The pusher 6 is capable of reciprocating rotation back and forth about a first central axis a extending vertically by the drive mechanism, and a line AB (shown in fig. 6) connecting an end B of the pusher 6 farthest from the central axis a to the central axis a reciprocates in the horizontal plane in sequence along with the rotation of the pusher 6 in the extending direction of the water tank 31 to form a second angle 92, a first angle 91, and a third angle 93 (shown in fig. 8). Wherein, under the first angle 91, the connecting line AB is parallel to the extending direction of the water tank 31, and in this state, the water tank 31 is pushed out under the action of the pushing member 6; and under the second angle 92 or the third angle 93, the connecting line AB intersects with the extending direction of the water tank 31 to form the second angle 92 or the third angle 93, and in this state, a gap is left between the pushing member 6 and the tail of the water tank 31 for pushing the water tank 31 into the water tank seat 32 under the external force, as shown in fig. 3 and 4. In this embodiment, the driving mechanism is a driving motor 4.

Therefore, in the utility model, the pushing member 6 can push out the water tank 31 no matter moves along the second angle 92, the first angle 91 and the third angle 93 in sequence or moves along the directions of the third angle 93, the first angle 91 and the second angle 92 in sequence, and the pushing member 6 does not need to reset after the water tank 31 is pushed out, so that the action process and the control step of pushing out the water tank 31 are simplified, and the service life of the water tank pushing structure is prolonged.

In the present embodiment, the pushing member 6 can rotate back and forth between a second angle 92 and a third angle 93 around the first angle 91, and when the driving motor 4 rotates clockwise, the pushing member 6 rotates clockwise along the directions from the second angle 92 to the third angle 93 to push the water tank 31, and when the driving motor 4 rotates counterclockwise, the pushing member 6 rotates counterclockwise along the directions from the third angle 93 to the second angle 92 to push the water tank 31, so that the pushing member 6 can move between the positions better, and the moving direction of the pushing member 6 along each position can be controlled by controlling the rotating direction of the driving motor 4.

This can avoid the problem that the water tank 31 cannot be smoothly pushed out when the initial position of the pushing member 6 is not at the second angle 92 or the third angle 93. Specifically, when the transmission member 5 moves from any position between the first limiting member 71 and the second limiting member 72 to abut against any one limiting member, the driving motor 4 immediately rotates in the opposite direction, so that the movement of the transmission member 5 can be controlled to control the movement of the pushing member 6, and the problem that the water tank 31 cannot be pushed out smoothly can be avoided.
