At the axle center of spring 28.It is respectively equipped with axle center hole, rotary knob rod 23 from two at the axle center of No. two thread barrels 22 and No. three thread barrels 25
It is passed through at the axle center hole of number thread barrel 22 and No. three thread barrels 25, the section of rotary knob rod 23 is in flat pattern, No. two thread barrels 22
It is flat in being adapted with rotary knob rod 23 with the axle center hole of No. three thread barrels 25, it can drive this when being rotated to rotary knob rod 23
The area of section of the axle center hole of two thread barrel rotations, No. two thread barrels 22 and No. three thread barrels 25 is more than the section of rotary knob rod 23
Air circulation may be implemented by the gap to form gap between axle center hole and rotary knob rod 23 in area.
It is equipped with end cap 5 positioned at the position of knob 6 on 4 outer wall of cylinder body, end cap 5 passes through screw thread, screw or other prior arts
In common connection type be connected with cylinder body 4.End cap 5 is equipped with knob hole, and the knob 6 exposes out of knob hole.Rotation
The rear end of the side of button 6 is equipped with outward flange 27, and the diameter of outward flange 27 is more than the diameter of knob hole, so as to by knob 6
Position is blocked, and prevents it from arbitrarily travelling forward.
The rear and front end of No. five springs 26 is withstood on respectively on knob 6 and No. three thread barrels 25, passes through No. five springs
26 effect is by knob 6 to sinciput.
Operating process is as follows：Piston 10 is pushed down on to the lower end of cylinder cavity 11 first when use, by cylinder cavity
Then feeding bottle 7 is mounted under cylinder body 4 by the air in 11 successively from No. two holes 30 and No.1 hole 15 to 12 lower section discharge of level board
On end, then 8 upper end horn mouth of milk tub is placed on breast, piston is then pulled up by piston handle 1 and piston rod 2
10, piston 10 is stuck in by 4 top edge of cylinder body by buckle structure, forms negative pressure, the air in feeding bottle 7 in cylinder cavity 11 at this time
It passes sequentially through No.1 hole 15 and No. two holes 30 to enter in cylinder cavity 11, to which 14 rear end of lateral aperture forms negative pressure, passes through negative pressure
Effect makes cylinder 17 move backward, is blocked until by No. two holes 30, forms negative pressure in feeding bottle 7 and milk tub 8 at this time, passes through negative pressure
Milk is sucked out for effect, flows into feeding bottle 7.
User can experience according to itself and go out milk effect adjusting knob 6, pass through knob 6 and adjust pressure value.When feeding bottle 7
Interior air pressure is too low when causing suction excessive, turn knob 6, passes through rotary knob rod 23 and drives No. two thread barrels 22 and No. three screw threads simultaneously
Cylinder 25 rotates, and makes No. two thread barrels 22 and No. three thread barrels 25 while moving backward, passes through No. two thread barrels 22 and No. three screw threads
Cylinder 25 respectively compresses No. three springs 28 and No. four springs 24, and the elastic force of No. three springs 28 and No. four springs 24 is made to increase, No. four
After the elastic force of spring 24 increases, make suction smaller in feeding bottle 7（I.e. higher atmospheric pressure value）Cylinder 17 can be driven backward
It moves and blocks No. two holes 30；After the elastic force of No. three springs 28 increases, when atmospheric pressure value interior in feeding bottle 7 is too small, pass through
The elastic force of No. three springs 28 can be open-top backward by cylinder 19, and external air passes sequentially through knob hole, No. three thread barrels 25
Axle center hole, the axle center hole of No. two thread barrels 22, centre bore 29, the axle center hole of No.1 thread barrel 16 and No.1 hole 15 enter feeding bottle 7
It is interior, so that the atmospheric pressure value in feeding bottle 7 is increased, so as to reduce the suction of milk tub 8.When 7 inner suction of feeding bottle is too small（That is atmospheric pressure value
It is excessive）When, turn knob 6 drives No. two thread barrels 22 and No. three thread barrels 25 to rotate and moves forward by rotary knob rod 23, from
And No. three springs 28 and No. four springs 24 are unclamped, so that the elastic force of No. three springs 28 and No. four springs 24 is reduced；No. four 24 bullets of spring
After power reduces, cylinder 17 is pushed forward by the effect of No.1 spring 13, to make No.1 sealing ring 21 from No. two holes 30
It leaves, so as to make the air in feeding bottle 7 enter in cylinder cavity 11, so that the air pressure in feeding bottle 7 is further decreased, then
14 rear end part suction of lateral aperture increases, and so that cylinder 17 is moved backward, is sealed up until by No. two holes 30.
In elicitation process, as feeding bottle 7 progresses into milk, the volume of air in feeding bottle 7 reduces, to make feeding bottle 7
Increase with air pressure in 14 rear end of lateral aperture, cylinder 17 travels forward, and to make No. two holes 30 expose, the air in feeding bottle 7 enters
In cylinder cavity 11, the air pressure in feeding bottle 7 is made to reduce, restored to original pressure value.After sucking due in milk tub 8 still
So there are suction, and sense can be torn to breast generation by directly removing, or even cause breast pain.When using the present invention, by knob 6 to
After push, by the effect of rotary knob rod 23 that cylinder 19 is open-top backward, air is got enter into feeding bottle 7 and milk tub 8, to
The air pressure in milk tub 8 is set to restore to atmospheric pressure, to which milk tub 8 directly can be naturally detached from from breast, so as to avoid
Tear sense and pain sense.
In the present invention, by the effect of cylinder cavity 11, play the role of negative pressure compensating, in whole work process,
Atmospheric pressure value in cylinder cavity 11 is consistently less than the atmospheric pressure value in feeding bottle 7, and the size in 11 space of cylinder cavity can be according to feeding bottle 7
Its volume is rationally arranged in size and actual use situation.
Buckle on piston 10 and piston rod 2 can there are many embodiments, hereinafter specifically one by one by various embodiments
It outlines.For ease of narration, be set in piston 10 and piston rod 2, the direction towards cylinder axle center be it is interior, separate cylinder axle center
