[0039] In this embodiment, the cleaning liquid delivery pump 18 fixedly connected to the side of the sampling box 8 can deliver the cleaning liquid to each key part inside the sampling box 8, including the solid collection cavity 22, the liquid collection cavity 23, the first gear cylinder 20, the second gear cylinder 24, etc. The cleaning liquid can effectively dissolve and remove the residual samples and impurities in these parts, preventing cross-contamination between different samples. This is particularly important for chemical samples that require high-precision detection, which can ensure the independence and accuracy of each sampling and improve the reliability of the detection results.

[0040] In one embodiment, for the above-mentioned connecting rod 16, a zigzag soft pad is provided on the surface of the handle 1.

[0041] In this embodiment, by providing a zigzag soft pad on the surface of the handle 1, the stable holding of the user is ensured.

[0042] In one embodiment, for the above-mentioned cavity gear 27, a circular cavity 26 is rotatably connected to the side of the cavity gear 27 close to the second belt 20.

[0043] In one embodiment, a pump for sucking the residual slag on the inner wall of the first gear cylinder 20 is provided on the side of the sampling box 8, and a pump for sucking the residual liquid on the inner wall of the second gear cylinder 24 is provided on the side of the sampling box 8.

[0044] The working principle of a combined sampler for chemical detection in the present invention is that first, the user takes samples according to chemical detection. First, there is a sampling box in three states inside the sampler housing 2. Taking Figure 6 as an example, the leftmost one is the solid collection cavity 22 for solid sampling, then the middle part is the liquid collection cavity 23 for liquid sampling, and the rightmost one is the gas collection cylinder 25 for gas sampling. The initial position is that the gas collection cylinder 25 is at the sampling port 4. If gas sampling is required, first press down the pressing lever 34, then control the button on the surface of the control panel 6, select one of the three state buttons, and then the sampling mode can be adjusted. First, connect a disposable suction pipe to the surface of the gas extraction pump port 16, then the gas enters into the gas collection cylinder 25. Then place a collection bag on the back interface at the back of the storage box 7, and then start the gas delivery block on the side to deliver the non-reactive gas into the cylinder inside the gas collection cylinder 25. As the non-reactive gas enters, the collected gas will be compressed into the bag. Take a small part, and the remaining part has a lower purity and should be properly processed after collection.

[0045] Then, if liquid sampling for chemical testing is required, press down the lever 34, and then control the buttons on the surface of the control panel 6 to adjust the suction pump port 15 for liquid sampling to align with the sampling port 4. Then, insert a disposable liquid suction pipe into the interface on the surface of the suction pump port 15. Then, the liquid is sucked into the liquid collection chamber 24. Then, use a collection bag to connect to the outlet on the back of the storage box 7. Since the side of the liquid collection chamber 24 close to the suction pump port 15 is at a higher position, as the liquid enters the liquid collection chamber 24, the liquid collection chamber 24 will tend to move away from the suction pump port 15, thus realizing the flow of the liquid, and then collecting it into the collection bag. As the liquid continuously enters the collection bag, finally, the pipeline inside the liquid collection chamber 24 stops flowing, and the liquid collection is completed.

[0046] Then, press down the lever 34 by oneself at this time, and then control the buttons on the surface of the control panel 6 to collect other chemical materials. At this time, the cleaning liquid in the cleaning liquid placement box 13 will be brought into the liquid collection chamber 24 by the cleaning liquid delivery pump 18. Then, when switching to the mode of collecting other chemical materials, the movement of the sampling box 8 will use the second rotating gear 11 at its bottom to engage with the fixed block 35. Then, the second rotating gear 11 drives the fourth gear 26 to rotate by using the second belt 12. The rotation of the fourth gear 26 will engage with the second gear cylinder 24. At the same time, the rotation of the fourth gear 26 will drive the half gear block 33 to rotate by using the transmission belt on the side of the sampling box 8. The rotation of the half gear block 33 will first engage with the first inner ring rack 31, and then the elliptical ring 30 will move upward. As the engagement of the half gear block 33 with the first inner ring rack 31 is completed, it will continue to engage with the second inner ring rack 32, and the elliptical ring 30 will descend, thus realizing the intermittent up and down movement of the first cleaning brush 27 and the second cleaning brush 28. And as the second gear cylinder 24 continuously rotates, the inner wall of the second gear cylinder 24 will be cleaned. Finally, the electric pump block on its back will use the pipeline in the sandwich layer of the sampling box 8 to transport the sewage to the cleaning liquid placement box 13 to clean the sewage.

[0047] Continue to press the downward pressing lever 34. At this time, switch to the solid collection mode. Then insert the primary liquid collection tube on the surface of the dust suction pump port 14. The dust suction pump port 14 will suck the solid into the inside of the first gear cylinder 20 by the dust suction principle. Then, after the solid enters the inside of the first gear cylinder 20, it will be secondarily sucked by the dust suction pump on the side of the sampling box 8 and thus enter the collection bag. At this time, when switching to other modes, the first rotating gear 9 will engage with the fixed block 35. Thus, the fixed block 35 drives the third gear 19 to rotate by means of the first belt 10. The third gear 19 will engage with the fixed scraping plate 21. The fixed scraping plate 21 fixed inside the solid collection chamber 22 will scrape the inner wall of the first gear cylinder 20, thereby cleaning it. As the switching is completed to the next mode, at this time, the scraping inside the solid collection chamber 22 is completed. The solid pump on the side of the sampling box 8 sucks and stores it in the collection box on one side, thus completing the cleaning. Then clean it up later.

[0048] The above-mentioned sliding during the detection of other chemical materials is realized by the engagement of the fixed rack 37 inside the sampler housing 2, the second rotating gear 11 at the bottom of the sampling box 8, the first rotating gear 9 and other gears.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
