In the invention, the mopping device mainly comprises two parts, namely a mop strip rolling and folding mechanism, a scroll and a mop strip.

The mop strip rolling and folding mechanism mainly aims to roll and fold and store mop strips, when mopping the ground, the mop strips are firstly rolled on the second reel, when mopping the ground, the mop strip rolling and folding mechanism slowly transfers the mop strips rolled on the reel (in a rolling or drawing mode) to the mop strip rolling and folding mechanism, in the process, the mop strips move, the first surfaces of the mop strips contact the ground to be cleaned, the cleaning machine is matched with the ground to clean the ground, the mop strips can be transferred quickly, the ground is cleaned in the transfer motion, and the cleaning machine is not required to be matched with the ground to walk. Because the mop strips are continuously transferred from the second reel to the mop strip rolling and folding mechanism, when one mop strip is already provided with sludge, the mop strip is rolled and moved to be received in the mop strip rolling and folding mechanism, and the subsequent mop strip coming out from the second reel is clean, so that the cleaning machine can continuously mop the floor. When the mop strip on the second reel is rolled to the end, the second reel still continuously rotates, the mop strip in the mop strip rolling and folding mechanism is transferred to the second reel, and the second surface of the mop strip is contacted with the ground to be cleaned. Therefore, in this embodiment, the mop strips are bidirectionally shifted one above the other, and the two surfaces of the mop strips are respectively cleaned on the ground by matching the rotation direction of the second reel. In actual use, after one side of the mop strip is cleaned, although sludge is attached, the other side of the mop strip is clean, and both sides of the mop strip are used in the embodiment, so that one clean mop strip can be used on two sides, and the floor area is twice as much cleaned as that of the mop strip using only one side.

Structure of the cleaning device in the third embodiment, referring to fig. 4, the mop strip rolling and folding mechanism of the present invention has a second reel below and a mop strip rolling and folding mechanism above. The rolling and folding mechanism comprises a pair of pressing wheels 28 rotating in opposite directions, mop strips penetrate through the pair of pressing wheels, a fixed wheel shaft 27 is arranged above the pressing wheels, the mop strips move to the pressing wheels from the fixed wheel shaft and swing left and right on the horizontal plane through the pressing wheels, and in the swinging process, the mop strips continuously penetrate out of the pair of pressing wheels and are stacked on the mop strip rolling and folding mechanism. In the device, a fixed wheel shaft is fixed between a left machine shell and a right machine shell, two side shaft ends of a swinging wheel are fixed at the lower end of a swinging frame, the upper end of the swinging frame is fixed at the shaft ends at two sides of the fixed wheel shaft, and the swinging frame can carry the swinging wheel to swing left and right. When the mop strip is transferred from the mop strip rolling and folding mechanism to the second scroll, the second scroll is used as a driving shaft, and the mop strip rolling and folding mechanism can be operated without action.

In the above example, the mop strip folding mechanism is above and the second reel is below. Preferably, the mop strip on the second reel directly contacts the ground, and the friction force between the mop strip and the ground is increased by the pressure of the second reel.

In another embodiment of the present invention, the reel unit is composed of two reels, i.e., a first reel and a second reel, the first reel is located on the upper side, and the second reel is located on the lower side. Wherein the main purpose of first spool is with mop strip book pile storage, when dragging ground, the mop strip is rolled up on the second spool earlier, when dragging ground, first spool will roll up the mop strip on the spool slowly and shift (wrap up the mode) to first spool on, at this in-process, the mop strip removes, the first face contact of mop strip is to by clear ground, the cooperation cleaning machine is at the walking on ground to clean ground, certainly, the mop strip shifts also can shift fast, clean ground in the transfer motion, need not the walking of cooperation cleaning machine. Because the mop strips are continuously transferred from the second reel to the first reel, when one section of the mop strips is already provided with sludge, the mop strips are rolled and transferred to the first reel, and the mop strips coming out from the second reel are clean, so that the cleaning machine can continuously mop the floor. When the mop strip on the second reel is rolled to the end, the second reel still keeps rotating, at the same time, the mop strip in the first reel is transferred to the second reel, at the same time, the second surface of the mop strip is contacted with the cleaned floor. Therefore, in this embodiment, the mop strips are bidirectionally shifted one above the other, and the two surfaces of the mop strips are respectively cleaned on the ground by matching the rotation direction of the second reel. In actual use, after one side of the mop strip is cleaned, although sludge is attached, the other side of the mop strip is clean, and both sides of the mop strip are used in the embodiment, so that one clean mop strip can be used on two sides, and the floor area is twice as much cleaned as that of the mop strip using only one side.

