The specific embodiment
Fig. 1 illustrates the method flow diagram that among the present invention liquid is flowed to storage box from cassette for supplying.The method remains that the liquid in the described storage box is uninterrupted, may further comprise the steps:
In step 110, the air pressure in the storage box (leakproof tank) is dropped to air pressure less than cassette for supplying (leakproof tank), make flow of liquid in the described cassette for supplying in storage box.
In step 120, when the amount of liquid in the described cassette for supplying arrives the alert if of setting, control air pressure in the described storage box it is equated with air pressure in the described cassette for supplying, described cassette for supplying stops to described storage box influent and with filling liquid in the described cassette for supplying.
In step 130, detect the amount of liquid of described storage box, when the alert if of the described storage box of arrive not setting with described cassette for supplying in filling liquid.
Fig. 2 illustrates and moves the liquid method flow diagram among the present invention in another embodiment.In step 110, make the flow of liquid in the described cassette for supplying also carry out following operation to the process in the described storage box: existing liquid in the described storage box is moved to the exit.
Fig. 3 illustrates and moves the liquid method flow diagram among the present invention in another embodiment.In the step 130, detect the operation of the amount of liquid of described storage box and can carry out following operation: detect the threshold value whether amount of liquid in the described storage box arrives setting, if so, then arrive and set alert and if send alert notice, with filling liquid in the described cassette for supplying.Otherwise do not arrive.The alert if of described setting comprises liquid level threshold value or liquid capacity threshold value etc.Described liquid level threshold value or liquid capacity threshold value can be 0 or other values.Remaining has liquid in the storage box, thereby makes the liquid in the storage box can continually flow into the exit.
Fig. 4 illustrates and moves the liquid method flow diagram among the present invention in another embodiment.In step 130, with the concrete operations of filling liquid in the described cassette for supplying be: liquid feeding or be replaced by the cassette for supplying of liquid feeding in the described cassette for supplying.By the operation of this filling liquid, can remain that the liquid in the described storage box is uninterrupted.
The present invention can realize by repeatedly carrying out above operation the uninterrupted movement of liquid.Comprise the uninterrupted of liquid in the storage box, and liquid in the storage box is uninterruptedly moved to the exit.Those skilled in the art also can make other distortion and modification accordingly, but all should be included in the protection domain that this claim covers.
Fig. 5 illustrates the method application example of moving liquid among the present invention.
When initial condition, there is liquid in the fluid supply tank, there is not liquid in the liquid storage case, valve V1 opens, and valve V2 closes.Before working first, utilize other accessory appliancess (such as disposable syringe) in the T6 exit air pressure in the storage box to be reduced, pressure in the cassette for supplying is just large than the pressure in the storage box at this moment, so that the flow direction storage box in the cassette for supplying is full of liquid among pipeline T1, T2, the T3.(liquid level of liquid is higher than the liquid level of liquid in the cassette for supplying in the cassette for supplying according to siphon principle, the generation pressure difference) liquid will flow to from cassette for supplying in the storage box, until storage box is full of liquid, also can be full of liquid (liquid level among liquid level and the pipeline T2 is contour) among the pipeline T5 simultaneously.In the time liquid need to being moved to exit shown in Fig. 5 from storage box, 22 logical valve V2 (normally closed) open, and pump is started working liquid from the liquid storage case simultaneously, moves to liquid outlet by pipeline T4, T7, T8, T9.
When the liquid in the cassette for supplying all moved in the storage box, sensor can give the alarm, and valve V1 closes, and can add liquid or change one bottle of new cassette for supplying that is full of liquid in fluid supply tank this moment.In liquid feeding or replacing cassette for supplying process, moving surges does and can uninterruptedly carry out.Because after valve V1 closes, the siphon condition is destroyed, and the liquid among the pipeline T2 just can not flow in storage box again, and pump can continue to extract out liquid from storage box.After liquid feeding or the end of replacing cassette for supplying, valve V1 opens, and sets up so again the siphon condition, and liquid can flow in the storage box from cassette for supplying again, thereby remaining has liquid in the storage box, realized uninterruptedly moving continuously liquid.
Fig. 6 illustrates the constructional drawing of moving liquid device among the present invention.Comprise: cassette for supplying 1, storage box 2 and controller 3.
Cassette for supplying 1 and storage box 2 communicate by pipeline, are provided with the controller 3 that carries out air-pressure controlling in storage box 2.By described controller 3 control air pressures, make the air pressure of described storage box 2 drop to air pressure less than described cassette for supplying 1, then the flow direction storage box 2 in the cassette for supplying 1.
When alert if that the amount of liquid in the cassette for supplying 1 arrive to be set, such as liquid level threshold value or liquid capacity threshold value etc., this threshold value can be 0 or other constants.Controller 3 needs the air pressure of the described storage box 2 of control that it is equated with air pressure in the described cassette for supplying, and then described cassette for supplying 1 will be no longer to described storage box 2 influents and with filling liquid in the described cassette for supplying 1.Controller 3 can comprise valve, also can realize by other means air-pressure controlling, such as computer controlled.At this moment, cassette for supplying 1 the alert if of the described cassette for supplying of arrive setting and the alert if that do not arrive the described storage box of setting with described cassette for supplying in filling liquid.
Fig. 7 illustrates the structure drawing of device of moving liquid in another embodiment of the present invention.On the basis of Fig. 6, further comprise: move liquid module 5 and outlet 6, by moving liquid module 4 liquid in the storage box 2 is moved to outlet 6.
Fig. 8 illustrates the structure drawing of device of moving liquid in another embodiment of the present invention.Different from the device shown in Fig. 6 is also further to comprise: sensor 4, for detection of amount of liquid in the cassette for supplying 1 and in the described storage box 2, send alert notice when described amount of liquid arrives the alert if of setting.Described alert if comprises liquid level threshold value or liquid capacity threshold value etc., and setting value can be 0 or other constants.
In addition, described cassette for supplying is by liquid feeding or be replaced by the cassette for supplying of liquid feeding and realize that liquid injects.So, can remain that the liquid in the described storage box 2 is uninterrupted.
The present invention can pass through the cooperation of cassette for supplying 1, storage box 2 and controller 3, repeatedly carries out aforesaid operations, to realize the uninterrupted movement of liquid.Those skilled in the art also can make other distortion and modification accordingly, but all should be included in the protection domain that these claims cover.
The present invention moves on to storage box with liquid from cassette for supplying, and remaining has liquid in the storage box, has realized the uninterrupted duty of storage box, to satisfy the needs of not shutting down production in self-reacting device.In addition, owing to having remained liquid in the storage box, liquid moves in the process of outlet in storage box, also can guarantee continual continuous working.
