Embodiment
Referring to the accompanying drawing for showing the embodiment of the present invention, the present invention is described in more detail.However, the present invention can be with
Many multi-forms are realized, and should not be construed as being limited by the embodiment herein proposed.On the contrary, propose that these embodiments are
In order to reach abundant and complete disclosure, and those skilled in the art are made to understand the scope of the present invention completely.These are attached
In figure, for clarity, the size and relative size in layer and region may be exaggerated.
With reference to figure 3-4, the invention provides a kind of vacuum flow and the automaton of vacuum, installed in a vacuum
The atmospheric pressure of cavity 1 is flowed through in passage, for being controlled to vacuum flow.Vacuum flow provided by the invention and vacuum
Automaton, the size for the passage that atmospheric pressure flows through is automatically adjusted according to the size of atmospheric pressure, so as to realize vacuum flow
Regulation, and the present invention it is simple in construction, occupy little space, it is cost-effective.
Specifically, a kind of vacuum flow and the automaton of vacuum include a round iron plate 2, opened on iron plate 2
It is provided with a deep-slotted chip breaker 21 so that the center position of iron plate 2 forms a flexible shell fragment 22, deviates when shell fragment 22 is pressurized
During the plane at the place of iron plate 2, a larger pressure channel is formed on the center of iron plate 2；Certainly, the formation of shell fragment 22 can also lead to
Cross other modes to realize originally, such as one first can be directly opened on iron plate 2 compared with big hole, then on the circular hole position of iron plate 2
One shell fragment 22 is installed, can as the case may be design, not be restricted herein.It is small that one is additionally provided with the center of shell fragment 22
Hole 23, when shell fragment 22 is in initial position, aperture 23 is used as a smaller pressure channel, wherein setting of the aperture 23 on shell fragment
Position and big I design according to tool situation, are not restricted herein.The present invention is by iron plate 2 come instead of of the prior art
Ball control device or unidirectional control valve device are controlled to vacuum flow, and its thickness is smaller, and space-consuming is smaller, and save
Save raw material.
In the present embodiment, the vacuum flow and the automaton of vacuum also include a section bar 4, the shape of section bar 4
Shape and size flow through the shape size of passage to determine by the atmospheric pressure of vacuum cavity 1.It is provided with the center of section bar 4
One ladder hole, ladder hole include big footpath through hole 5 and path through hole 6, and big footpath through hole 5 is towards vacuum cavity 1, path through hole 6
Towards the external world.In the present embodiment, the diameter of iron plate 2 is less than or equal to the diameter of big footpath through hole 5, and the diameter of shell fragment 22 is more than or equal to
The diameter of path through hole 6；Iron plate 2 is arranged in big footpath through hole 5, and is arranged on big footpath through hole 5 and path by a fastening spring 3
At the boundary position of through hole 6, and fastening spring 3 is pressed on the position on iron plate 2 in addition to deep-slotted chip breaker 21 and shell fragment 22；Wherein,
Iron plate can be also installed in section bar 4 by other means, be not restricted herein.The section bar 4 for being provided with iron plate 2 to be mounted directly to very
The atmospheric pressure of cavity body 1 is flowed through in passage；Certainly, the vacuum flow and the automaton of vacuum can also be not provided with section bar
4, the atmospheric pressure of vacuum cavity 1 can now be flowed through to the structure type that passage is designed to ladder hole as described above, iron plate 2
The atmospheric pressure that to be mounted directly to vacuum cavity 1 is flowed through in passage, can as the case may be designed, is not restricted herein.
The invention provides a kind of vacuum flow and the automaton of vacuum, its specific work process are as follows：Greatly
Air pressure is entered in vacuum cavity 1 from path through hole 6, big footpath through hole 5 successively, and in the case where flow is little, atmospheric pressure can be straight
Connect small holes 23 to enter in vacuum cavity 1, now vacuum flow is smaller；When the change of atmospheric pressure flow is big, shell fragment 22 is in air
Pressed off in the presence of pressure, the size that atmospheric pressure flows through passage is the size of path through hole 6, bigger flow is entered vacuum
In cavity 1, now vacuum flow is larger, so as to improve operating efficiency.
