In the embodiments of the present invention, when negative pressure pump 5 to valve body 2 carry out negative-pressure ward when, this first go out milk valve 4
It opens, second, which goes out milk valve 6, closes；When negative pressure pump 5 carries out negative pressure release to valve body 2, first closing of milk valve 4 out, second goes out
Milk valve 6 is opened.
That is, going out two of milk valve 4 when first goes out milk valve 4 and second goes out milk valve 6 and be connected with valve body 2 for first and opening and closing
Valve block 41 protrudes into the first chamber 242 of valve body 2, and makes the first sealed connection of milk arrival end 21 for going out milk valve 4 and valve body 2,
Second goes out one end milk outlet end 22 for being connected to valve body 2 by going out milk portion pipeline 25 of milk valve 6, this second goes out the two of milk valve 6
A folding valve block 61 is located at the outside of valve body 2.
When negative pressure pump 5 carries out negative-pressure ward by the aspiration end 23 of valve body 2 and the valve chamber 24 of valve body 2, shape in valve chamber 24
At condition of negative pressure, second two folding valve blocks 61 for going out milk valve 6 can be close together, and outside air can not go out milk valve 6 through second
Into in valve body 2, negative pressure can only go out milk valve 4 through first and pass at breast cup 3, and then realizes and pump out the milk in breast,
It ensure that only one input port in negative pressure input process, pressure will not be depleted, insufficient pressure when preventing from sucking；Work as negative pressure pump
When 5 pairs of valve bodies 2 carry out negative pressure release, that is, bowl-type suction plug 51 moves downward in negative pressure pump 5, the negative pressure quilt in the valve chamber 24
Release, at the same with the variation of pressure, it pushes the milk being trapped in valve chamber 24 to go out milk valve 6 through second and flows out, and first goes out milk
Valve 4 protrudes into the design structure in valve body 2 using by two folding valve block 41, during ensure that the release of 24 negative pressure of valve chamber,
First goes out the closure of milk valve 4, avoids gas and flows back away from breast cup 3, and can only go out milk valve 6 from second and discharge, in turn
The speed that ensure that milk outflow avoids milk reflux from polluting；Meanwhile gas all goes out milk valve 6 through second downwards and flows out,
The gas of outflow can strut milk bag 8, and this design is highly suitable for cooperating the use of sterile milk bag, and milk is made smoothly to flow into milk
In bag 8.
In the embodiments of the present invention, first go out milk valve 4 each folding valve block 41 thickness and second go out milk
The thickness of each folding valve block 61 of valve 6 is 0.5cm~2cm.Further, first go out milk valve 4 two folding valve blocks 41 it
Between angle theta be 30 °~60 °, the second angle thetas gone out between two of milk valve 6 folding valve blocks 61 are 30 °~60 °.
In the embodiments of the present invention, multiple fins 111 are equipped on the outer wall for the vent line 1 that sucks.Those
Fin 111 can guarantee that the threeway mechanism of the utility model will not deform, and reduce in the state that valve body 2 is in negative pressure work
Negative pressure loss.
