Description

Technical Field

[0001] This utility model relates to the field of electric chainsaw technology, to the chip removal of electric chainsaws, and particularly to the side chip removal structure of electric chainsaws. Background Technology

[0002] An electric chainsaw is an electric tool that uses electricity to drive the high-speed movement of the chain cutting teeth to cut wood. The chain is mounted on a guide plate and is driven by an engine or motor. The movement of the chain transmits cutting force to the wood, thereby achieving the cutting. Electric chainsaws are generally suitable for light work, such as home gardening and pruning branches.

[0003] In some patents, such as the handheld electric chainsaw with authorization announcement CN218218425U, or an electric chainsaw with authorization announcement number CN211090786U, or an electric chainsaw chip removal structure and assembly method with authorization announcement CN104493926B, in order to prevent the wood chips cut by the electric chainsaw from accumulating between the main unit and the side cover during operation, a chip removal port is opened at the lower or rear lower position of the side cover, so as to facilitate the discharge of wood chips accumulated between the side cover and the main unit during operation.

[0004] The chip ejection port allows the chainsaw to cut wood and eject wood chips simultaneously during operation. However, this design also makes the chainsaw less suitable for cutting branches at higher positions, especially when the chainsaw needs to be held high. As the chips are ejected from the chip ejection port, they fall directly into the air and scatter onto the operator's hands or face, affecting the operator's vision and work efficiency, thus impacting the user experience of the chainsaw.

[0007] The chip discharge port is provided with a side opening, and a rear baffle and a bottom baffle are provided on one side of the side cover or the main unit. The rear baffle and the bottom baffle form an angle of less than 180°. The rear baffle and the bottom baffle protrude from the side cover, and the chip discharge port is located in the angle.

[0008] A further preferred embodiment of this utility model is that the rear stop and the bottom stop are connected to form an L-shaped or V-shaped structure.

[0009] A further preferred embodiment of this utility model is that the rear stop or bottom stop has an L-shaped or V-shaped structure, and the connected rear stop and bottom stop have a C-shaped structure.

[0010] A further preferred embodiment of this utility model is: an outer stop is connected between the rear stop and the bottom stop, and the outer stop is disposed on the side offset from the side cover.

[0011] A further preferred embodiment of this utility model is that the chip discharge port is set at the lower rear position of the side cover or at the side opening.

[0012] Another technical solution of this utility model is: a side chip removal structure of an electric chainsaw, including a main unit with an engine or motor inside, a guide plate installed on one side of the main unit, a saw chain installed on the guide plate and capable of being driven by the engine or motor, and a side cover installed on one side of the main unit and covering part of the guide plate and the saw chain, wherein a chip removal port is provided on the side cover.

[0013] The chip discharge port is provided with a side opening, and a protruding chip baffle is provided on one side of the side cover or the main unit. The chip baffle has an arc-shaped structure, and the chip discharge port is located at the position where the chip baffle is arc-shaped and recessed inward.

[0014] A further preferred embodiment of this utility model is: the chip-blocking part is provided with an outer baffle, which is located on the side offset from the side cover.

[0015] A further preferred embodiment of this utility model is that the chip discharge port is set at the lower rear position of the side cover or at the side opening.

[0016] Another technical solution of this utility model is: a side chip removal structure of an electric chainsaw, including a main unit with an engine or motor inside, a guide plate installed on one side of the main unit, a saw chain installed on the guide plate and capable of being driven by the engine or motor, and a side cover installed on one side of the main unit and covering part of the guide plate and the saw chain, wherein a chip removal port is provided on the side cover.

[0017] The chip discharge port is provided with a side opening, and the side cover is provided with a protruding chip blocking part. The chip blocking part has a tubular structure, and the chip discharge port is located inside the chip blocking part.

[0018] A further preferred embodiment of this utility model is that the chip discharge port is provided as a side opening on the side cover.
