With reference to Fig. 2 and Fig. 3 referring to Fig. 1, the reagent filling device 100 of the embodiment of the utility model one, including intrusion pipe 110th, pouring valve 120, stapler 130, the first detection unit 140, the second detection unit 150 and control unit 160.

Wherein, the main function of intrusion pipe 110 is, for injecting reagent 8 into perfusion container 9.The mouth of pipe of intrusion pipe 110 Stretch into the bottleneck 91 of perfusion container 9.Preferably, perfusion container 9 is perfusion bucket.It is of course also possible to it is other rigid containers.

In the present embodiment, intrusion pipe 110 is circular hard tube.It is, of course, understood that the utility model is to intrusion pipe 110 concrete structure is not construed as limiting, and can think suitably to irrigate tubular construction using those skilled in the art.

Wherein, pouring valve 120 is arranged on intrusion pipe 110.The main function of pouring valve 120 is, on or off Intrusion pipe 110；That is, when pouring valve 120 is opened, intrusion pipe 110 is turned on, and reagent 8 injects perfusion along intrusion pipe 110 to be held In device 9；When pouring valve 120 is closed, intrusion pipe 110 is turned off, and reagent 8 is trapped, and the reagent 8 of the rear end of pouring valve 120 can not edge Intrusion pipe 110 is injected in perfusion container 9.

In the present embodiment, pouring valve 120 is magnetic valve.It is, of course, understood that pouring valve of the present utility model 120 are not limited to magnetic valve, can also be the non-manual valve of other acceptable controls.

Wherein, stapler 130 is sheathed on outside intrusion pipe 110.The main function of stapler 130 is, for perfusion container 9 Bottleneck 91 coincide, so that whole reagent filling device 100 is supported on bottleneck 91.When the sleeve of stapler 130 is in bottleneck 91 When outer, intrusion pipe 110 is extend into bottleneck 91.The concrete structure of stapler 130, those skilled in the art can be according to actual feelings Condition is set, and will not be repeated here.

Wherein, the first detection unit 140 is arranged on stapler 130.The main function of first detection unit 140 is to use Whether it is enclosed on outside bottleneck 91 in detection stapler 130；That is, when stapler 130 be not enclosed on bottleneck 91 it is outer when, first detection Unit 140 is not responding to；And when stapler 130 be enclosed on bottleneck 91 it is outer when, the first detection unit 140 responds.

It is highly preferred that the first detection unit 140 includes being used to detect the identical detection mould that stapler 130 coincide with bottleneck 91 Block.

With reference to referring to Fig. 4, it is preferable that the detection module that coincide includes at least one first sensor 141, the first sensor Whether 141 bottoms 131 for being used to detect stapler 130 contact with shoulder 92；If the bottom 131 of stapler 130 connects with shoulder 92 Touch, then illustrate that now stapler 130 and bottleneck 91 are identical.

Preferably, first sensor 141 is at least two, and is uniformly distributed.The bottom of stapler 130 can so be avoided Side contacts with shoulder 92, and opposite side does not contact with shoulder 92 and causes false triggering, responds by mistake；And then further improve and coincide The accuracy of detection module.

In the present embodiment, first sensor 141 is two, and two first sensors 141 are symmetrical arranged.So both can be with The accuracy for the detection module that coincide is improved, while reduces cost and is advantageous to structure simplification.

Preferably, first sensor 141 includes the microswitch for being arranged on the bottom 131 of stapler 130.Can so have Effect adapts to the frequent switching in batch perfusion operation, ensures the service life of first sensor 141.

Wherein, the main function of the second detection unit 150 is whether the reagent 8 for detecting in perfusion container 9 reaches finger Fixed height；That is, when reagent 8 is not up to specified altitude assignment, the second detection unit 150 is not responding to；And when reagent 8 reaches finger When determining height, the second detection unit 150 responds.

In the present embodiment, the second detection unit 150 is fixed on intrusion pipe 110.It is, of course, understood that this reality It is not limited to be fixed on intrusion pipe 110 with the second new detection unit 150, can also be fixed on stapler 130.

With reference to referring to Fig. 5, it is preferable that the second detection unit 150 is liquid level sensor 151.So can be more efficiently Liquid reagent is detected, while improves detection accuracy.

It is highly preferred that the periphery of liquid level sensor 151 is additionally provided with sheath 152.Sheath 152 can also protect liquid level sensor 151 are not touched and are damaged.Sheath 152 is fixed on outside the tube wall of intrusion pipe 110.That is, liquid level sensor 151 passes through shield Set 152 is fixed on intrusion pipe 110.

In order to further optimize, the mouth of pipe of intrusion pipe 110 is less than the bottom of liquid level sensor 151.It is highly preferred that liquid level passes Sensor 151 is located at the middle part of the vertical direction of intrusion pipe 110.So after liquid level is higher than the mouth of pipe of intrusion pipe 110, the examination newly injected Agent is located at bottom, and original reagent is raised upwards, and such liquid level is steady all the time, effectively improves the precision of liquid level detection, So that reagent volumes are more accurate.

Wherein, control unit 160 couples with identical detection module, the second detection unit 150 and pouring valve 120.Control The main function of unit 160 processed is to control pouring valve based on the testing result of identical detection module and the second detection unit 150 120；That is, when identical detection module detect stapler 130 be enclosed on bottleneck 91 it is outer when, control unit 160 control perfusion Valve 120 is turned on, and reagent 8 is injected in perfusion container 9 from intrusion pipe 110；When the second detection unit 150 is detected in perfusion container When the surface of reagent reaches specified altitude assignment, control unit 160 controls pouring valve 120 to close, so as to which reagent 8 is trapped.

The course of work of the reagent filling device of the present embodiment is illustrated below.

First, reagent filling device 100 is installed in perfusion container 9, that is to say, that by the sleeve of stapler 130 in bottle On mouth 91.After stapler 130 and bottleneck 91 coincide, two microswitches are triggered, and control unit 160 controls pouring valve 120 open, and now start automatically to irrigate the row of perfusion container 9.When the height of reagent liquid level reaches specified altitude assignment, level sensing Device 151 detects that liquid level reaches specified altitude assignment, and control unit 160 controls pouring valve 120 to close.After completing to irrigate, only need Stapler 130 is pulled up, by the sleeve of stapler 130 on the bottleneck 91 of next perfusion container 9, that is, has started next filling Note the perfusion operation of container 9.

Mentioned reagent device for casting operates instead of human metering, using machine measure control, ensures that reagent volumes Accuracy, more ensure product capacity homogeneity；In addition, perfusion container need not be carried, reagent filling device only need to be pulled up, i.e., It can directly carry out next operation, it is simple and quick, while also avoid carrying adverse consequences caused by perfusion container.

Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, the scope that this specification is recorded all is considered to be.

Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed, But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
