By reference to the accompanying drawings the present invention is described in further detail below by the specific embodiment.
Device for analyzing samples is by sampling, detects, and with this, obtains the data of sample composition.Sampling needle in the process of using, needs to clean after collecting sample, need to use the sampling needle cleaning device to clean.
Please refer to Fig. 1 to Fig. 2, waterfall type sampling needle cleaning device comprises sampling needle 1 and service sink 3, and sampling needle 1 is with inner wall washing liquid liquid outlet, and the cleaning fluid of this inner wall washing liquid liquid outlet outgoing is used for cleaning the sampling needle inwall; Service sink 3 is used for providing cleaning position, have on the sidewall that cleans groove and described cleaning groove and have an outer wall washing liquid liquid outlet at least, the cleaning fluid of this outer wall washing liquid liquid outlet outgoing is used for cleaning the sampling needle outer wall, drain in addition the discharge orifice of this inner wall washing liquid and this outer wall washing liquid on this service sink 3, wherein, sampling needle moves to cleaning position; Open inner wall washing liquid, clean the sampling needle inwall; Open outer wall washing liquid, clean the sampling needle outer wall; Sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from and cleans liquid level at least to sampling needle; The sampling needle translation goes out cleaning position.Because service sink 3 adopts the groove structure, sampling needle need not move vertically to cleaning position and clean, and has saved the testing time of device for analyzing samples, has improved the testing efficiency of device for analyzing samples; Due to sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from and cleans liquid level at least to sampling needle, has improved the measuring accuracy of device for analyzing samples.
on the basis of above-mentioned embodiment, sampling needle adopts hollow structure, hollow structure partly forms sampling needle inner wall washing liquid liquid outlet channel, on the needle point of sampling needle to inner wall washing liquid liquid outlet 2 should be arranged, service sink 3 is used for providing cleaning position, the middle part that service sink 3 makes progress a side is provided with the cleaning groove of an opening upwards, this cleaning groove is a sunk groove that forms on service sink, after the sampling needle application of sample directly horizontal movement to the cleaning of carrying out sampling needle in rinse bath, do not need the motion of vertical direction, save time, improved the test speed of device for analyzing samples.the first outer wall washing liquid liquid outlet 4a and the second outer wall washing liquid liquid outlet 4b are arranged on the sidewall of rinse bath, the bottom of rinse bath is provided with three cascading water passages, on rinse bath respectively to three cascading water holes should be arranged, sampling needle 1 is over against the first discharge orifice 5a of service sink 3, the inner wall washing liquid that is used for earial drainage sampling needle 1, the both sides of rinse bath also are respectively equipped with the second discharge orifice 5b and the 3rd discharge orifice 5c, the outer wall washing liquid that is used for earial drainage sampling needle 1, certainly, when middle cascading water hole flow is little, sampling needle 1 outer wall washing liquid also can both pass through the second discharge orifice 5b and the 3rd discharge orifice 5c earial drainage, also can carry out cascading water by the first cascading water hole 5a, equally, inner wall washing liquid also can both pass through the first discharge orifice 5a earial drainage, also can pass through the second earial drainage 5b and the 3rd discharge orifice 5c earial drainage.
Outer wall washing liquid is ejected on the outer wall of sampling needle 1 by the first outer wall washing liquid liquid outlet 4a and the second outer wall washing liquid outlet 4b of service sink 3, surround its sampling needle needle point outer wall and carry out outer wall washing, this moment, the distance of sampling needle needle point and service sink 3 bottoms was H, the height that sampling needle 1 needle point outer wall washing liquid covers is H1, and needle point outer wall washing liquid cover height H1 refers to the distance of peak on the sampling needle that from the sampling needle needle point to outer wall washing liquid, can be ejected into.Outer wall washing liquid liquid outlet can have one, also two or more can be arranged; The fluid injection direction of outer wall washing liquid can horizontal-jet, also can make progress or to declivity, spray; The shape of outer wall washing liquid liquid outlet can be circular hole, mounting hole, can be also square opening etc.Inner wall washing liquid liquid outlet only has one usually, and the shape of inner wall washing liquid liquid outlet is normally circular.
Because rinse bath is groove, so sampling needle 1 opens wide on the horizontal movement course bearing, so sampling needle 1 can directly clean after horizontally rotating cleaning position, need not to do vertical descending motion, saved the testing time of device for analyzing samples.Wherein, sampling needle moves to cleaning position; Open inner wall washing liquid, clean the sampling needle inwall; Open outer wall washing liquid, clean the sampling needle outer wall; Sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from and cleans liquid level at least to sampling needle, because sampling needle and/or service sink move in the opposite direction, this motion breaks away from the cleaning fluid liquid level at least to sampling needle, make sampling needle slowly break away from the cleaning liquid level, reduce extension liquid, improved the measuring accuracy of device for analyzing samples.It can be both that service sink maintains static that sampling needle and/or service sink move in the opposite direction, and sampling needle moves upward; Can also be that sampling needle maintains static, service sink moves downward; Can certainly be that sampling needle moves upward, service sink moves downward simultaneously,, as long as allow sampling needle slowly break away from cleaning fluid, just can reduce extension liquid, improves the measuring accuracy of device for analyzing samples.
