For example, a sewing machine disclosed in patent application number CN201721433059.5 includes a worktable and a main unit fixed to the worktable. A sewing needle is mounted on the main unit, forming a working area between the sewing needle and the worktable. A pressing rod is slidably connected to the end of the worktable near the sewing needle. A transmission mechanism is provided on the worktable, comprising a sliding rod, a spiral groove, and a drive rod. The sliding rod is fixed to the outer wall of the pressing rod, the spiral groove is formed on the outer wall of the drive rod, and the drive rod is rotatably connected to the worktable. The end of the sliding rod away from the pressing rod is placed in the spiral groove, and a blade is connected to the drive rod, located in the working area.

[0050] The dust collection component 3 is connected to the air inlet 40 of the dust filter box 4.

[0051] In this embodiment, during the sewing process, the exhaust fan 5 operates within the dust filter box 4 to generate a negative pressure environment. The dust collection component 3 connects to the negative pressure environment within the dust filter box 4 through the air inlet 40, thereby generating suction. The fabric is placed in the working area of ​​the sewing machine body 2 for sewing operations. Waste materials such as debris, thread ends, lint, and dust generated during the process can be collected by the dust collection component 3 and transported to the dust filter box 4. The waste materials are filtered and collected during the process of passing through the dust filter box 4, while the air is discharged through the air outlet 41. Compared with the prior art, this utility model can effectively collect and treat the waste materials generated during fabric sewing operations, thereby preventing the waste materials from affecting the sewing process and the health of the workers, and improving the work efficiency and safety of sewing operations.

[0052] Example 2:

[0053] This embodiment provides a dust collection structure for a sewing machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: the dust collection component 3 further includes: a fixed base 30, which is set on the workbench 1 and a dust collection pipe 31 is provided on the fixed base 30; a telescopic hose 32, which has a connecting ring 33 at one end and a dust collection cover 34 at the other end.

[0054] One end of the dust collection pipe 31 is connected to the air inlet 40, one end of the telescopic hose 32 is connected to the dust collection pipe 31 through the connecting ring 33, the telescopic hose 32 is connected to the dust collection pipe 31, the dust collection hood 34 is connected to the telescopic hose 32, and the side wall of the connecting ring 33 is sealed to the dust collection pipe 31 through the sealing ring 6.

[0055] Furthermore, the dust collection pipe 31 is connected to the air inlet 40 through a conventional connecting pipe. The dust collection pipe 31 has an internal thread at the end near the connecting pipe, and the connecting ring 33 has an external thread on its outer wall. The connecting ring 33 is installed inside the dust collection pipe 31 through the internal and external threads. The telescopic hose 32 can be stored in the dust collection pipe 31. A step is formed inside the dust collection pipe 31 through the difference in inner diameter. The side wall of the connecting ring 33 is fitted with the surface of the step and a sealing surface is formed by the sealing ring 6. The dust collection cover 34 is located on the side of the dust collection pipe 31 away from the connecting pipe.

[0056] In this embodiment, during the sewing process, the exhaust fan 5 operates within the dust filter box 4 to generate a negative pressure environment. The dust collection component 3 connects to the negative pressure environment within the dust filter box 4 through the air inlet 40, thereby generating suction. The fabric is placed in the working area of ​​the sewing machine body 2 for sewing operations. Waste materials such as debris, thread ends, lint, and dust generated during the process can enter the telescopic hose 32 through the dust collection hood 34 and are ultimately transported to the dust filter box 4 through the dust collection pipe 31 and connecting pipe. After the sewing operation is completed, the telescopic hose 32 can be pulled out of the dust collection pipe 31 by pulling the dust collection hood 34, thereby manually controlling the position of the dust collection hood 34 to collect waste materials scattered in other positions on the workbench 1. Compared with the prior art, this utility model can effectively collect and process waste materials generated during fabric sewing operations, thereby preventing waste materials from affecting the sewing process and the health of workers, and improving the efficiency and safety of sewing operations.

[0057] Example 3:

[0058] This embodiment provides a dust collection structure for a sewing machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: the dust collection box 4 further includes: a filter plate 42, which is disposed inside the dust collection box 4; a dual-head motor 43, which is disposed in the air outlet 41; a transmission component 44, which is disposed inside the dust collection box 4; a cleaning component 45, which is disposed inside the dust collection box 4 and located on the filter surface side of the filter plate 42; and a waste discharge port 46, which is disposed at the bottom of the dust collection box 4 and is provided with a sealing cover.

[0059] One end of the dual-head motor 43 is connected to the exhaust fan 5, and the other end is connected to the transmission component 44. The cleaning component 45 is connected to the transmission component 44 and can clean the filter surface of the filter plate 42 under the drive of the transmission component 44.

[0060] The cleaning component 45 also includes: a central shaft 450, which is connected to the transmission component 44; and a brush plate 451, which has two brush plates symmetrically distributed on both sides of the central shaft 450 along the radial direction of the central shaft 450. Cleaning bristles 452 are provided on the surface of the brush plate 451 opposite to the filter plate 42.

[0061] The end of the cleaning brush bristles 452 contacts the filter surface of the filter plate 42.

[0062] Moreover, the transmission component 44 consists of a conventional reducer and a transmission shaft. The reducer is fixedly installed inside the dust filter box 4. The input end and output end of the reducer are connected to the dual-head motor 43 and the cleaning component 45 respectively through the transmission shaft. The discharge port 46 is located on the filter surface side of the filter plate 42. The sealing cover is a conventional cover structure and can be detachably installed on the discharge port 46 by bolts.

[0063] In this embodiment, after the waste enters the dust filter box 4, it is filtered by the filter plate 42 as the air flows. Then, the air is discharged from the dust filter box 4 through the air outlet 41. At the same time, as the dual-head motor 43 drives the exhaust fan 5 to operate, the transmission component 44 transmits power to the cleaning component 45. The central shaft 450 rotates under the drive of the transmission component 44, causing the brush plate 451 to rotate. Thus, the cleaning brush bristles 452 can clean the filter surface of the filter plate 42, preventing the waste from clogging the filter plate 42. The cleaned waste accumulates at the bottom of the dust filter box 4, and can be cleaned by opening the waste discharge port 46. Compared with the prior art, this utility model can effectively collect and process the waste generated in the fabric sewing operation, thereby preventing the waste from affecting the sewing process and the health of the workers, improving the work efficiency and safety of the sewing operation, and effectively improving the working stability of the dust filter box 4.
