The drain surface 40 is provided with a first track 41, a second track 42 and a third track 43 in sequence along the direction away from the drain outlet 44. The first track 41 is connected to the first fan frame 11 through corresponding rollers, the second track 42 is connected to the second fan frame 12 through corresponding rollers, and the third track 43 is connected to the third fan frame 13 through corresponding rollers. The first fan frame 11 is equipped with a first glass body 21, the second fan frame 12 is equipped with a second glass body 22, and the third fan frame 13 is equipped with a mesh 23.

[0052] The first track 41, the second track 42 and the third track 43 are all roughly T-shaped. The first track 41 is provided with a first side 411, a second side 412 and a first column 413. The first column 413 is connected to the drainage surface 40.

[0053] The second track 42 is provided with a third side 421, a fourth side 422 and a second column 423, and the second column 423 is connected to the drainage surface 40;

[0054] The third track 43 is provided with a fifth side 431, a sixth side 432 and a third column 433, and the third column 433 is connected to the drainage surface 40;

[0055] The first column 413, the second column 423 and the third column 433 are all provided with corresponding drainage hole structures, and water flows through the drainage surface 40 to the drainage outlet 44.

[0056] refer to Figures 3 to 5 The first seal 5 is located on the first side 411 of the first track 41 near the drain outlet 44;

[0057] The first seal 5 is provided with a first shaft 53, and the first side 411 is provided with a first shaft hole 414 that mates with the first shaft 53;

[0058] The first sealing element 5 is a split structure. It can be detachably assembled to the lower track profile 4 through the cooperation of the first shaft 53 and the first shaft hole 414. The first sealing element 5 is located above the drain outlet 44 and on one side of the first track 41. It can cover the drain outlet 44 and the first track 41 to a certain extent, thereby improving aesthetics and sealing.

[0059] Furthermore, the split structure of the first seal 5 facilitates processing and manufacturing. For example, it facilitates the processing of the drainage hole structure of the first seal 5 and the first track 41, that is, after the first seal 5 and the first track 41 are processed, they are assembled together.

[0060] If the first sealing element 5 and the lower track profile 4 are integrally formed, the first sealing element 5 will slightly obstruct the processing of the first track 41 when machining the drainage hole, making alignment difficult and processing inconvenient.
