[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] Figures 1-5 As shown, a handheld electric chainsaw with lubrication function includes a body 1 and chain plates 11 fixed on the body 1. A chain 10 is provided on the chain plates 11. A protective cover 2 is fixedly connected to the body 1 above the chain plates 11, which can block some of the cutting debris. Several nozzles 12 are fixedly connected inside the protective cover 2. There is a gap between the nozzles 12 and the chain 10, which facilitates the even spraying of lubricating oil on the surface of the chain plates 11 and the chain 10. An oil tank is fixedly connected above the protective cover 2. A connecting groove 13 for connecting the oil tank and the nozzles 12 is opened inside the protective cover 2. When the nozzles 12 are turned on, the lubricating oil in the oil tank enters the nozzles 12 through the connecting groove 13.

[0026] Figures 3-5 As shown, when it is necessary to lubricate the chain 10 and chain link 11, the nozzle 12 is activated. At this time, the lubricating oil in the oil tank enters the nozzle 12 through the connecting groove 13 and is evenly sprayed onto the surface of the chain link 11 and chain 10 through the nozzle 12, thereby completing the lubrication of the chain link 11 and chain 10. This design enables the lubrication work to be completed automatically, reduces labor, and ensures even oil application, thus improving the lubrication effect.

[0027] Figures 3-5 As shown, an oil inlet 4 is provided on the top surface of the oil tank. A piston 3 is detachably connected inside the oil inlet 4. Therefore, when the lubricating oil in the oil tank is insufficient, the oil inlet 4 can be opened by removing the piston 3, which facilitates the addition of lubricating oil.

[0028] Figures 3-5 As shown, the protective cover 2 is detachably connected to a brush located below the nozzle 12. The brush abuts against the chain 10 and chain link 11. When oiling is required, the nozzle 12 sprays lubricating oil, and the brush adheres to the lubricating oil and applies it to the chain 10. The brush includes a mounting plate 5 and a brush head 8 fixedly connected to the free end of the mounting plate 5. The mounting plate 5 is detachably connected to the protective cover 2, and the brush head 8 abuts against the chain link 11 and the chain 10.

[0029] Figures 3-5 As shown, when the nozzle 12 sprays lubricating oil evenly onto the surface of the chain link 11 and the chain 10, the brush head 8, as the chain 10 rotates, further applies lubricating oil to the surface of the chain 10 and the chain link 11 and into the gaps, thereby improving the lubrication effect and further enhancing the lubrication effect.

[0030] Figures 3-5 As shown, a groove 7 is provided on the inner wall of the protective cover 2. The mounting plate 5 is fixedly connected to a sliding plate 6 located in the groove 7 at the end away from the brush head 8. One end of the sliding plate 6 extends outside the groove 7. Since the brush head 8 is prone to wear due to long-term friction with the chain 10 and chain piece 11, the sliding plate 6, the mounting plate 5 and the brush head 8 can be disassembled and replaced together by pulling the end of the sliding plate 6 located outside the groove 7. This design facilitates the replacement of the brush head 8.

[0031] Figures 3-5 As shown, a slot is provided on the slide plate 6, and a block is fixedly connected to the inner side wall of the slide groove 7. When the slide plate 6 is in the slide groove 7, the block is engaged in the slot. Therefore, when the slide plate 6 is slid into the slide groove 7, the block is engaged in the slot, thereby fixing the slide plate 6, the mounting plate 5 and the brush head 8, thus preventing the brush head 8 from shifting when the chain 10 rotates.

[0032] Figures 3-5 As shown, a storage tank 9 is formed between the mounting plate 5 and the inner wall of the protective cover 2. The angle of the storage tank 9 is less than 90°. Therefore, when the nozzle 12 sprays lubricating oil onto the chain link 11 and the surface of the chain link 11, some of the lubricating oil falls into the storage tank 9 due to gravity and is collected. The excess lubricating oil on the surface of the chain link 11 and the chain 10 is collected by the inclined surface of the mounting plate 5 into the storage tank 9, thus avoiding excess lubricating oil dripping and affecting environmental hygiene.
