[0034] Further, the tail end of the belt body 3 can be tied to the coil spring, and of course it can also be connected to the coil spring through other connecting structures such as threaded fasteners. The head end of the belt body 3 can be tied to the controller 2, and of course it can also be connected to the controller 2 through other connecting methods such as glue bonding.

[0035] In one embodiment, the tightening device 4 includes a rotating shaft disposed in the controller 2, the tail end of the belt body 3 is connected to the rotating shaft, and the head end is connected to the outer wall of the controller 2, and the belt body 3 can be tightened by driving the rotation of the rotating shaft by a motor. Furthermore, a torque sensing system can be provided in the motor, and the motor can be automatically stopped when the torque of the rotating shaft reaches a preset value. Of course, a rotating handle can also be provided on the control to rotate the rotating shaft for adjustment, and when it is rotated to the required tightness, the rotating shaft or handle can be locked by a locking structure, thereby limiting the automatic loosening of the belt body 3. The locking structure can be a pliers structure or can be locked by top pressure through a threaded member.

[0036] In one embodiment, the tightening device 4 includes a buckle, a hidden buckle, a locking buckle, etc. arranged on the belt body 3.

[0037] In some embodiments, the controller 2 includes a housing 21, a second accommodating chamber 211 is provided in the housing 21, an air pump 22, a solenoid valve 23, a control circuit board 24 and a battery 25 are provided in the second accommodating chamber 211, an input end of the solenoid valve 23 is connected to the air pipe 50 joint 81 through the air pipe 50, and an output end of the solenoid valve 23 is connected to the input end of the air pump 22 through the air pipe 50.

[0038] In some embodiments, the air pump 22 may be a piezoelectric ceramic pump, which can reduce weight and noise compared to other air pumps. Of course, other types of air pumps may also be used.

[0039] In some embodiments, a milk suction cavity 5 is provided on one side of the milk suction piece 1, and an air pressure cavity 6 and a milk storage cavity 7 are further provided inside the milk suction piece 1. A flexible diaphragm 10 is provided between the milk suction cavity 5 and the air pressure cavity 6 to separate the two. A flow guide 20 is provided between the milk suction cavity 5 and the milk storage cavity 7 to discharge the milk in the milk suction cavity 5 into the milk storage cavity 7. A milk discharge port 30 connected to the milk storage cavity 7 is provided at the upper part of the milk suction piece 1. The output end of the flow guide 20 is a narrowed port.

[0040] When in use, when the air pump 22 extracts air from the air pressure chamber 6, the air pressure chamber 6 forms a negative pressure, the flexible diaphragm 10 deforms under the external pressure, the space of the air pressure chamber 6 becomes smaller, the milk is sucked out and flows into the milk suction cavity 5, and then flows into the milk storage cavity 7 along the guide member 20 for storage; when the solenoid valve 23 blocks the air pump 22 from extracting air, the air pressure chamber 6 inhales the outside air, the internal and external pressures are consistent, the flexible diaphragm 10 returns to its original state, and the milk suction ends; this cycle continues until a milk suction cycle ends. After the end, the milk is poured out from the milk discharge port 30. Among them, the flexible diaphragm 10 can be breathable silicone, of course, it can also be other materials.

[0041] In some embodiments, the breast pump 1 includes a bra 11 and an outer cover 12 connected to the outside of the bra 11, wherein the bra 11 and the outer cover 12 can be an integrated structure or a split structure connected together by a connecting structure. Specifically, the breast pump 1 includes a bra 11 and an outer cover 12 connected to the outside of the bra 11, the air pressure chamber 6 and the milk storage chamber 7 are both arranged between the outer cover 12 and the bra 11, and the milk suction cavity 5 is arranged at the front end of the bra 11. The bra 11 can be made of silicone or other materials. This design supports both integrated and split structures, and users can choose the most suitable style according to their needs. For parts that need to be cleaned frequently, the split design is more convenient to clean.

