TECHNICAL FIELD
[0001] The utility model relates to the technical field of electric chain saws, in particular to an automatic oil supply device of electric chain saw. BACKGROUND
[0002] With the development of forestry, landscaping and construction industries, electric chain saws, as a kind of efficient and convenient cutting tool, have been widely used. However, there are many inconveniences in the oil supply process of traditional electric chain saws. On the one hand, manual oiling is not only cumbersome to operate, but also prone to insufficient or excessive lubricating oil due to inaccurate oiling amount, thereby affecting the service life and cutting efficiency of the saw chain. On the other hand, during long-time or high-intensity operation, manual oiling is difficult to keep up with the situation, which may cause the saw chain to dry and grind, leading to equipment failure and even safety accidents. In addition, the traditional oil supply method may also cause environmental pollution due to uneven distribution of lubricating oil. Therefore, it is of great significance to develop a device that can automatically, accurately and uniformly supply oil to improve the performance of electric chain saws, prolong the service life of the equipment, reduce the use cost and protect the environment.
[0003] In the disclosed Chinese patent application with publication number CN219968252U and patent name "Oil supply device of hand-held cordless chain saw", the prior art lubricates the chain by driving the sliding plate and the moving cover with the telescopic rod to make the oil outlet not be closed, and the lubricating oil falls from the oil tank into the chain to lubricate the chain. After lubrication, the telescopic rod drives the sliding plate and the moving cover to return to the original position until the sliding plate contacts the limiting plate, at which time the oil outlet is completely covered by the moving cover. Although this prior art can lubricate the chain, it has certain limitations in specific implementation. The prior art requires separate control of the telescopic rod, and the operator may forget to turn on the telescopic rod during the use of the chain saw, thereby failing to apply lubricating oil to the chain and failing to timely oil the chain of the chain saw.
