Abstract
The utility model discloses a vacuum test tube device for eating quality control surveys, locate including U -shaped clear glass pipe, sealed inserting the frustum rubber buffer of the mouth of pipe department of U -shaped clear glass pipe, run through insert locate the frustum rubber buffer and respectively with the cavity of U -shaped clear glass pipe link up the evacuating device of setting and inhales detection device certainly, the intraductal detect reagent that is provided with of U -shaped clear glass. The setting of frustum rubber buffer along with the increase of top pressure, can form effective sealedly with the mouth of pipe of U -shaped clear glass pipe, evacuating device and from the setting of inhaling detection device can make the outside food solution that is detected take place the reaction through inhaling the automatic U -shaped clear glass pipe that flows in of detection device certainly with detect reagent, and then effectively avoids detect reagent by the oxidation, avoids the liquid of postdetection to abandon the environmental pollution who brings at will.
Description
Technical field
This utility model relates to technical field of food detection, particularly relates to a kind of vacuum for food inspection and tries
Pipe device.
Background technology
In food in the market, the detection mode of illegal additive or food additive is generally with Extraction and enrichment
Or after concentrating, then detect with electronics capture, hydrogen flame, ultraviolet or other detector after chromatographic isolation,
This detector detection method is accurate, precision is high, detection limit is low, but detection time length, front comparatively speaking
Process complexity, instrument and equipment requires that high, operation easier greatly, thus is typically only capable to be applied to the inspection of various laboratory
Survey.Along with people's enhancing to Consciousness of food security, those free of contamination green health food are increasingly subject to
The welcome of people.Substantial amounts of sxemiquantitative method for quick the most qualitatively, this detection side it is badly in need of on market
Method sample typically needs not move through the pre-treatment of complexity, it is only necessary to a few minutes to more than ten minutes just can go out detection knot
Really, which kind of model the content whether containing a certain amount of object or object in preliminary judgement sample is generally in
Enclose.Sxemiquantitative or qualitative food safety quick detection reagent the most on the market are typically liquid reagent, room temperature
Normal pressure is stored, and uses and is initially charged a certain amount of testing sample extracting solution in sample cell, then drip during use
Some of detectable, mixing, develops the color after certain time, compares with standard color comparison card and carry out result of determination.
This method because detectable be in reagent bottle at normal temperatures and pressures easily oxidation and make the shelf-life the longest,
And the use that breaks a seal re-uses easy leakage the most afterwards and causes security incident；Furthermore, after the detection of this detection pipe
Liquid usually contains chemical pollutant, recycling difficulty, arbitrarily abandons and can cause environmental pollution.
Utility model content
The purpose of this utility model is to provide a kind of convenient to operation, detectable unsuitable oxidized and
The vacuum test tube device of environment should not be polluted.
For reaching this purpose, this utility model by the following technical solutions:
A kind of vacuum test tube device for food inspection, this vacuum test tube device include U-shaped transparent glass tube,
Seal and be inserted in frustum rubber stopper at the mouth of pipe of described U-shaped transparent glass tube, run through and be inserted in frustum rubber
Plug and respectively with vacuum extractor and the self-priming detection device of the through setting of cavity of described U-shaped transparent glass tube,
It is provided with detectable in described U-shaped transparent glass tube.
Wherein, described vacuum extractor include running through be inserted in described frustum rubber stopper evacuation syringe needle and
Air pump that the exhaust tube of the described through connection of evacuation syringe needle is connected with described exhaust tube and being arranged at
The first pressure regulator valve in the middle part of described exhaust tube.
Wherein, described self-priming detection device include running through be inserted in described frustum rubber stopper sampling syringe needle and
The described through connection of sampling syringe needle sampling trachea be connected with described sampling trachea food solvent bottle, with
And it is arranged at the second pressure regulator valve in the middle part of described sampling trachea.
Wherein, the vacuum in described U-shaped transparent glass tube is less than 100Kpa more than 85Kpa.
Wherein, the degree of depth in described frustum rubber stopper inserts described U-shaped transparent glass tube is more than 10mm.
The beneficial effects of the utility model: this utility model vacuum test tube device include U-shaped transparent glass tube,
Seal and be inserted in frustum rubber stopper at the mouth of pipe of described U-shaped transparent glass tube, run through and be inserted in frustum rubber
Plug and respectively with vacuum extractor and the self-priming detection device of the through setting of cavity of described U-shaped transparent glass tube,
It is provided with detectable in described U-shaped transparent glass tube.The setting of frustum rubber stopper, along with top pressure
Increase, it is possible to form effectively sealing with the mouth of pipe of U-shaped transparent glass tube；Vacuum extractor and self-priming detection dress
The setting put, it is possible to make outside detected food solution automatically flow into U-shaped by self-priming detection device transparent
Glass tubing reacts with detectable, and then it is oxidized to be prevented effectively from detectable, it is to avoid the liquid after detection
Body arbitrarily abandons the environmental pollution brought.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vacuum test tube device for food inspection of this utility model.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As it is shown in figure 1, the vacuum test tube device in the present embodiment includes that U-shaped transparent glass tube 1, sealing plug
Frustum rubber stopper 2 at the mouth of pipe of described U-shaped transparent glass tube 1, run through be inserted in frustum rubber stopper 2 and
Respectively with vacuum extractor and the self-priming detection device of the through setting of cavity of described U-shaped transparent glass tube 1,
Being provided with detectable in described U-shaped transparent glass tube 1, described vacuum extractor includes running through and is inserted in institute
State the evacuation syringe needle 31 of frustum rubber stopper 2 through with described evacuation syringe needle 31 be connected exhaust tube 32,
The air pump 33 that is connected with described exhaust tube 32 and be arranged at the first pressure regulation in the middle part of described exhaust tube 32
Valve 34, described self-priming detection device include running through be inserted in described frustum rubber stopper 2 sampling syringe needle 41 and
The sampling trachea 42 of the described through connection of sampling syringe needle 41 is molten with the food that described sampling trachea 42 is connected
Agent bottle 43 and be arranged at the second pressure regulator valve 44 in the middle part of described sampling trachea 42, the transparent glass of described U-shaped
