Abstract
The invention relates to a negative pressure generator of a breast pump. The negative pressure generator comprises a support, a leather cup and a pull rod. The support is fixed on a tee joint component. The negative pressure generator is characterized by further comprising a crankshaft and a rocker, wherein a rotary handle is arranged at the other end of the rocker. The rotary handle drives the rocker to rotate circumferentially to drive the pull rod and the leather cup to move up and down, and the leather cup reciprocates through rotation of the rocker to generate negative pressure. The problems that manual breast pumps are low in pumping speed, labor consuming and the like are solved effectively. According to another technical scheme, a motor is substituted for a hand-cranking device in the first technical scheme; compared with existing electric breast pumps, the second technical scheme has the advantages of simple structure, low price and the like.
Description
Technical field
The present invention relates to a kind of mother and baby's articles for use field, more particularly, the present invention relates to a kind of breast pump.
Background technology
Breast pump as a kind of mother and baby's articles for use, generally by a laminating female breast humalacter, one for collecting the feeding bottle of milk, the three-port structure of negative pressure generating device and this three of connection forms.
At present, the negative pressure of hand-operated breast pump produces structure and mainly contains three kinds of forms: pressing type, syringe hand drawing type and ball pump type.These three kinds of negative pressure produce each defectiveness of structure: press breast pump suction is little; Syringe hand drawing type breast pump volume is large, and aspiration procedure can produce a kind of sensation of clashing into breast; Ball pump type breast pump uses effort.And these three kinds of negative pressure produce structure all by common shortcoming---the speed that sucks is slower.
Analyze further, the negative pressure of existing automatic breast pump produces structure, and be generally all provided with the control circuits such as CPU, complicated structure, price is also higher.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of negative pressure generating device of breast pump is provided.Compared with the hand-operated breast pump of prior art, this negative pressure generating device can efficiently solve hand-operated breast pump and to suck the problems such as speed is slow, effort; Further, another technical scheme of this negative pressure generating device, compared with the electric breast pump of prior art, also has the advantages such as structure is simple, low price.
The object of the invention is to be achieved through the following technical solutions: a kind of negative pressure generating device of breast pump, comprises support, leather cup, pull bar, and described support is fixed on threeway parts; Distinguished: this negative pressure generating device also comprises bent axle, rocking bar; Described crankshaft installed is on support; Through hole is arranged at the bottom of described leather cup, and extends inward out a shoulder; Described pull bar is through the through hole of leather cup, and tension leather cup, is buckled on bent axle; One end of bent axle and one end of rocking bar are fixed together; The other end of rocking bar is provided with and revolves handle; By revolving driving rocking bar to make circular-rotation, drive pull bar and leather cup to move up and down, by the rotation of described rocking bar, leather cup moves back and forth, and produces negative pressure.
One end of bent axle also can integratedly be formed with the connection of one end of rocking bar.
Certainly, revolve and also can integratedly be formed with the connection of rocking bar.
Another technical scheme of the present invention:
A negative pressure generating device for breast pump, comprises support, leather cup, pull bar, and described support is fixed on threeway parts; It is characterized in that; This negative pressure generating device also comprises bent axle, and described crankshaft installed is on support; Through hole is arranged at the bottom of described leather cup, and extends inward out a shoulder; Described pull bar is through the through hole of leather cup, and tension leather cup, is buckled on bent axle; One end of bent axle is connected with the driving shaft of motor, is rotated by motor driven crankshafts, drives pull bar and leather cup to move up and down, is moved up and down, leather cup is moved back and forth by described pull bar, produce negative pressure.
The negative pressure generating device of a kind of breast pump that the present invention relates to, by above technical scheme, efficiently solves hand-operated breast pump and to suck the problems such as speed is slow, effort.Another technical scheme of the present invention, replaces the manual setter in first technical scheme with motor, than existing electric breast pump, really has the advantages such as structure is simple, low price.
