Description

A kind of breast pump with the gas circuit commutator structure
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 through 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: in cylinder and pump seat, do reciprocating through mechanical transmission mechanism driven plunger assembly or barrier film by micro machine, 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 threeway extractor.
Find in practice; Its weak point of this type of technical pattern is: in reciprocating; Be to utilize piston or barrier film to move around, be converted into and suck and the action of release that it is not enough to recover non-pressurized dynamics during release; Especially after being provided with gas-liquid separator between negative pressure pump and the threeway extractor, this problem is more outstanding.In addition, because action of inertia, the negative pressure pump of reciprocating motion type relatively is easy to generate mechanical wear.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of breast pump with the gas circuit commutator structure is provided.Compare with the prior art breast pump, have and recover when discharging that non-pressurized dynamics is big, negative pressure pump is not easy advantages such as wearing and tearing.
For realizing above-mentioned purpose, technical scheme of the present invention is: the breast pump of said band gas circuit commutator structure comprises negative pressure pump, breast cup, threeway extractor and storage feeding bottle; Distinguishedly be: between negative pressure pump and threeway extractor, also be provided with the gas circuit transducer.
The port of said 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 said gas circuit transducer; Said displacement of going up valve block and lower disc receives electronic circuit control.
In suction condition, last valve block and lower disc move up, the transducer inlet close, and the transducer gas vent is opened; In deflated state, last valve block and lower disc move down, the transducer air inlet open, and the transducer gas vent is closed.
Said 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 said gas circuit transducer and the threeway extractor, be provided with isolation cover in the said gas-liquid separator.
When suction condition, last valve block and lower disc receive electronic circuit control, to top offset, and the transducer air inlet closure, open the transducer gas outlet.Negative pressure pump work; Air-flow will get into the port of gas circuit transducer along the trachea between gas circuit transducer and the gas-liquid separator, flows through the cavity of gas circuit transducer, gets into pump steam inlet along trachea again; The efflux pump gas outlet; Get into the gas circuit transducer along trachea, outside transducer gas outlet discharge machine, form a negative pressure loop.Influenced 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 accomplishes sucking action.
When deflated state, last valve block and lower disc receive 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 get into the cavity of gas circuit transducer from gas circuit transducer air inlet, gets into pump steam inlet, efflux pump gas outlet along trachea again; Get into the gas circuit transducer along trachea; Through the port of transducer, get in the gas-liquid separator along the trachea between gas circuit transducer and the gas-liquid separator, form a positive air pressure loop.Influenced by positive air pressure, the isolation cover in the gas-liquid separator makes breast cup form malleation to bottom offset, thereby accomplishes releasing action.
More than analyze and can find out: when 1, negative pressure pump was worked, airflow direction always got into from pump steam inlet, flowed out from pumping QI KOU.The negative pressure pump that has overcome reciprocating motion type relatively is easy to generate 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 bigger; Though the outer atmosphere of 3 negative-pressure air-flows or malleation air-flow and machine, owing between gas circuit transducer and threeway extractor, be provided with gas-liquid separator, air-flow and breast milk are thoroughly isolated, and have guaranteed that breast milk does not receive the pollution of air.
