ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a compact disc cleaning machine, and more particularly to a machine for cleaning a compact disc such that the compact disc is automatically applied on with a liquid cleaning agent before cleaning, and that the compact disc is automatically dried after cleaning.
BACKGROUND OF THE INVENTION
The compact disc (CD), DVD, VCD are widely used to store the data. The reading of the data stored in the compact disc is done by a laser device. The quality of the data reading may be undermined by the fingerprints, dirt, or other foreign objects, which are often the main culprits of the mechanical breakdown of the laser device.
The conventional machines for cleaning the compact disc are capable of cleaning and drying a compact disc. The cleaning process of the conventional machines involves the manual spreading of a liquid cleaning agent on a compact disc to be cleaned in the machine. The compact disc is cleaned and dried by the machine. The liquid cleaning agent is made of a volatile liquid, which is harmful to the human skin. In addition, the volatile liquid gives off vapor, which contaminates the air of a room in which the cleaning of the compact disc is brought about. It is therefore readily apparent that the volatile cleaning agent is a health hazard unless the improvements are made on the operation of the conventional machines for cleaning the compact disc.
SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide an automatic machine for cleaning a compact disc. The automatic machine of the present invention is free from all deficiencies of the conventional machines described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by an automatic machine comprising a housing, a motor, a transmission mechanism, a disc carrying seat, an application device, a drying device, a first lifting mechanism, a second lifting mechanism, and a control device. The motor is located in the housing and controlled by the control device. The power of the motor is transmitted by the transmission mechanism to drive the disc carrying seat on which a compact disc to be cleaned is rotatably located. The application device is contiguous to the disc carrying seat and is driven by the power of the motor via the transmission mechanism to rotate. The first lifting mechanism is disposed in the housing and is located between the transmission mechanism and the application device to drive the application device to move toward or away from the compact disc. The second lifting mechanism is located between the transmission mechanism and the drying device for driving the drying device to move toward or away from the compact disc which has been cleaned.
The foregoing objective, features and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
