[0025] Further as Figure 1As shown, it is worth noting that the air pump 3, automatic sealing valve 5, thermal gas mass flow meter 6, and concentration calibrator 7 are interconnected via connecting pipe 4. Both the input end of the air pump 3 and the output end of the concentration calibrator 7 are equipped with connecting components 9. Through the connection relationship between the connecting components 9 and the hose 11, it is convenient for the connecting components 9 to be connected to each other via the hose 11. The connection relationship is as follows: one end of the hose 11 is fitted onto the cone head 9021 and the second limiting ring 9024 of the connecting component 9. Then, the rubber ring 903 is fitted onto the outside of the hose 11 at the lower end of the cone head 9021 and the second limiting ring 9024. Then, the fixing ring 901 is rotated, and the fixing ring 901 moves forward, thereby causing the first limiting ring 9012, the rubber ring 903, and the second limiting ring 9024 to fit tightly together. The structure is simple and easy to operate, not only fixing one end of the hose 11 but also increasing the airtightness.

[0026] Further as Figure 1 As shown, it is worth noting that the input end of the collection tube 10 and one end of the sampling probe 8 are provided with a connecting component 9, and the output end of the collection tube 10 is provided with an exhaust valve 1001.

Then, the rubber ring 903 is sleeved on the outside of the hose 11 at the lower end of the cone head 9021 and the second limiting ring 9024. Then, the fixing ring 901 is rotated, and the fixing ring 901 moves forward, so that the first limiting ring 9012, the rubber ring 903 and the second limiting ring 9024 fit tightly together. The structure is simple and easy to operate. It can not only fix one end of the hose 11, but also increase the airtightness. The air outlet valve 1001 facilitates the use of the collection tube 10.

The fixing sleeve 801 and the connecting sleeve 802 each have a positioning groove 8011 or a raised guide 8021 in the middle of opposite sides. The positioning groove 8011 has a sealing gasket, and the raised guide 8021 can be slidably connected to the corresponding positioning groove 8011. The fixing sleeve 801 and the connecting sleeve 802 can be fixedly connected by bolts through adjacent fixing holes 8041, which makes it easy to disassemble and assemble the fixing sleeve 801 and the connecting sleeve 802, and facilitates the replacement of the three-stage filter structure. The raised guide 8021 can be slidably connected to the corresponding positioning groove 8011, which facilitates the docking of the fixing sleeve 801 and the connecting sleeve 802 and increases the airtightness of their docking point.

[0033] Further as Figure 3 As shown, it is worth noting that the connector 805 is teardrop-shaped, and several air inlet grooves 806 are provided in the middle of the curved surface at one end of the connector 805.

Simultaneously, the calibration mode is selected via the touch screen 13, and the device can automatically complete flow and concentration calibration. The thermal gas mass flow meter 6 and the concentration calibrator 7 work synchronously. The control center 12 records data and generates a calibration report. The high temperature and pressure resistance of the silicone hose 11 increases the applicability of the device. The connecting component 9 at one end of the sampling probe 8 facilitates disassembly and replacement, and the sampling probe 8 also features a three-stage quick-release mechanism. The filter structure (PTFE filter membrane 807, glass fiber filter membrane 808, or metal filter screen 809) provides staged filtration, extending the filter membrane life and improving sampling accuracy. Adjacent fixing holes 8041 can be bolted together, facilitating the disassembly and assembly of the fixing sleeve 802 and connecting sleeve 801, and enabling replacement of the three-stage filtration structure. The protruding guides 8021 allow for a smooth sliding connection to the corresponding positioning groove 8011, facilitating the docking of the fixing sleeve 802 and connecting sleeve 801 and increasing the sealing at the docking point.
