Embodiment
The utility model is described in further detail below by embodiment combination accompanying drawing.
Refer to shown in Fig. 1,3,4, a kind of milk water collecting device embodiment of breast pump, including bottle 1, be connected to it is described
Threeway 2 on bottle 1, the threeway 2 by the connecting portion (diagram using threaded connection) for connecting bottle, for connecting tracheae
The gas cup and the breast cup 4 for contacting human body (breast) for accessing negative pressure are formed, and middle pipe 17, middle pipe are provided with the connecting portion
17 bottoms are provided with check valve 15, and the gas cup, middle pipe 17, the connection of breast cup 4 form three-port structure；The check valve 15 is act as
Prevent air-flow from entering threeway and allow milk to be discharged out of threeway.Described gas cup includes：The gas cup main body of hard bowl structure
5th, lid is located in the gas cup main body 5 to form the gas cup lid 3 of closed cavity, be arranged in the gas cup main body 5 and edge quilt
The gas cup lid 3 forms the silica gel gas cup 6 on annular seal border with the gas cup main body 5 extruding.The shape of silica gel gas cup 6 with
The gas cup main body 5 is adapted to, that is, is all that bowl-shape simply size is slightly smaller.The tracheae of its inner chamber is communicated with outside the gas cup lid 3
Joint 8, the bottom of gas cup main body 5 are provided with the opening 18 (such as Fig. 2,4) connected with the middle pipe 17, and the silica gel gas cup 6 will
The cavity isolation that the cavity of the connection of opening 18 connects with the gas-tpe fitting 8；In other words, silica gel gas cup 6.By gas cup lid 3
Closed cavity is formed with gas cup main body 5 and is divided into two parts, and a part is communicated to breast pump main frame by 8 external tracheae of gas-tpe fitting
(generation suction), another part connect the inner space of breast cup 4 by the opening 18 of the bottom of gas cup main body 5.Connect in gas-tpe fitting 8
Silica gel gas cup 6 does to the side of gas-tpe fitting 9 and shrinks-reply repeatedly in the presence of the suction entered, and-shrinking again-replys ... again
Motion；Corresponding suction is formed in the side of 5 bottom opening of gas cup main body 18 in the process, is acted on and conducted by threeway
Suction is formed to breast cup, milk suctions out in the breast that will be contacted with breast cup.Precisely due to the buffer action of silica gel gas cup 6,
Even if milk enters gas cup main body 5 by the opening 18 can not possibly also reach gas-tpe fitting 9, that is, realize the conduction of suction

Structure booster action, reduce the self-deformation in work process.
During implementation, as shown in Fig. 1,4,5, a kind of milk water collecting device of breast pump, the check valve of the bottom of middle pipe 17
15 include the main bodys with a lateral plane, are provided with the lateral plane described in outlet hole 14, diaphragm button bit 13 and card fit over
Diaphragm 16 on diaphragm button bit 13, the diaphragm 16 covers the outlet hole 14, and (outlet hole 14 is the hole that multiple single holes are formed
Set, the diaphragm 16 cover all single holes of the outlet hole 14).The diaphragm 16 is symmetrically thin in vertical direction center line
Membrane structure, its medial surface top are located at center line and are provided with the locating pin 21 matched somebody with somebody with the diaphragm button bit 13 card；The diaphragm button bit
13 directly over the center line of the setting area of outlet hole 14.Diaphragm 16 is tight under the suction function of breast pump aspiration procedure
Closely connected conjunction outlet hole 14 forms sealing.In the deflation course of breast pump, the inner chamber of breast cup 4 and atmosphere, the milk in breast cup
Water pushes diaphragm 16 open because gravity flows down naturally, by outlet hole 14 and flows into bottle 1.It is perpendicular that diaphragm button bit 13 is located at the outlet hole 14
The surface of straight middle separated time, is advantageous to diaphragm and is opened naturally under gravity state.And released after the aging of diaphragm 16 can be reduced
The problem of, improve durability.
As shown in Fig. 1,4,5, specifically, diaphragm button bit 13 is located at directly over the 14 vertical middle separated time of outlet hole, so
Avoid the diaphragm button bit 13 of prior art such as and be arranged on the vertical middle separated time side on the upper side of outlet hole 14, diaphragm 16 can be caused by inclined
Torque, the problem of causing stress aging.
As shown in Fig. 1,4,5,7,8, during implementation, at the top in the outside of diaphragm 16, provided with along top edge convex
The setting muscle 20 (such as Fig. 7) risen, 16 other positions of thickness ratio diaphragm of setting muscle 20 part are thick, so convenient in assembling
Hand assembled (feel is more preferable when entering diaphragm 16 with hand pressure, helps to be pressed into place, reference picture 8) and prevents edge curl in place,
In use, the both sides of diaphragm 16 (opposing diaphragms 16 pass through the both sides of the axis of diaphragm button bit 13) curling is avoided to turn over
Turn, the time, which has been grown, causes the overall curling failure of diaphragm 16, and concrete principle is because the thickness of setting muscle 20 blocks greatly vertical volume
It is bent.
As shown in Figure 7,8, the multiple salient points being intervally arranged are provided with the lateral surface surface of diaphragm 16, conduct oneself with dignity for increase,
Reinforcement structure intensity etc..
Specifically, as shown in Fig. 1,4,5, a kind of milk water collecting device of breast pump, the check valve 15 is absolute construction,
The check valve 15 is set in the bottom of middle pipe 17.
As shown in Fig. 1,2,3,5, a kind of milk water collecting device of breast pump, the gas cup main body 5 is located in the threeway 2
Portion side, it is obliquely installed in 15-45 degree.The milk water collecting device connection tracheae that the structure is easy to, facilitates each accessory to set, increase
Installation space.
Specifically, as shown in Fig. 1,2,3,5, the axis of gas cup main body 5 is in 90 degree with the horn mouth axis of breast cup 4
Vertically.I.e. such as Fig. 1, gas cup main body 5 is on the milk water collecting device of breast pump about in 30 degree of inclinations.
Above content is to combine specific embodiment further detailed description of the utility model, it is impossible to is assert
Specific implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be considered as category
