The water dispenser is provided with a first limiting wall part 222 and a second limiting wall part 225 which are positioned at the corresponding side parts of the first groove 22, and the first bulge part 11 is provided with a first limiting position and a second limiting position. In the first limit position, the first boss 11 can abut against the first limit wall portion 222, and in the second limit position, the first boss 11 can abut against the second limit wall portion 225. Through the cooperation of first recess 22 and first bellying 11 for the torsion angle of second casing for first casing limits within a certain range, makes the torsion angle of the water pipe 3 of connecting first casing and second casing limit within a certain range, can reduce the risk that the internal diameter of water pipe is undersize, and can reduce the risk that the water pipe harms, warp and drops. In addition, when the water storage tank is used, the first end face of the first shell faces upwards, the second end face of the second shell faces downwards, and the first groove is formed in the second end face of the second shell, so that water cannot accumulate in the first groove.
