Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a pressurized rapid refueling tank assembly, including a tank body 1, a refueling pipe 2 on the tank body 1, an air bladder groove 8 inside the refueling pipe 2, a corrosion-resistant silicone air bladder 9 inside the air bladder groove 8, the corrosion-resistant silicone air bladder 9 being connected to a miniature air pump 4 via an inflation pipe 5 and to a miniature air pump 6 via an extraction pipe 7; and a tank breather 13, which is connected to the tank body 1 via a tank air pipe 11.

[0023] The oil level sensor body 10 used in this new invention is the CR-606F economic oil level sensor manufactured by Henan Changrun Automation System Co., Ltd.

[0024] In practical use, one end of the fuel nozzle is inserted into the fuel pipe 2. The mini air pump 4 inflates the corrosion-resistant silicone air bag 9 through the air inflator 5, causing the corrosion-resistant silicone air bag 9 to expand. This causes the inner side of the corrosion-resistant silicone air bag 9 to contact one end of the fuel nozzle, thus sealing the fuel pipe 2 and preventing fuel from splashing from the fuel pipe 2 outlet during rapid refueling. The gas in the fuel tank is then expelled through the fuel tank breather 13 and the fuel tank air pipe 11 during refueling, achieving pressure balance within the fuel tank body 1 and facilitating actual use by personnel.

[0025] Example 2

[0026] Based on Embodiment 1, in order to prevent fuel from splashing out from the outlet of the refueling pipe 2 during refueling, a corrosion-resistant silicone airbag 9 is provided. The air extraction pipe 7 provided on the corrosion-resistant silicone airbag 9 passes through the hole opened on the side of the refueling pipe 2 and is fixedly installed on the air extraction hole of the micro air extraction pump 6. The micro air extraction pump 6 is fixedly installed on the upper surface of the fuel tank body 1. Remove the fuel tank cap 3 on the refueling pipe 2 and insert one end of the refueling gun into the refueling pipe 2.

[0027] The inflation tube 5 on the corrosion-resistant silicone airbag 9 passes through the hole on the side of the refueling pipe 2 and is fixedly installed on the inflation port of the micro air pump 4. The micro air pump 4 is fixedly installed on the upper surface of the fuel tank body 1. The micro air pump 4 inflates the corrosion-resistant silicone airbag 9 through the inflation tube 5, causing the corrosion-resistant silicone airbag 9 to expand and the inner side of the corrosion-resistant silicone airbag 9 to contact one end of the refueling nozzle, thereby sealing the refueling pipe 2 and preventing fuel from splashing from the outlet of the refueling pipe 2 during rapid refueling. When the fuel level rises, there is no need to reduce the refueling speed of the refueling nozzle, which can improve the refueling speed throughout the refueling process. In addition, during the entire refueling process, the fuel tank breather 13 and the fuel tank air pipe 11 are used to discharge the gas in the fuel tank during refueling to maintain the air pressure balance inside the fuel tank body 1.

[0028] The airbag groove 8 has an annular groove structure, and a corrosion-resistant silicone airbag 9 is installed inside the airbag groove 8. The corrosion-resistant silicone airbag 9 has a cylindrical structure. In its initial state, the corrosion-resistant silicone airbag 9 is stuck in the airbag groove 8 opened on the inner side of the refueling pipe 2 and is fixedly connected to the refueling pipe 2. The refueling pipe 2 is equipped with a fuel tank cap 3. The operator can observe the oil level in the fuel tank body 1 through the mechanical oil gauge 15. When the tank is almost full, the refueling speed of the refueling nozzle can be reduced in advance. After the oil level sensor body 10 detects that the oil level has reached the preset value, the micro air pump 6 draws the gas in the corrosion-resistant silicone airbag 9 to cause the corrosion-resistant silicone airbag 9 to contract, releasing the seal at the refueling pipe 2. The refueling nozzle can then be removed, and the fuel tank cap 3 can be installed on the refueling pipe 2 for easy use by personnel.

[0029] Example 3

[0030] Based on Embodiment 2, in order to improve the effectiveness of the device, a fuel tank body 1 is provided. A fuel tank air pipe 11 is fixedly installed on the fuel tank body 1. The other end of the fuel tank air pipe 11 is connected to the air hole on the fuel tank breather 13. The other end of the fuel tank breather 13 is connected to the air filter 14 through the connecting pipe 12. The air filter 14 can filter out dust and impurities in the air, which can effectively prevent dust and other impurities from entering the fuel tank body 1 when the fuel tank breather 13 is drawing air to the outside.

[0031] A support frame 16 is fixedly installed on the air filter 14. The support frame 16 is threadedly connected to the fuel tank body 1 by bolts. The fuel tank body 1 is equipped with a fuel level sensor body 10 and a mechanical fuel gauge 15. The air filter 14 is installed on the fuel tank body 1 through the support frame 16. When refueling, the staff can observe the amount of fuel in the fuel tank body 1 through the mechanical fuel gauge 15, which is convenient for refueling personnel to observe and for actual use.

[0032] Working principle: In actual use, the miniature air pump 4 inflates the corrosion-resistant silicone airbag 9 through the air inflator 5, causing the airbag 9 to expand and the inner side of the airbag 9 to contact one end of the fuel nozzle, thus sealing the opening of the fuel nozzle 2. This prevents fuel from splashing from the fuel nozzle 2 outlet during rapid refueling. The fuel tank breather 13 and fuel tank air pipe 11 help to expel the gas in the fuel tank during refueling, maintaining the air pressure balance inside the fuel tank body 1. When the fuel level rises, there is no need to reduce the refueling speed of the fuel nozzle. Only the refueling speed needs to be reduced in the final stage of refueling, which can improve the refueling speed throughout the entire refueling process.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
