[0027] Please refer to Figures 1 to 2 The circular saw blade cover provided by the present invention includes a saw blade cover shell 10, an opening and closing door 11, a first mesh plate 20, a second mesh plate 21, a third mesh plate 22 and a dust outlet pipe 13; the opening and closing door 11 is arranged on the saw blade cover shell 10, and the opening and closing door 11 is hinged to the saw blade cover shell 10, and the opening and closing door 11 and the saw blade cover shell 10 form a rectangular cover structure with an open bottom; the first mesh plate 20, the second mesh plate 21 and the third mesh plate 22 are fixedly arranged in the saw blade cover shell 10, and the first mesh plate 20, the second mesh plate 21 and the third mesh plate 22 form a dust collecting chamber 12 with the saw blade cover shell 10; the dust outlet pipe 13 is arranged on the saw blade cover shell 10, one end of the dust outlet pipe 13 is connected to the dust collecting chamber 12, and the other end of the dust outlet pipe 13 is used to be connected to the dust suction fan.

[0028] During use, the circular saw blade cover is positioned outside the saw blade, with the saw blade at least partially extending from the bottom opening of the circular saw blade cover, facilitating cutting operations. The first, second, and third mesh plates 20, 21, 22 are all porous plate structures. Together with the saw blade cover housing 10, the first, second, and third mesh plates 20, 21, 22 form a dust collection chamber 12. Dust generated during cutting enters the dust collection chamber 12 through the holes in the first, second, and third mesh plates 20, 21, 22 under the action of the dust suction blower, and is ultimately processed or collected by the dust outlet pipe 13. The holes in the first, second, and third mesh plates 20, 21, 22 are all suitable for dust to pass through, resulting in multiple dust collection channels that are less prone to clogging and a large dust collection area, thereby achieving a good dust removal effect. After a period of use, the dust adsorbed on the first, second, and third mesh plates 20, 21, 22 can be easily removed by opening the retractable door 11.

[0029] Please refer to Figures 1 to 2 The first mesh plate 20 is arranged horizontally and is fixed to the inner wall of the saw blade cover shell 10 by fasteners. Through such an arrangement, the first mesh plate 20 and the saw blade cover shell 10 are convenient to install and disassemble. When cleaning the first mesh plate 20, the first mesh plate 20 can be easily removed from the saw blade cover shell 10 for subsequent operations.

[0030] Please refer to Figures 1 to 2 The second mesh plate 21 is set at an angle, and the second mesh plate 21 is fixed to the inner wall of the saw blade cover shell 10 by fasteners. Through such a setting, the second mesh plate 21 and the saw blade cover shell 10 are convenient to install and disassemble. When cleaning the second mesh plate 21, the second mesh plate 21 can be easily removed from the saw blade cover shell 10 for subsequent operations.

[0031] Please refer to Figures 1 to 2 The third mesh plate 22 is vertically arranged and fixed to the inner wall of the saw blade cover shell 10 by fasteners. Through such an arrangement, the third mesh plate 22 and the saw blade cover shell 10 are convenient to install and disassemble. When cleaning the third mesh plate 22, the third mesh plate 22 can be easily removed from the saw blade cover shell 10 for subsequent operations.

[0032] Among them, the first mesh plate 20 is located at the top of the saw blade cover shell 10, the third mesh plate 22 is located on the side of the saw blade cover shell 10, and the first mesh plate 20 and the third mesh plate 22 are located on both sides of the second mesh plate 21. Such an arrangement makes the first mesh plate 20, the second mesh plate 21 and the third mesh plate 22 located in the chip discharge direction of the saw blade, and the dust generated during saw blade cutting can be fully adsorbed into the dust collecting chamber 12.

[0033] In this embodiment, the first, second, and third mesh panels 20, 21, and 22 are secured to the inner wall of the saw blade cover housing 10 via fasteners, which may be fastening bolts or fastening screws 16, for example. In other embodiments, the first, second, and third mesh panels 20, 21, and 22 may be provided with protrusions, and the inner wall of the saw blade cover housing 10 may be provided with a plurality of connection holes. The plurality of connection holes on the inner wall of the saw blade cover housing 10 correspond one-to-one with the protrusions on the first, second, and third mesh panels 20, 21, and 22, respectively. The protrusions and connection holes form an interference fit. In this manner, the first, second, and third mesh panels 20, 21, and 22 are fixedly connected to the inner wall of the saw blade cover housing 10, providing a secure connection and facilitating maintenance and replacement. Alternatively, the protrusions may be provided on the inner wall of the saw blade cover housing 10, in which case the connection holes are provided on the first, second, and third mesh panels 20, 21, and 22, respectively. The connection method of the first mesh plate 20 , the second mesh plate 21 , the third mesh plate 22 and the saw blade cover housing 10 is not limited thereto, as long as it is convenient for disassembly and cleaning.

[0034] Please refer to Figures 1 to 2 The circular saw blade cover provided by the present invention also includes a pressure block 14 and a chip guard 15. The pressure block 14 compresses the chip guard 15 and is fixed to the outer side of the saw blade cover housing 10 via screws 16. The chip guard 15 at least partially extends out of the saw blade cover housing 10. The chip guard 15 can block some of the dust in the direction of the saw blade during cutting, preventing it from scattering. In this embodiment, the chip guard 15 can be made of a flexible material, such as rubber.

[0035] Please refer to Figures 1 to 2 The saw blade cover housing 10 is provided with a mounting hole 17 for mounting a drive motor for driving the saw blade. When in use, the drive motor is fixed to the saw blade cover housing 10 through the mounting hole 17, the saw blade is fixedly connected to the output shaft of the drive motor, and the saw blade cover is located outside the saw blade.

[0036] Please refer to Figures 1 to 2 The dust outlet pipe 13 is located on the side of the saw blade cover housing 10, and the dust outlet pipe 13 is tilted.

The opening and closing door 11 is connected to the saw blade cover housing 10 through a hinge 112, which has a simple structure and is easy to install.

[0038] The circular saw blade cover provided by the utility model has a first mesh plate 20, a second mesh plate 21, and a third mesh plate 22, each of which is a porous plate structure. The first mesh plate 20, the second mesh plate 21, and the third mesh plate 22 form a dust collection chamber 12 with the saw blade cover housing 10. Under the action of the dust suction fan, dust generated during cutting enters the dust collection chamber 12 through the holes in the first mesh plate 20, the second mesh plate 21, and the third mesh plate 22, and is ultimately processed or collected by the dust outlet pipe 13. The holes in the first mesh plate 20, the second mesh plate 21, and the third mesh plate 22 can all be used for dust to pass through, resulting in multiple dust collection channels that are less likely to become clogged. When the fan is operating, the dust collection area is large, thereby achieving a good dust removal effect. After a period of use, the dust adsorbed on the first mesh plate 20, the second mesh plate 21, and the third mesh plate 22 can be easily removed by opening the opening and closing door 11.

[0039] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0040] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
