Description
Technical field
The present invention relates to a kind of electric breast pump, belong to mother and baby's appliance field.
Background technology
Electric breast pump has mainly been used the phantom that the baby sucks breast milk, utilizes the application of sub-atmospheric pressure in human body (women) breast, and by the variation of air pressure, i.e. the circulation change of " negative pressure "-" normal pressure " is imitated the action of baby's's " inhales puts " sucking breast milk.On the prior art structure, the reciprocating motion principle of selection " piston or barrier film-cylinder " and structure are as the entity of phantom usually.Its operation principle is: do reciprocating by mechanical transmission mechanism driven plunger assembly or barrier film by micro machine in cylinder and pump seat, make the gas in the cylinder realize negative pressure or recover normal pressure.In order to prevent in the pump seat that gas contacts with milk and produces pollution, some electric breast pump is provided with gas-liquid separator between negative pressure pump and three-way suction device.
Find in practice, its weak point of this type of technical pattern is: in reciprocating, to utilize piston or barrier film to move around, be converted into and suck and the action of release, the dynamics of recovering normal pressure during release is inadequate, especially after being provided with gas-liquid separator between negative pressure pump and the three-way suction device, this problem is more outstanding.In addition, because the effect of inertia, the negative pressure pump ratio of reciprocating motion type is easier to produce mechanical wear.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of breast pump with the gas circuit commutator structure is provided.Compare with the prior art breast pump, the dynamics with recovery normal pressure when discharging is large, negative pressure pump is not easy the advantages such as wearing and tearing.
For achieving the above object, technical scheme of the present invention is: described breast pump with the gas circuit commutator structure comprises negative pressure pump, breast cup, three-way suction device and storage feeding bottle; Distinguishedly be: between negative pressure pump and three-way suction device, also be provided with the gas circuit transducer.
The port of described gas circuit transducer includes air-flow output/input port, air-flow output port, air-flow input port, transducer air inlet, transducer gas vent; Be provided with valve block, lower disc in the cavity of described gas circuit transducer; The displacement of described upper valve block and lower disc is subjected to electronic circuit control.
In suction condition, upper valve block and lower disc move up, the transducer inlet close, and the transducer gas vent is opened; In deflated state, upper valve block and lower disc move down, the transducer air inlet open, and the transducer gas vent is closed.
Described negative pressure pump can adopt miniature diaphragm formula vacuum pump, orbiting vane vacuum pump or pendulum piston type vacuum pump.
Also be provided with gas-liquid separator between described gas circuit transducer and the three-way suction device, be provided with isolation cover in the described gas-liquid separator.
When suction condition, upper valve block and lower disc are subjected to electronic circuit control, to top offset, and the transducer air inlet closure, open the transducer gas outlet.Negative pressure pump work, air-flow will enter along the trachea between gas circuit transducer and the gas-liquid separator port of gas circuit transducer, flow through the cavity of gas circuit transducer, enter pump steam inlet along trachea again, the efflux pump gas outlet, enter the gas circuit transducer along trachea, outside transducer gas outlet discharge machine, form a negative pressure loop.Affected by negative pressure, the jack-up that makes progress of the isolation cover in the gas-liquid separator makes breast cup form negative pressure, thereby finishes sucking action.
When deflated state, upper valve block and lower disc are subjected to electronic circuit control, to bottom offset, and the transducer air inlet open, the transducer gas outlet is closed.Negative pressure pump works on, the outer air-flow of machine will enter from gas circuit transducer air inlet the cavity of gas circuit transducer, enter pump steam inlet along trachea again, the efflux pump gas outlet, enter the gas circuit transducer along trachea, by the port of transducer, enter in the gas-liquid separator along the trachea between gas circuit transducer and the gas-liquid separator, form a positive air pressure loop.Affected by positive air pressure, the isolation cover in the gas-liquid separator makes breast cup form malleation, thereby finishes release movement to bottom offset.
More than analyze and can find out: when 1, negative pressure pump was worked, airflow direction always entered from pump steam inlet, flowed out from pumping QI KOU.The negative pressure pump ratio that has overcome reciprocating motion type is easier to produce the defective of mechanical wear; 2, no matter be that a port of gas circuit transducer always communicates with the machine external space when forming negative-pressure air-flow or malleation air-flow, thus suck and the action dynamics of release larger; Although 3 negative-pressure air-flows or malleation air-flow communicate with the outer atmosphere of machine, owing to be provided with gas-liquid separator between gas circuit transducer and three-way suction device, air-flow and breast milk are thoroughly isolated, and have guaranteed that breast milk is not subjected to the pollution of air.
