A groove 4 is provided on the back of the door panel 2, and an empty groove 5 is provided on the top wall of the groove 4. A threaded rod 6 is rotatably connected to the inner top wall of the empty groove 5, and a threaded sleeve 7 is threadedly sleeved on the surface of the threaded rod 6. A pressure plate 8 is fixedly connected to the bottom end of the threaded sleeve 7, and a row of fixing rods 9 are fixedly connected to the lower surface of the pressure plate 8. A fixing block 10 is fixedly connected to the upper surface of the outer shell of the ventilation fan 3, and a row of fixing holes 11 are provided on the upper surface of the fixing block 10, and the fixing holes 11 match the fixing rods 9.

[0025] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the back side of the door panel 2 is rotatably connected to a rotating rod 12, one end of the rotating rod 12 extends to the inside of the empty groove 5 and is fixedly connected to a first bevel gear 13, and a second bevel gear 14 is fixedly sleeved on the surface of the threaded rod 6. The first bevel gear 13 and the second bevel gear 14 are meshed with each other, and the ventilation fan 3 can be easily and quickly installed and disassembled by rotating the rotating rod 12.

[0026] Embodiment 3: The difference between this embodiment and embodiment 1 is that a row of plug rods 15 are fixedly connected to the lower surface of the outer shell of the ventilation fan 3, and a row of plug holes 16 are provided on the inner bottom wall of the groove 4. The plug rods 15 match the plug holes 16, which facilitates the positioning of the ventilation fan 3 and facilitates installation and disassembly.

[0027] Embodiment 4: The difference between this embodiment and embodiment 1 is that, a mounting frame 17 is fixedly connected to the back of the door panel 2, the mounting frame 17 is located around the groove 4, and a filter plate 18 is detachably inserted inside the mounting frame 17, so that the air can be filtered during ventilation, and the filter plate 18 can be quickly replaced.
