Embodiment
As shown in Figures 1 and 2, specific embodiment of the present utility model is：It is whole that vacuum generator module 1 includes several
The vacuum generator of neat spread configuration, each vacuum generator has air intake and gas outlet, and gas circuit structure 2 then passes through inside
Gas circuit and the cooperation that is connected respectively with air intake and gas outlet are set.
Some vacuum generators are transversely arranged, before the gas circuit structure 2 is arranged on the vacuum generator module 1
Side；The interior lower end of the gas circuit structure 2 is provided with discouraged chamber 3, which is cylindricality；The outlet of some vacuum generators
Mouth is connected with the discouraged chamber 3, and the discouraged chamber 3 is provided with four leakage ports, and two of which leakage port is respectively symmetrically set
Put in the both sides of the gas circuit structure 2, two other leakage port is arranged on the front of the gas circuit structure 2.It is each described discouraged
Mouth adaptation is provided with muffler 5.
Also upper end is horizontally arranged with vacuum chamber 4 to the gas circuit structure 2 inside it, which is cylindricality；It is some described true
The air intake of empty generator is connected with the vacuum chamber 4, and the both sides of the gas circuit structure 2 are symmetrically arranged with and the vacuum
The air inlet that chamber 4 is connected.Pneumatic joint 6 is both provided with outside two air inlets.
Each vacuum generator of one integrated type vacuum generator module needs to be individually formed or breaking vacuum, in order to excellent
Change circuit air-channel system, usual multiple vacuum generators share the gentle gas road of electrical control；When formation or breaking vacuum, one
As in the case of, can produce and interfere between each vacuum generator.Specifically interference phenomenon is：1st, single vacuum generator produces vacuum
Meet the requirements, opening other vacuum generators, then each vacuum values can produce fluctuation, all vacuum generators of standard-sized sheet, then vacuum is born
Pressure can reduce；2nd, when closing vacuum, weak gas flow can be produced in gas circuit with quick breaking vacuum, but vacuum breaker air-flow is sharing
Interfered in circuit, so as to have impact on the vacuum breaker effect of each gas circuit；3rd, when a certain vacuum generator opens vacuum, gas
High pressure draught is produced in road, the shared gas channels design of tradition can produce portion gas leakage, cause suction nozzle during inoperative to produce
It is raw to blow.
The design is improved gas circuit design, and designs multiple leakage ports, is being vacuum formed or the process of breaking vacuum
The middle independence for ensureing each gas circuit exhaust, eliminates the interference between individual, reaches the stability and vacuum breaker efficiency of higher.This reality
In new, gas circuit structure 2 uses shared bleed passage of the chamber 3 as vacuum generator module 1 that lose heart, and is made using vacuum chamber 4
For sharing into gas passage for vacuum generator module 1；Air inlet is set respectively in the both sides of gas circuit structure 2, i.e. multi-group vacuum is sent out
Sharing for raw device uses both ends air inlet into gas passage, and is divided into two supply by exterior same tracheae.Air-flow is in 4 chamber of vacuum chamber
Moment momentum neutralizes in body, and tolerance of the air-flow from the air intake of vacuum generator to gas outlet is abundant；Two strands of constant speed air-flows exist
4 cavity of vacuum chamber occurs momentum and neutralizes, and eliminates vacuum change caused by high-speed flow instantaneous variation.Both ends air inlet at the same time avoids
The drawbacks of traditional one end air inlet, when one end air inlet, cause throughput in cylindricality because of the other end " dead angle " in cylindrical chamber
Gradually successively decrease in cavity, for one end air inlet scheme when gradually opening multiple vacuum transducers, the vacuum generator of distal end will in addition
There is deficiency of air and vacuum situation less than normal, in the case influence of the air pressure fluctuation to negative pressure of vacuum can become more sensitive,
Both-end air inlet can avoid the shortcomings that above-mentioned one end air inlet, and greatly improve negative pressure of vacuum stability and more vacuum generators at the same time
The stability of work.When multiple vacuum generators are opened at the same time, each vacuum generator can be obtained in vacuum chamber 4 enough and
Stable throughput, to ensure that each vacuum generator produces stable negative pressure of vacuum.When producing vacuum, pass through high pressure gas in gas circuit
Stream, negative pressure of vacuum is formed in the discouraged chamber 3 of the vacuum generator of unlatching, and on the other hand, air-flow is discharged by multiple leakage ports
Lose heart 3 cavity of chamber, will not leak in the vacuum generator passage that other are not opened.When a certain vacuum generator vacuum breaker,
Gas circuit in gas circuit structure 2 is closed while is blown into a small amount of air-flow to achieve the purpose that quick breaking vacuum, i.e., at this time whole
In a vacuum loop, existing big air-flow inputs to form negative pressure of vacuum, and has little airflow input vacuum breaker, in each generator passage
Influencing each other for isolated vacuum negative pressure and vacuum breaker air-flow is designed by leakage port circuit.
Vacuum generator module 1 includes the vacuum generator of multiple units, the electrical control that each vacuum generator shares
The gentle gas road of component, gas circuit use both-end air inlet, the mode that four leakage ports lose heart；It is multiple in vacuum generator module 1
Vacuum generator is connected so as to unify electric controling mode using self-control centerized fusion plate, and by bus interface, and gas
Line structure 2 shares gas circuit in arrival end, ensure that the simple for structure of vacuum generator module 1.
The utility model can be used for the technical field of vacuum generator gas circuit design.
