Breast Pump Driving Apparatus

Abstract

A breast pump driving apparatus is provided. A stepper motor is provided at a housing having an open end through a bracket; an output shaft of the stepper motor is a screw and connected to a piston through a screw nut; the other end of the housing is provided with an air tube joint and a one-way valve to cooperate with an inner cavity of the housing to generate different air pressures; and the bracket is provided with a muffling airway for reducing working noise. The breast pump driving apparatus changes the air pressure by driving the piston to move through the stepper motor and the screw-nut pair, achieving precise action and stable suction, and avoiding flow attenuation, thereby ensuring accurate suction and improving user comfort. The breast pump driving apparatus has good working stability and low requirements for airtightness, reduces the failure rate, and improves the convenience of use.
