Description

Technical Field

[0001] This application belongs to the technical field of electrospinning production, and specifically relates to a cleaning device for electrospinning nozzles for medical use. Background Art

[0002] Electrospinning is a nanofiber preparation technology that uses high voltage to draw solutions or molten substances into fine fibers. This technology is widely used in various fields, including materials science, biomedicine, environmental engineering, etc. The cleaning device for electrospinning nozzles for medical use is based on electrospinning technology. Micro-nano fiber materials for oral cleaning are prepared using this device, and these materials can be integrated into the oral cleaning device to provide an efficient cleaning effect.

[0003] For example, a patent with the publication number CN218621150U discloses a cleaning device for electrospinning nozzles, which includes a fixed frame and an electrospinning needle. A needle mounting seat and a positive voltage input connector are provided on the surface of the fixed frame. In this cleaning device for electrospinning nozzles, by setting a motor, a driving rod, and a cleaning rod, the driving rod starts to rotate under the drive of the motor. The driving rod drives the cleaning rod to rotate. One end of the cleaning rod gradually approaches the needle. When passing by the electrospinning needle, it contacts the tip of the electrospinning needle, wiping off the liquid droplets and solidified substances on the tip. The driving rod continues to drive the cleaning rod to rotate and gradually move away from the needle until it returns to its original position. The cleaning effect can be achieved in one rotation of the driving rod. The electrospinning needle does not move, and the position of the needle and the electric field are not affected at all during the cleaning process, so the electrospinning process can proceed smoothly. The moving area of the needle during the spinning process is always above the receiving device, avoiding the non-uniformity of the lateral thickness of the rigid electrospun membrane.

[0004] However, this device does not install a component for continuously supplying cleaning liquid for a long time, and it cannot support the device to clean the electrospinning for a long time. It is necessary to stop the machine and manually supplement the cleaning liquid for cleaning by oneself, resulting in a decrease in the operating efficiency of the device. Summary of the Utility Model
