In this embodiment, the milk storage bottle 20 is mounted on the main body 10, but the milk storage bottle 20 can also be mounted on the tee 30 according to actual needs. The duckbill valve 50 is in communication with the storage bottle 20. The main machine 10 is provided with a pushing positioning structure 12 in the installation cavity 11, and the tee joint 30 is detachably installed in the installation cavity 11 and is abutted against the pushing positioning structure 12. The tee 30 is pushed upwards by the pushing and positioning structure 12 to press the opening end of the air bag 40 to the side wall of the mounting cavity 11.

Because the tee 30 is detachable, the tee 30 can be detached for cleaning and disinfection after use. As shown in fig. 3, after the tee 30 is installed in place, the tee 30 is pushed upwards by the pushing positioning structure 12, the pushing positioning structure 12 applies an acting force F to the tee 30, the second end D2 of the tee 30 presses against the side wall of the installation cavity 11, so that the second end D2 compresses the open end of the air bag 40 to the side wall of the installation cavity 11, the open end of the air bag 40 is tightly attached to the side wall of the installation cavity 11, the sealing effect of the air bag 40 is good, air leakage is not easy, the sealing performance of the breast pump 100 is better, and normal use of the breast pump 100 is ensured.

Preferably, the first end D1 of the tee 30 is integrally formed with the breast shield structure 31, and the breast shield structure 31 extends out of the front end face of the main unit 10. The tee 30 is integrally formed to form the breast shield structure 31, so that the number of parts can be reduced, the structure is more stable, and the assembly and disassembly are more convenient. Of course, the breast shield structure 31 may be manufactured independently according to actual needs, and the breast shield structure 31 may be mounted to the first end D1 of the tee 30.

Wherein the air pump 18 is communicated with the air outlet 153 by an air pipe 111, the electromagnetic valve 19 is communicated with the air inlet 154 by an air pipe 111, the battery 110 is respectively electrically connected with the air pump 18 and the electromagnetic valve 19, the battery 110 supplies power to the air pump 18 and the electromagnetic valve 19, and the battery 110 is preferably a rechargeable battery, but is not limited thereto.

In use, the air pump 18 pumps air in the telescopic air cavity 152 to squeeze out emulsion, and then the electromagnetic valve 19 is opened to enable the telescopic air cavity 152 to be communicated with the atmosphere, and air flows into the telescopic air cavity 152 to enable the air bag 40 to recover. The first housing 16 also has an activation function mode control button, a force/frequency control button, to facilitate control of the breast pump 100.

As shown in fig. 3-5 and 11, the duckbill valve 50 is removably mounted to the third end D3 of the tee 30. The top of the milk storage bottle 20 is convexly provided with a docking station 21, the docking station 21 is provided with a channel 22 communicated with the inner cavity of the milk storage bottle 20, the duckbill valve 50 is penetrated in the channel 22, the docking station 21 is provided with a clamping structure 23, the host 10 is provided with a card matching structure 112, and the milk storage bottle 20 is detachably arranged on the host 10 by the clamping of the clamping structure 23 and the card matching structure 112.

Preferably, the engaging structure 23 and the card distributing structure 112 are engaged with each other in the up-down direction, the engaging structure 23 extends in the front-back direction, and the card distributing structure 112 is a flange structure. After the breast pump 100 is used, the milk bottle 20, the duckbill valve 50, the tee 30 and the bladder 40 can be removed together forward, at which time the main unit 10 can be separated alone, and then the milk bottle 20 can be removed and the milk can be poured through the channel 22. After the milk storage bottle 20 is disassembled, the tee joint 30 is independent, and the tee joint 30 and the duckbill valve 50 can be cleaned at the moment, so that the use sanitation is ensured.

Further, the milk storage bottle 20 comprises a bottle cap 24 and a bottle body 25, wherein the bottle cap 24 is ultrasonically installed on the bottle body 25, so that the bottle cap 24 and the bottle body 25 are in absolute sealing connection, milk leakage is avoided, and the docking station 21 is formed on the bottle cap 24. The bottle body 25 adopts a transparent structure so as to observe emulsion through the bottle body 25, and the bottle body 25 is also provided with capacity graduations so that people can know the sucked emulsion amount by contrasting the graduations.

As shown in fig. 3 and 10, the end of the first end D1 of the tee 30 is provided with a back-off structure 36, the opening end of the air bag 40 is formed with a turned-up structure 41 arranged outwards, and the turned-up structure 41 is buckled on the back-off structure 36, so that the air bag 40 can be more reliably and stably mounted on the first end of the tee 30, and the back-off structure 36 is large in size, so that the turned-up structure 41 is effectively pressed on the gland 15. As can be seen in fig. 3, the back-off structure 36 and the support ring 151 together encase a portion of the airbag 40.

As shown in fig. 10, the airbag 40 includes a ring-shaped structure 42 and a deformation structure 43 protruding downward and connected to the ring-shaped structure 42. The deformation structure 43 is arranged at the middle part of the annular structure 42, and the thin layer structure 44 is arranged at the joint of the annular structure 42 and the deformation structure 43 and at the middle part of the deformation structure 43. It should be noted that the thin layer structure 44 means that the thin layer structure 44 has a relatively smaller thickness than the rest of the airbag 40. As such, when the bellows 152 is evacuated, the lamellar structure 44 deforms first, the motion response is faster, and the remainder deforms slightly slower. The remaining portions of the telescoping air chamber 152 provide support for the lamellar structure 44 due to the small amount of deformation during air intake, allowing the bladder 40 to return faster.

The following briefly describes the operation of the breast pump 100 of the present utility model: before use, the underwear is put on, the breast pump 100 is put into the underwear, the breast shield structure 31 is covered on the breast, and the nipple extends into the nipple sleeve 311, and the breast pump 100 is adjusted so that the front end face of the breast pump 100 is tightly attached to the skin near the breast. Next, after the start function mode button is pressed, the breast pump 100 is started. The air pump 18 draws air from the telescoping air chamber 152, the air bladder 40 collapses, the interior of the tee 30 creates negative pressure, squeezing out breast milk, and the duckbill valve 50 closes. After that, the solenoid valve 19 is opened, the air enters the telescopic air chamber 152, the air bag 40 is restored, the duckbill valve 50 is opened, and the emulsion falls into the milk storage bottle 20, so that the emulsion of the breast can be sucked out by continuous circulation.

After the milk suction is completed, the breast pump 100 is removed from the breast. The tee 30 and the milk bottle 20 are taken out along the front direction of the breast pump 100, at this time, the clamping structure 23 slides out of the matching structure 112, and after the milk bottle 20 is detached, the milk in the milk bottle 20 can be poured out. The tee joint 30 and the duckbill valve 50 are separated, so that the tee joint 30 and the duckbill valve 50 can be cleaned independently, and the use sanitation is ensured. When the utility model is used again, the tee joint 30, the duckbill valve 50 and the milk storage bottle 20 are reloaded.

In fig. 1 and 2, the direction indicated by the arrow X is the left-to-right direction, the direction indicated by the arrow Y is the front-to-rear direction, and the direction indicated by the arrow Z is the bottom-to-top direction, but the present utility model is not limited thereto.