Because sampling needle 1 horizontal movement course bearing opens wide, stop without solid wall surface, if sampling needle and/or service sink not to mutually away from the direction motion break away from liquid level at least to sampling needle, when the first outer wall washing liquid liquid outlet 4a and the second outer wall washing liquid outlet 4b closed, cleaning fluid was rapidly from the first cascading water hole 5a, the second cascading water hole 5b and the 3rd cascading water hole 5c cascading water.Obviously greater than the surface tension coefficient of air to water, so cleaning fluid is suspended on sampling needle 1 needle point outer wall surface under the effect of adsorption power due to the surface tension coefficient of 1 pair of cleaning fluid of sampling needle, causes sampling needle 1 to hang liquid measure more.If after sampling needle 1 cleans and completes, needle point is hung liquid, when next inhaling sample/reagent, the drop of suspension incorporates sample/reagent it is diluted, and particularly the sample application amount is less, and dilution phenomenon shows more seriously, causes test result inaccurate; After each test is cleaned and completed in addition, the extension liquid measure is different, has certain randomness, thereby different to the dilute strength of sample/reagent, causes test result repeatability variation.In a word, the extension liquid of sampling needle 1 needle point can affect accuracy and the repeatability of instrument test result, thereby affects measuring accuracy.So present embodiment adopt sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from and cleans liquid level at least to sampling needle, makes sampling needle slowly break away from cleaning fluid, has reduced extension liquid, has improved the measuring accuracy of device for analyzing samples.

Please refer to as Fig. 3, in one embodiment, sampling needle moves to cleaning position, opens inner wall washing liquid, cleans the sampling needle inwall; Open outer wall washing liquid, clean the sampling needle outer wall; Sampling needle 1 and/or service sink 3 to mutually away from the direction motion, this motion breaks away from and cleans liquid level at least to sampling needle 1, sampling needle 1 translation goes out cleaning position.Break away from and clean liquid level at least to sampling needle because sampling needle and/or service sink move in the opposite direction, make sampling needle slowly break away from the cleaning liquid level, improved the measuring accuracy of device for analyzing samples.
On the basis of above-mentioned embodiment, the mode that sampling needle moves to cleaning position had both comprised rectilinear translation, also comprised curvilinear translation; Open inner wall washing liquid, inner wall washing liquid carries out inner wall washing by the liquid that inner wall washing liquid liquid outlet penetrates; Open outer wall washing liquid, outer wall washing liquid carries out outer wall washing by the liquid that outer wall washing liquid liquid outlet penetrates; Sampling needle and/or service sink to mutually away from the method for direction motion, both comprised that service sink maintained static, sampling needle moves upward, and comprises that also sampling needle maintains static, service sink moves downward, and also comprises that sampling needle moves upward, service sink moves downward simultaneously.When sampling needle carries out inwall, outer wall washing, can carry out at once sampling needle and/or service sink to mutually away from the step of direction motion, also can carry out again after a period of time at sampling needle, outer wall washing sampling needle and/or service sink to mutually away from the step of direction motion.Inner wall washing liquid and the outer wall washing liquid of sampling needle both can be opened simultaneously, also can successively open, and both can first open inner wall washing liquid, first cleaned the sampling needle inwall, also can first open outer wall washing liquid, first cleaned the sampling needle outer wall.After sampling needle moves to cleaning position, can open at once inner wall washing liquid and/or outer wall washing liquid, open again inner wall washing liquid and/or outer wall washing liquid after also can waiting a period of time.Break away from and clean liquid level at least to sampling needle because sampling needle and/or service sink move in the opposite direction, make sampling needle slowly break away from the cleaning liquid level, improved the measuring accuracy of device for analyzing samples.
In embodiment more specifically, sampling needle and/or service sink to mutually away from the direction motion refer to maintain static with service sink, sampling needle moves upward, needle point outer wall washing height is H1, when cleaning is near completion, when cleaning fluid continued sampling needle 1 is carried out outer wall washing, sampling needle 1, moved both vertically and highly is H2 from position 1b vertical lifting to position 1c with certain speed; Last sampling needle 1 carries out suction sample/reagent action from position 1c horizontal movement to position 1d.Clean liquid level because sampling needle moves upward until sampling needle breaks away from, the speed of reasonable disposition sampling needle 1 vertical ascending motion, can be reduced to bottom line with outer wall hanging liquid measure simultaneously; Make cleaning fluid slowly separate with sampling needle 1, obviously greater than the surface tension of 1 pair of cleaning fluid of sampling needle, cleaning fluid leaves sampling needle 1 outer wall surface under the effect of molecular force due to the intermolecular active force of cleaning fluid, thereby reduce the sampling needle needle point, hangs liquid measure.
