Abstract

According to an embodiment, an electrospinning apparatus includes an electrospinning head and a storage case. The electrospinning head includes a nozzle capable of ejecting a material liquid and is movable between a first move position and a second move position. In the storage case, a storage hollow capable of accommodating a nozzle is formed, and an opening to the outside of the storage hollow is formed in the storage case. The storage case causes the nozzle of the electrospinning head located at the first move position to be arranged at a position separate from the storage hollow and causes the nozzle of the electrospinning head located at the second move position to be accommodated inside the storage hollow.

First claim

What is claimed is:

1. An electrospinning apparatus comprising:
an electrospinning head which is movable between a first move position and a second move position, and which includes a nozzle capable of ejecting a material liquid including a high polymer material;
a storage case inside which a storage hollow capable of accommodating the nozzle of the electrospinning head is formed, an opening of the storage hollow to an outside being formed in the storage case;
a support member configured to support the storage case at an accommodating position and a non-accommodating position different from the accommodating position,
wherein the storage case is configured to be positioned at the non-accommodating position when the nozzle of the electrospinning head is located at the first move position and configured to be positioned at the accommodating position at which the storage case accommodates the nozzle of the electrospinning head located at the second move position on an inside of the storage hollow.

2. The electrospinning apparatus according to claim 1 , further comprising:
a case moving unit which moves the storage case by a force applied by the electrospinning head when the electrospinning head moves to the second move position, and thereby facilitates insertion of the nozzle into the storage hollow of the storage case from the opening.

3. The electrospinning apparatus according to claim 2 , further comprising:
a case retaining unit that retains the storage case at the non-accommodating position in a state in which no force is applied to the case moving unit by the electrospinning head.

4. The electrospinning apparatus according to claim 1 , further comprising:
a tight-contact portion which is provided in the storage hollow of the storage case, and with which the nozzle is in tight contact when the nozzle is accommodated in the storage hollow.

5. The electrospinning apparatus according to claim 4 , wherein the tight-contact portion is a cap including rubber or a sponge that retains a solvent into which the high polymer material included in the material liquid can be dissolved.

6. The electrospinning apparatus according to claim 1 , further comprising:
a supplier that supplies the material liquid to the electrospinning head; and
a power supply source which electrifies the material liquid, and which causes the nozzle to eject the electrified material liquid.

7. The electrospinning apparatus according to claim 2 , wherein the case moving unit is configured to be rotated from the non-accommodating position to the accommodating position to insert the nozzle into the storage hollow of the storage case from the opening by the force applied by the electrospinning head.
