The utility model discloses a kind of for deodorizing
agent detection devices, including electronic
nose main body, the right side of the electronic
nose main body is fixed with two pipeline fixing mechanisms, the pipeline fixing mechanism includes plug, the outside of the plug is equipped with fixed cylinder, the outside wall of the fixed cylinder is fixed with multiple half-arc blocking rings, the right side of the fixed cylinder is fixed with multiple elastic sheets.The for deodorizing
agent detection device, insert air inlet
pipe and air outlet
pipe on plug, pull moving cylinder, extrude groove
extrusion extrusion block,
extrusion block extrusion elastic sheet, elastic sheet extrusion air inlet
pipe or air outlet pipe, clamp air inlet pipe or air outlet pipe, then rotate moving cylinder, stop block is inserted between two half-arc blocking rings, left side half-arc blocking ring stops stop block, limit stop block and moving cylinder movement, so it is convenient to fix air inlet pipe and air outlet pipe, without through multiple rotation extrusion component, make extrusion component move extrusion air inlet pipe and air outlet pipe.
