Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 to 6, a 360 degrees four-stroke engine can overturn, including engine body 1, engine body 1 includes has dipstick 3, machine oil tank 2 and timing gear 4, and machine oil tank 2 is located engine body 1's bottom, and timing gear 4 is located engine body 1, and machine oil dipstick 3 inserts engine body 1 and stretches into machine oil tank 2 from the extroversion, its characterized in that, the axle connection is provided with one and is used for the frizing 5 that splashes away lubricating oil in machine oil tank 2, and frizing 5 links to each other with timing gear 4 transmission, be equipped with the frizing rail 10 that is used for preventing lubricating oil to flow backward in machine oil tank 2, frizing 5 comprises bar scraper blade 7 on the 6 outer walls of cylinder connecting portion 6 along circumference evenly distributed in cylinder connecting portion 6 with a plurality of cylinder connecting portion.

The oil level gauge 3 is marked with a maximum oil level and a minimum oil level scale, and the lubricating oil level is the position of the lubricating oil level when the engine is placed upright as shown in fig. 1. The highest and lowest positions of the engine oil are determined to ensure that the oil scraping plate 5 can scrape the oil (except for 20 degrees on the left and right of the inverted position in the embodiment) in the process of overturning the engine, and the lubricating oil cannot flow backwards; the sump 2 is designed to turn in all directions with substantially the same penetration of the wiper blade 5 into the oil, while the sump 2 is designed to prevent the reverse flow of oil, i.e., the wiper blade enclosure 10 shown in fig. 1.

The engine runs, the timing gear 4 drives the oil scraping plate 5 to rotate, the oil scraping plate 5 scrapes lubricating oil, the lubricating oil is brought to the timing gear 4 by the oil scraping plate 5, and the lubricating oil is splashed to parts needing lubrication, such as the inner wall of the cylinder, a tappet and the like, by the timing gear 4 due to the high-speed running of the engine. The oil scraping plate 5 is provided with an oil storage chamber 8 and an oil inlet and outlet through hole 9. In the normal working position (except for inversion) of the engine, lubricating oil can enter and exit through the oil inlet and outlet through holes 9 all the time, so that the oil storage chamber 8 of the oil scraping plate 5 is kept full of lubricating oil; when the engine is inverted, the oil scraping plate 5 cannot scrape lubricating oil, and the lubricating oil in the oil storage chamber 8 flows out through the oil inlet and outlet through hole 9 to provide the lubricating oil for a long time for the engine, so that the normal work of the engine is ensured.

When the engine of the embodiment works, the timing gear 4 drives the oil scraping plate 5 to rotate, and the lubricating oil is enabled to be lubricated by the splashing mode through the rotation of the oil scraping plate 5, such as the inner wall of the cylinder, the cam and the tappet. The oil tank 2 structure ensures that lubricating oil cannot flow backwards in all directions in the process of overturning the engine, and ensures that the oil scraping plate 5 can scrape the lubricating oil (the lubricating oil cannot be scraped only under the condition of approaching inversion). The oil scraping plate 5 adopts an oil storage hole design, so that oil in the oil storage hole can gradually flow out even if the oil scraping plate is inverted, and normal working lubrication within 10 minutes is guaranteed.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
