The purification tube 511 is connected to the connector 524 of the clamping plate 5241, and then the purification tube 511 is connected to the slider 523 to fix the purification tube 511. Through the round shell 5242 set on the clamping plate 5241 and the positioning column 5245 slidably set on the round shell 5242, when the staff installs the purification tube 511, they first place the bottom end of the purification tube 511 on the positioning column 5245, and press the positioning column 5245 downward during the placement process. At this time, the pressure generated by the positioning column 5245 can press down the spring 1 5244. At this time, the overall height of the connector 524 is reduced, so that the upper end of the purification tube 511 is The slider 523 in the groove 521 at the upper end of the positioning frame 51 is separated, which makes it convenient for the staff to disassemble and replace the purification tube 511. By setting the circular plate 1 5251 in the positioning column 5245 and the spring 2 5252 connected between the positioning column 5245 and the circular plate 1 5251, it is achieved that when the staff places the purification tube 511 in the positioning column 5245, the pressure generated can be pressed down by the telescopic column 52431, and the telescopic column 52431 moves to press down the spring 2 5252.
