Problems solved by technology

[0002] When using a micro-dropper, it is necessary to make the liquid drip evenly along the micro-droplet, so it is necessary to conduct a variable test on the micro-dropper to ensure the dripping effect of the micro-droplet, so it is necessary to adjust the length and cross-sectional area of ​​the micro-dropper and other variables However, when testing, when the liquid is pumped through the water pump, the pump usually generates pulses when the liquid is pumped and transported, so it will affect the reliability of the test after it enters the microdrop tube

Embodiment approach 1

[0028] Adjust the position of the main connecting plate 3 by adjusting the stretching amount of the main telescopic rod 17 to stretch the connecting pad 5, so adjust the stretching length and the internal space of the connecting pad 5 to store the liquid. When the connecting pad 5 is stretched, the microdrop port 6 is stretched to deform it, thereby changing the diameter of the microdrop port 6 for testing, making the test more flexible;

[0029] And when adjusting the cross-sectional area of ​​the connection pad 5 for testing, after the main connection plate 3 stretches the connection pad 5 to a suitable position, the connection pad 5 pulls the support bar 19 to perform synchronous stretching, and respectively pulls the auxiliary telescopic rod 20 along the slideway 18 slides to adapt to the tension variable of the connection pad 5, and when it is necessary to adjust the cross-sectional area of ​​the connection pad 5, the support bar 19 is pulled upward or squeezed downward by...

Embodiment approach 2

[0031] By rotating the main screw 21 and threadingly engaging with the installation shell 1, the position is moved, thereby pulling the main connecting plate 3 to move the position, and pulling and stretching the connecting pad 5, thus changing the stretching length of the connecting pad 5 and its inner body The liquid is stored in space, and the droplet port 6 is stretched to deform it, thereby changing the caliber of the droplet port 6 to perform the droplet test;

[0032] When adjusting the cross-sectional area of ​​the connection pad 5 for testing, after the main screw 21 stretches the connection pad 5 to a suitable position, the connection pad 5 pulls the support bar 19 to perform synchronous stretching, thereby respectively pulling the auxiliary screw 24 to drive the slider 23 Move the position along the adjustment port 22 to adapt to the stretching variable of the connection pad 5, and adjust the cross-sectional area of ​​the connection pad 5 to adjust the threaded engag...

Abstract

The invention discloses a micro dropper testing device, and relates to the technical field of micro drop testing devices. The device comprises a mounting shell with an opening in the side wall; a plurality of sliding rails are mounted on the inner side wall of the mounting shell; the connecting pad is connected with the main connecting plate and the auxiliary connecting plate to form a closed space. A transverse position adjusting mechanism is mounted on the side wall of the main connecting plate; a micro-drop opening is formed in the outer side wall of the connecting pad in the length direction; a longitudinal position adjusting mechanism is mounted on the outer side wall of the connecting pad; a partition plate is hermetically mounted in the connecting shell; and the stable cavities are internally communicated with circulating pipes respectively. The device has the advantages that when the water pump pumps and transports liquid, the piston in the connecting shell moves to change the space so as to store the liquid, pulsation generated by the water pump during liquid transportation is eliminated, liquid transportation is more stable, testing is more reliable, the connecting pad is stretched during testing, and the length of the connecting pad is adjusted. And the side wall is stretched and extruded to adjust the sectional area, so that the test is variable, and the use is more flexible and reliable.

Description

technical field [0001] The invention relates to the technical field of droplet testing devices. Background technique [0002] When using a micro-dropper, it is necessary to make the liquid drip evenly along the micro-droplet, so it is necessary to conduct a variable test on the micro-dropper to ensure the dripping effect of the micro-droplet, so it is necessary to adjust the length and cross-sectional area of ​​the micro-dropper and other variables And carry out the test, and when carrying out the test, when the liquid is drawn by the water pump, the water pump usually makes it generate a pulse when the liquid is drawn and transported, so it will affect the reliability of the test after it enters the microdrop tube. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a micro-dropper testing device for the above-mentioned technical deficiencies. When the water pump is pumping and transporting the liquid, the movement...
