Connection inside element.For the ordinary skill in the art, above-mentioned term can be understood in reality as the case may be
With the concrete meaning in novel.
As depicted in figs. 1 and 2, the utility model provides a kind of liquid splashing prevention effect reagent needle cleaning device comprising: purge chamber
1 and waste liquid chamber 2, the purge chamber 1 is cylinder, and bottom end opening, and the waste liquid chamber 2 is cylinder, and waste liquid chamber top is opened
Mouthful, the bottom end of the purge chamber 1 is connected with the top of the waste liquid chamber 2, and pin hole 11, institute are offered at the top of the purge chamber 1
11 aperture of pin hole is stated less than the 1 inner cavity internal diameter of purge chamber, 2 bottom of waste liquid chamber is equipped with leakage fluid dram 21, the leakage fluid dram 21
For threaded hole, and seal nipple is housed among waste liquid chamber bottom, waste-solution line is taken out in connection.It is equipped at the top of the purge chamber 1 outer clear
Hair washing 3, the part outer cleaning head 3 is inserted into 1 inner cavity of purge chamber, and is inserted into outside the part in 1 inner cavity of purge chamber and is cleaned
