When installing the filter plate 18, we need to first pull the handle 26 to make the block 22 enter the limit slot 21 so that the block 22 will not block the installation of the filter plate 18, and then install the filter plate 18 to its original position. At this time, release the force on the handle 26, and the spring 24 will release the tension due to the loss of constraint, and the block 22 can be squeezed into the slot 20, so that the filter plate 18 can be firmly fixed inside the water tank 13 for use, thereby improving the filtering efficiency of the filter plate 18.