[0042] In some embodiments, the front end of the outer cover 12 is provided with an open port 121, the rear inner wall of the outer cover 12 is provided with a first annular tube 122, the bra 11 includes a second annular tube 112 that can be inserted into the first annular tube 122 so that the bra 11 is connected to the outer cover 12, the front end of the second annular tube 112 is provided with a shielding portion 113 for covering the open port 121, the open end of the outer cover 12 is provided with an outer edge 123 extending outward, and the shielding portion 113 is provided with a snap-in groove 114 for inserting the outer edge 123. Among them, the second annular tube fitting 112 and the shielding portion 113 are an integrated structure, and a first annular ridge 1121 can be set on the outer wall of the second annular tube fitting 112 to increase the friction with the inner wall of the first annular tube fitting 122 to limit the second annular tube fitting 112 from coming out. At the same time, the first annular ridge 1121 also has a certain sealing effect. Furthermore, a first card groove for the first annular ridge 1121 to be inserted can also be set at the position on the inner wall of the first annular tube fitting 122 corresponding to the first annular ridge 1121, so that the connection is tighter.

[0043] In some embodiments, a pull ring or handle 1130 is provided on the outer edge of the shielding portion 113 for facilitating the removal of the breast pump 1 .

[0044] In some embodiments, the bra 11 is provided with a frame 1312 to improve its strength. The frame 1312 can be an injection molded part or a metal part. The frame 1312 can provide additional support to ensure that the bra 11 maintains its shape during use and avoids deformation, especially during milk suction, because the negative pressure during milk suction may cause the bra 11 to deform and affect the milk suction effect. The frame 1312 can significantly enhance the overall structural strength of the bra 11 and extend the service life of the product. The design of the frame 1312 can be adjusted according to different needs. For example, the injection molded part can be designed into a more complex shape to adapt to different breast shapes.

[0045] In some embodiments, the outer cover 12 is detachably connected to a cover 8 that can open the air pressure chamber 6, so as to facilitate disassembly and cleaning. The cover 8 is provided with an air pipe 50 joint 81 that is connected to the air pressure chamber 6, and is connected to the air pipe 50 at the input end of the solenoid valve 23 through the air pipe 50 joint 81. The cover 8 can be connected to the outer cover 12 by snap-fit, and of course, can also be connected to the cover 8 by interference fit or other connection structures.

[0046] In some embodiments, there are two breast pumps 1, which just correspond to two breasts of the human body. There are two solenoid valves 23 in the second accommodating cavity 211. One solenoid valve 23 controls one breast pump 1. The output ends of the two solenoid valves 23 are connected to the input end of the air pump 22 through a tee. The output end of the air pump 22 discharges the gas to the outside.

[0047] The two breast pumps 1 are controlled by independent electromagnetic valves 23, respectively, which can realize synchronous breast pumping of both breasts, simulate the natural sucking method of the baby, and improve the efficiency of breast pumping. The working mode of the two electromagnetic valves 23 can be adjusted to realize flexible switching between one side or both sides to meet the needs in different situations. Simultaneous breast pumping on both sides can significantly shorten the total breast pumping time, improve efficiency, and reduce the burden on the mother. The combined design of the two electromagnetic valves 23 and the air pump 22 can ensure the stable operation of the system. Even if one electromagnetic valve 23 fails, the other can still continue to work, providing a backup plan. Through the three-way connection, the air pump 22 can centrally manage the gas flow to ensure the overall reliability of the system. The separately controlled breast pumps 1 can reduce the risk of cross contamination and ensure that the breast pumping environment of each breast is independent and clean.

[0048] The present invention provides a wearable breast pump, comprising a breast pump 1 that can be attached to a breast and a controller 2 that can control the breast pump 1 to suck milk, wherein the breast pump 1 is connected to the controller 2 through an air tube 50, and the controller 2 is provided with a belt 3 for wearing the controller 2 on a human body, and a tightening device 4 that can tighten the belt 3.
