Description

Breast pump

Technical Field

The utility model relates to the field of mother and infant products, in particular to a breast pump.

Background

Breast feeding is very common, but infants are easy to hurt female breasts by sucking milk directly by the mouth, and when the infants are fed by females, the residual breast milk in the female breasts after the infants are full can increase risks of blocking breasts, rising milk, mastitis and the like. Breast pumps can help women to express breast milk before feeding or storing it directly. After the breast pump is used, the breast pump needs to be cleaned and stored for the next use, and if the breast pump is not cleaned in time, germs are easy to breed.

At present, the breast pump assembly in the market is numerous, and the breast pump assembly can be completely disassembled for cleaning, so that the breast pump is quite inconvenient. The air exchange valve of the existing breast pump is a part which needs to be disassembled singly for cleaning, has smaller volume and is easy to lose in the cleaning or storage process. In addition, the independently arranged scavenging valve is not easy to install in place during installation, is easy to incline, and leads to the reduction of the suction force of the breast pump, thereby influencing the working efficiency.
