In other embodiments, the shielding portion 40 is a sealing cap or plug. The shielding part 40 and the port of the third through hole 341 far from the bottom wall of the groove 31 are arranged in a close fit manner, the port of the third through hole 341 far from the bottom wall of the groove 31 is sealed by the shielding part 40, and an opening 342 is arranged on the side wall of the third through hole 341 of the bulge part 34 to communicate with the third through hole 341 to form a port of the starting air passage 26 far from the airflow sensor 23. The direction of the port of the starting air channel 26 far away from the airflow sensor 23 is perpendicular to the length direction of the shell 21, so that liquid leakage can be prevented from perpendicularly entering the port of the starting air channel 26 far away from the airflow sensor 23, and the air flow sensor 23 is prevented from being damaged by the liquid leakage.

Please refer to fig. 9, which is a schematic structural diagram of another embodiment of the groove of the connecting portion provided in fig. 7.

In another embodiment, the bottom wall of the groove 31 is formed by two inclined planes, and the angle formed by the inclined planes and the length direction of the shell 21 is more than 30 degrees. The projection of the port of the starting air channel 26 far away from the airflow sensor 23 on the bottom wall of the groove 31 is at the highest point of the bottom wall of the groove 31, so that liquid leakage is prevented from contacting the port of the starting air channel 26 far away from the airflow sensor 23 to the maximum extent, and the airflow sensor 23 is protected to the maximum extent.
