A kind of water flowing filtering type sampling craft based on above-mentioned apparatus, includes the following steps：
A1, feed liquor needle 501 are logical by the feed liquor at the first driven wheel 423,425 center of first connecting rod 424 and first shaft coupling
Hole 429 is inserted into the vertical hollow hole 338 at 309 center of hollow stem, detected sample solution is passed through on hollow stem 309
Fluid hole 323 is sent in the first chamber 325 of interior cup body 320.
A2, detected sample solution carry out first time filtering by the first filter screen 318 on 320 wall of cup of interior cup body, make
Impurity more than sample particle size is blocked in the first chamber 325, and filtered detected sample solution then enters for the first time
To the second chamber 326；First motor 412 starts simultaneously, drives the feed liquor bar in the first chamber 325, the swingle in the second chamber 326
328 rotations, are stirred the detected sample solution in the first chamber 325 and the second chamber 326；It is filtered for the first time to be detected
Sample solution carries out second by the second filter screen 335 on arc panel again and filters, and makes the impurity less than sample particle size
Third chamber 327 is entered, goes out liquid needle and is inserted into third chamber 327 by the 4th aperture 306 on cup lid 302, will be filtered twice
The sample solution for entering third chamber 327 afterwards is extracted out.
A3, sampling probe or other sampling tools are inserted into the second chamber 326, extraction stays in real in the second chamber 326
Useful detected sample solution is detected analysis.
Since the mesh aperture of the first filter screen 318 on 320 wall of cup of interior cup body of the present invention is molten more than detected sample
The mesh aperture of sample particle size in liquid, the second filter screen 335 on the arc panel is less than in detected sample solution
Sample particle size.Enter the first chamber 325 when detected sample solution is continuous, then is constantly extracted twice from third chamber 327
When filtered discard solution, other impurity more than sample particle size are just blocked in the first chamber 325, and are less than sample
The impurity of particle size is just entered by filtering twice in third chamber 327, the detected sample that really can be used for testing and analyzing
Sample particle in solution has been left in the second chamber 326, and sampling probe is inserted into the second chamber 326 and extracts detected sample solution
It is detected analysis, is filtered and is isolated by impurity, the detected sample solution of extraction is in microexamination, due to not having impurity
The interference of particle, Electronic Speculum, which is taken pictures and is analyzed, to be more clear, count will be more accurate, testing result will it is more true,
It is more accurate.Disclosure is particularly well suited to the sample detectings of excreta, by the mesh hole of the first filter screen 318 on interior cup body 320
Diameter is designed to the worm's ovum particle size being more than in excreta, is designed to the mesh aperture of the second filter screen 335 on arc panel
Less than the worm's ovum particle size in excreta, then extracted out from the injection of the first chamber 325, from third chamber 327, then actually useful
Worm's ovum in the excreta that can be used to test and analyze just is left in the second chamber 326, and the impurity particle of other Interference Detections is just
It is extracted out in the first chamber 325 or from third chamber 327 by filtering cleaning barrier, makes the Electronic Speculum detection and analysis of excreta more
Clearly, counting is more accurate, detection is more accurate.
Structure of the invention is ingenious in design, realizes that feed liquor, stirring, filtering, cleaning removal of impurities, to go out liquid etc. a variety of with an equipment
Function, solve existing sampling apparatus have a single function, detected sample solution be easy by impurity interference, take pictures it is unintelligible, count
Inaccurate problem.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example.It should be pointed out that for those skilled in the art, without departing from the principles of the present invention several change
Into and retouching, also should be regarded as protection scope of the present invention.The available prior art of each component part being not known in the present embodiment
It is realized.
