Abstract

Disclosed herein is a piezoelectric sealing cap, including: a piezoelectric element generating displacement by a driving voltage; and a sealing part formed to surround the piezoelectric element and sealing a bottle neck when the piezoelectric element is inserted into the bottle neck.

Claims

1. A piezoelectric sealing cap, comprising:

a piezoelectric element generating displacement by a driving voltage; and

a sealing part formed to surround the piezoelectric element and sealing a bottle neck when the piezoelectric element is inserted into the bottle neck.

2. The piezoelectric sealing cap of claim 1, wherein the sealing part is formed to cover the outer side of the piezoelectric element and is elastically deformed according to the displacement of the piezoelectric element.

3. The piezoelectric sealing cap of claim 1, wherein the sealing part is made of rubber so as to have elasticity.

4. The piezoelectric sealing cap of claim 1, wherein the piezoelectric element includes electrode layers formed on an upper surface and a lower surface thereof and when a driving voltage is applied to the electrode layers, the displacement of the piezoelectric element is generated due to attractive or repulsive force between the internal charges of the piezoelectric element and the driving voltage.

5. The piezoelectric sealing cap of claim 4, wherein a driving terminal of the electrode layer at one side is projected to the electrode layer at the other side in order to apply a driving voltage to the electrode layer.

6. The piezoelectric sealing cap of claim 5, wherein the driving terminal of the electrode layer at one side is formed by penetrating through the sealing part.

7. A piezoelectric sealing cap assembly, comprising:

a piezoelectric element generating displacement by a driving voltage;

a sealing part formed to surround the piezoelectric element and sealing a bottle neck when the piezoelectric element is inserted into the bottle neck; and

a power supply unit applying the driving voltage to the piezoelectric element so that the width of the piezoelectric element is smaller than the width of the bottle neck due to attractive force between the internal charges of the piezoelectric element and the driving voltage.

8. The piezoelectric sealing cap assembly of claim 7, wherein the sealing part is formed to cover the outer side of the piezoelectric element and is elastically deformed according to the displacement of the piezoelectric element.

9. The piezoelectric sealing cap assembly of claim 7, wherein the sealing part is made of rubber so as to have elasticity.

10. The piezoelectric sealing cap assembly of claim 7, wherein when the driving voltage to the piezoelectric device is blocked, attractive force between the internal charges of the piezoelectric element and the driving voltage is lost to increase the widths of the piezoelectric element and the sealing part.

11. The piezoelectric sealing cap assembly of claim 7, wherein the piezoelectric element includes electrode layers formed on an upper surface and a lower surface thereof, and a driving voltage is applied to the electrode layers.

12. The piezoelectric sealing cap assembly of claim 11, wherein a driving terminal of the electrode layer at one side is projected to the electrode layer at the other side in order to apply a driving voltage to the electrode layer.

13. The sealing piezoelectric cap assembly of claim 12, wherein the driving terminal of the electrode layer at one side is formed by penetrating through the sealing part.
