FIG. 5 is a partial schematic view of a further perspective of the web 11. As shown in fig. 1 to 5, the mop provided by the embodiment of the present application includes: mop head 1, stretching device 2, mop pole 3, wiper, extrusion device and folding device.

The mop head 1 comprises a first connecting plate 11 and a second connecting plate 12, the two second connecting plates 12 are hinged to two opposite sides of the first connecting plate 11 through folding devices respectively, for example, the two opposite sides of the first rectangular connecting plate 11 in the drawing 1 are left and right, the stretching device 2 is movably sleeved on the mop rod 3, and the mop head can move up and down along the axis direction of the mop rod 3 under the action of external force.

In a free state (namely, in a mopping state of the mop), the upper surfaces and the lower surfaces of the two connecting plates II 12 and the connecting plates I11 are mutually flush, the whole body is in a flat plate shape, and the lower surface of the mop head 1 is provided with the sheet-shaped wiping material. For example, the wiper may be the mop 13 in fig. 2, or the wiper may be made of other materials such as sponge and collodion, which is not limited in the present application.

Optionally, in other embodiments, the second connecting plates 12 may also be four, may all be rectangular, and are hinged to four side walls of the rectangular first connecting plate 11 through folding devices, respectively.

As shown in fig. 4, a connecting wall 112 is disposed in the middle of the connecting plate 11, the mop rod 3 is rotatably connected to the connecting wall 112, and through grooves 111 for the wipers to reciprocate are respectively disposed on two sides of the connecting wall 112 on the connecting plate 11.

The first connecting plate 11 is approximately rectangular, through grooves 111 are formed in the left side and the right side, close to the middle, of the first connecting plate 11, the through grooves 111 are through holes which penetrate up and down in a popular sense, a connecting wall 112 is arranged in the middle of the through grooves 111 in the two sides, outward-protruding portions 113 are arranged on the outer edges of the middle positions of the front side and the rear side of the first connecting plate 11, and the protruding portions 113 are used for improving structural strength of the first connecting plate 11. The connecting walls 112 are integrally connected with the front side and the rear side of the first connecting plate 11, so that the connecting strength can be improved.

The two wipers are respectively connected to the second connecting plate 12 at one end, for example, at the outer side of the bottom surface of the second connecting plate 12, and connected to the stretching device 2 after passing through the through groove 111 at the adjacent side.

When the wiping object is cleaned or squeezed, the wiping object is pulled through the stretching device 2 to drive the second connecting plate 12 to overcome the elasticity of the folding device and fold the first connecting plate 11, so that the wiping object penetrates through the squeezing device, and the squeezing device squeezes the wiping object. After the cleaning or the wringing is finished, the second connecting plate 12 drives the wiping object to reset under the action of the folding device.

According to the mop provided by the embodiment of the application, the mop head 1 is divided into three parts, namely two connecting plates 12 and a connecting plate 11, and the two connecting plates 12 are hinged on two opposite sides of the connecting plate 11 respectively through folding devices.

One end of each of the two wipers is connected to the second connecting plate 12, the other end of each of the two wipers is connected to the stretching device 2 after penetrating through the through groove 111, when the mop is used by a user, the stretching device 2 can be pulled upwards, the stretching device 2 drives the second connecting plate 12 to overcome the elasticity of the folding device and fold and draw close to the first connecting plate 11, the wipers can be pulled out and penetrate through the extruding device, and the extruding device extrudes and/or cleans the wipers.

Because the first connecting plate 11 and the second connecting plate 12 can be mutually folded, the folding device is folded instead of being stretched under the action of external force, so that the user can use the mop more easily, and the force borne by the folding device and the wiper is smaller, so that the service lives of the folding device and the wiper can be prolonged, and the flat mop has more reliable durability. In addition, when the user extrudes or cleans the wiping object, the use is more labor-saving and convenient, so that the use experience of the user is improved.

When the external force disappears, the wiping object can be automatically reset under the action of the folding device, namely, the wiping object is fixed on the bottom surface (namely, the surface for mopping the floor) of the mop head 1 again, and the user does not need to perform other operations.

Two connecting plates two 12 of this application articulate respectively on the relative both sides of connecting plate one 11 through folding device to two lead to groove 111 set up respectively in the relative both sides of mop pole 3, make the user when 2 pulling two wipes through stretching device, the atress of the connecting plate one 11 left and right sides can be balanced mutually, and the user uses very convenient laborsaving.

