[0029] Example 1

[0030] To effectively utilize the space of gasoline-powered vehicles and facilitate efficient space application in small and compact models, this embodiment provides a fuel tank assembly with a dual-chamber integrated water sprayer. (See attached image.) Figures 1-3 It includes a fuel tank assembly 1, a water sprayer assembly 2, a partition 3, and a barrier layer 4; the fuel tank assembly 1 and the water sprayer assembly 2 are separated by the partition 3 to form two independent sealing structures to prevent liquid leakage; the barrier layer 4 is provided between the partition 3 and the fuel tank assembly 1.

[0031] It should be noted that the fuel tank assembly 1 and the water sprayer assembly 2 respectively contain fuel and spray water, and the chambers containing the fuel and spray water are both constructed of welded aluminum alloy, with anti-corrosion treatment applied to the inner cavity and filling port. The barrier layer 4 can be a sheet structure made of EVOH material.

[0032] To improve sealing, see Figure 1 A first sealing layer 5 is provided between the partition 3 and the barrier layer 4; a second sealing layer 6 is provided between the water sprayer assembly 2 and the partition 3 to prevent liquid from flowing between the fuel tank assembly 1 and the water sprayer assembly 2.

[0033] It should be noted that, see Figures 1-3 The water sprayer assembly 2 has a water outlet 7 at its lower part on the side away from the fuel tank assembly 1, and a water inlet 8 at its upper part for adding cooling water. The fuel tank assembly 1 has an oil inlet 9 at its upper part and an oil outlet at its lower part, which is sealed by a drain plug 10. The structural design of the water sprayer assembly 2 and the fuel tank assembly 1 ensures that their liquid inlet and outlet functions do not interfere with each other when installed in the vehicle. This means it has no adverse effects on components installed inside the vehicle, and there is no interference during liquid filling. It is safe, stable, and easy to manufacture, effectively integrating the functions of the fuel tank and the water sprayer. This facilitates the placement of this utility model structure within the vehicle, resulting in a more aesthetically pleasing layout and significantly increasing vehicle space utilization. It is suitable for various commercial vehicles and can be widely adopted.

[0034] A control switch (not labeled in the figure) is provided at the water outlet 7 to control the water flow from the water sprayer assembly 2. The water at the water outlet 7 can be used to cool tires, etc. A fuel level sensor (not labeled in the figure) is provided above the fuel tank assembly 1.

[0035] Example 2

[0036] For ease of installation, please refer to Figure 2 , Figure 3 The fuel assembly device of this utility model also includes a band 11 and a blocking member 12; the band 11 is provided on the outer surface of the fuel tank assembly 1 and the water sprayer assembly 2 along the circumferential direction; each band 11 is provided with at least two blocking members 12. It can be installed on a car via the band 11, and the blocking member 12 prevents the band 11 from shifting due to vibration during movement after the fuel assembly device of this utility model is installed on the car. The longitudinal section of the blocking member 12 is n-shaped, and the band 11 is located in the open groove of the n-shape, preventing the band 11 from shifting during movement and causing the fuel tank assembly device to loosen or even fall off the car, thus affecting the safety of passengers.

[0037] Further, see Figure 4 To improve the stability of the band 11 within the blocking member 12, the blocking member 12 has at least two protrusions 13 on its inner sidewall facing the band 11. The protrusions 13 apply a clamping force to the band 11 toward the surface of the fuel tank assembly, thereby firmly fixing the part of the band 11 in contact with the fuel tank assembly to the fuel tank assembly. In order to extend the life of the band 11, the longitudinal section of the protrusions 13 is arc-shaped.

[0038] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
