[0012] like Figures 1-3 As shown: A sampling device for detecting soapberry stock solution includes a sampling bottle 1. A piston-type sampler is located on the right side of the sampling bottle 1. The piston-type sampler includes a circular tube 5 and a piston 11. A connecting tube 6 is fixedly connected to the top of the left end of the circular tube 5. A bottle cap 2 is threadedly connected to the top of the sampling bottle 1. The top of the bottle cap 2 is fixedly connected to one end of a sampling tube 3 and one end of a suction tube 4. Both ends of the sampling tube 3 and the suction tube 4 penetrate the bottle cap 2. The sampling tube 3 and the suction tube 4 are respectively connected to the interior of the sampling bottle 1. The other end of the sampling tube 3 extends downwards to the left, and the other end of the suction tube 4 extends to the right and connects to the connecting tube. 6. Threaded connection. A one-way valve 7 is installed inside the connecting pipe 6. The one-way valve 7 leads to the inside of the round pipe 5. The bottom left end of the round pipe 5 is fixedly connected to an exhaust pipe 8. A one-way valve 9 is installed inside the exhaust pipe 8. The one-way valve 9 leads to the outside. The top right end of the round pipe 5 is fixedly connected to a vent pipe 10. The round pipe 5 has a piston 11. The piston 11 is slidably connected to the inner wall of the round pipe 5. A pull rod 12 is fixedly connected to the middle of the right side wall of the piston 11. The right end of the pull rod 12 passes through the right side wall of the round pipe 5. The pull rod 12 is slidably connected to the right side wall of the round pipe 5. A handle 13 is fixedly connected to the right end of the pull rod 12.

[0013] Initially, the sampling bottle 1 is empty, the piston 11 inside the round tube 5 is at the leftmost position, and the lever 12 and handle 13 extend to the right.

[0014] During sampling, the sampling tube 3 is inserted into the sample container 14, which contains saponin concentrate. By pulling the lever 12 to the right using the handle 13, the piston 11 moves to the right within the circular tube 5, creating a negative pressure within the tube. Under this negative pressure, the saponin concentrate in the sample container 14 enters the sampling bottle 1. When the piston 11 reaches its rightmost position, one extraction operation is completed.

[0015] Pushing lever 12 to the right by grip 13 opens one-way valve 7 and closes one-way valve 9, creating negative pressure in circular tube 5, allowing the soapberry stock solution in sample container 14 to enter sampling bottle 1. When piston 11 is moved to the left, one-way valve 7 closes and one-way valve 9 opens, allowing gas to be discharged to the outside through exhaust pipe 8, thereby reducing the pressure inside circular tube 5.

[0016] By repeating the above steps of extracting and venting gas, sample liquid can be continuously extracted from sampling bottle 1 into round tube 5.

[0017] When the sample bottle 1 reaches the required sampling amount, stop pulling and pushing the pull rod 12, because the bottle cap 2 is threadedly connected to the top of the sample bottle 1, the sample bottle 1 can be separated from the bottle cap 2, and the saponin stock solution in the sample bottle 1 can be taken away.
