[0037] The deflector for refueling provided by the utility model adopts the above-mentioned structure. When the oil just comes out, it is blocked by the spoiler structure 720, thereby slowing down the speed of the oil passing through the outlet end of the guide channel 710, which helps to control the flow rate, reduce the impact force and liquid splashing when the oil is sprayed out, and improve the safety of operation. It can make the fluid more evenly distributed and flow in the guide channel 710, avoid unevenness when the fluid flows out, ensure that the fluid flow near the outlet is more stable and controllable, and increase the service life of the deflector and the fuel tank, which helps to reduce energy consumption and reduce fluid waste, and is in line with the concept of energy conservation and environmental protection.

[0038] It can also be understood that, in the embodiment of the present invention, the spoiler structure 720 is a spoiler convex rib connected to the guide body 700, and the spoiler convex rib is arranged to protrude toward the center line of the guide channel 710. With the above structure, the spoiler structure 720 is present, and when the oil just comes out, it is blocked by the spoiler structure 720, thereby slowing down the speed of the fluid passing through the outlet end of the guide channel 710, ensuring that the fluid flow near the outlet is more stable and controllable, and can effectively reduce the splashing and splashing phenomenon when the fluid flows out, which helps to reduce energy consumption and reduce the waste of fluid, and is in line with the concept of energy saving and environmental protection.

[0039] Specifically, refer to Figure 1 and Figure 2 In the embodiment of the present invention, there is a gap between the lower end surface of the spoiler rib and the lower end surface of the outlet end of the corresponding guide channel 710 on the guide body 700. Before entering the fuel tank, the fuel can be gathered in the gap area and flow stably into the fuel tank.

[0040] Specifically, in the embodiment of the present invention, a side wall of the spoiler rib facing the center line of the guide channel 710 is parallel to the center line of the guide channel 710, which is convenient for processing and manufacturing and also convenient for oil flow.

[0041] Specifically, in the embodiment of the present invention, the spoiler rib and the deflector are an integrated structure, and the spoiler rib can be directly manufactured as a part of the deflector, which simplifies the manufacturing and installation process, reduces the number of parts and assembly steps, and saves additional materials and manufacturing costs.

[0042] Specifically, in the embodiment of the present invention, there are multiple groups of spoiler structures 720, which are spaced apart on the inner wall of the guide channel 710, which helps to disperse the pressure of the oil fluid, improve energy efficiency, and improve flow stability and controllability.

[0043] Specifically, refer to Figure 1 and Figure 2 In the embodiment of the utility model, the inner diameter of the flow guide channel 710 gradually decreases along the first direction from the insertion end to the outlet end. The larger inlet opening can facilitate the insertion of the fueling gun head, especially at the beginning of the insertion. The larger opening can reduce the requirement for the alignment accuracy of the fueling gun, making it easier for the operator to correctly insert the fueling gun into the flow guide channel 710 of the flow guide body 700.

[0044] Specifically, in the embodiment of the present invention, the inner wall of the flow guide channel 710 includes a first straight section 711, an inclined guide section 712, and a second straight section 713, and the first straight section 711, the inclined guide section 712, and the second straight section 713 are sequentially arranged along the length direction of the flow guide. Through the above structure, the first straight section 711 can guide the fluid into the flow guide channel 710, the inclined guide section 712 can guide the fluid to the downstream direction and accelerate the flow speed of the fluid, and the second straight section 713 is used to stabilize the flow of the fluid, so that it forms a stable flow state inside the flow guide.

[0045] It should be noted that, refer to Figures 3 to 6 In an embodiment of the utility model, the main cover unit includes the above-mentioned deflector and a main cover shell 600, the main cover shell 600 is connected to the deflector body 700, the main cover shell 600 is provided with a main cover channel 610, the main cover channel 610 is connected with the deflector channel 710 to form a main cover chamber, wherein the main cover shell 600 is provided with a valve structure 800 for opening or closing the main cover channel 610.

[0046] It is understandable that, referring to Figure 3 and Figure 4 In an embodiment of the utility model, the main cover shell 600 and the guide body 700700 are fixed separately, and an insertion port 620 is provided at one end of the main cover shell 600 relative to the guide body 700. The insertion port 620 corresponds to the spoiler structure 720 one by one and is plug-in matched to further limit the rotation of the main cover shell 600 relative to the guide body 700, thereby improving the stability of the main cover unit.

[0047] It should also be noted that, referring to Figure 5 and Figure 6 In the embodiment of the present invention, the auxiliary gate unit is provided with an auxiliary gate chamber 110 , and the auxiliary gate chamber 110 is connected to and communicated with the main cover passage 610 .

The gate structure 200 is fixedly arranged inside the auxiliary gate chamber 110. Part of the gate structure 200 is fixedly matched with the auxiliary gate housing 100; the refueling gun guide rail 300 is used to guide the refueling gun to move. The refueling gun guide rail 300 is fixedly arranged on the auxiliary gate. Inside the door chamber 110, the fueling gun guide rail 300 is located on one side of the gate structure 200, and part of the structure of the fueling gun guide rail 300 is fixedly matched with the auxiliary gate housing 100; in a first direction, one end of the gate structure 200 abuts against an inner wall at one end of the auxiliary gate chamber 110, and the other end of the gate structure 200 abuts against one end of the fueling gun guide rail 300; wherein, when the gate structure 200 is subjected to the pushing force of the fueling gun, the first inlet is opened, and the opening direction of the gate structure 200 is toward the location of the first outlet; after the gate structure 200 is out of contact with the fueling gun, the first inlet is closed, and the closing direction of the gate structure 200 is toward the location of the first inlet.

[0049] Through the above structure, there is no need to unscrew the auxiliary gate unit when refueling, and the refueling gun can be directly inserted, and the gate structure 200 is pushed by the refueling gun to open the first inlet, so that the refueling gun can be inserted into the auxiliary gate chamber 110, the gate structure 200 and the refueling gun guide rail 300 to realize the refueling operation.

Through the specially designed drain port 120 and drain channel 310, a small amount of water flowing in from the gap between the auxiliary gate housing 100 and the gate structure 200 can be discharged from the drain port 120, avoiding the decrease in the sealing performance of the auxiliary gate unit and the partial damage of the main cover unit caused by the insertion of the refueling gun after freezing; and because there are certain sealing requirements for the auxiliary gate unit and the entire refueling device during refueling, a sealing mechanism 400 is provided to seal the drain channel 310 and the drain port 120, so as to achieve sealed refueling while also being able to cope with steam reflux type refueling guns.
