Logical portion, the public interconnecting part are provided with piston, and the piston is for realizing air storage chamber and secondary air intake duct or the company for spraying air flue
Logical operation, when air inlet has compressed air to enter, air storage chamber and secondary air intake duct are in connected state, then air storage chamber and injection gas
Road is in disconnected state；When air inlet does not have compressed air to enter, air storage chamber and secondary air intake duct are in disconnected state, then
Air storage chamber and injection air flue are in connected state.
Air inlet is connected by the device using main air intake with vacuum chamber, while secondary air intake duct is used for air storage chamber and air inlet
Connection of the air flue for air storage chamber and vacuum chamber is then sprayed in the connection of mouth.When air inlet is passed through compressed air, compressed air is logical
It crosses main air intake and enters vacuum chamber, to be discharged from gas outlet, and then make to generate vacuum in vacuum chamber, to realize absorption behaviour
Make.Meanwhile piston is moved under the action of compressed air, so that air storage chamber be made be connected to secondary air intake duct, then air storage chamber and
Injection air flue is in closed state, and compressed air enters in air storage chamber at this time.When air inlet does not have compressed air to enter, piston
It moves at secondary air intake duct, so that secondary air intake duct be made to be in closed state, then sprays air flue and be in connected state with air storage chamber,
The indoor gas of gas storage enters vacuum chamber by spraying air flue, to realize quick vacuum breaker operation.
Further, the public interconnecting part is provided with adjusting screw, the adjusting screw is for realizing injection air flue
Air-blowing quantity control operation.
Further, the gas outlet is provided with muffler.
The beneficial effects of the present invention are:
1, the device has blowing function, it can be achieved that quick vacuum breaker, avoids the adherency of workpiece, while structure is simple,
A possibility that reducing gas leakage, has ensured that stablizing for work carries out；
2, the setting for adjusting screw, improves device flexibility, it is easy to accomplish the device reasonable disposition under a variety of environment；
3, the setting of muffler, reduces operating noise, expands the scope of application of device, realizes device practicability
Extension.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of vacuum generating device with blowing function of the invention；
In the figure, it is marked as air inlet 1, main air intake 11, secondary air intake duct 12, vacuum chamber 2, gas outlet 3, air storage chamber 4, injection
Air flue 5, piston 6 adjust screw 7, muffler 8.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1,11 one end of main air intake connects air inlet 1, the other end connects vacuum chamber 2.Based on secondary air intake duct 12
One branch of air intake duct 11, then the other end of secondary air intake duct 12 connects air storage chamber 4.Air storage chamber 4 passes through injection air flue 5 and vacuum
Chamber 2 is connected to.At this point, secondary air intake duct 12, injection air flue 5 and air storage chamber form public connected region.It is provided in the public connection area
Piston 6, as shown, the public connected region is the channel to match with piston cross-section face, secondary air intake duct 12 is located at public connection