As shown in figure 2, the mop cloth 13 is arranged below the first connecting plate 11 and the second connecting plate 12 on the left side and the right side, is rectangular, the width of the mop cloth 13 is matched with that of the through groove 111, a first connecting part 131 hung with the second connecting plate 12 is arranged on the upper surface of the mop cloth 13 close to the left side, the first connecting part 131 is of a rope-shaped structure, and two ends of the first connecting part 131 are fixed on the mop cloth 13. The end part of the right side of the mop 13 extends outwards to form two connecting parts 132 which are hung with the stretching device 2, and the two connecting parts 132 are in rope-shaped structures. The mop cloth 13 may be made of absorbent cotton, the first connecting portion 131 and the second connecting portion 132 of the mop cloth 13 may be made of strong cloth or rope, and in other embodiments, the second connecting portion 132 may be a connecting hole formed in the mop cloth 13.

The present application does not limit the location and type of the extrusion device. For example, the pressing means may be a pressing port, and may be provided on the bottom surface or the back surface of the first connecting plate 11.

As shown in fig. 3 to 5, in the embodiment of the present application, the pressing device includes a first roller 114, a mounting bracket 115, and a connecting wall 112, the first roller 114 is mounted on a groove wall of the through groove 111 on a side opposite to the connecting wall 112 through the mounting bracket 115, and a pressing gap for the wipes to pass through is formed between the first roller 114 and the connecting wall 112. The first roller 114 is disposed on the mounting frame 115, for example, pivotally connected to the mounting frame 115, the first roller 114 can rotate relative to the mounting frame 115, and when the wiper is squeezed or cleaned, the first roller 114 can help the wiper to smoothly pass through the squeezing gap, so that the wiper is very convenient and labor-saving to use.

Alternatively, the mounting bracket 115 may be fixedly mounted on a wall of the through slot 111.

In the embodiment of the present application, the mounting bracket 115 is rotatably connected to, for example, hinged to, a groove wall on which a limiting device for limiting the rotation angle of the mounting bracket 115 is disposed, and the limiting device can limit the rotation of the mounting bracket 115 between a first rotation limit position and a second rotation limit position.

When the wiper moves upwards, the first roller 114 drives the mounting frame 115 to rotate upwards so as to reduce the extrusion gap until the mounting frame 115 reaches a first rotation limit position; when the wiper moves downwards, the first roller 114 drives the mounting frame 115 to rotate downwards to increase the extrusion gap until the mounting frame 115 reaches the second rotation limit position.

That is, the mop 13 moves upward via the first roller 114, which brings the mounting bracket 115 upward, so that the gap between the first roller 114 and the connecting wall 112 is reduced until the mounting bracket 115 reaches the first rotation limit position. When the mop 13 moves downwards through the first roller 114, the mounting bracket 115 is driven to move downwards, so that the gap between the first roller 114 and the connecting wall 112 is enlarged until the mounting bracket 115 reaches the second rotation limit position.

Here, the limiting device can limit the mounting bracket 115 from rotating between the first rotation limit position and the second rotation limit position, and the application does not limit the specific relevant arrangement of the limiting device as long as the limiting function can be performed on the rotation of the mounting bracket 115. For example, the limiting means may be a groove wall of the through groove 111. The mounting bracket 115 may reach a first rotational limit position or a second rotational limit position when the side wall of the mounting bracket 115 and the groove wall abut each other. Of course, the limiting device may be additionally disposed on the first connecting plate 11 to limit the rotation of the mounting frame 115, which is not limited in this application.

Through the above arrangement, since the mounting frame 115 can rotate, and then the size of the extrusion gap can be changed, so that the wringing and/or cleaning of the wiper can be better effected, and the wiper can be helped to smoothly pass through the extrusion gap. When the wiper moves downwards, the first roller 114 drives the mounting frame 115 to rotate downwards, so that the squeezing force applied to the wiper is smaller, the second connecting plate 12 can be more smoothly restored to the initial position, and the wiper is very convenient and labor-saving to use.

As shown in fig. 3 to 5, the mounting bracket 115 has a flat plate shape, and when the mounting bracket 115 reaches the first rotation limit position, the lower surface of the mounting bracket 115 is flush with the lower surface of the first connecting plate 11, and the upper surface of the mounting bracket 115 is flush with the upper surface of the first connecting plate 11. That is, when the first rotational limit position is reached, the mounting bracket 115 is angularly parallel to the link plate 11.

When mopping the ground, under the limiting action of the wiping object and the stretching device 2, the mounting frame 115 can be restored to the first rotation limit position, so that the mounting frame 115 can be kept flush with the connecting plate 11 in the mopping state, the wiping object is kept to be horizontal, and the mopping effect of the mop head 1 is guaranteed.

Further, in the embodiment of the present application, the mop further includes a scraping device disposed on the connecting wall 112 and extending toward the first roller 114, and a pressing gap for the wipe to pass through is formed between the first roller 114 and the scraping device. By providing the wiping device, the wringing and/or cleaning effect for the wipe can be improved.

The type of the sweeping device is not limited in the present application. As shown in fig. 3-5, in the present embodiment, the sweeping device includes a toothed plate 116 and a wiper plate 117.
