is not working. A collection groove 9 is arranged at the top of the shielding plate 8. The position of the collection groove 9 corresponds to the position of the ventilation groove 2. In this way, combined with the entire structure, it can conveniently receive the dust and impurities cleaned from the filter screen structure and avoid the situation of dust scattering. A rotating block 10 is rotatably connected inside the collection groove 9. A rotating frame 11 is fixedly connected to the rotating block 10. A cleaning brush 12 is arranged at the top of the rotating frame 11. The cleaning brush 12 is arranged in a fitting manner with the protective filter screen 6. A rotating block 13 is fixedly connected to the central axis of the rotating block 10 and at the position below the shielding plate 8. A crank 14 is arranged on the rotating block 13. Grasping the crank 14 and revolving around the center of the rotating block 13 can drive the rotation of the rotating block 13. The rotating block 13 drives the rotation of the rotating block 10. The rotating block 10 drives the rotation of the rotating frame 11. The rotating frame 11 drives the cleaning brush 12 to clean the protective filter screen 6, improving the convenience of cleaning the filter screen structure. A locking mechanism is arranged between the shielding plate 8 and the fixed notch 7.

[0028] A storage groove 15 is arranged at the bottom of the rotating block 13. One end of the crank 14 is rotatably connected to the inner wall of the storage groove 15 near one end. The setting of the storage groove 15 can rotate and store the crank 14 therein when it is not in use to avoid being accidentally touched.

[0029] The locking mechanism includes a fixing groove 16 provided on the inner wall of the fixed notch 7 and a locking groove 19 provided on the shielding plate 8. A locking block 17 and a spring 18 are respectively arranged in the fixing groove 16. An activity groove 20 is provided on the inner wall of the fixing groove 16. A moving block 21 which is slidably connected with the activity groove 20 is fixedly connected to the locking block 17. An operating block 22 is fixedly connected to the bottom of the moving block 21. The locking block 17 and the locking groove 19 are arranged in an inserted and matched manner, and one side of the bottom of the locking block 17 is in an inclined surface form. There are two locking mechanisms which are symmetrically arranged on both sides of the shielding plate 8. During installation, the shielding plate 8 is snapped into the fixed notch 7. When snapping in, the shielding plate 8 presses against the inclined surface position of the locking block 17. Through the pressing, the locking block 17 will slide and contract and compress the spring 18. When the shielding plate 8 is snapped into the fixed notch 7, the spring 18 resets and pushes the locking block 17 to snap into the locking groove 19, and thus the installation of the locking mechanism can be completed, enabling the shielding plate 8 to be stably snapped into the fixed notch 7 and closing the ventilation groove 2. During disassembly, the operating block 22 is pushed, and the operating block 22 drives the locking block 17 to leave the locking groove 19 through the moving block 21, and thus the disassembly operation of the locking mechanism can be completed.

[0030] Working principle: When using the ceiling ventilation fan, when the ventilation fan 3 works, it can drive the air flow to flow, so that the air flow can flow through the ventilation groove 2, and thus the effect of ventilation can be achieved. When the ventilation fan is not in use, the shielding plate 8 is snapped into the fixed notch 7 and fixed through the locking mechanism, and thus the ventilation groove 2 can be closed. When the protective filter net 6 needs to be cleaned, the shielding plate 8 is installed in the fixed notch 7 in the same way. By grasping the rocking handle 14 and revolving around the center of the rotating block two 13, the rotating block two 13 can be driven to rotate. The rotating block two 13 drives the rotating block one 10 to rotate. The rotating block one 10 drives the rotating frame 11 to revolve. The rotating frame 11 drives the cleaning brush bristles 12 to clean the protective filter net 6. The dust and impurities cleaned fall automatically into the collection groove 9. Similarly, the shielding plate 8 is disassembled, and thus the dust and impurities in the collection groove 9 can be conveniently cleaned, improving the convenience of the structure cleaning.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
