[0024] Embodiment 1: A waterproof structure for a rooftop air conditioner air inlet, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes an air inlet pipe 1, a dustproof plate 2 for dust prevention is arranged in the air inlet pipe 1, a plurality of dustproof holes 3 arranged in a circle are opened on the dustproof plate 2, a shielding assembly for shielding the dustproof holes 3 is arranged in the dustproof plate 2, the shielding assembly includes a shielding plate 4 and a rotating disk 8, and a driving part for driving the shielding assembly is arranged at one end of the shielding plate 4, the driving part includes a rotating rod 5, a connecting rod 6 and a buoy 7, a limiting part for limiting is arranged in the dustproof plate 2, and the limiting part includes a limiting plate 9 and a first return spring 10.

[0025] The dustproof plate 2 is a hollow structure, the rotating disk 8 is rotatably connected to the axial position of the inner wall of the dustproof plate 2, and the dustproof hole 3 runs through both ends of the dustproof plate 2, and a rotating hole is opened at the axial position of the dustproof plate 2 near the end of the air inlet pipe 1, the rotating rod 5 is rotatably connected to the inner wall of the rotating hole, and one end of the rotating rod 5 is fixedly connected to one end of the rotating disk 8.

[0026] A connecting rod 6 is fixedly connected to the outer wall of the rotating rod 5 , and a buoy 7 is fixedly connected to the outer wall of one side of the connecting rod 6 , and the bottom end of the buoy 7 is an arc-shaped structure.

[0027] The shielding plates 4 are arranged in a circle and fixedly connected to the outer wall of the rotating disk 8 , and the number of the shielding plates 4 matches the number of the dustproof holes 3 on the same ring.

[0028] like Figure 3 and Figure 4 As shown, a plurality of circularly arranged limit plates 9 are fixedly connected to the inner wall of the dustproof plate 2, the limit plates 9 are arranged adjacent to the dustproof holes 3, and one end of the limit plate 9 is fixedly connected to a first return spring 10, and the other end of the first return spring 10 is fixedly connected to the outer wall of the shielding plate 4.

[0029] In summary, by setting the baffle plate 4 and the buoy 7, when water enters, the buoy 7 drives the baffle plate 4 to rotate to block the dust hole 3, thereby preventing water from penetrating into the air conditioner from the air inlet, causing damage to the internal components of the air conditioner and reducing its service life.

[0030] Embodiment 2: Based on Embodiment 1, refer to Figure 5 and Figure 6A plurality of linearly arranged sliding holes are provided in the shielding plate 4, the sliding holes and the dustproof hole 3 are located on the same axis, and a second return spring 12 is fixedly connected to the inner wall of one side of the sliding hole, and a sealing block 11 is fixedly connected to the other end of the second return spring 12, and the sealing block 11 is slidably connected to the inner wall of the sliding hole.

[0032] By providing the sealing block 11 and the second return spring 12 , when the shielding plate 4 blocks the dustproof hole 3 , the sealing block 11 can enter the dustproof hole 3 to seal the dustproof hole 3 , thereby improving the waterproof effect.

[0033] The working principle of the utility model is as follows: when water enters the air inlet pipe 1, the buoy 7 is driven by the buoyancy of the water flow to move upward, and the connecting rod 6, the rotating rod 5 and the rotating disk 8 connected to the buoy 7 are rotated and connected to the dustproof plate 2, and then the buoy 7 moves upward to drive the rotating disk 8 to rotate in the dustproof plate 2 through the connecting rod 6 and the rotating rod 5, and the rotation of the rotating disk 8 can drive the shielding plate 4 to rotate synchronously, and the shielding plate 4 rotates to the limit plate 9 and stops rotating due to the limit plate 9, and at this time the shielding plate 4 can shield the dustproof hole 3 , preventing water from flowing into the air conditioner through the air inlet pipe 1. When rainwater is discharged, the baffle plate 4 can be driven to rotate back to its original position under the elastic force of the first return spring 10, and the dustproof hole 3 is no longer blocked; when the baffle plate 4 is rotated to the dustproof hole 3, the sealing block 11 can be driven to slide and be inserted into the dustproof hole 3 under the elastic force of the second return spring 12 to seal the dustproof hole 3, and when the baffle plate 4 is rotated out, the sealing block 11 can be driven back to the sliding hole under the squeezing of the arc edge of the sealing block 11 by the inner wall of the dustproof hole 3.
