Abstract

A cleaning device with electrostatic sheet auto rolling, comprising: a frame; a power gear set; a roller set, having a first roller, a second roller, a paper feeder roller; and a paper collector roller, arranged axially parallel with each other; and a drive shaft; wherein, the paper feeder roller is coaxially received inside a roller of paper; the first, the second and the paper collector rollers are driven to rotate by the power gear set; the paper collector roller is disposed radial to the paper feeder roller at a side thereof while enabling the first and the second rollers to be arranged therebetween; the drive shaft is enabled to move relative to the frame and perpendicular to the axial direction of the drive shaft; the drive shaft is arranged protruding out of the frame; and the drive shaft, the first and the second rollers are arranged parallel to each other.

Claims

1. A cleaning device, comprising:

a frame;

a power gear set, mounted on the frame to be used for providing a driving force;

a dust cloth;

a roller set, mounted on the frame, being driven to function by the driving force of the power gear set for transporting the dust cloth while enabling the same to be stretched; and

a self-adjusting set, mounted on the frame while capable of moving relative to the frame in a reciprocating manner, wherein an outer surface of the self-adjusting set is in contact with the dust cloth;

wherein the frame further comprises;

a first rack, having a first space formed therein for receiving the roller set, and a hollow section formed at the bottom thereof for enabling the self-adjusting set to protrude out of the frame therethrough;

a second rack, mounted on the top of the first rack for allowing the self-adjusting set to be mounted to the bottom thereof; and

a third rack, disposed at a side of the first rack for allowing a second space to be formed therebetween so as to be provided for receiving the power gear set therein.

2. The cleaning device of claim 1, further comprising:

a wiping unit, provided for performing a cleaning operation upon the surface of the dust cloth.

3. The cleaning device of claim 2, wherein the wiping unit further comprises:

a brush member, coupled to the power gear set for enabling the same to bring along the brush member to rotate and thus brushing through the surface of the dust cloth; and

a tray, disposed below the brush member for receiving miscellaneous objects being removed from the surface of the dust cloth by the brushing of the brush member.

4. A cleaning device, comprising:

a frame;

a power gear set, mounted on the frame to be used for providing a driving force;

a dust cloth;

a roller set, mounted on the frame, being driven to function by the driving force of the power gear set for transporting the dust cloth while enabling the same to be stretched; and

a self-adjusting set, mounted on the frame while capable of moving relative to the frame in a reciprocating manner, wherein an outer surface of the self-adjusting set is in contact with the dust cloth;

wherein the roller set further comprises a plurality of rollers including a first roller, a second roller, a paper feeder roller, and a paper collector roller, being configured in a manner that the first roller, the second roller, the paper feeder roller and the paper collector roller are arranged axially parallel with each other while enabling the first roller, the second roller, and the paper collector roller to be driven to rotate by the driving force of the power gear set, and the paper collector roller is disposed radial to the paper feeder roller at a side thereof while enabling the first and the second rollers to be arranged therebetween in a manner that the first roller is disposed next to the paper feeder roller and the second roller is disposed next to the paper collector roller.

5. A cleaning device, comprising:

a frame;

a power gear set, mounted on the frame to be used for providing a driving force;

a dust cloth;

a roller set, mounted on the frame, being driven to function by the driving force of the power gear set for transporting the dust cloth while enabling the same to be stretched; and

a self-adjusting set, mounted on the frame while capable of moving relative to the frame in a reciprocating manner, wherein an outer surface of the self-adjusting set is in contact with the dust cloth;

wherein the self-adjusting set has a drive shaft that is arranged protruding out of the frame, and the drive shaft has two sliding elements that the two sliding elements, each being configured with at least one block, are arranged respectively at two axial ends of the drive shaft while being inset respectively into two corresponding positioning members; and

a second rack has two protruding pieces that are arranged respectively at positions corresponding to the two positioning members coupling to the two axial ends of the drive shaft, and each of the two protruding pieces is formed with a slot extending in a direction for enabling an included angle to be formed between the extending direction and the axial direction of the drive shaft while enabling the blocks of the two sliding elements to inset into their corresponding slots when the two protruding pieces are coupled to their corresponding positioning members, and thus enabling the blocks to slide inside the corresponding slots in synchronization with the sliding of the sliding elements inside their corresponding positioning members.

6. The cleaning device of claim 5, wherein there is a suspension unit being arranged at a position between each sliding element and its corresponding positioning member.

7. A cleaning device, comprising:

a frame;

a power gear set, mounted on the frame to be used for providing a driving force;

a dust cloth;

a roller set, mounted on the frame, being driven to function by the driving force of the power gear set for transporting the dust cloth while enabling the same to be stretched; and

a self-adjusting set, mounted on the frame while capable of moving relative to the frame in a reciprocating manner, wherein an outer surface of the self-adjusting set is in contact with the dust cloth;

wherein the power gear set further comprises;

a motor;

a gear set, capable of being driven to rotate by the motor and being composed of a plurality of gears including a first gear, a second gear and a paper collector gear, being configured in a manner that the first gear is axially coupled to the first roller, the second gear is axially coupled to the second roller, and the paper collector gear is axially coupled to the paper collector roller, and thereby, the first gear, the second gear and the paper collector gear are capable of respectively bringing along the first roller, the second roller and the paper collector roller to rotate when the gear set is being driven to rotate by the motor.

8. The cleaning device of claim 7, wherein the gear set further comprises a ratchet gear, arranged for mating with the paper collector gear.

9. A cleaning device, comprising:

a frame;

a power gear set, mounted on the frame to be used for providing a driving force;

a dust cloth;

a roller set, mounted on the frame, being driven to function by the driving force of the power gear set for transporting the dust cloth while enabling the same to be stretched; and

a self-adjusting set, mounted on the frame while capable of moving relative to the frame in a reciprocating manner, wherein an outer surface of the self-adjusting set is in contact with the dust cloth;
