Further, the swing rod 40 includes a first connecting rod 401 and a second connecting rod 402, the first connecting rod 401 and the second connecting rod 402 are connected to each other to make the swing rod 40 in a V shape, the bottom part of the installation groove 101 is provided with a pivot joint seat 103, and the connection part of the first connecting rod 401 and the second connecting rod 402 is pivotally connected to the pivot joint seat 103.

[0027] In the embodiment, the bottom plate 20 is provided with a rim plate 202 on both sides, and one end of the swing rod 40 abuts against the bottom surface of the rim plate 202. Further, the first connecting rod 401 abuts against the bottom of the rim plate 202, and the second connecting rod 402 is used for abutting against the bottom of the water tank 70. The weight of the bottom plate 20 is far greater than the thrust force generated by the swing rod 40 due to the self weight, so when the water tank 70 is not loaded into the mounting groove 101, the bottom plate 20 is in the lowest position.

[0028] In the embodiment, a plurality of guide columns 50 are arranged in the mounting groove 101, and the bottom plate 20 is provided with guide holes matched with the guide columns 50, so that the bottom plate 20 moves in the axial direction under the thrust of the swing rod 40, and the highest point of the bottom plate 20 is not higher than the highest point of the guide column 50, avoiding that the bottom plate 20 is thrust by the swing rod 40 to be separated from the guide column 50.
