Fig. 4 is the structural schematic diagram of one embodiment of sampling bottle in excrement quantitative sampling device of the present invention；Fig. 5 is excrement of the present invention
Just in quantitative sampling device one embodiment of Double layer bottle cap structural schematic diagram.On the basis of the various embodiments described above, the present embodiment
In, as shown in Figure 4 and Figure 5, sampler of the invention further include: sampling bottle 4 and Double layer bottle cap 5；The Double layer bottle cap 5 wraps
It includes: internal layer bottle cap 51 and outer layer bottle cap 52；The internal layer bottle cap 51 is threaded in the bottle mouth position of the sampling bottle 4, and it is pushed up
Portion is equipped with liquid outlet, and the detachable set of the outer layer bottle cap 52 is outside the internal layer bottle cap 51, to block the liquid outlet.
Specifically, it after the completion of sampling head 1 samples, by being unloaded on Sampled Hand Grip 2, is put into sampling bottle 4 and collects sample, use
Internal layer bottle cap 51 is tightened in bottle mouth position, then 52 sets of outer layer bottle cap can save sample outside internal layer bottle cap 51.When need
When taking out sample, outer layer bottle cap 52 is removed, sample is poured out by the liquid outlet of internal layer bottle cap 51.It, can in sampling process
Quantitative sampling is carried out using multiple sampling heads 1, and sampling needs sample to be put into sampling bottle 4 after the completion to be diluted, herein mistake
It needs to unload sampling head 1 in journey and be put into sampling bottle 4, and the process unloaded only needs for multiple sampling heads 1 to be respectively placed in
The bottle mouth position of sampling bottle 4, applying external force to Sampled Hand Grip 2 makes sampling head 1 by removing on Sampled Hand Grip 2, easy to operate, fast
It is prompt.Further, since sampling quantity can quantitatively obtain, before sampling head 1 is put into sampling bottle 4, can shift to an earlier date in sampling bottle 4 be packed into
Sampling quantity is in the sample diluting liquid for fixing multiple volume, it can be achieved that the quantitative dilution of sample.
Further, sampling bottle 4 can be used elastic material and be made, such as flexible plastic is made, and can be taken out by squeezing body
Sample.In addition, also one layer of filter membrane 511, the preferred 100-500 in the aperture of filter membrane 511 can be arranged in the bottom of internal layer bottle cap 51
Mesh, when toppling over or squeezing sampling bottle 4 and be sampled, the filter membrane 511 in internal layer bottle cap 51 plays the role of filtering, may filter that
The impurity and granular residue in sample suspension after falling dilution, avoids the solid impurity in sample from impacting testing result.
And it is the breakage for preventing filter membrane 511, also one ring shape can be set in the lower section that the bottom of internal layer bottle cap 51 is located at filter membrane 511
Gasket.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
