[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention discloses an integrated liquid-sealed fuel filling pipe fuel tank assembly, including a fuel tank body 1, a fuel filling pipe 2 and a connecting pipe 6. The connecting pipe 6 is arranged inside the fuel tank body 1. One end of the connecting pipe 6 is fixedly connected to the fuel filling pipe 2, and the fuel filling pipe 2 is fixedly connected to the outside of the fuel tank body 1. The other end of the connecting pipe 6 is fixedly connected to a one-way valve 7.

[0020] Specifically, the connecting pipe 6 is arranged in an inclined shape.

[0021] In this embodiment, by setting the inclined connecting pipe 6, the inclined connecting pipe 6 enables fuel to more easily enter the fuel tank body 1 through the one-way valve 7.

[0022] Specifically, a carbon canister bracket 3 is arranged on the top of the fuel tank body 1.

[0023] In this embodiment, by setting the carbon canister bracket 3, its main purpose is to support and fix the carbon canister. The carbon canister is usually used to store and filter fuel vapor to reduce the emission of fuel vapor into the atmosphere and play a role in protecting the environment.
