[0002] An injector is a precision device with very high machining accuracy, requiring a large dynamic flow range, strong anti-blocking and anti-pollution capabilities, and good atomization performance. The injector receives the fuel injection pulse signal sent by the ECU and precisely controls the fuel injection volume. The spray characteristics of the injector include atomization particle size, oil mist distribution, oil spray direction, range, and diffusion cone angle, etc. These characteristics should meet the requirements of the diesel engine combustion system to enable the formation and perfect combustion of the air-fuel mixture and obtain higher power and thermal efficiency.

[0003] During the use of the injector, a fuel injection pipe is needed to facilitate the connection between the drive motor and the nozzle. To ensure the quality of gasoline spraying, a filtering device needs to be installed inside the pipe. After long-term use, the filtering device will be blocked by oil stains or impurities, resulting in a small fuel injection volume from the nozzle. In severe cases, the nozzle will not inject oil at all, making it difficult for gasoline to enter the cylinder.

[0004] Therefore, a new solution is needed to solve this problem. Content of the Utility Model

[0005] In view of the above background technique, after long-term use of the existing equipment, the filtering device will be blocked by oil stains or impurities, resulting in a small fuel injection volume from the nozzle. In severe cases, the pipe will not pass oil at all, making it difficult for gasoline to enter the cylinder.

[0006] An anti-blocking fuel injection pipe for a drive motor disclosed by the utility model includes a T-shaped pipe and connecting pipes arranged at equal distances. Below each connecting pipe, there is a spray pipe and a rotating pipe. A filter screen is installed on the inner wall of each spray pipe. Connecting rings are fixedly connected to the outer surfaces of each connecting pipe and spray pipe. The outer surface of each rotating pipe is rotatably connected to the corresponding two connecting rings. A scraper is arranged inside each rotating pipe. A connecting column is fixedly connected to the outer surface of each scraper. One end of each connecting column away from the corresponding scraper is fixedly connected to the corresponding rotating pipe. The bottom surface of each scraper is in contact with the corresponding filter screen.

[0007] Furthermore, a side pipe is fixedly communicated inside each connecting pipe, and a plug is threadedly connected to the upper end of each side pipe.

[0008] Furthermore, an oil inlet pipe is fixedly communicated with the upper end of the T-shaped pipe, and the lower end of the oil inlet pipe is communicated with the T-shaped pipe.

[0009] Furthermore, two oil distribution pipes are fixedly connected inside each of the T-shaped pipes, and an oil supply pipe is fixedly communicated inside each of the oil distribution pipes.

[0010] Furthermore, an electromagnetic valve is fixedly installed at the lower end of each of the oil supply pipes, and the lower end of each electromagnetic valve is communicated with a corresponding connecting pipe.

[0011] Furthermore, fixing rings are fixedly connected to the outer surfaces of each of the oil distribution pipes and the spray pipes, fixing plates are fixedly connected to the outer surfaces of each of the fixing rings, and fixing holes are formed inside each of the fixing plates.

[0012] Furthermore, a nozzle is fixedly communicated with the lower end of each of the spray pipes, and each nozzle adopts a single-hole fuel injector.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing components such as a filter screen, a connecting ring, a rotating pipe, and a scraping plate, when using the device, when the nozzle is blocked, by controlling the rotation of the rotating ring in the connecting ring, when the rotating ring rotates, it will drive the scraping plate to rotate on the filter screen through the connecting column. When the scraping plate rotates on the filter screen, it will scrape and clean the filter screen, and by cleaning the filter screen, the problem of blockage of the fuel injection pipe is avoided, so as to achieve the effect that the device can avoid blockage inside the fuel injection pipe according to requirements.

[0015] 2. By providing components such as a rotating pipe, a connecting pipe, a side pipe, and a plug, when using the device, after the scraping plate cleans the filter screen, to avoid the filter screen being blocked by dust again, the electromagnetic valve can be closed and the plug can be opened.
