Further, to make the end of the inner fill tube 223 that defines the fill port 221 easier for the user to hold, in some embodiments, the end of the inner fill tube 223 distal from the fill port is provided as a collapsible structure 2231 and the end proximal to the fill port is provided as a rigid structure 2232, with the collapsible structure 2231 having a length of at least one-half the length of the inner fill tube 223. The collapsible structure 2231 is provided with sufficient length to allow the inner fill tube 223 to extend a distance after it has been pulled out of the outer fill tube 224 by a maximum predetermined length value, increasing the applicability.

In some embodiments, the tubular section diameter of the collapsible structure 2231 is smaller than the tubular section diameter of the rigid structure 2232. In this manner, collision friction between telescoping structure 2231 and the inner wall of outer syringe 224 during movement is avoided.

In other embodiments, the inner fill pipe 223 may be a segmented telescopic structure, which is made of hard material, and the inner fill pipe 223 has at least two segments. When the inner filling pipe 223 is in a shortened state, one section of two adjacent sections of the inner filling pipe 223 is sleeved outside the other section of the inner filling pipe 223, and when the inner filling pipe 223 is in an extended state, one section of two adjacent sections of the inner filling pipe 223 extends out of the other section of the inner filling pipe 223 by a certain length.

In some embodiments, referring to fig. 9, at least a portion of outer nozzle 224 is provided with a resilient damping structure 2241, and resilient damping structure 2241 is resiliently compressible and repositionable along an axial direction of outer nozzle 224. So, at vehicle 1's the in-process of traveling, when meetting the heavy object and striking preceding cabin, can provide certain buffer capacity, reduce the injury to the heavy object, accord with the security performance requirement.

In some embodiments, the fill port 221 is a flat port or a beveled port. In the embodiment shown in fig. 9, the filler port 221 is provided as a slant port because the vent cover 14 is inclined at a certain angle with respect to the gutter channel 40.
