The lifting assembly is used for driving the water pump 200 to lift to the upper side of the drawing water tank 100 when the drawing water tank 100 is pulled out of the accommodating cavity, when the water pump 200 is lifted to the upper side of the drawing water tank 100, the drawing water tank 100 is pulled out of the accommodating cavity and cannot be interfered by the water pump 200, and when the drawing water tank 100 is inserted into the accommodating cavity, the water pump 200 is driven to descend to the inside of the drawing water tank 100, specifically, the water pump 200 is lowered to the lower side of the water level line 500 of the drawing water tank 100.

The lifting assembly is connected with the water pump 200 through the elastic piece 300, so that the lifting assembly is elastically connected with the water pump 200, when the water pump 200 works, the elastic piece 300 can absorb vibration generated by the water pump 200, the effect of reducing noise is achieved, and the elastic piece 300 can also prevent the vibration of the water pump 200 from being transmitted to the lifting assembly.

In operation, when the pull water tank 100 needs to be filled with water, the pull water tank 100 is pulled out from the accommodating cavity. When the drawing water tank 100 is drawn out from the accommodating cavity, the lifting assembly drives the water pump 200 to be lifted to the upper side of the drawing water tank 100, so that the drawing water tank 100 is drawn out from the accommodating cavity without interference of the water pump 200. When the pull-out water tank 100 is reinserted into the receiving cavity after filling water, the lifting assembly drives the water pump 200 to gradually descend into the pull-out water tank 100 and below the water line 500. When the water pump 200 operates and generates vibration noise, the elastic member 300 can absorb the vibration generated from the water pump 200, thereby achieving the effect of reducing the noise.

In some embodiments of the present utility model, as shown in fig. 1 and 3, the elastic member 300 includes a buffer spring 310, one end of the buffer spring 310 is connected to the lifting assembly, and the other end is fixedly connected to the water pump 200. Specifically, the buffer spring 310 is vertically disposed, and has an upper end connected to the lifting assembly and a lower end fixedly connected to the water pump 200. The buffer spring 310 can elastically connect the lifting assembly and the water pump 200, thereby absorbing vibration generated from the water pump 200 and preventing the vibration of the water pump 200 from being transferred to the lifting assembly.

In a further embodiment of the present utility model, as shown in fig. 1 and 3, the number of the buffer springs 310 is plural, and the provision of plural buffer springs 310 can further increase the vibration and noise reduction effect on the water pump 200.

In some embodiments of the present utility model, as shown in fig. 1 and 2, a lifting assembly is disposed in the receiving chamber, the lifting assembly including a trigger lever 440, a connecting rod 420, and a lifting spring 410.

The water pump 200 is connected to the other end of the connection rod 420 through the elastic member 300. When the connection rod 420 rotates upward by a preset angle, the water pump 200 rises above the drawing water tank 100. One end of the lifting spring 410 is fixedly connected with the housing, and the other end is fixedly connected with the connecting rod 420. Specifically, one end of the lifting spring 410 is fixedly connected with the top of the accommodating chamber. The lifting spring 410 is configured to drive the connecting rod 420 to rotate upwards by at least a preset angle when contracting, specifically, when the lifting spring 410 is of a normal length, the connecting rod 420 enables the water pump 200 to be located above the drawing water tank 100.

One end of the trigger lever 440 is fixedly connected with one end of the connecting rod 420, the trigger lever 440 and the connecting rod 420 rotate synchronously, the trigger lever 440 is abutted with the drawing water tank 100 to prevent the connecting rod 420 from rotating upwards, and the lifting spring 410 is in a tensile power storage state for enabling the connecting rod 420 to rotate upwards by at least a preset angle, when the drawing water tank 100 is fully inserted into the accommodating cavity, the drawing water tank 100 and the trigger lever 440 are abutted with the connecting rod 420 to prevent the connecting rod 420 from rotating upwards, so that the lifting spring 410 is in the tensile power storage state. Further, the trigger lever 440 and the connecting lever 420 are integrally formed.

In operation, when the pull water tank 100 is positioned in the receiving chamber, the pull water tank 100 and the trigger lever 440 abut against each other to prevent the connecting rod 420 from rotating upward, thereby maintaining the water pump 200 in the pull water tank 100. When the drawing water tank 100 is drawn out from the accommodating cavity, the drawing water tank 100 and the trigger lever 440 are not abutted any more, and the pushing force applied to the trigger lever 440 is withdrawn, so that the lifting spring 410 is released. The lifting spring 410 contracts to release the elastic force, thereby driving the connection rod 420 to rotate upward by a preset angle, and thus driving the water pump 200 to be lifted above the drawing water tank 100. When the drawing water tank 100 is reinserted into the receiving cavity, the drawing water tank 100 contacts with the trigger lever 440 and drives the trigger lever 440 to rotate downward, thereby driving the connecting rod 420 to rotate downward synchronously, and thus the lifting spring 410 stretches the power storage until the water pump 200 descends to the initial state height.

In some embodiments of the utility model, as shown in fig. 1 and 2, the lift assembly further includes a shaft 430. The rotation shaft 430 is disposed at an inner end of the receiving chamber above the pull-out water tank 100. One end of the connection rod 420 is rotatably disposed on the rotation shaft 430.
