Wherein, the plug end of the signal pin base 103 is exposed outside the opening.

Referring to fig. 2, the upper case has a boss 12 on an inner surface of a top wall thereof, and a bottom surface of the boss 12 abuts against a top surface of the electronic control board 101, so that the electronic control board 101 can be fixed, thereby improving the shock resistance of the main board assembly 10. Wherein the location of the boss 12 corresponds to the location of the recess in the top wall of the upper housing. It can be understood that the boss 12 is provided with an avoidance groove structure for avoiding the electronic components on the electronic control board 101, and meanwhile, the avoidance grooves can also realize the internal communication between the waterproof ventilation valve 5 and the controller.
