That is, the high liquid level detector 6 is indirectly installed on the liquid outlet end of the upper liquid tube 2 through the liquid outlet nozzle 7. At the same time, based on the fact that the liquid outlet channel 721 is located on the side of the liquid outlet part 72 and the liquid outlet channel 721 is arranged obliquely downward, when the liquid is discharged, the liquid sprayed from the liquid outlet channel 721 can be guided by the liquid outlet channel 721 to spray obliquely downward to the liquid containing cavity 11. The liquid will not splash onto the high liquid level detector 6 and cause misjudgment, and the structural reliability is higher.

[0062] See also Figures 5 - 6 In one embodiment, both sides of the liquid outlet 72 have liquid outlet channels 721 to reduce the liquid outlet pressure and make the liquid outlet more gentle, which can effectively avoid the splashing of droplets in the liquid outlet channel 721 and reduce the probability of droplets splashing to the high liquid level detector 6.
