Internal bottom.
Cleaning process of the present utility model：
After needle tubing 200 sucks reagent, during running up, cleaning fluid enters cleaning container by feed pathway 103
102, flowed out after being cleaned to the outer wall of needle tubing 200 by liquid outlet channel 101；Whole process in order to ensure cleaning fluid not from except
Gap outflow cleaning hardware body 100 outside liquid outlet channel 101, is reserved suitable between needle tubing 200 and cleaning hardware body 100
When gap, sealed using the surface tension of liquid.
The wiper mechanism that can be seen that the present embodiment and provide is described in detail to of the present utility model with reference to more than, including it is clear
Hardware body 100 and the needle tubing 200 moved up and down relative to cleaning hardware body 100 are washed, and needle tubing 200 is through cleaning part sheet
Body 100；Gap setting between the outer wall of needle tubing 200 and cleaning hardware body 100 is 0.1mm~0.5mm；Clean hardware body
100 are internally provided with the feed pathway 103 entered for cleaning fluid and the liquid outlet channel 101 for cleaning fluid outflow, and feed liquor leads to
It is provided with cleaning container 102 between road 103 and liquid outlet channel 101, and cleaning container 102 is respectively with feed pathway 103 and going out liquid
Passage 101 connects.In cleaning process, cleaning fluid enters in cleaning container 102 to enter needle tubing 200 by feed pathway 103
Row cleaning, at the same time cleaning fluid can also be flowed out by liquid outlet channel 101, and cleaning fluid will not be made to residue in cleaning container 102
It is internal；, can not only again because the gap setting between the outer wall of needle tubing 200 and cleaning hardware body 100 is 0.1mm~0.5mm
Liquid is formed the globule in the outer wall of needle tubing 200, and surface tension of liquid can also be utilized, liquid is formed liquid in gap close
Sealer, prevent fluid seepage；Therefore wiper mechanism has the advantages of simple in construction, avoids cleaning fluid from being formed during use
Liquid is hung, so as to solve the problems, such as easily to form cross pollution.
