Description

Technical Field

[0001] This utility model relates to the field of electric circular saw technology, specifically to an electric circular saw that facilitates the cleaning of dust and debris. Background Technology

[0002] The circular saw is a common power tool widely used in many fields such as wood processing, construction and decoration, and garden pruning. With its high-speed rotating saw blade, it can cut materials quickly and accurately, greatly improving work efficiency. It is one of the essential tools for many practitioners. However, when operating a circular saw to cut materials, cutting wood will produce sawdust, and cutting plastics will produce corresponding debris or dust. If these debris are not cleaned up in time, they will affect the cleanliness of the working environment and the quality of subsequent cuts.

[0003] Existing circular saws have some shortcomings in cleaning dust. Circular saws can only clean one side of the saw blade or do not have a cleaning structure at all, which makes it very inconvenient to clean dust. When only one side of the saw blade can be cleaned, dust will gradually accumulate on the other side, affecting the cutting effect and service life of the saw blade.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an electric circular saw that facilitates the cleaning of dust and debris, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An electric circular saw for easy cleaning of dust includes an electric circular saw housing, a first processing component and a second processing component disposed on the electric circular saw housing, a drive structure disposed on the electric circular saw housing, and a circular saw disposed on the drive structure. The first processing component includes a drive component and a cleaning component.

[0008] Furthermore, to better ensure the drive adjustment effect, the drive component includes a motor, which is mounted on the outside of the electric circular saw housing via a mounting base. The output shaft of the motor extends into the inside of the electric circular saw housing and is equipped with a threaded rod via a coupling. An adjustment block is threadedly connected to the threaded rod.

[0009] Furthermore, to better ensure the adjustment effect, an adjustment plate is symmetrically connected to the adjustment block. One end of the adjustment plate is connected to a movable seat, and one end of the movable seat is equipped with an adjustment plate. The adjustment plates are located on both sides of the circular saw, and a telescopic rod and a connecting pipe are provided between the adjustment plates.

[0010] Furthermore, in order to better ensure the cleaning effect of the circular saw, the cleaning components include a cleaning brush, which is set on one side of the adjustment plate two and contacts one side of the circular saw. The adjustment plate two has a conveying chamber one inside, and a connecting pipe is connected to the conveying chamber one. The conveying chamber one is connected to a conveying pipe, and one end of the conveying pipe is connected to a conveying pump, which is fixedly set on one side of the electric circular saw shell.

[0011] Furthermore, in order to better ensure the gas delivery effect, multiple cleaning holes are provided on one side of the regulating plate 2, and a one-way valve 1 is installed inside the cleaning hole.

[0012] Furthermore, in order to better ensure the cleaning effect of the inner wall of the electric circular saw shell, the second processing component includes a cleaning cover, which is symmetrically arranged on both sides of the adjustment plate two. The cleaning cover has a conveying chamber two inside, and the conveying chamber two is connected to the conveying chamber one. One-way valves two are connected at equal intervals on the conveying chamber two.

[0013] Furthermore, a control switch is installed on the outer wall of the electric circular saw casing.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting the first processing component, when the motor drives the circular saw to rotate, the brush can be used to clean the surface of the circular saw in all directions, effectively removing the dust adhering to the saw blade. At the same time, the conveying pump, conveying pipe and conveying chamber work together to deliver the cleaned dust to the designated position in a timely manner, thereby avoiding the dust from affecting the cutting accuracy and the sharpness of the saw blade, and significantly improving the cutting quality and the service life of the circular saw.

[0016] (2) By setting up a second processing component, the cleaned-up dust can be effectively collected and processed. On the basis of the first processing component cleaning the circular saw, the inner wall of the electric circular saw shell can be further cleaned. The second conveying chamber is connected to the first conveying chamber, and the second conveying chamber is connected with one-way valves at equal intervals. This allows the dust to be conveyed in an orderly manner. At the same time, the one-way valves can also prevent the dust from flowing back, ensuring the efficiency and effect of dust cleaning.

The adjusting plate 8 is located on both sides of the circular saw 22. A telescopic rod 9 and a connecting pipe 10 are provided between the adjusting plates 28. The connecting pipe 10 is an adjustable telescopic pipe to ensure the guiding effect of the movement of the adjusting plate 28 and to ensure the gas delivery effect.

[0030] The cleaning components include a cleaning brush 11 for cleaning both sides of the circular saw. The cleaning brush 11 is located on one side of the adjusting plate 2 8 and contacts one side of the circular saw 22. The adjusting plate 2 8 has a conveying chamber 12 inside, and a connecting pipe 10 is connected to the conveying chamber 12. The conveying chamber 12 is connected to a conveying pipe 13, which is an adjustable telescopic pipe. One end of the conveying pipe 13 is connected to a conveying pump 14. In actual use, the input end of the conveying pump 14 is equipped with a filter structure (not detailed in the figure). (As shown), it is used to filter the incoming gas.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In summary, with the help of the above-mentioned technical solution of this utility model, when the electric circular saw is working, the motor 20 starts, and its output shaft drives the threaded rod 4 to rotate. The adjusting block 5 threaded on the threaded rod 4 moves along the axial direction of the threaded rod 4 under the action of the thread. The movement of the adjusting block 5 causes the adjusting plate 6 to move accordingly. One end of the adjusting plate 6 is connected to the movable seat 7, and the other end of the movable seat 7 is provided with the adjusting plate 8. The adjusting plate 8 is set on both sides of the circular saw 22. As the adjusting block 5 moves, the telescopic rod 9 between the adjusting plates 28 moves in a telescopic motion. At the same time, the cleaning brush 11 provided on the adjusting plate 28 contacts the surface of the circular saw 22. During the high-speed rotation of the circular saw 22, the cleaning brush 11 cleans the surface of the circular saw 22. The brush 11 thoroughly cleans the surface of the circular saw 22, effectively removing dust adhering to the saw blade. The dust falls off, and then the conveying pump 14 starts, sending filtered gas through the conveying pipe 13 into the conveying chamber 12. The gas is then diverted to the conveying chamber 27, and the filtered gas is output through the one-way valve 15 and one-way valve 28. This cleans the inner wall of the electric circular saw housing 1 and the circular saw 22, ensuring that the dust is conveyed in an orderly manner and preventing backflow. This ensures efficient and effective dust collection, avoids affecting cutting accuracy and saw blade sharpness, and thus improves cutting quality and the service life of the circular saw.

[0035] The outer wall of the electric circular saw housing 1 is equipped with a control switch 19, which is used to control the working status of the entire electric circular saw, including the start and stop of the motor 20 and the conveying pump 14.
