For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0027] See also Figure 1 This embodiment discloses an engine lubrication assembly 10, which is fixed to an engine 100. The engine 100 includes a casing 1, a reed valve mounting base 2 fixed to the casing 1, and a connecting pipe 3 fixed to the reed valve mounting base 2. The engine lubrication assembly 10 includes a bracket 5, an electronic oil pump 6, an oil delivery pipe 7, and an oil nozzle 8. A mounting bracket 21 is provided on the sidewall of the reed valve mounting base 2, and a reed valve 22 is installed within the reed valve mounting base 2. A mounting base 31 is provided on the connecting pipe 3.

[0028] The bracket 5 is fixed to the side of the reed valve mounting seat 2, the electronic oil pump 6 is installed in the bracket 5, and the oil nozzle 8 is fixed on the connecting pipe 3. One end of the oil delivery pipe 7 is connected to the electronic oil pump 6, and the other end is connected to the oil nozzle 8.

[0029] The bracket 5 includes an arc-shaped locking section 51 and two interlocking fixing sections 52 at either end of the locking section 51. The fixing sections 52 include a first fixing section 521 and a second fixing section 522. The first fixing section 521 is positioned in contact with the reed valve mounting seat 2, while the second fixing section 522 is positioned in contact with the first fixing section 521. The first fixing section 521 is tangentially disposed along one end of the locking section 51, while the second fixing section 522 is bent from the other end of the locking section 51, with the bend being rounded.

[0030] The electronic oil pump 6 is inserted into the locking section 51. A rubber sleeve 9 is positioned between the electronic oil pump 6 and the locking section 51, securely securing the electronic oil pump 6 to the bracket 5 and preventing it from falling out of the locking section 51. Bolts pass through the second fixing section 522 and the first fixing section 521 and secure to the mounting bracket 21, thereby securing the bracket 5 to the reed valve mounting base 2. This fixing method significantly saves installation space and meets the design concept of a miniaturized and lightweight engine.

[0031] The oil nozzle 8 includes a quick-connect connector 81 and an oil injection pipe 82. The quick-connect connector 81 includes a fixing portion 811 inserted and fixed in the mounting seat 31, a limiting portion 812 located at the end of the fixing portion 811 and protruding radially outward, and a connecting portion 813 for the oil delivery pipe 7 to be sleeved and fixed. The limiting portion 812 is located between the fixing portion 811 and the connecting portion 813, and the limiting portion 812 is supported on the upper surface of the mounting seat 31. A through hole 814 is provided in the quick-connect connector 81, which passes through the connecting portion 813, the limiting portion 812, and the fixing portion 811. A plug-in hole 815 is provided in the fixing portion 811 and is connected to the through hole 814. The plug-in hole 815 is coaxially arranged with the through hole 814, and the diameter of the plug-in hole 815 is larger than the diameter of the through hole 814.

[0032] The connection between the insertion hole 815 and the through hole 814 forms a stepped surface 816. The oil injection pipe 82 is inserted into the insertion hole 815 and abuts against the stepped surface 816. One end of the oil injection pipe 82 is inserted into the insertion hole 815, while the other end is constricted, including a funnel-shaped constriction 821. The provision of constriction 821 ensures that the oil mist drips more accurately onto the reed valve 22. The operation of the reed valve 22 drives the atomization of the engine oil, thereby improving the overall lubrication effect of the lubricating oil.

[0033] The ECU collects signals from the speed and temperature sensors, analyzes the engine's real-time operating conditions, and controls the electronic oil pump 6, providing real-time control over the injection volume and flow rate. Compared to traditional forced lubrication with constant pressure and fixed quantity, this improves lubricant utilization, more precisely controls injection volume, and reduces the risk of over-injection leading to overflow and "oil burning," among other risks. Furthermore, the oil nozzle 8 features a simpler structure and oil circuitry, making it more lightweight and cost-effective.

[0034] In order to achieve a good atomization effect, the oil nozzle 8 is arranged behind the throttle 4 and in front of the reed valve 22. The oil enters the crankcase together with the intake air. The electronic oil pump 6 delivers the oil in the oil tank into the engine intake duct through the oil pipe 7, the quick-connect connector 81 and the oil injection pipe 82. The oil is then broken up into oil mist through the high-frequency opening and closing action of the reed valve 22. Finally, the oil mist is mixed with the air coming from the intake duct to form an oil-air mixture that fills the crankcase, thereby achieving lubrication of all components in the crankcase.

[0035] This embodiment also discloses an engine 100 , which includes the above-mentioned engine lubrication assembly 10 .

[0036] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments described above without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention that fall within the scope of the appended claims and their equivalents.
