The reliable operation degree of the vacuum pump for designing while also improving integrated pump valve in road.
The course of work of the vacuum pump of integrated pump valve of the present invention is, when air-breathing, asepwirator pump 7 drives connecting rod 8, will
For leather cup 4 toward drop-down, gas chamber 43 is interior to form negative pressure, carries out aspiratory action, the gas between the humalacter and human breast of breast pump
Enter gas chamber 43 by air inlet 11, breather cheek valve 21, air inlet 31；Then asepwirator pump 7 drive connecting rod 8 by leather cup 4 up
It pushes away, carries out outlet movement, is i.e. gas in gas chamber 43 passes through venthole 32, unidirectional air outlet valve 22 and two outlet passageway rows
Out.Alternately aspiratory action and outlet act repeatedly, so that certain negative pressure is formed in gas chamber 43, with air inlet 11
The breast pump being connected sucks.When the negative pressure in aspiratory action, outlet movement alternately a period of time, gas chamber 43 reaches
When specific threshold, solenoid valve 6 is started to work, and valve core of the electromagnetic valve leaves valve port 611, and outside air can pass through side aeration aperture 612
Valve port 611 is entered, and then enters the inflatable chamber 54 of shell 5, then passes through inflation mechanism (leather cup aeration aperture 44, intermediate inflation
Hole 33, aeration aperture 23, the second end 142 of air drain 14, air drain 14) enter suction mechanism, to reduce the negative pressure in gas chamber 43.Electricity
The working time of magnet valve 6 can set and adjust by adjusting the program of solenoid valve 6, control to realize to inflationtime
System, and inflationtime is controlled, that is, controlling inspiratory duration and intensity.Different people can be according to itself
The case where voluntarily adjust corresponding suction intensity and suction time.
In addition, the inflation mechanism of the vacuum pump of integrated pump valve of the present invention, using the spool of solenoid valve 6 with electromagnetic coil
It powers on or powers off and abut or leave valve port 611, so that outside air cannot or can be entered by side aeration aperture 612
Inflatable chamber 54, is designed in this way, and realizes that (charging valve includes the side aeration aperture 612, spool and valve port by charging valve
611) it is located on solenoid valve 6.If charging valve is located at leather cup 4 perhaps on valve sheet 2 for example, in leather cup 4 or valve sheet
On 2 be arranged a raised film, the spool of solenoid valve 6 as electromagnetic coil powers on or powers off and opens or leave the film,
To realize opening or closing for charging valve, since valve sheet 2 and leather cup 4 are usually to be made of rubber elastomeric material, charge valve
The opening and closing repeatedly of door will affect its service life and reliable operation degree, and charging valve is located at the design on solenoid valve 6 by the present invention, is filled
The reliable operation degree of mechanism of qi structure and service life.On the other hand, the present invention does not have to consider by the way that charging valve to be located on solenoid valve 6
