[0033] Specifically, the wall 9 of the fuel delivery channel 21 has an outer wall 91 and a through hole 213. The sensing part of the humidity sensor 6 is located on the outer wall 91. The sensing part of the humidity sensor 6 is arranged corresponding to the position of the through hole 213. A water-absorbing and quick-drying material 7 is arranged between the outer wall 91 and the sensing part of the humidity sensor 6. The water-absorbing and quick-drying material generally adopts polyamide fiber. The upper and lower sides of the water-absorbing and quick-drying material 7 are respectively attached to the outer wall 91 and the sensing part of the humidity sensor 6, and the water-absorbing and quick-drying material 7 covers the through hole 213. The humidity sensor 6 is fixed to the outer wall 91 through the shell 8.
