When the water tank 11 is put into place during the retraction of the water tank 11, the return spring 73 is compressed, and the trigger 72 is driven to move towards the rear side of the water tank base 12, so that the trigger end 722 of the trigger 72 is separated from the contact of the micro switch 71, the micro switch 71 is turned off, and the water tank 11 is pushed into place. If the water tank 11 is not pushed in place, the trigger end 722 of the trigger 72 keeps abutting against the contact of the micro switch 71, the micro switch 71 is turned on, and the position state of the water tank 11 can be judged according to the opening and closing state of the micro switch 71. In addition, when the water tank 11 is pushed to the proper position, the slide bar 3 is locked by the guide locking mechanism 6, so that the contact end 721 of the trigger 72 is not in direct contact with the water tank 11 but in contact with the contact surface 3100 of the slide bar 3, and the problem that the water cannot be pumped up or leaks due to the fact that the return spring 73 applies force to the water tank 11 and the water outlet of the water tank 11 is not properly combined with the water outlet joint can be avoided.
