Description
Technical field
The present invention relates to nursing implements technical field, a kind of breast pump with counterflow-preventing function is refered in particular to.
Background technology
Breast pump in the market is to produce negative pressure in the outer cup of breast pump mostly as shown in Figure 1, so as to compel
The breast compression of user is set to go out milk.The interior cup 20 of breast pump is buckled in outer cup 10 by clasp 30；Ventilation hole post
101st, 102,103 are connected with main frame.The inflation of hole post 101,102 of ventilating, air-breathing form the massage to breast.Ventilation hole post 103
Air-breathing form negative pressure in outer cup, so as to the milk of lactation person be suctioned out from breast.But, existing structure is often held
Easily make milk along the ventilation adverse current of hole post 103 in main frame；So as to cause the damage of main frame.
The content of the invention
Present invention solves the technical problem that being to provide a kind of breast pump；Solve the problems, such as that milk reversely flows back towards main frame.
The present invention solve above-mentioned technical problem technical scheme be：
The outer cup of the breast pump is provided with air pressure adjustment chamber；Described air pressure adjustment chamber connects with outer cup；In air pressure
Regulation is provided with an air bag in chamber；Described air bag is connected with main frame gas；During air bag Volume Changes, between air pressure adjustment chamber and air bag
Spatial volume change；So as to adjust the air pressure in outer cup.
Described air pressure adjustment chamber is made up of upper lid and lower cover.
The lower cover in described air pressure adjustment chamber is connected by intercommunicating pore with outer cup.
Described air bag opening can be connected by the ventilation hole post being arranged on upper lid with main frame.
Described air bag is made up of the flexible glue material with elastic-restoring force.
The upper lid in the air pressure adjustment chamber is realized being tightly connected with lower cover by buckle.
Described intercommunicating pore is more than one.
The present invention by upper lid, lower cover, air bag setting；By outer cup shaped into space and main frame between by air bag every
Absolutely；The milk in outer cup is avoided to damage main frame to main frame from ventilation hole post adverse current.Due to air bag vacantly in Shang Gai with
Cap-shaped into space in, and air bag is made up of flexible glue material；Thus can be very good to respond the air-breathing of main frame, inflate；Use effect
On fruit preferably.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is existing breast pump sectional view；
Fig. 2 is to set the outer sectional view of cup 10 of breast pump of the invention；
Fig. 3 is to set the outer main view exploded view of cup 10 of breast pump of the invention；
Fig. 4 is to set the outer three-dimensional exploded view of cup 10 of breast pump of the invention；
Fig. 5 is to set the outer stereogram of cup 10 of breast pump of the invention；
Fig. 6 is to set upper lid 105 of the invention and the three-dimensional exploded view of air bag 106.
Part accompanying drawing figure number explanation：
Outer cup 10, lower cover 104, upper lid 105, air bag 106, intercommunicating pore 107, hole post 108 of ventilating
Specific embodiment
As shown in figures 2-6, lower cover 104 is connected with the outer cup 10 of breast pump of the invention, between lower cover 104 and outer cup 10
It is provided with an intercommunicating pore 107 (multiple intercommunicating pores can also be set as needed).It is additionally provided with lid 105 and lower cover 104
It is tightly connected.Hook 1051 is set on upper lid 105, projection 1041 is set on lower cover 104；Lead between upper lid 105 and lower cover 104
Cross hook 1051 and realize that snap is connected with projection 1041.Certainly upper lid 105 can also be connected with lower cover 104 using others
Mode, only need to realize being tightly connected.
Air bag 106 is placed in the space that lid 105 is formed with lower cover 104；It is logical on the opening portion of air bag 106 and upper lid 105
Stomata post 108 is connected.In addition to opening portion is fixed, remainder all can vacantly in upper lid 105 and lower cover 104 for foregoing air bag 106
In the space of formation.The generally flexible glue material of air bag 106 is made.Ventilation hole post 108 is connected by tracheae with main frame.
When main frame passes through tracheae air-breathing, the air inside air bag 106 is extracted, volume-diminished；So that upper lid 105 is with
The part that the space that lid 104 is formed is not taken by air bag 106 becomes big.Because outer cup 10 is connected with the space；Synchronously cause outer
Air pressure in cup 10 diminishes, and suction is formed to breast；Milk is suctioned out.Now, the space due to outer cup 10 and master
Between machine, completely cut off by air bag 106；So as to be prevented effectively from milk adverse current in main frame.
Above example is the description to further specific embodiment of the invention, not limitation of the present invention；It is all
The equivalent transformation that can be obtained according to foregoing description all should be within protection scope of the present invention.
