A support leg 5 is fixedly connected to the bottom of the tank body 1, a top cover 4 is fixedly connected to the top of the tank body 1, and a sampling mechanism 2 is arranged inside the tank body 1;

[0025] The sampling mechanism 2 includes an outer cylinder 201. The number of the outer cylinders 201 is three. The outer cylinders 201 are movably connected to the inside of the top cover 4 and penetrate into the inside of the tank body 1. An inner rod 202 is slidably connected to the inside of the outer cylinder 201. A piston 203 is slidably connected to the inside of the outer cylinder 201. The bottom of the inner rod 202 is fixedly connected to the top of the piston 203. A circular tube 204 is fixedly connected to the bottom of the outer cylinder 201. The circular tube 204 penetrates to the bottom of the outer cylinder 201. A reaction tank 205 is fixedly connected to the bottom of the inner cavity of the tank body 1. A fixing column 206 is fixedly connected to the inner wall of the reaction tank 205. Limiting grooves 208 are provided on the surface of the fixing column 206 and the surface of the inner cavity of the reaction tank 205. The number of the limiting grooves 208 is three. A limiting plate 207 is clamped in the limiting groove 208.

[0026] Referring to Figure 5 , a shielding mechanism 3 is provided on the top of the top cover 4. The shielding mechanism 3 includes a stopper 301. The stopper 301 is slidably connected to the inside of the top cover 4. Fixing grooves 303 are provided in the inside of the stopper 301 and the inside of the top cover 4. The outer cylinder 201 is movably connected to the inside of the fixing groove 303. By providing the stopper 301, rotating the stopper 301 can block the fixing groove 303, preventing the odor inside the tank body 1 from emitting, and at the same time can support the outer cylinder 201, ensuring the stability of the outer cylinder 201. By providing the fixing groove 303, the outer cylinder 201 can enter the inside of the tank body 1 through the fixing groove 303, providing a passage for the outer cylinder 201 to enter the inside of the tank body 1;

[0027] Referring to Figure 5 , a rotating block 304 is fixedly connected to the bottom of the stopper 301. A rotating groove 305 is provided in the inside of the top cover 4. The surface of the rotating block 304 is slidably connected to the inside of the rotating groove 305. A handle 302 is fixedly connected to the top of the stopper 301. By providing the rotating block 304 and the rotating groove 305, the stopper 301 can rotate inside the top cover 4, and then the fixing groove 303 inside the top cover 4 can be closed;

[0028] Referring to Figure 1 and Figure 5 , threaded holes 13 are provided on both sides of the inner wall of the top cover 4 and both sides of the top of the tank body 1. Threaded rods 8 are threadedly connected to the inside of the threaded holes 13. The tank body 1 and the top cover 4 are fixedly connected through the threaded rods 8. By providing the threaded rods 8 and the threaded holes 13, the tank body 1 and the top cover 4 can be fixedly connected, ensuring the stability of the top cover 4;

[0029] Referring to Figure 1The bottom of the inner cavity of the reaction tank 205 is fixedly connected with a water outlet pipe 6, and the number of the water outlet pipes 6 is three. The water outlet pipes 6 penetrate the bottom of the tank body 1, and one side of the water outlet pipe 6 is fixedly connected with a water control valve 7. By setting the water outlet pipe 6 and the water control valve 7, the unnecessary reaction liquid in the reaction tank 205 can be discharged, which avoids the reaction liquid staying in the reaction tank 205 for a long time and causing pathogenic bacteria contamination;

[0030] Reference Figure 2 The top cover 4 is fixedly connected to a water inlet pipe 12, and there are three water inlet pipes 12. The bottom end of the water inlet pipe 12 is located inside the reaction tank 205. The top of the water inlet pipe 12 is fixedly connected to a funnel 10. The top of the funnel 10 is clamped with a funnel cover 11. By setting the funnel 10 and the water inlet pipe 12, the diluent can flow into the inside of the water inlet pipe 12 through the funnel 10, increasing the inlet area of ​​the diluent entering the water inlet pipe 12 and preventing the diluent from spilling. By setting the funnel cover 11, the top of the funnel 10 can be shielded to prevent the odor inside the tank body 1 from being emitted into the air.

[0031] Reference Figure 1 and Figure 2 The top of the threaded rod 8 is fixedly connected with a protrusion 9, and the bottom of the top cover 4 is fixedly connected with a sealing ring 14. The surface of the sealing ring 14 is tightly fitted to the top of the inner cavity of the tank body 1. By providing the protrusion 9, the contact area between the user's hand and the threaded rod 8 is increased, which makes it convenient for the user to rotate the threaded rod 8. By providing the sealing ring 14, the interior of the tank body 1 can be sealed to prevent the odor from being emitted from the tank body 1.

[0032] Working principle: During use, the experimenter drives the stopper 301 to rotate by turning the handle 302. The rotation of the stopper 301 drives the rotating block 304 to rotate in the rotating groove 305. When the stopper 301 rotates until the two fixing grooves 303 coincide, the outer cylinder 201 is placed inside the tank body 1 through the fixing grooves 303. The top of the outer cylinder 201 is limited inside the stopper 301. Push the inner rod 202, and the movement of the inner rod 202 drives the piston 203 to push downward. The push of the piston 203 squeezes the sample inside the outer cylinder 201 and discharges it into the reaction tank 205 through the round tube 204. There are three limiting plates 207 inside the reaction tank 205, which divide the reaction tank 205 into three spaces. Thus, three samples can be taken from three outer cylinders 201 and reacted simultaneously. Open the funnel cover 11, pour the diluent from the funnel 10 into the inside of the water inlet pipe 12 and transport it to the inside of the reaction tank 205. At this time, the diluent reacts with the sample. After the reaction is completed, pull the inner rod 202. The movement of the inner rod 202 drives the piston 203 to move. The movement of the piston 203 reduces the air pressure inside the outer cylinder 201. The reaction liquid inside the reaction tank 205 is pressed into the inside of the inner rod 202 through the round tube 204 under the action of the external atmospheric pressure. After sampling, the outer cylinder 201 is removed from inside the stopper 301, and then the reaction liquid can be detected.

[0033] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
