Abstract
The invention relates to the field of mother and baby products, in particular to a breast pump. A mechanical self-pressure-stabilizing breast pump comprises a breast pump body. A negative pressure assembly is arranged in the breast pump body and comprises a negative pressure cavity. A sucking opening of the negative pressure cavity is communicated with a breast pumping portion, an air exhausting opening of the negative pressure cavity is communicated with a storage portion, an inflating opening is further formed in the negative pressure cavity, a sealing cover is arranged in the negative pressure cavity, an elastic pre-tightening component is arranged between the sealing cover and the inner wall of the negative pressure cavity, and the elastic pre-tightening component can provide tension to enable the sealing cover to cover the inflating opening. Due to the fact that the elastically-controlled sealing cover can seal the inflating opening, the external pressure can overcome elastic force to push the sealing cover open when the pressure of the negative pressure cavity is smaller than a set value. The sucking force can be freely adjusted by changing the elastic force of the tension spring to enable different users to achieve the most suitable sucking force, so that the body health can be guaranteed, and the breast pumping effect is also improved.
Description
Technical field
The present invention relates to mother and baby's articles for use field, relate in particular to a kind of breast pump.
Background technology
Breast pump is a kind of mother and baby's articles for use for sucking-off breast milk.When baby cannot directly suck breast milk, can be by breast pump by breast milk sucking-off, to guarantee the nursing of breast milk.Breast pump is divided into electronic and manual two kinds of forms.Wherein, existing electronic breast pump aspirates because of the negative pressure of using air pump or motor to produce, suction force indirectly acts on breast, so the voltage stabilizing that is difficult to suction force to carry out is accurately and fast controlled, when suction force is excessive, may cause breast soft tissue to pull, and the effect that suction force hour sucks is bad; The toleration of different people is different, considers safety factors, can only adopt the suction force of lower standard to guarantee safety, can not guarantee the effect that sucks by increasing suction force, and therefore existing this class electric breast pump practical effect is unsatisfactory.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of machinery from voltage stabilizing breast pump, on the vacuum cavity of this breast pump, be provided with an inflation inlet, when the pressure of vacuum cavity is during lower than setting value, external atmosphere pressure will overcome elastic force seal cover is pushed open, guaranteed the stable of suction force, can guarantee healthyly, can improve the effect sucking again.
The present invention is achieved in that a kind of machinery is from voltage stabilizing breast pump, comprise breast pump body, in breast pump body, be provided with negative pressure assembly, described negative pressure assembly comprises a vacuum cavity, the pump orifice of described vacuum cavity is connected with the portion of sucking, in the air vent of vacuum cavity, be provided with check valve, on described vacuum cavity, be also provided with inflation inlet, in institute's vacuum cavity, be provided with seal cover, between seal cover and vacuum cavity inwall, be provided with elasticity pretension parts, elasticity pretension parts provide pulling force that seal cap sealing is covered on inflation inlet.
Described elasticity pretension parts are extension spring.
Between described seal cover and vacuum cavity inwall, be also provided with rubber seal, described rubber seal is fixedly installed on seal cover.
Described breast pump body comprises motor, kinematic link assembly, negative pressure barrier film and threeway, described motor drives negative pressure diaphragm movement to make vacuum cavity produce negative pressure by kinematic link assembly, and three interfaces of described threeway are communicated with respectively pump orifice, the liquid outlet of the portion that sucks, the inlet of reservoir of vacuum cavity.
Described reservoir is detachably arranged on breast pump body.
Machinery of the present invention is provided with an inflation inlet from voltage stabilizing breast pump, the seal cover of controlling by elasticity seals inflation inlet, when the pressure of vacuum cavity is during lower than setting value, external atmosphere pressure will overcome elastic force seal cover is pushed open, guaranteed the stable of suction force, the size of required suction force can, by changing the elastic force free adjustment of tension spring, make different users can obtain an optimal suction force, can guarantee healthyly, can improve the effect sucking again.
Accompanying drawing explanation
Fig. 1 is that machinery of the present invention is from the structural scheme of mechanism of voltage stabilizing breast pump;
Fig. 2 is the partial enlarged drawing in negative pressure assembly inflation inlet region in the present invention.
In figure: 1 breast pump body, 2 negative pressure assemblies, 3 suck portion, 4 reservoir, 11 motors, 12 kinematic link assemblies, 13 negative pressure barrier films, 14 threeways, 21 pump orifices, 22 air vents, 23 inflation inlets, 24 vacuum cavities, 25 seal covers, 26 elasticity pretension parts, 27 rubber seal.
