[0027] ​The exhaust gas inlet assembly 3 comprises an exhaust gas inlet pipe 301 arranged at the side of the air inlet 2, and the end of the exhaust gas inlet pipe 301 is provided with a fixed connection ring 302, which is sleeved on the air inlet 2. The end of the exhaust gas inlet pipe 301 is connected with a side connecting block 303, the middle part of the side connecting block 303 is provided with an air inlet channel 304, the bottom wall of the air inlet channel 304 is provided with an air inlet groove 305, the air inlet groove 305 is communicated with a first air inlet pipe 306, and the bottom end of the first air inlet pipe 306 is communicated with an external air inlet pipe 307.

[0028] The exhaust gas inlet pipe 301 is slidably inserted with a mixed air prevention cylinder 308, the end of the mixed air prevention cylinder 308 is provided with an air inlet hole 309, the side of the mixed air prevention cylinder 308 is provided with a closing plug 310, the side of the closing plug 310 is connected with a fixed connection frame 311, a plurality of mounting insertion holes 312 are arranged on the fixed connection frame 311, a plurality of connecting screws 313 are uniformly arranged at the end of the mixed air prevention cylinder 308, the ends of the connecting screws 313 penetrate the mounting insertion holes 312, and the ends of the connecting screws 313 are sleeved with connecting nuts 314.

[0029] The outer side of the air inlet 2 is provided with external threads, and the inner wall of the fixed connection ring 302 is provided with internal threads matched with the air inlet 2.

[0030] In the second embodiment, the diameter of the fixed connection frame 311 is the same as the opening diameter of the air inlet channel 304.

[0031] The fixed connection frame 311 can be completely inserted into the air inlet channel 304, and the mixed air prevention cylinder 308 is completely inserted into the exhaust gas inlet pipe 301.

[0032] In the third embodiment, the mixed air prevention cylinder 308 is in the form of a cylinder with one end open.

[0033] The gas entering the mixed air prevention cylinder 308 is more convenient to discharge into the air inlet 2.

[0034] In the fourth embodiment, the outer side of the closing plug 310 is provided with external threads, and the inner wall of the air inlet groove 305 is provided with internal threads matched with the closing plug 310.

[0035] The closing plug 310 and the side connecting block 303 are more convenient to disassemble, and the closing of the air inlet groove 305 is more airtight.

[0036] In the embodiment, since the existing organic waste gas detector is used in actual use, the gas inlet pipe arranged thereon will inevitably have more organic particles remaining on the inner wall thereof in the repeated use process. If the remaining organic particles are not cleaned in time, they will be mixed in the subsequent entering waste gas, thereby greatly affecting the detection accuracy of the waste gas detector and the normal use of the user.

[0037] In summary, when the user needs to connect the organic waste gas to be detected to the inside of the organic waste gas detection box main body 1 through the gas inlet 2, and the organic waste gas detection box main body 1 is an existing product on the market, such as model XS-9000L-VOC, the user first needs to insert the fixed connection ring 302 on the gas inlet 2, so that the fixed connection ring 302 is connected with the gas inlet 2 through threads, and the anti-mixing gas inlet cylinder 308 is inserted into the waste gas inlet pipe 301. The end of the waste gas inlet pipe 301 is provided with a side connecting block 303, and the anti-mixing gas inlet cylinder 308 can enter the waste gas inlet pipe 301 through the fixed connecting frame 311 and the closing plug 310 penetrating the gas inlet groove 305 in the middle of the side connecting block 303.

[0038] The fixed connecting frame 311 is inserted into the gas inlet groove 305, and the end of the closing plug 310 is inserted into the side of the gas inlet groove 305 and connected with the threads arranged on the gas inlet groove 305 through the threads arranged on the closing plug 310, thereby facilitating the user to pull out the anti-mixing gas inlet cylinder 308 inserted into the waste gas inlet pipe 301 later. The organic waste gas to be detected enters the first gas inlet pipe 306 through the external gas inlet pipe 307, enters the gas inlet groove 305 through the first gas inlet pipe 306, and then enters the gas inlet 2 through the anti-mixing gas inlet cylinder 308 and the gas inlet opening 309 in sequence, and is detected in the organic waste gas detection box main body 1 through the gas inlet 2.

[0039] Since the anti-mixing gas inlet cylinder 308 is arranged in the waste gas inlet pipe 301, the organic particles contained in the gas passing through the waste gas inlet pipe 301 will only adhere to the inner wall of the anti-mixing gas inlet cylinder 308. When the user needs to detect different organic waste gas, the user only needs to rotate the closing plug 310 to pull out the anti-mixing gas inlet cylinder 308 inserted into the waste gas inlet pipe 301 through the fixed connecting frame 311, and then unscrew the connecting nut 314 sleeved on the connecting screw 313 to detach the anti-mixing gas inlet cylinder 308 from the fixed connecting frame 311. Replace the clean anti-mixing gas inlet cylinder 308, so that the clean anti-mixing gas inlet cylinder 308 is inserted into the waste gas inlet pipe 301 again, thereby effectively ensuring that the organic waste gas passing through the waste gas inlet pipe 301 will not be affected by the previously remaining organic waste gas particles, so that the organic waste gas detection box main body 1 can detect the organic waste gas more accurately each time, and the user can use it more conveniently.
