Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a universal dust removal device for sewing machines. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. The sewing machine can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, and products such as leather, plastic, and paper. The stitches are neat, beautiful, flat, and firm. The sewing speed is fast and the use is easy, and it has led to the deriving of art forms such as hand-push embroidery and computer embroidery.

[0003] In the prior art, Chinese patent publication number CN218175321U discloses a dust removal device for a sewing machine, which belongs to the technical field of sewing machines. It solves the problem of poor working efficiency of existing sewing machines. The dust removal device includes a workbench, and the right side of the workbench has an installation cavity. A number of air holes connected to the inner cavity are evenly distributed on the table surface on the right side of the workbench. A rotating shaft is vertically arranged in the installation cavity, and a motor is fixed in the installation cavity. The air holes can directly suck floating objects such as cotton wool and dust directly into the installation cavity from the air holes, so that we do not need to clean the workbench and sewing machine after finishing work. This design greatly improves the working efficiency of the sewing machine.

[0004] However, in actual use of the utility model, the sewing machine dust removal device is used to remove thread ends and debris left after the sewing machine finishes working. The product may not be cleaned thoroughly when used, and the corners around the sewing machine are difficult to clean. The cleaning position cannot be adjusted, and the dust removal device has poor adjustability. It is not convenient to use, so it needs to be improved. Utility Model Content
