[0004] As an important part of modern lactation support equipment, the breast pump provides great convenience for mothers who cannot directly breastfeed. A complete breast pump system usually includes a host, a milk storage container, and other auxiliary components. Among them, the milk storage container is the part that directly contacts the mother's breast and is responsible for collecting milk and guiding it into the milk storage container. Therefore, the sanitary condition of the milk storage container is crucial to ensure the quality of the milk and the health of the baby. However, in actual use, the traditional breast pump has some significant problems: easy breeding of bacteria: due to frequent use and direct contact with human skin, if not properly cleaned or disinfected, the milk storage container can easily become a good environment for bacterial growth. Unhygienic and unsafe: once the milk storage container is contaminated, not only the quality of the milk is affected, but also pathogenic organisms can be transmitted to the baby, threatening their health. Limitations of traditional disinfection methods: many users use the water boiling method to disinfect the milk bowl assembly. Although this method is simple and effective, long-term high-temperature treatment can cause the plastic material to deform or even release harmful substances, and also shorten the service life of the product.
