according to the invention, the intercepting pipe 17 is arranged below the mounting plate 2, the intercepting pipe 17 rotates one end of the mounting frame bracket 16, then the intercepting pipe 17 is locked through the locking assembly, the collecting box 5 needs to align the collecting port 8 above the collecting box with the exhaust pipe 15 of the air pump 6 when an air sample is collected, but the intercepting pipe 17 can block the collecting box 5 in the rotating alignment process of the collecting box 5, if the locking assembly needs to be unlocked, air needs to be supplied into the intercepting pipe 17 through the air pump 6, the air pump 6 can supply air into the intercepting pipe 17 through the exhaust pipe 15 to discharge the original air in the air pump 6, the collecting box 5 can push the intercepting pipe 17 to rotate after the locking assembly is unlocked through the air pump 6, then the air pump 6 can convey the air sample into the collecting box 5 after the collecting port 8 on the collecting box 5 is aligned with the exhaust pipe 15 of the air pump 6, and the air sample conveyed by the air pump 6 is sucked from the air in the current position, so that the accuracy of the sample is ensured, and the problem that the detection accuracy is influenced because the original air in the air pump 6 enters the collecting container when the traditional sample is collected is solved.
As a further scheme of the invention, one end of the bracket 16 close to the collecting box 5 is fixedly provided with a mounting rod 18, the upper end of the mounting rod 18 is fixedly provided with a lug 19, the lower end of the intercepting tube 17 is rotatably connected with the lug 19, the locking assembly comprises a slider 20, a return spring 21, a first fitting surface 22 for locking and returning the intercepting tube 17 and a second fitting surface 23 matched with the first fitting surface 22, the slider 20 is slidably connected with the mounting rod 18, the return spring 21 is arranged between the lower end surface of the slider 20 and the upper end surface of the bracket 16, the upper end surface of the slider 20 is provided with the first fitting surface 22, and the lower end of the intercepting tube 17 is provided with the second fitting surface 23;
in operation, as shown in fig. 6-8, when the first fitting surface 22 and the second fitting surface 23 are completely fitted, the sliding block 20 locks the intercepting tube 17, and the upper end of the intercepting tube 17 is aligned with the outlet of the exhaust pipe 15, at this time, the collecting box 5 cannot push the intercepting tube 17, if the sliding block 20 is required to unlock the intercepting tube 17, the first fitting surface 22 and the second fitting surface 23 are required to be separated from contact, at this time, the air pump 6 can be started, the air pump 6 supplies air into the intercepting tube 17 through the exhaust pipe 15, because the intercepting tube 17 is rotatably connected with the protruding block 19 and the sliding block 20 is slidably connected with the mounting rod 18, the sliding block 20 is pushed downwards when the air pump 6 inflates the intercepting tube 17 through the exhaust pipe 15, at this time, the first fitting surface 22 and the second fitting surface 23 start to separate, and after the first fitting surface 22 and the second fitting surface 23 separate, air begins to leak from a gap between the lower surface of the intercepting tube 17 and the upper surface of the sliding block 20, but the air sent into the intercepting tube 17 by the air pump 6 directly impacts the sliding block 20 from top to bottom after leaving from the lower part of the intercepting tube 17, the sliding block 20 can continue to descend through the impact of high-speed air, the return spring 21 below the sliding block 20 is compressed, the first fit surface 22 and the second fit surface 23 are completely separated after the sliding block 20 descends to a certain height, at the moment, the limit of the intercepting tube 17 by the sliding block 20 disappears, the collecting box 5 can smoothly push the intercepting tube 17 to rotate around the lug 19, then the collecting port 8 at the upper end of the collecting box 5 can be aligned with the exhaust pipe 15 of the air pump 6, the compressed return spring 21 can push the sliding block 20 to ascend in the process of feeding air into the collecting box 5, due to the special shape design of the first fit surface 22 and the second fit surface 23, the return spring 21 is enabled to rotate when the slide block 20 is pushed to ascend so that the interception pipe 17 can continue to rotate until the upper end of the interception pipe 17 rotates to be aligned with the exhaust pipe 15, the first fit surface 22 and the second fit surface 23 are completely fit, the return spring stops, but at the moment, the collection box 5 is located below the exhaust pipe 15, so that the interception pipe 17 cannot be reset smoothly, when the collection box 5 continues to rotate after collection is completed, the interception pipe 17 is attached to the right end of the collection box 5 and rotates along with the collection box 5 until the opening at the upper end of the interception pipe 17 is aligned with the opening of the exhaust pipe 15 again, so that the interception pipe 17 can intercept the next collection box 5, automatic reset of the interception pipe 17 is realized, all the collection boxes 5 need to send air into the interception pipe 17 by the air pump 6 before being aligned with the exhaust pipe 15 to unlock the interception pipe 17, the fact that the original air in the air pump 6 must be exhausted before collection every time is ensured, and collection accuracy is ensured;
according to the invention, the first fit surface 22 is arranged on the upper end surface of the sliding block 20, the second fit surface 23 is arranged at the lower end of the intercepting pipe 17, the intercepting pipe 17 can be locked in a single direction through the fit of the first fit surface 22 and the second fit surface 23, meanwhile, due to the special shapes of the first fit surface 22 and the second fit surface 23, the intercepting pipe 17 can be reset when the reset spring 21 pushes the sliding block 20 to ascend, and before the acquisition opening 8 above each acquisition box 5 and the exhaust pipe 15 acquire samples in a mouth-to-mouth mode, the air pump 6 is required to supply air to unlock the intercepting pipe 17, so that the acquired samples are air in the current area, and the situation that the original air in the air pump 6 enters the acquisition box 5 to influence the final detection result is ensured.
As a further scheme of the invention, the horizontal height of the upper end surface of the interception pipe 17 is the same as the horizontal height of the acquisition opening 8 of the acquisition box 5;
during operation, the air supply effect of the exhaust pipe 15 into the intercepting pipe 17 is ensured to be the same as the air supply effect of the exhaust pipe 15 into the collecting box 5.
