Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a wearable, hands-free breast pump. Background Technology

[0002] Breast pumps are a common maternal and infant product. When newborns are in the first 1-3 months after birth and cannot suckle from their mother's nipple to obtain breast milk, a breast pump is needed to express the breast milk from the breasts and then feed the newborn with a bottle.

[0003] Compared to traditional handheld breast pumps, which are relatively inconvenient to use, wearable breast pumps that can be used in conjunction with bras have gradually emerged on the market. Wearable breast pumps are highly integrated and small in size. When in use, they can be placed directly inside the bra. After the user wears the bra, the wearable breast pump can make direct and complete contact with the breast, and the breast pumping operation can be completed without the need for hand or other auxiliary operations, making it extremely convenient and labor-saving to use.

[0004] As shown in the prior art, such as CN 115192800 A, a hands-free wearable breast pump is disclosed, which includes a main unit, a milk storage bottle, a three-way valve, an air bladder, and a duckbill valve. The main unit has an installation cavity with an opening at its front end. The three-way valve has a first end, a second end for installing the air bladder, and a third end for installing the duckbill valve. The air bladder is installed at the second end, the duckbill valve is installed at the third end, and the milk storage bottle is installed on the three-way valve or the main unit. The duckbill valve is connected to the milk storage bottle. The main unit has a push-positioning structure formed in the installation cavity. The three-way valve is detachably installed in the installation cavity and abuts against the push-positioning structure. The three-way valve is pressed against the side wall of the installation cavity by the upward push of the push-positioning structure.

[0005] The aforementioned hands-free wearable breast pump has the advantage of a detachable three-way valve compared to traditional hands-free breast pumps; however, it also has the following drawbacks: (1) In the three-way connector, the airbag chamber used to accommodate the airbag and the nipple chamber used to accommodate the nipple are separate. The three-way connector occupies a large space and has a large overall volume, resulting in a large overall volume of the breast pump and poor comfort when using it. (2) When pouring milk, you need to remove the three-way valve 30 and the milk storage bottle 20 first, and then remove the milk storage bottle 20. That is, you need to disassemble twice to complete the pouring process. The steps are complicated and inconvenient to use. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a wearable, hands-free breast pump to solve the problems of large size in the prior art.

[0007] To achieve the above and other related objectives, this utility model provides a wearable, hands-free breast pump, comprising a detachable main unit and a milk pumping unit; The breast pumping section should include at least: The second shell has a compression chamber and a milk storage chamber. The piston is fitted into the second housing and can separate the compression chamber and the milk storage chamber; The breast shield is detachably fitted with the second housing. The three-way fitting is installed between the breast shield and the second housing and is respectively matched with the piston and the breast shield for limiting. The host portion includes at least: The first housing mates with the second housing; The drive unit is installed inside the first housing; Under the action of the driving component, the piston can contract or return to its original position within the compression chamber.

[0008] In one embodiment of this utility model, the first port of the three-way connector is connected to the breast suction shield, the second port is connected to the piston, and the third port is connected to the milk storage tank.

[0009] In one embodiment of the present invention, the first passage of the three-way member is formed with a conical cover that cooperates with the limiting position of the breast pump.

[0010] In one embodiment of the present invention, the piston is fitted onto one end of the compression chamber near the breast pump, and the second port of the three-way fitting has a limiting step for pressing the piston.

[0011] In one embodiment of this utility model, the third port of the three-way connector forms a first connector, and a milk inlet is provided inside the first connector. Therefore, a one-way valve such as a duckbill valve can be installed at the lower end of the first connector to facilitate unidirectional flow of milk into the milk storage chamber.

[0012] In one embodiment of the present invention, the second housing is provided with a first clearance groove that cooperates with the tee member, and the piston is provided with a second clearance groove that cooperates with the tee member and corresponds to the first clearance groove.

[0013] In one embodiment of this utility model, the inner wall of the piston is provided with a protruding structure.

[0014] In one embodiment of this utility model, the main unit further includes a solenoid valve and a flexible three-way pipe. The solenoid valve is installed inside the first housing. The first port of the flexible three-way pipe is connected to the driving component, the second port is connected to the solenoid valve, and the third port is connected to the compression chamber. Thus, under the action of the driving component, the compression chamber can be made into a negative pressure state, thereby achieving the purpose of milk suction. The solenoid valve can regulate the flow rate and suction force, and the flexible three-way pipe serves as a connection.

[0015] In one embodiment of the present invention, the milk suction part further includes a second connector, which is installed in the second housing. The third port of the soft three-way tube is formed with a third connector that cooperates with the second connector. The second connector has a suction channel that communicates with the compression chamber. In one embodiment of this utility model, an annular groove is provided on one end face of the breast pump near the three-way connector, and a skirt is formed on the second housing to limit and cooperate with the annular groove. The skirt of the second housing is inserted into the annular groove of the breast pump to form a sealing structure. A first opening is provided on the top of the breast pump, and a second opening is provided on the top of the second housing to cooperate with the first opening. The first opening and the second opening together form a complete milk discharge hole / vent hole.

[0016] As described above, the wearable, hands-free breast pump of this invention has the following beneficial effects: 1. This utility model provides a novel wearable, hands-free breast pump with a new structure. The breast pump includes a detachable main unit and a milk-suction unit. The milk-suction unit is a washable component, while the main unit is a non-washable component. The whole is divided into washable and non-washable parts, which not only makes it easy for users to distinguish between them, but also makes it convenient to use and clean. Moreover, the washable part can be disassembled to directly pour out the collected milk, which has the advantages of convenient and efficient milk pouring.

[0017] 2. The wearable, hands-free breast pump of this utility model uses a special, detachable piston that can be matched with a three-way connector. This piston can not only be used as an airbag, but also be matched with the three-way connector to form a nipple compartment that can accommodate the nipple. That is, the piston integrates the piston compartment and the nipple compartment into one unit, reducing the number of components, greatly simplifying the structure, and reducing the volume. This provides more installation space for installing other components. The thickness of breast pumps on the market is generally 60-80cm, while the thickness of the breast pump of this utility model can be as low as about 50cm, which greatly improves the wearing effect and the comfort of use. 3. The four parts that make up the milk pumping part—the breast shield, the three-way connector, the piston, and the second housing—are all detachable. The second housing is also detachable from the main body, which has the advantages of easy disassembly and cleaning. 4. The inner wall of the piston has a raised structure. During the piston's contraction and return, the raised structure can provide contact massage to the user's nipples, which not only ensures a smoother milk pumping process but also provides a massage and health care effect. The structure is simple but highly functional.

[0018] In summary, the main unit and milk-suctioning part of this wearable, hands-free breast pump are detachable, making it convenient to use and pour milk. The second shell, piston, milk-suction cover, and three-way connector that make up the milk-suctioning part are also detachable, making cleaning convenient and thorough. More importantly, it is small in size, thin, and highly comfortable to wear. Attached Figure Description
