Abstract

An electrostatic dust-sticky cleaning device comprises a handle; a driving element being a hollow rectangular box body; a pull rod being slidable in a slot of the box body; an interior of the box body being installed with a unidirectional gear; a driving belt winding around the unidirectional gear; a spindle of the unidirectional gear rotatably installed to the driving belt; a cleaning unit including a cylinder roller, a friction pad, and a semi-round cover; a second spindle of the roller being assembled to a third lateral side of the box body of the driving element. When the roller rotates, it will rub the surface of the friction pad so that the surface of the roller will generate static electrons. Thereby the accumulate dusts can be assembled to the gap between the semi-round cover and the roller.

Claims

1. An electrostatic dust-sticky cleaning device comprising:

a handle;

a driving element being a hollow rectangular box body;

the handle being installed to a first lateral side of the box body of the driving element;

a second lateral side of the box body having a slot;

a pull rod slidably installed in the slot;

an interior of the box body being installed with a unidirectional gear;

a driving belt winding around the unidirectional gear;

one end of the driving belt being connected to one end of a spring and another end of the driving belt being connected to the pull rod;

another end of the spring being connected to one end of a metal buffer and another end of the metal buffer being connected to an inner wall of the slot;

a spindle of the unidirectional gear rotatably installed to the driving belt;

the pulling force of the pull rod will drive the driving belt to further drive the unidirectional gear so that the unidirectional gear rotates counterclockwise;

a cleaning unit including a cylinder roller, a friction pad, and a semi-round cover;

a second spindle of the roller being assembled to a third lateral side of the box body of the driving element;

the second spindle being further assembled to a center of the unidirectional gear of the driving element so that when the unidirectional gear rotates, the roller is driven to rotate unidirectionally;

the friction pad being fixed to the third lateral side of the box body;

one side of the friction pad being assembled to a surface of the roller;

when the roller rotates, it will rub the surface of the friction pad so that the surface of the roller will generate static electrons;

one lateral side of the semi-round cover being formed with a third spindle which is pivotally installed to an outer side of the box body of the driving element;

thereby the accumulate dusts can be assembled to the gap between the semi-round cover and the roller.

2. The electrostatic dust-sticky cleaning device as claimed in claim 1, further comprising a knife, a backside of the knife being assembled to one side of the friction pad;

the combination of the knife and the friction pad being formed with a groove;

another lateral side of the semi-round cover being connected to the groove.

3. The electrostatic dust-sticky cleaning device as claimed in claim 2, wherein the knife is made of rubber.

4. The electrostatic dust-sticky cleaning device as claimed in claim 1, wherein the roller is made of plastics.

5. The electrostatic dust-sticky cleaning device as claimed in claim 1, wherein the friction pad is made of natural leather.
