When the driving motor 51 rotates in the opposite direction and the cover plate 3 moves towards the direction of the tank opening 10 (i.e. towards the right) under the movement of the moving rod 62, the tank base 2 moves along with the moving rod 62 at the same time, so that the tank base 2 moves backwards relative to the tank opening 10, at the moment when the linkage rack 71 is separated from the second transmission gear 73, the tank base 2 moves into position and is stationary, and the cover plate 3 continues to move towards the direction of the tank opening 10 until the tank opening 10 is completely shielded.

Further, in order to allow the tank base 2 to be smoothly moved forward and backward and moved in or out of the tank port 10, a limit guide 8 for guiding the tank base 2 to move forward and backward is provided on the bottom surface of the tank base 2 and the upper surface of the mounting plate 131. The limit guide structure 8 includes a guide rod 81 fixed to the bottom surface of the water tank base 2 and extending in the front-rear direction, and a guide sleeve 82 fixed to the upper surface of the mounting plate 131 and extending in the front-rear direction, and the front end of the guide rod 81 is fixed to the bottom surface of the water tank base 2 through a fixing block 83 while the other part of the guide rod 81 is suspended, and when the front end of the guide sleeve 82 abuts against the fixing block 83, the water tank port 10 is completely exposed, and the water tank base 2 is moved out of place with respect to the water tank port 10. Thereby enable water tank seat 2 and remove along the fore-and-aft direction more steadily under spacing guide structure 8's effect, in addition, under water tank seat 2 shifted out the state of targetting in place, can carry on spacingly through fixed block 83 to water tank seat 2, avoid water tank seat 2 to drop.

The working process of the utility model is as follows:

in the initial state, the cover plate 3 completely covers the tank port 10, and the tank base 2 is hidden and stored behind the cover plate 3. When the water tank 21 needs to be taken, the driving motor 51 rotates positively to drive the screw rod 52 to rotate, further drive the moving rod 62 to move towards the left, the roller 31 slides out of the limiting sliding groove 32, the cover plate 3 and the water tank opening 10 are staggered from front to back, the roller 31 slides towards the left along the guide surface 33, and the water tank opening 10 is exposed gradually. When the left end of the linkage rack 71 is engaged with the first transmission gear 72, the action of the linkage rack 71 drives the second transmission gear 73 to rotate, and further drives the first transmission gear 72 to rotate, so that the first transmission gear 72 drives the transmission rack 74 to move forward, and further drives the water tank base 2 to extend relative to the water tank base 2, and when the right end of the linkage rack 71 is engaged with the second transmission gear 73, the water tank base 2 is moved out of place, at the moment, the driving motor 51 stops rotating, and a user can take the water tank 21 on the water tank base 2.

After the water tank 21 is filled with water, the water tank is placed back to the water tank seat 2, the driving motor 51 is rotated reversely to move the moving rod 62 to the right, the linkage rack 71 drives the second transmission gear 73 to rotate, so that the water tank seat 2 is driven to move backwards through the first transmission gear 72 and the transmission rack 74, when the linkage rack 71 is separated from the second transmission gear 73, the water tank seat 2 moves in place and is static, and the cover plate 3 continues to move towards the water tank opening 10 until the water tank opening 10 is completely shielded.
