Abstract

The utility model discloses a manual press breast pump. The breast pump comprises a bottle for accommodating breast milk, and a trumpet-shaped absorption cover, wherein a connecting pipe which is connected to an opening on the upper part of the bottle in a detachable mode is integrally formed at the output end of the absorption cover; a first accommodating cavity communicated with the bottle is formed on the lower part of the connecting pipe; a rubber sleeve is buckled on the upper part of the connecting pipe; a second accommodating cavity communicated with the absorption cover is formed at the periphery of the upper part of the rubber sleeve and the connecting pipe; a one-way valve is arranged between the first accommodating cavity and the second accommodating cavity; a handle is hinged outside the connecting pipe; and one end of the handle is hung on the rubber sleeve. Compared with the conventional manual press breast pump, the manual press breast pump has a simple structure and is high in absorption efficiency, convenient to operate, relatively low in manufacturing cost and convenient to popularize and use.

Description

Manual pressing type breast pump

Technical field

This utility model relates to a kind of Infants'feeding apparatus, is specifically related to a kind of manual pressing type breast pump.

Background technology

Manual pressing type breast pump; Be to be used to extrude the instrument that accumulates in the breast milk in the mammary gland, generally, can't directly suck breast milk or mother directly under the situation of feeding infant the baby; Utilize manual pressing type breast pump with the breast milk sucking-off; Be placed in the feeding bottle, when needing to feed, utilize feeding bottle to feed again.

Existing manual pressing type breast pump mainly is divided into type hand and power type, the power type complex structure, and cost an arm and a leg, be unfavorable for popularizing; The collapsible part of the manual pressing type breast pump of existing type hand adopts rubber pneumatic bag mostly; Utilize the resilience force of rubber pneumatic bag self that the suction that breast produces is extruded breast milk; Yet; The pressure that the rubber pneumatic bag resilience is produced is less, causes the absorption efficiency of this manual pressing type breast pump comparatively low.

The utility model content

To the deficiency of prior art, the purpose of this utility model is intended to provide a kind of manual pressing type breast pump, and it is simple to operate, and has higher absorption efficiency.

For realizing above-mentioned purpose, this utility model adopts following technical scheme:

Manual pressing type breast pump; Comprise and be used to put holding bottle and being trumpet-shaped absorption cover of breast milk; The outfan of said absorption cover is one-body molded to have one to be detachably connected on the connection tube that holds bottle upper opening, said connection tube bottom have one with hold first containing cavity of bottle conducting, the top spiral-lock of said connection tube has a gum cover; The top periphery formation one and second containing cavity that absorbs the cover conducting of said gum cover and connection tube; Be provided with a check valve between said first containing cavity and second containing cavity, the external hinge of connection tube is connected with the leader, and an end of handle is mounted on the gum cover.

Be connected with one on the said gum cover and mount bar, an end of said handle is mounted on said mounting on the bar.

The outer setting of said connection tube has the pivot of a horizontal expansion, and handle pivot is connected on this pivot.

Between first containing cavity and second containing cavity, be provided with a baffle plate in the said connection tube; This baffle plate be provided with one can supply check valve upper end plug-in mounting through hole, on the lower limb of said check valve is positioned at said through hole the peripheral and airtight lower surface that is fitted in baffle plate.

The outside of said absorption cover is also buckled and is provided with a dust cap.

The beneficial effect of this utility model is:

1, than the manual pressing type breast pump of existing type hand, it has higher absorption efficiency;

2, simple in structure, easy to operate, cost of manufacture is relatively low, is convenient to promote the use of.

Description of drawings

Fig. 1 is the structural representation of a kind of manual pressing type breast pump of this utility model;

Fig. 2 is a D place zoomed-in view among Fig. 1;

Fig. 3 is the structural representation of check valve among Fig. 2.

The specific embodiment

Below, in conjunction with the accompanying drawing and the specific embodiment, this utility model done further describing:

Like Fig. 1,2, shown in 3; Be a kind of manual pressing type breast pump of this utility model, it comprises and is used to put holding bottle 1, being trumpet-shaped absorption cover 2 and handle 7 of breast milk, is provided with a connection tube 3 absorbing cover 2 trumpet-shaped rear ends; The bottom of this connection tube 3 is (certain through being threaded with the bottleneck edge that holds bottle 1; Also can be other the mode that removably connects), be provided with a baffle plate 31 in the tube chamber of connection tube 3, the upper opening lid of connection tube 3 is established a gum cover 5; Gum cover 5 surrounds a cavity B with the top of baffle plate 31 and connection tube 3, and this cavity B and 2 conductings of absorption cover; Baffle plate 31 surrounds a cavity A with the bottom of connection tube 3; Be connected with one on the gum cover 5 and mount bar 6; In the outer setting of connection tube 3 a horizontal pivot 8 is arranged, handle 7 is articulated on the pivot 8, and the front end of handle 7 is mounted on the upper end that mounts bar 6; When the rear end of handle 7 along C to when pivot 8 rotates; Its front end will mount upwards pulling of bar 6, and deformation takes place gum cover 5, and the volume of cavity B is increased.A preset through hole 32 on baffle plate 31; One check valve 4 is installed in the through hole 32; The lower limb external diameter of this check valve 4 is greater than the internal diameter of through hole 32, and the airtight lower surface that is fitted in baffle plate 31, and the edge that check valve 4 is inserted in the through hole 32 is provided with a plurality of guiding gutters 41.

During use, the tubaeform outside opening that absorbs cover 2 is enclosed within outside the breast, the above-mentioned C in edge is to pulling handle 7; The volume of cavity B increases, and its internal pressure reduces, and breast milk enters into cavity B by absorbing cover 2; Unclamp handle 7, then gum cover 5 resiliences and return to original shape, cavity B volume reduces; Internal pressure increases, the generation deformation that is under pressure of the lower edge of check valve 4, and break away from the lower edge of baffle plate 31; Breast milk among the cavity B enters into cavity A by the guiding gutter on the check valve 4 41, is collected into then to put in the bottle 1.

In addition, also buckle in the horn opening outside of above-mentioned absorption cover 2 and to be provided with a dust cap 9, under non-working condition, dust cap 9 is buckled in the outside that absorbs cover 2, can keep manual pressing type breast pump cleaning inside.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of this utility model claim all according to the technical scheme and the design of above description.
