[0004] As an important device for assisting breastfeeding, breast pumps are widely used in modern families and medical institutions, especially for working mothers and infants with special care needs, their convenience and practicality have been recognized by the majority of users.

[0005] Although the existing design of breast pumps is quite mature, there are still some technical problems to be solved in actual application. In particular, it is worth noting that some breast pumps may have milk backflow to the host during operation. This backflow problem not only may cause internal pollution of the host, increase the difficulty of cleaning and maintenance, and shorten the service life of the equipment, but also may cause health and safety hazards, affect breast milk quality and infant health. The reasons for backflow are various, which may be due to insufficient sealing performance of the connection part between the host and the milk storage container, or may be due to negative pressure fluctuation or sudden interruption during breast pumping, causing milk to flow in reverse.

[0006] The existing design of breast pumps usually focuses on optimizing the efficiency of negative pressure generation and the comfort of breast pumping, while the special protection measures to prevent milk backflow to the host are relatively lacking. Common connection structures, such as simple buckles, screwing or plug-in interfaces, are easy to assemble and disassemble, but may have limitations in dealing with the sealing challenge under negative pressure environment. In addition, some breast pumps on the market have tried to use various sealing elements or improved connection methods to reduce the risk of backflow, but in actual use, especially in the case of improper user operation, equipment aging or untimely maintenance, it is still difficult to completely avoid the occurrence of backflow phenomenon.
