Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Embodiment
The present embodiment provides a kind of layerings to wash needle device, as shown in Figs. 1-5, comprising: cleaning cylinder 101, the wash bowl
It is provided with inner cylinder 200 at the top of body 101, forms upper cavity 20 in inner cylinder 200, 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；
Several cleaning solution connectors 102 extending into lower chamber 10, cleaning solution connector are provided on cleaning 101 side wall of cylinder
102 being circumferentially arranged along cleaning cylinder 101, while being gradually 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 useless by the purifying inflow of 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 3-5mm lower than overflowing 203 bottom surface of slot, guarantees that water 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 carries 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, guarantee that the flow overflowed is greater than the flow of input.
30 diameter of access opening is 0.5mm-1mm more bigger 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 gradually 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 water flow.
103 internal diameter 3-5mm of water swivel is purified, it is stable laminar condition that water flow, which injects state,；
102 internal diameter 0.5-1mm of cleaning solution connector, streamflow regime inject by pressure for height, guarantee cleaning effect；
102 installation site of cleaning solution connector is apart from needle outer wall 1-2mm；
Needle is placed on the 3rd layer of cleaning, can be cleaned using the biggish mode of pressure, cleaning effect is good.Needle is detached from clear
After washing lotion cleaning layer, cleaning solution stops projecting.Cleaning fluid pressure is big, and being mapped to inside cleaning cylinder 101 can splash, due to the 1st
Layer has purified water with the 2nd layer, plays buffer action, and so that it will not 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 water 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 is smaller, and needle point is not in hang liquid phenomenon when needle is extracted.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
