The utility model relates to the technical field of washing equipment, in particular to an automatic linen delivery monitoring control mechanism of a linen pressure dehydrator, which comprises a
dehydration basket, one side of the
dehydration basket is fixedly connected with two side
doors, and one side of the
dehydration basket is rotatably matched with a bottom door. By arranging the
piston frame, the square
piston, the lower pressing rod, the U-shaped
pipe, the air guide
assembly and the like, when the bottom door is squeezed downwards, the lower side of the bottom door can squeeze the lower pressing rod, the square
piston is pushed by the lower pressing rod to be in the piston frame, air on the lower side is squeezed, and therefore the bottom door is prevented from being blocked. Air is extruded and then enters the air guide
assembly through the U-shaped
pipe to blow the detection end of the
grating sensor body, so that water spots possibly existing at the detection end of the
grating sensor body are blown off or away, the adverse effects of scattering, absorption and the like of the water spots on optical signals are prevented, and the good optical performance of the detection end is maintained; and thus, the detection precision is improved.
