The invention relates to the technical field of maternal and child products, and discloses a double-pump sequential milk sucking device which comprises a liquid transferring box, a milk sucking
nozzle is movably connected to the upper portion of the liquid transferring box, a milk sucking cover is movably connected to the outer surface of the milk sucking
nozzle, a liquid transferring
pipe is movably connected to the end, away from the milk sucking
nozzle, of the liquid transferring box, The side of the
liquid transfer pipe away from the liquid transferring box is movably connected with a milk storage
bottle, through cooperative use of a fixing sleeve, a limiting sleeve, a rotating shaft, a moving block, a connecting rod, a limiting plate and a
rotating disc, milk can be sequentially sucked from the
left breast and the
right breast in the milk sucking process, on one hand, the situation that continuous milk sucking increases the discomfort during milk sucking is avoided, and on the other hand, it is avoided that the position of the suction nipple needs to be adjusted left and right during milk suction, more time and labor are saved, the working efficiency during milk suction is improved, through cooperative use of a push rod, a cross rod, the
pinion, a rotating rod and a suction nipple, in the milk suction process, the negative pressure of milk suction is kept consistent, and the situation that the negative pressure is too large or too small, and the milk suction effect is affected is avoided.