The mopping device comprises at least two reels, and a mop strip wound between the reels; the reel is movable mounting, specifically is: the reel can carry out radial movement, and the radial movement specifically is: the reel is movable vertically as well as laterally relative to the housing 15. In practical use, when the mop strip on the second scroll is rolled onto the first scroll, the volume of the second scroll is reduced (the volume is the scroll plus the mop strip wrapped outside, when the mop strip is rolled away, the volume is reduced, and when the mop strip is rolled, the volume is increased), but the volume of the first scroll is increased, so that the first scroll is moved towards the second scroll to squeeze the extra space of the second scroll after the first scroll is reduced, and the total space occupied by the two scrolls is unchanged, therefore, in the embodiment, the large space of the mop strip for wrapping the two scrolls is not required to be reserved for the cleaning machine, only the space of the mop strip for wrapping the scroll is required to be designed for the cleaning machine, therefore, in the space occupied design of the cleaning machine, a lot of space is saved, the cleaning machine can be more miniaturized, or the cleaning machine with the same volume can carry more mop strips, more floor is cleaned, and twice floor area is cleaned.

The two exemplary effects are combined, and the technology of the invention can be four times of the mopping area designed by the structure of the conventional cleaning machine.

The first scroll and the second scroll are both fixed on the shell by shaft ends at two ends and do not move radially, and the spacing distance between the first scroll and the second scroll is as follows: when the mop strip is completely rolled on the first reel or the second reel, the maximum stacking thickness of the mop strip on the first reel or the second reel is properly increased, and the gap for the rotation motion is the spacing distance between the first reel and the second reel. Compared with the embodiment that the reel can move in the radial direction, the embodiment occupies a little larger space, but the rotating shaft is not designed on the sliding block but directly arranged on the machine shell, so the stability is better.

In a preferred embodiment, the first reel is disposed above, and the second reel is disposed directly below the first reel. In the transfer process of the mop strip, the second reel and the first reel both move in the radial direction, wherein the radial movement refers to the vertical movement of the reels. Of course, to achieve the effect of the present invention, the second scroll and the first scroll do not have to be arranged in a vertical direction, but may be arranged in a diagonal direction, i.e. in a diagonal direction. The second reel and the first reel can be arranged in a left-right mode, and the second reel and the first reel move in a left-right radial mode.

The first reel or the second reel can be a rotatable shaft, and the mop strip is directly wound on the shaft. Preferably, first spool or second spool comprise two pivots, specifically speaking, first spool comprises two pivots of parallel arrangement to in the course of the work, two pivots rotate in step, and rotation direction and rotation volume one extremely, mop strip 9 is just like driving belt, carries out the transmission with two pivots and connects, that is to say, two pivots are wrapped up in the inboard of mop strip by mop strip, therefore, when a certain pivot is rotating, other pivot synchronous rotation. Preferably, when one shaft rotates, if the mop is used as a drive to drive the other shaft, the transmission efficiency is low, namely: when one of the rotating shafts is a driving rotating shaft 7-1, the second rotating shaft is a driven rotating shaft 7-2, and the driving rotating shaft 7-1 is driven to the driven rotating shaft 7-2 through a mop strip 9, because the driving efficiency of the mop strip is not high, the condition that the rotating amounts of the driving rotating shaft and the driven rotating shaft are inconsistent (the rotating angles or the rotating speeds are different, and the rotating speed of the driven shaft is lower than that of the driving shaft) can be caused, therefore, a connecting transmission belt 7-3 (the transmission belt is preferably a synchronous belt, and synchronous belt wheels are arranged on the driving shaft and the driven shaft) is arranged between the driving shaft and the driven shaft, the end head of the mop strip is fixed on the outer side of the transmission belt 7-3, specifically, the mop strip is a cloth strip which is provided with two end heads, one of the two end heads is fixed on the outer side of the transmission belt 7-3, when the, the mop strip is rolled on the two rotating shafts and wraps the two rotating shafts together. The second reel is also constructed in the same manner as the first reel. Only the other end of the mop strip is fixed on the outer side of the second reel transmission belt.

The first scroll or the second scroll consists of two rotating shafts to form a belt driving state, namely a synchronous rotating state; all the rotating shafts are arranged in parallel, two rotating shafts are horizontally arranged above the rotating shafts, are positioned on the same horizontal plane and are connected through a belt to form a first reel; two reels are arranged below the frame, are positioned on the same horizontal plane and are connected through a belt to form a second reel; the rotating shaft on the upper left side and the rotating shaft on the lower left side are connected with the end heads of the rotating shafts through sliding blocks; the rotating shaft on the right side of the upper part and the rotating shaft on the right side of the lower part are connected with the end of the rotating shaft through sliding blocks.

