Probe purging device

Abstract

The application provides a probe purging device, comprising: a device base, a convex step is formed on the device base, a plunger is formed on the lower plane of the convex step; a purging arm, comprising a vertical air pipe vertically penetrating through the device base and a horizontal air nozzle below the device base and parallel to the surface of the device base, wherein the vertical air pipe and the horizontal air nozzle are connected into an L-shaped structure; a rotation limiting handle, one end of the rotation limiting handle has an axial hole perpendicular to the rotation limiting handle, a notch is formed on the outside of the axial hole, a groove is formed on the axial hole in a direction 90 degrees to the notch on the radial plane of the axial hole, wherein the vertical air pipe of the purging arm vertically penetrates through the device base via the axial hole of the rotation limiting handle above the device base; a spring, vertically arranged between the device base above and the axial hole of the rotation limiting handle and surrounding the outside of the vertical air pipe, wherein the rotation limiting handle controls the horizontal rotation and / or vertical movement of the vertical air pipe to control the alignment of the horizontal air nozzle to the probe for purging.
