The further technical scheme of the utility model is: also be provided with the buffer board that extend perpendicular to the direction of the axial line of described cylindrical shell on the edge in the described cylindrical shell, this buffer board is positioned at the below of described vent connection.
Further, the below of described cylindrical shell also is provided with the vortex shield that radially extends along described cylindrical shell.
More preferably, be provided with two described vortex shields in the described cylindrical shell, and two described vortex shields intersect mutually at the place, axle center of described cylindrical shell.
More preferably, described buffer board is between described vent connection and described vortex shield.
The utility model compared with prior art has following advantage: at first, the centrifugal oil eliminator of handpiece Water Chilling Units of the present utility model, filter structure is no longer designed in inside, has reduced the refrigerant gas pressure loss that oil eliminator caused of flowing through.
Secondly, the utility model can improve oil separation efficient:
1, air inlet tube tangentially is arranged on the cylindrical shell, has guaranteed can flow into along the cylinder inboard wall tangential direction when exhaust enters cylindrical shell, increases circular motion radius, and then increases centrifugal force, makes centrifugal separating effect better, improves oil content efficient;
2, the inlet of vent connection is positioned at the below of air inlet tube outlet, can prevent that condensing agent gas directly is deflated the adapter suction and enters refrigeration system;
3, the horizontal positioned of buffer board can intercept eddy current, prevent its will be separated lubricating oil roll again, thereby further guarantee the separative efficiency of oil eliminator;
4, the vortex shield of two orthogonal placements is set, has effectively guaranteed the stable of oil return.
