Description

Technical Field

[0001] This utility model belongs to the field of fuel nozzle technology, and specifically relates to a fuel nozzle cleaning device. Background Technology

[0002] The fuel injector is the core component of the fuel injection system. Its function is to deliver high-pressure fuel into the engine combustion chamber or intake manifold with precise injection quantity, atomization pattern, and injection timing. It consists of precision-machined nozzles, solenoid valves (electronic fuel injection systems) or mechanical control mechanisms (mechanical fuel injection systems), fuel passages, etc., and its opening and closing are controlled by the ECU or mechanical devices. A good fuel injector ensures that the fuel is fully atomized and mixed evenly with air, thereby improving combustion efficiency, reducing emissions, and optimizing engine power performance.

[0003] Fuel injectors are prone to clogging after a period of use, requiring disassembly and cleaning. However, due to their intricate internal structure, conventional cleaning methods often fail to completely remove residues, resulting in continued impact on injection accuracy and performance even after reinstallation.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example

[0023] Reference Figure 1-2 This is an embodiment of the present invention, which provides a fuel nozzle cleaning device, including,

[0024] The spraying mechanism 100 includes a nozzle component 110, a connecting pipe 120 disposed on one side of the nozzle component 110, and two fixing clamps 130 for clamping and fixing the nozzle component 110.

[0025] The cleaning mechanism 200 includes a sealing gasket 210 for fitting the water outlet end of the nozzle 110, and a liquid guide tube 220 that communicates with the sealing gasket 210 and is used to backwash the nozzle 110.

[0026] In this process, the cleaning fluid is pumped into the nozzle component 110 by the cooperation between the sealing gasket 210 and the liquid guide tube 220, forming a backwashing effect. This solves the problem that traditional cleaning methods cannot thoroughly clean the inside of the nozzle component 110, thus improving the cleaning effect.

[0027] Specifically, the nozzle component 110 includes a metal housing 111, a fixing screw 112 threaded inside the metal housing 111, a rotating groove 113 formed inside the metal housing 111, an atomizing plate 114 disposed inside the metal housing 111, and a filter screen 115 fixedly installed inside the connecting pipe 120 for filtration.

[0028] Furthermore, the spraying mechanism 100 also includes a loosening wrench 140 for loosening the fixing screw 112, the size of which is adapted to the size of the fixing screw 112.

[0029] The wrench 140 is used to loosen the fixing screw 112 by one turn to facilitate backwashing of the inside of the metal casing 111.

[0030] Preferably, the side of the sealing gasket 210 that contacts the nozzle element 110 fits the outer surface of the nozzle element 110.

[0031] Specifically, by fitting the side of the sealing gasket 210 that contacts the nozzle component 110 with the outer surface of the nozzle component 110, the tightness of the fit between the sealing gasket 210 and the surface of the nozzle component 110 is improved, thereby enhancing the sealing performance at the connection point, preventing pressure leakage, and improving the backwashing effect on the nozzle component 110.

[0032] Furthermore, one end of the connecting pipe 120 is threaded onto the inside of the metal casing 111.

[0033] One end of the connecting pipe 120 is threaded onto the inside of the metal housing 111 to facilitate the removal of the filter screen 115 from the metal housing 111 and to facilitate backwashing of the inside of the metal housing 111.

[0034] Furthermore, the other end of the liquid guide tube 220 is equipped with a high-pressure pump for high-speed delivery of cleaning fluid.

[0035] A high-pressure pump is used to pump the cleaning fluid out of the container and flow it into the interior of the metal casing 111 at high speed to backwash and clean its interior.

[0036] In use, the connecting pipe 120 is detached from one side of the metal housing 111, and the nozzle 150 is disassembled. The nozzle 110 is clamped and fixed using two clamping calipers 130. The disassembly wrench 140 is moved forward and the end of the disassembly wrench 140 is inserted into the inside of the fixing screw 112. After loosening the fixing screw 112 by one turn, the sealing gasket 210 is pressed against the surface of the nozzle 110. The high-pressure pump is started, so that high-speed cleaning fluid flows out of the liquid guide tube 220 to backwash the inside of the nozzle 110. After the rinsing is completed, the fixing screw 112 is tightened again with the disassembly wrench 140, and then the connecting pipe 120 is threaded onto one side of the nozzle 110.

[0037] In summary, by using the cooperation between the sealing gasket 210 and the liquid guide tube 220, the cleaning fluid is pumped into the nozzle component 110 by a high-pressure pump, forming a backwashing effect. This solves the problem that traditional cleaning methods cannot thoroughly clean the inside of the nozzle component 110, thus improving the cleaning effect.
