[0035] Electric chainsaws are power tools primarily used for logging and wood processing. With societal development, their applications are becoming increasingly widespread, placing higher demands on their operability. Currently available electric chainsaws tend to accumulate a large amount of sawdust on the inner sidewalls of the end caps when cutting trees, affecting chip removal and cutting efficiency. This typically requires additional tools to clean the sawdust from the end caps, a cumbersome process that reduces work efficiency.
[0036] Figure 1A schematic diagram of the structure of the housing 100 according to an embodiment of the present invention is shown. Figure 2 A partial structural schematic diagram of the housing 100 according to an embodiment of the present invention is shown. For example... Figure 1 and 2 As shown, this utility model proposes a housing 100 and a power tool. The housing 100 of this utility model includes a shell 10 and a chip removal mechanism 20. The shell 10 has a first cavity 11 and a second cavity 12 spaced apart and connected. The second cavity 12 has a chip removal port 121. The chip removal mechanism 20 includes a sliding assembly and a chip removal plate 22 connected to the sliding assembly. The chip removal plate 22 is disposed within the second cavity 12. The sliding assembly includes a sliding plate 211, a portion of which is disposed in the first cavity 11 and can slide relative to the shell 10. When the sliding plate 211 slides relative to the shell 10, it can drive the chip removal plate 22 to move, thereby discharging impurities in the second cavity 12 from the chip removal port 121.
[0037] By using the housing 100 in this technical solution, the sliding member can be moved in the sliding direction, and the chip removal plate 22 can be moved simultaneously. As the chip removal plate 22 moves, the impurities in the second cavity 12 can be agitated and discharged through the chip removal port 121. This reduces the situation where the large amount of impurities in the second cavity 12 affects the normal operation of the housing 100 and the power tool. Compared with the prior art, which requires tools to remove impurities, the housing 100 of this utility model can achieve chip removal by its own sliding, which not only improves convenience but also enhances work efficiency.
[0038] In some embodiments of this utility model, such as Figure 5 As shown, the sliding assembly also includes a driving member connected to the sliding plate 211. The driving member has a driving part 212, which is located outside the housing 10 and is used to drive the sliding plate 211 to reciprocate relative to the housing 10. In this embodiment, the driving part 212 protrudes from the housing 10, making it easy for the operator to hold the driving part 212 and move it along the sliding direction, thereby driving the sliding plate 211 and the chip removal plate 22 to move. Part of the sliding plate 211 is disposed in the first cavity 11 and can move with the movement of the driving part 212. In this embodiment, the first cavity 11 has a third opening on one side along the first direction, through which the sliding part can protrude from the housing 10.
[0039] In some embodiments of this utility model, such as Figure 5As shown, the drive unit 212 is covered with a sliding handle 2121. In this embodiment, the handle 2121 facilitates the operator's gripping and operation of the drive unit 212, and makes it easier for the operator to apply force to the drive unit 212, thus improving convenience.
[0040] In some embodiments of this utility model, such as Figure 1 As shown, the housing 10 is provided with a sliding hole 1411, which extends along the sliding direction of the sliding assembly. The driving part passes through the sliding hole 1411 and can reciprocate along the extending direction of the sliding hole 1411.
[0041] In some embodiments of this utility model, such as Figure 1 As shown, the chip discharge port 121 is disposed on one side of the second cavity 12 along the extending direction of the sliding hole 1411. In this embodiment, the extending direction of the sliding hole 1411 and the disposed direction of the chip discharge port 121 in the second cavity 12 are consistent, which can ensure that the sliding plate 211 drives the chip discharge plate 22 to move in the same direction, thereby improving the transmission efficiency between the sliding plate 211 and the chip discharge plate 22.
[0042] In some embodiments of this utility model, such as Figure 3 As shown, the sliding assembly also includes an elastic connector 23, which is disposed in the first cavity 11. One end of the elastic connector 23 is connected to the outer shell 10, and the other end is connected to the sliding plate 211. In this embodiment, the elastic connector 23 is a spring or other elastic component. The sliding plate 211 is elastically connected to the outer shell 13 through the elastic connector 23, which allows the sliding plate 211 to automatically spring back to its initial position after moving to the end, saving some of the pull force required by the operator and improving work efficiency.
