Meanwhile, the ejector 300 can be directly pulled out when the first filter 350 needs to be cleaned, which is convenient.
A second support ring 202 is disposed in the second tank 200, and a second filter 203 is disposed on the second support ring 202. The water flowing into the second tank 200 can be further filtered through the second filter screen 203, so that impurities in the water can be further removed, and the influence of the impurities on water quality detection can be prevented.
The bottom of the second tank 200 is provided with a boss 204, a third opening 206 is arranged on the boss 204, the third opening 206 is a water outlet, and the third opening 206 is plugged by a plug 400. The plug 400 is pulled out when the second tank 200 needs to be discharged. Meanwhile, the position of the water outlet can be higher than the bottom surface of the second tank body 200 through the boss 204, so that impurities settled on the bottom surface of the second tank body 200 cannot flow out along with the water outlet, and the purity of the water outlet is ensured.
The third opening 206 is provided with a third plug interface 207, the plug 400 is provided with a fourth plug interface 410, and the plug 400 is embedded into the third opening 206 by plug-in fit of the third plug interface 207 and the fourth plug interface 410.
During sampling, the first tank 100 and the second tank 200 are separated, the bottom of the first tank 100 is slowly immersed into the water to be measured downwards, the floating plug 112 is opened by water under the action of water pressure to enable the floating plug 112 to move upwards, water enters the first tank 100 through the water inlet gap between the floating plug 112 and the side wall of the collecting tank 110 and the water inlet 111, and meanwhile, the water inlet 111 also filters impurities with partial volume being larger. When the water pressure inside the first tank 100 is balanced with the water pressure outside the first tank 100, the first tank 100 is quickly lifted, and the floating plug 112 moves downward in the collection tank 110 due to inertia and closes the first opening 102. When the first tank 100 is discharged, the floating plug 112 is pressed under the action of the water pressure in the first tank 100, so that the floating plug 112 further seals the first opening 102 to prevent the water in the first tank 100 from flowing out. Then, the first plug connector 120 on the first can 100 is inserted into the second plug connector 210, so that the ejector rod 310 in the second can 200 pushes the floating plug 112 open, the water in the first can 100 flows into the second can 200 and is filtered by the first filter screen 350 and the second filter screen 203, and finally the water discharged from the third opening 206 is detected.
When cleaning is needed, the first top cover 101 is opened to clean the interior of the first can 100. The second top cover 201 is opened to clean the inside of the second can 200, and the second filter 203 can be cleaned and replaced.
