Electric corkscrew

A corkscrew comprising:

• a casing;
• a downwardly opening socket within the casing, the socket having a vertical axis being dimensioned to receive the neck of a bottle;
• a corkscrew spiral arranged axially within the socket;
• a motor adapted to rotate the spiral in clockwise and anticlockwise directions;
• a battery;
• a sleeve having an axial bore mounted for axial movement within the socket;
• spring means adapted to bias the sleeve downwardly within the socket;
• a control circuit including a microprocessor and a memory;
• a display;
• and an upper position sensor;
• the motor upon actuation causing the spiral to rotate in a first direction to penetrate the cork and withdraw the cork from the bottle neck;
• the axial bore being configured to receive and engage the cork wherein axial splines extend inwardly of the bore to engage the cork preventing rotation of the cork;
• the upper position sensor being adapted to detect when the cork is completely removed from the bottle and to generate a signal to stop rotation of the spiral;
• the microprocessor being in electrical communication with the battery and being charged to determine whether the battery is able to perform sufficient work to open a cork and to provide a signal to the display indicating the number of corks which may be removed using the corkscrew.
