FIELD: medical equipment.SUBSTANCE: invention relates to medical devices. Electric aspirator comprises electric motor, pump, suction cap, release device for breast milk, connected with connection channel to suction cap, which is connected to release device of reservoir for breast milk collection. Discharge valve is located in release device, which is closed, if pressure difference in reservoir and suction cap reaches certain minimum value, and opens, if minimum value is not reached. Float valve chamber bottom is connected to connection channel, and at top it has through hole and sealing surface, surrounding through hole. In float valve chamber float if located, which comprises seal on top, which is tightly adjoined to sealing surface, if float pops up in float valve chamber. Suction line connects through hole with pump inlet. First three-way valve with electric control is placed in suction line. Pressure line connects connection channel with pump outlet. Second three-way valve with electric control is placed in pressure line. Electronic control system is electrically connected with devices for electric motor switching on and off, control of electric motor and first and second three-way valves, and it is made with possibility to actuate electric motor in working state, providing operation of electric motor and first and second three-way valves in form of cycles, or rest state, depending on state of devices for electric motor switching on and off. Cycles include suction phase, during which electric motor is switched on, pump inlet through suction line and first three-way valve is connected to through hole and pump outlet through pressure line and second three-way valve is connected to environment, and which also contain pressurization phase, during which electric motor is switched on, pump inlet through suction line and first three-way valve is connected to environment, and pump outlet through pressure line and second three-way valve is connected to connection channel
