Description

Technical Field

[0001] The utility model relates to a fuel injector which is convenient to install. Background Art

[0002] The main function of the injector is to spray precisely measured fuel into the combustion chamber to achieve control of the combustion process. The injection action can be completed in a very short time to meet the changes in the engine's fuel demand. For example, the patent publication number CN217926129U is a car engine injector valve body. By opening the injector body, gasoline flows into the second injection pipe through the first injection pipe, and is injected into the oil storage pipe through the second injection pipe. The first drive turntable and the second drive turntable rotate outside the valve shaft to drive the valve plate body to rotate. The fixed plates at both ends of the valve shaft can prevent the valve shaft from shifting when the valve plate body rotates. After the valve plate body rotates, gasoline flows into the injection port. The pressure at the injection port can be increased through the booster device and the injection hole, so that the gasoline has a better atomization effect when it is sprayed.

[0003] This embodiment can improve the atomization effect of the injector and ensure the normal use of the product, but it has the following defects:

[0004] 1. The oil injection pipe is set up to realize the input of oil. However, when the oil injection pipe is connected to the external pipeline, the oil injection pipe is located in a narrow space and has a high hardness, which is not convenient for installation and connection;

[0005] 2. The atomization effect of the fuel injector can be improved by setting the fuel injection port and the fuel injection hole, but the incompletely burned oil will gather on the fuel injection port and the fuel injection hole, affecting the normal use of the fuel injector. Summary of the invention

[0055] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the valve body 1 is processed, several grooves 10 are added to the outer circle of the tube body to prevent the internal tube body of the product from sliding and being unable to hold during injection molding; the connecting seat 31 is fixedly arranged on the outside of the valve body 1, the mounting seat 32 is movably arranged on the side of the connecting seat 31, the hose 34 is arranged between the connecting seat 31 and the mounting seat 32, and the mounting seat 32 and the connecting seat 31 are fixedly connected at both ends; the side of the mounting seat 32 away from the connecting seat 31 is fixedly connected with an external threaded pipe 33 for realizing connection with an external pipe through the external threaded pipe 33; at the same time, the external threaded pipe 33, the mounting seat 32, the hose 34, the connecting seat 31 and the valve body 1 are interconnected to realize the transmission of oil.

[0056] The external fixing sleeve of the connecting seat 31 is provided with a fixing ring 41, and a fixing block 42 is fixedly connected to the side of the fixing ring 41, and a threaded hole 43 is provided in the center of the fixing block 42; a movable ring 44 is rotatably installed on the outside of the mounting seat 32, and a movable block 45 is slidably provided on the outside of the movable ring 44, and an elastic rod 47 is fixedly connected to the bottom surface of the movable block 45, and the elastic rod 47 can be made of other soft and supporting materials such as rubber or silicone; the bottom end of the elastic member 46 is rotatably installed with a threaded rod 48 through a rotating connection, and the bottom end of the threaded rod 48 is installed in the threaded hole 43 and is threadedly connected to the thread in the threaded hole 43, and the connection component 2 is supported by the connection between the elastic member 46 and the fixed block 42.

[0066] The injection hole 8 on the injection pipe 6 is located in the valve body 1, and oil is input into the oil inlet groove 9. When the injector is working, the magnetic coil 71 is energized. At this time, the magnetic coil 71 generates magnetic force and repels the movable rod, pushing the movable rod to move outward. At the same time, in conjunction with the setting of the oil inlet pipeline, the connecting spring 73 is pulled up, and at this time the movable rod pushes the injection pipe 6 to move outward, the injection hole 8 is located outside the valve body 1, and the oil in the valve body 1 is sprayed; then the magnetic coil 71 is de-energized, and the connecting spring 73 restores its deformation, driving the movable rod and the injection pipe 6 back to their original position. At the same time, the injection hole 8 is located in the valve body 1 to prevent impurities generated during the combustion of the oil from accumulating on the injection hole 8 and affecting the normal use of the injector.
