Description
Technical field
The invention belongs to one utilizes air pressure to help puerpera's milk let-off gear(stand), specifically, is a kind of breast pump with gas channels dehydrating unit.
Background technology
In prior art, milk sucking device, be generally made up of negative pressure pump, three-way component and storage feeding bottle, wherein, one end of three-way component is communicated with negative pressure pump by negative tube, to form negative pressure wherein; The other end connects or is fixed with the cup of an enlarging gradually; Meanwhile, then one end is connected with storage feeding bottle, and the milk imported by negative pressure is collected through storage feeding bottle.
The milk just secreted due to human body has certain temperature, and general higher than room temperature, so the humidity in three-way component is comparatively large, easily makes the fog in milk take in flexible pipe and forms condensation, and along with negative pressure extraction, can enter negative pressure pump through pipeline.Because negative pressure pump inside cannot be cleaned, after life-time service, negative pressure pump can become the hotbed of bacteria breed, causes the clump count of negative pressure pump far above environment for use, and the gas of high humility also can have influence on breast pump overall performance.
US Patent No. 6921379 discloses a kind of breast pump, is provided with membrane structure in three-way component, the vacuum chamber of air pump and the air chamber of humalacter is kept apart, and by the negative pressure in the vacuum chamber of electromagnetic valve release air pump.This structure can make the suction function of negative pressure pump on thin film, change the change of humalacter air pressure, avoids the negative pressure of negative pressure pump to contact with milk, and prevents milk volatilization steam from entering in negative pressure pump.But this structure exists following problem: the negative pressure of humalacter is less than the negative pressure of negative pressure pump, reduce the maximum suction of breast pump; On the other hand, thin film needs stretch-draw repeatedly to shrink, and easy loss is damaged, needs regular replacing.
Except above-described thin film isolation structure, prior art air pump also adopts gasbag isolation structure.Namely between vacuum chamber and the air chamber of humalacter, be provided with concave shape pneumatophore or the bowl-type diaphragm with soft flexible material is made, any aperture is not stayed in wall portion and bottom.The pressure of gas realizes the transmission of pressure by the distortion of pneumatophore or bowl-type diaphragm.Although this kind of structure achieves isolation between vacuum chamber and the air chamber of humalacter completely, but in actual applications, there is following problem: 1, pneumatophore or bowl-type diaphragm often can not restore to the original state from deformation state very soon when normal pressure, cause milk can not flow in storage feeding bottle in time; 2, because pneumatophore or bowl-type diaphragm can reduce the intensity of negative pressure in the transmittance process of pressure, therefore this kind of structure is obviously not suitable for needing sucking the larger occasion of intensity level.
Summary of the invention
The object of the invention is to overcome prior art deficiency and a kind of breast pump with gas channels dehydrating unit is provided, this breast pump can utilize gas channels dehydrating unit, isolate steam in gas, stop steam to enter negative pressure pump, reach the object preventing negative pressure pump breed bacteria and protection breast pump; This breast pump is also applicable to needs and sucks the larger occasion of intensity level very much.
Breast pump of the present invention is realized by following scheme: a kind of breast pump with gas channels dehydrating unit, comprises the coniform breast cup contacted with human breast, carries out with described humalacter, feeding bottle and negative pressure input channel the threeway parts that are connected; Distinguished, in threeway parts, be also provided with a gas channels dehydrating unit; Two gas circuit ports of described gas channels dehydrating unit are connected with three-way component with negative pressure pump respectively; Described gas channels dehydrating unit inner chamber is provided with tortuous roundabout gas channels.
In such scheme, described gas channels dehydrating unit is made up of disengagement chamber top and disengagement chamber bottom; Described disengagement chamber top and disengagement chamber bottom closely fasten, and form disengagement chamber.
In such scheme, in described disengagement chamber bottom, be provided with several contour barrier boards erectting arrangement; The bottom of barrier board is connected with the inner surface of side with disengagement chamber bottom, and the opposite side of barrier board and the inner surface of disengagement chamber bottom leave gas circuit path; The bottom surface on disengagement chamber top is adjacent to the top of barrier board; Barrier board forms tortuous roundabout gas channels in disengagement chamber by splitting.
In such scheme, the gas channels that the barrier board in described disengagement chamber is formed also is erect and is provided with several baffle plates; Space is left between described baffle plate and barrier board passage.
In such scheme, after disengagement chamber top and disengagement chamber bottom are adjacent to, between the barrier board of described baffle plate and disengagement chamber bottom, leave vapour grid space; Described vapour grid space can be U-shaped or inverted U.
In such scheme, the barrier board surface of described disengagement chamber bottom can be rough rough surface.
Another kind of embodiment.The gas channels arranged in described gas channels dehydrating unit also can be made screw type; Two gas circuit ports are separately positioned on the end at the whole story of spiral gas channels.
Two the gas circuit port levels height arranged have certain drop, and the gas circuit port be wherein connected with negative pressure pump is in eminence, and the gas circuit port be connected with the gas circuit in three-way component is in lower.
We are found by a large amount of experiments, this breast pump by loading onto gas channels dehydrating unit below top cover, when fog enters gas channels dehydrating unit, by the gas channels that the complications of the inner unique design of disengagement chamber are roundabout, the effect stopping fog effectively can be played.Namely when there being fog to enter disengagement chamber, disengagement chamber is because being designed with the roundabout gas channels of longer complications, first such fog first solidify on the surface of the barrier board of disengagement chamber inside and baffle plate and form the globule afterwards, stay in disengagement chamber, effectively block fog directly to enter main frame and affect performance, play the effect realizing gas-liquid isolation.Especially use in season in winter, ambient temperature is than in the larger situation of the temperature difference of sucking-off milk, and this breast pump with gas channels dehydrating unit more has obvious action effect.Owing to not having the isolation of pneumatophore or bowl-type diaphragm, this breast pump is also applicable to needs and sucks the larger occasion of intensity level very much.
