Abstract:
The present patent relates to the field of breast pumps, and in particular to an integrated breast pump, comprising a cup cover and a horn cover embedded in the cup cover. The cup cover and the horn cover define a milk storage cavity, a milk suction channel for allowing a nipple to enter is formed in the horn cover, a milk outlet mechanism communicated with the milk storage cavity is formed in the side surface of the milk suction channel, the milk outlet mechanism controls milk to enter the milk storage cavity, an air cylinder is fixed to the bottom of the milk suction channel, the air cylinder covers the inner side surface of the cup cover, and a ventilation hole corresponding to the position of the air cylinder is formed in the cup cover. The horn cover is sealed by using the air cylinder in addition to a bottom seal of the horn cover, thereby reducing an unnecessary structure; the air cylinder is built in, thereby reducing the number of parts while ensuring the sealing performance of the horn cover; moreover, the air cylinder, serving as the bottom seal of the horn cover, can control the air pressure in the horn cover more directly, such that an external air pump achieves a better milk suction effect under the same power, the energy utilization rate is increased, and more energy is saved.
