It sets, air sampling is not easy to carry out.Furthermore bottleneck is sealed using calutron, structure is complicated, consuming energy, and cannot have both
The samples such as air, liquid acquire function.Meanwhile after existing apparatus is acquired, late-run sample grouping also needs further operating,
Waste equipment and manpower.
In conclusion problem of the existing technology is: existing sampling apparatus need to be opened manually in sampling, sample
It is covered manually after finishing.Experimenter itself can carry the entrance of the microorganism in outside air in this way, influence experimental result, and not
If negative pressure device, air sampling is not easy to carry out.Furthermore bottleneck is sealed using calutron, structure is complicated, consuming energy, and
The samples acquisition function such as air, liquid cannot be had both.Meanwhile after existing apparatus is acquired, late-run sample grouping need to also be into
Single stepping wastes equipment and manpower.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of sample acquisition environmental control system.
The utility model is realized in this way a kind of sample acquires environmental control system, the sample acquires environmental control system
It is provided with
Collecting cassette；

Handle on box cover；It is provided with negative pressure gasbag below handle, negative pressure gasbag is connected to the first sebific duct and the second sebific duct；First
Pipe clamp is accompanied on sebific duct and the second sebific duct；Sampling pipe is mounted on collecting cassette bottom, and sampling pipe is equipped with check valve；Replaceability
Box set is socketed in inside collecting cassette by fixed attachment strap, and fluting has acquisition interface tube below replaceability box set；Acquire interface tube
It is connected to sampling pipe snapping；Sample grouping pipe is welded on the right side of collecting cassette.
Further, the pressure handle connects the box cover by riveting method, is cased with torsional spring on the pivot.Box cover is in torsional spring
Under the action of closely cover on the collecting cassette.
Further, the acquisition box mouth is equipped with gasket, and gasket is bonded on the collecting cassette.
Further, the handle appearance is equipped with anti-skid chequer.
Further, switch rotary is connected on sample grouping pipe.
The advantages of the utility model and good effect are as follows:
The utility model pressing pressure handle can be such that the microorganism near acquisition port enters in collecting cassette, easy to operate, avoid
Experimenter directly touches acquisition box cover, influences collection result.It is suitable for fluid samples, the structures such as acquisition water sample simultaneously simply may be used
It leans on, sample whole process is in enclosure space, avoids the leakage of sample and contacts bring cross contamination with the external world, ensure that and adopt
The reliability and accuracy of all product.And the setting of replaceability box set so that used it is primary after next time use not by
Substance in last collecting cassette influences, and sample is avoided to pollute, while the setting of pipe is grouped by sample, is conducive to sample acquisition
Later period grouping afterwards.
The utility model is easy to operate, avoids sample leakage and sample pollution, reduces experimental error, guarantee the reliable of sample
Property and accuracy.
Detailed description of the invention

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing 1 and attached drawing 2.
As depicted in figs. 1 and 2, sample acquisition environmental control system provided by the embodiment of the utility model is provided with collecting cassette
1, box cover 2, pivot 3, pressure handle 4, handle 5, negative pressure gasbag 6, the first sebific duct 7, pipe clamp 8, the second sebific duct 9, check valve 10, sampling pipe
11, replaceability box set 12, sample grouping pipe 13, switch 14, fixed attachment strap 15, acquisition interface tube 16.
It is the box cover 2 above the collecting cassette 1,2 left side of box cover is connect with pivot 3, and box cover 2 crosses pivot 3 and pressure handle 4
Connection, 4 lower part of pressure handle are handle 5, are connected below handle 5 for negative pressure gasbag 6, negative pressure gasbag 6 and the first sebific duct 7 and the second sebific duct 9
Logical, pipe clamp 8 is clipped on the first sebific duct 7 and the second sebific duct 9, and the setting of sampling pipe 11 is equipped with only in 1 bottom of collecting cassette, sampling pipe 11
