The mounting portion 122 is provided with a slope on the mounting outer side (the side away from the housing) of the air filter cover 120, and the base portion 121 gradually protrudes out of the housing when the mounting of the air filter cover 120 is completed.
Alternatively, referring to fig. 5-8, when the functional module is an airtight charging nozzle 130, the airtightness of the casing may be detected by a pressure gauge. The airtight nozzle 130 includes a body portion 131 installed at the functional hole and an assembling portion 132 extending outward from the body portion 131. The two assembling portions 132 are provided, and the two assembling portions 132 extend from the main body 131 to two opposite directions to be symmetrically provided at both sides of the main body.
