[0013] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] like Figures 1 to 2 As shown, the embodiment of the utility model includes a computer sewing machine head 1, a water tank 3 is provided at the computer sewing machine head 1, and a coil 303 is provided in the water tank 3; the top of the coil 303 is connected to an air inlet pipe 4, and the air inlet pipe 4 is connected to an external air pump, and the bottom end of the coil 303 passes through the bottom of the water tank 3 and is provided with a connector 5 for connecting an air blowing pipe 7; the air blowing pipe 7 is fixed to the computer sewing machine head 1 through a rotating sleeve 6, and the bottom end of the air blowing pipe 7 is L-shaped, and the top end is sealed with the connector 5, and the air outlet end of the air blowing pipe 7 is aligned with the sewing needle 2 of the computer sewing machine head 1.

[0016] like Figure 2 As shown, a water inlet 301 is provided on the top of the water tank 3, a drain outlet 302 is provided on the bottom, and both are provided with a detachable sealing cover to facilitate the replacement of the cooling water in the water tank 3; an internal thread is provided inside the connecting head 5, and an external thread is provided on the top of the air pipe 7. The air pipe 7 is threadedly connected to the connecting head 5, and the air pipe 7 can be rotated to prevent it from affecting the replacement or threading operation of the needle 2.

[0017] When the computer sewing machine is in use, cooling water can be injected into the water tank 3 through the water inlet 301, and the external micro air pump is turned on to pump air into the coil 303 from the air inlet pipe 4, cool it down in the coil 303, and then blow it out through the air blowing pipe 7. Since the end of the air blowing pipe 7 is aimed at the needle 2, the needle 2 can be cooled by blowing air to prevent its high temperature from causing color overflow in the sewing thread.

[0018] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
