Description

Technical Field

[0001] The utility model patent relates to the technical field of maternal and infant products, and specifically to a milk suction component of a breast pump. Background Art

[0002] In the prior art, electric breast pumps can be divided into two types according to the form of milk extraction: integrated wearable type and split type. Among them, integrated wearable breast pumps generally do not have a catheter, and the main unit is directly connected to the milk extraction part; split breast pumps generally connect the main unit and the milk extraction part through a catheter to achieve negative pressure transmission.

[0003] The disadvantages of the prior art are that the breast pumping components of the integrated wearable and split electric breast pumps are generally not interchangeable. For working women, they generally use split electric breast pumps at home and often use integrated wearable electric breast pumps at work. If the negative pressure hole of the breast pumping component of the existing wearable breast pump is directly connected with a catheter, the connection part is not easy to meet the airtightness requirements and is prone to air leakage. This greatly limits the use of the breast pump.

[0004] Chinese utility model patent CN 220344836U discloses a breast pump cup assembly for a wearable breast pump. However, the breast pump cup assembly can only be directly connected to a host, and is limited to being used in a wearable state, and cannot be converted into a split breast pump. Utility Model Content

[0005] The purpose of the utility model is to provide a wearable breast pumping assembly for breast pumping. Compared with the prior art, the breast pumping assembly can not only be directly combined with a host to form a wearable breast pump, but also can be converted and combined to form a split breast pump. It is suitable for use in different occasions. The connection part can easily meet the airtightness requirements and will not leak. It has the advantages of simple structure, easy operation, high performance and low cost.

[0006] In order to achieve the above invention objectives, the technical solution adopted by the present utility model is as follows.

[0007] Technical solution 1:

[0008] A breast pump assembly of a wearable breast pump comprises: a breast shield for sucking milk, a diaphragm for gas-liquid separation, and a milk bowl for collecting milk. Furthermore, a cover plate is provided at the top end of the breast pump assembly, a negative pressure channel is provided in the central area of ​​the cover plate, and the lower end concave hole of the cover plate negative pressure channel is embedded in the negative pressure port of the top end of the breast pump assembly; the upper end concave hole of the cover plate negative pressure channel is used to embed the cover plate plug of the negative pressure gas circuit external connection joint.

[0009] The negative pressure pipe embedded joint at the other end of the negative pressure gas circuit external connection joint is connected to one end of the catheter, and the other end of the catheter is connected to the main machine.

[0010] A plug gas circuit is arranged in the negative pressure gas circuit external connection joint.

[0011] In the wearable state, the top end of the breast pump component is separated from the cover plate, and the main unit for providing negative pressure is directly sleeved on the negative pressure port at the top end of the breast pump component.

[0012] Technical solution 2:

[0013] A breast pumping assembly of a wearable breast pump comprises: a breast pumping shield for sucking milk, a diaphragm for separating gas and liquid and preventing milk from flowing back into a main machine; a milk bowl for collecting milk, a three-way structural member installed inside the milk bowl, and a one-way valve installed at the milk outlet of the three-way structural member; the three-way structural member is provided with a closed and mutually connected milk suction port, a milk outlet and a negative pressure port; the breast pumping shield is trumpet-shaped, one end of which is in close contact with a human breast, and the edge is provided with a mounting groove, which can buckle the milk bowl, and the other end is installed to the milk suction port of the three-way structural member; the top of the milk bowl is provided with a negative pressure port, and the diaphragm is installed on the negative pressure port of the three-way structural member.

[0014] Furthermore, a milk bowl cover is provided at the top end of the milk bowl, and a negative pressure channel is provided in the central area of ​​the milk bowl cover, and the lower end concave hole of the negative pressure channel of the milk bowl cover is embedded in the milk bowl negative pressure port at the upper end of the milk bowl; the upper end concave hole of the negative pressure channel of the milk bowl cover is used to embed the milk bowl plug of the negative pressure air circuit external connection joint.
