Specific implementation mode
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant to the invention.
Embodiment
The present embodiment provides a kind of layerings to wash needle device, as shown in Figs. 1-5, including：Clean cylinder 101, the wash bowl
101 top of body is provided with inner cylinder 200, and upper cavity 20 is formed in inner cylinder 200, and cavity of resorption is formed on 101 bottom of cleaning cylinder
Body 10 is connected between upper cavity 20 and lower chamber 10 by access opening 30；
It is provided with to extend into upper cavity 20 on cleaning 101 side wall of cylinder and purifies water swivel 103, the inner cylinder 200
It is formed between outer wall and the cleaning cylinder 101 and overflows slot 203,203 bottom of spilling slot is provided with purifying aqueous waste solution discharge
Hole 202；
It is provided with several cleaning solution connectors 102 extending into lower chamber 10, cleaning solution connector on cleaning 101 side wall of cylinder
102 being circumferentially arranged along cleaning cylinder 101, while being continuously decreased along cleaning 101 axis direction of cylinder.
The cleaning cylinder 101 that needle device is washed in layering is divided into 3 layers from top to bottom：
1st layer is overflow layer, enters after purified water spilling and overflows slot, then is flowed into and given up by purifying aqueous waste solution tap 202
Liquid channel；
2nd layer is purified water cleaning layer, and purified water is injected from 200 bottom of inner cylinder, overflowed into after filling inner cylinder 200
Slot 203 is overflowed, 200 bottom surface of inner cylinder is lower 3-5mm than overflowing 203 bottom surface of slot, ensures that flow does not overflow and overflows outside slot 203
Portion；
3rd layer is cleaning solution cleaning layer, is circumferentially provided with 3-6 cleaning solution injection hole, is passed through cleaning solution and is carried out clearly to needle
It washes；
The purifying aqueous waste solution tap 202 for cleaning cylinder 101 is overflowing 203 bottom surface of slot, circumferentially at 2-4, aperture
It is identical or bigger as purified water injection aperture, ensure that the flow overflowed is more than the flow of input.
30 diameter of access opening is more bigger 0.5mm-1mm than needle diameter, after facilitating passing through for needle, needle to be inserted into access opening 30, due to
Annular space between needle and hole is smaller, and leak speed is much smaller than purified water injection rate, facilitates purifying sink trap；
The circumferentially Spiral distribution of cleaning solution connector mounting hole 211 on cylinder 101 is cleaned, cleaning solution connector 102 is along cleaning
It is continuously decreased, the coating part of needle sampling is all cleaned, while spiral knot with the height of 2-3mm on 101 axis direction of cylinder
Structure avoids interfering with each other between flow.
103 internal diameter 3-5mm of water swivel is purified, it is stable laminar condition that flow, which injects state,；
102 internal diameter 0.5-1mm of cleaning solution connector, streamflow regime inject by pressure for height, ensure cleaning performance；
102 installation site of cleaning solution connector is apart from needle outer wall 1-2mm；
Needle is placed on the 3rd layer of cleaning, the larger mode of pressure may be used and cleaned, cleaning performance is good.Needle is detached from clear
After washing lotion cleaning layer, cleaning solution stops projecting.Cleaning fluid pressure is big, and being mapped on 101 inside of cleaning cylinder can splash, due to the 1st
Layer has purified water with the 2nd layer, plays buffer action, makes it will not be from the access opening 30 of purifying aqueous waste solution tap 202 or needle
It splashes out；
4 102 Spiral distributions of cleaning solution connector, ensure that the circumference of needle can be washed to；It will not be mutual between flow
Interference；
203 can fill with purified water at inner cylinder 200 and spilling slot, more due to purified water density ratio phosphate solution density
Small, adsorption capacity smaller, needle point is not in hang liquid phenomenon when needle is extracted.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
