In addition, the milk storage bin 2 and the horn cover 141 of the breast pump can be detached independently, so that the breast pump is convenient to clean and is safer and more sanitary.

As shown in fig. 3-6, the three-way milk suction cavity 131 is provided with a connecting convex part 134 and a connecting clamping groove 133, the horn cover 141 is provided with a connecting groove 145, the horn cover 141 penetrates through the three-way milk suction cavity 131 and is clamped with the connecting groove 145 through the connecting convex part 134 to realize fixation, and the connecting clamping groove 133 is located at the lower end of the three-way milk suction cavity 131 and is clamped with the milk storage bin 2. The utility model discloses a shape of breast can be laminated better to loudspeaker cover 141, and simultaneously through connecting protruding piece 134 and coupling groove 145, realize with the sealing connection of tee bend breast suction chamber 131 to ensure the gas tightness of breast suction in-process. Meanwhile, the device is convenient to use and install in daily life. This breast pump increases the negative pressure and takes place the space through setting up tee bend breast pumping chamber 131, and then can improve the negative pressure effect, improves the suction scope, is favorable to forming different suction modes, increases user experience.

As shown in fig. 5, in which the dotted line indicates the suction flow trajectory and the solid line indicates the milk flow direction. When the main body 110 is operated, air in the negative pressure chamber 120 is pumped, so that negative pressure is formed in the three-way milk sucking chamber 131 and is transmitted to the horn cover 141 through the negative pressure milk outlet 143. Under the action of negative pressure in the breast pump, milk flows in from the milk suction port 142, then flows to the outlet 132 of the three-way milk suction cavity 131 through the negative pressure milk outlet 143, and flows to the duckbill one-way valve 3. The negative pressure milk outlet 143 is located above the outlet 132 to better facilitate the flow of milk to the duckbill check valve 3.

As shown in fig. 7-10, the duckbill check valve 3 of the present breast pump is positioned between the breast opening 142 and the milk storage chamber 2. The three-way milk sucking cavity 131 is provided with a connecting clamping groove 133, the milk storage bin 2 is provided with a corresponding clamping block 220, and the connecting clamping groove 133 is clamped with the clamping block 220. The utility model discloses a 3 exits of duckbilled check valve are flat shape, and 3 entrances of duckbilled check valve are connected with negative pressure milk outlet 143, and flat shape export 132 stretches into in storing up milk storehouse 2. The utility model discloses a set up connecting slot 133 at tee bend loudspeaker cover 141, set up screens piece 220 storing up milk storehouse 2, can inhale milk chamber 131 below at the tee bend with storing up 2 joints in milk storehouse, the mode daily use that the trip is connected is more convenient and fast, and duckbill check valve 3 can prevent to suckle and flow back, and the storage effect is better. And because duckbilled check valve 3 is soft silica gel, and the one end of being connected with tee bend breast milk chamber 131 is equipped with sealing strip 310, and sealing strip 310 and export 132 looks butt, therefore the leakproofness is also better.

As shown in fig. 11-15, the negative pressure bin 120 includes a negative pressure cavity 121, a negative pressure bin body 122 and an air suction hole 123, the negative pressure cavity 121 is connected to the host 110, the air suction hole 123 is located on the negative pressure cavity 121 and is hermetically and communicatively connected to the negative pressure bin body 122, and the negative pressure bin body 122 is connected to the three-way horn cover 141. The utility model discloses a negative pressure storehouse body 122 overlaps in tee bend breast milk suction cavity 131 to because the two sealing connection. The program is preset in the main unit 110, and when the breast pump is started, the main unit 110 can pump out the air in the negative pressure chamber body 122 through the air pumping hole 123, so that the negative pressure chamber body 122 can deform, negative pressure is formed in the three-way milk pumping chamber 131, and the air flows in from the negative pressure milk outlet 143 to generate suction. Meanwhile, the negative pressure chamber 120 is designed in an integrated manner, so that even if a small amount of milk is sucked into the cavity of the three-way milk suction chamber 131 due to suction in the milk suction process, the milk cannot contact with a circuit device in the milk suction device, the milk suction device is safer, and after the three-way horn cover 141 is detached, the outer wall of the negative pressure chamber body 122 and the inner wall of the three-way milk suction chamber 131 can be directly scrubbed, so that the milk suction device is more sanitary in daily use. The negative pressure bin 122 is provided with an air bin 124 and a reinforcing rib 125 fixedly connected with the air bin 124, the three-way milk suction cavity 131 is sleeved outside the air bin 124, and the horn cover 141 passes through the three-way milk suction cavity 131 and is positioned between the air bin 124 and the three-way milk suction cavity 131 (namely, the negative pressure space 150). Under the influence of negative pressure, the gas bin 124 will contract toward the center of the negative pressure bin 122, so as to form negative pressure suction in the three-way milk sucking cavity 131. Meanwhile, the reinforcing ribs 125 can better help the air bin 124 to restore the shape.

In addition, one end of the horn cover 141 passing through the three-way milk sucking cavity 131 is provided with a massage structure 144, the massage structure 144 is connected with the air bin 124 in an abutting manner, and the massage structure 144 is an inward concave inclined plane. When the gas chamber 124 contracts to the center, the massage structure 144 can be extruded, and simultaneously, because the horn cover 141 is made of soft material, under the milk sucking state, the massage structure 144 can generate inward extrusion along with the contraction of the gas chamber 124, so that the nipple can be slightly pressed for massage, and the comfortable sensation of the product can be better improved.

The utility model discloses a theory of operation: when the three-way milk sucker is used, the three-way horn cover 141 is sleeved on the host 110, the negative pressure cavity 121 is sleeved in the three-way milk sucking cavity 131, one end of the duckbill one-way valve 3 is sleeved below the three-way milk sucking cavity 131, the other end of the duckbill one-way valve extends into the milk storage bin 2, the milk storage bin 2 is clamped on the connecting clamping groove 133, and the milk sucker is installed. When in use, the three-way horn cover 141 is attached to the breast, and the interior of the breast pump is in a sealed state. The host 110 is started, air in the negative pressure cabin 122 is pumped away, a negative pressure state is formed in the three-way milk suction cavity 131, milk is pumped out through the negative pressure milk outlet 143 and flows to the outlet 132 of the three-way milk suction cavity 131, and the milk flows into the milk storage cabin 2 through the duckbill one-way valve 3 to be stored. When the milk needs to be poured out, the milk storage bin 2 is only needed to be dismounted and poured into other containers.
