Five, the specific embodiment:
Embodiment:
As shown in Figure 1, reservoir 1,2, bottle stopper 3, air filter 8, electric contact negative pressure of vacuum table 9, electromagnetic valve 10,11, negative pressure pump 12, motor 13, gas circuit pipeline 14, suction tube 15, its characteristics are: the middle end of upper section of the inlet pipe connection 4 of the left end of reservoir 1 is equipped with electromagnetic valve 10, electromagnetic valve 10 1 ends are connected with the inlet pipe connection 4 of reservoir 1, the other end is connected with suction tube 15, electric contact negative pressure of vacuum table 9 is equipped with in the upper end of the connection tube 5 of giving vent to anger of the right-hand member of reservoir 2, the right-hand member of electric contact negative pressure of vacuum table 9 is equipped with electromagnetic valve 11, the humidity sensor 7 of electromagnetic valve 11 and left end, air filter 8, the negative pressure pump 12 of electric contact negative pressure of vacuum table 9 and right-hand member connects logical mutually, the connection tube 5 of giving vent to anger reaches dress anti-overflow device 6 on the pipe in the reservoir 2, electromagnetic valve 10 and relay J
2Contact J

Relay J is passed through in electromagnetic valve 11 and motor 13 parallel connections in Fig. 2 control circuit schematic diagram AC power circuit
1Two contact J
1-1, J
1-2 connect alternating current power supply, and electromagnetic valve 10 passes through relay J
2Point J
2-1 connects alternating current power supply.The duty of electromagnetic valve 11 and vacuum motor 13 is synchronous in automatic control circuit, at contact J
1-1, J
1Promptly work simultaneously after-2 closures, if electromagnetic valve 10 do not open, will form negative pressure in the reservoir 1,2, when negative pressure reaches set definite value, negative pressure pump 12 stops, and electromagnetic valve 11 also cuts out simultaneously, like this negative pressure just in reservoir 1,2 the quilt storage get up.
Alternating current power supply is through transformator T blood pressure lowering, commutator DZ rectification, and capacitor C1 filtering is also set up the straight source of direct current on its both positive and negative polarity.K2 is replaced by the contact of the dynamic and static pointer of electric contact negative pressure of vacuum table, when deflection throw of pointer and negative pressure are regulated pointer and are joined, and 2 connections of expression K switch, at this moment the positive pole of capacitor C 2 links to each other with the circuit negative pole, this makes audion BG end, relay J 1 outage, contact J
1-1, J
1-2 disconnect, electromagnetic valve 11 and motor 13 outages, and negative pressure pump stops.When the K2 disconnection, the dc source anode is set up voltage through resistance R 1 on capacitor C 2, make audion BG conducting, relay J by stabilivolt WD
1Work, its contact J
1-1, J
1-2 closures, electromagnetic valve 11 and negative pressure pump 12 work.Each negative pressure pump 12 work have the regular hour delay, this is when K2 disconnects, voltage on the capacitor C 2 needs the regular hour just can set up, voltage on capacitor C 2 rises so that make stabilivolt WD conducting and audion BG conducting, J1 work makes negative pressure pump 12 work, adopts this control mode can avoid disconnecting the unfavorable situation that negative pressure pump 12 frequent startings are stopped because of the contact of K2 contact.Institute so that negative pressure pump 12 is restarted, guarantees continuing of negative pressure by resistance R 1, capacitor C 2, stabilivolt WD decision time delay in a suitable time range.
The effect of holding circuit is if liquid enters in the humidity sensor 7, makes humidity sensor 7 conductings, and audion BG base stage connects power cathode and ends immediately; relay J 1 outage; negative pressure pump 12 quits work, and avoids liquid to suck and causes damage, plays the effect of second protection.
Hand switch S1, foot are stepped on switch S 2 control relay J2, contact J during its conducting in the imbibition control circuit
2-1 closure, electromagnetic valve 10 is opened just can be aspirated.Hand switch S1 closure makes electromagnetic valve 10 keep long and opens, and can be used for the liquid drain like this.
