Preferably, the gas passage and the sampling channel are oppositely disposed at the both ends of the ontology.This setting Optimize the gas pressure distribution inside container so that the pressure difference between sampling channel and gas passage is sufficiently large, is conducive to the stream of sample Go out and stops.
Preferably, the container further includes a grinder, the grinder is located at the center of the container.Grinder can be with It is common blender, can also be ultrasonic grinder etc..
Preferably, the container further includes an isolation filter bowl, the isolation filter bowl is located at the outside of the grinder.By This, the bulky grain sample of crushing is blocked in isolation filter bowl, ensure that the mobility of the sample of outflow and fine.In addition, gas Body can also be flowed directly out and be flowed into around isolation filter bowl, play the role of pressurization and decompression.
Preferably, the sampling channel is provided with plug valve, the plug valve is used to open or closes the sampling channel.
Preferably, the sampler includes sampling needle tubing, the sampling needle tubing is connected to the sampling channel, and passes through institute It states plug valve and opens the sampling channel.
Preferably, the plug valve includes spool and spring, the sampling needle tubing contradicts and pushes the spool, the spring For applying a restoring force to the spool.
Preferably, the sampler is air pump or liquid pump.
On the basis of common knowledge of the art, above-mentioned each optimum condition can be combined arbitrarily to get each preferable reality of the present invention Example.
The positive effect of the present invention is that:It is deflated and is arranged by the suction of sampler, sample can be accurately controlled The amount of outflow.This programme compact overall structure, it is easily stored, it can also accurate convenient automatic sampling in family.

It is further illustrated the present invention below by the mode of embodiment, but does not therefore limit the present invention to the reality It applies among a range.In the following examples, the experimental methods for specific conditions are not specified, according to conventional methods and conditions, or according to quotient Product specification selects.
As shown in Fig. 1-Fig. 7, present embodiment discloses a kind of samplers comprising one for smash the container 1 of sample with An and sampler for absorbing or discharging gas.
As shown in Figure 1, container includes an ontology 1, ontology 1 is provided with a gas passage 11 and one sampling channel 12, wherein The sampler is connected to gas passage 11, and absorbs or discharge the gas in container by gas passage 11.
As shown in Figures 2 and 3, the part-structure for smashing the container of sample can be such as blender, ultrasonic grinder Structure is crushed Deng common, can play the role of smashing sample.A grinder 9, grinder 9 is used to be located at institute in the present embodiment State the center of container.Wherein, grinder 9 is driven by underlying motor 5, to rotary motion.Certainly, grinder 9 It can be common blender, can also be ultrasonic grinder etc..
As shown in Figure 5 and Figure 6, gas passage 11 include interior connector 111 and outer connector 112, outer connector 112 with take Sampling device is connected to.
Interior connector 111 is located at the upper end of ontology 1, and sampling Channel 12-Bit is in the lower end of ontology 1.Interior connector 111 is arranged In the top of ontology 1, sample just may not flow into gas passage 11 and cause to reveal as a result,.In addition, sampling channel 12 is arranged in ontology 1 lower end is conducive to the outflow of sample.
