MUFFLING AIR PUMP STRUCTURE FOR BREAST PUMP

WIPO Patent Application WO/2024/074058

A1

A muffling air pump structure for a breast pump. A bracket is hermetically mounted on a machine housing with an opening at one end. A motor is mounted on the outer side of the bracket. A rotating shaft of the motor is a lead screw that passes through the bracket, extends into the machine housing, and is connected to a piston by means of a lead screw nut. A muffling air channel that communicates with the inner side and the outer side and can muffle a sound is further arranged on the bracket. The muffling air channel comprises a plurality of muffling cavities connected in sequence. Each of the muffling cavities is provided with a muffling hole. Some of the muffling cavities are provided with muffling plates, which further divide the muffling cavities into large and small cavities, thereby creating a multi-stage muffling structure that greatly muffles noises. The arrangement of the muffling air pump structure for a breast pump can greatly reduce the noise generated by the operation of the breast pump, thereby preventing the use of the breast pump from affecting the environment where the breast pump is used too much, creating a restful environment for a newborn and the newborn's mother, and making the breast pump more comfortable to use.