[0043] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figure 3, the outer casing 10 includes a cover plate 14 and a casing body 13. The cover plate 14 covers the outer side of the casing body 13, and a first cavity 11 and a second cavity 12 are formed between the cover plate 14 and the casing body 13. In this embodiment, the outer casing 10 adopts a split connection structure, which facilitates the operator to disassemble the outer casing 10 into the cover plate 14 and the casing body 13, and facilitates the operator to install the sliding plate 211 and the chip removal plate 22 into the first cavity 11 and the second cavity 12, respectively. In addition, when the sliding plate 211 and the chip removal plate 22 malfunction, the operator can also understand the fault information by disassembling the cover plate 14, which improves the efficiency of troubleshooting.
[0044] In some embodiments of this utility model, such as Figure 4As shown, the cover plate 14 includes a bottom plate 141, a side plate 142, and a partition plate 143. The side plate 142 surrounds the circumferential edge of the bottom plate 141, and a receiving cavity is formed between the side plate 142, the outer shell body 13, and the bottom plate 141. The partition plate 143 is located in the receiving cavity and divides the receiving cavity into a first cavity 11 and a second cavity 12. In this embodiment, the partition plate 143 is used to divide the receiving cavity into the first cavity 11 and the second cavity 12, so that the first cavity 11 accommodates the sliding plate 211, and the second cavity 12 accommodates the chip removal plate 22. The chip removal port 121 is provided on the side plate 142 and communicates with the second cavity 12.
[0045] In some embodiments of this utility model, such as Figure 4 As shown, a first opening 1431 is provided on the side of the partition 143 facing away from the bottom plate 141. The chip removal plate 22 is folded towards the sliding plate 211 on the side facing the outer shell body 13 to form a connecting part 221. The connecting part 221 passes through the first opening 1431 and is connected to the sliding plate 211. In this embodiment, the first opening 1431 is used to accommodate the connecting part 221 of the sliding plate 211, and the connecting part 221 can move within the first opening 1431 along the sliding direction of the sliding plate 211. The connecting part 221 abuts against the outer shell body 13 and the partition 143 respectively, which can ensure that during the sliding of the sliding plate 211, the flow of wood chips and other impurities in the second cavity 12 into the first cavity 11 is reduced.
[0046] In some embodiments of this utility model, the second cavity 12 has a second opening on one side along the first direction, and the first direction intersects with the sliding direction of the sliding assembly. In this embodiment, the second cavity 12 is also used to accommodate part of the blade, while another part of the blade extends out of the outer shell 10 through the second opening, thereby completing the corresponding cutting operation.
[0047] This utility model also proposes an electric tool, comprising:
[0048] Housing 100, housing 100 is the housing 100 described above;
[0049] The cutting tool mechanism, part of which is installed in the second cavity 12;
[0050] The drive mechanism is mounted on the housing 100 and is connected to the tool mechanism drive.
[0051] By using the power tool in this embodiment, the cutting mechanism, driven by the drive mechanism, can cut the material to be cut, thereby completing the cutting operation. Moving the sliding member 20 in the sliding direction simultaneously moves the chip removal plate 22. As the chip removal plate 22 moves, it agitates the impurities in the second cavity 12, which are then discharged through the chip removal port 121. This reduces the impact of excessive impurities in the second cavity 12 on the normal operation of the housing 100 and the power tool. Compared to existing technologies that require tools to remove impurities, the housing 100 of this invention can achieve chip removal simply by sliding itself, which not only enhances convenience but also improves work efficiency.
[0052] By using the housing 100 of the power tool in this technical solution, the sliding member 20 can be moved in the sliding direction, which can simultaneously move the chip removal plate 22. As the chip removal plate 22 moves, the impurities in the second cavity 12 can be agitated and discharged through the chip removal port 121. This reduces the situation where the large amount of impurities in the second cavity 12 affects the normal operation of the housing 100 and the power tool. Compared with the prior art, which requires tools to remove impurities, the housing 100 of this utility model can achieve chip removal through its own sliding, which not only improves convenience but also enhances work efficiency.
[0053] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
