DETAILED DESCRIPTION

[0026] The present application will be further described in detail below with reference to the drawings.

[0027] Embodiment:

[0028] Referring to Figures 1-3 The present application discloses a multi-channel gas analyzer, which comprises a mounting seat 1, wherein the mounting seat 1 is embedded with a gas analyzer body 2, an annular groove 3 is formed in the top side middle part of the mounting seat 1, an annular support belt 5 is connected with the annular groove 3 through a driving member 4, and a plurality of gas extraction mechanisms 6 are arranged on the top side of the annular support belt 5.

[0029] The air extraction mechanism 6 includes a groove 7, an air chamber tube 8, a piston plate 9, a spring 10, and a slide rod 11. The groove 7 is formed on the top side of the annular support belt 5. The air chamber tube 8 is fixedly connected to the groove 7. The piston plate 9 is slidably connected to the air chamber tube 8 and is dynamically sealed. The slide rod 11 is slidably connected to the top of the air chamber tube 8. The bottom end of the slide rod 11 extends into the air chamber tube 8 and is connected to the piston plate 9. The spring 10 is connected to the top side of the piston plate 9. The top end of the spring 10 is connected to the top side wall inside the air chamber tube 8. A control element 12 is provided at the bottom of the annular groove 3.

[0030] In this embodiment, reference Figure 1 The mounting base 1 is used to mount the air extraction mechanism 6 and the drive component 4. (See reference...) Figure 2 The gas analyzer body 2 is installed inside the mounting base 1. When gas extraction is required for analysis, refer to... Figure 2 The drive mechanism drives the annular support belt 5 to rotate. As the annular support belt 5 rotates, it also moves the air chamber tube 8 located in the groove 7. When it reaches the designated position, the control component 12 pulls the slide rod 11. Figure 4 When the slide bar 11 is pulled, the piston plate 9 inside the air chamber tube 8 will move. At the same time, the movement of the piston plate 9 will compress the spring 10 until the slide bar 11 pulls the piston plate 9 to the appropriate position. At this time, the drive component 4 continues to drive the annular support belt 5 to rotate. Then, the air chamber tube 8, which has been evacuated, is moved to the air inlet point of the gas analyzer body 2. During this period, the air chamber tube 8 is in a closed state. When it reaches the gas analyzer point, the reset of the spring 10 will push the piston plate 9 downward, thereby injecting the air evacuated in the air chamber tube 8 into the gas analyzer body 2, while avoiding the presence of residual air in the air chamber tube 8.

The bottom of the gas delivery head 14 is flush with the bottom side wall of the annular groove 3. When the annular support belt 5 rotates, it will move the gas chamber tube 8. After the gas chamber tube 8 has finished evacuating, it will move the gas delivery head 14 to the position of the ventilation slot 13. (See reference...) Figure 4 In the gas chamber tube 8, the piston plate 9 inside the gas chamber tube 8 will be pushed downward by the spring 10, thereby injecting gas from the gas delivery head 14 into the gas analyzer body 2 for analysis.

[0033] In addition, the bottom end of the gas delivery head 14 is in a dynamic seal state when it is in contact with the inner bottom side wall of the annular groove 3, so as to avoid air leakage and other gas entering the gas chamber tube 8, which would affect the accuracy of gas analysis.

When the hose 16 returns to its cylindrical shape, the solenoid valve 18 is closed. The gas in the hose 16 is then drawn out by the suction device. After the gas in the hose 16 is drawn out, it will be compressed, which will greatly reduce the residual air and reduce the influence of the air in the original air intake pipeline when the gas analyzer detects gas.
