It can be inserted into the exhaust gas outlet to absorb and detect the exhaust gas. When moving for detection, the connecting pipe 4 can be extended and retracted to facilitate detection at different positions of the exhaust gas outlet, thereby improving the accuracy and convenience of exhaust gas detection. A connecting block 5 is provided on the outside of the connecting tube 3 at the bottom of the probe 7, and a protective cover 6 is provided on the top of the connecting block 5. The top of the protective cover 6 has an opening, and a sealing plate 15 is hinged to one side of the opening at the top of the protective cover 6. Threaded rods 11 are provided in the middle of both sides inside the protective cover 6. Threaded blocks 10 are threadedly connected above the threaded rods 11. Connecting rods 17 are provided in the middle of both sides of the threaded blocks 10. A filter frame 9 is provided between the tops of the connecting rods 17. A filter membrane 8 is provided inside the filter frame 9. A slot is provided in the middle of one side of the filter frame 9. Moving slots 16 are provided on both sides of the filter frame 9 corresponding to the positions of the threaded rods 11. Turntables 12 are provided on both sides of the bottom of the protective cover 6 corresponding to the positions of the threaded rods 11. Rotating rods inside the turntables 12 extend into the protective cover 6 and are connected to the corresponding threaded rods 11 through bearings and couplings. In use, the sealing plate 15 can be opened, and then the turntable 12 can be rotated to drive the threaded rod 11 connected to the rotating rod to rotate, so that the threaded rod 11 drives the threaded block 10 to move upward, so that the threaded block 10 drives the filter frame 9 to move upward through the connecting rods 17 on both sides, so that when the filter frame 9 moves upward, the threaded rod 11 passes through the corresponding moving groove 16, and the connecting rod 17 drives the filter frame 9 to move upward and pass through the opening. The Pall 7221 model filter membrane 8 can be taken out through the slot on one side of the filter frame 9, which is convenient for replacing the filter membrane 8. The bottom protective cover 6 of the threaded rod 11 has a through groove corresponding to the position of the probe 7, and the top of the connecting block 5 outside the probe 7 has a rotating groove 20. The middle position of the top of the connecting block 5 on both sides of the rotating groove 20 has a slot 18. The bottom of the protective cover 6 corresponding to the slot 18 has an L-shaped block 21, and the L-shaped block 21 is engaged with the corresponding slot 18 and rotating groove 20. The inner sides of the connecting block 5 have a fan-shaped groove 22 in the clockwise direction corresponding to the L-shaped block 21, and the fan-shaped groove 22 is engaged with the corresponding L-shaped block 21. When in use, the L-shaped locking block 21 at the bottom of the protective cover 6 can be inserted into the corresponding slot 18 on the connecting block 5 to initially engage the protective cover 6. Then, the protective cover 6 can be rotated clockwise to make the L-shaped locking block 21 at the bottom of the protective cover 6 rotate in the fan-shaped groove 22, so that the L-shaped locking block 21 is engaged clockwise on the other side of the fan-shaped groove 22, which facilitates its assembly and disassembly and makes it easier to clean it later. The bottom end of each threaded rod 11 is connected to a threaded block 2 14 by a thread, and each threaded block 2 14 is provided with an L-shaped rod 13 at the middle position on the side near the L-shaped block 21. The bottom of the L-shaped rod 13 is provided with a slot 19 in the protective cover 6, the connecting block 5 and the L-shaped block 21, and the L-shaped rod 13 is inserted into the slot 19 corresponding to the protective cover 6, the connecting block 5 and the L-shaped block 21. In use, the threaded rod 11 drives the threaded block 10 to move down, and at the same time, it drives the threaded block 2 14 to move down. The threaded block 2 14 drives the L-shaped rod 13 on one side to move down together, and the L-shaped rod 13 can be moved and inserted into the corresponding slots 19 of the protective cover 6, the connecting block 5 and the L-shaped locking block 21, so as to fix the protective cover 6 and the connecting block 5.
[0017] In this embodiment of the application, by inserting the L-shaped locking block 21 at the bottom of the protective cover 6 into the corresponding slot 18 on the connecting block 5, the protective cover 6 can be initially engaged. Then, the protective cover 6 can be rotated clockwise, causing the L-shaped locking block 21 at the bottom of the protective cover 6 to rotate within the sector groove 22, so that the L-shaped locking block 21 is engaged clockwise on the other side of the sector groove 22. Then, the turntable 12 is rotated to drive the threaded rod 11 connected to the rotating rod to rotate, so that the threaded rod 11 drives the threaded block one 10 and the threaded block two 14 to move down together. The threaded block one 10 drives the filter frame 9 to move down into the protective cover 6 through the connecting rod, and the threaded block two 14 drives the L-shaped rod 13 on one side to move down into the protective cover 6. The L-shaped rod 13 can be moved downwards to insert into the corresponding slots 19 of the protective cover 6, connecting block 5, and L-shaped locking block 21, thus fixing the protective cover 6 and connecting block 5, facilitating assembly and disassembly, and making subsequent cleaning easier. When analysis and testing are required, the connecting pipe 3, which is locked to the pipe locking block 2 on one side of the analyzer body 1, can be removed, and then the sealing plate 15 of the protective cover 6 can be opened to extend it into the exhaust gas outlet for absorption and testing of the exhaust gas. During mobile testing, the connecting pipe 4 can be extended or retracted to facilitate testing at different positions of the exhaust gas outlet, improving the accuracy and convenience of exhaust gas testing. During testing, the exhaust gas can pass through the Pall... The 7221 model filter membrane 8 is used for filtration to prevent large particulate impurities in the exhaust gas from entering the analyzer body 1 and affecting the analysis and detection results of the analyzer body 1. Then, the sealing plate 15 can be opened periodically, and the turntable 12 can be rotated to drive the threaded rod 11 to rotate, so that the threaded rod 11 drives the threaded block 10 to move upward, so that the threaded block 10 drives the filter frame 9 to move upward through the opening via the connecting rod 17. The Pall 7221 model filter membrane 8 can be taken out through the slot on one side of the filter frame 9, which is convenient for replacing the filter membrane 8.
