the tee fitting 110 includes a first end, a second end, and a third end; the guide tube 120, the injector 130 and the liquid outlet tube 140 are respectively connected with the first end part, the second end part and the third end part; the first check valve 150 is disposed at a connection position of the draft tube 120 and the first end, and the first check valve 150 is used for one-way conduction from the draft tube 120 to the first end; the second check valve 160 is disposed at a connection position of the liquid outlet tube 140 and the third end portion, and the second check valve 160 is used for unidirectional conduction from the third end portion to the liquid outlet tube 140;
wherein, the end of the draft tube 120 far away from the three-way joint 110 is used for extending into the liquid level below the enzyme liquid barrel 10, and the injector 130 is used for extracting the enzyme liquid in the enzyme liquid barrel 10 and for pushing the extracted enzyme liquid back to the liquid outlet tube 140.
The working principle of the enzyme solution suction device 100 is as follows:
referring to fig. 1, the enzyme solution pumping device 100 includes a three-way joint 110, a flow guide tube 120, an injector 130, a liquid outlet tube 140, a first one-way valve 150 and a second one-way valve 160; the tee fitting 110 includes a first end, a second end, and a third end; the guide tube 120, the injector 130 and the liquid outlet tube 140 are respectively connected with the first end part, the second end part and the third end part; the first check valve 150 is disposed at a connection position of the draft tube 120 and the first end, and the first check valve 150 is used for one-way conduction from the draft tube 120 to the first end; the second check valve 160 is disposed at a connection position of the liquid outlet tube 140 and the third end portion, and the second check valve 160 is used for unidirectional conduction from the third end portion to the liquid outlet tube 140; wherein, the end of the draft tube 120 far away from the three-way joint 110 is used for extending into the liquid level below the enzyme liquid barrel 10, and the injector 130 is used for extracting the enzyme liquid in the enzyme liquid barrel 10 and for pushing the extracted enzyme liquid back to the liquid outlet tube 140.
Therefore, in the process of using the enzyme solution pumping device 100, the first check valve 150 is in one-way communication from the direction of the guide tube 120 to the first end, and the second check valve 160 is in one-way communication from the third end to the liquid outlet tube 140, so that when the injector 130 starts to pump the enzyme solution, the enzyme solution in the enzyme solution barrel 10 can be pumped into the injector 130 through the guide tube 120, the first end and the second end; similarly, when the injector 130 starts to push back, the enzyme solution can be pushed into the liquid outlet pipe 140 from the injector 130, the second end part and the third end part, and the liquid outlet pipe 140 can be led to the water tank, so that the enzyme solution is mixed with the cleaning water in the water tank to prepare the cleaning solution; thus, in this way, the amount of enzyme solution output from the liquid outlet pipe 140 can be measured by the injector 130, so that the accuracy of enzyme solution proportioning can be improved, and the waste of enzyme solution can be reduced.
In summary, in the process of using the enzyme solution pumping device 100, since the flow guide tube 120 and the liquid outlet tube 140 are in the one-way conduction state, the output of the enzyme solution can be completed through the extraction and reverse pushing operations of the injector 130 in this way, and in the process of outputting the enzyme solution, the amount of the pushed enzyme solution can be measured through the measuring scale lines of the injector 130, so that the amount of the enzyme solution output by the liquid outlet tube 140 can be controlled through the pushing action of the injector 130 in the process of proportioning the enzyme solution, and such a solution proportioning way is simple and convenient, and the waste of the enzyme solution can be reduced while the accuracy of proportioning of the enzyme solution is improved. Before the enzyme solution is drawn and pushed by the syringe 130, the enzyme solution suction device 100 needs to be evacuated, that is, air in the enzyme solution suction device 100 needs to be discharged, so that the accuracy of enzyme solution output is not affected by air in the enzyme solution suction device 100 when the enzyme solution is output.
Further, referring to fig. 1, in the present embodiment, in order to simplify the operation of the injector 130, in the present embodiment, the enzyme solution suction device 100 further includes a suction tube 170, and two ends of the suction tube 170 are respectively communicated with the injector 130 and the second end. When the suction pipe 170, the flow pipe 120, and the liquid outlet pipe 140 are disposed, the suction pipe 170, the flow pipe 120, and the liquid outlet pipe 140 may be stainless steel pipes having an inner diameter of 0.8 mm. And the outer diameters of the first check valve 150 and the second check valve 160 may be 0.88 mm.
Further, in this embodiment, the enzyme solution pumping device 100 further includes a connecting cover 180, the connecting cover 180 is used for connecting with the enzyme solution barrel 10, and the connecting cover 180 is provided with a mounting hole; the guide pipe 120 is used for matching with the mounting hole and extending into the enzyme liquid barrel 10.
Accordingly, in order to maintain the state in which the flow tube 120 protrudes below the liquid level in the enzyme solution tank 10, the connection cap 180 is provided, and the connection cap 180 is connected to the enzyme solution tank 10 and the connection cap 180 is connected to the flow tube 120, thereby maintaining the mounting state of the flow tube 120 and the enzyme solution tank 10. It should be noted that, because the volume or size of the enzyme liquid barrel 10 changes under different use conditions, in order to adapt to different enzyme liquid barrels 10, the connecting cover 180 is used for being screwed with the barrel mouth of the enzyme liquid barrel 10, that is, the connecting cover 180 is detachably connected with the enzyme liquid barrel 10, so that the installation requirements of different enzyme liquid barrels 10 can be adapted by replacing connecting covers 180 with different sizes, and the application range of the enzyme liquid suction device 100 can be expanded.
Further, referring to fig. 1, in the present embodiment, the enzyme solution pumping device 100 further includes a housing 190, and the housing 190 is used for maintaining the positions of the three-way joint 110, the flow guide tube 120, the liquid outlet tube 140 and the injector 130 relative to the enzyme solution barrel 10; specifically, since the connecting cover 180 is connected to the enzyme solution tank 10, the connecting cover 180 includes a first part 181 and a second part 182 connected to the first part 181, the first part 181 is connected to the enzyme solution tank 10, and the second part 182 is connected to the housing 190; the three-way joint 110 and the fluid guide tube 120 are accommodated in the housing 190, the injector 130 is located outside the housing 190, and the housing 190 is provided with a through hole for the fluid outlet tube 140 and the suction tube 170 to pass through. Therefore, the three-way joint 110, the flow guide pipe 120, the suction pipe 170, the liquid outlet pipe 140 and the injector 130 can be supported in such a way, so that the situation that the position of the enzyme liquid suction device 100 is changed to influence the operation or influence the liquid outlet position of the liquid outlet pipe 140 in the using process is prevented, and the normal liquid distribution can be ensured.
As is apparent from the above description, since the enzyme solution tank 10 has different dimensional parameters under different conditions, the connection cover 180 can be easily replaced by providing the first part 181 with an internal thread for screwing the enzyme solution tank 10 and the second part 182 with an external thread for screwing the housing 190, that is, by detachably connecting the first part 181 and the second part 182 to the enzyme solution tank 10 and the housing 190, respectively, so as to replace the connection cover 180.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
