This creation belongs to a product for mopping the floor, and in particular refers to a mopping tool with a mop that can be automatically rolled up and replaced.

Mops are essential floor cleaning tools in modern households. There are many styles and structures on the market. One type of flat mop is a mop board on which a mop cloth, wet paper cloth or electrostatic cloth for cleaning is fixed. When replacing the cleaning cloth of this mop, the dirty one needs to be manually removed and replaced with a new one, which is inconvenient and easily contaminated with dirt. A mop with automatic loading and unloading is China's patent case CN106166052, which includes a mop head and a mop handle connected to each other, the upper part of the mop head is a power chamber, a PLC controller, a first motor and a second motor are installed in the power chamber, the lower part of the mop head is a cleaning chamber, a sponge pad is installed at the bottom of the cleaning chamber, a loading box is installed at the front side of the cleaning chamber, and a unloading box symmetrically arranged with the loading box is installed at the rear side of the cleaning chamber, a first material coiling rod and a second material coiling rod are installed in the loading box and the unloading box respectively, and the first material coiling rod and the second material coiling rod rotate under the drive of the corresponding rotating shaft to realize material unloading and winding, and the cleaning chamber A first roller and a second roller are installed between a loading box and a discharging box, respectively, and the first roller is close to a discharging port of the loading box, and the second roller is close to a feeding port of the discharging box. Slide rails I and II are respectively arranged on both sides of the cleaning chamber, and slide rails I and II are respectively arranged on the slide rails I and II. A push rod is arranged at one end of the second winding rod in the discharging box, and the push rod is connected to a spring installed on the inner wall of the discharging box. A lithium battery box is arranged at the end of the mop handle, and the lithium battery box is connected to a control console on the mop handle. The control console is connected to a PLC controller in the power chamber and operates and controls the movements of the first motor and the second motor. A retractable knife holder is installed at the front side of the feeding port of the discharge box, and a cutting blade is arranged on the retractable knife holder. The above-mentioned application case uses two motors to drive two rollers to rotate to achieve the purpose of loading and unloading. At the same time, the mop must be clamped and positioned by the sliding element I and the sliding element II arranged on the sliding rail I and the sliding rail II, and then covered on the sponge pad. After the mop is dirty, it must be cut by a blade. Not only is the structure more complicated, the manufacturing and assembly costs are higher, and the mop must be cut before it can be recycled, which also causes inconvenience in use.

Another practical invention is the "roll-up mop stand" with Taiwan's patent number M435247, which discloses a device that can roll up used dust removal paper or cloth in one direction, and can continuously remove dirt with new dust removal paper or cloth, and can recycle the used dust removal paper or cloth, which is convenient for subsequent treatment and avoids secondary pollution.
