Description
Technical field
This utility model relates to a kind of negative pressure device for breast pump, belongs to mother and baby's appliance field.
Background technology
Negative pressure device is widely used at medical instruments field, has its figure in the medical apparatus and instruments that a lot of negative pressure is drawn, and breast pump is exactly wherein a kind of.At present, the negative pressure device in breast pump is distinguished from structure, mainly contains diaphragm type and piston type two kinds.Relative to diaphragm type negative pressure device, the shortcoming of piston type negative pressure device is that volume is comparatively large, power consumption is larger.But puerpera's use occasion is generally that volume does not hinder greatly a little louder at home.Though power consumption is large, just more than diaphragm type several watts, still belong to low power range.And its advantage is outstanding: 1, piston movement one_to_one corresponding synchronous with milking action, in direct periodically corresponding relation; 2, rhythm is obvious, action nature, the curved ripple of change of elicitation process suction, smooth gradual change; 3, suction size and speed speed can independent regulation and there is not mutual restricting relation, and can form the multiple assembled scheme of gear product, thus emulator is higher; 4, high strength can be selected to suck scheme according to the adapt of user, break through the routine normally sucking and alleviate long-pending milk distending pain, realize neonate mother lactogenesis and open milk.Thus deeply like by user, still widely use in the breast pump of higher gears.
Therefore, producer never stops the technological improvement of piston type negative pressure device, domesticly discloses the reciprocal aspirator of a kind of Compact structural, is characterized in reducing half volume than same level prior art, achieves portable object.But its weak point is: under the condition of volume defining, the power that sucks of single cylinder is smaller.Owing to adopting rubber mass synchronous cog belt, fault rate is higher, and service life is shorter.In addition, owing to adopting single cylinder
,piston adopts stroke longer, works easily stuck, less stable.
withprior art is compared, and this patent does not have new breakthrough.
Summary of the invention
The main technical problems to be solved in the utility model is, a kind of negative pressure device for breast pump is provided, with compared with prior art, in the concordance of this negative pressure device suction size and speed speed when sucking high-power use, bilateral use, complete machine stability and service life etc., there is new breakthrough.
This utility model patent is achieved through the following technical solutions: the negative pressure device of a kind of breast pump described in the utility model, comprise: for generation of two piston type negative pressure pumps of negative pressure, for providing the motor rotating original moment, for the rotation of described motor being exported the gear transmission unit carrying out slowing down and commutating; Distinguished, this negative pressure device is also provided with driving crank, and the piston combination of two negative pressure pumps is connected with connecting rod respectively with between driving crank; One end of driving crank is connected with gear transmission unit.
Described connecting rod is by the fastening of connecting rod snap close at bent axle, and piston combination is fixed by bearing pin and snap ring and connecting rod.
Described piston combination comprises piston casting die, piston overlapping piece, T-shaped of piston and two U-shaped piston rings.
Described two U-shaped piston rings are nested on piston overlapping piece, T-shaped of piston respectively.
A kind of negative pressure device for breast pump of the present utility model, owing to adopting twin shaft cylinder, compared with the single-acting cylinder of same volume, twin shaft cylinder piston stroke is shorter, and not easily stuck during work, stability is high.Human breast sensitivity is comparatively strong, more responsive to the perception of suction power, when breast pump carries out bilateral suction breast to human breast, require that bilateral suction size and speed speed should be consistent as far as possible, and suction size and speed should in suitable scope.Of the present utility model pair of cylinder owing to adopting same crank-driven, the concordance of the two cylinder actions that ensure that.Complete machine does not adopt rubber driving member, and fault rate is lower, and service life is longer.
