As shown in Figure 1, 2, this real sheet is novel comprises: kapillary 1, solution bottle 2, operation valve 3, sample introduction head 4, bottle stand 5, coupling arrangement 6, leading screw 7, cylinder 8, piston 9, gas bomb 10 and pipeline 11,12,13.Sample introduction head 4, solution bottle 2, bottle stand 5 are formed liquid taking device; One end and the piston 9 of coupling arrangement 6 join, and end joins with bottle stand 5 in addition.Place solution bottle 2 on the bottle stand 5, and make it with respect to sample introduction head 4 location.The installation orientation of piston 9 and solution bottle 2 are in the same way or oppositely.Leading screw 7 reaches jacking gear and the screw of its engagement constitutes by establishing on coupling arrangement 6, also can be gas, hydraulic lift etc.When piston 9 with solution bottle 2 in the same way the time, and when be the screw type jacking gear, when rotational lead screw 7, coupling arrangement 6 drive solution bottles 2 and piston 9 rise simultaneously, contact with sample introduction head 4 until solution bottle 2.The gas of piston 9 compressions enters gas bomb 10 through pipeline 11, generates on the occasion of little air pressure.The control of operation valve 3 follow procedures imports the air pressure of sample introduction head 4.If piston 9 is inverted installation with respect to solution bottle 2, then when solution bottle 2 rose, piston apparatus produced depressurization, generated little air pressure of bearing in the gas bomb 10.The process of the little air pressure of above-mentioned generation can realize that also promptly an end of coupling arrangement 6 and piston 9 join by the motion of sample introduction head 4, and in addition end joins with sample introduction head 4, and piston 9 and sample introduction head 4 are in the same way or oppositely.The simplest coupling arrangement 6 is plates of a rigidity.But, the rubber-like coupling arrangement has better effect: 1, help solution bottle 2 and contact with the airtight of sample introduction head 4; 2, the stroke of piston 9 is not subjected to the restriction of solution bottle 2 strokes.
As shown in Figure 2, sample introduction head 4 has the opening 14,15,16 of communicating with each other, and kapillary 1 is introduced from an opening 14, stretch out from another opening 16, and another opening 15 joins with pipeline 12; Perhaps sample introduction head 4 has 4 openings of communicating with each other 14,15,16,17, kapillary 1 is introduced from an opening 14, stretch out from another opening 16, and another opening 15 joins with pipeline 12, electrode 18 is housed in the opening 17, electrode 18 stretches out from opening 16, and opening 17 joins with cable 20, between sample introduction head 4 and solution bottle 2 sealing gasket 19 is arranged.
As shown in Figure 3, be A type elastic connecting device, it comprises: two web joints 21,22, spring 23, screw 24; Through hole 25 is arranged on the web joint 22, allow screw 24 to pass, web joint 21 and 22 joins through screw 24, the middle spring 23 of placing.Screw 24 1 ends are fixed on the web joint 21, and like this, web joint 22 can produce with respect to web joint 21 under the guiding of screw 24 and move.
As shown in Figure 4, the Type B elastic connecting device, it comprises: web joint 27,28, latch plate 26; Latch plate 26 1 termination web joints 27, termination web joint 28 in addition.
As shown in Figure 5, bottle stand 5 is the elastic bottle rack device.When use is rigidly connected,, can realize that also piston 9 is connected with elasticity between the solution bottle 2 if use elasticity bottle stand shown in Figure 5 simultaneously.Bottle stand 5 is the elasticity bottle stand, and it comprises: bottle seat 29, spring 32, pad 33; The opening 30 that is used to put into solution bottle 2 of one circle is arranged on the bottle seat 29, and opening has a cavity 31 for 30 times, and its diameter is greater than opening 30; Be placed with spring 32 in the cavity, a pad 33 is arranged between spring 32 and the opening 30, be used to support solution bottle 2 and prevent that spring 32 from entering opening 30.
The stereomutation that the volume of gas bomb 10 and piston apparatus produce determines the atmospheric pressure value that generates jointly.When using single gas bomb, generate monodrome air pressure.When using a plurality of gas bombs such as 1-10 and make it link to each other through operation valve mutually, then can change the gas bomb number that inserts pipeline 11, thereby produce many-valued air pressure.
As shown in Figure 6, the operation valve of the utility model on air pressure generating apparatus and liquid taking device pipeline can be established 1-10, and constitutes the operation valve group.For example establish two two-port valves 34,35, and form the operation valve group in operation valve 3 the place aheads.Pipeline 13 T-Ring border air pressure, pipeline 11 connects gas bomb 10.Pipeline 36 connects independently pneumatic supply.The introducing of independent pneumatic supply has increased dirigibility of the present utility model.