The casing has about two blocks of metal frames or metal sheet, and the spool setting is between two blocks of casings about to all open the shaft hole on the casing, the spool both ends set up in the shaft hole.

The two ends of the scroll are arranged on the shell through movable claws, and the scroll can move in the radial direction through the movable claws.

Of course, both ends of the scroll are directly fixed on the casing, at the moment, the scroll only rotates and does not move relative to the casing, so that when the mop strip is rolled on the second scroll, the mop strip can pad the second scroll and the ground to be cleaned, the second scroll is lifted, because the second scroll is fixed on the casing of the machine body, the whole floor mopping device is lifted after the second scroll is lifted, even the rear half part of the cleaning machine is lifted, and then the cleaning machine of the invention is in a forward tilting state. When the mop strip is rolled on the first reel, correspondingly, the rear half part of the cleaning machine is lowered, and then the cleaning machine is in a backward tilting state. Thus, when mopping, the floor will incline forwards and incline backwards. The aesthetic appearance of the cleaning machine is affected to some extent. The scheme is different from the scheme that two ends of the scroll are arranged on the shell through the sliding blocks 14, and two ends of the scroll are arranged on the shell through the movable claws. When the two ends of the scroll are arranged on the shell through the sliding blocks 14 or the two ends of the scroll are arranged on the shell through the movable claws, no matter which scroll the mop strip is wound on, the scroll can move up or down relative to the shell or the body of the cleaning machine, so that the shell or the body of the cleaning machine is prevented from being lifted or lowered, and the cleaning machine is used for keeping a horizontal placement posture.

The shaft end of the scroll is provided with a driving wheel and is connected with the driving wheel as power through a driving device. Of course, if the driving wheel is provided with a power device, power does not need to be output from the outside. The purpose of the driving wheel is to rotate the reel so that the mop strip is wound by the reel. The scroll in the invention can also be an automatic scroll, and power is arranged in the scroll, for example, a motor is arranged in a shaft core of the scroll, and a hydraulic power and pneumatic mechanism are arranged in the shaft core, so that the scroll is driven to rotate.

Regarding the cleaning device structure (i.e. the mopping device part):

the scroll is respectively composed of an upper scroll 7 formed by an upper rotating shaft and a lower scroll 8 formed by a lower rotating shaft, and two ends of the mop strip 9 are respectively connected with the upper scroll and the lower scroll and are wound on the scrolls; one side of the mop strip rolled on the lower scroll is contacted with the ground. The axle center (centre of a circle) of upper reel and lower reel is not on same plumb line, but the axis of upper reel and lower reel is parallel, but the axis position staggers that inclines specifically is: the upper scroll is arranged at the upper left, and the lower scroll is arranged at the lower right; or the upper reel is disposed at the upper right and the lower reel is disposed at the lower left. During operation, the relative distance between the upper and lower reels is kept constant, but the lower and upper reels are still subject to radial displacement, in particular to a tilting movement, or to a movement around an arc. When the mop strip is moved, the lower scroll and the upper scroll fill up the space mutually, so that the total occupied space is smaller, and the volume of the machine is reduced.

At this moment, the shaft hole 10 is a sliding groove opened on the housing, and the sliding groove is arranged obliquely, the sliding groove at the end of the upper winding shaft and the sliding groove at the end of the lower winding shaft may not be connected, or may not be on the same straight line (this makes the lower winding shaft form a circular arc movement relative to the upper winding shaft, and the lower winding shaft rotationally moves relative to the upper winding shaft), and meanwhile, the sliding groove at the end of the upper winding shaft and the sliding groove at the end of the lower winding shaft may not be parallel, and the two sliding grooves form a certain included angle. The sliding groove of the upper reel end is arranged from the upper left to the lower right, and the sliding groove of the lower reel end is arranged from the lower right to the upper left. The inclination angle of the chute is 0-45 degrees, and the inclination angle of the chute is 30-45 degrees in the implementation.

The slider 14 connects the upper reel and the lower reel at both ends of the reel end, and keeps the upper reel and the lower reel at a distance from each other and moves synchronously. Therefore, the shaft ends of the upper winding shaft and the lower winding shaft are arranged in the inclined sliding grooves, and therefore the radial movement of the upper winding shaft and the lower winding shaft is also in an inclined direction. The purpose of this is also to keep the machine in operation, keeping the machine body height constant and the mop strips able to contact the surface to be cleaned, by displacing the mop strips and moving the reel accordingly.
