The side of the jamming slot 215 facing said second turning point 227 is provided with a guiding edge 266.
When the water tank seat is installed, a user pushes the water tank seat into the shell bracket 204 by applying a certain pushing force, the water tank seat drives the sliding block to move inwards, at the moment, the elastic sheet is stretched, the second track 225 moves inwards, namely, the second connecting part 220 moves forwards relative to the second track 225, when the water tank seat moves to the second rotating point 227, the sliding block cannot move forwards continuously due to the blocking of the second rotating point 227, the pushing force of the user on the water tank seat is removed at the moment, the elastic sheet gives an outward pulling force to the sliding block, the sliding block (the second track 225) moves outwards under the driving of the pulling force, the second connecting part 220 slides into the clamping groove 215 along the guide edge 266 on the clamping groove 215, at the moment, the sliding block cannot move outwards due to the blocking of the clamping groove 215, and therefore, the installation of the water tank seat in place and clamping are realized.
When the water tank base needs to be ejected, a user applies a certain pushing force to the water tank base, the water tank base 201 drives the slider 205 to move inwards, at this time, the second connecting portion 220 moves forwards relative to the slider, enters the first track 224 and moves in the first track 224 under the guiding action of the third guide piece 228 when moving to the third guide piece 228, when moving to the first rotating point 226, the slider (the first track 224) cannot move forwards continuously due to the blocking of the first rotating point 226, and at this time, the pushing force of the user to the water tank base is removed, the elastic piece gives an outward pulling force to the slider, the slider (the first track 224) moves outwards under the driving of the pulling force, the second connecting portion 220 slides out along the first track 224, and at this time, the water tank base is ejected.
As shown in fig. 6, a fixing block 229 is disposed on the housing bracket 204, a main body of the latch hook is located between the housing bracket 204 and the fixing block 229, and the latch hook is fastened to the housing bracket 204 through the fixing block 229.