On the basis of above-mentioned embodiment, also comprise the step of closing outer wall washing liquid: when sampling needle is transported to its height greater than H1, close sampling needle outer wall washing liquid.Above-mentioned steps makes sampling needle naturally break away from outer wall washing liquid, makes sampling needle slowly break away from outer wall washing liquid, has reduced extension liquid, has improved the precision of pattern detection.After sampling needle breaks away from outer wall washing liquid, can close outer wall washing liquid.After sampling needle breaks away from outer wall washing liquid, more early close outer wall washing liquid and more save cleaning fluid.
On the basis of above-mentioned embodiment, also comprise the step of closing inner wall washing liquid, before the sampling needle translation goes out cleaning position, also comprise the step of closing inner wall washing liquid.Inner wall washing liquid is more early closed and is more saved cleaning fluid, and the outer wall washing liquid opening time more washes cleaner in Changqing.Can consider above-mentioned factor and determine the shut-in time of inner wall washing liquid.
In the above-described embodiment, the distance H of sampling needle needle point and service sink bottom is as long as meet the requirement that can carry out horizontal movement, and when sampling needle 1 is cleaned, positioning accuracy request is low.
On the basis of above-mentioned embodiment, please refer to Fig. 4, the outer wall washing of sampling needle 1, inner wall washing, move both vertically and the sequential relationship of horizontal movement, be defined as follows time parameter:
T1---sampling needle 1 cleans while being near completion, and sampling needle 1 starts to do vertical ascending motion, moves to and just breaks away from the time of cleaning liquid level (vertical range of sampling needle 1 motion is H1);
T2---sampling needle 1 just break away from clean liquid level to the time that sampling needle 1 is completed ascending motion (vertical range that sampling needle 1 moves is H2) be T2;
The total time that T---sampling needle 1 moves both vertically, T=T1+T2;
T3---sampling needle 1 is completed vertical ascending motion to the time that starts horizontal movement;
T4---close outer wall washing liquid and complete the time of vertical ascending motion to sampling needle 1;
T5---close the time of inner wall washing liquid to sampling needle 1 beginning horizontal movement;
Each time meets following relation:
After T2＞0, sampling needle 1 rise to and break away from the cleaning liquid level, in a preferred embodiment, sampling needle continues to rise until with the outer wall washing liquid level, maintain a certain distance, reduce outer wall washing and close rear needle point extension liquid, hang liquid for reducing needle point simultaneously, T2 tries one's best little of to save time.
T3 〉=0, ability horizontal movement after sampling needle 1 has moved both vertically, T3 tries one's best little of to save time.
0≤T4≤T2, after being closed in sampling needle 1 and breaking away from and clean liquid level of outer wall washing liquid, before sampling needle 1 is completed vertical ascending motion, sampling needle 1 break away from clean liquid level after cleaning fluid can not clean to the outer wall of sampling needle 1, therefore can close immediately outer wall washing liquid, to save cleaning fluid.
0≤T5≤T+T3, inner wall washing liquid are closed in after sampling needle 1 starts to rise, before sampling needle 1 horizontal movement.The time of inner wall washing liquid is longer, and that cleans is cleaner, and simultaneously, the time of cleaning is shorter, more saves cleaning fluid.
Outer wall washing liquid must after sampling needle breaks away from the cleaning liquid level, be closed before the sampling needle horizontal movement; Inner wall washing liquid is after the sampling needle ascending motion, and any moment before the sampling needle horizontal movement can close.
As mistake! Do not find Reference source.Be depicted as preferred embodiment a kind ofly, work as T3=0, T4=T2 during T5=0, closes outer wall washing liquid when sampling needle breaks away from outer wall washing liquid liquid level at once, and outer wall washing is economized on water most; Just close inner wall washing liquid in sampling needle moves both vertically process until before the sampling needle horizontal movement, the inner wall washing time is the longest; Carry out immediately horizontal movement after sampling needle moves both vertically, save time.In rise and fall time, solve the outer wall hanging liquid of sampling needle 1 problem when saving sampling needle 1 cleaning, improve the measuring accuracy of instrument; Service sink 3 is simple in structure, and is low to the cleaning requirement precision.The first cascading water hole 5a diameter can more greatly, reduce while occurring cleaning and spatter the liquid phenomenon; Through actual test, this cleaning way can better solve sampling needle 1 and clean the liquid problem of hanging, visually observe without obvious drop and be suspended on sampling needle 1 needle point outer wall, it is also quite little that quantitative test is hung liquid measure, and the accuracy of device for analyzing samples test result and repeatability also better.
In another embodiment, sampling needle and/or service sink to mutually away from the direction motion refer to that sampling needle maintains static, service sink moves downward.Sampling needle cleans while being near completion, and when cleaning fluid continued sampling needle 1 is carried out outer wall washing, sampling needle 1 was motionless, and service sink is done vertical descending motion with certain speed under the drive of motor, until sampling needle 1 breaks away from fully, cleans liquid level; Make sampling needle also slowly break away from and clean liquid level, can reduce equally the sampling needle needle point and hang liquid.In a word,, as long as make sampling needle slowly break away from cleaning fluid, can reach the effect that reduces sampling needle needle point extension liquid.
The present invention also provides a kind of device for analyzing samples, comprises above-mentioned sampling needle cleaning device.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
