The driving gear 111 is arranged at one end of the driving shaft 106, and the driven gear 107 is arranged on one side of the transfer tube 103. One end of the driving shaft 106 is connected to the driving motor 101 located in the detector housing 5 through the reducer 102. The transfer tube 103 can be rotated laterally through the transmission of the driving gear 111 and the driven gear 107.

[0025] First, the driving motor 101 drives the driving shaft 106 to rotate, the driving shaft 106 drives the driving gear 111 to rotate, the driving gear 111 drives the driven gear 107 to rotate, the driven gear 107 drives the transfer tube 103 to rotate, the transfer tube 103 rotates on the air intake pipe 7 through the rotating joint 112, the rotation of the transfer tube 103 drives the turntable 108 to rotate, the transfer tube 103 drives the air intake hood 2 to rotate through the pitch adjustment mechanism 3, and adjusts the lateral angle of the air intake hood 2, the air intake hood 2 delivers air to the transfer tube 103, the transfer tube 103 delivers air to the air intake pipe 7, and the air intake pipe 7 delivers air to the detection chamber 6 for detection.

[0026] Specifically, a guide slider 110 is provided on the outer surface of the turntable 108, and one end of the guide slider 110 is slidably provided in an annular guide groove, and the annular guide groove is provided on the inner surface of the opening 109. The rotation of the transfer tube 103 drives the turntable 108 to rotate, and the rotation of the turntable 108 drives the guide slider 110 to rotate in the annular guide groove, thereby ensuring the stability of the rotation of the turntable 108.

[0027] Furthermore, a guide sleeve 105 is disposed on one side of the bearing seat 104 , and the driving shaft 106 is rotatably disposed in the guide sleeve 105 , thereby improving the stability of the driving shaft 106 during rotation.

[0028] In one specific embodiment, see Figure 2 and Figure 5 A pitch adjustment mechanism 3 for adjusting the pitch angle of the air intake hood 2 is arranged on one side of the outer surface of the transfer tube 103.
