Disclosed is a nozzle block applied to an electrospinning device. At least one piercing unit (means of piercing) having a diameter smaller than the inner diameter of a spinning nozzle is coaxially disposed inside the spinning nozzle in order to prevent solidification of a solution at a tip of the spinning nozzle. The present disclosure includes a first cleaning mechanism for cleaning the spinning nozzle by reciprocating the piercing unit and the spinning nozzle relative to each other so that the tip of the spinning nozzle is unclogged, and a second cleaning mechanism for cleaning aggregates deposited around and outside the tip of the spinning nozzle through chemical cleaning and/or physical cleaning when the electrospinning process is temporarily stopped or after the electrospinning process is completed.

Provided is a control method for a yarn route inspection equipment, an electronic device and a storage medium. The method includes: detecting whether a first workstation in an initial yarn route inspection path is in a shoveling state; when the first workstation is not in the shoveling state, controlling the yarn route inspection equipment to inspect the first workstation; when the first workstation is in the shoveling state, controlling the yarn route inspection equipment to bypass the first workstation to inspect a second workstation and mark the first workstation as an uninspected state; and when inspection of the initial yarn route inspection path is completed and there is a workstation in the uninspected state, controlling the yarn route inspection equipment to perform supplementary inspection on the workstation in the uninspected state in the initial yarn route inspection path.
